2.Collaboration

2.1.Overview; Guidelines; and Independence.

(a)Overview. The Parties desire to apply their respective technology and expertise to discover, optimize and advance Collaboration Compounds that are a PI3Kalpha Selective Inhibitor, PI3Kbeta Selective Inhibitor, PI3Kalpha/beta Inhibitor, PI3Kalpha/mTOR Inhibitor, PI3Kbeta/mTOR Inhibitor, or PI3Kalpha/beta/mTOR Inhibitor so that such Collaboration Compounds may be Developed into Products and Commercialized by Sanofi-Aventis. As a general goal, the Parties intend to advance [ * ] Lead Compounds as Development Candidates, and to submit [ * ] INDs on Development Candidates ([ * ] one of which is [ * ] and one of which is [ * ] (both with or without [ * ]), during the Collaborative Research Term. The Parties agree that failure to advance [ * ] such Lead Compounds as Development Candidates, or failure to submit [ * ] such INDs on Development Candidates shall not be treated as a breach of this Agreement. Each Party shall have responsibilities under the Collaboration in accordance with the allocation of duties set forth in the Research Plan, including responsibilities for lead optimization, preclinical development of Collaboration Compounds, and conduct of [ * ] Clinical Trial(s) for such Collaboration Compounds.

(b)Resources. Each Party 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 Pre-Lead Compound, Lead Compound or Development Candidate as if it were a proprietary compound solely of its own organization. In all matters related to the Collaboration, the Parties shall strive to balance as best as 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). Notwithstanding anything to the contrary, during the Collaborative Research Term, Exelixis shall allocate and utilize [ * ] FTEs per year, [ * ] to fulfilling its obligations under the Research Plan, and Sanofi-Aventis shall allocate [ * ] to perform its obligations under the Research Plan.
 
2.2.Research Plan. The Parties have agreed in writing upon an initial plan for the research to be carried out by the Parties during the Collaborative Research Term, which is set forth in the Exhibit 2.2 and incorporated herein by reference (the “Research Plan”). The Research Plan includes each Party’s respective obligations in furtherance of the Collaboration and timelines for completion of key stages. The JRDC shall review the Research Plan at least [ * ] and may propose to the JEC (for its review and approval) revised versions of the Research Plan that do not contradict any terms of this Agreement. Once approved by the JEC, such revised Research Plan shall replace the prior Research Plan. If the terms of the Research Plan contradict, or create inconsistencies or ambiguities with, the terms of this Agreement, then the terms of this Agreement shall govern.

2.3.Conduct of Research.

(a)General. The Parties shall use Diligent Efforts to conduct their respective tasks set forth in the Research Plan and shall conduct the Collaboration in good scientific manner, and in compliance in all material respects with the requirements of applicable laws, rules and regulations and all applicable good laboratory practices.
(b)Pre-Lead Discovery and Nomination. During the Collaborative Research Term, each Party shall use Diligent Efforts to [ * ] and [ * ] of [ * ] to [ * ] and [ * ] as [ * ]. Each Party shall [ * ] the [ * ] and [ * ] identification and characterization (but not any [ * ], [ * ], proprietary [ * ], or [ * ]) with the JRDC at each meeting. Exhibit 2.3(b)(i) identifies (as of the Effective Date) a list of compounds that [ * ] to [ * ] as [ * ] under this Agreement, and Exhibit 2.3(b)(ii) identifies (as of the Effective Date) a list of compounds that [ * ] to [ * ] as [ * ] under this Agreement. Once [ * ] in [ * ] that a given compound meets the Pre-Lead Compound Nomination Criteria identified in the Research Plan, then [ * ] shall submit to the JRDC a data package (excluding [ * ] and [ * ]) for nominating such compound as a Pre-Lead Compound. Alternatively, the JRDC may request [ * ] to assemble and submit (at such [ * ]) a data package (excluding [ * ] and [ * ]) for any PI3Kalpha Selective Inhibitor, PI3Kbeta Selective Inhibitor, PI3Kalpha/beta Inhibitor, PI3Kalpha/mTOR Inhibitor, PI3Kbeta/mTOR Inhibitor, or PI3Kalpha/beta/mTOR Inhibitor that has been disclosed to the JRDC by [ * ]. The JRDC shall review each data package submitted for Pre-Lead Compound nomination and shall determine whether to approve such compound as a Pre-Lead Compound. If the JRDC approves such compound, then such compound shall be deemed to be a Pre-Lead Compound. Upon such approval by the JRDC, the [ * ] and [ * ] for such Pre-Lead Compound shall be [ * ]. If the JRDC does not approve a compound as a Pre-Lead Compound, and the JRDC recommends that such compound should be subject to additional work, then, [ * ] that [ * ] such [ * ] shall use [ * ] to [ * ] such [ * ] and [ * ] such [ * ] to the [ * ] for [ * ]; provided, however, that the JRDC shall have the sole discretion to prioritize such additional work relative to any work being performed [ * ] under this Agreement. If the JRDC does not approve such compound as a Pre-Lead Compound and does not recommend additional work, then such compound shall [ * ] that [ * ] such [ * ], which [ * ] shall have the right to] further research, develop or commercialize such compound [ * ], subject [ * ] to the [ * ] of Section [ * ].

(c)Lead Discovery and Nomination. Once [ * ] determines that [ * ] Pre-Lead Compound meets the Lead Compound Nomination Criteria identified in the Research Plan, then [ * ] shall submit to the JRDC a data package for such Pre-Lead Compound to be approved as a Lead Compound by the JRDC. Alternatively, the JRDC may nominate a Pre-Lead Compound for consideration to be a Lead Compound and request [ * ] to assemble and submit (at such [ * ]) a data package for such Pre-Lead Compound. The JRDC shall review each submitted data package and shall determine whether to approve such Pre-Lead Compound as a Lead Compound, provided, however, that prior to such determination, [ * ] that has [ * ] such [ * ] shall have the right to request and receive, [ * ] appropriate [ * ], [ * ] from the [ * ] of [ * ] than [ * ] of such [ * ] solely to [ * ] the [ * ] and the [ * ] described in the [ * ] and confirm whether such [ * ] of the [ * ] provided meet such [ * ] (for clarity, [ * ] intends for the [ * ] to [ * ] in the [ * ] of [ * ]; accordingly, if any [ * ] from such [ * ], then the [ * ] such [ * ] hereby [ * ] all of its [ * ] and [ * ] to such [ * ] to [ * ]). If the JRDC approves such Pre-Lead Compound, then such Pre-Lead Compound shall be deemed to be a Lead Compound, and shall no longer be deemed to be a Pre-Lead Compound. If the JRDC does not approve a Pre-Lead Compound, and the JRDC recommends that such Pre-Lead Compound should be subject to additional work, then, [ * ] that [ * ] such [ * ] shall use [ * ] to [ * ] such [ * ] and [ * ] such [ * ] to the [ * ] for [ * ]; provided, however, that the JRDC shall have the sole discretion to prioritize such additional work relative to any work

being performed [ * ] under this Agreement. If JRDC does not approve such Pre-Lead Compound and does not recommend additional work, then such Pre-Lead Compound shall cease to be a Pre-Lead Compound, and [ * ] that [ * ] such [ * ] shall have [ * ] to further [ * ] or [ * ] such [ * ], subject [ * ] to the [ * ] of Section [ * ].

(d)Review of Lead Compounds. As part of the criteria for the submission of a Lead Compound for approval as a Development Candidate, [ * ] review the results of all screening assays for [ * ] activity [ * ] or [ * ] of [ * ] in the normal course of [ * ] under the [ * ]. [ * ] may [ * ] such [ * ] for the [ * ] of [ * ] that such [ * ] does [ * ] a [ * ] of [ * ] against any [ * ] for which [ * ] has [ * ] to any [ * ] (“[ * ]”). If [ * ] notifies [ * ] in writing within [ * ] of [ * ] that a [ * ], then [ * ] shall [ * ] such [ * ]; provided, however, that [ * ] may [ * ] on such [ * ] to [ * ] the [ * ] of such [ * ]. For clarity, (a) nothing in this Section 2.3 shall be deemed to [ * ] from [ * ], at any time, with respect to its [ * ] or [ * ] in order to [ * ] such [ * ], and (b) [ * ] may [ * ] and [ * ] with respect to any such [ * ] during such [ * ] prior to [ * ] any such [ * ] from [ * ]. In the event that [ * ] does [ * ] to [ * ] with respect to the [ * ] of a [ * ] within such [ * ], then [ * ] shall be [ * ] on the terms and conditions set forth in this Agreement.

(e)Lead Optimization. During the Collaborative Research Term, the JRDC shall review and prioritize each Lead Compound on a regular basis, allocating the split of responsibilities and resources between the Parties with the goal of advancing a prioritized Lead Compound to Development Candidate by the conduct of the Lead Optimization Responsibilities set forth in the Research Plan, and the factors described below. In general, the responsibilities for [ * ] of a Lead Compound and associated [ * ] (including [ * ] and [ * ]) shall remain with [ * ] that [ * ] such [ * ]; provided, however, that the Parties may agree to allocate some activities (and transfer Lead Compounds) to [ * ] that [ * ] such [ * ] if [ * ] has [ * ] and [ * ] that are [ * ] to the [ * ] (e.g., in the areas of specific [ * ] or [ * ] models, [ * ] assets or access to [ * ])]. During the Collaborative Research Term, each Party shall [ * ] to [ * ] the [ * ] that are [ * ] to [ * ] by [ * ] and to update the JRDC with the progress and results of such conduct. The JRDC shall assess the status of the Lead Compounds, and, if a Lead Compound meets the Development Candidate Nomination Criteria, or if the JRDC otherwise determines that a Lead Compound should be advanced as a Development Candidate for preclinical development, then the JRDC shall nominate such Lead Compound as a Development Candidate to [ * ]. [ * ] shall promptly (and in good faith) review such nomination and determine whether such Lead Compound shall be advanced for preclinical development by becoming a Development Candidate. If [ * ] determines to approve such Lead Compound as a Development Candidate, then [ * ] shall promptly notify the JRDC, and such Lead Compound shall be deemed to be a Development Candidate and shall no longer be deemed to be a Lead Compound. [ * ] shall also determine which Party would be responsible for CMC Activities, preclinical development, IND submission and conduct of the first Phase I Clinical Trial for such Development Candidate. If the JRDC decides not to nominate a Lead Compound as a Development Candidate, or if [ * ] does not approve a Lead Compound as a Development Candidate, and the JRDC [ * ] recommends additional work to be performed on such Lead Compound, then, [ * ] that [ * ] such [ * ] shall use Diligent Efforts to conduct such additional work and re-submit such Lead Compound to the JRDC; provided, however, that the JRDC shall have the sole discretion to prioritize such additional work relative to any work being performed by such Party under this Agreement.

(f)Preclinical Development and IND Submission. After [ * ] determines to advance a Lead Compound as a Development Candidate, [ * ] that was [ * ] the [ * ] for such [ * ] shall use Diligent Efforts during the Collaborative Research Term to conduct the Preclinical Development Activities set forth

in the Research Plan. The JRDC shall assess the status of such Preclinical Development Activities, and, if a Development Candidate meets the IND Submission Criteria, or if the JRDC otherwise determines that an IND should be submitted for a Development Candidate, then the JRDC shall nominate such Development Candidate for IND submission to [ * ]. [ * ] shall promptly (and in good faith) review such nomination and determine whether an IND should be submitted for such Development Candidate. If [ * ] determines that an IND should be submitted, then [ * ] shall promptly notify the JRDC, and the Lead Development Party shall prepare the Initial Development Plan and Annual Development Plan pursuant to Article 5. After the Initial Development Plan and Annual Development Plan are finalized, the Lead Development Party shall use Diligent Efforts to prepare and submit to the applicable Regulatory Authority the IND package for such Development Candidate. If the JRDC determines that an IND should not be submitted for a Development Candidate, or if [ * ] determines not to submit an IND for a Development Candidate, but if either the JRDC or [ * ] recommends that such Development Candidate should be subject to additional work, then, [ * ] that was [ * ] the [ * ] for such [ * ] shall use Diligent Efforts to conduct such additional work and re-submit such Development Candidate to the JRDC [ * ]; provided, however, that the JRDC shall have the sole discretion to prioritize such additional work relative to any work being performed [ * ] under this Agreement. After the INDs for at least [ * ] Development Candidates, have been approved by the appropriate Regulatory Authority [ * ] shall have any obligation to submit (or conduct any work related to the submission of) any additional INDs for any other Development Candidates, and [ * ] shall have any obligation to submit (or conduct any work related to the submission of) any additional Lead Compounds for advancement as Development Candidates.

or [ * ] on the [ * ] labels and material, provided however that Licensee shall not display the Marks in such a manner to suggest that any party (including Licensee) other than Licensor owns the Marks.
 
3.3     In the event of an uncured material breach of the License Agreement by Licensor, or any bankruptcy or insolvency of Licensor, this Agreement (including the license set forth in Section 2.1) shall remain in effect but Licensee shall no longer be obligated pursuant to the preceding Section to continue using any of the Marks

3.4    Licensee shall use the Marks upon or in relation to the Products only in such manner where the distinctiveness, reputation, and validity of the Marks shall not be impaired. Without prejudice to the generality of the foregoing, Licensee shall ensure in particular that the Marks are correctly spelled, and that any text, graphics, or designs adjacent to the Marks do not put the Marks or Licensor in a negative or derogatory light. Licensee shall provide Licensor with proposed Product packaging and corresponding marketing materials prior to publication or shipment of any Product under the Marks.

4.Term and Termination of Agreement.

4.1    The term of this Agreement (the “Term”) shall commence on the Effective Date and shall continue in full force until the expiration or termination of the Collaboration Agreement, unless earlier terminated pursuant to the terms and conditions of this Agreement or pursuant to the mutual written agreement of Licensor and Licensee.

4.2    In the event of a partial termination of the Collaboration Agreement, where the Collaboration Agreement is terminated only in respect to certain Products or certain countries within the Territory, this Agreement shall terminate with respect to those Products and countries in the Territory for which the Collaboration Agreement terminated and this Agreement shall remain in effect with respect to those Products or countries in the Territory which continue to be governed by the Collaboration Agreement.

4.4    Licensor shall also have the right to terminate this Agreement upon written notice to Licensee if, in Licensor’s reasonable discretion, Licensee's use of the Marks tarnishes, blurs, or dilutes the quality associated with the Marks or the associated goodwill and Licensee fails to rectify same within [ * ].

4.5    In the event of termination of this Agreement, the following provisions of this Agreement shall survive: Article 6; and Sections 7.4 and 7.10. In any event, termination of this Agreement shall not relieve the Parties of any liability which accrued hereunder prior to the effective date of such termination nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation.

5.Licensor’s Exclusive Interest in the Marks.

5.1    Licensor hereby warrants to Licensee that Licensor is the owner of the Marks and retains all rights, title and interest in and to the Marks. This Agreement does not grant to Licensee any proprietary right of any of Licensor’s Marks, other than use of the Marks as set forth in this Agreement.

5.2    In the event that management or in-house counsel for Licensee becomes aware of a suspected infringement of a Mark by a Third Party, Licensee shall notify Licensor promptly in writing. Licensee shall provide the same level of disclosure to Licensor’s in-house counsel concerning suspected infringement of a Mark as Licensee would provide to its own in-house counsel with respect to suspected infringement of its own mark. As between the Parties, Licensor shall have the sole right, but shall not be obligated, to bring an action with respect to such suspected infringement at its own expense, in its own name and entirely under its own direction and control.

5.3    In the event that Licensee grants to a Third Party a sublicense of its rights under the Collaboration Agreement to Commercialize one or more Products in one or more countries in the Territory, Licensee shall enter into a sublicense agreement with such Third Party (the “Sublicensee”) that grants the Sublicensee a sublicense of the Licensee’s rights pursuant to Section 2.1 with respect to such Products in such countries in the Territory. Each such sublicense agreement shall be under the same terms and conditions as this Agreement.


[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended.




5.4    Licensee agrees that it will take no action adverse to or inconsistent with Licensor’s ownership of the Marks, including without limitation seeking to register any of the Marks in the Territory, or opposing, disputing, or assisting others in opposing or disputing Licensor’s ownership of the Marks in any way.

5.5    Licensee acknowledges that all use of the Marks and all rights and goodwill attached to or arising out of such use, shall accrue to the benefit of Licensor. Licensee shall at any time, whether during or after the Term, execute any documents that shall reasonably be required by Licensor to confirm Licensor’s ownership of the Marks.

6.Governing Law; Venue.

6.1    This Agreement shall be construed in accordance with, and governed in all respects by, the internal laws of the State of New York, without regard to conflict of law rules.

6.2    Unless otherwise set forth in this Agreement, 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; and further provided, that any dispute, controversy or claim arising out of, relating to or in connection with any Mark shall be submitted to a court of competent jurisdiction in the territory in which such Mark were granted or arose.

7.Miscellaneous.

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party. Notwithstanding the foregoing, and subject to Section 6.3 (d) of the Collaboration Agreement, Licensor may revise Schedule A upon written notice to Licensee.

7.2 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other (such consent to not be unreasonably withheld, delayed or conditioned), except a Party may make such an assignment without the other Party’s consent to an Affiliate or to a Third Party successor to all or substantially all of the business of such Party to which this Agreement relates, whether in a merger, sale of stock, sale of assets or other transaction; provided that any such permitted successor or assignee of rights and/or obligations hereunder is also the permitted successor or assignee of such Party’s rights and obligations pursuant to the Collaboration Agreement and is obligated, by reason of operation of law or pursuant to a written agreement with the other Party, to assume performance of this Agreement or such rights and/or obligations; and provided, further, that if assigned to an Affiliate, the assigning Party shall remain jointly and severally responsible for the performance of this Agreement by such Affiliate. Any permitted assignment shall be binding on the successors of the assigning Party.

EXELIXIS AND SANOFI-AVENTIS SIGN GLOBAL LICENSE AGREEMENT FOR XL147 & XL765 AND LAUNCH BROAD COLLABORATION FOR DISCOVERY OF PI3K INHIBITORS

-Exelixis receives $140 million upfront payment and guaranteed research funding-

Paris, France and South San Francisco, CA - May XX, 2009 -- Sanofi-aventis (EURONEXT: SAN and NYSE: SNY) and Exelixis, Inc. (Nasdaq: EXEL) today announced a global license agreement for XL147 and XL765 and a broad collaboration for the discovery of inhibitors of phosphoinositide-3 kinase (PI3K) for the treatment of cancer. Activation of the PI3K pathway is a frequent event in human tumors, promoting cell proliferation, survival, and resistance to chemotherapy and radiotherapy. Under the license, Sanofi-aventis will have a worldwide exclusive license to XL147 and XL765, which are currently in phase 1 and phase 1b/2 clinical trials, and will have sole responsibility for all subsequent clinical, regulatory, commercial and manufacturing activities. Exelixis will participate in conducting ongoing and potential future clinical trials and manufacturing activities.

Under the discovery collaboration, Exelixis and Sanofi-aventis will combine efforts in establishing several pre-clinical PI3K programs and jointly share responsibility for research and preclinical activities related to isoform-selective inhibitors of PI3K. Sanofi-aventis will have sole responsibility for all subsequent clinical, regulatory, commercial and manufacturing activities of any products arising from the collaboration; however, Exelixis may be responsible for conducting certain clinical trials.

Sanofi-aventis will pay Exelixis a combined upfront cash payment of $140 million under the license and collaboration. Exelixis will also receive guaranteed research funding of $21 million over a three year research term under the collaboration. For both the license and the collaboration, Exelixis will be eligible to receive development, regulatory and commercial milestones of over $1 billion in the aggregate, as well as royalties on sales of any products commercialized under the license and collaboration.

“Sanofi-aventis has a track record of success in commercializing innovative cancer therapies and is deeply committed to advancing the care of cancer patients,” said George A. Scangos, Ph.D., president and chief executive officer of Exelixis. “We believe that their expertise and resources will enable us to move aggressively in advancing the development of XL147 and XL765 and other potential PI3K inhibitors. The data generated to date in the XL147 and XL765 clinical programs suggest that these compounds may have utility in treating diverse cancers. Sanofi-aventis

and Exelixis are committed to realizing the full potential of these compounds and other PI3K inhibitors to provide cancer patients with new treatment options.”

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

Oral Presentations
Clinical data from the phase 1 trials of XL147 and XL765 will be presented at the American Society of Clinical Oncology Annual Meeting, which will be held from May 29 to June 2, 2009 in Orlando, Florida:

“Phase 1 dose-escalation study of XL147, a PI3K inhibitor administered orally to patients with solid tumors” will be presented on Monday, June 1, 2009, starting at 1:30 p.m. local time (Abstract #3500)
“A Phase 1 dose-escalation study of the safety, pharmacokinetics (PK) and pharmacodynamics of XL765, a PI3K/TORC1/TORC2 inhibitor administered orally to patients (pts) with advanced solid tumors” will be presented on Monday, June 1, 2009 starting at 2:00 p.m. local time (Abstract #3502)

XL147 and XL765 target PI3K, which plays an important role in cell proliferation and survival. Activation of the PI3K pathway is a frequent event in human tumors, promoting cell proliferation, survival, and resistance to chemotherapy and radiotherapy. XL765 also inhibits the mammalian target of rapamycin (mTOR), which can be activated via upregulation of PI3K, or via PI3K-independent mechanisms. mTOR is frequently activated in human tumors, and plays a central role in tumor cell proliferation.

About PI3K inhibitors

[ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 24b-2 of the Securities Exchange Act of 1934, as amended.




The phosphoinositide-3-kinase (PI3K) pathway is triggered in normal cells upon exposure to growth factors. It regulates a cascade of proliferation and survival signals. The PI3K pathway is one of the primary deregulated signaling pathways in human cancer. Activation of the PI3K pathway is a frequent event in human tumors, promoting cell proliferation, survival, and resistance to chemotherapy and radiotherapy. Novel therapeutics impacting the PI3K pathway, alone or in combination, are therefore considered to have a high therapeutic potential.

About XL147 and XL765
XL147 is an orally available small molecule inhibitor of phosphoinositide-3-kinase (PI3K). XL765 is a orally available small molecule, dual inhibitor of PI3K and mTOR (mammalian target of rapamycin). mTOR can be activated via upregulation of PI3K, or via PI3K-independent mechanisms. mTOR is frequently activated in human tumors, and plays a central role in tumor cell proliferation.
