If Exelixis does not receive [ * ] Notice from BMS by the end of such [ * ] period, then BMS will, as of the end of such [ * ] period, be deemed to have agreed the Licensed Compound [ *

] (“[ * ]”) and BMS shall be obligated to [ * ] set forth in Section [ * ] no later than [ * ] after the end of such period. If Exelixis receives [ * ] Notice within such [ * ] period and it disagrees with BMS’ assessment of such data, then such dispute shall be resolved by a mutually acceptable independent Third Party expert. Such Third Party expert shall determine, within [ * ] of receipt of the data submitted by Exelixis to BMS pursuant to this Section 3.6 and [ * ], whether such data demonstrate that such Licensed Compound [ * ], and the Parties agree that such Third Party expert’s determination on this issue shall be final, binding, and determinative. The Party against whom the Third Party expert rules shall bear all costs of such Third Party determination. If such Third Party expert determines that data submitted by Exelixis to BMS pursuant to this Section 3.6 demonstrate that such Licensed Compound [ * ], then BMS will, as of the date of such determination, be deemed to have made a [ * ] and BMS shall be obligated to make the milestone payment set forth in Section [ * ] no later than [ * ] after the date of such determination. If such Third Party expert determines that data submitted by Exelixis to BMS pursuant to this Section 3.6 does not demonstrate that such Licensed Compound [ * ], then [ * ] will not have occurred and the parties shall continue to work under the Research Plan in order to [ * ].

3.7 Review of Licensed Compounds. Prior to any determination whether a Licensed Compound meets the Success Criteria for [ * ], Exelixis shall review the results of all [ * ] assays for [ * ] conducted by either Party for a compound that is expected to progress to [ * ]. BMS shall provide Exelixis with the results of all [ * ] assays conducted by or on behalf of relating to [ * ] for each [ * ] Licensed Compound, and sufficient samples of each [ * ] Licensed Compound to have such assays conducted. Exelixis may use such results and samples for the sole purpose of performing assays to verify that such [ * ] Licensed Compound [ * ] of [ * ] any [ * ] for [ * ] to any [ * ] (“[ * ]”). Exelixis shall be responsible for having such assays conducted [ * ] associated with such assays. If Exelixis notifies BMS in writing within [ * ] of receiving a sample of a submitted [ * ] Licensed Compound that such Licensed Compound [ * ], then BMS shall [ * ] or [ * ] such Licensed Compound, and [ * ] to [ * ] such Licensed Compound shall [ * ] ([ * ] to such Licensed Compound); provided, however, that BMS [ * ] such Licensed Compound [ * ] in [ * ] to [ * ] the [ * ] such Licensed Compound.

Each Party shall provide to the other Party such assistance and execute such documents as are reasonably necessary to permit the filing and prosecution of such patent application to be filed on such Sole Invention or Joint Invention, or the issuance, maintenance or extension of any resulting Patent.

7.7 Patent Prosecution and Maintenance; Abandonment.

(a) Joint Patent Committee.

(i) Establishment & Meetings. Promptly after the Effective Date (as defined in the TGR5 License Agreement), the Parties shall establish a committee (the “Joint Patent Committee” or “JPC”). The JPC shall be composed of at least one (1) representative from each Party, at least one of which shall be a patent counsel for such Party. Each Party may change its representative(s) by giving the other Party at least [ * ] prior written notice. The JPC shall meet within [ * ] after the Effective Date (as defined in the TGR5 License Agreement), and once per [ * ] thereafter, or as may be requested by either Party as necessary, by teleconference, videoconference or in person (as determined by the JPC).

(1) Duties. Promptly after the Effective Date (as defined in the TGR5 License Agreement), [ * ] shall oversee (subject to Sections 7.7(a)(ii), (iv) and (v) below) the preparation, filing, prosecution (including any interferences, reissue proceedings and reexaminations) and maintenance of all [ * ] Patents, [ * ] Patents Controlled by [ * ], and [ * ] Patents that in each case are [ * ] (the “[ * ] Patents”), provided that, unless otherwise agreed by the Parties, such responsibilities shall be carried out by: (A) [ * ] by [ * ] the [ * ], unless there exists [ * ] of [ * ] and [ * ]; (B) [ * ] by [ * ], but only in the case where [ * ] described in subsection (A) had [ * ] of [ * ]; or (C) [ * ] in conjunction with [ * ] described in the preceding subsection (A) or (B), as applicable. [ * ], or [ * ], shall provide [ * ] with an update of the filing, prosecution and maintenance status for each of the [ * ] Patents on a periodic basis, and shall use commercially reasonable efforts to consult with and cooperate with [ * ] with respect to the filing, prosecution and maintenance of the [ * ] Patents, including providing [ * ] with drafts of proposed filings to allow [ * ] a reasonable opportunity for review and comment before such filings are due. [ * ], or [ * ], shall provide to [ * ] copies of any papers relating to the filing, prosecution and maintenance of the [ * ] Patents promptly upon their being filed and received.

(2) Decisions. Subsequent to the Effective Date (as defined in the TGR5 License Agreement), in the event of a dispute between the Parties with regard to the preparation, filing, prosecution (including any interferences, reissue proceedings and reexaminations) and maintenance of any [ * ] Patent, the matter shall be promptly referred to the [ * ] of Exelixis and [ * ] for BMS. If these two (2) individuals are unable to resolve the dispute promptly, then the matter shall be promptly elevated to the [ * ] of Exelixis and the [ * ] of BMS. If these two (2) individuals are unable to resolve the dispute promptly, then, subject to Sections 7.7(a)(i)(3), 7.7(a)(i)(4), 7.7(a)(ii), [ * ], and [ * ], [ * ] shall have the final decision, except if such decision: (A) conflicts with the terms of the Agreement; (B) would result in [ * ] described in [ * ] or a [ * ] of the [ * ]; or (C) materially impacts [ * ] prosecution of Patents that [ * ] a [ * ], in which case of subsection 7.7(a)(i)(2)(A) - (C), [ * ] shall have the final decision.

(3) Limitation on Subsection 7.7(a)(i)(2)(B). If [ * ] reasonably believes that filing a new patent application covering a [ * ] (other than the [ * ] of a [ * ]) would result in potential claims [ * ] for [ * ], and if [ * ] disputes with [ * ] that such patent application should be filed, then such dispute shall be discussed as described in the first two (2) sentences of Section 7.7(a)(i)(2), and, if still unresolved, shall be arbitrated pursuant to Section [ * ], and [ * ] shall not have the right to exercise its final-decision making authority pursuant to Subsection 7.7(a)(i)(2)(B) unless the dispute is resolved in [ * ] favor.

(4) Limitation on Subsection 7.7(a)(i)(2)(C). [ * ] hereby covenants that it shall not, without the prior written consent of [ * ] (which shall not be unreasonably delayed or conditioned), during the term of this Agreement, [ * ] the decision-making authority granted to [ * ] pursuant to Subsection 7.7(a)(i)(2)(C) [ * ] that is [ * ] as of the Effective Date or [ * ]. Furthermore, if [ * ] the decision-making authority granted to [ * ] pursuant to Subsection 7.7(a)(i)(2)(C) [ * ] by [ * ], [ * ] or [ * ], and such [ * ] is [ * ] or [ * ] a [ * ] that is [ * ], then [ * ] and [ * ] shall agree, pursuant to Section [ * ], on [ * ] the decision-making authority granted to [ * ] pursuant to Subsection 7.7(a)(i)(2)(C).

(ii) Abandonment. In no event shall [ * ] knowingly permit any of the [ * ] Patents to be abandoned in any country, or elect not to file a new patent application claiming priority to a patent application within the [ * ] Patents either before such patent application’s issuance or within the time period required for the filing of an international (i.e., Patent Cooperation Treaty), regional (including European Patent Office) or national application, without [ * ] written consent (such consent not to be unreasonably withheld, delayed or conditioned) or [ * ] otherwise first being given an opportunity to assume full responsibility (at [ * ] expense) for the continued prosecution and maintenance of such [ * ] Patents or the filing of such new patent application. Accordingly, [ * ], or [ * ], shall provide [ * ] with notice of the allowance and expected issuance date of any patent within the [ * ] Patents, or any of the aforementioned filing deadlines, and [ * ] shall provide [ * ] with prompt notice as to whether [ * ] desires [ * ] to file such new patent application. In the event that [ * ] decides either: (A) not to continue the prosecution or maintenance of a patent application or patent within the [ * ] Patents in any country; or (B) not to file such new patent application requested to be filed by [ * ], [ * ] shall provide [ * ] with notice of this decision at least [ * ] prior to any pending lapse or abandonment thereof, and [ * ] shall thereafter have the right to assume responsibility for the filing, prosecution and maintenance of such patent or patent application. In the event that [ * ] assumes such responsibility for such filing, prosecution and maintenance, [ * ] shall no longer have the responsibility for such filing, prosecution and maintenance of such patent applications and patents, and [ * ] shall cooperate as reasonably requested by [ * ] to facilitate control of such filing, prosecution and maintenance by [ * ]. In the case where [ * ] takes over the filing, prosecution or maintenance of any patent or patent application as set forth above, such patent or patent application shall [ * ] be [ * ] the [ * ], and [ * ] shall [ * ] such patent or patent application.

(iii) Filing, Prosecution and Maintenance of Sole Invention Patents Controlled by BMS. In accordance with this Section 7.7(a)(iii), BMS shall be responsible for the filing, prosecution (including any interferences, reissues and reexaminations) and maintenance of all Sole Invention Patents Controlled by BMS. BMS shall provide to Exelixis copies of any papers relating to the filing, prosecution and maintenance of the Sole Invention Patents Controlled by BMS promptly upon their being filed and received.

(iv) Patent Term Extension. Exelixis and BMS shall each cooperate with each another and shall use commercially reasonable efforts in obtaining patent term extension (including any pediatric exclusivity extensions as may be available) or supplemental protection certificates or their equivalents in any country with respect to patent rights covering the Products. If elections with respect to obtaining such patent term extensions are to be made, [ * ] shall have the right to make the election to seek patent term extension or supplemental protection.

(v) Exelixis Right to Separate Claims. To the extent that any Sole Invention Patent of Exelixis contains claims that cover compounds that are not Licensed Compounds (such compounds, “Separable Compounds”), Exelixis shall have the right to separate any claims that cover such Separable Compounds (and not Licensed Compounds) and to file such claims in a separate application (e.g., a continuation, continuation-in-part, or divisional application). Exelixis shall notify BMS in writing prior to separating such claims, and such separation shall be at Exelixis’ sole expense.

(b) Payment of Prosecution Costs. [ * ] shall bear the out-of-pocket expenses (including reasonable fees for any outside counsel, [ * ]) associated with the filing, prosecution (including any interferences, reissue proceedings and reexaminations) and maintenance of: (X) Patents covering [ * ]; and (Y) the [ * ] Patents other than those [ * ] Patents that are [ * ], provided that if any [ * ] or [ * ] is part of a patent application or patent that is [ * ] but [ * ] that are [ * ], then the Parties shall mutually agree upon an appropriate allocation of the expenses so that [ * ] does not bear any portion of the out-of-pocket expenses attributable to [ * ].

(c) Payment of Expenses for Joint Invention Patents. Exelixis and BMS shall mutually agree on the percentage of expenses that each Party shall bear with respect to Joint Invention Patents for which the cost of filing, prosecuting or maintaining such Joint Invention is not the responsibility of a Party under Section 7.7(b) hereof (which, in the absence of any other agreement between the Parties, shall be divided evenly).

(d) Non-payment of Expenses.

(i) If a Party elects not to pay its share of any expenses with respect to [ * ] Patent in a given country under any of Section [ * ], such Party shall inform the other Party in writing not less than [ * ] before any relevant deadline (or, in the event of a shorter period in which to respond to a patent office, as soon as reasonably practicable), and, if the other Party assumes the expenses associated with the [ * ] Patent, then the assuming Party shall thereby become the sole owner of such [ * ] Patent in such country and the other Party shall assign to the assuming Party its rights, title and interests in such [ * ] Patent in such country.

(ii) If a Party is the assignee or owner of a Patent (other than [ * ]) that is licensed to the other Party under any of Sections 7.1 or 7.2, and such owning Party elects not to pay its share of expenses pursuant to Section [ * ] in a given country, such owning Party shall inform the other Party in writing not less than [ * ] before any relevant deadline (or, in the event of a shorter period in which to respond to a patent office, as soon as reasonably practicable). If the other Party assumes the expenses associated with the Patent in such country, then the assuming Party shall thereby [ * ] such Patent and the owning Party shall [ * ] such Patent in such country.

(iii) If a Party is the licensee of a Patent (other than [ * ]) under any of Sections 7.1 or 7.2, and such Party elects not to pay its share of expenses pursuant to Section [ * ] in a given country, such Party shall inform the other Party in writing not less than [ * ] before any relevant deadline (or, in the event of a shorter period in which to respond to a patent office, as soon as reasonably practicable) (such Patent(s) in such countries, as identified in such notice, being a “Cost-Terminated Patent Right”), and shall no longer have any rights under such Sections 7.1 or 7.2, as applicable, with respect to the relevant Patent in such country, provided that all remaining

rights and licenses under all other Patent(s) within such licensed Patents would remain in effect. It is also understood that such licensee shall be offered the opportunity to assume its share of the responsibility for the costs of filing, prosecution and maintenance of any Patent(s) claiming priority directly or indirectly from any such Cost-Terminated Patent Right, and that where such expenses are assumed by such licensee, it shall be afforded all the rights and licenses as provided under this Agreement for the licensed Patents (other than the Cost-Terminated Patent Right) with respect to such Patent(s) claiming priority directly or indirectly from any such Cost-Terminated Patent Right.

(e) Each Party shall provide to the other Party, on [ * ] basis, a patent report that includes the serial number, docket number and status of each Patent for which such Party has the right to direct the filing, prosecution and maintenance and which [ * ] (in the case of [ * ] such [ * ] that are [ * ]) or [ * ]. The Parties through their patent counsel shall discuss as appropriate (but not more than [ * ]) ways in which to allocate such out-of-pocket expenses in an appropriate, cost-effective manner consistent with the purposes of this Agreement [ * ].

All royalties due under Section 8.3 shall be paid quarterly, on a country-by-country basis, within [ * ] of the end of the relevant quarter for which royalties are due. BMS shall provide to Exelixis within [ * ] after the end of each quarter a report that summarizes the Net Sales of a Product during such quarter, provided that to the extent additional information is reasonably required by Exelixis to comply with its obligations to any of its licensors, the Parties shall work together in good faith to timely compile and produce such additional information. Such reports shall also include detailed information regarding the calculation of royalties due pursuant to Section 8.3, including allowable deductions in the calculation of Net Sales of each Product on which royalties are paid, and, to the extent Section 8.5 is applicable, the calculation of [ * ] and [ * ] of [ * ].

8.8 Term of Royalties. Exelixis’ right to receive royalties under Section 8.3 shall expire on a country-by-country and Product-by-Product basis upon the later of: (a) [ * ]; or (b) [ * ] (the “Royalty Term”).

8.12 Sublicenses. In the event BMS grants any permitted licenses or sublicenses to Third Parties to sell Products that are subject to royalty payments under Section 8.3, 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 Exelixis (or cause the licensee or sublicensee to pay to Exelixis, 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 to Section 8.2 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 in Sections 8.2(b) and 8.3.

8.13 Foreign Exchange.

All such books, records and accounts shall be retained by BMS until the later of (a) [ * ] after the end of the period to which such books, records and accounts pertain and (b) the [ * ] (or any extensions thereof), or for such longer period as may be required by applicable law. BMS shall require its sublicensees to provide to it a report detailing the foregoing expenses and calculations incurred or made by such sublicensee, which report shall be made available to Exelixis in connection with any audit conducted by Exelixis pursuant to Section 8.15.

8.15 Audits. Exelixis shall have the right to have an independent certified public accountant, reasonably acceptable to BMS, to have access during normal business hours, and upon reasonable prior written notice, to examine only those records of BMS (and its Affiliates and sublicensees) as may be reasonably necessary to determine, with respect to any calendar year ending not more than [ * ] prior to Exelixis’ 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 to Article 10. Exelixis shall bear the full cost of the performance of any such audit, unless such audit discloses a variance to the detriment of Exelixis of more than [ * ] from the amount of the original report, royalty or payment calculation, in which case BMS shall bear the full cost of the performance of such audit. The results of such audit shall be [ * ].

8.16 Interest. Any payments or portions thereof due hereunder that are not paid on the date such payments are due under this Agreement shall bear interest at a rate equal to the lesser of: (a) [ * ] Rate as published by Citibank, N.A., New York, New York, or any successor thereto, at 12:01 a.m. on the first day of each quarter in which such payments are overdue; or (b) the maximum rate permitted by law, in each case calculated on the number of days such payment is delinquent, compounded monthly.

8.17 Non-Monetary Consideration. In the event that BMS or its Affiliate or sublicensee receives any non-monetary consideration in connection with the sale of a Product, BMS’ payment obligations under this Article 8 shall be based on the fair market value of such other consideration. In such case, BMS shall disclose the terms of such arrangement to Exelixis and the Parties shall endeavor in good faith to agree on such fair market value.

8.18 Payments to or Reports by Affiliates. Any payment required under any provision of this Agreement to be made to either Party or any report required to be made by any Party shall be made to or by an Affiliate of that Party if designated in writing by that Party as the appropriate recipient or reporting entity.

CONFIDENTIALITY

10.1 Nondisclosure of Confidential Information. All Information or Materials disclosed by one Party to the other Party pursuant to this Agreement, and, subject to Section 10.6, Information that is generated pursuant to this Agreement with respect to Licensed Compounds or Products (for so long as such Licensed Compound or Product is not removed from the Agreement as a result of a Product specific termination pursuant to Section 11.3), shall be “Confidential Information” for all purposes hereunder. The Parties agree that, during term of this Agreement and for a period of [ * ] thereafter, a Party receiving Confidential Information of the other Party shall: (a) use Diligent Efforts to maintain in confidence such Confidential Information (but not less than those efforts as such Party uses to maintain in confidence its own proprietary industrial information of similar kind and value) and not to disclose such Confidential Information to any Third Party without prior written consent of the other Party (such consent not to be unreasonably withheld, delayed or conditioned), except for disclosures made in confidence to any Third Party under terms consistent with this Agreement and made in furtherance of this Agreement or of rights granted to a Party hereunder; and (b) not use such other Party’s Confidential Information for any purpose except those permitted by this Agreement (it being understood that this Section 10.1 shall not create or imply any rights or licenses not expressly granted under Article 4, 7 or 11 hereof).

10.2 Exceptions. The obligations in Section 10.1 shall not apply with respect to any portion of the Confidential Information that the receiving Party can show by competent written proof:

(a) Is publicly disclosed by the disclosing Party, either before or after it is disclosed to the receiving Party hereunder; or

(d) Is published by a Third Party or otherwise becomes publicly available or enters the public domain, either before or after it is disclosed to the receiving Party, and is not

directly or indirectly supplied by the receiving Party in violation of this Agreement; or

(e) Has been independently developed by employees or contractors of the receiving Party or any of its Affiliates without the aid, application or use of the disclosing Party’s Confidential Information.

10.3 Authorized Disclosure. A Party may disclose the Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary in the following instances; provided that notice of any such disclosure shall be provided as soon as practicable to the other Party:

(a) Filing or prosecuting Patents relating to Sole Inventions, Joint Inventions or Products, in each case pursuant to activities under this Agreement;

(b) Regulatory filings;

(c) Prosecuting or defending litigation;

(d) Complying with applicable governmental laws and regulations; and

(e) Disclosure, in connection with the performance of this Agreement, or exercise of its rights hereunder, to Affiliates, potential collaborators, partners, and actual and potential licensees (including potential co-marketing and co-promotion contractors, research contractors and manufacturing contractors), research collaborators, potential investment bankers, investors, lenders, and investors, employees, consultants, or agents, each of whom prior to disclosure must be bound by similar obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 10.

The Parties acknowledge that the terms of this Agreement shall be treated as Confidential Information of both Parties. Such terms may be disclosed by a Party to individuals or entities covered by Section 10.3(e) above, each of whom prior to disclosure must be bound by similar obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 10. In addition, a copy of this Agreement may be filed by either Party with the Securities and Exchange Commission in connection with any public offering of such Party’s securities, in connection with such Party’s on-going periodic reporting requirements under the federal securities laws, or as otherwise necessary under applicable law or regulations. In connection with any such filing, such Party shall endeavor to obtain confidential treatment of economic, competitively sensitive, and trade secret information.

10.4 Prior Confidentiality Agreement. All Information exchanged between the Parties under the Confidential Disclosure Agreement between Exelixis and BMS executed as of [ * ], and amended as of [ * ] and [ * ] (such confidential disclosure agreement, as amended, the “Prior CDA”) that relates to ROR, ROR Antagonists, [ * ] and [ * ] ROR Antagonists, Licensed Compounds or Products shall be deemed Confidential Information and shall, commencing upon the Effective Date, be subject to the terms of this Article 10 rather than the Prior CDA. The Prior CDA shall otherwise remain in full force and effect, including with respect to each Party’s rights with respect to breaches thereof, if any, that occurred prior to the Effective Date with respect to

Information described in the first sentence of this Section 10.4.

10.5 Publicity. The Parties agree that the public announcement of the execution of this Agreement shall be substantially in the form of the press release attached as Exhibit 10.5. Any other publication, news release or other public announcement relating to this Agreement or to the performance hereunder, shall first be reviewed and approved by both Parties; provided, however, that any disclosure which is required by law, including disclosures required by the U.S. Securities and Exchange Commission or made pursuant to the requirements of the national securities exchange or other stock market on which such Party’s securities are traded, as advised by the disclosing Party’s counsel may be made without the prior consent of the other Party, although the other Party shall be given prompt notice of any such legally required disclosure and to the extent practicable shall provide the other Party an opportunity to comment on the proposed disclosure.

10.6 Publications. Subject to Section 10.3, each Party agrees to provide the other Party the opportunity to review any proposed disclosure which contains Confidential Information of the other Party and would or may constitute an oral, written or electronic public disclosure if made (including the full content of proposed abstracts, manuscripts or presentations) which relate to any Inventions, at least [ * ] prior to its intended submission for publication and agrees, upon request, not to submit any such abstract or manuscript for publication until the other Party is given a reasonable period of time to secure patent protection for any material in such publication which it believes to be patentable; provided, however, that BMS may publish results of clinical studies relating to Licensed Compounds without the prior review or approval of Exelixis. Both Parties understand that a reasonable commercial strategy may require delay of publication of information or filing of patent applications. The Parties agree to review and consider delay of publication and filing of patent applications under certain circumstances. The Alliance Managers (or the Parties), as appropriate, shall review such requests and recommend subsequent action. Subject to Section 10.3, neither Party shall have the right to publish or present Confidential Information of the other Party which is subject to Section 10.1. Nothing contained in this Section 10.6 shall prohibit the inclusion of Confidential Information of the non-filing Party necessary for a patent application, provided the non-filing Party is given a reasonable opportunity to review the extent and necessity for its Confidential Information to be included prior to submission of such patent application related to the Agreement. Any disputes between the Parties regarding delaying a publication or presentation to permit the filing of a patent application shall be referred to the Alliance Managers (or the Parties), as appropriate.

13.3 Conditions to Indemnification. As used herein, “Indemnitee” shall mean a party entitled to indemnification under the terms of Sections 13.1 or 13.2. A condition precedent to each Indemnitee’s right to seek indemnification under such Sections 13.1 or 13.2 is that such Indemnitee shall:

(a) inform the indemnifying Party under such applicable Section of a Loss as soon as reasonably practicable after it receives notice of the Loss;

(b) if the indemnifying Party acknowledges that such Loss falls within the scope of its indemnification obligations hereunder, permit the indemnifying Party to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Loss (including the right to settle the claim solely for monetary consideration); provided, that the indemnifying Party shall seek the prior written consent (such consent not to be unreasonably withheld, delayed or conditioned) of any such Indemnitee as to any settlement which would materially diminish or materially adversely affect the scope, exclusivity or duration of any Patents licensed under this Agreement, would require any payment by such Indemnitee, would require an admission of legal wrongdoing in any way on the part of an Indemnitee, or would effect an amendment of this Agreement; and

(c) fully cooperate (including providing access to and copies of pertinent records and making available for testimony relevant individuals subject to its control) as reasonably requested by, and at the expense of, the indemnifying Party in the defense of the Loss.

Provided that an Indemnitee has complied with all of the conditions described in subsections 13.3(a) – (c), as applicable, the indemnifying Party shall provide attorneys reasonably acceptable to the Indemnitee to defend against any such Loss. Subject to the foregoing, an Indemnitee may participate in any proceedings involving such Loss using attorneys of the Indemnitee’s choice and at the Indemnitee’s expense. In no event may an Indemnitee settle or compromise any Loss for which the Indemnitee intends to seek indemnification from the indemnifying Party hereunder without the prior written consent of the indemnifying Party (such consent not to be unreasonably withheld, delayed or conditioned), or the indemnification provided under such Section 13.1 or 13.2 as to such Loss shall be null and void.

MISCELLANEOUS

14.1 Dispute Resolution. Unless otherwise set forth in this Agreement and excluding in particular any dispute described in Section 14.3(a), Section 14.3(b), Section [ * ] (which will be handled exclusively in accordance with Section [ * ]), Section [ * ] (which will be handled exclusively in accordance with Section [ * ])and any dispute handled pursuant to Sections [ * ], in the event of any dispute, controversy or claim arising out of, relating to or in connection with any provision of the Agreement, the Parties shall try to settle their differences amicably between themselves first, by referring the disputed matter to the Party’s respective Executive Officers. Either Party may initiate such informal dispute resolution by sending written notice of the dispute to the other Party, and, within [ * ] after such notice, such Executive Officers shall meet for attempted resolution by good faith negotiations. If such Executive Officers are unable to resolve such dispute within [ * ] of their first meeting for such negotiations, either Party may seek to have such dispute resolved in any U.S. federal or state court of competent jurisdiction and appropriate venue, provided, that if such suit includes a Third Party claimant or defendant, and jurisdiction and venue with respect to such Third Party appropriately resides outside the U.S., then in any other jurisdiction or venue permitted by applicable law.

14.2 Governing Law. Resolution of all disputes, controversies or claims arising out of, relating to or in connection with the Agreement or the performance, enforcement, breach or termination of the Agreement and any remedies relating thereto, shall be governed by and construed under the substantive laws of the State of Delaware, without regard to conflicts of law rules.

14.3 Patents and Trademarks; Equitable Relief.

(a) General Patent and Trademark Disputes. Except as set forth in Sections 14.3(c) and (d), any dispute, controversy or claim arising out of, relating to or in connection with: (i) the scope, validity, enforceability or infringement of any Patent rights covering the research, development, manufacture, use or sale of any Product; or (ii) any trademark rights related to any Product, shall in each case be submitted to a court of competent jurisdiction in the territory in which such Patent or trademark rights were granted or arose.

(b) Equitable Relief. Any dispute, controversy or claim arising out of, relating to or in connection with the need to seek preliminary or injunctive measures or other equitable relief (e.g., in the event of a potential or actual breach of the confidentiality and non-use provisions in Article 10) need not be resolved through the procedure described in Section 14.1 but may be immediately brought in a court of competent jurisdiction.

(c) Disputes Related to Subsection [ * ]. Any dispute that concerns whether [ * ] a [ * ] (other than [ * ] of a [ * ]) would [ * ] and that is not resolved by discussion pursuant to Section [ * ] shall be finally resolved through binding arbitration by JAMS (formerly, the Judicial Arbitration and Mediation Service) (“JAMS”), in accordance with its Streamlined Arbitration Rules and Procedures in effect at the time the dispute arises, and applying the substantive law specified in Section 14.2. Either Party may initiate arbitration under this Section 14.3(c) by written notice to the other Party of its intention to arbitrate, and such notice shall specify in reasonable detail the nature of the dispute. Promptly following receipt of such notice, the Parties 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 Parties, shall have significant experience and expertise in [ * ] pharmaceutical products, and shall have some experience in mediating or arbitrating issues relating to such [ * ]. If

the Parties cannot agree on such arbitrator within [ * ] of request by a Party for arbitration, then such arbitrator shall be appointed by JAMS, which arbitrator must meet the foregoing criteria. For each arbitration: (i) each Party shall submit to the arbitrator its memorandum (the “Support Memorandum”) in support of its position in the dispute; and (ii) the arbitrator shall determine which Party’s position is correct. If the arbitrator’s determination is in [ * ] favor, then [ * ] would not [ * ] under Section [ * ] for such [ * ]; however, if the arbitrator’s determination is in [ * ] favor, then [ * ] would [ * ] under Section [ * ] for such [ * ]. The decision of the arbitrator shall be final and judgment upon such decision may be entered in any competent court or application may be made to any competent court for judicial acceptance of such decision and order of enforcement. The arbitration proceedings shall be conducted at such location as shall be determined by the arbitrator. The Parties agree that they shall share equally the cost of the arbitration filing and hearing fees, and the cost of the arbitrator. Each Party shall bear its own attorneys’ fees and associated costs and expenses.

(d) Disputes Related to Subsection [ * ]. If [ * ] and the [ * ] that [ * ] pursuant to Subsection [ * ] do not agree upon [ * ] that reasonably [ * ] within [ * ] after the [ * ] such [ * ], then either party may, by written notification to the other party, submit the matter to binding “baseball” arbitration to determine the terms of such [ * ], as follows. Promptly following receipt of such notice, the parties 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 parties, shall have significant experience and expertise in [ * ] pharmaceutical products and in [ * ] as part of collaboration agreements, and shall have some experience in mediating or arbitrating issues relating to such [ * ]. If the parties cannot agree on such arbitrator within [ * ] of request by a party for arbitration, then such arbitrator shall be appointed by JAMS, which arbitrator must meet the foregoing criteria. Within [ * ] after an arbitrator is selected (or appointed, as the case may be), each party will deliver to both the arbitrator and the other party a detailed written proposal setting forth its proposed terms for the [ * ] containing the reasonable [ * ] (the “Proposed Terms” of the party) and a Support Memorandum, not exceeding [ * ] in length. The parties will also provide the arbitrator a copy of this Agreement, as may be amended at such time. Within [ * ] after receipt of the other party’s Proposed Terms and Support Memorandum, each party may submit to the arbitrator (with a copy to the other party) a response to the other party’s Support Memorandum, such response not exceeding [ * ] in length. Neither party 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 this Section 14.3(d); provided that, the arbitrator may convene a hearing if the arbitrator so chooses to ask questions of the parties and hear oral argument and discussion regarding each party’s Proposed Terms. Within [ * ] after the arbitrator’s appointment, the arbitrator will select one of the two (2) Proposed Terms (without modification) provided by the parties 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 the parties shall promptly [ * ] 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 [ * ] one of the two (2) sets of Proposed Terms, and may not combine elements of both Proposed Terms or take any other action. Except as expressly stated in this Section 14.3(d), such arbitration shall be conducted in accordance with JAMS’ Streamlined Arbitration Rules and Procedures then in effect.

14.4 Entire Agreement; Amendments. This Agreement, the LXR Collaboration Agreement, the license agreement (for the discovery, development and commercialization of compounds that agonize the target known as TGR5) that is between Exelixis and BMS and that is dated as of the Effective Date (the “TGR5 License Agreement”), and the letter agreement that is dated as of the Effective Date and that describes Exelixis’ creation of a licensing Affiliate (the “Letter Agreement”), set forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto and supersedes and terminates all prior agreements and understandings between the Parties. There are no covenants, promises, agreements, warranties, representations, conditions or understandings, either oral or written, between the Parties other than as are set forth in this Agreement, the LXR Collaboration Agreement, the TGR5 License Agreement and the Letter Agreement.

14.5 Export Control. This Agreement is made subject to any restrictions concerning the export of products or technical information from the U.S. or other countries which may be imposed upon or related to Exelixis or BMS from time to time. Each Party agrees that it shall not export, directly or indirectly, any technical information acquired from the other Party under this Agreement or any products using such technical information to a location or in a manner that at the time of export requires an export license or other governmental approval, without first obtaining the written consent to do so from the appropriate agency or other governmental entity.

14.6 Bankruptcy.

(a) All rights and licenses granted under or pursuant to this Agreement, including amendments hereto, by each Party to the other Party are, for all purposes of Section 365(n) of Title 11 of the U.S. Code (“Title 11”), licenses of rights to intellectual property as defined in Title 11. 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 this Section 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 this Section 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.

14.8 Notices. Any notices given under this Agreement shall be in writing, addressed to the Parties at the following addresses, and delivered by person, by facsimile (with receipt confirmation), or by FedEx or other reputable courier service. Any such notice shall be deemed to have been given: (a) as of the day of personal delivery; (b) one (1) day after the date sent by facsimile service; or (c) on the day of successful delivery to the other Party confirmed by the courier service.

EXELIXIS LICENSES PROGRAMS TO BRISTOL-MYERS SQUIBB COMPANY

-Exelixis to receive initial payment of $60 million-

SOUTH SAN FRANCISCO, Calif., October XX, 2010 — Exelixis, Inc. (NASDAQ: EXEL) announced today that it has entered into two new collaboration agreements with Bristol-Myers Squibb Company (NYSE:BMY). Under the first agreement, Exelixis will grant to Bristol-Myers Squibb an exclusive license to its small-molecule TGR5 agonist program including backups. Under the second agreement, the companies will collaborate to discover, optimize, and characterize small-molecule ROR antagonists. The companies have also made minor amendments to their XL281 and liver X receptor (LXR) agreements. Finally, under the companies’ cancer collaboration agreement Exelixis has opted to exercise its right to opt out of further co-development of XL139 and will receive an accelerated milestone payment.

Under the terms of the new agreements, Bristol-Myers Squibb will make a combined initial payment of $60 million to Exelixis. Exelixis will be eligible for potential development and approval milestone payments of up to $250 million on TGR5 and $255 million on the ROR antagonists. Exelixis will also be eligible for combined sales performance milestones, and royalties on net sales of products from each of the TGR5 and ROR programs. Bristol-Myers Squibb will receive an exclusive worldwide license to develop and commercialize small molecule TGR5 agonists and ROR antagonists. Under the TGR5 agreement, Bristol-Myers Squibb will have sole responsibility for research, development, manufacturing, and commercialization. Under the ROR agreement, Bristol-Myers Squibb and Exelixis will collaborate on ROR antagonist programs up to a pre-clinical transition point and then Bristol-Myers Squibb will have sole responsibility for the further research, development, manufacture, and commercialization.

Exelixis is granting rights to the ROR program in exchange for Bristol-Myers Squibb waiving rights to receive a third Investigational New Drug (IND) candidate as agreed to under a collaboration signed in 2006 between the two companies in the area of oncology.

After Exelixis opts-out of further co-development of XL139, Bristol-Myers Squibb will receive an exclusive worldwide license to develop and commercialize, and will have sole responsibility for the further development, manufacture, and commercialization of the compound.

“We continue our strong relationship with Bristol-Myers Squibb and are excited for these collaborations to maximize the potential of these novel programs and bring benefits to patients with serious diseases,” said Michael M. Morrissey, Ph.D., president and chief executive officer of Exelixis. “These transactions leverage our discovery expertise with the development expertise of Bristol-Myers Squibb in inflammation and metabolic diseases, and provide important additional resources for us to continue our focus on our clinical stage development pipeline.”

TGR5 is a G-protein coupled bile acid receptor (GPCR) which is highly expressed in the gall bladder and intestine. Through TGR5, bile acids promote the secretion of glucogen-like peptide-1 (GLP-1), a hormone that affects multiple metabolic parameters including increased insulin secretion from the pancreas and lowering of blood glucose. Stimulating GLP-1 secretion by activation of TGR5 has the potential to be complementary to the use of dipeptidyl peptidase-4 (DPP-IV) inhibitors for the treatment of diabetes.

ROR is a member of the nuclear hormone receptor family that is expressed in multiple cell types including T-cells. ROR plays a prominent role in the development and activity of the TH17 subset of T-cells, which secrete IL-17 and are associated with a variety of inflammatory disorders. Small molecule antagonists of ROR inhibit production of these pro-inflammatory cytokines and have broad potential as novel anti-inflammatory compounds.

The TGR5 license agreement and the amendment to the 2007 cancer collaboration agreement are subject to antitrust clearance under the Hart-Scott-Rodino Antitrust Improvements Act and other customary regulatory approvals.
