formation, agree on which Party shall have the authority to finally resolve a dispute that is not resolved pursuant to Section 2.4 above.

(g) 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 his or her respective Party and obtains any advance approvals, delegations, or other authorizations from his or her respective Party in advance of making any Committee votes. Any Committee representative shall only be able to bind his or her respective appointing Party via any Committee vote or other material Committee activity to the extent such vote or other activity has been previously approved by the Party, is within the authority duly delegated to the representative by the respective Party, or is otherwise authorized by its respective Party as may be required by that Party’s corporate charter or bylaws, or by its board of directors. Any action or vote taken without valid authority shall be considered null and void and shall be without effect unless subsequently approved by a vote in accord with this Section 2.5.

2.6 Expansion of the Field.

(a) Intrexon recognizes that Histogenics may during the Program wish to expand the Field beyond the treatment and/or repair of damaged articular hyaline cartilage to the treatment and/or repair of other types of damaged cartilage in humans.

(b) During the Term up to and including the fifth (5^th) anniversary of the Effective Date, Intrexon agrees that it shall first provide Histogenics with the ability to negotiate with Intrexon (who shall act in good faith) for 90 days regarding amendment to this Agreement so as to expand the Field to include the treatment and/or repair of any and all types of damaged cartilage excluding the spine in humans before Intrexon grants any conflicting rights under the Intrexon IP to any Third Party. If after such good faith negotiations the Parties are unable to come to mutually agreeable terms regarding an expansion of the Field under the prior sentence with respect to the applicable type of damaged cartilage in humans (other than articular hyaline cartilage), Intrexon’s obligations under this Section 2.6(b) will be deemed fulfilled with respect to such type of damaged cartilage and Intrexon shall thereafter have no further obligation to first negotiate with Histogenics.

(c) Additionally at any time during the Term, Intrexon shall, upon reasonable request from Histogenics, engage in good faith negotiations with respect to expansion of the Field to the treatment and/or repair of any type of damaged cartilage in humans other than articular hyaline cartilage. For clarity, the right of Histogenics to request such negotiations under this Section 2.6(c) does not obligate Intrexon to reserve any area of collaboration outside the

conditioned or delayed, Intrexon Materials that are or express ingredients for the Collaboration Product sublicensed by the Product Sublicensee to a Third Party contractor performing on behalf of that Product Sublicensee contract manufacturing responsibilities for Collaboration Products, and may in connection therewith grant limited sublicenses to the extent necessary to enable such Third Party to perform such activities. Histogenics will require and ensure that if any Product Sublicensee transfers any Intrexon Materials under this Section 3.2(a), that such Product Sublicensee will take commercially reasonable steps, including contractually obligating any such Third Party contractors, to ensure that the rights of Intrexon in and to the Intrexon Materials and Intrexon IP and under the provisions of Articles 6 and 7 of this Agreement are not violated by any Third Party contractors of such Product Sublicensees.

(b) Histogenics may, (i) without Intrexon’s written consent, sublicense the rights granted under Section 3.1 to an Affiliate that is a wholly-owned subsidiary of Histogenics, transfer the Intrexon Materials to such Affiliate, and/or grant such Affiliate the right to display the Intrexon Trademarks and (ii) with Intrexon’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed, sublicense the rights granted under Section 3.1 to an Affiliate that is not a wholly-owned subsidiary of Histogenics, transfer the Intrexon Materials to such Affiliate, and/or grant such Affiliate the right to display the Intrexon Trademarks. In the event of any such grant or transfer to an Affiliate, Histogenics shall remain responsible for, and be guarantor of, the performance by any such Affiliate and shall cause such Affiliate to comply with the provisions of this Agreement in connection with such performance (as though such Affiliate were Histogenics), including any payment obligations owed to Intrexon hereunder.

(c) Histogenics may grant a sublicense of the rights granted under Section 3.1 (and not including a right to sublicense under this Section 3.1(c)) without Intrexon’s written consent to a Third Party licensee of any Collaboration Product that would qualify as a Retained Product under any of the criteria set forth in Section 10.4 (a) (a “Product Sublicensee”), to the extent necessary to permit such Third Party to obtain regulatory approval for, research, develop, use, import, export, make, have made, sell, offer for sale, and otherwise Commercialize and exploit that Collaboration Product (a “Product Sublicense”), provided, that (i) such Product Sublicense is expressly limited to the appropriate Collaboration Product, (ii) such Product Sublicense does not grant the Product Sublicensee any rights to Intrexon IP other than as incorporated into the Collaboration Product at the time of the Product Sublicense, (iii) such Product Sublicense does not purport to relieve Histogenics of any of its obligations under this Agreement, (iv) the Product Sublicensee agrees in writing, to which Intrexon is an express third party beneficiary, to abide by provisions consistent with the following provisions of this Agreement: Sections 3.1, 3.3, 3.4, 3.6, 3.8, 3.10, and 3.11 and Articles 6, 7, and 10, (v) the Product Sublicense is summarized to the JSC by Histogenics before execution by Histogenics and the prospective Product Sublicensee and as soon as is reasonably practical for the purpose of allowing the JSC to review and comment upon the terms and scope of the Product Sublicense agreement before execution and (vi) the Product Sublicense does not include any “Bundling”. For the purposes of this Section, “Bundling” is a situation in which all three of the following exist: (A) the offering by Histogenics or its Affiliates to a Third Party, or by a Third Party to Histogenics or its Affiliates, of any rights, goods or services with respect to a Collaboration Product (including sale of Collaboration Product itself); (B) the offering by Histogenics or its Affiliates to a Third Party, or by a Third Party to Histogenics or its Affiliates, of any other rights, goods or services (including any rights, goods or services relating to other products Histogenics

15

or any of its Affiliates Controls, sells or otherwise disposes of); and (C) the consideration for the rights, goods or services in such offering is less than would have been customarily accepted by Histogenics, or more than would have been customarily provided by Histogenics, if such rights, goods or services were offered individually (i.e., separate from the bundle).

In addition, Histogenics may grant a sublicense of the rights granted under Section 3.1 (and not including a right to sublicense under this Section 3.1(c)), without Intrexon’s written consent, but only with respect to ****, to ****, of any Collaboration Product that would qualify as a Retained Product under any of the criteria set forth in Section 10.4 (a), to the extent necessary to permit such Third Party to obtain regulatory approval for, research, develop, use, import, export, make, have made, sell, offer for sale, and otherwise Commercialize and exploit that Collaboration Product in ****, provided, that Histogenics meets the requirements of (i) through (v) in the paragraph immediately above.

3.3 Limitation on Sublicensees. None of the enforcement rights under the Intrexon Patents that are granted to Histogenics pursuant to Section 6.3 shall be transferred to, or exercised by, a Sublicensee except with Intrexon’s prior written consent, which may be withheld in Intrexon’s sole discretion.

3.4 No Non-Permitted Use. Histogenics hereby covenants that it shall not, nor shall it permit any Affiliate or, if applicable, (sub)licensee, to use or practice, directly or indirectly, any Intrexon IP, Intrexon Channel Technology, or Intrexon Materials for any purposes other than those expressly permitted by this Agreement.

3.5 Exclusivity. Neither Intrexon nor its Affiliates shall make the Intrexon Channel Technology, Intrexon IP or Intrexon Materials available to any Third Party for the purpose of developing or Commercializing products in the Field (except as set forth in a JSC approved work plan), and neither Intrexon nor any Affiliate shall pursue (either by itself or with a Third Party or Affiliate) the research, development or Commercialization of any product for purpose of commercial use or sale in the Field, outside of the Program. Further, neither Histogenics nor its Affiliates who are wholly-owned subsidiaries of Histogenics shall pursue (either by itself or with a Third Party or Affiliate) outside of the Program the utilization of any synthetic biology platform in conjunction with a Universal Cell Line for the research, development or Commercialization of any product for purpose of commercial use or sale in the Field where such products would compete with Collaboration Products.

3.6 Off Label Use. For purposes of clarity, (a) the use by direct or indirect purchasers or other users of Collaboration Products outside the Field (commonly referred to as “off label use”) shall not constitute a breach by Histogenics of the terms of Article 3, provided that neither Histogenics nor its Affiliate (nor any Third Party under contract with either of them) marketed or promoted Collaboration 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 Article 3, 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.

reasonably cooperate with Histogenics to provide Histogenics with such waivers, cross reference letters, assignments, and/or other reasonable documentation as may be necessary or useful for Histogenics’ full exercise of its right of access under this paragraph. To the extent that any such data, reports, filings or communications in this 3.8(b) contain Confidential Information such information shall be subject to the provisions of Article 7.

3.9 Third Party Licenses.

(a) **** shall obtain, ****, any licenses from Third Parties that are required in order to practice the Intrexon Channel Technology in the Field where the licensed intellectual property is reasonably necessary for **** to conduct genetic and cell engineering and related analytic activities under JSC established plans for the Program (but specifically excluding intellectual property directed to any specific target genes selected by the JSC for inclusion into the Universal Cell Line) (“Supplemental In-Licensed Third Party IP”). Other than with respect to Supplemental In-Licensed Third Party IP, **** shall be solely responsible for obtaining, ****, any licenses from Third Parties that **** determines, in its sole discretion, are required in order to lawfully make, use, sell, offer for sale, or import Collaboration Products (“Complementary In-Licensed Third Party IP”). Supplemental In-Licensed Third Party IP and Complementary In-Licensed Third Party IP are collectively referred to as “In-Licensed Program IP”.

(b) In the event that either Party desires to license from a Third Party any Supplemental In-Licensed Third Party IP or Complementary In-Licensed Third Party IP, such Party shall so notify the other Party, and the IPC shall discuss such In-Licensed Program IP and its applicability to the Collaboration Products and to the Field. As provided above in Section 3.8(a), **** shall have the sole right and responsibility to pursue a license under Supplemental In-Licensed Third Party IP, and **** hereby covenants that it shall not itself directly license such Supplemental In-Licensed Third Party IP at any time, provided that **** may (but shall not be obligated to) obtain such a license directly if the Third Party owner or licensee of such Supplemental In-Licensed Third Party IP brings an infringement action against **** or its Affiliates or threatens to bring such action (including, without limitation, if such threats would reasonably be considered to subject the Third Party owner or licensee to declaratory judgment jurisdiction) and, after written notice to **** of such action, **** fails to obtain a license to such Supplemental In-Licensed Third Party IP using Diligent Efforts within ninety (90) days after such notice. Following the IPC’s discussion of any Complementary In-Licensed Third Party IP, subject to Section 3.8(c), **** shall have the right to pursue a license under Complementary In-Licensed Third Party IP, at **** sole expense. For the avoidance of doubt, **** may at any time obtain a license under Complementary In-Licensed Third Party IP outside the Field, at **** sole expense, provided that if **** decides to seek to obtain such a license, it shall use reasonable efforts to coordinate its licensing activities in this regard with ****.

(c) **** shall provide the proposed terms of any license under Complementary In-Licensed Third Party IP and the final version of the definitive license agreement for any Complementary In-Licensed Third Party IP to the IPC for review and discussion prior to signing, and shall consider **** comments thereto in good faith. To the extent that **** obtains a license under Supplemental In-Licensed Third Party IP,

CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL

**** shall provide the final version of the definitive license agreement for such Supplemental In-Licensed Third Party IP to the IPC. If **** acquires rights under any Supplemental In-Licensed Third Party Program IP outside the Field, it will do so on a non-exclusive basis unless it obtains the prior written consent of Intrexon for such license outside the Field to be exclusive. Any Party that is pursuing a license to any In-Licensed Program IP with respect to the Field under this Section 3.8 shall keep the other Party reasonably informed of the status of any negotiations relating thereto. For purposes of clarity, (i) any costs incurred by **** in obtaining and maintaining licenses to Supplemental In-Licensed Third Party IP shall be borne solely by ****, and (ii) any costs incurred by **** in obtaining and maintaining licenses to Complementary In-Licensed Third Party IP (and, to the limited extent provided in subsection (b), Supplemental In-Licensed Third Party IP) shall be borne solely by ****.

(d) For any Third Party license under which **** or its Affiliates who are wholly-owned subsidiaries of **** obtain a license under Patents claiming inventions or know-how specific to or used or incorporated into the development, manufacture, and/or Commercialization of Collaboration Products, **** shall use commercially reasonable efforts to ensure that **** will have the ability, to the extent required by ****, to assign such agreement to **** or grant a sublicense to **** thereunder (having the scope set forth in ****).

(e) The licenses granted to Histogenics under Section 3.1 may include sublicenses under Intrexon IP that has been licensed to Intrexon by one or more Third Parties. Any such sublicenses are subject to the terms and conditions set forth in the applicable upstream license agreement, subject to the cost allocation set forth in Section 3.9(c), provided that Intrexon shall either provide unredacted copies of such upstream license agreements to Histogenics or shall disclose in writing to Histogenics all of such terms and conditions that are applicable to Histogenics, in each case prior to or on the date on which the sublicense takes effect. Histogenics shall not be responsible for complying with any provisions of such upstream license agreements unless, and to the extent that, such provisions have been disclosed to Histogenics as provided in the preceding sentence.

(f) If either Party receives written notice from a Third Party concerning activities of a Party taken in conjunction with performance of obligations under this Agreement, which notice alleges infringement by a Party of, or offers license under, Patents or other intellectual property rights owned or controlled by that Third Party, the receiving Party shall inform the other Party thereof within five (5) business days.

3.10 Licenses to Intrexon. Subject to the terms and conditions of this Agreement, Histogenics hereby grants to Intrexon a non-exclusive, worldwide, fully-paid, royalty-free license, under any applicable Patents or other intellectual property Controlled by Histogenics or its Affiliates who are wholly-owned subsidiaries of Histogenics, solely to the extent necessary for Intrexon to conduct those responsibilities assigned to it under this Agreement, which license shall be sublicensable solely to Intrexon’s Affiliates or to any Intrexon subcontractors as permitted in accord with Section 4.5 or as otherwise permitted to be used by Intrexon in conjunction with support services under Section 4.6 (Subject to JSC research plan approval).

imposed on Intrexon under this Agreement. Any breach of any such obligations by any Affiliate or subcontractor shall be deemed a breach by Intrexon of its obligations under this Agreement, and Intrexon shall be responsible and liable for any breach of any such obligations by any of its Affiliates or subcontractors.

3.11 Restrictions Relating to Intrexon Materials. Histogenics and its permitted sublicensees shall use the Intrexon Materials solely for purposes of the Program and not for any other purpose without the prior written consent of Intrexon. With respect to the Intrexon Materials comprising Intrexon’s vector assembly technology, Histogenics shall not, and shall ensure that Histogenics personnel and permitted sublicensees do not, except as otherwise permitted in this Agreement (a) distribute, sell, lend or otherwise transfer such Intrexon Materials to any Third Party; (b) co-mingle such Intrexon Materials with any other proprietary biological or chemical materials without Intrexon’s written consent; or (c) analyze such Intrexon Materials or in any way attempt to reverse engineer or sequence such Intrexon Materials.

ARTICLE 4

OTHER RIGHTS AND OBLIGATIONS

4.1 Development and Commercialization. Subject to Sections 4.5 and 4.6, Histogenics shall be solely responsible for the development and Commercialization of Collaboration Products. Histogenics shall be responsible for all costs incurred in connection with the Program except that Intrexon shall be responsible for the following: (a) if applicable, costs of establishing manufacturing capabilities and facilities in connection with Intrexon’s manufacturing obligation under Section 4.5 (provided, however, that Intrexon may include an allocable portion of such costs, through depreciation and amortization, when calculating the Fully Loaded Cost of manufacturing the applicable portion of a Collaboration Product, to the extent such allocation, depreciation, and amortization is permitted by US GAAP, it being recognized that the majority of non-facilities scale-up costs cannot be capitalized and amortized under US GAAP); (b) costs of basic research with respect to the Intrexon Channel Technology and Intrexon Materials (i.e., platform improvements) but, for clarity, excluding research described in Section 4.6 or research requested by the JSC for the development of a Collaboration Product (which research costs shall be reimbursed by Histogenics); (c) ****; (d) costs of filing, prosecution and maintenance of Intrexon Patents; and (e) any other costs mutually agreed upon by the Parties in writing as being Intrexon’s responsibility.

and explanations of any material deviations, significant developments in the development and/or Commercialization of the Collaboration Products, including initiation or completion of a regulatory trial, submission of a United States or international regulatory filing, receipt of a response to such United States or international regulatory filing, product safety event, receipt of regulatory approval, or commercial launch, and manufacturing costs and pricing information. As set forth in Section 3.8 above, Histogenics shall also provide to Intrexon copies of all final regulatory documents and reports, and regulatory correspondence and filings generated by Histogenics, to the extent that they relate specifically to Intrexon Materials that are or express ingredients for Collaboration Products, as soon as practical following receipt of Intrexon’s written request for such materials. Intrexon will keep Histogenics informed about Intrexon’s efforts to undertake discovery-stage research for the Program with respect to the Intrexon Channel Technology and Intrexon Materials. Unless otherwise provided herein or directed by the JSC, such disclosures by Histogenics and Intrexon will be coordinated by the JSC and made in connection with JSC meetings at least once every six (6) months while Collaboration Products are being developed or Commercialized anywhere in the world, and shall be reflected in the minutes of such meetings.

4.3 Regulatory Matters. At such time as the JSC authorizes the initiation of active regulatory activities for Collaboration Products, the RAC shall be formed and constituted to actively manage such regulatory activities. Histogenics shall thereafter own and maintain, at its own cost, all regulatory filings and regulatory approvals for Collaboration Products that Histogenics is developing or Commercializing pursuant to this Agreement. As such, Histogenics shall be responsible for reporting all adverse events related to such Collaboration Products to the appropriate regulatory authorities in the relevant countries, in accordance with the applicable laws and regulations of such countries. To the extent that Intrexon will itself develop, or in collaboration with other third parties develop, Intrexon Materials outside of the Field, Intrexon may request that Histogenics and Intrexon establish and execute a separate safety data exchange agreement, which agreement will address and govern the timely exchange of safety information generated by Histogenics, Intrexon, and relevant third parties with respect to specific Intrexon Materials.

4.4 Diligence.

(a) Histogenics shall use, and shall require its sublicensees to use, Diligent Efforts to develop and Commercialize Collaboration Products in accordance with plans for projects mutually agreed upon by the parties through the JSC.

(b) Without limiting the generality of the foregoing, Intrexon may, from time to time, notify Histogenics via the JSC that it believes it has identified a Superior Therapy, and in such case Intrexon shall provide to Histogenics its then-available information about such product and reasonable written support for its conclusion that the product constitutes a Superior Therapy. Promptly thereafter, Histogenics and Intrexon shall discuss and come to a mutual agreement regarding one or more tests that will be conducted to try to validate Intrexon’s conclusion that the product constitutes a Superior Therapy. If the parties mutually agree that Intrexon’s conclusion is validated by such test(s), then Histogenics shall have the following obligations with respect to such proposed Superior Therapy: (i) within sixty (60) days after such notification, Histogenics shall prepare and deliver to the JSC for review and approval a development plan

21

CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL

detailing how Histogenics will pursue the Superior Therapy (including a proposed budget); (ii) Histogenics shall revise the development plan as directed by the JSC; and (iii) following approval of the development plan by the JSC, Histogenics shall use Diligent Efforts to pursue the development of the Superior Therapy under the Program in accordance with such development plan. If Histogenics fails to comply with the foregoing obligations, or if Histogenics 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, then Intrexon shall have the termination right set forth in Section 10.2(c) (Subject to the limitation set forth therein). For clarity, any dispute arising under this 4.4, including any dispute as to whether a proposed project 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 Histogenics’ Affiliates and any permitted sublicensees shall be attributed to Histogenics for the purposes of evaluating Histogenics’ fulfillment of the obligations set forth in this Section 4.4.

4.5 Manufacturing. The JSC will determine the strategy for manufacturing of the Collaboration Product giving due consideration to the concerns of either Party regarding the protection of its proprietary Information (including know-how, trade secrets, and Confidential Information) and other intellectual property rights (including Patents, trademarks, and biomaterials). Intrexon shall have the option to propose to the JSC that Intrexon should perform (or have its preferred contract manufacturer perform) relevant manufacturing activities in connection with a Collaboration Product to the extent that such activities may be reasonably expected to materially impact Intrexon’s rights in and to Intrexon Channel Technology, Intrexon IP, and Intrexon Materials. To the extent that Intrexon so proposes under this Section 4.5, Histogenics, if it consents to such proposal, such consent not to be unreasonably withheld, may request that the Parties establish 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 the relevant materials of the Parties. Any manufacturing Information or Intrexon Materials transferred hereunder to Histogenics or its contract manufacturer shall not be further transferred to any Third Party, including any sublicensee (including a Product Sublicensee), or any Histogenics Affiliate without the prior written consent of Intrexon, except as otherwise permitted under Section 3.2 and provided, however, that Intrexon shall not unreasonably withhold such consent.

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 Histogenics for the research and development of Collaboration Products under the Program, which initial Work Plan may be amended from time to time by the JSC. The Work Plan shall set forth activities to be undertaken by Intrexon in support of development of Collaboration Products,

22

CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL

deliverables, timelines, and estimated costs (including a detailed budget that shall include all estimated Fully Loaded Costs). Additionally, from time to time, on an ongoing basis, Histogenics may request, or Intrexon may propose, that Intrexon perform certain additional support services with respect to researching and developing new Collaboration Products or improving the manufacturing or processing methods for any existing Collaboration Products. To the extent that Intrexon perform such support services under this Section 4.6(a) that are requested by Histogenics and/or approved by the JSC, it is understood that Intrexon would be compensated for such services in cash payments from Histogenics based upon Intrexon’s Fully Loaded Cost in connection with such services as set forth in Section 4.6(b).

(b) Prior to achievement of the IND Acceptance Milestone Event, Histogenics will compensate Intrexon for such support services under this Section 4.6 with cash equal to fifty percent (50%) of Intrexon’s invoiced Fully Loaded Cost in connection with such services. Within ninety (90) days of achievement of the first instance of the IND Acceptance Milestone Event, Histogenics shall pay Intrexon an additional (i.e., a second) fifty percent (50%) of Intrexon’s prior invoiced Fully Loaded Cost in connection with such services (i.e., such that Intrexon will have in total been compensated for one hundred percent (100%) of the Fully Loaded Costs that were invoiced prior to the first occurrence of the IND Acceptance Milestone Event), with cash. Following the first achievement of the IND Acceptance Milestone Event, unless otherwise agreed upon by the parties, Histogenics will thereafter compensate Intrexon for such support services under this Section 4.6 with cash payments equal to one hundred percent (100%) of Intrexon’s invoiced Fully Loaded Cost in connection with such services.

(c) Under this Section 4.6, Intrexon shall keep the JSC reasonably apprised of any expected material deviations from budgeted costs under JSC-approved research projects and Work Plans as such deviations arise and/or as Intrexon becomes aware of the threat of such deviation, provided that in no event will Intrexon provide Histogenics with a report of budgeted costs to actual costs on such projects and Work Plans less frequently than once per calendar year. In the event that, in performance under a JSC-approved project or Work Plan is projected to exceed more than **** of the amount budgeted or Intrexon reasonably determines that the JSC-established budget is insufficient to complete performance of the tasks under the project, it will notify the JSC such that the JSC can appropriately amend the respective project or Work Plan and Intrexon may discontinue performance under such project plan until the JSC has so amended the project or Work Plan.

4.7 Compliance with Law. Each Party shall comply, and shall ensure that its Affiliates, (sub)licensees and Third Party contractors comply, with all applicable laws, regulations, and guidelines applicable to the Program, including without limitation those relating to the transport, storage, and handling of Intrexon Materials and Collaboration Products.

4.8 Trademarks and Patent Marking. To the extent Histogenics elects to use Intrexon Trademarks in connection with Collaboration Products and to the extent permitted by applicable law and regulations, Histogenics shall ensure that the packaging, promotional materials, and labeling for Collaboration Products, as appropriate, shall carry, in a conspicuous location, the applicable Intrexon Trademark(s), subject to Histogenics’ reasonable approval of the size, position, and location thereof. Consistent with the U.S. patent laws, Histogenics shall ensure that Collaboration Products, or their respective packaging or accompanying literature as

appropriate, bear applicable and appropriate patent markings for Intrexon Patent numbers. Histogenics shall provide Intrexon with copies of any materials containing the Intrexon Trademarks or such patent markings prior to using or disseminating such materials, in order to obtain Intrexon’s approval thereof, which approval shall not be unreasonably withheld, conditioned or delayed. Histogenics’ use of the Intrexon Trademarks and patent markings shall be subject to prior review and approval of the IPC. Histogenics acknowledges Intrexon’s sole ownership of the Intrexon Trademarks and agrees not to take any action inconsistent with such ownership. Histogenics covenants that it shall not use any trademark confusingly similar to any Intrexon Trademarks in connection with any products (including any Collaboration Product). From time to time during the Term, Intrexon shall have the right to obtain from Histogenics samples of Collaboration Product sold by Histogenics or its Affiliates or Sublicensees, or other items which reflect public uses of the Intrexon Trademarks or patent markings, solely for the purpose of inspecting the quality of such Collaboration Products, the use of the Intrexon Trademarks, or the accuracy of the patent markings. In the event that Intrexon inspects under this Section 4.8, Intrexon shall notify the result of such inspection to Histogenics in writing promptly thereafter. Histogenics shall comply with reasonable policies provided by Intrexon in writing from time-to-time at least thirty (30) days prior to the due date of the obligation to comply to maintain the goodwill and value of the Intrexon Trademarks.

4.9 Equity Purchase Commitment.

(a) Subject to Section 4.9(b), if requested by Histogenics, Intrexon will participate in a Qualified Financing (as hereinafter defined) conducted by Histogenics and will purchase as part of, or in connection with, such Qualified Financing, $15,000,000 worth of Common Stock or other securities issued and sold by Histogenics in the Qualified Financing (the “Equity Purchase Commitment”), provided, however, that in no event shall Intrexon have any obligation to purchase more than that number of shares that, together with any other shares of Common Stock held by Intrexon, results in Intrexon’s aggregate ownership of Histogenix’s Common Stock following the Qualified Financing equaling or exceeding 25% of the outstanding Common Stock of Histogenics. For the purposes of this Section 4.9, a “Qualified Financing” shall mean a sale by Histogenics of Common Stock or equity securities convertible into Common Stock in an underwritten public offering raising gross proceeds of at least $50,000,000, including the Equity Purchase Commitment. The price per share paid by Intrexon in any such Qualified Financing shall be the same as that paid by the other investors in such Qualified Financing, and Intrexon shall receive securities of the same type and with the same rights, preferences and privileges as the other investors in such Qualified Financing, including, for example, any warrant coverage, subject to the execution by Intrexon of the investment documents entered into by the other investors in the Qualified Financing. Notwithstanding the foregoing, in the event that counsel to Histogenics or counsel to any underwriter in the Qualified Financing advises Histogenics that such participation is not permissible under and in compliance with applicable securities laws (including without limitation Section 5 of the Securities Act of 1933, as amended (the “Securities Act”)):

(i) Intrexon shall be under no obligation to participate in such public offering but may, upon receipt of the prospectus and other offering documents prepared by Histogenics in connection with such public offering, at its election, do so in an amount equal to

24

CONFIDENTIAL TREATMENT REQUESTED

the Equity Purchase Commitment. Upon such election, Histogenics shall permit Intrexon to participate in such public offering in the amount of the Equity Purchase Commitment.

(ii) In the event that Intrexon elects, in accordance with Section 4.9(a)(i), not to participate in a public offering, Intrexon shall be obligated to purchase an amount equal to the Equity Purchase Commitment in a private placement and not in such public offering. In any such private placement: (A) the offer of the securities in such private placement shall be made on the same terms and conditions as the offer of the securities in the public offering, (B) the closing of the private placement shall occur concurrently with the closing of the public offering, and (C) Histogenics shall provide registration rights in a form similar to those set forth in the Form of Equity Terms under the heading “Registration Rights” with respect to the securities purchased in the private placement.

(b) Notwithstanding the foregoing, Intrexon shall not be obligated to purchase shares of the Company’s Common Stock pursuant to this Section 4.9 unless:

(i) the Company shall then be in substantial compliance with its obligations under this Agreement, and such Agreement shall not have been terminated, and

(ii) the Qualified Financing shall have closed within twelve (12) months following the date of this Agreement.

ARTICLE 5

COMPENSATION

5.1 Technology Access Fee. In partial consideration for Histogenics’ appointment as an exclusive channel collaborator in the Field and the other rights granted to Histogenics hereunder and as an access fee for commercial license rights to the Intrexon IP granted under Section 3.1, Histogenics shall pay to Intrexon a one time payment valued at ten million United States dollars ($10,000,000) (the “Technology Access Fee”). The Technology Access Fee shall be paid in the form of the Note executed and delivered by Histogenics on the Effective Date. The receipt by Intrexon of the executed Note for the Technology Access Fee on the Effective Date and compliance by Histogenics with regard to the maturity and payment provisions set forth in the Note are both conditions subsequent to the effectiveness of this Agreement.

5.2 Royalty Payments for Collaboration Products.

(a) No later than thirty (30) days after each calendar quarter in which there is positive aggregate Gross Profit arising from the sale in the Field and Territory of Collaboration Products, Histogenics shall pay to Intrexon **** of the aggregate Gross Profit for such Collaboration Products during such calendar quarter. For purposes of clarity, in the event that there is negative Gross Product for a particular Collaboration Product in any calendar quarter, (i) neither Histogenics nor Intrexon shall owe any payments hereunder with respect to such Collaboration Product and (ii) any such negative Gross Profit that results from Excess Product Liability Costs may be carried forward to future calendar quarters and offset against positive Gross Profit in such future calendar quarters for the same Collaboration Product;

provided, that, except as set forth in the preceding sentence, Histogenics shall not be permitted to carry forward any negative Gross Profit to subsequent quarters.

(b) No later than thirty (30) days after each calendar quarter in which Histogenics or any Histogenics Affiliate receives Sublicensing Revenue, Histogenics shall pay to Intrexon **** of such Sublicensing Revenue.

5.3 Milestones.

(a) Histogenics Commercialization Milestones. Upon certain instances of attainment of certain Commercialization Milestone Events by a Collaboration Product (whether such attainment is achieved by Histogenics or by a permitted sublicensee), Histogenics has agreed to pay Intrexon milestone payments as set forth in this Section 5.3. The milestone payments are each payable, at Histogenics’ election subject to 5.3(b), either in cash or in shares of Histogenics’ common stock (using Fair Market Value to calculate the number of shares to be issued to Intrexon in lieu of cash). The specific milestone payments due to Intrexon upon achievement of the various Commercialization Milestone Events are set forth in Sections 5.3(a)(i) through 5.3(a)(v) below. Each of the Commercialization Milestone Events under Sections 5.3(a)(i) through 5.3(a)(iv) below will trigger payment by Histogenics only once (i.e., only the first time each such Commercialization Milestone Event in question is achieved), and Histogenics will not be obligated to make any milestone payment for any given Collaboration Product if that same milestone payment had been previously paid to Intrexon for any previous Collaboration Product having achieved previously the same Commercialization Milestone Event. The Commercialization Milestone Event under Section 5.3(a)(v) below, however, will trigger payment by Histogenics each time it is achieved.

(i) Histogenics shall pay Intrexon a milestone payment of five hundred thousand United States dollars ($500,000) within thirty (30) days of the first instance of the achievement of the IND Filing Milestone Event, said payment being made, at Histogenics’ option subject to Sections 5.3(b) and 5.3(c), either in cash or in shares of Histogenics’ common stock.

(ii) Histogenics shall pay Intrexon a milestone payment of two million five hundred thousand United States dollars ($2,500,000) within thirty (30) days of the first instance of the achievement of the IND Acceptance Milestone Event, said payment being made, at Histogenics’ option subject to Section 5.3(b) and 5.3(c), either in cash or in shares of Histogenics’ common stock.

(iii) Histogenics shall pay Intrexon a milestone payment of three million United States dollars ($3,000,000) within thirty (30) days of the first instance of the achievement of the Phase III Milestone Event, said payment being made, at Histogenics’ option subject to Section 5.3(b) and 5.3(c), either in cash or in shares of Histogenics’ common stock.

(iv) Histogenics shall pay Intrexon a milestone payment of five million United States dollars ($5,000,000) within thirty (30) days of the first instance of the achievement of the Approval Milestone Event, said payment being made, at Histogenics’ option subject to Section 5.3(b) and 5.3(c), either in cash or in shares of Histogenics’ common stock.

CONFIDENTIAL

(v) Histogenics shall pay Intrexon a milestone payment of one million United States dollars ($1,000,000) within thirty (30) days of each instance of the achievement of the Amended Approval Milestone Event, said payment being made, at Histogenics’ option subject to Section 5.3(b) and 5.3(c), either in cash or in shares of Histogenics’ common stock.

(b) Commercialization Milestones After Company Sale. In the event that Histogenics consummates a Company Sale prior to paying to Intrexon any one or more of the respective milestone payments set forth in Sections 5.3(a)(i) through 5.3(a)(v) and this Agreement is transferred or assigned to the buyer in connection with such Company Sale, then all subsequent payments for Commercialization Milestone Events shall thereafter each be payable only in cash to Intrexon.

(c) Product Sublicense Milestones. If (A) a Commercialization Milestone Event occurs that gives rise to a right for Intrexon to receive a payment from Histogenics under Section 5.3(a), (B) that Commercialization Milestone Event is achieved by a Collaboration Product licensed to a Product Sublicensee under a respective Product Sublicense, and (C) Histogenics is due to receive a milestone payment from the Product Sublicensee for achievement of that same (or substantially similar) Commercialization Milestone Event by the sublicensed Collaboration Product under the respective Product Sublicense, then Intrexon may elect at its own discretion to waive that particular milestone payment from Histogenics for that particular Commercialization Milestone Event and instead designate the amount of the payment due to Histogenics from the Product Sublicensee for acheivement of that same (or substantially similar) Commercializaton Milestone Event as Sublicensing Revenue for which Intrexon will be entitled to receive revenue sharing under Section 5.2(b). If it so elects under this Section 5.3(b), Intrexon must notify Histogenics in writing of its waiver of the specific milestone under the above Section 5.3(a) and its concurrent election to share the milestone payment due from the Product Sublicensee as Sublicensing Revenue at least five (5) business days prior to the deadline for Histogenics to make a payment for the waived milestone payment. The actual receipt by Intrexon of its full share of the Product Sublicensee milestone payment as Sublicensing Revenue will be a condition subsequent to making final any waiver of Intrexon’s rights to receive the respective milestone payment otherwise due from Histogenics under Section 5.3(a). Histogenics will pay Intrexon any amount due under this Section 5.3(b) within the later of (i) thirty (30) days from underlying Commercialization Milestone Event, or (ii) ten (10) days following the date stipulated in the underlying Product Sublicense for Histogenics to receive the milestone payment.

(d) Histogenics Sales Milestones. The Parties additionally agree that the sales based milestones set forth below in Sections 5.3(d)(i) through 5.3(d)(iii) shall be paid by Histogenics to Intrexon. Each milestone shall be payable only once upon the first instance of achievement thereof, and the respective payment for such will be due to be paid to Intrexon within thirty (30) days following the completion of the calendar quarter in which the respective sales milestone was achieved.

(i) Upon the first instance that cumulative annual Net Sales for Collaboration Products reaches three hundred million United States dollars ($300,000,000), Histogenics shall pay Intrexon a milestone payment of five million United States dollars ($5,000,000) within the time frames set forth above.

CONFIDENTIAL

(ii) Upon the first instance that cumulative annual Net Sales for Collaboration Products reaches six hundred and fifty million United States dollars ($650,000,000), Histogenics shall pay Intrexon a milestone payment of seven million five hundred thousand United States dollars ($7,500,000) within the time frames set forth above.

(iii) Upon the first instance that cumulative annual Net Sales for Collaboration Products reaches one billion United States dollars ($1,000,000,000), Histogenics shall pay Intrexon a milestone payment of ten million United States dollars ($10,000,000) within the time frames set forth above.

5.4 Equity Agreement Controls. All issuances of equity interests to Intrexon in accordance with this Agreement shall be in accordance with the terms and conditions of the Note, with regard to the Technology Access Fee, and definitive stock issuance agreements on Histogenics’ standard forms (including standard representaions and warranties of Histogenics and Intrexon), as well as, the Equity Agreement Term.

5.5 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.

5.6 Payment Reports and Records Retention. Within thirty (30) days after the end of each calendar quarter during which, with respect to Collaboration Products, a positive Gross Profit or Sublicensing Revenue have been generated or received, a Commercialization Milestone Event has been achieved, a sales milestone under Section 5.3(d) has been met, or a negative Gross Profit has occurred, Histogenics 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 and Gross Profit, showing all applicable deductions and underlying calculations of COGS;

(c) itemized calculation of Sublicensing Revenue;

(d) the amount of any negative Gross Profit for the applicable calendar quarter, and any negative Gross Profit 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) and 5.2(b);

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

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

28

CONFIDENTIAL TREATMENT REQUESTED

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

For three (3) years after each sale or other commercial use of Collaboration Product, or after incurring any component item Histogenics incorporated into its calculations above, Histogenics shall keep (and shall ensure that its Affiliates and, if applicable, (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.

5.7 Audits.

(a) Upon the written request of Intrexon, Histogenics shall permit an independent certified public accounting firm of internationally recognized standing selected by Intrexon, and reasonably acceptable to Histogenics, to have access to and to review, during normal business hours and upon no less than thirty (30) days prior written notice, the applicable records of Histogenics and its Affiliates to verify the accuracy and timeliness of the reports and payments made by Histogenics under this Agreement. Such review may cover the records for sales made in any calendar year ending not more than three (3) years prior to the date of such request. The accounting firm shall disclose to both Parties whether the royalty reports and/or know-how reports conform to the provisions of this Agreement and/or US GAAP, as applicable, and the specific details concerning any discrepancies. Such audit may not be conducted more than once in any calendar year.

(b) If such accounting firm concludes that additional amounts were owed during such period, Histogenics shall pay additional amounts, with interest from the date originally due as set forth in Section 5.9, within thirty (30) days of receipt of the accounting firm’s written report. If the amount of the underpayment is greater than five percent (5%) of the total amount actually owed for the period audited, then Histogenics 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).

(c) Intrexon shall (i) treat all information that it receives under this Section 5 in accordance with the confidentiality provisions of Article 7 and (ii) cause its accounting firm to enter into an acceptable confidentiality agreement with Histogenics 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.

5.8 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. Histogenics 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 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 Histogenics or the appropriate governmental authority (with the reasonable assistance of Histogenics 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 Histogenics of its obligation to withhold tax, and Histogenics shall apply the reduced rate of withholding tax, or dispense with

29

CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL

withholding tax, as the case may be, provided that Histogenics has received evidence of Intrexon’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least fifteen (15) days prior to the time that the payment is due. If, in accordance with the foregoing, Histogenics 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 forty-five (45) days following that latter payment.

5.9 Late Payments. Any undisputed amount owed by Histogenics 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) two percent (2%) per month, compounded, or (b) the highest rate permitted under applicable law.

design and development of markers, cell processing techniques and lines, complex transgenes and vectors, and production processes, and (B) in any case, that are not based upon and do not incorporate or require the use of the Histogenics Independent IP or Histogenics Patents (collectively, the “Channel-Related Program IP”). For clarity and nothwithstanding the foregoing, the Universal Cell Line and any other cell lines delivered to Histogenics under the Program, and all intellectual property rights therein, shall constitute Channel-Related Program IP and shall therefore be owned by Intrexon. In addition, notwithstanding the first sentence of this Section, all Inventions (together with all Patent rights and other intellectual property rights therein) that (a) relate generally to cell processing techniques and lines, (b) that are not based upon, do not incorporate, or do not require the use of, Intrexon IP, the Intrexon Channel Technology or Intrexon Materials and (c) were invented solely by Histogenics shall be deemed Histogenics Platform Inventions. Histogenics hereby assigns and agrees to assign to Intrexon all of Histogenics’s interests in and to any and all Channel-Related Program IP, and shall perform or have performed any and all acts reasonably necessary to assist Intrexon in perfecting its rights in and to any and all of the Channel-Related Program IP (not including any Histogenics Independent IP that may be included therein), including executing or having executed any documents affecting the appropriate assignment to Intrexon to the extent reasonably requested by Intrexon at Intrexon’s request.

(e) Subject to the foregoing, and excluding Joint Program Inventions, Histogenics shall solely own all right, title and interest in all Inventions (together with all Patent rights and other intellectual property rights therein) that (A) (i) solely relate to use of the Histogenics Independent IP or Histogenics Patents, and (ii) that are not based upon, do not incorporate, or do not require the use of, Intrexon IP, the Intrexon Channel Technology or Intrexon Materials, and/or (B) were invented solely by Histogenics (collectively, “Histogenics Platform Inventions”). Intrexon hereby assigns and agrees to assign to Histogenics all of Intrexon’s interests in and to any and all Histogenics Platform Inventions, and shall perform or have performed any and all acts reasonably necessary to assist Histogenics in perfecting its rights to any and all Histogenics Platform Inventions, including executing or having executed any documents affecting the appropriate assignment to Histogenics to the extent reasonably requested by Histogenics at Histogenics request.

(f) Notwithstanding anything to the contrary in this Agreement, any discovery, invention, process, technique, or other technology, whether or not patentable, that is conceived, and/or reduced to practice by Histogenics solely or jointly through the use of the Intrexon Channel Technology, Intrexon IP, or Intrexon Materials in breach of the terms and conditions of this Agreement, together with all patent rights and other intellectual property rights therein, shall be solely owned by Intrexon and shall be included in the Channel-Related Program IP. Notwithstanding anything to the contrary in this Agreement, any discovery, invention, process, technique, or other technology, whether or not patentable, that is conceived, and/or reduced to practice by Intrexon solely or jointly through the use of the Histogenics Independent IP and/or Histogenics Platform Inventions, in breach of the terms and conditions of this Agreement, together with all patent rights and other intellectual property rights therein, shall be solely owned by Histogenics and shall be included in the Histogenics Platform Inventions.

All Information regarding Histogenics Platform Inventions shall be Confidential Information of Histogenics. Intrexon shall be under appropriate written agreements with each of its employees, contractors, or agents working on the Program, pursuant to which such person shall grant all rights in the Histogenics Platform Inventions to Intrexon (so that Intrexon may convey such rights to Histogenics, as provided herein) and agree to protect all Confidential Information relating to the Program.

(h) Subject to the foregoing clauses of this Section 6.1, all Inventions conceived and/or reduced to practice during the performance of the Program (together with all Patent rights and other intellectual property rights therein) that (i) are neither Channel-Related Program IP nor Histogenics Platform Inventions, and (ii) disclose and/or claim a combination of Intrexon Channel Technology and Histogenics Independent IP (collectively the “Joint Program Inventions”) shall be owned jointly by Intrexon and Histogenics in undivided one-half interests.

(i) For clarity, the Parties’ joint ownership of the Joint Program Inventions does not by itself grant either Party rights in any other intellectual property of the other Party, and, except for the explicit licenses set forth in this Agreement (i) Intrexon is not permitted to use any Histogenics intellectual property (except as may be otherwise expressly granted by Histogenics) in the practice of Joint Program Inventions, and (ii) Histogenics is not permitted to use any Intrexon IP (except as may be otherwise expressly granted by Intrexon) in the practice of Joint Program Inventions. Neither Party shall claim priority to a patent application of the other Party without such other Party’s written consent.

6.2 Patent Prosecution.

(a) Intrexon shall have the sole right, but not the obligation, to conduct and control the filing, prosecution and maintenance of the Intrexon Patents. At the reasonable request of Intrexon, Histogenics shall cooperate with Intrexon in connection with such filing, prosecution, and maintenance, at Intrexon’s expense. Under no circumstances shall Histogenics (i) file, attempt to file, or assist anyone else in filing, or attempting to file, any Patent application, either in the United States or elsewhere, that claims or purports to claim an Invention owned by Intrexon, or (ii) use, attempt to use, or assist anyone else in using or attempting to use, the Intrexon Know-How, Intrexon Materials, or any Confidential Information of Intrexon to support the filing of a Patent application, either in the United States or elsewhere, that contains claims directed to the Intrexon IP, Intrexon Materials, or the Intrexon Channel Technology.

(b) Histogenics shall have the sole right, but not the obligation, to conduct and control the filing, prosecution and maintenance of any Patents claiming Histogenics Platform Inventions (“Histogenics Program Patents”) and any Histogenics Patents. At the reasonable request of Histogenics, Intrexon shall cooperate with Histogenics in connection with such filing, prosecution, and maintenance, at Histogenics’s expense. Under no circumstances shall Intrexon (i) file, attempt to file, or assist anyone else in filing, or attempting to file, any Patent application, either in the United States or elsewhere, that claims or purports to claim an Invention owned by Histogenics, or (ii) use, attempt to use, or assist anyone else in using or attempting to use,

Histogenics Independent IP, Histogenics Platform Inventions, or any Confidential Information of Histogenics to support the filing of a Patent application, either in the United States or elsewhere, that contains claims directed to Histogenics Independent IP or Histogenics Platform Inventions.

(c) The Parties through the IPC shall reasonably cooperate, to the extent such cooperation can be done without substantially compromising any Patents of either Party, to develop a portfolio of Product-Specific Program Patents and Patents for Joint Program Inventions covering relevant Collaboration Products. The Parties shall also reasonably cooperate to conduct and control the filing, prosecution, and maintenance of any applications for patent term extension and/or supplementary protection certificates that may be available as a result of the regulatory approval of any Collaboration Product. Notwhithstanding the foregoing,this Agreement does not require either Party to develop Product-Specific Program Patents and Patents for Joint Program Inventions. During the Term, Intrexon shall have, the first right, but not the obligation, to conduct and direct the filing, prosecution and maintenance of any Patents for Joint Program Inventions consistent with any relevant strategies and determinations set forth by the IPC.

(d) As used in this Section 6.2(d), “Prosecuting Party” means Intrexon in the case of Intrexon Patents, and Histogenics in the case of Histogenics Program Patents. The Prosecuting Party shall be entitled to use patent counsel selected by it (including in-house patent counsel as well as outside patent counsel) for the prosecution of the Intrexon Patents and Histogenics Program Patents, as applicable.

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. Intrexon shall have no right to enforce any Patent owned or Controlled by Histogenics.

(b) Notwithstanding the foregoing, Histogenics shall have the first right, but not the obligation, to take appropriate action to enforce Product-Specific Program Patents against any Infringement that involves a commercially material amount of allegedly infringing activities in the Field (“Field Infringement”), either by settlement or lawsuit or other appropriate action. If Histogenics exercises the foregoing right, Intrexon agrees to be named in any such action if required and to reasonably cooperate with Histogenics with respect to any such action. If Histogenics fails to take the appropriate steps to enforce Product-Specific Program Patents 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 Product-Specific Program Patents against such Field Infringement, either by settlement or lawsuit or other appropriate action.

(c) With respect to any Field Infringement that cannot reasonably be abated through the enforcement of Product-Specific Program Patents pursuant to Section 6.3(b) but can

33

CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL

reasonably be abated through the enforcement of Intrexon Patent(s) (other than the Product-Specific Program Patents), 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 Histogenics shall be entitled to a share of the Recovery as set forth in Section 6.3(f), Intrexon and Histogenics 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 Histogenics on such determination. For the avoidance of doubt, Intrexon has no obligation under this Agreement to enforce any Intrexon Patents against, or otherwise abate, 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) Histogenics 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 adversely affects any Intrexon Patent without Intrexon’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Intrexon shall not settle or otherwise compromise any action under this Section 6.3 in a way that diminishes the rights or interests of Histogenics in the Field or adversely affects any Intrexon Patent with respect to the Field without Histogenics’ prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

(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, Intrexon shall retain one hundred percent (100%) of any Recovery. In any action initiated by Intrexon pursuant to Section 6.3(b), Intrexon shall retain one hundred percent (100%) of any Recovery, but shall share such Recovery with Histogenics as follows: ****. In any action initiated by Histogenics pursuant to Section 6.3(b), Histogenics shall retain one hundred percent (100%) of any Recovery, but shall share such Recovery as follows: ****. No Recovery that is the result of a settlement agreement between Histogenics and a Third Party shall qualify as a Recovery based upon lost profits under the prior sentence unless Histogenics can establish to Intrexon’s reasonable satisfaction that (i) the Recovery is in compensation for an Infringement by such Third Party, (ii) there is a Collaboration Product that is available for Commercial Sale in the relevant jurisdiction(s), (iii) the balance of facts concerning such Infringement and such Collaboration Product are such that they would have more likely than not qualified Histogenics under United States patent laws to

have secured a monetary damages award calculated using a lost profits methodology, and (iv) the size of the Recovery in question is consistent with the size of an damages award that, applying the facts concerning the Subject Infringement and corresponding Collaboration Product, more likely than not would have been awarded using a lost profits methodology under United States patent laws. In any action initiated by Intrexon or Histogenics pursuant to Section 6.3(c), the Parties shall ****.

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

(b) Termination of Licenses. Except as necessary for Histogenics to continue to obtain regulatory approval for, development, use, manufacture, Commercialization of and exploitation of the Retained Products in the Field as permitted by Section 10.4(a), all rights and licenses granted by Intrexon to Histogenics under this Agreement shall terminate and shall revert to Intrexon without further action by either Intrexon or Histogenics. Histogenics’ license with respect to Retained Products shall be exclusive or non-exclusive, as the case may be, on the same terms as set forth in Section 3.1.

(c) Reverted Products. Any products (e.g., a cell line) resulting from the Program that are not Retained Products shall be referred to herein as the “Reverted Products.” Histogenics shall immediately cease, and shall cause its Affiliates and, if applicable, (sub)licensees to immediately cease, all development and Commercialization of the Reverted Products, and Histogenics shall not use or practice, nor shall it cause or permit any of its Affiliates or, if applicable, (sub)licensees to use or practice, directly or indirectly, any Intrexon IP with respect to the Reverted Products. Histogenics shall immediately discontinue making any representation regarding its status as a licensee or channel collaborator of Intrexon with respect to the Reverted Products.

(d) Intrexon Materials. Histogenics shall promptly return, or at Intrexon’s request, destroy, any Intrexon Materials in Histogenics’ possession or control at the time of termination other than any Intrexon Materials necessary for the continued research, development, regulatory approval, use, import, export, manufacture, Commercialization and exploitation of the Retained Products in the Field.

(e) Licenses to Intrexon. Histogenics is automatically deemed to grant to Intrexon, subject to the terms and conditions of this Agreement, a worldwide, fully paid, royalty-free, exclusive (even as to Histogenics and its Affiliates), irrevocable, license (with full rights to Sublicense) under the Histogenics Termination IP, solely to make, have made, import, use, offer for sale and sell Reverted Products in the Field, subject to any exclusive rights held by Histogenics in Reverted Products pursuant to Section 10.4(c). The Parties shall also take such actions and execute such other instruments and documents as may be reasonably necessary to document such license to Intrexon. All other licenses granted by Histogenics to Intrexon under this Agreement shall terminate and shall revert to Histogenics without further action by either Histogenics or Intrexon.

(f) Regulatory Filings. Histogenics shall promptly assign to Intrexon, and will provide full copies of, all regulatory approvals and regulatory filings to the extent that they relate specifically and solely to Reverted Products (if any). Histogenics shall also take such actions and execute such other instruments, assignments and documents as may be reasonably necessary to effect the transfer of rights thereunder to Intrexon. To the extent that there exist any regulatory approvals and regulatory filings that relate both to Reverted Products and other products, Histogenics shall provide copies of the portions of such regulatory filings that relate specifically to Reverted Products and shall reasonably cooperate to assist Intrexon in obtaining the benefits of such regulatory approvals with respect to the Reverted Products.

(g) Data Disclosure. Histogenics shall provide to Intrexon copies of the relevant portions of all material reports and data, including regulatory trial data and reports,

obtained or generated by or on behalf of Histogenics or its Affiliates to the extent that they relate specifically to Reverted Products, within sixty (60) days of such termination unless otherwise agreed, and Intrexon shall have the right to use any such Information in developing and Commercializing Reverted Products and to license any Third Parties to do so.

(h) Third Party Licenses. At Intrexon’s request, Histogenics shall promptly provide to Intrexon copies of all Third Party agreements under which Histogenics or its Affiliates obtained a license under Patents claiming inventions or know-how specific to or incorporated into the development, manufacture and/or Commercialization of the Reverted Products. At Intrexon’s request such that Intrexon may Commercialize the Reverted Products, Histogenics shall promptly work with Intrexon to either, as appropriate (i) with respect to such Third Party agreements relating solely to the applicable Reverted Products and permitting assignment, immediately assign (or cause to be assigned), such agreements to Intrexon, and (ii) with respect to all other such Third Party agreements, Histogenics shall reasonably cooperate to assist Intrexon in obtaining the benefits of such agreements. Thereafter Intrexon shall be fully responsible for all obligations due for its actions under such sublicensed or assigned Third Party agreements. Notwithstanding the above, if Intrexon does not wish to assume any financial or other obligations associated with a particular Third Party agreement identified to Intrexon under this Section 10.4(h), then Intrexon shall so notify Histogenics and Histogenics shall not make such assignment or grant such sublicense (or cause it to be made or granted).

(i) Remaining Materials. At the request of Intrexon, Histogenics shall transfer to Intrexon all quantities of Reverted Product (including final products or work-in-process) in the possession of Histogenics or its Affiliates. Histogenics shall transfer to Intrexon all such quantities of Reverted Products without charge, except that Intrexon shall pay the reasonable costs of processing and shipping.

(j) Third Party Vendors. At Intrexon’s request, Histogenics shall promptly provide to Intrexon copies of all agreements between Histogenics or its Affiliates that are wholly-owned subsidiaries of Histogenics and Third Party suppliers, vendors, or distributors that relate specifically to the supply, sale, or distribution of Reverted Products in the Territory. At Intrexon’s request, Histogenics shall promptly: (i) with respect to such Third Party agreements relating solely to the applicable Reverted Products and permitting assignment, immediately assign (or cause to be assigned), such agreements to Intrexon, and (ii) with respect to all other such Third Party agreements, Histogenics shall reasonably cooperate to assist Intrexon in obtaining the benefits of such agreements. Histogenics shall be liable for any costs associated with assigning a Third Party agreement to Intrexon or otherwise obtaining the benefits of such agreement for Intrexon, to the extent such costs are directly related to Histogenics’ breach. For the avoidance of doubt, Intrexon shall have no obligation to assume any of Histogenics’ obligations under any Third Party agreement.

(k) Commercialization. Intrexon shall have the right to develop and Commercialize the Reverted Products itself or with one or more Third Parties, and shall have the right, without obligation to Histogenics, to take any such actions in connection with such activities as Intrexon (or its designee), at its discretion, deems appropriate.

(l) Confidential Information. Each Party shall promptly return, or at the other Party’s request destroy, any Confidential Information of the other Party in such Party’s possession or control at the time of termination; provided, however, that each Party shall be permitted to retain (i) a single copy of each item of Confidential Information of the other Party in its confidential legal files for the sole purpose of monitoring and enforcing its compliance with Article 7, (ii) Confidential Information of the other Party that is maintained as archive copies on the recipient Party’s disaster recovery and/or information technology backup systems in the ordinary course of business, or (iii) Confidential Information of the other Party necessary to exercise such Party’s rights in Retained Products (in the case of Histogenics) or Reverted Products (in the case of Intrexon). The recipient of Confidential Information shall continue to be bound by the terms and conditions of this Agreement with respect to any such Confidential Information retained in accordance with this Section 10.4(l).

(m) Cost Reimbursement. In the event of termination of this Agreement prior to achievement of the IND Acceptance Milestone Event either (i) by Intrexon pursuant to Section 10.2, or (ii) by Histogenics pursuant to Section 10.3, Histogenics shall pay to Intrexon fifty percent (50%) of Intrexon’s Fully Loaded Cost invoiced in connection with services under Section 4.6 (i.e., such that Intrexon will have in total been compensated for one hundred percent (100%) of the Fully Loaded Costs that were invoiced prior to the termination of this Agreement).

10.5 Surviving Obligations. Termination or expiration of this Agreement shall not affect any rights of either Party arising out of any event or occurrence prior to termination, including, without limitation, any obligation of Histogenics to pay any amount which became due and payable under the terms and conditions of this Agreement prior to expiration or such termination. The following portions of this Agreement shall survive termination or expiration of this Agreement: Sections 3.1 through 3.4 and 3.8(b) (each as applicable with respect to 10.4(b)), 5.2 through 5.9, 6.1, 6.2 (with subsection (c) surviving only to the extent relating to Intrexon Patents that are relevant to Retained Products that, to Intrexon’s knowledge, are being developed or Commercialized at such time, if any), 7.1, 7.2, 7.4, 7.5, 10.4, and 10.5; Articles 9, 11, and 12; and any relevant definitions in Article 1.

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,

47

CONFIDENTIAL TREATMENT REQUESTED

CONFIDENTIAL

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) 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 subsstantive 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, except as otherwise expressly provided in Section 11.2, 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, except as otherwise expressly provided in Section 11.2. The only damages recoverable under this Agreement are direct compensatory damages, except as otherwise expressly provided in Section 11.2.

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 an arbitration proceeding. Specifically, the Parties agree that a material breach by either Party of its obligations in Section 3.5 or Article 7 of 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 and equity, 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 the requirement of proving actual damages or posting a surety or 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.

49

CONFIDENTIAL

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 Party’s Patents shall be submitted to a court of competent jurisdiction in the country in which such Patent was filed or granted.

ARTICLE 12

GENERAL PROVISIONS

Exhibit A

Existing Product

NeoCart® is a cartilage-like implant created using patient’s own cartilage cells through a series of tissue engineering processes. First, the patient’s cells are separated from a tissue biopsy specimen extracted from the patient by a surgeon and multiplied in Histogenics’ laboratory. The cells are then infused into Histogenics’ proprietary scaffold that provides structure for the developing implant. Histogenics’ three-dimensional honeycomb collagen scaffolds are designed to produce a cartilage-like implant. The term “honeycomb” describes the shape of the pores inside of the scaffold as they are shaped like a honeycomb.

Before NeoCart is implanted in a patient, the cell- and scaffold construct undergoes a bioengineering process in our Tissue Engineering Processor (TEP). Histogenics’ proprietary TEPs incubate the cell- and scaffold-based implants under conditions designed to mimic the conditions found in the knee and joints, including pressure changes and low oxygen levels, so that the implant is prepared to begin functioning like normal healthy cartilage prior to implantation.

The NeoCart impant is shipped to physicans for implantation into the patient with Histogenics’ proprietary bioadhesive, CT3. CT3 is comprised of three components provided in syringes: methylated collagen, activated polyethylene glycol (PEG) and a simple salt buffering solution that acts as a curing component. The syringes of collagen and PEG are mixed at the time of surgery. When the NeoCart implant is implanted, the bioadhesive is used to anchor the NeoCart implant in the cartilage injury and seal the implant to the surrounding native cartilage interface. The curing agent is applied prior to closure of the surgical site.

The Existing Product therefore includes the cartilage-like implant comprised of cells and scaffold, the adhesive and the curing agent, along with certain tools to facilitate the spreading of adhesive and fixation of the implant and is being evaluated in Phase III clinical trials.

Nothing in this Section shall preclude or prohibit Intrexon from receiving and retaining any payment hereunder unless and until Intrexon has received a Default Notice (which shall be effective until waived in writing by the Silicon Valley Bank) or from converting this Note or any amounts due hereunder into shares of Common Stock. This Note shall be senior in all respects (including right of payment) to all other indebtedness of the Company, now existing or hereafter.

The Company has taken all corporate action required to make all the obligations of the Company reflected herein the valid and enforceable obligations they purport to be.

4.3. Compliance with Other Instruments.

4.4. Valid Issuance of Capital Stock.

5.2. Purchase Entirely for Own Account. Intrexon acknowledges that this Note is issued to Intrexon in reliance upon Intrexon’s representation to the Company that the Note will be acquired for investment for Intrexon’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that Intrexon has no present intention of selling, granting any participation in, or otherwise distributing the same.

Intrexon further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of this Note.

5.4. Investment Experience. Intrexon is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in this Note.

5.5. Accredited Investor. Intrexon is an “accredited investor” within the meaning of Rule 501 of Regulation D, as presently in effect, as promulgated by the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Act”).

5.6. Restricted Securities. Intrexon understands that this Note is characterized as a “restricted security” under the federal securities laws inasmuch as it is being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Act, only in certain limited circumstances. In this connection, Intrexon represents that it is familiar with Rule 144 as promulgated by the SEC under the Act, as presently in effect (“Rule 144”), and understands the resale limitations imposed thereby and by the Act.

5.7. Further Limitations on Disposition. Without in any way limiting the representations and warranties set forth above, Intrexon further agrees not to make any disposition of all or any portion of this Note unless and until the transferee has agreed in writing for the benefit of the Company to be bound by this Section 5, Section 8.8 and Section 8.9 and:

(a) There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b) (i) Intrexon shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the

CONFIDENTIAL TREATMENT REQUESTED

circumstances surrounding the proposed disposition, (ii) Intrexon shall not make any disposition to any of the Company’s competitors as such is in good faith determined by the Company’s Board of Directors, and (iii) if reasonably requested by the Company, Intrexon shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in extraordinary circumstances.

6. Further Agreements.

6.1. Conversion of the Note. The Note shall be convertible according to the following terms:

(a) The following terms shall have the meanings assigned below:

(i) “Corporate Transaction” means (A) the closing of the sale, transfer or other disposition of all or substantially all of the Company’s assets, (B) the consummation of the merger or consolidation of the Company with or into another entity (except a merger or consolidation in which the holders of capital stock of the Company immediately prior to such merger or consolidation continue to hold at least 50% of the voting power of the capital stock of the Company or the surviving or acquiring entity), (C) the closing of the transfer (whether by merger, consolidation or otherwise), in one transaction or a series of related transactions, to a person or group of affiliated persons (other than an underwriter of the Company’s securities), of the Company’s securities if, after such closing, such person or group of affiliated persons would hold 50% or more of the outstanding voting stock of the Company (or the surviving or acquiring entity), or (D) the liquidation, dissolution or winding up of the Company; provided, however, that a transaction shall not constitute a Corporate Transaction if its sole purpose is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately prior to such transaction. Notwithstanding the prior sentence, the sale of shares of the Company’s preferred stock, par value $0.001 (the “Preferred Stock”) in a bona fide financing transaction that would not otherwise qualify as a “Corporate Transaction” under the foregoing definition shall not be deemed a “Corporate Transaction.”

(ii) “Equity Securities” means the Company’s Common Stock or Preferred Stock or any securities conferring the right to purchase the Company’s Common Stock or Preferred Stock or securities convertible into, or exchangeable for (with or without additional consideration), the Company’s Common Stock or Preferred Stock, except any security granted, issued and/or sold by the Company to any director, officer, employee or consultant of the Company in such capacity for the primary purpose of soliciting or retaining their services.

Exhibit C

A. INFORMATION RIGHTS

1. Information Rights.

If, at any time, Intrexon determines that it is required by any law, regulation or any regulatory body applicable to Intrexon, to include information concerning the Company (including, but not limited to, financial information) in any reports or filings, then the Company shall use commercially reasonable best efforts to provide all such reports and information concerning the business and affairs of the Company as Intrexon may reasonably request, in each case within a reasonable time following such request.

B. REGISTRATION RIGHTS

1. Piggyback Registration Rights.

If, at any time, the Company proposes to file a registration statement under the Securities Act, other than a registration relating solely to employee benefit plans or Rule 145 transactions, with respect to an underwritten offering for its own account of any class of securities of the Company (a “Registration Statement”), then each such time, the Company shall give written notice of such intention to file a Registration Statement (a “Piggyback Notice”) to Intrexon at least five (5) days before the anticipated filing date. The Piggyback Notice shall describe the number of shares to be registered and the intended method of distribution and offer Intrexon the opportunity to register pursuant to such Registration Statement such shares held by Intrexon (the “Registrable Shares”) as Intrexon may request in writing to the Company within five (5) days after the date Intrexon first received the Piggyback Notice (a “Piggyback Registration”). The Piggyback Registration rights shall be subject ratably to potential underwriter’s limitations set forth herein. The Company shall take all reasonable steps to include in the Registration Statement the Registrable Shares which the Company has been so requested to register by Intrexon. The Company shall be entitled to suspend or withdraw a Registration Statement prior to its becoming effective. If the managing underwriter with respect to such an offering advises the Company in writing that the inclusion of all or any portion of the Registrable Shares which Intrexon has requested to be included in the Registration Statement would materially jeopardize the success of the offering, then the Company shall be required to include in the underwriting only that number of Registrable Shares which the underwriter advises the Company in writing may be sold without materially jeopardizing the offering. If Intrexon disapproves of the terms of any such underwriting may elect to withdraw its Registrable Shares from it by written notice to the Company and the underwriter. Intrexon also agrees to be subject to any lock-up agreements reasonably requested by a managing underwriter so long as the Company shares held by the Company’s largest shareholder are also subject to a similar lock-up agreement.

2. Registration Expenses.

All reasonable fees and expenses incident to the performance of or compliance with the Registration Rights contained in this Agreement by the Company, except as and to the extent specified in this section, shall be borne by the Company whether or not the Registration Statement is filed or becomes effective and whether or not any shares are sold pursuant to the Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with each securities exchange or market on which shares are listed, (B) with respect to filings required to be made with the Financial Industry Regulatory Authority and (C) in compliance with state securities or Blue Sky laws, (ii) messenger, telephone and delivery expenses, (iii) fees and disbursements of counsel for the Company, (iv) Securities Act liability insurance, if the Company so desires such insurance, and (v) fees and expenses of all other

CONFIDENTIAL TREATMENT REQUESTED

persons or entities retained by the Company in connection with the consummation of the transactions contemplated by this section, including, without limitation, the Company’s independent public accountants. Notwithstanding the foregoing, any costs that are incurred by Intrexon or that relate specifically and solely to the inclusion of Intrexon’s securities in a registration that are in excess of $20,000 per Registration Statement shall be borne by Intrexon.

3. Indemnification by the Company.

The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless Intrexon, its permitted assignees, officers, directors, agents, Affiliates and employees, to the fullest extent permitted by applicable law, from and against any and all claims, losses, damages, liabilities, penalties, judgments, costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) (collectively, “Losses”), arising out of or relating to any untrue or alleged untrue statement of a material fact contained in a Registration Statement or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except (i) to the extent that such untrue statements or omissions are based upon information furnished to the Company by Intrexon expressly for use in the Registration Statement; (ii) as a result of the failure of such indemnitee to deliver a prospectus, as amended or supplemented, to a purchaser in connection with an offer or sale; or (iii) the use by the indemnitee of an outdated or defective prospectus after the Company has notified Intrexon in writing that the prospectus is outdated or defective, but only if and to the extent that following such receipt the misstatement or omission giving rise to such Loss would have been corrected; provided, however, that the indemnity agreement contained in this section shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.

4. Indemnification by Intrexon.

Intrexon shall indemnify and hold harmless the Company, its directors, officers, agents and employees to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in a Registration Statement or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, to the extent that such untrue statement or omission is contained in or omitted from any information regarding Intrexon furnished in writing to the Company by Intrexon expressly for use in therein, and that such information was reasonably relied upon by the Company for use therein, or to the extent that such information relates to Intrexon or Intrexon’s proposed method of distribution of shares and was furnished in writing by Intrexon expressly for use therein. Notwithstanding anything to the contrary contained herein, in no event shall the liability of Intrexon under this section exceed the net proceeds to Intrexon as a result of the sale of shares pursuant to a Registration Statement in connection with which the untrue or alleged untrue statement or material omission was provided.

C. PRE-EMPTIVE RIGHTS

1.1 Intrexon Election. Until the 5^th anniversary of the Effective Date of the ECC, Intrexon shall be entitled to, at its election, participate in each Qualified Financing (as hereinafter defined) conducted by the Company and may purchase as part of, or in connection with, such Qualified Financing an amount of Common Stock or other the Company securities issued and sold by the Company in the Qualified Financing (excluding the securities sold pursuant to this Section 1.1) equal to a pro-rata portion of the aggregate securities offered in the Qualified Financing based on Intrexon’s percentage ownership of the issued and outstanding securities of the Company (on a fully-diluted basis) as of the time of such Qualified Offering (collectively, the “Equity Purchase Participation Right”). For the purposes of Article C of this Exhibit C, a “Qualified Financing” shall mean a sale by the Company of Common Stock, or equity securities convertible into Common Stock, in a public or private offering for primarily equity financing purposes. The price per share paid by Intrexon in any such Qualified Financing shall be the same as that paid by the other investors in such Qualified Financing, and Intrexon shall receive securities of the same type and with the same rights, preferences and privileges as the other investors in such Qualified Financing, including, for example, any warrant coverage, subject to the execution by Intrexon of the investment documents entered into by the other investors in the Qualified Financing.

1.2 In the event that the Qualified Financing is a public offering made pursuant to a registration statement filed with the SEC pursuant to the Securities Act:

(a) Upon receipt of the prospectus and other offering documents prepared by the Company in connection with such public offering, Intrexon shall, within ten (10) days of receipt of such documents, notify the Company as to whether Intrexon wishes to participate in the Qualified Financing.
