Each representative as qualified above may serve on more than one (1) Committee as appropriate in view of the individual’s expertise. Each Party may replace its Committee representatives at any time upon prior written notice to the other Party. Each Committee shall have a chairperson selected from among the duly appointed representatives; the chairperson of each Committee shall serve for a two-year term and the right to designate a chairperson shall alternate between the Parties, with OvaScience selecting the chairperson first for the JSC, and Intrexon selecting the chairperson first for the IPC. The chairperson of each Committee shall be responsible for calling meetings, preparing and circulating an agenda in advance of each meeting of such Committee, and preparing and issuing minutes of each meeting within a reasonable time thereafter. Each member of the Committee shall have the opportunity to provide comments on the draft minutes. Draft minutes shall be approved, disapproved and revised as soon as practicable. Upon approval, final minutes of each meeting shall be circulated to the members of the JSC by the chairperson.

(b) Meetings. Each Committee shall hold meetings at such times as it elects to do so, but in no event shall such meetings be held less frequently than once every six (6) months; provided that, both Parties may agree to suspend activities of the IPC until such time as one Party informs the other Party in writing of its desire to reactivate the IPC, at which point the Parties will thereafter schedule and hold the next meeting for the reactivated IPC within one (1) month. Meetings of any Committee may be held in person or by means of telecommunication (telephone, video, or web conferences). To the extent that a Committee holds any meetings in person, the Parties will alternate in designating the location for such in-person meetings, with OvaScience selecting the first meeting location for each Committee. A reasonable number of additional representatives of a Party may attend meetings of a Committee in a non-voting capacity so long as such additional non-voting representatives each either (A) are an employee of

CONFIDENTIAL TREATMENT REQUESTED

a Party or an employee an Affiliate of a Party, or (B) are not an employee of either Party (or Affiliates thereof) but prior to attending any such meeting (i) such additional non-voting representative agrees in writing to be bound to the terms of this Agreement for the treatment and ownership of Confidential Information and Inventions (or is bound by law or contractual agreement with such Party consistent with such terms), and (ii) the other Party consents to the attendance of such non-employee additional representative, which consent shall not be unreasonably withheld. Each Party shall be responsible for all of its own expenses of participating in any Committee. For clarity, however, if Intrexon employee or agent both (i) serves as a representative on a Committee, and (ii) contributes under the Work Plan by providing labor in the course of Intrexon’s providing of manufacturing or support services under Sections 4.5 and 4.6, Intrexon shall not be prevented from recouping the Fully Loaded Costs otherwise derived from the labor of that employee or agent in the course of providing manufacturing or support services as set forth in Sections 4.5 and 4.6 below to the extent that such Fully Loaded Costs do not include any time such Intrexon representative spent on Committee activities.

(c) Meeting Agendas. Each Party will disclose to the other Party the proposed agenda items along with appropriate information to be discussed at the meeting at least three (3) business days in advance of each meeting of the applicable Committee; provided, that a Party may provide its agenda items to the other Party within a lesser period of time in advance of the meeting, or may propose that there not be a specific agenda for a particular meeting, so long as such other Party consents to such later addition of such agenda items or the absence of a specific agenda for such Committee meeting.

(d) Limitations of Committee Powers. Each Committee shall have only such powers as are specifically delegated to it hereunder or from time to time as agreed to in writing by the mutual consent of the Parties and shall not be a substitute for the rights of the Parties. Without limiting the generality of the foregoing, no Committee shall have any power to amend this Agreement. Any amendment to the terms and conditions of this Agreement shall be implemented pursuant to Section 12.7 below.

2.4 Committee Decision-Making. If a Committee is unable to reach unanimous consent on a particular matter within thirty (30) days of its initial consideration of such matter, then either Party may provide written notice of such dispute to the Executive Officer of the other Party. The Executive Officers of each of the Parties will meet at least once in person or by means of telecommunication (telephone, video, or web conferences) as promptly as possible to discuss the dispute and use their good faith efforts to resolve the dispute within thirty (30) days after submission of such dispute to the Executive Officers. If any such dispute is not resolved by the Executive Officers within thirty (30) days after submission of such dispute to such Executive Officers, then the dispute shall be resolved as specified in the applicable subsection below.

(a) Casting Vote at JSC. If a dispute at the JSC is not resolved pursuant to Section 2.4 above, then the Executive Officer of OvaScience shall have the authority to finally resolve such dispute.

(b) Casting Vote IPC. If a dispute at the IPC is not resolved pursuant to Section 2.4 above, then the Executive Officer of Intrexon shall have the authority to finally

CONFIDENTIAL TREATMENT REQUESTED

resolve such dispute, provided that such authority shall be shared by the Parties with respect to Product-Specific Program Patents (i.e., neither Party shall have the casting vote on such matters, and any such disputes shall be resolved pursuant to Article 11).

(c) Other Committees. If any additional Committee or subcommittee other than those set forth in Section 2.2(b) is formed, then the Parties shall, at the time of such formation, agree on which Party shall have the authority to finally resolve a dispute that is not resolved pursuant to Section 2.4 above.

(d) Restrictions. Neither Party shall exercise its right to finally resolve a dispute at a Committee in accordance with this Section 2.4 in a manner that (i) excuses such Party from any of its obligations specifically enumerated under this Agreement; (ii) expands the obligations of the other Party under this Agreement; (iii) negates any consent rights or other rights specifically allocated to the other Party under this Agreement; (iv) purports to resolve any dispute involving the breach or alleged breach of this Agreement; (v) resolves a matter if the provisions of this Agreement specify that mutual agreement is required for such matter; or (vi) would require the other Party to perform any act that is inconsistent with applicable law.

2.5 Authorization of Committee Representatives. Each representative serving on a Committee shall be responsible for ensuring that he or she acts only as duly authorized by its respective Party and obtains any advance approvals, delegations, or other authorizations from his or her respective Party in advance of making any Committee votes.

2.6 Option to Expand Field. At any time during the Term, OvaScience, at its sole discretion, may opt to expand the Field as set forth in Section 2.6(a) below (the “Field Option”) by sending Intrexon written notice which shall state that OvaScience is executing its option to expand the Field pursuant to this Section 2.6. Immediately upon receipt by Intrexon of such notice and without any further action by either Party under this Agreement, (a) the Field Option will be deemed exercised for purposes of this Agreement, (b) the definition of Field as used in this Agreement will thereafter be deemed to be defined as set forth below in Section 2.6(a), and (c) all rights and obligations of the Parties set forth in this Agreement defined in part by, or with respect to, the Field (including, without limitation, the license rights granted under Section 3.1, the exclusivity obligations imposed by Section 3.5, and the diligence obligations imposed by Section 4.4) will automatically and immediately change such that from the time of such execution forward those rights and obligations will apply to the Field as so-amended.

(a) Upon exercise of the Field Option by OvaScience in accord with Section 2.6 above, the language of Section 1.21 of this Agreement will be struck and replaced with the following language :

“Field” means, irrespective of whether such requires regulatory approval, (i) the ex vivo differentiation of OPCs into mature, fertilizable oocytes and/or (ii) the application of any discoveries made by the Parties during the Term under the prior clause (i) relating to the production and purification technologies to the improvement of the Existing Product and to provide enhanced

Notwithstanding the foregoing sentence, OvaScience may utilize academic and non-profit Third Parties for the pre-clinical and clinical development of any product, including Collaboration Products, to the extent consistent with Articles 6 and 7 of this Agreement. For the avoidance of doubt, (A) OvaScience may pursue and conduct the development and implementation of manufacturing changes designed to reduce the COGS of the Existing Product outside of the OPC Program (i) prior to execution of the Field Option, and (ii) after execution of the Field Option so long as such pursuit and conduct does not utilize Inventions or Intrexon IP, or otherwise utilize Third Party genetic or cell processing technology in lieu of using Intrexon Channel Technology and (B) it shall not be a violation of any provision of this Section 3.5 for OvaScience to contract with or otherwise employ a Third Party JSC-approved contractor in lieu of Intrexon for activities described in a Work Plan if OvaScience reasonably concludes that (i) Intrexon cannot meet and will materially exceed the IND Due Date, and (ii) pursuing the development with such Third Party will deliver an IND-Enabling Package materially faster than with Intrexon. Notwithstanding the foregoing, it shall not be a

CONFIDENTIAL TREATMENT REQUESTED

violation of this Section 3.5(b) (i) for OvaScience to license Patents and intellectual property it Controls to JV for use within the JV Field, and/or (ii) for JV to participate in the business operations of JV according to OvaScience’s rights therein as an equity holder or to collaborate with JV with regard to the research, development, and Commercialization of products in the JV Field.

3.6 Off Label Use. For purposes of clarity, (a) the use by direct or indirect purchasers or other users of Collaboration Products or Improved Products outside the Field (an “off label use”) shall not constitute a breach by OvaScience of the terms of Section 3.4 , provided that neither OvaScience nor its Affiliate (nor any Third Party under contract with either of them) marketed or promoted Collaboration Products or Improved Products for such off-label use; and (b) an “off-label use by any direct or indirect purchasers or other users of products sold by Intrexon, an Intrexon Affiliate, or a Third Party sublicensee, collaborator, or partner of Intrexon shall not constitute a breach by Intrexon of the terms of Section 3.4, provided that neither Intrexon nor its Affiliate (nor any Third Party under contract with either of them) marketed or promoted such products for such off-label use.

3.7 No Prohibition on Intrexon. Except as explicitly set forth in Sections 3.1 and 3.4, nothing in this Agreement shall prevent Intrexon from practicing or using the Intrexon Materials, Intrexon Channel Technology, and Intrexon IP for any purpose, and to grant to Third Parties the right to do the same. Without limiting the generality of the foregoing, OvaScience acknowledges that Intrexon has all rights, in Intrexon’s sole discretion, to make the Intrexon Materials, Intrexon Channel Technology (including any genetic materials used in a Collaboration Product), and Intrexon IP available to Third Party channel partners or collaborators for use in fields outside of the Field.

3.8 Rights to Clinical and Regulatory Data. OvaScience shall own and control all clinical and pre-clinical data and regulatory filings relating to Commercialization of Collaboration Products and Improved Products during the Term. OvaScience shall provide (or shall cause an applicable Product Sublicensee to provide) to Intrexon at Intrexon’s reasonable request and upon OvaScience’s consent (which consent shall not be unreasonably denied, delayed, or conditioned) copies of all clinical and non-clinical data and reports, regulatory filings, and communications from regulatory authorities that relate specifically and solely to Intrexon IP that is included in Collaboration Products. To the extent that there exist any clinical and non-clinical data and reports, regulatory filings, and communications from regulatory authorities owned by OvaScience (or a Product Sublicensee) that relate to Intrexon IP, OvaScience shall provide (or shall cause an applicable Product Sublicensee to provide) to Intrexon copies of the portions of such data, reports, filings, and communications that relate specifically and solely to Intrexon IP. Subject to Section 3.1 and Section 3.5, Intrexon shall be permitted, directly or in conjunction with or through partners or other channel collaborators, to reference any such data, reports, filings, and communications relating specifically and solely to Intrexon IP in regulatory filings made to obtain regulatory approval for (i) products for use in fields outside the Field, and/or (ii) products of JV for use only in the JV Field. Intrexon shall have the right to provide a written request to OvaScience to use any such information in developing and Commercializing products outside the Field, or products in the JV Field, and to license any Third Parties to do so and OvaScience shall not unreasonably refuse any such request

CONFIDENTIAL TREATMENT REQUESTED

provided that OvaScience reasonably determines that the proposed use by Intrexon will not adversely affect OvaScience’s ongoing business. Notwithstanding the provisions of this Section 3.7, Intrexon shall not, outside of the OPC Program, utilize any OvaScience clinical and non-clinical data or reports in support of obtaining regulatory approval for a product for use in the Field or for a product that would compete with Collaboration Products in the Field.

Intrexon shall use Diligent Efforts to perform any Work Plan support services set forth in Section 4.6.

(b) Without limiting the generality of the foregoing, Intrexon may, from time to time, notify OvaScience that it believes it has identified a Superior Therapy, and in such case Intrexon shall provide to OvaScience its then-available information about such therapy and reasonable written support for its conclusion that the therapy constitutes a Superior Therapy. OvaScience shall have the following obligations with respect to such proposed Superior Therapy: (i) within sixty (60) days after such notification, OvaScience shall prepare and deliver to the JSC for review and approval a development plan detailing how OvaScience will pursue the Superior Therapy (including a proposed budget); (ii) OvaScience shall revise the development plan as directed by the JSC; and (iii) following approval of the development plan by the JSC, OvaScience shall use Diligent Efforts to pursue the development of the Superior Therapy under the OPC Program in accordance with such development plan. To the extent that Intrexon has in fact identified a Superior Therapy, Intrexon shall have the termination right set forth in Section 10.2(c) (subject to the final sentence of this Section 4.4(b) and the limitation set forth therein) if OvaScience fails to comply with the foregoing obligations (i)-(iii), or if OvaScience unreasonably exercises its casting vote at the JSC to either (x) prevent the approval of a development plan for a Superior Therapy; (y) delay such approval more than sixty (60) days after delivery of the development plan to the JSC; or (z) approve a development plan that is insufficient in view of the nature and magnitude of the opportunity presented by the Superior Therapy. For clarity, (i) any dispute arising under this 4.4, including any dispute as to whether a project proposed by Intrexon in fact constitutes a Superior Therapy (as with any other dispute under this Agreement) shall be subject to dispute resolution in accordance with Article 11, and (ii) Intrexon shall have no right to terminate this Agreement pursuant to Section 10.2(c), and the cure period provided in Section 10.2(c) shall be stayed, during the period any such dispute is subject to such dispute resolution process.

(c) The activities of OvaScience’s Affiliates and any permitted sublicensees shall be attributed to OvaScience for the purposes of evaluating OvaScience’s fulfillment of the obligations set forth in this Section 4.4.

4.5 Manufacturing. Intrexon shall have the option and, in the event it so elects, shall use Diligent Efforts, to perform any manufacturing activities in connection with the OPC Program that relate to the Intrexon Materials or bulk quantities of other components of Collaboration Products or Improved Products, either itself or through the use of a suitable Third Party contract manufacturer. To the extent that Intrexon so elects, OvaScience and Intrexon shall negotiate and execute a separate manufacturing and supply agreement, which agreement will establish and govern the production, quality assurance, and regulatory activities associated with manufacture of Intrexon Materials or bulk quantities of other components of Collaboration Products or Improved Products. Except as provided in Section 4.1, any manufacturing undertaken by Intrexon pursuant to the preceding sentence shall be performed in exchange for cash payments equal to Intrexon’s Fully Loaded Cost in connection with such manufacturing, on

CONFIDENTIAL TREATMENT REQUESTED

terms to be negotiated by the Parties in good faith. In the event that Intrexon does not elect to manufacture Intrexon Materials or bulk quantities of other components of Collaboration Products or Improved Products, then (a) Intrexon shall provide written notice of same to OvaScience, (b) the Parties will, through the JSC, develop a written work plan (the “Technology Transfer Work Plan”) describing the activities (the “Technology Transfer Activities”) to be performed by Intrexon to implement the transfer to OvaScience or a contract manufacturer selected by OvaScience of all Information Controlled by Intrexon that is (i) related to the manufacturing of such Intrexon Materials or bulk qualities of other components of Collaboration Products for use in the Field (but not pertaining solely to the JV Field) and (ii) reasonably necessary to enable OvaScience or such contract manufacturer (as appropriate) for the sole purpose of manufacturing such Intrexon Materials or bulk quantities of other components of Collaboration Products, which may include providing OvaScience and/or such Third Party with the training, documentation and other information relating to the manufacturing of such Intrexon Materials or bulk qualities of other components of Collaboration Products for use in the Field and making appropriately trained personnel available for consultation and advice upon the reasonable request of OvaScience and/or such Third Party to the extent reasonably necessary to enable OvaScience and/or such Third Party to manufacture such Intrexon Materials or bulk qualities of other components of Collaboration Products for use in the Field and (c) Intrexon shall promptly undertake the Technology Transfer Activities. The costs and expenses incurred by Intrexon in carrying out such Technology Transfer Activities shall be borne by OvaScience. Any manufacturing Information transferred hereunder to OvaScience or its contract manufacturer shall not be further transferred to any Third Party, including any Product Sublicensee, or any OvaScience Affiliate without the prior written consent of Intrexon; provided, however, that Intrexon shall not unreasonably withhold such consent if necessary to permit OvaScience to switch manufacturers.

4.6 Support Services.

(a) The JSC will meet promptly following the Effective Date and prepare and approve the initial Work Plan under which Intrexon will provide support services to OvaScience for the research and development of Collaboration Products (and, to the extent OvaScience exercises the Field Option, Improved Products) under the OPC Program, which initial Work Plan may be amended from time to time by the JSC. The Work Plan shall set forth activities and deliverables to be achieved on or before the IND Due Date) and shall include the timelines, estimated costs (including a detailed budget that shall include all estimated Fully Loaded Costs). OvaScience will compensate Intrexon for services under this Section 4.6 with cash payments equal to Intrexon’s Fully Loaded Cost in accord with the Work Plan. Additionally, from time to time, on an ongoing basis, OvaScience may request, or Intrexon may propose, that Intrexon perform certain additional services with respect to researching and developing new Collaboration Products or improving the manufacturing or processing methods for the Existing Product to produce Improved Products. If either Party proposes that Intrexon perform additional Services, not specifically provided for in the applicable Work Plan, Intrexon shall prepare a draft revised Work Plan describing in reasonable detail the nature of such additional Services, and submit such revised Work Plan to the JSC for its review and written approval. To the extent that the Parties mutually agree that Intrexon should perform such additional services, it is understood that

CONFIDENTIAL TREATMENT REQUESTED

Intrexon would be compensated for such additional services by cash payments equal to Intrexon’s Fully Loaded Cost in connection with such services.

(b) OvaScience shall not be obligated to pay to Intrexon for the conduct of any support services provided under this Section 4.6 any amounts that exceed by more than [***] percent ([***]%) the budget specifically allocated for the applicable activities in the associated JSC-approved budget under the Work Plan, unless (a) the JSC shall amend the Work Plan and associated budget to accommodate any material overage, or (b) OvaScience otherwise agrees in writing to pay the amounts in material excess to Intrexon. In the event that, in performance under the Work Plan, Intrexon determines that the JSC-approved budget is in some way insufficient to complete performance of the tasks under the Work Plan, it will notify the JSC as soon as practical after determining such, providing sufficient detail to enable the JSC to promptly review the budget insufficiency and revise the Work Plan and associated budget. The JSC (i) shall confer and/or meet (including electronically) as soon as practical after receiving such notice from Intrexon to consider amending the Work Plan, and (ii) shall use best efforts to provide a final decision regarding whether, and (if so) how, to amend the Work Plan and associated budget in order to expand the budget and/or minimize the activities under the Work Plan to reconcile budget with the then-current expectations and projections for expenditures under the Work Plan. Intrexon may discontinue performance under a Work Plan if continuing under the Work Plan to the extent continuing would cause Intrexon to exceed by more than [***] percent ([***]%) the applicable budget, such discontinuance being permissible until such time as the JSC, with the consent of OvaScience, has amended the Work Plan to redress the issue in accord with this Section 4.6(b). To the extent that the inability of the JSC to approve an amended Work Plan and/or associated budget causes Intrexon to materially discontinue performance under the Work Plan toward producing the IND-Enabling Package, any number of days of discontinuance by Intrexon until JSC approval for amendment is actually granted exceeding [***] business days from Intrexon’s notice under this Section 4.6(b) shall be includable in the determination of OvaScience Delay.

4.7 Compliance with Law. Each Party shall comply, and shall ensure that its Affiliates, comply, and shall include in any agreement with any permitted Third Party sublicensee or subcontractor a covenant that shall provide that such Third Party shall comply with, all applicable laws, regulations, and guidelines applicable to the OPC Program, including without limitation those relating to the transport, storage, and handling of Intrexon Materials and Collaboration Products, and Improved Products.

4.8 Trademarks and Patent Marking. OvaScience shall ensure that the packaging, promotional materials, and labeling for Collaboration Products and Improved Products, shall carry as appropriate the applicable Intrexon Trademark(s), as required by and/or in compliance with applicable laws and regulations. Consistent with the U.S. patent laws, OvaScience shall ensure that Collaboration Products and Improved Products, or their respective packaging or accompanying literature as appropriate, bear applicable and appropriate patent markings for Intrexon Patent numbers. OvaScience shall provide the IPC (or, after termination, Intrexon) with representative samples of all products, product packaging, literature, brochures, signs, and advertising materials prepared by OvaScience which bear, display, or include any reference to the Intrexon Trademarks or patent markings prior to using or disseminating such

CONFIDENTIAL TREATMENT REQUESTED

materials. OvaScience acknowledges Intrexon’s sole ownership of the Intrexon Trademarks and agrees not to take any action inconsistent with such ownership. OvaScience covenants that it shall not use any trademark confusingly similar to any Intrexon Trademarks in connection with any products (including any Collaboration Product or Improved Product. OvaScience shall comply with reasonable policies provided in writing by Intrexon from time-to-time to maintain the goodwill and value of the Intrexon Trademarks.

4.9 Technology Transfer by OvaScience. As soon as practical following the approval of the original Work Plan by the JSC, OvaScience will provide Intrexon with any Information and proprietary materials Controlled by OvaScience and described in the Work Plan to the extent required for Intrexon to perform its obligations under the Work Plan. For purposes of determining the IND Due Date, the completion of the initial technology transfer from OvaScience to Intrexon shall be considered to have occurred at such time when OvaScience has transferred sufficient Information and proprietary materials under its Control to enable Intrexon to initiate its performance under the Work Plan, and, in any event, no later than [***] ([***]) months from the Effective Date. For clarity, failures of OvaScience to provide necessary materials, information, or technology required by Intrexon for timely performance and completion of its obligations under the Work Plan shall be eligible for inclusion in any determination of OvaScience Delay (to the extent such failures otherwise would qualify under Section 1.58) irrespective of whether such failure occurs after the completion of the initial technology transfer from OvaScience under the prior sentence.

CONFIDENTIAL TREATMENT REQUESTED

Collaboration Products (excluding Improved Products). For purposes of clarity, in the event that there are negative Net Sales for a particular Collaboration Product (excluding Improved Products) in any calendar quarter, (i) neither OvaScience nor Intrexon shall owe any payments hereunder with respect to such Collaboration Product and (ii) any such negative Net Sales that results from Excess Product Liability Costs may be carried forward to future calendar quarters and offset against positive Net Sales in such future calendar quarters for the same Collaboration Product; provided, that, except as set forth in the preceding sentence, OvaScience shall not be permitted to carry forward any negative Net Sales to subsequent quarters.

(b) The percentage royalty applicable to each Collaboration Product under Section 5.2(a) above (“Applicable Percentage”) shall have an initial rate of [***] percent ([***]%), which shall be adjusted downward as set forth in the subsections (i) through (iii) immediate below, as applicable.

(i) In the event that Intrexon does not deliver to OvaScience an IND-Enabling Package for a Collaboration Product by the IND Due Date, the Applicable Percentage for such Collaboration Product shall decrease by (A) [***] ([***]) basis points (i.e., [***]%) for each [***] ([***]) day period between the IND Due Date and the date the IND-Enabling Package is actually received by OvaScience during the first [***] months after the IND Due Date, and (B) [***] ([***]) basis points (i.e., [***]%) for each [***] ([***]) day period thereafter until the IND-Enabling Package is actually received by OvaScience.

(ii) In the event that the development and/or Commercialization of any Collaboration Product requires that OvaScience pay royalties to a Third Party, the Applicable Percentage shall decrease by [***] basis points (i.e., [***]%) for every [***] ([***]) basis points (i.e., [***]%) of royalty that is ultimately paid by OvaScience to such Third Party.

(iii) In no event shall Applicable Percentage applicable to any Collaboration Product (excluding an Improved Product) be reduced by application of Sections 5.2(b)(i) and/or 5.2(b)(ii) to be less than [***] percent ([***]%).

5.3 Royalty Reduction for Failure to Deliver IND-Enabling Package. Notwithstanding the foregoing, the Applicable Percentage for a given Collaboration Product (excluding an Improved Product) shall be [***] percent ([***]%) in the event that OvaScience elects to pursue the development of such Collaboration Product by itself or with a Third Party because OvaScience reasonably concludes that (i) Intrexon cannot meet and shall materially exceed the IND Due Date, and (ii) pursuing the development without Intrexon will deliver an IND-Enabling Package materially faster than with Intrexon.

5.4 Payments for Improved Products. No later than [***] ([***]) days after each calendar quarter in which there were COGS Savings realized by OvaScience (including permitted Affiliates and sublicensees thereof) from the sale of any Improved Product in the Field, OvaScience shall pay to Intrexon a royalty equal to [***] percent ([***]%) of the COGS Savings.

5.7 Method of Payment. Payments due to Intrexon under this Agreement shall be paid in United States dollars by wire transfer to a bank in the United States designated in writing by Intrexon. All references to “dollars” or “$” herein shall refer to United States dollars.

5.8 Payment Reports and Records Retention. Within [***] ([***]) days after the end of each calendar quarter during which positive Net Sales or COGS Savings have been generated, a Milestone Event has been achieved, or a negative Net Sales has occurred, OvaScience shall deliver to Intrexon a written report that shall contain at a minimum for the applicable calendar quarter:

(a) gross sales of each Collaboration Product (on a country-by-country basis);

(b) itemized calculation of Net Sales of each Collaboration Product, showing all applicable deductions;

(c) itemized calculation of COGS Savings, showing the calculation of COGS for the Existing Product prior to being improved under the OPC Program and the COGS calculation for the Improved Product (including any mutually agreed exclusions per Section 1.9);

(d) the amount of any negative Net Sales of each Collaboration Product for the applicable calendar quarter, and any negative Net Sales amount carried forward from a prior quarter and applied during the present quarter (as per Section 5.2(a));

(e) the amount of the payment (if any) due pursuant to each of Sections 5.2(a) through 5.2(c);

(f) the amount of the payment (if any) made by OvaScience, or that has become due by the achievement of the Milestone Event, during the preceding calendar quarter under 5.3;

(g) the amount of taxes, if any, withheld to comply with any applicable law; and

(h) the exchange rates used in any of the foregoing calculations.

For [***] ([***]) years after (a) the sale or other commercial use of each Collaboration Product or Improved Product, or (b) the date on which OvaScience reports to Intrexon any component item OvaScience incorporated into its calculation of Net Sales, COGS, or COGS Savings,

OvaScience shall keep (and shall ensure that its Affiliates shall keep and, if applicable, shall include in any agreement with a Third Party permitted sublicensee a covenant that shall provide that such (sub)licensees shall keep) complete and accurate records of such sales, commercial use, or component item in sufficient detail to confirm the accuracy of the payment calculations hereunder.

5.9 Audits.

(a) Audit Rights of Intrexon.

(i) Upon the written request of Intrexon, OvaScience shall permit an independent certified public accounting firm of internationally recognized standing selected by Intrexon, and reasonably acceptable to OvaScience, to have access to and to review, during normal business hours and upon not less than [***] ([***]) days prior written notice, the applicable records of OvaScience and its Affiliates to verify the accuracy and timeliness of the reports and payments made by OvaScience under this Agreement. Such review may cover the records for sales made in any calendar year ending not more than [***] ([***]) years prior to the date of such request. The accounting firm shall disclose to both Parties whether the payments made by OvaScience are accurate and the amount of any discrepancies. Such audit may not be conducted more than once in any calendar year or more than once with respect to sales of a particular Collaboration Product or Improved Product in a particular period.

(ii) If such accounting firm concludes that additional amounts were owed during such period, OvaScience shall pay additional amounts, with interest from the date originally due as set forth in Section 5.8, within [***] ([***]) days of receipt of the accounting firm’s written report. If the amount of the underpayment is greater than [***] percent ([***]%) of the total amount actually owed for the period audited, then OvaScience shall in addition reimburse Intrexon for all costs related to such audit; otherwise, Intrexon shall pay all costs of the audit. In the event of overpayment, any amount of such overpayment shall be fully creditable against amounts payable for the immediately succeeding calendar quarter(s).

(iii) Intrexon shall (i) treat all information that it receives under this Section 5.6 in accordance with the confidentiality provisions of Article 7 and (ii) cause its accounting firm to enter into an acceptable confidentiality agreement with OvaScience obligating such firm to retain all such financial information in confidence pursuant to such confidentiality agreement, in each case except to the extent necessary for Intrexon to enforce its rights under this Agreement.

(b) Audit Right of OvaScience. Intrexon shall keep complete and accurate books and financial records pertaining to the number of FTEs utilized, the applicable FTE Cost and external expenses incurred in conducting the OPC Program, which books and financial records shall be retained by Intrexon until [***] ([***]) years after the end of the calendar year to which they pertain. Upon [***] ([***]) days written notice, OvaScience shall have the right to appoint at its expense an independent certified public accountant reasonably acceptable to Intrexon to audit the books and financial records of Intrexon relating to the number of FTEs utilized, the applicable FTE Cost and external expenses incurred in conducting the OPC Program

CONFIDENTIAL TREATMENT REQUESTED

during any calendar year; provided, that, OvaScience shall not have the right to audit any calendar year more than once or more than [***] ([***]) years after the end of such calendar year or to conduct more than one such audit in any twelve-month period. All books and financial records made available for audit shall be deemed to be Confidential Information of Intrexon. The results of each audit, if any, shall be reported in writing to both Parties promptly (but in no event later than [***] ([***]) days) after the audit and shall be binding on both Parties. In the event there was an error relating to the reported FTEs utilized, the applicable FTE Cost and external expenses incurred in conducting the OPC Program, (a) if the effect of the error resulted in an overpayment by OvaScience, Intrexon shall promptly (but in any event no later than [***] ([***]) days) after Intrexon’s receipt of the report so concluding, make payment to OvaScience of the overpayment and (b) if the effect of the error resulted in an underpayment by OvaScience, then OvaScience shall promptly (but in no event later than [***] ([***]) days after OvaScience’s receipt of the report so concluding) make payment to Intrexon of the underpayment amount. OvaScience shall bear the full cost of such audit unless such audit discloses an over reporting by Intrexon of more than [***] percent ([***]%) of the aggregate amount of FTE Costs and external expenses reportable in any calendar year, in which case Intrexon shall reimburse OvaScience for all reasonable costs incurred by OvaScience in connection with such audit.

5.10 Taxes. The Parties will cooperate in good faith to obtain the benefit of any relevant tax treaties to minimize as far as reasonably possible any taxes which may be levied on any amounts payable hereunder. OvaScience shall deduct or withhold from any payments any taxes that it is required by applicable law to deduct or withhold. Notwithstanding the foregoing, if Intrexon believes that it is entitled under any applicable tax treaty to a reduction of the rate of, or the elimination of, applicable withholding tax, it may deliver to OvaScience or the appropriate governmental authority (with the assistance of OvaScience to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve OvaScience of its obligation to withhold tax, and OvaScience shall provide OvaScience with reasonable assistance so that Intrexon may obtain the reduced rate of withholding tax, or dispense with withholding tax, as the case may be. If Intrexon provides OvaScience with evidence reasonably satisfactory to OvaScience that Intrexon is entitled to the reduced rate or to dispense with such rate, at least [***] ([***]) days prior to the time that the payment is due, OvaScience shall comply with such adjustment. If, in accordance with the foregoing, OvaScience withholds any amount, it shall make timely payment to the proper taxing authority of the withheld amount, and send to Intrexon proof of such payment within [***] ([***]) days following that latter payment.

5.11 Late Payments. Any amount owed by OvaScience to Intrexon under this Agreement that is not paid within the applicable time period set forth herein shall accrue interest at the lower of (a) [***] percent ([***]) per month, compounded, or (b) [***].

Joint Program Inventions so as to enable Intrexon sufficient lead time to prevent an unwanted loss of rights by Intrexon to Intrexon IP, including allowing Intrexon to file on and prosecute Patents for such; (v) use qualified patent counsel reasonably acceptable to Intrexon; (vi) advise relevant OvaScience employees and agents as necessary to facilitate compliance with the obligations of this Section 6.2(c), including advising outside OvaScience patent counsel regarding the obligations of this sentence or any relevant protocols and procedures established by the IPC; and (vii) be solely responsible for all costs and expenses incurred by OvaScience in connection with the preparation, filing, prosecution and maintenance of Patents for Joint Program Inventions. To the extent that OvaScience does not exercise the rights to conduct and direct under the prior sentence (including an abandonment under clause (iv) of the prior sentence), Intrexon shall have the option to assume the preparation, filing, prosecution and maintenance of Patents for Joint Program Inventions at its own discretion and expense, subject to Intrexon providing OvaScience in a timely manner with copies of all material correspondence regarding Joint Program Inventions to and from any foreign or domestic patent offices and patent prosecution counsel (including at a minimum any related drafts of patent applications, official responses, and other substantive communications and filings at least fifteen (15) days prior to any applicable deadline for review) for OvaScience comment and review prior to filing. Intrexon and OvaScience shall reasonably cooperate in connection with such filing, prosecution, and maintenance under this Section 6.2(c), including with respect to executing and submitting and documents necessary to perfect the rights of the Parties.

(d) As used in this Section 6.2(d), “Prosecuting Party” means Intrexon in the case of Intrexon Patents and OvaScience in the case of OvaScience Program Patents and Patents for Joint Program Inventions prosecuted by it pursuant to Section 6.2(c). The Prosecuting Party shall be entitled to use patent counsel selected by it and reasonably acceptable to the non-Prosecuting Party (including in-house patent counsel as well as outside patent counsel) for the prosecution of the Intrexon Patents and OvaScience Program Patents, as applicable. The Prosecuting Party shall:

(i) regularly provide the other Party in advance with reasonable information relating to the Prosecuting Party’s prosecution of Patents hereunder, including by providing copies of substantive communications, notices and actions submitted to or received from the relevant patent authorities and copies of drafts of filings and correspondence that the Prosecuting Party proposes to submit to such patent authorities (it being understood that, to the extent that any such information is readily accessible to the public, the Prosecuting Party may, in lieu of directly providing copies of such information to such other Party, provide such other Party with sufficient information that will permit such other Party to access such information itself directly);

(ii) consider in good faith and consult with the non-Prosecuting Party regarding its timely comments with respect to the same; provided, however, that if, within fifteen (15) days after providing any documents to the non-Prosecuting Party for comment, the Prosecuting Party does not receive any written communication from the non-Prosecuting Party indicating that it has or may have comments on such document, the Prosecuting Party shall be entitled to assume that the non-Prosecuting Party has no comments thereon;

CONFIDENTIAL TREATMENT REQUESTED

(iii) consult with the non-Prosecuting Party before taking any action that would reasonably be expected to have a material adverse impact on the scope of claims within the Intrexon Patents and OvaScience Program Patents, as applicable.

(e) Without limiting the obligations of confidentiality, non-use, and non-disclosure under this Agreement, neither Party shall file any application for Patent that includes the Confidential Information, including data, Inventions, and other Information, of the other Party without the prior written consent of the other Party, or will publish any Confidential Information of another party or make any reference to another party or its intellectual property or materials as used in connection with any Research Project and/or Project Plan without the prior written consent of the other Party.

6.3 Infringement of Patents by Third Parties.

(a) Except as expressly provided in the remainder of this Section 6.3, Intrexon shall have the sole right to take appropriate action against any person or entity directly or indirectly infringing any Intrexon Patent (or asserting that an Intrexon Patent is invalid or unenforceable) (collectively, “Infringement”), either by settlement or lawsuit or other appropriate action.

(b) Notwithstanding the foregoing, OvaScience shall have the first right, but not the obligation, to take appropriate action to enforce Product-Specific Program Patents and/or Patents for Joint Program Inventions against any Infringement that in the reasonable judgment of OvaScience involves, or is reasonably expected to involve, a commercially material amount of allegedly infringing activities in the Field (“Field Infringement”) but not against any allegedly infringing activities in the JV Field, either by settlement or lawsuit or other appropriate action. If OvaScience exercises the foregoing right, (i) Intrexon agrees to be named in any such action if required, and (ii) Ovascience agrees to provide Intrexon with a description of its basis for concluding that such Field Infringement exists. If OvaScience fails to take the appropriate steps to enforce such against any Field Infringement within one hundred eighty (180) days of the date one Party has provided notice to the other Party pursuant to Section 6.3(g) of such Field Infringement, then Intrexon shall have the right (but not the obligation), at its own expense, to enforce such Patents against such Field Infringement, either by settlement or lawsuit or other appropriate action. If Intrexon exercises the foregoing right with respect to Patents for Joint Program Inventions, OvaScience agrees to be named in any such action if required.

(c) With respect to any Field Infringement that cannot reasonably be abated through the enforcement of Patents pursuant to Section 6.3(b) but can reasonably be abated through the enforcement of Intrexon Patent(s) (other than the Product-Specific Program Patents or jointly-owned Patents for Joint Program IP), Intrexon shall be obligated to choose one of the following courses of action: (i) enforce one or more of the applicable Intrexon Patent(s) in a commercially reasonable manner against such Field Infringement, or (ii) [***]. To the extent OvaScience shall be entitled to a share of the Recovery a set forth in Section 6.3(f), Intrexon and OvaScience shall bear the costs and expenses of such enforcement equally. The determination of which Intrexon Patent(s) to assert shall be made by Intrexon in its sole discretion; provided, however, that Intrexon shall consult in good faith with OvaScience on such determination. For

CONFIDENTIAL TREATMENT REQUESTED

the avoidance of doubt, Intrexon has no obligations under this Agreement to enforce any Intrexon Patents against, or otherwise xxxxx, any Infringement that is not a Field Infringement.

(d) In the event a Party pursues an action under this Section 6.3, the other Party shall reasonably cooperate with the enforcing Party with respect to the investigation and prosecution of any alleged, threatened, or actual Infringement, at the enforcing Party’s expense (except with respect to an action under Section 6.3(c), where all costs and expenses will be shared equally in accordance with terms thereof).

(e) OvaScience shall not settle or otherwise compromise any action under this Section 6.3 in a way that diminishes the rights or interests of Intrexon outside the Field (or in the JV Field) or adversely affects any Intrexon Patent (including any rights in a Patent for Joint Program Inventions) without Intrexon’s prior written consent, which consent shall not be unreasonably withheld. Intrexon shall not settle or otherwise compromise any action under this Section 6.3 in a way that diminishes the rights or interests of OvaScience in the Field or adversely affects any Intrexon Patent (including any rights in a Patent for Joint Program Inventions) with respect to the Field without OvaScience’s prior written consent, which consent shall not be unreasonably withheld.

(f) Except as otherwise agreed to by the Parties in writing, any settlements, damages or other monetary awards recovered pursuant to a suit, proceeding, or action brought pursuant to Section 6.3 will be allocated first to the costs and expenses of the Party controlling such action, and second, to the costs and expenses (if any) of the other Party (to the extent not otherwise reimbursed), and any remaining amounts (the “Recovery”) will be shared by the Parties as follows: In any action initiated by Intrexon pursuant to Section 6.3(a) that does not involve Field Infringement, or in any action initiated by Intrexon pursuant to Section 6.3(b), Intrexon shall retain one hundred percent (100%) of any Recovery. In any action initiated by OvaScience pursuant to Section 6.3(b), OvaScience shall retain one hundred percent (100%) of any Recovery, but such Recovery shall be shared with Intrexon as Net Sales. In any action initiated by Intrexon or OvaScience pursuant to Section 6.3(c), [***].

(g) OvaScience shall promptly notify Intrexon of any suspected, alleged, threatened, or actual Infringement of which it becomes aware, and Intrexon shall promptly notify OvaScience of any suspected, alleged, threatened, or actual Field Infringement of which it becomes aware.

CONFIDENTIAL TREATMENT REQUESTED

(a) was already known to the receiving Party and can be demonstrated by written records, other than under an obligation of confidentiality, at the time of disclosure by the other Party;

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

For such reports, publications, and presentations, the disclosing Party will provide the other Party at least fifteen (15) calendar days for review of the proposed submission or presentation. In the case of a Form 8-K filing, such shall be provided to the non-filing Party by the filing party as soon as practicable prior to filing for review and comment. For reports and manuscripts, the disclosing Party will provide the other Party at least thirty (30) days for review of the report or manuscript. The presenting Party will act in good faith to incorporate the comments of the other Party and shall, in any event, redact any Confidential Information of the other Party and cooperate with the other Party to postpone such submissions or presentations if necessary to provide the other Party with sufficient time to prepare and file any related Patent applications before the submission or presentation occurs, as appropriate.

7.4 Terms of the Agreement. Each Party shall treat the terms of this Agreement as the Confidential Information of other Party, subject to the exceptions set forth in Section 7.2.

ARTICLE 11

DISPUTE RESOLUTION

11.1 Disputes. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. In the event of any disputes, controversies or differences which may arise between the Parties out of or in relation to or in connection with this Agreement (other than disputes arising from a Committee), 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 thirty (30) days following the written request for discussions, either Party may then invoke the provisions of Section 11.2. For the avoidance of doubt, any disputes, controversies or differences arising from a Committee pursuant to Article 2 shall be resolved solely in accordance with Section 2.4.

11.2 Arbitration. Any dispute, controversy, difference or claim which may arise between the Parties and not from a Committee, 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) that is not resolved pursuant to Section 11.1 shall, subject to Section 11.10, be settled by binding “baseball arbitration” as follows. Either Party, following the end of the thirty (30) day period referenced in Section 11.1, 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 fifteen (15) 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 ten (10) days of their appointment a third arbitrator meeting the foregoing criteria. Within fifteen (15) 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)

CONFIDENTIAL TREATMENT REQUESTED

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 fifteen (15) 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 11.2; 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 sixty (60) 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.

11.3 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.

11.4 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 11.2 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 11, 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.

11.5 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.

11.6 Injunctive Relief. Nothing in this Article 11 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. Specifically, the Parties agree that a material breach by either Party of its obligations in Section 3.5 or Article 7 of

CONFIDENTIAL TREATMENT REQUESTED

this Agreement may cause irreparable harm to the other Party, for which damages may not be an adequate remedy. Therefore, in addition to its rights and remedies otherwise available at law, including, without limitation, the recovery of damages for breach of this Agreement, upon an adequate showing of material breach of such Section 3.5 or Article 7, and without further proof of irreparable harm other than this acknowledgement, such non-breaching Party shall be entitled to seek (a) immediate equitable relief, specifically including, but not limited to, both interim and permanent restraining orders and injunctions, without bond, and (b) such other and further equitable relief as the court may deem proper under the circumstances. For the avoidance of doubt, nothing in this Section 11.6 shall otherwise limit a breaching Party’s opportunity to cure a material breach as permitted in accordance with Section 10.2.

11.7 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.

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

11.9 Jurisdiction. For the purposes of this Article 11, the Parties acknowledge their diversity and agree to accept the jurisdiction of any United States District Court located in New York for the purposes of enforcing or appealing any awards entered pursuant to this Article 11 and for enforcing the agreements reflected in this Article 11 and agree not to commence any action, suit or proceeding related thereto except in such courts.

11.10 Patent Disputes. Notwithstanding any other provisions of this Article 11, and subject to the provisions of Section 6.2, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Intrexon Patents shall be submitted to a court of competent jurisdiction in the country in which such Patent was filed or granted.

ARTICLE 12

This Agreement may not be modified or amended except in a writing signed by a duly authorized representative of each Party.

12.8 Non-assignability; Binding on Successors. Any attempted assignment of the rights or delegation of the obligations under this Agreement shall be void without the prior written consent of the non-assigning or non-delegating Party; provided, however, that either Party may assign its rights or delegate its obligations under this Agreement without such consent (a) to an Affiliate of such Party or (b) to its successor in interest in connection with any merger, acquisition, consolidation, corporate reorganization, or similar transaction, or sale of all or substantially all of its assets to which this Agreement relates, provided that such assignee agrees in writing to assume and be bound by the assignor’s obligations under this Agreement.
