ARTICLE 2

LICENSES; EXCLUSIVITY

2.1 Licenses to Pfizer.

(a) License Grants. Subject to the terms and conditions of this Agreement (including Sangamo’s retained rights), effective as of the Effective Date and in each case without limiting any other license (or sublicense) granted under this Agreement, Sangamo hereby grants, and will cause its Affiliates to hereby grant, to Pfizer:

(i) an exclusive (even as to Sangamo and its Affiliates except as provided in Section 2.1(c)), royalty-bearing license (or, to the extent any Licensed Technology is Controlled by Sangamo or its Affiliates pursuant to a Sangamo Third Party Agreement, a sublicense), with the right to sublicense solely as provided in Section 2.1(b), under the Licensed Technology, to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have Commercialized and otherwise exploit Products in the Field in the Territory; and

(ii) a fully paid and royalty-free (except to the extent that any payments are owed to any Upstream Licensor with respect to the practice of a sublicense granted pursuant to this subsection (ii)), worldwide, non-exclusive license (or sublicense, as applicable), with the right to sublicense solely as provided in Section 2.1(b), under the Licensed Companion Diagnostic Technology, to use, have used, develop, have developed, make, have made, sell, have sold, offer for sale, import, export, and otherwise exploit Companion Diagnostic Assays for (A) use in [ * ] and (B) otherwise for use in connection with the Product in the Field. Notwithstanding any provision to the contrary in this Agreement, the license granted under this Section 2.1(a)(ii) hereof shall be, as of the completion of the Research Term (unless this Agreement has been terminated as contemplated in (X) Section 5.1 because no Compounds have been identified as of such completion date or (Y) Section 1.42 because no Lead Development Compound has been identified as of such completion date), perpetual and irrevocable and shall survive expiration or any other termination of this Agreement.

(b) Sublicenses.

(i) Subject to the terms and conditions of this Agreement and the applicable Sangamo Third Party Agreements, Pfizer may grant to its Affiliates or Third Parties (through one or more tiers) sublicenses under the licenses granted by Sangamo to Pfizer under Sections 2.1(a)(i) and 2.1(a)(ii) upon written notice to Sangamo; provided that Pfizer shall remain responsible for the performance of all of its Sublicensees to the same extent as if such activities were conducted by Pfizer, and shall remain responsible for any payments due hereunder with respect to activities of any Sublicensees.

(ii) Pfizer shall provide Sangamo with a copy of each executed sublicense agreement within [ * ] after execution thereof (excluding any such agreement under which Pfizer grants a sublicense to an Affiliate or solely to conduct Development or Manufacturing on behalf of Pfizer or its Affiliate, unless Sangamo is obligated to provide such copy to a Third Party Licensor in which case Sangamo will obtain the written consent from Pfizer, not to be unreasonably withheld, prior to entering into such license which would obligate Sangamo to provide such copy), which shall be treated by Sangamo as Pfizer’s Confidential Information, provided that to the extent required by any Sangamo Third Party Agreement, Sangamo shall be permitted to provide a confidential copy to the applicable Third Party Licensor. Prior to providing a copy of such sublicense agreement to Sangamo, Pfizer may (unless otherwise required by a Sangamo Third Party Agreement and Sangamo has received Pfizer’s prior written consent) redact certain terms of any such sublicense agreement to the extent not pertinent to an understanding of a Party’s obligations or benefits under this Agreement or a verification of compliance with the requirements of this Agreement.

(c) Retained Rights for Exclusive Licenses. Notwithstanding the exclusive license granted by Sangamo to Pfizer under Section 2.1(a)(i), Sangamo retains the rights under the Licensed Technology to perform its obligations and to exercise its rights under this Agreement, whether directly or through one or more subcontractors.

(d) Sangamo Third Party Agreements. The licenses granted to Pfizer in Section 2.1(a) include sublicenses under Licensed Technology or Licensed Companion Diagnostic Technology licensed to Sangamo pursuant to the Sangamo Third Party Agreements, which sublicenses are subject to the terms of such Sangamo Third Party Agreements. The Sangamo Third Party Agreements in effect as of the Effective Date are listed on Exhibit F and the applicable terms in such Sangamo Third Party Agreements are set forth on Schedule 2.1(d), which may be amended by mutual agreement of the Parties for Sangamo Third Party Agreements entered into after the Effective Date. Pfizer acknowledges and agrees to be bound by such terms, and agrees not to take or fail to take any action that would cause Sangamo to be in breach of any Sangamo Third Party Agreement, subject to Sangamo’s compliance with Section 2.7(a). Pfizer acknowledges that certain of the licenses granted to Sangamo under the Sangamo Third Party Licenses are non-exclusive, and that Pfizer’s license pursuant to Section 2.1(a)(i) with respect to the relevant Licensed Technology are exclusive only with respect to Sangamo, and not with respect to its licensor.

2.2 Reciprocal Non-Exclusive Research License for Disclosed Know-How and Confidential Information. Subject to any pre-existing exclusive license grants to Third Parties as of the Effective Date, and excluding any license whose grant or practice would cause Sangamo to be in breach of any exclusivity obligation to any Third Party existing as of the Effective Date, and without limiting any other license granted to either Party under this Agreement:

(a) Pfizer hereby grants and shall cause its Affiliates to hereby grant to Sangamo a non-exclusive, irrevocable, perpetual, royalty-free, fully paid-up, worldwide license, with the right to sublicense to Sangamo’s Affiliates, to use for research purposes (which excludes [ * ]) all Know-How and Confidential Information of Pfizer that is (i) Controlled by Pfizer or its Affiliates and (ii) disclosed to Sangamo or its Affiliates pursuant to this Agreement during the Term; provided that nothing in this Section 2.2(a) shall give Sangamo or its Affiliates any right to practice under any Patent Right owned or Controlled by Pfizer or its Affiliates.

(b) Sangamo hereby grants and shall cause its Affiliates to hereby grant to Pfizer a non-exclusive, irrevocable, perpetual, royalty-free, fully paid-up, worldwide license, with the right to sublicense to Pfizer Affiliates, to use for research purposes (which excludes [ * ]) all Know-How and Confidential Information of Sangamo that is (i) Controlled by Sangamo or its Affiliates and (ii) disclosed to Pfizer or its Affiliates pursuant to this Agreement during the Term; provided that nothing in this Section 2.2(b) shall give Pfizer or its Affiliates any right to practice under any Patent Right owned or Controlled by Sangamo or its Affiliates.

2.3 No Implied Licenses; Negative Covenant. Except as expressly set forth herein, neither Party shall acquire any license or other intellectual property interest, by implication or otherwise, under or to any Patent Rights, Know-How, or other intellectual property owned or controlled by the other Party. Neither Party shall, nor shall permit any of its Affiliates or Sublicensees to, practice any Patent Rights or Know-How licensed to it by the other Party outside the scope of the license granted to it under this Agreement, provided that, notwithstanding anything to the contrary in this Agreement, nothing in this Agreement (including but not limited to this Section 2.3) shall be deemed to prevent or restrict in any way the ability of a Party or its Affiliates to conduct any activities in the Territory, which activities would be allowed under any safe harbor, research exemption, government or executive declaration of urgent public health need, or similar right available in law or equity if conducted by a Third Party.

2.4 Exclusivity.

(a) Exclusivity Obligations. Subject to Section 2.4(c), during the [ * ], Sangamo and Pfizer shall not, by itself or with or through any Affiliate or Third Party (including through the grant of a license to a Third Party) research, develop, manufacture or commercialize any zinc finger binding protein that specifically binds to C9ORF72 (“Competing Program”), except for the research, development, manufacture and commercialization of Products in accordance with this Agreement.

(b) Exception. Notwithstanding Section 2.4(a), if a Third Party becomes an Affiliate of a Party during the exclusivity period set forth in Section 2.4(a) through merger, acquisition, consolidation or other similar transaction and such new Affiliate, as of the effective date of such transaction, is engaged, or has a then-existing plan to engage, in the conduct of a Competing Program, then:

(i) If such transaction results in a Change of Control of such Party, then such new Affiliate shall have the right to continue such Competing Program and such continuation shall not constitute a breach by such Party of its exclusivity obligation set forth in Section 2.4(a), provided that such new Affiliate conducts such Competing Program independently of the activities under this Agreement and does not use any Licensed Technology, Licensed Companion Diagnostic Technology, or the Confidential Information of the other Party in the conduct of such Competing Program.

(ii) If such transaction does not result in a Change of Control of such Party, then such Party and its new Affiliate shall have [ * ] from the closing date of such transaction to wind down or divest such Competing Program, and its new Affiliate’s conduct of such Competing Program during such [ * ] period shall not constitute a breach by such Party of its exclusivity obligations set forth in Section 2.4(a), provided that such new Affiliate conducts such Competing Program during such [ * ] period independently of the activities under this Agreement and does not use any Licensed Technology, Licensed Companion Diagnostic Technology, or the Confidential Information of the other Party in the conduct of such Competing Program.

(c) Early Termination. If this Agreement is terminated prior to the expiration of each Party’s exclusivity obligations as set forth in Section 2.4(a), then:

(i) If this Agreement is terminated by Pfizer during the Research Term pursuant to Section 8.2(b), Pfizer’s exclusivity obligations hereunder shall terminate upon the [ * ] and Sangamo’s exclusivity obligations hereunder shall terminate upon the [ * ].

(ii) If this Agreement is terminated by Sangamo during the Research Term pursuant to Section 8.2(b), Sangamo’s exclusivity obligations hereunder shall terminate upon the [ * ] and Pfizer’s exclusivity obligations hereunder shall terminate upon the [ * ].

(iii) If this Agreement is terminated as contemplated in (A) Section 5.1 because no Compounds have been identified as of the completion of the Research Term or (B) Section 1.42 because no Lead Development Compound has been identified as of the completion of the extended Research Term, then in either case (A) or (B) each Party’s exclusivity obligations hereunder shall terminate on the [ * ], provided that in the case of (A) that, if before the [ * ] Sangamo identifies a zinc finger protein that had such zinc finger protein been identified during the Research Term it would have been a Compound, Sangamo shall provide Pfizer with prompt written notice and the Parties shall in good faith negotiate entering into an agreement under substantially similar terms as this Agreement, [ * ], to allow for Pfizer to further research, develop and commercialize such zinc finger protein or a derivative thereof isolated by Sangamo pursuant to the new agreement.

(iv) If this Agreement is terminated by Pfizer for any other reason, each Party’s exclusivity obligations hereunder shall terminate upon the [ * ].

2.5 Upstream Licenses. If, during the Term, Sangamo obtains Control of any intellectual property rights that are owned or controlled by a Third Party and that are necessary or useful for the Development, Manufacture, use, sale, offer for sale, importation or Commercialization of any Compound in the Field in the Territory, then Sangamo shall notify Pfizer in writing, including a description of such intellectual property rights, if they have been non-exclusively (“Non-Exclusive Upstream License”) or exclusively (“Exclusive Upstream

License”) licensed and, with respect to such non-exclusively licensed intellectual property rights, of any payments that would be due as a result of the grant, maintenance or exercise of a sublicense to Pfizer under such intellectual property rights and a reasonable allocation (based on the scope of the license relative to the scope of the sublicense to Pfizer and provided that Sangamo disclose all the other relevant facts used by Sangamo to determine said reasonable allocation) of any other amounts payable under such license agreement that do not result solely from activities with respect to a particular product or entity (e.g., upfront fees or annual license fees). Each Non-Exclusive Upstream License for which Pfizer agrees to reimburse Sangamo for payments thereunder pursuant to Section 2.5(a), and each Exclusive Upstream License, will be an “Upstream License”.

(a) Non-Exclusive Upstream Licenses. If within [ * ] after the receipt of such notice regarding a Non-Exclusive Upstream License, Pfizer agrees in writing to reimburse Sangamo for all payments due under such license as described above in this Section 2.5, then such intellectual property rights shall be included in the Licensed Technology and sublicensed to Pfizer under the terms and conditions of this Agreement (which sublicense shall be subject and subordinate to the terms and conditions of the Upstream License), and the agreement pursuant to which Sangamo obtained Control of such intellectual property rights shall become an Upstream License under this Agreement. If Pfizer does not agree in writing within such [ * ] to reimburse Sangamo for all such payments, then such intellectual property rights shall be deemed “Excluded Upstream IP” and shall be excluded from the Licensed Technology, and the agreement pursuant to which Sangamo obtains Control of such intellectual property rights shall not be included in the Upstream Licenses. For avoidance of doubt, should Pfizer secure a license to any Excluded Upstream IP, [ * ] would apply.

(b) Exclusive Upstream Licenses. If Sangamo obtains an Exclusive Upstream License, such exclusively licensed intellectual property rights shall be included in the Licensed Technology and sublicensed to Pfizer under the terms and conditions of this Agreement (which sublicense shall be subject and subordinate to the terms and conditions of the Upstream License), and the agreement pursuant to which Sangamo obtains Control of such intellectual property rights shall automatically become an Upstream License under this Agreement.

(c) Information. Pfizer shall (i) provide Sangamo, in a timely manner as necessary for Sangamo to comply with its obligations under each Sangamo Third Party Agreement, with all information needed in order to determine the requirement to make, and the amount of, any payment thereunder, to the extent resulting from the grant, maintenance or exercise of a sublicense to Pfizer and (ii) promptly (but in no event later than [ * ] after Sangamo’s submission of an invoice therefor) reimburse Sangamo for the full amount of each such payment under a Non-Exclusive Upstream License; provided Sangamo has provided Pfizer the information required under this Section 2.5 and any other information necessary for Pfizer to comply with any payment obligations and in the case of clause (ii), Pfizer has agreed under Section 2.5(a) to make such payments.

2.6 Direct Licenses to Affiliates. Pfizer may, from time to time, request that Sangamo grant licenses or sublicenses, to the Licensed Technology or Licensed Companion Diagnostic Technology and of the same or narrowed scope as the licenses granted to Pfizer pursuant to Section 2.1(a), directly to Affiliates of Pfizer by giving written notice, upon receipt of which Sangamo agrees to enter into and sign a separate direct license or sublicense agreement with such designated Affiliate of Pfizer. All such direct license or sublicense agreements will be consistent with the terms and conditions of this Agreement, except for such modifications as may be required by applicable Laws in the country in which the direct license or sublicense will be exercised (excluding any such modifications that would require Sangamo to grant additional rights or take on additional obligations beyond what is set forth in this Agreement without any such modifications). The Parties further agree to make any amendments to this Agreement that are necessary to conform the combined terms of such direct licenses or sublicenses and this Agreement to the terms of this Agreement as set forth on the Effective Date. In connection with any such direct license, Sangamo may require that Pfizer guarantee the performance of its Affiliate. All reasonable costs of making such direct license or sublicense agreement(s) or amending this Agreement, including Sangamo’s reasonable attorneys’ fees, under this Section 2.6 will be borne by Pfizer and reimbursed to Sangamo within [ * ] of Sangamo’s invoice therefor.

2.7 Sangamo Third Party Agreements.

(a) Maintenance of Sangamo Third Party Agreements. Sangamo will maintain in full effect and will perform all of its obligations in a timely manner under each of the Sangamo Third Party Agreements. Absent Pfizer’s prior written consent (which may be provided, conditioned or withheld in Pfizer’s sole discretion), Sangamo will not terminate, modify or amend any Sangamo Third Party Agreements in any manner that would (i) adversely affect any of the rights granted to Pfizer under this Agreement, (ii) impose any obligations upon Pfizer hereunder that are in addition to those obligations that exist under this Agreement based on the Current Licenses as they exist on the Effective Date or each Upstream License as it exists when it becomes an Upstream License pursuant to Section 2.5 or (iii) adversely affect Sangamo’s ability to perform its obligations under this Agreement. Further, Sangamo will not take any action or omit to take any action that would cause it to be in material breach of any Sangamo Third Party Agreements or that would give rise to a right of any Third Party Licensor to terminate the applicable Sangamo Third Party Agreements.

(b) Communications and Performance. Notwithstanding anything to the contrary in this Agreement, Sangamo will facilitate any communications between Pfizer and any Third Party Licensor required for Pfizer to exercise the rights granted to it pursuant to this Article 2 and will use Commercially Reasonable Efforts to cause each applicable Third Party Licensor to perform all of its obligations under the applicable Sangamo Third Party Agreement that are necessary to effectuate the rights granted to Pfizer under this Agreement.

(c) Breach of Sangamo Third Party Agreement. If Sangamo receives notification from the applicable Third Party Licensor of any actual or potential breach by Sangamo, or otherwise becomes aware of its breach, of any Sangamo Third Party Agreement, which breach if uncured could give rise to the termination of the applicable Sangamo Third Party Agreement, then Sangamo will promptly notify Pfizer of such breach, such notice to include a

copy of the notification (if any) received from such Third Party Licensor. To the extent that any act or omission on the part of Pfizer is the cause of such breach of a Sangamo Third Party Agreement, Pfizer will take all actions and provide Sangamo with all cooperation necessary to cure such breach, in each case as reasonably requested by Sangamo and at Pfizer’s sole cost and expense. To the extent that Pfizer is not the cause of such breach of a Sangamo Third Party Agreement, Sangamo will have the first opportunity to cure such breach in accordance with a plan to be mutually agreed upon by the Parties in writing, acting reasonably (each, a “Cure Plan”). If (a) Sangamo does not use diligent efforts to cure such breach pursuant to the applicable Cure Plan or (b) Sangamo is unable to cure such breach in accordance with the applicable Cure Plan or it becomes reasonably apparent that Sangamo will not be able to cure such breach pursuant to the applicable Cure Plan, in each case during the applicable cure period, then Pfizer may, at its election and in its sole discretion, act reasonably to cure such breach and Sangamo will take all actions and provide Pfizer with all cooperation to cure such breach, in each case as reasonably requested by Pfizer. Further, if Pfizer is not the cause of such breach, then Sangamo will, at Pfizer’s sole election, (i) reimburse Pfizer for all reasonable out-of-pocket costs and expenses incurred by or on behalf of Pfizer or any of its Representatives in connection with curing such breach; or (ii) permit Pfizer to offset any such reasonable out-of-pocket costs and expenses incurred by or on behalf of Pfizer or any of Pfizer’s Representatives in connection with curing such breach against Pfizer’s future payment obligations to Sangamo (or any of its successor or assigns) under this Agreement.

(d) Termination of any Sangamo Third Party Agreement. In the event that any Sangamo Third Party Agreement is terminated by the applicable Third Party Licensor and this Agreement, as of the effective date of such termination, has not otherwise been terminated in its entirety, Pfizer, to the extent permitted by such Sangamo Third Party Agreement (or if not permitted or addressed in such Sangamo Third Party Agreement, to the extent permitted by the applicable Third Party Licensor), will have the right, at Pfizer’s election, to convert the sublicenses granted under this Agreement by Sangamo to Pfizer under the Licensed Technology licensed to Sangamo pursuant to such Sangamo Third Party Agreement to a direct license from the applicable Third Party Licensor to Pfizer on the terms and conditions contained in such Sangamo Third Party Agreement (with Pfizer assuming the applicable obligations of Sangamo thereunder) or such other terms and conditions as may be negotiated by Pfizer and the applicable Third Party Licensor. In the event Pfizer enters into any such direct license with a Third Party Licensor, Sangamo will, at Pfizer’s sole election, (i) reimburse Pfizer for all reasonable out-of-pocket costs and expenses incurred by or on behalf of Pfizer or any of its Representatives in connection with entering into and exercising its rights or performing under such direct license to the extent that Sangamo would have borne such costs if the applicable Sangamo Third Party Agreement had not been terminated; or (ii) permit Pfizer to offset any such reasonable out-of-pocket costs and expenses (to the extent not reimbursed pursuant to clause (i) above) incurred by or on behalf of Pfizer or any of Pfizer’s Representatives in connection with entering into and exercising its rights or performing under such direct license to the extent that Sangamo would have borne such costs if the applicable Sangamo Third Party Agreement had not been terminated, against Pfizer’s future payment obligations to Sangamo (or any of its successor or assigns) under this Agreement.

(e) Consents and Waivers. In the event that any provision in any Sangamo Third Party Agreement which conflicts with this Agreement or adversely impacts the activities contemplated under this Agreement comes to the attention of either Sangamo or Pfizer, then either the Parties will (i) in Pfizer’s sole discretion, amend this Agreement to avoid such conflict or (ii) Sangamo, in consultation with Pfizer, will use Commercially Reasonable Efforts to obtain any and all additional required consents or waivers from the applicable Third Party Licensor(s) which may be necessary to align the conflicting provision(s) of the applicable Sangamo Third Party Agreement with this Agreement and to permit the activities contemplated by this Agreement. Notwithstanding the foregoing, Sangamo shall not have any obligation to obtain or attempt to obtain any rights to file, prosecute, maintain, enforce, defend or extend any Patent within the Licensed Technology that is non-exclusively licensed to Sangamo pursuant to a Sangamo Third Party Agreement.

2.8 Right of Reference. Sangamo hereby grants to Pfizer, its Affiliates and its Sublicensees a “Right of Reference,” as that term is defined in 21 C.F.R. § 314.3(b) (or any analogous Law recognized outside of the United States), to all regulatory filings Controlled by Sangamo or its Affiliates that relate to any Compound or Product, solely for purposes of Developing, Manufacturing and Commercializing Products in the Field in the Territory, and Sangamo will provide a signed statement to this effect, if requested by Pfizer, in accordance with 21 C.F.R. § 314.50(g)(3) (or any analogous Law outside of the United States).

2.9 Initial Data Transfer. Within a reasonable time not to exceed [ * ] following the Effective Date, Sangamo will disclose to Pfizer true, accurate and complete copies of all Licensed Know-How, in each case to the extent developed by Sangamo on or prior to the Effective Date and in such format as Pfizer may reasonably request (including by download of digital files to a secure website or e-room designated and controlled by Pfizer).

2.10 Continuing Disclosure and Knowledge Transfer. On a [ * ] basis, or more frequently at the reasonable request of Pfizer during the Term, Sangamo, to the extent not previously provided to Pfizer, will provide to Pfizer a written summary of all Licensed Technology other than Research Program Technology developed by Sangamo or that otherwise comes into the Control of Sangamo. Further, Sangamo will make appropriate personnel available to Pfizer at reasonable times and places and upon reasonable prior notice for the purpose of assisting Pfizer to understand and use the Licensed Technology in connection with Pfizer’s Development of Compounds and Products.

Sangamo will not subcontract any of its responsibilities under the Research Plan without Pfizer’s prior written consent; provided that any subcontractors expressly identified in the Research Plan to conduct specific activities thereunder shall be deemed to have received such consent from Pfizer. Sangamo shall be responsible for the management of all permitted subcontractors. The engagement by Sangamo or its Affiliate of any subcontractor in compliance with this Section 3.2(b) shall not relieve Sangamo of its obligations under this Agreement or the Research Plan. Any agreement between Sangamo or its Affiliate and a permitted subcontractor pertaining to the Research Plan activities shall be consistent with the provisions of this Agreement including (i) an obligation to assign all intellectual property rights generated during its performance of such Research Plan to Sangamo and (ii) terms and conditions under which such Third Party is obligated to preserve the confidentiality of any Confidential Information of Pfizer received by such Third Party from Sangamo that are at least as restrictive as those described in Article 7. Furthermore, unless otherwise agreed by Pfizer in writing, prior to or at the time of engagement of any subcontractor to perform any obligations hereunder, Sangamo or its Affiliate shall cause such subcontractor to agree in writing to be bound by terms providing for Pfizer rights no less favorable to Pfizer than the rights granted to Pfizer in this Agreement.

(c) Sangamo Personnel Matters. Sangamo acknowledges and agrees that it is solely responsible for the compensation of its personnel assigned to the Research Plan, and shall be responsible for withholding all national, state, local or other applicable taxes and similar items for such personnel. Sangamo also shall be responsible for all other employer related obligations with respect to such personnel, including providing appropriate insurance coverage and employee benefits, and making all other deductions required by law affecting the gross wages of each employee. Sangamo personnel assigned to the Research Plan activities are not nor shall they be deemed to be employees of Pfizer.

Net sales above [ * ] up to and including [ * ]		[ * ]%
Net sales above [ * ]		[ * ]%

Each Royalty Rate set forth in the table above will apply only to that portion of the Net Sales of a given Product in the Territory during a given Pfizer Year that falls within the indicated range. An example calculation of royalties under this Section 5.3(a) is set forth below.

By way of example only, if (i) Pfizer, its Affiliates or its Sublicensees sell two Products in the Territory during a given Pfizer Year, (ii) Net Sales of the first Product in the Territory during such Pfizer Year are $[ * ] and (iii) Net Sales of the second Product in the Territory during such Pfizer Year are $[ * ], then the royalties payable by Pfizer under this Section 5.3(a) during such Pfizer Year would be calculated as follows:

Royalty for first Product

[ * ]

Royalty for second Product

[ * ]

Total royalty payable for applicable Pfizer Year

[ * ]

(b) Royalty Term. Pfizer’s royalty payment obligations under Section 5.3(a) shall expire, on a Product-by-Product and country-by-country basis, upon the latest of: (i) the expiration of the period during which the use for approved Indications, sale, offer for sale or importation of such Product in such country would absent a license or ownership interest, infringe a Valid Claim in the Licensed Technology in such country (considering Valid Claims of pending patent applications to be issued with the then-pending claims); (ii) the expiration of all Regulatory Exclusivity for such Product in such country; and (iii) fifteen (15) years after the First Commercial Sale of such Product in any Major Market Country (the “Royalty Term”). For the avoidance of doubt, the Royalty Term for a given Product in a given country in the Territory (A) will not begin until the First Commercial Sale of such Product in such country and (B) if not previously expired, will expire immediately upon termination of this Agreement.

(c) Fully Paid-Up, Royalty Free License. Following expiration of the Royalty Term for any Product in a given country, no further royalties will be payable in respect of sales of such Product in such country and, thereafter the license granted to Pfizer under Section 2.1(a)(i) with respect to such Product in such country will automatically become fully paid-up, perpetual, irrevocable and royalty-free.

(d) Royalty Reductions. The following adjustments will be made, on a Product-by-Product and country-by-country basis, to the royalties payable pursuant to Section 5.3(a).

(i) Biosimilar Entry. For any Pfizer Quarter in the applicable Royalty Term for a Product in a country in the Territory during which (1) a Biosimilar Product with respect to such Product is being sold in such country; and (2) the unit volume of such Biosimilar Product sold in such country in such Pfizer Quarter exceeds [ * ] of the combined unit volume of such Product and such Biosimilar Product sold in such country in such Pfizer Quarter, subject to Section 5.3(d)(vi), the royalties payable on Net Sales of such Product in such country in such Pfizer Quarter would be reduced by [ * ] of the amounts of royalties otherwise payable on such Net Sales pursuant to Section 5.3(a) for the remainder of the applicable Royalty Term, such reduction to be prorated appropriately in aggregate for the then-current Pfizer Quarter. The unit volume of the Product and Biosimilar Product shall be calculated using a mutually acceptable method and using market share data provided by a reputable and mutually agreed upon provider, such as IQVIA (f/k/a QuintilesIMS Health).

(ii) Third Party Patents. If Pfizer obtains a license from a Third Party to any Patent Right (other than a Specified Patent) owned by such Third Party in order to Manufacture or Commercialize any Product in a country in the Territory without infringing such Patent Right, whether directly or through any Pfizer Affiliate or Sublicensee, then, subject to Section 5.3(d)(vi), Pfizer shall have the right to deduct, from the royalty payment that would otherwise have been due pursuant to Section 5.3(a) with respect to Net Sales of such Product in such country in a particular Pfizer Quarter, an amount equal to [ * ] of the royalties paid by Pfizer to such Third Party pursuant to such license on account of the sale of such Product in such country during such Pfizer Quarter, such reduction to continue with any amounts not deducted carried over to future Pfizer Quarters until all such amounts have been expended.

(iii) Expiry of Certain Valid Claim Coverage. If with respect to any particular Product in any particular country in the Territory, the Royalty Term for such Product in such country extends beyond the date on which there is no Valid Claim Covering such Product with respect to its sale, offer for sale or importation in such country, then, subject to Section 5.3(d)(vi), the royalties payable on Net Sales of such Product in such country shall be reduced by [ * ] for each Pfizer Quarter for the remainder of the applicable Royalty Term.

(iv) No Adjustment for Certain Sangamo Third Party Agreements. Except as set forth in Schedule 2.1(d), Sangamo will be solely responsible for (i) all obligations (including any royalty or other obligations that relate to the Licensed Technology) under the Current Licenses and under the Exclusive Upstream Licenses and (ii) all payments to inventors of Licensed Technology, including payments under inventorship compensation Laws.

(v) Existing Pfizer Third Party Agreements. Pfizer will be solely responsible for all obligations (including royalty obligations) that relate to Products under its agreements with Third Parties that are in effect on or prior to the Effective Date.

(vi) Notwithstanding the foregoing, during any Pfizer Quarter in the Royalty Term for a Product in a country in the Territory, the operation of Sections 5.3(d)(i), (ii) or (iii) individually or in combination shall not reduce by more than [ * ] the royalties that would otherwise have been due under Section 5.3(a) with respect to Net Sales of such Product in such country during such Pfizer Quarter.

(e) Reports and Payment.

(i) Cumulative Royalties. The obligation to pay royalties under this Agreement will be imposed only once with respect to any sale of any Product.

(ii) Royalty Statements and Payments. Within [ * ] after the end of each Pfizer Quarter during the Royalty Term, Pfizer shall provide Sangamo with a report that contains the following information for the applicable Pfizer Quarter, on a Product-by-Product and country-by-country basis: (1) the amount of gross sales of each Product, (2) an itemized calculation of Net Sales showing deductions provided for in the definition of “Net Sales,” (3) a calculation of the royalty due on such sales, including any reduction made in accordance with Section 5.3(d), and (4) the exchange rate for such country. No such reports will be due for any Product (A) before the First Commercial Sale of such Product or (B) after the Royalty Term for such Product has expired in all countries in the Territory. Pfizer shall pay in Dollars all royalty payments due to Sangamo for such Pfizer Quarter concurrently with the delivery of the royalty report or within [ * ] after the end of each Pfizer Quarter, whichever is sooner, provided that to the extent any royalties are payable by Pfizer hereunder on Net Sales of a Product in a country [ * ] that is [ * ], such royalties payable by Pfizer shall be [ * ] and [ * ].

5.4 Currency; Late Payments. All amounts payable and calculations under this Agreement will be in Dollars. As applicable, Net Sales and any royalty deductions in local currencies will be translated into Dollars in a manner consistent with Pfizer’s normal practices used to prepared its audited financial statements for public financial accounting purposes. If Sangamo does not receive payment of any sum due to it on the date due until [ * ] past such date, interest shall accrue on the sum due from the due date until the date of payment at the rate equal to the [ * ] rate effective for the date that payment was due, as reported by the Wall Street Journal (New York Edition). Such interest shall be computed on the basis of a year of [ * ] for the actual number of days payment is delinquent.

5.5 Invoicing; Method of Payment. Invoices must include the appropriate Pfizer Purchase Order (PO) number (provided that such PO number is provided to Sangamo by Pfizer within [ * ] after the Effective Date or within [ * ] before any payment is due), reference to the Agreement and type of payment due, itemized description of work completed (if applicable), amount owed and name and address to which the payment is to be sent. All invoices shall be clearly marked “INVOICE” and delivered by email to [ * ].

5.6 VAT; Withholding Taxes; Tax Cooperation.

(a) VAT. 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 shall 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 tax is chargeable.

(b) Withholding Taxes. Subject to Section 5.6(d) below, in the event any payments made pursuant to this Agreement become subject to withholding taxes under the laws or regulation of any jurisdiction, the Party making such payment shall deduct and withhold the amount of such taxes for the account of the payee to the extent required by applicable laws or regulations and such amounts payable to the payee shall be reduced by the amount of taxes deducted and withheld. Any such withholding taxes required under applicable laws or regulations to be paid or withheld shall be an expense of, and borne solely by, the payee.

(c) Tax Cooperation. To the extent that the Party making a payment is required to deduct and withhold taxes on any payments under this Agreement, the Party making such payment shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to the payee an official tax certificate or other evidence of such withholding sufficient to enable the payee to claim such payments of taxes. The payee shall provide any tax forms to the Party making such payment that may be reasonably necessary in order for such Party not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. The payee shall use reasonable efforts to provide any such tax forms to the Party making the payment at least [ * ] prior to the due date for any payments for which the payee desires that the Party making the payment apply a reduced withholding rate. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by Law, of withholding taxes, VAT, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or VAT.

(d) Notwithstanding anything in this Agreement to the contrary, (i) if an action (including but not limited to any assignment (including pursuant to Section 12.2), any direction by Pfizer to Sangamo to grant a license or sublicense to any Affiliate of Pfizer pursuant to Section 2.6 (or otherwise), any sublicense of its rights or obligations under this Agreement, any transfer of payment obligations hereunder, or any failure to comply with applicable Laws or filing or record retention requirements) by a Party leads to the imposition of withholding tax liability or VAT on the other Party that would not have been imposed in the absence of such action or in an increase in such liability above the liability that would have been imposed in the absence of such action, then the sum payable by that Party (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that the other Party receives a sum equal to the sum which it would have received had no such action occurred, (ii) otherwise, the sum payable by that Party (in respect of which such deduction or withholding is required to be made) shall be made to the other Party after deduction of the amount required to be so deducted or withheld, which deducted or withheld amount shall be remitted in accordance with applicable law.

5.7 Financial Records and Audit. Each Party shall maintain complete and accurate records in sufficient detail to permit the other Party to confirm the accuracy of the amount of Development and Manufacture costs to be reimbursed, royalty payments and other amounts payable under this Agreement. Upon reasonable prior notice, such records shall be open during regular business hours for a period of [ * ] from the creation of individual records for examination by an independent certified public accountant selected by the auditing Party and reasonably acceptable to the audited Party for the sole purpose of verifying for the auditing Party the accuracy of the financial reports furnished by the audited Party pursuant to this Agreement or of any payments made, or required to be made, by or to the audited Party pursuant to this Agreement. Such audits may occur no more often than [ * ]. Such auditor shall not disclose the audited Party’s Confidential Information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party or the amount of payments to or by the audited Party under this Agreement. Any amounts shown to be owed but unpaid, or overpaid and in need of refund, shall be paid or refunded (as the

case may be) within [ * ] after the accountant’s report, plus interest (as set forth in Section 5.4) from the original due date (unless challenged in good faith by the audited Party). The auditing Party shall bear the full cost of such audit unless such audit reveals an overpayment to, or an underpayment by, the audited Party that resulted from a discrepancy in the financial report provided by the audited Party for the audited period, which underpayment or overpayment is more than [ * ] of the amount set forth in such report, in which case the audited Party shall reimburse the auditing Party for the costs for such audit.

5.8 Confidentiality. Notwithstanding any provision of this Agreement to the contrary all reports and financial information of Pfizer, its Affiliates or its Sublicensees which are provided to or subject to review by Sangamo under this Article 5 will be deemed to be Pfizer’s Confidential Information and subject to the provisions of Article 7.

5.9 No Guarantee of Success. Pfizer and Sangamo acknowledge and agree that payments to Sangamo pursuant to Section 5.2(a) and Section 5.3(a): (a) have been included in this Agreement on the basis that they are only payable or otherwise relevant if the applicable Milestone Event is achieved or Net Sales are made; (b) are solely intended to allocate amounts that may be achieved upon successful Development or Commercialization of such Product as applicable, between Pfizer (who will receive all Product sales revenues) and Sangamo; and (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 for convenience, before any such success is achieved and such amounts become due; and (d) will only be triggered in accordance with the terms and conditions of such provisions. Pfizer and Sangamo further acknowledge and agree that nothing in this Agreement, or in any document or presentation provided by Pfizer to Sangamo or Sangamo to Pfizer prior to the Effective Date will be construed as representing any estimate or projection of (i) the successful Development or Commercialization of any Product under this Agreement, (ii) the number of Products that will or may be successfully Developed or Commercialized under this Agreement, (iii) anticipated sales or the actual value of any 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. Neither Pfizer nor Sangamo makes any representation, warranty or covenant, either express or implied, that (A) it will successfully Develop, Manufacture, Commercialize or continue to Develop, Manufacture or Commercialize any Product in any country, (B) if Commercialized, that any Product will achieve any particular sales level, whether in any individual country or cumulatively throughout the Territory or (C) Pfizer will devote, or cause to be devoted, any level of diligence or resources to Developing or Commercializing any Product in any country, or in the Territory in general, other than is expressly required by the Pfizer Diligence Obligations or the other provisions of this Agreement.

Subject to Pfizer’s rights with respect to Research Program Clinical Candidate Patent Rights pursuant to Section 6.2(a)(iii), Sangamo will have the first right to file, prosecute and maintain the Research Program Patent Rights that are Licensed Patents (the “Licensed Zinc Finger Protein Research Program Patent Rights”) in the Territory at Sangamo’s sole expense using counsel of its own choice reasonably acceptable to Pfizer. Sangamo will keep Pfizer advised on the status of the preparation, filing, prosecution, and maintenance within the [ * ], and upon Pfizer’s written request any other country, of patent applications included within such Licensed Zinc Finger Protein Research Program Patent Rights and the maintenance of any issued patents included within such Licensed Zinc Finger Protein Research Program Patent Rights. Further, Sangamo will consult and reasonably cooperate with Pfizer with respect to the preparation, filing, prosecution and maintenance of such Licensed Zinc Finger Protein Research Program Patent Rights, including: (1) allowing Pfizer a reasonable opportunity and reasonable time to review and comment regarding relevant substantive communications to Sangamo and drafts of any responses or other proposed substantive filings by Sangamo before any applicable filings are submitted to any relevant patent office or Governmental Authority and (2) reflecting any reasonable and timely comments offered by Pfizer in any final filings submitted by Sangamo to any relevant patent office or Governmental Authority. If Sangamo elects to cease the prosecution or maintenance of any Licensed Zinc Finger Protein Research Program Patent Rights, Sangamo will provide Pfizer with written notice not less than [ * ] before any action is required, upon the decision to not continue the prosecution of such patent application or maintenance of such patent. In such event, Sangamo will permit Pfizer to continue prosecution or maintenance of any such Licensed Zinc Finger Protein Research Program Patent Rights in such country at Pfizer’s expense. If Pfizer elects to continue such prosecution or maintenance, (i) Pfizer will promptly identify and engage the attorneys and agents who will conduct further activities on Pfizer’s behalf and Sangamo will reasonably cooperate to promptly transfer the necessary files and execute the necessary forms regarding such transfer, (ii) except as set forth in (i), Sangamo will have no responsibility with respect to the filing, prosecution or maintenance of, or any expenses incurred in connection with, any such Licensed Zinc Finger Protein Research Program Patent Rights following Sangamo’s notice, (iii) Pfizer will keep Sangamo advised on the status of the preparation, filing, prosecution, and maintenance of all such Licensed Zinc Finger Protein Research Program Patent Rights and will reasonably consider any comments made by Sangamo in connection therewith, and (iv) Pfizer will promptly, and no later than [ * ] after written request by Sangamo, by written notice to Sangamo provide a status report of all such Licensed Zinc Finger Protein Research Program Patent Rights.

(iii) Research Program Clinical Candidate Patent Rights. Pfizer will have the first right to file, prosecute and maintain Research Program Clinical Candidate Patent Rights in the Territory using counsel of its own choice reasonably acceptable to Sangamo. For clarity, it is agreed that Pfizer may use internal patent counsel and agents, filing clerks, and paralegals employed by Pfizer, for coordinating worldwide filings of such Patent Rights, for prosecution before the European and Japanese Patent Offices, and for directly instructing any US and ex-US outside counsel and patent agents, including by providing draft applications and responses, and that Pfizer may employ its preferred outside counsel and patent agents to conduct such activities as required for US and ex-US prosecution.

At Pfizer’s request and expense (subject to the next sentence), Sangamo will cooperate and assist Pfizer and outside counsel and agents in the preparation and prosecution of such Research Program Clinical Candidate Patent Rights. Sangamo will be responsible for [ * ] for preparation, prosecution and maintenance of Research Program Clinical Candidate Patent Rights in [ * ] and [ * ] for preparation, prosecution and maintenance of Research Program Clinical Candidate Patent Rights in [ * ].

The Parties will reasonably cooperate to avoid including in Research Program Clinical Candidate Patent Rights any inventions also relevant to zinc finger proteins active against targets other than C9ORF72. In the event that the Parties agree such invention that is relevant to other zinc finger proteins should be disclosed in the same initial filing with an invention that is directed to Compounds, and such invention relevant to other zinc finger proteins is, [ * ], significant with respect to Sangamo’s business, the Parties shall cooperate in each relevant country to (A) [ * ], which for avoidance of doubt may [ * ], (B) [ * ] which [ * ], or (C) take such other action as the

Parties mutually agree [ * ]. All patent applications and patents which (a) issue directly or indirectly from such patent application and (b) solely contain claims that recite at least one zinc finger protein intended to specifically bind C9ORF72 shall be considered Research Program Clinical Candidate Patent Rights and not Licensed Zinc Finger Protein Research Program Rights. The remaining Patent Rights in the relevant patent family shall in all cases be considered Licensed Zinc Finger Protein Research Program Patent Rights for all purposes in the Agreement, including for avoidance of doubt with respect to all prosecution, enforcement, extension and other related provisions.

(iv) Sangamo Patent Rights. Sangamo will have the sole right to file, prosecute and maintain the Sangamo Patent Rights in the Territory at Sangamo’s sole expense. Sangamo will keep Pfizer advised on the status of the preparation, filing, prosecution, and maintenance of all patent applications included within such Sangamo Patent Rights and the maintenance of any issued patents included within such Sangamo Patent Rights. Further, with respect to the Patent Rights listed in Exhibit E (the “Specified Sangamo Patent Rights”), as updated by mutual agreement of the Parties on a time-to-time basis, Sangamo will consult and reasonably cooperate with Pfizer with respect to the preparation, filing, prosecution and maintenance of such Specified Sangamo Patent Rights, including: (i) allowing Pfizer a reasonable opportunity and reasonable time to review and comment regarding relevant substantive communications to Sangamo and drafts of any responses or other proposed substantive filings by Sangamo before any applicable filings are submitted to any relevant patent office or Governmental Authority, including for avoidance of doubt the addition of any Zinc Finger Research Program Know-How to the specification in any refiling, conversion or new filing of a Specified Sangamo Patent Right ([ * ]), and (ii) reflecting any reasonable comments offered by Pfizer in any final filings submitted by Sangamo to any relevant patent office or Governmental Authority. If Sangamo elects to cease the prosecution or maintenance of any Specified Sangamo Patent Right, Sangamo will provide Pfizer with written notice immediately, but not less than [ * ] before any action is required, upon the decision to not continue the prosecution of such patent application or maintenance of such patent. In such event, Sangamo will permit Pfizer to file or continue prosecution or maintenance of any such Specified Sangamo Patent Right in such country at Pfizer’s expense. If Pfizer elects to continue such prosecution or maintenance, (i) Pfizer will promptly identify and engage the attorneys and agents who will conduct further activities on Pfizer’s behalf and Sangamo will reasonably cooperate to promptly transfer the necessary files and execute the necessary forms regarding such transfer, (ii) except as set forth in (i), Sangamo will have no responsibility with respect to the filing, prosecution or maintenance of, or any expenses incurred in connection with, any such Specified Sangamo Patent Right following Sangamo’s notice, (iii) Pfizer will keep Sangamo advised on the status of the preparation, filing, prosecution, and maintenance of all such Specified Sangamo Patent Right and will reasonably consider any comments made by Sangamo in connection therewith, and (iv) Pfizer will promptly, and no later than [ * ] after written request by Sangamo, by written notice to Sangamo provide a status report of all such Specified Sangamo Patent Rights.

(v) Pfizer Patent Rights. Subject to the obligation to coordinate with respect to the filing of Research Program Patent Rights, Pfizer will have the sole right, but no obligation, to file, prosecute and maintain the Patent Rights that it solely owns under this Agreement, in its sole discretion.

(vi) Joint Patent Rights. In the event the Parties make any Joint Know-How that is not Licensed Know-How, the Parties will promptly meet to discuss and determine, based on mutual consent, whether to seek patent protection thereon. Neither Party will file any Joint Patent Right that is not a Licensed Patent without mutual consent. If the Parties decide to seek patent protection for any Joint Know-How that is not Licensed Know-How, they will mutually agree based on each Party’s interests who shall have the right to prepare, file, prosecute, maintain and enforce any such Joint Patent Right throughout the world, as to any sharing of costs, recoveries and royalties therefrom, and as to any further licenses required.

(vii) Patent Term Restoration and Extension. [ * ] right, but not the obligation, to seek, [ * ] if so required, patent term extensions, and supplemental protection certificates and the like available under Law, including 35 U.S.C. § 156 and applicable foreign counterparts, in any country in the Territory in relation to the Licensed Patents. Sangamo and Pfizer will cooperate in connection with all such activities. [ * ], its agents and attorneys will give due consideration to all suggestions and comments of [ * ] regarding any such activities, but in the event of a disagreement between the Parties, [ * ] will have the final decision-making authority; provided, however, that (1) [ * ] will seek [ * ] to extend any Licensed Patent [ * ], including through the use of supplemental protection certificates and the like, [ * ] and (2) without [ * ]’s prior written consent, [ * ] shall not have the right to seek, with respect to any Product and country, any such extension of a Licensed Patent that [ * ] if (A) [ * ] with respect to such Product and country and (B) [ * ], unless [ * ].

(viii) Clarifications. For clarity, (i) prosecution under this Section 6.2 includes opposition, revocation, post-grant review or other patent office proceedings, unless such proceedings are concurrent with Third Party litigation under Section 6.4(a), in which case the provisions of Section 6.4(a) shall govern the Parties’ rights and obligations with respect to such proceedings, and (ii) Third Party declaratory judgment actions or other court actions relating to Patent Rights shall be governed by 6.4(a), and by 6.4(b) if applicable.

(ix) Liability. To the extent that a Party is obtaining, prosecuting or maintaining a Patent Right or otherwise exercising its rights under this Section 6.2, 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.

(x) Recordation. If Pfizer deems it necessary or desirable to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate Governmental Authority(ies) in one or more jurisdictions in the Territory, Sangamo will reasonably cooperate to execute and deliver to Pfizer any documents accurately reflecting or evidencing this Agreement that are necessary or desirable, in Pfizer’s reasonable judgment, to complete such registration or recordation.

6.3 Joint Research Agreement. This Agreement shall 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 Pfizer Licensed Products.

6.4 Enforcement and Defense of Patent Rights.

(a) Enforcement of Sangamo Patent Rights and Licensed Research Program Patent Rights.

(i) Each Party will promptly notify the other in the event of any actual, potential or suspected infringement of a patent under the Sangamo Patent Rights or the Licensed Research Program Patent Rights by any Third Party.

(ii) As between Pfizer and Sangamo, Pfizer will have the first right, but not the obligation, to institute litigation or take other steps to remedy infringement in connection with the Research Program Clinical Candidate Patent Rights in the Territory with respect to activities competitive or relevant to those of Pfizer under this Agreement (an “RPCCPR Infringement”), and any such litigation or steps will be at Pfizer’s expense; provided that any infringement recoveries resulting from such litigation or steps relating to a claim of RPCCPR Infringement, after deducting Pfizer’s out of pocket expenses (including counsel fees and expenses) in pursuing such claim, will be [ * ]. Pfizer will not, without the prior written consent of Sangamo, enter into any compromise or settlement relating to such litigation that (i) admits the invalidity or unenforceability of any Sangamo Patent Right or Research Program Patent Right or (ii) requires Pfizer or Sangamo to abandon any Sangamo Patent Right or Research Program Patent Right. Sangamo, upon request of Pfizer, agrees to timely commence or to join in any such litigation, at Pfizer’s expense, and in any event to cooperate with Pfizer in such litigation or steps at Pfizer’s expense. Sangamo will have the right to consult with Pfizer about such litigation and to participate in and be represented by independent counsel in such litigation at Sangamo’s own expense. If Pfizer fails to institute and prosecute an action or proceeding to xxxxx any RPCCPR Infringement within a period of [ * ] after the first notice of such RPCCPR Infringement under Section 6.4(a)(i) (or such shorter period as may be necessary to bring or defend and maintain such action without loss of rights), then upon Pfizer’s written consent (not to be unreasonably withheld), Sangamo shall have the second right, but not the obligation, to commence a suit or take other action to enforce the applicable Research Program Clinical Candidate Patent Right against such RPCCPR Infringement at its own cost and expense.

(iii) As between Pfizer and Sangamo, Sangamo will have the first right, but not the obligation, to institute litigation or take other steps to remedy infringement in connection with the Licensed Research Program Patent Rights or Sangamo Patent Rights in the Territory with respect to a Third Party’s Manufacture, use, importation, offer for sale or sale, or other exploitation, of any gene therapy product that is directed to C9ORF72 other than an RPCCPR Infringement (an “C9ORF72 Infringement”), and any such litigation or steps will be at Sangamo’s expense. Pfizer, upon request of Sangamo, agrees to timely join in any such litigation, at Sangamo’s expense, and in any event to cooperate with Sangamo in such litigation or steps at Sangamo’s expense. Pfizer will have the right to consult with Sangamo about such

litigation and to be represented by independent counsel in such litigation at Pfizer’s own expense. If Sangamo fails to institute and prosecute an action or proceeding to xxxxx any C9ORF72 Infringement within a period of [ * ] after the first notice of such C9ORF72 Infringement under Section 6.4(a)(i) (or such shorter period as may be necessary to bring or defend and maintain such action without loss of rights), then upon Sangamo’s written consent (not to be unreasonably withheld), Pfizer shall have the second right, but not the obligation, to commence a suit or take other action to enforce the applicable Licensed Research Program Patent Right or Sangamo Patent Right against such C9ORF72 Infringement at its own cost and expense; provided that any infringement recoveries resulting from such litigation or steps relating to a claim of C9ORF72 Infringement, after deducting Pfizer’s out of pocket expenses (including counsel fees and expenses) in pursuing such claim, will be deemed 1) [ * ] in the case of assertion of Licensed Research Program Patent Rights and 2) [ * ] in the case of Sangamo Patent Rights. For avoidance of doubt, Pfizer shall have no second right to remedy infringement of Licensed Research Program Patent Rights or Sangamo Patent Rights in each case other than with respect to a gene therapy product directed to C9ORF72.

(b) Enforcement of Pfizer Patent Rights. Pfizer will have the sole right, but no obligation, to take action to obtain a discontinuance of infringement or bring suit against a Third Party infringing or challenging the validity or enforceability of any Pfizer Patent Right.

(c) Biosimilar Notices.

(i) Sangamo Cooperation. Upon Pfizer’s request, Sangamo will use Commercially Reasonable Efforts to assist and cooperate with Pfizer in (A) establishing a strategy for responding to requests for information from Regulatory Authorities and Third Party requestors and (B) 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.

(ii) Compliance with Biosimilar Notices. Pfizer will have the sole right in its discretion to comply with the applicable provisions of 42 U.S.C. § 262(l) (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 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, Sangamo will have the right to review the patent information included in such proposed submission, solely with respect to Sangamo Patent Rights and Research Program Patent Rights, and to make suggestions as to any changes to such patent information that Sangamo reasonably believes to be necessary; provided further that Pfizer will determine the final content of any such submission to the extent it is related to Research Program Clinical Candidate Patent Rights or Patent Rights that are owned by Pfizer. In the case of a 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 Product, will be the “reference product sponsor” under the PHS Act. Pfizer will give written notice to Sangamo of receipt of a Biosimilar Notice received by Pfizer with respect to a Product, and Pfizer will consult with Sangamo with respect to the selection of any Sangamo Patent Rights or Research Program Patent Rights to be submitted pursuant to 42 U.S.C. § 262(l) (or any similar law in any country of the Territory outside the United States); provided that (1) [ * ] pursuant to 42 U.S.C. § 262(l)(3)(A) and (2) [ * ], (A) agree pursuant to 42 U.S.C. § 262(l)(4) that [ * ] or (B) or [ * ] pursuant to 42 U.S.C. § 262(l)(5). Sangamo agrees to be bound and will cause its Affiliates and all Third Party Licensors to be bound by the confidentiality provisions of 42 U.S.C. § 262(l)(1)(B)(iii). Solely to the extent any Sangamo Patent Rights or Research Program Patent Rights are involved in any such action brought pursuant to 42 U.S.C. § 262(l), the Parties’ rights and responsibilities regarding any action will be determined in accordance with Section 6.4(a).

(d) Other Actions by Third Parties. Each Party will promptly notify the other Party in the event of any legal or administrative action by any Third Party involving any Sangamo Patent Right or Licensed Research Program Patent Right of which it becomes aware, including any nullity, revocation, interference, reexamination or compulsory license proceeding. Sangamo will have the sole right, but no obligation, to defend against any such action involving any Sangamo Patent Right, in its own name (to the extent permitted by applicable Law), and any such defense will be at Sangamo’s expense. Sangamo will have the first right, but no obligation, to defend against any such action involving any Licensed Research Program Patent Right other than a Research Program Clinical Candidate Patent Right, in its own name (to the extent permitted by applicable Law), and any such defense will be at Sangamo’s expense. Pfizer, upon Sangamo’s request, agrees to join in any such action at Sangamo’s expense and in any event to cooperate with Sangamo at Sangamo’s expense. If Sangamo fails to defend against any such action involving a Licensed Research Program Patent Right, then Pfizer will have the right to defend such action, in its own name, and any such defense will be at Pfizer’s expense. Pfizer will have the first right, but no obligation, to defend against any such action involving any Research Program Clinical Candidate Patent Right, in its own name (to the extent permitted by applicable Law), and any such defense will be at Pfizer’s expense. Sangamo, upon Pfizer’s request, agrees to join in any such action at Pfizer’s expense and in any event to cooperate with Pfizer at Pfizer’s expense. If Pfizer fails to defend against any such action involving a Research Program Clinical Candidate Patent Right, then Sangamo will have the right to defend such action, in its own name, and any such defense will be at Sangamo’s expense.

(e) Purple Book Listings. To the extent of any Sangamo Patent Rights or Licensed Research Program Patent Rights Covering a Product, the Parties shall cooperate with each other to enable Pfizer to make filings with Regulatory Authorities, as required or allowed in connection with (i) in the United States, the FDA’s Purple Book and the Biologics Price Competition and Innovation Act and (ii) outside the United States, under the national implementations of Article 10.1(a)(iii) of Directive 2001/EC/83 or other international equivalents thereof. Pfizer shall consider Sangamo’s reasonable requests in connection therewith, including meeting any submission deadlines, in each case, to the extent required or permitted by Applicable Law.

(f) Allegations of Infringement and Right to Seek Third Party Licenses.

(i) Notice. If the Development, Manufacture, Commercialization or use of any Compound or Product (collectively, the “Licensed Activities”) by Pfizer or any of its Affiliates or Sublicensees is alleged by a Third Party to infringe, misappropriate or otherwise violate such Third Party’s Patent Rights or other Intellectual Property Rights or Sangamo otherwise identifies any Third Party Patent Rights or other Intellectual Property Rights that may be infringed, misappropriated or otherwise violated by such activities, Sangamo will, promptly upon becoming aware of such allegation or identification, notify Pfizer in writing.

(ii) Pfizer Option to Negotiate. If Pfizer determines, in its sole discretion, that, in order for Pfizer, its Affiliates or Sublicensees to engage in the Licensed Activities, it is necessary or desirable to obtain a license under one or more Patent Rights or other Intellectual Property Rights Controlled by a Third Party (collectively, “Third Party IP Rights”), then Pfizer will have the right, but not the obligation, to negotiate and enter into a license or other agreement with such Third Party.

(g) Third Party Infringement Suits. Each of the Parties will promptly notify the other in the event that any Third Party files any suit or brings any other action alleging patent infringement by Pfizer or Sangamo or any of their respective Affiliates or Sublicensees with respect to the Development, Manufacture, Commercialization or use of any Compound or Product (any such suit or other action referred to herein as an “Infringement Claim”). In the case of any Infringement Claim for which a Party has an obligation to indemnify the other Party pursuant to Section 10.1 or 10.2, the Parties shall comply with the terms of Sections 10.1, 10.2 and 10.3, as applicable.

(c) the Receiving Party may only disclose Confidential Information of the other Party to: (i) its Affiliates, licensees and Sublicensees; and (ii) employees, directors, agents, contractors, consultants and advisers of the Receiving Party and its Affiliates and Sublicensees, in each case to the extent reasonably necessary for the purposes of performing its obligations or exercising its rights under this Agreement; provided that such Persons are bound by legally enforceable obligations to maintain the confidentiality of the Confidential Information in a manner consistent with the confidentiality provisions of this Agreement; and

(d) the terms and conditions of this Agreement will be considered Confidential Information of both Parties.

7.2 Exceptions. The foregoing obligations as to particular Confidential Information of a Disclosing Party shall not apply to the extent that the Receiving Party can demonstrate that such Confidential Information:

(d) is discovered or developed by the Receiving Party independently and without use of or reference to any Confidential Information received from the Disclosing Party, as documented by the Receiving Party’s business records.

Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the Receiving Party unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the Receiving Party.

7.3 Authorized Disclosures. Notwithstanding the obligations set forth in Sections 7.1 and 7.6, a Party may disclose the other Party’s Confidential Information (including this Agreement and the terms herein) to the extent:

(a) such disclosure is reasonably necessary: (i) to such Party’s directors, attorneys, independent accountants or financial advisors for the sole purpose of enabling such directors, attorneys, independent accountants or financial advisors to provide advice to such Party, provided that in each such case such recipients are bound by confidentiality and non-use obligations that are at least as restrictive as those contained in this Agreement; and provided further that the term of confidentiality for recipients may be shorter as long as it is no less than five (5) years; or (ii) to actual or potential investors, acquirors, licensees and other financial or commercial partners solely for the purpose of evaluating or carrying out an actual or potential investment, acquisition or collaboration, provided that in each such case such recipients are bound by confidentiality and non-use obligations at least as restrictive as those contained in the Agreement; and provided further that the term of confidentiality for recipients may be shorter as long as it is no less than [ * ];

(c) such disclosure is required by Law, judicial or administrative process, provided that except for disclosures governed by the last two sentences of Section 7.4, in such event such Party shall promptly inform the other Party of such required disclosure and provide the other Party an opportunity to challenge or limit the disclosure obligations, provided that Confidential Information that is disclosed pursuant to Section 7.3(b) or this Section 7.3(c) shall remain otherwise subject to the confidentiality and non-use provisions of this Article 7 (provided that such disclosure is not a public disclosure), and the Party disclosing Confidential Information to a Governmental Authority or pursuant to Law or court order shall cooperate with and reasonably assist the other Party (at the other Party’s cost) if the other Party seeks a protective order or other remedy in respect of any such disclosure and furnish only that portion of the Confidential Information which, in the opinion of Party’s legal counsel, is responsive to such requirement or request;

(d) necessary in order to enforce its rights under the Agreement; or

(e) such disclosure is by Sangamo and is required pursuant to the terms of any Sangamo Third Party Agreement.

Before disclosing this Agreement or any of the terms hereof pursuant to this Section 7.4, the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure, with the disclosing Party providing as much advance notice as is feasible under the circumstances, and giving consideration to the timely comments of the other Party. Further, if a Party discloses this Agreement or any of the terms hereof in accordance with this Section 7.4, such Party will, at its own expense, seek such confidential treatment of confidential portions of this Agreement and such other terms as it reasonably determines, giving consideration to the comments of the other Party pursuant to the preceding sentence.

7.5 Technical Publication. Neither Party may publish peer reviewed manuscripts, or give other forms of public disclosure such as abstracts and presentations, of results of studies carried out under this Agreement, without the opportunity for prior review by the other Party, except to the extent required by applicable Laws.

In addition, the Party seeking publication shall delay the submission for a period up to [ * ] in the event that the other Party can demonstrate reasonable need for such delay, including without limitation, the preparation and filing of a patent application. If the other Party fails to provide its comments to the Party seeking publication within such fourteen [ * ] period, such other Party shall be deemed to not have any comments, and the Party seeking publication shall be free to publish in accordance with this Section 7.5 after the [ * ] period has elapsed. The Party seeking publication shall provide the other Party a copy of the manuscript at the time of the submission. Each Party agrees to acknowledge the contributions of the other Party and its employees in all publications as scientifically appropriate. Notwithstanding anything in this Agreement to the contrary, nothing will prevent Pfizer from making any scientific publication or public announcement with respect to any approved Product(s) under this Agreement; provided, however, that Pfizer will comply with this Section 7.5 and, except as permitted under Sections 7.2 and 7.3, Pfizer will not disclose any of Sangamo’s Confidential Information in any such publication or announcement without obtaining Sangamo’s prior written consent to do so (such consent not to be unreasonably withheld).

(b) Other than the joint press release pursuant to Section 7.6(a) and disclosures under Section 7.4, the Parties agree that any other news release or other public announcement relating to this Agreement or the performance hereunder that would disclose information other than that already in the public domain shall first be reviewed and approved by both Parties (with such approval not to be unreasonably withheld or delayed); provided, however, that notwithstanding the foregoing, Sangamo shall have the right to disclose publicly (including in its securities filings and earning calls) [ * ]; provided further that Pfizer will have at least [ * ] to review and provide edits and comments to any public disclosure proposed by Sangamo under this sentence and Sangamo will reasonably incorporate any edits and address any comments provided by Pfizer in such proposed public disclosure.

7.7 Obligations in Connection with Change of Control. If Sangamo is subject to a Change of Control, Sangamo will, and it will cause its Representatives to, ensure that no Confidential Information of Pfizer is released to (a) any Affiliate of Sangamo that becomes an Affiliate as a result of the Change of Control or (b) any other Representatives of Sangamo (or of the relevant surviving entity of such Change of Control) who become Representatives of Sangamo as a result of the Change of Control, unless such Affiliate or other Representatives, as applicable, have signed individual confidentiality agreements which include equivalent obligations to those set out in this Article 7. If any Change of Control of Sangamo occurs, Sangamo 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.

ARTICLE 8

TERM AND TERMINATION

8.1 Term. The term of this Agreement shall commence upon the Effective Date and continue in full force and effect, on a Product-by-Product and country-by-country basis, until the expiration of the Royalty Term for such Product in such country, unless earlier terminated as set

8.2 Termination.

(a) Termination by Pfizer for Convenience. Pfizer may terminate this Agreement on a Product-by-Product or country-by-country basis, or in its entirety, without cause, for any or no reason, by providing written notice of termination to Sangamo, which notice includes an effective date of termination at least [ * ] prior written notice to Sangamo during the Research Term, [ * ] prior written notice to Sangamo after the Research Term but prior to Commercialization of a Product, and [ * ] prior written notice to Sangamo after the commencement of the Commercialization of a Product.

For all breaches other than a failure to make a payment as set forth in this Agreement, the allegedly breaching Party shall have [ * ] from such Breach Notice to cure such breach, provided, however, that if any breach is not reasonably curable within [ * ] and the allegedly breaching Party is making a bona fide effort to cure such breach, such termination will be delayed for a time period to be agreed by both Parties in order to permit the allegedly breaching Party a reasonable period of time to cure such breach, not to exceed an additional [ * ]. For any breach arising from a failure to make a payment set forth in this Agreement, the cure period will be [ * ] and such cure period will be tolled pending resolution of any bona fide dispute between the Parties as to whether such payment is due.

(a) the material breach of any representation, warranty or covenant by Sangamo under this Agreement; or

(b) the recklessness, negligence or intentional misconduct of any Sangamo Indemnitees;

except, in each case, to the extent caused by the negligence or intentional misconduct of any Pfizer Indemnitees or a material breach by Pfizer of any of its representations, warranties or covenants set forth in this Agreement.

10.2 Indemnification by Pfizer. Pfizer shall indemnify, defend and hold harmless Sangamo and its Affiliates, Upstream Licensors and each of their respective directors, officers, employees and agents (collectively “Sangamo Indemnitees”), from and against all Liabilities to the extent resulting from any claims, demands, actions or other proceedings by any Third Party arising out of:

(a) the material breach of any representation, warranty or covenant by Pfizer under this Agreement;

(b) the recklessness, negligence or intentional misconduct of any Pfizer Indemnitees;

(c) the research, Development, Manufacture, and Commercialization of the Products and Companion Diagnostic Assays by or on behalf of Pfizer or its Affiliates or Sublicensees;

except, in each case, to the extent caused by the negligence or intentional misconduct of any Sangamo Indemnitees or a material breach by Sangamo of any of its representations, warranties or covenants set forth in this Agreement.

10.3 Indemnification Procedure.

(a) Notice. If either Party is seeking indemnification under Section 10.1 or 10.2 (the “Indemnified Party”), it shall promptly inform the other Party (the “Indemnifying Party”) of the claim giving rise to the obligation to indemnify pursuant to such Section as soon as reasonably practicable after receiving notice of the claim, 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.

(b) Control. The Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within [ * ] after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume the direction and control of the defense, litigation, settlement, appeal or other disposition of any such claim for which it is obligated to indemnify the Indemnified Party (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, to satisfy the amount of any adverse monetary judgment that is sought, (b) the 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 claim in full (the conditions set forth in clauses (a), (b) and (c) above are collectively referred to as the “Litigation Conditions”). 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 shall cooperate with the Indemnifying Party, and will cause its Affiliates and agents to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the 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 [ * ] 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, shall have the right to participate (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense and with counsel of its choice, in the defense of any claim that has been assumed by the other Party.

(c) 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 claim, on such terms and conditions as it deems reasonably appropriate, to the extent such claim involves equitable or other non-monetary relief, but will not have the right to settle such claim to the extent such claim involves monetary damages without the prior written consent of the Indemnifying Party. Neither the Indemnifying Party nor the Indemnified Party will make any admission of liability in respect of any claim without the prior written consent of the other party, and the Indemnified Party will use reasonable efforts to mitigate Liabilities arising from such claim. If the Parties cannot agree as to the application of Section 10.1 or 10.2 as to any claim, pending resolution of such dispute, the Parties may conduct separate defenses of such claims, with each Party retaining the right to claim indemnification from the other Party in accordance with Section 10.1 or 10.2 upon resolution of the underlying claim.

10.4 Mitigation of Loss. Each Indemnified Party shall take and shall procure that its Affiliates take all such reasonable steps and action as are reasonably necessary or as the Indemnifying Party may reasonably require in order to mitigate any claims (or potential losses or damages) under this Article 10. Nothing in this Agreement shall or shall be deemed to relieve any Party of any common law or other duty to mitigate any losses incurred by it.

10.5 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 10.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 10.1 OR 10.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS IN ARTICLE 7.

10.6 Insurance. Each Party shall procure and maintain, during the Term, commercial general liability insurance, including product liability insurance, with minimum “A-” Best rated insurance carriers to cover its indemnification obligations under Section 10.1 or Section 10.2, as applicable, in each case with limits of not less than [ * ] per occurrence and in the aggregate. All deductibles and retentions will be the responsibility of the named insured. Pfizer and its Affiliates will be an additional insured on Sangamo’s commercial general liability and products liability policies, and be provided with a waiver of subrogation. To the extent of its culpability, all coverages of Sangamo will be primary and non-contributing with any similar insurance, carried by Pfizer. Each Party shall provide the other Party with evidence of such insurance by furnishing a certificate of insurance upon request and shall provide the other Party with written notice at least [ * ] prior to the cancellation, non-renewal or material changes in such insurance. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 10. Notwithstanding any provision of this Section 10.6 to the contrary, Pfizer may meet its obligations under this Section 10.6 through self-insurance. Neither Party’s insurance will be construed to create a limit of liability with respect to its indemnification obligations under this Article 10.

ARTICLE 11

ANTITRUST

11.1 Approvals. Each of Sangamo and Pfizer will cooperate with the other Party and use Commercially Reasonable Efforts to make all registrations, filings and applications, to give all notices and to obtain as soon as practicable all governmental or other consents, transfers, approvals, orders, qualifications authorizations, permits and waivers, if any, and to do all other things necessary or desirable for the consummation of the transactions as contemplated hereby.

ARTICLE 12

GENERAL PROVISIONS

12.1 Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, potentially including embargoes, war, acts of war (whether war be declared or not), acts of terrorism, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, earthquakes or other acts of God, or acts, generally applicable action or inaction by any governmental authority (but excluding any government action or inaction that is specific to such Party, its Affiliates or Sublicensees, such as revocation or non-renewal of such Party’s license to conduct business), or omissions or delays in acting by the other Party. The affected Party shall notify the other Party in writing of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake and continue diligently all Commercially Reasonable Efforts necessary to cure such force majeure circumstances or to perform its obligations in spite of the ongoing circumstances.

12.2 Assignment. This Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by either Party without the prior written consent of the other Party. Notwithstanding the foregoing, subject to the provisions of Section 12.3, as applicable, either Party may, without consent of the other Party, assign this Agreement and its rights and obligations hereunder in whole or in part to an Affiliate of such Party, or in whole to its successor in interest in connection with the sale of all or substantially all of its stock or its assets to which this Agreement relates, or in connection with a merger, acquisition or similar transaction provided that such sale is not primarily for the benefit of its creditors. In addition, Pfizer may assign its rights and obligations under this Agreement to a Third Party where Pfizer or its Affiliate is required, or makes a good faith determination based on advice of counsel, to divest a Product in order to comply with Law or the order of any Governmental Authority as a result of a merger or acquisition. Each Party will promptly notify the other Party of any assignment or transfer under the provisions of this Section 12.2. Any attempted assignment not in accordance with the foregoing shall be null and void and of no legal effect. Any permitted assignee shall assume all assigned obligations of its assignor under this Agreement.

12.6 Dispute Resolution.

(a) Informal Dispute Resolution; Arbitration. The Parties recognize that disputes as to certain matters may from time to time arise that relate to either Party’s rights and/or obligations hereunder, including the interpretation, alleged breach, enforcement, termination or validity of this Agreement (a “Dispute”). For clarity, Dispute shall not include matters within the JRC’s authority, which shall be resolved in accordance with Section 3.3. It is the objective of the Parties to establish procedures to facilitate the resolution of such Disputes arising under this Agreement in an expedient manner by mutual cooperation. To accomplish this objective, the Parties agree that if a Dispute arises under this Agreement, and the Parties are unable to resolve such Dispute within [ * ] after such Dispute is first identified by either Party in writing to the other, the Parties shall refer such Dispute to the Executive Officers of the Parties for attempted resolution by good faith negotiations within [ * ] after such notice is received. If the Executive Officers are not able to resolve such Dispute within [ * ], then such Dispute (other than Excluded Claim as defined in Section 12.6(f) below) shall be finally resolved by binding arbitration administered by [ * ] pursuant to [ * ], and judgment on the arbitration award may be entered in any court having jurisdiction thereof.

(b) Number of Arbitrators; Arbitral Seat. The arbitration shall be conducted by a panel of three arbitrators experienced in the pharmaceutical business: within [ * ] after initiation of arbitration, each Party shall select one person to act as arbitrator; provided that if a Party fails to appoint an arbitrator within [ * ] of the arbitration being initiated, such appointment shall be made by [ * ]. The two arbitrators appointed in accordance with the preceding sentence shall appoint the third arbitrator, who shall be the chairman of the tribunal. If the arbitrators selected pursuant to the first sentence of this Section 12.6(b) are unable or fail to agree upon the third arbitrator within [ * ] of the appointment of the second arbitrator, the third arbitrator shall be appointed by [ * ]. The place of arbitration shall be [ * ]; all proceedings and communications shall be in English.

(c) Powers of the Arbitrators. The arbitrators shall have the discretion to hear and determine at any stage of the arbitration any issue asserted by any Party to be dispositive of any claim or counterclaim, in whole or part, in accordance with such procedure as the arbitrators may deem appropriate, and the arbitrators may render an award on such issue. In addition to the authority conferred on the arbitrators by the [ * ] rules, and without prejudice to any provisional measures that may be available from a court of competent jurisdiction, the arbitrators shall have the power to grant any provisional measures that the arbitrators deem appropriate, including but not limited to provisional injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved and any provisional measures ordered by the arbitrators may, to the extent permitted by applicable Law, be deemed to be a final award on the subject matter of the measures and shall be enforceable as such. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any

injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators are authorized to award to the prevailing Party, if any, as determined by the arbitrators, their costs and expenses. The arbitrators shall have no authority to award punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees of arbitration, except as provided above.

(d) Statute of Limitations. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by the applicable New York statute of limitations.

(e) Confidentiality. No information concerning an arbitration, beyond the names of the Parties and the relief requested, may be unilaterally disclosed to a Third Party by any Party unless required by Law. Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. Any documentary or other evidence given by a Party or witness in the arbitration shall be treated as confidential by any Party whose access to such evidence arises exclusively as a result of its participation in the arbitration, and shall not be disclosed to any Third Party (other than a witness or expert), except as may be required by Law.

(f) Excluded Claims. As used in this Section, the term “Excluded Claim” shall mean a dispute, controversy or claim that concerns (i) the scope, validity, enforceability, inventorship or infringement of a patent, patent application, trademark or copyright; or (ii) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

Sangamo and Pfizer announce collaboration for development of zinc finger protein gene therapy for ALS

Richmond, California and New York, New York, January 3, 2018 – Sangamo Therapeutics, Inc. (Nasdaq: SGMO) and Pfizer Inc. (NYSE: PFE) today announced a collaboration for the development of a potential gene therapy using zinc finger protein transcription factors (ZFP-TFs) to treat amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) linked to mutations of the C9ORF72 gene.

ALS and FTLD are part of a spectrum of neurodegenerative disorders caused by mutations in the C9ORF72 gene that involve hundreds of additional repetitions of a six base pair sequence of DNA. This ultimately leads to the deterioration of motor neurons, in the case of ALS, or neurons in the frontal and temporal lobes, in the case of FTLD. Currently, there are no cures to halt or reverse the progression of ALS or FTLD. The C9ORF72 mutation is linked to approximately one-third of cases of familial ALS.

“We are excited to continue our collaborative relationship with Pfizer with this new program using Sangamo’s zinc finger protein technology to develop a potential gene therapy for patients with certain forms of ALS and FTLD, devastating diseases with very limited treatment options,” said Xx. Xxxxx Xxxxxx, Chief Executive Officer of Sangamo. “The precision and flexibility of zinc finger proteins enables targeting of virtually any genetic mutation. Collaboration with the right partner for a given therapeutic application is a key component of our corporate strategy and enables us to pursue the vast opportunity set of our platform.”

“We look forward to working with Sangamo on potential treatments for devastating diseases related to genetic mutations of the C9ORF72 gene,” said Xxxx XxXxxx, Senior Vice President and Chief Scientific Officer, Pfizer Rare Disease. “Pfizer is proud of the progress we have made in the area of gene therapy, which offers tremendous promise to patients and their families.”

Gene therapies are a potentially transformational technology for patients, focused on highly specialized, one-time treatments that address the root cause of diseases caused by genetic mutation. Sangamo’s ZFP-TF technology involves introducing an engineered zinc finger protein (ZFP) which is designed to identify and bind to a precise sequence of DNA. Once bound to the target sequence of DNA, a transcriptional repressor domain attached to the ZFP suppresses

expression of the gene. Under this collaboration, Sangamo and Pfizer will investigate allele-specific ZFP-TFs with the potential to differentiate the mutant C9ORF72 allele from the wild type allele and to specifically down-regulate expression of the mutant form of the gene.

Under the terms of the collaboration agreement, Sangamo will receive a $12 million upfront payment from Pfizer. Sangamo will be responsible for the development of ZFP-TF candidates. Pfizer will be operationally and financially responsible for subsequent research, development, manufacturing and commercialization for the C9ORF72 ZFP-TF program and any resulting products. Sangamo is eligible to receive potential development and commercial milestone payments of up to $150 million, as well as tiered royalties on net sales.

In May 2017, Sangamo and Pfizer entered into an exclusive, global collaboration and license agreement for the development and commercialization of potential gene therapy products for Hemophilia A, including SB-525, which entered the clinic in August 2017.

About Sangamo’s ZFP-TF Gene Regulation Platform

Sangamo’s zinc finger protein transcription factor (ZFP-TF)-mediated gene regulation approach is designed to either selectively repress (down-regulate) or activate (up-regulate) the expression of a specific gene or DNA sequence with a single administration. This technology enables targeting of a broad range of diseases requiring regulation of endogenous gene expression and differs from other approaches such as gene therapy or zinc finger nuclease-mediated genome editing, which are designed to replace or correct a missing or mutated gene or DNA sequence. Sangamo is developing ZFP-TFs as a novel therapeutic approach for diseases of the central nervous system (CNS). In keeping with the company’s strategy to externalize development of ZFP-TFs for CNS diseases, Sangamo has established collaborations with Pfizer for ALS and FTLD and with Shire for Huntington’s disease. Sangamo is also developing ZFP-TFs to down-regulate the expression of tau, a protein associated with Alzheimer’s disease and frontotemporal dementia (FTD). The company’s strategy for the tau program is to seek a development and commercialization partner upon completion of preclinical studies.
