SUBJECT TO COMPLETION, DATED NOVEMBER 19, 2025

PRELIMINARY PROSPECTUS

Up to 27,885,987 Shares of Common Stock

Streamex Corp.

This prospectus relates to the offer and sale, from time to time, by the selling security holders identified in this prospectus of up to 27,885,987 shares of the common stock of Streamex Corp. (f/k/a BioSig Technologies, Inc.), a Delaware corporation (the “Company,” “we,” “our,” or “us”), par value $0.001 per share (“Common Stock”), comprising:

See “Selling Shareholders” for additional information regarding the Selling Shareholders.

In addition to the First Secured Convertible Debenture and the Second Secured Convertible Debenture, the Secured Convertible Debenture Purchase Agreement, dated July 7, 2025, (the “DPA”) as amended, provides that we may be able to issue additional secured convertible debentures in an aggregate principal amount of up to $50,000,000 upon mutual agreement of the parties. We may not have access to the additional $50 million principal amount otherwise available under the DPA due to the factors discussed in this prospectus, or if this registration statement does not become effective. Please see “Selling Shareholders—Material Relationships with Selling Shareholders—Share Purchase Agreement” for more information regarding the Share Purchase Agreement, as amended, “Selling Shareholders—Material Relationships with Selling Shareholders—DPA” for more information regarding the DPA.

We are not selling any shares of our shares of Common Stock pursuant to this prospectus, and we will not receive any of the proceeds from the sale of shares of our Common Stock by the Selling Shareholders. We will bear all costs, expenses and fees in connection with the registration of the Common Stock. The Selling Shareholders will bear all commissions and discounts, if any, attributable to their respective sales of Common Stock. We are registering the Debenture Shares for resale pursuant to that certain Registration Rights Agreement dated as of November 4, 2025, by and between us and Yorkville, and the Merger Shares for resale pursuant to the Share Purchase Agreement. Our registration of the securities covered by this prospectus does not mean that the Selling Shareholders will offer or sell any of the shares being registered in this prospectus. See the section of this prospectus entitled “Selling Shareholders” for more information. However, we may receive proceeds if we issue the Second Secured Convertible Debenture.

The Selling Shareholders may offer all or part of the shares registered hereby for resale from time to time through public or private transactions, at either prevailing market prices or at privately negotiated prices. Our registration of the Common Stock covered by this prospectus does not mean that the Selling Shareholders will offer or sell any of the Common Stock. With regard only to the shares of Common Stock the Selling Shareholders sell on their own behalf, such Selling Shareholders may be deemed an “underwriter” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). The Selling Shareholders may offer and sell the securities covered by this prospectus in a number of different ways and at varying prices. If any underwriters, dealers or agents are involved in the sale of any of the securities, their names and any applicable purchase price, fee, commission or discount arrangement between or among them will be set forth, or will be calculable from the information set forth, in any applicable prospectus supplement. See the sections of this prospectus entitled “About this Prospectus” and “Plan of Distribution” for more information. No securities may be sold without delivery of this prospectus and any applicable prospectus supplement describing the method and terms of the offering of such securities. You should carefully read this prospectus and any applicable prospectus supplement before you invest in our securities.

The sale of all or a portion of the securities being offered in this prospectus could result in a significant decline in the public trading price of our securities. Despite such a decline in the public trading price, some of the Selling Shareholders may still experience a positive rate of return on the securities they purchased due to the price at which such Selling Shareholders initially purchased the securities.

We are a “smaller reporting company” as defined in Section 2(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are subject to reduced public company reporting requirements. This prospectus complies with the requirements that apply to an issuer that is a smaller reporting company.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol “STEX.” On November 17, 2025, the last reported sales price of the Common Stock was $3.73 per share.

Investing in our securities involves a high degree of risk. These risks are discussed in this prospectus under “Risk Factors” beginning on page 6 and in the documents incorporated by reference in this prospectus.

Neither the U.S. Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The RESALE offering

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should consider carefully the specific risk factors discussed below, together with all of the other information contained or incorporated by reference in this prospectus or any prospectus supplement. You should also consider the risks, uncertainties and assumptions discussed under Part I, Item 1A, “Risk Factors,” in our most recent Annual Report on Form 10-K and any updates in Part II, Item 1A, “Risk Factors,” in our subsequent Quarterly Reports on Form 10-Q, and under the caption “Risk Factors” in Exhibit 99.1 to our Current Report on Form 8-K/A filed with the SEC on July 21, 2025, which are incorporated herein by reference, as updated or superseded by the risks and uncertainties described under similar headings in the other documents that are filed after the date hereof and incorporated by reference into this prospectus. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, business prospects, financial condition or results of operations could be seriously harmed. This could cause the trading price of our Common Stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section above entitled “Cautionary Statement Regarding Forward-Looking Statements.”

Additional Risks Related to Our Business and Industry

Streamex has a limited operating history, and we have incurred significant losses since inception.

Streamex was incorporated on April 5, 2024, and has a limited operating history upon which investors may evaluate its business, prospects, and performance. We are therefore subject to all of the risks and uncertainties typically associated with the development of a new business, including the need to attract customers, develop and commercialize Streamex’s software products and services, and achieve market acceptance.

The Company and its subsidiaries have incurred significant operating losses since inception. For the period from incorporation to December 31, 2024, the consolidated Company incurred a net loss of approximately $255.35 million. The Company as a whole has incurred significant operating losses. For the years ended December 31, 2024 and 2023, we incurred net losses of approximately $10.5 million and $29.0 million, respectively. For the nine months ended September 30, 2025 and 2024, we incurred a comprehensive loss attributable to the consolidated Company of approximately $38.8 million and $9.2 million, respectively. As of September 30, 2025, we have an accumulated deficit of approximately $294.1 million. 

The independent registered public accounting firms that audited our financial statements and the financial statements of Streamex Exchange Corporation for the year ended December 31, 2024, issued going concern explanatory paragraphs in their reports, indicating that there is substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern depends on our ability to obtain additional financing, generate sufficient revenue and achieve profitability. There can be no assurance that we will satisfy the conditions required to obtain the funds under our agreements with Yorkville, or that we will be successful in securing additional financing on favorable terms, or at all, or that we will achieve positive cash flow or profitability in the future. If we are unable to address these risks, our business, financial condition, and results of operations could be materially and adversely affected.

Risks Related to our Convertible Debentures and Potential Future Indebtedness

Our level and terms of indebtedness could adversely affect our ability to raise additional capital to further execute on our gold-linked tokenization and treasury strategy, fund other operations, and take advantage of new business opportunities.

Our indebtedness, whether currently existing or incurred in the future, could have important consequences to us, including:

We may be unable to service our indebtedness, which could cause us to default on our debt obligations and could force us into bankruptcy or liquidation.

Our ability to make scheduled payments on and to refinance our indebtedness (whether currently existing or incurred in the future) depends, and will depend, on and is subject to our financial and operating performance, which is influenced, in part, by general economic, financial, competitive, legislative, regulatory, counterparty business, and other risks that are beyond our control, including the availability of financing in the U.S. banking and capital markets. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek additional capital, or restructure or refinance our indebtedness. We cannot assure you that future borrowings will be available to us in an amount sufficient to enable us to service our indebtedness, to refinance our indebtedness, or to fund our other liquidity needs. Even if refinancing indebtedness is available, any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants that could further restrict our business operations. In addition, our gold-linked tokenization and treasury strategy anticipates that we may issue additional debt in future periods to finance additional purchases of pre-buy gold delivery contracts, but if we are unable to generate sufficient cash flow to service our debt and make necessary capital expenditures, we may be required to sell gold-linked tokens or liquidate related assets. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations or our financial covenants, which could cause us to default on our debt obligations. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness.

Upon the occurrence of an event of default under our indebtedness (whether currently existing or incurred in the future), the holders of the defaulted indebtedness could elect to declare all the funds borrowed to be due and payable, together with accrued and unpaid interest. Any of these events could in turn result in cross-defaults under any other indebtedness. We may not have sufficient funds available to pay the amounts due upon any such default, particularly in the event that there has been a decrease in the market value of our gold-linked tokens or related gold assets, and we may not be able to raise additional funds to pay such amounts on a timely basis, on terms we find acceptable, or at all. Any financing that we may undertake under such circumstances could result in substantial dilution of our existing stockholders, and in the absence of being able to obtain such financing, we could be forced into bankruptcy or liquidation.

Despite our current level of indebtedness, we may incur substantially more indebtedness and enter into other transactions in the future which could further exacerbate the risks related to our indebtedness.

Our gold tokenization strategy includes financing the acquisition of pre-purchased gold delivery contracts and related gold-linked digital instruments using proceeds from equity and debt financings and, potentially, cash flows from operations. As such, despite our current level of indebtedness, we may incur substantially more indebtedness, and we may enter into other transactions in the future. Even if we were to enter into debt or other arrangements that contain restrictions on our ability to incur additional indebtedness, these restrictions may be subject to a number of qualifications and exceptions that would allow us to incur significant additional indebtedness. To the extent we incur additional indebtedness or other obligations, the risks described herein with respect to our indebtedness may increase significantly.

Future resales of our common stock as a result of registration rights granted to Yorkville in connection with the Convertible Debentures may cause the market price of our securities to drop significantly, even if our business is doing well.

In connection with our issuance of the Convertible Debentures to Yorkville, we have agreed to file and cause to be declared effective a resale registration statement (the “Resale Registration Statement”) to register for resale all of the shares of our common stock issuable upon conversion of the Convertible Debentures, including shares that may be issued pursuant to the anti-dilution provisions of the Convertible Debentures and any shares issuable as a result of stock splits, stock dividends, recapitalizations or similar events. The availability of such a large number of shares for resale under the Resale Registration Statement, particularly shortly after the registration statement becomes effective, could create significant downward pressure on the market price of our common stock.

In addition, following the effectiveness of the Resale Registration Statement, Yorkville may convert all or a portion of the Convertible Debentures and resell the Conversion Shares in the public market at its discretion, subject only to contractual and regulatory limitations. This could result in substantial dilution to our existing stockholders, especially given the conversion price formula based on market prices, and may further increase the volatility of our stock price. Sales of substantial amounts of our common stock by Yorkville or the perception that such sales could occur may also impair our ability to raise capital through the future sale of equity securities at a time and at a price that we deem appropriate or necessary.

Moreover, because the registration of the Conversion Shares is a condition to the closing of the Second Secured Convertible Debenture in the principal amount of $25 million, we are contractually obligated to complete the registration process. If we fail to do so within the required timeframe, we may be subject to penalties or be unable to access the remaining capital under the DPA, which could adversely affect our liquidity and financial condition.

Risks Related to This Offering by the Selling Shareholders

Sales of a substantial number of our securities in the public market by the Selling Shareholders and/or by our existing stockholders could cause the price of our shares of Common Stock to fall.

The sale of all or a portion of Common Stock being offered in this prospectus could result in a significant decline in the public trading price of our Common Stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Upon the expiration or waiver of the lock-ups described above, shares held by certain of our stockholders will be eligible for resale, subject to, in the case of certain stockholders, volume, manner of sale and other limitations under Rule 144. As restrictions on resale end, the market price of shares of Common Stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of Common Stock or other securities. Despite such a decline in the public trading price, some of the Selling Shareholders may still experience a positive rate of return on the securities they purchased due to the price at which such Selling Shareholders initially purchased the securities.

In addition, sales of a substantial number of our shares of Common Stock in the public market by the Selling Shareholders and/or by our other existing stockholders, or the perception that those sales might occur, could depress the market price of our shares of Common Stock and could impair our ability to raise capital through the sale of additional equity securities.

Substantial future sales of shares of Common Stock could cause the market price of our shares of Common Stock to decline.

We have agreed, at our expense, to prepare and file with the SEC certain registration statements providing for the resale of shares of Common Stock, including the registration statement of which this prospectus forms a part. The resale, or expected or potential resale, of a substantial number of our shares of Common Stock in the public market could adversely affect the market price for our shares of Common Stock and make it more difficult for you to sell your shares of Common Stock at times and prices that you feel are appropriate. Furthermore, we expect that, because there will be a large number of shares registered, the Selling Shareholders will continue to offer such covered securities for a significant period of time, the precise duration of which cannot be predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to a registration statement may continue for an extended period of time.

The issuances of additional shares of Common Stock pursuant to the conversion of the Convertible Debentures may result in dilution of holders of Common Stock and have a negative impact on the market price of the Common Stock.

Pursuant to the pursuant to the Convertible Debentures, we may initially issue up to 13,278,097 shares of Common Stock to Yorkville at a conversion price of $4.00 per share (subject to adjustments) under the First Secured Convertible Debenture and up to 13,278,097 shares of Common Stock to Yorkville at a conversion price of $4.00 per share (subject to adjustments) under the Second Secured Convertible Debenture.

Upon effectiveness of the registration statement of which this prospectus forms a part, Yorkville may resell all, some or none of their shares of Common Stock beneficially owned by it from time to time in its discretion and at different prices. The Selling Shareholders may also resell all, some, or none of their shares of Common Stock beneficially owned by them from time to time in its discretion and at different prices. As a result, investors will likely pay different prices for those shares, and so may experience different levels of dilution (and in some cases substantial dilution) and different outcomes in their investment results. Investors may experience a decline in the value of the shares they purchase as a result of future issuances by the Company, whether to the Selling Shareholders or others at prices lower than the prices such investors paid for their shares. In addition, if we issue a substantial number of shares to such parties, or if investors expect that we will do so, the actual sales of shares or the mere existence of any of the Convertible Debentures that are outstanding may adversely affect the price of our Common Stock or make it more difficult for us to sell equity or equity-related securities in the future at a desirable time and price, or at all.

The issuance, if any, of Common Stock would not affect the rights or privileges of the Company’s existing stockholders, except that the economic and voting interests of existing shareholders would be diluted. Although the number of shares of Common Stock that existing shareholders own would not decrease as a result of these additional issuances, the shares of Common Stock owned by existing shareholders would represent a smaller percentage of the total outstanding shares of Common Stock after any such issuance, potentially significantly smaller.

The Debentures are secured by the assets, present and future, of the Company and its subsidiaries, and the Company is subject to financial covenants and other restrictions on its actions in connection with the Convertible Debentures, which security and restrictions may cause significant risks to our stockholders and may impact our ability to operate our business. Any failure to meet our debt and other financial obligations or maintain compliance with related covenants could harm our business, financial condition, and results of operations.

In connection with the Convertible Debentures, we have granted a first priority security interest to Yorkville in substantially all of the existing and future assets of the Company and its subsidiaries, including Streamex, but excluding $25,100,000 of proceeds of the convertible debentures to be used to purchase Allocated Vaulted Gold Bullion for the account of Gold SPV. In connection  with the Convertible Debentures, we have also agreed to certain financial covenants, including covenants that materially limit our ability to take certain actions, including our ability to make certain payments, incur additional indebtedness, encumber and dispose of assets, and customary events of default, including failure to pay amounts due, breaches of covenants and warranties, material adverse effect events, certain cross defaults and judgements and insolvency. A failure to comply with the covenants and other provisions of the Convertible Debentures including any failure to make a payment when required, would generally result in events of default under such instruments. For a more complete description of the Convertible Debentures and the U.S. and Canadian Guaranty and Security Agreements, please see “Material Relationships with Selling Shareholders.”

Our ability to make scheduled payments on the Convertible Debentures and other financial obligations and comply with financial covenants depends on our financial and operating performance. Our financial and operating performance will continue to be subject to prevailing economic conditions and to financial, business, and other factors, some of which are beyond our control. Failure within any applicable grace or cure periods to make such payments, comply with the financial covenants, or any other non-financial or restrictive covenant, would create a default under the Initial Note (and any additional Notes we may issue). Our cash flow and existing capital resources may be insufficient to repay our debt on each payment date and at maturity, in which case we would have to extend such payment date or maturity date, as applicable, or otherwise repay, refinance, and/or restructure the obligations under the Convertible Debentures, including with proceeds from the sale of assets, and additional equity or debt capital. If we are unsuccessful in obtaining such extension, or entering into such repayment, refinance, or restructure prior to any payment date or maturity, as applicable, or any other default existed under the Convertible Debentures, the interest rate would increase during the period of such default, the note holder would have an option to convert all or any portion of the Convertible Debentures at a lower conversion price, and Yorkville would have the right to require us to redeem all or any portion of the Convertible Debentures, which may jeopardize our ability to continue our current operations and result in a material adverse effect on us.

Our failure to meet the continued listing requirements of Nasdaq could result in a delisting of our common stock, which could negatively impact the market price and liquidity of our common stock and our ability to access the capital markets.

Our common stock is listed on the Nasdaq Capital Market. If we fail to satisfy the continued listing requirements of Nasdaq, such as the minimum bid price, shareholders’ equity, public float and other requirements, Nasdaq may take steps to delist our common stock. Such a delisting would have a negative effect on the price of our common stock, impair the ability to sell or purchase our common stock when persons wish to do so, and any delisting materially adversely affect our ability to raise capital or pursue strategic restructuring, refinancing or other transactions on acceptable terms, or at all. Delisting from the Nasdaq Capital Market could also have other negative results, including the potential loss of institutional investor interest and fewer business development opportunities. In the event of a delisting, we would attempt to take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements.

SELLING SHAREHOLDERS

This prospectus relates to the offer and sale, from time to time, of up to 27,885,987 shares of our Common Stock by the stockholder identified in the table below, who we refer to in this prospectus as the “Selling Shareholders” and its respective transferees, pledgees, donees, assignees or other successors (each also a Selling Shareholder for purposes of this prospectus). The Selling Shareholders identified below may currently hold or acquire at any time shares of our Common Stock in addition to those registered hereby.

We are registering these 26,556,194 shares of our Common Stock for sale by the Selling Shareholders named below pursuant to the DPA, the Convertible Debentures, and the Share Purchase Agreement, as described below.

The percent of beneficial ownership for the Selling Shareholders is based on 148,610,687 shares of Common Stock outstanding as of November 17, 2025. Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to such securities. Except as otherwise indicated, the Selling Shareholders listed below have sole voting and investment power with respect to the shares of our Common Stock beneficially owned by it.

Information concerning the Selling Shareholders may change from time to time and any changed information will be set forth in supplements to this prospectus, if and when necessary. No offer or sale under this prospectus may be made by a stockholder unless that holder is listed in the table below, in any supplement to this prospectus or in an amendment to the related registration statement that has become effective. We will supplement or amend this prospectus if applicable to include additional Selling Shareholders upon provision of all required information to us and subject to the terms of any relevant agreement between us and the Selling Shareholders.

The Selling Shareholders are not obligated to sell any of the shares of our securities offered by this prospectus. Because the Selling Shareholders identified in the table below may sell some or all of the shares of our securities owned by them that are included in this prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of such securities, no estimate can be given as to the number of securities covered by this prospectus that will be held by the Selling Shareholders.

In addition, subject to applicable law, the Selling Shareholders may sell, transfer or otherwise dispose of, at any time and from time to time, shares of our securities they hold in transactions exempt from the registration requirements of the Securities Act after the date on which the Selling Shareholders provided the information set forth on the table below. Therefore, for purposes of the following table we have assumed that the Selling Shareholders will sell all of the shares of our Common Stock beneficially owned by it that are covered by this prospectus but will not sell any other shares of our Common Stock that it may currently own.

Material Relationships with Selling Shareholders

Share Purchase Agreement

On May 23, 2025, we entered into the Share Purchase Agreement with Streamex, ExchangeCo, CallCo, each shareholder of Streamex and the Trustee. Pursuant to the Share Purchase Agreement, the Company, through ExchangeCo, agreed to acquire all of the issued and outstanding shares of Streamex (the “Purchased Shares”) from the Shareholders. In exchange for the Purchased Shares, upon the closing of the transaction (the “Closing”), ExchangeCo issued an aggregate of 109,070,056.6977 exchangeable shares in its capital stock (the “Exchangeable Shares”), at a ratio of 2.046862 Exchangeable Shares for each Purchased Share. The Exchangeable Shares are exchangeable on a one-for-one basis (the “Exchange Ratio”), subject to certain adjustments, for shares of the Company’s common stock and will carry rights substantially equivalent to the Company’s common stock, as set forth in the Exchange Rights Agreement. The Company was required to file a registration statement with the SEC to register the resale of the shares of common stock issuable upon exchange of the Exchangeable Shares.

Initially, upon the Closing and in accordance with Nasdaq listing rules, the Exchangeable Shares were not exchangeable into more than 19.9% of the Company’s outstanding common stock on a pre-transaction basis. Following the Closing, the Company was required to seek stockholder approval for exceeding such cap and of certain other matters set out in the Share Purchase Agreement. As a result of obtaining such approval November 4, 2025, the holders of Exchangeable Shares are now entitled to receive, together with the initial issuance, an aggregate total number of shares equal to 75% of the fully diluted shares of the Company’s common stock outstanding as of the date of the Share Purchase Agreement. As a result of Nasdaq’s change of control rules, the Company filed a new initial listing application for its common stock, which was approved on October 30, 2025.

First Amendment to Share Purchase Agreement

On May 27, 2025, we entered into the Amendment to the Share Purchase Agreement with the other parties. The Amendment to the Share Purchase Agreement revised the Share Purchase Agreement to clarify that ExchangeCo will issue 2.046862 of its exchangeable shares (the “Exchangeable Shares”) to the shareholders of Streamex for each share of Streamex previously held, rather than 2.05 as originally set forth in the Share Purchase Agreement, for an aggregate issuance of 109,070,056.6977 Exchangeable Shares.

The transactions under the Share Purchase Agreement as amended closed on May 28, 2025.

Pursuant to the requirements of the DPA, certain of the Exchangeable Shareholders holding an aggregate of 98,034,766 Exchangeable Shares waived their registration rights for and during the terms of the Convertible Debentures.

For additional information regarding the Share Purchase Agreement, please see our Current Reports on Form 8-K filed with the SEC on July 9, 2025, August 13, 2025, October 29, 2025, and November 6, 2025, and the documents filed therewith or incorporated therein by reference.

Debenture Purchase Agreement

On July 7, 2025, the Company entered into the DPA with Yorkville, pursuant to which Yorkville may purchase senior secured convertible debentures in the aggregate principal amount of up to $50,000,000, with an additional option to purchase $50,000,000 in aggregate principal amount upon mutual agreement of the parties, (the “Convertible Debentures”), which will be convertible into shares of the Company’s Common Stock.

Amendment No. 1 to the DPA

On August 13, 2025, the Company entered into Amendment No. 1 to the DPA (the “First Amendment”) with Yorkville to, among other things, revise the structure of the transaction to provide for a first secured convertible debenture in the principal amount of $25,000,000, a second secured convertible debenture in the principal amount of $25,000,000, and additional secured convertible debentures in an aggregate principal amount of up to $50,000,000 to be issued upon mutual agreement of the parties, which agreement may be withheld in either parties sole discretion; modify certain purchase, closing and stockholder approval provisions; and update related terms, including setting the conversion floor price for conversions at 20% of the Nasdaq Official Closing Price immediately prior to the date of entry into the DPA.

Amendment No. 2 to the DPA

On October 28, 2025, the Company entered into Amendment No. 2 to the DPA (the “Second Amendment”) with Yorkville to, among other things: (i) mandate that at least $25.1- million in aggregate proceeds — $12.6 million at the First Closing (as defined by the DPA) and $12.5 million at the Second Closing (as defined by the SPA) — be deposited directly to a certain securities account for the sole purpose of purchasing Allocated Vaulted Gold Bullion (as defined in the U.S. and Canadian Guaranty and Security Agreements, dated November 4, 2025 (the “GSAs”), entered into by, and made by, the Company and its affiliates party thereto, in favor of Yorkville, as collateral agent for itself and the other secured parties. Additionally, pursuant to the Second Amendment, the conversion floor price under the Convertible Debentures was revised from the previously disclosed conversion floor price to $4.00.

Amendment No. 3 to the DPA

On November 4, 2025, the Company entered into a certain Amendment No. 3 to the DPA (the “Third Amendment”) with Yorkville. The Third Amendment further amended the DPA, adding additional closing conditions with no material terms amended.

Debentures

On November 4, 2025, the Company consummated the sale of the First Secured Convertible Debenture in the principal amount of $25,000,000 to Yorkville. The purchase price for the First Secured Convertible Debenture was 96.0% of its principal amount, or $24,000,000 (before payment of placement agent fees, legal fees and other expenses). The First Secured Convertible Debenture was issued in a private placement in reliance upon an exemption from registration provided by Section 4(a)(2) of the Securities Act. Under the DPA, Yorkville may purchase, and the Company may issue, a second Convertible Debenture, the Second Secured Convertible Debenture in the principal amount of $25,000,000 to Yorkville, following the satisfaction of the conditions set forth in the DPA, and certain additional Secured Convertible Debentures in an aggregate principal amount of up to $50,000,000, upon mutual agreement of the parties, which agreement may be withheld in either party’s sole discretion. The purchase price for the Second Secured Convertible Debenture is slated to be 96.0% of its principal amount. The sale and purchase of the Second Secured Convertible Debenture is conditioned upon this registration statement having been declared effective by the SEC, as elaborated and stated under the Registration Rights Agreement (as defined below).

Each Debenture will mature 24 months after its issuance, and will accrue interest at the rate of 4.00% per annum, which will increase to 18.00% per annum upon the occurrence of an event of default, until such event of default is cured. The principal must be paid in cash on the maturity date or earlier upon acceleration or conversion. Interest shall be provided in cash or, at the election of the Company, in kind through the issuance of shares of Common Stock underlying the Convertible Debentures (collectively, the “Debenture Shares”) upon conversion of the Debenture in accordance with the terms thereof. Each debenture provides that Yorkville may convert all or any portion of the principal amount of the applicable debenture, together with any accrued and unpaid interest thereon, at a conversion price equal to the lower of: (i) a fixed price per share that will be equal to 125% of the volume-weighted average price (“VWAP”) of the Common Stock on the day prior to the initial closing, subject to a one-time, downward only reset equal to 125% of the average of the daily VWAP for the Common Stock during the five consecutive trading days ending on and including the 30th trading day following the effectiveness of the registration statement registering the resale of the Debenture Shares, as described below (the “Resale Registration Statement”), and (ii) 97.0% of the lowest daily VWAP for the Common Stock during the three trading days immediately preceding the applicable conversion date or other date of determination, subject to a Floor Price of $4.00 per share, in each case subject to adjustment as provided in the Convertible Debentures, including adjustments for stock splits, dividends, and other customary anti-dilution provisions. Yorkville would not be permitted to issue or convert the Convertible Debentures to the extent that the Debenture Shares deliverable upon such conversion would exceed 19.99% of the Company’s outstanding Common Stock as of the date of the DPA, including the shares issued in the previously announced acquisition of Streamex (the “Exchange Cap”), subject to certain aggregation adjustments under applicable rules of the Nasdaq Stock Market LLC (“Nasdaq”), unless and until approval of the Company’s stockholders has been obtained to permit issuances in excess of the Exchange Cap or the Company obtains a legal opinion satisfactory to the Investor that such approval is not required under applicable Nasdaq rules.

The Company has the option to prepay, in part or in whole, the outstanding principal and interest under either of the Convertible Debentures prior to the maturity date, plus a prepayment premium of 10% of the principal amount of the applicable debenture; provided that the Company delivers at least ten trading days’ prior written notice of such prepayment, during which period the holder retains the right to convert all or any portion of either the First Secured Convertible Debenture or the Second Secured Convertible Debenture. The Debentures also provide for certain rights of the holder in the event the Company issues additional securities or incurs additional indebtedness, subject to the covenants set forth in the transaction documents. Standard events of default are included in the Convertible Debentures, pursuant to which the holder may declare the Convertible Debentures immediately due and payable and exercise other remedies, including the right to foreclose on the collateral securing the obligations. The DPA also contains customary representation and warranties of the Company and Yorkville, indemnification obligations of the Company, termination provisions, and other obligations and rights of the parties. The Investor shall not have the right to convert any portion of the Convertible Debentures if, after giving effect to such conversion, the Investor, together with its affiliates, would beneficially own more than 4.99% of the outstanding Common Stock immediately following such conversion, as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder.

U.S. and Canadian Guaranty and Security Agreements

The obligation of the Company under the DPA, as amended, the Convertible Debentures and related agreements are secured by a first priority security interest in substantially all of the existing and future assets of the Company and its subsidiaries, including Streamex, but excluding $25,100,000 of proceeds of the convertible debentures to be used purchase Allocated Vaulted Gold Bullion for the account of Gold SPV,  pursuant to (i) the U.S. and Canadian GSAs, under which the Company and its subsidiaries granted a security interest in favor of Yorkville in their respective assets, including accounts, inventory, equipment, intellectual property (other than Excluded Property), investment property, deposit accounts, and other collateral as defined therein, and (ii) related control agreements and collateral documents delivered in connection therewith. Pursuant to the GSAs, Streamex and other subsidiaries unconditionally guaranteed the prompt and complete payment and performance of all obligations of the Company under the Convertible Debentures and related transaction documents.

Registration Rights Agreement

In connection with the DPA, the Company also entered into a Registration Rights Agreement with Yorkville, pursuant to which the Company agreed to file the current resale registration statement, and any additional registration statement as needed, with the SEC to register for resale the following shares: (i) the Common Shares issuable upon conversion of the convertible debentures of up to $100,000,000  in aggregate under the DPA, (ii) any additional shares issuable in connection with any anti-dilution provisions of the Convertible Debentures (without giving effect to any limitations on conversion set forth in the Convertible Debentures), and (iii) any Common Stock issued or issuable with respect to any shares described in (i) and (ii) above by way of any stock split, stock dividend or other distribution, recapitalization or similar event or otherwise, in each case subject to any cutback as set forth in the Registration Rights Agreement. The Company agreed to register at least such number of Common Stock as shall equal the maximum number of Common Stock issuable upon conversion of all debentures then outstanding (assuming for purposes hereof that any such conversion shall not take into account any limitations on the conversion of the Convertible Debentures set forth therein), subject to any limitations set forth in the Registration Rights Agreement.

Lock-Up Agreement

Prior to the closing of the First Secured Convertible Debenture, each of the directors, officers, and certain stockholders of the Company entered into Lock-Up Agreements (collectively, the “Lock-Up Agreements”) with the placement agents. Pursuant to the Lock-Up Agreements, each such party agreed that the shares of Common Stock (including securities convertible into or exercisable or exchangeable for the Company; Common Stock) held by them will be subject to transfer restrictions for a period of 180 days following the issuance of the First Secured Convertible Debenture, subject to certain exceptions.

For more information regarding the DPA, the Debentures and the related agreements, please see our Current Reports on Form 8-K filed with the SEC on July 9, 2025, August 13, 2025, October 29, 2025, November 6, 2025, and the documents filed therewith or incorporated therein by reference.

SEPA

Simultaneously with the DPA executed on July 7, 2025, the Company had also entered into a Standby Equity Purchase Agreement (the “SEPA”) with Yorkville, pursuant to which the Company has the right, but not the obligation, to issue and sell to the Investor up to $1,000,000,000 of its Common Stock, from time to time during the 36-month commitment period under the SEPA, subject to certain terms, limitations and conditions. The Company will control the timing and amount of any sales of Common Stock to Yorkville under the SEPA at its discretion, and as further provided under the SEPA.

Pursuant to the SEPA, the Company may from time to time deliver an advance notice (an “Advance Notice”) to Yorkville specifying the number of Common Stock it elects to sell, but shall not deliver an Advance Notice until any issued debenture(s) has been repaid and/or converted in full, except for the prior written consent of Yorkville permitting such Advance Notice. Each Advance Notice will be priced at 97% of the lowest VWAP of the Common Stock during the three consecutive trading days commencing on the date the Advance Notice is received by the Investor, subject to certain adjustments if the daily VWAP is below a minimum acceptable price that may be specified by the Company in the Advance Notice. No Advance Notice may cause the Investor’s beneficial ownership to exceed 4.99% of the Company’s outstanding Common Stock.

The Company may, in the future, file a registration statement with the SEC to register for resale the Common Stock issuable under the SEPA. The Investor’s obligation to purchase Common Stock under the SEPA is subject to customary closing conditions, including the effectiveness of the registration statement to be filed pursuant to it.

As consideration for Yorkville’s commitments under the SEPA, the Company agrees to pay to Yorkville a commitment fee equal to 1.0% of the commitment amount, with the initial payment due concurrently with the first closing of a sale under the SEPA, and the balance payable in equal quarterly installments within fifteen days after the end of the applicable calendar quarter, in either (i) cash, or (ii) shares of Common Stock, at the Investor’s discretion (with the number of shares issuable to the Investor determined by dividing the dollar amount of the commitment fee then due by the closing price of the Common Stock of the last day of the applicable calendar quarter.

The SEPA contains customary representations, warranties, covenants, conditions and indemnification obligations of the parties. The SEPA will terminate automatically on the earliest of (i) 36 months after the date of execution, or (ii) the date Yorkville has purchased the full commitment amount of Common Stock. The Company may also terminate the SEPA at any time without fee or penalty upon five business days’ written notice to Yorkville, provided there are no pending Advance Notices.

For more information regarding the SEPA, please see our Current Report on Form 8-K filed with the SEC on July 9, 2025, and the documents filed therewith or incorporated therein by reference.

Shareholder Approvals

On September 5, 2025, and November 4, 2025, a majority of our shareholders approved the issuance of the shares of Common Stock pursuant to the terms of the Share Purchase Agreement, the DPA, the Convertible Debentures, and the SEPA, among other things. We are thus permitted to convert the Convertible Debentures into shares of Common Stock in excess of the Exchange Cap (as defined in the DPA) and are able to issue to Yorkville Common Stock under the SEPA in excess of the Exchange Cap (as defined in the SEPA), as applicable. We are also permitted to issue all of the shares of Common Stock pursuant to the Share Purchase Agreement, pursuant to such shareholder approval received on November 4, 2025.

USE OF PROCEEDS

All of the securities offered by the Selling Shareholders pursuant to this prospectus will be sold by the Selling Shareholders for their own account. We will not receive any of the proceeds from these sales.

The Selling Shareholders will pay any underwriting discounts and selling commissions and pay any brokerage fees or commissions and expenses incurred by them for brokerage, accounting, tax or legal services or any other expenses incurred in selling the securities. We will bear the costs, fees and expenses incurred in effecting the registration of the securities covered by this prospectus, including all registration and filing fees, Nasdaq listing fees and fees and expenses of our counsel and our independent registered public accounting firm.

DESCRIPTION OF CAPITAL STOCK

The following description of capital stock summarizes the material terms and provisions of the Common Stock which may be resold under this prospectus, but is not complete. For the complete terms of our Common Stock and preferred stock, please refer to our amended and restated certificate of incorporation, as amended, any certificates of designation for our preferred stock, and our amended and restated bylaws, as amended. While the terms we have summarized below will apply generally to any future Common Stock or preferred stock that we may offer, we will describe the specific terms of any series of preferred stock in more detail in the applicable prospectus supplement. If we so indicate in a prospectus supplement, the terms of any preferred stock we offer under that prospectus supplement may differ from the terms we describe below.

We have authorized 501,000,000 shares of capital stock, par value $0.001 per share, of which 500,000,000 are shares of Common Stock and 1,000,000 are shares of “blank check” preferred stock, of which one (1) is authorized as Special Voting Preferred Stock, 200 are authorized as Series A Preferred Stock, 600 are authorized as Series B Preferred Stock, 4,200 are authorized as Series C Preferred Stock, 1,400 are authorized as Series D Preferred Stock, 1,000 are authorized as Series E Preferred Stock and 200,000 are authorized as Series F Junior Participating Preferred Stock. As of November 17, 2025, there were 39,540,603 shares of Common Stock issued and outstanding, 1 share of Special Voting Preferred Stock issued and outstanding, 105 shares of Series C Preferred Stock issued and outstanding, no shares of our Series A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series D Convertible Preferred Stock, Series E Convertible Preferred Stock or Series F Junior Participating Preferred Stock issued and outstanding. The authorized and unissued shares of Common Stock and the authorized and undesignated shares of preferred stock are available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange on which our securities may be listed. Unless approval of our stockholders is required, our board of directors does not intend to seek stockholder approval for the issuance and sale of our common stock or preferred stock.

Common Stock

The holders of Common Stock are entitled to one vote per share on all matters to be voted upon by stockholders. Holders of our Common Stock are entitled to receive ratably dividends as may be declared by the board of directors out of funds legally available for that purpose. We have never paid cash dividends on our common stock and do not anticipate paying any cash dividends in the foreseeable future but intend to retain our capital resources for reinvestment in our business. Any future disposition of dividends will be at the discretion of our board of directors and will depend upon, among other things, our future earnings, operating and financial condition, capital requirements, and other factors.

Each share of Common Stock entitles the holder to one vote, either in person or by proxy, at meetings of stockholders. The holders are not permitted to vote their shares cumulatively. Accordingly, the stockholders of our common stock who hold, in the aggregate, more than fifty percent of the total voting rights can elect all of our directors and, in such event, the holders of the remaining minority shares will not be able to elect any of such directors. The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on any matter other than the election of directors that is presented to stockholders at a duly called or convened meeting at which a quorum is present is sufficient to authorize, affirm, ratify or consent to such act or action, except as otherwise provided by our certificate of incorporation, our bylaws, the rules or regulations of any stock exchange applicable to us, or applicable law or pursuant to any regulation applicable to us or our securities.

Holders of our Common Stock have no preemptive rights or other subscription rights, conversion rights, redemption or sinking fund provisions. Subject to the rights of the holders of our preferred stock, upon our liquidation, dissolution or winding up, the holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities.

The transfer agent and registrar for our common stock is Securities Transfer Corporation. The transfer agent’s address is 2901 N. Dallas Parkway, Suite 380, Plano, TX 75093. Our Common Stock is listed on The Nasdaq Capital Market under the symbol “STEX.”

Preferred Stock

The board of directors is authorized, subject to any limitations prescribed by law, without further vote or action by the stockholders, to issue from time to time shares of preferred stock in one or more series. Each such series of preferred stock shall have such number of shares, designations, preferences, voting powers, qualifications, and special or relative rights or privileges as shall be determined by the board of directors, which may include, among others, dividend rights, voting rights, liquidation preferences, conversion rights and preemptive rights. Issuance of preferred stock by our board of directors may result in such shares having dividend and/or liquidation preferences senior to the rights of the holders of our common stock and could dilute the voting rights of the holders of our common stock.

Prior to the issuance of shares of each series of preferred stock, the board of directors is required by the Delaware General Corporation Law (the “DGCL”) and our certificate of incorporation to adopt resolutions and file a certificate of designation with the Secretary of State of the State of Delaware. The certificate of designation fixes for each class or series the designations, powers, preferences, rights, qualifications, limitations and restrictions, including, but not limited to, some or all of the following:

Once designated by our board of directors, each series of preferred stock may have specific financial and other terms that will be described in a prospectus supplement. The description of the preferred stock that is set forth in any prospectus supplement is not complete without reference to the documents that govern the preferred stock. These include our certificate of incorporation and any certificates of designation that our board of directors may adopt.

All shares of preferred stock offered hereby will, when issued, be fully paid and nonassessable, including shares of preferred stock issued upon the exercise of preferred stock warrants or subscription rights, if any.

Although our board of directors has no intention at the present time of doing so, it could authorize the issuance of a series of preferred stock that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt.

Anti-Takeover Effects of Certain Provisions of Delaware Law, our Certificate of Incorporation and Bylaws

Delaware Law

We are subject to Section 203 of the DGCL. Section 203 generally prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

Section 203 defines a business combination to include:

In general, Section 203 defines an “interested stockholder” as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with, or controlling, or controlled by, the entity or person. The term “owner” is broadly defined to include any person that, individually, with or through that person’s affiliates or associates, among other things, beneficially owns the stock, or has the right to acquire the stock, whether or not the right is immediately exercisable, under any agreement or understanding or upon the exercise of warrants or options or otherwise or has the right to vote the stock under any agreement or understanding, or has an agreement or understanding with the beneficial owner of the stock for the purpose of acquiring, holding, voting or disposing of the stock.

The restrictions in Section 203 do not apply to corporations that have elected, in the manner provided in Section 203, not to be subject to Section 203 of the DGCL or, with certain exceptions, which do not have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders. Our certificate of incorporation and bylaws do not opt out of Section 203.

Section 203 could delay or prohibit mergers or other takeover or change in control attempts with respect to us and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

Certificate of Incorporation and Bylaws

Provisions of our certificate of incorporation and bylaws may delay or discourage transactions involving an actual or potential change in our control or change in our management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our certificate of incorporation and bylaws:

PLAN OF DISTRIBUTION

We are registering the offer and sale from time to time by the Selling Shareholders, or their permitted transferees, of up to 27,885,987 shares of our Common Stock.

The shares of Common Stock offered by this prospectus are being offered by the Selling Shareholders. The shares of Common Stock may be sold or distributed from time to time by the Selling Shareholders directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the shares of Common Stock offered by this prospectus could be effected in one or more of the following methods:

In order to comply with the securities laws of certain states, if applicable, the shares of Common Stock may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the shares of Common Stock may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.

The Selling Shareholders may be deemed as “underwriters” within the meaning of Section 2(a)(11) of the Securities Act.

The Selling Shareholders have informed us that they intend to use one or more registered broker-dealers to effectuate all sales, if any, of our Common Stock that it has acquired and may in the future acquire from us pursuant to the DPA, the Convertible Debentures, or otherwise. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such registered broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. The Selling Shareholders have informed us that each such broker-dealer will receive commissions from the Selling Shareholders that will not exceed customary brokerage commissions.

Brokers, dealers, underwriters or agents participating in the distribution of the shares of our Common Stock offered by this prospectus may receive compensation in the form of commissions, discounts, or concessions from the purchasers, for whom the broker-dealers may act as agent, of the shares of Common Stock sold by the Selling Shareholders through this prospectus. The compensation paid to any such particular broker-dealer by any such purchasers of shares of our Common Stock sold by the Selling Shareholders may be less than or in excess of customary commissions. Neither we nor the Selling Shareholders can presently estimate the amount of compensation that any agent will receive from any purchasers of shares of our Common Stock sold by the Selling Shareholders.

We know of no existing arrangements between the Selling Shareholders or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the shares of our Common Stock offered by this prospectus.

We may from time to time file with the SEC one or more supplements to this prospectus or amendments to the registration statement of which this prospectus forms a part to amend, supplement or update information contained in this prospectus, including, if and when required under the Securities Act, to disclose certain information relating to a particular sale of shares of Common Stock offered by this prospectus by the Selling Shareholders including the names of any brokers, dealers, underwriters or agents participating in the distribution of such shares of Common Stock by the Selling Shareholders any compensation paid by the Selling Shareholders to any such brokers, dealers, underwriters or agents, and any other required information.

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the shares of our Common Stock covered by this prospectus by the Selling Shareholders. We have reserved up to 26,556,193 shares of our Common Stock that we may issue to Yorkville as shares issuable pursuant to the conversion of the Convertible Debentures.

We also have agreed to indemnify the Selling Shareholders and certain other persons against certain liabilities in connection with the offering of shares of our Common Stock offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. The Selling Shareholders have agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by the Selling Shareholders specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.

The Selling Shareholders have represented to us that at no time prior to the date of the DPA has the Selling Shareholders or their agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of our Common Stock or any hedging transaction, which establishes a net short position with respect to our Common Stock. Yorkville has agreed that during the term of the DPA, Debentures, neither Yorkville nor any of its agents, representatives or affiliates will enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised the Selling Shareholders that they are required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the Selling Shareholders, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security that is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering will terminate on the date that all shares of our Common Stock offered by this prospectus have been sold by the Selling Shareholders.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol “STEX.” On November 17, 2025, the closing price of our Common Stock was $3.73.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth the estimated costs and expenses payable by the registrant expected to be incurred in connection with the issuance and distribution of the common stock being registered hereby (other than underwriting discounts and commissions). All of such expenses are estimates, except for the SEC registration fee and FINRA fee.

Each of the amounts set forth above, other than the registration fee and FINRA fee, is an estimate.

Item 15. Indemnification of Directors and Officers.

Set forth below is a description of certain provisions of the Company’s Amended and Restated Certificate of Incorporation, as amended to date (the “Certificate of Incorporation”) and Amended and Restated Bylaws, as amended to date (the “Bylaws”), and the Delaware General Corporation Law (the “DGCL”). This description is intended as a summary only and is qualified in its entirety by reference to the Certificate of Incorporation, the Bylaws and the DGCL.

Limitation on Liability of Directors

Article IX of the Certificate of Incorporation limits the personal liability of directors to the Company or the Company’s stockholders for monetary damages for acts or omissions occurring in their capacity as directors, to the fully extent permitted by the laws of the State of Delaware and any other applicable law, as such laws currently exist and to such greater extent as they may provide in the future.

Indemnification and Insurance

Section 145 of the DGCL provides, in general, that a corporation incorporated under the laws of the State of Delaware, as we are, may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than a derivative action by or in the right of the corporation) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if 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 action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. In the case of a derivative action, a Delaware corporation may indemnify any such person against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if 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, except that no indemnification will be made in respect of any claim, issue or matter as to which such person will have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery of the State of Delaware or any other court in which such action was brought determines such person is fairly and reasonably entitled to indemnity for such expenses.

The Certificate of Incorporation and Bylaws provide that we will indemnify our directors, officers, employees and agents to the extent and in the manner permitted by the provisions of the DGCL, as amended from time to time, subject to any permissible expansion or limitation of such indemnification, as may be set forth in any stockholders’ or directors’ resolution or by contract. Any repeal or modification of these provisions approved by our stockholders will be prospective only and will not adversely affect any limitation on the liability of any of our directors or officers existing as of the time of such repeal or modification.

We are also permitted to apply for insurance on behalf of any director, officer, employee or other agent for liability arising out of his actions, whether or not the DGCL would permit indemnification.

Item 16. Exhibits.

* Filed herewith

** To be filed vide amendment

Item 17. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (“Securities Act”);

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” or “Calculation of Registration Fee” table, as applicable, in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (“Exchange Act”) that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) If the registrant is relying on Rule 430B (§230.430B of this chapter):

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(ii) If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes that:
