[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

of each event (each, a “Development Milestone”) described below for each Pfizer Licensed Product for each Pfizer Target (each such amount, a “Development Milestone Payment”) to be payable only once with respect to each Pfizer Licensed Product Targeting a Pfizer Target. For the avoidance of doubt, if any Development Milestone Payment is paid for an Agreement CAR-T or Pfizer Licensed Product Targeting a Pfizer Target and the Development or Commercialization of such Agreement CAR-T or Pfizer Licensed Product is terminated and such Agreement CAR-T or Pfizer Licensed Product is replaced with another Agreement CAR-T or Pfizer Licensed Product Targeting the same Pfizer Target, such Development Milestone Payment will not be owed by Pfizer if such Agreement CAR-T or Pfizer Licensed Product later achieves the same Development Milestone.


Development Milestone	Development Milestone Payments
[***]		[***	]
[***]		[***	]
[***]		[***	]
[***]		[***	]
[***]		[***	]
[***]		[***	]

If any Development Milestone described above occurs before a previous Development Milestone occurs, then any Development Milestone that has not yet been paid for achievement of any previous Development Milestone shall become due upon the achievement of the subsequent Development Milestone and payable together with the payment due upon achievement of such subsequent Development Milestone. For clarity, the achievement of a Development Milestone related to [***] will not result in the payment of any other Development Milestone related to [***].

5.3.2. Sales Milestones. Pfizer will pay to Cellectis the following one-time payments (each, a “Sales Milestone Payment”) within [***] of the last day of the Pfizer Year when aggregate Annual Net Sales of a Pfizer Licensed Product in a Pfizer Year first reach the respective threshold (a “Sales Threshold”) indicated below (each, a “Sales Milestone”); provided that such Sales Threshold with respect to a Pfizer Licensed Product must be reached within [***] following the First Commercial Sale of such Pfizer Licensed Product in the Territory.

5.4 Royalties. With respect to each Pfizer Licensed Product and subject to the provisions of Section 5.4.2, Pfizer will pay Cellectis royalties in the amount of the applicable rates (“Marginal Royalty Rates”) set forth below of Annual Net Sales of any Pfizer Licensed Product Targeting such Pfizer Target during the Royalty Term:


Annual Net Sales	Marginal Royalty Rates (% of the Annual Net Sales)
[***]		[***	]
[***]		[***	]

5.4.1. Marginal Royalty Rate Application. Each Marginal Royalty Rate set forth in the table above will apply only to that portion of the Annual Net Sales of a given Pfizer Licensed Product in the Territory during a given Pfizer Year that falls within the indicated range.

5.4.2. Royalty Adjustments. The following adjustments will be made, on a Pfizer Licensed Product-by-Pfizer Licensed Product and country-by-country basis, to the royalties payable pursuant to this Section 5.4:

(a) Generic Competition. Royalties payable following establishment of Generic Competition with respect to the sale by a Third Party of a product that is a Biosimilar Biologic Product to such Pfizer Licensed Product in such country will be payable at [***] of the otherwise applicable rate prior to application of this Section 5.4.2(a). “Generic Competition” means, with respect to a given Calendar Year with respect to a Pfizer Licensed Product in any country, that during such Calendar Year, one (1) or more Third Parties have received Regulatory Approval to sell in such country a Biosimilar Biologic Product, such Biosimilar Biologic Product(s) will be commercially available in such country and such Biosimilar Biologic Product(s) will have, in the aggregate. A product will be a “Biosimilar Biologic Product” with respect to a Pfizer Licensed Product if such product (1) has been licensed as a biosimilar or interchangeable product by FDA pursuant to Section 351(k) of the Public Health Service Act (42 U.S.C. 262(k)), as may be amended, or any subsequent or superseding law, statute or regulation, (2) has been licensed as a similar biological medicinal product by EMA pursuant to Directive 2001/83/EC, as may be amended, or any subsequent or superseding law, statute or regulation, or (3) has otherwise achieved analogous Regulatory Approval from another applicable Regulatory Authority.

(b) Third Party Patents. If, after the Effective Date, it is Necessary or Useful for Pfizer to license one or more Patent Rights from one or more Third Parties in order to Develop, Manufacture, Commercialize or use any Pfizer Licensed Product, whether directly or through any Pfizer Affiliate or Sublicensee, then Pfizer may, in its sole discretion, negotiate and obtain a license under such Patent

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

Right(s) (each such Third Party license referred to herein as an “Additional Third Party License”). Any royalty otherwise payable to Cellectis under this Agreement with respect to Net Sales of any Pfizer Licensed Product by Pfizer, its Affiliates or Sublicensees will be reduced by [***] of the amounts payable to Third Parties pursuant to any Additional Third Party Licenses, such reduction to continue until all such amounts have been expended, provided that in no event will the total royalty payable to Cellectis for any Pfizer Licensed Product be less than [***] and in no event will the royalty payable to Cellectis for any Pfizer Licensed Product be reduced below [***] (in each case, other than in the case of Cellectis’ breach of any representation, warranty or covenant hereunder). For purposes of this Section 5.4.2(b), (i) “Necessary” means that, without a license to use the Third Party’s Patent Right, the Development, Manufacture, Commercialization or use of any Pfizer Licensed Product in the form such Pfizer Licensed Product exists at the time that the Additional Third Party License is executed would, in Pfizer’s opinion, infringe such Third Party’s Patent Right and (ii) “Useful” means that Pfizer has determined in its discretion that use of such Third Party’s Patent Right would enhance the commercial potential of such Pfizer Licensed Product. For the avoidance of doubt, the Parties agree and acknowledge that this Section 5.4.2(b) will not apply with respect to royalties payable by Pfizer to any Third Party under any agreement in existence as of the Effective Date. Neither Party will intentionally negotiate with a Third Party an exclusive license that excludes sublicense rights to the other Party, in the event such Third Party rights are necessary, as determined by the negotiating Party, to Develop and Commercialize Licensed Pfizer Products and Cellectis Products in connection with the Research Program in the Field.

(c) Cellectis Third Party Agreements. Cellectis will be solely responsible for all obligations, including royalty obligations, that are due and owing or may become due and owing with respect to any Cellectis Third Party Agreements that are in effect as of the Effective Date or that Cellectis or any of its Affiliates enters into during the Term of this Agreement.

5.4.3. Fully Paid-Up, Royalty Free License. After expiration of the Royalty Term for any Pfizer Licensed Product in a country in the Territory, no further royalties will be payable in respect of sales of such Pfizer Licensed Product in such country and thereafter the License with respect to such Pfizer Licensed Product in such country will be a fully paid-up, perpetual, exclusive, irrevocable, royalty-free license.

5.5 Diagnostic and Prognostic Products. In no event will any milestone, net sales or royalty payments become due or owing pursuant to Sections 5.3 or 5.4 above with respect to any Pfizer Licensed Product Developed or Commercialized for diagnostic or prognostic purposes.

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

5.6 Reports and Payments.

5.6.1. Cumulative Royalties. The obligation to pay royalties under Section 5.4 will be imposed only once with respect to a single unit of a Pfizer Licensed Product regardless of how many Valid Claims in Patent Rights included within the Licensed Cellectis Intellectual Property would, but for this Agreement, be infringed by the use or sale of such Pfizer Licensed Product in the country in which such Pfizer Licensed Product is used or sold.

5.6.2. Royalty Statements and Payments. Within [***] after the end of each Pfizer Quarter, Pfizer will deliver to Cellectis a report setting forth for such Pfizer Quarter the following information, on a Pfizer Licensed Product-by-Pfizer Licensed Product basis: (a) the Net Sales of each Pfizer Licensed Product, (b) the basis for any adjustments to the royalty payable for the sale of each Pfizer Licensed Product and (c) the royalty due hereunder for the sale of each Pfizer Licensed Product. No such reports will be due for any Pfizer Licensed Product before the First Commercial Sale of such Pfizer Licensed Product in the Territory. The total royalty due for the sale of Pfizer Licensed Products during such Pfizer Quarter will be remitted at the time such report is delivered to Cellectis.

5.6.3. Taxes and Withholding. It is understood and agreed between the Parties that any payments made under this Agreement are exclusive of any value added or similar tax (“VAT”), which will be added thereon as applicable. Where VAT is properly added to a payment made under this Agreement, the party making the payment will pay the amount of VAT only on receipt of a valid tax invoice issued in accordance with the laws and regulations of the country in which the VAT is chargeable. In addition, in the event any of the payments made by Pfizer pursuant to this Agreement become subject to withholding taxes under the Laws of any jurisdiction, Pfizer will deduct and withhold the amount of such taxes for the account of Cellectis, to the extent required by Law, such amounts payable to Cellectis will be reduced by the amount of taxes deducted and withheld, and Pfizer will pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Cellectis an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant Governmental Authority of all amounts deducted and withheld sufficient to enable Cellectis to claim such payment of taxes. Any such withholding taxes required under applicable Law to be paid or withheld will be an expense of, and borne solely by, Cellectis. Pfizer will provide Cellectis with reasonable assistance to enable Cellectis to recover such taxes as permitted by Law.

5.6.4. Currency. All amounts payable and calculations hereunder will be in United States dollars. As applicable, Net Sales and any royalty deductions will be converted into United States dollars in accordance with Pfizer’s customary and usual conversion procedures, consistently applied.

5.6.5. Method of Payment. Except as permitted pursuant to Section 5.6.4, each payment hereunder will be made by electronic transfer in immediately available funds via either a bank wire transfer, an ACH (automated clearing house)

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

mechanism, or any other means of electronic funds transfer, at Pfizer’s election, to such bank account as the Cellectis will designate in writing to Pfizer at least forty-five (45) days before the payment is due.

5.6.6. Additional Provisions Relating to Payments. Cellectis acknowledges and agrees that nothing in this Agreement (including any schedules and exhibits hereto) will be construed as representing an estimate or projection of either (a) the number of Pfizer Licensed Products that will or may be successfully Developed or Commercialized or (b) anticipated sales or the actual value of any Pfizer Licensed Product. PFIZER MAKES NO REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, THAT IT WILL BE ABLE TO SUCCESSFULLY DEVELOP OR COMMERCIALIZE ANY PRODUCT OR, IF COMMERCIALIZED, THAT IT WILL ACHIEVE ANY PARTICULAR SALES LEVEL OF SUCH PRODUCT(S), PROVIDED THAT THE FOREGOING WILL NOT LIMIT PFIZER’S OBLIGATIONS UNDER THIS AGREEMENT.

5.7 Maintenance of Records; Audits.

5.7.1. Record Keeping. Pfizer will keep, and cause its Affiliates and Sublicensees to keep, accurate books of account and records in connection with the sale of Pfizer Licensed Products, in sufficient detail to permit accurate determination of all figures necessary for verification of royalties to be paid hereunder. Pfizer will maintain, and cause its Affiliates and Sublicensees to maintain, such records for a period of at least [***] after the end of the Calendar Year in which they were generated.

5.7.2. Audits. Upon thirty (30) days prior written notice from Cellectis, Pfizer will permit an independent certified public accounting firm of internationally recognized standing selected by Cellectis and reasonably acceptable to Pfizer to examine, at Cellectis’ sole expense, the relevant books and records of Pfizer during the period covered by such examination, as may be reasonably necessary to verify the accuracy of the reports submitted by Pfizer in accordance with Section 5.6 and the payment of royalties hereunder. An examination by Cellectis under this Section 5.7.2 will occur not more than [***] and will be limited to the pertinent books and records for any Calendar Year ending not more than [***] before the date of the request. The accounting firm will be provided access to such books and records at Pfizer’s or its Affiliates’ facilities where such books and records are kept and such examination will be conducted during Pfizer’s normal business hours. Pfizer may require the accounting firm to sign a reasonable and customary non-disclosure agreement before providing the accounting firm access to Pfizer’s facilities or records. Upon completion of the audit, the accounting firm will provide both Pfizer and Cellectis a written report disclosing whether the reports submitted by Pfizer are correct or incorrect, whether the royalties paid are correct or incorrect and, in each case, the specific details concerning any discrepancies.

If such accounting firm concludes that additional royalties were due to Cellectis, Pfizer will pay to Cellectis the additional royalties within thirty (30) days of the date Pfizer receives such accountant’s written report so concluding. If such underpayment exceeds [***] of the royalties that were to be paid to Cellectis, Pfizer also will reimburse Cellectis for all reasonable charges of such accountants for conducting the audit. If such accounting firm concludes that Pfizer overpaid royalties to Cellectis, Cellectis will repay such amount to Pfizer in full within thirty (30) days of the receipt of such accountant’s report, or, at Pfizer’s option, Pfizer will be entitled to offset all such overpayments against any outstanding or future amounts payable to Cellectis hereunder until Pfizer has received full credit for such overpayments.

5.7.4. Confidentiality. All financial information of Pfizer which is subject to review under this Section 5.7 will be deemed to be Pfizer’s Confidential Information subject to the provisions of Article 7 hereof, and Cellectis will not disclose such Confidential Information to any Third Party or use such Confidential Information for any purpose other than verifying payments to be made by Pfizer to Cellectis hereunder.

5.7.5. Costs. Cellectis shall pay the full cost of the audit unless the discrepancy is to the Cellectis’ detriment and is greater than [***] of all amounts due in such calendar year, in which cases Pfizer shall pay the reasonable cost charged by such accountant for such inspection.

5.8 No Guarantee of Success. Pfizer and Cellectis acknowledge and agree that payments to Cellectis pursuant to Section 5.2, Section 5.3 and Section 5.4: (a) have been included in this Agreement on the basis that they are only payable or otherwise relevant if a Pfizer Licensed Product is successfully Developed or Commercialized, as applicable; (b) are solely intended to allocate amounts that may be achieved upon successful Development or Commercialization of a Pfizer Licensed Product between Pfizer (who will receive all Pfizer Licensed Product sales revenues) and Cellectis; (c) are not intended to be used and will not be used as a measure of damages if this Agreement is terminated for any reason, including pursuant to Pfizer’s right to terminate at for convenience, before any such success is achieved and such amounts become due; and (d) will only be triggered, and will only be relevant as provided, in accordance with the terms and conditions of such provisions. Pfizer and Cellectis further acknowledge and agree that nothing in this Agreement will be construed as representing any estimate or projection of (i) the successful Development or Commercialization of any Pfizer Licensed Product under this Agreement, (ii) the number of Pfizer Licensed Products that will or may be successfully Developed or Commercialized under this Agreement, (iii) anticipated sales or the actual value of any Pfizer Licensed Products that may be successfully Developed or Commercialized under this Agreement or (iv) the damages, if any, that may be payable if this Agreement is terminated for any reason. Pfizer makes no representation, warranty or covenant, either express or implied, that (A) it will successfully Develop, Manufacture, Commercialize or continue to Develop, Manufacture or Commercialize any Pfizer Licensed Product in any country, (B) if Commercialized, that any Pfizer Licensed Product will achieve any particular sales level, whether in any individual country or

6.2 Patent Rights.

6.2.1. Filing, Prosecution and Maintenance of Patent Rights.

Cooperation. Without limiting any other rights and obligations of the Parties under this Agreement, the Parties will cooperate with respect to the timing, scope and filing of patent applications and patent claims relating to any Cellectis Improvements, Pfizer Improvements and Developed IP to preserve and enhance the patent protection for Agreement CAR-Ts, including the manufacture and use thereof. If the ownership rights in any Patent Rights included in Cellectis Improvements or Developed IP are substantially impeding or would substantially impede Pfizer’s prosecution of CAR-T Developed IP assigned to Pfizer pursuant to Section 6.1.1(d), or Cellectis’s prosecution of Cellectis CAR-T Developed IP assigned to Cellectis pursuant 6.1.1(e), the Parties will negotiate in good faith an amendment of the ownership of such Patent Rights included in Cellectis Improvements or Developed IP while preserving for each Party substantially the same rights, including all Milestone Payments and royalty payments, as are afforded in this Agreement.

(a) Pfizer Patent Rights. Pfizer, at its own expense, will have the sole right, but not the obligation, to prepare, file, prosecute and maintain, throughout the world, any Patent Rights that it solely owns, including Pfizer Patent Rights and Patent Rights comprised in the Pfizer Improvements and CAR-T Developed IP (to the extent assigned to Pfizer pursuant to Section 6.1.1(d)). Pfizer will keep Cellectis informed regarding the status of any Patent Right comprised in any such CAR-T Developed IP at Cellectis’ reasonable request. To the extent Pfizer wishes not to file, prosecute or maintain any such Patent Right, Pfizer will provide Cellectis with thirty (30) days prior written notice to such effect, in which event Cellectis may elect to continue filing, prosecution or maintenance of such Patent Right, and Pfizer, upon Cellectis’ written request received within such thirty (30) day period, will execute such documents and perform such acts, at Cellectis’ expense, as may be reasonably necessary to permit Cellectis to file, prosecute and maintain such Patent Right. Any such Patent Right that is prosecuted or maintained by Cellectis pursuant to this Section 6.2.1(c)(i) will continue to be owned by Pfizer, and (ii) subject to the Parties’ other rights and obligations under this Agreement, may be licensed by Pfizer to one or more Third Parties.

(b) Cellectis Patent Rights. Cellectis, at its own expense, will have the sole right, but not the obligation, to prepare, file, prosecute and maintain, throughout the world, any Patent Rights included in Licensed Intellectual Property that it solely owns or has in-licensed from Third Parties, including Cellectis Patent Rights and Patent Rights comprised in the Cellectis Improvements. Cellectis will not disclose any Pfizer Confidential Information in any Patent Rights that it files, or in connection with the prosecution of any such Patent Rights, without Pfizer’s prior written consent. Cellectis will notify Pfizer promptly upon filing or otherwise

obtaining rights in any Patent Right after the Effective Date that covers or may cover the Development, Manufacture, Commercialization or use of any Pfizer Licensed Product. In the absence of such prompt notification, any such Patent Rights will be excluded from the Valid Claim definition. Cellectis will keep Pfizer informed regarding each Patent Right included in the Licensed Intellectual Property that Cellectis or any Third Party licensor is prosecuting and will consider in good faith any recommendations made by Pfizer in regard to the filing, prosecution or maintenance of any such Patent Right. To the extent Cellectis wishes not to file, prosecute or maintain any such Patent Right (other than any such Patent Right owned or co-owned by a Third Party licensor), Cellectis will provide Pfizer with thirty (30) days prior written notice to such effect, in which event Pfizer may elect to continue filing, prosecution or maintenance of such Patent Right, and Cellectis, upon Pfizer’s written request received within such thirty (30) day period, will execute such documents and perform such acts, at Pfizer’s expense, as may be reasonably necessary to permit Pfizer to file, prosecute and maintain, at its own discretion, such Patent Right. Any such Patent Rights that are prosecuted or maintained by Pfizer pursuant to this Section 6.2.1(c) will continue to be owned by Cellectis, and will be excluded from the Valid Claim definition; and, in addition to the exclusive licenses granted to Pfizer under Section 4, Cellectis will and does hereby grant to Pfizer (subject to any existing Third Party rights) a non-exclusive, sublicensable, perpetual, irrevocable, royalty-free, fully paid-up, worldwide license to practice and exploit such Patent Rights for any and all purposes. Cellectis will not decline to pay for or participate in the filing, prosecution or maintenance of any Patent Right under any Cellectis Third Party Agreement that is included in the Licensed Intellectual Property without Pfizer’s prior written consent.

(c) Joint Patent Rights. In the event the Parties conceive or generate any Joint Developed IP, other than any Joint Developed IP that constitutes CAR-T Developed IP and is assigned to Pfizer pursuant to Section 6.1.1(c), or Cellectis CAR-T Developed IP and is assigned to Cellectis pursuant to Section 6.1.1(d), the Parties will promptly meet to discuss and determine, based on mutual consent, whether to seek patent protection thereon. Neither Party will file any Patent Right covering or claiming any such Joint Developed IP (a “Joint Patent Right”) Pfizer will have the first right to file on and control prosecution of any Patent Right covering or claiming any Joint Developed IP used in the development, manufacture, composition or use of any CAR-T Targeting such Pfizer Target in accordance with Section 6.2.1(b). For avoidance of doubt, “prosecution” as used in this Section 6.2.1 includes oppositions, nullity or revocation actions, post-grant reviews and other patent office proceedings involving the referenced Patent Rights.

(d) Liability. To the extent that a Party is obtaining, prosecuting or maintaining a Patent Right included in the Licensed Intellectual Property or Developed IP (including CAR-T Developed IP) or otherwise exercising its rights under this Section 6.2.1, such Party, and its Affiliates, employees, agents or representatives, will not be liable to the other Party in respect of any act, omission, default or neglect on the part of any such Party, or its Affiliates, employees, agents or representatives, in connection with such activities undertaken in good faith.

(e) Extensions. The decision to file for a patent term extension and particulars thereof (including which patent(s) to extend) will be made with the goal of obtaining the optimal patent term and scope of protection for Pfizer Licensed Products. Pfizer will have the sole right but not the obligation to apply for and obtain any patent term extension or related extension of rights, including supplementary protection certificates and similar rights, for any patent relating to a Pfizer Licensed Product (including the choice of which patent(s) to extend), provided that it will consult with Cellectis before applying for or obtaining any such extensions or rights for any patents included in the Licensed Cellectis Intellectual Property. The Parties will provide reasonable assistance to each other in connection with obtaining any such extensions for any patent included in the Licensed Cellectis Intellectual Property. To the extent reasonably and legally required in order to obtain any such extension in a particular country, each Party will make available to the other a copy of the necessary documentation to enable such other Party to use the same for the purpose of obtaining the extension in such country.

(f) Joint Research Agreement. This Agreement will be understood to be a joint research agreement under 35 U.S.C. § 103(c)(3) entered into for the purpose of researching, identifying and Developing Agreement CAR-Ts and Pfizer Licensed Products.

(g) Recording. If a Party deems it necessary or desirable to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate government authorities in one or more jurisdictions in the Territory, then the Parties will agree on a proposed evidence of such recording and the Parties will comply with the terms of Section 7.2.3 in respect of such filing. Each Party will execute and deliver to the other Party any documents necessary or desirable to complete such registration or recordation in accordance with the terms of Section 7.2.3.

6.2.2. Enforcement of Patent Rights.

(a) Notice. If either Pfizer or Cellectis becomes aware of any infringement that may affect competition of either Party within the Field, anywhere in the world, of any issued Patent Right within the Licensed Intellectual Property or Developed IP, such Party will promptly notify the other Party in writing to that effect.

(b) Infringement of Certain Patent Rights.

(i) Subject to the terms and conditions of any applicable Cellectis Third Party Agreements, if any infringement of a Patent Right included in the Licensed Intellectual Property by a Third Party arises from the Development, Manufacture or

Commercialization of a product that does, or may, compete with a Pfizer Licensed Product Targeting such Pfizer Target, Pfizer will have the first right, but not the obligation, to take action to obtain a discontinuance of infringement or bring suit against a Third Party infringer of such Patent Right within six (6) months from the date of notice and to join Cellectis as a party plaintiff in each of the following circumstances: (x) where the Pfizer Licensed Product with which the Third Party’s infringement will compete has been [***] or is the subject of [***] and no Cellectis Product or CAR-T product of another Cellectis licensee has begun or completed [***], or (y) where such Patent Right is directed exclusively to a Pfizer Target or a Pfizer Licensed Product Targeting such Pfizer Target; in all other circumstances, Pfizer may, with prior written consent of Cellectis (not to be unreasonably withheld), have the right to take action against such Third Party infringer.

(ii) Pfizer will bear all the expenses of any suit brought by it claiming infringement of any such Patent Right. Cellectis will cooperate with Pfizer in any such suit and will have the right to consult with Pfizer and to participate in and be represented by independent counsel in such litigation at its own expense. Pfizer will incur no liability to Cellectis as a consequence of such litigation or any unfavorable decision resulting therefrom, including any decision holding any such Patent Right invalid or unenforceable, and Pfizer will not, without Cellectis’ prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Cellectis or admits the invalidity or unenforceability of any such Patent Right.

(iii) If Pfizer has not obtained a discontinuance of infringement by, or filed suit against, any such Third Party infringer within the six (6) month period set forth in subsection (i) above, then Cellectis will have the right, but not the obligation, to bring suit against such Third Party infringer, at Cellectis’ sole expense; provided, however, that Cellectis will only have the foregoing right if Pfizer would not be required (by Applicable Law or otherwise) to join such suit as a party and such suit would not involve a Patent Right covering a then-existing Agreement CAR-T or Pfizer Licensed Product. Pfizer will have no obligation to cooperate with Cellectis in any such litigation, provided that Pfizer may, at its sole discretion, elect to consult with Cellectis and to participate in and be represented by independent counsel in such litigation at its own expense. Cellectis will incur no liability to Pfizer as a consequence of such litigation or any unfavorable decision resulting therefrom, including any decision holding any such Cellectis Patent Right or Joint Patent Right invalid or unenforceable; and Cellectis will not,

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

without Pfizer’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Pfizer or admits the invalidity or unenforceability of any such Patent Right.

The enforcing Party will keep the other Party reasonably informed of all material developments in connection with any such suit. Subject to the terms and conditions of any applicable Cellectis Third Party Agreements, any recoveries obtained by either Party as a result of any proceeding against such a Third Party infringer will be allocated as follows:

(A) Such recovery will first be used to reimburse each Party for all out-of-pocket litigation costs in connection with such litigation paid by that Party; and

(B) With respect to any remaining portion of such recovery, if Pfizer was the enforcing Party, Cellectis will receive an amount equal to the royalty that would be payable, pursuant to Section 5.4, on an amount of Net Sales of the relevant Pfizer Licensed Product(s) in the country(ies) where such infringement occurred equal to such remaining portion of such recovery, and Pfizer will receive any remaining portion of such recovery; or

(C) With respect to any remaining portion of such recovery, if Cellectis was the enforcing Party, Cellectis will receive any remaining portion of such recovery, except to the extent such recovery was calculated based on lost sales of Pfizer, in which case the allocation of such remaining portion will be made as provided in Section 6.2.2(b)(iv)(B).

(c) Other Infringement of Joint Patent Rights. With respect to any notice of a Third Party infringer of any Joint Patent Right other than in the case of a Joint Patent Right subject to Section 6.2.2(b), the Parties will meet as soon as reasonably practicable to discuss such infringement and determine an appropriate course of action and the Parties’ respective rights and responsibilities with respect to any enforcement thereof.

6.2.3. Biosimilar Notices.

(a) Upon Pfizer’s request any time after completion of the first Phase II Clinical Trial for any Pfizer Licensed Product, Cellectis will use reasonable efforts to assist and cooperate with Pfizer in establishing a strategy for responding to requests for information from Regulatory Authorities and Third Party requestors and preparing submissions responsive to any Biosimilar Notices received by Pfizer; provided that Pfizer will make the final decisions with respect to such strategy and any such responses.

(b) Biosimilar Notices. Pfizer will comply with the applicable provisions of 42 U.S.C. § 262(1) (or any amendment or successor statute thereto), any similar statutory or regulatory requirement enacted in the future regarding biologic products in the United States, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction, in each case, with respect to any Biosimilar Notice received by Pfizer from any Third Party regarding any Pfizer Licensed Product that is being Commercialized in the applicable jurisdiction, and the exchange of information between any Third Party and Pfizer pursuant to such requirements; provided that, prior to any submission of information by Pfizer to a Third Party, Cellectis will have the right to review the patent information included in such proposed submission, solely with respect to Patent Rights Controlled by Cellectis, and to make suggestions as to any changes to such patent information that Cellectis reasonably believes to be necessary; provided further that Pfizer will determine the final content of any such submission. In the case of a Pfizer Licensed Product approved in the United States under the PHS Act (or, in the case of a country in the Territory other than the United States, any similar law), to the extent permitted by Applicable Law, Pfizer, as the sponsor of the application for the Pfizer Licensed Product, will be the “reference product sponsor” under the PHS Act. Pfizer will give written notice to Cellectis of receipt of a Biosimilar Notice received by Pfizer with respect to a Pfizer Licensed Product, and Pfizer will consult with Cellectis with respect to the selection of the Patent Rights to be submitted pursuant to 42 U.S.C. § 262(1) (or any similar law in any country of the Territory outside the United States); provided that Pfizer will have final say on such selection of Patent Rights. Cellectis agrees to be bound by the confidentiality provisions of 42 U.S.C. § 262(1)(1)(B)(iii). In order to establish standing in connection with any action brought by Pfizer under this Section 6.2.3, Cellectis, upon Pfizer’s request, will reasonably cooperate with Pfizer in any such action, including timely commencing or joining in any action brought by Pfizer under this Section 6.2.3 solely to the extent any Patent Rights Controlled by Cellectis are involved in any such action, and the Parties rights and responsibilities regarding any action will be determined in accordance with Section 6.2.2(b).

6.3 Interference, Opposition, Revocation and Declaratory Judgment Actions. If the Parties mutually determine that, based upon the review of a Third Party’s patent or patent application or other intellectual property rights, it may be desirable in connection with any Agreement CAR-T or Pfizer Licensed Product to provoke or institute an interference, opposition, revocation, post-grant review or other patent office proceedings or declaratory judgment action with respect thereto, then the Parties will consult with one another and will [***] in connection with such an action. Unless otherwise mutually determined by the Parties, if (i) such impasse exists during the Research Term then Cellectis will control such action and will select counsel for such action and (ii) such impasse exists following the Research Term then Pfizer will control such action and will select counsel for such action. The rights and obligations of the Parties under Section 6.4 are expressly subject to this Section 6.3.

6.4 Infringement of Third Party Patent Rights. If the Development, Manufacture or Commercialization of any Pfizer Licensed Product is alleged by a Third Party to infringe a Third Party’s patent or other intellectual property rights, the Party becoming aware of such allegation will promptly notify the other Party. The Party that is alleged to infringe the Third Party’s patent or intellectual property rights will have the right to take such action as it deems appropriate in response to such allegation, and will be solely responsible for all damages, costs and expenses in connection therewith, subject to Section 10.1.

7.	CONFIDENTIALITY

(vi) to the extent necessary in order to enforce its rights under this Agreement and as permitted in the Agreement.

(b) In the event a Party deems it reasonably necessary to disclose Confidential Information belonging to the other Party pursuant to Section 7.2.2(a)(i)(B), the Disclosing Party will to the extent possible give reasonable advance written notice of such disclosure to the other Party and take all reasonable measures to ensure confidential treatment of such information.

7.2.3. SEC Filings and Other Disclosures. Notwithstanding any provision of this Agreement to the contrary, either Party may disclose the terms of this Agreement to the extent required, in the reasonable opinion of such Party’s legal counsel, to comply with applicable Law, including the rules and regulations promulgated by the United States Securities and Exchange Commission or any equivalent governmental agency in any country in the Territory. Notwithstanding

the foregoing, before disclosing this Agreement or any of the terms hereof pursuant to this Section 7.2.3, the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure. Further, if a Party discloses this Agreement or any of the terms hereof in accordance with this Section 7.2.3, such Party will, at its own expense, seek such confidential treatment of confidential portions of this Agreement and such other terms, as may be reasonably requested by the other Party.

7.3 Public Announcements; Publications.

7.3.1. Announcements. Except as may be expressly permitted under Section 7.2.3, neither Party will make any public announcement regarding this Agreement without the prior written approval of the other Party. For the sake of clarity, nothing in this Agreement will prevent (a) either Party from making any public disclosure relating to this Agreement if the contents of such public disclosure have previously been made public other than through a breach of this Agreement by the issuing Party or its Affiliates; (b) Pfizer from making any scientific publication or public announcement with respect to any Pfizer Licensed Product Targeting such Pfizer Target under this Agreement; provided, however, that, except as permitted under Section 7.2, Pfizer will not disclose any of Cellectis’ Confidential Information in any such publication or announcement without obtaining Cellectis’ prior written consent to do so and (c) Cellectis from making any scientific publication or public announcement with respect to any Cellectis Licensed Product Targeting such Cellectis Program Target under this Agreement; provided, however, that, except as permitted under Section 7.2, Cellectis will not disclose any of Pfizer’s Confidential Information in any such publication or announcement without obtaining Pfizer’s prior written consent to do so. The Parties agree that they will release the announcement attached hereto as Schedule 7.3.1 regarding the signing of this Agreement following the Effective Date.

Publications. During the Term, each Party will submit to the other Party (the “Non-Disclosing Party”) for review and approval any proposed academic, scientific and medical publication or public presentation which contains the Non-Disclosing Party’s Confidential Information. In addition, each Party will submit to the other Party for its review and approval any proposed publication or public presentation relating to the Research Program. In both instances, such review and approval will be conducted for the purposes of preserving the value of the Licensed Intellectual Property, Cellectis CAR-T Developed IP and Pfizer CAR-T Developed IP and the rights granted to each Party hereunder and determining whether any portion of the proposed publication or presentation containing the Non-Disclosing Party’s Confidential Information should be modified or deleted. Written copies of such proposed publication or presentation required to be submitted hereunder will be submitted to the Non-Disclosing Party no later than thirty (30) days before submission for publication or presentation (the “Review Period”). The Non-Disclosing Party will provide its comments with respect to such publications and presentations within twenty (20) days after its receipt of such written copy, and the other Party will delete any Confidential Information of

the Non-Disclosing Party upon request. The Review Period may be extended for an additional sixty (60) days in the event the Non-Disclosing Party can, within fifteen (15) days of receipt of the written copy, demonstrate reasonable need for such extension, including for the preparation and filing of patent applications. Cellectis and Pfizer will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publication governed by this Section 7.3.2.

7.4 Obligations in Connection with Change of Control. If Cellectis is subject to a Change of Control, Cellectis will, and it will cause its Affiliates and Representatives to, ensure that no Confidential Information of Pfizer is released to (a) any Affiliate of Cellectis that becomes an Affiliate as a result of the Change of Control or (b) any Representatives of Cellectis (or of the relevant surviving entity of such Change of Control) who become Representatives as a result of the Change of Control, unless such Representatives have signed individual confidentiality agreements which include equivalent obligations to those set out in this Article 7. If any Change of Control of Cellectis occurs, Cellectis will promptly notify Pfizer, share with Pfizer the policies and procedures it plans to implement in order to protect the confidentiality of Pfizer’s Confidential Information prior to such implementation and make any adjustments to such policies and procedures that are reasonably requested by Pfizer.

Notwithstanding the foregoing, a Party will have the right to terminate this Agreement pursuant to this Section 9.4 (a) in part with respect to an individual Pfizer Target or Cellectis Program Target, as applicable, only if the other Party’s material breach giving rise to such termination right relates to such Pfizer Target or Cellectis Program Target, as applicable, or (b) in its entirety only if such material breach fundamentally frustrates the objectives or transactions contemplated by this Agreement taken as a whole or affects substantially all of the Research Program.

9.7.6. Pending Dispute Resolution.

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

9.10 Right to Termination of Research Project(s) or Research Program by Pfizer upon Change of Control of Cellectis. If a Change of Control of Cellectis is consummated during the Research Term, Pfizer will have the right to terminate any Research Project or the Research Program in its entirety, upon written notice to Cellectis within [***] after consummation of such Change of Control of Cellectis. Such termination of any Research Project or the Research Program (a) will not constitute termination of this Agreement, (b) will not affect the Parties’ rights and obligations under this Agreement other than those relating to such Research Project or the Research Program and (c) will not relieve either Party of any obligation that arose prior to such termination. Following any such termination of any Research Project or the Research Program, as applicable, Pfizer will have no further funding obligation under Article 2 or Section 5.3 with respect to such Research Project or the Research Program, as applicable, other than that which may have accrued prior to such termination. In addition, if, at any time following a Change of Control of Cellectis consummated during the Research Term, Cellectis or its successor fails to perform its obligations under the Research Program in any material respect, then, effective upon written notice to Cellectis or its successor, Pfizer will have the right to terminate any Research Project or the Research Program in its entirety pursuant to this Section 9.10, and Cellectis will promptly transfer to Pfizer, at no additional cost to Pfizer, such Cellectis Know-How and Cellectis Improvements, including related materials, as is necessary for Pfizer to complete all activities contemplated under such Research Project or the Research Program, as applicable. For the avoidance of doubt, in the event that Pfizer terminates a Research Project or the Research Program in accordance with this Section 9.10, such termination will not be deemed to be a termination for cause under Section 9.4 or a termination for convenience under Section 9.5, and the only effects of such termination are as set forth in this Section 9.10. Notwithstanding any provision of this Agreement to the contrary, nothing in this Section 9.10 will limit, or preclude Pfizer from seeking, any other remedy Pfizer may have for Cellectis’ breach of this Agreement; provided that Pfizer may not seek remedy under both this Section 9.10 and Section 9.4 with respect to the same performance failure by Cellectis or its successor.

9.11 Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Cellectis are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that Pfizer, as licensee of intellectual property under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. The Parties further agree that in the event of a rejection of this Agreement by Cellectis in any bankruptcy proceeding by or against Cellectis under the U.S. Bankruptcy Code, (i) Pfizer will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in Pfizer’s possession, will be promptly delivered to it upon Pfizer’s written request therefor, and (ii) Cellectis will not interfere with Pfizer’s rights to intellectual property and all embodiments of intellectual property, and will assist and not interfere with Pfizer in obtaining intellectual

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

property and all embodiments of intellectual property from another entity. The term “embodiments” of intellectual property includes all tangible, intangible, electronic or other embodiments of rights and licenses hereunder, including all compounds and products embodying intellectual property, Pfizer Licensed Products, filings with Regulatory Authorities and related rights, and Cellectis Technology.

LIMITATION ON LIABILITY, INDEMNIFICATION AND INSURANCE.

10.1 No Consequential Damages. Except with respect to liability arising from a breach of Article 7, from any willful misconduct or intentionally wrongful act, or to the extent such Party may be required to provide indemnification under this Article 10, in no event will either Party, its Affiliates, its Sublicensees or any of its, its Affiliates’ or its Sublicensees’ respective Representatives be liable under this Agreement for any special, indirect, incidental, consequential or punitive damages, whether in contract, warranty, tort, negligence, strict liability or otherwise, including loss of profits or revenue suffered by either Party or any of its respective Affiliates or Representatives. Without limiting the generality of the foregoing, “consequential damages” will be deemed to include, and neither Party will be liable to the other Party or any of such other Party’s Affiliates, Representatives or stockholders for, any damages based on or measured by loss of projected or speculative future sales of the Pfizer Licensed Products, any Milestone Payment due upon any unachieved event under Section 5.3, any unearned royalties under Section 5.4 or any other unearned, speculative or otherwise contingent payments provided for in this Agreement.

10.2 Indemnification by Pfizer. Pfizer will indemnify, defend and hold harmless Cellectis, its Affiliates, their sublicensees, contractors, subcontractors and distributors and each of its and their respective employees, officers, directors and agents (each, a “Cellectis Indemnified Party”) from and against any and all liability, loss, damage, expense (including reasonable attorneys’ fees and expenses) and cost (collectively, a “Liability”) that the Cellectis Indemnified Party may be required to pay to one or more Third Parties resulting from or arising out of:

[***]

10.3 Indemnification by Cellectis. Cellectis will indemnify, defend and hold harmless Pfizer, its Affiliates, Sublicensees, contractors, distributors and each of its and their respective employees, officers, directors and agents (each, a “Pfizer Indemnified Party”) from and against any and all Liabilities that the Pfizer Indemnified Party may be required to pay to one or more Third Parties resulting from or arising out of:

[***]

10.4 Procedure.

10.4.1. Notice. Each Party will notify the other Party in writing in the event it becomes aware of a claim for which indemnification may be sought hereunder. In the event that any Third Party asserts a claim or other proceeding (including any governmental investigation) with respect to any matter for which a Party (the

[***] CONFIDENTIAL MATERIAL REDACTED AND SEPARATELY FILED WITH THE COMMISSION

“Indemnified Party”) is entitled to indemnification hereunder (a “Third Party Claim”), then the Indemnified Party will promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party will relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

10.4.2. Control. Subject to Pfizer’s right to control any actions described in Section 6.2 (even where Cellectis is the Indemnifying Party), the Indemnifying Party will have the right, exercisable by notice to the Indemnified Party within ten (10) Business Days after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party; provided that (a) the Indemnifying Party has sufficient financial resources, in the reasonable judgment of the Indemnified Party, to satisfy the amount of any adverse monetary judgment that is sought, (b) the Third Party Claim seeks solely monetary damages and (c) the Indemnifying Party expressly agrees in writing that as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party will be solely obligated to satisfy and discharge the Third Party Claim in full (the conditions set forth in clauses (a), (b) and (c) above are collectively referred to as the “Litigation Conditions”). Within ten (10) Business Days after the Indemnifying Party has given notice to the Indemnified Party of its exercise of its right to defend a Third Party Claim, the Indemnified Party will give notice to the Indemnifying Party of any objection thereto based upon the Litigation Conditions. If the Indemnified Party reasonably so objects, the Indemnified Party will continue to defend the Third Party Claim, at the expense of the Indemnifying Party, until such time as such objection is withdrawn. If no such notice is given, or if any such objection is withdrawn, the Indemnifying Party will be entitled, at its sole cost and expense, to assume direction and control of such defense, with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party will cooperate, and will cause its Affiliates and agents to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. In the event that the Indemnifying Party does not satisfy the Litigation Conditions or does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within ten (10) Business Days after notice thereof, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified

Party, as the case may be, will have the right to join in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

10.4.3. Settlement. The Indemnifying Party will not, without the prior written consent of the Indemnified Party, enter into any compromise or settlement that commits the Indemnified Party to take, or to forbear to take, any action. The Indemnified Party will have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief’, but will not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages without the prior written consent of the Indemnifying Party. Each of the Indemnifying Party and the Indemnified Party will not make any admission of liability in respect of any Third Party Claim without the prior written consent of the other Party, and the Indemnified Party will use reasonable efforts to mitigate Liabilities arising from such Third Party Claim.

10.5 Insurance. Each Party will obtain and maintain, during the Term, commercial general liability insurance, including products liability insurance, with reputable and financially secure insurance carriers (or pursuant to a program of self-insurance reasonably satisfactory to the other Party) to cover its indemnification obligations under Section 10.2 or Section 10.3, as applicable, in each case with limits of not less than [***] per occurrence and in the aggregate.

11.

11.3 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 the Agreement.

11.4 Force Majeure. Each Party will be excused from the performance of its obligations under this Agreement to the extent that such performance is prevented by force majeure (defined below) and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse will be continued so long as the condition constituting force majeure continues and the nonperforming Party takes Commercially Reasonable Efforts to resume performance. For purposes of this Agreement, “force majeure” will include conditions beyond the control of the Parties, including an act of God, voluntary or involuntary compliance with any Applicable Law or order of any government, war, act of terror, civil commotion, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, or destruction of production facilities or materials by fire, earthquake, storm or like catastrophe.

11.5 Notices. Any notice or notification required or permitted to be provided pursuant to the terms and conditions of this Agreement (including any notice of force majeure, breach, termination, change of address, etc.) will be in writing and will be deemed given upon receipt if delivered personally or by facsimile transmission (receipt verified), five days after deposited in the mail if mailed by registered or certified mail (return receipt requested) postage prepaid, or on the next Business Day if sent by overnight delivery using a nationally recognized express courier service and specifying next Business Day delivery (receipt verified), to the Parties at the following addresses or facsimile numbers (or at such other address or facsimile number for a Party as will be specified by like notice, provided, however, that notices of a change of address will be effective only upon receipt thereof):

If any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same will not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement will be construed as if such clause or portion thereof had never been contained in this Agreement, and there will be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law.

11.9 Descriptive Headings. The descriptive headings of this Agreement are for convenience only and will be of no force or effect in construing or interpreting any of the provisions of this Agreement.

11.10 Dispute Resolution. If any dispute or disagreement arises between Pfizer and Cellectis in respect of this Agreement, they will follow the following procedures in an attempt to resolve the dispute or disagreement:

11.10.1. The Party claiming that such a dispute exists will give notice in writing (a “Notice of Dispute”) to the other Party of the nature of the dispute.

11.10.2. Within [***] of receipt of a Notice of Dispute, the Pfizer Alliance Manager and the Cellectis Alliance Manager will meet in person or by teleconference and exchange written summaries reflecting, in reasonable detail, the nature and extent of the dispute, and at this meeting they will use their reasonable endeavors to resolve the dispute.

11.10.3. If the Alliance Managers are unable to resolve the dispute during the meeting described in Section 11.10.2 or if for any reason such meeting does not take place within the period specified in Section 11.10.2, then the dispute will be referred to the JRC which will meet no later [***] following the initial receipt of the Notice of Dispute and use reasonable endeavors to resolve the dispute.

11.10.4. If the JRC is unable to resolve the dispute during the meeting described in Section 11.10.3 or if for any reason such meeting does not take place within the period specified in Section 11.10.3, then the head of Rinat and the Chief Executive Office of Cellectis will meet at a mutually agreed-upon time and location for the purpose of resolving such dispute.

11.10.5. If, within a further period of [***], or if in any event within [***] of initial receipt of the Notice of Dispute, the dispute has not been resolved, or if, for any reason, the meeting described in Section 11.10.4 has not been held within [***] of initial receipt of the Notice of Dispute, then the Parties agree that, subject to Section 11.11 below, either Party may initiate litigation to resolve the dispute.

11.11 Election of Resolution Process. Notwithstanding any provision of Section 11.10 to the contrary, if (i) either Party raises any allegation or claim of Misuse (each, a “Misuse Allegation”) and (ii) the Parties are unable to resolve such Misuse Allegation pursuant to the dispute escalation process described in Sections 11.10.1 through 11.10.5 (the “Escalation Process”), then, following completion of the Escalation Process, the Parties may mutually agree to have such Misuse Allegation resolved pursuant to the terms of Section 11.12 (the “Arbitration Process”). If the Parties fail to agree on use of arbitration pursuant to Section 11.12 in a timely manner (not to exceed [***]), then the Parties will be deemed to have elected to have such Misuse Allegation resolved through litigation.

11.12 Arbitration Process. If the Parties mutually elect to resolve any Misuse Allegation pursuant to the Arbitration Process, then such Misuse Allegation will be referred to and finally resolved by binding arbitration in accordance with the Commercial Rules and Procedures (the “Rules”) of the International Chamber of Commerce (“ICC”), by an arbitral tribunal composed of three arbitrators, all of whom will have relevant experience in pharmaceutical industry, appointed by agreement of the Parties in accordance with the Rules. If, at the time of the arbitration, the Parties agree in writing to submit the dispute to a single arbitrator, said single arbitrator will (1) have relevant experience in pharmaceutical industry and (2) be appointed by agreement of the Parties, or, failing such agreement, by ICC in accordance with the Rules. The foregoing

The Parties hereby agree that, subject to the provisions of this Section 11.12.3, the arbitrator(s) has authority to issue rulings and orders regarding all procedural and evidentiary matters that the arbitrator(s) deem reasonable and necessary with or without petition therefore by the Parties as well as the final ruling and judgment. Rulings will be issued by written order summarizing the arbitration proceedings no more than 30 days after the final submissions of the Parties.

11.12.6. Unauthorized Disclosure of Confidential Information to Third Parties. Notwithstanding any provision of this Agreement to the contrary (i) the provisions of this Section 11.12 will not apply to Pfizer’s disclosure of Cellectis Confidential Information to any Third Party in violation of Section 7 and (ii) Cellectis reserves its rights under Section 11.10 to immediately initiate litigation seeking any remedy at law or in equity, including the issuance of a preliminary, temporary or permanent injunction, to preserve or enforce its rights under Section 7 with respect to any such unauthorized disclosure.

11.13 Governing Law. This Agreement, and all claims arising under or in connection therewith, will be governed by and interpreted in accordance with the substantive laws of the State of New York, without regard to conflict of law principles thereof

11.15 Entire Agreement. This Agreement, including its Exhibits and Schedules, constitutes and contains the complete, final and exclusive understanding and agreement of the Parties and cancels and supersedes any and all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties respecting the subject matter hereof and thereof, including the Confidentiality Agreement which is hereby terminated effective as of the Effective Date, provided that such Confidentiality Agreement will continue to govern the treatment of Confidential Information disclosed by the Parties prior to the Effective Date in accordance with its terms.

11.16 Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing herein contained will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party

for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

11.19 No Third Party Rights or Obligations. No provision of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligation in any Person not a Party to this Agreement. However, Pfizer may decide, in its sole discretion, to use one or more of its Affiliates to perform its obligations and duties hereunder, provided that Pfizer will remain liable hereunder for the performance by any such Affiliates of any such obligations.
