(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

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

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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.

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.

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.

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.

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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.

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 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 

  
 22 

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
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

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (c) Notice and Payment. The Party that achieves any milestone event set forth in
Section 5.2(a) or Section 5.2(b) shall notify the other Party in writing within [ * ] after the achievement of any milestone event, and Pfizer shall pay to Sangamo the applicable payment within [ * ] after receipt from Sangamo of a proper
invoice pursuant to Section 5.5 for such milestone event. If Sangamo believes any milestone event has occurred and has not received a written notice of same from Pfizer, it may so notify Pfizer in writing and invoice Pfizer for the
corresponding payment, and in that case shall provide to Pfizer documentation or other information that supports its belief. Any dispute under this Section 5.2(c) that relates to whether or not a milestone event has occurred shall be resolved
in accordance with Section 12.6. 
 5.3 Royalty Payments. 

(a) Royalty Rates. On a Product-by-Product
basis, Pfizer shall pay Sangamo non-refundable, non-creditable royalties based on annual aggregate Net Sales of each Product in the Territory during such Product’s
Royalty Term at the following rates: 
  

			
	 Amount of Aggregate Territory-wide Net Sales
	  	Royalty Rate
	 Net sales up to and including [ * ]
	  	[ * ]%
	 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

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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.

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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 [ * ].

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 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 [ * ]. 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 12.6. 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 [ * ] before the payment is due: 

 

			
	Bank Name:	  	 [ * ]

	Beneficiary Account Number:	  	 [ * ]

	Beneficiary Account Name:	  	 Sangamo Therapeutics, Inc.

	International SWIFT BIC:	  	 [ * ]

	ABA/Routing Number:	  	 [ * ]

 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. 

  
 39 

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
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.

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.

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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
abate 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 

  
 47 

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
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 abate 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 

  
 48 

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
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.

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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. All amounts payable under any such license or agreement with a 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. With respect to any other Infringement Claim (a “Non-Indemnified Infringement Claim”) against Pfizer (including its
Affiliates or Sublicensees) alone, Pfizer will have the right, but not the obligation, to control the defense of such Non-Indemnified Infringement Claim, including control over any related litigation,
settlement, appeal or other disposition arising in connection therewith. Sangamo, upon request of Pfizer, agrees to cooperate with Pfizer at Pfizer’s expense. Sangamo will have the right to consult with Pfizer concerning any Non-Indemnified Infringement Claim. In the case of any Non-Indemnified Infringement Claim against Sangamo alone, Sangamo will have the right, but not the obligation, to
control the defense of such Infringement Claim, including control over any related litigation, settlement, appeal or other disposition arising in connection therewith. Pfizer will have the right to consult with Sangamo concerning such Infringement
Claim and Pfizer, upon request of Sangamo, will reasonably cooperate with Sangamo at Sangamo’s expense. 
 6.5 Patents
Licensed From Third Parties. Each Party’s rights under Sections 6.2 and 6.4 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.

but in any event no less than reasonable efforts; 
 (b) the Receiving Party may only use any such Confidential Information for the

(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,

 (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

 7.4 SEC Filings and Other Disclosures. Either Party may disclose the terms of this
Agreement and make any other public written disclosure regarding the existence of, or performance under, this Agreement, to the extent required, in the reasonable opinion of such Party’s legal counsel, to comply with (a) applicable Law,
including the rules and regulations promulgated by the United States Securities and Exchange Commission or (b) any equivalent Governmental Authority, securities exchange or securities regulator in any country in the Territory. 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. 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 [ * ] prior to its intended submission for publication. The other Party shall provide the Party seeking publication with its comments in
writing, if any, within [ * ] after receipt of such proposed publication. The Party seeking publication shall consider in good faith any comments thereto provided by the other Party and shall comply with the other Party’s request to remove any
and all of such other Party’s Confidential Information from the proposed publication. 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). 
 7.6 Publicity.

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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. 
 (c) The Parties agree that after a press release (including the
initial press release) or other public announcement has been reviewed and approved by the other Party under this Section 7.6, the disclosing Party may reissue the public disclosures without having to obtain the other Party’s prior consent
and approval. 
 (d) Each Party agrees that the other Party shall have the right to use such first Party’s name in
presentations, the company’s website, collateral materials and corporate overviews to describe the collaboration relationship, as well as in taglines of press releases issued pursuant to this Section 7.6. 

(e) Subject to Section 7.6(d), neither Party shall use the name, trade name, service marks, trademarks, trade, dress or logos of
the other Party (or any of its Affiliates) in publicity releases, advertising or any other publication, without the other Party’s prior written consent in each instance. 

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

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
forth in Section 8.2 below (the “Term”). Notwithstanding any provision of this Agreement to the contrary, upon expiration of this Agreement, Pfizer will retain the fully paid-up, perpetual, irrevocable royalty-free license to each Product as set forth in Section 5.3(c), except with respect to those Products and countries for which the Agreement was previously terminated. 

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. 

(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 [ * ] 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

 ARTICLE 10 

INDEMNIFICATION; LIABILITY; INSURANCE 

10.1 Indemnification by Sangamo. Sangamo shall indemnify, defend and hold harmless Pfizer and its Affiliates and Sublicensees,
and each of their respective directors, officers, employees and agents (collectively “Pfizer Indemnitees”), from and against all losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs
(collectively, “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 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. 

  
 64 

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and
Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 (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

 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.

 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

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
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.  
 12.7 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the

 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 Dr. Sandy Macrae, 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 Greg LaRosa, 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

Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended. 

 
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. 
 About Sangamo Therapeutics 

Sangamo Therapeutics, Inc. is focused on translating ground-breaking science into genomic therapies that transform patients’ lives using the
company’s industry leading platform technologies in genome editing, gene therapy, gene regulation and cell therapy. The Company is conducting Phase 1/2 clinical trials in Hemophilia A and Hemophilia B, and in lysosomal storage disorders MPS I
and MPS II. Sangamo has an exclusive, global collaboration and license agreement with Pfizer Inc. for gene therapy programs for Hemophilia A, ALS and FTLD, with Bioverativ Inc. for hemoglobinopathies, including beta thalassemia and sickle cell
disease, and with Shire International GmbH to develop therapeutics for Huntington’s disease. In addition, Sangamo has established strategic partnerships with companies in non-therapeutic applications of
its technology, including Sigma-Aldrich Corporation and Dow AgroSciences. For more information about Sangamo, visit the Company’s website at www.sangamo.com.
