GREENBROOK TMS INC.

ANNUAL MEETING OF SHAREHOLDERS

May 11, 2023

NOTICE OF ANNUAL MEETING OF SHAREHOLDERS

NOTICE IS HEREBY GIVEN that an Annual Meeting of the Shareholders (the “Meeting”) of Greenbrook TMS Inc. (“Greenbrook” or the “Company”) will be held on Tuesday, June 20, 2023 at 10:00 a.m. (Toronto time) by way of virtual-only meeting via live webcast.

Meeting Business

The Meeting will be held for the following purposes:

1. to receive the annual consolidated financial statements of Greenbrook for the fiscal year ended December 31, 2022, and the auditors’ report thereon;

2. to elect members of the Board of Directors of Greenbrook (see “Business to be Transacted at the Meeting – Election of the Board of Directors”);

3. to appoint Greenbrook’s auditors and to authorize the directors to fix the auditors’ remuneration (see “Business to be Transacted at the Meeting – Appointment of the Auditors”); and

4. to transact such other business as may properly be brought before the Meeting or any adjournment or postponement thereof.

Record Date

You have the right to receive notice of and vote at the Meeting as set out in the accompanying Management Information Circular if you are a Greenbrook shareholder as of the close of business on May 5, 2023.

Meeting Format

The Board of Directors has determined that it is desirable and in the best interest of the Company, the shareholders and the Company’s other stakeholders to again hold this year’s Meeting exclusively by electronic means via live webcast. We hope that hosting a virtual meeting will enable greater participation by our shareholders by allowing shareholders who might not otherwise be able to travel to a physical meeting to attend online. Shareholders and duly appointed proxyholders will be able to listen to, participate in, ask questions, and vote at the Meeting in real time through a web-based platform instead of attending the Meeting in person.

You can attend the Meeting by joining the live webcast online at www.virtualshareholdermeeting.com/GTMS2023. See “Voting Information” in the accompanying Management Information Circular for detailed instructions on how to attend and vote at the Meeting.

Management currently intends on only proceeding with the formal items of business of the Meeting without any opening remarks or subsequent management presentations. However, shareholders will still have the opportunity to submit questions during the Meeting through the live webcast.

Your Vote is Important

As a Greenbrook shareholder, it is important that you read the accompanying Management Information Circular carefully.

You are entitled to vote either by proxy or at the Meeting by online ballot through the live webcast platform. If you are unable to attend the Meeting, you are requested to vote your shares online or by using the enclosed form of proxy or voting instruction form.

Registered shareholders (whose Greenbrook shares are registered in their name) should vote online at www.proxyvote.com or complete and sign the enclosed form of proxy and return it in the envelope provided. Proxies must be received by Broadridge Investor Communications Corporation at Data Processing Centre, P.O. Box 3700 STN Industrial Park, Markham, ON, L3R 9Z9, by no later than 5:00 p.m. (Toronto time) on June 16, 2023.

Non-registered beneficial shareholders (whose Greenbrook shares are held indirectly through an intermediary such as a bank, trust company, securities broker or other intermediary) should review the voting instruction form provided by their intermediary, which sets out the procedures to be followed for voting shares held through intermediaries.

If you wish to appoint a proxyholder other than Sasha Cucuz or Bill Leonard, each of whom is a director of Greenbrook, you must create an appointee name and an eight (8) character appointee identification number, either online at www.proxyvote.com or in your form of proxy or voting instruction form. This applies to both registered and non-registered shareholders. If you do not provide your proxyholder with the exact appointee name and eight (8) character appointee identification number you created, your proxyholder will not be able to vote at the Meeting.

Greenbrook believes that the ability to participate in the Meeting in a meaningful way remains important despite the decision to hold this Meeting through electronic means. Shareholders will have substantially the same opportunity to vote and submit questions on matters of business at the Meeting as in past years when shareholders meetings were held in person.

For those that plan on accessing the live webcast, please allow ample time prior to the Meeting. The Meeting will begin promptly at 10:00 a.m. (Toronto time) on Tuesday, June 20, 2023, unless otherwise adjourned or postponed. Once logged in to the webcast, it is important to remain connected to the internet for the duration of the Meeting.

By Order of the Board of Directors,

	/s/ Bill Leonard

Unless otherwise indicated, all references to “$” or “dollars” in this Circular refer to United States dollars.

Your proxy is being solicited by management of Greenbrook for the items described in the Notice of Meeting on the previous page. We pay for all costs associated with soliciting your proxy. We usually make our request by mail, but we may also solicit your proxy by telephone.

As a Shareholder, you have the right to electronically attend and vote at the Meeting as set out in this Circular. Please read this Circular, as it gives you information that you will need to know in order to cast your vote. We also encourage you to read Greenbrook’s management’s discussion and analysis and annual consolidated financial statements for the fiscal year ended December 31, 2022 (“Fiscal 2022”), included in the Company’s annual report on Form 20-F for Fiscal 2022 (the “Annual Report”).

On January 12, 2021, at a special meeting of Shareholders, our Shareholders approved a special resolution authorizing our board of directors (the “Board”) to amend our articles of incorporation (the “Articles”) to effect a consolidation (the “Share Consolidation”) of all of the issued and outstanding Shares, such that the trading price of the Shares following the Share Consolidation would permit us to qualify for listing on the Nasdaq Capital Market of The Nasdaq Stock Market LLC (the “Nasdaq”). On February 1, 2021, the Board effected the Share Consolidation on the basis of one post-consolidation Share for every five pre-consolidation Shares and on February 4, 2021 the Shares began trading on a post-consolidation basis on the Toronto Stock Exchange (“TSX”). The Shares began trading on the Nasdaq on March 16, 2021. On March 13, 2023, the Company voluntarily delisted the Shares from the TSX and the Shares remain listed on the Nasdaq.

Unless otherwise indicated, all Share numbers in this Circular have been adjusted to give effect to the Share Consolidation.

BUSINESS TO BE TRANSACTED AT THE MEETING

The following business will be transacted at the Meeting:

Receiving the Annual Financial Statements

●      Management will present the annual financial results at the Meeting.

Election of the Board of Directors

●      Eight director nominees are proposed for election to the Board. Shareholders may vote on the election of the directors.

Appointment of the Auditors

●     The Board recommends the re-appointment of KPMG LLP as Greenbrook’s auditors. Shareholders may vote on the re-appointment of the auditors and the authorization of the Board to fix such auditors’ remuneration.

Receiving the Annual Financial Statements

Our audited consolidated financial statements for the fiscal year ended December 31, 2022, including the auditors’ report thereon, have been prepared and will be sent to registered and beneficial Shareholders who have requested that these materials be sent to them. Our audited consolidated financial statements are included in the Annual Report, which is available on SEDAR at www.sedar.com, on EDGAR at www.sec.gov and on our website at www.greenbrooktms.com.

Election of the Board of Directors

The Board is presently comprised of ten directors; however, the Board has determined that in furtherance of the Company’s previously-announced restructuring plan, the business of the Company may be properly conducted by a board of directors consisting of eight directors and has, therefore, reduced the size of the Board from ten to eight, effective at the close of the Meeting.

In furtherance of the foregoing, directors Robert Higgins and Adele C. Oliva have each decided not to stand for re-election to the Board. The Company thanks each of them for their many significant contributions in helping to guide and grow the business. Furthermore, Marlin Fund, Limited Partnership, Marlin Fund II, Limited Partnership and MSS GB SPV LP, as a group (collectively, “Masters”), and 1315 Capital II, LP (“1315 Capital”) have each waived their director nomination rights in respect of the Meeting. See “Election of Directors – General” for more information.

Accordingly, the Board recommends that you vote FOR the election of each of the following persons who have been proposed by the Board for election as directors by the Shareholders:

· Brian P. Burke

· Colleen Campbell

· Adrienne Graves, Ph.D.

· Bill Leonard

· Frank Tworecke

· Elias Vamvakas

The Board also recommends that you vote FOR the election of the following person who has been nominated by Greybrook Health Inc. (“Greybrook Health”) and who has been proposed by the Board for election as a director by the Shareholders:

· Sasha Cucuz

The Board also recommends that you vote FOR the election of the following person who has been nominated by Benjamin Klein and who has been proposed by the Board for election as a director by the Shareholders:

· Benjamin Klein

See “Election of Directors” on page 7 for more information.

Directors appointed at the Meeting will serve, subject to our Articles and the Business Corporations Act (Ontario) (the “OBCA”), until the end of the next annual shareholders meeting or until their successors are elected or appointed. All of the proposed directors are currently directors of Greenbrook.

Appointment of the Auditors

If you are a Shareholder, you can vote on the appointment of the auditors and authorizing the Board to set the auditors’ remuneration. The Board recommends that you vote FOR the re-appointment of our current auditors, KPMG LLP, Chartered Professional Accountants, Licensed Public Accountants, as our auditors, and authorizing the Board to set KPMG LLP’s remuneration.

The auditors will serve until the end of the next annual shareholders meeting or until a successor is appointed. KPMG LLP has been our auditors since 2017.

Considering Other Business

We will consider any other business that may properly come before the Meeting. As of the date of this Circular, we are not aware of any changes to the items above or any other business to be considered at the Meeting. If there are changes or new items, you or your proxyholder can vote your Shares on these items as you or your proxyholder sees fit. If any other matters properly come before the Meeting, it is the intention of the persons named in the form of proxy to vote in respect of those matters in accordance with their judgment.

VOTING INFORMATION

We are authorized to issue an unlimited number of Shares. As of May 5, 2023, there were 40,800,180 issued and outstanding Shares.

Each Share you own as of the close of business on May 5, 2023, the record date for the Meeting, entitles you to one vote on each of the matters to be acted upon at the Meeting, or any adjournment or postponement thereof, either by proxy or at the Meeting by online ballot through the live webcast platform. The right to vote at the Meeting is limited to Shareholders who own Shares as of the above record date for the Meeting.

To the knowledge of the directors and officers of Greenbrook, the following are the only persons or companies who beneficially own, directly or indirectly, or exercise control or direction over more than 10% of the total outstanding Shares:

How to Vote

Registered Shareholder Voting

You are a registered shareholder (“Registered Shareholder”) if your name appears on your Share certificate or on the register maintained by our transfer agent, Computershare Investor Services Inc. Your proxy form indicates if you are a registered shareholder. If you are a Registered Shareholder, you may vote at the Meeting by online ballot through the live webcast platform or by proxy in advance of the Meeting. See below for details on each voting option.

Voting at the Meeting

If you are a Registered Shareholder and you wish to vote your Shares at the Meeting, you do not need to complete and return the form of proxy. Your vote will be taken by electronic ballot and counted at the virtual Meeting. See “How to Attend and Participate at the Virtual Meeting” below.

Voting by Proxy

Registered Shareholders have three options to vote by proxy:

· On the Internet in advance of the Meeting

Visit www.proxyvote.com or scan the QR code on the form of proxy to access the website and follow the instructions on screen. You will need your 16-digit control number (located on both sides of the form of proxy) to identify yourself to the system. If you are voting through the internet, all required information must be entered by 5:00 p.m. (Toronto time) on June 16, 2023.

· By Mail

Complete, date and sign the enclosed form of proxy and return it to Broadridge Investor Communications Corporation (“Broadridge”) at: Data Processing Centre, P.O. Box 3700 STN Industrial Park, Markham, ON L3R 9Z9, in the envelope provided so that it arrives no later than 5:00 p.m. (Toronto time) on June 16, 2023. This will ensure your vote is recorded.

· By Telephone

Call 1-800-474-7493 (English) or 1-800-474-7501 (French) and follow the instructions. You will need your 16-digit control number (located on the front of the form of proxy) to identify yourself to the system. If you are voting by telephone, all required information must be entered by 5:00 p.m. (Toronto time) on June 16, 2023. If you vote by telephone, you cannot appoint anyone other than the directors named on your proxy form as your proxyholder.

Signing the enclosed form of proxy gives authority to Sasha Cucuz or Bill Leonard, each of whom is a director of Greenbrook, to vote your Shares at the Meeting. You may appoint someone other than the above-named directors to vote your Shares by writing the name of the person that you wish to appoint, who need not be a Shareholder, in the blank space provided on the form of proxy. It is important to ensure that any other person you appoint is attending the Meeting and is aware that he or she has been appointed to vote your Shares.

If you appoint someone other than the above-named directors as your proxyholder, you must create an appointee name and an eight (8) character appointee identification number, either online at www.proxyvote.com or on your form of proxy. If you do not provide your proxyholder with the exact appointee name and eight (8) character appointee identification number you created, your proxyholder will not be able to vote at the Meeting.

The persons named on the form of proxy must vote or withhold from voting your Shares in accordance with your directions. In the absence of such directions, proxies received by management will be voted in favor of the election of directors to the Board and the appointment of the auditors and authorizing the directors to set the auditors’ remuneration.

3

The persons named in the form of proxy will have discretionary authority with respect to amendments or variations to matters identified in the Notice of Annual Meeting of Shareholders and with respect to other matters which may properly come before the Meeting.

As of the date of this Circular, management of Greenbrook knows of no such amendment, variation or other matter expected to come before the Meeting. If any other matters properly come before the Meeting, the person named in your form of proxy will vote on them in accordance with their best judgment.

Revoking Your Proxy

If you are a Registered Shareholder and wish to revoke your proxy, you may revoke a vote you made by proxy by:

· voting again online at www.proxyvote.com or by completing and signing a proxy bearing a later date and depositing it in accordance with the instructions on the form of proxy, which will revoke any proxy you previously submitted;

· voting at the virtual Meeting by submitting an online ballot through the live webcast platform, which will revoke any proxy you previously submitted; or

· making a request in writing stating that you wish to revoke your proxy, before any vote in respect of which the proxy has been given or taken.

Non-Registered or Beneficial Shareholder Voting

Information in this section is very important to non-registered or beneficial owners of Shares. You are a non-registered or beneficial owner if your Shares are held in the name of an intermediary such as a bank, trust company, securities broker, depository (such as CDS Clearing and Depository Services Inc. or The Depository Trust Company) or other intermediary (“Beneficial Shareholder”). Applicable Canadian securities laws require intermediaries to seek voting instructions from Beneficial Shareholders. Accordingly, you will have received from your intermediary a voting instruction form for the number of Shares you hold.

Voting at the Meeting

A Beneficial Shareholder who receives a voting instruction form from their intermediary cannot use that voting instruction form to vote Shares directly at the virtual Meeting. To vote your Shares at the Meeting by online ballot through the live webcast platform, your intermediary must appoint you as proxyholder. In order to be appointed as proxyholder, insert your name in the space provided on the voting instruction form and follow the return instructions provided by your intermediary. In addition, you must create an appointee name and an eight (8) character appointee identification number, either online at www.proxyvote.com or on your voting instruction form. If you do not create an appointee name and eight (8) character appointee identification number, you will not be able to vote at the Meeting. You do not need to fill in the voting directions as your vote will be taken at the Meeting. The voting instruction form must be returned to your intermediary well in advance of the Meeting in order to appoint your proxyholder.

4

If you are a Beneficial Shareholder holding your Shares through a U.S. bank, broker or dealer, you must also obtain a valid legal proxy from your broker, bank, dealer or other agent and then register in advance to attend the virtual Meeting. Follow the instructions from your broker, bank, dealer or other agent included with these proxy materials, or contact your broker, bank, dealer or other agent to request a legal proxy form.

Voting Instruction

Beneficial Shareholders who do not wish to vote at the Meeting by online ballot through the live webcast platform are still encouraged to vote their Shares. You can do so by following the instructions on the voting instruction form provided by your intermediary. The voting instruction form must be returned to your intermediary well in advance of the Meeting in order to have the Shares voted.

Each intermediary has its own procedures, which should be carefully followed to ensure that your Shares are voted at the Meeting. The persons named on the voting instruction form must vote or withhold from voting your Shares in accordance with your directions. In the absence of such directions, voting instruction forms received will be voted in favor of the election of directors to the Board and the appointment of the auditors and authorizing the directors to set the auditors’ remuneration.

The persons named in the voting instruction form you receive will have discretionary authority with respect to amendments or variations to matters identified in the Notice of Annual Meeting of Shareholders and with respect to other matters which may properly come before the Meeting.

If you are a Beneficial Shareholder and have not received a package containing a voting instruction form or form of proxy, please contact your intermediary.

As of the date of this Circular, management of Greenbrook knows of no such amendment, variation or other matter expected to come before the Meeting. If any other matters properly come before the Meeting, the persons named in the voting instruction form will vote on them in accordance with their best judgment.

Revoking Your Voting Instruction

If you are a Beneficial Shareholder and wish to revoke your voting instructions, please contact your intermediary well in advance of the Meeting.

Delivery of Proxy-Related Materials

Proxy-related materials will be sent by Greenbrook to the intermediaries and not directly to Beneficial Shareholders. Greenbrook intends to pay for intermediaries to deliver proxy-related materials and Form 54-101F7 (request for voting instructions) to “objecting beneficial owners”.

· Step 2: Follow the instructions below:

Registered Shareholders and Beneficial Shareholders who have not appointed themselves as proxyholders: Click “Login” and then enter your control number. The 16-digit control number located on both sides of your form of proxy or voting instruction form is your control number. For Registered Shareholders, if you use your control number to log in to the Meeting, any vote you cast at the Meeting will revoke any proxy you previously submitted. If you do not wish to revoke a previously submitted proxy, you should not vote at the Meeting. If you are a Beneficial Shareholder who has not appointed yourself as a proxyholder, you will not be able to vote at the Meeting, but you will be able to ask questions.

Duly appointed proxyholders (including Beneficial Shareholders who have appointed themselves as proxyholders): Click “Login” and then enter the appointee name and the eight (8) character appointee identification number provided to you by the Shareholder who appointed you.

Guests: Click “Guest” and then complete the online form.

Registered Shareholders and duly appointed proxyholders may attend and ask questions at the Meeting and vote by completing a ballot online during the Meeting. Beneficial Shareholders who have not duly appointed themselves as proxyholders may attend and ask questions at the Meeting. Guests may attend the Meeting, but will not be permitted to vote or ask questions.

We recognize the importance of Shareholders being able to ask questions in a virtual meeting format. At the virtual Meeting, Registered Shareholders and duly appointed proxyholders, regardless of geographic location, will be able to participate and have an equal opportunity to ask questions, and vote in real time at the Meeting, provided they are connected to the internet and have logged into the online platform accessible at www.virtualshareholdermeeting.com/GTMS2023. To ask a question during the Meeting you may write through the live webcast after logging-in, type your question into the “Ask a Question” field, and click “Submit”. We strongly encourage you to submit your questions as early as possible during the Meeting as we intend to answer questions in the order in which they are submitted to us by Shareholders. Questions submitted via the online platform that relate to the business of the Meeting are expected to be addressed in the question-and-answer section of the Meeting. Such questions will be read by the Chair of the Meeting or a designee of the Chair and responded to by a representative of the Company as they would be at in-person Shareholder meetings. Questions submitted via the online platform will be moderated before being sent to the Chair of the Meeting. This is to avoid repetition and to ensure an orderly Meeting. The Chair of the Meeting will decide on the amount of time allocated to each question and will have the right to limit or consolidate questions and to reject questions that do not relate to the business of the Meeting or which are determined to be inappropriate or otherwise out of order. Questions can be submitted at any time as prompted by the Chair during the Meeting until the Chair closes the session. It is anticipated that Shareholders and duly appointed proxyholders attending the Meeting virtually will have substantially the same opportunity to ask questions on matters of business before the Meeting as if the Meeting was held in person.

If you plan to vote at the Meeting, 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 internet connectivity for the duration of the Meeting. The Meeting will begin promptly at 10:00 a.m. (Toronto time) on Tuesday, June 20, 2023, unless otherwise adjourned or postponed. For those that plan on attending the Meeting via the live webcast platform, you should allow ample time to log in to the Meeting online and complete the check-in procedures.

The Articles provide that the Board shall consist of a minimum of three (3) and a maximum of fifteen (15) directors. The Board determines the number of directors to be elected at a meeting of Shareholders. The Board has determined that, at the present time, there will be eight (8) directors, each of whom is to be elected at this Meeting and who will hold office until the end of the next annual meeting of Shareholders or until their successors are elected or appointed.

The director biographies on pages 9 to 14 of this Circular describe the directors who are proposed for election, along with their ownership of securities of the Company.

Pursuant to an investor rights agreement among the Company, Greybrook Health, 1315 Capital and Masters (the “2021 Investor Rights Agreement”) entered into on June 14, 2021, Greybrook Health, 1315 Capital and Masters were each granted the right to nominate one director for so long as such party (including its permitted affiliates) owns, controls or directs 5% or more of the Company’s outstanding Shares.

Pursuant to an investor rights agreement between the Company and Benjamin Klein (the “Klein Investor Rights Agreement” and, together with the 2021 Investor Rights Agreement, the “Investor Rights Agreements”) entered into on July 14, 2022, Benjamin Klein was granted the right to nominate one director for so long as Mr. Klein (including its permitted affiliates) owns, controls or directs 5% or more of the Company’s outstanding Shares.

Pursuant to the Investor Rights Agreements, Greybrook Health, 1315 Capital, Masters and Benjamin Klein each exercise their respective nomination rights by submitting their nominees to the Board, which reviews the proposed nominations together with the remaining director nominations, determined solely by the Board or the Governance and Nominating Committee, to be elected by the Shareholders at the Meeting. 1315 Capital and Masters have each waived their director nomination rights in respect of the Meeting.

The foregoing summary is qualified in its entirety by reference to the provisions of the Investor Rights Agreements. Copies of the Investor Rights Agreements are available under the Company’s profile on SEDAR at www.sedar.com and have been filed as exhibits to the Annual Report filed on EDGAR at www.sec.gov. In addition, a summary of further details has been included in the Annual Report, which is also available under the Company’s profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

All nominees have established their eligibility and willingness to serve as directors. Five of the eight nominees are independent within the meaning of applicable securities laws and stock exchange rules. All nominees are currently directors of Greenbrook. Management does not believe that any of the nominees will be unable to serve as a director, but if that should occur for any reason prior to the Meeting, the persons named in the accompanying form of proxy (or voting instruction form) may vote for another nominee at their discretion (subject to the nomination rights as described above). Each director shall hold office until the next annual meeting of Shareholders or until the director resigns or a successor is elected or appointed.

Advance Notice Provisions

We have included certain advance notice provisions with respect to the election of our directors in our by-laws (the “Advance Notice Provisions”). The Advance Notice Provisions are intended to: (a) facilitate orderly and efficient annual general meetings or, where the need arises, special meetings of our Shareholders; (b) ensure that all Shareholders receive adequate notice of Board nominations and sufficient information with respect to all nominees; and (c) allow Shareholders to register an informed vote. Only persons who are nominated by Shareholders in accordance with the Advance Notice Provisions will be eligible for election as directors at any annual meeting of Shareholders, or at any special meeting of Shareholders if one of the purposes for which the special meeting was called was the election of directors.

Under the Advance Notice Provisions, a Shareholder wishing to nominate a director would be required to provide us notice, in the prescribed form, within the prescribed time periods. These time periods include (a) in the case of an annual meeting of Shareholders (including annual and special meetings), not less than 30 days prior to the date of the annual meeting of Shareholders; provided that, if the first public announcement of the date of the annual meeting of Shareholders (the “Notice Date”) is less than 50 days before the meeting date, not later than the close of business on the 10^th day following the Notice Date and (b) in the case of a special meeting (which is not also an annual meeting) of Shareholders called for any purpose which includes electing directors, not later than the close of business on the 15^th day following the Notice Date, provided that, in either instance, if notice-and-access (as defined in National Instrument 54-101 – Communication with Beneficial Owners of Securities of a Reporting Issuer) is used for delivery of proxy related materials in respect of a meeting described above, and the Notice Date in respect of the meeting is not less than 50 days prior to the date of the applicable meeting, the notice must be received not later than the close of business on the 40^th day before the applicable meeting.

A copy of our by-laws are available under the Company’s profile on SEDAR at www.sedar.com.

Individual and Majority Voting Policy

The Board believes that each of its members should carry the confidence and support of our Shareholders. To this end, the Board has adopted an individual and majority voting policy that requires that Shareholders be able to vote in favor of, or withhold from voting, separately for each nominee for director and that, in an uncontested election of directors, any nominee for director who receives a greater number of votes “withheld” from his or her election than votes “for” such election must immediately tender his or her resignation to the Chair of the Board following the applicable meeting or, if the affected director is the Chair, to each member of the GN Committee (as defined herein). Any resignation received by the Chair of the Board will be promptly referred to the GN Committee for consideration. An “uncontested election” means an election where the number of nominees for directors is equal to the number of directors to be elected.

The GN Committee will, promptly following the resignation but in any event within 30 days of the applicable Shareholders’ meeting, consider the offer of resignation and will recommend to the Board whether or not to accept it. The GN Committee will recommend that the Board accept the resignation absent exceptional circumstances that would warrant the applicable director to continue to serve on the Board.

The Board will act on the GN Committee’s recommendation promptly following its receipt thereof and, in any event, within 90 days of the applicable Shareholders’ meeting. The Board will accept the GN Committee’s recommendation absent exceptional circumstances. If a resignation is accepted, the Board may, subject to applicable law, our Articles and the Investor Rights Agreement, appoint a new director to fill any vacancy created by the resignation, reduce the size of the Board or call a meeting of Shareholders to appoint a replacement. A resignation will be effective upon its acceptance by the Board. We will promptly issue a news release with the Board’s decision. If the Board determines not to accept a resignation, the news release will fully state the reasons for that decision.

OUR APPROACH TO CORPORATE GOVERNANCE

General

We recognize that good corporate governance plays an important role in our overall success and in enhancing shareholder value. The disclosure set out below describes our approach to corporate governance.

The Role of the Board

Our Board is responsible for supervising the management of our business and affairs, including providing guidance and strategic oversight to management. Our Board has adopted a formal mandate in the form set forth in Appendix A that includes the following:

· appointing the President and Chief Executive Officer;

· appointment, evaluation and development of senior management and succession planning;

· approving the corporate goals and objectives that the President and Chief Executive Officer is responsible for meeting and reviewing the performance of the President and Chief Executive Officer against such corporate goals and objectives;

· taking steps to satisfy itself as to the integrity of the President and Chief Executive Officer and other senior executive officers and that the President and Chief Executive Officer and other senior executive officers create a culture of integrity throughout the organization; and

· reviewing and approving management’s strategic and business plans.

14

Our Board has adopted a written position description for the Chair of the Board, which sets out the Chair’s key responsibilities, including, among others, duties relating to setting Board meeting agendas, chairing Board and Shareholder meetings, director development and communicating with Shareholders and regulators. Our Board has also adopted a written position description for our lead director. See “– Meetings of Independent Directors and Conflicts of Interest”.

Our Board has adopted a written position description for each of our committee chairs which sets out each of the committee chair’s key responsibilities, including, among others, duties relating to setting committee meeting agendas, chairing committee meetings and working with the respective committee and management to ensure, to the greatest extent possible, the effective functioning of the committee.

Our Board has adopted a written position description for our President and Chief Executive Officer which sets out the key responsibilities of our President and Chief Executive Officer, including, among other duties in relation to providing overall leadership, ensuring the development of a strategic plan and recommending such plan to our Board for consideration, ensuring the development of an annual corporate plan and budget that supports the strategic plan and recommending such plan to our Board for consideration, supervising day-to-day management and communicating with Shareholders and regulators.

Corporate Governance Policies and Practices

Greenbrook is committed to strong corporate governance policies and practices. Our policies and practices continue to be developed having regard to the external environment and externally cited best practices to ensure that our governance practices are comprehensive, relevant, effective and transparent. We have adopted the following corporate governance policies to date, certain of which are available on our website at www.greenbrooktms.com:

· Code of Conduct;

· Corporate Governance Guidelines;

· Disclosure Policy;

· Insider Trading Policy;

· Majority Voting Policy;

· Clawback Policy; and

· Whistleblower Policy.

Composition of our Board and Board Committees

Under our Articles, our Board is to consist of a minimum of three (3) and a maximum of fifteen (15) directors as determined from time to time by the directors. Our Board currently consists of ten (10) directors, the majority of whom are considered to be independent under applicable securities laws and stock exchange rules. The Board has determined that in furtherance of the Company’s previously-announced restructuring plan, the business of the Company may be properly conducted by a board of directors consisting of eight directors and has, therefore, reduced the size of the Board from ten to eight, effective at the close of the Meeting. Assuming all director nominees are elected to the Board at the Meeting, our Board will consist of eight directors, the majority of whom are considered independent under applicable securities laws and stock exchange rules.

Under the OBCA, a director may be removed with or without cause by a resolution passed by an ordinary majority of the votes cast by our Shareholders present in person or by proxy at a meeting of our Shareholders and who are entitled to vote. The directors will be elected by our Shareholders at each annual meeting of our Shareholders, and all directors will hold office for a term expiring at the close of the next annual meeting or until their respective successors are elected or appointed.

Certain aspects of the composition and functioning of our Board are governed by the terms of the Investor Rights Agreements. See also “Election of Directors”. The nominees for election by our Shareholders as directors will be determined by the Governance and Nominating Committee (the “GN Committee”) in accordance with the provisions of applicable corporate law, the Investor Rights Agreements and the charter of the GN Committee. See also “– Committees of our Board – Governance and Nominating Committee”.

Director Independence

Under National Instrument 58-101 – Disclosure of Corporate Governance Practices, a director is considered to be independent if he or she is independent within the meaning of National Instrument 52-110 – Audit Committees (“NI 52-110”). Pursuant to NI 52-110, an independent director is a director who is free from any direct or indirect relationship which could, in the view of our Board, be reasonably expected to interfere with a director’s independent judgment. Under Nasdaq Rule 5605(a)(2), an independent director is a person other than an executive officer or employee of the company or any other individual having a relationship which, in the opinion of the company’s board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Based on information provided by each director concerning his or her background, employment and affiliations, our Board has determined that, of the eight directors nominated for election to our Board, Bill Leonard, Benjamin Klein and Sasha Cucuz are not considered to be “independent” within the meaning of applicable securities laws and stock exchange rules. Mr. Leonard is considered not independent by reason of the fact that he is our President and Chief Executive Officer. Mr. Klein is considered not independent by reason of the fact that he was formerly our Chief Operating Officer. Mr. Cucuz is considered not independent as a result of the fact that he serves as Executive Chairman of the Company. Certain members of our Board are also members of the board of directors of other public companies (see “Election of Directors – Director Nominee Biographies”). Our Board has not adopted a director interlock policy, but is keeping informed of other public directorships held by its members.

Meetings of Independent Directors and Conflicts of Interest

Our Board believes that given its size and structure, including the fact that a majority of our directors are independent, it is able to facilitate independent judgment in carrying out its responsibilities. To enhance such independent judgment, the independent members of the Board hold in-camera meetings with members of management and the non-independent directors not in attendance, as part of regularly scheduled Board meetings. Open and candid discussion among the independent directors is facilitated by the relatively small size of the Board and great weight is attributed to the views and opinions of the independent directors. Our Board has not appointed an independent Chair; however, assuming Frank Tworecke is elected at the Meeting, Mr. Tworecke will be appointed as lead director by our Board. The lead director is responsible for ensuring that the directors who are independent of management have opportunities to meet without management present, as required. The lead director shall be appointed and replaced from time to time by the Board. Discussions are led by the lead director who provides feedback subsequently to the Chair.

A director who has a material interest in a matter before our Board or any committee on which he or she serves is required to disclose such interest as soon as the director becomes aware of it. In situations where a director has a material interest in a matter to be considered by our Board or any committee on which he or she serves, such director may be required to absent himself or herself from the meeting while discussions and voting with respect to the matter are taking place. Directors are also required to comply with the relevant provisions of the OBCA regarding conflicts of interest.

Committees of our Board

Our Board has established three committees: the Audit Committee, the GN Committee and the Compensation Committee. All members of the Audit Committee, the GN Committee and the Compensation Committee are persons determined by our Board to be independent directors.

Audit Committee

Our Audit Committee consists of three (3) directors, each of whom are persons determined by our Board to be both independent directors and financially literate or sophisticated, each within the meaning of applicable U.S. and Canadian securities laws and/or stock exchange rules. Our Audit Committee is currently comprised of:

· Colleen Campbell (Chair);

· Adrienne Graves; and

· Frank Tworecke.

Each of our Audit Committee members has an understanding of the accounting principles used to prepare financial statements and varied experience as to the general application of such accounting principles, as well as an understanding of the internal controls and procedures necessary for financial reporting. For additional details regarding the relevant education and experience of each member of our Audit Committee, see “Election of Directors – Director Nominee Biographies”.

16

Our Board has adopted a written charter for the Audit Committee that sets out the purpose, composition, authority and responsibility of our Audit Committee, consistent with applicable U.S. and Canadian securities laws and/or stock exchange rules. A copy of the charter of our Audit Committee has been posted on our website at www.greenbrooktms.com. The Audit Committee assists our Board in discharging its oversight of:

· the quality and integrity of our financial statements and related information;

· the independence, qualifications and appointment of our external auditor;

· our disclosure controls and procedures, internal control over financial reporting and management’s responsibility for assessing and reporting on the effectiveness of such controls;

· our risk management processes;

· monitoring and periodically reviewing our whistleblower policy; and

· transactions with our related parties.

Our Audit Committee has access to all of our books, records, facilities and personnel and may request any information about us as it may deem appropriate. It also has the authority, in its sole discretion and at our expense, to retain and set the compensation of outside legal, accounting or other advisors as necessary to assist in the performance of its duties and responsibilities. Our Audit Committee also has direct communication channels with the Chief Financial Officer and our external auditors to discuss and review such issues as our Audit Committee may deem appropriate.

Additional information about our Audit Committee, as required by NI 52-110, is in our Annual Report, which is available on SEDAR at www.sedar.com, and on EDGAR at www.sec.gov.

External Auditor Service Fee

We incurred the following fees by our external auditor, KPMG LLP, during the periods provided below:

	Year Ended December 31, 2022		Year Ended December 31, 2020
Audit Fees(1)	$	914,850	$	1,272,606
Audit-Related Fees(2)	$	161,838	$	123,138
Tax Fees(3)	$	232,525	$	307,959
All Other Fees	$	–	$	–
Total Fees	$	1,309,213	$	1,703,703

Notes:

(1) Consists of fees related to audits of annual financial statements, involvement with registration statements and other filings with various regulatory authorities, quarterly reviews of interim financial statements and consultations related to accounting matters impacting the consolidated financial statements.

(2) Consists primarily of fees related to the acquisitions of Success TMS (Fiscal 2022) and Achieve TMS East, LLC and Achieve TMS Central, LLC (Fiscal 2021).

(3) Consists of fees for tax consultation and compliance services, including indirect taxes.

The written charter of the Audit Committee provides that the Audit Committee must pre-approve the retaining of the auditors for any audit or non-audit service. The pre-approval process involves management presenting the Audit Committee with a description of any proposed non-audit services. The Audit Committee considers the appropriateness of such services and whether the provision of those services would impact the auditor’s independence. The Audit Committee may delegate to one or more members the authority to pre-approve the retaining of the auditors for any non-audit service to the extent permitted by law, but pre-approval by such member or members so delegated must be presented to the full Audit Committee at its first scheduled meeting following such pre-approval.

17

Governance and Nominating Committee

Our GN Committee is comprised of three (3) directors, each of whom has been determined by our Board to be an independent director, and is charged with reviewing, overseeing and evaluating our corporate governance and nominating policies. Our GN Committee is currently comprised of:

· Adrienne Graves (Chair);

· Brian P. Burke; and

· Adele C. Oliva.

Following the Meeting, it is anticipated that our Governance and Nominating Committee will be comprised as follows:

· Adrienne Graves (Chair);

· Brian P. Burke; and

· Frank Tworecke.

No current or proposed member of our GN Committee is an officer of Greenbrook, and as such, our Board believes that the GN Committee is able to conduct its activities in an objective manner.

Our Board believes that the current and proposed members of the GN Committee individually and collectively possess the requisite knowledge, skill and experience in governance matters, including human resource management and general business leadership, to fulfill the GN Committee’s mandate. All current and proposed members of the GN Committee have substantial knowledge and experience as current and former senior executives of large and complex organizations. For additional details regarding the relevant education and experience of each proposed member of our GN Committee, see “Election of Directors – Director Nominee Biographies”.

Our Board has adopted a written charter for the GN Committee that sets forth the purpose, composition, authority and responsibility of our GN Committee. A copy of the written charter of the GN Committee has been posted on our website at www.greenbrooktms.com. Our GN Committee’s purpose is to assist our Board in:

· the recruitment, development and retention of our senior executives;

· maintaining talent management and succession planning systems and processes relating to our senior management;

· developing our corporate governance guidelines and principles and providing us with governance leadership;

· identifying and overseeing the recruitment of candidates qualified to be nominated as members of our Board;

· reviewing the structure, composition and mandate of Board committees; and

· evaluating the performance and effectiveness of our Board and of our Board committees.

Our GN Committee is responsible for establishing and implementing procedures to evaluate the performance and effectiveness of our Board, committees of our Board and the contributions of individual Board members. Our GN Committee also takes reasonable steps to evaluate and assess, on an annual basis, directors’ performance and effectiveness of our Board, committees of our Board, individual Board members, our chair and committee chairs. The assessment addresses, among other things, individual director independence, individual director and overall Board skills, and individual director financial literacy. Our Board receives and considers the recommendations from our GN Committee regarding the results of the evaluation of the performance and effectiveness of our Board, committees of our Board, individual Board members, our chair and committee chairs. In identifying new candidates for our Board, the GN Committee will consider what competencies and skills our Board, as a whole, should possess and assess what competencies and skills each existing director possesses, considering our Board as a group, and the personality and other qualities of each director, as these may ultimately determine the boardroom dynamic. Our GN Committee is also responsible for orientation and continuing education programs for our directors. See also “– Orientation and Continuing Education” below.

18

Compensation Committee

Our Compensation Committee is comprised of three (3) directors, each of whom has been determined by our Board to be an independent director, and is charged with reviewing, overseeing and evaluating our compensation policies. Our Compensation Committee is currently comprised of:

· Brian P. Burke (Chair);

· Robert Higgins; and

· Frank Tworecke.

Following the Meeting, it is anticipated that our Compensation Committee will be comprised as follows:

· Brian P. Burke (Chair);

· Adrienne Graves; and

· Frank Tworecke.

No current or proposed member of our Compensation Committee is an officer of Greenbrook, and as such, our Board believes that the Compensation Committee is able to conduct its activities in an objective manner.

Our Board believes that the current and proposed members of the Compensation Committee individually and collectively possess the requisite knowledge, skill and experience in compensation matters, including human resource management, executive compensation matters and general business leadership, to fulfill the Compensation Committee’s mandate. All current and proposed members of the Compensation Committee have substantial knowledge and experience as current and former senior executives of large and complex organizations. For additional details regarding the relevant education and experience of each proposed member of our Compensation Committee, including the direct experience that is relevant to each committee member’s responsibilities in executive compensation, see “Election of Directors – Director Nominee Biographies”.

Our Board has adopted a written charter for the Compensation Committee that sets forth the purpose, composition, authority and responsibility of our Compensation Committee. A copy of the charter has been posted on our website at www.greenbrooktms.com. Our Compensation Committee’s purpose is to assist our Board in:

· the appointment, performance, evaluation and compensation of our senior executives;

· developing a compensation structure for our senior executives including salaries, annual and long-term incentive plans including plans involving share issuances and other share-based awards;

· establishing policies and procedures designed to identify and mitigate risks associated with our compensation policies and practices;

· assessing the compensation of our directors; and

· developing benefit, retirement and savings plans.

For information on the process by which the Compensation Committee and the Board determine the compensation of our directors and executive officers, see “Director Compensation” and “Executive Compensation” below.

Role of the Compensation Consultant

As part of the Compensation Committee’s annual review of the Company’s compensation program, the Compensation Committee may engage an independent compensation consultant to evaluate the Company’s director and/or executive compensation program against market practice. The Company has not retained a compensation consultant or advisor to assist in determining compensation of any of the Company’s directors or executive officers since the Company’s most recently completed financial year. In late Fiscal 2020 and into Fiscal 2021 (each as defined below), the Company retained Mercer (Canada) Inc. (“Mercer”), an independent compensation consultant, to assist with the development of a director and executive compensation framework for the fiscal year ended December 31, 2021 (“Fiscal 2021”) and beyond. Mercer’s mandate was to provide independent advice to the Compensation Committee on director and executive compensation matters, including identifying a relevant compensation peer group, benchmarking director and executive compensation, reviewing short-term and long-term incentive plan design vehicles and metrics, including compensation risks and governance matters. Mercer provided periodic advice to the Compensation Committee with respect to such compensation matters and in response to other Compensation Committee requests, culminating in the adoption by the Company of a new executive and director compensation framework that became effective for Fiscal 2021 (see “Director Compensation” and “Executive Compensation”). Mercer did not provide any other services to the Company, our directors or management and the Company did not retain any other compensation consultants in 2021 or 2022.

19

The Compensation Committee is of the view that prescriptive formulas and weightings applied to forward-looking objectives cannot capture all aspects of business circumstances and can lead to unintended consequences and potentially foster “narrow-minded” thinking and behaviors. For these reasons, all benchmarking data is used only for informational purposes and the Compensation Committee deliberately avoids the use of a mechanical approach to its compensation analysis. Instead, the Compensation Committee focuses on applying sound judgment in combination with reviewing several sources of information in arriving at compensation decisions

The fees billed by Mercer during the financial years ended December 31, 2022 and 2021 is provided in the table below:

	Year Ended December 31, 2022			Year Ended December 31, 2021
Executive Compensation-Related Fees(1)	$	–	$	61,472
All other fees(2)	$	–	$	4,746
Total fees paid	$	–	$	66,218

Notes:

(1) All fees billed by Mercer in respect of services provided to the Company relating to determining compensation for the Company’s directors and executive officers in 2020 were billed by Mercer in 2021.

(2) Represents the aggregate fees billed for all other services provided by Mercer that are not reported under “Executive Compensation-Related Fees”.

Director Term Limits and Other Mechanisms of Board Renewal

Directors are to be elected at each annual meeting of Shareholders to hold office for a term expiring at the close of the next annual meeting, or until a successor is appointed or elected, and will be eligible for re-election. Nominees will be nominated by the GN Committee, in each case for election by Shareholders as directors in accordance with the provisions of our constating documents and applicable corporate and securities laws. All nominees who are nominated by the GN Committee will be included in the proxy-related materials to be sent to Shareholders prior to each annual meeting of Shareholders.

Our Board has not adopted director term limits or other automatic mechanisms of board renewal. The Company believes such limits and automatic mechanisms would discount the value of experience and unnecessarily deprive the Company of the contribution by directors who have developed a deep knowledge of the Company over time. Rather than adopting formal term limits, mandatory age-related retirement policies and other mechanisms of board renewal, the GN Committee will seek to maintain the composition of our Board in a way that provides, in the judgment of our Board, the best mix of skills and experience to provide for our overall stewardship. Our GN Committee is also expected to conduct a process for the assessment of our Board, each committee and each director regarding his, her or its effectiveness and performance, and to report evaluation results to our Board. See also “– Diversity”.

Orientation and Continuing Education

To maintain reasonable assurance that every new director engages in a comprehensive orientation process and that all directors are provided with continuing education opportunities, the GN Committee has implemented an orientation program for new directors under which a new director will meet with the chair, the lead director, members of senior management and our corporate secretary. New directors will be provided with comprehensive orientation and education as to the nature and operation of the Company and our business, the role of our Board and its committees, and the contribution that an individual director is expected to make. The GN Committee is responsible for overseeing director continuing education designed to maintain or enhance the skills and abilities of the directors and to ensure that their knowledge and understanding of our business remains current. The chair of each committee is responsible for coordinating orientation and continuing director development programs relating to the GN Committee’s mandate.

20

Ethical Business Conduct

We have adopted a written code of conduct (the “Code of Conduct”) that applies to all of our directors, officers and employees. The objective of the Code of Conduct is to provide guidelines for maintaining our and our subsidiaries’ integrity, reputation, honesty, objectivity and impartiality. The Code of Conduct addresses conflicts of interest, protection of our assets, confidentiality, fair dealing with our Shareholders, competitors and employees, insider trading, compliance with laws and reporting any illegal or unethical behavior. As part of the Code of Conduct, any person subject to the Code of Conduct is required to avoid or fully disclose interests or relationships that are harmful or detrimental to our best interests or that may give rise to real, potential or the appearance of conflicts of interest. Our Board has ultimate responsibility for the stewardship of the Code of Conduct and it monitors compliance through the GN Committee. Directors, officers and employees are required to annually certify that they have not violated the Code of Conduct.

The Code of Conduct is available on our website at www.greenbrooktms.com and on SEDAR at www.sedar.com.

Diversity

We believe that having a diverse Board can offer a breadth and depth of perspectives that enhance our Board’s performance. We value diversity of abilities, experience, perspective, education, gender, background, race and national origin. Recommendations concerning director nominees are expected to be based on merit and past performance as well as expected contribution to our Board’s performance and, accordingly, diversity is taken into consideration. As of the date of this Circular, three of ten members on our Board, or 30%, are women. Following the Meeting, assuming all director nominees are elected by Shareholders, two of eight, or 25%, will be women.

We have recruited and selected management candidates that represent a diversity of business understanding, personal attributes, abilities and experience. Currently, 2 of 6 members of our senior management team, or 33%, are female.

The table below provides certain information regarding the diversity of our Board as of the date hereof:

Board Diversity Matrix
Country of Principal Executive Offices	Canada
Foreign Private Issuer	Yes
Disclosure Prohibited under Home Country Law	No
Total Number of Directors	10
	Female	Male	Non- Binary	Did Not Disclose Gender
Part I: Gender Identity
Directors	3	7	0	0
Part II: Demographic Background
Underrepresented Individual in Home Country Jurisdiction	0
LGBTQ+	0
Did Not Disclose Demographic Background	2

We do not currently have a formal policy for the representation and nomination of women on our Board or our management, as we have been successful in recruiting and retaining qualified female directors and management under our existing recruitment policies and processes. We have not adopted formal targets for gender or other diversity representation in part due to the need to consider a balance of criteria for each individual appointment.

21

The composition of our Board and management is shaped by the selection criteria established by the GN Committee. This is achieved by, among other things, ensuring that diversity considerations are taken into account in Board vacancies and management, monitoring the level of female representation on our Board and in management positions, continuing to broaden recruiting efforts to attract and interview qualified female candidates, and committing to retention and training to ensure that our most talented employees are promoted from within our organization.

Disclosure Policy

The Board has adopted a Disclosure Policy to deal with the timely dissemination of all material information (the “Disclosure Policy”). The Disclosure Policy, which will be reviewed annually, establishes consistent guidance for determining what information is material and how it is to be disclosed to avoid selective disclosure and to ensure wide dissemination. The Board, directly and through its committees, reviews and approves the contents of major disclosure documents, including annual and interim consolidated financial statements, prospectuses, the annual information form, management’s discussion and analysis and the management information circular. We seek to communicate to our Shareholders through these documents as well as by means of news releases, our website and investor relations calls and meetings.

Disclosure Committee

A Disclosure Committee comprised of senior management of the Company (the “Disclosure Committee”) oversees the Company’s disclosure process as outlined in the Disclosure Policy. The Disclosure Committee’s mandate includes ensuring that effective controls and procedures are in place to allow the Company to satisfy all of its continuous disclosure obligations, including certification requirements. The Disclosure Committee is also responsible for ensuring that the policies and procedures contained in the Disclosure Policy are in compliance with regulatory requirements. Our Audit Committee is responsible for reviewing our disclosure relating to our financial reporting.

DIRECTOR COMPENSATION

General

The following discussion describes the significant elements of the compensation program for members of the Board and its committees. The compensation of our directors is designed to attract and retain committed and qualified directors and to align their compensation with the long-term interests of our Shareholders. Directors who are employees of the Company (each, an “Excluded Director”) are not entitled to receive any compensation for his or her service as a member of our Board.

Deferred Share Unit Plan for Non-Employee Directors

On May 6, 2021, the Company adopted a deferred share unit plan for non-employee directors (the “DSU Plan”). Each director (other than Excluded Directors) will be required to take at least 50% of their annual retainer (other than annual committee Chair retainers) in deferred share units (“DSUs”) and may elect to take additional amounts in the form of DSUs. Discretionary DSUs may also be granted to non-employee directors under the DSU Plan. Each director wishing to make an election for additional DSUs will be required to elect no later than the end of the calendar year preceding the year in which such election is to apply (and, in the case of a new director, within 30 days after the director’s appointment).

A DSU is a unit, equivalent in value to a Share, credited by means of a bookkeeping entry in the books of the Company, to an account in the name of the director. If and when cash dividends are paid on Shares, additional DSUs will automatically be granted to each director who holds DSUs on the record date for such dividends. Following an eligible director ceasing to hold all positions with the Company, the director will receive a payment in cash at the fair market value of the Shares represented by his or her DSUs generally within ten days of the director’s elected redemption date. Each director’s elected redemption date will not be earlier than the date the director ceases to hold all positions with the Company and will not be later than December 31 of the year following the year in which the director ceases to hold all positions with the Company.

22

Director Fees

Our Board, on the recommendation of the Compensation Committee, is responsible for reviewing and approving any changes to the directors’ compensation arrangements. Working with Mercer during the fiscal year ended December 31, 2020 (“Fiscal 2020”), the Compensation Committee adopted changes to our director compensation framework effective commencing in Fiscal 2021. In particular, Mercer worked with the Compensation Committee to assist it in establishing a framework for director compensation that was in-line with market comparables and with a total director compensation package at target in the range of median compensation for a selected peer group.

In consideration for serving on our Board, each director (other than Excluded Directors) was entitled to be compensated during Fiscal 2022 as indicated below:

Type of Fee		Cash		DSUs(1)
Annual Board Retainer	Chair	$	50,000	$	50,000
	Board Member	$	40,000	$	40,000
Annual Committee Retainer	Audit Committee Chair	$	15,000		Nil
	GN Committee Chair	$	10,000		Nil
	Compensation Committee Chair	$	10,000		Nil
	Audit Committee Membership		Nil		Nil
	GN Committee Membership		Nil		Nil
	Compensation Committee Membership		Nil		Nil
Meeting Fees	Board / Committee Meeting		Nil		Nil

Note:

(1) Directors may elect to receive a higher proportion of their annual board retainer in the form of DSUs, which would result in a decrease to the cash component and a corresponding increase to the DSU component of the applicable directors’ annual board retainer. See “—Deferred Share Unit Plan for Non-Employee Directors” above.

Prior to Fiscal 2021, in lieu of receiving a higher annual cash retainer, each director (other than Excluded Directors) was granted Options under the Equity Incentive Plan (as defined below) each year as follows: 10,000 Options were granted to the Chair; 5,000 Options were granted to each director; and an additional 1,000 Options were granted to each director who was also a Board committee chair. These Options generally vest in three instalments and will generally expire on the tenth anniversary of the grant date. For further details regarding the Equity Incentive Plan, see, “Executive Compensation—Compensation Discussion and Analysis—Long-Term Incentive Plans”.

All directors are also entitled to be reimbursed for their reasonable out-of-pocket expenses incurred while serving as directors.

Directors’ Hedging Policy

Our insider trading policy prohibits all of our directors from selling “short” or selling “call options” on any of our securities and from purchasing financial instruments, such as prepaid variable forward contracts, equity swaps, collars or units of exchange funds that are designed to hedge or offset a decrease in the market value of equity securities granted to such directors as compensation or of any other securities of Greenbrook held directly or indirectly by such person.

23

The value of the DSUs is calculated based on the closing price of the Shares on the TSX on the applicable vesting date.

EXECUTIVE COMPENSATION

Introduction

The following discussion describes the significant elements of the compensation program for the named executive officers (“named executive officers” or “NEOs”) of the Company, namely:

· Bill Leonard, President and Chief Executive Officer;

· Erns Loubser, Chief Financial Officer and Treasurer;

· Geoffrey Grammer, Chief Medical Officer;

· Diana Shi, Former Senior Vice President of Operations, and

· Euphia Smith, Former Chief Marketing Officer.

Compensation Discussion and Analysis

Overview

We operate in a highly competitive and evolving market. To succeed in this market and achieve our strategic business and financial objectives, we need to attract, retain and motivate a highly talented executive team. Our executive compensation program is designed to achieve the following objectives:

· provide compensation opportunities in order to attract and retain talented, high-performing and experienced executive officers, whose knowledge, skills and performance are critical to our success;

· motivate our executive team to achieve our strategic business and financial objectives;

· align the interests of our executive officers with those of our Shareholders; and

· provide incentives that encourage appropriate levels of risk-taking by our executive team.

25

We offer our executive officers cash compensation in the form of base salary and a discretionary annual bonus, and occasionally equity-based compensation in the form of Options, PSUs and restricted share units (“RSUs” and, collectively with the PSUs, “Share-Based Awards” and, collectively with Options, “Awards”) under the Equity Incentive Plan (as defined below). We believe that executives who have significant equity investment in the Company, whether in the form of Shares or equity-based compensation awards, will be motivated to achieve our strategic business and financial objectives, and it also aligns their interests with the long-term interests of our Shareholders.

While we have determined that our current executive officer compensation program is effective at attracting and maintaining executive officer talent, we evaluate our compensation philosophy and compensation program on an ongoing basis and plan to continue to review the compensation of our executive team on an annual basis to ensure that we are providing competitive compensation opportunities for our executive team and that the interests of our executives are in line with the long-term interests of our Shareholders. As part of this review process, we expect to be guided by the philosophy and objectives outlined above, as well as other factors which may become relevant.

Compensation-Setting Process

Prior to April 22, 2021, the Board had established two committees: the Audit Committee and the Governance, Compensation and Nominating Committee. On April 22, 2021, the Board determined that it was in the best interests of the Company to split the responsibilities of the GCN Committee into a separate and distinct Governance and Nominating Committee and a separate and distinct Compensation Committee. Accordingly, our Board has three committees: the Audit Committee, the GN Committee and the Compensation Committee. All current and proposed members of the Audit Committee, the GN Committee and the Compensation Committee are persons determined by our Board to be independent directors.

The Compensation Committee is responsible for assisting our Board in fulfilling its governance and supervisory responsibilities, and overseeing our human resources, succession planning, and compensation policies, processes and practices. The Compensation Committee is also responsible for ensuring that our compensation policies and practices provide an appropriate balance of risk and reward consistent with our risk profile.

Our Board has adopted a written charter for the Compensation Committee setting out its responsibilities for administering our compensation programs and reviewing and making recommendations to our Board concerning the level and nature of the compensation payable to our directors and executive officers. The Compensation Committee’s oversight includes reviewing objectives, evaluating performance and ensuring that total compensation paid to our executive officers, personnel who report directly to our President and Chief Executive Officer and various other key employees is fair, reasonable and consistent with the objectives and philosophy of our compensation program. See also “Our Approach to Corporate Governance – Committees of our Board – Compensation Committee”.

Our President and Chief Executive Officer makes recommendations to the Compensation Committee each year with respect to the compensation for the other NEOs.

The Compensation Committee generally meets annually to review the compensation program and make recommendations for any changes to the Board, as appropriate. As part of this annual review, the Compensation Committee may engage an independent compensation consultant to evaluate the Company’s executive compensation program against market practice.

For example, working with Mercer in late Fiscal 2020, the Compensation Committee adopted certain changes to our executive compensation structure, effective for Fiscal 2021. In particular, Mercer worked with the Compensation Committee to assist it in establishing a framework for executive officer compensation that was in-line with market comparables and with a total direct compensation package (that is, base salary and incentive compensation) at target in the range of median compensation for a selected peer group. For those purposes, the Compensation Committee selected a peer group from relevant industries in North America, including from the healthcare services, healthcare facilities and healthcare equipment sectors, and then narrowed the resultant list based on quantitative and qualitative factors. Those factors included whether a company is based in the United States or has primary operations in the United States and the relative size of the company compared to Greenbrook. The final peer group used for assessing compensation levels (the “Compensation Peer Group”) is comprised of the following 11 entities:

Compensation Peer Group
Star Equity Holdings, Inc.	Novation Companies, Inc.
CRH Medical Corporation	Neuronetics, Inc.
Enzo Biochem, Inc.	Sunlink Health Systems, Inc.
Protech Home Medical Corp.	BrainsWay Ltd.
OnTrack, Inc.	IMAC Holdings, Inc.
The Joint Corp.

See “Our Approach to Corporate Governance – Role of the Compensation Consultant”.

Risk and Executive Compensation

In reviewing our compensation policies and practices each year, the Compensation Committee seeks to ensure the executive compensation program provides an appropriate balance of risk and reward consistent with the risk profile of the Company. The Compensation Committee also seeks to ensure the Company’s compensation practices do not encourage excessive risk-taking behavior by the executive team.

Governance Policies

Trading Restrictions

All of our executive officers (including the NEOs), directors and employees are subject to our insider trading policy, which prohibits trading in our securities while in possession of material undisclosed information about the Company. Under this policy, such individuals are also prohibited from entering into certain types of hedging transactions involving the securities of the Company, such as short sales, puts and calls. Furthermore, we permit our executive officers, including the NEOs, to trade in the Company’s securities, including the exercise of Awards, only during prescribed trading windows.

Clawback Policy

We have a clawback policy which applies to annual bonus payments and other incentive compensation provided to current and former executive officers, including the NEOs.

The Board has defined a number of reasons for which it may pursue a clawback of an executive officer’s annual bonuses and other incentive awards. Under our clawback policy, a clawback may be triggered if an executive officer:

· engages in misconduct that results in the need to restate our financial statements, where the individual received an award calculated on the achievement of those financial statements and the award received would have been lower had the financial statements been properly reported;

· commits a material breach of our Code of Conduct;

· engages in gross negligence, fraud, theft, dishonesty or willful misconduct; or

· is convicted of or pleads guilty or nolo contendere to a criminal offence or a statutory offence involving moral turpitude.

The clawback policy provides that the Board may require an executive officer to repay all or a portion of the annual bonus payments and other incentive compensation received over a specified period preceding the triggering event, among other remedies available to the Board. The GN Committee will continue to keep this policy under review as part of its regular risk review.

We intend to update our current clawback policy once the Nasdaq finalizes its proposed listing standards in accordance with Rule 10D-1 under the U.S. Securities Exchange Act of 1934, as amended.

Components of Compensation

The compensation of our executive officers includes two major elements: (i) base salary, and (ii) a discretionary annual bonus. Additionally, from time to time, the Board has granted awards to executives who have taken on additional responsibilities and/or as a way to periodically recognize executives who have consistently performed at an exceptional level. These awards are in the form of Options, RSUs and/or PSUs under the Equity Incentive Plan, which assist the Company in retaining key employees who have the potential to add value to the Company over the longer term. Perquisites and benefits are not a significant element of compensation of our executive officers.

27

Base Salaries

Base salary is provided as a fixed source of compensation for our executive officers. Base salaries are determined on an individual basis taking into account the scope of the executive officer’s responsibilities and their prior experience. Base salaries are reviewed annually by the Board and may be increased based on the executive officer’s success in meeting or exceeding individual objectives, as well as to maintain market competitiveness. In addition, base salaries can be adjusted as warranted throughout the year to reflect promotions or other changes in the scope or breadth of an executive officer’s role or responsibilities.

Discretionary Annual Bonuses

The Board believes that its ability to exercise discretion and judgment is critical to ensuring that annual bonuses reflect the assessment of risk in the decisions and actions taken by our executive team and consider unexpected circumstances or events that have occurred during the year. In determining annual bonus amounts, the Board reviews each NEO’s performance over the year, including how their decisions and actions align with the Company’s long-term strategy and how they considered the risks associated with such decisions, along with the Company’s performance over the year. The discretionary annual bonus, if any, typically represents less than 50% of an NEO’s total compensation. No NEOs have a contractual right to a bonus in respect of Fiscal 2022. No annual bonuses were awarded to any of the NEOs in Fiscal 2022. See “— Summary Compensation Table”.

Long-Term Incentive Plans

Amended and Restated Omnibus Equity Incentive Plan

In 2018, we established the stock option plan of the Company, which was amended and restated by our Board on May 24, 2019 (and approved by Shareholders on June 28, 2019) (as amended and restated, the “Stock Option Plan”).

In 2021, the Stock Option Plan was further amended and restated by our Board on May 6, 2021 (and approved by our Shareholders on June 14, 2021) and is now referred to as the Amended and Restated Omnibus Equity Incentive Plan (the “Equity Incentive Plan”). The amendments were made by our Board to (a) permit the grant of Share-Based Awards under the Equity Incentive Plan, (b) set limitations on employee post-employment entitlements that might arise pursuant to statute or the common law, (c) update the non-employee director participation limits to account for RSUs and PSUs, (d) update the amendment provisions that do not require Shareholder approval to account for RSUs and PSUs, (e) update the amendment provisions that do require Shareholder approval to account for RSUs and PSUs and to meet the requirements of the TSX, (f) include a clawback provision (as described below), (g) qualify for favorable treatment under applicable tax laws, and (h) make other changes of a housekeeping nature. The Equity Incentive Plan, as amended and restated on May 6, 2021, applies to all Awards granted on or after May 6, 2021. No changes were made to the Equity Incentive Plan in Fiscal 2022.

The Equity Incentive Plan provides eligible participants with compensation opportunities that enhance our ability to attract and retain our executive officers, other key employees, directors and consultants and ensure that their interests are aligned with the success of the Company and its affiliates. The material features of the Equity Incentive Plan are summarized below.

Administration and Eligibility

The Equity Incentive Plan is administered by our Board, provided that the Board may, in its discretion, delegate its administrative powers under the Equity Incentive Plan to the Compensation Committee. Pursuant to the terms of the Equity Incentive Plan, the Board is empowered to (a) interpret and administer the plan from time to time, (b) adopt, amend and rescind rules and regulations for carrying out the Equity Incentive Plan, (c) grant Awards, (d) determine the exercise price, performance period, performance vesting conditions, vesting schedule, term, limitations, restrictions and conditions applicable to Awards, (e) waive or amend the performance vesting conditions, any other vesting conditions or vesting schedule, and (f) make any other determinations that the Board deems necessary or desirable for the administration of the Equity Incentive Plan.

Employees, directors and consultants of the Company and its affiliates are eligible to participate in the Equity Incentive Plan; however, directors are not entitled to receive grants of PSUs.

28

Shares Subject to the Equity Incentive Plan and Participation Limits

The maximum number of Shares that are available for issuance under the Equity Incentive Plan (including upon the exercise of the replacement options that were granted by the Company in exchange for options granted under our predecessor’s amended and restated stock option plan) is 10% of the issued and outstanding Shares from time to time; provided that, the maximum number of Shares that may be issued pursuant to RSUs and PSUs shall not exceed 5% of the number of issued and outstanding Shares from time to time. Shares underlying Options and replacement Options that have been exercised or that have expired or terminated for any reason and Shares underlying Share-Based Awards that have been settled or disposed of or that have expired or been terminated for any reason will become available for subsequent issuance under the Equity Incentive Plan.

As at December 31, 2022, 803,314 Awards have been granted under the Equity Incentive Plan, representing approximately 2.7% of the issued and outstanding Shares as of that date. As of December 31, 2022, 2,140,340 Awards remain available for future issuance under the Equity Incentive Plan, representing approximately 7.3% of the issued and outstanding Shares as of December 31, 2022.

The number of Shares that may be (i) issued to insiders of the Company within any one-year period, or (ii) issuable to insiders of the Company at any time, in each case, under the Equity Incentive Plan alone, or when combined with all of the Company’s other security-based compensation arrangements, cannot exceed 10% of the outstanding Shares. Additionally, the aggregate value of all Awards granted to any one director in any one-year period under all security-based compensation arrangements of the Company may not exceed C$150,000 (with no more than C$100,000 attributable to Options) based on the grant date fair value of the Awards, other than Awards granted in lieu of cash fees payable for serving as a director.

Options

The terms and conditions of grants of Options, including the quantity, grant date, exercise price, vesting conditions and other terms and conditions will be set out in the participant’s grant agreement. The exercise price for Options will be determined by our Board, which may not be less than the fair market value of a Share (being the closing price of a Share on the TSX for Canadian resident participants or on the Nasdaq for U.S. resident participants on the applicable date (the “Fair Market Value”)) on the date the Option is granted. Options will vest in accordance with the vesting schedule established on the grant date, which historically has been as to one-third on each of the first three anniversaries of the grant date.

Options must be exercised within a period fixed by our Board that may not exceed ten years from the date of grant, provided that if the expiry date falls during a blackout period, the expiry date will be automatically extended until ten business days after the end of the blackout period. The Equity Incentive Plan also provides for earlier expiration of Options upon the occurrence of certain events, including the termination of a participant’s employment.

In order to facilitate the payment of the exercise price of the Options, the Equity Incentive Plan contains a cashless exercise feature and a net settlement feature. Additionally, vested Options can be exercised by payment in full of the applicable exercise price in cash or by certified check, bank draft or money order payable to the Company or by such other means as might be specified from time to time by the Board. Pursuant to the net settlement feature, to the extent permitted by the Board and as permitted by applicable law, a participant may elect to have the Company retain such number of Shares otherwise issuable in connection with the exercise of the Option as will have a Fair Market Value on the date of such exercise equal to the aggregate exercise price. Pursuant to the cashless exercise feature, to the extent permitted by the Board and as permitted by applicable law, a participant may elect to receive (i) an amount in cash equal to the cash proceeds realized upon the sale of the Shares underlying the Options by a securities dealer in the capital markets, minus the aggregate exercise price, any applicable withholding taxes and any transfer costs charged by the securities dealer, (ii) an aggregate number of Shares that is equal to the number of Shares underlying the unexercised Options, minus the number of Shares sold by a securities dealer in the capital markets as required to realize cash proceeds equal to the aggregate exercise price, any applicable withholding taxes and any transfer costs charged by the securities dealer, or (iii) a combination of clauses (i) and (ii).

RSUs and PSUs

The terms and conditions of grants of RSUs and PSUs, including the quantity, type of award, grant date, vesting conditions, vesting periods, settlement date and other terms and conditions with respect to the awards, will be set out in the participant’s grant agreement.

29

In the case of PSUs, the performance-related vesting conditions may include financial or operational performance of the Company, total shareholder return (either absolute or relative or both), individual performance criteria or other criteria as determined by our Board, which will be measured over a specified period, generally until the end of the third calendar year from the date of the grant.

Subject to the achievement of the applicable vesting and performance-related (if applicable) conditions, on the settlement date of an RSU or PSU, the Company will either, in its sole discretion (i) issue from treasury the number of Shares covered by the RSUs or PSUs and related Dividend Share Units (as defined below), or (ii) deliver to the participant an amount in cash (net of applicable withholding taxes) equal to the number of Shares covered by the RSUs or PSUs and related Dividend Share Units multiplied by the Fair Market Value as at the settlement date, or (iii) a combination of (i) and (ii). Notwithstanding the ability for the Company to settle vested RSUs (and related Dividend Share Units) in Shares pursuant to subsection (i) or through a cash payment pursuant to subsection (ii) above, vested RSUs held by directors who are Canadian taxpayers will be settled in Shares pursuant to subsection (i); provided that, the Company may, in its sole discretion, permit such a director to elect to receive a cash payment pursuant to subsection (ii).

Dividend Share Units

When dividends (other than stock dividends) are paid on Shares, additional share units (“Dividend Share Units”) will be automatically credited to each participant who holds RSUs or PSUs on the record date for such dividends. The number of Dividend Share Units to be credited to a participant is equal to the aggregate number of RSUs and PSUs held by the participant on the relevant record date multiplied by the amount of the dividend paid by the Company on each Share, and then divided by the Fair Market Value of the Shares on the dividend payment date. Dividend Share Units shall be in the form of RSUs or PSUs, as applicable. Dividend Share Units credited to a participant will be subject to the same vesting conditions applicable to the related RSUs or PSUs.

Cessation of Employment or Services

Unless otherwise determined by our Board or if a participant’s employment agreement or consulting agreement or arrangement expressly provides more favorable rights with respect to the Awards, in the event of a cessation of employment or services, the following rights apply.

In the event a participant ceases to be an employee, director or consultant of the Company or a designated affiliate, all outstanding Awards granted to the participant under the Equity Incentive Plan that are unvested on the cessation date will be forfeited. All outstanding Options that have vested as of the cessation date will be exercisable as follows, after which time such vested Options will automatically terminate: (i) if the participant ceases to be an employee, director or an individual consultant by reason of death or disability, the participant’s Options must be exercised within 9 months of the date of death or disability; (ii) if the participant ceases to be an employee, director or consultant (whether an individual or entity) by reason of termination without cause, the participant’s Options must be exercised within 3 months of the cessation date; (iii) if the participant ceases to be an employee, director or consultant (whether an individual or entity) by reason of voluntary resignation or termination, the participant’s Options must be exercised within 30 days of the cessation date; and (iv) if the participant ceases to be an employee, director or consultant (whether an individual or entity) by reason of termination for cause, the participant’s Options will automatically terminate on the cessation date and may no longer be exercised. In no event may Options be exercised later than the applicable expiry date of the Options, after which time all remaining Options will terminate. Any vested Share-Based Awards held by the participant will be settled as soon as practicable following the cessation date.

In the event a participant ceases to be an employee, director or consultant of the Company or a designated affiliate due to a termination for cause, all Awards (whether vested or unvested) will be forfeited on the cessation date.

30

Change of Control

In the event of a change in control, except as otherwise provided in a grant agreement, the Board will provide for the treatment of each outstanding Award, which treatment need not be uniform for all participants and/or Awards and which may include, without limitation, one or more of the following: (i) (a) continuation of such Award, or (b) conversion of such Award into, or substitution or replacement of such Award with, an award with respect to equity interests of the successor (or a parent or subsidiary thereof) with substantially equivalent terms and value as such Award; (ii) acceleration of the vesting and/or exercisability of Awards; (iii) upon written notice, providing that outstanding Options must be exercised, to the extent then exercisable, during a specified period of time preceding the change in control as determined by the Board, and further providing for the right to exercise an Option as of immediately, or during a specified period, prior to such change in control, and the termination and forfeiture of any such Option without payment of any consideration therefor to the extent such Option is not timely exercised; (iv) if vesting of such Award is subject to performance criteria, the level of attainment of such criteria shall be determined by the Board in its discretion, including, without limitation, by deeming such criteria attained at the applicable target or maximum level regardless of actual performance, or measuring the attainment of such criteria based on actual performance through such change in control or a specified date prior thereto; (v) other than for participants who are Canadian taxpayers in respect of their Options, automatic cancellation or voluntary surrender of all or any portion of outstanding Awards for payment of their fair value (in the form of cash, securities, rights and/or other property) as determined in the sole discretion of the Board; (vi) permitting an Option to be surrendered to the Company in consideration for a payment, in cash, securities, rights and/or other property, in an amount equal to the intrinsic value of such Option as of immediately prior to such change in control; and/or (vii) cancellation of all or any portion of outstanding unvested and/or unexercisable Awards for no consideration.

Adjustments

In the event that there is any change in the Shares or in the capital structure of the Company by reason of any stock or extraordinary cash dividend, stock split, reverse stock split, an extraordinary corporate transaction such as any recapitalization, reorganization, merger, consolidation, combination, exchange or other relevant change in capitalization (each an “Adjustment Event”), then the Board, to prevent inappropriate dilution or enlargement of participants’ rights under the Equity Incentive Plan, will substitute or adjust, in its sole discretion: (i) the number and kind of shares or other securities that may be granted pursuant to Awards; (ii) the number and kind of shares or other securities subject to outstanding Awards; (iii) the exercise price applicable to outstanding Options; (iv) the number of Share-Based Awards held by the participants; (v) the vesting of PSUs; and/or (vi) other value determinations (including performance conditions) applicable to the Equity Incentive Plan or outstanding Awards; provided, however, that no adjustment will obligate the Company to issue or sell fractional securities.

Clawback

The Equity Incentive Plan provides that any Award which is subject to recovery or recoupment under applicable laws, stock exchange listing requirements or policies adopted by the Company, as may be adopted and amended from time to time, will be subject to such deductions and clawbacks as may be required pursuant to such laws, stock exchange listing requirements or policies.

Amendment or Termination

Our Board may amend or suspend any provision of the Equity Incentive Plan or any Award, or terminate the Equity Incentive Plan, at any time without approval of shareholders, subject to those provisions of applicable law and the rules, regulations and policies of the Nasdaq, if any, that require the approval of shareholders or any governmental or regulatory body. However, except as set forth in the Equity Incentive Plan or as required pursuant to applicable law or to qualify for any intended tax treatment, no action of the Board or shareholders may materially adversely alter or impair the rights of a participant under any Award previously granted to the participant without the consent of the affected participant.

Our Board is permitted to make certain amendments to the Equity Incentive Plan or to any Award outstanding thereunder without seeking shareholder approval, including but not limited to, housekeeping amendments or amendments of an administrative nature, amendments to comply with applicable law or stock exchange rules, amendments necessary for Awards to qualify for favorable treatment under applicable tax laws, amendments to the vesting provisions of the plan or any Award, amendments to include or modify a cashless exercise feature, amendments to the termination or early termination provisions of the Equity Incentive Plan or any Award, and amendments necessary to suspend or terminate the Equity Incentive Plan. However, only the following types of amendments will not be able to be made without obtaining shareholder approval:

· increasing the number of Shares reserved for issuance under the Equity Incentive Plan;

· increasing the length of the period after a blackout period during which Options may be exercised;

31

· any amendment that would result in the exercise price for any Option being lower than the Fair Market Value on the applicable date of grant;

· permitting the introduction or reintroduction of non-employee directors as eligible recipients of Awards on a discretionary basis or increasing the limits previously imposed on non-employee director participation;

· removing or exceeding the insider participation limit;

· reducing the exercise price of an Option or allowing for the cancellation and reissuance of an Option, which would be considered a repricing, in each case, except pursuant to a change of control or an Adjustment Event;

· extending the expiry date of an Option, except for an automatic extension of an Option that expires during a blackout period;

· permitting awards to be transferred or assigned other than for normal estate settlement purposes;

· amending the amendment provision under the Equity Incentive Plan which has the effect of deleting or reducing the range of amendments which required shareholder approval; or

· amendments required to be approved by shareholders under applicable law or the rules, regulations and policies of the Nasdaq, as applicable.

Assignment

Except as required by law or in the event of death or disability of the participant, the rights of a participant under the Equity Incentive Plan are not transferable or assignable.

Burn Rate

The following table provides the number of Awards granted under the Equity Incentive Plan for Fiscal 2022, Fiscal 2021 and Fiscal 2020, expressed as a percentage of the weighted average number of Shares outstanding during the applicable fiscal year (“Burn Rate”). All figures in the below table are shown on a post-Share Consolidation basis.

Fiscal Year	Number of Awards Granted	Weighted Average Number of Shares Outstanding	Burn Rate
Fiscal 2022	–	23,235,655	–	%
Fiscal 2021	225,147	15,423,870	1.46	%
Fiscal 2020	159,500	12,799,876	1.25	%

Benefit Plans

We provide some of our executive officers with disability, health and dental insurance programs on a comparable basis as other employees of the Company. We offer these benefits consistent with local market practice.

Perquisites

We do not offer significant perquisites as part of our compensation program.

Pension Plan Benefits

Dr. Grammer participates in, and prior to their departures from the Company in 2022, Ms. Shi and Ms. Smith participated in, the Company’s 401(k) plan made available to its U.S. employees. The Company provides an employer safe harbor matching contribution equal to 100% of a participant’s salary deferrals under the plan up to the first 1% of plan eligible compensation, plus 50% of a participant’s salary deferrals under the plan up to the next 5% of plan eligible compensation, subject to the limits imposed by the Internal Revenue Service. Other than the 401(k) plan, the Company does not have any pension plans that provide for payments of benefits at, following or in connection with, retirement or provide for retirement or deferred compensation plans for the NEOs or directors.

Termination and Change of Control Benefits

For a summary of the termination and change of control benefits provided under the Equity Incentive Plan, please refer to “– Components of Compensation – Long-Term Incentives”. Except as described below, the Company has not entered into contractual termination, post-termination or change of control arrangements with any of its NEOs.

TMS NeuroHealth Centers Services, LLC, a subsidiary of the Company (“TMS Services US”), has entered into an employment agreement with Mr. Leonard that provides for contractual termination entitlements. In connection with Mr. Leonard’s termination by TMS Services US on a without cause basis or his resignation with good reason, Mr. Leonard is entitled to his accrued base salary and paid time off through the termination date, a pro-rated annual bonus payment based on his service to the termination date, and subject to Mr. Leonard’s execution of a general release of claims in favor of TMS Services US and its affiliates, continued payment of his base salary for a period of 18 months following the termination date. If Mr. Leonard was terminated on a without cause basis or resigned with good reason on December 31, 2022, he would have been entitled to his accrued base salary, paid time off and annual bonus and a severance payment equal to US$712,500. Mr. Leonard would not have received any incremental payments or benefits in respect of his Awards outstanding under the Equity Incentive Plan in connection with such events.

Mr. Leonard is subject to a customary confidentiality covenant and certain restrictive covenants that will continue to apply following the termination of his employment, including non-competition and non-solicitation provisions which are in effect during Mr. Leonard’s employment and for eighteen months thereafter.

Ms. Smith departed Greenbrook effective December 2022. In connection with her departure, Ms. Smith received a severance payment in the amount of $137,958. The Company paid $17,000 of Ms. Smith’s severance payment and the balance was paid by the Company’s insurance provider. Ms. Smith was not entitled to receive any incremental payments or benefits in respect of her Awards outstanding under the Equity Incentive Plan in connection with her departure.

Ms. Smith’s employment agreement and settlement relating to her departure contained customary confidentiality covenant and certain restrictive covenants that will continue to apply following her departure, including non-competition and non-solicitation provisions which are in effect for the two years following Ms. Smith’s departure.

Performance Graph

The following graph compares the Company’s cumulative total shareholder return to the S&P/TSX Composite Total Return Index and the S&P/TSX Capped Healthcare Total Return Index, assuming reinvestment of any dividends and considering a $100 investment on October 3, 2018, being the date the Company’s Shares began trading on the TSX. The S&P/TSX Composite Total Return Index tracks the share prices of the largest companies on the TSX measured by market capitalization. Stocks included in this index cover all sectors of the economy and are not significantly weighted in the any comparable industry to the Company and are therefore not directly comparable to Greenbrook. The information contained in the graph relating to the period from October 3, 2018 to February 4, 2021 (inclusive) has been adjusted to give effect to the Share Consolidation. The Common Shares are currently only traded on the Nasdaq (symbol: GBNH) as the Company delisted from the TSX effective March 13, 2023.

33

Cumulative Total Shareholder Return
October 3, 2018 to December 31, 2022

During the period covered by the performance graph, our common shares have underperformed the S&P/TSX Composite Total Return Index and have both outperformed and underperformed the S&P/TSX Capped Healthcare Total Return Index. However, throughout Fiscal 2022, our common shares largely underperformed both the S&P/TSX Composite Total Return Index and the S&P/TSX Capped Healthcare Total Return Index.

Executive officer compensation is not strongly correlated to Shareholder returns in the short term, in part because equity-based incentives are calculated at the time of grant using grant date fair values, which do not reflect the actual value of compensation received when such incentives vest or are settled. In the longer term, executive officer compensation is directly impacted by the Company’s Share price performance.

Fiscal 2022 represented our fourth full fiscal year as a public company. As such, there is limited history of our common shares trading on the TSX and/or the Nasdaq, and it may not be possible to draw conclusions from the existing trends. Aside from base salaries, our compensation program is designed to include short-term incentives that align with the near-term targets of the business as well as long-term incentives that are tied to successful execution against our long-term growth strategy.

Appendix A
MANDATE OF THE BOARD OF DIRECTORS

1. Introduction

The members of the board of directors (respectively, the “Directors” and the “Board”) of Greenbrook TMS Inc. (the “Company”) are elected by the shareholders of the Company and are responsible for the stewardship of the Company. The purpose of this mandate (the “Board Mandate”) is to describe the principal duties and responsibilities of the Board, as well as some of the policies and procedures that apply to the Board in discharging its duties and responsibilities.

Certain aspects of the composition and organization of the Board are prescribed and/or governed by the Business Corporations Act (Ontario) and the constating documents of the Company.

2. Chair of the Board

The Board will appoint an independent director to act as Chair of the Board (the “Chair”). If the Board determines that this is not appropriate in the circumstances and instead appoints a non-independent director to act as Chair of the Board, the Board will also appoint an independent director to act as lead director (the “Lead Director”). Either an independent Chair of the Board or the Lead Director will act as the effective leader of the Board and ensure that the Board’s agenda will enable it to successfully carry out its duties. The Chair of the Board and the Lead Director, as applicable, may be removed at any time at the discretion of the Board.

3. Board Size

The constating documents of the Company provide that the Board shall be comprised of a minimum of three (3) Directors and a maximum of fifteen (15) Directors. The Board shall periodically review its size in light of its duties and responsibilities from time to time. Applicable residency requirements will be complied with in respect of the composition of the Board.

5. Role and Responsibilities of the Board

The Board is responsible for supervising the management of the business and affairs of the Company and is expected to focus on guidance and strategic oversight with a view to increasing shareholder value.

In accordance with the Business Corporations Act (Ontario), in discharging his or her duties, each Director must act honestly and in good faith, with a view to the best interests of the Company. Each Director must also exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

6. Board Meetings

(a) In accordance with the constating documents of the Company, meetings of the Board may be held at such times and places as the Chair may determine and as many times per year as necessary to effectively carry out the Board’s responsibilities.

The independent Directors shall have regularly scheduled meetings, at least twice annually, without senior executives of the Company and any non-independent Directors.

The Board will, however, retain its oversight function and ultimate responsibility for such matters and associated delegated responsibilities.

8. Strategic Planning Process and Risk Management

(a) The Board shall adopt a strategic planning process to establish objectives and goals for the Company’s business and shall review, approve and modify as appropriate the strategies proposed by senior executives to achieve such objectives and goals. The Board shall review and approve, at least on an annual basis, a strategic plan which takes into account, among other things, the opportunities and risks of the Company’s business and affairs.

(b) The Board, in conjunction with management, shall be responsible to identify the principal risks of the Company’s business and oversee management’s implementation of appropriate systems to seek to effectively monitor, manage and mitigate the impact of such risks. Pursuant to its duty to oversee the implementation of effective risk management policies and procedures, the Board may delegate to applicable Board committees the responsibility for assessing and implementing appropriate policies and procedures to address specified risks, including delegation of financial and related risk management to the Audit Committee and delegation of risks associated with compensation policies and practices to the Governance, Compensation and Nominating Committee.

9. Succession Planning, Appointment and Supervision of Senior Executives

(a) The Board shall approve the corporate goals and objectives of the CEO and review the performance of the CEO against such corporate goals and objectives. The Board shall take steps to satisfy itself as to the integrity of the CEO and other senior executives of the Company and that the CEO and other senior executives create a culture of integrity throughout the organization.

(b) The Board shall approve the succession plan for the Company, including the selection, appointment, supervision and evaluation of the senior executives of the Company, and shall also approve the compensation of the senior executives of the Company upon recommendation of the Governance, Compensation and Nominating Committee.

The Board shall approve applicable regulatory filings that require or are advisable for the Board to approve, which the Board may delegate in accordance with Section 7(b) of this mandate. These include, but are not limited to, the annual audited financial statements, interim financial statements and related management’s discussion and analysis accompanying such financial statements, earnings press releases, management proxy circulars, annual information forms and annual reports, prospectuses and offering documents and other applicable disclosure.

12. Corporate Disclosure and Communications

The Board will seek to ensure that corporate disclosure of the Company complies with all applicable laws, rules and regulations and the rules and regulations of the stock exchanges upon which the Company’s securities are listed. In addition, the Board shall adopt appropriate procedures designed to permit the Board to receive feedback from shareholders on material issues.

13. Corporate Policies

14. Review of Mandate
