country, the Product is not sold separately in such country, Net Sales will be calculated by multiplying actual Net Sales of such Combination Product by the fraction (C-B)/C, where B is the average Net Sales price per daily dose of the product
containing the other pharmacologically active ingredients in the Combination Product in such country and C is the average Net Sales price per daily dose of the Combination Product in such country. If, in a specific country, both the Product and the
product containing the other pharmacologically active ingredients in the Combination Product are not sold separately in such country, the Net Sales price for the Product and the product containing the other pharmacologically active ingredients in
the Combination Product will be negotiated by the Parties in good faith based upon the costs, overhead and profit as are then incurred for the Product and all similar substances then being made and marketed by the selling Party and having an
ascertainable market price. 
 Net Sales shall be determined from books and records maintained in accordance with GAAP, consistently applied
throughout the organization and across all products of the entity whose sales of Product are giving rise to Net Sales. 
 1.46

below (all references are to U.S. dollars) with respect to any Alnylam Product that is Covered by a Valid Claim within the Tekmira Royalty-Bearing Patents. Alnylam will provide written notice to Tekmira of the occurrence of a milestone event within
[**] Business Days, and pay the indicated milestone fee to Tekmira within [**] days, after the occurrence of the relevant event. 
 Capitalized
terms in the chart below shall be read in context to apply to Alnylam Products; provided, however, that each milestone payment will be payable no more than once in respect of any given Alnylam Product.

milestone event. The milestone payments described above shall be payable only once in relation to each Alnylam Product that achieves Regulatory Approval in a Major Market (each, a
“Successful Alnylam Product”). Therefore, unless and until there is a Successful Alnylam Product directed to a particular Target, any of the milestone payments made by Alnylam under this Section in connection with an Alnylam Product
directed to such Target shall be fully creditable against the repeated achievement of such milestone event by any other Alnylam Product directed to such Target. However, in the event that there is a Successful Alnylam Product directed to a Target
and Alnylam subsequently begins to Develop or continues to Develop a Follow-On Product, if and when any of the milestone events set out above is thereafter achieved for such Follow-On Product directed to such Target, in addition to the milestone
payment for such milestone event, there will also be due and payable all of the milestone payment(s) for any such milestones that were achieved but not paid for such Follow-On Product prior to the achievement of Regulatory Approval in a Major Market
of a Successful Alnylam Product directed to such Target. 
 4.6 Milestones for Certain Alnylam Existing Exclusive
Targets. In lieu of any milestone payments under Sections 4.4 and 4.5 with respect to all Alnylam Products that are directed to any of the Alnylam Existing Exclusive Targets, a milestone payment will be due by Alnylam to Tekmira solely for the
first achievement of each of the corresponding milestone events set forth in the table below (all references are to U.S. dollars) by the applicable Alnylam Product identified below. Alnylam will provide written notice to Tekmira of the occurrence of
a milestone event within [**] Business Days, and pay the indicated milestone fee to Tekmira within [**] days, after the occurrence of the relevant milestone event. For the avoidance of doubt, each milestone fee set forth below will be payable no
more than once.

 (d) The royalty rate payable on Net Sales of Alnylam Products Covered by one or more Valid
Claims of the Tekmira Royalty-Bearing Patents in the applicable country of sale that are directed to any of the Alnylam Existing Exclusive Targets shall be reduced by [**] of Aggregate Annual Net Sales at all tiers set forth in the tables in
subsections (a) and (b) above (e.g., where such a table indicates a royalty rate of [**]%, the royalty rate that would apply instead with respect to Net Sales of Alnylam Products directed to any of the Alnylam Existing Exclusive
Targets shall be [**]%). 
 4.10 Royalty Reduction. The royalties due under Section 4.8 or 4.9 above, as applicable,
may be reduced on a country-by-country basis in the Territory by the amount of royalties paid or payable with respect to Necessary Third Party IP; provided, however, that royalties due under Section 4.8 or 4.9 above, as
applicable, may not be reduced by more than [**] of the royalties otherwise due (and will not in any case be reduced below [**] of the amount of royalties that would otherwise be due, e.g., for Net Sales of a Tekmira Product up to and
including [**], the minimum effective royalty rate would be [**]%). For purposes of illustration only, if Aggregate Annual Net Sales of a Tekmira Product are [**] and royalties due to Third Parties in respect of the sale of such product total [**]
of Net Sales (or [**]), royalties due to Alnylam may be reduced only by [**] which is determined as follows: maximum reduction is [**] of the royalty due on Net Sales of [**], calculated by [**]. For the avoidance of doubt, royalties paid or payable
by Alnylam pursuant to the Supplemental Agreement or the Sponsored Research Agreement shall constitute royalties paid or payable to Third Parties with respect to Necessary Third Party IP for purposes of this Section 4.10, notwithstanding any
assignment or transfer of the rights to receive such payments to Tekmira or any of its Affiliates; provided, however, that royalties paid or payable pursuant to the Supplemental Agreement or the Sponsored Research Agreement on
Aggregate Annual Net Sales greater than [**] of any Alnylam Product, where such royalties are paid or payable only because such Alnylam Product is Covered by a Valid Claim within the Category 1 Patents (i.e., where such royalties would not be
paid or payable based on other patent rights in the absence of such Category 1 Patents), shall not result in a reduction to royalties under this Agreement pursuant to this Section 4.10 of more than [**]% of such Aggregate Annual Net Sales
greater than [**] in respect of any such Alnylam Product. 
 4.11 Third Party License Payments. Tekmira shall pay 100% of
all royalties, license fees, milestones and similar payments (if any) payable to any Third Party under its existing in-licenses, if any, for the rights to Tekmira Combined Licensed Technology licensed to Alnylam under this Agreement. In addition,
notwithstanding the differences between the milestones and royalties payable by Alnylam under this Agreement and the milestones and royalties that were payable under the Alnylam-Tekmira LCA, Tekmira remains solely responsible for, and agrees to pay
to UBC, any and all amounts payable to UBC pursuant to the Tekmira-UBC License Agreement, including, without limitation, any and all amounts payable to UBC in connection with Alnylam’s exercise of its rights under the UBC Sublicense and any and
all amounts paid by Alnylam to Tekmira under this Agreement or the UBC Sublicense. Alnylam shall pay 100% of all royalties, license fees, milestones and similar payments (if any) payable to any Third Party under any Alnylam Existing In-License for
the rights to Alnylam Licensed Technology licensed to Tekmira under this Agreement.

 4.12 Reports. As to each Royalty Quarter commencing with the Royalty Quarter during
which the First Commercial Sale occurs with respect to a Tekmira Product, in the case of Tekmira as the reporting Party, or with respect to an Alnylam Product, in the case of Alnylam as the reporting Party, within [**] days after the end of such
Royalty Quarter (if the reporting Party has not entered into an agreement with a Sublicensee) and within [**] days after the receipt by the reporting Party from a Sublicensee of such Sublicensee’s report, as required by such Sublicensee’s
sublicense for each Royalty Quarter (if the applicable Party has entered into an agreement with a Sublicensee), each reporting Party will deliver to the other Party to this Agreement a written report showing, on a country-by-country basis, the Net
Sales of Products calculated under GAAP and its royalty obligation for such quarter with respect to such Net Sales under this Agreement together with wire transfer of an amount equal to such royalty obligation. All Net Sales will be segmented in
each such report according to sales by the selling Party and each of its Affiliates and Sublicensees, as well as on a product-by-product basis, including the rates of exchange used to convert Net Sales to United States Dollars from the currency in
which such sales were made. For the purposes of this Agreement, the rates of exchange to be used for converting Net Sales to United States Dollars will be the simple average of the selling and buying rates of U.S. dollars published in The Wall
Street Journal East Coast Edition for the last Business Day of the Royalty Quarter covered by the report. 
 4.13 Tax
Withholding. Each paying Party will use all reasonable and legal efforts to reduce tax withholding with respect to payments to be made to the other Party under this Agreement. Notwithstanding such efforts, subject to Sections 4.1 and 4.2, if the
paying Party concludes that tax withholdings under the laws of any country are required with respect to payments, the paying Party will make the full amount of the required payment to such other Party after any tax withholding. In any such case, the
paying Party shall provide such other Party with a written explanation of such withholding and original receipts or other evidence reasonably desirable and sufficient to allow it to document such tax withholdings for purposes of claiming foreign tax
credits and similar benefits. 
 4.14 Payments. Unless otherwise agreed by the Parties, all payments required to be made
under this Agreement will be made in United States Dollars via wire transfer to an account designated in advance by the receiving Party. 
 4.15 Audits. At any given point in time, each Party will have on file and will require its Affiliates and Sublicensees to have on file complete and accurate records for the last [**] years of all
Net Sales of Products for which it is the paying Party. The other Party to this Agreement will have the right, [**] during each twelve (12) month period, to retain at its own expense an independent qualified certified public accountant
reasonably acceptable to such Party to review such records solely for accuracy and for no other purpose upon reasonable notice and under a written obligation of confidentiality, during regular business hours. If the audit demonstrates that the
payments owed under this Agreement have been understated, the audited Party will pay the balance to such other Party together with interest on such amounts from the

date on which such payment obligation accrued at a rate equal to the then current [**] United States dollar LIBOR rate plus [**] percent per annum. If the underpayment is greater than five
percent of the amount owed, then the audited Party will reimburse such other Party for its reasonable out-of-pocket costs of the audit. If the audit demonstrates that the payments owed under this Agreement have been overstated, such other Party to
this Agreement will credit the balance against the next payment due from the audited Party (without interest).

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 obligations. Confidential Information that is disclosed by judicial or administrative process shall

Sublicensees.

treatment with, any Tekmira Product Covered by an Alnylam Patent, whether claimed by reason of breach of warranty, negligence or product defect, and (b) any breach of any representation, warranty or covenant of Tekmira in this Agreement.

 The above indemnification shall not apply to the extent that any Losses are due to a breach of any of Alnylam’s representations,
warranties, covenants and/or obligations under this Agreement. 
 7.2 Alnylam Indemnification. Alnylam agrees to
indemnify and hold harmless Tekmira, its Affiliates, and their respective agents, directors, officers and employees and their respective successors and permitted assigns (the “Tekmira Indemnitees”) from and against any and all Losses
incurred by a Tekmira Indemnitee arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a Third Party based on (a) any claim made against Tekmira by Third Parties regardless of the form or forum in
which any such claim is made alleging (i) infringement or misappropriation of Third Party intellectual property, or (ii) personal injury, or death occurring to any person claimed to result, directly or indirectly, from the possession, use
or consumption of, or treatment with, any Alnylam Product Covered by a Tekmira Patent, whether claimed by reason of breach of warranty, negligence or product defect, and (b) any breach of any representation, warranty or covenant of Alnylam in
this Agreement.

 The above indemnification shall not apply to the extent that any Losses are due to a breach of any of
Tekmira’s representations, warranties, covenants and/or obligations under this Agreement. 
 7.3 Tender of Defense;
Counsel. The obligation to indemnify pursuant to this Article shall be contingent upon timely notification by the indemnitee to the indemnitor of any claims, suits or service of process; the tender by the indemnitee to the indemnitor of full
control over the conduct and disposition of any claim, demand or suit; and reasonable cooperation by the indemnitee in the defense of the claim, demand or suit. No indemnitor will be bound by or liable with respect to any settlement or admission
entered or made by any indemnitee without the prior written consent of the indemnitor. The indemnitee will have the right to retain its own counsel to participate in its defense in any proceeding hereunder. The indemnitee shall pay for its own
counsel except to the extent it is determined that (a) one or more legal defenses may be available to it which are different from or additional to those available to the indemnitor, or (b) representation of both Parties by the same counsel
would be inappropriate due to actual or potential differing interests between them. In any such case and to such extent, the indemnitor shall be responsible to pay for the reasonable costs and expenses of one separate counsel retained to participate
in the defense of the indemnitee, provided that such expenses are otherwise among those covered by the indemnitor’s indemnity obligations under this Article VII. Notwithstanding the foregoing, if the indemnitor reasonably believes that any of
the exceptions to its obligation of indemnification of the indemnitee set forth in Sections 7.1 or 7.2 may apply, the indemnitor shall promptly notify the indemnitee, which shall then have the right to be represented in any such action or proceeding
by separate counsel at the indemnitee’s expense; provided, that the indemnitor shall be responsible for payment of such expenses if the indemnitee is ultimately determined to be entitled to indemnification from the indemnitor.

force and effect throughout the term of the licenses set out in Section 2.1 (and for at least [**] years thereafter for claims-made coverage), the following types and amounts of insurance coverage with carriers having a minimum AM Best rating
