LICENSE AND RESEARCH AGREEMENT

(Amended and Restated)

This License And Research Agreement (the “Agreement”) is made and entered into as of September 2, 1999, (the “Effective Date”), as first amended and restated on March 26, 2001 and again amended and restated on July 1, 2001 (the “Restatement Date”), by and between Rigel Pharmaceuticals, Inc., a corporation organized under the laws of Delaware and having a principal place of business at 240 East Grand Avenue, South San Francisco, CA 94080 (“Rigel”) and Cell Genesys, Inc., a corporation organized under the laws of Delaware and having a principal place of business at 342 Lakeside Drive, Foster City, CA 94404 (“CG”). Rigel and CG may be referred to collectively as the “Parties,” or individually as a “Party.”

Recitals

Whereas, CG controls rights to certain patents relating to [ * ] cell lines [ * ] and [ * ] cell lines (Rockefeller), and related technology;

Whereas, Rigel has a license to the [ * ] cell lines, associated vectors and vector libraries under intellectual property rights owned by Stanford University;

Whereas, CG and Rigel desire to enter into an agreement granting each other licenses under such patents and other intellectual property rights as provided herein;

Whereas, Rigel is in the business of, among other things, providing services for identifying molecules which bind together in intracellular signaling pathways, and CG desires that Rigel perform such services for CG to identify peptides, proteins and/or Genetic Material (as defined below) that modulate angiogenesis in endothelial tissues;

Whereas, Rigel wishes to perform additional research in the Field of Research (as defined below) for CG and Novartis Pharma AG (“Novartis”) funded by Novartis, as a combined program of research expanding upon the research that Rigel has already as of the Restatement Date conducted, such that Rigel will be able to continue its research effort in the Field of Research and the overall resources that Rigel will be able to devote to identifying peptides, proteins and/or Screened Genetic Material (as defined below) that modulate angiogenesis in endothelial tissues will be increased; and

Whereas, The Parties wish to confirm CG rights to all Therapeutic Candidates (as defined below) that Rigel identifies in the combined research program, but Rigel needs, in order to make such arrangement acceptable to Novartis, the unambiguous right pursuant to this Agreement to grant Novartis certain rights with respect to all Targets (as defined below) for Novartis’s use as targets in Novartis’s drug discovery efforts, and CG is willing to waive certain of its rights and to amend and restate this Agreement to assure Rigel such unambiguous right;

Now THEREFORE, in consideration of the foregoing premises and the covenants and promises contained in this Agreement, the Parties agree as follows:

LICENSES

2.1 CG License Grants.

(a) Subject to the terms of the CG License, CG hereby grants to Rigel a royalty-free, non-exclusive, worldwide license, with the right to sublicense to Rigel Collaboration Partners, under and to CG’s right, title and interest in the CG Patents and CG Know-How, and under and to CG’s right, title and interest in any Program Technology owned solely by CG, all for purposes solely within the Rigel Field; and hereby waives any claims against Rigel for the practice and use of the CG Patents and CG Know-How within the Rigel Field prior to the Effective Date. Any sublicense granted hereunder to Rigel Collaboration Partners shall be limited to the purposes of such collaboration (as such purposes are described in Section 1.22 above).

(b) Subject to Section 2.4 below, CG hereby grants to Rigel:

(i) a royalty-free, exclusive, worldwide license, with the right to grant and authorize sublicenses, under CG’s right, title and interest in the Program Technology that is owned jointly by the Parties under Section 4.1(d) below, and Targets that are similarly owned jointly with Rigel, all to make and use the Targets for purposes outside the CG Program Field; and

(ii) a royalty-free, exclusive, worldwide license, under CG’s right, title and interest in the Program Technology that is owned jointly by the Parties under Section 4.1(d) below, and Targets that are similarly owned jointly with Rigel, all to make and use the Targets as targets for the purposes of elucidating protein pathways and identifying, researching, developing and/or commercializing proteins, peptides, antibodies, Screened Genetic Material, other biological agents and synthetic organic molecules that are not themselves Therapeutic Candidates but that modulate angiogenesis in endothelial tissues solely in connection with the Novartis Angiogenesis Collaboration. Such license does not extend to the making or use of Targets for the purposes of development and/or commercialization of Therapeutic Candidates in the CG Program Field.

It is understood and agreed that the licenses granted above in this Section 2.1(b) shall specifically exclude the right to make or use any Target or Therapeutic Candidate as a therapeutic agent or for purposes relating to delivery of a Target or Therapeutic Candidate via Gene Therapy. The license set forth in Section 2.1(b)(ii) above shall include the right to grant a sublicense solely to Novartis under the Novartis Angiogenesis Collaboration and to authorize further sublicenses by Novartis solely in connection with Novartis’s research and development programs; provided that any sublicense from Rigel to Novartis under the rights licensed to Rigel pursuant to Section 2.1(b)(ii) (and any further sublicense by Novartis under such rights) shall not exceed the scope of the license granted Rigel pursuant to Section 2.1(b)(ii). Rigel shall retain the right to grant to CG the licenses set forth in Section 2.2 of this Agreement. If Rigel fails to retain such right under the Novartis Angiogenesis Collaboration, the license granted Rigel under Section 2.1(b)(ii) shall terminate.

(c) CG has entered into a license agreement with the [ * ] concerning the [ * ] Patents which includes the right to sublicense (the “[ * ] Agreement”); as of the Effective Date, however, the terms under which CG may grant sublicenses under the [ * ] Agreement make impractical a sublicense to Rigel under the [ * ] Patents for purposes of the Rigel Field. In the event that CG successfully renegotiates the terms of the [ * ] Agreement such that such sublicense would be practical, CG agrees to discuss in good faith the grant of a sublicense to Rigel under the [ * ] Patents. The Parties understand and agree, however, that CG is not and shall not be obligated to enter into any agreement with Rigel concerning the [ * ] Patents, that failure to reach such an agreement for any reason shall not be deemed a breach of this Agreement and that this Section 2.1(c) shall not be deemed to preclude CG from entering into an agreement with a third party of any type or at any time concerning the [ * ] Patents.

2.2 Rigel License Grants.

(a) Subject to the terms and prior to the termination or expiration of the Rigel License, the Parties agree that Rigel shall grant to CG, at CG’s sole option and upon CG’s request, a royalty-free, non-exclusive, worldwide license, without the right to sublicense, under Rigel’s right, title and interest in the Rigel Know-How and Rigel Biological Materials, to make, have made, use, sell, offer for sale and import products in the CG [ * ] Field. It is understood that in no event will CG have any obligation to obtain such license from Rigel. Rigel will give CG thirty (30) days prior written notice of the termination of the Rigel License by Rigel.

(b) Rigel hereby grants to CG:

(i) subject to Section 2.1(b) above, (y) a royalty-free, exclusive, worldwide license, with the right to grant and authorize sublicenses, under Rigel’s right, title and interest in the Program Technology (including without limitation the Therapeutic Candidates) owned solely by Rigel or jointly with CG, to make, have made, use, sell, offer for sale and import products, and otherwise exploit the Program Technology, in each case for purposes solely within the CG Program Field, and (z) a royalty-free, exclusive, worldwide license, with the right to grant and authorize sublicenses, under any Information and intellectual property created by Rigel (solely or jointly with Novartis) under the Novartis Angiogenesis Collaboration, to make, have made, use, sell, offer for sale and import Therapeutic Candidates within the CG Program Field; and

(ii) subject to rights previously granted to third parties, a royalty-free, non-exclusive, worldwide license, with the right to grant sublicenses, under Rigel’s right, title and interest in and to all Patents with priority dates prior to the Effective Date that claim Therapeutic Candidates, or the manufacture or use thereof, to make, have made, use and sell products in Gene Therapy incorporating such Therapeutic Candidates.

(c) In addition, Rigel hereby grants to CG (i) a royalty-free, non-exclusive license, with the right to sublicense to CG Collaboration Partners, under Rigel’s right, title and interest in the Targets to make and use the Targets solely for the research and development of the Therapeutic Candidates in the Field of Research, and (ii) a royalty-free, non-exclusive license, with the right to sublicense to CG Collaboration Partners, under any Information and intellectual property created by Rigel (solely or jointly with Novartis) under the Novartis Angiogenesis Collaboration, to make and use the Targets solely for the research and development of the Therapeutic Candidates in the Field of Research. For clarity, it is understood and agreed that the licenses granted to CG under this Section 2.2 specifically exclude the performance by CG of research on or with a Target which is outside the Field of Research. Any sublicense granted hereunder to CG Collaboration Partners shall be limited to the purposes of such collaboration.

2.3 Rigel Covenant. Rigel hereby covenants that neither Rigel nor its Affiliates will make any claims against CG, its permitted sublicensees, distributors and customers in the chain of title with CG or its permitted sublicensees for Patent infringement as a result of activities which are explicitly permitted under the terms of this Agreement, nor shall Rigel or its Affiliates authorize a third party to make such a claim, and Rigel agrees to cooperate with CG in the defense against any such claim by licensees of Rigel.

2.4 Molecules That Are Both Targets and Therapeutic Candidates. With respect to each particular protein, peptide or Genetic Material that is both a Target and a Therapeutic Candidate (each a “Dual Molecule”), the parties agree that (i): CG shall have (y) the exclusive right to research, develop, make, have made, use, sell, offer for sale and import such Dual Molecule (including homologues and derivatives of such Genetic Material) as a therapeutic agent or such Dual Molecule (including homologues and derivatives of such Genetic Material) for Gene Therapy, and (z) to make and use such Dual Molecule in accordance with Sections 2.2(b) and (c); and (ii) Rigel shall have the exclusive right to research, develop, make, have made and use such Dual Molecule for the purposes set forth in Section 2.1(b)(i); and (iii) Rigel shall have the exclusive right to research, develop, make, have made and use such Dual Molecule for the purposes set forth in Section 2.1(b)(ii). For the sake of clarity, CG’s exclusive rights as described in this Section 2.4 shall not be construed to exclude Rigel or its permitted licensees from making and using such molecule as a target in research to elucidate protein or other signal transduction pathways in which such Dual Molecule is involved, or to discover, generate, develop and commercialize proteins, peptides, antibodies, Screened Genetic Material, other biological agents and synthetic organic molecules that may or may not modulate the activity of such Target or pathways but are not themselves Therapeutic Candidates. All activities of Rigel with respect to the use of Targets shall remain subject to the provisions of Section 3.5.

2.5 No Other License. No right or license is granted by either Party to the other under any other intellectual property other than those items expressly included in the licenses granted in this Article 2. Accordingly, no license shall be deemed granted by implication, estoppel or otherwise, if such license is not expressly and specifically granted in this Article 2.

ARTICLE 3

The Parties shall form a research management committee (the “RMC”) comprised of four (4) individuals, two (2) being Rigel employees appointed and replaced by Rigel at its discretion, and two (2) being CG employees appointed and replaced by CG at its discretion. The size and composition of the RMC may be modified by mutual agreement of the Parties. The RMC shall evaluate the results of the Research set forth in the research reports pursuant to Section 3.4(a) to assess whether a peptide, protein or Genetic Material is a Therapeutic Candidate, and perform such other duties as specifically delegated to the RMC by mutual written agreement of the Parties.

3.3 RMC Meetings and Actions. RMC meetings shall take place at such times and places as shall be determined by the RMC in order for the RMC to fulfill its obligations under Section 3.2. It is expected that the meetings will alternate between appropriate offices of each Party, or at such other convenient locations as agreed. If agreed by its members, the RMC may conduct meetings by telephone or video conference or other acceptable electronic means, provided that any decisions made during such meeting are recorded in writing and confirmed by signature of at least one (1) of the RMC members from each of the Parties. All decisions of or actions taken by the RMC shall be by unanimous approval of all the members of the RMC, and voting on any matters shall be reflected in the minutes of the meeting at which the vote was taken. If the RMC is unable to reach unanimous decision on any particular matter or issue, such matter or issue shall be referred to the chief executive officer of each Party or their designees for resolution. It is understood that, for purposes of determining the Parties’ rights and obligations under this Agreement, the authority of the RMC shall be limited to deciding those specific issues specifically delegated to the RMC in other Articles of this Agreement (i.e., other than the general matters described in this Article 3).

3.4 Reports; Disclosure.

(a) Rigel shall keep CG fully informed of the progress and results of the Research (including the discovery of Targets and/or Therapeutic Candidates made through its Research under the Novartis Angiogenesis Collaboration) and shall provide written reports at or before each RMC meeting describing its activities, the level of effort applied to, and the results of, the Research, specifically including Rigel’s determination as to which peptides, proteins or Genetic Material as of the date of such report meet the Success Criteria. Such RMC reports shall be in such form and contain such detail as the RMC shall determine. Rigel agrees to fully disclose to CG the Program Technology and the Targets, and to provide CG with reasonable quantities of Targets and Therapeutic Candidates generated or utilized in connection with the Research.

(b) Rigel agrees to maintain records of its activities in performing the Research, in good scientific manner, and to permit CG to have access to such records upon ten (10) days written notice to Rigel and during regular business hours, to the extent reasonably necessary to verify that Rigel has met its obligations under this Section 3.4.

3.5 Exclusivity of Efforts. Except as explicitly set forth in this Section 3.5, Rigel agrees that neither Rigel nor any of its Affiliates shall directly or indirectly conduct or sponsor any research, develop or otherwise commercialize any products or technologies within the Field of Research, other than pursuant to the Research Plan, during the Research Period and for a period of one (1) year following the Research Period. Without limiting the foregoing, Rigel shall not appoint or license any third party to develop, market, sell or otherwise distribute such products until after the expiration of one (1) year following the Research Period. Notwithstanding the foregoing in this Section 3.5 and subject toSection 2.1(b), Rigel shall be entitled to enter into the Novartis Angiogenesis Collaboration.
