Lilly shall pay the applicable Target Nomination Fee for each Target that Lilly selects to be included as an Additional Target.

3.3.1Target Replacement. On a Collaboration Target-by-Collaboration Target basis, during the period beginning on the Effective Date and ending on the earlier of (a) [***] following Lilly’s receipt of the IND Enabled Data Package for the Licensed Product Directed Against such Collaboration Target in accordance with the applicable Research Plan and (b) the [***] of the expiration of the Target Nomination Period (or, if applicable, the Extended Target Nomination Period), Lilly shall have the right, subject to the terms and conditions of this Agreement, to replace up to two (2) Collaboration Targets (whether Lead Targets or Additional Targets) with a replacement Target (each, a “Replacement Target”) if Lilly determines in good faith, either [***]; provided, that Unavailable Targets shall not be eligible to be selected by Lilly as Replacement Targets. Lilly may exercise such right in its sole discretion by providing written notice to Precision, through the JSC, specifying the identity of the Target that Lilly desires to include as a Collaboration Target under this Agreement (the “Proposed Replacement Target”) (which, for avoidance of doubt, may include an Independently Developed Target, subject to Section 3.4) as well as the Collaboration Target to be replaced (a “Replacement Request”). If the Proposed Replacement Target is an Unavailable Target at the time Precision receives such Replacement Request, then

Precision shall within [***] of receipt of the Replacement Request (the “Replacement Availability Notice Period”) provide written notice to Lilly that the Proposed Replacement Target is an Unavailable Target, and such Replacement Request shall have no further effect. If the Proposed Replacement Target specified in such Replacement Request is not an Unavailable Target, then the replaced Collaboration Target will be deemed an Unavailable Target and not a Collaboration Target, and the Proposed Replacement Target will be deemed a Collaboration Target, upon receipt of such Replacement Request by Precision. For avoidance of doubt, a Replacement Target that replaces a Collaboration Target may itself be eligible to be replaced by a Replacement Target in accordance with this Section 3.3.1, provided Lilly has not already exhausted its two (2) replacements.

As consideration for adding a Target as a Replacement Target, Lilly shall pay to Precision a one-time fee (the “Replacement Fee”) of [***] within [***] following expiration of the Replacement Availability Notice Period following Lilly’s delivery to Precision of the Replacement Request that resulted in such Target becoming a Replacement Target; provided, that if [***], provided further, that if [***]. Lilly shall pay the applicable Replacement Fee for each Target that Lilly selects to be included as a Replacement Target.

3.4Precision Independently Developed Targets. During the Target Nomination Period and continuing through the Extended Target Nomination Period, if applicable, and provided Lilly has not already named three (3) Additional Targets, if Precision initiates internal pre-clinical development (i.e., initiates any studies in vivo) of an in vivo gene editing product Directed Against a Target other than a Collaboration Target or Unavailable Target (an “Independently Developed Target”), Precision shall promptly notify Lilly, via the JSC, upon initiation of such work on the Independently Developed Target. Precision shall thereafter [***] for a period of [***]. If Lilly does not elect to deliver a Nomination Request pursuant to Section 3.2.1 or Replacement Request pursuant to Section 3.3.1 (if applicable) specifying the Independently Developed Target as an Additional Target or Replacement Target prior to [***], [***]. Following such notification, and provided that such Independently Developed Target has not become an Unavailable Target, Precision shall provide Lilly, via the JSC, periodic status updates, including summarizing preclinical research results regarding such in vivo gene-editing product Directed Against such Independently Developed Target through the first small animal proof-of-concept study (or the first large animal proof-of-concept study, if initiated without prior small animal proof-of-concept) (a “PC POC Study”), which updates shall be reasonably sufficient (subject to available information) to enable Lilly to determine whether to include the Independently Developed Target as an Additional Target or Replacement Target. Subject to the terms and conditions of this Agreement, at any time prior to the date that is [***] following the date on which the results of the PC POC Study are delivered to Lilly (the “IDT Nomination Period”), Lilly may, in its sole discretion, elect to deliver a Nomination Request pursuant to Section 3.2.1 or Replacement Request pursuant to Section 3.3.1 (if applicable) specifying the Independently Developed Target as an Additional Target or Replacement Target. If the Independently Developed Target becomes an Additional Target pursuant to Section 3.2.1 or Replacement Target pursuant to Section 3.3.1, if applicable, then such Target shall be deemed a Collaboration Target and not an Independently Developed Target, and Lilly shall pay the applicable Target Nomination Fee pursuant to Section 3.2.2 or Replacement Fee pursuant to Section 3.3.2. If such Independently Developed Target does not become an Additional Target or

Replacement Target prior to the expiration of the IDT Nomination Period, then upon such expiration, Lilly shall have no further rights to such Independently Developed Target and such Independently Developed Target will be deemed an Unavailable Target. Upon the expiration of the Target Nomination Period (or, if applicable, the Extended Target Nomination Period) or once Lilly has named three (3) Additional Targets (whichever occurs first), Precision’s obligations under this Section 3.4 with respect to any Independently Developed Targets shall cease to apply, and all then-existing Independently Developed Targets and any Independently Developed Targets for which Precision thereafter initiates internal pre-clinical development will be deemed Unavailable Targets and not eligible to be named as Replacement Targets. As of the Execution Date, Targets (for avoidance of doubt, other than the Lead Targets and Reserved Targets) with respect to which Precision has already completed a PC POC Study are listed on Exhibit 3.4 attached hereto, and are additionally deemed Unavailable Targets [***].

3.5Reserved Targets. During the period beginning on the Effective Date and ending on (a) the earliest to occur of [***] in the case of [***], and (b) on the [***], in the case of [***] (each period, with respect to the applicable Reserved Target, the “Reserved Target Period”), Lilly may name a Reserved Target as an Additional Target or Replacement Target, if applicable. During the applicable Reserved Target Period: (x) Precision will provide quarterly updates to Lilly regarding Precision’s development efforts (if any) with respect to each Reserved Target, including updates on clinical trials of compounds directed to such Reserved Targets as data from such trials becomes available; and (y) the Reserved Target shall not be considered an Unavailable Target. If a Reserved Target is not named by Lilly as an Additional Target or Replacement Target during the applicable Reserved Target Period, then from and after the expiration of such Reserved Target Period, such Reserved Target will be deemed an Unavailable Target and not a Reserved Target. Notwithstanding the foregoing, in the case of [***], if the Reserved Target Period expires on the [***] of the Effective Date pursuant to Section 3.5(a)(i), [***] shall cease to be a Reserved Target upon expiration of the Reserved Target Period but shall not be deemed to be an Unavailable Target as a result of such expiration.

3.8Unavailable Targets. Promptly following the Effective Date, the Parties shall agree upon an independent Third Party to serve as an escrow agent for purposes of this Section 3.8 (the “Escrow Agent”). Following agreement on the Escrow Agent, if any Target becomes or has become an Unavailable Target after the Effective Date, Precision shall submit a complete and accurate list of Unavailable Targets along with a copy of the applicable agreement, term sheet, or letter of intent related to each of such Unavailable Targets, which copies may be submitted in redacted form (the “Unavailable Target Information”), to the Escrow Agent, and shall provide the Escrow Agent with updated Unavailable Target Information promptly upon any Target becoming an Unavailable Target or losing its status as an Unavailable Target. Unavailable Target Information shall be held by the Escrow Agent in confidence. If Lilly delivers a Nomination Request pursuant to Section 3.2.1 or Replacement Request pursuant to Section 3.3.1 that specifies an Unavailable Target, then by written notice to Precision and to the Escrow Agent, Lilly may require the Escrow Agent to confirm to Lilly that such Target is an Unavailable Target. In response to a particular Nomination Request or Replacement Request, the Escrow

Agent shall not provide to Lilly the identity of any other Target that appears on the list of Unavailable Targets or any details regarding any agreement (draft of otherwise), term sheet or letter of intent related to any Unavailable Target, other than such confirmation.

3.9Reservation of Rights. Precision will be free to grant rights for any Target that is not a Lead Target, Additional Target or Reserved Target (including any Independently Developed Target [***] or Unavailable Target) to any Third Party at any time.

All

Precision Materials will at all times remain the property of Precision and will be held confidential in respect to Third Parties and will not be transferred to a Third Party (other than a Sublicensee or a subcontractor engaged in accordance with Section 4.9) without prior written permission of Precision. Upon the termination of this Agreement, Lilly will, at Precision’s sole discretion and Lilly’s cost, either (a) dispose of any residual Precision Materials not consumed by Lilly in the performance of this Agreement in accordance with Applicable Laws, or (b) upon request, return such Precision Materials to Precision. Any such materials provided to Lilly by Precision shall be accompanied by a Materials Transfer Record.

5.1Clinical Development Responsibilities. Lilly shall lead, and have sole responsibility and control for, the Clinical Development of all Licensed Products, including the determination of whether to file an IND with respect to any Licensed Product and for preparation and submission of the IND filing for each Licensed Product. Subject to the terms of this Agreement, all decisions concerning the Clinical Development of Licensed Products, including the clinical and regulatory strategy of Licensed Products covered under this Agreement, shall be within the sole discretion of Lilly. Except if Precision exercises its option to co-fund Clinical Development of a Licensed Product pursuant to Section 5.3 below (in which case Section 5.3 shall apply), Lilly shall be solely responsible (as between the Parties) for all costs and expenses of Clinical Development. Upon request of either Party, the Parties shall negotiate and agree on any additional agreements necessary for the Clinical Development of Licensed Products. Following the Effective Date, and until the date which is [***], Precision shall, on a Calendar Quarterly basis, share with Lilly, through the JSC, [***].

5.2Diligence Efforts. Lilly shall use Commercially Reasonable Efforts to Clinically Develop each Licensed Product [***], in accordance with a commercially reasonable development plan prepared by Lilly. However, if Lilly elects, in its sole discretion, to cease Clinical Development of a Licensed Product [***], then the applicable Collaboration Target for such Licensed Product will cease to be a Collaboration Target and the Licensed Product will be deemed a Terminated Product, and all rights in such Terminated Product shall revert to Precision in accordance with Section 15.5.3.

5.3.1Provided that two (2) Licensed Products have advanced to submission of an IND filing, Precision shall have a one-time option, exercisable at any time prior to the anticipated date of submission of an IND filing for a subsequent Licensed Product (such date as set forth in the applicable Research Plan), to elect to co-fund the Clinical Development of a single such subsequent Licensed Product with Lilly. Precision may indicate its interest to exercise such option by providing Lilly with [***] written notice (the “Co-Funding Option Interest Notice” with respect to such Licensed Product) in advance of the anticipated IND filing; provided, however, if Lilly has not yet elected to pursue Clinical Development with respect to such Licensed Product by such date, Precision may indicate such interest by providing a Co-Funding Option Interest Notice

within [***] of Lilly’s election. Upon delivery of the Co-Funding Option Interest Notice, the applicable Licensed Product shall, in addition to its status as a Licensed Product, be deemed a prospective “Co-Funded Product”.

5.3.2Within [***] of receipt of the Co-Funding Option Interest Notice with respect to a prospective Co-Funded Product, Lilly shall provide Precision with a copy of Lilly’s then-current, internal plan for Clinical Development (the “Lilly Clinical Development Plan”) therefor. The Lilly Clinical Development Plan shall include, at a minimum, Lilly’s good faith then-current estimates of Clinical Development Expenses and timeline for the conduct of the Clinical Development activities contemplated by such Lilly Clinical Development Plan for such Co-Funded Product, broken down on a Calendar Quarterly basis. Lilly, through the JSC, shall timely answer any of Precision’s reasonable questions relating to such Lilly Clinical Development Plan and shall make available to the JSC, on a Calendar Quarterly basis, a copy of the Lilly Clinical Development Plan, and any updates or amendments thereto, and anticipated Clinical Development Expenses to be incurred in the upcoming Calendar Quarters.

If Precision does not deliver a Co-Funding Option Exercise Notice within such [***] period, such Licensed Product shall cease to be considered a prospective Co-Funded Product and Precision shall have no further rights under this Section 5.3 with respect to such Licensed Product. For clarity, Precision may only exercise the foregoing right to co-fund a Licensed Product one time, regardless of any later termination of Precision’s co-funding commitment under Section 5.3.6, with respect to only one (1) Licensed Product, and such option to co-fund Clinical Development shall not apply to the first two (2) Licensed Products to advance to submission of an IND filing.

5.3.3Notwithstanding any co-funding by Precision, Lilly will at all times continue to have sole control and responsibility for the Clinical Development of any Co-Funded Product.

5.3.4If Precision so elects to co-fund the Clinical Development of a Co-Funded Product (as provided above), then following the full exercise of such right, (i) the Parties will share Clinical Development Expenses incurred thereafter for such Co-Funded Product, with Precision being responsible for [***] of such Clinical Development Expenses and Lilly being responsible for [***] of such Clinical Development Expenses; and (ii) thereafter the royalties owed by Lilly to Precision for such Co-Funded Product will be automatically increased by [***] for each Royalty tier. Lilly shall invoice Precision for reimbursement of Precision's co-funding share on a quarterly basis in arrears, within [***] following the end of the Calendar Quarter in which the relevant expenses were incurred. Precision shall then have [***] after its receipt of such invoice to review such invoice and raise any disputed amounts to Lilly. If Precision does not dispute any amounts payable under an applicable invoice during such period, then Precision shall pay

the amounts payable under any such invoice in arrears and within [***] following such [***] review period (i.e., [***] after its receipt of such invoice).

5.3.5For the duration of Precision’s co-funding commitment, and for a period of [***] thereafter, Lilly shall maintain, and shall cause its Affiliates to maintain, complete and accurate records regarding the co-funded Clinical Development Expenses invoiced by Lilly. Precision shall have the right to have a “Big 4” accounting firm (i.e., KPMG, PwC, Deloitte or Ernst & Young), designated by Lilly and approved by Precision, such approval not to be unreasonably withheld, inspect Lilly’s records for the purpose of determining the accuracy of such expenses in accordance with Section 9.7 applied mutatis mutandis (subject to appropriate changes related to the subject matter of the audit).

5.3.6Precision may terminate its co-funding commitment for a Co-Funded Product upon delivery of written notice to Lilly, specifying in such notice that Precision is terminating its co-funding commitment, with such termination being effective as of midnight New York, NY time on the last day of the Calendar Quarter following the [***] of the date on which such written notice was received by Lilly in accordance with Section 17.4; provided, that (i) Precision shall not be released of its obligation to share Clinical Development Expenses associated with any Clinical Trials with respect to which [***], and (ii) effective immediately upon Precision’s provision of such notice to Lilly, [***]. Upon the effective date of termination of Precision’s co-funding commitment, the applicable Co-Funded Product shall cease to be a Co-Funded Product and the adjusted royalties set forth in Section 5.3.4 will no longer apply.

Subject to the terms and conditions of this Agreement, Lilly hereby grants to Precision a fully paid, royalty-free, non-sub-licensable (except to Third Party subcontractors acting on its behalf, as permitted by Section 4.9), non-exclusive license under the Lilly Background IP and Lilly Collaboration IP (in each case, excluding any Excluded Technology other than as specified in a Supply Agreement), in the Territory solely as and to the extent necessary for Precision or its Affiliates (or Third Party subcontractors) to (a) conduct Research and Pre-Clinical Development pursuant to the Research Plans during the Research Term or (b) Manufacture the Licensed Product pursuant to Sections 6.3.1(a), (b) or (c).

7.3Third Party Sublicenses. Lilly and Precision may grant one or more sublicenses under the rights and licenses granted to it under Section 7.1 (in the case of Lilly) or Section 7.2 (in the case of Precision), in full or in part, to Third Parties (with the right to sublicense through multiple tiers); provided, that: (a) any such permitted sublicense is consistent with and subject to the terms and conditions of this Agreement, including the confidentiality provisions of Article 14 and the intellectual property provisions of Article 11; and (b) the Party granting such sublicense shall remain responsible for performance of such Party’s obligations under this Agreement and shall be responsible for all actions of each such sublicensee as if such sublicensee were the Party hereunder. Notwithstanding the foregoing, during the Research Term with respect to a given Collaboration Target, Lilly shall not grant any sublicenses to a Third Party (other than a consultant or contractor engaged for such activities in accordance with Section 12.3.1) with respect to any Research or Development of a Licensed Product Directed Against such Collaboration Target without Precision’s prior written consent. Each Party shall ensure that each sublicense under the licenses granted to it under Section 7.1 (in the case of Lilly) or Section 7.2

(in the case of Precision) grants the other Party rights with respect to Inventions discovered, created, conceived or reduced to practice by the Sublicensee under such sublicense as if such Inventions were discovered, created, conceived or reduced to practice by the sublicensing Party in the course of performing activities under this Agreement (with the exception of improvements to the Sublicensee’s background technology that are unrelated to the intellectual property that is the subject of this Agreement). In addition, to the extent required by the Cellectis Agreement, each sublicense granted by Lilly under any Patents within Precision Product IP must grant the same scope of rights for all Patents within Precision Product IP and each sublicense granted by Lilly under any Patents within Precision Platform IP must grant the same scope of rights for all Patents within Precision Platform IP. Lilly shall provide Precision with prompt written notice of any grant of sublicense to a Sublicensee of the rights and licenses granted to Lilly under Section 7.1 (but excluding any sublicenses solely for the distribution, marketing or promotion of Licensed Products).

7.4Retention of Rights; No Implied Rights. Subject to the terms and conditions of this Agreement, Lilly agrees that Precision may: (a) practice the Precision Product IP to exercise its rights and perform its obligations under this Agreement or a Supply Agreement; (b) conduct research related to the ARCUS Technology; and (c) practice and license the Precision Product IP outside the scope of the license granted to Lilly under Section 7.1.1. Except as expressly set forth in this Agreement, neither Party shall be granted, by implication, estoppel or otherwise, any license or right to or under any other intellectual property interest, including any trademarks, Know-How, or Patents, of the other Party.

7.5Safe Harbor Research. Notwithstanding anything to the contrary in this Agreement, by entering into this Agreement, neither Party is forfeiting any rights that such Party may have to perform research activities in compliance with 35 U.S.C. § 271(e)(1) or any experimental or research use exemption that may apply under Applicable Law or in any country.

7.6.1Cellectis Patents. Lilly acknowledges and agrees that rights under certain Precision Patents are licensed to Precision by Cellectis S.A. (the “Cellectis Patents”) under that certain Patent Cross-License Agreement between Cellectis S.A. and Precision dated January 23, 2014 (the “Cellectis Agreement”), and, notwithstanding any exclusive license granted to Lilly under this Agreement, (a) Cellectis S.A. retains rights under the Cellectis Patents and is not restricted from granting rights to Third Parties under the Cellectis Patents, (b) any licenses and rights granted by Precision to Lilly under the Cellectis Patents are granted only within the permissible scope of sublicenses granted under the Cellectis Agreement, and (c) pursuant to the Cellectis Agreement, Cellectis S.A. retains non-exclusive rights under certain Precision Patents identified in the Cellectis Agreement, which may be further sublicensed by Cellectis S.A. without Precision control or consent. Lilly acknowledges and agrees that any exercise of any right by Cellectis S.A, or by any Third Party through Cellectis S.A, under the Cellectis Agreement shall not constitute a breach of this Agreement by Precision.

7.6.2Duke IP. Lilly acknowledges and agrees that any licenses and rights granted by Precision to Lilly under the Duke IP are granted subject to the terms and

conditions of the Duke Agreement, including Duke’s right to practice under the Duke IP for its own internal, non-commercial, educational, research and clinical purposes, and subject to the rights of the United States Government and applicable limitations under 37 C.F.R. § 401, Public Law 96-517 and Public Law 98-620 resulting from the United States Government’s funding of research leading to creation of the Duke IP. Without limiting the foregoing, Lilly agrees to comply with any obligations resulting from such government rights with respect to its practice of the Duke IP (if any) under this Agreement.

7.7Preservation of Existing In-License Agreements. To the extent relating to the Licensed Products, Precision shall, and shall procure that its Affiliates shall, (a) maintain the Existing In-License Agreements in full force and effect in accordance with their terms and conditions and keep Lilly reasonably informed in this regard and (b) promptly provide notice to Lilly in the event any disputes arise under the Existing In-License Agreements or in the event Precision receives any notices from Duke or Cellectis under such parties’ respective Existing In-License Agreement which concern the Duke IP or Cellectis Patents or rights with respect thereto. Without limiting the foregoing and Section 9.5, Precision shall not (x) commit any acts or permit the occurrence of any omissions that could reasonably be expected to cause breach or termination of the Existing In-License Agreements or (y) amend or otherwise modify or permit to be amended or modified, the Existing In-License Agreements, in any way that would prejudice Lilly’s rights under this Agreement or its ability to continue to Research, Develop, Manufacture, make, have made, use, keep, import, export, offer for sale, sell, Commercialize, or otherwise exploit Licensed Products. In the event any Existing In-License Agreement is terminated, the Parties agree that Lilly may offset from the amounts due to Precision under this Agreement any amounts Lilly is required to pay to the applicable counterparty for the licenses covered by such terminated Existing In-License Agreement (or, in the event Lilly cannot offset such amounts against payments due to Precision for any reason, Precision shall promptly reimburse Lilly for all such amounts.)

7.8Consideration. The Parties acknowledge that each of the licenses and rights granted by Precision in this Agreement and each of the provisions of this Agreement for efforts or assistance by Precision and access to Precision Technology, individually and collectively, constitute good, valuable and sufficient consideration for each and all of the fees and payments called for hereunder and for each and all of the other obligations of Lilly, its Affiliates and its and their Sublicensees; and the Parties further acknowledge that the individual and collective rights under and access to Precision Technology renders the way in which those fees and payments hereunder are determined, their amount (and potential reduction) and their duration, appropriate and desirable as a matter of convenience.

8.1Lilly Exclusivity Obligations. During the period commencing on the Effective Date and [***], except for Lilly’s conduct of any Research, Development, Manufacturing or Commercialization activities under this Agreement or a Supply Agreement, neither Lilly nor [***] shall, directly or indirectly [***].

8.2Precision Exclusivity Obligations. During the Term of this Agreement, except for Precision’s conduct of any Research, Development or Manufacturing activities under this Agreement or a Supply Agreement, neither Precision nor [***], shall, directly or indirectly [***]. The Parties acknowledge and agree that Precision’s conduct of any Research, Development or Manufacturing activities under this Agreement or a Supply Agreement shall not constitute a breach of this Section 8.2.

8.3.1Acquisition of Existing Competing Program. Notwithstanding the exclusivity obligations set forth in Sections 8.1 or 8.2, if, after the Effective Date, any Third Party becomes [***] as a result of a merger, acquisition, consolidation, asset sale, or other similar transaction (whether in a single transaction or series of related transactions), and, as of the closing date of such transaction, such Third Party is engaged in: (a) [***]; or (b) [***] (such activities in (a) and (b), a “Competing Program”), then continuation of the relevant Competing Program shall not be a breach of this Agreement provided that such Party provides the other Party with written notice of such transaction promptly, but no later than [***], and such Party does (or causes such Affiliate to), within [***], [***].

8.3.2Existing Competing Program of a Precision Acquirer. If after the Effective Date any Third Party becomes an Acquirer of Precision as a result of a Change of Control of Precision, and, as of the closing date of such transaction, such Acquirer is engaged in a Competing Program, then the provisions of Section 17.8 shall apply.

9.1Upfront Payment. As partial consideration for the rights granted by Precision to Lilly pursuant to the terms of this Agreement, Lilly shall pay to Precision a one-time payment equal to One Hundred Million Dollars ($100,000,000) within [***] following the Effective Date.

9.2Equity Investment. As partial consideration for the rights granted by Precision to Lilly pursuant to the terms of this Agreement, as of the Effective Date, the Parties have entered into the Stock Purchase Agreement.

9.3.1On a Licensed Product-by-Licensed Product basis, Lilly shall pay to Precision certain milestone payments, as follows: (a) within [***] following any Licensed Product achieving a development milestone event set forth in Table 9.3 below (each, a “Development Milestone Event”), Lilly shall pay to Precision the corresponding Milestone Payment indicated in Table 9.3 (each such Milestone Payment, a “Development Milestone Payment”); and (b) within [***] following the end of the Calendar Quarter in which any Licensed Product achieves a commercial milestone event set forth in Table 9.3 (each, a “Commercial Milestone Event”), Lilly shall pay to Precision the corresponding Milestone Payment indicated in Table 9.3 (each such Milestone Payment, a “Commercial

Milestone Payment”). The Development Milestone Events and Commercial Milestone Events may be referred to individually or collectively as “Milestone Events”, and Development Milestone Payments and Commercial Milestone Payments may be referred to individually or collectively as “Milestone Payments.” For purposes of determining whether the Net Sales thresholds set forth in Table 9.3 have been achieved for a Licensed Product for purposes of this Section 9.3, all Net Sales of such Licensed Product shall be aggregated globally for all sales made by Lilly or any of its Affiliates or its or their Sublicensees of such Licensed Product, in any and all forms, presentations, dosages, and formulations. For clarity, each Milestone Payment shall be payable only once per Licensed Product, no Milestone Payment shall be payable for subsequent or repeated achievements of the same Milestone Event with respect to the same Licensed Product. [***].

9.3.2The Development Milestone Events for clinical trial Initiation are intended to be sequential. Achievement of a Development Milestone Event relating to dosing of a Clinical Trial patient shall result in deemed achievement of all earlier Development Milestone Events, and achievement of a “First BLA filing” Development Milestone Event shall result in deemed achievement of all Development Milestone Events relating to initiation of toxicology studies or dosing of Clinical Trial patients. Similarly, achievement of each Commercial Milestone Event measured by annual Net Sales shall result in achievement of all Commercial Milestone Events measured by a lower amount of annual Net Sales.

9.3.3In addition to the Development Milestone Payments payable by Lilly for achievement of the Development Milestone Events indicated in Table 9.3, if Lilly or any of its Affiliates or its or their Sublicensees [***], Lilly shall pay to Precision [***]. Any such payment shall be considered a Development Milestone Payment for purposes of this Agreement, and be treated consistently with other Development Milestone Payments, including for purposes of Section 9.5 through and including Section 9.9.

9.4.1Royalty Term. Lilly shall pay Precision royalties as set forth in this Section 9.4 on a Licensed Product-by-Licensed Product and country-by-country basis in the Territory during the period of time beginning on the date of the First Commercial Sale of such Licensed Product in such country and continuing until the latest to occur of: (a) the expiration or abandonment of the last-to-expire Valid Claim in such country Covering such Licensed Product; (b) the expiration of any period of data, regulatory, or market exclusivity, or supplemental protection certificates (other than Patent rights) covering the Licensed Product in such country; and (c) ten (10) years after the First Commercial Sale of such Product in such country (the “Royalty Term”). Upon the expiration of the Royalty Term for a Licensed Product in a particular country, the license granted by Precision to Lilly under (i) Section 7.1.1 with respect to such Licensed Product and such country shall survive and become perpetual, fully-paid, and royalty-free, and shall remain exclusive (even as to Precision and its Affiliates) and (ii) Section 7.1.2 with respect to such Licensed Product and such country shall survive and become perpetual, fully-paid, and royalty-free, and shall remain non-exclusive.

9.4.2Royalty Rates. On a Licensed Product-by-Licensed Product and country-by-country basis, during the Royalty Term, Lilly shall pay to Precision a tiered royalty equal to the percentages of annual global Net Sales of such Licensed Product, as set forth below (the “Royalty”), calculated by multiplying the applicable royalty rate percentage by the corresponding portion of aggregate global Net Sales for such Licensed Product in such Calendar Year. For purposes of determining whether the Net Sales thresholds below in this Section 9.4.2 have been achieved for a Licensed Product for purposes of this Section 9.4.2, all Net Sales of such Licensed Product shall be aggregated globally for all sales made by Lilly or any of its Affiliates or its or their Sublicensees of such Licensed Product, in any and all forms, presentations, dosages, and formulations. For clarity, the incremental royalty rates set forth below will only apply to that portion of the Net Sales of royalty-bearing Licensed Products that fall within the indicated range of sales.

The portion of annual global Net Sales of such Licensed Product greater than [*] but less than or equal to [*]	[***]
The portion of annual global Net Sales of such Licensed Product greater than [***]	[***]

9.4.3Valid Claim. If, at the time a Licensed Product is sold in a country during the Royalty Term for a Licensed Product, there is no longer a Valid Claim of a Precision Patent that Covers such Licensed Product in such country, the Royalty rates provided in Section 9.4.2 above for the sale of such Licensed Product in such country will be reduced in such country by [***].

9.4.4Biosimilar Products. On a country-by-country and Licensed Product-by-Licensed Product basis: (a) upon the first commercial sale of one or more Biosimilar Products with respect to a Licensed Product in any country in the Territory during the Royalty Term, the Royalty rates provided in Section 9.4.2 above for the Licensed Product will be reduced in such country by [***] from the date of first commercial sale of such Biosimilar Product(s) in such country; and (b) [***].

9.4.5Third Party Payments. Lilly may deduct from any Royalty payments to Precision under this Section 9.4 for the sale of a given Licensed Product in a given country (after application of Sections 9.4.3 and 9.4.4) an amount equal to [***] of any (a) royalty payments based on such sale, and (b) Qualifying Non-Royalty Payments, in each case ((a) and (b)) made by Lilly to a Third Party in consideration for a right or license under such Third Party’s interest in any Patents [***] that contain a Valid Claim which Covers the relevant Licensed Product in the Field in the Territory; provided, that in no event will the Royalty payments payable to Precision under this Section 9.4 for each Licensed Product be reduced, as a result of this Section 9.4.5, by more than [***]. For purposes of this Section 9.4.5, “Qualifying Non-Royalty Payments” means [***]. Qualifying Non-Royalty Payments exclude in all cases Clinical Development Expenses set forth in Section 1.30.8 with respect to a Co-Funded Product.

9.4.6Payment; Reports. Royalty payments due by Lilly to Precision under this Section 9.4 will be calculated and reported for each Calendar Quarter. All Royalty payments due under this Section 9.4 shall be paid within [***] after the end of

each Calendar Quarter and shall be accompanied by a report setting forth, with respect to each Calendar Quarter, on a Licensed Product-by-Licensed Product and country-by-country basis: (a) Net Sales of the Licensed Product by Lilly and its Affiliates and Sublicensees in the Territory and (b) a calculation of the Royalties due on such Net Sales.

9.5Payments under Existing In-License Agreements. The Parties acknowledge and agree that Precision shall be solely responsible for, and shall promptly discharge, any and all payments payable pursuant to the Existing In-License Agreements.

9.6Method of Payment; Currency Conversion. Unless otherwise agreed by the Parties, all payments due under this Agreement shall be paid in Dollars by wire transfer or electronic funds transfer of immediately available funds to an account designated by the payee; provided however, that Lilly shall only be required to disburse funds to the payee’s jurisdiction of incorporation or to a jurisdiction in which the payee has a significant business presence. The initial wire transfer instructions for Precision are as set forth on Exhibit 9.6. When conversion of payments from any currency other than Dollars is required, Lilly’s then-current standard exchange rate methodology will be employed for the translation of foreign currency sales into Dollars; provided, that this methodology is used by Lilly in the translation of its foreign currency operating results, is consistent with U.S. GAAP, is audited by Lilly’s independent certified public accountants in connection with the audit of the consolidated financial statements of Lilly, and is used for external reporting of foreign currency operating results.

9.7Records and Audits. Lilly shall keep, and shall cause its Affiliates and Sublicensees to keep, complete and accurate records pertaining to its gross sales and Net Sales of the Licensed Products as necessary to ascertain properly and to verify the Royalty and milestone payments due hereunder. Such records shall be kept for a period of time required by Applicable Laws, but no less than [***] following the end of the Calendar Quarter to which they pertain. Precision shall have the right, but not more than [***], to have a “Big 4” accounting firm (i.e., KPMG, PwC, Deloitte or Ernst & Young), designated by Lilly and approved by Precision, such approval not to be unreasonably withheld, inspect Lilly’s records for the purpose of determining the accuracy of Royalty and milestone payments for a period covering not more than [***] following the Calendar Quarter to which they pertain. No period will be audited more than [***] and each audit must be reasonable in scope. The independent, certified public accountant selected shall keep confidential any information obtained during such inspection and shall report to Precision and Lilly only the amounts of Net Sales and royalties due and payable. Such audits may be exercised during normal business hours upon reasonable prior written notice to Lilly. Precision shall bear the full cost of such audit unless such audit discloses an underpayment by Lilly of more than [***], of the amount of royalties or other payments due under this Agreement for any applicable Calendar Quarter, in which case, Lilly shall bear the cost of such audit and shall remit to Precision the amount of any underpayment within [***] of the date the auditor’s written report is received. Any overpayment by Lilly revealed by an audit shall be credited against future payments owed by Lilly to Precision (and if no further payments are due, shall be refunded by Precision at the request of Lilly within [***] of the receipt of the request).

9.8Late Payments. If any payment properly due under this Agreement and not subject to a good faith dispute is not paid when due in accordance with the applicable provisions of this Agreement, the payment shall accrue interest from the date due at the rate of [***]. The

payment of such interest shall not limit the Party entitled to receive payment from exercising any other rights it may have as a consequence of the lateness of any payment.

9.9.1Cooperation and Coordination. The Parties acknowledge and agree that it is their mutual objective and intent to minimize, to the extent feasible and in compliance with Applicable Laws, taxes payable with respect to their collaborative efforts under this Agreement and that they shall use reasonable efforts to cooperate and coordinate with each other to achieve such objective, including by completing and filing documents required or permitted under the provisions of any Applicable Laws in connection with a claim of exemption from, or entitlement to a reduced rate of, withholding taxes or in connection with any claim to a refund of or credit for any payment of such taxes. Notwithstanding the foregoing, for clarity, it is Precision’s sole responsibility to prepare and file required documents necessary to claim an exemption from withholding tax or to claim a reduced rate of withholding tax, at Precision’s sole expense.

9.9.2Payment of Tax. The upfront, milestones, royalties and other amounts payable by Lilly to Precision to this Agreement (each, a “Payment”) shall be paid free and clear of any and all taxes, except for any withholding taxes required by Applicable Law. Except as provided in this Section 9.9. Precision shall be solely responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be deducted from Payments and remitted by Lilly) levied on account of, or measured in whole or in part by reference to, any Payments it receives. Lilly shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if Precision is entitled under any applicable tax treaty to a reduction in the rate of, or the elimination of, any applicable withholding tax, it may deliver to Lilly or the appropriate Governmental Authority (with the assistance of Lilly to the extent that this is reasonably required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve Lilly of its obligation to withhold such tax and Lilly shall apply the reduced rate of withholding or dispense with withholding as the case may be; provided that Lilly has received Precision’s delivery of all applicable forms in a form satisfactory to Lilly (and, if necessary, evidence, in a form satisfactory to Lilly, of Precision’s receipt of appropriate governmental authorization) at least [***] prior to the time Payments are due. If in accordance with the foregoing, Lilly withholds any amounts of tax, it shall pay to Precision the balance when due, make timely payment to the proper tax authority of the withheld amount and send to Precision proof of such payment within [***] following such payments.

9.9.3Withholding Tax Actions. If Lilly changes its tax residence, performs a tax repatriation or takes any similar action that would increase any required withholding taxes with respect to any Payment that would not be required absent such action, Lilly shall provide Precision with prior written notice to allow Precision a reasonable opportunity to timely furnish forms, certificates or other items that would reduce or eliminate such withholding tax.

10.1HSR Filings. If required by Applicable Laws, promptly after the execution of this Agreement, both Parties shall file (or, if applicable, shall cause their respective Affiliate(s) to file) the appropriate notices with respect to the transactions contemplated hereby as promptly as reasonably practicable with the United States Federal Trade Commission (“FTC”) and Department of Justice (“DOJ”) under the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended (“HSR Act”). Each of the Parties shall promptly supply (or, if applicable, shall cause their respective Affiliate(s) to supply) the other with any information that may reasonably be required in order to effectuate the filings under the HSR Act. Each of the Parties shall notify the other promptly upon receipt from the FTC or DOJ in connection with any filing made under the HSR Act and of any request for amendments or supplements to any such filings or of any communications with, and any other inquiries or requests for additional information from, the FTC and DOJ. Each Party agrees to request, and to cooperate with the other Party in requesting, early termination of any applicable waiting period under the HSR Act. Each Party shall comply (or, if applicable, cause their respective Affiliate(s) to comply) promptly, in accordance with advice received from counsel, as appropriate, with any such inquiry or request. Each Party agrees (and shall cause each of their respective Affiliates) to use their respective commercially reasonable efforts: (a) to cooperate to obtain any authorizations, clearances, orders or approvals required for transactions contemplated hereby under the HSR Act and any other federal, state or foreign Applicable Law, regulation or decree designed to prohibit, restrict or regulate actions intended to or having the effect of reducing competition or monopolizing or restraining trade (collectively, “Antitrust Laws”); (b) to promptly respond to any request by any Governmental Authority for information under any Antitrust Law with respect to the transactions contemplated hereby; (c) to promptly inform the other Party upon receipt of any material communication from the FTC, the DOJ or any other Governmental Authority regarding the transactions contemplated hereby; and (d) subject to applicable legal limitations and the instructions of any Governmental Authority, keep the other Party apprised of the status of matters relating to the transactions contemplated hereby, including promptly furnishing the other Party with copies of material notices or other material communications received by such Party or any of their respective Affiliates, as the case may be, from any Third Party and/or any Governmental Authority with respect to the transactions contemplated hereby. The Parties shall each permit legal counsel for the other Party a reasonable opportunity to review in advance, and consider in good faith the views of the other Party in connection with, any proposed material written communication to any Governmental Authority with respect to the transactions contemplated hereby. Each of the Parties agrees, subject to applicable legal limitations and the instructions of any Governmental Authority, not to participate in any substantive meeting or discussion, either in person or by telephone, with any Governmental Authority in connection with this Agreement unless it consults with the other Party in advance and gives the other Party the opportunity to attend and participate, provided, however, that neither Party shall be required to consent to the divestiture or other disposition of any of its assets or the assets of its Affiliates or to consent to any other structural or conduct remedy and neither Party nor its Affiliates shall have any obligation to contest, administratively or in court, any ruling, order or other action of the FTC or DOJ or any Third Party with respect to the transactions contemplated by this Agreement. Each Party shall be responsible for paying its own costs and expenses (including

legal and consultants’ fees) incurred in connection with obtaining clearance of the transactions contemplated hereby from the FTC and the DOJ, except that Lilly will pay the filing fees incurred by both Parties in connection with the filings required pursuant to the HSR Act. In the event the Parties determine that HSR filings are required, this Agreement (other than Article 10, Article 16 and Section 14.2) shall not be binding until the Closing Date (as defined in the Stock Purchase Agreement) occurs following the HSR Clearance Date (such date, the “Effective Date”) and information exchanged between the Parties shall continue to be subject to the terms of the Confidentiality Agreement. If the Effective Date does not occur prior to the date on which the term of the Confidentiality Agreement would expire, then the term of the Confidentiality Agreement is hereby extended until the earlier of the Effective Date or the date of termination of this Agreement. As used herein, the “HSR Clearance Date” means the earlier of (i) the date on which the FTC or DOJ shall notify the Parties of early termination of the waiting period under the HSR Act or (ii) the date on which the applicable waiting period under the HSR Act expires; provided, however, that if the FTC or DOJ commences any investigation by means of a second request or otherwise, HSR Clearance Date means the date on which any investigation opened by the FTC or DOJ has been terminated, without action to prevent the Parties from implementing the transactions contemplated by this Agreement with respect to the United States. Notwithstanding any other provisions of this Agreement to the contrary, either Party may terminate this Agreement effective upon notice to the other Party if the HSR Clearance Date has not occurred on or before the date that is [***] after the Parties make their respective HSR filings.

10.2Conduct Pending HSR Clearance Date. If the Parties determine that HSR filings are required, (a) between the Execution Date and the earlier of (i) the Effective Date or (ii) the date of termination of this Agreement, each Party shall conduct its business with respect to the intellectual property rights granted hereunder in the ordinary course, and it will refrain from taking any action or omitting to take any action that would have the effect of restricting or impairing the rights to be granted to either Party hereunder or preventing either Party’s ability to perform its obligations under this Agreement, and (b) [***].

10.3Information Rights as of Effective Date. On the Effective Date, Precision shall notify Lilly of any facts or circumstances arising between the Execution Date and the Effective Date that, to Precision’s Knowledge, would result in Precision’s representations and warranties set forth in [***] not being true or correct in all material respects on and as of the Effective Date as though such representations and warranties were made as of and with respect to facts and circumstances existing, to Precision’s Knowledge, as of the Effective Date instead of the Execution Date. For clarity, no such facts or circumstances arising after the Execution Date, and no information provided by Precision to Lilly related to any such facts or circumstances, shall give rise to, or be a basis for, any claim of breach by Lilly of any representations or warranties set forth in [***].

11.1.1Background IP. As between the Parties, and subject to the licenses granted under this Agreement (a) Lilly shall solely own (or retain ownership of) all rights, title and interests in and to the Lilly Background IP, and (b) Precision shall solely own (or retain ownership of) all rights, title and interests in and to the Precision Background IP. If any Third Party becomes an Acquirer of Precision after the Effective Date pursuant to a Change of Control, any Patent rights and Know-How Controlled by the Acquirer before the relevant Change of Control transaction or thereafter during the Term will not be considered part of the Precision Background IP; provided, however, that any Patent rights or Know-How that would otherwise constitute Precision Background IP and are discovered or created by or on behalf of the Acquirer after the relevant Change of Control transaction by using any Precision Technology relating to the Research Program will be considered part of the Precision Background IP.

11.1.2Inventions. Ownership of Inventions arising in the course of the Research Program or otherwise under this Agreement shall be as follows:

(a)Lilly shall solely own (or retain ownership of) all Inventions discovered, created, acquired, conceived or reduced to practice, solely by or on behalf of Lilly or any of its Affiliates in the course of the Research Program or otherwise in the course of performing activities under this Agreement, except to the extent constituting Precision Sole IP (“Lilly Sole IP”);

(b)Precision shall solely own (or retain ownership of) (i) all Inventions discovered, created, acquired, conceived or reduced to practice, solely by or on behalf of Precision or any of its Affiliates in the course of the Research Program or otherwise in the course of performing activities under this Agreement, and (ii) [***] (“Precision Sole IP”). Lilly agrees to assign and hereby assigns to Precision all of its and its Affiliates’ right, title and interests in and to the Precision Sole IP and agrees to execute such documents and perform such other acts as Precision may reasonably request to obtain, perfect and enforce the Precision Sole IP and the assignment thereof; and

(c)Except to the extent constituting Precision Sole IP, any Invention discovered, created, conceived, reduced to practice or acquired, jointly by or on behalf of the Parties in the course of the Research Program or otherwise in the course of performing activities under this Agreement (“Joint IP”), will be jointly owned by the Parties.

11.1.3Inventorship. Inventorship as between the Parties will be determined in accordance with U.S patent laws. All such determinations shall be documented to ensure that the Patent claims in any divisional or continuation patent applications reflect appropriate inventorship.

11.1.4Rights of Joint Owners. Subject to the licenses and obligations of exclusivity granted hereunder and the payment obligations under Article 9, each Party shall have full rights to exploit and license Joint IP (and any Patent rights therein), without any obligation or requirement of an accounting to the other Party.

11.1.5Independent Development. Subject to the licenses and obligations of exclusivity granted hereunder, nothing in this Agreement shall be construed as limiting either Lilly’s or Precision’s right to research, develop, improve and in-license technology related to the Lilly Background IP (in the case of Lilly) or Precision Background IP (in the case of Precision) outside the scope of this Agreement in its ordinary course of business.

(a)Enabling Technology for the Licensed Products will be secured: (i) [***] to the extent necessary for Precision (as determined by Precision) to use the ARCUS Technology or to design, create, select or optimize ARCUS Nucleases [***] (“Platform-Enabling IP”); or (ii) [***] to the extent it relates to other elements of the Licensed Products, [***].

(b)If Precision or any of its Affiliates [***] discovers, creates, conceives or reduces to practice or acquires, and Controls, any Patent rights or Know-How outside the course of performing activities under this Agreement after the Effective Date that is necessary or reasonably useful for the Research, Development, making, having made, use, keeping, importation, exportation, offering for sale, sale, Commercialization, or other exploitation of a Licensed Product, including any such Patent that Covers a Licensed Product (“After-Acquired IP”), [***].

11.1.7Contribution of Licensed Precision Technology. Precision shall inform Lilly in writing, prior to contributing to any Research or Pre-Clinical Development to be conducted under any Research Plan any portion of the Precision Technology that is in-licensed from a Third Party, the contribution of which would prevent or conflict with the ownership and use rights with respect to Patents and Know-How contemplated by this Agreement. Lilly acknowledges that it has received a copy of the Cellectis Agreement and the Duke Agreement prior to the Execution Date.

11.1.8Assignment Obligation. Each Party shall cause all of its Affiliates, employees, agents, independent contractors, consultants, and others who perform activities for such Party under this Agreement to be under an obligation to assign (or, if such Party is unable to cause such person or entity to agree to such assignment obligation despite such Party using reasonable efforts to negotiate such assignment obligation, provide a license, preferably exclusive, under) to such Party their rights in and to any Inventions and all intellectual property rights therein, except where Applicable Law requires otherwise and except in the case of governmental, not-for-profit and public institutions that have standard policies against such an assignment (in which case a Party shall obtain a suitable license, preferably exclusive, or right to obtain such a license). Each Party shall use reasonable efforts to promptly disclose to the other Party in writing all

Inventions, including any invention disclosures, or other similar documents, submitted to it by its employees, agents or independent contractors describing such Inventions, and all information relating to such Inventions to the extent necessary or useful for the preparation, filing and maintenance of any Patent with respect to such Invention.

11.2.1Patent Working Group Representatives. Each Party shall designate to the other Party in writing a patent Prosecution and Maintenance representative to liaise with the other Party’s Prosecution and Maintenance representative via the Patent Working Group with respect to the Prosecution and Maintenance of Patents under this Section 11.2. Each Party may update its patent Prosecution and Maintenance representative at any time upon written notice to the other Party.

(a)Lilly has the sole right, but not the obligation, to Prosecute and Maintain any Patents constituting or claiming any Lilly Background IP or Lilly Sole IP, at Lilly’s sole cost and expense;

(b)Subject to Section 11.2.2(c) with respect to any Licensed Product Patents, Precision has the sole right, but not the obligation, to Prosecute and Maintain any Patents constituting or claiming any Precision Background IP or Precision Sole IP, at Precision’s sole cost and expense, and will give Lilly (by means of the Patent Working Group) the opportunity to review (i) the text of any application covering or claiming Precision Product IP (whether included in Precision Background IP or Precision Sole IP) and (ii) responses to office actions related thereto, in each case, before filing of the relevant application or responding to such office action. Precision will reasonably consider any input or feedback from Lilly with respect to the foregoing, provided, that Precision shall have the final authority with respect to any such decisions;

(c)In addition to the rights of Lilly set forth in Section 11.2.2(b), with respect to each Licensed Product Patent, (A) Precision shall not [***], (B) subject to Applicable Laws, Lilly shall [***], and (C) if [***], Lilly shall [***].

(a)If Lilly determines that an application for a Patent filed, or sought to be filed, by Precision claims both [***], the Parties agree that, to the extent practicable, such application shall be divided into two (2) or more Patent applications, so that each application shall contain claims that cover only [***].

(b)If Precision determines that an application for a Patent filed, or sought to be filed, by Lilly claims both [***], the Parties agree that, to the extent practicable, such application shall be divided into two (2) or more Patent applications, so that each application shall contain claims that cover only [***].

(c)If the division contemplated in Sections 11.2.4(a) or (b) is not practicable, or a single claim covers both [***], such Patent application shall be subject to the provisions of this Agreement relating to [***]; provided, however, that if a Patent application containing claims covering [***] cannot be so divided, then such Patent application shall be subject to the provisions of this Agreement relating to [***].

(d)Similarly, an attempt shall be made to divide Patent applications into those that claim Inventions [***].

11.2.5Cooperation of the Parties. Each Party shall cooperate fully with the other Party in the Prosecution and Maintenance of Patents under this Section 11.2 at [***] cost (except as expressly set forth otherwise in this Article 11), including by: (a) executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, to enable the other Party to apply for and to Prosecute and Maintain such Patents in any country as permitted by this Section 11.2; and (b) promptly informing the other Party of any matters coming to such Party’s attention that may affect the Prosecution and Maintenance of any such Patents. Each Party will use reasonable efforts via good faith consultation through the Patent Working Group to avoid creating potential issues in Prosecution and Maintenance of Patents under this Section 11.2.

11.3.1Notice. Each Party shall notify the other within [***] of becoming aware of any alleged or threatened infringement by a Third Party of any of the Precision Patents, Lilly Patents, or Joint Patents, in each case in the Field in the Territory, and any related declaratory judgment, opposition, or similar action alleging the invalidity, unenforceability or non-infringement of any of the Precision Patents, Lilly Patents, or Joint Patents (collectively “Infringement”).

(a)As between the Parties, Lilly has the first right, but not the obligation, to bring and control any legal action, at [***] cost and expense, in connection with (i) any Infringement of any [***] or (ii) any Infringement of any Joint IP (other than any [***]) that is competitive with a Licensed Product. Lilly shall keep Precision reasonably informed of the status of such enforcement efforts for such Joint IP or [***], and shall consider in good faith Precision’s comments thereon. Lilly shall provide Precision with drafts of all material papers and statements to be filed with the court in sufficient time to allow Precision to review, consider and substantively comment thereon, and shall in good faith consider all reasonable comments thereto by Precision before filing such papers or statements. Precision may, at [***] expense, join as a party to such claim, suit, or proceeding and be represented in any such action by counsel of its own choice. If Lilly does not bring such legal action within [***] after the notice provided pursuant to Section 11.3.1 (or within such shorter period prior to the next deadline for any action that must be taken in order to bring such legal action), Precision may bring and control any legal action in connection with such Infringement, at [***] cost and expense as it reasonably determines appropriate so long as Lilly does not reasonably object to such action.

(b)As between the parties, Precision shall have the first right, but not the obligation, to bring and control any legal action, at [***] cost and expense, in connection with any Infringement of any Joint IP (other than any Infringement described in Section 11.3.2(a)). Precision shall keep Lilly reasonably informed of the status of such enforcement efforts for such Joint IP, and shall consider in good faith Lilly’s comments thereon. Precision shall provide Lilly with drafts of all material papers and statements to be filed with the court in sufficient time to allow Lilly to review, consider and substantively comment thereon, and shall in good faith consider all reasonable comments thereto by Lilly before filing such papers or statements.

Lilly acknowledges and agrees that (a) Precision has no rights or responsibility for enforcing the Cellectis Patents, and therefore all references

to Precision Background IP in this Section 11.3 shall be deemed to exclude the Cellectis Patents for all purposes, (b) prior to initiating enforcement actions against a Third Party with respect to certain Precision Patents which are subject to the non-exclusive license granted by Precision to Cellectis S.A. pursuant to the Cellectis Agreement, Precision is required by the Cellectis Agreement to confirm that Cellectis S.A. has not granted a license to such Third Party under such Precision Patents, and Lilly will cooperate with Precision in taking such actions as required by the Cellectis Agreement, and (c) Duke retains discretion as to whether to become a party plaintiff and has certain rights with respect to enforcement of Patents contained within the Duke IP in the event Precision does not enforce such Patents.

11.3.4Lilly Background IP and Lilly Sole IP. Lilly has the sole right to initiate any proceedings or take other appropriate actions against an Infringement of any Lilly Background IP or Lilly Sole IP or to defend against any challenge of a Lilly Background IP or Lilly Sole IP.

11.3.5Allocation of Recoveries. Any recoveries resulting from enforcement action relating to a claim of Infringement shall be [***].

11.3.6Cooperation. At the request and expense of the Party bringing an action under this Section 11.3, the other Party shall provide reasonable assistance in connection therewith, including by executing reasonably appropriate documents, cooperating in discovery and joining as a party to the action if required by Applicable Law to pursue such action. In connection with any such enforcement action, the Party bringing the action shall not enter into any settlement admitting the invalidity or non-infringement of, or otherwise impairing the other Party’s rights in the applicable Patents without the prior written consent of the other Party.

11.4Defense and Settlement of Third Party Claims. Each Party shall promptly notify the other in writing of: (a) any allegation by a Third Party that the activity of either of the Parties pursuant to this Agreement infringes or may infringe the intellectual property rights of such Third Party; or (b) any declaratory judgment action that is brought naming either Party as a defendant and alleging invalidity of any of the Lilly Patents, Precision Patents, or Joint Patents. Precision has the sole right to control any defense of any such claim described in (a) involving alleged infringement of Third Party rights by Precision’s activities at [***] expense and by counsel of its own choice, and Lilly may, at [***] expense, be represented in any such action by counsel of its own choice. Lilly has the sole right to control any defense of any such claim described in (a) involving alleged infringement of Third Party rights by Lilly’s activities at [***] expense and by counsel of its own choice, and Precision may, at [***] expense, be represented in any such action by counsel of its own choice. Neither Party may settle any patent infringement litigation under this Section 11.4 in a manner that admits the invalidity or unenforceability of the other Party’s Patents or a Joint Patent or imposes on the other Party restrictions or obligations or other liabilities, without the written consent of such other Party, which consent shall not be unreasonably withheld, conditioned, or delayed. Nothing in this Section 11.4 will limit any indemnification rights or obligations of a Party under Article 13.

11.5Patent Extension. The Parties shall cooperate through the Patent Working Group in determining which Patent claiming or covering a Licensed Product should be extended, and thereafter the Parties shall cooperate in obtaining patent term restorations, supplemental protection certificates or their equivalents, and other forms of patent term extensions for a given Licensed Product with respect to any applicable Precision Patent, Lilly Patent, or Joint Patent in any country or region where applicable. Lilly shall have final decision-making authority with respect to decisions regarding patent term extensions with respect to Lilly Patents and [***]. Subject to Lilly’s rights with respect to Lilly Patents and [***], Precision shall have final decision-making authority with respect to decisions regarding patent term extensions with respect to Precision Patents and [***].

11.6CREATE Act. It is the Parties’ intention that this Agreement is a “joint research agreement” as that phrase is defined in 35 U.S.C. § 102(c) as amended by the Cooperative Research and Technology Enhancement (CREATE) Act, including the provisions of 35 U.S.C. § 102(b)(2)(c). The Parties agree to cooperate and to take reasonable actions to maximize the protections available for the Licensed ARCUS Nucleases and Licensed Products under such safe harbor provisions.

11.7Trademarks. Lilly shall have the right to select, and will be free, in its sole discretion, to use and to register in any trademark office in the Territory, any trademark for use with a Licensed Product (the “Licensed Product Trademarks”); provided that Lilly shall not use, file applications for, or register any trademarks owned by Precision (or its Affiliates), whether stand-alone or in combination with a design element, for the benefit of branding (including co-branding) without the prior written consent of Precision. As between the Parties, Lilly shall own all right, title and interest in and to any such Licensed Product Trademarks adopted by Lilly for use with Licensed Product, and is responsible for the registration, filing, maintenance and enforcement thereof.

NOTHING IN THIS AGREEMENT SHALL BE CONSTRUED AS A REPRESENTATION MADE OR WARRANTY GIVEN BY EITHER PARTY THAT EITHER PARTY WILL BE SUCCESSFUL IN OBTAINING ANY PATENTS OR THAT ANY PATENTS WILL ISSUE BASED ON A PENDING APPLICATION. WITHOUT LIMITING THE RESPECTIVE RIGHTS AND OBLIGATIONS OF THE PARTIES EXPRESSLY SET FORTH HEREIN, EACH PARTY SPECIFICALLY DISCLAIMS ANY GUARANTEE THAT ANY PROGRAM OR LICENSED PRODUCTS WILL BE SUCCESSFUL, IN WHOLE OR IN PART.

13.1.1By Precision. Subject to Section 13.1.3, Precision shall defend, indemnify and hold harmless Lilly and its Affiliates, and their respective directors, officers, employees, and agents (each, a “Lilly Indemnitee”) from and against any and all costs, fees, expenses, losses, liabilities, and damages, including reasonable legal expenses and attorneys’ fees (collectively, “Losses”) to which any Lilly Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party (a “Claim”) to the extent such Losses arise out of: (a) the gross negligence or willful

misconduct of Precision or its Affiliates in connection with its activities under this Agreement; (b) the breach of this Agreement or the representations, warranties, and covenants made hereunder by Precision; (c) [***]; (d) [***]; or (e) [***]; except, in each case, to the extent such Losses result from matters subject to clause (a), (b), or (c) of Section 13.1.2.

13.1.2By Lilly. Subject to Section 13.1.3, Lilly shall defend, indemnify and hold harmless Precision, its Affiliates, Duke, and its and their respective directors, officers, employees and agents (each, a “Precision Indemnitee”) from and against any and all Losses to which any Precision Indemnitee may become subject as a result of any Claim to the extent such Losses arise out of: (a) the gross negligence or willful misconduct of Lilly, its Affiliates, or their respective Sublicensees in connection with its activities under this Agreement; (b) the breach of this Agreement or the representations, warranties and covenants made hereunder by Lilly; or (c) [***]; except, in each case, to the extent such Losses result from matters subject to clause (a), (b), (c) (d) or (e) of Section 13.1.1.

13.1.3Procedure. A Party that intends to claim indemnification under this Article 13 (the “Indemnitee”) shall promptly notify the Indemnitor (the “Indemnitor”) in writing of any Claim in respect of which the Indemnitee intends to claim such indemnification. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any action with respect to a Claim shall only relieve the Indemnitor of its indemnification obligations under this Article 13 if and to the extent the Indemnitor is actually and materially prejudiced thereby. The Indemnitor has sole control of the defense or settlement thereof. The Indemnitee shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Claim covered by this indemnification. The Indemnitee may participate at its expense in the Indemnitor’s defense of and settlement negotiations for any Claim with counsel of the Indemnitee’s own selection. The Indemnitor shall not settle any Claim without the prior written consent of the Indemnitee, not to be unreasonably withheld, conditioned or delayed.

15.2.2Dispute. If the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in a notice provided by the other Party in accordance with Section 15.2.1, and such alleged breaching Party provides the other Party notice of such dispute within the applicable cure period, then the non-breaching Party may not terminate this Agreement under Section 15.2.1 unless and until it has been finally determined pursuant to Article 16 that the alleged breaching Party has materially breached this Agreement and such Party fails to cure such breach within [***] following such court's decision.

15.4.2if Precision, its Affiliates, or sublicensees, directly or indirectly, (a) initiate, request or participate in an interference or opposition proceeding with respect to any Lilly Patents, (b) make, file, maintain or participate in any claim, demand, lawsuit, cause of action or any other administrative, judicial or similar proceeding to challenge the validity, enforceability or patentability of any Lilly Patents, or (c) oppose any extension of, or the grant of a supplementary protection certificate with respect to, any Lilly Patents (in each case, (a), (b) or (c)), other than in response to a threat of an infringement claim by Lilly, then Lilly may terminate, upon [***] prior written notice to Precision, this Agreement [***]; provided, however, that if Precision or its applicable Affiliate or the applicable sublicensee withdraws (or causes to be withdrawn) the applicable action described in above in this Section 15.4.2 within [***] after being requested to do so by

15.5Effects of Termination. Upon any termination of this Agreement, the following will apply, provided that if this Agreement is terminated only with respect to specified Licensed Products (“Terminated Products”) and not in its entirety, then the following will apply to such Terminated Products only, and if this Agreement is terminated in its entirety, then all Licensed Products will be deemed Terminated Products. If this Agreement is terminated with respect to a Collaboration Target, or a Collaboration Target otherwise ceases to be a Collaboration Target pursuant to the terms of this Agreement, all Licensed Products Directed Against such Collaboration Target will be deemed Terminated Products.

15.5.1Termination of Licenses. All licenses for Terminated Products granted under Article 7 terminate automatically as of the termination effective date and all such rights shall revert to Precision; provided that, if Lilly (or its Affiliates or Sublicensees) has inventory of usable Licensed Product(s) as of the effective date of termination, then Lilly (and its Affiliates and Sublicensees) may continue to sell off such inventory of Licensed Products in the Field in the Territory (and fulfill customer orders therefor) until the earlier to occur of [***] after the effective date of termination and the date on which Lilly (or its Affiliates or Sublicensees) no longer has such inventory of Licensed Product(s) and shall pay Precision any applicable royalties due based on such sales. Any permitted sublicense granted by Lilly or its Affiliate to a Third Party under the licenses granted to Lilly under this Agreement shall survive the termination of this Agreement and Lilly shall endeavor in good faith to assign such sublicense to Precision such that such sublicense becomes a direct license between Precision and the Sublicensee on the same terms and conditions as those set forth in this Agreement to the extent applicable to the rights granted by Lilly to such Sublicensee, provided that, such sublicense was granted in accordance with the terms of Section 7.3 and in the case where termination of this Agreement was for Lilly’s uncured material breach pursuant to Section 15.2, such Sublicensee did not cause such uncured material breach and such Sublicensee is, at the time of such termination, otherwise in compliance with the sublicense granted by Lilly to such Sublicensee and the applicable terms and conditions of this Agreement[***].

Confidential Proprietary Information, which may be retained by the legal department of the Receiving Party to confirm compliance with the non‑use and non‑disclosure provisions of this Agreement), and any Confidential Proprietary Information of the Disclosing Party contained in its laboratory notebooks or databases, provided that each Receiving Party may retain and continue to use such Confidential Proprietary Information of the Disclosing Party only to the extent necessary to exercise any surviving rights, licenses or obligations under this Agreement.

(v)grant to Precision a non-exclusive, worldwide, royalty-free, fully paid up license for use of the Licensed Product Trademarks that have been used in commerce solely with such Terminated Product (excluding any corporate name or logo of Lilly or any of its Affiliates and any trademarks that are used by Lilly or any of its Affiliates on products that are not Terminated Products), together with all goodwill relevant thereto, throughout the Territory;

(vi)Lilly shall not withdraw or cancel any such Terminated Product’s Regulatory Approval or Marketing Authorization or application for either, unless expressly instructed so by Precision in writing; provided that Precision shall be responsible for all costs and expenses for the maintenance of all Regulatory Approvals and Marketing Authorizations following receipt of notice of termination; and

(vii)following written request by Precision, Lilly shall take such other actions and execute such other instruments, assignments and documents that are reasonably necessary to effect the transfers and grants of rights under this Section 15.5.3(c) to Precision.

15.8Bankruptcy Code .

Either Party may, at any time and without waiving any remedy under this Agreement, seek from any court having jurisdiction any temporary injunctive or provisional relief necessary to protect the rights or property of that Party. Any final judgment resolving a Dispute may be enforced by either Party in any court having appropriate jurisdiction.

17.5Severability. If, for any reason, any part of this Agreement is adjudicated invalid, unenforceable, or illegal by a court of competent jurisdiction, (a) such adjudication shall not, to the extent feasible, affect or impair, in whole or in part, the validity, enforceability, or legality of any remaining portions of this Agreement, (b) this Agreement shall be construed and enforced as if such invalid, unenforceable or illegal provision had never comprised a part hereof, (c) all remaining portions will remain in full force and effect and shall not be affected by the invalid, unenforceable or illegal provision or by its severance herefrom, and (d) in lieu of such invalid, unenforceable or illegal provision, the Parties shall use reasonable efforts to seek and agree on an alternative valid and enforceable provision that preserves the original purpose and intent of this Agreement.

17.6Non-Use of Names. Precision shall not use the name, trademark, logo, or physical likeness of Lilly or its respective officers, directors or employees, or any adaptation of any of them, in any advertising, promotional or sales literature, without Lilly’s prior written consent; provided that Precision shall have the right to use the name and logo of Lilly on its website solely for the purpose of referring to Lilly as a partner of Precision. Precision shall require its Affiliates to comply with the foregoing. Lilly shall not use the name, trademark, logo, or physical likeness of Precision or its officers, directors or employees, or any adaptation of any of them, in any advertising, promotional or sales literature, without Precision’s prior written consent. Lilly shall require its Affiliates and Sublicensees to comply with the foregoing.

17.7Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other, except that a Party may make such an assignment or transfer, without the other Party’s consent to: (a) its Affiliate, provided that such Party shall remain primarily liable for any acts or omissions of such Affiliate; or (b) to an Acquirer in connection with a Change of Control, subject to Section 17.8. Any permitted assignee shall, in writing to the non-assigning party, expressly assume performance of such assigning Party’s rights and obligations. Any permitted assignment or transfer is binding on the successors of the assigning or transferring Party. Any assignment or transfer or attempted assignment or transfer by either Party in violation of the terms of this Section 17.7 is null, void and of no legal effect.

17.8.1Notification of Change of Control. Precision shall provide Lilly with written notice of any Change of Control of Precision promptly, but no later than [***], following the earlier of the first public announcement of such Change of Control or the execution of a definitive agreement relating to such Change of Control (or, if not prohibited under Applicable Law or by the terms of any written agreement between Precision and any third party, any earlier date prior to the first public announcement of, or execution of a definitive agreement pertaining to such Change of Control, as determined in Precision’s sole discretion), which notice shall describe in reasonable detail the nature of the transaction and the identity of the Acquirer (a “Change of Control Notice”). If Precision undergoes a Change of Control, then Section 17.8.3 shall apply. For avoidance of doubt, a Change of Control of Precision shall not in any way limit or alter Lilly’s termination rights in accordance with Section 15.3, and the provisions of Section 17.8.3 below shall only apply if Lilly has not exercised any such termination right.

17.8.2Notification of Sale Process. If, during the Target Nomination Period, Precision, following authorization from its board of directors, determines to solicit from two or more Third Parties indications of interest or proposals providing for a Change of Control of Precision (the “Solicitation”), then Precision shall notify Lilly of such determination promptly following the first Solicitation. In connection therewith, Precision shall provide Lilly with an opportunity to participate in the process undertaken by Precision to make such Solicitations (a “Process”) by [***]. Lilly’s opportunity to participate in such Process shall be contingent upon [***]. The obligations set forth in this Section 17.8.2 shall in no way restrict Precision’s right to (i) determine whether to make any Solicitations, (ii) the type of terms of any Process it may choose to undertake if it

were to decide to make Solicitations or (iii) the counterparties (if any) with which it enters into any definitive agreement in connection with any Solicitation or Change of Control, other than to provide Lilly with the opportunity to participate as set forth in this Section 17.8.2. For the avoidance of doubt, nothing set forth in this Agreement (including this Section 17.8.2) shall obligate Precision to provide Lilly with any other rights with respect to any Process (including any rights to remain in any Process or consummate a Change of Control) or any right of first offer or right of first negotiation with respect to any Change of Control.

17.8.3Effects of Change of Control. Except in the scenario set forth in Section 17.8.5 below (in which case, the terms of Section 17.8.5 shall apply to such scenario), following a Change of Control of Precision, Lilly may [***].

17.8.4Acquirer Engaged in Competing Program. If Precision undergoes a Change of Control and, as of the closing date of such Change of Control transaction, the applicable Acquirer is engaged in a Competing Program, then Lilly may, by written notice delivered to Precision within [***] following the earlier of the first public announcement of such Change of Control or Lilly’s receipt of a Change of Control Notice from Precision, [***]; provided, that [***].

17.8.5Acquirer Not Engaged in Competing Program. If Precision undergoes a Change of Control and, as of the closing date of such Change of Control transaction, the applicable Acquirer is not engaged in a Competing Program, then the following shall apply:

(a)[***], then Lilly may, by written notice delivered to Precision within [***] following the earlier of the first public announcement of such Change of Control or Lilly's receipt of a Change of Control Notice from Precision[***]; and

(b)[***], then the Research Program and this Agreement shall continue in the same manner as prior to the Change of Control [***].

17.8.7[***]. Promptly following the first to occur of any of the following events in relation to an Acquirer of Precision: (a) the effective date of a Change of Control of Precision [***], (b) Lilly’s delivery to Precision of a Nomination Request pursuant to Section 3.2.1 or a Replacement Request pursuant to Section 3.3.1 (if applicable) specifying the identity of a Target that Lilly desires to include as a Collaboration Target under this Agreement, [***], or (c) the initiation of [***] (each of (a), (b) and (c), with respect to such Competing Program, the “Firewall Event”), Precision shall implement and enforce Firewalls between the applicable Research Program and Competing Program for the duration of the applicable Firewall Period.

17.8.8Firewall Audits. Lilly shall have the right, through a designated Third Party auditor reasonably acceptable to Precision, to audit Precision’s (and, as applicable, its Affiliates’) implementation and enforcement of Firewalls under this Section 17.8 for purposes of confirming compliance with the Firewalls, identifying any vulnerabilities or breaches and requiring Precision (or its Affiliates) to promptly remediate any non-compliance identified by such audit. In connection with such audit, duly authorized representatives of Lilly’s designated auditor may make an on-site visit to Precision (or its Affiliate) for the purpose of conducting such audit. Precision may require such auditor to execute a reasonable confidentiality agreement prior to commencing the audit, provided that the results of such audit (excluding all Third Party confidential information and any of Precision’s or its Affiliates’ confidential information that Lilly does not otherwise have the right to access under this Agreement) may be shared with Lilly. Lilly may conduct such audits from time to time as reasonably necessary to confirm Precision’s compliance with such Firewall requirements [***]. Any audits described under this Section 17.8.8 shall be conducted during Precision’s regular business hours, for a duration only as reasonably necessary to confirm Precision’s compliance with the applicable Firewall requirements, and shall not unreasonably interfere with or impede Precision’s business operations. Lilly shall provide Precision with written notice of such audit at least [***] prior to such requested audit (or such shorter period as may be designated by Lilly if Lilly reasonably believes at any time that Precision is not in compliance with such Firewall requirements). All such audits shall be conducted at Lilly’s cost and expense. If the auditor identifies any breach of the Firewall, Lilly and/or the auditor will notify Precision, and Precision will promptly (and will use reasonable efforts to ensure its Affiliates promptly) take all action necessary to remedy such breach, and will provide Lilly with reasonable assurance that such action has been taken, at Precision’s sole expense.

17.9Waivers. The failure of a Party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a Party of a particular provision or right shall be

in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such Party.

17.10Force Majeure. Neither Party shall be responsible to the other for any failure or delay in performing any of its obligations under this Agreement or for other nonperformance hereunder (excluding, in each case, the obligation to make payments when due) if such delay or nonperformance is caused by strike, fire, flood, earthquake, accident, war, act of terrorism, epidemics, pandemics, the spread of infectious diseases, quarantines, act of God or of the government of any country or of any local government, or by any other cause unavoidable or beyond the control of any Party hereto. In such event, such affected Party shall use Commercially Reasonable Efforts to resume performance of its obligations and will keep the other Party informed of actions related thereto.
