8.3.4 Notice of Missing Payment. If Metagenomi believes any of the foregoing milestone event (Development, Regulatory Approval or Commercial sale) has occurred and it has not received payment of same from Affini-T, it shall so notify Affini-T in writing and shall provide to Affini-T documentation or other information that supports its belief.

8.4 Payment of Royalties; Royalty Rates; Accounting and Records.

8.4.1 Payment of Royalties. On a Licensed Product-by-Licensed Product and country-by-country basis, during the applicable Royalty Term for such Licensed Product and country, Affini-T shall pay Metagenomi tiered royalties on the worldwide Annual Net Sales of such Licensed Product at the royalty rates set forth below. No more than one royalty payment shall be due per Licensed Product per Calendar Quarter during the Royalty Term for such Licensed Product.

Annual Net Sales Thresholds (Determined on an Affini-T Clinical Target-by- Affini-T Clinical Target basis)	Exclusively Licensed Product Royalty Rate			Non-Exclusively Licensed Product Royalty Rate
Annual Net Sales of all Licensed Products directed to a given [***] is less than [***]		[	***]		[	***]
Annual Net Sales of all Licensed Products directed to a given [***]is equal to or greater than [***]but less than [***]		[	***]		[	***]
Annual Net Sales of all Licensed Products directed to a given [***]is equal to or greater than [***]but less than [***]		[	***]		[	***]
Annual Net Sales of all Licensed Products directed to a given [***]Target is equal to or greater than [***]		[	***]		[	***]

Once the Royalty Term with respect to a given Licensed Product and country has expired, the Net Sales of such Licensed Product in such country shall not count towards cumulative Net Sales for purposes of establishing Net Sales tiers pursuant to this Section 8.4.1.

8.4.2 Adjustments to Royalty Payments.

(a) Notwithstanding anything to the contrary in Section 8.4.1, if any Licensed Product is sold in a country and [***], then the royalties shall be [***], continuing until [***] with respect to such Licensed Product and such country at issue.

(b) If Affini-T, or any of its Affiliates or Sublicensees, is a party to a (sub)license from one or more Third Parties, including any Third Party license to Patent Rights which Cover, or Know-How which relates to a given Licensed Product (or its use or manufacture), because it is necessary or useful for Affini-T, its Affiliate or Sublicensee to avoid infringement of such Patent Right or misappropriation of such Know-How in the Development, Manufacture, Commercialize or other exploitation of a Licensed Product in a given country (each such Third Party license is referred to herein as a “Third Party License”), then, [***] of any payments owed by Affini-T or any of its Affiliates or Sublicensees to any such Third Party for such a Third Party License (collectively, the “Third Party Payments”) shall be creditable against royalties payable to Metagenomi under Section 8.4.1; provided, that in no event will such credit reduce the royalties payable to Metagenomi for a given Calendar Quarter by [***]; provided, further, that if additional reductions would be possible but for the foregoing [***], then such amounts may be rolled forward to reduce future royalty payments. Notwithstanding the foregoing, if the Third Party License is necessary or useful for Affini-T, its Affiliate or Sublicensee to avoid infringement of one or more Patent Rights or misappropriation of Know-How as a result of exploitation of Metagenomi IP or the Metagenomi Reagents in accordance with the terms of this Agreement, then [***] of any Third Party Payments in connection with such Third Party License shall be creditable against payments to Metagenomi under Sections 8.3 and 8.4.1.

(c) If Affini-T is required to grant a Compulsory License to a Third Party with respect to a Licensed Product, as applicable in any country, and such Third Party actually sells such Licensed Product in such country under such Compulsory License, with a royalty rate lower than the applicable royalty rate provided by this Section 8.4, then the Parties shall share all amounts actually received by Affini-T or its Affiliates or Sublicensees from any Compulsory License in consideration of the sale of a Licensed Product less any withholding tax or other taxes as may be required under Applicable Law and actually withheld from such payment due to Affini-T, its Affiliate or Sublicensee, as applicable, [***] with Affini-T’s share included in the royalty payments and reports made pursuant to Section 8.4.3.

8.4.3 Payment Dates and Reports. Affini-T shall provide a report showing the Net Sales of each Licensed Product and calculation of the amount of royalty due to Metagenomi within [***] after the end of each Calendar Quarter in which a sale of such Licensed Product occurs, commencing with the Calendar Quarter in which [***]. Metagenomi shall submit an invoice to Affini-T based on such royalty report pursuant to Section 8.4.5(c) and Affini-T shall pay such royalty payments within [***] after receipt of invoice.

8.4.4 Records; Audit Rights. Affini-T and its Affiliates and Sublicensees involved in booking sales of the Licensed Product shall keep and maintain for [***] from the end of the Calendar Year in which Net Sales occurred (the “Retention Period”) complete and accurate records of gross sales and Net Sales by, as applicable, Affini-T and its Affiliates and Sublicensees of each Licensed Product, in sufficient detail to allow royalties to be determined accurately. Metagenomi shall have the right during the applicable Retention Period to appoint at its expense a nationally recognized independent certified public accountant reasonably acceptable to Affini-T to audit the relevant records of Affini-T and its Affiliates and Sublicensees to verify that the amount of such payment was correctly determined. Affini-T and its Affiliates and Sublicensees shall each make its records available for audit by such nationally recognized independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon [***]written notice from Metagenomi. Such audit right shall not be exercised by Metagenomi more than once in any Calendar Year or more than once with respect to sales of a particular Licensed Product in a particular period and such audit shall not unreasonably

35

interfere with or impede Affini-T’s or its Affiliate’s or sublicensee’s business operations. All records made available for audit shall be deemed to be Confidential Information of Affini-T. The results of each audit, if any, shall be provided to and are binding on both Parties absent manifest error; provided, that, Affini-T shall be provided an opportunity to discuss the findings of any such audit with the auditor prior to disclosure of the results thereof to Metagenomi. In the event there was an underpayment by Affini-T hereunder, Affini-T shall promptly (but in any event no later than [***] after Affini-T’s receipt of the report so concluding) make payment to Metagenomi of any shortfall. Metagenomi shall bear the full cost of such audit unless such audit discloses an underreporting by Affini-T of [***] or at least [***] of the aggregate amount of royalties payable in any Calendar Year, in which case Affini-T shall reimburse Metagenomi for [***]. In the event there was an overpayment by Affini-T hereunder, Affini-T may, at its discretion, credit such overpayment in the next royalty payment or request Metagenomi to and Metagenomi shall promptly (but in any event no later than [***] after Metagenomi’s receipt of the report so concluding) make repayment to Affini-T of any such overage.

8.4.5 Payments; Withholding Tax.

(a) All payments made by Affini-T under this Article 8 shall be made by wire transfer from a banking institution in US Dollars in accordance with instructions given in writing from time to time by Metagenomi; provided however that Affini-T will, or its vendor on behalf of Affini-T, will disburse payments only to Metagenomi’s jurisdiction of incorporation or to a jurisdiction in which Metagenomi has a significant business presence.

(b) If Applicable Laws require withholding of income or other taxes imposed upon any payments made by Affini-T to Metagenomi under this Agreement, including any value added tax or sales tax, Affini-T shall (i) make such withholding payments as may be required, (ii) subtract such withholding payments from such payments, (iii) submit appropriate proof of payment of the withholding taxes to Metagenomi within a reasonable period of time, and (iv) promptly provide Metagenomi with all official receipts with respect thereto. Affini-T shall render Metagenomi reasonable assistance in order to allow Metagenomi to obtain the benefit of any present or future treaty against double taxation which may apply to such payments.

(c) All invoices required to be submitted to Affini-T under this Agreement shall be submitted by Metagenomi to Bill.com or such other vendor designated by Affini-T in writing from time to time.

9. TREATMENT OF CONFIDENTIAL INFORMATION; PUBLICITY.

9.1 Confidentiality.

9.1.1 Confidentiality Obligations. Metagenomi and Affini-T each recognizes that the other Party’s Confidential Information and Proprietary Materials constitute highly valuable assets of such other Party. Metagenomi and Affini-T each agrees that, during the Term and for an additional [***] after termination or expiration of this Agreement, (a) subject to Section 9.1.2, it will not disclose, and will cause its Affiliates not to disclose, any Confidential Information or Proprietary Materials of the other Party, (b) it will not use, and will cause its Affiliates not to use, any Confidential Information or Proprietary Materials of the other Party, except as expressly

36

permitted in this Agreement, (c) it shall not attempt to reverse engineer, deconstruct or in any way determine the structure or composition of any of the other Party’s Proprietary Materials, and (d) it will use the same efforts to protect the other Party’s Confidential Information as it does to protect its own similar Confidential Information (but, in any event, no less efforts than a reasonable Person in the industry would use to protect similar information).

9.1.2 Limited Disclosure. Each Disclosing Party agrees that disclosure of its Confidential Information or any transfer of its Proprietary Materials may be made by the Receiving Party to any employee, director or agent of, or consultant to, such Receiving Party or to other Third Parties to enable such other Party to exercise its rights (including Affini-T’s right to fully exploit any Commercial License granted to it) or to carry out its responsibilities under this Agreement; provided, that, any such disclosure or transfer shall only be made to Persons who are bound by written obligations of confidentiality and non-use at least as strict as those described in Article 9. In addition, each Disclosing Party agrees that the Receiving Party may disclose Confidential Information of the Disclosing Party (a) on a need-to-know basis to such Receiving Party’s professional, legal and financial advisors, (b) as reasonably necessary in connection with an actual or potential (i) permitted license or sublicense of such Receiving Party’s rights hereunder, (ii) financing of such Receiving Party in a public or private offering, or (iii) merger, acquisition, consolidation, share exchange or other similar transaction involving such Receiving Party and any Third Party, (c) to any Third Party that is or may be engaged by a Receiving Party to perform services in connection with the Research Plan (or perform services in connection with carrying out Development or Commercialization activities) as necessary to enable such Third Party to perform such services, (d) as reasonably necessary to file, prosecute or maintain Patent Rights, or to file, prosecute or defend litigation related to Patent Rights, in accordance with this Agreement, (e) as reasonably necessary for Regulatory Filings or interactions with Regulatory Authorities, in each case relating to the Licensed Products, or (f) as required by Applicable Laws (including securities laws or regulations and the applicable rules of any public stock exchange in the case of any initial public offering or subsequent public offering or in response to rules or guidance of the United States Internal Revenue Service or other taxing authority, or in other legal processes, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or other securities trading institution); provided, that, in each case of clauses (a) – (c) any such disclosure or transfer shall only be made to Persons who are bound by written obligations of confidentiality and non-use consistent with those described in Article 9 (or industry standards in the case of a disclosure pursuant to clause (b)(ii)).

9.1.3 Requirement to Cooperate to Enable Accurate Public Disclosure. To the extent either Party discloses to the other Party any Confidential Information which is a fact, result or event relating to the Metagenomi Research Activities or the Development, Manufacture or Commercialization of any Licensed Product that the Receiving Party in good faith reasonably believes is insufficient to allow the Receiving Party to fully understand the materiality of such Confidential Information for purposes of determining whether the Receiving Party is required to disclose, to any Governmental Authority or publicly, any such Confidential Information in order to comply with Applicable Laws (including securities laws or regulations and the applicable rules of any public stock exchange), the Disclosing Party agrees to discuss such Confidential Information with the Receiving Party and provide any additional information reasonably necessary to enable the Receiving Party to assess the materiality, and the accuracy and completeness, of such information for such public disclosure purposes as the case may be, which additional information shall be treated as the Disclosing Party’s additional Confidential Information and shall be treated in accordance with the terms hereof.

37

9.2 Publicity.

9.2.1 Press Releases. The Parties shall, upon such timing as the Parties jointly agree, issue a joint press release with respect to this Agreement, and each Party may make subsequent public disclosure of the contents of such press release without further approval of the other Party. Subject to the foregoing, except as otherwise permitted under this Article 9, neither Party shall issue a press or news release or make any similar public announcement related to the Research Plan or the terms and conditions of this Agreement without the prior written consent of the other Party. If a Party determines the need to make an announcement related to this Agreement (as distinct from a publication related to a Licensed Product, which is subject to Section 9.2.2) is required by Applicable Laws, it shall, to the extent reasonably practicable and permitted, give the other Party at least [***] advance notice of the text of the announcement so that the other Party will have an opportunity to comment upon the announcement.

The word “Content” in this Section 9.2.1 means any information relating to the activities contemplated by this Agreement and does not include any other business information of the Requesting Party or information pertaining to the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995 relating to “forward-looking statements.” The Reviewing Party may notify the Requesting Party of any reasonable objections or suggestions that the Reviewing Party may have regarding the Content in the proposed public disclosure provided for review, and the Requesting Party shall reasonably consider any such objections or suggestions that are provided in a timely manner. The Requesting Party shall use diligent and good faith efforts to adopt the reasonable requests of the Reviewing Party with respect to its Confidential Information.

9.2.2 Right to Publish/Present. Notwithstanding the foregoing or anything to the contrary in this Agreement, except as set forth in the last sentence of this Section 9.2.2, Affini-T shall have the sole right to publish or publicly present all results or any and all milestone events achieved with respect to the research (including arising from or relating to the Metagenomi Research Activities), Development, Manufacture or Commercialization of any Licensed Product; provided, that, to the extent such publication contains Metagenomi’s Confidential Information, Affini-T shall submit a draft of any proposed press release, manuscript, abstract or speech to Metagenomi at least [***] prior to any such submission for publication and at least [***] prior to any such oral presentation and Metagenomi shall have the right to notify Affini-T in writing within such [***]or [***], as applicable, period if it reasonably determines that such draft contains Confidential Information of Metagenomi, in which case Affini-T shall remove such Confidential Information from the proposed press release, manuscript, abstract or speech. Subject to the foregoing portion of this Section 9.2.2, Metagenomi shall have the right to publish or present without the prior written consent of Affini-T so long as no Confidential Information of Affini-T is included in any such publication or presentation (including no Product Information).

38

9.3 Permitted Publication. Notwithstanding Section 9.2, either Party may include in a public disclosure, without prior delivery to or approval by the other Party, any information which has previously been included in a public disclosure pursuant to Section 9.2. A Party relying on this Section 9.3 shall bear the burden of establishing that information has previously been included in a public disclosure that has been approved pursuant to Section 9.2 or published or publicly disclosed by the other Party.

9.4 Use of Proprietary Materials. From time to time during the Term, either Party (the “Transferring Party”) may supply the other Party (the “Recipient Party”) with Proprietary Materials of the Transferring Party for use in connection with this Agreement. Any Proprietary Materials being provided to Recipient Party shall be accompanied by a Materials Transfer Record substantially in the form of Schedule 9.4, which shall be signed by an official representative of both Parties.

EACH PARTY ACKNOWLEDGES THAT THE PROPRIETARY MATERIALS ARE BEING SUPPLIED WITH NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, OR THAT THE USE OF THE PROPRIETARY MATERIALS WILL NOT INFRINGE ANY PATENT OR PROPRIETARY RIGHTS OF ANY THIRD PARTY.

10. INTELLECTUAL PROPERTY RIGHTS

10.1 Metagenomi In-Licensed IP. If Metagenomi knows or should have knowledge of any Metagenomi In-Licensed IP that Metagenomi has a right to sublicense (“Sublicenseable Metagenomi In-Licensed IP”), or Affini-T becomes aware of any Metagenomi In-Licensed IP, then Metagenomi or Affini-T, as applicable, shall promptly notify the other Party in writing of any such Metagenomi In-Licensed IP (i.e., Sublicenseable Metagenomi In-Licensed IP in the case of Metagenomi, and Metagenomi In-Licensed IP in the case of Affini-T), including, in the case of Metagenomi providing a general description of the relevant Sublicenseable Metagenomi In-Licensed IP and any applicable financial terms (if Affini-T initiates this process, then Metagenomi shall promptly respond to Affini-T’s initial notice advising whether such Metagenomi In-Licensed IP is Sublicenseable Metagenomi In-Licensed IP and, if it is, with such information). Upon receipt of any such notice from Metagenomi (including a subsequent

39

notice if Metagenomi is to provide information following an initial notice from Affini-T), Affini-T shall have the right to request, and Metagenomi shall provide, a copy of the license agreement and any amendments thereto with respect to such Sublicenseable Metagenomi In-Licensed IP (the “Upstream Agreement”) and answer any reasonable questions with respect to such Upstream Agreement and Sublicenseable Metagenomi In-Licensed IP. Following such discussions, Affini-T shall have the right to include such Metagenomi In-Licensed IP as Metagenomi Background IP hereunder upon written notice to Metagenomi subject to Affini-T agreeing to be subject to any pass-through obligations or limitations applicable to Affini-T’s exercise of such rights, including responsibility for payment obligations to the extent solely attributable to the rights granted to Affini-T. To the extent Sublicenseable Metagenomi In-Licensed IP is included as Metagenomi Background IP, Metagenomi shall comply with all terms and conditions of, and shall maintain in full force and effect each relevant Upstream Agreement related to such Sublicenseable Metagenomi In-Licensed IP and shall not terminate or amend any such Upstream Agreement in a way that could have an adverse effect on Affini-T’s rights without Affini-T’s prior written consent, such consent not to be unreasonably withheld or delayed.

10.2 Ownership of Agreement IP.

10.2.1 General. As between the Parties, all right, title and interest in any Agreement Know-How and Agreement Patent Rights, shall be owned as follows:

(a) Metagenomi shall solely own all (i) Agreement Know-How that solely (1) relates to the identification, characterization, composition of matter, and manufacture of Metagenomi Reagents, or (2) constitutes an improvement to Metagenomi Background IP (collectively (1) and (2), “Metagenomi Agreement Know-How”), and (ii) Patent Rights that Cover Metagenomi Agreement Know-How (“Metagenomi Agreement Patent Rights”) (collectively (i) and (ii), “Metagenomi Agreement IP”); and

(b) Affini-T shall solely own all (i) Agreement Know-How that is not Metagenomi Agreement Know-How (“Affini-T Agreement Know-How”), including all Agreement Know-How that constitutes an improvement to Affini-T Background IP, and (ii) Patent Rights that Cover Affini-T Agreement Know-How (“Affini-T Agreement Patent Rights”) (collectively (i) and (ii), “Affini-T Agreement IP”).

10.2.2 Notice, Assignments, Assistance.

(a) Each Party shall (i) promptly notify the other Party of any Agreement Know-How made by or on behalf of itself and that is to be owned by the other Party, and (ii) hereby assigns, transfers and conveys to the other Party, or its designee, all of such Party’s worldwide right, title and interest in and to any and all Agreement IP that is to be owned by such other Party in accordance with Section 10.2.1, including any and all moral rights and intellectual property rights inherent therein and appurtenant thereto, including all Patent Rights, copyrights, trademarks, Know-How and trade secrets and the rights to apply for the same.

40

(b) Upon the request and at the reasonable expense of the other Party, each Party shall execute and deliver any and all instruments and documents and take such other acts as may be necessary or desirable to document the assignment and transfer described in Section 10.2.2(a) or to enable such other Party to secure its rights in the applicable Agreement IP, including providing any necessary powers of attorney for such purpose.

10.2.3 CREATE Act.

11.1 Patent Prosecution.

11.1.1 Metagenomi Patent Prosecution Rights. Subject to the last sentence of this Section 11.1.1, Metagenomi shall be solely responsible (but not obligated) for the Patent Prosecution of the Metagenomi Agreement Patent Rights. Affini-T shall cooperate with and reasonably assist Metagenomi in connection with Metagenomi’s Patent Prosecution of the Metagenomi Agreement Patent Rights (including review and providing comments for responses to office actions or official actions from worldwide patent offices), including by obtaining assignments to reflect chain of title consistent with the terms of this Agreement. All Patent Costs incurred by Metagenomi in connection with the Patent Prosecution of such Patent Rights shall be the sole responsibility of Metagenomi. If Metagenomi decides to cease prosecution of or to allow to lapse any Metagenomi Agreement Patent Right, it shall inform Affini-T of such decision promptly and, in any event, so as to provide Affini-T a reasonable amount of time to meet any applicable deadline to establish or preserve such Patent Rights. Affini-T shall have the right, but not the obligation, to assume sole responsibility for continuing the prosecution of such Patent Rights and paying any required Patent Costs to maintain such Patent Rights or defend such Patent Rights. If Affini-T notifies Metagenomi that it desires to assume responsibility for any such Metagenomi Agreement Patent Right, then Affini-T will have the right to undertake the Patent Prosecution with respect to such Patent Right in Metagenomi’s name and such Patent Right shall cease to be a Metagenomi Patent Right for purposes of determining the Royalty Term.

11.1.2 Metagenomi’s Patent Defense Rights. Metagenomi will notify Affini-T within [***] of becoming aware of any declaratory judgment, opposition, or similar action alleging the invalidity, unenforceability or non-infringement of any of the Metagenomi Agreement Patent Rights in the Territory. Metagenomi shall only be primarily responsible (but not obligated) for the Patent Defense of Metagenomi Agreement Patent Rights. At Metagenomi’s reasonable expense, Affini-T shall cooperate with and assist Metagenomi in all reasonable respects, in connection with Metagenomi’s Patent Defense activities. All Patent Costs incurred by Metagenomi in connection with the Patent Defense of such Patent Rights shall be the sole responsibility of Metagenomi. If Metagenomi decides to cease such Patent Defense with respect to any such Patent Right, it shall inform Affini-T of such decision promptly and, in any event, so as to provide Affini-T a reasonable

41

amount of time to meet any applicable deadline to defend or preserve such Patent Rights. Affini-T shall have the right, but not the obligation, to assume sole responsibility for continuing such Patent Defense (and thereafter the prosecution of such Patent Rights). If Affini-T notifies Metagenomi that it desires to assume responsibility for any such Patent Defense, then Affini-T will have the right to undertake the Patent Defense with respect to such Patent Right in Metagenomi’s name.

11.1.3 Affini-T Prosecution Rights. As between the Parties, Affini-T, at its sole expense, shall be solely responsible for the Patent Prosecution of all Affini-T Patent Rights. Metagenomi shall cooperate with and assist Affini-T in all reasonable respects in connection with Affini-T’s Patent Prosecution of such Patent Rights, including by obtaining assignments to reflect chain of title consistent with the terms of this Agreement.

11.1.4 Affini-T’s Patent Defense Rights. Affini-T will notify Metagenomi within [***] of becoming aware of any declaratory judgment, opposition, or similar action alleging the invalidity, unenforceability or non-infringement of any Affini-T Patent Rights in the Territory. Affini-T shall be responsible for the Patent Defense of such Affini-T Patent Rights. Metagenomi shall cooperate with and assist Affini-T, at Affini-T’s reasonable expense, in all reasonable respects in connection with Affini-T’s Patent Defense activities. All Patent Costs incurred by Affini-T in connection with the Patent Defense of such Affini-T Patent Rights shall be, as between the Parties, the sole responsibility of Affini-T.

11.1.5 Information and Cooperation. Metagenomi shall (a) promptly provide Affini-T with copies of all patent applications with respect to Metagenomi Agreement Patent Rights to be filed pursuant to Section 11.1.1 and other material submissions and correspondence with the applicable patent offices, at least [***] (unless the circumstances require otherwise) prior to undertaking any filing for review and comment by Affini-T and (b) provide Affini-T and its patent counsel with an opportunity to consult with Metagenomi and its patent counsel regarding the filing and contents of any such application, amendment, submission or response, during such review period and as may otherwise be agreed by the Parties. The advice and suggestions of Affini-T and its patent counsel shall be taken into consideration in good faith by Metagenomi and its patent counsel in connection with such filing; provided, that, if Affini-T fails to timely provide any comment before the proposed filing or response date, Metagenomi’s obligations under this Section 11.1.4 shall be deemed to have been fulfilled.

11.2 Third Party Infringement.

11.2.1 If (a) Metagenomi becomes aware of any suspected infringement of any Metagenomi Patent Rights or misappropriation of any Agreement Know-How, in each case with respect to the use by a Third Party of the Metagenomi Reagents to make Gene Edits directed to an Affini-T Clinical Target in the Exclusive Field (“Infringement”); or (b) Affini-T becomes aware of an Infringement, then that Party shall promptly notify the other Party of such Infringement of which it is aware (each, an “Infringement Notice”). The Parties shall promptly meet to discuss any Infringement and the strategy for patent enforcement with respect to that Infringement; provided, that, at the request of either Party, the Parties shall first execute a common interest agreement before any such meetings or exchange of detailed information.

42

11.2.2 Metagenomi shall have the first right, but not the obligation, to address any such Infringement in the Territory with respect to the Metagenomi Agreement IP, taking reasonable steps, which may include the institution of legal proceedings or other action, and to compromise or settle such Infringement (each, an “Infringement Response”); provided, that: (A) Metagenomi shall keep Affini-T reasonably informed about any such Infringement Response and Affini-T shall provide all reasonable cooperation to Metagenomi in connection with such Infringement Response; (B) Metagenomi shall not take any position with respect to, or compromise or settle, any such Infringement that relates to any Metagenomi Agreement IP in any way that is reasonably likely to adversely affect the scope, validity or enforceability of any Affini-T Agreement IP, the Commercial License or any Licensed Product, without the prior consent of Affini-T, which consent shall not be unreasonably withheld, conditioned or delayed; and (C) if Metagenomi does not intend to or does not take any action to prosecute or defend an Infringement of Metagenomi Agreement IP within [***] after the date of the Infringement Notice, or ceases to diligently pursue an Infringement Response with respect to such an Infringement of Metagenomi Patent Rights, it shall promptly inform Affini-T in such a manner that such Infringement Response will not be prejudiced and Affini-T shall have the right, but not the obligation, to assume sole responsibility to prosecute or defend an Infringement of such Patent Rights and paying all future costs associated with such Infringement Costs. All costs, including attorneys’ fees, relating to an Infringement Response from Metagenomi shall be borne solely by Metagenomi.

11.2.3 Each Party shall have the right to participate and be represented by counsel that it selects, in any Infringement Response instituted or continued under Section 11.2.2 by the other Party. If a Party with the right to initiate an Infringement Response under Section 11.2.2 to eliminate an Infringement lacks standing to do so and the other Party has standing to initiate such action, then the Party with the right to initiate an action under Section 11.2.2 may name the other Party as plaintiff in such action or may require the Party with standing to initiate such Infringement Response at the expense of the other Party.

11.2.4 In any Infringement Response instituted under this Section 11.2, the Parties shall cooperate with and reasonably assist each other in all reasonable respects. Upon the reasonable request of the Party instituting that Infringement Response, the other Party shall join such Infringement Response and shall be represented using counsel of its own choice, at the requesting Party’s expense.

11.2.5 Any settlements, damages or monetary awards (“Recovery”) recovered by either Party pursuant to any Infringement Response shall, after reimbursing the Parties for their reasonable out-of-pocket expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses), be [***]or[***]

11.3 Defense of Claims. If any action, suit or proceeding is brought against either Party or any Affiliate of either Party alleging the misappropriation or infringement of the Know-How or Patent Rights of a Third Party by reason of the research, Development, Manufacture or Commercialization of any Licensed Product or component thereof, including receipt of any notices of infringement under 35 U.S.C. § 271(e)(2), 42 U.S.C. § 262(1), or 42 U.S.C. § 262(1)(9)(C), such Party shall notify the other Party within [***] of the earlier of (a) receipt of service of process in such action, suit or proceeding,

43

or (b) the date such Party becomes aware that such action, suit or proceeding has been instituted.
