(C) making an offer or proposal which if effected would result in a business combination, which offer or proposal is made public. unless the Company files a recommendation statement on Schedule 14D-9 (or

Company’s stockholders to reject such offer (provided that if any transaction contemplated by such offer is terminated or abandoned, then the provisions of this Section 15.7(c)(i) shall again become effective); or 

  
 - 4 - 













 (b) the Company (A) entering into or publicly announcing its intention
to enter into a definitive agreement with a third party to effectuate a business combination or any transaction which will result in the acquisition, directly or indirectly, by any person or group of beneficial ownership of at least [**]% of the

expiration or termination of the Standstill Period will not terminate or otherwise affect any of the other provisions of this Agreement. 

2.4 The Company represents and warrants that it does not have in effect a confidentiality agreement entered into in connection with potential
business combination discussions that contains no standstill provisions or standstill provisions less restrictive than those included in this Section 2. If during the Standstill Period, the Company enters into any confidentiality or similar
agreement with any other party (the “Counterparty”) that relates to a transaction that could reasonably be expected to result in a Trigger Event and that either (i) does not contain a standstill obligation on the part of such
Counterparty or (ii) contains standstill provisions that are less restrictive upon the Counterparty than the standstill provisions set forth in this Agreement, the Company shall promptly offer to eliminate or amend (as the case may be) the
standstill provisions set forth in this Agreement to be in a form substantially identical to the standstill provisions contained in such other agreement. 

2.5 Except as expressly set forth in this Section 2, nothing in this Agreement, the Purchase Agreement or the Collaboration Agreement
(including, but not limited to, the restrictions on the disclosure and use of information set forth therein, provided that any disclosure or use of information by Investor does not otherwise result from a breach of this Section 2.5) shall
restrict or prohibit Investor or any of its Affiliates from taking any action described in Section 2.1. 
 2.6 Investor and its
Affiliates shall not be restricted from taking any of the actions contemplated by Section 2.1 after the expiration or termination of the Standstill Period, subject in all cases to the other provisions of this Agreement. 

2.7 Investor agrees not to publicly request or otherwise publicly disclose that the Company amend or waive any provision of Section 2
(including this Section 2.7); provided, that nothing contained in this Agreement shall prevent Investor from making confidential communications to the Company’s Chief Executive Officer and/or its Board of Directors (including,
without limitation, a confidential proposal to acquire the Company or a confidential request to amend or waive any provision of this Section 2.7, in each case that does not result in public disclosure by Investor of the making of such proposal
or request). If at any time Investor is approached by any third party concerning its or such Third Party’s participating in any of the types of matters referred to in this Section 2.7, Investor will not communicate with such third party
concerning such participation.

3.14 Specific Performance. The Company and the Investor hereby acknowledge that if any party refuses or otherwise fails to act, or to
cause its Affiliates to act, in accordance with the provisions of this Agreement, such refusal or failure would result in irreparable injury to the Company or the Investor, as the case may be, the exact amount of which may be difficult to ascertain

hereunder do not in any way conflict with the rights granted to any other holder of the Company’s securities under any other agreements.
