Upon expiration of the Royalty Term for the Licensed Products, all licenses of the Parties under Section 7 (Licenses) with respect to the Licensed Products then in effect shall become fully paid-up, perpetual licenses. This Agreement shall terminate automatically in the event that either Party exercises its right to terminate Amendment No. 2 pursuant to Section 2.4 thereof.

13.2Termination Rights. This Agreement may be terminated by the Parties only as set forth in Amendment No. 2 or this Section 13.2.

13.2.1Termination of Licensed Products for Convenience. Subject to the remainder of this Section 13, Alnylam shall have the right to terminate this Agreement with respect to any or all Licensed Products at any time after the Effective Date on six (6) months prior written notice to Genzyme.

13.2.2Termination of Licensed Products for Cause. This Agreement may be terminated, on a Licensed Product-by-Licensed Product basis, with respect to any 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 Licensed Product, (b) such material breach relates to such Licensed Product and (c) the other Party has not cured such breach within [***] days in the case of a payment breach, or within [***] 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 [***] 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 [***] 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 Alnylam’s obligations to use Commercially Reasonable Efforts in Developing or Commercializing such Licensed Product and Alnylam disputes whether it has breached such obligation or whether such breach gives Genzyme the right to terminate this Agreement with respect to such Licensed Product and initiates a legal action against Genzyme to resolve such dispute within the foregoing [***] day cure period, then this Agreement shall not terminate during the pendency of such legal action, provided that if (i) Alnylam 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 this Agreement with respect to such Licensed Product, or (ii)

Alnylam admits in such legal action or settlement thereof that it has materially breached this Agreement with respect to such Licensed Product, then, upon written notice by Genzyme, this Agreement shall terminate immediately with respect to such Licensed Product following the Parties’ receipt of such decision or immediately following such admission, as applicable.

13.2.3Challenges of Patent Rights. If, during the Term, Alnylam 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 claim within the Genzyme Patent Rights or (b) actively assists any other Person 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 claim of such Patent Rights (each of (a) and (b), a “Patent Challenge”), then, to the extent permitted by the applicable Laws, Genzyme shall have the right, exercisable within [***] days following receipt of notice regarding such Patent Challenge, in its sole discretion, to give notice to Alnylam that Genzyme may terminate this Agreement [***] days following such notice (or such longer period as Genzyme may designate in such notice), and, unless Alnylam 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 Alnylam or Alnylam’s Affiliates do not have the power to unilaterally withdraw or cause to be withdrawn, Alnylam and Alnylam’s Affiliates cease actively assisting any other party to such Patent Challenge and, to the extent Alnylam or an Alnylam Affiliate is a party to such Patent Challenge, it withdraws from such Patent Challenge) within such [***]-day period, Genzyme shall have the right to terminate this Agreement by providing written notice thereof to Alnylam. The foregoing sentence shall not apply with respect to any Patent Challenge commenced by a Third Party that after the Effective Date acquires or is acquired by Alnylam 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.

13.3Effect of Termination; Alternative Remedy.

13.3.1Effects of Termination of Licensed Products by Alnylam for Cause; Alternative Remedy.

13.3.1.1Without limiting any other legal or equitable remedies that either Party may have, if this Agreement is terminated by Alnylam with respect to any Licensed Products pursuant to Section 13.2.2 (Termination of Licensed Products for Cause), then the provisions of this Section 13.3.1.1 shall apply:

(a)This Agreement shall terminate with respect to the rights and licenses granted to Alnylam for such terminated Licensed Products but shall continue to survive in all respects with respect to all Licensed Products other than the terminated Licensed Products.

13.3.1.2If Alnylam has the right to terminate this Agreement with respect to any or all Licensed Products pursuant to Section 13.2.2 (Termination of Licensed Products for Cause), then Alnylam may, by written notice to Genzyme, opt not to terminate the Agreement pursuant to Section 13.2.2 (Termination of Licensed Products for Cause) but instead to continue the Agreement in full force and effect; provided that, as of the expiration of the cure period applicable to such material breach by Genzyme and for the remainder of the applicable Royalty Term hereunder, the royalty rates payable by Alnylam on Net Sales of such Licensed Products as under determined under Section 8.1 (Royalties) shall be reduced by [***] percent ([***]%).

13.3.2Effects of Termination of Licensed Products by Genzyme for Cause or by Alnylam for Convenience. Without limiting any other legal or equitable remedies that either Party may have, if this Agreement is terminated with respect to any Licensed Products by Alnylam pursuant to Section 13.2.1 (Termination of Licensed Products for Convenience) or by Genzyme pursuant to Section 13.2.2 (Termination of Licensed Products for Cause), then the provisions of this Section 13.3.2 shall apply:

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

(c)Alnylam and its Related Parties shall cease all Development and Commercialization of the Licensed Products throughout the Territory.

13.4Effect of Expiration or Termination; Survival. Any expiration or termination of this Agreement (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 this Agreement prior to such expiration or termination, including the obligation to pay royalties for any Licensed

Products sold prior to such expiration or termination. If this Agreement expires or is terminated with respect to any Licensed Products, the following provisions shall survive with respect to such Licensed Products: Sections 1 (Definitions), 8 (Certain Financial Terms), 9.1 (Nondisclosure Obligations), 10.2 (Warranty Disclaimer), 11 (Indemnification; Limitation of Liability; Insurance), 12.1 (Inventorship), 12.2 (Ownership), 13.1 (Term), 13.3 (Effect of Termination; Alternative Remedy), and 13.4 (Effect of Expiration or Termination; Survival) and 15 (Miscellaneous). Section 8.3.4 (Royalty Floor) shall survive any termination or expiration of this Agreement with respect to royalties accruing prior to such termination or expiration. Section 8 (Certain Financial Terms) shall survive for so long as any royalties are due under this Agreement plus three (3) years. Except as otherwise set forth in this Section 13, upon termination or expiration of this Agreement in its entirety (i.e., with respect to all Licensed Products), all rights and obligations of the Parties under this Agreement shall cease.
