SCOPE OF CHANNEL COLLABORATION; MANAGEMENT 

2.1 Scope. 
 (a) Generally. The general purpose of the channel collaboration described in this Agreement will be to use the Intrexon Channel Technology to research, develop and Commercialize Ampliphi Products
for use in the Field (collectively, the “Bacteriophage Program”). As provided below, the JSC shall establish, monitor, and govern projects for the Bacteriophage Program. Either Party may propose potential projects in the Field for
review and consideration by the JSC. 
 (b) Reservation of Bactgeriophage Veterninary Applications. Intrexon and Ampliphi
desire to provide a limited time period for the Parties after the Effecive Date to consider entering into a second exclusive channel collaboration agreement pertaining to certain veterinary applications in the Reserved Field. For a time period of
one year immediately following the Effective Date, neither Intrexon nor its Affiliates shall make the Intrexon Channel Technology or Intrexon Materials available to any Third Party for the purpose of developing or Commercializing products in the
Reserved Field, and neither Intrexon nor any Affiliate shall pursue (either by itself or with a Third Party or Affiliate) the Commercialization of any product for purpose of commercial use or sale in the Reserved Field. For clarity, nothing in the
preceding sentence, however, shall prevent Intrexon from performing general research and development that may be applicable to the Reserved Field. During the one-year period following the Effective Date, Intrexon will not propose, negotiate, or
enter into any collaboration or Commercialization agreement with a Third Party within the Reserved Field, and will, at Ampliphi’s request, enter into negotiations directed toward the execution of a second exlcusive channel collaboration between
the parties, which second exclusive channel collaboration will be directed to the Reserved Field (or a subset of the Reserved Field as mutually agreed by the Parties). The terms of this second exclusive channel collaboration agreement will be
subject to good faith negotiation of the parties with respect to any terms relating to consideration (up-front, milestones, and royalty payments) that will be due to Intrexon, the scope of exclusive field within the Reserved Field, and the relative
rights of the Parties to continue products following any termination, but otherwise will contain similar terms, rights and obligations of the parties as set forth herein.

 (a) Generally. The Parties desire to establish several committees (collectively,
“Committees”) to oversee the Bacteriophage Program and to facilitate communications between the Parties with respect thereto. Each of such Committees shall have the responsibilities and authority allocated to it in this Article 2.
Each of the Committees shall have the obligation to exercise its authority consistent with the respective purpose for such Committee as stated herein and any such decisions shall be made in good faith. 

(b) Formation and Purpose. Promptly following the Effective Date, the Parties shall confer and then create the JSC and the IPC,
and, optionally, create one or more of the other Committees listed in the chart below. Each Committee shall have the purpose indicated in the chart. To the extent that after conferring both Parties agree to not create a Committee (other than the JSC
and the IPC), the creation of such Committee shall be deferred until one Party informs the other Party of its then desire to create the so-deferred Committee, at which point the Parties will thereafter promptly create the so-deferred Committee.

 2.3 General Committee Membership and Procedure. 

(a) Membership. For each Committee, each Party shall designate an equal number of representatives (not to exceed three
(3) for each Party) with appropriate expertise to serve as members of such Committee. For the JSC, the representatives must all be employees of such Party or an Affiliate of such Party. For Committees other than the JSC, the representatives
must all be employees of such Party or an Affiliate of such Party, with the caveat that each Party may designate for each such other Committee up to one (1) representative who is not an employee if : (i) such non-employee representative
agrees in writing to be bound to the terms of this Agreement for the treatment and ownership of Confidential Information and Inventions of the Parties, and (ii) the other Party consents to the designation of such non-employee representative,
which consent shall not be unreasonably withheld. For purposes of this Section 2.3, employees of Third Security may, at Intrexon’s election, serve as members of a Committee as if they were employees of Intrexon. Each representative as
qualified above may serve on more than one (1) Committee as appropriate in view of the individual’s expertise. Each Party may replace its Committee representatives at any time upon written notice to the other Party, provided that any
replacement shall be qualified as set forth above. Each Committee shall have a chairperson; the chairperson of each committee shall serve for a two-year term and the right to designate which representative to the Committee will act as chairperson
shall alternate between the Parties, with Ampliphi selecting the chairperson first for the JSC, RC and CC, and Intrexon selecting the chairperson first for the CMCC and IPC. The chairperson of each Committee shall be responsible for calling
meetings, preparing and circulating an agenda in advance of each meeting of such Committee, and preparing and issuing minutes of each meeting within fifteen (15) days thereafter. 

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

Party will disclose to the other proposed agenda items along with appropriate information at least three (3) business days in advance of each meeting of the applicable Committee; provided, that a Party may provide its agenda items to the other
Party within a lesser period of time in advance of the meeting, or may propose that there not be a specific agenda for a particular meeting, so long as such other Party consents to such later addition of such agenda items or the absence of a
specific agenda for such Committee meeting. 
 (d) Limitations of Committee Powers. Each Committee shall have only such
powers as are specifically delegated to it hereunder or from time to time as agreed to in writing by the mutual consent of the Parties and shall not be a substitute for the rights of the Parties. Without limiting the generality of the foregoing, no
Committee shall have any power to amend this Agreement. Any amendment to the terms and conditions of this Agreement shall be implemented pursuant to Section 12.7 below.

may provide written notice of such dispute to the Executive Officer of the other Party. The Executive Officers of each of the Parties will meet at least once in person or by means of telecommunication (telephone, video, or web conferences) to
discuss the dispute and use their good faith efforts to resolve the dispute within thirty (30) days after submission of such dispute to the Executive Officers. If any such dispute is not resolved by the Executive Officers within thirty
(30) days after submission of such dispute to such Executive Officers, then the Executive Officer of the Party specified in the applicable subsection below shall have the authority to finally resolve such dispute acting in good faith.

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

 3.2 Sublicensing. Except as provided in this Section 3.2, Ampliphi shall not
sublicense the rights granted under Section 3.1 to any Third Party, or transfer the Intrexon Materials to any Third Party, or otherwise grant any Third Party the right to research, develop, use, or Commercialize Ampliphi Products or use or
display the Intrexon Trademarks, in each case except with Intrexon’s written consent, which written consent may be withheld in Intrexon’s sole discretion. Notwithstanding the foregoing, Ampliphi shall have a limited right to sublicense
under the circumstances described in Sections 3.2(a), 3.2(b) and 3.2(c). 
 (a) Ampliphi may transfer, to the extent
reasonably necessary and after providing Intrexon with reasonable advance notice thereof, Intrexon Materials that are or express Ampliphi Products to a Third Party contractor performing contract manufacturing, fill, and/or finish responsibilities
for Ampliphi Products, and may in connection therewith grant limited sublicenses necessary to enable such Third Party to perform such activities. If Ampliphi transfers any Intrexon Materials under this Section 3.2(a), Ampliphi will remain
obligated 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 such Third Party contractor. 

(b) Ampliphi may, with Intrexon’s written consent, which consent shall not be unreasonably withheld or delayed, sublicense
the rights granted under Section 3.1 to an Affiliate, or transfer the Intrexon Materials to an Affiliate, or grant an Affiliate the right to display the Intrexon Trademarks. In the event that Intrexon consents to any such grant or transfer to
an Affiliate, Ampliphi 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 Ampliphi), including any payment obligations owed to Intrexon hereunder. 
 (c) Ampliphi may, upon
approval of the JSC and with Intrexon’s written consent, which consent shall not be unreasonably withheld or delayed, sublicense the rights granted under Section 3.1 to a Third-Party, or transfer the Intrexon Materials to a Third Party, in
each case who is providing services to Ampliphi in connection with Ampliphi’s exercise of rights under this Agreement, provided that such sublicense or use of Intrexon Materials shall be limited to those rights or uses necessary for such Third
Party to provide such services. In the event that Intrexon consents to any such grant or transfer to such a Third Party, Ampliphi shall remain responsible for the performance by any such Third Party and shall cause such Third Party to comply with
the provisions of this Agreement in connection with such performance (as though such Third Party were Ampliphi). 
 3.3
Limitation on Sublicensees. None of the enforcement rights under the Intrexon Patents that are granted to Ampliphi 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. Ampliphi 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 or Intrexon Materials available to any Third Party for the purpose of developing or Commercializing products in the Field (except as set forth in Section 3.2), 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 Bacteriophage Program. Further, neither Ampliphi nor its Affiliates shall
pursue (either by itself or with a Third Party or Affiliate) outside of the Bacteriophage Program the research, development or Commercialization of any product for purpose of commercial use or sale in the Field. For clarity, the foregoing sentence
shall not restrict Ampliphi’s rights to research, develop or Commercialize any bacteriophage therapeutic product in which the only bacteriophages included in such therapeutic are developed, selected, or produced without the use of synthetic DNA
technology, including bacteriophages selected through screening libraries, evolutionary selection or other techniques that do not involve the direct manipulation of nucleic acid sequences. 

3.6 No Prohibition on Intrexon. Except as explicitly set forth in Sections 2.1(b), 3.1 and 3.5, nothing in this Agreement shall
prevent Intrexon from practicing or using the Intrexon Materials, Intrexon Channel Technology, and Intrexon IP for any purpose, and to grant to Third Parties the right to do the same. Without limiting the generality of the foregoing, Ampliphi
acknowledges that, except as set forth in Section 2.1(b) with respect to the Reserved Field, Intrexon has all rights, in Intrexon’s sole discretion, to use or make the Intrexon Materials, Intrexon Channel Technology (including any genetic
materials used in an Ampliphi Product), and Intrexon IP available to Third Party channel partners or collaborators for use in fields outside the Field. 
 3.7 Rights to Regulatory Data. Ampliphi shall own and control all regulatory trial data and regulatory filings relating to Commercialization of Ampliphi Products (except to the extent such become
Reverted Products). Ampliphi shall provide to Intrexon at Intrexon’s request full copies of all trial data and reports, regulatory filings, and communications from regulatory authorities that relate specifically and solely to Ampliphi Products.
To the extent that there exist any trial data and reports, regulatory filings, and communications from regulatory authorities owned by Ampliphi that relate both to Ampliphi Products and other products produced by Ampliphi outside the Field or
outside the Bacteriophage Program, upon Intrexon’s request Ampliphi shall provide to Intrexon copies of the portions of such data, reports, filings, and communications that relate to Ampliphi Products, provided any such materials shall be
Confidential Information of Ampliphi (except to the extent such become Reverted Products). Subject to its ongoing obligations of exclusivity under Section 3.5, Intrexon shall be permitted, directly or in conjunction with or through partners or
other channel collaborators, to reference this data, reports, filings, and communications relating to Ampliphi Products in regulatory filings made to obtain regulatory approval for products for use in fields outside the Field. Intrexon shall have
the right to use any such information in developing and Commercializing products outside the Field and to license any Third Parties to do so. Notwithstanding the provisions of this Section 3.7, Intrexon shall not, outside of the Bacteriophage
Program, utilize any Ampliphi trial data or reports in support of obtaining regulatory approval for a product for use in the Field.

 3.8 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 Intrexon to conduct genetic and cell engineering and related analytic activities under JSC established plans for the Bacteriophage Program (but specifically
excluding intellectual property directed to any specific target genes, methods of treatment or therapy, cell lines, active pharmaceutical ingredients, delivery or packaging methods or apparatuses, or processes or methods for commercially
manufacturing Ampliphi Products) (“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 Ampliphi 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 Ampliphi 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 (to the extent 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 [*****]. For the avoidance of doubt, [*****] may at any time obtain a license under Complementary In-Licensed Third Party IP outside the Field [*****] 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, [*****] 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 In-Licensed Program IP outside the Field, it will do so on a non-exclusive basis unless it obtains the prior written
consent of [*****] for such license outside the Field to be exclusive. Notwithstanding the foregoing sentence, [*****] shall have the right to acquire exclusive rights to Supplemental In-Licensed Third Party IP outside the Field if (i) such
rights outside the Field are limited specifically to non-genetically modified bacteriophages and, (ii) [*****] provides [*****] with thirty days notice prior to execution of any such exclusive rights to Supplemental In-Licensed Third Party IP.
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 Ampliphi or its Affiliates obtain a license under Patents claiming inventions or know-how specific to or used or incorporated into the development,
manufacture, and/or Commercialization of Ampliphi Products, Ampliphi shall use commercially reasonable efforts to ensure that Ampliphi will have the ability, pursuant to Section 10.4(h), to assign such agreement to Intrexon or grant a
sublicense to Intrexon thereunder (having the scope set forth in Section 10.4(h)). 
 (e) The licenses granted to
Ampliphi 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 3.8(c), provided that Intrexon shall either provide unredacted copies of such upstream license agreements to Ampliphi or shall disclose in writing to Ampliphi all of such
terms and conditions that are applicable to Ampliphi. Ampliphi 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 Ampliphi as provided
in the preceding sentence. 
 (f) If either Party receives 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. 
 3.9 Licenses to Intrexon. Subject to
the terms and conditions of this Agreement, Ampliphi hereby grants to Intrexon a non-exclusive, worldwide, fully-paid, royalty-free license, under any applicable Patents or other intellectual property Controlled by Ampliphi or its Affiliates, 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 4.6 or as otherwise permitted to be used by Intrexon in conjunction with support services under Section 4.7 (subject to JSC research plan approval).

 3.10 Restrictions Relating to Intrexon Materials. Ampliphi and its permitted
sublicensees shall use the Intrexon Materials solely for purposes of the Bacteriophage 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, Ampliphi shall not, and shall ensure that Ampliphi 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 4.6 and 4.7, Ampliphi shall be solely responsible for the development
and Commercialization of Ampliphi Products. Ampliphi shall be responsible for all costs incurred in connection with the Bacteriophage Program except that Intrexon shall be responsible for the following: (a) costs of establishing manufacturing
capabilities and facilities in connection with Intrexon’s manufacturing obligation under Section 4.6 (provided, however, that Intrexon may include an allocable portion of such costs, through depreciation and amortization, when calculating
the Fully Loaded Cost of manufacturing an Ampliphi 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 4.7 or research requested
by the JSC for the development of an Ampliphi Product (which research costs shall be reimbursed by Ampliphi); (c) [*****]; and (d) costs of filing, prosecution and maintenance of Intrexon Patents. The costs encompassed within clause
(a) of the previous sentence shall include the scale-up of Intrexon Materials for generating data for regulatory approval submissions and Commercialization of Ampliphi Products undertaken pursuant to Section 4.6, which shall be at
Intrexon’s cost whether it elects to conduct such efforts internally or through Third Party contractors retained by either Intrexon or Ampliphi (with Intrexon’s consent). 

4.2 Transfer of Technology and Information. The JSC shall develop a plan and protocol for each project and timing for the transfer
of relevant data and materials between the Parties. 
 4.3 Information and Reporting. Ampliphi will keep Intrexon
informed about Ampliphi’s efforts to develop and Commercialize Ampliphi Products, including reasonable and accurate summaries of Ampliphi’s (and its Affiliates’ and, if applicable, (sub)licensees’) development plans (as updated),
including regulatory plans, marketing plans (as updated),

progress towards meeting the goals and milestones in such plans and explanations of any material deviations, significant developments in the development and/or Commercialization of the Ampliphi
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 3.7 above, Ampliphi shall also provide to Intrexon copies of all final regulatory trial protocols and reports, and regulatory
correspondence and filings generated by Ampliphi as soon as practical after they become available. Intrexon will keep Ampliphi informed about Intrexon’s efforts (a) to establish manufacturing capabilities and facilities for Ampliphi
Products (and Intrexon Materials relevant thereto) and otherwise perform its manufacturing responsibilities under Section 4.6 and (b) to undertake discovery-stage research for the Bacteriophage Program with respect to the Intrexon Channel
Technology and Intrexon Materials. Unless otherwise provided herein or directed by the JSC in accord with Section 4.2 above, such disclosures by Ampliphi and Intrexon will be coordinated by the JSC and made in connection with JSC meetings at
least once every six (6) months while Ampliphi Products are being developed or Commercialized anywhere in the world, and shall be reflected in the minutes of such meetings. 

4.4 Regulatory Matters. At all times after the Effective Date, Ampliphi shall own and maintain, at its own cost, all regulatory
filings and regulatory approvals for Ampliphi Products that Ampliphi is developing or Commercializing pursuant to this Agreement. As such, Ampliphi shall be responsible for reporting all adverse events related to such Ampliphi 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 Ampliphi 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 Ampliphi,
Intrexon, and relevant third parties with respect to specific Intrexon Materials. 
 4.5 Diligence. 

(a) Ampliphi shall use, and shall require its sublicensees to use, Diligent Efforts to develop and Commercialize Ampliphi
Products. 
 (b) Without limiting the generality of the foregoing, Intrexon may, from time to time, notify Ampliphi that
it believes it has identified a Superior Therapy, and in such case Intrexon shall provide to Ampliphi its then-available information about such therapy and reasonable written support for its conclusion that the therapy constitutes a Superior
Therapy. Ampliphi shall have the following obligations with respect to such proposed Superior Therapy: (i) within sixty (60) days after such notification, Ampliphi shall prepare and deliver to the JSC for review and approval a development
plan detailing how Ampliphi will pursue the Superior Therapy (including a proposed budget), provided that if Amplphi reasonably requests supplemental information in support of the determination that the proposed Ampliphi Product is a Superior
Therapy, such period shall be extended to sixty (60) days after Ampliphi receives

such supplemental inforation; (ii) Ampliphi shall revise the development plan as directed by the JSC; and (iii) following approval of the development plan by the JSC, Ampliphi shall use
Diligent Efforts to pursue the development of the Superior Therapy under the Bacteriophage Program in accordance with such development plan. If Ampliphi fails to comply with the foregoing obligations, or if Ampliphi 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 4.5, 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. 
 (c) The activities of Ampliphi’s Affiliates and any permitted sublicensees shall be attributed
to Ampliphi for the purposes of evaluating Ampliphi’s fulfillment of the obligations set forth in this Section 4.5. 

4.6 Manufacturing. Intrexon shall have the option and, in the event it so elects, shall use Diligent Efforts, to perform any
manufacturing activities in connection with the Bacteriophage Program that relate to the Intrexon Materials, including through the use of a suitable Third Party contract manufacturer. To the extent that Intrexon so elects, Intrexon may request that
Ampliphi and Intrexon 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 Intrexon Materials.
Except as provided in Section 4.1, any manufacturing undertaken by Intrexon pursuant to the preceding sentence shall be performed in exchange for cash payments equal to Intrexon’s Fully Loaded Cost in connection with such manufacturing, on
terms to be negotiated by the Parties in good faith. In the event that Intrexon does not manufacture Intrexon Materials or bulk quantities of other components of Ampliphi Products, then Intrexon shall provide to Ampliphi or a contract manufacturer
selected by Ampliphi and approved by Intrexon all Information Controlled by Intrexon that is (a) related to the manufacturing of such Intrexon Materials or bulk qualities of other components of Ampliphi Products for use in the Field and
(b) reasonably necessary to enable Ampliphi or such contract manufacturer (as appropriate) for the sole purpose of manufacturing such Intrexon Materials or bulk quantities of other components of Ampliphi Products. The costs and expenses
incurred by Intrexon in carrying out such transfer shall be borne by Intrexon. Any manufacturing Information transferred hereunder to Ampliphi or its contract manufacturer shall not be further transferred to any Third Party, including any
sublicensee of Ampliphi, or any Ampliphi Affiliate without the prior written consent of Intrexon; provided, however, that Intrexon shall not unreasonably withhold such consent if necessary to permit Ampliphi to switch manufacturers. 

4.7 Support Services. The JSC will meet promptly following the Effective Date and establish a plan under which Intrexon will
provide support services to Ampliphi for the research and development of Ampliphi Products under the Bacteriophage Program, which initial

plan may be amended from time to time by the JSC. Ampliphi will compensate Intrexon for such support services with cash payments equal to Intrexon’s Fully Loaded Cost in connection with such
services. Additionally, from time to time, on an ongoing basis, Ampliphi shall request, or Intrexon may propose, that Intrexon perform certain additional support services with respect to researching and developing new Ampliphi Products or improving
the manufacturing or processing methods for any existing Ampliphi Products. To the extent that the Parties mutually agree that Intrexon should perform such additional services, the Parties shall negotiate in good faith the terms under which services
would be performed, it being understood that Intrexon would be compensated for such services by cash payments equal to Intrexon’s Fully Loaded Cost in connection with such services. 

4.8 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 Bacteriophage Program, including without limitation those relating to the transport, storage, and handling of Intrexon Materials and Ampliphi Products. 

4.9 Trademarks and Patent Marking. To the extent permitted by applicable law and regulations, Ampliphi shall ensure that the
packaging, promotional materials, and labeling for Ampliphi Products, as appropriate, shall carry the applicable Intrexon Trademark(s), subject to Ampliphi’s reasonable approval of the size, position, and location thereof. Consistent with the
U.S. patent laws, Ampliphi shall ensure that Ampliphi Products, or their respective packaging or accompanying literature as appropriate, bear applicable and appropriate patent markings for Intrexon Patent numbers. Ampliphi shall provide Intrexon
with copies of any materials containing the Intrexon Trademarks or patent markings prior to using or disseminating such materials, in order to obtain Intrexon’s approval thereof. Ampliphi’s use of the Intrexon Trademarks and patent
markings shall be subject to prior review and approval of the IPC. Ampliphi acknowledges Intrexon’s sole ownership of the Intrexon Trademarks and agrees not to take any action inconsistent with such ownership. Ampliphi covenants that it shall
not use any trademark confusingly similar to any Intrexon Trademarks in connection with any products (including any Ampliphi Product). From time to time during the Term, Intrexon shall have the right to obtain from Ampliphi samples of Ampliphi
Product sold by Ampliphi or its Affiliates or sublicensees, or other items which reflect public uses of the Intrexon Trademarks or patent markings, for the purpose of inspecting the quality of such Ampliphi Products, the use of the Intrexon
Trademarks, or the accuracy of the patent markings. In the event that Intrexon inspects under this Section 4.9, Intrexon shall notify the result of such inspection to Ampliphi in writing thereafter. Ampliphi shall comply with reasonable
policies provided by Intrexon from time-to-time to maintain the goodwill and value of the Intrexon Trademarks.

 For three (3) years after each sale or other commercial use of Ampliphi Product, or after incurring
any component item Ampliphi incorporated into its calculation of Net Sales or Sublicensing Revenues, or otherwise impacting Ampliphi’s calculations with regard to payments made to Intrexon in accord with Section 5.4(a) or 5.4(b), Ampliphi
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, Ampliphi shall permit an independent certified public accounting firm of internationally recognized standing selected by Intrexon, and reasonably
acceptable to Ampliphi, 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 Ampliphi and its Affiliates to verify the accuracy and timeliness of
the reports and payments made by Ampliphi 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,
Ampliphi 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 Ampliphi 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 5.7 in accordance with the confidentiality provisions of Article 7 and (ii) cause its accounting firm
to enter into an acceptable confidentiality agreement with Ampliphi 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. Ampliphi 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 Ampliphi or the appropriate governmental authority
(with the assistance of Ampliphi 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 Ampliphi of its obligation to withhold tax, and Ampliphi shall apply the reduced rate of withholding tax, or dispense with withholding tax, as the
case may be, provided that Ampliphi 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, Ampliphi 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 amount owed by Ampliphi 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. 

ARTICLE 6 

INTELLECTUAL PROPERTY 
 6.1 Ownership. 
 (a) Subject to the license granted under
Section 3.1, all rights in the Intrexon IP shall remain with Intrexon. 
 (b) Ampliphi and/or Intrexon may solely or
jointly conceive, reduce to practice or develop discoveries, inventions, processes, techniques, and other technology, whether or not patentable, in the course of performing the Bacteriophage Program (collectively “Inventions”). Each
Party shall promptly provide the other Party with a detailed written description of any such Inventions that relate to the Field. Inventorship shall be determined in accordance with United States patent laws. 

(c) Intrexon shall solely own all right, title and interest in all Inventions made with, using, or otherwise incorporating
Intrexon Channel Technology, together with all Patent rights and other intellectual property rights therein (the “Channel-Related Program IP”). Ampliphi hereby assigns all of its right, title and interest in and to the
Channel-Related Program IP to Intrexon. Ampliphi agrees to execute such documents and perform such other acts as Intrexon may reasonably request to obtain, perfect and enforce its rights to the Channel-Related Program IP and the assignment thereof.

 (d) Notwithstanding anything to the contrary in this Agreement, any discovery, invention, process, technique, or other
technology, whether or not patentable, that is conceived, reduced to practice or developed by Ampliphi 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.

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

6.2 Patent Prosecution. 
 (a) Intrexon shall have the sole right, but not the obligation, to (i) conduct and control the filing, prosecution and maintenance of the Intrexon Patents, and (ii) 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 Ampliphi Product. At the reasonable request of
Intrexon, Ampliphi shall cooperate with Intrexon in connection with such filing, prosecution, and maintenance, at Intrexon’s expense. Under no circumstances shall Ampliphi (A) 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 uses or purports to claim or use or relies for support upon an Invention owned by Intrexon, or (B) 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, or (C) without prior approval of the IPC, file, attempt to file, or assist anyone else in filing, or attempting to file, any application for patent term extension or
supplementary protection certificate, either in the United States or elsewhere, that relies upon the regulatory approval of an Ampliphi Product. 
 (b) Ampliphi shall have the sole right, but not the obligation, to conduct and control the filing, prosecution and maintenance of any Patents claiming Inventions that are owned by Ampliphi or its
Affiliates and not assigned to Intrexon under Section 6.1(c) (“Ampliphi Program Patents”). At the reasonable request of Ampliphi, Intrexon shall cooperate with Ampliphi in connection with such filing, prosecution, and
maintenance, at Ampliphi’s expense. 
 (c) As used in this Section, “Prosecuting Party” means
Intrexon in the case of Intrexon Patents and Ampliphi in the case of Ampliphi Program Patents. The Prosecuting Party shall be entitled to use patent counsel selected by it and reasonably acceptable to the non-Prosecuting Party (including in-house
patent counsel as well as outside patent counsel) for the prosecution of the Intrexon Patents and Ampliphi Program Patents, as applicable. The Prosecuting Party shall: 
 (i) regularly provide the other Party in advance with reasonable information relating to the Prosecuting Party’s prosecution of Patents hereunder, including by providing copies of substantive
communications, notices and actions submitted to or received from the relevant patent authorities and copies of drafts of filings and correspondence that the

Prosecuting Party proposes to submit to such patent authorities (it being understood that, to the extent that any such information is readily accessible to the public, the Prosecuting Party may,
in lieu of directly providing copies of such information to such other Party, provide such other Party with sufficient information that will permit such other Party to access such information itself directly); 

(ii) consider in good faith and consult with the non-Prosecuting Party regarding its timely comments with respect to the same; provided,
however, that if, within fifteen (15) days after providing any documents to the non-Prosecuting Party for comment, the Prosecuting Party does not receive any written communication from the non-Prosecuting Party indicating that it has or may
have comments on such document, the Prosecuting Party shall be entitled to assume that the non-Prosecuting Party has no comments thereon; 
 (iii) consult with the non-Prosecuting Party before taking any action that would reasonably be expected to have a material adverse impact on the scope of claims within the Intrexon Patents and Ampliphi
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. 
 (b) Notwithstanding the foregoing, Ampliphi 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 Ampliphi exercises the foregoing right, Intrexon agrees to be named in any such action if required. If Ampliphi 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 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 Ampliphi shall be entitled to a share of the Recovery a set forth in Section 6.3(f), Intrexon and Ampliphi 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 Ampliphi on such determination. For the avoidance of doubt, Intrexon has
no obligations 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) Ampliphi 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. Intrexon shall not settle or otherwise compromise any action under
this Section 6.3 in a way that diminishes the rights or interests of Ampliphi in the Field or adversely affects any Intrexon Patent with respect to the Field without Ampliphi’s prior written consent, which consent shall not be unreasonably
withheld. 
 (f) Except as otherwise agreed to by the Parties in writing, any settlements, damages or other monetary
awards recovered pursuant to a suit, proceeding, or action brought pursuant to Section 6.3 will be allocated first to the costs and expenses of the Party controlling such action, and second, to the costs and expenses (if any) of the other Party
(to the extent not otherwise reimbursed), and any remaining amounts (the “Recovery”) will be shared by the Parties as follows: In any action initiated by Intrexon pursuant to Section 6.3(a) that does not involve Field
Infringement, or in any action initiated by Intrexon pursuant to Section 6.3(b), Intrexon shall retain one hundred percent (100%) of any Recovery. In any action initiated by Ampliphi pursuant to Section 6.3(b), Ampliphi shall retain
one hundred percent (100%) of any Recovery, but such Recovery shall be shared with Intrexon as Net Sales. In any action initiated by Intrexon or Ampliphi pursuant to Section 6.3(c), the Parties shall share the Recovery equally, and such
Recovery shall not be deemed to constitute Sublicensing Revenue. 
 (g) Ampliphi shall promptly notify Intrexon in
writing of any suspected, alleged, threatened, or actual Infringement of which it becomes aware, and Intrexon shall promptly notify Ampliphi in writing of any suspected, alleged, threatened, or actual Field Infringement of which it becomes aware.

 (e) was independently discovered or developed by the receiving Party without the use of
Confidential Information belonging to the disclosing Party, as documented by the receiving Party’s written records. 
 The
foregoing non-use and non-disclosure obligation shall continue (i) indefinitely, for all Confidential Information that qualifies as a trade secret under applicable law; or (ii) for the Term of this Agreement and for seven (7) years

Party may disclose the Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary in the following instances: 
 (a) complying with applicable laws or regulations or valid court orders, provided that the Party making such disclosure provides the other Party with reasonable prior written notice of such
request or demand for disclosure and makes a reasonable effort to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the disclosure and/or requiring that the terms and conditions of this Agreement be used
only for the purposes for which the law or regulation required, or for which the order was issued; 
 (b) to regulatory
authorities in order to seek or obtain approval to conduct regulatory trials, or to gain regulatory approval, of Ampliphi Products or any products being developed by Intrexon or its other licensees and/or channel partners or collaborators, provided

agree to be bound by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 7; and 
 (e) disclosure of the terms of this Agreement by Intrexon to collaborators and other channel partners or collaborators who agree to be bound by obligations of confidentiality and non-use at least
equivalent in scope to those set forth in this Article 7. 
 7.3 Publicity; Publications. The Parties agree that the
public announcement of the execution of this Agreement shall be substantially in the form of a press release and/or the filing of a Form 8-K by Ampliphi, which shall be mutually agreed to by the Parties. Each Party will provide the other Party with
the opportunity to review and comment, prior to submission or presentation, on external reports, publications and presentations (e.g., press releases, reports to government agencies, abstracts, posters, manuscripts and oral presentations) that refer
to the Bacteriophage Program or programs that are approved by the JSC. For such reports, publications, and presentations, the disclosing Party will provide the other Party at least fifteen (15) calendar days for review of the proposed

other Party to postpone such submissions or presentations if necessary to provide the other Party with sufficient time to prepare and file any related Patent applications before the submission or presentation occurs, as appropriate. 

7.4 Terms of the Agreement. Each Party shall treat the terms of this Agreement as the Confidential Information of other Party,
subject to the exceptions set forth in Section 7.2. Notwithstanding the foregoing, each Party acknowledges that the other Party may be obligated to file a copy of this Agreement with the SEC, either as of the Effective Date or at some point
during the Term. Each Party shall be entitled to make such a required filing, provided that it requests confidential treatment of certain commercial terms and sensitive technical terms hereof to the extent such confidential treatment is reasonably
available to it. In the event of any such filing, the filing Party shall provide the other Party with a copy of the Agreement marked to show provisions for which the filing Party intends to seek confidential treatment and shall reasonably consider
and incorporate the other Party’s comments thereon to the extent consistent with the legal requirements governing redaction of information from material agreements that must be publicly filed. The other Party shall promptly provide any such

(k) Commercialization. Intrexon shall have the right to develop and Commercialize the Reverted Products itself or with one or more

(l) Confidential Information. Each Party shall promptly return, or at the other Party’s request destroy, any Confidential

differences which may arise between the Parties out of or in relation to or in connection with this Agreement, including, without limitation, any alleged failure to perform, or breach, of this
Agreement, or any issue relating to the interpretation or application of this Agreement, then upon the request of either Party by written notice, the Parties agree to meet and discuss in good faith a possible resolution thereof, which good faith
efforts shall include at least one in-person meeting between the Executive Officers of each Party. If the matter is not resolved within thirty (30) days following the written request for discussions, either Party may then invoke the provisions
of Section 11.2. 
 11.2 Arbitration. Any dispute, controversy, difference or claim which may arise between the
Parties, out of or in relation to or in connection with this Agreement (including, without limitation, arising out of or relating to the validity, construction, interpretation, enforceability, breach, performance, application or termination of this
Agreement) 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
substantive laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. 

11.4 Award. Any award to be paid by one Party to the other Party as determined by the arbitrator(s) as set forth above under
Section 11.2 shall be promptly paid in United States dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against the losing Party.
Each Party agrees to abide by the award rendered in any arbitration conducted pursuant to this Article 11, and agrees that, subject to the United States Federal Arbitration Act, 9 U.S.C. §§ 1-16, judgment may be entered upon the final
award in any United States District Court located in New York and that other courts may award full faith and credit to such judgment in order to enforce such award. The award shall include interest from the date of any damages incurred for breach of
the Agreement, and from the date of the award until paid in full, at a rate fixed by the arbitrator(s). With respect to money damages, nothing contained herein shall be construed to permit the arbitrator(s) or any court or any other forum to award
consequential, incidental, special, punitive or exemplary damages. By entering into this agreement to arbitrate, the Parties expressly waive any claim for consequential, incidental, special, punitive or exemplary damages. The only damages
recoverable under this Agreement are direct compensatory damages. 
 11.5 Costs. Each Party shall bear its own legal
fees. The arbitrator(s) shall assess his or her costs, fees and expenses against the Party losing the arbitration. 
 11.6
Injunctive Relief. Nothing in this Article 11 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or
other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. Specifically, the Parties agree that
a material breach by either Party of its obligations in Section 3.5 or Article 7 of this Agreement may cause irreparable harm to the other Party, for which damages may not be an adequate remedy. Therefore, in addition to its rights and remedies
otherwise available at law, including, without limitation, the recovery of damages for breach of this Agreement, upon an adequate showing of material breach of such Section 3.5 or Article 7, and without further proof of irreparable harm other
than this acknowledgement, such non-breaching Party shall be entitled to seek (a) immediate equitable relief, specifically including, but not limited to, both interim and permanent restraining orders and injunctions, without bond, and
(b) such other and further equitable relief as the court may deem proper under the circumstances. For the avoidance of doubt, nothing in this Section 11.6 shall otherwise limit a breaching Party’s opportunity to cure a material breach
as permitted in accordance with Section 10.2. 
 11.7 Confidentiality. The arbitration proceeding shall be
confidential and the arbitrator(s) shall issue appropriate protective orders to safeguard each Party’s Confidential Information. Except as required by law, no Party shall make (or instruct the arbitrator(s) to make) any public announcement with
respect to the proceedings or decision of the arbitrator(s)

without prior written consent of the other Party. The existence of any dispute submitted to arbitration, and the award, shall be kept in confidence by the Parties and the arbitrator(s), except as
required in connection with the enforcement of such award or as otherwise required by applicable law. 
 11.8
Survivability. Any duty to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason. 
 11.9 Jurisdiction. For the purposes of this Article 11, the Parties acknowledge their diversity and agree to accept the jurisdiction of any United States District Court located in New York for the
purposes of enforcing or appealing any awards entered pursuant to this Article 11 and for enforcing the agreements reflected in this Article 11 and agree not to commence any action, suit or proceeding related thereto except in such courts.

 11.10 Patent Disputes. Notwithstanding any other provisions of this Article 11, and subject to the provisions of
Section 6.2, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Intrexon Patents shall be submitted to a court of competent jurisdiction in the country in which such Patent was filed or
granted. 
 ARTICLE 12 
 GENERAL PROVISIONS 
 12.1 Use of Name.
No right, express or implied, is granted by this Agreement to either Party to use in any manner the name of the other or any other trade name or trademark of the other in connection with the performance of this Agreement, except that (a) either
Party may use the name of the other Party as required by regulations and in press releases accompanying quarterly and annual earnings reports approved by the issuer’s Board of Directors, and (b) Ampliphi may use the Intrexon Trademarks in
accord with licenses and restrictions set forth herein. 
 12.2 LIMITATION OF LIABILITY. NEITHER PARTY SHALL BE LIABLE TO
THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS
PARAGRAPH IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER ARTICLE 9, OR DAMAGES AVAILABLE FOR BREACHES OF THE OBLIGATIONS SET FORTH IN ARTICLE 7. 

12.3 Independent Parties. The Parties are not employees or legal representatives of the other Party for any purpose. Neither Party
shall have the authority to enter into any contracts in the name of or on behalf of the other Party. This Agreement shall not constitute, create, or in any way be interpreted as a joint venture, partnership, or business organization of any kind.

executors, heirs, representatives, administrators and permitted assigns of the Parties. Notwithstanding the foregoing, in the event that either Party assigns this Agreement to its successor in interest by way of merger, acquisition, consolidation,
