The Master Collaboration Agreement is not intended to provide any factual information about Alnylam. The Master Collaboration Agreement contains representations, warranties and covenants that Alnylam and Genzyme made to each other as of specific dates. The assertions embodied in those representations, warranties and covenants were made solely for purposes of the Master Collaboration Agreement between Alnylam and Genzyme and may be subject to important qualifications and limitations agreed to by Alnylam and Genzyme in connection with negotiating its terms, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Master Collaboration Agreement. Moreover, the representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to investors or security holders, or may have been used for the purpose of allocating risk between Alnylam and Genzyme rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Master Collaboration Agreement, which subsequent information concerning the subject matter of the representations and warranties may change after the date of the Master Collaboration Agreement, which subsequent information may or may not be fully reflected in Alnylam’s public disclosures. For the foregoing reasons, no person should rely on the representations and warranties as statements of factual information at the time they were made or otherwise.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants herein contained, the Parties hereby agree as follows:

1.1. Overview of Transactions. This Master Agreement is part of the Collaboration Agreement between Genzyme and Alnylam under which the Parties are Developing and Commercializing ALN-TTR02 and ALN-TTRsc and under which Alnylam has granted Genzyme various Options to obtain licenses to Develop and Commercialize siRNAs generated by Alnylam’s Core Pipeline Programs, subject to the terms and conditions of this Master Agreement. As of the Effective Date, the Collaboration Agreement shall supersede and replace the Historical TTR Agreement pursuant to which Alnylam granted Genzyme certain exclusive licenses and other rights with respect to ALN-TTR02 and ALN-TTRsc in certain Asian countries. The Collaboration Agreement consists of: (a) this Master Agreement; (b) the Regional License Terms, which are attached to this Master Agreement as Appendix A; (c) the Co-Co License Terms, which are attached to this Master Agreement as Appendix B; (d) the Global License Terms, which are attached to this Master Agreement as Appendix C; and (e) the schedules and exhibits attached to each of the foregoing. As of the Effective Date, ALN-TTR02 shall be a Regional Licensed Product and, as such, shall be governed by this Master Agreement and the Regional License Terms. As of the Effective Date, ALN-TTRsc shall be a Co-Co Licensed Product and, as such, shall be governed by this Master Agreement and the Co-Co License Terms.

This Master Agreement includes, among other things, the terms of the various Options granted to Genzyme (i.e., the Regional Option, the 2019 Trailing Regional Option, the 2021 Trailing Regional Option, the Co-Co/Global Option, the Global Option, the Additional Global Option and the Trailing Global Option), and the process for exercising such Options. The Master Agreement sets forth, among other things, the Parties’ obligations to one another with respect to the Core Pipeline Programs during the period when Genzyme may exercise such Options.

This Master Agreement also contains certain terms and conditions that are applicable to all of the “Collaboration Products” (i.e., siRNAs with respect to which Genzyme exercises one of its Options) after Genzyme exercises an Option with respect to any such Collaboration Product. For example, the Master Agreement describes portions of the overall governance structure for the Collaboration and also includes manufacture and supply terms, payment terms, confidentiality and publication provisions, indemnification, limitations of liability, insurance requirements, provisions regarding intellectual property and in-licenses, and miscellaneous provisions that are applicable to the Collaboration Products, subject to the terms and conditions of this Master Agreement and the applicable License Terms.

Following Genzyme’s exercise of an Option for an siRNA generated by an Alnylam Core Pipeline Program (or, with respect to ALN-TTR02 and ALN-TTRsc, following the Effective Date of the Collaboration Agreement), the Development and Commercialization of the applicable siRNA will be governed by this Master Agreement and one of the 3 Appendices attached to the Master Agreement as follows:

(1) The Regional License Terms will govern the Parties’ joint Development and Commercialization of ALN-TTR02 and any siRNA for which Genzyme exercises a Regional Option, including the 2019 Trailing Regional Option or a 2021 Trailing Regional Option. Any such siRNA is referred to as a “Regional Licensed Product.” Under the Regional License Terms, Genzyme shall acquire a license to Develop and Commercialize Regional Licensed Products in only the Genzyme Territory.

(2) The Co-Co License Terms will govern the Parties’ joint Development and Commercialization of ALN-TTRsc, and will also govern the Parties’ joint Development and Commercialization of ALN-AT3 if Genzyme exercises the Co-Co/Global Option to acquire a license to Develop and Commercialize ALN-AT3 in the Genzyme Territory and to co-Commercialize ALN-AT3 in the Alnylam Territory. Each such siRNA is referred to as a “Co-Co Licensed Product.” Subject to the specific terms in this Master Agreement and to the Co-Co License Terms, the Co-Co License Terms are largely identical to the Regional License Terms with respect to the Genzyme Territory, but provide for additional terms governing the co-Commercialization of Co-Co Licensed Products in the Alnylam Territory.

(3) The Global License Terms will govern Genzyme’s Development and Commercialization of ALN-AS1 if Genzyme exercises the Co-Co/Global Option for ALN-AS1, and any siRNA for which Genzyme exercises the Global Option, the Additional Global Option or the Trailing Global Option. Each such siRNA is referred to as a “Global Licensed Product.” Under the Global License Terms, Genzyme shall acquire the exclusive right to Develop and Commercialize Global Licensed Products worldwide.

Unlike the Master Agreement, which contains terms that apply to all Collaboration Products, the License Terms include only terms that apply to the specific type of Collaboration Product to which the License Terms relate, such as economic terms, license grants, product-specific governance provisions, Development and Commercialization provisions, intellectual property provisions, and provisions relating to term and termination, including termination on a product-by-product basis, in each case subject to the specific terms of the License Terms.

None of the following agreements in existence or being negotiated on the Execution Date shall constitute a “Third Party CNS Agreement” for purposes of this Master Agreement: (i) the agreements between Genzyme and a Third Party that will be identified by Genzyme by the Effective Date and added to Schedule 2.1.3.3 and (ii) the agreements between Alnylam and a Third Party, listed on Schedule 2.1.3.3, in each case ((i) and (ii)) as such agreements may be amended or restated in the future so long as such amendment or restatement does not expand the field of such agreement, and the activities thereunder and discussions with such Third Party in relation thereto.

(b) Future Third Party Agreements. The following shall not constitute “Third Party CNS Agreements” for purposes of this Master Agreement: (i) any agreement between a Party and a contractor, contract research organization, contract manufacturer or other Third Party, under which such Third Party only performs contract services on behalf of such Party, for the research, development or manufacture of siRNAs delivered to the CNS and for which no product-related commercial rights are granted or (ii) any agreement between a Party and an academic institution or non-profit institution, under which such Party and such institution collaborate with respect to the research, development or manufacture of siRNAs delivered to the CNS and for which no product-related commercial rights are granted.

(c) Internal Activities. Notwithstanding anything in this Section 2.1.3 (CNS Collaboration), either Party may conduct internal programs and other activities regarding the research, development, manufacture and commercialization of siRNAs to be delivered to the CNS.

(a) ROFN Process. If Genzyme makes a request to negotiate under Section 2.1.3.1, but the Parties do not enter into, a CNS Collaboration and License Agreement during the CNS Exploration Period and Genzyme does not terminate the CNS Exploration Period prior to its expiration, then, if at any time during the [***] year period following the CNS Exploration Period (the “CNS ROFN

Period”), Alnylam desires to enter into a Third Party CNS Agreement, Alnylam shall so notify Genzyme in writing, which notice shall describe the proposed terms of such Third Party CNS Agreement (the “Proposed CNS Terms”). Upon receipt of such notice from Alnylam, Genzyme shall have [***] days from receipt of such written notice to notify Alnylam in writing as to whether Genzyme desires to negotiate an agreement with Alnylam with respect to the Proposed CNS Terms (a “CNS ROFN Exercise Notice”). If Genzyme delivers a CNS ROFN Exercise Notice prior to the expiration of such [***] day period, Genzyme shall have the exclusive right [***] days following the date that Genzyme delivers a CNS ROFN Exercise Notice (the “CNS ROFN Offer Period”) to negotiate with Alnylam and to make one or more written non-binding offers to Alnylam concerning the terms on which Genzyme would enter into an agreement with respect to the Proposed CNS Terms (the “CNS ROFN Non-Binding Offer”). If Genzyme delivers a CNS ROFN Non-Binding Offer to Alnylam prior to the expiration of the CNS ROFN Offer Period, Genzyme shall thereafter have the exclusive right for [***] days (or such longer period as may be mutually agreed by the Parties) (the “CNS ROFN Negotiation Period”), to finalize and enter into a definitive agreement with Alnylam with respect to the Proposed CNS Terms.

(b) Post-ROFN MFN. Alnylam shall not, during the CNS ROFN Offer Period or CNS ROFN Negotiation Period, enter into discussions, exchange information, or otherwise negotiate with any Third Party with respect to the Proposed CNS Terms. If (i) Genzyme does not provide a CNS ROFN Exercise Notice within [***] days of receiving notice of the Proposed CNS Terms, (ii) Genzyme does not provide a CNS ROFN Non-Binding Offer prior to the expiration of the CNS ROFN Offer Period prior to the expiration of the CNS ROFN Offer Period, or (iii) the Parties do not enter into a definitive agreement with respect to the Proposed CNS Terms prior to the expiration of the CNS ROFN Negotiation Period, then Alnylam shall be free to enter into an agreement with any Third Party with respect to such Proposed CNS Terms, provided that, for the remainder of the CNS ROFN Period, Alnylam shall not enter into an agreement with respect to such Proposed CNS Terms that are, in the aggregate, materially more favorable to such Third Party than the last terms offered in writing by Genzyme to Alnylam during the CNS ROFN Offer Period or CNS ROFN Negotiation Period, as applicable, unless Alnylam first re-offers to enter into an agreement with Genzyme on such more favorable terms and Genzyme does not accept such offer and enter into such agreement with Alnylam within [***] days after such re-offer. For clarity, prior to the CNS ROFN Offer Period and CNS ROFN Exercise Period, Alnylam shall be free to engage in discussions and exchange information with Third Parties with respect to development or commercialization of siRNAs delivered to the CNS, but shall not enter into any binding agreement with any Third Party with respect to such rights.

(c) Notwithstanding the foregoing, in the event that Genzyme enters into any Third Party CNS Agreement following the Execution Date without the prior written consent of Alnylam, Genzyme’s exclusive rights under this Section 2.1.3 shall automatically convert to non-exclusive rights and the proviso set forth in Section 2.1.3.4(b) (Post-ROFN MFN) shall automatically no longer apply. The foregoing shall be Alnylam’s sole and exclusive remedy with respect to any breach of Section 2.1.3.2 (CNS Exclusivity) by Genzyme.

2.2. Effectiveness of Licenses to Collaboration Products. As promptly as practicable following Alnylam’s delivery of a Final Option Data Package to Genzyme, but not later than the applicable Option Exercise Date, Genzyme shall determine whether any filing or notification is necessary or advisable under any applicable Antitrust Law if Genzyme were to exercise the respective Option to take a license from Alnylam to Genzyme in respect of the corresponding Option Product pursuant to the applicable License Terms.

2.2.1. If Genzyme determines that a filing or notification under any applicable Antitrust Law is not necessary or advisable, then Genzyme shall indicate the same in the respective Exercise Notice for such Option.

2.2.2. If Genzyme determines that a filing or notification under any applicable Antitrust Law is necessary or advisable, then Genzyme shall indicate the same in the respective Exercise Notice for such Option and each of Genzyme and Alnylam shall make or cause to be made such notifications and filings as promptly as practicable (but in any event within [***] business days). Each Party shall be responsible for its own costs and expenses associated with such notifications and filings, and Genzyme shall pay any applicable premerger filing fee under the HSR Act. Each Party shall use its commercially reasonable efforts to obtain the expiration or termination of the applicable waiting period under the HSR Act, and to obtain the termination or expiration of any other applicable waiting periods or any necessary approvals or consents under any other applicable Antitrust Law, at the earliest possible date after the date of filing. Immediately following the later of the expiration or termination of the last such waiting period, or receipt of any necessary approvals or consents under any other applicable Antitrust Law, Genzyme shall send Alnylam written notice that all waiting periods under any applicable Antitrust Law have expired or been terminated and any necessary approvals or consents under any applicable Antitrust Law have been obtained. The effectiveness of the Option Exercise Date for the corresponding Collaboration Product, which will be the Implementation Date under the applicable License Terms, shall be deemed to be delayed until the date on which the last waiting period under any applicable Antitrust Law has expired or been terminated or on which the last approval or consent under such Antitrust Law is granted.

2.3. Cooperation. Each of Genzyme and Alnylam shall: (i) reasonably cooperate with each other in connection with any investigation or other inquiry relating to the transactions contemplated by an Exercise Notice for an Option; (ii) reasonably keep the other Party informed of any communication received by such Party from, or given by such Party to, the FTC, the DOJ or any other Merger Control Authority and of any communication received or given in connection with any proceeding by a private party, in each case regarding the transactions contemplated by an Exercise Notice for an Option; (iii) promptly respond to and certify substantial compliance with any inquiries or requests received from the FTC, the DOJ or any other Merger Control Authorities for additional information or documentation; (iv) reasonably consult with each other in advance of any meeting or conference with the FTC, the DOJ or any other Merger Control Authority, and to the extent permitted by the FTC, the DOJ or such other Merger Control Authority and reasonably determined by such Party to be appropriate under the circumstances, give the other Parties or their counsel the opportunity to attend and participate in such meetings and conferences; and (v) permit the other Parties or their counsel to the extent reasonably practicable to review in advance, and in good faith consider the views of the other Parties or their counsel concerning, any submission, filing or communication (and documents submitted therewith) intended to be given by it to the FTC, the DOJ or any other Merger Control Authority; provided, however, such Party shall be under no obligation to reschedule any meetings or conferences with the FTC, the DOJ or any other Merger Control Authority to enable the other Party to attend.

2.4. No Antitrust Undertakings. Notwithstanding anything to the contrary in this Section 2, the term “commercially reasonable efforts” as used in this Section 2 does not require that either Party (i) offer, negotiate, commit to or effect, by consent decree, hold separate order, trust or otherwise, the sale, divestiture, license or other disposition of any capital stock, assets, rights, products or businesses of Genzyme, Alnylam or their respective Affiliates, (ii) agree to any restrictions on the activities of Genzyme, Alnylam or their respective Affiliates, or (iii) pay any material amount or take any other action to prevent, effect the dissolution of, vacate, or lift any decree, order, judgment, injunction, temporary restraining order, or other order in any suit or proceeding that would otherwise have the effect of preventing or delaying any of the transactions contemplated by an Exercise Notice for an Option.

2.5.1. Transaction Agreements. The Collaboration Agreement shall (i) not take effect until the occurrence of the Closing (as defined in the Stock Purchase Agreement) in accordance with its terms and (ii) become null and void and have no further force or effect in the event the Stock Purchase Agreement is terminated prior to the Closing in accordance with its terms.

2.5.2. License to an Option Product. At the election of either Party, immediately upon notice to the other Party, Genzyme’s exercise of an Option shall become null and void and have no further force or effect (i) in the event that the FTC or DOJ obtains a preliminary injunction against the Parties to enjoin the transactions contemplated by the Exercise Notice for such Option or (ii) in the event any applicable

waiting periods shall not have expired or been terminated, or any necessary approvals or consents shall not have been obtained, under any applicable Antitrust Law on or prior to [***] months after the effectiveness of the filings and notifications contemplated by Section 2.2.2 (Effectiveness of Licenses to Collaboration Products). In addition, beginning on the [***] day following Genzyme’s delivery of an Exercise Notice with respect to an Option Product but prior to the Option Exercise Date for the corresponding Collaboration Product, Genzyme shall have the right to nullify its exercise of such Option by providing written notice to Alnylam. Following the voiding or nullification of Genzyme’s exercise of an Option for any reason under this Section 2.5, the Option Product previously subject to such Option shall be treated for all purposes under this Master Agreement, including Section 3.5, as an Option Product in respect of which Genzyme did not deliver an Exercise Notice to Alnylam.

3.1.1.1. Alnylam Development Updates. At each regularly scheduled meeting of the PAC during the Option Period, Alnylam shall advise the PAC of any Alnylam Program with respect to which, since the last PAC meeting, either (i) the existence of such Alnylam Program (and the target thereof) has been publicly disclosed by Alnylam, including as a result of the filing of an IND for such siRNA or (ii) [***]. In addition, Alnylam may elect to advise the PAC of any Alnylam Program at any time. The PAC shall discuss the selection of new targets for new Core Pipeline Programs and the research and development strategy for Option Products. Alnylam shall consider in good faith recommended new targets proposed by Genzyme.

3.1.1.2. PAC Categorization of Alnylam Programs. The PAC, acting reasonably, shall seek to determine whether such Alnylam Program is a Core Pipeline Program or a Non-Core Pipeline Program and advise the Parties of its consensus view (if any).

(a) If the PAC recommends to the AJSC and to the Parties that any Alnylam Program is a Core Pipeline Program or a Non-Core Pipeline Program, then the Parties may agree that such Alnylam Program shall be identified on the Core Pipeline Program List or the Non-Core Program Pipeline List, respectively. Any Alnylam Program and the corresponding human gene and siRNA, for as long as listed on the Core Pipeline Program List or Non-Core Pipeline Program List, shall be treated as a Core Pipeline Program or Non-Core Pipeline Program, as applicable, for all purposes of this Master Agreement, subject to this Section 3.1.1.

(b) If, within [***] days of the PAC meeting referred to in Section 3.1.1.2 (PAC Categorization of Alnylam Programs), the Parties, acting reasonably, are unable to agree on whether any such Alnylam Program is a Core Pipeline Program or a Non-Core Pipeline Program, then such Alnylam Program shall be deemed to be a “Tentative Core Pipeline Program” and shall be identified on a list of such Tentative Core Pipeline Programs (the “Tentative Core Pipeline Program List”) and, for the sake of clarity, except as provided in Section 3.1.1.5 (Requested Dispute Resolution), such disagreement shall not be subject to resolution pursuant to Section 5.1.8 (Decision-Making). Any Alnylam Program and the corresponding human gene and siRNA, for as long as listed on the Tentative Core Pipeline Program List, shall be treated as a Core Pipeline Program for purposes of Section 3.1.2.1 (Information Sharing for Core Pipeline Programs), Section 3.1.2.2 (Meetings with Regulatory Authorities), Section 3.1.2.3 (Design of Human POP Studies), Section 3.6 (Exclusivity during Option Period), Section 5.3.3 (IP Committee Responsibilities) and Section 11 (Intellectual Property), subject to Section 3.1.1 (Program Identification).

3.1.1.4. Locking of Alnylam Programs. Alnylam shall notify the PAC promptly after the first IND with respect to an Alnylam Program becomes, or is deemed to be, effective and (i) if such Alnylam Program is on the Core Pipeline Program List or Non-Core Pipeline Program List, it will automatically be moved to the Locked Core Pipeline Program List or the Locked Non-Core Pipeline Program List, as applicable, upon delivery of such notice; or (ii) if such Alnylam Program is on the Tentative Core Pipeline Program List, then the Parties will seek to reach consensus as to whether such Alnylam Program is a Core Pipeline Program or Non-Core Pipeline Program within [***] days after delivery of such notice. If the Parties agree on the categorization of such Tentative Core Pipeline Program within such [***] day period, such Alnylam Program will automatically be moved to the Locked Core Pipeline Program List or the Locked Non-Core Pipeline Program List, as applicable. If the Parties cannot agree within such [***] day period, either Party may submit the categorization of such Alnylam Program to the AJSC for resolution pursuant to Section 5.1.8 (Decision-Making) and, following any such resolution of such categorization, such Alnylam Program will automatically be moved to the Locked Core Pipeline Program List or the Locked Non-Core Pipeline Program List, as applicable. Once an Alnylam Program has been moved to the Locked Core Pipeline Program List or the Locked Non-Core Pipeline Program List, such Core Pipeline Programs shall remain Core Pipeline Programs and such Non-Core Pipeline Programs shall remain Non-Core

Pipeline Programs, respectively, for all purposes under the Collaboration Agreement, except as the Parties, each acting in its sole discretion, may later mutually agree in writing. Notwithstanding the foregoing, if Alnylam enters into an agreement with a Third Party granting such Third Party any rights or options to a Non-Core Pipeline Program (or any siRNA arising therefrom) prior to the first IND with respect to such Non-Core Pipeline Program becoming effective, Alnylam shall notify the PAC of the existence of such an agreement (but not the counterparty thereto or any terms thereof) and the human gene(s) targeted by such Non-Core Pipeline Program (or any siRNA arising therefrom) and such Non-Core Pipeline Program will automatically then be moved to the “Locked Non-Core Pipeline Program List” as of the date of such agreement, [***].

3.1.1.5. Requested Dispute Resolution. If an Alnylam Program is not listed on the Locked Core Pipeline Program List or the Locked Non-Core Pipeline Program List and the Parties, at any time, are unable to agree on whether any such Alnylam Program is a Core Pipeline Program or a Non-Core Pipeline Program then, upon the request of either Party, such categorization of such Alnylam Program shall be submitted to the AJSC for resolution pursuant to Section 5.1.8 (Decision-Making), and, following resolution, such Alnylam Program will automatically be moved to the Locked Core Pipeline Program List or the Locked Non-Core Pipeline Program List, as applicable.

3.1.1.6. Updating Program Lists. Solely as an administrative manner, Alnylam shall be responsible for updating the Core Pipeline Program List, the Locked Core Pipeline Program List, the Non-Core Pipeline Program List, the Locked Non-Core Pipeline Program List and the Tentative Core Pipeline Program List from time to time, in all cases in accordance with this Section 3.1.1. Promptly following any such update, Alnylam shall provide a copy of the applicable list to each of the PAC representatives.

(a) During the Option Period, Alnylam shall update the PAC, at each regularly scheduled meeting thereof, on the status of the Core Pipeline Programs, which update shall include a summary of the Development activities undertaken by Alnylam with respect to such Core Pipeline Programs since the last update provided to the PAC or planned to be undertaken by Alnylam. [***]. In addition, in connection with each regularly scheduled meeting of the PAC during the Option Period, Alnylam will provide to the PAC and Genzyme copies of all then-available preclinical, clinical, regulatory and supporting reports and material correspondence with Regulatory Authority with respect to any Core Pipeline

Program and, if available, a copy of any Development plan for each Core Pipeline Program. Notwithstanding the foregoing, Alnylam shall not be obligated pursuant to the foregoing to provide information the disclosure of which would: (a) in the reasonable opinion of Alnylam’s counsel, adversely affect the attorney-client privilege between Alnylam and its counsel; or (b) violate or cause a breach by Alnylam of any confidentiality or non-disclosure agreement with any Third Party. Once Alnylam delivers an Initial Option Data Package for an Option Product, Alnylam will provide information related to such Option Product solely pursuant to Section 3.3 (Option Exercise Period), including Section 3.3.3.2 (Governance) if Genzyme delivers an Option Preservation Notice for such Option Product to Alnylam, and Alnylam shall not have any obligations related to such Option Product and its related Core Pipeline Program under Sections 3.1.1 (Program Identification), 4.5 (Oversight), 5 (Collaboration Management) or 11.2 (Patent Prosecution Information Sharing).

(b) Following the filing of an IND with respect to a Core Pipeline Program, Alnylam shall (x) promptly provide (i) any patent, regulatory or CMC information, (ii) any material, complete sets of preclinical or clinical data and (iii) raw data tables, in each case ((i), (ii) and (iii)) then available to Alnylam that Genzyme may reasonably request, to the extent that such information was not previously provided by Alnylam to Genzyme and subject to customary and reasonable due diligence procedures to preserve the confidential nature of any such information, regarding such Option Product to assist Genzyme in deciding whether to exercise an Option for such Option Product if and when any such Option becomes exercisable; and (y) afford to Genzyme and its representatives, reasonable access during normal business hours to Alnylam’s personnel that Genzyme may reasonably request regarding such Option Product to assist Genzyme in deciding whether to exercise an exercisable Option for such Option Product.

3.1.2.2. Meetings with Regulatory Authorities. Alnylam shall provide Genzyme with reasonable advance notice of any pre-IND meetings with any Regulatory Authority with respect to any Core Pipeline Program, or with as much advance notice as practicable under the circumstances. [***].

3.1.2.3. Design of Human POP Studies. During the Option Period, Alnylam shall reasonably consult with the AJSC regarding the design of each Human POP Study proposed to be conducted for any siRNA generated by a Core Pipeline Program. In addition, at least [***] days prior to submitting a final protocol for such Human POP Study to a Regulatory Authority as part of an IND, Alnylam shall submit a draft of such protocol (or, if a draft protocol is not available, a full protocol concept sheet) to the AJSC for review and comment. If a draft protocol was not available, Alnylam shall provide the draft protocol to the

AJSC as soon as it becomes available. Alnylam shall reasonably consider in good faith any comments provided by the AJSC (or its members) within [***] days of the submission of such draft protocol or full protocol concept sheet to the AJSC; provided, however, in any event, the AJSC shall have at least [***] days to review and comment on the draft protocol. [***].

3.1.2.4. Improperly Designated Programs. In the event that (i) it is determined [***] and (iii) Alnylam continues to conduct such Alnylam Program following such [***] determination as a Non-Core Pipeline Program, but does not initiate a Phase II Study for any siRNA generated by such Non-Core Pipeline Program in a non-Orphan Disease or any cancer or infectious disease within [***] following the date on which such siRNA received Regulatory Approval in respect of an Orphan Disease, then Alnylam and Genzyme shall in good faith negotiate together the terms under which such siRNA could be deemed a Regional Option Product (even if such [***] year period ends after the expiration of the Regional Option Period), including [***]. Following agreement on such terms, Alnylam shall provide Genzyme with an Initial Option Notice with respect to the applicable siRNAs as soon as reasonably practicable. If the Parties are unable to agree upon the terms under which such siRNA could be deemed a Regional Option Product during the first [***] days of such negotiation, [***].

3.2.1.1. Regional Option Grants. Alnylam hereby grants Genzyme a series of exclusive options (each, a “Regional Option”), under each of which Genzyme shall have the right, but not the obligation, to take a license on the terms set forth in the Regional License Terms to any Regional Option Product that achieves Human POP Study Completion during the Regional Option Period. Each Regional Option may be exercised by Genzyme at any time during the applicable Option Exercise Period for a Regional Option Product that achieves Human POP Study Completion in accordance with the terms and conditions set forth in Sections 3.3 (Option Exercise Period) and 3.4 (Exercise of an Option).

3.2.2. Co-Co/Global Option Grant. Alnylam hereby grants Genzyme one (1) exclusive option (the “Co-Co/Global Option”) under which Genzyme shall have the right, but not the obligation, to either (i) take a license on the terms set forth in the Global License Terms to ALN-AS1 or (ii) take a license on the terms set forth in the Co-Co

License Terms to ALN-AT3. Genzyme may wait to exercise such Co-Co/Global Option until both ALN-AS1 and ALN-AT3 achieve Human POP Study Completion as described below in this Section 3.2.2, or may terminate such Co-Co/Global Option prior to both ALN-AS1 and ALN-AT3 achieving Human POP Study Completion (in which case, the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant)). The Co-Co/Global Option may be exercised by Genzyme at any time during the applicable Option Exercise Period for a Co-Co/Global Option Product in accordance with the terms and conditions set forth in Sections 3.3 (Option Exercise Period) and 3.4 (Exercise of an Option), subject to the conditions set forth in this Section 3.2.2.

3.2.2.1. First Co-Co/Global Option Product. For the first Co-Co/Global Option Product to achieve Human POP Study Completion (the “First Co-Co/Global Option Product”), Genzyme may do any of the following:

(a) exercise a Regional Option (or 2019 Trailing Regional Option or 2021 Trailing Regional Option, if and as applicable) for such First Co-Co/Global Option Product, in which case the Co-Co/Global Option shall remain exercisable with respect to the First Co-Co/Global Option Product on the terms set forth in Sections 3.2.2.2(a) (Second Co-Co/Global Option Product) and 3.2.2.4 (Discontinuation of Second Co-Co/Global Option Product);

(b) exercise the Co-Co/Global Option for the First Co-Co/Global Option Product, in which case the Co-Co/Global Option shall be fully exercised; or

(c) not exercise any Option for the First Co-Co/Global Option Product, in which case the Co-Co/Global Option shall cease to be exercisable with respect to the First Co-Co/Global Option Product but shall remain exercisable for the Second Co-Co/Global Option Product.

3.2.2.2. Second Co-Co/Global Option Product. For the second Co-Co/Global Option Product (i.e., if the First Co-Co/Global Option Product is ALN-AT3, then ALN-AS1 or, if the First Co-Co/Global Option Product is ALN-AS1, then ALN-AT3) to achieve Human POP Study Completion (the “Second Co-Co/Global Option Product”), Genzyme may do any of the following:

(a) exercise the Co-Co/Global Option for the First Co-Co/Global Option Product, in which case the Co-Co/Global Option shall be fully exercised;

(b) exercise the Co-Co/Global Option for the Second Co-Co/Global Option Product, in which case the Co-Co/Global Option shall be fully exercised;

(c) exercise a Regional Option (or 2019 Trailing Regional Option or 2021 Trailing Regional Option, if and as applicable) for the Second Co-Co/Global Option Product, in which case, the Co-Co/Global Option shall be terminated in full and the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant) (for clarity, Genzyme may do both (a) and (c) of this Section 3.2.2.2); or

(d) not exercise any Option for the Second Co-Co/Global Option Product, in which case

(i) if the Second Co-Co/Global Option Product achieved Clinical Success (and Genzyme does not exercise the Co-Co/Global Option for the First Co-Co/Global Option Product or the Second Co-Co/Global Option Product or Genzyme has terminated the Co-Co/Global Option pursuant to Section 3.2.2.5 (Genzyme Elective Termination of Co-Co/Global Option)), the Co-Co/Global Option shall terminate in full at the end of the Option Exercise Period for the Second Co-Co/Global Option Product and the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant);

(ii) if the Second Co-Co/Global Option Product did not achieve Clinical Success, but the First Co-Co/Global Option Product did achieve Clinical Success (and Genzyme does not exercise the Co-Co/Global Option for the First Co-Co/Global Option Product or the Second Co-Co/Global Option Product or Genzyme has terminated the Co-Co/Global Option pursuant to Section 3.2.2.5 (Genzyme Elective Termination of Co-Co/Global Option)), then the Co-Co/Global Option shall terminate in full at the end of the Option Exercise Period for the Second Co-Co/Global Option Product and the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant);

(iii) if both the Second Co-Co/Global Option Product and the First Co-Co/Global Option Product failed to achieve Clinical Success, then the Co-Co/Global Option shall remain exercisable but only with respect to the next Co-Co/Global Option Product, if any, to achieve Clinical Success (the “Back-Up Co-Co/Global Option Product”).

3.2.2.3. Back-Up Co-Co/Global Option Product. If the Co-Co/Global Option is exercisable with respect to the Back-Up Co-Co/Global Option Product pursuant to Section 3.2.2.2(d)(iii), Genzyme may do any of the following:

(a) exercise the Co-Co/Global Option for the Back-Up Co-Co/Global Option Product, in which case the Co-Co/Global Option shall be fully exercised; or

(b) not exercise the Co-Co/Global Option for the Back-Up Co-Co/Global Option Product, in which case the Co-Co/Global Option shall terminate in full at the end of the Option Exercise Period for the Back-Up Co-Co/Global Option Product and the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant).

3.2.2.4. Discontinuation of Second Co-Co/Global Option Product. If Genzyme exercises a Regional Option for the First Co-Co/Global Option Product and Alnylam decides to abandon or terminate Development of the other Co-Co/Global Option Product prior to achieving Human POP Study Completion, then Alnylam shall promptly deliver written notice of such abandonment or termination to Genzyme (any such notice, the “Co-Co/Global Option Trigger Notice”) and Genzyme may do either of the following:

(a) exercise the Co-Co/Global Option for the First Co-Co/Global Option Product, in which case the Co-Co/Global Option shall be fully exercised and the First Co-Co/Global Option Product shall cease to be a Regional Licensed Product; or

(b) not exercise the Co-Co/Global Option for the First Co-Co/Global Option Product, in which case the Co-Co/Global Option shall terminate in full at the end of the applicable Option Exercise Period, the First Co-Co/Global Option Product shall continue to be a Regional Licensed Product and the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant).

3.2.2.5. Genzyme Elective Termination of Co-Co/Global Option. At any time prior to the exercise of the Co-Co/Global Option, Genzyme may, in its sole discretion, terminate the Co-Co/Global Option by providing written notice of termination to Alnylam and, upon delivery of such notice, the Co-Co/Global Option shall irrevocably and perpetually terminate in full, the Option Exercise Period for the Co-Co/Global Option shall expire, and the Additional Global Option will become exercisable pursuant to Section 3.2.3.2 (Additional Global Option Grant).

3.2.3.1. Global Option Grant. Alnylam hereby grants Genzyme one (1) exclusive option (the “Global Option”), under which Genzyme shall have the right, but not the obligation, to take a license on the terms set forth in the Global License Terms to any Global Option Product for which it is anticipated that Human POP Study Completion will be achieved during the Global Option Period. The Global Option may be exercised by Genzyme at any time during the applicable Option Exercise Period for a Global Option Product for which a Human POP Study is conducted during the Global Option Period in accordance with the terms and conditions set forth in Sections 3.3 (Option Exercise Period) and 3.4 (Exercise of an Option). The Global Option shall terminate in full upon the Option Exercise Date for any Global Option Product with respect to which Genzyme exercises the Global Option.

3.3.1. Initial Option Data Package. As soon as is reasonably practicable on or after [***] (i) any Option Product that achieves Human POP Study Completion during the applicable Option Period or (ii) any Trailing Regional Option Product or Trailing Global Option Product that achieves Human POP Study Completion after the end of the applicable Option Period; (y) Genzyme notifies Alnylam that it desires to exercise the Co-Co/Global Option with respect to ALN-AS1 prior to the achievement of Human POP Study Completion; or (z) Genzyme notifies Alnylam that it desires to exercise the Global Option or the Additional Global Option with respect to a Global Option Product prior to the achievement of Human POP Study Completion, Alnylam shall complete all activities necessary for Alnylam to prepare a complete Initial Option Data Package for the applicable Option Product and provide a written notice to Genzyme (such notice, an “Initial Option Notice”). Alnylam shall include in each such Initial Option Notice::

(a) a letter indicating which Option(s) is(are) applicable to the Option Product;

(b) the Initial Option Data Package for the Option Product (and all such data therein shall be made available to Genzyme through an electronic data room promptly following the date that such Initial Option Notice is delivered); and

Within [***] days after Genzyme’s receipt of an Initial Option Notice, Genzyme shall acknowledge receipt of such Initial Option Notice in writing to Alnylam or be deemed to have acknowledged such receipt as of such date. For clarity, if Genzyme requests the delivery of an Initial Option Notice with respect to ALN-AS1 or a Global Option Product prior to the time determined in accordance with clause (x) of this Section 3.3.1, Alnylam shall only be obligated to provide such information in the Initial Option Data Package as is available to Alnylam as of the date of such request from Genzyme.

3.3.2. Initial Evaluation Period. If an Initial Option Notice is delivered by Alnylam to Genzyme pursuant to clause (x) of Section 3.3.1 (Initial Option Package) (i.e., after an Option Product achieves Human POP Completion), then, if Genzyme desires to preserve its right to exercise an Option for such Option Product, Genzyme shall notify Alnylam in writing of Genzyme’s desire to exercise an Option and the type of Option that Genzyme desires to exercise (an “Option Preservation Notice”) prior to the expiration of the Initial Evaluation Period with respect to such Option Product. If Genzyme delivers an Option Preservation Notice to Alnylam prior to the expiration of the Initial Evaluation Period for an Option Product, then Section 3.3.3 (Effect of Option Preservation) shall apply. If Genzyme does not deliver an Option Preservation Notice to Alnylam prior to the expiration of the Initial Evaluation Period for an Option Product, then such Option Product shall be treated for all purposes under this Master Agreement, including Section 3.5 (Option Not Exercised), as an Option Product in respect of which Genzyme did not deliver an Exercise Notice to Alnylam.

3.3.3. Effects of Option Preservation. If Genzyme delivers an Option Preservation Notice prior to the expiration of the Initial Evaluation Period for an Option Product pursuant to Section 3.3.2 (Initial Evaluation Period), then the provisions of this Section 3.3.3 shall apply.

3.3.3.1. Final Option Data Package. Within [***] days after the earlier of [***], Alnylam shall complete all activities necessary for Alnylam to prepare a complete Final Option Data Package for the applicable Option Product and deliver such Final Option Data Package to Genzyme. Within [***] days after Genzyme’s receipt of a Final Option Data Package, Genzyme shall acknowledge receipt of such Final Option Data Package in writing to Alnylam or be deemed to have acknowledged such receipt as of such date. Notwithstanding the foregoing, Alnylam shall not deliver a Final Option Data Package to Genzyme unless and until all of the activities necessary to generate the information to be included in such Final Option Data Package have been completed.

3.3.3.2. Governance. At Genzyme’s request following the delivery of an Option Preservation Notice for an Option Product, the Parties shall form the committee that would be responsible for facilitating the Collaboration with respect to such Option Product under the applicable License Terms if Genzyme

exercised the Option identified in such Option Preservation Notice (i.e. if the identified Option is the Global Option, the Parties will form the JTT described in Section 5.1 (Joint Transition Team) of the Global License Terms; and if the identified Option is the Co-Co/Global Option, the Regional Option, the 2019 Trailing Regional Option or the 2021 Trailing Regional Option, the Parties will form the PJSC described in Section 5.1 (Product Joint Steering Committee) of the Co-Co License Terms or Section 5.1 (Product Joint Steering Committee) of the Regional License Terms, as applicable). Such committee shall have the responsibilities allocated to such committee under the applicable License Terms, except that such committee shall serve solely in an advisory committee and shall not have any decision-making authority with respect to the applicable Option Product unless and until Genzyme exercises an Option with respect to such Option Product. Such committee shall be disbanded if Genzyme does not exercise an Option with respect to the applicable Option Product prior to the end of the Option Exercise Period for such Option Product.

3.3.3.4. No Rights. Except for the right to exercise an Option in respect of an Option Product following receipt of a Final Option Data Package in respect thereof, Genzyme shall not obtain any ownership interest or other right to Develop or Commercialize (or to compel Alnylam Develop or Commercialize) such Option Product during the Transition Period, provided that the foregoing shall not relieve Alnylam of any of its obligations under this Master Agreement in respect of such Option Product during the Transition Period.

(a) Notice of Missing Information. Following receipt of an Option Data Package, Genzyme shall have [***] days to notify Alnylam if such Option Data Package is missing any information, which notice shall describe the information that is missing. Alnylam shall provide Genzyme with such missing information identified in such notice as soon as reasonably practicable (if and to the extent that such information is available to Alnylam).

(b) Disputed Missing Information. If, notwithstanding any information subsequently delivered by Alnylam pursuant to Section 3.3.4.1(a) (Notice of Missing Information), Genzyme, acting in good faith, still believes that the Option Data Package is missing material information, then Genzyme shall have the right to request that the AJSC review the Option Data Package (including any information subsequently delivered by Alnylam pursuant to Section 3.3.4.1(a) (Notice of Missing Information) or Section 3.3.4.2 (Supplements to Option Data Package)) within [***] days and determine whether material information is then missing from such Option Data Package. The AJSC is hereby empowered to compel Alnylam to produce any missing material information (if and to the extent that such information is available to Alnylam) within [***] days of such order.

3.3.4.2. Supplements to Option Data Package. Following delivery of an Option Data Package, Alnylam shall have the right to provide supplemental updates to any of the information included in such Option Data Package. In addition, Alnylam shall be required to promptly provide supplemental update(s) to Genzyme if [***]. In either such case, any such supplemental information shall be deemed to constitute a part of such Option Data Package for all purposes of this Collaboration Agreement (and to supersede previously provided information, to the extent such supplement information is identified, or would reasonably be apparent to Genzyme, as superseding previously provided information [***].

3.3.4.3. Information Sharing during Initial Evaluation Period and Option Exercise Period. During the Option Exercise Period (including, if applicable, the Initial Evaluation Period) for an Option Product, Alnylam shall (a) promptly provide to Genzyme (i) any patent, regulatory or CMC information, (ii) any material, complete sets of preclinical or clinical data and (iii) raw data tables, in each case ((i), (ii) and (iii)) then available to Alnylam that Genzyme may reasonably request, to the extent that such information was not previously provided by Alnylam to Genzyme and subject to customary and reasonable due diligence procedures to preserve the confidential nature of any such information, regarding such Option Product to assist Genzyme in deciding whether to exercise an Option for such Option Product if and when any such Option becomes exercisable, and (b) afford to Genzyme and its representatives reasonable access during normal business hours to Alnylam’s personnel, in each case ((a) and (b)) that Genzyme may reasonably request regarding such Option Product to assist Genzyme in deciding whether to exercise the Option for such Option Product, to the extent that such information was not previously provided by Alnylam to Genzyme.

3.3.4.4. Extension of Initial Evaluation Period and Option Exercise Period. If any information is provided to Genzyme following the receipt of an Option Data Package pursuant to Section 3.3.4.1 (Incomplete Data Option Package), 3.3.4.2 (Supplements to Option Data Package) or 3.3.4.3 (Information Sharing During Option Exercise Period) and such information is, in Genzyme’s reasonable discretion, material information not previously provided to Genzyme relating to the applicable Option Product, the Initial Evaluation Period or Option Exercise Period, as applicable, shall, if necessary and upon notice from Genzyme to Alnylam, be extended such that there is at least [***] days between Genzyme’s receipt of such material information and the expiration of such Initial Evaluation Period or Option Exercise Period, provided that in no event shall any Initial Evaluation Period or Option Exercise Period be extended by more than [***] days in the aggregate.

3.3.5. Information Excluded from Option Data Packages. Notwithstanding anything in this Master Agreement to the contrary, Alnylam shall not be obligated to include in any Option Data Package or to disclose pursuant to Section 3.3.4 (Updates to Option Data Packages) any information the disclosure of which would (i) in the reasonable opinion of Alnylam’s counsel, adversely affect the attorney-client privilege between Alnylam and its counsel or (ii) [***], and the exclusion of such information from any Option Data Package, as applicable, shall not constitute missing information for purposes of Section 3.3.4.1 (Incomplete Option Data Package), render the Option Data Package deficient in any respect or otherwise result in Genzyme having any right or claim against Alnylam. If material information may be excluded from any Option Data Package pursuant to clause (i) in the immediately preceding sentence, the Parties will enter into a common interest agreement designed to preserve such privilege and, after execution of such agreement, Alnylam will provide Genzyme with access to such information.

3.4. Exercise of an Option. Genzyme shall exercise an Option, if at all, by properly delivering a complete Exercise Notice in respect of such Option to Alnylam at any time during the respective Option Exercise Period for such Option.

3.4.2.1. Except as provided in Section 3.4.2.3, in the event that Genzyme exercises an Option for an Option Product for which an Option Preservation Notice was delivered pursuant to Section 3.3.2 (Initial Evaluation Period), then Genzyme may only exercise the Option identified in such Option Preservation Notice for such Option Product.

3.4.2.2. Except as provided in Section 3.4.2.3, if Genzyme identified the Global Option or the Additional Global Option as the Option it was preserving in an Option Preservation Notice and Genzyme does not deliver to Alnylam an Exercise Notice with respect to the exercise of such Option prior to the expiration of the applicable Option Exercise Period, then such Option shall terminate in full at the end of the Option Exercise Period and Genzyme shall not thereafter be permitted to exercise such unexercised Global Option or Additional Global Option, as applicable (such failure to deliver an Exercise Notice, a “Global/Additional Global Option Forfeiture”).

3.4.2.3. Notwithstanding the foregoing, if prior to the expiration of the Option Exercise Period for an Option Product (i) Genzyme receives material (a) clinical, GLP toxicology or nonclinical data or (b) regulatory guidance or a regulatory determination involving such Option Product, including in the Final Option Data Package, that was not included in (or, in the case of clause b, reasonably ascertainable from) the Initial Option Data Package or information presented to the AJSC or the PAC (and reflected in the written meeting minutes thereof) (such new data, regulatory guidance or a regulatory determination, “New Information”) and (ii) such New Information is adversely material to the expected clinical or commercial success of such Option Product such that Genzyme would not have exercised the Global Option or Additional Global Option if it possessed such New Information at the time it delivered such Option Preservation Notice, then Genzyme shall have the right (but not the obligation) to deliver an Option Exercise Notice to exercise a Regional Option during the applicable Option Exercise Period or it may elect not to exercise any Option with respect to such Option Product and, in either such case, Genzyme’s failure to exercise the Global Option or the Additional Global Option, as applicable, shall not constitute a Global/Additional Global Option Forfeiture and the Global Option or Additional Global Option, as applicable shall remain exercisable.

3.4.2.4. If development milestone(s) become payable under any License Terms, including because an Option Product is dosed in a patient in a Phase III Study, prior to the expiration of the Option Exercise Period for such Option Product and Genzyme exercises an Option in respect of such Option Product and such Option Product becomes a Collaboration Product, then Genzyme shall promptly, and in any event within [***] days following receipt of an invoice, pay such development milestone(s) to Alnylam as though such Option Product was a Collaboration Product at the time such development milestone(s) became payable Alnylam.

3.4.3. Regional Options. On the applicable Option Exercise Date for the exercise of any Regional Option, 2019 Trailing Regional Option or 2021 Trailing Regional Option, the applicable Regional Option Product or Trailing Regional Option

3.4.6. Development and Commercialization Following Option Exercise. Following the Option Exercise Date for a Collaboration Product, the Development and Commercialization of such Collaboration Product shall thereafter be governed by the applicable License Terms.

3.5. Option Not Exercised. If Genzyme does not deliver to Alnylam an Exercise Notice, or if Genzyme elects and delivers written notice to Alnylam to terminate an Option, with respect to an Option Product prior to the expiration of the applicable Option Exercise Period, then Genzyme’s Option with respect to such Option Product shall expire, Genzyme’s other rights

with respect to such Option Product (including any rights under Section 4 (Development and Pharmacovigilance) and Section 5 (Collaboration Management)), shall lapse, and Alnylam shall thereafter be free to Develop, Manufacture or Commercialize, alone or with one or more Third Parties, such Option Product, in each case without any further obligation to Genzyme. In addition, so long as Alnylam continues to actively Develop an Option Product following the expiration of Genzyme’s Option or Alnylam grants any rights to an Option Product to a Third Party, then other siRNAs Developed by Alnylam or any such Third Party (or its licensees or sublicensees, through multiple tiers) that target the same human gene as such Option Product (except for siRNAs described in clause (ii) of Section 1.2.21 (ALN-AT3) or clause (ii) of Section 1.2.20 (ALN-AS1) if any such siRNA is potentially subject to the Co-Co/Global Option) shall not be considered Option Products for purposes of this Master Agreement and Genzyme shall not have any Option hereunder with respect to such other siRNAs; provided, however, that if Alnylam ceases active Development of such Option Product, then the other siRNAs that target the same human gene as such Option Product shall again be considered Option Products for the purposes of this Master Agreement. [***].

3.6.1. Exclusivity for Core Pipeline Programs. Subject to Section 13.16.2 (Future Acquisition of a Party or its Business), during the Option Period, Alnylam and its Affiliates shall not enter into any agreement with any Third Party that grants such Third Party any rights with respect to any Core Pipeline Program that would be in conflict with the Collaboration Agreement following an siRNA becoming a Collaboration Product under the Collaboration Agreement, provided that this restriction shall not apply to:

3.6.1.1. following the expiration of the Option Exercise Period for an Option Product, an agreement with a Third Party that grants such Third Party rights with respect to such Option Product and other siRNAs that target the same human gene as such Option Product;

3.6.1.2. an agreement with a Third Party that grants such Third Party rights with respect to any Named Pipeline Program (excluding ALN-TTR02, ALN-TTRsc, ALN-AT3 and ALN-AS1) solely in the Alnylam Territory, provided that Alnylam complies with the provisions of Section 3.6.3 (ROFN for Available Third Party Rights) and 3.6.4 (Permitted Third Party Agreements);

3.6.1.3. following the exercise of the Co-Co/Global Option with respect to either Co-Co/Global Option Product, an agreement with a Third Party that grants such Third Party rights with respect to the other Co-Co/Global Option Product solely in the Alnylam Territory, provided that Alnylam complies with the provisions of Section 3.6.3 (ROFN for Available Third Party Rights) and 3.6.4 (Permitted Third Party Agreements); or

3.6.1.4. following the exercise of the Global Option, an agreement with a Third Party that grants such Third Party rights with respect to any Core Pipeline Program solely in the Alnylam Territory, provided that Alnylam complies with the provisions of Section 3.6.3 (ROFN for Available Third Party Rights) and 3.6.4 (Permitted Third Party Agreements).

3.6.2. Other Exclusivity Requirements in License Terms. Upon the exercise of any Option (which will cause an Option Product to become a Collaboration Product), the exclusivity provisions set forth in the applicable License Terms will go into effect with respect to such Collaboration Product.

3.6.3. ROFN for Available Third Party Rights. If Alnylam desires to enter into an agreement described in Section 3.6.1.2, 3.6.1.3 or 3.6.1.4, other than in accordance with Section 4.4 (Third Parties), then Alnylam shall so notify Genzyme in writing, which notice shall describe the rights that Alnylam intends to grant to a Third Party pursuant to such agreement (the “Available Third Party Rights”). Genzyme shall have [***] days from receipt of such written notice to notify Alnylam in writing as to whether Genzyme desires to negotiate for such Available Third Party Rights (a “ROFN Exercise Notice”). If Genzyme delivers a ROFN Exercise Notice prior to the expiration of such [***]-day period, Genzyme shall have the exclusive right for [***] days following the date that Genzyme delivers a ROFN Exercise Notice (the “ROFN Offer Period”) to negotiate with Alnylam and to make one or more written non-binding offers to Alnylam concerning the terms on which Genzyme would enter into an agreement to acquire the Available Third Party Rights (a “ROFN Non-Binding Offer”). If Genzyme delivers a ROFN Non-Binding Offer to Alnylam prior to the expiration of the ROFN Offer Period, Genzyme shall thereafter have the exclusive right for [***] days (or such longer period as may be mutually agreed by the Parties) (the “ROFN Negotiation Period”), to finalize and enter into a definitive agreement with Alnylam for the acquisition of such Available Third Party Rights. Alnylam shall not, during the ROFN Offer Period or Negotiation Period, enter into discussions, exchange information, or otherwise negotiate with any Third Party with respect to any of the Available Third Party Rights. If (i) Genzyme does not provide a ROFN Exercise Notice within [***] days of receiving notice of Available Third Party Rights, (ii) Genzyme does not provide a ROFN Non-Binding Offer prior to the expiration of the ROFN Offer Period, or (iii) the Parties do not execute a definitive agreement with respect to the Available Third Party Rights prior to the expiration of the ROFN Negotiation Period, then Alnylam shall be free to enter into an agreement with any Third Party with respect to such Available Third Party Rights (any such agreement, a “Permitted Third Party Agreement”), provided that, during the period of [***] months after the later of the expiration of the ROFN Offer Period or expiration of the ROFN Negotiation Period, Alnylam shall not enter into a Permitted Third Party Agreement with respect to such Available Third Party Rights on terms that are, in the aggregate, materially more favorable to such Third Party than the

last terms offered in writing by Genzyme to Alnylam during the ROFN Offer Period or ROFN Negotiation Period, as applicable, unless (a) Alnylam first re-offers to enter into an agreement with Genzyme on such more favorable terms and Genzyme does not accept such offer and enter into such agreement with Alnylam within [***] days after such re-offer. For clarity, prior to the ROFN Offer Period and ROFN Exercise Period with respect to any Available Third Party Rights, Alnylam shall be free to engage in discussions and exchange information with Third Parties with respect to such Available Third Party Rights, but shall not enter into any binding agreement with any Third Party with respect to such Available Third Party Rights.

3.6.4. Permitted Third Party Agreements. If Alnylam enters into a Permitted Third Party Agreement pursuant to Section 3.6.3 (ROFN For Available Third Party Rights) with respect to any Regional Option Product, such Permitted Third Party Agreement shall be compliant with Alnylam’s obligations under, and consistent with the terms of, the Regional License Terms.

3.6.5. Gate-Keeping. Promptly following the Effective Date, Alnylam shall establish a commercially reasonable mechanism to ensure that it does not grant any Third Party any rights with respect to a Core Pipeline Program in violation of Section 3.6.1 (Exclusivity for Core Pipeline Programs), whether pursuant to a new agreement or an amendment to, or any action or inaction pursuant to, any agreement between a Third Party and Alnylam that is in effect on the Effective Date.

6.1. ALN-TTR02 Supply Agreements. Subject to the terms and conditions of this Section 6 (Manufacture and Supply of the Collaboration Products), within [***] days after receiving written notice from Genzyme requesting such negotiations, the Parties will negotiate in good faith and enter into a supply agreement (and any other necessary ancillary agreements) for clinical supply of ALN-TTR02 by Alnylam (or for Alnylam by Alnylam’s Third Party manufacturer) (the “ALN-TTR02 Clinical Supply Agreement”), which will be consistent with the terms set forth on Schedule 6.1. In addition, at the request of Genzyme at least [***] months in advance of the first Regulatory Approval of ALN-TTR02 in the Genzyme Territory, the Parties will negotiate in good faith and enter into a supply agreement (and any other necessary ancillary agreements), before such [***]-month date, for commercial supply of ALN-TTR02 by Alnylam (or for Alnylam, by Alnylam’s Third Party manufacturer) (the “ALN-TTR02 Commercial Supply Agreement”), which will also be consistent with the terms set forth on Schedule 6.1. Notwithstanding the foregoing, the breach of any such Manufacturing terms as applied to a Collaboration Product shall be treated as a breach under the Regional License Terms, and not under this Master Agreement. When the Parties enter into an ALN-TTR02 Clinical Supply Agreement or ALN-TTR02 Commercial Supply agreement, such agreement will supersede the terms set forth in Schedule 6.1 with respect to Manufacture and supply of ALN-TTR02.

6.2. Collaboration Product Supply Agreements. Subject to the terms and conditions of this Section 6 (Manufacture and Supply of the Collaboration Products), following the Implementation Date with respect to any given Collaboration Product other than ALN-TTR02, and within [***] days following a written notice by Genzyme requesting such negotiation, the Parties will negotiate in good faith and enter into a supply agreement (and any other necessary ancillary agreements) for clinical supply of such Collaboration Product by Alnylam (or for Alnylam by Alnylam’s Third Party manufacturer) (each, a “Clinical Supply Agreement”), which will be consistent with the terms set forth on Schedule 6.2. In addition, at least [***] months in advance of the first Regulatory Approval of each Collaboration Product (other than ALN-TTR02) the Parties will negotiate in good faith and enter into a supply agreement (and any other necessary ancillary agreements), before such [***]-month date, for commercial supply of such Collaboration Product by Alnylam (or for Alnylam by Alnylam’s Third Party manufacturer) (each, a “Commercial Supply Agreement”), which will also be consistent with the terms set forth on Schedule 6.2; provided, however, in the case of any Global Licensed Product, the Parties shall only negotiate and enter into a Commercial Supply Agreement at the request of Genzyme. Notwithstanding the foregoing, the breach of any such Manufacturing terms as applied to a Collaboration Product shall be treated as a breach under its respective License Terms, and not under this Master Agreement. When the Parties enter into a Clinical Supply Agreement or Commercial Supply Agreement, such agreement will supersede the terms set forth in Schedule 6.2 with respect to the Manufacture and supply of the applicable Collaboration Product.

6.3. General Supply Agreement Requirements. In addition to reflecting terms consistent with those set forth on Schedule 6.1 or Schedule 6.2, as applicable, each Alnylam Supply Agreement will include key performance indicators for Alnylam (including criteria regarding Manufacturing capacity, quantity, timeliness of delivery, quality and cost that are consistent with prevailing industry standards for Third Party contract manufacturing agreements) (collectively, the “KPIs”). Further, for each Alnylam Supply Agreement for a given Collaboration Product, the Parties shall also enter into a quality technical agreement, which will be designed to ensure sufficient oversight by Genzyme of quality matters related to the Manufacture and testing of such Collaboration Product by Alnylam and its Third Party manufacturers and will set forth the quality responsibilities and obligations of both Genzyme and Alnylam.

6.4. Disputed Supply Agreement Terms. If the Parties are unable to reach agreement on any terms of any of the Alnylam Supply Agreements, as required by Sections 6.1 (ALN-TTR02 Supply Agreements), 6.2 (Collaboration Product Supply Agreements) and 6.3 (General Supply Agreement Requirements), then any such disputed terms shall be submitted to the AJSC for resolution pursuant to Section 5.1.8 (Decision-Making). If the AJSC is unable to resolve any such disputed terms, then those unresolved disputed terms shall be [***].

6.7. Third Party Manufacturers and Subcontracting. If, following the Effective Date, either Party desires to enter into an agreement with a Third Party manufacturer for the supply of Product, then (a) the other Party shall have the right to review and approve (such approval not unreasonably withheld, conditioned or delayed) such Third Party manufacturer and (b) each Party shall keep the other Party reasonably informed through the Manufacturing Committee of the status of any proposed supply agreement to be entered into with any such Third Party manufacturer with respect to the Manufacture and supply of such Product (a “Third Party Supply Agreement”) and submit any such Third Party Supply Agreement to the Manufacturing Committee for review and good faith discussion prior to its execution. For the avoidance of doubt, if a Party is subject to an existing binding agreement with a Third Party manufacturer for the supply of Product as of the Effective Date (each an “Existing Third Party Supply Agreement”), then, provided that such existing binding agreement is not materially amended at any time following the Effective Date (i) such existing binding agreement shall be deemed a Third Party Supply Agreement and (ii) the provisions of clauses a and b (immediately above) shall not apply to such existing binding agreement or the Third Party manufacturer party thereto. Without the consent of the other Party, but subject to the terms of this Section 6, either Party may subcontract (in whole or in part) its Manufacturing obligations under any Alnylam Supply Agreement or Genzyme Supply Agreement, as applicable, to a qualified Third Party manufacturer pursuant to a binding Third Party Supply Agreement; provided, however, that (A) the subcontracting Party shall remain solely responsible to the other Party for the performance of the subcontracting Party’s obligations under each Alnylam Supply Agreement or Genzyme Supply Agreement, as applicable and (B) the terms and/or conditions of any Third Party Supply

Agreement shall not in any way amend, modify or diminish the subcontracting Party’s obligations to the other Party under any Alnylam Supply Agreement or Genzyme Supply Agreement, as applicable. If the forecasting or order timing/method provisions of a Third Party Supply Agreement do not align with the corresponding provisions of a relevant Alnylam Supply Agreement or Genzyme Supply Agreement, as applicable, then, at the request of the subcontracting Party, the Parties shall discuss in good faith appropriate modifications to such Alnylam Supply Agreement or Genzyme Supply Agreement, as applicable, to bring the relevant provisions into alignment with such Third Party Supply Agreement, provided, however, that the non-subcontracting Party shall have no obligation to agree to any amendment to such Alnylam Supply Agreement or Genzyme Supply Agreement that can reasonably be expected to materially disadvantage the non-subcontracting Party.

6.8. Waivers. In the event that any Collaboration Product must be substantially Manufactured in the United States pursuant to applicable Law, then, at Genzyme’s request, Alnylam will use commercially reasonable efforts, at Genzyme’s expense, to secure a waiver of such requirement for such Collaboration Product under 35 U.S.C. § 204 or any analogous applicable Law outside the United States. If a waiver of the substantially manufactured requirement is obtained, then such Collaboration Product used or sold in the United States may be Manufactured as such waiver permits.

7.1.1. All Confidential Information disclosed by one Party to the other Party under the Collaboration Agreement, Stock Purchase Agreement and Investor Agreement shall be maintained in confidence by the receiving Party and shall not be disclosed to a Third Party or used for any purpose except as set forth herein without the prior written consent of the disclosing Party, except to the extent that such Confidential Information:

(a) is known by the receiving Party at the time of its receipt, and not through a prior disclosure by the disclosing Party, as documented by the receiving Party’s business records;

(b) is known to the public before its receipt from the disclosing Party, or thereafter becomes generally known to the public through no breach of the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement by the receiving Party;

(c) is subsequently disclosed to the receiving Party by a Third Party who is not known by the receiving Party to be under an obligation of confidentiality to the disclosing Party; or

(d) is developed by the receiving Party independently of Confidential Information received from the disclosing Party, as documented by the receiving Party’s business records.

7.1.2. Notwithstanding the obligations of confidentiality and non-use set forth above and in Section 7.1.3 below, a receiving Party may provide Confidential Information disclosed to it, and disclose the existence and terms of the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement as may be reasonably required in order to perform its obligations and to exploit its rights under the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement, and specifically to (i) Related Parties, and their employees, directors, agents, consultants, advisors or other Third Parties for the performance of its obligations hereunder (or for such entities to determine their interest in performing such activities) in accordance with the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement in each case who are under an obligation of confidentiality with respect to such information that is no less stringent than the terms of this Section 7.1; (ii) governmental or other Regulatory Authorities in order to obtain patents or perform its obligations or exploit its rights under the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement, provided that such Confidential Information shall be disclosed only to the extent reasonably necessary to do so; (iii) the extent required by Law, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or listing entity; (iv) any bona fide actual or prospective acquirers, underwriters, investors, lenders or other financing sources and any bona fide actual or prospective collaborators or strategic partners and to consultants and advisors of such Party, in each case who are under an obligation or confidentiality with respect to such information that is no less stringent than the terms of this Section 7.1; and (v) to Third Parties to the extent a Party is required to do so pursuant to the terms of an In-License. If a Party is required by Law to disclose Confidential Information that is subject to the non-disclosure provisions of this Section 7.1, such Party shall promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure. Notwithstanding Section 7.1.1, Confidential Information that is required to be disclosed by Law shall remain otherwise subject to the confidentiality and non-use provisions of this Section 7.1. If either Party concludes that a copy of any of the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement must be filed with the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States, such Party shall provide the other Party with a copy of such agreement showing any provisions hereof as to which the Party proposes to request confidential treatment, shall provide the other Party with an opportunity to comment on any such proposed redactions and to suggest additional redactions, and shall take such Party’s reasonable comments into consideration before filing such agreement.

7.1.3. Alnylam acknowledges that Genzyme may use Confidential Information of Alnylam for purposes of making investment and voting decisions with respect to the shares of Common Stock owned by Genzyme, provided that (i) Genzyme hereby acknowledges to Alnylam that Genzyme is aware that the United States securities laws prohibit any Person who has material, non-public information concerning a company from purchasing or selling securities of such company or from communicating such information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such securities and (ii) Genzyme hereby acknowledges that it is are aware of the sanctions under the United States securities laws attaching to misuse or such improper disclosure of any material, non-public information relating to Alnylam.

7.1.4. Each Party recognizes that the value to the other Party of the transactions under the Collaboration Agreement, Stock Purchase Agreement and Investor Agreement depend, in part, on each Party protecting the secrecy of its Know-How. Therefore, without limiting any Party’s right’s right to license its Know-How, subject to the terms of the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement, in any way it chooses, each Party shall use commercially reasonable efforts to protect the confidentiality of its Know-How as determined in such Party’s reasonable business judgment.

7.1.5. Notwithstanding any provision of the Collaboration Agreement to the contrary but subject to the occurrence of the Effective Date, Residual Knowledge shall not be considered Confidential Information for purposes of this Section 7.1.

7.2.1. Publication. Genzyme and Alnylam each acknowledge the other Party’s interest in publishing certain key results of the Collaboration. Each Party also recognizes the mutual interest in obtaining valid patent protection and in protecting trade secret information. Consequently, except for disclosures permitted pursuant to Section 7.1 (Nondisclosure Obligation) and 7.2.2 (Publicity), either Party wishing to make a publication or public presentation that contains the Confidential Information of the other Party shall deliver to the other Party a copy of the proposed written publication or presentation at least [***] days prior to submission for publication or presentation. The reviewing Party shall have the right (i) to propose modifications to the publication or presentation for patent reasons, trade secret reasons or business reasons, and the publishing Party shall remove all Confidential Information of the other Party if requested by the reviewing Party, or (ii) to request a reasonable delay in publication or presentation in order to protect patentable information. If the reviewing Party requests a delay, the publishing Party shall delay submission or presentation for a period of [***] days (or such shorter period as may be mutually agreed by the Parties) to enable the non-publishing Party to file patent applications protecting such Party’s rights in such

information. With respect to any proposed publications or disclosures by investigators or academic or non-profit collaborators, such materials shall be subject to review under this Section 7.2.1 to the extent that Genzyme or Alnylam, as the case may be, has the right and ability (after using commercially reasonable efforts to obtain such right and ability) to do so.

7.2.2. Publicity. Except as set forth in Section 7.1 (Nondisclosure Obligation) and Section 7.2.1 (Publication) above and 7.3.2 (Press Release) below, the terms of any of the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement may not be disclosed by either Party, and neither Party shall use the name, Trademark, trade name or logo of the other Party or its employees in any publicity, news release or disclosure relating to any of the Collaboration Agreement, Stock Purchase Agreement or Investor Agreement, its subject matter, or the activities of the Parties hereunder without the prior express written permission of the other Party, except as may be required by Law, including by the rules or regulations of the United States Securities and Exchange Commission, the French Financial Markets Authority, the French Prudential Supervisory Authority or similar regulatory agency in any country other than the United States or France or of any stock exchange or listing entity, or except as expressly permitted by the terms hereof.

7.3.1. Following the execution of the Collaboration Agreement, the Parties shall issue separate press releases in the forms set forth in Schedule 7.3 or such other forms mutually agreed by the Parties. After such initial press releases, except as provided in Section 7.3.2, neither Party shall issue a press release or public announcement relating to the Collaboration Agreement without the prior written approval of the other Party, which approval shall not be unreasonably withheld, conditioned or delayed, except that a Party may (i) once a press release or other public statement is approved in writing by both Parties, make subsequent public disclosure of the information contained in such press release or other written statement without the further approval of the other Party, and (ii) issue a press release or public announcement as required, in the reasonable judgment of such Party, by Law, including by the rules or regulations of the United States Securities and Exchange Commission, the French Financial Markets Authority, the French Prudential Supervisory Authority or similar regulatory agency in a country other than the United States or France or of any stock exchange or listing entity.

7.3.2. Notwithstanding anything in this Section 7.3 to the contrary, either Party may issue a press release or make a public disclosure relating to (i) the results of any Clinical Studies with respect to an Option Product, (ii) the exercise of an Option, (iii) the payment or receipt of a milestone payment under any License Terms with respect to a Collaboration Product and (iv) such Party’s Development, Manufacturing or Commercialization activities under any License Terms with respect to Collaboration

Products in such Party’s Territory, provided that such press release or public disclosure does not disclose Confidential Information of the other Party. Furthermore, either Party may issue a press release or make a public disclosure relating to the other Party’s Development, Manufacturing or Commercialization activities with respect to the Collaboration Products in the other Party’s Territory, provided that (i) such press release or public disclosure does not disclose Confidential Information of the other Party and (ii) such press release or public disclosure merely repeats subject matter previously disclosed by the other Party in a manner that is substantially consistent with such prior disclosure. Prior to making any such disclosure under this Section 7.3.2, however, the Party making the disclosure shall provide the other Party with a draft of such proposed disclosure a reasonable time (but at least [***] business days) prior to disclosure to allow the other Party to review and comment prior to making any such disclosure, for the other Party’s review and comment, and the disclosing Party shall consider in good faith any timely comments provided by the other Party. Notwithstanding the foregoing, except as expressly permitted by clause (i), (ii) or (iii) above and subject to clause (ii) of Section 7.3.1, Alnylam may not issue any other press release or make a public disclosure relating to Genzyme’s activities for any Global Licensed Product without the prior written consent of Genzyme.

8.4.2. Clarifying Amendments. [***]. For clarity, such amendment will be an Existing Alnylam In-License for all purposes of the Collaboration Agreement.

8.4.3. Retention of Title. During the Option Period, Alnylam shall retain and maintain sufficient legal and/or beneficial title and ownership of, or sufficient license rights under, any Option Product Technology relating to a Core Pipeline Program to enable Alnylam to grant the licenses and rights to such Option Product Technology that would be granted to Genzyme under, and as reasonably necessary to practice, such Option Product Technology under the applicable License Terms if Genzyme exercised an Option with respect to such Option Product. Without limiting the generality of the foregoing, during the Option Period, Alnylam shall not sell, transfer, lease or otherwise dispose of any Option Product Technology, except to the extent expressly permitted under the Collaboration Agreement or to grant a security interest, lien or other encumbrance in, on or to any Option Product Technology as part of a financing transaction.

8.4.4. Know-How. Alnylam shall not use any Know-How that it does not Control in the Development or Manufacture of Option Products from the Core Pipeline Programs. Alnylam shall obtain sufficient legal or beneficial title and ownership of, or beneficial title and ownership of, or sufficient rights under, and as reasonably necessary to practice, any Know-How that is used by Alnylam in the Development or Manufacture of Option Products from the Core Pipeline Programs to grant the licenses and rights to such Know-How that would be granted to Genzyme pursuant to the applicable License Terms if Genzyme exercised an Option with respect to an Option Product from the Core Pipeline Programs.

8.4.5. In-Licenses. Alnylam shall use commercially reasonable efforts to maintain Control of all Know-How and Patent Rights licensed to Alnylam under the Existing Alnylam In-Licenses and Additional Alnylam In-Licenses that would be necessary or useful for Genzyme to Develop, Manufacture and/or Commercialize any Option Product in the Field in the Genzyme Territory pursuant to the License Terms that

would apply to such Option Product if Genzyme exercised an Option for such Option Product. Alnylam shall use commercially reasonable efforts not to materially breach or be in material default under any of its obligations under any Alnylam In-License. Alnylam will not voluntarily amend or terminate any Alnylam In-License in a manner that would terminate rights that would be sublicensed to Genzyme if Genzyme exercised an Option with respect to an Option Product, other than Additional Alnylam In-Licenses. Alnylam will update Schedule 1.2.82 (Existing Alnylam In-Licenses) if, prior to the Effective Date, Alnylam enters into any agreement pursuant to which Alnylam Controls Patent Rights or Know-How necessary or useful to Develop, Manufacture or Commercialize any Option Product (where such term is limited for these purposes in accordance with the last sentence of Section 8.2), ALN-TTR02 or ALN-TTRsc in the Field in the Genzyme Territory.

8.4.6. No Debarment. Each Party shall commercially reasonable efforts to not use, in any capacity in connection with the Collaboration or the performance of its obligations under the Collaboration Agreement, any Person that has been debarred pursuant to Section 306 of the United States Federal Food, Drug, and Cosmetic Act, as amended, or that is the subject of a conviction described in such section. Each Party agrees to inform the other Party in writing immediately if it or any Person that is performing activities in the Collaboration or under the Collaboration Agreement, is debarred or is subject to debarment or is the subject of a conviction described in Section 306, or if any action, suit, claim, investigation or legal or administrative proceeding is pending or, to the best of the notifying Party’s knowledge, is threatened, relating to the debarment or conviction of the notifying Party or any Person or entity used in any capacity by such Party or any of its Affiliates in connection with the Collaboration or the performance of its other obligations under the Collaboration Agreement.

8.4.10. Contractual Obligations. If any ALN-TTR Technology or Option Product Technology is subject to any funding agreement with any government or Governmental Authority or subject to any other agreement under which requirements and obligations will apply to Genzyme under the Collaboration Agreement, then, at Genzyme’s request, Alnylam will use commercially reasonable efforts, at Genzyme’s expense, to secure a waiver of any requirements or obligations of Genzyme under such agreements.

9.1. Reports; Payment of Royalty. During the Term, following the First Commercial Sale of any Collaboration Product by or on behalf of a Party in such Party’s Territory under the applicable License Terms, such Party shall furnish to the other Party a written report within [***] days after the end of each Calendar Quarter showing, on a Collaboration Product-by-Collaboration Product and country-by-country basis [***]. Except as expressly provided in the Collaboration Agreement, all payments by one Party to the other Party under the Collaboration Agreement shall be non-refundable and non-creditable and not subject to set-off. Royalties shown to have accrued by each royalty report shall be due and payable [***] days following the date such royalty report is due. In addition, each Party selling a Collaboration Product shall prepare and deliver to the other Party any additional reports for sales in such selling Party’s Territory as required under any applicable Existing Genzyme In-Licenses, Existing Alnylam In-Licenses or Collaboration In-Licenses.

9.2.1. On a Collaboration Product-by-Collaboration Product basis, upon the written request of a Party and not more than once in each Calendar Year, the other Party and its Related Parties shall permit an independent certified public accounting firm of internationally-recognized standing selected by the requesting Party and reasonably acceptable to the other Party, at the requesting Party’s expense except as set forth below, to have access during normal business hours to such of the records of the other Party as may be reasonably necessary to verify the accuracy of the royalty and other amounts payable or reports under the Collaboration Agreement in respect of such Collaboration Product (including Global R&D Costs (as defined in any of the License Terms) and Cost of Goods but excluding S&M Costs (as defined in the Co-Co License Terms)) for any year ending not more than [***] years prior to the date of such request for the sole purpose of verifying the basis and accuracy of payments made under the applicable License Terms in respect of such Collaboration Product. Notwithstanding the foregoing, a Party may not make more than [***] in a Calendar Year, [***].

9.2.2. If such accounting firm identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy, together with late-payment interest in accordance with Section 9.4 (Late Payments), within [***] days after the date the requesting Party delivers to the other Party such accounting firm’s written report so concluding, or as otherwise agreed by the Parties in writing. The fees charged by such accounting firm shall be paid by the requesting Party, unless such discrepancy represents an underpayment by the other Party of at least [***], on a Collaboration Product-by-Collaboration Product basis, of the total amounts due in respect of such Collaboration Product in the audited period, in which case such fees shall be paid by the other Party.

9.2.3. Each Party shall comply with all applicable audit requirements in the In-Licenses and shall include in each sublicense granted by it pursuant to the License Terms a provision requiring any Sublicensee (as defined under the applicable License Terms) to make reports to the Party that is party to such In-License, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by the independent accountant of the Party that is party to such In-License to the same extent required of a Party under the Collaboration Agreement.

9.2.4. Unless an audit for such year has been commenced prior to and is ongoing upon the [***] anniversary of the end of such year, the calculation of royalties, expense reimbursement and other payments payable with respect to such year shall be binding and conclusive upon both Parties, and each Party and its Related Parties shall be released from any further liability or accountability with respect to such royalties or expense reimbursement for such year.

9.2.5. Each Party shall treat all financial information subject to review under this Section 9.2 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of Section 7 (Confidentiality and Publication), and shall cause its accounting firm to enter into a confidentiality agreement with the other Party or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement, which terms shall be no less stringent than the provisions of Section 7 (Confidentiality and Publication).

9.3. Payment Exchange Rate. All payments to be made under the Collaboration Agreement shall be made in United States dollars and shall be paid by bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by the receiving Party from time to time. In the case of Net Sales made or expenses incurred by a Party and its Related Parties in currencies other than United States dollars during a Calendar Quarter, the rate of exchange to be used in computing the amount of United States dollars due shall be the rate of exchange utilized by such Party in its worldwide accounting system and calculated in accordance with GAAP.

9.4. Late Payments. Any amount owed by a Party to the other Party under the Collaboration Agreement that is not paid on or before the date such payment is due shall bear interest at a rate per annum equal to the lesser of (a) [***] or (b) the highest rate permitted by Law, calculated on the number of days such payments are paid after such payments are due and compounded monthly.

9.5. Blocked Payments. If, by reason of Laws in any jurisdiction in a Party’s Territory, it becomes impossible or illegal for a Party to transfer milestone payments, royalties or other payments under the Collaboration Agreement to the other Party, the payor shall promptly notify the payee. During any such period described above, the payor shall deposit such payments in local currency in the relevant jurisdiction to the credit of the payee in a recognized banking institution designated by the payee or, if none is designated by the payee within a period of [***] days, in a recognized banking institution selected by the payor and identified in a written notice given to the payee.

9.6. Taxes. If a timely and appropriately completed and executed Internal Revenue Service Form W-9 is provided by the receiving Party to the paying Party, the Parties acknowledge and agree that no United States tax withholding shall be applied with respect to any milestone payments due under any License Terms. Each Party shall use reasonable efforts to minimize tax withholding on payments made to the other Party. Notwithstanding such efforts, if such Party concludes that tax withholdings under the Laws of any country are required with respect to payments to the other Party, such Party shall first notify the other Party and provide such Party with [***] days to determine whether there are actions such receiving Party can undertake to avoid such withholding. During this notice period, the paying Party shall refrain from making such payment until the receiving Party instructs the paying Party that (a) the receiving Party intends to take actions (satisfactory to both Parties) that shall obviate the need for such withholding, in which case the paying Party shall make such payment only after it is instructed to do so by the receiving Party, or (b) the paying Party should make such payment and withhold the required amount and pay it to the appropriate Governmental Authority. In such case, the withholding Party shall promptly provide the other Party with copies of receipts or other evidence reasonably required and sufficient to allow the other Party to document such tax withholdings adequately for purposes of claiming foreign tax credits and similar benefits. The Parties shall cooperate reasonably in completing and filing documents required under the provisions of any applicable tax laws or under any other applicable Law, in connection with the making of any required tax payment or withholding payment, or in connection with any claim to a refund of or credit for any such payment. The Parties shall cooperate to minimize such taxes in accordance with applicable Laws, including using reasonable efforts to access the benefits of any applicable treaties. [***].

10.1. General Indemnification by Genzyme. Genzyme shall indemnify, hold harmless and defend Alnylam, its Related Parties, and their respective directors, officers, employees and agents (“Alnylam Indemnitees”) from and against any and all Third Party claims, suits, losses, liabilities, damages, costs, fees and expenses (including reasonable attorneys’ fees and litigation expenses) (collectively, “Losses”) arising out of or resulting from, directly or indirectly, (a) any breach of, or inaccuracy in, any representation or warranty made by Genzyme in the Collaboration Agreement, or any breach or violation of any covenant or agreement of Genzyme in or in the performance of the Collaboration Agreement, or (b) the negligence or willful misconduct by or of Genzyme and its Related Parties, and their respective directors, officers, employees and agents in the performance of Genzyme’s obligations under the Collaboration Agreement. Genzyme shall have no obligation to indemnify the Alnylam Indemnitees to the extent that the Losses arise out of or result from, directly or indirectly, any breach of, or inaccuracy in, any representation or warranty made by Alnylam in the

Collaboration Agreement, or any breach or violation of any covenant or agreement of Alnylam in or in the performance of the Collaboration Agreement, or the negligence or willful misconduct by or of any of the Alnylam Indemnitees, or matters for which Alnylam is obligated to indemnify Genzyme under Section 10.2 (General Indemnification by Alnylam) or 10.3 (Product Liability).

10.2. General Indemnification by Alnylam. Alnylam shall indemnify, hold harmless, and defend Genzyme, its Related Parties and their respective directors, officers, employees and agents (“Genzyme Indemnitees”) from and against any and all Losses arising out of or resulting from, directly or indirectly, (a) any breach of, or inaccuracy in, any representation or warranty made by Alnylam in the Collaboration Agreement, or any breach or violation of any covenant or agreement of Alnylam in or in the performance of the Collaboration Agreement, (b) the negligence or willful misconduct by or of Alnylam and its Related Parties, and their respective directors, officers, employees and agents in the performance of Alnylam’s obligations under the Collaboration Agreement or (c) any infringement (including induced infringement) of any of the Patent Rights identified on Schedule 10.2 (Identified Patent Rights) arising from the Development, Manufacture or Commercialization of a Collaboration Product by Genzyme or its Affiliates. Alnylam shall have no obligation to indemnify the Genzyme Indemnitees to the extent that the Losses arise out of or result from, directly or indirectly, any breach of, or inaccuracy in, any representation or warranty made by Genzyme in the Collaboration Agreement, or any breach or violation of any covenant or agreement of Genzyme in or in the performance of the Collaboration Agreement, or the negligence or willful misconduct by or of any of the Genzyme Indemnitees, or matters for which Genzyme is obligated to indemnify Alnylam under Section 10.1 (General Indemnification by Genzyme) or 10.3 (Product Liability).

10.3. Product Liability. Subject to any Supply Agreements, any Losses arising out of Third Party product liability claims arising from the Development or Commercialization of Collaboration Products shall be (a) borne by Genzyme, to the extent such Losses were incurred with respect to the Development or Commercialization by or on behalf of Genzyme or its Related Parties of a Regional Licensed Product in or for the Genzyme Territory, a Co-Co Licensed Product in or for the Genzyme Territory, or a Global Licensed Product anywhere in or for the world by or on behalf of Genzyme and its Related Parties, (b) be borne by Alnylam, to the extent such Losses were incurred with respect to Development or Commercialization of a Regional Licensed Product in or for the Alnylam Territory by or on behalf of Alnylam and its Related Parties, and (c) be borne fifty percent (50%) by each of Genzyme and Alnylam, to the extent such Losses were incurred with respect to Development or Commercialization by or on behalf of Alnylam or its Related Parties of a Co-Co Licensed Product in or for the Alnylam Territory. The Party bearing such Losses in accordance with the immediately preceding sentence shall indemnify, hold harmless and defend the other Party and its Related Parties and their respective directors, officers, employees and agents from and against such Losses.

10.4. Indemnification Procedure. In the event of any such claim against any Genzyme Indemnitee or Alnylam Indemnitee (individually, an “Indemnitee”), the indemnified Party shall promptly notify the other Party in writing of the claim and the indemnifying Party

shall manage and control, at its sole expense, the defense of the claim and its settlement. The Indemnitee shall cooperate with the indemnifying Party and may, at its option and expense, be represented in any such action or proceeding. The indemnifying Party shall not be liable for any settlements, litigation costs or expenses incurred by any Indemnitee without the indemnifying Party’s written authorization. Notwithstanding the foregoing, if the indemnifying Party believes that any of the exceptions to its obligation of indemnification of the Indemnitees set forth in Sections 10.1 (General Indemnification by Genzyme), 10.2 (General Indemnification by Alnylam) or 10.3 (Product Liability) may apply, the indemnifying Party shall promptly notify the Indemnitees, which shall then have the right to be represented in any such action or proceeding by separate counsel at their expense, provided that the indemnifying Party shall be responsible for payment of such expenses if the Indemnitees are ultimately determined to be entitled to indemnification from the indemnifying Party for the matters to which the indemnifying Party notified the Indemnitees that such exception(s) may apply.

10.5. Limitation of Liability. NEITHER PARTY HERETO SHALL BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF THE COLLABORATION AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THE COLLABORATION AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT AS A RESULT OF A PARTY’S WILLFUL MISCONDUCT OR A BREACH OF SECTION 3.6 (EXCLUSIVITY DURING OPTION PERIOD), SECTION 7 (CONFIDENTIALITY AND PUBLICATION), SECTION 10.4.1 OF THE CO-CO LICENSE TERMS (EXCLUSIVITY), SECTION 9.4.1 OF THE GLOBAL LICENSE TERMS (EXCLUSIVITY) OR SECTION 8.4.1 OF THE REGIONAL LICENSE TERMS (EXCLUSIVITY). NOTHING IN THIS SECTION 10.5 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY. NOTWITHSTANDING THE FOREGOING, ALNYLAM SHALL NOT BE LIABLE FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF ANY BREACH OF SECTION 3.6 (EXCLUSIVITY DURING OPTION PERIOD) UNLESS GENZYME BRINGS AN ACTION SEEKING SUCH DAMAGES WITHIN SIX (6) MONTHS AFTER THE EARLIER OF THE DATE ON WHICH THE TRANSACTION BETWEEN ALNYLAM AND A THIRD PARTY ENTERED INTO IN BREACH OF SECTION 3.6 (EXCLUSIVITY DURING OPTION PERIOD) FIRST BECOMES PUBLICLY KNOWN OR THE DATE ON WHICH ALNYLAM NOTIFIES GENZYME OF SUCH TRANSACTION.

10.6. Insurance. Each Party shall maintain insurance during the Term and for a period of at least two (2) years after the last commercial sale of any Collaboration Product generated under the Collaboration, with a reputable, solvent insurer in an amount appropriate for its business and products of the type that are the subject of the Collaboration Agreement, and for its obligations under the Collaboration Agreement. Specifically, each Party shall maintain product liability insurance and clinical trial liability insurance with limits of at least [***] per occurrence and in annual aggregate. Upon request, each Party shall provide the other Party with evidence of the existence and maintenance of such insurance coverage.

11.1. Prosecution and Maintenance of Patent Rights. Alnylam has the sole responsibility to, at Alnylam’s discretion and sole expense (except as provided below), file, conduct prosecution, and maintain (including the defense of any interference or opposition proceedings), all Patent Rights comprising Option Product Core Technology Patents and Option Product-Specific Patents, in Alnylam’s name. Notwithstanding the foregoing, Alnylam shall file Option Product-Specific Patents in the Genzyme Patent Jurisdictions and shall use commercially reasonable efforts to prosecute and maintain such Patent Rights in the Genzyme Patent Jurisdictions and shall timely pay all filing (including during the pendency of any Patent Right) and renewal fees payable with respect thereto [***].

11.2. Patent Prosecution Information Sharing. Alnylam shall consult with Genzyme, through the IP Committee, on its strategy for the preparation, filing, prosecution, and maintenance of the Option Product Patents and shall consider in good faith timely comments from Genzyme thereon. Alnylam shall furnish to Genzyme, through the IP Committee or via electronic mail or such other method as mutually agreed by the Parties, copies of documents received from outside counsel in the course of filing, prosecution or maintenance of or filed with the relevant national patent offices with respect to the filing, prosecution and maintenance of all Option Product Core Technology Patents and Option Product-Specific Patents within a reasonable time after filing of such documents.

11.3.1. Additional 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 Genzyme’s Commercialization of a Collaboration Product in the Genzyme Territory or Genzyme’s Manufacture or Development of such Collaboration Product in accordance with the applicable License Terms, 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 Genzyme under the applicable License Terms, effective as of the later of (a) the date the applicable Patent Right issues or (b) the date that Genzyme’s Commercialization of such Collaboration Product in the Genzyme Territory or Genzyme’s Manufacture of Development of such Collaboration Product in accordance with this Master Agreement and the applicable License Terms would infringe such Patent Right in the absence of a license thereunder from Alnylam.

11.3.2. Existing Alnylam In-Licenses. In the event that Alnylam fails to identify a Third Party agreement under which Alnylam Controls Know-How or Patent Rights that are necessary or useful to Develop, Manufacture or Commercialize a Collaboration Product, then the Parties will amend the Schedules to the applicable License Terms to include such agreements within the definition of Existing Alnylam In-License or Additional Alnylam In-License. In any event, any Potential Alnylam In-License under which Alnylam Controls Know-How or Patent Rights that are necessary or useful to Develop, Manufacture or Commercialize a Collaboration Product will be deemed to be an Existing Alnylam In-License regardless of whether it is entered into before or after the Implementation Date for such Collaboration Product.

11.3.3.1. Proposed In-Licenses. In the event that either Party desires to enter into an agreement with a Third Party pursuant to which such Party would acquire a license under any Patent Rights that are necessary or useful to Develop, Manufacture or Commercialize any Collaboration Product (a “Proposed In-License”), then such Party shall deliver a written notice to the other that may include the identity of such Third Party, a description of such Patent Rights and any proposed terms of such Proposed In-License (a “Proposed In-License Notice”) [***]. Within [***] days of delivery of the Proposed In-License Notice, the IP Committee shall meet to discuss the Proposed In-License and the proposing Party shall consider in good faith comments from the other Party. If the proposing Party enters into the Proposed In-License, and the non-proposing Party wishes to obtain a sublicense under such Proposed In-License, then the Proposed In-License shall be deemed to be a “Collaboration In-License” for all purposes under the Collaboration Agreement. For the sake of clarity, if the non-proposing Party does not wish to obtain a sublicense under a Proposed In-License, then none of the rights granted to the proposing Party thereunder will be deemed to be “Controlled” by the proposing Party and, if the proposing Party (or any of its sublicensees thereunder) has rights to enforce any Patent Rights licensed to the proposing Party thereunder, the proposing Party shall have the right to enforce such Patent Rights against the non-proposing Party.

11.3.3.2. Requirements for Collaboration In-Licenses. In entering into any Collaboration In-License (or Potential Alnylam In-License, in the case of Alnylam), each Party shall [***]. Any Patent Rights licensed to a Party under a Collaboration In-License shall be deemed to be Controlled by such Party for all purposes under the License Terms. The Party entering into a Collaboration In-License must notify the other Party promptly and provide the other Party with a copy of such Collaboration In-License.

(a) Except as provided under the Co-Co License Terms, Alnylam shall bear [***] of any Third Party License Payments that become payable during the Term under any (i) Existing Alnylam In-License or (ii) Potential Alnylam In-License that is entered into after the Execution Date that becomes an Existing Alnylam In-License pursuant to Section 11.3.2 (Existing Alnylam In-Licenses).

(b) Subject to Section 11.3.5 (Royalty Stacking), Genzyme shall bear [***] of any Third Party License Payments that become payable under any Existing Genzyme In-License or any Un-Blocking Genzyme In-License during the Term.

11.3.4.2. Collaboration In-Licenses. Any Third Party License Payment that becomes payable under any Collaboration In-License (other than a Potential Alnylam In-License) shall be allocated between the Parties as follows:

(a) if such Third Party License Payment becomes payable as a result of a Party’s activities under the License Terms with respect to a Collaboration Product and is either (i) [***] (a “Collaboration Product-Specific Payment”); and

(b) if such Third Party License Payment is not a Collaboration Product-Specific Payment, then [***].

(c) If the Parties cannot agree on whether a Third Party License Payment is a Collaboration Product-Specific Payment or not, or how to allocate a Third Party License Payment that is not a Collaboration Product-Specific Payment, the Parties shall submit the matter to the AJSC for resolution. If the AJSC cannot resolve the matter within [***] days of it being referred to them, the Parties shall submit the matter [***]. If the Party that is not a party to the Collaboration In-License disagrees with the allocation of a Third Party License Payment pursuant to this Section 11.3.4.2(c), then such Party may elect not to take a sublicense under such Collaboration In-License, in which case none of the rights granted to the other Party thereunder will be deemed to be “Controlled” by the other Party and, if the other Party has rights to enforce any Patent Rights licensed to such other Party thereunder, such other Party (or any of its sublicensees thereunder) shall have the right to enforce such Patent Rights against such Party.

11.3.4.4. To the extent not otherwise deducted from payments by one Party to the other Party when determining Net Sales of any Collaboration Product and without duplication of Genzyme’s rights under Section 11.3.5 (Royalty Stacking), either Party that advances any payment for which the other Party is actually responsible under this Section 11.3.4 shall invoice the other Party for such advanced amount on a quarterly basis. The Party receiving such invoice shall make payment of such amount to the invoicing Party within [***] days of the date of such invoice and otherwise in accordance with Section 9 (Royalty Reports; Payments; Audits) of this Master Agreement.

11.3.6. Amendments to In-Licenses. If a Party amends an In-License to which it is a Party in a manner that increases the royalty payable by the other Party under such In-License without the prior written consent of the other Party, such Party shall be solely responsible for any such additional payments due under such In-License.

11.3.7. Stand-by Licenses. Upon Genzyme’s reasonable request during the Term, Alnylam shall reasonably cooperate in good faith with Genzyme’s efforts to obtain stand-by license agreements related to any Collaboration Product with respect to any Alnylam In-License, pursuant to which, upon termination of the relevant In-License, Genzyme would receive a direct license from the applicable Third Party licensor under any Patent Rights and Know-How that are sublicensed to Genzyme pursuant to the Collaboration Agreement. Such stand-by license agreement will be in a form approved in advance by Alnylam. Any costs incurred by Alnylam in cooperating with Genzyme’s efforts to obtain any such stand-by license agreement shall be reimbursed by Genzyme.

11.3.8. Breach or Termination of In-Licenses.

12.3.3. Termination of Collaboration Agreement for Patent Challenge. Without limiting any other legal or equitable remedies that either Party may have, if the Collaboration Agreement is terminated by Alnylam pursuant to Section 12.2.4 (Challenges of Patent Rights) then (a) this Master Agreement and all Options granted to Genzyme hereunder shall terminate and (b) each of the License Terms shall terminate and the consequences of termination of the entire License Terms for cause by Alnylam set forth in each of the License Terms shall apply.

Unless otherwise agreed by the Parties, on a country-by-country basis, following the acceptance or approval of the IND and the first dosing of the first patient in the first Phase III Study of the relevant Regional Licensed Product in such country, as set forth in Section 3.1.1.1 above, Alnylam will assign the IND in such country in the Genzyme Territory to Genzyme and from that point forward, Genzyme will be primarily responsible for the related regulatory activities with respect thereto in its Territory. [***]

3.1.2. Communications. Each Party will notify the PJSC responsible for each Regional Licensed Product in writing, including a brief description in English, of the principal issues raised in each material communication with Regulatory Authorities with respect to such Regional Licensed Product within [***] days after receipt thereof. Upon request, each Party will provide to the other Party: (a) at the providing Party’s expense, a summary translation of such material communications in English, (b) at the providing Party’s expense, complete copies of the

original correspondence in their native language, or (c) at the requesting Party’s expense, a full translation of such material communications in English, in each case (a) through (c) within a reasonable period of time following such request. For the purposes of this Section 3.1, “material communications” with Regulatory Authorities include meetings with Regulatory Authorities and Regulatory Authority questions or concerns with respect to significant issues, including any of the following: key product quality attributes (e.g., purity), safety findings affecting the platform (e.g., Serious Adverse Events, emerging safety signals), clinical or nonclinical findings affecting patient safety, lack of efficacy or receipt or denial of Regulatory Approval.

3.1.3. Regulatory Meetings. Each Party shall provide the other Party with reasonable advance notice of all substantive meetings with the Government Authorities in its Territory pertaining to each Regional Licensed Product, and Alnylam shall provide Genzyme with reasonable advance notice of all substantive meetings with the Governmental Authorities in the Genzyme Territory pertaining to each Regional Licensed Product, or with as much advance notice as practicable under the circumstances. Each Party shall use reasonable efforts, to the extent reasonably practicable, to permit the other Party to have, at the other Party’s expense, mutually acceptable representatives of the other Party to attend, solely as a non-participating observer, material, substantive meetings, including pre-IND and end of Phase II Study meetings, with the Governmental Authorities within such Party’s Territory pertaining to such Regional Licensed Product; provided, however, that neither Party shall be obligated to change the schedule of such a meeting in order to accommodate the schedule of the other Party’s representatives. Prior to the acceptance or approval of the IND and the first dosing of the first patient in the first Phase III Study of a Regional Licensed Product by Alnylam in a country in the Genzyme Territory, Alnylam shall provide Genzyme with reasonable advance notice of all substantive meetings with Regulatory Authorities in the Genzyme Territory pertaining to such Regional Licensed Product, or with as much advance notice as practicable under the circumstances. Alnylam shall use reasonable efforts, to the extent reasonably practicable, to permit Genzyme to have, at Genzyme’s expense, mutually acceptable representatives of Genzyme to attend, as full and equal participants, material, substantive meetings, including pre-IND and end of Phase II Study meetings, with Regulatory Authorities in the Genzyme Territory pertaining to such Regional Licensed Product.

3.1.4. Submissions.

3.2. EMA Regulatory Strategy. Within [***] before the anticipated MAA filing for a Regional Licensed Product, the PJSC will determine an EMA regulatory strategy for such Regional Licensed Product pursuant to which the PJSC will determine (a) whether Alnylam will seek Regulatory Approval for such Regional Licensed Product in the EU using the EMA centralized or a national authorization procedure and (b) whether Genzyme will file a duplicate license with respect to any MAA held by Alnylam in the Alnylam Territory [***]. In determining the EMA regulatory strategy, the Parties agree to reasonably consider in good faith each Party’s interests. In the event that Genzyme files a duplicate license in the Genzyme Territory, Alnylam will coordinate communications with EMA, and provide support to enable Genzyme to efficiently obtain such duplicate license to provide for marketing in Genzyme countries under a separate, Genzyme trade name, to the extent not inconsistent with the Global Branding Strategy for such Regional Licensed Product.

3.3. Costs of Regulatory Affairs. Except as provided in Section 2.3 (Responsibilities for Development Activities and Costs) and Section 3.1.1.2, each Party shall be responsible for all costs and expenses incurred in connection with applying for, obtaining and maintaining Regulatory Approval with respect to Regional Licensed Products in its Territory, and related regulatory affairs activities.

10.2.2. Termination of a Regional Licensed Product for Cause. These Regional License Terms may be terminated with respect to any particular Regional Licensed Product at any time during the Term upon written notice by either Party if (a) the other Party is in material breach of its obligations hereunder with respect to such Regional Licensed Product and (b) the other Party has not cured such breach within thirty (30) days in the case of a payment breach, or within ninety (90) days in the case of all other breaches, after notice requesting cure of the breach; provided, however, that if any breach other than a payment breach is not reasonably curable within ninety (90) days and if a Party is making a bona fide effort to cure such breach, such termination shall be delayed for a time period to be agreed by both Parties, not to exceed an additional ninety (90) days, in order to permit such Party a reasonable period of time to cure such breach; and provided, further, that in the event that the breach relates to a dispute between the Parties regarding Genzyme’s obligations to use Commercially Reasonable Efforts in Developing or Commercializing such Regional Licensed Product and Genzyme disputes whether it has breached such obligation or whether such breach gives Alnylam the right to terminate these Regional License Terms with respect to such Regional Licensed Product and initiates a legal action against Alnylam to resolve such dispute within the foregoing sixty (60) day cure period, then these Regional License Terms shall not terminate during the pendency of such legal action, provided that if (i) Genzyme is found, in an unappealable decision by a court of competent

jurisdiction or an appealable decision of a court of competent jurisdiction that has not been appealed in the time allowed for an appeal in such legal action, to have materially breached these Regional License Terms with respect to such Regional Licensed Product, or (ii) Genzyme admits in such legal action or settlement thereof that it has materially breached these Regional License Terms with respect to such Regional Licensed Product, then these Regional License Terms shall terminate immediately with respect to such Regional Licensed Product following the Parties’ receipt of such decision or immediately following such admission, as applicable.

10.2.3. Termination of Regional Licensed Product upon Exercise of the Co-Co/Global Option in respect of a Regional Licensed Product. These Regional License Terms shall automatically be terminated with respect to a Regional Licensed Product if Genzyme exercises the Co-Co/Global Option in respect of such Regional Licensed Product under Section 3.2.2 of the Master Agreement (Co-Co/Global Option Grant), which termination shall be effective as of the Option Exercise Date for the Co-Co/Global Option. In such event such former Regional Licensed Product shall be a Co-Co Licensed Product or a Global Licensed Product, as applicable, and shall be governed by either the Co-Co License Terms or the Global License Terms.

10.2.4. Challenges of Patent Rights. If, during the Term, Genzyme or any of its Affiliates (a) commences or participates in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise asserts any claim, challenging or denying the validity or enforceability of any Alnylam Product-Specific Patent or any claim thereof or (b) actively assists any other Person or entity in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity or enforceability of any Alnylam Product-Specific Patent for a Regional Licensed Product or any claim thereof (each of (a) and (b), a “Patent Challenge”), then, to the extent permitted by the applicable Laws, Alnylam shall have the right, exercisable within sixty (60) days following receipt of notice regarding such Patent Challenge, in its sole discretion, to give notice to Genzyme that Alnylam may terminate these Regional Licensed Terms with respect to the Regional Licensed Product Covered by the Alnylam Product-Specific Patent that is the subject of the Patent Challenge (which termination will be effective ninety (90) days following such notice (or such longer period as Alnylam may designate in such notice)), and, unless Genzyme or such Affiliate withdraws or causes to be withdrawn all such challenge(s) (or in the case of ex-parte proceedings, multi-party proceedings, or other Patent Challenges that Genzyme or Genzyme’s Affiliates do not have the power to unilaterally withdraw or cause to be withdrawn, Genzyme and Genzyme’s Affiliates cease actively assisting any other party to such Patent Challenge and, to the extent Genzyme or a Genzyme Affiliate is a party to such Patent Challenge, it withdraws from such Patent Challenge) within such ninety (90)-day period, Alnylam will have the right to terminate these Regional License Terms with respect to such Regional Licensed Product by providing written notice thereof to Genzyme. The foregoing sentence shall not apply with respect to (i) any Alnylam Product-Specific Patent that Alnylam first asserts against Genzyme or any of its Affiliates where the Patent Challenge is made in defense of such assertion or (ii) any Patent Challenge commenced by a Third Party that, after the Effective Date, acquires or is acquired by Genzyme or its Affiliates or its or their business or assets, whether by stock purchase, merger, asset purchase or otherwise, but only with respect to Patent Challenges commenced prior to the closing of such acquisition.

10.2.5. Abandonment of Development. At any time on or after [***], either Party may terminate these Regional License Terms in their entirety (i.e., with respect to all Regional Licensed Products) if (a) no Regional Licensed Product has received Regulatory Approval anywhere in the Genzyme Territory, (b) no Regional Licensed Product is being Developed for the Genzyme Territory, (c) no Global Development Plan or Genzyme Territory Development Plan is in effect for any Regional Licensed Product, provided that, if Genzyme provides Alnylam with a good faith Genzyme Territory Development Plan pursuant to Section 2.2.4 (Genzyme Territory Development Plan) during the termination notice period set forth below in this Section 10.2.5, then the condition set forth in this clause (c) shall be deemed not satisfied at such time and the applicable termination notice shall be deemed not to have effect, and (d) the absence of Development in the Genzyme Territory or a good faith Genzyme Territory Development Plan is not the result of a breach by the Party seeking to terminate these Regional License Terms of its obligations under Section 2.4 (Diligence). In order to terminate these Regional License Terms pursuant to this Section 10.2.5, the terminating Party must provide at least six (6) months’ prior written notice to the other Party referencing this Section 10.2.5 and specifying a termination date [***], provided that, with respect to any such termination by Alnylam, such notice must also include an update regarding the current status of Alnylam’s Development activities with respect to Regional Licensed Products.

10.3.1.1. Effects of Termination of Regional Licensed Product by Genzyme for Cause. Without limiting any other legal or equitable remedies that either Party may have, if these Regional License Terms are terminated by Genzyme with respect to any particular Regional Licensed Product pursuant to Section 10.2.2 (Termination of a Regional Licensed Product for Cause), then:

(c) In the event that Genzyme elects not to seek or continue to seek or maintain patent protection on any Alnylam Product-Specific Patent in any country in the Licensed Territory, Genzyme shall notify Alnylam at least [***] days before such Alnylam Product-Specific Patent would become abandoned, no longer available or otherwise forfeit (including any decision by Genzyme not to continue to file and prosecute at least one patent application claiming priority to an Alnylam Product-Specific Patent issuing in any particular country). Alnylam shall have the right (but not the obligation), at its expense, to seek, prosecute and maintain in any country patent protection on any such Alnylam Product-Specific Patent (including the defense of any interference or opposition proceedings). If Alnylam exercises such right, the applicable Alnylam Product-Specific Patent (and all Patent Rights thereafter filed by or on behalf of Alnylam claiming priority thereto) shall no longer be treated as a “Alnylam Product-Specific Patent” hereunder, and if Controlled by Genzyme, Genzyme shall assign and transfer such Alnylam Product-Specific Patent to Alnylam. Genzyme shall make available to Alnylam its authorized attorneys, agents or representatives, such of its employees as are reasonably necessary to assist Alnylam in obtaining and maintaining the patent protection described under this Section 10.3.3(c). Genzyme shall sign, or have signed, all legal documents as are reasonably necessary to assist Alnylam in obtaining and maintaining the patent protection described under this Section 10.3.3(c).

[***] shall consult with [***] on the filing, prosecution and maintenance of all such Patent Rights. Each Party shall sign, or use Commercially Reasonable Efforts to have signed, all legal documents as are reasonably necessary to file and prosecute patent applications or to obtain or maintain patents in respect of such Joint Collaboration IP, at its own cost.

(b) [***] shall furnish to [***] via electronic mail or other such method as mutually agreed by the Parties copies of documents received from outside counsel in the course of such filing, prosecution or maintenance of Joint Collaboration IP and/or copies of documents relevant to such preparation, filing, prosecution, and maintenance in sufficient time prior to filing such document or making any payment due thereunder to allow for review and comment [***] and shall consider in good faith timely comments from [***] thereon. [***] shall furnish to [***] via electronic mail or other such method as mutually agreed by the Parties copies of such documents as filed in the relevant patent offices.

(c) In the event that [***] elects not to file or continue to prosecute or maintain patent protection on any Joint Collaboration IP, Alnylam shall have the right (but not the obligation) to file, prosecute and maintain Patent Rights comprising Joint Collaboration IP in the names of both Alnylam and Genzyme at [***] sole cost and expense. If [***] exercises such right, [***] shall make available to [***] its authorized attorneys, agents or representatives, and such of its employees as are reasonably necessary to assist [***] in obtaining and maintaining the patent protection described under this Section 10.3.4(c). [***] shall sign, or use Commercially Reasonable Efforts to have signed, all legal documents as are reasonably necessary to file and prosecute such patent applications or to obtain or maintain such patents.

(d) [***] shall bear all out-of-pocket patent filing, prosecution and maintenance expenses incurred with respect to Patent Rights comprising Joint Collaboration IP.

10.3.5 Patent Miscellaneous. Each Party hereby agrees: (a) to make its employees, agents and consultants reasonably available to the other Party (or to the other Party’s authorized attorneys, agents or representatives), to the extent reasonably necessary to enable such Party to undertake patent prosecution; (b) to provide the other Party with copies of all material correspondence pertaining to prosecution with the patent offices; (c) to cooperate, if necessary and appropriate, with the other Party in gaining patent term extensions wherever applicable to Patent Rights licensed under these Global License Terms; and (d) to endeavor in good faith to coordinate its efforts with the other Party to minimize or avoid interference with the prosecution and maintenance of the other Party’s patent applications.

10.3.6.1 Assignment of Alnylam Product-Specific Patents. On the Implementation Date with respect to a Global Licensed Product, Alnylam will assign and transfer to Genzyme, all rights, title, and interests in and to the Alnylam Product-Specific Patents with respect to such Global Licensed Product that are owned by Alnylam on the Implementation Date, and all claims and causes of action arising from or relating to such Alnylam Product-Specific Patents, including all rights to recovery for damages from infringement arising prior to, on or after the Implementation Date. On the Implementation Date for a Global Licensed Product, Alnylam will execute and deliver a confirmatory assignment relating to all Alnylam Product-Specific Patents with respect to such Global Licensed Product assigned to Genzyme under this Section 10.3.6.1 in a mutually agreed form.

10.3.6.2 Disclosure of Future Alnylam Product-Specific Patents. Upon becoming aware of any potentially patentable invention Controlled by Alnylam that would, if patented, be included within the definition of Alnylam Product-Specific Patents with respect to any Global Licensed Product, Alnylam will promptly disclose such invention to Genzyme in writing in reasonable detail via the IP Committee.

10.3.6.3 Covenants in Support of Assignment. Alnylam will provide all further cooperation which Genzyme reasonably determines is necessary to accomplish the complete transfer of the Alnylam Product-Specific Patents with respect to a Global Licensed Product, and all associated rights, to Genzyme on or after the Implementation Date for such Global Licensed Product, including executing and delivering further assignments, consents, releases and other commercially reasonable documentation, and providing good faith testimony by affidavit, declaration, deposition, in-person or other proper means and otherwise assisting Genzyme in support of any effort by Genzyme to establish, perfect, defend or enforce its rights in such Alnylam Product-Specific Patents through filing and prosecution of such Alnylam Product-Specific Patents, interferences, oppositions, other regulatory proceedings, litigation or other means. Alnylam will obtain the cooperation of the individual inventors of any inventions disclosed in such Alnylam Product-Specific Patents assigned to Genzyme pursuant to this Section 10.3.6, including (a) obtaining signatures of such inventors on any patent applications or other documentation reasonably necessary to obtain patent protection for such inventions and (b) procuring (at Genzyme’s expense) such inventors’ good faith testimony by affidavit, declaration, deposition in-person or other proper means in support of Genzyme’s efforts in establishing, perfecting, defending or enforcing patent rights to such inventions. To the extent Alnylam cannot transfer and assign the Alnylam Product-Specific Patents with respect to a Global Licensed Product, or any portion thereof, on the Implementation Date for such Global Licensed Product, then Alnylam will transfer and assign such Alnylam Product-Specific Patents to Genzyme at its first opportunity to do so

and, pending such transfer and assignment, such Alnylam Product-Specific Patents will be deemed to be Alnylam Patents for all purposes under these Global License Terms. To the extent further transfer or assignment of such Alnylam Product-Specific Patents is required or permitted, and Alnylam has not executed and returned to Genzyme the form of assignment reasonably requested by Genzyme within [***] business days of the delivery of such assignment to Alnylam at the address for notices set forth in Section 13.11 of the Master Agreement (Notices), then Alnylam hereby irrevocably appoints Genzyme as its attorney-in-fact with the right, authority and ability to execute and enter into such assignment on behalf of Alnylam. Alnylam stipulates and agrees that such appointment is a right coupled with an interest and will survive the unavailability of Alnylam at any future time.

10.3.6.4 Grant-Back License. Subject to the provisions of these Global License Terms, Genzyme hereby grants Alnylam a non-exclusive, non-transferable license (with no right to sublicense) under the Alnylam Product-Specific Patents to the extent necessary to perform Alnylam’s obligations under these Global License Terms and any GLP Supply Agreement.

10.4.1 Notices. Each Party shall promptly report in writing to the other Party any (a) known or suspected infringement of any Alnylam Technology, Genzyme Technology, Genzyme Manufacturing IP or Joint Collaboration IP or (b) unauthorized use or misappropriation of any Confidential Information or Know-How of a Party by a Third Party of which it becomes aware, in each case to the extent such infringing, unauthorized or misappropriating activities involve, as to a Global Licensed Product, a competing product in the Field (a “Competitive Infringement”), and shall provide the other Party with all available evidence of such infringement, unauthorized use or misappropriation.

(b) Alnylam Technology. Subject to the provisions of any In-License, Genzyme shall have the first right to initiate an Infringement Action anywhere in the world against any Third Party with respect to any Competitive Infringement in the Licensed Territory of any Alnylam Product-Specific Patent or Joint Collaboration IP, or, with Alnylam’s prior written consent, Alnylam Core Technology Patent or Alnylam

Know-How. Alnylam will consider in good faith any request from Genzyme to initiate an Infringement Action against any Third Party with respect to a Competitive Infringement in the Licensed Territory of any Alnylam Core Technology Patent; provided, however, that Alnylam shall not be required to initiate any such Infringement Action or permit Genzyme to initiate any such Infringement Action.

10.4.3 Procedures; Expenses and Recoveries. The Party having the right to initiate any Infringement Action under Section 10.4.2 (Rights to Enforce) above shall have the sole and exclusive right to select counsel for any such Infringement Action and shall pay all expenses of such Infringement Action, including attorneys’ fees and court costs and reimbursement of the other Party’s reasonable Global Out-of-Pocket Costs in rendering assistance requested by the initiating Party. If required under applicable Law in order for the initiating Party to initiate and/or maintain such Infringement Action, or if

either Party is unable to initiate or prosecute such Infringement Action solely in its own name or it is otherwise advisable to obtain an effective legal remedy, in each case, the other Party shall join as a party to such Infringement Action and will execute, and cause its Affiliates to execute, all documents necessary for the initiating Party to initiate litigation to prosecute and maintain such Infringement Action. In addition, at the initiating Party’s request, the other Party shall provide reasonable assistance to the initiating Party in connection with an Infringement Action at no charge to the initiating Party except for reimbursement by the initiating Party of reasonable Global Out-of-Pocket Costs incurred in rendering such assistance. The non-initiating Party shall have the right to participate and be represented in any such Infringement Action by its own counsel at its own expense. If the Parties obtain from a Third Party, in connection with such Infringement Action, any damages, license fees, royalties or other compensation (including any amount received in settlement of such litigation), after payment of any amounts required under any In-Licenses, the remaining amounts shall be allocated in all cases as follows:

Notwithstanding the foregoing, in the event that Alnylam elects to itself assert an Alnylam Core Technology Patent against a Competitive Infringement in the Licensed Territory, the Parties shall each be entitled to [***] of the balance of any recovery therefrom after reimbursement of expenses as described in clause (i) above.

10.5.1 Retained Alnylam Product-Specific Patent Rights. Subject to the provisions of any Alnylam In-License, Alnylam shall use Commercially Reasonable Efforts to obtain all available supplementary protection certificates (“SPCs”) and other extensions of Alnylam Product-Specific Patents in the Licensed Territory that are not assigned to Genzyme pursuant to Section 10.3.5. If more than one Alnylam Product-Specific Patent is eligible for extension or patent term restoration in the Licensed Territory, Genzyme will determine, in its sole discretion, a strategy that will be designed to maximize patent protection and commercial value for the Global Licensed Product, and the Parties, subject to the provisions of any In-License, will seek patent term extensions, restorations and SPCs for Alnylam Product-Specific Patents in the Licensed Territory in accordance with that strategy. Where required under national law, and subject to the other requirements of this Section 10.5, Alnylam will make the filings for such extensions, restorations and SPCs for Alnylam Product-Specific Patents in the Licensed Territory as directed by Genzyme.

10.5.2 Further Assurances for SPCs. Each Party will execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain any such extensions, restorations and SPCs for Alnylam Product-Specific Patents in the Licensed Territory, in accordance with this Section 10.5.

10.6 Common Interest. All information exchanged between the Parties’ representatives regarding the preparation, filing, prosecution, maintenance, or enforcement of the Patent Rights under this Section 10 will be deemed Confidential Information. In addition, the Parties acknowledge and agree that, with regard to such preparation, filing, prosecution, maintenance and enforcement of the Patent Rights under this Section 10, the interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in these Global License Terms constitutes a waiver of, any legal privilege concerning the Patent Rights under this Section 10, including privilege under the common interest doctrine and similar or related doctrines.

(a) Genzyme has the sole and exclusive right to select and develop one or more Product Trademark(s) for use by Genzyme and its Related Parties throughout the Licensed Territory. Such Product Trademark(s) may not include trademarks owned or Controlled by Alnylam (“Alnylam Trademarks”) and no right or license to any Alnylam Trademarks are conveyed hereunder to Genzyme. Any Product Trademark(s) that are used by Genzyme to promote and sell Licensed Products in the Licensed Territory are hereinafter referred to as the “Genzyme Trademarks.” Genzyme (or its Related Parties, as appropriate) shall own all rights to Genzyme Trademarks and all goodwill associated therewith, throughout the Licensed Territory. Genzyme shall also own rights to any Internet domain names incorporating the applicable Genzyme Trademarks or any variation or part of such Genzyme Trademarks used as its URL address or any part of such address.

(b) In the event that Alnylam becomes aware of any infringement of any Product Trademark by a Third Party, Alnylam shall promptly notify Genzyme and the Parties shall consult with each other and jointly determine the best way to prevent such infringement, including by the institution of legal proceedings against such Third Party.

10.8 Cooperative Research and Technology (CREATE) Act Acknowledgment. It is the intention of the Parties that these Global License Terms are a “joint research agreement” as that phrase is defined in Section 35 U.S.C. 103(c).

11.1 Term. These Global License Terms shall be effective as of the Implementation Date and, unless terminated earlier pursuant to Section 11.2 (Termination Rights), these Global License Terms shall continue in effect on a Global Licensed Product-by-Global Licensed Product and country-by-country basis until expiration of the last Royalty Term to expire under these Global License Terms (“Term”). Upon expiration of the Royalty Term for a Global Licensed Product, all licenses of the Parties under Section 7 (Licenses) with respect to such Global Licensed Product then in effect shall become fully paid-up, perpetual, exclusive licenses.

11.2 Termination Rights. These Global License Terms may be terminated by the Parties only as set forth in this Section 11.2.

11.2.1 Termination of Global Licensed Product for Convenience. Subject to the remainder of this Article 11, Genzyme shall have the right to terminate these Global License Terms with respect to any particular Global Licensed Product at any time after the Implementation Date on six (6) months prior written notice to Alnylam.

11.2.2 Termination of Global Licensed Product for Cause. These Global License Terms may be terminated with respect to any Global Licensed Product at any time during the Term upon written notice by either Party if (a) the other Party is in material breach of its obligations hereunder with respect to such Global Licensed Product, (b) such material breach relates to such Global Licensed Product and (c) the other Party has not cured such breach within thirty (30) days in the case of a payment breach, or within ninety (90) days in the case of all other breaches, after notice requesting cure of the breach; provided, however, that if any breach other than a payment breach is not reasonably curable within ninety (90) days and if a Party is making a bona fide effort to cure such breach, such termination shall be delayed for a time period to be agreed by both Parties, not to exceed an additional ninety (90) days, in order to permit such Party a reasonable period of time to cure such breach; provided, further, that in the event that the breach relates to a dispute between the Parties regarding Genzyme’s obligations to use Commercially Reasonable Efforts in Developing or Commercializing such Global Licensed Product and Genzyme disputes whether it has breached such obligation or whether such breach gives Alnylam the right to terminate these Global License Terms with respect to such Global Licensed Product and initiates a legal action against Alnylam to resolve such dispute within the foregoing sixty (60) day cure period, then these Global License Terms shall not terminate during the pendency of such legal action, provided that if (i) Genzyme is found, in an unappealable decision by a court of competent jurisdiction or an appealable decision of a court of competent jurisdiction that has not been appealed in the time allowed for an appeal in such legal action, to have materially breached these Global License Terms with respect to such Global Licensed Product, or (ii) Genzyme admits in such legal action or settlement thereof that it has materially breached these Global License Terms with respect to such Global Licensed Product, then these Global License Terms shall terminate immediately with respect to such Global Licensed Product following the Parties’ receipt of such decision or immediately following such admission, as applicable.

11.3.1 Effects of Termination of Global Licensed Product by Genzyme for Cause. Without limiting any other legal or equitable remedies that either Party may have, if these Global License Terms are terminated by Genzyme with respect to any Global Licensed Product pursuant to Section 11.2.2 (Termination of Global Licensed Product for Cause), then the provisions of this Section 11.3.1 shall apply:

(a) These Global License Terms shall terminate with respect to the rights and licenses granted to Genzyme for such terminated Global Licensed Product but shall continue to survive in all respects with respect to all Global Licensed Products other than the terminated Global Licensed Product.

(b) All License grants in these Global License Terms from either Party to the other with respect to the terminated Global Licensed Product shall immediately terminate.

(c) The Back-Up Option shall terminate with respect to all Back-Up Products for the terminated Global Licensed Product; provided, however, that such Back-Up Products shall, as of such date, be considered Option Products for the purposes of the Master Agreement, and the Options granted under the Master Agreement to siRNA that targets the same gene as the terminated Global Licensed Product shall again apply in accordance with the terms and conditions set forth in the Master Agreement;

(d) Genzyme shall as promptly as practicable transfer to Alnylam or Alnylam’s designee (i) possession and ownership of all Regulatory Approvals and pricing and reimbursement approvals relating to the Development, Manufacture or Commercialization of the terminated Global Licensed Product, and (ii) copies of all non-clinical and clinical data and material regulatory correspondence relating to the terminated Global Licensed Product, provided that Alnylam shall reimburse Genzyme for any reasonable out-of-pocket expenses incurred by Genzyme in connection with such transfer;

(e) Genzyme will assign and transfer to Alnylam, all rights, title and interests in and to any Alnylam Product Specific Patents that relate solely to the terminated Global Licensed Product that were assigned to Genzyme pursuant to Section 10.3.5 (Alnylam Product-Specific Patents), provided that Alnylam shall reimburse Genzyme for any reasonable out-of-pocket expenses incurred by Genzyme in connection with such assignment and transfer. In such event, Genzyme will execute and deliver a patent assignment relating to such Alnylam Product-Specific Patents in the form reasonably requested by Alnylam; and

(f) each Party shall promptly pay any amounts owed to the other Party as of the effective date of such termination.

11.3.2 Effects of Termination of Global Licensed Product by Alnylam for Cause or by Genzyme for Convenience. Without limiting any other legal or equitable remedies that either Party may have, if these Global License Terms are terminated with respect to any Global Licensed Product by Genzyme pursuant to Section 11.2.1 (Termination of Global Licensed Product for Convenience) or by Alnylam pursuant to Section 11.2.2 (Termination of Global Licensed Product for Cause), then the provisions of this Section 11.3.2 shall apply:

(b) The license grants to Alnylam in Section 7.2 (License Grants to Alnylam) shall survive such termination with respect to the Reverted Global Licensed Product.

(c) Genzyme will grant to Alnylam, effective upon the effective date of termination and subject to the terms of any applicable Genzyme In-License, a non-transferable, sublicensable (on terms consistent with Section 7.1.4 (Sublicensing Terms)), worldwide, non-exclusive, royalty-free license under any Genzyme Collaboration IP and Genzyme Patent Rights that Cover any Global Licensed Product that is being Developed or Commercialized by Genzyme pursuant to these Global License Terms on the effective date of termination, in the form that such Global Licensed Product exists on the effective date of termination (a “Reverted Global Licensed Product”), solely to the extent necessary to Develop and Commercialize the Reverted Global Licensed Product in the Field in the Licensed Territory. Notwithstanding the foregoing, if (i) any Patent Rights that Cover any Reverted Global Licensed Product are Controlled by Genzyme pursuant to a Genzyme In-License and (ii) such Genzyme In-License cannot be assigned to Alnylam or does not relate exclusively to the Reverted Global Licensed Product, Genzyme shall promptly disclose any payment obligations under such Genzyme In-License to Alnylam and such Genzyme Patent Rights shall be subject to the license granted in this Section 11.3.2(b) only if Alnylam agrees in writing to (A) reimburse Genzyme for one hundred percent (100%) of any amounts that become payable under such Genzyme In-License as a result of Alnylam’s exercise of the license granted in this Section 11.3.2(b), (B) comply with all applicable terms and conditions of such Genzyme In-License and (C) perform and take such actions as may be required to allow Genzyme to comply with its obligations under such Genzyme In-License.

(d) The Back-Up Option shall terminate with respect to all Back-Up Products for the terminated Global Licensed Product and such Back-Up Product shall be treated as an Option Product for which Genzyme has not exercised an Option for purposes of Section 3.5 of the Master Agreement;

(e) Genzyme will assign and transfer to Alnylam, all rights, title and interests in and to any Alnylam Product Specific Patents that relate solely to the terminated Global Licensed Product that were assigned to Genzyme pursuant to Section 10.3.5 (Alnylam Product-Specific Patents). In such event, Genzyme will execute and deliver a patent assignment relating to such Alnylam Product-Specific Patents in the form reasonably requested by Alnylam;

(f) Genzyme shall as promptly as practicable transfer to Alnylam or Alnylam’s designee (i) possession and ownership of all governmental or regulatory filings and approvals (including all Regulatory Approvals and pricing and reimbursement approvals) and material correspondence and conversation logs relating to the Development, Manufacture or Commercialization of the Reverted Global Licensed Product and all Genzyme Trademarks, (ii) copies of all data, reports, records and materials, and other sales and marketing related information in Genzyme’s possession or Control to the extent that such data, reports, records, materials or other information relate to the Development, Manufacture or Commercialization of the Reverted Global Licensed Product, including all non-clinical and clinical data relating to the Reverted Global Licensed Product, and customer lists and customer contact information and all adverse event data related to the Reverted Global Licensed Product in Genzyme’s possession or Control, provided that for a period of [***] months after the effective date of termination with respect to such Reverted Global Licensed Product, Genzyme shall use Commercially Reasonable Efforts to obtain for Alnylam the right to access all such data, reports, records, materials, and other sales and marketing related information), and (iii) all records and materials in Genzyme’s possession or Control containing Confidential Information of Alnylam exclusively related to the Reverted Global Licensed Product. In addition, Genzyme shall appoint Alnylam as Genzyme’s and/or Genzyme’s Related Parties’ agent for all Reverted Global Licensed Product-related matters involving Regulatory Authorities in the Licensed Territory until all Regulatory Approvals and other regulatory filings have been transferred to Alnylam or its designee.

(g) If the effective date of termination is after First Commercial Sale of the Reverted Global Licensed Product, then Genzyme shall appoint Alnylam as its exclusive distributor of the Reverted Global Licensed Product in the Licensed Territory and grant Alnylam the right to appoint sub-distributors, until such time as all Regulatory Approvals in the Licensed Territory have been transferred to Alnylam or its designee.

(h) If Genzyme or its Related Parties are Manufacturing finished product with respect to the Reverted Global Licensed Product on the effective date of termination, at Alnylam’s option, Genzyme or its Related Parties shall supply such finished product to

Alnylam in the Licensed Territory on terms no less favorable than those on which Genzyme supplied such finished product prior to such termination to its most favored distributor in the Licensed Territory, until the earlier of (i) such time as all Regulatory Approvals in the Licensed Territory related to the Reverted Global Licensed Product have been transferred to Alnylam or its designee, Alnylam has obtained all necessary manufacturing approvals and Alnylam has procured or developed its own source of such finished product supply or (ii) [***] months following the effective date of termination.

(i) If Alnylam so requests, and to the extent permitted under Genzyme’s obligations to Third Parties on the effective date of termination, Genzyme shall transfer to Alnylam any Third Party agreements relating solely and exclusively to the Development, Manufacture or Commercialization of the Reverted Global Licensed Product to which Genzyme is a party (including any Genzyme In-License), subject to any required consents of such Third Party, which Genzyme shall use Commercially Reasonable Efforts to obtain promptly.

(j) Genzyme shall promptly transfer and assign to Alnylam all of Genzyme’s and its Affiliates’ rights, title and interests in and to the Genzyme Trademark(s) exclusively used in connection with the Reverted Global Licensed Product (but not any Genzyme house marks or any trademark containing the word “Genzyme”) owned by Genzyme and used for the Reverted Global Licensed Product in the Field in the Licensed Territory.

(k) Genzyme shall transfer to Alnylam any inventory of the Reverted Global Licensed Product Controlled by Genzyme or its Affiliates as of the termination date at the actual price paid by Genzyme for such supply.

(l) Genzyme shall provide any other assistance reasonably requested by Alnylam for the purpose of allowing Alnylam or its designee to proceed expeditiously with the Development, Manufacture and Commercialization of the Reverted Global Licensed Product in the Licensed Territory; provided that Genzyme’s obligations under this clause shall expire [***] months after the effective date of termination of such Reverted Global Licensed Product.

(m) Genzyme shall execute all documents and take all such further actions as may be reasonably requested by Alnylam in order to give effect to the foregoing clauses.

11.4 Effect of Expiration or Termination; Survival. Any expiration or termination of these Global License Terms (a) shall not relieve the Parties of any obligation accruing prior to such expiration or termination and (b) shall be without prejudice to the rights of either Party against the other Party accrued or accruing under these Global License Terms prior to such expiration or termination, including the obligation to pay royalties for any Global Licensed Product sold prior to such expiration or termination. If these Global License Terms expire or are terminated with respect to any Global Licensed Product, the following provisions shall survive with respect to such

Global Licensed Product: (a) Sections 1 (Definitions), 9.3 (Warranty Disclaimer), 10.1 (Inventorship), 10.2 (Ownership), 11.3 (Effect of Termination), and 11.4 (Effect of Expiration or Termination; Survival), 12 (Performance of Affiliates) of these Global License Terms, and (b) Sections 1 (Definitions), 7 (Confidentiality and Publication), 9 (Royalty Reports; Payments; Audits), 10 (Indemnification; Limitation of Liability; Insurance), 12 (Term and Termination) and 13 (Miscellaneous) of the Master Agreement. Section 8.2.6 (Royalty Floor) shall survive any termination or expiration of these Global License Terms with respect to royalties accruing prior to such termination or expiration. Section 9 of the Master Agreement (Royalty Reports; Payments; Audit) shall survive for so long as any royalties are due under these Global License Terms plus three (3) years. Except as otherwise set forth in this Section 11, upon termination or expiration of these Global License Terms in their entirety (i.e., with respect to all Global Licensed Products), all rights and obligations of the Parties under these Global License Terms shall cease, but, for clarity, such expiration or termination of these Global License Terms shall not result in the termination or expiration of the Master Agreement or any License Terms. Upon termination or expiration of these Global License Terms with respect to any particular Global Licensed Product, all rights and obligations of the Parties under these Global License Terms with respect to such Global Licensed Product shall cease, but such termination or expiration shall not affect the Parties’ rights and obligations under these Global License Terms with respect to any other Global Licensed Product.

12.1 Use of Affiliates. Each Party acknowledges and accepts that the other Party may exercise its rights and perform its obligations under these Global License Terms either directly or through one or more of its Affiliates. A Party’s Affiliates will have the benefit of all rights (including all licenses) of such Party under these Global License Terms. Accordingly, in these Global License Terms “Genzyme” will be interpreted to mean “Genzyme and/or its Affiliates” and “Alnylam” will be interpreted to mean “Alnylam and/or its Affiliates” where necessary to give each Party’s Affiliates the benefit of the rights provided to such Party in these Global License Terms; provided, however, that in any event each Party will remain responsible for the acts and omissions, including financial liabilities, of its Affiliates.

12.3.3 For clarity, upon the closing of the acquisition of the stock and/or assets of Sirna Therapeutics, Inc. by Alnylam from Merck Sharpe & Dohme Corp., all relevant acquired intellectual property rights acquired in such transaction that may be Controlled by Alnylam (without any further action by Alnylam or Sirna Therapeutics, Inc.) shall become Controlled by Alnylam for the purposes of these Global License Terms.

2.1. Overview. The Parties will collaborate in the Development of each Co-Co Licensed Product pursuant to the applicable Global Development Plan and Genzyme Territory Development Plan. The PJSC will have primary responsibility for the oversight of the Global Development Plans, with Alnylam having primary responsibility for execution of those Global Development Plans, and Genzyme will have sole responsibility for the Genzyme Territory Development Plans, as described below.

2.2.1. Global Development Strategy. For each Co-Co Licensed Product, the key Development principles for such Co-Co Licensed Product will be set forth in a written summary of the global Development strategy for such Co-Co Licensed Product, including the indication(s) (including Secondary Indications), for which Regulatory Approval will be sought (each, a “Global Development Strategy”). The initial Global Development Strategy for ALN-TTRsc will be provided by Alnylam to Genzyme within [***] days after the Effective Date, agreed upon by the PJSC within [***] days after the Effective Date, and then attached hereto as Schedule 2.2.1-1. The initial Global Development Strategy for ALN-AT3 will be included in the Option Data Package, mutually agreed upon by the Parties prior to Genzyme’s exercise of the Co-Co/Global Option with respect to ALN-AT3 in accordance with the Master Agreement, and then attached hereto as Schedule 2.2.1-2. Any Global Development Strategy may be amended from time to time only by the PJSC responsible for the applicable Co-Co Licensed Product.

2.2.2.1. Global Development Plans. For each Co-Co Licensed Product, the Development activities that are necessary or useful to be undertaken for such Co-Co Licensed Product to achieve initial Regulatory Approval for each of the indications to be sought pursuant to the Global Development Strategy in at least all of the MMCs in a proximal fashion (including the design of necessary or useful Clinical Studies) will be set forth in reasonable detail in a written work plan and time table (each, a “Global Development Plan”). Alnylam will provide a draft of the initial Global Development Plan for ALN-TTRsc to Genzyme on or before March 31, 2014, and within [***] days thereafter the PJSC will review, update and approve such Global Development Plan and it will be attached hereto as Schedule 2.2.2-1. The initial Global Development Plan for ALN-AT3 will be prepared by Alnylam and included in the Option Data Package for ALN-AT3 provided by Alnylam to Genzyme under the Master Agreement, and if Genzyme exercises the Co-Co/Global Option for ALN-AT3, within [***] days of the Implementation Date for ALN-AT3 the PJSC responsible for ALN-AT3 will review, update and approve such Global Development Plan and it will be attached hereto as Schedule 2.2.2-2. Each Global Development Plan must, at all times, be consistent with the Global Development Strategy and include all Development activities that (i) are reasonably necessary to obtain initial Regulatory Approval of the applicable Co-Co Licensed Product in at least each MMC for each of the indications, including Secondary Indications, to be sought pursuant to the Global Development Strategy in a proximal fashion, (ii) Post-Marketing Studies for the Co-Co Territory and (iii) Secondary Indication Studies included in the initial Global Development Plan or added pursuant to Section 2.2.2.5 (Secondary Indications) (all such Development activities, collectively, the “Global Development Activities”); provided, however, that, unless otherwise agreed by the Parties, in no event will any Global Development Plan include (a) any Post-Marketing Study in the Genzyme Territory, (b) any Secondary Indication Study, except for Secondary Indication Studies included in the initial Global Development Plan or added to a Global Development Plan pursuant to Section 2.2.2.4 (Secondary Indications) or (c) after the last Regulatory Approval in all MMCs, any Development activity that is useful solely to achieve initial Regulatory Approval in a country in the Genzyme Territory that is not a Genzyme Territory MMC, except for Secondary Indication Studies included in the initial Global Development Plan or added to a Global Development Plan pursuant to Section 2.2.2.5 (Secondary Indications). In addition, for the period following the first Regulatory Approval in an MMC of a Co-Co Licensed Product, the Global Development Plan (and the Global Development Activities thereunder) must be established by the PJSC in a manner that reconciles the Parties’ preferences regarding short- and long-term profitability of such Co-Co Licensed Product. Each Global Development Plan will allocate responsibility for the performance of each Global Development Activity to one of the Parties. The time table for the

completion of the Global Development Activities included in each Global Development Plan will be designed to obtain initial Regulatory Approval of the applicable Co-Co Licensed Product in each MMC in a proximal fashion and as soon as reasonably possible. The terms of, and Development activities set forth in, each Global Development Plan will at all times be designed to be in compliance with all applicable Laws and in accordance with professional and ethical standards customary in the pharmaceutical industry.

2.2.2.2. Global Development Budgets. Each Global Development Plan will contain a [***] year rolling budget for the probable Global Regulatory Costs and probable Global Development Activities to be performed during the [***], and a forecast of the budgets for each subsequent Calendar Year thereafter through completion of all Global Development Activities set forth in any such Global Development Plan, provided that each initial Global Development Plan will also include such a budget for the partial Calendar Year commencing as of the date of such Global Development Plan and ending December 31 of such Calendar Year (each such [***] budget plus any such partial Calendar Year is a “Global Development Budget”). Each Global Development Budget will be updated annually by the PJSC responsible for the applicable Co-Co Licensed Product in accordance with Section 2.2.2.3 (Managing and Amending Global Development Plans and Global Development Budgets). The initial Global Development Budget for a Co-Co Licensed Product, and each update thereto, will be prepared by the PJSC in accordance with [***]:

submissions to, each Regulatory Authority in the Co-Co Territory with respect to such Co-Co Licensed Product; (ii) interfacing, corresponding and meeting with each Regulatory Authority in the Co-Co Territory with respect to such Co-Co Licensed Product; and (iii) seeking and maintaining all regulatory filings in the Co-Co Territory with respect to such Co-Co Licensed Product; provided, however, that Alnylam and Genzyme may have roles of varying responsibility for such activities in respect of the Co-Co Licensed Products in the Co-Co Territory as is set forth in the applicable Global Development Plan.

3.2.3. Communications with Regulatory Authorities. Alnylam will notify the Genzyme representatives on the PJSC responsible for a Co-Co Licensed Product in writing, including a brief description in English, of the principal issues raised in any material communication with any Regulatory Authority in the Co-Co Territory with respect to such Co-Co Licensed Product within [***] days after receipt of such material communication. Alnylam will allow Genzyme a reasonable opportunity to review and comment on Alnylam’s proposed response to any such material communications in advance of the transmission of any such response, and Alnylam will reasonably consider all comments timely provided by Genzyme in connection therewith. Upon Genzyme’s reasonable request after receiving a notice from Alnylam in accordance with the immediately preceding sentence, Alnylam will provide to Genzyme: (i) at Alnylam’s expense, a summary translation of the applicable material communication in English; (ii) at Alnylam’s expense, complete copies of the original correspondence with the applicable Regulatory Authority in their native language; or (iii) at Genzyme’s expense, a full translation of the applicable material communication in English, in each case (i) through (iii) within a reasonable period of time following such request. For purposes of this Section 3.2.3, “material communication” will include any meetings with Regulatory Authorities, or questions or concerns from Regulatory Authorities, regarding significant issues, such as key product quality attributes (e.g., purity), safety findings affecting the platform (e.g., Serious Adverse Events, emerging safety signals), clinical or nonclinical findings affecting patient safety, lack of efficacy, or receipt or denial of Regulatory Approval.

3.2.4. Meetings with Regulatory Authorities. Alnylam shall provide Genzyme with reasonable advance notice of all substantive meetings with Regulatory Authorities in the Co-Co Territory pertaining to each Co-Co Licensed Product, or with as much advance notice as practicable under the circumstances. Alnylam shall use Commercially Reasonable Efforts, to the extent reasonably practicable, to permit Genzyme to have, at Genzyme’s expense, mutually acceptable representatives of Genzyme attend the following: (i) solely as non-participating observers, material, substantive meetings (including pre-IND and end of Phase II Study meetings) with Regulatory Authorities in the Co-Co Territory pertaining to such Co-Co Licensed Product, and (ii) any internal Alnylam meetings held in preparation for such material, substantive meetings with Regulatory Authorities in the Co-Co Territory.

3.2.5. Submissions. With respect to each Co-Co Licensed Product, Alnylam will allow Genzyme a reasonable opportunity to review and comment on all regulatory filings and other submissions to Regulatory Authorities or other Governmental Authorities in the Co-Co Territory in advance of the submission of any such filing, and Alnylam will reasonably consider

all comments timely provided by Genzyme in connection therewith. In addition, Alnylam shall provide Genzyme with prompt written notice of each of the following events (but in any event within [***] days) after the occurrence of such event in the Co-Co Territory: (i) the filing of any IND for such Co-Co Licensed Product; (ii) the submission of any filings or applications for Regulatory Approval (including orphan drug applications and designations) of such Co-Co Licensed Product to any Regulatory Authority; and (iii) receipt or denial of Regulatory Approval for such Co-Co Licensed Product; provided, however, that in all circumstances, Alnylam shall inform Genzyme of such event prior to public disclosure of such event by Alnylam.

3.3. EMA Regulatory Strategy. Within [***] year before the anticipated MAA filing for a Co-Co Licensed Product, the PJSC will determine an EMA regulatory strategy for such Co-Co Licensed Product pursuant to which the PJSC will determine (a) whether Alnylam will seek Regulatory Approval for such Co-Co Licensed Product in the EU using the EMA centralized or a national authorization procedure and (b) whether Genzyme will file a duplicate license with respect to any MAA held by Alnylam in the Co-Co Territory [***]. In determining the EMA regulatory strategy, the Parties agree to reasonably consider in good faith each Party’s interests. In the event that Genzyme files a duplicate license in the Genzyme Territory, Alnylam will coordinate communications with EMA, and provide support to enable Genzyme to efficiently obtain such duplicate license to provide for marketing in Genzyme countries under a separate, Genzyme trade name, to the extent not inconsistent with the Global Commercial Strategy or Global Branding Strategy for such Co-Co Licensed Product.

3.4. Costs of Regulatory Affairs. Except as provided in Sections 2.3 (Joint Responsibilities for Development Activities and Costs) and 3.1.1.2 (Ownership of Regulatory Filings), each Party shall be responsible for all costs and expenses incurred in connection with applying for, obtaining and maintaining Regulatory Approval with respect to Co-Co Licensed Products, and related regulatory affairs activities.

3.5. Right of Reference. Each Party hereby grants to the other Party, and at the request of the other Party will grant to the other Party’s Related Parties, a “Right of Reference,” as that term is defined in 21 C.F.R. § 314.3(b) (or any successor rule or analogous Law recognized outside of the United States), to, and a right to copy, access, and otherwise use, all information and data (including all CMC information as well as data made, collected or otherwise generated in the conduct of any Clinical Studies or Secondary Indication Studies or early access/named patient programs for the Co-Co Licensed Products) included in or used in support of any regulatory filing, Regulatory Approval, drug master file or other regulatory documentation (including orphan drug applications and designations) owned or controlled by such Party or its Related Parties that relates to (a) any Co-Co Licensed Product or (b) with respect to such information and data provided to Genzyme, the siRNA Controlled by Alnylam and known as ALN-TTR01, to the extent necessary or useful to obtain Regulatory Approval of a Co-Co Licensed Product in the Genzyme Territory, and such Party shall provide a signed statement to this effect, if requested by the other Party, in accordance with 21 C.F.R. § 314.50(g)(3) (or any successor or analogous Law outside of the United States). In addition, upon request of either Party (on behalf of itself or a Sublicensee), the other Party shall obtain and

provide to the requesting Party certificates or other formal or official attestations concerning the regulatory status of the Co-Co Licensed Products in the Genzyme Territory or the Co-Co Territory, as applicable (e.g., Certificates of Free Sale, Certificates for Export, Certificates to Foreign Governments). Notwithstanding anything to the contrary in these Co-Co License Terms, neither Party shall withdraw or inactivate any regulatory filing that the other Party references or otherwise uses pursuant to this Section 3.5.

4.1.1. Global Commercial Strategy. For each Co-Co Licensed Product, the key Commercialization principles will be set forth in a written summary of the global Commercialization strategy for such Co-Co Licensed Product (each, a “Global Commercial Strategy”). Alnylam shall provide the initial draft of such Global Commercial Strategy to the PJSC responsible for the applicable Co-Co Licensed Product within [***] days after the Implementation Date for such Co-Co Licensed Product, and within [***] days after provision, such PJSC shall review, update and approve such Global Commercial Strategy. The PJSC for such Co-Co Licensed Product will update and amend the Global Commercial Strategy not later than the initiation of the first Phase III Study for such Co-Co Licensed Product, and then annually thereafter.

Each Co-Co Territory Commercialization Plan must, at all times, include a detailed description of the S&M Activities

to be undertaken in each country in the Co-Co Territory with respect to the applicable Co-Co Licensed Product during the then-current Calendar Year and the next Calendar Year. Each Co-Co Territory Commercialization Plan shall be consistent with the requirements of the applicable Global Commercialization Strategy, as such Global Commercialization Strategy may be updated as reasonably necessary. Any amendment to a Global Commercialization Strategy shall take into account the then-current deployment of resources and time required to realign resources consistent with the Global Commercialization Strategy in a reasonable manner, and with this Section 4.2.1. The Commercialization Activities set forth in each Co-Co Territory Commercialization Plan will at all times be designed to be in compliance with all applicable Laws and in accordance with professional and ethical standards customary in the pharmaceutical industry.

4.2.1.1. ALN-TTRsc Co-Co Territory Commercialization Plan. Within [***] year after the Effective Date, Alnylam will provide a draft of the initial Co-Co Territory Commercialization Plan for ALN-TTRsc to the PJSC, and within [***] days thereafter, the PJSC will review, update and approve such Co-Co Territory Commercialization Plan and it will be attached hereto as Schedule 4.2-1.

4.2.1.2. ALN-AT3 Co-Co Territory Commercialization Plan. The initial Co-Co Territory Commercialization Plan for ALN-AT3 will be prepared and approved by the PJSC no later than [***] years prior to the anticipated date of the First Commercial Sale of ALN-AT3 in any country in the Co-Co Territory and, upon approval, it will be attached hereto as Schedule 4.2-2.

4.2.1.3. Allocation of S&M Activities. Promptly following the approval of any Co-Co Territory Commercialization Plan in accordance with this Section 4.2.1 or Section 4.2.4, the Parties shall allocate responsibility for each S&M Activity to be performed in the next Calendar Year between the Parties in an equitable manner mutually agreed by the Parties, which allocation shall be made on an activity-by-activity or S&M FTE-by-S&M FTE basis, as applicable, and subject to the following:

(a) each Party will have the right to provide up to [***] in each country in the Co-Co Territory in such Calendar Year; and

4.2.2. Diligence. If the PJSC agrees upon the allocation of responsibility for the S&M Activities in a Co-Co Territory Commercialization Plan [***].

4.2.3. Co-Co Territory Commercialization Budget. Each Co-Co Territory Commercialization Plan will contain a budget for the S&M Activities (and no other activities) to be performed during the then-current Calendar Year with respect to the applicable Co-Co Licensed Product in the Co-Co Territory (a “Co-Co Territory Commercialization Budget”), which budget will allocate expenditures equitably across the countries in the Co-Co Territory,

taking into account the allocation of activities described in Section 4.2.1.3 (Allocation of S&M Activities) and the then-current and future commercial opportunities for such Co-Co Licensed Product. Each Co-Co Territory Commercialization Budget will be updated annually by the PJSC responsible for the applicable Co-Co Licensed Product in accordance with Section 4.2.4 (Managing and Amending Co-Co Territory Commercialization Plans and Co-Co Territory Commercialization Budgets). The initial Co-Co Territory Commercialization Budget for a Co-Co Licensed Product, and each update thereto, will be prepared by the PJSC [***]. Alnylam will enter such Co-Co Commercialization Budget in a template that the Parties agree is efficient for both Parties to communicate such information. [***]

4.2.4. Managing and Amending Co-Co Territory Commercialization Plans and Co-Co Territory Commercialization Budgets. For each Co-Co Licensed Product, Alnylam will update and amend, and the PJSC will approve, the applicable Co-Co Territory Commercialization Plan from time-to-time as it deems necessary and, until such time as no further S&M Activities are occurring or expected to occur with respect to such Co-Co Licensed Product, the Co-Co Territory Commercialization Plan will be updated as follows:

(a) No later than [***] of each Calendar Year, Alnylam shall prepare, and the applicable PJSC will approve, an updated draft of the Co-Co Territory Commercialization Plan, which shall contain a proposed Co-Co Territory Commercialization Budget covering the next Calendar Year. The proposed Co-Co Territory Commercialization Budget will satisfy the requirements set forth in Section 4.2.3 (Co-Co Territory Commercialization Budget).

(b) No later than [***] of each Calendar Year, Alnylam shall prepare, and the applicable PJSC will review and tentatively approve an updated Co-Co Territory Commercialization Plan and Co-Co Territory Commercialization Budget for such Co-Co Licensed Product, and such updated Co-Co Territory Commercialization Plan and Co-Co Territory Commercialization Budget will become effective upon such tentative approval by the PJSC, provided that the Parties acknowledge and agree that each Party’s internal process for receiving final approval of such Co-Co Territory Commercialization Plan and Co-Co Territory Commercialization Budget from its Board of Directors may occur after [***] (but, in any event, before [***]) and Co-Co Territory Commercialization Plan and Co-Co Territory Commercialization Budget will not become final unless and until such approvals are obtained. In no event may any Co-Co Territory Commercialization Plan be amended with the result that it fails to satisfy the requirements for Co-Co Territory Commercialization Plans set forth in Section 4.2.1 (Co-Co Territory Commercialization Plan).

4.2.5. Responsibility for Co-Co Territory Commercialization Costs. With respect to each Co-Co Licensed Product, unless otherwise agreed to by the Parties in writing [***]. On the first day of each Calendar Year, the PJSC responsible for a Co-Co Licensed Product will determine the total S&M Costs allocated to each Party for such Calendar Year under the applicable Co-Co Territory Commercialization Budget, which S&M Costs shall be calculated by [***].

4.2.6. Verification. With respect to each Co-Co Licensed Product, promptly following the end of each Calendar Year, the Head of the Rare Disease Business of Genzyme and an appropriate officer of Alnylam shall certify to one another in writing whether or not such Party has spent the S&M Costs allocated to such Party in the applicable Co-Co Territory Commercialization Budget during such Calendar Year in performing the S&M Activities allocated to such Party in the applicable Co-Co Territory Commercialization Plan. If either Party did not spend all of the S&M Costs or perform all of the S&M Activities allocated to such Party in the applicable Co-Co Territory Commercialization Plan, then such Party shall pay the other Party an amount equal to [***] of the difference between the S&M Costs and S&M Activities allocated to such Party in the applicable Co-Co Territory Commercialization Plan and the S&M Costs and S&M Activities certified as being spent or performed by such Party. The certification mechanism and true-up payment provided for in this Section 4.2.6 shall be in lieu of auditing the Parties’ S&M Costs and S&M Activities for Co-Co Licensed Products in the Co-Co Territory.

4.3. Genzyme Territory Commercialization Plan. No less than [***] months in advance of the reasonably expected first Regulatory Approval in the Genzyme Territory with respect to a Co-Co Licensed Product, and on an annual basis thereafter, Genzyme shall prepare and deliver to the PJSC responsible for such Co-Co Licensed Product for review a reasonable written plan that summarizes the Commercialization activities to be undertaken with respect to such Co-Co Licensed Product in the Genzyme Territory in the next Calendar Year and, to the extent commercially reasonable, Genzyme’s plans to obtain further Regulatory Approvals and Commercialize such Co-Co Licensed Product in countries in the Genzyme Territory in which Genzyme is not then Commercializing such Co-Co Licensed Product, and the dates by which such activities are targeted to be accomplished (the “Genzyme Territory Commercialization Plan”). Each Genzyme Territory Commercialization Plan shall be consistent with the requirements of the initial Global Commercialization Strategy approved by the PJSC pursuant to Section 4.1.1 (Global Commercial Strategy) or the most recently approved by the PJSC without the use of tie-break authority pursuant to Section 5.7.3 (Tie-Breaking). The Genzyme Territory Commercialization Plan for a Co-Co Licensed Product shall subsequently be updated and modified by Genzyme, from time to time at its discretion and no less frequently than once per Calendar Year, based upon, among other things, Genzyme’s Commercialization activities with respect to such Co-Co Licensed Product in the Genzyme Territory, a copy of which updated plan Genzyme will provide to the PJSC responsible for such Co-Co Licensed Product. [***].

4.4.1. Global Branding. Alnylam shall have the right, from time to time during the Term, to develop (and thereafter to modify and update) a global branding strategy (including global positioning, colors and other visual branding elements) for each Co-Co Licensed Product for use in the Field throughout the world (the “Global Branding Strategy”), which the PJSC responsible for such Co-Co Licensed Product shall, in accordance with Sections 5.6 (PJSC

Commercialization Responsibilities) and 5.7 (PJSC Decision-Making), review and approve, and which the Parties shall, following such review and approval, implement. Alnylam will submit the Global Branding Strategy for a Co-Co Licensed Product to the PJSC responsible for such Co-Co Licensed Product at least annually (or more frequently if reasonably requested by Genzyme). Alnylam shall consider in good faith any timely comments Genzyme may have with respect to any Global Branding Strategy, but shall have final decision-making authority with respect to such Global Branding Strategy. Notwithstanding the foregoing, Alnylam shall ensure that the Global Branding Strategy complies with applicable Laws in the Genzyme Territory, and that any branding elements selected for inclusion in the Global Branding Strategy do not infringe any Third Party trademarks or other intellectual property rights.

Each Party shall provide such other information to the PJSC responsible for a Co-Co Licensed Product as the other Party may reasonably request with respect to Commercialization of such Co-Co Licensed Product and shall keep such PJSC reasonably informed of such Party’s Commercialization activities in the Co-Co Territory with respect to such Co-Co Licensed Product.

4.5. Commercialization Reporting Obligations. Each Party and its Related Parties shall be responsible for booking sales in its Territory (for avoidance of doubt, meaning, with respect to the Co-Co Territory, Alnylam, and with respect to the Genzyme Territory, Genzyme). Each Party and its Related Parties may warehouse Co-Co Licensed Products both inside and outside of such Party’s Territory, provided that any sales with respect to such Co-Co Licensed Products are booked in such Party’s Territory. If a Party receives any orders for any Co-Co Licensed Product in the other Party’s Territory, it shall refer such orders to the other Party, to the extent it is not prohibited from doing so under applicable Law. Moreover, each Party and its Related Parties shall be solely responsible for handling all returns of any Co-Co Licensed Product sold in its Territory, as well as all aspects of Co-Co Licensed Product order processing, invoicing and collection, distribution, inventory and receivables of Co-Co Licensed Products sold in its Territory.

4.6. Recalls, Market Withdrawals or Corrective Actions. In the event that any Regulatory Authority issues or requests a recall or takes a similar action in connection with a Co-Co Licensed Product in the Co-Co Territory or Genzyme Territory, or in the event either Party determines that an event, incident or circumstance has occurred that may result in the need for a recall or market withdrawal of a Co-Co Licensed Product in the Co-Co Territory or Genzyme determines that an event, incident or circumstance has occurred that may result in the need for a recall or market withdrawal of a Co-Co Licensed Product in the Genzyme Territory, the Party notified of such recall or similar action, or the Party that desires such recall or similar action, shall within [***] hours notify the other Party’s CLP Alliance Manager and PJSC representatives thereof by telephone or e-mail. The Parties shall mutually agree whether to conduct a recall of a Co-Co Licensed Product in the Co-Co Territory and the manner in which any such recall shall be conducted (except in the case of a government mandated recall, when the Party subject to such mandate may act without such advance notice but shall notify the other Party as soon as possible). Genzyme shall determine whether to conduct a recall of a Co-Co Licensed Product in the Genzyme Territory and the manner in which any such recall shall be conducted (except in the case of a government mandated recall, when Genzyme may act without such advance notice but shall notify Alnylam as soon as possible). Except as may be otherwise agreed by the Parties, each Party shall share equally the expense of any such recall in the Co-Co Territory and Genzyme shall bear the expense of any such recall in the Genzyme Territory. Each Party will make available all of its pertinent records that may be reasonably requested by the other Party in order to effect a recall of a Co-Co Licensed Product in the Co-Co Territory or Genzyme Territory. The Parties’ rights and obligations under this Section 4.6 shall be subject to the terms of any supply agreement(s) entered into between the Parties and, in the event of any conflict between the provisions of any such supply agreement and this Section 4.6, the provisions of such supply agreement shall govern.

5.1.1. Composition of the Product Joint Steering Committee. The Development and Commercialization of each Co-Co Licensed Product pursuant to the Co-Co Collaboration will be conducted under the oversight of a PJSC, which shall be comprised of three (3) representatives of each Party. The PJSC for ALN-TTRsc shall be established as of the

Effective Date. Each Party shall appoint its respective representatives to each PJSC from time to time following the Implementation Date for ALN-AT3, and may substitute one or more of its representatives on any PJSC, in its sole discretion, effective upon notice to the other Party of such change. Each Party shall have at least one representative on each PJSC who is a senior employee (vice president level or above), and all representatives on each PJSC shall have appropriate expertise, seniority, decision-making authority and ongoing familiarity with the Co-Co Collaboration and the applicable Co-Co Licensed Product. Unless otherwise agreed by the Parties, each Party’s representatives on any PJSC must be employees of such Party or any of its Affiliates. For the avoidance of doubt, the same representatives from each Party may serve on the PJSC for more than one Co-Co Licensed Product. Additional representatives or consultants may from time to time, by mutual consent of the Parties, be invited to attend PJSC meetings, subject to such representatives and consultants undertaking confidentiality obligations, whether in a written agreement or by operation of law, no less stringent than the requirements of Section 7 of the Master Agreement (Confidentiality and Publication).

5.2. Appointment of Subcommittees, Project Teams and CLP Alliance Managers. Each PJSC shall be empowered to create such subcommittees and project teams as it may deem appropriate or necessary, such as for specific oversight of Development, Manufacturing, Commercialization or intellectual property issues relating to the Co-Co Licensed Product for which such PJSC is responsible. Each such project team created by a PJSC shall report to such PJSC, which shall have authority to approve or reject recommendations or actions proposed by such project team, subject to these Co-Co License Terms. For the avoidance of doubt, the same representatives from each Party may serve on the project team for more than one Co-Co Licensed Product. Each Party will designate an alliance manager for each Co-Co Licensed Product (each, a “CLP Alliance Manager”) to serve as a primary point of contact for the other Party with respect to all activities under the CLP Collaboration related to such Co-Co Licensed Product. Each CLP Alliance Manager’s responsibilities shall include (a) scheduling meetings of the PJSC at least once per Calendar Quarter, but more frequently if the PJSC determines it necessary; (b) setting agendas for PJSC meetings with solicited input from the CLP Alliance Manager for the other Party and other members of the PJSC; and (c) coordinating the delivery of draft minutes to the PJSC for review and final approval. Beginning with Alnylam’s CLP Alliance Manager, such responsibilities shall alternate between the CLP Alliance Managers from each Party on a meeting-by-meeting basis after each meeting of the applicable committee. Each Party may change any of its CLP Alliance Managers at any time in its sole discretion with written notice to the other Party, provided that each CLP Alliance Manager will be individually identified at all times and will have such experience, authority, responsibility and accountability as is reasonably sufficient to enable such person to fulfill his or her responsibilities as a CLP Alliance Manager under these Co-Co License Terms on behalf of the applicable Party.

5.3. PJSC Meetings. Each PJSC shall meet in accordance with a schedule established by mutual written agreement of the Parties, but no less frequently than once per Calendar Quarter during the Term, with the location for such meetings alternating between Alnylam and Genzyme facilities (or such other locations as are mutually agreed by the Parties). Alternatively, a PJSC may meet by means of teleconference, videoconference or other similar communications equipment, but at least two (2) meetings of such PJSC per Calendar Year shall be conducted in person. All proceedings for each PJSC shall take place in English. Where the membership of a PJSC for a Co-Co Licensed Product is the same as one or more other PJSCs for the other Co-Co Licensed Product, such PJSCs may have a single meeting to discuss each Co-Co Licensed Product for which they have responsibility. Each Party shall bear its own expenses relating to attendance at such meetings by its representatives.

5.4. PJSC Minutes. A CLP Alliance Manager shall be appointed secretary for each meeting of each PJSC and shall prepare minutes of the meeting, which shall provide a description in reasonable detail of the discussions held at the meeting and a list of any actions, decisions or determinations approved by such PJSC. Within [***] days after each meeting, the drafting CLP Alliance Manager shall provide the draft minutes to the other CLP Alliance Manager for review and comment. The drafting CLP Alliance Manager shall reasonably consider all comments from the other CLP Alliance Manager within [***] days. The drafting CLP Alliance Manager shall prepare and submit revised minutes for approval within [***] days after receipt of such comments or upon expiration of such [***] day period.

The Party having the right to initiate any Infringement Action under Section 11.4.2 (Rights to Enforce) above shall have the sole and exclusive right to select counsel for any such Infringement Action and shall pay all expenses of the suit, including attorneys’ fees and court costs and reimbursement of the other Party’s reasonable Co-Co Out-of-Pocket Costs in rendering assistance requested by the initiating Party. If required under applicable Law in order for the initiating Party to initiate and/or maintain such Infringement Action, or if either Party is unable to initiate or prosecute such Infringement Action solely in its own name or it is otherwise advisable to obtain an effective legal remedy, in each case, the other Party shall join as a party to the Infringement Action and will execute and cause its Affiliates to execute all documents necessary for the initiating Party to initiate litigation to prosecute and maintain such action. In addition, at the initiating Party’s request, the other Party shall provide reasonable assistance to the initiating Party in connection with an Infringement Action at no charge to the initiating Party except for reimbursement by the initiating Party of reasonable Co-Co Out-of-Pocket Costs incurred in rendering such assistance. The non-initiating Party shall have the right to participate and be represented in any such Infringement Action by its own counsel at its own expense. If the Parties obtain from a Third Party, in connection with such Infringement Action, any damages, license fees, royalties or other compensation (including any amount received in settlement of such litigation), after payment of any amounts required under any In-Licenses, the remaining amounts shall be allocated in all cases as follows:

(a) first, to reimburse each Party for all expenses of the Infringement Action incurred by the Parties, including attorneys’ fees and disbursements, court costs and other litigation expenses;

(b) second, [***] of the balance to be paid to the Party initiating the Infringement Action, with respect to Infringement Actions in the Genzyme Territory, and [***] of the balance to be paid to the Party initiating the Infringement Action, with respect to Infringement Actions in the Co-Co Territory; and

Notwithstanding the foregoing, in the event that Alnylam elects to itself assert an Alnylam Core Technology Patent against a Competitive Infringement in the Genzyme Territory, the Parties shall each be entitled to [***] of the balance of any recovery therefrom after reimbursement of expenses as described in clause (i) above. In addition, with respect to Infringement Actions brought in the Co-Co Territory, the Parties shall share evenly the expenses of the suit, including attorneys’ fees of each Party, court costs, and both Parties’ reasonable Co-Co Out-of-Pocket expenses in rendering assistance related to the Infringement Action (“Litigation Expenses”). For such Infringement Actions brought in the Co-Co Territory, Litigation Expenses shall initially be borne by the Party incurring the expense. Each Party will calculate and maintain records of Litigation Expenses incurred by it and its Affiliates with respect to any such Infringement Action, and, within thirty (30) days following the end of each Calendar Quarter, each Party shall submit to the other a report detailing the Litigation Expenses incurred by it and its Affiliates during such Calendar Quarter. Unless otherwise agreed by the Parties, the Party that incurs more than its share of the total Litigation Expenses with respect to such an Infringement Action in the Co-Co Territory during any Calendar Quarter shall be paid by the other Party an amount of cash sufficient to reconcile to its fifty percent (50%) share of Litigation Expenses.

11.5.1. Retained Alnylam Product-Specific Patent Rights. Subject to the provisions of any Alnylam In-License, Alnylam shall use Commercially Reasonable Efforts to obtain all available supplementary protection certificates (“SPCs”) and other extensions of Alnylam Product-Specific Patents in the Genzyme Territory[***]. If more than one Alnylam Product-Specific Patent is eligible for extension or patent term restoration in the Genzyme Territory, Genzyme will determine, in its sole discretion, a strategy that will be designed to maximize patent protection and commercial value for the Co-Co Licensed Product, and the Parties, subject to the provisions of any In-License, will seek patent term extensions, restorations and SPCs for Alnylam Product-Specific Patents in the Genzyme Territory in accordance with that strategy. Where required under national law, and subject to the other requirements of this Section 11.5, Alnylam will make the filings for such extensions, restorations and SPCs for Alnylam Product-Specific Patents in the Genzyme Territory as directed by Genzyme.

11.5.2. Further Assurances for SPCs. Each Party will execute such authorizations and other documents and take such other actions as may be reasonably requested by the other Party to obtain any such extensions, restorations and SPCs for Alnylam Product-Specific Patents in the Genzyme Territory, in accordance with this Section 11.5.

11.6. Common Interest. All information exchanged between the Parties’ representatives regarding the preparation, filing, prosecution, maintenance, or enforcement of the Patent Rights under this Section 11 will be deemed Confidential Information. In addition, the Parties acknowledge and agree that, with regard to such preparation, filing, prosecution, maintenance, and enforcement of the Patents Rights under this Section 11, the interests of the Parties as collaborators and licensor and licensee are to obtain the strongest patent protection possible, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in these Co-Co License Terms constitutes a waiver of, any legal privilege concerning the Patents Rights under this Section 11, including privilege under the common interest doctrine and similar or related doctrines.

(a) Each Party has the right to use any trademark it owns or controls for Co-Co Licensed Products in its Territory at its sole discretion, and each Party and its Affiliates shall retain all right, title and interest in and to its and their respective corporate names and logos.

In order to terminate these Co-Co License Terms pursuant to this Section 12.2.4, the terminating Party must provide at least six (6) months’ prior written notice to the other Party referencing this Section 12.2.4 and specifying a termination date on or after [***], provided that, with respect to any such termination by Alnylam, such notice must also include an update regarding the current status of Alnylam’s Development activities with respect to Co-Co Licensed Products.

12.3.1. Effects of Termination by Genzyme for Cause. Without limiting any other legal or equitable remedies that either Party may have, if these Co-Co License Terms are terminated by Genzyme with respect to any particular Co-Co Licensed Product pursuant to Section 12.2.2 (Termination for Cause), then:

(a) these Co-Co License Terms shall continue to survive in all respects with respect to all Co-Co Licensed Products other than the terminated Co-Co Licensed Product;

(b) all license grants in these Co-Co License Terms with respect to the terminated Co-Co Licensed Product from either Party to the other shall immediately terminate;

(c) the Back-Up Option shall terminate with respect to all Back-Up Products for the terminated Co-Co Licensed Product; provided, however, that such Back-Up Products shall, as of such date, be considered Option Products for the purposes of the Master Agreement, and the Options granted under the Master Agreement to siRNA that targets the same gene as the terminated Co-Co Licensed Product shall again apply in accordance with the terms and conditions set forth in the Master Agreement;

(d) Genzyme shall as promptly as practicable transfer to Alnylam or Alnylam’s designee (i) possession and ownership of all Regulatory Approvals and pricing and reimbursement approvals relating to the Development, Manufacture or Commercialization of the terminated Co-Co Licensed Product, and (ii) copies of all non-clinical and clinical data and material regulatory correspondence relating to the terminated Co-Co Licensed Product, provided that Alnylam shall reimburse Genzyme for any reasonable out-of-pocket expenses incurred by Genzyme in connection with such transfer;

(e) Genzyme will assign and transfer to Alnylam all rights, title and interests in and to any Alnylam Product-Specific Patents that relate solely to the terminated Co-Co Licensed Product that were assigned to Genzyme pursuant to Section 11.3.6 (Assignment of Alnylam Product-Specific Patents to Genzyme), provided that Alnylam shall reimburse Genzyme for any reasonable out-of-pocket expenses incurred by Genzyme in connection with such assignment and transfer. In such event, Genzyme will execute and deliver a patent assignment relating to such Alnylam Product-Specific Patents in the same form used to assign such Patent Rights to Genzyme; and

(f) each Party shall promptly pay any amounts owed to the other Party as of the effective date of such termination.

12.3.2. Effects of Termination by Alnylam for Cause or by Genzyme for Convenience. Without limiting any other legal or equitable remedies that either Party may have, if these Co-Co License Terms are terminated with respect to any particular Co-Co Licensed Product by Genzyme pursuant to Section 12.2.1 (Termination for Convenience) or by Alnylam under Section 12.2.2 (Termination for Cause) or Section 12.2.3 (Challenges of Patent Rights), then:

(a) these Co-Co License Terms shall continue to survive in all respects with respect to all Co-Co Licensed Products other than the terminated Co-Co Licensed Product;

(b) all licenses granted by Alnylam to Genzyme in these Co-Co License Terms with respect to the terminated Co-Co Licensed Product shall immediately terminate;

(c) the Back-Up Option shall terminate with respect to all Back-Up Products for the terminated Co-Co Licensed Product and such Back-Up Products shall be treated as Option Products for which Genzyme has not exercised an Option for purposes of Section 3.5 of the Master Agreement;

(d) Genzyme will assign and transfer to Alnylam, all rights, title and interests in and to any Alnylam Product Specific Patents that relate solely to the terminated Co-Co Licensed Product that were assigned to Genzyme pursuant to Section 11.3.6 (Assignment of Alnylam Product-Specific Patents to Genzyme). In such event, Genzyme will execute and deliver a patent assignment relating to such Alnylam Product-Specific Patents in the same form used to assign such Patent Rights to Genzyme;

(e) Genzyme will grant to Alnylam, effective upon the effective date of termination and subject to the provisions of any applicable Genzyme In-License, a non-transferable, sublicensable (on terms consistent with Section 7.2.4 (Sublicensing Terms)), worldwide, non-exclusive, royalty-free license under any Genzyme Collaboration IP and Genzyme Patent Rights that Cover the terminated Co-Co Licensed Product, in the form that such terminated Co-Co Licensed Product exists on the effective date of termination (the “Reverted Co-Co Licensed Product”), solely to the extent necessary to Develop and Commercialize the Reverted Co-Co Licensed Product in the Field in the Genzyme Territory. Notwithstanding the foregoing, if (i) any Patent Rights that Cover the Reverted Co-Co Licensed Product are Controlled by Genzyme pursuant to a Genzyme In-License and (ii) such Genzyme In-License cannot be assigned to Alnylam or does not relate exclusively to the Reverted Co-Co Licensed Product, Genzyme shall promptly disclose any payment obligations under such Genzyme In-License to Alnylam and such Genzyme Patent Rights shall be subject to the license granted in this Section 12.3.2(e) only if Alnylam agrees in writing to (A) reimburse Genzyme for one hundred percent (100%) of any amounts that become payable under such Genzyme In-License as a result of Alnylam’s exercise of the license granted in this Section 12.3.2(e), (B) comply with all applicable terms and conditions of such Genzyme In-License and (C) perform and take such actions as may be required to allow Genzyme to comply with its obligations under such Genzyme In-License.

(f) The license grants to Alnylam in Section 7.2 (License Grants to Alnylam) shall survive and shall be expanded to include the Genzyme Territory with respect to the Reverted Co-Co Licensed Product.

months after the effective date of termination with respect to such Reverted Co-Co Licensed Product, Genzyme shall use Commercially Reasonable Efforts to obtain for Alnylam the right to access all such data, reports, records, materials, and other sales and marketing related information related to the Reverted Co-Co Licensed Product, and (iii) all records and materials in Genzyme’s possession or Control containing Confidential Information of Alnylam solely relating to the Reverted Co-Co Licensed Product. In addition, Genzyme shall appoint Alnylam as Genzyme’s and/or Genzyme’s Related Parties’ agent for all matters related to the Reverted Co-Co Licensed Product involving Regulatory Authorities in the Genzyme Territory until all Regulatory Approvals and other regulatory filings have been transferred to Alnylam or its designee.

(h) If the effective date of termination is after First Commercial Sale of the Reverted Co-Co Licensed Product, then Genzyme shall appoint Alnylam as its exclusive distributor of the Reverted Co-Co Licensed Product in the Genzyme Territory and grant Alnylam the right to appoint sub-distributors, until such time as all Regulatory Approvals in the Genzyme Territory have been transferred to Alnylam or its designee.

(i) If Genzyme or its Related Parties are Manufacturing finished product with respect to the Reverted Co-Co Licensed Product on the effective date of termination, at Alnylam’s option, Genzyme or its Related Parties shall supply such finished product to Alnylam in the Genzyme Territory on terms no less favorable than those on which Genzyme supplied such finished product prior to such termination to its most favored distributor in the Genzyme Territory, until the earlier of (i) such time as all Regulatory Approvals in the Genzyme Territory solely related to the Reverted Co-Co Licensed Product have been transferred to Alnylam or its designee, Alnylam has obtained all necessary manufacturing approvals and Alnylam has procured or developed its own source of such finished product supply or (ii) [***] months following the effective date of such termination.

(j) If Alnylam so requests, and to the extent permitted under Genzyme’s obligations to Third Parties on the effective date of termination, Genzyme shall transfer to Alnylam any Third Party agreements relating solely and exclusively to the Development, Manufacture or Commercialization of the Reverted Co-Co Licensed Product to which Genzyme is a party (including any Genzyme In-License), subject to any required consents of such Third Party, which Genzyme shall use Commercially Reasonable Efforts to obtain promptly.

(k) Genzyme shall promptly transfer and assign to Alnylam all of Genzyme’s and its Affiliates’ rights, title and interests in and to the Genzyme Trademark(s) (but not any Genzyme house marks or any trademark containing the word “Genzyme” owned by Genzyme and used for the Reverted Co-Co Licensed Product in the Field in the Genzyme Territory) owned by Genzyme and used solely and exclusively for the Reverted Co-Co Licensed Product in the Field in the Genzyme Territory.

(l) Genzyme shall transfer to Alnylam any inventory of the Reverted Co-Co Licensed Products Controlled by Genzyme or its Affiliates as of the termination date at the actual price paid by Genzyme for such supply.

(m) Genzyme shall provide any other assistance reasonably requested by Alnylam for the purpose of allowing Alnylam or its designee to proceed expeditiously with the Development, Manufacture and Commercialization of the Reverted Co-Co Licensed Product in the Genzyme Territory, provided that Genzyme’s obligations under this clause (m) of Section 12.3.2 shall expire [***] months after the effective date of termination of such Reverted Co-Co Licensed Product.

(n) Genzyme shall execute all documents and take all such further actions as may be reasonably requested by Alnylam in order to give effect to the foregoing clauses.

12.3.3. Effects of Termination for Abandonment of Development. If these Co-Co License Terms are terminated in their entirety (i.e., with respect to all Co-Co Licensed Products) by either Party pursuant to Section 12.2.4 (Abandonment of Development), then the license granted to Alnylam under Section 7.2.2 (License to Improvement Manufacturing Patent Rights) shall survive and all other licenses granted in these Co-Co License Terms from either Party to the other shall immediately terminate and:

(a) the Back-Up Option shall terminate with respect to all Back-Up Products for the terminated Co-Co Licensed Products ;

(b) Genzyme shall as promptly as practicable transfer to Alnylam or Alnylam’s designee (i) possession and ownership of all Regulatory Approvals and pricing and reimbursement approvals relating to the Development, Manufacture or Commercialization of the terminated Co-Co Licensed Product, and (ii) copies of all non-clinical and clinical data and material regulatory correspondence relating to the terminated Co-Co Licensed Product;

(c) Genzyme will assign and transfer to Alnylam, all rights, title and interests in and to any Alnylam Product Specific Patents that relate solely to the terminated Co-Co Licensed Product that were assigned to Genzyme pursuant to Section 11.3.6 (Assignment of Alnylam Product-Specific Patents to Genzyme). In such event, Genzyme will execute and deliver a patent assignment relating to such Alnylam Product-Specific Patents in the same form used to assign such Patent Rights to Genzyme; and

(d) each Party shall promptly pay any amounts owed to the other Party as of the effective date of such termination.

12.4. Fundamental Breach of Alnylam’s Development Obligations. Without limiting Genzyme’s rights under Section 12.2.2 (Termination for Cause) with respect to other material breaches, in the event that Alnylam commits a Fundamental Breach of its Development obligations under Section 2.4.2 (Alnylam Diligence) with respect to any particular Co-Co Licensed Product, and Genzyme does not terminate these Co-Co License Terms in their entirety (i.e., with respect to all Co-Co Licensed Products) or with respect to such Co-Co Licensed Product for cause pursuant to Section 12.2.2 (Termination for Cause), then Genzyme may elect to receive the following remedies for such Fundamental Breach:

12.4.1. Genzyme’s obligation to pay development milestone fees under Section 8.1 (Development Milestone Fees) with respect to such Co-Co Licensed Product shall automatically terminate;

12.4.2. Genzyme will receive a credit, which Genzyme may offset against royalties and other amounts payable under these Co-Co License Terms due to Alnylam with respect to such Co-Co Licensed Product pursuant to Section 8 (Financial Terms for Genzyme Territory), in an amount equal to one hundred fifty percent (150%) of all costs and expenses (i) incurred by Genzyme to Develop such Co-Co Licensed Product for the Genzyme Territory that are in excess of the costs budgeted by Genzyme in connection with the Genzyme Territory Development Plan for such Co-Co Licensed Product in effect at the time of Alnylam’s Fundamental Breach of Section 2.4.2 (Alnylam Diligence) with respect to such Co-Co Licensed Product and (ii) are incurred by Genzyme as a direct consequence of Alnylam’s Fundamental Breach of Section 2.4.2 (Alnylam Diligence) with respect to such Co-Co Licensed Product;

12.4.3. Genzyme may, in its discretion, terminate any or all of the following provisions of these Co-Co License Terms (or any subsection thereof) with respect to such Co-Co Licensed Product: Section 3.1.4 (Meetings with Regulatory Authorities), Section 4.1.2 (Co-Co Territory), Section 4.2.1 (Co-Co Territory Commercialization Plan), Section 4.3 (Genzyme Territory Commercialization Plan), Section 4.4 (Advertising and Promotional Materials), Section 4.5 (Commercialization Reporting Obligations) and Section 5 (Collaboration Management); and

12.4.4. Without limiting Genzyme’s remedies under these Co-Co License Terms or otherwise with respect to breaches of Alnylam’s Development obligations under clause (a) of Section 2.4.2 (Alnylam Diligence) other than Fundamental Breaches, if Genzyme elects to receive the remedies set forth in this Section 12.4 with respect to a Fundamental Breach of its Development obligations under clause (a) of Section 2.4.2 (Alnylam Diligence) with respect to any Co-Co Licensed Product, such remedies shall be Genzyme’s sole and exclusive remedies with respect to such Fundamental Breach and Genzyme shall have no right to seek any further remedies or damages against Alnylam and its Affiliates with respect to such Fundamental Breach by Alnylam of clause (a) of Section 2.4.2 (Alnylam Diligence).

12.5. Effect of Expiration or Termination; Survival. Any expiration or termination of these Co-Co License Terms (a) shall not relieve the Parties of any obligation accruing prior to such expiration or termination and (b) shall be without prejudice to the rights of either Party against the other accrued or accruing under these Co-Co License Terms prior to expiration or termination, including the obligation to pay royalties for any Co-Co Licensed Product sold prior to such expiration or termination. The following provisions shall survive any expiration or

termination of these Co-Co License Terms in their entirety (i.e., with respect to all Co-Co Licensed Products) and, if these Co-Co License Terms expire or are terminated with respect to any particular Co-Co Licensed Product, shall survive with respect to such Co-Co Licensed Product: (a) Sections 1 (Definitions), 9 (Financial Terms for Co-Co Territory), 10.3 (Warranty Disclaimer), 11.1 (Inventorship), 11.2 (Ownership), 12.3 (Effect of Termination), 12.5 (Effect of Termination or Expiration; Survival), Section 13 (Performance by Affiliates) of these Co-Co License Terms and (b) Sections 1 (Definitions), 7 (Confidentiality and Publication), 10 (Indemnification; Limitation of Liability; Insurance), 12 (Term and Termination) and 13 (Miscellaneous) of the Master Agreement. Section 8.2.6 (Royalty Floor) shall survive any termination or expiration of these Co-Co License Terms with respect to any Co-Co Licensed Product for royalties accruing prior to such termination or expiration. Section 9 of the Master Agreement (Royalty Reports; Payments; Audit) will survive for so long as any royalties are due under these Co-Co License Terms plus three (3) years. Except as otherwise set forth in this Section 12 or elsewhere in these Co-Co License Terms, upon termination or expiration of these Co-Co License Terms in their entirety, all rights and obligations of the Parties under these Co-Co License Terms shall cease, but, for clarity, expiration or termination of these Co-Co License Terms in their entirety (i.e., with respect to all Co-Co Licensed Products) shall not result in the termination or expiration of the Master Agreement or any other License Terms. Upon termination or expiration of these Co-Co License Terms with respect to any particular Co-Co Licensed Product, all rights and obligations of the Parties under these Co-Co License Terms with respect to such Co-Co Licensed Product shall cease except as otherwise set forth in this Section 12 or elsewhere in these Co-Co License Terms, but, for clarity, such termination or expiration shall not affect the Parties’ rights and obligations under these Co-Co License Terms with respect to the other Co-Co Licensed Product.

13.1. Use of Affiliates. Each Party acknowledges and accepts that the other Party may exercise its rights and perform its obligations under these Co-Co License Terms either directly or through one or more of its Affiliates. A Party’s Affiliates will have the benefit of all rights (including all licenses) of such Party under these Co-Co License Terms. Accordingly, in these Co-Co License Terms “Genzyme” will be interpreted to mean “Genzyme and/or its Affiliates” and “Alnylam” will be interpreted to mean “Alnylam and/or its Affiliates” where necessary to give each Party’s Affiliates the benefit of the rights provided to such Party in these Co-Co License Terms; provided, however, that in any event each Party will remain responsible for the acts and omissions, including financial liabilities, of its Affiliates.

13.3.3. For clarity, upon the closing of the acquisition of the stock and/or assets of Sirna Therapeutics, Inc. by Alnylam from Merck Sharpe & Dohme Corp., all relevant acquired intellectual property rights acquired in such transaction that may be Controlled by Alnylam (without any further action by Alnylam or Sirna Therapeutics, Inc.) shall become Controlled by Alnylam for the purposes of these Co-Co License Terms.
