Article 2

Collaboration

2.1.	Selection of Collaboration Targets.

2.1.1.

Wave 1 Targets.

(a)

Initial Wave 1 Target. The first Collaboration Target will be [***], as set forth on Schedule 2.1.1(a) ([***]) (“[***]”).

(b)

Second Wave 1 Target. Within [***] of the Effective Date, the Parties will mutually agree on the second gene target as a Collaboration Target (the “Second Wave 1 Target”). The Second Wave 1 Target will be a target for which a Licensed Product would be delivered only to [***]. If the Parties do not agree on a Second Wave 1 Target within such [***] period, then the Parties will mutually agree on an additional period to determine a second gene target to be the Second Wave 1 Target.

(c)

Additional Wave 1 Target Selection. At any time during the period commencing on the Effective Date and ending on the date that is [***] following the Effective Date (“Additional Wave 1 Target Selection Period”), Ionis may, in its sole discretion, but subject to Section 2.1.4 (Encumbrance Check), select up to two additional gene targets as proposed Collaboration Targets by providing written notice to Metagenomi (each such notice, the “Additional Wave 1 Target Notice”), which notice will identify the proposed target (“Additional Wave 1 Target”). The Additional Wave 1 Targets will be targets for which a Licensed Product would be delivered only to [***] or only to [***]; provided that [***].

2.1.2.

If, at any time during the Drug Discovery Term, (a) [***] or (b) the Parties achieve [***] under the Exploratory Research Activities (the “Wave 2 Target Selection Period”), then Ionis may, in its sole discretion, but subject to Section 2.1.4 (Encumbrance Check), select up to four additional gene targets as proposed Collaboration Targets by providing written notice to Metagenomi (each such notice, a “Wave 2 Target Notice”), which notice will identify the proposed target (“Wave 2 Target”). Each Wave 2 Target will be a target for which a Licensed Product would be delivered only to [***] or only to [***], or [***] that has, at the time of the Wave 2 Target Notice for such Wave 2 Target [***].

2.1.3.

Target Substitutions. On a Drug Discovery Program-by-Drug Discovery Program basis, Ionis will have the right to substitute the Collaboration Target for a Drug Discovery Program in accordance with this Section 2.1.3 (Target Substitutions).

(a)

Discretionary Substitutions. At any time before [***] (the “Target Substitution Period”), Ionis may, in its sole discretion, but subject to Section 2.1.4 (Encumbrance Check), replace the Collaboration Target for such Drug Discovery Program by providing written notice to Metagenomi, which notice will identify the proposed replacement gene target. Ionis may substitute (i) up to [***] and (ii) up to [***], in each case ((i) and (ii)), for any reason. Any Collaboration Target that is substituted out pursuant to this Section 2.1.3(a) (Discretionary Substitutions) will [***].

(b)

Substitutions for Technological Infeasibility. If the JSC determines that it is technologically infeasible to Develop a Development Candidate for a Collaboration Target (“Technological Infeasibility”), then Ionis may, in its sole discretion, but subject to Section 2.1.4 (Encumbrance Check), substitute such Collaboration Target by providing written notice to Metagenomi, which notice will identify the proposed replacement gene target. [***] and any substitutions that are for Technological Infeasibility will [***]. Any Collaboration Target that is substituted out pursuant to this Section 2.1.3(b) (Substitutions for Technological Infeasibility) will [***].

(c)

Substitution After Resolution of Technological Infeasibility. If a Collaboration Target is substituted out for Technological Infeasibility pursuant to Section 2.1.3(b) (Substitutions for Technological Infeasibility) and, [***], then Metagenomi will notify Ionis, which notice will include [***]. Subject to clauses (i) and (ii) of Section 2.1.4(a) (Encumbered Targets), Ionis will have the right to substitute a current Collaboration Target for such previous Collaboration Target by providing written notice to Metagenomi within [***] of receipt of notice from Metagenomi that [***]. [***] and any substitutions that are as a result of resolution of a Technological Infeasibility will [***].

(d)

Substitution Procedure. Any written notice provided by Ionis to Metagenomi pursuant to Section 2.1.3(a) (Discretionary Substitutions), Section 2.1.3(b) (Substitutions for Technological Infeasibility), or Section 2.1.3(c) (Substitutions After Resolution of Technological Infeasibility) will be a “Replacement Target Notice” and the proposed replacement gene target identified in any Replacement Target Notice will be a “Proposed Replacement Target”. Each Replacement Target Notice will specify which current Collaboration Target should be removed as a result of such replacement, and, unless otherwise agreed by the Parties, each Proposed Replacement Target will [***]. Promptly after such Proposed Replacement Target becomes a Collaboration Target pursuant to Section 2.1.4(c) (Effects if a Proposed Target is Available), Metagenomi will [***] after such Proposed Replacement Target becomes a Collaboration Target pursuant to Section 2.1.4(c) (Effects if a Proposed Target is Available).

2.1.4.

Encumbrance Check.

(a)

Encumbered Targets. Metagenomi will notify Ionis within [***] after Metagenomi’s receipt of an Additional Wave 1 Target Notice, a Wave 2 Target Notice, or a Replacement Target Notice if, at the time of receipt of such notice, (i) Metagenomi is [***], (ii) Metagenomi is [***], or (iii) the Proposed Target is [***], pursuant to which Metagenomi has [***] (each of (i) through (iii), a “Pre-Existing Restriction” and such Proposed Target, an “Encumbered Target”). Notwithstanding the foregoing, a Collaboration Target that has been substituted out for Technological Infeasibility but for which Ionis later selects as a Proposed Replacement Target pursuant to Section 2.1.3(c) (Substitutions After Resolution of Technological Infeasibility) will only be an Encumbered Target if the foregoing clause (i) or clause (ii) applies with respect to such Proposed Replacement Target. If Metagenomi does not notify Ionis within such [***] period that the [***]. If Metagenomi (x) notifies Ionis that a Proposed Target is Available or (y) does not provide notice that a Proposed Target is an Encumbered Target within the [***], then, in either case ((x) or (y)), such Proposed Target will be deemed to be Available, at which point Section 2.1.4(c) (Effects if a Proposed Target is Available) will apply. If a Proposed Target is an Encumbered Target, then Ionis may select another Proposed Target (and another if such other Proposed Target is an Encumbered Target and so on) until such time that Ionis selects a Proposed Target that is Available, at which point Section 2.1.4(c) (Effects if a Proposed Target is Available) will apply.

(b)

Expiration of Pre-Existing Restrictions. On [***], Ionis will [***], to facilitate its activities pursuant to Section 4.1.5(b) (Specific Responsibilities of the JSC), [***]. If at any time during the Additional Wave 1 Target Selection Period, the Wave 2 Target Selection Period, or the Target Substitution Period, as applicable, any Pre-Existing Restriction that precluded Ionis from selecting a Proposed Target as a Collaboration Target later expires, terminates, or is otherwise modified such that such Proposed Target would no longer be an Encumbered Target, and at such time (i) Ionis has not [***] as permitted under this Agreement, or (ii) Ionis has designated all Collaboration Targets as permitted under this Agreement, but Ionis has not exhausted its right to substitute existing Collaboration Targets as permitted under Section 2.1.3(a) (Discretionary Substitutions), Section 2.1.3(b) (Substitutions for Technological Infeasibility), or Section 2.1.3(c) (Substitution After Resolution of Technological Infeasibility) (such time period prior to the occurrence of both (i) and (ii), the “Target Selection and Substitution Period”), then Metagenomi will notify Ionis of such expiration, termination, or modification unless Ionis has notified the JSC that it is no longer interested in pursuing that Encumbered Target as a Collaboration Target.

(c)

Effects if a Proposed Target is Available. If Ionis confirms in writing to Metagenomi that a Proposed Target should be deemed to be a “Collaboration Target” under this Agreement within [***] of a Proposed Target being deemed Available pursuant to Section 2.1.4(a) (Encumbered Targets), then (i) such Proposed Target will be deemed a “Collaboration Target” as of the date of such notice, (ii) the Parties, through the JRC, will develop a Drug Discovery Plan for such Collaboration Target in accordance with Section 2.2.2 (Additional Drug Discovery Plans), (iii) if the Proposed Target was [***] in accordance with Section 9.2 ([***]) and, if applicable, the Drug Discovery Term will be extended pursuant to Section 2.2.7 (Drug Discovery Term), and (iv) if the Proposed Target was a Proposed Replacement Target, then the Collaboration Target that was substituted out will no longer be a “Collaboration Target”. If Ionis does not respond within [***] of a Proposed Target being deemed Available pursuant to Section 2.1.4(a) (Encumbered Targets), then such Proposed Target will not be deemed a “Collaboration Target”.

For clarity, Ionis will not be required to generate any additional data or information that is not in existence as of the date of Metagenomi’s request for an Option Package.

5.1.3.

Option Exercise. If Metagenomi decides to exercise the Co-Co Option for a particular Drug Discovery Program, then it will deliver written notice to Ionis of such determination during the applicable Co-Co Option Period, which notice will indicate the Drug Discovery Program for which Metagenomi elects to exercise the Co-Co Option, and (a) the Drug Discovery Program for which Metagenomi is exercising its Co-Co Option will automatically be deemed a “Co-Co Program” and all Licensed Products under such Drug Discovery Program will automatically be deemed “Co-Co Products,” (b) Metagenomi will pay Ionis the Option Exercise Fee for such Co-Co Program pursuant to Section 9.3 (Option Exercise Fee), and (c) the Parties will enter into a Co-Development and Co- Commercialization Agreement for such Co-Co Program in accordance with Section 5.2 (Development and Commercialization of the Co-Co Products; Opt-Down Right). Any Drug Discovery Program for which Metagenomi does not exercise a Co-Co Option prior to the expiration of the applicable Co-Co Option Period will automatically be deemed an “Ionis Program” and all Licensed Products under such Drug Discovery Program will automatically be deemed “Ionis Products” and Ionis will have sole control under the Development and Commercialization of such Ionis Products in accordance with Article 6 (Development and Commercialization of the Ionis Products).

5.2.

Development and Commercialization of the Co-Co Products; Opt-Down Right. On a Co-Co Program-by-Co-Co Program basis, promptly after Metagenomi exercises a Co-Co Option for a Co- Co Program, the Parties will negotiate in good faith the terms of a worldwide, co-exclusive (with Ionis) co-Development and co-Commercialization agreement (the “Co-Development and Co- Commercialization Agreement”), which terms and conditions will be reasonable and customary for agreements of this type and will include a requirement that the Parties share all future Development, Commercialization, and other Exploitation costs and all future profits with respect to the applicable Co-Co Products, with the Parties bearing the share of such costs [***] and Ionis being responsible for booking and recording revenue and on terms to be specified in the Co- Development and Co-Commercialization Agreement; provided, that [***]. Each Co-Development and Co-Commercialization Agreement will include: (i) the right for Metagenomi to, upon written notice to Ionis, reduce its share of any costs borne under the applicable Co-Co Program from [***]% to any percentage between [***]% and [***]% and Ionis’ share of such costs will increase accordingly (such option, the “Opt-Down Right”); provided that Metagenomi will continue to bear [***]% of the costs of [***], (ii) each Party will receive a share of profits equal to the percentage of costs funded by such Party following the exercise of the Opt-Down Right based on the percentage of costs that Metagenomi commits to funding in its notice of exercise of its Opt-Down Right, and (iii) Metagenomi may only exercise the Opt-Down Right during the period beginning no earlier than [***] and no later than [***] prior to the [***]. Until the Parties execute the Co-Development and Co-Commercialization Agreement, Ionis will continue to conduct and will be solely responsible for, and continue to have sole and exclusive control over, the Development and Manufacture of the applicable Co-Co Products.

5.3.

Escalation Procedure. If the Parties, despite their good faith negotiations, are unable to agree on the terms and conditions of any Co-Development and Co-Commercialization Agreement within [***] of the date of the applicable Co-Co Option Notice (or such longer time as mutually agreed by the Parties), then either Party may refer those terms and conditions to which they have not mutually agreed to the Executive Officers, who will use reasonable efforts to reach agreement on such terms and conditions. If such Executive Officers are unable to reach consensus with respect to such terms and conditions within [***] after such referral, then either Party may notify the other Party of its intent to invoke dispute resolution under Section 15.1.3 (Expedited Dispute Resolution).

5.4.

Metagenomi Opt-Out. On a Co-Co Program-by-Co-Co Program basis, Metagenomi will have the right to opt-out of its rights and obligations under this Agreement to the extent related to the Exploitation of the Co-Co Products under such Co-Co Program and the applicable Co- Development and Co-Commercialization Agreement for a Co-Co Program (each such right, an “Opt-Out Right”). Metagenomi may exercise the Opt-Out Right for a Co-Co Program by providing written notice to Ionis of such election no later than [***] after [***] (the “Opt-Out Period”). If Metagenomi exercises the Opt-Out Right for a Co-Co Program during the applicable Opt-Out Period pursuant to this Section 5.4 (Metagenomi Opt-Out), then from and after the date that is the later of (a) [***] or (b) [***] (the “Opt-Out Date”), (i) the applicable Co-Development and Co- Commercialization Agreement will terminate and Ionis will have sole control over, and sole decision-making authority with respect to, at its cost and expense, the Development, Commercialization, and other Exploitation of the Licensed Products under such Drug Discovery Program, (ii) the Licensed Products under such Drug Discovery Program will be deemed to be “Ionis Products” and such Drug Discovery Program will be deemed to be an “Ionis Program”, in each case, from and after the Opt-Out Date, (iii) [***], (iv) Ionis will [***], and (v) Metagenomi will [***].

Subject to Section 9.6.3 (Cumulative Effect of Ionis Royalty Reductions), Ionis will be entitled to credit against the Ionis Royalties due to Metagenomi in a given Calendar Quarter [***]% of (i) [***] that are actually paid by Ionis or any of its Affiliates or Sublicensees to any Third Party in consideration for rights under any Patent Right, Know-How, or other intellectual property owned or controlled by such Third Party (whether by acquisition or license) (such rights, “Third Party IP”) that is acquired or licensed by Ionis or any of its Affiliates or Sublicensees after the Effective Date, and [***] for Ionis or any of its Affiliates or Sublicensees to Exploit a Development Candidate as such Development Candidate exists as of the date of expiration of the Drug Discovery Term for the applicable Drug Discovery Program, and (ii) [***] (such amount in (i) or (ii), the “Third Party Payment”). Notwithstanding the foregoing, Third Party Payment shall exclude [***].

9.6.3.

Cumulative Effect of Ionis Royalty Reductions. In no event will the royalty reductions for Ionis Products permitted under Section 9.6.2(a) (Expiration of Valid Claims), Section 9.6.2(b) (Biosimilar Product), or Section 9.6.2(c) (Third Party Payments), alone or together, reduce the Ionis Royalties due to Metagenomi for an Ionis Product in a given Calendar Quarter by more than [***]% of the applicable Ionis Royalties that would otherwise be owed on the Annual Net Sales of such Ionis Product. If Ionis would, but for the restriction set forth in this Section 9.6.3 (Cumulative Effect of Ionis Royalty Reductions), have the right to reduce the Ionis Royalties due to Metagenomi by more than [***]%, then [***].

9.6.4.

Ionis Royalty Reports. Commencing on the First Commercial Sale of an Ionis Product and for so long as Ionis Royalties are due under this Agreement, no later than (a) [***] prior to the start of each Calendar Year, Ionis will deliver a written good faith non-binding estimate to Metagenomi of the projected Net Sales for the upcoming Calendar Year, (b) [***] after the end of each Calendar Quarter, Ionis will deliver a written good faith non- binding estimate to Metagenomi of the Net Sales in the relevant Calendar Quarter and the Ionis Royalties payable on such Net Sales, and (c) [***] after the end of each Calendar Quarter, Ionis will deliver a written report (each, an “Ionis Royalty Report”) to Metagenomi specifying on an Ionis Product-by-Ionis Product and country-by-country basis: (i) Net Sales in the relevant Calendar Quarter; (ii) to the extent such Net Sales include sales not denoted in US Dollars, a summary of the then-current exchange rate methodology(ies) used for the calculation of Net Sales in accordance with Section 9.14 (Currency of Payment; Non-Refundable Payments); (iii) the Ionis Royalties payable on such Net Sales; and (iv) if applicable, the Ionis Product Sales Milestone Payments owed to Metagenomi in the relevant Calendar Quarter. All Ionis Royalty Reports will be the Confidential Information of Ionis. Ionis will pay the Ionis Royalties for each Calendar Quarter no later than [***] after receipt of an invoice from Metagenomi, which invoice will be provided promptly following Metagenomi’s receipt of each Ionis Royalty Report from Ionis pursuant to this Section 9.6.4 (Ionis Royalty Reports). For clarity, the submission by Metagenomi of an invoice to Ionis based on an Ionis Royalty Report will be without prejudice to Metagenomi’s right to dispute an Ionis Royalty Report or to audit an Ionis Royalty Report pursuant to Section 9.13 (Records and Audits).

9.7.	Existing In-License Agreements.

9.7.1.

Effective Date Licensed Technology; Existing Metagenomi In-License Agreements. Metagenomi hereby represents and warrants that none of the Licensed Technology Controlled by Metagenomi as of the Effective Date is in-licensed or acquired by Metagenomi under agreements with Third Party licensors or sellers. On a Collaboration Target-by-Collaboration Target basis, if any Patent Rights or Know-How, as of the date a Proposed Target becoming a Collaboration Target pursuant to Section 2.1.4(c) (Effects if a Proposed Target is Available), have been acquired or in-licensed by Metagenomi and if solely owned by Metagenomi without any encumbrance or restriction on licensing, would constitute Licensed Technology as a result of such Proposed Target becoming a Collaboration Target pursuant to Section 2.1.4(c) (Effects if a Proposed Target is Available) (any such agreement, an “Existing Potential Metagenomi In-License Agreement”), then Metagenomi will, within [***] of the applicable Proposed Target becoming a Collaboration Target, provide Ionis with (a) notice and a copy of such Existing Potential Metagenomi In-License Agreements (which may be redacted to exclude provisions thereof that would not be applicable to Ionis as a licensee or sublicensee (as the case may be)), and (b) any disclosures that would be made against the representations and warranties in Section 12.2 (Additional Representations of Metagenomi) if such Existing Potential Metagenomi In-License Agreements were to become Metagenomi In-License Agreements. If Ionis provides written notice, within [***] of receipt of such information from Metagenomi, that it would like to have any such Existing Potential Metagenomi In- License Agreement included in the licenses granted under this Agreement and be subject to the terms of such Existing Potential Metagenomi In-License Agreement that are applicable to a licensee or sublicensee (as the case may be) thereunder, then such intellectual property rights described in such notice will automatically be deemed included in the Licensed Technology, and such Existing Potential Metagenomi In-License Agreement will be considered a Metagenomi In-License Agreement. Except as otherwise provided in this Agreement, as between the Parties, [***] will be responsible for all payments that arise under any license or other agreement to which Metagenomi or its Affiliate is a party, including any Metagenomi In-License Agreement, in connection with this Agreement, including with respect to the Development, Manufacture, and Commercialization of Licensed Products.

9.7.2.

Existing Potential Ionis In-License Agreements. With respect to any Patent Rights or Know-How that are the subject of an Ionis IP Option and are in-licensed or acquired by Ionis from any Third Party as of the applicable Ionis IP Option Effective Date (any such agreement, an “Existing Potential Ionis In-License Agreement”), Ionis will, within [***] of the applicable Ionis IP Option Effective Date, provide Metagenomi with notice and a copy of each such Existing Potential Ionis In-License Agreement (which may be redacted to exclude provisions thereof that would not be applicable to Metagenomi as a licensee or sublicensee (as the case may be)). If Metagenomi provides written notice, within [***] of receipt of such information from Ionis, that it would like to have any such Existing Potential Ionis In-License Agreement included in the licenses granted under this Agreement and be subject to the terms of such Existing Potential Ionis In-License Agreement that are applicable to a licensee or sublicensee (as the case may be) thereunder, then such intellectual property rights described in such notice will automatically be deemed included in the Ionis Background Technology and such Existing Potential Ionis In-License Agreement will be considered an Ionis In-License Agreement.

9.8.	New In-License Agreements.

9.8.1.

Proposed New In-License Agreements. Either Party (an “Acquiring Party”) may, during the Term, acquire or in-license rights to additional intellectual property from a Third Party that, if solely owned by such Party, without any encumbrance or restriction on licensing, would constitute Licensed Technology (if such Acquiring Party is Metagenomi) or Ionis Background Technology (if such Acquiring Party is Ionis) (any such agreement entered into by Metagenomi, a “Proposed New Metagenomi In-License Agreement,” any such agreement entered into by Ionis, a “Proposed New Ionis In-License Agreement,” and any Proposed New Metagenomi In-License Agreements or Proposed New Ionis In-License Agreements, a “Proposed New In-License Agreement”). Any such Proposed New In- License Agreement will be freely licensable or sublicensable to the non-Acquiring Party to the same extent that Licensed Technology or Ionis Background Technology (as applicable) is licensed to the non-Acquiring Party hereunder (including the right to grant sublicenses through multiple tiers) and will not (a) impose any material restrictions or obligations on the non-Acquiring Party as a licensee or sublicensee or (b) disadvantage the non-Acquiring Party, in each case ((a) and (b)), as compared to any other potential licensee or sublicensee under such Proposed New In-License Agreement. The Acquiring Party will [***] include in any such Proposed New In-License Agreement that is an in-license a provision pursuant to which [***]. Promptly following execution of a Proposed New In-License Agreement, the Acquiring Party will provide the non- Acquiring Party with a copy of such Proposed New In-License Agreement (which may be redacted to exclude provisions thereof that would not be applicable to the non-Acquiring Party as a licensee or sublicensee (as the case may be)).

9.8.2.

Acceptance of a Proposed In-License Agreement. If the non-Acquiring Party provides written notice, within [***] of receipt of a Proposed New In-License Agreement, that it would like to have such intellectual property rights included in the licenses granted under this Agreement and be subject to the terms of such Proposed New In-License Agreement that are applicable to a licensee or sublicensee (as the case may be) thereunder, then such intellectual property rights described in such notice will automatically be deemed included in the Licensed Technology (if such Acquiring Party is Metagenomi) or Ionis Background Technology (if such Acquiring Party is Ionis) (any such Proposed New Metagenomi In- License Agreement with respect to intellectual property rights that are included in the Licensed Technology pursuant to this sentence, a “New Metagenomi In-License Agreement,” any such Proposed New Ionis In-License Agreement with respect to intellectual property rights that are included in the Ionis Background Technology pursuant to this sentence, a “New Ionis In-License Agreement” and any New Metagenomi In- License Agreement or New Ionis In-License Agreement, a “New In-License Agreement”).

9.9.

Payment Obligations Under Certain In-License Agreements. Any payment obligations arising under the Metagenomi In-License Agreements or the Ionis In-License Agreements that are directly a result of the Development, Manufacture, or Commercialization of a Licensed Product or Metagenomi Product (as applicable) in the Field by or on behalf of the non-Acquiring Party or any of its Affiliates or Sublicensees, after application of all available reductions to and deductions from such payment obligations under the applicable agreement (but, for the avoidance of doubt, excluding [***]), will be paid by [***] and reimbursed by [***] in accordance with this Section 9.9 (Payment Obligations Under Certain In-License Agreements), but, with respect to [***], subject to [***] pursuant to Section 9.6.2(c) (Third Party Payments). Except as set forth in the immediately preceding sentence, [***] will be responsible for [***] under such agreements (including [***]). [***] will provide [***] with a reasonably detailed invoice for any payments made by [***] under a Metagenomi In-License Agreement or Ionis In-License Agreement that are reimbursable by [***] pursuant to this Section 9.9 (Payment Obligations Under Certain In-License Agreements) within [***], and [***] will pay the undisputed portion of such invoices within [***] of receipt thereof. For clarity, [***] and its Affiliates will be obligated to [***] a given amount owed under a Metagenomi In-License Agreement or Ionis In-License Agreement one time only. Notwithstanding the foregoing, [***] may, in its sole discretion, notify [***] that it elects to abandon its payment obligations under this Section 9.9 (Payment Obligations Under Certain In-License Agreements) with respect to a Metagenomi In-License Agreement or Ionis In-License Agreements, whereupon such agreement will no longer be deemed to be a Metagenomi In-License Agreement or Ionis In-License Agreements under this Agreement (as applicable) and [***] will no longer be responsible for such payment obligations from and after the date of such notice.

9.10.

Metagenomi Product Economics.

9.10.1.

Metagenomi Product Milestone Payments. If Metagenomi exercises the Ionis IP Option in accordance with Section 2.7 (Ionis Proprietary Toolbox of Chemical Modifications), then, on a Metagenomi Product-by-Metagenomi Product basis, Metagenomi will pay one- time milestone payments to Ionis of the amounts set forth in Table 9.10.1 (each, a “Metagenomi Product Milestone Event”) upon the first achievement by Metagenomi or any of its Affiliates or Sublicensees of each of the milestone events set forth in Table 9.10.1 (each, a “Metagenomi Product Milestone Payment”) for a Metagenomi Product. Each Metagenomi Product Milestone Payment is payable only once for each Metagenomi Product, regardless of the number of times the corresponding Metagenomi Product Milestone Event is achieved for a Metagenomi Product. If Metagenomi or its Affiliates or Sublicensees achieve all of the Metagenomi Product Milestone Events for a Metagenomi Product, then the Metagenomi Product Milestone Payments payable by Metagenomi under this Section 9.10.1 (Metagenomi Product Milestone Payments) for such Metagenomi Product will not exceed $[***].

	Table 9.10.1 – Metagenomi Product Milestones
	Metagenomi Product Milestone Event	Metagenomi Product Milestone Payment

9.10.2.

Notice; Payment; Skipped Milestones. Metagenomi will provide Ionis with written notice upon the achievement of each Metagenomi Product Milestone Event within [***] after such achievement and will pay Ionis within [***] after receipt of an invoice from Ionis. Each Metagenomi Product Milestone Event is intended to be successive. If any Metagenomi Product Milestone Event does not occur with respect to a Metagenomi Product, then such skipped milestone event will be deemed to have been achieved upon the achievement of the next successive milestone event with respect to such Metagenomi Product; provided that the [***] Metagenomi Product Milestone Event shall not be deemed to have been achieved upon the achievement of the [***] Metagenomi Product Milestone Event. Payment for any such skipped milestone that is owed in accordance with the provisions of the foregoing sentence will be due concurrently with the payment for the next successive Metagenomi Product Milestone Event.

9.10.3.

Metagenomi Royalties.

(a)

Metagenomi Royalty Rates. Subject to the terms and conditions of this Agreement, including the provisions of Section 9.10.3(b) (Adjustments to Metagenomi Royalties), on a Metagenomi Product-by-Metagenomi Product and country-by-country basis, Metagenomi will pay Ionis an amount equal to [***]% of the Net Sales of the applicable Metagenomi Product in a country in the Territory by Metagenomi and its Affiliates and its Sublicensees until the expiration of the applicable Metagenomi Royalty Term for such Metagenomi Product in such country. The royalty payments made pursuant to this Section 9.10.3(a) (Metagenomi Royalty Rates), the “Metagenomi Royalties” and the rate set forth in this Section 9.10.3(a) (Metagenomi Royalty Rates), the “Metagenomi Royalty Rate.”

(b)

Adjustment to Metagenomi Royalties. On a Metagenomi Product-by- Metagenomi Product and country-by-country basis in the Territory, if during the Metagenomi Royalty Term for a Metagenomi Product in a given country there is no Valid Claim of a Patent Right within the Ionis Background Technology Covering such Metagenomi Product in such country, then commencing in the first Calendar Quarter after the date on which this Section 9.10.3(b) (Adjustments to Metagenomi Royalties) applies and for the remainder of the Royalty Term for such Metagenomi Product in such country, the Net Sales for such Metagenomi Product in such country will be reduced by [***]% for purposes of calculating the Metagenomi Royalties owed under Section 9.10.3(a) (Metagenomi Royalty Rates).

9.10.4.

Metagenomi Royalty Reports. Commencing on the First Commercial Sale (applied mutatis mutandis) of a Metagenomi Product and for so long as Metagenomi Royalties are due under this Agreement, no later than (a) [***] prior to the start of each Calendar Year, Metagenomi will deliver a written good faith non-binding estimate to Ionis of the projected Net Sales for the upcoming Calendar Year, (b) [***] after the end of each Calendar Quarter, Metagenomi will deliver a written good faith non-binding estimate to Ionis of the Net Sales in the relevant Calendar Quarter and the Metagenomi Royalties payable on such Net Sales, and (c) [***] after the end of each Calendar Quarter, Metagenomi will deliver a written report (each, a “Metagenomi Royalty Report”) to Ionis specifying on a Metagenomi Product-by-Metagenomi Product and country-by-country basis: (i) Net Sales in the relevant Calendar Quarter; (ii) to the extent such Net Sales include sales not denoted in US Dollars, a summary of the then-current exchange rate methodology(ies) used for the calculation of Net Sales in accordance with Section 9.14 (Currency of Payment; Non- Refundable Payments); and (iii) the Metagenomi Royalties payable on such Net Sales. All Metagenomi Royalty Reports will be the Confidential Information of Metagenomi. Metagenomi will pay the Metagenomi Royalties for each Calendar Quarter no later than [***] after receipt of an invoice from Ionis, which invoice will be provided promptly following Ionis’ receipt of each Metagenomi Royalty Report from Metagenomi pursuant to this Section 9.10.4 (Metagenomi Royalty Reports). For clarity, the submission by Ionis of an invoice to Metagenomi based on a Metagenomi Royalty Report will be without prejudice to Ionis’ right to dispute a Metagenomi Royalty Report or to audit a Metagenomi Royalty Report pursuant to Section 9.13 (Records and Audits).

9.11.

Other Payments. With respect to any amounts owed under this Agreement by one Party to the other for which no other invoicing and payment procedure is otherwise specified in this Agreement, a Party will provide an invoice, together with reasonable supporting documentation, to the other Party for such amounts. The owing Party will pay any undisputed amounts within [***] of receipt of the invoice, and any disputed amounts owed by a Party will be paid within [***] of resolution of the dispute in accordance with Section 15.1 (Dispute Resolution).

9.13.

Records and Audits.

9.13.1.

Books and Records. Each Party will keep (and will cause its Affiliates and Sublicensees to keep) complete and accurate books and records pertaining to (a) in the case of Ionis, all Internal Costs and Out-of-Pocket Costs incurred in connection with the performance of the Drug Discovery Activities, Net Sales of Ionis Products, any amounts paid under any Ionis In-License Agreement, and any costs shared by the Parties for the Co-Co Products pursuant to a Co-Development and Co-Commercialization Agreement (the “Ionis Records”) and (b) in the case of Metagenomi, all Internal Costs and Out-of-Pocket Costs incurred in connection with the performance of the Collaboration Activities, Net Sales of the Metagenomi Products, any amounts paid under any Metagenomi In-License Agreement, and any costs shared by the Parties for the Co-Co Products pursuant to a Co-Development and Co-Commercialization Agreement (the “Metagenomi Records”), in each case ((a) and (b)), in reasonable detail to permit the other Party to confirm the accuracy of all payments or costs reported for at least the preceding [***]. During the Term and for a period of [***] thereafter, each Party (the “Auditing Party”) may, upon written request and subject to this Section 9.13 (Records and Audits), cause a nationally- recognized independent accounting firm (the “Auditor”), that is reasonably acceptable to the other Party (the “Audited Party”) to inspect the relevant records of such Audited Party and its Affiliates to verify the payments made and amounts reported by the Audited Party and the directly related reports, statements, and books of accounts, as applicable.

9.13.2.

Audit Procedure. Before beginning its audit, the Auditor will execute a written agreement acceptable to the Audited Party by which the Auditor agrees to keep confidential all information reviewed during the audit, which agreement will contain terms of non- disclosure and non-use no less stringent than those set forth in this Agreement, but otherwise will be reasonable and customary for the purposes of an audit of this nature. The Auditor will have the right to disclose to the Auditing Party only its conclusions regarding any payments owed under this Agreement. Each Party and its Affiliates will make their records available for inspection by the Auditor during regular business hours at such place or places where such records are customarily kept, upon receipt of reasonable advance notice from the Auditing Party. The records will be reviewed solely to verify the Audited Party’s compliance with the payment obligations and financial terms of this Agreement.

9.13.3.

Frequency; Overpayments and Underpayments. Such inspection right will not be exercised more than [***] and not more frequently than [***] with respect to records covering any specific period of time. In addition, the Auditing Party will only be entitled to audit the books and records of the Audited Party for the [***] prior to the [***] in which the audit request is made. The Auditing Party agrees to hold in strict confidence all information received and all information learned in the course of any audit or inspection, except to the extent necessary to enforce its rights under this Agreement or to the extent required to comply with any Applicable Law or judicial order. The Auditor will provide its audit report and basis for any determination to the Audited Party at the time such report is provided to the Auditing Party before it is considered final. If the final result of the inspection reveals an underpayment or overpayment by either Party, then the underpaid or overpaid amount will be settled promptly plus interest due on any underpayments in accordance with Section 9.15 (Late Fees). The Auditing Party will pay for such inspections, as well as its expenses associated with enforcing its rights with respect to any payments hereunder; unless such audit reveals an underpayment of amounts owed to, or an overpayment of amounts owed by, the Auditing Party of more than [***]% of the amount that was owed by the Audited Party or owed to the Audited Party, as applicable, with respect to the relevant period, in which case, the Audited Party will reimburse the Auditing Party for the reasonable expense incurred by the Auditing Party in connection with the audit.

9.14.

Currency of Payment; Non-Refundable Payments. All amounts to be paid pursuant to this Agreement will be made in United States Dollars and will be paid by wire transfer in immediately available funds to a bank account designated by the receiving Party. The rate of exchange to be used in computing the amount of currency equivalent in U.S. Dollars owed to a Party under this Agreement will be the paying Party’s then-current standard exchange rate methodology employed for the translation of foreign currency sales into U.S. Dollars in accordance with its Accounting Standards and consistently applied during the period. Any provisions of this Agreement that describe a payment as non-refundable will be without prejudice to either Party’s right to bring a claim for breach of this Agreement, misrepresentation, or any other claim permissible under Applicable Law, including seeking recovery of payments made and damages for loss.

9.15.

Late Fees. If a Party does not receive payment of any undisputed sum due to it on or before the due date set forth under this Agreement, then simple interest will thereafter accrue on the sum due to such Party from the due date until the date of payment at a per-annum rate of [***] or the maximum rate allowable under Applicable Law, whichever is lower.

9.16.

Currency Restrictions. If, by reason of Applicable Law in any country, it becomes impossible or illegal for a Party to transfer, or have transferred on its behalf, payments owed to the other Party hereunder, then such Party will promptly notify the other Party of the conditions preventing such transfer and such payments will be deposited in local currency in the relevant country to the credit of the other Party in a recognized banking institution designated by the other Party or, if none is designated by the other Party within a period of [***], in a recognized banking institution selected by the transferring Party, as the case may be, and identified in a written notice given to the other Party.

9.17.

Withholding Taxes. Either Party (a “Withholding Party”) may withhold from payments due to the other Party (a “Non-Withholding Party”) amounts for payment of any withholding tax that is required by Applicable Law to be paid to any taxing authority with respect to such payments, which will be remitted in accordance with Applicable Law. The Withholding Party will provide to the Non-Withholding Party all relevant documents and correspondence, and will also provide to the Non-Withholding Party any other cooperation or assistance on a reasonable basis as may be necessary to enable the Non-Withholding Party to claim exemption from such withholding taxes and to receive a refund of such withholding tax or claim a foreign tax credit. The Withholding Party will give proper evidence from time to time as to the payment of any such tax. The Parties will cooperate with each other in seeking deductions under any double taxation or other similar treaty or agreement from time to time in force. Such cooperation may include the Withholding Party making payments from a single source in the U.S., where possible. Notwithstanding the foregoing, [***].

Notification. Each Party will use reasonable efforts to promptly notify the other in the event of any actual, likely, or suspected infringement of any Ionis-Prosecuted Patent Right or Metagenomi-Prosecuted Patent Right (an “Infringement”), including any Infringement that arises as a result of the making, using, offering to sell, selling, or importing of a product that would be competitive with a Licensed System or Licensed Product (a “Competitive Infringement”).

10.3.2.

Competitive Infringements.

(a)

Ionis will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding to enforce the Ionis-Prosecuted Patent Rights against any Competitive Infringement at its own expense. If Ionis fails to initiate a Proceeding within a period of 90 days after written notice of a Competitive Infringement is first provided by a Party under Section 10.3.1 (Notification), then Metagenomi will have the right to initiate and control a Proceeding to enforce the applicable Patent Right against such Competitive Infringement by counsel of its own choice; provided that if Ionis notifies Metagenomi during such 90-day period that it is electing in good faith not to institute any Proceeding to enforce Ionis-Prosecuted Patent Rights against such Competitive Infringement for strategic reasons, then Metagenomi will not have the right to initiate and control any Proceeding to enforce such Patent Rights against such Competitive Infringement.

(b)

Metagenomi will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding to enforce the Metagenomi-Prosecuted Patent Rights against any Competitive Infringement at its own expense. If Metagenomi fails to initiate a Proceeding within a period of 90 days after written notice of a Competitive Infringement is first provided by a Party under Section 10.3.1 (Notification), then Ionis will have the right to initiate and control a Proceeding to enforce the applicable Patent Right against such Competitive Infringement by counsel of its own choice; provided that if Metagenomi notifies Ionis during such 90-day period that it is electing in good faith not to institute any Proceeding to enforce Metagenomi-Prosecuted Patent Rights against such Competitive Infringement for strategic reasons, then Ionis will not have the right to initiate and control any Proceeding to enforce such Patent Rights against such Competitive Infringement.

10.3.3.

Proceedings for Infringements other than Competitive Infringements. During the Term, (a) Metagenomi will have the sole right, but not the obligation, to initiate a Proceeding against any Infringement that is not a Competitive Infringement with respect to any Licensed Patent Rights, at Metagenomi’s sole discretion and at Metagenomi’s sole cost and expense and (b) the Parties will jointly agree upon any initiation of a Proceeding against any Infringement that is not a Competitive Infringement with respect to any Joint Collaboration Patent Right; provided that neither Party will unreasonably withhold its agreement to initiate any such Proceeding with respect to any Joint Collaboration Patent Right (as applicable) upon the reasonable request of the other Party.

10.3.4.

Collaboration. Each Party will provide to the enforcing Party reasonable assistance in any Proceeding brought under this Section 10.3 (Patent Enforcement), at such enforcing Party’s request and expense, including to be named in such action if required by Applicable Law to pursue such action. The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts, will reasonably consider the other Party’s comments on any such efforts, including determination of litigation strategy and filing of material papers to the competent court. The non-enforcing Party will be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party will at all times cooperate fully with the enforcing Party. The enforcing Party will not settle any Proceeding that it brought under Section 10.3.2 (Competitive Infringements) in any manner that would limit the rights of the other Party or impose any obligation on the other Party, without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned, or delayed.

10.3.5.

Expenses and Recoveries. Any amount recovered in any Proceeding under this Section 10.3 (Patent Enforcement), including any amount recovered in any settlement of such Proceeding, will first be used to [***] and will thereafter be for (a) with respect to any Competitive Infringement, the benefit of [***]; provided, however, that to the extent any such amount is [***], then such amount will, [***], and (b) with respect to any Infringement that is not a Competitive Infringement, for the benefit of [***].

10.4.

Defense of Claims Brought by Third Parties. If any Third Party brings a claim or otherwise asserts that a Licensed Product or Licensed System infringes such Third Party’s Patent Rights or misappropriates such Third Party’s Know-How (each, a “Third Party Infringement Claim”), then the Party first having notice of the claim or assertion will promptly notify the other Party in writing. Subject to [***], [***] will have the sole right, but not the obligation, to undertake and control the defense or settlement of any Third Party Infringement Claim using counsel of its choice, at its cost and expense. If [***] is named as a defendant in such suit, [***] will have the right to participate in such defense and settlement with its own counsel, at its cost. [***] will not enter into any settlement of any Third Party Infringement Claim that is instituted or threatened to be instituted against [***] without [***] prior written consent, which will not be unreasonably withheld, conditioned, or delayed; except that such consent will not be required if such settlement includes a release of all liability in favor of [***] or an assumption of any unreleased liability by [***]. As requested by [***], [***] will provide reasonable cooperation and assistance to [***] in connection with [***] control of the defense or settlement of a Third Party Infringement Claim. Such cooperation and assistance will include executing all necessary and proper documents and taking such actions as will be appropriate to allow [***] to control the defense and settlement of such Third Party Infringement Claim. [***] will [***]; except that [***] will have no obligation to [***]. [***] will keep [***] reasonably informed of the progress of any Third Party Infringement Claim. To the extent reasonable, both Parties will cooperate in good faith to (a) ensure that [***] and (b) [***].

10.5.

Patent Listing. Ionis will have the sole right, but not the obligation, to determine which Ionis- Prosecuted Patent Rights will be listed in connection with the Regulatory Approval for a Licensed Product pursuant to 21 U.S.C. § 355(b)(1)(G), any similar statutory or regulatory requirement enacted in the future regarding biologic products, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction. The Parties will discuss and mutually agree on which Metagenomi-Prosecuted Patent Rights will be listed in connection with the Regulatory Approval for a Licensed Product pursuant to 21 U.S.C. § 355(b)(1)(G), any similar statutory or regulatory requirement enacted in the future regarding biologic products, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction.

10.6.

Common Ownership Legislation. Notwithstanding anything to the contrary in this Article 10 (Intellectual Property), neither Party will have the right to make an election under the Common Ownership Legislation when exercising its rights under this Article 10 (Intellectual Property) without the prior written consent of the other Party, which will not be unreasonably withheld, conditioned, or delayed. With respect to any such permitted election, the Parties will use reasonable efforts to cooperate and coordinate their activities with respect to any submissions, filings, or other activities in support thereof. The Parties acknowledge and agree that this Agreement is a “joint research agreement” as defined in the Common Ownership Legislation. Notwithstanding the foregoing, the other Party’s consent under this Section 10.6 (Common Ownership Legislation) will not be required in connection with an obviousness-type double patenting rejection in any patent application claiming a Licensed System, Licensed Product, or uses thereof.

10.7.

Patent Term Extension.

10.7.1.

Ionis-Prosecuted Patent Rights. Ionis will be solely responsible for obtaining patent term restoration for the Ionis-Prosecuted Patent Rights in any country in the Territory under any statute or regulation equivalent or similar to 35 U.S.C. § 156, where applicable to a Licensed Product. Ionis will determine which relevant Ionis-Prosecuted Patent Rights will be extended (including by filing supplementary protection certificates and any other extensions that are now or in the future become available). Metagenomi will abide by Ionis’ determination and cooperate, as reasonably requested by Ionis, in connection with the foregoing (including by providing appropriate information and executing appropriate documents).

10.7.2.

Metagenomi-Prosecuted Patent Rights. The Parties will mutually agree on the strategy for obtaining patent term restoration for the Metagenomi-Prosecuted Patent Rights in any country in the Territory under any statute or regulation equivalent or similar to 35 U.S.C. § 156, where applicable to a Licensed Product. The Parties will mutually agree on which relevant Metagenomi-Prosecuted Patent Rights will be extended (including by filing supplementary protection certificates and any other extensions that are now or in the future become available) and will cooperate with each other in connection with the foregoing (including by providing appropriate information and executing appropriate documents).

10.8.

Recording. If Ionis deems it necessary or desirable to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate Governmental Authority in one or more jurisdictions in the Territory, then Metagenomi will reasonably cooperate to execute and deliver to Ionis any documents accurately reflecting or evidencing this Agreement that are necessary or desirable, in Ionis’ reasonable judgment, to complete such registration or recordation. Ionis will [***] in complying with the provisions of this Section 10.8 (Recording).

10.9.

Unitary Patent System. Ionis will have the exclusive right to opt-in or opt-out of the EU Unitary Patent System for all Licensed Patent Rights and Joint Collaboration Patent Rights. For clarity, “to opt-in or opt-out” refers to both the right to have a European patent application or an issued European patent registered to have unitary effect within the meaning of Regulation (EU) No 1257/2012 of December 17, 2012 as well as the Agreement on a Unified Patent Court as of February 19, 2013; and to the right to opt-in or opt-out from the exclusive competence of the Unified Patent Court in accordance with Article 83(3) of that Agreement on a Unified Patent Court. Without limiting the generality of the foregoing, unless a Party or its Affiliate has expressly opted-in to the EU Unitary Patent System with respect to a given Patent Right, the other Party will not initiate any action under the EU Unitary Patent System without such Party’s prior written approval, such approval to be granted or withheld in such Party’s sole discretion.

10.10.

Trademarks. As between the Parties, all trademarks and trade dress rights used in connection with the Commercialization of the Licensed Products in the Field in the Territory will be owned exclusively by Ionis.

10.11.

Common Interest. All information exchanged between the Parties regarding the Prosecution and Maintenance, and enforcement and defense, of the Patent Rights under this Article 10 (Intellectual Property) will be deemed Confidential Information of the disclosing Party. In addition, the Parties acknowledge and agree that, with regard to such Prosecution and Maintenance, and enforcement and defense of the Patent Rights under this Article 10 (Intellectual Property), the interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning the Patent Rights under this Article 10 (Intellectual Property), including privilege under the common interest doctrine and similar or related doctrines. Notwithstanding anything to the contrary contained herein, to the extent a Party has a good faith belief that any information required to be disclosed by such Party to the other Party under this Article 10 (Intellectual Property) is protected by attorney-client privilege or any other applicable legal privilege or immunity, such Party will not be required to disclose such information and the Parties will in good faith cooperate to agree upon a procedure (including entering into a specific common interest agreement, disclosing such information on a “for counsel eyes only” basis or similar procedure) under which such information may be disclosed without waiving or breaching such privilege or immunity.

Article 11

Confidentiality

11.1.

Confidential Information.

11.1.1.

General. Each Party will maintain all Confidential Information disclosed to it or its representatives (the “Receiving Party”) by or on behalf the other Party (the “Disclosing Party”) in strict confidence during the Term of this Agreement and for a period of [***] after the expiration or termination of this Agreement; provided that any Confidential Information of either Party that constitutes a trade secret will continue to be subject to the terms of this Article 11 (Confidentiality) in perpetuity, so long as such information remains a trade secret. Each Party will use all such disclosed Confidential Information only to the extent necessary for purposes of this Agreement, including exercising the licenses and rights hereunder, and will not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except as permitted under this Agreement. Each Party will notify the other Party promptly on discovery of any unauthorized use or disclosure by a Party of the other Party’s Confidential Information, including the other Party’s trade secrets.

11.1.2.

Confidential Information of Each Party. All information disclosed prior to the Effective Date pursuant to the Confidentiality Agreement between the Parties dated [***] (the “Confidentiality Agreement”), by Metagenomi to Ionis will be Confidential Information of Metagenomi and by Ionis to Metagenomi will be Confidential Information of Ionis. All Ionis Royalty Reports and reports identifying Ionis Product Development Milestone Events, Ionis Product Regulatory Milestone Events, and Ionis Product Sales Milestone Events will be considered Confidential Information of Ionis. All Metagenomi Royalty Reports and reports identifying Metagenomi Product Milestone Events will be the Confidential Information of Metagenomi. The Product-Specific Know-How, Joint Collaboration Know-How, and the non-disclosed terms of this Agreement will be the Confidential Information of each Party.

11.1.3.

Exceptions to Confidentiality. The following information will not be Confidential Information of the Disclosing Party, and accordingly the obligations of each Receiving Party imposed by Section 11.1.1 (General) will not apply to any such information that: (a) was known to the Receiving Party without an obligation to keep such information confidential prior to the Effective Date other than as a result of disclosure under any other agreement between the Parties, including the Confidentiality Agreement (as demonstrated by documentary evidence); (b) is or becomes generally available to the public through means other than an unauthorized disclosure by the Receiving Party, its Affiliates, or any agents to whom it or they disclosed such information; (c) was or subsequently is disclosed to the Receiving Party without restriction by a Third Party having a bona fide right to disclose such Confidential Information without breaching any obligation to the Disclosing Party; or (d) is developed independently by the Receiving Party without benefit of or recourse to any of the Disclosing Party’s Confidential Information (as demonstrated by documentary evidence). For clarity, (i) specific aspects or details of Confidential Information will not be deemed to be within the public domain or in the possession of the Receiving Party merely because the Confidential Information is embraced by more general information in the public domain or in the possession of the Receiving Party; and (ii) any combination of Confidential Information will not be considered in the public domain or in the possession of the Receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the Receiving Party unless the combination and its principles are in the public domain or in the possession of the Receiving Party.

11.1.4.

Permitted Disclosures. The Receiving Party may disclose Confidential Information of the Disclosing Party to the extent (and solely to the extent) that such disclosure is reasonably necessary in the following instances:

(a)

(i) the prosecution and maintenance of Licensed Patent Rights and Joint Collaboration Patent Rights, in each case, in accordance with the terms of this Agreement; or (ii) Regulatory Submissions and other filings with Governmental Authorities (including Regulatory Authorities), as necessary for the Exploitation of a Licensed Product;

(b)

disclosure of the existence and applicable terms of this Agreement and the status and results of Exploitation of one or more Licensed Products to actual or bona fide potential investors, acquirors, Sublicensees, lenders, and other financial or commercial partners (including in connection with any royalty factoring transaction), and their respective attorneys, accountants, banks, investors, and advisors, solely for the purpose of evaluating or carrying out an actual or potential investment, acquisition, sublicense, debt transaction, or collaboration; provided that, in each such case, (i) such Persons are bound by obligations of confidentiality, non-disclosure, and non-use provisions at least as restrictive or protective of the Parties as those set forth in this Agreement or otherwise customary for such type and scope of disclosure, and (ii) that any such disclosure is limited to the maximum extent practicable for the particular context in which it is being disclosed; provided that in no event will a disclosure of Confidential Information under this Section 11.1.4(b) be made, with respect to Ionis as the Receiving Party, to [***] or with respect to Metagenomi as the Receiving Party, to [***], in each case, without the prior written consent of the other Party;

(c)

to comply with Applicable Law (whether generally or in pursuit of an application for listing of securities) including the United States Securities and Exchange Commission or equivalent foreign agency or regulatory body, or otherwise required by judicial or administrative process; provided that in each such event, as promptly as reasonably practicable and to the extent not prohibited by Applicable Law or judicial or administrative process, such Party will notify the other Party of such required disclosure and provide a draft of the disclosure to the other Party reasonably in advance of such filing or disclosure for the other Party’s review and comment. The non-disclosing Party will provide any comments as soon as practicable, and the disclosing Party will consider in good faith any timely comments provided by the non-disclosing Party; provided that the disclosing Party may or may not accept such comments in its sole discretion. Confidential Information that is disclosed in order to comply with Applicable Law or by judicial or administrative process pursuant to this Section 11.1.4(c), in each case, will remain otherwise subject to the confidentiality and non-use provisions of this Article 11 (Confidentiality) with respect to the Party disclosing such Confidential Information, and such Party will take all steps reasonably necessary, including seeking of confidential treatment or a protective order for a period of at least [***] (to the extent permitted by Applicable Law or Governmental Authority), to ensure the continued confidential treatment of such Confidential Information, and each Party will be responsible for its own legal and other external costs in connection with any such filing or disclosure pursuant to this Section 11.1.4(c);

(d)

to prosecute or defend litigation so long as there is [***] prior written notice given by the Receiving Party before filing, and to enforce Patent Rights in connection with the Receiving Party’s rights and obligations pursuant to this Agreement; and

(e)

to allow the Receiving Party to exercise its rights and perform its obligations hereunder; provided that such disclosure is covered by terms of confidentiality and non-use at least as restrictive as those set forth herein.

If and whenever any Confidential Information is disclosed in accordance with this Section 11.1.4 (Permitted Disclosures), such disclosure will not cause any such information to cease to be Confidential Information except to the extent that such disclosure results in a public disclosure of such information (other than by breach of this Agreement).

11.2.

No Use of Name. Neither Party will use the other Party’s name, logo, or Trademarks in any promotional materials or advertising without the prior written consent of the other Party, except as provided under this Agreement or required by Applicable Law, in which case the Party disclosing such name, logo, or Trademarks will give advance notice of such use and otherwise comply with Section 11.1.4(c).

11.3.

Residual Knowledge. Notwithstanding any provision to the contrary set forth in this Agreement, a Receiving Party will not be liable for the use of any knowledge, technique, experience, or Know- How that is retained in the unaided memory of any officers, directors, agents, contractors, or employees of such Receiving Party after having access to such Confidential Information (“Residual Knowledge”), provided that such officer, director, agent, contractor, or employee (a) has not intentionally memorized such Residual Knowledge, (b) is not aware at the time of use that such Residual Knowledge is the Confidential Information of the Disclosing Party, and (c) has not been directed or encouraged by the Receiving Party to memorize such Residual Knowledge. Any use made by the Receiving Party of any such Residual Knowledge is on an “as is, where is” basis, with all faults and all representations and warranties disclaimed and at its sole risk. For clarity, no license under any Patent Right is granted pursuant to this Section 11.3 (Residual Knowledge).

11.4.

Public Announcements and Subsequent Disclosures. Except as may be expressly permitted under Section 11.1.4 (Permitted Disclosures), neither Party will make any public announcement regarding this Agreement without the prior written approval of the other Party, except for either Party’s references to the other as the licensor or licensee (as applicable) or a collaboration partner under this Agreement. For clarity, Ionis may make scientific publications or public announcements concerning Ionis’ Exploitation of any Licensed Product under this Agreement pursuant to Section 11.5.1 (Ionis Publications); provided that, except as permitted under Section 11.1.4 (Permitted Disclosures), Ionis will not disclose any of Metagenomi’s Confidential Information in any such publication or announcement without obtaining Metagenomi’s prior written consent to do so. The Parties may each issue, or, by agreement of the Parties, may jointly issue, a press release announcing the signing of this Agreement after the Effective Date. The press release(s) to be issued by the Parties on or after the Effective Date will be substantially in the form of the press release(s) attached hereto as Schedule 11.4 (Press Release(s)). After the issuance of any such press release or any other permitted public disclosure by a Party, each Party may make subsequent public disclosures reiterating such information without having to obtain the other Party’s prior consent and approval so long as the information in such press release or other public announcement remains true, correct, and the most current information with respect to the subject matters set forth therein.

11.5.

Publications.

11.5.1.

Ionis Publications.

(a)

During the Collaboration Term, Ionis will submit to Metagenomi for review any proposed academic, scientific, or medical publication or public presentation related to any Licensed System or Licensed Product or to any activities conducted pursuant to this Agreement. Metagenomi will review such publication or presentation for purposes of determining whether any portion of the proposed publication or presentation contains Metagenomi’s Confidential Information. Ionis will submit written copies of such proposed publication or presentation to Metagenomi no later than [***] before submission for publication or presentation (or [***] in advance in the case of an abstract). Metagenomi will provide its comments with respect to such publications and presentations within [***] after its receipt of such written copy (or [***] in the case of an abstract). Metagenomi will have the right: (i) to require the removal of its Confidential Information from any such publication or presentation and (ii) to request a reasonable delay in publication or presentation in order to protect patentable information. If Metagenomi requests such a delay, then Ionis will delay submission or presentation for a period of [***] after its provision of the copy of the proposed publication or disclosure to enable patent applications protecting Metagenomi’s rights in such information. Ionis will comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publication.

(b)

Unless otherwise agreed in a Co-Development and Co-Commercialization Agreement, after the Collaboration Term, Ionis will have the right upon at least [***] prior written notice to Metagenomi, without any required consent or review from Metagenomi but subject to this Article 11 (Confidentiality), to publish or publicly disclose the scientific results of any activities conducted with respect to any Licensed System or Licensed Product or any other activities conducted pursuant to this Agreement; provided that if Metagenomi reasonably believes that such disclosure would adversely affect the use of any Licensed System for applications outside of the Field, then Ionis will reasonably consider any comments to such disclosure provided by Metagenomi in such [***] period.

11.5.2.

Metagenomi Publications. During the Term, Metagenomi will not publish or publicly disclose the scientific results of any activities it conducts that are specific to the Licensed System or Licensed Product in the Field, or any other activities conducted pursuant to this Agreement and exclusively licensed to Ionis, in each case, without the prior written consent of Ionis (such consent not to be unreasonably withheld, conditioned, or delayed).

the negligence or willful misconduct of any Ionis Indemnitee except, in each case (Section 13.1.1 through Section 13.1.3), to the extent that any such claim results or arises from a matter for which Metagenomi is obligated to indemnify Ionis under Section 13.2 (Indemnification of Ionis by Metagenomi).

13.2.

Indemnification of Ionis by Metagenomi. Subject to Section 13.4 (Conditions to Indemnification), Metagenomi will defend, indemnify, and hold harmless Ionis and its Affiliates, Sublicensees, and Subcontractors, and their respective employees, officers, and directors (“Ionis Indemnitees”) from and against any and all Losses incurred or imposed upon the Ionis Indemnitees or any one of them in connection with one or more Third Party Claims arising out of or relating to:

13.2.3.

the Exploitation of any Licensed System or Licensed Product by or on behalf of any Metagenomi Indemnitee prior to the Effective Date and after termination of this Agreement;

13.4.

Conditions to Indemnification. Any Person seeking indemnification under this Article 13 (Indemnification; Limitation Of Liability; Insurance) (the “Indemnitee”) will give prompt written notice of the indemnity claim to the indemnifying Party and promptly provide a copy to the indemnifying Party of any complaint, summons, or other written or verbal notice that the Indemnitee receives in connection with any such claim. An Indemnitee’s failure to deliver written notice will relieve the indemnifying Party of liability to the Indemnitee under this Article 13 (Indemnification; Limitation Of Liability; Insurance) only to the extent such delay is prejudicial to the indemnifying Party’s ability to defend or settle such claim. The indemnifying Party will have the right to assume and control the defense of the indemnification claim at its own expense with counsel selected by the indemnifying Party and reasonably acceptable to the Indemnitee; provided, however, that an Indemnitee will have the right to retain its own counsel that is reasonably acceptable to the indemnifying Party, with the fees and expenses to be paid by the indemnifying Party, if representation of such Indemnitee by the counsel retained by the indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnitee and any other party represented by such counsel in such proceedings. The indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim. If the indemnifying Party does not assume the defense of the indemnification claim as described in this Section 13.4 (Conditions to Indemnification), then the Indemnitee may defend the indemnification claim but will have no obligation to do so. The Indemnitee will not settle or compromise the indemnification claim without the prior written consent of the indemnifying Party, and the indemnifying Party will not settle or compromise the indemnification claim in any manner which would have an adverse effect on the Indemnitee’s interests (including any rights under this Agreement or the scope, validity, or enforceability of any Patent Rights, Confidential Information, or other rights licensed to Ionis by Metagenomi hereunder), without the prior written consent of the Indemnitee, which consent, in each case (by the indemnifying Party or the Indemnitee, as the case may be), will not be unreasonably withheld, conditioned, or delayed. The Indemnitee will reasonably cooperate with the indemnifying Party at the indemnifying Party’s expense and will make available to the indemnifying Party all pertinent information under the control of the Indemnitee, which information will be subject to Article 11 (Confidentiality). The indemnifying Party will not be liable for any settlement or other disposition of the claims by the Indemnitee if such settlement is reached without the written consent of the indemnifying Party pursuant to this Section 13.4 (Conditions to Indemnification).

13.5.

Limited Liability. NEITHER OF THE PARTIES NOR THEIR RESPECTIVE AFFILIATES OR SUBLICENSEES WILL BE ENTITLED TO RECOVER FROM THE OTHER PARTY OR ITS AFFILIATES OR SUBLICENSEES ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES OR DAMAGES FOR LOSS OF PROFIT, LOST OPPORTUNITY, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES IN CONNECTION WITH THIS AGREEMENT, ITS PERFORMANCE OR LACK OF PERFORMANCE HEREUNDER, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE, OR ANY LICENSE GRANTED HEREUNDER, EXCEPT TO THE EXTENT THE DAMAGES RESULT FROM (A) A PARTY’S WILLFUL MISCONDUCT OR GROSS NEGLIGENCE UNDER THIS AGREEMENT, (B) A BREACH OF THE OBLIGATIONS OF A PARTY UNDER ARTICLE 11 (CONFIDENTIALITY) OR UNDER SECTION 3.6 (EXCLUSIVITY), OR (C) AMOUNTS REQUIRED TO BE PAID AS PART OF A CLAIM FOR WHICH A PARTY PROVIDES INDEMNIFICATION UNDER ARTICLE 13 (INDEMNIFICATION; LIMITATION OF LIABILITY; INSURANCE).

13.6.

Insurance Obligations. Each Party will, at its own expense, procure and maintain during the Term and for a period of [***] thereafter, insurance policies, including product liability insurance when applicable, adequate to cover its obligations hereunder and that are consistent with normal business practices of prudent companies similarly situated. Such insurance will not be construed to create a limit of a Party’s liability with respect to its indemnification obligations under this Article 13 (Indemnification; Limitation of Liability; Insurance). Each Party will provide the other Party with written evidence of such insurance. Notwithstanding any provision to the contrary set forth in this Agreement, Ionis may self-insure, in whole or in part, the insurance requirements described above.

Article 14

Term and Termination

14.1.

Term. This Agreement will commence on the Effective Date and, unless otherwise terminated pursuant to Section 14.2 (Termination), will continue (a) with respect to the Ionis Programs, on an Ionis Product-by-Ionis Product and country-by-country basis until the expiration of all applicable Royalty Terms for an Ionis Product in a country, (b) with respect to the Co-Co Programs for which Metagenomi has not exercised its Opt-Out Right in accordance with Section 5.4 (Metagenomi Opt- Out), on a Co-Co Program-by-Co-Co Program basis until the Parties cease all Exploitation for the Co-Co Products that are the subject to such Co-Co Program, and (c) with respect to the Metagenomi Products, on a Metagenomi Product-by-Metagenomi Product and country-by-country basis until the expiration of the Metagenomi Royalty Term for a Metagenomi Product in a country (the “Term”). On a Licensed Product-by-Licensed Product and country-by-country basis, effective upon the expiration of the Royalty Term for a Licensed Product in a country (but not upon any earlier termination of this Agreement for any reason), the licenses granted to Ionis will each become fully paid-up, royalty-free, irrevocable, and perpetual in such country with respect to such Licensed Product. On a Metagenomi Product-by-Metagenomi Product and country-by-country basis, effective upon the expiration of the Metagenomi Royalty Term for a Metagenomi Product in a country (but not upon any earlier termination of this Agreement for any reason), the licenses granted to Metagenomi will each become fully paid-up, royalty-free, irrevocable, and perpetual in such country with respect to such Metagenomi Product.

14.2.

Termination. This Agreement may be terminated as follows:

14.2.1.

Termination for Convenience by Ionis. Ionis may terminate this Agreement (either in its entirety or on a Licensed Product-by-Licensed Product basis), for convenience by providing written notice of its intent to terminate to Metagenomi, in which case, such termination will be effective 90 days after Metagenomi’s receipt of such written notice.

14.2.2.

Termination for Material Breach.

(a)

Ionis’ Right to Terminate. If Metagenomi is in material breach of this Agreement, then Ionis may deliver written notice of such material breach to Metagenomi. If the breach is curable, then Metagenomi will have [***] following its receipt of such written notice to cure such breach (except to the extent such breach involves the failure to make a payment when due, in which case such breach must be cured within [***] following Metagenomi’s receipt of such written notice). If Metagenomi fails to cure such breach within such [***] or [***] period, as applicable, or the breach is not subject to cure, then Ionis may terminate this Agreement solely with respect to those Licensed Products to which such material breach relates, or in its entirety if such material breach relates to all Licensed Products, by providing written notice to Metagenomi, in which case, this Agreement will terminate on the date on which Metagenomi receives such written notice; provided, however, that if (A) the relevant breach does not involve Metagenomi’s failure to make a payment when due and is curable, but not reasonably curable within [***], and (B) Metagenomi is making a bona fide effort to cure such breach, then Ionis’ right to terminate this Agreement on account of such breach will be suspended for up to an additional [***] so long as Metagenomi is continuing to make such bona fide effort to cure such breach. If such breach is successfully cured during the applicable cure period, then Ionis will no longer have the right to terminate this Agreement on account of such breach.

(b)

Metagenomi’s Right to Terminate. If Ionis is in material breach of this Agreement, then Metagenomi may deliver written notice of such material breach to Ionis. If the breach is curable, then Ionis will have [***] following its receipt of such written notice to cure such breach (except to the extent such breach involves the failure to make a payment when due, in which case such breach must be cured within [***] following Ionis’ receipt of such written notice). If Ionis fails to cure such breach within the [***] or [***] period, as applicable, or the breach is not subject to cure, then Metagenomi may terminate this Agreement in its entirety by providing written notice to Ionis, in which case this Agreement will terminate on the date on which Ionis receives such written notice; provided, however, that if (i) the relevant breach does not involve Ionis’ failure to make a payment when due and is curable, but not reasonably curable within [***], and Ionis is making a bona fide effort to cure such breach, then Metagenomi’s right to terminate this Agreement on account of such breach will be suspended for up to an additional [***] so long as Ionis is continuing to make such bona fide effort to cure such breach. If such breach is successfully cured during the applicable cure period, then Metagenomi will no longer have the right to terminate this Agreement on account of such breach. Notwithstanding the foregoing, any license granted to Ionis under this Agreement may not be terminated under this Section 14.2.2(b) (Metagenomi’s Right to Terminate) if (A) the material breach does not involve the failure to make any material and undisputed portion of a payment due to Metagenomi under Article 9 (Consideration; Financial Terms) and (B) such license is necessary to make, have made, use or sell a Licensed Product for which a Clinical Trial has been Initiated. Termination pursuant to this Section 14.2.2(b) (Metagenomi’s Right to Terminate) will not relieve Ionis from liability and damages to Metagenomi for default, and the Parties agree that if monetary damages are available to Metagenomi as a reasonable remedy for any default hereunder, then such monetary remedy will constitute the exclusive remedy for such default in lieu of termination of this Agreement.

(c)

Disputes Regarding Material Breach. Notwithstanding the foregoing, if the alleged breaching Party in Section 14.2.2(a) (Ionis’ Right to Terminate) or Section 14.2.2(b) (Metagenomi’s Right to Terminate) disputes in good faith the existence or materiality of any breach, or failure to cure any breach, and provides written notice to the non-breaching Party of such dispute within the relevant cure period, then the non-breaching Party will not have the right to terminate this Agreement in accordance with Section 14.2.2(a) (Ionis’ Right to Terminate) or Section 14.2.2(b) (Metagenomi’s Right to Terminate), as applicable, unless and until the relevant dispute has been resolved in accordance with Section 15.1 (Dispute Resolution). During the pendency of such dispute, all the terms of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder.

14.2.3.

Termination for Insolvency. If Metagenomi makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act, or has any such petition filed against it that is not discharged within [***] after the filing thereof (each, an “Insolvency Event”), then Ionis may terminate this Agreement in its entirety by providing written notice of its intent to terminate this Agreement to Metagenomi, in which case, this Agreement will terminate on the date on which Metagenomi receives such written notice.

14.3.

Effects of Termination. In the event of any early termination of this Agreement by a Party pursuant to Section 14.2 (Termination), effective as of the effective date of termination, the following provisions will apply with respect to the Terminated Products in the Terminated Countries:

14.3.1.

Wind-Down. During the applicable termination notice period, unless otherwise agreed by the Parties, the Parties will begin to wind-down their respective activities under this Agreement to the extent related to the Terminated Products in the Terminated Countries. The JSC will coordinate the wind-down of each Party’s efforts under this Agreement with respect to the Terminated Products in the Terminated Countries, or, if the JSC has disbanded, then the Parties will establish an appropriate committee to coordinate such wind-down.

14.3.2.

Termination of Rights and Licenses. Other than as expressly set forth herein, including those provisions that this Agreement expressly provides will survive such termination and subject to Section 14.3.8 (Sublicense Survival), all rights and licenses granted from one Party to the other hereunder will immediately terminate with respect to the Terminated Products in the Terminated Countries; 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 14.3.1 (Wind-Down).

14.3.3.

Termination of Payment Obligations. All payment obligations with respect to the Terminated Products in the Terminated Countries hereunder will terminate, other than those that are accrued and unpaid as of the effective date of such termination. For any payment obligations that are accrued and unpaid as of the effective date of termination, an invoice must be provided no later than [***] after the effective date of termination.

14.3.4.

Sell-Off Right. For a period not to exceed [***] following the effective date of termination, Ionis will have the right to sell or otherwise dispose of the Terminated Products in the Terminated Countries on hand at the time of such termination or in the process of Manufacturing; provided that any revenue obtained from such disposal will be treated as Net Sales and the provisions of Article 9 (Consideration; Financial Terms) will apply to such Net Sales and, if such sales result in the achievement of any Ionis Product Sales Milestone Event, then the applicable Ionis Product Sales Milestone Payment will be payable.

14.3.5.

Assignment of Regulatory Submissions. Except with respect to any termination by Ionis under Section 14.2.2(a) (Ionis’ Right to Terminate), Ionis will, as promptly as practicable, transfer to Metagenomi possession and ownership of all Regulatory Approvals solely relating to the Exploitation of any Terminated Product in the Terminated Countries.

14.3.6.

Reversion for Terminated Products other than Combination Products.

(a)

Reversion License Grant. Upon Metagenomi’s written request no later than [***] following the effective date of termination and agreement by the Parties of the applicable royalty rate pursuant to Section 14.3.6(c) (Reversion Royalties), Ionis will grant and agrees to grant to Metagenomi, an exclusive, royalty-bearing (solely as provided in Section 14.3.6(c) (Reversion Royalties)), right and license, with the right to grant sublicenses through multiple tiers, under Patent Rights and Know-How Controlled by Ionis or its Affiliates to the extent such Patent Rights or Know-How are actually being used on the date of such termination by the Parties in the Development, Commercialization, or other Exploitation of the Terminated Products in the Terminated Countries as such Terminated Products exist as of the effective date of termination, solely to Exploit such Terminated Products in the Terminated Countries; provided that, if any such Terminated Products are Combination Products, then such license will not include any license or other rights with respect to any Other Product that is Covered by Patent Rights Controlled by Ionis or any of its Affiliates and Metagenomi will not obtain a license to any such Other Product other than pursuant to Section 14.3.7 (Reversion for Certain Combination Products) (such license grant, the “Reversion License”).

(b)

Third Party Reversion IP. With respect to any Patent Rights or Know-How that are the subject of the Reversion License that are in-licensed by Ionis from Third Parties, Ionis will notify Metagenomi of such Patent Rights or Know-How that are sublicensable to Metagenomi under the Reversion License (which notice will describe the terms and conditions of any Third Party agreements that are applicable to the grant to Metagenomi of the Reversion Licenses under such Patent Rights or Know-How (any such agreement, a “Reversion IP In-License Agreement”), including applicable payment terms). If Metagenomi elects to receive a sublicense under any Reversion IP In-License Agreement, then Metagenomi will notify Ionis in writing and Metagenomi will be responsible for (i) making all payments (including royalties, milestones, and other amounts) that are payable by Ionis to the Third Parties under each Reversion IP In-License Agreement with respect to and allocable to the Patent Rights and Know-How that are the subject of the Reversion License and arising out of the Exploitation of the Terminated Products in the Terminated Countries by making such payments directly to Ionis and, in each instance, Metagenomi will make the requisite payments to Ionis and provide the necessary reporting information to Ionis in sufficient time to enable Ionis to comply with its obligations under each Reversion IP In-License Agreement, and (ii) complying with any other obligations included in each Reversion IP In-License Agreement that are applicable to the grant to Metagenomi of the Reversion License under the applicable Patent Rights or Know-How (provided that Ionis has notified Metagenomi of such obligations), and the granting by Metagenomi of a sublicense under the Reversion Licenses will not relieve Metagenomi of its obligations under subclauses (i) and (ii).

(c)

Reversion Royalties. The licenses granted to Metagenomi in Section 14.3.6(a) (Reversion License Grant) will be royalty-bearing, and Metagenomi will pay Ionis, on a Calendar Quarter basis, the royalty rates that are agreed to by the Parties at the time of Metagenomi’s written request delivered pursuant to Section 14.3.6(a) (Reversion License Grant). With respect to the royalty rates to be agreed to by the Parties pursuant to this Section 14.3.6(c) (Reversion Royalties), the Parties will take into account, among other things, (i) [***], (ii) [***], (iii) [***], and (iv) [***], and if the Parties have not reached agreement on such financial terms within [***] after such effective date of termination, then either Party may refer such matter for resolution pursuant to Section 15.1.3 (Expedited Dispute Resolution).

14.3.7.

Reversion for Certain Combination Products. If (a) any of the Terminated Products are Combination Products that are required, by the approved labeling for such Terminated Product, to be promoted as a Combination Product and the Other Product for such Terminated Product is exclusively Controlled by Ionis, such that Metagenomi is not able to otherwise acquire such Other Product, and (b) there is no approved label regarding the promotion of the Terminated Product that is not a Combination Product (any such Terminated Product meeting the requirements of (a) and (b), a “Terminated Combination Products”), then upon Metagenomi’s written request no later than [***] following the effective date of termination for such Terminated Combination Products, the Parties will enter into good faith negotiations for up to [***] regarding the grant of a non-exclusive, royalty-bearing right and license, with the right to grant sublicenses through multiple tiers, under Patent Rights and Know-How Controlled by Ionis or its Affiliates to the extent such Patent Rights or Know-How are actually being used on the date of such termination by the Parties in the Development, Commercialization, or other Exploitation of the Terminated Combination Products in the Terminated Countries as such Terminated Combination Products exist as of the effective date of termination, solely to Exploit such Terminated Combination Products in the Terminated Countries.

14.3.8.

Sublicense Survival. Any sublicense granted hereunder by Ionis will, at the Sublicensee’s option, survive such termination on the condition that the relevant Sublicensee is not in material breach of any of its obligations under such sublicense. In order to effect this provision, at the request of the Sublicensee, Metagenomi will enter into a direct license with the Sublicensee on terms that are substantially the same terms as the applicable terms of this Agreement; provided that Metagenomi will not be required to undertake obligations in addition to those required by this Agreement, and Metagenomi’s rights under such direct license will be consistent with its rights under this Agreement, taking into account the scope of the license granted under such direct license.

Miscellaneous

15.1.

Dispute Resolution.

15.1.1.

Escalation. In the event of any dispute, claim, controversy, or cause of action asserted by a Party against the other Party or by the Metagenomi Indemnitees against Ionis or by the Ionis Indemnitees against Metagenomi arising out of or related to this Agreement or performance of this Agreement (other than matters within the purview of the JSC, which will be resolved as set forth in Section 4.6 (Decision-Making)) (a “Claim”), including any alleged breach of this Agreement or claim for indemnification pursuant to Article 13 (Indemnification; Limitation Of Liability; Insurance), such Party may, by written notice to the other Party, refer such matter to the Parties’ respective officers designated below for attempted resolution (each, an “Executive Officer”):

For Ionis:

Chief Executive Officer (or such other senior executive designated by Ionis for such purpose)

For Metagenomi:

Chief Executive Officer (or such other senior executive designated by Metagenomi for such purpose)

15.1.2.

Arbitration. Except as otherwise expressly set forth in this Agreement, if such Executive Officers do not resolve the dispute within [***] after receipt of such request, then, either Party may at any time after such [***] period submit such Claim to be finally settled by arbitration administered in accordance with the procedural rules of the American Arbitration Association (the “AAA”) in effect at the time of submission, as modified by this Section 15.1.2 (Arbitration) (the “Arbitration”). The Arbitration will be governed by the Applicable Law of the State of New York. The Arbitration will be heard and determined by three arbitrators who are retired judges or attorneys with at least 20 years of relevant experience, each of whom will be impartial and independent and will not have worked for or on behalf of either Party for at least [***]. Each Party will appoint one arbitrator and the third arbitrator will be selected by the two Party-appointed arbitrators, or, failing agreement within [***] following appointment of the second arbitrator, by the AAA. Such Arbitration will take place in New York, NY. The Arbitration award so given will, absent an appealable error under applicable AAA procedural rules, be a final and binding determination of the Claim, will be fully enforceable in any court of competent jurisdiction, and will not include any damages expressly prohibited by Section 13.5 (Limited Liability). Ionis will pay the fees, costs, and expenses for the arbitrator it chooses, Metagenomi will pay the fees, costs, and expenses for the arbitrator it chooses, and the Parties will share payment of the fees, costs and expenses for the third arbitrator. Except in a proceeding to enforce the results of the Arbitration or as otherwise required by Applicable Law or securities exchange, neither Party nor any arbitrator may disclose the existence, content, or results of any Arbitration hereunder without the prior written consent of both Parties. The Parties will instruct the arbitrators to complete the Arbitration within [***] after selection of the first arbitrator by a Party and each Party will use reasonable efforts to complete such arbitration proceedings within such time period.

15.1.3.

Expedited Dispute Resolution. If the Executive Officers fail to reach agreement on any Expedited Dispute within [***] of submission of such Expedited Dispute to the Executive Officers, then either Party may notify the other Party of its intent to invoke dispute resolution under this Section 15.1.3 (Expedited Dispute Resolution) and such Expedited Dispute will be resolved by binding arbitration in accordance with this Section 15.1.3 (Expedited Dispute Resolution) except that the procedures for the conduct of such arbitration will be modified as follows:

(a)

The arbitration will be conducted by a single neutral arbitrator selected by the Parties or, failing agreement by the Parties, by the AAA in accordance with the procedural rules of the AAA. Such arbitrator will be a retired judge or attorney with at least 20 years of relevant experience, who will be impartial and independent and will not have worked for or on behalf of either Party for at least [***]. The arbitrator will have the authority to engage one or more Third Party experts who are expert in the subject matter of the dispute to advise the arbitrator in rendering his or her decision (each, a “Third Party Expert”), and the costs of such Third Party Expert(s) will be included in the costs of the arbitration. The arbitrator will seek to obtain the mutual agreement of the Parties regarding such Third Party Expert(s), but absent such agreement, such Third Party Expert(s) will be selected by the arbitrator. Each Third Party Expert will be a disinterested individual who is not affiliated with either Party or its Affiliates or a Sublicensee and who has expertise and experience with respect to the subject matter of the Expedited Dispute, as determined by the arbitrator. Neither the Third Party Expert nor any of the Third Party Expert’s former employers will be or have been at any time an Affiliate, employee, officer or director of, or a consultant for, either Party or any of its Affiliates or a Sublicensee.

(b)

Within [***] of appointment of the arbitrator (and selection of the Third Party Expert(s)) in accordance with this Section 15.1.3 (Expedited Dispute Resolution), the Parties will submit their written positions regarding the Expedited Dispute to the other Party and the arbitrator. Each Party may submit a revised written position to the arbitrator within [***] of receiving the other Party’s written position. If so requested by the arbitrator, each Party will make oral or other written submissions to the arbitrator in accordance with procedures to be established by the arbitrator; provided that the other Party will have the right to be present during any oral submissions.

(c)

The arbitrator will render a decision in writing within [***] (or such other time period as the Parties may agree) after receipt of the last Party’s written position, which decision will be in accordance with the applicable provisions of this Agreement, and such decision will be conclusive and binding on the Parties.

(d)

Notwithstanding anything to the contrary herein, the arbitration under this Section 15.1.3 (Expedited Dispute Resolution) will be conducted as a “baseball arbitration” type proceeding. The arbitrator will select one of the Party’s position as his or her decision, based on what is most reasonable and equitable to each of the Parties under the circumstances and in light of the terms set forth in this Agreement, and will not have the authority to render any substantive decision other than to so select one Party’s position as initially submitted, or as revised in accordance with the foregoing, as applicable. The arbitrator may fashion such detailed procedures as the arbitrator considers appropriate to implement this intent.

(e)

The Parties will instruct the arbitrator to complete all arbitration proceedings within [***] after selection of the arbitrator and each Party will use reasonable efforts to complete such arbitration proceedings within such time period.

15.1.4.

Tolling. The Parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel and laches), as well as all time periods in which a Party must exercise rights or perform obligation hereunder, will be tolled once the dispute resolution procedures set forth in this Section 15.1 (Dispute Resolution) have been initiated and for so long as they are pending, and the Parties will cooperate in taking all actions reasonably necessary to achieve such a result. In addition, during the pendency of any Claim under this Agreement initiated before the end of any applicable cure period, including under Section 14.2.2 (Termination for Material Breach), (a) this Agreement will remain in full force and effect, (b) the provisions of this Agreement relating to termination for material breach with respect to such Claim will not be effective, and (c) neither Party will issue a notice of termination pursuant to this Agreement based on the subject matter of the arbitration, until the arbitral tribunal has confirmed the material breach and the existence of the facts claimed by a Party to be the basis for the asserted material breach; provided that if such breach can be cured by (i) the payment of money, the defaulting Party will have an additional [***] within its receipt of the arbitral tribunal’s decision to pay such amount (or such later date if specified in the arbitral tribunal’s decision) or (ii) the taking of specific remedial actions, the defaulting Party will have a reasonably necessary period to diligently undertake and complete such remedial actions within such reasonably necessary period or any specific timeframe established by such arbitral tribunal’s decision before any such notice of termination can be issued. Further, with respect to any time periods that have run during the pendency of the Claim, the applicable Party will have a reasonable period of time or any specific timeframe established by such arbitral tribunal’s decision to exercise any rights or perform any obligations affected by the running of such time periods.

15.2.

Designation of Affiliates. Each Party may discharge any obligations and exercise any rights under this Agreement through delegation of its obligations or rights to any of its Affiliates; provided that the delegating Party will remain primarily responsible for such obligation. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and will cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement will be a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

15.3.

Patent Disputes. Notwithstanding Section 15.1.2 (Arbitration), if a dispute arises between the Parties under this Agreement with respect to the inventorship, interpretation, scope, validity, enforceability, applicability or term of any Patent Right, then such dispute will not be resolved pursuant to Section 15.1.2 (Arbitration), but instead may be brought by either Party in the federal courts in the State of New York.

15.4.

Injunctive Relief. Notwithstanding anything to the contrary set forth in this Agreement, the Parties each stipulate and agree that (a) the other Party’s Confidential Information includes highly sensitive trade secret information, (b) a breach of Section 3.6 (Exclusivity) or Article 11 (Confidentiality), in each case, may cause irrevocable harm for which monetary damages would not provide a sufficient remedy, and (c) in such case of a breach of Section 3.6 (Exclusivity) or Article 11 (Confidentiality), the non-breaching Party will be entitled to equitable relief (including temporary or permanent restraining orders, specific performance or other injunctive relief) from any court of competent jurisdiction. In addition, and notwithstanding anything to the contrary set forth in this Agreement, in the event of any other actual or threatened breach hereunder, the aggrieved Party may seek equitable relief (including temporary or permanent restraining orders, specific performance or other injunctive relief) from any court of competent jurisdiction without first submitting to the dispute resolution procedures set forth in Section 15.1 (Dispute Resolution).

15.5.

Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York without taking into consideration any choice of law principles that would lead to the application of the laws of another jurisdiction.

15.6.

Cumulative Remedies. The rights and remedies of the Parties under this Agreement are cumulative and not exclusive and, accordingly, are in addition to and not in lieu of any other rights and remedies of the Parties at law or in equity.

15.7.

Notices. Any notice or report required or permitted to be given or made under this Agreement by either Party to the other will be in writing and delivered to the other Party at its address indicated below or to such other address as the addressee will have theretofore furnished in writing to the addressor by hand, courier or by registered or certified airmail (postage prepaid), in writing, by registered or certified airmail (postage prepaid):

15.8.

Amendment; Waiver. This Agreement (including all exhibits and attachments to this Agreement except as set forth in Section 2.2.3 (Amendments to the Drug Discovery Plans) or Section 2.3.2 (Amendments to the Exploratory Research Plan)), may be amended, modified, superseded, or cancelled only by a written agreement between the Parties, and any of the terms of this Agreement may be waived only by a written instrument executed by each Party or, in the case of waiver, by the Party or Parties waiving compliance. The delay or failure of either Party at any time or times to require performance of any provisions will in no manner affect the rights at a later time to enforce the same. No waiver by either Party of any condition or of the breach of any term contained in this Agreement, whether by conduct, or otherwise, in any one or more instances, will be deemed to be, or considered as, a further or continuing waiver of any such condition or of the breach of such term or any other term of this Agreement.

15.9.

Assignment and Successors. Neither Party may assign or transfer this Agreement in whole or in part or the licenses granted under this Agreement without the other Party’s prior written consent unless such assignment is to (a) a Third Party successor or purchaser of all or substantially all of the assets or businesses to which this Agreement relates whether pursuant to a sale of assets, merger, or other transaction, in which case the assigning Party will provide prior written notice to the other Party and need not obtain the other Party’s consent or (b) an Affiliate of such Party, in which case the assigning Party will provide prior written notice to the other Party and need not obtain the other Party’s consent; provided that, in either case, the assigning Party remains fully liable for the performance of its obligations hereunder by such assignee. Each Party will also have the right to sell, assign, and convey its rights to receive royalties from Net Sales of Licensed Product (with respect to Metagenomi) and Metagenomi Products (with respect to Ionis) and related rights to receive royalty reports and conduct audits of the other Party, its Affiliates and Sublicensees to Third Party purchasers of royalty interests. Any other assignment of this Agreement by a Party requires the prior written consent of the other Party. An assignment to an Affiliate will terminate, and all rights so assigned will revert to the assigning Party, if and when such Affiliate ceases to be an Affiliate of the assigning Party. For clarity, any assignment in violation of this Section 15.9 (Assignment and Successors) will be null, void, and of no legal effect. This Agreement will be binding upon and inure to the benefit of the Parties and their respective legal representatives, successors and permitted assigns.

15.10.

Rights in Bankruptcy.

15.10.1.

All rights and licenses now or hereafter granted by one Party to the other Party under or pursuant to this Agreement, including, for the avoidance of doubt, the licenses granted to Ionis pursuant to Section 3.1 (License Grant to Ionis), are, for all purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined in the U.S. Bankruptcy Code. Upon the occurrence of any Insolvency Event with respect to a Party granting a license (the “Licensing Party”), the Licensing Party agrees that the other Party (the “Licensee”), as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. Without limiting the generality of the foregoing, the Parties intend and agree that any sale of a Licensing Party’s assets under Section 363 of the U.S. Bankruptcy Code will be subject to Ionis’ rights under Section 365(n), that the Licensee cannot be compelled to accept a money satisfaction of its interests in the intellectual property licensed pursuant to this Agreement, and that any such sale therefore may not be made to a purchaser “free and clear” of the Licensee’s rights under this Agreement and Section 365(n) without the express, contemporaneous consent of the Licensee. The Licensing Party will, during the Term, create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all intellectual property licensed under this Agreement. Each Party acknowledges and agrees that “embodiments” of intellectual property within the meaning of Section 365(n) include laboratory notes and notebooks, cell lines, laboratory samples, product samples and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference therein, marketing advertising and promotional materials, the Licensed Technology, and all information related to the Licensed Technology. If (a) a case under the U.S. Bankruptcy Code is commenced by or against a Licensing Party, (b) this Agreement is rejected as provided in the U.S. Bankruptcy Code, and (c) the Licensee elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, the Licensing Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(a)

provide the Licensee with all such intellectual property (including all embodiments thereof) held by the Licensing Party and such successors and assigns, or otherwise available to them, immediately upon Ionis’ written request. Whenever the Licensee or any of its successors or assigns provides to Ionis any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 15.10.1, the Licensee will have the right to perform the Licensing Party’s obligations hereunder with respect to such intellectual property, but neither such provision nor such performance by the Licensee will release the Licensing Party from liability resulting from rejection of the license or the failure to perform such obligations; and

(b)

not interfere with the Licensee’s rights under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy Code.

15.10.2.

All rights, powers and remedies of the Licensee provided herein are in addition to and not in substitution for any other rights, powers, and remedies now or hereafter existing at law or in equity (including the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S. Bankruptcy Code with respect to the Licensing Party. The Parties intend the following rights to extend to the maximum extent permitted by Applicable Law, and to be enforceable under U.S. Bankruptcy Code Section 365(n):

(a)

the right of access to any intellectual property rights (including all embodiments thereof) of the Licensing Party, or any Third Party with whom the Licensing Party contracts to perform an obligation of the Licensing Party under this Agreement, and, in the case of any such Third Party, which is necessary for the Manufacture, use, sale, import, or export of Licensed Systems and Licensed Products; and

(b)

the right to contract directly with any Third Party to complete the contracted work.

15.11.

Force Majeure. Neither Party will be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this Agreement to the extent such failure or delay is due to force majeure. For purposes of this Agreement, “Force Majeure” is defined as any cause beyond the reasonable control of the affected Party and without the fault or negligence of such Party, which may include acts of God; material changes in Applicable Law; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; pandemic; quarantine; and failure of public utilities or common carriers. The Parties agree the effects of the COVID-19 pandemic that is ongoing as of the Effective Date (including related government orders) may be invoked as a Force Majeure for the purposes of this Agreement, even though the pandemic is ongoing, only to the extent those effects are not reasonably foreseeable by the Parties as of the Effective Date. Notwithstanding the foregoing, a Party will not be excused from making payments owed hereunder due to any Force Majeure circumstances affecting such Party. In the case of a Force Majeure, the Party affected by such Force Majeure will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of [***], after which time the Parties will promptly meet to discuss in good faith how to best proceed in a manner that maintains and abides by the Agreement. To the extent possible, the Party affected by such Force Majeure will use reasonable efforts to minimize the duration of any Force Majeure.

15.12.

Interpretation. The Parties 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 will not be employed in the interpretation of this Agreement; and (c) the terms and provisions of this Agreement will be construed fairly as to each Party and not in a favor of or against either Party, regardless of which Party was generally responsible for the preparation of this Agreement. In addition, except as otherwise explicitly specified to the contrary, (i) references to a section, schedule or exhibit means a section of, or schedule or exhibit to this Agreement, unless another agreement is specified, (ii) the word “including” (in its various forms) means “including without limitation,” (iii) the words “shall” and “will” have the same meaning, (iv) references to a particular statute or regulation include all rules and regulations thereunder and any predecessor or successor statute, rules or regulations, in each case as amended or otherwise modified from time-to-time, (v) words in the singular will be held to include the plural and vice versa, and words of one gender will be held to include all genders as the context requires, (vi) references to a particular Person include such Person’s successors and assigns to the extent not prohibited by this Agreement, (vii) references to “days” will mean calendar days, unless otherwise specified, (viii) the word “or” will not be exclusive, unless the context otherwise requires, (ix) the titles and headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation of this Agreement, (x) the terms “hereof,” “hereby,” “hereto,” and derivative or similar words refer to this entire Agreement, including any schedules or exhibits hereto, and (xi) unless otherwise specified, “$” is in reference to United States Dollars.

15.13.

Integration. This Agreement, together with all exhibits and schedules attached hereto and each Co-Development and Co-Commercialization Agreement, any Development Supply Agreement, and any Commercial Supply Agreement, sets forth the entire agreement with respect to the subject matter hereof and thereof and supersedes all other agreements and understandings between the Parties with respect to such subject matter, including the Confidentiality Agreement.

15.14.

Severability. Each Party hereby agrees that it does not intend to violate any public policy, statutory or common laws, rules, regulations, treaty, or decision of any government agency or executive body thereof of any country or community or association of countries. If one or more provisions of this Agreement be or become invalid, then the Parties will substitute, by written agreement, valid provisions for such invalid provisions, which valid provisions in their economic effect are sufficiently similar to the invalid provisions such that it can be reasonably assumed that the Parties would have entered into this Agreement with such valid provisions. If the Parties are unable to agree upon such alternative valid provision, then the invalidity of one or several provisions of this Agreement will not affect the validity of this Agreement as a whole, unless the invalid provisions are of such essential importance to this Agreement such that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid provisions.

15.15.

Further Assurances. Each of Ionis and Metagenomi agrees to duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including, the filing of such additional assignments, agreements, documents and instruments, as the other Party may at any time and from time-to-time reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes of, or to better assure and confirm unto such other Party its rights and remedies under, this Agreement.

15.16.

Counterparts. This Agreement may be executed in counterparts, all of which taken together will be regarded as one and the same instrument. Counterparts may be delivered via electronic mail, including Adobe™ Portable Document Format (PDF) or any electronic signature complying with the U.S. Federal ESIGN Act of 2000, and any counterpart so delivered will be deemed to be original signatures, will be valid and binding upon the Parties, and, upon delivery, will constitute due execution of this Agreement.

15.17.

Relationship of the Parties. In entering into this Agreement and performing their respective duties and obligations with respect to the Agreement, the Parties are acting, and intend to be treated, as independent entities, and the activities and resources of each Party will be managed by such Party, acting independently and in its individual capacity. The relationship between the Parties is that of independent contractors, and neither Party will have the power to bind or obligate the other Party in any manner. Nothing contained in this Agreement will be construed or implied to create an agency, partnership, joint venture, fiduciary, or employer-employee relationship between the Parties. Except as otherwise expressly provided in this Agreement, neither Party may make any representation, warranty or commitment, whether express or implied, on behalf of or incur any charges or expenses for or in the name of the other Party. Neither Party will hold itself out, or take any action, contrary to the terms of this Section 15.17 (Relationship of the Parties), and neither Party will become liable due to any such representation, warranty, commitment, act or omission made by the other Party contrary to the provisions of this Section 15.17 (Relationship of the Parties). Subject to the terms of this Agreement, the activities and resources of each Party will be managed by such Party, acting independently and in its individual capacity.

(a)

normal and customary trade, quantity or prompt settlement discounts (including initial launch stocking discounts, chargebacks, and allowances) actually allowed, provided that such discounts are not applied disproportionately to such Licensed Product or Metagenomi Product when compared to the other products of the Selling Party;

(b)

amounts repaid or credited by reason of rejection, returns or recalls of goods, rebates or bona fide price reductions determined by the Selling Party in good faith;

(c)

rebates and similar payments made with respect to sales paid for by any Governmental Authority such as, by way of illustration and not in limitation of the Parties’ rights hereunder, Federal or state Medicaid, Medicare or similar state program in the United States or equivalent governmental program in any other country;

(d)

refunds or clawbacks of a portion of payments previously paid by the Selling Party for not achieving a predetermined metric or term in an outcome-based contracts;

(e)

any invoiced amounts that are not collected by the Selling Party, including bad debts, (applied to Net Sales in the period in which such receivables are written off), provided that any such amounts subsequently collected will be included in Net Sales for the period collected;

(f)

excise taxes, value added taxes, sales taxes, consumption taxes and other similar taxes (excluding any income, franchise, or withholding taxes), customs duties, customs levies and import fees imposed on the sale, importation, use or distribution of the Licensed Product, including fees paid pursuant to Section 9008 of the Patient Protection and Affordable Care Act that the Selling Party allocate to sales of the Licensed Product or Metagenomi Product (as applicable) in accordance with such Selling Party’s standard policies and procedures consistently applied across its products, as applicable; and

an allowance for transportation costs, distribution expenses, special packaging, insurance charges, and storage and warehousing costs.

Net Sales (including any deductions) will be calculated using the Selling Party’s internal audited systems used to report such sales as adjusted for any of the items above not taken into account in such systems, fairly applied and as employed on a consistent basis throughout such Selling Party’s operations. To the extent any accrued amounts used in the calculation of Net Sales are estimates, such estimates will be trued-up to actuals (including that, for any estimates of deductions that are later decreased, the difference will be added back to Net Sales). In no event will any particular amount identified above be deducted more than once in calculating Net Sales (i.e., no “double counting” of deductions).

In the case of any sale or other disposal of a product between or among such Party or its Affiliates or Sublicensees for resale, Net Sales will be calculated only on the value charged or invoiced on the first arm’s-length sale thereafter to a Third Party (other than a Sublicensee). In the case of any sale that is not invoiced or is delivered before invoice, Net Sales will be calculated at the time all the revenue recognition criteria under such Party’s Accounting Standards are met. In the case of any sale or other disposal for value, such as barter or counter-trade, of any Licensed Product or Metagenomi Product (as applicable), or part thereof, other than in an arm’s-length transaction exclusively for money, Net Sales will be calculated on the value of the non-cash consideration received or the fair market price (if higher) of such Licensed Product(s) or Metagenomi Product(s) (as applicable) in the country of sale or disposal. Notwithstanding the foregoing, the following will not be included in Net Sales: (1) sales between or among a Party and its Affiliates or Sublicensees (but Net Sales will include sales to the first Third Party (other than a Sublicensee) by a Party or its Affiliates or Sublicensees); and (2) any named patient sales or any sale or other distribution at cost or less than cost for use in any Clinical Trial, for bona fide charitable purposes, test marketing program, or for compassionate use.

Solely for purposes of calculating Net Sales, if the Selling Party sells a Licensed Product or Metagenomi Product (as applicable) in the form of a combination product containing a Licensed System or Metagenomi System (as applicable) and one or more other therapeutically or prophylactically active ingredients or delivery devices that is not a Licensed System or Metagenomi System (as applicable) (“Other Product”) (whether combined in a single formulation or package, as applicable, or formulated separately but packaged under a single label approved by a Regulatory Authority and sold together for a single price) (such combination product, a “Combination Product”), Net Sales of such Combination Product for the purpose of determining the payments due to the other Party pursuant to this Agreement will be calculated by [***]. If the gross selling price of a Licensed Product or Metagenomi Product (as applicable) containing such Licensed System or Metagenomi System (as applicable) in such country when sold separately in finished form (i.e., without the other active ingredients or delivery device) can be determined but the gross selling price of the Other Product in such country cannot be determined, then Net Sales in such country for purposes of determining royalty payments will be calculated by [***]. If such separate sales are not made in a country, then Net Sales will be calculated by [***].

If a license agreement or collaboration agreement that is negotiated in an arm’s length transaction with an Sublicensee includes a definition of “Net Sales” that differs in any material respect from the definition contained in this Section 1.190 (Net Sales), then the Parties will discuss such material differences and will use reasonable efforts to negotiate in good faith any reasonable modifications to this Section 1.190 (Net Sales) that are necessary to avoid any ambiguity in the calculation of the royalty payment due to a Party under this Agreement for sales of Licensed Products or Metagenomi Products by such Sublicensee.
