receiving Party provides prior written notice of such disclosure to the disclosing Party and takes reasonable and lawful actions to avoid or minimize the extent of such disclosure.
|------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If a Party is required by judicial or administrative process to disclose Confidential Information that is subject to the non-disclosure
provisions of this Section 14.1.1, 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 obligations. Confidential
Information that is disclosed by judicial or administrative process shall remain otherwise subject to the confidentiality and non-use provisions of this Section 14.1.1, and the Party disclosing Confidential Information pursuant to law or court
order shall take all steps reasonably practical,

including without limitation seeking an order of confidentiality, to ensure the continued confidential treatment of such Confidential Information. In addition to the foregoing restrictions on
public disclosure, if either Party concludes that a copy of this 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 seek the
maximum confidential treatment available under applicable law, provide the other Party with a copy of this Agreement showing any sections as to which the Party proposes to request confidential treatment, provide the other Party with an opportunity
to comment on any such proposal and to suggest additional portions of this Agreement for confidential treatment, and take such Partys reasonable comments into consideration before filing this Agreement.



|14.1.2 | Each Party agrees that it will provide Confidential Information received from the other Party solely to its employees, consultants and advisors, and the employees,
consultants and advisors of its Affiliates or Back-Up Manufacturers as applicable, who have a legitimate business need to know and an obligation to maintain in confidence the Confidential Information of the disclosing Party. The disclosing Party is
liable for any breach of the non-disclosure obligation of its consultants, advisors, Affiliates and Back-Up Manufacturers as applicable.

a copy of the proposed written publication or an outline of an oral disclosure at least thirty (30) days prior to submission for publication or presentation. The reviewing Party shall have the right (a) to propose modifications to the
publication or presentation for patent reasons, trade secret reasons or business reasons, or (b) 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 thirty (30) days to enable patent applications protecting each Partys rights in such information to be filed. Upon expiration of such thirty (30) days, the
publishing Party shall be free to proceed with the publication or presentation. If the reviewing Party requests modifications to the publication or presentation, the publishing Party shall edit such publication to prevent disclosure of trade secret
or proprietary business information prior to submission of the publication or presentation. 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 14.1.3 to the extent that Tekmira or Alnylam, as the case may be, has the right and ability (after using reasonable efforts) to do so.

|---- | -----------------

Each Party
acknowledges the competitive and technical value and the sensitive and confidential nature of the Confidential Information and agrees that monetary damages alone will be inadequate to protect the other Partys interests against any actual or
threatened material breach of Section 14.1 of this Agreement. Accordingly, each Party consents to the granting of specific performance and injunctive or other equitable relief to the other Party in respect of any actual or threatened breach of
Article 11 and Section 14.1 of this Agreement, without proof of actual Damages. These specific remedies are in addition to any other remedy to which the Parties may be entitled at law or in equity.

|15.3 | Remedy
|---- | ------

The indemnification provided for
in this Agreement will not be exclusive and will not be in lieu of any other remedies available to a Party hereto for any default hereunder on the part of the other Party.



|15.4 | LIMITATION OF LIABILITY
|---- | -----------------------

NEITHER PARTY
HERETO WILL BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER OR THEREUNDER, INCLUDING LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT,
REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT AS A RESULT OF A PARTYS WILLFUL MISCONDUCT OR A MATERIAL BREACH OF THE CONFIDENTIALITY AND NON-USE OBLIGATIONS IN ARTICLE 14. NOTHING IN THIS SECTION 15.4 IS INTENDED TO LIMIT OR RESTRICT THE
INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY.



|15.5 | Notice and Opportunity To Defend
|---- | --------------------------------

Promptly after receipt by a Party hereto of notice of any claim which could give rise to a right to indemnification pursuant to Sections 15.1 or 15.2,
such Party (the Indemnified Party) will give the other Party (the Indemnifying Party) written notice describing the claim in reasonable detail. The failure of an Indemnified Party to give notice in the manner
provided herein will not relieve the Indemnifying Party of its obligations under this Section, except to the extent that such failure to give notice materially prejudices the Indemnifying Partys ability to defend such claim. The Indemnifying
Party will have the right, at its option, to compromise or defend, at its own expense and by its own counsel, any such matter involving the asserted liability of the Party seeking such indemnification. If the Indemnifying Party will undertake to
compromise or defend any such asserted liability, it will promptly (and in any event not less than ten (10) Business Days after receipt of the Indemnified Partys original notice) notify the Indemnified Party in writing of its intention to
do so, and the Indemnified Party agrees to cooperate fully with the Indemnifying Party and its counsel in the compromise or defence against any such asserted liability. All reasonable costs and expenses incurred in connection with such co-operation
will be borne by the Indemnifying Party. If the Indemnifying Party elects not to compromise or defend the asserted liability, fails to notify the Indemnified Party of its election to compromise or defend as herein provided, fails to admit its
obligation to indemnify under this Agreement with respect to the claim, or, if in the reasonable opinion of the Indemnified Party, the claim could result in the Indemnified Party becoming subject to injunctive relief or relief other than the payment
of money damages that could materially adversely affect the ongoing business of the Indemnified Party in any manner, the Indemnified Party will have the right, at its option, to pay, compromise or defend such asserted liability by its own counsel
and its reasonable costs and expenses will be included as part of the indemnification obligation of the Indemnifying Party hereunder. Notwithstanding the foregoing, neither the Indemnifying Party nor the Indemnified Party may settle or compromise
any claim over the objection of the other; provided however, that consent to settlement or compromise will not be unreasonably withheld. In any event, the Indemnified Party and the Indemnifying Party may participate, at their own expense, in the
defence of such asserted liability. If the Indemnifying Party chooses to defend any claim, the Indemnified Party will make available to the Indemnifying Party any books, records or other documents within its control that are necessary or appropriate
for such defence. Notwithstanding anything to the contrary in this Section 15.5, (i) the Party conducting the defence of a claim will (A) keep the other Party informed on a reasonable and timely basis as to the status of the defence
of such claim, and (B) conduct the defence of such claim in a prudent manner, and (ii) the Indemnifying Party will not cease to defend, settle or otherwise dispose of any claim without the prior written consent of the Indemnified Party
(which consent will not be unreasonably withheld).

required to be effected and maintained herein, and each Party will, within thirty (30) days following such request, provide current copies of said documentation. The insured shall endeavour to provide thirty (30) days prior written notice

|---- | ------------------



|16.6.1 | Disputes.The Parties shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising from, or related to, this
Agreement or to the breach hereof (collectively, Dispute). In the event that the Executive Officers cannot reach an agreement regarding a Dispute within thirty (30) days after submission to them for resolution and a Party
wishes to pursue the matter, each such Dispute that is not an Excluded Claim shall be finally resolved by binding arbitration in accordance with the Commercial Arbitration Rules and Supplementary Procedures for Large
Complex Disputes of the American Arbitration Association (AAA) and Section 16.6.2 below, and judgment on the arbitration award may be entered in any court having jurisdiction thereof. As used in this Section 16.6, the
term Excluded Claim shall mean a dispute that concerns (a) the validity or infringement of a patent, trademark or copyright, or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

|16.6.2 | Arbitration. The arbitration shall be conducted by a panel of three (3) persons experienced in the pharmaceutical business who are independent of both
Parties and neutral with respect to the Dispute presented for arbitration. Within thirty (30) days after initiation of arbitration, each Party shall select one person to act as arbitrator and the two Party-selected arbitrators shall select a
third arbitrator within thirty (30) days of their appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the AAA. The place of arbitration shall
be Chicago, Illinois, USA, and all proceedings and communications shall be in English. Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either
Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators
shall have no authority to award punitive or any other type of damages not measured by a Partys compensatory damages. Each Party shall bear its own costs and expenses and attorneys fees, and the Party that does not prevail in the
arbitration proceeding shall pay the arbitrators and any administrative fees of arbitration. Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may disclose the existence,
content, or results of an arbitration without the prior written consent of both Parties. In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the Dispute, controversy or claim
would be barred by the applicable Massachusetts statute of limitations.

obligations will be suspended during the period of such disability. The Party prevented from performing hereunder will use commercially reasonable efforts to remove such disability and will continue performance of the affected obligations whenever
such causes are removed provided that the Party will throughout the period of disability continue performance of the non-affected obligations. The Party so affected will give to the other Party a good faith estimate of the continuing effect of the
force majeure condition and the duration of the affected Partys non-performance. If any raw materials, facility systems or capacity is used for both the affected Product and any other products or purposes, any necessary allocation will be
made, on a substantially pro rata basis, as between Tekmiras needs (including those of any Affiliate of Tekmira), Alnylams needs and the needs of any other Party to whom Tekmira has firm contractual obligations. If the period of any
previous actual non-performance of Tekmira because of Tekmira force majeure conditions plus the anticipated future period of Tekmira non-performance because of such conditions will exceed an aggregate of one hundred eighty (180) days within any
twenty-four (24) month period, Alnylam may terminate this Agreement by notice to Tekmira and any orders for Product then outstanding will be deemed cancelled. If the period of any previous actual non-performance of Alnylam because of Alnylam
force majeure conditions plus the anticipated future period of Alnylam non-performance because of such conditions will exceed an aggregate of one hundred eighty (180) days within any twenty-four (24) month period, Tekmira may terminate
this Agreement by notice to Alnylam and any orders for Product then outstanding will be deemed cancelled. When such circumstances as those contemplated herein arise, the Parties will discuss in good faith, what, if any, modification of the terms set
forth herein may be required in order to arrive at an equitable solution.
