(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;

(ii)a non-exclusive, royalty-free, fully paid-up license (or sublicense, as applicable), with the right to sublicense solely to Pfizer’s Affiliates and to contractors working on behalf of Pfizer or its Affiliates, under the Licensed Technology, to research Additional Products up to but not including [*], during the Exclusivity Period. For clarity, the foregoing license (1) does not include the right to [*] any Additional Product; (2) does not include the right to perform research, without Sangamo’s prior written consent, on any Additional Product that [*]; and (3) shall expire at the end of the Exclusivity Period;

(iii)a non-exclusive, fully paid, worldwide, perpetual and irrevocable license, with the right to sublicense solely as provided in Section 2.1(b)(iii), under the Sangamo Manufacturing Improvements, to make and have made any and all products researched or developed by Pfizer or its Affiliates [*] (each a “Pfizer Product”) and to use, have used, import, have imported, offer for sale, have offered for sale, have sold and sell such Pfizer Products; and

(iv)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 (iv)), 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 (1) for the purpose of predicting or monitoring [*] and (2) with respect to any Companion Diagnostic Assay that has been developed in accordance with the preceding clause (1), for the purpose of predicting or monitoring [*]. Notwithstanding any provision to the contrary in this Agreement, the license granted under Section 2.1(a)(iv)(2) hereof shall be [*]. To the extent that Pfizer or its Affiliate or Sublicensee conducts any development or commercialization of a Companion Diagnostic Assay which was developed using Licensed Companion Diagnostic Technology through a Third Party, Pfizer shall use reasonable efforts to facilitate Sangamo’s access to such Companion Diagnostic Assay through such Third Party. For clarity, [*].

(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)(iv) 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 thirty (30) days 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.

(iii)Subject to the terms and conditions of this Agreement, Pfizer may, upon written notice to Sangamo, grant sublicenses under the license granted by

Sangamo to Pfizer under Section 2.1(a)(iii) to its Affiliates or Third Parties (through one or more tiers) to whom Pfizer assigns or grants a license under intellectual property rights of Pfizer (other than intellectual property rights licensed by Sangamo to Pfizer under this Agreement) with respect to a Pfizer Product, 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. For clarity, Pfizer shall have no right to grant any sublicense under the Sangamo Manufacturing Improvements to make, use or sell any product that is not a Pfizer Product and, in the event Pfizer does grant any such sublicense in violation of this Section 2.1(b)(iii), Sangamo shall have the right to terminate the license granted to Pfizer under Section 2.1(a)(iii).

(iv)Pfizer shall provide Sangamo with written notice of each executed sublicense agreement entered into pursuant to Section 2.1(b)(iii) within thirty (30) days after execution thereof, such notice to include the name of the Sublicensee and a description of the applicable Pfizer Product and sublicense scope, which shall be treated by Sangamo as Pfizer’s Confidential Information.

(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. In addition, subject to Section 2.5, Sangamo retains the exclusive right to practice and license the Licensed Technology, Sangamo Manufacturing Improvement Technology and Licensed Companion Diagnostic Technology outside the scope of the licenses granted to Pfizer under Section 2.1(a).

(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 (i.e. those terms set forth on Schedule 2.1(d), which may be amended by 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. 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.

(a)License Grants. Subject to the terms and conditions of this Agreement, Pfizer hereby grants to Sangamo and its Affiliates:

(i) a non-exclusive, fully paid, royalty-free, worldwide license, with the right to grant sublicenses only to its Affiliates and subcontractors, under all Know-How, Patent Rights and other intellectual property rights Controlled by Pfizer and its Affiliates as of the Effective Date or during the Term, solely to perform Sangamo’s and its Affiliates’ obligations under this Agreement; and

(ii)a non-exclusive, fully paid and royalty-free (subject to Section 2.2(c), worldwide, perpetual and irrevocable (subject to Section 2.2(b)(i) and Section 2.2(c)) license, with the right to sublicense solely as provided in Section 2.2(b), under the Pfizer Manufacturing Improvements and Pfizer Manufacturing Technology, to make and have made any and all products researched or developed by Sangamo [*] (each a “Sangamo Product”) and to use, have used, import, have imported, offer for sale, have offered for sale, have sold and sell such Sangamo Products.

(i)Subject to the terms and conditions of this Agreement, Sangamo may, upon written notice to Pfizer, grant sublicenses under the licenses granted by Pfizer to Sangamo under Section 2.2(a)(ii) to its Affiliates or Third Parties (through one or more tiers) to whom Sangamo assigns or grants a license under intellectual property rights of Sangamo (other than intellectual property rights licensed by Pfizer to Sangamo under this Agreement) with respect to a Sangamo Product, respectively; provided that Sangamo shall remain responsible for the performance of all of its Sublicensees to the same extent as if such activities were conducted by Sangamo, and shall remain responsible for any and all payments due hereunder, if any, with respect to activities of any such Sublicensees. For clarity, Sangamo shall have no right to grant any sublicense under the Pfizer Manufacturing Improvements or Pfizer Manufacturing Technology to make, use or sell any product that is not a Sangamo Product and, in the event Sangamo does grant any such sublicense in violation of this Section 2.2(b)(i), Pfizer shall have the right to terminate the license granted to Sangamo under Section 2.2(a)(ii).

(ii)Sangamo shall provide Pfizer with written notice of each executed sublicense agreement entered into pursuant to Section 2.2(b)(i) within thirty (30) days after execution thereof, such notice to include the name of the Sublicensee and a description of the applicable Sangamo Product and sublicense scope, which shall be treated by Pfizer as Sangamo’s Confidential Information.

(c)Costs. In the event that any Pfizer Manufacturing Technology is licensed to Pfizer by a Third Party, Pfizer shall notify Sangamo promptly after disclosing such Pfizer Manufacturing Technology to Sangamo pursuant to Section 6.3(c), including a description of such Pfizer Manufacturing Technology and any payments that Pfizer would be obligated to pay directly as a result of Pfizer’s grant to Sangamo of the license under Section 2.2(a)(ii), Sangamo’s grant of a sublicense to any of its Affiliates or any Third Party under such license, or the practice of such license or sublicense, as the case may be, by or on behalf of Sangamo, its Affiliates or any of their respective licensees, Sublicensees or contractors. If within [*] days thereafter, Sangamo notifies Pfizer that it does not desire to obtain a sublicense under such Know-How and/or Patent Rights, then such Know-How and Patent Rights will be deemed excluded from the Pfizer Manufacturing Technology. If Sangamo does not notify Pfizer during such [*]-day period that it does not desire such sublicense, then Sangamo shall (i) provide Pfizer, in a timely manner as necessary for Pfizer to comply with its obligations to the Third Party as disclosed to Sangamo, with all information needed in order to determine the requirement to make and the amount of any such payment and (ii)

promptly (but in no event later than [*] days after Pfizer’s submission of an invoice therefor) reimburse Pfizer for the full amount of such payment; provided that at any time Sangamo shall have the right to terminate its sublicense to such Pfizer Manufacturing Technology on [*] written notice to Pfizer, after which the foregoing obligations will terminate with respect to obligations (excluding payments for uncancellable obligations or payments obligations that have been incurred or matured prior to the effective date of termination) accrued under such sublicense after the effective date of termination. Pfizer shall have the right to terminate the sublicense granted to Sangamo with respect to any Pfizer Manufacturing Technology in-licensed from a Third Party in the event Sangamo fails to provide Pfizer any such information or reimburse Pfizer for any such payment(s) required under Pfizer’s agreement with such Third Party and fails to cure such failure within [*] days after written notice thereof from Pfizer specifying the failure.

2.3Reciprocal 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 2.3(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 2.3(b) shall give Pfizer or its Affiliates any right to practice under any Patent Right owned or Controlled by Sangamo or its Affiliates.

2.4No 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 2.4 or Section 4.3(c)) 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.

(a)Exclusivity Obligations. Except for their activities conducted under this Agreement and subject to the exception set forth in Section 2.5(b) below, during the time period [*] (the “Exclusivity Period”), neither Party shall, whether by itself, its Affiliates or with or through any Third Party, conduct any clinical development of, manufacture any clinical or commercial supply of, or commercialize, any [*] (a “Competing Program”).

(b)Exception. Notwithstanding Section 2.5(a), if a Third Party becomes an Affiliate of a Party during the Exclusivity Period 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:

(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 2.5(a), provided that such new Affiliate conducts such Competing Program independently of the activities under this Agreement and does not use any Licensed 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 [*] months 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 [*] month period shall not constitute a breach by such Party of its exclusivity obligations set forth in Section 2.5(a), provided that such new Affiliate conducts such Competing Program during such [*] month period independently of the activities under this Agreement and does not use any Licensed Technology or the Confidential Information of the other Party in the conduct of such Competing Program.

2.6Upstream Licenses. If, during the Term, Sangamo obtains Control of any intellectual property rights (other than the Specified Patents) 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 Product 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). Notwithstanding anything in this Agreement to the contrary, the term and conditions specified in Exhibit G shall apply to the Specified Patents. Each Non-Exclusive Upstream

License for which Pfizer agrees to reimburse Sangamo for payments thereunder pursuant to Section 2.6(a), and each Exclusive Upstream License, will be an “Upstream License”.

(a)Non-Exclusive Upstream Licenses. If within [*] days 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 2.6, 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 [*] days 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 [*] days 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 Section 2.6 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 2.6(a) to make such payments.

2.7Direct 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 2.7 will be borne by Pfizer and reimbursed to Sangamo within [*] days of Sangamo’s invoice therefor.

2.8Right 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 directly relate to any 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). In addition, Pfizer hereby grants to Sangamo, 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 Materials (including the data contained in such Regulatory Materials) submitted by Pfizer, its Affiliates, Sublicensees or their CMOs in connection with the Manufacture of any Product, which right of reference Sangamo may use in connection with its practice of the license granted by Pfizer to Sangamo under Section 2.2(a)(ii) above. Pfizer will provide a signed statement to this effect, if requested by Sangamo, in accordance with 21 C.F.R. § 314.50(g)(3) (or any analogous Law outside of the United States).

(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 2.6 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.

Each Marginal 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 9.5(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 9.5(a) during such Pfizer Year would be calculated as follows:

(b)~~Royalty Term. Pfizer’s royalty payment obligations under Section 9.5(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 Manufacture, approved use, 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) [*] years after the First Commercial Sale of such Product in any 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 9.5(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 9.5(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 9.5(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 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 9.5(d)(vi), Pfizer shall have the right to deduct, from the royalty payment that would otherwise have been due pursuant to Section 9.5(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 9.5(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. 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 and (iii) all obligations, including but not limited to financial obligations, under any agreement between Sangamo and [*], which is identified in Exhibit I, related to [*].

(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 9.5(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 9.5(a) with respect to Net Sales of such Product in such country during such Pfizer Quarter.

(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 [*] days 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 9.5(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 [*] days 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 [*].

9.6Currency; 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 [*] days past such date, interest shall accrue on the sum due from the due date until the date of payment at the rate equal to [*] 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 [*] for the actual number of days payment is delinquent.

9.7Invoicing; 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 [*] days after the Effective Date or within [*] days 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 apinvoices@pfizer.com. Should Pfizer dispute in good faith the nature or basis of any charges contained in any invoice submitted by Sangamo hereunder, Pfizer shall promptly provide written notice to Sangamo setting forth the reason for the dispute, which the Parties shall attempt to resolve in good faith in accordance with Section 16.6. Payment by Pfizer shall not result in a waiver of any of its rights under this Agreement. Each payment hereunder shall be made by electronic transfer in immediately available funds via either back wire transfer, an ACH (automated clearing house) mechanism or any other means of electronic funds transfer, at Pfizer’s election, to the bank account as set forth below or as designated by Sangamo in writing to Pfizer at least [*] days before the payment is due:

Bank Name:	[*]
Beneficiary Account Number:	[*]
Beneficiary Account Name:	Sangamo Therapeutics, Inc.
International SWIFT BIC:	[*]
ABA/Routing Number:	[*]

(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 9.8(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 [*] days 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 16.2), any direction by Pfizer to Sangamo to grant a license or sublicense to any Affiliate of Pfizer pursuant to Section 2.7 (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.

9.9Financial 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 [*] years 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 [*] days after the accountant’s report, plus interest (as set forth in Section 9.6) 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.

9.10Confidentiality. 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 9 will be deemed to be Pfizer’s Confidential Information and subject to the provisions of Article 11.

9.11No Guarantee of Success. Pfizer and Sangamo acknowledge and agree that payments to Sangamo pursuant to Section 9.4(a) and Section 9.5(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.

(a)By Inventorship. Except as set forth in Section 10.1(b) below, ownership of all Inventions shall be based on inventorship, as determined in accordance with the rules of inventorship under United States patent laws. Each Party shall solely own any Inventions made solely by its and its Affiliates’ and Sublicensees’ employees, agents, or independent contractors (“Sole Inventions”). Without limiting the foregoing, Pfizer shall solely own all Pfizer

Manufacturing Improvements, and Sangamo shall solely own all Sangamo Manufacturing Improvements. The Parties shall jointly own any Inventions that are made jointly by employees, agents, or independent contractors of one Party and its Affiliates and Sublicensees together with employees, agents, or independent contractors of the other Party and its Affiliates and Sublicensees (“Joint Inventions”). All Patent Rights claiming patentable Joint Inventions shall be referred to herein as “Joint Patents”. Except to the extent either Party is restricted by the licenses granted to the other Party under this Agreement, each Party shall be entitled to practice, license (through multiple tiers), assign and otherwise exploit the Joint Inventions and Joint Patents in all countries and jurisdictions without the duty of accounting or seeking consent from the other Party.

(b)Improvements to Licensed Technology. Notwithstanding Section 10.1(a), Sangamo shall solely own all Inventions that are improvements to the Licensed Technology (other than Inventions that are improvements to Joint Inventions and Joint Patents but not to any other Licensed Technology), including improvements to [*], but excluding any Inventions that are [*] or that relate to (i) [*] or (ii) [*] that is [*] and that is not [*] or [*]. Upon the JSC’s decision to include an Additional Product as a Product pursuant to Section 4.3(b), the Parties shall determine [*], such that [*]. To the extent any such Invention that belongs to Sangamo under this Section 10.1(b) is made by Pfizer, its Affiliates or Sublicensees or its or their employees, agents, or independent contractors, whether solely or jointly, Pfizer shall and hereby does assign and transfer to Sangamo, without additional consideration, all right, title and interest in and to such Invention, and such Invention shall be deemed Sangamo’s Sole Invention and Sangamo’s Confidential Information (and not the Confidential Information of Pfizer).

(c)Disclosure. Through the JIPC, each Party shall promptly disclose to the other Party all Inventions, including all invention disclosures or other similar documents submitted to such Party by its, or its Affiliates’ or Sublicensees’, employees, agents or independent contractors relating to such Inventions, and shall also respond promptly to reasonable requests from the other Party for additional information relating to such Inventions.

(d)Personnel Obligations. Each employee, agent or independent contractor of a Party or its respective Affiliates or Sublicensees performing work under this Agreement shall, prior to commencing such work, be bound by invention assignment obligations, including: (i) promptly reporting any invention, discovery, process or other intellectual property right; (ii) presently assigning to the applicable Party all of his or her right, title and interest in and to any invention, discovery, process or other intellectual property; (iii) cooperating in the preparation, filing, prosecution, maintenance and enforcement of any patent and patent application; and (iv) performing all acts and signing, executing, acknowledging and delivering any and all documents required for effecting the obligations and purposes of this Agreement. It is understood and agreed that such invention assignment agreement need not reference or be specific to this Agreement.

(i)As between the Parties, Sangamo shall have the sole right, but not the obligation, to file, prosecute and maintain all Licensed Patents that are not Joint Patents (“Sangamo Sole Patents”) throughout the world, at its own expense. Sangamo shall keep Pfizer reasonably informed of the status of such Sangamo Sole Patents and shall promptly provide Pfizer with material correspondence received from any patent authorities in connection therewith. In addition, Sangamo shall promptly provide Pfizer with drafts of all proposed material filings and correspondence to any patent authorities with respect to such Sangamo Sole Patents for Pfizer’s review and comment prior to the submission of such proposed filings and correspondence. Sangamo shall confer with Pfizer and take into consideration Pfizer’s comments prior to submitting such filings and correspondence, provided that Pfizer provides such comments within [*] days of receiving the draft filings and correspondence from Sangamo. If Pfizer does not provide comments within such period of time, then Pfizer shall be deemed to have no comment to such proposed filings or correspondence. In case of a disagreement between the Parties with respect to the filing, prosecution or maintenance of such Sangamo Sole Patents, the final decision shall be made by Sangamo subject to Pfizer’s rights in Section 10.2(a)(ii).

(ii)Sangamo shall notify Pfizer of any decision to cease prosecution and/or maintenance of any Sangamo Sole Patent in any country. Sangamo shall provide such notice at least [*] days prior to any filing or payment due date, or any other due date that requires action in order to avoid loss of rights, in connection with such Sangamo Sole Patent. If, within [*] days after the receipt of such notice from Sangamo, Pfizer notifies Sangamo in writing that it wishes Sangamo to continue the prosecution and maintenance of such Sangamo Sole Patent in such country and agrees to reimburse Sangamo for the costs and expenses that Sangamo incurs in connection therewith, then Sangamo shall continue the prosecution and maintenance of such Sangamo Sole Patent in such country at Pfizer’s cost and expense.

(iii)For the purpose of this Article 10, “prosecution” shall include any post-grant proceeding, including supplemental examination, post grant review proceeding, inter parties review proceeding, patent interference proceeding, opposition proceeding, inter parties review, reissue and reexamination.

(i)As between the Parties, Sangamo shall have the first right, but not the obligation, to file, prosecute and maintain all Joint Patents throughout the world, at its own expense. Sangamo shall keep Pfizer reasonably informed of the status of Joint Patents and shall promptly provide Pfizer with material correspondence received from any patent authorities in connection therewith. In addition, Sangamo shall promptly provide Pfizer with drafts of all proposed material filings and correspondence to any patent authorities with respect to Joint Patents for Pfizer’s review

and comment prior to the submission of such proposed filings and correspondence. Sangamo shall confer with Pfizer and take into consideration Pfizer’s comments prior to submitting such filings and correspondence, provided that Pfizer provides such comments within [*] days of receiving the draft filings and correspondence from Sangamo. If Pfizer does not provide comments within such period of time, then Pfizer shall be deemed to have no comment to such proposed filings or correspondence. Subject to Pfizer’s right to continue prosecution and maintenance of a Joint Patent pursuant to clause (ii) below, in case of a disagreement between the Parties with respect to the filing, prosecution or maintenance of Joint Patents, the final decision shall be made by Sangamo.

(ii)Sangamo shall notify Pfizer of any decision to cease prosecution and/or maintenance of any Joint Patent in any country. Sangamo shall provide such notice at least [*] days prior to any filing or payment due date, or any other due date that requires action in order to avoid loss of rights, in connection with such Joint Patent. In such event, Sangamo shall permit Pfizer, at its discretion and expense, to continue prosecution or maintenance of such Joint Patent in such country. Pfizer’s prosecution or maintenance of such Joint Patent shall not change the Parties’ respective rights and obligations under this Agreement with respect to such Joint Patent other than those expressly set forth in this Section 10.2(b).

(c)Product-Specific Licensed Patents. Sangamo shall use reasonable efforts, in connection with its prosecution of the Sangamo Sole Patents and the Joint Patents, to the extent permitted under applicable Laws, to, reasonably considering comments by Pfizer with respect to such strategy, file patent applications that (i) claim priority to one or more Licensed Patents and (ii) claim one or more Products (generically or specifically) but are not intended to claim any products that are not Products (collectively, the “Product-Specific Licensed Patents”). For clarity, if during prosecution, the claims of a Product-Specific Licensed Patent are amended to include claims that claim any product that is not a Product, then such patent application shall no longer be considered a Product-Specific Licensed Patent.

(d)Other Sangamo Patents. As between the Parties, Sangamo shall have the sole right, but not the obligation, to file, prosecute and maintain throughout the world, at its own expense, all Patent Rights Controlled by Sangamo that are not Licensed Patents or Joint Patents (including Patent Rights claiming Licensed Companion Diagnostic Technology or Sangamo Manufacturing Improvement Technology).

(e)Pfizer Patents. As between the Parties, Pfizer shall have the sole right, but not the obligation, to file, prosecute and maintain all Patent Rights Controlled by Pfizer (including Patent Rights claiming Pfizer Sole Inventions or Pfizer Manufacturing Technology, but excluding Joint Patents) throughout the world, at its own expense.

(f)Cooperation. Each Party shall provide the other Party, at the other Party’s request and expense, all reasonable assistance and cooperation in the patent prosecution efforts under this Section 10.2, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution.

(a)Notification. If either Party becomes aware of any (i) infringement, anywhere in the world, of any issued patent within the Licensed Patents on account of a Third Party’s Manufacture, use, importation, offer for sale or sale of any [*], including any BLA filed by a Third Party for a Biosimilar Product that names a Product as a Reference Product (or similar filing in a country other than the U.S.) or (ii) declaratory judgment action by a Third Party that is developing or commercializing any [*] alleging the invalidity, unenforceability or non-infringement of any of the Licensed Patents (collectively, a “Product Infringement”), such Party will promptly notify the other Party in writing to that effect.

(i)Product-Specific Licensed Patents. For any Product Infringement of a Product-Specific Licensed Patent, as between the Parties, Pfizer shall have the first right, but not the obligation, to bring an appropriate suit or take other action against any person or entity engaged in such Product Infringement, at its own cost and expense. If Pfizer fails to institute and prosecute an action or proceeding to abate such Product Infringement within a period of [*] after the first notice of such Product Infringement under Section 10.3(a) (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 Product-Specific Licensed Patent against such Product Infringement at its own cost and expense.

(ii)Other Licensed Patents. For any Product Infringement of a Licensed Patent that is not a Product-Specific Licensed Patent, as between the Parties, Sangamo shall have the first right, but not the obligation, to bring an appropriate suit or take other action against any person or entity engaged in such Product Infringement, at its own cost and expense. If Sangamo fails to institute and prosecute an action or proceeding to abate such Product Infringement within a period of [*] after the first notice of such Product Infringement under Section 10.3(a) (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 Patent against such Product Infringement at its own cost and expense.

(c)Collaboration. Each Party shall provide to the enforcing Party reasonable assistance in the enforcement action brought under Section 10.3(b), at such enforcing Party’s request and expense, including to be named in such action if required by applicable Laws to pursue such action. The enforcing Party shall keep the other Party regularly informed of the status and progress of such enforcement efforts, shall reasonably consider the other Party’s comments on any such efforts, including, without limitation, determination of litigation strategy, filing of material papers to the competent court. The non-enforcing Party shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall at all times

cooperate fully with the enforcing Party. The enforcing Party shall not settle any claim, suit or action that it brought under Section 10.3(b) in any manner that would negatively impact the applicable Licensed Patents, without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed.

(d)Expenses and Recoveries. The enforcing Party bringing a claim, suit or action under Section 10.3(b) shall be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages in such claim, suit or action, such recovery shall be allocated first to the reimbursement of any expenses incurred by the Party bringing suit, second to the reimbursement of any expenses incurred by the other Party in such litigation, and any remaining amounts shall be [*]; provided, however, that, [*].

(e)Other Infringement. Sangamo shall have the sole right, but not the obligation, to bring and control, at its own cost and expense, any legal action in connection with (i) any infringement of any Licensed Patent that is not a Product Infringement or (ii) any infringement of any Patent Right Controlled by Sangamo that is not a Licensed Patent (including Patent Rights claiming Licensed Companion Diagnostic Technology or Sangamo Manufacturing Improvement Technology).

10.4Patent Extensions. [*] right, but not the obligation, to seek, [*] if so required, patent term extensions, patent term restorations and supplemental protection certificates or the like available under the Law, including 35 USC, Section 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 (a) [*] extend any Licensed Patent [*], including through the use of supplemental protection certificates and the like, [*] and (b) without [*] 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 (i) [*] with respect to such Product and country and (ii) [*], u nless [*].

10.5Patents Licensed From Third Parties. Each Party’s rights under Sections 10.2, 10.3 and 10.4 with respect to any Licensed Patent that is licensed by Sangamo from a Third Party shall be subject to the rights retained by such Third Party.

(a)during the Term and for [*] years thereafter, all Confidential Information of a Party (the “Disclosing Party”) shall be maintained in confidence and otherwise safeguarded by the other Party (the “Receiving Party”) and its Affiliates, in the same manner and with the same protections as the Receiving Party maintains its own confidential information, but in any event no less than reasonable efforts;

(b)the Receiving Party may only use any such Confidential Information for the purposes of performing its obligations or exercising its rights under this Agreement;

(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.

11.2Exceptions. 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:

(a)is known by the Receiving Party at the time of its receipt without an obligation of confidentiality, and not through a prior disclosure by the Disclosing Party, as documented by the Receiving Party’s business records;

(b)is in the public domain before its receipt from the Disclosing Party, or thereafter enters the public domain through no fault of the Receiving Party;

(c)is subsequently disclosed to the Receiving Party by a Third Party who may lawfully do so and is not under an obligation of confidentiality to the Disclosing Party; or

(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.

11.3Authorized Disclosures. Notwithstanding the obligations set forth in Sections 11.1 and 11.6, 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

Before disclosing this Agreement or any of the terms hereof pursuant to this Section 11.4, 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 11.4, 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.

11.5Technical 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. A Party seeking publication shall provide the other Party the opportunity to review and comment on any proposed publication which relates to the Product at least [*] days prior to its intended submission for publication.

In addition, the Party seeking publication shall delay the submission for a period up to [*] days 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 [*] day 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 11.5 after the [*] day 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 11.5 and, except as permitted under Sections 11.2 and 11.3, 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). In the event of any disagreement on publication, the matter shall be referred to the JSC for attempted resolution.

Upon any such termination, the changes to Pfizer’s Diligence Obligations under Sections 8.1(a) and 8.2 will apply as set forth therein, as and to the extent applicable.

(b)Termination for Material Breach. If either Party believes that the other is in breach of its material obligations hereunder, then the non-breaching Party may deliver notice of such breach (“Breach Notice”) to the other Party. If the Party receiving notice of breach fails to cure such material breach within the applicable period set forth below, then the Party originally delivering the notice of breach may terminate this Agreement effective on written notice of termination to the other Party. For all breaches other than a failure to make a payment as set forth in this Agreement, the allegedly breaching Party shall have [*] days from such Breach Notice to cure such breach, provided, however, that if any breach is not reasonably curable within [*] days 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 [*] days. For any breach arising from a failure to make a payment set forth in this Agreement, the cure period will be [*] days 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)Notice. If either Party is seeking indemnification under Section 14.1 or 14.2 (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 [*] Business Days 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 [*] Business Days after notice thereof, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, 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 14.1 or 14.2 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 14.1 or 14.2 upon resolution of the underlying claim.

14.4Mitigation 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 14. 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.

14.5Limitation 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 14.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 14.1 OR 14.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS IN ARTICLE 11.

14.6Insurance. 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 14.1 or Section 14.2, 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 [*] days 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 14. Notwithstanding any provision of this Section 14.6 to the contrary, Pfizer may meet its obligations under this Section

14.6 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 14.

15.1 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.

16.1Force 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.

16.2Assignment. 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 16.3, 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 16.2. 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. The terms and conditions of this Agreement shall be binding upon, and shall inure to the benefit of, the Parties and their respected successors and permitted assigns.

16.3Notification of a Change of Control of Sangamo. Sangamo will notify Pfizer in writing promptly (and in any event prior to the public disclosure thereof) following the entering into of a definitive agreement with respect to a Change of Control of Sangamo.

16.4Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

16.5Notices. All notices which are required or permitted hereunder shall be in writing and sufficient if delivered personally, sent by facsimile (and promptly confirmed by personal delivery, registered or certified mail or overnight courier), sent by nationally-recognized overnight courier or sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

(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.

Sangamo Therapeutics and PFIZER Announce collaboration for hemophilia a gene therapy

Collaboration combines Pfizer’s heritage in Rare Disease, capabilities in gene therapy, and expertise in hemophilia with Sangamo’s deep knowledge in genomic therapies

Richmond, Calif., May 10, 2017 – Sangamo Therapeutics, Inc. (Nasdaq: SGMO) and Pfizer Inc. (NYSE: PFE) today announced an exclusive, global collaboration and license agreement for the development and commercialization of gene therapy programs for Hemophilia A, including SB-525, one of Sangamo’s four lead product candidates, which Sangamo expects will enter the clinic this quarter.

“Sangamo brings deep scientific and technical expertise across multiple genomic platforms, and we look forward to working together to advance this potentially transformative treatment for patients living with Hemophilia A,” said Mikael Dolsten, MD, PhD, President of Worldwide Research and Development at Pfizer. “Pfizer has made significant investments in gene therapy over the last few years and we are building an industry-leading expertise in recombinant adeno-associated virus (rAAV) vector design and manufacturing. We believe SB-525 has the potential to be a best-in-class therapy that may provide patients with stable and durable levels of Factor VIII protein with a single administration treatment.”

“With a long-standing heritage in rare disease, including hemophilia, Pfizer is an ideal partner for our Hemophilia A program,” said Dr. Sandy Macrae, Sangamo’s Chief Executive Officer. “We believe Pfizer’s end-to-end gene therapy capabilities will enable comprehensive development and commercialization of SB-525, which could potentially benefit Hemophilia A patients around the world. This collaboration also marks an important milestone for Sangamo as we continue to make progress in the translation of our ground-breaking research into new genomic therapies to treat serious, genetically tractable diseases.”

Under the terms of the collaboration agreement, Sangamo will receive a $70 million upfront payment from Pfizer. Sangamo will be responsible for conducting the SB-525 Phase 1/2 clinical study and certain manufacturing activities. Pfizer will be operationally and financially responsible for all subsequent research, development, manufacturing and commercialization activities for SB-525 and additional products, if any. Sangamo is eligible to receive potential milestone payments of up to $475 million, including up to $300 million for the development and commercialization of SB-525 and up to $175 million for additional Hemophilia A gene therapy product candidates that may be developed under the collaboration. Sangamo will also receive tiered double-digit royalties on net sales. Additionally, Sangamo will be collaborating with Pfizer on manufacturing and technical operations utilizing viral delivery vectors.

Gene therapy is a potentially transformational technology for patients, focused on highly specialized, one-time, treatments that address the root cause of diseases caused by genetic mutation. The technology involves introducing genetic material into the body to deliver a correct copy of a gene to a patient’s cells to compensate for a defective one. The genetic material can be delivered to the cells by a variety of means, most frequently using a viral vector such as rAAV. There have been no gene therapy products approved in the U.S. to date.

Hemophilia A is a rare blood disorder caused by a genetic mutation resulting in insufficient activity of Factor VIII, a blood clotting protein the body uses to stop bleeding. There are approximately 16,000 patients in the U.S. and more than 150,000 worldwide with Hemophilia A. SB-525 is comprised of a rAAV vector carrying a Factor VIII gene construct driven by a proprietary, synthetic, liver-specific promoter. The U.S. Food and Drug Administration has cleared initiation of human clinical trials for SB-525, which also has been granted orphan drug designation. Sangamo is on track this quarter to start a Phase 1/2 clinical trial to evaluate safety and to measure blood levels of Factor VIII protein and other efficacy endpoints.

Sangamo will host a conference call today, May 10, 2017 at 5:00 p.m. ET, which will be open to the public, to discuss the details of the collaboration and the Company’s first quarter business and financial results. The call will also be webcast live and can be accessed via a link the Sangamo Therapeutics website in the Investors and Media section under Events and Presentations. A replay of the webcast will also be available for one week after the call.

The conference call dial-in numbers are (877) 377-7553 for domestic callers and (678) 894-3968 for international callers. The conference ID number for the call is 15225000.
