The maximum total amount payable under this Section 7.8.3 (RT Target Development Milestones) shall not exceed one hundred million Dollars ($100,000,000) per RT Target subject to this Agreement pursuant to Section 7.8.1 (Milestone Payments, General). For clarity, no Milestone Payment is payable for subsequent or repeated achievements of the same RT Target Development and Regulatory Milestone Event with respect to the same Licensed Product (including formulations), or any subsequent Licensed Products with respect to an RT Target for which an RT

91

Target Development and Regulatory Milestone Event has occurred (see, e.g., the following example set forth in the remainder of this Section 7.8.3 (RT Target Development Milestones)). By way of example and not limitation, assume that a Licensed Product achieves the first RT Target Development and Regulatory Milestone Event for the first (1st) RT Target, and immediately after the Initiation of the Phase II Clinical Trial for such Licensed Product, Moderna decides to discontinue the Development of such Licensed Product Directed Against that RT Target. In such case, Moderna would pay Metagenomi the Milestone Payment corresponding to the first RT Target Development and Regulatory Milestone Event set forth in the table above upon the attainment of such first RT Target Development and Regulatory Milestone Event by such Licensed Product. Then, assume that a different Licensed Product for the same RT Target achieves the first RT Target Development and Regulatory Milestone Event. In such case, no Milestone Payment is due upon the attainment of the first RT Target Development and Regulatory Milestone Event with respect to the second Licensed Product, and Moderna would pay Metagenomi the Milestone Payments corresponding to the second RT Target Development and Regulatory Milestone Event set forth in the table above upon the attainment of such second RT Target Development and Regulatory Milestone Event by such second Licensed Product. With respect to each RT Target Development and Regulatory Milestone Event that has two potential options of either (i) or (ii) in the table above, if the first achievement is for the RT Target Development and Regulatory Milestone Event under clause (ii), and if there is a subsequent achievement for the clause (i) version of the same RT Target Development and Regulatory Milestone Event, then upon the occurrence of such subsequent achievement the difference between the amount of clauses (i) and (ii) shall be payable. By way of example, if the first Pricing and Reimbursement Approval in the United Kingdom is obtained for a Licensed Product Directed Against a particular RT Target in an Orphan Indication (a clause (ii) occurrence), then [***] would be owing in accordance with the table above, and if subsequently Pricing and Reimbursement Approval in the United Kingdom is obtained for a Licensed Product Directed Against the same RT Target in a Non-Orphan Indication, then an additional [***] would be due [***].

Moderna shall provide prompt written notice to Metagenomi upon achievement of an RT Target Development and Regulatory Milestone Event. Metagenomi shall send an invoice for the applicable Milestone Payment within sixty (60) days after receiving the written notice from Moderna.

7.8.4 RT Target Sales Milestones. The Milestone Payments to be made by Moderna to Metagenomi pursuant to Section 7.8.1 (Milestone Payments, General) with respect to the first occurrence of all Licensed Products Directed Against a given RT Target collectively achieving the below RT Target Sales Milestone Events are as follows:

RT Target Sales Milestone Event |  | Milestone Payment |
First Calendar Year in which annual Net Sales of all Licensed Products Directed Against such RT Target in the Territory exceed [***] |  |  | [ | ***]
First Calendar Year in which annual Net Sales of all Licensed Products Directed Against such RT Target in the Territory exceed [***] |  |  | [ | ***]
First Calendar Year in which annual Net Sales of all Licensed Products Directed Against such RT Target in the Territory exceed [***] |  |  | [ | ***]
First two consecutive Calendar Years in each of which annual Net Sales of all Licensed Products Directed Against such RT Target in the Territory exceed one and [***] |  |  | [ | ***]

92

The maximum total amount payable under this Section 7.8.4 (RT Target Sales Milestones) shall not exceed two hundred million Dollars ($200,000,000) per RT Target subject to this Agreement pursuant to Section 7.8.1 (Milestone Payments, General). If more than one RT Target Sales Milestone Event is achieved in the same Calendar Year, Moderna shall pay Metagenomi all Milestone Payments for such RT Target Sales Milestone Events achieved in such Calendar Year in accordance with this Section 7.8.4 (RT Target Development Milestones).

Moderna shall provide prompt written notice to Metagenomi upon achievement of an RT Target Sales Milestone Event. Metagenomi shall send an invoice for the applicable Milestone Payment within sixty (60) days after receiving the written notice from Moderna.

7.8.5 DT Moderna Target Development Milestones. The Milestone Payments to be made by Moderna to Metagenomi pursuant to Section 7.8.1 (Milestone Payments, General) with respect to the first Product for each DT Moderna Target achieving a DT Moderna Target Development and Regulatory Milestone Event described below during the Term are as follows:

DT Moderna Target Development and Regulatory Milestone Events |  | Milestone Payment |

The maximum total amount payable under this Section 7.8.5 (DT Moderna Target Development Milestones) shall not exceed one hundred million Dollars ($100,000,000) per DT Moderna Target subject to this Agreement pursuant to Section 7.8.1 (Milestone Payments, General). For clarity, no Milestone Payment is payable for subsequent or repeated achievements of the same DT Moderna Target Development and Regulatory Milestone Event with respect to the same Licensed Product (including formulations), or any subsequent Licensed Products with respect to a DT Moderna Target (or multiple targets that include the same DT Moderna Target) for which a DT Moderna Target Development and Regulatory Milestone Event has occurred (see, e.g., the following example set forth in the remainder of this Section 7.8.5 (DT Moderna Target Development Milestones)). By way of example and not limitation, assume that a Licensed Product achieves the first DT Moderna Target Development and Regulatory Milestone Event for the first (1st) DT Moderna Target, and immediately after the Initiation of the Phase II Clinical Trial for such Licensed Product, Moderna decides to discontinue the Development of such Licensed Product Directed Against that DT Moderna Target. In such case, Moderna would pay Metagenomi the Milestone Payment corresponding to the first DT Moderna Target Development and Regulatory Milestone Event set forth in the table above upon the attainment of such DT Moderna Target Development and Regulatory Milestone Event by such Licensed Product. Then, assume that a different Licensed Product for the same DT Moderna Target achieves the first DT Moderna Target

93

Development and Regulatory Milestone Event. In such case, no Milestone Payment is due upon the attainment of the first DT Moderna Target Development and Regulatory Milestone Event with respect to the second Licensed Product, and Moderna would pay Metagenomi the Milestone Payment corresponding to the second DT Moderna Target Development and Regulatory Milestone Event set forth in the table above upon the attainment of such second DT Moderna Target Development and Regulatory Milestone Event by such second Licensed Product. With respect to each DT Moderna Target Development and Regulatory Milestone Event that has two potential options of either (i) or (ii) in the table above, if the first achievement is for the DT Moderna Target Development and Regulatory Milestone Event under clause (ii), and if there is a subsequent achievement for the clause (i) version of the same DT Moderna Target Development and Regulatory Milestone Event, then upon the occurrence of such subsequent achievement the difference between the amount of clauses (i) and (ii) shall be payable. By way of example, if the first Pricing and Reimbursement Approval in the United Kingdom is obtained for a Licensed Product Directed Against a particular DT Moderna Target in an Orphan Indication (a clause (ii) occurrence), then [***] would be owing in accordance with the table above, and if subsequently Pricing and Reimbursement Approval in the United Kingdom is obtained for a Licensed Product Directed Against the same DT Moderna Target in a Non-Orphan Indication, then an additional [***] would be due [***].

Moderna shall provide prompt written notice to Metagenomi upon achievement of a DT Moderna Target Development and Regulatory Milestone Event. Metagenomi shall send an invoice for the applicable Milestone Payment within [***] after receiving the written notice from Moderna.

Within the Term, the other Party shall not more than once each year have the right to have its independent, certified public accountant inspect such Party’s records for the purpose of determining the accuracy of royalty payments for a period covering not more than [***] following the Calendar Quarter to which they pertain. No period shall be audited more than once. The other Party shall submit an audit plan, including audit scope, to such Party for its

102

approval, which shall not be unreasonably withheld, conditioned or delayed, prior to audit implementation. The independent, certified public accountant selected shall keep confidential any information obtained during such inspection and shall report to the Parties 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 such Party. If determined that additional royalties are owed, or that royalties were overpaid, during such period, such Party shall pay the other Party the additional royalties or the other Party shall pay such Party the overpaid royalties, as applicable, within [***] of the date the independent, certified public accountant’s written report is received by the paying Party. The fees charged by the accounting firm of such accountant shall be paid by the auditing Party unless any additional royalties owed exceed [***] and [***] of the royalties paid for the royalty period subject to the audit, in which case the audited Party shall pay the reasonable fees of such accounting firm.

7.15 Default Interest. If and to the extent that either Party fails to make any payment hereunder when due in accordance with the applicable provisions of this Agreement (excluding any payment made due to a good faith error identified via an audit conducted by an independent, certified public accountant pursuant to Section 7.14 (Records and Audits)), such Party shall pay to the other Party default interest at a rate of [***] as from the due date (as reported in The Wall Street Journal (Eastern U.S. edition)) or the maximum rate allowable by Applicable Law, whichever is less.

7.16.2 Cooperation and Coordination. Except as set forth in Section 7.16.1 (Partnership Tax Matters) or Schedule M (Partnership Tax Matters) with respect to the DT Co-Co Program, 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.

103

7.16.3 Payment of Tax. Except as set forth in Section 7.16.1 (Partnership Tax Matters) or Schedule M (Partnership Tax Matters) with respect to the DT Co-Co Program, the upfront, milestones, royalties and other amounts payable by one Party to the other Party under 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 7.16.3 (Payment of Tax), the payee 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 the payor) levied on account of, or measured in whole or in part by reference to, any Payments it receives. The payor shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if the payee is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to the payor or the appropriate Governmental Authority (with the assistance of the payor 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 the payor of its obligation to withhold such tax and the payor shall apply the reduced rate of withholding or dispense with withholding as the case may be; provided that the payor has received evidence, in a form satisfactory to the payor, of the payee’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least [***] prior to the time Payments are due. If in accordance with the foregoing, the payor withholds any amounts of tax, it shall pay to the payee the balance when due, make timely payment to the proper tax authority of the withheld amount and send to the payee proof of such payment within [***] following such payments. If the paying party failed to deduct or withhold tax required by Applicable Law, the payee shall indemnify and hold harmless the paying party from any such taxes and further, shall assist the paying party with regard to all procedures required in order to obtain relief and, if appropriate, reimbursement by tax authorities (including providing proof, if applicable, that the appropriate tax has in fact been paid by the payee) or, in case tax authorities will not reimburse withholding tax to the paying party, the payee will immediately pay to the paying party (for remittance to the appropriate taxing authority to the extent not previously paid to such authorities by the paying party) the amount of such tax not previously paid by the payee to the appropriate taxing authority.

12.2 Termination for Material Breach or Insolvency or Patent Challenge.

12.2.1 Material Breach. On a Program-by-Program basis, subject to Section 12.2.2 (Disputes Regarding Material Breach), each Party (the “Non-Breaching Party”) shall have the right to terminate this Agreement with respect to such Program upon written notice to the other Party (the “Breaching Party”) if the Breaching Party materially breaches its obligations under this Agreement with respect to [***], after receiving written notice from the Non-Breaching Party identifying such material breach by the Breaching Party in reasonable detail, fails to cure such material breach within [***] from the date of such notice (or, if such breach cannot be cured within [***] from the date of such notice, if the Breaching Party has not commenced or is not diligently continuing in good faith efforts to cure such breach; provided that, in any event, such breach must be cured within [***] from the date of such notice) (such [***] period, the “Cure Period”). For the avoidance of doubt, (i) each Party has all rights and may seek all available remedies under Applicable Laws in the event of a breach of this Agreement by the other Party, regardless of whether such breach constitutes a material breach that could give rise to termination of this Agreement, and (ii) if a material breach giving rise to termination under this Section 12.2.1 (Material Breach) is specific to any one (1) or more Programs, then the Non-Breaching Party’s right to terminate under this Section 12.2.1 (Material Breach) shall be limited to such affected Programs.

125

12.2.2 Disputes Regarding Material Breach. If the Parties reasonably and in good faith disagree as to whether there has been a material breach, then the Breaching Party that disputes whether there has been a material breach may contest the allegation in accordance with Article 13 (Governing Law; Dispute Resolution), and the applicable Cure Period shall be tolled upon the initiation of such dispute resolution procedures. If, as a result of such dispute resolution process, it is finally determined pursuant to Article 13 (Governing Law; Dispute Resolution) that the Breaching Party committed a material breach of this Agreement, then the applicable Cure Period shall resume and unless such alleged breach was cured during the pendency of such Cure Period (once resumed), this Agreement shall terminate effective as of the expiration of such Cure Period. This Agreement shall remain in full force and effect during the pendency of any such dispute resolution proceeding and all Cure Periods. Any such dispute resolution proceeding shall not suspend any obligations of either Party hereunder and each Party shall use reasonable efforts to mitigate any damages. Any payments that are made by one Party to the other Party pursuant to this Agreement pending resolution of the dispute shall be promptly refunded if it is determined pursuant to Article 13 (Governing Law; Dispute Resolution) that such payments are to be refunded by one Party to the other Party. If, as a result of such dispute resolution proceeding, it is determined that the Breaching Party did not commit such material breach (or such material breach was cured in accordance with Sections 12.2.1 (Material Breach) or 12.2.2 (Disputes Regarding Material Breach)), then no termination of this Agreement shall be effective, and this Agreement shall continue in full force and effect.

12.2.3 Termination for Insolvency. To the extent permitted by Applicable Laws, either Party may terminate this Agreement in its entirety upon providing written notice to the other Party on or after the time that such other Party files or institutes a bankruptcy, reorganization, liquidation, or receivership proceeding or upon the appointment of a receiver or trustee over all or substantially all property of the other Party, or upon an assignment of a substantial portion of the assets of the other Party for the benefit of creditors; provided that in the case of any involuntary bankruptcy proceeding, such right to terminate shall only become effective if the other Party consents to the involuntary bankruptcy or such proceeding is not dismissed within [***] after the filing thereof.

12.2.4 Termination for Patent Challenge. Metagenomi shall have the right, upon written notice to Moderna, to terminate this Agreement on a Program-by-Program basis if Moderna directly or indirectly (whether alone, or in concert with or for the benefit of any Third Party) challenges, opposes, seeks to invalidate or render void or unenforceable any Patent included within the Metagenomi Licensed Collaboration Technology in such Program, through a declaratory judgment, post grant review, inter partes review, or any other action or proceeding, except to the extent required by Applicable Law, court order or bona fide judicial process.

12.3 Moderna Option to Continue in Lieu of Termination.

12.3.1 Payment Reductions in Lieu of Termination. For a given RT Target or DT Moderna Target (and any related Program or Licensed Products), with respect to Metagenomi’s material breach of any of its obligations under this Agreement with respect thereto as determined pursuant to Section 12.2.1 (Material Breach) (and after completion of the process set forth in Section 12.2.2 (Disputes Regarding Material Breach) if invoked), Moderna shall have the right, at its option and by written notice to Metagenomi, in lieu of exercising its right to terminate this Agreement with respect to such Collaboration Target under Section 12.2.1 (Material Breach), to instead continue this Agreement with respect to such Collaboration Target (and related Program and Licensed Products) in accordance with its terms, and in which case: (a) at Moderna’s

126

option, the JSC will coordinate wind-down of Metagenomi’s activities with respect to such RT Program or DT Program, and (b) from and after such time as Moderna delivers such written notice to Metagenomi, any and all amounts thereafter payable by Moderna for a Licensed Product applicable to such Collaboration Target hereunder (including Milestone Payments and royalties) shall be reduced by fifty percent (50%) (and for clarity, any floors on any such Milestone Payments and royalties hereunder will also be lowered by fifty percent (50%)). Notwithstanding the foregoing, Moderna’s exercise of its rights under this Section 12.3.1 (Payment Reductions in Lieu of Termination) with respect to a Collaboration Target shall not affect the Parties’ respective rights and obligations (including, without limitation, Milestone Payments and royalties) with respect to any other Collaboration Targets (or any related Program or Licensed Products).

12.3.2 Profit-share Reduction in Lieu of Termination. For a given DT Co-Co Target (and related Program and DT Co-Co Products), with respect to Metagenomi’s material breach of any of its obligations under this Agreement with respect thereto as determined pursuant to Section 12.2.1 (Material Breach) (and after completion of the process set forth in Section 12.2.2 (Disputes Regarding Material Breach) if invoked), Moderna shall have the right, at its option and by written notice to Metagenomi, in lieu of exercising its right to terminate this Agreement with respect to such DT Co-Co Target under Section 12.2.1 (Material Breach), to instead continue this Agreement with respect to such DT Co-Co Target (and related Program and DT Co-Co Products) in accordance with its terms, and in which case, Moderna may elect, on a one time basis, by providing a written notice to Metagenomi, to seek to adjust the Profit and Loss Share for one or more DT Co-Co Products for such DT Co-Co Target in the Territory and, to fairly compensate Moderna for the damages arising from such material breach. Moderna will have the right to propose the adjustment, and the Parties will discuss in good faith, and if the Parties cannot mutually agree, then such adjustment shall be resolved pursuant to Section 13.3 (Arbitration). It is understood that such adjustment would provide Moderna with additional share of the net profits (but not more than 75% of the total net profits) for the DT Co-Co Products, to Moderna, for a period of time as may be appropriate and agreed by the Parties (or pursuant to Section 13.3 (Arbitration), as applicable). The profit adjustment may be, with respect to the DT Co-Co Target, on a country-by-country basis, or for the entire Territory, and the adjustment shall not apply to the sharing of any Development Costs. If Moderna so elects, then this Agreement shall continue to be in force with respect to such DT Co-Co Target (and related Program and DT Co-Co Products), provided that the foregoing shall not limit any other rights that Moderna may have under this Agreement with respect to Metagenomi’s material breach, including to seek specific performances pursuant to Section 13.5 (Equitable Relief; Remedy for Breach of Exclusivity).

12.3.3 Know-How Transfer. Within thirty (30) days following Moderna’s election not to terminate this Agreement under this Section 12.3 (Moderna Option to Continue in Lieu of Termination), Metagenomi shall disclose or deliver to Moderna, to the extent not previously provided, copies of all data and information in Metagenomi’s (or its Affiliates’) possession relating to the applicable Program which is reasonably necessary for Moderna’s Research, Development or Commercialization of the applicable Products (including for regulatory purposes and to otherwise undertake Program activities that would otherwise have been performed by Metagenomi and regardless of the stage of any such activities). Upon Moderna’s reasonable request, Metagenomi shall: (a) provide reasonable technical assistance to Moderna during such disclosure or delivery set forth in the preceding sentence; and (b) make its employees and nonemployee consultants reasonably available at their respective places of employment to consult with

127

Moderna on issues arising in the course of Moderna’s Research, Development or Commercialization and in connection with any request related to a Product from any Regulatory Authority, including regulatory, scientific, technical and clinical testing issues. The Know-How transfer to be undertaken under this Section 12.3 (Moderna Option to Continue in Lieu of Termination) shall be overseen by a Working Group established for such purposes, which Working Group may put in place a technology transfer plan expressly identifying Know-How Controlled by Metagenomi or its Affiliates to be transferred and the timing for such transfer.

12.4 Termination for Convenience by Moderna. Moderna may, at any time in its sole discretion and without cause, terminate this Agreement with respect to an RT Program or a DT Program upon at least: (a) sixty (60) days’ prior written notice to Metagenomi if a First Commercial Sale has not occurred for the Products in such Program; or (b) one hundred eighty (180) days’ prior written notice to Metagenomi if a First Commercial Sale of a Product in such Program has occurred.

12.5 Termination for Convenience by Primary Party. Subject to the remainder of this Section 12.5 (Termination for Convenience by Primary Party), the Primary Party may, at any time in its sole discretion and without cause, terminate this Agreement with respect to the DT Co-Co Program upon at least [***] prior written notice to the Opt-Out Party. Upon receiving the written notice from the Primary Party, and within such [***] period, the Opt-Out Party may elect to opt into the DT Co-Co Program to continue the Development and Commercialization activities in the DT Co-Co Program in the Territory by providing written notice to the Primary Party of such election (“Opt-In,” and such right to Opt-In, the “Opt-In Right”). The exercise by the Opt-Out Party of its Opt-In Right in accordance with the foregoing sentence shall become effective [***] after the delivery of the written notice to the Primary Party (the “Opt-In Date”).

12.5.1 If the Opt-Out Party exercises its right to Opt-In with respect to the DT Co-Co Program pursuant to this Section 12.5 (Termination for Convenience by Primary Party), then (i) the DT Co-Co Program shall not terminate, (ii) from and after the Opt-In Date, all rights to lead or manage any of the activities conducted by the Primary Party as of the proposed date of termination set forth in its written notice to the Opt-Out Party under this Section 12.5 (Termination for Convenience by Primary Party) shall be assumed by, and assigned to, the Opt-Out Party, and (iii) the Opt-Out Party shall be referred to as the “Opt-In Party” hereafter in this Section 12.5 (Termination for Convenience by Primary Party).

12.5.2 Subject to Section 12.5.3 (Termination for Convenience by Primary Party), after the Opt-In Party exercises the Opt-In Right with respect to the DT Co-Co Program pursuant to this Section 12.5 (Termination for Convenience by Primary Party), (i) the license of the Licensed DT Co-Co Technology with respect to the DT Co-Co Program from the Opt-In Party to the Primary Party under Section 6.8.2 (Effects of Opt-Out) shall immediately terminate as of the Opt-In Date, and the license of the Licensed DT Co-Co Technology with respect to the DT Co-Co Program from the Primary Party to the Opt-In Party under Section 5.5 (DT Co-Co Program License) shall immediately become effective again and immediately become exclusive (subject to applicable Antitrust Filings and related government approvals or clearances, provided that the Parties shall reasonably cooperate with each other in connection with the Antitrust Filings); (ii) the Opt-In Party shall have sole authority and be solely responsible for all Development and Commercialization activities and related costs in the DT Co-Co Program, provided that in any event Moderna would

128

retain the decision-making power with respect to issues related to CMC Matters, Manufacturing, and the application of Moderna’s technology to any of such activities; (iii) the Parties shall agree upon a written transition plan (an “Opt-In Transition Plan”) setting forth all of the wind-down and other activities necessary or reasonably useful to transition all Development, Commercialization, and Medical Affairs activities, and any accompanying technology transfer activities (including the assignment of any applicable Data Packages), for clarity excluding any transfer of any consulting services with respect to the DT Co-Co Program (collectively, the “Opt-In Transition Activities”); (iv) each Party shall carry out the Opt-In Transition Activities assigned to it in the Opt-In Transition Plan and be responsible for its own costs with respect to such Opt-In Transition Activities; (v) the Primary Party shall assign and transfer (where applicable) to the Opt-In Party all Regulatory Documentations specific to all DT Co-Co Products in the DT Co-Co Program, and shall grant the Opt-In Party a right of reference to all other Regulatory Documentations with respect to such DT Co-Co Products necessary for the further Development and Commercialization thereof, in each case subject to Moderna retaining CMC-related components of such Regulatory Documentations and all other Moderna’s Confidential Information related to CMC Matters, as set forth in the applicable Opt-In Transition Plan; and (vi) each Party shall submit to the applicable Regulatory Authority any filings, letters, and other Regulatory Filings and documentation necessary to effect such assignment and transfer as soon as practicable.

12.5.3 Notwithstanding the foregoing provisions of this Section 12.5 (Termination for Convenience by Primary Party), after Metagenomi exercises its Opt-In Right with respect to the DT Co-Co Program pursuant to this Section 12.5 (Termination for Convenience by Primary Party), (i) the license of the Metagenomi Licensed DT Co-Co Technology with respect to the DT Co-Co Program from Metagenomi to Moderna under Section 6.8.2(b) (Effects of Opt-Out) shall become co-exclusive but Moderna shall only practice its rights under the co-exclusively licensed Metagenomi Licensed DT Co-Co Technology to perform its obligations pursuant to Section 5.23 (Manufacture), and (ii) the license of the Moderna Licensed DT Co-Co Technology with respect to the DT Co-Co Program from Moderna to Metagenomi under Section 5.5 (DT Co-Co Program License) shall become effective again and immediately become non-exclusive after DC Nomination with respect to the DT Co-Co Product nominated in such DC Nomination, provided that (A) Metagenomi may only keep Exploiting Moderna Licensed DT Co-Co Technology being Exploited by Metagenomi as of Metagenomi’s prior Opt-Out Date, and the Exploitation of any other Moderna Licensed DT Co-Co Technology shall be subject to Moderna’s express prior written consent, and (B) Metagenomi may only Exploit mRNA-LNP Technology of Moderna or any of its Affiliates and not of any Third Party.

12.5.4 Notwithstanding anything herein to the contrary, in the event Moderna exercises its Opt-In Right pursuant to this Section 12.5 (Termination for Convenience by Primary Party), the JSC and its subcommittees, except to the extent required by the Opt-In Transition Plan to facilitate the Opt-In Transition Activities, shall immediately disband, for clarity, solely with respect to such DT Co-Co Program.

12.5.5 Notwithstanding anything herein to the contrary, in the event Metagenomi exercises its Opt-In Right pursuant to this Section 12.5 (Termination for Convenience by Primary Party), then Section 6.5.1(c) (CMC Matters) and Section 5.23 (Manufacture) shall remain in force. After Metagenomi has exercised such Opt-In Right, the Parties will use Commercially Reasonable Efforts to negotiate and enter a supply agreement and a quality agreement covering the supply of Candidates and Products for Research, Development, and Commercialization, as applicable, for such DT Co-Co Program.

129

12.5.6 Notwithstanding anything herein to the contrary, in the event Metagenomi exercises its Opt-In Right pursuant to this Section 12.5 (Termination for Convenience by Primary Party), if not previously prepared and filed, Moderna will, at Metagenomi’s written request, prepare and file with Regulatory Authorities in jurisdictions where Metagenomi is seeking Regulatory Approval of a DT Co-Co Product, a DMF containing required CMC information for such DT Co-Co Product’s Regulatory Approval. Metagenomi and its Affiliates may refer to such DMF in any Regulatory Filing made in connection with obtaining or maintaining a Regulatory Approval for such DT Co-Co Product. Moderna will, on written request by Metagenomi or its Affiliate, provide to such requesting party and to any specified Regulatory Authority a letter, in the form reasonably required by such requesting party, acknowledging that the requesting party has a right of reference to any such DMF. Notwithstanding that the foregoing provisions of this Section 12.5.6 (Termination for Convenience by Primary Party) provide the mechanism for Regulatory Authorities to have required access to Moderna’s CMC information, in the event that the procedures set forth in the foregoing provisions of this Section 12.5.6 (Termination for Convenience by Primary Party) are not available in a particular country or are not sufficient to satisfy a Regulatory Authority’s requirements, at Metagenomi’s request, the Parties will discuss such requirements and use Commercially Reasonable Efforts to secure agreement from the Regulatory Authority for it to receive required access to all necessary CMC information directly from Moderna in a manner that minimizes the disclosure of such CMC information and protects the confidential and proprietary nature of such CMC information. Notwithstanding the foregoing provisions of this Section 12.5.6 (Termination for Convenience by Primary Party), Moderna shall have no obligation to comply with Metagenomi’s or its Affiliates’ written request that Moderna prepare and file a DMF with, or otherwise provide CMC information to, any Regulatory Authority in any jurisdiction with respect to which Moderna has a material concern regarding the protection of its intellectual property rights in connection with any Regulatory Filing or otherwise seeking or maintaining any Regulatory Approval in such jurisdiction, and upon written request by Moderna, Metagenomi shall, and shall cause its Affiliates and its and their Sublicensees to, refrain from preparing or submitting any Regulatory Filing, or otherwise obtaining or maintaining any Regulatory Approval, for any DT Co-Co Product in such jurisdictions.

12.6 Effects of Termination.

12.6.1 Effects of termination generally. Subject to the remainder of this Section 12.6 (Effects of Termination), upon termination of this Agreement with respect to a Program, with respect to Products within such Program, on a Product-by-Product basis:

All licenses granted hereunder with respect to such Product will terminate; provided that such licenses will continue as necessary for the Parties to complete the orderly wind-down of their activities under this Agreement in accordance with Applicable Law and as otherwise required in accordance with Section 12.6.1(b) (Wind Down). With the exception of such wind-down activities, each Party shall immediately cease and shall cause its Affiliates, Sublicensees and contractors, each as applicable, to immediately cease, all Research, Development, Manufacturing and Commercialization activities with respect to such Product.

130

(b) Wind-Down. Promptly following receipt by the applicable Party of a notice of termination under Section 12.2 (Termination for Material Breach or Insolvency or Patent Challenge) or Section 12.4 (Termination for Convenience by Moderna) or Section 12.5 (Termination for Convenience by Primary Party) if the Opt-Out Party does not exercise the Opt-In Right, the Parties will begin to wind-down their respective activities under this Agreement with respect to such Product. The Parties will establish an appropriate Working Group to coordinate such wind-down.

(c) Destruction of Confidential Information. Each Receiving Party shall destroy (at the Disclosing Party’s written request) all such Confidential Information of the Receiving Party in its possession as of the effective date of expiration or termination (with the exception of one copy of such Confidential 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 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 Information of the Disclosing Party to the extent necessary to exercise any surviving rights, licenses or obligations under this Agreement. Notwithstanding the foregoing, a Receiving Party shall not be required to destroy any computer files created during automatic system back up that are subsequently stored securely by it and not readily accessible to its employees, consultants, or others who received the Disclosing Party’s Confidential Information under this Agreement.

12.6.2 Reversion. Upon termination of this Agreement with respect to a Program by Metagenomi under Section 12.2.1 (Material Breach), with respect to any Product within such Program impacted by Moderna’s material breach (a “Reversion Product”), the following will occur:

(a) any licenses and rights granted by Metagenomi to Moderna with respect to the Reversion Product shall revert to Metagenomi, provided that such licenses and rights will continue as necessary as otherwise required under this Section 12.6.2 (Reversion);

(b) in the case the Reversion Product is a DT Co-Co Product, [***];

(c) effective on the effective date of termination for such Reversion Product, Moderna hereby assigns to Metagenomi or its designee all Regulatory Filings (except DMFs), Regulatory Approvals, Pricing and Reimbursement Approvals, copies of material correspondence and conversation logs, pre-clinical and clinical study reports, clinical study protocols, and all data (in the format in which is maintained by Moderna), in each case, that are related to the Reversion Product and Controlled by Moderna or its Affiliates as of the effective date of termination. Moderna shall take all steps necessary to transfer to Metagenomi or its designee ownership of all such assigned Regulatory Filings (except DMFs), Regulatory Approvals and Pricing and Reimbursement Approvals, including submitting to each applicable Regulatory Authority a letter or other necessary documentation (with a copy to Metagenomi) notifying such Regulatory Authority of the transfer of such ownership of each Regulatory Filing, Regulatory

131

Approval and Pricing and Reimbursement Approval. If it is not feasible under Applicable Laws for Moderna to transfer to Metagenomi any such Regulatory Filings, Regulatory Approvals, and Pricing and Reimbursement Approvals, Moderna shall hold such Regulatory Filings, Regulatory Approvals, and Pricing and Reimbursement Approvals in its name for the benefit of Metagenomi and shall grant, and hereby does grant to Metagenomi an exclusive, royalty-free license and right of reference to use such Regulatory Filings, Regulatory Approvals, and Pricing and Reimbursement Approvals in connection with Exploitation of the Reversion Product and authorize Metagenomi or its designee to conduct regulatory activities with appliable Regulatory Authorities relating to such Regulatory Filings, Regulatory Approvals, and Pricing and Reimbursement Approvals; and

(d) Moderna shall be entitled, during the [***] following the effective date of termination of this Agreement with respect to a Reversion Product, to finish any work-in-progress and to sell any inventory of such Reversion Product and shall pay Metagenomi the amounts applicable to such sales of such Reversion Product in accordance with the terms and conditions of this Agreement. Thereafter, Moderna shall cease selling any such Reversion Product, and Metagenomi shall have the right, in its sole discretion and upon written notification to Moderna, to purchase from Moderna any or all of the inventory of such Reversion Product held by Moderna as of the date of such notice at a price equal to Moderna’s Manufacturing Costs for such Reversion Product.

12.6.3 Conduct During Termination Notice Period. Following any notice of termination permitted under this Article 12 (Term & Termination) other than any termination pursuant to Section 12.2.1 (Material Breach), during any applicable termination notice period (the applicable “Termination Notice Period”), each Party shall continue to perform all of its obligations under this Agreement then in effect in accordance with the terms and conditions of this Agreement. In such circumstances, each Party shall also continue to bear its share of all applicable costs incurred during the Termination Notice Period.

12.6.4 Transition Agreement. In connection with the termination of this Agreement, the Parties shall enter into a written agreement (the “Transition Agreement”) that would include other reasonable terms and conditions, including terms allocating costs and expenses, describing the Parties’ indemnification obligations, setting forth the Parties’ obligations with respect to unauthorized sales, and setting forth other coordination obligations. If, despite such efforts, the Parties are unable to agree upon such terms and conditions within [***] from the effective date of the termination, either Party may refer the dispute for resolution by arbitration in accordance with Article 13 (Governing Law; Dispute Resolution), and the arbitrator shall have the authority to require the Parties to execute a Transition Agreement in the form approved by the arbitrator.

12.6.5 Sublicense Survival. Any permitted sublicense granted by a Party or its Affiliate to a Third Party under the licenses granted to such Party under this Agreement shall survive the termination of this Agreement; provided that, in the case where termination of this Agreement for such Party’s uncured material breach pursuant to Section 12.2.1 (Material Breach), such Sublicensee did not cause such uncured material breach. If permitted under such a surviving sublicense, effective upon termination of this Agreement, such sublicense shall become a direct license from Metagenomi to such Sublicensee.

132

12.7 Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation or right accruing prior to such expiration or termination. Except as set forth below or elsewhere in this Agreement, the obligations and rights of the Parties under the following provisions of this Agreement shall survive expiration or termination of this Agreement: Article 1 (Definitions) (to the extent the definitions are used in surviving provisions); Sections 3.7.1 (Records), 3.7.3 (Ownership; Confidentiality), 4.8.1 (Records), and 4.8.3 (Ownership; Confidentiality); the second and third last sentences of Section 5.18 (Collaboration Materials Transfer); Sections 5.19 (No Other Rights and Retained Rights), 5.25 (Payments); 7.6 (Accounting; Audit), 7.7 (Disputed Payments), 7.13(Method of Payment; Foreign Exchange), 7.14 (Records and Audits), 7.15 (Default Interest), 7.16 (Taxes), 8.1 (Ownership of Intellectual Property), 8.2.1 (Generally), 8.3.2 (Generally), 8.7 (Common Interest), 8.8 (Trademarks), and 9.6 (Disclaimer); Articles 10 (Indemnification) and 11 (Confidentiality); Sections 12.6 (Effects of Termination), 12.7 (Survival), and 12.8 (Bankruptcy Code); Article 13 (Governing Law; Dispute Resolution); and Sections 14.1 (Entire Agreement; Amendment), 14.2 (Limitation of Liability), 14.3 (Independent Contractors), 14.4 (Notices), 14.5 (Severability), 14.6 (Non-Use of Names), 14.13 (Waivers), 14.15 (Interpretation), 14.18 (No Third Party Beneficiary Rights), 14.19 (Construction), 14.20 (Cumulative Remedies), 14.21 (Extension to Affiliates), and 14.22 (Other Activities).

12.8 Bankruptcy Code. If this Agreement is rejected by a Party as a debtor under Section 365 of the U.S. Bankruptcy Code or similar provision in the bankruptcy laws of another jurisdiction (the “Code”), then, notwithstanding anything else in this Agreement to the contrary, all licenses and rights to licenses granted under or pursuant to this Agreement by the Party in bankruptcy to the other Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the Code (or similar provision in the bankruptcy laws of the jurisdiction), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Code (or similar provision in the bankruptcy laws of another applicable jurisdiction). The Parties agree that a Party that is a licensee of rights under this Agreement shall retain and may fully exercise all of its rights and elections under the Code, and that upon commencement of a bankruptcy proceeding by or against a Party under the Code, the other Party shall be entitled to a complete duplicate of, or complete access to (as such other Party deems appropriate), any such intellectual property and all embodiments of such intellectual property, if not already in such other Party’s possession, shall be promptly delivered to such other Party: (a) upon any such commencement of a bankruptcy proceeding upon written request therefor by such other Party, unless the bankrupt Party elects to continue to perform all of its obligations under this Agreement; or (b) if not delivered under the foregoing clause (a), upon the rejection of this Agreement by or on behalf of the bankrupt Party upon written request therefor by the other Party. The foregoing provisions of this Section 12.8 (Bankruptcy Code) are without prejudice to any rights a Party may have arising under the Code.

Article 13

GOVERNING LAW; DISPUTE RESOLUTION

13.1 Governing Laws. This Agreement is governed by and shall be construed in accordance with the laws of the State of New York, without reference to its conflict of laws principles. The United Nations Convention of International Contracts on the Sale of Goods (the Vienna Convention) does not apply to this Agreement.

133

13.2 Disputes. The Parties recognize that controversies or claims arising out of, relating to, or in connection with this Agreement may arise from time to time. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties shall follow the procedures set forth in this Article 13 (Governing Law; Dispute Resolution) to resolve any dispute. If any dispute, claim or controversy of any nature arising out of or relating to this Agreement, including any action or claim based on tort, contract or statute, or concerning the interpretation, effect, termination, validity, performance or breach of this Agreement (each, a “Dispute”), arises between the Parties, either Party may refer the Dispute to Executive Officers of each Party for resolution within [***] of a written request by either Party to the other Party. Each Party, within [***] after a Party has received such written request from the other Party to so refer such Dispute, shall notify the other Party in writing of the Executive Officer to whom such Dispute is referred. If, after an additional [***] after the notice of Dispute, such Executive Officers have not succeeded in negotiating a resolution of the Dispute, and a Party wishes to pursue the matter, each such Dispute, controversy or claim that is not an “Excluded Claim” (defined in Section 13.6 (Excluded Claims)) shall be submitted for binding arbitration administered by the International Chamber of Commerce (“ICC”) pursuant to its Arbitration Rules in effect at the time such Dispute arises (the “ICC Arbitration Rules”). The option to arbitrate under this Article 13 (Governing Law; Dispute Resolution) shall extend to any claims by or against the Parties and their respective Affiliates and any agents, principals, officers, directors, or employees of either of the Parties or their respective Affiliates.

13.3 Arbitration. Any arbitration that the Parties decide to pursue shall be conducted by a single neutral arbitrator experienced in the business of pharmaceuticals. If the issues in dispute involve scientific, technical or commercial matters, the arbitrator chosen hereunder may engage experts that have educational training or industry experience sufficient to demonstrate a reasonable level of relevant scientific, medical and industry knowledge, as necessary to help resolve the dispute. The Parties shall select the arbitrator promptly following the initiation of the arbitration. If the Parties are unable or fail to agree upon the arbitrator within [***] following the initiation of arbitration, the arbitrator shall be appointed by ICC. The arbitration shall be conducted in New York, New York, and all proceedings and communications shall be in English. Except to the extent necessary to enforce a legal right or as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties. Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrator’s fees and any administrative fees of arbitration. Any arbitration findings or rulings made under this Section 13.3 (Arbitration) shall be final and binding on the Parties.

13.4 Baseball Arbitration. Any Disputes over any amounts invoiced under this Agreement, Disputes over matters set forth in Sections 2.10.2 (Decision-making for DT Co-Co Plans), 5.10.3(b) (Payments under Co-Co Moderna In-License Agreements), 5.10.4(b) (Payments under Co-Co Metagenomi In-License Agreements) and 12.6.2(b) (Reversion), shall be submitted to and finally resolved by the following provisions in this Section 13.4 (Baseball Arbitration). The Parties shall promptly designate in writing a single mutually acceptable arbitrator experienced in the licensing, development, and commercialization of pharmaceutical products, who is independent of each Party (i.e., not a current or former employee, consultant, officer, or director or current stockholder of either Party or their respective Affiliates and who does not otherwise have any current or previous business relationship with either Party or their respective Affiliates). If the Parties cannot agree on an arbitrator within [***] after referral of such matter, the arbitrator shall be selected by the President of Greater Boston Chamber of Commerce. The arbitration shall

134

be conducted in accordance with the ICC Arbitration Rules to the extent consistent with this Section 13.4 (Baseball Arbitration). Within [***] of the arbitrator’s appointment, each Party shall prepare and deliver to both the arbitrator and the other Party its last, best offer for the applicable unresolved terms and a memorandum in support thereof. The Parties shall also provide the arbitrator with a copy of the relevant provisions of this Agreement. Each Party may submit to the arbitrator (with a copy to the other Party) a rebuttal to the other Party’s support memorandum and shall at such time have the opportunity to amend its last such offer based on any new information contained in the other Party’s support memorandum. Within [***] after the arbitrator’s appointment, the arbitrator shall select from the two (2) proposals provided by the Parties the proposal such arbitrator believes is the most consistent with the intent of the Parties when this Agreement was entered into provided the arbitrator may not alter the terms of this Agreement. The decision of the arbitrator shall be final and binding on the Parties. The foregoing “baseball-style” arbitration shall be the exclusive remedy of either Party if the Parties cannot agree on any Disputes over any amounts invoiced under this Agreement, or Disputes over matters set forth in Sections 2.10.2 (Decision-making for DT Co-Co Plans), 5.10.3(b) (Payments under Co-Co Moderna In-License Agreements), 5.10.4(b) (Payments under Co-Co Metagenomi In-License Agreements) and 12.6.2(b) (Reversion).

13.5 Equitable Relief; Remedy for Breach of Exclusivity. Nothing in this Article 13 (Governing Law; Dispute Resolution) shall preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding. Therefore, in addition to its rights and remedies otherwise available at law, including the recovery of damages for breach of this Agreement, such Non-Breaching Party shall be entitled to seek (a) equitable relief, specifically including, but not limited to, both interim and permanent restraining orders and injunctions and (b) such other and further equitable relief as the court may deem proper under the circumstances. Any final judgment resolving a Dispute may be enforced by either Party in any court having appropriate jurisdiction. For the avoidance of doubt, nothing in this Section 13.5 (Equitable Relief; Remedy for Breach of Exclusivity) shall otherwise limit a Breaching Party’s opportunity to cure a material breach as permitted in accordance with Section 12.2.1 (Material Breach).

13.6 Excluded Claims. As used in this Article 13 (Governing Law; Dispute Resolution), the term “Excluded Claim” means any dispute, controversy or claim that concerns: (a) the validity, enforceability or infringement of any patent, trademark or copyright; or (b) any antitrust, antimonopoly or competition law or regulation, whether or not statutory. Any Excluded Claim may be submitted by either Party to any court of competent jurisdiction over such Excluded Claim.

Article 14

135

understandings between the Parties with respect to the subject matter hereof, including the Mutual Confidentiality Agreement. The Parties hereby agree to terminate the Mutual Confidentiality Agreement as of the Effective Date, and that all confidential information that was disclosed by the Parties pursuant to the Mutual Confidentiality Agreement shall be deemed Confidential Information disclosed under, and subject to, the terms and conditions of this Agreement.

No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party.

14.2 Limitation of Liability.

All remaining portions shall remain in full force and effect.

14.6 Non-Use of Names. Metagenomi shall not use the name, trademark, logo, or physical likeness of Moderna or its respective officers, directors or employees, or any adaptation of any of them, in any advertising, promotional or sales literature, without Moderna’s prior written consent.

14.7 Assignment. 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 14.9 (Metagenomi Change of Control). 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 is binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the terms of this Section 14.7 (Assignment) is null, void and of no legal effect.

137

14.8 Acquisition of Existing Competing Programs. If, after the Effective Date, any Third Party becomes an Affiliate of a Party that such Party controls (as such term is defined in the definition of “Affiliate”, and for clarity, excluding a New Affiliate) 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) the Development or Commercialization of any compound or product; or (b) the licensing, conveyance, sublicensing or other grant of rights in Patents or Know-How with respect to such any compound or product, in each case of (a) and (b) that would, if conducted by such Party, cause such Party to breach its exclusivity obligations set forth in Section 5.20 (RT Exclusivity), Section 5.21 (DT Exclusivity), Section 5.22 (DT Co-Co Target Exclusivity) (any 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 [***] following the earlier of the first public announcement of such transaction or the execution of a definitive agreement relating to such transaction (if such disclosure is not prohibited under Applicable Laws), and such Party does (or causes such Affiliate to), within [***] after the closing of such transaction, with mutual agreement with the other Party, either: (i) complete a Divestiture of such Competing Program; (ii) cease and terminate the Competing Program, subject to any commercially reasonable wind-down provisions, including with respect to Clinical Trials; or (iii) offer to include the Competing Program into this Agreement; provided that the actions in clauses (i) – (iii) will not have to occur if such Third Party has pre-existing license or contractual obligation that would prohibit the Third Party from taking the actions in clauses (i) – (iii).

14.9 Metagenomi Change of Control.

14.9.1 Notification of Change of Control. If Metagenomi undergoes a Change of Control at any time before expiry of the Research Term, Metagenomi shall provide Moderna with written notice of such Change of Control of Metagenomi 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 (if such disclosure is not prohibited under Applicable Law or by the terms of any written agreement between Metagenomi and any Third Party), which notice shall describe in reasonable detail the nature of the transaction and the identity of the Acquirer (a “Change of Control Notice”). If Metagenomi undergoes such a Change of Control, then Section 14.9.2 (Effects of Change of Control) shall apply. For the avoidance of doubt, a Change of Control of Metagenomi shall not in any way limit or alter Moderna’s rights in accordance with Section 12.3 (Moderna Option to Continue in Lieu of Termination).

14.9.2 Effects of Change of Control. On a Program-by-Program basis, following a Change of Control of Metagenomi at any time before expiry of the Research Term for such Program, Moderna may elect, at its sole discretion, whether the Research Transfer Scenario (in subsection (a) below) or the Research Continuance Scenario (in subsection (b) below) shall apply to such Change of Control.

(a) Research Transfer Scenario. The “Research Transfer Scenario” means that Metagenomi shall, on a Program-by-Program basis, transfer to Moderna all ongoing Research and Development activities (including the data and results for such Program), if any, being conducted by or on behalf of Metagenomi or any of its Affiliates, or if no Research or Development activities remain ongoing at the time of such Change of Control, the following shall apply:

138

(i) Metagenomi shall promptly disclose or deliver to Moderna, to the extent not previously provided, copies of all data, results, and information in Metagenomi’s (or its Affiliates’) possession constituting Know-How included in the Metagenomi Licensed Collaboration Technology, which is reasonably necessary or useful for Moderna’s Exploitation of the Candidates and the Products (including for regulatory purposes) in such Program, and upon Moderna’s reasonable request and at Moderna’s expense, Metagenomi will: (A) provide reasonable technical assistance to Moderna during such disclosure or delivery set forth in the preceding sentence for a period not longer than [***]; and (B) make its employees and non-employee consultants reasonably available at their respective places of employment to consult with Moderna on issues arising in the course of Moderna’s Exploitation or in connection with any request related to a Product from any Regulatory Authority, including regulatory, scientific, technical and clinical testing issues, preparation and submission of Regulatory Filings, and assistance in responding to requests from Regulatory Authorities (the “Know-How Transfer”). The Know-How Transfer to be undertaken under the foregoing shall be overseen by a Working Group established for such purposes, which Working Group may put in place a transfer plan expressly identifying Know-How owned or Controlled by Metagenomi or its Affiliates to be transferred and the timing for such transfer; and

(ii) the JSC shall be immediately disbanded, and all approval rights of the JSC, or final decision making authority granted to a Party pursuant to this Agreement, shall become approval rights of the corresponding Party (i.e., mutual agreement by the Parties or final decision making authority by a Party).

(b) Research Continuance Scenario. The “Research Continuance Scenario” means, on a Program-by-Program basis, that Metagenomi shall continue the Research and other activities, if any, being conducted under the applicable Program Plan, and the Program and this Agreement shall continue in the same manner as prior to the Change of Control, and in which case: (i) Moderna will maintain all of its rights under this Agreement; and (ii) Metagenomi shall continue to comply with its diligence obligations hereunder, with the same level of diligence applied to such activities after the consummation of such Change of Control as compared to prior to the consummation of such Change of Control.

14.10 Acquirer Engaged in Competing Program. On a Program-by-Program basis, if a Party undergoes a Change of Control at any time before expiry of the Term for such Program and, as of the closing date of such Change of Control transaction or thereafter, the Acquirer (or any of its Affiliates) is engaged in a Competing Program, then such Party shall implement (as of the closing of such transaction or the engagement in the Competing Program, if later than the closing of such transaction) and enforce Firewalls for the duration of the Firewall Period.

14.11 Firewalled Programs. Promptly following the first to occur of any of the following events in relation to an Acquirer of a Party during the Term: (a) the effective date of a Change of Control of such Party to an Acquirer with a Competing Program, or (b) DC Nomination (if applicable), in either case (a) or (b) that results in the Acquirer’s program with respect to the applicable Collaboration Target becoming a Competing Program, or (c) the initiation of a Competing Program by an Acquirer of such Party (each of (a), (b), and (c), with respect to such Competing Program, the “Firewall Event”), such Party shall implement and enforce Firewalls between the applicable Program and the Competing Program for the duration of the applicable Firewall Period.

139

14.12 Firewall Audits. In the event a Party is obligated to implement and enforce Firewalls under this Agreement, the other Party shall have the right, through a designated Third Party auditor reasonably acceptable to such Party, to audit such Party’s (and, as applicable, its Affiliates’) obligations under this Agreement regarding implementation and enforcement of such Firewalls for purposes of confirming compliance with the Firewalls, identifying any vulnerabilities or breaches and requiring such Party (or its Affiliates) to promptly remediate any non-compliance identified by such audit. In connection with such audit, duly authorized representatives of the other Party’s designated auditor may make an on-site visit to such Party (or its Affiliate) for the purpose of conducting such audit. The other Party may conduct such audits from time to time as reasonably necessary to confirm such Party’s compliance with such Firewall requirements no more than [***] or more frequently if the other Party reasonably believes at any time that such Party is not in compliance with such Firewall requirements; provided that if the auditor identifies a breach of the Firewall, the other Party will be entitled to up to [***] additional audits within the same Calendar Year to verify that appropriate action has been taken to remedy the breach of the Firewall. Any audits described under this Section 14.12 (Firewall Audits) shall be conducted during such Party’s regular business hours, for a duration only as reasonably necessary to confirm such Party’s compliance with the applicable Firewall requirements, and shall not unreasonably interfere with or impede such Party’s business operations. The other Party shall provide such Party with written notice of such audit at least [***] prior to such requested audit (or such shorter period as may be designated by the other Party if the other Party reasonably believes at any time that such Party is not in compliance with such Firewall requirements). All such audits shall be conducted at the other Party’s cost and expense. If the auditor identifies any breach of the Firewall, the other Party or the auditor will notify such Party, and such Party will promptly (and will use reasonable efforts to ensure its Affiliates promptly) take all action necessary to remedy such breach, and will provide the other Party with reasonable assurance that such action has been taken, at such Party’s sole expense.

14.13 Waivers. 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.

14.14 Force 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, pandemics, 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 shall keep the other Party informed of actions related thereto.

140

Unless specified to the contrary, references to Articles, Sections or Schedules mean the particular Articles, Sections or Schedules to this Agreement and references to this Agreement include all Schedules hereto. In the event of any conflict between the main body of this Agreement and any Schedule hereto, the main body of this Agreement shall prevail. Unless context otherwise clearly requires, whenever used in this Agreement: (a) the words “include” or “including” shall be construed as incorporating, also, “but not limited to” or “without limitation”; (b) the word “or” is used in the inclusive sense (i.e., “and/or”); (c) the word “day” or “year” means a calendar day or year unless otherwise specified; (d) the word “notice” means notice in writing (whether or not specifically stated) and shall include notices, consents, approvals and other written communications contemplated under this Agreement; (e) the words “hereof,” “herein,” “hereby” and derivative or similar words refer to this Agreement as a whole and not merely to the particular provision in which such words appear; (f) the words “shall” and “will” have interchangeable meanings for purposes of this Agreement; (g) provisions that require that a Party, the Parties or a committee hereunder “agree,” “consent” or “approve” or the like shall require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter, approved minutes or otherwise; (h) words of any gender include the other gender; (i) words using the singular or plural number also include the plural or singular number, respectively; (j) references to any specific law, rule or regulation, or article, section or other division thereof, shall be deemed to include the then-current amendments thereto or any replacement law, rule or regulation thereof; (k) the phrase “non-refundable, non-creditable” shall not prohibit, limit or restrict either Party’s right to obtain damages in connection with a breach of this Agreement; and (l) neither Party shall be deemed to be acting on behalf of the other Party.

14.16 Expenses. Each Party shall pay its own costs, charges and expenses incurred in connection with the negotiation, preparation and execution of this Agreement.

14.17 Further Assurances. Moderna and Metagenomi hereby covenant and agree without the necessity of any further consideration, to execute, acknowledge and deliver any and all documents and take any action as may be reasonably necessary to carry out the intent and purposes of this Agreement.

14.18 No Third Party Beneficiary Rights. This Agreement is not intended to and shall not be construed to give any Third Party any interest or rights (including any Third Party beneficiary rights) with respect to or in connection with any agreement or provision contained herein or contemplated hereby, except for Third-Party Indemnitees or as otherwise expressly provided for in this Agreement.

14.19 Construction. The Parties hereto acknowledge and agree that: (a) each Party and its counsel reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; (b) the rule of construction to the effect that any ambiguities are resolved against the drafting Party shall not be employed in the interpretation of this Agreement; and (c) the terms and provisions of this Agreement shall be construed fairly as to all Parties hereto and not in a favor of or against any Party, regardless of which Party was generally responsible for the preparation of this Agreement.

141

14.20 Cumulative Remedies. No remedy referred to in this Agreement is intended to be exclusive unless explicitly stated to be so, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under law.

14.21 Extension to Affiliates. Except as expressly set forth otherwise in this Agreement, each Party shall have the right to extend the rights and immunities granted in this Agreement to one or more of its Affiliates. All applicable terms and provisions of this Agreement, except this right to extend, shall apply to any such Affiliate to which this Agreement has been extended to the same extent as such terms and provisions apply to the Party extending such rights and immunities. For clarity, a Party extending the rights and immunities granted hereunder shall remain primarily liable for any acts or omissions of its Affiliates.

14.22 Other Activities. Except as expressly provided in this Agreement, each Party may: (a) engage in research, manufacturing, development or commercialization activities that utilize technologies similar to or involve products competitive with those contemplated under this Agreement; and (b) use any publicly available information and research results (including any publicly available information of the other Party) to the same extent as Third Parties generally are legally permitted to do so. Except as expressly provided in this Agreement, nothing in this Agreement, including any obligation to promote Products or any restriction on the use of Confidential Information, shall create: (i) any obligation not to research, develop, manufacture, commercialize or otherwise exploit any product; or (ii) any obligation to utilize a Sales Force for Products separate from sales forces for other products.

Schedule J

Co-Co Products Profit and Loss Share

This Schedule J (Co-Co Products Profit and Loss Share) covers financial planning, accounting policies and procedures to be followed in determining the Co-Co Products Profit and Loss Share with respect to the DT Co-Co Products in the Territory.

1. Principles of Reporting.

1.1 Each Party shall provide a report of the results of its operations for the applicable period with respect to Commercialization, Medical Affairs and other related activities in the Territory for each DT Co-Co Product, which report shall include the cost categories set forth below. Following receipt of each such report from the Parties, Moderna shall generate a consolidated report, for each DT Co-Co Product in the Territory, based on the foregoing financial information provided by each Party, which report shall be in the following format (the “P&L”):

Cost Category |  | Moderna |  |  | Metagenomi |  |  | Total |
Net Sales |  |  |  |  |  |  |  |  |  |  |  |
less Cost of Sales |  |  |  |  |  |  |  |  |  |  |  |
plus Licensing Income |  |  |  |  |  |  |  |  |  |  |  |
less Eligible Medical Affairs Costs |  |  |  |  |  |  |  |  |  |  |  |
less Commercialization Costs |  |  |  |  |  |  |  |  |  |  |  |
less Other Operating Expenses |  |  |  |  |  |  |  |  |  |  |  |
= Operating Profits or Losses |  |  |  |  |  |  |  |  |  |  |  |

1.2 Standards. It is the intention of the Parties to interpret each of the definitions used in the P&L in a manner that is consistent with this Schedule J (Co-Co Products Profit and Loss Share) and applicable U.S. GAAP principles; it being understood and agreed that “Operating Profits or Losses” shall be calculated in accordance with applicable U.S. GAAP principles. Each Party agrees to provide reasonable supporting documentation to ensure that each Party’s accounting methodologies are reasonable and consistently applied. Reasonable methodologies may include a standard rate or some other appropriate basis for allocating costs. Notwithstanding anything herein to the contrary, in no event shall either Party be obligated to recognize revenue for its own purposes in a manner that is contrary to the U.S. GAAP principles used by such Party.

Schedule J-1

1.3 Accounting Procedures. Each Party shall record and account for its Eligible Medical Affairs Costs, Commercialization Costs or Other Operating Expenses, in each case, in a manner that allocates costs to the extent possible to a specific activity in the applicable Medical Affairs Budget, Commercialization Budget or specific category of Other Operating Expenses. For purposes of determining Net Sales, Licensing Income, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, or Other Operating Expenses, any expense allocated by either Party to a particular category under the definition of Net Sales, Licensing Income, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, or Other Operating Expenses shall not be allocated to any other category under the definition of Net Sales, Licensing Income, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, or Other Operating Expenses, respectively. Each Party shall determine Net Sales, Licensing Income, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, and Other Operating Expenses using its standard accounting procedures, consistently applied and consistent with U.S. GAAP principles, to the maximum extent practicable as if the applicable DT Co-Co Product were a solely-owned product of such Party (provided that the application of such procedures results, on balance, in outcomes that are fair and equitable to both Parties taking into consideration the interests of both Parties as reflected in this Agreement). The Parties recognize that such procedures may change from time to time and that any such changes may affect the calculation of Net Sales, Licensing Income, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, or Other Operating Expenses. Where the change is or would be material to the other Party, the Party proposing to make the change shall provide the other Party with an explanation of the proposed change and an estimate of the effect of the change on the relevant cost or expense category.

1.4 If necessary, a Party shall make the appropriate adjustments to the financial information it supplies under this Schedule J (Co-Co Products Profit and Loss Share) to conform with the format of reporting results of operation required for the P&L. The Parties understand that all Net Sales of each DT Co-Co Product shall be booked in accordance with the Selling Party’s U.S. GAAP principles and otherwise in accordance with Section 1.121 (Net Sales).

2. Frequency of Reporting.

In order to prepare the consolidated P&L, each Party shall submit to the other Party a financial statement of such Party’s Commercialization and Medical Affairs activities, Net Sales, Licensing Income, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, and Other Operating Expenses in the format of the P&L within [***] after the end of [***]. Each such individual P&L shall specify in reasonable detail all categories of actual costs related to Eligible Medical Affairs Costs, Commercialization Costs and Other Operating Expenses, and, upon a Party’s request the other Party shall promptly provide any invoices or other supporting documentation for any External Costs or with respect to which documentation is otherwise reasonably requested. Within [***] after the last day of each Calendar Quarter, Moderna shall prepare a reconciliation report and send it to Metagenomi. Within [***] after the end of each Calendar Quarter, the Parties shall agree on a consolidated P&L for the applicable Calendar Quarter and for such Calendar Quarter, a consolidated reporting of the Operating Profits or Losses, the calculation of the Operating Profits or Losses, and the applicable sharing and determination of the corresponding cash settlement in an agreed format (such report, the “Consolidated Report”).

Within [***] after the end of each Calendar Quarter, whichever Party is owed a payment shall prepare an invoice for such payment and deliver such invoice to the other Party. The paying Party shall pay such invoice within [***] after receipt of the invoice. For clarity, the first P&L prepared with respect to each DT Co-Co Product shall be prepared for the first Calendar Quarter in which either Party incurs Eligible Medical Affairs Costs, Commercialization Costs, or Other Operating

Schedule J-2

Expenses (regardless of whether such Eligible Medical Affairs Costs, Commercialization Costs, or Other Operating Expenses are incurred before or after Regulatory Approval for any DT Co-Co Product). In addition to the above, within [***] after the last day of the [***] of every Calendar Quarter, each Party shall submit to the other Party a report, with respect to each DT Co-Co Product, setting forth the P&L representing for each DT Co-Co Product (if any) the actual Net Sales, Cost of Sales, Licensing Income, Eligible Medical Affairs Costs, Commercialization Costs, and Other Operating Expenses recognized by such Party in such just-completed two month period as well as an estimate of expected Net Sales, Cost of Sales, Licensing Income, Eligible Medical Affairs Costs, Commercialization Costs, and Other Operating Expenses to be recognized in the third month of the current Calendar Quarter for each such DT Co-Co Product (if any).

3. Financial Records.

Each Party shall keep all financial records and reports required by this Schedule J (Co-Co Products Profit and Loss Share) in accordance with the U.S. GAAP principles to the extent applicable hereunder.

4. Operating Profits or Loss Sharing.

4.1 The Parties agree to share the Operating Profits or Losses with respect to Commercialization activities, Medical Affairs activities, and the activities related to Other Operating Expenses for each DT Co-Co Product (whether such Commercialization activities, Medical Affairs activities, and the activities related to Other Operating Expenses were conducted before or after Regulatory Approval for each DT Co-Co Product) as set forth in Section 7.4 (Co-Co Products Profit and Loss Share) of this Agreement.

4.2 Each Party is entitled to [***] of the Operating Profits or Losses for a given Calendar Quarter. If, taking into account the Net Sales, Cost of Sales, Licensing Income received, and Eligible Medical Affairs Costs, Commercialization Costs, and Other Operating Expenses incurred by the Parties as outlined in the P&L for such DT Co-Co Product, in each case, in such Calendar Quarter, an amount is due from one Party to the other to effect the Profit and Loss Share, then at the time the applicable Consolidated Report is delivered to Moderna, Metagenomi shall make a payment to Moderna for an amount such that Metagenomi shall be bearing [***] of the Operating Profits or Losses for the applicable Calendar Quarter. Metagenomi shall make payment in full to Moderna [***] after the date of an invoice therefor from Moderna. Likewise, if with respect to such Calendar Quarter, a balancing payment is due from Moderna to Metagenomi to effect the Profit and Loss Share, then, [***] after the applicable Consolidated Report is delivered to Metagenomi, Moderna shall pay Metagenomi an amount such that Metagenomi shall receive [***] of the Operating Profits or Losses for the applicable Calendar Quarter.

4.3 Disputes

In the event any invoiced payment that is not otherwise subject to a good faith dispute is made after the date specified in Paragraph 4.2 of this Schedule J (Co-Co Products Profit and Loss Share), the paying Party shall pay the additional amounts or the receiving Party shall reimburse such excess payments, as applicable, with interest from the date originally due as provided in Section 7.15 (Default Interest) of this Agreement, and the remaining, disputed portion of any such payment shall be paid within [***] after the date on which the JSC, using good faith efforts, resolves the dispute, or as escalated in accordance with Section 2.10 (Decisions) with respect to the DT Co-Co Product.

Schedule J-3

5. Start of Operations and Effective Accounting Date Termination.

5.1 The Profit and Loss Share shall commence on the Effective Date. For clarity, Cost of Sales, Eligible Medical Affairs Costs, Commercialization Costs, and Other Operating Expenses incurred prior to Regulatory Approval of each DT Co-Co Product are chargeable to the applicable Profit and Loss Share in accordance with U.S. GAAP principles.

5.2 The Profit and Loss Share shall continue until this Agreement is terminated or expires.

6. Audits.

The record keeping and audit provisions set forth in Section 7.6 (Accounting; Audit) of this Agreement shall apply with respect to all amounts payable by either Party to the other Party under the Profit and Loss Share, including with respect to the calculation of Eligible Medical Affairs Costs, Commercialization Costs, Other Operating Expenses, Licensing Income, Cost of Sales and Net Sales with respect to the performance of Commercialization activities, Medical Affairs activities and the activities under Other Operating Expenses for each DT Co-Co Product in the Territory.

Partnership Tax Matters

1.1. Constructive Partnership, Tax Treatment.

1.1.1. Metagenomi and Moderna (the “Partners,” and each a “Partner”) acknowledge that the rights and obligations imposed on each of them pursuant to this Agreement that relate to the allocation of Profits and Loss Share pursuant to Article 7 (Fees, Royalties, & Payments), any other sharing of profits and losses from the Commercialization of the Products within the Field in the Territory, and the collaborative relationship formed between them in connection therewith, in each case solely in connection with the DT Co-Co Program, gives rise to a partnership for U.S. federal (and, to the extent applicable, state and local) income tax purposes (the “Partnership”), which will commence upon DC Nomination in such DT Co-Co Program (the “Partnership Commencement Date”). The activities of the Partners on or after the Partnership Commencement Date with respect to the Commercialization of the Product within the Field in the Territory and the rights related thereto in the DT Co-Co Program (the “Shared Rights”) shall be deemed to be conducted in and held by the Partnership. The Partnership shall not, and shall not be deemed to, have any interest or rights relating to Product outside the Field or outside the Territory (with respect to the DT Co-Co Program) or otherwise under this Agreement other than with respect to the Shared Rights. The Partnership, and the rights and obligations set forth in this Schedule M, shall remain in existence for so long as this Agreement remains in full force and effect (provided this Agreement has not been terminated in its entirety, in accordance with Article 12 of this Agreement or otherwise) or until the DT Co-Co Program is terminated pursuant to Section 1.8 of this Schedule M, if such termination occurs prior to the termination of the Agreement in its entirety. Prior to the commencement of the Partnership, the Parties may mutually and in good faith determine that it is desirable to affect the arrangement between Metagenomi and Moderna with respect to the DT Co-Co Program as two or more Partnerships for U.S. federal income tax purposes, rather than as a single Partnership, each between Metagenomi or a Metagenomi Affiliate, as one partner, and Moderna or a Moderna Affiliate, as the second partner; provided, however, that, unless otherwise mutually agreed to by Metagenomi and Moderna, an Affiliate that is a foreign person for U.S. federal income tax purposes may only be a partner in any Partnership if the use of such foreign Affiliate shall not adversely impact the second partner. Metagenomi and Moderna shall cooperate in a reasonably prompt manner in order to effect any amendments to this Schedule M or this Agreement required or advisable as a result of the preceding sentence. The Parties further acknowledge that the arrangement described in this Agreement (including this Schedule M) shall be treated by the Parties as a partnership solely for U.S. federal and applicable state and local income tax purposes and is not intended to constitute a partnership for any non-tax, non-U.S., or any other purpose. The Partners agree not to take any tax position, whether in a tax return or otherwise, that is inconsistent with this Schedule M, other than pursuant to Section 1.7 of this Schedule M.

1.1.2. For U.S. federal income and other applicable tax purposes, on the Partnership Commencement Date Metagenomi shall be treated as contributing to the Partnership its undivided interest in the Metagenomi Licensed DT Co-Co Technology and its portion of the Commercialization rights with respect to the DT Co-Co Product in the Territory (with respect to the DT Co-Co Program) under this Agreement, and Moderna shall be treated as contributing to the Partnership its undivided interest in the Moderna Licensed DT Co-Co Technology and its portion of the Commercialization rights with respect to the DT Co-Co Product in the Territory (with respect to the DT Co-Co Program) under this Agreement, each as a Capital Contribution in exchange for an interest in the Partnership.

Schedule M-1

(a) shall be increased by (A) the Capital Contributions by such Partner to the Partnership after the Partnership Commencement Date, as determined by the Partnership Representative and mutually agreed upon by the Partners (net of liabilities secured by the contributed property that the Partnership is considered to assume or take subject to under Section 752 of the Code), and (B) such Partner’s distributive share of Net Income and other items of income and gain allocated to such Partner after the Partnership Commencement Date;

(b) shall be decreased by (A) the amount of money distributed (or deemed distributed) to such Partner by the Partnership after the Partnership Commencement Date, (B) the fair market value of property (as determined by the Partnership Representative and mutually agreed upon by the Partners) distributed (or deemed distributed) to such Partner by the Partnership (net of liabilities secured by the distributed property that the Partner is considered to assume or take subject to under Section 752 of the Code) after the Partnership Commencement Date and (C) such Partner’s distributive share of Net Losses and other items of loss and deduction allocated to such Partner after the Partnership Commencement Date; and

(c) other adjustments shall be made to the Capital Accounts of the Partners to accord with the regulations promulgated under Section 704(b) of the Code as determined by the Partnership Representative and mutually agreed upon by the Partners.

1.3.3. As of the Partnership Commencement Date, the initial Capital Account of each Partner shall be equal to the Capital Contribution of each such Partner pursuant to Section 1.1.2 of this Schedule M.

1.4. Distributions.

1.4.1. Non-Liquidating Distributions. In the event that assets of the Partnership are deemed to be distributed other than in liquidation of the Partnership, such assets shall be deemed to be distributed in accordance with the payments comprising the share of Operating Profit or Losses between Metagenomi and Moderna under Section 7.4 (Co-Co Products Profit and Loss Share) of this Agreement (the “Profit Share”), unless otherwise determined by the Partnership Representative and mutually agreed upon by the Partners.

Schedule M-3

1.4.2. Liquidating Distribution. In the event that the Partnership is terminated pursuant to Section 1.8 of this Schedule M, then the assets of the Partnership shall be distributed (or deemed to be distributed) in liquidation of the Partnership in accordance with the Profit Share, and the requirements under Section 5.6 of this Agreement shall be deemed to occur after such distribution and in exchange for payments required pursuant to Section 7.11 of this Agreement, as applicable.

1.4.3. Withholding for Taxes. Subject to the provisions of Section 7.16.3 of this Agreement, any Partner is authorized to withhold from payments made to the other Partner that are treated as distributions described in Section 1.4.1 or Section 1.4.2 of this Schedule M to the Partners, and with respect to allocations pursuant to Section 1.5 of this Schedule M to the Partners, and to pay over to any federal, state or local government, any such taxes as are required to be deducted or withheld under any provision of Applicable Law. Any amounts so withheld shall be treated as distributed pursuant to Section 1.4.1 or Section 1.4.2 of this Schedule M, as applicable.

1.5. Allocations, Section 704(c).

1.5.1. Except as required by Section 1.5.2 or Section 1.5.3 of this Schedule M, the Net Income or Net Loss for any Taxable Year shall be allocated to the Partners in such a manner so that the Capital Account of each Partner equals (as of the end of such allocation period and to the fullest extent possible) the amount that would be distributed to such Partner if all properties of the Partnership, including cash, were sold for cash equal to their respective Gross Asset Values, all liabilities allocable to such properties were then due and were satisfied according to their terms, all minimum gain chargebacks required by this Agreement and the Treasury Regulations were made, all obligations of Partners to contribute additional capital to the Partnership were satisfied and all remaining proceeds from such sale were distributed pursuant to the order and priority of Section 1.4.2 of this Schedule M.

1.5.2. Special Allocations. Notwithstanding Section 1.5.1 of this Schedule M, the Partnership Representative may, if mutually agreed upon by the Partners, specially allocate any costs or expenses that are disproportionately borne by one Partner to such Partner.

1.5.3. Regulatory Allocations. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6) of the Treasury Regulations, items of income (including gross income) and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate the deficit balance in such Partner’s Capital Account (in excess of (i) the amount such Partner is obligated to restore upon liquidation of the Partnership or upon liquidation of such Partner’s interest in the Partnership and (ii) such Partner’s share of the Minimum Gain (as defined in Section 1.704-2 of the Treasury Regulations)) created by such adjustments, allocations or distributions as quickly as possible. Additionally, there are hereby incorporated herein such special allocation provisions governing the allocation of income, deduction, gain, and loss for U.S. federal income tax purposes as may be necessary under, and in the manner required by, the Treasury Regulations to ensure that this Schedule M complies with all requirements of Section 1.704-2 of the Treasury Regulations relating to “minimum gain” and “partner nonrecourse debt minimum gain” and the allocation and chargeback of so-called “nonrecourse deductions” and “partner nonrecourse deductions”, including a “qualified income offset”.

Schedule M-4

1.5.4. Except as otherwise provided in this Section 1.5.4 and in Section 1.5.5 of this Schedule M, for U.S. federal income tax purposes, all items of income gain, loss, deduction and credit shall be allocated among the Partners in the same manner the corresponding Book item was allocated pursuant to Section 1.5.1 or Section 1.5.2 of this Schedule M. In the case of contributed property, items of income, gain, loss, deduction and credit, as determined for U.S. federal income tax purposes, shall be allocated first in a manner consistent with the requirements of Section 704(c) of the Code to take into account the difference between the Gross Asset Value of such property and its adjusted tax basis at the time of contribution. If the Gross Asset Value of any asset of the Partnership is adjusted pursuant to the terms of this Schedule M, then subsequent allocations of income, gain, loss, deduction and credit, as determined for U.S. federal income tax purposes, shall be allocated with respect to such assets so as to take into account such adjustment in the same manner as under Section 704(c) of the Code and the Treasury Regulations promulgated thereunder.

1.5.5. Metagenomi and Moderna shall mutually and in good faith agree on the method under Section 704(c) of the Code and the Treasury Regulations to be utilized by the Partnership prior to the Partnership Commencement Date. For the sake of clarity, the allocations required by Section 1.5.4 and this Section 1.5.5 of this Schedule M are solely for purposes of U.S. federal and applicable state and local income taxes and will not affect the allocation of Net Income or Net Losses as between the Partners or any Partner’s Capital Account.

1.6. Tax Reports, Tax Elections and Partnership Representative.

1.6.1. To the extent permitted under Applicable Law, the Partnership intends to elect out of the application of Subchapter C of Chapter 63 of the Code (i.e., the partnership audit rules) and any applicable state or local equivalent. For any applicable Taxable Year (or portion thereof) where the Partnership is able to so elect, the Partners agree to cooperate to share information relevant to the matters addressed by this Schedule M and agree not to take any position on any tax return applicable to the matters addressed by this Schedule M that may be materially adverse to the other Partner without the consent of the other Partner, not to be unreasonably withheld, delayed or conditioned. To the extent required after giving effect to the first sentence of Section 1.6 of this Schedule M, the Partnership hereby designates Moderna to act as the “partnership representative” of the Partnership within the meaning of Section 6223 of the Code (along with any state or local equivalent, the “Partnership Representative”), and the Partnership Representative shall have the authority to appoint the “designated individual” within the meaning of Treasury Regulations Section 301.6223-1(b)(3). If the Partnership is unable to elect out of the partnership audit rules, the Partnership Representative is authorized and required to represent the Partnership in connection with all examinations of the Partnership’s affairs by U.S. federal (and any applicable state) income tax authorities, including resulting administrative and judicial proceedings, to make any elections in connection therewith that are mutually agreed upon by the Partners, and to incur expenses for professional services and costs associated therewith, which shall be equally borne by each of Metagenomi and Moderna; provided, that the Partnership Representative shall notify Metagenomi of any such administrative and judicial proceedings involving the Partnership and shall provide Metagenomi the opportunity to jointly participate in any such matters. Metagenomi agrees to cooperate with the Partnership Representative as reasonably requested by the Partnership Representative with respect to the conduct of such proceedings. The Partnership Representative will, with mutual agreement by the Partners,

Schedule M-5

determine whether the Partnership (either on its own behalf or on behalf of the Partners) will contest or continue to contest any tax deficiencies assessed or proposed to be assessed by any taxing authority provided, however, that the Partnership Representative shall not (i) agree or consent to compromise or settle such matters or (ii) take any action that disproportionately adversely affects Metagenomi, without the mutual agreement of the Partners. Any deficiency for taxes imposed on any Partner (including penalties, additions to tax or interest imposed with respect to such taxes) will be paid by such Partner, and if paid by another Partner, will be recoverable from the Partner on which such deficiency was imposed (including by offset against distributions otherwise payable to such Partner). The Partners agree to cooperate in good faith to notify each other regarding any tax notices or audits relating to the Partnership and to provide any information or documentation reasonably requested by the Partnership Representative in connection with its duties under this Section 1.6.1 of this Schedule M. In no event shall the Partnership Representative require the Partners to file an amended tax return. A Partner’s obligation to cooperate with the Partnership Representative and to indemnify and make payments to another Partner under this Section 1.6.1 of this Schedule M will survive the termination, dissolution, liquidation and winding up of the Partnership and the transfer, assignment or liquidation of a Partner’s interest in the Partnership.

1.6.2. The Partnership Representative shall prepare and file, or cause to be prepared and filed, all necessary U.S. federal, state or local income tax returns for the Partnership. The Partnership Representative shall have such tax returns prepared by a “big four” accounting firm, which initially shall be Ernst & Young, such accounting firm to be chosen with Metagenomi’s consent, and the cost of the preparation of such tax returns shall be equally borne by each of Metagenomi and Moderna. At least 60 days before the due date (including extensions) of any such tax return, the Partnership Representative shall submit a copy of such tax return to Metagenomi for its review and comment. The Partners shall mutually agree on the preparation of such tax returns, making any required changes no fewer than 10 days prior to the due date of such tax return. Within 180 days after the end of each Taxable Year, the Partnership Representative shall cause the Partnership to furnish Metagenomi with an IRS Form K-1 for such Taxable Year. In addition, the Partnership shall deliver or cause to be delivered not later than the 15th day after the end of each Taxable Year to a requesting Partner all information necessary for the preparation of such Partner’s U.S. federal income tax returns and any state, local and other income tax returns that such Partner is required to file. Furthermore, the Partnership Representative shall jointly determine with Metagenomi regarding any matter for which the Partnership Representative is responsible or over which the Partnership Representative has discretion under this Schedule M, including without limitation the preparation of any tax return or the making of any election hereunder.

1.6.3. The Partners shall jointly determine whether to make or revoke any available election pursuant to the Code. Each Partner will, upon request, use reasonable efforts to supply the information necessary to give proper effect to any such election. The Partners hereby agree to cooperate in good faith regarding any matters related to any tax elections or tax reporting positions of the Partnership.

Schedule M-6

1.7. Tax Position. Unless otherwise required by Applicable Law, no Partner will take a position on such Partner’s U.S. federal or other applicable income tax returns, in any claim for refund or in any administrative or legal proceedings that is inconsistent with this Agreement (including this Schedule M) or with any information return filed by the Partnership. If any Partner believes that such a position is required by Applicable Law, such Partner must immediately notify the other Partner in writing, citing such Applicable Law or any interpretation thereof.

1.8. Termination of Partnership. With respect to the DT Co-Co Program, the Partnership shall terminate upon the earlier of (i) the expiration or termination of the DT Co-Co Program, or (ii) an Opt-Out by either Party from the DT Co-Co Program.
