5.5.8 During the Backup Research Term, Kymera will furnish to the JRDC, within [***], an update on Kymera’s progress under the Backup Research Plan for the applicable Collaboration Target during the relevant Calendar Quarter, including a summary of any results and data generated by Kymera under such Backup Research Plan and an overview of the resources (including an overview of FTEs used by such Party for such Backup Research activities) allocated to activities under such Backup Research Plan during the relevant Calendar Quarter. Kymera will provide the JRDC with such other information, results and data with respect to the Backup Research activities under the Backup Research Plan as any member of the JRDC may reasonably request that are in Kymera’s possession or control. Kymera will provide Sanofi a reasonable opportunity via the JRDC to discuss and provide input with respect to Kymera’s Backup Research activities under the Backup Research Plan, including with respect to the prioritization of Backup Research activities.

5.5.9 In addition to, and without limiting, the reporting requirements in Section 5.5.8, during the Backup Research Term, Kymera will furnish to the JRDC, within [***], a written report on Kymera’s Backup Research activities with respect to Collaboration Compounds that are Researched under Section 5.5.5 and have the potential to be classified as Backup Degraders. Such reports will [***].

5.5.10 During the Backup Research Term, within [***] after Kymera reasonably believes that it has identified a Collaboration Compound that satisfies all of the Backup Degrader Criteria, Kymera will present a written report to Sanofi that identifies such Collaboration Compound and [***]. Sanofi may, in its discretion and through the JRDC, request any other information, results or data with respect to such Collaboration Compound as set forth more fully in Section 5.9.2. Within [***] after the delivery of such report (or such longer period of time as may be reasonably determined by the JRDC, but in no event longer than [***]), the JRDC will (a) meet, discuss and review the report and associated data, results and information and (b) determine whether such Collaboration Compound satisfies the Backup Degrader Criteria. If the JRDC determines that such Collaboration Compound satisfies the Backup Degrader Criteria, then such Collaboration Compound will be classified as a “Backup Degrader” under this Agreement. If the JRDC does not believe that such Collaboration Compound satisfies the Backup Degrader Criteria, then Kymera will use diligent efforts to conduct additional Research activities during the remainder of the Backup Research Term in accordance with the Backup Research Plan, and thereafter present a report to the JRDC as and to the extent applicable in this Section 5.5.10. In the event that the JRDC does not agree on whether such Collaboration Compound satisfies the Backup Degrader Criteria, then such dispute will be resolved in accordance with Section 9.9.2(b). Notwithstanding the foregoing, Sanofi may determine, in its sole discretion, that a Collaboration Compound that satisfies at least certain of the Backup Degrader Criteria during the Backup Research Term will be selected as a “Backup Degrader” notwithstanding that it does not satisfy all of the Backup Degrader Criteria. Any selection of a Collaboration Compound as a Backup Degrader by the JRDC, by the R&D Expert in accordance with Section 9.9.2(b), or by Sanofi pursuant to the preceding sentence, will be recorded in the minutes of the JRDC.

5.5.11 In the event that Sanofi has provided written notice to Kymera (including via the JRDC) that [***], then, within [***] of the date of receipt of such written notice, Kymera will permit Sanofi to examine the relevant books and records of Kymera and its Affiliates, as may be reasonably necessary to verify the Backup Research updates and progress reports submitted by Kymera in accordance with Section 5.5; provided that such examination will be subject to customary and reasonable due diligence procedures to preserve the confidential nature of any books or records. An examination by Sanofi under this Section 5.5.11 (a) will occur not more than [***], (b) will be limited to the pertinent books and records for any Calendar Year ending not more than [***] before the date of the written notice, (c) will be conducted in such a manner to minimize, to the extent reasonably possible, the period of examination and in no case shall such period exceed [***], and (d) will be conducted by the minimum number of Sanofi employees as necessary to provide requisite subject matter expertise and conduct the review in the allotted timeframe, each of whom shall have appropriate experience in the Research of small molecule compounds and candidates; provided, that if any examination by Sanofi under this Section 5.5.11 reveals any material discrepancy, Kymera will permit Sanofi to conduct additional examination of pertinent books and records for Calendar Years ending not more than [***] before the date of the written notice, during a period limited to minimize the days of examination as much as possible and in no case more than an additional [***]. Sanofi will be provided access to such books and records at Kymera’s facility or facilities where such books and records are normally kept and such examination will be conducted during Kymera’s normal business hours. Upon completion of the examination, Sanofi will provide Kymera and the JRDC a written report disclosing the reason(s) for the difference between the relevant report provided by Kymera and the results and data that should have been generated and the activities that should have been conducted by Kymera during the relevant time. The costs and fees of any examination conducted by Sanofi under this Section 5.5.11 will be borne by Sanofi.

5.5.12 Notwithstanding anything herein to the contrary, in no event will Kymera be required to conduct any Development activities for any Backup Degraders.

The applicable royalty rate set forth in the applicable table above will apply only to that portion of the Net Sales of a given Licensed Product during a given Calendar Year that falls within the indicated range. By way of example and without limitation of this Section 11.3.1, if Calendar Year Net Sales by Sanofi, its Affiliates and Sublicensees of a given Licensed Product Directed Against Collaboration Target 2 were [***], then the royalties payable with respect to such Calendar Year Net Sales for such Licensed Product for such Calendar Year, subject to adjustment as set forth in this Section 11.3.1, would be: [***].

Notwithstanding the foregoing, on a Collaboration-by-Collaboration Target basis, in the event that Kymera exercised the Kymera Opt-In Right and later exercises the Kymera Opt-Out Right, the royalty rates will be as follows:

[***].

11.3.2 Royalty Term. Sanofi will pay royalties to Kymera under this Section 11.3 on a Licensed Product-by-Licensed Product and a country-by-country basis during the Royalty Term for such Licensed Product in such country. Upon the expiration of the Royalty Term for a given Licensed Product in a given country, the Exclusive License granted to Sanofi under Section 10.1 will become fully-paid, perpetual, irrevocable and royalty free with respect to such Licensed Product.

11.3.3 Reduction for Lack of Patent Coverage. If during any period within the applicable Royalty Term for a country, no Valid Claim of any Patent within the Licensed Technology (which includes, for clarity, the Joint Foreground Patents) exists that Covers the sale or use of such Licensed Product in such country, then the royalty rate applied to Net Sales of such Licensed Product in such country will be reduced by [***] for purposes of calculating the royalty owed under Section 11.3.1 for the remainder of the Royalty Term for such Licensed Product in such country.

11.3.4 Reduction for Competition.

(a) Following the First Commercial Sale of a Generic Product in a given country, if during any Calendar Quarter during the Royalty Term for a Licensed Product in such country, the average quarterly Net Sales of Licensed Product sold during such Calendar Quarter declines [***] or more when compared to the average quarterly Net Sales of such Licensed Product in such country during the [***] immediately prior to the First Commercial Sale of such Generic Product, then the royalty rate with respect to Net Sales of such Licensed Product in such country will automatically be reduced to [***] of the royalty rate otherwise applicable with respect to such Licensed Product in such country for such Calendar Quarter.

(b) Further, following the First Commercial Sale of a Generic Product in a given country, if during any Calendar Quarter during the Royalty Term for a Licensed Product in such country, the average quarterly Net Sales of Licensed Product sold [***] declines [***] or more when compared to the average quarterly Net Sales of such Licensed Product in such country during the [***] immediately prior to the First Commercial Sale of such Generic Product, then the royalty rate with respect to Net Sales of such Licensed Product will automatically be reduced [***] with respect to such Licensed Product in such country.

11.3.5 Third Party Licenses. Sanofi may deduct from the royalties payable to Kymera under Section 11.3 [***] of any Blocking Third Party Intellectual Property Costs and In-License Costs paid by Sanofi prior to or during such Calendar Quarter; provided, however, that in no event will the royalties that would otherwise be payable to Kymera with respect to Net Sales of Licensed Products, after any applicable reduction to such Net Sales under this Section 11.3.5, be reduced by more than [***] in any given Calendar Quarter.

11.3.6 Aggregate Limitation on Deductions. Notwithstanding Sections 11.3.3, 11.3.4(a), and 11.3.5, in no event will the combined effect of all reductions to the royalties payable to Kymera under Sections 11.3.3, 11.3.4(a) and 11.3.5 reduce the royalty amounts payable by Sanofi to Kymera under this Section 11.3 for any Licensed Product in any country during a Calendar Quarter to less than [***] of the amount that would otherwise be due under Section 11.3.1, but for such deductions provided, that Sanofi will be entitled to [***]; provided that notwithstanding the foregoing, on a Collaboration Target-by-Collaboration Target basis, [***].

11.3.7 Opt-In Right. Notwithstanding anything to the contrary in this Section 11.3, on a Collaboration Target-by-Collaboration Target basis, if Kymera has exercised the Kymera Opt-In Right with respect to a given Collaboration Target, then, during the applicable Opt-In Period, (a) the Parties will share costs and profits in the United States with respect to Licensed Products Directed Against such Collaboration Target in accordance with the applicable Cost/Profit Sharing Agreement and (b) the terms of Sections 11.3.1 through 11.3.6 and 11.3.8 will apply to sales of Licensed Products Directed Against such Collaboration Target in the Rest of World. For clarity, in the event Kymera exercises the Kymera Opt-In Right with respect to a given Collaboration Target and later exercises the Kymera Opt-Out Right with respect to such Collaboration Target, then the terms of Sections 11.3.1 through 11.3.6 and 11.3.8 will apply to sales of Licensed Products Directed Against such Collaboration Target throughout the Territory. Further, any relevant Blocking Third Party Intellectual Property Costs paid by Sanofi will be subject to the relevant Cost/Profit Sharing Agreement.

11.3.8 Royalty Reports. Following the First Commercial Sale of a Licensed Product and continuing for the remainder of the Royalty Term for such Licensed Product, within [***] after the end of each Calendar Quarter, Sanofi will deliver a report to Kymera specifying on a Licensed Product-by-Licensed Product basis: (a) Net Sales in the relevant Calendar Quarter, (b) to the extent such Net Sales include sales not denoted in U.S. Dollars, a summary of the then-current exchange rate methodology then in use by Sanofi and used to convert Net Sales to U.S. Dollars, and (c) royalties payable on such Net Sales. All royalty payments due under Section 11.3 for each Calendar Quarter will be due and payable within [***] after the end of each Calendar Quarter.

11.4 Invoicing for Additional Amounts. With respect to any amounts owed under this Agreement by one Party to the other Party for which no other invoicing and payment procedure is specified elsewhere in this Agreement, within [***] after the end of each Calendar Quarter, the applicable Party will provide an invoice, together with reasonable supporting documentation, to the other Party for such amounts owed. The owing Party will pay any undisputed amounts within [***] of receipt of the invoice, and any disputed amounts owed by the owing Party will be paid within [***] of resolution of the Dispute.

11.5 In-License Agreements.

11.5.1 Potential In-Licenses.

(a) On a Collaboration Target-by-Collaboration Target basis, a Party may notify the JSC that the Research, Development, Manufacture or Commercialization of Collaboration Compounds, Collaboration Candidates or Licensed Products Directed Against a given Collaboration Target may require or benefit from a grant of rights under additional Patents or Know-How of Third Parties, whether by license or acquisition (each, a “Potential In-License”).

(b) If the Third Party Know-How or Patents that are the subject of the Potential In-License would constitute [***], then [***], in which case such Potential In-License will be deemed to be a “Collaboration In-License” upon the execution of such agreement, or (ii) follow the procedures set forth in Section 11.5.2.

(c) Except as set forth in Section 11.5.1(b)(i), if the Third Party Know-How or Patents that are subject to the Potential In-License either (x) [***] or (y) [***], the Parties will, through the JSC (in coordination with the JPC), review, discuss, and determine whether to negotiate the terms of such Potential In-License for use by the Parties pursuant to this Agreement with respect to the Research, Development, Manufacture or Commercialization of Collaboration Compounds, Collaboration Candidates or Licensed Products Directed Against such Collaboration Target to which such Potential In-License relates. In connection therewith, except as otherwise expressly agreed by the Parties, the JSC will:

(i) [***];

(ii) [***];

(iii) [***]; and

(iv) [***].

(d) If the Potential In-License relates to Patents or Know-How of Third Parties that are not otherwise covered in clause (b) or (c) above, then either Party will have the right, but not the obligation, to negotiate and enter into the applicable Potential In-License. Promptly after execution of any such Potential In-License, (i) the Parties will enter into a common interest agreement, and (ii) the applicable licensing Party will bring such Potential In-License to the attention of the JSC in accordance with Section 11.5.2.

(e) Notwithstanding anything to the contrary set forth in this Agreement, neither Party in its role as “lead negotiator” will negotiate for or agree to economic terms in any such Potential In-License in a manner that [***].

11.5.2 Collaboration In-License Agreements. If a Potential In-License is brought to the attention of the JSC pursuant to this Section 11.5, then the Parties will, through the JSC, [***]. The JSC will review and discuss the rationale of including such Potential In-License for use by the Parties with respect to the applicable Collaboration Compounds, Collaboration Candidates or Licensed Products Directed Against a given Licensed Target pursuant to this

Agreement and the proposed (or agreed) economics associated with doing so (including related royalty or milestone obligations), and determine whether to approve such Potential In-License as a Collaboration In-License Agreement for the applicable Collaboration Target. For any Potential In-License that the JSC approves for use by the Parties pursuant to this Agreement, (a) such Potential In-License will be deemed to be a “Collaboration In-License Agreement” hereunder on the date such agreement is executed by the applicable Party and Third Party, and (b) as of such execution date, the Patents and Know-How in-licensed under such Collaboration In-License Agreement will be deemed “Controlled” under this Agreement as Licensed Technology or Sanofi Technology for purposes of the Research, Development, Manufacture and Commercialization of Collaboration Compounds, Collaboration Candidates and Licensed Products Directed Against the applicable Collaboration Target.

11.5.3 Costs for Collaboration In-Licenses. Any upfront payments, milestone payments, similar payments or royalties incurred under a Collaboration In-License that are specific to the Collaboration Compounds, Collaboration Candidates or Licensed Products Directed Against the applicable Collaboration Target will be allocated between the Parties as follows:

[***]

11.5.4 Non-Approved Potential In-Licenses. If the JSC does not approve a Potential In-License as a Collaboration In-License Agreement pursuant to Section 11.5.1(c)(iv), then (a) such Potential In-License will not be a Collaboration In-License Agreement hereunder, and (b) the Patents and Know-How which would have been in-licensed under such Potential In-License will not be included as Licensed Technology or Sanofi Technology and will not be “Controlled” by the Party to the Potential In-License for purposes of this Agreement. For clarity, if the JSC does not approve a Potential In-License, then (a) each Party will be entitled to, at its discretion, independently in-license such Third Party Know-How or Patents provided that such independently-obtained license would not block the other Party from seeking its own direct license to such Intellectual Property for use in connection with the Research, Development, Manufacture or Commercialization of Collaboration Compounds, Collaboration Candidates or Licensed Products, and (b) the other Party will have no obligation to reimburse the other Party for any costs or expenses incurred or payments due with respect to any licenses between such Party and such Third Party.

11.5.5 Existing Third Party Agreement. Notwithstanding the foregoing, the Parties acknowledge and agree (a) Kymera will have the right to amend the Existing Third Party Agreement after the Effective Date without the prior written consent of Sanofi except as expressly set forth in Section 13.5(h); (b) no (sub)license or other right with respect to any Know-How or Patents owned by Kymera (whether solely or jointly with the Counterparty) pursuant to the Existing Third Party Agreement is granted to Sanofi pursuant to this Agreement; and (c) any Know-How or Patents co-owned by Kymera and the Counterparty under the Existing Third Party Agreement will not be Controlled by Kymera or its Affiliates for purposes of this Agreement except as provided in this Section 11.5.5. In the event that the Parties wish to use or incorporate any of the Know-How or Patents co-owned by Kymera and the Counterparty into or under this Agreement, then the Parties may amend this Agreement to incorporate such rights, licenses and other obligations as the Parties may mutually agree in writing.

11.5.6 Compliance with Collaboration In-License Agreements. All licenses and other rights granted under this Agreement will be subject to the rights and obligations under the applicable Collaboration In-License Agreements. Each Party will comply with all applicable provisions of the Collaboration In-License Agreements, and will perform and take such actions as may be required to allow the other Party to comply with its obligations thereunder, including obligations relating to sublicensing, patent matters, confidentiality, reporting, audit rights, indemnification and diligence. Without limiting the foregoing, each Party will prepare and deliver to the other Party any additional reports required under the applicable Collaboration In-License Agreements and reasonably requested by the other Party, in each case, sufficiently in advance to enable the other Party to comply with its obligations under the applicable Collaboration In-License Agreements. For clarity, as of the Execution Date, there are no Collaboration In-License Agreements, and the Existing Third Party Agreement will not be deemed a Collaboration In-License Agreement, unless the Parties mutually agree otherwise in writing.

11.6 Research and Development Funding Reimbursement.

11.6.1 Research Costs for First Additional Degraders during the FAD Term Extension. Sanofi will reimburse Kymera for its [***] actually incurred by Kymera or its Affiliates for the Research activities conducted under Section 2.4.2 during the FAD Term Extension in accordance with the Research Plan.

11.7 Payment Terms.

11.7.1 Currency; Payment Method. All payments under this Agreement are expressed in U.S. Dollars and will be paid in U.S. Dollars, by wire transfer or Automated Clearing House (ACH) payment to an account designated by Kymera (which account Kymera may update from time to time in writing).

11.7.2 Exchange. If any amounts that are relevant to the determination of amounts to be paid under this Agreement or any calculations to be performed under this Agreement are denoted in a currency other than U.S. Dollars, such amounts will be converted to their U.S. Dollar equivalent using Sanofi’s then-current standard procedures and methodology, including its then-current standard exchange rate methodology for the translation of foreign currency expenses into U.S. Dollars or, in the case of Sublicensees, such similar methodology, consistently applied. Calculation of Net Sales will exclude hedging and foreign exchange gain or loss realized through a hedging program.

11.7.3 Invoices. Except as otherwise set forth in this Agreement, Kymera will deliver an invoice to Sanofi for all payments owed by Sanofi to Kymera in accordance with Sanofi’s reasonable instructions. Sanofi will pay all undisputed payments owed to Kymera within [***] after receipt of the invoice for such owed amount, except where a different timeframe is expressly provided in another Section of this Agreement, and any disputed amounts owed by Sanofi will be paid within [***] of resolution of the Dispute.

11.8 Withholding Tax. Where any sum due to be paid to Kymera hereunder is subject to any withholding or similar tax, Sanofi will pay such withholding or similar tax to the appropriate Governmental Authority and deduct the amount paid from the amount then due to Kymera. Sanofi will timely transmit to Kymera an official tax certificate or other evidence of such withholding sufficient to enable Kymera to claim such payment of taxes. The Parties will cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, Milestone Payments, and other payments made by Sanofi to Kymera under this Agreement. Kymera will provide Sanofi any tax forms that may be reasonably necessary in order for Sanofi not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Laws, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax. Notwithstanding this

Section 11.8, if, as a result of a Withholding Action by Sanofi (including any assignee or successor), withholding is required by Applicable Law and the amount of such withholding exceeds the amount of withholding that would have been required if Sanofi had not committed the Withholding Action, then Sanofi shall pay an additional amount to Kymera such that, after withholding from the payment contemplated by this Agreement and such additional amount, Kymera receives the same amount as it would have received from Sanofi absent such Withholding Action by Sanofi. For the avoidance of doubt, if as a result of a Withholding Action by Kymera (including any assignee or successor) the amount of withholding under the law of the applicable jurisdiction exceeds the amount of such withholding that would have been required in the absence of such Withholding Action by Kymera, Sanofi shall be required to pay any additional amount only to the extent that Sanofi would be required to pay any additional amount to Kymera pursuant to the preceding sentence if Kymera had not committed such Withholding Action. For purposes of this Section 11.8, “Withholding Action” by a Party means (i) a permitted assignment or sublicense of this Agreement (in whole or in part) by such Party to an Affiliate or a Third Party outside of the United States; (ii) the exercise by such Party of its rights under this Agreement (in whole or in part) through an Affiliate or Third Party outside of the United States (or the direct exercise of such rights by an Affiliate of such Party outside of the United States); (iii) a redomiciliation of such Party, an assignee or a successor to a jurisdiction outside the United States; and (iv) any action by such Party that causes this Agreement or any payment contemplated by this Agreement to become subject to Tax in a jurisdiction outside of the United States or subject any payment contemplated by this Agreement to withholding in any jurisdiction that would not have been required absent such Withholding Action.

In addition, the Parties acknowledge and agree that, with regard to such Prosecution and Maintenance, and enforcement of the Patents under this Article 12, 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 Patents under this Article 12, including privilege under the common interest doctrine and similar or related doctrines.

12.8 Joint Research Agreements. The Parties intend that this Agreement is and will be understood to be a “joint research agreement” (as that term is defined in 35 U.S.C. § 100(h) and used in 35 U.S.C. § 102(c)), entered into for the purposes of researching, identifying and Developing Collaboration Compounds, Collaboration Candidates and Licensed Products. The Parties will coordinate their activities with respect to any submissions, filings or other activities in support thereof.

12.9 Patent Term Extension. On a Collaboration Target-by-Collaboration Target basis, following the Sanofi Participation Election Effective Date (if any) with respect to such Collaboration Target and solely with respect to [***], as between the Parties, Sanofi will be solely responsible for obtaining patent term restoration 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 Directed Against the applicable Collaboration Target. In exercising the foregoing responsibility with respect to a Collaboration Target following the Sanofi Participation Election Effective Date (if any) with respect to such Collaboration Target, Sanofi will determine which relevant [***] will be extended (including, without limitation, by filing supplementary protection certificates and any other extensions that are now or in the future become available). Kymera will abide by Sanofi’s determination and cooperate, as reasonably requested by Sanofi, in connection with the foregoing (including by providing appropriate information and executing appropriate documents), at Sanofi’s cost.

12.10 Recording. If Sanofi 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, Kymera will reasonably cooperate to execute and deliver to Sanofi any documents accurately reflecting or evidencing this Agreement that are necessary or desirable, in Sanofi’s reasonable judgment, to complete such registration or recordation. Sanofi will reimburse Kymera for all reasonable Out-of-Pocket Costs, including attorneys’ fees, incurred by Kymera in complying with the provisions of this Section 12.10.

12.11 Unitary Patent System. Sanofi will have the exclusive right to opt-in or opt-out of the EU Unitary Patent System for [***]. For clarity, “to opt-in or opt-out” refers to both the right to have or not 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 into the EU Unitary Patent System with respect to a given Patent, 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.

12.12 Trademarks. Following the Sanofi Participation Election Effective Date (if any) with respect to a Collaboration Target, Sanofi will have the sole and exclusive right, but not the obligation, to brand and promote the Licensed Products using trademarks, designs, copyrights, domain names, trade dress and trade names it determines appropriate in its sole discretion for the Licensed Products, which may vary within the Territory (each, a “Licensed Product Mark”). Sanofi will own all rights, title and interests in and to the Licensed Product Marks, and all goodwill in the Licensed Product Marks will inure to the benefit of Sanofi. Sanofi will have the sole and exclusive right and responsibility to register, maintain, defend and enforce the Licensed Product Marks to the extent it determines reasonably necessary. Except as otherwise agreed in writing by both Parties, Sanofi does not grant to Kymera, by implication, estoppel or otherwise, any license to any Licensed Product Mark. For the avoidance of doubt, trademarks, designs, trade dress and trade names evaluated for use as Licensed Products but not actually used in the Commercialization

112

of a Licensed Product will not be a Licensed Product Mark and will remain property of Sanofi after termination or expiration of this Agreement. In any event, any trademarks, service marks, names or logos that include any corporate name or logo of the Parties or their Affiliates will not be a Licensed Product Mark and will remain the property of each respective Party.

12.13 Falsified Medicines. Without limiting either Party’s rights or obligations under this Section 12.13:

12.13.1 Each Party will promptly notify the other Party in writing if it becomes aware of any Third Party’s manufacturing, sale, offer for sale, distribution or contribution to the manufacturing, shipment or commercialization of a medical product purporting to be a Licensed Product which deliberately or fraudulently misrepresents its identity, composition or source (“Falsified Medicine”); and

12.13.2 Sanofi will have the sole and exclusive right, but not the obligation, to lead any detection program, investigation or collaboration with any Governmental Authority and the sole and exclusive right, but not the obligation, to file or threaten to file a claim or lawsuit to enforce any rights against any Third Party manufacturing, selling, offering for sale or distributing Falsified Medicines or contributing to any of these actions. If requested by Sanofi, Kymera will reasonably cooperate with Sanofi with respect to any suspected Falsified Medicines to provide complementary information related to the applicable Licensed Product when necessary or requested by any Governmental Authority.

ARTICLE 14

INDEMNIFICATION; INSURANCE; LIMITATIONS

14.1 Indemnification.

14.1.1 Indemnification by Sanofi. Sanofi will indemnify, defend and hold harmless Kymera, its Affiliates, and its and its Affiliates’ employees, officers, directors and agents and their respective successors, heirs and assigns (each, a “Kymera Indemnified Party”) from and against any liability, loss, damage or expense (including reasonable attorneys’ fees and expenses) (collectively, “Liability”) arising out of any Third Party suit, investigation, claim or demand in connection with:

(a) the Research, Development, Manufacture, Commercialization or use of any Collaboration Compound, Collaboration Candidate or Licensed Product by, on behalf of, or under the authority of, Sanofi or any of its Affiliates (other than by a Kymera Indemnified Party);

(b) the breach by Sanofi of any of its representations, warranties or covenants set forth in this Agreement; or

(c) the negligence, recklessness or willful misconduct of Sanofi or any Sanofi Indemnified Party in connection with the performance of its obligations hereunder; and except, in each case ((a)–(c)), to the extent such claims fall within the scope of Kymera’s indemnification obligations under Section 14.1.2 (or would have had the Third Party claim been made against Sanofi under this Agreement) as to which Liability each Party will indemnify the other to the extent of their respective liability.

14.1.2 Indemnification by Kymera. Kymera will indemnify, defend and hold harmless Sanofi, its Affiliates and its and its Affiliates’ employees, officers, directors and agents and their respective successors, heirs and assigns (each, a “Sanofi Indemnified Party”) from and against any Liability arising out of any Third Party suit, investigation, claim or demand in connection with:

(a) the Research, Development, Manufacture or Commercialization of any Collaboration Compound, Collaboration Candidate or Licensed Product by, on behalf of, or under the authority of, Kymera or any of its Affiliates (other than by a Sanofi Indemnified Party);

(b) the breach by Kymera of any of its representations, warranties or covenants set forth in this Agreement;

(c) the negligence, recklessness or willful misconduct of Kymera or any Kymera Indemnified Party in connection with the performance of its obligations hereunder;

(d) [***]; or

(e) following the grant of the license set forth in Section 15.3.2(f)(i), the research, development, manufacture, and commercialization by or on behalf of Kymera or its Affiliates, sublicensees, subcontractors, agents or consultants of any (i) Terminated Product and (ii) Degrader that constitutes an improvement, modification or derivative of such Terminated Product,

120

in each case Covered by such license; and except, in each case ((a)–(c)), to the extent such claims fall within the scope of Sanofi’s indemnification obligations under Section 14.1.1 (or would have had the Third Party claim been made against Kymera under this Agreement) as to which Liability each Party will indemnify the other to the extent of their respective liability.

14.1.3 Procedure. Each Party will notify the other Party in writing if it becomes aware of a claim for which such Party may seek indemnification hereunder. If any Proceeding (including any governmental investigation) is instituted against a Party with respect to which indemnity may be sought pursuant to Section 14.1.1 or 14.1.2, as applicable, such Party (the “Indemnified Party”) will give prompt written notice of the indemnity claim to the other Party (the “Indemnifying Party”) and provide the Indemnifying Party with a copy of any complaint, summons or other written notice that the Indemnified Party receives in connection with any such claim. An Indemnified Party’s failure to deliver such written notice will relieve the Indemnifying Party of liability to the Indemnified Party under Section 14.1.1 or 14.1.2, as applicable, only to the extent such delay is prejudicial to the Indemnifying Party’s ability to defend such claim and allow the Indemnifying Party to assume the defense of claim. Provided that the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party will permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by negotiated settlement or otherwise (subject to this Section 14.1) and any failure to contest such obligation prior to assuming control will be deemed to be an admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim and will not settle or otherwise resolve such claim without the Indemnified Party’s prior written consent, which will not be unreasonably withheld, conditioned or delayed; provided that such consent will not be required with respect to any settlement involving only the payment of monetary awards for which the Indemnifying Party will be fully responsible. The Indemnified Party will cooperate with the Indemnifying Party in the Indemnifying Party’s defense of any claim for which indemnity is sought under this Agreement, at the Indemnifying Party’s cost and expense.

14.2 Insurance. Kymera and Sanofi will respectively, at their own cost and expense, obtain and maintain commercially reasonable insurance coverage from insurance carriers licensed to do business under the laws of the country, state, commonwealth, province, or territory in which such Party’s obligations are provided, with insurers that carry a rating of at least an A- VII or better from A.M. Best. Each Party will furnish to the other Party evidence of such insurance upon request. Notwithstanding the foregoing, Sanofi may self-insure to the extent that it self-insures other activities.

14.3 Limitation of Consequential Damages. Except for (a) claims of a Third Party that are subject to indemnification under this Article 14, (b) claims arising out of a Party’s fraud or willful misconduct or (c) a Party’s breach of Section 10.6, 10.7 or 10.8 or Article 16, neither Party nor any of its Affiliates will be liable to the other Party or its Affiliates for any incidental, special, punitive or other indirect damages or lost or imputed profits or royalties, lost data or cost of procurement of substitute goods or services, which are not probable and reasonably foreseeable, 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.

121

ARTICLE 15

TERM; TERMINATION

15.1 Term; Expiration. This Agreement is effective as of the Effective Date and, unless earlier terminated pursuant to the other provisions of this Article 15, will expire on the latest of (such period, the “Term”):

(a) on an Opt-In Product-by-Opt-In Product basis, the date on which neither Party is Developing or Commercializing such Opt-In Product in the U.S.;

(b) with respect to a Licensed Product that is not an Opt-In Product, on a country-by-country and Licensed Product-by-Licensed Product basis, on the date of expiration of all payment obligations under this Agreement with respect to such Licensed Product in such country; and

(c) in its entirety (i) upon the expiration of all payment obligations under this Agreement with respect to all Licensed Products in all countries pursuant to Article 11 or (ii) upon the termination of this Agreement with respect to all Collaboration Targets pursuant to clause (a) of Section 15.2.1.

15.2 Termination of the Agreement.

15.2.1 Automatic Termination of Collaboration Target. If Sanofi fails to timely exercise the Sanofi Participation Election Right with respect to a Collaboration Target in accordance with Section 4.5 prior to the applicable Sanofi Participation Election Deadline, this Agreement will automatically terminate with respect to such Collaboration Target, and, for clarity, such Collaboration Target will become a Terminated Target, with no further action by the Parties.

15.2.2 Sanofi’s Termination for Convenience. Sanofi may terminate this Agreement, either (i) in its entirety, or (ii) on a Collaboration Target-by-Collaboration Target basis, in each case ((i)-(ii)), for convenience by providing written notice of its intent to terminate to Kymera, in which case, such termination will be effective [***] after Kymera’s receipt of such written notice, and, for clarity, any such Collaboration Target, or each Collaboration Target to the extent this Agreement is terminated in its entirety, will become a Terminated Target.

15.2.3 Termination under Certain Circumstances.

(a) Sanofi’s Right to Terminate for Material Breach.

(i) Subject to Section 15.2.3(a)(ii) below, if Sanofi believes that Kymera is in material breach of this Agreement, Sanofi may deliver written notice of such material breach to Kymera. If the breach is curable, Kymera 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, which breach must be cured within [***] following its receipt of such written notice). If Kymera fails to cure, or fails to dispute, such breach within such [***] period or [***] period, as applicable, or the breach is not subject to cure, Sanofi may terminate this Agreement in its entirety or with respect to the particular Collaboration Target to which the breach relates by providing written notice to Kymera, in which case, this Agreement will terminate in its entirety or

with respect to such Collaboration Target, as applicable, on the date on which Kymera receives such written notice; provided, however, that if (A) the relevant breach is curable, but not reasonably curable within [***], and (B) Kymera is making a bona fide effort to cure such breach, Sanofi’s right to terminate this Agreement on account of such breach will be suspended for so long as Kymera is continuing to make such bona fide effort to cure such breach and if such breach is successfully cured, Sanofi will no longer have the right to terminate this Agreement on account of such breach.

(ii) If Sanofi believes that Kymera is in material breach of this Agreement and such breach constitutes a Step-In Trigger, as defined in Section 15.2.4, Sanofi may deliver written notice of such material breach to Kymera. If the breach is curable, Kymera will have [***] following its receipt of such written notice to cure such breach. If Kymera fails to cure, or fails to dispute, such breach within such [***] period, or the breach is not subject to cure, Sanofi may elect to exercise the alternate remedy provision set forth in Section 15.2.4. If Sanofi does not exercise the alternate remedy provision, this Agreement will terminate [***] after the date on which Kymera received written notice of the material breach.

(b) Sanofi’s Right to Terminate for Material Safety Event. If Sanofi provides to Kymera a Material Safety Event Notice pursuant to Section 7.6.2, Sanofi may include in such notice (or deliver at any time [***] thereafter) a written notice of termination (a “Safety Termination”), which termination notice will be effective as of the date of its issuance.

(c) Kymera’s Right to Terminate for Material Breach. If Kymera believes that Sanofi is in material breach of this Agreement, Kymera may deliver written notice of such material breach to Sanofi. If the breach is curable, Sanofi 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, which breach must be cured within [***] following its receipt of such written notice). If Sanofi fails to cure, or fails to dispute, such breach within such [***] period or [***] period, as applicable, or the breach is not subject to cure, Kymera may terminate this Agreement in its entirety or solely with respect to the particular Collaboration Target to which the breach relates, by providing written notice to Sanofi, in which case, this Agreement will terminate in its entirety or with respect to such Collaboration Target, as applicable, on the date on which Sanofi receives such written notice; provided, however, that if (A) the relevant breach (1) does not involve Sanofi’s failure to make a payment when due and (2) is curable, but not reasonably curable within [***], and (B) Sanofi is making a bona fide effort to cure such breach, Kymera’s right to terminate this Agreement on account of such breach will be suspended for so long as Sanofi is continuing to make such bona fide effort to cure such breach and if such breach is successfully cured, Kymera will no longer have the right to terminate this Agreement on account of such breach.

If a Party or its Affiliates (A) commences or actively and voluntarily participates in any legal action or administrative proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim of any Patent that is licensed to it by the other Party under this Agreement, or (B) actively and voluntarily assists, or directs or supports any other Person in bringing or prosecuting any legal action or administrative proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim of any Patent that is licensed to it by the other Party under this

123

Agreement (each of (A) and (B), a “Patent Challenge”), then, to the extent permitted by Applicable Law, the challenged Party will have the right, in its sole discretion, to terminate this Agreement with respect to any Collaboration Target to which such Patent relates, upon written notice to the challenging Party, [***] following such notice, and, unless the challenging Party withdraws or causes to be withdrawn all such challenge(s) (or in the case of ex-parte proceedings, multi-party proceedings, or other Patent Challenges that the challenging Party does not have the power to unilaterally withdraw or cause to be withdrawn, the challenging Party ceases assisting any other party to such Patent Challenge and, to the extent the challenging Party is a party to such Patent Challenge, it withdraws from such Patent Challenge within such [***] period), this Agreement will automatically terminate with respect to any Collaboration Target to which such Patent relates. Notwithstanding the foregoing, (a) the challenged Party will not have the right to terminate this Agreement under this Section 15.2.3(c) if the challenging Party challenges the validity of any Patents of the challenged Party licensed to such challenging Party under this Agreement in defense of claims of patent infringement filed by the challenged Party against such Party or its Affiliate, as the case may be, and (b) the termination provisions under this Section 15.2.3(d) will not apply with respect to any administrative proceeding that is filed, after consultation with the challenged Party, in a good-faith effort to correct, reinforce the patentability, validity or enforceability of, or expand the claim scope of, a challenged licensed Patent.

(ii) Notwithstanding the foregoing clause (i), in the event Kymera terminates this Agreement under this Section 15.2.3(e) with respect to a given Collaboration Target after completion of all Backup Research in accordance with Section 5.5, if [***], then for a period of [***] following the effective date of termination of this Agreement with respect to such Collaboration Target, Kymera will not, and will cause its Affiliates not to, [***]; provided, however, that the foregoing will not prohibit Kymera or its Affiliates from [***].

(iii) On a Collaboration Target by Collaboration Target basis, if (a) Kymera terminates this Agreement pursuant to Section 15.2.3(e)(i) with respect to such Collaboration Target, (b) the provisions of Section 15.2.3(e)(ii) apply, and (c) prior to the [***].

(iv) If either (Y) Sanofi does not provide a [***] within such [***] period, or (Z) [***], then, in each case ((Y) and (Z)), [***].

124

the “SAD Termination” and such terminated Second Additional Degraders, the “Terminated Degraders”), for convenience by providing written notice of its intent to terminate to Kymera, in which case, such termination will be effective (i) [***] after Kymera’s receipt of such written notice, if such notice is provided during the SAD Research Term, or (ii) [***] after Kymera’s receipt of such written notice, if such notice is provided after expiration of the SAD Research Term.

15.2.4 Remedy in Lieu of Termination. In the event that [***], in lieu of terminating this Agreement pursuant to Section 15.2.3(a), Sanofi may elect by written notice to Kymera, at Sanofi’s cost, to [***], in which case [***]. For clarity, [***]. In the event that Sanofi elects [***] pursuant to this Section 15.2.4, then [***].

15.2.5 Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in Section 15.2.3 disputes in good faith the existence, materiality, or failure to cure of any breach, and provides written notice to the Non-Breaching Party of such dispute within the relevant cure period, the Non-Breaching Party will not have the right to terminate this Agreement in accordance with Section 15.2.3, or the right to exercise the alternative remedy provision of Section 15.2.4, as applicable, unless and until the relevant dispute has been resolved pursuant to the dispute resolution provisions in Section 18.12. 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.

15.2.6 Termination for Insolvency. If, at any time during the Term, either Party 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”), the other Party may terminate this Agreement in its entirety by providing written notice of its intent to terminate this Agreement to such Party, in which case, this Agreement will terminate on the date on which such Party receives such written notice.

Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate Governmental Authority.

18.10 Governing Law. This Agreement, and all claims arising under or in connection therewith, will be governed by and interpreted in accordance with the substantive laws of The State of New York, without regard to conflict of law principles thereof.

18.12.1 Informal Dispute Resolution; Escalation to Executive Officers. In the event of any Dispute, the Parties will first attempt in good faith to resolve such Dispute by negotiation and consultation between themselves.

142

Dispute to the Executive Officers of the Parties by delivering written notice to the other Party, who will confer in good faith on the resolution of the issue for a [***] period following receipt of such written notice. If any Dispute is not resolved within such [***] period by the Executive Officers, each Party may, at its sole discretion, seek resolution of such Dispute in accordance with Section 18.12.2. Notwithstanding the foregoing, a matter that was subject to Section 9.9 will not also be subject to this Section but will otherwise be subject to Section 18.11 and all other provisions of this Section 18.12.

18.12.2 Jury Trial.

Each Party agrees that its unauthorized release of the other Party’s Confidential Information or its breach of Sections 10.6, 10.7 or 10.8 of this Agreement will cause irreparable damage to the other Party for which recovery of damages would be inadequate, and that such other Party will be entitled to obtain timely injunctive relief with respect to such breach, without the need to show irreparable harm or the inadequacy of monetary damages as a remedy, and without the requirement of having to post bond or other security, as well as any further relief that may be granted by a court of competent jurisdiction.

18.12.4 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 18.12 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. Further, with respect to any time periods that have run during the pendency of the Dispute, the applicable Party will have a reasonable period of time or any specific timeframe established by the tribunal’s decision to exercise any rights or perform any obligations affected by the running of such time periods.

18.12.5 Certain IP Disputes.
