2.4Option to License Capsid Candidates for Development and Commercialization of Licensed Products.

2.4.1Voyager hereby grants to Pfizer an option to receive the license as set forth in Section 3.1.2 for up to two (2) Pfizer Transgenes (each, an “Option”). Pfizer may exercise the Option at any time prior to the first (1^st) anniversary of the Effective Date (the “Option Period”) by providing written notice to Voyager, in accordance with Section 11.7, identifying, for each Pfizer Transgene for which an Option is exercised, the specific Capsid Candidate that will become a Licensed Capsid for such Pfizer Transgene (an “Option Exercise Notice”). Pfizer may exercise each of its Options on the same or different Capsid Candidates for each Pfizer Transgene during the Research Term, but may only exercise one Option per Pfizer Transgene. Upon Voyager’s receipt of each Option Exercise Notice (the “Option Exercise Date”) each Capsid Candidate identified in the corresponding Option Exercise Notice will be deemed a “Licensed Capsid” for the selected Pfizer Transgene. Promptly following receipt of Pfizer’s Option Exercise Notice, Voyager will issue the appropriate invoice in accordance with Section 5.3.3 and provide Pfizer with any Voyager Know-How for the corresponding Licensed Capsid that has not been previously provided to Pfizer as may be reasonably necessary or that the Parties mutually agree may be useful to enable Pfizer to Exploit such Licensed Capsid for use in Licensed Products containing such Pfizer Transgene; provided that Voyager shall not provide Pfizer with any Know-How that is not reasonably necessary for Exploiting a Licensed Capsid without Pfizer’s prior written consent.  In the event Voyager provides Know-How that is not reasonably necessary for Exploiting a Licensed

​

A-14

​

Capsid without Pfizer’s prior written consent, then Pfizer shall have the right to use such Know-How for all research, development, and regulatory purposes, without accountability to Voyager.

2.4.2All Option exercise notices delivered by Pfizer shall specify whether the exercise of the applicable Option, in Pfizer’s good faith assessment based on advice from specialized counsel, requires filings under the Hart-Scott-Rodino Antitrust Improvement Act (as amended from time to time, the “HSR Act”) or similar antitrust or competition laws of other jurisdictions (collectively, the “Antitrust Filings”).  If Pfizer concludes that Antitrust Filings are required, then: (a) the Parties will (i) use reasonable efforts to make the requisite filings as promptly as possible, and in the case of filings under the HSR Act in any event no later than [**] after the exercise notice for the applicable Option, and (ii) collaborate with each other in taking appropriate steps to achieve expiration or termination of all applicable waiting periods as promptly as possible; and (b) the effectiveness of the relevant license(s) set forth in Section 3.1.2 shall be conditioned upon expiration or termination of such applicable waiting periods.

2.5Capsid Substitution. After exercise of any Option but during the Research Term, Pfizer may conduct additional Evaluation of the TRACER Capsid Candidates, and may elect to substitute any TRACER Capsid Candidate for any Licensed Capsid by providing written notice to Voyager, in accordance with Section 11.7, identifying the TRACER Capsid Candidate (the “Substitute Capsid”) and the specific Pfizer Transgene for which the Substitute Capsid will replace the previously designated Licensed Capsid. Immediately following Pfizer’s exercise of such substitution notice, the Substitute Capsid will replace the previous Licensed Capsid for such Pfizer Transgene, and Voyager will provide Pfizer with any Voyager Know-How for the Substitute Capsid that has not been previously provided to Pfizer as may be reasonably necessary or that the Parties mutually agree may be useful to enable Pfizer to Exploit such Substitute Capsid for use in Licensed Products containing such Pfizer Transgene.

ARTICLE 4

DEVELOPMENT, REGULATORY AND COMMERCIALIZATION ACTIVITIES

4.1Pfizer Authority and Obligations.

4.1.1As of each applicable Option Exercise Date, Pfizer will be solely responsible for, and have sole decision-making authority with respect to, at its own expense, the Exploitation of Licensed Products and Licensed Capsids as they are used to Exploit a Licensed Product. During the Term, Voyager will be responsible for maintaining any third-party agreement it has entered as of the Effective Date (if any) that is required for Pfizer to practice the rights granted by Voyager to Pfizer in the Agreement, including payment by Voyager of any amounts due under such third-party agreements.

4.1.2Diligence.

(a)Development Diligence. Pfizer will use Commercially Reasonable Efforts to Develop and obtain Regulatory Approval for at least one (1) Licensed Product for each Pfizer Transgene for which Pfizer has exercised its Option in the United States and at least one Major Market Country. Pfizer will have no other diligence obligations with respect to the Development or Regulatory Approval of Products under this Agreement.

​

A-17

​

(b)Commercial Diligence. Pfizer will use its Commercially Reasonable Efforts to Commercialize each Licensed Product in the United States and at least one Major Market Country in the Territory where Pfizer or its designated Affiliates or Sublicensee has received Regulatory Approval for such Licensed Product. Pfizer will have no other diligence obligations with respect to the Commercialization of Products under this Agreement.

(c)Exceptions to Diligence Obligations. Notwithstanding any provision of this Agreement to the contrary, Pfizer will be relieved of its diligence obligations under this Agreement with respect to any Licensed Product to the extent that any of the following occurs with respect to such Licensed Product:

(i)Pfizer or Voyager receives, generates, or otherwise becomes aware of, any safety, tolerability, or other data reasonably indicating or signaling that a Licensed Capsid or Licensed Product has or would have an unacceptable risk-benefit profile or is otherwise not reasonably suitable for initiation or continuation of Clinical Trials; or

(ii)Pfizer or Voyager receive any notice, information or correspondence from any applicable Regulatory Authority, or any applicable Regulatory Authority takes any action, that reasonably indicates that a Licensed Product is unlikely to receive Regulatory Approval.

(d)Deemed Satisfaction of Pfizer’s Diligence Obligations. Without in any way expanding Pfizer’s obligations under this Agreement:

(i)Pfizer’s achievement of any Development Milestone Event entitling Voyager to receive a specific Development Milestone Payment described in Section 5.3.2 will be conclusive evidence that Pfizer has satisfied all of its diligence obligations under this Agreement for the corresponding Licensed Product, up to the date that such Development Milestone Event is achieved;

(ii)Pfizer’s payment, and Voyager’s acceptance, of any royalties to Voyager pursuant to Section 5.4.1 will be conclusive evidence that Pfizer has satisfied all of its diligence obligations under this Agreement for the corresponding Licensed Product to the date of such payment; provided that if Voyager does not return in full a payment of royalties by Pfizer with a written rejection of such payment within [**] of receipt, Voyager shall be deemed to have accepted such royalty payment; and

(iii)Pfizer’s payment of any Sales Milestone Payment as set forth in Section 5.3.4 will be conclusive evidence that Pfizer has satisfied all its diligence obligations under this Agreement for the corresponding Licensed Product to the date of such payment.

(e)For the avoidance of doubt, the provisions of Section 4.1.2(d) are intended only as examples of diligence constituting satisfaction of Pfizer’s diligence obligations. Pfizer may fully satisfy its diligence obligations without achieving any of the specific diligence examples set forth in Section 4.1.2(d), provided that Pfizer otherwise complies with the provisions of Section 4.1.2(a) or Section 4.1.2(b), as applicable.

​

A-18

​

(f)Assertion of Pfizer Diligence Obligation Claims. If Voyager is, becomes, or reasonably should be aware of facts that might form a reasonable basis to allege that Pfizer has failed to meet any of its diligence obligations, then Voyager will promptly notify Pfizer in writing of such potential alleged performance failure (each such potential alleged performance failure, a “Diligence Issue”). Promptly upon Pfizer’s receipt of any notice of a Diligence Issue pursuant to this Section 4.1.2(f), the Pfizer Alliance Manager will contact the Voyager Alliance Manager to discuss the specific nature of such Diligence Issue and seek to identify an appropriate corrective course of action. If, no later than [**] after Pfizer’s receipt of such a notice, (i) the Parties have not reached consensus regarding whether Pfizer has failed to satisfy its obligations pursuant to Section 4.1.2(a) or Section 4.1.2(b) and (ii) the Parties’ respective Alliance Managers have not agreed upon an appropriate corrective course of action for such Diligence Issue, then such Diligence Issue will be escalated and resolved pursuant to the dispute resolution provisions set forth in Section 11.2. If Voyager fails to notify Pfizer of a Diligence Issue pursuant to this Section 4.1.2(f) within [**] after the date that Voyager first discovers or reasonably should have discovered such Diligence Issue, then Pfizer will be deemed to have satisfied its obligations under Section 4.1.2(a) and Section 4.1.2(b) with respect to such Diligence Issue.

4.1.3Remedies for Breach of Pfizer Diligence Obligations. If Pfizer materially breaches any of its diligence obligations under Section 4.1.2 and Pfizer fails to remedy such breach within [**] after Pfizer’s receipt of notice of such breach from Voyager, then Voyager may, in its sole discretion, elect to either: (i) terminate this Agreement pursuant to the provisions of Section 10.3.1 on a Licensed Product-by-Licensed Product and country-by-country basis; or (ii) convert any exclusive license or sublicense granted to Pfizer under this Agreement into a non-exclusive license, solely in each case of (i) and (ii) with respect to a Licensed Product in the country that is the subject of the material breach.

4.1.4Reporting. Following the exercise of each Option and prior to the First Commercial Sale of the corresponding Licensed Product in each of the jurisdictions where any of the milestone payments under Section 5.3 remain outstanding, for each Licensed Product, Pfizer will provide to Voyager a confidential [**] written report summarizing the material Development, Manufacture and Commercialization activities it has undertaken in such jurisdiction(s) during the preceding [**] period and the material Development, Manufacture and Commercialization activities it expects to take in the following [**] period, including any milestones expected to be achieved.

4.1.5Cooperation. Upon Pfizer’s request and at Pfizer’s expense, Voyager will provide Pfizer with reasonable assistance in connection with Pfizer’s preparation of any portion(s) of the relevant Regulatory Filings that relate to the Licensed Products, including by providing relevant data in Voyager’s possession and participating in meetings between the Parties to prepare documents to be filed.

4.2Remedy for Pfizer Deprioritizing a Licensed Capsid.  Without limiting Pfizer’s obligations under Section 4.1.2, on a Licensed Product-by-Licensed Product basis, if, during the period beginning on the corresponding Option Exercise Date for a Pfizer Transgene and ending on the date Pfizer first Commercializes the corresponding Licensed Product in the United States and one Major Market Country, (i) Pfizer declares a lead candidate incorporating a Pfizer Transgene for Development, and (ii) Pfizer does not include a lead candidate or a back-up candidate

​

A-19

​

incorporating a Licensed Capsid and a Pfizer Transgene in its Development efforts for any contiguous [**] period, as indicated in Pfizer’s [**] report made under Section 4.1.4 and provided that such lack of inclusion is not a result of a matter set forth in Section 4.1.2(c)(i), then, within [**] after receiving such report, Voyager shall notify Pfizer in accordance with Section 11.7 of any objection it has to such lack of inclusion.  If Voyager timely notifies Pfizer of its objection and Pfizer does not include a lead candidate or back-up candidate that incorporates the corresponding Licensed Candidate and Pfizer Transgene within [**] after Pfizer’s receipt of such notice, then Voyager may, in its sole discretion, immediately elect to convert the corresponding exclusive license or sublicense granted to Pfizer under this Agreement into a non-exclusive license, with (a) all subsequent development obligations under Section 4.1.2 terminating for the corresponding Licensed Product and (b) all amounts for the corresponding Licensed Product that would be due hereunder after Voyager elects such non-exclusive license being reduced by [**] percent ([**]%).

5.3Milestone Payments.

5.3.1Generally. Pfizer will provide Voyager with written notice (a “Development Milestone Event Notice”) of the achievement of a development milestone event specified in Section 5.3.2 for the first Licensed Product, per Pfizer Transgene, to achieve such milestone event (each, a “Development Milestone Event”). Such notice will be provided within [**] after such Development Milestone Event is achieved; provided that in the case such Development Milestone Event is achieved by a Sublicensee, Pfizer’s notice shall be provided within [**] after Pfizer receives notice from the corresponding Sublicensee of achieving the Development Milestone Event.

​

A-20

5.3.2 Development Milestone Events and Payments. Notwithstanding anything to the contrary in this Agreement, this Section 5.3.2 shall apply only if Pfizer exercises the corresponding Option. Pfizer will pay Voyager the amounts set forth below within [**] following the first occurrence of each event described below for the first Licensed Product for each Pfizer Transgene to achieve such Development Milestone Event (each, a “Development Milestone Payment”). If for any reason Development Milestone Event (a) below does not occur prior to the occurrence of Development Milestone Event (b) below, then Development Milestone Event (a) will be deemed to occur concurrently with the occurrence of Development Milestone Event (b), and the Development Milestone Payments associated with both Development Milestone Events will be paid following the achievement of Development Milestone Event (b).

​

Each of the Development Milestone Payments set forth above will be payable one time only per Pfizer Transgene incorporated into a Licensed Product (regardless of the number of Licensed Products with the same Pfizer Transgene, or the number of times with respect to any Licensed Product with the same Pfizer Transgene, achieves the specified Development Event occurs). No Development Milestone Payments will be payable by Pfizer for any subsequent Licensed Product for a Pfizer Transgene regardless of the number of Licensed Products for such Pfizer Transgene are Developed. For clarification, if one Licensed Product replaces another Licensed Product in Development, then such replacement Licensed Product will only be subject to Development Milestone Payments that have not previously been triggered by one or more prior Licensed Products for the corresponding Pfizer Transgene. The maximum amount payable by Pfizer under this Agreement with respect to all Development Milestone Payments if all Development Milestone Events occur will be $230,000,000.

5.3.3Invoicing and Payment Procedure. All fees owed to Voyager will be payable within [**] after Pfizer’s receipt of an invoice from Voyager, including an appropriate Pfizer Purchase Order (PO) number, reference to this Agreement, amount owed and name and address payment is to be sent to. All invoices will be delivered to Pfizer by email to [**] with a copy to [**] and [**].  All invoice or billing related questions should be referred to Pfizer's Accounting Department at [**] or go to the Accounts Payable Inquiry Tool (APIQ) at www.pfizeraccountspayable.com.

Subject to the adjustments under Section 5.5, Pfizer will make tiered royalty payments to Voyager in respect of Annual Net Sales, on a Licensed Product-by-Licensed Product basis, by Pfizer, its Affiliates or Sublicensees at the following royalty rates during the applicable Royalty Term:

​

5.4.2Calculation of Royalties. Royalties on aggregate Annual Net Sales of Licensed Products in a Calendar Year during the Royalty Term will be paid at the rate applicable to the portion of Net Sales within each of the Annual Net Sales tiers during such Calendar Year. For example, if, during a Calendar Year during the Royalty Term, Annual Net Sales of all Licensed Products are equal to $[**], then the royalties payable by Pfizer would be calculated by [**].

​

A-22

5.5Royalty Adjustments.

5.5.1Valid Claim Expiration. If, during any Calendar Quarter during the Royalty Term, on a country-by-country and Licensed Product-by-Licensed Product basis, there is no Valid Claim within the Licensed Capsid Patents that Covers such Licensed Product in such country, then the royalty rate for such Licensed Product in such country will be reduced by [**] percent ([**]%) from the applicable rate(s) set forth in Section 5.4.1.

5.5.2Third Party Licenses. In the event that, during the Royalty Term on a Licensed Product-by-Licensed Product basis, Pfizer, its Affiliates or Sublicensees are required to pay royalties to a Third Party in consideration for a license under Patents Controlled by such Third Party that are reasonably necessary for Exploiting a Licensed Capsid as part of a Licensed Product (“Third Party License ”), then Pfizer may deduct [**] percent ([**]%) of the royalties payable to such Third Party for such Third Party License(s) from royalties owed by Pfizer to Voyager under Section 5.4.1 for Net Sales of the applicable Licensed Product(s), with such reduction continuing until all such amounts have been expended for such Calendar Quarter; provided that royalties to a Third Party in consideration for a license under Patents Controlled by a Third Party that are reasonably necessary for Exploiting the Pfizer Transgene or other component of a Licensed Product shall not be deductible against the royalties owed by Pfizer to Voyager hereunder.

5.5.3Biosimilar Products. For any Pfizer Quarter in the applicable Royalty Term for a Licensed Product in a country in the Territory during which (1) a Biosimilar Product with respect to such Product is being sold in such country; and (2) the unit volume of such Biosimilar Product sold in such country in such Pfizer Quarter exceeds [**] percent ([**]%) of the combined unit volume of such Product and such Biosimilar Product sold in such country in such Pfizer Quarter, subject to Section 5.5.4, the royalties payable on Net Sales of such Product in such country in such Pfizer Quarter would be reduced by [**] percent ([**]%) of the amounts of royalties otherwise payable on such Net Sales pursuant to Section 5.4.1 for the remainder of the applicable Royalty Term, such reduction to be prorated appropriately in aggregate for the then-current Pfizer Quarter. The unit volume of the Licensed Product and Biosimilar Product shall be calculated using a mutually acceptable method and using market share data provided by a reputable and mutually agreed upon provider.

5.5.4Limit on Deductions.

(a)On a Licensed Product-by-Licensed Product basis, in no event will the cumulative effect of the adjustments in Sections 5.5.1 through Section 5.5.3 reduce the royalties payable to Voyager under Section 5.4.1 by more than [**] percent ([**]%) of the amounts that would otherwise have been payable with respect to the applicable Licensed Product in the applicable country in the applicable Calendar Quarter (the “Royalty Floor”). In the event that a reduction would be permitted under this Section 5.5 but for the fact that such reduction would reduce the applicable royalties payable in accordance with Section 5.4.1 by more than the Royalty Floor. Pfizer may carry over such royalty reduction to payments payable hereunder with respect to any royalty payments owed in any future Calendar Quarter, in each case on a with such reduction continuing until all such amounts have been expended.

5.6Reports; Payment of Royalty. Within [**] after the end of each Calendar Quarter, Pfizer will deliver to Voyager a report setting forth, for the most recent Pfizer Quarter ending during such Calendar Quarter, the following information, on a Licensed Product-by-Licensed

Product, country-by-country and Territory-wide basis: (a) Net Sales of each Licensed Product; (b) the basis for any adjustments to the royalty payable for the sale of any such Licensed Product; and (c) the royalty due hereunder for the sale of each such Licensed Product. No such reports will be due for any such Licensed Product: (x) before the First Commercial Sale of such Product; or (y) after the Royalty Term for such Licensed Product has expired in all countries in the Territory. The total royalty due for the sale of all such Licensed Products during such Pfizer Quarter will be remitted at the time such report is made; provided that to the extent any royalties are payable by Pfizer hereunder on Net Sales of a Product in a country solely due to a Valid Claim of a Licensed Capsid Patent Covering such Licensed Product in such country that is subject to a revocation, invalidity or unenforceability ruling that is appealable or being appealed, during the time of such appeal or appealability, [**] percent ([**]%) of such royalties payable by Pfizer shall be placed into an escrow account and either (I) returned to Pfizer upon a final, unappealable determination that such revocation, invalidity or unenforceability ruling is upheld in a final, unappealable determination or (II) released to Voyager in the event such revocation, invalidity or unenforceability ruling is not upheld in a final, unappealable determination.

5.7Accounting; Audit.

5.7.1Records.

9.2.1the gross negligence, recklessness or wrongful intentional acts or omissions of Voyager or any of its Affiliates or subcontractors, or its or their respective directors, officers, employees, agents, consultants or Representatives, in connection with performance by or on behalf of Voyager or exercise of Voyager’s rights under this Agreement; or

except, in each case, to the extent such Losses arise from (x) the negligence, recklessness, or intentional acts of any Pfizer Indemnified Party or (y) any Third Party Claim for which Pfizer is responsible for indemnifying Voyager pursuant to Section 9.1.

9.3Notice. Each Party will notify the other Party in writing in the event it becomes aware of a claim for which indemnification may be sought hereunder. In the event that any Third Party asserts a Claim or other proceeding (including any governmental investigation) with respect to any Third Party Claim for which a Party (the “Indemnified Party”) is entitled to indemnification hereunder, then the Indemnified Party shall promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

9.4Control. Subject to each Party’s right to control certain actions described in Sections 6.3 and 6.4 (even where such Party is the Indemnifying Party), the Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within [**] after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal, or other disposition of the Third Party Claim (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party; provided that (a) the Indemnifying Party has sufficient financial resources, in the reasonable judgment of the Indemnified Party, to satisfy the amount of any adverse monetary judgment that is sought, (b) the Third Party Claim seeks solely monetary damages, and (c) the Indemnifying Party expressly agrees in writing that as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated to satisfy and discharge the Third Party Claim in full (the conditions set forth in clauses (a), (b), and (c) above are collectively referred to as the “Litigation Conditions”).

If the Indemnified Party reasonably so objects, the Indemnified Party shall continue to defend the Third Party Claim, at the expense of the Indemnifying Party, until such time as such objection is withdrawn. If no such notice is given, or if any such objection is withdrawn, the Indemnifying Party shall be entitled, at its sole cost and expense, to assume direction and control of such defense, with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. During such time as the Indemnifying Party is controlling the defense of such

​

A-38

​

Third Party Claim, the Indemnified Party shall cooperate, and shall cause its Affiliates and agents to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information, and testimony and attending such conferences, discovery proceedings, hearings, trials, or appeals as may reasonably be requested by the Indemnifying Party. In the event that the Indemnifying Party does not satisfy the Litigation Conditions or does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within [**] after notice thereof, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to join in (including the right to conduct discovery, interview, and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

9.5Settlement. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party (not to be unreasonably withheld, conditioned or delayed), enter into any compromise or settlement that commits the Indemnified Party to take, or to forbear to take, any action (other than the payment of money which will be fully satisfied by the Indemnifying Party). The Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief, but shall not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages for which the Indemnifying Party would be responsible without the prior written consent of the Indemnifying Party (not to be unreasonably withheld). Each of the Indemnifying Party and the Indemnified Party shall not make any admission of liability in respect of any Third Party Claim without the prior written consent of the other Party, and the Indemnified Party shall use reasonable efforts to mitigate Liabilities arising from such Third Party Claim.

9.6Insurance. Each Party agrees to obtain and maintain, during the Term, commercial general liability insurance, including products liability insurance (or clinical trials insurance, if applicable), with minimum “A-” A.M. Best rated insurance carriers to cover its indemnification obligations under Section 9.1 or Section 9.2, as applicable, in each case with limits of not less than $[**] U.S. dollars) per occurrence and in the aggregate. All deductibles and retentions will be the responsibility of the named insured. Pfizer and its Affiliates will be an additional insured on Voyager’s commercial general liability and products liability policies (or clinical trials insurance, if applicable), and be provided with a waiver of subrogation. For U.S. exposures, additional insured status on Voyager’s commercial general liability and products liability policies shall be via form CG20101185 or its equivalent. Licensed Products liability coverage shall be maintained for [**] following termination of this Agreement. To the extent of its culpability or negligence, all coverages of Voyager will be primary and non-contributing with any similar insurance, carried by Pfizer. Notwithstanding any provision of this Section 9.6 to the contrary, Pfizer may meet its obligations under this Section 9.6 through any combination of insurance and self-insurance. Neither Party’s insurance will be construed to create a limit of liability with respect to its indemnification obligations under this Article 9. Each Party will furnish the other Party with a certificate of such insurance promptly following request.

(b)Termination for Cause by Voyager; Termination for Convenience by Pfizer After the Option Exercise Date. On a Licensed Product-by-Licensed Product basis, in the event that, following the Option Exercise Date, Voyager terminates this Agreement for cause pursuant to Section 10.3.1 or Pfizer terminates this Agreement for convenience pursuant to Section 10.5, except as otherwise expressly provided herein, all rights and obligations of each Party hereunder that correspond with such termination will cease (including all rights and licenses and sublicenses granted by either Party to the other Party hereunder corresponding to the terminated Licensed Product(s)); provided that Pfizer will have the right, in its sole discretion, to sell any inventory of any Licensed Product affected by such termination that remains on hand as of the effective date of the termination, so long as Pfizer pays to Voyager the royalties and other amounts payable hereunder (including milestones) that are applicable to such subsequent sales in the applicable Territory in accordance with the terms of this Agreement.

(c)Termination for Cause by Pfizer.

(i)Partial Termination. In the event that, on or following the Option Exercise Date, (a) Pfizer terminates this Agreement pursuant to Section 10.3.2 or 10.3.3 with respect to a Licensed Product in any country in the Territory, and the event that gave rise to the right of termination materially impairs the ability to Exploit the applicable Licensed Product in the applicable terminated country, then (b) all licenses granted to Pfizer under this Agreement with respect to such Licensed Product in such country will become irrevocable and perpetual, and Pfizer will have no further obligations to Voyager under this Agreement with respect to such Licensed Product in such country, other than (i) those obligations that expressly survive termination in accordance with Section 10.7.3, (ii) an obligation to pay all milestones and royalties under Sections 5.3 and 5.4 with respect to such Licensed Products in such terminated country in an amount equal to [**] percent ([**]%) of the amount that would otherwise have been payable under this Agreement, such amount to be paid in accordance with and subject to the other terms of this Agreement governing such payments, and (iii) in addition to all other rights that it may have

​

A-43

​

at law, Pfizer will have the right to offset, against any payment owing to Voyager hereunder, any damages awarded to Pfizer in a proceeding under Section 11.3 or agreed by the Parties to be owed by Voyager to Pfizer.

(ii)Complete Termination.  In the event that, on or following the Option Exercise Date, (a) Pfizer terminates this Agreement in its entirety pursuant to Section 10.3.2 or 10.3.3, and the event that gave rise to the right of termination materially impairs the ability to Exploit the Licensed Products in the United States, then (b) all licenses granted to Pfizer under this Agreement with respect to all Licensed Products will become irrevocable and perpetual, and Pfizer will have no further obligations to Voyager under this Agreement with respect to such Licensed Products, other than (i) those obligations that expressly survive termination in accordance with Section 10.7.3, (ii) an obligation to pay all milestones and royalties under Sections 5.3 and 5.4 with respect to such Licensed Products in an amount equal to [**] percent ([**]%) of the amount that would otherwise have been payable under this Agreement, such amount to be paid in accordance with and subject to the other terms of this Agreement governing such payments, and (iii) in addition to all other rights that it may have at law, Pfizer will have the right to offset, against any payment owing to Voyager hereunder, any damages awarded to Pfizer in a proceeding under Section 11.3 or agreed by the Parties to be owed by Voyager to Pfizer. The foregoing will not be construed to limit Voyager’s right to receive the full amount of any payments that accrued before the effective date of such termination.

10.7.2Accrued Rights. Termination or expiration of this Agreement for any reason will be without prejudice to any payments that accrued before the effective date of such termination or expiration or rights that will have accrued to the benefit of any Party prior to such termination or expiration, and any and all damages or remedies arising from any breach hereunder. Such termination or expiration will not relieve any Party from obligations which are expressly indicated to survive expiration or termination of this Agreement.

10.7.3Survival.

ARTICLE 11

MISCELLANEOUS

11.1Governing Law. This Agreement and any dispute arising from the performance or breach hereof will be governed by and construed and enforced in accordance with the Laws of the state of Delaware without reference to conflicts of laws principles; provided that with respect to

​

matters involving the enforcement of intellectual property rights, the Laws of the applicable country will apply. The provisions of the United Nations Convention on Contracts for the International Sale of Goods will not apply to this Agreement or any subject matter hereof.

11.2Dispute Resolution. If a dispute between the Parties arises under this Agreement, either Party will have the right to refer such dispute in writing to the respective Executive Officers, and such Executive Officers will attempt in good faith to resolve such dispute. If the Parties are unable to resolve a given dispute pursuant to this Section 11.2 within [**] after referring such dispute to the Executive Officers, either Party may have the given dispute settled by binding arbitration pursuant to Section 11.3 (subject to the exceptions specified therein).

11.3Arbitration Request. If a Party intends to begin an arbitration to resolve a dispute arising under this Agreement, such Party will provide written notice (the “Arbitration Request”) to the other Party of such intention and a statement of the issues for resolution. From the date of the Arbitration Request and until such time as the dispute has become finally settled, the running of the time periods as to which Party must cure a breach of this Agreement becomes suspended as to any breach that is the subject matter of the dispute.

11.3.1Additional Issues. Within [**] after the receipt of the Arbitration Request, the other Party may, by written notice, add additional issues for resolution in a statement of counter-issues.

11.3.2No Arbitration of Patent Issues. Notwithstanding anything to the contrary in this Agreement, any disputes, claims or controversies arising out of, or for which resolution depends in whole or in part on a determination of the ownership, inventorship, interpretation, validity, enforceability, or infringement of United States Patent rights will not be subject to arbitration under this Agreement, but instead may be brought by either Party in the United States District Court for the District of Delaware, before the United States Patent & Trademark Office, before United States appellate courts as applicable.

11.3.3Arbitration Procedure. Any arbitration pursuant to this Section 11.3 will be held in Boston, Massachusetts unless another location is mutually agreed by the Parties. The arbitration will be governed under the rules of the International Chamber of Commerce, to the exclusion of any inconsistent state Law. The Parties will mutually agree on the rules to govern discovery and the rules of evidence for the arbitration within [**] after the Arbitration Request. If the Parties fail to timely agree to such rules, the United States Federal Rules of Civil Procedure will govern discovery and the United States Federal Rules of Evidence will govern evidence for the arbitration. The arbitration will be conducted by three (3) arbitrators, of which each Party will appoint one, and the arbitrators so appointed will select the third and final arbitrator. The arbitrators will have experience of biotechnology and therapeutics licensing disputes. The arbitrators may proceed to an award, notwithstanding the failure of either Party to participate in the proceedings. The arbitrators will, within [**] after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The arbitrators will be limited in the scope of their authority to resolving only the specific matters which the Parties have referred to arbitration for resolution and will not have authority to render any decision or award on any other issues. Subject to Section 9.7, the arbitrators will be authorized to award compensatory

​

A-45

​

damages, but will not be authorized to award punitive, special, consequential, or any other similar form of damages, or to reform, modify, or materially change this Agreement. The arbitrators also will be authorized to grant any temporary, preliminary or permanent equitable remedy or relief the arbitrators deem just and equitable and within the scope of this Agreement, including an injunction or order for specific performance. The award of the arbitrators will be the sole and exclusive remedy of the Parties, except for those remedies that are set forth in this Agreement or which apply to a Party by operation of the applicable provisions of this Agreement, and the Parties hereby expressly agree to waive the right to appeal from the decisions of the arbitrators, and there will be no appeal to any court or other authority (government or private) from the decision of the arbitrators. Judgment on the award rendered by the arbitrator may be enforced in any court having competent jurisdiction thereof, subject only to revocation of the award on grounds set forth in the United Nations Convention on the Recognition and Enforcement of Foreign Arbitral Awards.

11.3.4Arbitration Expenses. Each Party will bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration, and will pay an equal share of the fees and costs of the arbitrator; provided, however, that the arbitrators, in their award, will be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, transcripts, photocopy charges and travel expenses).

11.3.5Preliminary Injunctions. Notwithstanding anything in this Agreement to the contrary, a Party may seek any remedy at law or in equity, including the issuance of a temporary restraining order or a preliminary, temporary, or permanent injunction from any court of competent jurisdiction in order to preserve or enforce its rights under this Agreement or to prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the award of the arbitrator on the ultimate merits of any dispute.

11.3.6Confidentiality. All proceedings and decisions of the arbitrator will be deemed Confidential Information of each of the Parties and will be subject to Article 7. For clarity, no information concerning an arbitration, beyond the names of the Parties and the relief requested, may be unilaterally disclosed to a third party by any party unless required by law. In addition, any documentary or other evidence given by a Party or witness in the arbitration shall be treated as Confidential Information by any Party whose access to such evidence arises exclusively as a result of its participation in the arbitration, and shall not be disclosed to any Third Party (other than a witness or expert), except as may be required by applicable Law.

11.4Assignment. This Agreement may not be assigned or otherwise transferred, nor may any right, interest, or obligation hereunder be assigned or transferred, by either Party without the written consent of the other Party; provided, however, that either Party may assign this Agreement or its rights and obligations under this Agreement to (a) a Third Party that acquires all or substantially all of the business or assets of such Party to which this Agreement relates (whether by merger, reorganization, acquisition, sale or otherwise), and agrees in writing to be bound by the terms of this Agreement, or (b) an Affiliate; provided that in each case of (a) and (b) the assignee will expressly agree to be bound by such Party’s obligations under this Agreement and that such Party will remain liable for all of its rights and obligations under this Agreement. Any purported assignment in violation of this Section 11.3 will be void. All terms of this Agreement will remain in full force and effect in the event of a Change of Control of either Party and will be binding upon

any Acquiring Entity of either Party. In addition, Pfizer may assign its rights and obligations under this Agreement to a Third Party where Pfizer or its Affiliate is required or makes a good-faith determination based on advice of legal counsel, to divest a Product in order to comply with Law or the order of any Governmental Authority as a result of a merger or acquisition, provided that the assignee will expressly agree to be bound by Pfizer’s obligations under this Agreement. Each Party will promptly notify the other Party of any assignment or transfer under the provisions of this Section 11.4.

11.5Performance by Affiliates and Sublicensees. Each Party may perform some or all of its obligations or exercise some or all of its rights under this Agreement through Affiliates; provided that each Party hereby acknowledges and agrees that it will be responsible for the full and timely performance and observance of all the covenants, terms, conditions and agreements set forth in this Agreement by its Affiliate(s) and Sublicensees.

11.6Force Majeure. No Party will be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this Agreement when such failure or delay is due to force majeure, whether or not foreseeable as of the Effective Date or thereafter. For purposes of this Agreement, force majeure is defined as any cause beyond the control of the affected Party and without the fault or negligence of such Party, which may include acts of God; material changes in Law; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemics, pandemics, and the spread of infectious diseases, including COVID-19 (as defined by the World Health Organization and any of the strains, variants, or mutations thereof); quarantines; and failure of public utilities or common carriers. In such event the Party affected by such force majeure will immediately notify the other Party of such inability and a good faith estimate of the period for which such inability is expected to continue based on currently available information. The Party giving such notice will thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as the condition constituting force majeure continues and the non-performing Party takes Commercially Reasonable Efforts to remove the condition, after which time the Parties will promptly meet to discuss in good faith how to best proceed in a manner consistent with this Agreement. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure.
