PROXY STATEMENT FOR
2024 SPECIAL MEETING OF SHAREHOLDERS

TO BE HELD ON

FRIDAY, SEPTEMBER 20, 2024 AT 10:00 A.M. MDT

This management information circular and proxy statement (the “Proxy Statement”), dated , 2024, is provided in connection with the solicitation of proxies by or on behalf of the Board of Directors (the “Board”) of DIRTT Environmental Solutions Ltd. for use at the special meeting of shareholders (the “Meeting”). In this Proxy Statement, “DIRTT,” the “Company,” “we,” “us” or “our” refer to DIRTT Environmental Solutions Ltd., and “you,” “your” and “shareholder” refer to the holders of common shares of the Company (“Common Shares”). The Meeting will be held on Friday, September 20, 2024 at 10:00 a.m. MDT for the purposes set forth in the Notice of Special Meeting.

The Meeting will be held virtually, to be conducted via live audio webcast online at meetnow.global/MCX7XXF.

Registered shareholders and duly appointed and registered proxyholders may participate in the Meeting, submit questions and vote. Non-registered (beneficial) shareholders who have not duly appointed and registered themselves as proxyholders may still attend the Meeting and ask questions but will not be able to vote at the Meeting. See also “How to Vote” below.

This Proxy Statement includes information that we are required to provide to you under the rules of the applicable corporate and securities laws in Canada and the U.S. Securities and Exchange Commission (the “SEC”), and that is designed to assist you in voting your Common Shares.

This Proxy Statement contains detailed information on the matters to be considered at the Meeting, or any adjournment or postponement thereof. Please read this Proxy Statement carefully and remember to vote your Common Shares, either by proxy or online at the Meeting, or any adjournment or postponement thereof. Your vote is important.

On or about , 2024, we will begin mailing this Proxy Statement, Notice of Special Meeting and the related proxy card (collectively, the “Proxy Materials”) to shareholders entitled to vote at the Meeting containing instructions on how to vote.

We are permitted under applicable securities laws to deliver a single set of Proxy Materials to one address shared by two or more shareholders. This delivery method is referred to as “householding” and helps reduce our printing costs and postage fees. See “Other Matters – Householding” on page 23 of this Proxy Statement.

Unless otherwise indicated, references herein to “$” or “dollars” are expressed in U.S. dollars (US$), and references to Canadian dollars are noted as “C$.”

References in the Proxy Materials to the “Meeting” also refer to any adjournments, postponements or changes in location or format of the Meeting, to the extent applicable.

Shareholders of record at the close of business on August 1, 2024 (the “Record Date”) are entitled to vote at the Meeting or at any adjournment or postponement thereof, on the basis of one vote per Common Share held, unless (i) a registered shareholder has transferred the ownership of any Common Shares subsequent to the Record Date, and

(ii) the transferee shareholder produces properly endorsed share certificates, or otherwise establishes that he or she owns the Common Shares and demands, no later than 10 days before the Meeting, that his or her name be included on the shareholders list before the Meeting, in which case, the transferee shareholder shall be entitled to vote such Common Shares at the Meeting or any adjournment or postponement thereof. The transfer books will not be closed. As of the close of business on the Record Date, the Company had 192,967,643 Common Shares issued and outstanding.

A list of our shareholders of record will be available and may be inspected prior to the Meeting by contacting Investor Relations at ir@dirtt.com.

The presence, in person or by proxy, of two or more shareholders representing at least 33-1/3% of the voting power of outstanding Common Shares on the Record Date (constituting 64,322,548 votes) will constitute a quorum for the transaction of business at the Meeting and any postponement or adjournment thereof, though the Board may fix a new record date for purposes of a postponed or adjourned meeting. Shareholders will be considered present at the Meeting if they or their proxyholder are logged into the Meeting using their unique control number or username.

Abstentions and broker non-votes, to the extent we receive any, will be counted for the purpose of determining the presence or absence of a quorum.

How you vote depends on whether you are a registered or non-registered shareholder. You are a registered shareholder if the Common Shares you own are registered in your name. You are a non-registered shareholder if your Common Shares are registered in the name of an intermediary, such as a trustee, financial institution or securities broker. This is often called ownership in “street name” because your name does not appear in the records of the Company’s transfer agent, Computershare Trust Company of Canada (“Computershare”). If you are a registered shareholder, you can vote during the meeting, via the Internet, by telephone or facsimile, or by proxy, as explained below. If you hold any Common Shares in street name, you should receive a voting instruction form from the intermediary in respect of such Common Shares with further voting instructions.

If you receive more than one proxy card or voting instruction form, then you may have more than one account at Computershare, with an intermediary, or both. Please vote all proxy cards and voting instruction forms using the respective control numbers that you receive so that all of the Common Shares that you own will be represented at the Meeting.

If you are a registered shareholder (i.e., shareholder of record), there are four ways to vote:

Your completed proxy card must be received by Computershare, or you must have voted by Internet or telephone, no later than September 18, 2024 at 10:00 a.m. MDT, or in the case of adjournment or postponement, not less than 48 hours (excluding Saturdays, Sundays or holidays in Alberta) prior to the time of the adjourned or postponed Meeting or any subsequent adjournment(s) or postponement(s) thereof. The proxy card or any other instrument of proxy will not be valid for the Meeting, or any adjournment or postponement thereof, unless it is signed by you or your attorney (duly authorized in writing). The time limit for deposit of proxies may be waived or extended by the Chair of the Meeting at his or her discretion, without notice.

If you are a non-registered shareholder (i.e., beneficial owner), there are four ways to vote:

Your completed voting instruction form must be returned on or before the deadline specified on the voting instruction form. The time limit for deposit of proxies may be waived or extended by the Chair of the Meeting at his or her discretion, without notice.

The persons named in the enclosed proxy card (the “management proxyholders”) are directors or executive officers of the Company. You have the right to appoint another person (who need not be a shareholder) to represent you at the Meeting, or any adjournment or postponement thereof. To do so, insert the name of that person in the space provided in the proxy card and strike out the other names. Your Common Shares will be voted in accordance with your instructions indicated on the proxy card.

In the absence of such instructions, your Common Shares will be voted by the persons named in the enclosed proxy card as follows:

We know of no other matters to be submitted to a vote of shareholders at the Meeting. If any other matter is properly brought before the Meeting or any postponement or adjournment thereof, it is the intention of the persons named in the enclosed proxy to vote the Common Shares they represent in accordance with their best judgment on such matter.

Shareholders have the right to appoint someone other than the management proxyholders as their proxyholder. Shareholders who wish to appoint someone other than the management proxyholders as their proxyholder (including non-registered shareholders who wish to appoint themselves as proxyholder) to attend and participate at the Meeting as their proxy and vote their Common Shares must submit their proxy card or voting instruction form, as applicable, appointing that person as proxyholder AND register that proxyholder online. Registering your proxyholder is an additional step to be completed AFTER you have submitted your form of proxy or voting instruction form.

Submit your proxy card or voting instruction form. To appoint someone other than the management proxyholders as proxyholder, insert that person’s name in the blank space provided in the proxy card or voting instruction form (if permitted) and follow the instructions for submitting such proxy card or voting instruction form. This must be completed before registering such proxyholder, which is an additional step to be completed once you have submitted your proxy card or voting instruction form.

If you are a non-registered shareholder and wish to vote at the Meeting, you must insert your own name in the space provided on the voting instruction form sent to you by your intermediary, follow all of the applicable instructions provided by your intermediary AND register yourself as your proxyholder, as described below under “Registering your proxyholder.” By doing so, you are instructing your intermediary to appoint you as proxyholder. It is important that you comply with the signature and return instructions provided by your intermediary.

Additionally, if you are a non-registered shareholder located in the United States and wish to vote at the Meeting or, if permitted, appoint a third party as your proxyholder, in addition to the steps outlined above, you must also obtain a valid legal proxy from your intermediary. Follow the instructions from your intermediary included with the legal proxy form and the voting information form sent to you, or contact your intermediary to request a legal proxy form or a legal proxy if you have not received one. After obtaining a valid legal proxy from your intermediary, you must then submit such legal proxy to Computershare. Requests for registration from non-registered shareholders located in the United States that wish to vote at the Meeting or, if permitted, appoint a third party as their proxyholder must be sent by e-mail or by courier to: uslegalproxy@computershare.com (if by email), or to Computershare: 8th Floor, 100 University Avenue, Toronto, Ontario, Canada M5J 2Y1 (if by courier), and in both cases, must be labeled “Legal Proxy” and received no later than the voting deadline of September 18, 2024 at 10:00 a.m. MDT, or in the case of adjournment or postponement, not less than 48 hours (excluding Saturdays, Sundays or holidays in Alberta) prior to the time of the adjourned or postponed Meeting or any subsequent adjournment(s) or postponement(s) thereof.

Registering your proxyholder. To register a proxyholder other than the management proxyholders, shareholders must visit www.computershare.com/DIRTT by the voting deadline of September 18, 2024 at 10:00 a.m. MDT, or in the case of adjournment or postponement, not less than 48 hours (excluding Saturdays, Sundays or holidays in Alberta) prior to the time of the adjourned or postponed Meeting or any subsequent adjournment(s) or postponement(s) thereof, and provide Computershare with the required proxyholder contact information so that Computershare may provide the proxyholder with a username via email. Without this username, proxyholders will not be able to participate or vote at the Meeting but will be able to attend as a guest.

We are holding the Meeting in a virtual format to be conducted via live audio webcast online at meetnow.global/MCX7XXF. Attending the Meeting online enables registered shareholders and duly appointed proxyholders, including non-registered shareholders who have duly appointed themselves as proxyholder, to participate at the Meeting and ask questions, all in real time. Registered shareholders and duly appointed and registered proxyholders can vote at the appropriate times during the Meeting.

Guests who are attending the Meeting virtually, including non-registered beneficial shareholders who have not duly appointed and registered themselves as proxyholder, can log in to the Meeting as set out below. Guests can listen to the Meeting and ask questions, but are not able to vote.

Log in online at meetnow.global/MCX7XXF. We recommend that you log in at least 15 minutes before the Meeting starts. Click “Login” and then enter your control number or username and password.

OR

Click “Guest” and then complete the online form.

For registered shareholders, the control number located on your proxy card or email notification is your control number for the Meeting.

For duly appointed and registered proxyholders, Computershare will provide the proxyholder with a username by e-mail after the proxy voting deadline has passed.

If you attend the Meeting online, it is important that you are connected to the Internet at all times during the Meeting in order to vote when balloting commences. It is your responsibility to ensure connectivity for the duration of the Meeting. You should allow ample time to check into the Meeting online and complete the related procedure.

If you are a registered shareholder and change your mind on how you want your Common Shares voted or you decide to attend and vote at the Meeting, or any adjournment or postponement thereof, you can revoke your proxy in any manner permitted by law, including (i) by attending the Meeting online, or any adjournment or postponement thereof, and voting your Common Shares, (ii) by depositing another form of proxy with a later date, including by instrument in writing executed by you or your attorney (duly authorized in writing) and deposited with Computershare at any time up to and including the last business day preceding the day of Meeting or any adjournment or postponement thereof at which the proxy is to be used, or with the Chair of the Meeting on the day of the Meeting, or any adjournment or postponement thereof. Attendance at the Meeting will not, by itself, revoke a proxy. If you are a non-registered shareholder, you must follow the instructions on your voting instruction form to revoke or amend any prior voting instructions.

Proxies received but marked as abstentions and broker non-votes, in each case to the extent we receive any such votes, will be included in the number of shares considered present at the Meeting for quorum purposes. If you are a non-registered shareholder holding Common Shares through an intermediary, you may instruct the intermediary that you wish to abstain from voting on a proposal at the Meeting.

A “broker non-vote” occurs when a broker who holds its client’s common shares in street name submits proxies for such common shares but indicates that it does not have authority to vote on a particular matter. Generally, this occurs when brokers have not received any instructions from their clients. Without specific instructions, Canadian brokers and their agents or nominees are prohibited from voting Common Shares for the broker’s client. Without specific instructions, U.S. brokers and their agents or nominees are prohibited from voting Common Shares for the broker’s client where a proposal is not “routine.” For the Meeting, it is expected that the Shareholder Rights Proposal will not be considered a “routine” proposal, and, therefore, U.S. brokers will be unable to exercise discretionary authority regarding any of the proposals at the Meeting for non-registered owners who have not returned voting instructions. Accordingly, we do not expect to receive any broker non-votes on any of the proposals at the Meeting.

The required vote for each of the proposals expected to be acted upon at the Meeting are described below:

Proposal No. 1 — The Shareholder Rights Proposal. The proposal to ratify, confirm and approve the Rights Agreement must be approved by the affirmative vote of a simple majority (50% plus one) of the votes cast by (i) all

shareholders, (ii) all shareholders, excluding the votes of 22NW Fund, LP (“22NW”) and WWT Opportunity #1 LLC (“WWT”), tsogether with their respective affiliates, and (iii) all Independent Shareholders (as defined in the Rights Agreement) present, either in person or by proxy, and entitled to vote (meaning that at least a simple majority of the votes cast, in each case, must be “FOR” the proposal in order for it to be approved). You may either vote “FOR” or “AGAINST” the proposal. The total votes cast with respect to this proposal will exclude abstentions and broker non-votes.

Pursuant to the Support Agreement (as defined herein), each of 22NW and WWT has agreed, on behalf of itself and each of its affiliates, to vote in favor of the Shareholder Rights Proposal in respect of all Common Shares it is entitled to vote at the Meeting. As of the Record Date, 22NW and WWT beneficially owned 57,452,441 and 53,380,753 Common Shares, respectively, representing 29.8% and 27.7% of the total outstanding Common Shares as of the Record Date. See “Proposal No. 1—Background to and Reasons for the Proposal—Support Agreement” for additional information.

Our registered shareholders, duly appointed and registered proxyholders and guests will have opportunities to submit questions throughout the Meeting. We will answer as many submitted questions relating to the proposals to be voted upon at the Meeting or about the Company generally as time permits. To ask a question, registered shareholders, duly appointed and registered proxyholders and guests may type their questions into the chat function. Additional instructions on how to ask questions will be explained during the Meeting. We encourage registered shareholders, duly appointed and registered proxyholders and guests to submit their questions in advance of the meeting to DIRTT Investor Relations at ir@dirtt.com. Following the Meeting, all questions and answers will be posted on DIRTT’s website following the Meeting (www.dirtt.com/investors). We are committed to transparent communication at the Meeting, as such, questions asked related to the business of the Meeting will not be curated and will be answered in the order received for each item of business.

This solicitation is being made by and on behalf of the Board. We will pay the cost of preparing these Proxy Materials and soliciting your vote. We also will pay the Meeting expenses. In addition, proxies may be solicited by our directors, officers and other employees over the Internet or by telephone, fax, in person or otherwise. These individuals will not receive any additional compensation for assisting in the solicitation. Other than the persons described in this Proxy Statement, no general class of employee of the Company will be employed to solicit shareholders in connection with this proxy solicitation. However, in the course of their regular duties, employees may be asked to perform tasks in furtherance of this solicitation. We may also request that intermediaries, brokerage firms, nominees, custodians and fiduciaries transmit Proxy Materials to the non-registered holders, and we will reimburse them for their reasonable out-of-pocket expenses in transmitting such materials.

The Company has retained MS as its proxy solicitation agent for the solicitation of proxies for the Meeting, or any adjournment or postponement thereof. The cost of MS’ services as proxy solicitation agent is estimated to be C$50,000, plus reasonable out-of-pocket expenses for proxy solicitation services and a success fee of C$50,000. MS may also receive additional fees from the Company for other services. MS expects that approximately 7-10 of its employees will assist in the solicitation. The parties’ engagement letter contains confidentiality, indemnification and other provisions that the Company believes are customary for this type of engagement.

The Company may utilize the Broadridge QuickVote™ service to assist Non-Objecting Beneficial Owners (“NOBOs”) with voting their Shares. NOBOs of the Company may be contacted by MS, which is soliciting proxies on behalf of the Company’s management, to obtain voting instructions over the telephone, and relaying them to Broadridge (on behalf of the shareholder’s intermediary). While representatives of MS are soliciting proxies on behalf of the Company’s management, shareholders are not required to vote in the manner recommended by the Board. The QuickVote™ system is intended to assist shareholders in exercising their votes, however, shareholders are not obligated to vote using the QuickVote™ system, and a shareholder may vote (or change or revoke their votes) at any other time and in any other applicable manner described in this Management Information Circular and Proxy Statement. Any voting instructions provided by a Shareholder will be recorded and such shareholder will receive a

letter from Broadridge (on behalf of the shareholder’s intermediary) as confirmation that their voting instructions have been accepted.

Receiving Meeting Materials as a Non-Registered Holder

The Company will not send proxy-related materials directly to non-objecting beneficial shareholders, and such materials will be delivered to non-objecting beneficial shareholders by the non-objecting beneficial shareholder’s intermediary. The Company intends to pay for the costs of an intermediary to deliver to objecting beneficial shareholders the proxy-related materials.

Background to the Proposal

In January 2024, a special committee of the Board consisting of entirely independent directors, which was established to consider strategic financing alternatives and other matters (the “Special Committee”) initiated discussions with and regarding having its two largest shareholders, 22NW and WWT, enter into standstill agreements for the benefit of the Company. Given DIRTT’s success in stabilizing operations, strengthening its construction partner network, and positioning the Company for growth at the time and in light of the completion of the Company’s C$30 million rights offering on January 9th (the “Rights Offering”) and a possible substantial issuer bid for DIRTT’s outstanding convertible debentures (which was announced on February 15, 2024 and completed on March 25, 2024), the Special Committee determined it may be beneficial to DIRTT to enter into a standstill agreement with each of 22NW and WWT to ensure the continued alignment and cohesion of its two largest shareholders with the Company’s strategy. DIRTT, 22NW and WWT had several discussions regarding whether such agreements were necessary, and the Special Committee and the Board considered the benefits and disadvantages of entering into the same.

During DIRTT’s regularly scheduled blackout period in March 2024, representatives of 22NW provided a draft standstill agreement for further consideration by the Special Committee. Discussions followed regarding entering into a standstill agreement and other governance matters among 22NW, WWT and the Special Committee. As part of such discussions, WWT indicated that it wanted to potentially increase its equity ownership in DIRTT to match the equity ownership of 22NW. WWT also indicated that it was unwilling to enter into a standstill agreement unless it was permitted to purchase such additional common shares (“WWT’s Request”). 22NW indicated that it was not amenable to WWT increasing its equity ownership in the Company. The Special Committee and the Board considered and discussed WWT’s Request and 22NW’s objection to the same. As a result, standstill agreements were not entered into with 22NW or WWT at that time.

On March 15, 2024, the Board received a shareholder requisition (the “22NW Requisition”) from 22NW requesting that the Company call a meeting of DIRTT’s shareholders to consider and vote on a non-binding advisory resolution for the Board to consider and adopt a shareholder rights plan for the Company (the “22NW SRP”). The 22NW SRP was substantially similar to the shareholder rights plan that the Company had in place from 2014 to 2020, as well as the shareholder rights plan adopted by the Board on December 7, 2021 (which plan was not approved and confirmed by the Company’s shareholders and, as such, the plan and all outstanding rights thereunder terminated and became void and of no further force and effect on April 26, 2022).

Following the receipt of the 22NW Requisition, on March 15, 2024, the Board also received a separate shareholder requisition (the “WWT Requisition” and, together with the 22NW Requisition, the “Requisitions”) from WWT requesting that the Company call a meeting of DIRTT’s shareholders to consider and vote on a non-binding advisory resolution for the Board to consider and adopt a shareholder rights plan for the Company (the “WWT SRP”). The WWT SRP was substantially similar to the 22NW SRP except, among other things, the definition of “Acquiring Person” would be raised to 33% instead of 20% (which would permit WWT and other shareholders to acquire such additional number of common shares to match the equity ownership level of 22NW).

Following receipt of the Requisitions, the Board reviewed and considered the Requisitions and the Term Sheet, including with its professional advisors. After deliberation, on March 19, 2024, DIRTT announced its intention to adopt a shareholder rights plan. On March 22, 2024 (the “Effective Date”), the Board approved and adopted the Original Shareholder Rights Plan (as defined and described below), which is in substantially similar form as the 22NW SRP, and entered into the Prior Support Agreement (as defined and described below) with 22NW. Mr. Noll voted against the Board resolution approving the Original Shareholder Rights Plan and the Board resolution approving the Prior Support Agreement. On March 18, 2024, 22NW and WWT withdrew their respective Requisitions.

In June 2024, the Special Committee reengaged in discussions with WWT about the possibility of entering into an agreement containing similar standstill arrangements as those contained in the Prior Support Agreement. WWT reiterated WWT’s Request, that it would consider entering into such a support agreement, provided it was permitted to purchase such number of additional common shares to match 22NW’s equity ownership in DIRTT. On June 17, 2024, 22NW delivered a non-binding term sheet setting forth, among other things, its proposal to have the Company

repurchase its Debentures (as defined herein) as an additional requirement for WWT executing a support and standstill agreement similar to the Prior Support Agreement. The Special Committee and the full Board (without Messrs. English and Noll) discussed the term sheet, including the Debentures repurchase. The directors discussed use of cash on hand, inclusive of proceeds from the Rights Offering to deleverage the Company’s balance sheet and improve its debt position, the increased concentration of ownership by the Company’s largest two shareholders, potential effects on trading volume in the Company’s common shares and Debentures, and other considerations. Further discussions and negotiations followed between the Special Committee, 22NW and WWT.

On July 19 2024, the Special Committee formally engaged KPMG LLP (“KPMG”) to deliver a fairness opinion related to the Debenture Repurchase (as defined and discussed below). On July 23, 2024, the Special Committee met to discuss drafts of the Fairness Opinion, WWT’s Request, the Support Agreement and the Debenture Repurchase Agreement (each as defined herein), and after such discussions made a recommendation to the Board to approve such transactions, subject to finalizing certain terms and regulatory review. On August 1, 2024 KPMG provided an opinion stating that, subject to the assumptions, limitations and qualifications therein, as of the date thereof, the consideration to be paid by the Company pursuant to the Debenture Repurchase Agreement was fair, from a financial point of view, to the Company (the “Fairness Opinion”). KPMG was paid a fixed fee for its services. On August 1, 2024, the Board met to discuss the recommendation of the Special Committee and determined that it was in the best interest of the Company to (i) enter into the Debenture Repurchase Agreement (with Mr. English abstaining from the vote), (ii) enter into the Support Agreement, (with Messrs. English and Noll abstaining from the vote), and (iii) amend the Shareholder Rights Plan (with Mr. Noll abstaining from the vote).

On August 2, 2024, the Support Agreement and the Debenture Repurchase Agreement were executed and the Company issued a press release confirming the same. For additional information, “—Support Agreements—Support Agreement” and “—Debenture Repurchase Agreement” below.

The Board also approved, effective August 2, 2024 (with Mr. Noll abstaining), an amended and restated shareholder rights plan, which amended and restated the Original Shareholder Rights Plan, with such amendment providing that WWT could purchase such number of additional common shares to match 22NW’s equity ownership in DIRTT as of the date of the amendment and such acquisition would be an “Exempt Acquisition” pursuant to the terms of the Shareholder Rights Plan (the “WWT Exempt Acquisition”). Such Shareholder Rights Plan (as defined and described below) is currently being considered pursuant to the Shareholder Rights Proposal. Otherwise, the Shareholder Rights Plan, if approved, would continue to have the effect of freezing the concentration of ownership in the Company by large shareholders who are “Grandfathered Persons” (being 22NW and WWT), subject to the WWT Exempt Acquisition and certain exceptions as provided in the Rights Agreement.

As of August 2, 2024, 22NW held 29.8% and WWT held 27.7% of the issued and outstanding common shares of the Company, respectively. For more information, see “Security Ownership of Certain Beneficial Owners and Management.”

Support Agreements

Prior Support Agreement

The Company delivered and entered into a binding commitment (the “Term Sheet”), effective March 17, 2024, with 22NW to enter into a subsequent definitive support and standstill agreement. On March 22, 2024, the Board approved (with one Board member, Mr. Noll, dissenting), and the Company entered into, a Support and Standstill Agreement, dated March 22, 2024, by and between the Company and 22NW (the “Prior Support Agreement”). Pursuant to the Prior Support Agreement, the Company agreed to nominate Aron English (or a replacement director to be identified by 22NW) for election as a director at each of the annual general meeting of the Company in 2024 and 2025 (the “2024 Meeting” and “2025 Meeting,” respectively), subject to 22NW continuing to beneficially own a number of Common Shares in excess of certain thresholds set forth in the Prior Support Agreement.

Additionally, until the day following the 2025 Meeting, 22NW agreed to, among other things, (i) vote all of its Common Shares in favor of the recommendations of the Board on director election proposals and (ii) comply with certain customary standstill provisions, in each case subject to certain exceptions.

The Prior Support Agreement was superseded and replaced in its entirety by the Support Agreement and, accordingly, is of no further force or effect as of the date of the Support Agreement.

Support and Standstill Agreement

On August 1, 2024, the Board (with Messrs. English and Noll abstaining) approved a Support and Standstill Agreement, effective August 2, 2024, by and among the Company, 22NW and WWT (the “Support Agreement”).

Pursuant to the Support Agreement, the Company agreed to nominate each of Aron English (or a replacement director to be identified by 22NW) and Shaun Noll (or a replacement director to be identified by WWT) for election as a director at each of the 2025 Meeting and the annual general meetings of shareholders of the Company in 2026 (the “2026 Meeting”). The Company’s obligation to nominate each of Aron English and Shaun Noll is subject to 22NW and WWT (together with their affiliates), respectively, continuing to beneficially own, or exercising control or direction over, at least the lesser of (i) 20% of the then issued and outstanding Common Shares and (ii) 38,593,529 Common Shares, in each case, subject to adjustment for stock splits, reclassifications, combinations and similar adjustments.

Further, the Support Agreement provides that at any time prior to the termination of the Support Agreement, WWT may increase the number of Common Shares it beneficially owns, or exercises direction or control over, through market purchases up to and including 57,447,988 shares (the “Capped Amount”), being the number of Common Shares beneficially held by 22NW on the date of the Support Agreement.

Until the termination of the Support Agreement, each of 22NW and WWT agreed that, among other things, it will:

The Support Agreement also contains certain mutual non-disparagement provisions and customary representations and warranties.

The Support Agreement will terminate upon the earlier of the occurrence of (i) if the Debenture Repurchase is not completed within 30 days from the date of the Support Agreement; (ii) the Board does not approve the Shareholder Rights Plan; (iii) the Meeting is not held on or before January 31, 2025, unless the Meeting is not held prior to such date as a result of any Regulations (as defined in the Support Agreement) or any action or inaction by 22NW or WWT; (iv) any material breach of the Support Agreement by the parties thereto (subject to customary notice and cure provisions), in which case only the non-breaching parties may terminate the Support Agreement (v) the date which is 90 days following the 2026 Meeting. The termination date cannot be extended 90 days or more past the date of the 2026 Meeting without the consent of the Toronto Stock Exchange (“TSX”).

Convertible Debenture Repurchase Agreement

On August 2, 2024, concurrently with the Company’s entry into the Support Agreement, the Company entered into a Convertible Debenture Repurchase Agreement with 22NW (the “Debenture Repurchase Agreement”), pursuant to which 22NW agreed to sell, and the Company agreed to purchase for cancellation an aggregate of (i) C$18,915,000 principal amount of the Company’s outstanding 6.00% convertible debentures due January 31, 2026 (the “January Debentures”) at a purchase price of C$684.58 per C$1,000 principal amount of January Debentures and (ii) C$13,638,000 principal amount of the Company’s outstanding 6.25% convertible debentures due December 31, 2026 (the “December Debentures” and together with the January Debentures, the “Debentures”) at a purchase price of C$665.64 per C$1,000 principal amount of December Debentures, for an aggregate purchase price of C$22,104,591.45, inclusive of a cash payment for all accrued and unpaid interest up to, but excluding, the date on which such Debentures are purchased by the Company (the “Debenture Repurchase”).

Pursuant to the Debenture Repurchase Agreement, the purchase price of each series of Debentures was calculated as: (i) a 4% discount to the average trading price of the applicable series of Debentures on the Toronto Stock Exchange for the 20 trading days immediately preceding August 2, 2024 plus (ii) all accrued and unpaid interest up to, but excluding, August 2, 2024. 22NW is the Company’s largest shareholder and Aron English, a director of the Company, is the Portfolio Manager of 22NW.

The Debenture Repurchase closed on August 2, 2024 and, as a result, C$16,642,000 principal amount of the January Debentures and C$15,587,000 principal amount of the December Debentures remain outstanding, and 22NW no longer holds any Debentures. The Company funded the Debenture Repurchase with cash on hand.

The Board considered and evaluated the recommendation of the Special Committee, the Fairness Opinion, discussions with its external advisors, and the funds available to the Company to finance the Debenture Repurchase, among other factors, and determined that the Debenture Repurchase was in the best interest of the Company. Mr. English recused himself from all Board meetings, or portions thereof, as applicable, at which the Debenture Repurchase was considered and abstained from voting on the Debenture Repurchase.

Reasons for the Proposal

As discussed above, in light of the share ownership of the Company as a result of the completion of the Rights Offering, the Special Committee advised the Board that it may be prudent for the Company to take certain steps to limit the opportunities available for creeping take-over bids and allow the Company to focus on the business and the positive progress experienced in the recent period.

On March 22, 2024, the Board approved (with one Board member, Mr. Noll, dissenting) and adopted a shareholder rights plan agreement by and between the Company and Computershare Trust Company of Canada, as rights agent (the “Original Rights Agreement”), which provided for a shareholder rights plan (the “Original Shareholder Rights Plan”). In connection therewith, one right (a “Right”) was issued and attached to each Common Share outstanding and held of record at the close of business on April 1, 2024 (the “Record Time”) as set forth in the Original Rights Agreement and as confirmed in the Rights Agreement. Subsequently, on August 1, 2024, the Board approved,

effective August 2, 2024 (with Mr. Noll abstaining), an amended and restated shareholder rights plan agreement by and between the Company and Computershare Trust Company of Canada, as rights agent (as amended and restated, the “Rights Agreement”), which amended and restated the Original Rights Agreement and provides for an amended and restated shareholder rights plan (as amended and restated, the “Shareholder Rights Plan”), which amended and restated the Original Shareholder Rights Plan.

Other than the WWT Exempt Acquisition, the Shareholder Rights Plan is consistent with the Original Shareholder Rights Plan and consistent with the shareholder rights plan that the Company had in place from 2014 to 2020 and the shareholder rights plan adopted by the Board on December 7, 2021, and is similar to shareholder rights plans adopted by other Canadian public companies. The Rights Agreement was adopted to help ensure that all shareholders of the Company are treated fairly and equally in connection with any unsolicited take-over bid or other acquisition of control of the Company (including by way of a “creeping” take-over bid). The Rights Agreement was not adopted in response to any specific proposal to acquire control of the Company, and the Board is not aware of any pending or potential take-over bid for the Company.

In accordance with the rule of the Toronto Stock Exchange, the adoption of the Rights Agreement must be ratified, confirmed and approved by the shareholders at the Meeting to continue to have effect after the Meeting and at every third annual meeting of shareholders thereafter.

Purpose of the Shareholder Rights Plan

The objective of the Shareholder Rights Plan is to ensure that all shareholders of the Company are treated equally and fairly in connection with any unsolicited take-over bid or other acquisition of control of the Company. The Shareholder Rights Plan is intended to, among other things: (i) prevent, to the extent possible, a unsolicited or hostile acquiror from obtaining control through a creeping take-over of the Company (i.e., the acquisition of effective control through a number of purchases exempt from the Canadian take-over bid rules over time), private acquisitions using the private agreement exemption from the Canadian take-over bid rules or other transactions exempt from the take-over bid rules under applicable Canadian securities laws; and (ii) protect against unsolicited or hostile acquirors entering into auction-inhibiting “hard” lock-up agreements whereby existing shareholders commit to tender their shares to a take-over bid, that are either irrevocable or revocable but subject to preclusive termination conditions. The Shareholder Rights Plan also has the effect of freezing the concentration of ownership in the Company by large shareholders who are “Grandfathered Persons,” including 22NW and WWT, subject to the WWT Exempt Acquisition and certain other exceptions. See “—Summary of the Rights Agreement” for more information.

The Shareholder Rights Plan does not prevent take-overs; rather it encourages potential acquirors of control to make take-over bids by means of a Permitted Bid (as defined below), which shareholders may tender to regardless of the acceptability of the bid to the Board or to approach the Board to negotiate a mutually acceptable transaction. The Shareholder Rights Plan does not diminish or detract from the duty of the Board to act honestly, in good faith and in the best interests of the Company and the shareholders, or to consider on that basis any take-over bid that is made; nor does the Shareholder Rights Plan alter the proxy mechanism to change the Board, create dilution on the initial issue of the Rights (as defined below), or change the way in which the Common Shares trade.

The Shareholder Rights Plan attempts to address certain concerns that exist in the provisions of current legislation governing take-over bids in Canada. Under current securities legislation, an offeror may obtain control or effective control of a corporation without paying full value, without obtaining shareholder approval and without treating all shareholders equally. For example, an acquiror could acquire blocks of shares by private agreement from one or a small group of shareholders at a premium to market price, which premium is not shared by the other shareholders. In addition, a person could slowly accumulate shares through stock exchange acquisitions which may result, over time, in an acquisition of control or effective control without paying a control premium or fair sharing of any control premium among shareholders. Under the Shareholder Rights Plan, if it is to qualify as a Permitted Bid, any offer to acquire 20% or more of the Common Shares must be made to all shareholders. As set forth in detail below, the Shareholder Rights Plan discourages the conduct it seeks to prohibit as outlined above by creating the potential that any Common Shares which may be acquired or held by a take-over acquiror will be significantly diluted if not acquired in a manner permitted by the Shareholder Rights Plan. The potential for significant dilution to the holdings of such an acquiror can occur as the Shareholder Rights Plan provides that all shareholders who are not related to the acquiror will be entitled to exercise rights issued to them under the Shareholder Rights Plan and to acquire Common

Shares at a substantial discount to prevailing market prices; however, the acquiror and the persons related to the acquiror will not be entitled to exercise any Rights under the Rights Agreement.

Shareholder Approval

At the Meeting, shareholders will be asked to pass the following ordinary resolution ratifying, confirming and approving the Rights Agreement, subject to such amendments, variations or additions as may be approved at the Meeting:

“BE IT RESOLVED THAT:

If shareholder ratification, confirmation and approval is obtained at the Meeting, the Rights Agreement will remain in effect and will require reconfirmation and reapproval by shareholders of the Company at the 2027 annual meeting of shareholders, and at every third annual meeting thereafter. If shareholder ratification, confirmation and approval is not obtained at the Meeting, the Rights Agreement and all Rights issued thereunder will terminate and cease to be effective at that time.

TSX Approval

The TSX has conditionally accepted the Shareholder Rights Plan. Final acceptance of the Shareholder Rights Plan by the TSX is subject to, among other customary conditions, the Rights Agreement being ratified by the affirmative vote of a simple majority (50% plus one) of the votes cast by (i) all shareholders and (ii) all shareholders, excluding the votes of 22NW and WWT, together with their respective affiliates. As of the Effective Date, each of 22NW and WWT Beneficially Own (as defined in the Rights Agreement) more than 20% of the outstanding Voting Shares (as defined in the Rights Agreement) and are considered “Grandfathered Persons” for the purposes of the Shareholder Rights Plan. For more information see “Summary of the Rights Agreement – Separation of Rights” below.

Recommendation of the Board

The Board unanimously recommends that shareholders vote “FOR” the foregoing resolution.

The Board believes that the Shareholder Rights Plan is consistent with current Canadian corporate best practices and institutional investor guidelines. The Shareholder Rights Plan is not intended to prevent a take-over of the Company. The Shareholder Rights Plan is not being adopted in response to any specific proposal to acquire control of the Company, and the Board is not aware of any pending or threatened take-over bid for the Company.

Summary of the Rights Agreement

The following summary of terms of the Rights Agreement is qualified in its entirety by reference to the text of the Rights Agreement attached as Appendix A. A copy of the Rights Agreement is also available on SEDAR+ at http://www.sedarplus.ca and EDGAR at http://www.sec.gov.

The Rights Agreement must be ratified, confirmed and approved at the Meeting to remain in effect, and, if so ratified, will expire on the date of the annual meeting of shareholders to be held in 2027, unless it is ratified,

confirmed and approved at such meeting, subject to earlier termination or expiration of the Rights as set out in the Rights Agreement.

The Rights Agreement provides that one Right was issued by the Company in respect of each Voting Share outstanding as of the Record Time. “Voting Shares” include the Common Shares and any other shares in the capital of the Company entitled to vote generally in the election of all directors of the Company. One Right will also be issued for each additional Voting Share issued after the Record Time and prior to the earlier of the Separation Time (as defined below) subject to the earlier termination or expiration of the Rights as set out in the Rights Agreement.

As of the date hereof, the only Voting Shares outstanding are the Common Shares. The issuance of the Rights is not dilutive and will not affect reported earnings or cash flow per share until the Rights separate from the underlying Common Shares and become exercisable or until the exercise of the Rights. The issuance of the Rights will not change the manner in which shareholders currently trade their Common Shares.

Prior to the Separation Time, the Rights will be evidenced by a legend imprinted on certificates for Common Shares issued from and after the Record Time. Rights are also attached to Common Shares outstanding as of the Record Time, although share certificates issued prior to such time will not bear such a legend. Shareholders are not required to return their certificates in order to have the benefit of the Rights. Prior to the Separation Time, Rights will trade together with the Common Shares and will not be exercisable or transferable separately from the Common Shares. From and after the Separation Time, the Rights will become exercisable, will be evidenced by Rights Certificates (as defined below) and will be transferable separately from the Common Shares.

The Rights will become exercisable and begin to trade separately from the associated Common Shares at the “Separation Time” which is generally (subject to the ability of the Board to defer the Separation Time) the close of business on the tenth trading day after the earliest to occur of:

The definition of “Acquiring Person” will exclude, among other things, “Grandfathered Persons.” A “Grandfathered Person” is a person who is the Beneficial Owner of 20% or more of the outstanding Voting Shares determined as at the Effective Date, provided, however, that this exception shall not be applicable to a Grandfathered Person if, after the Effective Date, such Grandfathered Person becomes the Beneficial Owner of any additional Voting Shares that increases its Beneficial Ownership of Voting Shares by more than 1% of the number of Voting Shares outstanding, other than through one of circumstances described in clauses (i) through (v) in paragraph 1 above. Additionally, WWT is permitted to purchase up to and including the Capped Amount (being the number of Common Shares

beneficially held by 22NW on the date of the Shareholder Rights Plan) prior to the 90th day following the 2026 Meeting, and such acquisition would be an “Exempt Acquisition” pursuant to the terms of the Shareholder Rights Plan. A Grandfathered Person will also cease to be a Grandfathered Person if such person ceases to Beneficially Own 20% or more of the then outstanding Voting Shares at any time after the Effective Date.

As soon as practicable following the Separation Time, separate certificates evidencing Rights (“Rights Certificates”) will be mailed to the holders of record of the Voting Shares as of the Separation Time and the Rights Certificates alone will evidence the Rights. Unless the context otherwise requires, the term “Rights Certificate” shall include any other document or written acknowledgement that is evidence of registered ownership of the applicable securities as may be adopted from time to time by the Company, including without limitation a direct registration advice.

Prior to the Separation Time, the price at which a holder may purchase the securities issuable upon exercise of one whole Right, subject to adjustment in accordance with the terms of the Rights Agreement, shall be, until the Separation Time, an amount equal to three times the Market Price, from time to time (the “Exercise Price”). From and after the Separation Time, each Right entitles the holder thereof to purchase one Common Share at an initial Exercise Price equal to three times the market price at the Separation Time (provided that a Flip-in Event (as defined below) has not occurred). The “Market Price” is defined as the average of the daily closing prices per share of such securities on each of the 20 consecutive trading days through and including the trading day immediately preceding the Separation Time. Following a transaction which results in a person becoming an Acquiring Person (a “Flip-in Event”), the Rights entitle the holder thereof to receive, upon exercise, such number of Common Shares which have an aggregate market value (as of the date of the Flip-in Event) equal to twice the then Exercise Price. In such event, however, any Rights beneficially owned by an Acquiring Person (including affiliates, associates and other acting jointly or in concert therewith), or a transferee of any such person, will be null and void. A Flip-in Event does not include acquisitions approved by the Board or acquisitions pursuant to a Permitted Bid or Competing Permitted Bid (as defined below).

A bidder can make a take-over bid and acquire Voting Shares without triggering a Flip-in Event under the Rights Agreement if the take-over bid qualifies as a Permitted Bid. The requirements of a “Permitted Bid” include the following:

The Rights Agreement also allows for a competing Permitted Bid (a “Competing Permitted Bid”) to be made while a Permitted Bid is in existence. A Competing Permitted Bid must satisfy all of the requirements of a Permitted Bid except that it must remain open for acceptance until the last day on which the take-over bid must be open for acceptance after the date of that take-over bid under applicable Canadian provincial securities legislation.

A person will not become an Acquiring Person by virtue of having entered into an agreement (a “Permitted Lock-Up Agreement”) with a shareholder whereby the shareholder agrees to deposit or tender Voting Shares to a take-over bid (the “Lock-Up Bid”) made by such person, provided that the agreement meets certain requirements including:

Redemption and Waiver

If a potential offeror does not desire to make a Permitted Bid, it can negotiate with, and obtain the prior approval of, the Board to make a formal take-over bid by way of a take-over bid circular sent to all holders of Voting Shares on terms which the Board considers fair to all shareholders. In such circumstances, the Board may waive the application of the Rights Agreement thereby allowing such bid to proceed without dilution to the offeror. Any waiver of the application of the Rights Agreement in respect of a particular formal take-over bid shall also constitute a waiver of any other formal take-over bid which is made by means of a take-over bid circular to all holders of voting shares while the initial take-over bid is outstanding. The Board may also waive the application of the Rights Agreement in respect of a particular Flip-in Event that has occurred through inadvertence, provided that the Acquiring Person that inadvertently triggered such Flip-in Event reduces its beneficial holdings to less than 20% of the outstanding Voting Shares within 14 days or such earlier or later date as may be specified by the Board. With the prior consent of the holders of Voting Shares, the Board may, prior to the occurrence of a Flip-in Event that would occur by reason of an acquisition of Voting Shares otherwise than pursuant to the foregoing, waive the application of the Rights Agreement to such Flip-in Event.

The Board may, with the prior consent of the holders of Voting Shares, at any time prior to the occurrence of a Flip-in Event, elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $0.00001 per Right. Rights are deemed to be redeemed following completion of a Permitted Bid, a Competing Permitted Bid or a take-over bid in respect of which the Board has waived the application of the Rights Agreement.

Protection Against Dilution

The Exercise Price, the number and nature of securities which may be purchased upon the exercise of Rights and the number of Rights outstanding are subject to adjustment from time to time to prevent dilution in the event of stock dividends, subdivisions, consolidations, reclassifications or other changes in the outstanding Common Shares, pro rata distributions to holders of Common Shares and other circumstances where adjustments are required to appropriately protect the interests of the holders of Rights.

Exemptions for Investment Advisors

Investment advisors (for client accounts), trust companies (acting in their capacity as trustees or administrators), statutory bodies whose business includes the management of funds (for employee benefit plans, pension plans, or insurance plans of various public bodies) and administrators or trustees of registered pension plans or funds acquiring greater than 20% of the Voting Shares are exempted from triggering a Flip-in Event, provided they are not making, either alone or jointly or in concert with any other person, a take-over bid.

Duties of the Board

The adoption of the Rights Agreement will not in any way lessen or affect the duty of the Board to act honestly and in good faith with a view to the best interests of the Company. The Board, when a take-over bid or similar offer is made, will continue to have the duty and power to take such actions and make such recommendations to shareholders as are considered appropriate.

Amendment

The Company may, with the prior approval of shareholders (or the holders of Rights if the Separation Time has occurred), supplement, amend, vary or delete any of the provisions of the Rights Agreement. Any such amendment shall be effective from the date it is adopted by the Board, until it is confirmed or rejected by the shareholders. If such amendment is rejected by the shareholders, then such amendment shall cease to be effective from and after the termination of the meeting. The Company may make amendments to the Rights Agreement at any time without the prior approval of shareholders (or the holders of Rights if the Separation Time has occurred) to correct any clerical or typographical error or, subject to confirmation at the next meeting of shareholders, make amendments which are required to maintain the validity of the Rights Agreement due to changes in any applicable legislation, regulations or rules.

The Board unanimously recommends that the shareholders vote “FOR” the ratification, confirmation and approval of the Rights Agreement.

Other than as described below, management is not aware of any material interest, direct or indirect of any informed person of the Company, or any of associate or affiliate of an informed person, in any transaction since the commencement of the Company’s most recently completed financial year, or in any proposed transaction, that has materially affected or would materially affect the Company or any of its affiliates or subsidiaries.

On March 15, 2023, the Company entered into a debt settlement agreement with 22NW, of which Aron English, one of the Company’s directors, is the Portfolio Manager (the “Debt Settlement Agreement”). Pursuant to the Debt Settlement Agreement, the Company agreed to reimburse 22NW for the debt related to the 2022 annual and special meeting of the Company (the “2022 Meeting”), being US$1,559,898 (the “Debt”), in exchange for a release of (i) the Company from any claims for reimbursement of expenses incurred by 22NW in relation to the 2022 Meeting; and (ii) the Company’s present and future directors, officers and employees of and from all actions, causes of action, suits, debts, dues, controversies, accounts, bonds, bills, covenants, contracts, agreements, judgments, claims, costs, obligations, charges, security interests and demands whatsoever, in law or in equity, which may be related to any claims 22NW now has, ever had or hereafter can, shall or may have against the Company for or by reason of or in any way arising, directly or indirectly, out of the 2022 Meeting.

Pursuant to the Debt Settlement Agreement, the Company agreed to repay the Debt by either, or a combination of, (a) a cash payment or (b) the issuance of equity securities of the Company to 22NW.

In connection with the entry into the Debt Settlement Agreement, on March 15, 2023, the Company entered into an agreement, pursuant to which the Company agreed to repay the Debt with the issuance of 3,899,745 Common Shares to 22NW at a deemed price of C$0.40 per Common Share, subject to shareholder approval at the Meeting. At the Annual General Meeting on May 30, 2023, shareholders voted to approve the issuance of Common Shares,

During 2023, C$18.9 million and C$13.6 million principal amount the January Debentures and the December Debentures, respectively, were acquired by 22NW Fund and Aron English (collectively, the “22NW Group”). Interest accrued on the Debentures owned by the 22NW Group for the year ended December 31, 2023 was C$0.4 million and interest expense paid was C$0.5 million. Interest on the Debentures held by the 22NW Group is earned on terms applicable to all Debenture holders.

On November 21, 2023, the Company announced a C$30,000,000 rights offering (the “Rights Offering”). Pursuant to the Rights Offering, the Company distributed at no charge to holders of the Common Shares of record as of the close of business on December 12, 2023, transferable subscription rights (“Rights”) to purchase up to an aggregate of up to approximately 85,714,285 Common Shares. In connection with the Rights Offering, the Company entered into a standby purchase agreement with 22NW Fund and 726 BC LLC and 726 BF LLC (together “726”) dated November 20, 2023 (the “Standby Purchase Agreement”), pursuant to which each of 22NW and 726, or their permitted assigns (collectively and including WWT, to which 726 transferred their entire holdings on December 1, 2023, the “Standby Purchasers”) agreed to exercise their basic subscription privilege under the Rights Offering in full and, in addition thereto, to collectively purchase all Common Shares not subscribed for by holders under the basic subscription privilege or additional subscription privilege (the “Standby Shares”), so that at least 85,714,285 Common Shares would be sold and the Company would realize gross proceeds of C$30,000,000 under the Rights Offering (subject to adjustments for rounding and inclusive of the obligations under the Standby Purchase Agreement). Pursuant to the Rights Offering, Aron English and 22NW Fund collectively acquired 29,767,055 Common Shares for total consideration of C$10,418,469.25, WWT and Shaun Noll, a director of the Company and Managing Member of WWT, collectively acquired 31,185,364 Common Shares for total consideration of C$10,914,877.40, and all other directors and executive officers acquired 839,884 Common Shares for total consideration of C$293,959.40.

Under the Standby Purchase Agreement, the Company agreed to reimburse the Standby Purchasers for reasonable legal and other expenses in connection with the Standby Purchase Agreement, up to a maximum of C$30,000 per Standby Purchaser.

On August 2, 2024, the Company entered into the Support Agreement with 22NW and WWT, which, among other things, replaced the Prior Support Agreement entered into with 22NW. For more information regarding the Support

Agreement, see “Proposal No. 1 – The Shareholder Rights Plan – Background to and Reasons for the Proposal – Support Agreement.”

On August 2, 2024, the Company entered into the Debenture Repurchase Agreement with 22NW and completed the repurchase of the Debentures for an aggregate price of C$22,104,591.45 (inclusive of all accrued and unpaid interest up to, but excluding, the repurchase date). For more information regarding the Debenture Repurchase Agreement, see “Proposal No. 1 – The Shareholder Rights Plan – Background to and Reasons for the Proposal – Debenture Repurchase Agreement.”

Management is not aware of any other business to come before the Meeting, or any adjournment or postponement thereof, other than as set forth herein. If any other business properly comes before the Meeting, or any adjournment or postponement thereof, to the extent permitted by Rule 14a-4(c) of the Exchange Act, it is the intention of the persons named in the proxy card to vote the Common Shares represented thereby in accordance with their best judgment on such matter. In order for any shareholder to nominate a candidate or to submit a proposal for other business to be acted upon at a given annual meeting, he or she must provide timely written notice to our Corporate Secretary in the form prescribed by our current by-laws, as described under “Shareholder Proposals.”

The SEC has adopted rules that permit companies and intermediaries to satisfy the delivery requirements for the Proxy Materials with respect to two or more shareholders sharing the same address by delivering a single set of the Proxy Materials addressed to those shareholders. This process, which is commonly referred to as “householding,” is intended to provide extra convenience for shareholders and cost savings for companies.

A number of brokers with account holders who are shareholders may be “householding” our Proxy Materials. A single set of Proxy Materials will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from one or more of the affected shareholders. If you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of materials, please notify the Company or Broadridge Financial Solutions at the address or telephone number listed below, and the Company will then promptly deliver such additional materials to you. Shareholders who have multiple accounts in their names or who share an address with other shareholders can request “householding” and authorize your broker to discontinue mailings of multiple annual reports and management information circular and proxy statements by contacting the same addresses or telephone numbers below:

The Company is subject both to the rules of the SEC under the Exchange Act and the provisions of the Business Corporations Act (Alberta) (the “ABCA”) with respect to shareholder proposals. As set out under the ABCA and in the rules of the SEC under the Exchange Act, simply submitting a shareholder proposal does not guarantee its inclusion in, because compliance with applicable law is a prerequisite for inclusion.

A shareholder proposal submitted pursuant to the rules of the SEC under Rule 14a-8 of the Exchange Act for inclusion in a management information circular and proxy statement distributed to shareholders prior to the 2025 annual meeting of shareholders of the Company (other than in respect of the nomination of directors) must be received by the Company no later than November 28, 2024 and must comply with the requirements of Rule 14a-8 of the Exchange Act.

Any shareholder who intends to solicit proxies in support of any director nominee other than the Company’s nominees must also comply with the notice and content requirements of Rule 14a-19 under the Exchange Act (known as the universal proxy rule) in addition to the deadlines in the advance notice provisions of our current by-laws, described in further detail below. Thus, if a shareholder intends to solicit proxies in support of any director nominees submitted under the advance notice provisions of our current by-laws for the 2025 annual meeting of shareholders, then such shareholder must also provide proper written notice postmarked or transmitted electronically to the Company at its principal executive office that sets forth all of the information required by Rule 14a-19 under the Exchange Act no later than 60 days before the anniversary of the 2024 annual meeting (that is, March 10, 2025); provided, however, that if the date of the 2025 annual meeting is more than 30 days before or after the anniversary of the 2024 annual meeting of shareholders, to be properly brought, the notice by the shareholder must be received by the later of 60 calendar days prior to the date of the 2025 annual meeting or the 10th calendar day following the day on which public announcement of the date of the 2025 annual meeting is first made by the Company.

Under the advance notice provisions of our current by-laws, a shareholder who intends to nominate a director for election at the 2025 annual meeting of shareholders must give notice of such nomination (a “Nomination Notice”) in proper form to the Chair of the Board not less than 30 days before the 2025 annual meeting, unless such meeting is called for a date that is less than 50 days following the date on which the first public filing or announcement of the date of such meeting was made, in which case a Nomination Notice must be given not later than the close of business on the 10th day following the date of such public filing or announcement; except that, if “notice-and-access” pursuant to and in accordance with applicable securities laws is used for delivery of proxy related materials in respect of the 2025 annual meeting and the date on which the first public filing or announcement of the date of such meeting was made in respect of such meeting is not less than 50 days prior to the date of the meeting, the Nomination Notice must be received not less than 40 days before the date of the applicable meeting. Our current by-laws include the full text of the advance notice provisions. These provisions are generally intended to provide shareholders, directors and management of the Company with a clear framework for nominating directors. These provisions set deadlines, as outlined above, for a shareholder to notify the Company of his, her or its intention to nominate one or more directors at a shareholders’ meeting, and explains the information that must be included with the notice for it to be valid.

Our current by-laws are available on our website at www.dirtt.com, on EDGAR at www.sec.gov and on SEDAR+ at www.sedarplus.ca.

The ABCA permits certain eligible shareholders and beneficial owners of shares to submit shareholder proposals to the Company, which proposals may be included in the Company’s management information circular and proxy statement. To be considered for inclusion in the management information circular and proxy statement for an annual meeting of shareholders of the Company, any such shareholder proposal under the ABCA must be received by the Company at least 90 days before the anniversary date of the last annual meeting of shareholders, or February 8, 2025 for inclusion in the management information circular and proxy statement distributed to shareholders prior to the 2025 annual meeting of shareholders of the Company.

Written requests for inclusion of a shareholder proposal pursuant to the rules of the SEC under the Exchange Act or pursuant to the ABCA should be addressed to our Corporate Secretary at our principal executive offices as follows:

AMENDED aND RESTATED shareholder rights plan AGREEMENT

THIS AMENDED AND RESTATED SHAREHOLDER RIGHTS PLAN AGREEMENT is made as of August 2, 2024 between DIRTT Environmental Solutions Ltd. (the "Corporation"), a corporation amalgamated under the laws of the Province of Alberta, and Computershare Trust Company of Canada, a trust company continued under the laws of Canada and registered to carry on business in all provinces of Canada (the "Rights Agent") and amends and restates the Original Agreement (as defined below).

WHEREAS the Corporation and the Rights Agent entered into a shareholder rights plan agreement as of March 22, 2024 (the "Original Agreement") in respect of a shareholder rights plan (the "Original Rights Plan");

AND WHEREAS the Board of Directors (as hereinafter defined), in the exercise of its fiduciary duties to the Corporation, determined that it is advisable for the Corporation to amend and restate the Original Agreement in its entirety on the terms and conditions and in the form of this Agreement (as hereinafter defined), and to effect the continued distribution of Rights (as hereinafter defined) under the Original Rights Plan as amended and restated herein to prevent, to the extent possible, a creeping takeover of the Corporation and to ensure, to the extent possible, the fair treatment of all shareholders in connection with any take-over bid for the securities of the Corporation, and to ensure that the Board of Directors is provided with sufficient time to evaluate unsolicited take-over bids and to explore and develop alternatives to maximize shareholder value;

AND WHEREAS in order to amend and restate the Original Agreement in its entirety on the terms and conditions and in the form of this Agreement (as hereinafter defined), the Board of Directors has:

AND WHEREAS each Right entitles the holder thereof, after the Separation Time, to purchase securities of the Corporation pursuant to the terms and subject to the conditions set forth herein;

AND WHEREAS the Corporation desires to confirm the appointment of the Rights Agent to act on behalf of the Corporation and the holders of Rights, and the Rights Agent is willing to continue to so act, in connection with the issuance, transfer, exchange and replacement of Rights Certificates, the exercise of Rights and other matters referred to herein.

NOW THEREFORE in consideration of the premises and the respective covenants and agreements set forth herein, and subject to such covenants and agreements, the parties hereby agree as follows:

For purposes of this Agreement, the following terms have the meanings indicated:

provided, however, that if a Person becomes the Beneficial Owner of 20% or more of the outstanding Voting Shares by reason of one or any combination of the operation of Paragraphs (A), (B), (C), (D) or (E) above and such Person's Beneficial Ownership of Voting Shares thereafter increases by more than 1% of the number of Voting Shares outstanding (other than pursuant to one of a Voting Share Reduction, a Permitted Bid Acquisition, an Exempt Acquisition, a Pro Rata Acquisition or a Convertible Security Acquisition or any combination thereof), then as of the date such Person becomes the Beneficial Owner of such additional Voting Shares, such Person shall become an "Acquiring Person";

provided, however, that a Person shall not be deemed the "Beneficial Owner" of, or to have "Beneficial Ownership" of, or to "Beneficially Own", any security:

provided, in any of the above cases, that the Investment Manager, the Trust Company, the Statutory Body, the Administrator or the Plan, as the case may be, is not then making and has not then announced an intention to make a Take-over Bid (other than an Offer to Acquire Voting Shares or other securities by means of a distribution by the Corporation or by means of ordinary market transactions (including prearranged trades) executed through the facilities of a stock exchange or organized over-the-counter market), alone or by acting jointly or in concert with any other Person;

provided that, should a Competing Permitted Bid cease to be a Competing Permitted Bid because it ceases to meet any or all of the requirements mentioned above prior to the time it expires (after giving effect to any extension) or is withdrawn, then any acquisition of Voting Shares made pursuant to such Competing Permitted Bid, including any acquisition of Voting Shares made prior to such time, shall not be a Permitted Bid Acquisition.

and "controls", "controlling" and "under common control with" shall be interpreted accordingly;

be applied to the purchase from the Corporation of Voting Shares;

provided, however, that if for any reason none of such prices is available on such day, the closing price per share of such securities on such date means the fair value per share of such securities on such date as determined by a nationally or internationally recognized investment dealer or investment banker with respect to the fair value per share of such securities. The Market Price shall be expressed in Canadian dollars and, if initially determined in respect of any day forming part of the 20 consecutive Trading Day period in question in United States dollars, such amount shall be translated into Canadian dollars on such date at the Canadian Dollar Equivalent thereof;

or any combination thereof, and the Person accepting an offer to sell shall be deemed to be making an Offer to Acquire to the Person that made the offer to sell;

For purposes of this Agreement, (A) should a Take-over Bid which qualified as a Permitted Bid cease to be a Permitted Bid because it ceases to meet any or all of the requirements mentioned above prior to the time it expires (after giving effect to any extension) or is withdrawn, any acquisition of Voting Shares made pursuant to such Take-over Bid shall not be a Permitted Bid Acquisition and (B) the term "Permitted Bid" shall include a Competing Permitted Bid;

and, for greater clarity, the agreement may contain a right of first refusal or require a period of delay to give such Person an opportunity to at least match a higher price or value in another Take-over Bid or transaction or other similar limitation on a Locked-up Person's right to withdraw Voting Shares from the agreement, so long as the limitation does not preclude the exercise by the Locked-up Person of the right to withdraw Voting Shares during the period of the other Take-over Bid or transaction; and

shall be payable by such Locked-Up Person pursuant to the agreement if the Locked-Up Person fails to deposit or tender Voting Shares to the Lock- Up Bid, withdraws Voting Shares previously tendered thereto or supports another transaction;

provided, however, that such Person does not thereby acquire a greater percentage of such Voting Shares or of Convertible Securities so offered than such Person's percentage of Voting Shares Beneficially Owned immediately prior to such acquisition;

or such later time as may be determined by the Board of Directors, provided that, if any Take-over Bid referred to in Subsection 1.1(tt)(ii) above expires, is not made, is cancelled, terminated or otherwise withdrawn prior to the Separation Time, such Take-over Bid shall be deemed, for the purposes of this definition, never to have been commenced, made or announced and further provided that if the Board of Directors determines, pursuant to Section 5.1, to waive the application of Section 3.1 to a Flip-in Event, then the Separation Time in respect of such Flip-in Event shall be deemed never to have occurred and further provided that if the foregoing results in the Separation Time being prior to the Record Time, the Separation Time shall be the Record Time;

All sums of money which are referred to in this Agreement are expressed in lawful money of Canada, unless otherwise specified.

Wherever the context will require, terms (including defined terms) used herein importing the singular number only shall include the plural and vice versa and words importing any one gender shall include all others.

The division of this Agreement into Articles, Sections, Subsections, Paragraphs, Subparagraphs or other portions hereof and the insertion of headings, subheadings and a table of contents are for convenience of reference only and shall not affect the construction or interpretation of this Agreement.

Unless the context otherwise requires, any reference to a specific section, subsection, clause or rule of any act or regulation shall be deemed to refer to the same as it may be amended, reenacted or replaced or, if repealed and there shall be no replacement therefor, to the same as it is in effect on the date of this Agreement.

100 x A/B

where:

A = the number of votes for the election of directors of the Corporation generally attaching to the Voting Shares Beneficially Owned by such Person; and

B = the number of votes for the election of directors of the Corporation generally attaching to all outstanding Voting Shares.

The percentage of outstanding Voting Shares represented by any particular group of Voting Shares acquired or held by any Person shall be determined in like manner mutatis mutandis.

For purposes of this Agreement a Person is acting jointly or in concert with every Person who is a party to an agreement, commitment, arrangement or understanding, whether formal or informal or written or unwritten, with the first Person to acquire or Offer to Acquire any Voting Shares or Convertible Securities (other than: (a) customary agreements with and between underwriters and/or banking group members and/or selling group members with respect to a distribution of securities by the Corporation; (b) pledges of securities in the ordinary course of business; and (c) Permitted Lock-Up Agreements).

Certificates representing Voting Shares which are issued after the Record Time but prior to the earlier of the Separation Time and the Expiration Time, shall also evidence one Right for each Voting Share represented thereby until the earlier of the Separation Time or the Expiration Time and shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

Until the earlier of the Separation Time or the Expiration Time (as both terms are defined in the Shareholder Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Shareholder Rights Plan Agreement dated as of March 22, 2024, as may be amended, restated or supplemented from time to time (the "Shareholder Rights Agreement"), between DIRTT Environmental Solutions Ltd. (the "Corporation") and Computershare Trust Company of Canada, as Rights Agent, the terms of which are incorporated herein by reference and a copy of which is on file at the principal executive offices of the Corporation. Under certain circumstances set out in the Shareholder Rights Agreement, the Rights may be amended or redeemed, may expire or may become void (if, in certain cases they are "Beneficially Owned" by an "Acquiring Person" as such terms are defined in the Shareholder Rights Agreement, whether currently held by or on behalf of such Person or a subsequent holder) or may be evidenced by separate certificates and no longer evidenced by this certificate. The Corporation will mail or arrange for the mailing of a copy of the Shareholder Rights Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.

Promptly following the Separation Time, the Corporation will prepare or cause to be prepared and the Rights Agent will mail to each holder of record of Voting Shares as of the Separation Time and, in respect of each Convertible Security converted into Voting Shares after the Separation Time and prior to the Expiration Time, promptly after such conversion, the Corporation will prepare or cause to be prepared and the Rights Agent will mail to the holder so converting (other than in either case an Acquiring Person and any Transferee whose rights are or become null and void pursuant to Section 3.1(b) and, in respect of any Rights Beneficially Owned by such Acquiring Person or Transferee which are not held of record by such Acquiring Person or Transferee, the holder of record of such Rights (a "Nominee")), at such holder's address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):

(x) a Rights Certificate appropriately completed, representing the number of Rights held by such holder at the Separation Time or at the time of conversion, as applicable, and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Corporation may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law, rule or regulation or judicial or administrative order made pursuant thereto or with any rule or regulation of any self-regulatory organization, stock exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage; and

(y) a disclosure statement prepared by the Corporation describing the Rights,

provided that a Nominee shall be sent the materials provided for in (x) and (y) only in respect of all Common Shares held of record by it which are not Beneficially Owned by an Acquiring Person. In order for the Corporation to determine whether any Person is holding Common Shares which are Beneficially Owned by another Person, the Corporation may require such first Person to furnish such information and documentation as the Corporation deems necessary.

The Exercise Price, the number and kind of securities subject to purchase upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 2.3 and in Article 3.

then the Exercise Price and the number of Rights outstanding (or, if the payment or effective date therefor shall occur after the Separation Time, the securities purchasable upon exercise of Rights) shall be adjusted as of the payment or effective date in the manner set forth below.

If the Exercise Price and number of Rights outstanding are to be adjusted:

x the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of Common Shares (or other capital stock) (the "Expansion Factor") that a holder of one Common Share immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter as a result thereof; and

y each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor, and the adjusted number of Rights will be deemed to be distributed among the Common Shares with respect to which the original Rights were associated (if they remain outstanding) and the shares issued in respect of such dividend, subdivision, change, consolidation or issuance, so that each such Common Share (or other capital stock) will have exactly one Right associated with it.

For greater certainty, if the securities purchasable upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right after such adjustment will be the securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter as a result of such dividend, subdivision, change, consolidation or issuance.

Adjustments made pursuant to this Section 2.3(a) shall be made successively, whenever an event referred to in this Section 2.3(a) occurs.

If, after the Effective Date and prior to the Expiration Time, the Corporation shall issue any shares of capital stock other than Common Shares in a transaction of a type described in Subsections 2.3(a)(i) or 2.3(a)(iv), shares of such capital stock shall be treated herein as nearly equivalent to Common Shares as may be practicable and appropriate under the circumstances and the Corporation and the Rights Agent agree to amend this Agreement in order to effect such treatment.

If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1, the adjustment provided for in this Section 2.3 shall be in addition to, and shall be made prior to, any adjustment required under Section 3.1.

In the event the Corporation shall at any time after the Effective Date and prior to the Separation Time issue any Common Shares otherwise than in a transaction referred to in this Subsection 2.3(a), each such Common Share so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such associated Common Share.

In case such subscription price may be paid by delivery of consideration, part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights, options or warrants are not so issued, or if issued, are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed, or to the Exercise Price which would be in effect based upon the number of Common Shares (or securities convertible into, or exchangeable or exercisable for Common Shares) actually issued upon the exercise of such rights, options or warrants, as the case may be.

For purposes of this Agreement, the granting of the right to purchase Common Shares (whether from treasury or otherwise) pursuant to any Dividend Reinvestment Plan or any employee benefit, stock option or similar plans shall be deemed not to constitute an issue of rights, options or warrants by the Corporation; provided, however, that, in the case of any Dividend Reinvestment Plan or share purchase plan, the right to purchase Common Shares is at a price per share of not less than 90% of the current market price per share (determined as provided in such plans) of the Common Shares.

hereafter made by the Corporation to holders of its Common Shares, subject to applicable taxation laws, shall not be taxable to such shareholders or shall subject such shareholders to a lesser amount of tax.

Failure to file such certificate or to cause such notice to be given as aforesaid, or any defect therein, shall not affect the validity of any such adjustment or change.

Each Person in whose name any certificate for Common Shares or other securities, if applicable, is issued upon the exercise of Rights shall for all purposes be deemed to have become the absolute holder of record of the Common Shares or other securities, if applicable, represented thereon, and such certificate shall be dated the date upon which the Rights Certificate evidencing such Rights was duly surrendered in accordance with Subsection 2.2(d) (together with a duly completed Election to Exercise) and payment of the Exercise Price for such Rights (and any applicable transfer taxes and other governmental charges payable by the exercising holder hereunder) was made; provided, however, that if the date of such surrender and payment is a date upon which the Common Share transfer books of the Corporation are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the Common Share transfer books of the Corporation are open.

then, in the absence of notice to the Corporation or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Corporation shall execute and upon the Corporation's request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen.

The Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever. As used in this Agreement, unless the context otherwise requires, the term "holder" of any Right shall mean the registered holder of such Right (or, prior to the Separation Time, of the associated Common Share).

All Rights Certificates surrendered upon exercise or for redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Rights Agent, be delivered to the Rights Agent and, in any case, shall be promptly cancelled by the Rights Agent. The Corporation may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Corporation may have acquired in any manner whatsoever, and all Rights Certificates so delivered shall be promptly cancelled by the Rights Agent. No Rights Certificate shall be countersigned in lieu of or in exchange for any Rights Certificates cancelled as provided in this Section 2.9, except as expressly permitted by this Agreement. The Rights Agent shall, subject to applicable laws, destroy all cancelled Rights Certificates and deliver a certificate of destruction to the Corporation.

Every holder of Rights, by accepting the same, consents and agrees with the Corporation and the Rights Agent and with every other holder of Rights:

No holder, as such, of any Rights or Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose whatsoever the holder of any Common Share or any other share or security of the Corporation which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed or deemed or confer upon the holder of any Right or Rights Certificate, as such, any right, title, benefit or privilege of a holder of Common Shares or any other shares or securities of the Corporation or any right to vote at any meeting of shareholders of the Corporation whether for the election of directors or otherwise or upon any matter submitted to holders of Common Shares or any other shares of the Corporation at any meeting thereof, or to give or withhold consent to any action of the Corporation, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of the Corporation except as expressly provided herein, or to receive dividends, distributions or subscription rights, or otherwise, until the Right or Rights evidenced by Rights Certificates shall have been duly exercised in accordance with the terms and provisions hereof.

shall become null and void without any further action, and any holder of such Rights (including any Transferee) shall thereafter have no right to exercise such Rights under any provision of this Agreement and further shall thereafter not have any other rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. The holder of any Rights represented by a Rights Certificate which is submitted to the Rights Agent upon exercise or for registration or transfer or exchange which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not null and void under this Subsection 3.1(b) shall be deemed to be an Acquiring Person for the purposes of this Subsection 3.1 and such Rights shall become null and void.

The Rights represented by this Rights Certificate were issued to a Person who was an Acquiring Person or an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Shareholder Rights Agreement) or a Person who was acting jointly or in concert with an Acquiring Person or an Affiliate or Associate of such Person. This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances specified in Subsection 3.1(b) of the Shareholder Rights Agreement.

provided, however, that the Rights Agent shall not be under any responsibility to ascertain the existence of facts that would require the imposition of such legend but shall impose such legend only if instructed to do so by the Corporation in writing or if a holder fails to certify upon transfer or exchange in the space provided on the Rights Certificate that such holder is not a Person described in such legend and provided further that the fact that such legend does not appear on a certificate is not determinative of whether any Rights represented thereby are void under this Section.

The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, all of which the Corporation and the holders of certificates for Common Shares and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

The Rights Agent may resign and be discharged from its duties under this Agreement upon 60 days' notice (or such lesser notice as is acceptable to the Corporation) in writing mailed to the Corporation and to each transfer agent of Common Shares by registered or certified mail and to the holders of Rights in accordance with Section 5.9. The Corporation may remove the Rights Agent upon 30 days' notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Shares by registered or certified mail and to the holders of Rights in accordance with Section 5.9. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Corporation will appoint a successor to the Rights Agent. If the Corporation fails to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then by prior written notice to the Corporation the resigning Rights Agent or the holder of any Rights (which holder shall, with such notice, submit such holder's Rights Certificate, if any, for inspection by the Corporation), may apply, at the Corporation's expense, to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Corporation or by such a court, shall be a corporation incorporated under the laws of Canada or a province thereof authorized to carry on the business of a trust company in the Province of Alberta. After appointment, the successor Rights Agent will be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall, upon payment in full of any outstanding amounts owing by the Corporation to the Rights Agent under this Agreement, deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Corporation will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares, and mail a notice thereof in writing to the holders of the Rights in accordance with Section 5.9. Failure to give any notice provided for in this Section 4.4, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of any successor Rights Agent, as the case may be.

The Rights Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason, the Rights Agent reasonably determines that such an act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Rights Agent reasonably determine at any time that its acting under this Agreement has resulted in it being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days' prior written notice to the Corporation, provided: (i) that the Rights Agent's written notice shall describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Rights Agent's satisfaction within such 10 day period, then such resignation shall not be effective.

Th e parties acknowledge that federal and/or provincial legislation that addresses the protection of individual's personal information (collectively, "Privacy Laws") applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, neither party will take or direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Corporation will, prior to transferring or causing to be transferred personal information to the Rights Agent, obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or will have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Rights Agent will use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws.

Notwithstanding any other provision of this Agreement, and whether such losses or damages are foreseeable or unforeseeable, the Rights Agent shall not be liable under any circumstances whatsoever for any (a) breach by any other party of securities law or other rule of any securities regulatory authority, (b) lost profits or (c) special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages.

No Person shall have any rights whatsoever pursuant to this Agreement or in respect of any Right after the Expiration Time, except the Rights Agent as specified in Section 4.1 of this Agreement.

Notwithstanding any of the provisions of this Agreement or the Rights to the contrary, the Corporation may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change in the number or kind or class of securities purchasable upon exercise of Rights made in accordance with the provisions of this Agreement.

Any such amendment shall be effective from the date of the resolution of the Board of Directors adopting such amendment, until it is confirmed or rejected or until it ceases to be effective (as described in the next sentence) and, where such amendment is confirmed, it continues in effect in the form so confirmed. If such amendment is rejected by the shareholders or the holders of Rights or is not submitted to the shareholders or holders of Rights as required, then such amendment shall cease to be effective from and after the termination of the meeting (or any adjournment of such meeting) at which it was rejected or to which it should have been but was not submitted or from and after the date of the meeting of holders of Rights that should have been but was not held, and no subsequent resolution of the Board of Directors to amend this Agreement to substantially the same effect shall be effective until confirmed by the shareholders or holders of Rights as the case may be.

Subject to the terms of this Agreement, all rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective holders of the Rights. Any holder of Rights, without the consent of the Rights Agent or of the holder of any other Rights, may, on such holder's own behalf and for such holder's own benefit and the benefit of other holders of Rights enforce, and may institute and maintain any suit, action or proceeding against the Corporation to enforce such holder's right

to exercise such holder's Rights, or Rights to which such holder is entitled, in the manner provided in such holder's Rights Certificate and in this Agreement.

Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.

Any obligation of the Corporation or action or event contemplated by this Agreement shall be subject to the receipt of any requisite approval or consent from any governmental or regulatory authority, including without limiting the generality of the foregoing, any necessary approvals of the Toronto Stock Exchange, or any other applicable stock exchange or market or national securities quotation system.

In case the Corporation shall propose after the Separation Time and prior to the Expiration Time to effect or permit (in cases where the Corporation's permission is required) any Flip-in Event or to effect the liquidation, dissolution or winding up of the Corporation or the sale of all or substantially all of the Corporation's assets, then, in each such case, the Corporation shall give to each holder of a Right, in accordance with Section 5.9 hereof, a notice of such proposed action, which shall specify the date on which such Flip-in Event, liquidation, dissolution, or winding up is to take place, and such notice shall be so given at least 20 Business Days prior to the date of taking of such proposed action by the Corporation.

Without limiting the generality of the foregoing, nothing contained herein shall be construed to suggest or imply that the Board of Directors shall not be entitled to recommend that holders of Voting Shares reject or accept any Take-over Bid or take any other action (including, without limitation, the commencement, prosecution, defence or settlement of any litigation and the submission of additional or alternative Take-over Bids or other proposals to the holders of Voting Shares) with respect to any Take-over Bid or otherwise that the Board of Directors believes is necessary or appropriate in the exercise of its fiduciary duties.

The Corporation agrees that if the Corporation fails to fulfil any of its obligations pursuant to this Agreement, then the Corporation will reimburse the holder of any Rights for the costs and expenses (including legal fees) incurred by such holder, on a solicitor and his own client basis, to enforce his rights pursuant to any Rights or this Agreement.

All the covenants and provisions of this Agreement by or for the benefit of the Corporation or the Rights Agent shall bind and enure to the benefit of their respective successors and assigns hereunder.

Nothing in this Agreement shall be construed to give to any Person other than the Corporation, the Rights Agent and the holders of the Rights any legal or equitable right, remedy or claim under this Agreement; further, this Agreement shall be for the sole and exclusive benefit of the Corporation, the Rights Agent and the holders of the Rights.

This Agreement and each Right issued hereunder shall be deemed to be a contract made under the laws of the Province of Alberta and for all purposes shall be governed by and construed in accordance with the laws of such Province applicable to contracts to be made and performed entirely within such Province.

Les parties aux présentes ont exigé que la présente convention ainsi que tous les documents et avis qui s'y rattachent ou qui en coulent soient redigés en langue anglaise. The parties hereto have required that this Agreement and all documents and notices related thereto or resulting therefrom be drawn up in English.

If any term or provision hereof or the application thereof to any circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective only as to such jurisdiction and to the extent of such invalidity or unenforceability in such jurisdiction without invalidating or rendering unenforceable or ineffective the remaining terms and provisions hereof in such jurisdiction or the application of such term or provision in any other jurisdiction or to circumstances other than those as to which it is specifically held invalid or unenforceable.

This Agreement amends and restates the Original Agreement. Notwithstanding its amendment and restatement as of the date hereof, this Agreement is effective and in full force and effect in accordance with its terms and conditions from and after the Effective Date. If this Agreement is not confirmed by resolution passed by a majority of the votes cast by the Independent Shareholders who vote in respect of such confirmation at a meeting of shareholders to be held not later than six months from the Effective Date, or such other date as may be agreed to by the Toronto Stock Exchange, then this Agreement and all outstanding Rights shall terminate and be void and of no further force and effect on and from the date which is the earlier of (a) the date of termination of the meeting called to consider the confirmation of this Agreement and (b) six months from the Effective Date, or such other date as may be agreed to by the Toronto Stock Exchange.

This Agreement must be reconfirmed by a resolution passed by a majority of the votes cast by Independent Shareholders who vote in respect of such reconfirmation at every third annual meeting of the Corporation following the meeting at which this Agreement is confirmed. If this Agreement is not so reconfirmed or is not presented for reconfirmation at such annual meeting, then this Agreement and all outstanding Rights shall terminate and be void and of no further force and effect on and from the date of termination of the applicable annual meeting; provided that termination shall not occur if a Flip-in Event has occurred (other than a Flip-in Event which has been waived) prior to the date upon which this Agreement would otherwise terminate pursuant to this Section 5.18.

All actions, calculations and determinations (including all omissions with respect to the foregoing) which are done or made or approved by the Board of Directors in connection herewith, in good faith, shall not subject the Board of Directors or any director of the Corporation to any liability to the holders of the Rights.

If in the opinion of the Board of Directors (who may rely upon the advice of counsel) any action or event contemplated by this Agreement would require compliance by the Corporation with the securities laws or comparable legislation of a jurisdiction outside Canada or the United States, the Board of Directors acting in good faith shall take such actions as it may deem appropriate to ensure that such compliance is not required, including without limitation establishing procedures for the issuance to a Canadian resident Fiduciary of Rights or securities issuable on exercise of Rights, the holding thereof in trust for the Persons entitled thereto (but reserving to the Fiduciary or to the Fiduciary and the Corporation, as the Corporation may determine, absolute discretion with respect thereto) and the sale thereof and remittance of the proceeds of such sale, if any, to the Persons entitled thereto. In no event shall the Corporation or the Rights Agent be required to issue or deliver Rights or securities issuable on exercise of Rights to persons who are citizens, residents or nationals of any jurisdiction other than Canada or the United States, in which such issue or delivery would be unlawful without registration of the relevant Persons or securities for such purposes.

Time shall be of the essence in this Agreement.

This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute one and the same instrument.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.

Until adjustment thereof in certain events as provided in the Shareholder Rights Agreement, the Exercise Price shall be:

(a) until the Separation Time, an amount equal to three times the Market Price (as such term is defined in the Shareholder Rights Agreement), from time to time, per Common Share; and

(b) from and after the Separation Time, an amount equal to three times the Market Price, as at the Separation Time, per Common Share.

In certain circumstances described in the Shareholder Rights Agreement, each Right evidenced hereby may entitle the registered holder thereof to purchase or receive assets, debt securities or shares in the capital of the Corporation other than Common Shares, or more or less than one Common Share, all as provided in the Shareholder Rights Agreement.

This Rights Certificate is subject to all of the terms and provisions of the Shareholder Rights Agreement, which terms and provisions are incorporated herein by reference and made a part hereof and to which Shareholder Rights Agreement reference is hereby made for a full description of the rights, limitations of

If this Rights Certificate shall be exercised in part, the registered holder shall be entitled to receive, upon surrender hereof, another Rights Certificate or Rights Certificates for the number of whole Rights not exercised.

Subject to the provisions of the Shareholder Rights Agreement, the Rights evidenced by this Rights Certificate may be, and under certain circumstances are required to be, redeemed by the Corporation at a redemption price of $0.00001 per Right.

No fractional Common Shares will be issued upon the exercise of any Right or Rights evidenced hereby, but in lieu thereof a cash payment will be made, as provided in the Shareholder Rights Agreement.

No holder of this Rights Certificate, as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Common Shares or of any other securities which may at any time be issuable upon the exercise hereof, nor shall anything contained in the Shareholder Rights Agreement or herein be construed to confer upon the holder hereof, as such, any of the Rights of a shareholder of the Corporation or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in the Shareholder Rights Agreement), or to receive dividends or subscription rights, or otherwise, until the Rights evidenced by this Rights Certificate shall have been exercised as provided in the Shareholder Rights Agreement.
