Additional Product Development Teams, which shall also include [***] Vertex representatives, at Vertex’s option, may be established from time to time in connection with the development of additional Product Candidates. The PDT will be the principal organization through which the development of a Product Candidate is planned, administered, evaluated and completed, subject to appropriate review and approval at senior management levels as required by Merck from time to time. In addition to the Vertex representatives, the PDT will typically have members from the various Merck functional groups (e.g., research, preclinical, safety, clinical, regulatory, and marketing) which are or which will be expected to be involved in developing and obtaining regulatory approval for the Product Candidate and Product. Merck will appoint each PDT Chair. The PDT will be responsible for the preparation, implementation of the Development Plan (described below) with respect to each Product Candidate.

3.5.1 Development Plan. The PDT shall prepare and oversee the implementation of the overall Development Plan for each Product Candidate. The Development Plan shall, among other things, detail, schedule and fully describe the proposed toxicology studies, Clinical Trials, clinical material requirements for each Product Candidate, and will outline the key elements involved in obtaining Regulatory Approval in each Major Market. Vertex’s representatives on the PDT (or Vertex, if Vertex has no representative on the PDT) will receive all documents and information distributed or communicated to members to the PDT generally (or to any one or more members of the PDT in connection with the discharge of his or her duties on the PDT).

3.5.2 Development Responsibility and Costs. Merck shall have sole responsibility for, and bear the cost of implementing, the Development Plan with respect to each Product Candidate.

3.5.3 Regulatory Approvals. Merck shall be solely responsible for preparing and submitting registration dossiers for Regulatory Approval of Products in the Territory. All Regulatory Approvals shall be held by and in the name of Merck, and Merck shall own all submissions in connection

therewith. Merck shall have sole discretion as to the regulatory strategy and decision making for any Product Candidate or Product; provided, however, that Merck shall provide Vertex with an opportunity to review Merck’s general regulatory strategy and decision-making either by participating in the PDT or other approach mutually agreed-upon by the Parties.

3.6 Development Election. During the Research Program Term and the Washout Period, Merck shall have the exclusive right to select Compounds for further development and commercialization. The JRC will notify Merck each time a Compound meets the Development Candidate Criteria. The notice will be accompanied by the Development Information with respect to that Development Candidate. Merck may exercise its Development Election and accept the Development Candidate as a Product Candidate by delivery to Vertex, within [***] after receipt by Merck of the Development Information, of an exercise notice specifying the Development Candidate as to which the Development Election is being exercised. Notwithstanding the foregoing, if Merck shall at any time commence a Phase I Clinical Trial on a Compound without having formally exercised its Development Election, Merck shall be deemed to have exercised its Development Election with respect to such Compound.

3.7 Deferred Candidates. Any Development Candidate with respect to which Merck (1) elects not to accept as a Product Candidate; or (2) fails to exercise its Development Election within the [***] period referenced in Section 3.6, shall be a “Deferred Candidate.” If, during the Research Program Term, Merck ceases to be actively engaged in the development of a Product Candidate, Vertex may propose a Deferred Candidate to Merck for Development Election.

During the Research Program Term and Washout Period, Merck shall be entitled, in its sole discretion, to exercise its Development Election with respect to any (1) Compounds not previously presented to it as a Development Candidate; and (2) Deferred Candidates. Vertex shall not grant to any Third Party rights which are inconsistent with the grant of the Development Election to Merck under this Agreement. Upon expiration of the Research Program Term and Washout Period, the rights of the Parties with respect to any Compounds and Deferred Candidates shall be as set forth in Section 8.5 of this Agreement.

3.8 No Implied Licenses. Except as specifically set forth in this Agreement, neither Party shall acquire any license or other intellectual property interest, by implication or otherwise, in any Information disclosed to it under this Agreement or under any patents or patent applications owned or Controlled by the other Party or its Affiliates. In addition, Vertex shall not acquire any right, title or intellectual property interest to any Merck AK Compounds or Merck AK Patent Rights, except for such rights to financial compensation, if any, with respect to Merck AK Compounds in accordance with Section 2.8 and Article 5 of this Agreement.

3.8.1 To the extent it is contractually able to do so, Vertex agrees to review with Merck during the Research Program Term the potential for further collaboration directed to kinases studied by Vertex which are believed to have a potential role in oncology therapeutics.

3.9 Use of Vertex Logo. Where not prohibited by law or regulation, and subject to any required Regulatory Approval, which Merck shall use reasonable efforts to obtain, Vertex’s name and logo will be carried on all Product packaging, packaging inserts, labels, containers and printed material related thereto with a prominence substantially equivalent to that of Merck’s name and logo, provided, however that such requirement shall no longer apply in the event of a Change of Control of Vertex. Any trademark for a Product will be selected by, and will be the property of, Merck.

3.10 Supply of Bulk Drug Substance For Clinical Trials. Vertex shall promptly provide Merck with its existing inventory of clinical trial material for VX-680. Vertex shall also promptly provide Merck with Information in its possession relative to the manufacturing, formulation, and packaging of VX-680. Merck will be responsible for the manufacture of all bulk drug substance and clinical drug formulations of all Product Candidates, and for all manufacturing activities relating to the production, formulation and manufacture of commercial supplies of Products.

3.11 Co-Promotion by Vertex. Not less than [***] before the projected market introduction of any Product in a country within the Co-Promotion Territory, Vertex is entitled to give notice and propose to Merck, and Merck shall discuss in good faith with Vertex the feasibility of a co-promotion plan for Products on a fee-for-detail basis within the Co-Promotion Territory (including minimum co-promotion sales force size) and in accordance with the conditions set out in Schedule 3.11. If the Parties jointly decide to implement such a plan, Vertex and Merck shall initiate good faith negotiations and seek to enter into a mutually acceptable definitive written agreement (“Co-Promotion Agreement”) regarding Specialist Detailing (as described in Schedule 3.11) on a country-by-country basis no later than [***] before the projected market introduction of a Product in a country within the Co-Promotion Territory. Notwithstanding the foregoing, if Merck determines at the time of completion of [***] that earlier notice from Vertex of its intention to enter into a Co-Promotion Agreement would be desirable in order to optimally plan and execute a Product launch, the Parties will agree on a revised schedule for the negotiation and execution of the Co-Promotion Agreement consistent with the opinion of Merck’s regulatory experts about the anticipated Regulatory Authority review time for the corresponding NDA. Furthermore, if the Parties enter into a Co-Promotion Agreement on this revised schedule, the Parties recognize that Vertex [***], and Merck will take this into account in determining the minimum number of representatives Vertex will

provide at launch, [***] the Co-Promotion Agreement, in a timely manner as agreed to by both Parties.

3.11.1 The Co-Promotion Agreement shall be subject to the terms and conditions set forth in Schedule 3.11. In the event that Merck elects to outsource sales of any Product Candidate or Product in the Major Markets to a Third Party with which it does not have a pre-existing business relationship, it shall promptly inform Vertex of such election and shall negotiate in good faith with Vertex with respect to sales of such Product Candidate or Product.

The Party desiring to make any such public announcement shall provide the other Party with a written copy of the proposed announcement in sufficient time prior to public release to allow such other Party to comment upon such announcement, prior to public release.

In addition to the foregoing restrictions on public disclosure, if either Party concludes that a copy of this Agreement must be filed with the Securities and Exchange Commission, such Party shall provide the other Party with a copy of this Agreement showing any sections as to which the Party proposes to request confidential treatment, will provide the other Party with an opportunity and a reasonable time period to comment on any such proposal and to suggest additional portions of the Agreement for confidential treatment and will take such Party’s reasonable comments into consideration before filing the Agreement. If the filing Party disagrees with the other Party’s additional confidential treatment request, the Parties shall have an opportunity to discuss such matter in good faith before the Agreement is filed.

ARTICLE 5: PAYMENTS; ROYALTIES AND REPORTS

5.1 Research Program Funding. In consideration for Vertex’s performance of its obligations under the Research Program (including its FTE staffing obligations pursuant to Section 2.3), upon the terms and conditions contained herein, Merck shall pay Vertex:

(a) [***] for the period from the Effective Date through December 31, 2004, such payment to be made by Merck in two equal installments of [***], the first of which will be paid within [***] and the second of which will be paid [***]; and

(b) additional research support thereafter at an annual rate of [***] for the balance of the Research Program Term (the “Annual Research Fees”), such payments to be made in equal payments of US [***] per Calendar Quarter, payable in advance, with the first such quarterly payment due on or before [***].

The required payments are based upon the following assumptions: (a) the [***] of FTEs which Vertex will have employed in the Research Program for the portion of the Research Program that ends on [***] (the “Early Period”) will be [***]; (b) the [***] of FTEs which Vertex will have employed in the Research Program for the portion of the Research Program beginning on January 1, 2005 and ending upon the termination of the Research Program Term [***]; and (c) the annual rate per FTE is [***]. If the average FTE level for any of the Early Period, Calendar Year 2005, or the remainder of the Research Program Term after Calendar Year 2005 is less than the level specified above for that period (the difference being referred to in this section as an “FTE Shortfall”), then the amount of funding specified above for that period shall be reduced by an amount (the “FTE Shortfall Amount”) that bears the same relation to the total funding specified for that period as the FTE Shortfall bears to the projected FTE level for that period. The FTE Shortfall Amount shall be carried over from period to period and applied to compensate Vertex for FTE levels in subsequent periods that exceed the level for those periods as specified above. In any such subsequent period, Vertex shall be entitled to receive out of any remaining FTE Shortfall Amount a payment equal to the value (computed with reference to the FTE rate specified in (c) above) of any FTEs employed in the Research Period in excess of the FTE level specified above for such period.

5.2 Consideration for License. In consideration for the licenses granted pursuant to Article 3 and the research obligations set forth herein, upon the terms and conditions contained herein, Merck shall pay to Vertex a one-time payment of twenty million dollars (US $20,000,000) within five (5) business days of the Effective Date.

5.3 Milestone Payments. In addition to the payments set out in Sections 5.1 and 5.2, the following amounts (each, a “Milestone Payment”) shall be payable only once if (and only if) the corresponding milestones with regard to a Product are satisfied (each a “Milestone”):

(b) Once a Product achieves a Milestone for a particular Indication, it will be deemed to have achieved all earlier Milestones for such Indication, and any Milestone Payment for such earlier Milestone shall become due and payable to the extent it has not already been previously paid.

(d) Each Milestone Payment shall be payable upon achievement of such Milestone by action of any of Merck or a Related Party.

5.13 Royalties

5.13.1 Royalties Payable By Merck. Subject to the terms and conditions of this Agreement, Merck shall pay to Vertex royalties on a country-by-country basis as set out in this Section 5.13.

5.13.2 Patent Royalties

Subject to the provisions of this Agreement, including Section 5.13.3, Merck shall pay Vertex royalties in an amount equal to the following percentages of Net Sales of Products by Merck or its Related Parties, provided that the sale of Product would infringe a Valid Patent Claim in the country of sale:

·	For Calendar Year Net Sales in the Territory between []*:	[]*

·	For those incremental Calendar Year Net Sales in the Territory []*:	[]*

·	For those incremental Calendar Year Net Sales in the Territory greater than []*:	[]*

Royalties on each Product at the Patent royalty rates set forth above shall continue on a country-by-country basis until the later of (a) [***] from the date of First Commercial Sale of such Product in such country, or (b) the expiration of the last-to-expire Valid Patent Claim in effect in such country that would be infringed by the sale of such Product. This Section 5.13.2 shall apply to sales of Products in any country where such sale would infringe a Valid Patent Claim at any time, even if such Valid Patent Claim subsequently expires before the [***] of the date of First Commercial Sale of such Product in such country.

5.13.3 Know-How Royalty.

(a) If the sale of Product would infringe a Valid Patent Claim in the United States and at least [***] of the other Major Markets (i.e., [***]) (“Major Markets Condition”), in any countries where the sale of Product by Merck or its Related Parties would not infringe a Valid Patent Claim and royalties would not be due under Section 5.13.2 (each, a “Non-Patent Country”), Merck shall pay royalties to Vertex at the applicable royalty rate determined according to Section 5.13.2. Merck shall pay Vertex royalties at such rates for [***] from the date of First Commercial Sale of a Product in each such Non-Patent Country (the “Know-How License Term”), on a Product-by-Product and country-by-country basis. Notwithstanding the above, if at any time during the Know-How License Term applicable to a particular Non-Patent Country, a Third Party sells a pharmaceutical product which is a “generic version” of a Product being sold in that country (a “Third Party Product”) — where “generic version” means [***], the royalties payable to Vertex by Merck on Net Sales of such Product in such country for such period shall be [***] of the applicable royalty rate determined according to Section 5.13.2.

(b) Notwithstanding the provisions of Section 5.13.2, and except as set forth in Section 5.13.3(a), in countries where the sale of Product by Merck or its Related Parties would not infringe a Valid Patent Claim and royalties would not be payable under Section 5.13.2, Merck shall pay royalty rates that shall be set at [***] of the applicable royalty rate determined according to Section 5.13.2 (the “Know-How Royalty Rate”). Such royalties shall be calculated after first calculating royalties under Section 5.13.2. Merck shall pay Vertex royalties at the Know-How Royalty rate from the date of First Commercial Sale of a Product, for [***], on a Product-by-Product and country-by-country basis.

5.13.4 Royalty tiers pursuant to 5.13.2 and 5.13.3 shall be calculated based on Net Sales of each Product in the Territory, provided that the determination of whether the royalty shall be calculated under 5.13.2 or 5.13.3 shall be determined on a country-by-country basis. All royalties are subject to the following conditions:

(x) that only one royalty shall be due with respect to the same unit of Product;

(y) that no royalties shall be due upon the sale or other transfer among Merck or its Related Parties, but in such cases the royalty shall be due and calculated upon Merck’s or its Related Party’s Net Sales to the first independent Third Party; and

(z) no royalties shall accrue on the disposition of Product without consideration in reasonable quantities by Merck or its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies for a non-commercial purpose).

5.14 Change in Sales Practices. The Parties acknowledge that during the term of this Agreement, Merck’s sales practices for the marketing and distribution of Product may change to the extent that the calculation of the payment for royalties on Net Sales may become impractical or even impossible. In such event, the Parties agree to meet and discuss in good faith new ways of compensating Vertex to the extent currently contemplated under Section 5.13.

5.15 Royalties for Bulk Compound. In those cases where Merck sells bulk Compound rather than Product in packaged form to an independent Third Party, such sale shall be made in an arm’s length transaction and the royalty obligations of Section 5.13 shall be applicable to the bulk Compound.

5.16 Compulsory Licenses. If a compulsory license required under applicable law is granted to a Third Party with respect to Product in any country in the Territory

with a royalty rate lower than the royalty rate provided by Section 5.13, then the royalty rate to be paid by Merck on Net Sales in that country under Section 5.13 shall be reduced to the rate paid by the compulsory licensee.

5.17 Third Party Licenses. If one or more patent licenses from other Third Parties are required by Merck or its Related Parties in order to make, have made, use, offer to sell, sell or import Product Candidate or Product(s) (hereinafter “Third Party Patent Licenses”), or in the absence of such Third Party Patent License, the use by Merck of the Patent Rights, Vertex Know-How or Vertex Information and Inventions would infringe Third Party patents rights, then [***] of the consideration actually paid under such Third Party Patent Licenses by Merck or its Related Parties for sale of such Product in a country for a Calendar Quarter shall be creditable against the royalty payments due Vertex by Merck with respect to the sale of such Products in a country; provided, that the royalty payment to Vertex on account of sales in that country for such Calendar Quarter shall not be reduced by more than [***] the monies otherwise owed to Vertex; and any amounts not able to be reduced due to the immediately foregoing limitation shall be carried forward to future Calendar Quarters for crediting against future royalties in such country. [***]

5.18 Reports; Payment of Royalty. During the term of this Agreement following the First Commercial Sale of a Product, Merck shall furnish to Vertex a quarterly written report for the Calendar Quarter showing (i) the Net Sales of all Products subject to royalty payments sold by Merck and its Related Parties in the Territory during the reporting period; and (ii) the royalties payable under this Agreement. Reports shall be due on the [***] day following the close of each Calendar Quarter, although Merck shall use its commercially reasonable efforts to also provide Vertex with a “flash” report of estimated Net Sales, only, within [***] days after the end of each calendar month. Royalties shown to have accrued by each royalty report shall be due and payable on the date such royalty report is due. Merck shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined and to be verified by Vertex’s accounting firm pursuant to Section 5.19.

5.19 Audits. Upon the written request of Vertex and not more than once in each Calendar Year, Merck shall permit an independent certified public accounting firm of nationally recognized standing selected by Vertex and reasonably acceptable to Merck, at Vertex’s expense, to have access during normal business hours to such of the records of Merck as may be reasonably necessary to verify the accuracy of the royalty reports hereunder for any year ending not more than [***] prior to the date of such request. The accounting firm shall disclose to Vertex only whether the royalty reports are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to Vertex.

If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within [***] of the date Vertex delivers to Merck such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by Vertex.

Merck shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to Merck, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by Vertex’s independent accountant to the same extent required of Merck under this Agreement.

Upon the expiration of [***] following the end of any Calendar Year, the calculation of royalties payable with respect to such year shall be binding and conclusive upon Vertex, and Merck and its Related Parties shall be released from any liability or accountability with respect to royalties for such Calendar Year.

Vertex shall treat all financial information subject to review under this Section 5.19 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with Merck and/or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

5.20 Payment Exchange Rate. All payments to be made by Merck to Vertex under this Agreement shall be made in United States dollars and may be paid by check made to the order of Vertex or bank wire transfer in immediately available funds to such bank account in the United States designated in writing by Vertex from time to time. In the case of sales outside the United States, the rate of exchange to be used in computing the amount of currency equivalent in United States dollars due Vertex shall be made at the rate of exchange utilized by Merck in its worldwide accounting system, prevailing on the third to the last business day of the month prior to the month in which such sales are recorded by Merck.

5.21 Income Tax Withholding. If laws, rules or regulations require withholding of income taxes or other taxes imposed upon payments set forth in this Article 5, Merck shall make such withholding payments as required and subtract such withholding payments from the payments set forth in this Article 5. Merck shall submit appropriate proof of payment of the withholding taxes to Vertex within a reasonable period of time.

5.22 Interest Penalty. In case of any delay in payment by Merck to Vertex not occasioned by Force Majeure (as described in Section 9.3), interest at the monthly rate of [***], assessed from the thirty-first day after the due date of the payment, shall be due from Merck.

ARTICLE 7: PATENT PROVISIONS

7.1 Filing, Prosecution and Maintenance of Patents. Vertex agrees to file, prosecute and maintain in the Territory, upon appropriate consultation with Merck, the Patent Rights licensed to Merck under this Agreement. Merck shall have the first right to file, prosecute and maintain in the Territory Collaboration Patent Rights. With respect to Vertex Information and Inventions, Vertex may elect not to file, prosecute and maintain patent applications directly thereto and if so, Merck shall have the right to file, prosecute and maintain such patent applications. In such event, Vertex shall execute such documents and perform such acts at Vertex’s expense as may be reasonably necessary to effect an assignment of such Patent Rights to Merck in a timely manner to allow Merck to continue such preparation and prosecution or maintenance. In each case, the filing Party shall give the non-filing Party an opportunity to review the text of the application before filing, shall consult with the non-filing Party with respect thereto, and shall supply the non-filing Party with a copy of the application as filed, together with notice of its filing date and serial number. Vertex shall keep Merck advised of the status of the actual and prospective patent filings and upon the request of Merck, provide advance copies of any papers related to the filing, prosecution and maintenance of such patent filings. Vertex shall promptly give notice to Merck of the grant, lapse, revocation, surrender, invalidation or abandonment of any Patent Rights licensed to Merck for which Vertex is responsible for the filing, prosecution and maintenance. With respect to all filings hereunder, the filing Party shall be responsible for payment of all costs and expenses related to such filings.

7.2 Option to Prosecute and Maintain Patents.

(a) Merck Option. Vertex shall give notice to Merck of any desire to cease prosecution and/or maintenance of Patent Rights on a country by country basis in the Territory and, in such case, shall permit Merck, at its sole discretion, to continue prosecution or maintenance of such Patent Rights at its own expense. If Merck elects to continue prosecution or maintenance or to file based on Vertex’s election not to file pursuant to Section 7.1, Vertex shall execute such documents and perform such acts at Vertex’s expense as may be reasonably necessary to effect an assignment of such Patent Rights to Merck in a timely manner to allow Merck to continue such prosecution or maintenance. Any patents or patent applications so assigned shall not be considered Patent Rights.

(b) Vertex Option. Merck shall give notice to Vertex of any desire to cease prosecution and/or maintenance of Collaboration Patent Rights on a country by country basis in the Territory and, in such case, shall permit Vertex, at its sole discretion, to continue prosecution or maintenance of such Collaboration Patent Rights at its own expense. If Vertex elects to continue prosecution or maintenance or to file based on Merck’s election not to file pursuant to Section 7.1, Merck shall execute such documents and perform such acts at Merck’s expense as may be reasonably necessary to effect an assignment of such Collaboration Patent Rights to Vertex in a timely manner to allow Vertex to continue such prosecution or maintenance. Any patents or patent applications so assigned shall not be considered Collaboration Patent Rights.

7.3 Interference, Opposition, Reexamination and Reissue

7.3.1 Vertex shall, within ten (10) days of learning of such event, inform Merck of any request for, or filing or declaration of, any interference, opposition, or reexamination relating to Patent Rights. Merck and Vertex shall thereafter consult and cooperate fully to determine a course of action with respect to any such proceeding. Merck shall have the right to review and approve any submission to be made in connection with such proceeding.

7.3.2 Vertex shall not initiate any reexamination, interference or reissue proceeding relating to Patent Rights without the prior written consent of Merck, which consent shall not be unreasonably withheld.

7.3.3 In connection with any interference, opposition, reissue, or reexamination proceeding relating to Patent Rights and Collaboration Patent Rights, Merck and Vertex will cooperate fully and will provide each other with any information or assistance that either may reasonably request.

proceeding, including, to the extent permissible by law, consultation and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto.

7.3.4 Vertex shall bear the expense of any interference, opposition, reexamination, or reissue proceeding relating to Patent Rights. The Parties shall share equally the expense of any interference, opposition, reexamination or re-issue proceeding relating to the Collaboration Patent Rights.

7.4 Enforcement and Defense

7.4.1 Vertex shall give Merck notice of either (i) any infringement of Patent Rights, or (ii) any misappropriation or misuse of Vertex Know-How, that may come to Vertex’s attention. Merck and Vertex shall thereafter consult and cooperate fully to determine a course of action, including but not limited to the commencement of legal action by either or both Merck and Vertex, to terminate any infringement of Patent Rights or any misappropriation or misuse of Vertex Know-How. However, Vertex, upon notice to Merck, shall have the first right to initiate and prosecute such legal action at its own expense and in the name of Vertex and Merck, or to control the defense of any declaratory judgment action relating to Patent Rights or Vertex Know-How. Vertex shall promptly inform Merck if it elects not to exercise such first right and Merck shall thereafter have the right to either initiate and prosecute such action or to control the defense of such declaratory judgment action in the name of Merck and, if necessary, Vertex. Each Party shall have the right to be represented by counsel of its own choice.

7.4.2 If Vertex elects not to initiate and prosecute an action as provided in Section 7.4.1, and Merck elects to do so, the costs of any agreed-upon course of action to terminate infringement of Patent Rights or misappropriation or misuse of Vertex Know-How, including without limitation the costs of any legal action commenced or the defense of any declaratory judgment, shall be shared equally by Vertex and Merck.

7.4.3 For any action to terminate any infringement of Patent Rights or any misappropriation or misuse of Vertex Know-How, in the event that Merck is unable to initiate or prosecute such action solely in its own name, Vertex will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for Merck to initiate litigation to prosecute and maintain such action. In connection with any action, Merck and Vertex will cooperate fully and will provide each other with any information or assistance that either may reasonably request. Each Party shall keep the other informed of developments in any action or

proceeding, including, to the extent permissible by law, the consultation and approval of any settlement negotiations and the terms of any offer related thereto.

7.4.4 Any recovery obtained by either or both Merck and Vertex in connection with or as a result of any action contemplated by this Section, whether by settlement or otherwise, shall be shared in order as follows:

(i) the Party which initiated and prosecuted the action shall recoup all of its costs and expenses incurred in connection with the action;

(ii) the other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action; and

(iii) the amount of any recovery remaining shall then be allocated between the Parties on a pro rata basis taking into consideration the relative economic losses suffered by each Party.

7.4.5 Vertex shall inform Merck of any certification regarding any Patent Rights it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its successor provisions or any similar provisions in a country in the Territory other than the United States and shall provide Merck with a copy of such certification within five (5) days of receipt. Vertex’s and Merck’s rights with respect to the initiation and prosecution of any legal action as a result of such certification or any recovery obtained as a result of such legal action shall be as defined in subsections 7.4.1 through 7.4.4; provided, however, the Vertex shall exercise its first right to initiate and prosecute any action and shall inform Merck of such decision within ten (10) days of receipt of the certification, after which time Merck shall have the right to initiate and prosecute such action.

7.4.6 Patent Term Restoration. The Parties hereto shall cooperate with each other in obtaining patent term restoration or supplemental protection certificates or their equivalents in any country in the Territory where applicable to Patent Rights.
