PROXY STATEMENT FOR SPECIAL MEETING OF

DYNAMICS SPECIAL PURPOSE CORP.

PROSPECTUS FOR 26,000,000 SHARES OF CLASS A COMMON STOCK

All of the members of the board of directors of Dynamics Special Purpose Corp., a Delaware corporation (“DYNS”), voting on the transaction approved the Business Combination Agreement, dated as of December 19, 2021 (as amended from time to time, including as amended on February 12, 2022 by Amendment No. 1 to Business Combination Agreement, the “Business Combination Agreement”), by and among DYNS, Explore Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of DYNS (“Merger Sub”), and Senti Biosciences, Inc., a Delaware corporation (“Senti”), pursuant to which Merger Sub will merge with and into Senti, with Senti surviving as a wholly-owned subsidiary of DYNS (the “Business Combination”). In connection with the consummation of the Business Combination, DYNS will change its corporate name to “Senti Biosciences, Inc.” In this proxy statement/prospectus, when we refer to “Senti,” we mean Senti Biosciences, Inc. prior to the consummation of the Business Combination, and when we refer to “New Senti” or the “Combined Company,” we mean DYNS, under its new corporate name after the consummation of the Business Combination.

At the effective time of the Business Combination (the “Effective Time”), (i) each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (as defined in this proxy statement/prospectus), (ii) each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, and (iii) each outstanding Senti option (whether vested or unvested) will be converted into an option to purchase a number of shares of Class A Common Stock equal to (A) the number of shares of Senti common stock subject to such option immediately prior to the Effective time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio; in each case, rounded down to the nearest whole share, and rounded up to the nearest whole cent in the case of the exercise price of the Senti options. Holders of shares of Senti common stock and Senti preferred stock may also be eligible to receive up to an aggregate of 2,000,000 shares of Class A Common Stock (the “Contingency Consideration,” which would be common stock of New Senti) based on the share price of New Senti’s common stock following the Business Combination or, in some circumstances, upon a change of control of New Senti. See the section titled “Proposal 1: The Business Combination Proposal” for further information.

Based on an assumed closing date of June 8, 2022 for the Business Combination, the Exchange Ratio is approximately 0.1955 (the calculation of which is described on page 169 of this proxy statement/prospectus). Based on this Exchange Ratio, the total number of shares of Class A Common Stock expected to be issued at the Effective Time in connection with the Business Combination (not including shares that will be issuable upon exercise of outstanding stock options, and not including shares issued in connection with the PIPE Investment (as defined in this proxy statement/prospectus)) is approximately 23,112,889 shares and, assuming that (i) no additional DYNS shares are issued prior to the Effective Time, (ii) there is no exercise of any options to purchase shares of Class A Common Stock that will be outstanding immediately following the Business Combination, (iii) no shares are issued in connection with the Contingency Consideration, and (iv) no shares are issued in connection with the Incentive Plan or the ESPP (each as defined in this proxy statement/prospectus) following the Business Combination, these shares are expected to represent between approximately 39.0% and 52.3% of the issued and outstanding shares of Class A Common Stock (which would be New Senti common stock) and voting power in New Senti immediately following the closing of the PIPE Investment and the Business Combination. These percentages assume, at the low end of the range, that no redemptions from our Trust Account (as defined in this proxy statement/prospectus) occur, and, at the high end of the range, that maximum redemptions from our Trust Account occur, and also that no shares of Class A Common Stock which are subject to Non-Redemption Agreements (as defined in this proxy statement/prospectus) as at the date of this proxy statement/prospectus are redeemed. Please see the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” for further information regarding what constitutes a “maximum redemptions” scenario.

Subject to the same assumptions set forth in the preceding paragraph, and also assuming that 885,377 Founder Shares (as defined in this proxy statement/prospectus) are forfeited by the Sponsor (as defined in this proxy statement/prospectus) and cancelled, with certain DYNS public stockholders concurrently being issued an equivalent number of shares of Class A Common Stock in connection with the Non-Redemption Agreements, DYNS’s public stockholders are expected to hold between 40.6% and 20.5% of the issued and outstanding common stock and voting power in New Senti. These percentages assume, at the low end of the range, that no redemptions from our Trust Account occur, and, at the high end of that range, that maximum redemptions from our Trust Account occur.

Certain privately held entities affiliated with certain of DYNS’s officers and directors will participate in the PIPE Investment by subscribing for an aggregate of 500,000 shares of Class A Common Stock at the time the Business Combination is consummated, on the same terms and conditions as other PIPE Investors (as defined in this proxy statement/prospectus). These entities are also affiliates of our Sponsor. Immediately following the Business Combination and the PIPE Investment, subject to the same assumptions set forth in the two preceding paragraphs, the Sponsor together with its affiliates is expected to collectively hold between approximately 10.3% and 13.7% of the issued and outstanding common stock and voting power in New Senti. These percentages assume, at the low end of the range, that no redemptions from our Trust Account occur, and, at the high end of that range, that maximum redemptions from our Trust Account occur.

Proposals to approve the Business Combination Agreement and the other matters discussed in this proxy statement/prospectus will be presented for approval by DYNS’s stockholders at the special meeting of stockholders of DYNS (the “Special Meeting”) scheduled to be held on June 7, 2022, in virtual format.

DYNS’s Class A Common Stock is currently listed on The Nasdaq Capital Market under the symbol “DYNS.” DYNS intends to apply to list its shares of Class A Common Stock effective upon the consummation of the Business Combination on the Nasdaq Global Market (“Nasdaq”) under the proposed symbol “SNTI.” No shares will trade on Nasdaq (or on The Nasdaq Capital Market) under the symbol “DYNS” following the consummation of the Business Combination. It is a condition of the consummation of the Business Combination that the Class A Common Stock is approved for listing on Nasdaq (subject only to official notice of issuance thereof), but there can be no assurance that such listing condition will be met. If such listing condition is not met, the Business Combination will not be consummated unless the listing condition set forth in the Business Combination Agreement is waived by the parties to that agreement.

DYNS is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as amended, and has elected to comply with certain reduced public company reporting requirements.

OF DYNAMICS SPECIAL PURPOSE CORP.

To Be Held On June 7, 2022

To the Stockholders of Dynamics Special Purpose Corp.:

NOTICE IS HEREBY GIVEN that a special meeting of stockholders (the “Special Meeting”) of Dynamics Special Purpose Corp., a Delaware corporation (“DYNS,” “we,” “our” or “us”), will be held on June 7, 2022, at 10:00 AM, Eastern Time, via live webcast at the following address: https://www.cstproxy.com/dspc/2022.

DYNS recommends that you log in at least 15 minutes before the Special Meeting to ensure you are logged in when the Special Meeting starts. Please note that you will not be able to attend the Special Meeting in person. You are cordially invited to attend the Special Meeting to consider the following proposals (the “Proposals”):

to (a) adopt and approve the Business Combination Agreement, dated as of December 19, 2021 (the “Business Combination Agreement”), as amended on February 12, 2022 by Amendment No. 1 to Business Combination Agreement, among DYNS, Explore Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of DYNS (“Merger Sub”), and Senti Biosciences, Inc., a Delaware corporation (“Senti”), pursuant to which Merger Sub will merge with and into Senti, with Senti surviving the merger as a wholly-owned subsidiary of DYNS (the “Combined Company” or “New Senti”), (b) approve such merger and the other transactions contemplated by the Business Combination Agreement (the “Business Combination”), and (c) adopt and approve each Ancillary Document (as defined in the Business Combination Agreement) to which DYNS is a party and approve all transactions contemplated therein. Subject to the terms and conditions set forth in the Business Combination Agreement, at the effective time of the Business Combination (the “Effective Time”):

(i)

each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to the Exchange Ratio (as defined in the accompanying proxy statement/prospectus);

(ii)

each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio;

(iii)

each outstanding Senti option (whether vested or unvested) will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent); and

(iv)

holders of shares of Senti common stock and Senti preferred stock may also be eligible to receive up to an aggregate of 2,000,000 shares of Class A Common Stock (which would be common stock of New Senti) based on the share price of New Senti common stock following the Business Combination or, in some circumstances, upon a change of control of the Combined Company.

We refer to this proposal as the “Business Combination Proposal.” A copy of the Business Combination Agreement and Amendment No.1 to Business Combination Agreement is attached to the accompanying proxy statement/prospectus as Annex A and Annex AA, respectively;

to approve, assuming the Business Combination Proposal is approved and adopted, a proposed second amended and restated certificate of incorporation (the “Proposed Charter,” a copy of which is attached to the accompanying proxy statement/prospectus as Annex B), which will amend and restate DYNS’s current amended and restated certificate of incorporation (the “Current Charter”), and amended bylaws for the Combined Company (a copy of which is also attached to the accompanying proxy statement/prospectus at Annex B), which will in each case be in effect upon the closing (the “Closing”) of the Business Combination (the “Charter Amendment Proposal”);

to approve, on a non-binding advisory basis, the following material differences between the Proposed Charter and the Current Charter, which are being presented pursuant to guidance of the Securities and Exchange Commission as seven separate sub-proposals (the “Advisory Charter Amendment Proposals”):

(a)

Advisory Charter Amendment Proposal A — to change the corporate name of the Combined Company to “Senti Biosciences, Inc.” on and from the time of the Business Combination;

(b)

Advisory Charter Amendment Proposal B — to increase the authorized shares of common stock of the Combined Company to 500,000,000 shares;

(c)

Advisory Charter Amendment Proposal C — to increase the authorized shares of preferred stock that the Combined Company’s board of directors could issue to 10,000,000 shares;

(d)

Advisory Charter Amendment Proposal D — to provide that certain named individuals be elected to serve as Class I, Class II and Class III directors to serve staggered terms on the board of directors of the Combined Company until their respective successors are duly elected and qualified, or until their earlier resignation, death, or removal, and to provide that the removal of any director be only for cause (and by the affirmative vote of the holders of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote at an election of directors);

(e)

Advisory Charter Amendment Proposal E — to provide that certain amendments to provisions of the Proposed Charter will require the approval of the holders of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote on such amendments, and of the holders of shares of each class entitled to vote thereon as a class;

(f)

Advisory Charter Amendment Proposal F — to make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the closing of its initial public offering (the “Initial Public Offering”), and to omit from the Proposed Charter the various provisions applicable only to special purpose acquisition companies; and

(g)

Advisory Charter Amendment Proposal G — to remove the provisions that allow stockholders to act by written consent as opposed to holding a stockholders meeting;

to approve, assuming the Business Combination Proposal is approved and adopted, for purposes of complying with the applicable provisions of Nasdaq Listing Rule 5635, (a) the issuance of up to 26,000,000 shares of Class A Common Stock in connection with the Business Combination, which amount will be determined as described in more detail in the accompanying proxy statement/prospectus, and (b) the issuance of an aggregate of 6,680,000 shares of Class A Common Stock in a private placement (the “PIPE Investment”) concurrent with the Business Combination (the “Nasdaq Stock Issuance Proposal”);

to approve, assuming the Business Combination Proposal is approved and adopted, the appointment of seven directors who, upon consummation of the Business Combination, will become directors of the Combined Company (the “Director Election Proposal”);

to approve, assuming the Business Combination Proposal is approved and adopted, the Incentive Plan (as defined in the accompanying proxy statement/prospectus), a copy of which is attached to the accompanying proxy statement/prospectus as Annex C, which will become effective as of and contingent on the consummation of the Business Combination (the “Incentive Plan Proposal”);

to approve, assuming the Business Combination Proposal is approved and adopted, the ESPP (as defined in the accompanying proxy statement/prospectus), a copy of which is attached to the accompanying proxy statement/prospectus as Annex D, which will become effective as of and contingent on the consummation of the Business Combination (the “ESPP Proposal”); and

to approve a proposal to adjourn the Special Meeting to a later date or dates if it is determined that more time is necessary or appropriate, in the judgment of the board of directors of DYNS or the officer presiding over the Special Meeting, for DYNS to consummate the Business Combination (the “Adjournment Proposal”).

Only holders of record of Class A Common Stock and Class B Common Stock of DYNS (collectively, the “DYNS Common Stock”) at the close of business on May 3, 2022 (the “Record Date”) are entitled to notice of the Special Meeting and to vote at the Special Meeting and any adjournments or postponements of the Special Meeting. A complete list of DYNS stockholders of record entitled to vote at the Special Meeting will be available for ten (10) days before the Special Meeting at the principal executive offices of DYNS for inspection by stockholders during ordinary business hours for any purpose germane to the Special Meeting.

Pursuant to the Current Charter, DYNS is providing its public stockholders (“Public Stockholders”) with the opportunity to redeem, upon the Closing, the shares of Class A Common Stock (the “Public Shares”) issued in the Initial Public Offering then held by them for cash equal to their pro rata share of the aggregate amount on deposit (as of two business days prior to the Closing) in the trust account (the “Trust Account”) that holds the proceeds (including interest but less franchise and income taxes payable and less the reimbursement prior to Closing of up to $163,889 in franchise taxes paid by DYNS in 2022 provided that such reimbursement shall not reduce the Trust Account balance below $230,000,000) of the Initial Public Offering. For illustrative purposes, based on funds in the Trust Account of $230,089,497.46 on the Record Date, the estimated per share redemption price would have been approximately $10.00. Public Stockholders may elect to redeem Public Shares even if they vote for the Business Combination Proposal. A Public Stockholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, with respect to more than an aggregate of 15% of the Public Shares issued in the Initial Public Offering, without the prior consent of DYNS. In connection with and as partial consideration for DYNS proceeding with the Initial Public Offering, and for the covenants and commitments of DYNS set forth in a letter agreement entered into with our Sponsor (as defined in the accompanying proxy statement/prospectus), but, for the avoidance of doubt, for no other or additional consideration in connection with the Business Combination, DYNS’s Sponsor and DYNS’s other initial stockholders have agreed to waive their redemption rights with respect to any Founder Shares and Private Placement Shares (each as defined in the accompanying proxy statement/prospectus) and any Public Shares they may hold, and the Sponsor has also agreed to waive its redemption rights with respect to any other equity securities it holds, and such shares will be excluded from the pro rata calculation used to determine the per-share redemption price. The Sponsor and DYNS’s other initial stockholders have agreed to vote any Founder Shares, Private Placement Shares and Public Shares owned by them, and the Sponsor has also agreed to vote any other equity securities, in favor of the Business Combination Proposal, which represent approximately 21.9% of the voting power of DYNS as of the Record Date. These holders have also agreed to vote their shares in favor of all other Proposals being presented at the Special Meeting.

Pursuant to DYNS’s bylaws, the presence of the holders of a majority of the shares of DYNS Common Stock entitled to vote, at the Special Meeting or by proxy, will constitute a quorum for the transaction of business at the Special Meeting. Under the Delaware General Corporation Law, shares that are voted “abstain” or “withheld” are counted as present for purposes of determining whether a quorum is present at the Special Meeting. Because the Proposals are “non-discretionary” items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker “non-vote” will be deemed to have occurred for each of the Proposals. Broker “non-votes” will not be counted as present for purposes of determining whether a quorum is present.

The approval of the Business Combination Proposal requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class. The approval of each of the Nasdaq Stock Issuance Proposal, the Incentive Plan Proposal, the ESPP Proposal, the Adjournment Proposal and each of the Advisory Charter Amendment Proposals also requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class. The approval of the Charter Amendment Proposal requires the affirmative vote of the holders of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately, as well as the affirmative vote of the holders of a majority of the issued and outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class.

The approval of the Director Election Proposal requires a plurality vote of the shares of DYNS Class B Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting. “Plurality” means that the

individuals who receive the largest number of votes cast “FOR” are elected as directors. Consequently, any shares not voted “FOR” a particular nominee (whether as a result of an abstention, a direction to withhold authority or a broker non-vote) will not be counted in the nominee’s favor.

If the Business Combination Proposal is not approved, the Charter Amendment Proposal, the Advisory Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal and the ESPP Proposal will not be presented to DYNS stockholders for a vote. The approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal and the ESPP Proposal are preconditions to the Closing.

As of the Record Date, there was $230,089,497.46 in the Trust Account. Each redemption of Public Shares by Public Stockholders will decrease the amount in the Trust Account. DYNS will not redeem Public Shares in an amount that would cause it to have net tangible assets of less than $5,000,001.

Your attention is directed to the proxy statement/prospectus accompanying this notice (including the Annexes thereto) for a more complete description of the proposed Business Combination and related transactions and each of the Proposals. We encourage you to read the proxy statement/prospectus carefully. If you have any questions or need assistance voting your shares, please call our proxy solicitor, Morrow Sodali, at Toll-free (800) 662-5200 or (203) 658-9400 or email at DYNS.info@investor.morrowsodali.com.

SUMMARY TERM SHEET

This Summary Term Sheet and the sections entitled “Questions and Answers About the Proposals” and “Summary of the Proxy Statement/Prospectus” summarize certain information contained in this proxy statement/prospectus, but do not contain all of the information that is important to you. You should carefully read this entire proxy statement/prospectus, including all of the accompanying financial statements and the attached annexes, for a more complete understanding of the matters to be considered at the Special Meeting.

•

DYNS is a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

•

On May 28, 2021, DYNS completed its Initial Public Offering of 23,000,000 shares of Class A Common Stock at a price of $10.00 per share, generating proceeds of $230,000,000 before underwriting discounts and expenses. Simultaneously with the closing of the Initial Public Offering, DYNS closed the Concurrent Private Placement of 715,500 shares of Class A Common Stock at a price of $10.00 per share to the Sponsor, generating proceeds of $7,155,000.

•

their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti is designing its gene circuit platform technologies to be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including hematopoietic stem cells (HSCs), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates currently utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful completion of investigational new drug application (“IND”) enabling studies, Senti expects to file INDs for multiple product candidates starting in 2023.

•

On December 19, 2021, DYNS, Senti and Merger Sub entered into the Business Combination Agreement. Under the terms of the Business Combination Agreement, the parties thereto will enter into a business combination transaction pursuant to which Merger Sub will merge with and into Senti, with Senti surviving as a wholly-owned subsidiary of DYNS.

•

In accordance with and subject to the terms of the Business Combination Agreement, the consideration to be paid in connection with the Business Combination (the Business Combination Consideration) is $240,000,000, which will be paid as equity consideration to the Sellers and the holders of Senti options. The Sellers may also be entitled to the Contingency Consideration. For more information regarding the consideration to be paid in connection with the Business Combination, please see the section entitled “Summary of the Proxy Statement/Prospectus – Business Combination Consideration.”

•

Concurrently with the execution of the Business Combination Agreement, DYNS entered into subscription agreements with the PIPE Investors in respect of the PIPE Investment, pursuant to which the PIPE Investors have collectively subscribed for 6,680,000 shares of Class A Common Stock for an aggregate purchase price equal to $66,800,000. The PIPE Investment will be consummated substantially concurrently with the Closing. It is anticipated that, assuming that no additional shares are issued prior to Closing, upon Closing:

•

the PIPE Investors, who will include certain entities affiliated with certain of DYNS’s officers and directors (who will subscribe for an aggregate of 500,000 shares of Class A Common Stock on the same terms and conditions as all other PIPE Investors), will own approximately 11.3% of the outstanding DYNS Common Stock;

•

the Sellers will own approximately 39.0% of the outstanding DYNS Common Stock;

•

the Sponsor will own approximately 9.4% of the outstanding DYNS Common Stock; and

•

Public Stockholders will own approximately 40.3% of the outstanding DYNS Common Stock.

These levels of ownership interest (i) assume that no Public Shares are elected to be redeemed in connection with the Business Combination, (ii) assume no exercise of any options to purchase shares of Class A Common Stock that will be outstanding immediately following the Business Combination, whether such options are issued under the Incentive Plan or otherwise, (iii) exclude the Contingency Consideration, if any, (iv) exclude the issuance of any shares or other awards in connection with the Incentive Plan or the ESPP following the Business Combination, and (v) assume that 885,377 Founder Shares are forfeited by the Sponsor and cancelled, with the Anchor Investors (which are Public Stockholders) concurrently being issued an equivalent number of shares of Class A Common Stock in connection with the Non-Redemption Agreements (as defined below), as described below. If the actual facts are different from these assumptions, then the levels of ownership interest set forth above will be different. For more information, please see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information.”

•

On February 12, 2022, DYNS, Merger Sub and Senti entered into Amendment No.1 to Business Combination Agreement to, among other things (i) clarify section 5.7 of the Business Combination Agreement with respect to certain parameters of the Incentive Plan, and (ii) restructure certain option

grants made to Senti employees at the time the Business Combination Agreement was signed, to (a) acknowledge that certain of such employees’ option award agreements reflect the fact that their option grants, which are for a number of shares of Senti common stock, are subject to adjustment, and (b) provide that certain of such employees’ options will commence vesting on the grant date (being the date the Business Combination Agreement was signed) while other employees’ options will commence vesting on the Closing Date.

•

Our Board considered various factors in evaluating the Business Combination and determining whether to approve the Business Combination Agreement. For more information about our Board’s decision-making process, as well as other factors, uncertainties and risks considered, see the section entitled “Proposal 1: The Business Combination Proposal — The Board’s Reasons for Approval of the Business Combination.”

•

Pursuant to the Current Charter, Public Stockholders may request that we redeem all or a portion of their Public Shares for cash if the Business Combination is consummated. Public Stockholders may elect to redeem their Public Shares even if they vote “FOR” the Proposal to approve the Business Combination, or any other Proposal. If the Business Combination is not consummated, the Public Shares will be returned to the respective Public Stockholder or their broker, bank or other nominee. If the Business Combination is consummated, and if a Public Stockholder properly exercises their right to redeem all or a portion of their Public Shares, including by timely delivering their shares to Continental, we will redeem such Public Shares for a per-share price, payable in cash, equal to the pro rata portion of the Trust Account, calculated as of two business days prior to the consummation of the Business Combination, including interest but less franchise and income taxes payable and less the reimbursement prior to Closing of up to $163,889 in franchise taxes paid by DYNS in 2022 (provided that such reimbursement shall not reduce the Trust Account balance below $230,000,000). For illustrative purposes, based on funds in the Trust Account of $230,089,497.46 on the Record Date, the estimated per share redemption price would have been approximately $10.00. If a Public Stockholder properly exercises their redemption rights in full, then they will be electing to exchange all of their Public Shares for cash and will not own any shares of the Combined Company. Please see the section entitled “Summary of the Proxy Statement/Prospectus—Redemption Rights of DYNS Stockholders” for further information regarding the redemption rights of Public Stockholders.

•

In addition to voting on the proposal to approve and adopt the Business Combination Agreement and approve the Business Combination, and to approve and adopt each Ancillary Document (as defined in the Business Combination Agreement) to which DYNS is a party and approve all transactions contemplated therein (together, the “Business Combination Proposal”) at the Special Meeting, our stockholders will be asked to vote to approve the following Proposals:

•

assuming the Business Combination Proposal is approved and adopted, the adoption of the Proposed Charter, which will amend and restate the Current Charter, and amended bylaws for the Combined Company, which will, in each case, be in effect upon the Closing (the “Charter Amendment Proposal”);

•

on a non-binding advisory basis, the following material differences between the Proposed Charter and the Current Charter, which are being presented pursuant to guidance of the SEC as seven separate sub-proposals (the “Advisory Charter Amendment Proposals”):

•

Advisory Charter Amendment Proposal A — to change the corporate name of the Combined Company to “Senti Biosciences, Inc.” on and from the time of the Business Combination;

•

Advisory Charter Amendment Proposal B — to increase the authorized shares of common stock of the Combined Company to 500,000,000 shares;

•

Advisory Charter Amendment Proposal C — to increase the authorized shares of preferred stock that the Combined Company’s board of directors could issue to 10,000,000 shares;

•

Advisory Charter Amendment Proposal D — to provide that certain named individuals be elected to serve as Class I, Class II and Class III directors to serve staggered terms on the

vii

New Senti Board until their respective successors are duly elected and qualified, or until their earlier resignation, death, or removal, and to provide that the removal of any director be only for cause (and by the affirmative vote of the holders of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote at an election of directors);

•

Advisory Charter Amendment Proposal F — to make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the closing of the Initial Public Offering, and to omit from the Proposed Charter the various provisions applicable only to special purpose acquisition companies; and

•

Advisory Charter Amendment Proposal G — to remove the provisions that allow stockholders to act by written consent as opposed to holding a stockholders meeting;

•

assuming the Business Combination Proposal is approved and adopted, for purposes of complying with the applicable provisions of Nasdaq Listing Rule 5635, (a) the issuance of up to 26,000,000 shares of Class A Common Stock in connection with the Business Combination, and (b) the issuance of an aggregate of 6,680,000 shares of Class A Common Stock in connection with the PIPE Investment concurrent with the Business Combination (the “Nasdaq Stock Issuance Proposal”);

•

assuming the Business Combination Proposal is approved and adopted, the appointment of seven directors who, upon consummation of the Business Combination, will become directors of the Combined Company (the “Director Election Proposal”);

•

assuming the Business Combination Proposal is approved and adopted, adoption of the Incentive Plan, which will become effective as of and contingent on the consummation of the Business Combination (the “Incentive Plan Proposal”);

•

assuming the Business Combination Proposal is approved and adopted, adoption of the ESPP, which will become effective as of and contingent on the consummation of the Business Combination (the “ESPP Proposal”); and

•

the adjournment of the Special Meeting to a later date or dates if it is determined that more time is necessary or appropriate, in the judgment of the Board or the officer presiding over the Special Meeting, for DYNS to consummate the Business Combination (the “Adjournment Proposal”).

For further information, please see the section entitled “Summary of the Proxy Statement/Prospectus—Additional Matters Being Voted On By DYNS Stockholders. The approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal and the ESPP Proposal are preconditions to the Closing. Each of these Proposals is more fully described in this proxy statement/prospectus, which each DYNS stockholder is encouraged to read carefully and in its entirety.

•

Unless waived by the parties to the Business Combination Agreement, and subject to applicable law, the closing of the Business Combination is subject to a number of conditions set forth in the Business Combination Agreement, including, among others (i) there being at least $150,000,000 in cash available at Closing, (ii) the registration statement, of which this proxy statement/prospectus forms a part, becoming effective in accordance with the Securities Act, (iii) customary bringdown conditions, and (iv) no material adverse effect in respect of either DYNS or Senti having occurred. There can be no assurance that the parties to the Business Combination Agreement would waive any such provision of the Business Combination Agreement. For more information about the closing conditions to the Business Combination, please see the section entitled “Proposal 1: The Business Combination Proposal.”

•

To assist with minimizing redemptions of Public Shares and satisfying the condition to Closing that there be at least $150,000,000 in available cash at Closing, on December 19, 2021, DYNS entered into non-redemption agreements (the “Non-Redemption Agreements”) with the Anchor Investors pursuant which such investors agreed to, among other things, not redeem the Public Shares beneficially owned by them and to not, subject to certain exceptions, transfer such Public Shares. These commitments apply in respect of 7,968,483 Public Shares in the aggregate as at April 29, 2022. In connection with these commitments from the Anchor Investors, the Sponsor has agreed to forfeit 885,377 Founder Shares and DYNS has agreed to cancel such Founder Shares and concurrently issue to such investors an equivalent number of shares of Class A Common Stock, in each case, at or promptly following Closing, thereby potentially increasing the Anchor Investors’ ownership interest in New Senti. The potential issuance of such shares of Class A Common Stock to the Anchor Investors is the only consideration which they will potentially receive in connection with their agreement not to redeem or (subject to certain exceptions) transfer their Public Shares. On May 9, 2022, DYNS, the Sponsor and the Anchor Investors agreed to amend the Non-Redemption Agreements such that the number of shares of Class A Common Stock to which each Anchor Investor may be entitled equals 11.111% of the number of Public Shares such Anchor Investor holds at the time the Business Combination is consummated (as opposed to when the Non-Redemption Agreement was signed). For more information about the Non-Redemption Agreements, please see the section entitled “Proposal 1: The Business Combination Proposal – Related Agreements – Non-Redemption Agreements.”

•

The proposed Business Combination, including our business following the Business Combination, involves numerous risks. For more information about these risks, please see the section entitled “Risk Factors.”

•

When you consider the recommendation of our Board in favor of approval of the Business Combination Proposal and the other Proposals included herein, you should keep in mind that the Sponsor and our directors have interests in such Proposals that are different from, or in addition to, those of our stockholders generally. Our Board was aware of and considered these interests, among other matters, in evaluating and negotiating the Business Combination Agreement and the other transaction agreements and in recommending to our stockholders that they vote in favor of the Proposals presented at the Special Meeting, including the Business Combination Proposal. DYNS stockholders should take these interests into account in deciding whether to approve the Proposals presented at the Special Meeting, including the Business Combination Proposal. For further information, please see the section entitled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination.”

QUESTIONS AND ANSWERS ABOUT THE PROPOSALS

The questions and answers below highlight only selected information from this proxy statement/prospectus and only briefly address some commonly asked questions about the Special Meeting and the Proposals to be presented at the Special Meeting, including with respect to the proposed Business Combination. The following questions and answers do not include all the information that may be important to DYNS stockholders. DYNS stockholders are urged to read this entire proxy statement/prospectus, including the Annexes and the other documents referred to herein.

QUESTIONS AND ANSWERS ABOUT THE BUSINESS COMBINATION

Q:	What is the Business Combination?

A:	DYNS and Senti have entered into the Business Combination Agreement, pursuant to which Merger Sub will merge with and into Senti, with Senti surviving the Business Combination as a wholly-owned subsidiary of DYNS.

Q:	Why am I receiving this proxy statement/prospectus?

DYNS and Senti have agreed to a Business Combination under the terms of the Business Combination Agreement that is described in this proxy statement/prospectus. A copy of the Business Combination Agreement is attached to this proxy statement/prospectus as Annex A, and DYNS encourages its stockholders to read it in its entirety. DYNS’s stockholders are being asked to consider and vote upon a proposal to approve the Business Combination Agreement, which, among other things, provides for the Business Combination whereby Merger Sub will merge with and into Senti, with Senti surviving the Business Combination as a wholly-owned subsidiary of DYNS. See the section entitled “Proposal 1: The Business Combination Proposal” for further information.

This document is a proxy statement because the Board is soliciting proxies using this proxy statement/prospectus from DYNS stockholders. It is a prospectus because DYNS, in connection with the Business Combination, is offering shares of Class A Common Stock in exchange for the outstanding shares of Senti common stock and Senti preferred stock and as consideration for the Senti options (via the conversion of such options into options to purchase shares of Class A Common Stock). See the section entitled “Proposal 1: The Business Combination Proposal” for further information.

Q:	What is the Business Combination Consideration and what will Senti stockholders and holders of Senti options receive in the Business Combination?

A:	If the Business Combination is completed, Senti stockholders (the Sellers) and holders of Senti options will receive the following equity consideration, which is referred to collectively as the “Business Combination Consideration”:

•

Each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding Senti option (whether vested or unvested) will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option immediately prior to

the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent).

The Business Combination Consideration is valued at $240,000,000 based on a price for Class A Common Stock of $10.00 per share, as negotiated with Senti and set forth in the Business Combination Agreement. Based on the number of shares of Senti common stock and Senti preferred stock outstanding and the number of shares of Senti common stock underlying outstanding Senti options, in each case as of the Record Date, the total number of shares of Class A Common Stock expected to be issued as Business Combination Consideration is 24,000,000 shares (of which approximately 23,112,889 shares are expected to be issued at Closing to the Sellers). Following the Closing, the Sellers may also be eligible to receive Contingency Consideration of up to an aggregate of 2,000,000 shares of Class A Common Stock (which would be shares of New Senti Common Stock) based on the share price of New Senti Common Stock following the Business Combination or, in certain circumstances, upon a change of control of New Senti. Assuming the same $10.00 per share price as set forth above, the potential value of the Contingency Consideration is $20,000,000. For further information, please see the section titled “Proposal 1: The Business Combination Proposal — Structure of the Business Combination.”

Q:	What equity stake will non-redeeming Public Stockholders, the PIPE Investors, the Sellers and our Sponsor hold in New Senti following the consummation of the Business Combination and the PIPE Investment and what is the expected pro forma equity value of New Senti at the Closing?

The equity stake held by our non-redeeming Public Stockholders, the PIPE Investors (who will include certain entities affiliated with certain of DYNS’s officers and directors), the Sellers and our Sponsor in New Senti immediately following consummation of the Business Combination and the PIPE Investment will depend on the number of redemptions from our Trust Account by Public Stockholders at the Closing as well as various other factors, as described in the assumptions set forth below. Approximate equity stakes for each of these stockholder groups upon consummation of the Business Combination and the PIPE Investment, and their corresponding approximate collective voting power in New Senti, are set forth in the table below in respect of four redemption scenarios: (1) “Scenario A,” in which there are no redemptions of our Public Shares; (2) “Scenario B,” in which 25% of our Public Shares which are not subject to Non-Redemption Agreements as at the date of this proxy statement/prospectus are redeemed; (3) “Scenario C,” in which 75% of our Public Shares which are not subject to Non-Redemption Agreements as at the date of this proxy statement/prospectus are redeemed, and (4) “Scenario D,” in which there are maximum redemptions from our Trust Account. For further information on what constitutes a “maximum redemptions” scenario, please see the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information.” All else being equal, if any Public Stockholders exercise their redemption rights, then the percentage of New Senti Common Stock held collectively by all non-redeeming Public Stockholders will decrease and the percentage of New Senti Common Stock held by the PIPE Investors, the Sellers and our Sponsor will increase, in each case, relative to the percentage held if no Public Shares are redeemed.

Each of the scenarios presented below (i) assumes that no additional shares of DYNS Common Stock are issued prior to Closing, (ii) assumes there is no exercise of any options to purchase shares of Class A Common Stock that will be outstanding immediately following the Business Combination, whether such options are issued under the Incentive Plan or otherwise, (iii) excludes the Contingency Consideration, if any, (iv) excludes the issuance of any shares or other awards in connection with the Incentive Plan or the ESPP following the Business Combination, and (v) assumes that 885,377 Founder Shares are forfeited by the Sponsor and cancelled, with the Anchor Investors (which are Public Stockholders) concurrently being issued an equivalent number of shares of Class A Common Stock in connection with the Non-Redemption Agreements, as described in the section of this proxy statement/prospectus entitled “Summary Term Sheet.”

The table set forth below also states the anticipated pro forma equity value of New Senti for each of the scenarios described above. These pro forma equity values reflect an assumed price for New Senti Common Stock of $10.00 per share, being the price per share negotiated with Senti and set forth in the Business Combination Agreement for shares of Class A Common Stock to be issued as Business Combination Consideration (as described in the preceding question entitled “What is the Business Combination Consideration and what will Senti stockholders and holders of Senti options receive in the Business Combination?”). The pro forma equity values include the equity consideration to be issued to the Sellers at Closing (being approximately 23,112,889 shares of Class A Common Stock, or $231,128,890 of the total $240,000,000 in Business Combination Consideration, based on the assumed price of $10.00 per share) but do not include equity consideration payable to the holders of outstanding Senti options. The number of Public Shares redeemed by Public Stockholders with cash from our Trust Account at Closing is not, all else being equal, expected to materially affect the equity value per share of New Senti Common Stock held by non-redeeming Public Stockholders as at the time immediately following the Closing, as each redemption will result in (x) the cancellation of one Public Share, and (y) the payment of approximately $10.00 to the redeeming Public Stockholder (given that, based on funds in the Trust Account of $230,089,497.46 on the Record Date, the estimated per share redemption price would have been approximately $10.00) and, accordingly, such funds will not be available to the Combined Company or reflected in its financial statements following the Closing. You should note, however, that the level of redemptions of Public Shares from our Trust Account may affect the market price for shares of New Senti Common Stock following the Closing in ways which we cannot predict. For further information, please refer to the section of this proxy statement/prospectus entitled “Risk Factors — Redemptions of Public Shares by Public Stockholders may affect the market price of New Senti Common Stock.”

xii

The ownership percentages set forth below for non-redeeming Public Stockholders and all other New Senti stockholders may be diluted, all else being equal, in the event that (1) options for New Senti Common Stock outstanding following the Closing are exercised, or (2) shares of New Senti Common Stock are issued in connection with the Contingency Consideration. The extent of possible dilution in connection with the Contingency Consideration is set forth in the table below. The issuance of any shares or other awards in connection with the Incentive Plan or the ESPP following the Business Combination would also have a dilutive effect on New Senti stockholders’ ownership percentages, all else being equal, however, the magnitude of any such potential issuances is not known as at the date of this proxy statement/prospectus.

As at the date of this proxy statement/prospectus, there are 23,000,000 Public Shares issued and outstanding. Of those shares, 7,968,483 are subject to Non-Redemption Agreements as at April 29, 2022. The numbers set forth in this column assume that 3,757,879, or approximately 25%, of the 15,031,517 Public Shares that are not subject to Non-Redemption Agreements as at the date of this proxy statement/prospectus are redeemed at $10.00 per share.

(6)

PIPE Investors include certain entities affiliated with certain members of our Board who will subscribe for an aggregate of 500,000 shares of Class A Common Stock in the PIPE Investment on the same terms and conditions as other PIPE Investors. These entities are also affiliates of our Sponsor. Immediately following the Business Combination and the PIPE Investment, our Sponsor and its affiliates are expected to collectively hold between approximately 10.3% and 13.7% of the New Senti Common Stock and corresponding voting power (assuming, at the low end of that range, that no redemptions from our Trust Account occur, and, at the high end of that range, that maximum redemptions from our Trust Account occur, and subject to all of the other assumptions set forth above in respect of the scenarios displayed in the table above).

(7)

The total number of shares of Class A Common Stock which may be issued as Business Combination Consideration is 24,000,000 shares. Approximately 23,112,889 of these shares are expected to be issued at Closing to the Sellers, with the remaining shares being consideration paid for Senti options outstanding at Closing (which options will, at Closing, convert into options to acquire such number of shares of Class A Common Stock (which will be shares of New Senti Common Stock)).

(8)

The Sponsor’s equity interests following the Closing are expected to comprise, as at the date of this proxy statement/prospectus, 715,500 Private Placement Shares and 4,864,623 Founder Shares (being the 5,750,000 Founder Shares the Sponsor holds as at the date of this proxy statement/prospectus less 885,377 Founder Shares which the Sponsor expects to forfeit in connection with the Non-Redemption Agreements). Certain entities affiliated with members of our Board are PIPE Investors and affiliates of our Sponsor, and such entities have subscribed for an aggregate of 500,000 shares of Class A Common Stock in connection with the PIPE Investment on the same terms and conditions as other PIPE Investors.

(9)

Excluding the effect of any “potential additional sources of dilution,” as set forth in the table, which potential additional sources of dilution are subject to certain conditions being satisfied, as set forth in the section of this proxy statement/prospectus entitled “Proposal 1: The Business Combination Proposal — Structure of the Business Combination.”

(10)

Assumes that the Sellers receive Contingency Consideration of an aggregate of 2,000,000 shares of Class A Common Stock (which would be shares of New Senti Common Stock) following the Closing. The issuance of these shares is subject to certain conditions being satisfied, as set forth in the section of this proxy statement/prospectus entitled “Proposal 1: The Business Combination Proposal — Structure of the Business Combination.” The issuance of these shares would not result in any cash inflow to New Senti and therefore would not increase the company’s total equity value at the time of issuance, but would, all else being equal, result in the per share equity value of New Senti Common Stock decreasing. The “voting power” column sets forth the percentage of New Senti’s total issued share capital attributable to shares issued in connection with the Contingency Consideration.

The anticipated ownership of New Senti’s securities set forth above, including the potential effect of any dilutive events, is accurate, subject to the assumptions and exclusions set forth above, as of the date of filing of this proxy statement/prospectus, and does not take into account any transactions that may be entered into after the date hereof unless explicitly set forth above. If the actual facts differ from our assumptions, the numbers of shares and ownership percentages set forth above, including the anticipated equity stake of non-redeeming Public Stockholders in New Senti following the Business Combination and PIPE Investment, will be different.

You should read the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information” for further information.

Q:	When do you expect the Business Combination to be completed?

It is currently anticipated that the Business Combination will be consummated promptly following the Special Meeting, which is set for June 7, 2022; however, the Special Meeting could be adjourned, as described herein. DYNS cannot assure you of when or if the Business Combination will be completed, and it is possible that factors outside of the control of DYNS and Senti could result in the Business Combination being completed at a different time or not at all. DYNS must first obtain the approval of its stockholders for

xiv

certain of the Proposals set forth in this proxy statement/prospectus before consummating the Business Combination.

Q:	What happens if the Business Combination is not consummated?

If DYNS does not complete the Business Combination with Senti, for whatever reason, DYNS will search for another target business with which to complete a business combination. If DYNS does not complete the Business Combination with Senti or another business combination by May 28, 2023 (or such later date as may be approved by DYNS stockholders in an amendment to its Current Charter), DYNS must redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to DYNS to pay its franchise and income taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then-outstanding Public Shares. The Sponsor has waived any rights it may have with respect to any monies held in the Trust Account or any other asset of DYNS as a result of any liquidation of DYNS with respect to the Founder Shares and Private Placement Shares and, accordingly, in the event a business combination is not effected by DYNS in the required time period, the Founder Shares and Private Placement Shares held by the Sponsor would be worthless.

Q:	Did the Board obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

A:	No, the Board did not obtain a third-party valuation or fairness opinion in respect of the proposed Business Combination with Senti. Consequently, you have no assurance from an independent source that the price proposed to be paid for Senti is fair from a financial point of view.

Q:	Will any DYNS securities have registration rights following the consummation of the Business Combination?

Yes. Founder Shares, Private Placement Shares, shares of Class A Common Stock issued to PIPE Investors in connection with the PIPE Investment and shares of Class A Common Stock issued to Anchor Investors in connection with the Non-Redemption Agreements will have registration rights following the consummation of the Business Combination. In total, after the consummation of the Business Combination, an aggregate of 13,145,500 shares of New Senti Common Stock will be subject to registration rights, comprising 715,500 Private Placement Shares, 4,864,623 Founder Shares, 885,377 shares of Class A Common Stock issuable to Anchor Investors and 6,680,000 shares of Class A Common Stock issuable to PIPE Investors. For further information, please see the section of this proxy statement/prospectus entitled “DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations – Commitments and Contingencies.”

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING

Q:	Why is the Special Meeting a virtual, online meeting?

As a part of our precautions regarding the COVID-19 pandemic, we have decided to hold the Special Meeting solely online. We believe that hosting a virtual meeting in the current environment will facilitate stockholder attendance and participation by enabling stockholders to participate from any location around the world and, in doing so, improve our ability to communicate more effectively with our stockholders. We have designed the virtual meeting to provide substantially the same opportunities to participate as you would have at an in-person meeting.

Q:	How do I attend a virtual meeting?

A:	We are pleased to use the virtual meeting format to facilitate stockholder attendance, voting and questions by leveraging technology to communicate more effectively and efficiently with our stockholders. This

format allows stockholders to participate fully from any location, without the cost of travel. As a registered stockholder, along with this proxy statement/prospectus, you received a proxy card from Continental, DYNS’s transfer agent, which contains instructions on how to attend the virtual Special Meeting, including the URL address and your control number. You will need your control number for access. If you do not have your control number, contact Continental at (917) 262-2373, or email Continental at proxy@continentalstock.com.

You can pre-register to attend the virtual Special Meeting starting on May 31, 2022 (five business days prior to the meeting). Enter the following URL address into your browser https://www.cstproxy.com/dspc/2022, then enter your control number, name and email address. Once you pre-register, you can vote or enter questions in the chat box. At the start of the Special Meeting, you will need to re-login using the same control number and, if you want to vote during the meeting, you will be prompted to enter your control number again.

Beneficial owners who own their Class A Common Stock through a bank, broker or other nominee will need to contact Continental to receive a control number. If you plan to vote at the Special Meeting, you will need to have a legal proxy from your broker, bank or other nominee or, if you would like to join and not vote, Continental can issue you a guest control number with proof of ownership. Either way, you must contact Continental at the number or email address above for specific instructions on how to receive the control number. Please allow up to 72 hours prior to the meeting for processing your control number.

If you do not have internet capabilities, you can only listen to the Special Meeting by dialing 1-800-450-7155 (toll-free, within the U.S. and Canada) or 1-857-999-9155 (with toll, outside the U.S. or Canada) and when prompted, enter the pin 6145931. This method supports listening only, so you will not be able to vote or ask questions during the Special Meeting. A replay of the Special Meeting will be made available promptly after the meeting at https://www.cstproxy.com/dspc/2022 and remain available for at least one year from the date it is made available.

Q:	How do I ask questions during the Virtual Special Meeting?

Stockholders may submit questions during the Special Meeting using the “Ask a Question” field on the virtual meeting website. You will need to log in with your control number found on your proxy card to submit a question. Time has been allocated on the agenda to respond to questions submitted during the Special Meeting. Questions we do not answer during the Special Meeting will be answered in writing and posted at https://link.zixcentral.com/u/7f7f31e0/8NRmGT7P7BGCwZLBhnsoMg?u=https%3A%2F%2Fwww.dspc.bio.

If you encounter difficulties during the check-in or meeting time, we have technicians available to help you. The technical support contact information will be posted on the virtual meeting login page.

Q:	Are there any other matters being presented to DYNS stockholders at the Special Meeting?

A:	In addition to voting on the Business Combination Proposal, assuming it is approved and adopted, the stockholders of DYNS will vote on each of the other Proposals described in the section above entitled “Summary Term Sheet.”

DYNS will hold the Special Meeting to consider and vote upon these Proposals. This proxy statement/prospectus contains important information about the proposed Business Combination and the other matters to be considered at the Special Meeting. Stockholders should read it carefully.

Consummation of the Business Combination is conditioned on approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election

xvi

Proposal, the Incentive Plan Proposal and the ESPP Proposal (and each such Proposal is cross-conditioned on the approval of such other Proposals). If any of these Proposals is not approved, the other Proposals will not be presented to stockholders for a vote.

The vote of stockholders is important. DYNS stockholders are encouraged to vote as soon as possible after carefully reviewing this proxy statement/prospectus.

Q:	What will happen to DYNS’s securities upon consummation of the Business Combination?

DYNS’s Class A Common Stock is currently listed on Nasdaq under the symbol “DYNS.” Upon the Closing, the Combined Company will have one class of common stock, which will be listed on Nasdaq under the symbol “SNTI.” Public Stockholders who do not elect to have their Public Shares redeemed for a pro rata share of the Trust Account need not submit Public Shares, and such shares of stock (which will be New Senti Common Stock following the Closing) will remain outstanding. Each outstanding share of Class B Common Stock, by its terms, will automatically convert into one share of Class A Common Stock upon the Closing (which will be New Senti Common Stock).

Q:	Why is DYNS proposing the Business Combination?

A:	DYNS was organized to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses.

On May 28, 2021, DYNS completed its Initial Public Offering of shares of Class A Common Stock (the Public Shares) at a price of $10.00 per share, raising total gross proceeds of $230 million. Since its Initial Public Offering, DYNS’s activity has been limited to the evaluation of business combination candidates.

Senti’s mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, Senti has built a synthetic biology platform that it believes may enable it to program next-generation cell and gene therapies with what it refers to as “gene circuits.” These gene circuits, which Senti created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Senti aims to design and optimize gene circuits through its Design-Build-Test-Learn Engine, or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti is designing its gene circuit platform technologies to be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including hematopoietic stem cells (HSCs), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates currently utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful completion of IND-enabling studies, Senti expects to file IND applications for multiple product candidates starting in 2023.

Based on its due diligence investigations of Senti and the industry in which Senti operates, including the financial and other information provided by Senti in the course of the negotiations in connection with the Business Combination Agreement, DYNS believes that Senti has an appealing market opportunity and growth profile and a compelling valuation. As a result, DYNS believes that the Business Combination with Senti will provide DYNS stockholders with an opportunity to participate in the ownership of a company with significant value. See the section entitled “Proposal 1: The Business Combination Proposal — The Board’s Reasons for Approval of the Business Combination.”

Q:	Do I have redemption rights?

If you are a DYNS stockholder holding Public Shares (a Public Stockholder), you have the right to demand that DYNS redeem your Public Shares for a pro rata portion of the cash held in the Trust Account. We sometimes refer to these rights to demand redemption of the Public Shares as “redemption rights.”

xvii

Notwithstanding the foregoing, a DYNS stockholder, together with any affiliate or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13 of the Exchange Act), will be restricted from exercising redemption rights with respect to more than an aggregate of 15% of the Public Shares without the prior consent of DYNS.

The underwriting fees payable in connection with our Initial Public Offering (some of which the underwriter agreed to defer at the time the Initial Public Offering was consummated) are fixed regardless of the level of redemptions from our Trust Account in connection with the Business Combination. Please see the section of this proxy statement/prospectus entitled “Summary of the Proxy Statement/Prospectus – Underwriting Fees as a Percentage of Initial Public Offering Proceeds Net of Redemptions” for further information.

Q:	How do I exercise my redemption rights?

A Public Stockholder may exercise redemption rights regardless of whether they vote on the Business Combination Proposal or if they are a stockholder on the Record Date. If you are a Public Stockholder and wish to exercise your redemption rights, you must demand that DYNS redeem your Public Shares for cash and deliver your Public Shares to DYNS’s transfer agent, Continental, at Continental Stock Transfer & Trust Company, One State Street Plaza, 30^th Floor, New York, New York 10004, Attn: Mark Zimkind, physically or electronically using mzimkind@continentalstock.com, at least two business days before the Special Meeting, or June 3, 2022. Rather than delivering your Public Shares directly to Continental, you may also deliver your Public Shares either physically or electronically through DTC to Continental at least two business days before the Special Meeting. Any Public Stockholder seeking redemption will be entitled to a full pro rata portion of the amount then in the Trust Account (which, for illustrative purposes, was $230,089,497.46, or approximately $10.00 per share, as of the Record Date), including interest earned but less any owed but unpaid franchise and income taxes and less the reimbursement prior to Closing of up to $163,889 in franchise taxes paid by DYNS in 2022 (provided that such reimbursement shall not reduce the Trust Account balance below $230,000,000). Such amount will be paid promptly upon consummation of the Business Combination. There are currently no owed but unpaid franchise or income taxes on the funds in the Trust Account.

Any request for redemption, once made by a Public Stockholder, may be withdrawn at any time prior to the time the vote is taken with respect to the Business Combination Proposal at the Special Meeting. If you deliver your Public Shares for redemption directly to Continental, or deliver your Public Shares either physically or electronically through DTC to Continental, and later decide prior to the Special Meeting not to elect redemption, you may request that Continental return the shares (physically or electronically). You may make such request by contacting Continental at the phone number, address or email address set forth above.

Any written demand of redemption rights must be received by Continental at least two business days prior to the vote taken on the Business Combination Proposal at the Special Meeting. No demand for redemption will be honored unless the Public Stockholder’s stock has been delivered (either physically or electronically) to Continental.

Q:	What is a Non-Redemption Agreement?

In an effort to reduce the number of redemptions of Public Shares at Closing, DYNS entered into Non-Redemption Agreements with the Anchor Investors. Pursuant to the Non-Redemption Agreements, the Anchor Investors agreed to, among other things, not redeem the Public Shares beneficially owned by them as at the date the Non-Redemption Agreements were signed, and to not, subject to certain exceptions, transfer such Public Shares. These commitments apply in respect of 7,968,483 Public Shares in the aggregate as at April 29, 2022. In connection with these commitments from the Anchor Investors, the Sponsor has agreed to forfeit 885,377 Founder Shares and DYNS agreed to cancel such Founder Shares and concurrently issue to such investors an equivalent number of shares of Class A Common Stock, in each case, at or promptly following Closing, thereby potentially increasing the Anchor Investors’ ownership interest in New Senti. The potential issuance of such shares of Class A Common Stock to the Anchor

xviii

Investors is the only consideration which they will potentially receive in connection with their agreement not to redeem their Public Shares. On May 9, 2022, DYNS, the Sponsor and the Anchor Investors agreed to amend the Non-Redemption Agreements such that the number of shares of Class A Common Stock to which each Anchor Investor may be entitled equals 11.111% of the number of Public Shares such Anchor Investor holds at the time the Business Combination is consummated (as opposed to when the Non-Redemption Agreement was signed). The Anchor Investors are not affiliated with or otherwise interested in DYNS or the Sponsor (except in respect of their ownership of Public Shares).

Separately, the Sponsor and DYNS’s other initial stockholders, which are affiliates of the Sponsor, in connection with and as partial consideration for DYNS proceeding with the Initial Public Offering, and for the covenants and commitments of DYNS set forth in a letter agreement with our Sponsor (the “IPO letter agreement”) (but, for the avoidance of doubt, for no other or additional consideration in connection with the Business Combination), have agreed to waive their redemption rights with respect to any Founder Shares, Private Placement Shares or Public Shares which they may hold, and the Sponsor has also agreed to waive its redemption rights with respect to any other equity securities it holds.

Q:	Do I have appraisal rights if I object to the proposed Business Combination?

A:	No. DYNS stockholders do not have appraisal rights in connection with the proposed Business Combination under Delaware law.

Q:	What happens if a substantial number of stockholders vote in favor of the Business Combination Proposal and exercise redemption rights?

Public Stockholders may vote in favor of the Business Combination and still exercise their redemption rights and are not required to vote in any way to exercise their redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the Trust Account and the number of Public Shares are substantially reduced as a result of redemptions by Public Stockholders (however, the condition to the consummation of the Business Combination requiring that DYNS have at least $5,000,001 of net tangible assets may not be waived). Also, with fewer Public Shares and Public Stockholders, the trading markets for Class A Common Stock following the Closing (which will be New Senti Common Stock) may be less liquid than the market for Class A Common Stock prior to the Business Combination, and New Senti may not be able to meet the listing standards of a national securities exchange, including Nasdaq. In addition, with fewer funds available from the Trust Account, the capital infusion from the Trust Account into New Senti’s business will be reduced and New Senti may not be able to achieve its business plans.

Q:	How do the Sponsor and the officers and directors of DYNS intend to vote on the Proposals?

The Sponsor, as well as DYNS’s officers and directors, beneficially own and are entitled to vote an aggregate of approximately 21.9% of the outstanding DYNS Common Stock as of the Record Date. These holders have agreed to vote their shares in favor of the Business Combination Proposal. These holders have also agreed to vote their shares in favor of all other Proposals being presented at the Special Meeting.

Q:	What do I need to do now?

DYNS urges you to carefully read and consider the information contained in this proxy statement/prospectus, including the Annexes, and to consider how the Business Combination will affect you as a stockholder of DYNS. DYNS stockholders should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy card.

Q:	How do I vote?

A:	If you are a holder of record of DYNS Common Stock on the Record Date, you may vote virtually at the Special Meeting or by submitting a proxy for the Special Meeting. You may submit your proxy by

xix

completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the meeting and vote in person (which would include presence at a virtual meeting), obtain a legal proxy from your broker, bank or nominee.

If you do not give instructions to your brokerage firm, the brokerage firm will not be allowed to vote your shares with respect to the Proposals. The Proposals are “non-discretionary” items. Your broker may not vote for non-discretionary items, and those votes will be counted as broker “non-votes.”

After obtaining a valid legal proxy from your broker, bank or nominee, to register to attend the Special Meeting, you must submit proof of your legal proxy reflecting the number of your shares along with your name and email address to Continental at proxy@continentalstock.com. Beneficial owners who e-mail a valid legal proxy will be issued a 12-digit meeting control number that will allow them to register to attend and participate in the Special Meeting. Beneficial owners who wish to attend the Special Meeting online should contact Continental no later than June 3, 2022 to obtain this information. Written requests can be emailed to proxy@continentalstock.com.

Q:	If my shares are held in “street name,” will my broker, bank or nominee automatically vote my shares for me?

A:	No. Your broker, bank or nominee cannot vote your shares unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank or nominee.

Q:	May I change my vote after I have mailed my signed proxy card?

Yes. DYNS stockholders may send a later-dated, signed proxy card to Continental at the address set forth above so that it is received prior to the vote at the Special Meeting or attend the Special Meeting virtually and vote. DYNS stockholders may also revoke their proxy by sending a notice of revocation to Continental, which must be received prior to the vote at the Special Meeting.

Q:	What happens if I fail to take any action with respect to the Special Meeting?

If you fail to take any action with respect to the Special Meeting and the Business Combination is approved by stockholders and consummated, you will continue to be a holder of Class A Common Stock (which will be New Senti Common Stock). As a corollary, failure to deliver (either physically or electronically) your stock certificate(s) to DYNS’s transfer agent, Continental, no later than two business days prior to the Special Meeting, means you will not have any right in connection with the Business Combination to exchange your Public Shares for a pro rata share of the funds held in the Trust Account. If you fail to take any action with respect to the Special Meeting and the Business Combination is not approved, you will continue to be a stockholder of DYNS.

Q:	What should I do with my share certificate(s)?

Those Public Stockholders who do not elect to have their Public Shares redeemed for a pro rata share of the funds held in the Trust Account need not submit their certificate(s). Public Stockholders who exercise their redemption rights must deliver their share certificate(s) to Continental (either physically or electronically) or through DTC to Continental at least two business days before the Special Meeting, as described above.

Q:	What should I do if I receive more than one set of voting materials?

A:	DYNS stockholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold

your DYNS shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold such shares. If you are a holder of record and your DYNS shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your DYNS shares.

Q:	Who can help answer my questions?

SUMMARY OF THE PROXY STATEMENT/PROSPECTUS

This summary highlights selected information from this proxy statement/prospectus and does not contain all of the information that is important to you. To better understand the Proposals to be submitted for a vote at the Special Meeting, including the Business Combination Proposal, you should read this entire document carefully, including the Annexes attached to this proxy statement/prospectus. The Business Combination Agreement is the primary legal document that governs the Business Combination and other transactions that will be undertaken in connection with the Business Combination. It is described in detail in this proxy statement/prospectus in the section entitled “Proposal 1: The Business Combination Proposal.”

The Parties

DYNS

Dynamics Special Purpose Corp. is a blank check company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. DYNS was incorporated under the laws of the State of Delaware on March 1, 2021.

On May 28, 2021, DYNS closed its Initial Public Offering of 23,000,000 shares of Class A Common Stock (the Public Shares). The shares of Class A Common Stock were sold at an offering price of $10.00 per share, generating gross proceeds of $230 million. The Initial Public Offering was conducted pursuant to a registration statement on Form S-1 (File No. 333-255930). Simultaneously with the consummation of the Initial Public Offering, DYNS consummated the Concurrent Private Placement of 715,500 shares of Class A Common Stock (the Private Placement Shares) at $10.00 per share, generating gross proceeds of $7,155,000. A total of $230 million, comprised of $225,400,000 of the net proceeds from the Initial Public Offering (which amount included $8,050,000 of the underwriter’s deferred underwriting fee (prior to such amount being reduced to $7,050,000, as described in this proxy statement/prospectus)) and $4,600,000, representing part of the proceeds of the sale of the Private Placement Shares, was deposited into the Trust Account, and the remaining proceeds, net of underwriting discounts and commissions and other costs and expenses, became available to be used by DYNS as working capital to provide for business, legal and accounting due diligence on prospective business combinations and continuing general and administrative expenses. As of the Record Date, there was $230,089,497.46 held in the Trust Account.

DYNS’s Class A Common Stock is listed on Nasdaq under the symbol “DYNS.”

The mailing address of DYNS’s principal executive office is 2875 El Camino Real, Redwood City, California 94061, and its telephone number is (408) 212-0200. After the consummation of the Business Combination, DYNS’s principal executive office will be that of Senti.

For additional information about DYNS, see the section entitled “Information about DYNS.”

Merger Sub

Merger Sub is a wholly-owned subsidiary of DYNS, formed solely for the purpose of effectuating the Business Combination described herein. Merger Sub was incorporated under the laws of the State of Delaware on December 14, 2021. Merger Sub owns no material assets and does not operate any business.

Senti

Senti Biosciences, Inc. is a preclinical biotechnology company developing next-generation cell and gene therapies engineered with its gene circuit platform technologies to fight challenging diseases. Senti’s mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, Senti has built a synthetic biology platform that it believes may enable it to program next-generation cell and gene therapies with what it refers to as “gene circuits.” These gene circuits, which Senti created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Senti aims to design and optimize gene circuits through its Design-Build-Test-Learn Engine, or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti is designing its gene circuit platform technologies to be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including hematopoietic stem cells (HSCs), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates currently utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful completion of IND-enabling studies, Senti expects to file INDs for multiple product candidates starting in 2023.

Senti was incorporated under the laws of the State of Delaware on June 9, 2016. The mailing address of Senti’s principal executive office is 2 Corporate Drive, First Floor, South San Francisco, California 94080, and its telephone number is (650) 382-3281.

For additional information about Senti, see the section entitled “Information about Senti.”

Going Concern

Senti has concluded that its recurring losses from operations and need for additional financing to fund future operations raise substantial doubt about its ability to continue as a going concern. Similarly, Senti’s independent registered public accounting firm included an explanatory paragraph in its report on Senti’s consolidated financial statements as of and for the year ended December 31, 2021 with respect to this uncertainty.

Emerging Growth Company

DYNS is an “emerging growth company,” as defined under the JOBS Act. As an emerging growth company, DYNS is eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. These include, but are not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and the requirement to obtain stockholder approval of any golden parachute payments not previously approved.

New Senti will remain an emerging growth company until the earlier of (1) December 31, 2026 (the last day of the fiscal year following the fifth anniversary of the consummation of the Initial Public Offering), (2) the last day of the fiscal year in which New Senti has total annual gross revenue of at least $1.07 billion, (3) the last day of the fiscal year in which New Senti is deemed to be a “large accelerated filer,” as defined in the Exchange Act, and (4) the date on which New Senti has issued more than $1.0 billion in nonconvertible debt securities during the prior three-year period.

The Business Combination Proposal

Pursuant to the Business Combination Agreement, a Business Combination between DYNS and Senti will be effected whereby Merger Sub will merge with and into Senti, with Senti surviving as a wholly-owned subsidiary of DYNS.

After consideration of the factors identified and discussed in the section entitled “Proposal 1: The Business Combination Proposal — The Board’s Reasons for Approval of the Business Combination,” our Board concluded that the Business Combination should be approved.

The terms and conditions of the Business Combination are contained in the Business Combination Agreement, which is attached to this proxy statement/prospectus as Annex A (or Annex AA in the case of Amendment No. 1 to Business Combination Agreement) and is incorporated by reference herein in its entirety. DYNS encourages you to read the Business Combination Agreement carefully, as it is the primary legal document that governs the Business Combination. For more information on the Business Combination Agreement, see the section entitled “Proposal 1: The Business Combination Proposal.”

Business Combination Consideration

Pursuant to the Business Combination Agreement:

•

Each outstanding share of Senti common stock held by the Sellers immediately before the Effective Time will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding share of Senti preferred stock held by the Sellers immediately before the Effective Time will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio (rounded down to the nearest whole share).

•

Each outstanding Senti option held immediately before the Effective Time will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option as at the time immediately before the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent).

Following the Closing, the Sellers may also be eligible to receive Contingency Consideration of up to an aggregate of 2,000,000 shares of Class A Common Stock (which would be shares of New Senti Common Stock) based on the share price of New Senti Common Stock following the Business Combination or, in certain circumstances, upon the occurrence of a change in control of New Senti. See the section titled “Proposal 1: The Business Combination Proposal — Structure of the Business Combination” for further information.

As of the Record Date, the Exchange Ratio was approximately 0.1955 (the calculation of which is described on page 169 of this proxy statement/prospectus). Based on this Exchange Ratio, the total number of shares of Class A Common Stock expected to be issued at the Closing (not including shares that will be issuable upon exercise of outstanding stock options following the Closing) is approximately 23,112,889 shares, and these shares are expected to represent between approximately 39.0% and 52.3% of the issued and outstanding shares of Class A Common Stock (which will be New Senti Common Stock) immediately following the closing of the PIPE Investment and the Business Combination, assuming, at the low end of that range, no redemptions from our Trust Account occur, and, at the high end of that range, maximum redemptions from our Trust Account occur, and assuming that no shares of Class A Common Stock subject to Non-Redemption Agreements as at the date of this proxy statement/prospectus are redeemed. Please see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” for further information regarding what constitutes a “maximum redemption” scenario.

The Board’s Reasons for Approval of the Business Combination

The Board considered a wide variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the Board, as a whole, did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the Board may have given different weight to different factors.

For a more complete description of the Board’s reasons for the approval of the Business Combination and its recommendation in favor of the Business Combination Proposal, please see the section entitled “Proposal 1: The Business Combination — The Board’s Reasons for Approval of the Business Combination.”

Accounting Treatment

Notwithstanding the legal form, the Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. generally accepted accounting principles (“GAAP”). Under this method of accounting, DYNS will be treated as the acquired company for financial reporting purposes, whereas Senti will be treated as the accounting acquiror. In accordance with this accounting method, the Business Combination will be treated as the equivalent of Senti issuing stock for the net assets of DYNS, accompanied by a recapitalization. The net assets of Senti will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Business Combination will be those of Senti. Senti has been determined to be the accounting acquiror for purposes of the Business Combination based on an evaluation of the following facts and circumstances:

•

if the Director Election Proposal is approved by DYNS stockholders, persons affiliated with Senti will control a majority of the governing body of New Senti;

•

Senti’s operations prior to the Business Combination will comprise the ongoing operations of New Senti; and

•

Senti’s existing senior management team will comprise the senior management team of the Combined Company.

Pro Forma Ownership of New Senti Upon Closing

Immediately after the Closing, assuming no Public Stockholder exercises its redemption rights and no additional shares are issued prior to Closing, the Sellers will own approximately 39.0% of the shares of New Senti Common Stock to be outstanding immediately after the Business Combination, Public Stockholders will own approximately 40.3% of the shares of New Senti Common Stock, the Sponsor will own approximately 9.4% of the shares of New Senti Common Stock and the PIPE Investors will own approximately 11.3% of the shares of New Senti Common Stock, in each case, based on the number of shares of Class A Common Stock and Class B Common Stock outstanding as of the Record Date. These pro forma ownership percentages also (a) assume no exercise of any options to purchase Class A Common Stock (which will be New Senti Common Stock) that will be outstanding immediately following the Business Combination, whether such options are issued under the Incentive Plan or otherwise, (b) exclude the issuance of any shares in connection with the Incentive Plan and the ESPP following the Business Combination, (c) exclude the Contingency Consideration, if any, and (d) assume that 885,377 Founder Shares are forfeited by the Sponsor and cancelled, with the Anchor Investors concurrently being issued an equivalent number of shares of Class A Common Stock in connection with the Non-Redemption Agreements. If the actual facts are different from the assumptions stated above, then the levels of ownership interest set forth above will be different. For more information, please see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information.”

Additional Matters Being Voted On By DYNS Stockholders

In addition to voting on the Business Combination Proposal, DYNS stockholders will vote on the following Proposals.

The Charter Amendment Proposal

Assuming the Business Combination Proposal is approved and adopted, DYNS stockholders will vote on a proposal to approve the Proposed Charter, which will amend and restate the Current Charter, and amended bylaws for the Combined Company. If approved, the Proposed Charter and amended bylaws will be in effect upon the Closing. See the section entitled “Proposal 2: The Charter Amendment Proposal” for further information. A copy of the Proposed Charter and the amended bylaws is attached to this proxy statement/prospectus as Annex B.

The Advisory Charter Amendment Proposals

On a non-binding advisory basis, DYNS stockholders will vote on a proposal to approve the Advisory Charter Amendment Proposals, which are being presented pursuant to guidance of the SEC as seven separate sub-proposals. See the section entitled “Proposal 3: The Advisory Charter Amendment Proposals” for further information.

The Nasdaq Stock Issuance Proposal

Assuming the Business Combination Proposal is approved and adopted, for purposes of complying with the applicable provisions of Nasdaq Listing Rule 5635, DYNS stockholders will vote on (a) the issuance of up to 26,000,000 shares of Class A Common Stock in connection with the Business Combination, and (b) the issuance of an aggregate of 6,680,000 shares of Class A Common Stock in connection with the PIPE Investment concurrent with the Closing. See the section entitled “Proposal 4: The Nasdaq Stock Issuance Proposal” for further information.

The Director Election Proposal

Assuming the Business Combination Proposal is approved and adopted, holders of Class B Common Stock will vote on a proposal to approve of the appointment of seven directors who, upon consummation of the Business Combination, will become the directors of the Combined Company. See the section entitled “Proposal 5: The Director Election Proposal” for further information.

The Incentive Plan Proposal

Assuming the Business Combination Proposal is approved and adopted, DYNS stockholders will vote on a proposal to approve the Incentive Plan, which will become effective as of and contingent on the consummation of the Business Combination. See the section entitled “Proposal 6: The Incentive Plan Proposal” for further information.

The ESPP Proposal

Assuming the Business Combination Proposal is approved and adopted, DYNS stockholders will vote on a proposal to approve the ESPP, which will become effective as of and contingent on the consummation of the Business Combination. See the section entitled “Proposal 7: The ESPP Proposal” for further information.

The Adjournment Proposal

DYNS stockholders will be asked to consider and vote upon a proposal to adjourn the Special Meeting to a later date or dates if it is determined that more time is necessary or appropriate, in the judgment of the Board or the officer presiding over the Special Meeting, for DYNS to consummate the Business Combination (including to solicit additional votes in favor of any of the Proposals). See the section entitled “Proposal 8: The Adjournment Proposal” for further information.

DYNS’s Sponsor and Officers and Directors

As of the Record Date, the Sponsor and DYNS’s officers and directors beneficially owned and were entitled to vote an aggregate of 6,465,500 shares of DYNS Common Stock. The shares owned by the Sponsor and DYNS’s officers and directors currently constitute approximately 21.9% of the outstanding DYNS Common Stock.

In connection with the Initial Public Offering, the Sponsor and each of DYNS’s officers and directors agreed to vote their Founder Shares, Private Placement Shares and any Public Shares they hold in favor of an initial business combination (including any proposals recommended by the Board in connection with such business combination). This commitment would extend to include the Business Combination Proposal and the other Proposals.

In connection with the Initial Public Offering, the Sponsor and the directors and officers of DYNS entered into a lock-up agreement pursuant to which they agreed not to transfer the Founder Shares (subject to limited exceptions) until one year after the consummation of an initial business combination or earlier if, subsequent to the consummation of an initial business combination, (i) the last sale price of Class A Common Stock (which would be New Senti Common Stock) equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 trading day period commencing at least 150 days after the initial business combination, or (ii) New Senti consummates a subsequent liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of its Public Stockholders having the right to exchange their shares of Class A Common Stock (which would be New Senti Common Stock) for cash, securities or other property. Additionally, the holders of Private Placement Shares purchased in the Concurrent Private Placement agreed not to transfer such shares (subject to limited exceptions) until 30 days after the consummation of an initial business combination (together with the lock-up described in the preceding sentence, the “Existing Sponsor Lock-ups”).

In connection with DYNS’s entry into the Business Combination Agreement, pursuant to the sponsor support agreement, a copy of which is exhibited to the Business Combination Agreement (the “Sponsor Support Agreement”), and effective as of the consummation of the Closing, the Existing Sponsor Lock-ups will be replaced with the lock-up arrangements described in the Investor Rights Agreement further described in the section entitled “Proposal 1: The Business Combination Agreement – Related Agreements – Investor Rights Agreement.”

Special Meeting Information

Date, Time and Place of Special Meeting

The Special Meeting will be held virtually on June 7, 2022, at 10:00 AM, Eastern Time, at https://www.cstproxy.com/dspc/2022. DYNS stockholders may attend, vote and examine the list of DYNS stockholders entitled to vote at the Special Meeting by visiting https://www.cstproxy.com/dspc/2022 and entering the control number found on their proxy card, voting instruction form or notice they previously received. In light of public health concerns regarding the coronavirus (COVID-19), the Special Meeting will be held in a virtual meeting format only. You will not be able to attend the Special Meeting physically.

Voting Power; Record Date

DYNS stockholders will be entitled to vote or direct votes to be cast at the Special Meeting if they owned DYNS Common Stock at the close of business on May 3, 2022, which is the Record Date for the Special Meeting. Stockholders will have one vote for each share of DYNS Common Stock owned at the close of business on the Record Date in respect of each Proposal on which they are entitled to vote. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 29,465,500 shares of DYNS Common Stock entitled to vote at the Special Meeting, of which 6,465,500 were owned by the Sponsor or an affiliate thereof.

Quorum and Vote of DYNS Stockholders

A quorum of DYNS stockholders is necessary to hold a valid meeting. A quorum will be present at the Special Meeting if a majority of the voting power of all outstanding shares of DYNS Common Stock entitled to vote at the meeting are represented in person (which would include presence at a virtual meeting) or by proxy. As of the Record Date, there were 23,715,500 shares of Class A Common Stock and 5,750,000 shares of Class B Common Stock outstanding; therefore, a total of 14,732,751 shares of DYNS Common Stock must be represented at the Special Meeting in order to constitute a quorum. Abstentions and withheld votes will count as present for the purposes of establishing a quorum, but will not count as votes cast at the Special Meeting for any of the Proposals. Because the Proposals are “non-discretionary” items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker “non-vote” will be deemed to have occurred for each of the Proposals. Broker “non-votes” will not be counted as present for purposes of determining whether a quorum is present. As of the Record Date, the Sponsor holds approximately 21.9% of the outstanding DYNS Common Stock.

The Proposals presented at the Special Meeting will require the following votes:

•

The approval of the Charter Amendment Proposal will require the affirmative vote of the holders of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately, as well as the vote of the holders of a majority of the issued and outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class. Accordingly, a DYNS stockholder’s failure to vote by proxy or in person (which would include presence at a virtual meeting) at the Special Meeting or an abstention will have the same effect as a vote “AGAINST” the Charter Amendment Proposal.

•

The approval of each of the Nasdaq Stock Issuance Proposal, the Incentive Plan Proposal, the ESPP Proposal, the Adjournment Proposal and each of the Advisory Charter Amendment Proposals will require the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting as a single class.

•

The Director Election Proposal will require a plurality vote of the shares of Class B Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting. “Plurality” means that the individuals who receive the largest number of votes cast “FOR” are elected as directors. Consequently, any shares not voted “FOR” a particular nominee (whether as a result of an abstention, a direction to withhold authority or a broker non-vote) will not be counted in the nominee’s favor.

Abstentions, withheld votes and broker non-votes will have no effect on any of the Proposals that will be presented at the Special Meeting, aside from those effects set forth above.

Consummation of the Business Combination is conditioned on approval of the Business Combination Proposal, the Charter Amendment Proposal, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal and the ESPP Proposal (and each such Proposal is cross-conditioned on the approval of such other Proposals). If any of these Proposals is not approved, the other Proposals will not be presented to stockholders for a vote.

Redemption Rights of DYNS Stockholders

Pursuant to the Current Charter, any holders of Public Shares may demand that such shares be redeemed in exchange for a pro rata share of the aggregate amount on deposit in the Trust Account, including interest earned on the funds in the Trust Account but less franchise and income taxes payable and less the reimbursement prior to Closing of up to $163,889 in franchise taxes paid by DYNS in 2022 (provided that such reimbursement shall not reduce the Trust Account balance below $230,000,000). If demand is properly made and the Business Combination is consummated, those Public Shares will, at the Closing, cease to be outstanding and will represent only the right to receive a pro rata share of the aggregate amount then on deposit in the Trust Account. For illustrative purposes, based on funds in the Trust Account of $230,089,497.46 on the Record Date, the estimated per share redemption price would have been approximately $10.00.

In order to exercise your redemption rights, you must:

•

provide, in the written request to redeem your Public Shares for cash to Continental, DYNS’s transfer agent, a “Stockholder Certification” if you are not acting in concert or as a “group” (as defined in Section 13 of the Exchange Act) with any other stockholder with respect to shares of DYNS Common Stock; and

•

prior to June 3, 2022 (two business days before the Special Meeting), tender your shares physically or electronically and submit a request in writing that DYNS redeem your Public Shares for cash to Continental at the following address:

Continental Stock Transfer & Trust Company

One State Street Plaza, 30^th Floor

New York, New York 10004

Attn: Mark Zimkind

E-mail: mzimkind@continentalstock.com; or

deliver your Public Shares, either physically or electronically through DTC to Continental, at least two business days before the Special Meeting. Public Stockholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from Continental and time to effect delivery. It is DYNS’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from Continental. However, DYNS does not have any control over this process and it may take longer than two weeks. Stockholders who hold their Public Shares in “street” name will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically. If you do not submit a written request and deliver your Public Shares as described above, your shares will not be redeemed.

Any request for redemption, once made by a Public Stockholder, may be withdrawn at any time prior to the time the vote is taken with respect to the Business Combination Proposal at the Special Meeting. If you deliver your Public Shares for redemption directly to Continental or deliver your Public Shares either physically or electronically through DTC to Continental, and later decide prior to the Special Meeting not to elect redemption, you may request that Continental return the shares (physically or electronically). You may make such request by contacting Continental at (917) 262-2373, by email at proxy@continentalstock.com or by writing to the address listed above.

Prior to exercising redemption rights, Public Stockholders should verify the market price of shares of Class A Common Stock as they may receive higher proceeds from the sale of their shares of Class A Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. We cannot assure you that you will be able to sell your shares of Class A Common Stock in the open market, even if the market price per share is higher than the estimated redemption price stated above, as there may not be sufficient liquidity in Class A Common Stock when you wish to sell your shares.

If you exercise your redemption rights, your shares of Class A Common Stock will cease to be outstanding at the Closing and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account, as described above. You will no longer own those shares and will have no right to participate in, or have any interest in, the future growth of the Combined Company, if any. You will be entitled to receive cash for your Public Shares only if you properly and timely demand redemption, in accordance with the process described above.

If the Business Combination is not approved or completed for any reason, then Public Stockholders who elected to exercise their redemption rights will not be entitled to redeem their shares. In such case, DYNS will promptly return any Public Shares previously delivered by the Public Stockholders.

Underwriting Fees as a Percentage of Initial Public Offering Proceeds Net of Redemptions


	No redemptions⁽²⁾			Maximum redemptions⁽³⁾
IPO underwriting fees⁽¹⁾	$	11,650,000		$	11,650,000

IPO proceeds net of redemptions	$	230,000,000		$	81,093,370

Underwriting fees as a % of IPO proceeds net of redemptions (approx.)		5.1	%		14.4	%

(1)	IPO underwriting fees expected to comprise (a) $4,600,000, which was paid at the time our Initial Public Offering was consummated, and (b) $7,050,000 of deferred underwriting fees (this amount having being reduced from $8,050,000 by $1,000,000 by agreement with J.P. Morgan on December 17, 2021).

(2)	This scenario assumes that no Public Shares are redeemed.

(3)

As at the date of this proxy statement/prospectus, there are 23,000,000 Public Shares issued and outstanding and, as at April 29, 2022, 7,968,483 of these Public Shares are subject to Non-Redemption Agreements. This scenario assumes that all 15,031,517 Public Shares that are not subject to Non-Redemption Agreements as at April 29, 2022 are redeemed, resulting in an aggregate payment of $150,315,170 out of the Trust Account (based on an assumed redemption price of $10.00 per share).

Tax Consequences of Business Combination

For a description of the material U.S. federal income tax consequences of the Business Combination, please see the information set forth in the section entitled “Material U.S. Federal Income Tax Considerations.”

Appraisal Rights

DYNS stockholders do not have appraisal rights in connection with the Business Combination under Delaware law.

Regulatory Matters

Under the HSR Act and the rules that have been promulgated thereunder by the U.S. Federal Trade Commission (“FTC”), certain transactions may not be consummated unless information has been furnished to the

Antitrust Division of the Department of Justice (“Antitrust Division”) and the FTC and certain waiting period requirements have been satisfied. The Business Combination is subject to these requirements and may not be completed until the expiration of a 30-day waiting period following the filing of the required Notification and Report Forms with the Antitrust Division and the FTC or until early termination is granted. On January 10, 2022, DYNS and Senti filed their respective HSR Act Notification and Report Forms with the Antitrust Division and the FTC. Consequently, the required waiting period expired at 11:59 PM, Eastern Time, on February 9, 2022.

At any time before or after consummation of the Business Combination, notwithstanding expiration or termination of the waiting period under the HSR Act, the applicable competition authorities in the United States or any other applicable jurisdiction could take such action under applicable antitrust laws as such authority deems necessary or desirable in the public interest, including seeking to enjoin the consummation of the Business Combination, conditionally approving the Business Combination upon divestiture of certain of New Senti’s assets, subjecting the completion of the Business Combination to regulatory conditions or seeking other remedies. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. DYNS cannot assure you that the Antitrust Division, the FTC, any state attorney general or any other government authority, or any private party, will not attempt to challenge the Business Combination on antitrust grounds, and, if such a challenge is made, DYNS cannot assure you as to its result. Under the Business Combination Agreement, DYNS and Senti are not obligated to sell, license or otherwise dispose of any entities, assets or facilities (or agree to do so), or terminate, assign or amend any existing relationships or contractual rights or obligations, or enter into new licenses or other contracts in order to obtain approval of the Business Combination by the FTC, the Antitrust Division or otherwise.

Neither DYNS nor Senti is aware of any material regulatory approvals or actions that are required for completion of the Business Combination other than the expiration of the waiting period under the HSR Act, which period has expired. It is presently contemplated that if any such additional regulatory approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions which are required will be obtained.

Proxy Solicitation

Proxies may be solicited by mail, telephone or in person (which would include presence at a virtual meeting). DYNS has engaged Morrow Sodali to assist in the solicitation of proxies. If a stockholder grants a proxy, they may still vote their shares in person (which would include presence at a virtual meeting) if they revoke their proxy before the Special Meeting. A stockholder may also change their vote by submitting a later-dated proxy as described in the section entitled “Special Meeting of DYNS Stockholders — Revoking Your Proxy.”

Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination

In considering the recommendation of the Board to vote in favor of approval of the Business Combination Proposal, the Charter Amendment Proposal and the other Proposals, DYNS stockholders should keep in mind that the Sponsor (which is affiliated with certain of DYNS’s officers and directors) and DYNS’s officers and directors have interests in such Proposals that are different from, or in addition to, your interests as a DYNS stockholder. These interests include, among other things:

•

If the Business Combination with Senti or another business combination is not consummated by May 28, 2023 (or such later date as may be approved by DYNS’s stockholders), DYNS will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and its Board, dissolving and liquidating. In such event, (i) the 5,750,000 Founder Shares held by the Sponsor, which were acquired by the Sponsor for a purchase price of approximately $0.004 per share, or $25,000 in the aggregate, prior to the Initial Public Offering, and (ii) the 715,500 Private Placement Shares purchased by the

Sponsor for a purchase price of $10.00 per share, or $7,155,000 in the aggregate, in the Concurrent Private Placement, would be worthless because the holders are not entitled to participate in any redemption or distribution from the Trust Account with respect to such securities. Such securities had an aggregate market value of approximately $64.3 million based upon the closing price of $9.94 per share of Class A Common Stock on Nasdaq on the Record Date.

•

The fact that, given the differential between the purchase price that the Sponsor paid for the Founder Shares (which will convert to shares of Class A Common Stock in connection with the Business Combination) and the price of the Public Shares sold in the Initial Public Offering, the Sponsor may earn a positive rate of return on its investment even if the Class A Common Stock (or New Senti Common Stock) trades below the price paid by Public Stockholders for Public Shares in the Initial Public Offering (and, consequently, the Public Stockholders experience a negative rate of return following the completion of the Business Combination). Specifically, the Sponsor (and DYNS’s officers and directors who are members of the Sponsor, or whose affiliates are members of the Sponsor) has invested an aggregate of $7,180,000 in DYNS securities, comprising the $25,000 purchase price for 5,750,000 Founder Shares (which, upon consummation of the Business Combination, is currently expected to be reduced to 4,864,623 Founder Shares upon the forfeiture by the Sponsor of 885,377 Founder Shares in connection with the Non-Redemption Agreements) and the $7,155,000 purchase price for 715,500 Private Placement Shares. Assuming a trading price of $9.94 per share of New Senti Common Stock immediately following the Closing (based upon the closing price of $9.94 per share for Class A Common Stock on Nasdaq on the Record Date), these 4,864,623 Founder Shares and 715,500 Private Placement Shares have an implied aggregate market value of approximately $55.5 million immediately following the Closing. Even if the trading price for shares of New Senti Common Stock following the Business Combination was as low as approximately $1.29 per share, the aggregate market value of the Founder Shares and Private Placement Shares (which would be shares of New Senti Common Stock) would be approximately equal to the initial investment in DYNS by the Sponsor (and DYNS’s officers and directors who are members of the Sponsor, or whose affiliates are members of the Sponsor). As a result, the Sponsor (and DYNS’s officers and directors who are members of the Sponsor, or whose affiliates are members of the Sponsor) are likely to be able to make a substantial profit on their investment in DYNS even at a time when shares of New Senti Common Stock have lost significant value. On the other hand, and as noted in the bullet above, if DYNS does not complete a business combination by May 28, 2023 and liquidates, the Sponsor (and DYNS’s officers and directors who are members of the Sponsor, or whose affiliates are members of the Sponsor) will likely lose their entire investment in DYNS. These financial interests may mean that the Sponsor (and DYNS’s officers and directors who are members of the Sponsor, or whose affiliates are members of the Sponsor) may be incentivized to complete the Business Combination, or an alternative business combination, with a less favorable target company or on terms less favorable to stockholders than they would otherwise recommend or approve, as the case may be, rather than allow DYNS to wind up having failed to consummate a business combination and lose their entire investment.

•

If DYNS is unable to complete a business combination within the required time period, the Sponsor will be personally liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by DYNS for services rendered or contracted for or products sold to DYNS. If, on the other hand, DYNS consummates a business combination, DYNS will be liable for all such claims.

•

The Business Combination Agreement provides for the continued indemnification of DYNS’s current directors and officers and the continuation of directors’ and officers’ liability insurance covering DYNS’s current directors and officers from and after the Effective Time for a period of six (6) years.

•

The fact that two of DYNS’s current directors and officers are expected to be directors of New Senti and, as such, may in the future receive cash fees, stock options, stock awards or other remuneration that the New Senti Board determines to pay to them.

•

None of DYNS’s officers or directors will be required to commit his or her full time to the affairs of New Senti and, accordingly, may have conflicts of interest in allocating his or her time among various business activities.

•

In the course of their other business activities, DYNS’s officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to New Senti as well as the other entities with which they are affiliated. DYNS’s officers and directors may have conflicts of interest in determining to which entity a particular business opportunity should be presented.

•

The Sponsor and DYNS’s other initial stockholders have agreed to waive their redemption rights with respect to any shares of DYNS Common Stock they may hold in connection with the Business Combination. Additionally, our initial stockholders have agreed to waive any right, title, interest or claim regarding any monies held in the Trust Account, or any other asset of DYNS, in respect of the Founder Shares and Private Placement Shares, as a result of any liquidation of DYNS (including if we fail to consummate our initial business combination within 24 months after the closing of the Initial Public Offering). If DYNS does not complete an initial business combination within such applicable time period, the proceeds of the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares, and the Private Placement Shares purchased in the Concurrent Private Placement will expire worthless. The Private Placement Shares purchased in the Concurrent Private Placement held by DYNS’s initial stockholders had an aggregate market value of approximately $7.1 million based upon the closing price of $9.94 per share of Class A Common Stock on Nasdaq on the Record Date. In addition, effective as of the Closing, with certain limited exceptions, the lock-up arrangements described in the Investor Rights Agreement will prevent the transfer or assignment of Class A Common Stock (or any securities convertible into or exercisable or exchangeable for shares of Class A Common Stock, which will be New Senti Common Stock) in accordance with the terms thereof. These lock-up arrangements are further described in the section entitled “Proposal 1: The Business Combination Agreement – Related Agreements – Investor Rights Agreement.” Since the Sponsor and DYNS’s officers and directors have direct or indirect interests in DYNS Common Stock, DYNS’s officers and directors may have a conflict of interest in determining whether a particular target business (including Senti) is an appropriate business with which to effectuate our initial business combination.

•

DYNS’s officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors was included by a target business as a condition to, or was the result of, any agreement with respect to the initial business combination, as is the case for the proposed Business Combination with Senti.

•

The Sponsor and DYNS’s officers or directors may have a conflict of interest with respect to evaluating a business combination and financing arrangements as DYNS may obtain loans from the Sponsor or an affiliate of the Sponsor or any of DYNS’s officers or directors to finance transaction costs in connection with an intended initial business combination. As of the date of this proxy statement/prospectus, no such loans are outstanding.

•

The Sponsor and DYNS’s officers and directors may have incurred reimbursable expenses that may not be reimbursed or repaid if the Business Combination Proposal is not approved. Such interests may have influenced their decision to approve and, in the case of the Board, recommend, the Business Combination with Senti. As of the date of filing of this proxy statement/prospectus, no reimbursable expenses are outstanding.

•

The Sponsor, certain stockholders of DYNS, and certain stockholders of Senti will be party to the Investor Rights Agreement, which will come into effect at the Effective Time. See the section entitled “Proposal 1: The Business Combination Agreement – Related Agreements – Investor Rights Agreement” for a summary of the key terms of this agreement.

Recommendation to DYNS Stockholders

After careful consideration, the Board determined unanimously that each of the Business Combination Proposal, the Charter Amendment Proposal, the Advisory Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal, if presented, is fair to and in the best interests of DYNS and its stockholders. The Board has approved and declared advisable and unanimously recommends that you vote or give instructions to vote “FOR” each of these Proposals.

For a description of various factors considered by the Board in reaching its decision to recommend in favor of voting for each of the Proposals to be presented at the Special Meeting, see the sections herein regarding each of the Proposals. In particular, in respect of the Board’s unanimous determination that the Business Combination Proposal is fair to and in the best interests of DYNS and its stockholders, and its recommendation that DYNS stockholders vote or give instructions to vote “FOR” such Proposal, you should carefully review the substantive factors considered by DYNS’s management team and the Board in coming to such determination and in making such recommendation, as set forth in the section of this proxy statement/prospectus entitled “Proposal 1: The Business Combination Proposal – The Board’s Reasons for Approval of the Business Combination.”

Summary of Risk Factors

The following is a summary of the principal risks to which (i) Senti’s business, operations and financial performance and (ii) the Business Combination are subject. Each of these risks is more fully described in the individual risk factors set forth under “Risk Factors” in this proxy statement/prospectus. Unless the context otherwise requires, all references in this subsection to the “Company,” “we,” “us” or “our” refer to the business of Senti prior to the consummation of the Business Combination, which will be the business of the Combined Company following the consummation of the Business Combination.

Risks Related to the Business, Operations and Financial Performance of Senti

•

We are a preclinical stage biotechnology company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

•

We will need substantial additional funds to advance development of product candidates and our gene circuit platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates and technologies.

•

We have identified a material weakness in our internal control over financial reporting. If our remediation of the material weakness is not effective, or if we experience additional material weaknesses or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

•

Our history of recurring losses and anticipated expenditures raises substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern requires that we obtain sufficient funding to finance our operations.

•

If any of our current or potential future product candidates is ever tested in humans, it may not demonstrate the safety, purity and potency, or efficacy, necessary to become approvable or commercially viable.

•

Our gene circuit platform technologies are based on novel technologies that are unproven and may not result in approvable or marketable products, which exposes us to unforeseen risks and makes it difficult for us to predict the time and cost of product development and potential for regulatory approval.

•

Although we intend to explore other therapeutic opportunities in addition to the product candidates we are currently pursuing, we may fail to identify viable new product candidates for clinical development, which could materially harm our business.

•

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

•

We rely on third parties to conduct our preclinical studies, and plan to rely on third parties to conduct clinical trials, and those third parties may not perform satisfactorily. If third parties on which we intend to rely to conduct certain preclinical and clinical studies do not perform as contractually required, fail to satisfy regulatory or legal requirements or miss expected deadlines, our development program could be delayed or unsuccessful, and we may not be able to obtain regulatory approval for or commercialize our product candidates when expected, or at all.

•

We may not be able to maintain our existing strategic partnerships and collaboration arrangements or enter into new strategic partnerships and collaborations for the development, manufacture and commercialization of product candidates based on our platform technology on terms that are acceptable to us, or at all.

•

The manufacturing of our product candidates is complex. We may encounter difficulties in production. If we encounter any such difficulties, our ability to supply our product candidates for clinical trials or, if approved, for commercial sale, could be delayed or halted entirely.

•

We face competition from companies that have developed or may develop product candidates for the treatment of the diseases that we may target, including companies developing novel therapies and platform technologies. If these companies develop platform technologies or product candidates more rapidly than we do, or if their platform technologies or product candidates are more effective or have fewer side effects, our ability to develop and successfully commercialize product candidates may be adversely affected.

•

Our future success depends on our ability to retain key employees, directors, consultants and advisors and to attract, retain and motivate qualified personnel.

•

We may experience difficulties in managing our growth and expanding our operations. We have limited experience in therapeutic development. As our current and potential future product candidates enter and advance through preclinical studies and any clinical trials, we will need to expand our development, regulatory and manufacturing capabilities or contract with other organizations to provide these capabilities for us.

•

Our business, operations and clinical development plans and timelines could be adversely affected by the ongoing COVID-19 pandemic, including business interruptions, staffing shortages and supply chain issues arising from the pandemic on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom we may conduct business, including our anticipated contract manufacturers, contract research organizations (“CROs”), suppliers, shippers and others.

•

If we are unable to obtain or protect intellectual property rights related to our technology and current or future product candidates, or if our intellectual property rights are inadequate, our competitors could develop and commercialize products and technology similar or identical to ours, and we may not be able to compete effectively in our market or successfully commercialize any product candidates we may develop.

•

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our current or potential future product candidates.

•

Even if we are able to commercialize any product candidate, such product candidate may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies, which would harm our business.

•

We or the third parties upon whom we depend may be adversely affected by natural disasters, including earthquake, flood, fire, explosion, extreme weather conditions, or medical epidemics.

Risks Related to the Business Combination and Redemptions

•

DYNS will not have any right after the Closing to make damage claims against Senti or Senti’s stockholders for the breach of any representation, warranty or covenant made by Senti in the Business Combination Agreement.

•

Subsequent to the Closing, New Senti may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and stock price, which could cause you to lose some or all of your investment.

•

The Sponsor and DYNS’s officers and directors own DYNS Common Stock that will be worthless and may incur reimbursable expenses that may not be reimbursed or repaid if the Business Combination is not approved. Such interests may have influenced their decision to approve and, in the case of the Board, recommend, the Business Combination with Senti.

•

The exercise of DYNS’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination or waivers of conditions are appropriate and in the best interests of DYNS’s stockholders.

•

If DYNS is unable to complete the Business Combination with Senti or another business combination by May 28, 2023 (or such later date as may be approved by DYNS’s stockholders), DYNS will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and its Board, dissolving and liquidating. In such event, third parties may bring claims against DYNS and, as a result, the proceeds held in the Trust Account could be reduced and the per-share liquidation price received by stockholders could be less than $10.00 per Public Share.

•

Neither the Board nor any committee thereof obtained a third-party financial opinion in determining whether or not to pursue the Business Combination.

•

There is no guarantee that a Public Stockholder’s decision to continue to hold shares of Class A Common Stock following the Business Combination will put the stockholder in a better future economic position than if they decided to redeem their Public Shares for a pro rata portion of the Trust Account, and vice versa.

•

The consummation of the Business Combination is conditioned on, among other things, there being at least $150,000,000 in cash available at Closing. DYNS has entered into Non-Redemption Agreements with the Anchor Investors to assist with satisfying this condition, however, the Anchor Investors’ commitments not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary exchange-traded fund (“ETF”) or mutual fund pro rata rebalancing transfers. Despite the Non-Redemption Agreements, there is no guarantee that there will be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. If Senti did waive the condition in these circumstances, it is possible that New Senti would have insufficient capital to conduct and grow its business after Closing in the manner described in this proxy statement/prospectus.

•

The listing of New Senti’s securities on Nasdaq will not benefit from the process undertaken in connection with an underwritten initial public offering.

•

Redemptions of Public Shares by Public Stockholders may affect the market price of New Senti Common Stock.

Legal proceedings in connection with the Business Combination

On March 8, 2022, in connection with the proposed Business Combination, a purported shareholder of DYNS sent a demand letter to DYNS’s and Senti’s counsel, alleging that the registration statement on Form S-4 filed with the SEC by DYNS on February 14, 2022 omitted material information with respect to the proposed Business Combination, and demanding that DYNS and the Board immediately make certain supplemental corrective disclosures to address the alleged deficiencies. DYNS believes that the claims described in the demand letter are without merit.

Comparison of Governance and Stockholders’ Rights

Following the Closing, the rights of DYNS stockholders who remain New Senti stockholders will no longer be governed by the Current Charter and DYNS’s duly adopted bylaws and will instead be governed by the Proposed Charter and the new bylaws (as amended from time to time) adopted in connection with the Charter Amendment Proposal. See “Comparison of Governance and Stockholders’ Rights” for further information.

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following selected unaudited pro forma condensed combined financial data is derived from the unaudited pro forma condensed combined balance sheet and unaudited pro forma condensed combined statements of operations included elsewhere in this proxy statement/prospectus and is provided to aid you in your

analysis of the financial aspects of the Business Combination, Non-Redemption Agreements and the consummation of the PIPE Investment, which are collectively referred to as the “Transactions.”

The unaudited pro forma condensed combined financial statements are based on the DYNS historical financial statements and the Senti historical consolidated financial statements as adjusted to give effect to the Transactions. The unaudited pro forma condensed combined balance sheet gives pro forma effect to the Transactions as if they had been consummated on December 31, 2021. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2021 gives effect to the Transactions as if they had occurred on January 1, 2021.

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X, as amended by the final rule, Release No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses. Release No. 33-10786 replaced the previous pro forma adjustment criteria with simplified requirements to depict the accounting for the Transactions (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Management has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the combined company reflecting the Transactions.

The unaudited pro forma condensed combined financial statements are provided for illustrative purposes only and are not necessarily indicative of what the actual results of operations and financial position would have been had the Transactions taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the combined company.

The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with:

•

the accompanying notes to the unaudited pro forma condensed combined financial statements included elsewhere in this proxy statement/prospectus;

•

the historical audited financial statements of DYNS as of December 31, 2021 and for the period from March 1, 2021 (inception) through December 31, 2021 and the related notes included elsewhere in this proxy statement/prospectus;

•

the historical audited consolidated financial statements of Senti as of and for the year ended December 31, 2021 and the related notes included elsewhere in this proxy statement/prospectus; and

•

the sections entitled “DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Senti Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and other financial information relating to DYNS and Senti included elsewhere in this proxy statement/prospectus.

The selected unaudited pro forma condensed combined financial data below presents two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1): This presentation assumes that no Public Stockholders exercise their right to redeem their Public Shares for their pro rata share of the Trust Account, and thus, the full amount held in the Trust Account as of the Closing is available for the Business Combination; and

•

Assuming Maximum Redemptions (Scenario 2): This presentation assumes that 15,031,517 Public Shares are redeemed, resulting in an aggregate cash payment of approximately $150.3 million out of the Trust Account based on an assumed redemption price of $10.00 per share. This redemption figure is derived by subtracting the 7,968,483 shares that will not be redeemed by Anchor Investors (due to Non-Redemption Agreements) from the 23,000,000 Public Shares issued and outstanding as at the Record Date. After a redemption of approximately $150.3 million out of the $230.0 million Trust Account, and the $66.8 million PIPE Investment, the available cash at Closing would be approximately $146.5 million, which would be just under the condition in the Business Combination Agreement that there be at least $150.0 million in available Closing cash. As this condition is for Senti’s benefit, this Scenario assumes Senti will waive it prior to Closing, however there is no guarantee that it would and, if it did not, the Business Combination would not be consummated. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the Non- Redemption Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 15,031,517 Public Shares could be redeemed and that there may be less than approximately $146.5 million in cash available at Closing. The redemption of more than 15,031,517 Public Shares would change some of the figures presented in the maximum redemption scenario in the unaudited pro forma financial data.

DYNS cautions you that the foregoing list may not contain all of the forward-looking statements made in this proxy statement/prospectus.

These forward-looking statements are only predictions based on the current expectations and projections of DYNS and Senti about future events and are subject to a number of risks, uncertainties and assumptions, including those described in “Risk Factors” and elsewhere in this proxy statement/prospectus. Moreover, Senti operates in a competitive industry, and new risks emerge from time to time. It is not possible for the management of DYNS or Senti to predict all risks, nor can DYNS or Senti assess the impact of all factors on their respective businesses or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements DYNS may make in this proxy statement/prospectus. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this proxy statement/prospectus may not occur, and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements in this proxy statement/prospectus.

The forward-looking statements included in this proxy statement/prospectus are made only as of the date hereof. You should not rely upon forward-looking statements as predictions of future events. Although DYNS believes that the expectations reflected in its forward-looking statements are reasonable, neither DYNS nor Senti can guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Neither DYNS nor Senti undertakes any obligation to update publicly any forward-looking statements for any reason after the date of this proxy statement/prospectus to conform these statements to actual results or to changes in expectations, except as required by law.

You should read this proxy statement/prospectus and the documents that have been filed as Annexes and exhibits hereto with the understanding that the actual future results, levels of activity, performance, events and circumstances of DYNS and Senti may be materially different from what is expected.

RISK FACTORS

Stockholders should consider and read carefully all of the risks and uncertainties described below, as well as other information included in this proxy statement/prospectus, before they decide whether to vote or instruct their vote to be cast to approve the Proposals described in this proxy statement/prospectus. The value of your investment in New Senti following consummation of the Business Combination will be subject to the significant risks affecting New Senti and inherent to the industry in which it will operate. If any of the events described below occur, the post-acquisition business and financial results could be adversely affected in a material way. This could cause the trading price of the Combined Company’s common stock to decline, perhaps significantly, and you therefore may lose all or part of your investment. Unless the context otherwise requires, all references in this subsection to the “Company,” “we,” “us” or “our” refer to the business of Senti prior to the consummation of the Business Combination, which will be the business of the Combined Company following the consummation of the Business Combination.

Summary of Risk Factors

The following is a summary of principal risk to which (i) our business, operations and financial performance and (ii) the Business Combination and redemptions are subject. Each of these risks is more fully described in the individual risk factors immediately following this summary:

Risks Related to the Business, Operations and Financial Performance of Senti

•

We will need substantial additional funds to advance development of our product candidates and our gene circuit platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates and technologies.

•

Our current product candidates are in preclinical development and have never been tested in humans. One or all of our current product candidates may fail in clinical development or suffer delays that materially and adversely affect their commercial viability.

•

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

•

Our future success depends on our ability to retain key employees, directors, consultants and advisors and to attract, retain and motivate qualified personnel.

•

Our business, operations and clinical development plans and timelines could be adversely affected by the ongoing COVID-19 pandemic, including business interruptions, staffing shortages and supply chain issues arising from the pandemic, on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom we may conduct business, including our anticipated contract manufacturers, CROs, suppliers, shippers and others.

•

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our current or potential future product candidates.

•

We or the third parties upon whom we depend may be adversely affected by other natural disasters, including earthquake, flood, fire, explosion, extreme weather conditions, or medical epidemics.

Risks Related to the Business Combination and Redemptions

•

The exercise of DYNS’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination Agreement or waivers of conditions are appropriate and in the best interests of DYNS’s stockholders.

•

Neither the Board nor any committee thereof obtained a third-party financial opinion in determining whether or not to pursue the Business Combination.

•

There is no guarantee that a Public Stockholder’s decision whether to continue to hold shares of Class A Common Stock following the Business Combination will put the stockholder in a better future economic position than if they decided to redeem their Public Shares for a pro rata portion of the Trust Account, and vice versa.

•

The consummation of the Business Combination is conditioned on, among other things, there being at least $150,000,000 in cash available at Closing. DYNS has entered into Non-Redemption Agreements with the Anchor Investors to assist with satisfying this condition, however, the Anchor Investors’ commitments not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. Despite the Non-Redemption Agreements, there is not guarantee that there will be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. If Senti did waive the condition in these circumstances, it is possible that New Senti would have insufficient capital to conduct and grow its business after Closing in the manner described in this proxy statement/prospectus.

•

The listing of New Senti’s securities on Nasdaq will not benefit from the process undertaken in connection with an underwritten initial public offering.

•

Redemptions of Public Shares by Public Stockholders may affect the market price of New Senti Common Stock.

Risks Related to Senti’s Limited Operating History and Financial Condition

We are a preclinical stage biotechnology company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability.

We are a preclinical stage biotechnology company with a history of losses. Since our inception, we have devoted substantially all of our resources to research and development, preclinical studies, building our management team and building our intellectual property portfolio, and we have incurred significant operating losses. Our net losses were $55.3 million and $19.9 million for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, we had an accumulated deficit of $115.1 million. Substantially all of our

losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. To date, we have not generated any revenue from product sales, and we have not sought or obtained regulatory approval for any product candidate. Furthermore, we do not expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies, clinical trials, manufacturing and the regulatory approval process for our current and potential future product candidates.

We expect our net losses to increase substantially as we:

•

continue to advance our gene circuit platform technologies;

•

continue preclinical development of our current and future product candidates and initiate additional preclinical studies;

•

commence clinical trials of our current and future product candidates;

•

establish our manufacturing capability, including developing our contract development and manufacturing organization relationships and building our internal manufacturing facilities;

•

acquire and license technologies aligned with our gene circuit platform technologies;

•

seek regulatory approval of our current and future product candidates;

•

expand our operational, financial, and management systems and increase personnel, including personnel to support our preclinical and clinical development, manufacturing and commercialization efforts;

•

continue to develop, perfect, and defend our intellectual property portfolio; and

•

incur additional legal, accounting, or other expenses in operating our business, including the additional costs associated with operating as a public company.

However, the amount of our future losses is uncertain. Our ability to achieve or sustain profitability, if ever, will depend on, among other things, successfully developing product candidates, obtaining regulatory approvals to market and commercialize product candidates, manufacturing any approved products on commercially reasonable terms, entering into potential future alliances, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we, or our potential future collaborators, are unable to commercialize one or more of our product candidates, or if sales revenue from any product candidate that receives approval is insufficient, we will not achieve or sustain profitability, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Even if we consummate the Business Combination, we will need substantial additional funds to advance development of product candidates and our gene circuit platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates and technologies.

The development of biotechnology product candidates is capital-intensive. If any of our current or potential future product candidates enter and advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. We have used substantial funds to develop our gene circuit platform, SENTI-202, SENTI-301, SENTI-401 and other product candidates, and we will require significant funds to continue to develop our platform and conduct further research and development, including preclinical studies and clinical trials. In addition, upon the closing of the Business Combination, we expect to incur significant additional costs associated with operating as a public company.

As of December 31, 2021, we had $56.0 million in cash and cash equivalents. Our future capital requirements and the period for which our existing resources will support our operations may vary significantly from what we expect. Our monthly spending levels vary based on new and ongoing research and development and other corporate activities. Because the length of time and activities associated with successful research and development of platform technologies and product candidates is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. The timing and amount of our operating expenditures will depend largely on:

•

the timing and progress of preclinical and clinical development of our current and potential future product candidates;

•

the timing and progress of our development of our gene circuit platforms;

•

the number and scope of preclinical and clinical programs we decide to pursue;

•

the costs of building and operating our own dedicated Current Good Manufacturing Practice (“cGMP”) and Current Good Tissue Practice (“cGTP”) facility to support clinical and commercial-scale production of multiple allogeneic natural killer (NK) cell product candidates, and the terms of any third-party manufacturing contract or biomanufacturing partnership we may enter into;

•

our ability to maintain our current licenses and collaborations, conduct our research and development programs and establish new strategic partnerships and collaborations;

•

the progress of the development efforts of our existing strategic partners and third parties with whom we may in the future enter into collaboration and research and development agreements;

•

the costs involved in obtaining, maintaining, enforcing and defending patents and other intellectual property rights;

•

the impact of the COVID-19 pandemic on our business;

•

the cost and timing of regulatory approvals; and

•

our efforts to enhance operational systems and hire additional personnel, including personnel to support development of our product candidates and satisfy our obligations as a public company.

To date, we have primarily financed our operations through the sale of equity securities. We may seek to raise any necessary additional capital through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements, grants and other marketing and distribution arrangements. We cannot assure you that we will be successful in acquiring additional funding at levels sufficient to fund our operations or on terms favorable to us. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our preclinical studies, clinical trials, research and development programs or commercialization efforts. Because of the numerous risks and uncertainties associated with the development and commercialization of our current and potential future product candidates and the extent to which we may enter into collaborations with third parties to participate in their development and commercialization, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated preclinical studies and clinical trials, including related manufacturing costs. To the extent that we raise additional capital through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our current and potential future product candidates, future revenue streams or research programs or grant licenses on terms that may not be favorable to us. If we do raise additional capital through public or private equity or convertible debt offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

We do not expect to realize revenue from product sales or royalties from licensed products for the foreseeable future, if at all, and unless and until our current and potential future product candidates are clinically tested, approved for commercialization and successfully marketed.

We have identified a material weakness in our internal control over financial reporting. If our remediation of the material weakness is not effective, or if we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of New Senti Common Stock.

Prior to the closing of the Business Combination, we have been a private company with limited accounting personnel and other resources with which to address our internal control over financial reporting. In connection with our preparation and the audit of our consolidated financial statements as of and for the year ended December 31, 2021, we and our independent registered public accounting firm identified a material weakness, as defined under the Exchange Act and by the Public Company Accounting Oversight Board (United States), in our internal control over financial reporting. The material weakness related to a lack of sufficient and adequate resources in the finance and accounting function that resulted in a lack of formalized risk assessment process, lack of segregation of duties, and ineffective process level control activities over the management review of journal entries, account reconciliations and non-routine transactions. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our consolidated financial statements will not be prevented or detected on a timely basis.

We are in the process of implementing a risk assessment process and measures designed to improve our internal control over financial reporting and remediate the control deficiencies that led to the material weakness, including hiring additional accounting personnel. The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. For example, to maintain and improve the effectiveness of our financial reporting, we will need to commit significant resources, implement and strengthen existing disclosure processes, train personnel and provide additional management oversight.

We cannot be certain that the measures we have taken to date, and actions we may take in the future, will be sufficient to remediate the control deficiencies that led to our material weakness in our internal control over financial reporting or that they will prevent or avoid potential future material weaknesses. In addition, neither our management nor an independent registered public accounting firm has performed an evaluation of our internal control over financial reporting because no such evaluation has been previously required. The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing and remediation. Testing internal controls may divert our management’s attention from other matters that are important to our business.

Pursuant to Section 404 of the Sarbanes-Oxley Act (“Section 404”), our management will be required to report upon the effectiveness of our internal control over financial reporting beginning with the annual report for our fiscal year ending December 31, 2022. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may issue a report that is qualified if it is not satisfied with our controls or the level at which our controls are documented, designed, operated or reviewed. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing, and possible remediation. To comply with the requirements of being a reporting company under the Exchange Act, we will need to implement additional financial and management controls, reporting systems, procedures, and hire additional accounting and finance staff.

When we lose our status as an “emerging growth company” and become an “accelerated filer” or a “large accelerated filer,” our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404. Accordingly, you may not be able to depend on any attestation concerning our internal control over financial reporting from our independent registered public accountants for the foreseeable future.

Our testing, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. A material

weakness in internal controls could result in our failure to detect a material misstatement of our annual or quarterly consolidated financial statements or disclosures. We may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404. If we are unable to conclude that we have effective internal controls over financial reporting, investors could lose confidence in our reported financial information, which could have a material adverse effect on the trading price of New Senti Common Stock.

We cannot be certain as to the timing of completion of our evaluation, testing and any remediation actions or the impact of the same on our operations. If we are unable to successfully remediate our existing or any future material weaknesses in our internal control over financial reporting, or identify any additional material weaknesses, the accuracy and timing of our financial reporting may be negatively impacted, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. If we are not able to implement the requirements of Section 404 in a timely manner or with adequate compliance, our independent registered public accounting firm may issue an adverse opinion due to ineffective internal controls over financial reporting, and we may be subject to sanctions or investigation by regulatory authorities, such as the SEC. As a result, there could be a negative reaction in the financial markets due to a loss of confidence in the reliability of our consolidated financial statements. In addition, we may be required to incur costs in improving our internal control system and the hiring of additional personnel. Any such action could negatively affect our results of operations and cash flows.

Members of our management team have limited experience in managing the day-to-day operations of a public company and, as a result, we may incur additional expenses associated with the management of our company.

Members of our management team have limited experience in managing the day-to-day operations of a public company. As a result, we may need to obtain outside assistance from legal, accounting, investor relations, or other professionals that could be more costly than planned. We also plan to hire additional personnel to comply with additional SEC reporting requirements. These compliance costs will make some activities significantly more time-consuming and costly. If we lack cash resources to cover these costs in the future, our failure to comply with reporting requirements and other provisions of securities laws could negatively affect our stock price and adversely affect our potential results of operations, cash flow and financial condition.

We have incurred significant operating losses to date, and it is possible we may never generate a profit. Our consolidated financial statements included elsewhere in this proxy statement/prospectus have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. These consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of these uncertainties related to our ability to operate on a going concern basis.

We have concluded that our recurring losses from operations and need for additional financing to fund future operations raise substantial doubt about our ability to continue as a going concern. Similarly, our independent registered public accounting firm included an explanatory paragraph in its report on our consolidated financial statements as of and for the year ended December 31, 2021 with respect to this uncertainty. We believe that the $64.7 million of gross proceeds raised in May 2021 from the sale of our Series B preferred, coupled with successful completion of the Business Combination, will eliminate this doubt and enable us to continue as a going concern; however, we may need to obtain alternative financing or significantly modify our operational plans for us to continue as a going concern. Based upon our current operating plan and assumptions, we believe that our existing cash and cash equivalents, including the results of the Business Combination, will be sufficient to fund our operations for at least the next 12 months. This estimate is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect.

Changes may occur beyond our control that would cause us to consume our available capital before that time, including changes in and progress of our development activities and changes in regulation. Our future capital requirements will depend on many factors, including:

•

the scope, rate of progress, results and costs of platform development activities, preclinical studies, laboratory testing and clinical trials for our product candidates;

•

the number and development requirements of product candidates that we may pursue, and other indications for our current product candidates that we may pursue;

•

the costs, timing and outcome of regulatory review of our product candidates;

•

the scope and costs of constructing and operating our planned cGMP and cGTP facility and any commercial manufacturing activities;

•

the cost associated with commercializing any approved product candidates;

•

the cost and timing of developing our ability to establish sales and marketing capabilities, if any;

•

the cost and timing of maintaining and expanding the applications of our gene circuit platform technology;

•

the costs of preparing, filing and prosecuting patent applications, maintaining, enforcing and protecting our intellectual property rights, defending intellectual property-related claims and obtaining licenses to third-party intellectual property;

•

the timing and amount of any milestone and royalty payments we are required to make under our present or future license agreements;

•

our ability to establish and maintain strategic partnerships and collaborations, including any biomanufacturing partnerships or collaborations involving the use of our platform technology, on favorable terms, if at all; and

•

the extent to which we acquire or in-license other product candidates and technologies and associated intellectual property.

We will require additional capital to complete our planned clinical development programs for our current product candidates to obtain regulatory approval. Any additional capital raising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our current and future product candidates, if approved.

In addition, we cannot guarantee that future financing will be available on a timely basis, in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities by us, whether equity or debt, or the market perception that such issuances are likely to occur, could cause the market price of New Senti Common Stock to decline. If we are unable to raise sufficient capital when needed, our business, financial condition and results of operations will be harmed, and we will need to significantly modify our operational plans to continue as a going concern. If we are unable to continue as a going concern, we might have to liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements.

Our ability to use net operating loss carryforwards (“ NOLs”) and credits to offset future taxable income may be subject to certain limitations.

Our NOLs could expire unused and be unavailable to offset future income tax liabilities because of their limited duration or because of restrictions under U.S. tax law. NOLs generated in taxable years beginning before January 1, 2018 are permitted to be carried forward for 20 taxable years under applicable U.S. federal income tax

law. Under the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), as modified by the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”), NOLs arising in tax years beginning after December 31, 2020 may not be carried back. Moreover, under the Tax Act as modified by the CARES Act, NOLs generated in taxable years beginning after December 31, 2017 may be carried forward indefinitely, but the deductibility of such NOLs generally will be limited in taxable years beginning after December 31, 2020 to 80% of current year taxable income. As of December 31, 2021, we had NOLs for federal and state income tax purposes of approximately $145.1 million, a portion of which expire beginning in 2031 if not utilized. NOLs generated in 2021 for federal tax reporting purposes of approximately $35.5 million have an indefinite life.

In general, under Section 382 of the Code, a corporation that undergoes an “ownership change” (defined under Section 382 of the Code and applicable Treasury Regulations as a greater than 50 percentage point change (by value) in a corporation’s equity ownership by certain stockholders over a rolling three-year period) is subject to limitations on its ability to utilize its pre-change NOLs to offset future taxable income. We have not determined whether our NOLs are limited under Section 382 of the Code. We may have experienced ownership changes in the past and may experience ownership changes in the future, including as a result of the Business Combination or subsequent shifts in our stock ownership (some of which are outside our control). Furthermore, our ability to utilize NOLs of companies that we may acquire in the future may be subject to limitations. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs or other unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to reduce future income tax liabilities, including for state tax purposes. For these reasons, we may not be able to utilize a material portion of the NOLs reflected on our balance sheet, even if we attain profitability, which could potentially result in increased future tax liability to us and could adversely affect our operating results and financial condition.

Risks Related to the Development and Clinical Testing of Our Product Candidates

We have no products on the market or that have gained regulatory approval or that have entered clinical trials. None of our product candidates has ever been tested in humans. Our ability to achieve and sustain profitability depends on obtaining regulatory approvals for and successfully commercializing product candidates, either alone or with collaborators.

Before obtaining regulatory approval for the commercial distribution of our product candidates, we or a collaborator must conduct extensive preclinical studies, followed by clinical trials to demonstrate the safety, purity and potency, or efficacy of our product candidates in humans. There is no guarantee that the U.S. Food and Drug Administration (the “FDA”) will permit us to conduct clinical trials. Further, we cannot be certain of the timely completion or outcome of our preclinical studies and cannot predict if the FDA or other regulatory authorities will accept our proposed clinical programs, our clinical protocols or if the outcome of our preclinical studies will ultimately support the further development of our preclinical programs or testing in humans. As a result, we cannot be sure that we will be able to submit IND or similar applications for our proposed clinical programs on the timelines we expect, if at all, and we cannot be sure that submission of INDs or similar applications will result in the FDA or other regulatory authorities allowing clinical trials for any of our product candidates to begin.

Our current product candidates are in preclinical development and we are subject to the risks of failure inherent in the development of product candidates based on novel approaches, targets and mechanisms of action. Although we anticipate initiating clinical trials for our lead product candidates, there is no guarantee that we will be able to proceed with clinical development of any of these product candidates or that any product candidate will demonstrate a clinical benefit once we advance these candidates to testing in patients. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by preclinical stage biotechnology companies such as ours.

We may not be able to access the financial resources to continue development of, or to enter into any collaborations for, any of our current or potential future product candidates. This may be exacerbated if we experience any issues that delay or prevent regulatory approval of, or our ability to commercialize, a product candidate, such as:

•

negative or inconclusive results from our preclinical studies or clinical trials or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;

•

product-related side effects experienced by participants in our clinical trials or by individuals using therapeutics similar to our product candidates;

•

delays in submitting INDs or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulatory authorities to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;

•

conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;

•

delays in enrolling research subjects in clinical trials;

•

high drop-out rates of research subjects;

•

inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

•

chemistry, manufacturing and control (“CMC”) challenges associated with manufacturing and scaling up biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;

•

greater-than-anticipated clinical trial costs;

•

poor potency or effectiveness of our product candidates during clinical trials;

•

unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;

•

delays as a result of the COVID-19 pandemic or events associated with the pandemic;

•

failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;

•

delays and changes in regulatory requirements, policies and guidelines; or

•

the FDA or other regulatory authorities interpreting our data differently than we do.

Further, we and any existing or potential future collaborator may never receive approval to market and commercialize any product candidate. Even if we or any existing or potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or an existing or potential future collaborator may also be subject to post-marketing testing requirements to maintain regulatory approval.

None of our current product candidates have ever been tested in humans. We may ultimately discover that our current product candidates do not possess certain properties that we believe are helpful for therapeutic effectiveness and safety or would otherwise support the submission of an IND on the timelines we expect, or at all. We do not know if the observations we have made regarding our gene circuits generally and our product

candidates in particular will translate into any clinical response when tested in humans. As an example, while the Tumor-Associated Antigen (“TAA”) CD33 has been clinically validated as a target for an approved antibody-drug conjugate therapy, it has not been clinically validated as a target for CAR-NK or CAR-T therapies, and may not prove to be a clinically sufficient target for the CAR-NK therapies we are developing. As a result of these uncertainties related to our gene circuit platform technologies and our product candidates, we may never succeed in developing a marketable product based on our current product candidates. If any of our current or potential future product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We are seeking to identify and develop a broad pipeline of product candidates using our gene circuit platform technologies. The scientific research that forms the basis of our efforts to develop product candidates with our platforms is still ongoing. We are not aware of any FDA approved therapeutics utilizing similar technologies as ours. Further, the scientific evidence to support the feasibility of developing therapeutic treatments based on our platform technologies is preliminary. As a result, we are exposed to a number of unforeseen risks and it is difficult to predict the types of challenges and risks that we may encounter during development of our product candidates. For example, we have not tested any of our current product candidates in humans, and our current data is limited to animal models and preclinical cell lines, the results of which may not translate into humans. Further, relevant animal models and assays may not accurately predict the safety and efficacy of our product candidates in humans, and we may encounter significant challenges creating appropriate models and assays for demonstrating the safety and efficacy of our product candidates. In addition, our gene circuit technologies have potential safety risks. For example, if the NOT GATE gene circuit, as described below, engineered into one of our product candidates, such as SENTI-202, does not provide a clinically sufficient level of inhibition, it may kill healthy cells that it has been designed to preserve or may cause systemic immune cytotoxicity. As another example, if the small-molecular regulator dial does not achieve a clinically sufficient level of control over IL-12 secretion, either leaky IL-12 production in the uninduced state or overproduction of IL-12 in the induced state may result in systemic immune toxicity. It is possible that safety events or concerns such as these or others could negatively affect the development of our product candidates, including adversely affecting patient enrollment among the patient populations that we intend to treat.

Given the novelty of our technologies, we intend to work closely with the FDA and comparable foreign regulatory authorities to evaluate our proposed approaches to obtain regulatory approval for our product candidates; however, due to a lack of comparable experiences, the regulatory pathway with the FDA and comparable regulatory authorities may be more complex and time-consuming relative to other more well-known therapeutics. Even if we obtain human data to support our product candidates, the FDA or comparable foreign regulatory agencies may lack experience in evaluating the safety and efficacy of our product candidates developed using our platforms, which could result in a longer than expected regulatory review process, increase our expected development costs, and delay or prevent commercialization of our product candidates. The validation process takes time and resources, may require independent third-party analyses, and may not be accepted or approved by the FDA and comparable foreign regulatory authorities. We cannot be certain that our approach will lead to the development of approvable or marketable products, alone or in combination with other therapies.

We may not be successful in our efforts to use and expand our gene circuit platform to expand our pipeline of product candidates.

A key element of our strategy is to use and advance our gene circuit platform to design, test and build our portfolio of product candidates focused on allogeneic gene circuit-equipped CAR-NK cell therapies for the treatment of cancer. Although our research and development efforts to date have resulted in our discovery and

preclinical development of SENTI-202, SENTI-301, SENTI-401 and other potential product candidates, none of these product candidates has advanced to clinical development. We cannot assure you that any of our existing product candidates will advance to clinical trials or, if they do, that such trials will demonstrate these product candidates to be safe or effective therapeutics, and we may not be able to successfully develop any product candidates. Even if we are successful in expanding our pipeline of product candidates, any additional product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future.

Although we intend to explore other therapeutic opportunities in addition to the product candidates that we are currently developing, we may fail to identify viable new product candidates for clinical development for a number of reasons. If we fail to identify additional potential product candidates, our business could be materially harmed.

Although a substantial amount of our efforts will focus on the planned clinical trials and potential approval of the current and potential future product candidates we are evaluating, a key element of our strategy is to discover, develop, manufacture and globally commercialize additional targeted therapies beyond our current product candidates to treat various conditions and in a variety of therapeutic areas. Even if we identify investigational therapies that initially show promise, we may fail to successfully develop and commercialize such products for many reasons, including the following:

•

the research methodology used may not be successful in identifying potential investigational therapies;

•

competitors may develop alternatives that render our investigational therapies obsolete;

•

investigational therapies we develop may nevertheless be covered by third parties’ patents or other exclusive rights;

•

an investigational therapy may, on further study, be shown to have harmful side effects or other characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory criteria;

•

it may take greater human and financial resources than we will possess to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research programs, thereby limiting our ability to develop, diversify and expand our product portfolio;

•

an investigational therapy may not be capable of being produced in clinical or commercial quantities at an acceptable cost, or at all; and

•

an approved product may not be accepted as safe and effective by trial participants, the medical community or third-party payors.

Identifying new investigational therapies requires substantial technical, financial and human resources, whether or not any investigational therapies are ultimately identified. Because we have limited financial and human resources, we may initially focus on research programs and product candidates for a limited set of indications. As a result, we may forgo or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. For example, if we do not accurately evaluate the commercial potential or target market for a particular product candidate or technology, we may relinquish valuable rights to that product candidate or technology through collaborations, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate or technology.

Accordingly, there can be no assurance that we will ever be able to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research programs, which could materially adversely affect our future growth and prospects. We may focus our efforts and resources on potential product candidates or other potential programs that ultimately prove to be unsuccessful.

The market, physicians, patients, regulators and potential investors, may not be receptive to our current or potential future product candidates and may be skeptical of the viability and benefits of our gene circuit pipeline technology because it is based on a relatively novel and complex technology.

The market, physicians, patients, regulators and potential investors, may be skeptical of the viability and benefits of our gene circuit pipeline technology or our product candidates because they are based on a relatively novel and complex technology and there can be no assurance that our product candidates or platform technologies will be understood, approved, or accepted. If potential investors are skeptical of the success of our pipeline products, our ability to raise capital and the value of our stock may be adversely affected. If physicians, patients, or regulators do not understand or accept our gene circuit platform technologies or our product candidates, we may be delayed in or unable to develop our product candidates.

Even if regulatory approval is obtained for a product candidate, including SENTI-202, SENTI-301 and SENTI-401, we may not generate or sustain revenue from sales of approved products. Market acceptance of our gene circuit platform technologies and our current and potential future product candidates, if approved, will depend on, among other factors:

•

the timing of our receipt of any marketing and commercialization approvals;

•

the terms of any approvals and the countries in which approvals are obtained;

•

the safety and efficacy of our product candidates and gene circuit technologies in general;

•

the prevalence and severity of any adverse side effects associated with our product candidates;

•

limitations or warnings contained in any labeling approved by the FDA or other regulatory authority;

•

relative convenience and ease of administration of our product candidates;

•

the success of our physician education programs;

•

the availability of coverage and adequate government and third-party payor reimbursement;

•

the pricing of our products, particularly as compared to alternative treatments; and

•

availability of alternative effective treatments for the disease indications our product candidates are intended to treat and the relative risks, benefits and costs of those treatments.

If any product candidate we commercialize fails to achieve market acceptance, it could have a material adverse effect on our business, financial condition, results of operations and prospects.

The occurrence of serious complications or side effects in connection with use of our product candidates, either in clinical trials or post-approval, could lead to discontinuation of our clinical development programs, refusal of regulatory authorities to approve our product candidates or, post-approval, revocation of marketing authorizations or refusal to approve applications for new indications, which could severely harm our business, prospects, operating results and financial condition.

Undesirable side effects caused by any of our current or potential future product candidates could cause regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. While we have not yet initiated clinical trials for SENTI-202, SENTI-301, SENTI-401 or any other product candidate, it is likely that there will be side effects associated with their use. Results of our clinical trials could reveal a high and unacceptable

severity and prevalence of these side effects. For example, if the NOT GATE gene circuit engineered into one of our product candidates, such as SENTI-202, does not provide a clinically sufficient level of inhibition, it may kill healthy cells that it has been designed to preserve or may cause systemic immune cytotoxicity. As another example, if the small-molecular regulator dial does not achieve a clinically sufficient level of control over IL-12 secretion, either leaky IL-12 production in the uninduced state or overproduction of IL-12 in the induced state may result in systemic immune toxicity. It is possible that safety events or concerns such as these or others could negatively affect the development of our product candidates, including adversely affecting patient enrollment among the patient populations that we intend to treat. In such an event, our trials could be suspended or terminated, and the FDA or other regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. Such side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. To date, we have not observed any such effects in our preclinical studies, but there can be no guarantee that our current or future product candidates will not cause such effects in clinical trials. Any of these occurrences may materially and adversely affect our business and financial condition and impair our ability to generate revenues.

Further, clinical trials by their nature utilize a sample of the potential patient population. With a limited number of patients and limited duration of exposure, rare and severe side effects of a product candidate may only be uncovered when a significantly larger number of patients are exposed to the product candidate or when patients are exposed for a longer period of time.

In the event that any of our current or potential future product candidates receives regulatory approval and we or others identify undesirable side effects caused by one of these products, any of the following events could occur, which could result in the loss of significant revenue to us and materially and adversely affect our results of operations and business:

•

regulatory authorities may withdraw their approval of the product or seize the product;

•

we may be required to recall the product or change the way the product is administered to patients;

•

additional restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component thereof;

•

we may be subject to fines, injunctions or the imposition of civil or criminal penalties;

•

regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;

•

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

•

we could be sued and held liable for harm caused to patients;

•

the product may become less competitive; and

•

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, results of operations and prospects.

While we believe our pipeline will yield multiple INDs, we may not be able to file INDs to commence clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed.

We expect our pipeline to yield multiple INDs beginning as early as 2023, including INDs for SENTI-202 and SENTI-301. We cannot be sure that submission of an IND will result in the FDA allowing testing and clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such clinical trials. The manufacturing of our product candidates, including SENTI-202, SENTI-301 and SENTI-401, remains an emerging and evolving field. Accordingly, we expect chemistry, manufacturing and control related topics, including product specifications, will be a focus of IND reviews, which may delay the clearance of INDs.

Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND or clinical trial application, we cannot guarantee that such regulatory authorities will not change their requirements in the future.

In addition to the submission of an IND to the FDA before initiation of a clinical trial in the United States, certain human clinical trials involving recombinant or synthetic nucleic acid molecules are subject to oversight of institutional biosafety committees (“IBCs”), as set forth in the National Institutes of Health (“NIH”) Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules (“NIH Guidelines”). Under the NIH Guidelines, recombinant and synthetic nucleic acids are defined as: (i) molecules that are constructed by joining nucleic acid molecules and that can replicate in a living cell (i.e., recombinant nucleic acids); (ii) nucleic acid molecules that are chemically or by other means synthesized or amplified, including those that are chemically or otherwise modified but can base pair with naturally occurring nucleic acid molecules (i.e., synthetic nucleic acids); or (iii) molecules that result from the replication of those described in (i) or (ii). Specifically, under the NIH Guidelines, supervision of human gene transfer trials includes evaluation and assessment by an IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment, and such review may result in some delay before initiation of a clinical trial. While the NIH Guidelines are not mandatory unless the research in question is being conducted at or sponsored by institutions receiving NIH funding of recombinant or synthetic nucleic acid molecule research, many companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them.

Interim, topline and preliminary data that we announce or publish from time to time for any clinical trials that we initiate may change as more patient data become available or as additional analyses are conducted, and as the data are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose interim, preliminary or topline data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, preliminary or topline results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the final data are available. From time to time, we may also disclose interim, preliminary or topline data from our clinical studies. Interim, topline or preliminary data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between preliminary, topline or interim data and final data could significantly harm our business prospects.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and the value of our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product candidate or our business. If the topline data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

We and our collaborators may not achieve projected discovery and development milestones and other anticipated key events in the time frames that we or they announce, which could have an adverse impact on our business and could cause our stock price to decline.

From time to time, we expect that we will make public statements regarding the expected timing of certain milestones and key events, such as the commencement and completion of preclinical and IND-enabling studies in our product candidate discovery programs with collaborators as well as the commencement and completion of planned clinical trials in those programs. The actual timing of these events can vary dramatically due to a number of factors such as delays or failures in our or any future collaborators’ product candidate discovery and development programs, the amount of time, effort and resources committed by us and any future collaborators, and the numerous uncertainties inherent in the development of therapies. As a result, there can be no assurance that our or any future collaborators’ programs will advance or be completed in the time frames we or they announce or expect. If we or any collaborators fail to achieve one or more of these milestones or other key events as planned, our business could be materially adversely affected, and the price of our common stock could decline.

Clinical trials are expensive, time-consuming and difficult to design and implement.

Human clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. Because our current and potential future product candidates are based on new technologies and discovery approaches, we expect that they will require extensive research and development and have substantial manufacturing and processing costs. In addition, the FDA or other regulatory authorities may require us to perform additional testing before commencing clinical trials and be hesitant to allow us to enroll patients impacted with our targeted disease indications in our future clinical trials. If we are unable to enroll patients impacted by our targeted disease indications in our future clinical trials, we would be delayed in obtaining potential proof-of-concept data in humans, which could extend our development timelines. In addition, costs to treat patients and to treat potential side effects that may result from our product candidates may be significant. Accordingly, our clinical trial costs are likely to be high and could have a material adverse effect on our business, financial condition, results of operations and prospects.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

We may not be able to initiate or continue any clinical trials for our current or potential future product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or other regulatory authorities. We cannot predict how difficult it will be to enroll patients for trials in the indications we are studying. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The enrollment of patients depends on many factors, including:

•

the severity of the disease under investigation;

•

the patient eligibility criteria defined in the clinical trial protocol;

•

the size of the patient population required for analysis of the trial’s primary endpoints;

•

the proximity and availability of clinical trial sites for prospective patients;

•

willingness of physicians to refer their patients to our clinical trials;

•

our ability to recruit clinical trial investigators with the appropriate competencies and experience;

•

clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating;

•

our ability to obtain and maintain patient consents;

•

the risk that patients enrolled in clinical trials will drop out of the trials before completion; and

•

factors we may not be able to control, such as current or potential pandemics, including the ongoing COVID-19 pandemic, that may limit the availability of patients, principal investigators or staff or clinical sites to participate in our clinical trials.

In addition, our future clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. Additionally, because some of our clinical trials will be in patients with advanced disease who may experience disease progression or adverse events independent from our product candidates, such patients may be unevaluable for purposes of the trial and, as a result, we may require additional enrollment. Delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates.

If clinical trials for our product candidates are prolonged, delayed or stopped, we may be unable to seek or obtain regulatory approval and commercialize our product candidates on a timely basis, or at all, which would require us to incur additional costs and delay our receipt of any product revenue.

We may experience delays in our ongoing or future preclinical studies or clinical trials, and we do not know whether future preclinical studies or clinical trials will begin on time, need to be redesigned, enroll an adequate number of patients on time or be completed on schedule, if at all. The commencement or completion of these clinical trials could be substantially delayed or prevented by many factors, including:

•

further discussions with the FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials, including the endpoint measures required for regulatory approval and our statistical plan;

•

the limited number of, and competition for, suitable study sites and investigators to conduct our clinical trials, many of which may already be engaged in other clinical trial programs with similar patients, including some that may be for the same indications as our product candidates;

•

any delay or failure to obtain timely approval or agreement to commence a clinical trial in any of the countries where enrollment is planned;

•

inability to obtain sufficient funds required for a clinical trial;

•

clinical holds on, or other regulatory objections to, a new or ongoing clinical trial;

•

delay or failure to manufacture sufficient quantities or inability to produce quantities of consistent quality, purity and potency of the product candidate for our clinical trials;

•

delay or failure to reach agreement on acceptable clinical trial agreement terms or clinical trial protocols with prospective sites or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different sites or CROs;

•

delay or failure to obtain institutional review board (“IRB”) or ethics committee approval to conduct a clinical trial at a prospective site;

•

the FDA or other comparable foreign regulatory authorities may require us to submit additional data or impose other requirements before permitting us to initiate a clinical trial;

•

slower than expected rates of patient recruitment and enrollment;

•

failure of patients to complete the clinical trial;

•

the inability to enroll a sufficient number of patients in studies to ensure adequate statistical power to detect statistically significant treatment effects;

•

unforeseen safety issues, including severe or unexpected drug-related adverse effects experienced by patients, including possible deaths;

•

lack of efficacy or failure to measure a statistically significant clinical benefit within the dose range with an acceptable safety margin during clinical trials;

•

termination of our clinical trials by one or more clinical trial sites;

•

inability or unwillingness of patients or clinical investigators to follow our clinical trial protocols;

•

inability to monitor patients adequately during or after treatment by us or our CROs;

•

our CROs or clinical study sites failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, deviating from the protocol or dropping out of a study;

•

inability to address any noncompliance with regulatory requirements or safety concerns that arise during the course of a clinical trial;

•

the impact of, and delays related to, health epidemics such as the COVID-19 pandemic;

•

the need to suspend, repeat or terminate clinical trials as a result of non-compliance with regulatory requirements, inconclusive or negative results or unforeseen complications in testing; and

•

the suspension or termination of our clinical trials upon a breach or pursuant to the terms of any agreement with, or for any other reason by, any future strategic collaborator that has responsibility for the clinical development of any of our product candidates.

Changes in regulatory requirements, policies and guidelines may also occur and we may need to significantly modify our clinical development plans to reflect these changes with appropriate regulatory authorities. These changes may require us to renegotiate terms with CROs or resubmit clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial. Our clinical trials may be suspended or terminated at any time by us, the FDA, other regulatory authorities, the IRB overseeing the clinical trial at issue, any of our clinical trial sites with respect to that site, or us.

Any failure or significant delay in commencing or completing clinical trials for our product candidates, any failure to obtain positive results from clinical trials, any safety concerns related to our product candidates, or any requirement to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate would adversely affect our ability to obtain regulatory approval and our commercial prospects and ability to generate product revenue will be diminished.

If we decide to seek orphan drug designation for one or more of our product candidates, we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation for our current or future product candidates that we may develop.

Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is a drug or biologic product intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or where there is no reasonable expectation that the cost of developing the product will be recovered from sales in the United States. We may seek orphan drug designation for certain indications for our product candidates in the future. Orphan drug designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process. Orphan drug designation can entitle a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.

In addition, if a product candidate with an orphan drug designation receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug for the same indication for seven years. The FDA may reduce the seven-year exclusivity if the same drug from a competitor demonstrates clinical superiority to the product with orphan exclusivity or if the FDA finds that the holder of the orphan exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan product to meet the needs of patients with the disease or condition for which the drug was designated. Even if one of our product candidates receives orphan exclusivity, the FDA can still approve other drugs that have a different active ingredient for use in treating the same indication or disease.

In addition, exclusive marketing rights in the United States may be limited if we seek approval for an indication broader than the orphan-designated indication or may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Further, even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs with different active moieties can be approved for the same condition, and while we may seek orphan drug designation for our product candidates, we may never receive such designations. In addition, the FDA may reevaluate the Orphan Drug Act and its regulations and policies. We do not know if, when, or how the FDA may change the orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes the FDA may make to its orphan drug regulations and policies, our business could be adversely impacted.

We may not be able to conduct, or contract with others to conduct, animal testing in the future, which could harm our research and development activities.

Certain laws and regulations relating to drug development require us to test our product candidates on animals before initiating clinical trials involving humans. Animal testing activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the extent the activities of these groups are successful, our research and development activities may be interrupted or delayed.

Risks Related to Third Parties

We rely on third parties to conduct our preclinical studies, and plan to rely on third parties to conduct clinical trials, and those third parties may not perform satisfactorily.

We expect to rely on third-party clinical investigators, CROs, clinical data management organizations and consultants to design, conduct, supervise and monitor certain preclinical studies and any clinical trials. Because we intend to rely on these third parties and will not have the ability to conduct certain preclinical studies or clinical trials independently, we will have less control over the timing, quality and other aspects of such preclinical studies and clinical trials than we would have had we conducted them on our own. These investigators, CROs and consultants will not be our employees and we will have limited control over the amount of time and resources that they dedicate to our programs. Some of these third parties may terminate their engagements with us at any time. We also expect to have to negotiate budgets and contracts with CROs, clinical trial sites and contract manufacturing organizations and we may not be able to do so on favorable terms, which may result in delays to our development timelines and increased costs. If we need to enter into alternative arrangements with, or replace or add any third parties, it would involve substantial cost and require extensive management time and focus, or involve a transition period, and may delay our drug development activities, as well as materially impact our ability to meet our desired clinical development timelines. These third parties may have contractual relationships with other entities, some of which may be our competitors, which may draw time and resources from our programs. The third parties with which we may contract might not be diligent, careful or timely in conducting our preclinical studies or clinical trials, resulting in the preclinical studies or clinical trials being delayed or unsuccessful.

Our reliance on these third parties for such drug development activities will reduce our control over these activities. As a result, we will have less direct control over the conduct, timing and completion of preclinical studies and clinical trials and the management of data developed through preclinical studies and clinical trials than would be the case if we were relying entirely upon our own staff. Nevertheless, we will be responsible for ensuring that each of our studies and trials is conducted in accordance with applicable protocol, legal and regulatory requirements and scientific standards, including good laboratory practice (“GLP”), good clinical practice (“ GCP”), cGMP, and cGTP and our reliance on third parties does not relieve us of our regulatory responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA and other regulatory authorities require us to comply with GCP standards, regulations for conducting, recording and reporting the results of clinical trials to assure that data and reported results are reliable and accurate and that the rights, integrity and confidentiality of trial participants are protected. Regulatory authorities enforce these GCP requirements through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs, clinical sites and investigators fail to comply with applicable GCP requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, European Medicines Agency (“EMA”), or other regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. There can be no assurance that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials substantially comply with GCP regulations. In addition, our clinical trials must be conducted with product candidates produced under cGMP regulations and will require a large number of test patients. Our failure or any failure by these third parties to comply with these regulations or to recruit a sufficient number of patients, may require us to repeat clinical trials, which would delay the regulatory approval process. Moreover, our business may be implicated if any of these third parties violates FDA regulatory requirements as well as federal or state healthcare laws and regulations or healthcare privacy and security laws.

If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, or if these third parties need to be replaced, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates. As a result, our financial results and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenue could be delayed.

We depend on strategic partnerships and collaboration arrangements, such as our collaboration arrangements with Spark Therapeutics, Inc. (“Spark”), and Bluerock Therapeutics, Inc. (“Bluerock”), for the application of our gene circuit platform technology to the development and commercialization of potential product candidates in certain indications, and if these arrangements are unsuccessful, this could impair our ability to generate revenues and materially harm our results of operations.

Our business strategy for exploiting the potential of our gene circuit platform technology is dependent upon maintaining our current arrangements and establishing new arrangements with strategic partners, research collaborators and other third parties. We currently have collaboration agreements with Spark and Bluerock. These collaboration agreements provide for, among other things, research funding and significant future payments should certain development, regulatory and commercial milestones be achieved. Under these arrangements, our collaborators are typically responsible for:

•

electing to advance product candidates through preclinical and into clinical development;

•

conducting clinical development and obtaining required regulatory approvals for product candidates; and

•

commercializing any resulting products.

As a result, we may not be able to conduct these collaborations in the manner or on the time schedule we currently contemplate, which may negatively impact our business operations.

Additionally, the development and commercialization of potential product candidates under our collaboration agreements could be substantially delayed, and our ability to receive future funding could be substantially impaired if one or more of our collaborators:

•

shifts its priorities and resources away from our collaborations due to a change in business strategies, or a merger, acquisition, sale or downsizing of its company or business unit;

•

ceases development in therapeutic areas which are the subject of our collaboration;

•

fails to select a product candidate for advancement into preclinical development, clinical development, or subsequent clinical development into a marketed product;

•

changes the success criteria for a particular product candidate, thereby delaying or ceasing development of such product candidate;

•

significantly delays the initiation or conduct of certain activities which could delay our receipt of milestone payments tied to such activities, thereby impacting our ability to fund our own activities;

•

develops a product candidate that competes, either directly or indirectly, with our product candidates;

•

does not obtain the requisite regulatory approval of a product candidate;

•

does not successfully commercialize a product candidate;

•

encounters regulatory, resource or quality issues and is unable to meet demand requirements;

•

exercises its rights under the agreement to terminate the collaboration, or otherwise withdraws support for, or otherwise impairs development under the collaboration;

•

disagrees on the research, development or commercialization of a product candidate resulting in a delay in milestones, royalty payments or termination of research and development activities for such product candidate; and

•

uses our proprietary information or intellectual property in such a way as to jeopardize our rights in such property.

In addition, the termination of our existing collaborations or any future strategic partnership or collaboration arrangement that we enter into may prevent us from receiving any milestone, royalty payment, sharing of profits, and other benefits under such agreement. Furthermore, disagreements with these parties could require or result in litigation or arbitration, which would be time-consuming and expensive. Any of these events could have a material adverse effect on our ability to develop and commercialize any of our product candidates and may adversely impact our business, prospects, financial condition, and results of operations.

We may not be able to enter into additional strategic transactions on acceptable terms, if at all, which could adversely affect our ability to develop and commercialize current and potential future product candidates and technologies, impact our cash position, increase our expenses and present significant distractions to our management.

From time to time, we consider strategic transactions, such as collaborations, regional partnerships for the co-development and/or co-commercialization of our product candidates in selected territories, acquisitions of companies, asset purchases, joint ventures, out- or in-licensing of product candidates or technologies and biomanufacturing partnerships involving our manufacturing facilities and gene circuit platform technology. For example, we will evaluate and, if strategically attractive, seek to enter into collaborations, including with biotechnology or biopharmaceutical companies, contract development manufacturing organizations or hospitals. The competition for collaborators is intense, and the negotiation process is time-consuming and complex. If we are not able to enter into strategic transactions, we may not have access to required liquidity or expertise to further develop our potential future product candidates or our gene circuit platform. Any such collaboration, or other strategic transaction, may require us to incur non-recurring or other charges, increase our near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business.

We also may acquire additional technologies and assets, form strategic alliances or create joint ventures with third parties that we believe will complement or augment our existing business, but we may not be able to realize the benefit of acquiring such assets. Conversely, any new collaboration that we do enter into may be on terms that are not optimal for us, our product candidates or our technologies. These transactions would entail numerous operational and financial risks, including:

•

exposure to unknown liabilities;

•

disruption of our business and diversion of our management’s time and attention in order to negotiate and manage a collaboration or develop acquired products, product candidates or technologies;

•

incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs;

•

higher-than-expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses;

•

difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business;

•

impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership; and

•

the inability to retain key employees of any acquired business.

Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions that we do complete may be subject to the foregoing or other risks and our business could be materially harmed by such transactions. Conversely, any failure to enter any collaboration or other strategic transaction that would be beneficial to us could delay the development and potential commercialization of our product candidates and technologies and have a negative impact on the competitiveness of any product candidate or technology that reaches market.

In addition, to the extent that any future collaborators terminate a collaboration agreement, we may be forced to independently develop our current and future product candidates and technologies, including funding preclinical studies or clinical trials, assuming marketing and distribution costs and maintaining, enforcing and defending intellectual property rights, or, in certain instances, abandon product candidates and technologies altogether, any of which could result in a change to our business plan and have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Manufacturing

The manufacture of biopharmaceutical products is complex and requires significant expertise, including the development of advanced manufacturing techniques and process controls. The process of manufacturing our product candidates is also extremely susceptible to product loss due to contamination, equipment failure or improper installation or operation of equipment, operator error, contamination and inconsistency in yields, variability in product characteristics and difficulties in scaling the production process. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects and other supply disruptions. If microbial, viral or other contaminations are discovered in our product candidates or the manufacturing facilities in which they are made, the facilities may need to be closed for an extended period of time to investigate and remedy the contamination. As a result of the complexities, the cost to manufacture biologics in general, and our cell-based product candidates in particular, is generally higher than traditional small molecule chemical compounds, and the manufacturing process is less reliable and is more difficult to reproduce.

Any adverse developments affecting manufacturing operations for our product candidates, if any are approved, may result in shipment delays, inventory shortages, lot failures, product withdrawals or recalls, or other interruptions in the supply of our products. We may also have to take inventory write-offs and incur other charges and expenses for products that fail to meet specifications, undertake costly remediation efforts or seek more costly manufacturing alternatives. Furthermore, it is too early to estimate our cost of goods sold. The actual cost to manufacture our product candidates could be greater than we expect because we are early in our development efforts.

Construction of our planned in-house manufacturing may be delayed or, even if completed, supply of our product candidates for preclinical and clinical development may become limited or interrupted or may not be of satisfactory quantity or quality, and we will experience delays if we are unable to operate our own manufacturing facility and are required to relay on third party back-up manufacturers.

A key to our strategy is operating our own manufacturing facility. We initiated construction in June 2021 of a dedicated in-house facility to support clinical and commercial-scale production of allogeneic NK cell product candidates in accordance with cGMP and cGTP requirements. We anticipate that this facility will become operational in time to support initial clinical trials for our lead product candidates. Initial manufacturing efforts at our planned facility will focus on our two lead product candidates, SENTI-202 and SENTI-301.

The construction and commissioning of our planned facility may be delayed or may not be completed. As such, we cannot assure that our preclinical or future clinical development product supplies and commercial supplies will not be limited or interrupted. In particular, any change in our plans to construct and operate our own facility, including any decision to rely on third party back-up manufacturers, could require significant effort and expertise because there may be a limited number, if any, of qualified third-party replacements. We do not currently have arrangements in place for a redundant or second-source supply in the event our planned facility does not become operational. Any delays in manufacturing our product candidates could impede, delay, limit or prevent our drug development efforts, which could harm our business, results of operations, financial condition and prospects. Additionally, we may pursue a biomanufacturing partnership in which we grant a third party certain rights to use our manufacturing facility for the manufacture of third parties’ products or product candidates, which could divert our manufacturing capacity and management resources from the manufacture of our product candidates.

We do not currently produce our product candidates in quantities sufficient for preclinical and clinical development, and we do not currently have arrangements with any third parties to produce them for us. We cannot be sure that the manufacturing processes employed by us or the technologies that we incorporate for manufacturing will result in viable or scalable yields of our product candidates that will be safe, effective, and meet market demand.

The manufacturing process for a product candidate is subject to FDA and other regulatory authority review. We and any third-party manufacturers we may contract with must meet applicable manufacturing requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply with regulatory standards, such as cGMP and cGTP. In the event that we or any third-party manufacturer fails to comply with such requirements or to perform obligations in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, we may be forced to or enter into an agreement with another third party, which we may not be able to do on reasonable terms, or at all. In some cases, the technical skills or technology required to manufacture our current and future product candidates may be difficult or impossible to transfer to a third party and a feasible alternative may not exist. If we are required to change manufacturing facilities or manufacturers for any reason, we will be required to verify that the new facilities and procedures comply with quality standards and with all applicable regulations and guidelines. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing process will produce our product candidate according to the specifications previously submitted to the FDA or another regulatory authority. The delays associated with the verification of a new manufacturing could negatively

affect our ability to develop product candidates in a timely manner or within budget. In addition, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between our prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical supplies which could require the conduct of additional clinical trials.

If we receive regulatory approval for any product candidate and we are unable to for any reason to produce sufficient quantities of the product in our own facility, and we are unable to obtain or maintain third-party manufacturing on commercially reasonable terms, we may not be able to commercialize the product candidate successfully. Our or a third party’s failure to execute on our manufacturing requirements and comply with cGMP and cGTP could adversely affect our business in a number of ways, including:

•

an inability to initiate or continue clinical trials of product candidates under development;

•

delay in submitting regulatory applications, or receiving regulatory approvals, for product candidates;

•

loss of the cooperation of potential future collaborators;

•

subjecting third-party manufacturing facilities or our potential future manufacturing facilities to additional inspections by regulatory authorities;

•

requirements to cease distribution or to recall batches of product candidates; and

•

in the event of approval to market and commercialize a product candidate, an inability to meet commercial demands for our products.

Our future in-house manufacturing facility and any third-party manufacturers that we use may be unable to successfully scale the manufacturing of our current or potential future product candidates in sufficient quality and quantity, which would delay or prevent us from developing our current and potential future product candidates and commercializing approved products candidates, if any. We have never operated a cGMP facility before.

In order to conduct clinical trials for our current and potential future product candidates or to commercialize any approved product candidates, we will need to manufacture large quantities of these product candidates. We expect to use our in-house manufacturing facility to produce required quantities of our product candidates upon its planned completion in 2022. We, or any manufacturing partners, may be unable to successfully increase the manufacturing capacity for any current or potential future product candidate in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities and may result in lower yields than initially expected. While we believe our planned cGMP facility will be sufficiently scalable to produce commercial quantities, any significant revisions to the manufacturing process may create delays, which could negatively impact our overall development timelines. In addition, we have never operated a cGMP facility before. We may encounter difficulties in operating the facility or meeting the requirements of the FDA or other regulatory authorities that we have not anticipated. If we cannot successfully scale the manufacture of any current or potential future product candidate in sufficient quality and quantity, the development, testing, clinical trials and commercialization of that product candidate may be delayed or infeasible and regulatory approval or commercial launch of any potential resulting product may be delayed or not obtained, which could significantly harm our business.

We are exposed to a number of risks related to our supply chain for the materials required to manufacture our product candidates.

Manufacturing our product candidates is highly complex and requires sourcing specialty materials. Many of the risks associated with the complexity of manufacturing our final products are applicable to the manufacture and supply of the raw materials. In particular, these starting materials are subject to inconsistency in yields, variability in characteristics, contamination, difficulties in scaling the production process and defects. Similar minor deviations in the manufacturing process for these starting materials could result in supply disruption and

reduced production yields for our final product. In addition, we rely on third parties for the supply of these materials exposing us to similar risks of reliance on third parties as described above with respect to the manufacturing and supply of our drug products.

Our manufacturing processes requires many reagents, some of which are drug substance intermediates used in our manufacturing processes to bring about chemical or biological reactions, and other specialty materials and equipment, some of which are manufactured or supplied by small companies with limited resources and experience to support commercial production. We currently depend on a limited number of vendors for certain materials and equipment used in the manufacture of our product candidates. Some of these suppliers may not have the capacity to support commercial products manufactured under cGMP by biopharmaceutical firms or may otherwise be ill-equipped to support our needs. Reagents and other key materials from these suppliers may have inconsistent attributes and introduce variability into our manufactured product candidates, which may contribute to variable patient outcomes and possible adverse events. We also do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Accordingly, we may experience delays in receiving key materials and equipment to support clinical or commercial manufacturing.

For some of these reagents, equipment, and materials, we rely and may in the future rely on sole source vendors or a limited number of vendors. An inability to continue to source product from any of these suppliers, which could be due to regulatory actions or requirements affecting the supplier, adverse financial or other strategic developments experienced by a supplier, labor disputes or shortages, unexpected demands, or quality issues, could adversely affect our ability to satisfy demand for our product candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct clinical trials, either of which could significantly harm our business. Additionally, in response to governmental shelter-in-place orders resulting from the ongoing COVID-19 pandemic, third-party suppliers and manufacturers on whom we rely may from time to time be required to limit their on-site staff’s availability to conduct activities at their respective facilities, and may encounter problems with shortages of qualified personnel and key contractors, and delays or pauses in the production and delivery of laboratory equipment, materials and supplies necessary for the manufacture of our product candidates. These problems may include workforce reductions, employee absenteeism and attrition, and supply chain failures or delays relating to the ongoing COVID-19 pandemic or other events affecting raw material supply or manufacturing capabilities.

As we continue to develop and scale our manufacturing process, we expect that we will need to obtain rights to and supplies of certain materials and equipment to be used as part of that process. We may not be able to obtain rights to such materials on commercially reasonable terms, or at all, and if we are unable to alter our process in a commercially viable manner to avoid the use of such materials or find a suitable substitute, it would have a material adverse effect on our business. Even if we are able to alter our process so as to use other materials or equipment, such a change may lead to a delay in our clinical development and/or commercialization plans. If such a change occurs for a product candidate that is already in clinical testing, the change may require us to perform both comparability studies and to collect additional data from patients prior to undertaking more advanced clinical trials.

Changes in methods of product candidate manufacturing or formulation may result in the need to perform new clinical trials, which would require additional costs and cause delay.

As product candidates are developed through preclinical to late-stage clinical trials towards approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize yield and manufacturing batch size, minimize costs and achieve consistent quality and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of ongoing, planned or future clinical trials conducted with the altered materials. This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commence product sales and generate revenue.

Risks Related to Our Business and Operations

If the market opportunities for our current and potential future product candidates, including SENTI-202, SENTI-301 and SENTI-401, are smaller than we believe they are, our future product revenues may be adversely affected, and our business may suffer.

Our understanding of the number of people who suffer from diseases that our current product candidates may be able to treat are based on estimates. These estimates may prove to be incorrect, and new studies may reduce the estimated incidence or prevalence of these diseases. The number of patients in the United States or elsewhere may turn out to be lower than expected, may not be otherwise amenable to treatment with our current or potential future product candidates or patients may become increasingly difficult to identify and access, all of which would adversely affect our business prospects and financial condition. In particular, the treatable population for our candidates may further be reduced if our estimates of addressable populations are erroneous or sub-populations of patients do not derive benefit from our product candidates.

Further, there are several factors that could contribute to making the actual number of patients who receive our current or potential future product candidates less than the potentially addressable market. These include the lack of widespread availability of, and limited reimbursement for, new therapies in many underdeveloped markets.

The development and commercialization of cell and gene therapies is highly competitive. We compete with a variety of large pharmaceutical companies, multinational biopharmaceutical companies, other biopharmaceutical companies and specialized biotechnology companies, as well as technology and/or therapeutics being developed at universities and other research institutions. Our competitors are often larger and better funded than we are. Our competitors have developed, are developing or will develop product candidates and processes competitive with ours. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community and any new treatments that are currently in development or that enter the market. We believe that a significant number of product candidates are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may try to develop product candidates. There is intense and rapidly evolving competition in the biotechnology and biopharmaceutical fields. We believe that while our gene circuit platform, its associated intellectual property, the characteristics of our current and potential future product candidates and our scientific and technical know-how together give us a competitive advantage in this space, competition from many sources remains.

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the safety and effectiveness of our product candidates, the ease with which our product candidates can be administered, the timing and scope of regulatory approvals for these product candidates, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing products and product candidates could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any products we may develop. Competitive products and product candidates may make any product we develop obsolete or noncompetitive before we recover the expense of developing and commercializing such product. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our ability to execute our business plan.

Any inability to attract and retain qualified key management, technical personnel and employees would impair our ability to implement our business plan.

Our success largely depends on the continued service of key executive management, advisors and other specialized personnel, including Timothy Lu, our Chief Executive Officer, Philip Lee, our Chief Technology Officer, Curt Herberts III, our Chief Operating Officer and Deborah Knobelman, our Chief Financial Officer. Our senior management may terminate their employment with us at any time and will continue to be able to do so after the closing of the Business Combination. For example, Senti’s former Chief Scientific Officer departed Senti in the first quarter of 2022. We do not maintain “key person” insurance for any of our employees. The loss of one or more members of our executive team, management team or other key employees or advisors could delay our research and development programs and have a material adverse effect on our business, financial condition, results of operations and prospects.

Recruiting and retaining qualified scientific and clinical personnel and, if we progress the development of any of our product candidates, commercialization, manufacturing and sales and marketing personnel, will be critical to our success. The loss of the services of members of our senior management or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing members of our senior management and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize our product candidates. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and senior managers, as well as junior, mid-level and senior scientific and medical personnel. Competition to hire from this limited candidate pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high-quality personnel, our ability to pursue our growth strategy will be limited.

We may experience difficulties in managing our growth and expanding our operations.

We have limited experience in therapeutic development. As our current and potential future product candidates enter and advance through preclinical studies and any clinical trials, we will need to expand our development, regulatory and manufacturing capabilities or contract with other organizations to provide these capabilities for us.

To manage our anticipated future growth, we will continue to implement and improve our managerial, operational, and financial systems, expand our facilities, and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the complexity in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. In addition, we have limited experience in managing the manufacturing processes necessary for making cell and gene therapies. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

In addition, future growth imposes significant added responsibilities on members of management, including: identifying, recruiting, integrating, maintaining, and motivating additional employees; managing our internal development efforts effectively, including the clinical and FDA review process for our product candidates, while complying with our contractual obligations to contractors and other third parties; and improving our operational, financial and management controls, reporting systems and procedures.

We may also experience difficulties in the discovery and development of potential future product candidates using our gene circuit platform if we are unable to meet demand as we grow our operations. In the future, we also expect to have to manage additional relationships with collaborators, suppliers and other organizations. Our ability to manage our operations and future growth will require us to continue to improve our operational, financial and management controls, reporting systems and procedures and secure adequate facilities for our operational needs. We may not be able to implement improvements to our management information and control systems in an efficient or timely manner and may discover deficiencies in existing systems and controls.

If any of our product candidates is approved for marketing and commercialization in the future and we are unable to develop sales, marketing and distribution capabilities on our own or enter into agreements with third parties to perform these functions on acceptable terms, we will be unable to successfully commercialize any such future products.

We currently have no sales, marketing or distribution capabilities or experience. We will need to develop internal sales, marketing and distribution capabilities to commercialize each current and potential future product candidate that gains, if ever, FDA or other regulatory authority approval, which would be expensive and time-consuming, or enter into collaborations with third parties to perform these services. If we decide to market any approved products directly, we will need to commit significant financial and managerial resources to develop a marketing and sales force with technical expertise and supporting distribution, administration and compliance capabilities. If we rely on third parties with such capabilities to market any approved products or decide to co-promote products with third parties, we will need to establish and maintain marketing and distribution arrangements with third parties, and there can be no assurance that we will be able to enter into such arrangements on acceptable terms or at all. In entering into third-party marketing or distribution arrangements, any revenue we receive will depend upon the efforts of the third parties and we cannot assure you that such third parties will establish adequate sales and distribution capabilities or be successful in gaining market acceptance for any approved product. If we are not successful in commercializing any product approved in the future, either on our own or through third parties, our business and results of operations could be materially and adversely affected.

Our potential future international operations may expose us to business, political, operational and financial risks associated with doing business outside of the United States.

Our business is subject to risks associated with conducting business internationally. Some of our future clinical trials may be conducted outside of the United States and we may enter into key supply arrangements or do other business with persons outside of the United States. Furthermore, if we or any future collaborator succeeds in developing any products, we anticipate marketing them in the European Union and other jurisdictions in addition to the United States. If approved, we or any future collaborator may hire sales representatives and conduct physician and patient association outreach activities outside of the United States. Doing business internationally involves a number of risks, including but not limited to:

•

multiple, conflicting and changing laws and regulations such as those relating to privacy, data protection and cybersecurity, tax laws, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

•

failure by us to obtain and maintain regulatory approvals for the commercialization of our product candidates in various countries;

•

rejection or qualification of foreign clinical trial data by the competent authorities of other countries;

•

additional potentially relevant third-party patent rights;

•

complexities and difficulties in obtaining, maintaining, protecting and enforcing our intellectual property rights;

•

difficulties in staffing and managing foreign operations;

•

complexities associated with managing multiple payor reimbursement regimes, government payors or patient self-pay systems;

•

limits in our ability to penetrate international markets;

•

financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on demand and payment for our products and exposure to foreign currency exchange rate fluctuations;

•

natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of disease (including the COVID-19 pandemic), boycotts, curtailment of trade and other business restrictions;

•

certain expenses including, among others, expenses for travel, translation and insurance; and

•

regulatory and compliance risks that relate to anti-corruption compliance and record-keeping that may fall within the purview of the U.S. Foreign Corrupt Practices Act, its accounting provisions or its anti-bribery provisions or provisions of anti-corruption or anti-bribery laws in other countries.

Any of these factors could harm our ongoing international operations and supply chain, as well as any future international expansion and operations and, consequently, our business, financial condition, prospects and results of operations.

Our business entails a significant risk of product liability, and our inability to obtain sufficient insurance coverage could have a material adverse effect on our business, financial condition, results of operations and prospects.

As we conduct preclinical studies and future clinical trials of our current and potential future product candidates, we will be exposed to significant product liability risks inherent in the development, testing, manufacturing and marketing of these product candidates. Product liability claims could delay or prevent completion of our development programs. If we succeed in marketing products, such claims could result in an FDA investigation of the safety and effectiveness of our products, our manufacturing processes and facilities or our marketing programs and potentially a recall of our products or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we or any future collaborators may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our employees, principal investigators, consultants and commercial collaborators may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercial collaborators. Misconduct by employees could include intentional failures to comply with FDA regulations, provide accurate information to the FDA, comply with manufacturing standards we may establish, comply with federal and state healthcare fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this

activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a material adverse effect on our business and financial condition, including the imposition of significant criminal, civil and administrative fines or other sanctions, such as monetary penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government-funded healthcare programs, such as Medicare and Medicaid, integrity obligations, reputational harm and the curtailment or restructuring of our operations.

We depend on sophisticated information technology systems and data processing to operate our business. If we experience security or data privacy breaches or other unauthorized or improper access to, use of, or destruction of our proprietary or confidential data, employee data or personal data, we may face costs, significant liabilities, harm to our brand and business disruption.

We rely on information technology systems and data processing that we or our service providers, collaborators, consultants, contractors or partners operate to collect, process, transmit and store electronic information in our day-to-day operations, including a variety of personal data, such as name, mailing address, email addresses, phone number and potentially clinical trial information. Additionally, we, and our service providers, collaborators, consultants, contractors or partners, do or will collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect and share personal information, health information and other information to host or otherwise process some of our anticipated future clinical data and that of users, develop our products, to operate our business, for clinical trial purposes, for legal and marketing purposes, and for other business-related purposes. Our internal computer systems and data processing and those of our third-party vendors, consultants, collaborators, contractors or partners, including future CROs may be vulnerable to a cyber-attack (including supply chain cyber-attacks), malicious intrusion, breakdown, destruction, loss of data privacy, actions or inactions by our employees or contractors that expose security vulnerabilities, theft or destruction of intellectual property or other confidential or proprietary information, business interruption or other significant security incidents. As the cyber-threat landscape evolves, these attacks are growing in frequency, level of persistence, sophistication and intensity, and are becoming increasingly difficult to detect. In addition to traditional computer “hackers,” threat actors, software bugs, malicious code (such as viruses and worms), employee theft or misuse, denial-of-service attacks (such as credential stuffing), phishing and ransomware attacks, sophisticated nation-state and nation-state supported actors now engage in attacks (including advanced persistent threat intrusions). These risks may be increased as a result of COVID-19, owing to an increase in personnel working remotely and higher reliance on internet technology. Furthermore, because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for an extended period.

There can be no assurance that we, our service providers, collaborators, consultants, contractors or partners will be successful in efforts to detect, prevent or fully recover systems or data from all breakdowns, service interruptions, attacks or breaches of systems that could adversely affect our business and operations and/or result in the loss of critical or sensitive data. Any failure by us or our service providers, collaborators, consultants, contractors or partners to detect, prevent, respond to or mitigate security breaches or improper access to, use of, or inappropriate disclosure of any of this information or other confidential or sensitive information, including patients’ personal data, or the perception that any such failure has occurred, could result in claims, litigation, regulatory investigations and other proceedings, significant liability under state, federal and international law, and other financial, legal or reputational harm to us. Further, such failures or perceived failures could result in liability and a material disruption of our development programs and our business operations, which could lead to significant delays or setbacks in our research, delays to commercialization of our product candidates, lost revenues or other adverse consequences, any of which could have a material adverse effect on our business, results of operations, financial condition, prospects and cashflow. For example, the loss or alteration of clinical trial data from future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data.

Additionally, applicable laws and regulations relating to privacy, data protection or cybersecurity, external contractual commitments and internal privacy and security policies may require us to notify relevant stakeholders if there has been a security breach, including affected individuals, business partners and regulators. Such disclosures are costly, and the disclosures or any actual or alleged failure to comply with such requirements could lead to a materially adverse impact on the business, including negative publicity, a loss of confidence in our services or security measures by our business partners or breach of contract claims. There can be no assurance that the limitations of liability in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages if we fail to comply with applicable data protection laws, privacy policies or other data protection obligations related to information security or security breaches.

If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our research, development and manufacturing involve the use of hazardous materials and various chemicals. We maintain quantities of various flammable and toxic chemicals in our facilities that are required for our research, development and manufacturing activities. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. We believe our procedures for storing, handling and disposing of these materials in our facilities comply with the relevant guidelines of the state of California and the Occupational Safety and Health Administration of the U.S. Department of Labor. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards mandated by applicable regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. If an accident occurs, we could be held liable for resulting damages, which could be substantial. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of animals and biohazardous materials. Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of these materials, this insurance may not provide adequate coverage against potential liabilities. Although we have some environmental liability insurance covering certain of our facilities, we may not maintain adequate insurance for all environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of these laws or regulations.

Our business, operations and clinical development plans and timelines could be adversely affected by the effects of health epidemics, including the ongoing COVID-19 pandemic, on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom we may conduct business, including our anticipated contract manufacturers, CROs, shippers and others.

Health epidemics could cause significant disruption in our operations and the operations of third-party manufacturers, CROs and other third parties upon whom we rely. For example, in March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. Since then, COVID-19 has spread to most countries and all 50 states within the United States, and the U.S. government has, at various times, ordered the closure of all non-essential businesses, imposed social distancing measures, “shelter-in-place” orders and restrictions on travel between the United States, Europe and certain other countries. The global pandemic and government measures taken in response have also had a significant impact on businesses and commerce worldwide, as worker shortages have occurred, supply chains have been disrupted, facilities and production have been suspended across a variety of industries, and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel, has fallen. In connection with COVID-19, we implemented work-from-home policies for most employees. The effects of government orders and our work-from-home policies may negatively impact productivity, disrupt our business and delay our clinical programs and timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course.

If our relationships with our suppliers or other vendors are terminated or scaled back as a result of the COVID-19 pandemic or other health epidemics, we may not be able to enter into arrangements with alternative suppliers or vendors or do so on commercially reasonable terms or in a timely manner. Switching or adding additional suppliers or vendors involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new supplier or vendor commences work. As a result, delays may occur, which could adversely impact our ability to meet our desired clinical development and any future commercialization timelines. Although we carefully manage our relationships with our suppliers and vendors, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not harm our business.

In addition, our preclinical studies and future clinical trials may be affected by the COVID-19 pandemic. Clinical site initiation, patient enrollment and activities that require visits to clinical sites, including data monitoring, may be delayed due to prioritization of hospital resources toward the COVID-19 pandemic or concerns among patients about participating in clinical trials during a pandemic. Some patients may have difficulty following certain aspects of clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. These challenges may also increase the costs of completing our clinical trials. Similarly, if we are unable to successfully recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 or experience additional restrictions by their institutions, city or state, our preclinical studies and future clinical trial operations could be adversely impacted.

The spread of COVID-19, which has caused a broad impact globally, may materially affect us economically. While the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic has resulted in significant volatility for global financial markets, resulting in economic uncertainty that could continue to significantly impact our business and operations and may reduce our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business and the value of our common stock. In addition, any recurrence or new increases in the rates and severity of COVID-19 infection could cause other widespread or more severe impacts depending on where infection rates are highest.

Further, we may experience additional disruptions that could severely impact our business and future clinical trials, including:

•

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;

•

interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and approval timelines;

•

limitations on employee resources that would otherwise be focused on the conduct of our preclinical studies and clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people;

•

risk that participants enrolled in our clinical trials will acquire COVID-19 while the clinical trial is ongoing, which could impact the results of the clinical trial, including by increasing the number of observed adverse events; and

•

refusal of the FDA or other regulatory authorities to accept data from clinical trials in these affected geographies.

In particular, three vaccines for COVID-19 have been granted Emergency Use Authorization by the FDA, and two of those later received marketing approval. Additional vaccines may be authorized or approved in the future. The resultant demand for vaccines and potential for manufacturing facilities and materials to be commandeered under the Defense Production Act of 1950, or equivalent foreign legislation, may make it more difficult to obtain materials or manufacturing slots for the product candidates needed for our clinical trials, which could lead to delays in these trials. These and similar, and perhaps more severe, disruptions in our operations could have a material adverse effect on our business, results of operations, cash flows, financial condition and/or prospects.

As a result of the COVID-19 public health emergency, we may be required to develop and implement additional clinical trial policies and procedures designed to help protect subjects from the COVID-19 virus. The ultimate impact of the COVID-19 pandemic on our business operations is highly uncertain and subject to change and will depend on future developments, including new regulatory requirements and changes to existing regulations.

The global pandemic of COVID-19 continues to evolve rapidly. We do not yet know the full extent of potential delays or impacts on our business, our future clinical trials, healthcare systems or the global economy as a whole that may result from the ongoing COVID-19 pandemic. However, these effects could have a material impact on our operations, and we continue to monitor the COVID-19 situation closely. To the extent the COVID-19 pandemic adversely affects our business, results of operations, cash flows, financial condition and/or prospects, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section.

Our business, operations, financial position and clinical development plans and timelines, and our ability to consummate the Business Combination, could be materially adversely affected by the continuing military action in Ukraine.

As a result of the military action commenced in February 2022 by the Russian Federation and Belarus in Ukraine, and related economic sanctions imposed by certain governments, our ability to consummate the Business Combination, and our financial position and operations following the Business Combination, may be materially and adversely affected. As our ability to continue to operate following the Business Combination will be dependent on raising debt and equity finance, any adverse impact to those markets as a result of this military action, including due to increased market volatility, decreased availability in third-party financing and/or a deterioration in the terms on which it is available (if at all), could negatively impact our business, operations or financial position. The extent of any potential impact is not yet determinable, however.

Risks Related to Our Intellectual Property

Our success depends in part on our ability to obtain and maintain protection for our owned and in-licensed intellectual property rights and proprietary technology. We rely on a combination of patents, trademarks, trade secret protection and confidentiality agreements, including in-licenses of intellectual property rights and biologic materials of others, to protect our current or future platform technologies, product candidates, methods used to manufacture our current or future product candidates and methods for treating patients using our current or future product candidates.

We own or in-license patents and patent applications relating to our platform technologies and product candidates. There is no guarantee that any patents covering our platform technologies or product candidates will issue from the patent applications we own, in-license or may file in the future, or, if they do, that the issued claims will provide adequate protection for our platform technologies or product candidates, or any meaningful competitive advantage. Further, there cannot be any assurance that such patents issued will not be infringed, designed around, invalidated by third parties or effectively prevent others from commercializing competitive technologies, products or product candidates.

The patent prosecution process is expensive, complex and time-consuming. Patent license negotiations also can be complex and protracted, with uncertain results. We may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patents and patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. The patent applications that we own or in-license may fail to result in issued patents, and,

even if they do issue as patents, such patents may not cover our current or future technologies or product candidates in the United States or in other countries or provide sufficient protection from competitors. In addition, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after issuance. We do not have exclusive control over the preparation, filing and prosecution of patent applications under certain of our in-license agreements, and we may not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the rights to patents, that we out-license to third parties. Therefore, these patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Even if our owned or in-licensed patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative product candidates in a non-infringing manner.

Further, although we make reasonable efforts to ensure patentability of our inventions, we cannot guarantee that all of the potentially relevant prior art relating to our owned or in-licensed patents and patent applications has been found. For example, publications of discoveries in scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, and in some cases not at all. Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our platform technologies, our product candidates, or the use of our technologies. We thus cannot know with certainty whether we or our licensors were the first to file for patent protection of such inventions. In addition, the United States Patent and Trademark Office (“USPTO”) might require that the term of a patent issuing from a pending patent application be disclaimed and limited to the term of another patent that is commonly owned or names a common inventor. There is no assurance that all potentially relevant prior art relating to our owned or in-licensed patent applications has been found. For this reason, and because there is no guarantee that any prior art search is absolutely correct and comprehensive, we may be unaware of prior art that could be used to invalidate an issued patent or to prevent our owned or in-licensed patent applications from issuing as patents. Invalidation of any of our patent rights, including in-licensed patent rights, could materially harm our business.

Moreover, the patent positions of biotechnology companies like ours are generally uncertain because they may involve complex legal and factual considerations that have, in recent years, been the subject of legal development and change. The relevant patent laws and their interpretation, both inside and outside of the United States, is also uncertain. Changes in either the patent laws or their interpretation in the United States and other jurisdictions may diminish our ability to protect our platform technology or product candidates and could affect the value of such intellectual property. In particular, our ability to stop third parties from making, using, selling, offering to sell or importing products that infringe, misappropriate or otherwise violate our intellectual property will depend in part on our success in obtaining and enforcing patent claims that cover our platform technology, product candidates, inventions and improvements. We cannot guarantee that patents will be granted with respect to any of our owned or licensed pending patent applications or with respect to any patent applications we may file or license in the future, nor can we be sure that any patents that may be granted to us or our licensors in the future will be commercially useful in protecting our products, the methods of use or manufacture of those products. Additionally, third parties, including our former employees and collaborators, may challenge the ownership or inventorship of our patent rights to claim that they are entitled to ownership and inventorship interest, and we may not be successful in defending against such claims. However, we are not currently facing any such challenges. Moreover, issued patents do not guarantee the right to practice our technology in relation to the commercialization of our products. Issued patents only allow us to block—in some cases—potential competitors from practicing the claimed inventions of the issued patents.

The issuance, scope, validity, enforceability and commercial value of our pending patent rights are uncertain. The standards applied by the USPTO and foreign patent offices in granting patents are not always certain and moreover, are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in patents. Our pending and future patent applications may not result in patents being issued in the United States or in other jurisdictions

which protect our technology or products or which effectively prevent others from commercializing competitive technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our owned or in-licensed patent applications or narrow the scope of any patent protection we may obtain from our owned or in-licensed patent applications. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States.

Further, patents and other intellectual property rights in the pharmaceutical and biotechnology space are evolving and involve many risks and uncertainties. For example, third parties may have blocking patents that could be used to prevent us from commercializing our product candidates and any future product candidates and practicing our proprietary technology, and any issued patents may be challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related products or could limit the term of patent protection that otherwise may exist for our product candidate and any future product candidates. In addition, the scope of the rights granted under any issued patents may not provide us with protection or competitive advantages against competitors or other parties with similar technology. Additionally, our competitors may initiate legal proceedings, such as declaratory judgment actions in federal court or reexaminations or an inter partes review at the USPTO in an attempt to invalidate or narrow the scope of our patents. However, we are not currently facing any such proceedings. Furthermore, our competitors or other parties may independently develop similar technologies that are outside the scope of the rights granted under any issued patents. For these reasons, we may face competition with respect to our product candidates and any future product candidates. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any particular product candidate can be commercialized, any patent protection for such product candidate may expire or remain in force for only a short period following commercialization, thereby reducing the commercial advantage the patent provides.

Even if patents do successfully issue from our owned or in-licensed patent application, and even if such patents cover our current or any future technologies or product candidates, third parties may challenge their validity, enforceability or scope, which may result in such patents being narrowed, invalidated, or held unenforceable. Any successful challenge to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of any current or future technologies or product candidates that we may develop. Likewise, if patent applications we own or have in-licensed with respect to our development programs and current or future technologies or product candidates fail to issue, if their breadth or strength is threatened, or if they fail to provide meaningful exclusivity, other companies could be dissuaded from collaborating with us to develop current or future technologies or product candidates. Lack of valid and enforceable patent protection could threaten our ability to commercialize current or future products and could prevent us from maintaining exclusivity with respect to the invention or feature claimed in the patent applications. Any failure to obtain or any loss of patent protection could have a material adverse impact on our business and ability to achieve profitability. We may be unable to prevent competitors from entering the market with a product that is similar or identical to any of our current or potential future product candidates or from utilizing technologies similar to those in our gene circuit platform technologies.

The filing of a patent application or the issuance of a patent is not conclusive as to its ownership, inventorship, scope, patentability, validity or enforceability. Issued patents and patent applications may be challenged in the courts and in the patent office in the United States and abroad. For example, our patent applications or patent applications filed by our licensors, or any patents that grant therefrom, may be challenged through third-party submissions, opposition or derivation proceedings. By further example, any issued patents that may result from our owned or in-licensed patent applications may be challenged through reexamination, inter partes review or post-grant review proceedings before the USPTO, or in declaratory judgment actions or counterclaims. An adverse determination in any such submission, proceeding or litigation could prevent the issuance of, reduce the scope of, invalidate or render unenforceable our owned or in-licensed patent rights, result in the loss of exclusivity, limit our ability to stop others from using or commercializing similar or identical platforms and product candidates, or allow third parties to compete directly with us without payment to us. In addition, if the breadth or strength of protection provided by any patents that might result from our owned or

in-licensed patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future platforms or product candidates. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Moreover, we currently co-own certain patent applications with third parties and may in the future co-own additional patents and patent applications with third parties. If we are unable to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patent application, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. We may need the cooperation of any such co-owners to enforce such patents against third parties, and such cooperation may not be provided to us. Any of the foregoing could have a material adverse effect on our competitive position, business prospects and financial conditions.

Our in-licensed patent rights may be subject to a reservation of rights by one or more third parties, such as the U.S. government. In addition, our rights in such inventions may be subject to certain requirements to manufacture product candidates embodying such inventions in the United States. Any exercise by the U.S. government of such rights could harm our competitive position, business, financial condition, results of operations and prospects.

The patent protection and patent prosecution for some of our product candidates and technologies may be dependent on third parties.

While we normally seek to obtain the right to control prosecution, maintenance and enforcement of the patents relating to our product candidates and technologies, there may be times when the filing and prosecution activities for patents and patent applications relating to our product candidates and technologies are controlled by our licensors or collaborators. Our licensors may not successfully prosecute the patent applications to which we are licensed. Even if patents are issued in respect of these patent applications, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue such litigation less aggressively than we would.

If any of our licensors or collaborators fail to prosecute, maintain and enforce such patents and patent applications in a manner consistent with the best interests of our business, including by payment of all applicable fees for patents covering our product candidates and technologies, we could lose our rights to the intellectual property or our exclusivity with respect to those rights, our ability to develop and commercialize those product candidates and technologies may be adversely affected and we may not be able to prevent competitors from making, using and selling competing product candidates. In addition, even where we have the right to control patent prosecution of patents and patent applications we have licensed to and from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensees, our current and future licensors and their counsel that took place prior to the date upon which we assumed control over patent prosecution.

Further, we may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain of the intellectual property that is licensed to us. It is possible that the licensors’ infringement proceeding(s) or defense activities may be less vigorous than had we conducted them ourselves.

We may be unable to acquire or in-license any relevant third-party intellectual property rights that we identify as necessary or important to our business operations.

Because our development programs may in the future require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to acquire, in-license or use these third-party proprietary rights. We may be unable to acquire or in-license any compositions, methods of use, processes or other third-party intellectual property rights from third parties that we identify as necessary for our product candidates. The licensing of third-party intellectual property rights is a competitive area, and more established

companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. More established companies may have a competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. If we are unable to license such technology, or if we are forced to license such technology on unfavorable terms, our business could be materially harmed. If we are unable to obtain a necessary license, we may be unable to develop or commercialize the affected current or future product candidates, which could materially harm our business, and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties or other forms of compensation. Any of the foregoing could harm our competitive position, business, financial condition, results of operations and prospects.

Further, our licensors may retain certain rights under their agreements with us, including the right to use the underlying technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

Additionally, some intellectual property that we have in-licensed or that we own may have been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights, and limit our ability to contract with non-U.S. manufacturers. As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future product candidates pursuant to the Bayh-Dole Act of 1980 (“Bayh-Dole Act”) and implementing regulations. These U.S. government rights in certain inventions developed under a government-funded program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government may have the right to require us or our licensors to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”). More specifically, certain currently in-licensed patents that cover certain split, universal and programmable chimeric antigen receptor technology may be subject to march-in-rights. This technology is not embodied in any of our current product candidates. In addition, certain currently in-licensed patents that cover certain components and process for regulating the expression of a fusion protein with the use of a protease inhibitor are subject to march-in-rights, which technology can be embodied in certain regulator dial gene circuits. We also own a patent family claiming an invention made under research partially funded by the federal government. Such invention covers mesenchymal stem cells that express combinations of immune effectors for autoimmunity. While the foregoing invention is not embodied in any current product candidates, it is subject to march-in-rights. The U.S. government also has the right to take title to these inventions made through government funded programs if we, or the applicable licensor, fail to disclose the invention to the government and fail to file an application to register the intellectual property within specified time limits. These time limits have recently been changed by regulation, and may change in the future. Intellectual property generated under a government-funded program is also subject to certain reporting requirements, compliance with which may require us or the applicable licensor to expend substantial resources. In addition, the U.S. government requires that any products embodying the subject invention or produced through the use of the subject invention be manufactured substantially in the United States. The manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. product manufacturers for products covered by such intellectual property. To the extent any of our current or future intellectual property is generated through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.

We currently, and in the future may continue to, enter into agreements involving licenses or collaborations that provide for access or sharing of intellectual property. These intellectual property-related agreements may impose certain obligations and restrictions on our ability to develop and commercialize our product candidates and technologies that are the subject of such licenses.

We license rights from third parties to use certain intellectual property relevant to one or more of our current and future product candidates. In the future, we may need to obtain additional licenses from others to advance our research and development activities or allow the commercialization of our current and future product candidates we may identify and pursue. These existing license agreements impose, and any future license agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement or other obligations on us. For example, we are a party to three license agreements with the U.S. Department of Health and Human Services, as represented by the National Cancer Institute (“NCI”), for intellectual property relevant to our product candidates. For a more detailed description of the license agreements with NCI, see the section titled “Business—Material License and Collaboration Agreements.”

In addition, certain of our future agreements with third parties may limit or delay our ability to consummate certain transactions, may impact the value of those transactions, or may limit our ability to pursue certain activities. For example, we may in the future enter into license agreements that are not assignable or transferable, or that require the licensor’s express consent in order for an assignment or transfer to take place.

Further, we or our licensors, if any, may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we or our licensors fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business, financial conditions, results of operations and prospects.

Furthermore, we may not have the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents and patent applications that we license from third parties. In certain circumstances, our licensed patent rights are subject to our reimbursing our licensors for their patent prosecution and maintenance costs. If our licensors and future licensors fail to prosecute, maintain, enforce and defend patents we may license, or lose rights to licensed patents or patent applications, our licensed rights may be reduced or eliminated. In such circumstances, our right to develop and commercialize any of our products or product candidates that is the subject of such licensed rights could be materially adversely affected. Even where we have the right to control prosecution of patents and patent applications under license from third parties, we may still be adversely affected or prejudiced by actions or inactions of our predecessors or licensors and their counsel that took place prior to us assuming control over patent prosecution.

Our technology acquired or licensed currently or in the future from various third parties is or may be subject to retained rights. Our predecessors or licensors do and may retain certain rights under their agreements with us, including the right to use the underlying technology for non-commercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether our predecessors or licensors limit their use of the technology to these uses, and we could incur substantial expenses to enforce our rights to our licensed technology in the event of misuse.

If we are limited in our ability to utilize acquired or licensed technologies, or if we lose our rights to critical in-licensed technology, we may be unable to successfully develop, out-license, market and sell our product candidates, which could prevent or delay new product introductions. Our business strategy depends on the successful development of acquired technologies and licensed technology into commercial product candidates. Therefore, any limitations on our ability to utilize these technologies may impair our ability to develop, out-license or market and sell our product candidates.

If we fail to comply with our obligations under any existing or future license, collaboration or other intellectual property-related agreements, we may be required to pay damages and could lose intellectual property rights that may be necessary for developing, commercializing and protecting our current or future technologies or product candidates or we could lose certain rights to grant sublicenses.

We have certain obligations to third-party licensors from whom we license certain patent rights that are relevant to one or more current and future product candidates. In the future, we may need to obtain additional licenses from other third parties to advance our research and development activities or allow the commercialization of our current and future product candidates. Our existing license agreements impose, and any future license agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement or other obligations on us. For a more detailed description of our existing license agreements, see the section titled “Business—Material License and Collaboration Agreements.” If we breach any of these obligations, including diligence obligations with respect to development and commercialization of product candidates covered by the intellectual property licensed to us, or use the intellectual property licensed to us in an unauthorized manner or we are subject to bankruptcy-related proceedings, we may be required to pay damages and the licensor may have the right to terminate the respective agreement or materially modify the terms of the license, such as by rendering currently exclusive licenses non-exclusive. License termination or modification could result in our inability to develop, manufacture and sell products that are covered by the licensed intellectual property or could enable a competitor to gain access to the licensed intellectual property.

In certain circumstances, our licensed patent rights are subject to our reimbursing our licensors for their patent prosecution and maintenance costs. If our licensors and future licensors fail to prosecute, maintain, enforce and defend patents we may license, or lose rights to licensed patents or patent applications, our licensed rights may be reduced or eliminated. In such circumstances, our right to develop and commercialize any of our products or product candidates that are the subject of such licensed rights could be materially adversely affected.

Our current or future licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing, misappropriating or otherwise violating the licensor’s intellectual property rights. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products if infringement or misappropriation were found, those amounts could be significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in products that we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize products, we may be unable to achieve or maintain profitability.

Disputes may arise between us and our present and future licensors regarding intellectual property subject to a licensing agreement, including:

•

the scope of rights granted under the license agreement and other interpretation-related issues, including but not limited to our right to transfer or assign the license;

•

whether and the extent to which our product candidates, technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

•

our right to sublicense patents and other rights to third parties, including the terms and conditions thereof;

•

our diligence obligations with respect to the development and commercialization of our product candidates that are covered by the license agreement, and what activities satisfy those diligence obligations;

•

our right to transfer or assign the license;

•

the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our collaborators; and

•

the priority of invention of patented technology.

If disputes over intellectual property that we license in the future prevent or impair our ability to maintain our licensing arrangements on acceptable terms, we may not be able to successfully develop and commercialize the affected product candidates, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, the agreements under which we currently license intellectual property or technology from the National Cancer Institute (“NCI”) and other third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, while we currently do not have any liens, security interests, or other encumbrances on the intellectual property that we own, we may, in the future, need to obtain a loan or a line of credit that will require that we put up our intellectual property as collateral to our lenders or creditors. If we do so, and we violate the terms of any such loan or credit agreement, our lenders or creditors may take possession of such intellectual property, including the rights to receive proceeds derived from such intellectual property.

Patent terms may not be able to protect our competitive position for an adequate period of time with respect to our current or future technologies or product candidates.

Patents have a limited lifespan. The term of individual patents and applications in our portfolio depends upon the legal term of patents in the countries in which they are obtained. In most countries in which we file, including the United States, the patent term is 20 years from the earliest date of filing a non-provisional patent application. Extensions of patent term may be available, but there is no guarantee that we would have patents eligible for extension, or that we would succeed in obtaining any particular extension, and no guarantee any such extension would confer a patent term for a sufficient period of time to exclude others from commercializing product candidates similar or identical to ours. In the United States, the term of a patent may be eligible for patent term adjustment, which permits patent term restoration as compensation for delays incurred at the USPTO during the patent prosecution process. In addition, for patents that cover an FDA-approved drug, the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Act”) permits a patent term extension of up to five years beyond the expiration of the patent. While the length of the patent term extension is related to the length of time the drug is under regulatory review, patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, and only one patent per approved drug—and only those claims covering the approved drug, a method for using it or a method for manufacturing it—may be extended under the Hatch-Waxman Act. Similar provisions are available in Europe and other foreign jurisdictions to extend the term of a patent that covers an approved drug. In the future, if and when our products receive FDA approval or applicable approval in other jurisdictions, we expect to apply for patent term extensions on issued patents covering those products in the United States and other jurisdiction where such extensions are available; however, there is no

guarantee that the applicable authorities, including the FDA in the United States, will agree with our assessment of whether such extensions should be granted, and if granted, the length of such extensions. We also may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced. Further, if this occurs, our competitors may be able to launch their products earlier by taking advantage of our investment in development and clinical trials along with our clinical and preclinical data. This could have a material adverse effect on our business and ability to achieve profitability.

The life of a patent and the protection it affords are limited. As a result, our owned and in-licensed patent portfolio provides us with limited rights that may not last for a sufficient period of time to exclude others from commercializing product candidates similar or identical to ours. Even if patents covering our product candidates are obtained, once the patent life has expired, we may be open to competition from competitive products, including generics or biosimilars. For example, given the large amount of time required for the research, development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our current or any future technologies or product candidates.

Changes in either the patent laws or interpretation of the patent laws in the United States or elsewhere could increase the uncertainties and costs surrounding the prosecution of patent applications and the enforcement or defense of issued patents. The United States has enacted and implemented wide-ranging patent reform legislation. On September 16, 2011, the Leahy-Smith America Invents Act (the “Leahy-Smith Act”) was signed into law, which could increase the uncertainties and costs surrounding the prosecution of our owned or in-licensed patent applications and the enforcement or defense of any future owned or in-licensed issued patents. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art, may affect patent litigation and switch the U.S. patent system from a “first-to-invent” system to a “first-to-file” system. Under a first-to-file system, assuming the other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to the patent on an invention regardless of whether another inventor had made the invention earlier. A third party that files a patent application in the USPTO after March 16, 2013, but before us, could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will require us to be cognizant of the time from invention to filing of a patent application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either (i) file any patent application related to our product candidates or (ii) invent any of the inventions claimed in our or our licensor’s patents or patent applications. The Leahy-Smith Act also allows third-party submission of prior art to the USPTO during patent prosecution and sets forth additional procedures to challenge the validity of a patent by USPTO-administered post-grant proceedings, including derivation, reexamination, inter partes review, post-grant review and interference proceedings. The USPTO developed additional regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, and, in particular, the first-to-file provisions, became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our owned or in-licensed patent applications and the enforcement or defense of our issued owned or in-licensed patents, all of which could have a material adverse impact on our business prospects and financial condition.

As referenced above, for example, courts in the U.S. continue to refine the heavily fact-and-circumstance-dependent jurisprudence defining the scope of patent protection available for therapeutics, narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. This creates uncertainty about our ability to obtain patents in the future and the value of such patents. In addition, the patent positions of companies in the development and commercialization of pharmaceuticals are particularly uncertain. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future. We cannot provide assurance that future developments in U.S. Congress, the federal courts and the USPTO will not adversely impact our owned or in-licensed patents or patent applications. The laws and regulations governing patents could change in unpredictable ways that could weaken our and our licensors’ ability to obtain new patents or to enforce our existing owned or in-licensed patents and patents that we might obtain or in-license in the future. Similarly, changes in patent law and regulations in other countries or jurisdictions or changes in the governmental bodies that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may have a material adverse effect on our and our licensors’ ability to obtain new patents or to protect and enforce our owned or in-licensed patents or patents that we may obtain or in-license in the future.

We may be subject to lawsuits or litigation to protect or enforce our patents or other intellectual property, which could result in substantial costs and liability and prevent us from commercializing our potential products.

Third parties may attempt to invalidate our or our licensors’ intellectual property rights via procedures including but not limited to patent infringement lawsuits, declaratory judgment actions, interferences, oppositions and inter partes reexamination proceedings before the USPTO, U.S. courts and foreign patent offices or foreign courts. An adverse determination in any such submission or proceeding could reduce the scope or enforceability of, or invalidate, our patent rights, which could adversely affect our competitive position. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party in a district court action. Even if such rights are not directly challenged, disputes could lead to the weakening of our or our licensors’ intellectual property rights. Our defense against any attempt by third parties to circumvent or invalidate our intellectual property rights could be costly to us, could require significant time and attention of our management, and could have a material and adverse impact on our profitability, financial condition and prospects or ability to successfully compete.

We or our licensors may find it necessary to pursue claims or to initiate lawsuits to protect or enforce our owned or in-licensed patent or other intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to our owned or in-licensed patent or other intellectual property rights, even if resolved in our favor, could be substantial, particularly in a foreign jurisdiction, and any litigation or other proceeding would divert our management’s attention. Such litigation or proceedings could materially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. Some of our competitors may be able to more effectively sustain the costs of complex patent litigation because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development efforts and materially limit our ability to continue our operations.

If we or our licensors were to initiate legal proceedings against a third party to enforce a patent covering one of our product candidates or our technology, the defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, claiming patent-ineligible subject matter, lack of novelty, indefiniteness, lack of written description, non-enablement, anticipation or obviousness. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO or made a misleading statement during prosecution. The outcome of such invalidity and unenforceability claims is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art of which we or our licensors and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we could lose at least part, and perhaps all, of the patent protection for one or more of our product candidates or certain aspects of our platform technologies. Such a loss of patent protection could have a material adverse effect on our business, financial condition, results of operations and prospects. Patents and other intellectual property rights also will not protect our product candidates and technologies if competitors or third parties design around such product candidates and technologies without legally infringing, misappropriating or violating our owned or in-licensed patents or other intellectual property rights.

We may not be able to protect our intellectual property rights throughout the world, which could negatively impact our business.

Filing, prosecuting and defending patents on current or future technologies or product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some countries do not protect intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other countries. Competitors or other third parties may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export infringing product candidates to territories where we have patent protection or licenses, but enforcement is not as strong as that in the United States. These product candidates may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. The legal systems of certain countries, including certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biotechnology, which could make it difficult for us to stop the infringement of any owned and in-licensed patents we may obtain in other countries, or the marketing of competing products in violation of our intellectual property and proprietary rights generally. Proceedings to enforce our owned or in-licensed intellectual property and proprietary rights in foreign jurisdictions could result in substantial costs and could divert our efforts and attention from other aspects of our business. Such proceedings could also put any owned or in-licensed patents at risk of being invalidated or interpreted narrowly, could put our owned or in-licensed patent applications at risk of not issuing, and could provoke third parties to assert claims against us or our licensors. We or our licensors may not prevail in any lawsuits or other adversarial proceedings that we or our licensors initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our and our licensors’ efforts to enforce such intellectual property and proprietary rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or in-license.

Further, many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of its patents. If we or any of our licensors are forced to grant a license to third

parties with respect to any patents relevant to our business, our competitive position in the relevant jurisdiction may be impaired and our business prospects may be materially adversely affected.

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse impact on the success of our business.

Our commercial success depends, in part, upon our ability or the ability of our potential future collaborators to develop, manufacture, market and sell our current or any future product candidates and to use our proprietary technologies without infringing, misappropriating or violating the proprietary and intellectual property rights of third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions and inter partes review proceedings before the USPTO, U.S. courts, foreign patent offices or foreign courts. As the field of gene and cell therapies advances, patent applications are being processed by national patent offices around the world. There is uncertainty about which patents will issue, and, if they do, there is uncertainty as to when, to whom, and with what claims. Any claims of patent infringement asserted by third parties would be time consuming and could:

•

result in costly litigation that may cause negative publicity;

•

divert the time and attention of our technical personnel and management;

•

cause development delays;

•

prevent us from commercializing any of our product candidates until the asserted patent expires or is held finally invalid or not infringed in a court of law;

•

require us to develop non-infringing technology, which may not be possible on a cost-effective basis;

•

subject us to substantial damages for infringement, which we may have to pay if a court decides that the product candidate or technology at issue infringes on or violates the third party’s rights, and, if the court finds that the infringement was willful, we could be ordered to pay treble damages and the patent owner’s attorneys’ fees; or

•

require us to enter into royalty or licensing agreements, which may not be available on commercially reasonable terms, or at all, or which might be non-exclusive, which could result in our competitors gaining access to the same technology.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations or could otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are pursuing development candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that we may be subject to claims of infringement of the patent rights of third parties. Because patent applications can take many years to issue, there may also be currently pending patent applications that may later result in issued patents that our technology or product candidates may infringe. Further, we cannot guarantee that we are aware of all patents and patent applications potentially relevant to our technology or products. We may not be aware of potentially relevant third-party patents or applications for several reasons. For example, U.S. applications filed before November 29, 2000, and certain U.S. applications filed after that date that will not be filed outside the U.S. remain confidential until a patent issues. Patent applications filed in the United States (after November 29, 2000) and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our product candidates or platform technologies could have been filed by others without our knowledge. Any such patent

application may have priority over our patent applications or patents, which could require us to obtain rights to issued patents covering such technologies. Additionally, claims pending in patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our platform, our product candidates or the use of our technologies.

Although no third party has asserted a claim of patent infringement against us as of the date of this proxy statement/prospectus, others may hold proprietary rights that could prevent our product candidates from being marketed. We or our licensors, or any future strategic collaborator, may be party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our current or any potential future product candidates and technologies, including derivation, reexamination, inter partes review or post-grant review before the USPTO and similar proceedings in jurisdictions outside of the United States such as opposition proceedings. In some instances, we may be required to indemnify our licensors for the costs associated with any such adversarial proceedings or litigation. Third parties may assert infringement claims against us, our licensors or our strategic collaborators based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk that third parties may choose to engage in litigation or other adversarial proceedings with us, our licensors or our strategic collaborators to enforce or otherwise assert their patent rights. Even if we believe such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are not invalid, enforceable and infringed, which could have a material adverse impact on our ability to utilize our platform technologies or to commercialize our current or any future product candidates. In order to successfully challenge the validity of any such U.S. patent in federal court, we would need to overcome a presumption of validity by presenting clear and convincing evidence of invalidity. There is no assurance that a court of competent jurisdiction, even if presented with evidence we believe to be clear and convincing, would invalidate the claims of any such U.S. patent.

Further, we cannot guarantee that we will be able to successfully settle or otherwise resolve such adversarial proceedings or litigation. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or to continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our product candidates. If we, or our licensors, or any future strategic collaborators are found to infringe, misappropriate or violate a third-party patent or other intellectual property rights, we could be required to pay damages, including treble damages and attorney’s fees, if we are found to have willfully infringed. In addition, we, or our licensors, or any future strategic collaborators may choose to seek, or be required to seek, a license from a third party, which may not be available on commercially reasonable terms, if at all. Even if a license can be obtained on commercially reasonable terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us, and we could be required to make substantial licensing and royalty payments. Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our current or future product candidates. We could be forced, including by court order, to cease utilizing, developing, manufacturing and commercializing our platform technologies or product candidates deemed to be infringing. We may be forced to redesign current or future technologies or products. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. Any of the foregoing could have a material adverse effect on our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations.

Thus, it is possible that one or more third parties will hold patent rights to which we will need a license, which may not be available on reasonable terms or at all. If such third parties refuse to grant us a license to such patent rights on reasonable terms or at all, we may be required to expend significant time and resources to redesign our technology, product candidates or the methods for manufacturing our product candidates, or to develop or license replacement technology, all of which may not be commercially or technically feasible. In such case, we may not be able to market such technology or product candidates and may not be able to perform research and development or other activities covered by these patents. This could have a material adverse effect on our ability to commercialize our product candidates and our business and financial condition.

Lastly, if our technology or products are found to infringe the intellectual property rights of third parties, these third parties may assert infringement claims against our licensees and other parties with whom we have business relationships, and we may be required to indemnify those parties for any damages they suffer as a result of these claims. The claims may require us to initiate or defend protracted and costly litigation on behalf of licensees and other parties regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of those parties or may be required to obtain licenses for the products they use.

Intellectual property litigation may lead to unfavorable publicity that harms our reputation and causes the market price of New Senti Common Stock to decline.

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as well as results of hearings, rulings on motions and other interim proceedings or developments in the litigation. If securities analysts or investors regard these announcements as negative, the perceived value of our existing product candidates, approved products, programs or intellectual property could be diminished. Accordingly, the market price of shares of New Senti Common Stock may decline. Such announcements could also harm our reputation or the market for our future products, which could have a material adverse effect on our business.

Intellectual property rights of third parties could adversely affect our ability to commercialize our current or future technologies or product candidates, and we might be required to litigate or obtain licenses from third parties to develop or market our current or future technologies or product candidates, which may not be available on commercially reasonable terms or at all.

Because the gene and cell therapy landscape is still evolving, it is difficult to conclusively assess our freedom to operate without infringing, misappropriating or violating third-party rights. The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect. For example, we may incorrectly determine that our products are not covered by a third-party patent or may incorrectly predict whether a third-party’s pending application will issue with claims of relevant scope. Also, our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect.

There are numerous companies that have pending patent applications and issued patents broadly covering gene and cell therapy generally or covering related inventions that may be relevant for product candidates that we wish to develop. We are aware of third-party patents and patent applications that claim aspects of our current or potential future product candidates and modifications that we may need to apply to our current or potential future product candidates. There are also many issued patents that claim inventions that may be relevant to products we wish to develop. The holders of such patents may be able to block our ability to develop and commercialize the applicable product candidate unless we obtain a license or until such patent expires. In either case, such a license may not be available on commercially reasonable terms or at all, or it may be non-exclusive, which could result in our competitors gaining access to the same intellectual property.

Our competitive position may materially suffer if patents issued to third parties or other third-party intellectual property rights cover our current or future technologies, product candidates or elements thereof or our manufacture or uses relevant to our development plans. In such cases, we may not be in a position to develop or commercialize current or future technologies or product candidates unless we successfully pursue litigation to narrow or invalidate the third-party intellectual property right concerned, or enter into a license agreement with the intellectual property right holder, if available on commercially reasonable terms. There may be issued patents of which we are not aware, held by third parties that, if found to be valid and enforceable, could be alleged to be infringed by our current or future technologies or product candidates. There also may be pending patent applications of which we are not aware that may result in issued patents, which could be alleged to be infringed by our current or future technologies or product candidates. If such an infringement claim should successfully be

brought, we may be required to pay substantial damages or be forced to abandon our current or future technologies or product candidates or to seek a license from any patent holders. No assurances can be given that a license will be available on commercially reasonable terms, if at all.

Third-party intellectual property right holders may also actively bring infringement, misappropriation, or other claims alleging violations of intellectual property rights against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such claims. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or to continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our product candidates. If we fail in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing any of our current or future technologies or product candidates that are held to be infringing, misappropriating or otherwise violating third-party intellectual property rights. We might, if possible, also be forced to redesign current or future technologies or product candidates so that we no longer infringe, misappropriate or violate the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business, which could have a material adverse effect on our financial condition and results of operations.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent protection for certain aspects of our current or future technologies and product candidates, we rely on trade secrets, including confidential and unpatented know-how, technology and other proprietary information, to maintain our competitive position and to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. Elements of our product candidates, including processes for their preparation and manufacture, may involve proprietary know-how, information, or technology that is not covered by patents, and thus for these aspects we may consider trade secrets and know-how to be our primary intellectual property. Our trade secrets include, for example, certain program specific synthesis, formulations, patient selection strategies and certain aspects of our research.

Trade secrets and know-how can be difficult to protect. We seek to protect trade secrets and confidential and unpatented know-how, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to such knowledge, such as our employees, corporate collaborators, outside scientific collaborators, contract research organizations, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants under which they are obligated to maintain confidentiality and to assign their inventions to us. However, we cannot be certain that such agreements have been entered into with all relevant parties, and we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not otherwise gain access (such as through a cybersecurity breach) to our trade secrets or independently develop substantially equivalent information and techniques. Moreover, individuals with whom we have such agreements may not comply with their terms. Any of these parties may breach such agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for any such breaches. In addition, we take other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary technology by third parties.

We may also become involved in inventorship disputes relating to inventions and patents developed by our employees or consultants under such agreements. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret, or securing title to an employee- or consultant-developed invention if a dispute arises, is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts in the United States and certain foreign jurisdictions disfavor or are unwilling to protect trade secrets. We may need to share our proprietary information, including trade secrets, with future business partners, collaborators, contractors and others located in countries at heightened risk of theft of trade secrets, including through direct

intrusion by private parties or foreign actors, and those affiliated with or controlled by state actors. Further, if any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent that competitor from using the technology or information to compete with us. If, in the future, any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be materially and adversely harmed.

We may be subject to claims that we or our employees or consultants have wrongfully used or disclosed alleged trade secrets or other proprietary information of third parties, including our employees’ or consultants’ former employers or their clients.

We are party to various contracts under which we are obligated to maintain the confidentiality of trade secrets or other confidential and proprietary information of third parties, including our licensors and strategic partners. In addition, many of our employees or consultants and our licensors’ employees or consultants were previously employed at universities or biotechnology or biopharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that one or more of these employees or consultants or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of third parties, including former employers of our employees and consultants. Litigation or arbitration may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel or may be enjoined from using such intellectual property. Any such proceedings and possible aftermath would likely divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. A loss of key research personnel or their work product could limit our ability to commercialize, or prevent us from commercializing, our current or future technologies or product candidates, which could materially harm our business. Even if we are successful in defending against any such claims, litigation or arbitration could result in substantial costs and could be a distraction to management.

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

We or our licensors may be subject to claims that former employees, collaborators or other third parties have an interest in our owned or in-licensed patents as an inventor or co-inventor, or in our trade secrets or other intellectual property as a contributor to its development. The failure to name the proper inventors on a patent application can result in the patents issuing thereon being unenforceable. Inventorship disputes may arise from conflicting views regarding the contributions of different individuals named as inventors, the effects of foreign laws where foreign nationals are involved in the development of the subject matter of the patent, conflicting obligations of third parties involved in developing our product candidates or as a result of questions regarding co-ownership of potential joint inventions. For example, we or our licensors may have inventorship disputes arise from conflicting obligations of employees, consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other claims challenging inventorship or our or our licensors’ ownership of our owned or in-licensed patents, trade secrets or other intellectual property. Alternatively, or additionally, we may enter into agreements to clarify the scope of our rights in such intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to our product candidates. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

Also, our licensors may have relied on third-party consultants or collaborators or on funds from third parties, such as the U.S. government, such that our licensors are not the sole and exclusive owners of the patents we in-licensed. If other third parties have ownership rights or other rights to our in-licensed patents, they may be able to license such patents to our competitors, and our competitors could market competing products and technology. This could have a material adverse effect on our competitive position, business, financial condition, results of operations and prospects.

Further, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results of operations and prospects.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents or applications will be due to be paid to the USPTO and various government patent agencies outside of the United States over the lifetime of our owned and in-licensed patents or applications and any patent rights we may own or in-license in the future. The USPTO and various non-U.S. patent offices require compliance with several procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law firms and other professionals to help us comply with these requirements, and we are also dependent on our licensors to take the necessary action to comply with these requirements with respect to our in-licensed intellectual property. In many cases, an inadvertent lapse, including due to the effect of the COVID-19 on us, our patent counsel or other applicable patent maintenance vendors, can be cured by payment of a late fee or by other means in accordance with the applicable rules. There are situations, however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, potential competitors might be able to enter the market with similar or identical product candidates or platforms, which could have a material adverse effect on our business prospects and financial condition.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

We use and will continue to use registered and/or unregistered trademarks or trade names to brand and market ourselves and our products. Our trademarks or trade names may be challenged, infringed, circumvented, declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we use for name recognition by potential collaborators or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively, and our business may be materially adversely affected.

We may also license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and trade names by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names.

Intellectual property rights do not necessarily address all potential threats to our business.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business. The following examples are illustrative:

•

others may be able to create gene circuit technologies that are similar to our technologies or our product candidates, but that are not covered by the claims of any patents that we own, license or control;

•

we or any strategic collaborators might not have been the first to make the inventions covered by the issued patents or pending patent applications that we own, license or control;

•

we or our licensors might not have been the first to file patent applications covering certain of our owned and in-licensed inventions;

•

others may independently develop the same, similar, or alternative technologies without infringing, misappropriating or violating our owned or in-licensed intellectual property rights;

•

it is possible that our owned or in-licensed pending patent applications will not lead to issued patents;

•

issued patents that we own, in-license, or control may not provide us with any competitive advantages, or may be narrowed or held invalid or unenforceable, including as a result of legal challenges;

•

our competitors might conduct research and development activities in the United States and other countries that provide a safe harbor from patent infringement claims for certain research and development activities, as well as in countries where we do not have patent rights, and may then use the information learned from such activities to develop competitive products for sale in our major commercial markets;

•

we may choose not to file a patent application in order to maintain certain trade secrets or know-how, and a third party may subsequently file a patent application covering such trade secrets or know-how; and

•

the patents of others may have an adverse effect on our business.

Should any of these events occur, they could have a material adverse impact on our business, financial condition, results of operations and prospects.

Risks Related to Government Regulation

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

All of our current product candidates are in preclinical development and their risk of failure is high. It is impossible to predict when or if our candidates or any potential future product candidates will prove effective in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical studies for our current product candidates and then conduct extensive clinical trials to demonstrate the safety, purity and potency, or efficacy of that product candidate in humans. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the development process. The results of preclinical studies and clinical trials of any of our current or potential future product candidates may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials.

We are currently conducting IND-enabling studies for our current product candidates. We may experience delays in completing our preclinical studies and initiating or completing our clinical studies. We do not know

whether planned preclinical studies and clinical trials will be completed on schedule or at all, or whether planned clinical trials will begin on time, need to be redesigned, enroll patients on time or be completed on schedule, if at all. Our development programs may be delayed for a variety of reasons, including delays related to:

•

the FDA or other regulatory authorities requiring us to submit additional data or imposing other requirements before permitting us to initiate a clinical trial;

•

obtaining regulatory approval to commence a clinical trial;

•

reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites;

•

obtaining IRB or ethics committee approval at each clinical trial site;

•

recruiting suitable patients to participate in a clinical trial;

•

having patients complete a clinical trial or return for post-treatment follow-up;

•

clinical trial sites deviating from trial protocol or dropping out of a trial;

•

the FDA placing the clinical trial on hold;

•

subjects failing to enroll or remain in our trial at the rate we expect;

•

subjects choosing an alternative treatment for the indication for which we are developing or other product candidates, or participating in competing clinical trials;

•

lack of adequate funding to continue the clinical trial;

•

subjects experiencing severe or unexpected drug-related adverse events;

•

any changes to our manufacturing process that may be necessary or desired;

•

adding new clinical trial sites; and

•

manufacturing sufficient quantities of our product candidates for use in clinical trials.

Furthermore, we expect to rely on our CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials and, while we expect to enter into agreements governing their committed activities, we have limited influence over their actual performance.

We could encounter delays if prescribing physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our current or potential future product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be suspended or terminated by us, our collaborators, the IRBs of the institutions in which such trials are being conducted, the Data Safety Monitoring Board for such trial or by the FDA or other regulatory authorities due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug or therapeutic biologic, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial.

Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or a regulatory authority concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection of the marketing application we submit. Any such delay or rejection could prevent or delay us from commercializing our current or future product candidates.

If we experience delays in the completion of, or termination of, any clinical trial of any of our current or potential future product candidates, the commercial prospects of such product candidate will be harmed, and our ability to generate product revenue from such product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow our product development and approval process and jeopardize our ability to commence product sales and generate revenue. Any of these occurrences may have a material adverse effect on our business, financial condition, results of operations and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our current or potential future product candidates.

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize our current or potential future product candidates.

Our current and any potential future product candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of therapeutic biologics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required to be successfully completed in the U.S. and in many foreign jurisdictions before a new drug or therapeutic biologic can be marketed. Satisfaction of these and other regulatory requirements is costly, time-consuming, uncertain and subject to unanticipated delays. It is possible that none of the product candidates we may develop will obtain the regulatory approvals necessary for us or our potential future collaborators to begin selling them.

We have very limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals, including approval by the FDA and other regulatory authorities. The time required to obtain FDA and other approvals is unpredictable but typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the product candidate. The standards that the FDA and its foreign counterparts use when regulating us require judgment and can change, which makes it difficult to predict with certainty how they will be applied. Any analysis we perform of data from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative action, or from changes in regulatory policy during the period of product development, clinical trials and FDA regulatory review in the United States and other jurisdictions. It is impossible to predict whether legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed, or what the impact of such changes, if any, may be.

Any delay or failure in obtaining required approvals could have a material adverse effect on our ability to generate revenue from the particular product candidate for which we are seeking approval. Further, we and our potential future collaborators may never receive approval to market and commercialize any product candidate. Even if we or a potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings.

Once a product obtains regulatory approval, numerous post approval requirements apply, including periodic monitoring and reporting obligations, review of promotional material, reports on ongoing clinical trials and adverse events and inspections of manufacturing facilities. In addition, material changes to approved products, including any changes to the manufacturing process or labeling, require further review by the appropriate authorities before marketing. Approvals may also be withdrawn or revoked due to safety, effectiveness or potency concerns, including as a result of adverse events reported in patients or ongoing clinical trials, or failure to comply with cGMP. In addition to revocation or withdrawal of approvals, we and our partners may be subject to warnings, fines, recalls, criminal prosecution or other sanctions if we fail to comply with regulatory requirements. If we or our partners are unable to obtain or maintain regulatory approvals for our products and product candidates, our business, financial position, results of operations and future growth prospects will be

negatively impacted and we or our partners may be subject to sanctions. If any of our product candidates prove to be ineffective, unsafe or commercially unviable, we may have to re-engineer our current or potential future product candidates, and our entire pipeline could have little, if any, value, which could require us to change our focus and approach to product candidate discovery and therapeutic development, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

We will also be subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process varies among countries and may include all of the risks associated with FDA approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain approval may differ from that required to obtain FDA approval.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.

If we succeed in developing any products, we intend to market them in the United States as well as the European Union and other foreign jurisdictions. In order to market and sell our products in other jurisdictions, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, but a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA or EMA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we or any partner we work with fail to comply with the regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced, and our ability to realize the full market potential of our product candidates will be harmed.

We may in the future conduct certain of our clinical trials for our product candidates outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case our development plans will be delayed, which could materially harm our business.

We may in the future choose to conduct one or more of our clinical trials for our product candidates outside the United States. Although the FDA may accept data from clinical trials conducted outside the United States, acceptance of this data is subject to certain conditions imposed by the FDA. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will not approve the application on the basis of foreign data alone unless (i) those data are applicable to the U.S. population and U.S. medical practice; (ii) the studies were performed by clinical investigators of recognized competence; and (iii) the data are considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. For studies that are conducted only at sites outside of the United States and not subject to an IND, the FDA requires the clinical trial to have been conducted in accordance with GCPs, and the FDA must be able to validate the data from the clinical trial through an on-site inspection if it deems such

inspection necessary. For such studies not subject to an IND, the FDA generally does not provide advance comment on the clinical protocols for the studies, and therefore there is an additional potential risk that the FDA could determine that the study design or protocol for a non-U.S. clinical trial was inadequate, which could require us to conduct additional clinical trials. There can be no assurance the FDA will accept data from clinical trials conducted outside of the United States. If the FDA does not accept data from our clinical trials of our product candidates, it would likely result in the need for additional clinical trials, which would be costly and time consuming and delay or permanently halt our development of our product candidates.

Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any similar foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any similar foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction.

Conducting clinical trials outside the United States also exposes us to additional risks, including risks associated with:

•

additional foreign regulatory requirements;

•

foreign exchange fluctuations;

•

compliance with foreign manufacturing, customs, shipment and storage requirements;

•

cultural differences in medical practice and clinical research; and

•

diminished protection of intellectual property in some countries.

Even if we receive regulatory approval for any of our current or potential future product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our current or potential future product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products.

Any regulatory approvals that we or potential future collaborators obtain for any of our current or potential future product candidates will be subject to limitations on the approved indicated uses for which a product may be marketed or may be subject to the conditions of approval, or contain requirements for potentially costly post-marketing testing, and surveillance to monitor the safety and efficacy of such product candidate. In addition, if the FDA or any other regulatory authority approves any of our current or potential future product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, import, export, advertising, promotion and recordkeeping for such product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP and good clinical practices for any clinical trials that we conduct post-approval. In addition, manufacturers and manufacturers’ facilities are required to comply with extensive FDA and comparable foreign regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to cGMP and cGTP regulations and applicable product tracking and tracing requirements.

Later discovery of previously unknown problems with a product candidate, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

•

restrictions on the marketing or manufacturing of the product candidate, withdrawal of the product candidate from the market or voluntary or mandatory product recalls;

•

fines, warning letters, untitled letters or holds on clinical trials;

•

refusal by the FDA to approve pending applications or supplements to approved applications filed by us or our strategic collaborators;

•

suspension or revocation of product approvals;

•

suspension of any ongoing clinical trials;

•

product seizure or detention or refusal to permit the import or export of products; and

•

injunctions or the imposition of civil or criminal penalties or monetary fines.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue.

The FDA has the authority to require a risk evaluation and mitigation strategy (“REMS”) as part of a biologics license application (“BLA”) or after approval, which may impose further requirements or restrictions on the distribution or use of an approved product, such as limiting prescribing to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients who meet certain safe-use criteria and requiring treated patients to enroll in a registry.

Furthermore, the FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. While physicians may prescribe, in their independent professional medical judgment, products for off-label uses as the FDA does not regulate the behavior of physicians in their choice of drug treatments, the FDA does restrict a manufacturer’s communications on the subject of off-label use of their products. Companies may only share truthful and not misleading information that is otherwise consistent with a product’s FDA approved labeling. The FDA and other authorities actively enforce the laws and regulations prohibiting the promotion of off-label uses and a company that is found to have improperly promoted off-label uses may be subject to significant liability including, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined companies from engaging in off-label promotion. The FDA and other regulatory authorities have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.

Occurrence of any of the foregoing could have a material adverse effect on our business and results of operations. The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business.

Any product candidates for which we intend to seek approval as biologic products may face competition sooner than anticipated.

The Affordable Care Act includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 (“BPCIA”) which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until twelve years from the date on which the reference product was first licensed. During this twelve-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data from

adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The law is complex. The BPCIA could have a material adverse effect on the future commercial prospects for our biological products.

We believe that any of our future product candidates approved as a biological product under a BLA should qualify for the twelve-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to Congressional action or otherwise, or that the FDA will not consider our product candidates to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once approved, could be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products will depend on a number of marketplace and regulatory factors that are still developing.

Healthcare legislative reform measures may have a material adverse effect on our business and results of operations.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the Patient Protection and Affordable Care Act (the “ACA”) was enacted, which substantially changed the way healthcare is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. Among the provisions of the ACA, of greatest importance to the pharmaceutical and biotechnology industry are the following:

•

an annual, nondeductible fee on any entity that manufactures or imports certain specified branded prescription drugs and biologic agents apportioned among these entities according to their market share in some government healthcare programs;

•

an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13% of the average manufacturer price for most branded and generic drugs, respectively, and a cap on the total rebate amount for innovator drugs at 100% of the Average Manufacturer Price;

•

a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for certain drugs and biologics that are inhaled, infused, instilled, implanted or injected;

•

extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations;

•

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for individuals with income at or below 133% of the federal poverty level, thereby potentially increasing manufacturers’ Medicaid rebate liability;

•

a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (and 70% as of January 1, 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D;

•

expansion of the entities eligible for discounts under the Public Health program;

•

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research;

•

establishment of a Center for Medicare Innovation at the Centers for Medicare & Medicaid Services (“CMS”) to test innovative payment and service delivery models to lower Medicare and Medicaid spending; and

•

implementation of the federal physician payment transparency requirements, sometimes referred to as the “Physician Payments Sunshine Act.”

Since its enactment, there have been judicial, Congressional and executive challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will impact our business. In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted.

•

On August 2, 2011, the Budget Control Act of 2011 among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and will remain in effect through 2030.

•

On January 2, 2013, the American Taxpayer Relief Act of 2012 among other things, reduced Medicare payments to several providers, including hospitals and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

•

On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces.

•

On May 30, 2018, the Right to Try Act was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

•

On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020.

•

On December 20, 2019, former President Trump signed into law the Further Consolidated Appropriations Act (H.R. 1865), which repealed the Cadillac tax, the health insurance provider tax, and the medical device excise tax. It is impossible to determine whether similar taxes could be instated in the future.

Additionally, there has been heightened governmental scrutiny recently over the manner in which manufacturers set prices for their marketed products. For example, there have been several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional health care authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing, which could negatively affect our business, financial conditions, results of operation and prospects.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our current or future product candidates or additional pricing pressures. Further, it is possible that additional governmental action is taken in response to the COVID-19 pandemic. Any denial in coverage or reduction in reimbursement from Medicare or other government-funded programs may result in a similar denial or reduction in payments from private payors, which may prevent us from being able to generate sufficient revenue, attain profitability or commercialize our products. It is not clear how other future potential changes to the ACA will change the reimbursement model and market outlook for our current and future product candidates.

Failure to comply with health and data protection laws and regulations could lead to government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect our operating results and business.

We may collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect and share personal information, health information and other sensitive information to develop our products, to operate our business, for clinical trial purposes, for legal and marketing purposes, and for other business-related purposes.

We and any potential future collaborators, partners or service providers may be subject to federal, state and foreign data protection laws, regulations and regulatory guidance, the number and scope of which is changing, subject to differing applications and interpretations, and which may be inconsistent among jurisdictions, or in conflict with other rules, laws or contractual obligations. In the United States, numerous federal and state laws and regulations, including federal health information privacy laws, such as the Health Insurance Portability and Accountability Act (“HIPAA”), state data breach notification laws, state health information privacy laws and federal and state consumer protection laws, that govern the collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations of any future potential collaborators or service providers. In addition, we may obtain health information from third parties (including research institutions from which we obtain clinical trial data) that are subject to privacy and security requirements under HIPAA, or other privacy and data security laws. Depending on the facts and circumstances, we could be subject to civil or criminal penalties if we obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA, or if we otherwise violate applicable privacy and data security laws.

International data protection laws, including the EU’s General Data Protection Regulation (“GDPR”), may also apply to health-related and other personal information obtained outside of the United States. The GDPR went into effect on May 25, 2018, and imposes stringent data protection requirements for processing of personal data of individuals within the European Economic Area (“EEA”) as well as potential fines for noncompliant companies of up to the greater of €20 million or 4% of annual global revenue. The GDPR imposes numerous requirements for the collection, use and disclosure of personal data, including stringent requirements relating to consent and the information that must be shared with data subjects about how their personal information is used, the obligation to notify regulators and affected individuals of personal data breaches, extensive internal privacy governance obligations and obligations to honor expanded rights of individuals in relation to their personal information.

In addition, the GDPR places restrictions on cross-border data transfers. A decision by the Court of Justice of the European Union (“CJEU”) in 2020 invalidated the EU-U.S. Privacy Shield Framework, which was one of the primary mechanisms used by U.S. companies to import personal information from Europe in compliance with the GDPR’s cross-border data transfer restrictions, and raised questions about whether the European Commission’s Standard Contractual Clauses, one of the primary alternatives to the Privacy Shield, can lawfully be used for personal information transfers from Europe to the United States or most other countries. Similarly, the Swiss Federal Data Protection and Information Commissioner has opined that the Swiss-U.S. Privacy Shield is inadequate for transfers of data from Switzerland to the U.S. Furthermore, on June 4, 2021, the European

Commission issued new forms of standard contractual clauses for data transfers from controllers or processors in the EEA (or otherwise subject to the GDPR) to controllers or processors established outside the EEA (and not subject to the GDPR). The new forms of standard contractual clauses have replaced the standard contractual clauses that were adopted previously under the Data Protection Directive. We will be required to transition to the new forms of standard contractual clauses and doing so will require significant effort and cost. The new standard contractual clauses may also impact our business as companies based in Europe may be reluctant to utilize the new clauses to legitimize transfers of personal information to third countries given the burdensome requirements of transfer impact assessments and the substantial obligations that the new standard contractual clauses impose upon exporters. If we are investigated by a European data protection authority, we may face fines and other penalties. Any such investigation or charges by European data protection authorities could have a negative effect on our existing business and on our ability to attract and retain new clients or pharmaceutical partners. We may also experience hesitancy, reluctance, or refusal by European or multi-national clients or pharmaceutical partners to continue to use our products due to the potential risk exposure as a result of the current (and, in particular, future) data protection obligations imposed on them by certain data protection authorities in interpretation of current law, including the GDPR. Such clients or pharmaceutical partners may also view any alternative approaches to compliance as being too costly, too burdensome, too legally uncertain, or otherwise objectionable and therefore decide not to do business with us. Any of the foregoing could materially harm our business, prospects, financial condition, and results of operations.

The GDPR has increased our responsibilities and potential liability in relation to personal data processed subject to the GDPR, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. Companies now have to comply with the GDPR and also the United Kingdom GDPR (“UK GDPR”), which, together with the amended UK Data Protection Act 2018, retains the GDPR in UK national law. The UK GDPR mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (£17.5 million) or 4% of global turnover. In addition, on June 28, 2021, the European Commission adopted an adequacy decision in respect of transfers of personal data to the UK for a four-year period (until June 27, 2025). Similarly, the UK has determined that it considers all of the EEA to be adequate for the purposes of data protection. This ensures that data flows between the UK and the EEA remain unaffected. Compliance with the GDPR and applicable laws and regulations relating to privacy and data protection of EEA Member States and the UK is a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation and reputational harm in connection with our European activities. In addition, any failure by us (or our business partners who handle personal data) to comply with GDPR and applicable laws and regulations relating to privacy and data protection of EEA member states and the UK may result in regulators prohibiting our processing of the personal data of EEA data subjects, which could impact our operations and ability to develop our products and provide our services, including interrupting or ending EEA clinical trials.

In addition, states are constantly adopting new laws or amending existing laws, requiring attention to frequently changing regulatory requirements. For example, California enacted the California Consumer Privacy Act (the “CCPA”) on June 28, 2018, which took effect on January 1, 2020. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used by requiring covered companies to provide new disclosures to California consumers (as that term is broadly defined and can include any of our current or future employees who may be California residents) and provide such residents new ways to opt-out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches and statutory damages, which is expected to increase data breach class action litigation and result in significant exposure to costly legal judgments and settlements. Although the law includes limited exceptions for health-related information, including clinical trial data, such exceptions may not apply to all of our operations and processing activities. As we expand our operations and trials (both preclinical and clinical), the CCPA may increase our compliance costs and potential liability. Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent privacy legislation in the United States. In November 2020, California passed the California Privacy Rights Act (the “CPRA”) which amends and expands

the CCPA. The CPRA will impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. The CPRA has created additional uncertainty and may increase our cost of compliance. Other states are beginning to pass similar laws. In the event that we are subject to or affected by HIPAA, the GDPR, the CCPA, the CPRA or other domestic privacy and data protection laws, any liability from failure to comply with the requirements of these laws could adversely affect our financial condition.

Compliance with U.S. and international data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our ability to collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. Laws and regulations worldwide relating to privacy, data protection and cybersecurity are, and are likely to remain, uncertain for the foreseeable future. While we strive to comply with applicable laws and regulations relating to privacy, data protection and cybersecurity, external and internal privacy and security policies and contractual obligations relating to privacy, data protection and cybersecurity to the extent possible, we may at times fail to do so, or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance if our personnel, collaborators, partners or vendors do not comply with applicable laws and regulations relating to privacy, data protection and cybersecurity, external and internal privacy and security policies and contractual obligations relating to privacy, data protection and cybersecurity. Actual or perceived failure to comply with any laws and regulations relating to privacy, data protection or cybersecurity in the U.S. or foreign jurisdictions could result in government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect our operating results and business. Moreover, clinical trial subjects about whom we or our potential collaborators or service providers obtain information, as well as the providers who share this information with us, may contractually limit our ability to use and disclose the information. Claims that we have violated individuals’ privacy rights, failed to comply with applicable laws or regulations, or breached our contractual obligations, even if we are not found liable, could be expensive and time consuming to defend, result in regulatory actions and proceedings, in addition to private claims and litigation, and could result in adverse publicity that could harm our business.

We also are, or may be asserted to be, subject to the terms of our external and internal privacy and security policies, representations, certifications, publications and frameworks and contractual obligations to third parties related to privacy, data protection, information security and processing. Failure to comply or the perceived failure to comply with any of these, or if any of these policies or any of our representations, certifications, publications or frameworks are, in whole or part, found or perceived to be inaccurate, incomplete, deceptive, unfair or misrepresentative of our actual practices, could result in reputational harm, result in litigation, cause a material adverse impact to business operations or financial results and otherwise result in other material harm to our business.

If we or our existing or potential future collaborators, manufacturers or service providers fail to comply with healthcare laws and regulations, we or they could be subject to enforcement actions, which could affect our ability to develop, market and sell our product candidates and may harm our reputation.

Healthcare providers, physicians and third-party payors, among others, will play a primary role in the prescription and recommendation of any product candidates for which we obtain marketing approval. Our current and future arrangements with third-party payors, providers and customers, among others, may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute our product candidates for

which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations in the United States and other countries, include the following:

•

the federal Anti-Kickback Statute, which prohibits, among other things, a person or entity from knowingly and willfully soliciting, offering, paying, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease order, arranging for or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, by a federal healthcare program, such as Medicare or Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

federal civil and criminal false claims laws, including the federal False Claims Act, which provides for civil whistleblower or qui tam actions, and civil monetary penalties laws, that impose penalties against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items and services resulting from a referral made in violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act;

•

HIPAA, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”) and its implementing regulations, including the Final Omnibus Rule published in January 2013, which impose obligations on certain covered entity healthcare providers, health plans and healthcare clearinghouses as well as their business associates and their subcontractors that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information, and require notification to affected individuals and regulatory authorities of certain breaches of security of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, there may be additional federal, state, and non-U.S. laws which govern the privacy and security of health and other personal information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts;

•

the federal false statements statute, which prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services;

•

the federal physician payment transparency requirements, sometimes referred to as the “Sunshine Act” under the Affordable Care Act, require certain manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to report to the CMS information related to transfers of value made to physicians (currently defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests of such physicians and their immediate family members. Effective January 1, 2022, these reporting obligations extend to include payments and transfers of value, made during the previous year to certain non-physician providers, including physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiologist assistants and certified nurse midwives; and

•

analogous local, state and foreign laws and regulations, such as state anti-kickback and false claims laws that may apply to healthcare items or services reimbursed by third party payors, including private insurers, local, state and foreign transparency laws that require manufacturers to report information related to payments and transfers of value to other healthcare providers and healthcare entities, marketing expenditures, or drug pricing, state laws that require pharmaceutical companies to register certain employees engaged in marketing activities in the location and comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, and state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Ensuring that our future business arrangements with third parties comply with applicable healthcare laws and regulations could involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including our relationships with physicians and other healthcare providers, some of whom are compensated in the form of stock options for consulting services provided, may not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any such requirements, we may be subject to penalties, including criminal and significant civil monetary penalties, damages, fines, imprisonment, disgorgement, contractual damages, reputational harm, exclusion from participation in government healthcare programs, integrity obligations, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, private qui tam actions brought by individual whistleblowers in the name of the government, refusal to allow us to enter into supply contracts, including government contracts, additional reporting requirements and oversight if subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. Although effective compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, these risks cannot be entirely eliminated. Any action against us for an alleged or suspected violation could cause us to incur significant legal expenses and could divert our management’s attention from the operation of our business, even if our defense is successful. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the above occur, our ability to operate our business and our results of operations could be adversely affected. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us in terms of money, time and resources.

If we fail to comply with U.S. and foreign regulatory requirements, regulatory authorities could limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business.

Even if we receive marketing and commercialization approval of a product candidate, we will be subject to continuing regulatory requirements, including in relation to adverse patient experiences with the product and clinical results that are reported after a product is made commercially available, both in the United States and any foreign jurisdiction in which we seek regulatory approval. The FDA and other regulatory authorities have significant post- market authority, including the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate safety risks related to the use of a product or to require withdrawal of the product candidate from the market. The FDA and other regulatory authorities also have the authority to require a REMS after approval, which may impose further requirements or restrictions on the distribution or use of an approved drug or therapeutic biologic. The manufacturer and manufacturing facilities we use to make a future product, if any, will also be subject to periodic review and inspection by the FDA and other regulatory authorities, including for continued compliance with cGMP and cGTP requirements. The discovery of any new or previously unknown problems with our third-party manufacturers, manufacturing processes or facilities may result in restrictions on the product candidate, manufacturer or facility, including withdrawal of the product candidate from the market. We intend to rely on

third-party manufacturers and we will not have control over compliance with applicable rules and regulations by such manufacturers. Any product promotion and advertising will also be subject to regulatory requirements and continuing regulatory review. If we or our existing or future collaborators, manufacturers or service providers fail to comply with applicable continuing regulatory requirements in the U.S. or foreign jurisdictions in which we seek to market our products, we or they may be subject to, among other things, fines, warning letters, holds on clinical trials, delay of approval or refusal by the FDA or other regulatory authorities to approve pending applications or supplements to approved applications, suspension or withdrawal of regulatory approval, product recalls and seizures, administrative detention of products, refusal to permit the import or export of products, operating restrictions, injunction, civil penalties and criminal prosecution.

In the United States and markets in other countries, patients generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. Further, due to the COVID-19 pandemic, millions of individuals have lost/will be losing employer-based insurance coverage, which may adversely affect our ability to commercialize our products. It is unclear what effect, if any, the American Rescue Plan will have on the number of covered individuals.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products and coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the United States, the principal decisions about reimbursement for new medicines are typically made by the CMS, an agency within the U.S. Department of Health and Human Services. CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree.

Our ability to commercialize any products successfully will depend, in part, on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from third-party payors, such as government authorities, private health insurers and health maintenance organizations. Patients who are prescribed medications for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. Coverage and adequate reimbursement from government healthcare programs, such as Medicare and Medicaid, and private health insurers are critical to new product acceptance. Patients are unlikely to use our future products, if any, unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost. Obtaining coverage and adequate reimbursement for our product candidates may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Similarly, because our product candidates are physician-administered, separate reimbursement for the product itself may or may not be available. Instead, the administering physician may or may not be reimbursed for providing the treatment or procedure in which our product is used.

Cost-containment is a priority in the U.S. healthcare industry and elsewhere. As a result, government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Third-party payors also may request additional clinical evidence beyond the data required to obtain marketing approval, requiring a company to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of its product. Commercial third-party payors often rely upon Medicare coverage policy and payment limitations in setting their reimbursement rates, but also have their own methods and approval process apart from Medicare determinations. Therefore, coverage and reimbursement for pharmaceutical products in the U.S. can differ significantly from payor to payor. We cannot be sure that

coverage and adequate reimbursement will be available for any product that we commercialize and, if reimbursement is available, that the level of reimbursement will be adequate. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. If coverage and reimbursement are not available or are available only at limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.

Additionally, the regulations that govern regulatory approvals, pricing and reimbursement for new drugs and therapeutic biologics vary widely from country to country. Some countries require approval of the sale price of a drug or therapeutic biologic before it can be marketed. In many countries, the pricing review period begins after marketing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain regulatory approval.

We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal or civil liability and harm our business.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”), the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and possibly other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We interact with officials and employees of government agencies and government-affiliated hospitals, universities and other organizations. In addition, we may engage third-party intermediaries to promote our clinical research activities abroad or to obtain necessary permits, licenses and other regulatory approvals. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, collaborators and agents, even if we do not explicitly authorize or have actual knowledge of such activities.

In connection with the Business Combination, New Senti will adopt a Code of Business Conduct and Ethics that will be effective following the closing of the Business Combination and we expect to prepare and implement policies and procedures to ensure compliance with such code. The Code of Business Conduct and Ethics mandates compliance with the FCPA and other anti-corruption laws applicable to our business throughout the world. However, we cannot assure you that our employees and third-party intermediaries will comply with this code or such anti-corruption laws. Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas, investigations or other enforcement actions are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs and administrative burdens.

General Risk Factors

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory and policy changes, the FDA’s ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time necessary for new drugs and biologics or modifications to approved drugs and biologics to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities.

Since March 2020 when foreign and domestic inspections of facilities were largely placed on hold, the FDA has been working to resume routine surveillance, bioresearch monitoring and pre-approval inspections on a prioritized basis. Since April 2021, the FDA has conducted limited inspections and has employed remote interactive evaluations, using risk management methods, to meet user fee commitments and goal dates. Ongoing travel restrictions and other uncertainties continue to impact oversight operations both domestic and abroad and it is unclear when standard operational levels will resume. The FDA is continuing to complete mission-critical work, prioritize other higher-tiered inspectional needs (e.g., for-cause inspections), and carry out surveillance inspections using risk-based approaches for evaluating public health. Should FDA determine that an inspection is necessary for approval and an inspection cannot be completed during the review cycle due to restrictions on travel, and the FDA does not determine a remote interactive evaluation to be adequate, the agency has stated that it generally intends to issue, depending on the circumstances, a complete response letter or defer action on the application until an inspection can be completed. During the COVID-19 public health emergency, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. Regulatory authorities outside the U.S. may adopt similar restrictions or other policy measures in response to the ongoing COVID-19 pandemic and may experience delays in their regulatory activities.

We or the third parties upon whom we depend may be adversely affected by natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our current operations are located in the San Francisco Bay Area. Any unplanned event, such as earthquake, flood, fire, explosion, extreme weather condition, medical epidemics, including any potential effects from the current global spread of COVID-19, power shortage, telecommunication failure or other natural or man-made accidents or incidents that result in us being unable to fully utilize our facilities, or the manufacturing facilities of our third-party contract manufacturers, may have a material adverse effect on our ability to operate our business, particularly on a daily basis and have significant negative consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development of our product candidates or interruption of our business operations. Natural disasters or pandemics such as the COVID-19 outbreak could further disrupt our operations and have a material adverse effect on our business, financial condition, results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as our research facilities or the manufacturing facilities of our third-party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. The disaster recovery and business continuity plans we

have in place may prove inadequate in the event of a serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which could have a material adverse effect on our business. As part of our risk management policy, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot assure our investors that the amounts of insurance will be sufficient to satisfy any damages and losses. If our facilities or the manufacturing facilities of our third-party contract manufacturers are unable to operate because of an accident or incident or for any other reason, even for a short period of time, any or all of our research and development programs may be harmed. Any business interruption may have a material adverse effect on our business, financial condition, results of operations and prospects.

Our quarterly operating results may fluctuate significantly or may fall below the expectations of investors or securities analysts, each of which may cause our stock price to fluctuate or decline.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors, including:

•

variations in the level of expense related to the ongoing development of our product candidates or future development programs;

•

results of preclinical studies and clinical trials, or the addition or termination of preclinical studies and clinical trials or funding support by us or potential future collaborators;

•

our execution of any collaboration, licensing or similar arrangements, and the timing of payments we may make or receive under potential future arrangements or the termination or modification of any of our existing or potential future collaboration, licensing or similar arrangements;

•

any intellectual property infringement, misappropriation or violation lawsuit or opposition, interference or cancellation proceeding in which we may become involved;

•

additions and departures of key personnel;

•

strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;

•

if any of our product candidates receives regulatory approval, the terms of such approval and market acceptance and demand for such product candidates;

•

regulatory developments affecting our product candidates or those of our competitors; and

•

changes in general market and economic conditions.

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially. We believe that quarterly comparisons of our financial results are not necessarily meaningful and should not be relied upon as an indication of our future performance.

We may be subject to claims that our employees, consultants, or independent contractors have wrongfully used or disclosed confidential information of third parties.

We have received confidential and proprietary information from third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants, or independent contractors have inadvertently or otherwise used or disclosed confidential information of these third parties or our employees’ former employers, or that we caused an employee to breach the terms of his or her non-competition or non-solicitation agreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees. If our

defenses to these claims fail, in addition to requiring us to pay monetary damages, a court could prohibit us from using technologies or features that are essential to our product candidates, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers. Moreover, any such litigation or the threat thereof may adversely affect our reputation, our ability to form strategic alliances or sublicense our rights to collaborators, engage with scientific advisors or hire employees or consultants, each of which would have an adverse effect on our business, results of operations, financial condition and prospects. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

Risks Related to New Senti and the New Senti Common Stock Following the Business Combination

The New Senti stock price may be volatile.

The New Senti stock price is likely to be volatile. The market price for New Senti Common Stock may be influenced by many factors, including the other risks described in this section of the proxy statement/prospectus entitled “Risk Factors” and the following:

•

New Senti’s ability to advance its current or potential future product candidates into the clinic;

•

results of preclinical studies for New Senti’s current or potential future product candidates, or those of its competitors or potential future collaborators;

•

the impact of the ongoing COVID-19 pandemic on New Senti’s business;

•

regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to New Senti’s future products;

•

New Senti’s ability to successfully construct and operate its planned cGMP and cGTP facility;

•

the success of competitive products or technologies;

•

introductions and announcements of new products by New Senti, its future commercialization collaborators, or its competitors, and the timing of these introductions or announcements;

•

actions taken by regulatory authorities with respect to New Senti future products, clinical trials, manufacturing process or sales and marketing terms;

•

actual or anticipated variations in New Senti’s financial results or those of companies that are perceived to be similar to New Senti;

•

the success of New Senti’s efforts to acquire or in-license additional technologies, products or product candidates;

•

developments concerning any future collaborations, including, but not limited to, those with any sources of manufacturing supply and future commercialization collaborators;

•

market conditions in the pharmaceutical and biotechnology sectors;

•

market conditions and sentiment involving companies that have recently completed a business combination with a special purpose acquisition company (“SPAC”);

•

announcements by New Senti or its competitors of significant acquisitions, strategic alliances, joint ventures or capital commitments;

•

developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and New Senti’s ability to obtain patent protection for its products;

•

New Senti’s ability or inability to raise additional capital and the terms on which it is raised;

•

the recruitment or departure of key personnel;

•

changes in the structure of healthcare payment systems;

•

actual or anticipated changes in earnings estimates or changes in stock market analyst recommendations regarding New Senti Common Stock, other comparable companies or the industry generally;

•

New Senti’s failure or the failure of its competitors to meet analysts’ projections or guidance that New Senti or its competitors may give to the market;

•

fluctuations in the valuation of companies perceived by investors to be comparable to New Senti;

•

announcement and expectation of additional financing efforts;

•

speculation in the press or investment community;

•

trading volume of New Senti Common Stock;

•

sales of New Senti Common Stock by New Senti or its stockholders;

•

the concentrated ownership of New Senti Common Stock;

•

changes in accounting principles;

•

terrorist acts, acts of war or periods of widespread civil unrest;

•

natural disasters, public health crises and other calamities; and

•

general economic, industry and market conditions.

In addition, the stock markets in general, and the markets for SPAC post-business combination businesses, pharmaceutical, biopharmaceutical and biotechnology stocks in particular, have experienced extreme volatility, including since the public announcement of the Business Combination Agreement in December 2021. This volatility can often be unrelated to the operating performance of the underlying business. These broad market and industry factors may seriously harm the market price of New Senti Common Stock, regardless of New Senti’s operating performance.

New Senti may incur significant costs from class action litigation due to the expected stock volatility.

New Senti’s stock price may fluctuate for many reasons, including as a result of public announcements regarding the progress of development efforts for New Senti’s platform and product candidates, the development efforts of future collaborators or competitors, the addition or departure of key personnel, variations in quarterly operating results and changes in market valuations of biopharmaceutical and biotechnology companies. This risk is especially relevant to New Senti because biopharmaceutical and biotechnology companies have experienced significant stock price volatility in recent years, including since the public announcement of the Business Combination Agreement in December 2021. In addition, recently there has been significant stock price volatility involving the shares of companies that have recently completed a business combination with a SPAC. When the market price of a stock has been volatile as New Senti’s stock price may be, holders of that stock have occasionally brought securities class action litigation against the company that issued the stock. Additionally, there has recently been a general increase in litigation against companies that have recently completed a business combination with a SPAC alleging fraud and other claims based on inaccurate or misleading disclosures. If any New Senti stockholders were to bring a lawsuit of this type against New Senti, even if the lawsuit is without merit, New Senti could incur substantial costs defending the lawsuit. The lawsuit could also divert the time and attention of management.

New Senti will be an “emerging growth company” and it cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make the New Senti Common Stock less attractive to investors and may make it more difficult to compare performance with other public companies.

New Senti will be an emerging growth company as defined in the JOBS Act, and it intends to take advantage of certain exemptions from various reporting requirements that are applicable to other public

companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Investors may find the New Senti Common Stock less attractive because New Senti will continue to rely on these exemptions. If some investors find the New Senti Common Stock less attractive as a result, there may be a less active trading market for their common stock, and the stock price may be more volatile.

An emerging growth company may elect to delay the adoption of new or revised accounting standards. With DYNS making this election, Section 102(b)(2) of the JOBS Act allows New Senti to delay adoption of new or revised accounting standards until those standards apply to non-public business entities. As a result, the financial statements contained in this proxy statement/prospectus and those that New Senti will file in the future may not be comparable to companies that comply with public business entities revised accounting standards effective dates.

Future sales and issuances of New Senti common Stock or rights to purchase common stock could result in additional dilution of the percentage ownership of New Senti stockholders and could cause the New Senti stock price to fall.

Significant additional capital will be needed in the future to continue New Senti’s planned operations, including further development of New Senti’s gene circuit platform, preparing IND or equivalent filings, conducting preclinical studies and clinical trials, commercialization efforts, expanded research and development activities and costs associated with operating a public company. To raise capital, New Senti may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner as determined from time to time. If New Senti sells common stock, convertible securities or other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to existing stockholders, and new investors could gain rights, preferences and privileges senior to the holders of New Senti Common Stock.

Pursuant to the Incentive Plan, the New Senti Board or compensation committee is authorized to grant stock options to our employees, directors and consultants. Initially, the maximum aggregate number of shares of New Senti Common Stock that may be issued pursuant to stock awards under the Incentive Plan is 22% of the aggregate number of shares of New Senti Common Stock issued and outstanding immediately after the Closing, less any New Senti Common Stock the subject of Closing Option Awards (as defined in the Business Combination Agreement). Based on the assumed exchange ratio of 0.1955 described herein, the number of shares authorized for issuance under the Incentive Plan upon the Closing is expected to be approximately 4,040,000 shares of New Senti Common Stock (assuming no redemptions of Public Shares from the Trust Account), but the exact number will not be known until the Business Combination is consummated. Additionally, the number of shares of New Senti Common Stock reserved for issuance under the Incentive Plan will automatically increase on January 1 of each year, beginning on January 1, 2023 and continuing through and including January 1, 2032, by 5% of the total number of shares of New Senti Common Stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the New Senti Board. Unless the New Senti Board elects not to increase the number of shares available for future grant each year, New Senti stockholders may experience additional dilution, which could cause the New Senti stock price to fall.

New Senti’s issuance of additional shares of common stock or other equity securities of equal or senior rank would, all else being equal, have the following effects:

•

DYNS’s existing stockholders’ proportionate ownership interest in New Senti would decrease;

•

the amount of cash available per share, including for payment of dividends in the future, may decrease;

•

the relative voting strength of each previously outstanding share of common stock would be diminished; and

•

the market price of shares of New Senti Common Stock may decline.

New Senti’s disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

New Senti must design its disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make a required related party transaction disclosure. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

Reports published by analysts, including projections in those reports that differ from New Senti’s actual results, could adversely affect the price and trading volume of New Senti Common Stock.

DYNS currently expects that securities research analysts will establish and publish their own periodic financial projections for the business of New Senti. These projections may vary widely and may not accurately predict the results New Senti actually achieves. New Senti’s stock price may decline if its actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on New Senti downgrades its stock or publishes inaccurate or unfavorable research about its business, New Senti’s stock price could decline. If one or more of these analysts ceases coverage of New Senti or fails to publish reports on New Senti regularly, its stock price or trading volume could decline. While DYNS expects research analyst coverage following the Business Combination, if no analysts commence coverage of New Senti, the trading price and volume for New Senti Common Stock could be adversely affected.

New Senti’s actual financial position and results of operations may differ materially from the unaudited pro forma condensed combined financial information included in this proxy statement/prospectus, which may not be indicative of what New Senti’s actual financial position or results of operations would have been.

The unaudited pro forma condensed combined financial information in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what New Senti’s actual financial position or results of operations would have been had the Business Combination been completed on the dates indicated. See the section titled “Unaudited Pro Forma Condensed Combined Financial Information” for more information.

The obligations associated with being a public company will involve significant expenses and will require significant resources and management attention, which may divert from New Senti’s business operations.

As a public company, New Senti will become subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act. The Exchange Act requires the filing of annual, quarterly and current reports with respect to a public company’s business and financial condition. The Sarbanes-Oxley Act requires, among other things, that a public company establish and maintain effective internal control over financial reporting. As a result, New Senti will incur significant legal, accounting and other expenses that Senti did not previously incur. New Senti’s entire management team and many of its other employees will need to devote substantial time to compliance, and may not effectively or efficiently manage its transition into a public company.

These rules and regulations will result in New Senti incurring substantial legal and financial compliance costs and will make some activities more time-consuming and costly. For example, these rules and regulations will likely make it more difficult and more expensive for New Senti to obtain director and officer liability insurance, and it may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be difficult for New Senti to attract and retain qualified people to serve on its board of directors, its board committees or as executive officers.

Provisions in New Senti’s proposed second amended and restated certificate of incorporation (the Proposed Charter), New Senti’s proposed amended and restated bylaws and Delaware law may have anti-takeover effects that could discourage an acquisition of New Senti by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management, which could depress the trading price of New Senti Common Stock.

New Senti’s proposed second amended and restated certificate of incorporation (the Proposed Charter), proposed amended and restated bylaws and Delaware law contain provisions that may have the effect of discouraging, delaying or preventing a change in control of us or changes in our management that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. New Senti’s proposed second amended and restated certificate of incorporation (the Proposed Charter) and proposed amended and restated bylaws include provisions that:

•

authorize “blank check” preferred stock, which could be issued by our board of directors without stockholder approval and may contain voting, liquidation, dividend and other rights superior to our common stock;

•

create a classified board of directors whose members serve staggered three-year terms;

•

specify that special meetings of our stockholders can be called only by our board of directors;

•

prohibit stockholder action by written consent;

•

establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our board of directors;

•

specify that no stockholder is permitted to cumulate votes at any election of directors;

•

expressly authorize our board of directors to make, alter, amend or repeal our proposed amended and restated bylaws; and

•

require supermajority votes of the holders of our common stock to amend specified provisions of our proposed second amended and restated certificate of incorporation (the Proposed Charter) and proposed amended and restated bylaws.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management. These provisions could also limit the price that investors might be willing to pay in the future for shares of New Senti Common Stock, thereby depressing the market price of New Senti Common Stock.

In addition, because we are incorporated in the State of Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Any provision of New Senti’s proposed second amended and restated certificate of incorporation (the Proposed Charter), amended and restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of New Senti Common Stock, and could also affect the price that some investors are willing to pay for New Senti Common Stock.

New Senti’s proposed amended and restated bylaws designate the Court of Chancery of the State of Delaware as the exclusive forum for certain state law litigation that may be initiated by our stockholders and the U.S. federal district courts as the exclusive forum for certain securities law actions, which could limit our stockholders’ ability to litigate disputes with us in a different judicial forum and increase the costs for our stockholders to pursue certain claims against us.

Pursuant to New Senti’s proposed amended and restated bylaws, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or employees to us or our stockholders; (iii) any action asserting a claim arising pursuant to any provision of the General Corporation Law of the State of Delaware, our proposed second amended and restated certificate of incorporation (the Proposed Charter) or our proposed amended and restated bylaws (including their interpretation, validity or enforceability); or (iv) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum provision will not apply to any causes of action arising under the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Stockholders cannot waive compliance with the Securities Act, the Exchange Act or any other federal securities laws or the rules and regulations thereunder. Unless we consent in writing to the selection of an alternate forum, the United States federal district courts shall be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. In addition, our proposed amended and restated bylaws provide that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to these exclusive forum provisions. The forum selection provisions in our proposed amended and restated bylaws may limit our stockholders’ ability to litigate disputes with us in a judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits against us and our directors, officers and employees, even though an action, if successful, might benefit our stockholders. In addition, these forum selection provisions may impose additional litigation costs for stockholders who determine to pursue any such lawsuits against us.

Redemptions of Public Shares by Public Stockholders may affect the market price of New Senti Common Stock

Redemptions of Public Shares by Public Stockholders may affect the market price of New Senti Common Stock, but it is not possible to predict or quantify what the impact will be on the market price at any given level of redemptions. For example, as redemptions go up, it is possible that the market may view this as a sign of a lack of confidence in the value of New Senti Common Stock. In addition, as the level of redemptions rise, stockholders may become increasingly concerned about New Senti’s cash position and/or the efficiency of its capital structure. Also, as redemptions go up, the remaining shares of New Senti Common Stock will be more significantly impacted by the resulting increasing dilutive effect of any conversion or exercise of instruments convertible into or exercisable for New Senti Common Stock, such as the options to purchase New Senti Common Stock which will be outstanding following Closing, and any issuance of shares of New Senti Common Stock in respect of the Contingency Consideration. It is not possible to predict or quantify the impact a given level of redemptions will have on the market price of shares of New Senti Common Stock. In all cases, the impact will be based at least in part on market perceptions and, in some cases, the impact will also be affected by other market factors such as, in the case of potential dilution from instruments convertible into or exercisable for shares of New Senti Common Stock, how far out of the money the dilutive instruments are at the time, prevailing interest rates and the volatility of shares of New Senti Common Stock at the relevant time.

Risks Related to the Business Combination and Redemptions

DYNS will incur significant transaction and transition costs in connection with the Business Combination.

DYNS has incurred and expects to incur significant, non-recurring costs in connection with consummating the Business Combination and operating as a public company following the consummation of the Business

Combination. DYNS may also incur additional costs to retain key employees. Certain transaction expenses incurred in connection with the Business Combination, including all legal, accounting, consulting, investment banking and other fees, expenses and costs, will be paid by New Senti at or following the closing of the Business Combination.

DYNS will not have any right after the Closing to make damage claims against Senti or Senti’s stockholders for the breach of representations, warranties or covenants made by Senti in the Business Combination Agreement.

The Business Combination Agreement provides that all of the representations, warranties and covenants of the parties contained therein shall not survive the Closing, except for a limited number of representations and warranties and those covenants that by their terms apply or are to be performed in whole or in part after the Closing, and then only with respect to breaches occurring after Closing. Accordingly, there are no remedies available to the parties with respect to any breach of the representations, warranties, covenants or agreements of the parties to the Business Combination Agreement after the Closing of the Business Combination, except for those representations and warranties that do survive and the covenants to be performed in whole or in part after the Closing. As a result, DYNS will have no remedy available to it if the Business Combination is consummated and it is later revealed that there was a breach of any of the representations, warranties and covenants made by Senti in the Business Combination Agreement (subject to the limited exceptions noted above).

Subsequent to the Closing, New Senti may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and the price of shares of New Senti Common Stock, which could cause you to lose some or all of your investment.

Although DYNS has conducted due diligence on Senti, DYNS cannot assure you that this diligence revealed all material issues that may be present in Senti’s business, that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of DYNS’s and Senti’s control will not later arise. As a result, after the Closing, New Senti may be forced to later write-down or write-off assets, restructure

its operations, or incur impairment or other charges that could result in losses. Even if DYNS’s due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with DYNS’s preliminary risk analysis. Even though these charges may be non-cash items and may not have an immediate impact on New Senti’s liquidity, the fact that New Senti may incur charges of this nature could contribute to negative market perceptions about the Combined Company’s securities. In addition, charges of this nature may cause New Senti to be unable to obtain future financing on favorable terms or at all. Accordingly, any DYNS stockholder who chooses to remain a stockholder of the Combined Company following the Business Combination could suffer a reduction in the value of their shares of New Senti Common Stock. Such stockholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by DYNS’s officers or directors of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the proxy solicitation relating to the Business Combination contained an actionable material misstatement or material omission.

The Sponsor and DYNS’s officers and directors and/or their affiliates beneficially own or have a pecuniary interest in Founder Shares and additional securities that they purchased in the Concurrent Private Placement (Private Placement Shares). The holders have no redemption rights with respect to these securities in the event a business combination is not effected in the required time period. Therefore, if the Business Combination with Senti or

another business combination is not approved within the required time period, such securities held by such persons will be worthless. Based upon the closing price of Class A Common Stock of $9.94 per share on Nasdaq on the Record Date, such securities had an implied aggregate market value, assuming the Business Combination is consummated, of approximately $64.3 million. Accordingly, the Sponsor (and DYNS’s officers and directors and/or their affiliates who are members of the Sponsor) may be incentivized to complete the Business Combination, or an alternative business combination, with a less favorable target company or on terms less favorable to stockholders than they would otherwise recommend or approve, as the case may be, rather than allow DYNS to wind up having failed to consummate a business combination and lose their entire investment. Furthermore, the Sponsor and DYNS’s officers and directors and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on DYNS’s behalf, such as identifying and investigating possible business targets and business combinations. Any such expenses will be repaid upon completion of the Business Combination with Senti. As of the date of this proxy statement/prospectus, no such reimbursable expenses have been incurred. If any such expenses are incurred, however, if DYNS fails to consummate the Business Combination, they will not have any claim against the Trust Account for repayment or reimbursement. Accordingly, DYNS may not be able to repay or reimburse these amounts if the Business Combination is not completed. See the section entitled “Summary of the Proxy Statement/Prospectus—Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination.”

These financial interests may have influenced the decision of DYNS’s directors to approve the Business Combination with Senti and to continue to pursue such Business Combination. In considering the recommendations of DYNS’s Board to vote for the Business Combination Proposal and other Proposals, DYNS’s stockholders should consider these interests.

The Public Stockholders will experience immediate dilution as a consequence of the issuance of Class A Common Stock as consideration in the Business Combination and in the PIPE Investment.

In accordance with the terms and subject to the conditions of the Business Combination Agreement, at the Effective Time, (i) each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share); (ii) each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (A) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio (rounded down to the nearest whole share); and (iii) each outstanding Senti option will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent). In addition, holders of shares of Senti common stock and Senti preferred stock may also be eligible to receive Contingent Consideration of up to an aggregate of 2,000,000 shares of Class A Common Stock (which would be shares of New Senti Common Stock) based on the share price performance of New Senti Common Stock following Closing or, in certain circumstances, upon a change in control of New Senti. Finally, in connection with the PIPE Investment, an aggregate of 6,680,000 shares of Class A Common Stock will be issued. The issuance of additional Class A Common Stock will significantly dilute the equity interests of existing holders of DYNS securities, and may adversely affect prevailing market prices for the Class A Common Stock.

The exercise of DYNS’s directors’ and officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination Agreement or waivers of conditions are appropriate and in the best interests of DYNS’s stockholders.

In the period leading up to the Closing, events may occur that, pursuant to the Business Combination Agreement, would require DYNS to agree to amend the Business Combination Agreement, to consent to certain

actions taken by Senti or to waive rights that DYNS is entitled to under the Business Combination Agreement. Such events could arise because of changes in the course of Senti’s business, a request by Senti to undertake actions that would otherwise be prohibited by the terms of the Business Combination Agreement or the occurrence of other events that would have a material adverse effect on Senti’s business and would entitle DYNS to terminate the Business Combination Agreement. In any of such circumstances, it would be at DYNS’s discretion, acting through its Board, to grant its consent or waive those rights. The existence of the financial and personal interests of the directors described in the preceding risk factors may result in a conflict of interest on the part of one or more of the directors between what he, she or they may believe is best for DYNS and what he, she or they may believe is best for himself, herself or themselves in determining whether or not to take the requested action. As of the date of this proxy statement/prospectus, DYNS does not believe there will be any material changes or waivers that DYNS’s directors and officers would be likely to make after the mailing of this proxy statement/prospectus. DYNS will circulate a supplemental or amended proxy statement/prospectus if changes to the terms of the Business Combination that would have a material impact on its stockholders are required prior to the vote on the Business Combination Proposal.

Under the terms of the Current Charter, DYNS must complete the Business Combination with Senti or another business combination by May 28, 2023 (or such later date as may be approved by DYNS stockholders in an amendment to its Current Charter), or DYNS must cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Public Shares for cash and, subject to the approval of its remaining stockholders and its Board, dissolving and liquidating. In such event, third parties may bring claims against DYNS. Although DYNS seeks waiver agreements from certain vendors and service providers it has engaged and owes money to, and the prospective target businesses it has negotiated with, whereby such parties will waive any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, there is no guarantee that vendors, regardless of whether they execute such waivers, will not seek recourse against the Trust Account notwithstanding such agreements. Furthermore, there is no guarantee that a court will uphold the validity of such agreements. Accordingly, the proceeds held in the Trust Account could be subject to claims which could take priority over those of the Public Stockholders. If DYNS is unable to complete a business combination within the required time period, the Sponsor has agreed that it will be liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by DYNS for services rendered or contracted for or products sold to DYNS. However, the Sponsor may not be able to meet such obligation as its only assets are securities of DYNS. Therefore, the per-share distribution from the Trust Account in such a situation may be less than $10.00 due to such claims.

Additionally, if DYNS is forced to file a bankruptcy case or an involuntary bankruptcy case is filed against it which is not dismissed, or if DYNS otherwise enters compulsory or court supervised liquidation, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in its bankruptcy estate and subject to the claims of third parties with priority over the claims of DYNS’s stockholders. To the extent any bankruptcy claims deplete the Trust Account, DYNS may not be able to return to its Public Stockholders at least $10.00 per share of DYNS Common Stock.

DYNS’s stockholders may be held liable for claims by third parties against DYNS to the extent of distributions received by them.

If DYNS is unable to complete the Business Combination with Senti or another business combination within the required time period, DYNS will (i) cease all operations except for the purpose of winding up, (ii) as

promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. DYNS cannot assure you that it will properly assess all claims that may potentially be brought against DYNS. As such, DYNS’s stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of its stockholders may extend well beyond the third anniversary of the date of distribution. Accordingly, DYNS cannot assure you that third parties will not seek to recover from its stockholders amounts owed to them by DYNS.

If DYNS file a bankruptcy petition or an involuntary bankruptcy petition is filed against DYNS that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our stockholders. To the extent any bankruptcy claims deplete the Trust Account, DYNS cannot provide any assurance that DYNS will be able to return $10.00 per share to our Public Stockholders. Additionally, if DYNS file a bankruptcy petition or an involuntary bankruptcy petition is filed against DYNS that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by DYNS’s stockholders. Furthermore, DYNS’s Board may be viewed as having breached its fiduciary duty to DYNS’s creditors and/or may have acted in bad faith, thereby exposing itself and our company to claims of punitive damages, by paying Public Stockholders from the Trust Account prior to addressing the claims of creditors. DYNS cannot provide any assurance that claims will not be brought against DYNS for these reasons.

Activities taken by existing DYNS stockholders to increase the likelihood of approval of the Business Combination Proposal and the other Proposals could have a depressive effect on DYNS Common Stock.

At any time prior to the Special Meeting, during a period when they are not then aware of any material nonpublic information regarding DYNS or its securities, the Sponsor, DYNS’s officers, directors and stockholders from prior to the Initial Public Offering, Senti or Senti’s stockholders and/or their respective affiliates may enter into transactions with such investors and others to provide them with incentives to acquire DYNS Common Stock or vote their shares in favor of the Business Combination Proposal. The purpose of such transactions would be to increase the likelihood of satisfaction of the requirements to consummate the Business Combination where it appears that such requirements would otherwise not be met. Entering into any such arrangements may have a depressive effect on DYNS Common Stock. For example, as a result of these arrangements, an investor or holder may have the ability to effectively purchase shares at a price lower than market and may therefore be more likely to sell the shares he, she or it owns, either prior to or immediately after the Special Meeting.

If the Adjournment Proposal is not approved, and an insufficient number of votes have been obtained to authorize the consummation of the Business Combination, the Board will not have the ability to adjourn the Special Meeting to a later date in order to solicit further votes, and, therefore, the Business Combination will not be approved.

Neither the Board nor any committee thereof obtained a third-party financial opinion in determining whether or not to pursue the Business Combination.

Neither the board of directors of DYNS nor any committee thereof obtained an opinion from an independent investment banking or accounting firm that the price that DYNS is paying for Senti is fair to DYNS from a financial point of view. Neither the board of directors of DYNS nor any committee thereof obtained a third-party valuation in connection with the Business Combination. In analyzing the Business Combination, the board of directors of DYNS and management conducted due diligence on Senti and researched the industry in which Senti operates. The board of directors of DYNS reviewed, among other things, financial due diligence materials prepared by Senti, including, financial and market data information on selected comparable companies, the implied purchase price multiple of Senti and the financial terms set forth in the Business Combination Agreement, and concluded that the Business Combination was in the best interest of its stockholders. Accordingly, investors will be relying solely on the judgment of the board of directors and management of DYNS in valuing Senti, and the board of directors and management of DYNS may not have properly valued such businesses. The lack of a third-party valuation may also lead an increased number of stockholders to vote against the Business Combination or demand redemption of their shares, which could potentially impact our ability to consummate the Business Combination.

We are dependent upon our current executive officers and directors and their loss could adversely affect our ability to operate.

Our operations are dependent upon a relatively small group of individuals and, in particular, our executive officers and directors. We believe that our success depends on the continued service of our officers and directors, at least until we have completed the Business Combination.

Certain of our existing stockholders have agreed to vote in favor of the Business Combination, regardless of how our Public Stockholders vote.

Certain of our existing shareholders, including the Sponsor and our directors and officers, have agreed to vote the Founder Shares and Private Placement Shares, as well as any Public Shares purchased during or after the IPO, in favor of the Business Combination.

At the time of the Special Meeting, we expect that the Sponsor and our directors and officers will collectively own approximately 21.9% of the outstanding DYNS Common Stock. Accordingly, it is more likely that the necessary stockholder approval will be received than would be the case if such persons agreed to vote their shares in accordance with the majority of the votes cast by our Public Stockholders.

Our actual financial position and results of operations may differ materially from the unaudited pro forma financial information included in this proxy statement/prospectus.

The unaudited pro forma condensed combined financial information in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what our actual financial position or results of operations would have been had the Business Combination been completed on the dates indicated. See “Unaudited Pro Forma Condensed Combined Financial Information” for more information.

We do not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for us to complete the Business Combination with which a substantial majority of our stockholders do not agree.

Our Current Charter does not provide a specified maximum redemption threshold, except that in no event will we redeem our Public Shares in an amount that would cause our net tangible assets, after payment of the deferred underwriting commissions, to be less than $5,000,001 upon completion of our initial business

100

combination (such that we do not then become subject to the SEC’s “penny stock” rules), or any greater net tangible asset or cash requirement that may be contained in the agreement relating to our initial business combination. As a result, we may be able to complete our initial business combination even though a substantial majority of our public stockholders do not agree with the transaction and have redeemed their shares or have entered into privately negotiated agreements to sell their shares to the Sponsor, our officers and directors, advisors or any of their affiliates. In the event the aggregate cash consideration we would be required to pay for all Class A Common Stock that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed initial business combination exceed the aggregate amount of cash available to us, we will not complete the initial business combination or redeem any shares, all Class A Common Stock submitted for redemption will be returned to the holders thereof, and we instead may search for an alternate business combination.

If the Business Combination’s benefits do not meet the expectations of investors, stockholders or financial analysts, the market price of our Class A Common Stock may decline.

If the benefits of the Business Combination do not meet the expectations of investors or securities analysts, the market price of our Class A Common Stock prior to the Closing may decline. The market value of our Class A Common Stock at the time of the Business Combination may vary significantly from its price on the date the Business Combination Agreement was executed, the date of this proxy statement/prospectus, or the date on which our stockholders vote on the Business Combination.

In addition, following the Business Combination, fluctuations in the price of our Class A Common Stock could contribute to the loss of all or part of your investment. Any of the factors listed below could have a material adverse effect on your investment in our Class A Common Stock and our Class A Common Stock may trade at a price significantly below the price you paid for it. In such circumstances, the trading price of our Class A Common Stock may not recover and may experience a further decline.

Factors affecting the trading price of our Class A Common Stock following the Business Combination may include:

•

actual or anticipated fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

•

changes in the market’s expectations about our operating results;

•

success of competitors;

•

our operating results failing to meet the expectation of securities analysts or investors in a particular period;

•

changes in financial estimates and recommendations by securities analysts concerning New Senti or the market in general;

•

operating and stock price performance of other companies that investors deem comparable to New Senti;

•

changes in laws and regulations affecting our business;

•

commencement of, or involvement in, litigation involving New Senti;

•

changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

•

the volume of shares available for public sale;

•

any major change in our board of directors or management;

•

sales of substantial amounts of securities by our directors, executive officers or significant stockholders or the perception that such sales could occur;

101

•

general economic and political conditions such as recessions, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism; and

•

other developments affecting the biotechnology industry.

Broad market and industry factors may materially harm the market price of our Class A Common Stock irrespective of our operating performance. The stock market in general and Nasdaq have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of our securities, may not be predictable. A loss of investor confidence in the market for retail stocks or the stocks of other companies, notably in the biotechnology industry, which investors perceive to be similar to New Senti could depress our stock price regardless of our business, prospects, financial conditions or results of operations. A decline in the market price for our Class A Common Stock also could adversely affect our ability to issue additional securities and our ability to obtain additional financing in the future.

We are currently an emerging growth company within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are currently an emerging growth company within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, our stockholders may not have access to certain information they may deem important. We could remain an emerging growth company for up to five years from the date of our IPO, although circumstances could cause us to lose that status earlier, including if the market value of our Class A Common Stock held by non-affiliates exceeds $700,000,000 as of any June 30 before that time, in which case we would no longer be an emerging growth company as of the following December 31. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. We have elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accountant standards used.

Our directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to our Public Stockholders.

The Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of

102

intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per public share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the funds held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act. However, we have not asked the Sponsor to reserve for such indemnification obligations, nor have we independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of our company. Therefore, we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

If the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against the Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors, in exercising their business judgment, may choose not to do so if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. We have not asked the Sponsor to reserve for such indemnification obligations and we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. Accordingly, we cannot provide any assurance that due to claims of creditors the actual value of the per-share redemption price will not be less than $10.00 per Public Share.

In connection with the recent restatement of our financial statements, our management has concluded that our disclosure controls and procedures were not effective as of September 30, 2021 due to a material weakness in internal control over financial reporting solely related to our accounting for complex financial instruments. If we are unable to maintain an effective system of disclosure controls and procedures and internal control over financial reporting, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and materially and adversely affect our business and financial results.

Management concluded that it was appropriate to restate our previously issued audited balance sheet as of May 28, 2021, filed as Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on June 4, 2021, our unaudited interim financial statements included in our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2021, filed with the SEC on August 6, 2021, and our unaudited interim financial statements included in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021, filed with the SEC on November 10, 2021 due to an error in presentation of a portion of Class A Common Stock subject to redemption as permanent equity. As part of such process, we identified a material weakness in our internal

control over financial reporting, solely related to our accounting for complex financial instruments.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected and corrected on a timely basis. Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. We expect to take steps to remediate the material weakness, but there is no assurance that any remediation efforts will ultimately have the intended effects.

If we identify any new material weaknesses in the future, any such newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price

103

may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.

The Business Combination is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all.

The completion of the Business Combination is subject to a number of conditions. The completion of the Business Combination is not assured and is subject to risks, including the risk that approval of the Business Combination by DYNS stockholders is not obtained or that there are not sufficient funds in the Trust Account, in each case subject to certain terms specified in the Business Combination Agreement (as described in the section entitled “The Business Combination Agreement – Conditions to Closing”), or that other Closing conditions are not satisfied. If DYNS does not complete the Business Combination, DYNS could be subject to several risks, including:

•

the parties may be liable for damages to one another under the terms and conditions of the Business Combination Agreement;

•

negative reactions from the financial markets, including declines in the price of our Class A Common Stock due to the fact that current prices reflect a market assumption that the Business Combination will be completed;

•

the attention of our management will have been diverted to the Business Combination rather than the pursuit of other opportunities in respect of an initial business combination; and

•

we will have a limited period of time, if any, to complete an alternative initial business combination and we may not be as attractive to potential alternative partners to an initial business combination if we are unable to complete the Business Combination.

The listing of New Senti’s securities on Nasdaq will not benefit from the process undertaken in connection with an underwritten initial public offering.

Upon the Closing, we intend to list the Class A Common Stock (which will be New Senti Common Stock) on Nasdaq under the symbol “SNTI.” Unlike an underwritten initial public offering of New Senti’s securities, the listing of New Senti’s securities as a result of the Business Combination will not benefit from the following:

•

the book-building process undertaken by underwriters, which helps to inform efficient price discovery with respect to opening trades of newly listed securities;

•

underwriter support to help stabilize, maintain or affect the public price of the securities immediately after listing; and

•

underwriter due diligence review of the offering and potential liability for material misstatements or omissions of fact in a prospectus used in connection with the securities being offered, or for statements made by its securities analysts or other personnel.

The lack of such a process in connection with the listing of New Senti’s securities could result in diminished investor demand, inefficiencies in pricing and a more volatile public price for New Senti’s securities during the period immediately following the listing than would typically be experienced in connection with an underwritten initial public offering.

The ability of DYNS stockholders to exercise redemption rights with respect to a large number of shares of Class A Common Stock could increase the probability that the Business Combination would be unsuccessful and that stockholders would have to wait for liquidation in order to redeem their shares of Class A Common Stock.

At the time we entered into the Business Combination Agreement and related transaction documents, we did not know how many stockholders would exercise their redemption rights, and therefore we structured the

104

Business Combination based on our expectations as to the number of shares that will be submitted for redemption. The Business Combination Agreement requires us to have at least $150 million of aggregate cash proceeds available from the Trust Account, after giving effect to redemptions of Public Shares, if any, but before any transaction expenses. If a larger number of shares are submitted for redemption than we initially expected, this may limit our ability to complete the Business Combination or optimize our capital structure.

The consummation of the Business Combination is conditioned on, among other things, there being at least $150,000,000 in cash available at Closing. DYNS has entered into Non-Redemption Agreements with the Anchor Investors to assist with satisfying this condition, however, the Anchor Investors’ commitments not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. Despite the Non-Redemption Agreements, there is no guarantee that there will be $150,000,000 in cash available at Closing. As this condition is for Senti’s benefit, it is possible that Senti could waive it prior to Closing, although there is no guarantee that it would. If Senti did waive the condition in these circumstances, it is possible that New Senti would have insufficient capital to conduct and grow its business after Closing in the manner described in this proxy statement/prospectus.

In connection with the execution of the Business Combination Agreement, the Sponsor, DYNS and each of the Anchor Investors entered into Non-Redemption Agreements. Pursuant to the Non-Redemption Agreements, each of the Anchor Investors agreed for the benefit of DYNS (a) to not redeem the shares of Class A Common Stock beneficially owned by it, or any other shares, capital stock or other equity interests, as applicable, of DYNS and b) to not, among other things, sell encumber or otherwise transfer these shares. As at April 29, 2022, an aggregate of 7,968,483 shares of Class A Common Stock are held subject to Non-Redemption Agreements. However, pursuant to these Non-Redemption Agreements, the Anchor Investors may sell, encumber or otherwise transfer the shares of Class A Common Stock beneficially owned and held by them in connection with programmatic, non-discretionary sales required due to client redemptions (and not, for the avoidance of doubt, due to active portfolio management activity) in mutual funds managed or offered by each of the Anchor Investors. As a result of these sales, the number of shares of non-redeemable Class A Common Stock subject to Non-Redemption Agreements would be reduced, which would cause an increase in the number of shares of redeemable Class A Common Stock. The subsequent holders of these shares of Class A Common Stock from any such sales would have the right to demand that DYNS redeem their shares for a pro rata portion of the cash held in the Trust Account. Despite the Non-Redemption Agreements, DYNS cannot guarantee that there will be at least $150,000,000 in Available Closing Cash (as defined in the Business Combination Agreement), which is a condition DYNS is required to perform in order to consummate the Business Combination. Pursuant to the Business Combination Agreement, Senti may a) extend the time for the performance of any of the obligations or other acts required of DYNS as set forth in the Business Combination Agreement, or b) waive compliance by DYNS with any of the agreements or conditions set forth in the Business Combination Agreement. However, DYNS cannot guarantee that Senti will grant such an extension or waiver.

There is no guarantee that a stockholder’s decision to continue to hold shares of Class A Common Stock following the Business Combination will put the stockholder in a better future economic position than if they decided to redeem their Public Shares for a pro rata portion of the Trust Account, and vice versa.

DYNS can give no assurance as to the price at which a stockholder may be able to sell its Public Shares in the future following the completion of the Business Combination or any alternative business combination. Certain events following the consummation of any initial business combination, including the Business Combination, may cause an increase in DYNS’s share price, and may result in a lower value realized now than a stockholder of DYNS might realize in the future had the stockholder redeemed their shares. Similarly, if a stockholder does not redeem their shares, the stockholder will bear the risk of ownership of the Public Shares after the consummation of any initial business combination, including the Business Combination, and there can be no assurance that a stockholder can sell its shares in the future for a greater amount than the redemption price. A stockholder should consult the stockholder’s own tax and/or financial advisor for assistance on how this may affect his, her or its individual situation.

105

If DYNS stockholders fail to comply with the redemption requirements specified in this proxy statement/ prospectus, they will not be entitled to redeem their Class A Common Stock for a pro rata portion of the funds held in the Trust Account.

In order to exercise their redemption rights, Public Stockholders are required to submit a request in writing and deliver their stock to DYNS’s transfer agent at least two business days prior to the Special Meeting. Stockholders electing to redeem their shares will receive their pro rata portion of the Trust Account less income and franchise taxes payable and less the reimbursement prior to Closing of up to $163,889 in franchise taxes paid by DYNS in 2022 (provided that such reimbursement shall not reduce the Trust Account balance below $230,000,000), calculated as of two business days prior to the anticipated consummation of the Business Combination. See the section entitled “Special Meeting of DYNS Stockholders—Redemption Rights” for additional information on how to exercise your redemption rights.

Stockholders of DYNS who wish to redeem their shares for a pro rata portion of the Trust Account must comply with specific requirements for redemption that may make it more difficult for them to exercise their redemption rights prior to the deadline.

Public Stockholders who wish to redeem their shares for a pro rata portion of the Trust Account must, among other things, as fully described in the section entitled “Special Meeting of DYNS Stockholders— Redemption Rights,” deliver their shares (either physically or electronically) to Continental (or through DTC to Continental) prior to June 3, 2022.

If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 15% of DYNS Common Stock issued in the Initial Public Offering, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of common stock issued in the Initial Public Offering.

A Public Stockholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, with respect to

15% or more of the Public Shares issued in the Initial Public Offering. In order to determine whether a stockholder is acting in concert or as a group with another stockholder, DYNS will require each Public Stockholder seeking to exercise redemption rights to certify to DYNS whether such stockholder is acting in concert or as a group with any other stockholder. Such certifications, together with other public information relating to stock ownership available to DYNS at that time, such as Section 13D, Section 13G and Section 16 filings under the Exchange Act, will be the sole basis on which DYNS makes the above-referenced determination. Your inability to redeem any such excess shares will reduce your influence over DYNS’s ability to consummate the Business Combination and you could suffer a material loss on your investment in DYNS if you sell such excess shares in open market transactions. Additionally, you will not receive redemption distributions with respect to such excess shares if DYNS consummates the Business Combination. As a result, you will continue to hold that number of shares aggregating to more than 15% of the shares sold in the Initial Public Offering and, in order to dispose of such excess shares, would be required to sell your stock in open market transactions, potentially at a loss. DYNS cannot assure you that the value of such excess shares will appreciate over time following the Business Combination or that the market price of Class A Common Stock will exceed the per-share redemption price. Notwithstanding the foregoing, stockholders may challenge DYNS’s determination as to whether a stockholder is acting in concert or as a group with another stockholder in a court of competent jurisdiction.

However, DYNS’s stockholders’ ability to vote all of their shares (including such excess shares) for or against the Business Combination is not restricted by this limitation on redemption.

106

DYNS’s independent registered public accounting firm’s report contains an explanatory paragraph that expresses substantial doubt about DYNS’s ability to continue as a “going concern.”

DYNS’s independent registered public accounting firm’s report, which is set forth in DYNS’s Annual Report on Form 10-K filed with the SEC on March 7, 2022, contains an explanatory paragraph that expresses substantial doubt about DYNS’s ability continue as a “going concern.” As of December 31, 2021, DYNS had $889,323 in cash held outside of the Trust Account and a working capital deficit of $1,984,816. Further, DYNS has incurred and expects to continue to incur significant costs in connection with the Business Combination. For the reasons set forth in the “Risk Factors” section of this proxy statement/prospectus, including the fact that there are conditions to be satisfied prior to the consummation of the Business Combination (and that such conditions may not be satisfied), we cannot assure you that our plans to consummate the Business Combination will be successful. This uncertainty raises substantial doubt about DYNS’s ability to continue as a going concern if the Business Combination is not consummated.

Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Business Combination.

There can be no assurances that additional demands, or complaints asserting similar allegations, will not be made or filed with respect to the proposed Business Combination. If additional similar demands or complaints are made or filed, absent new or different allegations that are material, neither DYNS nor Senti will necessarily publicly announce them.

Changes in laws or regulations related to business combination transactions involving SPACs may materially adversely affect DYNS’s ability to negotiate and complete an initial business combination (including the proposed Business Combination with Senti).

On March 30, 2022, the SEC issued proposed rules relating to, among other items, enhancing disclosures in business combination transactions involving SPACs and private operating companies, amending the financial statement requirements applicable to transactions involving shell companies, enhancing disclosures regarding projections in SEC filings in connection with proposed business combination transactions, increasing the potential liability of certain participants in proposed business combination transactions, and the extent to which SPACs could become subject to regulation under the Investment Company Act of 1940. These rules, if adopted, whether in the form proposed or in a revised form, may materially adversely affect DYNS’s ability to (1) complete the Business Combination with Senti, or (2) if we do not complete the Business Combination with Senti, to engage financial and capital market advisors and negotiate and complete an alternative initial business combination, and, in each case, may increase the costs and time related thereto.

107

SPECIAL MEETING OF DYNS STOCKHOLDERS

General

DYNS is furnishing this proxy statement/prospectus to its stockholders as part of the solicitation of proxies by the Board for use at the Special Meeting to be held on June 7, 2022 and at any adjournment or postponement thereof. This proxy statement/prospectus provides DYNS’s stockholders with information they need to know to be able to vote or direct their vote to be cast at the Special Meeting.

Date, Time and Place

The Special Meeting will be held on June 7, 2022, at 10:00 AM, Eastern Time, via live webcast at the following address: https://www.cstproxy.com/dspc/2022. In light of the COVID-19 pandemic and to support the well-being of DYNS’s stockholders, directors and management, the Special Meeting will be completely virtual.

Voting Power; Record Date

You will be entitled to vote or direct votes to be cast at the Special Meeting if you owned shares of DYNS Common Stock at the close of business on May 3, 2022, which is the Record Date. You are entitled to one vote for each share of DYNS Common Stock that you owned as of the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker, bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 29,465,500 shares of DYNS Common Stock outstanding, of which 23,000,000 are Public Shares, and 6,465,500 shares are held by the Sponsor.

Vote of the Sponsor, Directors and Officers

In connection with the Initial Public Offering, DYNS entered into agreements with each of its Sponsor, directors and officers pursuant to which each agreed to vote the Founder Shares, Private Placement Shares and any Public Shares owned by them in favor of the Business Combination Proposal and for all other proposals presented at the Special Meeting (including the Proposals).

In connection with and as partial consideration for DYNS proceeding with the Initial Public Offering, and for the covenants and commitments of DYNS set forth in the IPO letter agreement (but, for the avoidance of doubt, for no other or additional consideration in connection with the Business Combination), DYNS’s Sponsor, directors and officers have waived any redemption rights with respect to the Founder Shares, Private Placement Shares and any Public Shares which they may hold, and the Sponsor has also agreed to waive its redemption rights with respect to any other equity securities of DYNS it holds.

Quorum and Required Vote for Proposals

A quorum of DYNS stockholders is necessary to hold a valid meeting. A quorum will be present at the Special Meeting if a majority of the voting power of all outstanding shares of DYNS Common Stock entitled to vote at the meeting are represented in person (which would include presence at a virtual meeting) or by proxy. As of May 3, 2022, the Record Date, there were 23,715,500 shares of Class A Common Stock and 5,750,000 shares of Class B Common Stock outstanding; therefore, a total of 14,732,751 shares of DYNS Common Stock must be represented at the Special Meeting in order to constitute a quorum. Abstentions and withheld votes will count as present for the purposes of establishing a quorum, but will not count as votes cast at the Special Meeting for any of the Proposals. Because the Proposals are “non-discretionary” items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker “non-vote” will be deemed to have occurred for each of the Proposals. Broker “non-votes” will not be counted as present for purposes of determining whether a quorum is present. As of the Record Date, the Sponsor holds approximately 21.9% of the outstanding DYNS Common Stock.

108

The Proposals presented at the Special Meeting will require the following votes:

•

The approval of the Charter Amendment Proposal will require the affirmative vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately, as well as the vote of a majority of the issued and outstanding shares of the Class A Common Stock and Class B Common Stock, voting together as a single class. Accordingly, a DYNS stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting or an abstention will have the same effect as a vote “AGAINST” the Charter Amendment Proposal.

•

Abstentions and Broker Non-Votes

At the Special Meeting, DYNS will count a properly executed proxy marked “ABSTAIN” with respect to a particular Proposal as present for purposes of determining whether a quorum is present. Because the Proposals are “non-discretionary” items, your broker will not be able to vote uninstructed shares for any of the Proposals. As a result, if you do not provide voting instructions, a broker “non-vote” will be deemed to have occurred for each of the Proposals. Broker “non-votes” will not be counted as present for purposes of determining whether a quorum is present. The failure to vote, abstentions and broker non-votes will not be counted as votes cast and will have no effect on any of the Proposals presented at the Special Meeting.

Recommendation of the Board

The Board has unanimously determined that each of the Proposals is fair to and in the best interests of DYNS and its stockholders, and has unanimously approved such Proposals. The Board unanimously recommends that stockholders:

•

vote “FOR” the Business Combination Proposal;

•

vote “FOR” the Charter Amendment Proposal;

•

vote “FOR” each of the Advisory Charter Amendment Proposals;

•

vote “FOR” the Nasdaq Stock Issuance Proposal;

•

vote “FOR” the Director Election Proposal;

•

vote “FOR” the Incentive Plan Proposal;

•

vote “FOR” the ESPP Proposal; and

•

vote “FOR” the Adjournment Proposal, if it is presented to the meeting.

109

When you consider the recommendation of the Board in favor of approval of the Proposals, you should keep in mind that the Sponsor, members of the Board and officers of DYNS have interests in the Business Combination that are different from or in addition to (or which may conflict with) your interests as a stockholder. See “Summary of the Proxy Statement/Prospectus—Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination” for additional information on interests of DYNS’s Sponsor, directors and executive officers.

Voting Your Shares

Each share of DYNS Common Stock that you own in your name entitles you to one vote. If you are a record owner of your shares, there are two ways to vote your shares of DYNS Common Stock at the Special Meeting:

•

You Can Vote By Signing and Returning the Enclosed Proxy Card. If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares will be voted as recommended by the Board “FOR” the Business Combination Proposal, the Charter Amendment Proposal, each of the Advisory Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal (if presented). Votes received after a matter has been voted upon at the Special Meeting will not be counted.

•

You Can Attend the Special Meeting and Vote Through the Internet. You will be able to attend the Special Meeting online and vote during the meeting by visiting https://www.cstproxy.com/dspc/2022 and entering the control number included on your proxy card or on the instructions that accompanied your proxy materials, as applicable.

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. If you wish to attend the Special Meeting and vote online and your shares are held in “street name,” you must obtain a legal proxy from your broker, bank or nominee. That is the only way DYNS can be sure that the broker, bank or nominee has not already voted your shares.

Revoking Your Proxy

If you are a record owner of your shares and you give a proxy, you may change or revoke it at any time before it is exercised by doing any one of the following:

•

submit a new proxy card bearing a later date;

•

give written notice of your revocation to DYNS’s Secretary, which notice must be received by DYNS’s Secretary prior to the vote at the Special Meeting; or

•

vote electronically at the Special Meeting by visiting https://www.cstproxy.com/dspc/2022 and entering the control number found on your proxy card, voting instruction form or notice you previously received. Please note that your attendance at the Special Meeting will not alone serve to revoke your proxy.

If your shares are held in “street name” by your broker, bank or another nominee as of the close of business on the Record Date, you must follow the instructions of your broker, bank or other nominee to revoke or change your voting instructions.

Who Can Answer Your Questions About Voting Your Shares

If you are a stockholder and have any questions about how to vote or direct a vote in respect of your DYNS Common Stock, you may contact Continental at (917) 262-2373 or by email at proxy@continentalstock.com.

110

No Additional Matters May Be Presented at the Special Meeting

The Special Meeting has been called only to consider the approval of the Business Combination Proposal, the Charter Amendment Proposal, each of the Advisory Charter Amendment Proposals, the Nasdaq Stock Issuance Proposal, the Director Election Proposal, the Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal. Under DYNS’s bylaws, other than procedural matters incident to the conduct of the Special Meeting, no other matters may be considered at the Special Meeting if they are not included in this proxy statement/prospectus, which serves as the notice of the Special Meeting.

Redemption Rights

Pursuant to the Current Charter, any holders of Public Shares may demand that such shares be redeemed in exchange for a pro rata share of the aggregate amount on deposit in the Trust Account, less any owed but unpaid franchise or income taxes and less the reimbursement prior to Closing of up to $163,889 in franchise taxes paid by DYNS in 2022 (provided that such reimbursement shall not reduce the Trust Account balance below $230,000,000). If demand is properly made and the Business Combination is consummated, these shares will cease to be outstanding and will represent only the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account which holds the proceeds of the Initial Public Offering (including interest earned on the funds held in the Trust Account and not previously released to DYNS to pay its franchise and income taxes). For illustrative purposes, based on funds in the Trust Account of $230,089,497.46 on the Record Date, the estimated per share redemption price would have been approximately $10.00.

In order to exercise your redemption rights, you must:

•

provide, in the written request to redeem your Public Shares for cash to Continental, a “Stockholder Certification” if you are not acting in concert or as a “group” (as defined in Section 13 of the Exchange Act) with any other stockholder with respect to shares of DYNS Common Stock; and

•

Continental Stock Transfer & Trust Company

One State Street Plaza, 30^th Floor

New York, New York 10004

Attn: Mark Zimkind

E-mail: mzimkind@continentalstock.com; or

•

deliver your Public Shares either physically or electronically through DTC to Continental at least two business days before the Special Meeting. Public Stockholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from Continental and time to effect delivery. It is DYNS’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from Continental. However, DYNS does not have any control over this process and it may take longer than two weeks. Stockholders who hold their shares in “street” name will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically. If you do not submit a written request and deliver your Public Shares as described above, your shares will not be redeemed.

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests (and submitting shares to the transfer agent, Continental) and thereafter, with DYNS’s consent, until the Closing. If you delivered your shares for redemption to Continental and decide within the required timeframe not to exercise your redemption rights, you may request that Continental return the shares (physically or electronically). You may make such request by contacting Continental at (917) 262-2373, by email at proxy@continentalstock.com or by writing to the address listed above.

111

Prior to exercising redemption rights, stockholders should verify the market price of Class A Common Stock as they may receive higher proceeds from the sale of their Class A Common Stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. We cannot assure you that you will be able to sell your shares of Class A Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in Class A Common Stock when you wish to sell your shares.

If you exercise your redemption rights, your shares of Class A Common Stock will cease to be outstanding upon consummation of the Business Combination and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the Trust Account. You will no longer own those shares and will have no right to participate in, or have any interest in, the future growth of the Combined Company, if any. You will be entitled to receive cash for these shares only if you properly and timely demand redemption.

Morgan on December 17, 2021).

Dissenter Rights

DYNS stockholders do not have dissenter rights in connection with the Business Combination or the other Proposals.

Potential Purchases of Shares

In connection with the stockholder vote to approve the proposed Business Combination, the Sponsor, directors, officers or advisors or their respective affiliates may privately negotiate transactions to purchase DYNS Common Stock from stockholders who would have otherwise elected to have their shares redeemed in conjunction with a proxy solicitation pursuant to the proxy rules for a per-share pro rata portion of the Trust Account. None of DYNS’s Sponsor, directors, officers or advisors or their respective affiliates will make any such purchases when they are in possession of any material non-public information not disclosed to the seller or during a restricted period under Regulation M under the Exchange Act. Such a purchase would include a contractual acknowledgement that such stockholder, although still the record holder of DYNS Common Stock, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights, and could

112

include a contractual provision that directs such stockholder to vote such shares in a manner directed by the purchaser. In the event that the Sponsor, directors, officers or advisors of DYNS or their affiliates purchase shares in privately negotiated transactions from Public Stockholders who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. Any such privately negotiated purchases may be effected at purchase prices that are below or in excess of the per-share pro rata portion of the Trust Account.

Proxy Solicitation

DYNS is soliciting proxies on behalf of the Board. This solicitation is being made by mail but also may be made by telephone or in person. DYNS and its directors, officers and employees may also solicit proxies in person. DYNS will file with the SEC all scripts and other electronic communications that constitute proxy soliciting materials. DYNS will bear the cost of the solicitation.

DYNS has hired Morrow Sodali to assist in the proxy solicitation process. DYNS has agreed to pay approximately $37,500 for proxy solicitation services, exclusive of related disbursements and travel expenses (in each case, if any).

DYNS will ask banks, brokers and other institutions, nominees and fiduciaries to forward the proxy materials to their principals and to obtain their authority to execute proxies and voting instructions. DYNS will reimburse them for their reasonable expenses.

Background of the Business Combination

DYNS is a blank check company incorporated in the State of Delaware on March 1, 2021. The Company was formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. While DYNS was not limited to pursue an acquisition opportunity in any business, industry or sector, DYNS focused on industries that complement our management team’s backgrounds, and capitalized on the ability of our management team to identify and acquire a business, focusing on the healthcare or healthcare-related industries. The transactions contemplated by the Business Combination Agreement and related agreements, including the Business Combination and PIPE Investment, are results of an extensive search for a potential transaction utilizing the networking, investing, operating and successful transaction experience of DYNS’s management team and Board.

113

The terms of the Business Combination Agreement and the various other agreements contemplated therein and herein are the results of extensive arms-length negotiations among DYNS, Senti and certain of its equity holders and their respective representatives. The following is a brief description of the background of these negotiations and summary of the key meetings and events that led to the signing of the Business Combination Agreement. The following chronology does not purport to catalogue every conversation among the parties to the Business Combination Agreement or their respective representatives.

On May 28, 2021, DYNS consummated its Initial Public Offering of 23,000,000 shares of Class A Common Stock (including 3,000,000 shares of Class A Common Stock that were issued pursuant to the underwriter’s exercise of its over-allotment option in full), at an offering price of $10.00 per share, generating, in the aggregate, gross proceeds of $230,000,000. Substantially concurrently with the consummation of our Initial Public Offering and the sale of the Class A Common Stock, we consummated a private placement of 715,500 shares of Class A Common Stock at a price of $10.00 per share, issued to the Sponsor, generating, in the aggregate, gross proceeds of $7,155,000. A total of $230,000,000 was placed in a U.S.-based trust account established for the benefit of our Public Stockholders.

Prior to the consummation of its Initial Public Offering, neither DYNS, nor anyone on its behalf, contacted any prospective target business or had any substantive discussions, formal or otherwise, with respect to a business combination with DYNS.

As described in the prospectus for its Initial Public Offering, DYNS’s business strategy was to identify and complete an initial business combination with a target that operates within the life sciences subsector and that complements the experience and expertise of our management team, directors and strategic advisors.

DYNS identified certain general, non-exclusive criteria and guidelines that it believed were important in evaluating prospective targets for our initial business combination. DYNS broadly focused on target businesses that it believed (i) have a compelling risk/reward proposition, (ii) have product candidates grounded in breakthrough science with competitive positioning, (iii) have product candidates or technologies with market-leading potential, (iv) have assets that could meet unmet medical needs with respect to multiple medical indications with the ability to diversify risk and successfully navigate an economic downturn and changes in the industry landscape, social sustainability trends and an evolving regulatory environment, (v) have an IPO-ready management team, and (vi) have an experienced investor base comprised of experienced life sciences investors who have also provided, and would likely continue to provide, strategic inputs to the company. DYNS believed that it was important to look for investments that satisfied many, though not necessarily all, of these criteria.

After its Initial Public Offering, DYNS commenced an active search for prospective business combination candidates meeting much of the above criteria. DYNS contacted, and was contacted by, a number of individuals and entities with respect to business combination opportunities. During this search process, DYNS reviewed, and entered into preliminary discussions with respect to, a number of acquisition opportunities other than Senti.

During that process, DYNS’s management:

developed an initial list of over 70 potential business combination candidates (and subsequently several others), which were primarily identified through DYNS’s general industry knowledge and network and introductions from DYNS’s directors, advisors or contacts;

conducted at least one meeting with 25 potential business combination candidates;

conducted additional diligence on a subset of those 25 candidates, and entered into customary confidentiality and non-disclosure agreements with 11 potential business combination candidates; and

engaged in meaningful and detailed discussions, due diligence, and negotiations with four potential business combination candidates and their representatives, one of which was Senti.

During May 2021, as part of the process of developing an initial target list described above, DYNS’s management team held calls with its three independent directors – Jay Flatley, David Epstein, and Deep Nishar – and with Bob Langer (DYNS’s Chief Scientific Advisor) to help create a list of targets. During each of those four

114

calls, the directors and Dr. Langer provided ideas of potential targets they knew about, and provided input on DYNS’s target list. In two of those four meetings, Senti came up as a potentially disruptive company with an interesting technology platform. Independently, members of DYNS’s management team (Mostafa Ronaghi and Rowan Chapman) heard about Senti from calls with people in their network during June and July 2021, including from people in the venture capital industry with cell therapy expertise and people from industry with particular expertise in cell therapy and oncology.

In selecting the 25 potential business combination candidates that DYNS’s management team met with following development of the initial list of potential business combination candidates, DYNS’s management team focused on identifying businesses with a combination of all or certain the following general attributes:

have a large target market with favorable trends;

have a compelling risk/reward proposition;

have deep sector expertise in order to convert innovation into commercial success;

are grounded in breakthrough science (i.e. have competitive positioning);

have potential market leading product candidates that could address an unmet medical need and provide significant benefits to patients;

have multiple assets with the ability to diversify risk and successfully navigate an economic downturn, and changes in the industry landscape, social sustainability trends and evolving regulatory environment;

have an IPO-ready management team; and

have an experienced investor base comprised of companies that have been funded by experienced life sciences investors, including venture capitalists, private equity investors, healthcare companies and other institutional investors who have also provided strategic inputs to the company.

Based on the foregoing criteria and evaluation of the targets, including additional diligence conducted on a subset of the 25 potential business combination candidates, DYNS’s management team determined to sign customary confidentiality and non-disclosure agreements with 11 targets, and then focused deeper evaluation, analysis and due diligence efforts on four potential business combination candidates, one of which was Senti.

DYNS subsequently received, subject to confidentiality obligations requiring DYNS to keep such materials confidential, and DYNS’s management team reviewed business plans, financial statements and market size projections and certain other due diligence information of such four target businesses, one of which was Senti.

DYNS’s management team engaged in varying levels of further due diligence, evaluation and analysis and discussions with these four potential business combination targets. This additional due diligence, evaluation and analysis included access to materials in online data rooms and additional presentations and discussions with these potential business combination targets’ management and included, in addition to the general business and financial due diligence described in this section, as applicable with respect to each potential business combination target:

a review and evaluation of certain financial and operating information of each business combination target;

scientific and technological analyses with assessment of product development, commercial, clinical, regulatory and reimbursement success factors of each business combination target;

review of market factors such as size (total addressable market), growth opportunity, competition, and development trends of each business combination target;

115

commercial review of each business combination target, including, where relevant, interviews with key opinion leaders, customers, competitors and industry experts;

financial evaluation including analysis of historical results and modeling of various scenarios; and

review and evaluation of operations including research and development (“R&D”), manufacturing, sales, and distribution.

In addition to Senti, the other three potential targets included (i) a tools and services company focused on cell and gene therapy (“Company A”), which was a commercial-stage business with a group of high quality venture capital investors, (ii) a novel oncology therapeutics company based on a genomics based discovery platform (“Company B”), which was a pre-commercial, clinical-stage business with two product candidates in clinical trials and one pre-clinical product candidate nearing an investigational new drug application (IND) and (iii) a next generation diagnostics company (“Company C”), which was a commercial-stage business.

While Senti was already on DYNS’s target list, on May 28, 2021, Timothy Lu, the Chief Executive Officer of Senti, reached out to a principal at a venture capital fund that had invested in Senti, and who knew DYNS’s Chief Executive Officer, Mostafa Ronaghi, to arrange to discuss a potential business combination with DYNS. On June 4, 2021, Mostafa Ronaghi and Rowan Chapman participated in an introductory call with Dr. Lu. On June 18, 2021, DYNS and Senti executed a mutual nondisclosure agreement in connection with DYNS’s consideration of a possible business combination involving Senti.

On June 1, 2021, our management team entered into a confidentiality agreement with Company C and was granted access to a virtual data room for due diligence purposes. Our management team reviewed documents in the data room, conducted due diligence meetings (including in respect of financial due diligence) with members of the company’s management, and contacted certain external experts, on a confidential basis, in relation to our preliminary diligence findings. On June 7, 2021, DYNS’s management team determined not to pursue a business combination with Company C due to the lack of competitive positioning of Company C’s products and concerns that the financial projections did not support the valuation proposed by Company C.

In subsequent weeks after entering into a confidentiality agreement on June 18, 2021 with Senti and until late August 2021, DYNS’s management team continued to conduct its evaluation, analysis and due diligence of multiple potential business combination targets across life science tools, diagnostics, synthetic biology and therapeutics. This diligence included entering into confidentiality agreements with the other two potential targets (Company A and Company B) and accessing a virtual data room for due diligence purposes in respect of each company. Our management team reviewed documents in the data room, conducted due diligence meetings (including site visits) with members of each company’s management, and contacted certain external experts, on a confidential basis, in relation to our preliminary diligence. In early July, 2021, Mark Afrasiabi participated in a customer diligence call to review Company A’s products and technology. On July 12, 2021, Mostafa Ronaghi and Rowan Chapman made a site visit to Company A’s manufacturing facility. On July 15, 2021, Mostafa Ronaghi flew to New York to visit with Company B’s management for further discussions and, after that trip, the Dynamics management team held multiple teleconference meetings during July and August 2021 with Company A’s management and Company B’s management, which included technical and business presentations, and also consulted with multiple external experts regarding each company’s technology and lead programs.

On July 10, 2021, DYNS was granted access to the Senti virtual data room. The materials in the data room reviewed by DYNS’s management team included audited and unaudited historical financial statements, scientific data, a detailed corporate presentation, detailed presentations on each of Senti’s three lead product candidates, supplemental slide decks on various aspects of Senti’s business, manufacturing presentations, financial information and analyses related to the anticipated cash requirements of Senti’s business, target product profile (TPP) analyses and intellectual property presentations and patent summaries.

From July 19, 2021 to July 21, 2021, DYNS and Senti held a series of in-depth business, operational, and strategy meetings regarding Senti’s business and operations, including in-depth discussions regarding the

116

technology platform, R&D, manufacturing, commercial opportunity, and each of the three lead products. These meetings were attended by Senti’s management team and DYNS’s management team (Omid Farokhzad (other than certain presentations), Mostafa Ronaghi, Mark Afrasiabi and Rowan Chapman). Following these in-depth discussions, while DYNS’s management conducted its evaluation, analysis and due diligence review of other potential business combination targets, from July 21, 2021 to July 29, 2021, the DYNS management team conducted due diligence, evaluation and analysis of Senti, including numerous calls with key opinion leaders in cell therapy and industry experts, while performing scientific and technological analyses to assess the product development, commercial, clinical, regulatory and reimbursement success factors of Senti.

Members of DYNS’s management team also talked to three of Senti’s Scientific Advisory Board (“SAB”) members (Jim Collins, Michael Varney, and Michael Kalos) on three occasions in late July 2021. All four of DYNS’s management team members participated in a call with Jim Collins, while Mostafa Ronaghi, Mark Afrasiabi and Rowan Chapman also participated in the other two calls with SAB members.

Following additional due diligence on Company A, in early August 2021, DYNS’s management team determined not to pursue a business combination with Company A due to concerns regarding public company readiness, concerns about the financial projections and risk of over-paying, and the decision by Company A to pursue alternative financing transactions in the private market.

During late July and until late August, DYNS’s management team continued to perform additional evaluation and analysis of Company B, including diligence sessions on August 6, 2021 and review of a virtual data room. In late August 2021, following such additional evaluation and analysis, DYNS’s management team determined not to pursue a business combination with Company B due to concerns about the competitive positioning of its products and mutual decisions to pursue alternative transactions, including the DYNS management team’s decision to pursue a business combination with Senti.

DYNS did not submit any draft letter of intent, term sheet or similar preliminary proposal to any of the three other potential business combination targets. In reaching its determination on potential business combination targets, including the three other potential business combination targets with which DYNS engaged in due diligence, evaluation, analysis and discussions as described above, the management of DYNS considered a variety of factors, including:

lack of competitive positioning based upon scientific and technological analyses performed by DYNS;

lack of public company readiness based upon a review and evaluation of operations including financials, R&D, manufacturing, sales, and distribution;

questions about financial projections and commercial uptake;

concerns about valuation and risk of over-paying; and

mutual decisions to pursue potential alternative transactions.

Based on the additional due diligence, evaluation and analysis of Senti, DYNS’s decision to pursue a transaction with Senti was based on an investment thesis that Senti (i) has a compelling risk/reward proposition, (ii) has product candidates grounded in breakthrough science that have competitive positioning, (iii) has product candidates or technologies with market-leading potential, (iv) has assets that could meet unmet medical needs with respect to multiple medical indications with the ability to diversify risk and successfully navigate an economic downturn and changes in the industry landscape, social sustainability trends and an evolving regulatory environment, (v) has an IPO-ready management team, and (vi) has an experienced investor base comprised of experienced life sciences investors who have also provided, and would likely continue to provide, strategic inputs to Senti.

Based on our diligence on evaluation of public comparables and conversations with our advisors, on July 28, 2021, two of our directors, Dr. Farokhzad and Dr. Ronaghi met with Dr. Lu for a dinner meeting where valuation in the range of approximately $300 million to $400 million was discussed, pending further more definitive input from DYNS’s advisors.

117

On August 1 and 2, 2021, at DYNS’s request, representatives of J.P. Morgan met with the management of DYNS to provide preliminary advice relating to DYNS’s preparation and submission of a non-binding letter of intent to acquire Senti. J.P. Morgan was not engaged to act as financial advisor to DYNS prior to or after such meeting. Later, on August 1, 2021, DYNS discussed the preparation and submission of a non-binding letter of intent with representatives of Davis Polk & Wardwell LLP (“Davis Polk”), legal advisors to DYNS.

On August 4, 2021, the board of directors of DYNS held a telephonic meeting in which senior management and representatives of Davis Polk were in attendance to discuss the submission of a non-binding letter of intent to acquire Senti. At DYNS’s request, representatives of J.P. Morgan also attended such meeting to provide preliminary advice relating to such submission. After internal discussion among DYNS’s management team and the board of directors of DYNS, and with the unanimous approval of the board of directors of DYNS, on August 5, 2021, DYNS delivered a first draft to Senti of a non-binding letter of intent, which included the following core terms:

•

an equity value of Senti equal to $300 million, payable solely in the form of shares of DYNS Class A Common Stock;

•

financing consisting of (i) $230,0000,000 of equity capital from DYNS’s trust account and (ii) a PIPE financing of between $100,000,000 and $125,000,000;

•

certain conditions to the consummation of the business combination, including stockholder approval and other customary matters, including the receipt of all applicable stock exchange clearances and, solely in respect of Senti’s obligations to consummate the business combination, a minimum cash condition of up to $200,000,000 (before giving effect to any transaction expenses);

•

approximately $350,000,000 of cash being made available to the combined company for use as working capital and for general corporate purposes, including the payment of transaction expenses (assuming no redemptions by Public Stockholders and a PIPE financing of $120,000,000);

•

a board of directors of the combined company consisting of (i) four directors designated by Senti (one of which would be the chief executive officer of Senti), (ii) two directors designated by the Sponsor and (iii) one director mutually agreed by Senti and DYNS;

•

a 180-day lock-up for shares issued in connection with the business combination to existing Senti stockholders;

•

the lock-up applicable to Founder Shares and Private Placement Shares held by the Sponsor described in the prospectus for our Initial Public Offering would continue to apply;

•

any filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS;

•

a customary post-closing incentive equity plan with an initial number of shares reserved and an “evergreen” provision that are customary for recent initial public offerings of companies in Senti’s industry; and

•

a 45-day period of exclusivity in respect of Senti during which the parties would continue diligence and engage in negotiations to determine agreement on the terms of a definitive agreement (subject to a 30-day extension if the parties mutually determine that satisfactory progress has been made in the negotiation of the definitive agreements).

Following the receipt of the non-binding letter of intent, Senti requested a discussion with DYNS to review and discuss the details of the non-binding letter of intent and to engage in additional negotiations. On August 8, 2021, Senti and DYNS held a call to further discuss and negotiate the non-binding letter of intent.

On August 15, 2021, Senti sent a markup to the non-binding letter of intent to DYNS, providing, among other things that (i) exclusivity would be mutual and extend for an initial period of ten days, with a 35 day

118

extension if the Anchor Investors indicate a satisfactory level of support for the proposed business combination, (ii) that all outstanding equity awards of Senti would be excluded in the allocation of the equity value to the existing Senti stockholders, (iii) proposing an earnout to Senti’s existing stockholders of a number of additional shares equal to 8% of the equity value to vest in three tranches upon the achievement of certain share price milestones, (iv) increasing the minimum cash condition to $250,000,000 (after giving effect to any transaction expenses), (v) that 100% of any filing, registration or similar fees would be borne by DYNS, (vi) that the executive officers of Senti would continue to be the management of the Combined Company with substantially similar roles and responsibilities, (vii) that the combined company board would only include one director designated by the Sponsor and (viii) a post-closing incentive equity plan with an initial number of shares reserved for issuance of between 16% and 21% of the outstanding capital stock of the Combined Company and a customary “evergreen” provision and a post-closing employee stock purchase plan with an initial number of shares reserved for issuance of between 1% and 2% of the outstanding capital stock of the Combined Company and a customary “evergreen” provision. Later that day, DYNS reviewed and discussed the revised non-binding letter of intent received from Senti with representatives of Morgan Stanley, in its capacity as DYNS’s financial advisor, and Davis Polk, in detail. At DYNS’s request, representatives of J.P. Morgan also attended such meeting to provide preliminary advice relating to the revised non-binding letter of intent.

After further internal deliberations between DYNS’s management team and its board of directors – and continued diligence on two of the above-mentioned targets during August 2021 – on August 17, 2021, DYNS delivered an updated non-binding letter of intent to Senti. The updated non-binding letter of intent also proposed (i) a mutual exclusivity period of 30 days, in which some of DYNS’s investors would be brought over the wall to review the opportunity and the proposed PIPE financing, with a 30 day extension if Senti and DYNS mutually agree that the Anchor Investors had indicated a satisfactory level of support for the proposed business combination, (ii) including all outstanding equity awards of Senti in the allocation of the equity value to the existing Senti stockholders, (iii) reducing the size of the earnout to 2,000,000 shares vesting in two equal tranches upon the achievement of certain share price milestones within a period of two and three years, respectively with respect to each tranche, following the closing or earlier upon a change of control in which the share price milestone is achieved, which number of shares and vesting parameters were determined by DYNS with the advice of its financial advisors based on the valuation of Senti, (iv) increasing the number of directors designated by our Sponsor to two directors, (v) reducing the minimum cash condition to $200,000,000 (before giving effect to any transaction expenses), (vi) that filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS and (vii) reducing the amount of the shares initially reserved under the post-closing incentive equity plan to 16% of the outstanding capital stock of the combined company, of which 13.5% out of such 16% reserved for issuance would be granted at consummation of the business combination in the form of stock options.

During August 2021, the DYNS management team continued to conduct extensive due diligence, evaluation and analysis of Senti, including numerous calls with experts in cell therapy, oncology, disease indications for Senti products, and cell therapy manufacturing and production, and DYNS also retained an independent law firm to conduct intellectual property due diligence.

On August 25, 2021, Senti sent a markup to DYNS’s August 17, 2021 draft of the non-binding letter of intent. Senti accepted most of the terms from the August 17, 2021 draft but (i) proposed that the Anchor Investors would enter into non-redemption agreements in connection with the business combination and (ii) increased the amount of the shares initially reserved under the post-closing incentive equity plan to 21% of the outstanding capital stock of the combined company, of which 15% out of such 21% reserved for issuance would be granted at consummation of the business combination in the form of stock options.

On August 26, 2021 representatives of Davis Polk met with the management of DYNS to discuss Senti’s revised non-binding letter of intent, including, among other topics, the proposal that the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management) and T. Rowe would enter into non-redemption agreements in connection with the business combination.

On August 26, 2021, the board of directors of DYNS held a telephonic meeting in which senior management and representatives of Davis Polk were in attendance to discuss the execution of a non-binding

119

letter of intent to acquire Senti. After internal discussion among DYNS’s management team and the board of directors of DYNS, the board of directors of DYNS unanimously approved the execution and delivery of a non-binding letter of intent, which included the following core terms:

•

an equity value of Senti equal to $300,000,000 (before accounting for the benefit of the earnout available to existing Senti stockholders), payable solely in the form of shares of DYNS Class A Common Stock;

•

financing consisting of (i) $230,0000,000 of equity capital from DYNS’s trust account, (ii) a PIPE financing of between $100,000,000 and $125,000,000 and (iii) non-redemption agreements from the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management) and T. Rowe;

•

an earnout to Senti’s existing stockholders of 2,000,000 additional shares to vest in two equal tranches of 1,000,000 shares upon the achievement of certain share price milestones within a period of two and three years, respectively with respect to each tranche, following the closing or earlier upon a change of control in which the share price milestone is achieved, which number of shares and vesting parameters were determined by the parties with the advice of their respective financial advisors;

•

certain conditions to the consummation of the business combination, including stockholder approval and other customary matters, including the receipt of all applicable stock exchange clearances and, solely in respect of Senti’s obligations to consummate the business combination, a minimum cash condition of at least $200,000,000 (before giving effect to any transaction expenses);

•

approximately $350,000,000 of cash being made available to the Combined Company for use as working capital and for general corporate purposes, including the payment of transactions expenses (assuming no redemptions by Public Stockholders and a PIPE financing of $120,000,000);

•

a board of directors of the combined company consisting of (i) four directors designated by Senti (one of which would be the chief executive officer of Senti), (ii) two directors designated by our sponsor and (iii) one director mutually agreed by Senti and DYNS;

•

a 180-day lock-up for shares issued in connection with the business combination to existing Senti stockholders;

•

the lock-up applicable to Founder Shares and Private Placement Shares held by our Sponsor described in the prospectus for our Initial Public Offering would continue to apply;

•

any filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS;

•

a post-closing incentive equity plan with an initial number of shares reserved for issuance of 21% of the outstanding capital stock of the combined company, of which 15% out of such 21% reserved for issuance would be granted at consummation of the business combination in the form of stock options, and a customary “evergreen” provision, and a post-closing employee stock purchase plan with an initial number of shares reserved for issuance of between 1% and 2% of the outstanding capital stock of the combined company and a customary “evergreen” provision; and

•

a mutual exclusivity period of 30 days, with a 30-day extension if Senti and DYNS mutually agreed that the Anchor Investors have indicated a satisfactory level of support for the proposed business combination.

On the evening of August 26, 2021, with the unanimous approval of the board of directors of DYNS and the prior approval of the board of directors of Senti, DYNS and Senti executed the non-binding letter of intent (the “LOI”).

Following entry into the LOI, DYNS conducted confirmatory diligence in the subsequent weeks through September 2021, including calls with experts and third-party consultants, to further assess the technology, manufacturing, commercial opportunity, and the target product profile for each of Senti’s lead programs, and also

120

conducted intellectual property due diligence. Meetings with experts and third-party consultants were attended by Mostafa Ronaghi, Mark Afrasiabi and Rowan Chapman from DYNS’s management team. During September 2021, DYNS also spoke with Spark (Roche) and BlueRock (Bayer) to discuss their collaborations with Senti and why they selected Senti to work with. These meetings were attended by the representatives in charge of the respective collaborations from Spark and BlueRock along with Mostafa Ronaghi, Mark Afrasiabi and Rowan Chapman from DYNS’s management team.

On August 31, 2021, representatives of Goodwin Procter LLP (“Goodwin”) and Cooley LLP, legal advisors to Senti, held an introductory call with Davis Polk to discuss the proposed business combination and certain due diligence matters, including, among other topics, a review of the virtual data room established in connection with the proposed business combination and an introduction to legal due diligence topics related to Senti.

On September 3, 2021, representatives of DYNS, Senti, J.P. Morgan, Morgan Stanley, BofA Securities (the latter three parties being the “co-placement agents” and acting as potential co-placement agents) and their respective legal advisors held an introductory call, led by Dr. Farokhzad, DYNS’s Executive Chairman, and Dr. Ronaghi, DYNS’s Chief Executive Officer, to discuss the proposed PIPE financing timeline, the work streams for the PIPE financing, and investor targets. Over the course of the following weeks, the investor targets for the PIPE financing were mutually selected by DYNS and Senti, following consultation with the co-placement agents. Eight of the investor targets, each of whom was invited to conduct due diligence on Senti, were existing DYNS stockholders, and of those eight, three Anchor Investors (namely, Counterpoint Global (Morgan Stanley Investment Management), T. Rowe Price Group, Inc. and Invus Public Equities, L.P.) ultimately decided to participate in the PIPE Investment. All four Anchor Investors also decided to enter into Non-Redemption Agreements. Other investor targets were selected and contacted during this period, following consultation with the co-placement agents, based on such investors’ perceived interest in investing in a preclinical, next-generation cell and gene therapy platform such as Senti’s. There are material relationships between certain PIPE Investors and:

the Sponsor, namely (a) preexisting arm’s length commercial relationships between certain individuals affiliated with the Sponsor (and/or entities affiliated with them) and certain PIPE Investors (including Anchor Investors), and (b) the fact that certain privately held entities affiliated with certain of DYNS’s officers and directors will participate in the PIPE Investment as PIPE Investors and subscribe for an aggregate of 500,000 shares of Class A Common Stock, and such officers and directors are also affiliated with the Sponsor;

•

Senti, due to the fact that such investors are current Senti stockholders, and some of them currently have the right to appoint directors to Senti’s board; and

•

DYNS, on account of (a) such investors’ existing shareholdings, and (b) the fact that such investors have relationships with certain of DYNS’s officers and directors.

On September 3, 2021, Davis Polk was granted access to the Senti virtual data room and began conducting legal due diligence. The materials in the data room reviewed by Davis Polk included, among other things, documents relating to Senti’s corporate governance and capital structure, employees, material contractual relationships, real property and intellectual property. Between September 7, 2021 and September 8, 2021, representatives of Davis Polk, DYNS, Senti, Goodwin, and certain other participants, participated in financial and legal due diligence calls.

Between September 3, 2021 and September 22, 2021, representatives of J.P. Morgan, Morgan Stanley and BofA Securities, as co-placement agents, and Davis Polk and Goodwin assisted Senti and DYNS, based on materials and information provided by the companies, with the investor presentation for the Anchor Investors of DYNS as potential investors in the PIPE financing. The investor presentation outlined the proposed business combination and included information regarding Senti, which was refined through several rounds of review and comment amongst DYNS’s management team, Senti’s management team and their respective advisors.

121

Representatives of Davis Polk and Goodwin also assisted Senti and DYNS in securing non-redemption commitments in respect of such investors’ holdings of DYNS’s Class A Common Stock.

On September 21, 2021, DYNS executed an engagement letter with J.P. Morgan, Morgan Stanley and BofA Securities, effective as of August 28, 2021, pursuant to which J.P. Morgan, Morgan Stanley and BofA Securities were engaged as co-placement agents to DYNS in connection with the potential PIPE financing. Prior to DYNS’s engagement of BofA Securities as a co-placement agent, both Senti and DYNS were advised of the proposed dual role of BofA Securities as both a co-placement agent and a financial advisor to Senti (BofA Securities having been appointed as financial advisor to Senti in September 2021), and each considered the benefits and risks thereof to Senti and DYNS, respectively. Each of DYNS and Senti then consented to the engagement of BofA Securities as a co-placement agent.

On September 22, 2021, following the completion of the investor presentation, representatives of J.P. Morgan, Morgan Stanley and BofA Securities, as co-placement agents, and DYNS began marketing an investment in the PIPE financing to a limited number of DYNS’s investors and representatives of Davis Polk and Goodwin assisted Senti and DYNS seeking non-redemption commitments in respect of such investors’ holdings of Class A Common Stock.

In late September 2021, DYNS and Senti agreed to extend the initial 30-day period of the LOI to secure PIPE investment commitments and non-redemption agreements, before going more broadly to PIPE marketing beyond the limited group of DYNS’s investors.

By the end of October, after feedback from the Anchor Investors and potential PIPE investors, Senti and DYNS decided that, based on discussions with the Anchor Investors and other potential PIPE investors and adverse changes in market conditions, it was clear that the parties would need to negotiate a valuation of Senti that was more attractive to prospective PIPE investors and the Anchor Investors, from whom non-redemption commitments had been requested. During October and November 2021, representatives of Davis Polk and DYNS held numerous discussions with Anchor Investors of DYNS regarding potential non-redemption commitments on terms that would be mutually satisfactory to such Anchor Investors, and DYNS, including a revised valuation of Senti. Based on the discussions with the Anchor Investors and other potential PIPE investors and a comparable companies analysis considered by DYNS’s management team focusing on certain companies that may be deemed comparable to Senti in certain respects, including publicly traded cell therapy companies with a lead product in pre-clinical or phase I development and which had recently become public companies listed on Nasdaq (for further information regarding the comparable companies analysis, please refer to the heading “The Board’s Reasons for Approval of the Business Combination”, below), DYNS then negotiated the potential revised valuation with Senti on or around October 31, 2021. During this negotiation, Senti reiterated its need for non-redemption agreements from the Anchor Investors in order to agree to a reduction in valuation. In the negotiation of the potential revised valuation with Senti, and in order to secure the non-redemption agreements from the Anchor Investors, the Sponsor agreed to give up approximately 17% of its Founder Shares.

Once DYNS agreed to continue to pursue the non-redemption agreements, Senti discussed the transaction and reduced valuation that had been negotiated with Senti with its board of directors on November 8, 2021. After discussion, Senti’s board of directors indicated its continued support for Senti to pursue the potential business combination.

On November 15, 2021, the DYNS board held a teleconference meeting with Davis Polk in attendance, where DYNS’s management reviewed investor feedback from the first stage of the LOI, and based on initial feedback and adverse market conditions for SPACs and therapeutics/cell therapy public companies, management proposed (i) reducing the size of the PIPE financing from $120 million to $75 million, (i) reducing the valuation from $300 million to $240 million fully-diluted pre-money equity value, and (iii) offering Anchor Investors economic consideration to secure non-redemption agreements in the form of new shares, with commensurate forfeiture of Founder Shares by the Sponsor to prevent dilution and help DYNS secure non-redemption

122

commitments. The DYNS board agreed that it made sense to proceed with those changes. The $240 million proposed valuation corresponded to an approximate 11% increase over Senti’s independently valued series B equity financing, priced in the summer of 2020. Between the summer of 2020 and November 2021, the Senti management team had made significant progress across all dimensions of the business, including talent acquisition, R&D, pipeline advancement, intellectual property, manufacturing, and business development, comprising of establishing collaborations with Spark (Roche) and BlueRock (Bayer). The Board also considered the $240 million proposed valuation (to be revised down from $300 million in the LOI) to be appropriate since, subsequent to the date of the LOI, market valuations for companies comparable to Senti had decreased and the market for business combination transactions with SPACs had weakened (for further information regarding the comparable companies analysis, please refer to the heading “The Board’s Reasons for Approval of the Business Combination,” below). This 20% reduction in Senti’s valuation from the valuation in the LOI was intended to reflect these weaker market conditions, with the aim of helping to attract PIPE capital and reduce the risk of redemptions from the Trust Account.

Between August 2021 and the signing of the Business Combination Agreement in December 2021, dozens of calls were held between Dr. Farokhzad and Dr. Lu—between the DYNS management team and its advisors or between broader Senti management and DYNS management—covering numerous topics including deal terms, valuation, board composition, Senti management incentives and employment agreements, milestones, cash burn, public market dynamics, technical development, scientific advances in the field, alternative approaches to manufacturing, potential business development opportunities, detailed discussion of risks as well as other matters.

In addition, DYNS’s independent director, David Epstein, met with Dr. Lu telephonically on September 20, 2021 and December 21, 2021, during which Dr. Lu gave a detailed corporate presentation and answered Mr. Epstein’s questions. Mr. Epstein is uniquely qualified for Senti’s business matters having served as former CEO of Novartis Pharma, where he was involved in numerous new drug applications, and more recently having served as Executive Chairman of Rubius Therapeutics (Nasdaq: RUBY), a cell therapy platform company. Part of the basis for those calls was to explore Mr. Epstein joining Senti’s board.

On November 18, 2021, after further internal deliberations between DYNS’s management team, its board of directors and its financial advisors regarding the feedback from the Anchor Investors and other potential PIPE investors, DYNS delivered an updated non-binding letter of intent to Senti proposing, among other things, the following modifications to the LOI: (i) reducing the equity value of Senti from $300,000,000 to $240,000,000, (ii) reducing the size of the PIPE financing to $75,000,000, (iii) proposing that each of the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), T. Rowe, ARK Investment Management LLC (“ARK”) and Invus Public Equities, L.P. (“Invus”) would enter into non-redemption agreements in connection with the business combination pursuant to which such Anchor Investors would receive additional Class A Common Stock equal to 11.111% of the number of Class A Common Stock held by such Anchor Investor subject to such non-redemption agreement, (iv) proposing that our Sponsor agree to forfeit a number of shares of Founder Shares in an amount equal to the shares of Class A Common Stock to be issued to the Anchor Investors in connection with the foregoing non-redemption agreements, (v) reducing the minimum cash condition to $150,000,000, and (vi) increasing the amount of shares initially reserved under the post-closing incentive equity plan to 22% of the outstanding capital stock of the combined company.

On November 19, 2021, with the unanimous approval of the board of directors of DYNS and the prior approval of the board of directors of Senti, DYNS and Senti executed an amended and restated non-binding letter of intent (the “A&R LOI”), which included the following core terms:

•

an equity value of Senti equal to $240,000,000 (before accounting for the benefit of the earnout available to existing Senti stockholders), payable solely in the form of shares of DYNS Class A Common Stock;

123

•

financing consisting of (i) $230,0000,000 of equity capital from DYNS’s trust account, (ii) a PIPE financing of $75,000,000 and (iii) non-redemption agreements from each of the funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), T. Rowe, ARK and Invus pursuant to which such Anchor Investors would receive additional Class A Common Stock equal to 11.111% of the number of shares of Class A Common Stock held by such Anchor Investors subject to such non-redemption agreements;

•

forfeiture by the Sponsor of a number of Founder Shares in an amount equal to the shares to be issued to the Anchor Investors in connection with the foregoing non-redemption agreements;

•

certain conditions to the consummation of the business combination, including stockholder approval and other customary matters, including the receipt of all applicable stock exchange clearances and, solely in respect of Senti’s obligations to consummate the business combination, a minimum cash condition of at least $150,000,000 (before giving effect to any transaction expenses);

•

approximately $328,000,000 of cash being made available to the combined company (including Senti’s projected $50 million cash balance as of December 31, 2021) for use as working capital and for general corporate purposes, including the payment of transactions expenses (assuming no redemptions by Public Stockholders and a PIPE financing of $75,000,000);

•

a board of directors of the combined company consisting of (i) four directors designated by Senti (one of which will be the chief executive officer of Senti), (ii) two directors designated by our Sponsor and (iii) one director mutually agreed by Senti and DYNS;

•

a 180-day lock-up for shares issued in connection with the business combination to existing Senti stockholders;

•

the lock-up applicable to Founder Shares and Private Placement Shares held by our sponsor described in the prospectus for our IPO would continue to apply;

•

any filing, registration or similar fees would be borne 50% by Senti and 50% by DYNS;

•

a post-closing incentive equity plan with an initial number of shares reserved for issuance of 22% of the outstanding capital stock of the combined company, of which 15% out of such 21% reserved for issuance would be granted at consummation of the business combination in the form of stock options, and a customary “evergreen” provision, and a post-closing employee stock purchase plan with an initial number of shares reserved for issuance of between 1% and 2% of the outstanding capital stock of the combined company and a customary “evergreen” provision; and

•

a mutual exclusivity period of 30 days following the execution of the A&R LOI.

Other than as described above, there were no further negotiations between DYNS and Senti in respect of the equity valuation for Senti.

By the end of November, a significant book of demand for the PIPE financing and the non-redemption commitments on the terms set forth in the A&R LOI began to form.

Between November 19, 2021 and December 2, 2021, Davis Polk prepared a first draft of the Business Combination Agreement, substantially reflecting the terms agreed to in the A&R LOI, which draft DYNS reviewed and discussed with Davis Polk in detail.

On December 2, 2021, Davis Polk sent Goodwin the first draft of the Business Combination Agreement.

124

On December 9, 2021, Goodwin sent Davis Polk their markup of the first draft of the Business Combination Agreement, which DYNS reviewed and discussed with Davis Polk.

On December 10, 2021, the board of directors of Senti held a telephonic meeting in which senior management were in attendance. Also in attendance were representatives of Goodwin and observers of the board of directors. The draft of the Business Combination Agreement and ancillary documents thereto, the status of the PIPE financing related to the Business Combination and Agreement, and negotiation and timing considerations for these transactions was reviewed and discussed. The board of directors engaged in extensive discussions and deliberations with Senti management and advisors with regard to these transactions.

On December 11, 2021, following further internal discussions between DYNS management and its legal advisors, Davis Polk provided Goodwin a revised draft of the Business Combination Agreement that, among other things, (i) revised certain interim operating covenants in respect of Senti’s operations, (ii) reflected that expenses will be borne 50% by DYNS and 50% by Senti and (iii) increased the ability of DYNS to incur working capital loans which DYNS may incur from $1,000,000 to $2,000,000.

On December 14, 2021, Goodwin sent Davis Polk its markup of the December 11, 2021 draft of the Business Combination Agreement, which DYNS reviewed and discussed with Davis Polk.

Between December 14, 2021 and December 19, 2021, representatives of each of DYNS, Senti, Davis Polk and Goodwin met telephonically and exchanged numerous emails to finalize the remaining open items related to the Business Combination Agreement and the other agreements contemplated therein. Following these discussions, representatives from Davis Polk and Goodwin exchanged revised drafts of the Business Combination Agreement and such other agreements, which reflected the outcome of their discussions. In addition, during this period, DYNS negotiated and entered into (i) an engagement letter with J.P. Morgan, pursuant to which J.P. Morgan was engaged as DYNS’s capital markets advisor to provide certain capital markets advisory services in connection with the proposed business combination and (ii) an engagement letter with Morgan Stanley pursuant to which Morgan Stanley was engaged as DYNS’s financial advisor to provide certain financial advisory services in connection with the proposed business combination.

On December 15, 2021, the board of directors of Senti held a meeting via videoconference in which senior management of Senti and Goodwin were in attendance. During this meeting, the draft of the Business Combination Agreement and ancillary documents thereto, the status of the PIPE financing related to the proposed business combination, and negotiation and timing considerations for these transactions were reviewed and discussed. The board concluded this meeting by indicating their continued support for the transaction.

On December 16, 2021, the board of directors of DYNS held a telephonic meeting in which senior management were in attendance. Also in attendance were representatives of Davis Polk, J.P. Morgan, and Morgan Stanley. Prior to the meeting, a slide deck summarizing the significant transaction documents was distributed to the directors with the transaction documents in substantially final form. Dr. Farokhzad updated DYNS’s board of directors on the final due diligence findings and the terms of the proposed business combination, including the resolution of the final outstanding items. Representatives of Morgan Stanley, as financial advisor to DYNS, reviewed the materials prepared by DYNS’s management and Senti with DYNS’s board of directors, and discussed current market conditions and trading valuations of similar public companies in the biotech industry, to aid the DYNS board of directors in its evaluation of the proposed transaction (though Morgan Stanley was not asked to provide, and did not provide, a financial opinion regarding the proposed transaction).

DYNS’s board of directors discussed the manner in which the management of DYNS initially determined, and then subsequently adjusted, the valuation of the consideration, which was based on market conditions and valuation analysis prepared by DYNS’s management team, and a comparable companies analysis considered by DYNS’s management team focusing on certain companies that may be deemed comparable to Senti in certain

125

respects, including publicly traded cell therapy companies with a lead product in pre-clinical or phase I development and which had recently become public companies listed on Nasdaq (for further information regarding the comparable companies analysis, please refer to the heading “The Board’s Reasons for Approval of the Business Combination”, below). A representative of Davis Polk reviewed with the board of directors the fiduciary duties that applied to their consideration of the proposed business combination. A representative of Davis Polk then discussed with the board of directors the proposed terms of the Business Combination Agreement, the PIPE subscription agreements, the non-redemption agreements, the other transaction documents to be entered into in connection with the proposed business combination and the timeline to closing. The board of directors then engaged in extensive discussions and deliberations with DYNS management and advisors. Among other things, the board of directors asked questions pertaining to legal due diligence, valuation, feedback from the Anchor Investors and proposed PIPE investors, risks, timing and process to closing. Following these discussions and deliberations, DYNS’s three independent directors held an executive session to further discuss the merits of the proposed business combination. Upon rejoining the broader board of directors meeting, the three independent directors engaged in an additional questions and answers session. The board subsequently determined by a unanimous vote that the proposed business combination is in the best interests of DYNS and its stockholders and adopted resolutions (i) approving the proposed business combination, the Business Combination Agreement and the consummation of the transactions contemplated thereby and (ii) recommending that the proposed business transaction be submitted to DYNS’s stockholders for approval.

Between December 10 and December 16, 2021, members of Senti’s management provided updates on the status of the proposed transaction to its board of directors, including a slide deck summarizing the proposed business combination, and discussed and deliberated with its directors, via email and telephonic meetings, the outstanding items and any resolutions on the proposed transaction. Additionally, during this period, it was generally agreed upon between Senti and DYNS that Senti’s stockholders would be subject to a twelve-month lock-up period following the consummation of the proposed business combination, while certain large stockholders of Senti would be subject to an eighteen month lock-up period following the consummation of the proposed business combination. Throughout the period, the board of directors of Senti indicated their continued support for the transactions contemplated by the draft of the Business Combination Agreement, subject to further revisions by the authorized officers of Senti.

On December 17, 2021, Senti distributed the proposed transaction documents in substantially final form to its board of directors together with a board resolution seeking approval of the Business Combination and adoption and approval of the Business Combination Agreement and the related ancillary documents and the transactions contemplated therein.

On December 19, 2021, the board of directors of Senti determined by a written unanimous consent that the proposed business combination is in the best interests of Senti and its stockholders and adopted resolutions (i) approving the proposed business combination, the Business Combination Agreement, the PIPE Investment, and the consummation of the transactions contemplated thereby and (ii) recommending that the transaction be submitted to Senti’s stockholders for approval.

On December 19, 2021, following the approval of the proposed business combination by the board of directors of DYNS and Senti’s board of directors, DYNS, Senti, and certain other parties thereto, executed the Business Combination Agreement. Concurrently with the execution of the Business Combination Agreement, (i) DYNS, the Sponsor and certain other signatories thereto entered into the Sponsor Support Agreement (a copy of which is exhibited to the Business Combination Agreement), (ii) DYNS and the PIPE Investors entered into the subscription agreements in connection with the PIPE Investment, (iii) DYNS, the Sponsor and the funds and

126

accounts managed by Counterpoint Global (Morgan Stanley Investment Management), T. Rowe, ARK and Invus entered into the Non-Redemption Agreements, and (iv) DYNS and certain Senti equity holders entered into voting and support agreements in favor of DYNS and Senti.

On December 20, 2021, DYNS and Senti issued a joint press release regarding the proposed business combination and DYNS filed a Current Report on Form 8-K with the SEC announcing the transactions contemplated by the Business Combination Agreement and filing with the SEC the Business Combination Agreement and certain other transaction documents. The final transaction terms (as detailed in the final investor presentation on file with the SEC) included a $240 million pre-money equity value for Senti, a $66.8 million PIPE financing (i.e. the PIPE Investment), $86.9 million of Non-Redemption Agreements with Anchor Investors, a pro forma equity market capitalization of $601 million and a pro forma enterprise value of $276 million (net of estimated transaction costs), in each case assuming no redemptions from the Trust Account.

Since December 20, 2021, DYNS and Senti, along with their respective advisors, have worked jointly on the preparation of this proxy statement/prospectus.

Throughout January 2022 and early February 2022, DYNS and Senti, along with their respective advisors, were in regular contact regarding the status of the capital markets in the United States and the market for de-SPAC transactions, in particular. In light of those discussions, DYNS and Senti, along with certain members of Senti’s executive team, agreed to restructure certain option grants made at the time the Business Combination Agreement was signed. In particular, certain Senti executives agreed to forfeit certain options granted to them at the time the Business Combination Agreement was signed depending on the level of redemptions of Public Shares at Closing; the options granted to all other employees at signing would, however, continue to be held by those employees after Closing, irrespective of the level of redemptions of Public Shares at Closing. In addition, it was agreed that the vesting period for the options held by executives whose options may be subject to forfeiture (as described above) will commence at Closing, whereas the vesting period for all other employees’ options commenced at the time the Business Combination Agreement was signed. These changes were given effect by Amendment No. 1 to Business Combination Agreement (which is attached to this proxy statement/prospectus as Annex AA), and by Senti and the relevant executives agreeing to amend the option award agreements they had previously entered into at the time the Business Combination Agreement was executed.

On or about February 12, 2022, Timothy Lu and Philip Lee’s Senti Support Agreements (as defined below) were amended with the effect that certain securities held by them would be subject to a three year lock-up period following the Closing, which lock-up period would not, unlike the lock-up periods applicable to other Senti stockholders who had signed Senti Support Agreements, terminate early based on the share price performance of Class A Common Stock (which would be New Senti Common Stock) following the Closing.

On May 9, 2022, DYNS, the Sponsor and the Anchor Investors agreed to amend the Non-Redemption Agreements such that the number of shares of Class A Common Stock to which each Anchor Investor may be entitled equals 11.111% of the number of Public Shares such Anchor Investor holds at the time the Business Combination is consummated (as opposed to when the Non-Redemption Agreement was signed). As 7,968,483 Public Shares in the aggregate were subject to Non-Redemption Agreements as at April 29, 2022, it is anticipated that the Sponsor will forfeit 885,377 Founder Shares at Closing, or approximately 15.4% of its Founder Shares.

DYNS and Senti have continued and expect to continue regular discussions regarding the execution and timing of the Business Combination and to take actions and exercise their respective rights under the Business Combination Agreement to facilitate the completion of the Business Combination.

Certain Engagements in Connection with the Business Combination and Related Transactions

Morgan Stanley was engaged by DYNS to act as financial advisor to DYNS in connection with the Business Combination, and will receive a customary advisory fee in connection therewith. DYNS also engaged Morgan

127

Stanley to act as co-placement agent with J.P. Morgan and BofA Securities on the $66.8 million PIPE Investment, pursuant to which the co-placement agents will receive customary fees. In connection with its roles as financial advisor to DYNS and co-placement agent to DYNS on its PIPE Investment, Morgan Stanley will receive total fees of $1,889,776. In addition, DYNS engaged J.P. Morgan as capital markets advisor in connection with the Business Combination. J.P. Morgan also acted as the sole underwriter on the Initial Public Offering and will receive a deferred underwriting fee of $7,050,000 (this amount having being reduced from $8,050,000 by $1,000,000 by agreement with J.P. Morgan on December 17, 2021) upon consummation of the Business Combination. The deferred underwriting fee, if paid, would be in addition to the $4,600,000 of underwriting fees paid to J.P. Morgan at the time the Initial Public Offering was completed. The deferred underwriting fee of $7,050,000 payable to J.P. Morgan if the Business Combination is consummated may create a conflict of interest for J.P. Morgan in its capacity as capital markets advisor in connection with the Business Combination. J.P. Morgan was not engaged to act as financial advisor to DYNS in connection with the Business Combination.

J.P. Morgan, Morgan Stanley and BofA Securities (together with their affiliates) are full service financial institution engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, wealth management, investment research, principal investing, lending, financing, hedging, market making, brokerage and other financial and non-financial activities and services. In addition, J.P. Morgan, Morgan Stanley and BofA Securities (together with their affiliates) may provide investment banking and other commercial dealings to DYNS, Senti and their respective affiliates in the future, for which they would expect to receive customary compensation. In addition, in the ordinary course of their business activities, J.P. Morgan, Morgan Stanley and BofA Securities and their affiliates, officers, directors and employees may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of DYNS, Senti or their respective affiliates. J.P. Morgan, Morgan Stanley and BofA Securities and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The Board’s Reasons for Approval of the Business Combination

DYNS was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. DYNS sought to do this by utilizing the networks and industry experience of both its management team and the Board to identify, acquire and operate one or more businesses within or outside of the United States.

The Board met via videoconference on December 16, 2021 to, among other things, discuss a potential business combination with Senti, and on December 16, 2021, unanimously approved the Business Combination and the Business Combination Agreement. Prior to reaching the decision to approve the Business Combination and the Business Combination Agreement, the Board consulted with our management, as well as with our legal and financial advisors.

In addition, the Board reviewed various industry and scientific data, including, but not limited to, Senti’s existing business model and Senti’s product candidates and development pipeline, and reviewed the results of management’s due diligence review of Senti, which took place over a period of more than five months beginning in July 2021 and continuing through the signing of the Business Combination Agreement on December 19, 2021, including extensive meetings and calls with Senti’s management team, review of Senti’s material contracts, intellectual property matters, labor matters, operations, financing and accounting due diligence, tax due diligence, engaging and consulting financial advisors, and other legal due diligence with assistance from our legal counsel and special intellectual property counsel before determining that the Business Combination was in the best interests of DYNS and its stockholders. The Board also determined,

128

after a thorough review of other business combination opportunities reasonably available, that the Business Combination represents the best potential business combination based upon the process utilized to evaluate and assess other potential acquisition targets.

Our Board also reviewed a comparable companies analysis considered by DYNS’s management team which focused on certain companies that may be deemed similar to Senti in certain respects, including publicly traded cell therapy companies with a lead product in pre-clinical or phase I development, and which had recently become public companies listed on Nasdaq. The comparable companies analysis provided for the companies, which may be deemed to be comparable to Senti, and financial metrics set forth in the table below.


Company	Market Capitalization (bn)		Firm Value (bn)		Cash as a Percentage of Market Capitalization⁽¹⁾	Net Cash as a Percentage of Next 12 Months Operating Expenditure⁽¹⁾⁽²⁾	Lead Asset Indication(s)	Phase

(1)

Following execution of the Business Combination Agreement, DYNS management determined that due to a scrivener’s error, the figures for Sana and Lyell for these two financial metrics were incorrectly presented in the analysis as being the other company’s figures. This did not affect the mean and median values shown in the analysis. DYNS management subsequently brought this discrepancy to the DYNS Board’s attention for informational purposes. The table above reflects the correct position as if the scrivener’s error had not been made.

(2)	Operating expenditure inclusive of selling, general and administrative expenses and research and development expenses based on time-weighted, next 12 month analysts’ consensus.

Based on this comparable companies analysis and the findings of other due diligence, including financial due diligence, conducted by our management, our Board determined that Senti presented an investment case that is in line with (or at a material discount to) companies that may be deemed similar to Senti in certain respects including, among other things, because (a) if the Business Combination and PIPE Investment are consummated, Senti is expected to have cash on balance sheet, as compared to its anticipated operating expenditures, which is within the range of cash held by the comparable companies, and (b) the implied firm value of Senti following the consummation of the Business Combination and PIPE Investment (representing a pro forma equity market capitalization of $601 million, assuming no redemptions, and a pro forma enterprise value of $276 million) is in line with other similar publicly traded cell therapy companies with a lead product in phase I development, and at a material discount to the pre-clinical subset of companies.

129

The Board considered a wide variety of factors in connection with its evaluation of the Business Combination. In light of the complexity of those factors, the Board as a whole did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the Board may have given different weight to different factors. This explanation of DYNS’s reasons for the Board’s approval of the Business Combination, and all other information presented in this section, is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section entitled “Forward-Looking Statements.”

In particular, the Board considered the following positive factors, although not weighted or in any order of significance:

•

Pioneering innovation in the field of gene circuit technology. The Board believes that Senti has proven and experienced leadership, which is poised to execute on Senti’s unique approach to developing and manufacturing intelligent gene circuits for use in next-generation cell and gene therapies.

•

Anticipated FDA filings. The Board considered Senti’s anticipated investigational new drug (IND) filings in 2023 for product candidates SENTI-202 and SENTI-301, each of which is discussed in further detail in the section entitled “Information About Senti.”

•

Collaborations with Spark and BlueRock. The Board considered Senti’s existing collaborations with Spark (Roche) and BlueRock (Bayer), which are more fully described in the section entitled “Information about Senti – Material License and Collaboration Agreements,” as providing additional validation of Senti’s clinical strategies.

•

Potential to address an area of high unmet medical need. The Board considered the potential for Senti’s product candidates, should they proceed through clinical trials and be approved for use, to address patients with high unmet needs in oncology, immunology, genetic diseases, neurology, cardiology and ophthalmology, among others.

•

Diversified risk profile from multimodality approach. The Board considered that Senti’s pipeline and platform has several potential therapeutic applications, including in the fields of oncology, gene therapies for tissue-directed targets and cell therapies for regenerative medicine applications. The Board believes that this multimodality approach will help Senti to diversity its business risk.

•

Development of the commercial potential of product candidates, if approved. The Board believes that, driven by its understanding of existing treatment paradigms and patient, physician and payor needs, Senti is in a strong position to build a focused and efficient medical affairs and commercial organization and to commercialize its product candidates, if approved (including by the FDA), in the United States and international markets.

•

Experienced and dedicated management team. The Board believes that Senti has a proven and experienced management team that will effectively lead the Combined Company after the Business Combination. Additionally, the Board considered Senti’s management’s willingness to forfeit certain options with respect to redemptions and recognized the dedication of Senti’s management to attempt to execute on its business plans.

•

Backed by top-tier healthcare investors. Senti’s existing investors include NEA, 8VC, Leaps by Bayer, Amgen Ventures and Lux, Lifeforce Capital, among others, which the Board believes provides additional validation of Senti’s clinical and business strategies. The Board also considered the strong interest in the PIPE Investment in connection with the transaction from seasoned healthcare investors, including T. Rowe, funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), Invus, NEA, 8VC, Lifeforce and others.

•

Financial analysis conducted by DYNS. The financial analysis conducted by DYNS’s management team and reviewed by the Board supported the equity valuation of Senti. This financial analysis included (a) reviewing a comparable companies analysis which considered, among other things,

130

enterprise values and equity values for a variety of cell therapy and gene therapy platforms, including preclinical platforms perceived as next-generation cell therapy or gene therapy platforms, which is what DYNS’s management team believes Senti’s platform may be able to provide, (b) a step-up analysis considering the percentage change in Senti’s proposed equity valuation from its last independently priced equity financing round (its series B convertible preferred stock financing round), which was priced in the summer of 2020, in which DYNS’s management team considered the significant progress Senti had made since then, including corporate partnerships with Roche (Spark) and Bluerock (Bayer), (c) an analysis of the post-initial public offering share price performance of biotechnology companies that had recently offered their securities to the public, (d) a step-up analysis considering median valuation step-up from other biotechnology companies’ last pre-initial public offering equity financing round to their initial public offering in the years 2019, 2020 and 2021, (e) an analysis of the percentage of initial public offerings for biotechnology companies that were in the preclinical phase (like Senti) as opposed to being in various clinical stages of product candidate development, (f) share price performance for de-SPAC mergers closed in the years 2019, 2020 and 2021, along with redemptions data for 20 recently closed de-SPAC mergers, and (g) an analysis of prior initial public offerings of companies involved in cell therapy, gene therapy and gene editing, considering pre-money valuations, step-ups in valuation at the time of the initial public offering from the prior equity financing round and whether the company was in the pre-clinical or clinical phase, among other things.

The Board also identified and considered the following factors and risks weighing negatively against pursuing the Business Combination, although not weighted or in any order of significance:

•

Technical and Clinical Risk. Senti is a preclinical stage biotechnology company, and the Board considered that there is no assurance that Senti will engage in clinical trials or that any clinical trials will succeed.

•

FDA Approval. The Board considered risks associated with the failure to receive FDA approval (in a timely manner or at all) for Senti’s product candidates, should they ultimately reach late-stage clinical development, and the adverse impact that would have on the commercialization of its product candidates.

•

Manufacturing. While Senti has plans to develop a manufacturing facility for its product candidates, the Board considered the risks associated with optimizing and scaling up production for clinical trials and commercial sales.

•

Commercialization. The Board considered the risks that, should Senti’s product candidates proceed through clinical trials and receive FDA approval, they will nevertheless be unable to commercialize them and they will be subject to competition from other businesses involved in developing and commercializing “gene circuit” technology for programing next-generation cell and gene therapies.

•

Reimbursement. The Board considered the risks that, should Senti’s product candidates proceed through clinical trials and receive FDA approval, they do not become eligible for third-party coverage and/or approved for reimbursement.

•

Exclusivity. The Board considered the fact that the Business Combination Agreement includes an exclusivity provision that prohibits DYNS from soliciting other business combination proposals, which restricts DYNS’s ability, so long as the Business Combination Agreement is in effect, to consider other potential business combinations.

•

Other risks. Various other risks associated with the Business Combination and redemptions, the business of DYNS and the business of Senti described in the section entitled “Risk Factors,” including Senti’s ongoing need to raise additional capital to finance its operations.

Based on its review of the forgoing considerations, the Board concluded that the potentially negative factors associated with the Business Combination were outweighed by the potential benefits that it expects DYNS

131

stockholders will receive as a result of the Business Combination. The Board noted that there can be no assurance about future results, including results considered or expected as disclosed in the foregoing reasons.

The preceding discussion of the information and factors considered by the Board is not intended to be exhaustive but includes the material factors considered by the Board. In view of the complexity and wide variety of factors considered by the Board in connection with its evaluation of the Business Combination, the Board did not consider it practical to, nor did it attempt to, quantify, rank or otherwise assign relative weights to the different factors that it considered in reaching its decision. In addition, in considering the factors described above, individual members of the Board may have given different weight to different factors. The Board considered this information as a whole and overall considered the information and factors to be favorable to, and in support of, its determinations and recommendations.

This explanation of the Board’s reasons for its approval of the Business Combination, and all other information presented in this section, is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section entitled “Forward-Looking Statements.”

Summary of Business Combination Agreement

This subsection of the proxy statement/prospectus describes the material provisions of the Business Combination Agreement, but does not purport to describe all of the terms of the Business Combination Agreement. The following summary is qualified in its entirety by reference to the complete text of the Business Combination Agreement, a copy of which is attached as Annex A to this proxy statement/prospectus. You are urged to read the Business Combination Agreement in its entirety because it is the primary legal document that governs the Business Combination.

The Business Combination Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of the Business Combination Agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating the Business Combination Agreement. The representations, warranties and covenants in the Business Combination Agreement are also modified in part by the underlying disclosure schedules delivered by each of DYNS and Senti to each other (the “disclosure schedules”), which are not filed publicly and which are subject to a contractual standard of materiality different from that generally applicable to stockholders, and were used for the purpose of allocating risk among the parties rather than establishing matters as facts. We do not believe that the disclosure schedules contain information that is material to an investment decision. Additionally, the representations and warranties of the parties to the Business Combination Agreement may or may not have been accurate as of any specific date and do not purport to be accurate as of the date of this proxy statement/prospectus. Accordingly, no person should rely on the representations and warranties in the Business Combination Agreement or the summaries thereof in this proxy statement/prospectus as characterizations of the actual state of facts about DYNS, Merger Sub, the Sponsor, Senti or any other matter.

Structure of the Business Combination

On December 19, 2021, DYNS, Merger Sub and Senti entered into the Business Combination Agreement, which provides, among other things, that, on the Closing Date, the parties to the Business Combination Agreement will cause a certificate of merger to be executed and filed with the Secretary of State of the State of Delaware, pursuant to which Merger Sub will merge with and into Senti, with Senti as the surviving company in the merger and, after giving effect to such merger, Senti shall be a wholly owned subsidiary of DYNS.

Pursuant to the Business Combination Agreement, at the Effective Time:

•

each outstanding share of Senti common stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to the Exchange Ratio (rounded down to the nearest whole share);

132

•

each outstanding share of Senti preferred stock will be cancelled and converted into the right to receive a number of shares of Class A Common Stock equal to (i) the aggregate number of shares of Senti common stock that would be issued upon conversion of the shares of Senti preferred stock based on the applicable conversion ratio immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio (rounded down to the nearest whole share); and

•

each outstanding option (whether vested or unvested) to purchase Senti stock will be converted into an option to purchase a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Senti common stock subject to such option as at the time immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, at an exercise price per share equal to the current exercise price per share for such option divided by the Exchange Ratio (rounded up to the nearest whole cent).

The consideration described in the foregoing bullets is collectively referred to as the “Business Combination Consideration.”

In addition, holders of shares of Senti common stock and Senti preferred stock will be eligible to receive (i) 1,000,000 shares of Class A Common Stock, in the aggregate, if, within two calendar years after Closing, the volume weighted average price of Class A Common Stock on Nasdaq, or any other national securities exchange on which the shares of Class A Common Stock are then traded (“VWAP”) is greater than or equal to $15.00 over any 20 trading days within any consecutive 30 trading day period, and (ii) an additional 1,000,000 shares of Class A Common Stock, in the aggregate, if, within three calendar years after Closing, the VWAP is greater than or equal to $20.00 over any 20 trading days within any consecutive 30 trading day period. These 2,000,000 shares of Class A Common Stock (which would be shares of New Senti Common Stock) are referred to as the “Contingency Consideration.” Subject to certain exceptions, and provided the per share value of the consideration to be received by holders of Class A Common Stock in connection with the change of control exceeds one or both of the Contingency Consideration price targets set forth above, if a change of control of New Senti occurs within two or three calendar years (as applicable) following the Closing, then any Contingency Consideration that remains unissued as of immediately prior to the consummation of such change of control will immediately become payable and the former holders of shares of Senti preferred stock and Senti common stock will be entitled to receive the unissued Contingent Consideration prior to the consummation of such change of control.

In connection with the Business Combination, certain related agreements have been, or will be entered into on or prior to the closing of the Business Combination, including the Subscription Agreements (as defined below), the Non-Redemption Agreements, the Investor Rights Agreement, the Sponsor Support Agreement and the Senti Support Agreeements (including amendments thereto). See “— Related Agreements” for more information.

Material Adverse Effect

Under the Business Combination Agreement, certain representations and warranties of Senti and the DYNS Parties are qualified in whole or in part by materiality thresholds. In addition, certain representations and warranties of Senti and the DYNS Parties are qualified in whole or in part by certain “material adverse effect” standards for purposes of determining whether a breach of such representations and warranties has occurred (and for purposes of determining whether certain conditions to Closing have been satisfied, as discussed above in “— Conditions to Closing of the Business Combination”).

Pursuant to the Business Combination Agreement, a “Company Material Adverse Effect” means any state of facts, event, change, effect, occurrence, circumstance or development that, individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (a) the business, assets, results of operations or condition (financial, regulatory, clinical or otherwise) of Senti and its subsidiaries, taken as a whole, or (b) the ability of Senti to consummate the Business Combination; except that, in the case of clause (a), none of the following will be taken into account in determining whether a Company Material Adverse Effect has occurred or would be reasonably expected to occur: any adverse state of facts, event, change, effect, occurrence, circumstance or development arising from or related to (i) general business or economic conditions in or affecting the United States, or changes therein, or the global economy generally, (ii) any national or international political or social conditions in the United States or any other country, including the engagement by the United States or any other country in hostilities, whether or not pursuant to the declaration of a national emergency or war, or the occurrence in any place of any military or terrorist attack, sabotage or cyberterrorism, (iii) changes in conditions of the financial, banking, capital or securities markets generally in the United States or any other country or region in the world, or changes therein, including changes in interest rates in the United States or any other country and changes in exchange rates for the currencies of any countries, (iv) changes or proposed changes in any applicable laws or GAAP after the date of the Business Combination Agreement, (v) any state of facts, event, change, effect, occurrence, circumstance or development that is generally applicable to the industries or markets in which Senti and its subsidiaries operate, (vi) subject to certain exceptions, the execution or public announcement of the Business Combination Agreement or the pendency or consummation of the transactions contemplated by the Business Combination Agreement, including the impact thereof on the relationships, contractual or otherwise, of Senti and its subsidiaries with employees, contingent workers, customers, investors, contractors, lenders, suppliers, vendors, partners, licensors, licensees, or other third parties related thereto, (vii) any failure by Senti and its subsidiaries, taken as a whole, to meet, or changes to, any internal or published budgets, projections, forecasts, estimates or predictions (although the underlying facts and circumstances resulting in such failure may be taken into account), or (viii) any hurricane, tornado, flood, earthquake, tsunami, natural disaster, mudslides, wild fires, epidemics or pandemics or the worsening of any pandemics (including COVID-19), acts of God or other natural disasters or comparable events in the United States or any other country or region in the world, or any escalation of the foregoing. Any state of facts, event, change, effect, occurrence, circumstance or development resulting from a matter described in any of the foregoing clauses (i) through (v) or (viii) may be taken into account in determining whether a Company Material Adverse Effect has occurred or would be reasonably expected to occur solely to the extent the same has a disproportionate adverse effect on Senti and it subsidiaries, taken as a whole, relative to other participants operating in the industries or markets in which Senti and its subsidiaries operate.

Pursuant to the Business Combination Agreement, a “DYNS Material Adverse Effect” means any state of facts, event, change, effect, occurrence, circumstance or development that, individually or in the aggregate, has had

138

or would reasonably be expected to have a material adverse effect on (a) the business, assets, results of operations or condition (financial, regulatory or otherwise) of the DYNS Parties, taken as a whole, or (b) the ability of DYNS or Merger Sub to consummate the Business Combination; provided however, in the case of clause (a), none of the following will be taken into account in determining whether a DYNS Material Adverse Effect has occurred or would be reasonably expected to occur: any adverse state of facts, event, change, effect, occurrence, circumstance or development arising from or related to (i) general business or economic conditions in or affecting the United States, or changes therein, or the global economy generally, (ii) any national or international political or social conditions in the United States or any other country, including the engagement by the United States or any other country in hostilities, whether or not pursuant to the declaration of a national emergency or war, or the occurrence in any place of any military or terrorist attack, sabotage or cyberterrorism, (iii) changes in conditions of the financial, banking, capital or securities markets generally in the United States or any other country or region in the world, or changes therein, including changes in interest rates in the United States or any other country and changes in exchange rates for the currencies of any countries, (iv) changes or proposed changes in any applicable laws or GAAP after the date of the Business Combination Agreement, (v) any state of facts, event, change, effect, occurrence, circumstance or development that is generally applicable to the industries or markets in which any DYNS Party operates, (vi) subject to certain exceptions, the execution or public announcement of the Business Combination Agreement or the pendency or consummation of the transactions contemplated by the Business Combination Agreement, including the impact thereof on the relationships, contractual or otherwise, of any DYNS Party with investors, contractors, lenders, suppliers, vendors, partners, licensors, licensees or other third parties related thereto, (vii) any failure by any DYNS Party to meet, or changes to, any internal or published budgets, projections, forecasts, estimates or predictions (although the underlying facts and circumstances resulting in such failure may be taken into account), or (viii) any hurricane, tornado, flood, earthquake, tsunami, natural disaster, mudslides, wild fires, epidemics or pandemics or the worsening of any pandemic (including COVID-19), acts of God or other natural disasters or comparable events in the United States or any other country or region in the world, or any escalation of the foregoing, (ix) any state of facts, event, change, effect, occurrence, circumstance or development relating to Senti or its subsidiaries or stockholders, (x) any DYNS Stockholder Redemption (as defined in the Business Combination Agreement), in and of itself, or (xi) any breach of any covenants, agreements or obligations of a PIPE Investor under a Subscription Agreement (including any breach of a PIPE Investor’s obligations to fund its commitment thereunder when required); provided, however, that any state of facts, event, change, effect, occurrence, circumstance or development resulting from a matter described in any of the foregoing clauses (i) through (v) or (viii) may be taken into account in determining whether a DYNS Material Adverse Effect has occurred or would be reasonably likely to occur to the extent, and solely to the extent, the same has a disproportionate adverse effect on the DYNS Parties, taken as a whole, relative to other SPACs operating in the industries in which the DYNS Parties operate.

The foregoing description of the Investor Rights Agreement does not purport to be complete and is qualified in its entirety by the terms and conditions of the Investor Rights Agreement, a form of which is exhibited to the Business Combination Agreement, and the terms of which are incorporated herein by reference.

Non-Redemption Agreements

In connection with the execution of the Business Combination Agreement, the Sponsor, as the holder of 5,750,000 Founder Shares, DYNS and each of the Anchor Investors entered into Non-Redemption Agreements.

Pursuant to the Non-Redemption Agreements, each Anchor Investor agreed for the benefit of DYNS (a) to not redeem the shares of Class A Common Stock beneficially owned by it, or any other shares, capital stock or other equity interests, as applicable, of DYNS, and (b) to not, among other things, sell, encumber or otherwise transfer such shares of Class A Common Stock or other equity interests, other than in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. As at April 29, 2022, these Non-Redemption Agreements apply in respect of 7,968,483 shares of Class A Common Stock in the aggregate. In connection with these commitments from the Anchor Investors, the Sponsor has agreed to forfeit 885,377 Founder Shares and DYNS has agreed to cancel such Founder Shares and concurrently issue to the Anchor Investors an equivalent number of shares of Class A Common Stock (in the aggregate), in each case, at or promptly following the Closing, thereby potentially increasing the Anchor Investors’ aggregate ownership interest in New Senti. The potential issuance of such shares of Class A Common Stock to the Anchor Investors is the only consideration which they will potentially receive in connection with their agreement not to redeem their Public Shares. The Sponsor has advised the Board that it believes it is in the best interests of DYNS for the Sponsor to forfeit Founder Shares pursuant to the Non-Redemption Agreements.

150

Neither the Sponsor, DYNS nor the Anchor Investors, either by the terms of the Non-Redemption Agreements or at any time in the future, are to be considered a “group” within the meaning of the Securities Exchange Act of 1934, as amended.

The foregoing description of the Non-Redemption Agreements is subject to and qualified in its entirety by reference to the full text of the form of Non-Redemption Agreement, a copy of which is filed as Exhibit 10.2 to DYNS’s Current Report on Form 8-K filed with the SEC on December 20, 2021, and the terms of which are incorporated herein by reference.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

This section describes the material U.S. federal income tax considerations relevant to (i) U.S. Holders (defined below) of Senti common stock and Senti preferred stock (collectively, “Senti Capital Stock”) who exchange their Senti Capital Stock for shares of Class A Common Stock in the Business Combination, and (ii) holders of Class A Common Stock who elect to have their Class A Common Stock redeemed for cash upon the Closing of the Business Combination. This discussion applies only to holders with respect to shares of Senti Capital Stock and shares of Class A Common Stock, as the case may be, that hold such shares as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment).

This discussion is based on the Code, Treasury Regulations promulgated thereunder (whether final, temporary or proposed), judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect the tax consequences discussed below. No rulings have been or will be sought from the IRS concerning the tax consequences of the Business Combination, the redemption or any other related matter. Accordingly, there can be no assurance that the IRS will not take a contrary position to that discussed below regarding the tax consequences of the Business Combination or the redemption, or, if challenged, that any such contrary position would not be sustained by the courts.

The following discussion does not address the effects of other U.S. federal tax laws, such as estate and gift tax laws, net investment income tax nor does it address any tax consequences arising under applicable state, local or non-U.S. tax laws are not discussed.

This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the Medicare contribution tax on certain net investment income. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

•

banks, insurance companies, and certain other financial institutions;

•

regulated investment companies and real estate investment trusts;

•

brokers, dealers or traders in securities, commodities or currencies;

•

traders in securities that elect to mark to market;

•

tax-exempt organizations or governmental organizations;

•

persons subject to the alternative minimum tax;

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to Class A Common Stock, as the case may be, being taken into account in an applicable financial statement;

•

holders holding Senti Capital Stock or Class A Common Stock as a position in a “straddle,” as part of a “synthetic security” or “hedge,” as part of a “conversion transaction,” or other integrated investment or risk reduction transaction;

•

controlled foreign corporations, passive foreign investment companies, or foreign corporations with respect to which there are one or more United States stockholders within the meaning of Treasury Regulation Section 1.367(b)-3(b)(1)(ii);

•

persons that actually or constructively own 5% or more by vote or value of the outstanding shares of Senti or DYNS;

152

•

S corporations, partnerships or other entities or arrangements treated as partnerships or other flow-through entities for U.S. federal income tax purposes (and investors therein);

•

U.S. Holders having a “functional currency” other than the U.S. dollar;

•

persons who hold or received Senti Capital Stock or Class A Common Stock, as the case may be, pursuant to the exercise of any employee stock option, tax-qualified retirement plan or otherwise as compensation; and

•

“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds.

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of shares of Senti Capital Stock or Class A Common Stock, as the case may be, that is for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity that is classified as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of (1) the United States or (2) any state thereof or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a U.S. court and all substantial decisions of which are subject to the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Senti Capital Stock or Class A Common Stock, the tax treatment of an owner of such entity will depend on the status of the owners, the activities of the entity and certain determinations made at the owner level. Accordingly, entities and arrangements treated as partnerships for U.S. federal income tax purposes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them of the exchange of their Senti Capital Stock for Class A Common Stock in the Business Combination or the redemption of their Class A Common Stock, as applicable.

HOLDERS OF SENTI CAPITAL STOCK OR CLASS A COMMON STOCK SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Material Tax Considerations of the Business Combination to U.S. Holders of Senti Capital Stock

The discussion under this heading, “— Material Tax Considerations of the Business Combination to U.S. Holders of Senti Capital Stock,” constitutes the opinion of Goodwin Procter LLP, insofar as it discusses the material U.S. federal income tax considerations applicable to U.S. Holders of Senti capital stock as a result of the Business Combination, based on, and subject to, customary assumptions, qualifications and limitations, and the assumptions, qualifications and limitations in this section titled “Material U.S. Federal Income Tax Consequences” and in the opinion included as Exhibit 8.1 hereto, as well as representations by Senti and DYNS.

Characterization of the Business Combination

Each of Senti and DYNS intends and expects the Business Combination to qualify as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. In the Business Combination Agreement, each of Senti and DYNS has agreed to, and to cause its affiliates to, use reasonable best

153

efforts to qualify the Business Combination as a reorganization and neither Senti nor DYNS shall take any action, or knowingly fail to take any action, that could reasonably be expected to prevent or impede such qualification. The Business Combination should qualify as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. However, the completion of the Business Combination is not conditioned on the Business Combination qualifying as a reorganization within the meaning of Section 368(a) of the Code or upon receipt of an opinion from counsel to that effect.

Senti and DYNS do not intend to seek, and have not sought, any rulings from the IRS regarding the U.S. federal income tax consequences of the Business Combination. Accordingly, there can be no assurance that the Business Combination will constitute a reorganization within the meaning of Section 368(a) of the Code or that the IRS will not assert, or that a court will not sustain, a position contrary to the conclusions set forth below.

U.S. Federal Income Tax Consequences for U.S. Holders

If the Business Combination qualifies as a reorganization within the meaning of Section 368(a) of the Code, a U.S. Holder of Senti Capital Stock will not recognize gain or loss upon the exchange of Senti Capital Stock for Class A Common Stock pursuant to the Business Combination.

A U.S. Holder’s aggregate tax basis in the shares of Class A Common Stock received in the Business Combination in exchange for Senti Capital Stock will equal the U.S. Holder’s aggregate tax basis in the shares of Senti Capital Stock surrendered in the Business Combination, and the holding period of such shares of Class A Common Stock will include the holding period of the shares of Senti capital stock surrendered in exchange therefor.

For purposes of determining the tax bases and holding periods for shares of Class A Common Stock received in the Business Combination, U.S. Holders who acquired different blocks of Senti Capital Stock at different times or for different prices must calculate their bases and holding periods in their shares of Senti Capital Stock separately for each identifiable block of such Senti Capital Stock exchanged in the Business Combination.

A U.S. Holder that receives shares of Class A Common Stock in the Business Combination and is considered a “significant holder” will be required (1) to file a statement with the holder’s U.S. federal income tax return providing certain facts pertinent to the Business Combination, including its tax basis in, and the fair market value of, the shares of Senti Capital Stock surrendered, and (2) to retain permanent records of the facts relating to the Business Combination. A “significant holder” is a U.S. Holder of Senti Capital Stock that, immediately before the Business Combination, owned at least 1% of the outstanding Senti Capital Stock by vote or value, or securities of Senti with an aggregate tax basis of $1 million or more.

U.S. Federal Income Tax Consequences if the Business Combination Failed to Qualify as a Reorganization

If the Business Combination fails to qualify as a reorganization under Section 368(a) of the Code, a U.S. Holder of Senti Capital Stock will recognize gain equal to the difference, if any, between the fair market value of the Class A Common Stock received in exchange for the Senti Capital Stock surrendered in the Business Combination and the U.S. Holder’s adjusted tax basis in such surrendered Senti Capital Stock. Any such gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period in the Senti Capital Stock surrendered in the Business Combination exceeds one year as of the closing date of the Business Combination. Long-term capital gains of non-corporate taxpayers are taxed at a reduced U.S. federal income tax rate. The deductibility of capital losses is subject to limitations. In addition, a U.S. Holder’s aggregate tax basis in the shares of Class A Common Stock received in the Business Combination would equal their fair market value at the time of the closing of the Business Combination, and the U.S. Holder’s holding period of such shares of Class A Common Stock would commence the day after the closing of the Business Combination.

Information Reporting and Backup Withholding

A U.S. Holder of Senti Capital Stock may be subject to information reporting and backup withholding for U.S. federal income tax purposes on proceeds received in connection with the Business Combination. The

154

current backup withholding rate is 24%. Backup withholding will not apply, however, to a U.S. Holder who (i) furnishes a correct taxpayer identification number and certifies the U.S. Holder is not subject to backup withholding on IRS Form W-9 or a substantially similar form or (ii) certifies that such U.S. Holder is otherwise exempt from backup withholding. U.S. Holders of shares of Senti Capital Stock should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption. If a U.S. Holder does not provide a correct taxpayer identification number on IRS Form W-9 or other proper certification, the U.S. Holder may be subject to penalties imposed by the IRS. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, provided the required information is timely furnished to the IRS.

THIS DISCUSSION OF THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE BUSINESS COMBINATION TO U.S. HOLDERS OF SENTI CAPITAL STOCK IS FOR GENERAL INFORMATION PURPOSES ONLY AND IS NOT INTENDED TO BE, AND MAY NOT BE CONSTRUED AS, TAX ADVICE. HOLDERS OF SENTI CAPITAL STOCK ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX RULES, OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION, OR UNDER ANY APPLICABLE TAX TREATY.

Material Tax Considerations Related to a Redemption of Class A Common Stock

The discussion under this heading, “— Material Tax Considerations Related to a Redemption of Class A Common Stock,” constitutes the opinion of Davis Polk & Wardwell LLP, insofar as it discusses the material U.S. federal income tax considerations applicable to U.S. Holders and Non-U.S. Holders of Class A Common Stock of a redemption of their Class A Common Stock pursuant to the exercise of their redemption right in connection with the stockholder vote regarding the Business Combination Proposal, based on, and subject to, customary assumptions, qualifications and limitations, and the assumptions, qualifications and limitations in this section titled “Material U.S. Federal Income Tax Consequences” and in the opinion included as Exhibit 8.2 hereto.

Treatment of Redemption of Class A Common Stock

Redemption of Class A Common Stock. In the event that a holder’s Class A Common Stock is redeemed pursuant to the exercise of its redemption right in connection with the stockholder vote regarding the Business Combination Proposal the treatment of the transaction for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of the Class A Common Stock under Section 302 of the Code. If the redemption qualifies as a sale of Class A Common Stock, U.S. Holders will be treated as described under “U.S. Holders — Taxation of Redemption Treated as an Exchange of Class A Common Stock” below and Non-U.S. Holders will be treated as described under “Non-U.S. Holders — Taxation of Redemption Treated as an Exchange of Class A Common Stock” below. If the redemption does not qualify as a sale of Class A Common Stock, U.S. Holders will be treated as receiving a corporate distribution with the tax consequences described below under “U.S. Holders — Taxation of Redemption Treated as a Distribution” and Non-U.S. Holders will be subject to the tax consequences described below under “— Non-U.S. Holders — Taxation of Redemption Treated as a Distribution” below. Whether a redemption qualifies for sale treatment will depend largely on the total number of Class A Common Stock treated as held by the holder relative to all of DYNS’s shares outstanding both before and after such redemption. The redemption of Class A Common Stock generally will be treated as a sale of the Class A Common Stock (rather than as a corporate distribution) if such redemption (i) is “substantially disproportionate” with respect to the holder, (ii) results in a “complete termination” of the holder’s interest in DYNS or (iii) is “not essentially equivalent to a dividend” with respect to the holder (collectively, the “302 tests”). These tests are explained more fully below.

In determining whether any of the 302 tests is satisfied, a holder takes into account not only DYNS shares actually owned by the holder, but also DYNS shares that are constructively owned by such holder under the relevant rules. A holder may constructively own, in addition to shares owned directly, shares owned by certain related

155

individuals and entities in which the holder has an interest or that have an interest in such holder, as well as any shares the holder has a right to acquire by exercise of an option. In order to meet the substantially disproportionate test, the percentage of DYNS outstanding voting shares actually and constructively owned by the holder immediately following the redemption of Class A Common Stock must, among other requirements, be less than 80% of the percentage of our outstanding voting shares actually and constructively owned by the holder immediately before the redemption. There will be a complete termination of a holder’s interest if either (i) all of the DYNS shares actually and constructively owned by the holder are redeemed or (ii) all of the DYNS shares actually owned by the holder are redeemed and the holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of shares owned by certain family members and the holder does not constructively own any other DYNS shares. The redemption of Class A Common Stock will not be essentially equivalent to a dividend if such redemption results in a “meaningful reduction” of the holder’s proportionate interest in DYNS. Whether the redemption will result in a meaningful reduction in a holder’s proportionate interest in DYNS will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.” A holder should consult with its own tax advisors as to the tax consequences of a redemption.

If none of the 302 tests are satisfied, then the redemption will be treated as a corporate distribution and the tax effects will be as described under “U.S. Holders — Taxation of Redemption Treated as a Distribution” and “Non-U.S. Holders — Taxation of Redemption Treated as a Distribution” below. After the application of those rules, any remaining tax basis of the U.S. Holder in the redeemed Class A Common Stock will be added to the holder’s adjusted tax basis in its remaining DYNS shares, or, if it has none, possibly to the U.S. Holder’s adjusted tax basis in its other shares constructively owned by such U.S. Holder.

U.S. Holders

Taxation of Redemption Treated as an Exchange of Class A Common Stock. If the redemption qualifies as an exchange of Class A Common Stock as described above under “— Treatment of Redemption of Class A Common Stock,” a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in the Class A Common Stock. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the Class A Common Stock so disposed of exceeds one year. It is unclear, however, whether the redemption rights with respect to the Class A Common Stock may suspend the running of the applicable holding period for this purpose. Long-term capital gains recognized by non-corporate U.S. Holders will be eligible to be taxed at reduced rates under current law. The deductibility of capital losses is subject to limitations.

Generally, the amount of gain or loss recognized by a U.S. Holder is an amount equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such disposition and (ii) the U.S. Holder’s adjusted tax basis in its Class A Common Stock so disposed of. A U.S. Holder’s adjusted tax basis in its Class A Common Stock generally will equal the U.S. Holder’s adjusted cost less any prior distributions treated as a return of capital for U.S. federal income tax purposes.

Taxation of Redemption Treated as a Distribution. If the redemption does not qualify as an exchange of Class A Common Stock, a U.S. Holder will generally be treated as receiving a distribution in respect of its Class A Common Stock. Such a distribution generally will be includable in a U.S. Holder’s gross income as dividend income to the extent that such distributions are paid out of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. Dividends will be taxable to a corporate U.S. Holder at regular rates and will generally be eligible for the dividends-received deduction if the requisite holding period is satisfied.

For non-corporate U.S. Holders, if the U.S. Holder satisfies certain holding period requirements and the U.S. Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property, dividends are “qualified dividend income” taxed at the preferential applicable long-term capital gain rate. It is unclear whether the redemption rights with respect to the Class A Common Stock may prevent a U.S. Holder from satisfying the applicable holding period requirements with respect to the dividends

156

received deduction or the preferential tax rate on qualified dividend income, as the case may be. If the holding period requirements are not satisfied, then non-corporate U.S. Holders may be subject to tax on such dividends at regular ordinary income tax rates instead of the preferential rate that applies to qualified dividend income.

Distributions in excess of our current or accumulated earnings and profit generally will be applied against and reduce the U.S. Holder’s basis in its Class A Common Stock (but not below zero) and, to the extent in excess of such basis, will be treated as gain from the sale or exchange of such Class A Common Stock in the manner described above under “—Taxation of Redemption Treated as an Exchange of Class A Common Stock.”

U.S. Information Reporting and Backup Withholding. Distributions with respect to the Class A Common Stock to a U.S. Holder, whether or not such distributions qualify as dividends for U.S. federal income tax purposes, and proceeds from the sale, exchange or redemption of the Class A Common Stock by a U.S. Holder generally are subject to information reporting to the IRS and possible U.S. backup withholding, unless the U.S. Holder is an exempt recipient. Backup withholding may apply to such payments if a U.S. Holder fails to furnish a correct taxpayer identification number, fails to furnish a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability, and such holder may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Non-U.S. Holders

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of Class A Common Stock that is for U.S. federal income tax purposes:

•

a non-resident alien individual;

•

a foreign corporation; or

•

a foreign estate or trust.

Redemption of Class A Common Stock. The characterization for U.S. federal income tax purposes of the redemption of a Non-U.S. Holder’s share of Class A Common Stock pursuant to the redemption provisions described in the section of this proxy statement/prospectus entitled “Special Meeting of DYNS Stockholders — Redemption Rights” generally will follow the U.S. federal income tax characterization of such a redemption as described under “ — Treatment of Redemption of Class A Common Stock” above.

Because the satisfaction of the 302 tests described above is dependent on matters of fact, withholding agents may presume, for withholding purposes, that all amounts paid to Non-U.S. Holders in connection with a redemption are treated as distributions in respect of their shares. Accordingly, a Non-U.S. Holder should expect that a withholding agent will likely withhold U.S. federal income tax on the gross proceeds payable to a Non-U.S. Holder pursuant to a redemption at a rate of 30% unless such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E, or other applicable IRS Form W-8). Each holder should consult with its own tax advisors as to the tax consequences to it of any redemption of its Class A common stock, including its ability to obtain a refund of any amounts withheld by filing an appropriate claim for a refund with the IRS in the event that the Non-U.S. Holder is not treated as receiving a dividend under the 302 tests.

157

Taxation of Redemption Treated as an Exchange of Class A Common Stock. A Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax in respect of any gain realized upon the redemption of Class A Common Stock unless:

•

the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);

•

the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

•

Class A Common Stock constitutes a U.S. real property interest (“USRPI”) by reason of DYNS’s status as a U.S. real property holding corporation (“USRPHC”) for U.S. federal income tax purposes, and certain other conditions are met.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to a U.S. Holder, unless an applicable tax treaty provides otherwise. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet above, DYNS believes that it is not and has not been at any time since its formation, and does not expect to be immediately after the Business Combination is completed, a USRPHC.

Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Taxation of Redemption Treated as a Distribution. If the redemption does not qualify as an exchange of Class A Common Stock, with respect to a Non-U.S. Holder, such holder will generally be treated as receiving a distribution in respect of Class A Common Stock. Such a distribution to the extent paid out of DYNS’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles) will constitute a dividend, first, for U.S. federal income tax purposes. Amounts not treated as a dividend for U.S. federal income tax purposes will constitute a return of capital and be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its common stock, but not below zero, and thereafter as capital gain and will be treated as described above under “—Non-U.S. Holders—Taxation of Redemption Treated as an Exchange of Class A Common Stock.”

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of Class A Common Stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that

158

the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Information Reporting and Backup Withholding. Payments of dividends on Class A Common Stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on Class A Common Stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds from a sale or other taxable disposition of Class A Common Stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds from a disposition of Class A Common Stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act. Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), payments of dividends on and the gross proceeds of dispositions of common stock of a U.S. issuer paid to (i) a “foreign financial institution” (as specifically defined in the Code) or (ii) a “non-financial foreign entity” (as specifically defined in the Code) will be subject to a withholding tax (separate and apart from, but without duplication of, the withholding tax described above) at a rate of 30%, unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied or an exemption from these rules applies. Under proposed Treasury Regulations, the preamble to which states that taxpayers may rely on them until final Treasury Regulations are issued, this withholding tax will not apply to the gross proceeds from the sale or disposition of New Senti Class A Common Stock. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above, the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Non-U.S. holders should consult their tax advisors regarding the possible implications of this withholding tax on their New Senti Class A Common Stock.

Anticipated Accounting Treatment of the Business Combination

Notwithstanding the legal form, the Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, DYNS will be treated as the acquired company for financial reporting purposes, whereas Senti will be treated as the accounting acquiror. In accordance with this accounting method, the Business Combination will be treated as the equivalent of Senti issuing stock for the net assets of DYNS, accompanied by a recapitalization. The net assets of Senti will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Business

159

Combination will be those of Senti. Senti has been determined to be the accounting acquiror for purposes of the Business Combination based on an evaluation of the following facts and circumstances:

•

if the Director Election Proposal is approved by DYNS stockholders, persons affiliated with Senti will control a majority of the governing body of New Senti;

•

Senti’s existing senior management team will comprise the senior management team of the Combined Company; and

•

Senti’s operations prior to the Business Combination will comprise the ongoing operations of New Senti.

Regulatory Matters

The Business Combination is not subject to any additional federal or state regulatory requirement or approval, except for the filings with the State of Delaware necessary to effectuate the Business Combination and the filing of required notifications and the expiration or termination of the required waiting periods under the HSR Act.

Legal proceedings in connection with the Business Combination

Required Vote of DYNS Stockholders

The approval of the Business Combination Proposal will require the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class. Additionally, the Business Combination will not be consummated if DYNS has less than $5,000,001 of net tangible assets after taking into account the redemption into cash of all Public Shares properly demanded to be redeemed by Public Stockholders.

The approval of the Business Combination Proposal is a condition to the consummation of the Business Combination. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal, as described below) will not be presented to the stockholders for a vote.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE BUSINESS COMBINATION PROPOSAL.

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of DYNS and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with your interests as a stockholder. See the section entitled “Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination” for a further discussion of these considerations.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements are provided to aid you in your analysis of the financial aspects of the Business Combination, Non-Redemption Agreements and the consummation of the PIPE Investment, which are collectively referred to as the “Transactions.”

The unaudited pro forma condensed combined financial statements have been derived from and should be read in conjunction with:

•

the accompanying notes to the unaudited pro forma condensed combined financial statements;

•

the historical audited consolidated financial statements of Senti as of and for the year ended December 31, 2021 and the related notes included elsewhere in this proxy statement/prospectus; and

•

the sections entitled “DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations”, “Senti Management’s Discussion and Analysis of Financial Condition and Results of Operations”, and other financial information relating to DYNS and Senti included elsewhere in this proxy statement/prospectus.

The unaudited pro forma condensed combined financial statements present two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1): This presentation assumes that no DYNS public stockholders exercise their right to have their DYNS Class A Common Stock converted into their pro rata share of the Trust Account and thus the full amount held in the Trust Account as of the Closing is available for the Business Combination; and

•

Assuming Maximum Redemptions (Scenario 2): This presentation assumes that 15,031,517 Public Shares are redeemed, resulting in an aggregate cash payment of approximately $150.3 million out of the Trust Account based on an assumed redemption price of $10.00 per share. This redemption figure is derived by subtracting the 7,968,483 shares that will not be redeemed by Anchor Investors (due to Non-Redemption Agreements) from the 23,000,000 Public Shares issued and outstanding as at the Record Date. After a redemption of approximately $150.3 million out of the $230.0 million Trust Account, and the $66.8 million PIPE Investment, the available cash at Closing would be approximately $146.5 million, which would be just under the condition in the Business Combination Agreement that there be at least $150.0 million in available Closing cash. As this condition is for Senti’s benefit, this Scenario assumes Senti will waive it prior to Closing, however there is no guarantee that it would and, if it did not, the Business Combination would not be consummated. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the Non-Redemption Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 15,031,517 Public Shares could be redeemed and that there may be less than approximately $146.5 million in cash available at Closing. The redemption of more than 15,031,517 Public Shares would change some of the figures presented in the maximum redemption scenario in the unaudited pro forma financial data.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1.	Description of the Transactions

On December 19, 2021, Senti entered into a definitive merger agreement with DYNS, a publicly traded special purpose acquisition company (“SPAC”). Under the terms of the proposed transaction, a wholly owned subsidiary of DYNS will merge with Senti at an estimated combined enterprise value of approximately $276.0 million. The cash components of the transaction will be funded by DYNS cash in trust of $230.0 million (assuming no redemptions) and a $66.8 million private placement of common stock at $10.00 per share from various accredited investors (the “PIPE Investment”). The Business Combination is expected to close by the end of second quarter of 2022 and remains subject to customary closing conditions.

Non-Redemption Agreement

Funds and accounts managed by the Anchor Investors, in exchange for 885,377 new securities in DYNS, have entered into the Non-Redemption Agreements, pursuant to which they have agreed not to redeem, in aggregate, 7,968,483 shares of Class A Common Stock. The new securities issued to the Anchor Investors at the closing of the Business Combination will be shares of Class A Common Stock, and the issuance of such shares will correspond with a simultaneous cancellation/forfeiture of an equivalent aggregate amount of Founder Shares held by the Sponsor, such that there is no net effect on the aggregate issued share capital of DYNS. In accordance with an amendment to the Non-Redemption Agreements entered into by DYNS, the Sponsor and the Anchor Investors on May 9, 2022, new securities will be issued to the Anchor Investors on the basis that they will receive, in shares of Class A Common Stock, 11.111% of the number of shares of Class A Common Stock which they hold at the time the Business Combination is consummated (as opposed to when the Non-Redemption Agreement was signed). The potential issuance of such shares of Class A Common Stock to the Anchor Investors is the only consideration which they will potentially receive in connection with their agreement not to redeem their Public Shares.

2.	Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of SEC Regulation S-X, as amended by the final rule, Release No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses. Release No. 33-10786 replaced the previous pro forma adjustment criteria with simplified requirements to depict the accounting for the Transactions (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably expected to occur (“Management’s Adjustments”). Management has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial statements have been identified and presented to provide relevant information necessary for an understanding of the combined company reflecting the Transactions.

The unaudited pro forma condensed combined financial statements are based on the DYNS historical financial statements, and the Senti historical consolidated financial statements as adjusted to give effect to the Transactions. The unaudited pro forma condensed combined balance sheet gives pro forma effect to the Transactions as if they had been consummated on December 31, 2021. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2021 gives effect to the Transactions as if they had occurred on January 1, 2021.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. The pro forma adjustments reflecting the Transactions are based on certain currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances. The pro forma adjustments, which are described in the accompanying notes, may be revised as additional information

166

becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible the difference may be material. Management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Transactions based on information available at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined financial statements do not give effect to any anticipated synergies, operating efficiencies, tax savings, or cost savings that may be associated with the Business Combination. DYNS and Senti have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The unaudited pro forma condensed combined financial information presents two redemption scenarios as follows:

•

Shares outstanding as presented in the unaudited pro forma condensed combined financial statements include 23,112,889 shares of New Senti Class A Common Stock to be issued to Senti stockholders, 29,465,500 shares of New Senti Class A Common Stock issued to DYNS stockholders (assuming there are no DYNS public stockholders who exercise their redemption rights) and 6,680,000 shares of New Senti Class A Common Stock issued in connection with the PIPE Investment.

Assuming no DYNS public stockholders elect to redeem their shares for cash, Senti stockholders will own approximately 39.0% of the shares of New Senti Class A Common Stock, DYNS public stockholders will own approximately 40.3% of the shares of New Senti Class A Common Stock, the PIPE Investors will own approximately 11.3% of the shares of New Senti Class A Common Stock, and the Sponsor will own approximately 9.4% of the shares of New Senti Class A Common Stock, based on the number of New Senti Class A Common Stock outstanding as of December 31, 2021.

If 15,031,517 DYNS Class A Common Stock are redeemed for cash, which assumes the maximum redemption of DYNS Class A Common Stock, Senti stockholders will own approximately 52.3% of the shares of New Senti

167

Class A Common Stock, DYNS public stockholders will own approximately 20.0% of the shares of New Senti Class A Common Stock, the PIPE Investors will own approximately 15.1% of the shares of New Senti Class A Common Stock, and the Sponsor will own approximately 12.6% of the shares of New Senti Class A Common Stock, based on the number of New Senti Class A Common Stock outstanding as of December 31, 2021.

These unaudited pro forma condensed combined financial statements and related notes have been derived from and should be read in conjunction with:

•

the accompanying notes to the unaudited pro forma condensed combined financial statements;

•

the historical audited consolidated financial statements of Senti as of and for the year ended December 31, 2021 and the related notes included elsewhere in this proxy statement/prospectus; and

•

the sections entitled “DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations”, “Senti Management’s Discussion and Analysis of Financial Condition and Results of Operation”, and other financial information relating to DYNS and Senti included elsewhere in this proxy statement/prospectus.

3.	Accounting for the Merger

Notwithstanding the legal form, the Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Under this method of accounting, DYNS will be treated as the acquired company for financial reporting purposes, whereas Senti will be treated as the accounting acquiror. In accordance with this accounting method, the Business Combination will be treated as the equivalent of Senti issuing stock for the net assets of DYNS, accompanied by a recapitalization. The net assets of Senti will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Business Combination will be those of Senti. Senti has been determined to be the accounting acquiror for purposes of the Business Combination based on an evaluation of the following facts and circumstances:

•

If the Director Election proposal is approved by DYNS stockholders, persons affiliated with Senti will control a majority of the governing body of New Senti;

•

Senti’s operations prior to the Business Combination will comprise the ongoing operations of New Senti; and

•

Senti’s existing senior management team will comprise the senior management team of the Combined Company.

4.	DYNS Class A Common Stock Issued to Senti Stockholders upon Closing of the Business Combination and the consummation of the PIPE Investment

Based on 118,224,498 shares of Senti Common Stock outstanding after conversion of the preferred stock into common stock and immediately prior to the closing of the Transactions, the estimated Exchange Ratio (as defined in the section of this proxy statement / prospectus entitled “Frequent Used Terms”) determined in accordance with the

168

terms of the Merger Agreement is approximately 0.1955¹, which means New Senti expects to issue approximately 23,112,889 shares of New Senti Common Stock in the Business Combination, determined as follows:


	Number of Senti shares as of December 31, 2021		Unvested restricted common stock subject to repurchase reclassed to Common Stock from January 1 to March 31, 2022			Vested options exercised into common stock from January 1 to March 31, 2022		Number of Senti shares as of March 31, 2022

Preferred stock		99,734,543							99,734,543

Assumed Exchange Ratio									0.1955

Estimated shares of New Senti common stock issued to Senti Stockholders upon closing of the Transactions²									23,112,889

5.	Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet

The pro forma notes and adjustments, based on preliminary estimates that could change materially as additional information is obtained, are as follows:

Pro forma notes:

(A)

Derived from the audited consolidated balance sheet of DYNS as of December 31, 2021.

(B)

Derived from the audited consolidated balance sheet of Senti as of December 31, 2021.

Pro forma Transaction Accounting Adjustments:

To reflect the release of investments from the trust account to cash and cash equivalents, assuming no DYNS public stockholders exercise their right to have their DYNS Class A Common Stock redeemed for their pro rata share of the trust account.

Exchange Ratio is calculated pursuant to the Business Combination Agreement by dividing the Equity Value Per Share by the DYNS Share Value, as each of those terms is defined in the Business Combination Agreement. DYNS Share Value is equal to $10.00. Equity Value Per Share is determined by dividing the Equity Value by the Fully Diluted Company Capitalization, again, as each of those terms is defined in the Business Combination Agreement. The Equity Value is $240,000,000. The Fully Diluted Company Capitalization is the sum of (x) the aggregate number of shares of Senti common stock outstanding as of immediately prior to the Effective Time (including the Senti preferred stock on an as-converted basis), or 118,224,498 shares, and (y) the aggregate number of shares of Senti common stock subject to Senti options (on a net exercise basis) as of immediately prior to the Effective Time (excluding any shares of Senti common stock subject to options issued under the Incentive Plan at or prior to Closing), or 4,512,790 shares, giving a total of 122,737,288 shares. Therefore, the Equity Value Per Share is approximately $1.955 (i.e. $240,000,000/ 122,737,288) and the Exchange ratio is approximately 0.1955 (i.e. $1.955 / $10.00).

²	Calculated by multiplying the “Senti preferred and common stock outstanding prior to the closing of the Transactions,” or 118,224,498 shares, by the assumed Exchange Ratio of 0.1955.

169

To reflect the payment of DYNS’s deferred underwriting fee payable of $7.1 million of costs incurred in connection with the DYNS initial public offering which is payable upon completion of the Business Combination. The payment of $7.1 million has been recorded as a reduction of $7.1 million to deferred underwriting fee payable.

To reflect the payment of DYNS’s accrued expenses and other current liabilities of $3.1 million, accounts payable of $40 thousand, franchise taxes of $164 thousand and a reclassification of deferred transaction cost of $0.6 million that are deemed to be direct and incremental costs of the Business Combination from prepaid expenses and other current assets and other long-term assets to additional paid-in capital.

To reflect the payment of DYNS total estimated advisory, legal, accounting and auditing fees and other professional fees of $0.1 million that are deemed to be direct and incremental costs of the Business Combination and the payment of $4.7 million of DYNS’s additional transaction costs that are not directly attributable to the Business Combination and are non-recurring items. The payment of $0.1 million of costs directly attributable to the Business Combination have been recorded as a reduction of $0.1 million to additional paid-in capital. The payment of $4.7 million of additional transaction costs has been recorded as an increase to accumulated deficit (see Note 6(e) below).

To reflect the payment of Senti total estimated advisory, legal, accounting and auditing fees and other professional fees of $5.7 million that are deemed to be direct and incremental costs of the Business Combination. The payment of $5.7 million of costs directly attributable to the Business Combination have been recorded as a reduction of $5.7 million to additional paid-in capital, a reduction of $1.3 million to accrued expenses and other current liabilities, a reduction of $0.1 million to accounts payable and a reduction of $1.4 million to prepaid expenses and other current assets.

To reflect the issuance of an aggregate of 6,680,000 shares of New Senti Common Stock in the PIPE Investment at a price of $10.00 per share, for proceeds of $66.8 million and to record the fees associated with the consummation of the PIPE Investment in the amount of $2.7 million. The issuance of 6,680,000 shares was recorded as an increase of $66.8 million to cash and cash equivalents, an increase to common stock of $1 thousand and an increase to additional paid-in capital in amount of $66.8 million. The PIPE fees in the amount of $2.7 million were recorded as a decrease to cash and cash equivalents and a decrease to additional paid-in capital.

To reflect the reclassification of Class A Common Stock subject to redemption of $230.0 million to New Senti Class A Common Stock of $2 thousand and additional paid-in capital $230.0 million, in Scenario 1, which assumes no DYNS public stockholders exercise their redemption rights.

To reflect, in Scenario 2, the assumption that DYNS public stockholders exercise their redemption rights with respect to a maximum of 15,031,517 DYNS Class A Common Stock prior to the consummation of the Business Combination at a redemption price of approximately $10.00 per share, or $150.3 million in cash. The maximum number of shares of 15,031,517 DYNS Class A Common Stock will result in a cash balance of $146.5 million.

To reflect the recapitalization of Senti through the contribution of all outstanding common stock and preferred stock of Senti to DYNS and the issuance of 23,112,889 shares of New Senti Class A Common Stock and the elimination of the accumulated deficit of DYNS, the accounting acquiree. As a result of the recapitalization, Senti Common Stock of $1 thousand, Senti redeemable convertible preferred stock of $171.8 million and DYNS accumulated deficit of $22.4 million including the transaction adjustment of $8.9 million described in Note 5(k) were derecognized. The shares of New Senti Common Stock issued in exchange for Senti’s capital were recorded as increase to common stock of $2 thousand and increase to additional paid-in capital in amount of $149.4 million.

To reflect the cancellation of 885,377 Class B common stock of DYNS in order to issue 885,377 Class A common stock of DYNS to the Anchor Investors as discussed in Note 1 above and Note 5(k) below.

170

To reflect the issuance of 885,377 Class A Common Stock of DYNS to the Anchor Investors. To induce Anchor Investors, to not exercise their redemption rights in respect of the Class A Common Stock in connection with the pending merger with Senti, DYNS entered into the non-redemption agreements with Anchor Investors. Pursuant to the non-redemption agreements, concurrently with the execution of the Merger Agreement, the Sponsor will agree to forfeit to DYNS certain Class B Common Stock which it holds, and DYNS will agree to cancel such Class B Common Stock of the Sponsor and concurrently issue to the Anchor Investors an equivalent number of shares of Class A Common Stock, thereby potentially increasing the Anchor Investors’ ownership interest in New Senti. The potential issuance of such shares of Class A Common Stock to the Anchor Investors is the only consideration which they potentially receive in connection with their agreement not to redeem their Public Shares. Based on the price of $10.00 per share this transaction results in an increase to common stock of $88, increase to additional paid-in capital of $8.9 million and increase to accumulated deficit of $8.9 million (see Note 6(b) below).

To reflect the conversion of the remaining DYNS Class B Common Stock (after the cancellation of 885,377 DYNS Class B Common Stock as discussed in Note 5(j)) to DYNS Class A Common Stock.

To reflect the reclassification of DYNS Class A Common Stock including amounts discussed in Note 5(k) to New Senti Class A Common Stock.

To reflect an increase of 881,993 shares of Senti Common Stock due to the exercise of vested options in the period from January 1 to March 31, 2022, resulting in an increase of $422 thousand to cash and cash equivalents, an increase of $88 to common stock and an increase of $422 thousand to additional paid-in capital (see Note 4).

6.	Adjustments to Unaudited Pro Forma Condensed Combined Statement of Operations

The pro forma notes and adjustments, based on preliminary estimates that could change materially as additional information is obtained, are as follows:

Pro forma notes:

(A)

Derived from the audited consolidated statement of operations of DYNS for the period from March 1, 2021 (inception) through December 31, 2021.

(B)

Derived from the audited consolidated statement of operations of Senti for the year ended December 31, 2021.

Pro forma Transaction Accounting Adjustments:

To reflect an adjustment to eliminate interest and dividend income earned on investments held in the trust account as if the Business Combination had occurred on January 1, 2021.

To reflect expense associated with the issuance of the Class A Common Stock equal to $8.9 million in accordance with the non-redemption agreements (see Notes 5(j) and 5(k) above).

To reflect an adjustment to eliminate the change in preferred stock tranche liability as it is assumed that the preferred stock would have been converted to Senti Common Stock and then to shares of New Senti Common Stock as if the Business Combination had occurred on January 1, 2021.

To reflect an estimated compensation expense associated with the stock options that were granted under new equity incentive plan as if the Business Combination had occurred on January 1, 2021. The compensation expense was estimated on a tranche-by-tranche basis. The estimated grant date fair value was determined as of December 20, 2021, with the exception of modified awards that used the estimated grant date fair value as of February 12, 2022. The number of shares that become exercisable

171

for certain key executives decreases depending on the number of redeemed DYNS Class A Common Stock as of the Closing. The decrease in the number of exercisable shares only reduces general and administrative compensation expenses in the maximum redemption scenario. The number of stock options under the two redemption scenarios are presented as follows:


	Number of stock options under the new equity incentive plan
	Scenario 1 Assuming No Redemptions for Cash		Scenario 2 Assuming Maximum Redemptions for Cash
Stock options that are contingent on the consummation of the Business Combination and a four years service period		42,927,654		35,627,801
Stock options that are contingent on the consummation of the Business Combination, market conditions, and an estimated two years service period		3,093,776		1,564,391

To reflect additional transaction costs of $4.7 million within general and administrative expense of DYNS (see Note 5(d) above).

The pro forma basic and diluted net loss per share amounts presented in the unaudited pro forma condensed combined statements of operations are based upon the number of New Senti shares outstanding as if the Transactions occurred on January 1, 2021. The calculation of weighted-average shares outstanding for pro forma basic and diluted net loss per share assumes that the shares issuable in connection with the Transactions have been outstanding for the entirety of the period presented.

Pro forma weighted-average common shares outstanding—basic and diluted is calculated as follows:


	Year Ended December 31, 2021
	Scenario 1 (Assuming No Redemptions for Cash)			Scenario 2 (Assuming Maximum Redemptions for Cash)
Weighted-average shares calculation—basic and diluted
New Senti Class A common stock owned by Sponsors (1)		5,580,123			5,580,123

173

PROPOSAL 2: THE CHARTER AMENDMENT PROPOSAL

The Charter Amendment Proposal, if approved, will approve (among others) the following amendments to the Current Charter to:

•

change the name of the new public entity to “Senti Biosciences, Inc.” as opposed to “Dynamics Special Purpose Corp.”;

•

increase DYNS’s capitalization so that it will have 500,000,000 authorized shares of a single class of common stock and 10,000,000 authorized shares of preferred stock, as opposed to DYNS having 100,000,000 authorized shares of Class A Common Stock, 10,000,000 authorized shares of Class B Common Stock and 1,000,000 authorized shares of preferred stock;

•

require that the removal of any director be only for cause and by the affirmative vote of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote generally in the election of directors;

•

require that certain amendments to provisions of the Proposed Charter will require the approval of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote on such amendment and of each class entitled to vote thereon as a class;

•

remove the provision allowing stockholders to act by written consent in lieu of holding a meeting of stockholders; and

•

make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the Initial Public Offering and to remove from the Proposed Charter the various provisions applicable only to special purpose acquisition companies.

In the judgment of the Board, the Charter Amendment Proposal is desirable for the following reasons:

•

the name of the new public entity is desirable to reflect the Business Combination with Senti and the combined business going forward;

•

the greater number of authorized number of shares of capital stock is desirable for the Combined Company to have enough additional authorized shares for financing its business, for acquiring other businesses, for forming strategic partnerships and alliances and for stock dividends and stock splits and to issue upon exercise of equity grants currently outstanding or made under the Incentive Plan (assuming it is approved at the Special Meeting);

•

the single class of common stock is desirable because all shares of Class B Common Stock will be exchanged for Class A Common Stock upon consummation of the Business Combination, and because it will allow the Combined Company to have a streamlined capital structure;

•

it is desirable to increase the voting threshold required to remove a director from the Combined Company board and amend certain provisions of the Current Charter, and to remove the provision allowing stockholder action by written consent, in order to help facilitate corporate governance stability by requiring broad stockholder consensus to effect corporate governance changes, protect minority stockholder interests and enable the Combined Company board to preserve and maximize value for all stockholders in the context of an opportunistic and unsolicited takeover attempt; and

•

it is desirable to delete the provisions that relate to the operation of DYNS as a blank check company prior to the consummation of its initial business combination because they would not be applicable after the Business Combination (such as the obligation to dissolve and liquidate if a business combination is not consummated within a certain period of time).

174

fiduciary obligations, for example, the board of New Senti was to determine that a takeover proposal was not in the best interests of New Senti, shares could be issued by the board without stockholder approval in one or more private placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquiror or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. The authorization of additional shares will, however, enable New Senti to have the flexibility to authorize the issuance of shares in the future for financing its business, acquiring other businesses, forming strategic partnerships and alliances and stock dividends and stock splits. DYNS currently has no such plans, proposals or arrangements, written or otherwise, to issue any of the additional authorized shares for such purposes.

The Charter Amendment Proposal, if approved, will also approve amended bylaws for the Combined Company (a copy of which is attached to this proxy statement/ prospectus at Annex B).

Under the Business Combination Agreement, the approval of the Charter Amendment Proposal is a condition to the adoption of the Business Combination Proposal and vice versa. Accordingly, if the Business Combination Proposal is not approved, the Charter Amendment Proposal will not be presented at the Special Meeting.

The approval of the Charter Amendment Proposal requires the affirmative vote of a majority of the issued and outstanding shares of each of the Class A Common Stock and Class B Common Stock, voting separately, as well as the vote of a majority of the issued and outstanding shares of Class A Common Stock and Class B Common Stock, voting together as a single class. Accordingly, a DYNS stockholder’s failure to vote by proxy or to vote in person (which would include presence at a virtual meeting) at the Special Meeting or an abstention will have the same effect as a vote “AGAINST” the Charter Amendment Proposal.

A copy of the Proposed Charter, as will be in effect assuming approval of the Charter Amendment Proposal and upon consummation of the Business Combination and filing with the Delaware Secretary of State, is attached to this proxy statement/prospectus as Annex B. The proposed amended bylaws for the Combined Company are also attached to this proxy statement/prospectus as Annex B.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE CHARTER AMENDMENT PROPOSAL.

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of DYNS and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with or be in addition to your interests as a stockholder. See the section entitled “Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination” for a further discussion of these considerations.

175

PROPOSAL 3: THE ADVISORY CHARTER AMENDMENT PROPOSALS

In connection with the Business Combination, DYNS is asking its stockholders to vote upon, on a non-binding advisory basis, proposals to approve certain governance provisions contained in the Proposed Charter. This separate vote is not otherwise required by Delaware law separate and apart from the Charter Amendment Proposal. Pursuant to SEC guidance, DYNS is submitting these provisions to its stockholders separately for approval, allowing stockholders the opportunity to present their separate views on important governance provisions. However, the stockholder votes regarding these proposals are advisory votes, and are not binding on DYNS or the Board (separate and apart from the approval of the Charter Amendment Proposal). In the judgment of the Board, these provisions are necessary to adequately address the needs of the Combined Company. Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Amendment Proposals (separate and apart from approval of the Charter Amendment Proposal).

DYNS stockholders will be asked to approve, on a non-binding advisory basis, the following material differences between the Proposed Charter and the Current Charter, which are being presented as seven separate sub-proposals (the “Advisory Charter Amendment Proposals”):

•

Advisory Charter Amendment Proposal A — to change the corporate name of the Combined Company to “Senti Biosciences, Inc.” on and from the time of the Business Combination;

•

Advisory Charter Amendment Proposal B — to increase the authorized shares of common stock of the Combined Company to 500,000,000 shares;

•

Advisory Charter Amendment Proposal C — to increase the authorized shares of preferred stock that the Combined Company’s board of directors could issue to 10,000,000 shares;

•

Advisory Charter Amendment Proposal D — to provide that certain named individuals be elected to serve as Class I, Class II and Class III directors to serve staggered terms on the board of directors of New Senti until their respective successors are duly elected and qualified, or until their earlier resignation, death, or removal and to provide that the removal of any director be only for cause (and by the affirmative vote of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote generally in the election of directors);

•

Advisory Charter Amendment Proposal E — to provide that certain amendments to provisions of the Proposed Charter will require the approval of at least 75% of the Combined Company’s then-outstanding shares of capital stock entitled to vote on such amendment and of each class entitled to vote thereon as a class;

•

Advisory Charter Amendment Proposal F — to make the Combined Company’s corporate existence perpetual instead of requiring DYNS to be dissolved and liquidated 24 months following the closing of the Initial Public Offering, and to remove from the Proposed Charter the various provisions applicable only to special purpose acquisition companies; and

•

Advisory Charter Amendment Proposal G — to remove the provisions that allow stockholders to act by written consent as opposed to holding a stockholders meeting.

Reasons for the Charter Amendments

In the judgment of the Board, the amendments to the Current Charter are desirable for the following reasons:

•

the name of the new public entity is desirable to reflect the Business Combination with Senti and the combined business going forward;

•

176

to issue upon exercise of the equity grants currently outstanding or made under the Incentive Plan (assuming it is approved at the Special Meeting);

•

Notwithstanding the foregoing, certain of the Proposed Charter amendments may make it more difficult or discourage an attempt to obtain control of New Senti and thereby protect continuity of or entrench its management, which may adversely affect the market price of New Senti’s securities. If, in the due exercise of its fiduciary obligations, for example, the board of New Senti was to determine that a takeover proposal was not in the best interests of New Senti, shares could be issued by the board without stockholder approval in one or more private placements or other transactions that might prevent or render more difficult or make more costly the completion of any attempted takeover transaction by diluting voting or other rights of the proposed acquiror or insurgent stockholder group, by creating a substantial voting bloc in institutional or other hands that might support the position of the incumbent board of directors, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. The authorization of additional shares will, however, enable New Senti to have the flexibility to authorize the issuance of shares in the future for financing its business, acquiring other businesses, forming strategic partnerships and alliances and stock dividends and stock splits. DYNS currently has no such plans, proposals or arrangements, written or otherwise, to issue any of the additional authorized shares for such purposes.

The approval of each of the Advisory Charter Amendment Proposals requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF EACH OF THE ADVISORY CHARTER AMENDMENT PROPOSALS.

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of DYNS and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with or be in addition to your interests as a stockholder. See the section entitled “Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination” for a further discussion of these considerations.

177

PROPOSAL 4: THE NASDAQ STOCK ISSUANCE PROPOSAL

For purposes of complying with Rule 5635(a), (b) and (d) of the Nasdaq Stock Market Listing Rules, stockholders of DYNS are being asked to approve the issuance of up to 26,000,000 shares of Class A Common Stock in connection with the Business Combination and the issuance of an aggregate of 6,680,000 shares of Class A Common Stock to the PIPE Investors pursuant to the Subscription Agreements.

Under Nasdaq Rule 5635(a), stockholder approval is required prior to the issuance of securities in connection with the acquisition of another company if such securities are not issued in a public offering and (i) have, or will have upon issuance, voting power equal to or in excess of 20% of the voting power outstanding before the issuance of common stock (or securities convertible into or exercisable for common stock); or (ii) the number of shares of common stock to be issued is or will be equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the stock or securities. Collectively, the Business Combination Consideration and the Contingency Consideration (which together comprise 26,000,000 shares of Class A Common Stock), and the shares being issued to the PIPE Investors, will exceed 20% of the outstanding DYNS Common Stock and 20% of the voting power, in each case outstanding before the issuance of such shares in connection with the Business Combination and the PIPE Investment.

Under Nasdaq Rule 5635(b), stockholder approval is required when any issuance or potential issuance will result in a “change of control” of the issuer. Although Nasdaq has not adopted any rule on what constitutes a “change of control” for purposes of Rule 5635(b), Nasdaq has previously indicated that the acquisition of, or right to acquire, by a single investor or affiliated investor group, as little as 20% of the common stock (or securities convertible into or exercisable for common stock) or voting power of an issuer could constitute a change of control. Under Nasdaq Rule 5635(b), the issuance of the Business Combination Consideration and the Contingency Consideration and/or the shares in the PIPE Investment will result in a “change of control” of DYNS.

Under Nasdaq Listing Rule 5635(d), stockholder approval is required for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of common stock (or securities convertible into or exercisable for common stock) at a price that is less than the lower of (i) the closing price immediately preceding the signing of the binding agreement or (ii) the average closing price of the common stock for the five trading days immediately preceding the signing of the binding agreement, if the number of shares of common stock (or securities convertible into or exercisable for common stock) to be issued equals 20% or more of the common stock, or 20% or more of the voting power, outstanding before the issuance. Because shares of Class A Common Stock will be issued in exchange for all of the equity interests of Senti, the deemed issuance price of the shares of Class A Common Stock may be less than the lower of (i) the closing price immediately preceding the signing of the Business Combination Agreement or (ii) the average closing price of the Class A Common Stock for the five trading days immediately preceding the signing of the Business Combination Agreement. If the Business Combination Proposal is approved, the issuance of the shares of Class A Common Stock will exceed 20% of the shares of DYNS Common Stock currently outstanding. Because the issuance price may be deemed to be below the lower of (i) the closing price immediately preceding the signing of the Business Combination Agreement or (ii) the average closing price of the Class A Common Stock for the five trading days immediately preceding the signing of the Business Combination Agreement, the Nasdaq Rules may require that DYNS obtain stockholder approval of the issuance of the shares of Class A Common Stock in connection with the consummation of the Business Combination.

In addition, because the shares of Class A Common Stock issuable to the PIPE Investors (1) will be issued at a price that is less than the lower of (i) the closing price immediately preceding the signing of the Business Combination Agreement or (ii) the average closing price of the Class A Common Stock for the five trading days immediately preceding the signing of the Business Combination Agreement, and (2) will constitute more than 20% of the outstanding shares of DYNS Common Stock and more than 20% of outstanding voting power of DYNS Common Stock prior to such issuance, DYNS is required to obtain stockholder approval of such issuance pursuant to Nasdaq Rule 5635(d).

178

As a result of the foregoing, DYNS is required to obtain stockholder approval pursuant to The Nasdaq Stock Market Listing Rule 5635. For a summary of the Subscription Agreements, please see the section entitled “Proposal 1: The Business Combination Proposal — Related Agreements — Subscription Agreements.” DYNS stockholders should read carefully this proxy statement/prospectus in its entirety for more detailed information regarding the Subscription Agreements. You are urged to read carefully the form of Subscription Agreement in its entirety before voting on this Proposal.

The approval of the Nasdaq Stock Issuance Proposal requires the affirmative vote of the holders of a

majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote

thereon at the Special Meeting, voting together as a single class.

If the Business Combination Proposal is not approved, the Nasdaq Stock Issuance Proposal will not be presented at the Special Meeting.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” THE NASDAQ STOCK ISSUANCE PROPOSAL.

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of DYNS and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with or be in addition to your interests as a stockholder. See the section entitled “Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination” for a further discussion of these considerations.

179

PROPOSAL 5: THE DIRECTOR ELECTION PROPOSAL

Election of Directors

At the Special Meeting, it is proposed that seven directors will be elected to be the directors of New Senti upon consummation of the Business Combination. The Combined Company’s board of directors will reclassify. The term of office of the Class I directors will expire at the first annual meeting of stockholders following the initial reclassification of the board of directors and Class I directors will be elected for a full term of three years. At the second annual meeting of stockholders following such reclassification, the term of office of the Class II directors will expire and Class II directors will be elected for a full term of three years. At the third annual meeting of stockholders following such reclassification, the term of office of the Class III directors will expire and Class III directors will be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors will be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting. Subject to any limitations imposed by applicable law and subject to the special rights of the holders of any series of preferred stock to elect directors, any vacancy occurring in the New Senti Board for any reason, and any newly created directorship resulting from any increase in the authorized number of directors, will, unless (a) New Senti’s board of directors determines by resolution that any such vacancies or newly created directorships will be filled by the stockholders, or (b) as otherwise provided by law, be filled only by the affirmative vote of a majority of the directors then in office, even if less than a quorum, or by a sole remaining director, and not by the stockholders.

It is proposed that the Company’s board of directors consist of the following directors:

•

Class I directors: Timothy Lu, Edward Mathers and Omid Farokhzad.

•

Class II directors: David Epstein and Susan Berland.

•

Class III directors: James (Jim) Collins and Brenda Cooperstone.

Information regarding each nominee is set forth in the section entitled “Management of the Combined Company.”

Under Delaware law and DYNS’s bylaws, the election of directors requires a plurality vote of the shares of DYNS Class B Common Stock cast in respect of that Proposal and entitled to vote thereon at the Special Meeting. “Plurality” means that the individuals who receive the largest number of votes cast “FOR” are elected as directors. Consequently, any shares not voted “FOR” a particular nominee (whether as a result of an abstention, a direction to withhold authority or a broker non-vote) will not be counted in the nominee’s favor.

Unless authority is withheld or the shares are subject to a broker non-vote, the proxies solicited by the Board will be voted “FOR” the election of these nominees. In case any of the nominees becomes unavailable for election to the board of directors, an event that is not anticipated, the persons named as proxies, or their substitutes, will have full discretion and authority to vote or refrain from voting for any other candidate in accordance with their judgment.

If the Business Combination Proposal is not approved, the Director Election Proposal will not be presented at the Special Meeting.

Following consummation of the Business Combination, the election of directors of the Combined Company will be governed by the Proposed Charter, the New Senti’s amended bylaws and the laws of the State of Delaware.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS THAT DYNS STOCKHOLDERS VOTE “FOR” EACH OF THE NOMINEES LISTED IN THIS PROXY STATEMENT/PROSPECTUS.

180

The existence of financial and personal interests of one or more of DYNS’s directors may result in a conflict of interest on the part of such director(s) between what he, she or they may believe is in the best interests of DYNS and its stockholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that stockholders vote for the Proposals. In addition, DYNS’s directors and officers have interests in the Business Combination that may conflict with or be in addition to your interests as a stockholder. See the section entitled “Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination” for a further discussion of these considerations.

181

PROPOSAL 6: THE INCENTIVE PLAN PROPOSAL

Overview

In this Incentive Plan Proposal, DYNS is asking its stockholders to approve the Incentive Plan. DYNS’s board of directors will adopt the Incentive Plan prior to the Special Meeting, in substantially the form of Annex C attached hereto, subject to stockholder approval at the Special Meeting. If stockholders approve this proposal, the Incentive Plan will become effective on the consummation of the Business Combination.

The Incentive Plan is intended to replace the Senti Biosciences, Inc. 2016 Stock Incentive Plan (the “2016 Plan”). Following the Business Combination, no additional stock awards will be granted under the 2016 Plan, although all outstanding stock options granted under the 2016 Plan immediately prior to the Business Combination will be assumed by DYNS (the “Rollover Options”) and continue to be subject to the terms and conditions as set forth in the agreements evidencing such stock options and the terms of the 2016 Plan (subject to conversion based on the Exchange Ratio, except for terms rendered imperative by the Business Combination).

General Information

The purpose of the Incentive Plan is to provide a means whereby New Senti can secure and retain the services of employees, directors and consultants, to provide incentives for such persons to exert maximum efforts for the success of New Senti and its affiliates and to provide a means by which such persons may be given an opportunity to benefit from increases in value of New Senti common stock through the granting of awards under the Incentive Plan.

Approval of the Incentive Plan by DYNS’s stockholders is required, among other things, in order to comply with stock exchange rules requiring stockholder approval of equity compensation plans and allow the grant of incentive stock options (“ISOs”) under the Incentive Plan. If this Incentive Plan Proposal is approved by DYNS’s stockholders, the Incentive Plan will become effective as of the date of the closing of the Business Combination. In the event that the stockholders do not approve this proposal, the Incentive Plan will not become effective.

New Senti’s equity compensation program, as implemented under the Incentive Plan, will allow New Senti to be competitive with comparable companies in its industry by giving it the resources to attract and retain talented individuals to achieve its business objectives and build stockholder value. It is critical to New Senti’s long-term success that the interests of employees and other service providers are tied to its success as “owners” of the business. Approval of the Incentive Plan will allow New Senti to grant stock options and other equity awards at levels it determines to be appropriate in order to attract new employees and other service providers, retain existing employees and service providers and to provide incentives for such persons to exert maximum efforts for New Senti’s success and ultimately increase stockholder value. The Incentive Plan allows New Senti to utilize a broad array of equity incentives with flexibility in designing equity incentives, including traditional stock option grants, stock appreciation rights, restricted stock awards, restricted stock unit awards, other stock awards and performance awards to offer competitive equity compensation packages in order to retain and motivate the talent necessary for New Senti.

If the request to approve the Incentive Plan is approved by DYNS stockholders, there will be a number of shares of New Senti Common Stock equal to 22% of the aggregate number of shares of New Senti Common Stock issued and outstanding immediately after the Closing, less any New Senti Common Stock the subject of Closing Option Awards (as defined in the Business Combination Agreement), available for grant under the Incentive Plan. Based on the assumed exchange ratio of 0.1955 described herein, the number of shares authorized for issuance under the Incentive Plan upon the Closing is expected to be approximately 4,040,000 shares of New Senti Common Stock (assuming no redemptions of Public Shares from the Trust Account), but the exact number will not be known until the Business Combination is consummated. In addition, as further described below under “—Description of the Incentive Plan—Authorized Shares,” the share reserve is subject to annual increases each

182

January 1 of up to 5% of the shares of New Senti common stock (or a lesser number determined by New Senti’s board of directors). The DYNS board of directors believes this pool size is necessary to provide sufficient reserved shares for a level of grants that will attract, retain, and motivate employees and other participants.

Description of the Incentive Plan

A summary description of the material features of the Incentive Plan is set forth below. The following summary does not purport to be a complete description of all the provisions of the Incentive Plan and is qualified by reference to the Incentive Plan, the form of which is attached to this proxy statement/prospectus as Annex C and incorporated by reference in its entirety. DYNS stockholders should refer to the Incentive Plan for more complete and detailed information about the terms and conditions of the Incentive Plan.

Eligibility. Any individual who is an employee of New Senti or any of its affiliates, or any person who provides services to New Senti or its affiliates, including members of the New Senti Board, is eligible to receive awards under the Incentive Plan at the discretion of the plan administrator. If this Proposal is approved by the stockholders, all of New Senti’s employees, directors and consultants will be eligible to receive awards following the closing of the Business Combination. When the Business Combination closes, New Senti is expected to have approximately ninety-three employees, six non-employee directors and nine consultants who will be eligible to receive awards under the Incentive Plan.

Awards. The Incentive Plan provides for the grant of ISOs, within the meaning of Section 422 of the Code, to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards and other forms of awards to employees, directors and consultants, including employees and consultants of New Senti’s affiliates.

Authorized Shares. Subject to adjustment as set forth in the Incentive Plan, the maximum number of shares of New Senti Common Stock that may be issued under the Incentive Plan shall be equal to 22% of the aggregate number of shares of New Senti Common Stock issued and outstanding immediately after the Closing, less any New Senti Common Stock the subject of Closing Option Awards (as defined in the Business Combination Agreement), plus any shares underlying the Rollover Options that expire or terminate without being exercised or otherwise issued in full. Based on the assumed exchange ratio of 0.1955 described herein, the number of shares authorized for issuance under the Incentive Plan upon the Closing is expected to be approximately 4,040,000 shares of New Senti Common Stock (assuming no redemptions of Public Shares from the Trust Account), but the exact number will not be known until the Business Combination is consummated. In addition, the number of shares of New Senti Common Stock reserved for issuance under the Incentive Plan will automatically increase on January 1 of each year, starting on January 1, 2023 through January 1, 2032, in an amount equal to (1) 5% of the total number of shares of New Senti Common Stock on December 31 of the preceding year, or (2) a lesser number of shares of New Senti Common Stock determined by the New Senti Board prior to the date of the increase. The maximum number of shares of New Senti Common Stock that may be issued on the exercise of ISOs under the Incentive Plan will not be known until the Business Combination is consummated but will be commensurate with the number of shares authorized under the Incentive Plan. As of the Record Date, the closing price of Class A Common Stock as reported on the Nasdaq was $9.94 per share.

Shares subject to stock awards granted under the Incentive Plan that expire or terminate without being exercised or otherwise issued in full or that are paid out in cash rather than in shares do not reduce the number of shares available for issuance under the Incentive Plan. Shares withheld under a stock award to satisfy the exercise, strike or purchase price of a stock award or to satisfy a tax withholding obligation do not reduce the number of shares available for issuance under the Incentive Plan. If any shares of New Senti Common Stock issued pursuant to a stock award or Rollover Option are forfeited back to or repurchased or reacquired by New Senti (1) because of the failure to vest, (2) to satisfy the exercise, strike or purchase price, or (3) to satisfy a tax withholding obligation in connection with an award, the shares that are forfeited or repurchased or reacquired will revert to and again become available for issuance under the Incentive Plan.

183

Non-Employee Director Compensation Limit. The aggregate value of all compensation granted or paid to any non-employee director with respect to any calendar year, including awards granted and cash fees paid to such non-employee director, will not exceed (1) $750,000 in total value or (2) if such non-employee director is first appointed or elected to New Senti’s board of directors during such calendar year, $1,000,000 in total value, in each case, calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes.

Plan Administration. The New Senti Board, or a duly authorized committee thereof, will administer the Incentive Plan and is referred to as the “plan administrator” herein. New Senti’s board of directors (or committee thereof) may also delegate to one or more of New Senti’s officers the authority to (1) designate employees (other than officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards. Under the Incentive Plan, the New Senti Board (or an authorized delegate) has the authority to determine award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value, and the provisions of each stock award, including the period of exercisability and the vesting schedule applicable to a stock award.

Under the Incentive Plan, the New Senti Board also generally has the authority to effect, without the approval of stockholders but with the consent of any materially adversely affected participant, (1) the reduction of the exercise, purchase, or strike price of any outstanding option or stock appreciation right; (2) the cancellation of any outstanding option or stock appreciation right and the grant in substitution therefore of other awards, cash, or other consideration; or (3) any other action that is treated as a repricing under GAAP.

Stock Options. ISOs and NSOs are granted under stock option agreements adopted by the plan administrator. The plan administrator determines the exercise price for stock options, within the terms and conditions of the Incentive Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of a share of New Senti common stock on the date of grant. Options granted under the Incentive Plan vest at the rate specified in the stock option agreement as determined by the plan administrator.

The plan administrator determines the term of stock options granted under the Incentive Plan, up to a maximum of 10 years. Unless the terms of an optionholder’s stock option agreement provide otherwise or as otherwise provided by the plan administrator, if an optionholder’s service relationship with New Senti or any of New Senti’s affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. This period may be extended in the event that exercise of the option is prohibited by applicable securities laws. Unless the terms of an optionholder’s stock option agreement provide otherwise or as otherwise provided by the plan administrator, if an optionholder’s service relationship with New Senti or any of New Senti’s affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 18 months following the date of death. Unless the terms of an optionholder’s stock option agreement provide otherwise or as otherwise provided by the plan administrator, if an optionholder’s service relationship with New Senti or any of New Senti’s affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of New Senti Common Stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of New Senti common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO or (5) other legal consideration approved by the plan administrator.

184

Unless the plan administrator provides otherwise, options and stock appreciation rights generally are not transferable except by will or the laws of descent and distribution. Subject to approval of the plan administrator or a duly authorized officer, an option may be transferred pursuant to a domestic relations order.

Tax Limitations on ISOs. The aggregate fair market value, determined at the time of grant, of New Senti Common Stock with respect to ISOs that are exercisable for the first time by an award holder during any calendar year under all of New Senti’s stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of New Senti’s total combined voting power or that of any of New Senti’s parent or subsidiary corporations unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Unit Awards. Restricted stock unit awards are granted under restricted stock unit award agreements adopted by the plan administrator. Restricted stock unit awards may be granted in consideration for any form of legal consideration (including services) that may be acceptable to the plan administrator and permissible under applicable law. A restricted stock unit award may be settled by cash, delivery of shares of New Senti Common Stock, a combination of cash and shares of New Senti Common Stock as determined by the plan administrator, or in any other form of consideration set forth in the restricted stock unit award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by a restricted stock unit award. Except as otherwise provided in the applicable award agreement or by the plan administrator, restricted stock unit awards that have not vested will be forfeited once the participant’s continuous service ends for any reason.

Restricted Stock Awards. Restricted stock awards are granted under restricted stock award agreements adopted by the plan administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, services to us, or any other form of legal consideration that may be acceptable to the plan administrator and permissible under applicable law. The plan administrator determines the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with New Senti ends for any reason, New Senti may receive any or all of the shares of New Senti Common Stock held by the participant that have not vested as of the date the participant terminates service with New Senti through a forfeiture condition or a repurchase right.

Stock Appreciation Rights. Stock appreciation rights are granted under stock appreciation right agreements adopted by the plan administrator. The plan administrator determines the strike price for a stock appreciation right, which generally cannot be less than 100% of the fair market value of New Senti Common Stock on the date of grant. A stock appreciation right granted under the Incentive Plan vests at the rate specified in the stock appreciation right agreement as determined by the plan administrator. Stock appreciation rights may be settled in cash or shares of New Senti Common Stock or in any other form of payment, as determined by the plan administrator and specified in the stock appreciation right agreement.

The plan administrator determines the term of stock appreciation rights granted under the Incentive Plan, up to a maximum of 10 years. Unless the terms of a participant’s stock appreciation rights agreement provide otherwise or as otherwise provided by the plan administrator, if a participant’s service relationship with New Senti or any of its affiliates ceases for any reason other than cause, disability, or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation of service. This period may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by applicable securities laws. Unless the terms of a participant’s stock appreciation rights agreement provide otherwise or as otherwise provided by the plan administrator, if a participant’s service relationship with New Senti or any of its affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock appreciation rights generally terminate

185

immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards. The Incentive Plan permits the grant of performance awards that may be settled in stock, cash or other property. Performance awards may be structured so that the stock or cash will be issued or paid only following the achievement of certain pre-established performance goals during a designated performance period. Performance awards that are settled in cash or other property are not required to be valued in whole or in part by reference to, or otherwise based on, New Senti Common Stock.

The performance goals may be based on any measure of performance selected by the plan administrator. The performance goals may be based on company-wide performance or performance of one or more business units, divisions, affiliates, or business segments, and may be either absolute or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unless specified otherwise by the plan administrator when the performance award is granted, the plan administrator will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (1) to exclude restructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to GAAP; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of items that are “unusual” in nature or occur “infrequently” as determined under GAAP; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any portion of New Senti’s business which is divested achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect of any change in the outstanding shares of New Senti Common Stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common stockholders other than regular cash dividends; (9) to exclude the effects of stock based compensation and the award of bonuses under New Senti’s bonus plans; (10) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under GAAP; and (11) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under GAAP. In addition, the New Senti Board may establish or provide for other adjustment items in the award agreement at the time the award is granted or in such other document setting forth the performance goals at the time the performance goals are established.

Other Stock Awards. The plan administrator may grant other awards based in whole or in part by reference to New Senti Common Stock. The plan administrator will set the number of shares under the stock award (or cash equivalent) and all other terms and conditions of such awards.

Changes to Capital Structure. In the event there is a specified type of change in the capital structure of New Senti, such as a stock split, reverse stock split, or recapitalization, appropriate adjustments will be made to (1) the class and maximum number of shares reserved for issuance under the Incentive Plan, (2) the class of shares by which the share reserve may increase automatically each year, (3) the class and maximum number of shares that may be issued on the exercise of ISOs and (4) the class and number of shares and exercise price, strike price, or purchase price, if applicable, of all outstanding stock awards.

Corporate Transactions. The following applies to stock awards under the Incentive Plan in the event of a corporate transaction (as defined in the Incentive Plan), unless otherwise provided in a participant’s stock award agreement or other written agreement with New Senti or one of its affiliates or unless otherwise expressly provided by the plan administrator at the time of grant.

In the event of a corporate transaction, any stock awards outstanding under the Incentive Plan may be assumed, continued or substituted for by any surviving or acquiring corporation (or its parent company), and any reacquisition or repurchase rights held by New Senti with respect to the stock award may be assigned to New Senti’s successor (or its parent company). If the surviving or acquiring corporation (or its parent company) does not assume, continue or substitute for such stock awards, then (i) with respect to any such stock awards that are

186

held by participants whose continuous service has not terminated prior to the effective time of the corporate transaction, or current participants, the vesting (and exercisability, if applicable) of such stock awards will be accelerated in full (or, in the case of performance awards with multiple vesting levels depending on the level of performance, vesting will accelerate at 100% of the target level) to a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), and such stock awards will terminate if not exercised (if applicable) at or prior to the effective time of the corporate transaction, and any reacquisition or repurchase rights held by New Senti with respect to such stock awards will lapse (contingent upon the effectiveness of the corporate transaction), and (ii) any such stock awards that are held by persons other than current participants will terminate if not exercised (if applicable) prior to the effective time of the corporate transaction, except that any reacquisition or repurchase rights held by New Senti with respect to such stock awards will not terminate and may continue to be exercised notwithstanding the corporate transaction.

In the event a stock award will terminate if not exercised prior to the effective time of a corporate transaction, the plan administrator may provide, in its sole discretion, that the holder of such stock award may not exercise such stock award but instead will receive a payment equal in value to the excess (if any) of (i) the per share amount payable to holders of New Senti Common Stock in connection with the corporate transaction, over (ii) any per share exercise price payable by such holder, if applicable.

Plan Amendment or Termination. The New Senti Board has the authority to amend, suspend, or terminate the Incentive Plan at any time, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. Certain material amendments also require approval of New Senti’s stockholders. No ISOs may be granted after the tenth anniversary of the date the DYNS board of directors adopts the Incentive Plan. No stock awards may be granted under the Incentive Plan while it is suspended or after it is terminated.

U.S. Federal Income Tax Consequences

The following is a summary of the principal U.S. federal income tax consequences to participants and New Senti with respect to participation in the Incentive Plan, which will not become effective until the Closing Date. No awards will be issued under the Incentive Plan prior to the Closing Date. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current U.S. federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local and other tax consequences of the grant or exercise of an award or the disposition of stock acquired under the Incentive Plan. The Incentive Plan is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended. New Senti’s ability to realize the benefit of any tax deductions described below depends on New Senti’s generation of taxable income as well as the requirement of reasonableness and the satisfaction of New Senti’s tax reporting obligations.

Nonstatutory Stock Options. Generally, there is no taxation upon the grant of a NSO. Upon exercise, a participant will recognize ordinary income equal to the excess, if any, of the fair market value of the underlying stock on the date of exercise of the stock option over the exercise price. If the participant is employed by New Senti or one of its affiliates, that income will be subject to withholding taxes. The participant’s tax basis in those shares will be equal to their fair market value on the date of exercise of the stock option, and the participant’s capital gain holding period for those shares will begin on the day after they are transferred to the participant. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant.

Incentive Stock Options. The Incentive Plan provides for the grant of stock options that are intended to qualify as “incentive stock options,” as defined in Section 422 of the Code. Under the Code, a participant

187

generally is not subject to ordinary income tax upon the grant or exercise of an ISO. If the participant holds a share received upon exercise of an ISO for more than two years from the date the stock option was granted and more than one year from the date the stock option was exercised, which is referred to as the required holding period, the difference, if any, between the amount realized on a sale or other taxable disposition of that share and the participant’s tax basis in that share will be long-term capital gain or loss. If, however, a participant disposes of a share acquired upon exercise of an ISO before the end of the required holding period, which is referred to as a disqualifying disposition, the participant generally will recognize ordinary income in the year of the disqualifying disposition equal to the excess, if any, of the fair market value of the share on the date of exercise of the stock option over the exercise price. However, if the sales proceeds are less than the fair market value of the share on the date of exercise of the stock option, the amount of ordinary income recognized by the participant will not exceed the gain, if any, realized on the sale. If the amount realized on a disqualifying disposition exceeds the fair market value of the share on the date of exercise of the stock option, that excess will be short-term or long-term capital gain, depending on whether the holding period for the share exceeds one year. For purposes of the alternative minimum tax, the amount by which the fair market value of a share of stock acquired upon exercise of an ISO exceeds the exercise price of the stock option generally will be an adjustment included in the participant’s alternative minimum taxable income for the year in which the stock option is exercised. If, however, there is a disqualifying disposition of the share in the year in which the stock option is exercised, there will be no adjustment for alternative minimum tax purposes with respect to that share. In computing alternative minimum taxable income, the tax basis of a share acquired upon exercise of an ISO is increased by the amount of the adjustment taken into account with respect to that share for alternative minimum tax purposes in the year the stock option is exercised. New Senti is not allowed a tax deduction with respect to the grant or exercise of an ISO or the disposition of a share acquired upon exercise of an ISO after the required holding period. If there is a disqualifying disposition of a share, however, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant, subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and provided that either the employee includes that amount in income or New Senti timely satisfies its reporting requirements with respect to that amount.

Restricted Stock Awards. Generally, the recipient of a restricted stock award will recognize ordinary income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. If, however, the stock is subject to restrictions constituting a substantial risk of forfeiture when it is received (for example, if the employee is required to work for a period of time in order to have the right to transfer or sell the stock), the recipient generally will not recognize income until the restrictions constituting a substantial risk of forfeiture lapse, at which time the recipient will recognize ordinary income equal to the excess, if any, of the fair market value of the stock on the date it becomes vested over any amount paid by the recipient in exchange for the stock. A recipient may, however, file an election with the IRS, within 30 days following the date of grant, to recognize ordinary income, as of the date of grant, equal to the excess, if any, of the fair market value of the stock on the date the award is granted over any amount paid by the recipient for the stock. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock award will be the amount paid for such shares plus any ordinary income recognized either when the stock is received or when the restrictions constituting a substantial risk of forfeiture lapse. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the restricted stock award.

Restricted Stock Unit Awards. Generally, the recipient of a restricted stock unit award will generally recognize ordinary income at the time the stock is delivered equal to the excess, if any, of (i) the fair market value of the stock received over any amount paid by the recipient in exchange for the stock or (ii) the amount of cash paid to the participant. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock unit award will be the amount paid for such shares plus any ordinary income recognized when the stock is delivered, and the participant’s capital gain holding period for those shares will begin on the day after they are transferred to the participant. Subject to the requirement of

188

reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the restricted stock unit award.

Stock Appreciation Rights. Generally, the recipient of a stock appreciation right will recognize ordinary income equal to the fair market value of the stock or cash received upon exercise. Subject to the requirement of reasonableness, the deduction limits under Section 162(m) of the Code and the satisfaction of a tax reporting obligation, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the recipient of the stock appreciation right.

Tax Consequences to New Senti

Compensation of Covered Employees. The ability of New Senti to obtain a deduction for amounts paid under the Incentive Plan could be limited by Section 162(m) of the Code. Section 162(m) of the Code limits New Senti’s ability to deduct compensation, for U.S. federal income tax purposes, paid during any year to a “covered employee” (within the meaning of Section 162(m) of the Code) in excess of $1.0 million.

Golden Parachute Payments. The ability of New Senti (or the ability of one of its subsidiaries) to obtain a deduction for future payments under the Incentive Plan could also be limited by the golden parachute rules of Section 280G of the Code, which prevent the deductibility of certain “excess parachute payments” made in connection with a change in control of an employer-corporation.

New Plan Benefits

No awards have been previously granted under the Incentive Plan and no awards have been granted that are contingent on stockholder approval of the Incentive Plan. The awards that are to be granted to any participant or group of participants are indeterminable at the date of this proxy statement/prospectus because participation and the types of awards that may be granted under the Incentive Plan are subject to the discretion of the plan administrator. Consequently, no new plan benefits table is included in this proxy statement/prospectus.

Interests of DYNS’s Directors and Officers in the Incentive Plan Proposal

When you consider the recommendation of the DYNS board of directors in favor of approval of the Incentive Plan, you should keep in mind that certain of DYNS’s board of directors and officers have interests in the Incentive Plan that are different from, or in addition to, your interests as a stockholder because they may in the future receive awards under the Incentive Plan. See the section titled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination”.

Vote Required for Approval

The approval of the Incentive Plan Proposal requires the affirmative vote of the holders of a majority of the shares of DYNS Common Stock cast in respect of the relevant Proposal and entitled to vote thereon at the Special Meeting, voting together as a single class.

PROPOSAL 7: THE ESPP PROPOSAL

Overview

In this ESPP Proposal, DYNS is asking its stockholders to approve the ESPP. The DYNS board of directors will adopt the ESPP prior to the Special Meeting, in substantially the form of Annex D attached hereto, subject to stockholder approval at the Special Meeting. If stockholders approve this proposal, the ESPP will become effective on the consummation of the Business Combination. If the ESPP is not approved by the stockholders, it will not become effective. The ESPP is described in more detail below.

The purpose of the ESPP is to provide a means whereby New Senti can align the long-term financial interests of its employees with the financial interests of its stockholders. In addition, the board of directors believes that the ability to allow its employees to purchase shares of New Senti Common Stock will help New Senti to attract, retain, and motivate employees and encourages them to devote their best efforts to New Senti’s business and financial success. Approval of the ESPP by DYNS stockholders will allow New Senti to provide its employees with the opportunity to acquire an ownership interest in New Senti through their participation in the ESPP, thereby encouraging them to remain in service and more closely aligning their interests with those of New Senti’s stockholders. When the Business Combination closes, New Senti is expected to have approximately ninety-three employees eligible to participate in the ESPP.

Description of the ESPP

The material features of the ESPP are described below. The following description of the ESPP is a summary only. This summary is not a complete statement of the ESPP and is qualified in its entirety by reference to the complete text of the ESPP, a copy of which is attached hereto as Annex D. DYNS stockholders should refer to the ESPP for more complete and detailed information about the terms and conditions of the ESPP.

Purpose. The purpose of the ESPP is to provide a means by which eligible employees of New Senti and certain designated companies may be given an opportunity to purchase shares of New Senti Common Stock following the closing of the Business Combination, to assist New Senti in retaining the services of eligible employees, to secure and retain the services of new employees and to provide incentives for such persons to exert maximum efforts for New Senti’s success.

Share Reserve. The maximum number of shares of New Senti Common Stock that may be issued under the ESPP will be equal to 592,584 shares of New Senti common stock. Additionally, the number of shares of New Senti Common Stock reserved for issuance under the ESPP will automatically increase on January 1st of each year, beginning on January 1, 2023 and continuing through and including January 1, 2032, by the lesser of 1% of the total number of shares of New Senti Common Stock on December 31st of the preceding calendar year or such lesser number of shares of New Senti Common Stock as determined by the New Senti Board. Shares subject to purchase rights granted under the ESPP that terminate without having been exercised in full will not reduce the number of shares available for issuance under the ESPP. As of May 3, 2022, the Record Date, the closing price of Class A Common Stock as reported on the Nasdaq was $9.94 per share.

Administration. New Senti’s board of directors, or a duly authorized committee thereof, will administer the ESPP.

Limitations. New Senti employees and the employees of any of its designated affiliates, will be eligible to participate in the ESPP, provided they may have to satisfy one or more of the following service requirements before participating in the ESPP, as determined by the administrator: (1) customary employment with New Senti or one of its affiliates for more than 20 hours per week and five or more months per calendar year or (2) continuous employment with New Senti or one of its affiliates for a minimum period of time, not to exceed two years, prior to the first date of an offering. In addition, the New Senti Board may also exclude from participation in the ESPP or any offering, employees who are “highly compensated employees” (within the meaning of Section 423(b)(4)(D) of

191

the Code) or a subset of such highly compensated employees. If this proposal is approved by the stockholders, all the employees of New Senti and its designated related corporations will be eligible to participate in the ESPP following the closing of the Business Combination. An employee may not be granted rights to purchase stock under the ESPP (a) if such employee immediately after the grant would own stock possessing 5% or more of the total combined voting power or value of all classes of New Senti’s capital stock or (b) to the extent that such rights would accrue at a rate that exceeds $25,000 worth of New Senti’s capital stock for each calendar year that the rights remain outstanding.

The ESPP is intended to qualify as an employee stock purchase plan under Section 423 of the Code. The administrator may specify offerings with a duration of not more than 27 months, and may specify one or more shorter purchase periods within each offering. Each offering will have one or more purchase dates on which shares of New Senti common stock will be purchased for the employees who are participating in the offering. The administrator, in its discretion, will determine the terms of offerings under the ESPP. The administrator has the discretion to structure an offering so that if the fair market value of a share of New Senti Common Stock on any purchase date during the offering period is less than or equal to the fair market value of a share of New Senti Common Stock on the first day of the offering period, then that offering will terminate immediately, and the participants in such terminated offering will be automatically enrolled in a new offering that begins immediately after such purchase date.

A participant may not transfer purchase rights under the ESPP other than by will, the laws of descent and distribution, or as otherwise provided under the ESPP.

Payroll Deductions. The ESPP permits participants to purchase shares of New Senti Common Stock through payroll deductions. Unless otherwise determined by the administrator, the purchase price of the shares will be 85% of the lower of the fair market value of New Senti Common Stock on the first day of an offering or on the date of purchase.

Withdrawal. Participants may withdraw from an offering by delivering a withdrawal form to New Senti and terminating their contributions. Such withdrawal may be elected at any time prior to the end of an offering, except as otherwise provided by the plan administrator. Upon such withdrawal, New Senti will distribute to the employee his or her accumulated but unused contributions without interest, and such employee’s right to participate in that offering will terminate. However, an employee’s withdrawal from an offering does not affect such employee’s eligibility to participate in any other offerings under the ESPP.

Termination of Employment. A participant’s rights under any offering under the ESPP will terminate immediately if the participant either (i) is no longer employed by New Senti or any of its parent or subsidiary companies (subject to any post-employment participation period required by law) or (ii) is otherwise no longer eligible to participate. In such event, New Senti will distribute to the participant his or her accumulated but unused contributions, without interest.

Corporate Transactions. In the event of certain specified significant corporate transactions, such as a merger or change in control, a successor corporation may assume, continue, or substitute each outstanding purchase right. If the successor corporation does not assume, continue, or substitute for the outstanding purchase rights, the offering in progress will be shortened and a new purchase date will be set. The participants’ purchase rights will be exercised on the new purchase date and such purchase rights will terminate immediately thereafter.

Amendment and Termination. New Senti’s board of directors has the authority to amend, suspend, or terminate the ESPP, at any time and for any reason, provided certain types of amendments will require the approval of New Senti stockholders. Any benefits privileges, entitlements and obligations under any outstanding purchase rights granted before an amendment, suspension or termination of the ESPP will not be materially impaired by any such amendment, suspension or termination except (i) with the consent of the person to whom such purchase rights were granted, (ii) as necessary to facilitate compliance with any laws, listing requirements,

192

or governmental regulations, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. The ESPP will remain in effect until terminated by New Senti’s board of directors in accordance with the terms of the ESPP.

U.S. Federal Income Tax Consequences

The following is a summary of the principal U.S. federal income tax consequences to participants and New Senti with respect to participation in the ESPP. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current U.S. federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local, and other tax consequences of the grant or exercise of a purchase right or the sale or other disposition of New Senti Common Stock acquired under the ESPP. The ESPP is not qualified under the provisions of Section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Section 423 of the Code

Rights granted under the ESPP are intended to qualify for favorable U.S. federal income tax treatment associated with rights granted under an employee stock purchase plan which qualifies under the provisions of Section 423 of the Code.

A participant will be taxed on amounts withheld for the purchase of shares of New Senti Common Stock as if such amounts were actually received. Otherwise, no income will be taxable to a participant as a result of the granting or exercise of a purchase right until a sale or other disposition of the acquired shares. The taxation upon such sale or other disposition will depend upon the holding period of the acquired shares.

If the shares are sold or otherwise disposed of more than two years after the beginning of the offering period and more than one year after the shares are transferred to the participant, then the lesser of the following will be treated as ordinary income: (i) the excess of the fair market value of the shares at the time of such sale or other disposition over the purchase price; or (ii) the excess of the fair market value of the shares as of the beginning of the offering period over the purchase price (determined as of the beginning of the offering period). Any further gain or any loss will be taxed as a long-term capital gain or loss.

If the shares are sold or otherwise disposed of before the expiration of either of the holding periods described above, then the excess of the fair market value of the shares on the purchase date over the purchase price will be treated as ordinary income at the time of such sale or other disposition. The balance of any gain will be treated as capital gain. Even if the shares are later sold or otherwise disposed of for less than their fair market value on the purchase date, the same amount of ordinary income is attributed to the participant, and a capital loss is recognized equal to the difference between the sales price and the fair market value of the shares on such purchase date. Any capital gain or loss will be short-term or long-term, depending on how long the shares have been held.

New Senti is not allowed a deduction upon the grant or exercise of a purchase right or the disposition of a share acquired upon exercise of a purchase right after the required holding period. If the shares are sold or otherwise disposed of before the expiration of either holding period, New Senti will generally be entitled to a tax deduction equal to the taxable ordinary income, realized by the participant.

New Plan Benefits

Participation in the ESPP is voluntary and each eligible employee will make his or her own decision regarding whether and to what extent to participate in the ESPP. Therefore, DYNS cannot currently determine the benefits or number of shares subject to purchase rights and a new plan benefits table is thus not provided.

When you consider the recommendation of the DYNS board of directors in favor of approval of the ESPP, you should keep in mind that certain of DYNS’s directors and officers have interests in the ESPP that are different from, in addition to, or in conflict with your interests as a stockholder, including, among other things, the existence of financial and personal interests in the event they participate in the ESPP. See the section titled “Summary of the Proxy Statement/Prospectus — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination”.

DYNS’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE ESPP PROPOSAL.

194

PROPOSAL 8: THE ADJOURNMENT PROPOSAL

The Adjournment Proposal allows the Board to submit a proposal to adjourn the Special Meeting to a later date or dates if DYNS is unable to consummate the Business Combination for any reason. In no event will DYNS solicit proxies to adjourn the Special Meeting or consummate the Business Combination beyond the date by which it may properly do so under the Business Combination Agreement or its Current Charter and Delaware law. The purpose of the Adjournment Proposal is to provide more time to consummate the Business Combination, if necessary and appropriate. See the section entitled “Proposal 1: The Business Combination Proposal — Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination.”

In addition to an adjournment of the Special Meeting upon approval of the Adjournment Proposal, the Board is empowered under Delaware law to postpone the Special Meeting at any time prior to the meeting being called to order. In such event, DYNS will issue a press release and take such other steps as it believes are necessary and practical in the circumstances to inform its stockholders of the postponement.

Consequences if the Adjournment Proposal is not Approved

If the Adjournment Proposal is presented at the Special Meeting and is not approved by DYNS’s stockholders, the Board may not be able to adjourn the Special Meeting to a later date if DYNS is unable to consummate the Business Combination (because either the Business Combination Proposal is not approved or the conditions to consummating the Business Combination have not been met). In such event, the Business Combination would not be completed.

Required Vote of DYNS Stockholders

Approval of the Adjournment Proposal requires the affirmative vote of a majority of the issued and outstanding shares of DYNS Common Stock cast by the stockholders represented in person (which would include presence at a virtual meeting) or by proxy at the Special Meeting and entitled to vote thereon. Presentation of the Adjournment Proposal at the Special Meeting is not conditioned upon the approval of any of the other Proposals.

Recommendation of the Board

Financial Position

We have funds available for an initial business combination of approximately $230,000,000, after our expected payment of a maximum of $7,050,000 of deferred underwriting fees, before fees and expenses associated with our initial business combination (other than deferred underwriting fees) and before any redemptions by holders of Public Shares. We have also undertaken steps to secure third-party equity financing in an aggregate amount of $66.8 million via the PIPE Investment.

Effecting Our Initial Business Combination

Selection of a Target Business and Structuring of our Initial Business Combination

Nasdaq rules require that we must complete one or more business combinations having an aggregate fair market value of at least 80% of the value of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of our signing a definitive agreement in connection with our initial business combination. The Board determined that this test was met in connection with the proposed Business Combination.

Redemption Rights for Public Stockholders upon Completion of our Initial Business Combination

We are providing our Public Stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial business combination, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, divided by the number of then outstanding Public Shares, subject to the

199

limitations described herein. The amount in the Trust Account was approximately $10.00 per share as of the Record Date. The per-share amount we will distribute to holders of Public Shares who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the underwriters of our Initial Public Offering. The Sponsor and our officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to their Founder Shares, Private Placement Shares and Public Shares held by them in connection with the completion of our initial business combination.

Limitation on Redemption Right

Notwithstanding the foregoing, in no event will we redeem our Public Shares in an amount that would cause our net tangible assets to be less than $5,000,001.

Redemption of Public Shares and Liquidation if no Initial Business Combination

We have until May 28, 2023 to complete our initial business combination. If we are unable to complete our initial business combination by such date, we will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor and our officers and directors have entered into a letter agreement with us, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to any Founder Shares and Private Placement Shares held by them if we fail to complete our initial business combination by May 28, 2023. However, if the Sponsor, or our officers or directors acquired Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if we fail to complete our initial business combination within 24 months from the closing of the Initial Public Offering.

The Sponsor and our officers and directors have agreed, pursuant to a written agreement with us, that they will not propose any amendment to our Current Charter (i) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our Public Shares if we do not complete our initial business combination by May 28, 2023 or (ii) with respect to any material provision relating to the rights of Public Stockholders, unless we provide our Public Stockholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, divided by the number of then outstanding Public Shares. However, we may not redeem our Public Shares unless our net tangible assets are at least $5,000,001, either immediately prior to or upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules). If this optional redemption right is exercised with respect to an excessive number of Public Shares such that we cannot satisfy the net tangible asset requirement (described above), we would not proceed with the amendment or the related redemption of our Public Shares at such time.

We expect that all costs and expenses associated with implementing our plan of dissolution (if required), as well as payments to any creditors, will be funded from amounts remaining out of the approximately $889,323 of

200

proceeds held outside the Trust Account (as at December 31, 2021), although we cannot provide any assurance that there will be sufficient funds for such purpose. We will depend on sufficient interest being earned on the proceeds held in the Trust Account to pay any tax obligations we may owe. However, if those funds are not sufficient to cover the costs and expenses associated with implementing our plan of dissolution, to the extent that there is any interest accrued in the Trust Account not required to pay taxes, we may request the trustee of the Trust Account (Continental) to release to us an additional amount of up to, as of the Record Date, $89,497.46 of such accrued interest to pay those costs and expenses.

If we were to expend all of the net proceeds of the Initial Public Offering and the Concurrent Private Placement, other than the proceeds deposited in the Trust Account, and without taking into account interest, if any, earned on the Trust Account, the per-share redemption amount received by stockholders upon our dissolution would be approximately $10.00. The proceeds deposited in the Trust Account could, however, become subject to the claims of our creditors which would have higher priority than the claims of our Public Stockholders. We cannot provide any assurance that the actual per-share redemption amount received by stockholders will not be substantially less than $10.00. Under Section 281(b) of the DGCL, our plan of dissolution must provide for all claims against us to be paid in full or make provision for payments to be made in full, as applicable, if there are sufficient assets. These claims must be paid or provided for before we make any distribution of our remaining assets to our stockholders. While we intend to pay such amounts, if any, we cannot provide any assurance that we will have funds sufficient to pay or provide for all creditors’ claims.

Although we seek to have all vendors, service providers, prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of our Public Stockholders, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the Trust Account including but not limited to fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against our assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Examples of possible instances where we may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. Marcum LLP, our independent registered public accounting firm, has not executed agreements with us waiving such claims to the monies held in the Trust Account.

In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the Trust Account for any reason. Pursuant to a letter agreement, the Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act.

However, we have not asked the Sponsor to reserve for such indemnification obligations, nor have we

201

independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of our company. Therefore, we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the Trust Account are reduced below (i) $10.00 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes, and the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against the Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors, in exercising their business judgment, may choose not to do so if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. We have not asked the Sponsor to reserve for such indemnification obligations and we cannot provide any assurance that the Sponsor would be able to satisfy those obligations. Accordingly, we cannot provide any assurance that due to claims of creditors the actual value of the per-share redemption price will not be less than $10.00 per Public Share.

We will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than our independent registered public accounting firm), prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. The Sponsor will also not be liable as to any claims under our indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act. As at December 31, 2021, we had access to up to approximately $889,323 from the proceeds of the Initial Public Offering and the Concurrent Private Placement with which to pay any such potential claims (including costs and expenses incurred in connection with our liquidation, currently estimated to be no more than approximately $100,000). In the event that we liquidate and it is subsequently determined that the reserve for claims and liabilities is insufficient, stockholders who received funds from our Trust Account could be liable for claims made by creditors.

Under the DGCL, stockholders may be held liable for claims by third parties against a corporation to the extent of distributions received by them in a dissolution. The pro rata portion of our Trust Account distributed to our Public Stockholders upon the redemption of our Public Shares in the event we do not complete our initial business combination by May 28, 2023 (or any stockholder-approved extension period) may be considered a liquidating distribution under Delaware law. If the corporation complies with certain procedures set forth in Section 280 of the DGCL intended to ensure that it makes reasonable provision for all claims against it, including a 60-day notice period during which any third-party claims can be brought against the corporation, a 90-day period during which the corporation may reject any claims brought, and an additional 150-day waiting period before any liquidating distributions are made to stockholders, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would be barred after the third anniversary of the dissolution.

Furthermore, if the pro rata portion of our Trust Account distributed to our Public Stockholders upon the redemption of our Public Shares in the event we do not complete our initial business combination by May 28, 2023 (or any stockholder-approved extension period), is not considered a liquidating distribution under Delaware law and such redemption distribution is deemed to be unlawful (potentially due to the imposition of legal proceedings that a party may bring or due to other circumstances that are currently unknown), then pursuant to Section 174 of the DGCL, the statute of limitations for claims of creditors could then be six years after the unlawful redemption distribution, instead of three years, as in the case of a liquidating distribution. If we are

202

unable to complete our initial business combination by May 28, 2023 (or any stockholder-approved extension period), we will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and the Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) above to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Accordingly, where applicable, it is our intention to redeem our Public Shares as soon as reasonably possible following our 24^th month and, therefore, we do not intend to comply with those procedures. As such, our stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of our stockholders may extend well beyond the third anniversary of such date.

Because we will not be complying with Section 280 of the DGCL, Section 281(b) of the DGCL requires us to adopt a plan, based on facts known to us at such time that will provide for our payment of all existing and pending claims or claims that may be potentially brought against us within the subsequent ten years. However, because we are a blank check company, rather than an operating company, and our operations will be limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from our vendors (such as lawyers, investment bankers, etc.) or prospective target businesses. As described above, pursuant to the obligation contained in our underwriting agreement, we will seek to have all vendors, service providers (other than our independent registered public accounting firm), prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account. As a result of this obligation, the claims that could be made against us are significantly limited and the likelihood that any claim that would result in any liability extending to the Trust Account is remote. Further, the Sponsor may be liable only to the extent necessary to ensure that the amounts in the Trust Account are not reduced below (i) $10.00 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, due to reductions in value of the trust assets, in each case net of the amount of interest withdrawn to pay taxes and will not be liable as to any claims under our indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act. In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims.

If we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our Public Stockholders. To the extent any bankruptcy claims deplete the Trust Account, we cannot provide any assurance that we will be able to return $10.00 per share to our Public Stockholders. Additionally, if we file a bankruptcy petition or an involuntary bankruptcy petition is filed against us that is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by our stockholders. Furthermore, our Board may be viewed as having breached its fiduciary duty to our creditors and/or may have acted in bad faith, thereby exposing itself and our company to claims of punitive damages, by paying Public Stockholders from the Trust Account prior to addressing the claims of creditors. We cannot provide any assurance that claims will not be brought against us for these reasons.

Competition

If we succeed in effecting the Business Combination with Senti, we may compete with a number of companies that have preclinical and early clinical-stage research programs underway to develop products that

203

could potentially compete with Senti’s. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are more effective, safer, have fewer or less severe side effects, are more convenient or are less expensive than the products that we may develop. We cannot assure you that, subsequent to the Business Combination, we will have the resources to compete effectively.

Facilities

Our executive offices are currently located at 2875 El Camino Real, Redwood City, CA 94061 and our telephone number is (408) 212-0200. Our executive offices are provided to us by the Sponsor. We consider our current office space adequate for our current operations.

Employees

We currently have four executive officers. These individuals are not obligated to devote any specific number of hours to our matters but they intend to devote as much of their time as they deem necessary to our affairs until we have completed our initial business combination. The amount of time they will devote in any time period will vary based on whether a target business has been selected for our initial business combination and the stage of the initial business combination process we are in. We do not intend to have any other full- or part-time employees prior to the completion of our initial business combination.

Periodic Reporting and Financial Information

We have registered our Class A Common Stock under the Exchange Act and have reporting obligations, including the requirement that we file annual, quarterly and current reports with the SEC. In accordance with the requirements of the Exchange Act, we filed our annual report for the fiscal year ended December 31, 2021 with the SEC on March 7, 2022. This annual report contains financial statements audited and reported on by our independent registered public accountants.

We evaluated our internal control procedures for the fiscal year ending December 31, 2021, as required by the Sarbanes-Oxley Act. Only in the event we are deemed to be a large accelerated filer or an accelerated filer, and no longer qualify as an emerging growth company, will we be required to have an auditor attest to our internal control procedures. A target company may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of their internal controls. The development of the internal controls of any such entity to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete any such business combination. We have filed a Registration Statement on Form 8-A with the SEC to voluntarily register our Class A Common Stock under Section 12 of the Exchange Act. As a result, we are subject to the rules and regulations promulgated under the Exchange Act. We have no current intention of filing a Form 15 to suspend our reporting or other obligations under the Exchange Act prior or subsequent to the consummation of our initial business combination.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying

204

with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We intend to take advantage of the benefits of this extended transition period.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of the Initial Public Offering, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our shares of Class A Common Stock that are held by non-affiliates exceeds $700 million as of the prior June 30^th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. References herein to “emerging growth company” will have the meaning associated with it in the JOBS Act.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company if (1) the market value of our common stock held by non-affiliates is less than $250 million as of the last business day of the second fiscal quarter, or (2) our annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter are less than $100 million and the market value of our common stock held by non-affiliates is less than $700 million as of the last business day of the second fiscal quarter.

Legal Proceedings

There is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team in their capacity as such, and we and the members of our management team have not been subject to any such proceeding in the twelve months preceding the date of this proxy statement/prospectus.

Overview

We are a blank check company incorporated on March 1, 2021 as a Delaware corporation and formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. We intend to effectuate our initial business combination (the Business Combination) using cash from the proceeds of our Initial Public Offering and Concurrent Private Placement, the proceeds of the sale of our shares in connection with our initial business combination (the PIPE Investment), and shares issued to the current owners of Senti.

On May 28, 2021, we consummated our Initial Public Offering of 23,000,000 shares of Class A Common Stock, including 3,000,000 shares that were issued pursuant to the underwriter’s exercise of its over-allotment option in full. The shares of Class A Common Stock were sold at a price of $10.00 per share, generating gross proceeds of $230,000,000. J.P. Morgan acted as the sole book running manager of the Initial Public Offering. The securities sold in the Initial Public Offering were registered under the Securities Act on a registration statement on Form S-1 (File No. 333-255930). The SEC declared the registration statement effective on May 25, 2021.

On May 28, 2021, simultaneously with the consummation of the Initial Public Offering, we completed the Concurrent Private Placement of an aggregate of 715,500 shares of Class A Common Stock (the Private Placement Shares) to the Sponsor at a purchase price of $10.00 per Private Placement Share, generating gross proceeds to us of $7,155,000. Such securities were issued pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

A total of $230,000,000, comprised of $225,400,000 of the net proceeds from the Initial Public Offering (which amount included $8,050,000 of the underwriter’s deferred discount (prior to such amount being reduced by $1,000,000 to $7,050,000 by written agreement with J.P. Morgan on December 17, 2021)) and $4,600,000, representing part of the proceeds of the sale of the Private Placement Shares, was placed in a U.S.-based Trust Account maintained by Continental, acting as trustee.

206

The issuance of additional shares in connection with the Business Combination to the current owners of Senti and the PIPE Investors:

•

may significantly dilute the equity interest of DYNS stockholders;

•

could cause a change in control if a substantial number of shares of our common stock is issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any;

•

may have the effect of delaying or preventing a change of control of us by diluting the stock ownership or voting rights of a person seeking to obtain control of us; and

•

may adversely affect prevailing market prices for our Class A Common Stock.

Similarly, and although we do not currently intend to do so, if we issue debt securities or otherwise incur significant debt to bank or other lenders, it could result in:

•

default and foreclosure on our assets if our operating revenues after the Business Combination are insufficient to repay our debt obligations;

•

acceleration of our obligations to repay the indebtedness even if we make all principal and interest payments when due if we breach certain covenants that require the maintenance of certain financial ratios or reserves without a waiver or renegotiation of that covenant;

•

our immediate payment of all principal and accrued interest, if any, if the debt is payable on demand;

•

our inability to obtain necessary additional financing if the debt contains covenants restricting our ability to obtain such financing while the debt is outstanding;

•

our inability to pay dividends on our common stock;

•

using a substantial portion of our cash flow to pay principal and interest on our debt, which will reduce the funds available for dividends on our common stock if declared, our ability to pay expenses, make capital expenditures and acquisitions, and fund other general corporate purposes;

•

limitations on our flexibility in planning for and reacting to changes in our business and in the industry in which we operate;

•

increased vulnerability to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;

•

limitations on our ability to borrow additional amounts for expenses, capital expenditures, acquisitions, debt service requirements, and execution of our strategy; and

•

other purposes and other disadvantages compared to our competitors who have less debt.

As indicated in the accompanying financial statements, as of December 31, 2021, we had $889,323 in cash (excluding funds held in the Trust Account). Further, we expect to incur significant costs in the pursuit of the Business Combination. We cannot assure you that our plans to raise capital or to complete the Business Combination will be successful.

Results of Operations and Known Trends or Future Events

We have neither engaged in any operations nor generated any revenues to date. Our only activities for the period from March 1, 2021 (inception) through December 31, 2021 were organizational activities, those necessary to prepare for our Initial Public Offering, described below, and, after the Initial Public Offering, identifying target companies for a business combination, conducting due diligence on such target companies and negotiating the Business Combination Agreement with Senti, which will give effect to our initial business combination. We do not expect to generate any operating revenues until after completion of our initial business combination. We generate non-operating income in the form of interest income on cash and cash equivalents

207

held in the Trust Account following our Initial Public Offering. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), and we incurred expenses for due diligence in connection with identifying Senti as a target company for our initial business combination.

For the period from March 1, 2021 (inception) through December 31, 2021, we had a net loss of $3,857,088, which resulted from operating and formation costs of $3,702,033 and franchise tax expense of $163,839 partially offset by interest and dividend income on investments in the Trust Account of $8,784.

Liquidity and Capital Resources

On May 28, 2021, we consummated the Initial Public Offering of 23,000,000 Public Shares, including 3,000,000 Public Shares that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at $10.00 per Public Share, generating gross proceeds of $230,000,000.

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 715,500 shares of Class A Common Stock at a price of $10.00 per share (the Private Placement Shares), generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares has been added to the net proceeds from the Initial Public Offering held in the Trust Account. If we do not complete our initial business combination within 24 months of the closing of the Initial Public Offering, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

For the period from March 1, 2021 (inception) through December 31, 2021, net cash used in operating activities was $1,142,247, which was due to our net loss of $3,857,088, and non-cash interest and dividend income on investments held in the Trust Account, partially offset by changes in working capital of $2,723,625.

For the period from March 1, 2021 (inception) through December 31, 2021, net cash used in investing activities of $230,000,000 was the result of the amount of net proceeds from the Initial Public Offering and the private placement sale of shares being deposited to the Trust Account.

Net cash provided by financing activities for the period from March 1, 2021 (inception) through December 31, 2021 of $232,031,570 was comprised of $225,400,000 in proceeds from the issuance of shares in the Initial Public Offering, net of underwriter’s discount paid, $7,155,000 in proceeds from the issuance of shares in a private placement to our Sponsor, and proceeds from the issuance of a promissory note to our sponsor of $250,000, offset by the payment of $523,430 for offering costs associated with the Initial Public Offering and repayment of the outstanding balance on the promissory note to our Sponsor of $250,000.

As of December 31, 2021, we had cash of $889,323 held outside the Trust Account. We intend to use the funds held outside the Trust Account primarily to complete the Business Combination with Senti.

We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less taxes payable and deferred underwriting commissions), to complete our initial business combination. We may withdraw interest income (if any) to pay income taxes, if any. Our annual income tax obligations will depend on the amount of interest and other income earned on the amounts held in the Trust Account. We expect the interest income earned on the amount in the Trust Account (if any) will be sufficient to pay our income taxes. To the extent that our equity or debt is used, in whole or in part, as consideration to complete our initial business combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

We do not believe we will need to raise additional funds in order to meet the expenditures required for operating our business up to (and including) the Closing. However, if our estimates are less than the actual

208

amount necessary to do so, we may have insufficient funds available. In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination, our Sponsor or an affiliate of our Sponsor, or certain of our officers or directors may, but are not obligated to, loan us funds as may be required. If we complete our initial business combination, we would repay such loaned amounts. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts, but no proceeds from our Trust Account would be used for such repayment. Up to $2,000,000 of such loans may be convertible into shares of the post-business combination entity at a price of $10.00 per share at the option of the lender. The shares would be identical to the Private Placement Shares. The terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans. We do not expect to seek loans (if required) from parties other than our Sponsor or an affiliate of our Sponsor, or certain of our officers or directors as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our Trust Account.

Related Party Transactions

Founder Shares

On March 8, 2021, we issued 5,750,000 shares of Class B Common Stock (the Founder Shares) to our Sponsor for an aggregate price of $25,000. These Founder Shares included an aggregate of up to 750,000 shares of Class B Common Stock subject to forfeiture by our Sponsor to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that our Sponsor would own, on an as-converted basis, 20% of our issued and outstanding shares after our Initial Public Offering (excluding the Private Placement Shares and assuming our Sponsor did not purchase any Public Shares in our Initial Public Offering). The underwriter fully exercised the over-allotment option on May 28, 2021; thus, these 750,000 Founder Shares are no longer subject to forfeiture.

Private Placement

Simultaneously with the closing of our Initial Public Offering, we consummated the sale of 715,500 shares of Class A Common Stock (the Private Placement Shares) at a price of $10.00 per share in a private placement to our Sponsor, generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares was added to the net proceeds from our Initial Public Offering held in the Trust Account. If we do not complete an initial business combination within 24 months from the closing of our Initial Public Offering, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of Public Shares (subject to the requirements of applicable law).

Promissory Note — Related Party

On March 8, 2021, we issued an unsecured promissory note to our Sponsor (the “Promissory Note”), pursuant to which we could borrow up to an aggregate of $300,000 to cover expenses related to our Initial Public Offering. The Promissory Note was non-interest bearing and was payable on the earlier of December 31, 2021 or the consummation of our Initial Public Offering. In April 2021, the Company borrowed $250,000 under the Promissory Note, which was repaid on May 26, 2021.

Administrative Support Agreement

We entered into an agreement, commencing on the effective date of our Initial Public Offering, to pay our Sponsor up to a total of $10,000 per month for office space, administrative and support services. Upon the completion of an initial business combination, the agreement will terminate. To date, we have not exercised our option to use such services and have not paid any fees to our Sponsor.

209

Related Party Loans

In addition, in order to finance transactions costs in connection with a business combination, the Sponsor, or certain of the Company’s officers, directors, or their affiliates may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a business combination, the Company will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a business combination is not completed, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such Working Capital Loans may be converted into shares at a price of $10.00 per share at the option of the lender. The share would be identical to the Private Placement Shares.

Sponsor Support Agreement

In connection with the execution of the Business Combination Agreement, the Sponsor and each of our officers and directors entered into the Sponsor Support Agreement with DYNS and Senti. Under the Sponsor Support Agreement, the Sponsor has agreed to vote, at any meeting of the stockholders of DYNS and in any action by written consent of the stockholders of DYNS, all of its shares of Class B Common Stock (together with any other equity securities of DYNS that it holds of record or beneficially, as of the date of the Sponsor Support Agreement, or of which it acquires record or beneficial ownership after the date thereof (the “Subject DYNS Equity Securities”) (i) in favor of (a) the Business Combination Agreement and the transactions contemplated thereby and (b) the other proposals that DYNS and Senti agreed in the Business Combination Agreement shall be submitted at such meeting for approval by DYNS’s stockholders together with the proposal to obtain the DYNS stockholders’ approval for the Business Combination (the “Required Transaction Proposals”) and (ii) against any proposal that conflicts or materially impedes or interferes with any Required Transaction Proposals or that would adversely affect or delay the Business Combination. The Sponsor Support Agreement also prohibits the Sponsor from, among other things and subject to certain exceptions, selling, assigning or transferring any Subject DYNS Equity Securities held by the Sponsor or taking any action that would have the effect of preventing or materially delaying the Sponsor from performing its obligations under the Sponsor Support Agreement. In addition, in the Sponsor Support Agreement, the Sponsor agrees to waive, and not to assert or perfect, among other things, any rights to adjustment or other anti-dilution protections with respect to the rate at which the shares of Class B Common Stock held by the Sponsor convert into shares of Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement.

Commitments and Contingencies

Registration Rights

The holders of the Founder Shares and Private Placement Shares will be entitled to registration rights pursuant to the registration and stockholder rights agreement requiring us to register such securities for resale (in the case of the Founder Shares, only after conversion to our Class A Common Stock). As at the date of this proxy statement/prospectus, there are 5,750,000 Founder Shares and 715,500 Private Placement Shares outstanding, however, pursuant to the Non-Redemption Agreements, if the Business Combination is consummated, the Sponsor anticipates that it will forfeit 885,377 Founder Shares, leaving it with 4,864,623 Founder Shares immediately after Closing. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of an initial business combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. The registration and stockholder rights agreement does not contain liquidated damages or other cash settlement provisions resulting from delays in registering our securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

210

If the Sponsor forfeits 885,377 Founder Shares, as described in the paragraph above, then, pursuant to the Non-Redemption Agreements, an aggregate of 885,377 shares of Class A Common Stock (which will be New Senti Common Stock) will be issued to the Anchor Investors. Under the Investor Rights Agreement, the Anchor Investors will be entitled to registration rights in respect of these shares.

In addition, the PIPE Investors will be entitled to registration rights pursuant to the Subscription Agreements they have entered into with DYNS in connection with the PIPE Investment. The PIPE Investors will subscribe for, in aggregate, 6,680,000 shares of Class A Common Stock concurrently with the consummation of the Business Combination, and all such shares will have registration rights.

In total, after the consummation of the Business Combination, an aggregate of 13,145,500 shares of New Senti Common Stock will be subject to registration rights, comprising 715,500 Private Placement Shares, 4,864,623 Founder Shares, 885,377 shares of Class A Common Stock issuable to Anchor Investors and 6,680,000 shares of Class A Common Stock issuable to PIPE Investors.

Underwriting Agreement

In connection with our Initial Public Offering, the Company granted the underwriter a 45-day option to purchase up to 3,000,000 additional shares of Class A Common Stock to cover over-allotments at the Initial Public Offering price, less the underwriting discounts and fees. The underwriter exercised its over-allotment option in full on May 28, 2021.

The underwriter was paid a cash underwriting fee of $0.20 per share, or $4,600,000 in the aggregate, upon the closing of our Initial Public Offering. In addition, approximately $0.306 per share, or $7,050,000 in the aggregate, may be payable to the underwriter for deferred underwriting fees (this amount having being reduced from $8,050,000 by $1,000,000 by agreement with the underwriter on December 17, 2021). The deferred underwriting fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that the Company completes its initial business combination, subject to the terms of the underwriting agreement. The deferred underwriting fee of $7,050,000 payable to the underwriter (J.P. Morgan) if the Business Combination is consummated may create a conflict of interest for J.P. Morgan in its capacity as capital markets advisor in connection with the Business Combination.

Financial Advisor Agreement

On December 16, 2021, DYNS entered into an agreement (the “Financial Advisor Agreement”) with Morgan Stanley for financial advisory services in connection with the Business Combination, which services Morgan Stanley had been engaged to provide, and which services Morgan Stanley had provided, since August 4, 2021. The Financial Advisor Agreement shall terminate automatically on December 16, 2022 unless terminated earlier, with or without cause, by either DYNS or Morgan Stanley. DYNS will pay Morgan Stanley a fee of $1,000,000 upon the consummation of our proposed initial business combination with Senti.

Placement Agent Agreement

On September 21, 2021, DYNS entered into an agreement (the “Placement Agent Agreement”) with Morgan Stanley, J.P. Morgan and BofA Securities (together, the “co-placement agents”) for services in connection with the placement of shares of our Class A Common Stock to the PIPE Investors. The Placement Agent Agreement shall terminate automatically on August 28, 2022 unless terminated earlier, with or without cause, by either DYNS or any co-placement agent (as to itself only). DYNS will pay to the co-placement agents a total fee equal to 4.0% of the aggregate price at which the shares of our Class A Common Stock are sold to the PIPE Investors, which fee shall be payable upon the consummation of the placement of the shares. Each of the co-placement agents will receive 33.3% of the fee.

211

Business Combination Agreement

As described elsewhere in this proxy statement/prospectus, we have entered into the Business Combination Agreement with Merger Sub and Senti pursuant to which, among other things, Merger Sub will merge with and into Senti, with Senti surviving as a wholly-owned subsidiary of DYNS. We have also entered into various ancillary transaction documents to give effect to the Business Combination, which are described throughout this proxy statement/prospectus.

Risks and Uncertainties

Management is continuing to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on our financial position and results of our operations, the specific impact is not readily determinable as of the date of this proxy statement/prospectus. The financial statements set forth in this proxy statement/prospectus do not include any adjustments that might result from the outcome of this uncertainty.

Off-Balance Sheet Arrangements

As of December 31, 2021, we did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual Obligations

Refer to the section entitled “Commitments and Contingencies” above for information regarding DYNS’s obligations under the underwriting agreement, the Financial Advisor Agreement, the Placement Agent Agreement, the Business Combination Agreement and in respect of stockholders’ registration rights.

Critical Accounting Policies

The preparation of condensed financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following critical accounting policies:

Net Loss Per Common Share

Net loss per common share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. As the Public Shares are considered to be redeemable at fair value, and a redemption at fair value does not amount to a distribution different than other stockholders, Class A Common Stock and Class B Common Stock are presented as one class of stock in calculating net loss per share. As a result, the calculated net loss per share is the same for Class A Common Stock and Class B Common Stock. At December 31, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the periods presented.

Class A Common Stock Subject to Possible Redemption

We account for our Class A Common Stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) 480, Distinguishing Liabilities from Equity. Shares of Class A

212

Common Stock subject to mandatory redemption is classified as a liability instrument and measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. Our Class A Common Stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, Class A Common Stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of our condensed balance sheets. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of the redeemable Class A Common Stock subject to possible redemption resulted in charges against additional paid-in capital and accumulated deficit.

Recent Accounting Standards

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company adopted ASU 2020-06 effective January 1, 2021 using the modified retrospective method of transition. The adoption of ASU 2020-06 did not have a material impact on our consolidated financial statements for the fiscal year ended December 31, 2021.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our condensed financial statements.

JOBS Act

The JOBS Act contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We qualify as an “emerging growth company” and under the JOBS Act will be allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal control over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to

213

median employee compensation. These exemptions will apply for a period of five years following the completion of our Initial Public Offering or until we are no longer an “emerging growth company,” whichever is earlier.

Quantitative and Qualitative Disclosures about Market Risk

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

Executive Officers of DYNS

Directors and Executive Officers

As of the date of this proxy statement/prospectus, our directors and officers are as follows:


NAME	AGE		POSITION
Omid Farokhzad		53	Executive Chair; Director
Mostafa Ronaghi		53	Chief Executive Officer; Director
Mark Afrasiabi		46	Chief Financial Officer
Rowan Chapman		51	Chief Business Officer
David Epstein		60	Director
Jay Flatley		69	Director
Deep Nishar		53	Director

Mostafa Ronaghi, Ph.D.—Chief Executive Officer & Director: Dr. Ronaghi is a scientist-entrepreneur, inventor, investor, company-founder, executive and director. Most recently, he was Chief Technology Officer, Senior Vice President and member of the Executive Leadership Team at Illumina, Inc. (Nasdaq: ILMN) from 2008 to 2021. While at Illumina, in 2016, Dr. Ronaghi co-founded GRAIL, a next-gen liquid biopsy platform for cancer detection. He also started Illumina’s Research & Technology Development group, and co-founded the Illumina Accelerator Program in 2014, one of the most successful accelerator programs in the industry, which coached and invested in more than 50 start-ups, achieving one of the highest success rates for securing external institutional funding. Prior to Illumina, Dr. Ronaghi was Principal Investigator at the Stanford Genome Technology Center from 1999 to 2008. Throughout his prolific career, Dr. Ronaghi co-founded several other companies, including Pyrosequencing AB (founded in 1997; IPO in 2000 in Stockholm), which focused on sequencing-by-synthesis technology (which was the first next-gen sequencing technology, and laid the

214

groundwork for the leading technology developed by Illumina). He then co-founded ParAllele Biosciences in 2001, which was acquired by Affymetrix in 2005, which developed a first-of-its-kind technology for highly multiplex genotyping (used by the international Hapmap project to identify genetic variations across different population and diseases). He co-founded NextBio in 2004 (acquired by Illumina in 2013), where he developed a software platform to analyze molecular biological data. He also co-founded Avantome in 2008 (acquired by Illumina in 2008) as a low-cost DNA sequencer to democratize sequencing. He has advised and invested in more than 70 companies and is an inventor on over 30 issued and pending patents, as well as authored more than 80 scientific publications. He is also a recipient of the 2015 Ellis Island Medal of Honor. He currently serves as a Board member at Seer (Nasdaq: SEER), 1Health, Clearlabs, and three other private companies. Dr. Ronaghi holds a Ph.D. in Biotechnology from Royal Institute of Technology in Stockholm, and B.Sc in Biomedical Chemistry from University of Kalmar in Sweden.

215

Diagnostic units. Under his leadership, Norvartis’s oncology business grew to the second largest in the world. Mr. Epstein has more than 25 years of extensive drug development, deal making, commercialization and leadership experience on a global scale. Over the course of his career, he led the development and commercialization of over 30 new molecular entities, including major breakthroughs such as Glivec^®, Tasigna^®, Gilenya^®, Cosentyx^® and Entresto^®. His teams developed three Prix Galien award winners, and he has mentored several CEOs into their roles. In 2015, he was named by FierceBiotech as one of the “25 most influential people in biopharma.” Early in his career, he was an associate in the strategy practice of consulting firm Booz, Allen and Hamilton. Mr. Epstein holds a BS in pharmacy from Rutgers University College of Pharmacy and an MBA in finance and marketing from Columbia University Graduate School of Business.

As noted in our Form S-1 at the time of DYNS’s Initial Public Offering, we believe our Board and management team are well positioned to take advantage of the growing set of investment opportunities focused on the biotechnology sector, and that our contacts, relationships and investment and operating experience will allow us to generate an attractive transaction for our stockholders.

There are no family relationships between any Company director or executive officer.

Number and Terms of Office of Officers and Directors

We have five directors, with each director holding office for a two-year term. Prior to the completion of our initial business combination, any vacancy on the board of directors may be filled by a nominee chosen by holders of a majority of our shares of Class B Common Stock. In addition, prior to the completion of our initial business combination, holders of a majority of our shares of Class B Common Stock may remove a member of the board of directors for any reason.

216

Our officers are appointed by the board of directors and serve at the discretion of the board of directors. Our board of directors is authorized to appoint persons to the offices set forth in our bylaws as it deems appropriate. Our bylaws provide that our officers may consist of a Chief Executive Officer, President, Chief Financial Officer, Vice Presidents, Treasurer, Secretary, and such other offices as may be determined by the board of directors.

Director Independence

Nasdaq listing rules require that a majority of our board of directors be independent. An “independent director” is defined generally as a person other than an officer or employee of the company or its subsidiaries or any other individual having a relationship, which, in the opinion of the company’s board of directors, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director. We have three “independent directors” as defined in the Nasdaq listing rules and applicable SEC rules. Our board has determined that each of David Epstein, Jay Flatley and Deep Nishar, are independent directors under applicable SEC and Nasdaq listing rules. Our independent directors will have regularly scheduled meetings at which only independent directors are present. Each of our independent directors owns approximately 1.91% of the outstanding equity of our Sponsor.

Executive Officer and Director Compensation

In no event will our existing officers or directors receive any other cash- or equity-based compensation or be paid any finder’s fee, reimbursement, consulting fee or monies in respect of any payment of a loan by the Company prior to, or in connection with any services rendered for any services they render in order to effectuate, the completion of our initial business combination (regardless of the type of transaction that it is), other than reimbursements for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. We do not have a policy that prohibits our Sponsor, officers or directors, or any of their respective affiliates, from negotiating for the reimbursement of out-of-pocket expenses by a target business. Any such payments prior to an initial business combination will be made using funds held outside the Trust Account. Other than quarterly audit committee review of such payments, we do not expect to have any additional controls in place governing our reimbursement payments to our directors and officers for their out-of- pocket expenses incurred in connection with identifying and consummating an initial business combination.

After the completion of our initial business combination, directors or members of our management team who remain with us may be paid consulting or management fees or receive equity or equity-based awards from the Combined Company. These fees and awards (if any) will be disclosed to stockholders in accordance with applicable rules and regulations, to the extent then known, in the tender offer materials or proxy solicitation materials furnished to our stockholders in connection with a proposed initial business combination. We have not established any limit on the amount of such fees that may be paid by the Combined Company to our directors or members of management. It is unlikely the amount of such compensation will be known at the time of the proposed initial business combination, because the directors of the post-combination business will be responsible for determining officer and director compensation. Any compensation to be paid to our officers will be determined, or recommended to the board of directors for determination, either by a compensation committee constituted solely by independent directors or by a majority of the independent directors on our board of directors.

We do not intend to take any action to ensure that members of our management team maintain their positions with us after the consummation of our initial business combination, although it is possible that some or all of our officers and directors may negotiate employment or consulting arrangements to remain with us after our initial business combination. The existence or terms of any such employment or consulting arrangements to retain their positions with us may influence our management team’s motivation in identifying or selecting a target business but we do not believe that the ability of our management to remain with us after the consummation of our initial business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our officers and directors that provide for payments or benefits upon termination of employment.

217

Committees of the Board of Directors

Our Board has two standing committees: an audit committee and a compensation committee. Both our audit committee and our compensation committee are comprised solely of independent directors.

Audit Committee

We have established an audit committee of the board of directors. The members of our audit committee are David Epstein, Jay Flatley and Deep Nishar. Mr. Epstein serves as chairman of the audit committee. Messrs. Epstein, Flatley, and Nishar are independent of and unaffiliated with our Sponsor and our underwriter. Under Nasdaq listing standards and applicable SEC rules, all the directors on the audit committee must be independent.

Each member of the audit committee is financially literate and our board of directors has determined that David Epstein qualifies as an “audit committee financial expert” as defined in applicable SEC rules and has accounting or related financial management expertise.

We have adopted an audit committee charter, which details the principal functions of the audit committee, including:

•

assisting board oversight of (1) the integrity of our financial statements, (2) our compliance with legal and regulatory requirements, (3) the independent registered public accounting firm’s qualifications and independence and (4) the performance of our internal audit function and the independent registered public accounting firm;

•

the appointment, compensation, retention, replacement, and oversight of the work of the independent registered account firm engaged by us;

•

pre-approving all audit and permitted non-audit services to be provided by the independent registered public accounting firm engaged by us, and establishing pre-approval policies and procedures;

•

setting clear hiring policies for employees or former employees of the independent registered public accounting firm, including but not limited to, as required by applicable laws and regulations;

•

setting clear policies for audit partner rotation in compliance with applicable laws and regulations;

•

obtaining and reviewing a report, at least annually, from the independent registered public accounting firm describing (i) the independent registered public accounting firm’s internal quality-control procedures, (ii) any material issues raised by the most recent internal quality-control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities within the preceding five years respecting one or more independent audits carried out by the firm and any steps taken to deal with such issues and (iii) all relationships between the independent registered public accounting firm and us to assess the independent registered public accounting firm’s independence;

•

meeting to review and discuss our annual audited financial statements and quarterly financial statements with management and the independent registered public accounting firm, including reviewing our specific disclosures under “DYNS Management’s Discussion and Analysis of Financial Condition and Results of Operations;”

•

reviewing and approving any related party transaction required to be disclosed pursuant to Item 404 of Regulation S-K promulgated by the SEC prior to us entering into such transaction; and

•

reviewing with management, the independent registered public accounting firm, and our legal advisors, as appropriate, any legal, regulatory or compliance matters, including any correspondence with regulators or government agencies and any employee complaints or published reports that raise material issues regarding our financial statements or accounting policies and any significant changes in accounting standards or rules promulgated by the Financial Accounting Standards Board, the SEC or other regulatory authorities.

218

Nominating Committee

We do not have a standing nominating committee though we intend to form a corporate governance and nominating committee as and when required to do so by law or Nasdaq rules. In accordance with Rule 5605 of the Nasdaq rules, a majority of the independent directors may recommend a director nominee for selection by the board of directors. The board of directors believes that the independent directors can satisfactorily carry out the responsibility of properly selecting or approving director nominees without the formation of a standing nominating committee. The directors who will participate in the consideration and recommendation of director nominees are David Epstein, Jay Flatley and Deep Nishar. In accordance with Rule 5605 of the Nasdaq rules, all such directors are independent. As there is no standing nominating committee, we do not have a nominating committee charter in place.

The Board will also consider director candidates recommended for nomination by our stockholders during such times as they are seeking proposed nominees to stand for election at the next annual meeting of stockholders (or, if applicable, a Special Meeting of stockholders). Our stockholders that wish to nominate a director for election to our board of directors should follow the procedures set forth in our bylaws.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, the board of directors considers educational background, diversity of professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our stockholders.

Compensation Committee

We have established a compensation committee of the Board. The members of our compensation committee are David Epstein, Jay Flatley and Deep Nishar. Mr. Flatley serves as chairman of the compensation committee. Messrs. Epstein, Flatley and Nishar are independent of and unaffiliated with our Sponsor and our underwriter. Under Nasdaq listing standards, all the directors on the compensation committee must be independent.

We have adopted a compensation committee charter, which details the principal functions of the compensation committee, including:

•

reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, if any is paid by us, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

•

reviewing and making recommendations on an annual basis to our board of directors with respect to (or approving, if such authority is so delegated by our board of directors) the compensation, if any is paid by us, and any incentive-compensation and equity-based plans that are subject to board approval of our other officers;

•

reviewing on an annual basis our executive compensation policies and plans;

•

implementing and administering our incentive compensation equity-based remuneration plans;

•

assisting management in complying with our proxy statement and annual report disclosure requirements;

•

approving all special perquisites, special cash payments and other special compensation and benefit arrangements for our officers and employees;

•

if required, producing a report on executive compensation to be included in our annual proxy statement; and

•

reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors.

219

Until the earlier of the consummation of our initial business combination or our liquidation and in connection with potentially providing financing or other investments in connection with our initial business combination, no compensation of any kind, including finders, consulting or other similar fees, will be paid to any of our existing stockholders, officers, directors or any of their respective affiliates, prior to, or for any services they render in order to effectuate the consummation of an initial business combination. Accordingly, it is likely that prior to the consummation of an initial business combination, the compensation committee will only be responsible for the review and recommendation of any compensation arrangements to be entered into in connection with such initial business combination.

The charter also provides that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by Nasdaq and the SEC.

Compensation Committee Interlocks and Insider Participation

None of our executive officers currently serves, and in the past year has not served, as a member of the compensation committee of any entity that has one or more executive officers serving on our Board.

Code of Ethics

We have adopted a Code of Ethics applicable to our directors, officers and employees, a copy of which is available on our website. In addition, a copy of the Code of Ethics will be provided without charge upon request from us. We intend to disclose any amendments to or waivers of certain provisions of our Code of Ethics in a Current Report on Form 8-K.

Conflicts of Interest

Subject to pre-existing fiduciary or contractual duties as described below, our officers and directors have agreed to present any business opportunities presented to them in their capacity as a director or officer of DYNS to us. Certain of our officers and directors presently have fiduciary or contractual obligations to other entities pursuant to which such officer or director is or may be required to present a business combination opportunity. Accordingly, if any of our officers or directors becomes aware of a business combination opportunity which is suitable for an entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such opportunity to such entity. We believe, however, that the fiduciary duties or contractual obligations of our officers or directors will not materially affect our ability to complete our initial business combination. Our Current Charter provides that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of DYNS and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and to the extent the director or officer is permitted to refer that opportunity to us without violating another legal obligation. Further, we do not believe that these conflicts materially impacted DYNS’s search for an initial business combination target because our Sponsor, officers and directors have significant experience in identifying and executing multiple acquisition opportunities simultaneously and were not limited by industry or geography in terms of the acquisition opportunities they could pursue.

Potential investors should also be aware of the following other potential conflicts of interest:

•

None of our officers or directors is required to commit his or her full time to our affairs and, accordingly, may have conflicts of interest in allocating his or her time among various business activities.

220

•

In the course of their other business activities, our officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to us as well as the other entities with which they are affiliated. Our management may have conflicts of interest in determining to which entity a particular business opportunity should be presented.

•

Our Sponsor, and each of our officers and directors have agreed to (i) waive their redemption rights with respect to their Founder Shares, Private Placement Shares and any Public Shares held by them in connection with the completion of our initial business combination, (ii) waive their redemption rights with respect to their Founder Shares, Private Placement Shares and any Public Shares held by them in connection with a stockholder vote to approve an amendment to our amended and restated certificate of incorporation (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our Public Shares if we do not complete our initial business combination within 24 months from the closing of this offering or (B) with respect to any material provision relating to stockholders’ rights and (iii) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares and Private Placement Shares if we fail to complete our initial business combination within 24 months from the closing of this offering or during any stockholder-approved extension period, although they will be entitled to liquidating distributions from the trust account with respect to any Public Shares they hold if we fail to complete our initial business combination within the prescribed timeframe. If we do not complete our initial business combination within such applicable time period, the proceeds of the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of our Public Shares, and the Private Placement Shares will expire worthless. With certain limited exceptions, the Founder Shares (or any shares of Class A Common Stock into which they convert) will not be transferable or assignable until the earlier of: (A) one year after the completion of our initial business combination or (B) subsequent to our initial business combination, (x) if the last reported sale price of our Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination, or (y) the date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of our stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property. With certain limited exceptions, the Private Placement Shares will not be transferable, assignable or saleable by our Sponsor or its permitted transferees until 30 days after the completion of our initial business combination. Since our Sponsor and officers and directors will directly or indirectly own common stock following this offering (including, without limitation, an additional 500,000 shares of Class A Common Stock which certain privately held entities affiliated with certain of DYNS’s officers and directors will subscribe for in the PIPE Investment, on the same terms as the PIPE Investors), our officers and directors may have a conflict of interest in determining whether a particular target business (including Senti) is an appropriate business with which to effectuate our initial business combination.

•

Our officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors was included by a target business as a condition to any agreement with respect to our initial business combination.

•

Our Sponsor, officers or directors may have a conflict of interest with respect to evaluating a business combination and financing arrangements as we may obtain loans from the Sponsor or an affiliate of the Sponsor or any of our officers or directors to finance transaction costs in connection with an intended initial business combination. As of the date of this proxy statement/prospectus, no such loans are outstanding. The terms of such loans, if any are made, have not been determined and no written agreements exist with respect to such loans. The loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such loans may be converted into shares of the post-business combination entity at a price of $10.00 per share at the option of the lender, and it is expected that the shares issued upon conversion of such loans would be identical to the Private Placement Shares.

221

The conflicts described above may not be resolved in our favor. You should also read the section entitled “Summary of the Proxy Statement/Prospectus—Interests of the Sponsor and DYNS’s Directors and Officers in the Business Combination,” above, for additional information regarding potential conflicts of interest.

In general, officers and directors of a corporation incorporated under the laws of the State of Delaware are required to present business opportunities to a corporation if:

•

the corporation could financially undertake the opportunity;

•

the opportunity is within the corporation’s line of business; and

•

it would not be fair to our company and its stockholders for the opportunity not to be brought to the attention of the corporation.

Accordingly, as a result of multiple business affiliations, our officers and directors may have similar legal obligations relating to presenting business opportunities meeting the above-listed criteria to multiple entities. Furthermore, our Current Charter provides that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of our company and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and to the extent the director or officer is permitted to refer that opportunity to us without violating another legal obligation.

Morgan, which served as the sole underwriter of our Initial Public Offering, capital markets advisor to DYNS in respect of the Business Combination and co-placement agent in connection with the PIPE Investment.

Limitation on Liability and Indemnification of Officers and Directors

Our Current Charter provides that our officers and directors will be indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended. In addition, our Current Charter provides that our directors will not be personally liable for monetary damages to us or our stockholders for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to us or our stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

We have entered into agreements with our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our Current Charter. Our bylaws also permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware law would permit such indemnification. We have purchased a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against officers and directors, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

We believe that these provisions, the directors’ and officers’ liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Executive and Director Compensation

None of our officers has received any cash compensation for services rendered to us. No compensation of any kind, including any finder’s fee, reimbursement, consulting fee or monies in respect of any payment of a loan, will be paid by us to the Sponsor, officers or directors or any affiliate of the Sponsor, officers or directors, prior to, or in connection with any services rendered in order to effectuate, the consummation of our initial business combination (regardless of the type of transaction that it is). However, these individuals will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to the Sponsor, officers or directors or our or their affiliates. Any such payments prior to an initial business combination will be made using funds held outside the Trust Account. Other than quarterly audit committee review of such payments, we do not expect to have any additional controls in place governing our reimbursement payments to our directors and executive officers for their out-of-pocket expenses incurred in connection with identifying and consummating an initial business combination.

224

retain their positions with us may influence our management’s motivation in identifying or selecting a target business but we do not believe that the ability of our management to remain with us after the consummation of our initial business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our officers and directors that provide for benefits upon termination of employment.

BUSINESS

Overview

We are a preclinical biotechnology company developing next-generation cell and gene therapies engineered with our gene circuit platform technologies to fight challenging diseases. Our mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, we have built a synthetic biology platform that we believe may enable us to program next-generation cell and gene therapies with what we refer to as “gene circuits.” These gene circuits, which we created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. We aim to design and optimize gene circuits through our Design-Build-Test-Learn Engine, or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Our gene circuit platform technologies are designed to be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (TILs), stem cells including Hematopoietic Stem Cells (HSCs), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of our current product candidates are in preclinical development. Our lead product candidates utilize allogeneic chimeric antigen receptor (CAR) NK cells outfitted with our gene circuit technologies in several oncology indications with currently high unmet need. Subject to the successful completion of IND- enabling studies, we expect to file investigational new drug applications, or INDs, for multiple product candidates starting in 2023.

The field of synthetic biology has evolved rapidly over the past few decades, and we believe that we are uniquely positioned to harness its potential to drive significant advances in medicine. Our scientific team is comprised of leaders in the space, and we have leveraged their expertise to create our scalable DBTL Engine and develop a proprietary knowledge database for therapeutic gene circuits. Our founders, Dr. Tim Lu, Dr. Philip Lee, Prof. James Collins, and Prof. Wilson Wong are pioneers in synthetic biology, gene circuits and cell and gene therapy, each having spent over twenty years advancing next-generation technologies in these areas. Our scientific founders and advisors are among the foremost leaders in their respective fields, having collectively published many of the seminal scientific papers in synthetic biology in top journals such as Nature, Science and Cell. Integrating disciplines from biology, chemistry and computer science, we have leveraged recent advances in DNA sequencing and synthesis, high-throughput experimentation and computational design, together with our intellectual property, to design, build and test gene circuits. We believe these are novel technologies, and we are not aware of U.S. Food and Drug Administration, or FDA, approved therapeutics utilizing similar technologies. As a result, these technologies may require significant resources in order to achieve regulatory approval. In preclinical studies, we have shown that our gene circuits are capable of carrying out sophisticated biological functions in a variety of disease models and we are preparing to advance our product candidates to clinical studies. We believe in the potential of gene circuits to enhance efficacy, precision and control of numerous cell and gene therapy products. Ultimately, we envision that cells running computations using our gene circuits in the human body will be able to outsmart a myriad of complex diseases.

The following figure illustrates how our gene circuit platform technologies may enable the creation of smarter medicines that can “sense inputs,” “compute decisions” and “respond with outputs” to impact diseases:

Key Challenges to Existing Disease Treatments and Our Gene Circuit Solutions

Key Challenges to Existing Disease Treatments

Diseases often involve complex biological interactions, which limit the effectiveness of existing therapeutics that only have single mechanisms of action and are unable to adapt to dynamic disease states. We characterize these key challenges in the following four categories:


		Target Heterogeneity: Many diseases are heterogeneous and express antigens that are also present on healthy cells. The overlap of antigen expression on diseased and healthy cells limits the ability of existing therapies to target diseased cells at therapeutically relevant doses due to undesirable effects against healthy cells. For example, most cancers do not have a single antigen target that is uniformly expressed on all cancer cells with limited to no expression on non-cancerous cells. Thus, the ability to precisely distinguish between diseased cells and healthy cells has been a central challenge to date with current therapeutic approaches that do not encode logic, such as monoclonal antibodies, antibody-drug conjugates and single-target CAR therapies. Modalities that can respond to multiple biomarkers, rather than just a single one, have the potential to open up the opportunity for more precise and efficacious medicines.
		Disease Evasion: Disease pathologies are multifaceted. For example, diseases can evade the immune system or acquire resistance to single-target treatments by activating other biological pathways. The tumor microenvironment of many solid tumors suppresses cancer-fighting immune cells via multiple pathways. To overcome these complex barriers, combination therapies that utilize multiple individual drugs are being explored clinically. However, manufacturing issues, regulatory aspects, pharmacology complexities and clinical challenges of using multiple individual drugs together can be difficult. A gene or cell therapy with the ability to activate multiple anti-tumor pathways within a single product could help limit disease evasion and may improve the durability of responses to treatment, while simplifying the translational path.
		Narrow Therapeutic Window: Once administered to a patient, conventional medicines, including cell and gene therapies, cannot be tuned up or down, which makes it difficult to find the optimal dose, especially for diseases that have a narrow therapeutic window. The ability to create therapeutics that can be titrated or regulated in vivo in the patient may lead to enhanced efficacy and safety.

227


		Dynamic Disease Conditions: Disease conditions are dynamic and vary in space and time. For example, diseases may manifest only in certain tissues, or have a waxing and waning progression over time. Conventional therapies are (i) static, (ii) have a predefined activity around a single mechanism of action that cannot be modified post-administration and (iii) do not adapt to these dynamic conditions, thus limiting their efficacy, specificity and safety. For example, current cell and gene therapies are not dynamic or highly specific, thus limiting the indications that they can address. Developing dynamic therapeutics that are able to sense, and respond to, these spatially or temporally varying conditions would address this challenge.

Our Gene Circuit Solutions

We believe that our core gene circuit platform technologies may enable us to engineer smarter medicines. These technologies can be categorized as follows.


		Logic Gating: Logic Gating gene circuits are designed to enable cell and gene therapies to control their therapeutic activity in response to the presence or absence of multiple disease biomarkers. Below are examples of Logic Gates applied to cancer, although Logic Gating may also be applied to various other disease indications.
				NOT GATE: NOT GATE gene circuits are designed to widen the therapeutic window by enabling effective killing of cancer cells while preserving healthy cells. The NOT GATE functions by recognizing Safety Antigens (SAs), or antigens that are selectively expressed on healthy cells and not on cancer cells, thus limiting on-target, off-tumor killing. By protecting healthy cells, the NOT GATE has the potential to enable more effective on-target, on-tumor killing of tumor cells that express Tumor-Associated Antigens (TAAs). Generally, existing cancer drugs target only a single antigen, which means they can only be effectively and safely used in situations where that antigen is uniquely expressed on tumors and not in healthy cells, or where the on-target, off-tumor effects are tolerable.
				OR GATE: OR GATE gene circuits are designed to address tumor heterogeneity and limit antigen escape. The OR GATE functions by killing tumor cells that express any one of multiple antigens. Generally, current medicines are unable to address more than one target at a time and are thus susceptible to tumor evasion.
				AND GATE: AND GATE gene circuits require that multiple targets be present at the same time to trigger killing of cancer cells, which may enhance the specificity of on-target, on-tumor activity. Generally, conventional therapies only recognize a single antigen for their activity, which can result in a lack of specificity.
		Multi-Arming: Multi-Arming gene circuits are designed to incorporate multiple payloads into a single cell or gene therapy product. These gene circuits are intended to activate various biological pathways in complementary ways to prevent diseases from evading single-target treatments, and thereby potentially improve treatment efficacy. Existing combination therapies that target complex diseases require the application of multiple individual drugs, which is difficult due to research, clinical development, regulatory and pharmacology barriers.
		Regulator Dial: Regulator Dial gene circuits are designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, this can be implemented by regulating therapeutic payload expression in response to varying concentrations of FDA-approved drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene therapies even after they have been delivered in vivo. Existing cell and gene therapies cannot be modulated once they have been delivered into patients.

228


		Smart Sensor: A Smart Sensor is a gene circuit, or combination of gene circuits, designed to precisely detect distinct cell types or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before responding with a specific therapeutic response. Conventional medicines are generally unable to dynamically change their behavior in response to cell or disease specific conditions.

We believe we can rationally combine any of these four gene circuit platform technologies to strategically customize therapeutics to outmaneuver complex diseases. The following figure maps how our gene circuit platform technologies are designed to address specific challenges facing existing medicines:

LOGO

We Believe Our Gene Circuits May Have Broad Applicability in Multiple Treatment Modalities and Disease Areas

We have conducted research in multiple cell types and vector types, and the initial focus of our internal pipeline is implementing gene circuits within allogeneic CAR-NK cells.

Disease Areas: We believe our gene circuits can be customized to address many aspects of disease biology. We have demonstrated and published on applications of gene circuits across many different in vivo disease models. Thus, we believe that our gene circuit platform technologies have the potential to be used for a broad range of diseases that span therapeutic areas such as oncology, immunology, genetic diseases, neurology, cardiology, metabolic diseases, ophthalmology and regenerative medicine.

229

The following figure presents our perspective on how our gene circuit technologies can be utilized across modalities and corresponding therapeutic areas:

LOGO

We Utilize Our Design-Build-Test-Learn Engine to Optimize Our Gene Circuits

We have established, and continue to scale, our powerful DBTL Engine to generate our therapeutic gene circuits. We believe the speed, quantity and quality by which we can design multiple types of gene circuits, resulting in thousands of functional gene circuits engineered to date, is unique to our platform. Our gene circuits are engineered by an expert team of synthetic biologists informed by proprietary bioinformatics and our internal gene circuits knowledge database. This proprietary knowledge database contains quantitative characterization data on gene circuits we have previously built, including those that are functional and those that are not. Thus, this database helps inform the design of future gene circuits guided by our past experiences. Furthermore, we leverage machine learning approaches to continually enhance the design of such gene circuits based on data generated through testing in our in vitro and in vivo disease models. The breadth and scale of our DBTL Engine allows us to learn from each cycle of design to improve the speed and quality of future designs—even across projects and modalities. This approach leverages and reinforces our position as leaders and innovators in the field of synthetic biology for the development of human therapeutics. Based on decades of experience among our founders as well as the accumulated data from our DBTL Engine, we believe that our approach to programming gene circuits is broadly applicable toward engineering optimal efficacy, precision and control into many cell or gene-based medicines.

The following figure provides an overview of the key steps in our DBTL Engine process:

Our Pipeline and Product Candidates

We believe that our gene circuits will enable us to address indications that conventional small molecule, protein and cell and gene therapies cannot. We intend to seek feedback from the FDA and comparable regulatory authorities given the novelty of our technologies, which could make the regulatory pathway more complex and potentially time-consuming than for more well-known therapeutics. Our most advanced gene-circuit product candidates are directed at allogeneic CAR-NK cells for oncology. In addition to these product candidates, we have discovery stage product candidates focused on gene therapies for tissue-directed targets and cell therapies for regenerative medicines. The following pipeline chart depicts our preclinical stage product candidates.

LOGO

SENTI-202

We are developing our SENTI-202 product candidate as a Logic Gated (OR + NOT) allogeneic CAR-NK cell therapy designed to target and eliminate acute myeloid leukemia, or AML, cells while sparing the healthy bone marrow. We are engineering SENTI-202 to express a bivalent CAR as an OR GATE directed against the Tumor-Associated Antigens, Fms-like tyrosine kinase 3 (FLT3) or Cluster of Differentiation 33 (CD33), where one or both are expressed in 95% of AML patients. FLT3 is highly expressed on leukemic stem cells, or LSCs, while CD33 is highly expressed on AML blasts. AML is a heterogeneous disease composed of both AML LSCs and blasts. Thus, we believe that targeting FLT3 OR CD33 will enhance the overall killing activity against diseased cells in AML. However, FLT3 is also expressed on healthy hematopoietic stem cells, or HSCs, in the bone marrow. In order to spare FLT3-expressing healthy HSCs, we have further engineered SENTI-202 with a NOT GATE gene circuit comprised of an inhibitory CAR, or iCAR, targeted against endomucin, or EMCN. EMCN is a Safety Antigen with high expression on HSCs and low expression on AML LSCs and blasts. We believe this NOT GATE gene circuit could allow SENTI-202 to eliminate LSCs that cause relapse while

231

preserving the patient’s HSCs. This proprietary product profile has the potential to drive towards a cure for AML without the need for a bone marrow transplant by enabling killing of diverse AML cells while sparing HSCs that regenerate the blood and the immune systems. We are also engineering SENTI-202 with an aim to express our proprietary calibrated release interleukin 15, or crIL-15, to promote NK cell persistence and tumor killing. Our crIL-15 construct is being designed to simultaneously produce both membrane associated and fully secreted IL-15 proteins, which creates potential for more optimal cytokine signaling.

In 2022, we plan to present IND-enabling pharmacological data at key scientific conferences, seek feedback from the FDA through a pre-IND meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the clinical evaluation of SENTI-202.

SENTI-301

Our SENTI-301 product candidate is a Multi-Armed allogeneic CAR-NK cell therapy that we are developing for the treatment of hepatocellular carcinoma, or HCC. We are engineering NK cells to target glypican 3, or GPC3, which is highly expressed in 70% to 90% of HCCs and has low or no expression on normal adult tissues. SENTI-301 is armed with a combination of immuno-stimulatory payloads intended to promote expansion and persistence of our CAR-NK cells, as well as activation and recruitment of endogenous immune cells into the solid tumor microenvironment for enhanced anti-tumor activity. One of the immuno-stimulatory payloads is our proprietary crIL-15 protein. crIL-15 is designed for enhanced cytokine signaling to promote NK cell persistence and tumor killing. We are further working to engineer SENTI-301 with the capability to produce the potent immune effector interleukin 12, or IL-12, where expression is modulated via a small-molecule Regulator Dial gene circuit.

SENTI-401

Our SENTI-401 product candidate is a Logic Gated allogeneic CAR-NK cell therapy that we are developing to more precisely target and eliminate colorectal cancer, or CRC, cells while sparing healthy cells elsewhere in the body. We are engineering NK cells to express a CAR directed against carcinoembryonic antigen, or CEA, which is highly overexpressed in 85% to 90% of colorectal cancer but is also expressed in epithelial cells in healthy tissues. The expression profile of CEA in both tumor and healthy cells has resulted in on-target, off-tumor toxicities with conventional CEA-targeted therapies, thus limiting their clinical success. To address this challenge, we are engineering SENTI-401 with a NOT GATE implemented via an iCAR targeted against an epithelial cell Safety Antigen called V-set and Immunoglobulin Domain Containing 2, or VSIG2. Thus, the SENTI-401 product candidate’s Logic Gating is intended to more effectively treat CRC patients by targeting a well-known Tumor-Associated Antigen, CEA, and widen the therapeutic window by preventing killing when CEA appears on healthy cells that also expresses the VSIG2 Safety Antigen.

In 2023, we plan to present IND-enabling pharmacological data at key scientific conferences and seek feedback from the FDA through a pre-IND meeting.

232

Our Discovery Stage Programs

Our current discovery stage programs are as follows:

LOGO

We believe our gene circuits can be readily adapted to new disease contexts to enable a variety of additional CAR-NK product candidates that address important cancers. Our SENTI-411 and SENTI-421 product candidates are Logic Gated CAR-NKs that leverage the same NOT GATE gene circuit technology deployed in SENTI-202 and SENTI-401. We are developing these product candidates for precise targeting of solid or liquid tumors expressing certain Tumor-Associated Antigens, while protecting against on-target, off-tumor toxicity toward healthy cells in order to widen the therapeutic window. Additionally, our SENTI-311 product candidate is a CAR-NK that utilizes our Multi-Arming gene circuit technology currently deployed in our SENTI-301 product candidate. SENTI-311 is being developed for the treatment of solid tumors, where Multi-Arming is designed to overcome disease evasion.

Furthermore, we are actively pursuing the nomination and development of multiple product candidates that harness the full breadth of our gene circuit platform beyond Logic Gating and Multi-Arming of allogeneic CAR-NK cells within oncology. In particular, we have entered into collaborations with Spark Therapeutics, Inc. (acquired by Roche Holding AG) for the design of Smart Sensors for disease- and tissue-specific gene therapy, and with Bluerock Therapeutics LP (acquired by Bayer AG) for the use of Smart Sensors and Regulator Dials for regenerative medicines.

Our Gene Circuit Application to Allogeneic, NK Cells for Oncology

Our initial pipeline focus is on the application of our gene circuit platform technologies towards improving the treatment of specific oncology indications. Our most advanced product candidates are allogeneic, gene circuit-engineered CAR-NK cells. We have chosen to engineer NK cells with our gene circuits based on our belief that NK cells confer the following advantages in relation to other potential immune cell types in oncology:

•

Innate Killing: NK cells naturally carry multiple activating and inhibitory receptors that enable them to innately kill tumor cells while sparing healthy tissues. Furthermore, NK cells have been engineered with CARs to enhance their targeted killing activity. We leverage these features to create Logic Gated CAR-NKs, such as OR GATE CAR-NKs that enhance the killing of heterogeneous tumors and NOT GATE CAR-NKs that spare healthy cells from undesired toxicity and thereby potentially improve on-target, on-tumor killing.

•

Immune Activation: NK cells have been shown to support robust activation of anti-tumor immune pathways via proinflammatory cytokine and chemokine secretion. We leverage this feature with our

233

Multi- Arming gene circuits to further improve their ability to trigger endogenous, complementary anti-tumor activity by engaging the rest of the tumor immunity cycle.

•

Validated Clinical Activity and Tolerability: Allogeneic, as in healthy donor-derived, CAR-NK cells have been recently shown in the clinical setting to have the potential to promote effective anti-tumor activity along with low risks of graft versus host disease, or GvHD, severe cytokine release syndrome, or CRS, and neurotoxicity.

•

Broad Patient Access: We have established proprietary protocols to derive NK cells from healthy donors, manufacture them at scale with a projected low cost, and cryopreserve them with high retained viability post-thaw. As a result, we believe that CAR-NK cells have the potential to be broadly accessible to patients as they may be delivered rapidly to patients in an off-the-shelf manner and in an outpatient setting.

Our Calibrated Release (cr) Technology

Current technologies for arming immune cells with cytokines are limited to either expressing the fully secreted natural form of the protein to support trans- or paracrine signaling, or expressing a membrane-tethered version to promote cis- or autocrine signaling. As a result, we believe these first-generation constructs are unable to efficiently stimulate the engineered cell product and surrounding immune cells, such as those cells from the endogenous immune system, at the same time.

We have created a novel engineered protein technology called calibrated release (cr). We are using this approach to improve IL-15 signaling in our CAR-NK platform. Our crIL-15 engineered cytokine is tethered to the NK cell via a cleavable linker that can be cut off by a ubiquitously expressed protease on the cell surface of NK cells. The rate of linker cleavage can be calibrated by engineering the sensitivity of the cleavable linker sequence to the cell surface protease, enabling us to tune the ratio of membrane-tethered versus fully secreted protein. We believe this platform is generalizable to other proteins, including other cytokines like IL-12.

We Are Building Manufacturing Capabilities That May Enable Production of Off-The-Shelf Cell Therapies

Internal manufacturing capabilities are central to our business strategy, since they can enable us to control the quality and supply of our allogeneic CAR-NK cell therapies for clinical studies and ultimately commercialization. A key advantage of allogeneic cell therapies, versus autologous products that use each patient’s own cells, is the ability to manufacture large batches of drug product from healthy donor cells that can be produced in advance of clinical use, and then stored in frozen vials. Upon commercialization, we expect to be able to make our cell therapies, if approved, broadly accessible in an off-the-shelf manner to cancer patients.

Our corporate headquarters is located in South San Francisco, CA, where we lease approximately 40,000 square feet of research and development and corporate office space. In this location, we have approximately 10,000 square feet dedicated to manufacturing development labs. We have established research and development teams with extensive experience in cell and gene therapy manufacturing operations, including vector process development, cell process development, analytical development, quality control and quality assurance. In June 2021, we signed a lease agreement for a property in Alameda, California and have commenced construction of a Current Good Manufacturing Practices, or cGMP, facility to support clinical and commercial-scale manufacturing of multiple allogeneic CAR-NK cell product candidates.

This manufacturing facility is being designed as a customized end-to-end manufacturing solution to give us the ability to isolate NK cells, engineer these cells with proprietary gene circuits, perform cell culture expansion in large batches, and cryopreserve and store the final cGMP products. We anticipate that this facility will become operational in time to support initial clinical trials for our lead product candidates. We plan to leverage the latest

234

cell therapy manufacturing technologies as we strive to optimize quality, maximize scalability and minimize cost. Our initial manufacturing efforts will focus on our two lead product candidates, SENTI-202 and SENTI-301.

We expect to complete the first stage of construction for our cGMP manufacturing facility and present an overview of our clinical-scale GMP manufacturing process for gene-circuit-engineered NK cells at key technical conferences in 2022.

We may also leverage our manufacturing facility to expand the application of our gene circuit technology to biomanufacturing in partnership with one or more third parties.

Our experienced manufacturing and process development team has established an innovative process with the potential for efficient and scalable production of our allogeneic CAR-NK cell product candidates. Critical aspects of the cell manufacturing process include the ability to perform the four key steps in the CAR-NK cell manufacturing process as outlined below:

LOGO

Step 1: Source, Isolate and Bank Purified NK Cells as Starting Cells: Starting Cells are obtained from enriching and isolating NK cells from qualified healthy donors.

Step 2: Genetically Engineer Starting Cells with Gene Circuits: We genetically modify our NK cells through a viral vector transduction process focused on enhancing gene circuit expression while minimizing impacts on compromising cell viability or cell expansion.

Step 3: Expand and Scale CAR-NK Cells: Our expansion process is designed to generate large numbers of final product doses per manufacturing batch.

Step 4: Formulate and Cryopreserve CAR-NK Cells: For storage and distribution, we will formulate and cryopreserve our final product to retain viability, persistence and cytotoxic function post-thaw for off-the-shelf use.

Our goal is to become an industry leader in the cell and gene therapy landscape. We are pursuing this goal by advancing our gene circuit platform to discover, develop, manufacture and globally commercialize new classes of cell and gene therapies across therapeutic areas and modalities. To achieve this, we have strategically focused on designing therapeutics to address specific challenges that confound existing disease treatments. We aim to provide smarter medicines to patients, and to execute on this strategy we will continue to build on our extensive capabilities by:

Maximizing the commercial potential of our gene circuit platform technologies via strategic collaborations.

The Need for Synthetic Biology-Based Gene Circuits

For the human body to maintain proper function, cells constantly sense and interpret a variety of inputs, or biological signals, to produce outputs, or biological responses. Diseases emerge when the balance between these biological inputs and outputs become inadequate or inappropriate to maintain a healthy state. Furthermore, diseases can evolve or mutate to evade the human body’s natural defense mechanisms that normally serve as a check against these imbalances. Thus, many diseases progress when the intrinsic ability of cells in the human body to rebalance healthy physiology is insufficient or becomes overactive. We believe that programming cells to better sense and react to disease environments has the potential to enhance our ability to treat diseases and restore healthy phenotypes.

Traditional medicines, such as small molecules and biologics, typically target proteins and block their function. We consider these medicines to be static because they have a predefined activity around a single mechanism of action that cannot be modulated once administered. With some exceptions, most traditional medicines primarily treat disease symptoms or sub-optimally address the underlying disease biology, thus failing to achieve durable cures. In addition, some traditional medicines have on-target, off-tissue effects that limit therapeutic windows and cause safety concerns.

There have been remarkable advances in technologies for reading (sequencing) and writing (synthesizing) DNA over the past few decades. These technologies have aided the biopharmaceutical industry in identifying disease mechanisms and have enabled the programming of cell and gene therapies.

As transformative as the early generations of cell and gene therapies have been, they are currently confined to narrow applications and have been proven effective against only a few monogenic diseases and hematological malignancies. These current approaches are limited to sensing and correcting single disease signatures while providing little control over their dosage, timing or localization. Thus, diseases that are dynamic or multifactorial cannot be readily addressed by existing cell and gene therapy products.

Using our gene circuits, we believe we can design more intelligent cell and gene therapies that (i) can precisely target heterogeneous diseases using Logic Gating, (ii) can be Multi-Armed with complementary payloads to overcome disease evasion, (iii) can be controlled in vivo using Regulator Dials to overcome narrow therapeutic windows and (iv) are equipped with Smart Sensors that dynamically detect disease environments.

237

We believe that by leveraging synthetic biology to engineer gene circuit-enabled cell and gene therapies, we will be able to overcome the shortcomings of the early generations of these genetic medicines

Our Platform: The Opportunity for Gene Circuits

We believe that our gene circuit platform technologies are modality-agnostic and can be deployed in any cell and gene therapy product candidate to improve efficacy, safety and control. Fundamentally, gene circuits reprogram cells to sense key biological signals, compute based on this information and dynamically respond with multiple therapeutic outputs. In contrast to existing single-target or static medicines, this sense-compute-respond paradigm has the potential to enable precise and highly active medicines that can address the complex and dynamic mechanisms underlying important diseases.

Our Gene Circuit Platform Technologies

In our pursuit to create a new generation of smarter medicines, we have built a toolbox of proprietary gene circuit platform technologies that we believe may enhance the risk benefit paradigm of cell and gene therapy products. We are initially focused on four core categories of gene circuits to develop our current and future programs: (i) Logic Gating, (ii) Multi-Arming, (iii) Regulator Dials and (iv) Smart Sensors. Each of our gene circuit platform technologies is designed to confer greater clinical and therapeutic activity, precision and control to cell and gene therapies.

We believe that our core gene circuit platform technologies may enable us to engineer smarter medicines and can be categorized as follows:


		Logic Gating: Logic Gating gene circuits are designed to enable cell and gene therapies to control their therapeutic activity in response to the presence or absence of multiple disease biomarkers. Below are examples of Logic Gates applied to cancer, although Logic Gating may be applied to various other disease indications as well.
				NOT GATE: NOT GATE gene circuits are designed to widen the therapeutic window by enabling effective killing of cancer cells while preserving healthy cells. The NOT GATE functions by recognizing Safety Antigens, or antigens that are selectively expressed on healthy cells and not on cancer cells, thus limiting on-target, off-tumor killing. By protecting healthy cells, the NOT GATE has the potential to enable more effective on-target, on-tumor killing of tumor cells that express Tumor-Associated Antigens. Generally, existing cancer drugs target only a single antigen, which means they can only be effectively and safely used in situations where that antigen is uniquely expressed on tumors and not in healthy cells, or where the on-target, off-tumor effects are tolerable.
				OR GATE: OR GATE gene circuits are designed to address tumor heterogeneity and limit antigen escape. The OR GATE functions by killing tumor cells that express any one of multiple antigens. Generally, current medicines are unable to address more than one target at a time and are thus susceptible to tumor evasion.
				AND GATE: AND GATE gene circuits require that multiple targets be present at the same time to trigger killing of cancer cells, which may enhance the specificity of on-target, on-tumor activity. Generally, conventional therapies only recognize a single antigen for their activity, which can result in a lack of specificity.
		Multi-Arming: Multi-Arming gene circuits are designed to incorporate multiple payloads into a single cell or gene therapy product. These gene circuits are intended to activate various biological pathways in complementary ways to prevent diseases from evading single-target treatments, and thereby potentially improve treatment efficacy. Existing combination therapies that target complex

238


		diseases require the application of multiple individual drugs, which is difficult due to research, clinical development, regulatory and pharmacology barriers.
		Regulator Dial: Regulator Dial gene circuits are designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, this can be implemented by regulating therapeutic payload expression in response to varying concentrations of FDA-approved drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene therapies even after they have been delivered in vivo. Existing cell and gene therapies cannot be modulated once they have been delivered into patients.
		Smart Sensor: A Smart Sensor is a gene circuit, or combination of gene circuits, designed to precisely detect cell type or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before responding with a specific therapeutic response. Conventional medicines are generally unable to dynamically change their behavior in response to cell or disease specific conditions.

We believe we can rationally combine any one of these four gene circuit platform technologies to strategically customize therapeutics to outmaneuver complex diseases.


		Logic Gating

Logic Gating gene circuits are designed to enable cell and gene therapies to control their therapeutic activity in response to the presence or absence of multiple disease biomarkers. This capability has the potential to enable more accurate and efficient targeting of heterogeneous diseased cells while sparing healthy ones. Our initial product candidates for oncology will utilize our NOT GATE and OR GATE gene circuit technology. Furthermore, we believe this technology can be utilized across a broad range of oncology indications. To this end, we have established a proprietary Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform that enables the expansion of our Logic Gating approach against novel Tumor-Associated Antigen and Safety Antigen pairs across multiple cancer indications.

The figure below illustrates the behavior of our Logic Gating gene circuit technologies in CAR-NK cells:

LOGO

239


		NOT GATE

Background: The Need for Precision Targeting

The expression of a single CAR in T cells or NK cells can redirect them to kill cancer cells that express a specific surface antigen. This technology has led to breakthrough therapies for B cell malignancies and multiple myeloma, where targeting of tissue-lineage antigens – CD19 or B Cell Maturation Antigen, or BCMA – rather than Tumor-Associated Antigens, is tolerated. Beyond these initial applications, the lack of uniquely specific tumor antigens presents a great challenge since on-target, off-tumor toxicity to vital tissues significantly limits the cancer indications addressable by single-target CAR-NK or CAR-T therapies. Similar limitations are faced by monoclonal antibodies and antibody-drug conjugates that rely on a single target to discriminate cancer cells from healthy ones.

Our Logic Gating Solution: NOT GATE

The application of CAR-immune cells may be broadened to many cancer types if recognition of a Safety Antigen that is selectively expressed on healthy cells, but not on cancer cells, could selectively block killing against the healthy cells. We believe this feature enables a widened therapeutic window and aggressive treatment of cancers with the potential for enhanced efficacy and reduced risk of undesirable side effects, as well as the expansion of cell therapies into cancer indications where there are no ideal Tumor-Associated Antigens.

As shown in the figure below, we have engineered NK cells with a synthetic NOT GATE gene circuit, where an activating CAR, or aCAR, can drive the killing of cancer cells presenting an activating, Tumor-Associated Antigen, shown in green, while an inhibitory CAR, or iCAR, can suppress cytotoxicity against normal healthy cells that express both the activating Tumor-Associated Antigen and a Safety Antigen, shown in purple.

LOGO

Selected NOT GATE Proof-of-Concept Data

Our NOT GATE is implemented with iCARs, which consist of a Safety Antigen-binding domain and a functional intracellular domain derived from the cytoplasmic tails of inhibitory co-receptors containing immunoreceptor tyrosine-based inhibitory motifs, or ITIMs, which are selected from a library of ITIMs upon testing and evaluation. When a Logic Gated CAR-NK cell encounters a target cell and associates with its cell surface antigens, the aCAR and iCAR “sense” these inputs and provide activating or inhibitory signals into the

240

Logic Gated CAR-NK cell, respectively. Specifically, engagement of the aCAR alone with an activating, Tumor-Associated Antigen triggers an activating signal cascade in the CAR-NK cells that release cytotoxic mediators to kill the cancer cells. When the iCAR recognizes a certain Safety Antigen that is preferentially expressed on healthy cells, an inhibitory signal cascade is triggered in the CAR-NK cells to block the cytotoxic response, thus sparing the healthy cells.

In vivo functional demonstration of our NOT GATE gene circuit is illustrated in the figure below. A group of mice that received xenotransplantation of model Healthy Cells and Cancer Cells at a ratio of 50:50 were treated with NOT GATE CAR-NK cells targeting either a control Safety Antigen not present on the model Healthy Cells, labeled as Control CAR-NK cells, or a Safety Antigen on the model Healthy Cells, labeled as the NOT GATE CAR-NK cells. The Control CAR-NK cells indiscriminately killed both the model Healthy Cells and Cancer Cells in mice. Conversely, the NOT GATE CAR-NK cells selectively killed the Cancer Cells, while sparing the model Healthy Cells. Further analysis showed that treatment with NOT GATE CAR-NK cells resulted in significant enrichment of Healthy Cells in these mice, up from 50% at baseline to approximately 95% after treatment. This data demonstrates that the NOT GATE CAR-NK cells have the potential to spare model Healthy Cells while maintaining killing of model Cancer Cells in vivo.

LOGO

Future Areas of Applications and Alternate Gene Circuits

We believe the enhanced precision enabled by our NOT GATE gene circuit may improve the therapeutic window, and thus the potential efficacy and safety, of our product candidates against the cancer types in our pipeline. Furthermore, the NOT GATE has the potential to significantly increase the applicability of CAR-NK cells against a wide range of liquid and solid tumors that currently do not have ideal Tumor-Associated Antigen targets and are thus currently unaddressed.


		OR GATE

Background: The Need for Targeting Multiple Antigens

Many cancers are heterogeneous, making it difficult to treat them by only targeting a single antigen. For example, the development of targeted AML treatments is difficult due to more than 200 types of chromosome

241

translocations and mutations having been identified in patients. Thus, therapies targeting a single AML-associated antigen are often insufficient to kill all of the tumor subsets, including both AML LSCs and blasts. Consequently, most AML patients treated with these therapies die from disease relapse and progression due to incomplete therapeutic activity. Additionally, due to the highly mutagenic nature of cancer cells, targeting single antigens allows for cancers to more easily escape or acquire resistance to treatment. For example, while recent triumphs of CD19-directed autologous CAR-T therapies have brought renewed hope to patients with relapsed/refractory B cell malignancies, up to 50% of patients with pre-B cell acute lymphoblastic leukemia, or ALL, suffer disease relapse within twelve months after treatment. Many of those patients who relapse toward the latter end of the twelve-month period have cancers that have been associated with loss of the CD19 epitope.

These clinical observations demonstrate the potential benefit of developing therapeutics that are capable of simultaneously targeting multiple Tumor-Associated Antigens across heterogeneous cancers using OR GATE gene circuit technology.

Our Solution and Selected Proof-of-Concept Data: OR GATE

OR GATE gene circuits are designed to simultaneously target multiple Tumor-Associated Antigens. As an example of our OR GATE gene circuits, we have evaluated two forms of OR GATE gene circuits to support our SENTI-202 product candidate, a bicistronic dual CAR architecture and a bivalent CAR architecture.

Bicistronic dual CAR: The bicistronic dual CAR is designed to express two CAR molecules directed against FLT3 and CD33, respectively, two Tumor-Associated Antigens where one or both are expressed in 95% of AML patients. Because CD33 is highly expressed on AML blasts, and FLT3 is highly expressed on LSCs, SENTI-202 offers the potential for elimination of both AML tumor subsets. Using our DBTL Engine, we systematically optimized our OR GATE gene circuit to achieve highly efficient expression of both CAR constructs, as shown in the figures below from top to bottom. Functional proof-of-concept of the OR GATED CAR-NK cells targeting AML is shown in the SENTI-202 pipeline discussion.

LOGO

Bivalent CAR: Bivalent CARs are directed against FLT3 and CD33. The bivalent CAR is a single-chain molecule containing two extracellular binding domains, thus allowing for OR GATE targeting with a single construct. In preclinical mouse models, our FLT3/CD33 bivalent CAR constructs demonstrated significant tumor killing across leukemic cell lines, such as MV4-11, SEM, and HL-60, with differential expression levels of FLT3 and CD33 on their cell surfaces.

242

LOGO


		AND GATE

Our third Logic Gate gene circuit technology is the AND GATE. AND GATE gene circuits require that multiple targets be present at the same time to trigger killing of cancer cells, which may enhance the specificity of on-target, on-tumor activity. Generally, conventional therapies only recognize a single antigen for their activity. We can implement AND GATE gene circuits in multiple formats, including multiple CARs that activate cancer cell killing when two Tumor-Associated Antigen targets are present simultaneously or multiple Smart Sensors that activate gene therapies when two disease-specific promoters are active simultaneously. For example, we have designed cancer gene therapy product candidates that integrate two cancer-specific promoters with an AND GATE to express cytokines, T cell engagers, chemokines and anti-PD1 antibodies in order to trigger powerful and specific anti-cancer responses in mouse models of cancer.


		Multi-Arming

Multi-Arming gene circuits incorporate multiple payloads into a single cell or gene therapy product. These gene circuits are intended to activate various biological pathways in complementary ways to prevent diseases from evading single-target treatments, and thereby improve treatment efficacy. Existing combination therapies that target complex diseases require the application of multiple individual drugs, which is difficult due to research, clinical development, regulatory and pharmacology barriers.

Background: The Need for Targeting Multiple Biological Pathways

Many diseases are difficult to treat since they result from the dysfunction of numerous biological pathways, or they evolve strategies to evade single-target therapies. Combination therapies involving multiple distinct drugs are being used to tackle this problem, but manufacturing, developing and delivering multiple individual drugs into the body is challenging.

243

Our Gene Circuit Solution: Multi-Arming

We believe our Multi-Arming gene circuits can be used to create a single cell or gene therapy product candidate that includes multiple payloads capable of combating multiple disease pathways more effectively. These Multi-Arming gene circuits have the potential to simplify the manufacturing, regulatory and delivery challenges associated with conventional combination therapies. Multi-Arming gene circuits can be controlled by any of our other gene circuit technologies, including Regulator Dials and Logic Gates, to achieve conditional therapeutic activity.

Selected Multi-Arming Proof-of-Concept Data

We have assembled a library of immune-stimulatory payloads—such as cytokines, chemokines and enzymes—that have the potential to trigger anti-tumor responses. As illustrated by the figure below, we leveraged our DBTL Engine to improve the expression of various immune stimulatory payloads in CAR-NK cells, and test the effects of single-armed versus multi-armed CAR-NK cells for their anti-cancer activity.

LOGO

244

The figure below illustrates an example of the benefits of multi-arming. CAR-NK cells were engineered to express either a single cytokine, or multi-armed with both cytokines. These engineered CAR-NK cells were co-cultured with fluorescently labeled tumor cells, and in vitro tumor cell killing was measured over 5 days. While unarmed CAR-NK cells, and single-armed CAR-NK cells, shown by the purple and red lines in the figure, were able to control and reduce tumor cell growth, the multi-armed CAR-NK cells, shown by the teal line in the figure, had greater anti-tumor activity. These results can also be observed by representative fluorescent tumor cell images, shown on the right hand side of the figure, where enhanced tumor killing by the multi-armed CAR-NK cells led to reduced number of tumor cells.

LOGO


		Regulator Dial

Regulator Dial gene circuits are designed to enable the precise tuning of therapeutic activity from a cell or gene therapy product. For example, this can be implemented by regulating therapeutic payload expression in response to varying concentrations of FDA-approved drugs. Regulator Dials are expected to enable the exogenous regulation of next-generation cell and gene therapies in vivo even after they have been delivered. We have generated numerous Regulator Dial gene circuits that can be controlled by a variety of FDA-approved small molecule oral drugs, and that can implement various control behaviors, such as ON switches, OFF switches and rheostats.

Background: The Need for Dynamic Regulation

Existing cell and gene therapies cannot be regulated once they are delivered into the patient. This lack of in vivo control makes it difficult to control dosing within the ideal therapeutic window. This problem makes it challenging to expand cell and gene therapies to many disease indications and to engineer these products to have increased potency and safety. As a result, gene therapies have focused on indications where constitutive expression is acceptable, rather than diseases where expression of the therapeutic payload must be regulated within a specific range or be toggled on and off over a period of time. As another example, CAR-T cell therapies for oncology have exhibited clinical toxicity due to lack of control post-infusion.

The efficacy of adoptive cell therapies in solid tumors is hampered by the poor persistence and dysfunction of these cell therapies in the immunosuppressive tumor microenvironment. Inflammatory cytokines, such as IL-12, have been shown in preclinical studies to enhance CAR-mediated effector functions and stimulate the

245

innate immune response to further support tumor killing. However, clinical trials involving systemic use of IL-12 have shown severe unexpected toxicity, limiting its clinical application. Overexpressing IL-12 from adoptive T cell therapies using a poorly regulated promoter has also resulted in significant clinical toxicities. Beyond toxicity issues, persistent stimulation by inflammatory cytokines has been associated with cell exhaustion and may limit anti-tumor efficacy. Thus, a mechanism to dynamically regulate cytokine production by armored CAR-immune cells could enable enhanced anti-tumor activity without triggering unacceptable levels of toxicity in patients.

Our Gene Circuit Solution: Regulator Dial

One example of our Regulator Dial gene circuit technology is a system designed to regulate gene expression via FDA-approved orally dosed nonstructural protein 3, or NS3, inhibitors. As shown in the figure below, this Regulator Dial consists of a synthetic drug-regulated transcription factor and a synthetic promoter responsive to this regulated transcription factor. In the absence of the drug, the transcription factor is inactive, and no therapeutic protein is produced from the engineered cells. In the presence of the drug, the small molecule triggers expression of the therapeutic protein in a dose-dependent manner—effectively, the Regulator Dial “computes” the level of induction based on the concentration of the drug. Key features of the Regulator Dial, such as (i) basal and maximal expression levels, (ii) thresholds for activation and (iii) input-output gain, can be tuned by our DBTL Engine.

LOGO

246

Selected Regulator Dial Proof-of-Concept Data

Leveraging our DBTL Engine, our NS3-based Regulator Dial was systematically engineered to improve its sensitivity to drug concentration. Optimization of various elements in the Regulator Dial improved the drug sensitivity by approximately tenfold. As illustrated by the figure below, we evaluated the drug sensitivity of our Regulator Dial gene circuit to control the expression of the potent immune effector Il-12. Specifically, this enhanced Regulator Dial gene circuit was triggered at concentrations as low as 0.01 µM of the NS3 inhibitor, grazoprevir, well below the known drug Cmax in humans of 0.23 µM. Thus, we believe that this system could enable control of therapeutic protein production at clinically achievable drug concentrations in a dose-dependent fashion.

LOGO

We have also examined the potential of our Regulator Dial gene circuits in vivo. Using a mouse model to evaluate induction of IL-12 production, Regulator Dial gene circuit-engineered cells were injected intravenously into immunodeficient mice on Day 0. Induction of IL-12 expression in mice was evaluated by treatment with either vehicle control or grazoprevir (GRZ in the figure below). Significant IL-12 induction was observed in mice treated with grazoprevir on Day 4. Upon withdrawal of grazoprevir after Day 4, IL-12 returned to basal level.

LOGO

247

Future Areas of Applications and Alternate Gene Circuits

Beyond the NS3-based Regulator Dial, we have developed and continue to optimize other Regulator Dials. These include Regulator Dials that are controlled by other orally dosed compounds that are FDA-approved or chemicals that are otherwise known as safe, which have differing pharmacology profiles and tissue biodistribution, such as into the central nervous system. These different Regulator Dials can be customized for a variety of cell and gene therapy applications. Conversely, we have created Regulator Dials that are dialed down in response to increasing concentrations of the drug. For example, we have conceptualized and designed various versions of Regulator Dials that have the potential to be regulated by different small molecule drugs, such as Hepatitis C Virus (HCV) protease inhibitors, Immunomodulatory imide drugs, or IMiDs, such as thalidomide and its analogs, and tamoxifen.

LOGO


		Smart Sensor

A Smart Sensor is a gene circuit, or combination of gene circuits, designed to precisely detect cell type or disease environments, and thus distinguish between the “disease state” and “healthy state.” For example, Smart Sensors can be engineered to detect whether certain conditions, or disease biomarkers, are present before responding with a specific therapeutic response. Conventional medicines are generally unable to dynamically change their behavior in response to cell or disease specific conditions.

Diseases change over time and location in the body. Existing therapies are often unable to dynamically change their behavior in response to disease conditions or concentrate their activity only to specific places. Smart Sensors can be designed to sense diverse biomarkers that are specific to disease or cell states, including cell-surface antigens, soluble disease markers, metabolites, transcription factors, microRNAs and others. For example, we have created artificial receptors that are displayed on the surface of engineered cells and activate gene expression within these cells when they encounter specific cytokines or small molecule chemicals. We have also designed gene regulatory elements such as promoters and RNA elements that respond to specific intracellular signals, such as transcription factors and microRNAs.

248

The figure below illustrates how our Smart Sensor gene circuit technology can be used to design synthetic promoters to enable gene therapies that are selectively activated in diseased cells by detecting disease-specific transcription factors:

LOGO

Background: The Need for Novel Sensors in Smart Medicine

Cell and gene therapies have long held out the promise of curing a myriad of diseases, including cancer and genetic disorders. These therapies are generally comprised of three components: (i) the vector, which is used to deliver the transgene into cells; (ii) the promoter, which is a regulatory DNA sequence that drives expression of the transgene; and (iii) a transgene, which is the therapeutic payload.

While early successes in the field have led to recently approved gene therapies, it remains challenging to precisely target gene expression only in diseased cells. This is an important limitation since many genetic disorders require controlled or targeted activity in certain cell types in order to correct diseases while preventing undesirable side effects. Similarly, in cancer gene therapy, it is important to achieve selective killing in cancer cells while sparing healthy tissues. Engineering viral vectors that are biased toward specific cell types is limited by the availability of a unique feature on the outside of the target cell that a viral vector can harness. Additionally, many of the promoters used in current gene therapies are not disease, cell or tissue specific and thus lack the ability to dynamically regulate therapeutic protein production in response to the disease state or location.

Our Smart Sensors Solution: Cell Type or Cell State Specific Conditional Synthetic Promoters

Our solution to address these limitations is to construct Smart Sensors that are selectively activated by cell type or cell state. For example, these Smart Sensors are synthetic promoters that sense internal control mechanisms that cells already possess, such as transcription factors. Transcription factors modulate regulatory elements encoded in the DNA sequence of promoters to direct gene transcription to occur in a specific cell type, or even a specific cell state.

249

LOGO

We have established, and continue to scale, our powerful DBTL Engine to discover highly potent and selective synthetic promoters. As shown in the figure below, our iterative high-throughput process utilizes advanced computational approaches, such as machine learning, to discover these promoters. In the first stage, we perform computational analyses of public and proprietary gene expression datasets to identify transcriptional regulatory elements that are active in a desired, or on-target, cell type and inactive in one or more undesired, or off-target, cell types. Based on these analyses, we computationally design diverse libraries of synthetic, compact promoters that can be synthesized in parallel. For example, we can design libraries containing more than 10,000 promoters that are 200 to 400 base pairs in size, which is significantly smaller than currently used promoters in gene therapies. In the second stage, we perform high-throughput assays to quantify the activities of these promoters in the on-target cell types versus the off-target cell types using next-generation sequencing. This enables us to identify synthetic promoters that are both highly active and specific for the on-target cells. If further optimization is needed, the output of these screens provides a rich source of proprietary data for the machine-learning-enhanced design of additional synthetic promoter libraries, representing the third stage of the process.

LOGO

250

Selected Smart Sensor Proof-of-Concept Data

We have used this high-throughput design platform to generate synthetic promoters for diverse gene and cell therapies. For example, we designed and evaluated, in a high-throughput manner, thousands of synthetic promoters to identify candidates that achieve strong differential expression in breast cancer cells versus healthy breast cells. As shown in the figure below, we were able to validate promoters with very strong selectivity for human breast cancer cells, labeled as Cancer Cell Synthetic Promoter in the figure, versus the healthy breast cells, by up to ~1,000-fold. This level of selectivity is much greater than what we have observed from other cancer-specific promoters of which we are aware. In addition, we also identified healthy-cell-specific promoters, labeled as Healthy Cell Synthetic Promoter in the figure, that are highly selective for healthy breast cells compared to breast cancer cells.

LOGO

Future Areas of Applications and Alternate Gene Circuits

The concept of Smart Sensors that sense disease-specific or tissue-specific transcriptional states is broadly applicable across various therapeutic areas outside of oncology. For example, we believe we can apply our Smart Sensor design platform to create promoters that are selectively activated in certain cells and tissues, such as neurons and muscle. We have also designed microRNA-responsive Smart Sensor elements into mRNA sequences that achieve selective gene expression in desired cells. These Smart Sensors have the potential to enable gene therapies with maximal on-target activity and minimal off-target side effects, thus increasing the therapeutic window of our product candidates.

We have also created artificial receptor architectures that can detect extracellular or cell-surface proteins beyond traditional CARs. These artificial receptor Smart Sensors can be programmed to bind to soluble disease markers, such as cytokines, metabolites, hormones and others, and then modulate gene transcription within cells to drive the appropriate therapeutic response.

We Believe Our Gene Circuits May Have Broad Applicability in Multiple Treatment Modalities and Disease Areas

We believe that our gene circuit platform may have broad applicability across treatment modalities and disease areas.

251

Treatment Modalities: Our gene circuit biological “software” can be used to program numerous cell and gene therapy products, or “hardware.” Specifically, these modalities include NK cells, T cells, TILs, stem cells including HSCs, in vivo gene therapy and mRNA. We have conducted research in multiple cell types and vector types, and the initial focus of our internal pipeline is implementing gene circuits within allogeneic CAR-NK cells.

Disease Areas: Our gene circuits can be customized to address many aspects of disease biology. We have demonstrated and published on applications of gene circuits across many different in vivo disease models. Thus, we believe that our gene circuit platform technologies can be used against a broad range of diseases that span therapeutic areas such as oncology, immunology, genetic diseases, neurology, cardiology, metabolic diseases, ophthalmology and regenerative medicine.

The following figure presents our perspective on how our gene circuit technologies can be utilized across modalities and corresponding therapeutic areas:

We Utilize Our Design-Build-Test-Learn Engine to Optimize Our Gene Circuits

We have established, and continue to scale, our DBTL Engine to generate our therapeutic gene circuits. We believe the speed, quantity and quality by which we can design multiple types of gene circuits, resulting in thousands of functional gene circuits engineered to date, is unique to our platform. Our gene circuits are engineered by an expert team of synthetic biologists informed by proprietary bioinformatics and our internal gene circuits knowledge database. We also leverage machine learning approaches to continually enhance the design of such gene circuits based on data generated through testing in our in vitro and in vivo disease models. The breadth and scale of our DBTL Engine allows us to learn from each cycle of design to improve the speed and quality of future designs—even across projects and modalities. This approach leverages and reinforces our position as leaders and innovators in the field of synthetic biology for the development of human therapeutics. Based on decades of experience among our founders as well as the accumulated data from our DBTL Engine, we believe that our approach to programming gene circuits is broadly applicable toward engineering optimal efficacy, precision and control into many cell or gene based medicines.

The following figure provides an overview of the key steps in our DBTL Engine process:

Our Calibrated Release (cr) Technology

In clinical trials run by other parties unaffiliated with Senti Bio, IL-15 has been shown to improve persistence and maintain a cytotoxic phenotype in NK cells. Another clinical trial of a CAR-NK cell with IL-15 reported clinical efficacy without a systemic increase in circulating IL-15 or toxicity at assessed doses and time points. Previously published studies of tumor resident NK cells collected from HCC patients have also shown that IL-15 can restore NK cell dysfunctions.

Our calibrated release technology is designed to enable the simultaneous expression of tethered IL-15 to promote CAR-NK cell persistence in a cis-acting autocrine fashion, along with secretion of IL-15 to stimulate surrounding immune cells, including both our CAR-NK themselves and other endogenous immune cells in a trans-acting paracrine fashion. This concept is illustrated in the figure below.

LOGO

253

As shown in the figure below, our crIL-15 was shown to improve CAR-NK persistence with a 3-round serial killing assay. Our engineered CAR-NK cells armed with our crIL-15 or the wild-type fully secreted IL-15 (wtIL-15) were co-cultured with tumor cells, which were added at hour 0, hour 96, and hour 168, to repeatedly challenge the CAR-NK cells with fresh cancer target cells. Tumor cell samples without NK cells, shown as the yellow lines, continued to grow. In the first round of tumor killing, CAR-NK cells containing crIL-15, shown in teal, as well as CAR-NK cells containing wtIL-15, shown in pink, effectively killed tumor cells. At 96 and 168 hours, CAR-NK cells were re-challenged with fresh tumor cells. In the second and third rounds of cancer cell killing, which commenced with fresh cancer cells being added at hour 96 and hour 168, only Senti CAR-NK cells armed with crIL-15, shown in teal, maintained their ability to effectively kill tumor cells. This data shows the potential of our calibrated release technology platform to create engineered cytokines that functionally enhance the killing activity of CAR-NK cells in challenging conditions.

SENTI-202 for the Potential Treatment of Acute Myeloid Leukemia

Overview

We are developing our SENTI-202 product candidate as a Logic Gated (OR + NOT) allogeneic CAR-NK cell therapy designed to target and eliminate AML cells while sparing the healthy bone marrow. We are engineering SENTI-202 to express a bivalent CAR as an OR GATE directed against the Tumor-Associated Antigens, FLT3 and CD33, where one or both are expressed in 95% of AML patients. FLT3 is highly expressed on LSCs, while CD33 is highly expressed on AML blasts. AML is a heterogeneous disease composed of both AML LSCs and blasts. Thus, we believe that targeting FLT3 OR CD33 will enhance the overall killing activity against diseased cells in AML. However, FLT3 is also expressed on HSCs in the bone marrow. In order to spare FLT3-expressing healthy HSCs, we have further engineered SENTI-202 with a NOT GATE gene circuit comprised of an iCAR targeted against EMCN. EMCN is a Safety Antigen with high expression on HSCs and low expression on AML LSCs and blasts. We believe this NOT GATE gene circuit could allow SENTI-202 to eliminate LSCs that cause relapse while preserving the patient’s HSCs. Further, SENTI-202 is engineered to express our proprietary crIL-15 effector to promote persistence and more durable antitumor functions. This proprietary product profile has the potential to drive towards a cure for AML without the need for a bone marrow transplant by enabling killing of diverse AML cells while sparing HSCs that regenerate the blood and the immune systems.

Acute Myeloid Leukemia: an Unmet Medical Need

Almost 10% of new cancer cases in the United States each year are hematologic malignancies, including leukemia, lymphoma and myeloma. AML is a type of acute leukemia characterized by an accumulation of malignant immature white blood cells. It is the most common type of acute leukemia in adults, constituting 80% to 85% of cases, and is the second most common—as well as the deadliest—in children. Due to the absence of highly efficacious therapies, AML has the lowest five-year survival rate among all leukemias at just 28.7%. Since the incidence is highest among the elderly, we expect cases and economic burden will continue to rise as the general population ages. According to Dieguez et al., costs for the three years following AML diagnosis can reach $800,000 per patient.

255

Conventional therapy for AML generally involves remission induction therapy, followed by consolidation (post-remission) therapy, in which chemotherapy is used with stem cell transplantation to prevent disease recurrence. For remission induction, treatment options include cytotoxic chemotherapy, radiation therapy and targeted therapies, such as monoclonal antibodies and small molecule inhibitors of disease pathways, with the aim of achieving fewer than 5% blast cells in the bone marrow, blood cell counts within normal limits and no signs or symptoms of disease. Unfortunately, 10% to 40% of patients are unable to achieve these complete remission targets despite intensive induction therapy, and conventional therapies have failed to significantly improve the long-term survival of patients for decades. Moreover, relapse of disease in patients with AML is a major issue and remains a difficult clinical challenge, with approximately 70% of patients relapsing within three years.

Development of targeted AML treatments is difficult due to the fact that the disease is highly heterogeneous, with more than 200 types of chromosome translocations and mutations having been identified in AML patients. Therapies targeting a single Tumor-Associated Antigen are therefore often insufficient to kill all of the cancer cell subsets in AML, leading to eventual disease relapse. To drive patients into deeper remissions and prevent relapses, therapies designed to target multiple AML antigens are needed. Additionally, recent studies suggest relapse is associated with the less targeted AML subpopulation of LSCs. Thus, the development of therapies targeting AML LSCs is sorely needed, but this has been challenging since LSC targets are often expressed on healthy cells, such as HSCs, leading to on-target, off-tumor treatment-induced toxicities.

CAR Cell Therapy for AML

The therapeutic administration of CAR cell therapies has considerably advanced the treatment of certain cancers, such as ALL. However, the successes of CAR cell therapies have not yet translated to successful treatment of AML, in part due to the absence of AML-specific target antigens. Due to their nonrestrictive expression, most AML antigens are also expressed on healthy HSCs or myeloid cells. Thus, on-target, off-tumor killing effects of the therapy may lead to the ablation of hematopoietic stem, progenitor or myeloid cells. While the B cell depletion that results from off-tumor killing of normal healthy cells in CAR-T therapy of ALL can be clinically managed, off-tumor killing of HSCs is unlikely to be tolerated in the case of AML treatment. Thus, the identification of antigens that enable more robust targeting of AML cells, including LSCs, along with new strategies to reduce off-target killing of HSCs, are critically needed to realize the promise of CAR cell therapies for AML treatment. These described challenges also extend to other potential AML therapeutic modalities, such as antibodies and bispecific T cell engagers.

256

SENTI-202 Approach to AML

SENTI-202 allogeneic CAR-NK cells are engineered with gene circuits that enable identification of cancerous versus healthy cells using NOT GATE + OR GATE logic decisions, and potentially improved persistence and more durable antitumor functions. SENTI-202 combines two different Logic Gates, and crIL-15 expression, as follows:

An iCAR NOT GATE gene circuit to prevent CAR-mediated killing of cells expressing either FLT3 or CD33 and a Safety Antigen, EMCN. The EMCN iCAR is intended to suppress CAR-NK cell cytotoxicity against healthy HSCs, reducing the risk of potential life-threatening bone marrow toxicity and potentially increasing the therapeutic window and on-target, on-tumor activity.

LOGO

An aCAR OR GATE gene circuit to activate CAR-mediated killing of AML cells expressing either or both of the Tumor-Associated Antigens FLT3 and CD33, thus increasing the targeting of both AML LSCs and blasts.

A crIL-15 gene circuit to simultaneously provide both autocrine and paracrine IL-15 signaling.

257

The following figure illustrates the design of SENTI-202 Logic Gating gene circuits to kill AML LSCs and blasts, while sparing healthy HSCs via (FLT3 OR CD33) NOT EMCN logic. Based on the medical community’s substantial clinical experience from autologous and allogeneic-bone marrow transplantations, we believe that protecting 10% to 20% of HSCs would be sufficient to enable hematopoietic recovery and provide clinical benefits to patients.

LOGO

We have established a proprietary Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform to identify complementary Tumor-Associated Antigens for the OR GATE and selective Safety Antigens for the NOT GATE. For SENTI-202, we applied this platform to discover the combination of the Tumor-Associated Antigens, FLT3 and CD33, and the corresponding Safety Antigen, EMCN, for application in AML.

258

In order to select the AML target antigens for the OR GATE gene circuit, we first established criteria for success, including: (i) expression on cell surface targetable by CAR, (ii) high expression across different AML subtypes, (iii) high expression in the critical LSC subset, (iv) little to no expression in non-hematopoietic tissues and (v) target combinations that yield broad coverage of AML LSCs and blast cells both among different patients and within individual patients. We utilized our Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform, which leverages an internal bioinformatics database comprising greater than 10 published studies and greater than 1,300 AML patient sample datasets. Using our proprietary transcriptomics- and proteomics-based bioinformatics pipeline, we identified FLT3 and CD33 as desirable Tumor-Associated Antigens for an OR GATE gene circuit to have the potential for comprehensive CAR-mediated killing of AML, including AML LSCs and blasts.

LOGO

As shown in the left panels of the two transcriptomic analysis figures below, our bioinformatics analyses concluded that FLT3 and CD33 are Tumor-Associated Antigens that are more highly expressed among AML LSCs and blast cells, respectively, relative to most healthy hematopoietic lineages.

As shown in the right panels of the two transcriptomic analysis figures below, these antigens are generally not expressed in normal healthy solid organ tissues. An important exception is that high-level expression of FLT3 is observed in healthy HSCs, as shown in the green box in the figure below, which is an observation consistent with published literature. In support of this observation, FLT3-directed bispecific antibodies and CAR-T have demonstrated bone marrow suppression in preclinical models previously described in literature. Accordingly, we believe preserving these HSCs through a NOT GATE is important to prevent bone marrow suppression during LSC-directed AML treatment.

259

LOGO

260

Further, our internal evaluations of primary AML samples also indicated that FLT3 and CD33 were highly expressed at the protein level, in both the AML blast and LSC subsets. A representative flow cytometric analysis is shown in the figure below. The green-shaded quadrants in the figure below represent AML cells that were either FLT3 positive, CD33 positive, or both, demonstrating that the OR GATE approach could limit the number of AML cells that are not targeted by our product candidate.

LOGO

SENTI-202 Preclinical Proof-of-Concept Data

Leveraging our DBTL Engine, we optimized the expression of the OR GATE FLT3 and CD33 CAR constructs, as shown above in the section titled “Our Platform: The Opportunity for Gene Circuits—Logic Gating—OR GATE”. We then evaluated the ability of these OR GATE CAR-NK cells to kill different leukemia cell lines, including ones that have differential expression levels of the FLT3 and CD33 antigens. As shown in the figure below, our FLT3 OR CD33 CAR-NK cells exhibited increased killing over that of the single-target CAR-NK cells, such as FLT3 only CAR-NK and CD33 only CAR-NK cells. Specifically, they demonstrated significantly improved killing across FLT3++ (p < 0.05) and CD33++ (p < 0.01) expressing leukemia cell lines in vitro, shown as FLT3++ and CD33++ bars in the figure below.

LOGO

261

We further confirmed in vitro that our OR GATE CAR-NK cells were capable of killing primary AML cells. As shown in the right panel in the figure below, we identified primary AML samples, labeled AML#770, #857, #847, #837 and #846, with expanded blast populations by flow cytometry, then performed co-culture in vitro cytotoxicity assays. Both of our versions of OR GATE CAR-NK cells, bivalent and bicistronic, showed significant cytotoxicity against the primary AML cells (p < 0.01) in comparison to unengineered NK controls.

LOGO

Furthermore, we evaluated the OR GATE CAR-NK cells in vivo in two AML xenotransplantation tumor models using MV4-11 and MOLM-13 AML cell lines. As shown in the figures below, in each of the mouse models, our FLT3 OR CD33 CAR-NK cells achieved statistically significantly greater anti-tumor activity compared to untreated control mice and mice treated with unengineered NK cells. Treatment with the OR GATE CAR-NK cells also improved survival compared to the control groups.

LOGO

262

LOGO

As shown in the figure below, using the same proprietary transcriptomics and proteomics-based bioinformatics methodology discussed earlier, we identified EMCN as a target antigen that is highly expressed on healthy HSCs but not on AML LSCs or blasts. This validates EMCN’s potential as a Safety Antigen to protect HSCs from potential on-target, off-tumor CAR-NK mediated toxicity. The rationale for utilizing EMCN as the Safety Antigen is further bolstered by a previous finding in the literature that identified EMCN as a marker of the key cell type for repopulating the blood and immune systems.

LOGO

263

Upon selection of EMCN as our primary Safety Antigen target, we have internally discovered and constructed multiple EMCN iCAR candidates, each comprised of an EMCN binder and a proprietary NOT GATE intracellular signaling domain. We then engineered NK cells with our lead FLT3 aCAR and these EMCN iCAR candidates to assess the EMCN iCARs’ ability to reduce in vitro cytotoxicity against a model healthy cell line that is engineered to be both FLT3+ and EMCN+. As shown in the figure below, we demonstrated, with multiple EMCN iCARs, that the NOT GATE conferred significant protection of EMCN-expressing cells from CAR-NK-mediated toxicity. The two different EMCN iCARs protected 50% to 67% of the EMCN+ cells from CAR-NK killing.

LOGO

We further evaluated the full SENTI-202 gene circuit-equipped NK cells in a model of donor-derived primary HSCs. Unlike the model Healthy Cell line shown above, bone marrow-derived CD34 enriched primary HSCs have natural levels of both the Tumor-Associated Antigens, FLT3 and CD33, as well as EMCN, expressed on the cell surface and represent a more realistic model to evaluate our proprietary AML NOT GATE gene circuit. As shown below, while SENTI-202 NK Cells, labeled as FLT3 OR CD33 NOT EMCN CAR-NK Cells, demonstrated killing of leukemia cell lines comparable to that of the control that does not express the EMCN iCAR, labeled as FLT3 OR CD33 CAR-NK Cells, our NOT GATE enabled significant protection of primary HSCs, exceeding the 10% to 20% protection target we anticipate would provide clinical benefits to patients.

Development Plan and Key Next Steps for SENTI-202

We have demonstrated, preclinically, the functionality of the key gene circuit components of SENTI-202, namely our FLT3 aCAR, CD33 aCAR and EMCN iCAR constructs. In 2022, we plan to present IND-enabling pharmacological data at key scientific conferences, seek feedback from the FDA through a pre-IND meeting, and apply for Orphan Drug Designation. In 2023, we plan to submit an IND application to support the clinical evaluation of SENTI-202.

National Cancer Institute (NCI) Contract to Support Development of SENTI-202

In September 2021, we were awarded funding from the National Cancer Institute of the National Institutes of Health in the form of a Small Business Innovation Research (SBIR) contract to support further development of SENTI-202 for AML towards clinical development. The Direct to Phase II SBIR contract will provide us with approximately $1.9 million in federal funding for the SENTI-202 program over two years.

SENTI-301 for the Potential Treatment of HCC

Overview

Our SENTI-301 product candidate is a Multi-Armed allogeneic CAR-NK cell therapy that we are developing for the treatment of HCC. We are engineering NK cells to target GPC3, which is highly expressed in 70% to 90% of HCCs and has low or no expression on normal adult tissues. SENTI-301 is armed with a combination of immuno-stimulatory payloads, including our proprietary crIL-15 gene circuit, intended to promote expansion and persistence of our CAR-NK cells, as well as activation and recruitment of endogenous immune cells into the solid tumor microenvironment for enhanced anti-tumor activity. The expression of one of these potent payloads, interleukin-12, from SENTI-301 may be modulated via a small molecule Regulator Dial or in response to CAR activity via a Smart Sensor such as a CAR-activated synthetic promoter.

LOGO

Hepatocellular Carcinoma: an Unmet Medical Need

HCC accounts for approximately 90% of primary liver cancers and represents a large unmet medical need due to the lack of effective treatment options. Globally, it is the sixth most commonly diagnosed cancer, and the fourth leading cause of cancer deaths. In the United States, the rate of death from liver cancer increased by 43% from 7.2 to 10.3 deaths per 100,000 people between 2000 and 2016. Frequently, HCC develops in patients with liver disease such as hepatitis C virus, alcoholic liver disease or non-alcoholic steatohepatitis.

Available therapies are only modestly efficacious and HCC mortality rate remains high despite recent improvements in treatment options. The most effective therapy currently available is atezolizumab plus bevacizumab combination therapy for first line treatment with a 27.3% objective response rate and a 5.5% complete response rate. Nivolumab plus ipilimumab combination therapy is the most effective second-line treatment currently available with a 15% to 16% objective response rate and a 1% to 2% complete response rate.

266

SENTI-301 Approach to HCC

As shown in the figure below, SENTI-301 allogeneic NK cells are engineered with multiple anti-tumor activities to achieve a Multi-Armed attack on solid tumors. Specifically, SENTI-301 includes a CAR that targets GPC3 and secretion of (i) crIL-15 for autocrine signaling to potentially promote CAR-NK cell proliferation, persistence, effector functions and paracrine signaling of surrounding immune cells and (ii) IL-12 to activate and recruit endogenous immune cells in the tumor microenvironment in order to induce a potent immune response.

LOGO

GPC3 is a Tumor-Associated Antigen expressed in approximately 70% to 90% of human HCCs, but not expressed in healthy liver tissue or other human organs after birth. GPC3 has previously been clinically evaluated as a therapeutic target for immunotherapy in HCC. GPC3 is also a histologic and serum clinical marker for HCC and its expression has been associated with poor prognosis. Functionally, GPC3 is associated with the control of cell division and growth regulation. We built GPC3 CAR constructs to redirect NK-mediated cytotoxicity against HCC using a GPC3 binder that associates to the membrane proximal region of the GPC3 protein.

As recombinant proteins, the IL-15 and IL-12 pleiotropic cytokines have previously demonstrated anti-tumor efficacy in several preclinical studies. IL-15 has been shown to improve NK cell persistence in vivo and maintain cytotoxicity. Functionally, IL-12 promotes the secretion of Th1 cytokines from other immune cells, potentiating the recruitment and activation of the endogenous innate and adaptive immune systems, which leads to subsequent induction of an anti-tumor immune response.

Our crIL-15 gene circuit is designed to simultaneously produce both membrane-associated and fully secreted IL-15 to support both autocrine- and paracrine-like signaling. As described above, our crIL-15 gene circuit functionally improved CAR-NK effector functions in serial killing assays in vitro when compared to wild-type fully secreted IL-15 alone. We believe that the ability of crIL-15 to also secrete active IL-15 into the tumor microenvironment should enable stimulation of endogenous immune cells within the tumor microenvironment in solid tumor settings.

Previous clinical experiences with adoptive cell transfer of engineered immune cells expressing IL-12 have demonstrated the feasibility of IL-12-secreting cell therapies. However, systemic immunotoxicity has been observed in patients when IL-12 is expressed without tight regulation from adoptive cell therapies. Thus, the narrow therapeutic window associated with IL-12 has limited its success to date.

We believe our gene circuit technologies may address these previously observed therapeutic window limitations from clinical studies. One potential approach is to modulate the expression of IL-12 using our

267

Regulator Dial gene circuit. For example, a NS3-based Regulator Dial can be utilized to modulate IL-12 expression in vivo after infusion of the SENTI-301 product candidate via FDA-approved, orally dosed NS3 inhibitors. The NS3 Regulator Dial consists of a synthetic drug-regulated transcription factor and a synthetic promoter responsive to this regulated transcription factor. In the absence of the drug, the transcription factor is inactive, and no therapeutic protein (such as IL-12) is produced from the engineered cells. In the presence of the drug, the transcription factor is activated, leading to production of the IL-12 payload.

A potential clinical application of the NS3-based Regulator Dial is illustrated in the figure below. Upon infusion of SENTI-301, the IL-12 regulated gene circuit remains in the off state, thus limiting the potential of systemic immunotoxicity in patients. As infused CAR-NK cells survey the body, we expect local enrichment, activation and expansion of SENTI-301 in GPC3-positive tumors. The antigen-driven anti-tumor response is further supported by the expression of crIL-15. Once local infiltration and engraftment of SENTI-301 is established, NS3 inhibitors may be given to patients in order to induce IL-12 expression and promote recruitment of endogenous immune cells to help further mount an anti-tumor response. By incorporating multiple therapeutic mechanisms, such as GPC3 CAR, crIL-15 and regulated IL-12, into the allogeneic NK cells, we believe our SENTI-301 product candidate would be armed with the necessary tools to activate multiple pathways in the tumor-immunity cycle in complementary ways in order to combat HCC and its hostile tumor microenvironment.

SENTI-301 Supporting Data

GPC3 CAR Expression and Function

We have designed and built hundreds of GPC3 CAR constructs, with the aim to identify and select our lead GPC3 CAR construct based on its expression profile and cytotoxic functions. These GPC3 CAR constructs were delivered into NK cells and evaluated. Anti-tumor cytotoxic functions were evaluated in co-culture assays against the HCC cell lines, HepG2 and HuH7. The figure below shows a representative experiment demonstrating that NK cells engineered to express a GPC3 CAR and crIL-15, shown below in teal, have significantly higher killing activity against HCC target cells (GPC3-positive) compared to unengineered NK cells in an Incucyte assay.

LOGO

IL-15 expression

We have constructed and evaluated multiple crIL-15 gene circuits. The figure below shows a representative experiment demonstrating robust simultaneous expression of both membrane-associated IL-15 on the cell surface and fully secreted IL-15 from engineered NK cells.

LOGO

Regulated IL-12 expression

The gene circuit embedded in the SENTI-301 product candidate is designed to enable regulated IL-12 production. For example, we are optimizing the Regulator Dial gene circuit in immune cells to minimize basal

269

expression, resulting in minimal production of IL-12 in the absence of NS3 inhibitors, while maintaining high induced expression in a drug-dose dependent manner. As shown in the figure below, NK cells engineered with the IL-12 regulated gene circuit were evaluated for induction of IL-12 expression in the presence of the small molecule NS3 inhibitor, grazoprevir, or GRZ, over a range of small molecule concentrations. The basal IL-12 expression was low at ~3 pg/mL. Peak induction was achieved at ~0.1 µM of GRZ, where production of IL-12 was increased by greater than 100-fold relative to the basal level. Importantly, IL-12 production was observed at concentrations as low as 0.01 µM of GRZ, well below the known drug Cmax in humans of 0.23 µM.

LOGO

This Regulator Dial gene circuit for IL-12 was evaluated in vivo. As shown in the figure below, immune-deficient NSG mice were dosed with 37.5 mg/kg of GRZ on day 0 and subsequently 75 mg/kg GRZ from day 1 through day 4. These mice received 20×10⁶ engineered cells on day 2. Blood samples were drawn on day 4 and day 8 to assess IL-12 levels during the small molecule-induced state and post-small molecule withdrawal, respectively. We found that on day 4, IL-12 was detected at 1,642 pg/mL in the plasma of mice that received GRZ versus 19 pg/mL in vehicle-treated mice (p < 0.01), a greater than 80-fold upregulation of IL-12 production. On day 8, 4 days after the final GRZ dose, both the GRZ- and vehicle-treated mice exhibited only background levels (20 – 30 pg/mL) of IL-12, demonstrating that IL-12 production was switched off in the absence of GRZ.

LOGO

IL-12 can be encoded as secreted IL-12 or crIL-12. Using our calibrated release technology platform, we have created crIL-12 versions of the IL-12 cytokine for the SENTI-301 product candidate. We observed in in

270

vitro studies that the crIL-12 versions of IL-12 retained IL-12 biological function. In vitro, our lead candidates using crIL-12 demonstrated low IL-12 basal levels in the absence of GRZ (<100 pg/1e6 cells in 24 hours), while induction with 10nM of GRZ led to an increased IL-12 expression by ~390-fold (30,000 pg/1e6 cells<0.0001) in 24 hours. We validated the Regulator Dial gene circuit in vivo, and observed ~150-fold change in IL-12 secretion (154.8 pg/mL - p= 0.02) in mice 48 hours after GRZ treatment (50 mg/kg).

Development Plan and Key Next Steps for SENTI-301

We have demonstrated, preclinically, the key gene circuit components of SENTI-301, namely our GPC3 aCAR, our engineered crIL-15 and IL-12 constructs, and our NS3-based Regulator Dial constructs. In 2022, we plan to present IND-enabling pharmacological data at key scientific conferences, seek feedback from the FDA through a pre-IND meeting, and apply for Orphan Drug Designation.

SENTI-401 for the Potential Treatment of CRC

Overview

Our SENTI-401 product candidate is a Logic Gated allogeneic CAR-NK cell therapy that we are developing to more precisely target and eliminate CRC cells while sparing healthy cells elsewhere in the body. We are engineering NK cells to express a CAR directed against CEA, which is highly overexpressed in 85% to 90% of colorectal cancer samples but is also expressed in epithelial cells in healthy tissues. The expression profile of CEA in both tumor and healthy cells has resulted in on-target, off-tumor toxicities by conventional CEA-targeted therapies, thus limiting their clinical success. To address this challenge, we are engineering NK cells with a NOT GATE implemented via an iCAR targeted against an epithelial cell Safety Antigen called VSIG2. Thus, the SENTI-401 product candidate’s logic gating is intended to more effectively treat CRC patients by targeting a well-known Tumor-Associated Antigen, CEA, and widen the therapeutic window by preventing killing when CEA appears on healthy cells that also express the VSIG2 Safety Antigen. Further, SENTI-401 is being engineered to express our proprietary crIL-15 effector to promote persistence and more durable antitumor functions.

Colorectal Cancer: an Unmet Medical Need

CRC accounts for approximately 10% of all annually diagnosed cancers and cancer-related deaths worldwide and is the second and third most commonly diagnosed cancer in women and men, respectively. The

271

incidence of CRC worldwide is predicted to increase to 2.5 million new cases in 2035. Of new colorectal cancer diagnoses, 20% of patients present with metastatic disease and another 25% who present with localized disease will later develop metastases. Among patients with metastatic colorectal cancer, approximately 70% to 75% of patients survive after one year of their initial diagnosis; however, the five-year survival rate is less than 20% despite multiple lines of treatment, including combinations of chemotherapy and targeted therapies.

SENTI-401 Approach to CRC

CEA is a tumor-associated protein overexpressed in many epithelial cancers, most notably in colorectal cancer. However, it is also expressed in a variety of normal epithelial cells throughout the gastrointestinal tract. As shown in the figure below, bioinformatics analyses of RNA sequencing data collected from over 9,500 tumor and 8,500 healthy tissue samples showed that CEACAM5, one of the main isoforms of CEA, is overexpressed across many cancer types, especially colorectal cancer. CEACAM5 expression is also found in healthy organs, including tissues in the GI tract and lungs. Cancer immunotherapies using vaccines and antibodies targeting CEA are actively being investigated in the clinical setting. However, recent clinical studies have shown dose-limiting on-target, off-tumor toxicities in these healthy tissues that also express CEA.

LOGO

We are developing our SENTI-401 product candidate to overcome the challenges associated with targeting the CEA Tumor-Associated Antigen that is present on both tumor and healthy cells. To mitigate the potential risk of on-target, off-tumor toxicity, we are designing SENTI-401 with a NOT GATE gene circuit to differentiate between cancerous and healthy cells. Specifically, SENTI-401 incorporates the following gene circuit:

An iCAR with a NOT GATE gene circuit that restricts CAR-mediated cell killing to CRC cells that express CEA but not healthy cells that express an epithelial cell Safety Antigen, VSIG2. This NOT gate is designed to potentially reduce on-target, off-tumor toxicity, thus potentially enabling more effective treatment of CEA-expressing cancers.

An aCAR that targets CEA, a well-characterized antigen that is overexpressed in many cancers, including CRC.

A crIL-15 gene circuit to simultaneously provide both autocrine and paracrine-like IL-15 signaling.

272

SENTI-401 Supporting Data

Our CEA aCAR-NK cells kill CRC cells in an antigen-dependent manner

We have designed, built and evaluated hundreds of CEA aCAR constructs by varying the antigen binders, co-stimulatory domains, and other parameters. We screened these CEA aCAR constructs for robust and durable expression on NK cells, and cytotoxicity against CEA-positive tumor cell lines. As shown in the figure below, we evaluated our CEA aCAR-transduced NK cells, labeled as CEA aCAR #1 and CEA aCAR #2, for anti-tumor cytotoxic functions against a CEA-positive CRC tumor cell line, Ls174t. Both of these CEA aCAR constructs, in comparison to unengineered NK cells or NK cells engineered with a non-specific aCAR construct, mediated statistically significant cytotoxicity against Ls174t and released cytokines in an antigen-specific manner.

Our CEA aCAR-NK cells significantly reduced tumor burden in a human CRC xenograft tumor model in vivo

To assess the in vivo activity of our CAR-NK cells, we developed human xenograft mouse models of CEA-positive CRC tumors. We implanted Ls174t CRC cells in the peritoneal cavity of NSG mice and measured tumor burden and disease progression using a bioluminescent reporter. Mice were treated with PBS, or with one single dose of unengineered NK cells or CEA aCAR-NK cells. CEA aCAR-NK cells resulted in significant reduction (p < 0.05) in tumor burden in mice compared to control mice treated with unengineered NK cells, as shown in the figure below.

Utilization of the VISG2 protein as our NOT GATE gene circuit Safety Antigen

We have developed a robust Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform for the development of NOT GATE CAR-NK therapies. Using this approach, we have identified genes that are differentially expressed in healthy versus tumor tissues and selected antigen candidates based on-target expression in tissues, subcellular localization, antigen topology or presence of extracellular domains and antibody availability. To protect healthy epithelial cells that also express CEA, we discovered VSIG2 as a Safety Antigen candidate. VSIG2 exhibits a favorable pattern of expression in the membrane of epithelial cells of the gastrointestinal tract and lungs, which are CEA-positive tissues that are most at risk of on-target, off-tumor toxicity. We further validated the expression of VSIG2 using immunohistochemistry, or IHC, in healthy tissues and confirmed the lack of expression in primary CRC tumor tissue samples. Specifically, IHC analyses of colorectal tumor tissues and healthy colon epithelium demonstrated that CEA is expressed in both healthy samples, as shown in the upper left of the figure below, and tumor samples, as shown in the lower left of the figure below. In addition, the Safety Antigen VSIG2 is only expressed in healthy colon epithelium, as shown in the upper right of the figure below, and not in tumor samples, as shown in the lower right of the figure below.

LOGO

275

Leveraging these findings, we have constructed VISG2-iCARs that showed selective NOT gate functions in vitro. As shown in the figure below, we engineered NK cells to express both our CEA-aCAR and two different VSIG2-iCARs, each with a different intracellular inhibitory domain, at greater than 70% efficiency. These NOT gated CAR NK cells showed equivalent tumor killing relative to CEA aCAR only control NK cells, but were observed to significantly reduce cytotoxicity against a Model Healthy cell line, labelled CEACAM5+VSIG2+ below, by up to 43%.

LOGO

Development Plan and Key Next Steps for SENTI-401

In 2022, we intend to further evaluate different variants of the CEA aCAR and VSIG2 iCAR constructs, for example different aCAR co-stimulatory domains and iCAR inhibitory domains etc., in vitro and in vivo to determine the exact final coding sequences of these individual components. These finalized key gene circuit components would then be incorporated into an optimized vector backbone for cGMP manufacturing. Concurrent with anticipated cGMP manufacturing activities in 2022 and 2023, we anticipate that IND-enabling pharmacology and toxicology studies will be executed to support future submission of an IND application.

Our Gene Circuit Application to Allogeneic, NK Cells for Oncology

•

Innate Killing: NK cells naturally carry multiple activating and inhibitory receptors that enable them to innately kill tumor cells while sparing healthy tissues. Furthermore, NK cells have been engineered with CARs to enhance their targeted killing activity. We leverage these features to create Logic Gated CAR-NKs, such as OR GATE CAR-NKs that enhance the killing of heterogeneous tumors and NOT GATE CAR-NKs that spare healthy cells from undesired toxicity and thereby potentially improve on-target, on-tumor killing.

•

Immune Activation: NK cells have been shown to support robust activation of anti-tumor immune pathways via proinflammatory cytokine and chemokine secretion. We leverage this feature with our Multi- Arming gene circuits to further improve their ability to trigger endogenous, complementary anti-tumor activity by engaging the rest of the tumor immunity cycle.

276

•

Validated Clinical Activity and Tolerability: Allogeneic, as in healthy donor-derived, CAR-NK cells have been recently shown in the clinical setting to have the potential to promote anti-tumor activity along with low risks of graft versus host disease, or GvHD, severe cytokine release syndrome, or CRS, and neurotoxicity.

•

Broad Patient Access: We have established proprietary protocols to derive NK cells from healthy donors, manufacture them at scale with a projected low cost and cryopreserve them with high retained viability post-thaw. As a result, we believe that CAR-NK cells have the potential to be broadly accessible to patients as they may be delivered rapidly to patients in an off-the-shelf manner and in outpatient settings.

Portfolio Expansion Opportunities

Our Discovery Stage Programs

We believe our gene circuits can be readily adapted to new disease contexts to enable a variety of additional CAR-NK product candidates that address important cancers. As shown in the figure below, our SENTI-411 and SENTI-421 product candidates are Logic Gated CAR-NKs that leverage the same NOT GATE gene circuit technology deployed in SENTI-202 and SENTI-401. We are developing these product candidates for precise targeting of solid tumors expressing certain Tumor-Associated Antigens, while protecting against on-target, off-tumor toxicity toward healthy cells in order to widen the therapeutic window. Additionally, our SENTI-311 product candidate is a CAR-NK that utilizes our Multi-Arming gene circuit technology currently deployed in our SENTI-301 product candidate. SENTI-311 is being developed for the treatment of solid tumors, where Multi-Arming is designed to overcome disease evasion. Beyond SENTI-411, SENTI-421 and SENTI-311, we envision advancing multiple additional CAR-NK programs equipped with our gene circuits towards IND submissions. Starting in 2024, we anticipate submitting approximately one IND application per year.

LOGO

Furthermore, we are actively pursuing the nomination and development of multiple product candidates that harness the full breadth of our gene circuit platform beyond Logic Gating and Multi-Arming of allogeneic CAR-NK cells within oncology. Our additional discovery efforts are focused on a diverse set of cell and gene therapy applications outside of oncology. In particular, we have entered into collaborations with Spark Therapeutics, Inc. (acquired by Roche Holding AG) for the design of Smart Sensors for disease- and tissue-specific gene therapy, and with Bluerock Therapeutics, Inc. (acquired by Bayer AG) for the use of Smart Sensors and Regulator Dials for regenerative medicines.

277

Our current discovery stage programs are as follows:

LOGO

We believe our gene circuit platform technologies can be broadly leveraged to address additional clinical indications. For example, there are additional opportunities for the application of the NOT GATE gene circuit toward other solid and/or liquid tumor indications beyond SENTI-401, SENTI-411 and SENTI-421. Toward that end, we have developed a Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform to identify future opportunities.

278

Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform

We have developed a proprietary Tumor-Associated Antigen and Safety Antigen Paired Discovery Platform to select and validate NOT GATE antigen candidates, as shown in the figure below. We have built a generalizable bioinformatics pipeline that uses RNA transcriptomics data to discover and prioritize tumor and healthy tissue Safety Antigens. We identify Tumor-Associated Antigens that are highly expressed in cancer cells with as little healthy tissue expression as possible, for example Tumor-Associated Antigen A in the figure below. We then discover healthy tissue selective Safety Antigens, for example Safety Antigen E in the figure below, that can protect those healthy tissues that express the Tumor-Associated Antigens, for example Tissues 2 and 5 in the figure below. This process looks at differences in Safety Antigen gene expression in healthy versus tumor tissue. Leads are selected based on the co-expression of Tumor-Associated Antigens and Safety Antigens in healthy tissues, the localization of the Safety Antigens to the cell surface, Safety Antigen topology (presence of extracellular domain) and Safety Antigen-specific antibody availability. Prioritized Tumor-Associated Antigen and Safety Antigen pairs are further validated in primary cancer and primary healthy tissue samples. We leveraged this platform to identify the Safety Antigen targets for the SENTI-202 and SENTI-401 programs, thus demonstrating our ability to target both liquid and solid tumors. This approach allows us to potentially expand our NOT GATE approach to additional cancer indications in which existing single-target approaches, such as monoclonal antibodies, antibody-drug conjugates and single-target CAR cells, are inadequate due to a lack of specificity for cancer cells.

Portfolio Expansion Opportunities Outside of Oncology

Our additional discovery efforts are focused on cell and gene therapy applications that utilize other facets of our synthetic biology platform, including Smart Sensors and Regulator Dials in therapeutic areas beyond oncology.

Manufacturing

279

patient’s own cells, is the ability to manufacture large batches of drug product from healthy donor cells that can be produced in advance of clinical use, and then stored in frozen vials. Upon commercialization, we expect to be able to make our cell therapies, if approved, broadly accessible in an off-the-shelf manner to cancer patients.

Our experienced manufacturing and process development team has established an innovative process for efficient production of our allogeneic CAR-NK cell product candidates. Critical aspects of the cell manufacturing process include the ability to perform four key steps in the CAR-NK cell manufacturing process:

LOGO

Step 1: Source, Isolate and Bank Purified NK Cells as Starting Cells.

Starting Cells are obtained from enriching and isolating NK cells from qualified healthy donors. Purified NK cells are subsequently cryopreserved and characterized for consistent performance, including assays for cell phenotype, transduction efficiency, cell expansion capability and anti-tumor cytotoxicity. For our initial SENTI-301 and SENTI-202 product candidates, we plan to derive Starting Cells from leukapheresis products collected from qualified healthy donors. From each leukapheresis collection, we will isolate and cryopreserve hundreds of millions of Starting Cells to support multiple product production batches. We believe that peripheral blood derived leukapheresis products are an attractive starting material source due to (i) a mature and validated commercial supply chain, (ii) the large number of purified NK cells per collection and (iii) our ability to characterize the NK cells prior to initiation of manufacturing. An analysis of over a dozen recent isolations performed from different healthy donors demonstrated that our process achieved greater than 95% NK cell purity, greater than 90% viability and up to 500 million NK cells per collection, as shown in the figure below:

LOGO

Step 2: Genetically Engineer Starting Cells with Gene Circuits.

280

We genetically modify our NK cells through a viral vector transduction process focused on enhancing gene circuit expression while minimizing impacts on compromising cell viability or cell expansion. To generate our CAR-NK products, the Starting Cells are first thawed and activated. On a specific day post activation, the activated cells undergo our vector transduction process to genetically incorporate our gene circuits. The figure below shows transduction of our activated Starting Cells successfully reached approximately 50% transduction efficiency using a potentially clinically appropriate manufacturing process. Gene circuit-enabled CAR-NK cells were expanded over a total of 21 days. As shown in the center panel of the figure below, our transduction process was shown to have minimal impact on the cell expansion capability when comparing transduced CAR-NK cells versus unengineered NK cells. The transduced cells retained >90% viability with similar growth rate to unengineered NK cells through the 21st day.

LOGO

Step 3: Expand and Scale CAR-NK Cells.

Our expansion process is designed to generate large numbers of final product doses per manufacturing batch. This production process has resulted in high purity of NK cells (>98%) with minimal (<1%) detectable residual T cells. As shown in the figure below, our current process has produced greater than 6,000-fold expansion of CAR-NK cells in a 21 day process, achieving a planned clinical manufacturing scale of hundreds of patient doses per a single manufacturing batch. We are developing additional technologies and processes to further enhance NK cell expansion for commercial manufacturing, including alternative methods for cell activation and expansion and utilization of large-scale cell culture systems.

LOGO

Step 4: Formulate and Cryopreserve CAR-NK Cells.

For freezing and distribution, we intend to formulate and cryopreserve our final product to retain viability, persistence and cytotoxic function post-thaw for off-the-shelf use. Each batch of CAR-NK cells will be filled into vials and cryopreserved for long term storage. The CAR-NK cell product candidates will be shipped in vials to clinical sites, where they will be thawed and infused on demand. We have demonstrated that cryopreserved

281

CAR-NK cells can retain key functional properties required for cancer treatment, including stable transgene expression >44 days. As shown below, our cryopreserved CAR-NK cells retained viability and anti-tumor functions in both in vitro and in vivo models of AML:

Technical Expertise and Facilities for Clinical and Commercial Manufacturing

Our corporate headquarters is located in South San Francisco, CA, where we lease approximately 40,000 square feet of research and development and corporate office space. In this location, we have approximately 10,000 square feet dedicated to manufacturing development labs. We have established research and development teams with extensive experience in cell and gene therapy manufacturing operations, including vector process development, cell process development, analytical development, quality control and quality assurance. In June 2021, we signed a lease agreement for a property in Alameda, California with approximately 92,000 square feet and have begun construction on a state-of-the-art cGMP facility to support clinical and commercial-scale manufacturing of multiple allogeneic CAR-NK cell product candidates. This manufacturing facility is being designed as a customized end-to-end manufacturing solution to give us the ability to isolate NK cells, engineer these cells with proprietary gene circuits, perform cell culture expansion in large batches, and cryopreserve and store the final cGMP products.

We expect to complete the first stage of construction for our cGMP facility and present on our clinical-scale GMP manufacturing process for gene-circuit-engineered NK cells at key technical conferences in 2022.

Our allogeneic production process and proprietary manufacturing capabilities are central to our business strategy of maintaining control over the quality and supply of our present and future candidates for allogeneic CAR-NK cell therapies. In addition, we believe that our proprietary manufacturing process enables an anticipated cost in line with competitive allogeneic production process estimates. Continued advancements in cell culture scale and process efficiencies may further reduce this cost over time.

In addition, we may also leverage our manufacturing facility to expand the application of our gene circuit technology to biomanufacturing in partnership with one or more third parties. See the section titled “Potential Collaboration Around Gene Circuits and GMP Manufacturing.”

Research Collaboration and License Agreement with Spark Therapeutics, Inc.

In April 2021, we entered into a Research Collaboration and License Agreement, or the Spark Agreement, with Spark Therapeutics, Inc., or Spark. Under the Spark Agreement, we engaged in a collaborative research program with Spark to design, build and test synthetic promoters that are intended to have each one of five sets of desired characteristics, or promoter profiles. Spark is obligated to reimburse us for our costs and expenses incurred in connection with the conduct of the research program. Upon completion of work under the research program for a particular promoter profile, Spark may select up to a specified number of synthetic promoters for such promoter profile on which it can conduct in vitro and in vivo evaluation activities.

We granted option rights to Spark, on a promoter profile-by-promoter profile basis, to obtain an exclusive, royalty-bearing, sublicensable, worldwide license under our intellectual property rights to develop, manufacture, commercialize and otherwise exploit, for the cure, treatment, palliation, prevention or diagnosis of specified indications, or a licensed field, in vivo gene therapy products incorporating an applicable synthetic promoter that is developed under the Spark Agreement with respect to such promoter profile and is directed towards specified cell types in the central nervous system, eye, or liver. Spark may exercise its option for a single synthetic promoter per promoter profile together with certain related synthetic promoters, or licensed promoters, prior to the expiration of the applicable evaluation period. During the research program and until the expiration of the evaluation period for each promoter profile, we are obligated to work exclusively with Spark on the development, manufacture and commercialization of in vivo gene therapy products incorporating synthetic promoters intended to have the same cell type specificity as such promoter profile.

After exercise of an option, Spark will be responsible for all development, manufacture, commercialization and exploitation in the licensed field, at its own cost and expense, of all in vivo gene therapy products containing an applicable licensed promoter, and we will retain the right to develop, manufacture, commercialize and exploit other products that incorporate the licensed promoters as well as in vivo gene therapy products that incorporate the licensed promoters for uses outside the licensed field. If Spark does not exercise an option for a particular promoter profile prior to the expiration of the evaluation period for such promoter profile, we will retain all rights to the synthetic promoters developed under the Spark Agreement without any further obligations to Spark for such promoter profile.

Pursuant to the Spark Agreement, we received an upfront payment from Spark of $3 million. If Spark exercises an option for a particular promoter profile, it will be required to pay us an option exercise fee in the low to mid- single digit millions. For each licensed promoter-containing in vivo gene therapy product, or licensed product, developed and commercialized by Spark or its affiliates or sublicensees, we are eligible to receive development, regulatory and commercialization milestone payments from Spark up to an aggregate dollar amount in the mid teens millions, and sales milestone payments from Spark up to an aggregate dollar amount in the low hundred millions. In total, we are potentially eligible to receive upfront, opt-in and milestone payments exceeding $645 million if Spark exercises its options for all five promoter profiles and Spark, its affiliates and its sublicensees successfully develop and commercialize five licensed products; we will be eligible to receive additional milestone payments if additional licensed products are developed and commercialized by Spark, its affiliates and its sublicensees. Further, Spark will be obligated to pay us royalties in the low-single digits percentage on net sales of each licensed product sold by Spark, its affiliates and its sublicensees, subject to specified reductions and offsets. Spark’s obligation to pay royalties to us will expire for each licensed product when certain licensed patents and regulatory exclusivities have expired in the country of sale and a minimum number of years has elapsed since the first commercial sale of such licensed product in such country.

286

The Spark Agreement will expire at the end of the last evaluation period if Spark does not exercise any of its options. If Spark exercises at least one option, then the Spark Agreement will expire, on a licensed product-by-licensed product and country-by-country basis, upon the expiration of Spark’s royalty obligation for such licensed product in such country. Spark may terminate the Spark Agreement in its entirety, or on a promoter profile-by-promoter profile or licensed promoter-by-licensed promoter basis, following a specified notice period. Either party may terminate the Spark Agreement in its entirety or in part if the other party fails to cure its material breach of the Spark Agreement within a specified cure period, or immediately if the other party becomes bankrupt or insolvent. We may terminate the Spark Agreement if Spark or any of its affiliates commences any action challenging the validity or enforceability of the licensed patents, other than in certain specified circumstances, or if Spark’s sublicensee challenges our licensed patents, under certain specified circumstances.

Collaboration and Option Agreement with BlueRock Therapeutics LP

In May 2021, we entered into a Collaboration and Option Agreement, or the BlueRock Agreement, with BlueRock Therapeutics LP, or BlueRock. BlueRock is a wholly-owned subsidiary of Bayer Healthcare LLC. Bayer Healthcare LLC’s parent company is Bayer AG, which served as the lead investor in our Series B financing through its Leaps by Bayer unit. Under the BlueRock Agreement, we have engaged in three collaboration programs with BlueRock to research and develop gene circuits that have specified functions. We are responsible for up to $10 million in costs and expenses incurred in connection with our conduct of research activities under an agreed-upon research plan. If the parties mutually agree to add new research activities to the research plan, then BlueRock will be obligated to reimburse us for the costs and expenses that we incur in connection with the agreed-upon additional research activities that, together with costs and expenses incurred under the initial research plan, exceed $10 million. We have not yet received any payment from BlueRock under the BlueRock Agreement and we do not have any obligations to make any payments to BlueRock under the BlueRock Agreement. We are obligated to use commercially reasonable efforts to conduct the research activities assigned to us under the research plan. If we materially breach that obligation and do not cure it within a specified period, BlueRock will have the right to receive a transfer of technology and perform the remainder of the research plan at its own expense.

Upon completion of work under a research plan for a collaboration program, the joint steering committee established by the parties will identify, subject to a specified maximum, a number of gene circuits per collaboration program, or option gene circuits, that have been successfully developed under such collaboration program. We have granted to BlueRock an option, on a collaboration program-by-collaboration program basis, to obtain an exclusive or non-exclusive license under our intellectual property rights to develop, manufacture and commercialize, for the prevention, treatment or palliation of specified indications, or a licensed field, cell therapy products that contain cells of specified types that incorporate an option gene circuit from such collaboration program or a closely related derivative gene circuit. For each collaboration program, BlueRock may conduct evaluation activities on the option gene circuits from such collaboration program to determine whether to exercise its option, and BlueRock may exercise its option to such option gene circuits together with certain closely related derivative gene circuits, or licensed gene circuits, prior to the expiration of a certain time period, or the option exercise period, which includes a minimum amount of time after the expiration of the three-year research term, delivery of a data package to BlueRock, and completion of a transfer of technology to enable BlueRock’s evaluation activities, whichever happens last. If BlueRock exercises its option for a collaboration program, the parties shall negotiate the financial terms, which will be within certain pre-agreed parameters and may be determined by baseball arbitration if the parties do not reach agreement within the specified negotiation period, and enter into an otherwise agreed-upon written license agreement, or a commercial license. If the parties enter into a commercial license, BlueRock will be responsible, at its sole expense, for the development, manufacture and commercialization, in the applicable licensed field, of cell therapy products containing cells of an applicable type that incorporate an applicable licensed gene circuit, and we will be eligible to receive from BlueRock development, regulatory and commercialization milestone payments, in amounts to be agreed-upon before entry into the commercial license, and royalties, subject to negotiation, equal to low single digit percentages of net sales of applicable cell therapy products sold by BlueRock, its affiliates and its sublicensees,

287

subject to specified reductions and offsets. If BlueRock does not exercise its option for a collaboration program prior to the expiration of the applicable option exercise period, then we will retain all rights to the gene circuits developed under such collaboration program without any further obligations to BlueRock.

For each collaboration program, we are obligated to work exclusively with BlueRock on the development, manufacture and commercialization, in the applicable licensed field, of cell therapy products that contain cells of specified types that incorporate the specific type of gene circuit for such collaboration program. The end date for this exclusivity obligation for each collaboration program will depend upon whether BlueRock exercises its option for such collaboration program and, if it does, whether the parties enter into a commercial license for such collaboration program. If BlueRock does not exercise its option, then it will end on the expiration of the applicable option exercise period. If BlueRock exercises its option but the parties do not enter into a commercial license, then it will end after a specified time following expiration of the applicable negotiation or baseball arbitration period for the commercial license. If BlueRock exercises its option and the parties enter into a commercial license, then it will end a certain amount of time after the later of completion of research activities or execution of the commercial license.

In addition to the option described above, we granted a right of first negotiation to BlueRock, on a collaboration program-by-collaboration program basis, to obtain a license under our intellectual property rights to research, develop, manufacture and commercialize, for the prevention, treatment or palliation of a specified disease area, or the negotiation field, cell therapy products containing cells of a specified type, or the negotiation cells, that incorporate an applicable efficacy gene circuit developed under such collaboration program. This right of first negotiation does not overlap with the option described above because it pertains to different combinations of indications, cell types and gene circuits. Starting from the effective date of the BlueRock Agreement and, on a collaboration program-by-collaboration program basis, continuing for twelve months or, if later, until the completion of a certain portion of the research plan for such collaboration program, we are obligated to work exclusively with BlueRock on the development, manufacture and commercialization, in the negotiation field, of cell therapy products containing negotiation cells that incorporate the specific type of gene circuit for such collaboration program.

The BlueRock Agreement will expire, on a collaboration program-by-collaboration program basis, upon the earliest of the expiration of the option exercise period for such collaboration program, the effective date of the commercial license, the expiration of the applicable negotiation or baseball arbitration period for the commercial license, or the date the parties mutually agree to cease negotiations for the commercial license. Such expiration shall occur no later than January 2026 unless the parties mutually agree to extend the research term. BlueRock may terminate the BlueRock Agreement in its entirety, or on a collaboration program-by-collaboration program basis, following a specified notice period. Either party may terminate the BlueRock Agreement if the other party fails to cure its material breach of the BlueRock Agreement within a specified cure period, or immediately if the other party becomes bankrupt or insolvent. We may terminate the BlueRock Agreement if BlueRock or any of its affiliates commences any action challenging the validity or enforceability of our patents, other than in certain specified circumstances, or if BlueRock’s sublicensee challenges our patents under certain specified circumstances.

Other Agreements

National Cancer Institute (NCI) Contract to Support Development of SENTI-202 in Acute Myeloid Leukemia

In September 2021, we were awarded funding from the National Cancer Institute in the form of a Small Business Innovation Research (SBIR) contract to support further development of SENTI-202 for acute myeloid leukemia (AML) towards clinical development. The Direct to Phase II SBIR contract will provide funding over two years from the NCI of the National Institutes of Health (NIH) and is titled: “Logic-Gated Chimeric Antigen Receptor-Natural Killer Cell Therapy for Acute Myeloid Leukemia.” With the award of this contract, the

288

SENTI-202 program will be funded in part with Federal funds from the National Cancer Institute, National Institutes of Health, Department of Health and Human Services, under Contract No. 75N91021C00026.

Potential Collaboration Around Gene Circuits and GMP Manufacturing

We may seek to leverage our manufacturing capabilities and proposed cGMP facility to enable us to expand the application of our gene circuit technology through a partnership in the biomanufacturing space. While we intend to use our proprietary gene circuit technology and manufacturing facility primarily for therapeutic product development and commercialization, our technology and facility can also be applied to noncompetitive biomanufacturing applications, which we believe is an approach well-suited for partnering. A potential biomanufacturing partnership could involve retaining operational control and manufacturing supply of our therapeutic candidates, while our partner could control part of the facility for its own use. The following is an illustrative depiction of the framework for a potential biomanufacturing partnership:

LOGO

We currently have no agreements or commitments for a manufacturing partnership, and we could determine to advance our manufacturing plans without a partner.

Competition

We are aware of other companies that are developing technologies that may compete with elements of our gene circuit platform technologies, including A2 Biotherapeutics, Inc., Arsenal Biosciences, Inc., Beam Therapeutics Inc., CRISPR Therapeutics AG, Encoded Therapeutics, Inc., ImmPACT Bio USA, Inc., Intellia Therapeutics, Inc., MeiraGTx Holdings plc, Obsidian Therapeutics, Inc. and Strand Therapeutics Inc. We are also aware of other companies that are focused on the application of engineered CAR-based immune cell therapies, including NK cells, to oncology, and such competitors include Allogene Therapeutics, Inc., Artiva Biotherapeutics, Inc., Atara Biotherapeutics, Inc., Bristol-Myers Squibb Company, Century Therapeutics, Inc., Caribou Biosciences, Inc., Catamaran Bio, Inc., Cytovia Therapeutics, Inc., Editas Medicine, Inc., Fate Therapeutics, Inc., Gilead Sciences, Inc., Lyell Immunopharma, Inc., Nkarta, Inc., Sana Biotechnology, Inc., Shoreline Biosciences, Inc., Takeda Pharmaceutical Company and Vor Biopharma Inc. Some of these companies may have substantially greater financial and other resources than we have, such as larger research and development staff and well-established marketing and salesforces. Mergers and acquisitions in the biotechnology industry may result in even greater resource concentration among a smaller number of competitors. Smaller or early-stage companies may also prove to be significant competitors, either alone or through collaborative arrangements with large and established companies.

These companies compete with us in recruiting scientific and managerial talent. Our success will partially depend on our ability to obtain, maintain, enforce and defend patents and other intellectual property rights with

289

respect to our product candidates. Our competitors may obtain FDA or other regulatory approval for their product candidates more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop.

Intellectual Property

Intellectual property is the foundation of our company and not only defines who we are, but is the lens through which we implement our business strategy and research and development. Our overall strategy is to own and control all intellectual property related to our gene circuits. We protect our proprietary technology and intellectual property rights through a combination of wholly-owned patent rights, licensed patent rights in particular fields of use, trademark rights, trade secrets and know-how, contractual provisions and confidentiality procedures. Our general strategy includes protecting our proprietary technology and intellectual property rights domestically and in certain key foreign markets. We continually grow and supplement our intellectual property portfolio with new filings and applications not only to strengthen the protection of proprietary technology and intellectual property rights, but also to protect and support the development and commercialization of current and future product candidates. In addition, we always seek to protect our technological innovations and branding efforts by filing new patent and trademark applications at the appropriate time and strategically relevant jurisdictions.

Our patent portfolio relates to our ongoing research and development activities and includes a combination of patents and pending patent applications licensed from third parties, pending patent applications jointly owned with third parties, and patent applications solely owned by us. The patents and pending patent applications in our portfolio can be categorized as relating to our gene circuit platform technologies, including Logic Gating gene circuits, Multi-Arming gene circuits, Regulator Dial gene circuits and Smart Sensor gene circuits; our product candidates, including SENTI-202, SENTI-301 and SENTI-401, as well as other pipeline product candidates; and alternative technologies. Certain of our issued patents and pending patent applications are exclusively or co-exclusively licensed to us in certain therapeutic fields of use from third-party licensors. As of January 31, 2022, our patent portfolio includes three issued U.S. patents, four issued foreign patents, 27 pending U.S. provisional and utility patent applications, 76 pending foreign utility patent applications, and11 Patent Cooperation Treaty, or PCT, applications, that have not entered national stage.

With respect to our issued patents, we own one issued U.S. patent and we license from the NCI one issued U.S. patent and four issued foreign patents. Further, we license from a third-party licensor one additional issued U.S. patent. With respect to our pending provisional and utility patent applications, we own or co-own 24 pending U.S. provisional and utility patent applications, 54 pending foreign utility patent applications and 11 PCT applications, that have not entered national stage, and we license from third parties (including the NCI) three pending U.S. utility patent applications and 22 pending foreign utility patent applications. The estimated expiration dates of the issued patents are between 2030 and 2033, and the estimated expiration dates of the pending provisional and utility patent applications, to the extent they issue, will be between 2036 and 2043, without accounting for any patent term adjustments or extensions.

We have five pending U.S. provisional and utility patent applications, 33 pending foreign utility applications, and six PCT applications that have not entered national stage related to our SENTI-202 product candidate, of which 24 are solely owned or co-owned by us, with the remaining licensed from the NCI. These patent applications relate to composition of matter, method of preparing and method of treatment. The estimated expiration dates of the pending provisional and utility patent applications, to the extent they issue, will be between 2037 and 2042, without accounting for any patent term adjustments or extensions.

290

We have one issued U.S. patent and four issued foreign patents licensed from the NCI, 11 solely owned pending U.S. provisional and utility patent applications, 17 solely owned pending foreign utility applications, and three PCT applications that have not entered national stage related to our SENTI-301 product candidate. These patent applications relate to composition of matter, method of preparing and method of treatment. The issued patents are expected to expire in 2033, without accounting for any patent term adjustments or extensions. The estimated expiration dates of the pending provisional and utility patent applications, to the extent they issue, will be between 2039 and 2042, without accounting for any patent term adjustments or extensions.

We solely own or co-own six pending U.S. provisional and utility patent applications, 16 pending foreign utility applications and six PCT applications that have not entered national stage related to our SENTI-401 product candidate. These patent applications relate to composition of matter, method of preparing and method of treatment. The estimated expiration dates of the pending provisional and utility patent applications, to the extent they issue, will be between 2039 and 2042, without accounting for any patent term adjustments or extensions.

We also utilize trademark rights to protect our brand. As of January 31, 2022, we are listed as owners of one registered United States trademark, five United States pending and allowed trademarks, four foreign registered trademarks, 12 foreign granted trademarks, and one foreign pending trademark. We own the filed trademarks “SENTI,” “SENTI BIOSCIENCES,” “SENTI BIO,” Senti’s “S” logo, and “PRO-DIAL” in the United States and in certain foreign countries. We have also registered multiple internet domain names to further supplement the protection of our brand.

Government Regulation

The U.S. Food and Drug Administration, or FDA, and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensively regulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, record keeping, approval, advertising, promotion, marketing, sampling post-approval monitoring and post-approval reporting of biologics such as those we are developing. Any product candidates that we develop must be approved by the FDA before they may be legally marketed in the United States and by the appropriate foreign regulatory agency before they may be legally marketed in those foreign countries. Generally, our activities in other countries will be subject to regulation that is similar in nature and scope as that imposed in the United States, although there can be important differences.

U.S. Biologics Regulation

In the United States, biological products are subject to regulation under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and other federal, state, local and foreign statutes and their implementing regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. The process required by the FDA before biologics may be marketed in the United States generally involves the following:

•

completion of preclinical laboratory tests and animal studies performed in accordance with the FDA’s Good Laboratory Practice requirements, or GLP;

•

submission to the FDA of an investigational new drug application, or IND, which must become effective before clinical trials may begin;

•

approval by an institutional review board, or IRB, or ethics committee at each clinical site before the trial is commenced;

•

performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred to as good clinical practice, or GCP, regulations and any additional requirements for the protection of human research subjects and their health information to establish the safety, purity and potency of the proposed biologic product candidate for its intended purpose;

291

•

preparation of and submission to the FDA of a Biologics License Application, or BLA, after completion of all pivotal clinical trials;

•

satisfactory completion of an FDA Advisory Committee review, if applicable;

•

a determination by the FDA within 60 days of its receipt of a BLA to file the application for review;

•

satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the proposed product is produced to assess compliance with cGMP, and to assure that the facilities, methods and controls are adequate to preserve the biological product’s continued safety, purity and potency and, if applicable, to assess compliance with the FDA’s current Good Tissue Practice, or cGTP, requirements for the use of human cellular and tissue products, and of selected clinical investigation sites to assess compliance with GCPs;

•

potential FDA audit of the nonclinical and clinical study sites that generated the data in support of the BLA; and

•

FDA review and approval of the BLA to permit commercial marketing of the product for particular indications for use in the United States.

Before testing any biological product candidate in humans, the product candidate enters the preclinical testing stage. Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs.

Prior to beginning the first clinical trial with a product candidate in the United States, we must submit an IND to the FDA. An IND is a request for authorization from the FDA to administer an investigational new drug to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for clinical studies. Some preclinical testing may continue even after the IND is submitted. The IND also includes results of animal and in vitro studies assessing the toxicology, pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product; chemistry, manufacturing and controls information; and any available human data or literature to support the use of the investigational product. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

Clinical trials involve the administration of the investigational product to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. Clinical trials are conducted

292

under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A separate submission to the existing IND must be made for each successive clinical trial conducted during product development and for any subsequent protocol amendments. Furthermore, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at that site, and must monitor the study until completed. An IRB is charged with protecting the welfare and rights of trial participants and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. Regulatory authorities, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some studies also include oversight by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to certain data from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries.

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap or be combined:

•

Phase 1—The investigational product is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness. In the case of some products for severe or life-threatening diseases, such as cancer, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

•

Phase 2—The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages, dose tolerance and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

•

Phase 3—The investigational product is administered to an expanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for product approval. Generally, two adequate and well-controlled Phase 3 clinical trials are required by the FDA for approval of a BLA.

In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to gain more information about the product in the intended therapeutic indication, particularly for long-term safety follow-up. Completion of these so-called Phase 4 studies may also be made a condition to approval of the BLA.

Concurrent with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics of the product candidate, and must finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, must develop methods for testing the safety, purity and potency of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

293

BLA Submission and Review by the FDA

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include all relevant data available from preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of the product, or from a number of alternative sources, including studies initiated by independent investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and effectiveness of the investigational drug product to the satisfaction of the FDA. The submission of a BLA requires payment of a substantial application user fee to the FDA, unless a waiver or exemption applies.

Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the FDA accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing.

Once a BLA has been accepted for filing, the FDA’s goal is to review standard applications within ten months after the filing date, or, if the application qualifies for priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process may also be extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things, whether a product is safe, pure and potent and the facility in which it is manufactured, processed, packed or held meets standards designed to assure the product’s continued safety, purity and potency. The FDA may also convene an advisory committee to provide clinical insight on application review questions. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

Before approving a BLA, the FDA will typically inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP and adequate to assure consistent production of the product within required specifications. For a product candidate that is also a human cellular or tissue product, the FDA also will not approve the application if the manufacturer is not in compliance with cGTPs. These are FDA regulations that govern the methods used in, and the facilities and controls used for, the manufacture of human cells, tissues, and cellular and tissue based products, or HCT/Ps, which are human cells or tissue intended for implantation, transplant, infusion, or transfer into a human recipient. The primary intent of the GTP requirements is to ensure that cell and tissue based products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations also require tissue establishments to register and list their HCT/Ps with the FDA and, when applicable, to evaluate donors through screening and testing. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. If the FDA determines that the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. Notwithstanding the submission of any requested additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval.

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response Letter, or CRL. An approval letter authorizes commercial marketing of the product with

294

specific prescribing information for specific indications. A CRL indicates that the review cycle of the application is complete, and the application will not be approved in its present form. A CRL will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the CRL without first conducting required inspections, testing submitted product lots, and/or reviewing proposed labeling. In issuing the CRL, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product. If a CRL is issued, the sponsor must resubmit the BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and information are submitted, the FDA may decide that the BLA does not satisfy the criteria for approval.

If regulatory approval of a product is granted, such approval will be granted for particular indications and may entail limitations on the indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation Strategy, or REMS, to ensure the benefits of the product outweigh its risks, or otherwise limit the scope of any approval. A REMS is a safety strategy implemented to manage a known or potential serious risk associated with a product and to enable patients to have continued access to such medicines by managing their safe use, and could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more Phase 4 post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies.

Expedited Development and Review Programs

The FDA offers a number of expedited development and review programs for qualifying product candidates. For example, new biological products are eligible for fast track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to address unmet medical needs for the disease or condition. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a new biologic may request that the FDA designate the biologic as a fast track product at any time during the clinical development of the product. The sponsor of a fast track product has opportunities for more frequent interactions with the applicable FDA review team during product development and, once a BLA is submitted, the product candidate may be eligible for priority review. A fast track product may also be eligible for rolling review, where the FDA may consider for review sections of the BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept sections of the BLA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the BLA.

A product candidate intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation to expedite its development and review. A product candidate can receive breakthrough therapy designation if preliminary clinical evidence indicates that the product candidate, alone or in combination with one or more other drugs or biologics, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. The designation includes all of the fast track program features, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product candidate, including involvement of senior managers.

295

Any marketing application for a biologic submitted to the FDA for approval, including a product candidate with a fast track designation and/or breakthrough therapy designation, may be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. A product candidate is eligible for priority review if it has the potential to provide safe and effective therapy where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis or prevention of a disease compared to marketed products. The FDA will attempt to direct additional resources to the evaluation of an application for a new biological product designated for priority review in an effort to facilitate the review. For original BLAs, priority review designation means the FDA’s goal is to take action on the marketing application within six months of the 60-day filing date (as compared to ten months under standard review).

Additionally, product candidates studied for their safety and effectiveness in treating serious or life-threatening diseases or conditions may receive accelerated approval upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of accelerated approval, the FDA will generally require the sponsor to perform adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit. Products receiving accelerated approval may be subject to expedited withdrawal procedures if the sponsor fails to conduct the required post-marketing studies or if such studies fail to verify the predicted clinical benefit. In addition, for products being considered for accelerated approval, the FDA generally requires, unless otherwise informed by FDA, that all advertising and promotional materials intended for dissemination or publication within 120 days of marketing approval be submitted to FDA for review during the pre-approval period.

In 2017, the FDA established a new regenerative medicine advanced therapy, or RMAT, designation, which is intended to facilitate an efficient development program for, and expedite review of, any biologic that meets the following criteria: (i) the biologic qualifies as a RMAT, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any combination product using such therapies or products, with limited exceptions; (ii) the biologic is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and (iii) preliminary clinical evidence indicates that the biologic has the potential to address unmet medical needs for such a disease or condition. RMAT designation provides all the benefits of breakthrough therapy designation, including more frequent meetings with the FDA to discuss the development plan for the product candidate and eligibility for rolling review and priority review. Product candidates granted RMAT designation may also be eligible for accelerated approval on the basis of a surrogate or intermediate endpoint reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from a meaningful number of clinical trial sites, including through expansion of trials to additional sites. RMAT-designated products that receive accelerated approval may, as appropriate, fulfill their post-approval requirements through submission of clinical evidence, clinical studies, patient registries, or other sources of real-world evidence (such as electronic health records); through the collection of larger confirmatory data sets; or via post-approval monitoring of all patients treated with such therapy prior to approval of such therapy.

Fast track designation, breakthrough therapy designation, priority review, accelerated approval, and RMAT designation do not change the standards for approval but may expedite the development or approval process. Even if a product candidate qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan designation to a biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 individuals in the United States and when there

296

is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that biologic. Orphan drug designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.

In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. In addition, if a product that has orphan drug designation subsequently receives the first FDA approval for a particular drug or biologic for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Competitors may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval of the same biological product as defined by the FDA or if our product candidate is determined to be contained within the competitor’s product for the same indication or disease.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or, as noted above, if a second applicant demonstrates that its product is clinically superior to the approved product with orphan exclusivity or the manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

Post-Approval Requirements

Biologics are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual program fees for any marketed products. Biologic manufacturers and other entities involved in the manufacture and distribution of approved biological products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and other laws, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Manufacturers and other parties involved in the drug supply chain for prescription drug products must also comply with product tracking and tracing requirements and for notifying the FDA of counterfeit, diverted, stolen and intentionally adulterated products or products that are otherwise unfit for distribution in the United States. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain GMP compliance. Changes to the manufacturing process or facility are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown

297

problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

•

fines, warning letters, or untitled letters;

•

clinical holds on clinical studies;

•

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of product license approvals;

•

product seizure or detention, or refusal to permit the import or export of products;

•

consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs;

•

mandated modification of promotional materials and labeling and the issuance of corrective information;

•

the issuance of safety alerts, Dear Healthcare Provider letters, press releases and other communications containing warnings or other safety information about the product; or

•

injunctions or the imposition of civil or criminal penalties.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures.

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined companies from engaging in off-label promotion. The FDA and other regulatory agencies have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, clinical hold, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. Physicians may prescribe, in their independent professional and medical judgment, legally available products for uses that are not described in the product’s labeling and that differ from those tested and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of off-label use of their products.

Biosimilars and Reference Product Exclusivity

298

The Affordable Care Act, signed into law in 2010, includes a subtitle called the Biologics Price Competition and Innovation Act, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars.

Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, animal studies, and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. However, complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy law.

A biological product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study. The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation, and impact of the BPCIA is subject to significant uncertainty.

Government Regulation Outside of the United States

In addition to regulations in the United States, we will be subject to a variety of regulations in other jurisdictions governing, among other things, clinical studies and any commercial sales and distribution of our products. Because biologically sourced raw materials are subject to unique contamination risks, their use may be restricted in some countries.

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in foreign countries prior to the commencement of clinical studies or marketing of the product in those countries. Certain countries outside of the United States have a similar process that requires the submission of a clinical study application much like the IND prior to the commencement of human clinical studies. In the European Union, for example, a CTA must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and the IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical study development may proceed.

The requirements and process governing the conduct of clinical studies, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical studies are conducted in accordance with

299

GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

To obtain regulatory approval of an investigational biological product under European Union regulatory systems, we must submit a marketing authorization application. The application used to file the BLA in the United States is similar to that required in the European Union, with the exception of, among other things, country-specific document requirements. The European Union also provides opportunities for market exclusivity. For example, in the European Union, upon receiving marketing authorization, new chemical entities generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in the European Union from referencing the innovator’s data to assess a generic application. During the additional two-year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic product can be marketed until the expiration of the market exclusivity. However, there is no guarantee that a product will be considered by the European Union’s regulatory authorities to be a new chemical entity, and products may not qualify for data exclusivity. Products receiving orphan designation in the European Union can receive ten years of market exclusivity, during which time no similar medicinal product for the same indication may be placed on the market. An orphan product can also obtain an additional two years of market exclusivity in the European Union for pediatric studies. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications.

The criteria for designating an “orphan medicinal product” in the European Union are similar in principle to those in the United States. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as orphan if (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in 10,000 persons in the European Union when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the European Union to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the European Union, or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC) 847/2000. Orphan medicinal products are eligible for financial incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization, entitled to ten years of market exclusivity for the approved therapeutic indication. The application for orphan drug designation must be submitted before the application for marketing authorization. The applicant will receive a fee reduction for the marketing authorization application if the orphan drug designation has been granted, but not if the designation is still pending at the time the marketing authorization is submitted. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity. Additionally, marketing authorization may be granted to a similar product for the same indication at any time if:

•

The second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior;

•

The applicant consents to a second orphan medicinal product application; or

•

The applicant cannot supply enough orphan medicinal product.

For other countries outside of the European Union, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical studies, product licensing, pricing and reimbursement vary from country to country. In all cases, again, the clinical studies are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

300

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Other Healthcare Laws

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their business and may constrain the financial arrangements and relationships through which we research, as well as, sell, market and distribute any products for which we obtain marketing approval. Such laws include, without limitation, federal and state anti-kickback, fraud and abuse, false claims, data privacy and security and physician and other health care provider transparency laws and regulations.

In order to distribute products commercially, we must also comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, track and report gifts, compensation and other remuneration made to physicians and other healthcare providers, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including without limitation, civil, criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to allow us to enter into government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. For information regarding risks related to these compliance requirements, see the section titled “Risk Factors—Risks Related to Government Regulations.”

Coverage and Reimbursement

Sales of any product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state, and foreign government healthcare programs, commercial insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. These third-party payors are increasingly reducing coverage and reimbursement for medical products, drugs and services. Obtaining coverage and adequate reimbursement for our product candidates may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. Similarly, because our product candidates are physician-administered, separate reimbursement for the product itself may or may not be available. Instead, the administering physician may or may not be reimbursed for providing the treatment or procedure in which our product is used.

In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and

301

requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product and also have a material adverse effect on sales.

Healthcare Reform

Payors, whether domestic or foreign, or governmental or private, are developing increasingly sophisticated methods of controlling healthcare costs and those methods are not always specifically adapted for new technologies such as gene therapy and therapies addressing rare diseases such as those we are developing. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could impact our ability to sell our products profitably.

In the United States, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, each as amended, collectively known as the ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and private insurers, and significantly affected the pharmaceutical industry. The ACA contained a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement adjustments and changes to fraud and abuse laws. For example, the ACA:

•

increased the minimum level of Medicaid rebates payable by manufacturers of brand name drugs from 15.1% to 23.1% of the average manufacturer price;

•

required collection of rebates for drugs paid by Medicaid managed care organizations;

•

required manufacturers to participate in a coverage gap discount program, under which they must now agree to offer 70 percent point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; and

•

imposed a non-deductible annual fee on pharmaceutical manufacturers or importers who sell “branded prescription drugs” to specified federal government programs.

On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an Executive Order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The Executive Order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reform measures of the Biden administrations or other efforts, if any, to challenge repeal or replace the ACA, will impact our business.

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. For example, on March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. Further, in August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs, including aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect in April 2013 and, due to

302

subsequent legislative amendments to the statute, will remain in effect through 2030 unless additional action is taken by Congress. Pursuant to the Coronavirus Aid, Relief, and Economic Security Act, also known as the CARES Act, as well as subsequent legislation, these reductions have been suspended from May 1, 2020 through December 31, 2021 due to the COVID-19 pandemic.

Further, on May 30, 2018, the Right to Try Act was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries, proposed and enacted legislation and executive orders issued by the previous administration designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. The likelihood of success of these and other measures initiated by the previous administration is uncertain, particularly in light of the new Biden administration. It is also possible that additional governmental action is taken in response to the COVID-19 pandemic. Individual states in the United States have also become increasingly active in implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

Data Privacy and Security Laws

We also are or will become subject to privacy laws in the jurisdictions in which we are established or in which we sell or market our products or run clinical trials. For example, in Europe we are subject to the GDPR in relation to our collection, control, processing and other use of personal data (i.e., data relating to an identifiable living individual). We process personal data in relation to participants in our clinical trials in the EEA, including health and medical information of these participants. The GDPR also provides that individual EEA countries may introduce further conditions of their own, including limitations which could limit our ability to collect, use and share personal data.

The GDPR imposes onerous accountability obligations requiring data controllers and processors to maintain a record of their data processing and implement policies as part of its mandated privacy governance framework. It also requires data controllers to be transparent and disclose to data subjects (in a concise, intelligible and easily accessible form) how their personal information is to be used; imposes limitations on retention of personal data; defines pseudonymized (i.e., key-coded) data; introduces mandatory data breach notification requirements; and sets higher standards for data controllers to demonstrate that they have obtained valid consent for certain data processing activities. Fines for certain breaches of the GDPR are significant: up to the greater of €20 million or 4% of total global annual turnover. A breach of the GDPR or other applicable privacy and data protection laws and regulations could also result in regulatory investigations, reputational damage, orders to cease/change our use of data, enforcement notices, or potential civil claims including class action type litigation. Further, from January 1, 2021, we have to comply with the GDPR and separately the UK GDPR, which, together with the amended UK Data Protection Act 2018, retains the GDPR in UK national law. The GDPR and the UK GDPR each have the ability to fine up to the greater of €20 million/ £17 million or 4% of global turnover. Further, the relationship between the United Kingdom and the European Union in relation to certain aspects of data protection law remains unclear, including how data transfers between European Union member states and the United Kingdom will be treated and how United Kingdom data protection laws and regulations will develop in the medium to longer term. Currently there is a four to six-month grace period agreed in the European Union and

303

United Kingdom Trade and Cooperation Agreement, ending June 30, 2021 at the latest, whilst the parties discuss an adequacy decision. The European Commission published a draft adequacy decision on February 19, 2021. If adopted, the decision will enable data transfers from European Union member states to the United Kingdom for a four-year period, subject to subsequent extensions. These changes may lead to additional compliance costs and could increase our overall risk.

In addition, the GDPR places restrictions on cross-border data transfers. Certain aspects of cross-border data transfers under the GDPR are uncertain as the result of legal proceedings in the European Union, including a recent decision by the Court of Justice for the European Union that invalidated the EU-U.S. Privacy Shield and, to some extent, called into question the efficacy and legality of using standard contractual clauses. This may increase the complexity of transferring personal data across borders. The GDPR will increase our responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, including as implemented by individual countries. We are also subject to European Union rules with respect to cross-border transfers of personal data out of the EEA. Recent legal developments in the European Union have created complexity and uncertainty regarding transfers of personal data from the EEA to other countries whose data protection standards have not been deemed “adequate” by the European Commission (including the United States). On July 16, 2020, the Court of Justice of the European Union, or CJEU, invalidated the EU-US Privacy Shield Framework, or Privacy Shield, under which personal data could be transferred from the EEA to US entities who had self-certified under the Privacy Shield scheme. While the CJEU upheld the adequacy, subject to certain conditions, of the standard contractual clauses (a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism), future regulatory guidance could result in changes to the use of standard contractual clauses. As supervisory authorities issue further guidance on personal data export mechanisms, including circumstances where the standard contractual clauses cannot be used, and/or start taking enforcement action, we could suffer additional costs, complaints and/or regulatory investigations or fines, and/or if we are otherwise unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner in which we provide our services, the geographical location or segregation of our relevant systems and operations, and could adversely affect our financial results.

Further, the exit of the United Kingdom, or UK, from the European Union, often referred to as Brexit, has created uncertainty with regard to data protection regulation in the UK. Specifically, the UK exited the European Union on January 1, 2020, subject to a transition period that ended December 31, 2020. Under the post-Brexit Trade and Cooperation Agreement between the European Union and the UK, the UK and European Union have agreed that transfers of personal data to the UK from EEA member states will not be treated as ‘restricted transfers’ to a non-EEA country for a period of up to four months from January 1, 2021, plus a potential further two months extension, or the Extended Adequacy Assessment Period. Although the current maximum duration of the Extended Adequacy Assessment Period is six months, it may end sooner, for example, in the event that the European Commission adopts an adequacy decision in respect of the UK, or the UK amends the UK GDPR and/or makes certain changes regarding data transfers under the UK GDPR/Data Protection Act 2018 without the consent of the European Union (unless those amendments or decisions are made simply to keep relevant UK laws aligned with the European Union’s data protection regime). If the European Commission does not adopt an ‘adequacy decision’ in respect of the UK prior to the expiry of the Extended Adequacy Assessment Period, from that point onwards the UK will be an ‘inadequate third country’ under the GDPR and transfers of personal data from the EEA to the UK will require a ‘transfer mechanism’ such as the Standard Contractual Clauses.

In the United States, numerous federal and state laws and regulations, including data breach notification laws, health information privacy and security laws, including HIPAA, and federal and state consumer protection laws and regulations (e.g., Section 5 of the Federal Trade Commission Act) that govern the collection, use, disclosure, and protection of health-related and other personal information could apply to our operations or the operations of our partners. In addition, certain state laws govern the privacy and security of personal information, including health-related information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating

304

compliance efforts. For example, California enacted the CCPA, which creates individual privacy rights for California consumers (as defined in the law) and places increased privacy and security obligations on entities handling certain personal data of consumers or households. The CCPA requires covered companies to provide new disclosure to consumers about such companies’ data collection, use and sharing practices, provide such consumers new ways to opt-out of certain sales or transfers of personal information, and provide consumers with additional causes of action. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information. This private right of action may increase the likelihood of, and risks associated with, data breach litigation. The CCPA became effective on January 1, 2020, and (a) allows the California Attorney General to impose civil penalties for violations and (b) authorizes private lawsuits to recover statutory damages for certain data breaches. In addition, laws in all 50 U.S. states require businesses to provide notice to consumers whose personal information has been disclosed as a result of a data breach. State laws are changing rapidly and there is discussion in the U.S. Congress of a new comprehensive federal data privacy law to which we would become subject if it is enacted. The CCPA may impact our business activities and exemplifies the vulnerability of our business to the evolving regulatory environment related to personal data and protected health information. Additionally, a new privacy law, the California Privacy Rights Act, or CPRA, recently passed in California. The CPRA significantly modifies the CCPA and imposes additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also expand the types of data breaches subject to the CCPA’s private right of action, provide for increased penalties for CPRA violations concerning California residents under the age of 16 and create a new California data protection agency authorized to issue substantive regulations, and could result in increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance investment and potential business process changes may be required. Ensuring compliance with the CPRA could require us to incur additional costs and expenses.

In order to distribute products commercially, we must comply with state laws that require the registration of manufacturers and wholesale distributors of pharmaceutical products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, track and report gifts, compensation and other remuneration made to physicians and other healthcare providers, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare and privacy laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including without limitation, civil, criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to allow us to enter into government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. For information regarding risks related to these compliance requirements, see the section titled “Risk Factors—Risks Related to Government Regulation.”

Facilities

Our corporate headquarters are located in South San Francisco, California, where we lease approximately 40,000 square feet of office and research and development space pursuant to a lease agreement which

305

commenced on April 25, 2019 and expires on April 30, 2027, with an option to extend for eight years. In Alameda, California, we lease approximately 92,000 square feet of space pursuant to a lease agreement which initiated on June 3, 2021 and expires on September 30, 2032, with two options to extend for five years each. Within this space, we have begun the build-out of a cell therapy manufacturing facility designed to meet Current Good Manufacturing Practices (cGMP) with the goal of providing clinical and commercial-scale manufacturing for multiple allogeneic, or “off-the-shelf”, chimeric antigen receptor (CAR) natural killer (NK) cell product candidates. We believe that our existing facilities are suitable and adequate for our needs.

Employees and Human Capital Resources

As of March 25, 2022, we had 89 employees, all of whom were full-time, consisting of clinical, research, operations, regulatory, finance and business development personnel. 28 of our employees hold Ph.D. or M.D. degrees. None of our employees are subject to a collective bargaining agreement. We consider our relationship with our employees to be good.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. The principal purposes of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of stock-based compensation awards, in order to increase stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities and achieve our objectives.

Periodic Reporting and Financial Information

Upon consummation of the Business Combination, we expect to be a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company if (1) the market value of our common stock held by non-affiliates is less than $250 million as of the last business day of the second fiscal quarter, or (2) our annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter are less than $100 million and the market value of our common stock held by non-affiliates is less than $700 million as of the last business day of the second fiscal quarter.

Legal Proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not currently a party to any material legal proceedings. Regardless of outcome, such proceedings or claims can have an adverse impact on us because of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

Cautionary Statement Regarding Forward-Looking Statements

In addition to historical information, some of the information contained in this discussion and analysis or set forth elsewhere in this proxy statement/prospectus, including information with respect to our plans and strategy for our business, future financial performance, expense levels and liquidity sources, includes forward-looking statements that involve risks and uncertainties. You should read the sections of this proxy statement/prospectus titled “Forward-Looking Statements” and “Risk Factors” for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

Senti is a preclinical biotechnology company developing next-generation cell and gene therapies engineered with its gene circuit platform technologies to fight challenging diseases. Senti’s mission is to create a new generation of smarter therapies that can outmaneuver complex diseases in ways previously not implemented by conventional medicines. To accomplish this mission, Senti has built a synthetic biology platform that it believes may enable it to program next-generation cell and gene therapies with what it refers to as “gene circuits.” These gene circuits, which Senti created from novel and proprietary combinations of genetic parts, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Senti aims to design and optimize gene circuits through its Design-Build-Test-Learn Engine or DBTL Engine, to improve the “intelligence” of cell and gene therapies in order to enhance their therapeutic effectiveness against a broad range of diseases that conventional medicines are unable to address. Senti is designing its gene circuit platform technologies to be applied in a modality-agnostic manner, with applicability to natural killer (NK) cells, T cells, tumor infiltrating lymphocytes (“TILs”), stem cells including Hematopoietic Stem Cells (“HSCs”), in vivo gene therapy and messenger ribonucleic acid (mRNA). All of Senti’s current product candidates are in preclinical development. Senti’s lead product candidates currently utilize allogeneic chimeric antigen receptor (“CAR”) NK cells outfitted with its gene circuit technologies in several oncology indications with currently high unmet need. Senti expects to file investigational new drug applications (“INDs”) for multiple product candidates starting in 2023.

Since our inception, we have funded our operations almost exclusively with proceeds from the sale and issuance of shares of our redeemable convertible preferred stock and debt financings, and we have devoted substantially all of our resources to organizing and staffing our company, business planning, raising capital, developing and optimizing our platform technologies, identifying potential product candidates, undertaking research and preclinical studies and clinical trial planning activities, engaging in manufacturing for our development programs, establishing and enhancing our intellectual property portfolio, and providing general and administrative support for these operations. Through December 31, 2021, we have received gross proceeds of $158.1 million from sales of our redeemable convertible preferred stock including borrowings under convertible notes, which converted into redeemable convertible preferred stock in 2018 and 2020.

307

We have incurred net losses of $55.3 million and $19.9 million for the years ended December 31, 2021 and 2020, respectively. We expect to continue to incur significant losses for the foreseeable future. As of December 31, 2021, we had cash and cash equivalents of $56.0 million, and an accumulated deficit of $115.1 million.

We anticipate that our expenses and operating losses will increase substantially over the foreseeable future. The expected increase in expenses will be driven in large part by our ongoing activities, if and as we:

•

continue to advance our gene circuit platform technologies;

•

continue preclinical development of our current and future product candidates and initiate additional preclinical studies;

•

commence clinical studies of our current and future product candidates;

•

establish our manufacturing capability, including developing our contract development and manufacturing relationships, and building our internal manufacturing facilities;

•

acquire and license technologies aligned with our gene circuit platform technologies;

•

seek regulatory approval of our current and future product candidates;

•

expand our operational, financial, and management systems and increase personnel, including personnel to support our preclinical and clinical development, manufacturing and commercialization efforts;

•

continue to develop, grow, perfect, and defend our intellectual property portfolio; and

•

incur additional legal, accounting, or other expenses in operating our business, including the additional costs associated with operating as a public company.

In addition, in 2021, we began construction on a dedicated in-house, state-of-the-art current good manufacturing practices “cGMP” facility to support clinical and commercial-scale production of multiple allogeneic NK cell product candidates. We anticipate that this facility will become operational in time to support initial clinical trials for our lead product candidates. Our manufacturing facility is designed to leverage the latest cell therapy process technologies as we strive to maximize scalability and minimize cost of goods.

As of April 1, 2022, the issuance date of the consolidated financial statements for the year ended December 31, 2021, the Company concluded that substantial doubt existed about the Company’s ability to continue as a going concern for one year from the issuance date of the annual consolidated financial statements. In light of these concerns, our independent registered public accounting firm included in its opinion for the year ended December 31, 2021 an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern within one year from April 1, 2022.

We believe that our cash and cash equivalents on hand as of December 31, 2021 are not sufficient to fund our operations for the next twelve months from the date of this proxy statement/prospectus.

During 2021, widespread availability of COVID-19 vaccines in the United States and elsewhere in the world, combined with government assistance programs, fiscal policies and other factors, led to a rebound in the global economy as several states and countries began to re-open and loosen many COVID-19 related restrictions. Nonetheless, the COVID-19 pandemic remains a global health crisis and continues to evolve. Despite the emergence of new variants, increased public safety measures and deployment of vaccines, including vaccine boosters, to slow the spread of the virus have resulted in substantial improvements in the global economy throughout 2021 and into early 2022. As of December 31, 2021, we were operating at pre-pandemic levels.

308

Recent Developments

Pending Merger with Dynamics Special Purpose Corp.

On December 19, 2021, we entered into a definitive Business Combination Agreement with Dynamics Special Purpose Corp. (“DYNS”), a publicly traded special purpose acquisition company (“SPAC”). Under the terms of the proposed transaction, we will merge with DYNS at an estimated combined enterprise value of approximately $276.0 million. The cash components of the transaction will be funded by DYNS’ cash in trust of $230.0 million (assuming no redemptions) as well as a $66.8 million private placement of common stock at $10.00 per share from various accredited investors.

On February 12, 2022, we entered into Amendment No. 1 to the Business Combination Agreement to restructure certain option grants made at the time the Business Combination Agreement was signed.

Components of Results of Operations

Total Revenue

We currently have no therapeutic products approved for sale, and we have never generated any revenue from the sale of any therapeutic products. Total revenue consists of contract revenue related to research services provided to customers and grant income which is research funding received from grants.

Our ability to generate product revenues will depend on our partners’ ability to replicate our results and the successful development and eventual commercialization of our product candidates, which we do not expect for the foreseeable future, if ever. We may also look to generate revenue from collaboration and license agreements in the future.

Operating Expenses

Our operating expenses consist of research and development expense and general and administrative expenses.

Research and Development Expenses

Research and development costs consist primarily of costs incurred for the discovery and preclinical development of our product candidates, which include:

•

employee-related expenses, including salaries, related benefits, and stock-based compensation expenses for employees engaged in research and development functions;

•

expenses incurred in connection with research, laboratory consumables and preclinical studies;

•

the cost of consultants engaged in research and development related services and the cost to manufacture drug products for use in our preclinical studies and trials;

•

facilities, depreciation and other expenses, which include allocated expenses for rent and maintenance of facilities, insurance and supplies;

•

costs related to regulatory compliance; and

•

the cost of annual license fees.

We have not historically tracked research and development expenses by program, with the exception of third party research projects. We have various ongoing early stage research and product candidate discovery projects and going forward, we expect to have various products undergoing clinical trials. Our internal resources, employees and infrastructure are not directly tied to any one research or product candidate discovery project and are typically deployed across multiple projects. As such, we do not maintain information regarding these costs incurred for these early stage research and product candidate discovery programs on a project-specific basis.

309

Our direct external development program expenses reflect external costs attributable to our preclinical development candidates selected for further development as well as INDs and clinical development. Such expenses include third-party contract costs relating to manufacturing, clinical trial activities, translational medicine and toxicology activities. We do not allocate internal research and development costs which include personnel, facility costs, laboratory consumables and discovery and research related activities associated with our pipeline because these costs are deployed across multiple programs and our platform, and, as such, are not separately classified.

Research and development expenses consisted of the following (in thousands):


	Year Ended December 31,
	2021		2020
Personnel-related expenses including share-based compensation	$	7,687	$	6,729
External services and supplies		9,041		5,830
Office and facilities		4,680		3,147
Other		549		250

Total	$	21,957	$	15,956

Research and development activities are central to our business model. There are numerous factors associated with the successful commercialization of any of our product candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. In addition, future regulatory factors beyond our control may impact our preclinical development programs. Product candidates in clinical development generally have higher development costs than those in preclinical stages of development, primarily due to the increased size and duration of clinical trials. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical development of any of our product candidates. However, we expect that our research and development expenses and manufacturing costs will increase substantially in connection with our planned preclinical and clinical development activities in the near term and in the future.

The successful development of our current and future product candidates is highly uncertain. This is due to numerous risks and uncertainties, including the following:

•

negative or inconclusive results from our preclinical or clinical trials or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;

•

product-related side effects experienced by participants in our clinical trials or by individuals using therapeutics similar to our product candidates;

•

delays in submitting IND applications or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;

•

conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;

•

delays in enrolling research subjects in clinical trials;

•

high drop-out rates of research subjects;

•

inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

310

•

CMC challenges associated with manufacturing and scaling up biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;

•

greater-than-anticipated clinical trial costs;

•

poor potency or effectiveness of our product candidates during clinical trials;

•

unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;

•

delays as a result of the COVID-19 pandemic or events associated with the pandemic;

•

failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;

•

delays and changes in regulatory requirements, policies and guidelines; and

•

the FDA or other regulatory authorities interpreting our data differently than we do.

A change in the outcome of any of these variables may significantly impact the costs and timing associated with the development of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation, for personnel in executive, finance and other administrative functions. Other significant costs include legal fees relating to corporate matters, professional fees for accounting and consulting services and an allocation of facility-related costs.

We expect our general and administrative expenses will increase for the foreseeable future to support our increased research and development, manufacturing activities, and preclinical and clinical activities and to reflect increased costs associated with operating as a public company. These increased costs will likely include increased expenses for audit, legal, regulatory, tax and related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums and investor relations costs.

Other Income (Expense)

Interest Income, net

Interest income, net consists of interest earned on our cash and cash equivalents, and short-term investments, if any, held during the year, net of interest expense.

Change in Fair Value of Convertible Notes

Our convertible notes have been accounted for at fair value with changes in fair value recorded in earnings at each reporting period through settlement.

Change in Preferred Stock Tranche Liability

Our preferred stock tranche liability has been accounted for at fair value with changes in the fair value recorded in earnings at each reporting period through settlement.

Net loss	$	(55,319	)	$	(19,862	)	$	(35,457	)

Contract revenue. For the years ended December 31, 2021 and 2020, we generated revenue from contracts and license agreements of $2.3 million and $0.4 million, respectively. The increase of $1.9 million was due primarily to a new collaboration agreement entered into in 2021 which led to the recognition of $2.5 million in incremental revenue, partially offset by a $0.6 million decrease in the revenue generated from an existing contract and license agreement, commensurate with decreased research services performed.

Grant income. For the years ended December 31, 2021 and 2020, we generated revenue from grants of $0.5 million and $0.2 million, respectively. The increase of $0.3 million was primarily due to the recognition of revenue related to the Small Business Innovation Research (“SIBR”) SENTI-202 grant funding.

Research and development expenses. Research and development expenses were $22.0 million and $16.0 million for the years ended December 31, 2021 and 2020, respectively. The increase of $6.0 million was primarily due to increase of $3.2 million in lab service costs including costs associated with the new collaborative agreement, $1.5 million in facility costs, $1.0 million in personnel-related expenses, $0.2 million in depreciation expenses and $0.1 million in professional services costs.

General and administrative expenses. General and administrative expenses were $21.3 million and $9.3 million for the years ended December 31, 2021 and 2020, respectively. The increase of $11.9 million was primarily due to increases of $2.9 million in professional services related to legal and accounting services, $2.2 million related to incremental professional, legal and accounting services expenses incurred in connection with the suspended Initial Public Offering (“IPO”), $4.4 million in personnel-related expenses, $1.7 million in stock-based compensation, $0.5 million in facility costs and $0.1 million in costs related to a new directors and officers insurance policy.

312

Interest income, net. Interest income was negligible and $0.1 million for the years ended December 31, 2021 and 2020, respectively, due to greater interest earned in 2020 on higher invested balances.

Change in fair value of convertible note. In August 2020, we recognized an initial loss on the recognition of the convertible note of $0.9 million and thereafter recognized a fair value gain adjustment that reduced the convertible note liability by $0.2 million. There was no equivalent expense during the year ended December 31, 2021.

Change in preferred stock tranche liability. For the year ended December 31, 2021, we recognized a loss of $14.7 million and an increase to the preferred stock tranche liability as a result of an increase in the weighted-average fair value of the tranche feature on a per share basis from $0.012 as of December 31, 2020 to $0.3893 as of May 14, 2021. The increase in the fair value stems primarily from the increase in management’s estimate of the fair value of our Series B redeemable convertible preferred stock resulting from a decrease in time to liquidity as we drew nearer to completing an exit strategy. For the year ended December 31, 2020, we recognized a gain of $5.7 million as a result of a decrease in the weighted-average fair value of the tranche feature on a per share basis from $0.172 as of October 22, 2020 to $0.012 as of December 31, 2020. The decrease in the fair value stems primarily from the increase in management’s estimate of the fair value of our Series B redeemable convertible preferred stock combined with the probabilities of the call option and forward contract.

Liquidity and Capital Resources

Sources of Liquidity

From inception to December 31, 2021, we raised aggregate gross proceeds of $158.1 million from the issuance of shares of our redeemable convertible preferred stock and the issuance of convertible notes.

We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. We have incurred net losses and negative cash flows from operations since our inception and anticipate we will continue to incur net losses for the foreseeable future. As of December 31, 2021, we had $56.0 million in cash and cash equivalents, and an accumulated deficit of $115.1 million, respectively.

We will need substantial additional funding to support our continuing operations and pursue our development strategy. Until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. Adequate funding may not be available to us on acceptable terms, if at all. Should we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back, or discontinue the development and commercialization of our product candidates or delay our efforts to expand our product pipeline. We may also be required to sell or license to other parties’ rights to develop or commercialize our product candidates that we would prefer to retain.

Cash Flows

The following table sets forth a summary of our cash flows for each of the periods indicated (in thousands):


	Year Ended December 31,
	2021			2020
Net cash from operating activities	$	(34,635	)	$	(24,173	)
Net cash from investing activities		(5,543	)		11,358
Net cash from financing activities		68,435			38,051

Net change in cash and cash equivalents	$	28,257		$	25,236

313

Operating Activities

For the year ended December 31, 2021, net cash used in operating activities of $34.6 million was primarily due to our net loss of $55.3 million with non-cash adjustments of $14.7 million for an increase in our estimated preferred stock tranche liability, $3.0 million for depreciation and amortization of operating lease right-of-use assets and $2.3 million for stock-based compensation expense, as well as a $1.8 million increase in deferred revenue, $2.0 million for an increase in accounts payable and accrued and other current liabilities offset by a decrease of $1.1 million in operating lease liabilities, an increase of $1.6 million in prepaid and other assets and an increase of $0.4 in accounts receivable. During the year ended December 31, 2021 the Company expensed $2.2 million of deferred offering costs related to the suspended IPO, all of which was paid and is included in the net cash used in operating activities.

For the year ended December 31, 2020, net cash used in operating activities of $24.2 million was primarily due to our net loss of $19.9 million with non-cash adjustments of $5.7 million for a reduction in the estimated fair value of our preferred stock tranche liability, $2.0 million for depreciation and amortization of operating lease right-of-use assets, and $0.7 million expense for the change in fair value of convertible notes as well as an decrease of $1.3 million in operating lease liabilities.

Investing Activities

For the year ended December 31, 2021, net cash used in investing activities of $5.5 million was due entirely to purchases of property and equipment.

For the year ended December 31, 2020, net cash provided by investing activities of $11.4 million was primarily due to the maturity and purchases of short-term investments of $12.5 million partially offset by purchases of property and equipment of $1.2 million.

Financing Activities

For the year ended December 31, 2021, net cash provided by financing activities of $68.4 million was primarily due to proceeds received of $67.0 million from the issuance of our Series B redeemable convertible preferred stock and $1.5 million from the issuance of common stock upon exercise of stock options.

For the year ended December 31, 2020, net cash provided by financing activities of $38.1 million was primarily due to proceeds received of $30.0 million from the issuance of our Series B redeemable convertible preferred stock and to $8.0 million received from the issuance of notes converted to Series B redeemable convertible preferred stock.

Funding Requirements

Based upon our current operating plans, we believe that our existing cash and cash equivalents will not be sufficient to fund our operations for the next twelve months from the date of this proxy statement/prospectus. However, as noted in the Recent Developments section above, the Company is seeking a potential business combination with Dynamics Special Purpose Corp. which would provide further liquidity to the Company and will be funded by Dynamics’s cash in trust of $230.0 million (assuming no redemptions) as well as a $66.8 million private placement of common stock at $10.00 per share from various accredited investors. In the event the Company does not complete the proposed business combination, we anticipate that we will require additional funding though the precise timing of such needs may prove uncertain as our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. Our assumptions may prove to be inaccurate, and we could deplete our capital resources sooner than we expect. Additionally, the process of testing and manufacturing product candidates in preclinical studies and clinical trials is costly and the timing and expenses in these trials are uncertain.

314

Our future capital requirements will depend on many factors, including:

•

the scope, rate of progress, results and costs of drug discovery, preclinical development, laboratory testing and clinical trials for our product candidates;

•

the number and development requirements of product candidates that we may pursue, and other indications for our current product candidates that we may pursue;

•

the costs, timing and outcome of regulatory review of our product candidates;

•

the scope and costs of constructing and operating our planned cGMP facility and any commercial manufacturing activities;

•

the cost associated with commercializing any approved product candidates;

•

the cost and timing of developing our ability to establish sales and marketing capabilities, if any;

•

the timing and amount of any milestone and royalty payments we are required to make under our present or future license agreements;

•

our ability to establish and maintain collaborations on favorable terms, if at all; and

•

the extent to which we acquire or in-license other product candidates and technologies and associated intellectual property.

In order to improve our liquidity, management is actively pursuing additional financing. We expect our expenses to increase substantially in connection with ongoing activities, particularly as we advance our preclinical activities and clinical trials for our product candidates in development. Accordingly, we will need to obtain substantial additional funding for continuing operations. If we are unable to raise capital when needed, or on attractive terms, we could be forced to delay, reduce or eliminate our research or drug development programs or any future commercialization efforts. Although management continues to pursue these plans, there is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations, if at all.

Accounting standards require that management evaluate whether we have adequate financial resources to continue as a going concern for one year after the date that these consolidated financial statements are available to be issued. Management has determined that additional funds will be needed to continue as a going concern for the period defined in the accounting standards.

Contractual Obligations and Commitments

On June 3, 2021, we entered into a lease agreement for a new cGMP facility in Alameda, California to support planned initial clinical trials for our product candidates. The lease will expire in 2032 with future undiscounted operating lease payments of $46.0 million over an initial lease period of eleven years. See Note 10 - Operating Leases for details into our lease obligations.

In 2021, we began construction of the cGMP facility. As of December 31, 2021 we have paid $2.6 million in construction costs and the purchase commitments amounted to approximately $35.5 million. The agreements with the construction company provide for termination following a certain period after notice. Upon termination we will be responsible for payment for work performed to date.

During the year ended December 31, 2021, we entered into a three-year collaboration and option agreement with BlueRock Therapeutics LP (“BlueRock”) under which the Company granted BlueRock an option to execute

315

an exclusive or non-exclusive license to develop, manufacture and commercialize cell therapy products (See Note 14 to our consolidated financial statements). In consideration for the option, the Company is responsible for up to $10.0 million in research and development costs and expenses associated with the collaboration plan incurred over the three-year term.

We have also entered into license agreements under which we are obligated to make annual maintenance payments of $0.1 million and specified milestone and royalty payments. Milestone and royalty payment obligations under these agreements are contingent upon future events, such as our achievement of specified development, regulatory, and sales milestones, or generating product sales. As of December 31, 2021, we were unable to estimate the timing or likelihood of achieving these milestones or generating future product sales.

We have entered into sponsored research agreements under which we are obligated to pay $1.2 million and $1.0 million in 2022 and 2023, respectively.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements as defined under the rules and regulations of the SEC.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates and assumptions on historical experience, known trends and events, and various other factors that are believed to be reasonable and appropriate under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements included elsewhere in this proxy statement/prospectus, we believe the following accounting policies and estimates to be most critical to the preparation of our consolidated financial statements. We define our critical accounting policies as those under U.S. GAAP that require us to make subjective estimates and judgments about matters that are inherently uncertain and are likely to have a material impact on our financial condition and results of operations, as well as the specific manner in which we apply those principles.

Determination of the Fair Value of Common Stock

We are required to estimate the fair value of our common stock underlying our share-based awards when performing the fair value calculations using the Black-Scholes option pricing model. Because our common stock is not currently publicly traded, the fair value of our common stock underlying our share-based awards has been determined on each grant date by our board of directors, with input from management, considering our most recently available third-party valuation of our common stock.

In the absence of a public trading market for our common stock, on each grant date, our board of directors has made a reasonable determination of the fair value of our common stock based on the information known to us on the date of grant, upon a review of any recent events and their potential impact on the estimated fair value per share of the common stock, and timely valuations from an independent third-party valuation in accordance with guidance provided by the American Institute of Certified Public Accountants, Inc. Practice Aid: Valuation of

316

Privately-Held-Company Equity Securities Issued as Compensation, 2013. In addition, our board of directors considered various objective and subjective factors to determine the fair value of our common stock, including:

•

the estimated value of each security both outstanding and anticipated;

•

the anticipated capital structure that will directly impact the value of the currently outstanding securities;

•

our results of operations and financial position;

•

the status of our research and development efforts;

•

the composition of, and changes to, our management team and board of directors;

•

the lack of liquidity of our common stock as a private company;

•

our stage of development and business strategy and the material risks related to our business and industry;

•

external market conditions affecting the life sciences and biotechnology industry sectors;

•

U.S. and global economic conditions;

•

the results of independent third-party valuations of our common stock;

•

the likelihood of achieving a liquidity event for the holders of our common stock, such as an initial public offering or a sale of our company, given prevailing market conditions; and

•

the market value and volatility of comparable companies.

The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date. In accordance with the Practice Aid, we considered various income, market or asset valuation methods.

Based on our early stage of development and other relevant factors, we appropriately used different valuation methods including a hybrid of the option pricing method, or OPM, and guideline transactions Backsolve method, a hybrid of the OPM and guideline public company methods or a hybrid of OPM, Backsolve method, and Monte Carlo simulation to determine the estimated fair value of our common stock for valuations performed through December 31, 2021. In determining the estimated fair value of our common stock, our Board of Directors also considered the fact that our stockholders could not freely trade our common stock in the public markets. Accordingly, we applied discounts to reflect the lack of marketability of our common stock based on the weighted-average expected time to liquidity.

Our Board of Directors and management develop best estimates based on application of these approaches and the assumptions underlying these valuations, giving careful consideration to the advice from our third-party valuation expert. Such estimates involve inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and we use significantly different assumptions or estimates, our equity-based compensation could be materially different.

Valuation of Preferred Stock Tranche Liability

Our Series B redeemable convertible preferred stock included an obligation whereby the investors agreed to buy, and the Company agreed to sell, additional shares at a fixed price if certain agreed-upon milestones were achieved or at the election of investors. This obligation was determined to be a freestanding financial instrument that should be accounted for as a liability at fair value, and until settlement, the preferred stock tranche liability was revalued at each reporting period with changes in the fair value recorded in earnings. Upon achieving specific milestones, and obtaining Board and stockholder approval, the tranches were called and settled on May 14, 2021. The liability was then extinguished and the fair value was reclassified to redeemable convertible preferred stock.

317

We utilized the Monte Carlo valuation model and/or Black-Scholes option pricing model which incorporated assumptions and estimates, to value the preferred stock tranche feature prior to its settlement. Significant estimates and assumptions impacting the fair value measurement included the estimated fair value per share of the underlying Series B redeemable convertible preferred stock, risk-free rate, expected dividend yield, time to liquidity, expected volatility of the price of the underlying preferred stock and determining the type of option (call option and/or forward contract) and associated probabilities. The most significant assumptions impacting the fair value of the preferred stock tranche feature included the estimated fair value of our Series B redeemable convertible preferred stock, estimated probability of and time to liquidity for going public and staying-private, and the determination of the type of option (call option and/or forward contract) and associated probability.

We determined the estimated fair value per share of the underlying redeemable convertible preferred stock by taking into consideration the most recent sales of our redeemable convertible preferred stock as well as additional factors that we deemed relevant. We assessed these assumptions and estimates on a quarterly basis as additional information impacting the assumptions became available. The risk-free rate was determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the expected term of the preferred stock tranche feature. We estimated a 0% dividend yield based on the expected dividend yield and the fact that we have never paid or declared dividends. We estimated the time to liquidity by weighting potential timelines associated with reaching various pipeline milestones and completing an initial public offering. Historically, we have been a private company and lack company-specific and implied volatility information of our stock. Therefore, we estimated our expected stock volatility based on the historical volatility of a representative group of public companies in the biotechnology industry for the expected terms. The determination of the type of option is based on the payouts available to the holders of the tranche rights and the level of control the investors had over exercising these rights.

These estimates involved inherent uncertainties and the application of significant judgment. As a result, if factors or expected outcomes change and we used significantly different assumptions or estimates, our preferred stock tranche liability could be materially different.

Fair Value Option for Convertible Notes

We elected to account for our convertible notes at fair value in order to measure those liabilities at amounts that more accurately reflect the current economic environment in which the Company operates. We recorded the convertible notes at fair value with changes in fair value recorded in earnings at each reporting period through settlement. The fair value of the convertible notes was determined using a probability-weighted income approach as the convertible notes contained various settlement outcomes. The significant assumptions used to estimate the fair value of the convertible notes involved inherent uncertainties and the application of significant judgment, and included the time to maturity and the probability of the various settlement outcomes.

Revenue from Contracts

We recognize revenue from contracts when our customer obtains control of the promised goods or services, in an amount that reflects the consideration which we have received or expect to receive in exchange for those goods or services.

Our revenues are primarily derived through our collaborative research, development and license agreements. The terms of these types of agreements may include (i) research and development services, (ii) licenses for our technology or programs, and (iii) services or obligations in connection with participation in research or steering committees. Payments to us under these arrangements typically include one or more of the following: nonrefundable upfront and license fees, research funding, milestone and other contingent payments for the achievement of defined research, development and commercial-based events, as well as royalties on sales of any commercialized products. We assess whether the promises in its arrangements with customers are considered

318

distinct performance obligations that should be accounted for separately. Judgment may be required to determine whether the research and development services are distinct from the license to our intellectual property or participation on steering committees.

Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. If these options provide a material right to the customer, they are considered performance obligations. The identification of material rights requires judgments related to the determination of the value of the underlying license relative to the option exercise price, including assumptions about technical feasibility and the probability of developing a candidate that would be subject to the option rights.

The transaction price in each arrangement is allocated based on the relative standalone selling price (“SSP”) of each distinct performance obligation, which requires judgment. In instances where SSP is not directly observable, such as when a license or service is not sold separately, SSP is determined using information that may include market conditions and other observable inputs. Due to the early stage of our licensed technology, the license of such technology is typically combined with research and development services and steering committee participation as one performance obligation. Changes in the key assumptions used to determine the SSP could have a significant effect on the allocation of arrangement consideration between multiple performance obligations.

Recently Issued Accounting Pronouncements

See Note 2 to our consolidated financial statements included elsewhere in this proxy statement/prospectus for recently issued accounting pronouncements.

Emerging Growth Company Status

The JOBS Act permits an emerging growth company to take advantage of an extended transition to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. DYNS is an “emerging growth company” as defined in Section 2(a) of the Securities Act, and has elected to take advantage of the benefits of this extended transition period, which means that when an accounting standard is issued or revised and has different application dates for public or private companies, DYNS may adopt the new or revised standard only at the time private companies are required or permitted to adopt the new or revised standard.

Following the consummation of the Business Combination, we expect to remain an emerging growth company until the earlier of: (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of the DYNS IPO (which occurred on May 25, 2021), (b) in which we have total annual revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common equity that is held by non-affiliates exceeds $700 million as of the end of that fiscal year’s second fiscal quarter and our net sales for the year exceed $100 million; and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the preceding, rolling three-year period. As a result, following the Business Combination, our consolidated financial statements may not be comparable to the financial statements of companies that are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies.

Smaller Reporting Company Status

319

is less than $250 million as of the last business day of the second fiscal quarter, or (2) our annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter are less than $100 million and the market value of our common stock held by non-affiliates is less than $700 million as of the last business day of the second fiscal quarter.

Segment Information

We have one business activity and operate in one reportable segment.

Represents: (i) for Dr. Lee, $11,600 in matching contributions made by Senti under Senti’s 401(k) plan; and (ii) for Mr. Herberts, $11,600 in matching contributions made by Senti under Senti’s 401(k) plan and $3,745 paid by us to cover taxes Mr. Herberts owed relating to a health savings account contribution.

Narrative to the Summary Compensation Table

Senti’s compensation committee or board of directors reviews compensation annually for all employees, including named executive officers. In making compensation determinations, Senti considers compensation for comparable positions in the market, the historical compensation levels of executives, individual performance as compared to Senti’s expectations and objectives, Senti’s desire to motivate employees to achieve short- and long-term results that are in the best interests of Senti’s stockholders and a long-term commitment to the company.

Either the compensation committee or the board of directors has historically determined the executive officers’ compensation and has typically reviewed and discussed management’s proposed compensation with the chief executive officer for all executives other than the chief executive officer. Based on those discussions and its

321

discretion, either Senti’s board of directors or compensation committee then approved the compensation of each executive officer. Upon the closing of the Business Combination, the compensation committee will determine the executive officers’ compensation and follow this process, but generally the compensation committee itself, rather than the board of directors, will approve the compensation of each executive officer.

Annual Base Salary

Base salaries for the executive officers are initially established through arm’s-length negotiations at the time of the executive officer’s hiring, taking into account such executive officer’s qualifications, experience, the scope of his or her responsibilities and competitive market compensation paid by other companies for similar positions within the industry and geography. Base salaries are reviewed periodically, typically in connection with Senti’s annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. In making decisions regarding salary increases, Senti may also draw upon the experience of members of the board of directors with executives at other companies. The 2021 base salaries for the named executive officers were as follows: (a) $475,000 for Dr. Lu; (b) $410,000 for Mr. Herberts; and (c) $400,000 for Dr. Lee.

Non-Equity Incentive Plan Compensation

Senti’s named executive officers are each eligible to receive a discretionary annual bonus based on individual and company performance. In 2021, Dr. Lu was eligible to earn an annual target performance bonus equal to 50% of his 2021 base salary based on the achievement of corporate objectives. Mr. Herberts and Dr. Lee were eligible to earn an annual target performance bonus equal to 40% of their respective 2021 base salary based on the achievement of both individual and corporate objectives. Payment of 2021 annual bonuses was based in part on us achieving certain research and product development, capital raising and other target goals. The compensation committee determined that Dr. Lu, Mr. Herberts and Dr. Lee were entitled to approximately 92.3%, 92.3% and 100% respectively, of their target bonuses.

Equity-Based Incentive Awards

Senti’s equity-based incentive awards are designed to align our interests and those of Senti’s stockholders with those of Senti’s employees and consultants, including Senti’s named executive officers. As of December 31, 2021, stock option awards were the only form of equity award we granted to the named executive officers.

We have historically used stock options as incentives for long-term compensation to the named executive officers as the return on the awards is tied to an increase in our stock price. Senti may grant equity awards at such times as our board of directors or compensation committee determines appropriate in their discretion. Additional grants may occur periodically in order to incentivize executives with respect to achieving certain corporate goals or to reward them for exceptional performance.

Prior to the completion of the Business Combination, all of the equity incentive awards Senti granted were made pursuant to Senti’s 2016 Stock Incentive Plan, as amended, or the 2016 Plan. Following the completion of the Business Combination, Senti will grant equity incentive awards under the terms of our 2022 Equity Incentive Plan, or the 2022 Plan, which will become effective once the registration statement of which this proxy statement/prospectus forms a part is declared effective. The terms of Senti’s 2016 Plan are described below under “— Equity Benefit Plans.”

All stock options are granted with an exercise price per share that is no less than the fair market value of Senti’s common stock on the date of grant of such award. Senti’s stock option grants generally vest over a four-year period, and may be subject to acceleration of vesting and exercisability under certain termination and change in control events. See “— Outstanding Equity Awards at Fiscal Year-End” below for additional information.

Outstanding Equity Awards at Fiscal Year-End

The following table provides information regarding the outstanding equity awards held by the named executive officers as of December 31, 2021. All awards were granted pursuant to the 2016 Plan. See “— Equity Benefit Plans–2016 Stock Incentive Plan” below for additional information.

324

was initially entitled to an annual base salary of $350,000, a signing bonus of $126,666.67, and a discretionary annual target bonus equal to 35% of his base salary, contingent upon the achievement of performance objectives established by Senti. In January 2021, Dr. Lee’s annual base salary was increased to $400,000. Prior to his employment, starting in July 2016, Dr. Lee provided services to Senti pursuant to a consulting agreement. In connection with such consulting services, Dr. Lee was issued 3,750,000 shares of Senti common stock pursuant to a restricted stock purchase agreement, which vested as follows: 25% on the date of issuance and the remainder in 36 equal monthly installments thereafter, subject to Dr. Lee’s continued service through each such date.

Dr. Lee remains eligible for future equity awards as determined by the Combined Company’s board of directors or its compensation committee.

Potential Payments and Benefits upon Termination or Change in Control

Regardless of the manner in which a named executive officer’s employment with Senti terminates, the named executive officer is entitled to receive amounts earned during his term of service, including salary and accrued unused vacation pay.

Termination Payments and Benefits

Under the terms of their respective employment agreements, Dr. Lu, Mr. Herberts and Dr. Lee are each eligible to receive the following severance payments and benefits upon a termination without “cause” or upon “resignation for good reason,” each as defined below, contingent upon the named executive officer’s timely delivery to Senti of a satisfactory release of claims:

If such termination or resignation occurs within 3 months before or 12 months after a change of control, then all of his then remaining unvested shares of restricted common stock will become fully vested, although such restricted stock has already vested in full.

•

For the purposes of Senti’s named executive officers’ severance benefits, the following definitions apply:

•

“cause” means the occurrence of any of the following: (i) the employee’s material breach of their employment agreement; (ii) any act (other than retirement) or omission which has a material and adverse effect on our business, or on the employee’s ability to perform services for us, including the commission of any crime (other than minor traffic violations); or (iii) material misconduct or material neglect of the employee’s duties in connection with our business or affairs; provided, however, that before terminating the employee’s employment for cause, we will: (a) provide them with 30 days’ advance written notice with the event specifically set forth in the notice and the opportunity to cure the event (if curable); (b) provide them with a reasonable opportunity to present their case to our board of directors; and (c) require that to our board of directors determine, by majority vote, whether their employment should be terminated for cause.

325

“change of control” means the closing of: (i) a sale of all or substantially all of our assets; (ii) any consolidation or merger by us with or into any other corporation or other entity or person, or any other corporate reorganization, other than any such consolidation, merger or reorganization in which our stockholders immediately prior to such consolidation, merger or reorganization, continue to hold a majority of the voting power of the surviving entity (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such consolidation, merger or reorganization; or (iii) a stock tender or a merger, consolidation or similar event pursuant to a transaction or series of related transactions in which a third party (which term shall include a current stockholder) acquires more than fifty percent (50%) of our equity voting securities outstanding immediately prior to the consummation of such transaction or series of related transactions, and our stockholders do not retain a majority of the equity voting securities of the surviving entity, other than (a) a merger, conversion or other transaction the principal goal of which is to change our jurisdiction of incorporation, or (b) an equity security financing for our account in which our capital stock is sold to one or more institutional investors.

•

“good reason” means the employee’s termination of their own employment because of any of the following: (i) our breach of any one or more of the material provisions of this Agreement; (ii) a material reduction by us of their annual base salary, unless they consent to such reduction or unless such reduction is applied equally, as a percentage of base salary, to all our senior executives; (iii) a relocation of our location such that their one-way commute as of the effective date of their employment agreement increases by more than 35 miles; or (iv) a material adverse change in their duties, authority, or responsibilities relative to their duties, authority, or responsibilities in effect immediately prior to such reduction (other than a change in title and provided that a change in title, reporting lines or position in connection with a change of control will not, in itself, be deemed to be a change in duties, authority or responsibility); provided, however, that any such termination by them shall only be deemed for good reason pursuant to this definition if: (a) they give us written notice of their intent to terminate for good reason within 90 days following the first occurrence of the condition that they believe constitutes good reason, which notice shall describe such condition; (b) we fail to remedy such condition within 30 days following receipt of the written notice (referred to as the cure period); and (c) they voluntarily terminate their employment within 30 days following the end of the cure period.

Health and Welfare and Retirement Benefits; Perquisites

Health and Welfare Benefits and Perquisites

All of Senti’s current named executive officers are eligible to participate in Senti’s employee benefit plans, including Senti’s medical, dental, vision, disability and life insurance plans, in each case on the same basis as all of Senti’s other employees. Senti pays the premiums for the life, disability and accidental death and dismemberment insurance for all of its employees, including its named executive officers. Senti generally does not provide perquisites or personal benefits to its named executive officers, except in limited circumstances.

401(k) Plan

Senti currently maintains a 401(k) retirement savings plan for its employees, including its named executive officers, who satisfy certain eligibility requirements. The 401(k) plan is intended to qualify as a tax-qualified plan under the Code. Senti’s named executive officers are eligible to participate in the 401(k) plan on the same basis as its other employees. The Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Senti currently provides matching 401(k) contributions to its named executive officers.

Equity Benefit Plans

2016 Stock Incentive Plan

Senti’s board of directors adopted, and Senti’s stockholders approved the 2016 Stock Incentive Plan, or the 2016 Plan, in July 2016. As of December 31, 2021, under the 2016 Plan, options to purchase 57,732,604 shares

326

of common stock were outstanding, and 3,648,364 shares of common stock remained available for future issuance.

Awards. The 2016 Plan provides for the grant of ISOs to employees of Senti, any parent or certain subsidiary companies, and for the grant of NSOs and restricted shares to such employees, Senti’s directors, and to consultants engaged by Senti or any of its subsidiary companies.

Plan Administration. Senti’s board of directors administers and interprets the provisions of the 2016 Plan. Senti’s board of directors may delegate any or all its powers under the 2016 Plan to a committee appointed by the Board (to the extent permitted under applicable law and regulations), except that the Board retains control to amend or terminate the plan and to determine share issuances pursuant to the terms of the 2016 Plan. Under the 2016 Plan, Senti’s board of directors (or a committee delegated by Senti’s board of directors) has the authority to construe terms of awards granted under the 2016 Plan and to prescribe, amend and rescind rules and regulations relating to the 2016 Plan, to determine the terms and provisions of awards granted under the 2016 Plan and to make all other determinations in the judgment of the Senti board of directors necessary or desirable for the administration of the 2016 Plan.

Stock Options and Restricted Shares. Stock options and restricted shares granted under the 2016 Plan generally have terms similar to those described above with respect to stock options and restricted shares granted under the 2022 Plan, except the 2016 Plan provides that (unless otherwise provided for in a stock option agreement) stock options may be exercised for a period of 12 months in the case of an optionee’s death or permanent and total disability.

Changes to Capital Structure. If, through or as a result of Senti’s merger, consolidation, sale of all or substantially all of our assets, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar transaction, (i) the outstanding shares of common stock are increased, decreased or exchanged for a different number or kind of shares or other securities of Senti, or (ii) additional shares or new or different or other securities of Senti or other noncash assets are distributed with respect to such shares of Senti common stock or other securities, an appropriate and proportionate adjustment shall be made in (x) the maximum number and kind of shares reserved for issuance under the 2016 Plan, (y) the number and kind of shares or other securities subject to any then outstanding stock options, and (z) the price for each share or other security subject to any then outstanding stock options, so that upon exercise of such stock options, in lieu of the share of common stock for which such options were then exercisable, the relevant optionee shall be entitled to receive, for the same aggregate consideration, the same total number and kind of shares or other securities, cash or property that the owner of an equal number of outstanding shares of common stock immediately prior to the event requiring adjustment would own as a result of the event.

Corporate Transactions. If Senti is merged with or into or consolidated with another corporation under circumstances where Senti stockholders immediately prior to such merger or consolidation do not own after such merger or consolidation shares representing at least fifty percent (50%) of the voting power of Senti or the surviving or resulting corporation, as the case may be, or if shares representing fifty percent (50%) or more of the voting power of Senti are transferred to an unrelated third party, as hereinafter defined, or if Senti is liquidated, or sells or otherwise disposes of all or substantially all of its assets (each such transaction is referred to as a “change in control transaction”), Senti’s board of directors, or the board of directors of any corporation assuming the obligations of Senti, may, in its discretion, take any one or more of the following actions, as to some or all outstanding stock options or restricted stock awards (and need not take the same action as to each such option or restricted stock award): (i) provide that such stock options shall be assumed, or equivalent stock options will be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), provided that any such stock options substituted for incentive stock options shall meet the requirements of Section 424(a) of the Code, (ii) upon written notice to the optionees, provide that all unexercised stock options (whether vested or unvested) will terminate immediately prior to the consummation of the change in control transaction unless exercised by the optionee to the extent otherwise then exercisable within a specified period following the date of such notice,

327

(iii) upon written notice to the grantees, provide that all unvested shares of restricted stock shall be repurchased at cost, (iv) make or provide for a cash payment to the optionees equal to the difference between (A) the fair market value of the per share consideration (whether cash, securities or other property or any combination of the above) the holder of a share of common stock will receive upon consummation of the change in control transaction (the “per share transaction price”) times the number of shares of common stock subject to outstanding vested stock options (to the extent then exercisable at prices not equal to or in excess of the per share transaction price) and (B) the aggregate exercise price of such outstanding vested stock options, in exchange for the termination of such stock options, or (v) provide that all or any outstanding stock options shall become exercisable and all or any outstanding restricted stock awards shall vest in part or in full immediately prior to such event. To the extent that any stock options are exercisable at a price equal to or in excess of the per share transaction price, the Senti board of directors may provide that such stock options shall terminate immediately upon the consummation of the change in control transaction without any payment being made to the holders of such stock options.

328

BENEFICIAL OWNERSHIP

The following table and accompanying footnotes set forth information regarding the (1) actual beneficial ownership of shares of DYNS Common Stock as the Record Date, and (2) expected beneficial ownership of shares of New Senti common stock immediately following the consummation of the Business Combination (assuming a “no redemption” scenario and assuming a “maximum redemption scenario” as described below) by:

•

DYNS’s current executive officers and directors;

•

each person who is expected to become one of the executive officers or directors of New Senti following the Business Combination, assuming the Director Election Proposal is approved;

•

all of DYNS’ current executive officers and directors as a group, and all of the executive officers and directors of New Senti, assuming the Director Election Proposal is approved, as a group; and

•

each person who is known to be the beneficial owner of more than 5% of the outstanding DYNS Common Stock or is expected to be the beneficial owner of more than 5% of shares of New Senti common stock following the Business Combination.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC. A person is a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of the security, or “investment power,” which includes the power to dispose of or to direct the disposition of the security, or has the right to acquire such powers within 60 days.

The beneficial ownership of shares of DYNS Common Stock prior to the Business Combination is calculated based on 29,465,500 shares of DYNS Common Stock (consisting of 23,715,500 shares of Class A Common Stock and 5,750,000 shares of Class B Common Stock) issued and outstanding as of the Record Date. For purposes of the table below, voting power represents the combined voting power of Class A Common Stock and Class B Common Stock owned beneficially by such person and, on all matters to be voted upon, the holders of the Class A Common Stock and the Class B Common Stock vote together as a single class. Currently, all of the Class B Common Stock are convertible into Class A Common Stock on a one-for-one basis.

The expected beneficial ownership of shares of New Senti common stock following the Business Combination is calculated based on 59,258,389 shares (assuming no redemptions) of New Senti common stock expected to be outstanding immediately following consummation of the Business Combination and assumes an exchange ratio for converting each share of Senti preferred stock and/or Senti common stock into shares of New Senti Common Stock of 0.1955. Such expected number of shares of New Senti Common Stock outstanding amount includes shares that are expected to be issued in connection with the PIPE Investment.

The expected beneficial ownership of shares of New Senti Common Stock following the Business Combination also assumes two redemption scenarios as follows:

•

Assuming No Redemptions (Scenario 1): This presentation assumes that no Public Stockholders exercise their right to redeem their Public Shares for their pro rata share of the Trust Account, and thus, the full amount held in the Trust Account as of the Closing is available for the Business Combination; and

•

329

Senti will waive this condition prior to Closing, however there is no guarantee that it would and, if it did not, the Business Combination would not be consummated. When considering this maximum redemptions scenario, you should consider that the Anchor Investors’ commitments under the Non-Redemption Agreements not to redeem or to transfer their shares of Class A Common Stock do not apply in circumstances where they are compelled to do so in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. If one or more Anchor Investors was compelled to transfer shares of Class A Common Stock for this reason, it is possible that more than 15,031,517 Public Shares could be redeemed and that there may be less than approximately $146.5 million in cash available at Closing. The redemption of more than 15,031,517 Public Shares would change some of the figures presented in the maximum redemptions scenario in the unaudited pro forma financial data which follows.

Unless otherwise noted in the footnotes to the following table, and subject to applicable community property laws, the persons and entities named in the table have sole voting and investment power with respect to their beneficially owned common stock.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policies and Procedures for Related Party Transactions

DYNS’s Code of Ethics requires DYNS to avoid, wherever possible, all conflicts of interests, except under guidelines or resolutions approved by the Board (or the appropriate committee of the Board) or as disclosed in DYNS’s public filings with the SEC. Under DYNS’s Code of Ethics, conflict of interest situations will include any financial transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) involving the company. Additionally, DYNS’s related party transaction policy sets forth the policies and procedures for the review and approval or ratification of related party transactions. This policy covers any transaction, arrangement or relationship or any series of similar transactions, arrangements or relationships, in which DYNS is a participant and a related party had or will have a direct or indirect material interest, as determined by the audit committee of DYNS’s Board, including, without limitation, purchases of goods or services by or from the related party or entities in which the related party has a material interest, and indebtedness, guarantees of indebtedness or employment by DYNS of a related party. These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee or officer.

DYNS’s audit committee, pursuant to its written charter, is responsible for reviewing and approving related party transactions to the extent that DYNS enters into such transactions. An affirmative vote of a majority of the members of the audit committee present at a meeting at which a quorum is present is required in order to approve a related party transaction. A majority of the members of the entire audit committee constitute a quorum. Without a meeting, the unanimous written consent of all of the members of the audit committee is required to approve a related party transaction.

DYNS Related Party Transactions

Founder Shares

On March 8, 2021, the Sponsor was issued 5,750,000 shares of Class B Common Stock (the Founder Shares) for an aggregate price of $25,000. The Founder Shares included an aggregate of up to 750,000 shares of Class B Common Stock subject to forfeiture by the Sponsor to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the Sponsor would own, on an as-converted basis, 20% of our issued and outstanding shares after our Initial Public Offering (excluding the Private Placement Shares) and assuming our Sponsor did not purchase any Public Shares in our Initial Public Offering). The underwriter fully exercised the over-allotment option on May 28, 2021; thus, these 750,000 Founder Shares are no longer subject to forfeiture.

Private Placement Shares

Simultaneously with the closing of our Initial Public Offering, we consummated the sale of 715,500 shares of Class A Common Stock (the “Private Placement Shares”) at a price of $10.00 per share in a private placement to our Sponsor, generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares was added to the net proceeds from our Initial Public Offering held in the Trust Account. If we do not complete an initial business combination within 24 months from the closing of our Initial Public Offering, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of Public Shares (subject to the requirements of applicable law).

Promissory Note – Related Party

333

the consummation of our Initial Public Offering. In April 2021, the Company borrowed $250,000 under the Promissory Note, which was repaid on May 26, 2021.

Administrative Support Agreement

We entered into an agreement, commencing on the effective date of our Initial Public Offering, to pay the Sponsor up to a total of $10,000 per month for office space, administrative and support services. Upon the completion of an initial business combination, the agreement will terminate. To date, we have not exercised our option to use such services and have not paid any fees to the Sponsor.

Related Party Loans

In addition, in order to finance transactions costs in connection with a business combination, the Sponsor, or certain of the Company’s officers, directors, or their affiliates may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a business combination, the Company will repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a business combination is not completed, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such Working Capital Loans may be converted into shares at a price of $10.00 per share at the option of the lender. The shares would be identical to the Private Placement Shares.

Sponsor Support Agreement

In connection with the execution of the Business Combination Agreement, the Sponsor and each of our officers and directors entered into the Sponsor Support Agreement with DYNS and Senti. Under the Sponsor Support Agreement, the Sponsor has agreed to vote, at any meeting of the stockholders of DYNS and in any action by written consent of the stockholders of DYNS, all of its shares of Class B Common Stock (together with any other equity securities of DYNS that it holds of record or beneficially, as of the date of the Sponsor Support Agreement, or of which it acquires record or beneficial ownership after the date thereof (the “Subject DYNS Equity Securities”)) (i) in favor of (a) the Business Combination Agreement and the transactions contemplated thereby and (b) the other proposals that DYNS and Senti agreed in the Business Combination Agreement shall be submitted at such meeting for approval by DYNS’s stockholders together with the proposal to obtain the DYNS stockholders’ approval for the Business Combination (the “Required Transaction Proposals”) and (ii) against any proposal that conflicts or materially impedes or interferes with any Required Transaction Proposals or that would adversely affect or delay the Business Combination. The Sponsor Support Agreement also prohibits the Sponsor from, among other things and subject to certain exceptions, selling, assigning or transferring any Subject DYNS Equity Securities held by the Sponsor or taking any action that would have the effect of preventing or materially delaying the Sponsor from performing its obligations under the Sponsor Support Agreement. In addition, in the Sponsor Support Agreement, the Sponsor agrees to waive, and not to assert or perfect, among other things, any rights to adjustment or other anti-dilution protections with respect to the rate at which the shares of Class B Common Stock held by the Sponsor convert into shares of Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement.

Commitments and Contingencies

Registration Rights

The holders of the Founder Shares, Private Placement Shares (and any Class A Common Stock that may be issued upon conversion of Working Capital Loans) will be entitled to registration rights pursuant to the

334

registration and stockholder rights agreement requiring us to register such securities for resale (in the case of the Founder Shares, only after conversion to our Class A Common Stock). As at the date of this proxy statement/prospectus, there are 5,750,000 Founder Shares and 715,500 Private Placement Shares outstanding, however, pursuant to the Non-Redemption Agreements, if the Business Combination is consummated, the Sponsor anticipates that it will forfeit 885,377 Founder Shares, leaving it with 4,864,623 Founder Shares immediately after Closing. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of an initial business combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. The registration rights agreement does not contain liquidated damages or other cash settlement provisions resulting from delays in registering our securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

The IRA provides the holders of Senti redeemable convertible preferred stock with certain registration rights, including the right to demand that Senti file a registration statement or request that their shares be covered by a registration statement that Senti is otherwise filing. In addition, the IRA also grants a right of first offer with respect to future sales of Senti equity, as well as certain information and inspection rights to each holder who holds at least 2,815,507 shares of Senti redeemable convertible preferred stock, which rights will terminate on the closing of the Business Combination. In connection with the closing of the Business Combination, the holders of up to 99,734,543 shares of Senti common stock issuable on conversion of outstanding redeemable convertible preferred stock will be entitled to rights with respect to the registration of their shares under the Securities Act under the Investors’ Rights Agreement filed as Exhibit 10.18 hereto and incorporated herein by reference, which will supersede and replace the IRA.

BlueRock is a wholly-owned subsidiary of Bayer Healthcare LLC, a holder of more than 5% of Senti’s common stock.

Indemnification Agreements

The Proposed Charter will contain provisions limiting the liability of directors, and the amended and restated bylaws will provide that we will indemnify each of New Senti’s directors and officers to the fullest extent permitted under Delaware law. The Proposed Charter and amended and restated bylaws will also provide our board of directors with discretion to indemnify our employees and other agents when determined appropriate by the board.

In addition, Senti has entered into or intends to enter into an indemnification agreement with each of its directors and executive officers, which will require Senti to indemnify them. For more information regarding these agreements, see the section titled “Executive Compensation—Limitations of Liability and Indemnification Matters.”

Stock Option Grants to Directors and Executive Officers

Senti has granted stock options to its directors and executive officers, as more fully described in the sections titled “Executive Compensation” and “Management—Non-Employee Director Compensation.”

Related Person Transactions Policy Following the Business Combination

Upon consummation of the Business Combination, it is anticipated that the Combined Company’s board of directors will adopt a related person transaction policy setting forth the policies and procedures for the identification, review and approval or ratification of related person transactions. This policy covers, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which the Combined Company and a related person were or will be participants and the amount involved exceeds $120,000, including purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness and guarantees of indebtedness. In reviewing and approving or rejecting any such transactions, the Combined Company’s audit committee will consider all relevant facts and circumstances as appropriate, such as the purpose of the transaction, the availability of other sources of comparable products or services, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction, management’s recommendation with respect to the proposed related person transaction, and the extent of the related person’s interest in the transaction.

339

DESCRIPTION OF NEW SENTI’S SECURITIES AFTER THE BUSINESS COMBINATION

As a result of the Business Combination, DYNS stockholders who have or receive shares of Class A Common Stock will become the stockholders of the Combined Company. Your rights as the Combined Company stockholders will be governed by Delaware law and the Proposed Charter, if approved, and DYNS’s bylaws. The following description of the material terms of the Combined Company’s securities reflects the anticipated state of affairs upon completion of the Business Combination.

In connection with the Business Combination, DYNS will amend and restate the Current Charter. The following summary of the material terms the Combined Company’s securities following the Business Combination is not intended to be a complete summary of the rights and preferences of such securities. The full text of the Proposed Charter is attached as Annex B to this proxy statement/prospectus. You are encouraged to read the applicable provisions of Delaware law, the Proposed Charter and the bylaws in their entirety for a complete description of the rights and preferences of the Combined Company securities following the Business Combination.

Authorized and Outstanding Stock

The Proposed Charter authorizes the issuance of 510,000,000 shares, consisting of 500,000,000 shares of common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.0001 par value. As of the Record Date, there were 23,715,500 shares of Class A Common Stock and 5,750,000 shares of Class B Common Stock outstanding. In connection with the Business Combination and subject to the terms of the Current Charter, all shares of outstanding Class B Common Stock will automatically be converted into shares of Class A Common Stock. No shares of preferred stock are currently outstanding.

Common Stock

The Proposed Charter, which DYNS will adopt if the Charter Amendment Proposal is approved, provides the following with respect to the rights, powers, preferences and privileges of the New Senti Common Stock.

Voting Power

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of New Senti Common Stock possess all voting power for the election of the Combined Company’s directors and all other matters requiring stockholder action. Holders of New Senti Common Stock are entitled to one vote per share on matters to be voted on by stockholders.

Dividends

Holders of New Senti Common Stock will be entitled to receive such dividends, if any, as may be declared from time to time by the Combined Company’s board of directors in its discretion out of funds legally available therefor. DYNS has not historically paid any cash dividends on its Class A Common Stock or Class B Common Stock to date and does not intend to pay cash dividends in the foreseeable future. Any payment of cash dividends in the future will be dependent upon New Senti’s revenues and earnings, if any, capital requirements and general financial conditions. In no event will any stock dividends or stock splits or combinations of stock be declared or made on New Senti Common Stock unless the shares of New Senti Common Stock at the time outstanding are treated equally and identically.

Liquidation, Dissolution and Winding Up

In the event of the Combined Company’s voluntary or involuntary liquidation, dissolution or winding-up, the net assets of New Senti will be distributed pro rata to the holders of New Senti Common Stock, subject to the rights of the holders of the preferred stock, if any.

340

Preemptive or Other Rights

There are no sinking fund provisions applicable to the New Senti Common Stock.

Preferred Stock

The Proposed Charter provides that shares of preferred stock may be issued from time to time in one or more series. New Senti’s board of directors will be authorized to fix designations, powers, including voting powers, full or limited, or no voting powers, preferences and the relative, participating, optional or other special rights of the shares of each series of preferred stock and any qualifications, limitations and restrictions thereof. New Senti’s board of directors will be able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the New Senti Common Stock and could have anti-takeover effects. The ability of New Senti’s board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control of New Senti or the removal of existing management. DYNS has no preferred stock currently outstanding.

Registration Rights

DYNS, certain of the Senti stockholders and certain of the DYNS stockholders will enter into the Investor Rights Agreement, pursuant to which, among other things, such stockholders will be granted certain registration rights with respect to certain shares of securities held by them. A copy of the form of the Investor Rights Agreement is attached as Exhibit 10.19 hereto and incorporated herein by reference.

Anti-Takeover Provisions

Proposed Charter and Bylaws

Among other things, the Proposed Charter and bylaws (as amended from time to time) will:

•

permit the Combined Company’s board of directors to issue up to 10,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate, including the right to approve an acquisition or other change of control;

•

provide that the number of directors of the Combined Company may be changed only by resolution of the Combined Company’s board of directors;

•

provide that, subject to the rights of any series of preferred stock to elect directors, directors may be removed only with cause by the holders of at least 75% of all of the Combined Company’s then-outstanding shares of the capital stock entitled to vote generally at an election of directors;

•

provide that all vacancies, subject to the rights of any series of preferred stock, including newly created directorships, may, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

•

provide that stockholders seeking to present proposals before a meeting of stockholders or to nominate candidates for election as directors at a meeting of stockholders must provide advance notice in writing, and also specify requirements as to the form and content of a stockholder’s notice;

•

provide that special meetings of the Combined Company’s stockholders may be called the Combined Company’s board of directors pursuant to a resolution adopted by a majority of the board;

•

provide that the Combined Company’s board of directors will be divided into three classes of directors, with the directors serving three-year terms (see the section titled “Management of the Combined Company”), therefore making it more difficult for stockholders to change the composition of the board of directors; and

341

•

not provide for cumulative voting rights, therefore allowing the holders of a majority of the shares of New Senti Common Stock entitled to vote in any election of directors to elect all of the directors standing for election, if they should so choose.

The combination of these provisions will make it more difficult for the existing stockholders to replace the Combined Company’s board of directors as well as for another party to obtain control of the Combined Company by replacing the Combined Company’s board of directors. Because the Combined Company’s board of directors will have the power to retain and discharge its officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock will make it possible for the Combined Company’s board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change the control of the Combined Company.

These provisions are intended to enhance the likelihood of continued stability in the composition of the Combined Company’s board of directors and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce the Combined Company’s vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for the Combined Company’s shares and may have the effect of delaying changes in our control or management. As a consequence, these provisions may also inhibit fluctuations in the market price of the Combined Company’s stock.

Certain Anti-Takeover Provisions of Delaware Law

DYNS is currently subject to the provisions of Section 203 of the DGCL and the Combined Company will also be subject to these provisions. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

•

a stockholder who owns 15% or more of our outstanding voting stock (otherwise known as an “interested stockholder”);

•

an affiliate of an interested stockholder; or

•

an associate of an interested stockholder, for three years following the date that the stockholder became an interested stockholder.

A “business combination” includes a merger or sale of more than 10% of a corporation’s assets. However, the above provisions of Section 203 would not apply if:

•

the relevant board of directors approves the transaction that made the stockholder an “interested stockholder,” prior to the date of the transaction;

•

after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least 85% of the corporation’s voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or

•

on or subsequent to the date of the transaction, the initial business combination is approved by the board of directors and authorized at a meeting of the corporation’s stockholders, and not by written consent, by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

These provisions may have the effect of delaying, deferring, or preventing changes in control of the Combined Company.

342

SECURITIES ACT RESTRICTIONS ON RESALE OF COMMON STOCK

Rule 144

Pursuant to Rule 144, a person who has beneficially owned restricted shares for at least six months would be entitled to sell their securities provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

Persons who have beneficially owned restricted shares for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

•

1% of the total number of ordinary shares then outstanding; or

•

the average weekly reported trading volume of the Class A Common Stock during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

•

the issuer of the securities that was formerly a shell company has ceased to be a shell company;

•

the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

•

the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Current Reports on Form 8-K; and

•

at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

As a result, our initial stockholders will be able to sell their Founder Shares pursuant to Rule 144 without registration one year after we have completed our initial business combination.

COMPARISON OF GOVERNANCE AND STOCKHOLDERS’ RIGHTS

General

DYNS is incorporated under the laws of the State of Delaware and the rights of DYNS stockholders are governed by the laws of the State of Delaware, including the DGCL, the Current Charter and DYNS’s bylaws. In connection with the Business Combination, DYNS stockholders will vote on the Proposed Charter, which (if approved) will become effective as of the Closing. DYNS, subsequent to the Business Combination, is referred to as New Senti. Following the Business Combination, the rights of DYNS stockholders will continue to be governed by Delaware law but will no longer be governed by the Current Charter and instead will be governed by the Proposed Charter (if approved).

343

Comparison of Governance and Stockholders’ Rights

Set forth below is a summary comparison of material differences between the rights of DYNS stockholders under the Current Charter and the bylaws (left column) and under the Proposed Charter and the bylaws (right column).

Board Composition

The Combined Company’s board of directors will manage the business and affairs of the Combined Company, as provided by Delaware law, and will conduct its business through meetings of the board of directors and its standing committees. Assuming the election of the nominees set forth in “Proposal 5: The Director Election Proposal,” it is anticipated that, upon the consummation of the Business Combination, the Combined Company’s board of directors will consist of seven members, four of whom will be designated by Senti, two of whom will be designated by the Sponsor and one of whom will be designated by Senti and DYNS (on behalf of the Sponsor). The primary responsibilities of the Combined Company’s board of directors will be to provide risk oversight and strategic guidance to the Combined Company and to counsel and direct the Combined Company’s management. The Combined Company’s board of directors will meet on a regular basis and will convene additional meetings, as required.

Director Independence

As a result of its common stock continuing to be listed on Nasdaq following consummation of the Business Combination, the Combined Company will adhere to the rules of Nasdaq in determining whether a director is independent.The Board has consulted, and the Combined Company’s board of directors will consult, with its counsel to ensure that the board of directors’ determinations are consistent with those rules and all relevant securities and other laws and regulations regarding the independence of directors. The Nasdaq listing standards generally define an “independent director” as a person who is not an executive officer or employee, or who does not have a relationship which, in the opinion of the company’s board of directors, would interfere with the exercise of independent judgment in carrying out his or her responsibilities as a director. The parties have determined that Brenda Cooperstone, Susan Berland, Edward Mathers, Omid Farokhzad, David Epstein and James J. (Jim) Collins will be considered independent directors of the Combined Company. The Combined Company’s independent directors will have regularly scheduled meetings at which only independent directors are present.

As more fully described in Note 1 to the financial statements, the Company’s business plan is dependent on the completion of a business combination and the Company’s cash and working capital as of December 31, 2021 are not sufficient to complete its planned activities. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Dynamics Special Purpose Corp. (the “Company”) is a blank check company incorporated in Delaware on March 1, 2021. As used herein, “the Company” refers to Dynamics Special Purpose Corp. and its wholly-owned andcontrolled subsidiary, Explore Merger Sub, Inc. (“Merger Sub”), unless the context indicates otherwise. The Company was formed for the purpose of entering into a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of December 31, 2021, the Company had not commenced any operations. All activity for the period from March 1, 2021 (inception) through December 31, 2021 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below, and identifying a target company for a Business Combination and negotiating and entering into binding agreements in respect of such Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generatenon-operatingincome in the form of interest income on the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Initial Public Offering was declared effective on May 25, 2021. On May 28, 2021, the Company consummated the Initial Public Offering of 23,000,000 shares of Class A common stock (the “Public Shares”), including 3,000,000 shares of Class A common stock that were issued pursuant to the underwriter’s exercise ofitsover-allotment option in full, at $10.00 per Public Share, generating gross proceeds of $230,000,000, which is discussed in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 715,500 shares of Class A common stock (the “Private Placement Shares”) at a price of $10.00 per Private Placement Share in a private placement to Dynamics Sponsor LLC (the “Sponsor”), generating gross proceeds of $7,155,000, which is described in Note 4.

Transaction costs for the Initial Public Offering amounted to $13,198,430 consisting of $4,600,000 of underwriting fees, $8,050,000 of deferred underwriting fees, and $548,430 of other offering costs. Subsequent to the Initial Public Offering, the underwriter agreed on December 17, 2021 to waive $1,000,000 of its deferred underwriting fees of $8,050,000, thereby reducing those fees to $7,050,000; thus, the transaction costs related to our Initial Public Offering amounted to $12,198,430.

Following the closing of the Initial Public Offering on May 28, 2021, an amount of $230,000,000 ($10.00 per Public Share) from the net proceeds of the sale of the Public Shares in the Initial Public Offering and the sale of the Private Placement Shares was placed in a trust account (the “Trust Account”), and will be invested only in U.S. government securities with maturities of 185 days or less,or in money market funds meeting certain conditions under Rule2a-7under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of a Business Combination,and (ii) the distribution of the funds held in the Trust Account, as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must

DYNAMICS SPECIAL PURPOSE CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2021

complete a Business Combination with one or more target businesses that together have an aggregate fair market value of at least 80% of the value of the Trust Account (excluding the deferred underwritingfeesand taxes payable on income earned on the Trust Account) at the time of the agreement to enter into an initial Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

The Company will provide its stockholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, subject to applicable law and stock exchange listing requirements. The stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount held in the Trust Account (initially anticipated to be $10.00 per share), calculated as of two business days prior to the completion of a Business Combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations.

The Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon consummation of such Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its amended and restated certificate of incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents with the SEC prior to completing a Business Combination. If the Company seeks stockholder approval in connection with a Business Combination, the holders of the Founder Shares (as defined in Note 5) have agreed to vote their Founder Shares, Private Placement Shares and any Public Shares purchased in or after the Initial Public Offering in favor of approving a Business Combination and to waive their redemption rights with respect to any such shares in connection with a stockholder vote to approve a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares without voting, and if they do vote, irrespective of whether they vote for or against the proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

The initial stockholders have agreed to waive (a) their redemption rights with respect to any Founder Shares, Private Placement Shares and Public Shares they hold in connection with the completion of an initial Business Combination, (b) their redemption rights with respect to any Founder Shares, Private Placement Shares and Public Shares they hold in connection with a stockholder vote to approve an amendment to the Amended and Restated Certificate of Incorporation to modify the substance or timing of the Company’s obligation to allow redemption in connection with an initial Business Combination or to redeem 100%of the Public Shares if the Company has not consummated an initial Business Combination within 24months from the closing of the Initial

Public Offering or with respect to any material provision relating to the rights of holders of Public Shares, and (c) their rights to liquidating distributions from the Trust Account with respect to any Founder Shares and Private Placement Shares they hold if the Company fails to complete an initial Business Combination within 24 months from the closing of the Initial Public Offering. However, if the initial stockholders acquire Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period (as defined below).

The Company will have until May 28, 2023 to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, subject to lawfully available funds therefor, redeem the Public Shares at aper-shareprice, payable in cash, equal to the aggregate amount then on deposit in the Trust Account,including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income taxes (less up to $100,000 ofinterest to pay dissolution expenses), divided by the number of then-outstanding Public Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The underwriter has agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Public Share ($10.00).

In order to protect the amounts in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per Public Share, or (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than$10.00per Public Share due to reductions in the value of the Trust Account assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable), nor will it apply to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Business Combination Agreement

On February 12, 2022, following the period to which these consolidated financial statements relate, the Business Combination Agreement was amended by the parties thereto to reflect, among other things, (i) a correction to section 5.7 of the Business Combination Agreement, and (ii) changes to the options Senti granted to certain persons at the time the Business Combination Agreement was signed.

Other Agreements

The Business Combination Agreement contemplates the execution of various additional agreements and instruments, on or before the Closing, including, among others, the following:

Sponsor Support Agreement

In connection with the execution of the Business Combination Agreement, the Sponsor, as the sole holder of the Company’s Class B common stock, par value$0.0001per share (the “Class B Common Stock”, and also referred to herein as the Founder Shares (as defined in Note 5)) and other persons party thereto (“Other Company Insiders,” and together with the Sponsor, collectively, the “Company Insiders”), entered into a support agreement with the Company and Senti (the “Sponsor Support Agreement”). Under the Sponsor Support Agreement, the Sponsor agreed to vote, at any meeting of the stockholders of the Company and in any action by written consent of the stockholders of the Company, all of such Sponsor’s Class A Common Stock and Class B Common Stock (i) in favor of (a) the Business Combination Agreement and the transactions contemplated thereby, and (b) the other proposals that the Company and Senti agreed in the Business Combination Agreement shall be submitted at such meeting for approval by the Company’s stockholders together with the proposal to obtain the Company Stockholder Approval (together with the Company Stockholder Approval, these proposals are the Required Transaction Proposals (as defined in the Business Combination Agreement)), and (ii) against any proposal that conflicts with, or materially impedes or interferes with, any such proposal or that would adversely affect or delay the Merger. The Sponsor Support Agreement also prohibits the Sponsor from, among other things and subject to certain exceptions, selling, assigning or transferring any Class A Common Stock or Class B Common Stock held by the Sponsor prior to the Closing or taking any action that would have the effect of preventing or materially delaying the Sponsor from performing its obligations under the Sponsor Support Agreement. In addition, in the Sponsor Support Agreement, the Sponsor agreed to waive, and not to assert or perfect, among other things, any rights to adjustment or other anti-dilution protections with respect to the rate at which the shares of Class B Common Stock held by the Sponsor convert into shares of Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement.

DYNAMICS SPECIAL PURPOSE CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2021

The Sponsor Support Agreement also includes a lock-up in respect of the Sponsor’s equity interests in the Company.

Under the Senti Support Agreements, each Senti Supporting Stockholder agreed, within forty-eight hoursfollowing the effectiveness of the Registration Statement, to execute and deliver a written consent with respect to all outstanding shares of Senti common stock and preferred stock held by such Senti Supporting Stockholder (the “Subject Senti Shares”) approving the Business Combination Agreement and the transactions contemplated thereby. In addition to the foregoing, each Senti Supporting Stockholder agreed that, at any meeting of the holders of Senti capital stock, each such Senti Supporting Stockholder will appear at the meeting, in person or by proxy, and cause its Subject Senti Shares to be voted (i) to approve and adopt the Business Combination Agreement, the transactions contemplated thereby, and any other matters necessary or reasonably requested by Senti for consummation of the Merger, and (ii) against any proposal that conflicts or materially impedes or interferes with, or would adversely affect or delay, the consummation of the transactions contemplated by the Business Combination Agreement.

The Senti Support Agreement also prohibits the Senti Supporting Stockholders from, among other things, (i) transferring any of the Subject Senti Shares prior to the Closing, (ii) entering into (a) any option, commitment or other arrangement that would require the Senti Supporting Stockholders to transfer the Subject Senti Shares, or (b) any voting trust, proxy or other contract with respect to the voting of the Subject Senti Shares, or (iii) taking any action in furtherance of the foregoing. In addition, under the Senti Support Agreement, each Senti Supporting Stockholder agreed (i) not to exercise any rights of appraisal or dissenter’s rights relating to the Business Combination Agreement and the transactions contemplated thereby, and (ii) not to commence or participate in any claim or action against Senti, the Company or any of their affiliates relating to the negotiation, execution or delivery of the Senti Support Agreement or the Business Combination Agreement or the consummation of the Merger.

Additionally, (i) certain Senti Support Agreements prohibit the applicable Senti Supporting Stockholders from transferring the shares of Class A Common Stock which they will receive in the Merger for, subject to certain permitted transfers, up to 18months following the Closing, which may be reducedto 12months upon the meeting of certain criteria (such period, the “ExtendedLock-Up”),and (ii) certain other Senti Support Agreements prohibit the applicable Senti Supporting Stockholders from transferring the shares of Class A Common Stock which they will receive in the Merger for, subject to certain permitted transfers,12months following the Closing (such period, the “GeneralLock-Up”);provided that, (a) with respect to the ExtendedLock-Up,if the last reported sale price of the Class A Common Stock on Nasdaq, or any other national securities exchange on which the Class A Common Stock is then traded, is greater than or equal to$12.00per share over any20trading days within any consecutive 30trading day commencing at least330days after the Closing Date, then the ExtendedLock-Upshall be deemed to have expired with respect to each stockholder’s Class A Common Stock subject to that lock-up,

On February 12, 2022, following the period to which these consolidated financial statements relate, the Company entered into amendments to certain Senti Support Agreements to amend those agreements such that, among other things, the shares of Class A Common Stock of the relevant Senti Supporting Stockholders may not be transferred, subject to certain permitted transfers, for three years following the Closing (such period, “the Three Year Lock-Up”). Unlike the Extended Lock-Up and the General Lock-Up described above, the Three Year Lock-Up does not terminate early based on the share price performance of Class A Common Stock.

PIPE Subscription Agreements

In connection with the execution of the Business Combination Agreement, the Company entered into subscription agreements with certain private investors (the “Subscription Agreements”), pursuant to which, among other things, such investors have subscribed to purchase an aggregate of6,680,000shares of Class A Common Stock (together, the “Subscriptions”) for a purchase priceof $10.00per share, or an aggregate purchase price of $66,800,000, which shares are to be issued at the Closing; provided that the Subscription Agreements permit the Company to accept additional subscriptions for a purchase price of$10.00per share to be issued at the Closing, following the execution of the Business Combination Agreement. The obligations of each party to consummate the Subscriptions are conditioned upon, among other things, customary closing conditions and the consummation of the transactions contemplated by the Business Combination Agreement.

Non-Redemption Agreements

In connection with the execution of the Business Combination Agreement, the Sponsor, as the holder of 5,750,000 shares of Class B Common Stock (the Founder Shares (as defined in Note 5)), the Company and each of Morgan Stanley Investment Management Inc., T. Rowe Price Group, Inc., The Invus Group, LLC and ARK Investment Management LLC and/or their respective investment funds (each, an “Investor”, and collectively, the “Investors”) entered into non-redemption agreements in respect of the Public Shares held by the Investors (the “Non-Redemption Agreements”).

Pursuant to the Non-Redemption Agreements, each Investor agreed for the benefit of the Company (a) to not redeem the shares of Class A Common Stock beneficially owned by it, or any other shares, capital stock or other equity interests, as applicable, of the Company, which it held on the date of the Non-Redemption Agreement, representing 8,691,655 shares of Class A Common Stock, in the aggregate (the “Investor Shares”), and (b) to not, among other things, sell, encumber or otherwise transfer the Investor Shares other than in connection with non-discretionary ETF or mutual fund pro rata rebalancing transfers. In connection with these commitments from the Investors, the Sponsor agreed to forfeit 965,728 shares of its Class B Common Stock and the Company has agreed to cancel such shares and concurrently issue to the Investors an equivalent number of shares of Class A Common Stock, in each case, at or promptly following the consummation of the Merger.

Investor Rights Agreement

In connection with the Closing, the Company, certain stockholders of the Company (including the Sponsor) and certain stockholders of Senti will enter into an investor rights and lock-up agreement (the “Investor Rights Agreement”). Pursuant to the Investor Rights Agreement, each signatory thereto (other than the Company) will be granted certain registration rights with respect to their respective shares of Class A Common Stock.

DYNAMICS SPECIAL PURPOSE CORP.

DECEMBER 31, 2021

The Investor Rights Agreement will also restrict the ability of each stockholder who is a party thereto (other than the Company) to transfer its shares of Class A Common Stock (or any securities convertible into or exercisable or exchangeable for shares of Class A Common Stock) for, subject to certain permitted transfers and depending on the stockholder, a period of one year following the Closing Date (the “12 Month Lock-Up”) or a period of 18 months following the Closing Date (the “18 Month Lock-Up”); provided that (i) the foregoing restrictions shall not apply to any shares of Class A Common Stock purchased pursuant to the Subscription Agreements and (ii)(A) in respect of the 12 Month Lock-Up, if the last reported sale price of the Class A Common Stock on Nasdaq, or any other national securities exchange on which the Class A Common Stock is then traded, is greater than or equal to $12.00 per share over any 20 trading days within any consecutive 30 trading day period commencing at least 150 days after the Closing Date, then the 12 Month Lock-Up shall be deemed to have expired with respect to each stockholder’s Class A Common Stock subject to that lock-up; and (B) in respect of the 18 Month Lock-Up, if the last reported sale price of the Class A Common Stock on Nasdaq, or any other national securities exchange on which the Class A Common Stock is then traded, is greater than or equal to $12.00 per share over any 20 trading days within any consecutive 30 trading day period commencing at least 330 days after the Closing Date, then the 18 Month Lock-Up shall be deemed to have expired with respect to each stockholder’s Class A Common Stock subject to that lock-up.

Going Concern

As of December 31, 2021, the Company had $889,323 in cash held outside of the Trust Account and a working capital deficit of $1,984,816. The Company has incurred and expects to continue to incur significant costs in pursuit of its acquisition plans (including in respect of the Senti Business Combination). These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of time within one year after the date that the consolidated financial statements are issued. Management plans to address this uncertainty through the Senti Business Combination, as discussed above. There is no assurance that the Company’s plans to consummate the Senti Business Combination (or any other Business Combination) will be successful or successful within the Combination Period. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations, and/or search for a target company, the specific impact is not readily determinable as of the date of these consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2021. As of December 31, 2021, we had operating cash (i.e. cash held outside the Trust Account) of $889,323.

Investments Held in Trust Account

As of December 31, 2021, the assets held in the Trust Account were comprised of U.S. government securities, within the meaning set forth in Section 2(a) (16) of the Investment Company Act, with maturities of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account

F-15

DYNAMICS SPECIAL PURPOSE CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2021

are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the consolidated balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities are reported in the statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Class A Common Stock Subject to Possible Redemption

The Public Shares sold in the Initial Public Offering contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, if there is a stockholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s Amended and Restated Certificate of Incorporation. In accordance with SEC and its staff’s guidance on redeemable equity instruments, which has been codified in Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity, redemption provisions not solely within the control of the Company require common stock subject to redemption to be classified outside of permanent equity. Therefore, all Class A Common Stock has been classified outside of permanent equity.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable common stock to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable common stock are affected by charges against additional paid in capital and accumulated deficit.

As of December 31, 2021, the Investor Shares (see Note 1) are classified as temporary equity within Class A Common Stock subject to redemption in the Company’s consolidated balance sheet. The Non-Redemption Agreements are terminated in the event that the Business Combination Agreement as described above is terminated. As such, the Company determined that the Non-Redemption Agreements are contingent upon the successful completion of the Senti Business Combination. In the event that the Senti Business Combination is not successful, the Non-Redemption Agreements are terminated, and the Investors would again have the right to redeem the Investor Shares. As such, the Company determined that the Non-Redemption Agreements would not change the nature of the underlying shares as redeemable.

As of December 31, 2021, the Class A Common Stock subject to redemption reflected in the consolidated balance sheet is reconciled in the following table:


Gross proceeds	$	230,000,000
Less:
Issuance costs allocated to Class A Common Stock		(13,181,867	)
Plus:
Remeasurement of carrying value to redemption value		13,181,867

Class A Common Stock subject to possible redemption	$	230,000,000

Offering Costs Associated with the Initial Public Offering

The Company complies with the requirements of ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A—Expenses of Offering. Offering costs consist principally of professional and registration fees incurred

F-16

DYNAMICS SPECIAL PURPOSE CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2021

related to the Initial Public Offering. Offering costs directly attributable to the issuance of an equity contract to be classified in equity are recorded as a reduction in equity. Offering costs for equity contracts that are classified as assets and liabilities are expensed immediately. The Company incurred offering costs amounting to $13,198,430 as a result of the Initial Public Offering (consisting of a $4,600,000 underwriting fee, $8,050,000 of deferred underwriting fees, and $548,430 of other offering costs). The Company recorded $13,181,867 of offering costs as a reduction of temporary equity in connection with the issuance of the Public Shares. The Company recorded $16,563 of offering costs as a reduction of permanent equity in connection with the issuance of the Private Placement Shares.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under ASC Topic 740, Income Taxes (“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Net Loss Per Share of Common Stock

Net loss per common share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. As the Public Shares are considered to be redeemable at fair value, and a redemption at fair value does not amount to a distribution different than other stockholders, Class A Common Stock and Class B Common Stock are presented as one class of stock in calculating net loss per share. As a result, the calculated net loss per share is the same for Class A Common Stock and Class B Common Stock. As of December 31, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the periods presented.

The following table reflects the calculation of basic and diluted net loss per common share (in dollars, except per share amounts):

Basic and diluted net loss per share	$	(0.17	)	$	(0.17	)

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Fair Value of Financial Instruments

The Company applies ASC Topic 820, Fair Value Measurement (“ASC 820”), which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances.

The carrying amounts reflected in the consolidated balance sheet for current assets and current liabilities approximate fair value due to their short-term nature.

Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.

Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities.

See Note 9 for additional information on assets and liabilities measured at fair value.

Recent Accounting Standards

In August 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”) to simplify accounting for certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective January 1, 2022 and should be applied on a full or modified retrospective basis, with early adoption permitted beginning on January 1, 2021. The Company adopted ASU 2020-06 effective January 1, 2021 using the modified retrospective method of transition. The adoption of ASU 2020-06 did not have a material impact on the consolidated financial statements for the fiscal year ended December 31, 2021.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.

NOTE 3. INITIAL PUBLIC OFFERING

The registration statement for the Company’s Initial Public Offering was declared effective on May 25, 2021. On May 28, 2021, the Company completed its Initial Public Offering of 23,000,000 shares of Class A Common Stock, including 3,000,000 shares of Class A Common Stock that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at $10.00 per Public Share, generating gross proceeds of $230,000,000.

NOTE 4. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 715,500 Private Placement Shares at a price of $10.00 per Private Placement Share, generating gross proceeds of $7,155,000. A portion of the proceeds from the sale of the Private Placement Shares was added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Shares held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

NOTE 5. RELATED PARTY TRANSACTIONS

Founder Shares

On March 8, 2021, the Sponsor was issued 5,750,000 shares (the “Founder Shares”) of Class B Common Stock for an aggregate price of $25,000. The Founder Shares included an aggregate of up to 750,000 shares of Class B Common Stock subject to forfeiture by the Sponsor to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the Sponsor would own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering (excluding the Private Placement Shares) (assuming the Sponsor did not purchase any Public Shares in the Initial Public Offering, which it did not). The underwriter fully exercised the over-allotment option on May 28, 2021; thus, these 750,000 Founder Shares are no longer subject to forfeiture.

DYNAMICS SPECIAL PURPOSE CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2021

In connection with the Non-Redemption Agreements (see Note 1), the Sponsor has agreed to forfeit 965,728 Founder Shares and the Company has agreed to cancel such Founder Shares and concurrently issue to the Investors an equivalent number of shares of Class A Common Stock, in each case, at or promptly following the consummation of the Merger. The Company evaluated the forfeiture and cancellation of the Founder Shares by the Sponsor and concurrent issuance of an equivalent number of shares of Class A Common Stock to the Investors in accordance with Staff Accounting Bulletin Topic5A. The forfeiture and cancellation of the Founder Shares by the Sponsor and concurrent issuance of an equivalent number of shares of Class A Common Stock to the Investors has not been transacted as of December 31, 2021 and will not occur until at or promptly following the consummation of the Merger. As such, any expense associated with the issuance of the shares of Class A Common Stock to the Investors would be recognized at the date of issuance (i.e., upon consummation of the Merger).

Promissory Note—Related Party

On March 8, 2021, the Company issued an unsecured promissory note to the Sponsor (the “Promissory Note”), pursuant to which the Company could borrow an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering. The Promissory Note was non-interest bearing and was payable on the earlier of December 31, 2021 or the consummation of the Initial Public Offering. In April 2021, the Company borrowed $250,000 under the Promissory Note which was repaid in full on May 26, 2021.

Related Party Loans

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds held in the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination is not completed, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. Up to $2,000,000 of such Working Capital Loans may be convertible into shares at a price of $10.00 per share at the option of the lender. The shares would be identical to the Private Placement Shares.

Administrative Support Agreement

The Company entered into an agreement, commencing on the effective date of the Initial Public Offering, to pay the Sponsor up to a total of $10,000 per month for office space, administrative and support services. Upon the completion of an initial Business Combination, the Company will cease paying these monthly fees (if any). To date, the Company has not exercised its option to use such services.

NOTE 6. COMMITMENTS AND CONTINGENCIES

Registration Rights

The holders of the Founder Shares, Private Placement Shares and any Class A Common Stock issuable upon conversion of any Working Capital Loans have registration rights pursuant to a registration and stockholder rights agreement signed in connection with our Initial Public Offering. The holders of these securities are entitled

DECEMBER 31, 2021

to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of an initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

In addition, it is anticipated that each signatory to the Investor Rights Agreement (see Note 1), other than the Company, will be granted certain registration rights with respect to their respective shares of Class A Common Stock when that agreement is signed (which is expected to occur at Closing).

Underwriting Agreement

The Company granted the underwriter of its Initial Public Offering a 45-day option to purchase up to 3,000,000 additional shares of Class A Common Stock to cover over-allotments at the Initial Public Offering price, less the underwriting discounts and commissions. The underwriter exercised the over-allotment option in full on May 28, 2021.

The underwriter was paid a cash underwriting fee of $0.20 per share, or $4,600,000 in the aggregate, upon the closing of the Initial Public Offering. In addition, $0.35 per share, or $8,050,000 in the aggregate was payable to the underwriter for deferred underwriting commissions. On December 17, 2021, the underwriter agreed to waive its right to $1,000,000 of the fee payable by the Company for deferred underwriting commissions. The waived fee was recorded to accumulated deficit. The revised deferred underwriting fee of $7,050,000 will become payable to the underwriter from the amount held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Financial Advisor Agreement

On December 16, 2021, the Company entered into an agreement (the “Financial Advisor Agreement”) with Morgan Stanley & Co. LLC (“Morgan Stanley”) for financial advisory services in connection with the Senti Business Combination, which services Morgan Stanley had been engaged to provide, and which services Morgan Stanley had provided, since August 4, 2021. The Financial Advisor Agreement shall terminate automatically on December 16, 2022 unless terminated earlier, with or without cause, by either the Company or Morgan Stanley. The Company will pay Morgan Stanley a fee of $1,000,000 upon the consummation of our proposed initial business combination with Senti.

Placement Agent Agreement

On September 21, 2021, the Company entered into an agreement (the “Placement Agent Agreement”) with Morgan Stanley, J.P. Morgan Securities LLC and BofA Securities, Inc. (together, the “Placement Agents”) for services in connection with the placement of shares of our Class A Common Stock to certain private investors which is anticipated to occur concurrently with the completion the Senti Business Combination (i.e. the Subscriptions – see Note 1). The Placement Agent Agreement shall terminate automatically on August 28, 2022 unless terminated earlier, with or without cause, by either the Company or any Placement Agent (as to itself only). The Company will pay to the Placement Agents a total fee equal to 4.0% of the aggregate price at which the shares of our Class A Common Stock are sold to the private investors in the Subscriptions, which fee shall be payable upon the consummation of the placement of the shares. Each of the Placement Agents will receive 33.3% of the fee.

NOTE 7. STOCKHOLDERS’ DEFICIT

Preferred stock — The Company is authorized to issue 1,000,000 shares of preferred stock with a par value of $0.0001 per share with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of December 31, 2021, there were no shares of preferred stock issued or outstanding.

Class A Common Stock — The Company is authorized to issue 100,000,000 shares of Class A Common Stockwith a par value of $0.0001 per share. Holders of Class A Common Stockare entitled to one vote for each share. As of December 31, 2021, there were 23,715,500 shares of Class A Common Stock issued and outstanding, including 23,000,000 shares of Class A common stock subject to possible redemption. Despite the Non-Redemption Agreements discussed in Note 1, it is possible, in certain limited circumstances, for the Investors to transfer their Public Shares, and a transfer of such shares to a third party who is not bound by a Non-Redemption Agreement would render such shares subject to possible redemption.

Class B Common Stock — The Company is authorized to issue 10,000,000 shares of Class B Common Stock with a par value of $0.0001 per share. Holders of Class B Common Stock are entitled to one vote for each share. As of December 31, 2021, there were 5,750,000 shares of Class BCommon Stock issued and outstanding. Of the 5,750,000 shares of Class B Common Stock initially issued and outstanding, up to 750,000 shares were subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriter’s over-allotment option was not exercised in full or in part, so that the initial stockholders would collectively own 20% of the Company’s issued and outstanding common stock after the Initial Public Offering (excluding the Private Placement Shares). The over-allotment option was exercised in full on May 28, 2021; thus, these shares are no longer subject to forfeiture.

Common stockholders of record are entitled to one vote for each share held on all matters to be voted on by stockholders. Holders of the Class A Common Stock and holders of the Class B Common Stock will vote together as a single class on all matters submitted to a vote of stockholders, including any vote in connection with an initial Business Combination, except where a vote of each class is required by law.

The shares of Class B Common Stock are convertible into shares of Class A Common Stock at the option of the holder and will automatically convert into shares of Class A Common Stock at the time of an initial Business Combination on a one-for-one basis (subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like). In the case that additional shares of Class A Common Stock, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in the Initial Public Offering and related to the closing of an initial Business Combination, the ratio at which shares of Class B Common Stock shall convert into shares of Class A Common Stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B Common Stock agree to waive such adjustment with respect to any such issuance or deemed issuance, as is the case for the proposed Senti Business Combination) so that the number of shares of Class A Common Stock issuable upon conversion of all shares of Class B Common Stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of all shares of common stock

outstanding upon the completion of the Initial Public Offering (excluding the Private Placement Shares), plus (ii) all shares of Class A Common Stock and equity-linked securities issued or deemed issued in connection with an initial Business Combination (excluding any shares of Class A Common Stock or equity-linked securities issued, or to be issued, to any seller in an initial Business Combination and any Private Placement Shares issued to the Sponsor or its affiliates upon conversion of any Working Capital Loans).

NOTE 8. INCOME TAX

The Company’s net deferred tax assets (liabilities) as of December 31, 2021 is as follows:


Deferred tax assets:
Start-upcosts	$	551,466
Net operating loss carryforwards		32,562

Total deferred tax assets		584,028
Valuation allowance		(584,028	)

Deferred tax assets, net of allowance	$	0

The income tax provision for the period from March 1, 2021 (inception) through December 31, 2021 consists of the following:


Federal
Current	$	0
Deferred		(584,028	)
State
Current		0
Deferred		0
Change in valuation allowance		584,028

Income tax provision	$	0

As of December 31, 2021, the Company has available U.S. federal operating loss carry forwards of approximately $155,000 that may be carried forward indefinitely.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences representing future deductible amounts become deductible. Management considers the scheduled reversal of deferred tax assets, projected future taxable income and tax planning strategies in making this assessment. After consideration of all the information available, management believes that significant uncertainty exists with respect to future realization of the deferred tax assets and has therefore established a full valuation allowance. For the period ended December 31, 2021, the valuation allowance was $584,028.

DECEMBER 31, 2021

A reconciliation of the federal income tax rate to the Company’s effective tax rate as of December 31, 2021 is as follows:


Statutory federal income tax rate	21.0	%
State taxes, net of federal tax benefit	0.0	%
Other	0.0	%
Change in valuation allowance	(15.1	)%
Business Combination transaction costs	(5.9	)%

Income tax provision	0.0	%

The Company’s effective tax rates for the period presented differ from the expected (statutory) rates due to the recording of full valuation allowances on deferred tax assets and permanent differences.

The Company files income tax returns in the U.S. federal jurisdiction and California which remain open and subject to examination.

NOTE 9. FAIR VALUE MEASUREMENTS

The following table presents information about the Company’s financial assets that are measured at fair value on a recurring basis as of December 31, 2021, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

NOTE 10. SUBSEQUENT EVENTS

The Company evaluated subsequent events and transactions that occurred after the consolidated balance sheet date up to the date that the consolidated financial statements were issued. Based upon this review, other than the amendments to the Business Combination Agreement and Senti Support Agreements as discussed in Note 1, the Company did not identify any subsequent events that would have required adjustment or disclosure in the consolidated financial statements.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Senti Biosciences, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Senti Biosciences, Inc. and subsidiary (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations and comprehensive loss, redeemable convertible preferred stock and stockholders’ deficit, and cash flows for the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred recurring losses and negative cash flows from operations, and has an accumulated deficit that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2019.

Notes to Consolidated Financial Statements

1. Organization and Description of Business

Senti Biosciences, Inc. or (the “Company”), was incorporated under the laws of the State of Delaware in June 2016, and is a biotechnology company that programs next-generation cell and gene therapies with what we refer to as “gene circuits.” The Company is headquartered in South San Francisco, California.

Liquidity and Going Concern

The Company has devoted substantially all of its efforts to organizing and staffing, business planning, raising capital, and conducting preclinical studies and has not realized substantial revenues from its planned principal operations. In addition, the Company has a limited operating history, has incurred recurring operating losses and negative cash flows from operations since inception, has an accumulated deficit, has funded its operations primarily with proceeds from sale of redeemable convertible preferred stock and the issuance of convertible notes, and expects that it will continue to incur net losses and negative cash flows from operations into the foreseeable future, particularly as the Company advances its preclinical activities and clinical trials for its product candidates in development.

The Company’s continued existence is dependent upon management’s ability to develop profitable operations. Management is devoting substantially all of its efforts to developing its business and raising capital and there can be no assurance that the Company’s efforts will be successful. No assurance can be given that management’s actions will result in profitable operations or the meeting of ongoing liquidity needs.

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. In 2021 and 2020, the Company received aggregate proceeds of $67.0 million and $30.0 million, respectively, (Note 6) from the issuance of its Series B redeemable convertible preferred stock. Additionally, in 2020, the Company received $8.0 million from the issuance of promissory notes (Note 5). As of December 31, 2021, the Company had an accumulated deficit of $115.1 million, and cash, cash equivalents and restricted cash of $59.3 million. As of December 31, 2020, the Company had an accumulated deficit of $59.8 million, and cash, cash equivalents and restricted cash of $31.0 million.

As of April 1, 2022, the issuance date of the consolidated financial statements as of and for the year ended December 31, 2021, the Company expects that its cash and cash equivalents will not be sufficient to fund its operating expenses and capital expenditure requirements for at least one year from the issuance date of the consolidated financial statements and therefore the Company concluded that substantial doubt existed about the Company’s ability to continue as a going concern.

The Company is seeking to complete a liquidity event via a special purpose acquisition company (“SPAC”) (see pending merger with Dynamics Special Purpose Corp. below). Upon the completion of a qualified public offering on specified terms (Note 6), the Company’s outstanding convertible preferred stock will automatically convert into shares of common stock. These plans are intended to mitigate the relevant conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern; however, as the plans are not entirely within the Company’s control, management cannot assure they will be effectively implemented. In the event the Company does not complete a SPAC merger, the Company expects to seek additional funding through private equity financings, debt financings, collaborations, licensing arrangements, and/or strategic alliances. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other such arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. If the Company is unable to raise capital when needed, or on attractive terms, it could be forced to delay, reduce or eliminate its research or drug development programs or any future commercialization efforts.

F-31

Pending Merger with Dynamics Special Purpose Corp.

On December 19, 2021, the Company entered into a Business Combination Agreement with Dynamics Special Purpose Corp. (“DYNS”), a publicly traded SPAC. Under the terms of the proposed transaction, DYNS will merge with the Company at an estimated combined enterprise value of approximately $276.0 million. The cash components of the transaction will be funded by DYNS’ cash in trust of $230.0 million (assuming no redemptions) as well as a $66.8 million private placement of common stock at $10.00 per share from various accredited investors.

2. Summary of Significant Accounting Policies and Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of Senti Biosciences, Inc., and its wholly-owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation. We have one business activity and operate in one reportable segment.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the accrual for research and development expenses, the valuation of stock-based awards, the valuation of convertible notes, the valuation of common and redeemable convertible preferred stock, the valuation of preferred stock tranche liability, standalone selling price (“SSP”) and the determination of the incremental borrowing rate. Actual results could differ from those estimates, and such differences could be material to the financial position and consolidated statements of operations and comprehensive loss.

Impact of the COVID-19 Coronavirus

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist of cash, cash equivalents, and short-term investments that are maintained in checking and money market accounts at one financial institution, which at times, may exceed federally insured limits. The Company’s short-term investments, if any, are limited to certain types of debt securities issued by the U.S. government, its agencies, and institutions with investment-grade credit ratings, and places restrictions on maturities and concentration by type and issuer. The Company believes that it is not exposed to significant credit risk due to the

F-32

financial position of the institutions in which those deposits and short-term investments are held. As of December 31, 2021 and 2020, the Company has not experienced any credit losses in such accounts or investments.

Cash, Cash Equivalents, and Restricted Cash

Cash equivalents consist of amounts deposited in money market funds and securities with original maturity dates of three months or less, which are stated at fair value.

The Company’s restricted cash consists of cash deposited with a financial institution as collateral for a letter of credit required under the Company’s headquarters and research facility leases. The restricted cash is presented separately from cash and cash equivalents and classified as non-current on the balance sheet, as the Company expects the cash to remain restricted for a period greater than one year.

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that total to the amounts shown in the consolidated statements of cash flows for the Company:


	December 31,
	2021		2020
Cash and cash equivalents		56,034		30,537
Restricted cash		3,257		497

Total	$	59,291	$	31,034

Short-term Investments

Investments in marketable securities with original maturities less than 12 months from the balance sheet date, if any, are classified as short-term investments. Investments with original maturities of greater than 12 months from the balance sheet date, if any, are classified as long-term. The Company classifies all of its investments as available-for-sale and records such assets at estimated fair value in the balance sheet, with unrealized gains and losses, if any, reported as a component of other comprehensive loss within the consolidated statement of operations and comprehensive loss, and as a separate component of stockholders’ equity. These investments consist of corporate debt securities, U.S. Government securities, asset-based securities, and commercial paper, which are subject to minimal credit and market risk. The Company uses the specific identification method to determine the amount of realized gains or losses on sales of marketable securities. Realized gains and losses on sales of securities and declines in the fair value of securities judged to be other than temporary are included in other income or expense. Unrealized gains and losses are included in other comprehensive loss. Interest on available-for-sale securities is included in interest income in the consolidated statements of operations and comprehensive loss.

Fair Value Measurements

Certain assets and liabilities of the Company are carried at fair value under U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:

•

Level 1 – Quoted prices in active markets for identical assets or liabilities.

F-33

•

Level 2 – Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

•

Level 3 – Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies, and similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The estimated fair values of the Company’s cash and cash equivalents, restricted cash, trade, and other receivables and accounts payable approximate their carrying values given their short-term nature.

The Company’s convertible notes and preferred stock tranche liability were carried at fair value from the date of issuance through their respective extinguishment in October 2020 and May 2021, and were determined using Level 3 inputs in the fair value hierarchy described above.

Property and Equipment, Net

Property and equipment, net is stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which are as follows:


Small equipment			2 years
Computer equipment and software			3 years
Laboratory equipment			5-7 years
Furniture and fixtures			5-7 years
Leasehold improvements			Shorter of the lease term and the useful life

The Company capitalizes certain costs incurred during the construction phase of a project or asset into construction-in-progress. Once the construction is complete and the asset is placed into service, we transfer its carrying value into the appropriate fixed asset category and begin depreciating the value over its useful life.

When assets are retired or disposed of, any resulting gain or loss is included in net loss. Expenditures for maintenance and repairs are expensed as incurred.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets, such as property and equipment, net, for impairment whenever events or changes in circumstances indicate that the carrying value of assets may not be recoverable. Recoverability of these assets is measured by comparing their carrying value to the future net undiscounted cash flows the assets are expected to generate over their remaining economic life. If such assets are considered to be impaired, the amount of any impairment is measured as the difference between their carrying value and their fair value. If the useful life is shorter than originally estimated, the Company amortizes the remaining carrying value over the revised shorter useful life.

Leases

The Company determines if an arrangement is or contains a lease at inception. Operating leases are recorded on the consolidated balance sheets with right-of-use assets (“ROU”) representing the Company’s right to use an

F-34

underlying asset for the lease term and lease liabilities representing the Company’s obligation to make lease payments. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Operating lease ROU assets also include the effect of any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company’s leases is typically unknown, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. The Company gives consideration to its credit risk, the term of the lease, and total lease payments and adjusts for the impacts of collateral as necessary when calculating its incremental borrowing rates. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term. Variable lease payments are recorded as an expense in the period incurred.

The Company has elected to not separate lease and non-lease components for any leases within its existing classes of assets and, as a result, accounts for any lease and non-lease components as a single lease component. The Company has also elected not to apply the recognition requirement for leases with a term of 12 months or less.

Revenue Recognition

Contract Revenue

Revenue is recognized when a customer obtains control of promised goods or services. The Company applies the following five steps to recognize revenue: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations in the contract; and (v) recognize revenue when (or as) the performance obligations are satisfied.

A performance obligation is defined as a promise to transfer a product or a service to a customer that is distinct. A product or a service is distinct if both (i) the customer can benefit from the product or the service either on its own or together with other resources that are readily available to the customer and (ii) the Company’s promise to transfer the product or the service to the customer is separately identifiable from other promises in the contract. Each distinct promise to transfer a product or a service is a unit of accounting for revenue recognition. If a promise to transfer a product or a service is not distinct from other promises in the contract, such promises should be combined into a single performance obligation. The assessment of each of these elements may require significant judgments.

The transaction price is the amount of consideration the Company is entitled to receive in exchange for the transfer of control of a product or a service to a customer. The Company’s agreements may include both fixed and variable consideration. Fixed payments are included in the transaction price, while variable consideration, such as milestone payments and fees for research services, are estimated and constrained (if required) at the inception of the contract and evaluated on a periodic basis thereafter.

If a contract has multiple performance obligations, the Company allocates the transaction price to each distinct performance obligation based on the relative stand-alone selling price (“SSP”) of the performance obligation. The Company determines SSP at contract inception and at contract modification. Determining the

F-35

SSP for performance obligations requires significant judgment. Changes in the key assumptions used to determine the SSP could have a significant effect on the allocation of arrangement consideration between multiple performance obligations.

For each distinct performance obligation, revenue is recognized as the Company transfers control of the product or the service applicable to such performance obligations. In instances where the Company first receives consideration in advance of satisfying its performance obligation, the Company classifies such consideration as deferred revenue until the Company satisfies such performance obligations. In instances where the Company first satisfies its performance obligation prior to its receipt of consideration, the consideration is a contract asset recorded in prepaid expenses and other current assets on the consolidated balance sheets.

Grant Income

The Company receives government grants that reimburse the Company for certain allowable costs for funded projects. Grant income is recognized on a systematic basis over the period in which the Company recognizes qualified research and development costs that grant is intended to compensate and there is reasonable assurance that the Company will meet the terms and conditions of the grant. This income is recorded as grant income in the consolidated statements of operations and comprehensive loss.

Grant payments received in excess of grant revenue earned are recognized as deferred revenue on the balance sheets, and grant income earned in excess of grant payments received is recognized as trade and other receivables on the consolidated balance sheets.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development costs consist of salaries and other personnel-related expenses, including associated stock-based compensation, lab supplies and services, in-license and technology costs, consulting and sponsored research fees, facility costs and depreciation expense.

Nonrefundable advance payments for goods and services that will be used or received in future research and development activities are deferred and recognized as an expense in the period in which the related goods are delivered, or services are performed.

The Company has acquired and may continue to acquire the rights to gene circuit or other technologies from third parties. The upfront payments to acquire a license, product, or rights, as well as any annual maintenance charges and future milestone payments, are immediately recognized as research and development expense provided that there is no alternative future use of the rights in other research and development projects.

Deferred Offering Costs

Deferred offering costs consists of incremental legal, accounting and other fees directly attributable to equity offerings. Deferred offering costs are capitalized within prepaid and other current assets on the consolidated balance sheets and are offset against proceeds of the offering in the consolidated statements of redeemable convertible preferred stock and stockholders’ deficit as a reduction of additional paid-in capital upon the completion of the equity offering. In the event the equity offering is terminated, all of the deferred offering costs are expensed within the Company’s consolidated statements of operations and comprehensive loss. For the year ended December 31, 2021 the Company expensed $2.2 million of previously deferred offering costs related to the suspended IPO within general and administrative expense on the consolidated statement of operations and comprehensive loss. As of December 31, 2021, the Company has recorded $1.4 million of deferred offering costs related to the pending SPAC merger that is included in prepaids and other current assets. There were no deferred offering costs as of December 31, 2020.

F-36

Commitments and Contingencies

The Company recognizes a liability with regard to loss contingencies when it believes it is probable a liability has occurred and the amount can be reasonably estimated. If some amount within a range of loss appears at the time to be a better estimate than any other amount within the range, the Company accrues that amount. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company has not recorded any such liabilities as of December 31, 2021 and 2020.

Fair Value Option for Convertible Notes

The Company elected to account for its convertible notes at fair value as of the issuance date in order to measure those liabilities at amounts that more accurately reflect the current economic environment in which the Company operates. Accordingly, the Company recorded these convertible notes issued in August 2020 at fair value with changes in fair value recognized in change in fair value of convertible notes in the consolidated statements of operations and comprehensive loss. As a result of applying the fair value option, direct costs and fees related to the convertible notes were expensed in the period incurred.

Accretion and Classification of Redeemable Convertible Preferred Stock

The Company’s redeemable convertible preferred stock is recorded based on proceeds received, net of the related preferred stock tranche liability and issuance costs, and is classified outside of stockholders’ deficit on the consolidated balance sheets because the holders of such shares have liquidation rights in the event of a deemed liquidation that, in certain situations, are not solely within the control of the Company and would require the redemption of the then-outstanding redeemable convertible preferred stock. The Company’s Series A and Series B redeemable convertible preferred stock are subject to liquidation, dissolution, or winding up of the Company, either voluntary or involuntary (Note 6). Because the occurrence of a deemed liquidation event is not currently probable as of December 31, 2021, the carrying values of the redeemable convertible preferred stock are not being accreted to their redemption values. Subsequent adjustments to accrete the carrying values of the redeemable convertible preferred stock to its redemption price would be made only when a deemed liquidation event becomes probable.

Preferred Stock Tranche Liability

The Company’s Series B redeemable convertible preferred stock included an obligation whereby the investors agreed to buy, and the Company agreed to sell additional shares at a fixed price in the event that certain agreed-upon milestones were achieved or at the election of investors. This obligation was determined to be a freestanding financial instrument that should be accounted for as a liability at fair value (Notes 3 and 6). This preferred stock tranche liability was revalued at each reporting period through settlement with changes in the fair value recorded as a change in preferred stock tranche liability in the consolidated statements of operations and comprehensive loss. The fair value at settlement was reclassified to redeemable convertible preferred stock at such time.

Stock-Based Compensation

The Company recognizes stock-based compensation expense related to employees and non-employees based on the grant date fair value of the awards. For awards that vest solely based on continued service, stock-based compensation expense is recognized in the consolidated statements of operations using the straight-line method. For performance and market awards, stock-based compensation expense is recognized over the requisite service period using the accelerated attribution method. No compensation expense will be recognized for awards subject to performance conditions until it is probable that the performance condition will be met.

The Company has allowed specified option holders to exercise unvested options. The options that are exercised prior to vesting continue to vest according to the respective option agreement, and such unvested shares are subject to repurchase by the Company at the option holder’s original exercise price in the event the option holder’s service with the Company voluntarily or involuntarily terminates.

F-37

The Company records proceeds from the early exercise of options as a current and long-term liability in the consolidated balance sheet, and reclassifies this liability to additional paid-in capital as the Company’s repurchase right lapses. The shares purchased by the option holders pursuant to the early exercise of stock options are not deemed, for accounting purposes, to be outstanding until those shares have vested.

Net Loss Per Share

The Company follows the two-class method when computing net loss per share as the Company has issued shares that meet the definition of participating securities. The two-class method determines net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires loss available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to share in undistributed earnings as if all loss for the period had been distributed.

Basic net loss per share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted net loss per share attributable to common stockholders is computed by adjusting net loss attributable to common stockholders for an allocation of the undistributed earnings and dividing it by the weighted-average number of common shares outstanding for the period, including potential dilutive common shares. For purposes of this calculation, the Company’s outstanding stock options, redeemable convertible preferred stock, and potential issuance of redeemable convertible preferred stock under existing preferred stock tranches, are considered potential dilutive common shares.

The Company’s participating securities contractually entitle the holders of such securities to participate in dividends but do not contractually require the holders of such securities to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the consolidated statement of operations in the period that includes the enactment date.

The Company recognizes net deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If management determines that the Company would be able to realize its deferred tax assets in the future in excess of their net recorded amount, management would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions on the basis of a two-step process whereby (i) management determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold,

F-38

management recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within income tax expense. Any accrued interest and penalties are included within the related tax liability. To date, there have been no interest charges or penalties related to unrecognized tax benefits.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. For trade receivables and other instruments, a new forward-looking expected loss model that generally results in the earlier recognition of allowances for losses will be required. The Company adopted this standard as of January 1, 2021, which did not have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), which eliminates, modifies, and adds disclosure requirements for fair value measurements. The Company adopted this standard as of January 1, 2021, and modified its disclosures accordingly. The standard did not have a material impact on the Company’s consolidated financial statements.

In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. The Company adopted this standard as of January 1, 2021 which did not have a material impact on its consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which removes certain exceptions to the general principles in Topic 740 and improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This ASU is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years with early adoption permitted. The Company is currently evaluating the impact of this standard but does not expect the adoption will have a material impact on its consolidated financial statements and related disclosures.

In March 2020, the Financial Accounting Standards Board issued ASU No. 2020-03, Codification Improvements to Financial Instruments. This standard improves and clarifies various financial instruments topics and includes seven different issues that describe the areas of improvement and the related amendments to GAAP that are intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications. This ASU is effective January 1, 2023 with early adoption permitted. The Company is currently evaluating the impact of this standard.

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. This standard is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

F-39

In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements, which moves all disclosure guidance to the appropriate codification section and makes other improvements and technical corrections. The standard is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) - Disclosures by Business Entities about Government Assistance, which seeks to increase the transparency of government assistance including the disclosure of (1) the types of assistance, (2) an entity’ accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements. Diversity currently exists in the recognition, measurement, presentation, and disclosure of government assistance received by business entities because of the lack of specific authoritative guidance in U.S. GAAP. ASU 2021-10 is effective for fiscal years beginning after December 15, 2021. Early application of the amendments is permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In May 2021, the FASB issued ASU 2021-04 Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 370-50), Compensation-Stock Compensation (Topic 718),and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40); Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force), which clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. The standard is effective for all entities for fiscal years beginning after December 15, 2021. Adoption of this standard will not have a material impact on the Company’s consolidated financial statements.

Convertible Notes

Due to certain embedded features within the convertible notes (Note 5), the Company elected to account for the convertible notes under the fair value option.

At issuance in August 2020, the convertible notes were recorded at fair value of $8.9 million, resulting in a loss on issuance of $0.9 million which is included in the change in fair value of convertible note.

The fair value of the convertible notes at issuance was determined using a probability-weighted income approach as the convertible notes contained various settlement outcomes. The following reflects the significant quantitative inputs used to fair value the convertible notes at issuance.


	On Issuance
Interest rate		8.00	%
Discount rate		6.78	%
Time to maturity (years)		0.49
Probability of automatic conversion upon qualified financing		95.0	%
Probability of optional conversion		2.5	%
Probability of no conversion		2.5	%
Conversion Price	$	1.4784

In connection with the issuance and sale of Series B redeemable convertible preferred stock in October 2020 (Note 6), all of the outstanding principal and accrued interest of $8.1 million under the convertible notes was

F-41

converted into 5,485,858 shares of Series B redeemable convertible preferred stock and the related preferred stock tranche liability. The fair value of the convertibles notes of $8.7 million on the date of conversion was determined using the Backsolve method based on the price of the Series B redeemable convertible preferred stock and, if purchased, the related preferred stock tranche liability.

The following table provides a roll-forward of the fair value of the convertible notes (in thousands):

Preferred Stock Tranche Liability

The initial and subsequent fair values of the preferred stock tranche liability recognized in connection with the issuance of Series B redeemable convertible preferred stock financing were determined with the assistance of a third-party valuation specialist using significant inputs not observable in the market which constitute Level 3 measurements within the fair value hierarchy.

The following reflects the significant quantitative inputs used in the valuation of the preferred stock tranche liability for fiscal year 2020 on initial closing on October 22, 2020, second closing on December 28, 2020 and subsequent measurement as of December 31, 2020 using a Monte Carlo valuation model and/or Black-Scholes option pricing model:


	October 22, 2020 Initial Measurement Date		December 28 and December 31, 2020 Subsequent Measurement Dates
	Tranche 2 Call Option	Tranche 3 Call Option	Tranche Features 2 and 3 Call Option	Tranche 2 and 3 Forward Contracts
Estimated fair value of Series B redeemable convertible preferred stock⁽¹⁾	$1.25	$1.25	$1.62	$1.62

Value of each tranche feature	$0.143	$0.199	$0.326	$(0.023)

(1)	Fair value of the Series B redeemable convertible preferred stock was estimated using the Backsolve method.

The weighted-average fair value of the tranche features on a per share basis was $0.172 as of October 22, 2020, $0.012 as of December 28, 2020 and December 31, 2020.

For the October 2020 issuance of Series B redeemable convertible preferred stock, certain investors received the right to participate in two additional closings at a fixed price which were valued as a call option (Note 6) when issued.

F-42

In connection with the December 2020 issuance of Series B redeemable convertible preferred stock, certain investors of Series B redeemable convertible preferred stock that held 48.65% of the Company’s outstanding shares and have 2 seats on the Company’s board of directors, forfeited their rights to participate in two additional closings of Series B redeemable convertible preferred stock which resulted in the measurement of the preferred stock tranche liability as a combination of a call option and forward contract.

In January 2021, the Company issued additional Series B redeemable convertible preferred stock, and recorded an addition to the tranche liability of $33 thousand in recognition of the obligation to sell additional shares at a fixed price in the event that certain agreed-upon milestones are achieved or at the election of investors.

In April 2021, the Company’s Board of Directors determined that certain technical milestones within the Series B agreements had been achieved and approved the notice to call tranches 2 and 3, subject to requisite stockholders’ written election and related waivers. The second and third closings occurred on May 14, 2021 and all 39,366,050 shares of Series B redeemable convertible preferred stock were acquired thereby extinguishing the preferred stock tranche liability.

The value of the tranche rights acquired on May 14, 2021 was determined using the current value method as both tranches were called by the Company on the valuation date. The following reflects the significant quantitative inputs used in the valuation of the preferred stock tranche liability as of May 14, 2021 using a weighted comparable guideline IPO (high and low) and SPAC transactions for the public scenario and the Black-Scholes pricing model for the staying private scenario:


	May 14, 2021
	Tranches 2 and 3

	Public Scenario	Staying Private Scenario
	Call	Call
Estimated fair value of Series B redeemable convertible preferred stock	$2.18	$1.58
Scenario weighting	75.0%	25.0%
Value of each tranche feature	$1.637	$0.395

Weighted-average value of Series B redeemable convertible preferred stock	$2.032

The difference between the weighted-average value of Series B redeemable convertible preferred stock of $2.032 and the strike price of $1.6427 is the $0.3893 weighted-average fair value of the tranche feature on a per share basis as of May 14, 2021 for a total fair value of $15.2 million.

5. Convertible Notes

In August 2020, the Company issued $8.0 million in convertible notes to existing investors, including related parties, with a stated annual interest rate of 8%. The principal and accrued interest was payable upon maturity in February 2021.

The outstanding balance of principal plus accrued and unpaid interest were automatically convertible at the sale of preferred stock of at least $25.0 million (the “Qualified Financing”). On conversion of the convertible notes in a Qualified Financing, the same class of preferred shares would be issued at a price equal to 90% of the fixed price per share paid by the purchasers of preferred stock participating in the Qualified Financing. In connection with the issuance and sale of Series B redeemable convertible preferred stock in October 2020 (Note 6), all of the outstanding principal and accrued interest of $8.1 million under the convertible notes was converted into 5,485,858 shares of Series B redeemable convertible preferred stock and the related preferred stock tranche liability.

For the year ended December 31, 2020, we recorded a fair value loss of $0.7 million that is included in the change in fair value of convertible notes, in the accompanying consolidated statements of operations and comprehensive loss.

The terms of

F-45

the Series B redeemable convertible preferred stock included the obligations for the investors to purchase, and the Company to sell, 16,842,176 and 18,668,438 additional shares of Series B redeemable convertible preferred stock in two additional closings (“Tranche 2” and “Tranche 3”) for a price of $1.6427 per share.

On December 28, 2020, the Company issued 2,637,929 shares of Series B redeemable convertible preferred stock to new and existing investors for gross proceeds of $4.3 million, net of issuance costs of $0.2 million. These Series B redeemable convertible preferred stock also included obligations for the investors to purchase, and the Company to sell, 2,637,929 additional shares of Series B redeemable convertible preferred stock in both Tranche 2 and Tranche 3 for a price of $1.6427 per share. Also on December 28, 2020, certain investors forfeited their rights and obligations to purchase 1,217,506 and 3,043,768 shares of Series B redeemable convertible preferred stock in Tranche 2 and Tranche 3, respectively.

On January 19, 2021, the Company issued 1,420,426 shares of Series B redeemable convertible preferred stock to investors for gross proceeds of $2.3 million, net of issuance costs of $6 thousand. The terms of the Series B redeemable convertible preferred stock sold are the same as the terms of previous issuances of Series B redeemable convertible preferred stock issued in October 2020, and also included obligations for the investors to purchase, and the Company to sell, 1,420,426 additional shares of Series B redeemable convertible preferred stock in each of Tranches 2 and 3 for a price of $1.6427 per share.

In April 2021, the Company’s Board of Directors determined that the Series B milestone had been achieved and approved the notice to call tranches 2 and 3, subject to requisite stockholders’ written election and related waivers. The second and third closings occurred on May 14, 2021 and the Company issued 39,366,050 shares of Series B redeemable convertible preferred stock to investors for proceeds of $64.7 million for which no additional issuance costs were incurred.

The following is a summary of the rights and privileges of the holders of redeemable convertible preferred stock:

Voting Rights

Each share of redeemable convertible preferred stock has voting rights equal to the number of shares of common stock into which such preferred stock is convertible. The holders of redeemable convertible preferred stock vote together with the holders of common stock as a single class for most matters.

The holders of Series A redeemable convertible preferred stock voting as a separate class are entitled to elect two directors. The holders of Series B redeemable convertible preferred stock voting as a separate class are entitled to elect two directors. The holders of common stock, voting as a separate class, are entitled to elect two directors of the Company. The holders of common stock and redeemable convertible preferred stock, voting as a single class, are entitled to elect the balance of the seven total directors of the Company.

Dividends

The holders of redeemable convertible preferred stock are entitled to receive, if and when declared by the Company’s board of directors, non-cumulative cash dividends at a rate of 8.0% per annum of the original issue price. These holders are also entitled to participate in dividends on common stock on an as-converted basis. No dividends have been declared or paid to date.

Conversion

At the option of the holder, each share of redeemable convertible preferred stock is convertible into shares of common stock as determined by dividing the applicable original issue price by the applicable conversion price in effect at the time of conversion. The initial conversion price of both Series A and Series B redeemable convertible preferred stock is equal to the original issue price of $1.6427 per share. The

F-46

conversion ratio for the redeemable convertible preferred stock shall be subject to appropriate adjustments for stock splits, stock dividends, combinations, recapitalizations, or the like. The conversion ratio at December 31, 2021 and December 31, 2020, respectively, is one-to-one; however, the conversion price is subject to anti-dilution provisions upon issuance of additional shares of common stock or other convertible securities. The holders of the Series A redeemable convertible preferred stock agreed to forfeit the anti-dilution provisions upon the issuance of Series B redeemable convertible preferred stock.

Each share of redeemable convertible preferred stock automatically converts into the number of shares of common stock into which such shares are convertible at the applicable conversion ratio upon the earlier: (i) the closing of the sale of shares of common stock in a qualified initial public offering (“IPO”) resulting in gross proceeds of at least $50.0 million or (ii) the vote or written consent of the holders of the majority of the then-outstanding shares of redeemable convertible preferred stock, voting together as a single class.

If a holder of Series B redeemable convertible preferred stock fails to purchase all of its applicable tranche shares at or prior to the milestone closing, all of the holder’s shares of Series B redeemable convertible preferred stock will automatically convert into the number of shares of common stock into which such shares are convertible at the applicable conversion ratio. Such defaulting holder also forfeits its right to designate a member of or observer to the board of directors and any right to participate in any subsequent debt or equity financing of the Company.

Liquidation

In the event of any liquidation, dissolution, or winding up of the Company, either voluntary or involuntary, the holders of the Series B redeemable convertible preferred stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the holders of the Series A redeemable convertible preferred stock and common stock, an amount per share equal to the greater of (i) the Series B original issuance price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series B redeemable convertible preferred stock been converted into shares of common stock immediately prior to such liquidation, dissolution, winding up or deemed liquidation event.

After the distribution to holders of Series B redeemable convertible preferred stock, the holders of the Series A redeemable convertible preferred stock shall be entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the holders of the common stock, an amount per share equal to the greater of (i) the Series A original issuance price, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series A redeemable convertible preferred stock been converted into shares of common stock immediately prior to such liquidation, dissolution, winding up or deemed liquidation event. Upon completion of the distribution to the holders of the redeemable convertible preferred stock, all remaining legally available assets will be distributed ratably to the holders of common stock.

Classification

The Company has classified its redeemable convertible preferred stock as temporary equity on the consolidated balance sheets as the stock is contingently redeemable. Upon the occurrence of certain deemed liquidation events that are outside of the Company’s control, including liquidation, sale, or transfer of the Company, holders of the redeemable convertible preferred stock can cause redemption for cash. During the years ended December 31, 2021 and 2020, the Company did not adjust the carrying value of the redeemable convertible preferred stock to the deemed liquidation value of such shares as a deemed liquidation event was not probable. Additionally, one investor that owns 2,435,016 shares of Series B redeemable convertible preferred stock are redeemable by the holder at the original issuance price in the event that the Company uses any of the proceeds received from such investor for purposes other than operations and research and development activities.

F-47

7. Common Stock

Holders of common stock are entitled to one vote per share, and to receive dividends and, upon liquidation or dissolution, are entitled to receive all assets available for distribution to stockholders. The holders have no preemptive or other subscription rights, and there are no redemption or sinking fund provisions with respect to such shares. Common stock is subordinate to the redeemable convertible preferred stock with respect to dividend rights and rights upon liquidation, winding up, and dissolution of the Company. Through December 31, 2021, no cash dividends have been declared or paid.

At December 31, 2021 and 2020, the Company was authorized to issue 138,000,000 shares of common stock, all at a par value of $0.0001 per share, and had reserved the following shares for future issuance:


	December 31,
	2021		2020
Series A and B redeemable convertible preferred stock		99,734,543		58,948,067
Stock options to purchase common stock		11,711,174		4,173,285
Common stock options available for future grant under stock option plan		3,666,927		12,857,369

Total		115,112,644		75,978,721

In addition to the stock options to purchase common stock in the above table, in association with the Business Combination Agreement with DYNS, the Company awarded certain performance and market awards with vesting contingent upon the consummation of the SPAC merger. See Note 9 - Stock-Based Compensation for further details.

8. Revenue

The Company’s revenue consists of amounts received related to research services provided to customers.

Contract Revenue

In May 2019, the Company entered into a collaborative development agreement. The Company determined that the agreement contained three distinct promises; research and development, design services, and intellectual property, which will be accounted for as a single combined performance obligation of research and development services recognized over time. The development agreement included $0.3 million of fixed consideration allocated to a single performance obligation and an additional $0.3 million of variable consideration. At inception of the development agreement, it was not probable that a significant reversal of revenue would not occur and therefore the variable consideration was fully constrained. Throughout the development agreement period, several parameters of the research and development services were changed, which increased the uncertainty of achieving the remaining performance obligations. Therefore, in December 2021, the contract asset of $0.3 million was reversed due to this increased uncertainty.

In April 2021, the Company entered into a research collaboration and license agreement with Spark Therapeutics, Inc. (“Spark”). Under the agreement, the Company will be responsible for a research program, which includes designing, building and testing five cell type specific-synthetic promoters for use in developing certain gene therapies using the Company’s proprietary technology. The Company received an upfront payment from Spark of $3.0 million and Spark is obligated to reimburse the Company for costs and expenses incurred for the research program. The Company expects to complete the research program over a two-year period.

The Company assessed this agreement in accordance with ASC 606, Revenue Recognition (“ASC 606”) and concluded that the contract counterparty, Spark, is a customer. The Company identified only one combined

F-48

performance obligation in the agreement, which is to perform research services, the related joint research plan and committees for the five specified promoters. The Company determined that the research activities for each of the five promoters are not distinct given there is one single research plan that is performed by the same research team and research results for one promoter may provide insights for other promoters.

Pursuant to the agreement, once the research program is completed and the Company delivers a data package to Spark, Spark has 24 months (the “evaluation period”) to determine whether Spark will exercise its options to obtain field-limited, royalty-bearing licenses to develop, manufacture and commercialize promoters corresponding to each of the five specified promoters being researched. For each licensed promoter option that is exercised, the Company is eligible to receive a license fee, potential research, development and commercial milestone payments and royalties on product sales. Spark may generally terminate the agreement upon 90 days’ prior written notice or 180 days’ prior written notice if the licensed promoter is in clinical trials or is being commercialized at the time of termination.

The Company evaluated Spark’s optional rights to license, develop, manufacture and commercialize each of the promoter profiles to determine whether they provide Spark with any material rights to purchase the promoter licenses at an incremental discount. The Company’s proprietary technology used to develop the promoters is in early stages of development, so technological feasibility and probability of developing a product is highly uncertain. As a result, determining the SSP for the optional rights is subject to significant judgment. Given the subjectivity associated with determining the SSP for the right to a future license related to unproven technology at contract inception, the Company also evaluated whether the contract consideration associated with the research services represents the SSP for those services. The Company determined the transaction price, inclusive of the upfront payment and reimbursement of costs and expenses incurred for the research program, is commensurate with SSP for the research being conducted given the specialized nature and reliance on proprietary technology. Based on the Company’s assessment of the optional consideration and the qualitative factors of feasibility and probability of development combined with the quantitative assessment that research services are priced at their SSP, the Company concluded that the license option does not provide Spark with an incremental discount and therefore does not constitute a material right. The transaction price associated with the research services in this agreement consists of the fixed upfront amount of $3.0 million and variable consideration.

For both collaboration agreements, the Company will recognize the transaction price as research and development services are provided, using a cost-based input method to measure the progress toward completion of its performance obligation and to calculate the corresponding amount of revenue to recognize each period. The Company believes that the cost-based input method is the best measure of progress because other measurements would not reflect how the Company transfers the control related to the performance obligation to our customers.

The Company has recorded nil and $0.2 million of revenue for the years ended December 31, 2021 and 2020, respectively, which was previously included in the deferred revenue balances at the beginning of each period. Contract asset balances related to unbilled revenue for our collaboration agreements were nil and $0.2 million as of December 31, 2021 and 2020, respectively, and are presented within prepaid expenses and other current assets on the consolidated balance sheets.

Grant Income

In 2018, the National Institutes of Health awarded the Company a grant in the amount of $0.2 million to be used to support research and development for treating Inflammatory Bowel Disease. Eligible costs under the grant include direct personnel costs and materials and supplies.

In 2021, the Small Business Innovation Research awarded the Company a grant in the amount of $2.0 million over two years subject to meeting certain terms and conditions. The purpose of the grant is to support further development of SENTI-202 for acute myeloid leukemia (“AML”) towards clinical development.

F-49

Grant income was recognized when qualified research and development costs were incurred and the Company obtained reasonable assurance that the terms and conditions of the grant were met.

Entity-wide information

During the year ended December 31, 2021, when excluding the $0.3 million contract asset reversal for Customer C, Customer A accounted for 84.3% of revenue, and Customer B accounted for 15.7% of revenue. During the year ended December 31, 2020, Customer B and C accounted for 30.4% and 69.6%, respectively, of revenue.

All net sales were generated in the United States for the years ended December 31, 2021 and 2020.

9. Stock-Based Compensation

In 2016, the Company adopted the 2016 Stock Incentive Plan (the “2016 Stock Incentive Plan”) authorizing the grant of incentive stock options (“ISOs”) and non-statutory stock options (“NSOs”) to eligible employees, officers and directors of, and consultants or advisors to, the Company. As of December 31, 2021, the Company is authorized to issue up to 65,551,165, respectively, of shares of common stock under the Plan in which the exercise price of an ISO and NSO shall not be less than 100% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. The exercise price of an ISO granted to a 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. Options generally vest over four years and are exercisable for up to 10 years after the date of the grant.

The following table summarizes the Company’s stock option activity, excluding performance and market awards:


	Number of Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value (in Thousands)
Outstanding at December 31, 2020		4,173,285		$	0.49		8.9	$	199

Granted		10,800,000		$	0.89
Exercised		(3,103,769	)	$	0.43
Forfeited		(158,342	)	$	0.65
Expired		—

Outstanding at December 31, 2021		11,711,174		$	0.86		9.1	$	11,304

Vested and exercisable at December 31, 2021		1,381,326		$	0.48		7.7	$	1,781

The aggregate intrinsic values of options exercised during the years ended December 31, 2021 and 2020 were $0.8 million and $0.2 million, respectively. The weighted-average grant-date fair values of options granted during the years ended December 31, 2021 and 2020 were $0.96 and $0.38, respectively.

Early Exercise of Stock Options into Restricted Stock

For the year ended December 31, 2021, the Company issued 2,619,677 shares of common stock upon exercise of unvested stock options, and as of December 31, 2021, 2,418,871 shares held by employees were subject to repurchase at an aggregate price of $1.2 million. As of December 31, 2020, no options were early exercised and accordingly, the liability related to the payments for unvested shares was nil at each date.

F-50

Stock-Based Compensation Expense

In determining the fair value of the stock-based awards, the Company uses the assumptions below for the Black-Scholes option pricing model, which are subjective and generally requires significant judgment.

Fair Value of Common Stock — The fair value of the shares of common stock has historically been determined by the Company’s board of directors as there was no public market for the common stock. The board of directors determines the fair value of the common stock by considering a number of objective and subjective factors, including: third-party valuations of the Company’s common stock, the valuation of comparable companies, the Company’s operating and financial performance, and general and industry-specific economic outlook, amongst other factors.

Expected Term — The expected term represents the period that the Company’s stock options are expected to be outstanding and is determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual term).

Volatility — Because the Company is privately held and does not have an active trading market for its common stock for a sufficient period of time, the expected volatility was estimated based on the average volatility for comparable publicly-traded companies, over a period equal to the expected term of the stock option grants.

Risk-free Rate — The risk-free rate assumption is based on the U.S. Treasury zero-coupon issues in effect at the time of grant for periods corresponding with the expected term of the option.

Dividends — The Company has never paid dividends on its common stock and does not anticipate paying dividends on common stock. Therefore, the Company uses an expected dividend yield of zero.

The assumptions used to determine the grant date fair value of stock options granted to grantees were as follows, presented on a weighted-average basis:


	Year Ended December 31,
	2021	2020
Expected term (in years)	6.03	6.03
Expected volatility	82.3%	83.3%
Risk-free interest rate	0.9%	0.7%
Dividend yield	— %	— %

Total stock-based compensation expense was as follows (in thousands):


	Year Ended December 31,
	2021		2020
General and administrative	$	1,940	$	201
Research and development		355		71

Total stock-based compensation expense	$	2,295	$	272

As of December 31, 2021, the total unrecognized stock-based compensation was approximately $9.2 million, which is expected to be recognized over a weighted-average period of 3.1 years.

Performance Awards

In connection with the Business Combination Agreement with DYNS, on December 19, 2021, the Company awarded 42,927,654 performance awards to existing employees that vest contingent upon the satisfaction of both a four-year service condition and a performance condition tied to the consummation of the SPAC merger. The

F-51

grant and the associated recognition of stock-based compensation is contingent on the SPAC merger being consummated which is subject to DYNS shareholder approval. As of December 31, 2021, 42,909,091 performance awards remain outstanding after the forfeiture of 18,563 performance awards during the year.

Market Awards

In connection with the Business Combination Agreement with DYNS, on December 19, 2021, the Company awarded 3,093,776 market awards to the co-founder and CEO, Mr. Lu that vest contingent upon the satisfaction of all three of the following conditions: a service condition, a performance condition tied to the consummation of the SPAC merger, and market conditions. The market condition is achieved in four tranches, where 25% of the options will vest when the trading price of the Company’s stock is above various thresholds of price per share. The grant and the associated recognition of stock-based compensation is contingent on the SPAC merger being consummated which is subject to DYNS shareholder approval.

10. Operating Leases

The Company’s operating leases are primarily for its corporate headquarters located in South San Francisco, California and for additional office and laboratory space located in Alameda, California (“Alameda lease”) that commenced on July 30, 2021. The corporate headquarters lease has an initial term of eight years expiring in 2027, with an option to renew for additional eight years unless canceled by either party thereafter. The Alameda lease has an initial term of eleven years expiring in 2032, with an option to renew the lease for up to two additional terms of five years. The exercise of these renewal options are not recognized as part of the ROU assets and lease liabilities, as the Company did not conclude, at the commencement date of the leases, that the exercise of renewal options or termination options was reasonably certain. The Alameda lease provides for a tenant improvement allowance of up to $17.5 million for the costs relating to the design, permitting and construction of the improvements, to be disbursed by the landlord no later than December 31, 2023. The Company was deemed to be the accounting owner of the tenant improvements primarily because the Company is the principal in the construction and design of the assets, is responsible for costs overruns and retains substantially all economic benefits from the leasehold improvements over their economic lives. Accordingly, the tenant improvement allowance is considered an incentive and was deducted from the initial measurement of the ROU asset and lease liability. The Company estimated the timing of tenant improvement reimbursements at the lease commencement date and upon receipt of the cash incentives, the Company will recognize the cash received as an increase in the lease liability.

The Company’s operating lease cost was $3.8 million and $2.7 million for the years ended December 31, 2021 and 2020, respectively. Variable lease payments such as common area maintenance and parking fees were included in operating expenses and were $0.7 million and $0.6 million for the years ended December 31, 2021 and 2020, respectively. The Company did record any short-term lease expense during the years ended December 31, 2021 and 2020. No reimbursements have been received from the landlord as of December 31, 2021 and 2020.

Supplemental cash flow and noncash information related to the operating leases were as follows (in thousands):

11. Income Taxes

For the calendar years ended December 31, 2021 and 2020, the tax effects of significant items comprising the Company’s deferred taxes are as follows:


	December 31,
	2021			2020
Deferred tax assets:
Net operating losses	$	23,104		$	15,543
Tax credits		4,915			2,775

Total deferred tax liabilities		(6,025	)		(3,768	)
Valuation allowance		(29,710	)		(19,025	)

Net deferred taxes	$	—		$	—

The Company records the tax benefit of net operating losses, temporary differences, and credit carryforwards as assets to the extent that management assesses that realization is “more likely than not.”

F-53

Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance.

The valuation allowance increased by approximately $10.7 million and $7.9 million during 2021 and 2020, respectively, and the Company’s deferred tax assets continue to be fully offset by the valuation allowance as at December 31, 2021. For the years ended December 31, 2021 and 2020, the Company did not record an income tax provision.

Net operating losses and tax credit carryforwards as of December 31, 2021 are as follows (in thousands):


	Amount		Expiration Years
Net operating losses, federal (Post December 31, 2017)	$	86,602		Do Not Expire
Net operating losses, federal (Pre January 1, 2018)	$	3,508		12/31/2031
Net operating losses, state	$	55,023		12/31/2032
Tax credits, federal	$	3,573		12/31/2032
Tax credits, state	$	3,120		Do Not Expire
Net operating losses, foreign	$	1,146		Do Not Expire

Utilization of the net operating loss carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. This annual limitation may result in the expiration of net operating losses and credits before utilization. We have not performed an analysis to determine the limitation of our net operating loss carryforwards.

The effective tax rate of the Company’s provision (benefit) for income taxes differs from the federal statutory rate as follows:


	December 31,
	2021			2020
Statutory rate		21.00	%		21.00	%
State tax		2.98	%		11.68	%
Other		(0.80	)%		(0.05	)%
Tax credits		2.29	%		2.81	%
Fair value of series B preferred stock tranche liability		(5.60	)%		6.04	%
Valuation allowance		(19.87	)%		(41.48	)%

Total		0.00	%		0.00	%

As of December 31, 2020, gross unrecognized tax benefits were $1.3 million, all of which would not impact the Company’s effective tax rate if recognized. The Company has elected to include interest and penalties as a component of tax expense. For the years ended December 31, 2021 and 2020, the Company did not recognize accrued interest and penalties related to unrecognized tax benefits. The Company does not anticipate that the amount of existing unrecognized tax benefits will significantly increase or decrease during the next 12 months.

The Company files income tax returns in the U.S. federal and California tax jurisdictions. The federal and state income tax returns from inception to December 31, 2021 remain subject to examination.

12. Net Loss Per Share

A reconciliation of net loss available to common stockholders and the number of shares in the calculation of basic and diluted loss per share is as follows:

The following potential common shares securities were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been anti-dilutive (on an as-converted basis):


	Year Ended December 31,

In the ordinary course of business, we enter into contractual agreements with third parties that include non-cancelable payment obligations, for which we are liable in future periods.

On June 3, 2021, the Company entered into a lease agreement for a new cGMP facility in Alameda, California to support planned initial clinical trials for our product candidates (Note 10). The lease will expire in 2032 with future undiscounted operating lease payments of $46.0 million over an initial lease period of eleven years.

In 2021, the Company began construction of the cGMP facility. As of December 31, 2021 the Company paid $2.6 million in construction costs and the purchase commitments amounted to approximately $35.5 million. The agreements with the construction company provide for termination following a certain period after notice. Upon termination the Company will be responsible for payment for work performed to date.

During the year ended December 31, 2021, the Company entered into a three-year collaboration and option agreement with BlueRock Therapeutics LP (“BlueRock”) under which the Company granted BlueRock an option to acquire an exclusive or non-exclusive license to develop, manufacture and commercialize cell therapy products (Note 14). In consideration for the option, the Company is responsible for up to $10.0 million in costs and expenses incurred over the three-year term.

F-55

As of December 31, 2021, purchase commitments related to sponsored research agreements amounted to approximately $2.2 million.

The Company has entered into license agreements under which they are obligated to make annual maintenance payments of $0.1 million and specified milestone and royalty payments. Future milestone and royalty payments under these agreements are not considered contractual obligations since the payments under these agreements are contingent upon future events, such as the Company’s achievement of specified development, regulatory, and sales milestones, or generating product sales. As of December 31, 2021, the Company is unable to estimate the timing or likelihood of achieving these milestones or generating future product sales.

Leases

The Company’s commitments under its leases are described in Note 10.

Legal Proceedings

The Company is subject to claims and assessments from time to time in the ordinary course of business but does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s financial position, results of operations, or cash flows.

Indemnifications

In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions and has never accrued any liabilities related to such obligations in its consolidated financial statements. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by Delaware corporate law. The Company currently has directors’ and officers’ insurance.

14. Related Parties

As discussed in Note 6, the Company issued Series A convertible redeemable preferred stock and Series B redeemable convertible preferred stock in February 2018 and October 2020, respectively, to certain related parties, including New Enterprise Associates 15, L.P. and its affiliates (“NEA”) and 8VC and its affiliates (“8VC”).

In February 2018, the outstanding convertible notes held by NEA and 8VC, as well as Timothy Lu, Chief Executive Officer, converted into additional shares of Series A redeemable convertible preferred stock while in October 2020, the outstanding convertible notes held by NEA and 8VC converted into additional shares of Series B redeemable convertible preferred stock, both in accordance with the terms of the note agreements.

NEA held 13,505,035 shares of outstanding Series A redeemable convertible preferred stock as of December 31, 2021 and 2020, as well as 2,742,931 of outstanding Series B redeemable convertible preferred stock as of December 31, 2021 and 2020. 8VC held 9,052,387 of outstanding Series A redeemable convertible preferred stock as of December 31, 2021 and 2020 as well as 1,662,398 of outstanding Series B redeemable convertible preferred stock as of December 31, 2021 and 2020. Timothy Lu held 158,950 of outstanding

F-56

redeemable convertible preferred stock as of December 31, 2021 and 2020. Timothy Lu and family held 8,100,000 of common stock as of December 31, 2021 and 2020. Timothy Lu, NEA, and 8VC held three of the seven seats on the Company’s Board of Directors as of December 31, 2021 and three of the five seats on the Company’s Board of Directors as of December 31, 2020.

As Chief Executive Officer, Timothy Lu was paid $0.4 million as compensation, and an additional sum of $0.2 million was accrued as a bonus for both the years ended December 31, 2021 and 2020.

On May 21, 2021, the Company entered into a collaboration and option agreement (“BlueRock Agreement”) with BlueRock Therapeutics LP (“BlueRock”), pursuant to which the Company granted to BlueRock an option (“BlueRock Option”), on a collaboration program-by-collaboration program basis, to obtain an exclusive or non-exclusive license to develop, manufacture and commercialize cell therapy products that contain cells of specified types and which incorporate an option gene circuit from such collaboration program or a closely related derivative gene circuit. The Company is responsible for up to $10 million in costs and expenses incurred in connection with the research plan and related activities to be conducted over a term of three years as specified in the collaboration and option agreement. If the Company and BlueRock agree to add new research activities to the research plan, then BlueRock will be obligated to reimburse the Company for the costs and expenses incurred that, together with costs and expenses incurred under the initial research plan, exceed $10 million.

The Company concluded that the Agreement is not within the scope of ASC 808, Collaborative Arrangements, because the Company did not receive any consideration and therefore, is not exposed to both significant risks and rewards for the arrangement. The Company also determined that the agreement is also not currently within the scope of ASC 606 because the BlueRock Agreement does not currently meet the criteria of a contract with a customer, and will not be within scope of ASC 606 until any consideration is paid. Potential future milestone payments and royalties are subject to BlueRock’s exercise of the BlueRock Option and execution of a commercial license agreement by both parties. Under the BlueRock Agreement, the specific financial terms for milestone payments and royalties will be negotiated and agreed to only after the option is exercised.

BlueRock is a wholly-owned subsidiary of Bayer Healthcare LLC which held 27,393,924 and 9,131,308 shares of outstanding Series B redeemable convertible preferred stock as of December 31, 2021 and 2020, respectively, and holds one of the seven seats on the Company’s Board of Directors as of December 31, 2021 and one of the five seats as of December 31, 2020. Bayer Healthcare LLC’s parent company is Bayer AG, which served as the lead investor in our Series B financing through its Leaps by Bayer unit. Accordingly, BlueRock is considered a related party. The Company concluded that the BlueRock Agreement should not be combined with the issuance of the Series B redeemable convertible preferred stock on May 14, 2021 as the price paid per share of $1.6427 was lower than the fair value of $2.03 (Note 3) and therefore, there was no excess value to allocate to the BlueRock Agreement.

15. Subsequent Events

The Company has evaluated subsequent events from the December 31, 2021 balance sheet date through April 1, 2022, the date at which the audited consolidated financial statements were available to be issued.

Option Modification

On February 12, 2022, the Company entered into Amendment No. 1 to the Business Combination Agreement, to restructure the performance and market awards made at the time the Business Combination Agreement was signed. In particular, certain Senti executives agreed to forfeit certain options awarded to them at the time the Business Combination Agreement was signed depending on the level of redemptions of DYNS Class A Common Stock upon closing of the merger. In addition, it was agreed that the vesting period for the options held by executives whose options may be subject to forfeiture (as described above) will commence upon closing of the merger instead of on December 19, 2021.

(a) Merger.

(i) On the terms and subject to the conditions set forth in this Agreement and in accordance with the DGCL, on the Closing Date, Merger Sub shall merge with and into the Company at the Effective Time. Following the Effective Time, the separate existence of Merger Sub shall cease and the Company shall continue as the surviving company of the Merger (the “Surviving Corporation”).

A-16

(ii) At the Closing, the Parties shall cause a certificate of merger, in a form reasonably satisfactory to the Company and DYNS (the “Certificate of Merger”), to be executed and filed with the Secretary of State of the State of Delaware. The Merger shall become effective on the date and time at which the Certificate of Merger is accepted for filing by the Secretary of State of the State of Delaware or at such later date or time as is agreed by DYNS and the Company and specified in the Certificate of Merger (the time the Merger becomes effective being referred to herein as the “Effective Time”).

(iii) The Merger shall have the effects set forth in Section 251 of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all of the assets, properties, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation and all Liabilities, obligations, restrictions, disabilities and duties of or applicable to each of the Company and Merger Sub shall become the Liabilities, obligations, restrictions, disabilities and duties of or applicable to the Surviving Corporation, in each case, in accordance with the DGCL.

(iv) At the Effective Time, the Governing Documents of Merger Sub shall be the Governing Documents of the Surviving Corporation, in each case, until thereafter changed or amended as provided therein or by applicable Law.

(v) At the Effective Time, the directors and officers of the Company immediately prior to the Effective Time shall be the initial directors and officers of the Surviving Corporation, each to hold office in accordance with the Governing Documents of the Surviving Corporation until such director’s or officer’s successor is duly elected or appointed and qualified, or until the earlier of their death, resignation or removal.

(vi) At the Effective Time, by virtue of the Merger and without any action on the part of any Party or any other Person, each share of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock, par value $0.0001, of the Surviving Corporation.

(vii) At the Effective Time, by virtue of the Merger and without any action on the part of any Party or any other Person, each Company Share (other than the Company Shares cancelled in accordance with clause (viii) immediately below) issued and outstanding as of immediately prior to the Effective Time shall be canceled and extinguished and be converted into the right to receive a number of shares of Class A Common Stock equal to the Merger Consideration. From and after the Effective Time, the holder(s) of certificates (the “Certificates”), if any, evidencing ownership of Company Shares and the Company Shares held in book-entry form issued and outstanding immediately prior to the Effective Time shall each cease to have any rights with respect to such Company Shares except as otherwise expressly provided for herein or under applicable Law.

(viii) At the Effective Time, by virtue of the Merger and without any action on the part of any Party or any other Person, each Company Share held immediately prior to the Effective Time by the Company as treasury stock shall be canceled and extinguished, and no consideration shall be paid with respect thereto.

Section 2.2 Contingency Consideration.

(a) Following the Closing, in addition to the consideration to be received pursuant to Sections 2.1(a)(vii) and 2.5 and as part of the overall Aggregate Consideration, Company Stockholders shall be issued additional shares of Class A Common Stock, as follows:

(i) one million (1,000,000) shares of Class A Common Stock, in the aggregate, if, on or before the date which is two (2) calendar years after the Closing Date (the “First Outside Date”), the volume weighted average price of shares of Class A Common Stock on Nasdaq, or any other national securities exchange on which the shares of Class A Common Stock are then traded (“VWAP”), is greater than or equal to fifteen dollars ($15.00) over any twenty (20) trading days within any consecutive thirty (30) trading day period (the

A-17

“First Share Target”) (such 1,000,000 shares of Class A Common Stock, the “First Level Contingency Consideration”); and

(ii) one million (1,000,000) shares of Class A Common Stock, in the aggregate, if, on or before the date which is three (3) calendar years after the Closing Date (the “Second Outside Date” and, together with the First Outside Date, the “Outside Dates”), the VWAP is greater than or equal to twenty dollars ($20.00) over any twenty (20) trading days within any consecutive thirty (30) trading day period (the “Second Share Target” and, together with the First Share Target, the “Share Targets”) (such 1,000,000 shares of Class A Common Stock, the “Second Level Contingency Consideration” and, together with the First Level Contingency Consideration, the “Contingency Consideration”). For the avoidance of doubt, each of the First Level Contingency Consideration and the Second Level Contingency Consideration is issuable only once in accordance with the terms of this Section 2.2(a), and the maximum amount of Contingency Consideration is two million (2,000,000) shares of Class A Common Stock, in the aggregate.

(b) If either of the Share Targets shall have been achieved, then within ten (10) Business Days following the achievement of the applicable Share Target (which may be achieved at the same time or over the same or overlapping trading days), DYNS shall issue the applicable Contingency Consideration to each Company Stockholder as specified on the Allocation Schedule.

(c) Following the Closing, if a Change of Control of DYNS shall occur on or before the applicable Outside Date set forth in Section 2.2(a)(i) or Section 2.2(a)(ii), respectively, then if (i) the per share value of the consideration to be received by holders of Class A Common Stock in connection with the Change of Control exceeds $15.00 per share and the First Share Target has not been previously achieved, then the First Share Target shall be deemed to have been achieved, and (ii) the per share value of the consideration to be received by holders of Class A Common Stock in connection with the Change of Control exceeds $20.00 per share and the Second Share Target has not been previously achieved, then the Second Share Target shall be deemed to have been achieved. If either or both Share Targets are deemed to have been achieved, then any Contingency Consideration that remains unissued as of immediately prior to the consummation of such Change of Control shall immediately become payable and the Company Stockholders shall be entitled to receive such Contingency Consideration prior to the consummation of such Change of Control; provided, that any Contingency Consideration that is not deemed to be earned in connection with the Change of Control in accordance with this Section 2.2(c) shall be forfeited by the Company Stockholder(s) for no consideration. Any Contingency Consideration shall be payable to the Company Stockholders as specified on the Allocation Schedule. For the purposes of this Agreement, a “Change of Control” shall have been deemed to occur with respect to DYNS upon:

(i) the sale, lease, license, distribution, dividend or transfer, in a single transaction or a series of related transactions, of more than fifty percent (50%) of the assets of DYNS and its Subsidiaries taken as a whole; or

(ii) a merger, consolidation or other business combination of DYNS (or any Subsidiary or Subsidiaries that alone or together represent more than fifty percent (50%) of the consolidated business of DYNS at that time) or any successor or other entity holding, directly or indirectly, fifty percent (50%) or more of all the assets of DYNS and its Subsidiaries that results in the stockholders of DYNS (or such Subsidiary or Subsidiaries) or any successor or other entity holding, directly or indirectly, fifty percent (50%) or more of the assets of DYNS and its Subsidiaries or the surviving entity thereof, as applicable, immediately before the consummation of such transaction or series of related transactions holding, directly or indirectly, less than fifty percent (50%) of the voting power of DYNS (or such Subsidiary or Subsidiaries) or any successor, other entity or surviving entity thereof, as applicable, immediately following the consummation of such transaction or series of related transactions.

(d) The Contingency Consideration and the Share Targets shall be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into shares of Class A Common Stock), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Class A Common Stock, occurring on or

A-18

after the date hereof and prior to the time any such Contingency Consideration is delivered to the Company Stockholders, if any.

(e) The right of the Company Stockholders to receive the Contingency Consideration (i) is solely a contractual right and will not be evidenced by a certificate and does not constitute a security or other instrument, (ii) may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than upon written notice to DYNS pursuant to a Permitted Transfer, and (iii) does not give the Company Stockholders any right to receive interest payments. There is no guaranty or other assurance of any kind that any Contingency Consideration will be payable hereunder (regardless of any projections, models, forecasts or any other financial data generated by, or provided to, the Company, DYNS or their respective Affiliates or Representatives). For purposes of this Agreement, “Permitted Transfer” means (A) a transfer on death by will or intestacy, (B) a transfer by instrument to an inter vivos or testamentary trust for beneficiaries upon the death of the trustee, (C) a transfer made pursuant to an order of a court of competent jurisdiction (such as in connection with divorce, bankruptcy or liquidation), (D) a transfer by a partnership or limited liability company through a distribution to its partners or members, as applicable, in each case without consideration, or (E) a transfer made by operation of law (including a consolidation or merger) or as pursuant to the dissolution, liquidation or termination of any corporation, limited liability company, partnership or other entity.

(f) If the consideration to be received by holders of Class A Common Stock in a Change of Control includes non-cash consideration, then the value of such consideration for the purposes of Section 2.2(c) shall be determined in good faith by the DYNS Board.

Section 2.3 Closing of the Transactions Contemplated by this Agreement. The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of Goodwin Procter LLP, 620 Eighth Avenue, New York, NY 10018 as promptly as reasonably practicable, but in no event later than the third (3^rd) Business Day, following the satisfaction (or, to the extent permitted by applicable Law, waiver) of the conditions set forth in Article 6 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to satisfaction or waiver of such conditions) (the “Closing Date”) or at such other place, date or time as DYNS and the Company may agree in writing, or electronically by exchange of the closing deliverables by the means provided in Section 8.11.

Section 2.4 Allocation Schedule. No later than five (5) Business Days prior to the Closing Date, the Company shall deliver to DYNS an allocation schedule (the “Allocation Schedule”) setting forth (a) the number of Equity Securities held by each Company Stockholder, the number of shares of Company Common Stock subject to each Company Option held by each holder thereof, as well as whether each such Company Option will be a Vested Company Option or an Unvested Company Option as of immediately prior to the Effective Time, and, in the case of the Company Options, the exercise price thereof, as well as reasonably detailed calculations with respect to the components and subcomponents thereof, (b) the number of shares of Class A Common Stock that will be subject to each Rollover Option and the exercise price of each such Rollover Option at the Effective Time, in each case, determined in accordance with Section 2.5, as well as reasonably detailed calculations with respect to the components and subcomponents thereof, (c) the portion of the Transaction Share Consideration allocated to each Company Stockholder pursuant to Section 2.1(a)(vii), as well as reasonably detailed calculations with respect to the components and subcomponents thereof, (d) the portion of the Contingency Consideration allocated to each Company Stockholder, in the event that any Contingency Consideration becomes payable, as well as reasonably detailed calculations with respect to the components and subcomponents thereof, and (e) a certification, duly executed by an authorized officer of the Company, that the information and calculations delivered pursuant to clauses (a), (b), (c) and (d) are, and will be as of immediately prior to the Effective Time, (i) true and correct in all respects, and (ii) in accordance with the applicable provisions of this Agreement, the Governing Documents of the Company and applicable Laws and, in the case of Company Options, the Company Equity Plan and any applicable grant or similar agreement with respect to any such Company Option. The Company will review any comments to the Allocation Schedule provided by DYNS or any of its Representatives and consider in good faith and incorporate any reasonable comments proposed by

A-19

DYNS or any of its Representatives to correct inaccuracies. Notwithstanding the foregoing or anything to the contrary herein, the aggregate number of shares of Class A Common Stock that each Company Stockholder will have a right to receive pursuant to Section 2.1(a)(vii) will be rounded down to the nearest whole share.

Section 2.5 Treatment of Company Options.

(a) At the Effective Time, by virtue of the Merger and without any action of any Party or any other Person (but subject to, in the case of the Company, Section 2.5(c)), each Company Option (whether a Vested Company Option or an Unvested Company Option) shall cease to represent the right to purchase shares of Company Common Stock and shall be converted into an option to purchase shares of Class A Common Stock (each, a “Rollover Option”) in an amount, at an exercise price and subject to such terms and conditions determined as set forth below. Each Rollover Option shall (i) be exercisable for, and represent the right to purchase, a number of shares of Class A Common Stock (rounded down to the nearest whole share) equal to (A) the number of shares of Company Common Stock subject to the corresponding Company Option immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, and (ii) have an exercise price per share of Class A Common Stock (rounded up to the nearest whole cent) subject to such Rollover Option equal to (A) the exercise price per share of Company Common Stock applicable to the corresponding Company Option immediately prior to the Effective Time, divided by (B) the Exchange Ratio. Each Rollover Option shall be subject to the same terms and conditions (including applicable vesting, expiration and forfeiture provisions) that applied to the corresponding Company Option immediately prior to the Effective Time, except for terms rendered inoperative by reason of the transactions contemplated by this Agreement or the Ancillary Documents or for such other immaterial administrative or ministerial changes as the DYNS Board (or the compensation committee of the DYNS Board) may determine in good faith are appropriate to effectuate the administration of the Rollover Options. Such conversion shall occur in a manner intended to comply with (x) for any Rollover Option that is an Incentive Stock Option, the requirements of Section 424 of the Code, and (y) in each case, the requirements of Section 409A of the Code.

(b) At the Effective Time, DYNS shall assume the Company Equity Plan and (i) all Company Options (whether vested or unvested) shall no longer be outstanding and shall automatically be converted into Rollover Options, and each holder thereof shall cease to have any rights with respect thereto or under the Company Equity Plan, except as otherwise expressly provided for in this Section 2.5, and (ii) all shares of Company Common Stock reserved for issuance pursuant to the Company Equity Plan shall automatically be cancelled.

(c) Prior to the Closing, the Company shall take, or cause to be taken, all necessary or appropriate actions under the Company Equity Plan (and the underlying grant, award or similar agreements) or otherwise to give effect to the provisions of this Section 2.5.

Section 2.6 Closing Actions and Deliverables.

(a) At least five (5) Business Days prior to the Closing Date, DYNS shall appoint an exchange agent reasonably acceptable to the Company (the “Exchange Agent”) (it being understood and agreed, for the avoidance of doubt, that Continental Stock Transfer & Trust Company shall be deemed to be acceptable to the Company) and enter into an exchange agent agreement with the Exchange Agent (the “Exchange Agent Agreement”) for the purpose of exchanging Certificates, if any, representing the Company Shares, and each Company Share held in book-entry form on the stock transfer books of the Company immediately prior to the Effective Time, for the portion of the Merger Consideration issuable in respect of such Company Share pursuant to Section 2.1(a)(vii), and on the terms and subject to the other conditions set forth in this Agreement.

(b) At least three (3) Business Days prior to the Closing Date, the Company shall mail or otherwise deliver, or shall cause to be mailed or otherwise delivered, to the Company Stockholders a letter of transmittal in a customary form to be mutually agreed between the Parties (a “Letter of Transmittal”); provided that any representations and warranties made by a Company Stockholder in a Letter of Transmittal shall be limited to authority, title to the applicable Company Shares and absence of Liens on the applicable Company Shares.

All shares in book-entry form representing the portion of the Merger Consideration issuable pursuant to Section 2.1(a)(vii) deposited with the Exchange Agent shall be referred to in this Agreement as the “Exchange Fund”.

(d) Each Company Stockholder whose Company Shares have been converted into the right to receive a portion of the Merger Consideration pursuant to Section 2.1(a)(vii) shall be entitled to receive the portion of the Merger Consideration to which he, she or it is entitled on the date provided in Section 2.6(e) upon (i) surrender of a Certificate (or affidavit of loss, in lieu thereof, in the form required by the Letter of Transmittal), together with the delivery of a properly completed and duly executed Letter of Transmittal (including, for the avoidance of doubt, any documents or agreements required by the Letter of Transmittal), to the Exchange Agent, or (ii) delivery of an “agent’s message” in the case of Company Common Stock held in book-entry form, together with the delivery of a properly completed and duly executed Letter of Transmittal (including, for the avoidance of doubt, any documents or agreements required by the Letter of Transmittal), to the Exchange Agent.

(e) If a properly completed and duly executed Letter of Transmittal, together with any Certificates (or affidavit of loss, in lieu thereof, in the form required by the Letter of Transmittal) or an “agent’s message”, as applicable, is delivered to the Exchange Agent in accordance with Section 2.6(d) (i) at least one (1) Business Day prior to the Closing Date, then DYNS and the Company shall take all necessary actions to cause the applicable portion of the Merger Consideration to be issued to the applicable Company Stockholder in book-entry form on the Closing Date, or (ii) less than one (1) Business Day prior to or on or after the Closing Date, then DYNS and the Company (or the Surviving Corporation) shall take all necessary actions to cause the applicable portion of the Merger Consideration to be issued to the Company Stockholder in book-entry form within two (2) Business Days after such delivery.

(f) If any portion of the Merger Consideration is to be issued to a Person other than the Company Stockholder in whose name the surrendered Certificate is, or the transferred Company Shares in book-entry form are, registered, it shall be a condition to the issuance of the applicable portion of the Merger Consideration that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer, or such Company Shares in book-entry form shall be properly transferred, and (ii) the Person requesting such consideration pay to the Exchange Agent any transfer or similar Taxes required as a result of such consideration being issued to a Person other than the registered holder of such Certificate or Company Shares in book-entry form, or establish to the satisfaction of the Exchange Agent that such transfer or similar Taxes have been paid or are not payable.

(g) No interest will be paid or accrued on the Merger Consideration (or any portion thereof). From and after the Effective Time, until surrendered or transferred, as applicable, in accordance with this Section 2.6, each Company Share (other than, for the avoidance of doubt, the Company Shares cancelled in accordance with Section 2.1(a)(viii)) shall solely represent the right to receive a portion of the Merger Consideration to which such Company Share is entitled pursuant to Section 2.1(a)(vii).

(h) At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no transfers of Company Shares that were outstanding immediately prior to the Effective Time.

(i) Any portion of the Exchange Fund that remains unclaimed by the Company Stockholders twelve (12) months following the Closing Date shall be delivered to DYNS or as otherwise instructed by DYNS, and any Company Stockholder who has not exchanged his, her or its Company Shares for the applicable portion of the Merger Consideration in accordance with this Section 2.6 prior to that time shall thereafter look only to DYNS for the issuance of the applicable portion of the Merger Consideration, without any interest thereon. None of DYNS, the Surviving Corporation or any of their respective Affiliates shall be liable to any Person in respect of any consideration delivered to a public official pursuant to any applicable abandoned property, unclaimed property, escheat or similar Law. Any portion of the Merger Consideration remaining unclaimed by the Company Stockholders immediately prior to such time when the amounts would otherwise escheat to or become property

A-21

DYNS, the Exchange Agent and any of their Affiliates shall be entitled to deduct and withhold (or cause to be deducted and withheld) from any consideration payable pursuant to this Agreement such amounts as are required to be deducted and withheld under applicable Tax Law. To the extent that amounts are so withheld and remitted to the applicable Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. Upon becoming aware of any such withholding obligation, DYNS shall use commercially reasonable efforts to give reasonable advance notice of such withholding to the Company (other than where such deduction or withholding is in respect of amounts treated as compensation under the Code or is due to a failure of a Person to provide an any applicable tax forms required under the Letter of Transmittal (or properly claim an exemption in respect of backup withholding on such tax forms)) and shall reasonably cooperate with the Company, to eliminate or reduce any such required deduction or withholding.

Each of the Parties hereto shall use reasonable best efforts to ensure that none of the information related to it or any of its Representatives, supplied by or on its behalf for inclusion or incorporation by reference in the Registration Statement/Proxy Statement will, at the time the Registration Statement/Proxy Statement is filed with the SEC, at each time at which it is amended, or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.

During such six (6)-year period, DYNS shall advance, or caused to be advanced, expenses in connection with such indemnification as provided in the applicable DYNS Party’s Governing Documents or other applicable agreements in effect as of the date hereof. The advancement, indemnification and liability limitation or exculpation provisions of the DYNS Parties’ Governing Documents or in other applicable agreements in effect as of immediately prior to the Effective Time shall not, during such six (6)-year period, be amended, repealed or otherwise modified after the Effective Time in any manner that would materially and adversely affect the rights thereunder of individuals who, as of immediately prior to the Effective Time or at any time prior to such time, were directors or officers of any DYNS Party (the “DYNS D&O Persons”) to receive advancement, be so indemnified, have their liability limited or be exculpated with respect to any act, error or omission occurring on or prior to the Effective Time by reason of the fact that such DYNS D&O Person was a director or officer of any DYNS Party prior to the Effective Time, unless such amendment, repeal or other modification is required by applicable Law.

(b) DYNS shall not have any obligation under this Section 5.14 to any DYNS D&O Person when and if a court of competent jurisdiction shall ultimately determine (and such determination shall have become final and non-appealable) that the indemnification of such DYNS D&O Person in the manner contemplated hereby is prohibited by applicable Law.

(b) None of DYNS, the Company or any of its Subsidiaries shall have any obligation under this Section 5.15 to any Company D&O Person when and if a court of competent jurisdiction shall ultimately determine (and such determination shall have become final and non-appealable) that the indemnification of such Company D&O Person in the manner contemplated hereby is prohibited by applicable Law.

(c) The Company shall purchase, at or prior to the Effective Time, and DYNS shall maintain, or cause to be maintained, in effect for a period of six (6) years after the Effective Time, without lapses in coverage, a “tail” policy or policies providing directors’ and officers’ liability insurance coverage for the benefit of those Persons who are currently covered by any comparable insurance policies of the Company or its Subsidiaries immediately prior to the Effective Time with respect to any acts, errors or omissions occurring on or prior to the Effective Time (the “Company D&O Tail Policy”). Such Company D&O Tail Policy shall provide coverage on terms

A-59

(with respect to coverage and amount) that are substantially the same as (and no less favorable in the aggregate to the insured than) the coverage provided under the Company’s or its Subsidiaries’ directors’ and officers’ liability insurance policies in effect immediately prior to the Effective Time; provided that the Company shall not pay a premium for such “tail” policy or policies in excess of three hundred fifty percent (350%) of the most recent premium paid by the Company or its Subsidiary prior to the Effective Time and, if the requisite cover is not available for such a premium, the Company shall purchase the maximum coverage available for three hundred fifty percent (350%) of the most recent premium paid by the Company prior to the Effective Time. Notwithstanding the foregoing in this Section 5.15(c), the Company in its sole discretion, in lieu of purchasing the Company D&O Tail Policy, may choose to maintain (and if so chosen, DYNS shall maintain or cause to be maintained) for a period of six (6) years after the Closing, without any lapses in coverage, directors’ and officers’ liability insurance for the benefit of those Persons who are currently covered by any comparable insurance policies of the Company and its Subsidiaries immediately prior to the Effective Time with respect to any acts, errors or omissions occurring on or prior to the Effective Time. Such insurance policies shall provide coverage on terms (with respect to coverage and amount) that are substantially the same as (and no less favorable in the aggregate to the insured than) the coverage provided under the Company’s or its Subsidiaries’ directors’ and officers’ liability insurance policies immediately prior to the Effective Time.

(e) The Company D&O Persons entitled to the advancement, indemnification, liability limitation, exculpation and insurance set forth in this Section 5.15 are intended to be third-party beneficiaries of this Section 5.15.

Section 5.22 Section 280G.

Prior to the Closing Date, the Company shall solicit shareholder approval of all Waived 280G Payments in a manner intended to satisfy all applicable requirements of Section 280G(b)(5)(B) of the Code and the Treasury Regulations promulgated thereunder. The form and substance of all stockholder approval documents contemplated by this Section 5.22, including the waivers, shall be subject to the prior review and reasonable approval of DYNS.

During the Interim Period and subject to applicable law, the Company will use commercially reasonable efforts to obtain from all Company Stockholders, who have not previously entered into a Company Support Agreement or Major Holder Support Agreement on the date hereof, Company Support Agreements in the form attached hereto as Exhibit C prior to the Closing.

The Parties agree that irreparable damage, for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their respective obligations under the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate the transactions contemplated by this Agreement) in accordance with their specific terms or otherwise breach such provisions. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case, without posting a bond or undertaking and without proof of damages, and this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that (a) the other Parties have an adequate remedy at law, or (b) an award of specific performance is not an appropriate remedy for any reason at law or in equity.

Section 8.18 Trust Account Waiver. Reference is made to the final prospectus of DYNS, filed with the SEC (File No. 333-255930) on May 27, 2021 (the “Prospectus”). The Company acknowledges, agrees and understands that DYNS has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of DYNS’s public stockholders (the “Public Stockholders”) and certain other parties (including the underwriters of the IPO), and DYNS may disburse monies from the Trust Account only in the express circumstances described in the Prospectus. For and in consideration of DYNS entering into this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company hereby agrees on behalf of itself and its Representatives and Affiliates that, notwithstanding anything to the contrary in this Agreement, none of the Company nor any of its Representatives or Affiliates does now nor shall at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account or distributions therefrom, and shall not make or bring any action, suit, claim or other proceeding against the Trust Account (including in respect of any distributions therefrom), regardless of whether such action, suit, claim or other proceeding arises as a result of, in connection with or relates in any way to, this Agreement, the transactions contemplated hereby or

A-71

any proposed or actual business relationship between DYNS or any of its Representatives of Affiliates, on the one hand, and the Company or any of its Representatives or Affiliates, on the other hand, or any other matter, and regardless of whether such action, suit, claim or other proceeding arises based on contract, tort, equity or any other theory of legal liability (any and all such actions, suits, claims or other proceedings are collectively referred to hereafter as the “Trust Account Released Claims”). The Company, on its own behalf and on behalf of its Representatives and Affiliates, hereby irrevocably and unconditionally waives any Trust Account Released Claims that it or any of its Representatives or Affiliates may have against the Trust Account (including in respect of any distributions therefrom) now or in the future as a result of, or arising out of, any discussions, negotiations, agreements or Contracts with DYNS or its Representatives or Affiliates, and will not seek recourse against the Trust Account (including in respect of any distributions therefrom) for any reason whatsoever (including for an alleged breach of any agreement with DYNS or its Affiliates).

2.1.1 Registration Statement Covering Resale of Registrable Securities. Provided compliance by the Investors with Section 3.4, the Company shall prepare and file or cause to be prepared and filed with the Commission, as soon as reasonably practical, but in no event later than twenty (20) calendar days following the Closing Date, a Registration Statement on Form S-3 or its successor form, or, if the Company is ineligible to use Form S-3, a Registration Statement on Form S-1, for an offering to be made on a continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by Investors of all of the Registrable

A-5

Securities then held by such Investors that are not covered by an effective resale registration statement (the “Resale Shelf Registration Statement”). The Company shall use commercially reasonable efforts to cause the Resale Shelf Registration Statement to be declared effective as soon as possible after filing, and in no event later than the earlier of (x) 60^th calendar day after the Closing (or 90^th calendar day if the SEC notifies (orally or in writing, whichever is earlier) the Company that it will “review” the Resale Shelf Registration Statement) and, (y) the 5^th Business Day after the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Resale Shelf Registration Statement will not be “reviewed” or will not be subject to further review. Once effective the Company shall use commercially reasonable efforts to keep the Resale Shelf Registration Statement continuously effective under the Securities Act at all times until the expiration of the Effectiveness Period (as defined below). In the event that the Company files a Form S-1 pursuant to this Section 2.1, the Company shall use its commercially reasonable efforts to convert the Form S-1 to a Form S-3 promptly after the Company is eligible to use Form S-3. The Resale Shelf Registration Statement shall provide that the Registrable Securities may be sold pursuant to any method or combination of methods legally available to, and requested by, the Investors, including the registration of the distribution to its shareholders, partners, members or other affiliates. Without limiting the foregoing, subject to any comments from the Commission, each Registration Statement filed pursuant to this Section 2.1.1 shall include a “plan of distribution” approved by Senti Investors holding a majority of the Registrable Securities.

2.1.2 Notification and Distribution of Materials. The Company shall promptly notify the Investors in writing of the effectiveness of the Resale Shelf Registration Statement and shall furnish to them, without charge, such number of copies of the Resale Shelf Registration Statement (including any amendments, supplements and exhibits), the prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other documents as the Investors may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described in the Resale Shelf Registration Statement.

2.1.3 Amendments and Supplements. Subject to the provisions of Section 2.1.1 above, the Company shall promptly prepare and file with the Commission from time to time such amendments and supplements to the Resale Shelf Registration Statement and prospectus used in connection therewith as may be necessary to keep the Resale Shelf Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all the Registrable Securities during the Effectiveness Period (as defined below).

2.1.4 Reduction of Shelf Offering. Notwithstanding the registration obligations set forth in this Section 2.1, in the event the Commission informs the Company (the “Rule 415 Notice”) that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the holders thereof and use its commercially reasonable efforts to file an amendment or amendments to the Resale Shelf Registration Statement as required by the Commission and/or (ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-1, Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with any publicly-available written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”), including, without limitation, Compliance and Disclosure Interpretation 612.09. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will be reduced on a Pro Rata basis, subject to a determination by the Commission that certain Investors must be reduced first based on the number of Registrable Securities held by

A-6

such Investors. In the event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-1, Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Resale Shelf Registration Statement, as amended, or the New Registration Statement. If the Company shall not be able to register for resale all of the Registrable Securities on the Resale Shelf Registration Statement within three (3) months following the date of the Company’s receipt of the Commission’s Notice, then, until such Resale Shelf Registration Statement is effective, each of the Senti Investors shall be entitled to demand registration rights pursuant to Section 2.2 below as long as the demand request is a proposal to sell Registrable Securities with an aggregate market price at the time of request of not less than $5,000,000 (the “Shelf Demand Right”). Shelf Demand Rights shall not be counted as Demand Registrations under Section 2.2.

No Investor shall be named as an “underwriter” in any Registration Statement filed pursuant to this Section 2 without the Investor’s prior written consent; provided that if the Commission requests that an Investor be identified as a statutory underwriter in the Registration Statement, then such Investor will have the option, in its sole and absolute discretion, to either (i) have the opportunity to withdraw from the Registration Statement upon its prompt written request to the Company, in which case the Company’s obligation to register such Investor’s Registrable Securities shall be deemed satisfied or (ii) be included as such in the Registration Statement. Each Registration Statement (and each amendment or supplement thereto, and each request for acceleration of effectiveness thereof) shall be provided to (and shall be subject to the approval, which shall not be unreasonably withheld or delayed, of) the Investors prior to its filing with, or other submission to, the Commission.

2.1.5 Notice of Certain Events. The Company shall promptly notify the Investors in writing of any request by the Commission for any amendment or supplement to, or additional information in connection with, the Resale Shelf Registration Statement required to be prepared and filed hereunder (or prospectus relating thereto). The Company shall promptly notify each Investor, or their representatives, in writing of the filing of the Resale Shelf Registration Statement or any prospectus, amendment or supplement related thereto or any post-effective amendment to the Resale Shelf Registration Statement and the effectiveness of any post-effective amendment.

2.1.6 Underwritten Takedown. If the Company shall receive a request (a “Takedown Demand”) from the (i) holders of Registrable Securities with an estimated market value of at least $5,000,000 or (ii) the holders of Registrable Securities registered under the Resale Shelf Registration Statement that own in the aggregate at least 5% of the outstanding Class A Common Stock requesting a registration of at least $5,000,000 (either an “Initiating Holder”) that the Company effect an Underwritten Takedown of all or any portion of the requesting holder’s Registrable Securities covered under the Resale Shelf Registration Statement, then the Company shall give (x) in connection with any non-marketed underwritten takedown offering (other than a Block Trade), at least two (2) Business Days’ notice of such Takedown Demand to each holder of Registrable Securities (other than the Initiating Holder) that is a participant in the Resale Shelf Registration Statement (“Shelf Participant”), (y) in connection with any Block Trade initiated, notice of such Underwritten Takedown to each holder of Registrable Securities (other than the Initiating Holder) that is a Shelf Participant no later than noon Eastern time on the Business Day prior to the requested Underwritten Takedown and (z) in connection with any marketed Underwritten Takedown, at least five (5) Business Days’ notice of such Underwritten Takedown to each holder of Registrable Securities (other than the Initiating Holder) that is a Shelf Participant. In connection with (x) any non-marketed Underwritten Takedown initiated and (y) any marketed Underwritten Takedown, if any Shelf Participants entitled to receive a notice pursuant to the preceding sentence request inclusion of their Registrable Securities covered by the Resale Shelf Registration Statement (by written notice to the Company, which notice must be received by the Company no later than (A) in the case of a non-marketed Underwritten Takedown (other than a Block Trade), the Business Day following the date notice is given to such participant, (B) in the case of a Block Trade, by 10:00 p.m. Eastern time on the date notice is given to such participant and (C) in the case of a

marketed Underwritten Takedown, three (3) Business Days following the date notice is given to such participant), the Initiating Holder and the other Shelf Participants that request inclusion of their Registrable Securities shall be entitled to sell their Registrable Securities in such offering. Thereupon the Company shall use its commercially reasonable efforts to effect, as expeditiously as possible, the offering in such Underwritten Takedown of:

(i) subject to the restrictions set forth in Section 2.2.4, all Registrable Securities for which the Initiating Holder has requested such offering under Section 2.1.6, and

(ii) subject to the restrictions set forth in Section 2.2.4, all other Registrable Securities that any holders of Registrable Securities covered under the Resale Registration Shelf Statement have requested the Company to offer by request received by the Company in the requisite time period, all to the extent necessary to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be offered.

(a) Promptly after the expiration of the relevant time period, the Company will promptly notify all selling holders of the identities of the other selling holders and the number of shares of Registrable Securities requested to be included therein.

A Registration will not count as a Demand Registration until the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under this Agreement with respect thereto; provided, however, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency or court, the Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter elect to continue the offering; provided, further, that the Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been filed is counted as a Demand Registration or is terminated.

2.2.3 Underwritten Demand Registration. If the Demanding Holders so elect and such holders so advise the Company as part of their written demand for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Demand Registration. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such underwriting by the holders initiating the Demand Registration, and subject to the approval of the Company. The parties agree that, in order to be effected, any Underwritten Demand Registration must result in aggregate proceeds to the selling shareholders of at least $5,000,000.

2.2.4 Reduction of Offering. If the managing Underwriter or Underwriters for a Underwritten Demand Registration that is to be an underwritten offering advises the Company and the Demanding Holders in writing that, in such Underwriter’s or Underwriters’ opinion, the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell, taken together with all other shares of Class A Common Stock or other securities which the Company desires to sell and the shares of Class A Common Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other shareholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of shares, as applicable, the “Maximum Number of Shares”), then the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand Registration has been requested by the Demanding Holders (pro rata in accordance with the number of shares that each such person has requested be included in such registration, regardless of the number of shares held by each such person (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (i), the shares of Class A Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (iii) third, to the extent that the Maximum Number of

A-9

Shares has not been reached under the foregoing clauses (i) and (ii), any shares of Class A Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, as to which “piggy-back” registration has been requested by the holders thereof that can be sold without exceeding the Maximum Number of Shares.

2.2.5 Withdrawal. A Demanding Holder shall have the right to withdraw all or any portion of its Registrable Securities included in an Underwritten Demand Registration pursuant to this Section 2.2 for any reason or no reason whatsoever upon written notice to the Company and the Underwriter or Underwriters of its intention to withdraw from such Underwritten Demand Registration prior to the pricing of such Underwritten Demand Registration; provided, however, that such withdrawn amount shall still be considered an Underwritten Demand Registration. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the registration expenses incurred in connection with an Underwritten Demand Registration prior to its withdrawal under this Section 2.2.5.

2.3 Piggy-Back Registration.

2.3.1 Piggy-Back Rights. If the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for shareholders of the Company for their account (or by the Company and by shareholders of the Company including, without limitation, pursuant to Section 2.2.1), other than a Registration Statement (i) filed in connection with any employee stock option, employee stock purchase, or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing shareholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan, (v) effected pursuant to Section 2.1 or 2.2 (which, for the avoidance of doubt, is addressed in and subject to the rights set forth therein), then the Company shall (x) give written notice of such proposed filing to the holders of Registrable Securities with respect to shares not subject to any lock-up, as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable Securities as such holders may request in writing within five (5) Business Days following receipt of such notice (a “Piggy-Back Registration”). The foregoing rights shall not be available to any Investor at such time as (i) there is an effective Resale Shelf Registration Statement available for the resale of the Registrable Securities pursuant to Section 2.1 (which, for the avoidance of doubt, is addressed in and subject to the rights set forth in, Section 2.1 and 2.2 hereof) and there was no reduction in registered shares as set forth in Section 2.1.4 or (ii) such Registration is solely to be used for the offering of securities by the Company for its own account. The Company shall cause such Registrable Securities to be included in such registration, provided compliance by the Investors with Section 3.4, and the Company shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration.

2.3.2 Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Class A Common Stock which the Company desires to sell, taken together with shares of Class A Common Stock, if any, as to which registration has been demanded pursuant to written contractual arrangements with persons other than the holders of Registrable Securities

A-10

hereunder and the Registrable Securities as to which registration has been requested under this Section 2.3, exceeds the Maximum Number of Shares, then the Company shall include in any such registration:

(a) If the registration is undertaken for the Company’s account: (A) first, the shares of Class A Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Class A Common Stock or other securities, if any, comprised of Registrable Securities, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum Number of Shares, Pro Rata; and (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the shares of Class A Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual piggy-back registration rights with such persons and that can be sold without exceeding the Maximum Number of Shares; and

(b) If the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable Securities or the Company (other than as provided in Section 2.2 which, for the avoidance of doubt, is addressed in and subject to the rights set forth in, Section 2.2 hereof), (A) first, the shares of Class A Common Stock or other securities for the account of the demanding persons that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Class A Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), the shares of Class A Common Stock or other securities, if any, comprised of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A), (B) and (C), the shares of Class A Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Shares.

2.3.3 Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement, if such offering is pursuant to a Demand Registration, or prior to the public announcement of the offering, if such offering is pursuant to an Underwritten Takedown. The Company (whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such Registration Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 3.3.

2.3.4 Unlimited Piggyback Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.3 hereof shall not be counted as a Registration pursuant to a Demand registered effected under Section 2.2 hereof.

3. REGISTRATION PROCEDURES.

3.1 Filings; Information. Whenever the Company is required to effect the registration of any Registrable Securities pursuant to Section 2, the Company shall use its commercially reasonable efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method(s) of distribution thereof as expeditiously as reasonably possible, and in connection with any such request:

3.1.1 Filing Registration Statement. The Company shall use its commercially reasonable efforts to, as expeditiously as possible after receipt of a request for a Demand Registration pursuant to Section 2.1, prepare and file with the Commission a Registration Statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the sale of all

A-11

Registrable Securities to be registered thereunder in accordance with the intended method(s) of distribution thereof, and shall use its commercially reasonable efforts to cause such Registration Statement to become effective and use its commercially reasonable efforts to keep it effective for the Effectiveness Period (as defined below); provided, however, that the Company shall have the right to defer any Demand Registration for up to forty-five (45) days, and any Piggy-Back Registration for such period as may be applicable to deferment of any Demand Registration to which such Piggy-Back Registration relates, in each case if the Company shall furnish to the holders a certificate signed by the Company stating that, in the good faith judgment of the Board of Directors of the Company (the “Company Board”), it would require the Company to make an Adverse Disclosure; provided, further, however, that the Company shall not have the right to exercise the right set forth in the immediately preceding proviso twice, or for more than sixty (60) total calendar days in any 360-day period.

3.1.2 Copies. The Company shall, prior to filing a Registration Statement or prospectus, or any amendment or supplement thereto, furnish without charge to the holders of Registrable Securities included in such registration, and such holders’ legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case, including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such Registration Statement (including each preliminary prospectus), and such other documents as the holders of Registrable Securities included in such registration or legal counsel for any such holders may request in order to facilitate the disposition of the Registrable Securities owned by such holders.

3.1.3 Amendments and Supplements. The Company shall prepare and file with the Commission such amendments, including post-effective amendments, and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and in compliance with the provisions of the Securities Act until the date on which all Registrable Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration Statement or such securities have been withdrawn (the “Effectiveness Period”).

3.1.4 Notification. After the filing of a Registration Statement, the Company shall promptly, and in no event more than two (2) Business Days after such filing, notify the holders of Registrable Securities included in such Registration Statement of such filing, and shall further notify such holders promptly and confirm such advice in writing in all events within two (2) Business Days of the occurrence of any of the following: (i) when such Registration Statement becomes effective; (ii) when any post-effective amendment to such Registration Statement becomes effective; (iii) the issuance or threatened issuance by the Commission of any stop order (and the Company shall take all actions required to prevent the entry of such stop order or to remove it if entered); and (iv) any request by the Commission for any amendment or supplement to such Registration Statement or any prospectus relating thereto or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and promptly make available to the holders of Registrable Securities included in such Registration Statement any such supplement or amendment; except that before filing with the Commission a Registration Statement or prospectus or any amendment or supplement thereto, including documents incorporated by reference, the Company shall furnish to the holders of Registrable Securities included in such Registration Statement and to the legal counsel for any such holders, copies of all such documents proposed to be filed sufficiently in advance of filing to provide such holders and legal counsel with a reasonable opportunity to review such documents and comment thereon.

3.1.5 Securities Laws Compliance. The Company shall use its commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may reasonably request and (ii) take such

A-12

action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph or subject itself to taxation in any such jurisdiction.

The Company shall enter into customary agreements (including, if applicable, an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities. The representations, warranties and covenants of the Company in any underwriting agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall also be made to and for the benefit of the holders of Registrable Securities included in such registration statement, and the representations, warranties and covenants of the holders of Registrable Securities included in such registration statement in any underwriting agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall also be made to and for the benefit of the Company.

In the event of an Underwritten Takedown or an Underwritten Demand Registration, the Company shall obtain a “cold comfort” letter from the Company’s independent registered public accountants in the event of an underwritten offering, and a customary “bring-down” thereof, in customary form and covering such matters of the type customarily covered by “cold comfort” letters, as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating holders. For the avoidance of doubt, this Section 3.1.7 shall not apply to any Block Trade.

3.1.8 Opinions and Negative Assurance Letters. In the event of an Underwritten Takedown or an Underwritten Demand Registration, on the date the Registrable Securities are delivered for sale pursuant to any Registration, the Company shall obtain an opinion and negative assurances letter, each dated such date, of one (1) counsel representing the Company for the purposes of such Registration, including an opinion of local counsel if applicable, addressed to the holders, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to such Registration in respect of which such opinion is being given as the holders, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions, and reasonably satisfactory to a majority in interest of the participating holders. For the avoidance of doubt, this Section 3.1.8 shall not apply to any Block Trade.

3.1.11 Records. Upon execution of confidentiality agreements, the Company shall make available for inspection by the holders of Registrable Securities included in such Registration Statement, any Underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other professional retained by any holder of Registrable Securities included in such Registration Statement or any Underwriter, all financial and other records, pertinent corporate documents and properties of the Company, as shall be necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information requested by any of them in connection with such Registration Statement.

A-13

3.1.12 Earnings Statement. The Company shall comply with all applicable rules and regulations of the Commission and the Securities Act, and make available to its shareholders, as soon as practicable, an earnings statement covering a period of twelve (12) months, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

3.1.13 Road Show. If an offering pursuant to this Agreement is conducted as an Underwritten Takedown or Underwritten Demand Registration and involves Registrable Securities with an aggregate offering price (before deduction of underwriting discounts) is expected to exceed $10,000,000, the Company shall use its reasonable best efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such offering.

3.1.14 Listing. The Company shall use its commercially reasonable efforts to cause all Registrable Securities included in any Registration Statement to be listed on such exchanges or otherwise designated for trading in the same manner as similar securities issued by the Company are then listed or designated.

3.2 Obligation to Suspend Distribution. Upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.1.4(iv), or, upon any suspension by the Company, pursuant to a good faith reasonable determination of the board of directors of the Company that the offer or sale of Registrable Securities would require the Company to disclose Adverse Disclosure, each holder of Registrable Securities included in any registration shall immediately discontinue disposition of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such holder receives the supplemented or amended prospectus contemplated by Section 3.1.4(iv) or the restriction on the ability of “insiders” to transact in the Company’s securities is removed, as applicable, and, if so directed by the Company, each such holder will deliver to the Company or destroy all copies, other than permanent file copies then in such holder’s possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice. The foregoing right to delay or suspend may be exercised by the Company for no longer than sixty (60) days in any consecutive 12-month period.

3.4 Information. The holders of Registrable Securities shall promptly provide such information as may reasonably be requested by the Company, or the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any Registrable Securities under the Securities Act and in connection with the Company’s obligation to comply with Federal and applicable state securities laws.

A-14

3.5 Other Obligations.

3.5.1 At any time and from time to time after the expiration of any lock-up to which such shares are subject, if any, in connection with a sale or transfer of Registrable Securities exempt from registration under the Securities Act or through any broker-dealer transactions described in the plan of distribution set forth within any prospectus and pursuant to the Registration Statement of which such prospectus forms a part, the Company shall, subject to the receipt of customary documentation required from the applicable holders in connection therewith, (i) promptly instruct its transfer agent to remove any restrictive legends applicable to the Registrable Securities being sold or transferred and (ii) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under subclause (i). In addition, the Company shall cooperate reasonably with, and take such customary actions as may reasonably be requested by such holders in connection with the aforementioned sales or transfers.

3.5.2 The stock certificates evidencing the Registrable Securities (and/or book entries representing the Registrable Securities) held by each Investor shall not contain or be subject to any legend restricting the transfer thereof (and the Registrable Securities shall not be subject to any stop transfer or similar instructions or notations): (A) while a Registration Statement covering the sale or resale of such securities is effective under the Securities Act, or (B) if such Investor provides customary paperwork to the effect that it has sold such shares pursuant to Rule 144, or (C) if such Registrable Securities are eligible for sale under Rule 144(b)(1) as set forth in customary non-affiliate paperwork provided by such Investor, or (D) if at any time on or after the date that is one year after the Form 10 Disclosure Filing Date such Investor certifies that it is not an affiliate of the Company and that such Investor’s holding period for purposes of Rule 144 in respect of such Registrable Securities is at least six (6) months, or (E) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) as determined in good faith by counsel to the Company or set forth in a legal opinion delivered by nationally recognized counsel to the Investor (collectively, the “Unrestricted Conditions”). The Company agrees that following the date that the Resale Shelf Registration Statement has been declared effective by the Commission or at such time as any of the Unrestricted Conditions is met or such legend is otherwise no longer required it will, no later than two (2) Business Days following the delivery by an Investor to the Company or its transfer agent of a certificate representing any Registrable Securities, issued with a restrictive legend, (or, in the case of Registrable Securities represented by book entries, delivery by an Investor to the Company or its transfer agent of a legend removal request) deliver or cause to be delivered to such Investor a certificate or, at the request of such Investor, deliver or cause to be delivered such Registrable Securities to such Investor by crediting the account of such Investor’s prime broker with DTC through its Deposit/Withdrawal at Custodian (DWAC) system, in each case, free from all restrictive and other legends and stop transfer or similar instructions or notations. If any of the Unrestricted Conditions is met at the time of issuance of any Registrable Securities (e.g., upon exercise of warrants), then such securities shall be issued free of all legends. Each Investor shall have the right to pursue any remedies available to it hereunder, or otherwise at law or in equity, including a decree of specific performance and/or injunctive relief, with respect to the Company’s failure to timely deliver shares of Class A Common Stock without legend as required pursuant to the terms hereof.

3.5.3 As long as Registrable Securities remain outstanding the Company shall (a) cause the Class A Common Stock to be eligible for clearing through DTC, through its DWAC system; (b) be eligible and participating in the Direct Registration System (DRS) of DTC with respect to the Class A Common Stock; (c) ensure that the transfer agent for the Class A Common Stock is a participant in, and that the Class A Common Stock is eligible for transfer pursuant to, DTC’s Fast Automated Securities Transfer Program (or successor thereto); and (d) use its reasonable best efforts to cause the Class A Common Stock to not at any time be subject to any DTC “chill,” “freeze” or similar restriction with respect to any DTC services, including the clearing of shares of Common Stock through DTC, and, in the event the Class A Common Stock becomes subject to any DTC “chill,” “freeze” or similar restriction with respect to any DTC services, use its reasonable best efforts to cause any such “chill,” “freeze” or similar restriction to be removed at the earliest possible time.

4. INDEMNIFICATION AND CONTRIBUTION.

4.1 Indemnification by the Company. The Company agrees to indemnify and hold harmless, to the fullest extent permitted by law, each Investor and each other holder of Registrable Securities, and each of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any, who controls an Investor and each other holder of Registrable Securities (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether joint or several, (including reasonable and documented costs of investigation and legal expenses and any indemnity and contribution payments made to underwriters) arising out of or based upon any untrue statement (or allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission (or alleged omission) to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss, claim, damage or liability is finally judicially determined to have arisen out of or resulted from any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein or to the extent related to any selling holder’s violation of the federal securities laws (including Regulation M) or failure to sell the Registrable Securities in accordance with the plan of distribution contained in the prospectus.

4.2 Indemnification by Holders of Registrable Securities. Each selling holder of Registrable Securities will, in the event that any Registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and hold harmless to the fullest extent permitted by law the Company, each of its directors and officers, and each other selling holder of Registrable Securities and each other person, if any, who controls such other selling holder within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, only insofar as such losses, claims, judgments, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made expressly in reliance upon and in conformity with information furnished in writing to the Company by such selling holder in writing expressly for use therein, or (ii) such selling holder’s failure to sell the Registrable Securities in accordance with the plan of distribution contained in the prospectus, and shall reimburse the Company, its directors and officers, and each other selling holder or controlling person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling holder upon the sale of Registrable Securities giving rise to such indemnification obligations.

4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage or liability or any action in respect of which indemnity may be sought pursuant to Sections 4.1 or 4.2, such person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other

A-16

person for indemnification hereunder, notify such other person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel, which counsel is reasonably acceptable to the Indemnifying Party) to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

4.4 Contribution.

4.4.1 If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any loss, claim, damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

4.4.2 The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in Section 4.4.1.

4.4.3 The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such holder from the sale of Registrable Securities which gave rise to such contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

5. UNDERWRITING AND DISTRIBUTION.

5.1 Rule 144. The Company covenants that it shall timely file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as the holders of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holders to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission. Upon reasonable prior written request, the Company shall deliver to the Investors a customary written statement as to whether it has complied with such requirements.

6. LOCK-UP AGREEMENTS.

6.1 Investor Lock-Up. Without limiting the terms of any other Ancillary Document or any other contract, agreement or understanding entered into by any Investor, each Investor agrees that it shall not Transfer any shares of Class A Common Stock or any securities convertible into or exercisable or exchangeable (directly or indirectly) for shares of Class A Common Stock (including New Securities) until the Lock-Up Release Date; provided, however, that the foregoing restrictions shall (i) not apply to any shares of Class A Common Stock purchased by an Investor in the PIPE Financing and (ii) with respect to the Non-Redemption Investors, only apply to shares of Class A Common Stock received by the Non-Redemption Investors pursuant to the Non-Redemption Agreements. The foregoing restriction is expressly agreed to preclude each Investor from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of such Investor’s shares of Class A Common Stock even if such shares of Class A Common Stock would be disposed of by someone other than the undersigned until the Lock-Up Release Date. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including, without limitation, any put or call option) with respect to any of the Investor’s shares of Class A Common Stock or with respect to any security that includes, relates to, or derives any significant part of its value from such shares of Class A Common Stock. The foregoing restrictions shall not apply to Transfers made: (i) pursuant to a bona fide gift or charitable contribution; (ii) by will or intestate succession upon the death of an Investor; (iii) to any Permitted Transferee; (iv) pursuant to a court order or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union; or (v) in the case of any Investor that is not a natural person, pro rata to the direct or indirect partners, members or shareholders of an Investor or any related investment funds or vehicles controlled or managed by such persons or their respective affiliates in connection with the liquidation or dissolution thereof; or (vi) in the event of the Company’s completion of a liquidation, merger, share exchange or other similar transaction which results in all of its shareholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property; provided that in the case of (i) through (vi), the recipient of such Transfer must enter into a written agreement agreeing to be bound by the terms of this Agreement in form and substance reasonably satisfactory to the Company, including the transfer restrictions set forth in this Section 6.1.

The foregoing notwithstanding, to the extent any Investor is granted a release or waiver from the restrictions contained in this Section 6 prior to the expiration of the Lock-Up Release Date, then all Investors shall be automatically granted a release or waiver from the restrictions contained in this Section 6 to the same extent, on substantially the same terms as and on a pro rata basis with, the Investor to which such release or waiver is granted.

7. RESERVED.

8. MISCELLANEOUS.

8.1 Other Registration Rights and Arrangements. The Company represents and warrants that no person, other than a holder of the Registrable Securities and the investors of the PIPE Financing has any right to require the Company to register any of the Company’s capital stock for sale or to include the Company’s capital stock in any registration filed by the Company for the sale of capital stock for its own account or for the account of any

A-18

other person. The parties hereby terminate the Prior Agreements, each of which shall be of no further force and effect and is hereby superseded and replaced in its entirety by this Agreement. The Company shall not hereafter enter into any agreement with respect to its securities which is inconsistent with or violates the rights granted to the holders of Registrable Securities in this Agreement and in the event of any conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

8.2 Assignment; No Third-Party Beneficiaries. This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part. This Agreement and the rights, duties and obligations of the holders of Registrable Securities hereunder may be freely assigned or delegated by such holder of Registrable Securities in conjunction with and to the extent of any permitted transfer of Registrable Securities by any such holder to a Permitted Transferee. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties hereto and their respective successors and assigns and the holders of Registrable Securities and their respective successors and permitted assigns. This Agreement is not intended to confer any rights or benefits on any persons that are not party hereto other than as expressly set forth in Section 4 and this Section 8.2. The rights of a holder of Registrable Securities under this Agreement may be transferred by such a holder to a transferee who acquires or holds Registrable Securities; provided, however, that such transferee has executed and delivered to the Company a properly completed agreement to be bound by the terms of this Agreement substantially in form attached hereto as Exhibit A (an “Addendum Agreement”), and the transferor shall have delivered to the Company no later than fifteen (15) days following the date of the transfer, written notification of such transfer setting forth the name of the transferor, the name and address of the transferee, and the number of Registrable Securities so transferred. The execution of an Addendum Agreement shall constitute a permitted amendment of this Agreement.

8.3 Amendments and Modifications. Upon the written consent of the Company and the Investors of at least a majority in interest of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects an Investor, solely in his, her or its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from other Investors (in such capacity) shall require the consent of such Investor so affected; provided, further, however, that any waiver, amendment or repeal of the restrictions set forth in Section 6.1 (or of this Section 8.3 in respect of this proviso) shall require the prior written consent of the Sponsor. No course of dealing between any Investor or the Company and any other party hereto or any failure or delay on the part of an Investor or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Investor or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

8.4 Term. This Agreement shall terminate upon the earlier of (i) the tenth anniversary of the date of this Agreement or (ii) the date as of which there shall be no Registrable Securities outstanding; provided further that with respect to any Investor, such Investor will have no rights under this Agreement and all obligations of the Company to such Investor under this Agreement shall terminate upon the earlier of (x) the date at least one year after the date hereof that such Investor ceases to hold at least 1 % of the Registrable Securities outstanding on the date hereof or (y) if such Investor is a director or an executive officer of the Company, the date such Investor no longer serves as a director or an executive officer of the Company; provided, however, that such termination as to an Investors shall not apply to the following provisions until such Investor no longer holds any Registrable Securities: Sections 3.1.4, 3.1.5, 3.1.10, 3.1.12, 3.1.14, 3.2, 3.3, 3.4, 3.5, 7.3, 8.3, 8.5 and Articles IV and V. Notwithstanding the foregoing, the piggy-back registration rights provided for in Section 2.3 of this Agreement shall terminate no later than the third anniversary of the date of this Agreement.

8.5 Notices. All notices, demands, requests, consents, approvals or other communications (collectively, “Notices”) required or permitted to be given hereunder or which are given with respect to this Agreement shall be in writing and shall be personally served, delivered by reputable air courier service with charges prepaid, or

EXECUTION VERSION

SPONSOR SUPPORT AGREEMENT

This SPONSOR SUPPORT AGREEMENT (this “Agreement”), dated as of December 19, 2021, is made by and among Dynamics Sponsor LLC, a Delaware limited liability company (the “Sponsor”) as the sole holder of Class B common stock par value $0.0001 per share (the “Class B Common Stock”) of Dynamics Special Purpose Corp., solely for purposes of Section 5 of this Agreement, the other Persons party hereto as “Other DYNS Insiders” set forth on the signature pages hereto (the “Other DYNS Insiders”, and together with the Sponsor, collectively, the “DYNS Insiders”), Dynamics Special Purpose Corp., a Delaware corporation (“DYNS”), and Senti Biosciences, Inc., a Delaware corporation (the “Company”). The Sponsor, DYNS and the Company shall be referred to herein from time to time collectively as the “Parties”. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Business Combination Agreement (as defined below).

WHEREAS, DYNS, the Company and Explore Merger Sub, Inc., a Delaware corporation (“Merger Sub”), entered into that certain Business Combination Agreement, dated as of the date hereof (as it may be amended, restated or otherwise modified from time to time in accordance with its terms, the “Business Combination Agreement”);

WHEREAS, as of the date of this Agreement, the Sponsor owns 5,750,000 shares of Class B Common Stock; and

WHEREAS, the Business Combination Agreement contemplates that the Parties will enter into this Agreement concurrently with the entry into the Business Combination Agreement by the parties thereto, pursuant to which, among other things, the Sponsor will vote in favor of approval of the Business Combination Agreement and the transactions contemplated thereby (including the Merger).

NOW, THEREFORE, in consideration of the premises and the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as follows:

1. Agreement to Vote.

(a) Pursuant to Section 3 of that certain Letter Agreement, dated as of May 25, 2021 (the “Insider Letter”), by and among DYNS and the DYNS Insiders, the Sponsor hereby consents to the entry by DYNS into the Business Combination Agreement and each other Ancillary Document to which DYNS is or will be a party.

(b) For so long as this Agreement is in effect, the Sponsor hereby agrees to vote at any meeting of the stockholders of DYNS, and in any action by written resolution of the stockholders of DYNS, all of the Sponsor’s shares of Class B Common Stock (together with any other Equity Securities of DYNS that the Sponsor holds of record or beneficially, as of the date of this Agreement, or of which the Sponsor acquires record or beneficial ownership after the date hereof, collectively, the “Subject DYNS Equity Securities”) in favor of the Required Transaction Proposals, and against any proposal that conflicts or materially impedes or interferes with any Required Transaction Proposals, including any DYNS Acquisition Proposal, or that would adversely affect or delay the consummation of the transactions contemplated by the Business Combination Agreement. The Sponsor shall validly execute and deliver to DYNS, on (or effective as of) the fifth (5th) Business Day following the date that the Proxy Statement/Prospectus is disseminated by DYNS to DYNS’s stockholders (following the date that the Registration Statement/Proxy Statement becomes effective), a properly completed voting proxy in the form distributed by or on behalf of DYNS in favor of the Required Transaction Proposals. In the event of any

B-1

equity dividend or distribution, or any change in the equity interests of DYNS by reason of any equity dividend or distribution, equity split, recapitalization, combination, conversion, exchange of equity interests or the like prior to the Closing, the term “Subject DYNS Equity Securities” shall be deemed to refer to and include the Subject DYNS Equity Securities as well as all such equity dividends and distributions and any securities into which or for which any or all of the Subject DYNS Equity Securities may be changed or exchanged or which are received in such transaction.

2. Waivers.

(a) The Sponsor hereby waives, subject to, and conditioned upon, the occurrence of the Closing (for himself, herself or itself and for his, her or its, successors, heirs and assigns), to the fullest extent permitted by law and the Governing Documents of DYNS, and agrees not to assert or perfect, any rights to adjustment or other anti-dilution protections with respect to the rate that the shares of Class B Common Stock held by the Sponsor convert into shares of Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement. For the avoidance of doubt, the foregoing waiver does not waive the Sponsor’s rights under Section 4.3(b) of DYNS’s Amended and Restated Certificate of Incorporation, which provides that in no event may any Class B Common Stock convert into shares of Class A Common Stock at a ratio that is less than one-for-one.

(b) The Sponsor hereby waives any and all Redemption Rights in respect to the Required Transaction Proposals, and shall not elect to cause DYNS to redeem any Subject DYNS Equity Securities beneficially owned or owned of record by the Sponsor in connection with the Required Transaction Proposals.

(c) The Sponsor hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account with respect to the Subject DYNS Equity Securities.

3. Transfer of Shares.

(a) From the date hereof until the earlier of (i) the Closing or (ii) the valid termination of this Agreement pursuant to Section 6, the Sponsor hereby agrees that the Sponsor shall not, directly or indirectly, (i) sell, assign, transfer (including by operation of law), place a lien on, pledge, dispose of or otherwise encumber any of his, her or its Subject DYNS Equity Securities or otherwise agree to do any of the foregoing (each, a “Transfer”), (ii) deposit any of the Sponsor’s Subject DYNS Equity Securities into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect to any of the Sponsor’s Subject DYNS Equity Securities that conflicts with any of the covenants or agreements set forth in this Agreement, (iii) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer (including by operation of law) or other disposition of any of the Sponsor’s Subject DYNS Equity Securities, (iv) engage in any hedging or other transaction which is designed to, or which would (either alone or in connection with one or more events or developments (including the satisfaction or waiver of any conditions precedent)), result in a sale or disposition of the Sponsor’s Subject DYNS Equity Securities or (v) take any action that would have the effect of preventing or materially delaying the performance of the Sponsor’s obligations hereunder , except (A) as affirmatively permitted by the Business Combination Agreement or (B) any Transfer that would be permitted pursuant to Section 5(c) of the Insider Letter.

(b) From the Closing until the earlier of (i) the Lock-Up Release Date or (ii) the valid termination of this Agreement pursuant to Section 6, the Sponsor hereby agrees that the Sponsor shall not, directly or indirectly, Transfer any of the Sponsor’s Subject DYNS Equity Securities; provided, however, that the foregoing shall not apply to any Transfer (A) to DYNS’s officers or directors, any affiliates or family member of any of DYNS’s officers or directors, any members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (B) in the case of an individual, by gift to a member of one of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (C) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (D) in the case of an individual, pursuant to a

B-2

qualified domestic relations order; (E) by private sales or transfers made in connection with the transactions contemplated by the Business Combination Agreement; and (F) by virtue of the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; provided, that any transferee of any Transfer of the type set forth in clauses (A) through (F) must enter into a written agreement in form and substance reasonably satisfactory to the Company agreeing to be bound by this Agreement prior to the occurrence of such Transfer. For purposes of this Agreement, the “Lock-Up Release Date” means the earliest of (A) the one year anniversary of the Closing and (B) subsequent to the Closing, (x) if the last reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 consecutive trading day period commencing at least 150 days after the Closing, or (y) the date upon completion of a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the public stockholders of DYNS having the right to exchange their DYNS Common Stock for cash, securities or other property.

(c) In furtherance of the foregoing, DYNS hereby agrees to (i) place a revocable stop order on all Subject DYNS Equity Securities subject to Section 3(a) and Section 3(b), including those which may be covered by a registration statement, and (ii) notify DYNS’s transfer agent in writing of such stop order and the restrictions on such Subject DYNS Equity Securities under Section 3(a) and Section 3(b) and direct DYNS’s transfer agent not to process any attempts by the Sponsor to Transfer any Subject DYNS Equity Securities except in compliance with Section 3(a) or Section 3(b); for the avoidance of doubt, the obligations of DYNS under this Section 3(c) shall be deemed to be satisfied by the existence of any similar stop order and restrictions currently existing on the Subject DYNS Equity Securities.

4. Other Covenants. The Sponsor hereby agrees to be bound by and subject to (i) Sections 5.3(a) (Confidentiality and Access to Information) and 5.4(a) (Public Announcements) of the Business Combination Agreement to the same extent as such provisions apply to the parties to the Business Combination Agreement, as if the Sponsor is directly a party thereto, and (ii) Section 5.6(c) (Exclusive Dealing) of the Business Combination Agreement to the same extent as such provisions apply to DYNS as if the Sponsor is directly party thereto.

5. Termination of DYNS Class B Common Stock Lock-up Period. Each DYNS Insider and DYNS hereby agree that effective as of the consummation of the Closing (and not before), Section 5 of the Insider Letter shall be amended and restated in its entirety as follows:

“5. Reserved.”

The amendment and restatement of the Insider Letter set forth in this Section 5 shall be void and of no force and effect if the Business Combination Agreement shall be terminated for any reason in accordance with its terms.

6. Termination. This Agreement shall automatically terminate, without any notice or other action by any Party, and be void ab initio upon the earlier of (a) the Effective Time; and (b) the termination of the Business Combination Agreement in accordance with its terms. Upon termination of this Agreement as provided in the immediately preceding sentence, none of the Parties shall have any further obligations or Liabilities under, or with respect to, this Agreement. Notwithstanding the foregoing or anything to the contrary in this Agreement, (i) the termination of this Agreement pursuant to Section 6(b) shall not affect any Liability on the part of any Party for a Willful Breach of any covenant or agreement set forth in this Agreement prior to such termination or Fraud, (ii) Sections 2, 5 and 10 (solely to the extent related to the foregoing Sections 2 or 5) shall each survive the termination of this Agreement pursuant to Section 6(a), and (iii) Sections 7, 8, 9 and 10 (solely to the extent related to the following Sections 7 or 9) shall survive any termination of this Agreement. For purposes of this Section 6, (x) “Willful Breach” means an intentional and willful breach, or an intentional and willful failure to perform, in each case that is the consequence of an act or omission by a Party with the knowledge that the taking of such act or failure to take such act would cause a breach of this Agreement and (y) “Fraud” means an act or omission by a Party consisting of a false or incorrect representation or warranty expressly set forth in this Agreement with the intent that another Party rely on such representations and warranties, coupled with such other

B-3

Party’s detrimental reliance on such representations and warranties under circumstances that constitute common law fraud under the Laws of the State of New York. For the avoidance of doubt, “Fraud” does not include any claim for equitable fraud, promissory fraud, unfair dealings fraud, or any torts based on negligence or recklessness.

7. No Recourse. Except for claims pursuant to the Business Combination Agreement or any other Ancillary Document by any party(ies) thereto against any other party(ies) thereto, each Party agrees that (a) this Agreement may only be enforced against, and any action for breach of this Agreement may only be made against, the Parties, and no claims of any nature whatsoever (whether in tort, contract or otherwise) arising under or relating to this Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby shall be asserted against any non-party affiliate of the Company or DYNS, as applicable (other than the DYNS Insiders named as parties hereto, on the terms and subject to the conditions set forth herein), and (b) none of the Company’s non-party affiliates or DYNS’s non-party affiliates (other than the DYNS Insiders named as parties hereto, on the terms and subject to the conditions set forth herein) shall have any Liability arising out of or relating to this Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby, including with respect to any claim (whether in tort, contract or otherwise) for breach of this Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished in connection with this Agreement, the negotiation hereof or the transactions contemplated hereby.

8. Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary, (a) the Sponsor makes no agreement or understanding herein in any capacity other than in the Sponsor’s capacity as a record holder and beneficial owner of the Subject DYNS Equity Securities, and not in the Sponsor’s (or any of its representatives’) capacity as a director, officer or employee of any DYNS Party, and (b) nothing herein will be construed to limit or affect any action or inaction by the Sponsor or any representative of the Sponsor serving as a member of the board of directors (or other similar governing body) of any DYNS Party or as an officer, employee or fiduciary of any DYNS Party, in each case, acting in such person’s capacity as a director, officer, employee or fiduciary of such DYNS Party.

9. No Third Party Beneficiaries. This Agreement shall be for the sole benefit of the Parties and their respective successors and permitted assigns and is not intended, nor shall be construed, to give any Person, other than the Parties and their respective successors and assigns, any legal or equitable right, benefit or remedy of any nature whatsoever in connection with the matters governed by this Agreement. Nothing in this Agreement, expressed or implied, is intended to or shall constitute the Parties, partners or participants in a joint venture.

10. Incorporation by Reference. Sections 8.1 (Non-Survival), 8.2 (Entire Agreement; Assignment), 8.3 (Amendment), 8.4 (Notices), 8.5 (Governing Law), 8.7 (Construction; Interpretation), 8.10 (Severability), 8.11 (Counterparts; Electronic Signatures), 8.15 (Waiver of Jury Trial), 8.16 (Submission to Jurisdiction) and 8.17 (Remedies) of the Business Combination Agreement are incorporated herein and shall apply to this Agreement mutatis mutandis.

NOW, THEREFORE, in consideration of the foregoing recitals, the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, Parent and the Holders agree as follows:

Section 1. Agreement to Vote Shares.

(a) Each Holder, solely in their capacity as a stockholder of the Company, agrees that, unless the Expiration Date has occurred, it shall validly execute and deliver to the Company, within forty eight (48) hours after the date that the Proxy Statement/Prospectus is disseminated by the Company to the Company’s stockholders following the date that the Registration Statement becomes effective, a written consent approving the Business Combination Agreement, the Merger, and any other matters necessary or reasonably requested by the Company for consummation of the Merger and the other transactions contemplated by the Business Combination Agreement in respect of the Shares. In addition, unless the Expiration Date has occurred, each Holder irrevocably and unconditionally agrees that at any meeting of the holders of Company Shares, or any

C-1

adjournment or postponement thereof, or in connection with any written consent of the holders of Company Shares, with respect to the Business Combination Agreement or any of the transactions contemplated thereby, including the Merger, such Holder shall:

(i) appear at any such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(ii) vote (or cause to be voted) (i) in favor of adoption and approval of the Business Combination Agreement, the Merger, and any other matters necessary or reasonably requested by the Company for consummation of the Merger and the other transactions contemplated by the Business Combination Agreement, and (ii) against any proposal that would constitute a breach thereof or that conflicts or materially impedes or interferes therewith, including any Company Acquisition Proposal, or would adversely affect or delay the consummation of the transactions contemplated by the Business Combination Agreement.

(b) Without limiting any other rights or remedies of Parent, each Holder hereby irrevocably appoints Parent or any individual designated by Parent as such Holder’s agent, attorney-in-fact and proxy (with full power of substitution and resubstituting), for and in the name, place and stead of such Holder, up to the Expiration Date, to attend on behalf of such Holder any meeting of the Company Stockholders with respect to the matters described in Section 1(a)(ii), to include the Shares held by such Holder in any computation for purposes of establishing a quorum at any such meeting of the Company Stockholders, to vote (or cause to be voted) such Shares or consent (or withhold consent) with respect to any of the matters described in Section 1(a)(ii) in connection with any meeting of the Company Stockholders or any action by written consent by the Company Stockholders (including the Company Stockholder Written Consent), in each case, only in the event and to the extent that the Holder fails to timely perform or otherwise comply with the covenants, agreements or obligations set forth in Section 1(a). The proxyholder may not exercise the proxy granted pursuant to this Section 1(b) on any matter except those provided in Section 1(a), and each Holder may vote its, his or her Shares on all other matters, subject to the other applicable covenants, agreements and obligations set forth in this Agreement.

(c) The proxy granted by each Holder pursuant to Section 1(b) (i) will be automatically revoked upon the Expiration Date, (ii) is coupled with an interest sufficient in law to support, subject to clause (i), an irrevocable proxy and is granted in consideration for Parent entering into the Business Combination Agreement and agreeing to consummate the transactions contemplated thereby, and (iii) is a durable proxy and shall survive the bankruptcy, dissolution, death, incapacity or other inability to act by such Holder and shall revoke any and all prior proxies granted by such Holder with respect to the Shares held by such Holder. The vote or consent of the proxyholder in accordance with Section 1(b) and with respect to the matters in Section 1(a)(ii) shall control in the event of any conflict between such vote or consent by such proxyholder and a vote or consent by each Holder (or any other Person with the power to vote the Shares held by such Holder) with respect to the matters in Section 1(a)(ii).

(d) Prior to the Expiration Date, except as expressly set forth herein, no Holder shall enter into any agreement, understanding or arrangement (whether written or oral) with any Person to vote or give instructions in any manner inconsistent with this Section 1. Any such vote shall be cast, or consent shall be given, in accordance with such procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent.

(e) In the event of any equity dividend or distribution, or any change in the equity interests of the Company by reason of any equity dividend or distribution, equity split, recapitalization, combination, conversion, exchange of equity interests or the like prior to the Closing (including the transactions contemplated by the Business Combination Agreement), the term “Shares” shall be deemed to refer to and include the Shares as well as all such equity dividends and distributions and any securities into which or for which any or all of the Shares may be changed or exchanged or which are received in such transaction (including the DYNS Common Stock received as result of the consummation of the Merger pursuant to the Business Combination Agreement). For the

C-2

avoidance of doubt, in no event shall the term “Shares” be deemed to refer to or include any securities issued to any Holder pursuant to any Subscription Agreement.

Section 2. Transfer of Shares.

(a) Each Holder agrees that, prior to the Expiration Date, he, she or it shall not sell, assign, transfer (including by operation of law), place a lien on, pledge, dispose of or otherwise encumber any of his, her or its Shares or otherwise agree to do any of the foregoing (collectively, a “Transfer”), except (a) in compliance with all applicable federal and state securities Laws, (b) in compliance with the Governing Documents of the Company (it being understood and agreed than any waiver or consent to any Transfer pursuant to the Governing Documents of the Company shall require the mutual consent of Parent and the Company), (c) in compliance with the Business Combination Agreement and (d) if, prior to such Transfer, each transferee signs a counterpart to this Agreement pursuant to which such transferee agrees to be bound by the terms of this Agreement and to be a “Holder” hereunder; provided that, any subsequent transfer of the Shares by any such transferee shall also be made pursuant to, and in accordance with, all of the provisions of this Section 2 to the same extent as if each such transferee were a Holder. Each Holder shall not, directly or indirectly,

(i) pledge, encumber or create a Lien on any Shares or enter into any contract, option, commitment or other arrangement or understanding with respect to the foregoing;

(ii) grant any proxies or powers of attorney or enter into a voting agreement or other arrangement with respect to any of such Holder’s Shares;

(iii) enter into, or deposit any of such Holder’s Shares into, a voting trust or take any other action which would, or would reasonably be expected to, result in a diminution of the voting power represented by any of such Holder’s Shares; or

(iv) commit or agree to take any of the foregoing actions.

As used in this Agreement, the term “Expiration Date” shall mean the earliest to occur of (i) the Effective Time, (ii) such date and time as the Business Combination Agreement shall be terminated pursuant to Article 7 thereof and (iii) upon mutual written agreement of the Parties.

(b) From the Effective Time until the earlier of (i) the Lock-Up Release Date or (ii) the valid termination of this Agreement pursuant to Section 13, each Holder hereby agrees that it shall not, directly or indirectly, Transfer any of the Shares (including, for the avoidance of doubt, the DYNS Common Stock received as result of the consummation of the Merger pursuant to the Business Combination Agreement); provided, however, that the foregoing shall not apply to any Transfer (A) to such Holder’s officers or directors, any affiliates or family member thereof or any of their affiliates; (B) in the case of an individual, by gift to a member of one of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (C) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (D) in the case of an individual, pursuant to a qualified domestic relations order; (E) by private sales or transfers made in connection with the transactions contemplated by the Business Combination Agreement; (F) pro rata to the direct or indirect partners, members or shareholders of such Holder or any related investment funds or vehicles controlled or managed by such persons or their respective affiliates in connection with the liquidation or dissolution thereof, and (G) by virtue of such Holder’s organizational documents upon liquidation or dissolution thereof; provided, that any transferee of any Transfer of the type set forth in clauses (A) through (G) must enter into a written agreement in form and substance reasonably satisfactory to Parent agreeing to be bound by this Agreement prior to the occurrence of such Transfer. For purposes of this Agreement, the “Lock-Up Release Date” means the earliest of (A) the one year anniversary of the Closing and (B) subsequent to the Closing, (x) if the last reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 consecutive trading day period commencing at least 150 days after the Closing, or (y) the date upon completion of a liquidation, merger,

C-3

stock exchange, reorganization or other similar transaction that results in all of the public stockholders of Parent having the right to exchange their DYNS Common Stock for cash, securities or other property. In furtherance of the foregoing, Parent hereby agrees to (i) place a revocable stop order on all Shares subject to Section 2(b), including those which may be covered by a registration statement, and (ii) notify Parent’s transfer agent in writing of such stop order and the restrictions on such Shares under Section 2(b) and direct Parent’s transfer agent not to process any attempts by any Holder to Transfer any Shares except in compliance with this Section 2(b).

Notwithstanding the foregoing, to the extent any Holder is granted a release or waiver to a substantially similar lockup to those set forth in the restrictions contained in this Section 2 prior to the expiration of the Lock-Up Period, then all Holders subject to such restrictions shall be automatically granted a release or waiver from the restrictions contained in this Section 2 to the same extent, on substantially the same terms as and on a pro rata basis with, the Holder to which such release or waiver is granted.

Section 3. Certain Covenants of the Holder.

(b) this Agreement has been duly executed and delivered by such Holder and, assuming due authorization, execution and delivered by the other Parties, constitutes a valid, legal and binding agreement with respect to such Holder, enforceable against such Holder in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or similar Laws affecting creditors’ rights generally and general principles of equity;

Statement will, at the time the Registration Statement/Proxy Statement is filed with the SEC, at each time at which it is amended, or at the time it becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading.”

(3) Survival of Rights. The rights of indemnification provided by this Section 2 shall continue as to a Director or Officer after he or she has ceased to be a Director or Officer and shall inure to the benefit of his or her heirs, executors, administrators and personal representatives.

(4) Actions by Directors or Officers. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by such Director or Officer only if such Proceeding (including any parts of such Proceeding not initiated by such Director or Officer) was authorized in advance by the Board of Directors of the Corporation, unless such Proceeding was brought to enforce such Officer’s or Director’s rights to indemnification or, in the case of Directors, advancement of Expenses under this Certificate in accordance with the provisions set forth herein.

3. Indemnification of Non-Officer Employees. Subject to the operation of Section 4 of this Article VIII, each Non-Officer Employee may, in the discretion of the Board of Directors, be indemnified by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses and Liabilities that are incurred by such Non-Officer Employee or on such Non-Officer Employee’s behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee’s Corporate Status, if such Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal

B-6

representatives, executors and administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such Non-Officer Employee only if such Proceeding was authorized in advance by the Board of Directors.

4. Determination. Unless ordered by a court, no indemnification shall be provided pursuant to this Article VIII to a Director, to an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. Such determination shall be made by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board of Directors, (b) a committee comprised of Disinterested Directors, such committee having been designated by a majority vote of the Disinterested Directors (even though less than a quorum), (c) if there are no such Disinterested Directors, or if a majority of Disinterested Directors so directs, by independent legal counsel in a written opinion, or (d) by the stockholders of the Corporation.

5. Advancement of Expenses to Directors Prior to Final Disposition.

(a) The Corporation shall advance all Expenses incurred by or on behalf of any Director in connection with any Proceeding in which such Director is involved by reason of such Director’s Corporate Status within thirty (30) days after the receipt by the Corporation of a written statement from such Director requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Director and shall be preceded or accompanied by an undertaking by or on behalf of such Director to repay any Expenses so advanced if it shall ultimately be determined that such Director is not entitled to be indemnified against such Expenses. Notwithstanding the foregoing, the Corporation shall advance all Expenses incurred by or on behalf of any Director seeking advancement of expenses hereunder in connection with a Proceeding initiated by such Director only if such Proceeding (including any parts of such Proceeding not initiated by such Director) was (i) authorized by the Board of Directors or (ii) brought to enforce such Director’s rights to indemnification or advancement of Expenses under this Certificate.

(b) If a claim for advancement of Expenses hereunder by a Director is not paid in full by the Corporation within thirty (30) days after receipt by the Corporation of documentation of Expenses and the required undertaking, such Director may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and if successful in whole or in part, such Director shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article VIII shall not be a defense to an action brought by a Director for recovery of the unpaid amount of an advancement claim and shall not create a presumption that such advancement is not permissible. The burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation.

(c) In any suit brought by the Corporation to recover an advancement of Expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such Expenses upon a final adjudication that the Director has not met any applicable standard for indemnification set forth in the DGCL.

6. Advancement of Expenses to Officers and Non-Officer Employees Prior to Final Disposition.

B-7

Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer or Non-Officer Employee and shall be preceded or accompanied by an undertaking by or on behalf of such person to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified against such Expenses.

(b) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Officer or Non-Officer Employee has not met any applicable standard for indemnification set forth in the DGCL.

7. Contractual Nature of Rights.

(a) The provisions of this Article VIII shall be deemed to be a contract between the Corporation and each Director and Officer entitled to the benefits hereof at any time while this Article VIII is in effect, in consideration of such person’s past or current and any future performance of services for the Corporation. Neither amendment, repeal or modification of any provision of this Article VIII nor the adoption of any provision of the Bylaws inconsistent with this Article VIII shall eliminate or reduce any right conferred by this Article VIII in respect of any act or omission occurring, or any cause of action or claim that accrues or arises or any state of facts existing, at the time of or before such amendment, repeal, modification or adoption of an inconsistent provision (even in the case of a proceeding based on such a state of facts that is commenced after such time), and all rights to indemnification and advancement of Expenses granted herein or arising out of any act or omission shall vest at the time of the act or omission in question, regardless of when or if any proceeding with respect to such act or omission is commenced. The rights to indemnification and to advancement of expenses provided by, or granted pursuant to, this Article VIII shall continue notwithstanding that the person has ceased to be a Director or Officer of the Corporation and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributes of such person.

(b) If a claim for indemnification hereunder by a Director or Officer is not paid in full by the Corporation within sixty (60) days after receipt by the Corporation of a written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such indemnification under this Article VIII shall not be a defense to an action brought by a Director or Officer for recovery of the unpaid amount of an indemnification claim and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation.

(c) In any suit brought by a Director or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Director or Officer has not met any applicable standard for indemnification set forth in the DGCL.

8. Non-Exclusivity of Rights. The rights to indemnification and to advancement of Expenses set forth in this Article VIII shall not be exclusive of any other right which any Director, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Bylaws or this Certificate, agreement, vote of stockholders or Disinterested Directors or otherwise.

9. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer Employee, or arising out of any such person’s Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article VIII.

B-8

10. Other Indemnification. The Corporation’s obligation, if any, to indemnify or provide advancement of Expenses to any person under this Article VIII as a result of such person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person may collect as indemnification or advancement of Expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise (the “Primary Indemnitor”). Any indemnification or advancement of Expenses under this Article VIII owed by the Corporation as a result of a person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall only be in excess of, and shall be secondary to, the indemnification or advancement of Expenses available from the applicable Primary Indemnitor(s) and any applicable insurance policies.

SECTION 1. Annual Meeting. The annual meeting of stockholders (any such meeting being referred to in these Bylaws as an “Annual Meeting”) shall be held at the hour, date and place within or without the United States which is fixed by the Corporation’s Board of Directors (the “Board of Directors”), which time, date and place may subsequently be changed at any time by vote of the Board of Directors. If no Annual Meeting has been held for a period of thirteen (13) months after the Corporation’s last Annual Meeting, a special meeting in lieu thereof may be held, and such special meeting shall have, for the purposes of these Bylaws or otherwise, all the force and effect of an Annual Meeting. Any and all references hereafter in these Bylaws to an Annual Meeting or Annual Meetings also shall be deemed to refer to any special meeting(s) in lieu thereof.

SECTION 2. Notice of Stockholder Business and Nominations.

(a) Annual Meetings of Stockholders.

(1) Nominations of persons for election to the Board of Directors and the proposal of other business to be considered by the stockholders may be brought before an Annual Meeting (i) by or at the direction of the Board of Directors or (ii) by any stockholder of the Corporation who was a stockholder of record at the time of giving of notice provided for in this Bylaw, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who complies with the notice procedures set forth in this Bylaw as to such nomination or business. For the avoidance of doubt, the foregoing clause (ii) shall be the exclusive means for a stockholder to bring nominations or business properly before an Annual Meeting (other than matters properly brought under Rule 14a-8 (or any successor rule) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), and such stockholder must comply with the notice and other procedures set forth in Article I, Section 2(a)(2) and (3) of this Bylaw to bring such nominations or business properly before an Annual Meeting. In addition to the other requirements set forth in this Bylaw, for any proposal of business to be considered at an Annual Meeting, it must be a proper subject for action by stockholders of the Corporation under Delaware law.

(2) For nominations or other business to be properly brought before an Annual Meeting by a stockholder pursuant to clause (ii) of Article I, Section 2(a)(1) of this Bylaw, the stockholder must (i) have given Timely Notice (as defined below) thereof in writing to the Secretary of the Corporation, (ii) have provided any updates or supplements to such notice at the times and in the forms required by this Bylaw and (iii) together with the beneficial owner(s), if any, on whose behalf the nomination or business proposal is made, have acted in accordance with the representations set forth in the Solicitation Statement (as defined below) required by this Bylaw.

following the day on which public announcement of the date of such meeting is first made (such notice within such time periods shall be referred to as “Timely Notice”). Such stockholder’s Timely Notice shall set forth:

For purposes of this Article I of these Bylaws, the term “Proposing Person” shall mean the following persons: (i) the stockholder of record providing the notice of nominations or business proposed to be brought before a stockholders’ meeting, and (ii) the beneficial owner(s), if different, on whose behalf the nominations or business proposed to be brought before a stockholders’ meeting is made. For purposes of this Section 2 of Article I of these Bylaws, the term “Synthetic Equity Interest” shall mean any transaction, agreement or arrangement (or series of transactions, agreements or arrangements), including, without limitation, any derivative, swap, hedge, repurchase or so-called “stock borrowing” agreement or arrangement, the purpose or effect of which is to, directly or indirectly: (a) give a person or entity economic benefit and/or risk similar to ownership of shares of any class or series of capital stock of the Corporation, in whole or in part, including due to the fact that such transaction, agreement or arrangement provides, directly or indirectly, the opportunity to profit or avoid a loss from any increase or decrease in the value of any shares of any class or series of capital stock of the Corporation, (b) mitigate loss to, reduce the economic risk of or manage the risk of share price changes for, any person or entity with respect to any shares of any class or series of capital stock of the Corporation, (c) otherwise provide in any manner the opportunity to profit or avoid a loss from any decrease in the value of any shares of any class or series of capital stock of the Corporation, or (d) increase or decrease the voting power of any person or entity with respect to any shares of any class or series of capital stock of the Corporation.

(3) A stockholder providing Timely Notice of nominations or business proposed to be brought before an Annual Meeting shall further update and supplement such notice, if necessary, so that the information (including, without limitation, the Material Ownership Interests information) provided or required to be provided in such notice pursuant to this Bylaw shall be true and correct as of the record date for the meeting and as of the date that is ten (10) business days prior to such Annual Meeting, and such update and supplement shall be received by the Secretary at the principal executive offices of the Corporation not later than the close of business on the fifth (5th) business day after the record date for the Annual Meeting (in the case of the update and supplement required to be made as of the record date), and not later than the close of business on the eighth (8th) business day prior to the date of the Annual Meeting (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting).

(4) Notwithstanding anything in the second sentence of Article I, Section 2(a)(2) of this Bylaw to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Corporation is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least ten (10) days before the last day a stockholder may deliver a notice of nomination in accordance with the second sentence of Article I, Section 2(a)(2), a stockholder’s notice required by this Bylaw shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be received by the Secretary of the Corporation not later than the close of business on the tenth (10th) day following the day on which such public announcement is first made by the Corporation.

(b) General.

(1) Only such persons who are nominated in accordance with the provisions of this Bylaw shall be eligible for election and to serve as directors and only such business shall be conducted at an Annual

B-13

Meeting as shall have been brought before the meeting in accordance with the provisions of this Bylaw or in accordance with Rule 14a-8 under the Exchange Act. The Board of Directors or a designated committee thereof shall have the power to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the provisions of this Bylaw. If neither the Board of Directors nor such designated committee makes a determination as to whether any stockholder proposal or nomination was made in accordance with the provisions of this Bylaw, the presiding officer of the Annual Meeting shall have the power and duty to determine whether the stockholder proposal or nomination was made in accordance with the provisions of this Bylaw. If the Board of Directors or a designated committee thereof or the presiding officer, as applicable, determines that any stockholder proposal or nomination was not made in accordance with the provisions of this Bylaw, such proposal or nomination shall be disregarded and shall not be presented for action at the Annual Meeting.

(2) Except as otherwise required by law, nothing in this Article I, Section 2 shall obligate the Corporation or the Board of Directors to include in any proxy statement or other stockholder communication distributed on behalf of the Corporation or the Board of Directors information with respect to any nominee for director or any other matter of business submitted by a stockholder.

(3) Notwithstanding the foregoing provisions of this Article I, Section 2, if the nominating or proposing stockholder (or a qualified representative of the stockholder) does not appear at the Annual Meeting to present a nomination or any business, such nomination or business shall be disregarded, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Article I, Section 2, to be considered a qualified representative of the proposing stockholder, a person must be authorized by a written instrument executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such written instrument or electronic transmission, or a reliable reproduction of the written instrument or electronic transmission, to the presiding officer at the meeting of stockholders.

(4) For purposes of this Bylaw, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(5) Notwithstanding the foregoing provisions of this Bylaw, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Bylaw. Nothing in this Bylaw shall be deemed to affect any rights of (i) stockholders to have proposals included in the Corporation’s proxy statement pursuant to Rule 14a-8 (or any successor rule), as applicable, under the Exchange Act and, to the extent required by such rule, have such proposals considered and voted on at an Annual Meeting or (ii) the holders of any series of Undesignated Preferred Stock to elect directors under specified circumstances.

SECTION 3. Special Meetings. Except as otherwise required by statute and subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office. The Board of Directors may postpone or reschedule any previously scheduled special meeting of stockholders. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation. Nominations of persons for election to the Board of Directors of the Corporation and stockholder proposals of other business shall not be brought before a special meeting of stockholders to be considered by the stockholders unless such special meeting is held in lieu of an annual meeting of stockholders in accordance with Article I, Section 1 of these Bylaws, in which case such special meeting in lieu thereof shall be deemed an Annual Meeting for purposes of these Bylaws and the provisions of Article I, Section 2 of these Bylaws shall govern such special meeting.

B-14

SECTION 4. Notice of Meetings; Adjournments.

(a) A notice of each Annual Meeting stating the hour, date and place, if any, of such Annual Meeting and the means of remote communication, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, shall be given not less than ten (10) days nor more than sixty (60) days before the Annual Meeting, to each stockholder entitled to vote thereat by delivering such notice to such stockholder or by mailing it, postage prepaid, addressed to such stockholder at the address of such stockholder as it appears on the Corporation’s stock transfer books. Without limiting the manner by which notice may otherwise be given to stockholders, any notice to stockholders may be given by electronic transmission in the manner provided in Section 232 of the Delaware General Corporation Law (“DGCL”).

(b) Notice of all special meetings of stockholders shall be given in the same manner as provided for Annual Meetings, except that the notice of all special meetings shall state the purpose or purposes for which the meeting has been called.

(c) Notice of an Annual Meeting or special meeting of stockholders need not be given to a stockholder if a waiver of notice is executed, or waiver of notice by electronic transmission is provided, before or after such meeting by such stockholder or if such stockholder attends such meeting, unless such attendance is for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting was not lawfully called or convened.

(d) The Board of Directors may postpone and reschedule any previously scheduled Annual Meeting or special meeting of stockholders and any record date with respect thereto, regardless of whether any notice or public disclosure with respect to any such meeting has been sent or made pursuant to Section 2 of this Article I of these Bylaws or otherwise. In no event shall the public announcement of an adjournment, postponement or rescheduling of any previously scheduled meeting of stockholders commence a new time period for the giving of a stockholder’s notice under this Article I of these Bylaws.

(e) When any meeting is convened, the presiding officer may adjourn the meeting if (i) no quorum is present for the transaction of business, (ii) the Board of Directors determines that adjournment is necessary or appropriate to enable the stockholders to consider fully information which the Board of Directors determines has not been made sufficiently or timely available to stockholders, or (iii) the Board of Directors determines that adjournment is otherwise in the best interests of the Corporation. When any Annual Meeting or special meeting of stockholders is adjourned to another hour, date or place, notice need not be given of the adjourned meeting other than an announcement at the meeting at which the adjournment is taken of the hour, date and place, if any, to which the meeting is adjourned and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting; provided, however, that if the adjournment is for more than thirty (30) days from the meeting date, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting shall be given to each stockholder of record entitled to vote thereat and each stockholder who, by law or under the Certificate of Incorporation of the Corporation (as the same may hereafter be amended and/or restated, the “Certificate”) or these Bylaws, is entitled to such notice.

SECTION 5. Quorum. A majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders. If less than a quorum is present at a meeting, the holders of voting stock representing a majority of the voting power present at the meeting or the presiding officer may adjourn the meeting from time to time, and the meeting may be held as adjourned without further notice, except as provided in Section 4 of this Article I. At such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. The stockholders present at a duly constituted meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

B-15

SECTION 6. Voting and Proxies. Stockholders shall have one vote for each share of stock entitled to vote owned by them of record according to the stock ledger of the Corporation as of the record date, unless otherwise provided by law or by the Certificate. Stockholders may vote either (i) in person, (ii) by written proxy or (iii) by a transmission permitted by Section 212(c) of the DGCL. Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission permitted by Section 212(c) of the DGCL may be substituted for or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission. Proxies shall be filed in accordance with the procedures established for the meeting of stockholders. Except as otherwise limited therein or as otherwise provided by law, proxies authorizing a person to vote at a specific meeting shall entitle the persons authorized thereby to vote at any adjournment of such meeting, but they shall not be valid after final adjournment of such meeting. A proxy with respect to stock held in the name of two or more persons shall be valid if executed by or on behalf of any one of them unless at or prior to the exercise of the proxy the Corporation receives a specific written notice to the contrary from any one of them.

SECTION 7. Action at Meeting. When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an election of a director or directors) shall be decided by a majority of the votes properly cast for and against such matter, except where a larger vote is required by law, by the Certificate or by these Bylaws. Any election of directors by stockholders shall be determined by a plurality of the votes properly cast on the election of directors.

SECTION 8. Stockholder Lists. The Secretary or an Assistant Secretary (or the Corporation’s transfer agent or other person authorized by these Bylaws or by law) shall prepare and make, at least ten (10) days before every Annual Meeting or special meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for a period of at least ten (10) days prior to the meeting in the manner provided by law.

SECTION 3. Record Holders. Except as may otherwise be required by law, by the Certificate or by these Bylaws, the Corporation shall be entitled to treat the record holder of stock as shown on its books as the owner of such stock for all purposes, including the payment of dividends and the right to vote with respect thereto, regardless of any transfer, pledge or other disposition of such stock, until the shares have been transferred on the books of the Corporation in accordance with the requirements of these Bylaws.

dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date: (a) in the case of determination of stockholders entitled to vote at any meeting of stockholders, shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting and (b) in the case of any other action, shall not be more than sixty (60) days prior to such other action.

(a) Subject to the operation of Section 4 of this Article V of these Bylaws, each Director and Officer shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), and to the extent authorized in this Section 2.

B-23

Liabilities that are incurred or paid by such Director or Officer or on such Director’s or Officer’s behalf in connection with any Proceeding or any claim, issue or matter therein (other than an action by or in the right of the Corporation), which such Director or Officer is, or is threatened to be made, a party to or participant in by reason of such Director’s or Officer’s Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.

(4) Actions by Directors or Officers. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by such Director or Officer only if such Proceeding (including any parts of such Proceeding not initiated by such Director or Officer) was authorized in advance by the Board of Directors of the Corporation, unless such Proceeding was brought to enforce such Officer’s or Director’s rights to indemnification or, in the case of Directors, advancement of Expenses under these Bylaws in accordance with the provisions set forth herein.

SECTION 3. Indemnification of Non-Officer Employees. Subject to the operation of Section 4 of this Article V of these Bylaws, each Non-Officer Employee may, in the discretion of the Board of Directors, be indemnified by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses and Liabilities that are incurred by such Non-Officer Employee or on such Non-Officer Employee’s behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee’s Corporate Status, if such Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal representatives, executors and administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such Non-Officer Employee only if such Proceeding was authorized in advance by the Board of Directors.

SECTION 4. Determination. Unless ordered by a court, no indemnification shall be provided pursuant to this Article V to a Director, to an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no

B-24

reasonable cause to believe his or her conduct was unlawful.

The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article V shall not be a defense to an action brought by a Director for recovery of the unpaid amount of an advancement claim and shall not create a presumption that such advancement is not permissible. The burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation.

SECTION 6. Advancement of Expenses to Officers and Non-Officer Employees Prior to Final Disposition.

(a) The Corporation may, at the discretion of the Board of Directors, advance any or all Expenses incurred by or on behalf of any Officer or any Non-Officer Employee in connection with any Proceeding in which such person is involved by reason of his or her Corporate Status as an Officer or Non-Officer Employee upon the receipt by the Corporation of a statement or statements from such Officer or Non-Officer Employee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer or Non-Officer Employee and shall be preceded or accompanied by an undertaking by or on behalf of such person to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified against such Expenses.

B-25

SECTION 7. Contractual Nature of Rights.

(a) The provisions of this Article V shall be deemed to be a contract between the Corporation and each Director and Officer entitled to the benefits hereof at any time while this Article V is in effect, in consideration of such person’s past or current and any future performance of services for the Corporation. Neither amendment, repeal or modification of any provision of this Article V nor the adoption of any provision of the Certificate of Incorporation inconsistent with this Article V shall eliminate or reduce any right conferred by this Article V in respect of any act or omission occurring, or any cause of action or claim that accrues or arises or any state of facts existing, at the time of or before such amendment, repeal, modification or adoption of an inconsistent provision (even in the case of a proceeding based on such a state of facts that is commenced after such time), and all rights to indemnification and advancement of Expenses granted herein or arising out of any act or omission shall vest at the time of the act or omission in question, regardless of when or if any proceeding with respect to such act or omission is commenced. The rights to indemnification and to advancement of expenses provided by, or granted pursuant to, this Article V shall continue notwithstanding that the person has ceased to be a Director or Officer of the Corporation and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributes of such person.

(b) If a claim for indemnification hereunder by a Director or Officer is not paid in full by the Corporation within sixty (60) days after receipt by the Corporation of a written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such indemnification under this Article V shall not be a defense to an action brought by a Director or Officer for recovery of the unpaid amount of an indemnification claim and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation.

SECTION 8. Non-Exclusivity of Rights. The rights to indemnification and to advancement of Expenses set forth in this Article V shall not be exclusive of any other right which any Director, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Certificate or these Bylaws, agreement, vote of stockholders or Disinterested Directors or otherwise.

The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer Employee, or arising out of any such person’s Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article V.

SECTION 10. Other Indemnification. The Corporation’s obligation, if any, to indemnify or provide advancement of Expenses to any person under this Article V as a result of such person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person may collect as indemnification or advancement of Expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise (the “Primary Indemnitor”). Any indemnification or advancement of Expenses under this Article V owed by the Corporation as a result of a person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall only be in excess of, and shall be secondary to, the

B-26

1.	GENERAL.

(a) Plan Purpose. The Company, by means of the Plan, seeks to secure and retain the services of Employees, Directors and Consultants, to provide incentives for such persons to exert maximum efforts for the success of the Company and any Affiliate and to provide a means by which such persons may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Awards.

(b) Available Awards. The Plan provides for the grant of the following Awards: (i) Incentive Stock Options; (ii) Nonstatutory Stock Options; (iii) SARs; (iv) Restricted Stock Awards; (v) RSU Awards; (vi) Performance Awards; and (vii) Other Awards.

(c) Adoption Date; Effective Date. The Plan will come into existence on the Adoption Date, but no Award may be granted prior to the Effective Date.

2.	SHARES SUBJECT TO THE PLAN.

(a) Share Reserve. Subject to adjustment in accordance with Section 2(c) and any adjustments as necessary to implement any Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Awards will not exceed the sum of: (i) [●] new shares¹, plus (ii) the number of Returning Shares, if any, as such shares become available from time to time. In addition, subject to any adjustments as necessary to implement any Capitalization Adjustments, such aggregate number of shares of Common Stock will automatically increase on January 1st of each year for a period of ten years commencing on January 1, 2023 and ending on (and including) January 1, 2032, in an amount equal to five percent (5%) of the total number of shares of Common Stock outstanding on the last day of the preceding calendar year; provided, however that the Board may act prior to the effective date of any such annual increase to provide that the increase for such year will be a lesser number of shares of Common Stock.

(b) Aggregate Incentive Stock Option Limit. Notwithstanding anything to the contrary in Section 2(a) and subject to any adjustments as necessary to implement any Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options is [●] shares.

(c) Share Reserve Operation.

(i) Limit Applies to Common Stock Issued Pursuant to Awards. For clarity, the Share Reserve is a limit on the number of shares of Common Stock that may be issued pursuant to Awards and does not limit the granting of Awards, except that the Company will keep available at all times the number of shares of Common Stock reasonably required to satisfy its obligations to issue shares pursuant to such Awards. Shares may be issued in connection with a merger or acquisition as permitted by, as applicable, Nasdaq Listing Rule 5635(c), NYSE Listed Company Manual Section 303A.08, NYSE American Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance under the Plan.

(ii) Actions that Do Not Constitute Issuance of Common Stock and Do Not Reduce Share Reserve. The following actions do not result in an issuance of shares under the Plan and accordingly do not reduce the number of shares subject to the Share Reserve and available for issuance under the Plan: (1) the expiration or termination of any portion of an Award without the shares covered by such portion of the Award having been issued; (2) the settlement of any portion of an Award in cash (i.e., the Participant receives cash rather than Common Stock); (3) the withholding of shares that would otherwise be issued by the Company to

¹	Note to Draft: A number of shares equal to 22% of shares of Common Stock issued and outstanding immediately after the closing of the Merger, less the number of shares subject to Closing Option Awards (approximately 15%, depending on redemptions).

C-1

satisfy the exercise, strike or purchase price of an Award; or (4) the withholding of shares that would otherwise be issued by the Company to satisfy a tax withholding obligation in connection with an Award.

(iii) Reversion of Previously Issued Shares of Common Stock to Share Reserve. The following shares of Common Stock previously issued pursuant to an Award and accordingly initially deducted from the Share Reserve will be added back to the Share Reserve and again become available for issuance under the Plan: (1) any shares that are forfeited back to or repurchased by the Company because of a failure to meet a contingency or condition required for the vesting of such shares; (2) any shares that are reacquired by the Company to satisfy the exercise, strike or purchase price of an Award; and (3) any shares that are reacquired by the Company to satisfy a tax withholding obligation in connection with an Award.

3.	ELIGIBILITY AND LIMITATIONS.

(a) Eligible Award Recipients. Subject to the terms of the Plan, Employees, Directors and Consultants are eligible to receive Awards.

(b) Specific Award Limitations.

(i) Limitations on Incentive Stock Option Recipients. Incentive Stock Options may be granted only to Employees of the Company or a “parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and (f) of the Code).

(ii) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any Affiliates) exceeds $100,000 (or such other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or otherwise do not comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s).

(iii) Limitations on Incentive Stock Options Granted to Ten Percent Stockholders. A Ten Percent Stockholder may not be granted an Incentive Stock Option unless (i) the exercise price of such Option is at least 110% of the Fair Market Value on the date of grant of such Option and (ii) the Option is not exercisable after the expiration of five years from the date of grant of such Option.

(iv) Limitations on Nonstatutory Stock Options and SARs. Nonstatutory Stock Options and SARs may not be granted to Employees, Directors and Consultants who are providing Continuous Service only to any “parent” of the Company (as such term is defined in Rule 405) unless the stock underlying such Awards is treated as “service recipient stock” under Section 409A because the Awards are granted pursuant to a corporate transaction (such as a spin off transaction) or unless such Awards otherwise comply with the distribution requirements of Section 409A.

(c) Aggregate Incentive Stock Option Limit. The aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options is the number of shares specified in Section 2(b).

(d) Non-Employee Director Compensation Limit. The aggregate value of all compensation granted or paid, as applicable, to any individual for service as a Non-Employee Director with respect to any calendar year, including Awards granted and cash fees paid by the Company to such Non-Employee Director, will not exceed (i) $750,000 in total value or (ii) in the event such Non-Employee Director is first appointed or elected to the Board during such calendar year, $1,000,000 in total value, in each case calculating the value of any equity awards based on the grant date fair value of such equity awards for financial reporting purposes. The limitations in this Section 3(d) shall apply beginning with the first calendar year that commences following the Effective Date.

C-2

4.	OPTIONS AND STOCK APPRECIATION RIGHTS.

Each Option and SAR will have such terms and conditions as determined by the Board. Each Option will be designated in writing as an Incentive Stock Option or Nonstatutory Stock Option at the time of grant; provided, however, that if an Option is not so designated, then such Option will be a Nonstatutory Stock Option. The shares purchased upon exercise of each type of Option will be accounted for separately. Each SAR will be denominated in shares of Common Stock equivalents. The terms and conditions of separate Options and SARs need not be identical; provided, however, that each Option Agreement and SAR Agreement will conform (through incorporation of provisions hereof by reference in the Award Agreement or otherwise) to the substance of each of the following provisions:

(a) Term. Subject to Section 3(b) regarding Incentive Stock Options granted to Ten Percent Stockholders, no Option or SAR will be exercisable after the expiration of ten years from the date of grant of such Award or such shorter period specified in the Award Agreement.

(b) Exercise or Strike Price. Subject to Section 3(b) regarding Ten Percent Stockholders, the exercise or strike price of each Option or SAR will not be less than 100% of the Fair Market Value on the date of grant of such Award. Notwithstanding the foregoing, an Option or SAR may be granted with an exercise or strike price lower than 100% of the Fair Market Value on the date of grant of such Award if such Award is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Sections 409A and, if applicable, 424(a) of the Code.

(c) Exercise Procedure and Payment of Exercise Price for Options. In order to exercise an Option, the Participant must provide notice of exercise to the Plan Administrator in accordance with the procedures specified in the Option Agreement or otherwise provided by the Company. The Board has the authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment. The exercise price of an Option may be paid, to the extent permitted by Applicable Law and as determined by the Board, by one or more of the following methods of payment to the extent set forth in the Option Agreement:

(i) by cash or check, bank draft or money order (or an electronic equivalent thereof) payable to the Company;

(ii) pursuant to a “cashless exercise” program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of the Common Stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the exercise price to the Company from the sales proceeds;

(iii) by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock that are already owned by the Participant free and clear of any liens, claims, encumbrances or security interests, with a Fair Market Value on the date of exercise that does not exceed the exercise price, provided that (1) at the time of exercise the Common Stock is publicly traded, (2) any remaining balance of the exercise price not satisfied by such delivery is paid by the Participant in cash or other permitted form of payment, (3) such delivery would not violate any Applicable Law or agreement restricting the redemption of the Common Stock, (4) any certificated shares are endorsed or accompanied by an executed assignment separate from certificate, and (5) such shares have been held by the Participant for any minimum period necessary to avoid adverse accounting treatment as a result of such delivery;

(iv) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value on the date of exercise that does not exceed the exercise price, provided that (1) such shares used to pay the

C-3

exercise price will not be exercisable thereafter and (2) any remaining balance of the exercise price not satisfied by such net exercise is paid by the Participant in cash or other permitted form of payment; or

(v) in any other form of consideration that may be acceptable to the Board and permissible under Applicable Law.

(d) Exercise Procedure and Payment of Appreciation Distribution for SARs. In order to exercise any SAR, the Participant must provide notice of exercise to the Plan Administrator in accordance with the SAR Agreement. The appreciation distribution payable to a Participant upon the exercise of a SAR will not be greater than an amount equal to the excess of (i) the aggregate Fair Market Value on the date of exercise of a number of shares of Common Stock equal to the number of Common Stock equivalents that are vested and being exercised under such SAR, over (ii) the strike price of such SAR. Such appreciation distribution may be paid to the Participant in the form of Common Stock or cash (or any combination of Common Stock and cash) or in any other form of payment, as determined by the Board and specified in the SAR Agreement.

(e) Transferability. Options and SARs may not be transferred to third party financial institutions for value. The Board may impose such additional limitations on the transferability of an Option or SAR as it determines. In the absence of any such determination by the Board, the following restrictions on the transferability of Options and SARs will apply, provided that except as explicitly provided herein, neither an Option nor a SAR may be transferred for consideration and provided, further, that if an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer:

(i) Restrictions on Transfer. An Option or SAR will not be transferable, except by will or by the laws of descent and distribution, and will be exercisable during the lifetime of the Participant only by the Participant; provided, however, that the Board may permit transfer of an Option or SAR in a manner that is not prohibited by applicable tax and securities laws upon the Participant’s request, including to a trust if the Participant is considered to be the sole beneficial owner of such trust (as determined under Section 671 of the Code and applicable state law) while such Option or SAR is held in such trust, provided that the Participant and the trustee enter into a transfer and other agreements required by the Company.

(ii) Domestic Relations Orders. Notwithstanding the foregoing, subject to the execution of transfer documentation in a format acceptable to the Company and subject to the approval of the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to a domestic relations order.

(f) Vesting. The Board may impose such restrictions on or conditions to the vesting and/or exercisability of an Option or SAR as determined by the Board. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, vesting of Options and SARs will cease upon termination of the Participant’s Continuous Service.

(g) Termination of Continuous Service for Cause. Except as explicitly otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service is terminated for Cause, the Participant’s Options and SARs will terminate and be forfeited immediately upon such termination of Continuous Service, and the Participant will be prohibited from exercising any portion (including any vested portion) of such Awards on and after the date of such termination of Continuous Service and the Participant will have no further right, title or interest in such forfeited Award, the shares of Common Stock subject to the forfeited Award, or any consideration in respect of the forfeited Award.

(h) Post-Termination Exercise Period Following Termination of Continuous Service for Reasons Other than Cause. Subject to Section 4(i), if a Participant’s Continuous Service terminates for any reason other than for Cause, the Participant may exercise his or her Option or SAR to the extent vested, but only within the following period of time or, if applicable, such other period of time provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate; provided, however, that in no event may such Award be exercised after the expiration of its maximum term (as set forth in Section 4(a)):

C-4

(i) three months following the date of such termination if such termination is a termination without Cause (other than any termination due to the Participant’s Disability or death);

(ii) 12 months following the date of such termination if such termination is due to the Participant’s Disability;

(iii) 18 months following the date of such termination if such termination is due to the Participant’s death; or

(iv) 18 months following the date of the Participant’s death if such death occurs following the date of such termination but during the period such Award is otherwise exercisable (as provided in (i) or (ii) above).

Following the date of such termination, to the extent the Participant does not exercise such Award within the applicable Post-Termination Exercise Period (or, if earlier, prior to the expiration of the maximum term of such Award), such unexercised portion of the Award will terminate, and the Participant will have no further right, title or interest in the terminated Award, the shares of Common Stock subject to the terminated Award, or any consideration in respect of the terminated Award.

(i) Restrictions on Exercise; Extension of Exercisability. A Participant may not exercise an Option or SAR at any time that the issuance of shares of Common Stock upon such exercise would violate Applicable Law. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates for any reason other than for Cause and, at any time during the last thirty days of the applicable Post-Termination Exercise Period: (i) the exercise of the Participant’s Option or SAR would be prohibited solely because the issuance of shares of Common Stock upon such exercise would violate Applicable Law, or (ii) the immediate sale of any shares of Common Stock issued upon such exercise would violate the Company’s Trading Policy, then the applicable Post-Termination Exercise Period will be extended to the last day of the calendar month that commences following the date the Award would otherwise expire, with an additional extension of the exercise period to the last day of the next calendar month to apply if any of the foregoing restrictions apply at any time during such extended exercise period, generally without limitation as to the maximum permitted number of extensions); provided, however, that in no event may such Award be exercised after the expiration of its maximum term (as set forth in Section 4(a)).

(j) Non-Exempt Employees. No Option or SAR, whether or not vested, granted to an Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, will be first exercisable for any shares of Common Stock until at least six months following the date of grant of such Award. Notwithstanding the foregoing, in accordance with the provisions of the Worker Economic Opportunity Act, any vested portion of such Award may be exercised earlier than six months following the date of grant of such Award in the event of (i) such Participant’s death or Disability, (ii) a Corporate Transaction in which such Award is not assumed, continued or substituted, (iii) a Change in Control, or (iv) such Participant’s retirement (as such term may be defined in the Award Agreement or another applicable agreement or, in the absence of any such definition, in accordance with the Company’s then current employment policies and guidelines). This Section 4(j) is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from their regular rate of pay.

(k) Whole Shares. Options and SARs may be exercised only with respect to whole shares of Common Stock or their equivalents.

5.	AWARDS OTHER THAN OPTIONS AND STOCK APPRECIATION RIGHTS.

(a) Restricted Stock Awards and RSU Awards. Each Restricted Stock Award and RSU Award will have such terms and conditions as determined by the Board; provided, however, that each Restricted Stock Award Agreement and RSU Award Agreement will conform (through incorporation of the provisions hereof by reference in the Award Agreement or otherwise) to the substance of each of the following provisions:

C-5

(i) Form of Award.

(1) RSAs. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock subject to a Restricted Stock Award may be (A) held in book entry form subject to the Company’s instructions until such shares become vested or any other restrictions lapse, or (B) evidenced by a certificate, which certificate will be held in such form and manner as determined by the Board. Unless otherwise determined by the Board, a Participant will have voting and other rights as a stockholder of the Company with respect to any shares subject to a Restricted Stock Award.

(2) RSUs. An RSU Award represents a Participant’s right to be issued on a future date the number of shares of Common Stock that is equal to the number of restricted stock units subject to the RSU Award. As a holder of an RSU Award, a Participant is an unsecured creditor of the Company with respect to the Company’s unfunded obligation, if any, to issue shares of Common Stock in settlement of such Award and nothing contained in the Plan or any RSU Agreement, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between a Participant and the Company or an Affiliate or any other person. A Participant will not have voting or any other rights as a stockholder of the Company with respect to any RSU Award (unless and until shares are actually issued in settlement of a vested RSU Award).

(ii) Consideration.

(1) RSA. A Restricted Stock Award may be granted in consideration for (A) cash or check, bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of consideration (including future services) as the Board may determine and permissible under Applicable Law.

(2) RSU. Unless otherwise determined by the Board at the time of grant, an RSU Award will be granted in consideration for the Participant’s services to the Company or an Affiliate, such that the Participant will not be required to make any payment to the Company (other than such services) with respect to the grant or vesting of the RSU Award, or the issuance of any shares of Common Stock pursuant to the RSU Award. If, at the time of grant, the Board determines that any consideration must be paid by the Participant (in a form other than the Participant’s services to the Company or an Affiliate) upon the issuance of any shares of Common Stock in settlement of the RSU Award, such consideration may be paid in any form of consideration as the Board may determine and permissible under Applicable Law.

(iii) Vesting. The Board may impose such restrictions on or conditions to the vesting of a Restricted Stock Award or RSU Award as determined by the Board. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, vesting of Restricted Stock Awards and RSU Awards will cease upon termination of the Participant’s Continuous Service.

(iv) Termination of Continuous Service. Except as otherwise provided in the Award Agreement or other written agreement between a Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates for any reason, (1) the Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant under their Restricted Stock Award that have not vested as of the date of such termination as set forth in the Restricted Stock Award Agreement and (2) any portion of their RSU Award that has not vested will be forfeited upon such termination and the Participant will have no further right, title or interest in the RSU Award, the shares of Common Stock issuable pursuant to the RSU Award, or any consideration in respect of the RSU Award.

(v) Dividends and Dividend Equivalents. Dividends or dividend equivalents may be paid or credited, as applicable, with respect to any shares of Common Stock subject to a Restricted Stock Award or RSU Award, as determined by the Board and specified in the Award Agreement).

C-6

(vi) Settlement of RSU Awards. An RSU Award may be settled by the issuance of shares of Common Stock or cash (or any combination thereof) or in any other form of payment, as determined by the Board and specified in the RSU Award Agreement. At the time of grant, the Board may determine to impose such restrictions or conditions that delay such delivery to a date following the vesting of the RSU Award.

(b) Performance Awards. With respect to any Performance Award, the length of any Performance Period, the Performance Goals to be achieved during the Performance Period, the other terms and conditions of such Award, and the measure of whether and to what degree such Performance Goals have been attained will be determined by the Board.

(c) Other Awards. Other forms of Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair Market Value at the time of grant, subject to compliance with Section 409A) may be granted either alone or in addition to Awards provided for under Section 4 and the preceding provisions of this Section 5. Subject to the provisions of the Plan, the Board will have sole and complete discretion to determine the persons to whom and the time or times at which such Other Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to be granted pursuant to such Other Awards and all other terms and conditions of such Other Awards.

6.	ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.

(a) Capitalization Adjustments. In the event of a Capitalization Adjustment, the Board shall appropriately and proportionately adjust: (i) the class(es) and maximum number of shares of Common Stock subject to the Plan and the maximum number of shares by which the Share Reserve may annually increase pursuant to Section 2(a); (ii) the class(es) and maximum number of shares that may be issued pursuant to the exercise of Incentive Stock Options pursuant to Section 2(b); and (iii) the class(es) and number of securities and exercise price, strike price or purchase price of Common Stock subject to outstanding Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. Notwithstanding the foregoing, no fractional shares or rights for fractional shares of Common Stock shall be created in order to implement any Capitalization Adjustment. The Board shall determine an appropriate equivalent benefit, if any, for any fractional shares or rights to fractional shares that might be created by the adjustments referred to in the preceding provisions of this Section.

(b) Dissolution or Liquidation. Except as otherwise provided in the Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Awards (other than Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the Company’s right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be repurchased or reacquired by the Company notwithstanding the fact that the holder of such Award is providing Continuous Service; provided, however, that the Board may determine to cause some or all Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion.

(c) Corporate Transaction. The following provisions will apply to Awards in the event of a Corporate Transaction, except as set forth in Section 11, unless otherwise provided in the instrument evidencing the Award or any other written agreement between the Company or any Affiliate and the Participant or unless otherwise expressly provided by the Board (as reflected in written Board action) at the time of grant of an Award.

(i) Awards May Be Assumed. In the event of a Corporate Transaction, any surviving or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue any or all Awards outstanding under the Plan or may substitute similar awards for Awards outstanding under the Plan (including but not limited to awards to acquire the same consideration paid to the stockholders of the Company

C-7

pursuant to the Corporate Transaction), and any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to Awards may be assigned by the Company to the successor of the Company (or the successor’s parent company, if any), in connection with such Corporate Transaction. A surviving or acquiring corporation (or its applicable parent) may choose to assume or continue only a portion of an Award or substitute a similar award for only a portion of an Award, or may choose to assume or continue the Awards held by some, but not all Participants. The terms of any assumption, continuation or substitution will be set by the Board.

(ii) Awards Held by Current Participants. In the event of a Corporate Transaction in which the surviving or acquiring corporation (or its parent company) does not assume or continue outstanding Awards or substitute similar awards for such outstanding Awards, then with respect to Awards that have not been assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated prior to the effective time of the Corporate Transaction (referred to as the “Current Participants”), the vesting of such Awards (and, with respect to Options and Stock Appreciation Rights, the time when such Awards may be exercised) will be accelerated in full to a date prior to the effective time of such Corporate Transaction (contingent upon the effectiveness of the Corporate Transaction) that the Board determines (or, if the Board does not determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction). Awards so accelerated will terminate if not exercised (if applicable) at or prior to the effective time of the Corporate Transaction, and any reacquisition or repurchase rights held by the Company with respect to such Awards will lapse (contingent upon the effectiveness of the Corporate Transaction). With respect to the vesting of Performance Awards that (a) will accelerate upon the occurrence of a Corporate Transaction pursuant to this subsection (ii) and (b) have multiple vesting levels depending on the level of performance, unless otherwise provided in the Award Agreement or unless otherwise provided by the Board, the vesting of such Performance Awards will accelerate at 100% of the target level upon the occurrence of a Corporate Transaction in which the Awards are not assumed, continued or substituted for in accordance with Section 6(c)(i). With respect to the vesting of cash-settled Awards that will accelerate upon the occurrence of a Corporate Transaction pursuant to this subsection (ii), such cash payment will be made no later than 30 days following the occurrence of the Corporate Transaction or such later date as required by Section 409A of the Code.

(iii) Awards Held by Persons other than Current Participants. In the event of a Corporate Transaction in which the surviving or acquiring corporation (or its parent company) does not assume or continue such outstanding Awards or substitute similar awards for such outstanding Awards, then with respect to Awards that have not been assumed, continued or substituted and that are held by persons other than Current Participants, such Awards will terminate if not exercised (if applicable) prior to the occurrence of the Corporate Transaction; provided, however, that any reacquisition or repurchase rights held by the Company with respect to such Awards will not terminate and may continue to be exercised notwithstanding the Corporate Transaction.

(iv) Payment for Awards in Lieu of Exercise. Notwithstanding the foregoing, in the event an Award will terminate if not exercised prior to the effective time of a Corporate Transaction, the Board may provide, in its sole discretion, that the holder of such Award may not exercise such Award but will receive a payment, in such form as may be determined by the Board, equal in value, at the effective time, to the excess, if any, of (1) the value of the property the Participant would have received upon the exercise of the Award (including, at the discretion of the Board, any unvested portion of such Award), over (2) any exercise price payable by such holder in connection with such exercise. In the event there is no such excess, the Award may be terminated without consideration.

(d) Appointment of Stockholder Representative. As a condition to the receipt of an Award under this Plan, a Participant will be deemed to have agreed that the Award will be subject to the terms of any agreement governing a Corporate Transaction involving the Company, including, without limitation, a provision for the appointment of a stockholder representative that is authorized to act on the Participant’s behalf with respect to any escrow, indemnities and any contingent consideration.

C-8

(e) No Restriction on Right to Undertake Transactions. The grant of any Award under the Plan and the issuance of shares pursuant to any Award does not affect or restrict in any way the right or power of the Company or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, rights or options to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are superior to or affect the Common Stock or the rights thereof or which are convertible into or exchangeable for Common Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

7.	ADMINISTRATION.

(a) Administration by Board. The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in subsection (c) below.

(b) Powers of Board. The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To determine from time to time (1) which of the persons eligible under the Plan will be granted Awards; (2) when and how each Award will be granted; (3) what type or combination of types of Award will be granted; (4) the provisions of each Award granted (which need not be identical), including the time or times when a person will be permitted to receive an issuance of Common Stock or other payment pursuant to an Award; (5) the number of shares of Common Stock or cash equivalent with respect to which an Award will be granted to each such person; (6) the Fair Market Value applicable to an Award; and (7) the terms of any Performance Award that is not valued in whole or in part by reference to, or otherwise based on, the Common Stock, including the amount of cash payment or other property that may be earned and the timing of payment.

(ii) To construe and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Award Agreement, in a manner and to the extent it deems necessary or expedient to make the Plan or Award fully effective.

(iii) To settle all controversies regarding the Plan and Awards granted under it.

(iv) To accelerate the time at which an Award may first be exercised or the time during which an Award or any part thereof will vest, notwithstanding the provisions in the Award Agreement stating the time at which it may first be exercised or the time during which it will vest.

(v) To prohibit the exercise of any Option, SAR or other exercisable Award during a period of up to 30 days prior to the consummation of any pending stock dividend, stock split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other change affecting the shares of Common Stock or the share price of the Common Stock including any Corporate Transaction, for reasons of administrative convenience.

(vi) To suspend or terminate the Plan at any time. Suspension or termination of the Plan will not Materially Impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant.

(vii) To amend the Plan in any respect the Board deems necessary or advisable; provided, however, that stockholder approval will be required for any amendment to the extent required by Applicable Law. Except as provided above, rights under any Award granted before amendment of the Plan will not be Materially Impaired by any amendment of the Plan unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.

C-9

(viii) To submit any amendment to the Plan for stockholder approval.

(ix) To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided however, that, a Participant’s rights under any Award will not be Materially Impaired by any such amendment unless (1) the Company requests the consent of the affected Participant, and (2) such Participant consents in writing.

(x) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards.

(xi) To adopt such procedures and sub-plans as are necessary or appropriate to permit and facilitate participation in the Plan by, or take advantage of specific tax treatment for Awards granted to, Employees, Directors or Consultants who are foreign nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial modifications to the Plan or any Award Agreement to ensure or facilitate compliance with the laws of the relevant foreign jurisdiction).

(xii) To effect, at any time and from time to time, subject to stockholder approval and subject to the consent of any Participant whose Award is Materially Impaired by such action, (1) the reduction of the exercise price (or strike price) of any outstanding Option or SAR; (2) the cancellation of any outstanding Option or SAR and the grant in substitution therefor of (A) a new Option, SAR, Restricted Stock Award, RSU Award or Other Award, under the Plan or another equity plan of the Company, covering the same or a different number of shares of Common Stock, (B) cash and/or (C) other valuable consideration (as determined by the Board); or (3) any other action that is treated as a repricing under generally accepted accounting principles.

(c) Delegation to Committee.

(i) General. The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration of the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to another Committee or a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. Each Committee may retain the authority to concurrently administer the Plan with Committee or subcommittee to which it has delegated its authority hereunder and may, at any time, revest in such Committee some or all of the powers previously delegated. The Board may retain the authority to concurrently administer the Plan with any Committee and may, at any time, revest in the Board some or all of the powers previously delegated.

(ii) Rule 16b-3 Compliance. To the extent an Award is intended to qualify for the exemption from Section 16(b) of the Exchange Act that is available under Rule 16b-3 of the Exchange Act, the Award will be granted by the Board or a Committee that consists solely of two or more Non-Employee Directors, as determined under Rule 16b-3(b)(3) of the Exchange Act and thereafter any action establishing or modifying the terms of the Award will be approved by the Board or a Committee meeting such requirements to the extent necessary for such exemption to remain available.

(d) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board or any Committee in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

C-10

(e) Delegation to an Officer. The Board or any Committee may delegate to one or more Officers the authority to do one or both of the following (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by Applicable Law, other types of Awards) and, to the extent permitted by Applicable Law, the terms thereof, and (ii) determine the number of shares of Common Stock to be subject to such Awards granted to such Employees; provided, however, that the resolutions or charter adopted by the Board or any Committee evidencing such delegation will specify the total number of shares of Common Stock that may be subject to the Awards granted by such Officer and that such Officer may not grant an Award to himself or herself. Any such Awards will be granted on the applicable form of Award Agreement most recently approved for use by the Board or the Committee, unless otherwise provided in the resolutions approving the delegation authority. Notwithstanding anything to the contrary herein, neither the Board nor any Committee may delegate to an Officer who is acting solely in the capacity of an Officer (and not also as a Director) the authority to determine the Fair Market Value.

8.	TAX WITHHOLDING

(a) Withholding Authorization. As a condition to acceptance of any Award under the Plan, a Participant authorizes withholding from payroll and any other amounts payable to such Participant, and otherwise agrees to make adequate provision for (including), any sums required to satisfy any U.S. federal, state, local and/or foreign tax or social insurance contribution withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise, vesting or settlement of such Award, as applicable. Accordingly, a Participant may not be able to exercise an Award even though the Award is vested, and the Company shall have no obligation to issue shares of Common Stock subject to an Award, unless and until such obligations are satisfied.

(b) Satisfaction of Withholding Obligation. To the extent permitted by the terms of an Award Agreement, the Company may, in its sole discretion, satisfy any U.S. federal, state, local and/or foreign tax or social insurance withholding obligation relating to an Award by any of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock issued or otherwise issuable to the Participant in connection with the Award; (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the Participant; (v) by allowing a Participant to effectuate a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board; or (vi) by such other method as may be set forth in the Award Agreement.

(c) No Obligation to Notify or Minimize Taxes; No Liability to Claims. Except as required by Applicable Law the Company has no duty or obligation to any Participant to advise such holder as to the time or manner of exercising such Award. Furthermore, the Company has no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be exercised. The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award and will not be liable to any holder of an Award for any adverse tax consequences to such holder in connection with an Award. As a condition to accepting an Award under the Plan, each Participant (i) agrees to not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates related to tax liabilities arising from such Award or other Company compensation and (ii) acknowledges that such Participant was advised to consult with their own personal tax, financial and other legal advisors regarding the tax consequences of the Award and has either done so or knowingly and voluntarily declined to do so. Additionally, each Participant acknowledges any Option or SAR granted under the Plan is exempt from Section 409A only if the exercise or strike price is at least equal to the “fair market value” of the Common Stock on the date of grant as determined by the Internal Revenue Service and there is no other impermissible deferral of compensation associated with the Award. Additionally, as a condition to accepting an Option or SAR granted under the Plan, each Participant agrees not make any claim against the Company, or any of its Officers, Directors, Employees or Affiliates in the event that the Internal Revenue Service asserts that such exercise price or strike price is less than the “fair market value” of the Common Stock on the date of grant as subsequently determined by the Internal Revenue Service.

C-11

(d) Withholding Indemnification. As a condition to accepting an Award under the Plan, in the event that the amount of the Company’s and/or its Affiliate’s withholding obligation in connection with such Award was greater than the amount actually withheld by the Company and/or its Affiliates, each Participant agrees to indemnify and hold the Company and/or its Affiliates harmless from any failure by the Company and/or its Affiliates to withhold the proper amount.

9.	MISCELLANEOUS.

(a) Source of Shares. The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise.

(b) Use of Proceeds from Sales of Common Stock. Proceeds from the sale of shares of Common Stock pursuant to Awards will constitute general funds of the Company.

(c) Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action approving the grant contain terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the Award Agreement or related grant documents, the corporate records will control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents.

(d) Stockholder Rights. No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Award unless and until (i) such Participant has satisfied all requirements for exercise of the Award pursuant to its terms, if applicable, and (ii) the issuance of the Common Stock subject to such Award is reflected in the records of the Company.

(e) No Employment or Other Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or affect the right of the Company or an Affiliate to terminate at will and without regard to any future vesting opportunity that a Participant may have with respect to any Award (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state or foreign jurisdiction in which the Company or the Affiliate is incorporated, as the case may be. Further, nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award will constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future compensation or any other term or condition of employment or service or confer any right or benefit under the Award or the Plan unless such right or benefit has specifically accrued under the terms of the Award Agreement and/or Plan.

(f) Change in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of their services for the Company and any Affiliates is reduced (for example, and without limitation, if the Participant is an Employee of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee or takes an extended leave of absence) after the date of grant of any Award to the Participant, the Board may determine, to the extent permitted by Applicable Law, to (i) make a corresponding reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (ii) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended.

C-12

(g) Execution of Additional Documents. As a condition to accepting an Award under the Plan, the Participant agrees to execute any additional documents or instruments necessary or desirable, as determined in the Plan Administrator’s sole discretion, to carry out the purposes or intent of the Award, or facilitate compliance with securities and/or other regulatory requirements, in each case at the Plan Administrator’s request.

(h) Electronic Delivery and Participation. Any reference herein or in an Award Agreement to a “written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet (or other shared electronic medium controlled by the Company to which the Participant has access). By accepting any Award the Participant consents to receive documents by electronic delivery and to participate in the Plan through any on-line electronic system established and maintained by the Plan Administrator or another third party selected by the Plan Administrator. The form of delivery of any Common Stock (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the Company.

(i) Clawback/Recovery. All Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Law and any clawback policy that the Company otherwise adopts, to the extent applicable and permissible under Applicable Law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate, including but not limited to a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. No recovery of compensation under such a clawback policy will be an event giving rise to a Participant’s right to voluntarily terminate employment upon a “resignation for good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company.

(j) Securities Law Compliance. A Participant will not be issued any shares in respect of an Award unless either (i) the shares are registered under the Securities Act; or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Each Award also must comply with other Applicable Law governing the Award, and a Participant will not receive such shares if the Company determines that such receipt would not be in material compliance with Applicable Law.

(k) Transfer or Assignment of Awards; Issued Shares. Except as expressly provided in the Plan or the form of Award Agreement, Awards granted under the Plan may not be transferred or assigned by the Participant. After the vested shares subject to an Award have been issued, or in the case of Restricted Stock and similar awards, after the issued shares have vested, the holder of such shares is free to assign, hypothecate, donate, encumber or otherwise dispose of any interest in such shares provided that any such actions are in compliance with the provisions herein, the terms of the Trading Policy and Applicable Law.

(l) Effect on Other Employee Benefit Plans. The value of any Award granted under the Plan, as determined upon grant, vesting or settlement, shall not be included as compensation, earnings, salaries, or other similar terms used when calculating any Participant’s benefits under any employee benefit plan sponsored by the Company or any Affiliate, except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Affiliate’s employee benefit plans.

(m) Deferrals. To the extent permitted by Applicable Law, the Board, in its sole discretion, may determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may also establish programs and procedures for deferral elections to be made by Participants. Deferrals will be made in accordance with the requirements of Section 409A.

(n) Section 409A. Unless otherwise expressly provided for in an Award Agreement, the Plan and Award Agreements will be interpreted to the greatest extent possible in a manner that makes the Plan and the Awards

C-13

granted hereunder exempt from Section 409A, and, to the extent not so exempt, in compliance with the requirements of Section 409A. If the Board determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference into the Award Agreement. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if the shares of Common Stock are publicly traded, and if a Participant holding an Award that constitutes “deferred compensation” under Section 409A is a “specified employee” for purposes of Section 409A, no distribution or payment of any amount that is due because of a “separation from service” (as defined in Section 409A without regard to alternative definitions thereunder) will be issued or paid before the date that is six months and one day following the date of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death, unless such distribution or payment can be made in a manner that complies with Section 409A, and any amounts so deferred will be paid in a lump sum on the day after such six month period elapses, with the balance paid thereafter on the original schedule.

(o) Choice of Law. This Plan and any controversy arising out of or relating to this Plan shall be governed by, and construed in accordance with, the internal laws of the State of Delaware, without regard to conflict of law principles that would result in any application of any law other than the law of the State of Delaware.

10.

COVENANTS OF THE COMPANY.

The Company will seek to obtain from each regulatory commission or agency, as may be deemed to be necessary, having jurisdiction over the Plan such authority as may be required to grant Awards and to issue and sell shares of Common Stock upon exercise or vesting of the Awards; provided, however, that this undertaking will not require the Company to register under the Securities Act the Plan, any Award or any Common Stock issued or issuable pursuant to any such Award. If, after reasonable efforts and at a reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary or advisable for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock upon exercise or vesting of such Awards unless and until such authority is obtained. A Participant is not eligible for the grant of an Award or the subsequent issuance of Common Stock pursuant to the Award if such grant or issuance would be in violation of any Applicable Law.

11.

ADDITIONAL RULES FOR AWARDS SUBJECT TO SECTION 409A.

(a) Application. Unless the provisions of this Section of the Plan are expressly superseded by the provisions in the form of Award Agreement, the provisions of this Section shall apply and shall supersede anything to the contrary set forth in the Award Agreement for a Non-Exempt Award.

(b) Non-Exempt Awards Subject to Non-Exempt Severance Arrangements. To the extent a Non-Exempt Award is subject to Section 409A due to application of a Non-Exempt Severance Arrangement, the following provisions of this subsection (b) apply.

(i) If the Non-Exempt Award vests in the ordinary course during the Participant’s Continuous Service in accordance with the vesting schedule set forth in the Award Agreement, and does not accelerate vesting under the terms of a Non-Exempt Severance Arrangement, in no event will the shares be issued in respect of such Non-Exempt Award any later than the later of: (i) December 31^st of the calendar year that includes the applicable vesting date, or (ii) the 60^th day that follows the applicable vesting date.

(ii) If vesting of the Non-Exempt Award accelerates under the terms of a Non-Exempt Severance Arrangement in connection with the Participant’s Separation from Service, and such vesting acceleration provisions were in effect as of the date of grant of the Non-Exempt Award and, therefore, are part of the terms of

C-14

such Non-Exempt Award as of the date of grant, then the shares will be earlier issued in settlement of such Non-Exempt Award upon the Participant’s Separation from Service in accordance with the terms of the Non-Exempt Severance Arrangement, but in no event later than the 60^th day that follows the date of the Participant’s Separation from Service. However, if at the time the shares would otherwise be issued the Participant is subject to the distribution limitations contained in Section 409A applicable to “specified employees,” as defined in Section 409A(a)(2)(B)(i) of the Code, such shares shall not be issued before the date that is six months following the date of such Participant’s Separation from Service, or, if earlier, the date of the Participant’s death that occurs within such six month period.

(iii) If vesting of a Non-Exempt Award accelerates under the terms of a Non-Exempt Severance Arrangement in connection with a Participant’s Separation from Service, and such vesting acceleration provisions were not in effect as of the date of grant of the Non-Exempt Award and, therefore, are not a part of the terms of such Non-Exempt Award on the date of grant, then such acceleration of vesting of the Non-Exempt Award shall not accelerate the issuance date of the shares, but the shares shall instead be issued on the same schedule as set forth in the Grant Notice as if they had vested in the ordinary course during the Participant’s Continuous Service, notwithstanding the vesting acceleration of the Non-Exempt Award. Such issuance schedule is intended to satisfy the requirements of payment on a specified date or pursuant to a fixed schedule, as provided under Treasury Regulations Section 1.409A-3(a)(4).

(c) Treatment of Non-Exempt Awards Upon a Corporate Transaction for Employees and Consultants. The provisions of this subsection (c) shall apply and shall supersede anything to the contrary set forth in the Plan with respect to the permitted treatment of any Non-Exempt Award in connection with a Corporate Transaction if the Participant was either an Employee or Consultant upon the applicable date of grant of the Non-Exempt Award.

(i) Vested Non-Exempt Awards. The following provisions shall apply to any Vested Non-Exempt Award in connection with a Corporate Transaction:

(1) If the Corporate Transaction is also a Section 409A Change in Control then the Acquiring Entity may not assume, continue or substitute the Vested Non-Exempt Award. Upon the Section 409A Change in Control the settlement of the Vested Non-Exempt Award will automatically be accelerated and the shares will be immediately issued in respect of the Vested Non-Exempt Award. Alternatively, the Company may instead provide that the Participant will receive a cash settlement equal to the Fair Market Value of the shares that would otherwise be issued to the Participant upon the Section 409A Change in Control.

(2) If the Corporate Transaction is not also a Section 409A Change in Control, then the Acquiring Entity must either assume, continue or substitute each Vested Non-Exempt Award. The shares to be issued in respect of the Vested Non-Exempt Award shall be issued to the Participant by the Acquiring Entity on the same schedule that the shares would have been issued to the Participant if the Corporate Transaction had not occurred. In the Acquiring Entity’s discretion, in lieu of an issuance of shares, the Acquiring Entity may instead substitute a cash payment on each applicable issuance date, equal to the Fair Market Value of the shares that would otherwise be issued to the Participant on such issuance dates, with the determination of the Fair Market Value of the shares made on the date of the Corporate Transaction.

(ii) Unvested Non-Exempt Awards. The following provisions shall apply to any Unvested Non-Exempt Award unless otherwise determined by the Board pursuant to subsection (e) of this Section.

(1) In the event of a Corporate Transaction, the Acquiring Entity shall assume, continue or substitute any Unvested Non-Exempt Award. Unless otherwise determined by the Board, any Unvested Non-Exempt Award will remain subject to the same vesting and forfeiture restrictions that were applicable to the Award prior to the Corporate Transaction. The shares to be issued in respect of any Unvested Non-Exempt Award shall be issued to the Participant by the Acquiring Entity on the same schedule that the shares would have

C-15

been issued to the Participant if the Corporate Transaction had not occurred. In the Acquiring Entity’s discretion, in lieu of an issuance of shares, the Acquiring Entity may instead substitute a cash payment on each applicable issuance date, equal to the Fair Market Value of the shares that would otherwise be issued to the Participant on such issuance dates, with the determination of Fair Market Value of the shares made on the date of the Corporate Transaction.

(2) If the Acquiring Entity will not assume, substitute or continue any Unvested Non-Exempt Award in connection with a Corporate Transaction, then such Award shall automatically terminate and be forfeited upon the Corporate Transaction with no consideration payable to any Participant in respect of such forfeited Unvested Non-Exempt Award. Notwithstanding the foregoing, to the extent permitted and in compliance with the requirements of Section 409A, the Board may in its discretion determine to elect to accelerate the vesting and settlement of the Unvested Non-Exempt Award upon the Corporate Transaction, or instead substitute a cash payment equal to the Fair Market Value of such shares that would otherwise be issued to the Participant, as further provided in subsection (e)(ii) below. In the absence of such discretionary election by the Board, any Unvested Non-Exempt Award shall be forfeited without payment of any consideration to the affected Participants if the Acquiring Entity will not assume, substitute or continue the Unvested Non-Exempt Awards in connection with the Corporate Transaction.

(3) The foregoing treatment shall apply with respect to all Unvested Non-Exempt Awards upon any Corporate Transaction, and regardless of whether or not such Corporate Transaction is also a Section 409A Change in Control.

(d) Treatment of Non-Exempt Awards Upon a Corporate Transaction for Non-Employee Directors. The following provisions of this subsection (d) shall apply and shall supersede anything to the contrary that may be set forth in the Plan with respect to the permitted treatment of a Non-Exempt Director Award in connection with a Corporate Transaction.

(i) If the Corporate Transaction is also a Section 409A Change in Control then the Acquiring Entity may not assume, continue or substitute the Non-Exempt Director Award. Upon the Section 409A Change in Control the vesting and settlement of any Non-Exempt Director Award will automatically be accelerated and the shares will be immediately issued to the Participant in respect of the Non-Exempt Director Award. Alternatively, the Company may provide that the Participant will instead receive a cash settlement equal to the Fair Market Value of the shares that would otherwise be issued to the Participant upon the Section 409A Change in Control pursuant to the preceding provision.

(ii) If the Corporate Transaction is not also a Section 409A Change in Control, then the Acquiring Entity must either assume, continue or substitute the Non-Exempt Director Award. Unless otherwise determined by the Board, the Non-Exempt Director Award will remain subject to the same vesting and forfeiture restrictions that were applicable to the Award prior to the Corporate Transaction. The shares to be issued in respect of the Non-Exempt Director Award shall be issued to the Participant by the Acquiring Entity on the same schedule that the shares would have been issued to the Participant if the Corporate Transaction had not occurred. In the Acquiring Entity’s discretion, in lieu of an issuance of shares, the Acquiring Entity may instead substitute a cash payment on each applicable issuance date, equal to the Fair Market Value of the shares that would otherwise be issued to the Participant on such issuance dates, with the determination of Fair Market Value made on the date of the Corporate Transaction.

(e) If the RSU Award is a Non-Exempt Award, then the provisions in this Section 11(e) shall apply and supersede anything to the contrary that may be set forth in the Plan or the Award Agreement with respect to the permitted treatment of such Non-Exempt Award:

(i) Any exercise by the Board of discretion to accelerate the vesting of a Non-Exempt Award shall not result in any acceleration of the scheduled issuance dates for the shares in respect of the Non-Exempt Award unless earlier issuance of the shares upon the applicable vesting dates would be in compliance with the requirements of Section 409A.

C-16

(ii) The Company explicitly reserves the right to earlier settle any Non-Exempt Award to the extent permitted and in compliance with the requirements of Section 409A, including pursuant to any of the exemptions available in Treasury Regulations Section 1.409A-3(j)(4)(ix).

(iii) To the extent the terms of any Non-Exempt Award provide that it will be settled upon a Change in Control or Corporate Transaction, to the extent it is required for compliance with the requirements of Section 409A, the Change in Control or Corporate Transaction event triggering settlement must also constitute a Section 409A Change in Control. To the extent the terms of a Non-Exempt Award provides that it will be settled upon a termination of employment or termination of Continuous Service, to the extent it is required for compliance with the requirements of Section 409A, the termination event triggering settlement must also constitute a Separation From Service. However, if at the time the shares would otherwise be issued to a Participant in connection with a “separation from service” such Participant is subject to the distribution limitations contained in Section 409A applicable to “specified employees,” as defined in Section 409A(a)(2)(B)(i) of the Code, such shares shall not be issued before the date that is six months following the date of the Participant’s Separation From Service, or, if earlier, the date of the Participant’s death that occurs within such six month period.

(iv) The provisions in this subsection (e) for delivery of the shares in respect of the settlement of an RSU Award that is a Non-Exempt Award are intended to comply with the requirements of Section 409A so that the delivery of the shares to the Participant in respect of such Non-Exempt Award will not trigger the additional tax imposed under Section 409A, and any ambiguities herein will be so interpreted.

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur (A) on account of the acquisition of securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities, or (C) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur;

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than 50% of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction;

(iii) there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than 50% of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such sale, lease, license or other disposition; or

(iv) individuals who, on the date the Plan is adopted by the Board, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall, for purposes of this Plan, be considered as a member of the Incumbent Board.

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Change in Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, and (B) the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply.

However, service solely as a Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person.

(s) “Continuous Service” means that the Participant’s service with the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in the Entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service; provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. For example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of Continuous Service. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, a leave of absence will be treated as Continuous Service for purposes of vesting in an Award only to such extent as may be provided in the Company’s leave of absence policy, in the written terms of any leave of absence agreement or policy applicable to the Participant, or as otherwise required by law. In addition, to the extent required for exemption from or compliance with Section 409A, the determination of whether there has been a termination of Continuous Service will be made, and such term will be construed, in a manner that is consistent with the definition of “separation from service” as defined under Treasury Regulation Section 1.409A-1(h) (without regard to any alternative definition thereunder).

(t) “Corporate Transaction” means the consummation, in a single transaction or in a series of related transactions, of any one or more of the following events:

(iii) a merger, consolidation or similar transaction following which the Company is not the surviving corporation; or

C-20

(iv) a merger, consolidation or similar transaction following which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger, consolidation or similar transaction are converted or exchanged by virtue of the merger, consolidation or similar transaction into other property, whether in the form of securities, cash or otherwise.

Notwithstanding the foregoing or any other provision of this Plan, (A) the term Corporate Transaction shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company, (B) the definition of Corporate Transaction (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Awards subject to such agreement; provided, however, that if no definition of Corporate Transaction or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply, and (C) with respect to any nonqualified deferred compensation that becomes payable on account of the Corporate Transaction, the transaction or event described in clause (i), (ii), (iii), or (iv) also constitutes a Section 409A Change in Control if required in order for the payment not to violate Section 409A of the Code.

(v) “determine” or “determined” means as determined by the Board or the Committee (or its designee) in its sole discretion.

(z) “Employer” means the Company or the Affiliate of the Company that employs the Participant.

C-21

(dd) “Fair Market Value” means, as of any date, unless otherwise determined by the Board, the value of the Common Stock (as determined on a per share or aggregate basis, as applicable) determined as follows:

(i) If the Common Stock is listed on any established stock exchange or traded on any established market, the Fair Market Value will be the closing sales price for such stock as quoted on such exchange or market (or the exchange or market with the greatest volume of trading in the Common Stock) on the date of determination, as reported in a source the Board deems reliable.

(ii) If there is no closing sales price for the Common Stock on the date of determination, then the Fair Market Value will be the closing selling price on the last preceding date for which such quotation exists.

(iii) In the absence of such markets for the Common Stock, or if otherwise determined by the Board, the Fair Market Value will be determined by the Board in good faith and in a manner that complies with Sections 409A and 422 of the Code.

A Participant’s rights under an Award will not be deemed to have been Materially Impaired by any such amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the Participant’s rights. For example, the following types of amendments to the terms of an Award do not Materially Impair the Participant’s rights under the Award: (i) imposition of reasonable restrictions on the minimum number of shares subject to an Option or SAR that may be exercised; (ii) to maintain the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (iii) to change the terms of an Incentive Stock Option in a manner that disqualifies, impairs or otherwise affects the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code; (iv) to clarify the manner of exemption from, or to bring the Award into compliance with or qualify it for an exemption from, Section 409A; or (v) to comply with other Applicable Laws.

(ii) “Non-Employee Director” means a Director who either (i) is not a current employee or officer of the Company or an Affiliate, does not receive compensation, either directly or indirectly, from the Company or an Affiliate for services rendered as a consultant or in any capacity other than as a Director (except for an amount as to which disclosure would not be required under Item 404(a) of Regulation S-K promulgated pursuant to the Securities Act (“Regulation S-K”)), does not possess an interest in any other transaction for which disclosure would be required under Item 404(a) of Regulation S-K, and is not engaged in a business relationship for which disclosure would be required pursuant to Item 404(b) of Regulation S-K; or (ii) is otherwise considered a “non-employee director” for purposes of Rule 16b-3.

SENTI BIOSCIENCES INC.

2022 EMPLOYEE STOCK PURCHASE PLAN

ADOPTED BY THE BOARD OF DIRECTORS: [ ] 2022

APPROVED BY THE STOCKHOLDERS: [ ], 2022

1.	GENERAL; PURPOSE.

(a) The Plan provides a means by which Eligible Employees of the Company and certain designated Related Corporations may be given an opportunity to purchase shares of Common Stock. The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees under an Employee Stock Purchase Plan.

(b) The Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the services of new Employees and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Related Corporations.

2.	ADMINISTRATION.

(a) The Board will administer the Plan unless and until the Board delegates administration of the Plan to a Committee or Committees, as provided in Section 2(c).

(b) The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan:

(i) To determine how and when Purchase Rights will be granted and the provisions of each Offering (which need not be identical).

(ii) To designate from time to time which Related Corporations of the Company will be eligible to participate in the Plan.

(iii) To construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it deems necessary or expedient to make the Plan fully effective.

(iv) To settle all controversies regarding the Plan and Purchase Rights granted under the Plan.

(v) To suspend or terminate the Plan at any time as provided in Section 12.

(vi) To amend the Plan at any time as provided in Section 12.

(vii) Generally, to exercise such powers and to perform such acts as it deems necessary or expedient to promote the best interests of the Company and its Related Corporations and to carry out the intent that the Plan be treated as an Employee Stock Purchase Plan.

(viii) To adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Employees who are foreign nationals or employed outside the United States.

(c) The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If administration is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references to the Board in this Plan and in any applicable Offering Document will thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the

D-1

Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan.

(d) All determinations, interpretations and constructions made by the Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons.

3.	SHARES OF COMMON STOCK SUBJECT TO THE PLAN.

(a) Subject to the provisions of Section 11(a) relating to Capitalization Adjustments, the maximum number of shares of Common Stock that may be issued under the Plan will not exceed 592,584 shares of Common Stock, plus the number of shares of Common Stock that are automatically added on January 1st of each year for a period of up to ten years, commencing on January 1, 2023 and ending on (and including) January 1, 2032, in an amount equal to the lesser of (i) one percent (1%) of the total number of shares of Common Stock outstanding on December 31 of the preceding calendar year, and (ii) 1,000,000 shares of Common Stock. Notwithstanding the foregoing, the Board may act prior to the first day of any calendar year to provide that there will be no January 1st increase in the share reserve for such calendar year or that the increase in the share reserve for such calendar year will be a lesser number of shares of Common Stock than would otherwise occur pursuant to the preceding sentence.

(b) If any Purchase Right granted under the Plan terminates without having been exercised in full, the shares of Common Stock not purchased under such Purchase Right will again become available for issuance under the Plan.

(c) The stock purchasable under the Plan will be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market.

4.	GRANT OF PURCHASE RIGHTS; OFFERING.

(a) The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees under an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain such terms and conditions as the Board will deem appropriate, and will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 8, inclusive.

(b) If a Participant has more than one Purchase Right outstanding under the Plan, unless such Participant otherwise indicates in forms delivered to the Company: (i) each form will apply to all of the Participant’s Purchase Rights under the Plan, and (ii) a Purchase Right with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted Purchase Right if different Purchase Rights have identical exercise prices) will be exercised.

(c) The Board will have the discretion to structure an Offering so that if the Fair Market Value of a share of Common Stock on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a share of Common Stock on the Offering Date for that Offering, then (i) that Offering

D-2

will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first Trading Day of such new Purchase Period.

5.	ELIGIBILITY.

(a) Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance with Section 2(b), to Employees of a Related Corporation. Except as provided in Section 5(b), an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the Employee has been in the employ of the Company or the Related Corporation, as the case may be, for such continuous period preceding such Offering Date as the Board may require, but in no event will the required period of continuous employment be equal to or greater than two years. In addition, the Board may provide that no Employee will be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such Employee’s customary employment with the Company or the Related Corporation is more than 20 hours per week and more than five months per calendar year or such other criteria as the Board may determine consistent with Section 423 of the Code.

(b) The Board may provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs thereafter, receive a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right will have the same characteristics as any Purchase Rights originally granted under that Offering, as described herein, except that:

(i) the date on which such Purchase Right is granted will be the “Offering Date” of such Purchase Right for all purposes, including determination of the exercise price of such Purchase Right;

(ii) the period of the Offering with respect to such Purchase Right will begin on its Offering Date and end coincident with the end of such Offering; and

(iii) the Board may provide that if such person first becomes an Eligible Employee within a specified period of time before the end of the Offering, the individual will not receive any Purchase Right under that Offering.

(c) No Employee will be eligible for the grant of any Purchase Rights if, immediately after any such Purchase Rights are granted, such Employee owns stock possessing five percent or more of the total combined voting power or value of all classes of stock of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of Section 424(d) of the Code will apply in determining the stock ownership of any Employee, and stock which such Employee may purchase under all outstanding Purchase Rights and options will be treated as stock owned by such Employee.

(d) As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights only if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations, do not permit such Eligible Employee’s rights to purchase stock of the Company or any Related Corporation to accrue at a rate which, when aggregated, exceeds $25,000 of Fair Market Value of such stock (determined at the time such rights are granted, and which, with respect to the Plan, will be determined as of their respective Offering Dates) for each calendar year in which such rights are outstanding at any time.

(e) Officers of the Company and any designated Related Corporation, if they are otherwise Eligible Employees, will be eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code will not be eligible to participate.

D-3

6.	PURCHASE RIGHTS; PURCHASE PRICE.

(a) On each Offering Date, each Eligible Employee, pursuant to an Offering made under the Plan, will be granted a Purchase Right to purchase up to that number of shares of Common Stock purchasable either with a percentage of earnings (as such concept is defined in the Offering Document) or with a maximum dollar amount, as designated by the Board, during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated in the Offering, which date will be no later than the end of the Offering.

(b) The Board will establish one or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will be exercised and shares of Common Stock will be purchased in accordance with such Offering.

(c) In connection with each Offering made under the Plan, the Board may specify (i) a maximum number of shares of Common Stock that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants pursuant to such Offering and/or (iii) a maximum aggregate number of shares of Common Stock that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of shares of Common Stock issuable upon exercise of Purchase Rights granted under the Offering would exceed any such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation of the shares of Common Stock available will be made in as nearly a uniform manner as will be practicable and equitable.

(d) The purchase price of shares of Common Stock acquired pursuant to Purchase Rights will be not less than the lesser of:

(i) an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the Offering Date; or

(ii) an amount equal to 85% of the Fair Market Value of the shares of Common Stock on the applicable Purchase Date.

7.	PARTICIPATION; WITHDRAWAL; TERMINATION.

(a) An Eligible Employee may elect to participate in an Offering and authorize payroll deductions as the means of making Contributions by completing and delivering to the Company, within the time specified in the Offering, an enrollment form provided by the Company. The enrollment form will specify the amount of Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the Company except where applicable law requires that Contributions be deposited with a third party. If permitted in the Offering, a Participant may begin such Contributions with the first practicable payroll occurring on or after the Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering). If permitted in the Offering, a Participant may thereafter reduce (including to zero) or increase the Participant’s Contributions. If specifically provided in the Offering, in addition to or instead of making Contributions by payroll deductions, a Participant may make Contributions through the payment by cash or check prior to a Purchase Date.

(b) During an Offering, a Participant may cease making Contributions and withdraw from the Offering by delivering to the Company a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. Upon such withdrawal, such Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute as soon as practicable to such Participant all of the Participant’s accumulated but unused Contributions and such Participant’s Purchase Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering will have no effect upon the Participant’s eligibility to participate in any other Offerings under the Plan, but such Participant will be required to deliver a new enrollment form to participate in subsequent Offerings.

D-4

(c) Unless otherwise required by applicable law, Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Employee for any reason or for no reason (subject to any post-employment participation period required by law) or (ii) is otherwise no longer eligible to participate. The Company will distribute to such individual as soon as practicable all of the individual’s accumulated but unused Contributions.

(d) During a Participant’s lifetime, Purchase Rights will be exercisable only by such Participant. Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 10.

(e) Unless otherwise specified in the Offering or required by applicable law, the Company will have no obligation to pay interest on Contributions.

8.	EXERCISE OF PURCHASE RIGHTS.

(a) On each Purchase Date, each Participant’s accumulated Contributions will be applied to the purchase of shares of Common Stock, up to the maximum number of shares of Common Stock permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares will be issued unless specifically provided for in the Offering.

(b) Unless otherwise provided in the Offering, if any amount of accumulated Contributions remains in a Participant’s account after the purchase of shares of Common Stock and such remaining amount is less than the amount required to purchase one share of Common Stock on the final Purchase Date of an Offering, then such remaining amount will be held in such Participant’s account for the purchase of shares of Common Stock under the next Offering under the Plan, unless such Participant withdraws from or is not eligible to participate in such next Offering, in which case such amount will be distributed to such Participant after the final Purchase Date without interest (unless the payment of interest is otherwise required by applicable law). If the amount of Contributions remaining in a Participant’s account after the purchase of shares of Common Stock is at least equal to the amount required to purchase one (1) whole share of Common Stock on the final Purchase Date of an Offering, then such remaining amount will be distributed in full to such Participant after the final Purchase Date of such Offering without interest.

(c) No Purchase Rights may be exercised to any extent unless the shares of Common Stock to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable U.S. federal and state, foreign and other securities, exchange control and other laws applicable to the Plan. If on a Purchase Date the shares of Common Stock are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the Purchase Date will be delayed until the shares of Common Stock are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will in no event be more than 6 months from the Offering Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the shares of Common Stock are not registered and the Plan is not in material compliance with all applicable laws, no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed to the Participants without interest.

9.	COVENANTS OF THE COMPANY.

The Company will seek to obtain from each U.S. federal or state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Purchase Rights and issue and sell shares of Common Stock thereunder unless the Company determines, in its sole discretion, that doing so would cause the Company to incur costs that are unreasonable. If, after commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase Rights or the lawful issuance and sale of Common Stock under the Plan, and at a commercially reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights and/or to issue and sell Common Stock upon exercise of such Purchase Rights.

D-5

10.

DESIGNATION OF BENEFICIARY.

(a) The Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who will receive any shares of Common Stock and/or Contributions from the Participant’s account under the Plan if the Participant dies before such shares and/or Contributions are delivered to the Participant. The Company may, but is not obligated to, permit the Participant to change such designation of beneficiary. Any such designation and/or change must be on a form approved by the Company.

(b) If a Participant dies, and in the absence of a valid beneficiary designation, the Company will deliver any shares of Common Stock and/or Contributions to the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such shares of Common Stock and/or Contributions without interest (unless the payment of interest is otherwise required by applicable law) to the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

11.

ADJUSTMENTS UPON CHANGES IN COMMON STOCK; CORPORATE TRANSACTIONS.

(a) In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is to increase automatically each year pursuant to Section 3(a), (iii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and number of securities that are the subject of the purchase limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding and conclusive.

(b) In the event of a Corporate Transaction, then: (i) any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same consideration paid to the stockholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not substitute similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase shares of Common Stock within ten business days prior to the Corporate Transaction under the outstanding Purchase Rights, and the Purchase Rights will terminate immediately after such purchase.

12.

AMENDMENT, TERMINATION OR SUSPENSION OF THE PLAN.

(a) The Board may amend the Plan at any time in any respect the Board deems necessary or advisable. However, except as provided in Section 11(a) relating to Capitalization Adjustments, stockholder approval will be required for any amendment of the Plan for which stockholder approval is required by applicable law or listing requirements.

(b) The Board may suspend or terminate the Plan at any time. No Purchase Rights may be granted under the Plan while the Plan is suspended or after it is terminated.

(c) Any benefits, privileges, entitlements and obligations under any outstanding Purchase Rights granted before an amendment, suspension or termination of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with the consent of the person to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws, listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and the regulations and other interpretive guidance issued thereunder relating to Employee Stock Purchase Plans) including without limitation any such regulations or other guidance that may be issued or amended after the date the Plan is adopted by the Board, or (iii) as necessary to obtain or maintain favorable tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase Rights without a Participant’s consent if such amendment is necessary to ensure that the Purchase Right and/or the Plan complies with the requirements of Section 423 of the Code.

D-6

Notwithstanding anything in the Plan or any Offering Document to the contrary, the Board will be entitled to: (i) establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars; (ii) permit Contributions in excess of the amount designated by a Participant in order to adjust for mistakes in the Company’s processing of properly completed Contribution elections; (iii) establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Contributions; (iv) amend any outstanding Purchase Rights or clarify any ambiguities regarding the terms of any Offering to enable the Purchase Rights to qualify under and/or comply with Section 423 of the Code; and (v) establish other limitations or procedures as the Board determines in its sole discretion advisable that are consistent with the Plan. The actions of the Board pursuant to this paragraph will not be considered to alter or impair any Purchase Rights granted under an Offering as they are part of the initial terms of each Offering and the Purchase Rights granted under each Offering.

13.

EFFECTIVE DATE OF PLAN.

The Plan will become effective immediately prior to and contingent upon the Closing Date. No Purchase Rights will be exercised unless and until the Plan has been approved by the stockholders of the Company, which approval must be within 12 months before or after the date the Plan is adopted (or if required under Section 12(a) above, materially amended) by the Board.

14.

MISCELLANEOUS PROVISIONS.

(a) Proceeds from the sale of shares of Common Stock pursuant to Purchase Rights will constitute general funds of the Company.

(b) A Participant will not be deemed to be the holder of, or to have any of the rights of a holder with respect to, shares of Common Stock subject to Purchase Rights unless and until the Participant’s shares of Common Stock acquired upon exercise of Purchase Rights are recorded in the books of the Company (or its transfer agent).

(b) The Plan and Offering do not constitute an employment contract. Nothing in the Plan or in the Offering will in any way alter the at will nature of a Participant’s employment or be deemed to create in any way whatsoever any obligation on the part of any Participant to continue in the employ of the Company or a Related Corporation, or on the part of the Company or a Related Corporation to continue the employment of a Participant.

(c) The provisions of the Plan will be governed by the laws of the State of Delaware without resort to that state’s conflict of laws rules.
