Protiva shall pay the cost of such audit unless it discovers that Licensee has underreported aggregate Gross Profits during any year in the Record Retention Period to Protiva by an amount of at least [***], in which case the costs of such audit shall be borne by Licensee.

3.2    Payment for License    .

(a)    As consideration for the Transferred Protiva Rights, and in full satisfaction of the Protiva Purchase Price, the Licensee (i) issued to Protiva the Protiva Note, (ii) issued to Protiva one Class B Common share without par value in the capital stock of the Licensee as a fully paid and non-assessable share, and (iii) granted to Protiva the rights set out in Section 3.3.

(b)    As consideration for the Transferred Tekmira Rights, and in full satisfaction of the Tekmira Purchase Price, the Licensee issued to Tekmira one Class A Common share without par value in the capital stock of the Licensee as a fully paid and non-assessable share. [***].

(ii)    if permitted under the Tax Act or the administrative discretion of the Canada Revenue Agency, Protiva at its sole discretion may file an amended election under subsection 85(7.1) of the Tax Act along with the appropriate penalty payment reporting a new fair market value of the Transferred Protiva Rights based on the amounts determined pursuant to section 3.4(b)(i) of this Agreement.

(c)    If the Canada Revenue Agency or any other competent authority at any time hereafter proposes to issue or issues any assessment or assessments, on the basis that the Protiva Elected Amount set out in the Protiva Election is greater or less than the applicable Tax Values of the Transferred Protiva Rights, then:

(i)    upon the applicable Tax Values being finally determined, by the Agreement of Protiva and the Licensee with the Canada Revenue Agency if they do so agree, or by final determination by a court of competent jurisdiction if they do not, the Protiva Elected Amount will be deemed conclusively to have always been such finally determined Tax Value; and

(ii)    if permitted under the Tax Act or the administrative discretion of the Canada Revenue Agency, Protiva at its sole discretion may file an amended election under subsection 85(7.1) of the Tax Act along with the appropriate penalty payment electing such amount as is deemed to be the Protiva Elected Amount under Section 3.4(c)(i).

(d)    If the Canada Revenue Agency or any other competent authority at any time hereafter proposes to issue or issues any assessment or assessments on the basis that the fair market value of the Transferred Tekmira Rights at the time of transfer is greater or less than the Tekmira Purchase Price, then:

(i)    upon the fair market value of the Transferred Tekmira Rights being finally determined by the agreement of Arbutus and the Licensee with the Canada Revenue Agency if they

do so agree, or by final determination by a court of competent jurisdiction if they do not, the Tekmira Purchase Price will be deemed conclusively to have always been the amount so determined, and this Agreement will be deemed to be amended as of the Effective Date to reflect such Tekmira Purchase Price as determined under this Section 3.5(b)(i); and

(ii)    if permitted under the Tax Act or the administrative discretion of the Canada Revenue Agency, Arbutus at its sole discretion may file an amended election under subsection 85(7.1) of the Tax Act along with the appropriate penalty payment reporting a new fair market value of the Transferred Tekmira Rights based on the amounts determined pursuant to section 3.5(b)(i) of this Agreement.

4.1    Termination of Services Obligations. The Parties acknowledge and agree that, as of the Effective Date, Monsanto Canada is exercising the Call Option prior to completion of Phase C (as such term is defined in the Research Program). Monsanto Canada hereby elects to terminate research under the Research Plan as of the Effective Date and, therefore, the Parties acknowledge and agree that, on and as of the Effective Date, Protiva’s obligation to provide Services under this Agreement terminates; provided, however, that, for the avoidance of doubt, from and after the Effective Date, Protiva remains obligated to provide the Technology Transfer in accordance with the Option Agreement through completion of the Technology Transfer in accordance with the Technology Transfer Completion Criteria.

5.1    Ownership. Subject to the licenses granted by Protiva herein, Protiva is and shall at all times remain the owner of the Protiva Intellectual Property, including, for the avoidance of doubt, Protiva Project Patents. As more particularly set forth in the Protiva-Monsanto Services Agreement, and subject to the license granted by Monsanto in the Protiva-Monsanto Services Agreement, Monsanto is and shall at all times remain owner of any Joint Project Intellectual Property.

5.2    Prosecution and Maintenance of Patents.

(a)    Subject to Section 5.6, Protiva shall have the sole right and responsibility, in its sole discretion and at its sole cost and expense, to file, prosecute, maintain and/or abandon patent protection in the Territory for Protiva Background Patents.

(b)    During the Term, decisions regarding the filing of Patent protection in the Territory for Protiva Project Inventions and decisions regarding the prosecution, maintenance and/or abandonment of Protiva Project Patents in the Territory shall be made by Protiva and/or the JRC in accordance with the applicable provisions of the Option Agreement and, subject to and in accordance with such provisions, Protiva shall be responsible for implementing Protiva’s and/or the JRC’s decisions regarding the filing, prosecution, maintenance, and/or abandonment of Protiva Project Patents in the Territory. Except as otherwise set out in the Option Agreement, all costs and fees incurred in connection with the filing, prosecution, maintenance and/or abandonment of all Protiva Project Patents through the Effective Date shall be the sole responsibility of Protiva; all costs and fees incurred in connection with the filing, prosecution, maintenance and/or abandonment of all Protiva Project Patents after the Effective Date shall be the sole responsibility of Licensee.

(a)    Each Party shall promptly report in writing to the other Party during the Term known or suspected commercially relevant infringement by a Third Party of any of the Protiva Background Patents in any field and any known or suspected infringement by a Third Party of any of the Protiva Background Patents in the Agricultural Field of which such Party becomes aware and shall provide the other Party with all evidence supporting or relating to such infringement in its possession.

(b)    Protiva shall have the sole and exclusive right to initiate an infringement or other appropriate suit with respect to infringements or suspected infringements of any of the Protiva Background Patents, or to take such other actions as Protiva, in its sole discretion, deems appropriate with respect to such infringements or suspected infringements (“Background Patent Infringement Action”). Protiva shall notify Licensee promptly after initiating any Background Patent Infringement Action.

(c)    With respect to any Background Patent Infringement Action initiated on or after the Effective Date directed to infringement occurring at least in part in the Agricultural Field: (i) Licensee may join such Infringement Action as a party if it has standing to do so (at its own cost and expense), may retain counsel at its own cost and expense to provide advice to Licensee regarding such Infringement Action, and may share all information regarding the Infringement Action provided by Protiva with such counsel, and, if Licensee has joined such Infringement Action, such counsel shall be permitted to attend meetings, discussions, or other activities relating to the Infringement Action on behalf of Licensee; and (ii) Provita agrees to give due consideration to any recommendations or suggestions of Licensee in connection with the Infringement Action, but shall not be obligated to implement or follow any such recommendations or suggestions. After the Effective Date, Protiva shall not enter into any settlement or compromise in connection with any Background Patent Infringement Action that would eliminate, diminish, or otherwise modify any right, title, or interest of the Licensee in any Protiva Intellectual Property or that would require any payments, concessions,

or otherwise bind the Licensee, without the Licensee’s prior written consent, which consent shall not be unreasonably withheld; for the avoidance of doubt, any settlement or compromise that permits continuation of Licensee’s rights in and to Protiva Intellectual Property in the same manner and subject to the same terms and conditions as set forth in this Agreement shall not require Licensee’s prior consent. Licensee shall provide reasonable cooperation and assistance in connection with a Background Patent Infringement Action initiated by Protiva (including being joined as a party in such Background Patent Infringement Action) at Protiva’s reasonable request and sole cost.

5.4    Third-Party Infringement of Protiva Project Patents.

(a)    Each Party shall promptly report in writing to the other Party during the Term known or suspected commercially relevant infringement by a Third Party of any of the Protiva Project Patents in any field and any known or suspected infringement by a Third Party of any of the Protiva Project Patents in the Agricultural Field of which such Party becomes aware and shall provide the other Party with all evidence supporting or relating to such infringement in its possession.

(b)    Protiva shall have the right, but not the obligation, to initiate an infringement or other appropriate suit with respect to infringements or suspected infringements of any of the Protiva Project Patents, or to take such other actions as Protiva, in its sole discretion, deems appropriate with respect to such infringements or suspected infringements (“Project Patent Infringement Action”). If Protiva declines to commence a Project Patent Infringement Action with respect to a particular actual or threatened infringement of any issued patent within the Protiva Project Patents (an “Identified Infringement”) within sixty (60) days following its receipt of a written request from Licensee that it initiate a Project Patent Infringement Action with respect to such Identified Infringement, or if Protiva otherwise fails to confirm that it will commence a Project Patent Infringement Action with respect to such Identified Infringement within such sixty (60) day period, then Licensee may thereafter commence a Project Patent Infringement Action with respect to such Identified Infringement. Licensee shall use reasonable best efforts to notify Protiva prior to initiating any Project Patent Infringement Action and shall continue to inform Protiva of the status of any Project Patent Infringement Action initiated by Licensee, including by responding to Protiva’s reasonable requests for status reports, providing drafts of substantive filings of Licensee prior to the due date for such filings, and providing copies of substantive filings of any other party to any such Project Patent Infringement Action promptly after receiving such filings. If any monetary judgment or settlement is recovered in connection with any Project Patent Infringement Action initiated by Licensee or Protiva in accordance with this Section 5.4(b), then, after Licensee or Protiva, as applicable, recoups actual costs and reasonable expenses associated with such Project Patent Infringement Action, (i) then if the monetary judgment or settlement is primarily attributable to infringement in the Agricultural Field, Licensee shall be entitled to receive from the remainder an amount equal to all direct damages attributable to infringement in the Agricultural Field awarded in such judgment or payable under such settlement; Protiva shall then be entitled to receive from the remainder after such payment to Licensee, if any, an amount equal to all direct damages attributable to infringement outside of the Agricultural Field awarded in such judgment or payable under such settlement; and the balance, if any, remaining after such payments to Licensee and Protiva shall be allocated and payable [***] to Licensee and [***] to Protiva; or (ii) if the monetary judgment or settlement is primarily attributable to infringement outside of the Agricultural Field,

Protiva shall be entitled to receive from the remainder an amount equal to all direct damages attributable to infringement outside of the Agricultural Field awarded in such judgment or payable under such settlement, Licensee shall then be entitled to receive from the remainder after such payment to Protiva, if any, an amount equal to all direct damages attributable to infringement in the Agricultural Field awarded in such judgment or payable under such settlement; and the balance, if any, remaining after such payments to Protiva and Licensee shall be allocated and payable [***] to Licensee and [***] to Protiva.

(c)    Protiva shall use reasonable best efforts to notify Licensee prior to initiating any Project Patent Infringement Action and shall continue to inform Licensee of the status of any Project Patent Infringement Action initiated by Protiva, including by responding to Licensee’s reasonable requests for status reports, providing drafts of substantive filings of Protiva prior to the due date for such filings, and providing copies of substantive filings of any other party to any such Infringement Action promptly after receiving such filings.

(d)    Each Party (as a “Non-Initiating Party”), with respect to a Project Patent Infringement Action initiated by the other Party (as an “Initiating Party”), may join such Infringement Action as a party if it has standing to do so (at its own cost and expense), may retain counsel at its own cost and expense to provide advice to the Non-Initiating Party regarding such Infringement Action, and may share all information regarding the Infringement Action provided by the Initiating Party with such counsel, and, if the Non-Initiating Party has joined such Infringement Action, such counsel shall be permitted to attend meetings, discussions, or other activities relating to the Infringement Action on behalf of the Non-Initiating Party. The Initiating Party agrees to give due consideration to any recommendations or suggestions of the Non-Initiating Party in connection with a Project Patent Infringement Action, but shall not be obligated to implement or follow any such recommendations or suggestions; provided however, that the Initiating Party shall not enter into any settlement or compromise in connection with a Project Patent Infringement Action that would eliminate, diminish, or otherwise modify any right, title, or interest of the Non-Initiating Party in any Protiva Intellectual Property or that would require any payments, concessions, or otherwise bind the Non-Initiating Party, without the Non-Initiating Party’s prior written consent, which consent shall not be unreasonably withheld; for the avoidance of doubt, any settlement or compromise that permits continuation of the Non-Initiating Party’s rights in and to Protiva Intellectual Property in the same manner and subject to the same terms and conditions as set forth in this Agreement shall not require the Non-Initiating Party’s prior consent. The Non-Initiating Party shall provide reasonable cooperation and assistance in connection with a Project Patent Infringement Action initiated by the Initiating Party (including being joined as a party in such Project Patent Infringement Action) at the Initiating Party’s reasonable request and sole cost.

5.5    Defense of Claims Brought by Third Parties    . Each Party shall promptly notify the other Party if it becomes aware of any claim that Licensee’s actual use or practice of Compounds or Formulations within the Protiva Intellectual Property, or Licensee’s methods of creating or using such Formulations or Compounds, in connection with its exercise of its license under Section 2.1 infringes, misappropriates, or otherwise violates the intellectual property rights of any Third Party in the Agricultural Field. In any such instance, the Parties shall cooperate and shall mutually agree upon an appropriate course of action; provided, however, that in the absence of any such agreement,

(i) any such matter relating to Protiva Project Patents (such matter a “JRC Protiva Project Infringement Matter”) shall be referred to the JRC to be addressed in the manner set forth in the Option Agreement, and (ii) Protiva shall have sole right to determine what action, if any, should be taken in respect of Protiva Background Patents. Each Party shall provide to the other Party copies of any notices it receives from Third Parties regarding any patent nullity actions regarding the Protiva Background Patents or the Protiva Project Patents, any declaratory judgment actions and any alleged infringement or misappropriation of Third Party intellectual property rights arising out of Licensee’s use or practice of the Protiva Intellectual Property in connection with its exercise of its license under Section 2.1. Each Party shall be responsible for its own costs incurred pursuant to this Section 5.5; provided, however, that nothing in this Section 5.5 or elsewhere in this Agreement shall be deemed to eliminate, reduce, or otherwise modify any liability or obligation of Protiva in respect of the Protiva Intellectual Property or Licensee’s (or its Sublicensees’) use or practice of the Protiva Intellectual Property in connection with its exercise of its license under Section 2.1, including but not limited to any such liability or obligation that may arise out of any representation, warranty, or covenant made by Protiva under the Option Agreement or any other Transaction Agreement; and provided further, however, that nothing in this Section 5.5 shall be deemed to limit or eliminate a Party’s right to defend actions initiated by a Third Party against such Party, except to the extent such rights may be limited under any indemnification provisions applicable to such actions.

5.6    Disclosures and Opt-In Rights Regarding Protiva Background Patents. If, during the Term, Protiva decides not to pay the maintenance fee, annuity fee, or similar fee due on any Protiva Background Patent or decides to abandon or discontinue prosecution of any Protiva Background Patent (each a “Proposed Abandonment”) and if (a) such Proposed Abandonment will not be accompanied by the proper filing of a continuation or continuation-in-part application for a Protiva Background Patent and (b) there will be no remaining Protiva Background Patent in the same country or jurisdiction in which the abandoned or discontinued Protiva Background Patent was filed that will substantially maintain the value of Licensee’s exclusive license under the Protiva Background Patents in the Agricultural Field, Protiva shall notify Licensee at least sixty (60) days in advance of any applicable administrative deadline, maintenance fee due date, or response date after or upon which such Protiva Background Patent will be or become abandoned or trigger a similar loss of rights in jurisdictions other than the United States (the “Response Deadline”), such notice to include the Response Deadline. Upon written request of Licensee, Protiva shall promptly assign to Licensee all of its right, title, and interest in and to such Protiva Background Patent unless (x) such Protiva Background Patent is assigned to a Third Party who takes all steps necessary to prevent the Proposed Abandonment and (y) Licensee retains its license to such Protiva Background Patent on the terms and conditions set forth in this Agreement; Protiva shall thereafter have no further right, title, or interest in or to such Protiva Background Patent, except that Protiva shall thereafter have a perpetual, fully paid-up, non-exclusive right and license under such Protiva Background Patent for all uses in the Protiva Field. To the extent necessary or appropriate to prevent the abandonment or similar loss of rights of a Protiva Background Patent assigned or to be assigned to Licensee, Protiva shall take such other steps (including submission of filings or payments on behalf of Licensee or Monsanto) that are reasonably requested by Licensee (or Monsanto), at Licensee’s (or Monsanto’s) sole cost and expense.

5.7    Joint Research Committee Oversight. From and after termination of the Option Agreement, then until the disbandment of the JRC by unanimous vote of the JRC at any time after expiration of the last to expire Valid Claim of a Protiva Project Patent or a Joint Project Patent, the JRC shall remain in existence and shall perform the functions described in this Agreement and any other Transaction Agreements according to the general processes and procedures set out in the Option Agreement (as such processes and procedures may be modified by the unanimous vote of the JRC). For the avoidance of doubt, the JRC’s oversight of Protiva Project Patents shall terminate if this Agreement terminates.

6.1    Non-Disclosure of Confidential Information    . Each Party agrees that, for itself and its Affiliates, until the first to occur of (i) [***] or (ii) [***], a Receiving Party shall maintain all Confidential Information of the Disclosing Party in strict confidence and shall not (a) disclose Confidential Information to any third party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below or (b) use Confidential Information for any purpose except those explicitly licensed or otherwise authorized or permitted by this Agreement or any other Transaction Agreement.

6.2    Exceptions    . The obligations in Section 6.1 will not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent proof: (i) was known to the Receiving Party or its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party; (ii) is subsequently disclosed to the Receiving Party or its Affiliates by a Third Party lawfully in possession thereof and without any obligation to keep it confidential or any restriction on its use; (iii) is or otherwise becomes generally available to the public or enters the public domain, either before or after it is disclosed to the Receiving Party and such public availability is not the result, directly or indirectly, of any fault of, or improper taking, use or disclosure by, the Receiving Party or its Affiliates or anyone working in concert or participation with the Receiving Party or its Affiliates; or (iv) has been independently developed by employees or contractors of the Receiving Party or its Affiliates without the aid, application or use of Confidential Information of the Disclosing Party. Specific Confidential Information disclosed by a Disclosing Party will not be deemed to be within any exceptions set forth in (i), (ii), or (iii) above merely because it is embraced by more general information to which one or more of those exceptions may apply and provided further that no combination of information shall be deemed to be within any such exceptions unless the combination itself and its principle of operation are within the public domain. Even though Confidential Information may be within one of the exceptions described in the preceding sentence, the Receiving Party shall not disclose to third parties that the excepted Confidential Information was received from the Disclosing Party.

6.3    Permitted Uses. Confidential Information of a Disclosing Party may be used by the Receiving Party in the performance of its obligations under any Transaction Agreement, as otherwise expressly authorized in any Transaction Agreement or as expressly authorized by the Disclosing Party in writing. Confidential Information that is Protiva Intellectual Property may be used by Licensee subject to and in accordance with the provisions of this Agreement applicable to Licensee’s license to Protiva Intellectual Property. Licensee shall take steps to maintain the confidentiality of

such Confidential Information that are consistent with the steps it takes to maintain the confidentiality of its own most-valuable confidential information, but in no event less than commercially reasonable steps; provided, however, that nothing in this Agreement shall be deemed to eliminate, restrict, or otherwise limit Licensee’s license to use such Confidential Information in accordance with the terms and conditions of this Agreement, even if such use may result, directly or indirectly, in the disclosure of such Confidential Information, so long as such disclosures are made in a manner than complies with Section 6.4 below.

6.4    Permitted Disclosures. The Receiving Party may disclose Confidential Information belonging to the Disclosing Party to the extent (and only to the extent) such disclosure is reasonably necessary in the following instances: (i) subject to the proviso below, by any Party hereto, in order to comply with applicable non-patent law (including any securities law or regulation or the rules of a securities exchange in a relevant jurisdiction) and with judicial process, if based on the reasonable advice of the Receiving Party’s counsel, such disclosure is necessary for such compliance; (ii) subject to the proviso below, by any Party hereto, in connection with prosecuting or defending litigation; (iii) by any Party hereto, in connection with filing and prosecuting Protiva Project Patents and Joint Project Patents only in a manner that complies with such Party’s rights and obligations in connection with such matters as set out in the Transaction Agreements; (iv) subject to the proviso below, by Licensee, its Sublicensees, or their sublicensees in connection with any legal or regulatory requirements related to the development, sale, offer for sale, use or manufacture of commercial products (or potential commercial products) that use or employ Protiva Intellectual Property, such as labeling requirements, disclosures in connection with obtaining regulatory approvals, and the like, so long as the discovery, development, use, manufacture, and commercialization of such products has been and is performed in a manner that complies with the terms and conditions of Licensee’s license to such Protiva Intellectual Property and reasonable steps shall be taken to maintain the confidentiality of said Confidential Information even when disclosed for legal or regulatory purposes; (v) subject to the proviso below, by the Licensee, to its Affiliates, permitted acquirers or assignees under the Transaction Agreements and its or any of their research collaborators, subcontractors, lenders (but, with respect to lenders, only Confidential Information related to the terms and conditions of the Transaction Agreements and financial information related thereto), and each of the Licensee’s and its Affiliates’ respective directors, employees, contractors and agents; and (vi) subject to the proviso below, by Protiva, to its Affiliates, permitted acquirers or assignees under the Transaction Agreements and its or any of their research collaborators, subcontractors, lenders (but, with respect to lenders, only Confidential Information related to the terms and conditions of the Transaction Agreements and financial information related thereto), and Protiva’s and its Affiliates’ respective directors, employees, contractors and agents, provided, that (a) with respect to clause (i), (ii) and (iv) where legally permissible, (1) the Receiving Party shall notify the Disclosing Party of the Receiving Party’s intent to make any disclosure pursuant thereto sufficiently prior to making such disclosure so as to allow the Disclosing Party adequate time to take whatever action it may deem appropriate to protect the confidentiality of the information to be disclosed, and (2) consistent with applicable law or regulation, the Disclosing Party shall have the right to suggest reasonable changes to the disclosure to protect its interests and the Receiving Party shall not unreasonably refuse to include such changes in its disclosure, and (b) with respect to clause (v) and (vi), each Person to whom Confidential Information is disclosed must be bound prior to disclosure by confidentiality and non-use restrictions at least as restrictive as those contained

in this Agreement (other than investment bankers, investors and lenders, who must be bound prior to disclosure by commercially reasonable obligations of confidentiality).

7.1    Protiva Indemnification    . Protiva agrees to indemnify Licensee and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Licensee Indemnitees”) against and to hold each of them harmless from any and all losses, costs, damages, fees or expenses (“Losses”) actually incurred or suffered by an Licensee Indemnitee to the extent arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a Third Party based on any breach of any representation, warranty or covenant by Protiva under this Agreement or Protiva’s gross negligence or willful misconduct. The foregoing indemnification shall not apply to the extent that any Losses are due to (a) a breach of any of Licensee’s representations, warranties, covenants and/or obligations under this Agreement or (b) Licensee’s gross negligence or willful misconduct.

7.2    Licensee Indemnification. Licensee agrees to indemnify Protiva and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Protiva Indemnitees”) against and to hold each of them harmless from any and all Losses actually incurred or suffered by a Protiva Indemnitee to the extent arising out of or in connection with (a) any claim, suit, demand, investigation or proceeding brought by a Third Party based on (i) any breach of any representation, warranty or covenant by Licensee under this Agreement, or (ii) Licensee’s gross negligence or willful misconduct, or (b) a Third Party’s direct damages resulting from any development or Commercialization of any Product or products or processes that use or employ Protiva Intellectual Property. In addition to the limitations set forth in the preceding sentence, the foregoing indemnification obligations shall not apply to the extent that any Losses are due to (x) a breach of any of Protiva’s representations, warranties, covenants and/or obligations under this Agreement, (y) Protiva’s gross negligence or willful misconduct, or (z) any of the following occurring prior to or at Closing: (A) any breach of any representation, warranty or covenant by Licensee under this Agreement; (B) Licensee’s gross negligence or willful misconduct; or (C) a breach of any of Protiva’s representations, warranties, or covenants directed to Protiva Intellectual Property or the Protiva License under the Option Agreement.

7.3    Tender of Defense; Counsel    . Any Person (the “Indemnified Party”) seeking indemnification under Article VII agrees to give prompt notice in writing to the other Party (the “Indemnifying Party”) of the assertion of any claim or the commencement of any action by any third party (a “Third Party Claim”) in respect of which indemnity may be sought under such section. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party. The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and shall, upon its written confirmation of its obligation to indemnify the Indemnified Party in accordance with this Article VII, be entitled to control and appoint lead counsel reasonably satisfactory to the Indemnified Party for such defense by written notice to the Indemnified

Party within twenty (20) calendar days after the Indemnifying Party has received notice of the Third Party Claim, in each case at its own expense; provided, however, that the Indemnifying Party must conduct the defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights in this regard. The Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Third Party Claim and shall pay the fees and expenses of one counsel retained by the Indemnified Party if: (a) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment or allegation, (b) the Third Party Claim seeks an injunction or equitable relief against a Indemnified Party or any of its Affiliates, or (c) the Indemnifying Party has failed or is failing to prosecute or defend vigorously the Third Party Claim. Each Indemnified Party shall obtain the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned, before entering into any settlement of a Third Party Claim. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to enter into or approve any settlement of a Third Party Claim without the consent of the Indemnified Party (which may be withheld in its sole discretion), if the settlement (a) does not expressly unconditionally release all applicable Indemnified Parties and their Affiliates from all Liabilities with respect to such Third Party Claim or (b) imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates, (c) involves any admission of criminal or similar liability, or (d) involves any monetary damages that may not be fully covered by the Indemnifying Party. In the event that the Indemnifying Party fails to assume the defense of the Third Party Claim in accordance with this Section 7.3, (a) the Indemnified Party may defend against the Third Party Claim in any manner it reasonably may deem appropriate, and (b) the Indemnifying Party will remain responsible for any Losses of the Indemnified Party as a result of such Third Party Claim. In circumstances where the Indemnifying Party is controlling the defense of a Third Party Claim in accordance with this Section 7.3, the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose, in which case the fees and expenses of such separate counsel shall be borne by such Indemnified Party. Notwithstanding anything herein to the contrary, in circumstances where there is a conflict of interest that would reasonably make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party, the Indemnified Party shall be entitled to employ separate counsel, that is reasonably acceptable to the Indemnifying Party, and the Indemnifying Party shall pay the reasonable fees and expenses of such separate counsel. Each Party shall cooperate, and cause their respective Affiliates to cooperate in all reasonable respects, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

7.4    Insurance. Each Party shall maintain insurance, including product liability insurance, with respect to its activities under this Agreement regarding Products in such amount as such Party customarily maintains with respect to similar activities for its other products. Each Party shall maintain such insurance for so long as it continues its activities under this Agreement, and thereafter for so long as such Party customarily maintains insurance for itself covering similar activities for its other products. Notwithstanding the foregoing, the Parties agree that during such time that Licensee is an Affiliate of Protiva, Licensee shall have satisfied its obligations under this Section 7.4 provided it is covered by Protiva’s existing insurance policies.

8.1    Term    . The term of this Agreement (the “Term”) shall begin on the Original Effective Date and, unless terminated earlier as provided herein, shall continue in perpetuity.

8.2    Termination for Material Breach    . In the event of a material breach of this Agreement by Licensee, Protiva may provide notice to Licensee setting forth the nature of the breach and a description of the facts underlying the breach sufficient to identify the breach. If Licensee has not cured such breach or proposed a reasonably satisfactory plan to cure or otherwise remedy such breach within ninety (90) days from the date of receipt of such notice of breach, Protiva may provide a notice of termination to Licensee and this Agreement shall terminate ninety (90) days after such notice of termination unless the breach is cured to the reasonable satisfaction of Protiva or unless Licensee has begun to implement a reasonably satisfactory plan to cure or otherwise remedy such breach within ninety (90) days from the receipt of such notice of termination. Notwithstanding the foregoing, or any termination of Licensee’s license pursuant to Section 8.4 below, with respect to any sublicense entered into by Licensee for which the Sublicensee is not the cause of the material breach that resulted in the termination of this Agreement, then upon the assignment to Protiva of all rights of Licensee under such sublicense, Protiva shall assume those obligations of Licensee to such Sublicensee under such sublicense that are within the scope of Protiva’s obligations to Licensee under this Agreement; all other obligations to the Sublicensee under such sublicense, and all liabilities of Licensee to such Sublicensee, shall remain the sole and exclusive obligations and liabilities of Protiva, and nothing in this Section 8.2 shall be deemed to expand, increase, or otherwise modify Protiva’s obligations or liabilities under this Agreement.

8.3    Challenges of Protiva’s Patents. If Licensee or any of its Affiliates shall (a) commence or participate in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise assert in writing any claim, challenging or denying the validity of any of the Protiva Background Patents or Protiva Project Patents or any claim thereof or (b) actively assist any other Person in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity of such Patents or any claim thereof, Protiva will have the right to give notice to Licensee (which notice must be given, if at all, within ninety (90) days after Arbutus’s CEO first learns of the foregoing) that the licenses granted by Protiva to such Patent will terminate in ninety (90) days following such notice, and, unless Licensee and/or its Affiliate, as applicable, withdraws or causes to be withdrawn all such challenge(s) within such ninety-day period, such licenses will so terminate.

8.4    Rights in Bankruptcy. Each Party (the “Insolvent Party”) shall promptly notify the other Party (the “Solvent Party”) in writing upon the initiation of any proceeding in bankruptcy, reorganization, dissolution, liquidation or arrangement for the appointment of a receiver or trustee to take possession of the assets of the Insolvent Party or similar proceeding under the law for release of creditors by or against the Insolvent Party or if the Insolvent Party shall make a general assignment for the benefit of its creditors. To the extent permitted by Applicable Law, if the applicable circumstances described above shall have continued for ninety (90) days undismissed, unstayed, unbonded and undischarged, the Solvent Party may terminate this Agreement upon written notice to the Insolvent Party at any time. If Protiva is the Insolvent Party, the rights and remedies granted

to Licensee (as the Solvent Party) pursuant to this Section 8.4 shall be in addition to, and not in lieu of, Licensee’s rights and remedies under Section 2.4 above.

8.5    Consequences of Termination; Survival.

(a)    In the event this Agreement is properly terminated in accordance with its terms, then except as provided in the Protiva-Monsanto Services Agreement, Licensee’s rights and licenses under the Protiva Intellectual Property shall terminate upon the effective date of such termination. Termination of this Agreement shall not relieve the Parties of any obligation accruing prior to or upon such expiration or termination and the provisions of ARTICLE I – (Definitions), ARTICLE VI – (Confidential Information), ARTICLE VII – (Indemnification), and ARTICLE IX – (Miscellaneous) shall survive any expiration or termination of this Agreement.

(b)    Notwithstanding anything to the contrary contained in this Agreement, if it is determined that Protiva has breached its representation and warranty in Section 9.1(b)(iii), Licensee’s sole and exclusive remedy shall be to require Arbutus or its Affiliate, as applicable, to grant to Licensee a license under its Patents or Know-How for all purposes in the Agricultural Field and such Patents and/or Know-How shall thereafter be included within Protiva Intellectual Property for all purpose of this Agreement; provided, however, that the foregoing shall not be deemed to limit, eliminate or otherwise modify Protiva’s obligations under Section 7.1 to indemnify any Licensee Indemnitee against or hold any Licensee Indemnitee harmless in respect of any Losses actually incurred or suffered by a Licensee Indemnitee arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by UBC or any other Third Party based on any breach of any representation, warranty or covenant by Protiva under this Agreement, including Section 9.1(b)(vi), even if or to the extent such Losses may also arise out Protiva’s breach of Section 9.1(b)(iii). Furthermore, omission from the Technology Transfer Compound List of any Compound or Formulation that was provided or created by Protiva or its Affiliate in connection with the Research Program shall not be deemed to limit or eliminate Licensee’s rights under the second sentence of Section 2.1 with respect to such Compound or Formulation.

8.6    Remedies. The Parties acknowledge and agree that, in the event of a breach or a threatened breach by either Party of this Agreement for which it will have no adequate remedy at law, the other Party may suffer irreparable damage and, accordingly, shall be entitled to injunctive and other equitable remedies to prevent or restrain such breach or threatened breach, in addition to any other remedy they might have at law or at equity. In the event of a breach or threatened breach by a Party of any such provision, the other Party shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which the other Party may be entitled in law or equity.
