(a)From time to time during the Research Term, Regeneron shall have the right to add additional NASH Targets as a “Reserved NASH Target,” or replace an existing Reserved NASH Target with an alternative NASH Target as a “Reserved NASH Target”, in each case in accordance with this Section 3.2.2(a). In the event that Regeneron desires to add a given NASH Target as a Reserved NASH Target, or replace a given Reserved NASH Target with an alternative NASH Target as a Reserved NASH Target, then Regeneron shall propose in writing to Alnylam that such Target be added as a Reserved NASH Target. Upon receipt of such notice by Alnylam, the list of Reserved NASH Targets shall automatically be deemed to be updated to include such new Target as a “Reserved NASH Target” if such Target satisfies the requirements of the definition of “NASH Target,” (provided that if the Parties fail to agree whether such Target satisfies the requirements of the definition of “NASH Target,” such matter shall be an “Expert Dispute” and resolved by the Expert in accordance with Schedule 1) and, if applicable, to remove any replaced NASH Target (as determined by Regeneron in its sole discretion), unless at the time of receipt of such notice from Regeneron, [***], in which case the Reserved NASH Target list shall not be updated to include such Target (provided that [***]). If Alnylam disagrees that a Target proposed by Regeneron pursuant to this Section 3.2.2(a) is a NASH Target, then Alnylam shall notify Regeneron thereof in writing within ten (10) Business Days after receipt of such proposal from Regeneron, and such dispute shall be submitted for resolution by an Expert in accordance with the process set forth in Section 2.2.3(a)(iv). Notwithstanding anything herein to the contrary, there shall be no more than [***] Reserved NASH Targets at any time.

(b)From time to time during the Research Term, Regeneron shall have the right to [***]. In the event that Regeneron desires to add a given Target as a Pre-Cleared Target, Regeneron may provide the identity of such Target to Alnylam’s independent Third Party gatekeeper for clearance by such Third Party gatekeeper in accordance with the gatekeeper process set forth in Section 3.2.3(a). Following completion of the Third Party gatekeeper process, Regeneron may, in its sole discretion, provide written notice to Alnylam with the identity of such Target (provided that such notice shall not include any Target that Alnylam’s Third Party gatekeeper identified as being prohibited (i.e., a “no”) from being included as a Pre-Cleared Target hereunder pursuant to Section 3.2.3(a)) to become a Pre-Cleared Target hereunder. Alnylam shall provide written notice to Regeneron within fifteen (15) Business Days of the date of delivery of such notice to Alnylam whether there are [***]. In the event that Alnylam provides such written notice to Regeneron, then Regeneron may, in its sole discretion, determine not to include such Target as a Pre-Cleared Target. In the event that Regeneron elects to add a given Target as a Pre-Cleared Target in accordance with this Section 3.2.2(b), then Schedule 1.197 shall automatically be deemed to include such Target as a Pre-Cleared Target.

(a)Gatekeeper Process. Either (i) in connection with Regeneron’s nomination of additional Pre-Cleared Targets in accordance with Section 3.2.2(b), or (ii) in preparation for the target selection process for new Collaboration Targets for a given Calendar Year during the Research Term, Regeneron may provide a list of Targets to Alnylam’s independent Third Party gatekeeper for clearance by such Third Party gatekeeper; provided that for the target selection process for new Collaboration Targets for a given Calendar Year during the Research Term, (A) such list shall not include more [***] for such Calendar Year; and (B) if any of the Targets submitted by Regeneron to the Third Party gatekeeper are designated as a “no” or “encumbered”, Regeneron may thereafter submit a reasonable number of additional Targets [***] for such Calendar Year to such Third Party gatekeeper for clearance. The Third Party gatekeeper shall confirm the availability of such Targets in accordance with Alnylam’s independent Third Party gatekeeping processes, which processes will be agreed to by the Parties and established within sixty (60) days after the Effective Date (provided that such agreed Third Party gatekeeping process shall comply with the Existing Alnylam Third Party Agreements). Such Third Party gatekeeper shall provide written notice to Regeneron of the existence of any conflict that would prohibit or limit inclusion of the applicable Target as a Pre-Cleared Target or Collaboration Target hereunder (on a “yes” or “no” or “encumbered” basis, if any, where “yes” means that the Target is not restricted in any way, “no” means the Target is prohibited from being added as a Pre-Cleared Target or Collaboration Target and “encumbered” means that the Target may be added as a Pre-Cleared Target or Collaboration Target, but a Third Party has certain rights to such Target, and in the event that the Target is designated as “encumbered” the Third Party gatekeeper shall describe the encumbrances to Regeneron in writing) solely as a result of, and in accordance with, those provisions of the applicable Existing Alnylam Third Party Agreements (as such provisions are expressly set forth on Schedule 9.2.15), which conflict notification will be provided to Regeneron within fifteen (15) Business Days of the date of delivery of Regeneron’s list to the Third Party gatekeeper. In the event that the Third Party gatekeeper reasonably determines that any Target on Regeneron’s list has such a conflict (i.e., either a “no” or “encumbrance”) and consequently may not be included (or may only be included subject to the described encumbrances) as a Pre-Cleared Target or Collaboration Target under this Agreement, the Co-Co Collaboration Agreement or the License Agreement, then Regeneron may, in its discretion, select a reasonable number of alternative Targets (that are either a CNS Target, Liver Target or Eye Target) in replacement of such rejected (or encumbered) Target and notify the Third Party gatekeeper thereof in writing with an update to Regeneron’s list of proposed Targets; provided that such replacement Targets shall again be subject to this Section 3.2.3(a). Alnylam shall notify the Third Party gatekeeper and Regeneron if any of the applicable provisions of the applicable Existing Alnylam Third Party Agreements (as such provisions are expressly set forth on Schedule 9.2.15) are no longer in force or effect. In the event that the Third Party gatekeeper had previously determined that any Target on Regeneron’s list had such a conflict and consequently could not be included (or could only be included with encumbrances, as applicable) as a Pre-Cleared Target or Collaboration Target under this Agreement, the Third Party gatekeeper shall promptly notify Regeneron in writing if such conflict (or encumbrance, as applicable) no longer exists. Notwithstanding the foregoing, this Section 3.2.3(a) shall not apply to any Target that is a Pre-Cleared Target as of the Execution Date, a Reserved Liver Target or a Reserved NASH Target.

(b)Annual Collaboration Target List and Collaboration Target Selection. During the fourth quarter of Calendar Year 2019 and during the fourth quarter of each Calendar Year thereafter during the Research Term, [***] such list shall not include any such Targets that Alnylam’s Third Party gatekeeper identified as being prohibited (i.e., a “no”) from being included as a Collaboration Target hereunder pursuant to Section 3.2.3(a)) to become Collaboration Targets in the next Calendar Year (each, an “Annual Collaboration Target List”), subject to the following:

(i)[***] may not select more than the Annual Target Maximum number of Targets for a given Calendar Year.

(ii)For the target selection processes occurring [***], the new Collaboration Targets shall include at least [***] CNS Targets and [***] Eye Targets (unless otherwise mutually agreed by the Parties); provided that [***] may decrease such numbers of CNS Targets or Eye Targets if it has a good faith scientific reason to modify the number of new Collaboration Targets to less than [***] CNS Targets or Eye Targets, as applicable, based on data generated by or on behalf of the Parties under this Agreement or any Co-Co Collaboration Agreement or License Agreement.

(iii)Alnylam shall provide written notice to Regeneron within fifteen (15) Business Days of the date of delivery of such list to Alnylam whether there are any Alnylam-Initiated GLP Tox Permitted Competing Products or Alnylam-Partnered Permitted Competing Products Directed to any of the Targets as permitted pursuant to the exceptions to exclusivity set forth in Section 5.7.1(a)(D), or a program for Competing Products Directed to any of the Targets as permitted pursuant to the exceptions to exclusivity set forth in Section 5.7.1(a)(B) or 5.7.1(a)(C), in each case, as of the date of Regeneron’s nomination of such Target, as if such Target were a Collaboration Target hereunder. In the event that Alnylam provides such written notice to Regeneron, then Regeneron may, in its sole discretion, select an alternative Target (that is either a CNS Target, Liver Target or Eye Target) in replacement of such Target; provided that such alternative Target shall again be subject to this Section 3.2.3(b).

(iv)If Regeneron selects and lists a Liver Target that is not a Reserved Liver Target, Reserved NASH Target or Regeneron Novel Liver Target, then Alnylam shall have the right, within thirty (30) days after Regeneron proposes such Liver Target in its written list, to object to such Liver Target, in Alnylam’s sole discretion, in which case such Liver Target shall not become a Collaboration Target for the next Calendar Year, and Regeneron may select an alternative Target (that is either a CNS Target, Liver Target or Eye Target) in replacement of such rejected Liver Target and notify Alnylam thereof in writing with an update to Regeneron’s list of Collaboration Targets; provided that if such replacement Target is a Liver Target, such replacement Target shall again be subject to this Section 3.2.3(b)(iv).

(v)If Alnylam desires to select a Target other than the Targets proposed by Regeneron to become Collaboration Targets for the next Calendar Year, then Alnylam may propose up to [***] alternative Targets (provided that for the target selection processes occurring [***] one such Target must be a CNS Target, unless otherwise agreed to by Regeneron in writing) in writing to Regeneron within fifteen (15) Business Days after receipt of the list of Targets from Regeneron under this Section 3.2.3(b) (provided that any such Target proposed by Alnylam must be either a Liver Target or CNS Target).

(A)For any Calendar Year, if Regeneron agrees with a given Target proposed by Alnylam, then [***] will determine [***] which Target from the list proposed by Regeneron as Collaboration Targets for the next Calendar Year will be replaced by such Target selected by Alnylam, and such final list of Targets shall be the Collaboration Targets for the next Calendar Year (provided that, for clarity, any such replaced Target shall not be a “Declined Target”).

(B)For any of the Targets proposed by Alnylam under this Section 3.2.3(b)(v) during the Target selection process in the fourth quarter of each of Calendar Years 2019, 2020 and 2021, the following shall apply: [***].

(C)For any of the Targets proposed by Alnylam under this Section 3.2.3(b)(v) during the target selection process [***], the following shall apply: If [***] shall be deemed to be a “Declined Target” for purposes of this Agreement.

(vi)Upon either Party’s request, the JSC shall convene an ad hoc meeting to discuss [***] Targets in accordance with Section 2.1.2(b).

(vii)If (1) Alnylam does not agree that a Target (other than a Reserved NASH Target) proposed by Regeneron satisfies the NASH Target definition, or (2) Alnylam does not agree that a Target proposed by Regeneron satisfies the definition of Regeneron Novel Liver Target, then, [***].

(viii)If a given nominated Target could fall within more than one category of Target (i.e., CNS Target, Eye Target or Liver Target), then the nominating Party will identify which category such Target will fall into for purposes of this Agreement (and any License Agreement or Co-Co Collaboration Agreement), as applicable, when such Target is nominated in accordance with this Section 3.2.3(b).

(c)Within twenty (20) days after the final list of Collaboration Targets for the next Calendar Year is determined pursuant to Section 3.2.3(b), (i) Alnylam shall provide to Regeneron a written list of (1) any additional Patent Rights Controlled by Alnylam (or its Affiliates) to be included within the “Alnylam Core Technology Patents” or the “Alnylam Product-Specific Patents”, as applicable, provided that, with respect to “Alnylam Core Technology Patents” only to the extent not previously listed on Schedule 1.16, and (2) any then existing Product-Related In-Licenses (to be set forth on Part 2 of Schedule 1.108) between Alnylam (or its Affiliates) and a Third Party in effect as of the date that the Target becomes a Collaboration Target hereunder, which shall thereafter be an “Existing Alnylam In-License” (and shall also provide to Regeneron a true, correct and complete copy of such agreements, subject to redaction as Alnylam’s outside counsel determines appropriate to comply with confidentiality obligations); in each case, with respect to such Collaboration Target, and (ii) Regeneron shall provide to Alnylam a written list of (1) any additional Patent Rights Controlled by Regeneron (or its Affiliates) to be included within the “Regeneron Product-Specific Patents”, and (2) any then existing Product-Related In-Licenses (to be set forth on Part 2 of Schedule 1.111) between Regeneron (or its Affiliates) and a Third

Party in effect as of the date that the Target becomes a Collaboration Target hereunder, which shall thereafter be an “Existing Regeneron In-License” (and shall also provide to Alnylam a true, correct and complete copy of such agreements, subject to redaction as Regeneron’s outside counsel determines appropriate to comply with confidentiality obligations); in each case, with respect to such Collaboration Target.

(d)At any time during the Research Term, but no more than [***], either Party may propose in writing to the other Party that a Target that is not already a Collaboration Target or Reserved NASH Target hereunder is or is not a NASH Target, as applicable; provided that Alnylam may only propose Targets pursuant to this Section 3.2.3(d) for which Alnylam has a good faith intention (itself or together with a Third Party) to commence an siRNA research program for such Target within the next twelve (12) months. Within thirty (30) days of receiving such request, the non-requesting Party may agree or object. Upon any such objection, the proposing Party, if it so elects, may elect to invoke the dispute resolution process set forth in Section 3.2.3(b)(vii) to make such determination. Upon any agreement by the Parties or resolution by the dispute resolution process set forth in Section 3.2.3(b)(vii), the JSC will record the applicable classification of the Target in its minutes; provided that, for clarity, either Party shall have the right to subsequently dispute the determination made pursuant to this Section 3.2.3(d) if new information becomes available with respect to such Target, and if a new determination is made, the JSC minutes will be updated to reflect such new determination.

(e)At any time during the Term, either Party may propose in writing to the other Party that [***] or other delivery technology is or is not a type of [***] Delivery Technology, Other Delivery Technology, Non-CNS/Eye Delivery Technology or Non-Liver Delivery Technology, as measured by [***]. Within thirty (30) days of receiving such request, together with reasonable supporting data from the requesting Party, if any, the non-requesting Party may agree or object. Upon any such objection, the proposing Party, if it so elects, may elect to invoke the dispute resolution process set forth in Section 3.2.3(b)(vii) to determine if a targeting ligand or other delivery technology is or is not a type of [***] Delivery Technology, Other Delivery Technology, Non-CNS/Eye Delivery Technology or Non-Liver Delivery Technology. Upon any agreement by the Parties or resolution by the dispute resolution process set forth in Section 3.2.3(b)(vii), the JSC will record the applicable classification of the [***] or other delivery technology in its minutes; provided that, for clarity, either Party shall have the right to subsequently dispute the determination made pursuant to this Section 3.2.3(e) if new information becomes available with respect to such [***] or other delivery technology (other than GalNAc, which shall remain classified as Non-CNS/Eye Delivery Technology in all cases), and if a new determination is made, the JSC minutes will be updated to reflect such new determination.

(a)For each Target selected pursuant to Section 3.2.3(b) to be a new Collaboration Target for a given Calendar Year, the Parties will initiate new Programs hereunder for each such Collaboration Target during such Calendar Year (provided that for Calendar Year 2019, the Parties shall initiate each of the Initial Programs as set forth in Section 3.2.1), and the Parties shall prepare, in accordance with Section 3.4.1, the initial Candidate Discovery Plan for each such new Program.

(b)With respect to each Target that is added as a new “Collaboration Target” pursuant to Section 3.2.3(b), (i) the Program for such new Collaboration Target shall be a “New Program” hereunder, (ii) the Patent Rights designated as “Alnylam Core Technology Patents” or “Alnylam Product-Specific Patents”, respectively, pursuant to Section 3.2.3(c) shall be part of the “Alnylam Core Technology Patents” or “Alnylam Product-Specific Patents”, respectively, for such New Program, (iii) the Patent Rights designated as “Regeneron Product-Specific Patents” pursuant to Section 3.2.3(c) shall be part of the Regeneron Product-Specific Patents for such New Program, (iv) the agreements designated as “Existing Alnylam In-Licenses” pursuant to Section 3.2.3(c) shall be “Existing Alnylam In-Licenses” for such New Program, and (v) the agreements designated as “Existing Regeneron In-Licenses” pursuant to Section 3.2.3(c) shall be “Existing Regeneron In-Licenses” for such New Program.

3.3Research Term; Research Term Extension; Research Term Tail; Discontinuance of Programs.

3.3.1Research Term. The Parties agree and acknowledge that new Collaboration Targets will only be chosen during the Research Term; provided that, for the avoidance of doubt, if a given Collaboration Target was chosen during the Research Term, then the Program for such Collaboration Target shall continue hereunder following the Research Term during the Research Term Tail (even if activities under such Program were not commenced during the Research Term), subject to Section 3.3.3.

3.3.2Research Term Extension by Regeneron. Regeneron shall have the right, in its sole discretion, to extend the Research Term for the Research Term Extension Period (the “Research Extension Option”) by providing Alnylam with written notice of such election no later than [***] and thereafter paying Alnylam the Research Extension Fee within sixty (60) days after delivery of such notice.

(a)The Parties shall conduct, or continue to conduct, as applicable, Development activities under each Program for any Collaboration Targets that were chosen as of the end of the Research Term (even if activities under such Program were not commenced during the Research Term) through the end of the Research Term Tail for the applicable Program in accordance with this Agreement, with the goal of identifying Lead Candidates under each such Program prior to the end of the Research Term Tail. For clarity, during the Research Term Tail for a given Program, Alnylam and its Affiliates shall have no obligation to initiate the synthesis of a Collaboration Product under such Program if [***].

(b)With respect to any Program for [***] then within thirty (30) days after the end of the Research Term Tail, each Party shall deliver to the other Party its Program Data Package for such [***] (provided that, with respect to any Eye Program, Regeneron’s Program Data Package delivered to Alnylam shall only include the information contained in parts (c) and (d) of the definition of “Program Data Package”). For each [***] that is an Eye Program, Regeneron shall have the right, in its sole discretion, to elect to enter into a License Agreement for such Eye Program with Regeneron as the “Licensee” thereunder (which election may be made by

Regeneron on a [***] basis), by providing written notice of such election to Alnylam within [***] days after receipt of the applicable Program Data Packages (the “Research Term Tail Election Period”). If Regeneron makes its election to enter into a License Agreement for any such Eye Program during the Research Term Tail Election Period for the applicable Program, then the Parties, subject to Section 4.9, shall enter into a License Agreement with respect to such Eye Program (and the Collaboration Target and Collaboration Products thereunder), including completing the exhibits and schedules thereto, with Regeneron as the “Licensee” under such License Agreement (and, subject to Section 4.9, pending such time as the License Agreement is entered into for such Program, Alnylam shall, and hereby does, grant to Regeneron the licenses as set forth in the License Agreement with respect to such Eye Program (including the Collaboration Target and Collaboration Products thereunder)). For the avoidance of doubt, the provisions of Sections 4.5 and 4.7 shall apply with respect to any such License Agreement. For each [***] that is a CNS Program or Liver Program, the Parties shall have the right, on an alternating basis (with Regeneron having the first right to pick any such [***] for which to enter into a License Agreement as the “Licensee”, and Alnylam having the second right to pick any such [***] for which to enter into a License Agreement as the “Licensee”, and so on, provided that if either Regeneron or Alnylam, as applicable, does not choose to pick any of the remaining [***] for which to enter into a License Agreement as the “Licensee” on one of its turns, then the other Party shall have thereafter have the sole right to pick any one or more of the remaining [***] that are CNS Programs or Liver Programs for which to enter into a License Agreement as the “Licensee”), to elect to enter into a License Agreement for such [***] with such Party as the “Licensee” thereunder by providing written notice of such election to the other Party during the Research Term Tail Election Period and complying with the terms and conditions of this Section 3.3.3(b) (mutatis mutandis); provided that, solely with respect to those [***] for which the Parties enter into a License Agreement with Alnylam as the “Licensee”, Regeneron shall pay to Alnylam the Lead Candidate Payment for each such [***] within thirty (30) days after the date that the first Lead Candidate is designated (consistent with the Lead Candidate Criteria set forth in the applicable Candidate Discovery Plan prior to the termination of such Candidate Discovery Plan) under such [***] under such License Agreement and the JSC (under the applicable License Agreement) is notified of such designation (and, for clarity, with respect to any [***] for which the Parties entered into a License Agreement with Regeneron as the “Licensee”, Regeneron shall not be required to make any Lead Candidate Payments). If a Party does not make its election to enter into the License Agreement for a given Program during the Research Term Tail Election Period as set forth in this Section 3.3.3(b), then such Program shall be deemed to be a “Terminated Program” and the Collaboration Target under such Terminated Program, a “Terminated Target”.

(a)With respect to the Initial Collaboration Targets, (i) no later than sixty (60) days after the Effective Date, for at least [***] such Initial Collaboration Targets and (ii) promptly thereafter for the remaining Initial Collaboration Targets, the Parties shall prepare and provide the JSC with a proposed Candidate Discovery Plan (including the Lead Candidate Criteria) for each such Initial Collaboration Target for the JSC’s review, discussion and approval.

(b)With respect to each Collaboration Target (other than the Initial Collaboration Targets), within thirty (30) days after the beginning of the Calendar Year for which such Target was added as a new Collaboration Target hereunder, the Parties shall prepare and provide the JSC with a proposed Candidate Discovery Plan (including the Lead Candidate Criteria) for each such new Collaboration Target for the JSC’s review, discussion and approval.

(c)During the preparation of the Candidate Discovery Plan for a given Collaboration Target that is a CNS Target or an Eye Target, the Parties shall discuss the inclusion of the research of [***].

(d)The JSC shall endeavor to approve the Candidate Discovery Plan within thirty (30) days after receipt of the proposed Candidate Discovery Plan; provided, that the Candidate Discovery Plan shall not become effective unless and until approved by the JSC (or the Executive Officers pursuant to Section 2.2.3(a) or the Lead Party pursuant to Section 2.2.3(a)(i)); provided further that the Lead Candidate Criteria must be approved by the JSC by consensus or the Executive Officers or the Expert (or, with respect to an Eye Program, the Lead Party pursuant to Section 2.2.3(a) (i.e., without the Lead Party exercising its final decision-making authority, other than with respect to an Eye Program)). Following approval of the Candidate Discovery Plan for a given Program, the JSC will review such Candidate Discovery Plan annually and discuss, propose and approve updates and material amendments thereto; provided that no update or material amendment to a given Candidate Discovery Plan shall be effective unless and until approved by the JSC (or the Executive Officers pursuant to Section 2.2.3(a) or the Lead Party pursuant to Section 2.2.3(a)(i)).

(e)Each Party shall use Commercially Reasonable Efforts to (i) perform the Development activities assigned to it under the Candidate Discovery Plan in accordance with the timeline set forth therein and (ii) achieve the goals and objectives set forth in the Candidate Discovery Plan.

(f)Prior to designation of the first Lead Candidate from a given Program, if either Party determines in good faith that the Program for such Collaboration Target is not reasonably likely to result in a Collaboration Product that satisfies the Lead Candidate Criteria for such Collaboration Target, then such Party shall notify the other Party through the JSC of such determination. In such case, the JSC (or the Executive Officers pursuant to Section 2.2.3(a) or the Lead Party pursuant to Section 2.2.3(a)(i)) may determine to discontinue such Program. In the event that the JSC (or the Executive Officers pursuant to Section 2.2.3(a) or the Lead Party pursuant to Section 2.2.3(a)(i)) determines to discontinue any such Program, then such Program shall be deemed to be a “Terminated Program” and the Collaboration Target under such a “Terminated Target”, and the Parties shall promptly wind-down, in compliance with Applicable Law, all Development activities under such Program. In the event that one or more Programs become Terminated Programs during a given Calendar Year, then [***]. In addition, in the event that a given Program becomes a “Terminated Program” pursuant to this Section 3.4.1(f) as a result of Regeneron exercising its Lead Party decision-making right pursuant to Section 2.2.3(a)(i) after the first dosing of the first non-human primate with Collaboration Product in the pilot non-human primate study under such Program (but before a Lead Candidate is designated from such Program), then Regeneron shall pay to Alnylam the Lead Candidate Payment for such Program within thirty (30) days after such Program becomes a “Terminated Program” pursuant to this Section 3.4.1(f).

(g)As part of the activities under a given Program, in order to identify a Lead Candidate for such Program, Alnylam shall generate and Develop new siRNAs Directed to the Collaboration Target under such Program, and shall also contribute and Develop siRNAs Directed to the Collaboration Target under such Program that are otherwise controlled by Alnylam or its Affiliates (provided that, for clarity, [***]). Without limiting the foregoing, for a given Collaboration Target, in the event that [***].

3.4.2Operational Discretion. Subject to the terms and conditions of this Agreement, the Party to which an activity under any Candidate Discovery Plan is assigned shall have the right to make operational decisions with respect to how such activity is conducted from an operational perspective; provided that (a) such decisions are consistent with this Agreement and the Candidate Discovery Plan and (b) such decisions are consistent with customary business practices for other of its similar products.

3.4.3Continuation of Activities. For the avoidance of doubt, with respect to a given Program, if any activities under the Candidate Discovery Plan have not been completed prior to entering into a Co-Co Collaboration Agreement or License Agreement, as applicable, for such Program, then such activities shall continue to be conducted under a Co-Co Collaboration Agreement or License Agreement; provided that until such time as a Co-Co Collaboration Agreement or License Agreement is entered into, the Parties shall continue to perform the activities under the Candidate Discovery Plan hereunder even if a Lead Candidate has already been identified.

3.4.4Assistance. For so long as a given Program is being conducted hereunder, promptly after request by a Party, the non-requesting Party shall (and shall cause its Affiliates to) cooperate with the requesting Party and provide reasonable assistance to the requesting Party to enable the requesting Party (and its Affiliates) to conduct its Development activities under such Program in accordance with the applicable Candidate Discovery Plan for such Program, as reasonably requested by the requesting Party, including providing the requesting Party (and its designees) with reasonable access by teleconference or in-person (as requested by the requesting Party) to then-employed personnel of the non-requesting Party (and personnel of its Affiliates) to assist with the transition and answer questions related to Collaboration Products or the Development thereof pursuant to this Agreement in accordance with the applicable Candidate Discovery Plan for such Program.

3.4.5Subcontracting. Each Party shall have the right to subcontract any of its Development activities under this Agreement to a Third Party (a “Third Party Provider”) without the other Party’s consent (provided that Alnylam shall not subcontract any activities allocated to Alnylam under a Candidate Discovery Plan without Regeneron’s prior consent, such consent not to be unreasonably withheld, conditioned or delayed, except that Alnylam may subcontract those activities set forth on Schedule 3.4.5 to those Third Party Providers as set forth on such schedule to the extent Alnylam subcontracts such activities in the ordinary course of Alnylam’s business, which schedule may be updated from time to time by the JSC to include additional Third Party Providers upon Alnylam’s reasonable request and Regeneron’s consent, not to be unreasonably

withheld, conditioned or delayed); provided that any subcontract entered into by a Party pursuant to this Section 3.4.5 must (a) be in writing, (b) be consistent with the terms and conditions of this Agreement, including containing confidentiality provisions at least as protective as those contained in ARTICLE 8, and (c) provide the other Party with the same rights with respect to any intellectual property arising from the subcontracted activities as it would have if the subcontracting Party performed such activities under this Agreement (except that with respect to any subcontract entered into with a Third Party contract manufacturer, such Third Party may retain ownership of any general manufacturing process improvement of general application; provided that such Third Party grants the subcontracting Party a sublicenseable license with respect to any such improvement to the extent related to a Collaboration Product). In the event the subcontracting Party seeks to subcontract with an academic, governmental, not-for-profit or public institution and is unable to comply with subsection (c) above, then the subcontracting Party may submit a written request to the other Party for its consent to such subcontract through the Alliance Managers. If the other Party fails to respond to such request within three (3) weeks after receipt of such written request, such request shall be deemed to have been approved, and the subcontracting Party may proceed with the subcontract. The subcontracting Party shall (x) oversee the performance by its subcontractors of the activities subcontracted pursuant to this Section 3.4.5 in a manner that would be reasonably expected to result in their timely and successful completion and (y) be responsible and liable for the actions and omissions of its subcontractors. No subcontracting pursuant to this Section 3.4.5 shall relieve the subcontracting Party of any of its obligations, or the other Party of any of its rights, under this Agreement.

3.4.6Compliance. Each Party shall perform or cause to be performed any and all of its Development activities, including its activities under each applicable Candidate Discovery Plan, in a good scientific manner and in compliance with all Applicable Law.

3.6Information Exchange. As long as a Party is conducting Development activities under this Agreement, including under a Candidate Discovery Plan, upon the reasonable request of such Party (the “Requesting Party”), the non-Requesting Party shall provide to the Requesting Party Information that is licensed to the other Party under this Agreement to the extent that it is necessary or reasonably useful for the Requesting Party to perform its Development activities under any Candidate Discovery Plan, or, with respect to the Lead Party as the Requesting Party, for Developing any Collaboration Product or for filing, obtaining or maintaining INDs or Regulatory Approval for any Collaboration Product, including copies of all material scientific information and data related to such Collaboration Product.

3.7.1Each of Alnylam and Regeneron shall, and shall ensure that its Third Party Providers, maintain complete, current and accurate records of all of its Development activities under this Agreement, including under each Candidate Discovery Plan, and all data and other information resulting from such Development activities, which records shall (a) be in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes, and in compliance with Applicable Law, (b) properly reflect all work done and results achieved in the

performance of such Development activities, and (c) record only such Development activities and shall not include or be commingled with records of activities that are not conducted under this Agreement. On a Program-by-Program basis, Alnylam or Regeneron, as the case may be, shall retain, or cause to the retained, such records for at least three (3) years after the termination of this Agreement (in its entirety) or termination of the applicable Program, whichever is earlier, or for such longer period as may be required by Applicable Law.

3.7.2For each given Program, each Party shall promptly provide to the JSC a summary of material non-clinical data with respect to any Development activities under each Candidate Discovery Plan for such Program, and, upon the reasonable request by the other Party, shall provide the other Party copies of or access to all non-clinical data, and other material Information, results, and analyses with respect to such Development activities for such Program (collectively, “Development Data”). In addition, upon the reasonable request of a Party, the other Party shall provide to the requesting Party any material Development Data for such Program that has not been previously provided by such other Party to the JSC pursuant to this Section 3.7.2.

3.7.3Notwithstanding anything to the contrary contained herein, neither Party shall be required to provide to, or otherwise share with, the other Party any data (including Development Data and CMC information) specific to such Party’s Proprietary Unlicensed Component, unless otherwise required by a Regulatory Authority.

3.8Material Transfer. In the event a Party transfers to the other Party any Materials under this Agreement, the receiving Party shall: (a) use such Materials solely for the purpose of exercising its rights or fulfilling its obligations under this Agreement (or under a License Agreement or Co-Co Collaboration Agreement, as applicable) and for no other purpose; and (b) not transfer such Materials to any Third Party without the providing Party’s prior written consent, provided that the receiving Party shall have the right to transfer such Materials to its Sublicensees or subcontractors solely to the extent for such Third Party to conduct the activities on behalf of, or as a Sublicensee of, such receiving Party in furtherance of this Agreement (or a License Agreement or Co-Co Collaboration Agreement, as applicable). In the event the Parties anticipate the transfer of any patient samples or patient information, the Parties shall negotiate in good faith and enter into an agreement governing such transfer and subsequent use, in compliance with all Applicable Law.

4.1Delivery of Program Data Package. On a Program-by-Program basis, within thirty (30) days after a Party reasonably believes that one or more Collaboration Products satisfies the Lead Candidate Criteria and notifies the other Party thereof in writing, each Party shall provide to the other Party its Program Data Package for such Program (provided that, with respect to any Eye Program, Regeneron’s Program Data Package delivered to Alnylam shall only include the information contained in parts (c) and (d) of the definition of “Program Data Package”). For purposes of this Agreement, the “Data Package Delivery Date” for a given Program shall be the date on which the applicable Program Data Packages are delivered for such Program pursuant to this Section 4.1 (or, if elected by a Party, such date as the other Party was supposed to deliver its Program Data Package for such Program pursuant to this Section 4.1, if such Program Data Package was not timely delivered by such other Party).

4.2Selection of a Lead Candidate. On a Program-by-Program basis, within fifteen (15) Business Days after the Data Package Delivery Date for such Program, the JSC will meet and review such Program Data Packages for such Program. The JSC will determine whether any of the Collaboration Products for such Program satisfies the Lead Candidate Criteria, in which case the JSC shall designate such Collaboration Product(s) as a Lead Candidate for such Program (unless otherwise mutually agreed by the Parties). If the JSC does not believe that any Collaboration Products for such Program satisfies the Lead Candidate Criteria, then the Parties shall continue to conduct additional Development activities with respect to such Program in accordance with the Candidate Discovery Plan (as may be amended in accordance with this Agreement), and thereafter resubmit Program Data Packages as and to the extent applicable in accordance with Section 4.1. In the event that the JSC does not agree on whether any Collaboration Product satisfies the Lead Candidate Criteria for a given Program, then such dispute will be resolved in accordance with Section 2.2.3(a)(iv). Notwithstanding the foregoing, the Parties may mutually agree (or, with respect to an Eye Program, Regeneron may determine) that a Collaboration Product for such Program will progress to IND-enabling studies even if such Collaboration Product does not otherwise satisfy the Lead Candidate Criteria, and, in such case, such Collaboration Product will be deemed to be a “Lead Candidate” for such Program. Any designation of a Collaboration Product as a Lead Candidate for a given Program by the JSC or by the Expert in accordance with Section 2.2.3(a)(iv), or by mutual agreement of the Parties (or, with respect to an Eye Program, by Regeneron) pursuant to the preceding sentence, shall be recorded in the minutes of the JSC, and the date on which such Lead Candidate is so designated by the JSC or the Expert or mutually by the Parties (as applicable) shall be the “Lead Candidate Date”.

4.3.1Lead Continuation Party. Regeneron shall be the Lead Continuation Party for each Eye Program (and Regeneron shall be deemed to be designated as the “Lead Continuation Party” for a given Eye Program as of the Lead Candidate Date for such Eye Program).

4.3.2Regeneron License Agreements. Except as set forth in Section 5.7.1(a)(C)(b), on an Eye Program-by-Eye Program basis, within twenty (20) Business Days after designation of Regeneron as the Lead Continuation Party for a given Eye Program pursuant to Section 4.3.1, the Parties shall enter into a License Agreement with respect to such Eye Program (and the Collaboration Target and Collaboration Products thereunder), including completing the exhibits and schedules thereto, with Regeneron as the “Licensee” under such License Agreement. Notwithstanding the foregoing, if Regeneron, in its sole discretion, notifies Alnylam in writing within twenty (20) Business Days after such designation of Regeneron as the Lead Continuation Party for such Eye Program that Regeneron does not wish to enter into a License Agreement for such Eye Program with Regeneron as the “Licensee” thereunder (such notice for a given Eye Program, a “Regeneron Eye Program Discontinuation Notice”), then (a) the Parties shall not enter into such License Agreement for such Eye Program, (b) the Eye Program shall be deemed to be a “Terminated Program” (and not a Licensed Program) and (c) the Collaboration Target under such Eye Program shall be deemed to be a “Terminated Target”. Unless Regeneron has provided a Regeneron Eye Program Discontinuation Notice for a given Eye Program, subject to Section 4.9, effective as of the Lead Candidate Date and pending such time as the License Agreement is entered into for such Eye Program, Alnylam shall, and hereby does, grant to Regeneron the licenses as set forth in the License Agreement with respect to such Eye Program (including the Collaboration Target and Collaboration Products thereunder).

If the non-Lead Continuation Party does not deliver the Collaboration Election Notice for a given Liver Program or CNS Program, as applicable, then the provisions of Section 4.4.4 shall apply for such Program.

4.4.3License Agreement for Non-Lead Continuation Party. On a Liver Program-by-Liver Program or CNS Program-by-CNS Program basis, as applicable, if the non-Lead Continuation Party delivers a Collaboration Election Notice for a given Liver Program or CNS Program, as applicable, pursuant to Section 4.4.2, but the Lead Continuation Party thereafter notifies the non-Lead Continuation Party in writing in accordance with Section 4.4.2 that it does not desire to enter into a Co-Co Collaboration Agreement for such Program, then within ten (10) Business Days after such notice from the Lead Continuation Party, the Parties shall enter into a License Agreement with respect to such Program (and the Collaboration Target and Collaboration Products thereunder), including completing the exhibits and schedules thereto, with the non-Lead Continuation Party as the “Licensee” under such License Agreement. Subject to Section 4.9, effective as of the date the Lead Continuation Party notifies the non-Lead Continuation Party in writing in accordance with Section 4.4.2 that it does not desire to enter into a Co-Co Collaboration Agreement for such Liver Program or CNS Program, as applicable, and pending such time as the License Agreement is entered into for such Liver Program or CNS Program, as applicable, the Lead Continuation Party shall, and hereby does, grant to the non-Lead Continuation Party the licenses as set forth in the License Agreement with respect to such Liver Program or CNS Program, as applicable (including the Collaboration Target and Collaboration Products thereunder). Notwithstanding the foregoing, if the non-Lead Continuation Party, in its sole discretion, notifies the other Party in writing within ten (10) Business Days after the non-Lead Continuation Party first has the right to enter into a License Agreement for such Program pursuant to this Section 4.4.3, that such non-Lead Continuation Party does not wish to enter into a License Agreement and be the “Licensee” thereunder for such Liver Program or CNS Program, as applicable, then (a) the Parties shall not enter into such License Agreement for such Liver Program or CNS Program, as applicable, with the non-Lead Continuation Party as the “Licensee” thereunder (and the license grant to such non-Lead Continuation Party set forth in this Section 4.4.3 shall not apply), and (b) (i) such Liver Program or CNS Program, as applicable, shall be deemed to be a “Terminated Program” and (ii) the Collaboration Target under such Program shall be deemed to be a “Terminated Target”.

4.4.4License Agreement for Lead Continuation Party. On a Liver Program-by-Liver Program or CNS Program-by-CNS Program basis, as applicable, if the non-Lead Continuation Party does not deliver a Collaboration Election Notice for a given Liver Program or CNS Program, as applicable, pursuant to Section 4.4.2, then within twenty (20) Business Days after the end of the Collaboration Election Period for such Program, the Parties shall enter into a License Agreement with respect to such Program (and the Collaboration Target and Collaboration Products thereunder), including completing the exhibits and schedules thereto, with the Lead Continuation Party as the “Licensee” under such License Agreement. Subject to Section 4.9, effective as of the end of the Collaboration Election Period for a given Liver Program or CNS Program, as applicable, pursuant to Section 4.4.2, and pending such time as the License Agreement is entered into for such Liver Program or CNS Program, as applicable, the non-Lead Continuation Party shall, and hereby does, grant to the Lead Continuation Party the licenses as set forth in the License Agreement with respect to such Liver Program or CNS Program, as applicable (including the Collaboration Target and Collaboration Products thereunder).

The Parties agree and acknowledge that the form of License Agreement and Co-Co Collaboration Agreement are attached as exhibits to this Agreement. If the Parties are to enter into a License Agreement or Co-Co Collaboration Agreement, as applicable, with respect to a given Program pursuant to Section 4.3 or Section 4.4, as applicable, the Parties will execute such License Agreement or Co-Co Collaboration Agreement for the applicable Program (including the Collaboration Target and Collaboration Products thereunder), which shall consist of mechanically inserting the relevant schedules and exhibits, completing the applicable blank provisions, and deleting bracketed provisions that are not applicable in the form of License Agreement or form of Co-Co Collaboration Agreement, in each case, in accordance with the footnotes in such form agreements to the extent applicable. For clarity, a License Agreement or Co-Co Collaboration Agreement, as applicable, with respect to a given Program will not contain any additional provisions, subject to Section 13.7.2 of the applicable Co-Co Collaboration Agreement or Section 13.7.2 of the applicable License Agreement.

4.6.1On a Program-by-Program basis, commencing on the date of selection of each Initial Collaboration Target in accordance with Section 3.2.1 (or for the period commencing on the Execution Date until to the selection of the Initial Collaboration Targets, the Targets set forth on Schedule 3.2.1), or the date upon which a given Program for an additional Collaboration Target commences under this Agreement, as applicable, until the earlier of (a) such time as such Program becomes a Terminated Program hereunder or (b) such time as the Parties enter into a License Agreement or Co-Co Collaboration Agreement with respect to such Program, except as otherwise expressly permitted under this Agreement, and except as and to the extent set forth in the Existing Alnylam Third Party Agreements (as such agreements are existing as of the Effective Date), each Party shall not, and shall cause its Affiliates not to (x) assign, transfer, convey, encumber (through any liens, charges, security interests, mortgages, or similar actions) or dispose of, or enter into any agreement with any Third Party to assign, transfer, convey, encumber (through lien, charge, security interest, mortgage, or similar action) or dispose of, any Alnylam Patents, Alnylam Know-How, Regeneron Patents or Regeneron Know-How specifically related to such Program or any rights to any Collaboration Products under such Program (collectively, the “Program Assets”), except to the extent such assignment, transfer, conveyance, encumbrance or

disposition would not conflict with the rights or licenses granted to the other Party hereunder (or that would be granted to such other Party pursuant to a License Agreement or Co-Co Collaboration Agreement, if such License Agreement or Co-Co Collaboration Agreement were entered into with respect to such Program in accordance with this Agreement) or (y) license or grant to any Third Party, or agree to license or grant to any Third Party, any rights to any Program Assets if such license or grant would conflict with the rights or licenses granted to the other Party hereunder (or that would be granted to such other Party pursuant to a License Agreement or Co-Co Collaboration Agreement, if such License Agreement or Co-Co Collaboration Agreement were entered into with respect to such Program in accordance with this Agreement).

4.6.2Without limiting the provisions of Section 4.6.1, during the Research Term until such time as a given Target becomes a Collaboration Target under a Program hereunder (in which case the provisions of Section 4.6.1 shall apply), except as otherwise expressly permitted under this Agreement, and except as and to the extent set forth in the Existing Alnylam Third Party Agreements (as such agreements are existing as of the Effective Date), Alnylam shall not, and shall cause its Affiliates not to, (a) assign, transfer, convey, encumber (through any liens, charges, security interests, mortgages, or similar actions) or dispose of, or enter into any agreement with any Third Party to assign, transfer, convey, encumber (through lien, charge, security interest, mortgage, or similar action) or dispose of (i) any intellectual property specifically for (x) a given Eye Target (other than the Alnylam Reserved Target), CNS Target (other than the Alnylam Reserved Target), Reserved Liver Target, Reserved NASH Target or Pre-Cleared Target, as applicable, or (y) any siRNA Directed to any such Target as an Eye Product, CNS Product or Liver Product, as applicable, and that would otherwise be included in the Alnylam Patents or Alnylam Know-How if such Target were added as a Collaboration Target under this Agreement, or (ii) any rights specific to any product containing any such siRNA ((i) and (ii) collectively, the “Alnylam Field Related Assets”), except to the extent such assignment, transfer, conveyance, encumbrance or disposition would not conflict with the rights or licenses granted to Regeneron hereunder (or that would be granted to Regeneron pursuant to a License Agreement or Co-Co Collaboration Agreement, if such License Agreement or Co-Co Collaboration Agreement were entered into with respect to such Target) if such Target were added as a Collaboration Target hereunder (but with respect to requirements to obtain Control of certain Alnylam Product-Specific Patents, taking into account Section 7.1.5(a)) or (b) license or grant to any Third Party, or agree to license or grant to any Third Party, any rights to any Alnylam Field Related Assets if such license or grant would conflict with the rights or licenses granted to Regeneron hereunder (or that would be granted to Regeneron pursuant to a License Agreement or Co-Co Collaboration Agreement, if such License Agreement or Co-Co Collaboration Agreement were entered into with respect to such Target) if such Target were added as a Collaboration Target hereunder (but with respect to requirements to obtain Control of certain Alnylam Product-Specific Patents, taking into account Section 7.1.5(a)), provided that this Section 4.6.2 shall not apply to the prosecution or maintenance (including preparation, submission and withdrawal) of any Patent Rights by Alnylam or any of its Affiliates in the ordinary course.

4.7License Agreements and Co-Co Collaboration Agreements. Notwithstanding anything to the contrary contained herein, on a Program-by-Program basis, upon execution of a License Agreement or Co-Co Collaboration Agreement, as applicable, for such Program, the further Development, Manufacture and Commercialization of Collaboration Products Directed to the applicable Collaboration Target shall be governed by the License Agreement or Co-Co Collaboration Agreement, as applicable; but without prejudice to any rights that shall have accrued (or that may accrue as a result of activities under this Agreement) to the benefit of a Party with respect to such Program hereunder prior to entering into such License Agreement or Co-Co Collaboration Agreement.

4.8.1The Parties shall negotiate in good faith to enter into an agreement governing the C5 Product (the “C5 Collaboration Agreement”) and an agreement governing the C5 Combination Product (the “C5 Combination License Agreement,” and together with the C5 Collaboration Agreement, the “C5 Agreements”) in accordance with the C5 Agreements Term Sheet following the Effective Date and in accordance with the timelines described in this Section 4.8. Within [***] Business Days after the Effective Date, Regeneron shall deliver an initial draft of the C5 Combination License Agreement, and within [***] after the Effective Date, Regeneron shall deliver an initial draft of the C5 Collaboration Agreement. Within [***] of its receipt of such initial drafts, Alnylam shall provide a counterproposal, if any, for such C5 Agreements, and thereafter the Parties shall use good faith efforts, including through good faith negotiations, to finalize such C5 Agreements prior to [***] of the Effective Date.

4.8.2In the event that the Parties cannot negotiate and finalize the C5 Agreements on or prior to [***] of the Effective Date (or such longer time period as may be mutually agreed by the Parties), and provided that both Parties have been negotiating in good faith and in accordance with this Agreement, then either Party may, by written notice to the other Party, initiate the procedures described in this Section 4.8 to finalize the definitive terms and conditions of such agreement through binding arbitration as follows:

(a)Within [***] of such written notice, each Party will (i) prepare drafts of the proposed C5 Agreements to be used in such arbitration proceeding (each, an “Arbitration Draft” and collectively, the “Arbitration Drafts”) and (ii) submit its respective Arbitration Drafts to the other Party, and the Parties shall, within [***] after exchanging the Arbitration Drafts, meet to determine whether they agree to enter into either Party’s Arbitration Drafts or modified versions thereof.

(b)If the Parties are unable to so agree within [***] after the Parties meet pursuant to Section 4.8.2(a), then the Parties shall mutually select a neutral professional in business or licensing experienced in biopharmaceutical products with at least fifteen (15) years of experience in the pharmaceutical and life sciences industries, including the conduct of research, development and commercialization collaborations who (i) has not worked for or been engaged by either Party or its Affiliates in the seven (7)-year period immediately prior to selection of such individual, and (ii) does not own equity or debt in either Party or its Affiliates (other than equity or debt owned through a broad based mutual fund or exchange trade fund) (the “Arbitrator”),

which Arbitrator shall be identified within [***] after the end of such [***] period. Promptly following the identification of the Arbitrator, each Party shall submit its respective Arbitration Drafts to the Arbitrator and within [***] following the receipt of the latter of such Arbitration Drafts the Arbitrator shall select one of the Arbitration Drafts for the C5 Collaboration Agreement or the C5 Combination License Agreement, as applicable; provided that, for clarity, the Arbitrator shall be limited to selecting only one or the other of the Arbitration Drafts submitted for the C5 Collaboration Agreement or the C5 Combination License Agreement, as applicable, in each case, that most closely reflects the terms and intent of the C5 Agreements Term Sheet. The determination of the Arbitrator as to the selection of one Party’s Arbitration Draft for the C5 Collaboration Agreement or the C5 Combination License Agreement, as applicable, shall be binding and conclusive upon both Parties and their Affiliates.

(c)The (i) fees of the Arbitrator and (ii) costs and expenses of the arbitration shall be paid by the Party whose Arbitration Draft was not selected by the Arbitrator.

(d)The Parties agree not to disclose to any Third Party (other than to the Arbitrator, their respective counsel and other advisors) any portion of any Arbitration Draft submitted by another Party in the course of such proceedings.

4.8.3Prior to such time as the Parties enter into the C5 Agreements, Alnylam and its Affiliates shall not undertake any activity with respect to the C5 Product or C5 Combination Product that would be prohibited under a C5 Agreement once entered into pursuant to and as set forth in the C5 Agreements Term Sheet.

4.9Delay for Merger Control Filing. At the written request of either Party, the effectiveness of a given License Agreement or Co-Co Collaboration Agreement will be delayed for the Parties to make any required Merger Control Filing(s) and to cause the occurrence of the Merger Control Conditions. Each Party will provide the other Party with any information (including financial information) reasonably requested by such Party for purposes of determining whether a Merger Control Filing is required. If a Party determines that a Merger Control Filing is required, then each of Regeneron and Alnylam, as required under the applicable Antitrust Law(s), will make or cause to be made such filing(s) or notification(s) as promptly as practicable (but in any event within twenty (20) Business Days of such determination). The Parties will reasonably cooperate with one another to the extent necessary in the preparation of any such Merger Control Filing. Each Party will be responsible for its own costs and expenses associated with such Merger Control Filing, and will share equally all filing fees. Each of Regeneron and Alnylam hereby covenants and agrees to use reasonable efforts to eliminate any material concern on the part of any Governmental Authority regarding the legality of the License Agreement or Co-Co Collaboration Agreement including, if required by a Governmental Authority, promptly taking all reasonable steps to remove any and all impediments to the consummation of the License Agreement or Co-Co Collaboration Agreement, including using reasonable efforts to (i) obtain government antitrust clearance or approval, (ii) cooperate in good faith with any Governmental Authority investigation, and (iii) promptly produce documents and information if requested by a Governmental Authority. Each of Regeneron and Alnylam further covenants and agrees not to take any action that will have the effect of materially delaying, impairing, or impeding, the occurrence of the Merger Control Conditions with respect to the entry of the License Agreement or Co-Co Collaboration Agreement.

Notwithstanding the foregoing, nothing in this Section 4.9 (Delay for Merger Control Filing) will require either Party or such Party’s Affiliates to (a) disclose to the other Party any information that is subject to obligations of confidentiality or non-use owed to Third Parties (nor will either Party be required to conduct joint meetings with any Governmental Authority in which such information might be shared with the other Party), in each case, unless required by the applicable Governmental Authority, (b) to consent to the divestiture or other disposition of any of its or its Affiliates’ assets or to consent to any other structural or conduct remedy or (c) litigate with respect to any Antitrust Law.

5.1Grants to Regeneron. Subject to the terms and conditions of this Agreement, Alnylam hereby grants Regeneron:

5.1.1during the Term of this Agreement, on a Program-by-Program basis, subject to Section 5.4.2, an exclusive (including with regard to Alnylam and its Affiliates), non-transferable (except as permitted by Section 12.2), worldwide license (or sublicense), with the right to grant sublicenses in accordance with Section 5.3, under the Alnylam Product-Specific Patents and the Alnylam Product-Specific Know-How, to perform activities under the Candidate Discovery Plan for such Program and to Exploit the Collaboration Products under such Program in accordance with the Candidate Discovery Plan in the Field in the Territory, which license shall be fully paid-up;

5.1.2during the Term of this Agreement, on a Program-by-Program basis, a non-exclusive, non-transferable (except as permitted by Section 12.2), worldwide license (or sublicense), with the right to grant sublicenses in accordance with Section 5.3, under the Alnylam Core Technology Patents and the Alnylam Core Technology Know-How, to perform activities under the Candidate Discovery Plan for such Program and to Exploit the Collaboration Products under such Program in accordance with the Candidate Discovery Plan in the Field in the Territory, which license shall be fully paid-up;

5.1.3during the Term of this Agreement, on a Program-by-Program basis, subject to Section 5.4.2, an exclusive (including with regard to Alnylam and its Affiliates), non-transferable (except as permitted by Section 12.2), fully paid-up, worldwide license and right of reference, with the right to grant sublicenses and further rights of reference in accordance with Section 5.3, under the Regulatory Approvals and any other Regulatory Documentation that Alnylam or its Affiliates may Control that are related to a Collaboration Product under such Program as necessary for purposes of performing any activities under the applicable Candidate Discovery Plan for such Program and for Exploiting such Collaboration Product in accordance with the applicable Candidate Discovery Plan for such Program in the Field in the Territory; and

5.1.4a non-exclusive, non-transferable (except as permitted by Section 12.2), fully paid-up, perpetual, worldwide license (or sublicense), with the right to grant sublicenses through multiple tiers, under the [***] to Exploit any product in the Territory that does not contain any siRNA, MicroRNA, MicroRNA antagonist or MicroRNA Mimic, or any single or double-stranded oligonucleotide designed to specifically hybridize to RNA and modulate the expression of the intended target.

Notwithstanding the foregoing in this Section 5.1, Regeneron does not receive any rights under the license grants in this Section 5.1 to or for any Proprietary Unlicensed Component of a Combination Product Controlled by Alnylam (or any of its Affiliates).

5.2Grants to Alnylam. Subject to the terms and conditions of this Agreement, Regeneron hereby grants Alnylam:

5.2.1during the Term of this Agreement, on a Program-by-Program basis, a non-exclusive, non-transferable (except as permitted by Section 12.2), fully paid-up, worldwide license (or sublicense), with the right to grant sublicenses in accordance with Section 5.3, under the Regeneron Technology, to perform activities under the Candidate Discovery Plan for such Program and to Exploit the Collaboration Products under such Program in accordance with the Candidate Discovery Plan in the Field in the Territory, which license shall be fully paid-up; and

5.2.2a non-exclusive, non-transferable (except as permitted by Section 12.2), fully paid-up, perpetual, worldwide license (or sublicense), with the right to grant sublicenses through multiple tiers, under the [***] to Exploit any product in the Territory containing siRNA (other than a Competing Product hereunder or a Competing Product (as defined in any then-existing License Agreement or Co-Co Collaboration Agreement)).

Notwithstanding the foregoing in this Section 5.2, Alnylam does not receive any rights under the license grants in this Section 5.2 to or for any Proprietary Unlicensed Component of a Combination Product Controlled by Regeneron (or any of its Affiliates).

5.3Sublicenses. Either Party shall have the right to grant sublicenses (or further rights of reference), through multiple tiers, under the licenses and rights of reference granted to Regeneron in Section 5.1.1, Section 5.1.2, or Section 5.1.3 or to Alnylam in Section 5.2.1, as applicable; provided that any such sublicenses to Develop a Collaboration Product shall be consistent with the terms and conditions of this Agreement and shall contain terms and conditions consistent with those in this Agreement and any such sublicense agreements shall first be approved by the Joint Steering Committee pursuant to Section 2.1.2(l); provided, however, that if any such sublicense agreement is between either Party and one or more of such Party’s Affiliates, then no prior approval is required. Each sublicense agreement entered into by a Party shall contain a requirement that the Sublicensee comply with confidentiality and non-use provisions that are no less stringent than Section 8.1 with respect to the other Party’s Confidential Information. Furthermore, the applicable Party shall use commercially reasonable efforts to ensure that, to the extent possible, each such sublicense agreement by it to a Sublicensee provides that any and all data and results, discoveries, inventions and other Information, whether patentable or not, arising out of the sublicense are owned by such Party or one of its Affiliates; provided that if, after using

commercially reasonable efforts, the foregoing is not possible, then such Party shall ensure that it sufficiently Controls all such data and results, discoveries, inventions and other Information in order to grant the licenses to the other Party as contemplated under this Agreement. Notwithstanding any sublicense to a Sublicensee, the sublicensing Party shall remain responsible to the other Party for the performance of all of the sublicensing Party’s obligations under, and compliance with, all applicable terms and conditions of, this Agreement, including any obligations delegated to its Sublicensees. For the avoidance of doubt, either Party may grant sublicenses, through multiple tiers, under the licenses granted to such Party under Section 5.1.4 or Section 5.2.2, as applicable, without the consent of the other Party and the foregoing provisions of this Section 5.3 shall not apply to such sublicenses.

5.4.1Except as expressly provided herein, nothing in this Agreement grants either Party or vests in either Party any right, title or interest in and to the Information, Patent Rights, Confidential Information, Trademarks or other intellectual property of the other Party (either expressly or by implication or estoppel), other than the license rights expressly granted hereunder and the assignments expressly made hereunder.

5.4.2Notwithstanding anything to the contrary in this Agreement, and without limiting any rights granted or reserved to Alnylam pursuant to any other term or condition of this Agreement, Alnylam hereby expressly retains, on behalf of itself and its Affiliates (and on behalf of its licensors, (sub)licensees and contractors) all right, title and interest in and to the Alnylam Technology to (a) perform its and their obligations under this Agreement, including to perform all activities under the Candidate Discovery Plan and (b) subject to Sections 4.6 and 5.7, develop, obtain and maintain regulatory approvals for, and to manufacture, commercialize, and otherwise exploit any compound or product, other than a Collaboration Product, in any field anywhere in the world.

5.5.2Additional Alnylam In-Licenses. In the event that a Patent Right licensed to Alnylam under an Additional Alnylam In-License actually is or will be infringed by Regeneron’s Development or Manufacture of a Collaboration Product in the Field and in the Territory in accordance with this Agreement, then such Additional Alnylam In-License will thereafter automatically be deemed to be an Existing Alnylam In-License on a Collaboration Product-by-Collaboration Product basis, and all rights granted to Alnylam thereunder will be

deemed to be “Controlled” by Alnylam and sublicensed to Regeneron under the applicable terms of Section 5.1, effective as of the later of (a) the date the applicable Patent Right issues and (b) the date that Regeneron’s Development or Manufacture of such Collaboration Product in the Field and in the Territory in accordance with this Agreement under the applicable terms of Section 5.1 would infringe such Patent Right in the absence of a license thereunder from Alnylam; provided, for clarity, [***].

5.5.3Management of In-Licenses. Neither Party shall, and each Party shall cause its Affiliates not to, enter into any subsequent agreement or understanding with any Third Party to an In-License to which such Party or any of its Affiliates is a party that modifies, amends or terminates any such In-License, or waives any right or obligation thereunder, in any way that would adversely affect in any material respect the other Party’s rights or interests under this Agreement, including by increasing any of the other Party’s obligations or otherwise agreeing to any covenants or obligations imposed on the other Party that would adversely impact the other Party’s business outside of this Agreement, in each case, without the other Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed. Neither Party shall, and each Party shall cause its Affiliates not to, commit any acts or permit the occurrence of any omissions that would cause a material breach or termination of any such In-License that would adversely affect in any material respect the other Party’s rights or interests under this Agreement.

5.5.4In-Licenses. Each Party acknowledges and agrees that the sublicenses and other rights granted by the other Party to such first Party in this Agreement are subject to the terms of any In-Licenses to which such other Party or any of its Affiliates is a party. Each Party granted a sublicense pursuant to this Agreement under any of the In-Licenses of the other Party (or any of its Affiliates) (the Party granted a sublicense, the “Sublicensed Party,” and the Party granting the sublicense, the “Sublicensor Party”) shall comply with, and perform and take such actions as may be required to allow the Sublicensor Party to comply with, all applicable terms and conditions of the In-Licenses of the Sublicensor Party to the extent (a) applicable to (i) the Sublicensed Party’s rights or obligations relating to the Development or Manufacture of Collaboration Products under this Agreement or (ii) the filing, prosecution, maintenance, extension, defense, enforcement or the further sublicensing of the Alnylam Technology (if Alnylam is the Sublicensor Party) or the Regeneron Technology (if Regeneron is the Sublicensor Party) to the extent relevant to the Sublicensed Party’s rights or obligations relating to the Development or Manufacture of Collaboration Products under this Agreement, and (b) the Sublicensed Party has been given written notice or provided a copy of such terms and conditions on or before the later of (i) the Execution Date and (ii) the date on which such In-License is first required to have been provided to the Sublicensed Party hereunder, including any such terms and conditions relating to sublicensing, patent matters, confidentiality, reporting, audit rights, indemnification and diligence. Without limiting the foregoing, (x) the Parties shall, from time to time, upon the reasonable request of either Party, discuss the terms of any In-License and (y) each Sublicensed Party shall prepare and deliver to the Sublicensor Party any reports required under the applicable In-Licenses of the Sublicensor Party sufficiently in advance to enable the Sublicensor Party to comply with its obligations under the applicable In-Licenses, to the extent that the Sublicensed Party had been made aware of such provisions sufficiently in advance of the date on which such compliance is required in order for such Sublicensed Party to properly prepare such reports.

5.5.5Excluded Agreements. Notwithstanding anything herein to the contrary, Regeneron acknowledges that certain Patent Rights and Information under which Alnylam has rights are in-licensed by Alnylam under the Excluded Agreements. It is understood and agreed that no sublicense is granted to Regeneron by Alnylam under the Excluded Agreements pursuant to this Agreement, and that no Patent Rights or Information licensed to Alnylam under the Excluded Agreements will be Controlled by Alnylam under this Agreement.

5.6Confirmatory Patent License. Each Party shall, if requested to do so by the other Party, promptly enter into confirmatory license agreements in the form or substantially the form reasonably requested by such other Party for purposes of recording the licenses granted under this Agreement with such patent offices in the Territory as the requesting Party considers appropriate. Until the execution of any such confirmatory licenses, so far as may be legally possible, Alnylam and Regeneron shall have the same rights in respect of the respective intellectual property and be under the same obligations to each other in all respects as if the said confirmatory licenses had been executed.

(a)Collaboration Target Exclusivity. On a Collaboration Target-by-Collaboration Target basis, during the Term, subject to Section 5.7.2, Section 5.7.3 and Section 5.7.4, and the remainder of this Section 5.7.1(a), and in the case of Alnylam, except as and to the extent set forth in the Existing Alnylam Third Party Agreements and in the case of Regeneron except as and to the extent set forth in the Existing Regeneron Third Party Agreements, in each case, as existing as of the Effective Date, each Party shall not, and shall cause its Affiliates not to, (i) directly or indirectly, develop, commercialize or manufacture for purposes of development or commercialization, any Competing Product with respect to such Collaboration Target in the Field in any country in the Territory, or (ii) license, authorize or appoint any Third Party to directly or indirectly, develop, commercialize or manufacture for purposes of development or commercialization, any Competing Product with respect to such Collaboration Target in the Field in any country in the Territory.

(A)Exceptions to Exclusivity for Terminated Targets or Declined Targets. The provisions of Section 5.7.1(a)(i) and (ii) shall no longer apply to any Collaboration Target that becomes a Terminated Target or a Declined Target (or any Competing Product Directed to such Terminated Target or Declined Target, provided that such Competing Product is not also Directed to a different Collaboration Target, whereupon Section 5.7.1(a)(i) and (ii) will continue to apply).

(A)Exceptions to Exclusivity for Terminated Targets or Declined Targets. The provisions of this Section 5.7.1(b)(i) and (ii) shall no longer apply to any Terminated Target or a Declined Target (or any Competing Product Directed to such Terminated Target or Declined Target, provided that such Competing Product is not also Directed to a different Eye Target or CNS Target, whereupon Section 5.7.1(b)(i) and (ii) will continue to apply).

(B)Exceptions to Exclusivity for Alnylam Reserved Target. The provisions of Section 5.7.1(b)(i) and (ii) shall not apply to the Alnylam Reserved Target (or any Competing Product Directed to such Alnylam Reserved Target; provided that such Competing Product is not also Directed to a different Eye Target or CNS Target, whereupon Section 5.7.1(b)(i) and (ii) will continue to apply).

(c)siRNA Sequence Exclusivity. Without limiting the provisions of Sections 5.7.1(a) and 5.7.1(b), during the Term, Alnylam shall not, and shall cause its Affiliates not to, (i) directly or indirectly, develop, commercialize or manufacture for purposes of development or commercialization any siRNA that includes the same nucleotide sequence (or a different nucleotide sequence that functionally targets the same nucleotide sequence of the messenger RNA) as a Collaboration Product, except for [***], or (ii) license, authorize or appoint any Third Party to directly or indirectly, develop, commercialize or manufacture for purposes of development or commercialization any siRNA that includes the same nucleotide sequence (or a different nucleotide sequence that functionally targets the same nucleotide sequence of the messenger RNA) as a Collaboration Product, except for [***]; provided that in each case ((i)-(ii)), [***].

(d)License Agreements and Co-Co Collaboration Agreements. Notwithstanding the foregoing provisions of this Section 5.7.1, if a License Agreement or Co-Co Collaboration Agreement is entered into with respect to a given Program, then the foregoing provisions of this Section 5.7.1 shall no longer apply to the Collaboration Target under such Program (or any Competing Product Directed to such Collaboration Target), and, for clarity, the provisions of the License Agreement or Co-Co Collaboration Agreement, as applicable, shall thereafter apply with respect to such Collaboration Target (and any Competing Product Directed to such Collaboration Target), but without prejudice to any rights that shall have accrued (or that may accrue as a result of activities under this Agreement) to the benefit of a Party prior to entering into such License Agreement or Co-Co Collaboration Agreement. Notwithstanding the foregoing, in the event of the occurrence of a Third Party Acquisition during the Term (prior to such time as such License Agreement or Co-Co Collaboration Agreement is entered into for the applicable Program) pursuant to which there was a Competing Program or Acquisition Product as set forth in Section 5.7.2 and Section 5.7.3 with respect to the Collaboration Target that was the subject of such Program, then such Competing Program or Acquisition Product, as applicable, shall be considered a “Competing Program” or “Acquisition Product”, as applicable, under the License Agreement or Co-Co Collaboration Agreement, as applicable, and the time periods set forth therein for taking action with respect to such “Competing Program” or “Acquisition Product” shall be counted beginning as of the time of the Third Party Acquisition under this Agreement, and any other adjustments contemplated by Section 5.7.2(f) shall also continue to be applicable under the equivalent provisions of the applicable License Agreement or Co-Co Collaboration Agreement.

(a)If, during the Term, (i) there is a Change of Control of a Party (such Party, the “Acquired Party”) and as of the effective date of such Change of Control, a Third Party described in the definition of “Change of Control” or any of its Affiliates (other than the Acquired Party, or the Acquired Party’s Pre-Existing Affiliates) (the “Acquirer”) is engaged, directly or indirectly, in any activities that, if carried out by the Acquired Party, would be a breach of the exclusivity obligations set forth in Section 5.7.1 (such activities, a “Competing Program”), or (ii) as the result of an acquisition of a Third Party or the assets of a Third Party by a Party or one or more of its Affiliates (the “Acquiring Party”), the Acquiring Party directly or indirectly acquires rights to a Competing Product in the Field that would be a breach of the exclusivity obligations set forth in Section 5.7.1 (each such Competing Product, an “Acquisition Product” and each transaction described in subsection (i) or (ii), a “Third Party Acquisition”); then, the Acquired Party or Acquiring Party, as applicable, shall give the other Party (the “Non-Acquiring Party”) express written notice thereof within ten (10) Business Days after the closing of such Third Party Acquisition and furthermore the Acquired Party or Acquiring Party, as applicable, shall in its sole discretion do one of the following after the closing of such Third Party Acquisition: (w) by the later of six (6) months after (i) such closing, (ii) the expiration of the Divestment Period pursuant to Section 5.7.2(b) and (iii) the date on which the Parties cease negotiations pursuant to Section 5.7.2(c), as applicable, terminate all development, commercialization and manufacture for purposes of development or commercialization, with respect to such Competing Program or Acquisition Product, as applicable (other than Clinical Trials that a Regulatory Authority requires the Acquired Party or Acquiring Party, as applicable, to continue, which may be continued for no more than twelve (12) months after such closing or such longer period as such Regulatory Authority requires), and deliver to the Non-Acquiring Party a notice of such termination, which notice shall include a covenant that no further development, commercialization or manufacture for purposes of development or commercialization, with respect to such Competing Program or Acquisition Product shall be performed by or on behalf of such Acquired Party or Acquiring Party, as applicable, or any of its Affiliates, to the extent the provisions of Section 5.7.1 would have prohibited such activities; provided, that an Acquired Party or Acquiring Party, as applicable, shall not be prohibited from later divesting its rights in such terminated Competing Program or Acquisition Product, as applicable, whether pursuant to the provisions of this Section 5.7.2 or otherwise; (x) divest its rights in the Competing Program or Acquisition Product to a Third Party pursuant to Section 5.7.2(b); (y) offer the Competing Product Option to the Non-Acquiring Party pursuant to Section 5.7.2(c) or (z) if applicable, exercise the right to continue the Competing Program as set forth in Section 5.7.2(d). If the Acquired Party or Acquiring Party fails to comply with one of the foregoing clauses (w), (x), (y) or (z), then, unless the Parties otherwise agree in writing, the Acquired Party or Acquiring Party, as applicable, shall be in breach of Section 5.7.1.

such one hundred eighty (180)-day period; provided, that if the Acquired Party or Acquiring Party, as applicable, fails to complete such divestiture within such one hundred eighty (180)-day period, but can demonstrate to the Non-Acquiring Party’s reasonable satisfaction that it used commercially reasonable efforts to effect such divestiture within such one hundred eighty (180)-day period, then, unless otherwise required by Applicable Law, such one hundred eighty (180)-day period shall be extended for such additional reasonable period thereafter as is necessary to enable such Competing Program or Acquisition Product, as applicable, to be in fact divested, not to exceed an additional one hundred and eighty (180) days; provided, however, that such period shall be extended for such period as is necessary to obtain any governmental or regulatory approvals required to complete such divestiture, provided that the Acquired Party or Acquiring Party, as applicable, is using good faith efforts to obtain such approvals (such period, the “Divestment Period”). If the Acquired Party or Acquiring Party, as applicable, does not complete the divestiture within the Divestment Period, then the Acquired Party or Acquiring Party, as applicable, shall terminate such Competing Program or Acquisition Product, as applicable pursuant to Section 5.7.2(a), or, provided such Competing Program or Acquisition Product has not previously been the subject of a Competing Product Option, offer the Non-Acquiring Party the option to include the Competing Program or Acquisition Product as a Collaboration Product under this Agreement pursuant to Section 5.7.2(c). Any divestiture of rights under this Section 5.7.2(b) shall not permit the Acquired Party or Acquiring Party, as applicable, or its Affiliates to retain any rights in (other than the right to receive payments) or involvement with the Competing Program or Acquisition Product, as applicable, including rights to direct or influence the course of development or commercialization thereof, or to contribute or receive nonpublic know-how or information of any sort with respect thereto (other than reports showing the basis for calculating payments made to the Acquired Party or Acquiring Party, as applicable, and the right to audit the accuracy of such reports); provided, that the Acquired Party or Acquiring Party, as applicable, may continue to supply the applicable Competing Product to the acquirer and provide other transitional services for a reasonable transitional period until the acquirer is able to establish its own source of supply of such Competing Product and provider for such services. If the Acquired Party or Acquiring Party, as applicable, elects to divest the Competing Program or Acquisition Product, the Acquired Party or Acquiring Party, as applicable, shall not be precluded under Section 5.7.1 from conducting any activities (either directly, or with or through any Third Party) with respect to such Competing Program or Acquisition Product during the applicable Divestment Period; provided, that any such activities are subject to appropriate firewall procedures to segregate such activities (and the personnel conducting such activities) from the activities performed by or on behalf of the Acquired Party or Acquiring Party, as applicable, pursuant to this Agreement to ensure that no Confidential Information of the Non-Acquiring Party and no other information generated under this Agreement is used in connection with such Competing Program or Acquisition Product.

(c)If the Acquired Party or Acquiring Party, as applicable, chooses to offer to the Non-Acquiring Party the option to include the Competing Program or Acquisition Product as a Collaboration Product under this Agreement (including to the extent possible under an existing Program) (the “Competing Product Option”), the Acquired Party or Acquiring Party, as applicable, shall provide a Competing Product Option Data Package to the Non-Acquiring Party within thirty (30) days after the closing of such Third Party Acquisition. If the Non-Acquiring Party is interested, in its sole discretion, in exercising the Competing Product Option, it shall provide written notice thereof to the Acquired Party or Acquiring Party, as applicable, within

thirty (30) days of receipt of the Competing Product Option Data Package and, promptly thereafter, the Parties shall negotiate in good faith the terms pursuant to which such Competing Program or Acquisition Product would be included as a Program or a Collaboration Product, as applicable, under this Agreement. If the Parties do not reach agreement within ninety (90) days after beginning such good faith negotiations, then the Acquired Party or Acquiring Party, as applicable, shall either terminate such Competing Program or Acquisition Product or divest its rights in such Competing Program or Acquisition Product pursuant to this Section 5.7.2.

(d)Notwithstanding anything in this Section 5.7.2 to the contrary, if during the Term there is a Third Party Acquisition as described in Section 5.7.2(a)(i), then as a limited exception to the exclusivity obligation in Section 5.7.1(a) (and in Section 5.7.1(c), but with respect to Section 5.7.1(c), this Section 5.7.2(d) shall only apply to [***] in the event that an Acquirer owns or in-licenses a Competing Program at the time of the closing of the Third Party Acquisition, then the Acquired Party may offer the Non-Acquiring Party the right to enter into a License Agreement with respect to those Programs for Collaboration Targets with respect to which the Competing Program violates the provisions of Section 5.7.1(a) (or the provisions of Section 5.7.1(c), but with respect to Section 5.7.1(c), only for such given Competing Product) by providing a written notice to the other Party (a “Competing Program Opt-Out Election Notice”) within ten (10) Business Days after the closing of the Third Party Acquisition for the Acquired Party. In such case if so offered, the Non-Acquiring Party shall have the right, in its sole discretion, to elect to enter into a License Agreement for any such Program(s) with the Non-Acquiring Party as the “Licensee” thereunder (which election may be made by non-Acquired Party on a Program-by-Program basis), by providing written notice of such election to Acquired Party within sixty (60) days after receipt of the Competing Program Opt-Out Election Notice from the Acquired Party (the “Competing Program Election Period”). If the Non-Acquiring Party makes its election to enter into a License Agreement for any such Program during the Competing Program Election Period, then the Parties, subject to Section 4.9, shall enter into a License Agreement with respect to such Program (and the Collaboration Target and Collaboration Products thereunder), including completing the exhibits and schedules thereto, with the Non-Acquiring Party as the “Licensee” under such License Agreement (and, subject to Section 4.9, pending such time as the License Agreement is entered into for such Program, the Acquired Party shall, and hereby does, grant to the Non-Acquiring Party the licenses as set forth in the License Agreement with respect to such Program (including the Collaboration Target and Collaboration Products thereunder)). For the avoidance of doubt the provisions of Section 4.5 and 4.7 shall apply with respect to any such License Agreement. If the Non-Acquiring Party does not make its election to enter into the License Agreement for a given Program during the Competing Program Election Period as set forth in this Section 5.7.2(d), then such Program shall continue hereunder in accordance with the terms and conditions of this Agreement. Notwithstanding the provisions of Section 5.7.1(a) (or Section 5.7.1(c), but with respect to Section 5.7.1(c), only for such given Competing Product), in the event that the Acquired Party provides the Competing Program Opt-Out Election Notice for the Competing Program with respect to any Collaboration Target (it being understood that, with respect to a Competing Program for any Pre-Cleared Target that is not a Collaboration Target as of the time of the closing of the Third Party Acquisition, because there is no Program that can be offered to the Non-Acquiring Party, the Acquired Party may still invoke the provisions of this Section 5.7.2(d) with respect to the applicable Competing Program, but the Non-Acquiring Party shall be deemed to have declined its right to enter a License Agreement with respect thereto; provided that if such Pre-Cleared Target is ever named as a Collaboration Target hereunder and Alnylam or any of its Affiliates (alone or with one or more Third Party(ies)) is then or thereafter developing, commercializing or manufacturing for purposes of development or commercialization, any Competing Program, then the provisions of this Section 5.7.2(d) shall

again apply, mutatis mutandis, and Alnylam shall provide to Regeneron a Competing Program Opt-Out Election Notice with respect to the Competing Program within thirty (30) days thereafter), then the Acquirer and its Affiliates (other than Pre-Existing Affiliates) shall have the right to continue to develop, manufacture, commercialize and exploit such Competing Program without being in violation of the provisions of Section 5.7.1(a) (or Section 5.7.1(c), but with respect to Section 5.7.1(c), only for such given Competing Product); provided that if the non-Acquired Party does not elect to enter into a License Agreement for a given Program if so offered above, then the Acquirer shall or shall cause the Acquired Party to (i) continue to fulfill its obligations under this Agreement (and under any Co-Co Collaboration Agreement or License Agreement, as applicable, with respect to such Program), in all respects, (ii) ensure that the conduct of Competing Program activities is completely independent of the activities conducted under or in connection with this Agreement (and under any Co-Co Collaboration Agreement or License Agreement, as applicable, with respect to such Program), (iii) ensure that all Competing Program activities (A) do not use, access or incorporate and are not based on any Alnylam Know-How, Regeneron Know-How or other Confidential Information, for so long as such Confidential Information remains subject to the confidentiality and non-use obligations under Section 8.1, and (B) are not covered by and do not incorporate or reference the Alnylam Patents or Regeneron Patents (or any Information or inventions disclosed in any of the foregoing) and (iv) establish reasonable internal safeguards designed to prevent any Alnylam Know-How, Regeneron Know-How or other Confidential Information from being disclosed to, or otherwise utilized by, the Acquirer or any of its Affiliates (other than Pre-Existing Affiliates), in connection with the Competing Program, for so long as such Confidential Information remains subject to the confidentiality and non-use obligations under Section 8.1.

(e)Notwithstanding anything in this Section 5.7.2 to the contrary [***] provided that the Acquirer shall or shall cause the Acquired Party to (i) continue to fulfill its obligations under this Agreement (and under any Co-Co Collaboration Agreement or License Agreement, as applicable, with respect to such Program), in all respects, (ii) ensure that the conduct of Competing Program activities is completely independent of the activities conducted under or in connection with this Agreement (and under any Co-Co Collaboration Agreement or License Agreement, as applicable, with respect to such Program), (iii) ensure that all Competing Program activities (A) do not use, access or incorporate and are not based on any Alnylam Know-How, Regeneron Know-How or other Confidential Information, for so long as such Confidential Information remains subject to the confidentiality and non-use obligations under Section 8.1, (B) are not covered by and do not incorporate or reference the Alnylam Patents or Regeneron Patents (or any Information or inventions disclosed in any of the foregoing), and (C) only use the Patent Rights or Information controlled by such Acquirer (or any of its Affiliates, other than the Pre-Existing Affiliates) at the time of such closing, and improvements to such Patent Rights or Information, and any other Patent Rights or Information first acquired or in-licensed by such Acquirer (or any of its Affiliates, other than the Acquired Party and its Pre-Existing Affiliates) from a Third Party after the closing of the Change of Control transaction (and improvements thereto), and (iv) establish reasonable internal safeguards designed to prevent any Alnylam Know-How, Regeneron Know-How or other Confidential Information from being disclosed to, or otherwise utilized by, the Acquirer or any of its Affiliates (other than Pre-Existing Affiliates), in connection with the Competing Program, for so long as such Confidential Information remains subject to the confidentiality and non-use obligations under Section 8.1.

(f)Notwithstanding anything in this Agreement to the contrary, following the closing of a Change of Control of an Acquired Party, the Parties agree that (x) the Non-Acquiring Party shall not obtain rights or access to the Patent Rights or Information controlled by the Acquirer or any of the Affiliates of such Acquirer (other than the Acquired Party and its Affiliates that exist immediately prior to the closing of such Change of Control and any successor thereto (such Affiliates of the Acquired Party, the “Pre-Existing Affiliates”)) at the time of such closing (and improvements to such Patent Rights or Information) and any other Patent Rights or Information first acquired or in-licensed by such Acquirer (or any of its Affiliates, other than the Acquired Party and its Pre-Existing Affiliates) from a Third Party after the closing of the Change of Control transaction (and improvements thereto) (so that, for clarity, none of the foregoing in this clause (x) will be treated as Controlled by Alnylam or any of its Affiliates, or by Regeneron or any of its Affiliates, as applicable, based on which Party is the Acquired Party), and (y) the Acquirer and its Affiliates (other than the Acquired Party and its Pre-Existing Affiliates) shall not obtain rights or access to the Patent Rights or Information controlled by the Non-Acquiring Party or any of its Affiliates pursuant to this Agreement, other than in connection with the Exploitation of any Collaboration Products as provided under this Agreement; provided that clause (x) of this Section 5.7.2(f) shall not apply to any Patent Rights or Information controlled by the Acquirer or any of its Affiliates to the extent such Patent Right or Information (i) is used by or on behalf of the Acquired Party or any of its Affiliates in performing any of the Acquired Party’s obligations under this Agreement; (ii) is incorporated into any Collaboration Product by or on behalf of the Acquired Party or any of its Affiliates; or (iii) was generated after the closing of such Change of Control through any use of, or access to, any Alnylam Know-How (with respect to Alnylam as the Acquired Party) or any Regeneron Know-How (with respect to Regeneron as the Acquired Party) or is otherwise Covered by any Alnylam Patent (with respect to Alnylam as the Acquired Party) or any Regeneron Patent (with respect to Regeneron as the Acquired Party); provided that, (A) with respect to Alnylam as the Acquired Party, if the Acquirer or any of its Affiliates was party to an agreement with Alnylam or any Pre-Existing Affiliate on or prior to the date of such Change of Control pursuant to which the Acquirer or such Affiliates received a license to any Information or Patent Rights controlled by Alnylam or its Pre-Existing Affiliates other than any Alnylam Product-Specific Know-How or Alnylam Product-Specific Patents, then this clause (iii) shall not apply to any Patent Rights or Information controlled or generated by Acquirer or such Affiliates under such agreement prior to such Change of Control that were not Controlled by Alnylam or any Pre-Existing Affiliate or (B) with respect to Regeneron as the Acquired Party, if the Acquirer or any of its Affiliates was party to an agreement with Regeneron or any Pre-Existing Affiliate on or prior to the date of such Change of Control pursuant to which the Acquirer or such Affiliates received a license to any Information or Patent Rights controlled by Regeneron or its Pre-Existing Affiliates other than any Regeneron Product-Specific Know-How or Regeneron Product-Specific Patents, then this clause (iii) shall not apply to any Patent Rights or Information controlled or generated by Acquirer or such Affiliates under such agreement prior to such Change of Control that were not Controlled by Regeneron or any Pre-Existing Affiliate. Without limiting the foregoing, in all cases, the Non-Acquiring Party’s rights in all Patent Rights and Information Controlled by the Acquired Party or any of its Pre-Existing Affiliates, or any of their respective successors, and all improvements thereto, shall remain licensed to such Non-Acquiring Party after the date of the closing of such Change of Control in accordance with and subject to the terms and conditions of this Agreement and shall not be affected in any manner by virtue of such Change of Control.

5.7.3Regeneron Exceptions. Notwithstanding the exclusivity obligation in Section 5.7.1:

(a)Regeneron reserves the right to grant licenses to Third Parties to use intellectual property owned or otherwise controlled by Regeneron or its Affiliates related to research-enabling technologies, discovery-enabling technologies or manufacturing-related technologies, including Regeneron Technology, and rights to Regeneron Mice, but excluding Alnylam Technology, Regeneron Product-Specific Patents, and Regeneron Product-Specific Know-How (“Excluded Collaboration Technology”), which licenses, during the Term, may be for general purposes not specific to Competing Products (i.e., that is not specific to the Manufacture of any particular Competing Product), but which may involve the exploitation of Competing Products in the Field, and such grant and any associated disclosure or provision of such intellectual property or provision of technical assistance using only such intellectual property in connection therewith shall not constitute a breach of this Agreement (including Section 5.7.1); provided that Regeneron and its Affiliates will not otherwise actively assist any Third Party (other than through the grant of such license or provision of such technical assistance) in developing or commercializing any Competing Product in the Field if doing so would not comply with Section 5.7.1, but, for clarity, may receive license fees, milestones and royalties in connection with exploitation by Third Parties of any Competing Products in the Field generated by such Third Parties.

(b)Regeneron reserves the right to grant licenses to Third Parties to use any clinical, genomic, and molecular data maintained by the Regeneron Genetics Center, other than any such data that is Excluded Collaboration Technology, for any purpose, which may involve activities with respect to Competing Products in the Field, and such grant and any associated disclosure or provision of such data or provision of technical assistance without the use of Excluded Collaboration Technology in connection therewith shall not constitute a breach of this Agreement (including Section 5.7.1); provided that, Regeneron and its Affiliates will not otherwise actively assist any Third Party (other than through the grant of such license or provisions of such technical assistance) in developing or commercializing any Competing Product in the Field if doing so would not comply with Section 5.7.1, but, for clarity, may receive license fees, milestones and royalties in connection with exploitation by Third Parties of any Competing Products in the Field generated by such Third Parties.

(c)The Parties acknowledge and agree that nothing in Section 5.7.1 prevents or limits Regeneron’s or its Affiliate’s rights to (i) settle any enforcement action or proceeding (including any counterclaim in any such action or proceeding), declaratory judgment action or similar action or claim, or any other litigation or proceeding involving an allegation of infringement or other violation of intellectual property or the invalidity or enforceability of any Patent Right owned or otherwise controlled by Regeneron or any of its Affiliates (other than with respect to intellectual property controlled by Regeneron or its Affiliates as a licensee of Alnylam under this Agreement), including by granting licenses or other rights under any such Patent Right to Third Parties in connection therewith or (ii) enter into an agreement to preempt, and thereby avoid the initiation of, any of the actions, proceedings, claims or other litigation set forth in clause (i), including by granting licenses or other rights under any such Patent Right to Third Parties in connection therewith; provided that, in either case ((i) or (ii)), neither Regeneron nor any of its Affiliates may grant a license or other right under any such Patent Right to a Third Party to make, have made, use, offer to sell, sell or import a generic version of a Collaboration Product in the Field, including any Generic Product, except pursuant to ARTICLE 7.

5.8Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Regeneron or Alnylam are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the Parties, as licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against either Party under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, the Party that is not a party to such proceeding shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, which, if not already in the non-subject Party’s possession, shall be promptly delivered to it (a) upon any such commencement of a bankruptcy proceeding upon the non-subject Party’s written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement, or (b) if not delivered under clause (a) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party.

5.9.7For purposes of this Agreement, the following defined terms shall have the following meanings:

6.1Upfront Payment. In consideration for the rights granted to Regeneron under this Agreement, Regeneron shall pay to Alnylam within ten (10) Business Days after the Effective Date a one-time upfront payment of Four Hundred Million Dollars ($400,000,000) (the “Upfront Payment”).

6.2Equity Agreements. The Parties will enter into the Equity Agreements as of the Execution Date.

6.4.1On a Program-by-Program basis, Regeneron shall pay to Alnylam the following amounts upon achievement of the following Development activities:

(a)During the Research Term and during the first twelve (12) months of the Research Term Tail, upon initiation of synthesis of a Collaboration Product by Alnylam under a given Program in accordance with the Candidate Discovery Plan for such Program, Regeneron shall pay to Alnylam a one-time payment of [***]; and

(b)Upon designation of the first Lead Candidate (i.e., a Collaboration Product that satisfies the Lead Candidate Criteria or the Parties otherwise mutually agree to designate a given Collaboration Product as a Lead Candidate) under a given Program pursuant to Section 4.2, in each case, during the Research Term or Research Term Tail for the applicable Program, Regeneron shall pay to Alnylam a one-time payment of [***] (the “Lead Candidate Payment”).

If any of the foregoing Development activities pursuant to this Section 6.4 are achieved for one or more Programs during a given Calendar Quarter, then Alnylam shall invoice Regeneron therefor after the end of the Calendar Quarter during which such activities were achieved, and Regeneron shall pay such invoice within thirty (30) days after receipt of such invoice. Each of the foregoing payments in this Section 6.4 shall be payable a maximum of one (1) time per Program regardless of the number of Collaboration Products under such Program and regardless of the number of Lead Candidates under such Program, and no additional payments shall be due hereunder for subsequent or repeated achievement of such events for such Program. For the avoidance of doubt, the maximum amount payable by Regeneron pursuant to this Section 6.4 is Five Million Dollars ($5,000,000) per Program assuming that each of the Development activities in this Section 6.4 were achieved for such Program.

6.4.2Any amounts payable by Regeneron to Alnylam pursuant to this Section 6.4 shall be used by Alnylam solely and exclusively to fund or reimburse the Development activities for Collaboration Products by Alnylam pursuant to this Agreement (provided that with respect to any amounts paid to Alnylam pursuant to Section 6.4.1 that remain unused at the end of the Term, such amounts shall be used to fund Development activities for Collaboration Products by Alnylam pursuant to the License Agreement or Co-Co Collaboration, as applicable), and for no other purpose.

6.5[***]. Subject to the terms of this Section 6.5, the Lead Continuation Party will notify the other Party promptly (but in all cases within thirty (30) days) following the first achievement by the Lead Continuation Party (either under a License Agreement or a Co-Co Collaboration Agreement, as applicable) of each milestone event described below in this Section 6.5, and Regeneron shall thereafter pay to Alnylam the applicable amounts set forth below associated with the applicable milestone event in accordance with Section 6.6 (each, a “[***]”):

Each of the foregoing [***] in this Section 6.5 shall be payable a maximum of one (1) time as set forth in the foregoing chart regardless of the number of Collaboration Targets achieving the applicable milestone event (i.e., a maximum of two (2) [***] may be made pursuant to this Section 6.5), and no additional [***] shall be due hereunder for subsequent or repeated achievement of such milestone event. For the avoidance of doubt, the maximum amount payable by Regeneron to Alnylam pursuant to this Section 6.5 is Two Hundred Million Dollars ($200,000,000), assuming that each of the milestone events in this Section 6.5 are achieved. In the event that (a) the Lead Continuation Party conducts a [***] for a given Eye Target or CNS Target (as applicable) but [***] was not achieved from such [***] and (b) such Lead Continuation Party thereafter Initiates a subsequent Clinical Trial that is later stage than the [***] for such Eye Target or CNS Target (as applicable) under a License Agreement or Co-Co Collaboration Agreement (as applicable) after [***]. In the event that the Parties disagree as to whether [***] has been achieved for a given [***] Target, then such dispute shall be an “Expert Dispute” and resolved by the Expert in accordance with Schedule 1.

6.6Invoice and Payment of Milestone Payments. Following receipt of notification by the Lead Continuation Party to the other Party that the applicable milestone event triggering a milestone payment pursuant to Section 6.5 has been achieved, Alnylam shall invoice Regeneron for the applicable milestone payment, and Regeneron shall pay each milestone payment sixty (60) days after receipt of the invoice therefor.

6.7Payment Method and Currency. All payments under this Agreement shall be made by bank wire transfer in immediately available funds to an account designated by the Party to which such payments are due. All sums due under this Agreement shall be payable in Dollars. In those cases where the amount due in Dollars is calculated based upon one or more currencies other than Dollars, such amounts shall be converted to Dollars at the average rate of exchange for the Calendar Quarter to which such payment relates using the arithmetic mean of the daily rate of exchange, as reported in Thomson Reuters Eikon (or any successor thereto) or any other source as agreed to by the Parties.

6.8Taxes. Either Party may withhold from payments due to the other 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. In such case, the payor Party will provide the payee Party all relevant documents and correspondence, and will also provide to the payee Party any other cooperation or assistance on a commercially reasonable basis as may be necessary to enable the payee Party to claim exemption from such withholding taxes and to receive a refund of such withholding tax or claim a foreign tax credit. The payor 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. Apart from any withholding permitted under this Section 6.8, the amounts payable hereunder will not be reduced on account of any taxes, charges, duties or other levies. Notwithstanding the foregoing, if, as a result of a Withholding Action by the paying Party (including any assignee or successor), any withholding or deduction of or on account of taxes, duties, levies, imposts, assessments, deductions, fees and other similar charges (“Withholding”) is required by Applicable Law and the amount of such Withholding exceeds the amount of Withholding that would have been required if the paying Party had not committed the Withholding Action, then the paying Party shall pay an additional amount to the receiving Party such that, after Withholding from the payment and such additional amount, the receiving Party receives the same amount as it would have received from the paying Party absent such Withholding Action by the paying Party. For the avoidance of doubt, if as a result of a Withholding Action by a receiving Party (including any assignee or successor) the amount of Withholding under the law of the applicable jurisdiction exceeds the amount of such Withholding that would been required in the absence of such Withholding Action by the receiving Party, the paying Party shall be required to pay any additional amount only to the extent that the paying Party would be required to pay any additional amount to the receiving Party pursuant to the preceding sentence if the receiving Party had not committed such Withholding Action. For purposes of this Section 6.8, “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 to become subject to tax in a jurisdiction outside of the United States or subject any payments to Withholding in any jurisdiction that would not have been required absent such Withholding Action.

6.9Resolution of Payment Disputes. In the event there is a dispute relating to any payment obligations or reports hereunder, the Party with the dispute shall provide the other Party with written notice setting forth in reasonable detail the nature and factual basis for such good faith dispute and the Parties will seek to resolve the dispute as promptly as possible, but no later than ten (10) Business Days after such written notice is received. If the Parties are unable to resolve such payment dispute within such period then the matter shall be resolved pursuant to Section 12.5. The Parties agree that if there is a dispute regarding any payment amount, only the disputed amount shall be withheld from the payment, and the undisputed amount shall be paid within the applicable timeframes.

6.10Late Fee. A late fee of [***] as reported on Thomson Reuters Eikon (or any successor thereto) (or another source agreed to by the Parties) on the date that the applicable payment was due may be charged by the Party to whom payment is due with respect to any payment amount from the date such payment amount was originally due under the terms of this Agreement until such payment amount is actually paid by one Party to another Party unless such payment amount is disputed, in which case the foregoing late fee shall commence on the date such dispute is resolved.

6.11Books and Records. Each Party shall (a) keep proper books of record and account in which full, true and correct entries (in conformity with Accounting Standards) shall be made for the purpose of determining the amounts payable or owed pursuant to this Agreement; (b) keep such books of record and account for at least three (3) Calendar Years following the Calendar Year to which they pertain (or such longer period to the extent required by Applicable Law) and (c) keep such books of record and account to the extent related to this Agreement in a readily available and organized form to allow an independent auditor to verify the accuracy of all financial, accounting and numerical information provided in an efficient manner. To the extent a Party is not in compliance with clause (c) of this Section 6.11, such Party shall be responsible for any additional fees charged by the independent auditor to the other Party as a result of additional time spent by the independent auditor assembling or organizing such information.

6.12.1Audit. Regeneron shall have the right, upon no less than [***] days’ advance written notice and at such reasonable places, times and intervals and to such reasonable extent as it shall request, not more than once during any Calendar Year, to have the books of record and account of Alnylam to the extent relating to this Agreement for the preceding [***] Calendar Years audited by an independent and nationally recognized accounting firm of its choosing and reasonably acceptable to Alnylam, for the sole purpose of verifying the accuracy of all financial, accounting and numerical information and calculations provided, and payments made, under this Agreement; provided, that absent evidence of fraud, gross negligence or willful misconduct no period may be subjected to audit more than one (1) time.

6.12.2Results; Costs; Confidentiality. The results of any such audit shall be delivered in writing to each Party and shall be final and binding upon the Parties, unless disputed by a Party by notice to the other Party within [***] days after delivery. If a Party over-billed or underpaid an amount due under this Agreement resulting in a cumulative discrepancy during any Calendar Year of more than the greater of [***] it shall also reimburse the other Party for the costs of the accounting firm to conduct such audit (with the cost of the audit to be paid by Regeneron in all other cases). Such accountants shall not reveal to Regeneron the details of its review, except for the results of such review and such information as is required to be disclosed under this Agreement, and shall be subject to the confidentiality provisions contained in ARTICLE 8. At the request of Alnylam prior to the audit, Regeneron shall cause its accounting firm to enter into a reasonably acceptable confidentiality agreement with Alnylam obligating such accounting firm to retain all such information in confidence pursuant to such confidentiality agreement.

6.12.3Reconciliation. If any examination or audit of the records described above discloses an overbilling or underpayment of amounts due hereunder, then unless the result of the audit is contested pursuant to Section 6.12.2, the Party that over-billed or underpaid shall pay the same to the Party entitled thereto within thirty (30) days after receipt of the written results of such audit pursuant to Section 6.12.1.

6.12.4Binding and Conclusive. Upon the expiration of the three (3) year period following the end of any Calendar Year, the calculation of the amounts payable with respect to such Calendar Year shall be binding and conclusive upon the Parties.

6.13Accounting Standards. Except as otherwise provided herein, all costs and expenses and other financial determinations with respect to this Agreement shall be determined in accordance with Accounting Standards, as generally and consistently applied.

7.1.1Ownership of Technology. Subject to Section 7.1.2, as between the Parties: (a) Regeneron shall own and retain all right, title and interest in and to any and all (i) Regeneron Collaboration IP and (ii) other Information, inventions, Patent Rights, and other intellectual property rights that are owned or otherwise Controlled by Regeneron, its Affiliates or its or their Sublicensees, including the Regeneron Technology, and (b) Alnylam shall own and retain all right, title and interest in and to any and all (i) Alnylam Collaboration IP and (ii) other Information, inventions, Patent Rights, and other intellectual property rights that are owned or otherwise Controlled by Alnylam, its Affiliates or its or their Sublicensees, including the Alnylam Technology. Regeneron shall own and retain all right, title and interest in and to any and all Regeneron Background Technology.

Specific aspects or details of Confidential Information shall 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. Further, any combination of Confidential Information shall 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.

8.2Permitted Disclosures. Each Party may disclose Confidential Information to the extent that such disclosure is:

8.2.1made in response to a valid order of a court of competent jurisdiction or other supra-national, federal, national, regional, state, provincial or local governmental or regulatory body of competent jurisdiction or, if in the reasonable opinion of the receiving Party’s legal counsel, such disclosure is otherwise required by Applicable Law, including by reason of filing with securities regulators; provided, however, that the receiving Party shall first have given notice to the disclosing Party and given the disclosing Party a reasonable opportunity to quash such order or to obtain a protective order or confidential treatment requiring that the Confidential Information and documents that are the subject of such order or required to be disclosed be held in confidence by such court or agency or, if disclosed, be used only for the purposes for which the order was issued or such disclosure was required by Applicable Law; and provided further that the Confidential Information disclosed in response to such court or governmental order or as required by Applicable Law shall be limited to that information which is legally required to be disclosed in response to such court or governmental order or by such Applicable Law;

The restrictions imposed by this Section 8.3 shall not prohibit either Party from making any disclosure identifying the other Party that is required by Applicable Law.

8.4Public Announcements. Following the Execution Date, the Parties shall issue a press release in a mutually agreed upon form. Neither Party shall issue any subsequent public announcement, press release, or other public disclosure regarding this Agreement or its subject matter without the other Party’s prior written consent, except for any such disclosure that is, in the opinion of the disclosing Party’s counsel, required by Applicable Law or the rules of a stock exchange on which the securities of the disclosing Party are listed (or to which an application for listing has been submitted) and except that a Party may, once a press release or other public written statement is approved in writing by both Parties, make subsequent public disclosure of the information contained in such press release or other public written statement without the further approval of the other Party. In the event a Party is, in the opinion of its counsel, required by

Applicable Law or the rules of a stock exchange on which its securities are listed (or to which an application for listing has been submitted) to make such a public disclosure, such Party shall submit the proposed disclosure in writing to the other Party as far in advance as reasonably practicable (and in no event less than [***] Business Days prior to the anticipated date of disclosure) so as to provide a reasonable opportunity to comment thereon. Notwithstanding the foregoing, on a Program-by-Program basis, the Lead Party, its Affiliates and its and their Sublicensees shall have the right to publicly disclose research, development and commercial information (including with respect to regulatory matters) regarding any Collaboration Product under such Program; provided (a) such disclosure is subject to the provisions of this ARTICLE 8 with respect to the Participating Party’s Confidential Information and (b) the Lead Party shall not use the name of the Participating Party (or insignia, or any contraction, abbreviation or adaptation thereof) without the Participating Party’s prior written permission. Notwithstanding the foregoing, to the extent that such disclosure describes the commencement or “top-line” results of Clinical Trials of a Collaboration Product, or the achievement of any material Development events with respect to a Collaboration Product in the Territory (each, a “Major Event”), the Lead Party will consider in good faith any request by the Participating Party to issue a joint press release or public disclosure with the Participating Party relating to a Major Event. Prior to making any public disclosure, to the extent practicable, the Lead Party shall provide the Participating Party with a draft of such proposed disclosure for the Participating Party’s review and comment, which shall be considered in good faith by the Lead Party. Such draft shall be provided to the Participating Party at least [***] (or, to the extent faster timely disclosure of a material event is required by Applicable Law or stock exchange or stock market rules, such shorter period of time sufficiently in advance of the disclosure so that the Participating Party will have the opportunity to comment upon the disclosure and the Lead Party will be able to comply with its obligations as required by Applicable Law or stock exchange or stock market rules) prior to making any such disclosure, for the Participating Party’s review and comment, which shall be considered in good faith by the Lead Party. Without limiting the foregoing, the Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement with the United States Securities and Exchange Commission or its equivalent in the Territory. Each Party shall be entitled to make such filings, except that the Parties shall cooperate with each other and use reasonable efforts to obtain confidential treatment of confidential, including trade secret, information in accordance with Applicable Law. The filing Party shall provide the non-filing Party with an advance copy of this Agreement marked to show provisions for which the filing Party intends to seek confidential treatment and shall reasonably consider the non-filing Party’s timely comments thereon and cooperate with such non-filing Party in seeking such confidential treatment and, upon the written request of the non-filing Party, shall request an appropriate extension of the term of the confidential treatment period. For the avoidance of doubt, each Party shall be responsible for its own legal and other costs in connection with any filing governed by the terms of this Section 8.4.

to comment and to recommend any changes it reasonably believes are necessary to preserve any Patent Rights or Information belonging in whole or in part to the Participating Party or that is the Confidential Information of the Participating Party. If the Participating Party informs the Lead Party that such publication, in the Participating Party’s reasonable judgment, could be expected to have a material adverse effect on any patentable invention owned by or licensed, in whole or in part, to the Participating Party, or on any Information that is Confidential Information of the Participating Party, the Lead Party shall delay or prevent such publication as follows: (i) with respect to a patentable invention, such publication shall be delayed sufficiently long (not to exceed [***] days) to permit the timely preparation and filing of a patent application; and (ii) with respect to Information that is Confidential Information of such Participating Party (other than the results of a Clinical Trial or any regulatory Information), such Information shall be deleted from the publication. The Lead Party will also consider in good faith any other comments of the Participating Party. Any publication shall include recognition of the contributions of the Participating Party according to standard practice for assigning scientific credit, either through authorship or acknowledgement, as may be appropriate.

8.6Return of Confidential Information.

Notwithstanding the foregoing, such other Party also shall be permitted to retain such additional copies of or any computer records or files containing such Confidential Information that have been created solely by such Party’s automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with such other Party’s standard archiving and back-up procedures, but not for any other use or purpose. All Confidential Information shall continue to be subject to the terms of this Agreement for the period set forth in Section 8.1. In the event that a given Program becomes a Terminated Program, then the provisions of this Section 8.6 shall apply, mutatis mutandis, to Confidential Information related solely to such Terminated Program. Notwithstanding the foregoing, in the event that the Parties have entered into a License Agreement or Co-Co Collaboration Agreement with respect to a given Program, then this Section 8.6 shall not apply with respect to Confidential Information related to such Program or the Collaboration Products thereunder.

8.7License Agreements and Co-Co Collaboration Agreements. On a Program-by-Program basis, if a License Agreement or Co-Co Collaboration Agreement, as applicable, is entered into with respect to a given Program, then the provisions of such License Agreement or Co-Co Collaboration Agreement, as applicable, shall thereafter apply with respect to Confidential Information (including public announcements and publications) related solely to such Program and the Collaboration Products thereunder, and the provision of this ARTICLE 8 shall no longer apply. If there is Confidential Information that relates to such Program and also to other Programs hereunder, then in the event of a conflict between the provisions of (i) this Agreement, on the one hand, and (ii) the License Agreement or Co-Co Collaboration Agreement, as applicable, for such Program, on the other hand, with respect to disclosure and non-use of such Confidential Information, the provisions of the License Agreement or Co-Co Collaboration Agreement, as applicable shall control.

10.2.2Control of Defense. If the Indemnifying Party elects in writing to the Indemnified Party that it will assume control of the defense of such Claim, the Indemnifying Party shall have the right to defend such Claim by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party; provided, however, that the Indemnifying Party may not enter into any compromise or settlement unless the Indemnified Party consents to such compromise or settlement, which consent shall not be unreasonably withheld, conditioned or delayed, and which consent shall be deemed given with respect to any Damages relating solely to the payment of money damages if such compromise or settlement includes as an unconditional term thereof, the giving by each claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim. If the Indemnifying Party does not elect to assume control of the defense of such Claim within forty-five (45) days of its receipt of notice thereof, or if the Indemnifying Party elects in writing to the Indemnified Party to cease maintaining control of the defense of such Claim, the Indemnified Party shall have the right upon at least ten (10) Business Days’ prior written notice to the Indemnifying Party of its intent to do so, to undertake the defense of such Claim for the account of the Indemnifying Party (with counsel reasonably selected by the Indemnified Party and approved by the Indemnifying Party, such approval not to be unreasonably withheld, conditioned or delayed), provided, that the Indemnified Party shall keep the Indemnifying Party apprised of all material developments with respect to such Claim and promptly provide the Indemnifying Party with copies of all correspondence and documents exchanged by the Indemnified Party and the opposing party(ies) to such Claim. The Indemnified Party may not compromise or settle such Claim without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, conditioned or delayed.

10.3Insurance.

It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under Section 10.1 or otherwise. Any insurance proceeds received by a Party in connection with any Damages shall be retained by such Party and shall not reduce any obligation of the other Party.

10.4License Agreements and Co-Co Collaboration Agreements. On a Program-by-Program basis, upon execution of a License Agreement or Co-Co Collaboration Agreement, as applicable, for such Program, the indemnification rights and obligations of the Parties with respect to such Program (including the Collaboration Target and Collaboration Products thereunder) shall thereafter be governed by the License Agreement or Co-Co Collaboration Agreement, as applicable, but without prejudice to any rights that shall have accrued (or that may accrue as a result of activities under this Agreement) to the benefit of a Party with respect to such Program (including the Collaboration Target and Collaboration Products thereunder) hereunder prior to entering into such License Agreement or Co-Co Collaboration Agreement.

11.1Term. Except as otherwise set forth in Section 12.18, this Agreement shall be effective as of the Effective Date and, unless earlier terminated in accordance herewith, shall continue in force and effect until, with respect to each Program hereunder, (a) such Program becomes a Terminated Program or (b) the Parties enter into a License Agreement or Co-Co Collaboration Agreement with respect to such Program (such period, the “Term”).

11.2Voluntary Termination of Research Collaboration. Regeneron shall have the right, in its sole discretion, to terminate the research collaboration under this Agreement as set forth in this Section 11.2 by providing ninety (90) days’ prior written notice to Alnylam (the “Research Collaboration Termination Notice”). In the event Regeneron provides such Research Collaboration Termination Notice, then (a) following such time as such notice is delivered, (i) the Parties will work to promptly wind-down, in compliance with Applicable Law, all activities under any ongoing Program, and (ii) no additional new Collaboration Targets or new Programs shall be added hereunder, and (b) effective upon the ninety (90) day anniversary of the delivery of the Research Collaboration Termination Notice, (i) all Programs hereunder shall become “Terminated Programs”, (ii) all Collaboration Targets hereunder shall become “Terminated Targets”, and (iii) the Research Term and the Research Term Extension Period shall end. In the event that a given Program becomes a “Terminated Program” pursuant to this Section 11.2 after the first dosing of the first non-human primate with Collaboration Product in the pilot non-human primate study under such Program (but before a Lead Candidate is designated from such Program), then Regeneron shall pay to Alnylam the Lead Candidate Payment for such Program within thirty (30) days after such Program becomes a “Terminated Program” pursuant to this Section 11.2. For the avoidance of doubt, any termination of research collaboration pursuant to this Section 11.2 shall not affect any License Agreement or Co-Co Collaboration Agreement that was previously entered into, which agreements shall continue in full force and effect in accordance with their terms.

11.3Voluntary Termination of Agreement. Regeneron may terminate this Agreement at will, in its sole discretion, in its entirety upon ninety (90) days’ prior written notice to Alnylam at any time. For the avoidance of doubt, any such termination of this Agreement shall not affect any License Agreement or Co-Co Collaboration Agreement that was previously entered into, which agreements shall continue in full force and effect in accordance with their terms.

11.4Termination for Material Breach. If either Party (the “Non-Breaching Party”) believes that the other Party (the “Breaching Party”) has materially breached this Agreement in a manner that fundamentally frustrates the value or essential characteristics of the transactions contemplated by this Agreement as a whole, then the Non-Breaching Party may deliver notice of such material breach to the Breaching Party (a “Default Notice”). If the Breaching Party does not dispute that it has committed such a material breach under this Agreement that results in the Non-Breaching Party having a right to terminate this Agreement, then if the Breaching Party fails to cure such breach, or fails to take steps as would be considered reasonable to effectively cure such breach, within ninety (90) days after receipt of the Default Notice, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party. If the Breaching Party

disputes that it has committed a material breach under this Agreement that results in the Non-Breaching Party having a right to terminate this Agreement, the dispute shall be resolved pursuant to Section 12.5. If, as a result of the application of such dispute resolution procedures, the Breaching Party is determined to have materially breached in a manner that fundamentally frustrates the value or essential characteristics of the transactions contemplated by this Agreement as a whole (an “Adverse Ruling”), then if the Breaching Party fails to complete the actions specified by the Adverse Ruling to cure such material breach within ninety (90) days after such ruling, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party; provided that if such compliance cannot be fully achieved within such ninety (90)-day cure period, then such cure period will be extended for a period of up to sixty (60) additional days (for a total cure period of one hundred fifty (150) days) if the Breaching Party prepares and provides to the Non-Breaching Party a reasonable written plan for curing such material breach and uses commercially reasonable efforts to cure such material breach in accordance with such written plan, and if such material breach is not cured within such one hundred fifty (150)-day period, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party.

11.5Termination for Insolvency. In the event that either Party (or its ultimate parent) (a) files for protection under bankruptcy or insolvency laws, (b) makes an assignment for the benefit of creditors, (c) appoints or suffers appointment of a receiver or trustee over substantially all of its property that is not discharged within ninety (90) days after such filing, (d) proposes a written agreement of composition or extension of its debts, (e) proposes or is a party to any dissolution or liquidation, (f) files a petition under any bankruptcy or insolvency act or has any such petition filed against that is not discharged within sixty (60) days of the filing thereof, or (g) admits in writing its inability generally to meet its obligations as they fall due in the general course, then the other Party may terminate this Agreement in its entirety effective immediately upon written notice to such Party.

11.6.1Termination. In the event of (a) a termination of this Agreement in its entirety pursuant to Section 11.2, 11.3, 11.4 or 11.5, (b) in the event of a termination of this Agreement with respect to a Terminated Program pursuant to Section 3.4.1(f) as a result of Regeneron exercising its Lead Party final decision-making authority on the JSC, or (c) termination of this Agreement with respect to a Terminated Program pursuant to Section 4.3.2, in each case ((a)-(c)), the provisions of Schedule 11.6.1 shall apply.

11.6.2Expiration of this Agreement. In the event of expiration of this Agreement, the provisions of Schedule 11.6.1 shall apply.

11.7Remedies. Except as otherwise expressly provided herein, expiration or termination of this Agreement in accordance with the provisions hereof shall not limit remedies that may otherwise be available in law or equity.

11.8Accrued Rights; Surviving Obligations. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued (or that may accrue as a result of activities under this Agreement) to the benefit of a Party prior to such termination or expiration. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated or by their nature are intended to survive the termination or expiration of this Agreement, including this Section 11.8, Sections 2.6, 3.7.1 (for the period set forth therein), 3.7.3, 4.7, 4.10, 5.1.4 (including the last paragraph of Section 5.1 (i.e., unnumbered paragraph beginning with “Notwithstanding”) as applied to Section 5.1.4 only), 5.2.2 (including the last paragraph of Section 5.2 (i.e., unnumbered paragraph beginning with “Notwithstanding”) as applied to Section 5.2.2 only), 5.4, 5.6, clause (O) of 5.7.1(a)(D) (to the extent a given Target is the subject of a License Agreement or Co-Co Collaboration Agreement, as applicable; including any language in such Section 5.7.1(a)(D) to the extent necessary to give effect to such clause (O)), 5.7.1(d) (to the extent a given Target is the subject of a License Agreement or Co-Co Collaboration Agreement, as applicable), 5.8, 6.1 through 6.3 (to the extent such payments have accrued but have not been paid), 6.4.2 (to the extent such payments have accrued but not been paid or to the extent applicable to ongoing Programs under then-existing License Agreements or Co-Co Collaboration Agreements, as applicable), 6.5 (to the extent applicable to ongoing Programs under then-existing License Agreements or Co-Co Collaboration Agreements, as applicable), 6.6, 6.7, 6.8, 6.9, 6.10, 6.11 (for the period set forth therein), 6.12 (for the three (3)-year period following termination or expiration of this Agreement), 6.13, 7.1.1, 7.1.2, 7.1.3, 7.2.6, 7.7, 7.9, 8.1 (for the period set forth therein), 8.2 (for the period set forth in Section 8.1), 8.3, 8.6, 8.7, 9.4, the last sentence of 11.3, 11.6 (including, for clarity, Schedule 11.6.1) and 11.7; ARTICLES 1 (to the extent necessary to interpret the remaining surviving provisions, and including, for clarity, the corresponding schedules, as applicable), 10 and 12; and Schedule 1 and Schedule 2 of this Agreement shall survive the termination or expiration of this Agreement for any reason.

12.1Force Majeure. Neither Party shall be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than an obligation to make payments) when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods, earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts, or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any governmental authority (except to the extent such delay results from the breach by the non-performing Party or any of its Affiliates of any term or condition of this Agreement). The non-performing Party shall notify the other Party of such force majeure within seven (7) Business Days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use commercially reasonable efforts to remedy its inability to perform.

12.2Assignment. Without the prior written consent of the other Party, such consent not to be unreasonably withheld, conditioned or delayed, neither Party shall sell, transfer, assign, delegate, pledge, or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that either Party may make such an assignment without the other Party’s consent to its Affiliate or to a successor, whether in a merger, sale of stock, sale of assets or any other transaction, of all or substantially all of such Party’s business, so long as such Affiliate or Third Party agrees in writing to be bound by the terms of this Agreement. With respect to an assignment to an Affiliate, the assigning Party shall remain responsible for the performance by such Affiliate of the rights and obligations hereunder. Any attempted assignment or delegation in violation of this Section 12.2 shall be void and of no effect. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of Alnylam or Regeneron, as the case may be. In the event either Party seeks and obtains the other Party’s consent to assign or delegate its rights or obligations to another Party, the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement.

12.3Severability. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid, or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid, or unenforceable in any respect.

12.4.1Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. Except for JSC Disputes or Expert Disputes, which are governed by Section 2.2.3 or Schedule 1 respectively, each Party acknowledges and agrees that it must commence any action, suit or proceeding arising out of or in connection with this Agreement (other than appeals therefrom) in the jurisdiction where the other Party is incorporated or has its principal place of business, and each Party hereby waives any objections to such jurisdiction and venue and agrees not to commence any action, suit or proceeding relating to this Agreement except in courts in such jurisdiction. The Parties shall be free to pursue any rights and remedies available to them at law, in equity or otherwise, with respect to any Legal Dispute, subject, however, to this Section 12.4.1 and Section 12.9.

12.4.2Service. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 12.6.2 shall be effective service of process for any action, suit, or proceeding brought against it under this Agreement in any such court.

If a dispute is referred to the Executive Officers, then the Executive Officers shall diligently and in good faith attempt to resolve the referred dispute within thirty (30) days after receiving written notification of such dispute or such longer period of time as the Executive Officers may agree in writing. Any final decision mutually agreed to by the Executive Officers with respect to a dispute and set forth in writing shall be conclusive and binding on the Parties.

No amendment, modification, release, or discharge shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties. If a License Agreement or Co-Co Collaboration Agreement, as applicable, is entered into with respect to a given Program, then to the extent there is a conflict between the provisions of this Agreement and the provisions of such License Agreement or Co-Co Collaboration Agreement, as applicable, the provisions of such License Agreement or Co-Co Collaboration Agreement, as applicable, shall control with respect to such Program (and the Collaboration Target and Collaboration Products thereunder).

12.8LIMITATION OF DAMAGES.

In the event that a Patent Right licensed to Alnylam under an Additional Alnylam In-License actually is or will be infringed by Regeneron’s Development, Manufacture or Commercialization of a Collaboration Product in the Field and in the Territory in accordance with this Agreement, then such Additional Alnylam In-License will thereafter automatically be deemed to be an Existing Alnylam In-License on a Collaboration Product-by-Collaboration Product basis, and all rights granted to Alnylam thereunder will be deemed to be “Controlled” by Alnylam and sublicensed to Regeneron under the applicable terms of Section [6.1]²⁶, effective as of the later of (a) the date the applicable Patent Right issues and (b) the date that Regeneron’s Development, Manufacture or Commercialization of such Collaboration Product in the Field and in the Territory in accordance with this Agreement under the applicable terms of Section [6.1]²⁷ would infringe such Patent Right in the absence of a license thereunder from Alnylam; provided, for clarity, that the performance of activities as permitted under the safe harbor provision provided in 35 U.S.C. § 271(e)(1) (or other applicable safe harbor exemptions in other countries outside the United States) shall not be deemed to trigger the date under the foregoing clause (b).

6.5.3Management of In-Licenses. Neither Party shall, and each Party shall cause its Affiliates not to, enter into any subsequent agreement or understanding with any Third Party to an In-License to which such Party or any of its Affiliates is a party that modifies, amends or terminates any such In-License, or waives any right or obligation thereunder, in any way that would adversely affect in any material respect the other Party’s rights or interests under this Agreement, including by increasing any of the other Party’s obligations or otherwise agreeing to any covenants or obligations imposed on the other Party that would adversely impact the other Party’s business outside of this Agreement, in each case, without the other Party’s prior written consent, not to be unreasonably withheld, conditioned or delayed.

6.5.4In-Licenses. Each Party acknowledges and agrees that the sublicenses and other rights granted by the other Party to such first Party in this Agreement are subject to the terms of any In-Licenses to which such other Party or any of its Affiliates is a party. Each Party granted a sublicense pursuant to this Agreement under any of the In-Licenses of the other Party (or any of its Affiliates) (the Party granted a sublicense, the “Sublicensed Party,” and the Party granting the sublicense, the “Sublicensor Party”) shall comply with, and perform and take such actions as may be required to allow the Sublicensor Party to comply with, all applicable terms and conditions of the In-Licenses of the Sublicensor Party to the extent (a) applicable to (i) the Sublicensed Party’s rights or obligations relating to the Development, Manufacture or Commercialization of Collaboration Products under this Agreement or (ii) the filing, prosecution, maintenance, extension, defense, enforcement or the further sublicensing of the Alnylam Technology (if Alnylam is the Sublicensor Party) or the Regeneron Technology (if Regeneron is the Sublicensor

Party) to the extent relevant to the Sublicensed Party’s rights or obligations relating to the Development, Manufacture or Commercialization of Collaboration Products under this Agreement, and (b) the Sublicensed Party has been given written notice or provided a copy of such terms and conditions on or before the later of (i) the Effective Date and (ii) the date on which such In-License is first required to have been provided to the Sublicensed Party hereunder, including any such terms and conditions relating to sublicensing, patent matters, confidentiality, reporting, audit rights, indemnification and diligence. Without limiting the foregoing, (x) the Parties shall, from time to time, upon the reasonable request of either Party, discuss the terms of any In-License and (y) each Sublicensed Party shall prepare and deliver to the Sublicensor Party any reports required under the applicable In-Licenses of the Sublicensor Party sufficiently in advance to enable the Sublicensor Party to comply with its obligations under the applicable In-Licenses, to the extent that the Sublicensed Party had been made aware of such provisions sufficiently in advance of the date on which such compliance is required in order for such Sublicensed Party to properly prepare such reports.

6.5.5Excluded Agreements. Notwithstanding anything herein to the contrary, Regeneron acknowledges that certain Patent Rights and Information under which Alnylam has rights are in-licensed by Alnylam under the Excluded Agreements. It is understood and agreed that no sublicense is granted to Regeneron by Alnylam under the Excluded Agreements pursuant to this Agreement, and that no Patent Rights or Information licensed to Alnylam under the Excluded Agreements will be Controlled by Alnylam under this Agreement. Alnylam shall be solely responsible for, and shall solely bear, all costs arising under or in connection with any Excluded Agreement.

Each Party shall, if requested to do so by the other Party, promptly enter into confirmatory license agreements in the form or substantially the form reasonably requested by such other Party for purposes of recording the licenses granted under this Agreement with such patent offices in the Territory as the requesting Party considers appropriate. Until the execution of any such confirmatory licenses, so far as may be legally possible, Alnylam and Regeneron shall have the same rights in respect of the respective intellectual property and be under the same obligations to each other in all respects as if the said confirmatory licenses had been executed.

(b)Notwithstanding the provisions of Section 7.1.1(a), the following shall apply:

(i)in the event that a Collaboration Product is a Combination Product that includes a Proprietary Unlicensed Component, then the Parties will not share in any revenues from the Proprietary Unlicensed Component and such revenues shall be solely for the benefit of the Party who has the applicable Proprietary Unlicensed Component (provided that with respect to Net Sales, the Parties agree that such allocation shall be in accordance with the definition of Net Sales), and the Parties shall in good faith reasonably allocate and share in accordance with the terms of this Agreement the revenues attributable to the Collaboration Product other than the Proprietary Unlicensed Component of such Collaboration Product; and

(ii)in the event that a Proprietary Unlicensed Component is administered in a Clinical Trial of Collaboration Product hereunder, then [***].

(c)Notwithstanding the provisions of Section 7.1.1(a), solely with respect to the Ongoing Candidate Discovery Development Activities, the Party that is responsible for performing such activities (as set forth in the Pre-Clinical Plan and Budget) shall be solely responsible for the costs thereof, and such costs shall not be included as Development Costs hereunder and shall not be shared by the Parties.

7.1.4Recoupment of Excess Development and Commercialization Costs. Subject to Section 7.1.5:

(a)If, with respect to a Calendar Quarter, after the First Commercial Sale of any Collaboration Product in the Territory, the Profits in such Calendar Quarter are a positive number and the Lead Party is the Party owing a Quarterly Profit True-Up payment:

(i)if the Lead Party has any remaining Recoupment Balance, it shall be permitted to reduce such Quarterly Profit True-Up payment by an amount equal to its current Recoupment Balance; provided that if the Lead Party’s current Recoupment Balance is greater than the amount of such Quarterly Profit True-Up payment, then such Quarterly Profit True-Up payment shall not be reduced below zero; and

(ii)if the Participating Party has any remaining Recoupment Balance, the Lead Party shall increase such Quarterly Profit True-Up payment by an amount equal to the Participating Party’s current Recoupment Balance.

7.2.1Royalties. From and after the First Commercial Sale of a Collaboration Product in a country, for each Calendar Quarter during the applicable Royalty Term for such Collaboration Product in such country, the Lead Party shall make royalty payments to the Participating Party on aggregate worldwide annual Net Sales of such Collaboration Product, on a Collaboration Product-by-Collaboration Product basis, at the following royalty rates (the “Royalties”):

(a)If the Opt-Out Party exercises its Opt-Out Right prior to the Phase 2 Completion Date:

(b)If the Opt-Out Party exercises its Opt-Out Right after the Phase 2 Completion Date:

If the Opt-Out Party exercises its Opt-Out Right after the First Commercial Sale of a Collaboration Product in the first Major Market Country, the Parties shall negotiate in good faith whether to change (and if so, the change to) the royalty rates in this Section 7.2.1(b) based on the Opt-Out Party’s contribution to the Development and Regulatory Approval of the Collaboration Products, the status of the Collaboration Products and the commercial prospects for the Collaboration Products.

7.2.2Royalty Rate Reductions. Notwithstanding the provisions of Section 7.2.1, if during the Royalty Term for a Collaboration Product in a country:

(d)Schedule 7.2.6 sets forth example applications of Section 7.2.6(a) through Section 7.2.6(c).

7.2.8Royalty Reports. Within [***] days following the end of each Calendar Quarter, commencing with the Calendar Quarter in which the First Commercial Sale of any Collaboration Product occurs in any country, (a) the Lead Party shall provide to the Participating Party a written report (in electronic form) setting forth, for such Calendar Quarter, (i) the Net Sales of each Collaboration Product, (ii) Collaboration Product quantities sold, (iii) gross Collaboration Product sales and a reasonably detailed accounting of the deductions from gross sales permitted by the definition of Net Sales and (iv) the amount of any In-License Payments paid by the Lead Party or any of its Affiliates and (b) the Participating Party shall provide to the Lead Party a written report (in electronic form) setting forth, for such Calendar Quarter, the amount of any In-License Payments paid by the Participating Party or any of its Affiliates.

7.4Invoices and Documentation. The JFC shall approve the form of any necessary documentation relating to any Development Costs, Profit Split, Royalty or other payments hereunder so as to afford the Parties appropriate accounting treatment in relation to any of the transactions or payments contemplated hereunder.

7.5Payment Method and Currency. All payments under this Agreement shall be made by bank wire transfer in immediately available funds to an account designated by the Party to which such payments are due. All sums due under this Agreement shall be payable in Dollars. In those cases where the amount due in Dollars is calculated based upon one or more currencies other than Dollars, such amounts shall be converted to Dollars at the average rate of exchange for the Calendar Quarter to which such payment relates using the arithmetic mean of the daily rate of exchange, as reported in Thomson Reuters Eikon (or any successor thereto) or any other source as agreed to by the Parties.

7.6Taxes. Either Party may withhold from payments due to the other 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. In such case, the payor Party will provide the payee Party all relevant documents and correspondence, and will also provide to the payee Party any other cooperation or assistance on a commercially reasonable basis as may be necessary to enable the payee Party to claim exemption from such withholding taxes and to receive a refund of such withholding tax or claim a foreign tax credit. The payor 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. Apart from any withholding permitted under this Section 7.6 and those deductions expressly included in the definition of Net Sales, the amounts payable hereunder will not be reduced on account of any taxes, charges, duties or other levies. Notwithstanding the foregoing, if, as a result of a Withholding Action by the paying Party (including any assignee or successor), any withholding or deduction of or on account of taxes, duties, levies, imposts, assessments, deductions, fees and other similar charges (“Withholding”) is required by Applicable Law and the amount of such Withholding exceeds the amount of Withholding that would have been required if the paying Party had not committed the Withholding Action, then the paying Party shall pay an additional amount to the receiving Party such that, after Withholding from the payment and such additional amount, the receiving Party receives the same amount as it would have received from the paying Party absent such Withholding Action by the paying Party. For the avoidance of doubt, if as a result of a Withholding Action by a receiving Party (including any assignee or successor) the amount of Withholding under the law of the applicable jurisdiction exceeds the amount of such Withholding that would been required in the absence of such Withholding Action by the receiving Party, the paying Party shall be required to pay any additional amount only to the extent that the

paying Party would be required to pay any additional amount to the receiving Party pursuant to the preceding sentence if the receiving Party had not committed such Withholding Action. For purposes of this Section 7.6, “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 to become subject to tax in a jurisdiction outside of the United States or subject any payments to Withholding in any jurisdiction that would not have been required absent such Withholding Action.

7.7Resolution of Payment Disputes. In the event there is a dispute relating to any payment obligations or reports hereunder, the Party with the dispute shall have its representative on the JFC provide the other Party’s representative on the JFC with written notice setting forth in reasonable detail the nature and factual basis for such good faith dispute and the Parties, through the JFC, will seek to resolve the dispute as promptly as possible, but no later than ten (10) days after such written notice is received. If the JFC is unable to resolve such payment dispute within such period then the matter shall be referred to the JSC. The Parties agree that if there is a dispute regarding any payment amount, only the disputed amount shall be withheld from the payment, and the undisputed amount shall be paid within the applicable timeframes.

7.8Late Fee. A late fee [***] as reported on Thomson Reuters Eikon (or any successor thereto) (or another source agreed to by the Parties) on the date that the applicable payment was due may be charged by the Party to whom payment is due with respect to any payment amount from the date such payment amount was originally due under the terms of this Agreement until such payment amount is actually paid by one Party to another Party unless such payment amount is disputed pursuant to Section 7.7, in which case the foregoing late fee shall commence on the date such dispute is resolved.

7.9Books and Records. Each Party shall (a) keep proper books of record and account in which full, true and correct entries (in conformity with Accounting Standards) shall be made for the purpose of determining the amounts payable or owed pursuant to this Agreement; (b) keep such books of record and account for at least [***] Calendar Years following the Calendar Year to which they pertain (or such longer period to the extent required by Applicable Law) and (c) keep such books of record and account to the extent related to this Agreement in a readily available and organized form to allow an independent auditor to verify the accuracy of all financial, accounting and numerical information provided in an efficient manner. To the extent a Party is not in compliance with clause (c) of this Section 7.9, such Party shall be responsible for any additional fees charged by the independent auditor to the other Party as a result of additional time spent by the independent auditor assembling or organizing such information.

7.10.1Audit. Each Party shall have the right, upon no less than [***] advance written notice and at such reasonable places, times and intervals and to such reasonable extent as such Party shall request, not more than once during any Calendar Year, to have the books of record and account of the other Party to the extent relating to this Agreement for the preceding [***] Calendar Years audited by an independent and nationally recognized accounting firm of its choosing and reasonably acceptable to the other Party, for the sole purpose of verifying the accuracy of all financial, accounting and numerical information and calculations provided, and payments made, under this Agreement; provided, that absent evidence of fraud, gross negligence or willful misconduct no period may be subjected to audit more than [***].

7.10.2Results; Costs; Confidentiality. The results of any such audit shall be delivered in writing to each Party and shall be final and binding upon the Parties, unless disputed by a Party by notice to the other Party within [***] days after delivery. [***] Such accountants shall not reveal to the Party requesting the audit the details of its review, except for the results of such review and such information as is required to be disclosed under this Agreement, and shall be subject to the confidentiality provisions contained in ARTICLE 9. At the request of the Party being audited prior to the audit, the auditing Party shall cause its accounting firm to enter into a reasonably acceptable confidentiality agreement with the audited Party obligating such accounting firm to retain all such information in confidence pursuant to such confidentiality agreement.

7.10.3Reconciliation. If any examination or audit of the records described above discloses an overbilling or underpayment of amounts due hereunder, then unless the result of the audit is contested pursuant to Section 7.10.2, the Party that over-billed or underpaid shall pay the same to the Party entitled thereto within thirty (30) days after receipt of the written results of such audit pursuant to Section 7.10.1.

7.10.4Binding and Conclusive. Upon the expiration of the three (3) year period following the end of any Calendar Year, the calculation of the amounts payable with respect to such Calendar Year shall be binding and conclusive upon the Parties.

7.11Accounting Standards. Except as otherwise provided herein, all costs and expenses and other financial determinations with respect to this Agreement shall be determined in accordance with Accounting Standards, as generally and consistently applied.

If the Breaching Party does not dispute that it has committed such a material breach under this Agreement, the Supply Agreement (if any) or the Quality Agreement (if any) that results in the Non-Breaching Party having a right to terminate this Agreement, then if the Breaching Party fails to cure such breach, or fails to take steps as would be considered reasonable to effectively cure such breach, within ninety (90) days after receipt of the Default Notice, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party. If the Breaching Party disputes that it has committed a material breach under this Agreement, the Supply Agreement (if any) or the Quality Agreement (if any) that results in the Non-Breaching Party having a right to terminate this Agreement, the dispute shall be resolved pursuant to

Section 13.5. If, as a result of the application of such dispute resolution procedures, the Breaching Party is determined to have materially breached in a manner that fundamentally frustrates the value or essential characteristics of the transactions contemplated by this Agreement (an “Adverse Ruling”), then if the Breaching Party fails to complete the actions specified by the Adverse Ruling to cure such material breach within ninety (90) days after such ruling, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party; provided that if such compliance cannot be fully achieved within such ninety (90)-day cure period, then such cure period will be extended for a period of up to sixty (60) additional days (for a total cure period of one hundred fifty (150) days) if the Breaching Party prepares and provides to the Non-Breaching Party a reasonable written plan for curing such material breach and uses commercially reasonable efforts to cure such material breach in accordance with such written plan, and if such material breach is not cured within such one hundred fifty (150)-day period, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party.

12.5Additional Lead Party Termination Right. If a Party exercises its Opt-Out Right, and thereafter, the Lead Party (which may be the New Lead Party, if applicable), desires to terminate its obligations with respect to Development and Commercialization of the Collaboration Products, it shall so notify the Participating Party and thereafter: (a) the Lead Party’s obligation to use Commercially Reasonable Efforts to Develop and Commercialize Collaboration Products shall terminate, (b) each Party’s obligations under Section 6.7.1 shall terminate, (c) the Parties shall cooperate in good faith to license, sell or otherwise grant or transfer to a Third Party the right to further Develop or Commercialize the Collaboration Products (but excluding any Proprietary Unlicensed Components); provided that the Lead Party shall control the process of licensing, selling or otherwise granting or transferring such right to further Develop or Commercialize the Collaboration Products and shall have final say with respect to entering into a transaction with a Third Party with respect thereto, and (d) the Parties shall share the proceeds of any such transaction as if they were Third Party Transaction Proceeds at the Third Party Transaction Proceeds Percentage and negotiate in good faith the terms of termination of this Agreement to accommodate any such transaction.

13.1Force Majeure. Neither Party shall be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than an obligation to make payments) when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods, earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, riots, civil commotion, strikes, lockouts, or other labor disturbances (whether involving the workforce of the non-performing Party or of any other Person), acts of God or acts, omissions or delays in acting by any governmental authority (except to the extent such delay results from the breach by the non-performing Party or any of its Affiliates of any term or condition of this Agreement). The non-performing Party shall notify the other Party of such force majeure within seven (7) Business Days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use commercially reasonable efforts to remedy its inability to perform.

13.2Assignment. Without the prior written consent of the other Party, such consent not to be unreasonably withheld, conditioned or delayed, neither Party shall sell, transfer, assign, delegate, pledge, or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that either Party may make such an assignment without the other Party’s consent to its Affiliate or to a successor, whether in a merger, sale of stock, sale of assets or any other transaction, of all or substantially all of such Party’s business, so long as such Affiliate or Third Party agrees in writing to be bound by the terms of this Agreement. With respect to an assignment to an Affiliate, the assigning Party shall remain responsible for the performance by such Affiliate of the rights and obligations hereunder. Any attempted assignment or delegation in violation of this Section 13.2 shall be void and of no effect. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of Alnylam or Regeneron, as the case may be. In the event either Party seeks and obtains the other Party’s consent to assign or delegate its rights or obligations to another Party, the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement.

13.3Severability. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under any present or future law, and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (a) such provision shall be fully severable, (b) this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid, or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render any provision hereof illegal, invalid, or unenforceable in any respect.

13.4.1Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

The Parties shall be free to pursue any rights and remedies available to them at law, in equity or otherwise, with respect to any Legal Dispute, subject, however, to this Section 13.4.1 and Section 13.9.

13.4.2Service. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 13.6.2 shall be effective service of process for any action, suit, or proceeding brought against it under this Agreement in any such court.

13.5.2Either Party may require that any dispute, other than JSC Disputes (which are governed by Section 2.6.3), Expedited Matters (which are governed by Schedule 1 and are referred to Executive Officers pursuant to the terms thereof) and Expert Disputes (which are governed by Schedule 2), be submitted to the Executive Officers for resolution by providing written notice to the other Party formally requesting that the dispute be resolved by the Executive Officers and specifying the nature of the dispute with sufficient specificity to permit adequate consideration by such Executive Officers. If a dispute is referred to the Executive Officers, then the Executive Officers shall diligently and in good faith attempt to resolve the referred dispute within thirty (30) days after receiving written notification of such dispute or such longer period of time as the Executive Officers may agree in writing. Any final decision mutually agreed to by the Executive Officers with respect to a dispute and set forth in writing shall be conclusive and binding on the Parties. If the Executive Officers cannot resolve such dispute within such thirty (30) days or such other period as agreed by the Executive Officers, such dispute will be resolved as follows:

(a)with respect to any Financial Dispute, such Financial Dispute shall be submitted for resolution to a certified public accounting firm jointly selected by each Party’s certified public accountants or to such other Person as the Parties shall mutually agree (the “Financial Expert”). The decision of the Financial Expert shall be final and the costs of the Financial Expert shall be borne by the Parties in accordance with such allocation as the Financial Expert shall determine;

(b)with respect to any Expedited Matter, such Expedited Matter shall be resolved pursuant to the provisions of Schedule 1;

(c)with respect to any Expert Dispute, such Expert Dispute shall be resolved pursuant to the provisions of Schedule 2; and

(d)with respect to all other disputes (but, for clarity, excluding JSC Disputes), including Legal Disputes, the Parties shall be free to pursue any rights and remedies available to them at law, in equity or otherwise subject, however, to Section 13.4.1 and Section 13.9.

13.6.1Notice Requirements. All notices, instructions and other communications required or permitted hereunder or in connection herewith shall be in writing, shall be sent to the address of the relevant Party set forth at its address specified in Section 13.6.2 and shall be (a) delivered personally, or (b) sent via a reputable international overnight courier service. Any such notice, instruction or communication shall be deemed to have been delivered upon receipt if delivered by hand or one (1) Business Day after it is sent via a reputable international overnight courier service. Either Party may change its address by giving notice to the other Party in the manner provided above. This Section 13.6.1 is not intended to govern the day-to-day business communications necessary between the Parties in performing their obligations under the terms of this Agreement.

13.7.1This Agreement, the Supply Agreement (if any) and the Quality Agreement (if any), and the Master Agreement, together with the schedules attached hereto and thereto, sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and all prior agreements, understandings, promises, and representations, whether written or oral, with respect thereto are superseded hereby. Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth in this Agreement, the Supply Agreement (if any) and the Quality Agreement (if any), or the Master Agreement. In the event of a conflict between the provisions of this Agreement and the Master Agreement with respect to the Target Program (or the Target or Collaboration Products thereunder), the provisions of this Agreement shall control. For the avoidance of doubt, the Parties agree and acknowledge that from and after the Effective Date, there shall be no additional Development, Manufacturing or Commercialization activities with respect to the Target Program or the Exploitation of Collaboration Products pursuant to the Master Agreement.

13.7.2No amendment, modification, release, or discharge shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties.

13.8LIMITATION OF DAMAGES. IN NO EVENT SHALL REGENERON OR ALNYLAM BE LIABLE FOR SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING, LOSS OF PROFITS) SUFFERED BY THE OTHER PARTY, REGARDLESS OF THE THEORY OF LIABILITY (INCLUDING CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE) AND REGARDLESS OF ANY PRIOR NOTICE OF SUCH DAMAGES. HOWEVER, NOTHING IN THIS SECTION 13.8 IS INTENDED TO LIMIT OR RESTRICT (A) LIABILITY FOR BREACH OF SECTION 6.7.1 OR ARTICLE 9 OR (B) THE INDEMNIFICATION RIGHTS AND OBLIGATIONS OF EITHER PARTY HEREUNDER AS SET FORTH IN SECTION 11.1 WITH RESPECT TO CLAIMS.

13.9.1Each Party acknowledges and agrees that the restrictions set forth in Section 6.7 and ARTICLE 9 are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of such Section or Article may result in irreparable injury to such other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of such Section or Articles, the non-breaching Party shall be authorized and entitled to seek from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance, and an equitable accounting of all earnings, profits, and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity.

13.9.3Each Party hereby waives any requirement that the other Party, as a condition for obtaining any such relief (a) post a bond or other security or (b) show irreparable harm, balancing of harms, consideration of the public interest, or inadequacy of monetary damages as a remedy. Nothing in this Section 13.9 is intended, or should be construed, to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement.

13.10Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party whether of a similar nature or otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth herein.

13.11No Benefit to Third Parties. The covenants and agreements set forth in this Agreement are for the sole benefit of the Parties and their successors and permitted assigns, and they shall not be construed as conferring any rights on any other Persons.

13.12Further Assurance. Each Party shall 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 assignments, agreements, documents, and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes hereof, or to better assure and confirm unto such other Party its rights and remedies under this Agreement.

13.13Relationship of the Parties. It is expressly agreed that Alnylam, on the one hand, and Regeneron, on the other hand, shall be independent contractors and that the relationship between the two (2) Parties shall not constitute a partnership, joint venture, or agency. Neither Alnylam, on the one hand, nor Regeneron, on the other hand, shall have the authority to make any statements, representations, or commitments of any kind, or to take any action, which shall be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such Party.

13.14Counterparts; Facsimile Execution. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may be executed by facsimile or electronically transmitted signatures and such signatures shall be deemed to bind each Party as if they were original signatures.

13.15References. Unless otherwise specified, (a) references in this Agreement to any Article, Section or schedule shall mean references to such Article, Section or schedule of this Agreement, (b) references in any Section to any clause are references to such clause of such Section, and (c) references to any agreement, instrument, or other document in this Agreement refer to such agreement, instrument, or other document as originally executed or, if subsequently amended, replaced, or supplemented from time to time, as so amended, replaced, or supplemented and in effect at the relevant time of reference thereto.

13.16Schedules. In the event of any inconsistencies between this Agreement and any schedules or other attachments hereto, the terms of this Agreement shall control.

13.17Construction. Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural the singular, the use of any gender shall be applicable to all genders and the word “or” is used in the inclusive sense (and/or). Whenever this Agreement refers to a number of days, unless otherwise specified, such number refers to calendar days. The captions of this Agreement are for convenience of reference only and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The term “including,” “include,” or “includes” as used herein shall mean including, without limiting the generality of any description preceding such term. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party.

THIS AGREEMENT IS EXECUTED by the authorized representatives of the Parties as of the Effective Date.

From and after the First Commercial Sale of a Collaboration Product in a country, for each Calendar Quarter during the applicable Royalty Term for such Collaboration Product in such country, Licensee shall make royalty payments to Licensor on aggregate worldwide annual Net Sales of such Collaboration Product, on a Collaboration Product-by-Collaboration Product basis, at the following royalty rates (the “Royalties”):

7.1.2Royalty Rate Reductions. Notwithstanding the provisions of Section 7.1.1, if during the Royalty Term for a Collaboration Product in a country:

7.1.3 [Manufacturing Technology Transfer Costs Reduction. Subject to Section 7.1.5, [***]

7.1.6Royalty Reports. Within [***] days following the end of each Calendar Quarter, commencing with the Calendar Quarter in which the First Commercial Sale of any Collaboration Product occurs in any country, (a) Licensee shall provide to Licensor a written report (in electronic form) setting forth, for such Calendar Quarter, (i) the Net Sales of each Collaboration Product, (ii) Collaboration Product quantities sold, (iii) gross Collaboration Product sales and a

reasonably detailed accounting of the deductions from gross sales permitted by the definition of Net Sales and (iv) the amount of any In-License Payments paid by Licensee or any of its Affiliates and (b) Licensor shall provide to Licensee a written report (in electronic form) setting forth, for such Calendar Quarter, the amount of any In-License Payments paid by Licensor or any of its Affiliates. Within [***] days following the end of each Calendar Quarter, Licensee shall deliver the Royalties payment, if any, due to Licensor under Section 7.1.1 for the applicable Calendar Quarter. Such reports shall be broken down on a country-by-country basis with respect to the Major Market Countries and Licensee shall report the other countries of the Territory in a consolidated manner.

7.1.7Unlicensed Components. For clarity, the Parties shall not share any revenues from any Unlicensed Component of a Collaboration Product, either through sharing of Third Party Transaction Proceeds, or payment of royalties or milestones, or otherwise (provided that with respect to Net Sales, the Parties agree that any allocation shall be in accordance with the definition of Net Sales).

7.2.1Development and Commercialization Milestones. Subject to the terms of this Section 7.2, Licensee will notify Licensor promptly (but in all cases within thirty (30) days) following the first achievement by Licensee under this Agreement of each milestone event described below in this 7.2.1 with respect to a given New Collaboration Product to achieve such milestone event, and Licensee shall thereafter pay the applicable amounts set forth below associated with the applicable milestone event in accordance with Section 7.2.3 (each, a “Non-Rare Disease Milestone Payment”):

Each of the foregoing Milestone Payments in this Section 7.2.1 shall be payable a maximum of one (1) time for a given New Collaboration Product as set forth in the foregoing chart (i.e., a maximum of seven (7) Milestone Payments may be made pursuant to this Section 7.2.1 for a given New Collaboration Product), and no additional Milestone Payments shall be due hereunder for subsequent or repeated achievement of such milestone event for a given New Collaboration Product. For the avoidance of doubt, (i) the maximum amount payable by Licensee pursuant to this Section 7.2.1 for a given New Collaboration Product is [***], assuming that each of the milestone events in this Section 7.2.1 are achieved for such New Collaboration Product and (ii) no Milestone Payments shall be payable for any Collaboration Product that is not a New Collaboration Product.

7.2.2Rare Disease Milestones. Subject to the terms of this Section 7.2 and notwithstanding Section 7.2.1, in the event a given New Collaboration Product is being Developed for a Rare Disease (a “Rare Disease New Collaboration Product”), in lieu of the Milestone Payments set forth in Section 7.2.1, Licensee will pay Licensor for achievement of the milestones set forth in this Section 7.2.2. Licensee will notify Licensor promptly (but in all cases within thirty (30) days) following the first achievement by Licensee under this Agreement of each milestone event described below in this Section 7.2.2 with respect to a given Rare Disease New Collaboration Product to achieve such milestone event, and Licensee shall thereafter pay the applicable amounts set forth below associated with the applicable milestone event in accordance with Section 7.2.3 (each, a “Rare Disease Milestone Payment”):

Each of the foregoing Milestone Payments in this Section 7.2.2 shall be payable a maximum of one (1) time for a given Rare Disease New Collaboration Product as set forth in the foregoing chart (i.e., a maximum of two (2) Milestone Payments may be made pursuant to this Section 7.2.2 for a given Rare Disease New Collaboration Product), and no additional Rare Disease Milestone Payments shall be due hereunder for subsequent or repeated achievement of such milestone event for a given Rare Disease New Collaboration Product. For the avoidance of doubt, (i) the maximum amount payable by Licensee pursuant to this Section 7.2.2 for a given Rare Disease New Collaboration Product is [***], assuming that each of the milestone events in this Section 7.2.2 are achieved and (ii) no Milestone Payments shall be payable for any Collaboration Product that is not a Rare Disease New Collaboration Product.

7.2.3Notwithstanding the foregoing, if a New Collaboration Product is a Rare Disease New Collaboration Product but is also Developed for a non-Rare Disease, and prior to the achievement of any of the Rare Disease Milestone Payment events with respect to such Rare Disease New Collaboration Product, a Development Milestone Event is achieved under Section 7.2.1 with respect to such Rare Disease New Collaboration Product for such non-Rare Disease, then such New Collaboration Product shall be subject to the provisions of Section 7.2.1 and not this Section 7.2.2. In such case, at the time that such New Collaboration Product achieves the first Development Milestone Event for which a Milestone Payment is payable pursuant to Section 7.2.1, Licensee shall also be deemed to have achieved any earlier Development Milestone Events pursuant to Section 7.2.1 for which Development Milestones were not previously paid with respect to such New Collaboration Product (e.g., if the first Development Milestone that is achieved for such Collaboration Product for a non-Rare Disease is [***], then each of Development Milestones #1 and #2 from Section 7.2.1 will be deemed achieved by Licensee at the such time).

7.2.4Invoice and Payment of Milestone Payments. Following receipt of notification by Licensee to Licensor that Licensee has achieved the applicable milestone event triggering a milestone payment pursuant to Section 7.2.1 or 7.2.2, as applicable, Licensor shall invoice Licensee for the applicable milestone payment, and, subject to Section 7.10, Licensee shall pay each milestone payment [***] days after receipt of the invoice therefor.

7.2.5One-Time Only Payments. For clarity, a given Collaboration Product shall only be eligible for milestone payments under one of Section 7.2.1 or 7.2.2, but not both.

7.6No Double Counting. Notwithstanding anything to the contrary contained herein, no cost or expense shall be included as an Alnylam Specific Activities Costs (or any component thereof) or in the calculation of Net Sales (or any component thereof), if inclusion therein would result in a duplication or double-counting of the same cost or expense, either hereunder or under the Master Agreement or any other License Agreement or Co-Co Collaboration Agreement.

7.7Invoices and Documentation. The Parties shall approve the form of any necessary documentation relating to any Royalty, milestone or other payments hereunder so as to afford the Parties appropriate accounting treatment in relation to any of the transactions or payments contemplated hereunder. Unless otherwise agreed by the Parties, the financial data in the reports will include calculations in local currency and Dollars.

7.8Payment Method and Currency. All payments under this Agreement shall be made by bank wire transfer in immediately available funds to an account designated by the Party to which such payments are due. All sums due under this Agreement shall be payable in Dollars. In those cases where the amount due in Dollars is calculated based upon one or more currencies other than Dollars, such amounts shall be converted to Dollars at the average rate of exchange for the Calendar Quarter to which such payment relates using the arithmetic mean of the daily rate of exchange, as reported in Thomson Reuters Eikon (or any successor thereto) or any other source as agreed to by the Parties.

7.9Taxes. Either Party may withhold from payments due to the other 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. In such case, the payor Party will provide the payee Party all relevant documents and correspondence, and will also provide to the payee Party any other cooperation or assistance on a commercially reasonable basis as may be necessary to enable the payee Party to claim exemption from such withholding taxes and to receive a refund of such withholding tax or claim a foreign tax credit. The payor 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. Apart from any withholding permitted under this Section 7.9 and those deductions expressly

included in the definition of Net Sales, the amounts payable hereunder will not be reduced on account of any taxes, charges, duties or other levies. Notwithstanding the foregoing, if, as a result of a Withholding Action by the paying Party (including any assignee or successor), any withholding or deduction of or on account of taxes, duties, levies, imposts, assessments, deductions, fees and other similar charges (“Withholding”) is required by Applicable Law and the amount of such Withholding exceeds the amount of Withholding that would have been required if the paying Party had not committed the Withholding Action, then the paying Party shall pay an additional amount to the receiving Party such that, after Withholding from the payment and such additional amount, the receiving Party receives the same amount as it would have received from the paying Party absent such Withholding Action by the paying Party. For the avoidance of doubt, if as a result of a Withholding Action by a receiving Party (including any assignee or successor) the amount of Withholding under the law of the applicable jurisdiction exceeds the amount of such Withholding that would been required in the absence of such Withholding Action by the receiving Party, the paying Party shall be required to pay any additional amount only to the extent that the paying Party would be required to pay any additional amount to the receiving Party pursuant to the preceding sentence if the receiving Party had not committed such Withholding Action. For purposes of this Section 7.9, “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 to become subject to tax in a jurisdiction outside of the United States or subject any payments to Withholding in any jurisdiction that would not have been required absent such Withholding Action.

7.10Resolution of Payment Disputes. In the event there is a dispute relating to any payment obligations or reports hereunder, the Party with the dispute shall provide the other Party with written notice setting forth in reasonable detail the nature and factual basis for such good faith dispute and the Parties will seek to resolve the dispute as promptly as possible, but no later than ten (10) days after such written notice is received. If the Parties are unable to resolve such payment dispute within such period then the matter shall be resolved pursuant to Section 13.5. The Parties agree that if there is a dispute regarding any payment amount, only the disputed amount shall be withheld from the payment, and the undisputed amount shall be paid within the applicable timeframes.

7.11Late Fee. A late fee [***] as reported on Thomson Reuters Eikon (or any successor thereto) (or another source agreed to by the Parties) on the date that the applicable payment was due may be charged by the Party to whom payment is due with respect to any payment amount from the date such payment amount was originally due under the terms of this Agreement until such payment amount is actually paid by one Party to another Party unless such payment amount is disputed pursuant to Section 7.10, in which case the foregoing late fee shall commence on the date such dispute is resolved.

7.12Books and Records. Each Party shall (a) keep proper books of record and account in which full, true and correct entries (in conformity with Accounting Standards) shall be made for the purpose of determining the amounts payable or owed pursuant to this Agreement; (b) keep such books of record and account for at least [***] Calendar Years following the Calendar Year to which they pertain (or such longer period to the extent required by Applicable Law) and (c) keep such books of record and account to the extent related to this Agreement in a readily available and organized form to allow an independent auditor to verify the accuracy of all financial, accounting and numerical information provided in an efficient manner. To the extent a Party is not in compliance with clause (c) of this Section 7.12, such Party shall be responsible for any additional fees charged by the independent auditor to the other Party as a result of additional time spent by the independent auditor assembling or organizing such information.

7.13.1Audit. Each Party shall have the right, upon no less than [***] days’ advance written notice and at such reasonable places, times and intervals and to such reasonable extent as such Party shall request, not more than once during any Calendar Year, to have the books of record and account of the other Party to the extent relating to this Agreement for the preceding [***] Calendar Years audited by an independent and nationally recognized accounting firm of its choosing and reasonably acceptable to the other Party, for the sole purpose of verifying the accuracy of all financial, accounting and numerical information and calculations provided, and payments made, under this Agreement; provided, that absent evidence of fraud, gross negligence or willful misconduct no period may be subjected to audit more than [***] time.

7.13.2Results; Costs; Confidentiality. The results of any such audit shall be delivered in writing to each Party and shall be final and binding upon the Parties, unless disputed by a Party by notice to the other Party within [***] days after delivery. [***] Such accountants shall not reveal to the Party requesting the audit the details of its review, except for the results of such review and such information as is required to be disclosed under this Agreement, and shall be subject to the confidentiality provisions contained in ARTICLE 9. At the request of the Party being audited prior to the audit, the auditing Party shall cause its accounting firm to enter into a reasonably acceptable confidentiality agreement with the audited Party obligating such accounting firm to retain all such information in confidence pursuant to such confidentiality agreement.

7.13.3Reconciliation. If any examination or audit of the records described above discloses an overbilling or underpayment of amounts due hereunder, then unless the result of the audit is contested pursuant to Section 7.13.2, the Party that over-billed or underpaid shall pay the same to the Party entitled thereto within thirty (30) days after receipt of the written results of such audit pursuant to Section 7.13.1.

7.13.4Binding and Conclusive. Upon the expiration of the three (3) year period following the end of any Calendar Year, the calculation of the amounts payable with respect to such Calendar Year shall be binding and conclusive upon the Parties.

7.14Accounting Standards. Except as otherwise provided herein, all costs and expenses and other financial determinations with respect to this Agreement shall be determined in accordance with Accounting Standards, as generally and consistently applied.

Neither Party shall issue any other public announcement, press release, or other public disclosure regarding this Agreement or its subject matter without the other Party’s prior written consent, except for any such disclosure that is, in the opinion of the disclosing Party’s counsel, required by Applicable Law or the rules of a stock exchange on which the securities of the disclosing Party are listed (or to which an application for listing has been submitted) and except that a Party may, once a press release or other public written statement is approved in writing by both Parties, make subsequent public disclosure of the information contained in such press release or other public written statement without the further approval of the other Party. In the event a Party is, in the opinion of its counsel, required by Applicable Law or the rules of a stock exchange on which its securities are listed (or to which an application for listing has been submitted) to make such a public disclosure, such Party shall submit the proposed disclosure in writing to the other Party as far in advance as reasonably practicable (and in no event less than [***] Business Days prior to the anticipated date of disclosure) so as to provide a reasonable opportunity to comment thereon. Notwithstanding the foregoing, Licensee, its Affiliates and its and their Sublicensees shall have the right to publicly disclose research, development and commercial information (including with respect to regulatory matters) regarding any Collaboration Product; provided (a) such disclosure is subject to the provisions of this ARTICLE 9 with respect to Licensor’s Confidential Information and (b) Licensee shall not use the name of Licensor (or insignia, or any contraction, abbreviation or adaptation thereof) without Licensor’s prior written permission.

Prior to making any public disclosure, to the extent practicable, Licensee shall provide Licensor with a draft of such proposed disclosure for Licensor’s review and comment, which shall be considered in good faith by Licensee. Such draft shall be provided to Licensor at least [***] day (or, to the extent faster timely disclosure of a material event is required by Applicable Law or stock exchange or stock market rules, such shorter period of time sufficiently in advance of the disclosure so that Licensor will have the opportunity to comment upon the disclosure and Licensee will be able to comply with its obligations as required by Applicable Law or stock exchange or stock market rules) prior to making any such disclosure, for Licensor’s review and comment, which shall be considered in good faith by Licensee. Without limiting the foregoing, the Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement with the United States Securities and Exchange Commission or its equivalent in the Territory. Each Party shall be entitled to make such filings, except that the Parties shall cooperate with each other and use reasonable efforts to obtain confidential treatment of confidential, including trade secret, information in accordance with Applicable Law. The filing Party shall provide the non-filing Party with an advance copy of this Agreement marked to show provisions for which the filing Party intends to seek confidential treatment and shall reasonably consider the non-filing Party’s timely comments thereon and cooperate with such non-filing Party in seeking such confidential treatment and, upon the written request of the non-filing Party, shall request an appropriate extension of the term of the confidential treatment period.

If Licensor informs Licensee that such publication, in Licensor’s reasonable judgment, could be expected to have a material adverse effect on any patentable invention owned by or licensed, in whole or in part, to Licensor, or on any Information that is Confidential Information of Licensor, Licensee shall delay or prevent such publication as follows: (i) with respect to a patentable invention, such publication shall be delayed sufficiently long (not to exceed [***] days) to permit the timely preparation and filing of a patent application; and (ii) with respect to Information that is Confidential Information of such Licensor (other than the results of a Clinical Trial or any Product Regulatory Information), such Information shall be deleted from the publication. Licensee will also consider in good faith any other comments of Licensor. Any publication shall include recognition of the contributions of Licensor according to standard practice for assigning scientific credit, either through authorship or acknowledgement, as may be appropriate.

9.6Return of Confidential Information. Upon the effective date of the expiration pursuant to Section 12.1 or termination of this Agreement for any reason, either Party may request in writing, and the other Party shall either, with respect to Confidential Information to which such other Party does not retain rights under the surviving provisions of this Agreement: (a) promptly destroy all copies of such Confidential Information in the possession of the other Party and confirm such destruction in writing to the requesting Party; or (b) promptly deliver to the requesting Party, at the other Party’s expense, all copies of such Confidential Information in the possession of the other Party; provided, however, the other Party shall be permitted to retain one (1) copy of such Confidential Information for the sole purpose of performing any continuing obligations hereunder or for archival purposes. Notwithstanding the foregoing, such other Party also shall be permitted to retain such additional copies of or any computer records or files containing such Confidential Information that have been created solely by such Party’s automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with such other Party’s standard archiving and back-up procedures, but not for any other use or purpose. All Confidential Information shall continue to be subject to the terms of this Agreement for the period set forth in Section 9.1.

9.7Confidential Information that Relates to Multiple Programs. Notwithstanding the foregoing provisions of this ARTICLE 9, if (a) there is Confidential Information of a Party hereunder that is also Confidential Information of such Party under the Master Agreement, a Co-Co Collaboration Agreement or another License Agreement (as “Confidential Information” is defined in such other agreement), and (b) there is a conflict between the provisions of this Agreement, on the one hand, and the Master Agreement, a Co-Co Collaboration Agreement or License Agreement, as applicable, on the other hand, with respect to the disclosure and non-use of such Confidential Information, the provisions of the agreement that provides the most protection of a Party’s Confidential Information (i.e., Licensee, with respect to Licensee’s Confidential Information, and Licensor, with respect to Licensor’s Confidential Information) shall control.

13.5.2Either Party may require that any dispute, other than Expedited Matters (which are governed by Schedule 1 and are referred to Executive Officers pursuant to the terms thereof) and Expert Disputes (which are governed by Schedule 2), be submitted to the Executive Officers for resolution by providing written notice to the other Party formally requesting that the dispute be resolved by the Executive Officers and specifying the nature of the dispute with sufficient specificity to permit adequate consideration by such Executive Officers. If a dispute is

referred to the Executive Officers, then the Executive Officers shall diligently and in good faith attempt to resolve the referred dispute within thirty (30) days after receiving written notification of such dispute or such longer period of time as the Executive Officers may agree in writing. Any final decision mutually agreed to by the Executive Officers with respect to a dispute and set forth in writing shall be conclusive and binding on the Parties. If the Executive Officers cannot resolve such dispute within such thirty (30) days or such other period as agreed by the Executive Officers, such dispute will be resolved as follows:

(b)with respect to any Expedited Matter, such Expedited Matter shall be resolved pursuant to the provisions of Schedule 1;

(c)if the dispute is related to (A) whether a given activity is an Alnylam Specific Activity or (B) whether a targeting ligand or other delivery technology proposed under Section 3.6 is a type of Non-Relevant Organ Delivery Technology (each of clauses (A) and (B), an “Expert Dispute”), the Parties will mutually agree on an Expert and will submit such matter for resolution by such Expert in accordance with Schedule 2, and the determination of the Expert will be binding on the Parties. For avoidance of doubt, the Parties shall be bound by the determination of such Expert; and

(d)with respect to all other disputes, including Legal Disputes, the Parties shall be free to pursue any rights and remedies available to them at law, in equity or otherwise subject, however, to Section 13.4.1 and Section 13.9.

13.7.1This Agreement[, the Supply Agreement (if any) and the Quality Agreement (if any),]¹⁵⁰ and the Master Agreement, together with the schedules attached hereto and thereto, sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and all prior agreements, understandings, promises, and representations, whether written or oral, with respect thereto are superseded hereby. Each Party confirms that it is not relying on any representations or warranties of the other Party except as specifically set forth in this Agreement[, the Supply Agreement (if any) and the Quality Agreement (if any),]¹⁵¹ or the Master Agreement. In the event of a conflict between the provisions of this Agreement and the Master Agreement with respect to the Target Program (or the Target or Collaboration Products thereunder), the provisions of this Agreement shall control. For the avoidance of doubt, the Parties agree and acknowledge that from and after the Effective Date, there shall be no additional Development, Manufacturing or Commercialization activities with respect to the Target Program or the Exploitation of Collaboration Products pursuant to the Master Agreement.

13.7.2No amendment, modification, release, or discharge shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties.

13.8LIMITATION OF DAMAGES. IN NO EVENT SHALL LICENSEE OR LICENSOR BE LIABLE FOR SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING, LOSS OF PROFITS) SUFFERED BY THE OTHER PARTY, REGARDLESS OF THE THEORY OF LIABILITY (INCLUDING CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE) AND REGARDLESS OF ANY PRIOR NOTICE OF SUCH DAMAGES. HOWEVER, NOTHING IN

THIS SECTION 13.8 IS INTENDED TO LIMIT OR RESTRICT (A) LIABILITY FOR BREACH OF SECTION 6.7.1 OR ARTICLE 9 OR (B) THE INDEMNIFICATION RIGHTS AND OBLIGATIONS OF EITHER PARTY HEREUNDER AS SET FORTH IN SECTION 11.1 WITH RESPECT TO CLAIMS.

13.9Equitable Relief. Each Party acknowledges and agrees that the restrictions set forth in Section 6.7 and ARTICLE 9 are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any provision of such Section or Article may result in irreparable injury to such other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of such Section or Articles, the non-breaching Party shall be authorized and entitled to seek from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance, and an equitable accounting of all earnings, profits, and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity. Each Party hereby waives any requirement that the other Party, as a condition for obtaining any such relief (a) post a bond or other security or (b) show irreparable harm, balancing of harms, consideration of the public interest, or inadequacy of monetary damages as a remedy. Nothing in this Section 13.9 is intended, or should be construed, to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement.

13.13Relationship of the Parties. It is expressly agreed that Licensor, on the one hand, and Licensee, on the other hand, shall be independent contractors and that the relationship between the two (2) Parties shall not constitute a partnership, joint venture, or agency. Neither Licensor, on the one hand, nor Licensee, on the other hand, shall have the authority to make any statements, representations, or commitments of any kind, or to take any action, which shall be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of such Party and not of the other Party and all costs and obligations incurred by reason of any such employment shall be for the account and expense of such Party.

13.16Schedules. In the event of any inconsistencies between this Agreement and any schedules or other attachments hereto, the terms of this Agreement shall control.

THIS AGREEMENT IS EXECUTED by the authorized representatives of the Parties as of the Effective Date.
