2.	MANAGEMENT OF COLLABORATION

2.1 General. For the purpose of this Article 2, EXEL and EPC shall be deemed collectively as one (1) “Party.”

(a)Role of Committees. Subject toSection 2.1(b) and the other terms and conditions of this Agreement, the Parties shall establish: (i) a joint executive committee (the “Joint Executive Committee” or “JEC”) that will oversee the Collaboration and facilitate communications between the Parties with respect to the Development, Regulatory Approval, and Commercialization of Committee-Governed Products hereunder; and (ii) three (3) specialized joint committees consisting of one to focus on each of the following areas arising out of the Collaboration: (A) Development and Regulatory Approval and other regulatory matters (such committee, the “Joint Development and Regulatory Committee” or “JDC”); (B) Commercialization (such committee, the “Joint Commercialization Committee” or “JCC”); and (C) financial issues (such committee, the “Joint Finance Committee” or “JFC”). Each Committee shall have the responsibilities and authority allocated to it in thisArticle 2 and elsewhere in this Agreement. It is contemplated that: (X) all significant matters (other than Party Implementation Matters, as defined inSection 2.6(c)(ii)) relating to the pre-clinical and clinical Development of Committee-Governed Products and the Commercialization of Co-Developed Products, in each case under this Agreement will be addressed by the applicable first-tier Committees (i.e., the JDC, the JCC, or the JFC) and, if appropriate, by the JEC, as contemplated bySection 2.6(c); and (Y) the Parties’ respective activities under this Agreement (including Party Implementation Matters) will be reported to the relevant Committees in a reasonable and appropriate level of detail. Each of the JDC, JCC, and the JFC shall provide, on a [*] basis (unless otherwise requested by the JEC), updates on its activities and achievements to the JEC for review and comment. The Parties intend that their respective organizations will work together to assure the success of the Collaboration.

(b)Limitations on the Authority of Committees. Notwithstanding the Committee structure established pursuant toSection 2.1(a) to oversee the Collaboration, each Party shall retain the rights, powers and discretion granted to it under this Agreement, and no such rights, powers, or discretion shall be delegated to or vested in a Committee unless such delegation or vesting of rights is expressly provided for in this Agreement or the Parties expressly so agree in writing. Without limiting the generality of the foregoing, no Committee shall have any authority or jurisdiction to: (i) amend, modify, or waive compliance with this Agreement, any of which shall require mutual written agreement of the Parties; (ii) interpret this Agreement, or determine whether or not a Party has met its diligence or other obligations under the Agreement or whether or not a breach of this Agreement has occurred; (iii) require EXEL to [*] (other than [*], [*] that are carried out in accordance with the [*], and any [*] obligations with respect to [*] that are set forth in the applicable [*]) without EXEL’s express written consent ([*]); (iv) require EXEL to [*] (other than [*], [*] that are carried out in accordance with [*], and any [*] with respect to [*] that are set forth in the applicable [*]) without EXEL’s express written consent (which [*]); (v) require BMS to [*] (other than [*]) without BMS’ express written consent (which [*]); (vi) make any decision on any matter that this Agreement expressly states is an option or election to be made by a Party; (vii) make any retroactive updates, amendments and modifications to, or waivers of provisions of, a Clinical Plan, an Annual Clinical Plan or an Approved Plan, any which shall require the mutual agreement of the Parties; and (viii) such other matters as are reserved to the consent, approval,

agreement or other decision-making authority of one or both Parties in this Agreement and that are not required by this Agreement to be considered by one or more Committees prior to the exercise of such consent, approval or other decision-making authority. For clarity, a Party’s right to cast a deciding vote on a matter in a Committee pursuant toArticle 2 shall not, in and of itself, subject such matter to the preceding sentence. Notwithstanding the foregoing, neither Party shall be restricted from bringing before any appropriate Committee for discussion any matter relating to the Collaboration that it believes warrants discussion between the Parties through the Committees, provided that the consideration of any such matter by any Committee shall not infringe or limit the exercise of a Party’s right of consent or approval or other decision-making authority granted to it by this Agreement nor shall any such consideration, as contemplated by this sentence, subject any such right of consent or approval or other decision-making authority to any dispute resolution mechanism provided for inSection 2.6(c) orArticle 14 or elsewhere in this Agreement.

(c)Discontinuation of Participation on a Committee.Each Committee shall continue to exist until the first to occur of: (i) the Parties mutually agreeing to disband the Committee, or (ii) a Party providing to the other Party written notice of its intention to disband and no longer participate in such Committee. Once one Party has provided the other Party written notice as referred to in subclause (ii) above, such Committee shall have no further obligations under this Agreement and such other Party receiving such notice shall have the right to solely decide, without consultation, any matters previously before such Committee, subject to the other terms of this Agreement.

(b)Responsibilities. The Alliance Managers shall use good faith efforts to attend all Committee meetings and support the co-chairpersons of each Committee in the discharge of their responsibilities. Alliance Managers shall be nonvoting participants in such Committee meetings, unless they are also appointed members of such Committee pursuant toSection 2.6(a). An Alliance Manager may bring any matter to the attention of any Committee if such Alliance Manager reasonably believes that such matter warrants such attention. Each Alliance Manager shall be charged with creating and maintaining a collaborative work environment within and among the Committees. In addition, each Alliance Manager: (i) will be the point of first referral in all matters of conflict resolution; (ii) will coordinate the relevant functional representatives of the Parties in developing and executing strategies and plans for the Products in an effort to ensure consistency and efficiency throughout the world; (iii) will provide a single point of communication for seeking consensus both internally within the respective Parties’ organizations and between the Parties regarding key strategy and plan issues; (iv) will identify and bring disputes to the attention of the appropriate Committee in a timely manner; (v) will plan and coordinate cooperative efforts and internal and external communications; and (vi) will take responsibility for ensuring that governance activities, such as the conduct of required Committee meetings and production of meeting minutes, occur as set forth in this Agreement, and that relevant action items resulting from such meetings are appropriately carried out or otherwise addressed.

2.8 Collaboration Guidelines.

(a)General. Each Party, in working with the other to Develop and Commercialize each Product and otherwise as set forth herein, shall assign responsibilities for the various operational aspects of the Collaboration to those portions of its organization that have the appropriate resources, expertise and responsibility for such functions and, consistent with this Agreement, treat each Product as if it were a proprietary product solely of its own organization. In all matters related to the Collaboration, the Parties shall strive to balance as best they can the legitimate interests and concerns of the Parties and to realize the full economic potential of each Product (taking into account the risks and costs of further Development and Commercialization).

(b)Independence. Subject to the terms of this Agreement, the activities and resources of each Party shall be managed by such Party, acting independently and in its individual capacity. The relationship between EXEL, EPC and BMS is that of independent contractors and none of the Parties shall have the power to bind or obligate any other Parties in any manner.

2.9 Overview of Accounting.

(a)Development Costs and Allowable Expenses. For purposes of determining Development Costs and Allowable Expenses, any expense allocated by either Party to a particular category under Development Costs for a Co-Developed Product, or Allowable Expenses for a Co-Developed Product, shall not be allocated to another category under Development Costs or Allowable Expenses (as applicable). Each Party agrees to determine such Development Costs and Allowable Expenses (as applicable) using its standard accounting procedures, consistently applied,

to the maximum extent practical as if such Co-Developed Product were a solely owned product of such Party, except as specifically provided in this Agreement. The Parties also recognize that such procedures may change from time to time and that any such changes may affect the definition of Development Costs or Allowable Expenses. The Parties agree that, where such changes are economically material to either Party, and consistent with GAAP, adjustments shall be made to compensate the affected Party to preserve the same economics as reflected under this Agreement under such Party’s accounting procedures in effect as of the date on which the activity in question (e.g., Development, Commercialization or Manufacturing) first commences under this Agreement. Where the change is or would be material to the other Party, the Party proposing to make the change shall provide the other Party with an explanation for the proposed change and an accounting of the effect of the change on the relevant expense category. Should the Parties disagree on the adjustment, the matter shall be placed before the JFC to resolve. Transfers between a Party and its Affiliates (or between its Affiliates) shall not have effect for purposes of calculating revenues, costs, profits, royalties or other payments or expenses under this Agreement.

(b)Affiliates. If either Party enters into any agreement with any of its Affiliates for the provision of materials or services pursuant to this Agreement, all costs incurred for the provision of such materials or services that are shared by the Parties under this Agreement shall be accounted for on the basis of the cost thereof to such Affiliate and not on the basis of any higher transfer price in effect between such Party and such Affiliate.

2.10Compliance with Law. Each Party hereby covenants and agrees to comply with applicable law in performing its activities connected with the Development, Manufacture and Commercialization (as applicable) of each Product.

2.11Records. Each of BMS and EXEL shall maintain complete and accurate records of all work conducted under the Collaboration and all results, data and developments made pursuant to its efforts under the Collaboration. Such records shall be complete and accurate and shall fully and properly reflect all work done and results achieved in the performance of the Collaboration in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes. Each of BMS and EXEL shall maintain such records for a period of [*] after such records are created;provided that the following records may be maintained for a longer period, in accordance with each such Party’s internal policies on record retention,provided that in no case shall such period be shorter than [*] from the date of creation of such records: (a) scientific notebooks; and (b) any other records that such other Party reasonably requests be retained in order to ensure the preservation, prosecution, maintenance or enforcement of intellectual property rights. Either such Party shall have the right to review and copy such records of the other Party at reasonable times to the extent [*] for it to conduct its obligations or enforce its rights under this Agreement.

2.12 Backup Programs.

(a)Commencement of a Backup Program. BMS and EXEL shall determine, via the JDC (or BMS shall determine, in the event that the JDC no longer exists), whether or not to commence a backup program with respect to each Collaboration Compound (namely, each of XL184 and XL281 taken as a whole) (each such program, a “Backup Program”), as well as the appropriate timing for such Backup Program(s). The Backup Program(s) shall be subject to JDC oversight and decision making and to one or more backup research plan(s) to be established by the

JDC prior to the start of backup work (the “Backup Research Plan”). In no event shall a Backup Program be designed to [*] targets other than the Identified Targets [*] with respect to a Collaboration Compound.

(b)Exelixis’ Conduct of Backup Programs. With respect to the Backup Program for any Collaboration Compound, EXEL shall have the first right to conduct such backup work up until the earlier of: (i) [*]; and (ii) [*] (the “Backup Program Trigger Date”). After the decision by the JDC (or BMS) to commence a Backup Program for a particular Collaboration Compound, EXEL shall promptly notify the JDC (or BMS) in writing whether EXEL will conduct such Backup Program. At a reasonable time prior to the Backup Program Trigger Date for a particular Backup Program, the JDC (or BMS) shall determine which Party (BMS or EXEL) shall continue the Development of Program Backups arising from such Backup Program; provided that EXEL shall have no further responsibilities with respect to a Backup Program for a Royalty-Bearing Product.

(c)BMS’ Conduct of Backup Programs. If EXEL notifies BMS that EXEL will not conduct a Backup Program for a particular Collaboration Compound, then BMS may conduct such Backup Program. EXEL will transition to BMS any [*] and other know-how then in EXEL’s possession and Control that are [*] for BMS to conduct such Backup Program.

(d) Costs of Backup Programs.

(i) The costs associated with any Backup Program for XL184 shall be shared by BMS and EXEL as follows: (A) if and for as long as any XL184 Product is a Co-Developed Product, any costs associated with such Backup Program shall be borne sixty-five percent (65%) by BMS and thirty-five percent (35%) by EXEL; and (B) if all XL184 Products are Royalty-Bearing Products, any costs associated with such Backup Program shall be borne one hundred percent (100%) by BMS. Notwithstanding the foregoing, in the case of subsection (A) above, in the event that [*], [*] shall bear [*] of the costs of the XL184 Backup Program until such costs reach [*] (such amount, the“[*] Backup Funding”). Such [*] Backup Funding shall not be deemed [*], except that, [*], then the future portion of the [*] Backup Funding [*] [*].

(ii) All costs associated with any Backup Program for XL281 incurred by either Party shall be borne [*].

(e)Reporting; Accounting.Reporting and accounting of shared costs for the Backup Programs shall be as set forth inSection 3.8(c)-(f) for Development Costs.

3.	DEVELOPMENT OF PRODUCTS

3.6Diligence of BMS. BMS shall use Diligent Efforts to Develop each XL184 Product and each XL281 Product in the U.S., including without limitation to carry out its responsibilities under the Annual Development Plan and the then-applicable Global Development Plan.

3.7 Limitations on Development. During the term of this Agreement, neither BMS nor EXEL nor any of its Affiliates shall, directly or through any Third Party, sponsor, conduct or cause to be conducted, otherwise assist in, supply any Co-Developed Product (or an XL281 Product in the case of EXEL) for use in connection with, or otherwise fund, any clinical trial or clinical study of such Product outside of the Global Development Plan or any Annual Development Plan, without the prior written consent of such other Party.

3.8 Development Costs.

(a)In general. Subject to the rest of thisSection 3.8(a)andSection 2.12(d), any Development Costs incurred by either BMS or EXEL for the Development of each Co-Developed Product shall be borne by BMS and EXEL as follows:

(i) EXEL shall bear the first One Hundred Million ($100,000,000) of all such Development Costs relating to XL184 (such amount, the“Exelixis Initial Funding Allocation”);

(ii)with respect to Development Costs associated with Co-Developed Products in excess of the Exelixis Initial Funding Allocation, BMS shall bear sixty-five percent (65%) of all such Development Costs, and EXEL shall bear thirty-five (35%) of all such Development Costs; and,

(iii) for clarity, all costs relating to Development activities undertaken solely for the purposes of seeking Regulatory Approval(s) of a Co-Developed Product in [*], shall be borne one hundred percent (100%) by BMS.

(b) Development Cost Deferral.

(i) If EXEL’s aggregate share of the Development Costs and Allowable Expenses for Co-Developed Products exceeds [*], then EXEL may elect to defer payment of its share of such Development Costs and Allowable Expenses that are in excess of [*] with respect to the Co-Developed Products in accordance with the remainder of thisSection 3.8(b). For clarity, BMS and EXEL agree that only [*] of the Exelixis Initial Funding Allocation for the conduct of Exelixis Clinical Trials shall count toward EXEL’s [*] threshold described in thisSection 3.8(b). EXEL’s deferral election may be made in writing anytime during the [*] following the end of the calendar quarter in which such excess first arises. If EXEL does not make such election, then EXEL would continue to pay its share of the Development Costs and Allowable Expenses with respect to the Co-Developed Product in accordance withSection 3.8(a),but subject to Section 3.8(b)(ii). If EXEL makes such election, then EXEL shall have no obligation to pay its share of such Development Costs and Allowable Expenses, to the extent such share exceeds [*] until the

first occurrence of the following: (A) the Launch in the U.S. of the first Co-Developed Product for [*]; (B) [*] the Launch in the U.S. of the first Co-Developed Product for [*]; or (C) [*] (the “Deferral End Point”). Until such Deferral End Point is reached, BMS shall bear one hundred percent (100%) of the Development Costs and Allowable Expenses with respect to such Co-Developed Product, and after such Deferral End Point is reached, EXEL and BMS shall again share the Development Costs and Allowable Expenses in accordance with the ratio set forth inSections 3.8(a) and 8.2, respectively.

(ii) If EXEL has not made a deferral election pursuant toSection 3.8(b)(i), and EXEL’s aggregate share of [*] Development Costs for Co-Developed Products in either calendar year [*] exceeds the greater of: (A) [*]; or (b) an amount equal to [*] of EXEL’s share of the [*] Development Costs that was budgeted for [*], as set forth in the initial Annual Development Plan created pursuant toSection 3.2(b), (the “[*] Cap”), then EXEL may elect to defer payment of its share of such Development Costs for [*] that are in excess of such [*] Cap with respect to the Co-Developed Products in accordance with the remainder of thisSection 3.8(b)(ii). The election by EXEL to defer such payment may be made in writing anytime during the [*] following the end of the calendar quarter in which such excess first arises. If EXEL does not make such election, then EXEL would continue to pay its share of the Development Costs with respect to the Co-Developed Product [*] in accordance withSection 3.8(a)unless EXEL makes a deferral election pursuant to Section 3.8(b)(i). If EXEL makes such election, then EXEL shall have no obligation to pay its share of such Development Costs [*], to the extent such share exceeds the [*] Cap for such calendar year, and [*], BMS shall bear one hundred percent (100%) of the Development Costs with respect to such Co-Developed Product.

(iii)Repayment of Deferred Costs.

(1) The amounts deferred pursuant toSection 3.8(b)(i) shall be referred to as the“Global Deferred Development Costs”. BMS shall have the right to credit an amount equal to [*] of the Global Deferred Development Costs (the“Development Cost Mechanism Amount”), as an offset: (A) against EXEL’s share of the Operating Profits from such Co-Developed Product, up to a maximum of [*] of such Operating Profits in any given quarter (in the case where EXEL has not exercised its Product Opt-Out for the Co-Developed Product); or (B) against royalties otherwise payable to EPC with respect to such Co-Developed Product, up to a maximum of [*] in any given quarter. Once the Development Cost Mechanism Amount is fully paid to BMS, Exelixis shall receive Operating Profits and royalties consistent withArticle 8.

(2) The amounts deferred pursuant toSection 3.8(b)(ii) shall be referred to as the“[*] Deferred Development Costs”. EXEL shall repay to BMS any [*] Deferred Development Costs with respect to [*] no later than [*], with interest accruing at a rate of [*]. Any failure by EXEL to repay any such [*] Deferred Development Costs shall be considered a breach of EXEL’s development funding obligations for purposes ofSection 11.3(b).

(c)FTE Records and Calculations; Adjustments to FTE Rate. Each of BMS and EXEL shall record and account for its FTE effort for the Development and Commercialization of the Co-Developed Product to the extent that such FTE efforts are included in Development Costs or Allowable Expenses that are, or may in the future be, shared under this Agreement, and shall report such FTE effort to the JDC on a quarterly basis. Except to the extent provided herein, each of

BMS and EXEL shall calculate and maintain records of FTE effort incurred by it in the same manner as used for other products developed by such Party. The JFC shall facilitate any reporting hereunder. The FTE rate shall initially be [*] and shall be adjusted annually, with each annual adjustment effective as of January 1 of each calendar year, with the first such annual adjustment to be made as of January 1, 2010, by mutual agreement of the JFC.

(d)Other Expenses.Any expenses incurred by BMS or EXEL for Development activities for the Co-Developed Product that do not fall within the definitions of Development Costs shall be borne solely by such Party unless the Parties determine otherwise.

(e)Reports and Payments for Development Costs. Prior to the commencement of each calendar quarter, each of BMS and EXEL shall prepare an estimate of its Development Costs for such quarter and shall deliver such estimate to the other Party. Upon receipt of such estimates by BMS and EXEL, the applicable Party shall make a reconciling payment to such other Party, within [*] subsequent to receipt of an invoice, to achieve the appropriate allocation of Development Costs provided for inSection 3.8(a)for such quarter, taking into account any differences between the prior quarter’s estimated Development Costs and the actual Development Costs incurred by the Parties. In addition, during the third (3^rd) month of each quarter, BMS and EXEL will provide an estimate of the total Development Costs incurred for the current calendar quarter. This estimate will contain two (2) months of actual costs and a third (3^rd) month of forecasted costs for the quarter. Each of BMS and EXEL shall report to the other Party within [*] after the end of each quarter with regard to the Development Costs actually incurred by it during such quarter for a Co-Developed Product, or as otherwise agreed by the JFC. Such report shall specify in reasonable detail (as agreed by the JFC) all expenses included in such Development Costs during such quarter and shall be accompanied by invoices, and/or such other appropriate supporting documentation as may be required by the JFC. Each of BMS and EXEL shall report to the other Development Costs incurred by it for comparison against such invoices and the Annual Development Plan, on a line item basis (e.g., budgeted FTE costs and actual out-of-pocket cost). BMS and EXEL shall seek to resolve any questions related to such accounting statements within [*] following receipt by each of BMS and EXEL of the other Party’s report hereunder. The JFC shall facilitate the reporting of Development Costs hereunder and the resolution of any questions concerning such reports. Each of BMS and EXEL shall have the right at reasonable times and upon reasonable prior notice to audit the other Party’s records as provided inSection 8.18 to confirm the accuracy of the other Party’s costs and reports with respect to Development Costs that are shared under this Agreement.

(f)Records. Each of BMS and EXEL shall keep detailed records of the Development Costs it incurs for the Co-Developed Product (and in the case of EXEL, including for the Exelixis Clinical Trials for XL184), including all supporting documentation for such expenses. Each of BMS and EXEL shall keep such records for at least [*] after the date that such expense was incurred.

3.9 Exelixis’ Opt-Out Rights.

3.11 Development of Royalty-Bearing Products

(a)Scope & Diligence. Except for the Exelixis Clinical Trials, BMS shall have sole control and responsibility for the Development, Manufacture (including formulation) and Commercialization of all Royalty-Bearing Products. BMS shall bear all costs and expenses associated with, the Development, Manufacture (including formulation) and Commercialization of all Royalty-Bearing Products. BMS shall use Diligent Efforts to Develop each such Royalty-Bearing Product in the Territory; provided that BMS may satisfy such obligation by sublicensing the development and commercialization of a Royalty-Bearing Product to a Third Party pursuant to the terms of this Agreement (and subject to EXEL’s ongoing activities with respect to Exelixis Clinical Trials). EXEL may notify BMS in writing if EXEL in good faith believes that BMS is not meeting its diligence obligations set forth in thisSection 3.11(a), and BMS and EXEL shall meet and discuss the matter in good faith. EXEL may further request review of BMS’ records generated and maintained as required underSection 3.11(c) below, to the extent those records relate to Development and Commercialization of a Royalty-Bearing Product.

(b)Reports and Payments for Royalty Bearing Development Expenses. Prior to the commencement of each calendar quarter for as long as EXEL is conducting Exelixis Clinical Trials or any other mutually agreed research or Development activities, in each case with respect to a Royalty Bearing Product, EXEL shall prepare an estimate of its costs and expenses associated with such conduct (such costs and expenses, the“Royalty Bearing Product Development Expenses”) for such quarter and shall deliver such estimate to BMS. Upon receipt of such estimates by EXEL, BMS shall make a reconciling payment to EXEL, within [*] subsequent to receipt of an invoice, taking into account any differences between EXEL’s estimated Royalty Bearing Product Development Expenses for the prior quarter and the actual Royalty Bearing Product Development Expenses incurred by EXEL for such quarter. In addition, during the third (3^rd) month of each quarter, EXEL will provide an estimate of the total Royalty Bearing Product Development Expenses incurred for the current calendar quarter. This estimate will contain two (2) months of actual costs and a third month of forecasted costs for the quarter. EXEL shall report to BMS within [*] after the end of each quarter with regard to the Royalty Bearing Product Development Expenses actually incurred by it during such quarter, or as otherwise agreed by the

JFC.

Promptly following receipt of such notice, BMS and EXEL shall meet and discuss in good faith and agree on an arbitrator to resolve the issue, which arbitrator shall be neutral and independent of both BMS and EXEL, shall have significant experience and expertise in trademark license agreements for pharmaceutical products, and shall have some experience in mediating or arbitrating issues relating to such agreements. If BMS and EXEL cannot agree on such arbitrator within [*] of request by either BMS or EXEL for arbitration, then such arbitrator shall be appointed by JAMS (formerly, the Judicial Arbitration and Mediation Service) (“JAMS”), which arbitrator must meet the foregoing criteria. Within [*] after an arbitrator is selected (or appointed, as the case may be), each of BMS and EXEL will deliver to both the arbitrator and the other Party a detailed written proposal setting forth its proposed terms for the Trademark License Agreement (the“Proposed Terms”of the Party) and a memorandum (the“Support Memorandum”) in support thereof, not exceeding ten (10) pages in length. BMS and EXEL will also provide the arbitrator a copy of this Agreement, as may be amended at such time. Within [*] after receipt of such other Party’s Proposed Terms and Support Memorandum, each of BMS and EXEL may submit to the arbitrator (with a copy to the other Party) a response to such other Party’s Support Memorandum, such response not exceeding five (5) pages in length. Neither BMS nor EXEL may have any other communications (either written or oral) with the arbitrator

other than for the sole purpose of engaging the arbitrator or as expressly permitted in thisSection 7.1(b)(i)(3); provided that, the arbitrator may convene a hearing if the arbitrator so chooses to ask questions of BMS and EXEL and hear oral argument and discussion regarding each of BMS’ and EXEL’s Proposed Terms. Within [*] after the arbitrator’s appointment, the arbitrator will select one of the two Proposed Terms (without modification) provided by BMS and EXEL that he or she believes is most consistent with the intention underlying and agreed principles set forth in this Agreement and most accurately reflects industry norms for a transaction of this type. The decision of the arbitrator shall be final, binding, and unappealable and BMS and EXEL shall promptly enter into a Trademark License Agreement having the terms set forth in the Proposed Terms selected by the arbitrator. For clarity, the arbitrator must select as the only method to determine the terms of the Trademark License Agreement one of the two sets of Proposed Terms, and may not combine elements of both Proposed Terms or take any other action. Except as expressly stated in thisSection 7.1(b)(i)(3), such arbitration shall be conducted in accordance with JAMS’ Streamlined Arbitration Rules and Procedures then in effect.

8.2Profit Sharing in the U.S.The terms and conditions of thisSection 8.2shall govern each Party’s rights and obligations with respect to Operating Profits (or Losses) relating to each Co-Developed Product in the U.S. For clarity, Exelixis shall have no right to share Operating Profits, and, except as set forth inSection 8.3(a)(iii) below, no obligation to bear any Operating Losses, in each case pursuant to thisSection 8.2, with respect to (x) any Royalty-Bearing Product in the U.S.; or (y) any Product in the Royalty Territory, and in each case Exelixis shall instead be entitled to receive from BMS royalties pursuant toSection 8.5.

(a)Basic Concept. The Parties shall share equally all Operating Profits and all Operating Losses (as applicable) for each Co-Developed Product in the U.S. Specifically, the Net Sales of such Product in the U.S. shall be allocated first to reimburse each Party for fifty percent (50%) of its Allowable Expenses for such Product in the U.S., and any remaining sums, shall be Operating Profit or Operating Loss (as applicable), which shall be shared fifty percent (50%) by each Party. The JFC will determine future financial flows regarding the sharing of Operating Profits and Allowable Expenses consistent with the first sentence of thisSection 8.2(a)and with each Party’s then existing tax and transfer pricing policies.

(b) [*]. If Exelixis elects [*] Co-Developed Product (a “[*]”), then, solely during the period in which BMS is actually promoting such Product [*], BMS shall receive [*] (such [*], the “[*]”) of Operating Profits (or Losses) for such Product (resulting in [*] for such Product to [*] during such period). The Parties agree that the Co-Promotion Agreement shall contain a mechanism by which the Parties shall [*]. The Co-Promotion Agreement shall also contain a mechanism, similar to that described inSection 8.11(b), for arbitrating any disputes if the Parties are unable to mutually agree on [*] for such Product.

(c)Commercialization Overruns. If the Allowable Expenses for Commercialization activities exceed the amounts budgeted for all such activities in the applicable Annual Commercialization Plan (and taking into account any amendments to such Annual Commercialization Plan and Budget that may be approved during a calendar year) by more than [*] (calculated for all costs incurred over such calendar year for all budgeted activities), such excess Allowable Expenses (each, a“Commercialization Overrun”) shall be borne by [*] and such excess Allowable Expenses shall be [*]. Notwithstanding the foregoing, in the event and to the extent that such Commercialization Overrun was [*], or did not [*], then such Commercialization Overrun shall be [*], as the case may be.

8.3 Calculation and Payment of Profit or Loss Share.

(a)Reports and Payments in General. With respect to each Co-Developed Product, each Party shall report to the other Party, within [*] after the end of each quarter, with regard to Net Sales and Allowable Expenses incurred by such Party (including any Allowable Expenses incurred by a Party prior to Regulatory Approval of such Product) for such Product during such quarter in the U.S.Each such report shall specify in reasonable detail all deductions allowed in the calculation of such Net Sales and all expenses included in Allowable Expenses, and, if requested by a Party, any invoices or other supporting documentation for any payments to a Third Party that individually exceed [*] (or such other amount approved by the JFC) shall be promptly provided. Within [*] after the end of each quarter (or for the last quarter in a year, [*] after the end of such quarter), the Parties shall reconcile all Net Sales and Allowable Expenses to ascertain

whether there is an Operating Profit or an Operating Loss and payments shall be made as set forth in paragraphs (i) and (ii) below, as applicable.

(i) If there is an Operating Profit for such quarter, then BMS shall reimburse Exelixis for Allowable Expenses incurred by Exelixis in such quarter and shall pay to Exelixis, subject toSections 3.8(b) and 8.2(b), an amount equal to fifty percent (50%) of the Operating Profit for such quarter; or

(ii) If there is an Operating Loss for such quarter, then, subject toSection 3.8(b), the Party that has borne less than its share of the Operating Loss in such quarter shall make a reconciling payment to the other Party to assure that each Party bears its share of such Operating Loss during such quarter.

(iii) In the event that Exelixis has borne Allowable Expenses, or has made reconciling payments to BMS relating to Allowable Expenses pursuant to clause (ii) above, with respect to a Co-Developed Product which becomes a Royalty-Bearing Product, then BMS shall reimburse Exelixis for such Allowable Expenses during the calendar quarter in which such Co-Developed Product becomes a Royalty-Bearing Product.

(b)Last Calendar Quarter. No separate payment shall be made for the last quarter in any year. Instead, at the end of each such year, a final reconciliation shall be conducted by comparing the share of Operating Profit (or Loss) to which a Party is otherwise entitled for such year pursuant toSection 8.2 against the sum of all amounts (if any) previously paid or retained by such Party for prior quarters during such year, and the Parties shall make reconciling payments to one another no later than [*] after the end of such quarter, if and as necessary to ensure that each Party receives for such year its share of Operating Profits and bears its share of Operating Losses in accordance withSection 8.2.

8.15Sublicenses. In the event BMS grants any permitted licenses or sublicenses to Third Parties to sell Products that are subject to royalty payments underSection 8.5, BMS shall have the responsibility to account for and report sales of any Product by a licensee or a sublicensee on the same basis as if such sales were Net Sales by BMS. BMS shall pay to EPC (or cause the licensee or sublicensee to pay to EPC, with BMS remaining responsible for any failure of the licensee or sublicensee to pay amounts when due under this Agreement): (a) royalties on such sales as if such sales of the licensee or sublicensee were Net Sales of BMS or any of its Affiliates; and (b) milestones payments pursuant toSection 8.4 based on the achievement by such licensee or sublicensee of any milestone event contemplated in such Sections as if such milestone event had been achieved by BMS or any of its Affiliates hereunder. Any sales by BMS’ Affiliates and sublicensees of BMS or such sublicensee’s Affiliates, in each case to Third Parties, shall be aggregated with sales by BMS for the purpose of calculating the aggregate Net Sales inSections 8.4 and8.5.

Each Party shall have the right to have an independent certified public accountant, reasonably acceptable to the audited Party, to have access during normal business hours, and upon reasonable prior written notice, to examine only those records of the audited Party (and its Affiliates and sublicensees) as may be reasonably necessary to determine, with respect to any calendar year ending not more than [*] prior to such Party’s request, the correctness or completeness of any report or payment made under this Agreement. The foregoing right of review may be exercised [*]. Results of any such examination shall be: (a) limited to information relating to the Products; (b) made available to both Parties; and (c) subject toArticle 10.

The results of such audit shall be [*].

8.19Interest.

8.20Non-Monetary Consideration. Neither Party shall sell a Product for any consideration other than cash except on terms specified in the then approved Annual Commercialization Plan. In the event a Party receives any non-monetary consideration in connection with the sale of a Product, such Party’s payment obligations under thisArticle 8 shall be based on the fair market value of such other consideration. In such case, the selling Party shall disclose the terms of such arrangement to the other Parties and the Parties shall endeavor in good faith to agree on such fair market value.

8.21 Cross Border Transactions.

(a)In General. BMS and EXEL recognize that in certain territories, and in particular in free trade regions, customers or other Third Parties may import Product(s) purchased in one country for commercial sale or use in another. If EXEL asks the JEC to determine whether Products purchased outside the U.S. are being imported into the U.S. for such purpose, the JEC shall determine the level that such importation is occurring using data obtained from a source reasonably acceptable to EXEL and BMS. If such importation is [*] (i.e., [*], for [*]) then the JEC shall [*].

(b)Disputes. If the JEC cannot agree whether such importation has [*], then, at the election of either BMS or EXEL, such dispute must be finally resolved through binding arbitration by JAMS in accordance with its Streamlined Arbitration Rules and Procedures in effect at the time the failure arises, except as modified in this Agreement and applying the substantive law specified inSection 14.2. Either BMS or EXEL may initiate arbitration under thisSection 8.21(b)by written notice to such other Party of its intention to arbitrate, and such notice shall specify in

reasonable detail the nature of the dispute. For each arbitration: (i) each of BMS and EXEL shall submit to the arbitrator its proposal for resolving such dispute (i.e., the final form of the equitable mechanism to adjust the compensation of the Parties hereunder to offset the economic effect of cross border transactions described inSection 8.21(a)), such proposal based on the applicable business factors discussed by the JEC; (ii) the arbitrator shall select the proposal that is the most commercially reasonable; and (iii) such proposal shall become such equitable mechanism. Notwithstanding anything to the contrary, the arbitrators will not have the ability to change the terms of either Party’s proposal. The award of the arbitrator shall be final and judgment upon such an award may be entered in any competent court or application may be made to any competent court for judicial acceptance of such an award and order of enforcement. The arbitration proceedings shall be conducted in such location as shall be determined by the arbitrator. BMS and EXEL agree that they shall share equally the cost of the arbitration filing and hearing fees, and the cost of the arbitrator. Each of BMS and EXEL shall bear its own attorneys’ fees and associated costs and expenses.

8.22Payments to or Reports by Affiliates.

Each Party agrees during the term of this Agreement to create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all such intellectual property. If a case is commenced by or against either Party (the “Bankrupt Party”) under Title 11, then, unless and until

this Agreement is rejected as provided in Title 11, the Bankrupt Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 Trustee) shall, at the election of the Bankrupt Party made within sixty (60) days after the commencement of the case (or, if no such election is made, immediately upon the request of the non-Bankrupt Party) either (i) perform all of the obligations provided in this Agreement to be performed by the Bankrupt Party including, where applicable, providing to the non-Bankrupt Party portions of such intellectual property (including embodiments thereof) held by the Bankrupt Party and such successors and assigns or otherwise available to them or (ii) provide to the non-Bankrupt Party all such intellectual property (including all embodiments thereof) held by the Bankrupt Party and such successors and assigns or otherwise available to them.

(b) If a Title 11 case is commenced by or against the Bankrupt Party and this Agreement is rejected as provided in Title 11 and the non-Bankrupt Party elects to retain its rights hereunder as provided in Title 11, then the Bankrupt Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 Trustee) shall provide to the non-Bankrupt Party all such intellectual property (including all embodiments thereof) held by the Bankrupt Party and such successors and assigns or otherwise available to them immediately upon the non-Bankrupt Party’s written request therefor. Whenever the Bankrupt Party or any of its successors or assigns provides to the non-Bankrupt Party any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to thisSection 14.6, the non-Bankrupt Party shall have the right to perform the obligations of the Bankrupt Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the non-Bankrupt Party shall release the Bankrupt Party from any such obligation or liability for failing to perform it.

(c) All rights, powers and remedies of the non-Bankrupt Party provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including Title 11) in the event of the commencement of a Title 11 case by or against the Bankrupt Party. The non-Bankrupt Party, in addition to the rights, power and remedies expressly provided herein, shall be entitled to exercise all other such rights and powers and resort to all other such remedies as may now or hereafter exist at law or in equity (including under Title 11) in such event. The Parties agree that they intend the foregoing non-Bankrupt Party rights to extend to the maximum extent permitted by law and any provisions of applicable contracts with Third Parties, including for purposes of Title 11, (i) the right of access to any intellectual property (including all embodiments thereof) of the Bankrupt Party or any Third Party with whom the Bankrupt Party contracts to perform an obligation of the Bankrupt Party under this Agreement, and, in the case of the Third Party, which is necessary for the development, registration and manufacture of Products and (ii) the right to contract directly with any Third Party described in (i) in this sentence to complete the contracted work. Any intellectual property provided pursuant to the provisions of thisSection 14.6 shall be subject to the licenses set forth elsewhere in this Agreement and the payment obligations of this Agreement, which shall be deemed to be royalties for purposes of Title 11.

14.7 Force Majeure.Each Party shall be excused from the performance of its obligations under this Agreement to the extent that such performance is prevented by force majeure (defined below) and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting force majeure continues and the nonperforming Party takes reasonable efforts to remove the condition. For

purposes of this Agreement, “force majeure” shall include conditions beyond the control of the Parties, including an act of God, acts of terrorism, voluntary or involuntary compliance with any regulation, law or order of any government, war, civil commotion, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe. The payment of invoices due and owing hereunder shall in no event be delayed by the payer because of a force majeure affecting the payer.

Bristol-Myers Squibb and Exelixis Enter Global Collaboration on

Two Novel Cancer Programs

Programs include XL184, a Phase III inhibitor of MET, VEGFR2 and RET,

and XL281, a Phase I Inhibitor of RAF Kinase

PRINCETON, New Jersey, and SOUTH SAN FRANCISCO, California – December XX, 2008 – Bristol-Myers Squibb Company (NYSE: BMY) and Exelixis, Inc. (Nasdaq:EXEL) today announced a global collaboration covering two novel cancer programs: Exelixis’ XL184, a small molecule inhibitor of MET, VEGFR2 and RET, which is currently in Phase III development for medullary thyroid cancer, and its associated development program; and Exelixis’ XL281, a small molecule inhibitor of RAF kinase, which is currently in Phase I development for the treatment of patients with advanced solid tumor malignancies, and its associated development program.

Under the terms of the collaboration, Bristol-Myers Squibb agreed to pay Exelixis an upfront cash payment of $195 million for the development and commercialization rights to both programs and to make additional license payments of $45 million in 2009.

The companies have agreed to co-develop XL184. Exelixis will have the option to co-promote XL184 in the United States. The companies will share worldwide development costs and commercial profits on XL184 in the United States. Exelixis will be eligible to receive sales performance milestones of up to $150 million and royalties on sales outside the United States. The clinical development of XL184 will be directed by a joint committee. It is anticipated that Exelixis will conduct a significant portion of clinical development activities through 2010. Exelixis may opt out of the co-development for XL184 in the United States, in which case Exelixis would instead be eligible to receive development and regulatory milestones of up to $295 million, royalties on XL184 product sales worldwide, and sales performance milestones.

Bristol-Myers Squibb will receive an exclusive worldwide license to develop and commercialize XL281. Bristol-Myers Squibb will be responsible for funding all future development. Exelixis is eligible for development and regulatory milestones of up to $315 million, sales performance milestones of up to $150 million and royalties on worldwide sales of XL281.

“For nearly a decade, the foundation for our close collaborations with Exelixis has been a commitment to discover and develop new medicines to help patients prevail over serious disease,” said Elliott Sigal, M.D., Ph.D., executive vice president, chief scientific officer, and president, Research and Development of Bristol-Myers Squibb. “XL184 and XL281 represent significant new opportunities to inhibit the progression of many different tumor types.

This agreement represents the next pearl in our on-going String of Pearls initiative, designed to accelerate our company’s strategy to transform into a BioPharma leader by blending external scientific innovation with our own internal research and development expertise. Together with Exelixis, we intend to fully explore how these compounds can potentially extend the treatment options of patients with cancer.”

“There have been many attempts to blend the best of big pharma with the best of biotech, and over the years Exelixis and Bristol-Myers Squibb have learned how to do just that. This new collaboration maximizes the capabilities and strengths of each partner and sets the stage for the aggressive development of XL184 and XL281. The collaboration provides the development programs with appropriate resources and positions both compounds to be developed to their full potential in indications with significant commercial potential,” said George Scangos, president and chief executive officer of Exelixis. “Exelixis and Bristol-Myers Squibb are working toward a shared vision of maximizing the potential of these compounds to benefit patients who suffer from numerous types of cancer.”

XL184 provides a novel approach to the treatment of a variety of solid tumors where signaling through MET, VEGFR2 or RET plays an important role in dysregulated tumor growth and progression. XL184 has recently begun a Phase III clinical trials in medullary thyroid cancer, a disease in which RET mutations are found in a large proportion of patients. In addition, clinical trials to exploit the MET and VEGFR2 targeting of XL184 are ongoing in patients with non-small cell lung cancer and glioblastoma. Preclinically, XL184 also exhibits inhibitory activity for MET and VEGFR2 in a variety of breast, colon and brain tumor models.

XL281 is a novel small molecule designed to selectively inhibit RAF kinase, which lies immediately downstream of RAS and is a key component of the RAS/RAF/MEK/ERK kinase signaling pathway. The RAS/RAF/MEK/ERK pathway plays a key role in the transmission of growth-promoting signals downstream of receptor tyrosine kinases. Dysregulation of this pathway plays a pivotal role in the progression of many human tumors, and inhibition of the pathway may be useful in the treatment of cancer. Phase I trials with this molecule are underway in order to select a dose and schedule for Phase II disease-directed trials.

The effectiveness of the agreement is subject to antitrust clearance under the Hart-Scott-Rodino Antitrust Improvements Act and other customary regulatory approvals.
