and not Precigen or its Affiliates information related to the Assigned Contracts that is required to be provided to Precigen or its Affialites under either any such Assigned Contract, and (y) MDACC and NCI, as applicable, permit Precigen (or
Intrexon) to appoint employees of Ziopharm (rather 

  
 21. 













 
than Precigen or Intrexon) to any joint steering committee under any such Assigned Contract. Upon the assent by NCI and MDACC to such request, Precigen shall appoint two individuals designated by
Ziopharm to any such joint steering committee. 
 3.3    Relinquishment of Rights and Obligations under Merck
Agreement. Precigen, on behalf of itself and its Affiliates (including Intrexon), hereby agrees to use diligent good faith efforts to obtain Ares Trading’s consent to the transfer of all of Ziopharm’s obligations and right, title and
interest in the Merck Agreement to Intrexon or its’ Affiliate. As between the Parties, from and after the Effective Date, Precigen agrees to perform all obligations of Ziopharm under the Merck Agreement (other than the obligation of exclusivity
set forth in Section 2.5 of the Merck Agreement), and, other than the obligation of exclusivity set forth in Section 2.5 of the Merck Agreement, Ziopharm shall not be responsible for any obligations under the Merck Agreement. For clarity,
Section 6.7 addresses Ziopharm’s sole ongoing payment obligation related to the payments owed to Ares Trading by Intrexon under Section 4.5(e) of the Merck Agreement. Nothing in this Agreement shall prohibit, and Ziopharm shall have
the right to negotiate a separate agreement with Ares Trading regarding obtaining rights to any intellectual property rights owned or controlled by Ares Trading relating to [***]. Promptly following the Effective Date, the Parties shall cooperate in
good faith, on Precigen’s request and at Precigen’s cost, to transfer all activities and rights related to CD33 under the Merck Agreement to Precigen, including the Existing Viral CD33 Trial, as set forth in Article 4.

consents required for the transfer of any such manufacturing related Information and, upon obtaining such consent, to transfer such manufacturing-related Information to Precigen to enable Precigen to advance CD33 and Accessory Material Agents.
Precigen shall reasonably cooperate with Ziopharm in connection with such consent and transfer. 

4.2    Technology Transfer Costs. Other than as may be agreed as a Transition Service hereunder, each Party
requesting transfer under Section 4.1 shall reimburse the other Party’s out-of-pocket expenses and FTE costs incurred to perform any technology transfer,
including any amounts paid in consideration for manufacturing support following such technology transfer. Each Party shall invoice the other Party on a monthly basis for the foregoing costs incurred by, and shall pay the amount invoiced within
thirty (30) days after the date of any such invoice. 

4.3    IL-12 Product Supply. 

(a)    Inventory Transfer. On Ziopharm’s reasonable request following the Effective Date, Precigen shall
transfer to Ziopharm or its designee some or all of its inventory of IL-12 Products (including all final product, drug substance, intermediates,
works-in-process, formulation materials, reference standards, drug product clinical reserve samples, packaged retention samples, and the like) that is then in the
possession or Control of Precigen or its Affiliates or sublicensees and in quantities reasonably requested by Ziopharm; provided that Ziopharm shall pay Precigen a price equal to Precigen’s historical cost plus [***] percent ([***]%) for any
such transferred IL-12 Product. 

  
 24. 

[***] = CERTAIN CONFIDENTIAL INFORMATION OMITTED 













 4.4    Assumption of Supply. On Ziopharm’s reasonable
request, Precigen shall, and shall cause its Affiliates and sublicensees to, reasonably cooperate with Ziopharm to facilitate orderly transition of the manufacture of IL-12 Products to Ziopharm or its
designee, including by assigning or amending as appropriate, upon request of Ziopharm, any agreements or arrangements with Third Party contract manufacturers to Ziopharm or, to the extent any such Third Party agreement or arrangement is not
assignable to Ziopharm, reasonably cooperating with Ziopharm to facilitate the entry by Ziopharm into a contract directly with such contract manufacturer(s). 

4.5    Transition Services. 

(a)    Transition Services. Precigen agrees to provide or cause to be provided to Ziopharm the services
listed on Exhibit C (the “Agreed Services”). Without limiting the foregoing, for a period of thirty (30) days following the Effective Date, Ziopharm shall have an opportunity to identify additional activities that
Precigen was performing with respect to the Licensed Product or the Development thereof as of the Effective Date that it would like Precigen to continue to perform under this Agreement for a specified period to enable the smooth transition of
activities in relation to the Licensed Products to Ziopharm. Upon identification of such activities by Ziopharm, Precigen shall reasonably determine whether it can continue to provide such services and, upon Precigen’s consent (which shall not
be unreasonably withheld), the Parties shall include such activities as Agreed Services hereunder and shall update Exhibit C to reflect the same. In no event shall any Agreed Services continue for a period longer than one (1) year
without the prior written consent of Precigen, which consent may be withheld at Precigen’s sole discretion. Without limiting the foregoing, for a period of one (1) year from the Effective Date (or such later date agreed by the Parties in
writing) (the “Transition Period”), Ziopharm may request that Precigen provide or continue to perform additional services related to any Licensed Product other than the Agreed Services, including, as applicable, the
(i) transition to Ziopharm or its designee some or all of any clinical or non-clinical trials for a Licensed Products in the Field and the activities related to or supporting such trials, (ii) the
continued conduct of any non-clinical or clinical trials for any Licensed Product in the Field, for a reasonable period of time requested by Ziopharm, (iii) ongoing services related to the manufacturing
of Licensed Products or (iv) the termination or wind-down of non-clinical or clinical trials; in each case as requested by Ziopharm, (the “Additional Services” and together with the
Agreed Services, the “Transition Services”). The Parties will negotiate terms for the provision of such Additional Services, provided that, for clarity, Precigen will not be obligated to provide any Additional Services unless
Precigen consents to do so, which consent may be withheld at Precigen’s sole discretion. Precigen agrees that is shall perform all Transition Services in the same or substantially similar manner, in all material respects, in which Precigen
generally performs or has performed similar services for its own product development business, provided that, unless otherwise agreed in writing (including as may be agreed and forth on Exhibit C for a specific Transition Service),
Precigen’s obligations to perform any Transition Services shall not extend beyond the Transition Period. 

(b)    Service Fees; Invoicing. Any and all service fees charged by Precigen, either directly, through its
Affiliates or through Third Party contractors shall (i) with respect to the Agreed Services, be set forth in Exhibit C and (ii) with respect to the Additional Services, be agreed by the Parties in writing. Unless otherwise agreed by
the Parties in writing, or as set forth 

  
 25. 













 
on Exhibit C with respect to payment for specific Agreed Services, Precigen will aggregate and invoice in a single invoice each month all of its service fees for any Transition Services
that are payable by Ziopharm for the Transition Services performed in such month. Precigen’s service fees will be invoiced monthly, in arrears, and Ziopharm shall pay all undisputed invoices within thirty (30) days of the date of receipt
of such invoice.  
 (c)    Third Party Consents. Without limiting Section 4.3(a) ,
Precigen shall use commercially reasonable efforts to obtain any waivers, permits, consents or similar approvals from any Third Parties or Governmental Authorities that are reasonably necessary for Precigen to perform or Ziopharm to receive the
Transition Services, as applicable (each a “Consent”). Ziopharm shall be solely responsible for the costs paid to any Third Party or Governmental Authority in respect of obtaining any such Consent; provided, however, that Precigen
shall notify Ziopharm in advance of any known costs associated with obtaining such Consents and obtain Ziopharm’s written approval of such consent fee prior to Precigen agreeing to pay such fee and prior to Ziopharm being liable for any such
fee. If, after thirty (30) days using its commercially reasonable efforts, or such longer period as may be requested by Ziopharm, Precigen is unable to obtain any Consent, the Parties shall work together in good faith to agree upon a
commercially reasonable alternative arrangement in respect of such Transition Service for which a Consent is required but has not been obtained to the maximum extent possible and shall then perform any such alternative as a Transition Service
hereunder. 
 (d)    Third Party Contracts. Precigen shall, to the extent reasonably possible utilize any
Third Party contracts on behalf of Ziopharm in the performance of the Transition Services, and Ziopharm agrees to comply with the terms of any Third Party contract to the extent relevant to the receipt of a Transition Service, provided that Ziopharm
has received prior written notification of the terms of such Third Party contract, and provided, further, that, following receipt of notification of such terms, Ziopharm may opt to not receive the relevant Transition Service rather than comply with
such terms. Where a Third Party contract is required in order for the provision of the Transition Services and such Third Party contract expires or is terminated by the relevant Third Party, then Precigen shall use all reasonable efforts to perform
the relevant Transition Services itself or to provide a substitute of similar (but no lower) quality and reputation, with the costs of retaining such substitute borne solely by Precigen, unless otherwise agreed.  

(e)    Intellectual Property. Ownership of all inventions and intellectual property developed by or on
behalf of Precigen in the performance of transition services shall be determined in accordance with Section 7.1(c). 

(f)    Early Termination. Prior to the expiration of the Transition Period and subject to any limitations
set forth on Exhibit C with respect to specific Transition Services, Ziopharm may elect to terminate Precigen’s provision of certain of the Transition Services by delivering written notice of such election to Precigen. Such termination
of the applicable Transition Services will be effective no earlier than thirty (30) calendar days following Precigen’s receipt of such notice, unless Precigen consents to a shorter period. Upon any termination or reduction of any
Transition Service and subject to any rights or obligations that have accrued prior to termination, neither Party shall have any further obligation to the other Party in respect of the Transition Services that have been terminated. 

  
 26. 













 4.6    Regulatory or Third Party Action or Inspection.
Each Party shall immediately notify the other Party as promptly as reasonably possible following becoming aware of any Regulatory Authority inspections relating to (a) in the case of Precigen, any of its products that utilizes or incorporates
any technology that is also used or incorporated in any Licensed Product, and (b) in the case of Ziopharm, a Licensed Product that, in either case of (a) or (b) is reasonably likely to have an impact on the other Party (each of
(a) and (b), a “Reporting Product” of such Party). To the extent permitted by applicable Law, each Party shall have the right to be present at any such inspections and shall have the opportunity to provide, review and comment
on any responses that may be required, in each case, to the extent applicable to such Party’s Reporting Product(s). In the event a Party does not receive prior notice of any such inspection, the Party shall notify the other Party as soon as
practicable after such inspection and shall provide the other Party with copies of all materials, correspondence, statements, forms and records received or generated pursuant to any such inspection to the extent permitted by applicable Law and to
the extent related to such other Party’s Reporting Product(s). In addition to such obligations with respect to Regulatory Authority inspections, each Party shall immediately notify the other Party of any material Information it receives
regarding any threatened or pending action or communication by or from any Regulatory Authority that is reasonably likely to materially and adversely affect the regulatory status of any Reporting Product(s) of such other Party; provided, that such
Party is permitted to disclosure such material Information, including under applicable Law.. 
 4.7    Rights
of Reference. Within sixty (60) days following the Effective Date, the Parties will negotiate in good faith and agree in writing to a separate agreement setting forth the terms pursuant to which each Party would grant to the other Party the
right to reference and use the Drug Master Files (DMFs) or other regulatory filings of such Party (the “Regulatory Exchange Agreement”). The Parties acknowledge that the Regulatory Exchange Agreement shall be subject to the
agreement of the Parties in all respects, including with respect to the permitted scope of such reference and use rights, including with respect to specific products, development stages, fields of use, specific entities or persons and territories.

Ziopharm’s review and comment prior to the submission of such proposed filings and correspondence. Precigen shall confer with Ziopharm and incorporate Ziopharm’s comments prior to submitting such filings and correspondence, provided, that
Ziopharm’s comments do not require Precigen to take any action in connection with the Licensed Patents that could reasonably be expected to adversely affect Precigen’s or its Affiliate’s Development or Commercialization of
(i) products (other than Licensed Products) claimed by such Licensed Patent inside or outside the Field in the Territory or (ii) Licensed Products claimed by such Licensed Patent outside the Field in the Territory (a
“Precigen Impact Situation”). If in either Party’s opinion, a Precigen Impact Situation could arise, such Party will promptly notify the other Party and the Parties shall discuss in good faith. Precigen shall have final
decision authority with respect to whether or not to incorporate such comments. 
 (b)    New Patent

Infringement. 
 (b)    Enforcement Rights. For any Patent Infringement, each Party shall share with the
other Party all Information available to it regarding such actual or alleged infringement. With respect to any Patent Infringement with a product that competes with an Exclusive Product in the Field (a “Product Infringement”),
Ziopharm shall have the first right, but not the obligation, to bring an appropriate suit or take other action against any person or entity engaged in, or to defend against, such Product Infringement, at Ziopharm’s cost and expense. Ziopharm
shall not settle any such suit or action in any manner that would reasonably be expected to (i) create a Precigen Impact Situation anywhere in the Territory, (ii) require Precigen to incur any liability or (iii) require Precigen to
make any payments, in each case without the prior written consent of Precigen. If Ziopharm does not, within one hundred eighty (180) days after its receipt or delivery of notice under Section 7.5(a), commence a suit to enforce the Licensed
Patents against such Product Infringement, take other action to terminate such Product Infringement or initiate a defense against such Product Infringement, Precigen shall have the right, but not the obligation, to commence such a suit or take such
an action or defend against such Product

enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by applicable Laws to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status
and progress of such enforcement efforts and shall reasonably consider the other Party’s comments on any such efforts. The non-enforcing Party shall be entitled to separate representation in such matter
by counsel of its own choice and at its own expense, but such Party shall at all times cooperate fully with the enforcing Party. 

(d)    Expenses and Recoveries. The Party bringing or defending a claim, suit or action under
Section 7.5(b) shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages in such claim, suit or action, such recovery shall be allocated first to the
reimbursement of any expenses incurred by the Parties in such litigation, and any remaining amounts shall be allocated as follows: (i) if Ziopharm is the enforcing or defending Party, the remaining amounts will be retained by Ziopharm, except
that all such amounts shall be attributable to lost sales of Licensed Products shall be included in Net Sales subject to the royalty payment by Ziopharm to Precigen pursuant to Section 6.5(a) or Section 6.5(b), as applicable, and
(ii) if Precigen is the enforcing or defending Party, Precigen shall retain all amounts.

applicable Licensed Patent, Precigen shall promptly provide Ziopharm with all information reasonably required by Ziopharm to list such Licensed Patent in the Orange Book maintained by the FDA or similar or equivalent patent listing source, if any,
in other countries in the Territory. Ziopharm shall have the sole right to determine which Licensed Patent or other Patent shall be included in the Orange Book for Licensed Products. 

7.7    Patent Term Extensions. Precigen will cooperate with Ziopharm, at Ziopharm’s request, in
seeking and obtaining patent term extensions (including any pediatric exclusivity extensions as may be available) or supplemental protection certificates or their equivalents in any country with respect to any Exclusive Royalty-Bearing Products. If
elections with respect to obtaining such patent term extensions are to be made, Ziopharm shall have the sole right to make such elections.

7.9    Trademarks. 

(a)    Existing Trademarks. Within thirty (30) days of the Effective Date, the Parties shall enter into

Commercialization of any Licensed Products hereunder prior to the use thereof. 
 (b)    New Product
Marks. Ziopharm and its Affiliates and Sublicensees shall have the right to brand the Licensed Products in the Territory using any Trademarks it determines appropriate for the Licensed Products, which may vary by country or within a country (the
“New Product Marks”), provided that Ziopharm shall not, and shall ensure that its Affiliates and Sublicensees will not, make any use of the trademarks or house marks of Precigen (including Precigen’s corporate name) or
any trademark confusingly similar thereto. As between the Parties, Ziopharm shall own all rights in the New Product Marks and shall register and maintain, in its discretion and at its own cost and expense, the New Product Marks in the countries and
regions in the Territory that it determines to be appropriate. Ziopharm shall have the sole right, in its discretion and at its expense, to defend and enforce the New Product Marks. Notwithstanding the foregoing, Ziopharm shall not rebrand any
portion of the Licensed Intellectual Property that is the subject of a Trademark Controlled by Precigen or its Affiliates as of the Effective Date and set forth on Exhibit G hereto.

TERM AND TERMINATION 

11.1    Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated
pursuant to this Article 11 shall remain in effect on a Licensed Product-by-Licensed Product and
country-by-country basis, until the expiration of the Royalty Term of such Licensed Product in such country (the “Term”). Upon the expiration of the
Royalty Term for a Licensed Product in a particular country, the licenses granted by Precigen to Ziopharm under Section 2.1(a), Section 2.1(b) and Section 7.9(a) with respect to such Licensed Product and related Trademarks and such
country shall become fully-paid, royalty free and irrevocable. 
 11.2    Unilateral Termination by Ziopharm.
Ziopharm may terminate this Agreement, on a country-by-country or Program-by-Program
basis or in its entirety, for any or no reason upon ninety (90) days’ written notice to Precigen. 

11.3    Termination by Either Party for Breach. 

(a)    Breach. Subject to Section 11.3(b), each Party shall have the right to terminate this Agreement
upon written notice to the other Party if such other Party materially breaches its obligations under this Agreement and, after receiving written notice from the non-breaching Party identifying such material
breach in reasonable detail, fails to cure such material breach within sixty (60) days from the date of such notice; provided that if such breach is not reasonably capable of cure within such sixty
(60)-day period, the breaching Party may submit a reasonable cure plan prior to the end of such sixty (60)-day period, in which case the other Party shall not have the
right to terminate this Agreement for so long as the breaching Party is using Commercially Reasonable Efforts to implement such cure plan. 

(b)    Disputed Breach. If the alleged breaching Party disputes in good faith the existence or materiality
of a breach specified in a notice provided by the other Party in accordance with Section 11.3(a), and such alleged breaching Party provides the other Party notice of such dispute within such sixty
(60)-day period, then the non-breaching Party shall not have the right to terminate this Agreement under Section 11.3(a) unless and until the arbitrators, in
accordance with Section 12.2, has determined that the alleged breaching Party has materially breached the Agreement and that such Party fails to cure such breach within sixty (60) days following such arbitrators’ decision. During the
pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder. Except with respect to breaches of payment obligations, the
Parties agree that a breach with respect to a Licensed Product shall not itself be deemed to be a breach with respect to other Licensed Products and any termination of this Agreement shall be limited to the Licensed Product or Licensed Products for
which a Party breached its obligations hereunder. Nothing in this Section 11.3 shall limit a Party’s ability to seek remedies available under this Agreement in law or equity. 

11.4    Effect of Termination. Upon any termination (but not expiration) of this Agreement, with respect to
one or more countries, one or more Programs, or in its entirety, all licenses granted to Ziopharm under this Agreement shall terminate for the applicable terminated 

  
 48. 













 
countries or applicable Programs (or, if this Agreement is terminated in its entirety, for the Territory), and the following shall apply: 

(a)    Assignment and License of Exclusive Product Patents. Unless the termination was by Ziopharm pursuant
to Section 11.3, Ziopharm shall assign to Precigen all of Ziopharm’s right, title, and interest in and to any Patents owned by Ziopharm to the extent solely and exclusively Covering the Exclusive Products for use in the Field. In the event
Ziopharm owns or Controls Patents that Cover the Exclusive Products for use in the Field and other compounds technologies or uses for the Exclusive Products outside of the Field, then Ziopharm shall not assign such Patents to Precigen, but shall,
and hereby does, grant to Precigen an exclusive, irrevocable, royalty-free license to use such Patents solely to Develop and Commercialize such Exclusive Products for use in the Field in the form that such Exclusive Products exist as of the
effective date of termination (such Exclusive Products, the “Terminated Products”). The assignments and licenses granted to Precigen pursuant to this Section 11.4(a) are subject to Precigen paying Ziopharm royalties on the Net
Sales (as such term is modified to apply to sales by Precigen, its Affiliates and sublicensees) of all Terminated Products in the Field at a rate of [***] percent ([***]%), provided that once the cumulative royalties for all Terminated Products paid
by Precigen pursuant to this Section 11.4(a) equal [***] percent ([***]%) of Ziopharm’s reasonable documented costs and expenses incurred in the Research, Development, manufacture and Commercialization of Terminated Products during the
Term up to the termination date with respect to such Terminated Products. Such royalty payments pursuant to this Section 11.4(a) shall be paid on a Terminated
Product-by-Terminated Product and country-by-country basis from the First Commercial Sale
of such Terminated Product in such country until the later of (i) the expiration of the last to expire Valid Claim (as such term is modified to apply to the Patents assigned or licensed to Precigen) in such country that Covers such Terminated
Product (or any intermediate or component thereof) and (ii) twelve (12) years after the First Commercial Sale of such Terminated Product in such country. Provided such Termination is not due to breach by Ziopharm under this Agreement. 

(b)    Negotiation Right. In addition, Ziopharm shall negotiate in good faith with Precigen,
and shall assist Precigen in any good faith negotiations with applicable Third Parties, to permit Precigen the opportunity to obtain license to any Patents owned by Ziopharm or Third Parties Covering the Exclusive Products but that was not assigned
or licensed to Precigen pursuant to Section 11.4(a), in which case the Parties may enter into a separate agreement or an amendment to this Agreement to reflect any such agreed terms. 

11.5    Survival. Termination or expiration of this Agreement shall not affect any rights or obligations of
the Parties under this Agreement that have accrued prior to the date of termination or expiration. Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement: Articles 1 (to the
extent definitions are used in the following sections or portions thereof), 9, 10, 12, and 14 (other than Section 14.5) and individual Sections: 2.7, 3.2 (solely with respect to any rights that have accrued prior to expiration or termination),
3.3 (with respect to Ziopharm’s responsibility under the Merck Agreement), 3.4, 4.5(b) (with respect to Transition Services properly performed prior to the effective date of termination or expiration), 6.2 (solely to the extent required to make
final reconciliations on Operating Profits (or Losses) incurred prior to expiration or termination), 6.4 (solely with respect to Sublicensing Income received prior to the effective date of termination or


  
 49. 

[***] = CERTAIN CONFIDENTIAL INFORMATION OMITTED 













 
expiration), 6.5 (solely to the extent required to make final reconciliations on Net Sales of Exclusive Royalty-Bearing Products achieved prior to expiration or termination), 6.7 (solely to the
extent required to make final reconciliations of amounts owed prior to the effective date of termination or expiration), 6.8-6.11 (solely as applicable to payments made following termination or expiration),
7.1, 7.2, 8.4, 11.1, 11.4 and 11.5. If this Agreement is terminated with respect to a given Licensed Product, but not in its entirety, then following such termination the foregoing provisions of this Agreement shall remain in effect with respect to
the Licensed Product(s) for which the termination is applicable (to the extent they would survive and apply in the event the Agreement expires or is terminated in its entirety) and all provisions not surviving in accordance with the foregoing shall
terminate with respect to the relevant Licensed Product for which the termination applies, as applicable, upon the effective date of termination thereof. 

ARTICLE 12 
 DISPUTE
RESOLUTION 
 12.1    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 the JDC), 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 (each, a “Dispute”), 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 12.2. For the avoidance of doubt, any disputes, controversies or differences arising from the JDC pursuant to Article 5 shall be resolved solely in accordance with Article 5. 

12.2    Arbitration. Any Dispute that is not resolved pursuant to Section 12.1 shall, subject to
Section 12.10, be shall resolved by binding arbitration administered by the American Arbitration Association (“AAA”) (or its successor entity) in accordance with the then current Commercial Rules of the American Arbitration
Association including the Procedures for Large, Complex Commercial Disputes (including the Optional Rules for Emergency Measures of Protection) (the “AAA Rules”), except as modified in this Agreement, which AAA Rules are deemed to
be incorporated by reference into this clause. The decision rendered in any such arbitration will be final, binding and unappealable. The arbitration shall be conducted by a panel of three (3) arbitrators appointed in accordance with the AAA
Rules, none of whom shall be a current or former employee or director, or a then-current stockholder, of either Party, their respective Affiliates or any Sublicensee. The place of arbitration shall be New York, New York, U.S., and all proceedings
and communications shall be in English. It is the intention of the Parties that discovery, although permitted as described herein, will be limited except in exceptional circumstances. The arbitrators will permit such limited discovery necessary for
an understanding of any legitimate issue raised in the arbitration, including the production of documents. No later than thirty (30) days after selection of the arbitrators, the Parties and their representatives shall hold a preliminary meeting
with the arbitrators, to mutually agree upon and thereafter follow procedures seeking to assure that the arbitration will be concluded within six (6) months from such meeting. Failing any such mutual agreement, the arbitrators will design and
the Parties shall follow procedures to such effect. 

  
 50. 













 12.3    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.

 12.4    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 12.2 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 Section 12.4, 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. 

12.5    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. 
 12.6    Injunctive Relief. Nothing in this
Article 12 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. For the avoidance of doubt, nothing in this Section 12.6 shall
otherwise limit a breaching Party’s opportunity to cure a material breach as permitted in accordance with Section 11.3. 

12.7    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. 
 12.8    Survivability. Any duty
to arbitrate under this Agreement shall remain in effect and be enforceable after termination of this Agreement for any reason. 

  
 51. 













 12.9    Jurisdiction. For the purposes of this Article 12,
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 12 and for enforcing the
agreements reflected in this Article 12 and agree not to commence any action, suit or proceeding related thereto except in such courts. 

12.10    Patent and Trademark Disputes. Notwithstanding any other provisions of this Article 12, any
dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Licensed Patents shall be submitted to a court of competent jurisdiction in the country in which such Patent was filed or granted.

(a)    Intrexon is the legal and beneficial owner of the Preferred Shares with good and valid title thereto, free

 52. 













 
by Intrexon and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary corporate action, and no further consent or authorization of Intrexon or
its board of directors, stockholders or other governing body is required. When executed and delivered by Intrexon, this Agreement shall constitute a valid and binding obligation of Intrexon, enforceable against Intrexon in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditor’s rights
and remedies or by other equitable principles of general application. 
 (c)    The execution, delivery and
performance of this Agreement by Intrexon and the consummation by Intrexon of the transactions contemplated hereby do not and will not (i) violate any provision of Intrexon’s charter or organizational documents (ii) conflict with, or
constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, mortgage, deed of trust, indenture,
note, bond, license, lease agreement, instrument or obligation to which Intrexon is a party or by which Intrexon’s properties or assets are bound, or (iii) result in a violation of any federal, state, local or foreign statute, rule,
regulation, order, judgment or decree (including federal and state securities laws and regulations) applicable to Intrexon or by which any property or asset of Intrexon are bound or affected, except, in all cases, other than violations (with respect
to federal and state securities laws) above, for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, materially and adversely affect Intrexon’s ability
to perform its obligations under this Agreement. 
 13.4    Termination of Purchase Agreement. Effective
immediately, Ziopharm and Intrexon hereby terminate the 2011 Stock Purchase Agreement and acknowledge and agree that the 2011 Stock Purchase Agreement shall have no further force or effect and that all of the benefits, rights, obligations and

 ARTICLE 14 

MISCELLANEOUS 

14.1    Entire Agreement; Amendment. This Agreement, including the Exhibits hereto, and the Related
Agreements sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto with respect to the subject matter hereof and
supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof. There are no covenants, promises, agreements, warranties, representations, conditions or
understandings, either oral or written, between the Parties other than as are set forth in this Agreement or the Related Agreements. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless
reduced to writing and signed by an authorized officer of each Party. 
 14.2    Rights in Bankruptcy.

 (a)    To the extent permitted under applicable Law, all rights and licenses granted under or pursuant to this
Agreement by one Party to the other are, for all purposes of Title 11 of the United States Code (“Title 11”), licenses of rights to “intellectual property” as defined in Title 11, and, in the event that a case under Title
11 is commenced by or against either Party (the “Bankrupt Party”), the other Party shall have all of the rights set forth in Section 365(n) of Title 11 to the maximum extent permitted thereby. All rights of the Parties under
this Section 14.2 and under Section 365(n) of Title 11 are in addition to and not in substitution of any and all other rights, powers, and remedies that each party may have under this Agreement, Title 11, and any other applicable Laws. The
non-Bankrupt Party shall have the right to perform the obligations of the Bankrupt Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the non-Bankrupt Party shall release the Bankrupt Party from any such obligation or liability for failing to perform it. 

(b)    The Parties agree that they intend the foregoing non-Bankrupt Party
rights to extend to the maximum extent permitted by law and any provisions of applicable contracts with Third Parties, including for purposes of Title 11, (i) the right of access to any intellectual property (including all embodiments thereof) of
the Bankrupt Party or any Third Party with whom the Bankrupt Party contracts to perform an obligation of the Bankrupt Party under this Agreement, and, in the case of the Third Party, which is necessary for the Development, Regulatory Approval and
manufacture of Licensed Products and (ii) the right to contract directly with any Third Party described in (i) in this sentence to complete the contracted work. 

(c)    Any intellectual property provided pursuant to the provisions of this Section 14.2 shall be subject to
the licenses set forth elsewhere in this Agreement and the payment obligations of this Agreement, which shall be deemed to be royalties for purposes of Title 11. 

14.3    Force Majeure. Both Parties shall be excused from the performance of their obligations under this
Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure


  
 54. 













 
continues and the nonperforming Party takes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties,
including an act of God, war, civil commotion, terrorist act, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by
fire, earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such failure could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a
skilled and experienced person engaged in the same type of undertaking under the same or similar circumstances). Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting
such Party. If a force majeure persists for more than ninety (90) days, then the Parties will discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such force
majeure. 
 14.4    Notices. Any notice required or permitted to be given under this Agreement shall be in
writing, shall specifically refer to this Agreement, and shall be addressed to the appropriate Party at the address specified below or such other address as may be specified by such Party in writing in accordance with this Section 14.4, and
shall be deemed to have been given for all purposes (a) when received, if hand-delivered or sent by confirmed facsimile or a reputable courier service, or (b) five (5) Business Days after mailing, if mailed by first class certified or
registered airmail, postage prepaid, return receipt requested.

14.5    No Strict Construction; Headings. This Agreement has been prepared jointly by the Parties and shall
not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The headings of each Article and
Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. Except where the context otherwise requires, the
use of any gender shall be applicable to all genders, and the word “or” is used in the inclusive sense (and/or). The term “including” as used herein means including, without limiting the generality of any description preceding
such term. 
 14.6    Assignment. Neither Party may assign or transfer this Agreement or any rights or
obligations hereunder without the prior written consent of the other, which consent shall not be unreasonably withheld or delayed, except that a Party may make such an assignment or transfer without the other Party’s consent (a) to its
Affiliates, (b) to a Third Party in connection with the transfer or sale of all or substantially all of the business or assets of such Party to which this Agreement relates, whether by merger, consolidation, divesture, restructure, sale of
stock, sale of assets or otherwise or (c) to a Third Party in connection with the transfer or sale of all or substantially all of the business or assets of such Party relating to a Licensed Product, whether by merger, consolidation, divesture,
restructure, sale of stock, sale of assets or otherwise. Any successor or assignee of rights and/or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights and/or obligations. Any permitted
assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 14.6 shall be null, void and of no legal effect. 

14.7    Performance by Affiliates. Each Party may discharge any obligations and exercise any right hereunder
through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with
such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first
proceed against such Party’s Affiliate. 
 14.8    Further Actions. Each Party agrees to execute,
acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 

  
 56. 













 14.9    Severability. If any one or more of the provisions
of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining
provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized. 

14.10    No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a
particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter
for a particular period of time. 
 14.11    Independent Contractors. Each Party shall act solely as an
independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners,
principal and agent, or joint-venture partners between the Parties. 
 14.12    Counterparts. This
Agreement may be executed in one (1) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

14.13    Intrexon Guarantee. Intrexon hereby unconditionally guarantees and undertakes to Ziopharm that
Precigen will duly and punctually observe and perform all the undertakings, covenants and obligations of Precigen under this Agreement and under any agreements between the Parties (or any of them) which are expressly supplemental to this Agreement
or which this Agreement requires to be executed (the “Obligations”) to the intent that if Precigen (or any assignee or successor in interest thereto) shall fail for whatever reason so to observe and perform any Obligations, Intrexon
shall be liable to perform the same in all respects as if Intrexon was the party principally bound thereby in place of Precigen on demand from Ziopharm, provided that Intrexon shall be deemed to have any defenses or excuses for nonperformance that
Precigen would have had to such Obligations. The liability of Intrexon under this Agreement shall be as primary obligor as regards Ziopharm and not merely as surety and no modification, variation or addition to any of the Obligations, no time
or other indulgence given by Ziopharm to Precigen nor any neglect, failure or forbearance on the part of Ziopharm to enforce the performance or observance of any of the Obligations shall in any way release, lessen or affect the liability of
Intrexon. This is a continuing guarantee and Intrexon’s undertakings under this Agreement shall remain in full force and effect until the earlier of (a) a Qualified IPO of Precigen, (b) a Qualified Change of Control, (c) a
Qualified Private Financing, and (d) final performance in full of the Obligations. In addition, until the earlier of (i) the termination of this guarantee or (ii) the end of the Term, Intrexon will not divest, restructure,
reorganize or reclassify Precigen with any intent in whole or in part to avoid, reduce or eliminate its obligations under this Agreement. As used herein, “Qualified IPO” means an initial public offering of shares of
Precigen’s common stock through which Precigen raises at least [***] dollars ($[***]) and lists Precigen’s common stock for sale in the public market; “Qualified Change of Control” means a transaction or series of
transactions through which Intrexon controls less than fifty percent (50%) of the equity of Precigen provided that Precigen or its parent entity following such transaction or transactions has 

  
 57. 

[***] = CERTAIN CONFIDENTIAL INFORMATION OMITTED 













 
a market cap of at least [***] dollars ($[***]), and “Qualified Private Financing” means a transaction or series of transactions involving the sale of shares of Precigen’s
stock (common or preferred) to Third Parties through which Precigen raises at least [***] dollars ($[***]).

 Ziopharm and Precigen Redefine Relationships, 

Announce New License Agreement 

Ziopharm to Host Conference Call Today at 8 a.m. 

BOSTON and GERMANTOWN, MD, October 9, 2018 – Ziopharm Oncology, Inc. (Nasdaq: ZIOP) and Precigen, Inc., a wholly-owned
subsidiary of Intrexon Corporation (Nasdaq: XON), today announced a new definitive license agreement to replace all existing agreements between the companies that will provide Ziopharm with certain exclusive and
non-exclusive rights to technology controlled by Precigen, Inc. 
 Through the new agreement, Ziopharm will
primarily focus its resources on developing its Controlled IL-12 and Sleeping Beauty (SB) T-cell receptor (TCR) platform technologies which have the capability to
treat solid tumors, while Intrexon further establishes Precigen as a therapeutics company concentrating on immuno-oncology, autoimmune and infectious disease therapies. Both companies will be better positioned to independently focus on their
respective platforms and markets with full developmental and financial controls. 
 With this exclusive license, Ziopharm now has full developmental control
and exclusivity utilizing Sleeping Beauty for TCRs targeted towards neoantigens and public antigens. The existing Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute related to SB-generated T cells expressing TCRs to target neoantigens buried within solid tumors will be transferred to Ziopharm, and Ziopharm will maintain this exclusive relationship with the NCI for this program. Ziopharm
will build on its IL-12 platform utilizing Precigen’s RheoSwitch® gene switch with both the existing human adenovirus program and now with rights
to pursue next-generation viral technologies. Using the SB system, Ziopharm will continue to advance its CD19-specific chimeric antigen receptor (CAR) program, while retaining rights to a second, unnamed CAR target. Precigen gains exclusive rights
for all other CAR-T therapies, including CD33-specific CAR-T therapies, subject to the agreement with Merck KGaA. 

“This is a new day for Ziopharm, as we have the power and flexibility to advance IL-12 and Sleeping
Beauty-generated TCRs ,” said Ziopharm Chief Executive Officer Laurence Cooper, M.D., Ph.D. “We now have focused the company on the two platforms to drive the most shareholder value and transitioned a significant portion of our CAR-T program to Precigen. The ability of both Ziopharm and Precigen to autonomously execute their respective operating plans on their independent platforms, while sharing in future economics, enables both parties
to undertake more efficient ‘divide and conquer’ drug-development plans to the benefit of all constituents.” 












 In partial consideration for the termination of the former agreements, in addition to the grant of the
revised limited exclusive license, the companies agree that Ziopharm will retire all outstanding shares of its Series 1 Preferred Stock held by Intrexon, including any accrued dividends, valued at approximately $156.9 million, as of Sept. 30,
2018. Additionally, the companies have terminated Intrexon’s contractual right to a seat on Ziopharm’s board. Randal J. Kirk, Chairman and Chief Executive Officer of Intrexon, who has served as a director on the board of Ziopharm since
2011, has stepped down from that position, effective immediately, and Ziopharm plans to fill all vacant seats in the near term. 
 “In 2011 with
Ziopharm, we entered into our first exclusive collaboration and therewith granted a field that was far broader than any other. Today’s announcement is about seeing Ziopharm’s tighter focus and about our desire to invest in Precigen. We
believe that Ziopharm will succeed under the license to develop and bring to market important new cancer therapeutics, and we look forward to enjoying benefits from these while we continue our investments in Precigen,” commented Mr. Kirk.

 Ziopharm will receive a low single digit, capped royalty on Precigen products in the field of point-of-care (P-O-C) CAR T-cell therapies. Precigen will receive milestone payments on
late-stage regulatory events as well as commercial royalties in the low to high single-digit range for certain CAR and IL-12 targets that Ziopharm develops. Precigen will receive capped commercial royalties in
low- to mid-single digits for the TCR products that Ziopharm develops. Further details on the terms of the transaction will be available within SEC filings respectively
filed by Intrexon and Ziopharm. 
 Ziopharm Clinical Programs Update 

Ziopharm today updated guidance on the timing of its response to the request for more information from the U.S. Food and Drug Administration (FDA) regarding
the clinical hold placed on the investigational new drug (IND) application for its third-generation Phase 1 trial to evaluate CD19-specific CAR-T therapies under P-O-C technology. Ziopharm expects to respond to the FDA’s request for information in the second half of 2019. 

Ziopharm also affirmed its guidance on the planned Phase 1 trial to evaluate SB-modified TCRs to treat solid tumors. As disclosed in Ziopharm’s second
quarter business update, the IND application for this Phase 1 trial, which is being led by and conducted at the National Cancer Institute, remains on track to be submitted in the fourth quarter of 2018 followed by enrollment of patients beginning in
2019, pending regulatory clearance.
