6.2.    Milestone Payments.

6.2.1.    Development & Regulatory Milestones. Vertex will pay Company the milestone payments set forth in this Section 6.2.1 in accordance with the procedure set forth in Section 6.2.3 upon the first achievement of the relevant milestone event by Vertex or any of its Affiliates or Sublicensees, which payments will be non-refundable, non-creditable and not subject to set-off. Each milestone payment set forth below is payable only once, regardless of the number of Products that achieve the relevant milestone event or the number of times a Product achieves the relevant milestone event. Unless this Agreement has been assigned to OSIF, Vertex will make a single payment to Company of a milestone payment specified in Section 5.3.1 of the Collaboration Agreement, which will satisfy Vertex’s obligations with respect to the applicable milestone under this Section 6.2.1 and with respect to the corresponding milestone under Section 5.3.1 of the Collaboration Agreement.

6.2.2.    Commercial Milestones. Vertex will pay Company the milestone payments set forth in this Section 6.2.2 in accordance with the procedure set forth in Section 6.2.3 upon the first achievement of the relevant milestone event by Vertex or its Affiliates or any Sublicensees, which payments will be non-refundable, non-creditable and not subject to set-off. Each milestone payment set forth below, is payable only once regardless of the number of Products that achieve the relevant milestone event or the number of times Product(s) achieve such milestone event. Unless this Agreement has been assigned to OSIF, Vertex will make a single payment to Company of a milestone payment specified in Section 5.3.2 of the Collaboration Agreement, which will satisfy Vertex’s obligations with respect to the applicable milestone under this Section 6.2.2 and with respect to the corresponding milestone under Section 5.3.2 of the Collaboration Agreement.

6.2.3.    Notice; Payment; Skipped Milestones. Vertex will provide Company with written notice upon the achievement of each of the milestone events set forth in Section 6.2.1 and Section 6.2.2, such written notice to be provided (a) with respect to any milestone event under Section 6.2.1, within [***] after such achievement and (b) with respect to any milestone event under Section 6.2.2, on or prior to the date of delivery of the royalty report under Section 6.3.7 for the [***] in which such milestone event is first achieved. Following receipt of such written notice, Company will promptly invoice Vertex for the applicable milestone and Vertex will make the appropriate milestone payment within [***] after receipt of such invoice. Each milestone payment corresponding with the milestones numbered [***] as set forth in Section 6.2.1 are intended to be successive; if a Product is not required to undergo the event associated with any such milestone event, such skipped milestone will be deemed to have been achieved upon the achievement by such Product of the next successive milestone event. Payment for any such skipped milestone that is owed in accordance with the provisions of the foregoing sentence with respect to a given Product will be due concurrently with the payment for the next successive milestone event by such Product, it being agreed that if a Product is not required to undergo the milestone numbered [***] the corresponding payment will be made upon the first to occur of the milestones numbered [***]. For the avoidance of doubt, the occurrence of milestone number [***] will not trigger payment of milestone number [***]. For clarity, each milestone payment corresponding with the milestones numbered [***] as set forth in Section 6.2.2 are intended to be additive such that if both milestones numbered [***] are achieved in the same Calendar Year, Vertex will pay to Company a payment of $[***] (which, unless this Agreement is assigned to OSIF, will be included in the amounts payable by Vertex to Company under the Collaboration Agreement).

6.3.    Royalties.

The obligation to pay royalties will be imposed only once with respect to the same unit of a Product.

6.3.2.    Royalty Term. Vertex will pay royalties to Company under this Section 6.3 on a Product-by-Product and a country-by-country basis during the Royalty Term for the applicable Product in the applicable country.

6.3.3.    Reduction for Lack of Patent Coverage and Regulatory Exclusivity. Subject to Section 6.3.6, if during any period within the applicable Royalty Term for a country, (a) no Valid Claim of an OSIF Patent exists that Covers such Product in such country, and (b) all applicable regulatory exclusivity periods, including data exclusivity periods, have expired in such country with respect to such Product, Net Sales of such Product in such country will be reduced by [***]% for purposes of calculating the royalty owed under Section 6.3.1 for the remainder of the Royalty Term.

6.3.4.    Reduction for Competition. Subject to Section 6.3.6, if during any [***] during the Royalty Term for a Product in a given country, (a) a Competitive Product with respect to such Product is sold during such [***] in such country and (b) Net Sales for such Product in such country is less than [***]% of the average Net Sales for such Product in such country during the [***] consecutive [***] immediately preceding the [***] during which any such Competitive Product is first sold in such country, then Net Sales of such Product in such country (after any applicable reduction pursuant to Section 6.3.3) will be reduced by [***]% for purposes of calculating the royalty owed under Section 6.3.1 for the remainder of the Royalty Term; provided, however, the royalty reduction in this Section 6.3.4 will no longer apply in any country, or in any [***] in a country, as applicable, where there are no Competitive Products for such Product marketed or sold in such country and the Net Sales of such Product sold by Vertex or its Affiliates or Sublicensees in such country during such [***] is greater than [***]% of the average Net Sales of such Product during the [***] consecutive [***] immediately prior to the [***] during which any such Competitive Product is first sold in such country.

6.3.5.    Third Party Licenses. Subject to Section 6.3.6, following the JRC’s (or the Parties’ if the JRC has disbanded) discussion of Vertex’s intent to enter into an agreement to license or acquire rights to Selected Third Party Intellectual Property, and if Vertex enters into such agreement, Vertex may deduct from the royalties payable to Company under this Section 6.3 [***]% of any Selected Third Party Intellectual Property Costs paid by Vertex, its Affiliates or Sublicensees.

6.3.6.    Aggregate Limitation on Deduction. Notwithstanding the foregoing, in no event will the deductions set forth in Section 6.3.3 through Section 6.3.5 reduce the royalties

payable to Company with respect to a particular [***] in a given country to less than [***]% of the royalties that would otherwise be due pursuant to Section 6.3.1; provided, that [***].

6.3.7.    Royalty Reports. Following the first sale of a Product giving rise to Net Sales and continuing for the remainder of the Royalty Term for such Product, within [***] after the end of each [***], Vertex will deliver a report to Company specifying on a Product-by-Product and country-by-country basis: (a) Net Sales in the relevant [***]; (b) to the extent such Net Sales include sales not denoted in US Dollars, a summary of the then-current exchange rate methodology(ies) used for the calculation of Net Sales in accordance with Section 6.5.2, and (c) royalties payable on such Net Sales, provided that Vertex will provide a good faith written estimate of such report under this Section 6.3.7 to Company within [***] after the end of each [***]. Unless this Agreement has been assigned to OSIF, then the royalty report submitted by Vertex under Section 5.4.7 of the Collaboration Agreement will satisfy Vertex’s obligations under both this Section 6.3.7 and Section 5.4.7 of the Collaboration Agreement. All royalty payments due under this Section 6.3 for each [***] will be due and payable within [***] after the end of each [***].

6.4.    OSIF Agreement. Vertex acknowledges that the OSIF Technology has been in-licensed by Company under the OSIF Agreement. All licenses and other rights granted to Vertex under this Agreement (including any sublicense rights) are subject to the rights and obligations of Company under the OSIF Agreement. Vertex acknowledges and agrees that it will comply with all the obligations under the OSIF Agreement to the extent applicable to Vertex as a sublicensee thereunder; provided that, [***]. Subject to Section 7.1.1, any payment obligations arising under the OSIF Agreement as a result of the Research, Development, Manufacture and Commercialization of a Product by or on behalf of Vertex under this Agreement will be paid solely by Company unless such payment obligations are resulted from the breach of the OSIF Agreement by Vertex.

6.5.    Payment Terms.

6.5.1.    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).

6.5.2.    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).

6.6.    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.

6.7.    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 [***]. Upon [***] prior written notice from Company, Vertex will permit an independent certified public accounting firm of internationally recognized standing, selected by Company and reasonably acceptable to Vertex, to examine the relevant books and records of Vertex and its Affiliates and Sublicensees, as may be reasonably necessary to verify the royalty reports submitted by Vertex in accordance with Section 6.3.7. An examination by Company under this Section 6.7 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; provided that Company may not exercise its audit right pursuant to this Section 6.7 in any [***] in which an audit has been conducted pursuant to Section 5.10 of the Collaboration Agreement. The accounting firm will be provided access to such books and records at Vertex’s facility or facilities where such books and records are normally kept and such examination will be conducted during Vertex’s normal business hours. Vertex 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 are correct or incorrect and the specific details concerning any discrepancies. No other information will be provided to Company. If the report or information submitted by Vertex 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 Company under this Section 6.7 will be borne by Company, unless such audit reveals an underpayment of amounts owed to or an overpayment of amounts owed by Company of more than [***] percent of the amount that was owed by Vertex or owed to Vertex, as applicable, with respect to the relevant period, in which case, Vertex will reimburse Company for the reasonable expense incurred by Company in connection with the audit.

6.8.    Payments under Agreement. Company acknowledges that Vertex has not participated in Company’s determination of the portion of payments made under the Collaboration Agreement that are attributable to the OSIF Technology and Vertex takes no position on Company’s determination of the portion of the payments set forth or described in Article 5 of the Collaboration Agreement that is attributable to the OSIF Technology.

Company will not cease paying costs for any OSIF Patent in a Major Market Country pursuant to Section 6.4 of the OSIF Agreement without the prior written consent of Vertex, not to be unreasonably withheld, conditioned, or delayed. With respect to OSIF Patents in countries other than Major Market Countries, if Company intends to cease paying costs for any such OSIF Patent pursuant to Section 6.4 of the OSIF Agreement, then Company will notify Vertex of such intention and give Vertex at least [***] to elect, upon written notice to Company, to pay for such costs. If Vertex does not make such election during such period, Company will be free to notify OSIF that it intends to cease paying for the applicable costs.

7.3.2.    Enforcement.

(a)    [***] will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding under any OSIF 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 7.3.1, or [***] if such Proceeding is an ANDA litigation, other than with respect to a request for a compulsory

(b)    [***] will have the first right, but not the obligation, to institute, prosecute, and control a Proceeding under any OSIF 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 7.3.1, 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 OSIF Platform Patents with respect to such Competitive Infringement.

(c)    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 [***].

7.9.    Unitary Patent System. The Party Prosecuting and Maintaining a Patent in Europe pursuant to Section 7.1 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.

Further, each Party agrees and acknowledges that all payments by Vertex to Company hereunder, other than the up-front fee pursuant to Section 6.1, royalty payments pursuant to Section 6.3, and the milestone payments pursuant to Section 6.2.1 and Section 6.2.2, do not constitute royalties within the meaning of Section 365(n) of the Bankruptcy Code or relate to licenses of intellectual property hereunder.

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 OSIF Technology and all information related to the OSIF 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:

(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.

9.1.1.    Indemnification by Vertex. Subject to Section 9.1.3, 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 9.1.2, as to such claim each Party will indemnify the other to the extent of their respective liability.

9.1.2.    Indemnification by Company. Subject to Section 9.1.3, 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 9.1.1, as to such claim each Party will indemnify the other to the extent of their respective liability.

9.1.3.    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 9.1.1 or 9.1.2, 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 9.1.1 or 9.1.2, 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 9.1) 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.

9.2.    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. In addition, Vertex will use commercially reasonable efforts to have OSIF, OSU and their respective Affiliates, officers, directors and employees named as additional insureds to its commercial general liability insurance. Each Party will furnish to the other Party evidence of such insurance upon request. Notwithstanding the foregoing, Vertex may self-insure to the extent that it self-insures for its other activities.

9.3.    Limitation of Consequential Damages. Except for (a) claims of a Third Party that are subject to indemnification under this ARTICLE 9, (b) claims arising out of a Party’s willful misconduct or intentional breach of this agreement or (c) any breach by a party of ARTICLE 11, neither Party nor any of its Affiliates will be liable to the other Party or its Affiliates for any incidental, consequential, special, punitive or other indirect damages or lost or imputed profits or royalties, whether liability is asserted in contract, tort (including negligence and strict product liability), indemnity or contribution, and irrespective of whether that Party or

any representative of that Party has been advised of, or otherwise might have anticipated the possibility of, any such loss or damage.

10.1.    Term; Expiration. Except with respect to the rights and obligations set forth in ARTICLE 2, which will become effective on the Execution Date, this Agreement is effective as of the Effective Date and, unless earlier terminated pursuant to the other provisions of this ARTICLE 10, will expire, in its entirety, upon the expiration of the last to expire Royalty Term under this Agreement with respect to all Products in all countries (such period, the “Term”):

10.2.    Termination of the Agreement.

10.2.1.    Termination of Collaboration Agreement. This Agreement will automatically terminate upon termination of the Collaboration Agreement in its entirety or as otherwise set forth in the Collaboration Agreement.

10.2.2.    Vertex’s Termination for Convenience. Vertex may terminate this Agreement (either in its entirety or on a Product-by-Product basis), for convenience by providing written notice of its intent to terminate to Company, in which case, such termination will be effective [***] after Company’s receipt of such written notice; except that if any termination under this Section 10.2.1 applies to a Product for which Vertex has received Marketing Approval, such termination will be effective [***] after Company’s receipt of such written notice.

10.2.3.    Termination for Material Breach.

(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 the breach is curable, Company will have [***] following its receipt of such written notice to cure such breach. 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 10.3; 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 terminate this Agreement or elect to exercise the alternate remedy provisions set forth in Section 10.3 on account of such breach will be suspended for so long as Company 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, Vertex will no longer have the right to terminate this Agreement or elect to exercise the alternate remedy provisions set forth in Section 10.3 on account of such breach.

(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.

10.2.4.    Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in Section 10.2.3 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 10.2.3, or the right to exercise the alternative remedy provisions of Section 10.3, as applicable, unless and until the relevant dispute has been resolved in accordance with Section 12.12. 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.

10.2.5.    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.

10.3.    Alternative Remedies to Termination. If Vertex has the right to terminate this Agreement pursuant to Section 10.2.3(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 6.2 by [***]% and royalty payments under Section 6.3 by [***]% (after giving effect to all other applicable deductions and credits available under such Section 6.3). 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 10.3, such remedy will be Vertex’s sole remedy for such breach.

10.4.    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 OSIF 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 10.4 (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 10.4 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.

10.5.    Consequences of Expiration or Termination of the Agreement.

10.5.1.    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 10, 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:

(a)    each Party will take all action required under Section 11.3 if requested by the other Party;

(b)    termination or expiration of this Agreement for any reason will be without prejudice to any rights or financial compensation that will have accrued to the benefit of a Party prior to such expiration or termination;

(c)    such expiration or termination will not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement; and

(d)    the following provisions of this Agreement will survive the expiration or termination of this Agreement: ARTICLE 1, Section 5.3, Sections 6.5 through 6.7 (inclusive, solely to the extent applicable and with respect to any amounts due prior to expiration or termination), Section 7.4 (with respect to proceedings to the extent relating to events occurring prior to the effective date of termination), Section 8.5, ARTICLE 9 (with respect to Section 9.2, for the time period set forth therein), this Section 10.5, Sections 11.1 through 11.5 (inclusive, for the time period set forth therein), and ARTICLE 12 (but not including Section 12.2).

10.5.2.    Early Termination. If this Agreement is terminated in its entirety or in part by a Party pursuant to Sections 10.2.1, 10.2.3, 10.2.5, or 10.4, 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 10.5.2(d), the applicable licenses granted by Company to Vertex with respect to such Product(s) in the Territory under this Agreement will terminate;

(b)    except as set forth in this Section 10.5, Vertex will have no further rights and Company will have no further obligations with respect to such Product(s) in the Territory;

(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; and

(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;

10.5.3.    Relationship to Collaboration Agreement. Neither Party will be permitted to terminate this Agreement, and Vertex will not be permitted to exercise its rights under Section 10.3, unless in each case the terminating Party (or Vertex in the case of Section 10.3) exercises the corresponding right under the Collaboration Agreement. For the avoidance of doubt, a material breach of the Collaboration Agreement will be deemed to be a material breach of this Agreement, and vice versa.

11.1.    Confidentiality. During the Term and for [***] thereafter, each Party (the “Receiving Party”) receiving any Confidential Information of the other Party (the “Disclosing Party”) hereunder will: (a) keep the Disclosing Party’s Confidential Information confidential; (b) not publish, or allow to be published, and will not otherwise disclose, or permit the disclosure of, the Disclosing Party’s Confidential Information; and (c) not use, or permit to be used, the Disclosing Party’s Confidential Information for any purpose, except, in each case, to the extent expressly permitted under this Agreement or the Collaboration Agreement (including, for clarity, to exercise any of its rights and perform any of its obligations) or otherwise agreed in writing. Without limiting the generality of the foregoing, to the extent that either Party provides the other Party any Confidential Information owned by any Third Party, the Receiving Party will handle such Confidential Information in accordance with the terms of this ARTICLE 11 applicable to a Receiving Party.

11.2.    Authorized Disclosure. Notwithstanding Section 11.1, each Party may disclose the other Party’s Confidential Information to the extent such disclosure is reasonably necessary to:

(a)    following discussion between the Parties of such disclosure through the IP Committee, file or prosecute patent applications as contemplated by this Agreement or the Collaboration Agreement;

(b)    subject to the remainder of this Section 11.2, prosecute or defend litigation;

(c)    exercise its rights and perform its obligations hereunder; provided that such disclosure is covered by terms of confidentiality similar to those set forth herein (except with respect to the duration of such terms which will be commercially reasonable under the circumstances);

(d)    subject to the remainder of this Section 11.2, its advisors (including financial advisors, attorneys and accountants), actual or potential acquisition partners, financing sources, investors, underwriters or sub(licensees) on a need to know basis; provided that such disclosure is covered by terms of confidentiality similar to those set forth herein (except with respect to the duration of such terms which will be commercially reasonable under the circumstances) which may include professional ethical obligations;

(e)    subject to the remainder of this Section 11.2, comply with Applicable Law; or

(f)    include such Confidential Information in Regulatory Filings.

In addition to the foregoing, each Party may disclose the other Party’s Confidential Information to Third Parties (other than an actual or potential competitor of such Party) in connection with its obligations under this Agreement or the Collaboration Agreement; provided that such disclosure is covered by terms of confidentiality similar to those set forth herein.

If a Party deems it reasonably necessary to disclose Confidential Information belonging to the other Party pursuant to Sections 11.2(b) or 11.2(e), the disclosing Party will, to the extent possible, give reasonable advance notice of such disclosure to the other Party and take reasonable measures to ensure confidential treatment of such information.

11.3.    Expiration or Termination of this Agreement. Following the expiration or termination of this Agreement, if requested by the Disclosing Party, the Receiving Party will return or destroy, at the Receiving Party’s election, all data, files, records and other materials containing or comprising the Disclosing Party’s Confidential Information, except to the extent such Confidential Information is necessary or useful to conduct surviving obligations or exercise surviving rights. Notwithstanding the foregoing, (a) the Receiving Party will be permitted to retain one copy of such data, files, records, and other materials for archival and legal compliance purposes and (b) the Receiving Party will not be required to delete or destroy any electronic back-up tapes or other electronic back-up files that have been created solely by the Receiving Party’s or its Affiliate’s automatic or routine archiving and back-up procedures, to the extent created and retained in a manner consistent with its or their standard archiving and back-up procedures.

11.4.    Applicable Law; SEC Filings and Other Disclosures. Either Party may disclose the terms of this Agreement or activities performed hereunder to the extent required to comply with Applicable Law, including the rules and regulations promulgated by the United States Securities and Exchange Commission or any equivalent governmental agency in any country in the Territory; provided that, to the extent such disclosure includes terms or information that have not previously been so disclosed, such Party will provide the other Party a reasonable opportunity to review such disclosure and reasonably consider the other Party’s comments regarding confidential treatment sought for such disclosure.

11.5.    [***]

12.1.    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 Collaboration Agreement will always be assigned together to the same assignee; provided, however, that upon termination of the OSIF Agreement, this Agreement may be assigned to OSIF pursuant to Section 8.6(a) of the OSIF 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 12.1 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 (as defined under the Collaboration Agreement) in accordance with Section 10.8 of the Collaboration Agreement as if such permitted assignee, pledgee or other transferee were Company.

12.2.    Change of Control of Company. Company will notify Vertex in writing promptly (and in any event within [***]) following the execution of a definitive agreement by Company, its Affiliates or its equity holders that could reasonably be expected to result in a Change of Control of Company.

12.3.    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.

12.4.    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 interpreting and applying the terms and provisions of this Agreement, no presumption will exist or be implied against the Party that drafted such terms and provisions.

12.5.    Notices. All written notices which are required or permitted hereunder will be in writing and sufficient if delivered personally or sent by nationally-recognized overnight courier, or through email to the applicable email address, addressed as follows:

Prior to any assignment of this Agreement to OSIF, all notice required under this Agreement will be deemed given if provided to Company for substantially the same purpose or pursuant to any corresponding Section under the Collaboration Agreement and in accordance with Section 11.5 thereof.

12.6.    Amendment. No amendment, modification or supplement of any provision of this Agreement will be valid or effective unless made in writing and signed by a duly authorized officer of each of Vertex and Company.

12.7.    Waiver. No provision of this Agreement will be waived by any act, omission or knowledge of a Party or its agents or employees except by an instrument in writing expressly waiving such provision and signed by a duly authorized officer of the waiving Party. The waiver

by either Party of any breach of any provision hereof by the other Party will not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself.

12.8.    Severability. If any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same will not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. 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.

12.9.    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.

12.10.    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.

12.11.    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.

12.12.    Dispute Resolution. Subject to Section 12.12.4 regarding the resolution of certain Patent and Know-How-related disputes, 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 12.12.1, 12.12.2, and 12.12.3.

12.12.1.    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.

12.12.2.    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 12.12.2). 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 12.12.3 for purposes of having the matter settled (the “Arbitration Notice”).

12.12.3.    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 12.12.1 and attempted to mediate the Dispute pursuant to Section 12.12.2, 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 12.12.3 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 9.3, 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 12.12.3, 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 12.12.3(b) may be enforced, to the extent that such ruling complies with the provisions of Section 12.12.3(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 12.12.3 will be conducted subject to obligations of confidentiality no less restrictive than those set forth in ARTICLE 11. 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 11.

12.12.4.    Patent and Know-How Disputes. Notwithstanding the foregoing in this Section 12.12, 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 12.12.1, 12.12.2 and 12.12.3, 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 12.12.1, 12.12.2 and 12.12.3 or (b) except to the extent federal jurisdiction cannot be maintained, in which case such claim will be submitted to arbitration pursuant to Sections 12.12.1, 12.12.2 and 12.12.3.

12.12.5.    Equitable Relief. Notwithstanding the foregoing in this Section 12.12, 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 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.

12.13.    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.

12.14.    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.

12.15.    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.
