(a) Solely to the extent any such information has not been provided to Neuronetics by Greenbrook, the Shareholder shall as soon as practicable, and in any event, within 24 hours, notify Neuronetics (orally at first and then in writing, in each case within 24 hours) if it receives or otherwise becomes aware of any inquiry, proposal or offer that constitutes or would reasonably be expected to constitute or lead to a Greenbrook Acquisition Proposal, or any request for copies of, access to, or disclosure of, confidential information relating to Greenbrook or any of its Subsidiaries in relation to a possible Greenbrook Acquisition Proposal, of such Greenbrook Acquisition Proposal, inquiry, proposal, offer or request, including the identity of the Person making such Greenbrook Acquisition Proposal, inquiry, proposal, offer or request and the material terms and conditions thereof and copies of all material or substantive documents or correspondence received in respect of, from or on behalf of any such Person.

(ii) the Shareholder has been, and continues to be, in material compliance with this Section 3.2(c).

(c) Notwithstanding anything to the contrary contained herein, the Shareholder may terminate this Agreement if all of the following conditions are satisfied:

(i) the Shareholder in good faith has determined that the Greenbrook Acquisition Proposal constitutes a Greenbrook Enhanced Superior Proposal;

(ii) the Greenbrook Shareholder Approval has not been obtained;

(iii) the Shareholder has been, and continues to be, in material compliance with this Section 3.2;

(iv) the Shareholder has promptly provided Neuronetics with a notice in writing that there is a Greenbrook Enhanced Superior Proposal, together with all documentation related to and detailing the Greenbrook Enhanced Superior Proposal, including a copy of any proposed agreement and all ancillary documentation relating to such Greenbrook Enhanced Superior Proposal as well as the cash value that the Shareholder has determined in good faith should be ascribed to any non-cash consideration offered under the Greenbrook Enhanced Superior Proposal; and

(v) prior to or concurrent with such termination, Greenbrook terminates the Arrangement Agreement pursuant to Section 7.2(a)(iv)(E) of the Arrangement Agreement and pays the Greenbrook Termination Fee in accordance with Section 7.3(b)(ii) of the Arrangement Agreement.

4.1 Termination

This Agreement will terminate upon the earliest to occur of:

(a) the mutual agreement in writing of the Shareholder and Neuronetics;

(b) written notice by the Shareholder to Neuronetics if, without the prior written consent of the Shareholder:

(i) there is any decrease in the amount of Consideration set out in the Arrangement Agreement;

(ii) there is any change in the form of Consideration set out in the Arrangement Agreement;

(c) termination by the Shareholder pursuant to Section 3.2;

- 10 -

(d) the Effective Date; and

(e) the Voting Support Outside Date.

4.2 Time of the Essence

Time is of the essence in this Agreement.

4.3 Effect of Termination

If this Agreement is terminated in accordance with the provisions of Section 4.1, no Party will have any further liability to perform its obligations under this Agreement except as expressly contemplated by this Agreement, and provided that neither the termination of this Agreement nor anything contained in Section 4.1 will relieve any Party from any liability for any breach by it of this Agreement, including from any inaccuracy in its representations and warranties and any non-performance by it of its covenants made herein.

4.4 Injunctive Relief

The Parties agree that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to injunctive and other equitable relief to prevent breaches or threatened breaches of this Agreement, and to enforce compliance with the terms of this Agreement, without any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief, this being in addition to any other remedy to which the Parties may be entitled at law or in equity.

4.5 Fiduciary Duty

Notwithstanding anything to the contrary herein, nothing herein shall restrict or limit any director or officer of Greenbrook from fulfilling his or her fiduciary duty as a director or officer of Greenbrook. If the Shareholder is a director of Greenbrook, the Shareholder and Neuronetics hereby acknowledge and agree that the Shareholder is bound hereunder solely in his capacity as a shareholder of Greenbrook and that the provisions hereof shall not be deemed or interpreted to bind the Shareholder in his capacity as a director of Greenbrook.

4.6 Waiver; Amendment

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the Party to be bound by the waiver. A Party’s failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a Party from any other or further exercise of that right or the exercise of any other right.

4.7 Entire Agreement

This Agreement constitutes the entire agreement among the Parties with respect to the subject matter hereof and supersedes all prior agreements and understandings among the Parties with respect thereto.
