This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto; provided that this Agreement shall not be effective until the Transaction Agreement is executed by all parties thereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 6.13. Entire Agreement. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof.

Section 6.14. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 6.15. Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that the non-breaching party shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in the courts referred to in Section 6.10, in addition to any other remedy to which they are entitled at law or in equity.

Section 6.16 Shareholder Obligations Several and Not Joint. The obligations of each VC Shareholder hereunder shall be several and not joint and no VC Shareholder shall be liable for any breach of the terms of this Agreement by any other VC Shareholder.

Section 6.17 No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the Transaction Agreement is executed by all parties thereto and (b) this Agreement is executed by all parties hereto (which the parties agree has occurred immediately following the execution of the Transaction Agreement by all parties thereto).

Section 6.18. Equal Treatment. It is acknowledged that, in connection with the transactions contemplated by the Transaction Agreement, the Investor may enter, or has entered, into the Tender and Support Agreements with the VC Funds other than the VC Shareholders. To the extent that any such Tender and Support Agreement grants to any VC Fund rights thereunder that are more favorable to such VC Fund than the rights of the VC Shareholders set forth herein (other than with respect to Section 1.01(a)(ii)) or waives a material obligation of such VC Fund that is also set forth herein, the Investor agrees that it shall offer the same rights or waiver, as applicable, to the VC Shareholders; provided, however, the Investor’s obligation with respect to Section 1.01(a)(ii) only applies to the extent Affiliates of Third Rock Ventures, L.P. are granted more favorable rights, or receive a waiver of the obligations of such VC Fund, in each case with respect to the subject matter covered by Section 1.01(a)(ii). Each such offer shall be made by the Investor’s prompt delivery to the VC Shareholders of the text of the applicable rights or waiver, as applicable, and such offer shall be deemed declined by the VC Shareholders if not accepted by such VC Shareholders in writing within 10 Business Days after such offer is delivered. The Investor shall attach a schedule to this Agreement that reflects any such rights or waivers, as applicable, that are accepted by the VC Shareholders, and such schedule shall become a part of this Agreement. All determinations with respect to the VC Shareholders’ rights under this paragraph shall be made by the Investor taking into account all facts and circumstances applicable at the time of determination.
