In the event that such average sale price cannot be determined for the stand alone Collaboration ZF Products or the other products, Net Sales for the purposes of determining royalty payments shall be mutually agreed upon by the Parties based on the relative value contributed by each component, such agreement not to be unreasonably withheld, conditioned or delayed.

1.48 “Operational Activities” means (a) participation on working teams with respect to each Research Plan and the Research Committee, (b) review and revision of any and all Research Plans (including any amendments thereto), (c) review and commentary on specific protocols and experimental design, (d) preparation and review of all Interim Research Reports and Final Research Reports, (e) technology transfer to Shire, (f) regulatory support and coordination, and (g) teleconferences and email correspondence with Shire personnel related to the activities set forth in clauses (a) through (f) (to the extent applicable) or responsive to Shire inquiries.

2.2 Factor VIII and Factor IX Program Return. By amending and restating the Original Agreement as this Agreement, Shire is returning to Sangamo Shire’s rights under the Original Agreement with respect to the Sangamo Targets and Sangamo Programs and retaining certain rights with respect to the Shire Targets and the Shire Programs. It is agreed by the Parties that each Party shall have autonomy to develop its own specific programs (i.e., the Shire Programs in the case of Shire and the Sangamo Programs in the case of Sangamo) and for Sangamo to provide research and development support to Shire through the Services and the Operational Activities on a fee-for-service basis as set forth in Section 3.3. Specifically, Shire will control and develop the program directed at the Initial Target and one other program directed at the Additional Target to be designated by Shire in accordance with Section 2.4, and Sangamo will control and develop those programs directed at the Sangamo Targets. The programs directed at these four Targets will be the only programs to which this Agreement pertains. Accordingly, as of the Amendment Effective Date:

(i) The Parties stipulate and agree that Shire will have no obligation to reimburse Sangamo with respect to any costs relating to the Factor VII or Factor X gene Targets.

(ii) Schedule 2.2(a) sets forth all outstanding internal and external costs incurred by Sangamo under the Original Agreement that are to be reimbursed by Shire under the Original Agreement in connection with programs directed at the Factor VIII and Factor IX genes as of the Amendment Effective Date. Within [***] of the Amendment Effective Date, Sangamo will invoice Shire for all amounts set forth on Schedule 2.2(a); provided that with respect to those external costs that are identified in Schedule 2.2(a) as estimated amounts and that have not been invoiced to Sangamo by the applicable Third Party as of the Amendment Effective Date, such invoice will include the applicable estimated amount set forth on Schedule 2.2(a). Shire will not be obligated to reimburse Sangamo for any internal or external cost identified on Schedule 2.2(a) that is not invoiced to Shire on or prior to [***] following the Amendment Date.

(iii) Except for any good faith disputes promptly brought to Sangamo’s attention and for which Shire is diligently seeking resolution, Shire shall pay invoices properly submitted by Sangamo under Section 2.2(a)(ii) within 30 days of the date of receipt of the invoice. With respect to any amounts disputed in good faith by Shire pursuant to the preceding sentence, Shire shall pay all such amounts determined or agreed to be due to Sangamo within 30 days of the date of the resolution of such dispute.

(iv) Shire shall have no further responsibility to reimburse Sangamo, and Sangamo hereby releases Shire and its Affiliates from any obligation to reimburse Sangamo, for any costs or expenses incurred under the Original Agreement, other than (A) those undisputed amounts (or previously disputed amounts that have been determined from a previous resolution or otherwise agreed by the Parties to be due to Sangamo) properly invoiced by Sangamo pursuant to Section 2.2(a)(ii) and (B) those costs and expenses incurred as of the Amendment Effective Date in connection with the program directed at the Initial Target, which Sangamo will invoice and Shire will pay in accordance with the Original Agreement. For clarity, Sangamo will invoice, and Shire will pay, all agreed costs associated with the provision of the Services in accordance with this Agreement.

(b) Assumption of Obligations. Subject to Sangamo’s entry into a master services agreement with [***] as described below, Shire shall assign to Sangamo, and Sangamo shall assume, Shire’s rights and obligations under the statements of work identified on Schedule 2.2(b) (the “SOWs”), which relate solely to the Sangamo Programs. Promptly after the execution of this Agreement, Shire shall put on hold all work under the SOWs, and Sangamo shall initiate negotiations with [***] regarding the terms of a master services agreement between [***] and Sangamo (the “Sangamo MSA”). Unless the Parties otherwise agree in writing

(which agreement may pertain to reserving a slot for [***] to perform work after execution of the Sangamo MSA), all work under the SOWs shall remain on hold until Sangamo notifies Shire that Sangamo and [***] have entered into the Sangamo MSA. Upon such notice, Shire shall notify [***] that the SOWs are no longer subject to the Master Services Agreement between Shire and [***] dated [***] but are instead governed by the Sangamo MSA, and [***] should follow Sangamo’s instructions with respect thereto. If Sangamo and [***] have not entered into the Sangamo MSA within [***] after the Amendment Effective Date (or such longer period as the Parties agree upon in writing), then for each SOW Sangamo shall either (a) instruct Shire to have the SOW performed on Sangamo’s behalf and reimburse Shire for all amounts owed to [***] under such SOW on account of such performance or (b) instruct Shire to terminate such SOW and reimburse Shire for any termination fees owed to [***] on account of such termination.

(c) Transition Period. For a period of not more than [***] (the “Transition Period”), at Sangamo’s request, Shire will provide Sangamo with reasonable assistance as necessary to effect the timely and orderly transfer of the Sangamo Programs to Sangamo by performing those activities related to the Sangamo Programs attached hereto as Schedule 2.2(c) (the “Transition Activities”). For clarity, Sangamo’s requests will specify which Transition Activities it would like Shire to perform, Sangamo may make multiple requests during the Transition Period, and Sangamo’s later requests may pertain to Transition Activities that were not the subject of its earlier requests. Sangamo shall pay all Shire FTE costs at the FTE Rate and external costs reasonably incurred by Shire and its Affiliates in the conduct of the Transition Activities in response to Sangamo’s requests, up to a maximum total amount of [***]. If Sangamo requests that Shire or its Affiliates incur any Shire FTE costs or external costs in the conduct of the Transition Activities that will exceed such maximum total amount specified for performance of the Transition Activities, then, following Sangamo’s agreement in writing to pay for up to a specified amount of additional Shire FTE time or additional external costs (notwithstanding such maximum total amount), Shire will invoice Sangamo for all Shire FTE costs (at the FTE Rate) and external costs reasonably incurred by Shire and its Affiliates in connection with such additional Transition Activities that exceed such maximum total amount but do not exceed such specified amount. For further clarity, after such maximum total amount has been met, Shire shall not be obligated to devote Shire FTE time or incur external costs that exceed the specified amount agreed by Sangamo in advance in writing. Shire shall accrue and report its actual costs quarterly during the Transition Period. Shire shall provide an invoice within five business days of the end of each quarter, with sufficient detail reasonably acceptable to Sangamo (including all statement, receipts or vouchers documenting any external costs), for the activities performed during such quarter and external costs invoiced to Shire during such quarter. Subject to any good faith disputes promptly brought to Shire’s attention and for which Sangamo is diligently seeking resolution, Sangamo shall pay such invoices within [***] of the date of receipt of the invoice to the extent that (i) such invoices do not collectively exceed the maximum total amount stated above, or (ii) if such invoices do exceed such maximum total amount, Sangamo has agreed with respect to such excess amounts in accordance with this Section 2.2(c). With respect to any amounts disputed in good faith pursuant to the preceding sentence, Sangamo shall pay all such amounts determined or agreed to be due to Shire within [***] of the date of the resolution of such dispute.

(d) Release. Sangamo, on behalf of itself and each of its Affiliates and each of their respective successors and assigns (collectively, the “Releasors”), do hereby now and forever release, remise, hold harmless and forever discharge Shire, its Affiliates, their employees, agents and representatives and each of their respective successors and assigns (collectively, the “Releasees”) of and from all debts, demands, actions, causes of action, suits, accounts, covenants, contracts, agreements, claims, rights, damages, losses or liabilities of any nature, character, or kind whatsoever, both at law or in equity, (each a “Claim”) whether known or unknown, suspected or unsuspected, and which arose at any time on or prior to the Amendment Effective Date, or that thereafter could arise based on any act, fact, transaction, matter or cause which occurred on or prior to the Amendment Effective Date arising from, or relating to, the research, development, manufacturing or commercialization of the Sangamo Safe Harbor ZF Compounds or the Sangamo ZF Products, but excluding any Claims arising from or related to the gross negligence or willful misconduct of any Releasees or Shire’s breach of the Original Agreement other than its breach of Section 3.2 and Section 5.1 of the Original Agreement (collectively, the “Released Claims”). The Releasors further agree that they will (i) forbear from exercising any rights or remedies against any Releasee in respect of any or all Released Claims and (ii) not commence any lawsuit or bring any legal or equitable action against any Releasee in respect of any Released Claims. Each Releasee will be an express beneficiary of the rights and releases granted under this Section 2.2(d) and will be entitled to rely on the same as a defense to any suit brought against such Releasee in contravention of the provisions of this paragraph.

2.3 Collaboration. Sangamo shall conduct certain activities to identify and preclinically develop Shire ZF Products for Shire to advance through human clinical trials and bring to patients as commercial therapeutics and diagnostics in the applicable Fields, by performing the activities of the Research Program, which activities are outlined in Article 3. The Research Program will focus on Shire Targets. This Agreement will be a joint research agreement under 35 U.S.C. § 103(c)(3) entered into for the purpose of researching, identifying and developing Collaboration ZF Products. For the avoidance of doubt, the Research Program will continue during the Research Term until the completion of all activities under the Research Plans, unless the Agreement is terminated in its entirety as provided in Article 15.

2.4 Shire Target Selection. Shire shall have the right to designate one additional Target (the “Additional Target”) for inclusion as a Shire Target according to the procedure set forth in Section 2.4(a) through Section 2.4(e), to the extent that such Target is not a Section 2.4 Rejected Target and is not a gene that is related to the cause or treatment of any of the following: [***]; provided that if Shire fails to designate the Additional Target by [***] (or [***] if such Additional Target is a Reserve Target), then Shire shall have no further rights to designate the Additional Target, unless Shire’s failure to designate the Additional Target by such date results from Sangamo’s failure to perform any of its obligations hereunder. Shire may propose up to three proposed Additional Targets that are not Reserve Targets at a given time for inclusion as the Additional Target according to the procedure set forth in Section 2.4(a) through Section 2.4(e) (but Shire may designate only one Target as the Additional Target).

(a) Notice to Sangamo. Shire shall provide notice to Sangamo of its proposed Additional Targets and shall include in such notice (i) the nucleic acid sequence and locus identification number of the wild-type allele (as obtained from a mutually agreed publicly available database), (ii) the cell(s) in which the protein encoded by each such proposed Additional Target is normally expressed, (iii) whether the product or therapy of interest to Shire for each such proposed Additional Target would be designed to delete, inactivate, repair, modulate the expression of or insert a functional version of such proposed Additional Target; provided that in no event will Shire have the right to propose or designate an Additional Target for which the product or therapy of interest would be [***], (iv) if such proposed Additional Target is not a Reserve Target, whether Shire intends to develop Shire ZF Products [***] and (v) [***] (collectively, the “Additional Target Notice”). If Shire designates as the Additional Target a proposed Additional Target that is not a Reserve Target, then [***]. For clarity, subject to Section 5.5(c), nothing herein will restrict Shire’s ability to freely develop and commercialize Shire ZF Products directed to [***].

(i) Reserve Targets. Sangamo shall conduct initial in silico feasibility studies for all Reserve Targets prior to [***]. Following completion of the in silico feasibility study for the Reserve Targets, the Parties will discuss the results of such studies and potential approaches to address any issues or concerns arising from such studies.

(ii) Other Proposed Additional Targets. For each proposed Additional Target that is not a Reserve Target, within [***] (or sooner if practicable) of receipt by Sangamo of the applicable Additional Target Notice, Sangamo shall notify Shire whether the proposed Additional Target is an Excluded Target. Following such notification, Sangamo shall conduct initial in silico feasibility studies for up to [***] proposed Additional Targets that are not Reserve Targets (and not Excluded Targets) at any given time. Following completion of the in silico feasibility study for each proposed Additional Target that is not a Reserve Target, the Parties will discuss the results of such study and potential approaches to address any issues or concerns arising from such study.

(iii) Feasibility Notice. Prior to [***] with respect to the Reserve Targets, and no later than [***] following Sangamo’s receipt of the Additional Target Notice for each proposed Additional Target that is not a Reserved Target, Sangamo shall notify Shire in writing (the “Feasibility Notice”) whether or not each Reserve Target or each other proposed Additional Target, as applicable: (A) is not a technically viable candidate for developing ZF Compounds that Specifically Bind such proposed Additional Target for the type of product or therapy identified pursuant to Section 2.4(a)(iii), or (B) is subject to any other substantial, bona fide concern known to Sangamo with respect to developing a Shire ZF Product for such Reserve Target or other proposed Additional Target (as applicable). Such notification under Section 2.4(b)(iii)(A) or Section 2.4(b)(iii)(B) shall include an explanation of the reasons, containing an appropriate level of scientific and technical detail, why the Target is not a technically viable candidate or Sangamo’s other substantial and reasonable bona fide concern.

(iv) Designation as Additional Target. Notwithstanding anything to the contrary herein, Shire may in its sole discretion designate a proposed Additional Target as the Additional Target notwithstanding Sangamo’s determination that such in silico feasibility studies demonstrate that such proposed Additional Target is not a technically viable candidate or is subject to any other substantial, bona fide concerns, unless any such concern is a substantial, bona fide and reasonable safety concern, in which case the proposed Additional Target will be a Section 2.4 Rejected Target and Shire will not have the right to designate such proposed Additional Target as a Shire Target.

(v) Costs. Sangamo shall provide to Shire an estimate of all FTE costs (at the FTE Rate) and external costs to be reasonably incurred by Sangamo in connection with conducting its activities under this Section 2.4(b) and Section 2.4(d), and following Shire’s written approval of such proposed budget, Shire shall reimburse Sangamo for all costs included in such approved budget properly invoiced by Sangamo in accordance with Section 3.3(g); provided that such costs do not exceed [***] of such budget approved by Shire; and provided further that Sangamo shall not be obligated to conduct any activities under Section 2.4(b) or Section 2.4(d) that are not reimbursed by Shire.

(c) Rejected Targets. If Sangamo notifies Shire that a proposed Additional Target is rejected because the proposed Additional Target is (i) an Excluded Target or (ii) subject to substantial, bona fide safety concerns as articulated in the Feasibility Notice under Section 2.4(b)(iii) or (iii) subject to the technical viability issues or any other (non-safety-related) concerns articulated in the Feasibility Notice under Section 2.4(b)(iii), and Shire does not notify Sangamo within [***] of Shire’s receipt of the Feasibility Notice that Shire is exercising its right pursuant to Section 2.4(b)(iv) to proceed with such proposed Additional Target nevertheless (each such rejected Target under (i), (ii) or (iii), a “Section 2.4 Rejected Target”), then such Section 2.4 Rejected Target shall not be included as a Shire Target.

(d) Target Assessment. If such proposed Additional Target is not a Section 2.4 Rejected Target or a Reserve Target, then Shire shall have [***] from receipt of the Feasibility Notice from Sangamo to conduct a review and evaluation of all relevant intellectual property relating to such proposed Additional Target and the Parties shall discuss the same; provided that Shire shall be solely responsible for all intellectual property assessments concerning such proposed Additional Target. With respect to all Reserve Targets, Shire may conduct its review and evaluation of all relevant intellectual property relating to such proposed Reserve Target at any time, so long as its assessment is complete sufficiently in advance to permit Shire to designate such Reserve Target as the Additional Target prior [***].

(e) Target Designation. Prior to the end of the review period set forth in Section 2.4(d), Shire shall, in its sole discretion, determine whether to designate a proposed Additional Target as the Additional Target, and shall notify Sangamo of such determination. If Shire does not elect under this Section 2.4(e) to designate a proposed Additional Target as the Additional Target by the end of the applicable review period set forth in Section 2.4(d), such proposed Additional Target shall not be the Additional Target and neither Party shall have any rights or obligations to the other Party hereunder in respect of such proposed Additional Target, except as required pursuant to Article 12. If Shire does elect under this Section 2.4(e) to designate a proposed Additional Target as the Additional Target and it has not designated any other proposed Additional Target as the Additional Target, then such proposed Additional Target shall become the Additional Target and the Parties shall not have any further obligations under Section 2.4 (other than Shire’s obligation to reimburse Sangamo pursuant to Section 2.4(b)(v)). If Shire does not designate any proposed Additional Target as the Additional Target and it has not designated any other proposed Additional Target as the Additional Target, then the Parties will repeat the process under this Section 2.4, to the extent applicable, provided that if Shire desires to propose a potential Additional Target that is not a Reserve Target, Shire shall provide a new proposed Additional Target no later than [***] after (i) the date on which the most recently proposed Additional Target becomes a Section 2.4 Rejected Target or (ii) if such Target is not a Section 2.4 Rejected Target, the end of the [***] review period in Section 2.4(d), as applicable; provided that, subject to the proviso in the first sentence of the first paragraph of Section 2.4, Shire shall not have the right to propose or designate an Additional Target that is not a Reserve Target after [***], and Shire shall not have the right to propose or designate an Additional Target that is a Reserve Target after [***]. Shire shall not have the right to replace a Shire Target or to designate more than one Additional Target.

(f) No Encumbrance of Reserve Targets. Sangamo shall ensure that at all times prior to the earlier of [***] or the date of Shire’s designation of the Additional Target, (i) clauses (b) and (c) of the definition of Excluded Target do not apply to any Reserve Target and (ii) the nucleic acid sequence of the allele to be targeted by Sangamo or a Third Party licensee with respect to a Target described in clauses (b) and (c) of the definition of Excluded Target is not a [***] of a Reserve Target. For the avoidance of doubt, the [***] for each Reserve Target are identified on Schedule 1.65.

3.1 Sangamo Responsibilities. Subject to the terms of this Agreement, Sangamo shall be solely responsible for the management and direction of the Sangamo Programs in its sole discretion and at its sole cost and expense.

3.2 Shire Responsibilities. Subject to the terms of this Agreement, Shire shall be solely responsible for the management and direction of the Shire Programs in its sole discretion and at its sole cost and expense. Without limitation, Shire shall be responsible for oversight of the Research Program during the Research Term and Development Plans, including activities conducted pursuant to the Research Plans, Development Plans, preclinical work, and IND/CTA submissions for each Shire Target.

3.3 Research and Development Services. Shire may, in its sole discretion, engage Sangamo to provide certain (i) research and development services with respect to a Shire Target to identify or support the preclinical development of Development Candidates, to the extent that such services are described on Schedule 3.3 (together with the Exclusive Services, the “Services”), and (ii) Operational Activities, which Services and Operational Activities will be described in one or more Research Plans executed by the Parties, and Sangamo hereby agrees to provide such Services and Operational Activities to Shire.

(a) Exclusive Services. Solely with respect to the Exclusive Services (and no other Services), Shire shall engage only Sangamo (and no other Third Party) under this Article 3 to conduct the Exclusive Services for the Additional Target.

(b) Non-Exclusive Services. Nothing herein will prevent Shire from performing, or having performed on its behalf by any Third Party, any service described on Schedule 3.3 (other than Exclusive Services), including [***] of Shire ZF Products prior to Development Candidate Selection. If Shire wishes to conduct (or have conducted) such [***], then Sangamo shall disclose [***] to Shire or its designee solely to the extent [***] that will include [***] provided, however, that Sangamo’s agreement to such [***]. In any event, however, Shire will not have access to (nor will Shire reverse engineer or have reverse engineered) [***], whether such [***] is conducted by Shire or by a Third Party, and Shire will only receive access after [***]. Instead, prior to such [***], Sangamo will serve as the intermediary to the degree that [***] are to be transferred to any Third Party engaged by Shire to perform such [***]; provided, however, that Sangamo will not be obligated to serve as such an intermediary unless such Third Party enters into a confidentiality agreement with Sangamo that reasonably restricts such Third Party’s disclosure and use [***]. Shire shall and hereby does, or shall cause the applicable Third Party to, [***]; provided that Shire shall [***] in the course of [***].

(c) Performance of the Exclusive Services [***]. If Sangamo materially breaches its obligation to provide the Exclusive Services in accordance with the terms of this Agreement or as set forth in a Research Plan and fails to cure such breach within [***] days of receiving written notice thereof from Shire, then, at Shire’s election (A) Shire may immediately terminate this Agreement in accordance with Section 15.2; provided that no additional cure period will be afforded to Sangamo or (B) in lieu of termination of this Agreement, Shire may cause the following to apply by providing written notice to Sangamo, in which case the following will be Shire’s sole remedy for such material breach:

(i) the exclusivity restrictions set forth in Section 3.3(a) will not apply to the applicable Exclusive Services and [***];

(ii) Sangamo shall disclose [***] that is required to enable the performance of such Exclusive Services [***], in accordance with a procedure to be mutually agreed by the Parties that will include reasonable safeguards to protect the confidentiality of Sangamo’s trade secrets; provided that agreement to such procedure by Sangamo shall not be unreasonably withheld, conditioned or delayed; and

(iii) Sangamo shall reimburse Shire for the external costs to be incurred by Shire in connection with having [***] perform such Exclusive Services.

(d) Research Plan Content. All research and development Services and Operational Activities to be performed with respect to each Shire Target shall be set forth in one or more separate Research Plans developed by Shire and mutually agreed by the Parties; provided that agreement to the Research Plan by Sangamo shall not be unreasonably withheld, conditioned or delayed. The objective of all Services performed under each Research Plan with respect to each Shire Target will be to achieve Development Candidate Selection for at least one Shire ZF Product for such Shire Target and to perform any other additional research and development activities mutually agreed to by the Parties following such Development Candidate Selection; provided that in no event will Sangamo be obligated to conduct any activities required for Development Candidate Selection that are not described on Schedule 3.3 unless otherwise agreed by Sangamo in a Research Plan executed by the Parties. Each Research Plan will contain (i) a work plan and timeline, (ii) a description of the specific activities to be performed by Sangamo, including all Operational Activities, and the planned monthly FTE usage and maximum total number of hours that Sangamo is obligated to spend on each such Operational Activity, and (iii) an estimate, to be proposed by Sangamo and mutually agreed to by the Parties in advance of execution of the applicable Research Plan, of the FTE costs (at the FTE Rate) and the external costs to be incurred by Sangamo in the performance of the Services and Operational Activities to be provided pursuant to such Research Plan (for each Research Plan, the “Budget”). In addition, each Research Plan shall identify a Sangamo project leader, reasonably acceptable to Shire, which project leader shall devote no less than [***] of his or her time to carrying out the Research Plan during the active conduct of such Research Plan prior to Development Candidate Selection thereunder, and will participate in the working team in accordance with Section 3.4(a). Each Research Plan shall be consistent with the terms of this Agreement and shall be appended to and form a part of this Agreement. Upon execution of a Research Plan by both Parties, such Research Plan shall become effective as of the date so indicated. Sangamo shall perform the Services consistent with this Agreement and the applicable Research Plan. In the event of an inconsistency between a Research Plan and this Agreement, the terms of this Agreement will prevail except to the extent the Research Plan expressly provides that it is intended to override this Agreement. The initial Research Plan for the Initial Target as of the Amendment Effective Date, which may be subsequently modified by the Parties in accordance with Section 3.3(e), is set forth in Schedule 3.3(d).

(i) Each Research Plan shall be reviewed and updated as necessary, but at least [***], by Shire, subject to Sangamo’s approval as described below. Sangamo will have the right to review and comment on each Research Plan, and all updates thereto. Changes to the Services (including the scope or timeline thereof) included in a Research Plan, or any Budget therein, or the provision of any service or activity by Sangamo not set forth in a Research Plan, may in each case only be made by mutual agreement of the Parties in writing; provided that if Shire requests that Sangamo perform additional [***] services within [***] months after the delivery of the Final Research Report pursuant to Section 3.4(d) to [***] pursuant to the Research Program that have [***], then Sangamo will perform such services upon Shire’s request (and such services will be “Services” for the purposes of this Agreement regardless of whether they are identified in a Research Plan) and Shire will reimburse Sangamo for its FTE costs (at the FTE Rate) and external costs incurred in the course of performing such screening services.

(ii) If Shire wishes to change or terminate the scope of the Services included in a Research Plan, then Shire shall so advise Sangamo and shall submit a proposed amendment with detailed specifications to Sangamo. Upon receiving such proposed amendment, Sangamo shall provide Shire with its written estimate of the FTE costs (at the FTE Rate) and external costs associated with performing the changed or additional services, and such additional costs will be included in the applicable Budget. In addition, if Sangamo reasonably anticipates that the costs of conducting, or having a Subcontractor conduct, any activity set forth in a Research Plan will exceed the amount set forth in the then-current Budget therefor, Sangamo may notify Shire and request a change to the Budget. Such notification shall include a Sangamo proposed budget change, which shall identify the activity and cost differences from the existing Budget. The Parties shall in good faith discuss all such changes to the Services requested by Shire or changes to any Budget proposed by Sangamo and will use good faith efforts to agree to any such changes within [***] of a Party’s request therefor. If

the Parties are unable to agree on the specific terms of any such amendment, no changes shall be made. Further, if (i) the Parties are unable to agree with respect to the terms of any amendment to the Services or the provision by Sangamo of any new service or activity not set forth in the Research Plan, or (ii) Shire does not agree to any Budget change requested by Sangamo for any activity set forth in a Research Plan, then in each case Sangamo shall not be obligated to conduct, or cause any Subcontractor to conduct, any such activity that will not be fully reimbursed by Shire, and Shire shall have the right to perform such activity itself or freely subcontract such activity to any Third Party; provided, however, if failure to agree relates to any Exclusive Service, then Shire may [***] and (A) the exclusivity restrictions set forth in Section 3.3(a) will not apply to Shire’s subcontracting of such activity [***] and (B) the terms of Section 3.3(c)(i) and Section 3.3(c)(ii) will apply.

(f) Budgeted Costs. Shire shall pay the Sangamo FTE costs (at the FTE Rate) and external costs incurred by Sangamo and its Affiliates in the conduct of Services in accordance with the Budget set forth in the applicable Research Plan. The FTE costs will be calculated using the FTE Rate and the number of FTEs will be calculated based on the average of the applicable percentage of weekly time attributable to the Research Program for each FTE, based on a [***] hour week, up to a maximum of [***] hours per week for each FTE. For the avoidance of doubt, external costs will be passed through to Shire with no mark-up by Sangamo. Following approval of a Budget variances from such Budget [***] shall be paid by Sangamo in accordance with Section 3.3(e), unless otherwise agreed to by Shire, other than with respect to amounts incurred by Sangamo for time spent for a particular Operational Activity in excess of the amount of time set forth in the Research Plan for such activity. Solely with respect to the Operational Activities, any assistance by Sangamo to Shire or communications between Sangamo and Shire that exceed the number of hours allocated to the applicable Operational Activity in the Research Plan will not be within the scope of the Research Plan or Budget. Instead, following Shire’s request that Sangamo conduct the applicable Operational Activity and Shire’s agreement with respect to such time in excess of the applicable maximum number of hours with respect to such applicable Operational Activity, Sangamo will invoice Shire for all Sangamo FTE costs (at the FTE Rate) and external costs reasonably incurred by Sangamo and its Affiliates in connection with such additional activities in accordance with Section 3.3(g).

(g) Invoices. Sangamo shall accrue its actual costs quarterly. Sangamo shall provide an invoice of such actual costs within [***] days of the end of each quarter, with sufficient detail reasonably acceptable to Shire (including all statement, receipts or vouchers documenting any external costs), for the activities performed during such quarter and external costs invoiced to Sangamo during such quarter. For activities set forth in the Research Plan (other than the Operational Activities), the actual number of FTEs or external costs reported in the invoice may not [***] of the expected number based on each Budget for each Research Plan; provided that the actual number is consistent with, and not more than [***], the overall Budget for a particular Research Plan. Shire shall have no obligation to pay Sangamo any amount that (i) is more than [***] the Budget for any Research Plan in any quarter, or (ii) exceeds [***] the overall Budget under a Research Plan most recently agreed by the Parties. Activities requested by Shire to be performed by Sangamo and not set forth in the Research Plan, and Operational Activities (to the extent that Sangamo expends more time than specified for such activity in the applicable Research Plan) are not subject to the preceding sentence. On a monthly basis, with respect to each Operational Activity set forth in each Research Plan, Sangamo shall provide written notice to Shire summarizing (i) a good faith estimate of the number of hours Sangamo has then spent toward such Operational Activity in such month and (ii) the number of hours forecasted to be spent by Sangamo on such Operational Activity in the upcoming month; provided, however, that the numbers of hours set forth in such monthly notices shall not be binding upon either Party and shall not limit or reduce the amounts that Shire would otherwise be obligated to pay pursuant to this Section 3.3. For clarity, and notwithstanding anything to the contrary set forth herein, Shire will not be required to reimburse Sangamo for any time spent on Operational Activities in excess of the maximum number of hours set forth in the applicable Research Plan unless Shire has agreed in advance in writing with respect to such excess time. For further clarity, Sangamo shall not be obligated to spend more time on any Operational Activity than the excess time agreed by Shire in advance in writing.

(h) Ongoing Knowledge Transfer. In the course of performing Services, Sangamo will transfer to Shire all Sangamo Know-How (i) developed under the Services or (ii) reasonably requested by Shire and not previously provided to Shire, in each case by providing copies of requested documentation, materials and other embodiments of such technology, and by making available its qualified technical personnel as set forth under the applicable Research Plan to consult with Shire with respect to such technology or as otherwise reasonably requested by Shire. If the amount of time requested by Shire with respect to such technical assistance exceeds the maximum number of hours Sangamo is obligated to spend on such activity under the applicable Research Plan, then Shire shall reimburse Sangamo’s FTE costs (at the FTE Rate) and external costs of such technical assistance (with no mark-up thereon). Except as provided under Section 3.3(c)(ii), Sangamo shall have no obligation to transfer Know-How relating to the provision of the Exclusive Services.

(i) Quality and Timeliness. Sangamo shall perform the Services using at least the same degree of care and effort that it uses to perform similar services on its own behalf for its own programs, and using qualified personnel with sufficient skill and experience and will use Commercially Reasonable Efforts to perform the Services in compliance with the timelines and work plan set forth in the Research Plan.

(a) Working Teams. The Parties will form a working team for each Research Plan comprising at least the project leader for the Research Plan (who will be a Shire employee) and the Sangamo team leader (who will be a Sangamo employee) and one or more representatives from each of Shire and Sangamo, which team will stay in active communication about activities taking place and Results arising under the respective Research Plan. This team shall confer regularly to ensure close cooperation and exchange of information between the Parties as Sangamo fulfills its responsibilities under the Research Program. The working teams will not have decision making authority, but will facilitate the day-to-day implementation of the Research Plans. If the amount of time requested by Shire with respect to such participation on the working teams exceeds the maximum number of hours Sangamo is obligated to spend on such activity under the applicable Research Plan, then Shire shall reimburse Sangamo’s FTE costs (at the FTE Rate) and external costs of such participation (with no mark-up thereon).

(b) Materials Transfer. To facilitate the conduct of the Research Program or a Development Plan, or otherwise pursuant to Section 5.4(d), either Party may provide to the other Party certain biological materials or chemical compounds owned by or licensed to the supplying Party for use by the other Party (such materials or compounds and any progeny and derivatives thereof, collectively, “Materials”). All such Materials shall remain the sole property of the supplying Party, shall be used only in the fulfillment of obligations or exercise of rights under this Agreement and solely under the control of the receiving Party, shall not be used or delivered to or for the benefit of any Third Party without the prior written consent of the supplying Party, and shall not be used in research or testing involving human subjects, unless expressly agreed. The Materials supplied under this Section 3.4(b) are supplied “as is” and must be used with prudence and appropriate caution in any experimental work, since not all of their characteristics may be known.

(c) Interim Research Reports. During the Research Term, if Shire would like a report summarizing the Services performed by Sangamo under the Research Plans over any time period (each, an “Interim Research Report”) Sangamo will provide any and all necessary or useful Results, information, raw data, data sets, protocols and analysis performed under the Services to enable Shire to prepare a draft of such report for Sangamo’s review and revision. Sangamo shall review and revise each such draft Interim Research Report in accordance with the applicable amount of time set forth under the applicable Research Plan.

(d) Final Research Report. With respect to the Research Program for each Shire Target, no later than [***] days after completion of Sangamo’s Services and all Operational Activities contemplated at such time under such Research Program in accordance with the Research Plan, Sangamo shall prepare and submit to Shire a final written report summarizing all activities undertaken and all accomplishments achieved in connection with such Research Program in a format set forth in the Research Plan (each, a “Final Research Report”). Each Final Research Report shall contain a complete and accurate description of the results and conclusions of the Services under the applicable Research Plan, including (i) a list of all [***] set forth in the applicable Research Plan or any amendment thereto, including [***] that have [***] with more than [***], (iii) a summary of all [***] under such Research Program, in hard copy and electronic format, including relevant [***], (iv) [***] and (v) written updates to Schedule 1.74 as necessary based on applicable [***] or [***]. The contents of each Interim Research Report and Final Research Report shall be considered Confidential Information of both Parties until Development Candidate Selection by Shire, and will be considered Confidential Information of Shire following such Development Candidate Selection by Shire, and in each case shall be subject to the rights and obligations of the Parties under Article 12. If the amount of time requested by Shire with respect to assistance and preparation of the Interim Research Reports and Final Research Reports exceeds maximum number of hours Sangamo is obligated to spend on such activity under the applicable Research Plan, then Shire shall reimburse Sangamo’s FTE costs (at the FTE Rate) and external costs of such assistance (with no mark-up thereon).

3.5 Development Candidate Selection. With respect to each Shire Target, Shire will have the option to designate as Development Candidates one or more [***] of potential Development Candidates in any Interim Research Report or the Final Research Report (“Development Candidate Selection”) in its sole discretion. Shire may make a Development Candidate Selection for a Shire ZF Compound at any time during the Term by delivering a written notice to Sangamo indicating that it elects to designate such Shire ZF Compound as a Development Candidate. Shire will not file an IND/CTA for any [***] that Shire has not designated as a Development Candidate pursuant to this Section 3.5.

3.6 Subcontractors. In performing its activities under any Research Plan and this Agreement, Sangamo may engage any consultant, subcontractor, or other vendor to conduct Sangamo’s obligations under a Research Plan (each, a “Subcontractor”); provided that all such engagements and any contracts related to such engagements are approved in advance by Shire and identified in the applicable Research Plan or an executed amendment thereto. To facilitate approval of all Subcontractors by Shire, Sangamo shall identify each Subcontractor, the activities proposed to be performed by such Subcontractor and the budget for such activities. Shire in its discretion may request a copy of the proposed contract with the Subcontractor prior to approving such contract, and any agreement with a permitted Subcontractor pertaining to the Research Program shall be consistent with the provisions of this Agreement. Without limitation, such contracts entered into with Third Party Subcontractors shall contain provisions, including those relating to intellectual property, confidentiality and non-use, adequate for Shire to enjoy the licenses and assignments granted hereunder as though Sangamo had performed the contracted work itself and that are no less stringent than those set forth in this Agreement. For the avoidance of

doubt, during the period prior to Sangamo’s transfer of information and materials to Shire pursuant to Section 3.3(h) or Section 5.4(b) (as applicable), Sangamo shall, and shall require its Affiliates and any Subcontractor to, maintain such information and materials as required by law in connection with any IND or CTA anticipated to be filed in connection with the applicable ZF Compound or ZF Product. Sangamo shall be responsible for the management of its permitted Subcontractors. The engagement of any Subcontractor in compliance with this Section 3.6 shall not relieve Sangamo of its obligations under this Agreement or any applicable Research Plan.

3.7 Compliance. In performing its activities under any Research Plan and this Agreement, Sangamo will, and will require its Affiliates and any Subcontractor to, comply with all applicable laws, regulations and guidelines concerning such manufacturing and development activities. In no event shall Sangamo conduct, or be obligated to conduct, any activities under a Research Program or otherwise for Shire in compliance with Good Manufacturing Practices or GLP (or similar standards) for the performance of laboratory activities as are required by applicable law.

(a) Research Records Sangamo shall create and maintain, and cause its employees and Subcontractors to maintain, written records and laboratory notebooks of the data and other information generated or recorded in the performance of the Services (collectively, the “Results”) and all such Results shall be Know-How created under the course of the Collaboration and subject to applicable terms of this Agreement. Sangamo will maintain all such Results in sufficient detail and in a good scientific manner appropriate for (i) inclusion in filings with regulatory authorities, and (ii) obtaining and maintaining intellectual property rights and protections, including Patent Rights. Such Results shall be complete and accurate in all material respects and shall fully and properly reflect all work done, data and developments made, and results achieved. Laboratory notebooks shall be signed, dated and witnessed on a regular basis. During the Research Term Sangamo shall periodically, but not less than [***], allow Shire to inspect and, to the extent necessary or useful for such regulatory or intellectual property protection purposes, copy such Results.

(b) Expense Records. Sangamo shall maintain complete and accurate books, records and accounts used for the determination of FTEs and external expenses incurred in connection with the performance of the Services, in sufficient detail to confirm the accuracy of any payments required under this Agreement, which books, records and accounts will be retained by Sangamo for three years after creation of the individual records, or longer as is required by applicable law. Such books, records and accounts shall be kept in accordance with U.S. GAAP and Sangamo’s then-current accounting procedures. For the avoidance of doubt, if Sangamo’s then-current accounting procedures are not U.S. GAAP compliant, then Sangamo shall alter its accounting procedures such that they are U.S. GAAP compliant.

(a) Audit Frequency. Upon [***] advance written notice by Shire and not more than once in each calendar year, Sangamo and its Affiliates shall permit an independent certified public accounting firm of internationally-recognized standing, selected by Shire and reasonably acceptable to Sangamo, at Shire’s expense, to have access during normal business hours to such of the records of Sangamo and its respective Affiliates as may be reasonably necessary to verify the accuracy of the invoices provided by Sangamo to Shire pursuant to Section 3.3(g) for any year ending not more than 18 months prior to the date of such request. No year may be audited more than once, except for cause. The accounting firm will enter a confidentiality agreement reasonably acceptable to Sangamo governing the use and disclosure of Sangamo’s information disclosed to such firm, and such firm shall disclose to Shire only whether the invoices are correct or not and the specific details concerning any discrepancies, which information shall be Confidential Information of Sangamo.

(b) Overpayments. Unless disputed by Shire or Sangamo in good faith, if such accounting firm concludes that the amounts paid during the audited period were more or less than the amounts actually due to Sangamo, Shire shall pay any additional amounts due, and Sangamo will refund any amounts overpaid, in each case plus interest as set forth in Section 10.12, within 30 days after the date the written report of the accounting firm so concluding is delivered to Sangamo and Shire. The fees charged by such accounting firm shall be paid by Shire; provided that if the audit discloses that the amounts payable by Shire for such period have been overpaid by more than [***] percent, then, subject to Section 3.9(c), Sangamo shall pay the reasonable fees and expenses charged by such accounting firm.

(c) Audit Disputes. In the event of a good faith dispute by Shire or Sangamo regarding the result of an audit made pursuant to this Section 3.9, the Parties shall agree in good faith on an alternative independent certified public accounting firm of internationally-recognized standing to perform a second audit. If such audit is requested by Shire because Shire was found by the initial audit to have underpaid and the second audit confirms that Shire underpaid, then Shire shall bear all costs associated with the second audit. If such audit is requested by Sangamo because Shire was found by the initial audit to have overpaid and the second audit confirms that Shire overpaid, then Sangamo shall bear all costs associated with the second audit. Notwithstanding the above, in the event that the second audit confirms the findings of the first audit, the requesting Party shall pay. No over or under payment indicated by the initial audit shall be payable in the event of a dispute until the second audit is complete and such second audit shall be binding on the Parties, with any under or over payment determined thereby, plus interest as set forth in Section 10.12, being payable within 30 days after the date the written report of the accounting firm so concluding is delivered to Sangamo and Shire.

(d) Confidential Treatment. Shire shall treat all financial information disclosed by its accounting firm pursuant to this Section 3.9 as Confidential Information of Sangamo for purposes of Article 12 of this Agreement, and shall cause its accounting firm to do the same.

4.1 Composition. The Research Committee shall be formed as soon as practicable, but no later than 30 days following the Amendment Effective Date. The Research Committee shall be comprised of an equal number of representatives from each Party, up to four and initially two. Each Party shall promptly notify the other Party in writing of its initial representatives to the Research Committee, and may substitute one or more representatives from time-to-time effective upon written notice to the other Party. A designated representative [***] shall be responsible for setting the agenda for meetings of the Research Committee, with input from the other members, and for conducting the meetings of the Research Committee.

4.2 Meetings. The Research Committee shall meet in person or by teleconference not less than twice per year during the Research Term. Subject to the preceding sentence, the Research Committee shall meet on such dates and at such times and places as agreed to by the members of the Research Committee. Meetings may be in person or by tele- or videoconference. Shire shall be responsible for all its own expenses relating to attendance at or participation in Research Committee meetings, and shall reimburse all external costs incurred by Sangamo (without markup) in connection with preparing for, traveling to, attending and participating in such meetings. If the amount of time requested by Shire with respect to Sangamo’s participation on the Research Committee exceeds the maximum number of hours Sangamo is obligated to spend on such activity under the applicable Research Plan, then Shire shall reimburse Sangamo’s FTE costs (at the FTE Rate) of such participation. Within 10 days following each Research Committee meeting, Shire shall cause to be prepared and will provide to Sangamo a draft of reasonably detailed written minutes describing all matters discussed at each meeting of the Research Committee and shall provide to all representatives of the Research Committee copies of all Interim Research Reports and Final Research Reports as may be presented and discussed at each Research Committee Meeting. The minutes and the drafts of any minutes shall be the Confidential Information of both Parties.

4.3 Information Exchange. The Research Committee will be an information sharing and discussion body only and will review and discuss the activities being performed under the Research Program or a Development Plan (to the extent relevant), all Results generated under each Research Plan and all Interim Research Reports and Final Research Reports. Additionally, with respect to each Research Plan, the project leader for each Research Plan will, for information purposes only, (a) at least one Research Committee meeting each year, present to the Research Committee each then-current Research Plan and (b) at each meeting, present to the Research Committee an update of the key activities conducted and Results achieved under each then-current Research Plan.

5.1 Shire’s Diligence Obligations. Shire shall: (a) use Commercially Reasonable Efforts to file [***]; (b) for each Shire Target for which an IND or CTA is filed for a Shire ZF Product directed to such Shire Target, use Commercially Reasonable Efforts to obtain Marketing Approval for at least one therapeutic Shire ZF Product directed to such Shire Target in the United States or at least one Major European Country; and (c) use Commercially Reasonable Efforts to [***] each Shire ZF Product in [***]. Sangamo’s sole and exclusive remedy for any breach by Shire of this Section 5.1 shall be [***].

Shire’s sole and exclusive remedy for any breach by Sangamo of this Section 5.2 shall be [***].

5.3 Shire Responsibilities. After Development Candidate Selection, other than any Services to be provided by Sangamo, subject to Section 5.1, Shire shall assume sole responsibility for and have sole discretion over all development, regulatory, manufacturing and commercialization activities for Shire ZF Products (including any Shire ZF Compounds included therein), including (a) the planning, execution and submission of, and expenses associated with, IND-Enabling Studies and clinical trials of such Shire ZF Products; (b) the selection of the countries in which Shire will pursue and maintain Marketing Approvals for such Shire ZF Products and expenses related to obtaining and maintaining such Marketing Approvals; and (c) commercialization of such Shire ZF Products in the Territory and expenses associated with the commercialization of such Shire ZF Products. Shire and its Affiliates shall comply with all applicable laws, regulations and guidelines in conducting its clinical development, manufacturing and commercialization activities under this Agreement; provided, however, that Sangamo’s sole remedy for Shire’s or its Affiliate’s breach of this last sentence of Section 5.3 will be [***], and Sangamo will have [***].

(a) Sangamo ZF Products. Subject to Section 5.2, Sangamo shall have sole responsibility for and sole discretion over all development, regulatory, manufacturing and commercialization activities for Sangamo ZF Products (including any Sangamo Safe Harbor ZF Compound included therein), including (a) the planning, execution and submission of, and expenses associated with, IND-Enabling Studies and clinical trials of such Sangamo ZF Products; (b) the selection of the countries in which Sangamo will pursue and maintain Marketing Approvals for such Sangamo ZF Products and expenses related to obtaining and maintaining such Marketing Approvals; and (c) commercialization of such Sangamo ZF Products in the Territory and expenses associated with the commercialization of such Sangamo ZF Products.

(b) Selection Knowledge Transfer. No later than [***] days following each Development Candidate Selection, and in accordance with the Research Plan, with respect to such Development Candidate, Sangamo will complete the transfer to Shire of all of the following, to the extent not already in Shire’s possession: (i) Results, (ii) a written summary, in a form specified in the Research Plan, of all [***] activities (including [***]) for the applicable Target performed by Sangamo under the applicable Research Plan and (iii) all relevant Sangamo Know-How (including synthesis protocols and documentation) necessary or useful (to the extent actually used by Sangamo at such time or in the course of the Collaboration with respect to the applicable Shire Target) for Shire to manufacture supplies of such Shire ZF Product according to the specifications and manufacturing techniques then in use by Sangamo for such Shire ZF Product [***]. Sangamo will provide such technical assistance Services to Shire as necessary to complete the transfer of such Sangamo Know-How in accordance with the Research Plan. If the amount of time requested by Shire with respect to such transfer or technical assistance exceeds the maximum number of hours Sangamo is obligated to spend on such activity under the applicable Research Plan, then Shire shall reimburse Sangamo’s FTE costs (at the FTE Rate) and external costs of such technical assistance (with no mark-up thereon). In addition, reasonably promptly after the date on which Shire provides notification to Sangamo of Development Candidate Selection, (A) Sangamo will supply to Shire any then-existing supplies of any and all such Shire ZF Product (including any applicable Shire ZF Compound included therein) manufactured by or on behalf of Sangamo (except to the extent that any such supplies need to be retained by Sangamo or its manufacturer, consistent with the requirements of regulatory authorities or otherwise as required by law), and (B) to the extent any manufacturing contracts between Sangamo and a Third Party contract manufacturer are specific to such Shire ZF Product (or any applicable Shire ZF Compound included therein), Sangamo will, if permitted under the terms of the contract, assign such contract to Shire.

(c) Ownership Assignments. Following each Development Candidate Selection by Shire, with respect to such Development Candidate, Sangamo shall (i) promptly transfer to Shire all information and materials in Sangamo’s possession and Control that are required, or could reasonably be expected to be required, whether by law, regulation or otherwise, to be maintained by the holder of an IND/CTA, or that are useful or necessary to file an IND/CTA, (ii) for any information and materials of the type otherwise described in clause (i) but that are in Sangamo’s Control and in the possession of a Third Party service provider, Sangamo will either (A) if requested by Shire, assign to Shire such contract (which contract Shire shall assume), to the extent assignable, or (B) if not assignable (either by its terms or because it does not relate solely to such Shire ZF Product), provide access to such information and materials to Shire; provided that Shire bears all costs for maintenance of and access to such information and materials, (iii) provide Shire access, to the extent reasonably requested by Shire and necessary or useful for Shire to pursue the clinical development and Marketing Approval of (or the maintenance of Marketing Approval of) such Shire ZF Product, to any information and materials in Sangamo’s Control that are related to such Shire ZF Product and used or generated in conducting activities under the applicable Research Plan but are not addressed in clause (i) or (ii), which information and materials Sangamo shall maintain for two years following Development Candidate Selection and shall not thereafter destroy without providing Shire notice and the opportunity to access such information and materials, and (iv) provide, at Shire’s expense (including FTE costs and external costs), such Services as Shire may reasonably request to assist Shire in the clinical development, Marketing Approval and commercialization of such Shire ZF Product during the Royalty Period for such Shire ZF Product, to the extent that such activities are not set forth in the applicable Research Plan and Sangamo has the relevant expertise and then available capacity by functional group or is capable of acquiring sufficient capacity through the use of Commercially Reasonable Efforts.

(d) Shire ZF Compound Changes. If, after completion of activities under a Research Plan for a Shire Target, Shire desires [***] of one or more Shire ZF Compounds in the Shire ZF Product directed to such Shire Target (regardless of whether they have been designated as Development Candidates pursuant to Section 3.5), Shire shall notify Sangamo in writing, identifying the proposed change; provided that any [***] to a Shire ZF Compound shall not change the Shire Target to which such Shire ZF Compound Specifically Binds and shall not cause such Shire ZF Compound to Specifically Bind any other Target or chromosomal location other than the Shire Target. For clarity, Shire shall not have the right under this Section 5.4(d) [***] Shire ZF Compound for the purpose of [***]. Within [***] days following Sangamo’s receipt of such notice from Shire, Sangamo shall notify Shire in writing whether (i) Sangamo will conduct the necessary Services to change one or more Shire ZF Compounds in such Shire ZF Product, in which case Sangamo shall use Commercially Reasonable Efforts to [***] ZF Compound, at Shire’s expense, pursuant to a new Research Plan in

accordance with the terms of Section 3.3 or (ii) Sangamo declines to conduct any necessary Services. If Sangamo declines to conduct any necessary Exclusive Services pursuant to the preceding clause (ii), then Shire will have the right [***] to perform such Exclusive Services and (A) the exclusivity restrictions set forth in Section 3.3(a) will not apply to [***] (B) the terms of Section 3.3(c)(i) and Section 3.3(c)(ii) will apply. Except as required under Section 3.3(c)(ii), in no event will Sangamo be obligated to disclose to Shire any Know-How related to [***]. Upon successful development of the [***] ZF Compound by Sangamo or Shire, the [***] ZF Compound shall be a Shire ZF Compound.

(a) Development Plan. Each Development Plan will be developed, and amended from time to time, by Shire. Each Development Plan, including each such amendment, will be presented in the form of a written summary provided to Sangamo that includes sufficient detail for Sangamo to understand the activities planned by Shire and Shire’s anticipated timelines for performing such activities.

(b) Development Reports. Up until the time of [***] for the applicable Collaboration ZF Product, for each Collaboration ZF Product, each Responsible Party shall keep the other Party informed about the status of the Responsible Party’s preclinical and clinical development activity by providing, at least [***] and in a timely manner, detailed written updates describing such developments in a form substantially similar to that set forth on Schedule 5.5(b).

(c) Development Directed to [***]. If a particular Shire ZF Product has [***] not within the applicable Shire Target, then Shire may develop and commercialize such Shire ZF Product to treat the diseases or conditions associated with such other Target; provided that Shire will first use Commercially Reasonable Efforts to develop such Shire ZF Product for the purpose of obtaining Marketing Approval with respect to the disease or condition associated with the applicable Shire Target; and further provided that (i) at the time of Development Candidate Selection for the Shire ZF Compound in any Shire ZF Product, Shire has adopted a plan and allocated an internal team to develop such Shire ZF Product for such disease or condition, and (ii) any subsequent cessation of such development is primarily attributable to changes in the development risk profile or commercial potential for such Shire ZF Product.

(d) Safety Data Exchange Agreement. Two months prior to the first IND filing respecting any (i) ZF Product developed by Sangamo in connection with a Sangamo Target (other than a Sangamo ZF Product) or (ii) Shire ZF Product, the Parties agree to meet to negotiate and draft a detailed Safety Data Exchange Agreement in the form of Shire’s Safety Data Exchange Agreement template, as it stands at the time of such first IND filing, outlining each Party’s respective obligations surrounding pharmacovigilance activities, including but not limited to, timely transferring information related to adverse events or adverse reactions and maintaining a global safety database, to the extent required for each Party to comply with applicable laws and regulations.

6.1 Shire’s Exclusive Right to Manufacture. Except for activities conducted by Sangamo under a Research Plan, Shire shall have the exclusive right in the Territory to (and Sangamo shall not) manufacture Shire ZF Compounds and Shire ZF Products for use in the applicable Field, either directly or through one or more Affiliates or contract manufacturers selected by Shire in its sole discretion.

(c) Notice. With respect to any sublicense agreement that includes a sublicense under a Third Party License that requires Sangamo to provide the applicable Third Party licensor a copy of any sublicense agreement or a summary of the terms of such sublicense agreement, Shire shall provide Sangamo with such copy or summary within 15 days of the execution of such sublicense agreement. Any such copy or summary shall be treated by Sangamo as Shire’s Confidential Information.

For the avoidance of doubt and not by way of limitation, during the Term, Sangamo shall not work independently of this Agreement for itself or any Affiliate or Third Party (including the grant of any license to any Third Party) on any therapeutic product containing a ZF Compound or process employing a ZF Compound that, with respect to either Shire Target, corrects expression of such defective Shire Target or provides a functional copy of the protein encoded by the non-defective version of such Shire Target. Sangamo’s obligations under this Section 8.4 shall terminate with respect to a Target when it ceases to be a Shire Target and becomes a Terminated Target. Shire acknowledges that Sangamo, prior to the Effective Date, entered into agreements pursuant to which it granted licenses to Third Parties with respect to research and agricultural uses of ZF Compounds and that such licenses are not prohibited by this Section 8.4.

8.5 Competing Program Acquisition. If Sangamo acquires a Third Party that is, prior to such acquisition, conducting research on, developing or commercializing a product or service described in the first two sentences of Section 8.4, Sangamo shall (a) promptly provide written notice to Shire regarding such acquisition, [***].

8.6 Sangamo Program Buy-Back Right. Sangamo shall notify Shire in writing (the “ROFN Notice”) promptly if during the Term Sangamo decides to initiate discussions with a Third Party with respect to a license to commercialize one or more Sangamo ZF Products or an acquisition of Sangamo’s assets related to one or more Sangamo ZF Products (any such license or acquisition with respect to the applicable Sangamo ZF Products, a “Sangamo Program License”); provided, however, that Sangamo may not grant any [***]. Within [***] after Shire’s receipt of the ROFN Notice, Shire shall notify Sangamo of whether or not it is interested in entering into discussions with Sangamo with respect to the applicable Sangamo Program License, and following Sangamo’s receipt of such notice from Shire, Sangamo shall provide to Shire (if not previously provided) a complete set of then-available data and information in Sangamo’s Control for the applicable Sangamo ZF Products to which the Sangamo Program License relates [***] (collectively, the “Required ROFN Information”). For clarity, this Section 8.6 does not apply to a Change of Control of Sangamo as described in Section 1.8(a), (b) or (c) or any discussions related thereto.

(a) ROFN. If, within [***] days following its receipt of the Required ROFN Information from Sangamo, Shire notifies Sangamo that Shire desires to negotiate with respect to such Sangamo Program License, then the Parties will exclusively negotiate in good faith regarding the terms under which Shire might obtain a Sangamo Program License with respect to such Sangamo ZF Product, which terms may include an [***] days commencing upon Shire’s receipt of such Required ROFN Information (the “ROFN”). In addition, Sangamo shall provide any updates to the Required ROFN Information to Shire that come into Sangamo’s Control during the applicable ROFN period.

(b) ROFN Suspension. If Shire does not notify Sangamo of its desire to negotiate with respect to a Sangamo Program License during the initial [***] day period under Section 8.6 or in the [***] day period following Sangamo’s provision of the

Required ROFN Information, or if the Parties do not enter into a definitive agreement within the [***] day ROFN period, then Shire’s ROFN for the applicable Sangamo ZF Products will be suspended [***] and [***] Sangamo may enter into a Sangamo Program License with respect to such Sangamo ZF Products with any Third Party; provided that if the Parties commenced negotiations during such ROFN period, the terms of the definitive agreement extended by the Third Party, when taken as a whole, are more favorable to Sangamo than those extended by Shire to Sangamo in its last written offer during such ROFN period described in Section 8.6(a). For clarity, in the event that [***], and Shire will have no further ROFN with respect to the applicable Sangamo ZF Products, and if Sangamo enters into a Sangamo Program License with Shire, then Sangamo will no longer be [***] of those Sangamo ZF Products licensed or assigned under such Sangamo Program License (unless specified in the applicable definitive agreement).

(c) ROFN Reinstatement. If Sangamo does not enter into a Sangamo Program License with a Third Party [***] described in Section 8.6(b) with respect to such applicable Sangamo ZF Product, [***] within such Sangamo Program during such [***] period, then Shire’s ROFN will be reinstated if Sangamo decides to initiate or continue licensing or acquisition discussions with respect to the same Sangamo Program License or a new Sangamo Program License, consistent with the terms and conditions of Section 8.6(a) and Section 8.6(b). [***] Sangamo entering into a Sangamo Program License with respect to such Sangamo ZF Product, then Sangamo shall promptly deliver to Shire [***] over a [***].

8.7 Other Sangamo Programs. Sangamo shall notify Shire promptly if it decides to [***], or if it is contacted by a Third Party to [***], in each case other than a Sangamo Program License but with respect to a [***] that is directed to a [***]; provided, however, that Sangamo shall not be obligated to [***]. Upon Shire’s request within [***] after such notice, the Parties will negotiate in good faith for up to [***] (the “Negotiation Period”) regarding the terms under which Sangamo might [***]. Sangamo may engage in [***].

8.8 No Implied Rights. Except as expressly provided in this Agreement, neither Party shall be deemed by estoppel, implication or otherwise to have granted the other Party any license or other right with respect to any intellectual property of such Party.

8.9 Negative Covenant. Each Party covenants that it will not knowingly use or practice any of the other Party’s intellectual property rights licensed to it under this Article 8 except for the purposes expressly permitted in the applicable license grant.

8.10 Third Party Licenses. The licenses granted to Shire in Section 8.1 include sublicenses under Sangamo Licensed Technology licensed to Sangamo pursuant to Third Party Licenses, which sublicenses are subject to the terms set forth on Schedule 8.10A, which terms Shire hereby acknowledges. Schedule 8.10B sets forth those obligations under the Third Party License that are obligations of Shire under this Agreement.

To the extent that Sangamo obtains a license to any Third Party intellectual property rights after the Effective Date and Sangamo Controls such intellectual property rights licensed thereunder as provided in Section 11.4(b) such that such intellectual property rights are sublicensed to Shire under Article 8, Shire shall pay to Sangamo all applicable payments under such license, as described in Section 11.4(b), within 30 days after the applicable due date in such Third Party License and provide to Sangamo, at least 10 days before the applicable due date in such Third Party License all reports required under the applicable license agreement between Sangamo and such Third Party on account of Shire’s and its Affiliates’ and Sublicensees’ development, manufacture and commercialization of Shire ZF Products, such that Sangamo may comply with all payment and reporting obligations under such license agreements. Provided it receives such items in a timely manner, Sangamo shall pay such amounts to, and file such reports with, the applicable Third Party on or before the applicable due date.

(a) Timing of Reports. Within 45 days after the end of each calendar quarter during the Royalty Period, the Responsible Party shall furnish to the other Party a written report showing in reasonably specific detail, on a Collaboration ZF Product-by-Collaboration ZF Product and country-by-country basis: (i) the Gross Sales of all Collaboration ZF Product sold by such Responsible Party, its Sublicensees hereunder and their respective Affiliates during such calendar quarter, (ii) the calculation of Net Sales from Gross Sales of the applicable Collaboration ZF Product, (iii) the withholding taxes, if any, required by law to be deducted with respect to royalties due on such sales and (iv) the exchange rates, if any, used in determining the amount payable by the Responsible Party to the other Party in United States dollars.

(b) Currency Conversion. With respect to sales of all Collaboration ZF Product invoiced in United States dollars, all such amounts shall be expressed in United States dollars. With respect to sales of Collaboration ZF Product invoiced in a currency other than United States dollars, all such amounts shall be expressed both in the currency in which the amount is invoiced and in the United States dollar equivalent. Whenever for the purpose of calculating Net Sales, conversion from any foreign currency shall be required, the amount of such sales in foreign currencies shall be converted into U.S. dollars using the exchange rate for the relevant month as determined by Shire’s accounting policies (the “Monthly Rate”), such Monthly Rate being determined as the last price rate of exchange for such currencies on the last business day of the immediately preceding calendar month as published on Bloomberg page FXC (or such other publication as may be agreed between the Parties from time-to-time).

(c) Records. The Responsible Party shall keep complete and accurate records in sufficient detail to enable the royalties payable under this Article 10 to be determined.

(a) Audit Frequency. Upon 14 days advance written request by a Party and not more than once in each calendar year, the Responsible Party, its Sublicensees and their Affiliates shall permit an independent certified public accounting firm of internationally-recognized standing, selected by the auditing Party and reasonably acceptable to the Responsible Party, at the auditing Party’s

expense, to have access during normal business hours to such of the records of the Responsible Party, its Sublicensees hereunder and their respective Affiliates as may be reasonably necessary to verify the accuracy of the royalty reports hereunder for any year ending not more than 18 months prior to the date of such request. No year may be audited more than once, except for cause. The accounting firm will enter a confidentiality agreement reasonably acceptable to the Responsible Party governing the use and disclosure of the Responsible Party’s information disclosed to such firm, and such firm shall disclose to the auditing Party only whether the reports are correct or not and the specific details concerning any discrepancies, which information shall be Confidential Information of the Responsible Party.

(b) Audit Payments. Unless disputed by Shire or Sangamo in good faith, if such accounting firm concludes that the royalties paid during the audited period were more or less than the royalties due, the Responsible Party shall pay any additional amounts due, and the other Party will refund any amounts overpaid, in each case plus interest as set forth in Section 10.12, within 30 days after the date the written report of the accounting firm so concluding is delivered to Sangamo and Shire. The fees charged by such accounting firm shall be paid by the auditing Party; provided that if the audit discloses that the royalties payable by the Responsible Party for such period have been underpaid by more than [***], then, subject to Section 10.8(c), the Responsible Party shall pay the reasonable fees and expenses charged by such accounting firm.

(c) Audit Disputes. In the event of a good faith dispute by Shire or Sangamo regarding the result of an audit made pursuant to this Section 10.8, the Parties shall agree in good faith on an alternative independent certified public accounting firm of internationally-recognized standing to perform a second audit. If such audit is requested by the Responsible Party because the Responsible Party was found by the initial audit to have underpaid and the second audit confirms that the Responsible Party underpaid, then the Responsible Party shall bear all costs associated with the second audit. If such audit is requested by the auditing Party under Section 10.8(a) because the Responsible Party was found by the initial audit to have overpaid and the second audit confirms that the Responsible Party overpaid, then the auditing Party shall bear all costs associated with the second audit. Notwithstanding the above, in the event that the second audit confirms the findings of the first audit, the requesting Party shall pay. No over or under payment indicated by the initial audit shall be payable in the event of a dispute until the second audit is complete and such second audit shall be binding on the Parties, with any under or over payment determined thereby, plus interest as set forth in Section 10.12, being payable within 30 days after the date the written report of the accounting firm so concluding is delivered to Sangamo and Shire.

(d) Confidential Treatment. The auditing Party shall treat all financial information disclosed by its accounting firm pursuant to this Section 10.8 as Confidential Information of the Responsible Party for purposes of Article 12 of this Agreement, and shall cause its accounting firm to do the same.

(a) Reasonable Assistance. Each Party shall use reasonable efforts to minimize tax withholding on payments made to the other Party pursuant to this Agreement and shall cooperate with the other Party’s efforts to do so. Notwithstanding such efforts, if a paying Party concludes that tax withholdings under the laws of any country are required with respect to payments to the other Party pursuant to this Agreement, such paying Party shall first notify the receiving Party and provide such receiving Party within 20 days to determine whether there are actions either Party can undertake to eliminate or reduce such withholding. The paying Party shall refrain from making such payment to the receiving Party unless and until the earlier of (i) the receiving Party’s written instructions to make such payment, if the receiving Party instructs the paying Party by written notice during such 20-day period that the receiving Party intends to take actions (satisfactory to both Parties) that shall obviate or reduce the need for such withholding, and provides to the paying Party satisfactory evidence that such actions have been taken by the receiving Party, in which case the paying Party shall provide any reasonable cooperation requested by the receiving Party, (ii) the date the paying Party instructs the receiving Party by written notice during such 20-day period that it should make such payment and withhold the required amount and pay it to the appropriate Governmental Authority or (iii) expiration of such 20-day period without notice from the receiving Party under the preceding clauses (i) or (ii). For clarity, payment and withholding in accordance with this Section 10.9(a) shall not be considered a Withholding Tax Action for the purposes of Section 10.9(b). If the paying Party withholds any taxes from a payment under this Agreement, the paying Party shall submit appropriate proof of payment of the withholding taxes to the other Party within a reasonable period of time. Upon request, the paying Party shall give the other Party such reasonable assistance, which shall include the provision of appropriate certificates of such deductions made together with other supporting documentation as may be required by the relevant tax authority, to enable such Party to claim exemption from such withholding or other tax imposed or obtain a repayment thereof or reduction thereof and shall upon request provide such additional documentation from time-to-time as is reasonably required to confirm the payment of tax.

(b) Withholding Tax Actions. Notwithstanding Section 10.9(a), if the paying Party is required to make a payment to the other Party that is subject to a deduction or withholding of tax, then if such withholding or deduction obligation arises as a result of any action by the paying Party, including any assignment or sublicense, or any failure on the part of the paying Party to comply with applicable laws or filing or record retention requirements, that has the effect of modifying the tax treatment of the Parties hereto (a “ Withholding Tax Action”), then the sum payable by the paying 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 Withholding Tax Action occurred.

(c) Withholding Tax Deductions. Notwithstanding Section 10.9(a), if the paying Party is required to make a payment to the other Party that is subject to a deduction or withholding of tax, then if such withholding or deduction obligation arises as a result of any action by such non-paying Party, including any assignment or any failure on the part of such Party to comply with applicable laws or filing or record retention requirements, that has the effect of modifying the tax treatment of the Parties hereto, then the sum payable by the paying Party (in respect of which such deduction or withholding is required to be made) shall be made to such non-paying Party after deduction of the amount required to be so deducted or withheld, which deducted or withheld amount shall be remitted to the proper Governmental Authority in accordance with applicable laws.

(a) All payments stated in Section 2.2(c), Section 3.3 and Section 10.1 of this Agreement are for the purposes of VAT considered to be both exclusive of VAT and consideration for the supply of services.

(b) For the purposes of this Section 10.10, references to a Party refer not only to such Party but also to any business that this Agreement or part interest in this Agreement may be transferred to by such Party.

(c) For the purposes of VAT, the services performed by either Party under this agreement shall be considered to be covered by Art 44 of Council Directive 2006/112/EC (or any equivalent provision in the country of performance if performed outside the European Union) and as such will be considered to be liable for VAT in the country where the recipient is established. For the purposes of this agreement, it is understood that Sangamo is established in the USA and Shire is established in Switzerland.

(d) If at any stage, the local tax authorities assert that they consider the services performed by either Party to be subject to local VAT, the Party performing such services shall in the first instance undertake all reasonable steps to refute any such assertions by the local tax authority. Only once this process is completed should the Party performing services raise valid tax invoices for the additional VAT liability.

(e) The Party receiving services under this Agreement shall take all reasonable steps to recover any additional VAT liability from the same local tax authorities by submitting regular claims. The Party providing services under this Agreement shall provide all reasonably necessary assistance to facilitate the recovery of this tax. However, if in the event that the tax cannot be recovered then the Party receiving services shall be entitled to offset this tax against future payments to the Party providing services.

(f) The responsibility for paying any penalties or interest accruing to incorrect VAT treatment of the supplies made by Sangamo will rest with Sangamo.

(g) Should these any services performed under this Agreement be considered to be subject to Art 44 of Council Directive 2006/112, each of Sangamo and Shire warrants that it will fulfill all its necessary VAT reporting requirements in respect of such services.

(h) In the event that an invoice is raised that is subject to VAT but is raised in a currency other than the local currency of the territory from where the tax is being charged, the invoice must additionally display this tax in the local currency of the territory having been converted using the relevant monthly exchange rate published on Bloomberg.

(i) Sangamo hereby represents and warrants that, as of the Amendment Effective Date, it is not, has never been and has no obligation for whatever reason to be established for VAT purposes in any jurisdiction outside the United States of America. Solely on this basis Shire acknowledges and agrees that: (i) as of the Amendment Effective Date, it is a fully taxable entity for VAT purposes in Switzerland; and (ii) as of the Amendment Effective Date, Shire expects to recover any self-assessed Swiss VAT that Shire will need to report to the Swiss VAT authorities in relation to payments to made by Shire to Sangamo under this Agreement.

(j) In the event that this Agreement is terminated, Shire will be entitled to withhold from any remaining sums payable to Sangamo any outstanding VAT claims from the local tax authority. These sums will be paid to Sangamo upon successful refunding of the claims from the local tax authority.

10.11 Payment Method. All payments by the paying Party to the other Party hereunder shall be in United States dollars in immediately available funds and shall be made by wire transfer to a bank account designated in writing to the paying Party by the other Party.

10.12 Late Payments. If a Party does not receive payment of any sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due to the Party from the due date until the date of payment at a per-annum rate of two percent over the then-current prime rate reported in The Wall Street Journal or the maximum rate allowable by applicable laws, whichever is lower.

(a) Inventions. Except as provided in Section 11.1(b), (i) each Party, as between such Party and the other Party, shall own all Know-How conceived, discovered, invented, created, made or reduced to practice or tangible medium solely by employees, agents or contractors of such Party (and all Patent Rights claiming such Know-How), and (ii) the Parties shall jointly own and have an undivided one-half interest in and to all Joint Know-How and Joint Patent Rights. All determinations of inventorship under this Agreement shall be made in accordance with the patent law of the United States. Each Party may exploit any Joint Technology without accounting to or obtaining consent from the other Party, subject to the exclusive licenses of each Party’s interest thereunder granted, as part of the Sangamo Licensed Technology under Section 8.1 and as part of the Shire Licensed Technology under Section 8.2(b), provided, however, that nothing in this Section 11.1(a) shall be construed as a grant to any other intellectual property held by the other Party.

(b) Shire [***] Patent Rights. Sangamo [***] Shire, Sangamo’s [***] to any Shire [***] Patent Rights. In each case, Sangamo shall execute and deliver to Shire [***], in a mutually agreeable form, within 30 days after such Patent Right comes into existence. Any such Shire [***] Patent Rights shall [***] constitute Confidential Information of Shire for the purposes of this Agreement [***] to Sangamo in accordance with this Section 11.1(b), in which case it shall constitute the Confidential Information of Sangamo. Notwithstanding the foregoing or anything to the contrary in this Agreement, Shire shall not, directly or indirectly through Affiliates or Third Parties, practice any of the Shire [***] Patent Rights outside of the scope of the licenses granted to Shire under this Agreement. For any Patent Right that ceases to be a Shire [***] Patent Right at any time during the Term by virtue of an amendment of the claims, Shire shall [***], effective as of the date of such claim amendment, its entire right, title and interest in and to each such Patent Right to Sangamo. In each case, Shire shall execute and deliver to Sangamo a [***], in a mutually agreeable form, within 30 days after the date such Patent Right ceased to be a Shire [***] Patent Right.

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

(i) Preparation of Shire [***] Patent Rights. With respect to the preparation of any patent application that will be a Shire [***] Patent Right, the Parties shall collaborate in reviewing relevant data, in preparing drafts, and in preparing a final version for filing of such patent application. Shire shall have [***], respecting the content of any application that will be a Shire [***] Patent Right; provided that Shire shall not include in any such application any information beyond that required to meet the requirements of 35 U.S.C. § 112. Shire shall consider in good faith, take into account, and implement where possible the reasonable comments made by Sangamo respecting the preparation and content of any Shire [***] Patent Rights. For the avoidance of doubt, Sangamo [***]. For the purpose of this Section 11.2(a)(i), a [***] means a claim that (A) includes language that specifically describes one or more ZF Compounds that Specifically Bind a particular Shire Target, (B) if presumed to be issued, would not be infringed by a ZF Compound (or the manufacture or use of a ZF Compound) that, after reasonable inquiry (i) at the time such Patent Right is filed or (ii) with respect to a claim that is first proposed after filing, at the time of such initial proposal, is known to not Specifically Bind such Shire Target, if such ZF Compound were combined with the non-ZF Compound elements, if any, in such claim, (C) does not include language that specifically describes a product (or the manufacture or use of such product) that is not a Shire ZF Product, and (D) does not include language describing any product (other than a Shire ZF Compound) or process that is Know-How, whether patentable or not, conceived, discovered, invented, created, made or reduced to practice or tangible medium, whether solely or jointly, by one or more employees, agents or contractors of Sangamo, if such Know-How is being protected as a trade secret by Sangamo, or is the subject of a claim in an existing Patent Right controlled by Sangamo, or is sufficiently disclosed in an existing Patent Right controlled by Sangamo to support a claim to such Know-How in such Patent Right under 35 U.S.C. § 112 (first paragraph), or if Sangamo has not yet filed an intended patent application disclosing or claiming such Know-How (and Sangamo discloses to Shire during the review process described in Section 11.2(a)(i) or (ii), as applicable, that Sangamo intends to file such a patent application), unless Sangamo consents in writing to the inclusion of such Know-How.

(ii) Filing, Prosecution and Maintenance of Shire [***] Patent Rights. Shire, at its own expense, shall have the sole right (subject to Section 11.2(e)) to [***]. Shire shall [***], including by providing Sangamo with [***] and shall provide Sangamo [***], within a reasonable amount of time in advance of [***]. Shire shall consider in good faith, take into account and implement where possible the [***]; provided that, Shire shall not be required to [***] where Shire reasonably determines that [***].

(i) Sangamo, at its own expense, shall have the sole right (subject to Section 11.2(f)) to prepare, file, prosecute and maintain, throughout the world, the Sangamo Patent Rights.

(ii) Sangamo shall keep Shire informed as to material developments with respect to the filing, prosecution and maintenance of such Sangamo Patent Rights, including by providing Shire with copies of all material communications (including office actions and notices of interferences, reissues, re-examinations or oppositions) from any patent office regarding such Sangamo Patent Rights and shall provide Shire drafts of submissions relating thereto, including drafts of any material filings or responses to be made to such patent offices, including notice of all interferences, reissues, re-examinations, oppositions or requests for patent term extensions, within a reasonable amount of time in advance of submitting such filings or responses to permit Shire an opportunity to review and comment thereon. Sangamo shall consider in good faith, take into account and implement where possible the reasonable comments made by Shire, including comments directed to preventing any detrimental effect of Sangamo’s patent prosecution actions on the prosecution or enforcement of [***]; provided that Sangamo does not reasonably determine such comments to be detrimental to the prosecution or enforcement of any [***].

(d) Joint Patent Rights. If the Parties make any Joint Know-How, the Parties shall promptly meet to discuss and determine whether to seek Joint Patent Rights thereon. If either Party decides to seek any Joint Patent Rights, then Sangamo shall have the first right, but not the obligation, to prepare, file, prosecute and maintain throughout the world, at its expense, any Joint Patent Right (other than a Shire [***] Patent Right, the prosecution of which is governed by Section 11.2(a)) that claims the composition, manufacture or use of a ZF Compound or of a product or method containing, employing or made using a ZF Compound, using patent counsel or patent agent selected by Sangamo and reasonably acceptable to Shire. Shire shall have the first right, but not the obligation, to prepare, file, prosecute and maintain throughout the world, at its expense, any other Joint Patent Right [***]; using patent counsel or patent agent selected by Shire and reasonably acceptable to Sangamo. The prosecuting Party shall keep the non-prosecuting Party informed as to material developments with respect to the filing, prosecution and maintenance of the Joint Patent Rights, including by providing copies of all material communications (including office actions and notices of interferences, reissues, re-examinations or oppositions) from any patent office regarding such Joint Patent Rights and shall provide the non-prosecuting Party drafts of submissions relating thereto, including drafts of any material filings or responses to be made to such patent offices, within a reasonable amount of time in advance of submitting such filings or responses to permit the non-prosecuting Party an opportunity to review and comment thereon. The prosecuting Party shall consider in good faith, take into account and implement where possible the reasonable comments made by the non-prosecuting Party.

(e) Shire Abandonment. If Shire elects not to file a patent application covering any Joint Know-How or Know-How that would be a Shire [***] Patent Right, or elects to cease the prosecution and maintenance of any Joint Patent Right or Shire [***] Patent Right in any country or as a PCT application (and does not elect to file one or more new patent applications covering the subject matter claimed in such Patent Right), Shire will promptly provide Sangamo with written notice, but not less than 30 days if reasonably practicable, before any action is required, and will permit Sangamo, at Sangamo’s sole discretion and expense, to file such patent application or continue prosecution or maintenance of such patent application or patent in such country, as applicable. Upon request from Sangamo, Shire will execute such documents and perform such acts as may be reasonably necessary to permit Sangamo to make such filing or continue such prosecution or maintenance, as applicable, in Shire’s name. Notwithstanding the foregoing, if such Patent Right is a Shire [***] Patent Right that (i) would have been solely owned by Sangamo but for the [***] pursuant to Section 11.1(b) and is a filing in Australia, Canada, a Major European Country, Japan or the United States, then Shire [***], effective upon Sangamo’s written request, to Sangamo all of Shire’s right, title and interest in such Shire [***] Patent Right in such jurisdiction or (ii) would have been jointly owned by the Parties but for the [***] pursuant to Section 11.1(b) and is a filing in Australia, Canada, a Major European Country, Japan or the United States, then Shire shall [***], effective upon Sangamo’s written request, to Sangamo an undivided one-half interest in such Shire [***] Patent Right in such jurisdiction. Such [***] Patent Rights shall not, after [***] from Shire to Sangamo pursuant to the preceding sentence, be included in Sangamo Patent Rights if they pertain to Australia, Canada, a Major European Country, Japan or the United States.

(f) Sangamo Abandonment. If Sangamo elects not to file a patent application covering any Joint Know-How, or elects to cease the prosecution and maintenance of any Sangamo Patent Right or Joint Patent Right in any country or as a PCT application (and does not elect to file one or more new patent applications covering the subject matter claimed in such Sangamo Patent Right or Joint Patent Right, as applicable), Sangamo will promptly provide Shire with written notice, but not less than 30 days before any action is required, and will permit Shire, at Shire’s sole discretion and expense, to continue prosecution or maintenance of any such Sangamo Patent Right or Joint Patent Right in such country, as applicable, to the extent that no Third Party has a prior right to assume the prosecution or maintenance of such Sangamo Patent Right. Upon request from Shire, Sangamo will execute such documents and perform such acts as may be reasonably necessary to permit Shire to continue such prosecution or maintenance, as applicable.

(g) Patent Term Extensions. In connection with the Marketing Approval of a Shire ZF Product, Shire shall consult with Sangamo before determining which Patent Right, if any, is to be extended, by way, for example, of a Patent Term Restoration and a Supplementary Protection Certificate. Shire shall not have the right to extend in any country (i) a Sangamo Patent Right or (ii) a Joint Patent Right that is the subject of any such extension for a product other than a Shire ZF Product. Shire shall have the sole discretion

to determine whether a Shire Patent Right or a Shire [***] Patent Right is to be extended. Sangamo shall have the sole discretion to determine whether a Sangamo Patent Right is to be extended. Each Party shall cooperate with the other Party to the extent reasonably requested by such Party to effectuate the intent of this Section 11.2(g).

(h) Orange Book Listing. In connection with the Marketing Approval of a Collaboration ZF Product, the Responsible Party shall have the sole right, in accordance with applicable laws and regulations, to choose whether a patent is to be listed in the Orange Book or in any similar equivalent thereto in the Territory. The other Party shall cooperate with the Responsible Party to the extent reasonably requested by the Responsible Party to effectuate the intent of this Section 11.2(h).

(i) Third Party Rights. For the avoidance of doubt, Shire’s rights under this Section 11.2 to [***], and Sangamo’s rights under this Section 11.2 to file, prosecute and maintain any Shire Patent Right Controlled by Shire pursuant to a Third Party License may be exercised in Shire’s name and for the benefit of Shire; provided that this Section 11.2 shall be subject to the terms of such Third Party License.

(a) Notice. If either Shire or Sangamo becomes aware of any infringement, anywhere in the world, of (i) any issued patent within the Sangamo Patent Rights or Joint Patent Rights on account of any Third Party’s manufacture, use or sale of a Shire ZF Compound or Shire ZF Product in the Field, or (ii) any issued patent within the Shire [***] Patent Rights (a “Shire ZF Product Infringement”), such Party will promptly notify the other Party in writing to that effect. If either Sangamo or Shire becomes aware of any infringement, anywhere in the world, of any issued patent within the Shire Patent Rights or Joint Patent Rights on account of a Third Party’s manufacture, use or sale of a Sangamo Safe Harbor ZF Compound or a Sangamo ZF Product in the Field (a “Sangamo ZF Product Infringement”), such Party will promptly notify the other Party in writing to that effect.

(b) Enforcement of Joint Patent Rights and Shire [***] Patent Rights against a Shire ZF Product Infringer.

(i) In the case of any Shire ZF Product Infringement, Shire shall have the first right, but not the obligation, to take action to obtain a discontinuance of the Shire ZF Product Infringement or bring suit against the applicable Third Party (such Third Party, the “Shire ZF Product Infringer”) under the applicable Joint Patent Rights and Shire [***] Patent Rights, within six months from the date of notice and, if with respect to the Joint Patent Rights, to join Sangamo as a party plaintiff. Shire shall bear all the expenses of any suit brought by it claiming Shire ZF Product Infringement of any such Patent Rights. Sangamo shall cooperate with Shire in any such suit as reasonably requested by Shire and at Shire’s expense and shall have the right to consult with Shire and to participate in and, if appropriate, be represented by independent counsel in such litigation at its own expense. Shire shall not, without Sangamo’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Sangamo or admits the invalidity or unenforceability of any such Patent Rights, which consent shall not be unreasonably withheld, conditioned or delayed. If Shire has not taken steps to obtain a discontinuance of infringement of such Patent Rights or filed suit against any such infringer of such Patent Rights within six months from the date of notice of such Shire ZF Product Infringement, then Sangamo shall have the right, but not the obligation, to bring suit against such Shire ZF Product Infringer; provided that Sangamo shall bear all the expenses of such suit. Shire shall cooperate with Sangamo in any such suit for infringement of such Patent Rights brought by Sangamo against a Shire ZF Product Infringer (including joining as a party plaintiff) at Sangamo’s request and expense, and shall have the right to consult with Sangamo and to participate in and be represented by independent counsel in such litigation at its own expense. Sangamo shall not, without Shire’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Shire or admits the invalidity or unenforceability of any such Patent Rights, or adversely impacts Shire’s Net Sales, or impacts market share, of Shire ZF Products. The enforcing Party under this Section 11.3(b)(i) shall keep the other Party reasonably informed of all material developments in connection with any such suit.

(ii) Any recoveries obtained by either Party as a result of any proceeding against a Shire ZF Product Infringer under this Section 11.3(b) shall be allocated as follows:

(A) Such recovery shall first be used to reimburse the enforcing Party for all out-of-pocket litigation costs in connection with such litigation paid by that Party, and then to reimburse out-of-pocket litigation costs paid by the other Party;

(B) With respect to any remaining portion of such recovery, Sangamo shall receive an amount equal to [***] of such amount; and

(C) Any amounts paid to Sangamo pursuant to Section 11.3(b)(ii)(B) will count towards the Royalty Cap on payments to be made by Shire to Sangamo.

(c) Shire ZF Product Infringement of Sangamo Patent Rights. With respect to any Shire ZF Product Infringement of a Sangamo Patent Right, Sangamo shall have the first right, but not the obligation, to take action to obtain a discontinuance of the Shire ZF Product Infringement or bring suit against the applicable Shire ZF Product Infringer under the applicable Sangamo Patent Rights within six months from the date of notice and to join Shire as a party plaintiff. Sangamo shall bear all the expenses of any suit brought by it claiming Shire ZF Product Infringement of any such Patent Rights. Shire shall cooperate with Sangamo in any such suit as

reasonably requested by Sangamo and at Sangamo’s expense and shall have the right to consult with Sangamo and to participate in and, if appropriate, be represented by independent counsel in such litigation at its own expense. Sangamo shall not, without Shire’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Shire or admits the invalidity or unenforceability of any such Patent Rights, which consent shall not be unreasonably withheld, conditioned or delayed. If Sangamo has not taken steps to obtain a discontinuance of Shire ZF Product Infringement of such Patent Rights or filed suit against any such Shire ZF Product Infringer of such Patent Rights within [***] months from the date of notice of such Shire ZF Product Infringement, then upon Sangamo’s written consent (not to be unreasonably withheld, conditioned or delayed), Shire shall have the right, but not the obligation, to bring suit under such Sangamo Patent Rights against such Shire ZF Product Infringer; provided that Shire shall bear all the expenses of such suit. Sangamo shall cooperate with Shire in any such suit for infringement of such Patent Rights brought by Shire against a Shire ZF Product Infringer (including joining as a party plaintiff) at Shire’s expense, and shall have the right to consult with Shire and to participate in and be represented by independent counsel in such litigation at its own expense. Shire shall not, without Sangamo’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Sangamo or admits the invalidity or unenforceability of any such Patent Rights. The enforcing Party under this Section 11.3(c) shall keep the other Party reasonably informed of all material developments in connection with any such suit.

(i) Recoveries. Any recoveries obtained by either Party as a result of any proceeding against a Shire ZF Product Infringer under this Section 11.3(c) shall be allocated as follows:

(B) With respect to any remaining portion of such recovery, Sangamo shall receive an amount equal to [***] of such amount; and

(C) Any amounts paid to Sangamo pursuant to Section 11.3(c)(i)(B) will count towards the Royalty Cap on payments to be made by Shire to Sangamo.

(ii) Third Party Rights. For the avoidance of doubt, with respect to any Sangamo Patent Right licensed to Sangamo by a Third Party, Shire’s rights under this Section 11.3(c) may be exercised in Sangamo’s name, provided that Shire’s rights under this Section 11.3(c) shall be subject to the rights of such Third Party to enforce such Sangamo Patent Right and to receive a portion of any recoveries obtained as a result of any proceeding against a Third Party infringer under such Sangamo Patent Right.

(d) Other Infringement of Joint Patent Rights. With respect to any Third Party infringement of any Joint Patent Right, other than in the case of a Shire ZF Product Infringement of a Joint Patent Right, which is subject to Section 11.3(b), or a Sangamo ZF Product Infringement of a Joint Patent Right, which is subject to Section 11.3(e), each Party shall promptly notify the other Party of such infringement and the Parties shall meet as soon as reasonably practicable thereafter to discuss such infringement and determine an appropriate course of action. Unless the Parties agree to jointly address such infringement, if the infringement relates to ZF Compounds or ZF Products or their manufacture, delivery or use, Sangamo shall have the first right but not the obligation, and if the infringement does not relate to ZF Compounds or ZF Products, Shire shall have the first right but not the obligation, to bring an action against such infringer or otherwise address such alleged infringement within six months from the date of notice and to control such litigation or other means of addressing such infringement. If, after the expiration of the [***] month period (or, if earlier, the date upon which the Party with the first right provides written notice that it does not plan to bring suit), the Party with the first right has not obtained a discontinuance of infringement of such Joint Patent Right or filed suit against any such infringer of such Joint Patent Right, then the other Party shall have the right, but not the obligation, to bring suit against such infringer of such Joint Patent Right; provided that such other Party shall bear all the expenses of such suit. In any suit under this Section 11.3(c), the non-enforcing Party shall cooperate with the enforcing Party, at the enforcing Party’s request and expense, in any such suit and shall have the right to consult with the enforcing Party and to participate in and be represented by independent counsel in such litigation at its own expense. Any recoveries obtained by either Party as a result of any such proceeding against a Third Party infringer shall be allocated as follows:

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

(ii) With respect to any remaining portion of such recovery, the enforcing Party shall receive an amount equal to [***], and the other Party shall receive the remaining [***] if the Parties brought such proceeding jointly, such remaining portion shall be [***].

(i) In the case of any Sangamo ZF Product Infringement, Sangamo shall have the first right, but not the obligation, to take action to obtain a discontinuance of the Sangamo ZF Product Infringement or bring suit against the applicable Third Party (such Third Party, the “Sangamo ZF Product Infringer”) under the applicable Shire Patent Rights or Joint Patent Rights, within [***] from the date of notice and to join Shire as a party plaintiff. Sangamo shall bear all the expenses of any suit brought by it claiming

Sangamo ZF Product Infringement of any such Patent Rights. Shire shall cooperate with Sangamo in any such suit as reasonably requested by Sangamo and at Sangamo’s expense and shall have the right to consult with Sangamo and to participate in and, if appropriate, be represented by independent counsel in such litigation at its own expense. Sangamo shall not, without Shire’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Shire or admits the invalidity or unenforceability of any such Patent Rights, which consent shall not be unreasonably withheld, conditioned or delayed. If Sangamo has not taken steps to obtain a discontinuance of infringement of such Patent Rights or filed suit against any such infringer of such Patent Rights within [***] from the date of notice of such Sangamo ZF Product Infringement, then Shire shall have the right, but not the obligation, to bring suit against such Sangamo ZF Product Infringer; provided that Shire shall bear all the expenses of such suit. Sangamo shall cooperate with Shire in any such suit for infringement of such Patent Rights brought by Shire against a Sangamo ZF Product Infringer (including joining as a party plaintiff) at Shire’s request and expense, and shall have the right to consult with Shire and to participate in and be represented by independent counsel in such litigation at its own expense. Shire shall not, without Sangamo’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Sangamo or admits the invalidity or unenforceability of any such Patent Rights, or adversely impacts Sangamo’s Net Sales, or impacts market share, of Sangamo ZF Products. The enforcing Party under this Section 11.3(e)(i) shall keep the other Party reasonably informed of all material developments in connection with any such suit.

(ii) Any recoveries obtained by either Party as a result of any proceeding against a Sangamo ZF Product Infringer under this Section 11.3(e) shall be allocated as follows:

(B) With respect to any remaining portion of such recovery, Shire shall receive an amount equal to [***]; and

(C) Any amounts paid to Shire pursuant to Section 11.3(e)(ii)(B) will count towards the Royalty Cap on payments to be made by Sangamo to Shire.

(f) EU Unitary Patent System. Without limitation of Shire’s rights under Section 11.4, Shire shall, following consultation with Sangamo and good faith consideration of Sangamo’s comments, have the exclusive right to opt-in and opt-out (i) the Joint Patent Rights that do not claim the composition, manufacture or use of a ZF Compound or product or method containing, employing or made using a ZF Compound (unless any such Patent Right is a unitary European patent) and (ii) the Shire [***] Patent Rights from the jurisdiction of the EU Unified Patent Court, in accordance with the terms of Unified Patent Court Regulation (EU) Nos 16351/12 (Agreement on a Unified Patent Court), 1257/2012 and 1260/2012 and its applicable Annexes and Rules of Procedure, as amended and from time-to-time in effect (the “UPC”), and shall be solely responsible for all costs and expenses it incurs in connection with such opt-in and opt-out. If Shire has expressly opted out of (and not subsequently opted back in to) the EU Unitary Patent System with respect to a given Joint Patent Right that does not claim the composition, manufacture or use of a ZF Compound or product or method containing, employing or made using a ZF Compound or a Shire [***] Patent Right, Sangamo shall not initiate any action to enforce any such Patent Right under the EU Unitary Patent System without Shire’s prior written approval. Without limitation of Sangamo’s rights under Section 11.4, Sangamo shall, following consultation with Shire and good faith consideration of Shire’s comments, have the exclusive right to opt-in and opt-out all Sangamo Patent Rights and all Joint Patent Rights that claim the composition, manufacture or use of any ZF Compound or product or method containing, employing or made using a ZF Compound (unless any such Patent Right is a unitary European patent) from the jurisdiction of the UPC, and shall be solely responsible for all costs and expenses it incurs in connection with such opt-in and opt-out. If Sangamo has expressly opted out of (and not subsequently opted in to) the EU Unitary Patent System with respect to a given Joint Patent Right that claims the composition, manufacture or use of a ZF Compound or product or method containing, employing or made using a ZF Compound, or Sangamo Patent Right or Shire Patent Right, Shire shall not initiate any action to enforce any such Patent Right under the EU Unitary Patent System without Sangamo’s prior written approval. Each Party shall cooperate with the other Party to the extent reasonably requested by such Party to effectuate the intent of this Section 11.3(f).

(a) Existing Third Party Licenses. Sangamo shall be solely responsible for [***], except as provided in Section 10.2 and Section 10.3.

(b) New Third Party Licenses. Schedule 11.4(b) sets forth all license agreements with Third Parties entered into by Sangamo after the Effective Date and prior to the Amendment Effective Date pursuant to which Sangamo received a license under any Patent Rights or Know-How necessary or useful for the development, manufacture or commercialization of any Shire ZF Compound or Shire ZF Product. Shire will have the option to be granted a sublicense pursuant to Section 8.1 under such scheduled license agreements as well as any license agreement with a Third Party entered into by Sangamo after the Amendment Effective Date pursuant to which Sangamo receives a sublicensable license under any Patent Rights or Know-How necessary for the development, manufacture or commercialization of any Shire ZF Compound or Shire ZF Product. If Shire elects to be granted such a sublicense by Sangamo, then Shire must agree to (i) pay to Sangamo [***], (ii) provide all reports required under the agreement with such Third

Party licensor on account of Sangamo’s exercise of such license, (iii) assume all obligations of a sublicensee under such Third Party agreement, and must acknowledge in writing that its sublicense is subject to the terms and conditions of such Third Party agreement. Only upon agreeing in writing to make such payments and fulfill such other obligations will such license agreement become a Third Party License for the purposes of this Agreement and such Patent Rights or Know-How licensed under such license agreement be Controlled by Sangamo for the purposes of this Agreement. Notwithstanding anything in this Agreement to the contrary, in the event of a Change of Control of Sangamo, the provisions of this Section 11.4(b) will not apply to any license agreements entered into by the Third Party acquiror prior to the effective date of such Change of Control. Accordingly, (A) no such license agreements entered into by such Third Party acquiror will become Third Party Licenses for the purposes of this Agreement, and (B) no Patent Rights or Know-How licensed under such license agreements will be Controlled by Sangamo for purposes of this Agreement.

(c) [***]. Sangamo will use Commercially Reasonable Efforts to [***] that is substantially similar in substance the form of [***]. If Sangamo fails to enter into such an [***], Sangamo shall ensure that such jointly invented [***].

(e) Third Party Infringement Suit. Subject to a Party’s obligations to indemnify and defend the other Party pursuant to Article 13, if a Third Party sues a Party or any of such Party’s Affiliates or any Sublicensees (each Person so sued a “Sued Party”) alleging that the Sued Party’s development, manufacture or commercialization of a Collaboration ZF Product infringed or will infringe such Third Party’s intellectual property rights, upon the Sued Party’s request and in connection with the Sued Party’s defense of any such Third Party infringement suit, the other Party shall provide reasonable assistance to the Sued Party for such defense, at the Sued Party’s expense.

(a) Shire’s Rights. If a Third Party brings a declaratory judgment suit against Shire with respect to Joint Patent Rights that do not claim the composition, manufacture or use of a ZF Compound or a product or method containing, employing or made using a ZF Compound, or Shire [***] Patent Rights or any other Patent Rights owned or Controlled by Shire (other than a Shire Patent Right if such suit is also brought against Sangamo and is related to a Sangamo ZF Product Infringement), then Shire shall have the sole right, but not the obligation, to control the defense of such suit. Sangamo shall cooperate with Shire in any such suit as reasonably requested by Shire and at Shire’s expense. If the suit involves any such Joint Patent Right or any Shire [***] Patent Right, then Sangamo also shall have the right to consult with Shire, and to participate in and be represented by independent counsel in such litigation at its own expense. Shire shall not, without Sangamo’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Sangamo or admits the invalidity or unenforceability of any Joint Patent Rights or Shire [***] Patent Rights, which consent shall not be unreasonably withheld, conditioned or delayed.

(b) Sangamo’s Rights. If a Third Party brings a declaratory judgment suit against Sangamo respecting the Joint Patent Rights that claim the composition, manufacture or use of a ZF Compound or product or method containing, employing or made using a ZF Compound or any Sangamo Patent Rights or Shire Patent Rights (solely to the extent related to a Sangamo ZF Product Infringement), then Sangamo shall have the sole right, but not the obligation, to control the defense of such suit. Shire shall cooperate with Sangamo in any such suit as reasonably requested by Sangamo and at Sangamo’s expense, and Shire shall have the right to consult with Sangamo and to participate in and, if appropriate, be represented by independent counsel in such litigation at its own expense in the event the loss of such Patent Rights would adversely impact Shire’s Net Sales, or market share, of a Shire ZF Product. Sangamo shall not, without Shire’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Shire or admits the invalidity or unenforceability of any Sangamo Patent Rights, Shire Patent Rights or Joint Patent Rights, which consent shall not be unreasonably withheld, conditioned or delayed.

(c) Other Rights. If a Third Party brings a declaratory judgment suit against Shire with respect to Sangamo Patent Rights, then Sangamo shall have the first right, but not the obligation, to control the defense of such suit with respect to such Sangamo Patent Rights.

Shire shall have the right to consult with Sangamo and to participate in and be represented by independent counsel in such litigation at its own expense. Sangamo shall not, without Shire’s prior written consent, enter into any settlement or consent decree that requires any payment by or admits or imparts any other liability to Shire or admits the invalidity or unenforceability of any Sangamo Patent Rights, which consent shall not be unreasonably withheld, conditioned or delayed. If Sangamo informs Shire that Sangamo does not intend to exercise its first right to control the defense of such suit, then Shire shall control the defense of such suit and Sangamo shall cooperate with Shire in any such suit as reasonably requested by Shire and at Shire’s expense. With respect to such Sangamo Patent Rights, Sangamo shall have the right to consult with Shire and to participate in and be represented by independent counsel in such litigation at its own expense.

11.6 Interference, Opposition, Revocation and Declaratory Judgment Actions by Parties. If the Parties mutually determine that, based upon the review of a Third Party’s patent or patent application or other intellectual property rights and subject to applicable laws and regulations, it may be desirable in connection with [***] to provoke or institute an interference, opposition, revocation or declaratory judgment action with respect thereto, then the Parties shall consult with one another and shall reasonably cooperate in connection with such an action. Unless otherwise agreed to by the Parties, if the Third Party patent or patent application Covers a Shire Target or the making, using or selling in the Field of a Shire ZF Compound or Shire ZF Product, then in connection with an opposition, revocation or declaratory judgment action Shire may, at its discretion, control such action and select counsel for such action. Shire shall be responsible for, and shall bear, all the out-of-pocket expenses of any such action brought by Shire. If the Third Party patent or patent application is otherwise directed to [***] may, at its discretion, control such action and select counsel for such action.

Unless otherwise agreed to by the Parties, in connection with an interference, the Party responsible for prosecuting the patent application involved in the interference may, at its discretion, control such action and select counsel for such action, and shall be responsible for and bear all the out-of-pocket expenses of, any such action. The prosecuting Party shall consider in good faith, take into account and implement where possible the reasonable comments made by the non-prosecuting Party.

12.1 Confidentiality. During the Term and for [***] years thereafter, each Party shall maintain in confidence the Confidential Information of the other Party, shall not use or grant the use of the Confidential Information of the other Party except as expressly permitted under this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder), and shall not disclose the Confidential Information of the other Party except on a need-to-know basis to such Party’s directors, officers and employees, and to such Party’s consultants working on such Party’s premises or Subcontractors, to the extent such disclosure is necessary in connection with such Party’s activities as expressly authorized by this Agreement. To the extent that disclosure to any Person is authorized by this Agreement (including Subcontractors as described in Section 3.6), prior to disclosure, a Party shall obtain, or shall have obtained prior to the date of this Agreement, written agreement of such Person to hold in confidence and not disclose, use or grant the use of the Confidential Information of the other Party except as expressly permitted under this Agreement. Each Party shall notify the other Party promptly upon discovery of any unauthorized use or disclosure of the other Party’s Confidential Information.

Shire acknowledges that the licensors of all Existing Third Party Licenses are bound by confidentiality obligations reasonably acceptable to Shire.

12.3 Permitted Disclosures.

13.2 Shire. Shire shall indemnify, defend and hold harmless Sangamo and its Affiliates, and each of its respective directors, officers, employees and agents (collectively “Sangamo Indemnified Party”), 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 Shire under this Agreement; (b) the practice of the licenses granted by Sangamo or the development, clinical testing, manufacture, use, handling, storage, distribution, marketing, promotion or sale of Shire ZF Compounds or Shire ZF Products by Shire, its Affiliates or Sublicensees (including any such Liabilities arising out or alleged to arise out of any Shire ZF Product manufactured, sold or distributed by or for Shire, its Affiliates or Sublicensees or any violation of law by Shire, its Affiliates or Sublicensees); (c) the development, clinical testing, manufacture, use, handling, storage, distribution, marketing, promotion or sale of any ZF Compound or ZF Product by Shire, its Affiliates or licensees, as licensed or granted to Shire pursuant to Section 15.5(e) (including any such Liabilities arising out of or alleged to arise out of any such ZF Compound or ZF Product manufactured, sold or distributed by or for Shire, its Affiliates or licensees or any violation of law by Shire, its Affiliates or licensees); (d) any claim of infringement or misappropriation of Third Party intellectual property rights with respect to performance of the Research Program in accordance with a Research Plan; or (e) the recklessness, negligence or intentional misconduct of any Shire Indemnified Party; except,

13.3 Procedure. If a Party (the “Indemnitee”) intends to claim indemnification under this Article 13, it shall promptly notify the other Party (the “Indemnitor”) in writing of any claim, demand, action or other proceeding for which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel of its choice, which counsel shall be reasonably acceptable to the Indemnitee; provided that an Indemnitee shall have the right to retain its own counsel at its expense. Further, the obligations of this Article 13 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of the Indemnitor, which consent shall not be unreasonably withheld, conditioned or delayed. The Indemnitor shall not settle any claim, demand, action or other proceeding without the prior written consent of the Indemnitee, not to be unreasonably withheld, conditioned or delayed unless the settlement involves only the payment of money. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, to the extent prejudicial to its ability to defend such action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Article 13. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by this Article 13.

(a) Shire. During the Research Term and for a tail period [***] thereafter, and for so long as Shire develops or sells Shire ZF Products anywhere in the world and for a tail period [***] thereafter, Shire shall, at its expense, maintain (i) comprehensive General Liability insurance covering death and bodily injury and property damage, with limits of [***], which policy shall include blanket contractual liability applicable to this Agreement; (ii) Product Liability insurance, with limits of [***]; and (iii) Workers’ Compensation insurance including Employers Liability limit of not less than [***] per accident or disease.

Each Party shall provide the other Party with written notice at least 30 days prior to the cancellation, non-renewal or material change in such insurance or self-insurance which materially adversely affect the rights of the other Party hereunder.

15.1 Term. Unless earlier terminated as provided herein, the term of this Agreement shall commence on the Amendment Effective Date and shall continue until such time as all payment obligations with respect to all Collaboration ZF Products expire (the “Term”).

15.2 Termination for Breach. A Party’s material breach of this Agreement shall entitle the non-breaching Party to give to the breaching Party notice specifying the nature of the material breach, requiring it to make good or otherwise cure such material breach, and stating its intention to terminate if such material breach is not cured. If such material breach is not cured within [***] after the receipt of such notice (or within [***] after the receipt of such notice in the event such material breach is solely based upon a Party’s failure to pay any amounts due hereunder), the non-breaching Party shall be entitled, without prejudice to any of its other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement in its entirety or with respect to the other Party’s Target to which the material breach relates; provided that any right to terminate under this Section 15.2 shall be stayed in the event that, during such cure period, the Party alleged to have been in material breach shall have initiated dispute resolution in good faith in accordance with Section 16.2 with respect to the alleged material breach, which stay shall last so long as the initiating Party diligently and in good faith cooperates in the prompt resolution of such dispute resolution proceedings. Notwithstanding the foregoing, Sangamo may not terminate this Agreement as to any particular Shire Target due to a material breach by Shire respecting a different Shire Target, and Shire may not terminate this Agreement as to any particular Sangamo Target due to a material breach by Sangamo respecting a different Sangamo Target.

15.3 Termination for Insolvency. This Agreement may be terminated by either Party upon notice to the other should the other Party: (a) consent to the appointment of a receiver or a general assignment for the benefit of creditors or (b) file or consent to the filing of a petition under any bankruptcy or insolvency law or have any such petition filed against it which has not been stayed within [***] of such filing.

15.4 Termination by Shire for Convenience. Shire may terminate this Agreement in its entirety (which will halt all of the Shire Programs) or with respect to any particular Shire Target (which will halt just the Shire Program that relates to such Terminated Target), in each case effective upon at least [***] prior written notice to Sangamo.

16.12 Construction. This Agreement was negotiated and executed in English, and the original language version shall be controlling; all communications and notices hereunder shall be in English. The Parties acknowledge that they have both had the opportunity to negotiate regarding any issues in connection with this Agreement that were of concern to them and, therefore, expressly waive the benefit of any presumption that ambiguities should be construed in favor of or against either Party. Except where the context otherwise requires, the use of any gender herein shall be deemed to be or include the other genders, the use of the singular shall be deemed to include the plural (and vice versa) and the word “or” is used in the inclusive sense commonly associated with the term “and/or”.

All remedies of either Party hereunder will be cumulative and the pursuit of one remedy will not be deemed a waiver of any other remedy.

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

IN WITNESS WHEREOF, the Parties have caused this Agreement to be executed by their respective duly authorized officers as of the day and year first above written.
