CONFIDENTIAL TREATMENT REQUESTED

differences which may arise between the Parties out of or in relation to or in connection with this Agreement including, without limitation, any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement, then upon the request of either party by written notice, the parties agree to meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting between the executive officers of each Party. If the matter is not resolved within [***] days following the written request for discussions, either Party may then invoke the provisions of Section 9.2.

Any dispute, controversy, difference or claim which may arise between the parties out of or in relation to or in connection with this Agreement (including, without limitation, arising out of or relating to the validity, construction, interpretation, enforceability, breach, performance, application or termination of this Agreement) shall be settled by binding “baseball arbitration” as follows. Either party, following the end of the [***] day period referenced in Section 9.1, may refer such issue to arbitration by submitting a written notice of such request to the other party, with the arbitration to be held in the state where the other party’s principal office is located (or some other place as may be mutually agreed by the parties). Promptly following receipt of such notice, the parties shall meet and discuss in good faith and seek to agree on an arbitrator to resolve the issue, which arbitrator shall be neutral and independent of both parties and all of their respective Affiliates, shall have significant experience and expertise in licensing and partnering agreements in the pharmaceutical and biotechnology industries, and shall have some experience in mediating or arbitrating issues relating to such agreements. If the parties cannot agree on a single arbitrator within [***] days of request by a party for arbitration, then each Party shall select an arbitrator meeting the foregoing criteria and the two (2) arbitrators so selected shall select within [***] days of their appointment a third arbitrator meeting the foregoing criteria. Within [***] days after an arbitrator(s) is selected (in the case of the three-person panel, when the third arbitrator is selected), each Party will deliver to both the arbitrator(s) and the other party a detailed written proposal setting forth its proposed terms for the resolution for the matter at issue (the “Proposed Terms” of the party) and a memorandum (the “Support Memorandum”) in support thereof. The parties will also provide the arbitrator(s) a copy of this Agreement, as it may be amended at such time. Within [***] days after receipt of the other party’s Proposed Terms and Support Memorandum, each party may submit to the arbitrator(s) (with a copy to the other party) a response to the other party’s Support Memorandum. Neither party may have any other communications (either written or oral) with the arbitrator(s) other than for the sole purpose of engaging the arbitrator or as expressly permitted in this Section 9.2; provided that, the arbitrator(s) may convene a hearing if the arbitrator(s) so chooses to ask questions of the parties and hear oral argument and discussion regarding each party’s Proposed Terms. Within [***] days after the arbitrator’s appointment, the arbitrator(s) will select one of the two Proposed Terms (without modification) provided by the parties that he or she believes is most consistent with the intention underlying and agreed principles set forth in this Agreement. The decision of the arbitrator(s) shall be final, binding, and unappealable. For clarity, the arbitrator(s) must select as the only method to resolve the matter at issue one of the two sets of Proposed Terms, and may not combine elements of both Proposed Terms or award any other relief or take any other action.

9.3 Governing Law. This Agreement shall be governed by and construed under the substantive laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

9.4 Award. Any award to be paid by one Party to the other party as determined by the arbitrator(s) as set forth above under Section 9.2 shall be promptly paid in United States dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the losing party. Each party agrees to abide by the award rendered in any arbitration conducted pursuant to this Article 9, and agrees that, subject to the United States Federal Arbitration Act, 9 U.S.C. §§ 1-16, judgment may be entered upon the final award in any United States District Court located in New York and that other courts may award full faith and credit to such judgment in order to enforce such award. The award shall include interest from the date of any damages incurred for breach of the Agreement, and from the date of the award until paid in full, at a rate fixed by the arbitrator(s). With respect to money damages, nothing contained herein shall be construed to permit the arbitrator(s) or any court or any other forum to award consequential, incidental, special, punitive or exemplary damages. By entering into this agreement to arbitrate, the parties expressly waive any claim for consequential, incidental, special, punitive or exemplary damages. The only damages recoverable under this Agreement are direct compensatory damages.

9.5 Costs. Each party shall bear its own legal fees. The arbitrator(s) shall assess his or her costs, fees and expenses against the party losing the arbitration.

9.6 Injunctive Relief. Nothing in this Article 9 will preclude either party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such party or to preserve the status quo pending the arbitration proceeding.

9.7 Confidentiality. The arbitration proceeding shall be confidential and the arbitrator(s) shall issue appropriate protective orders to safeguard each party’s Confidential Information. Except as required by law, no party shall make (or instruct the arbitrator(s) to make) any public announcement with respect to the proceedings or decision of the arbitrator(s) without prior written consent of the other party. The existence of any dispute submitted to arbitration, and the award, shall be kept in confidence by the parties and the arbitrator(s), except as required in connection with the enforcement of such award or as otherwise required by applicable law.

9.8 Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason.

ARTICLE 10. TERMINATION

10.1 Upon any material breach or default of this Agreement by Licensee, OvaScience shall have the right to terminate this Agreement and the rights, privileges and license granted hereunder effective on sixty (60) days’ notice to Licensee. Such termination shall become automatically effective unless Licensee shall have cured any such material breach or default prior to the expiration of the sixty (60) day period.

10.2 Licensee shall have the right to terminate this Agreement at any time on sixty (60) days’ written notice to OvaScience.

Notwithstanding the foregoing, the right of termination under this Section 10.4 shall not apply in the event that a change of control of Licensee (such as if one or more equity owners of Licensee are bought out by one or more of the remaining equity owners of Licensee) is deemed to be a dissolution of Licensee absent any other evidence of an intention to dissolve the entity.

10.5 Upon termination of this Agreement for any reason, nothing in this Agreement shall be construed to release either party from any obligation accrued prior to the effective date of such termination and Articles 2, 5, 6, 7, 9, Sections 10.3, 10.4, and Article 12 shall survive any such termination.

10.6 Upon termination of this Agreement for any reason, Licensee and any sublicensee thereof shall immediately cease all manufacturing and sales of Licensed Products or Licensed Processes.

ARTICLE 12. MISCELLANEOUS PROVISIONS

12.1 Notwithstanding the provisions of Article 8 above, in the event that, pursuant to the United States Bankruptcy Code (11 USC§101 et seq.) or any amendment or successor thereto (hereinafter referred to as the “Bankruptcy Code”), a trustee in bankruptcy of Licensee (the “Trustee”), or Licensee as debtor in possession (the “Debtor”), is permitted to assume this Agreement and does so and, thereafter, desires to assign this Agreement to a third party, which assignment satisfies the requirements of the Bankruptcy Code, the Trustee, or the Debtor, as the case may be, will notify OvaScience of same in writing (hereinafter referred to as the “Notice”), specifying the consideration to be paid by the assignee and the other terms of the proposed assignment. The giving of the Notice will be deemed to constitute the grant of an option to OvaScience to have this Agreement assigned to it or to its designee for such consideration, or its equivalent in money, and upon such terms, as are specified in the Notice. The aforesaid option

CONFIDENTIAL TREATMENT REQUESTED

may be exercised only by written notice given by OvaScience to the Trustee or the Debtor, as the case may be, within [***] days after OvaScience’s receipt of the Notice from such party or such shorter period of time as may be deemed appropriate by the court in the bankruptcy proceeding. If OvaScience fails to give its notice to such party within the exercise period, such party may complete the assignment referred to in its Notice but only to the entity named in the Notice and upon the terms specified therein. Nothing contained herein will be deemed to preclude or impair any rights which OvaScience may have as a creditor in any bankruptcy proceeding or any other rights it may have at law, in equity, or by contract.

12.2 Each of the parties expressly acknowledges that, vis-a-vis the other party hereto, it is an independent contractor, and not the agent, employee or representative of the other. This Agreement shall, by itself, not be deemed to create a partnership, joint venture or principal-and-agent relationship between OvaScience and Licensee. Except as expressly permitted in this Agreement, neither party shall have the authority to bind the other to any agreement or obligation whatsoever, and neither party shall represent that it has any such right or authority to any third party.

12.3 The parties hereto acknowledge that this Agreement sets forth the entire agreement and understanding of the parties hereto as to the subject matter hereof, and shall not be subject to any change or modification except by the execution of a written instrument signed by the parties.

12.4 The provisions of this Agreement are severable, and in the event that any provision of this Agreement shall be determined to be invalid or unenforceable under any controlling body of the law, such invalidity or unenforceability shall not in any way affect the validity or enforceability of the remaining provisions hereof.

12.5 The failure of either party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other party.

12.6 Upon the request of the other party, each party shall execute and deliver such additional documents and perform such other acts as the other party may reasonably request, as may be necessary to effect the purposes and intent of this Agreement.

12.7 All titles and article headings contained in this Agreement are inserted only as a matter of convenience and reference and do not define, limit, extend, or describe the scope of this Agreement or the intent of any of its provisions.
