1.1.2.Promptly following execution of a Proposed New Company Agreement, in the event that such Proposed New Company Agreement is licensable or sublicensable to Vertex hereunder in accordance with the terms set forth therein, Company will provide to Vertex a copy of such Proposed New Company Agreement (which may be redacted to exclude provisions thereof that would not be applicable to Vertex as a licensee or sublicensee) with a summary of the terms of such agreement that would be applicable to Vertex as a licensee or sublicensee (as the case may be) thereunder (a “Licensee”) and any milestone and royalty payments that would be owed to such Grantor arising out of Vertex’s practice of the intellectual property subject to the applicable Proposed New Company Agreement. Company will discuss in good faith with Vertex to determine whether Vertex will take a license or sublicense (as the case may be) under all or a portion of the intellectual property rights that are the subject of such Proposed New Company Agreement. Following written notice by Vertex that it desires to have such intellectual property rights included in the license granted under this Agreement and be subject to the terms of such Proposed New Company Agreement that are applicable to a Licensee thereunder, such intellectual property rights described in such notice will automatically be deemed included in the Licensed Technology (any such Proposed New Company Agreement with respect to intellectual property rights that are included in the Licensed Technology pursuant to this sentence, a “New Company Agreement”). Any payment obligations arising under the New Company Agreements as a result of the license or sublicense granted to Vertex or the Research, Development, Manufacture or Commercialization of a Product in the Field by or on behalf of Vertex or any of its Affiliates or Sublicensees, after application of all available reductions to and deductions from such payment obligations under the applicable New Company Agreement (but, for the avoidance of doubt, excluding any such payment obligations of Company with respect to licensing or sublicensing income (as the case may be) received by Company), will be paid by Company and reimbursed by Vertex in accordance with this Section 5.7.2 and such amounts reimbursed by Vertex will be treated as Selected Third Party Intellectual Property Costs paid by Vertex pursuant to Section 5.4.5. Except as set forth in the immediately preceding sentence, Company will be responsible for all other payment obligations under such agreements (including any such payment obligations with respect to licensing or sublicensing income (as the case may be) received by Company). Company will provide Vertex with a reasonably detailed invoice for any payments made by Company under a New Company Agreement that are reimbursable by Vertex pursuant to this Section 5.7.2 within [***] of the end of each [***] in which any such payments were made by Company, and Vertex will pay the undisputed portion of such invoices within [***] of receipt thereof. All rights granted to Vertex under such New Company Agreement will be subject to the terms and conditions of such New Company Agreement and Vertex will comply with all terms of such New Company Agreement applicable to Vertex, its Affiliates or Sublicensees thereunder. For clarity, Vertex and its Affiliates will be obligated to reimburse a given amount owed under a New Company Agreement one time only. Notwithstanding the foregoing, Vertex may, in its sole discretion, notify Company that it elects to terminate its license or sublicense with respect to any New Company Agreement with [***] prior written notice, whereupon such termination, such New Company Agreement, as applicable, will be deemed not to be a New Company Agreement, as applicable, under this Agreement and the intellectual property rights licensed or sublicensed to Vertex thereunder will no longer constitute Licensed Technology, in which case, Vertex’s reimbursement obligations under this Section 5.7.2 will terminate with respect to such New Company Agreement. Except as otherwise provided in this Agreement, as between the Parties, Company will be responsible for all payments in connection with any New Company Agreement unless such payment obligations are resulted from the material breach of such New Company Agreement by Vertex.

1.1.3.Notwithstanding anything to the contrary herein, Company’s obligations under this Section 5.7 with respect to a Proposed New Company Agreement will not apply to the extent such Proposed New Company Agreement relates to Patents or Know-How that, pursuant to Section 1.46, Company and its Affiliates are deemed to not Control following a Change of Control.

1.8.Funding.

1.1.1.Cost Reimbursement. Vertex will reimburse Company for (a) its FTE Costs, Out-of-Pocket Costs, and Manufacturing Costs actually incurred by Company or its Affiliates for Research Activities performed in accordance with Research Plan and Research Budget; provided that (i) Vertex will not reimburse Company for any FTE Costs, Out-of-Pocket Costs, or Manufacturing Costs incurred during any [***] in the conduct of Research Activities in excess of [***]% of the relevant Research Budget for such [***] and (ii) Company will be solely responsible for all such excess expenses above [***]% of the Research Budget incurred during such [***], unless (A) the cause of the excess expenditure is [***] or (B) otherwise agreed in writing by Vertex (including pursuant to a revised Research Budget), and (b) Manufacturing Costs actually incurred by Company for any ENTR-701 Manufactured and supplied to Vertex for its Development activities pursuant to the Supply Agreement. Vertex will be responsible for its costs and expenses incurred in the performance of Research Activities.

1.1.2.Additional Research Costs. Vertex will reimburse Company for its FTE Costs and Out-of-Pocket Costs actually incurred by Company or its Affiliates for Additional Research Activities performed in accordance with Additional Research Plan and Additional Research Budget; provided that (a) Vertex will not reimburse Company for any FTE Costs or Out-of-Pocket Costs incurred during any [***] in the conduct of Additional Research Activities in excess of [***]% of the relevant Additional Research Budget for such [***] and (b) Company will be solely responsible for all such excess expenses above [***]% of the Additional Research Budget incurred during such [***], unless (A) the cause of the excess expenditure is [***] or (B) otherwise agreed in writing by Vertex (including pursuant to a revised Additional Research Budget).

1.1.3.Payments. Any payments to be made to Company by Vertex pursuant to this Section 5.8 will be made [***] in arrears pursuant to invoices submitted by Company to Vertex within [***] following the end of the applicable [***] for which such costs have been incurred; provided that Company will provide a good faith written estimate of any costs for which reimbursement is due under this Section 5.8 within [***] after each [***]. Each such invoice will be accompanied by reasonable supporting documentation evidencing the expenses incurred for Research Activities or Additional Research Activities, including Manufacturing activities, (such activities to be itemized) during such [***]. Undisputed payments will be due within [***] after Vertex receives such an invoice from Company. The Parties agree to discuss in good faith to resolve any payment disputes within [***] of such dispute.

1.9.Payment Terms.

1.1.1.Currency; Payment Method. All payments under this Agreement are expressed in U.S. Dollars and will be paid in U.S. Dollars, in immediately available funds by wire transfer or Automated Clearing House (ACH) payment to an account designated by Company (which account Company may update from time to time in writing).

1.1.2.Exchange; Interest. If any amounts that are relevant to the determination of amounts to be paid under this Agreement or any calculations to be performed under this Agreement are denoted in a currency other than U.S. Dollars, such amounts will be

converted to their U.S. Dollar equivalent using Vertex’s then-current standard procedures and methodology, including its then-current standard exchange rate methodology for the translation of foreign currency expenses into U.S. Dollars or, in the case of Sublicensees, such similar methodology, consistently applied. Calculation of Net Sales will exclude hedging and foreign exchange gain or loss realized through a hedging program. Interest will be payable by Vertex on any amounts payable to Company under this Agreement which are not paid by the date they become due. All interest will accrue (both before and after any judgment) at an annual rate equal to [***] percentage points above the United States effective Federal Funds Rate, on the date such payment first became due (but in no event in excess of the maximum rate permissible by Applicable Law).

1.10.Withholding Tax. Where any sum due to be paid to Company hereunder is subject to any withholding or similar tax as required by Applicable Law, Vertex will pay such withholding or similar tax to the appropriate Governmental Authority and deduct the amount paid from the amount then due to Company. Vertex will in a timely manner transmit to Company an official tax certificate or other evidence of such withholding sufficient to enable Company to claim such payment of taxes. The Parties will cooperate with one another and use reasonable efforts to reduce or eliminate tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by Vertex to Company under this Agreement. Company will provide Vertex any tax forms that may be reasonably necessary in order for Vertex not to withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Laws, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax. Notwithstanding anything in this Agreement to the contrary, if any assignment, or sublicense or a similar transfer of rights or obligations under this Agreement (including through merger or acquisition) by Vertex leads to the imposition of withholding tax liability on any amounts payable under this Agreement that would not have been imposed in the absence of such action or in an increase in such liability above the liability that would have been imposed in the absence of such action, then the sum payable by Vertex (in respect of which such deduction or withholding is required to be made) will be increased to the extent necessary to ensure that Company receives a sum equal to the sum which it would have received had no such action occurred.

1.11.Records; Audits. Vertex and its Affiliates will, and will cause their respective Sublicensees to, keep and maintain accurate and complete records regarding Net Sales during the [***]. Company and its Affiliates will, and will require their respective Subcontractors to, keep accurate and complete records regarding all FTE Costs and Out-of-Pocket Costs incurred in connection with the performance of Research Activities and Additional Research Activities in sufficient detail to confirm the accuracy of any payments required under this Agreement, covering the [***]. Upon [***] prior written notice from the other Party (the “Auditing Party”), the Party required to maintain such records (as applicable, the “Audited Party”) will permit an independent certified public accounting firm of internationally recognized standing, selected by the Auditing Party and reasonably acceptable to the Audited Party, to examine the relevant books and records of the Audited Party and its Affiliates and Sublicensees as may be reasonably necessary to verify the royalty reports submitted by Vertex in accordance with Section 5.4.6 or the FTE Costs and Out-of-Pocket Costs reported by Company in accordance with Section 5.8.1 and Section 5.8.2, as applicable. An examination by the Auditing Party under this Section 5.11 will occur not more than [***] and will be limited to the pertinent books and records for any [***] ending not more than [***] before the date of the request. The accounting firm will be provided access to such books and records at the Audited Party’s facility or facilities where such books and records are normally kept and such examination will be conducted during the Audited Party’s normal business hours. The Audited Party may require the accounting firm to sign a customary non-disclosure agreement before providing the accounting

firm access to its facilities or records. Upon completion of the audit, the accounting firm will provide both Parties a written report disclosing whether the reports submitted by Vertex or the FTE Costs and Out-of-Pocket Costs submitted by Company, as applicable, are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to the Auditing Party. If the report or information submitted by the Audited Party resulted in an underpayment or overpayment, the Party owing the underpaid or overpaid amount will promptly pay such amount to the other Party. The costs and fees of any audit conducted by the Auditing Party under this Section 5.11 will be borne by the Auditing Party, unless such audit reveals an underpayment of amounts owed to or an overpayment of amounts owed by the Auditing Party of more than [***] percent of the amount that was owed by the Audited Party or owed to the Audited Party, as applicable, with respect to the relevant period, in which case, the Audited Party will reimburse the Auditing Party for the reasonable expense incurred by the Auditing Party in connection with the audit.

Except as expressly provided in this Agreement, neither Party will have any obligation to account to the other for profits with respect to, or to obtain any consent of the other Party to license or exploit, Joint Agreement Technology by reason of joint ownership thereof, and each Party hereby waives any right it may have under the laws of any jurisdiction to require any such consent or accounting.

1.2.Prosecution and Maintenance of Patents.

1.1.1.Company Agreement Patents. As between the Parties, Company will have the sole right, at Company’s expense, to control the Prosecution and Maintenance of the Patents within the Company Agreement Patents that are not Licensed Patents.

1.1.2.Vertex Agreement Patents. As between the Parties, Vertex will have the sole right, at Vertex’s expense, to control the Prosecution and Maintenance of the Vertex Agreement Patents.

1.1.3.Licensed Platform Patents. As between the Parties, [***] will have the first right (but not the obligation) to Prosecute and Maintain the Licensed Platform Patents at [***]’s own expense using patent counsel that is reasonably acceptable to [***]. [***] agrees to keep [***] reasonably informed with respect to the Prosecution and Maintenance of such Licensed Platform Patents and consult in good faith with [***] regarding such matters. If [***] intends to abandon any such Licensed Platform Patent that [***] is responsible for Prosecuting and Maintaining in a particular country, then [***] will notify [***] of such intention at least [***] before such Patent will become abandoned. Following such notice, [***] may elect, upon written notice to [***], to control the Prosecution and Maintenance thereof at its own expense with counsel of its own choice. Upon such election, [***] will cooperate and assist in transitioning the Prosecution and Maintenance of such Patent to [***].

1.1.4.Licensed Product-Specific Patents. As between the Parties, [***] will have the first right (but not the obligation) to Prosecute and Maintain the Licensed Product-Specific Patents at [***]’s own expense. [***] agrees to keep [***] reasonably informed with respect to the Prosecution and Maintenance of Licensed Product-Specific Patents (including providing copies of any office actions or office action responses or other correspondence that [***] provides to or receives from any patent office, including notice of all interferences, reissues, re-examinations, or oppositions, and all patent-related filings of such Licensed Product-Specific Patents), to consult in good faith with [***] regarding such matters, and to [***] with respect to such matters. If [***] intends to abandon any such Licensed Product-Specific Patent that [***] is responsible for Prosecuting and Maintaining in a particular country, then [***] will notify [***] of such intention at least [***] before such Patent will become abandoned. Following such notice, [***] may elect, upon written notice to [***], to control the Prosecution and Maintenance thereof at its own expense with counsel of its own choice. Upon such election, [***] will cooperate and assist in transitioning the Prosecution and Maintenance of such Licensed Product-Specific Patent to [***]. Promptly following the Effective Date, the Parties will aim to agree on, and will thereafter comply with, a Patent filing strategy that allows for [***].

1.1.5.Other Joint Patents. Upon identification of any Joint Agreement Patent that is not a Licensed Patent (such Patents, the “Other Joint Patents”), the Parties will discuss in good faith and determine which Party will be primarily responsible for the Prosecution and Maintenance of such Other Joint Patent. The Party primarily responsible for such Prosecution and Maintenance of a particular Other Joint Patent (the “Lead Prosecuting Party”) will conduct such Prosecution and Maintenance, at its expense, using counsel reasonably acceptable to the other Party. The Lead Prosecuting Party will keep the other Party reasonably informed with respect to such Prosecution and Maintenance and consult in good faith with such other Party regarding such matters. If the Lead Prosecuting Party decides to abandon an Other Joint Patent that is not a Licensed Patent, it will provide the other Party with notice at least [***] prior to the date such abandonment would become effective. Following such notice, the other Party may elect, upon written notice to the Lead Prosecuting Party, to control the Prosecution and Maintenance of such Patent at its own expense.

1.3.Defense of Claims Brought by Third Parties. If any Third Party brings a claim or otherwise asserts that a Product or Licensed Agent infringes such Third Party’s Patent

or misappropriates such Third Party’s Know-How (each, a “Third-Party Infringement Claim”), the Party first having notice of the claim or assertion will promptly notify the other Party in writing. Subject to Section 8.1, [***] will have the sole right to undertake and control the defense or settlement of any Third-Party Infringement Claim using counsel of its choice, at its expense. Subject to Section 8.1, if [***] is named as a defendant in any such Third Party Infringement Claim, [***] will have the right to participate in such defense and settlement with its own counsel, at its expense. Subject to Section 8.1, [***] will not enter into any settlement of any Third-Party Infringement Claim that is instituted or threatened to be instituted against [***] without [***]’s prior written consent, which will not be unreasonably withheld, conditioned or delayed; provided that such consent will not be required if [***]. As requested by [***], [***] will provide reasonable cooperation and assistance to [***] in connection with [***]’s control of the defense or settlement of a Third-Party Infringement Claim. Such cooperation and assistance will include executing all necessary and proper documents and taking such actions as will be appropriate to allow [***] to control the defense and settlement of such Third-Party Infringement Claim.

[***] will keep [***] reasonably informed of the progress of any Third Party Infringement Claim. To the extent reasonable, both Parties will cooperate in good faith to [***].

1.4.Enforcement of Patents Against Competitive Infringement.

1.1.1.Duty to Notify of Competitive Infringement. If either Party learns of an infringement, unauthorized use, misappropriation, threatened infringement, or a request for a compulsory license by a Third Party with respect to any Licensed Technology by reason of the making, using, offering to sell, selling, importing or other exploitation of a compound or product in the [***] (a “Competitive Infringement”), such Party will promptly notify the other Party in writing and will provide such other Party with available information regarding such Competitive Infringement.

1.1.2.Enforcement.

(a)[***] will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding under any Licensed Product-Specific Patent with respect to any Competitive Infringement by counsel of its own choice, at its own expense. If [***] fails to initiate such a Proceeding within [***] after written notice of such Competitive Infringement is first provided by a Party under Section 6.4.1, or [***] if such Proceeding is an ANDA litigation, other than with respect to a request for a compulsory license, [***] will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice, at its own expense and [***] will have the right, at its own expense, to be represented in any such action by counsel of its own choice; provided that, if [***] notifies Company during such [***] period (or such [***] period for a Proceeding that is an ANDA litigation) that [***], then [***] will not have the right to initiate and control any Proceeding with respect to such Competitive Infringement (other than as provided in Section 6.4.2(b)).

(b)[***] will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding under any Licensed Platform Patent with respect to any Competitive Infringement by counsel of its own choice, at its own expense. If [***] fails to initiate such a Proceeding within [***] after written notice of such Competitive Infringement is first provided by a Party under Section 6.4.1, or [***] if such Proceeding is an ANDA litigation, other than with respect to a request for a compulsory license, [***] will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own

choice, at its own expense; provided that if (i) [***] notifies Vertex during such [***] period (or such [***] period for a Proceeding that is an ANDA litigation) that [***] will not have the right to initiate, prosecute and control any Proceeding under the Licensed Platform Patents with respect to such Competitive Infringement.

(c)The Lead Prosecuting Party will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding under any Other Joint Patent with respect to any Competitive Infringement by counsel of its own choice, at its own expense. If the Lead Prosecuting Party fails to initiate such a Proceeding within [***] after written notice of such Competitive Infringement is first provided by the other Party under Section 6.4.1, or [***] if such Proceeding is an ANDA litigation, other than with respect to a request for a compulsory license, the other Party will have the right to initiate and control a Proceeding with respect to such Competitive Infringement by counsel of its own choice, at its own expense; provided that if (x) (i) [***] is the Lead Prosecuting Party and it notifies [***] during such [***] period (or such [***] period for a Proceeding that is an ANDA litigation) that [***] will not have the right to initiate, prosecute and control any Proceeding under the Other Joint Patents with respect to such Competitive Infringement or (y) if [***] is the Lead Prosecuting Party and it notifies [***] during such [***] period (or such [***] period for a Proceeding that is an ANDA litigation) that [***] will not have the right to initiate and control any Proceeding with respect to such Competitive Infringement.

(d)The Party prosecuting and controlling any such Proceeding will (i) keep the other Party reasonably apprised of the progress of such Proceeding, (ii) reasonably consider the other Party’s comments with respect to the conduct of such Proceeding and (iii) not enter into a settlement, consent judgment or other voluntary final disposition of a Proceeding that [***] without the other Party’s prior written consent, not to be unreasonably withheld, conditioned, or delayed; provided that [***].

1.1.3.Joinder.

(a)If a Party initiates a Proceeding in accordance with this Section 6.4, the other Party agrees to be joined as a party plaintiff where necessary and to give the first Party reasonable assistance and authority to file and prosecute the Proceeding. Subject to Section 6.4.4, the costs and expenses of each Party incurred pursuant to this Section 6.4.3(a) will be borne by the Party initiating such Proceeding.

(b)If one Party initiates a Proceeding in accordance with this Section 6.4, the other Party may join such Proceeding as a party plaintiff where necessary for such other Party to seek lost profits with respect to such infringement.

1.1.4.Share of Recoveries. Any damages or other monetary awards recovered with respect to a Proceeding brought pursuant to this Section 6.4 will be shared as follows:

(a)the amount of such recovery will first be applied to the Parties’ reasonable Out-of-Pocket Costs incurred in connection with such Proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); then

(b)any remaining proceeds constituting direct or actual damages for acts of infringement will be paid to, or retained by, [***]; provided that such amounts will be [***]; and

(c)any remaining proceeds constituting [***] will be allocated between the Parties as follows: the Party initiating the Proceeding will retain [***]% of such proceeds and the other Party will receive [***]% of such proceeds.

1.1.5.Settlement. Notwithstanding anything to the contrary under this ARTICLE 6, neither Party may enter a settlement, consent judgment or other voluntary final disposition of a suit under this ARTICLE 6 that disclaims, limits the scope of, admits the invalidity or unenforceability of, or grants a license, covenant not to sue or similar immunity under a Patent Controlled by the other Party or its Affiliates without first obtaining the written consent of the Party that Controls the relevant Patent; provided that the foregoing restriction on granting a license will not apply with respect to any Sublicense granted by Vertex.

1.5.Other Infringement.

1.1.1.Joint Agreement Patents. With respect to the infringement of a Joint Agreement Patent that is not a Competitive Infringement, neither Party will enforce any Joint Agreement Patent unless mutually agreed by the Parties; provided that the Parties will cooperate in good faith to bring suit together against such infringing party or the Parties may decide to permit one Party to solely bring suit. Any damages or other monetary awards recovered with respect to a Proceeding brought pursuant to this Section 6.5.1 will be shared as follows: (a) the amount of such recovery will first be applied to the Parties’ reasonable Out-of-Pocket Costs incurred in connection with such Proceeding (which amounts will be allocated pro rata if insufficient to cover the totality of such expenses); then (b) any remaining proceeds will be allocated as follows: (i) if the Parties jointly initiate a Proceeding pursuant to this Section 6.5.1, [***]; and (ii) if only one Party initiates the Proceeding pursuant to this Section 6.5.1, such Party will retain [***]% of such proceeds and the other Party will receive [***]% of such proceeds.

1.1.2.Patents Solely Owned by Company. Company will retain all rights to pursue (a) an infringement of any Patent solely owned by Company that is not a Competitive Infringement and (b) an infringement of any Patent solely owned by Company that is not included in the Licensed Technology, and, in each case of (a) and (b), Company will retain all recoveries with respect thereto.

1.1.3.Patents Solely Owned by Vertex. Vertex will retain all rights to pursue an infringement of any Patent solely owned by Vertex and Vertex will retain all recoveries with respect thereto.

1.6.Patent Listing. [***] will have the sole right, but not the obligation, to submit to all applicable Regulatory Authorities patent information pertaining to each applicable Product pursuant to 21 U.S.C. § 355(b)(1)(G), any similar statutory or regulatory requirement enacted in the future regarding biologic products, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction.

1.7.Common Ownership Legislation. Notwithstanding anything to the contrary in this ARTICLE 6, neither Party will have the right to make an election under the Common Ownership Legislation when exercising its rights under this ARTICLE 6 without the prior written consent of the other Party, which will not be unreasonably withheld, conditioned or delayed. With respect to any such permitted election, the Parties will use reasonable efforts to cooperate and coordinate their activities with respect to any submissions, filings or other activities in support thereof. The Parties acknowledge and agree that this Agreement is a “joint research agreement” as defined in the Common Ownership Legislation. Notwithstanding the foregoing, the other Party’s consent under this Section 6.7 will not be required in connection with an obviousness-type double patenting rejection in any patent application claiming a Licensed Agent, Product, or uses thereof.

1.8.Patent Term Extension. [***] will have the sole right, at its sole cost, to obtain patent term restoration in any country in the Territory under 35 U.S.C. § 156 or any statute or regulation equivalent or similar thereto, where applicable to a Product and where such patent term restoration arises from, or is calculated in reference to, the Development of a Product or Licensed Agent, including with respect to any [***], except as provided below with respect to [***]. [***] will determine which relevant patents will be extended (including by filing supplementary protection certificates and any other extensions that are now or in the future become available); provided, however, that any decision to [***] will require the prior written approval of [***], which may be withheld in [***]’s sole discretion. [***] will cooperate, at [***]’s cost, as reasonably requested by [***], in connection with the foregoing (including by providing appropriate information and executing appropriate documents). For clarity, [***] will have the sole right to obtain patent term restoration in any country in the Territory for any [***] where such patent term restoration arises from, or is calculated in reference to, [***].

1.9.Recording. If Vertex deems it necessary or desirable to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate Governmental Authority in one or more jurisdictions in the Territory, Company will reasonably cooperate to execute and deliver to Vertex any documents accurately reflecting or evidencing this Agreement that are necessary or desirable, in Vertex’s reasonable judgment, to complete such registration or recordation. Vertex will reimburse Company for all reasonable Out-of-Pocket Costs, including attorneys’ fees, incurred by Company in complying with the provisions of this Section 6.9.

1.10.Unitary Patent System. The Party Prosecuting and Maintaining a Patent in Europe pursuant to Section 6.2 will have the exclusive right to opt-in or opt-out of the Europe Unitary Patent System for such Patent. For clarity, “to opt-in or opt-out” refers to both the right to have or have not a European patent application or an issued European patent registered to have unitary effect within the meaning of Regulation (EU) No 1257/2012 of December 17, 2012 as well as the Agreement on a Unified Patent Court as of February 19, 2013; and to the right to opt-in or opt-out from the exclusive competence of the Unified Patent Court in accordance with Article 83(3) of that Agreement on a Unified Patent Court. Without limiting the generality of the foregoing, unless a Party or its Affiliate has expressly opted in to the Europe Unitary Patent System with respect to a given Patent, the other Party will not initiate any action with respect to such Patent under the Europe Unitary Patent System without such Party’s prior written approval, such approval to be granted or withheld in such Party’s sole discretion.

1.11.Trademarks. As between the Parties, all trademarks and trade dress rights used in connection with the Commercialization of the Products in the Field in the Territory will be owned exclusively by Vertex.

1.12.Bankruptcy.

1.1.1.All rights and licenses now or hereafter granted by Company to Vertex under or pursuant to this Agreement, including, for the avoidance of doubt, the licenses granted to Vertex pursuant to Section 4.1, are, for all purposes of 11 U.S.C. § 365(n), licenses of rights to “intellectual property” as defined in the U.S. Bankruptcy Code. Upon the occurrence of any Insolvency Event with respect to Company, Company agrees that Vertex, as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. Without limiting the generality of the foregoing, the Parties intend and agree that any sale of Company’s assets under Section 363 of the Bankruptcy Code will be subject to Vertex’s rights under Section 365(n), that Vertex cannot be compelled to accept a money satisfaction of its interests in the intellectual property licensed pursuant to this Agreement, and that any such sale therefore may not be made to a purchaser “free and clear” of Vertex’s rights under this Agreement and Section 365(n) without the express, contemporaneous

consent of Vertex. Further, each Party agrees and acknowledges that all payments by Vertex to Company hereunder, other than the up-front fee pursuant to Section 5.1, royalty payments pursuant to Section 5.4, and the milestone payments pursuant to Section 5.3.1 and Section 5.3.2, do not constitute royalties within the meaning of Section 365(n) of the Bankruptcy Code or relate to licenses of intellectual property hereunder. Company will, during the Term, create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all intellectual property licensed under this Agreement. Each Party acknowledges and agrees that “embodiments” of intellectual property within the meaning of Section 365(n) include laboratory notebooks, cell lines, product samples and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference therein, the Licensed Technology and all information related to the Licensed Technology. If (a) a case under the U.S. Bankruptcy Code is commenced by or against Company, (b) this Agreement is rejected as provided in the U.S. Bankruptcy Code, and (c) Vertex elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code, Company (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will:

(a)provide Vertex with copies of all such intellectual property (including all embodiments thereof) held by Company; and

(b)not interfere with Vertex’s rights under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity.

Nothing herein will be deemed a waiver by Vertex of any claims it may have against Company resulting from rejection of the license or failure to perform its obligations hereunder.

INDEMNIFICATION; INSURANCE; LIMITATIONS

1.1.Indemnification.

1.1.1.Indemnification by Vertex. Subject to Section 8.1.3, Vertex will indemnify Company, its Affiliates, and its and its Affiliates’ employees, officers and directors (each, a “Company Indemnified Party”) from and against any liability, loss, damage or expense (including reasonable attorneys’ fees and expenses) (collectively, “Liability”) that the Company Indemnified Party may incur or otherwise be required to pay to one or more Third Parties in connection with any Third Party suit, investigation, claim or demand resulting from or arising out of:

(a)the Exploitation of any Licensed Agent or Product by, on behalf of, or under the authority of, Vertex;

(b)the breach by Vertex of any of its representations, warranties or covenants set forth in this Agreement; or

(c)the gross negligence or willful misconduct of Vertex or any Vertex Indemnified Party;

and except, in each case ((a)–(c)), to the extent such claim results from or arises out of an event described in clause (a) through (b) of Section 8.1.2, as to such claim each Party will indemnify the other to the extent of their respective liability.

1.1.2.Indemnification by Company. Subject to Section 8.1.3, Company will indemnify Vertex, its Affiliates and its and its Affiliates’ employees, officers and directors, Sublicensees and Distributors (each, a “Vertex Indemnified Party”) from and against any Liability that the Vertex Indemnified Party may incur or otherwise be required to pay to one or more Third Parties in connection with any Third Party suit, investigation, claim or demand resulting from or arising out of:

(a)the breach by Company of any of its representations, warranties or covenants set forth in this Agreement; or

(b)the gross negligence or willful misconduct of Company or any Company Indemnified Party;

and except, in each case ((a)–(b)), to the extent such claim results from or arises out of an event described in clause (a) through (c) of Section 8.1.1, as to such claim each Party will indemnify the other to the extent of their respective liability.

1.1.3.Procedure. Each Party will notify the other Party in writing if it becomes aware of a claim for which such Party may seek indemnification hereunder. If any Proceeding is instituted against a Party (or another Company Indemnified Party in the case of Company or another Vertex Indemnified Party in the case of Vertex) with respect to which indemnity may be sought pursuant to Section 8.1.1 or 8.1.2, as applicable, such Party (the “Indemnified Party”) will give prompt written notice of the indemnity claim to the other Party (the “Indemnifying Party”) and provide the Indemnifying Party with a copy of any complaint, summons or other written notice that the Company Indemnified Party or Vertex Indemnified Party, as applicable, receives in connection with any such claim. An Indemnified Party’s failure to deliver such written notice will relieve the Indemnifying Party of liability to the Company Indemnified Party or Vertex Indemnified Party under Section 8.1.1 or 8.1.2, as applicable, only to the extent such delay is prejudicial to the Indemnifying Party’s ability to defend such claim; provided that the Indemnifying Party is not contesting the indemnity obligation, the Company Indemnified Party or Vertex Indemnified Party, as applicable, will permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by negotiated settlement or otherwise (subject to this Section 8.1) and any failure to contest such obligation prior to assuming control will be deemed to be an admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect to all matters relating to such claim and will not settle or otherwise resolve such claim without the prior written consent of the Company Indemnified Party or Vertex Indemnified Party, as applicable, which will not be unreasonably withheld, conditioned or delayed; provided that such consent will not be required with respect to any settlement involving only the payment of monetary awards for which the Indemnifying Party will be fully responsible. The Indemnified Party will cooperate with the Indemnifying Party in the Indemnifying Party’s defense of any claim for which indemnity is sought under this Agreement, at the Indemnifying Party’s cost and expense.

1.2.Insurance. Throughout the Term and for [***] thereafter, each Party will respectively, at its cost, obtain and maintain the insurance coverage listed below, each naming the other Party and its Indemnified Parties as additional insureds, from insurance carriers licensed to do business under the laws of the country, state, commonwealth, province or territory in which such Party’s obligations are provided, with insurers that carry a rating of at least an A-VII or better from A.M. Best. Each Party will furnish to the other Party evidence of such insurance upon request.

(a)Vertex’s Right to Terminate. If Vertex believes that Company is in material breach of this Agreement, Vertex may deliver written notice of such material breach to Company.

If Company fails to cure such breach within such [***] period or the breach is not subject to cure (a “Company Breach Event”), (i) Vertex may terminate this Agreement by providing written notice to Company, in which case, this Agreement will terminate on the date on which Company receives such written notice or (ii) Vertex may elect to exercise the alternate remedy provisions set forth in Section 9.3; provided, however, that if (A) the relevant breach is curable, but not reasonably curable within [***], and (B) Company is making a bona fide effort to cure such breach, Vertex’s right to

(b)Company’s Right to Terminate. If Company believes that Vertex is in material breach of this Agreement, Company may deliver written notice of such material breach to Vertex. If the breach is curable, Vertex will have [***] following its receipt of such written notice to cure such breach (except to the extent such breach involves the failure to make a payment when due, which breach must be cured within [***] following its receipt of such written notice). If Vertex fails to cure such breach within the [***] or [***] period, as applicable, or the breach is not subject to cure, Company may terminate this Agreement by providing written notice to Vertex, in which case, this Agreement will terminate on the date on which Vertex receives such written notice; provided, however, that if (i) the relevant breach (A) does not involve Vertex’s failure to make a payment when due and (B) is curable, but not reasonably curable within [***], and (ii) Vertex is making a bona fide effort to cure such breach, Company’s right to terminate this Agreement on account of such breach will be suspended for so long as Vertex is continuing to make such bona fide effort to cure such breach (up to a maximum of [***] after receipt of the applicable written notice above) and if such breach is successfully cured within the foregoing [***] period, Company will no longer have the right to terminate this Agreement on account of such breach.

1.1.4.Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in Section 9.2.3 disputes in good faith the existence, materiality, or failure to cure of any breach, and provides written notice to the Non-Breaching Party of such dispute within the relevant cure period, the Non-Breaching Party will not have the right to terminate this Agreement in accordance with Section 9.2.3, or the right to exercise the alternative remedy provisions of Section 9.3, as applicable, unless and until the relevant dispute has been resolved in accordance with Section 11.12. During the pendency of such dispute, the relevant cure period will be tolled, all the terms of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder.

1.1.5.Termination for Insolvency. If either Party makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or code, including the U.S. Bankruptcy Code, or has any such petition filed against it that is not discharged within [***] after the filing thereof (each, an “Insolvency Event”), the other Party may terminate this Agreement in its entirety by providing written notice of its intent to terminate this Agreement to such Party, in which case, this Agreement will terminate on the date on which such Party receives such written notice.

1.3.Alternative Remedies to Termination. If Vertex has the right to terminate this Agreement pursuant to Section 9.2.3(a), in addition to any other remedies available to Vertex in law or equity, in lieu of terminating this Agreement, Vertex may elect, upon written notice to Company, to reduce the milestone payments under Section 5.3 by [***]% and royalty payments under Section 5.4 by [***]% (after giving effect to all other applicable deductions and credits available under such Section 5.4). Company stipulates and agrees that such reductions would be a reasonable remedy in such circumstance and not a penalty. For clarity, if Vertex exercises the alternative remedy set forth above in this Section 9.3, such remedy will be Vertex’s sole remedy for such breach.

1.4.Patent Challenge. Company has the right to terminate this Agreement upon written notice to Vertex in the event that Vertex or any of its Affiliates or Sublicensees directly or indirectly challenges in a legal or administrative proceeding the patentability, enforceability, or validity of any Licensed Patent (a “Patent Challenge”). In the event of such a Patent Challenge, Company will provide written notice of such Patent Challenge to Vertex, and if Vertex (a) with respect to a patent challenge brought by Vertex or an Affiliate of Vertex, fails to withdraw such Patent Challenge within [***] after such receipt of such notice or (b) with respect to a Patent Challenge brought by a Sublicensee, fails to cause the Sublicensee to withdraw such Patent Challenge within [***] after such receipt of such notice or to terminate the applicable sublicense agreement for such Sublicensee within [***] after receipt of such notice, then, in either case of (a) or (b), Company may terminate this Agreement by providing written notice of such termination to Vertex. As used herein, a Patent Challenge includes: (i) filing an action under 28 U.S.C. §§ 2201-2202 seeking a declaration of invalidity or unenforceability of any such Patent; (ii) filing, or joining in, a petition under 35 U.S.C. § 311 to institute inter partes review of any such Patent; (iii) filing, or joining in, a petition under 35 U.S.C. § 321 to institute post-grant review of any such Patent or any portion thereof; (iv) filing or commencing any opposition, nullity, or similar proceedings challenging the validity of any such Patent in any country or region; or (v) any foreign equivalent of clauses (i), (ii), (iii) or (iv), including under Applicable Law. Notwithstanding the foregoing, Company will not have the right to terminate this Agreement under this Section 9.4 (x) with respect to any Patent Challenge in which Vertex or its Affiliate or Sublicensee has been compelled to participate in such Patent Challenges by a court or patent office or (y) if a Patent Challenge is necessary or reasonably required to assert a cross claim or a counterclaim or to respond to a court request or order or administrative law request or order, including asserting any defense or counterclaim in, or otherwise responding to, any Patent infringement suit filed by Company or any of its Affiliates, licensors, licensees or sublicensees against Vertex or any of its Affiliates or Sublicensees. In addition, Company will not have the right to terminate this Agreement pursuant to this Section 9.4 if any Affiliate that first becomes an Affiliate of Vertex pursuant to a Change of Control of Vertex after the Effective Date was undertaking activities in connection with a Patent Challenge prior to such Affiliate first becoming an Affiliate of Vertex.

1.5.Termination for Cessation of Development or Commercialization. Without prejudice to any other remedies available to it at law or in equity (including for any breach of the terms hereof), if (i) Vertex does not conduct, or cause to be conducted, any Research, Development or Commercialization activities (which Research, Development or Commercialization activities will include planning for such activities, contracting for such activities, performing activities to address or resolve clinical holds imposed by Regulatory Authorities, pending supply interruptions, or other circumstances of events outside the reasonable control of Vertex, its Affiliates or its Sublicensees), or otherwise ceases or abandons all Research, Development or Commercialization activities, in each case with respect to all Licensed Agents and Products for a period of [***] at any time during the Term, then Company will have the right to terminate this Agreement in its entirety with [***] written notice to Vertex, unless within such [***] period Vertex provides to Company reasonably suitable documentation evidencing that Vertex has resumed material Research, Development and Commercialization activities with respect to any Licensed Agents or Products; provided that such [***] period will be tolled during the pendency of any bona fide dispute between the Parties as to whether such cessation has occurred. Any such disputes will be resolved through the dispute resolution procedures set forth in Section 11.12.

1.6.Consequences of Expiration or Termination of the Agreement.

1.1.1.In General. If this Agreement expires or is terminated in whole or in part with respect to one or more Products by a Party pursuant to this ARTICLE 9, the

following terms will apply to this Agreement, either in its entirety or with respect to the Product that is the subject of such termination, as the case may be:

1.1.2.Early Termination. If this Agreement is terminated in its entirety or in part by a Party pursuant to Sections 9.2.2, 9.2.3, 9.2.5, 9.5 or 9.5, the following terms will apply with respect to any Product that is the subject of such termination (i.e., all Products worldwide in the case of termination of this Agreement in its entirety or the applicable Product in the Territory in the case of termination of this Agreement for a particular Product, as the case may be):

(a)except as set forth in Section 9.6.2.(e), the applicable licenses granted by Company to Vertex with respect to such Product(s) in the Territory under this Agreement will terminate;

(c)if terminated with respect to a particular Product or Products, the definition of Product will be automatically amended to exclude the relevant Product or Products;

(d)any permitted Sublicense of Vertex will, at the applicable Sublicensee’s option, survive such termination on the condition that the relevant Sublicensee is not in material breach of any of its obligations under such Sublicense. In order to effect this

provision, at the request of the Sublicensee, Company will enter into a direct license with the Sublicensee on terms that are substantially the same terms as the applicable terms of this Agreement; provided that Company will not be required to undertake obligations in addition to those required by this Agreement, and Company’s rights under such direct license will be consistent with its rights under this Agreement, taking into account the scope of the license granted under such direct license;

(e)if there are any on-going Development or Commercialization activities being conducted by or on behalf of Vertex, the Parties will negotiate in good faith and adopt a plan to wind-down such activities in an orderly fashion or, at Company’s election, Vertex will promptly transition such activities from Vertex to Company or its designee, with due regard for patient safety and the rights of any subjects that are participants in any clinical studies of the terminated Product, and take any actions it deems reasonably necessary or appropriate to avoid any human health or safety problems and in compliance with all Applicable Laws;

(f)except with respect to any termination by Vertex under Section 9.2.3(a), Vertex (A) will, and hereby does, assign, and will cause its Affiliates and any Sublicensee that does not elect to become a direct licensee of Company to assign, effective as of the effective date of termination, to Company all of its rights, title, and interests in and to all Regulatory Filings, Regulatory Approvals and other material documentation, in each case, (1) as in existence as of such date; (2) to the extent allowed under Applicable Law; and (3) to the extent pertaining to the Licensed Agents or Products, as such Licensed Agents or Products exists at such time (“Regulatory Materials”), and (B) will, and will cause its Affiliates to, take all reasonable steps necessary to transfer ownership of all such Regulatory Materials to Company, including submitting to each applicable Regulatory Authority a letter or other necessary documentation (with a copy to Company) notifying such Regulatory Authority of the transfer of such ownership of each Regulatory Approval within the Regulatory Materials, and will reasonably cooperate with Company to make the benefits of such Regulatory Materials available to Company or its designee(s); provided that, to the extent assignment pursuant to the preceding clause (A) is delayed or is not permitted by the applicable Regulatory Authority, Vertex will, and hereby does, grant, and will cause its Affiliates and any Sublicensee that does not elect to become a direct licensee of Company to grant, effective as of the effective date of termination, to Company a non-exclusive and irrevocable right of access and right of reference to such Regulatory Materials solely to Exploit Licensed Agents and Products;

(g)except with respect to any termination by Vertex under Section 9.2.3(a) and unless Company requests otherwise, effective upon such termination, Vertex hereby grants to Company (i) an exclusive, royalty-bearing, irrevocable, perpetual, license, which Company may sublicense through [***] tiers, under all Vertex Agreement Technology Controlled by Vertex or its Affiliates to Exploit Licensed Agents and Products in the Field in the Territory and (ii) a non-exclusive, royalty-bearing, irrevocable, perpetual, license, which Company may sublicense through [***] tiers, under all other Patents and Know-How Controlled by Vertex or its Affiliates that is necessary and has actually been used prior to such termination to Exploit Licensed Agents and Products in the Field in the Territory; provided that if the grant of such license to Company with respect to any Know-How or Patent included in the Vertex Agreement Technology or Company’s exercise of such license would trigger a royalty or other payment to a Third Party or would require compliance with any provision of any license between Vertex and a Third Party, Vertex will so notify Company in writing and such Know-How or Patent will only be included in the foregoing license if, following receipt of such notice, Company agrees in writing to reimburse Vertex for all such payments to such Third Party and comply with any such provision; and provided, further, that such license will not grant Company any rights with respect to any active ingredient in a Product that is not a Licensed Agent;

(h)solely in the event of termination by Vertex under Section 9.2.2 or 9.2.5, Company will pay to Vertex or its designated Affiliate the following royalty rates on Net Sales by Company, its Affiliates and, its and their (sub)licensees:

(i)In consideration for the license granted under the Vertex Agreement Technology in accordance with Section 9.6.2(g)(i), the royalty rates set forth in the following table:


Effective Date of Termination	Annual Net Sales (in Dollars) for all Products in the Territory	Royalty Rates as a Percentage (%) of Net Sales

	Portion of Annual Net Sales that exceeds $[*] up to and including $[*]	[***]%
	Portion of Annual Net Sales that exceeds $[***]	[***]%
[***]	Portion of Annual Net Sales up to and including $[***]	[***]%

(ii)In consideration for the license granted under other Patents and Know-How in accordance with Section 9.6.2(g)(ii), the Parties will negotiate economics at the time notice is given for such termination; provided that if the Parties are not able to resolve any dispute regarding such economics within [***] of the start of such negotiations, then such dispute will be escalated to the Executive Officers in accordance with Section 11.12.1 and, provided, further, that if the Executive Officers are unable to resolve such dispute within [***] (or such other period of time as mutually agreed by the Executive Officers), then such dispute will be resolved in accordance with Schedule 1.19.

The terms of Sections 1.117, 5.4.2, 5.4.3, 5.4.4, 5.4.5, 5.4.6, 5.9, 5.10 and 5.11 will apply with respect to Company’s payment of such royalty under this Section 9.6.2(h), mutatis mutandis. Notwithstanding the foregoing, the royalties set forth in this Section 9.6.2(h) will not apply if Company elects not to receive the license set forth in Section 9.6.2(g);

(i)except with respect to any termination by Vertex under Section 9.2.3(a), effective upon such termination, Company will have the right, but not the obligation, to purchase all of Vertex and its Affiliates’ remaining inventory of Licensed Agents and Products held as of the effective date of termination of this Agreement at a price equal to Vertex’s Manufacturing Cost;

(j)except with respect to any termination by Vertex under Section 9.2.3(a), effective upon such termination, Vertex hereby assigns to Company all of Vertex’s worldwide right, title and interest in and to any trademarks that is specific to and exclusively used for any Product (it being understood that the foregoing will not include any trademarks that contain the corporate or business name(s) or logo(s) of Vertex or any of its Affiliates or Sublicensees); and

(k)except with respect to any termination by Vertex under Section 9.2.3(a), upon Company’s request, Vertex agrees to discuss in good faith and reasonably cooperate with Company with respect to the assignment and transfer to Company of Vertex’s right, title and interest in and to any agreements between Vertex or any of its Affiliates and Third Parties that relate exclusively to the Development, Manufacture or Commercialization of any Licensed Agents or Products (including any Third Party licenses or sublicenses).

ARTICLE 11.
MISCELLANEOUS

1.1.Assignment. This Agreement will not be assignable by either Party to any Third Party without the written consent of the non-assigning Party. Notwithstanding the foregoing, either Party may assign this Agreement or its rights and obligations under this Agreement, without the written consent of the other Party, to an Affiliate or to 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; provided that such Affiliate or Third Party maintains the rights and abilities to perform the obligations of the assigning Party under this Agreement. The Parties agree that this Agreement and the Sublicense Agreement will always be assigned together to the same assignee; provided, however, that upon termination of the XXXX Agreement, the Sublicense Agreement may be assigned to XXXX pursuant to Section 8.6(a) of the XXXX Agreement. This Agreement will be binding upon the successors and permitted assigns of the Parties and the name of a Party appearing herein will be deemed to include the names of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement. Any assignment not in accordance with this Section 11.1 will be void. Notwithstanding anything to the contrary in this Agreement and subject to prior written notice by Company to Vertex, Company may sell, assign or otherwise transfer or pledge as a security all or any part of its rights to receive royalties and other related payments under this Agreement (collectively, “Rights”) without the prior consent of Vertex, and any permitted assignee, pledgee or other transferee of such Rights may likewise sell, assign or otherwise transfer or pledge as a security all or any part of such assignee, pledgee or other transferee’s Rights without the prior written consent of Vertex, and Company or such assignee, pledgee or other transferee may disclose Royalty Information in accordance with Section 10.8 as if such permitted assignee, pledgee or other transferee were Company.

1.2.Change of Control of Company.

Affiliates or its equity holders that could reasonably be expected to result in a Change of Control of Company.

If during the Term Company undergoes a Change of Control in accordance with Section 4.7, upon the effective date of such Change of Control (a) Vertex’s obligation to provide Company with Research reports in accordance with Section 2.1.10 and Development reports in accordance with Section 2.2.2 will terminate; and (b) Vertex will have the option to terminate Company’s participation in the JRC and decisions that would have been made by the JRC but for such termination will be made solely by Vertex.

1.3.Force Majeure. Each Party will be excused from the performance of its obligations under this Agreement to the extent that such performance is prevented by Force Majeure and the nonperforming Party promptly provides written notice of the Force Majeure to the other Party. Such excuse will continue for so long as the condition constituting a Force Majeure continues, on the condition that the nonperforming Party continues to use Commercially Reasonable Efforts to resume performance of its obligations under this Agreement.

1.4.Representation by Legal Counsel. Each Party hereto represents that it has been represented by legal counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof.

In any such event, this Agreement will be construed as if such clause of portion thereof had never been contained in this Agreement, and there will be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law.

1.9.Descriptive Headings. The descriptive headings of this Agreement are for convenience only and will be of no force or effect in construing or interpreting any of the provisions of this Agreement.

1.10.Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the United States of America or

other countries that may be imposed upon or related to Company or Vertex from time to time. Each Party agrees that it will not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate Governmental Authority.

1.11.Governing Law. This Agreement, and all claims arising under or in connection therewith, will be governed by and interpreted in accordance with the substantive laws of The Commonwealth of Massachusetts, without regard to conflict of law principles thereof.

1.12.Dispute Resolution. Subject to Section 11.12.4 regarding the resolution of certain Patent and Know-How-related disputes and Section 9.6.2(h)(ii) regarding post-termination royalty rates for economics related to certain intellectual property, if a dispute arises between the Parties in connection with or relating to this Agreement or any document or instrument delivered in connection herewith (a “Dispute”), it will be resolved pursuant to Sections 11.12.1, 11.12.2, and 11.12.3.

1.1.1.Escalation to Executive Officers. Either Party may refer any Dispute to the Executive Officers of the Parties, who will confer in good faith on the resolution of the issue, by delivering written notice to the other Party.

1.1.2.Mediation. If the Executive Officers are unable to agree on the resolution of any such Dispute within [***] (or such other period of time as mutually agreed by the Executive Officers) after such Dispute was first referred to them, then within [***] after the end of such [***] period or such other mutually-agreed period of time, either Party may serve notice to the other Party referring the matter to confidential mediation administered by the American Arbitration Association (“AAA”) under its Mediation Procedures (subject to this Section 11.12.2). Such mediation will begin within [***] following the service of such mediation notice.

If the Parties are unable to agree on a mediator within [***] after service of the mediation notice, a mediator will be appointed by the AAA. The mediation session will last for at least [***] before any Party has the option to withdraw from the process. The Parties may agree to continue the mediation process beyond [***], until there is a settlement agreement, or one Party or the mediator states that there is no reason to continue. The Parties agree to have their respective principals participate in the mediation process, including being present throughout the mediation session(s). Any period of limitations that would otherwise expire between the reference of the Disputes to the Executive Officers of the Parties and the conclusion of the mediation will be extended until [***] after the conclusion of mediation.

If the Dispute is not resolved through mediation, then either Party may by written notice to the other Party, elect to initiate an arbitration proceeding pursuant to the procedures set forth in Section 11.12.3 for purposes of having the matter settled (the “Arbitration Notice”).

1.1.3.Arbitration. A Party may elect to resolve any Dispute pursuant to arbitration only after the Parties have escalated the Dispute to the Executive Officers pursuant to Section 11.12.1 and attempted to mediate the Dispute pursuant to Section 11.12.2, which process will be a condition precedent to arbitration. The Parties will follow the following procedures to resolve such Dispute under arbitration:

(a)Binding Arbitration. Within [***] following a Party’s receipt of the Arbitration Notice, the Parties will submit such Dispute to, and such Dispute will be finally

resolved by, binding arbitration in accordance with the Commercial Arbitration Rules (the “Rules”) of the AAA by an arbitral tribunal composed of [***] impartial arbitrators bound by The Code of Ethics for Arbitrators in Commercial Disputes, all of whom will have relevant experience in the pharmaceutical industry (and the field of pharmaceutical development, commercialization or any other relevant area, as applicable), [***] appointed by each of the Parties within [***] after the Arbitration Notice, and the [***] who will chair the arbitral tribunal appointed by the Party-appointed arbitrators within [***] after the appointment of the [***] arbitrator, or, failing agreement by the Party-appointed arbitrators, by the AAA in accordance with the Rules. If, at the time of the arbitration, the Parties agree in writing to submit the Dispute to a single arbitrator, said single arbitrator will (i) have relevant experience in the pharmaceutical industry (and the field of pharmaceutical development, commercialization or any other relevant area, as applicable) and (ii) be appointed by agreement of the Parties within [***] after the Arbitration Notice, or, failing such agreement, by the AAA in accordance with the Rules. In no case will any arbitrator have participated in a prior mediation involving either Party unless explicitly agreed to by the Parties. Unless otherwise agreed by the Parties hereto, all such arbitration proceedings will be held in Boston, MA, U.S.A. All arbitration proceedings will be conducted in the English language. The Dispute will not be subject to the Commercial Arbitration Rules’ Expedited Procedures, regardless of the amount in controversy, unless otherwise agreed by the Parties in writing.

(b)Limited Discovery. Documentary discovery may be conducted at the discretion of the arbitrator(s); provided that any such discovery will (i) be limited to documents directly relating to the Dispute, (ii) be conducted pursuant to document discovery procedures as set forth under the laws of the International Bar Association Rules of Evidence, and (iii) be conducted subject to the schedule stipulated by the Parties, or in the absence of stipulation, the schedule ordered by the arbitrator(s). At the request of a Party, the arbitrator(s) may at their discretion order the deposition of witnesses. Depositions will be limited to a maximum of [***] depositions per Party, each of a maximum of [***] hours duration, unless the arbitrator(s) otherwise determine. Notwithstanding any provision of this Section 11.12.3 to the contrary, all discovery must be completed within [***] after the appointment of the arbitrator(s).

(a)Awards and Fees. The arbitrator(s) have the authority to make awards of declaratory relief and monetary damages, but they may not award damages excluded under Section 8.3, and will not under any circumstances have the authority or power to grant (i) equitable relief or (ii) orders for specific performance. The allocation of expenses of the arbitration, including reasonable attorney’s fees, will be determined by the arbitrator(s), or, in the absence of such determination, each Party will pay its own expenses, including attorney’s fees.

(b)Rulings. All arbitration proceedings must be completed within [***] after the Arbitration Notice. The Parties hereby agree that, subject to the provisions of this Section 11.12.3, the arbitrator(s) has authority to issue rulings and orders regarding all procedural and evidentiary matters that the arbitrator(s) deem reasonable and necessary with or without petition therefor by the Parties as well as the final award. The final award will be issued no more than [***] after the final submissions of the Parties, or as soon thereafter as practicable. All rulings by the arbitrator(s) will be final and binding on the Parties. The arbitrator(s) will issue a reasoned decision that accompanies the final award.

(c)Enforcement of Rulings by Courts of Competent Jurisdiction. Any ruling issued by the arbitrator(s) pursuant to Section 11.12.3(b) may be enforced, to the extent that such ruling complies with the provisions of Section 11.12.3(a), in any court having jurisdiction over any of the Parties or any of their respective assets.

(d)Confidentiality. All activities undertaken by the arbitrator(s) or the Parties pursuant to this Section 11.12.3 will be conducted subject to obligations of confidentiality no less restrictive than those set forth in ARTICLE 10. Further, the Parties acknowledge and agree that their respective conduct during the course of the arbitration, their respective statements and all information exchanged in connection with the arbitration, and the conduct of the arbitration and any information produced thereunder is Confidential Information under this Agreement and subject to the provisions of ARTICLE 10.

1.1.4.Patent and Know-How Disputes. Notwithstanding the foregoing in this Section 11.12, if a dispute arises between the Parties under this Agreement with respect to the interpretation, scope, validity, enforceability, applicability or term of any Patent or inventorship or ownership of any Know-How, then such dispute will not be resolved pursuant to Sections 11.12.1, 11.12.2 and 11.12.3, but instead may be brought by either Party in the federal courts of Massachusetts, in each case, (a) unless the Parties agree in writing to submit such claim to arbitration pursuant to Sections 11.12.1, 11.12.2 and 11.12.3 or (b) except to the extent federal jurisdiction cannot be maintained, in which case such claim will be submitted to arbitration pursuant to Sections 11.12.1, 11.12.2 and 11.12.3.

1.1.5.Equitable Relief. Notwithstanding the foregoing in this Section 11.12, nothing contained in this Agreement will in any way limit or preclude a Party from, at any time, seeking or obtaining equitable relief hereunder, whether preliminary or permanent, including a temporary or permanent restraining order, preliminary or permanent injunction, specific performance or any other form of equitable relief, from any United States court of competent jurisdiction if necessary to protect the interests of such Party. Each Party agrees that its unauthorized release of the other Party’s Confidential Information or its breach of Sections 4.5, 4.6, or 4.7 of this Agreement will cause irreparable damage to other Party for which recovery of damages would be inadequate, and that such other Party will be entitled to seek timely injunctive relief with respect to such breach, without the need to show irreparable harm or the inadequacy of monetary damages as a remedy, and without the requirement of having to post bond or other security, as well as any further relief that may be granted by a court of competent jurisdiction.

1.13.Entire Agreement. This Agreement constitutes and contains the complete, final and exclusive understanding and agreement of the Parties and cancels and supersedes all prior negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties respecting the subject matter hereof, including the CDA, which is hereby superseded and replaced in its entirety as of the Execution Date.

1.14.Independent Contractors. Both Parties are independent contractors under this Agreement. Nothing contained herein will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

1.15.Transparency Laws. Company agrees that Vertex may publicly disclose any information related to (a) any payment or transfer of value made to Company by Vertex hereunder, or (b) any payment or transfer of value made by Company to any Third Party or Affiliate in connection with this Agreement, in each case (a)-(b), to the extent reasonably required by Transparency Laws and by any means, including reporting through any government platform or system, Vertex’s and its Affiliates’ websites or any other platform or system. Company will promptly (and in any event within [***]) provide Vertex with any such information as reasonably requested by Vertex to enable compliance with Transparency Laws.

1.16.Interpretation. Except where the context expressly requires otherwise, (a) the use of any gender herein will be deemed to encompass references to either or both genders, and the use of the singular will be deemed to include the plural (and vice versa), (b) the words “include,” “includes” and “including” will be deemed to be followed by the phrase “without limitation,” (c) the word “will” will be construed to have the same meaning and effect as the word “shall,” (d) any definition of or reference to any agreement, instrument or other document herein will be construed as referring to such agreement, instrument or other document as from time to time amended, supplemented or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein), (e) any reference herein to any Person will be construed to include the Person’s successors and assigns, (f) the words “herein,” “hereof” and “hereunder,” and words of similar import, will be construed to refer to this Agreement in its entirety and not to any particular provision hereof, (g) all references herein to Sections, Schedules or Exhibits will be construed to refer to Sections, Schedules or Exhibits of this Agreement, and references to this Agreement include all Schedules and Exhibits hereto, (h) provisions that require that a Party, the Parties or any committee hereunder “agree,” “consent” or “approve” or the like will require that such agreement, consent or approval be specific and in writing, whether by written agreement, letter, approved minutes, e-mail or otherwise (but excluding text messaging or instant messaging), (i) references to any specific law, rule or regulation, or article, section or other division thereof, will be deemed to include the then-current amendments thereto or any replacement or successor law, rule or regulation thereof, (j) any action or occurrence deemed to be effective as of a particular date will be deemed to be effective as of 11:59 PM ET on such date and (k) the term “or” will be interpreted in the inclusive sense commonly associated with the term “and/or.”

1.17.No Third Party Rights or Obligations. No provision of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligations in any Person not a Party to this Agreement.

1.18.Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

1.19.Counterparts. This Agreement may be executed in two counterparts, each of which will be an original and both of which will constitute together the same document. Counterparts may be signed and delivered by digital transmission (e.g., .pdf), each of which will be binding when received by the applicable Party. The Parties may execute this Agreement by electronically transmitted signature and such electronically transmitted signature will be as effective as an original executed signature page.
