You are cordially invited to attend the 2024 annual and special meeting of shareholders (the “Meeting”) of DIRTT Environmental Solutions Ltd. (“DIRTT”), which will be held virtually at 10:00 a.m. MDT on Thursday, May 9, 2024.

The matters expected to be acted upon at the Meeting are described in the accompanying Notice of Annual Meeting of Shareholders and Proxy Statement. You are entitled to vote at the Meeting and any adjournments or postponements of the Meeting only if you were a shareholder as of the close of business on March 20, 2024.

Your vote is important. Whether or not you can attend the Meeting, please read the Management Information Circular and Proxy Statement carefully, and then cast your vote as soon as possible over the Internet, by telephone, or by completing and returning the proxy card so that your shares will be represented at the Meeting. Returning the proxy means your vote will mean that you are represented at the Meeting regardless of whether or not you attend. Returning the proxy does not deprive you of your right to attend the Meeting and to vote your shares at the Meeting.

Our annual and special meeting of shareholders (the “Meeting”) is scheduled to be held on Thursday, May 9, 2024 at 10:00 a.m. MDT. The Meeting is scheduled to be held in a virtual-only format via live audio webcast online at meetnow.global/MSRJWGU.

Only registered holders of the Company’s Common Shares at the close of business on March 20, 2024, the record date for the Meeting, are entitled to receive notice of and to vote at the Meeting or any adjournment or postponement thereof.

Registered shareholders and duly appointed proxyholders will be able to attend the Meeting, ask questions and vote, provided they are present virtually, connected to the Internet and comply with all of the requirements set out in the Management Information Circular and Proxy Statement. Non-registered (or beneficial) shareholders who have not duly appointed themselves as proxyholder will be able to attend the Meeting and ask questions, but will not be able to vote at the Meeting. A shareholder who wishes to appoint a person other than the management nominees identified on their proxy card or voting instruction form (including a non-registered shareholder who wishes to appoint themselves to attend) must carefully follow the instructions in the Management Information Circular and Proxy Statement and on the proxy card or voting instruction form. These instructions include the additional step of registering such proxyholder with our transfer agent, Computershare Trust Company of Canada, after submitting their proxy card or voting instruction form. Failure to register the proxyholder with our transfer agent will result in the proxyholder not receiving a username to participate in the Meeting and only being able to attend as a guest.

The specific details of the matters proposed to be put before the Meeting are set forth in the Management Information Circular and Proxy Statement of the Company, which accompanies this Notice of Annual Meeting.

Registered holders of Common Shares may vote their proxies by signing, dating and returning a proxy card or by using the Internet or telephone pursuant to the instructions on their proxy card. If your Common Shares are held in the name of a bank or broker, you may be able to vote on the Internet or by telephone. Please follow the instructions on the voting instruction form you receive. Voting by using the Internet or telephone, or by returning your proxy card or voting instruction form in advance of the Meeting, does not preclude you from attending the Meeting online.

Your vote is important. Whether or not you expect to attend the Meeting, please vote over the Internet, by telephone or by completing and promptly returning the enclosed proxy card or voting instruction form so that your shares may be represented at the Meeting.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL AND SPECIAL MEETING SCHEDULED TO BE HELD ON THURSDAY, MAY 9, 2024

The Proxy Statement, Notice of Annual Meeting, the related proxy card and the 2023 Annual Report to Shareholders are available free of charge at www.dirtt.com/investors.

This management information circular and proxy statement (the “Proxy Statement”), dated March 27, 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 annual and 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 Thursday, May 9, 2024 at 10:00 a.m. MDT for the purposes set forth in the Notice of Annual Meeting.

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

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.

The Company uses the notice-and-access process as its method of communication with shareholders for voting and proxy-related materials. Access to this Proxy Statement, Notice of Annual Meeting, the related proxy card and the 2023 Annual Report to Shareholders (collectively, the “Proxy Materials”) will be provided to our shareholders via the Internet, with paper copies free of charge upon request. Accordingly, on or about March 28, 2024, we will begin mailing a Notice of Internet Availability of Proxy Materials (“Notice of Internet Availability”) to shareholders entitled to vote at the Meeting containing instructions on how to access the Proxy Materials and how to vote online. Please follow the instructions on the Notice of Internet Availability for requesting paper or e-mail copies of our Proxy Materials. In addition, shareholders of record may request to receive Proxy Materials in printed form by mail or electronically by e-mail on an ongoing basis for future shareholders meetings. We believe electronic delivery will expedite the receipt of the materials and will help lower the costs of our Proxy Materials. Please note that, while our Proxy Materials are available at the website referenced in the Notice of Internet Availability and on our website, no other information contained on either website is incorporated by reference into or considered to be a part of this document.

We are permitted under applicable securities laws to deliver a single Notice of Internet Availability 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 57 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$” or “CAD$.” Unless otherwise stated, all figures presented in Canadian dollars and translated into U.S. dollars were calculated using the daily average exchange rate as reported by the H.10 statistical release of the Board of Governors of the Federal Reserve System on December 29, 2023 of C$1.3202 = US$1.00.

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 March 20, 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 191,456,899 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 63,818,967 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, each discussed below, 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 May 7, 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:

•

During the Meeting. You may vote your Common Shares during the Meeting by appointing yourself as the proxyholder for your Common Shares before the Meeting in accordance with the voting instruction form provided to you by your intermediary, returning the voting instruction form to your intermediary in accordance with the instructions, and registering yourself as proxyholder with Computershare. You will then receive a separate username that may be used to attend and participate at the Meeting. See also “Appointment of a Proxyholder and Registration for the Meeting” and “Attending and Participating at the Meeting” below.

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. 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 and applicable law, as described under “Shareholder Proposals.”

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 May 7, 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 May 7, 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/MSRJWGU. 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/MSRJWGU. 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.

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 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 or withhold authority to vote for one or more nominees for director or the appointment of the auditor of the Company 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, Proposals No. 1 and No. 3 are not considered “routine” proposals, and therefore, U.S. brokers cannot exercise discretionary authority regarding such proposals for non-registered owners who have not returned voting instructions. Proposal No. 2 is considered a “routine” proposal, and therefore, U.S. brokers can exercise discretionary authority regarding this proposal for non-registered owners who have not returned voting instructions.

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

Proposal No. 1 — Election of directors. The election of each director nominee must be approved by a plurality of votes cast, which means a director will be elected in an uncontested election if he or she receives at least one vote cast “FOR” such nominee. You may either vote “FOR” or “WITHHOLD” your vote with respect to the election of each director nominee. If you vote “FOR” the election of a nominee, your vote will be cast accordingly. If you select “WITHHOLD” with respect to the election of a nominee, your vote will not be counted as a vote cast for the purposes of electing such nominee but will be considered in the application of the Company’s majority voting policy (the “Majority Voting Policy”). See “Proposal No. 1 – Election of Directors – Majority Voting Policy” on page 7 of this Proxy Statement. Pursuant to our Majority Voting Policy, a “WITHHOLD” vote is treated as a share present or represented and entitled to vote on the director nominee and has the same effect as a vote “against” the nominee. The total votes cast with respect to this proposal under our plurality voting requirement and our Majority Voting Policy will exclude abstentions, broker non-votes, and failures to vote with respect to that director’s election. Shareholders do not have the right to cumulative voting in the election of directors.

Proposal No. 2 — Appointment of the independent registered public accounting firm at remuneration to be set by the Board. The proposal to appoint PwC as our independent registered public accounting firm must be approved by a plurality of votes cast, which means the proposal may be approved by any one or more shareholders voting “FOR” such proposal. For purposes of this proposal, votes cast at the Meeting include only those votes cast “FOR” the appointment of the proposed independent registered public accounting firm. You may either vote “FOR” or “WITHHOLD” your vote with respect to the appointment of the proposed independent registered public accounting firm. If you vote “FOR” the appointment of the proposed independent registered public accounting firm, your vote will be cast accordingly. If you select “WITHHOLD,” your vote will not be counted as a vote cast for purposes of appointing the proposed independent registered public accounting firm.

Proposal No. 3 — Approval of the A&R LTIP Resolution. The proposal to approve the adoption of the A&R LTIP to increase the aggregate number of Common Shares issuable thereunder, must be approved by the affirmative vote of a simple majority (50% plus one) of the Common Shares present, either in person or by proxy, and entitled to vote (meaning that at least a simple majority of the votes cast 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.

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 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 our 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 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.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012. For as long as we are an emerging growth company, we will not be required to include a Compensation Discussion and Analysis section in this Proxy Statement and have elected to comply with the scaled-down executive compensation disclosure requirements applicable to emerging growth companies.

The audited consolidated financial statements of the Company for the year ended December 31, 2023 and the independent registered public accounting report thereon will be placed before the Meeting, or any adjournment or postponement thereof. No vote by the shareholders with respect to the audited consolidated financial statements is required. The audited consolidated financial statements were audited by PwC and approved by the Audit Committee of the Board. Copies of these materials may be obtained by shareholders upon request. These materials are also available on our website at www.dirtt.com, SEDAR+ at www.sedarplus.ca, and on the Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”) at www.sec.gov.

At the Meeting, our shareholders will be asked to elect each of the eight director nominees identified below, each to serve until the close of our next annual meeting of shareholders or until his or her successor has been duly elected or appointed. All director nominees proposed for election as directors are currently directors of the Company. All director nominees were recommended to the Board by the Corporate Governance and Compensation Committee.

The present composition of our Board comprises eight members. Pursuant to the Company’s by-laws, the Board has resolved to establish the number of directors constituting the Board at eight, with immediate effect following the conclusion of the Meeting. Consequently, it is imperative to observe that voting, whether conducted by proxy or at the Meeting, must adhere strictly to the nominees proposed for election as directors, and may not exceed the specified number.

Additionally, see “Proposal No. 1 – Election of Directors – Majority Voting Policy” on page 7 for information about the Company’s Majority Voting Policy.

There are no family relationships among any of our executive officers, directors or director nominees.

As set forth in the enclosed proxy card, shareholders may vote “FOR” or “WITHHOLD” their vote for each director nominee. In accordance with the Board’s Majority Voting Policy, if any director nominee receives a number of votes “WITHHELD” from his or her election that is equal to or greater than votes “FOR” such election, such nominee will submit his or her offer of resignation to the lead director or Chair of the Board. The Corporate Governance and Compensation Committee will review such resignation offer and make a recommendation to the Board of whether or not to accept such resignation. The Corporate Governance and Compensation Committee is expected to recommend acceptance of the resignation offer to the Board, and the Board is expected to accept such recommendation and resignation offer, except in situations where exceptional circumstances would warrant the director nominee continuing to serve on the Board. The director nominee will not participate in any deliberations of the Corporate Governance and Compensation Committee or the Board with respect to his or her resignation offer. Within 90 days of receiving the resignation offer, the Board will make a decision and the Company will issue a press release announcing whether they have accepted or rejected the director nominee’s resignation, a copy of which will be provided to the TSX. The resignation will be effective when accepted by the Board. The Majority Voting Policy does not apply to contested elections in which the number of director nominees for election is greater than the number of director positions on the Board.

None of the Company’s proposed directors are, at the date of this Proxy Statement, or have been, within 10 years prior to the date of this Proxy Statement, a director, chief executive officer or chief financial officer of a company that: (a) while such person was acting in that capacity was the subject of a cease trade or similar order or an order that denied the relevant company access to any exemption under securities legislation for a period of more than 30 consecutive days (an “order”); or (b) was subject to an order that was issued

after that person ceased to be a director, chief executive officer or chief financial officer of the relevant company and which resulted from an event that occurred while that person was acting in the capacity as director, chief executive officer or chief financial officer.

Except as set out below, none of the Company’s proposed directors have been subject to: (a) any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority, or has entered into a settlement agreement with a securities regulatory authority; or (b) any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable securityholder in deciding whether to vote for a proposed director.

Other than as described below, none of the Company’s proposed directors: (a) are at the date of this Proxy Statement, or have been, within 10 years prior to the date of this Proxy Statement, a director or executive officer of any company that, while that person was acting in that capacity, or within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold its assets, (b) has, within 10 years prior to the date of this Proxy Statement, become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold the assets of the director or executive officer, as applicable, or (c) has been involved in any legal proceedings requiring disclosure under U.S. federal securities laws.

Mr. Shaun Noll (at the relevant time DBA as Stirling Capital Management) self-reported a violation of s. 25230 of the California Corporate Securities Law of 1968 (engaging in unlicensed investment advisor activity), arising as a result of the inadvertent non-payment of annual license dues. In or around March 2014, Mr. Noll entered into a Settlement Agreement with the Commissioner of Business Oversight of the State of California, under which Mr. Noll agreed to take steps to comply with applicable laws relating to licensing as an investment advisor and to pay a nominal penalty of $6,500. The penalty has been fully paid and there are no sanctions on Mr. Noll.

PROPOSAL NO. 2 – APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of our Board has recommended that PwC be appointed as our independent registered public accounting firm for the fiscal year ending December 31, 2024, and that the remuneration of PwC for such year be fixed by our directors.

At the Meeting, or any adjournment or postponement thereof, shareholders will be asked to appoint PwC to serve as our independent registered public accounting firm until the next annual meeting of shareholders at a remuneration to be fixed by the Board. PwC was first appointed as our independent registered public accounting firm effective June 9, 2017.

The Audit Committee reviews and pre-approves all audit and non-audit services performed by our independent registered public accounting firm. The Audit Committee approved all services rendered by PwC in the fiscal year ended December 31, 2023, in accordance with these policies.

In its review of non-audit services, the Audit Committee considers, among other things, the possible impact of the performance of such services on the independence of our independent registered public accounting firm. The Audit Committee has determined that the non-audit services performed by PwC in the fiscal year ended December 31, 2023, were compatible with maintaining the independence of our independent registered public accounting firm. Additional information concerning the Audit Committee and its activities can be found in this Proxy Statement under “Corporate Governance.”

Representatives of PwC are expected to be present at the Meeting, will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate shareholder questions.

The following table sets out the fees for services provided to us by our independent registered public accounting firm for the years ended December 31, 2023 and 2022.

PROPOSAL NO. 3 – APPROVAL OF THE COMPANY'S SECOND AMENDED AND RESTATED LONG TERM INCENTIVE PLAN

The Board unanimously approved, subject to receiving approval of the TSX and the shareholders, the A&R LTIP, which increases the aggregate number of Common Shares reserved and available for issuance since the inception of the plan on May 22, 2020 by 15,000,000 such that the total Common Shares reserved under the A&R LTIP would increase from the 12,350,000 currently reserved under the LTIP (defined below) to 27,350,000 plus the number of Common Shares subject to stock options granted under the Option Plan (as defined below) that, following May 22, 2020, expire or for any reason are canceled or terminated without having been exercised in full. Other than the increase to the maximum number of Common Shares reserved and available for issuance thereunder, the terms of the A&R LTIP will be the same as those of the LTIP. At the Meeting, our shareholders will be asked to consider and, if deemed advisable, pass the A&R LTIP Resolution, the full text of which is set out below. If approved by the shareholders and the TSX, the adoption of the A&R LTIP to increase the aggregate number of Common Shares issuable thereunder will become effective on May 9, 2024. The TSX has conditionally approved the adoption of the A&R LTIP, subject to receipt of shareholder approval at the Meeting. The Board unanimously recommends that our shareholders vote to approve the A&R LTIP Resolution.

On April 3, 2023, the Board approved the DIRTT Environmental Solutions Ltd. Amended and Restated Long Term Incentive Plan (the “LTIP”), which amended and restated the DIRTT Environmental Solutions Ltd. Long-Term Incentive Plan, originally adopted on May 22, 2020 (the “Original LTIP”). The LTIP replaced the Company’s Deferred Share Unit Plan for Non-Employee Directors (as amended and restated, the “DSU Plan”), the Performance Share Unit Plan (the “PSU Plan”) and the Amended and Restated Stock Option Plan (the “Option Plan” and, together with the DSU Plan and the PSU Plan, the “Prior Plans”), subject to shareholder approval, which was obtained on May 30, 2023. Any awards that remain outstanding under the Prior Plans are governed by the terms of the applicable Prior Plan and the terms of the award agreement pursuant to which such award was granted, as applicable.

The ability to grant share-based compensation is critical for meeting the Company’s compensation objectives and for enabling the Company to attract and retain highly-qualified employees, consultants and directors. The proposed adoption of the A&R LTIP to increase the number of Common Shares reserved and available for issuance under the LTIP, if approved, will allow us to continue to provide share-based compensation to our employees, consultants and directors, which is a vital element of our compensation program.

For additional information regarding share-based awards previously granted, please see Note 16 to our consolidated financial statements on Form 10-K for the year ended December 31, 2023 and the table included in this Proposal No. 3 below, entitled “Securities Authorized for Issuance Under Equity Compensation Plans.” As of March 20, 2024, there were 191,456,899 of our Common Shares outstanding. The closing price per Common Share on the TSX as of March 20, 2024 was CAD $0.75.

If our shareholders approve this proposal, we intend to file, pursuant to the Securities Act of 1933, as amended, a registration statement on Form S-8 to register the additional Common Shares available for issuance under the A&R LTIP.

The following summary of the A&R LTIP does not purport to be a complete description of all provisions of the A&R LTIP and should be read in conjunction with, and is qualified in its entirety by reference to, the complete text of the A&R LTIP, which is attached as Appendix A to this proxy statement . The A&R LTIP gives the Compensation Committee the ability to award options (“Options”) (either in the form of incentive stock options (“ISOs”) intended to qualify as such under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”) or Options that are not intended to constitute ISOs (“Nonstatutory Options”)), share appreciation rights (“SARs”), restricted share units (“Restricted Share Units” or “RSUs”), restricted shares (“Restricted Shares”), dividend-equivalent rights (“Dividend-Equivalent Rights”) in conjunction with the grant of Restricted Share Units and deferred share units ("DSUs"), vested share awards (“Share Awards”), other share-based awards (“Other Share-Based Awards”), cash awards (“Cash Awards”), and DSUs (collectively, “Awards”). Unless earlier terminated by action of the Board, the A&R LTIP will terminate on May 30, 2033.

Employees, officers, directors and consultants of the Company and its affiliates are eligible to receive awards under the A&R LTIP. Eligible individuals to whom an Award is granted under the A&R LTIP are referred to as “Participants.” As of March 20, 2024, it is expected that the Company and its affiliates will have approximately 81 employees, 3 officers, 8 non-employee directors, and 1 consultant who will be eligible to participate in the A&R LTIP. A consultant who is a Canadian resident may be required to provide services to the Company for a period of at least 12 months to be eligible to receive an Award. Only directors who are not, apart from their position as a director, an employee of Company or any of its affiliates (“Eligible Directors”) may receive DSU awards.

If the A&R LTIP Resolution is approved, subject to adjustment as described below, the aggregate number of our Common Shares reserved and available for issuance pursuant to the settlement, exercise or redemption of Awards under the A&R LTIP since the inception of the Original LTIP on May 22, 2020 will be (i) 27,350,000, representing approximately 14.3% of the Company’s outstanding Common Shares on a non-diluted basis (9.4% on a fully diluted basis) as of the Record Date (12,350,000 under the LTIP and 15,000,000 approved under the A&R LTIP Resolution), plus (ii) the number of our Common Shares subject to stock options granted under the Option Plan prior to the adoption of the Original LTIP on May 22, 2020 that, following May 22, 2020, expire or for any reason are canceled or terminated without having been exercised in full. For the avoidance of doubt, Common Shares withheld in payment of any exercise or purchase price or taxes related to a stock option granted under the Option Plan will not become available for Awards under the A&R LTIP. The total number of Common Shares that will be available for issuance upon the exercise of ISOs since the inception of the Original LTIP on May 22, 2020 shall be 27,350,000. The A&R LTIP Resolution increases the 12,350,000 current share reserve under the LTIP by 15,000,000 Common Shares for a total of 27,250,000 Common Shares under the A&R LTIP. For the avoidance of doubt, Common Shares issued under the A&R LTIP since the inception of the Original LTIP on May 22, 2020 will count against the total share reserve thereunder. The proposed 15,000,000 increase in Common Shares represents approximately 7.8% of the Company’s outstanding Common Shares on a non-diluted basis (5.1% on a fully diluted basis) as of the Record Date. The share recycling and counting provisions, including clause (ii) in this paragraph, are unchanged by the proposed amendment and restatement.

As of the Record Date, 5,415,078 stock options previously granted under the Option Plan and outstanding on May 22, 2020 expired or were canceled or terminated without having been exercised in full, resulting in 5,415,078 additional Common Shares, representing approximately 2.8% of the Company’s outstanding Common Shares on a non-diluted basis (1.9% on a fully diluted basis), being reserved and available for issuance of Awards pursuant to clause (ii) in the preceding paragraph. As of the Record Date, a total of 208,409 stock options, representing 0.1% of the Company’s outstanding Common Shares on a non-diluted basis (0.1% on a fully diluted basis), remain outstanding under the Option Plan. Thus, if all stock options outstanding as of the Record Date were to expire or be canceled or terminated without having been exercised, a maximum of 208,409 additional Common Shares could become available for new Awards under the A&R LTIP in the future. Accordingly, the maximum number of Common Shares that could become issuable under the A&R LTIP since the inception of the plan in 2020, if the A&R LTIP Resolution is approved, would be 32,973,487 (being the share reserve of 12,350,000 under the current LTIP, plus the increase in share reserve of 15,000,000 if the A&R LTIP is approved, plus the 5,415,078 Common Shares reserved and made available for issuance pursuant to clause (ii) in the preceding paragraph prior to the Record Date, plus the 208,409 Common Shares that could become available for issuance on the expiry, termination or cancellation of outstanding stock options, as described above). The maximum number of Common Shares that could become issuable under the current LTIP since the inception of the plan in 2020 if the A&R LTIP Resolution is not approved would be 17,973,487.

As of the Record Date, a total of 7,729,259 Common Shares have been issued in settlement of Awards granted under the LTIP. A total of 3,513,040 Common Shares are subject to outstanding time-based RSUs and 3,506,655 Common Shares are subject to outstanding performance-based RSUs (“PSUs”) (assuming vesting at 190% of the target amount granted), collectively representing approximately 3.7% of the Company’s outstanding Common Shares on a non-diluted basis (2.4% on a fully diluted basis), and 1,795,974 DSUs to be settled in Common Shares representing approximately 0.9% of the Company’s outstanding Common Shares on a non-diluted basis (0.6% on a fully diluted basis). No other equity awards are outstanding under the LTIP as of such date. Thus, as of the Record Date there were 1,011,741 Common Shares available for issuance under the LTIP that were not subject to outstanding Awards, representing approximately 0.5% of the Company’s outstanding Common Shares on a non-diluted basis (0.3% on a fully diluted basis).

If an Award granted under the A&R LTIP is cancelled, forfeited, exchanged, settled in cash or otherwise terminated without the actual delivery of our Common Shares, any shares subject to such Award will again be available for new Awards under the A&R LTIP. Any Common Shares withheld or surrendered in payment of any taxes relating to Awards will not again be available for new Awards under the A&R LTIP unless such Award is an Option or SAR, in which case such withheld or surrendered Common Shares will again be available for new Awards under the A&R LTIP. In addition, any Common Shares withheld or surrendered in payment of any exercise or purchase price of Options or SARs will again be available for new Awards under the A&R LTIP.

Subject to stock exchange requirements, including stock exchange approval, as applicable, certain Awards granted in substitution or exchange for awards previously granted by a company acquired by the Company or any subsidiary or with which the Company or any subsidiary combines will not reduce the Common Shares authorized for issuance under the A&R LTIP, nor shall shares subject to such Awards be added to the Common Shares available for issuance under the A&R LTIP if such Awards are later cancelled, forfeited or otherwise terminated.

Our Common Shares issued under the A&R LTIP may come from authorized but unissued shares, or (except in the case of Options granted to Canadian taxpayers) from our previously issued Common Shares reacquired by the Company, including shares purchased on the open market.

The maximum number of our Common Shares underlying or relating to Awards which may be granted to any one Participant under the A&R LTIP in any calendar year will not exceed 10% of our total issued and outstanding Common Shares. Furthermore, under the A&R LTIP and all of the Company’s other security-based compensation arrangements, the maximum number of our Common Shares issuable to insiders pursuant to outstanding Awards at any time will not exceed 10% of our total issued and outstanding Common Shares. Under the A&R LTIP and all of the Company’s other security-based compensation arrangements, in any one year period, the maximum number of our Common Shares issued to insiders will not exceed 10% of our total issued and outstanding Common Shares.

The aggregate number of our Common Shares issuable pursuant to outstanding Awards under the A&R LTIP to non-employee directors of the Company will be limited to 1% of our total issued and outstanding Common Shares provided that the value of all Options issuable in any one year period under the A&R LTIP to any one non-employee director of the Company will not exceed CAD $100,000, and the value of all Awards issuable in any one year period under the A&R LTIP to any one non-employee director will not exceed CAD $150,000, in each case, not including any Awards issued or taken in lieu of cash fees or a one-time initial grant to a new director upon joining the Board.

The Compensation Committee shall not grant Awards with a vesting schedule that provides for full or partial vesting less than one year after the date of grant; provided, however, that (i) the Committee may grant Awards with a vesting schedule that provides for full or partial vesting less than one year after the date of grant so long as such Awards do not constitute more than 5% of the number of our Common Shares available for issuance under the A&R LTIP, (ii) Awards may vest upon death, termination of employment or a Change of Control, and (iii) this limitation will not apply to DSUs or to certain Awards granted in substitution or exchange for awards previously granted by a company acquired by the Company or any subsidiary or with which the Company or any subsidiary combines.

The Compensation Committee will administer the A&R LTIP (the “Administrator”). Subject to the terms of the A&R LTIP and applicable law, the Administrator has broad authority to select Participants to receive Awards, determine the types and amounts of Awards and terms and conditions of Awards, modify, waive, or adjust any term or condition of an Award that has been granted, which may include the acceleration of vesting, and interpret and administer the A&R LTIP. Subject to applicable law, the Administrator is also authorized to interpret the A&R LTIP, to establish, amend and rescind any rules and regulations relating to the A&R LTIP, to delegate duties under the A&R LTIP to one or more officers or managers of the Company or its affiliate, and to make any other determinations that it deems necessary or desirable for the administration of the A&R LTIP. The Administrator may correct any defect, supply any omission or reconcile any inconsistency in the A&R LTIP in the manner and to the extent the Administrator deems necessary or desirable.

An Option represents a right to purchase our Common Shares at a fixed exercise price. The Company may grant Options to eligible persons including: (i) ISOs which comply with the requirements of Section 422 of the Code; and (ii) Non-statutory Options. Except in limited circumstances, the exercise price for an Option must not be less than the fair market value per Common Share as of the date of grant (or at least 110% of the fair market value for certain ISOs), nor may the Option be repriced without the prior approval of our shareholders. Options may be exercised as the Administrator determines, but not later than ten years from the date of grant (or five years from the date of grant for certain ISOs). Consistent with the applicable terms of the A&R LTIP, the Administrator determines the methods and form in which payment of the exercise price of an Option may be made and the methods and forms in which our Common Shares will be delivered to a Participant, provided that all Options granted to “Canadian Participants” (as defined in the A&R LTIP) will generally be exercisable only for authorized and unissued Common Shares from treasury. The Administrator may decide to accept any of the following forms of payment for the exercise price: cash or cash equivalents, Common Shares (including previously owned Common Shares or through a cashless exercise, i.e., “net settlement”, a broker-assisted exercise, or other reduction of the amount of Common Shares otherwise issuable pursuant to the Option), other Awards or awards granted under other plans of the Company or any affiliate, other property, or any other legal consideration the Administrator deems appropriate. In the case of an exercise whereby the exercise price is paid with Common Shares, such Common Shares shall be valued based on the Common Shares’ fair market value (as defined in the A&R LTIP) as of the date of exercise.

A SAR is the right to receive an amount equal to the excess of the fair market value of one Common Share on the date of exercise over the grant price of the SAR, payable in either cash or our Common Shares or any combination thereof as determined by the

“Employer” (as defined in the A&R LTIP). Except in limited circumstances, the grant price for a SAR must not be less than the fair market value of a Common Share on the date of grant. No SAR may have a term of more than ten years and any SAR granted to a Canadian Participant will have a term extending not later than December 15th of the calendar year in which such SAR becomes vested and exercisable. A SAR granted in connection with an Option will entitle a Participant, upon exercise, to surrender that Option or any portion thereof, to the extent unexercised, and to receive payment of an amount determined by multiplying (i) the difference obtained by subtracting the exercise price with respect to a Common Share specified in the related Option from the fair market value of a Common Share on the date of exercise of the SAR, by (ii) the number of Common Shares as to which that SAR has been exercised. The Option will then cease to be exercisable to the extent surrendered. SARs granted in connection with an Option will be subject to the terms and conditions of the award agreement governing the Option, which will provide that the SAR is exercisable only at such time or times and only to the extent that the related Option is exercisable and will not be transferable except to the extent that the related Option is transferrable.

A Restricted Share Unit represents a future conditional right to receive a cash payment equal to the fair market value of a Common Share on a specified date as determined by the Administrator, or, at the Company’s discretion, its equivalent in Common Shares (or a combination of cash and Common Shares), provided that, for Canadian Participants, such specified date is on or before that date which is three years following the end of the relevant year of service of the Participant in respect of which the Restricted Share Unit was granted. Restricted Share Units granted to U.S. taxpayers will be settled no later than 70 days following vesting unless otherwise specified in the applicable award agreement. Unless otherwise provided in the applicable award agreement, Dividend-Equivalent Rights will accrue, in the form of additional Restricted Share Units, with respect to each Restricted Share Unit if any cash dividends are paid following grant and before settlement. Such additional Dividend-Equivalent Rights accrued in the form of Restricted Share Units will be subject to the same terms and conditions as the underlying Restricted Share Units.

An award of Restricted Shares is a grant of our Common Shares subject to a risk of forfeiture, restrictions on transferability and any other conditions or restrictions imposed by the Administrator in its discretion. Except as otherwise provided under the terms of an award agreement, the holder of Restricted Shares will generally have rights as a shareholder, including the right to receive dividends on our Common Shares subject to the award of Restricted Shares during the restriction period and, subject to approval of the stock exchange, the right to vote our Common Shares subject to the award of Restricted Shares. Our Common Shares distributed in connection with a share split or share dividend and other property (including cash) distributed as a dividend will be subject to restrictions and a risk of forfeiture to the same extent as the Restricted Shares with respect to which such Common Shares or other property has been distributed. As a condition to the grant of an Award of Restricted Shares, the Administrator may allow a Participant to elect, or may require, that any cash dividends paid on a Restricted Share be automatically reinvested in additional Restricted Shares, applied to the purchase of additional Awards or deferred without interest to the date of vesting of the associated Award of Restricted Shares.

The Administrator may grant vested Common Shares as a Share Award to a Participant as a bonus, as additional compensation, or in lieu of cash compensation any such Participant is entitled to receive, in such amounts and subject to such other terms as the Administrator determines is appropriate.

The Administrator is authorized to grant to Participants Other Share-Based Awards that may be denominated in or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, our Common Shares on such terms and conditions as the Administrator deems appropriate. In addition, the Administrator is authorized to grant Cash Awards on a free-standing basis, as an element of, or a supplement to, or in lieu of any other Award under the A&R LTIP on such terms and conditions as the Administrator deems appropriate.

DSUs may be granted only to Eligible Directors. A DSU represents a future right to receive a cash payment equal to the fair market value of a Common Share on (or within ten days following) the redemption date, or, at the Company’s discretion, its equivalent in Common Shares (or a combination of cash and Common Shares).

Unless otherwise determined prior to the commencement of a particular year by the Board, Eligible Directors will be credited on a quarterly basis for 100% of their annual retainer for the year in the form of DSUs. If the Board determines to satisfy less than 100% of the directors’ annual retainer in DSUs, the director may elect, irrevocably and in advance, to receive up to 100% of their annual

retainer (and other amounts such as committee fees which are not included in the annual retainer) in the form of DSUs. The number of DSUs granted quarterly is determined by dividing the value of the applicable retainer for that quarter by the fair market value of a Common Share on the grant date. DSUs granted in lieu of retainers or fees are fully vested at grant. The Board may, in its discretion, award additional DSUs (not in lieu of a retainer or fee) to non-employee directors on such terms and conditions as it determines, including as to vesting.

Unless otherwise provided in the applicable award agreement, Dividend-Equivalent Rights will accrue, in the form of additional DSUs, with respect to each DSU if any cash dividends are paid following grant and before settlement. Such additional Dividend-Equivalent Rights accrued in the form of DSUs will be subject to the same terms and conditions as the underlying DSUs.

Upon a non-employee director ceasing to be a director of the Company, or any of its affiliates, as a result of death, retirement or otherwise, all DSUs held by such non-employee director shall be settled within ten days of the director’s redemption date, which is defined as (i) the date elected by the non-employee director but in no event earlier than the date the director ceases to be a director of the Company or any of its affiliates and no later than December 15 of the year following the year in which a non-employee director ceases to be a director or (ii) in the case of non-employee directors subject to the United States Internal Revenue Code of 1986, the 30th day from their “Separation from Service,” as defined in the A&R LTIP. If the Company elects to settle a DSU in cash, the non-employee director shall receive a cash payment equal to the number of DSUs multiplied by the fair market value of a Common Share on the redemption date.

Any dividend, or Dividend-Equivalent Right, credited with respect to any Award other than a Share Award (which is an Award of fully vested Common Shares) will be subject to the same time and/or performance based vesting conditions (if any) applicable to such Award and will, if vested, be delivered or paid at the same time as such Award.

Under the A&R LTIP, the fair market value of a Common Share, Restricted Share or Restricted Share Unit, including for purposes of establishing the exercise price of an Option and the grant price of a SAR, will be equal to the closing sale price of our Common Shares, as reported by the principal stock exchange (as described below) on the day immediately preceding the specified date (or if no sales occur on such date, on the last preceding date on which such sales of Common Shares are so reported). If the Common Shares did not trade, then the fair market value will be determined by the Administrator, acting reasonably, using any other appropriate method selected by the Administrator and compliant with applicable laws. If our Common Shares are traded on more than one stock exchange, the fair market value will be determined by looking at the closing price of the principal stock exchange upon which has occurred the greatest trading volume of the Common Shares for the six months (or, to the extent the Common Shares have not been listed, admitted to trading, posted for trading, or quoted upon for at least six months, the next longest period since the Common Shares were initially listed, admitted to trading, posted for trading, or quoted upon) prior to the date of reference; provided, however, that to the extent deemed necessary or appropriate, the Administrator may identify which stock exchange’s price to utilize so long as such determination is made in accordance with applicable law.

The Company and any of its affiliates have the right to deduct or withhold from any Award granted, any payment due or transfer made under any Award or under the A&R LTIP, or from any compensation or other amount owing to a Participant, or require payment or reimbursement from a Participant in respect of, such amounts as may be necessary so as to ensure the Company and its affiliates comply with any applicable law relating to the withholding of tax or other required deductions. The Administrator will determine, in its sole discretion, the form of payment acceptable for such tax withholding obligations, including the delivery of cash or cash equivalents, our Common Shares (including through delivery of previously owned Common Shares, other than, in the case of a Canadian Participant, Common Shares previously issued upon the exercise of an Option within the preceding 24-month period), net settlement, a broker-assisted sale or other cashless withholding or reduction of the amount of Common Shares otherwise issuable or delivered pursuant to the Award, other property or any other legal consideration the Administrator deems appropriate.

In the event of certain equity restructuring events, the Administrator will equitably adjust (i) the aggregate number or kind of shares that thereafter may be delivered under the A&R LTIP, (ii) the number or kind of shares or other property (including cash) subject to an Award, (iii) the terms and conditions of Awards, including the purchase price or exercise price of Awards and performance criteria, as applicable, and (iv) the applicable share-based limitations with respect to Awards provided in the A&R LTIP, in each case to equitably reflect such equity restructuring event.

In the event that the Administrator determines that any dividend or other distribution, recapitalization, share split, share dividend, reverse share split, reorganization, merger, consolidation split-up, spin-off, combination, repurchase, exchange of our Common Shares or other securities of the Company, issuance of warrants or other rights to purchase our Common Shares or other securities of the Company or other similar corporate transactions or events that affects our Common Shares, such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the A&R LTIP and any Awards granted under the A&R LTIP, then the Administrator may equitably adjust any or all of: (i) the number and kind of our Common Shares or other securities which thereafter may be made the subject of Awards; (ii) the number and kind of our Common Shares or other securities subject to outstanding Awards; (iii) the fair market value or the grant or exercise price with respect to any Award or make provision for a cash payment to the holder of an outstanding Award; and (iv) the share-based limitations with respect to Awards issuable to insiders and directors provided in the A&R LTIP; provided, however, that the number of Common Shares subject to any Award denominated in Common Shares will always be a whole number.

Except as provided in the section immediately below, the vesting provisions of the Awards, including treatment upon a termination of employment, will be specified in each Participant’s applicable award agreement and are not specified under the A&R LTIP.

In the event of a Change of Control (as defined in the A&R LTIP), any successor entity will assume any outstanding Awards or will substitute similar Awards for the outstanding Awards, on the same terms and conditions as the original Awards. Unless otherwise provided in the applicable award agreement, if, upon a Change of Control, the successor entity does not comply with such provision of the A&R LTIP, the vesting of all then outstanding Awards will be accelerated in full with effect immediately prior to the Change of Control (vesting for performance-based Awards will be calculated based on target performance through the date of the transaction), and (i) a Participant will be permitted to conditionally exercise any or all of the Participant’s outstanding Options and SARs effective immediately prior to the completion of such transaction, (ii) the settlement date for all outstanding Restricted Share Units shall be deemed to be the date immediately prior to the occurrence of the Change of Control, and (iii) all Restricted Shares shall become fully transferable Common Shares effective immediately prior to the completion of any such transaction constituting the Change of Control, in each case, for the sole purpose of participating in such transaction as a shareholder. Unless otherwise provided in the applicable award agreement, if, within 12 months following the Change of Control, a Participant’s service, consulting relationship or employment is terminated by the Company, its affiliates or the successor entity without “Cause” or the Participant resigns from his or her employment with the Company, its affiliates or the successor entity for “Good Reason” (each quoted term as defined in the A&R LTIP), then the vesting and exercisability of all Awards held by such Participant will be accelerated in full and the expiration date of any Options and SARs held by such Participant will be the 60th day following such Participant’s termination date.

Awards may be granted under the A&R LTIP in substitution for awards held by individuals who become Participants as a result of a merger, consolidation or acquisition of another entity or the assets of another entity by or with us or an affiliate. Such substituted Awards referred to in the immediately preceding sentence that are Options or SARs may have an exercise price or grant price that is less than the fair market value of one of our Common Shares on the date of the substitution if such substitution complies with applicable laws and stock exchange rules.

The Board may amend, alter, suspend, discontinue or terminate the A&R LTIP or any Award without the consent of any shareholder, Participant, other holder or beneficiary of an Award or other person; provided, however, that, subject to the Company’s rights to adjust Awards in connection with certain recapitalizations, restructurings and related transactions as described above, no such amendment, alteration, suspension, discontinuation or termination that would impair the rights of a Participant or holder or beneficiary under any Award previously granted, will not to that extent be effective without the consent of the Participant or holder or beneficiary of an Award. Further, without the approval of shareholders, no amendment, alteration, suspension, discontinuation or termination will be made that would: (i) increase the total number of our Common Shares available for Awards under the A&R LTIP, (ii) amend any outstanding Option or SAR to reduce its exercise price, extend its term beyond the original term set forth in the applicable award agreement or take any other action that would be considered a repricing under the applicable stock exchange listing standards, (iii) remove or exceed the insider participation limits, (iv) increase the non-employee director compensation limits, (v) have the effect of amending the section of the A&R LTIP that enumerates what actions require approval of shareholders, (vi) modify or amend the provisions of the A&R LTIP in any manner that would permit Awards to be transferable or assignable in a manner other than as currently provided in the A&R LTIP, (vii) change eligible Participants under the A&R LTIP, which would have the effect of

broadening or increasing insider participation, or (viii) otherwise cause the A&R LTIP to cease to comply with any tax or regulatory requirement. Without limiting the generality of the preceding sentence, shareholder approval will not be required for any of the following types of amendments: (a) amendments for the purpose of curing any ambiguity, error, or omission in the A&R LTIP or Award or to correct or supplement any provision of the A&R LTIP or Award that is inconsistent with any other provision of the A&R LTIP or Award; (b) amendments necessary to comply with applicable laws; (c) amendments of a “housekeeping” nature; (d) amendments intended to comply with changes in tax or regulatory requirements; or (e) a change to the termination provisions of Awards which does not entail an extension beyond the original expiry date of such Award.

Participants may not assign, alienate, pledge, attach, sell or otherwise transfer or encumber any Award, other than a Share Award, except by will or the laws of descent or by the designation of a beneficiary. Each Award, and each right under any Award, will only be exercised by a Participant during that Participant’s lifetime (or, if permissible under applicable law, by the Participant’s guardian or legal representative) or by the person to whom the Participant’s rights pass by will or the laws of descent or by the designation of a beneficiary. However, notwithstanding these restrictions, a Participant may assign or transfer an Award, other than an ISO, pursuant to a court authorized or approved domestic relations order. All of our Common Shares subject to an Award and evidenced by a share certificate will contain a legend referencing the restrictions on the transferability of the Common Shares pursuant to the terms of the A&R LTIP. If Common Shares are issued in book entry form, a notation to the same restrictive effect will be placed on the transfer agent’s books in connection with such Common Shares.

All Awards under the A&R LTIP will be subject to any written clawback policy adopted by the Company, as in effect from time to time.

Unless earlier terminated by action of the Board, the A&R LTIP will terminate on May 30, 2033. Awards granted before the termination date of the A&R LTIP will continue to be effective according to their terms and conditions.

No fractional Common Shares will be issued or delivered pursuant to the A&R LTIP or any Award thereunder. The Administrator will determine whether cash, other securities or other property will be paid or transferred in lieu of any fractional Common Shares or whether those fractional Common Shares or any rights thereto will be cancelled, terminated or otherwise eliminated.

If the date under any Award on which: (i) cash is to be issued in settlement of the Award, or (ii) performance criteria are to be evaluated by the Company, occurs during a “blackout period” (as defined in the Company’s insider trading policy) applicable to the relevant Participant, or within three business days of the expiry of a blackout period applicable to the relevant Participant, then the settlement date or evaluation date, as applicable, will be deemed to be the tenth business day after expiry of the blackout period, or such earlier date following the expiry of the blackout period as determined by the Administrator. Awards described in the preceding sentence will be settled during a blackout period in order to comply with applicable U.S. and Canadian tax laws or exemptions therefrom.

The following is a general summary of the material Canadian federal income tax considerations, based on the current provisions of the Income Tax Act (Canada) and the regulations thereto (collectively, the “ITA”), to Participants who, at all relevant times and for purposes of the ITA: (i) are resident in Canada, (ii) are granted Awards by virtue of their employment with the Company or an affiliate, (iii) hold any Common Shares acquired pursuant to the settlement of an Award as capital property, and (iv) deal at arm’s length with, and are not affiliated with, the Company or any affiliate (each, a “Canadian Participant” for purposes of this section “Certain Canadian Federal Income Tax Considerations”). Common Shares will generally be considered to be capital property to a Canadian Participant unless such shares are held in the course of carrying on a business of trading or dealing in securities or are acquired in a transaction or transactions which may be considered to be an adventure or concern in the nature of trade.

This summary is of a general nature only and is not exhaustive of all possible Canadian federal income or other tax considerations that may apply to an Award. This summary is provided for general information only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Participant. No representations are made with respect to the income tax consequences to any particular Participant. This summary does not cover provincial, local, or foreign tax treatment for Participants and does not discuss any

tax implications to Participants who receive Awards by virtue of a consulting relationship. Participants should consult their own tax advisors for advice with respect to the income tax consequences of Awards in their particular circumstances, including the application and effect of the income and other tax laws of any applicable country, province, state or local tax authority. This summary does not describe the tax considerations applicable to the transfer of Awards. Participants should consult their own tax advisors.

For the purposes of the ITA, each amount relating to the benefit realized pursuant to an Award, and each amount relating to Common Shares, including adjusted cost base, dividends, and proceeds of disposition, must be expressed in Canadian dollars. Any amount denominated in U.S. dollars must be converted into Canadian dollars, which will generally be done at the exchange rate quoted by the Bank of Canada on the date the amount arose. Employees that are Canadian Participants may realize income, gains, or losses by virtue of changes in foreign currency exchange rates.

The A&R LTIP provides that all Options granted to Canadian Participants will be exercisable only for the issuance by the Company of authorized and previously unissued Common Shares from treasury (subject to the right of a Participant to elect an alternative form of payment as set out in the applicable award agreement).

A Canadian Participant will not have taxable income upon the grant of an Option. At the time of exercising an Option, a Canadian Participant will recognize, as employment income (subject to withholding), the difference between the fair market value of the Common Shares at the time of acquisition less the exercise price paid. Provided that the exercise price of the Option is at least equal to the fair market value of the underlying Common Shares at the time the Option was granted and the Common Shares constitute “prescribed shares” (within the meaning of section 6204 of the regulations to the ITA), a Canadian Participant who exercises an Option should be entitled to a deduction of 50% of the taxable amount on exercise, subject to limitations in the proposed amendments to the ITA which may restrict the availability of the deduction to Options covering a maximum of fair market value of CAD $200,000 of shares that vest each year. Each Canadian Participant should consult his or her own financial advisor regarding the availability of such deduction.

If, instead of exercising an Option, a Canadian Participant elects to surrender an Option pursuant to the exercise of a SAR granted in tandem with the Option, the tax results for the Canadian Participant will generally be the same as if the Canadian Participant had exercised the Option, provided that a Canadian Participant will only be entitled to the 50% deduction described above if, in addition to the satisfaction of the above requirements, the Company makes an election under subsection 110(1.1) of the ITA to not claim any deduction associated with the payment.

The tax cost to a Canadian Participant of Common Shares acquired on the exercise or surrender of an Option will be equal to the fair market value of the Common Shares at the time of acquisition. The cost of the Common Shares must be averaged with the adjusted cost base of all other Common Shares held by the Canadian Participant as capital property to determine the adjusted cost base on a per share basis.

Neither the Company nor any of its affiliates will generally be entitled to a tax deduction upon the issuance of Common Shares to a Canadian Participant pursuant to the exercise or surrender of an Option to the extent that the Canadian Participant is entitled to the 50% deduction described above. The Company may be entitled to a tax deduction where the Canadian Participant is not entitled to the 50% deduction described above by virtue of the application of the CAD$200,000 limit described above provided the Company has satisfied certain compliance requirements. The Company or affiliate that makes a cash payment upon the surrender of an Option pursuant to the exercise of a SAR granted in tandem with the Option should generally be entitled to a deduction, provided that the amount of the cash payment is reasonable and the Company has not made an election under subsection 110(1.1) of the ITA.

The A&R LTIP provides that the grant price per Common Share subject to a SAR shall not be less than the fair market value per share as of the date of grant of that SAR, that all SARs granted to a Canadian Participant shall be granted solely in respect of the services of such Canadian Participant to be rendered to the Company and its affiliates subsequent to the date of grant of the SAR, and that any SAR granted to a Canadian Participant shall have a term extending not later than December 15th of the calendar year in which such SAR becomes vested and exercisable.

A Canadian Participant will not have taxable income upon the grant of a SAR. At the time of exercising a SAR, a Canadian Participant will recognize, as employment income (subject to withholding), the amount of the cash payment received or the fair market value of the Common Shares at the time of acquisition.

The tax cost to a Canadian Participant of Common Shares, if any, acquired on the exercise of a SAR will be equal to the fair market value of the Common Shares at the time of acquisition. The cost of the Common Shares must be averaged with the adjusted cost base of all other Common Shares held by the Canadian Participant as capital property to determine the adjusted cost base on a per share basis.

The Company or affiliate that makes a payment upon the exercise of a SAR should generally be entitled to a deduction, provided that the amount of the payment is reasonable.

An income inclusion will generally arise to a Canadian Participant at the time of an Award of Restricted Shares or a Share Award under the A&R LTIP. The Canadian Participant will recognize employment income (subject to withholding) equal to the fair market value of the Common Shares received, which may reflect a discount for the risk of forfeiture and restrictions on the sale of the Restricted Shares, less the purchase price, if any, paid by such Canadian Participant for the Common Shares.

The tax cost to a Canadian Participant of Common Shares acquired pursuant to an Award of Restricted Shares or a Share Award will be equal to the fair market value of the shares at the time of acquisition. The cost of the Common Shares must be averaged with the adjusted cost base of all other Common Shares held by the Canadian Participant as capital property to determine the adjusted cost base on a per share basis.

The availability to the Company or any affiliate of a tax deduction upon the issuance of Common Shares to a Canadian Participant pursuant to an Award of Restricted Shares or a Share Award will depend on the circumstances surrounding the particular Award.

The A&R LTIP provides that Restricted Share Units and DSUs granted to Canadian Participants are to have such terms and conditions as are necessary so that the Restricted Share Units or DSUs, as applicable, are exempt from, the definition of “salary deferral arrangement” in the ITA.

Canadian Participants will not have taxable income upon the grant of Restricted Share Units or DSUs. Upon the future payment being made in respect of the Restricted Share Units or DSUs, whether in cash or Common Shares, a Canadian Participant will recognize, as employment income (subject to withholding), the amount of the cash payment received or the fair market value of the Common Shares at the time of acquisition.

The tax cost to a Canadian Participant of Common Shares, if any, acquired on the settlement of a Restricted Share Unit or DSU, as the case may be, will be equal to the fair market value of the shares at the time of acquisition. The cost of the Common Shares must be averaged with the adjusted cost base of all other Common Shares held by the Canadian Participant as capital property to determine the adjusted cost base on a per share basis.

The Company or applicable affiliate will generally be entitled to deduct the amount of any payment made in settlement of a Restricted Share Unit or DSU, provided such amount is reasonable.

The Canadian federal income tax consequences to a Canadian Participant on the grant, holding or settlement of an Other Share-Based Award will depend on the form, terms and conditions of such Award. Canadian Participants who receive an Other Share-Based Award should consult with their own tax advisors.

A Canadian Participant will recognize, as employment income (subject to withholding), the amount of the cash payment received upon the grant of any Cash Award.

The Company or applicable affiliate will generally be entitled to deduct the amount of any payment made in settlement of a Cash Award, provided such amount is reasonable.

A Canadian Participant who disposes of a Common Share (other than as a result of a redemption or repurchase of such share by the Company), including on a deemed disposition on death, will realize a capital gain (or capital loss) equal to the amount by which the actual or deemed proceeds of disposition exceed (or are exceeded by) the Canadian Participant’s adjusted cost base of the share and any reasonable costs of disposition.

The following discussion is for general information only and is intended to briefly summarize the United States federal income tax consequences to Participants arising from participation in the A&R LTIP. This description is based on current law, which is subject to change (possibly retroactively). The tax treatment of a Participant in the A&R LTIP may vary depending on his or her particular situation and may, therefore, be subject to special rules not discussed below. No attempt has been made to discuss any potential state or local tax consequences or federal tax consequences in jurisdictions outside of the United States. In addition, Nonstatutory Options and SARs with an exercise price less than the fair market value of our Common Shares on the date of grant, SARs payable in cash, Restricted Share Units and certain other Awards that may be granted pursuant to the A&R LTIP, could be subject to additional taxes unless they are designed to comply with certain restrictions set forth in Section 409A of the Code and the guidance promulgated thereunder.

Participants will not realize taxable income upon the grant of an Option or SAR. Upon the exercise of a Nonstatutory Option or a SAR, a Participant will recognize ordinary compensation income (subject to the Company’s withholding obligations if an employee) in an amount equal to the excess of (i) the amount of cash and the fair market value of our Common Shares received, over (ii) the exercise price of the Award. A Participant will generally have a tax basis in any Common Shares received pursuant to the exercise of a Nonstatutory Option or SAR that equals the fair market value of such shares on the date of exercise. Subject to the discussion under “Federal U.S. Tax Consequences to the Company” below, the Company will be entitled to a deduction for federal income tax purposes that corresponds as to timing and amount with the compensation income recognized by a Participant under the foregoing rules. When a Participant sells our Common Shares acquired as a result of the exercise of a Nonstatutory Option or SAR, any appreciation (or depreciation) in the value of such Common Shares after the exercise date is treated as long- or short-term capital gain (or loss) for federal income tax purposes, depending on the holding period. Our Common Shares must be held for more than 12 months to qualify for long-term capital gain treatment.

Participants eligible to receive an ISO will not recognize taxable income on the grant of an ISO. Upon the exercise of an ISO, a Participant will not recognize taxable income, although the excess of the fair market value of our Common Shares received upon exercise of the ISO (“ISO Shares”) over the exercise price will increase the alternative minimum taxable income of the Participant, which may cause such Participant to incur alternative minimum tax. The payment of any alternative minimum tax attributable to the exercise of an ISO would be allowed as a credit against the Participant’s regular tax liability in a later year to the extent the Participant’s regular tax liability is in excess of the alternative minimum tax for that year.

Upon the disposition of an ISO Share that has been held for the required holding period (generally, at least two years from the date of grant and one year from the date of exercise of the ISO), a Participant will generally recognize capital gain (or loss) equal to the excess (or shortfall) of the amount received in the disposition over the exercise price paid by the Participant for the ISO Share. However, if a Participant disposes of an ISO Share that has not been held for the requisite holding period (a “Disqualifying Disposition”), the Participant will recognize ordinary compensation income in the year of the Disqualifying Disposition in an amount equal to the amount by which the fair market value of the ISO Share at the time of exercise of the ISO (or, if less, the amount realized in the case of an arm’s length disposition to an unrelated party) exceeds the exercise price paid by the Participant for such ISO Share. A Participant would also recognize capital gain to the extent the amount realized in the Disqualifying Disposition exceeds the fair market value of the ISO Share on the exercise date. If the exercise price paid for the ISO Share exceeds the amount realized (in the case of an arm’s-length disposition to an unrelated party), such excess would ordinarily constitute a capital loss.

The Company will generally not be entitled to any federal income tax deduction upon the grant or exercise of an ISO, unless a Participant makes a Disqualifying Disposition of the ISO Share. If a Participant makes a Disqualifying Disposition, the Company will then, subject to the discussion below under “Federal U.S. Tax Consequences to the Company,” be entitled to a tax deduction that corresponds as to timing and amount with the compensation income recognized by a Participant under the rules described in the preceding paragraph.

Under current rulings, if a Participant transfers previously held shares of our Common Shares (other than an ISO Share that has not been held for the requisite holding period) in satisfaction of part or all of the exercise price of an Option, whether a Nonstatutory Option or an ISO, no additional gain will be recognized on the transfer of such previously held shares in satisfaction of the Nonstatutory Option or ISO exercise price (although a Participant would still recognize ordinary compensation income upon exercise of a Nonstatutory Option in the manner described above). Moreover, that number of our Common Shares received upon exercise which equals the number of previously held Common Shares surrendered in satisfaction of the Nonstatutory Option exercise price will have a tax basis that equals, and a capital gains holding period that includes, the tax basis and capital gains holding period of the previously held Common Shares surrendered in satisfaction of the Nonstatutory Option exercise price. Any additional Common Shares received upon exercise will have a tax basis that equals the amount of cash (if any) paid by the Participant, plus the amount of compensation income recognized by the Participant under the rules described above.

The A&R LTIP generally prohibits the transfer of Awards other than by will or according to the laws of descent and distribution or pursuant to a domestic relations order, but the A&R LTIP allows the Administrator to permit the transfer of Awards (other than ISOs) in limited circumstances, in its discretion. For income and gift tax purposes, certain transfers of Nonstatutory Options should generally be treated as completed gifts, subject to gift taxation.

The United States Internal Revenue Service (the “IRS”) has not provided formal guidance on the income tax consequences of a transfer of Nonstatutory Options (other than in the context of divorce) or SARs. However, the IRS has informally indicated that after a transfer of share options (other than in the context of divorce pursuant to a domestic relations order), the transferor will recognize income, which will be subject to withholding, and employment or payroll taxes will be collectible at the time the transferee exercises the share options. If a Nonstatutory Option is transferred pursuant to a domestic relations order, the transferee will recognize ordinary income upon exercise by the transferee, which will be subject to withholding, and employment or payroll taxes (attributable to and reported with respect to the transferor) will be collectible from the transferee at such time.

In addition, if a Participant transfers a vested Nonstatutory Option to another person and retains no interest in or power over it, the transfer is treated as a completed gift. The amount of the transferor’s gift (or generation-skipping transfer, if the gift is to a grandchild or later generation) equals the value of the Nonstatutory Option at the time of the gift. The value of the Nonstatutory Option may be affected by several factors, including the difference between the exercise price and the fair market value of the share, the potential for future appreciation or depreciation of our Common Shares, the time period of the Nonstatutory Option and the illiquidity of the Nonstatutory Option. The transferor will be subject to a federal gift tax, which will be limited by (i) the annual exclusion of U.S. $18,000 per donee (for 2024, subject to adjustment in future years), (ii) the transferor’s lifetime unified credit, or (iii) the marital or charitable deductions. The gifted Nonstatutory Option will not be included in the Participant’s gross estate for purposes of the federal estate tax or the generation-skipping transfer tax.

This favorable tax treatment for vested Nonstatutory Options has not been extended to unvested Nonstatutory Options. Whether such consequences apply to unvested Nonstatutory Options or to SARs is uncertain and the gift tax implications of such a transfer is a risk the transferor will bear upon such a disposition.

Restricted Shares; Restricted Share Units; Share Awards; Other Share-Based or Cash Awards; DSUs

A Participant will recognize ordinary compensation income upon receipt of cash pursuant to a Cash Award or, if earlier, at the time the cash is otherwise made available for the Participant to draw upon. Individuals will not have taxable income at the time of grant of Restricted Share Units or DSUs, but rather, will generally recognize ordinary compensation income at the time he or she receives cash or a Common Share in settlement of the Restricted Share Units or DSUs, as applicable, in an amount equal to the cash or the fair market value of the common share received.

A recipient of Restricted Shares or a Share Award generally will be subject to tax at ordinary income tax rates on the fair market value of the Common Shares when such Award is received, reduced by any amount paid by the recipient; however, if the Common Shares are not transferable and are subject to a substantial risk of forfeiture when received, a Participant will recognize ordinary compensation income in an amount equal to the fair market value of the Common Shares (i) when the Common Shares first become transferable and are no longer subject to a substantial risk of forfeiture, in cases where a Participant does not make a valid election under Section 83(b) of the Code, or (ii) when the Award is received, in cases where a Participant makes a valid election under Section 83(b) of the Code. If a Section 83(b) election is made and our Common Shares are subsequently forfeited, the Participant will not be allowed to take a deduction for the value of the forfeited Common Shares. If a Section 83(b) election has not been made, any dividends received with respect to Restricted Shares that are subject at that time to a risk of forfeiture or restrictions on transfer generally will be treated as compensation that is taxable as ordinary income to the Participant; otherwise the dividends will be treated as dividends.

A Participant who is a taxpayer in the United States will be subject to withholding for United States federal, and generally for state and local, income taxes at the time he or she recognizes income under the rules described above. The tax basis in our Common Shares received by a Participant will equal the amount recognized by the Participant as compensation income under the rules described in the preceding paragraph, and the Participant’s capital gains holding period in those Common Shares will commence on the later of the date such Common Shares are received or the restrictions lapse. Subject to the discussion below under “Federal U.S. Tax Consequences to the Company,” the Company will be entitled to a deduction for federal income tax purposes that corresponds as to timing and amount with the compensation income recognized by a Participant under the foregoing rules.

In order for the amounts described above to be deductible by the Company (or its subsidiary), such amounts must constitute reasonable compensation for services rendered or to be rendered and must be ordinary and necessary business expenses.

Our ability (or the ability of one of our subsidiaries) to obtain a deduction for future payments under the A&R LTIP could also be limited by the golden parachute rules of Section 280G of the Code, which prevent the deductibility of certain excess parachute payments made in connection with a change of control of an employer-corporation.

The ability of the Company (or its subsidiary) to obtain a deduction for amounts paid under the A&R LTIP could be limited by Section 162(m) of the Code. Section 162(m) of the Code limits the Company’s ability to deduct compensation, for federal income tax purposes, paid during any year to a “covered employee” (within the meaning of Section 162(m) of the Code) in excess of U.S. $1,000,000.

All Board retainers and fees for 2024 will be issued as DSUs rather than paid in cash. The Board will act each year to determine what portion of Board retainers will be issued as DSUs and what portion will be paid in cash for the immediately succeeding year. If the Board takes no action then all retainers and fees will be satisfied in the form of DSUs. If the Board elects to settle less than 100% of retainers and fees as DSUs then members of the Board may make a timely and irrevocable election to receive DSUs in lieu of cash retainers and fees. As a result, the number and value of DSUs that will be granted to Eligible Directors in future years is subject to the discretion of the Board and not currently determinable. Since the Board previously elected to pay all retainers and fees payable to the Board for 2024 in the form of DSUs, we have provided an estimate of DSUs that will be issued to members of the Board under the A&R LTIP during 2024. The value reported in this column represents the value of the retainers expected to be issued as DSUs during 2024 following the effectiveness of the A&R LTIP (assuming its adoption). It does not include the value of meeting fees as the number of meetings to be held during 2024 is not currently determinable.

The following table sets forth information about securities that may be issued under the outstanding equity compensation plans as of December 31, 2023.

The following table sets forth the annual burn rate of stock options, RSUs, PSUs and DSUs issued under the LTIP for the last three years.

(2)

During 2023, 2,584,161 PSUs, which may vest up to 190% of the target amount granted dependent on achievement of performance targets, were granted to certain executives. For the purposes of the burn rate calculation in the table above, it was assumed the 2,584,161 PSUs granted in 2023 vest at 190% of the target amount granted, resulting in the issuance of 4,909,907 Common Shares. If the PSUs were to vest at 100%, 2,584,161 Common Shares would be issued on settlement of such PSUs, resulting in a burn rate under the LTIP in 2023 of 8.34%. Of the 2,584,161 PSUs granted in 2023, Mr. Little forfeited 738,553 PSUs on his departure in August 2023. The burn rate calculation also assumes that all 1,795,974 DSUs granted under the LTIP after May 30, 2023, will be settled in Common Shares.

The A&R LTIP will not be implemented unless the A&R LTIP Resolution is approved by our shareholders. If the A&R LTIP Resolution is not approved by our shareholders, then the LTIP will remain in place as currently drafted:

(i)

the maximum number of Common Shares reserved and available for issuance upon the settlement, exercise or redemption, as applicable, of Awards will remain equal to 12,350,000 plus the number of our Common Shares subject to stock options previously granted under the Option Plan that expire or for any reason are canceled or terminated after May 22, 2020 without having been exercised in full, and the Company will continue to grant awards under the LTIP until such current share reserve is exhausted. As of the Record Date, there were 1,011,741 Common Shares reserved and available for issuance upon the settlement, exercise or redemption of Awards, as applicable, granted under the LTIP, subject to the applicable recycling provisions of the LTIP. If the A&R LTIP Resolution is not approved, once such share reserve is exhausted, the Company may elect to provide compensation through other means, such as cash-settled awards or other cash compensation, to assure that the Company and its affiliates can attract and retain qualified personnel.

At the Meeting, or any adjournment or postponement thereof, our shareholders will be asked to pass A&R LTIP Resolution, authorizing the adoption of the A&R LTIP, attached as Appendix A to this Proxy Statement, to increase the number of Common Shares reserved and available for issuance under the LTIP, as set out below:

the adoption of the DIRTT Environmental Solutions Ltd. Second Amended & Restated Long Term Incentive Plan (the “A&R LTIP”), attached as Appendix A to the Management Information Circular and Proxy Statement of DIRTT Environmental Solutions Ltd. (the “Company”) dated March 27, 2024 in respect of the Company's annual and special meeting of holders of common shares in the capital of the Company (“Common Shares”) scheduled to be held on May 9, 2024 is hereby authorized and approved, which increases the aggregate number of Common Shares reserved and available for issuance by 15,000,000, such that the total Common Shares reserved under the A&R LTIP will increase from 12,350,000 to 27,350,000 plus such number of Common Shares that may be issued under A&R LTIP in respect of stock options previously granted under the Amended and Restated Incentive Stock Option Plan of the Company that expire or for any reason are cancelled or terminated without having been exercised in full following May 22, 2020, is hereby authorized and approved, ratified and confirmed, and 27,350,000 of such Common Shares will be available for issuance upon the exercise of incentive stock options, within the meaning of Section 422 of the U.S. Internal Revenue Code;

The Board is committed to the highest standards of corporate governance practices. The Board believes that this commitment is not only in the best interest of shareholders but that it also promotes effective decision-making at the Board level. In establishing its corporate governance practices, the Board has been guided by (i) the applicable securities laws of Canada, including National Policy 58-201 - Corporate Governance Guidelines and National Instrument 52-110 - Audit Committees (“NI-52-110”), (ii) the applicable securities laws of the United States, including under the U.S. Securities and Exchange Act of 1934, as amended (the “Exchange Act”), and (iii) consideration of corporate governance trends in Canada and the United States.

Our business and affairs are managed under the direction of our Board, which currently consists of eight members. Each director is elected to serve until the close of the next annual meeting of shareholders of the Company or until his or her successor is duly elected or appointed. Our current by-laws provide that the number of directors may be determined by resolution of the Board.

Under the requirements of applicable securities laws of Canada and the Company’s Board Mandate and Corporate Governance Guidelines independent directors must comprise a majority of our Board. Audit Committee members must also satisfy the independence criteria set forth in NI 52-110. Under applicable securities laws of Canada, a director will qualify as an “independent director” only if, in the opinion of that company’s board, that person does not have a direct or indirect relationship that would be reasonably expected to interfere with the exercise of such's independent judgment in carrying out the responsibilities of a director.

Our Board has undertaken a review of its composition, the composition of its committees and independence of each director and director nominee. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including family relationships, our Board has determined that Douglas Edwards, Aron English, Shaun Noll, Shally Pannikode, Scott Robinson, Scott Ryan and Ken Sanders, representing a majority of our directors, do not have any relationships that would be reasonably expected to interfere with the exercise of independent judgment in carrying out the responsibilities of a director or in the best interest of the Company and that each of these directors is “independent” as that term is defined under applicable securities laws of Canada. Benjamin Urban is not considered independent because he is the Chief Executive Officer of the Company.

Our Board also determined that Messrs. Robinson, Edwards and Ryan, who comprise our audit committee (“Audit Committee”), and Messrs. English, Noll and Sanders, who comprise our corporate governance and compensation committee (“Corporate Governance and Compensation Committee”), satisfy the independence standards for those committees established by applicable securities laws of Canada. In making the above determinations, our Board considered the current and prior relationships that each non-employee director has with the Company and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our share capital by each non-employee director and the transactions involving each non-employee director, if any, described in “Certain Relationships and Related Party Transactions.”

The Board is responsible for the stewardship of the Company which includes satisfying itself as to the integrity of the Chief Executive Officer and other executive officers, developing and adopting a strategic planning process, identifying the principal risks of the Company’s business and ensuring implementation of systems to manage these risks, overseeing the Company’s succession planning, adopting a communication policy, monitoring the Company’s internal control and management information systems, and developing the Company’s approach to corporate governance.

The Board has developed a written Board Mandate and Corporate Governance Guidelines, which is attached as Appendix B to this Proxy Statement.

The Board has developed written position descriptions for the Chair of the Board and the Chief Executive Officer. The Board has not developed separate written position descriptions for the chair of each committee of the Board. Instead, the Board has adopted written charters for each Board committee that outline the responsibilities of each committee chair. The position descriptions for the Chair of the Board and the committee charters are available on our website at www.dirtt.com/investors/leadership-and-governance.

Mr. Sanders, an independent director, serves as the Chair of our Board. In that role, Mr. Sanders presides over the executive sessions of the Board in which Mr. Urban, our Chief Executive Officer, does not participate. Mr. Sanders also serves as a liaison to management on behalf of the independent members of the Board. Our Board has concluded that our current leadership structure is appropriate at this time. Our Board will periodically review our leadership structure and may make such changes in the future as it deems appropriate.

The following table shows the record of attendance by incumbent directors at Board and committee meetings for the year ended December 31, 2023. Each director, other than Shalima Pannikode, who was appointed to the Board in March 2024, attended at least 71 % of the aggregate of the meetings of the Board and meetings of the committees of which he or she was a member in the portion of our last fiscal year during which such person was a director. The Board encourages all directors to attend the annual meeting of shareholders, if practicable. At the 2023 annual and special meeting of shareholders, seven of the incumbent directors attended the meeting.

The Board and its committees generally conduct in-camera sessions (i.e., executive sessions) during each Board meeting, at which no executive directors or members of management are present. The in-camera sessions are intended to encourage the Board and its committees to fully and independently fulfill their mandates or charters and to facilitate the performance of the fiduciary duties and responsibilities of the Board and its committees on behalf of shareholders. Since the beginning of 2023, the Board held no meetings at which non-independent directors were not present.

Our Board has established an Audit Committee, a Corporate Governance and Compensation Committee and an Enterprise Risk Management Committee. Our Board may, from time to time, establish other committees to facilitate the management of our business. The following sections describe the composition and functions of each committee. Members serve on these committees until their resignation or until otherwise determined by our Board.

Our Audit Committee consists of Scott Robinson (Chair), Douglas Edwards and Scott Ryan. Our Board has determined that Messrs. Robinson, Edwards and Ryan are independent and financially literate under applicable securities laws of Canada.

Our Board has determined that Mr. Robinson is an “audit committee financial expert” within the meaning of SEC regulations.

The Board has adopted a written charter setting forth the responsibilities, powers and operations of the Audit Committee, which is available on our website at www.dirtt.com/investors/leadership-and-governance. The Audit Committee is responsible for assisting the Board in fulfilling its oversight responsibilities in relation to:

The Audit Committee has the authority to engage independent counsel and other advisors as it determines necessary to carry out its duties and to determine the compensation of such advisors. The Audit Committee meets at least four times annually and met a total of four times in the year ended December 31, 2023.

Our Corporate Governance and Compensation Committee consists of Aron English (Chair), Douglas Edwards, Shaun Noll and Ken Sanders. Our Board has determined that Messrs. English, Edwards, Noll and Sanders are independent under the applicable securities laws in Canada. Each is a “non-employee director” as defined in Rule 16b-3 under the Exchange Act.

The Board has adopted a written charter setting forth the responsibilities, powers and operations of the Corporate Governance and Compensation Committee, which is available on our website at www.dirtt.com/investors/leadership-and-governance. The Corporate Governance and Compensation Committee is responsible for assisting the Board in fulfilling its oversight responsibilities in relation to:

The Corporate Governance and Compensation Committee has the authority to engage independent counsel and other advisors as it determines necessary to carry out its duties and to determine the compensation of such advisors. The Corporate Governance and Compensation Committee may delegate its authority to a subcommittee of the Corporate Governance and Compensation Committee. In assessing performance of executive officers (other than the Chief Executive Officer), the Corporate Governance and Compensation Committee considers the Chief Executive Officer’s review of those executive officers’ performance and recommendations regarding their compensation. The Corporate Governance and Compensation Committee meets at least twice annually and met a total of four times in the year ended December 31, 2023.

Our Enterprise Risk Management Committee consists of Scott Ryan (Chair), Shaun Noll, Scott Robinson, and Shalima Pannikode.

The Board has adopted a written charter setting forth the responsibilities, powers and operations of the Enterprise Risk Management Committee, which is available on our website at www.dirtt.com/investors/leadership-and-governance. The Enterprise Risk Management Committee is responsible for assisting the Board in fulfilling its oversight responsibilities in relation to:

The Enterprise Risk Management Committee has the authority to engage independent counsel and other advisors as it determines necessary to carry out its duties and to determine the compensation of such advisors. The Enterprise Risk Management Committee meets at least twice annually and met a total of four times in the year ended December 31, 2023.

At each meeting, the Enterprise Risk Management Committee receives reports from management regarding, among other things, risk exposures of the Company (including financial risks and risks related to information security, cybersecurity and data protection) and the steps management takes to monitor and control these exposures.

We have a comprehensive program for identifying and mitigating information and cybersecurity risks, enhancing the skills of our people, our processes and technology aspects of the Company. In particular, we use automated software and hardware solutions to protect our on-premise and cloud infrastructure; conduct routine third-party evaluations and vulnerability testing to identify and mitigate risks; and deploy ongoing information security training and awareness programs throughout the Company. We also maintain cybersecurity insurance of the types and amounts considered commercially prudent and consistent with industry practice.

With respect to cybersecurity, our Cybersecurity team performs periodic risk assessments and, on a quarterly basis, provides the Enterprise Risk Management Committee information related to the Company’s cybersecurity, including statistics on attempted cyber-attacks, status of employee information security training awareness, and information on any security investigations. The Cybersecurity team advises the Enterprise Risk Management Committee of significant global cyber events that occurred during the quarter and whether they impacted the Company. The Cybersecurity team regularly discusses with the Enterprise Risk Management Committee the Company’s cybersecurity posture and whether the Company should implement additional protections and controls to assist the Company in protecting, responding to, or mitigating potential future cyber-attacks.

ESG oversight is conducted from the highest levels of the Company’s organization. The Enterprise Risk Management Committee has been tasked with specific oversight with respect to corporate responsibility and sustainability, including environmental, social and other public issues of significance to the Company and its stakeholders, and reviews management’s assessments of such strategy, initiatives and policies. The Company issued ESG reports in 2021 and 2022 and continues to work towards achieving various objectives outlined therein. The Company is evaluating its current ESG goals, including those relating to environmental sustainability and diversity and inclusion, and will present those in its 2023 ESG report later this year. Among other things, the Enterprise Risk Management Committee receives reports from management regarding the Company’s ESG objectives, the steps management takes to monitor compliance, and current ESG trends.

The Board has overall responsibility for the oversight of the Company’s risk management process, which is designed to support the achievement of organizational objectives, including strategic objectives, improve long-term organizational performance and enhance shareholder value. The Board also established the Enterprise Risk Management Committee and delegated certain responsibilities for risk oversight to the committee. Risk management includes not only understanding Company-specific risks and the steps management implements to manage those risks, but also what level of risk is acceptable and appropriate for the Company. Management is responsible for establishing our business strategy, identifying and assessing the related risks and implementing appropriate risk management practices. The Board and the Enterprise Risk Management Committee periodically review our business strategy and management’s assessment of the related risks and discusses with management the appropriate level of risk for the Company. Each of our Board committees also oversees the management of risk that falls within that committee’s areas of responsibility. For example, the

Audit Committee assists the Board in fulfilling its risk oversight responsibilities relating to our financial and accounting risk management policies and procedures. As part of this process, the Audit Committee meets periodically with management to review, discuss and provide oversight with respect to our processes and controls to assess, monitor and mitigate potential risk exposure. In providing such oversight, the Audit Committee may also discuss such processes and controls with our independent registered public accounting firm. The Corporate Governance and Compensation Committee likewise assists the Board in fulfilling its risk oversight responsibilities associated with, among other things, compensation program design (by reviewing whether there are risks arising from our compensation programs and practices that are reasonably likely to have a material adverse effect on us), as well as risk management relating to corporate governance, Board organization and Board membership.

The Board has not established term limits for directors and believes such limits can result in the loss of valuable, experienced directors solely on the basis of age or length of service. Under the leadership of the Corporate Governance and Compensation Committee, an annual performance evaluation process is in place to ensure adequate Board renewal. This annual process evaluates the tenure and performance of individual directors and reviews the composition and effectiveness of the Board and its committees. Assessments include, among other things, a skills matrix that helps the Corporate Governance and Compensation Committee and the Board assess whether the Board possesses the appropriate experience, expertise and business and operational insight for the effective stewardship of the Company. The Corporate Governance and Compensation Committee also oversees an annual confidential evaluation of each director regarding his or her views on the effectiveness of the Board, its committees and the Chair. Recommendations resulting from the evaluation are also used to enhance Board composition and improve Board effectiveness.

As discussed above, the Corporate Governance and Compensation Committee believes that our Board’s membership should represent a diversity of backgrounds, experience and skills. To this end, the Corporate Governance and Compensation Committee has established a skills matrix outlining the skills and experiences which they believe are most relevant for the Company. This process informs the Board’s succession planning process by identifying any gaps in the competencies required. The Corporate Governance and Compensation Committee reviews annually and updates as necessary the skills matrix.

The Board is committed to a process of ongoing Board development and renewal to ensure the Board as a whole, can add significant value to the current and long-term goals of the Company. The Corporate Governance and Compensation Committee is composed entirely of independent directors and is mandated by the Board to identify and assess potential Board candidates to fill perceived needs on the Board for required skills, expertise, independence and other factors. In reviewing potential nominees, the Corporate Governance and Compensation Committee considers the qualifications of each potential nominee in light of the Board’s existing and desired mix of experience and expertise. Specifically, the Corporate Governance and Compensation Committee considers each potential nominee’s (i) relevant experience, skills, qualifications and contributions, including to any Board committees on which the director may serve; (ii) past Board and committee meeting attendance and performance; (iii) length of Board service or service on boards of directors of other companies; (iv) personal and professional integrity; (v) independence under the standards of applicable securities laws and exchange rules; and (vi) responsibilities that would materially interfere with or be incompatible with Board membership. After reviewing the qualifications of potential Board candidates, the Corporate Governance and Compensation Committee presents its recommendations to the Board, which selects the final director nominees. The Company did not pay any fees to any third parties to identify or assist in identifying or evaluating the nominees for the Meeting.

The Corporate Governance and Compensation Committee considers shareholder nominees using these same criteria. Shareholders who wish to present a potential nominee to the Corporate Governance and Compensation Committee for consideration for election at a future annual meeting of shareholders must provide the Corporate Governance and Compensation Committee with notice of the recommendation and certain information regarding the candidate as described in our current by-laws and within the time periods set forth under the caption “Shareholder Proposals.”

Pursuant to the Support Agreement, the Company has agreed to nominate Mr. English (or a replacement director to be identified by 22NW Fund) for election as a director at the annual general meeting of the Company in each of 2024 and 2025 (the “2024 Meeting” and “2025 Meeting,” respectively). Subject to certain exceptions, 22NW Fund has agreed to vote all of their Common Shares in favor of recommendations of the Board on director election proposals through the 2025 Meeting. For additional information, see “Certain Relationship and Related Party Transactions – Transactions with Related Parties.”

Our Corporate Governance and Compensation Committee and Board monitor governance developments in Canada and the United States, including those relating to diversity. We support the objectives of increasing diversity and in particular the representation of women on the Board and in executive officer positions.

The Board adopted an updated formal diversity and inclusion policy on February 21, 2024. The policy sets aspirational targets to achieve diversity, with the goal of having at least 20% female directors by the 2025 annual general meeting of shareholders and at least two directors from an ethnic minority background at all times. Additionally, the Corporate Governance and Compensation Committee will regularly review Board composition, succession planning and talent development having regards to diversity objectives, identify candidates for the Board while having regards to diversity in promoting the success of the Company, and work with search firms who will promote the Company’s values and approach to diversity in identifying and proposing suitable candidates for Board appointment, including, ensuring that at least 50% of candidates for the Board will be qualified women and/or people from racial or ethnic minority backgrounds.

The Corporate Governance and Compensation Committee and the Board are also responsible for establishing measurable objectives for achieving gender diversity and annually assessing the Company’s achievement against diversity objectives. The Board previously established an objective to have 30% female representation on the Board by 2022, which was achieved. One of this year’s nominated directors is female, and two of this year’s nominated directors are a racial or ethnic minority.

The Company aims to have a meaningful representation of women in executive officer positions; however, it has not established numeric targets for representation of women in executive officer positions at this time. We believe that a less formulaic approach, together with a rigorous search for qualified candidates, will best serve our needs. The Company believes it is paramount to maintain flexibility in the hiring process to ensure that the most qualified available candidates are selected based on the Company’s objectives and challenges. In identifying suitable candidates for executive officer positions, the Company will consider candidates on merit using objective criteria and with due regard for the benefits of diversity. Currently, there is one woman in an executive officer position (representing 1/3 of executive officers). We recognize the importance of diversity and believe that the Company is strengthened by advancing women in leadership roles. In this regard, we are actively reviewing our hiring, professional development and other business practices to ensure that they are effective in promoting diversity. By doing so, we believe our Board and executive officers will be armed with a broad range of perspectives, experience and expertise that is better positioned to provide effective stewardship and fulfill their duties to the Company, its employees and shareholders.

The Corporate Governance and Compensation Committee develops and oversees the execution of orientation and continuing education programs for new and existing directors of the Company, respectively. Orientation programs utilized to on-board new directors are tailored to the needs and areas of expertise of the individual and focus on providing new directors with:

These programs are aimed to inform directors as to matters affecting, or that may affect, the Company’s strategies, major risks and operations and to keep directors informed and updated regarding their duties and obligations as directors.

Messrs. English, Edwards, Noll and Sanders served on our Corporate Governance and Compensation Committee during the last year. Mr. Edwards assumed a role on the Compensation and Governance Committee effective May 30, 2023. None of the members of the Corporate Governance and Compensation Committee is currently or has been at any time an officer or employee of the Company. None of our executive officers currently serves, or has served during the last year, as a member of the board or compensation committee of any entity that has one or more executive officers serving as a member of our Board or Corporate Governance and Compensation Committee.

The Company has adopted a Code of Ethics for its directors, officers, and employees. The Code of Ethics addresses, among other things, conflicts of interest, honest and ethical conduct, the full, fair, accurate, timely and understandable disclosure in periodic reports and other public documents, compliance with applicable laws, rules and regulations (including insider trading laws) and the reporting of violations of the Code of Ethics. All directors, officers, and employees are required to report violations of the Code of Ethics in accordance with the procedures set forth therein and in the Company’s Integrity Policy (i.e., whistleblower policy). The Code of Ethics prohibits retaliation against employees who report suspected misconduct in good faith. The Integrity Policy also promotes, among other things, the disclosure and reporting of any questionable accounting or auditing matters, fraudulent or misleading financial information, and any allegations of misconduct involving Board members or executive officers. The Audit Committee will periodically review the Code of Ethics and oversee its enforcement. A copy of our Code of Ethics can be found on our website at www.dirtt.com/investors/leadership-and-governance and on SEDAR+ at www.sedarplus.ca.

Each director must disclose all actual or potential conflicts of interest and refrain from voting on matters in which such director has a conflict of interest. In addition, the director must recuse himself or herself from any discussion or decision on any matter in which the director is precluded from voting as a result of a conflict of interest. Directors, officers, employees and contractors are encouraged to terminate any relationship or interest that gives rise to a conflict of interest that cannot be resolved. In addition, directors, officers, employees and contractors are encouraged to disclose all opportunities to dispose of conflicting interests before any difficulty arises.

The Corporate Governance and Compensation Committee will make recommendations to the Board regarding all proposed related party transactions and situations involving any potential conflict of interest that is not required to be dealt with by an “independent special committee” pursuant to applicable securities regulations or other governing laws.

We have also developed and adopted an insider trading policy for our directors, officers, employees, and contractors (the “Insider Trading Policy”). The Insider Trading Policy promotes proper trading practices in our Common Shares in accordance with applicable securities regulations or other governing laws.

Pursuant to the Company’s Insider Trading Policy, all directors, officers and other employees of the Company or any of its subsidiaries, along with their immediate family members, other members of their households and entities or trusts that are controlled by any such individual, are prohibited from (i) making any short sales of any securities of the Company, (ii) engaging in transactions involving Company-based derivative securities (other than equity-based compensation), or (iii) otherwise engaging in any other

transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s Common Shares, including through prepaid variable forward contracts and exchange funds. “Short sales” are sales of securities that the seller does not own at the time of the sale or, if owned, that will not be delivered within 20 days of the sale. It is illegal for directors and executive officers (including each individual subject to reporting under Section 16 of the U.S. Exchange Act of the Company) to sell the Company’s securities short. “Derivative securities” are options, warrants, stock appreciation rights or similar rights whose value is derived from the value of an equity security, such as the Company’s Common Shares. This prohibition includes, but is not limited to, trading in Company-based option contracts, transacting in variable forward contracts, equity swaps, straddles or collars, hedging, and writing puts or calls. Nevertheless, holding and exercising options, deferred share units, performance share units, restricted stock units or other derivative securities granted under an equity-based compensation or incentive plan of the Company are not prohibited by the Company’s Insider Trading Policy.

The Board, acting on the recommendation of the Corporate Governance and Compensation Committee, has adopted a Board Shareholder Communication and Engagement Policy to promote open and sustained dialogue with the Company’s shareholders. The policy is consistent with the Company’s policies and its obligations to provide timely disclosure and maintain effective disclosure controls and procedures. A copy of our Board Shareholder Communication and Engagement Policy can be found on our website at www.dirtt.com/investors/leadership-and-governance.

As part of our commitment to ongoing shareholder communication and engagement, the Company communicates with our shareholders through a variety of channels, including quarterly and annual disclosure, earnings conference calls, presentations at investor and industry conferences, news releases and our website. Details of our quarterly conference calls and other investor-related information are posted at the Company’s website at www.dirtt.com/investors.

We encourage our shareholders to contact the Board to discuss our approach to executive pay, corporate performance and governance. All shareholder communications intended for the Board will be received and processed by the Company’s general counsel’s office, where they will be reviewed and forwarded to the Chair of the Board with a recommendation about whether and how to respond to the communications. The Chair of the Board will determine whether and how the communication should be addressed. Any engagement with shareholders will be subject to compliance with the Company’s communications policies and all applicable laws, including those regarding selective disclosure. Shareholders may address communications to Board members as follows:

Our current executive officers and their respective ages and positions as of the Record Date are set forth in the following table. Biographical information regarding each executive officer (other than Mr. Urban) is set forth following the table. Biographical information for Mr. Urban is set forth above under “Proposal No. 1—Election of Directors.”

Fareeha Khan became our Chief Financial Officer in August 2023 after four years with the Company. She started as Director, Internal Controls and served in that role from 2019 to 2022. Then she served as our Financial Controller and Vice President, Finance during 2023.

None of the Company’s executive officers have been involved in any legal proceedings requiring disclosure under U.S. federal securities laws.

As an “emerging growth company,” we are required to provide a Summary Compensation Table and an Outstanding Equity Awards at Fiscal Year End Table, as well as limited narrative disclosures regarding executive compensation for our last completed fiscal year. These reporting obligations extend only to our “named executive officers” or “NEOs,” who are the individuals who (i) served as our principal executive officer, (ii) our two other most highly compensated executive officers other than the principal executive officer, and (iii) up to two additional individuals for whom disclosure would have been required but for the fact that the individual was not serving as one of our executive officers during the last completed fiscal year. For the fiscal year ended December 31, 2023, our NEOs were:

The disclosure in this “Executive Compensation” section pertains to the compensation earned or paid to our NEOs for the fiscal year ended December 31, 2023.

The Company has implemented the following strong corporate governance practices:

We believe our executive officers should have a meaningful ownership stake in DIRTT to underscore the alignment of executive officer and shareholder interests and to encourage a long-term perspective. Accordingly, the Board has adopted share ownership and retention guidelines for our executive officers as follows:

Our executive officers are encouraged to retain 50% of the net Common Shares they acquire upon the vesting or exercise of any equity incentive awards they receive from us, after deducting the number of Common Shares that would be needed to pay applicable taxes and/or exercise price, until they meet the applicable share ownership guideline. The Corporate Governance and Compensation Committee reviews the status of compliance with the Executive Share Ownership Guidelines on the first trading day of each calendar year, using the greater of (i) the five-day weighted average closing price of Common Shares (on the exchange with the higher 20-day average trading volume) immediately prior to such date, and (ii) acquisition cost. Our NEOs are currently in compliance with the Executive Share Ownership Guidelines. As a result of the current stock price, the share ownership and retention guidelines have been suspended.

On February 25, 2020, the Board adopted the Clawback Policy to permit the Company to recover certain incentive compensation paid to our executives, including our NEOs, in the event of a restatement of the Company’s financial statements due to material non-compliance with any financial reporting requirements under applicable securities laws that the Board or a committee thereof determines is due in whole or in part to fraud or intentional misconduct by such executive(s). Pursuant to the Clawback Policy, the Company may recoup any cash, equity, or equity-based compensation received by our executives under any of the Company’s incentive plans. The Company is not currently subject to the requirements of Section 10D of the Exchange Act or Section 303A.14 of the NYSE Listing Company Manual nor was it subject to those requirements as of their effectiveness, and, as a result, the Clawback Policy is not intended to comply with those requirements. If the Company becomes subject to Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listing Company Manual in the future, the Clawback Policy will be amended to comply with the same.

The following table provides information regarding the compensation earned by our NEOs during the fiscal years ended December 31, 2023 and December 31, 2022, as applicable for the year that those individuals were deemed to be NEOs. All amounts in this table and the accompanying footnotes were paid in Canadian dollars, with the exception of Messrs. Urban and Little, who were paid in U.S. dollars. All amounts in this table and the accompanying footnotes that were originally paid in Canadian dollars have been converted to U.S. dollars for purposes of this table using the daily average exchange rate as reported by the H.10 statistical release of the Board of Governors of the Federal Reserve System on December 29, 2023 exchange rate of C$1.3202 = US$1.00. All amounts in this table and the accompanying footnotes pertaining to 2022 compensation paid in Canadian dollars have also been converted to U.S. dollars using the December 30, 2022 exchange rate of C$1.3532 = US$1.00. See “Narrative Disclosure to Summary Compensation Table—Base Salary” for more information regarding the Company’s use of a different exchange rate for payroll purposes only.

Amounts in this column represent the aggregate grant date fair value of the time-based and performance-based RSUs granted under our LTIP, calculated in accordance with FASB ASC Topic 718 using the trading price of the Common Shares as reported on the TSX on the grant date, disregarding estimated forfeitures. For a discussion of valuation assumptions, see Note 16 included under Stock-Based Compensation in our Consolidated Financial Statements for the year ended December 31, 2023 filed on Form 10-K. Messrs. Urban and Hunter were each granted 922,804 and Mr. Little was granted 738,553 PSUs under the LTIP. The market value of these awards at the grant date, assuming the highest level of performance conditions will be achieved, was $1,617,793 ($577,714 for Mr. Urban, $577,714 for Mr. Hunter and $462,365 for Mr. Little). These PSUs were assigned a fair value of zero at the time of the grants as the achievement of performance targets was not probable, as such, this is the value disclosed in the table above. All awards and amounts in this column and note for 2023 for Mr. Little were forfeited upon his resignation.

Base salary is used to recognize the experience, skills, knowledge and responsibilities required of our NEOs. In determining base salaries, the Board also takes into account each NEO’s knowledge of the industry and the financial resources of the Company. The Board believes that the base salaries of our NEOs are competitive to those that are received by comparable officers with comparable responsibilities in similar companies.

We provide short-term cash incentives to our NEOs through the VPP. The 2023 VPP was constructed so that an NEO's variable pay is tied to company-wide performance, placing the emphasis on company-wide results and team work. The annual variable pay potential for each NEO represents a meaningful amount of additional compensation to act as a strong incentive to achieve our financial goals, while being fiscally prudent. For 2023, opportunities under the VPP ranged from 0% to 100% of base salary actually paid during the calendar year.

Note that only Messrs. Urban and Hunter and Ms. Khan were eligible for the VPP. Mr. Little departed the Company during 2023 and was not eligible for any payment under the 2023 VPP.

The Board-approved metrics under the 2023 VPP were based on financial targets but also take into account individual and team performance. For eligible NEOs, the applicable financial measures were Revenue, and an internally calculated Adjusted Free Cashflow. Adjusted Free Cashflow is an internal measure calculated by taking GAAP cashflow from operations less capital expenditures and after adjusting for non-operational or on time cash impacts (for example, government subsidies, the 2023 transaction with Armstrong World Industries Inc., asset sales, and severance payments). As used herein, “Revenue” means the Company’s total revenue from all sources determined in accordance with U.S. GAAP, as reported in the Company’s publicly filed financial statements for the 2023 fiscal year.

Under the terms of the VPP, for participants to earn threshold, target, or maximum amounts under the financial targets, the following Company Revenue and Adjusted Free Cashflow performance levels had to be achieved:

If the actual results fell between the threshold and target performance goals or between the target and maximum performance goals, then the Compensation Committee may use judgment to determine the amount of the bonuses earned by participants under the VPP.

For 2023, we reported revenue of $181.9 million in our publicly-filed financial statements for the 2023 fiscal year which was above the target but less than the maximum performance level. The Adjusted Free Cashflow for 2023 was greater than $nil. The Board also assessed each NEO’s performance against their respective strategic/team objectives. Based on the significant changes in the Company during 2023 and successful management transitions, the Compensation Committee assessed achievement of the targets as 75%.

The Board assessed each NEO’s performance against their respective strategic/team objectives. Each NEO was eligible for a VPP payout of between 50% and 100% of the Company’s achieved percentage. The Board-approved VPP payout was as follows, which amounts are reported in the Non-equity Incentive Plan Compensation column of the Summary Compensation Table, above:

In addition to the short-term incentive plan, our NEOs are eligible to receive annual awards of long-term equity incentives under our LTIP. For 2023, target long-term incentive awards for our NEOs were as follows:

In prior years, NEOs have been awarded time-based and performance-based RSUs under our LTIP equal to approximately 145% of the value of their base salary. In 2023, the Compensation Committee revised the approach used. A one-time LTI grant of 150,000 time-based RSUs, vesting over a one-year period, was granted to all NEOs. 450,000 RSUs granted to Mr. Little in 2023 were forfeited on his departure in August 2023.

For Messrs. Urban, Hunter and Little, the Board approved an additional long-term incentive program comprising of PSUs with a performance period of January 1, 2023 to December 31, 2026 based on continued employment through that date and performance during that period, and will be settled shortly thereafter. The grant date of the PSUs was June 9, 2023 and was for a target number of 2,584,161 PSUs in aggregate, representing 2.5% of the issued and outstanding shares of the Company at the time. The PSUs were allocated 35.71% to each of Messrs. Urban and Hunter and 28.58% to Mr. Little. Under the terms of the agreement, the participants could earn up to a maximum of 190% of the target number of PSUs granted:

There will be no interpolation between the thresholds in determining settlement amounts.

As used herein, “Revenue” means the Company’s total revenue from all sources determined in accordance with U.S. GAAP, as reported in the Company’s publicly filed financial statements for the 2023 fiscal year. “EBITDA” shall mean net income before interest, taxes, depreciation and amortization.

This target was not achieved in the fiscal year 2023 and no PSUs have vested under the above program.

The following table sets out the key features of our LTIP . If approved at the Meeting, the A&R LTIP, which increases the aggregate number of Common Shares reserved and available for issuance under the LTIP by 15,000,000 will become effective on, May 9, 2024. See “Proposal No. 3 – Approval of the Company’s Second Amended and Restated Long Term Incentive Plan” for more information.

The Board has adopted the Company’s 2022 Employee Share Purchase Plan (“ESPP”) to encourage ownership of Common Shares and to align the interest of employees, including NEOs, more closely with those of shareholders. All employees, including the NEOs, are eligible to participate in the ESPP. Under the ESPP, employees are able to purchase Common Shares up to an aggregate amount of 10% of their base salaries at a price equal to 85% of the volume-weighted average trading price of the Common Shares as reflected on the TSX over the final five trading days of each offering period.

Certain of our NEOs receive limited perquisites and other benefits, the value of which is disclosed in the “All Other Compensation” column of the Summary Compensation Table in accordance with Item 402(n) of Regulation S-K but are deemed immaterial pursuant to Item 402(o)(7) of Regulation S-K and thus are not described below. Certain of our NEOs have entered into agreements or arrangements pursuant to which we have provided additional perquisites or benefits that are deemed material pursuant to Item 402(o)(7) of Regulation S-K and such benefits are described below.

We have entered into employment agreements with each of our NEOs (the “Employment Agreements”). Under these Employment Agreements, each of our NEOs is entitled to a certain level of base salary, minimum short-term incentives under the VPP, as well as certain severance benefits upon a qualifying termination of employment. The Employment Agreements include customary restrictive covenants, including those precluding the executives from soliciting employees or competing with us for a period of time following termination of employment.

On June 22, 2022, we entered into an executive employment agreement with Benjamin Urban (the “Urban Employment Agreement”). The Urban Employment Agreement provides Mr. Urban with (i) an annualized base salary of U.S. $375,000, (ii) eligibility to participate in the VPP with a target short-term incentive bonus opportunity as set by the Board; (iii) eligibility to participate in a 2022 Target Bonus; (iv) eligibility to participate in the LTIP, (v) reimbursement of tax preparation expense up to a maximum of $5,000 per year, (vi) reimbursement of relocation expenses up to a maximum of $15,000 plus an additional $2,500 payment, (vii) provision of director and officer insurance coverage or coverage under any other applicable insurance plans or policies for directors or officers of the Company, (viii) four weeks of vacation per calendar year, and (ix) eligibility to participate in our broad- based employee benefit plans, as may be adopted from time to time, subject to the eligibility requirements of such employee benefit plans.

For information regarding the payments that the Hunter Employment Agreement provides upon a termination of employment or a change of control, see “Additional Narrative Disclosure—Agreements with our NEOs—Hunter Employment Agreement.”

On August 17, 2022, we entered into an executive employment agreement with Mr. Little (the “Little Employment Agreement”). The Little Employment Agreement provided that Mr. Little was entitled to an annualized base salary of $300,000 and was eligible to participate in the VPP. The Little Employment Agreement also provided for a one-time signing bonus of $50,000 that was paid in 2022. The Little Employment Agreement further provided that Mr. Little was eligible to participate in the Company’s standard employee benefit plans and programs, including the Company’s ESPP. Mr. Little was eligible for four weeks of paid vacation per completed calendar year (pro-rated for partial calendar years), increased by one week for each five years of service up to a maximum of six weeks.

In connection with her appointment on August 2, 2023, Ms. Khan entered into an executive employment agreement with the Company, effective as of August 25, 2023 (the “Khan Employment Agreement”). Pursuant to the Khan Employment Agreement, Ms. Khan receives an annualized base salary of CAD $300,000 and was eligible to receive a target annual performance bonus under the VPP for 2023 equal to 50% to 100% of the base salary paid to her in 2023. Ms. Khan (i) will be paid a one-time cash bonus of CAD $50,000 (the “Cash Bonus”), paid one year after the effective date of the Khan Employment Agreement, and (ii) received a one-time award of 150,000 time-vested restricted share units under the LTIP, which shall vest one year after the date of grant. The Khan Employment Agreement further provides that Ms. Khan is eligible to participate in the Company’s standard employee benefit plans and programs, including the Company’s ESPP. Ms. Khan will also be eligible for five weeks of paid vacation per completed calendar year (pro-rated for partial calendar years), increased by one week for each five years of service up to a maximum of six weeks.

The number in this column represents 100% of the target number of PSUs granted on June 9, 2023 to Messrs. Urban and Hunter which will become earned over the three-year performance period ending on June 9, 2026, depending on the level of achievement of the applicable performance conditions and subject to Messrs. Urban and Hunter’s continued employment through such dates. In accordance with SEC rules, the number of PSUs reported in this column assumes the applicable performance metrics are achieved at the target level for the PSUs granted in 2023, which may not be representative of the actual payments that will occur upon the settlement of such awards, as such actual payouts may be significantly more or less.

The Employment Agreements generally provide for severance payments and benefits following certain terminations of employment in exchange for the NEOs’ compliance with certain customary restrictive covenants. Outstanding equity awards are governed by the terms of the LTIP and the individual award agreements governing each separate grant of awards.

Such payments will be conditioned upon Mr. Urban executing a general release in favor of the Company, and continued compliance with all restrictive covenants set forth within the employment agreement.

As used in the Khan Employment Agreement, the following terms generally have the following definitions:

In connection with Mr. Little’s resignation August 25, 2023, he received all accrued salary, vacation and reimbursement of expenses that existed at the time of his resignation. He executed a general release in our favor at the time of his termination, and he will continue to be subject to the restrictive covenants within his previous employment agreement for a period of 12 months following his termination date.

Each of the outstanding RSUs and PSUs that Mr. Little held at the time of his separation from service were forfeited.

The treatment of LTIP awards upon the death, disability, retirement or termination of employment of a participant are set out in the applicable award agreement. Under the award agreements for time-based RSUs, except in the event of a “Change of Control”, if the participant’s service, consulting relationship, or employment with the Company is terminated for any reason other than death, “Disability”, “Retirement”, by the Company without “Cause” or by the participant for “Good Reason” (each as defined below) prior to the last vesting date, the unvested RSUs will be forfeited and the participant will cease to have any right or entitlement to receive any payment (whether in cash or Common Shares or other property) under those forfeited units.

If the participant’s service, consulting relationship, or employment with the Company is terminated by reason of death or Disability, by the Company without Cause, or by the participant for Good Reason prior to the last vesting date, a pro-rata portion of the participant’s unvested RSUs shall vest immediately prior to the participant’s termination date based on the number of complete months from the date of grant to the termination date, divided by the total number of months in the period beginning on the date of grant and ending on the applicable vesting date.

If the participant’s service, consulting relationship, or employment with the Company is terminated by reason of Retirement prior to the last vesting date, the participant’s unvested RSUs shall remain outstanding and subject to the terms of the LTIP and the award agreement until the end of the applicable vesting date. The continued vesting of the participant’s RSUs is subject to the participant’s compliance with any post-employment restrictive covenants set out in the award agreement, including any non-competition restriction.

As used in the award agreement, the following terms generally have the following definitions:

•

“Good Reason” has the meaning used in the employment agreement between the NEO and the Company, if it is defined therein and, if not, it means: (a) without the express written consent of the participant, any material negative change or diminution of the participant’s authority, duties, reporting relationship, or responsibilities; (b) any material reduction in the participant’s base salary or hourly wage, as applicable, provided, however, that any reduction in base salary or hourly wage that applies to all similarly situated participants will not constitute “Good Reason” under the LTIP; (c) a change in the geographic location at which the participant must perform his or her services that is 50 miles or more from the principal location to which he or she was previously based as provided in his or her employment agreement, if any; or (d) any material breach by the Company of the participant’s employment agreement, if any, in each case, so long as the participant has provided the Company with written notice of the acts or omissions constituting grounds for Good Reason within 30 days of the condition first occurring and the Company shall have failed to rectify, as determined by the Company acting reasonably, any such acts or omissions within 30 days of the Company’s receipt of such notice.

The terms of the award agreements for performance based RSUs are generally the same as the above, provided that the pro rata vesting of the target number of performance based RSUs granted is based on the number of complete months from the first day of the performance period to the termination date, divided by the total number of months in the performance period and the award continues to be subject to the applicable performance criteria.

Under the terms of the LTIP, unless otherwise provided in the applicable award agreement, if, upon a Change of Control (as defined below), the successor entity does not assume outstanding awards or substitute similar awards on the same terms as the original awards, the vesting of all then outstanding awards will be accelerated in full with effect immediately prior to the Change of Control (vesting for performance-based Awards will be calculated based on target performance through the date of the transaction).

Under the terms of the LTIP, unless otherwise provided in the applicable award agreement, if, within 12 months following a Change of Control, a participant’s service, consulting relationship, or employment with the Company is terminated without Cause or the participant resigns from his or her employment with the Company for Good Reason (as those terms are defined in the A&R LTIP), the vesting and exercisability of all awards then held by such participant will be accelerated in full and the expiration date of the options and the share appreciate rights shall be the 60th day following the termination date.

A “Change of Control” means the occurrence of any of the following: (a) the acquisition by any person or any persons acting jointly or in concert, whether directly or indirectly, of voting securities of the Company which together with all other voting securities of the Company held by such persons, constitute, in the aggregate, 50% or more of the votes attached to all outstanding voting securities of the Company; (b) a merger, amalgamation, arrangement, or other form of business combination of the Company with another person which results in the holders of voting securities of that other person holding, in the aggregate, 50% or more of the votes attached to all outstanding voting securities of the Company; (c) the acquisition by any person or any persons acting jointly or in concert, whether directly or indirectly, of all or substantially all of the assets of the Company to another person during any 12 month period, other than in the ordinary course of business of the Company or to any person that controls or is controlled by the Company or that is controlled by the same person as the Company; or (d) a majority of the members of the Board are replaced during any 12 month period by directors whose appointment or election is not endorsed by a majority of the Board before the date of appointment or election.

Ms. Khan is the only current NEO that holds outstanding Options that were granted under the Company’s prior Option Plan, which was replaced by the LTIP. The Option Plan provides that if a participant ceases to be employed by us, other than by reason of death, “Disability” or “Retirement” (each as defined below), his or her stock options shall expire on the 60th day following such participant’s termination date, unless such participant was terminated for “Cause,” resigned without “Good Reason” or was ordered to resign by any “Regulatory Authority” having jurisdiction to do so (each as defined below).

In the event of a participant’s death, Disability or Retirement, his or her stock options will expire on the date that is six months following such participant’s termination date.

If the participant’s employment is terminated by us without Cause or by the participant for Good Reason, in each case, within 12 months of a “Change of Control” (as defined below), then all unvested stock options held by such participant shall immediately vest and the expiration date of such stock options shall be the 60th day following the participant’s termination date.

As used in the Option Plan, the following terms generally have the following definitions:

•

“Cause” means (i) fraud, misappropriation of our property or funds, embezzlement, malfeasance, misfeasance or nonfeasance in office, which is willfully or grossly negligent on the part of the participant, (ii) the willful allowance by the participant of allowing his or her personal interests to come into conflict in any material way with our interests, (iii) the breach by the participant of any non-competition, non-solicitation or confidentiality covenants in the participant’s employment agreement, or (iv) any other reason which would be concluded by a court of competent jurisdiction to amount to just cause at common law;

•

“Change of Control” means (i) the acquisition by any single person or company, directly or indirectly, of at least 50% of our voting power, (ii) a merger, amalgamation or arrangement of the Company with another company which results in the holders of the voting securities in that other company holding 50% or more of our voting power, (iii) the sale, lease or exchange of all or substantially all of our assets, other than in the ordinary course of business or to any single person or company that controls or is controlled by the same person or company as us, and (iv) the replacement of a majority of the members of the Board during any 12-month period by directors whose appointment is not endorsed by a majority of the current Board members;

•

“Good Reason” means, without the participant’s written consent, (i) a material change or diminution of the participant’s title, authority, status, duties, reporting relationship, or responsibilities, (ii) a material reduction in the participant’s salary, benefits, pension, variable and incentive compensation (including discretionary bonuses), perquisites and allowances, (iii) the requirement that the participant be based anywhere other than at the principal location to which he or she is based in his or her employment agreement, (iv) our breach of any material provision of the participant’s employment agreement, or (v) any other reason that would be concluded by a court of competent jurisdiction to amount to a constructive dismissal at common law;

Non-executive directors are compensated by an annual retainer, generally payable in equity-based awards. Up to May 30, 2023, the equity component was in the form of DSUs under our DSU Plan. Upon departure of a Director, the DSUs were settled in cash using the market price of the Company’s Common Shares determined in accordance with the DSU Plan. DSUs granted prior to the adoption of the LTIP are governed by the terms of the DSU Plan and will be settled in cash. DSUs awarded after May 30, 2023 will be settled on the departure of a Director at the option of the Company in shares or cash to the such Director, using the valuation terms described in the LTIP.

The retainers payable to members of the Board and each committee of the Board are as follows:

We also reimburse the directors for out-of-pocket expenses for attending meetings.

Directors do not receive fees for attending meetings of the Board or standing committees; however, directors may be compensated for additional committee work as approved by the Board from time to time, including as members of the Special Committee as outlined above. Mr. Urban did not receive any additional compensation for his service as a director, and all compensation that he received for the 2023 year are reflected above within the Summary Compensation Table. During 2023, the Chair of the Board, Mr. Sanders, received cash compensation of $50,000 as additional compensation for his service as a consultant for the year.

As discussed in other sections of this document, DSUs were previously granted under the DSU Plan. Following the adoption of the LTIP on May 30, 2023, no new awards were granted under the DSU Plan, but awards previously granted under the DSU Plan have continued to be governed by the DSU Plan and have continued to be credited Dividend Equivalent Rights under the DSU Plan. All share-based awards following the adoption of the LTIP, whether granted to employees, officers, consultants or directors, will be granted under the LTIP.

DSUs are notional units which have the same value as the Common Shares. Under the DSU Plan, non-employee directors will be credited 100% of their annual retainer in DSUs quarterly. Prior to the delisting of our Common Shares from Nasdaq, the number of DSUs granted quarterly were determined using the five-day weighted average trading price of the Common Shares immediately prior to each grant date, on the TSX.

The DSU Plan provides that upon a non-employee director’s resignation, death, or retirement from the Board, such non-employee director shall receive a cash payment equal to the five-day weighted average trading price of the Common Shares underlying the DSUs held by such non-employee director, determined as of the date of such non-employee director’s resignation, death, or retirement from the Board, on the TSX.

Pursuant to the terms of our Director Share Ownership Guidelines, approved on November 3, 2015 and amended on October 3, 2019, within five years of the later of appointment or adoption of the guidelines, each of our non-employee directors is required to hold a number of Common Shares equivalent in value to three times his or her annual base retainer. Common Shares that may be counted towards a director’s ownership include (i) Common Shares purchased on the open market or received through share-based grants from the Company, (ii) Common Shares indirectly owned by the director, including shares held by a spouse or other immediate family member, (iii) Common Shares held in trust for the benefit of the director, his or her spouse or children or direct descendants, (iv) Common Shares underlying stock options, whether or not vested, and (v) DSUs awarded under the DSU Plan, with each unit counting as one Common Share. As of December 31, 2023 all directors are in compliance with the Director Share Ownership Guidelines or are within their allowed transition period.

The following table sets forth a summary of the compensation we paid to our non-employee directors for 2023.

(2)

Amounts in this column include the value of annual retainers, meeting fees, and additional compensation for Special Committee work undertaken by directors and approved by the Board, as applicable.[1]Amounts in this column for all non-employee directors represent the aggregate grant date fair value of the DSUs granted to non-employee directors in 2023, calculated in accordance with FASB ASC Topic 718. The FASB ASC Topic 718 value for the DSUs issued prior to May 30, 2023 was calculated using the five-day volume-weighted average trading price of the Common Shares as reported on the TSX on the grant date applied to the total number of DSUs granted. With the adoption of the LTIP, DSUs issued subsequent to May 30, 2023 were valued using the closing price of Common Shares as reported on the TSX or Nasdaq, whichever exchange had the higher average trading volume for the 20 days immediately prior, (or, subsequent to the Company’s delisting from Nasdaq, the TSX) on the day immediately preceding the specified date. The aggregate additional information regarding the assumptions underlying these calculations is available in Note 16 to our consolidated financial statements filed with our Form 10-K for the fiscal year ended December 31, 2023. There are no outstanding unvested DSUs as such awards are fully vested upon grant, but as of December 31, 2023, the following number of DSUs were held by each of our directors: Mr. Edwards, 515,195; Mr. English, 427,315; Mr. Noll, 439,259; Mr. Robinson, 567,448; Mr. Ryan, 559,263; and Mr. Sanders, 577,691.

Other than the director and executive compensation arrangements discussed above in “Executive Compensation” and “Director Compensation,” and as set out below, there have not been any transactions since January 1, 2022, to which we have been or will be a participant, in which the amount involved exceeded or will exceed $120,000, and in which any of our directors, executive officers or holders of more than 5% of any class of our voting shares, or any member of the immediate family of, or person sharing the household with, any of these individuals, had or will have a direct or indirect material interest.

On November 30, 2022, the Company closed a private placement of 8,667,449 Common Shares at a subscription price of $0.32 (the “Subscription Price”) for aggregate gross consideration of $2.8 million (the “Private Placement”) with its two largest shareholders, 22 NW Fund and 726 BC LLC and 726 BF LLC (together “726”) and all of the Company’s directors and officers at the time, including 638,996 Common Shares issued at a deemed per share price equal to the Subscription Price, as reimbursement for the costs incurred by 726 in connection with the Company’s contested director elections in 2022.

On March 15, 2023, the Company entered into the Debt Settlement Agreement with 22NW. Pursuant to the Debt Settlement Agreement, the Company agreed to reimburse 22NW for the Debt related to the 2022 Meeting, being $1,559,898, 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 the Share Issuance 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 $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 the year, C$18.9 million and C$13.6 million of our 6.00% convertible unsecured subordinated debentures due January 31, 2026 (the “January Debentures”) and our 6.25% convertible unsecured subordinated debentures due December 31, 2026 (together with the January Debentures, the “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 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, Shaun Noll and 726 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.

The Company entered into a binding term sheet, dated March 17, 2024, with 22NW Fund, which provided for the entry into a subsequent definitive Support and Standstill Agreement (the “Support Agreement”), which Support Agreement was entered into on March 22, 2024 with 22NW Fund. Pursuant to the Support Agreement, subject to 22NW Fund continuing to beneficially own, or exercising control or direction over, at least the lesser of (i) not less than 20% of the then issued and outstanding Common Shares and (ii) 38,222,077 Common

Shares (subject in each case to adjustment for stock splits, reclassifications, combinations and similar adjustments), the Company has agreed to nominate Aron English (or a replacement director to be identified by 22NW Fund) (the “Shareholder Director”) for election as a director at each of the 2024 Meeting and 2025 Meeting.

Until the day following the 2025 Meeting, 22NW Fund has agreed to vote all of their Common Shares in favor of recommendations of the Board on director election proposals, subject to certain exceptions. In addition, until the day following the 2025 Meeting, 22NW has agreed, subject to certain exceptions, to comply with certain customary standstill provisions, including, among other things, that 22NW Fund will not (i) make, participate in or encourage any solicitation of proxies or consents; (ii) seek to requisition, join in any requisition or call a meeting of shareholders of the Company in respect of the election of directors of the Company; (iii) submit or induce any party to submit any shareholder proposal in respect of the Company; (iv) advise, assist, encourage or act jointly or in concert with any party in connection with any of the foregoing; or (v) make any public disclosure of any consideration, intention, plan or arrangement inconsistent with any of the foregoing.

22NW will also agree to vote in favor of the shareholder rights plan (the “Rights Agreement”), which was adopted on March 22, 2024 by the Board. Provided that the Rights Agreement is approved by the Company’s shareholders, until the termination of the Support Agreement, 22NW will not commence an unsolicited Take-over Bid (as such term is defined in the Rights Agreement) for the Common Shares.

The Support Agreement will terminate upon the earlier of: (i) 30 days prior to the last date that a nomination for election as a director of the Company at the Company’s 2026 annual meeting of shareholders can be made in accordance with Section 6.02 of the Company’s Amended and Restated By-Laws and (ii) 60 days prior to the one-year anniversary of the 2025 Meeting.

The Company has adopted a written Related Party Transactions Policy, which provides that our Corporate Governance and Compensation Committee is responsible for reviewing “related party transactions,” which are transactions, arrangements or relationships (or any series of similar transactions, arrangements or relationships), to which we are a party, in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has, had or will have a direct or indirect material interest. For purposes of this policy, a “related person” is defined to include a director, executive officer, nominee for director and greater than 5% beneficial owner of our voting securities, in each case since the beginning of the most recently completed year, and any of their immediate family members. In determining whether to approve or ratify any such transaction, the Corporate Governance and Compensation Committee will take into account, among other factors it deems appropriate, (i) whether the transaction is on terms comparable to the terms generally available to unaffiliated third parties under the same or similar circumstances and (ii) the extent of the related party’s interest in the transaction.

All of the transactions described above in “Transactions with Related Parties” were approved in accordance with the foregoing policies and procedures, other than the purchase of the Debentures owned by the 22NW Group, as such transactions were solely between the 22NW Group and third parties, there was no involvement in the transactions by the Company.

Other than as disclosed under “Certain Relationships and Related-Party Transactions”, management is not aware of any material interest, direct or indirect, of any informed person of the Company, any proposed director or any associate or affiliate of any informed person or proposed director 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.

As of the date of this Proxy Statement, no current or proposed director, executive officer, other corporate officer or employee of the Company, or any former director, executive officer, other corporate officer or employee of the Company, or any associate of any of the foregoing, is, or has been at any time during 2023, indebted to the Company or its subsidiaries, either in connection with the purchase of securities of the Company or otherwise.

The following table includes information, as of March 20, 2024, about the beneficial ownership of our Common Shares for:

Beneficial ownership is determined in accordance with SEC rules. The information contained in the following table is not necessarily indicative of beneficial ownership for any other purpose, and the inclusion of any shares in the table does not constitute an admission of beneficial ownership of those shares. Except as otherwise indicated by footnote, the number of shares and percentage ownership indicated in the following table is based on 191,456,899 outstanding Common Shares as of March 20, 2024. Our Common Shares subject to stock options or other derivative instruments that are currently exercisable or exercisable within 60 days of March 20, 2024 are deemed to be outstanding and to be beneficially owned by the entity or person holding such stock options or other derivative instrument for the purpose of computing the percentage ownership of such entity or person but are not treated as outstanding for the purpose of computing the number of shares owned and percentage ownership of any other entity or person.

Unless otherwise indicated by footnote and subject to community property laws where applicable, to our knowledge, the persons named in the following table will have sole voting and investment power with respect to all Common Shares shown as beneficially owned by them, except to the extent authority is shared by spouses under community property laws.

The following report of the Audit Committee of the Board does not constitute soliciting material and should not be deemed filed or incorporated by reference into any future filings under the U.S. Securities Act of 1933 or the Exchange Act, except to the extent we specifically incorporate this report by reference.

Management has the primary responsibility for establishing and maintaining adequate internal financial controls, for preparing the financial statements and for the public reporting process. PwC, the Company’s independent registered public accounting firm, is responsible for expressing opinions on the conformity of the Company’s audited financial statements with U.S. generally accepted accounting principles.

The Audit Committee has reviewed and discussed with management and PwC the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2023. The Audit Committee has also discussed with PwC the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the “PCAOB”) and the SEC.

The Audit Committee also received the written disclosures and the letter from PwC that are required by applicable requirements of the PCAOB regarding PwC’s communications with the Audit Committee concerning independence and has discussed with PwC its independence. On the basis of the foregoing, the Audit Committee concluded that PwC is independent from the Company, its affiliates and management.

Based upon its review of the Company’s audited financial statements and the discussions noted above, the Audit Committee recommended to the Board that the Company’s audited consolidated financial statements for the fiscal year ended December 31, 2023 be included in the Company’s Annual Report on Form 10-K for such fiscal year, which was filed with the SEC.

Under Section 16(a) of the Exchange Act and SEC rules, our directors, executive officers and beneficial owners of more than 10% of any class of equity security are required to file periodic reports of their ownership and changes in that ownership with the SEC. Based on our review of the filed reports, because of an administrative oversight of the Company, we believe that [nine] Form 4s were filed late. Seven of these late filings, filed by Aron English, Scott Ryan, Shaun Noll, Kenneth Sanders, Douglas Edwards, Cory Mitchell and Scott Robinson, respectively, were due to delays in assessing the impact of the new DSU program that came into effect May 30, 2023, and, in each case, the grant of the June 30, 2023 DSUs were therefore filed late. The other two late filings were by Shaun Noll in the third quarter of 2023 relating to the purchase of common shares on September 18, 2023 (filed on September 22, 2023) and one in the fourth quarter of 2023 relating to the purchase of rights on December 20, 2023 filed on December 26, 2023.

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 the management information circular and proxy statement, 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 the 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 20, 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 the 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:

We file or furnish annual, quarterly and current reports, proxy statements and other documents with the SEC under the Exchange Act. The SEC maintains a website at www.sec.gov that contains reports, proxy and information statements, and other information regarding issuers, including DIRTT, that file electronically with the SEC. We are also subject to requirements of the applicable securities laws of Canada, and documents that we file with the Canadian Securities Administrators may be found at www.sedarplus.ca.

Our 2023 annual report to shareholders, including our Annual Report on Form 10-K for the year ended December 31, 2023, is being made available to shareholders concurrently with this Proxy Statement.

At any time that a member of the Committee is not a Qualified Member, any action of the Committee relating to an Award granted or to be granted to an insider where such action is not taken by the full Board may be taken either (i) by a subcommittee, designated by the Committee, composed solely of two or more Qualified Members, or (ii) by the Committee but with each such member who is not a Qualified Member abstaining or recusing himself or herself from such action; provided, however, that upon such abstention or recusal, the Committee remains composed solely of two or more Qualified Members. Such action, authorized by such a subcommittee or by the Committee upon the abstention or recusal of such non-Qualified Member(s), shall be the action of the Committee for purposes of the Plan. For the avoidance of doubt, the full Board may take any action relating to an Award granted or to be granted to a Participant who is an insider.

The Committee and each member thereof shall be entitled to, in good faith, rely or act upon any report or other information furnished to him or her by any officer or Employee of the Corporation or any Affiliate, the Corporation’s legal counsel, independent auditors, consultants or any other agents assisting in the administration of the Plan. Members of the Corporation and any officer or Employee of the Corporation or any Affiliate acting at the direction or on behalf of the Committee shall not be personally liable for any action or determination taken or made in good faith with respect to the Plan, and shall, to the fullest extent permitted by law, be indemnified and held harmless by the Corporation with respect to any such action or determination.

iv.

Sources of Shares Deliverable under Awards. Where the Corporation and Employer elect to distribute Shares pursuant to the exercise, vesting, or settlement of an Award, such Shares may consist, in whole or in part, of authorized and unissued Shares, or, except in respect of Options granted to Canadian Participants, Shares purchased on the open market. For greater certainty, except where an Award is explicitly stated to be required to be settled in Shares or as specifically provided in the applicable Award Agreement, (A) no Participant shall have any right to demand, be paid in, or receive Shares in respect of any Award; and (B) notwithstanding any election by the Corporation or Employer to settle any Award, or portion thereof, in the form of Shares, the Corporation and Employer reserves the right to change its election in respect thereof at any time until payment is actually made.

the aggregate number of Shares issuable pursuant to outstanding Awards under the Plan to directors of the Corporation who are not officers or Employees of the Corporation shall be limited to one percent (1%) of the total issued and outstanding Shares provided that the value of all Options issuable to any one (1) director who is not an officer or Employee of the Corporation within any one (1) year period shall not exceed one hundred thousand dollars ($100,000) and that the value of all Awards issuable to any one (1) director who is not an officer or Employee of the Corporation within any one (1) year period shall not exceed one hundred fifty thousand dollars ($150,000), not including Awards issued or taken in lieu of cash fees or a one-time initial grant to a new director upon joining the Board.

ii.

Notwithstanding any provision of the Plan to the contrary, the Committee shall not grant Awards to Participants with a vesting schedule that provides for full or partial vesting less than one year after the date of grant; provided, however, that (A) the Committee may grant Awards to Participants with a vesting schedule that provides for full or partial vesting less than one year after the date of grant so long as such Awards do not constitute more than five percent (5%) of the number of Shares available for issuance under the Plan, (B) Awards may vest upon death, termination of employment, or a Change of Control, and (C) this Section 4(b)(ii) shall not apply to Awards described in Sections 4(c) or 7(d)(i) of the Plan.

Shares Available Following Certain Transactions. Subject to Exchange requirements, including Exchange approval, as applicable, Awards granted pursuant to Section 8(f) of the Plan in substitution or exchange for awards previously granted by a company acquired by the Corporation or any subsidiary or with which the Corporation or any subsidiary combines shall not reduce the Shares authorized for issuance under the Plan, nor shall Shares subject to such Awards be added to the Shares available for issuance under the Plan pursuant to Section 4(a)(ii) of the Plan (whether or not such Awards are later cancelled, forfeited, or otherwise terminated).

Unless otherwise provided in the applicable Award Agreement, if, within twelve (12) months following the Change of Control, a Participant’s service, consulting relationship, or employment with the Corporation, an Affiliate, or the successor entity is terminated without Cause or the Participant resigns from his or her employment with the Corporation, an Affiliate, or the successor entity for Good Reason, the vesting and exercisability of all Awards then held by such Participant will be accelerated in full and the expiration date of the Options and the SARs shall be the earlier of the date such Awards would otherwise expire and the sixtieth (60th) day following the Participant’s Termination Date.

provided that, in respect of all Awards subject to Performance Criteria, for the purpose of the calculation of the Performance Criteria, as set forth in the particular Award Agreement, and determining the number of such Awards that shall vest in accordance with this Section 5(c), notwithstanding the terms of the Award Agreement, the Performance Criteria shall be measured and calculated assuming target performance was achieved.

Any Employee or consultant of the Corporation or an Affiliate or any provider of services to the Corporation or an Affiliate shall be eligible to be designated a Participant; provided that Deferred Share Units may be granted only to Eligible Directors. To the extent required by the Exchange(s), a consultant that is a Canadian Resident must provide services to the Corporation or an Affiliate for an initial, renewable, or extended period of twelve (12) months or more to be eligible to receive an Award. Notwithstanding anything else to the contrary in this Section 6 or any other section of the Plan, any individual that receives an Award that may be settled in Shares must be an “employee” of the Corporation or any of its parents or subsidiaries within the meaning of General Instruction A.1(a) to Form S-8.

ii.

Time and Method of Exercise. Subject to the terms of Section 8 hereof, the Committee will determine the vesting conditions, the time or times at which an Option may be exercised in whole or in part (provided that the Committee may determine that an Option may not be exercised in whole or part for a specified period after it is granted), and the method or methods by which, and the form or forms in which payment of the Exercise Price with respect thereto may be made. The Committee may decide to accept any of the following forms of payment for the Exercise Price: cash or cash equivalents, Shares (including previously owned Shares or through a cashless exercise, i.e., “net settlement”, a broker-assisted exercise, or other reduction of the amount of Shares otherwise issuable pursuant to the Option, provided that, in the case of a Canadian Participant, the Shares cannot be Shares acquired pursuant to the exercise of an Option in the preceding twenty-four (24) months), other Awards or awards granted under other plans of the Corporation or any Affiliate, other property, or any other legal consideration the Committee deems appropriate. In the case of an exercise whereby the Exercise Price is paid with Shares, such Shares shall be valued based on the Shares’ Fair Market Value as of the date of exercise. No Option may have a term of more than ten (10) years, and all Options granted to Canadian Participants shall be exercisable only for the issuance by the Corporation of authorized and previously unissued Shares from treasury (unless the Canadian Participant is entitled to elect payment in an alternative form, as set out in the applicable Award Agreement). Vesting of Options may be based upon the duration of service to the Corporation or any Affiliate, Performance Criteria, individual performance or other specific criteria, in each case on a specified date or dates or over any period or periods, as determined by the Committee.

ii.

Future Services Only. Notwithstanding any provision of the Plan or in an Award Agreement, a SAR granted to a Canadian Participant shall be granted solely in respect of the services of such Participant to be rendered to the Corporation and its Affiliates subsequent to the date of grant of the SAR and none of the main purposes of such grant may to be provide the Canadian Participant with a payment that is in lieu of salary or wages for services rendered by such Participant in the year in a previous calendar year. For greater certainty, no SAR granted to a Canadian Participant shall have any value prior to becoming vested and exercisable.

iii.

Time and Method of Exercise and Settlement. Subject to the terms of Section 8 hereof, the Committee will determine the vesting conditions, the time or times at which a SAR may be exercised in whole or in part (provided that the Committee may determine that a SAR may not be exercised in whole or part for a specified period after it is granted); provided, that no SAR may have a term of more than ten (10) years and further provided that any SAR granted to a Canadian Participant shall have a term extending not later than December 15thof the calendar year in which such SAR becomes vested and exercisable. Such vesting may be based upon the duration of service to the Corporation or any Affiliate, Performance Criteria, individual performance or other specific criteria, in each case on a specified date or dates or over any period or periods, as determined by the Committee. Upon exercise of a SAR, the Employer shall make to the Participant a payment equal to the excess of (A) the Fair Market Value of one Share on the date of exercise over (B) the grant price of the SAR, which payment shall, after deduction of any applicable taxes and other source deductions required to be withheld by the Employer, be paid in cash. At the Employer’s discretion, the Employer may elect to settle the cash payment obligation in respect of a SAR in the form of Shares (or in a combination of cash and Shares), in which case the Employer shall cause the Corporation to deliver such Shares directly to the Participant.

iv.

Rights Related to Options. A SAR granted in connection with an Option shall entitle a Participant, in lieu of exercising the vested Option, to surrender that Option or any portion thereof, to the extent unexercised, and to receive payment of an amount determined by multiplying (A) the difference obtained by subtracting the Exercise Price with respect to a Share specified in the related Option from the Fair Market Value of a Share on the date of exercise of the SAR, by (B) the number of Shares as to which that SAR has been exercised and the underlying Option surrendered. The Option shall then cease to be exercisable to the extent surrendered. SARs granted in connection with an Option shall be subject to the terms and conditions of the Award Agreement governing the Option, which shall provide that the SAR is exercisable only at such time or times and only to the extent that the related Option is exercisable and shall not be transferable except to the extent that the related Option is transferrable.

Vesting. Subject to the terms of Section 8 hereof, the Committee will determine the vesting conditions. The Committee may impose any conditions or restrictions on the vesting or payout of Restricted Share Units as it may deem appropriate, including, without limitation, vesting based upon the Participant’s duration of service to the Corporation or any Affiliate, Performance Criteria, individual performance or other specific criteria, in each case on a specified date or dates or over any period or periods, as determined by the Committee; provided, that no such condition or restriction shall cause any Restricted Share Unit that is granted to a Canadian Participant to fail to or cease to comply with the requirements of paragraph (k) of the exception to the definition of “salary deferral arrangement” in subsection 248(1) of the Tax Act.

Unless otherwise determined by the Committee in its sole discretion and set out in the applicable Award Agreement but subject to the requirements of Section 9(o) of the Plan, each Restricted Share Unit shall include a Dividend-Equivalent Right such that on the payment date for cash dividends paid on Shares (the “Dividend Payment Date”), each Participant’s Restricted Share Unit Account shall be credited with additional Restricted Share Units in respect of Restricted Share Units credited to and outstanding in the Participant’s Restricted Share Unit Account as of the record date for payment of such dividends (the “Dividend Record Date”). The number of such additional Restricted Share Units to be credited to the Participant’s Restricted Share Unit Account will be calculated (to two (2) decimal places) by dividing the total amount of the dividends that would have been paid to such Participant if the Restricted Share Units in the Participant’s Restricted Share Unit Account (including fractions thereof), as of the Dividend Record Date, were Shares, by the Fair Market Value of a Share on the Dividend Payment Date. The terms and conditions of any such additional Restricted Share Units shall be identical to the underlying Restricted Share Units held by such Participant. For the avoidance of doubt, no additional Restricted Share Units will be credited or granted pursuant to this Section 7(c)(ii)(B) where the Dividend Record Date relating to dividends falls after the termination of the Participant’s employment with or the cessation of services to the Corporation and its Affiliates, as applicable, or the settlement of such Restricted Share Units, whichever occurs first.

iv.

Payout of Restricted Share Units. On a date to be determined by the Committee, in its sole discretion, following the day on which any Restricted Share Units become Vested Restricted Share Units, which date, notwithstanding anything else contained in this Plan, shall in respect of all Restricted Share Units granted to Canadian Participants be on or before that date which is three (3) years following the end of the relevant RSU Service Year (the “Restricted Share Unit Entitlement Date”), such Vested Restricted Share Units shall be paid by the Participant’s Employer to the Participant or the Participant’s Beneficiary, as applicable. The Fair Market Value of the Vested Restricted Share Units so paid at such time shall, after deduction of any applicable taxes and other source deductions required to be withheld by the Employer, be paid in cash. At the Employer’s discretion, the Employer may elect to settle the cash payment obligation in respect of a Restricted Share Unit in the form of Shares (or in a combination of cash and Shares), in which case the Employer shall cause the Corporation to deliver such Shares directly to the Participant.

Mandatory Deferred Retainer Amount. The Board shall pass a resolution prior to December 31 of a year immediately preceding the particular year in which an Annual Retainer is earned and becomes payable determining: (i) whether any committee fees and per diem meeting fees shall be included as part of the Annual Retainer, and (ii) the percentage of the Annual Retainer otherwise payable to Eligible Directors that is required to be satisfied in the form of Deferred Share Units (the “Mandatory Deferred Retainer Amount”). In the absence of any such resolution, for calendar years commencing on or after January 1, 2023, the Annual Retainer shall include all committee fees and per diem meeting fees and the Mandatory Deferred Retainer Amount shall equal one hundred percent (100%) of the Annual Retainer.

Elective Cash Retainer Amount. Each Eligible Director shall have the right, but not the obligation, to elect, irrevocably and in advance, to receive all or a portion of such director's Annual Retainer that is in excess of the director's Mandatory Deferred Retainer Amount (the “Cash Retainer Amount”), if any, for the immediately succeeding year in the form of Deferred Share Units (the portion of the Cash Retainer Amount that an Eligible Director validly elects to defer in accordance with this Section 7(d)(i)(B), if any, the “Elected Deferred Retainer Amount”). Where the Cash Retainer Amount is greater than nil, any such election shall be made by completing, signing and delivering to the Secretary of the Corporation a Deferred Share Unit Election Form:

In each case, the election, when made, shall be irrevocable and will continue in effect thereafter until and unless a new election is made in accordance with this Section 7(d)(i)(B) and shall only apply prospectively with respect to the Eligible Director's Cash Retainer Amount yet to be earned.

Notwithstanding any other provision of this Section 7(d), if a Blackout Period is in effect, an Eligible Director may not deliver an election until the first day immediately following the expiration of the Blackout Period. If such date extends beyond December 31st of the calendar year, then no such election may be made in respect of the succeeding year and any election made in respect of previous years continues in effect until and unless a new election is made in accordance with this Section 7(d)(i)(B) for the next succeeding year.

Notwithstanding the making of any election, the Board, in its discretion, may determine that it is not feasible or desirable to honour an election in favour of Deferred Share Units due to any applicable laws of regulations of a regulatory authority, provided that such determination shall be made in accordance with Section 409A for all U.S. Eligible Directors.

Award of Deferred Share Units. The number of Deferred Share Units (including fractional Deferred Share Units) to be granted under this Section 7(d)(i) as of each Deferred Share Unit Award Date shall be determined by dividing (i) the Mandatory Deferred Retainer Amount and the Elected Deferred Retainer Amount, if any, (collectively, the “Deferred Retainer Amount”) earned since the immediately preceding Deferred Share Unit Award Date, or if the Eligible Director joined the Board since the preceding Deferred Share Unit Award Date, the date of the Eligible Director’s commencement of service on the Board by (ii) the Fair Market Value as of the Deferred Share Unit Award Date, rounded down to the nearest Deferred Share Unit.

ii.

Discretionary Deferred Share Units.The Board may, in its discretion, award Deferred Share Units to Eligible Directors in addition to Deferred Share Units awarded pursuant to the Mandatory Deferred Retainer Amount and Cash Retainer Amount, if any, on such terms and conditions as it determines, including as to vesting. The Board may impose any conditions or restrictions on the vesting or payout of Deferred Share Units as it may deem appropriate, including, without limitation, vesting based upon the Participant’s duration of service to the Corporation or any Affiliate, Performance Criteria, individual performance or other specific criteria, in each case on a specified date or dates or over any period or periods, as determined by the Board; provided, that no

Unless otherwise determined by the Board in its sole discretion and set out in the applicable Award Agreement but subject to the requirements of Section 9(o) of the Plan, each Deferred Share Unit shall include a Dividend-Equivalent Right such that on the Dividend Payment Date, each Eligible Director's Deferred Share Unit Account shall be credited with additional Deferred Share Units in respect of Deferred Share Units credited to and outstanding in the Eligible Director's Deferred Share Unit Account as of the Dividend Record Date. The number of such additional Deferred Share Units to be credited to the Eligible Director's Deferred Restricted Share Unit Account will be calculated (rounded down to the nearest Deferred Share Unit) by dividing the total amount of the dividends that would have been paid to such Eligible Director if the Deferred Share Units in the Eligible Director's Deferred Share Unit Account (including fractions thereof), as of the Dividend Record Date, were Shares, by the Fair Market Value (as determined for the purposes of Deferred Share Units) of a Share on the Dividend Payment Date. The terms and conditions of any such additional Deferred Share Units shall be identical to the underlying Deferred Share Units held by such Eligible Director.

The Corporation shall settle all Deferred Share Units credited to an Eligible Director's Deferred Share Unit Account on the Eligible Director's Deferred Share Unit Redemption Date for an amount of cash (the “Deferred Share Unit Amount”) equal to: (i) the number of Deferred Share Units credited and outstanding in the Eligible Director's Deferred Share Unit Account on the Deferred Share Unit Redemption Date multiplied by (ii) the Fair Market Value as at the Deferred Share Unit Redemption Date minus (iii) Applicable Withholding Taxes. The Deferred Share Unit Amount shall be paid as a lump-sum by the Corporation within ten days of the Deferred Share Unit Redemption Date, but, for greater certainty and without extending the ten day period described in the foregoing, in no event shall such amount be paid later than December 31 of the year following the year in which the Eligible Director's Termination Event or Separation from Service, as applicable, occurs. At the Corporation's discretion, the Corporation may elect to settle the cash payment obligation in respect of the Deferred Share Unit Amount in the form of Shares (or in a combination of cash and Shares), in which case the Corporation shall deliver one Share (less reductions for Applicable Withholding Taxes) for each Deferred Share Unit settled in Shares directly to the Eligible Director at the time specified above for cash settlement. Upon settlement of the Deferred Share Unit Amount, the Deferred Share Units shall automatically be cancelled and such Eligible Director shall have no further rights in respect of any Deferred Share Units under the Plan.

Eligibility for Deferred Share Units. Subject to the provisions of this Section 7(d), only Eligible Directors shall be entitled to be granted Deferred Share Units. If an Eligible Director becomes an Employee (other than by virtue of director status) of the Corporation or any Affiliate, such director's eligibility to receive grants of Deferred Share Units will be suspended for the period during which such director remains an Employee (other than by virtue of director status) of the Corporation or any Affiliate. In such a circumstance, the director shall not be eligible to be credited with additional Deferred Share Units (other than Deferred Share Units credited under Section 7(d)(iii)(B)) and shall not be eligible for redemption of Deferred Share Units until the date of the director's Termination Event or Separation from Service, as applicable.

The foregoing provisions of Section 7(d)(vi) are intended to avoid adverse tax consequences under Section 409A and under paragraph 6801(d) of the regulations under the Tax Act that may result because of the different requirements as to the time of redemption of Deferred Share Units (and thus the time of taxation) with respect to a U.S. Eligible Director’s Separation from Service (under U.S. tax law) and the Eligible Director’s Termination Event (under Canadian tax law). Unless it is determined that no adverse tax consequences under either the U.S. income tax regime or the Canadian income tax regime would result, such U.S. Eligible Director's Deferred Share Units shall be immediately and irrevocably forfeited (for greater certainty, without any compensation therefor) if either (i) such U.S. Eligible Director’s Separation from Service does not constitute a retirement from, or loss of, office or employment with, the Corporation or an Affiliate, within the meaning of paragraph 6801(d) of the regulations under the Tax Act; (ii) on such U.S. Eligible Director’s Termination Date, such U.S. Eligible Director has not had a Separation of Service; or (iii) any of the circumstances described in Sections 7(d)(vi)(i.) – (ii.) are applicable.

vii.

Tax Characterization. The Deferred Share Units granted hereunder are intended to satisfy the requirements of Section 409A and shall be operated and interpreted consistent with that intent for all U.S. Eligible Directors. Notwithstanding the foregoing, the Corporation makes no representations that the Plan or the Deferred Share Units complies with Section 409A, and shall have no liability to any Eligible Director for any failure to comply with Section 409A. The Deferred Shares Units granted hereunder are intended not to constitute a “salary deferral arrangement” within the meaning of subsection 248(1) of the Tax Act on the basis that they satisfy the requirements of paragraph (l) of such definition and paragraph 6801(d) of the regulations under the Tax Act, and this section 7(d) shall be interpreted and administered consistent with such intent. Notwithstanding the foregoing, the Corporation makes no representations that the Deferred Share Units comply with the requirements of paragraph (l) of the definition of “salary deferral arrangement” and paragraph 6801(d) of the regulations under the Tax Act, and shall have no liability to any Eligible Director for any failure to comply with the requirements of paragraph (l) of such definition and paragraph 6801(d) of the regulations under the Tax Act.

ii.

Rights of Restricted Share Holder. Subject to the requirements of Section 9(o) of the Plan and except as otherwise provided under the terms of an Award Agreement evidencing a Restricted Share Award, the holder of Restricted Shares will generally have rights as a shareholder, including the right to receive dividends on the Shares subject to the award of Restricted Shares during the restriction period and, subject to approval of the Exchange, the right to vote the Shares subject to the award of Restricted Shares. Shares distributed in connection with a share split or share dividend and other property (including cash) distributed as a dividend will be subject to the same restrictions and a risk of forfeiture as the Restricted Shares with respect to which such Shares or other property have been distributed. As a condition to the grant of an Award of Restricted Shares, the Committee may allow a Participant to elect, or may require, that any cash dividends paid on a Restricted Share be automatically reinvested in additional Restricted Shares, applied to the purchase of additional Awards or deferred without interest to the date of vesting of the associated Award of Restricted Shares.

Other Share-Based Awards. The Committee is authorized, subject to limitations under applicable law and approval of the Exchange(s), to grant to Participants such other Awards that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on, or related to, Shares, as deemed by the Committee to be consistent with the purposes of the Plan, including convertible or exchangeable debt securities, other rights convertible or exchangeable into Shares, purchase rights for Shares, Awards with value and payment contingent upon performance of the Corporation or any other factors designated by the Committee, and Awards valued by reference to the book value of Shares or the value of securities of, or the performance of, specified Affiliates. The Committee shall determine the terms and conditions of such Other Share-Based Awards, provided that the Committee shall take all reasonable measures to ensure that the Other Share-Based Awards are not adverse from a tax perspective to any particular Participant. The Committee may impose any conditions or restrictions on the vesting or payout of Other Share-Based Awards as it may deem appropriate, including, without limitation, vesting based upon the Participant’s duration of service to the Corporation or any Affiliate, Performance Criteria, individual performance or other specific criteria, in each case on a specified date or dates or over any period or periods, as determined by the Committee. Shares delivered pursuant to an Other Share-Based Award in the nature of a purchase right granted under this Section 7(g) shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including cash, Shares, other Awards, or other property, as the Committee shall determine.

Cash Awards. The Committee is authorized to grant Cash Awards, on a free- standing basis or as an element of, a supplement to, or in lieu of any other Award under the Plan to Participants in such amounts and subject to such other terms as the Committee in its discretion determines to be appropriate. The Committee may impose any conditions or restrictions on the vesting or payout of Cash Awards as it may deem appropriate, including, without limitation, vesting based upon the Participant’s duration of service to the Corporation or any Affiliate, Performance Criteria, individual performance or other specific criteria, in each case on a specified date or dates or over any period or periods, as determined by the Committee.

Except to the extent prohibited by applicable law and unless otherwise expressly provided in an Award Agreement or in the Plan:

Amendments to the Plan. Subject to the requirements of applicable law, rules and regulations, the Board may amend, alter, suspend, discontinue, or terminate the Plan or any Award without the consent of any shareholder, Participant, other holder or Beneficiary of an Award, or other Person; provided, however, that, subject to the Corporation’s rights to adjust Awards under Sections 8(c), (d) and (e) hereof, any amendment, alteration, suspension, discontinuation, or termination that would impair the rights of any Participant or holder or Beneficiary of any Award previously granted, will not to that extent be effective without the consent of the Participant or holder or Beneficiary of an Award, as the case may be, such consent not to be unreasonably withheld. Notwithstanding any other provision of the Plan or any Award Agreement, without the approval of the shareholders of the Corporation, no amendment, alteration, suspension, discontinuation, or termination will be made that would:

ii.

(A) reduce the Exercise Price or extend the term of an Option or SAR beyond the original term included in the applicable Award Agreement, (B) grant a new Option or SAR in substitution for, or upon the cancelation of, any previously granted Option that has the effect of reducing the Exercise Price thereof, (C) exchange any Option or SAR for Shares, cash, or other consideration when the Exercise Price per Share exceeds the Fair Market Value of a Share, or (D) take any other action that would be considered a “repricing” of an Option or SAR under the Exchange(s), in each case, except as provided in Sections 8(d), (e), or (f);

Without limitation to the generality of the foregoing, Shareholder approval will not be required for any of the following types of amendments:

Amendments to Awards. The Committee may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel, or terminate, any Award previously granted, prospectively or retroactively; provided, however, that, subject to the Committee’s right to adjust Awards under Section 8(c) and (d) hereof, any amendment, alteration, suspension, discontinuation, cancellation, or termination that would impair the rights of any Participant or holder or Beneficiary of any Award previously granted, will not to that extent be effective without the consent of the Participant or holder or Beneficiary of an Award, as the case may be, such consent not to be unreasonably withheld.

Adjustments of Awards upon the Occurrence of Certain Unusual or Nonrecurring Events. Subject to, if applicable, approval of the Exchange(s), the Committee is hereby authorized to make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or non-recurring events (including, without limitation, the events described in Section 5 and 8(e) hereof) affecting the Corporation, any Affiliate, or the financial statements of the Corporation or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that those adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

Recapitalization. In the event of any change in the capital structure or business of the Corporation or other corporate transaction or event that would be considered an “equity restructuring” within the meaning of ASC Topic 718 and, in each case, that would result in an additional compensation expense to the Corporation pursuant to the provisions of ASC Topic 718, if adjustments to Awards with respect to such event were discretionary or otherwise not required (each such an event, an “Adjustment Event”), then the Committee shall equitably adjust (i) the aggregate number or kind of shares that thereafter may be delivered under the Plan, (ii) the number or kind of shares or other property (including cash) subject to an Award, (iii) the terms and conditions of Awards, including the purchase price or Exercise Price of Awards and Performance Criteria, as applicable, and (iv) the applicable limitations with respect to Awards provided in Section 4(b) hereof to equitably reflect such Adjustment Event (“Equitable Adjustments”).

Adjustments. In the event that the Committee determines that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, share split, share dividend, reverse share split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Corporation, issuance of warrants or other rights to purchase Shares or other securities of the Corporation, or other similar corporate transactions or events affect the Shares (which do not constitute an Adjustment Event) such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan and any Awards granted under the Plan, then the Committee may, in any manner as it may deem equitable, subject to, if applicable, approval of the Exchange(s), adjust any or all of: (i) the number and kind of Shares or other securities which thereafter may be made the subject of Awards; (ii) the number and kind of Shares or other securities subject to outstanding Awards; (iii) the Fair Market Value or the grant or Exercise Price with respect to any Award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award; and (iv) the limitations on the number of Shares subject to certain Awards and issuable to insiders and directors provided for in Section 4(b)(i) hereof; provided, however, that the number of Shares subject to any Award denominated in Shares will always be a whole number. Notwithstanding the foregoing, any adjustments made pursuant to this Section 8(e) shall be compliant with all

applicable law and such that the “in- the-money” value of any Option or SAR granted to a Canadian Participant hereunder shall not be increased, that all Options granted to a Canadian Participant are continuously governed by section 7 of the Tax Act, that all SARs granted to a Canadian Participant are continuously not subject to the definition of “salary deferral arrangement” in subsection 248(1) of the Tax Act, and all Restricted Share Units and Deferred Share Units granted to a Canadian Participant shall continuously meet the requirements to be exempted from the definition of “salary deferral arrangement” in subsection 248(1) of the Tax Act.

Substitution Following a Transaction. Awards may also be granted under the Plan in substitution for awards held by individuals who become Participants as a result of a merger, consolidation or acquisition of another entity or the assets of another entity by or with the Corporation or an Affiliate. Such substituted Awards referred to in the immediately preceding sentence that are Options or SARs may have an Exercise Price or grant price that is less than the Fair Market Value of a Share on the date of the substitution if such substitution complies with applicable laws (including tax laws) and Exchange rules.

Forms of Payment under Awards. Subject to the terms of the Plan and of any applicable Award Agreement, payments or transfers to be made by the Corporation or an Affiliate upon the grant, exercise, surrender, redemption, or payment of an Award may be made in such form or forms as the Committee will determine, including, without limitation, cash, Shares, other securities, other Awards, or other property, or any combination thereof and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case in accordance with rules and procedures established by the Committee and applicable law. Such rules and procedures may include, without limitation, provisions for the payment or crediting of reasonable interest on installment or deferred payments.

Share Certificates. All certificates for Shares delivered under the Plan pursuant to any Award or the exercise or redemption thereof will be subject to any stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of Canadian securities regulators, the SEC, the Exchange(s), and any applicable federal, state, provincial or territorial securities laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. If Shares are issued in book entry form, a notation to the same restrictive effect will be placed on the transfer agent’s books in connection with such Shares.

No Shareholder Rights. Under no circumstances shall any Award, other than Share Awards and Restricted Shares, made under the Plan be considered Shares or other securities of the Corporation and no Participant shall be considered the owner of Shares as a result of the grant of any Award other than Share Awards and Restricted Shares (subject to the restrictions provided in the Award Agreement pursuant to which the Restricted Shares were granted). Further, no Award other than a Share Award (or an Award of Restricted Shares, but only to the extent voting rights are approved by the Exchange and further subject to Section 9(o) of the Plan and the Award Agreement pursuant to which the Restricted Shares were granted) shall entitle any Participant to exercise voting rights or any other rights attaching to the ownership of Shares or other securities of the Corporation, including, without limitation, entitlement to receive dividends or other distributions, or rights on liquidation.

The Corporation or any Affiliate is authorized to deduct or withhold from any Award granted, from any payment due or transfer made under any Award or under the Plan or from any compensation or other amount owing to a Participant such amount as may be necessary so as to ensure the Corporation and any Affiliate will be able to comply with the applicable provisions of any federal, provincial, state, or local law relating to the withholding of tax or other required deductions (the “Applicable Withholding Taxes”), and to take any other action as may be necessary in the opinion of the Corporation or Affiliate, acting reasonably, to satisfy all obligations for the payment of those Applicable Withholding Taxes, including, for greater certainty, requiring a Participant, as a condition to the exercise or redemption of an Award, to pay or reimburse the Corporation or Affiliate, as applicable, for any Applicable Withholding Taxes. The Committee shall determine, in its sole discretion, the form of payment acceptable for such tax withholding obligations, including the delivery of cash or cash equivalents, Shares (including through delivery of previously owned Shares (other than, in the case of Canadian Participants, Shares previously issued upon the exercise of an Option within the preceding twenty-four (24)-month period), net settlement, a broker-assisted sale, or other cashless withholding or reduction of the amount of Shares otherwise issuable or delivered pursuant to the Award), other property, or any other legal consideration the Committee deems appropriate. Any determination made by the Committee to allow a Participant who is subject to Rule 16b-3 to pay taxes with Shares through net settlement or previously owned Shares shall be approved by either a committee made up of solely two or more Qualified Members or the full Board. If such tax withholding amounts are satisfied through net settlement or previously owned Shares, the maximum number of Shares that may be so withheld or surrendered shall be the number of Shares that have an aggregate Fair Market Value on the date of withholding or surrender equal to the aggregate amount of such tax liabilities determined based on the greatest withholding rates for federal, state, foreign, and/or local tax purposes, including payroll taxes, that may be utilized without creating adverse accounting treatment for the Corporation with respect to such Award, as determined by the Committee.

The Corporation or Affiliate may sell any Shares, other securities or property withheld, in such manner and on such terms as it deems appropriate, and shall apply the proceeds of such sale to the payment of Applicable Withholding Taxes or other amounts, and shall not be liable for any inadequacy or deficiency in the proceeds received or any amounts that would have been received, had such Shares, other securities or property been sold in a different manner or on different terms.

Collection of Personal Information. Each Participant shall provide the Corporation, the Board, and the Committee with all information they require in order to administer the Plan. The Corporation, any Affiliate, the Board, and the Committee may from time to time transfer or provide access to such information to a third party service provider for purposes of the administration of the Plan provided that such service providers will be provided with such information for the sole purpose of providing such services to the Corporation. By participating in the Plan, each Participant acknowledges that information may be so provided and agrees to its provision on the terms set forth herein. Except as specifically contemplated in this Section 9(l), the Corporation, any Affiliate, the Board and the Committee shall not disclose the personal information of a Participant except: (i) in response to regulatory filings or other requirements for the information by a governmental authority with jurisdiction over the Corporation; (ii) for the purpose of complying with a subpoena, warrant or other order by a court, Person, or body having jurisdiction to compel production of the information; or (iii) as otherwise required by law. In addition, personal information of Participants may be disclosed or transferred to another party during the course of, or completion of, a change in ownership of, or the grant of a security interest in, all or a part of the Corporation or its Affiliates including through an asset or share sale, or some other form of business combination, merger, or joint venture, provided that such party is bound by appropriate agreements or obligations.

Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award under any law deemed applicable by the Committee, that provision will be construed or deemed amended to conform to applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, that provision will be stricken as to that jurisdiction, Person, or Award and the remainder of the Plan and any such Award will remain in full force and effect.

Conditions to Delivery of Shares. Nothing herein or in any Award Agreement shall require the Corporation to issue any Shares with respect to any Award if that issuance would, in the opinion of counsel for the Corporation, constitute a violation of the Securities Act, any other applicable law, or the rules of the Exchange(s) as then in effect. In addition, each Participant who receives an Award under the Plan shall not sell or otherwise dispose of Shares that are acquired upon grant, exercise, or vesting of an Award in any manner that would constitute a violation of any applicable laws, the Plan, or the rules, regulations, or other requirements of the SEC or the Exchange(s). At the time of any exercise

of an Option, or at the time of any grant of any other Award, the Corporation may, as a condition precedent to the exercise of such Option or settlement of any other Award, require from the Participant (or in the event of his or her death, his or her legal representatives, heirs, legatees, or distributees) such written representations, if any, concerning the holder’s intentions with regard to the retention or disposition of the Shares being acquired pursuant to the Award and such written covenants and agreements, if any, as to the manner of disposal of such Shares as, in the opinion of counsel to the Corporation, may be necessary to ensure that any disposition by that holder (or in the event of the holder’s death, his or her legal representatives, heirs, legatees, or distributees) will not involve a violation of the Securities Act, any other applicable state or federal statute or regulation, or any rule of any applicable securities exchange or securities association, as then in effect.

Clawback. The Plan and all Awards granted hereunder are subject to any written clawback policies that the Corporation, with the approval of the Board or an authorized committee thereof, may adopt either prior to or following the Effective Date, including, but not limited to, any policy adopted to conform to the Dodd- Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the SEC and that the Corporation determines should apply to Awards. Any such policy may subject a Participant’s Awards and amounts paid or realized with respect to Awards to reduction, cancellation, forfeiture, or recoupment if certain specified events or wrongful conduct occur, including an accounting restatement due to the Corporation’s material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy.

Participants in Non-Canadian Jurisdictions. Notwithstanding any provision of the Plan to the contrary, to comply with applicable laws in countries other than Canada in which the Corporation or any Affiliate operates or has employees, officers or directors or other service providers from time to time, or to ensure that the Corporation complies with any applicable requirements of foreign securities exchanges, the Committee, in its sole discretion, shall have the power and authority to: (i) determine which of the Affiliates shall be covered by the Plan; (ii) determine which individuals outside of Canada are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to a Participant outside of Canada to comply with applicable foreign laws or listing requirements of any foreign exchange; (iv) establish sub-plans and modify exercise procedures and other terms and procedures, to the extent such actions may be necessary or advisable (any such sub-plans and/or modifications shall be attached to the Plan as schedules), provided, however, that no such sub-plans and/or modifications shall increase the Share limitations contained in Section 4 of the Plan; and (v) take any action, before or after an Award is granted, that it deems advisable to comply with any applicable governmental regulatory exemptions or approval or listing requirements of any such foreign securities exchange. For purposes of the Plan, all references to foreign laws, rules, regulations or taxes shall be references to the laws, rules, regulations and taxes of any applicable jurisdiction other than Canada or a political subdivision thereof.

Blackout Periods. If the date under any Award on which: (i) cash is to be issued in settlement of the Award, or (ii) Performance Criteria are to be evaluated by the Corporation, occurs during a Blackout Period or within three business days of the expiry of a Blackout Period applicable to the relevant Participant, then, subject to Section 7(c)(iv) in respect of Restricted Share Units, the settlement date or evaluation date, as applicable, shall be deemed to be the tenth (10th) business day after expiry of the Blackout Period, or such earlier date following the expiry of the Blackout Period as determined by the Administrator. For Canadian Participants, where a Blackout Period is continuing as of December 15th of the third (3rd) year following the RSU Service Year in respect of Restricted Share Units or as of December 15th of the calendar year following the Eligible Director's Termination Event in respect of the Deferred Share Units, the Restricted Share Units or Deferred Share Units, as the case may be, shall be paid out automatically on such December 15th date. Notwithstanding the foregoing, Shares may be issued in settlement of, or upon exercise of, an Award during a Blackout Period, provided that such Shares are subject to restrictions on trading in accordance with the Corporation’s blackout policy.

This Plan is effective as of the Effective Date. No Awards may be granted under the Plan on and after May 20, 2033. However, any Award granted prior to such termination (or any earlier termination pursuant to Section 8(a) hereof), and the authority of the Board or Committee to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under such Award in accordance with the terms of the Plan, shall extend beyond such termination until the final disposition of such Award.

Supplement to DIRTT Environmental Solutions Ltd. Long Term Incentive Plan for United States Participants

General. This supplement (“Supplement”) to the DIRTT Environmental Solutions Ltd. Second Amended and Restated Long Term Incentive Plan, as such plan may be amended from time to time (the “Plan”) shall apply to Participants who are, in respect of Awards, subject to taxation under the Code (the “U.S. Participants”). In the event of any inconsistency between the Plan and this Supplement, the terms and conditions of this Supplement shall control and govern Awards granted to U.S. Participants, except to the extent necessary to ensure that a U.S. Participant who is also a Canadian Participant or otherwise subject to taxation under the Tax Act in respect of Awards granted under the Plan is not subject to material adverse tax consequences under the Tax Act. Capitalized terms not defined in this Supplement shall have the meaning given to such terms in the Plan, the terms and conditions of which are herein incorporated by reference.

ISOs. The Committee is authorized to grant ISOs to U.S. Participants. Notwithstanding the provisions of Section 7(a) of the Plan, any ISO granted to an individual who owns Shares possessing more than ten percent (10%) of the total combined voting power of all classes of Shares of the Corporation or any of its subsidiaries shall (i) have an exercise price equal to at least one hundred ten percent (110%) of the Fair market Value per Share on the date of grant and (ii) not be exercisable for a period for more than five (5) years following the date of grant of the ISO. The terms of any ISO granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code. ISOs may only be granted to employees of the Corporation or any subsidiary corporation of the Corporation. Except as otherwise provided in Section 8 of the Plan, no term of the Plan relating to ISOs (including any SAR granted in tandem therewith) shall be interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be exercised, so as to disqualify either the Plan or any ISO under Section 422 of the Code, unless notice has been provided to the Participant that such change will result in such disqualification. ISOs shall not be granted more than ten (10) years after the earlier of the adoption of the Plan or the approval of the Plan by the Corporation’s shareholders. Notwithstanding the foregoing, to the extent that the aggregate Fair Market Value of Shares subject to an ISO and the aggregate Fair Market Value of shares of any subsidiary corporation (within the meaning of Section 424(f) of the Code) subject to any other incentive stock options of the Corporation or subsidiary corporation (within the meaning of Section 424(f) of the Code) that are exercisable for the first time by a Participant during any calendar year exceeds one hundred thousand dollars ($100,000), or such other amount as may be prescribed under Section 422 of the Code, such excess shall be treated as Nonstatutory Options in accordance with the Code. As used in the previous sentence, Fair Market Value shall be determined as of the date the ISO is granted. If a Participant shall make any disposition of Shares issued pursuant to an ISO under the circumstances described in Section 421(b) of the Code (relating to disqualifying dispositions), the Participant shall notify the Corporation of such disposition within the time provided to do so in the applicable award agreement. With respect to ISOs, if the Plan does not contain any provision required to be included in the Plan or this Schedule “A” under Section 422 of the Code, that provision shall be deemed to be incorporated herein with the same force and effect as if that provision had been set out at length herein; provided, that to the extent any Option that is intended to qualify as an ISO cannot so qualify, that Option (to that extent) shall be deemed a Nonstatutory Option for all purposes of the Plan.

Section 409A of the Code. It is the general intention, but not the obligation, of the Committee to design Awards to comply with or to be exempt from the limitations and requirements of Section 409A, and Awards will be operated and construed accordingly. Neither this Section 8 nor any other provision of the Plan or this Schedule “A” is or contains a representation to any Participant regarding the tax consequences of the grant, vesting, exercise, settlement, or sale of any Award (or the Shares underlying such Award) granted hereunder, and should not be interpreted as such. In no event shall the Corporation

or Employer be liable for all or any portion of any taxes, penalties, interest, or other expenses that may be incurred by the Participant on account of non-compliance with Section 409A. Notwithstanding any provision in the Plan or an Award Agreement to the contrary, in the event that a “specified employee” (as defined under Section 409A) becomes entitled to a payment under an Award that would be subject to additional taxes and interest under Section 409A if the Participant’s receipt of such payment or benefits is not delayed until the earlier of (a) the date of the Participant’s death, or (b) the date that is six (6) months after the Participant’s Separation from Service, as defined under Section 409A (such date, the “Section 409A Payment Date”), then such payment or benefit shall not be provided to the Participant until the Section 409A Payment Date; provided, however, that if the U.S. Participant is also a Canadian Participant and the Award to be settled is a Restricted Share Unit, such Award must be settled by the date specified in Section 7(c)(iv) of the Plan. Any amounts subject to the preceding sentence that would otherwise be payable prior to the Section 409A Payment Date will be aggregated and paid in a lump sum without interest on the Section 409A Payment Date; provided, however, if the U.S. Participant is also a Canadian Participant, such payment will not be made later than the date specified in Section 7(c)(iv) of the Plan. The applicable provisions of Section 409A are hereby incorporated by reference and shall control over any Plan or Award Agreement provision in conflict therewith; provided, however, in the case of a U.S. Participant that is also a Canadian Participant, if the applicable provisions of Section 409A are contrary to the provisions of the Tax Act, the more restrictive body of law shall control. Notwithstanding any provision of the Plan or any Award Agreement to the contrary, in the event that following the effective date the Committee determines that any Award may be subject to Section 409A, the Committee may adopt such amendments to the Plan and the applicable Award Agreement or adopt other policies and procedures (including amendments, policies, and procedures with retroactive effect), or take any other actions, that the Committee determines are necessary or appropriate to (i) exempt the Award from Section 409A and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (ii) comply with the requirements of Section 409A and thereby avoid the application of any penalty taxes under Section 409A.

10.

Blackout Periods. Notwithstanding the provisions of Section 9(y) of the Plan, where a Blackout Period is continuing as of the last permissible date of payment or settlement under the applicable Award Agreement or this Plan, such Award shall be settled as of such payment or settlement date, irrespective of the continuing Blackout Period, such that (i) any Award that is intended to constitute a “short term deferral” within the meaning of Section 409A will continue to so qualify and (ii) any Award that constitutes deferred compensation subject to Section 409A will be timely paid or settled and shall not incur an excise tax under Section 409A.

The Board of Directors (the “Board”) of DIRTT Environmental Solutions Ltd. (the “Company”) has adopted this Board Mandate and Corporate Governance Guidelines to promote the effective functioning of the Board and its committees (the “Committees”), to promote the interests of the Company as a whole and to ensure a common set of expectations concerning how the Board, its Committees and management should perform their respective functions.

In this Board Mandate and Corporate Governance Guidelines, “applicable securities laws and exchange rules” refers to: (a) the Securities Act (Alberta) and the equivalent thereof in each province and territory of Canada in which the Company is a “reporting issuer” or equivalent thereof, together with the regulations, rules and blanket orders of the securities commission or similar regulatory authority in each of those jurisdictions; (b) the United States Securities Act of 1933, the United States Securities Exchange Act of 1934 (the “U.S. Exchange Act”), and any rules or regulations thereunder; and (c) the rules of each of the Toronto Stock Exchange and The Nasdaq Stock Market LLC, to the extent any securities of the Company are listed on those exchanges

1. ROLE OF THE BOARD AND MANAGEMENT. The Company’s business is conducted by its employees, managers and officers, under the direction of the Chief Executive Officer and the oversight of the Board, to enhance the long-term value of the Company for its shareholders. The Board is elected by the shareholders to oversee management and to act in the best interests of the Company as a whole. Both the Board and management recognize that the long-term interests of the Company and shareholders are advanced by responsibly addressing the concerns of other stakeholders and interested parties, including employees, recruits, customers, suppliers, communities in which the Company operates, government officials and the public at large.

2. FUNCTIONS OF THE BOARD. The Board has four regularly scheduled meetings each year, at which it reviews and discusses reports by management on the Company’s performance, business and prospects, as well as immediate issues facing the Company, and reviews and approves, as applicable, the annual and interim financial statements of the Company.

3. SELECTION OF CHAIRPERSON OF THE BOARD AND CHIEF EXECUTIVE OFFICER. The Board shall select its Chairperson and the Company’s Chief Executive Officer in any way it considers to be in the best interests of the Company.

When the Chairperson is an affiliated director or otherwise not independent under applicable securities laws, a member of the Company’s management, or when the independent directors determine that it is in the best interests of the Company, the independent directors will appoint from among themselves a Lead Independent Director. The Lead Independent Director will: (a) preside at all meetings of the Board at which the Chairperson is not present; (b) preside over each meeting of non-employee Directors; (c) have the authority to call meetings of non-employee Directors; (d) serve as liaison between the Chairperson, the Chief Executive Officer and the non-employee Directors; (e) advise with respect to the Board’s agenda; (f) ensure that the Board is able to function independently of management; (g) serve as the leader of the Board on matters of corporate governance; (h) if requested by major shareholders, ensure his or her availability for direct communication; (i) ensure that all Directors have an independent contact on matters of concern to them and ensure that the Board successfully discharges its fiduciary duties; (j) provide guidance on, and monitor, the independence of each Director to ensure the independence of the Board; (k) provide leadership to the Board if circumstances arise in which the Chairperson has, or may be perceived to have, a conflict; (l) ensure that functions delegated to Board committees are carried out as required and results are reported to the Board; (m) work with the Chairperson and Chief Executive Officer, including helping to review strategies, define issues, maintain accountability and build relationships; (n) in conjunction with the Corporate Governance and Compensation Committee, facilitate the review and assessment of individual Director attendance and performance and the size, composition and overall performance of the Board and its committees; (o) in collaboration with the Chairperson and the Secretary, ensure that information requested by Directors or Board committees is provided and meets their needs; and (p) together with the Chairperson, ensure the Directors are alert to their obligations to the Company, securityholders, management, other stakeholders and pursuant to applicable law. If the Chairperson is an independent director, then the duties for the Lead Independent Director described above shall be part of the duties of the Chairperson.

4. BOARD COMMITTEES. The Board has established the following standing Committees to assist it in discharging its responsibilities: (a) Audit; (b) Corporate Governance and Compensation; (c) Enterprise Risk Management. The current charters of each Committee are published on the Company’s website. Members of each of these Committees (including the Committee Chairs) are appointed by the Board, on the recommendation of the Corporate Governance and Compensation Committee. The Committee Chairs report the highlights of their meetings to the Board following each meeting of their respective Committees. The Committees may hold meetings in conjunction with the Board. The Board may, from time to time, establish additional committees.

5. SELECTION OF DIRECTORS. The Board’s Corporate Governance and Compensation Committee shall be responsible for identifying qualified individuals to become Board members and selecting or recommending to the Board director nominees for each meeting of the shareholders at which one or more directors will be elected and for vacancies the Board chooses to fill.

6. QUALIFICATIONS OF DIRECTORS. Directors must have the highest personal and professional ethics, integrity and values. They must be committed to representing the best interests of the Company. They must have an objective perspective, practical wisdom, mature judgment and expertise, skills and knowledge useful to the oversight of the Company’s business. The Company’s goal is a Board that represents diverse experiences at policy-making levels in business and other areas relevant to the Company’s activities, while encouraging a diversity of backgrounds, including with respect to gender, consistent with the Board’s diversity policy.

Each director should be sufficiently familiar with the business of the Company to ensure active participation in the deliberations of the Board and each Committee on which the director serves. On request, management will make appropriate personnel available to answer any questions a director may have about any aspect of the Company’s business. All directors shall be free to contact the Chief Executive Officer at any time to discuss any aspect of the Company’s business, and shall have complete access to other employees of the Company.

The Company does not believe that arbitrary term limits on director’s service are appropriate, nor does it believe that directors should expect to be re-nominated at the end of each term until they retire. The Board’s self-evaluation process described below is an important factor in determining a Board member’s tenure.

7. INDEPENDENCE STANDARDS. A majority of the Board must be independent, within the meaning of applicable securities laws and exchange rules.

The Board will annually review the relationships between the Company and each director and determine which directors satisfy the applicable independence standards of the Board and of each Committee on which those directors serve under applicable securities laws and exchange rules.

8. SERVICE ON OTHER BOARDS. Members of the Board may serve on the board of directors of other companies so long as these commitments do not materially interfere and are compatible with their ability to fulfill their duties as a member of the Board. A director seeking to serve on the board of directors or advisory board of another for-profit entity (whether public or private) should notify the Chairperson or Lead Director (if appointed).

Without prior approval of the Board, (a) directors may not serve on more than four other Boards of public companies in addition to the Company’s Board, (b) directors who serve as the chief executive officers or in equivalent positions at any company (including the Company) may not serve on the board of more than one public company in addition to the Company’s Board, and (c) no member of the Audit Committee may serve simultaneously on the audit committee of more than two other publicly companies, provided that a member who is a retired certified public accountant, chief financial officer, or controller (or has similar experience) may not serve simultaneously on the audit committee of more than three other publicly-traded companies.

10. DIRECTOR RESPONSIBILITIES. Directors must perform the roles and functions described in this Board Mandate and Corporate Governance Guidelines and the charters of all Committees on which they serve. They must devote sufficient time and resources to carry out their duties and responsibilities effectively. They must make every effort to attend each meeting of the Board and all Committees on which they serve, and they must review all materials distributed to them in advance of each such meeting. In discharging responsibilities as a director, a director is entitled to rely in good faith on reports or other information provided by the Company’s management, independent auditors, and other persons as to matters the director reasonably believes to be within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Company. Attendance by telephone, electronic or other communication facilities as permit all persons participating in the meeting to communicate with each other simultaneously and instantaneously may be used to facilitate a director’s attendance. Directors must comply with all applicable laws, including the applicable securities laws and exchange rules and, with respect to their activities relating to the Company, the Business Corporations Act (Alberta) (the “ABCA”).

11. MEETINGS OF NON-EMPLOYEE DIRECTORS; PRESIDING DIRECTOR. At each regularly scheduled meeting of the Board, the non-employee directors shall also meet separately, without employees present. The Lead Independent Director will preside at such meetings. The non-employee directors may also meet without employees present at other times as determined by the Lead Independent Director. The non-employee directors include all directors who are not employees of the Company or any of its subsidiaries, whether or not they are “independent,” as defined in these Guidelines. If the Chairperson is an independent director, then the duties for the Lead Independent Director described above shall be part of the duties of the Chairperson.

12. AGENDAS. The agenda for each Board meeting shall be established by the Chairperson in collaboration with the Chief Executive Officer, taking into account input and suggestions from other members of the Board and senior management. The agenda for each Committee shall be established by the Chair of each Committee, in consultation with appropriate members of the Committee, advisors and senior management. Unless a Committee expressly determines otherwise, the agenda, materials and minutes for each Committee

meeting shall be available to all directors, and all directors shall be free to attend any Committee meeting. All directors, whether or not members of the Committee, shall be free to make suggestions to a Committee Chair for additions to the agenda of the Chair’s Committee or to request that an item from a Committee agenda be considered by the Board.

14. CODE OF CONDUCT AND ETHICS. The Board expects the Company’s directors, officers and employees to act ethically at all times and to adhere to the Company’s Code of Conduct and Code of Ethics.

The Board will oversee and approve any waivers of the Code of Ethics sought by directors, executive officers, or other members of senior management. In reviewing any such waivers, the Board may consider the recommendations of the Corporate Governance and Compensation Committee. The Board will oversee that any waivers of the Code of Ethics are promptly disclosed to shareholders to the extent required by applicable securities laws and exchange rules. The Company will post and disclose the Code of Ethics as required by applicable securities laws and exchange rules.

15. COMPENSATION OF BOARD. Periodically, the Board will determine the form and amount of non-employee director compensation, based on the review and recommendation of the Corporate Governance and Compensation Committee. The Committee will be guided by three principles: (a) the compensation should fairly pay non-employee directors for the work required in light of the Company’s size and scope; (b) compensation should align the directors’ interests with the long-term best interests of the Company; and (c) the structure of the compensation should be simple, transparent and easy for shareholders to understand.] [At the end of each year, the Corporate Governance and Compensation Committee will review non-employee director compensation and benefits.

16. SHARE OWNERSHIP GUIDELINES. The Board believes that, in order to align the interests of directors and shareholders, directors should have a financial stake in the Company. Each director is expected to comply with the Company’s equity ownership guidelines, as established from time to time. The Board will evaluate whether exceptions should be made for any director on the basis of financial hardship.

21. SELF-EVALUATION. The Board will perform an annual self-evaluation as to the effectiveness of the Board, all Committees, and each individual director. Such assessments will address, at a minimum, the effectiveness and adequacy of meetings of the Board and its Committees, the adequacy and timeliness of information provided to the Board by the Company’s management, and the diversity of experience of individual directors and the contributions of each director. The Board may use the results of the evaluation processes in assessing individual directors’ suitability for nomination and in assessing the overall structure and functioning of the Board and the committees of the Board.

22. SUCCESSION PLAN. The Board will approve and maintain a succession plan for the Chief Executive Officer and other senior management, based on recommendations from the Corporate Governance and Compensation Committee. Such plan will include policies and principles for selecting and evaluating a new Chief Executive Officer in the event of an emergency or retirement of the Chief Executive Officer.

23. ACCESS TO INDEPENDENT ADVISORS. The Board has the authority at any time to retain independent outside financial, legal or other advisors.

24. DIRECTOR ORIENTATION AND EDUCATION. The Chief Financial Officer will provide an orientation for new directors, and periodically provide materials or briefing sessions for all directors on subjects relevant to their discharge of their duties.

		or exchange for awards previously granted by a company acquired by the Company or any subsidiary or with which the Company or any subsidiary combines.
Change of Control		▪ In the event of a change of control, if the successor entity does not assume the outstanding awards or substitute similar awards on the same terms and conditions as the original awards, the vesting of all outstanding awards will be accelerated in full with effect immediately prior to the change of control (vesting for performance-based awards will be measured and calculated assuming target performance was achieved).
Amendments		▪ The Board may amend, alter, suspend, discontinue or terminate the LTIP or any award without the consent of any shareholder, participant, holder or beneficiary of an award or other person; provided that such amendment, alteration, suspension, discontinuation or termination does not impair the rights of a participant, holder or beneficiary (subject to the Company’s rights to adjust awards in connection with certain recapitalizations, restructurings, and related transactions).
		▪ The Board may amend the LTIP without shareholder approval as follows: (i) amendments for the purpose of curing any inconsistency, ambiguity, error, or omission in the LTIP or award, (ii) as necessary to comply with applicable laws, (iii) amendments of a “housekeeping” nature, (iv) amendments intended to comply with changes in tax or regulatory requirements, or (v) a change to the termination provisions of awards which does not entail an extension beyond the original expiry date of such award.
		▪ Shareholder approval is required for any amendment that would (i) increase the total number of Common Shares available for awards under the LTIP, (ii) amend any outstanding option or share appreciation right to reduce its exercise price, extend its term beyond the original term set forth in the applicable award agreement or take any other action that would be considered a repricing under the applicable stock exchange listing standards, (iii) remove or exceed the insider participation limits, (iv) increase the non-employee director compensation limits, (v) have the effect of amending the section of the LTIP that enumerates what actions require approval of shareholders, (vi) modify or amend the provisions of the LTIP in any manner that would permit awards to be transferable or assignable in a manner other than as currently provided in the LTIP, (vii) change eligible Participants under the LTIP, which would have the effect of broadening or increasing insider participation, or (viii) otherwise cause the LTIP to cease to comply with any tax or regulatory requirement.
General		▪ Participants may not assign, alienate, pledge, attach, sell or otherwise transfer or encumber any award, other than an award of fully vested shares, except by will or the laws of descent or by the designation of a beneficiary.
		▪ All awards are subject to any written clawback policy of the Company adopted from time to time.
