 2.3 General Committee Membership and Procedure. 

(a) Membership. For each Committee, each Party shall designate an equal number of representatives who are employees of such Party
or an Affiliate of such Party (not to exceed three (3) for each Party) with appropriate expertise to serve as members of such Committee (and Third Security shall be deemed to be an Affiliate of Intrexon solely for purposes of this
Section 2.3). Each representative may serve on more than one 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. 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 ZIOPHARM
selecting the chairperson first for the JSC, CRC 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 thirty (30) 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. 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 ZIOPHARM 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 (including without limitation in any Working Group). 
 (c) Meeting Agendas. Each Party will disclose to the other proposed agenda items along with appropriate information at least seven (7) 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) Working Groups. From time to time, each Committee may establish and delegate duties to other committees, sub-committees or
directed teams (each, a “Working Group”) on an “as-needed” basis to oversee particular projects or activities. Each such Working Group shall be constituted and shall operate as the applicable Committee determines;
provided, that each Working Group shall have equal representation from each Party. Each Working Group and its activities shall be subject to the oversight, review and approval of, and shall report to, the Committee that established such Working
Group. In no event shall the authority of the Working Group exceed that specified for the relevant Committee in this Article 2. 

(e) 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 by the mutual consent of the Parties and shall not be a substitute for the rights of the Parties. Without

ARTICLE 3 

LICENSE GRANTS 
 3.1 Licenses to ZIOPHARM. 
 (a) Subject to the terms and conditions
of this Agreement, Intrexon hereby grants to ZIOPHARM a license under the Intrexon IP to research, develop, use, import, make, have made, sell, and offer for sale ZIOPHARM Products in the Field in the Territory. Such license shall be exclusive (even
as to Intrexon) with respect to any clinical development, selling, offering for sale or other Commercialization of ZIOPHARM Products in the Field, and shall be otherwise non-exclusive. 

(b) Subject to the terms and conditions of this Agreement, Intrexon hereby grants to ZIOPHARM a non-exclusive, royalty-free
license to use and display the Intrexon Trademarks, solely in connection with the Commercialization of ZIOPHARM Products, in the promotional materials, packaging, and labeling for ZIOPHARM Products, as provided under and in accordance with
Section 4.9. 
 3.2 Sublicensing. Except as provided below, ZIOPHARM 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 ZIOPHARM Products, in each case except with Intrexon’s written
consent, which written consent may be withheld in Intrexon’s sole discretion. Notwithstanding the foregoing, ZIOPHARM may transfer, to the extent reasonably necessary, Intrexon Materials to a Third Party contractor performing post-API
fill/finish responsibilities for ZIOPHARM Products, and may grant any sublicenses necessary to enable such Third Party to perform such activities. In addition, ZIOPHARM shall not sublicense the rights granted under Section 3.1 to an Affiliate,
or transfer the Intrexon Materials to any Affiliate, or otherwise grant any Affiliate the right to research, develop, use, or commercialize ZIOPHARM Products, in each case except with Intrexon’s written consent, which written consent shall not
be unreasonably withheld or delayed. In the event that Intrexon consents to any such grant or transfer to an Affiliate, ZIOPHARM 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 ZIOPHARM), including any payment obligations owed to Intrexon hereunder. None of the enforcement rights under the Intrexon Patents
that are

granted to ZIOPHARM 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. 
 3.3 No Non-Permitted Use. ZIOPHARM 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.

 3.4 Exclusivity. Intrexon and ZIOPHARM mutually agree that, under the channel partnership established by this
Agreement, it is intended that the Parties will be exclusive to each other in the Field. To this end, 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, 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 sale in
the Field, outside of the Cancer Program. Further, neither ZIOPHARM nor its Affiliates shall pursue (either by itself or with a Third Party or Affiliate) the research, development or commercialization of any product for purpose of sale in the Field,
outside of the Cancer Program. 
 3.5 Off Label Use. For purpose of clarity, (a) following the First Commercial Sale
of a ZIOPHARM Product, the use by direct or indirect purchasers or other users of ZIOPHARM Products outside the Field (i.e. “off label use”) shall not constitute a breach by ZIOPHARM of the terms of Section 3.3 or 3.4, provided that
neither ZIOPHARM nor its Affiliate (nor any Third Party under contract with either of them) marketed or promoted ZIOPHARM Products for such off-label use; and (b) following the first commercial sale of a product by Intrexon, an Intrexon
Affiliate, or a Third Party sublicensee, collaborator, or partner of Intrexon, the use by direct or indirect purchasers or other users of such products in the Field (i.e. “off label use”) shall not constitute a breach by Intrexon of the
terms of Section 3.4, provided that neither Intrexon nor its Affiliate (nor any Third Party under contract with either of them) marketed or promoted such products for such off-label use. 

3.6 No Prohibition on Intrexon. Except as explicitly set forth in Sections 3.1 and 3.4, nothing in this Agreement shall prevent
Intrexon from practicing or using the Intrexon Materials, Intrexon Channel Technology, and Intrexon IP for any purpose, and to grant to Third Parties the right to do the same. Without limiting the generality of the foregoing, ZIOPHARM acknowledges
that Intrexon has all rights, in Intrexon’s sole discretion, to make the Intrexon Materials, Intrexon Channel Technology (including any active pharmaceutical ingredient used in a ZIOPHARM Product), and Intrexon IP available to Third Party
channel partners for use in fields outside the Field. 
 3.7 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 directed to Intrexon’s in vivo expression system or the specific effector molecule used in the Existing Cancer Programs as of the Effective Date (but
excluding intellectual property directed to any other specific effector molecules) (“Required Third Party IP”). Other than with respect to Required 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 ZIOPHARM Products (“Blocking Third Party IP”). Required Third Party IP and
Blocking Third Party IP are collectively referred to as “Third Party IP”). 
 (b) In the event that
either Party desires to license from a Third Party any Required Third Party IP or Blocking Third Party IP, such Party shall so notify the other Party in writing, and the IPC shall discuss such Third Party IP and its applicability to the ZIOPHARM
Products and to the Field. As provided above in Section 3.7(a), [*****] shall have the sole right and responsibility to pursue a license under Required Third Party IP, and [*****] hereby covenants that it shall not itself directly license such
Required 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 Required Third Party IP brings an infringement action against
[*****] or its Affiliates and, after written notice to [*****] of such action, [*****] fails to obtain a license to such Required Third Party IP within ninety (90) days after such notice. Following the IPC’s discussion of any Blocking
Third Party IP, subject to Section 3.7(c), [*****] shall have the right to pursue a license under Blocking Third Party IP [*****]. For the avoidance of doubt, [*****] may at any time obtain a license under Blocking 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 Blocking Third Party IP and the final version of the definitive
license agreement for any Blocking 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 Required Third Party IP, [*****]
shall provide the final version of the definitive license agreement for such Required Third Party IP to the IPC. If [*****] acquires rights under any Third Party 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. Any Party that is pursuing a license to any Third Party IP with respect to the Field under this Section 3.7 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 Required Third Party IP shall be borne solely by [*****] and shall not be included as an
Allowable Expense, and (ii) any costs incurred by [*****] in obtaining and maintaining licenses to Blocking Third Party IP (and, to the limited extent provided in subsection (b), Required Third Party IP) shall be treated as [*****]. 

(d) For any Third Party license under which ZIOPHARM 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 ZIOPHARM Products, ZIOPHARM shall use commercially reasonable efforts to ensure that ZIOPHARM 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 ZIOPHARM 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 3.7(c), provided that Intrexon shall either provide unredacted copies of such upstream license agreements to ZIOPHARM or shall disclose in writing to ZIOPHARM all of such terms and conditions that are applicable
to ZIOPHARM. ZIOPHARM 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 ZIOPHARM as provided in the preceding sentence. 

3.8 Licenses to Intrexon. Subject to the terms and conditions of this Agreement, ZIOPHARM hereby grants to Intrexon a
non-exclusive, worldwide, fully-paid, royalty-free license, under any applicable Patents or other intellectual property Controlled by ZIOPHARM 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 of Intrexon’s subcontractors. 
 3.9 Restrictions Relating to Intrexon Materials. ZIOPHARM shall use the Intrexon Materials solely for purposes of the Cancer 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, ZIOPHARM shall not, and shall ensure that ZIOPHARM personnel do not (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.

list Patents in any regulatory filing for a ZIOPHARM Product (for example, as required by 21 C.F.R. § 314.53(b)), or add or delete a Patent from a regulatory filing shall be determined by
Intrexon, after consultation with ZIOPHARM, except with respect to Product Specific Program Patents, which will be mutually determined by the Parties. 
 4.5 Diligence. 
 (a) ZIOPHARM shall use Diligent Efforts to develop
and commercialize ZIOPHARM Products. 
 (b) Without limiting the generality of the foregoing, Intrexon may, from time to
time, notify ZIOPHARM that it believes it has identified a Superior Therapy, and in such case shall provide to ZIOPHARM its then-available information about such therapy. ZIOPHARM shall have the following obligations with respect to such proposed
Superior Therapy: (i) within sixty (60) days after such notification, ZIOPHARM shall prepare and deliver to the JSC for review and approval a development plan detailing how ZIOPHARM will pursue the Superior Therapy (including a proposed
budget); (ii) ZIOPHARM shall revise the development plan as directed by the JSC; and (iii) following approval of the development plan by the JSC, ZIOPHARM shall use Diligent Efforts to pursue the development of the Superior Therapy under
the Cancer Program in accordance with such development plan. If ZIOPHARM fails to comply with the foregoing obligations, or if ZIOPHARM 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(b) (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 ZIOPHARM’s Affiliates and any permitted sublicensees shall be attributed to ZIOPHARM for the purposes of evaluating ZIOPHARM’s fulfillment of the obligations set

manufacturing of such Intrexon Materials, bulk drug product or bulk qualities of other components of ZIOPHARM Products, for use in the Field and is reasonably necessary to enable ZIOPHARM or such
contract manufacturer (as appropriate) for the sole purpose of manufacturing such Intrexon Materials, bulk drug product or bulk quantities of other components of ZIOPHARM Products, in each case as manufactured by Intrexon. The costs and expenses
incurred by Intrexon in carrying out such transfer shall be borne by Intrexon. Any manufacturing Information transferred hereunder to ZIOPHARM or its contract manufacturer shall not be further transferred to any Third Party or ZIOPHARM Affiliate
without the prior written consent of Intrexon; provided, however, that Intrexon shall not unreasonably withhold such consent if necessary to permit ZIOPHARM to switch manufacturers. 

4.7 Support Services. From time to time, on an ongoing basis, ZIOPHARM shall request, or Intrexon may propose, that Intrexon
perform certain support services with respect to the Cancer Program, such services including but not limited to, pre-clinical or clinical activities relating to transition of the Cancer Program to ZIOPHARM. To the extent that the Parties mutually
agree that Intrexon should perform such 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 Cancer Program, including without limitation those relating to the transport, storage,
and handling of Intrexon Materials and ZIOPHARM Products. 
 4.9 Trademarks. To the extent permitted by applicable law
and regulations, ZIOPHARM shall, and shall ensure that the packaging, promotional materials, and labeling for ZIOPHARM Products shall carry, in a conspicuous location, the applicable Intrexon Trademark(s), subject to ZIOPHARM’s reasonable
approval of the size, position, and location thereof. ZIOPHARM shall provide Intrexon with copies of any materials containing the Intrexon Trademarks prior to using or disseminating such materials, in order to obtain ZIOPHARM’s approval
thereof. ZIOPHARM’s use of the Intrexon Trademarks shall be subject to prior review and approval of the IPC. ZIOPHARM acknowledges Intrexon’s sole ownership of the Intrexon Trademarks and agrees not to take any action inconsistent with
such ownership. ZIOPHARM covenants that it shall not use any trademark confusingly similar to any Intrexon Trademarks in connection with any products (including any ZIOPHARM Product). From time to time during the Term, Intrexon shall have the right
to obtain from ZIOPHARM samples of ZIOPHARM Product sold by ZIOPHARM or its Affiliates or sublicensees for the purpose of inspecting the quality of such ZIOPHARM Products and use of the Intrexon Trademark(s). In the event that Intrexon inspects the
quality of such ZIOPHARM Products and use of the Intrexon Trademark, Intrexon shall notify the result of such inspection to ZIOPHARM in writing thereafter. ZIOPHARM shall comply with reasonable policies provided by Intrexon from time-to-time to
maintain the goodwill and value of the Intrexon Trademarks.

 ARTICLE 5 
 COMPENSATION 
 5.1 Equity. In partial consideration
for ZIOPHARM’s appointment as an exclusive channel partner and the other rights granted to ZIOPHARM hereunder, ZIOPHARM has agreed to issue to Intrexon certain shares of ZIOPHARM’s common stock, in accordance with the terms and conditions
of that certain Stock Purchase Agreement and Registration Rights Agreement, each of even date herewith (the “Equity Agreements”). Pursuant to the Equity Agreements, Intrexon has also agreed to purchase certain shares of the
Company’s common stock for cash consideration, subject to the terms and conditions therein. Provided that all closing conditions for the First Tranche Closing (as defined in the Equity Agreements) that are within the reasonable control of
Intrexon have been satisfied or waived, the issuance of the First Tranche Shares (as defined in the Equity Agreements) is a condition subsequent to the effectiveness of this Agreement. 

5.2 Profit-Share. 
 (a) No later than thirty (30) days after each calendar quarter in which there is positive Product Profit arising from the sale of ZIOPHARM Product in the Field in the Territory, ZIOPHARM shall
pay to Intrexon fifty percent (50%) of such Product Profit, on a ZIOPHARM Product-by-ZIOPHARM Product basis. In the event of negative Product Profit for a particular ZIOPHARM Product in any calendar quarter, neither ZIOPHARM nor Intrexon shall
owe any payments hereunder with respect to such ZIOPHARM Product. Any negative Product Profit that results from Excess Product Liability Costs, and Third Party Blocking IP Costs (as defined in Exhibit A) may be carried forward to future quarters and
offset against positive Product Profit in such future quarters for the same ZIOPHARM Product. Except as set forth in the preceding sentence, ZIOPHARM shall not be permitted to carry forward any negative Product Profits to subsequent quarters.

 (b) No later than thirty (30) days after each calendar quarter in which ZIOPHARM or any ZIOPHARM Affiliate
receives Sublicensing Revenue, ZIOPHARM shall pay to Intrexon fifty percent (50%) of such Sublicensing Revenue. As set forth in Section 3.2, sublicensing shall require Intrexon’s prior written consent. Nevertheless, this
Section 5.2(b) shall apply to Sublicensing Revenue received by ZIOPHARM or any ZIOPHARM Affiliate, even if rights were granted to the applicable sublicensee in violation of this Agreement. For purposes of clarity, sales of ZIOPHARM Products by
approved sublicensees shall not constitute Net Sales. 
 5.3 Method of Payment. All payments due to Intrexon under this
Agreement shall be paid in United States dollars by wire transfer to a bank in the United States designated in writing by Intrexon. All references to “dollars” or “$” herein shall refer to United States dollars. 

5.4 Payment Reports and Records Retention. Within thirty (30) days after the end of each calendar quarter during which Net
Sales have been generated or Allowable Expenses been incurred, ZIOPHARM shall deliver to Intrexon a written report that shall contain at a minimum for the applicable calendar quarter:

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

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

(c) itemized calculation of Allowable Expenses and Sublicensing Revenue; 

(d) the amount of the payment (if any) due pursuant to Section 5.2(a) and/or 5.2(b); 

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

(f) the exchange rates used in any of the foregoing calculations. 
 For three (3) years after each sale of ZIOPHARM Product or the incurring of an item included in Allowable Expenses, ZIOPHARM shall keep (and shall ensure that its Affiliates and, if applicable,
(sub)licensees shall keep) complete and accurate records of such sales or Allowable Expenses (as the case may be) in sufficient detail to confirm the accuracy of the payment calculations hereunder. 

5.5 Audits. 
 (a) Upon the written request of Intrexon, ZIOPHARM shall permit an independent certified public accounting firm of internationally recognized standing selected by Intrexon, and reasonably
acceptable to ZIOPHARM, 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 ZIOPHARM and its Affiliates to verify the accuracy and timeliness of
the reports and payments made by ZIOPHARM 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,
ZIOPHARM shall pay additional amounts, with interest from the date originally due as set forth in Section 5.7, 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 ZIOPHARM 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); provided, however, that such credit cannot be applied to reduce the amounts payable by ZIOPHARM to
Intrexon for any particular calendar quarter by more than twenty-five percent (25%) of the amount otherwise due to Intrexon.

 (c) Intrexon shall (i) treat all information that it receives under this
Section 5.5 in accordance with the confidentiality provisions of Article 7 and (ii) cause its accounting firm to enter into an acceptable confidentiality agreement with ZIOPHARM 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. 
 5.6 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. ZIOPHARM 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 ZIOPHARM or the appropriate governmental authority (with the assistance of ZIOPHARM 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 ZIOPHARM of its obligation to withhold tax, and ZIOPHARM shall apply the reduced rate of withholding tax, or dispense with withholding tax, as the case may be,
provided that ZIOPHARM 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, ZIOPHARM 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. 
 5.7 Late Payments. Any amount owed by ZIOPHARM 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.

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) ZIOPHARM 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 Cancer 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
related to Intrexon Channel Technology, together with all Patent rights and other intellectual property rights therein (the “Channel-Related Program IP”). ZIOPHARM hereby assigns all of its right, title and interest in and to the
Channel-Related Program IP to Intrexon. ZIOPHARM 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 ZIOPHARM 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. ZIOPHARM shall be under
appropriate written agreements with each of its employees or agents working on the Cancer Program, pursuant to which such person shall grant all rights in the Inventions to ZIOPHARM (so that ZIOPHARM may convey certain of such rights to Intrexon, as
provided herein). 
 6.2 Patent Prosecution. 
 (a) Intrexon shall have the sole right, but not the obligation, to conduct and control the filing, prosecution and maintenance of the Intrexon Patents. At the reasonable request of Intrexon,
ZIOPHARM shall cooperate with Intrexon in connection with such filing, prosecution, and maintenance, at Intrexon’s expense. Under no circumstances shall ZIOPHARM (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 use, attempt to use, or assist anyone else in using or attempting to
use, the Intrexon Know-How, Intrexon Materials, or any Confidential Information of Intrexon to support the filing of a Patent application, either in the United States or elsewhere, that contains claims directed to the Intrexon IP, Intrexon
Materials, or the Intrexon Channel Technology. 
 (b) ZIOPHARM 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 ZIOPHARM or its Affiliates and not assigned to Intrexon under Section 6.1(c) ( “ZIOPHARM Program Patents”). At the
reasonable request of ZIOPHARM, Intrexon shall cooperate with ZIOPHARM in connection with such filing, prosecution, and maintenance, at ZIOPHARM’s expense.

 (c) The Prosecuting Party shall be entitled to use patent counsel selected by it
and reasonably acceptable to the non-Prosecuting Party (including in-house patent counsel as well as outside patent counsel) for the prosecution of the Intrexon Patents and ZIOPHARM 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 ZIOPHARM Program Patents, as applicable. 
 As used above “Prosecuting Party” means Intrexon in the case of Intrexon Patents and ZIOPHARM in the case of ZIOPHARM Program Patents. 

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 a Intrexon Patent is invalid or unenforceable) (collectively, “Infringement”), either by settlement or lawsuit or other appropriate action. 

(b) Notwithstanding the foregoing, ZIOPHARM 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 ZIOPHARM 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 reasonable 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) [*****]. Intrexon and ZIOPHARM 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 ZIOPHARM 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) ZIOPHARM 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 ZIOPHARM in the Field or adversely affects any Intrexon Patent with respect to the Field without
ZIOPHARM’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 ZIOPHARM pursuant to Section 6.3(b), ZIOPHARM shall retain one hundred percent (100%) of any Recovery, but such Recovery shall be shared with Intrexon as Sublicensing Revenue. In any action initiated by Intrexon or
ZIOPHARM 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) ZIOPHARM shall promptly notify Intrexon in writing of any alleged, threatened, or actual Infringement of which it becomes aware, and Intrexon shall promptly notify ZIOPHARM in writing of any
alleged, threatened, or actual Field Infringement of which it becomes aware.

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 comments.

Intrexon shall not have any obligation to indemnify the ZIOPHARM Indemnitees to the extent that a Claim arises from (i) the gross negligence or willful misconduct of ZIOPHARM or any of its Affiliates, licensees, or sublicensees, or their
respective employees or agents; or (ii) a breach by ZIOPHARM of a representation, warranty, or covenant of this Agreement. 

9.2 Indemnification by ZIOPHARM. ZIOPHARM agrees to indemnify, hold harmless, and defend Intrexon, its Affiliates and Third
Security, and their respective directors, officers, employees, and agents (and any Third Parties which have licensed to Intrexon intellectual property rights within Intrexon IP on or prior to the Effective Date, to the extent required by the
relevant upstream license agreement) (collectively, the “Intrexon Indemnitees”) from and against any Losses resulting from Claims, to the extent arising from any of the following: (a) the gross negligence or willful misconduct

the Field, to the extent that such Losses exceed the amount (if any) covered by the applicable Party’s product liability insurance (“Excess Product Liability Costs”), shall
be paid by [*****] and shared by the Parties as Allowable Expenses for purposes of calculating Cumulative Product Profit, except to the extent such Losses arise out of any Third-Party Claim based on the gross negligence or willful misconduct of a
Party, its Affiliates, its or its Affiliates’ Sublicensees, or any of the respective officers, directors, employees and agents of each of the foregoing entities, in the performance of obligations or exercise of rights under this Agreement.

 9.4 Control of Defense. As a condition precedent to any indemnification obligations hereunder, any entity entitled to
indemnification under this Article 9 shall give written notice to the indemnifying Party of any Claims that may be subject to indemnification, promptly after learning of such Claim. If such Claim falls within the scope of the indemnification
obligations of this Article 9, then the indemnifying Party shall assume the defense of such Claim with counsel reasonably satisfactory to the indemnified Party. The indemnified Party shall cooperate with the indemnifying Party in such defense. The
indemnified Party may, at its option and expense, be represented by counsel of its choice in any action or proceeding with respect to such Claim. The indemnifying Party shall not be liable for any litigation costs or expenses incurred by the
indemnified Party without the indemnifying Party’s written consent, such consent not to be unreasonably withheld. The indemnifying Party shall not settle any such Claim if such settlement (a) does not fully and unconditionally release the
indemnified Party from all liability relating thereto or (b) adversely impacts the exercise of the rights granted to the indemnified Party under this Agreement, unless the indemnified Party otherwise agrees in writing. 

9.5 Insurance. During the term of this Agreement, ZIOPHARM shall maintain in effect and good standing a product liability
insurance policy issued by a reputable insurance company in amounts considered standard for the industry. At Intrexon’s reasonable request, ZIOPHARM shall provide Intrexon with all details regarding such policy, including without limitation

 Such right to continue development and commercialization shall be subject to ZIOPHARM’s full
compliance with the payment provisions in Article 5 and all other provisions of this Agreement that survive termination. 

(b) Termination of Licenses. Except as necessary for ZIOPHARM to continue to develop and commercialize the Retained Products as
permitted by Section 10.4(a), all rights and licenses granted by Intrexon to ZIOPHARM under this Agreement shall terminate and shall revert to Intrexon without further action by either Intrexon or ZIOPHARM. ZIOPHARM’s license with respect
to Retained Products shall be exclusive or non-exclusive, as the case may be, on the same terms as set forth in Section 3.1. 
 (c) Reverted Products. All ZIOPHARM Products other than the Retained Products shall be referred to herein as the “Reverted Products.” ZIOPHARM shall immediately cease, and shall
cause its Affiliates and, if applicable, (sub)licensees to immediately cease, all development and commercialization of the Reverted Products, and ZIOPHARM shall not use or practice, nor shall it cause or permit any of its Affiliates or, if
applicable, (sub)licensees to use or practice, directly or indirectly, any Intrexon IP with respect to the Reverted Products. ZIOPHARM shall immediately discontinue making any representation regarding its status as a licensee or channel partner of
Intrexon with respect to the Reverted Products.

 (e) Licenses to Intrexon. ZIOPHARM is automatically deemed to grant to Intrexon a worldwide, fully paid,
royalty-free, exclusive (even as to ZIOPHARM and its Affiliates), irrevocable, license (with full rights to sublicense) under the ZIOPHARM Termination IP, to make, have made, import, use, offer for sale and sell Reverted Products and to use the
Intrexon Channel Technology, the Intrexon Materials, and/or the Intrexon IP in the Field, subject to any exclusive rights held by ZIOPHARM in Reverted Products pursuant to Section 10.4(c). ZIOPHARM shall also take such actions and execute such
other instruments and documents as may be necessary to document such license to Intrexon. 
 (f) Regulatory Filings.
ZIOPHARM shall promptly assign to Intrexon, and will provide full copies of, all regulatory approvals and regulatory filings that relate specifically and solely to Reverted Products. ZIOPHARM shall also take such actions and execute such other
instruments, assignments and documents as may be necessary to effect the transfer of rights thereunder to Intrexon. To the extent that there exist any regulatory approvals and regulatory filings that relate both to Reverted Products and other
products, ZIOPHARM shall provide copies of the portions of such regulatory filings that relate to Reverted Products and shall reasonably cooperate to assist Intrexon in obtaining the benefits of such regulatory approvals with respect to the Reverted
Products.

 (g) Data Disclosure. ZIOPHARM shall provide to Intrexon copies of the relevant
portions of all material reports and data, including clinical and non-clinical data and reports, obtained or generated by or on behalf of ZIOPHARM or its Affiliates to the extent that they relate to Reverted Products, within sixty (60) days of
such termination unless otherwise agreed, and Intrexon shall have the right to use any such Information in developing and commercializing Reverted Products and to license any Third Parties to do so. 

(h) Third-Party Licenses. At Intrexon’s request, ZIOPHARM shall promptly provide to Intrexon copies of all Third-Party
agreements under which ZIOPHARM or its Affiliates obtained a license under Patents claiming inventions or know-how specific to or used or incorporated into the development, manufacture and/or commercialization of the Reverted Products. At
Intrexon’s request, ZIOPHARM shall promptly: (x) with respect to such Third Party licenses relating solely to the applicable Reverted Products, immediately assign (or cause to be assigned), such agreements to Intrexon, and (y) with
respect to all other Third Party licenses, at ZIOPHARM’s option either assign the agreement or grant (or cause to be granted) to Intrexon a sublicense thereunder of a scope equivalent to that described in Section 10.4(e), provided ZIOPHARM
has the ability to assign such agreement to Intrexon or grant a sublicense to Intrexon thereunder. In any case, thereafter Intrexon shall be fully responsible for all obligations due for its actions under the Third Party agreements. Notwithstanding
the above, if Intrexon does not wish to assume any financial or other obligations associated with a particular assignment or sublicense, then Intrexon shall so notify ZIOPHARM and ZIOPHARM shall not make such assignment or grant such sublicense (or
cause it to be made or granted). 
 (i) Remaining Materials. At the request of Intrexon, ZIOPHARM shall transfer to
Intrexon, all quantities of Reverted Product (including API or work-in-process) in the possession of ZIOPHARM or its Affiliates. ZIOPHARM shall transfer to Intrexon all such quantities of Reverted Products without charge, except that Intrexon shall
pay the reasonable costs of shipping. 
 (j) Third Party Vendors. At Intrexon’s request, ZIOPHARM shall promptly
provide to Intrexon copies of all agreements between ZIOPHARM or its Affiliates and Third Party suppliers, vendors, or distributors that relate to the supply, sale, or distribution of Reverted Products in the Territory. At Intrexon’s request,
ZIOPHARM shall promptly: (x) with respect to such Third Party agreements relating solely to the applicable Reverted Products, immediately assign (or cause to be assigned), such agreements to Intrexon, and (y) with respect to all other such
Third Party agreements, ZIOPHARM shall reasonably cooperate to assist Intrexon in obtaining the benefits of such agreements. ZIOPHARM shall be liable for any costs associated with assigning a Third Party agreement to Intrexon or otherwise obtaining
the benefits of such agreement for Intrexon, to the extent such costs are directly related to ZIOPHARM’s breach. For the avoidance of doubt, Intrexon shall have no obligation to assume any of ZIOPHARM’s obligations under any Third Party
agreement. 
 (k) Commercialization. Intrexon shall have the right to develop and commercialize the Reverted Products
itself or with one or more Third Parties, and shall have the right, without obligation to ZIOPHARM, to take any such actions in connection with such activities as Intrexon (or its designee), at its discretion, deems appropriate.

 (l) Confidential Information. Each Party shall promptly return, or at the other
Party’s request destroy, any Confidential Information of the other Party in such Party’s possession or control at the time of termination; provided, however, that each Party shall be permitted to retain (i) a single copy of each item
of Confidential Information of the other Party in its confidential legal files for the sole purpose of monitoring and enforcing its compliance with Article 7, (ii) Confidential Information of the other Party that is maintained as archive copies

Section 10.4(l). 
 10.5 Surviving Obligations. Termination or expiration of this Agreement shall not affect any
rights of either Party arising out of any event or occurrence prior to termination, including, without limitation, any obligation of ZIOPHARM to pay any amount which became due and payable under the terms and conditions of this Agreement prior to
expiration or such termination. The following portions of this Agreement shall survive termination or expiration of this Agreement: Sections 5.5, 5.7, 6.1, 6.2 (with subsection (c) surviving only to the extent relating to Intrexon Patents that
are relevant to Retained Products that, to Intrexon’s knowledge, are being developed or commercialized at such time, if any), 10.4, and 10.5; Articles 7, 9, 11, and 12; and any relevant definitions in Article 1. 

ARTICLE 11 

DISPUTE RESOLUTION 
 11.1 Disputes. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and
without resort to litigation. In the event of any disputes, controversies or differences which may arise between the Parties out of or in relation to or in connection with this Agreement (other than disputes arising from a Committee), including,
without limitation, any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement, then upon the request of either Party by written notice, the Parties agree to meet and
discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting between the Executive Officers of each Party. If the matter is not resolved within thirty (30) days following the written
request for discussions, either Party may then invoke the provisions of Section 11.2. For the avoidance of doubt, any disputes, controversies or differences arising from a Committee pursuant to Article 2 shall be resolved solely in accordance
with Section 2.4.

 11.2 Arbitration. Any dispute, controversy, difference or claim which may arise
between the Parties and not from a Committee, out of or in relation to or in connection with this Agreement (including, without limitation, arising out of or relating to the validity, construction, interpretation, enforceability, breach,
performance, application or termination of this Agreement) that is not resolved pursuant to Section 11.1 shall, subject to Section 11.10, be settled by binding “baseball arbitration” as follows. Either Party, following the end of
the thirty (30) day period referenced in Section 11.1, may refer such issue to arbitration by submitting a written notice of such request to the other Party. 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 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 3.4 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 3.4, 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, 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
