(a) Due Organization, Good Standing and Corporate Power. Arbutus is duly organized and validly existing under the Laws of British Columbia and Arbutus is in good standing with the corporate governmental authorities of such jurisdiction with respect to the filing of annual returns and

such other filings as are necessary to maintain its corporate existence and that Arbutus has full corporate power to conduct its business as such business is now being conducted and is duly qualified or licensed to do business in each jurisdiction in which the nature of its business or the ownership or leasing of its properties makes such qualification or licensing necessary, other than in such jurisdictions where the failure to be so qualified or licensed and in good standing would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect.

(b) Authorization. Arbutus has the requisite power and authority to enter into and perform its obligations under the Agreement in accordance with the terms hereof, and the execution and delivery of this Agreement and the performance by Arbutus of its obligations hereunder and the transactions contemplated hereby have been duly authorized by all necessary corporate action of Arbutus and this Agreement has been duly executed and delivered by Arbutus and constitutes a valid and binding obligation of Arbutus, enforceable against Arbutus in accordance with its terms, provided that enforcement thereof may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law).

(c) Noncontravention. The execution and delivery of this Agreement, the consummation of the transactions contemplated by this Agreement will not (i) conflict with any term or provision of the organizational documents or by-laws (or comparable documents) of Arbutus, as amended to the date of this Agreement, (ii) contravene any Securities Laws or any other Laws or Orders applicable to Arbutus that are currently in effect or (iii) conflict in any material respect with, result in a material breach of or default under (with or without notice or lapse of time, or both) give rise to a right of termination, cancellation or acceleration of any obligation or to loss of a benefit under, or result in the creation of any Lien upon any of the properties or assets of Arbutus under, any Contract to which Arbutus is a party or by which Arbutus or any of its assets is bound or subject. The consummation of the transactions contemplated by this Agreement will not result in any impairment on the rights of the Company to use the LNP Assets on the same economic terms as they were used by Arbutus prior to the Closing.

(d) Consents. The execution and delivery of this Agreement and the fulfillment of the transactions contemplated hereby do not, and will not, require the consent, approval, authorization, registration, filing or qualification of or with any Governmental Entity or other third party by Arbutus.

(e) Title and Ownership of Genevant Shares. The Genevant Shares have been duly authorized and validly issued and are fully paid and non-assessable shares of Genevant Canada, and Arbutus owns the Genevant Shares free and clear of any Liens, rights of first refusal or any kind of transfer restrictions other than as required by applicable Securities Laws. No person now has any agreement or option or right or privilege (whether at Law, pre-emptive or contractual) capable of becoming an agreement for the purchase, subscription or issuance of, or conversion into, any unissued shares, securities, warrants or convertible obligations of any nature of Genevant Canada. All of the issued and outstanding capital stock of Genevant Canada is owned directly by Arbutus free and clear of any Liens of any kind.

(f) Title and Ownership. Arbutus has the absolute legal and beneficial ownership of and has good and marketable title to, or in the case of leased assets, a valid leasehold interest in, the LNP Assets (other than all Proprietary Rights included in the LNP Assets, which are owned or licensed by Arbutus as described in Section 4.1(k) of this Agreement), free and clear of all Liens (except for

Permitted Liens). Assuming all required consents of Third Parties set forth on Section 4.1(c)(iii) or Section 4.1(d) of the Disclosure Schedule have been obtained and except for (i) any employees providing services to the LNP Business, other than the Transferred Employees, (ii) the Excluded Assets (including the LNP Propriety Rights, which will be licensed to the Company pursuant to the License Agreement), and (iii) any services made available to the Company and its Affiliates pursuant to the Transition Services Agreement and the Sub-Lease, the sale and transfer of the LNP Assets will constitute a conveyance to the Company, free and clear of all Liens, other than Permitted Liens, of all assets, properties, interests and rights (including real property and tangible and intangible personal property) owned , used or held for use in the conduct of the LNP Business as conducted on the Closing Date.

(g) Licenses. All licenses, registrations, qualifications, permits and consents issued by any Governmental Entity held by Arbutus in connection with the LNP Business that are included in the LNP Assets (collectively, the Licenses) are valid and subsisting and in good standing in all material respects, and Arbutus is in material compliance with all terms of such Licenses and has not received a notice of non-compliance with any such Licenses.

(h) Litigation. There are no actions, suits, proceedings, inquiries or, to Arbutus’ knowledge, investigations existing, or, to Arbutus’ knowledge, pending or threatened against Arbutus or the LNP Business, the LNP Assets or the Assumed Liabilities, at Law or equity, or before or by any court, federal, provincial, state, municipal or other governmental department, commission, board, bureau, agency or instrumentality, domestic or foreign, which, either separately or in the aggregate, have had or would reasonably be expected to have a Material Adverse Effect on the LNP Business, the LNP Assets or the Assumed Liabilities.

(i) Compliance with Laws. Arbutus and its Subsidiaries are not currently conducting and have not, for the past three (3) years, conducted the LNP Business in material violation of any Law or Order applicable to the LNP Business, the LNP Assets or the Assumed Liabilities. In the past three (3) years, neither Arbutus nor any of its Subsidiaries has received any written notice that any violation of the foregoing is being or may be alleged.

(j) LNP Contracts. Neither Arbutus nor any its Subsidiaries, nor, to the knowledge of Arbutus, any other person, is in default in the observance or performance of any material term, covenant or obligation to be performed by Arbutus or any of its Subsidiaries or such other person, as applicable, under any LNP Contract, and all such LNP Contracts are in full force and effect and are legal, valid and binding obligations of Arbutus or one or more of its Subsidiaries and each of the other parties thereto, enforceable in accordance with the terms thereof, except to the extent that its enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law), and no event, circumstance, development, change or effect has occurred which with notice or lapse of time or both would constitute such a default thereunder by Arbutus or any of its Subsidiaries or any other party. Arbutus is not a party to or bound by any non-competition agreement or any other agreement, obligation or Order that purports to (i) limit the manner or the localities in which all or any material portion of the LNP Business is conducted, or (ii) restrict any acquisition or disposition of any of the LNP Assets in any material respect after giving effect to this Agreement.

(k) Intellectual Property.

(i) Section 4.1(k)(i) of the Disclosure Schedule sets forth a true and complete list of all Patents, Trademarks, Copyrights and Licensed IP that are used (or held for use) in the LNP Business and all of the foregoing (as well as any other

Proprietary Rights used (or held for use) in the LNP Business that are not LNP Assets) will, as of the Closing, will be licensed to the Company pursuant to the License Agreement. To Arbutus’ knowledge, all Company IP is valid, enforceable, and subsisting. Arbutus owns and possesses, and the Company will immediately after the Closing Time own and possess (or otherwise have the right to use (or hold for use) or exploit pursuant to the License Agreement) all LNP Proprietary Rights as such LNP Proprietary Rights are used (or held for use) and exploited prior to the Closing Time in the LNP Business, in each case, to the same extent and in the same manner as Arbutus would have had had the transactions contemplated by this Agreement and the Ancillary Agreements not occurred, and without the payment of any additional consideration as a result thereof (except as set forth in the License Agreement), and without the necessity of any Third Party consent as a result thereof.

(ii) Arbutus is the sole legal and beneficial owner of, has good and marketable title to, and exclusively owns and possesses all right, title and interest in and to all the Company IP free and clear of all Liens (except for Permitted Liens). Arbutus has not assigned, licensed or otherwise conveyed any rights or immunities in, to, or under any Proprietary Rights that would otherwise constitute Company IP to any third party.

(iii) Section 4.1(k)(iii) of the Disclosure Schedule contains a true and complete list of all Licensed IP licensed to Arbutus. Arbutus has the right to use and exploit the Licensed IP as such Licensed IP is used in the conduct of the LNP Business as of the Closing Time, and each Contract with respect to the Licensed IP is valid and subsisting and in good standing and there is no default thereunder by Arbutus or, to Arbutus’ knowledge, by any licensor.

(iv) The LNP Proprietary Rights are in full force and effect and have not been used, enforced or not enforced in a manner that would result in their abandonment, cancellation or unenforceability. There is no action, proceeding, investigation, or claim pending or that has been asserted in writing against Arbutus or, to Arbutus’ knowledge, threatened against Arbutus alleging adverse ownership, invalidity or other opposition to, or any conflict with, any of the LNP Proprietary Rights. To Arbutus’ knowledge, Arbutus’ use of the LNP Technology and LNP Proprietary Rights, and the conduct of the LNP Business, as currently conducted, do not and have not infringed, misappropriated, or otherwise violated any Proprietary Rights of any third party.

(v) To Arbutus’ knowledge, Arbutus has not received in the past three (3) years any notice or claim (whether written, oral or otherwise and including invitations to license) challenging Arbutus’ ownership of or right to use or the validity or enforceability of any LNP Proprietary Rights or claiming that any other person has any claim of legal or beneficial ownership or other claim or interest with respect thereto and to Arbutus’ knowledge, there is no reasonable basis for any claim.

(vi) No consent of any person is necessary to make, use, reproduce, license, sell, modify, update, enhance or otherwise exploit any Company IP and none of the Company IP comprises an improvement to any Licensed IP that would give any

person any rights to the Company IP, including, without limitation, rights to license the Company IP.

(vii) Arbutus has used commercially reasonably efforts (including measures to protect secrecy and confidentiality, where appropriate) to protect its trade secrets and other LNP Proprietary Rights and confidential information. Without limiting the generality of the foregoing, to the extent that any of the Company IP is licensed or disclosed to a third party or any third party has access to such the Company IP (including but not limited to any employee, officer, shareholder, consultant, systems-integrator, distributor or other customer of the Company), Arbutus has entered into a valid and enforceable written agreement which contains terms and conditions prohibiting the unauthorized use, disclosure, reverse engineering or transfer of such the Company IP by such third party. All such agreements are in full force and effect and no such third party, to Arbutus’ knowledge, is in default of its obligations thereunder.

(viii) Arbutus is not a party to any options, licenses, agreements, claims, encumbrances or shared ownership interest of any kind relating to LNP Proprietary Rights, nor is Arbutus bound by or a party to any options, leases or agreements of any kind with respect to the Proprietary Rights of any other person.

(ix) To Arbutus’ knowledge, Arbutus has obtained and possess valid licenses to use all of the software programs provided to its employees for their use in connection with the Arbutus Proprietary Rights and present on the computer and other software-enabled electronic devices that it owns or leases or that it has otherwise provided to its employees for their use in connection with Arbutus’ business.

(x) To Arbutus’ knowledge, it will not be necessary to use any inventions of any of its employees or consultants made prior to their employment by Arbutus and there are no inventions of any employees or consultants who are not Transferred Employees that are used in the LNP Business, but which have not been assigned to the Company pursuant to this Agreement.

(xi) To Arbutus’ knowledge, Arbutus has not used any open source, copyleft or community source code in a manner that would require (or purport to require) the distribution or disclosure of the source code of proprietary software of Arbutus.

(xii) The representations and warranties in this Section 4.1(k) are the sole and exclusive representations and warranties of Arbutus concerning Company IP and Licensed IP.

(l) Leased Real Property. The Burnaby Lease is valid and binding and has not been terminated or repudiated by any party thereto. True and complete copies, including all amendments thereto, of the Burnaby Lease have been delivered or made available to Roivant. Arbutus or one of its Subsidiaries has been in peaceable possession since the commencement of the original term of the Burnaby Lease and neither Arbutus nor any of its Subsidiaries is in default thereunder and there exists no default or event, occurrence, condition or act (including the transactions contemplated by this Agreement) in respect of or on the part of Arbutus or any of its Subsidiaries which, with the giving of notice, the lapse of time or the happening of any further event or condition, would become a default or event of default under the Burnaby Lease, other than any such default or event of default which has not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(m) Benefits; Labor.

(i) Except for employment relationships and compensation, benefits, travel advances and employee loans in the ordinary course of business to any officer, director or employee of Arbutus or any of its Subsidiaries, to the knowledge of Arbutus, there is no Contract relating to the LNP Business, the LNP Assets or the Assumed Liabilities between (A) Arbutus or any of its Subsidiaries on the one hand and (B) officer, member, partner or director of Arbutus or any of its Subsidiaries on the other hand.

No person shall be liable for any claim for indemnification under this Article 7 unless a Claim Certificate is delivered by the person (such person, an Indemnified Party) entitled to indemnification pursuant to Section 7.2, Section 7.3 or Section 7.4, as applicable, to the party from which indemnification is sought (the Indemnifying Party) prior to the expiration of the applicable survival period, in which case the representation, warranty, covenant or agreement which is the subject of such claim shall survive to the extent of the claims described in such Claim Certificate until such claim is resolved, whether or not the amount of the Losses resulting from such breach has been finally determined at the time the notice is given.

effect as if made on and as of the Closing Time, except for such representations and warranties which are in respect of a specific date in which case such representations and warranties shall be true and correct as of such date and (b) any Assumed Liability.

(a) None of Arbutus, the Company or Roivant shall be liable for any claim for indemnification made pursuant to Section 7.2, Section 7.3 or Section 7.4, as the case may be, unless the aggregate amount of any Losses incurred that are the subject matter of indemnification equals or exceeds $225,000 (the Basket), in which case Arbutus or Roivant, as the case may be, shall be liable for the aggregate amount of Losses including the amount of the Basket;

(b) in no event shall the total Liabilities of Arbutus under this Agreement for all Losses exceed $3,000,000; and

Notwithstanding anything herein to the contrary, the limitations set forth in this Section 7.5 shall not apply to Losses incurred by Roivant, the Company, Arbutus, or their respective Indemnitees in connection with or arising from (i) any breach of any Roivant Fundamental Representation or Warranty or any Arbutus Fundamental Representation or Warranty, except that the total Liabilities of Roivant or Arbutus for any such breach shall in no event exceed $22,500,000, (ii) the fraud or willful misconduct of Roivant or Arbutus, as applicable, or (iii) Excluded Liabilities or Assumed Liabilities, as applicable.

7.6 Indemnification Procedure

(a) Promptly after the incurrence of any Losses by and Indemnified Party and promptly after an Indemnified Party receives notice of a Third Party Claim which is expected to give rise to indemnification hereunder, the Indemnified Party shall deliver to the Indemnifying Party a certificate (a Claim Certificate), which Claim Certificate shall: (i) state that the Indemnified Party has paid or has incurred Losses for which such Indemnified Party believes it is entitled to indemnification pursuant to this Agreement and (ii) specify in reasonable detail each individual item of Loss included in the amount so stated, the date such item was paid (if paid), the basis for any Loss and the nature of the misrepresentation, breach of warranty, breach of covenant, Assumed Liability, Excluded Liability or claim to which each such item is related and the computation, if possible, of the amount to which such Indemnified Party claims to be entitled hereunder. Such Claim Certificate must be delivered prior to the expiration of the applicable survival period set forth in Section 7.1, in which case the representation, warranty, covenant or agreement which is the subject of such Claim shall survive, to the extent of the Claims described in such notice until such Claim is resolved, whether or not the amount of the Losses resulting from such breach has been finally determined at the time such notice is given.

(b) In the event that the Indemnifying Party does not confirm in writing that it accepts liability for the claim within thirty (30) days of receipt of the Claim Certificate, the Indemnifying Party and the Indemnified Party shall, within the sixty (60) day period beginning on the date of receipt by the Indemnifying Party of such Claim Certificate and prior to submitting such dispute to the courts set forth in Section 9.5, attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims to which the Indemnifying Party shall have so objected. If the Indemnified Party and the Indemnifying Party shall succeed in reaching agreement on their respective rights with respect to any

of such claims, the Indemnified Party and the Indemnifying Party shall promptly prepare and sign a memorandum of agreement setting forth such agreement. Should the Indemnified Party and the Indemnifying Party be unable to agree as to any particular item or items or amount or amounts within such time period, then the Indemnified Party shall be permitted to submit such dispute to the courts set forth in Section 9.5. The party that receives a final judgment in such dispute shall reimburse the other party for all reasonable attorney and consultant fees or expenses incurred by the other party.

(c) Claims for Losses covered by a memorandum of agreement of the nature described in Section 7.6(b), and claims for Losses the validity and amount of which have been the subject of judicial determination as described in Section 7.6(b) and 10.6 or shall have been settled as described in Section 7.7, are hereinafter referred to, collectively, as “Agreed Claims”. Within ten (10) Business Days of the determination of the amount of any Agreed Claim (or at such other time as the Indemnified Party and the Indemnifying Party shall agree), the Indemnifying Party shall pay to the Indemnified Party an amount equal to the Agreed Claim by wire transfer in immediately available funds to the bank account or accounts designated by the Indemnified Party in a notice to the Indemnifying Party not less than two (2) Business Days prior to such payment.

7.7 Third Party Claims

(a) If a claim by a third party is made against any Indemnified Party (a Third Party Claim), and if such party intends to seek indemnity with respect thereto under this Article 7, such Indemnified Party shall promptly notify the Indemnifying Party of such Third Party Claim; provided, that the failure to so notify shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent that the Indemnifying Party is materially prejudiced thereby. The Indemnifying Party shall have thirty (30) days after receipt of such notice to assume the conduct and control, through counsel reasonably acceptable to the Indemnified Party at the expense of the Indemnifying Party, of the settlement or defense of such Third Party Claim; provided, that (i) the Indemnifying Party shall permit the Indemnified Party to participate in such settlement or defense through counsel chosen by such Indemnified Party; provided, that the fees and expenses of such counsel shall be borne by such Indemnified Party; provided, further, that the Indemnifying Party shall not be entitled to assume control of such defense and shall pay the fees and expenses of counsel retained by the Indemnified Party if (A) such Third Party Claim for indemnification relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation; (B) such Third Party Claim seeks an injunction or equitable relief against the Indemnified Party and does not otherwise seek monetary damages; (C) the Indemnified Party has been advised in writing by counsel that there is an actual conflict of interest between the Indemnifying Party and the Indemnified Party; or (D) upon petition by the Indemnified Party, the appropriate court rules that the Indemnifying Party failed or is failing to vigorously prosecute or defend such Third Party Claim.

(b) Any Indemnified Party shall have the right to employ separate counsel in any such action or claim and to participate in the defense of such Third Party Claim, but the fees and expenses of such counsel shall not be at the expense of the Indemnifying Party unless (i) the Indemnifying Party shall have failed, or is not entitled, to assume the defense of such Third Party Claim in accordance with Section 7.7(a), or (ii) the named parties to any such action (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party and such Indemnified Party shall have been advised in writing by such counsel that there may be one (1) or more legal defenses available to the Indemnified Party which are not available to the Indemnifying Party, or available to the Indemnifying Party the assertion of which would be adverse to the interests of the Indemnified Party. The Indemnified Party shall not pay or settle any such Third Party Claim without the prior written consent of the Indemnifying Party, not to be unreasonably withheld. Notwithstanding the foregoing, the Indemnified Party shall have the right to pay or settle any such Third Party Claim; provided, that in such event it shall waive any right

to indemnity therefor by the Indemnifying Party for such Third Party Claim, and the related settlement payments or other actions taken in settlement shall not constitute “Losses” under this Agreement.

(c) If the Indemnifying Party does not notify the Indemnified Party within thirty (30) days after the receipt of the Indemnified Party’s notice of a Third Party Claim of indemnity hereunder that it elects to undertake the defense thereof, the Indemnified Party shall have the right to contest, settle or compromise the Third Party Claim but shall not thereby waive any right to indemnity therefor pursuant to this Agreement.

(d) The Indemnifying Party shall not, except with the consent of the Indemnified Party, not to be unreasonably withheld, enter into any settlement unless such settlement (i) is entirely indemnifiable by the Indemnifying Party pursuant to this Article 7, (ii) includes as an unconditional term thereof the giving by the person or persons asserting such Third Party Claim to all Indemnified Parties of an unconditional release from all Liabilities with respect to such Third Party Claim or consent to entry of any judgment and (iii) does not impose any injunctive relief or other restrictions of any kind or nature on any Indemnified Party.

(e) The Indemnifying Party and the Indemnified Party shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available records relating to such Third Party Claim and furnishing, without expense to the Indemnifying Party and/or its counsel, such employees of the Indemnified Party as may be reasonably necessary for the preparation of the defense of any such Third Party Claim or for testimony as witnesses in any proceeding relating to such Third Party Claim.

7.8 Losses Net of Insurance and Taxes

The amount of any Loss for which indemnification is provided under Section 7.2, Section 7.3 or Section 7.4 shall be net of (a) any amounts recovered by the Indemnified Party (net of any costs of investigation of the underlying claim and of collection) pursuant to any indemnification by or indemnification agreement with any person (other than this Agreement), and (b) any insurance proceeds (net of any costs of investigation of the underlying claim and of collection) received as an offset against such Loss (each such source of recovery, a Collateral Source). If the amount to be netted hereunder in connection with a Collateral Source from any payment required under Section 7.2, Section 7.3 or Section 7.4 is received after payment by the Indemnifying Party of any amount otherwise required to be paid to an Indemnified Party pursuant to this Article 7, the Indemnified Party shall repay to the Indemnifying Party, promptly after such receipt, any amount that the Indemnifying Party would not have had to pay pursuant to this Article 7 had such receipt occurred at the time of such payment. Each Indemnified Party shall take commercially reasonable steps to mitigate any Losses as soon as reasonably practicable after such Indemnified Party becomes aware of any event which does, or could reasonably be expected to, give rise to any such Losses. For all purposes of this Article 7, “Losses” shall be reduced by any Tax benefit actually realized in cash Tax savings by the Indemnified Party or its Affiliates arising as a result of the accrual, incurrence or payment of any such Losses in or prior to the taxable year in which the indemnity payment is made and the Indemnified Party shall pay the Indemnifying Party the amount of any Tax Benefit actually realized by the Indemnified Party or its affiliates in the two taxable years after the year in which the indemnity payment is made, net of any reasonable costs relating to obtaining such Tax benefit. Each Indemnified Party shall use commercially reasonable efforts to collect the proceeds of any insurance or any obligation of any third party which would have the effect of reducing any Losses.

7.9 Sole Remedy/Waiver

Except in the case of fraud, the Parties acknowledge and agree that, in the event that the Closing occurs, the remedies provided for in this Article 7 shall be the Parties’ sole and exclusive

remedies for: (a) any breach of the representations and warranties made on or prior to the Closing in this Agreement, the Disclosure Schedule, the Xxxx of Sale and Assignment and Assumption Agreement, the License Agreement, any other Ancillary Agreement (other than the Shareholders Agreement) and all other certificates delivered pursuant to this Agreement or (b) any breach of any covenant contained in, or any claims relating to, this Agreement, the Disclosure Schedule, the Xxxx of Sale and Assignment and Assumption Agreement, and all other certificates delivered pursuant to this Agreement, the Company or any Law or otherwise. The Parties expressly intend that the remedies provided for in this Article 7 shall apply to direct claims between the Parties for breach of this Agreement (whether or not involving a third party).

7.10 Indemnification by Share Surrender

(a) Notwithstanding anything herein to the contrary, Arbutus may, at its election, satisfy and pay any or all indemnification obligations under Section 7.2(a) or Section 7.2(b) by surrendering to the Indemnified Party Common Shares of the Company in a number necessary to satisfy such obligations, with the surrendered shares valued at the Fair Market Value thereof as of the date of delivery of a Claim Certificate.

(b) As used in this Agreement, Fair Market Value of Common Shares means: the cash price that an unaffiliated third party would pay to acquire all of such Common Shares (computed on a fully diluted basis) assuming that the Company was being sold in a manner reasonably designed to solicit all possible participants and permit all interested Persons an opportunity to participate and to achieve the best value reasonably available to the stockholders of the Company at the time, taking into account all then-existing circumstances, (x) as mutually agreed by Roivant and Arbutus or (y) if Roivant and Arbutus do not mutually agree, as determined in accordance with clause (c) below.

(c) In the event that Arbutus and Roivant do not mutually agree upon the Fair Market Value of the Common Shares within 15 days of Arbutus notifying Roivant that it has elected to pay an indemnity claim with Common Shares pursuant to Section 7.10(a), each of Arbutus and Roivant covenants and agrees to take all actions reasonably necessary to determine the Fair Market Value, including the following:

(i) Within 30 days of Arbutus notifying Roivant that it has elected to pay an indemnity claim with Common Shares pursuant to Section 7.10(a), Arbutus and Roivant shall jointly designate a mutually agreed investment banking firm of international repute which is neither an Affiliate of any party nor has performed any significant work for any party or any Affiliate of any party within the prior two (2) years (the Mutually Agreed Appraiser) to determine the Fair Market Value. If the parties are unable to mutually agree upon the Mutually Agreed Appraiser, then it shall be selected by an arbitrator constituted and acting under the International Arbitration Rules then in effect of the International Centre for Dispute Resolution (ICDR) of the American Arbitration Association (the Rules), and such arbitrator shall be selected and appointed in accordance with the Rules.

(ii) The Company shall provide the Mutually Agreed Appraiser with reasonable access to members of management of the Company and to the books and records of the Company so as to allow Mutually Agreed Appraiser to conduct due diligence examinations in scope and duration as are customary in valuations of this kind. Arbutus, Roivant and the Company each agree to cooperate with the Mutually Agreed Appraiser and to provide such information as may reasonably

be requested by the Mutually Agreed Appraiser. Costs of the appraisals shall be borne equally by Arbutus and Roivant.

(b) The Parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Agreement must be brought exclusively in a federal district court or a state court in New York County, New York. Each of the parties hereto hereby consents and submits to the exclusive jurisdiction of such courts. No legal action, suit or proceeding with respect to this Agreement may be brought in any other forum except to enforce a judgment entered in a court described in the preceding sentence. Each Party irrevocably waives all claims of immunity from jurisdiction and any right to object on the basis that any dispute, action, suit or proceeding brought in such court has been brought in an improper or inconvenient forum or venue.

(c) Each Party hereby agrees that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.3, or in such other manner as may be permitted by applicable Law, shall be valid and sufficient service thereof and hereby waives any objections to service accomplish in the manner herein provided.

Accordingly, it is acknowledged that the Parties shall be entitled to equitable relief, without proof of actual damages, including an injunction or injunctions or orders for specific performance to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in addition to any other remedy to which they are entitled at law or in equity as a remedy for any such breach or threatened breach.
