The JRC shall meet formally at least quarterly, or with such other frequency, and at such time and location, as may be established by the Committee, for the following purposes: (i) To receive and review reports by VERTEX and its project teams, which shall be prepared and submitted to the JRC on a quarterly basis within fifteen (15) days after the end of each calendar quarter, such reports summarizing progress during the preceding quarter under the Research Plan; and to review information with respect to the Compounds under investigation (which VERTEX shall provide in form and content at least as extensive as customarily provided to the JRC under the Original Agreement); (ii) To review a proposal by either party that specified Excluded Compounds or Excluded Kinases be included in the Research Program, or that a Kinase be added to the list of Excluded Kinases; provided that the JRC shall have no authority to include or exclude any Compound or Kinase from the Research Program, and that any such action must be the subject of a formally adopted amendment to this Research Agreement; (iii) To define as soon as possible the further, more specific Development Criteria (x) for ongoing projects, after the signature of this Research Agreement, or (y) for new projects, after the start of such new research project; (iv) To review Development Candidates proposed by VERTEX and to assess whether a given Development Candidate proposed by VERTEX meets the Development Criteria; (v) To review the Research Plan and any proposed revisions thereto; (vi) [This subsection has been intentionally left blank.]; and (vii) To discuss matters relating to Patents, as may be presented to the JRC by VERTEX or NOVARTIS. The party hosting a particular JRC meeting shall prepare and deliver to the members of the JRC, within thirty (30) days after the date of each meeting, minutes of such First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 7 <Page> meeting setting forth, INTER ALIA, all decisions of the JRC, and including a report on the progress of work performed. In case the JRC meets by means of telephone or video conferences, this responsibility shall lie with VERTEX. 2.5.2. Decision-Making. (i) Each of VERTEX and NOVARTIS shall have one vote on the JRC. The objective of the JRC shall be to reach agreement by consensus on all matters within the scope of the Research Plan. However, in the event of a deadlock with respect to any action (which shall be deemed to have occurred if either party shall request a vote of the JRC on a matter and that vote shall either not be taken within thirty (30) days of the request or if taken shall result in a tie vote) and subject to the procedure set forth in subsection (ii) below as to certain matters, the vote of VERTEX, rendered after reasonable and open discussion among the members of the JRC, shall be final and controlling. (ii) Notwithstanding the foregoing, with respect to JRC decisions (x) as to the nature and extent of any additional Development Candidate Criteria referenced in Section 2.5.3 hereof, any disagreement between the parties that cannot be resolved within forty-five (45) days by the JRC (as that period may be extended under (iii) below) shall be referred to the JSC for resolution and if not resolved within seven (7) business days after referral, shall be referred for final resolution in good faith by the Chief Executive Officer of VERTEX and the Chief Executive Officer of NOVARTIS, and failing final resolution, there will be no change to the Development Candidate Criteria; or (y) as to whether or not Development Candidate Information provided by VERTEX, pursuant to subsection (iii) below, is complete or as to whether or not a given Compound proposed by VERTEX as a Development Candidate meets the Development Criteria, the matter shall be referred as provided in subsection (x) above to the JRC and the JSC and, failing agreement, the matter shall be referred for final resolution under the provisions of Section 11.2(b) of this Research Agreement. (iii) In the event that NOVARTIS's representatives on the JRC reasonably believe that the Development Candidate Information with respect to a particular Development Candidate proposed by VERTEX to the JRC is incomplete, NOVARTIS shall provide written notice thereof to VERTEX within fifteen (15) business days after receipt of the Development Candidate Information, and VERTEX shall undertake reasonable efforts to furnish the requested additional Development Candidate Information within fifteen (15) business days after receipt of NOVARTIS's notice hereunder. The 45-day period provided for action by the JRC under subsection (ii) above shall be extended by the amount of time required for VERTEX to provide the requested information, but in any event not in excess of thirty (30) days. (iv) Notwithstanding any of the foregoing, if VERTEX and NOVARTIS deadlock on any other matters being considered by the JRC which might have a significant impact on the time or likely success of the Research Program, the matter shall be referred to the JSC for resolution in accordance with Section 2.6 hereof. (v) Each party shall retain the rights, powers, and discretion granted to it under this Research Agreement, and the JRC shall not be delegated or vested with any such rights, powers or discretion except as expressly provided in this Research Agreement. First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 8 <Page> The JRC shall not have the power to amend or modify this Research Agreement, which may only be amended or modified as provided in Section 12.15. 2.5.3. ADDITIONAL DEVELOPMENT CANDIDATE CRITERIA. The parties acknowledge that it may be necessary or appropriate to adopt additional Development Candidate Criteria which more specifically define the pre-development characteristics of Compounds which the parties believe may be suitable for development and commercialization under the License Agreement, based upon the Kinase targeted by a specific project under the Research Program and the particular disease indication or indications thought to be addressed by Compounds modulating the Kinase which is the subject of that project. [***] Any disagreements with respect to the selection of additional Development Candidate Criteria hereunder will be addressed as provided in Section 2.5.2(ii). 2.6. JOINT STEERING COMMITTEE. 2.6.1. Composition and Purposes. VERTEX and NOVARTIS have established and will continue to participate in a Joint Steering Committee ("JSC") which shall consist of an equal number of senior executives as may be designated by each party from time to time. The JSC shall initially have four (4) members. If the JSC chooses to designate a Committee Chair, the Chair will be appointed from among the members of the JSC designated by NOVARTIS. The JSC shall meet annually, or with such other frequency, and at such time and location, as may be established by the Committee, for the following purposes: (i) General oversight of the entire collaboration between VERTEX and NOVARTIS, including the Research Program and any development and commercialization of a Drug Product Candidate under the License Agreement; (ii) Periodically review the overall goals and strategy of the Research Program; (iii) Discuss and attempt to resolve any deadlocked issues submitted to it by the JRC, although the vote of VERTEX's representatives shall prevail if the JSC is unable to reach a consensus on any matter other than matters submitted to the JSC under Section 2.5.2(ii). 2.7. EXCHANGE OF INFORMATION. 2.7.1. VERTEX, and at its sole discretion NOVARTIS, will share information with the JRC, as soon as it is available, necessary to facilitate mutual understanding of the status of the Research Program and decision-making in connection therewith. 2.7.2. Neither VERTEX nor NOVARTIS shall use Kinase Technology disclosed by the other party (excluding information which is no longer subject to confidentiality restrictions under Article V by reason of the exceptions set forth in Section 5.2) for any purpose, including the filing of patent applications containing such information, without the other party's consent, other than for carrying out the Research Program or discharging its responsibilities under the License Agreement, or as otherwise permitted under the Research Agreement or the License Agreement. 2.7.3.

SIGNATURE PAYMENT BY NOVARTIS. Upon the Effective Date of this Research Agreement NOVARTIS made an initial non-refundable payment of $15,000,000 to VERTEX. 3.2. STAFFING AND RESEARCH SUPPORT PAYMENTS. NOVARTIS has made or will make the payments specified below to VERTEX during each Research Year in support of the Research Program under this Research Agreement. The required payments are based upon the following assumptions: (a) the average number of FTE's which VERTEX will have employed in the Research Program during a Research Year will be approximately equal to the FTE Level listed in the third column below; and (b) the annual rate per FTE is approximately [***]. If the average FTE level for any Research Year is less than the level specified below for that year (the difference being referred to in this section as an "FTE Shortfall"), then the amount of funding specified below for that Research Year shall be reduced by an amount (the "FTE Shortfall Amount") which bears the same relation to the total funding specified below for that Research Year as the FTE Shortfall bears to the projected FTE Level for that Year. The FTE Shortfall Amount shall be carried over from year to year and applied to compensate VERTEX for FTE Levels in subsequent Research Years which exceed the level for those Years as specified below. In any such subsequent Research Year, VERTEX shall be entitled to receive out of any remaining FTE Shortfall Amount a payment equal to the value (computed with reference to the inflation-adjusted FTE rate specified above) of any FTE's actually employed during that Research Year in excess of the FTE Level specified for that year ("Excess FTE's"). Notwithstanding the foregoing, the FTE Shortfall Amount will not be applied to compensate VERTEX on account of more than 20 Excess FTE's in any one Research Year. <Table> <Caption> RESEARCH YEAR FUNDING FTE LEVEL 1 [***] [***] 2 [***] [***] 3 [***] [***] </Table> First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 10 <Page> <Table> <Caption> RESEARCH YEAR FUNDING FTE LEVEL 4 [***] [***] 5 [***] [***] 6 [***] [***] </Table> Research Year 1 will be deemed to have commenced on May 1, 2000. Payments due for each Research Year shall be made quarterly in advance on or before May 1, August 1, November 1 and February 1 of each Research Year except that the quarterly payment due May 1, 2000 was made within thirty business days after the Effective Date of this Research Agreement. All payments shall be made without deduction for withholding or other similar taxes, in United States dollars to the credit of such bank account as may be designated by VERTEX in writing to NOVARTIS. Any payments which fall due on a date which is a legal holiday in the Commonwealth of Massachusetts may be made on the next following day which is not a legal holiday in the Commonwealth. 3.3. DEVELOPMENT LOAN FACILITY. The existing development loan facility is hereby terminated. All currently outstanding loans made under the facility will be repaid by VERTEX on or before the earlier of: May 7, 2008, as specified in Section 3.3.3 of the Original Agreement; or the first anniversary of the effective date of any termination of this Research Agreement by NOVARTIS for cause under Section 9.2 hereof. Notwithstanding the foregoing, the provisions of Section 4.8 of this Research Agreement will apply as specified therein to repayment of development loans advanced on account of the Compounds known as VX-680 and VX-528. 3.4. RECORDS. VERTEX shall keep accurate records and books of accounts containing all data reasonably required for the calculation and verification of FTE's employed by VERTEX in the Research Program. At NOVARTIS's request, VERTEX shall make those records available, no more than once a year, during reasonable working hours, for review by a recognized independent accounting firm acceptable to both parties, at NOVARTIS's expense, for the sole purpose of verifying the accuracy of those records in the calculation of Research Program FTE's. VERTEX shall not, however, be required to retain or make available to NOVARTIS or its accountants, any such records or books of account for any Research Year, beyond thirty-six (36) months from the conclusion of that Research Year. NOVARTIS shall cause the accounting firm to retain all such information in confidence. In the event of a negative difference between the average number of FTE's stated to be involved in the Research Program and the number of FTE's actually employed, the amount previously advanced to VERTEX and attributable to any such negative difference shall be due and payable to NOVARTIS without delay. If the negative difference is more than [***] in any Research Year, then VERTEX shall also pay the reasonable costs of the independent accountant employed by NOVARTIS in the review. Interest at the rate of [***], assessed from the end of First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 11 <Page> the Research Year to which the negative difference relates, shall be due from VERTEX upon prior written notice. ARTICLE IV LICENSE, DEVELOPMENT AND COMMERCIALIZATION RIGHTS 4.1. DEVELOPMENT ELECTION. (a) NOVARTIS shall have the exclusive right (the "Development Election") to develop and commercialize, under the terms and conditions set forth in the License Agreement and for any and all Indications, (i) each Drug Product Candidate proposed to it by VERTEX as set forth below, and related Back-up Compounds as provided in Section 4.5 hereof and selected by NOVARTIS, and (ii) any Compound or Compounds selected by NOVARTIS, as provided in Section 4.1(d) hereof, from Compounds which have met the Development Candidate Criteria, whether or not any such Compound or Compounds have been proposed as Development Candidates by VERTEX. While the Development Election is in effect, VERTEX will not grant to any Third Party rights to VERTEX Kinase Technology which are inconsistent with the grant of the Development Election to NOVARTIS hereunder. NOVARTIS's right to exercise Development Elections will expire and NOVARTIS shall no longer have the right to select Drug Candidates hereunder upon the first to occur of: (1) The Final Termination Date as defined below; (2) Termination of the Research Program by VERTEX under Section 9.3 hereof; (3) Termination of the Research Program by either party hereto for Scientific Cause under Section 9.5 hereof. If NOVARTIS validly terminates the Research Program for cause under Section 9.2 hereof, the Development Election may nonetheless be exercised for the one-year period after the effective date of the termination for cause, but only with respect to Compounds which have met the Development Candidate Criteria prior to the effective termination date. (b) VERTEX shall notify NOVARTIS and the JRC each time VERTEX has identified a Compound that, in the reasonable exercise of its scientific and business judgment, is a suitable Development Candidate and meets the Development Candidate Criteria. The corresponding notice shall be accompanied by the Development Candidate Information relating to the Development Candidate and its Back-up Compounds, provided that information concerning Compound structures shall be handled as specified in Section 5.1 hereof. NOVARTIS may, at its sole discretion, exercise its Development Election and accept the Development Candidate as a Drug Product Candidate by delivery of written notice to VERTEX [***]. The total period of time from receipt of notice from VERTEX through [***] shall be referred to as the "Notice Period". Notwithstanding any other provisions of this Research Agreement, the Development Election with respect to any Development Candidate will not expire until the end of the Notice Period with respect to that Development Candidate. First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 12 <Page> (c) [This subsection has been intentionally left blank.] (d) VERTEX will submit a final report (the "Final Report") to NOVARTIS covering the period beginning on the Research Termination Date [***] (the "Final Report Period"). The Final Report will contain Development Candidate Information for any Compound that VERTEX believes, in the reasonable exercise of its scientific and business judgment, meets the Development Candidate Criteria [***], along with information with respect to relevant Back-up Compounds. The procedure whereby NOVARTIS may exercise its Development Election and accept any Development Candidate identified in the Final Report, for further development as a Drug Product Candidate, will be the same as that described in subsection (b) above, and the time period from receipt of the Final Report from VERTEX through the end of the 90-day period referenced in that subsection (b) shall be called the "Final Notice Period". In addition, [***] If NOVARTIS, based on this information, concludes that a given Compound does meet the Development Candidate Criteria, a formal Development Election procedure pursuant to Section 4.1(b) will be initiated for such Compound. If VERTEX disagrees with NOVARTIS's judgment that a given Compound meets the Development Candidate Criteria, the dispute resolution provisions in Section 2.5.2(ii) shall apply. The date upon which the Final Report Period, as and if extended by the parties as provided for in Section 4.3 hereof, expires shall be called the "Final Termination Date." (e) [***] (f) Promptly following exercise by NOVARTIS of its Development Election, the parties will execute a License Agreement substantially identical to the license agreement attached hereto as Exhibit A. NOVARTIS will develop and commercialize the Drug Product Candidate under the provisions of the License Agreement. If the Development Election has previously been exercised with respect to another Drug Product Candidate and a License Agreement is in effect, then the License Agreement will be amended to reflect the addition of another Drug Product Candidate. Development of each Drug Product Candidate shall proceed immediately after the Development Election is exercised, in accordance with the terms of the License Agreement. 4.2. [This section has been intentionally left blank.] 4.3. EXTENSION OF NOTICE PERIOD AND FINAL NOTICE PERIOD. NOVARTIS may propose to VERTEX by written notice delivered during [***] the Notice Period with respect to a particular Development Candidate, or the Final Notice Period, with specific reference to one or more Compounds included in the Final Report and meeting the Development Candidate Criteria, that the Notice Period or the Final Notice Period, as the case may be, for a specific Development Candidate or Compound be extended for good reason for a specified time to permit NOVARTIS, at its expense and under its direction, to conduct such additional studies of that Development Candidate or Compound as may be specified in the notice. VERTEX shall discuss this request with NOVARTIS and the parties shall attempt in First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 13 <Page> good faith to reach mutual agreement with respect to the requested extension period and the conduct of additional studies, but failing agreement the applicable Notice Period or Final Notice Period shall expire as specified herein. 4.4. REFUSED CANDIDATE. 4.4.1. If NOVARTIS does not exercise its Development Election within the Notice Period or the Final Notice Period, as applicable, specified in Section 4.1, with respect to a particular Development Candidate proposed by VERTEX, then the Development Election will expire with respect to that Development Candidate (a "Refused Candidate"), and (a) NOVARTIS will relinquish all rights under this Research Agreement and the License Agreement [***] (b) VERTEX may thereafter develop and commercialize the Refused Candidate and any such Excluded Compounds at its expense free of any further obligation to NOVARTIS with respect thereto; and [***], shall be considered Excluded Compounds under the provisions of this Section 4.4.1. 4.4.2. [This section has been intentionally left blank.] 4.5. BACK-UP COMPOUNDS. The following provisions will apply with respect to Back-up Compounds to any Drug Product Candidate. (a) VERTEX RESTRICTIONS ON NOMINATION AND DEVELOPMENT. So long as NOVARTIS is using commercially reasonable efforts with respect to the development of a particular Drug Product Candidate or the commercialization of a particular Drug Product, VERTEX will not (i) propose a Compound for development under the License Agreement which is a Back-up Compound with respect to that Drug Product Candidate or Drug Product, or (ii) until after the period starting on the date on which NOVARTIS has exercised its Development Election for a particular Drug Product Candidate and ending [***] (the "Lead Period"), commence development of that Back-up Compound either directly or together with or through an Affiliate or a Third Party. (b) TERMINATION OF DEVELOPMENT OR COMMERCIALIZATION. If, prior to the end of the Lead Period with respect to a particular Drug Product or Drug Product Candidate, NOVARTIS ceases to use commercially reasonable efforts to develop or commercialize that Drug Product Candidate or Drug Product, then the restrictions on nomination and development referenced in subsection (a) above will no longer apply with respect to Back-up Compounds for that Drug Product Candidate or Drug Product unless NOVARTIS, without delay, commences another Development Program under the License Agreement with another Compound (a "Replacement Candidate") targeting the same Kinase, which Replacement Candidate is a Back-up Compound associated with the discontinued Drug Product Candidate or Drug Product, and NOVARTIS shall have the right to select for this purpose any such Back-up Compound by providing VERTEX with notice of its Development Election in this regard. Any such Back-up Compound for which NOVARTIS has exercised its Development Election under this subsection (b) shall hereafter be a Drug Product Candidate subject to the terms and conditions of the License Agreement. First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 14 <Page> (c) TERMINATION OF RIGHTS TO BACK-UP COMPOUNDS. A Back-up Compound will no longer be subject to NOVARTIS's Development Election under the Research Agreement after the end of the Lead Period applicable to that Back-up Compound, except for Back-up Compounds which (i) subject to subsection (a) above, VERTEX has proposed for development on or before the Final Termination Date, and as to which NOVARTIS has exercised its Development Election hereunder; or (ii) have been or will be selected by NOVARTIS for development before the end of the applicable Lead Period under the provisions of subsection (b) above, or (iii) for which NOVARTIS has exercised or will exercise its Development Election before the end of the applicable Lead Period under the provisions of subsection (d) below. (d) NOVARTIS RIGHTS TO LICENSE BACK-UP COMPOUNDS. Anytime prior to the expiry of the Lead Period with respect a particular Drug Product Candidate, NOVARTIS may also, by paying in each case the Back-up Election Fee provided under Section 6.1 of the License Agreement, exercise its Development Election with respect to any one or more Back-up Compounds associated with that Drug Product Candidate, provided that Drug Product Candidate, or a Back-up Compound selected pursuant to the provisions of subsection (b) above, is still in active development. Any such Back-up Compound for which NOVARTIS has exercised its Development Election under this subsection (d) shall become a "Drug Product Candidate Back-up Candidate" subject to the terms and conditions of the License Agreement. (e) NOVARTIS OBLIGATIONS WITH RESPECT TO DRUG PRODUCT CANDIDATE BACK-UP CANDIDATES. So long as NOVARTIS is using commercially reasonable efforts, pursuant to the provisions of Sections 3.6 and 5.6 of the License Agreement, with respect to the development of a particular Drug Product Candidate or the commercialization of a particular Drug Product, NOVARTIS shall have no obligation to develop any of the Drug Product Candidate Back-up Candidates associated with that Drug Product Candidate or Drug Product. As soon as NOVARTIS ceases the development of a particular Drug Product Candidate, NOVARTIS's obligations to use diligent, commercially reasonable efforts will immediately shift from the discontinued Drug Product Candidate to an associated Drug Product Candidate Back-up Compound. If NOVARTIS ceases the development of a particular Drug Product Candidate and does not commence development of a Drug Product Candidate Back-up Compound pursuant to the foregoing, the license to the Drug Product Candidate and its Back-up Compounds under the License Agreement will expire and the license rights will revert to VERTEX. 4.6. [This section has been intentionally left blank.] 4.7. DRUG SUBSTANCE. As soon as practicable after the exercise of its Development Election with respect to a Drug Product Candidate, VERTEX will deliver to NOVARTIS, if so requested by NOVARTIS, all drug substance for that Candidate in VERTEX's possession, if any, to the extent it is usable in connection with development of that Candidate. NOVARTIS will reimburse VERTEX for the Manufacturing Cost (as such term is defined in the License Agreement) of that material within thirty (30) days of receipt of VERTEX's invoice therefor. 4.8. SPECIAL PROVISIONS REGARDING VX-680, VX-528 AND VX-608. First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 15 <Page> The parties acknowledge that VERTEX is currently pursuing three Development Candidates which have been designated as VX-608, VX-680 and VX-528. (a) VX-608. VX-608 will be governed by this Research Agreement and will be subject to the Development Election. The Notice Period with respect to VX-608 shall be deemed to have commenced on the later of (i) the date on which this Research Agreement is entered into, or (ii) the date by which NOVARTIS is in possession of the Development Candidate Information. If NOVARTIS exercises its Development Election with respect to VX-608 during the Notice Period, that Compound will become a Drug Product Candidate hereunder, and NOVARTIS will undertake all future development of VX-608 under the terms of the License Agreement. The Development Election Payment will be made to VERTEX and [***]. If NOVARTIS fails to exercise its Development Election with respect to VX-608 during the Notice Period, then VX-608 will become a Refused Candidate hereunder and the provisions of Section 4.4 will be applicable thereafter. Any outstanding development loan will be repaid in accordance with Section 3.3 hereof. (b) VX-680 AND VX-528. The Compounds designated by VERTEX as VX-680 and VX-528 are in early development under the provisions of the Original Agreement, and the terms of the Original Agreement shall continue to govern the rights and obligations of VERTEX and NOVARTIS with respect to VX-680 and VX-528 only, with the following modifications: [***] At its sole discretion exercisable by notice in writing from VERTEX to NOVARTIS delivered on or before [***], VERTEX may elect to consider VX-680 and VX-528 as Development Candidates which have become Refused Candidates under the Research Agreement, and the terms and conditions of the Research Agreement as they apply to any Refused Candidate shall thereafter apply in the case of VX-680 and VX-528. Contemporaneously with the aforementioned notice, VERTEX shall repay to NOVARTIS that portion of the total amount of any development loan previously advanced by NOVARTIS to VERTEX on account of either Compound, which is unspent and uncommitted as of the notice date. The balance of any development loan shall be repaid as provided in Section 3.3 hereof. ARTICLE V CONFIDENTIALITY 5.1. UNDERTAKING.

(b) 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. 5.4. SURVIVAL. The provisions of this Article V shall survive the termination of this Research Agreement and shall extend for a period of five (5) years thereafter. ARTICLE VI PUBLICATION Each of NOVARTIS and VERTEX reserves the right to publish or publicly present the results (the "Results") of the Research Program, subject to the following terms and conditions. The party proposing to publish or publicly present the Results (the "publishing party") will submit a draft of any proposed manuscript or speech to the other party (the "non-publishing party") for comments at least thirty (30) days prior to submission for publication or oral presentation. The non-publishing party shall notify the publishing party in writing within fifteen (15) days of receipt of such draft whether such draft contains (i) information of the non-publishing party which it considers to be confidential under the provisions of Article V hereof, (ii) information that if published would have an adverse effect on a patent application covering the subject matter of this Research Agreement which the non-publishing party intends to file, or (iii) information which the non-publishing party reasonably believes would be likely to have a material adverse impact on the development or commercialization of a Drug Product Candidate. In any such notification, the non-publishing party shall indicate with specificity its suggestions First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 18 <Page> regarding the manner and degree to which the publishing party may disclose such information. In the case of item (ii) above, the non-publishing party may request a delay and the publishing party shall delay such publication, for a period not exceeding ninety (90) days, to permit the timely preparation and filing of a patent application or an application for a certificate of invention on the information involved. In the case of item (i) above, no party may publish confidential information of the other party without its consent in violation of Article V of this Research Agreement. In the case of item (iii) above, if the publishing party shall disagree with the non-publishing party's assessment of the impact of the publication, then the issue shall be referred to the JSC for resolution. If the JSC is unable to reach agreement on the matter within thirty (30) days after such referral, the matter shall be referred by the JSC to the Chief Executive Officer of NOVARTIS and the Chief Executive Officer of VERTEX who shall attempt in good faith to reach a fair and equitable resolution of this disagreement. If the disagreement is not resolved in this manner within two (2) weeks of referral by the JSC as aforesaid, then the decision of the publishing party as to publication of any information generated by it, subject always to the confidentiality provisions of Article V hereof, shall be final, provided that such decision shall be exercised with reasonable regard for the interests of the non-publishing party. The parties agree that authorship of any publication will be determined based on the customary standards then being applied in the relevant scientific journal. The parties will use their best efforts to gain the right to review proposed publications relating to the subject matter of the Research Program by consultants or contractors. This Article VI shall terminate with the termination of this Research Agreement, but the provisions of Article V hereof shall continue to govern the disclosure by one party, whether by publication or otherwise, of Confidential Information of the other, during the period set forth in Section 5.4. ARTICLE VII INDEMNIFICATION 7.1. INDEMNIFICATION BY VERTEX. VERTEX will indemnify and hold NOVARTIS and its Affiliates, and their employees, officers and directors harmless against any loss, damages, action, suit, claim, demand, liability, expense, bodily injury, death or property damage (a "Loss"), that may be brought, instituted or arise against or be incurred by such persons to the extent such Loss is based on or arises out of: (a) the development, manufacture, use, sale, storage or handling of a Compound, a Development Candidate, a Drug Product Candidate or a Drug Product by VERTEX or its Affiliates or their representatives, agents, authorized sublicensees or subcontractors under this Research Agreement, or any actual or alleged violation of law resulting therefrom (with the exception of Losses based on infringement or misappropriation of intellectual property rights); or (b) the breach by VERTEX of any of its covenants, representations or warranties set forth in this Research Agreement; and First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 19 <Page> (c) provided however, that the foregoing indemnification shall not apply to any Loss to the extent such Loss is caused by the negligent or willful misconduct of NOVARTIS or its Affiliates. 7.2. INDEMNIFICATION BY NOVARTIS. NOVARTIS will indemnify and hold VERTEX, and its Affiliates, and their employees, officers and directors harmless against any Loss that may be brought, instituted or arise against or be incurred by such persons to the extent such Loss is based on or arises out of: (a) the development, manufacture, use, sale, storage or handling of a Compound, a Development Candidate, a Drug Product Candidate or a Drug Product by NOVARTIS or its Affiliates or their representatives, agents, authorized sublicensees or subcontractors under this Research Agreement, or any actual or alleged violation of law resulting therefrom (with the exception of Losses based on infringement or misappropriation of intellectual property rights); or (b) the breach by NOVARTIS of any of its covenants, representations or warranties set forth in this Research Agreement; and (c) provided that the foregoing indemnification shall not apply to any Loss to the extent such Loss is caused by the negligent or willful misconduct of VERTEX or its Affiliates. 7.3. CLAIMS PROCEDURES. Each Party entitled to be indemnified by the other Party (an "Indemnified Party") pursuant to Section 7.1 or 7.2 hereof shall give notice to the other Party (an "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any threatened or asserted claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided: (a) That counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such defense at such party's expense (unless (i) the employment of counsel by such Indemnified Party has been authorized by the Indemnifying Party; or (ii) the Indemnified Party shall have reasonably concluded that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in the defense of such action, in each of which cases the Indemnifying Party shall pay the reasonable fees and expenses of one law firm serving as counsel for the Indemnified Party, which law firm shall be subject to approval, not to be unreasonably withheld, by the Indemnifying Party); and (b) The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Research Agreement to the extent that the failure to give notice did not result in harm to the Indemnifying Party. (c) No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the approval of each Indemnified Party which approval shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement which (i) First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 20 <Page> would result in injunctive or other relief being imposed against the Indemnified Party; or (ii) does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (d) Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom. 7.4. COMPLIANCE. The parties shall comply fully with all applicable laws and regulations in connection with their respective activities under this Research Agreement. ARTICLE VIII PATENTABLE INVENTIONS 8.1. OWNERSHIP. All inventions made and all Know-How generated exclusively by either party or its Affiliates (directly or through others acting on its behalf) prior to and during the term of this Research Agreement shall be owned by the party making the invention or generating the Know-How claimed, or if such invention is made jointly (a "Joint Invention"), shall be owned jointly, all as determined in accordance with United States laws of inventorship. 8.2. PREPARATION. VERTEX shall take responsibility for the preparation, filing, prosecution and maintenance of all VERTEX Patents, and any patents and patent applications claiming Joint Inventions, and NOVARTIS shall take responsibility for the preparation, filing, prosecution and maintenance of all NOVARTIS Patents.

DISPUTE RESOLUTION PROCESS. First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 24 <Page> (a) General. Except as set forth in (b) below or as otherwise explicitly provided herein, in the event of any controversy or claim arising out of or relating to any provision of this Research Agreement, or the collaborative effort contemplated hereby, the parties shall, and either party may, initially refer such dispute to the JSC, and failing resolution of the controversy or claim within thirty (30) days after such referral, the matter shall be referred to the Chief Executive Officer of VERTEX and the Chief Executive Officer of NOVARTIS who shall, as soon as practicable, attempt in good faith to resolve the controversy or claim. If such controversy or claim is not resolved within sixty (60) days of the date of initial referral of the matter to the JSC, either party shall be free to initiate proceedings in any court having requisite jurisdiction. (b) Third Party Referral. Any dispute or claim relating to the "Referral Matters" as defined below which the parties are unable to resolve pursuant to the other dispute resolution mechanisms provided in this Research Agreement (other than litigation) shall, upon the written request of one party delivered to the other party, be submitted to and settled by a panel of Third Parties (a "Third Party Panel") appointed by VERTEX and NOVARTIS as provided below.

Each party will bear its own costs in the Third Party Referral process, and the parties will split equally the costs of the Third Party Panel members. The Third Party Panel will, upon the request of either party, issue its final determination in writing. ARTICLE XII MISCELLANEOUS PROVISIONS 12.1. OFFICIAL LANGUAGE. English shall be the official language of this Research Agreement and the License Agreement, and all communications between the parties hereto shall be conducted in that language. 12.2. WAIVER. No provision of this Research Agreement may be waived except in writing by both parties hereto. No failure or delay by either party hereto in exercising any right or remedy hereunder or under applicable law will operate as a waiver thereof, or a waiver of any right or remedy on any subsequent occasion. 12.3. FORCE MAJEURE. First Revised and Restated Research and Early Development Agreement -- Confidential -- Page 25 <Page> Neither party will be in breach hereof by reason of its delay in the performance of or failure to perform any of its obligations hereunder, if that delay or failure is caused by strikes, acts of God or the public enemy, riots, incendiaries, interference by civil or military authorities, compliance with governmental priorities for materials, or any fault beyond its control or without its fault or negligence. 12.4. SEVERABILITY. Should one or more provisions of this Research Agreement be or become invalid, then the parties hereto shall attempt to agree upon valid provisions in substitution for the invalid provisions, which in their economic effect come so close to the invalid provisions that it can be reasonably assumed that the parties would have accepted this Research Agreement with those new provisions. If the parties are unable to agree on such valid provisions, the invalidity of such one or more provisions of this Research Agreement shall nevertheless not affect the validity of the Agreement as a whole, unless the invalid provisions are of such essential importance for this Research Agreement that it may be reasonably presumed that the parties would not have entered into this Research Agreement without the invalid provisions. 12.5. GOVERNMENT ACTS. In the event that any act, regulation, directive, or law of a country or its government, including its departments, agencies or courts, should make impossible or prohibit, restrain, modify or limit any material act or obligation of NOVARTIS or VERTEX under this Research Agreement, the party, if any, not so affected, shall have the right, at its option, to suspend or terminate this Research Agreement as to such country, if good faith negotiations between the parties to make such modifications therein as may be necessary to fairly address the impact thereof, are not successful after a reasonable period of time in producing mutually acceptable modifications to this Research Agreement. 12.6. GOVERNMENT APPROVALS. Each party will obtain any government approval required in its country of domicile to enable this Research Agreement to become effective, or to enable any payment hereunder to be made, or any other obligation hereunder to be observed or performed.

This Research Agreement shall be binding upon and enforceable against the successor to or any permitted assignees from either of the parties hereto. 12.9. AFFILIATES. Each party may perform its obligations hereunder personally or through one or more Affiliates, although each party shall nonetheless be solely responsible for the performance of its Affiliates.

In that connection VERTEX at NOVARTIS' request shall sign a usual and customary exemption application and in addition shall apply for a tax refund at the request of NOVARTIS from any tax authority to which NOVARTIS has paid withholding tax on account of any payments made by NOVARTIS to VERTEX hereunder. ARTICLE VII BACK-UP COMPOUNDS Notwithstanding the provisions under the Research Agreement with respect to Back-up Compounds and for the sake of clarity, it is reminded that the parties agreed the following with respect to Back-up Compounds in Section 4.5 of the Research Agreement. 7.1 VERTEX RESTRICTIONS ON NOMINATION AND DEVELOPMENT. So long as NOVARTIS is using commercially reasonable efforts with respect to the development of a particular Drug Product Candidate or the commercialization of a particular Drug Product, pursuant to Sections 3.6 and 5.6 hereof, VERTEX will not (i) propose a Compound for development under the License Agreement which is a Back-up Compound with respect to that Drug Product Candidate or Drug Product, or (ii) until after the period starting on the date on which NOVARTIS has exercised its Development Election for a particular Drug Product Candidate and ending [***] (the "Lead Period"), commence development of that Back-up Compound either directly or together with or through an Affiliate or a Third Party. 7.2 TERMINATION OF DEVELOPMENT OR COMMERCIALIZATION. If, prior to the end of the Lead Period with respect to a particular Drug Product or Drug Product Candidate, pursuant to Sections 3.6 and 5.6 hereof, NOVARTIS ceases to use commercially reasonable efforts to develop or commercialize that Drug Product Candidate or Drug Product, then the restrictions on nomination and development referenced in Section 7.1 above will no longer apply with respect to Back-up Compounds for that Drug Product Candidate or Drug Product unless NOVARTIS, without delay, commences another Development Program under the License Agreement with another Compound (a "Replacement Candidate") targeting the same Kinase, which Replacement Candidate is a Back-up Compound License, Development and Commercialization Agreement -- Confidential -- Page 16 <Page> associated with the discontinued Drug Product Candidate or Drug Product, and NOVARTIS shall have the right to select for this purpose any such Back-up Compound by providing VERTEX with notice of its Development Election in this regard. Any such Back-up Compound for which NOVARTIS has exercised its Development Election under this Section 7.2 shall hereafter be a Drug Product Candidate subject to the terms and conditions of this Agreement. 7.3. TERMINATION OF RIGHTS TO BACK-UP COMPOUNDS. A Back-up Compound will no longer be subject to NOVARTIS' Development Election under the Research Agreement after the end of the Lead Period applicable to that Back-up Compound, except for Back-up Compounds which (i) subject to Section 7.1 above, VERTEX has proposed for development on or before the Final Termination Date, and as to which NOVARTIS has exercised its Development Election hereunder; or (ii) have been or will be selected by NOVARTIS for development before the end of the applicable Lead Period under the provisions of Section 7.2 above, or (iii) for which NOVARTIS has exercised or will exercise its Development Election before the end of the applicable Lead Period under the provisions of Section 7.4 below. 7.4 NOVARTIS RIGHTS TO LICENSE BACK-UP COMPOUNDS. Anytime prior to the expiry of the Lead Period with respect a particular Drug Product Candidate, NOVARTIS may also, by paying in each case the Back-up Election Fee provided under Section 6.1 of the this Agreement, exercise its Development Election with respect to any one or more Back-up Compounds associated with that Drug Product Candidate, provided that Drug Product Candidate, or a Back-up Compound selected pursuant to the provisions of Section 7.2 above, is still in active development. Any such Back-up Compound for which NOVARTIS has exercised its Development Election under Section 7.4 shall become a "Drug Product Candidate Back-up Candidate" subject to the terms and conditions of this Agreement. 7.5 NOVARTIS OBLIGATIONS WITH RESPECT TO DRUG PRODUCT CANDIDATE BACK-UP CANDIDATES. So long as NOVARTIS is using commercially reasonable efforts, pursuant to the provisions of Sections 3.6 and 5.6 of this Agreement, with respect to the development of a particular Drug Product Candidate or the commercialization of a particular Drug Product, NOVARTIS shall have no obligation to develop any of the Drug Product Candidate Back-up Candidates associated with that Drug Product Candidate or Drug Product. As soon as NOVARTIS ceases the development of a particular Drug Product Candidate, NOVARTIS' obligations to use diligent, commercially reasonable efforts will immediately shift from the discontinued Drug Product Candidate to an associated Drug Product Candidate Back-up Compound. If NOVARTIS ceases the development of a particular Drug Product Candidate and does not commence development of a Drug Product Candidate Back-up Compound pursuant to the foregoing, the license to the Drug Product Candidate and its Back-up Compounds under this Agreement will expire and the license rights will revert to VERTEX. License, Development and Commercialization Agreement -- Confidential -- Page 17 <Page> ARTICLE VIII INTELLECTUAL PROPERTY 8.1. PATENTABLE INVENTIONS AND KNOW-HOW. 8.1.1. Ownership. Any inventions made and all Know-How generated by either party or its Affiliates during the term of this Agreement, and Controlled by such party, relating to the manufacture or use of Bulk Drug Substance, a Drug Product Candidate or a Drug Product, or a prodrug thereof, will be disclosed to the other party promptly after the disclosing party recognizes the significance thereof.

NOVARTIS shall be responsible for the preparation, filing, prosecution and maintenance of all patents and patent applications included in NOVARTIS Patents. In each case the responsible party shall consult from time to time with the other party with respect thereto. VERTEX shall provide NOVARTIS with periodic reports listing the jurisdictions in which the VERTEX Patents licensed hereunder have been filed. Subject to the next succeeding sentences, VERTEX will file patent applications with respect to those VERTEX Patents in such other countries as NOVARTIS shall request in writing, all such other countries being countries in which NOVARTIS would customarily file its own cases dealing with similar subject matters. The party initially responsible for preparation, filing, prosecution and maintenance of a particular Patent (the "Initial Responsible Party") shall give thirty (30) days advance notice (the "Discontinuance Election") to the other party of any decision to cease preparation, filing, prosecution and maintenance of that Patent in any jurisdiction (a "Discontinued Patent"). In such case, the other party may elect at its sole discretion to continue preparation, filing and prosecution or maintenance of the Discontinued Patent at its sole expense. The party so continuing shall own any such Patent; and the Initial Responsible Party shall execute such documents and perform such acts as may be reasonably necessary for the other party to file or to continue prosecution or maintenance, including assigning ownership of such Patent to such electing party. Discontinuance may be on a country-by-country basis or for a patent application or patent series in total. Each party will consult the other party with respect to its choice of patent counsel and will keep that party continuously informed of all matters relating to the preparation, filing, prosecution and maintenance of Patents covered by this Agreement. Each party shall endeavor License, Development and Commercialization Agreement -- Confidential -- Page 18 <Page> in good faith to coordinate its efforts with those of the other party to minimize or avoid interference with the prosecution of the other party's patent applications. 8.1.3. Costs. Costs incurred in the preparation, prosecution and maintenance of Patents shall be borne by each party as set forth in Section 8.3 of the Research Agreement. 8.2. Infringement Claims by Third Parties. 8.2.1. Notice.

The notice shall set forth the facts of the Infringement Claim in reasonable detail. 8.2.2. Third Party Licenses. In the event that practicing the Technology in connection with the manufacture, use or sale of a Drug Product in any country would infringe a Third Party's patent, then VERTEX will use reasonable efforts to obtain a license under the Third Party's patents with a right to sublicense to NOVARTIS, under terms reasonably acceptable to both VERTEX and NOVARTIS, [***] 8.2.3. Discontinued Sales, License or Defense of Suit. If the required license is either unavailable or its terms are unacceptable both to VERTEX and to NOVARTIS, then NOVARTIS may elect in its sole discretion to discontinue sales of the Drug Product in such country or to undertake the defense of a patent infringement action or the prosecution of a declaratory judgment action with respect to the Third Party patents. [***] Provided that NOVARTIS is conducting the defense of the Infringement Claim or the prosecution of such declaratory judgment actions, [***]. The costs and expenses of all suits brought by a party under this Section 8.2.3 shall be reimbursed to such party and then to the other party, if it participates in such suit, PRO RATA, out of any damages or other monetary awards recovered therein in favor of VERTEX or NOVARTIS. [***] No settlement or consent judgment or other voluntary final disposition of a suit under this Section 8.2 may be entered into without the joint consent of VERTEX and NOVARTIS (which consent shall not be unreasonably withheld). 8.3. Infringement Claims Against Third Parties. 8.3.1. VERTEX and NOVARTIS each agree to take reasonable actions to protect their respective patents and technology from infringement and from unauthorized possession or use. 8.3.2. If any VERTEX Patents or NOVARTIS Patents are infringed or VERTEX Know-How or NOVARTIS Know-How is misappropriated, as the case may be, by a Third Party, the party to this Agreement first having knowledge of such infringement or misappropriation, or knowledge of a reasonable probability of such infringement or misappropriation, shall promptly notify the other in writing. The notice shall set forth the facts of such infringement or misappropriation in reasonable detail. The owner of the patent or technology, or VERTEX, in the case of joint ownership between the parties hereto, shall have the primary right, but not the obligation, to institute, prosecute, and control with its own counsel any action or proceeding with respect to infringement or misappropriation of such patent or technology and the other party shall have the right, at its own expense, to be represented in such action by its own counsel. If the License, Development and Commercialization Agreement -- Confidential -- Page 19 <Page> party having the primary right or responsibility to institute, prosecute, and control such action or prosecution fails to do so within a period of one hundred twenty (120) days after receiving notice of the infringement, the other party shall have the right to bring and control any such action by counsel of its own choice, and the other shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. If one party brings any such action or proceeding, the second party may be joined as a party plaintiff and, in case of joining, the second party agrees to give the first party reasonable assistance and authority to file and to prosecute such suit. The costs and expenses of all suits brought by a party under this Section 8.3.2 shall be reimbursed to such party and to the other party, if it participates in such suit, PRO RATA, out of any damages or other monetary awards recovered therein in favor of VERTEX or NOVARTIS.

NOTICE OF CERTIFICATION. VERTEX and NOVARTIS each shall immediately give notice to the other of any certification filed under the U.S. "Drug Price Competition and Patent Term Restoration Act of 1984" claiming that a VERTEX Patent or a NOVARTIS Patent is invalid or that any infringement will not arise from the manufacture, use or sale of any product by a third party. If VERTEX decides not to bring infringement proceedings against the entity making such a certification, VERTEX shall give notice to NOVARTIS of its decision not to bring suit within twenty-one (21) days after receipt of notice of such certification. NOVARTIS may then, but is not required to, bring suit against the party that filed the certification. Any suit by NOVARTIS or VERTEX shall either be in the name of NOVARTIS or in the name of VERTEX, or jointly by NOVARTIS and VERTEX, as may be required by law. For this purpose, the party not bringing suit shall execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the party bringing suit. 8.5. PATENT TERM EXTENSIONS. The parties shall cooperate in good faith with each other in gaining patent term extension wherever applicable to VERTEX Patents and NOVARTIS Patents covering Drug Product Candidates or Drug Products. NOVARTIS and VERTEX shall mutually determine which patents shall be extended. All filings for such extension shall be made by the party who owns the patent, provided, however, that in the event that the party who owns the patent elects not to file for an extension, such party shall (i) inform the other party of its intention not to file and (ii) grant the other party the right to file for such extension.

In the event that any act, regulation, directive, or law of a government, including its departments, agencies or courts, should make impossible or prohibit, restrain, modify or limit any material act or obligation of NOVARTIS or VERTEX under this Agreement, the party, if any, not so affected shall have the right, at its option, to suspend or terminate this Agreement as to such country, if good faith negotiations between the parties to make such modifications to this Agreement as may be necessary to fairly address the impact thereof, are not successful after a reasonable period of time in producing mutually acceptable modifications to this Agreement. License, Development and Commercialization Agreement -- Confidential -- Page 28 <Page> 15.7. GOVERNMENT APPROVALS. NOVARTIS will use reasonable efforts to obtain any government approval required to enable this Agreement to become effective, or to enable any payment hereunder to be made, or any other obligation hereunder to be observed or performed. Each party will keep the other informed of progress in obtaining any such approvals. 15.8. ASSIGNMENT. This Agreement may not be assigned or otherwise transferred by either party without the prior written consent of the other party; provided, however, that either party may assign this Agreement, without the consent of the other party, (i) to any of its Affiliates, if the assigning party guarantees the full performance of its Affiliates' obligations hereunder, or (ii) in connection with the transfer or sale of all or substantially all of its assets or business or in the event of its merger or consolidation with another company. Any purported assignment in contravention of this Section 15.8 shall, at the option of the non-assigning party, be null and void and of no effect.

This Agreement shall be binding upon and enforceable against the successor to or any permitted assignee from either of the parties hereto. 15.9. AFFILIATES. Each party may perform its obligations hereunder personally or through one or more Affiliates, although each party shall nonetheless be solely responsible for the performance of its Affiliates. Neither party shall permit any of its Affiliates to commit any act (including any act of omission) which such party is prohibited hereunder from committing directly. The use of subcontractors by either party shall not increase the financial obligations of the other party hereunder in any respect. 15.10. COUNTERPARTS. This Agreement may be executed in duplicate both of which shall be deemed to be originals, and both of which shall constitute one and the same Agreement. 15.11. NO AGENCY.

Notwithstanding any of the provisions of this Agreement, neither party shall at any time enter into, incur, or hold itself out to third parties as having authority to enter into or incur, on behalf of the other party, any commitment, expense, or liability whatsoever, and all contracts, expenses and liabilities undertaken or incurred by one party in connection with or relating to the development, manufacture or sale of Bulk Drug Substance, Drug Product Candidates or Drug Products shall be undertaken, incurred or paid exclusively by that party, and not as an agent or representative of the other party. 15.12.
