14.3 Article 14.2 shall not prevent a party hereto from applying to a court of competent jurisdiction for interim protection such

Execution Copy



16.0 TERM:

16.1 This Agreement and the license granted hereunder shall terminate on the expiration of a term of 20 years from the Date of Commencement or the expiration of the last Patent, whichever event shall last
occur, unless earlier terminated as a result of the termination of Alnylams rights to INEX Technology (as that term is defined in the LCA) under the LCA. Upon expiry of the term of this Agreement (but not on earlier termination of this
Agreement for any other reason) Alnylam shall thereafter have, in perpetuity, a fully paid-up world wide license to use and sublicense the Technology and to manufacture, have made, distribute, import, use and sell Products in the Alnylam Field,
without further payment of Royalties to Inex. The parties acknowledge that, (a) upon termination of the LCA under certain circumstances, Alnylams license under this Agreement will become paid-up; (b) notwithstanding such license
becoming paid-up, Alnylam will be responsible for the payment to the University, or for the reimbursement to Inex, of the amounts due the University from Inex under the University License Agreement arising out of Alnylams activities under the
licenses granted under this Agreement; (c) such payments will be based on the amounts that would have been due Inex under the LCA had the LCA not been terminated; and (d) except for becoming paid-up, the license granted Alnylam under this
Agreement will not change as a result of such termination. Expiration or termination of this Agreement shall not relieve the parties of any obligation accruing prior to such expiration or termination. Any expiration or termination of this Agreement
shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including without limitation the obligation to pay royalties sold prior to such expiration or
termination.

liable for any act, omission, representation, obligation or debt of any other party, even if informed of such act, omission, representation, obligation or debt.

20.3 Subject to the limitations hereinbefore expressed, this Agreement shall inure to the benefit of and
be binding upon the parties, and their respective successors and permitted assigns.

20.4 No condoning, excusing or overlooking by any party
of any default, breach or non-observance by any other party at any time or times in respect of any covenants, provisos, or conditions of this Agreement shall operate as a waiver of such partys rights under this Agreement in respect of any
continuing or subsequent default, breach or non-observance, so as to defeat in any way the rights of such party in respect of any such continuing or subsequent default or breach and no waiver shall be inferred from or implied by anything done or
omitted by such party, save only an express waiver in writing.

20.5 No exercise of a specific right or remedy by any party precludes it from
or prejudices it in exercising another right or pursuing another remedy or maintaining an action to which it may otherwise be entitled either at law or in equity.

20.6 Marginal headings as used in this Agreement are for the convenience of reference only and do not form a part of this Agreement and are not be used in the interpretation hereof.

20.7 The terms and provisions, covenants and conditions contained in this Agreement which by the terms hereof require their performance by the parties
hereto after the expiration or termination of this Agreement shall be and remain in force notwithstanding such expiration or other termination of this Agreement for any reason whatsoever.

20.8 If any Article, part, section, clause, paragraph or subparagraph of this Agreement shall be held to be indefinite, invalid, illegal or otherwise voidable or unenforceable, the entire agreement shall
not fail on account thereof, and the balance of the Agreement shall continue in full force and effect.

20.9 [Intentionally omitted]

20.10 All amounts due and owing to Inex hereunder but not paid by Alnylam on the due date thereof shall bear interest in Canadian dollars at
the rate of one per cent (1%) per month. Such interest shall accrue on the balance of unpaid amounts from time to time outstanding from the date on which portions of such amounts become due and owing until payment thereof in full.

20.11 This Agreement sets forth the entire understanding between the parties and no modifications hereof shall be binding unless executed in writing by
the parties hereto.

20.12 Whenever the singular or masculine or neuter is used throughout this Agreement the same shall be construed as
meaning the plural or feminine or body corporate when the context or the parties hereto may require.
