ALN-AT3 Global License Terms

after the Implementation Date, the Parties shall prepare and deliver to the JTT a draft plan for the transition of the Development and Commercialization of the Global AT3 Licensed Product from Alnylam to Genzyme (a “Transition Plan”), a high-level outline of which is attached hereto as Exhibit A. Promptly following the delivery of such draft Transition Plan to the JTT (and in any event no later than [***] days following such delivery), the JTT shall finalize the Transition Plan and such Transition Plan shall be incorporated into this Agreement by reference and shall replace Exhibit A hereto. The Transition Plan for each Global AT3 Licensed Product will require Alnylam to, as soon as reasonably practicable following the Implementation Date with respect to such Global AT3 Licensed Product: (a) [***]. The Transition Plan for each Global AT3 Licensed Product will also describe any Development and Commercialization (including with respect to medical affairs activities) activities with respect to such Global AT3 Licensed Product that Alnylam is required to perform as requested by Genzyme and mutually agreed upon by the Parties (“Execution Activities” and together with the Transfer Activities, the “Transition Activities”) as further described in Section 2.2.3 (Support of Global Development and Commercialization) below. [***]. With respect to Alnylam employees having experience or expertise relevant to the Development or Commercialization of the Global AT3 Licensed Products as conducted prior to the Effective Date, Alnylam shall (i) commit a sufficient portion of such employee’s working hours to enable the completion of the activities set forth in the Transition Plan for the Global AT3 Licensed Products in accordance with the timeline set forth in such Transition Plan and (ii) make such employees available to Genzyme at Genzyme’s reasonable request until the obligations in such Transition Plan with respect to which such employee has responsibilities are completed.

2.2.2Amendments and Extension to Term of Transition Plan. The Parties anticipate that, with respect to ALN-AT3, the Transition Plan will cover a [***]-month period from the Execution Date, acknowledging that no Transfer Activities may be initiated prior to the Effective Date. If, during the Transition Period, the Execution Activities performed by or on behalf of Alnylam under the Transition Plan exceed Fifty Million Dollars ($50,000,000), then Alnylam may propose an amendment to the Transition Plan to account for such additional Execution Activities and/or such additional costs, and if agreed by the JTT, the Transition Plan shall be amended to include such additional Execution Activities and/or costs at Genzyme’s expense. In the event that Genzyme does not agree to such amendment to the Transition Plan, then Genzyme shall have no obligation to pay any additional amounts in respect of the Execution Activities, and Alnylam shall have no obligation to perform any additional Execution Activities or to incur costs covered under the proposed amendment. Furthermore, in the event that Alnylam cannot deliver the Certification described in Section 2.2.4 (Certification; Term of Transition Plan) below within the aforementioned [***]-month period, then Alnylam shall have the right to request an extension to the Transition Plan in accordance with Section 2.2.4 (Certification; Term of Transition Plan).

ALN-AT3 Global License Terms

2.2.3Support of Global Development and Commercialization. [***]. Unless otherwise agreed by the Parties, the Execution Activities for ALN-AT3 will include the obligations under the Existing Global Development Plan and the Co-Co Territory Commercialization Plan approved by the Parties for use in connection with ALN-AT3 under the Collaboration Agreement as such plans were in effect immediately prior to the Effective Date, for the portion of such plans as are within the Transition Period.

2.2.4Certification; Term of Transition Plan. Alnylam shall notify Genzyme when Alnylam can certify, in good faith and to the best of its Knowledge, that, as of the date of such certification, (a) [***], (b) the Transfer Activities described in Sections 2.2.1(a), (c), (d) and (e) have been completed, (c) the Transfer Activities described in Sections 2.2.1(b) and (f) have been substantially completed, (d) the Execution Activities to be performed by Alnylam have been substantially completed and (e) that, with respect to any Transition Activity that has not been completed in full of which Alnylam has Knowledge (the “Uncompleted Transition Activities”), (i) the identity of any such Uncompleted Transition Activity has been included as an attachment to such certification and (ii) such failure to have completed such Transition Activity in full either (Y) arose out of circumstances that are beyond the reasonable control of Alnylam despite the use of Diligent Efforts by Alnylam (including for example, a failure of Genzyme to use diligence efforts in connection with the Transition Activities) or (Z) would not reasonably be expected to have a material adverse effect on the Development or Commercialization of the Global AT3 Licensed Product in the Licensed Territory (the “Certification”). If Alnylam does not provide such Certification on or before the date that is [***] months after the Execution Date (the “Initial Transition Deadline”) or identifies any Uncompleted Transition Activities in its Certification as of the Initial Transition Deadline, then Alnylam shall have the right to request an extension to the Initial Transition Deadline, and the JTT shall amend the Transition Plan and shall make any changes or adjustments reasonably necessary to address specific root causes of delay and to expedite completion of the Transition Activities by no later than the date that is [***] months from the Initial Transition Deadline (such date, the “Final Transition Deadline”).

10.4.2Rights to Enforce.

ALN-AT3 Global License Terms

(a)

Genzyme Technology. Subject to the provisions of any In-License, Genzyme shall have the sole and exclusive right to initiate an infringement or other appropriate suit (an “Infringement Action”) anywhere in the world against any Third Party as to any infringement, or suspected infringement of, any Patent Rights, or as to any use or suspected use without proper authorization of any Know-How, comprising Genzyme Patent Rights, Genzyme Know-How, Genzyme Collaboration IP or Genzyme Manufacturing IP.

(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.

(c)

Step-In Right.

(i)

If, within [***] days (or such shorter period of time as required by applicable Law to avoid loss of material enforcement rights) after Genzyme’s receipt of a notice of a Competitive Infringement with respect to any Alnylam Product-Specific Patent or Joint Collaboration IP, Genzyme does not initiate any Infringement Action permitted hereunder against such Competitive Infringement in the Licensed Territory, Alnylam may elect, in its sole discretion, to bring and control an Infringement Action in connection therewith at its sole cost and expense by providing written notice of such election to Genzyme.

ALN-AT3 Global License Terms

(ii)

If (A) there are no Alnylam Product-Specific Patents or Patent Rights included in Joint Collaboration IP that can be asserted against a Competitive Infringement in the Licensed Territory, for any reason other than the unwillingness of Genzyme to consent to such assertion of any Patent Rights included in the Joint Collaboration IP; (B) there are Alnylam Core Technology Patent(s) that can reasonably be asserted, but Alnylam refuses to either permit Genzyme to assert or itself assert at least one of such Alnylam Core Technology Patent(s) that can reasonably be asserted against a Competitive Infringement in the Licensed Territory; and (C) Genzyme and Alnylam are unable to stop the Competitive Infringement through enforcement of any other Patent Rights or Know-How Controlled by either Party, then the royalties to be paid by Genzyme to Alnylam pursuant to Section 8.2 (Royalties), with respect to the applicable Global AT3 Licensed Product in the countries in the Licensed Territory where such Competitive Infringement exists, shall be reduced by [***] during the period when the conditions in the foregoing clauses (A), (B) and (C) exist and such Competitive Infringement continues, subject to the limitations set forth in Section 8.2 (Royalties).

10.4.3Procedures; 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

ALN-AT3 Global License Terms

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:

(i)

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

(ii)

second, [***] percent ([***]%) of the balance to be paid to the Party initiating such Infringement Action; and

(iii)

third, the remainder to the other Party.

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 [***] percent ([***]%) of the balance of any recovery therefrom after reimbursement of expenses as described in clause (i) above.
