RESEARCH AND DEVELOPMENT COLLABORATION 2.1 OVERVIEW. The primary purpose of the Collaboration is to conduct Research and Development toward the discovery and development of Collaboration Products in accordance with the Annual Research Plan. To that end, it is contemplated by the parties that: (a) Neurocrine will have primary responsibility for supplying certain cell lines necessary for the study of glial cell activation, providing small molecule compounds from the Neurocrine Chemical Library, performing limited medicinal chemistry as required by the Annual Research Plan, and conducting certain screening and secondary assays and screening compounds from the Neurocrine Chemical Library against Rigel Targets; (b) Neurocrine and Rigel will share responsibility for applying the Rigel Technology to develop an appropriate glial cell assay system to identify Protein Targets and Peptide Antagonists; and (c) Rigel will have primary responsibility for identifying and providing Protein Targets, identifying and sequencing gene(s) coding for the Protein Targets, and generating, identifying and providing Peptide Antagonists of such Protein Targets. Rigel will also have responsibility for providing Rigel Targets to Neurocrine for screening purposes. It is understood that the individual and joint responsibilities will be set forth in detail in the Annual Research Plan to be developed pursuant to Section 3.2. 2.2 IDENTIFICATION AND TRANSFER OF PROTEIN TARGETS. The parties shall use diligent efforts to identify and transfer to Neurocrine one or more "primary" Protein Targets that the Research Committee determines, based upon the activity of such target in glial cell function assays performed during the Research and Development, to be the best targets against which to screen small molecules for activity. To this end, within the first year of the Collaboration, Rigel shall use diligent efforts to identify and provide to Neurocrine at least six (6) Protein Targets, the genes encoding those Protein Targets, and Peptide Antagonists active against such Protein Targets, unless the Steering Committee otherwise provides in the Annual Research Plan. In the event that Rigel is unable, using such diligent efforts, to provide the Protein Targets, genes encoding the Protein Targets and/or Peptide Antagonists within the first year of the Collaboration, Rigel shall continue to use diligent efforts to provide such biological materials as soon as possible thereafter. 4. 2.3 TRANSFER OF DEVELOPMENT MOLECULE TECHNOLOGY. (a) Within the first year of the Collaboration, Rigel may provide to Neurocrine a maximum of three (3) Rigel Targets that Neurocrine shall screen against the Neurocrine Chemical Library. Similarly, during the second year of the Collaboration, Rigel may provide to Neurocrine a maximum of another three (3) Rigel Targets for the purposes of screening against the Neurocrine Chemical Library. In no instance shall Neurocrine be obligated to screen a Rigel Target that it believes in good faith to be in direct competition with a Neurocrine research and development program existing at the time of the request. All Rigel Targets shall be formatted in 96-well plates in an assay suitable for high throughput screening. Within six (6) months of receipt of a Rigel Target, Neurocrine shall screen such Rigel Targets as directed by the Research Committee and provide Rigel with the results of such screen. In the event Rigel provides more than two Rigel Targets to Neurocrine in any sixty (60) day period, Neurocrine shall have the right to extend the time period within which it must provide the results of the screen by an additional sixty (60) days. (b) Based upon the results of the foregoing screening activities, Rigel may select one (1) Rigel Target in each of the two years of the Research and Development Period. During the second year of the Collaboration, Neurocrine shall devote one full-time equivalent (FTE) for the purpose of performing medicinal chemistry on molecules in the Neurocrine Chemical Library that the Research Committee determines are active against the Rigel Target and most suitable for structure-activity relationship development, and perform additional appropriate screening to provide Rigel with a Development Molecule prior to expiration of the Research and Development Period. Once a Development Molecule has been identified, Neurocrine shall no longer be obligated to expend any additional effort or resources on such Rigel Target or Development Molecule. In the event that Neurocrine, in its discretion, determines that it is unable to devote the services of one full-time equivalent (FTE) to such medicinal chemistry activities during the second year of the Collaboration, Neurocrine may elect to provide Rigel with a portion of the Neurocrine Chemical Library (hereinafter the "Sample Library") in lieu of the performance of such services. The Sample Library shall consist of approximately one hundred microliters (100 uL) of a ten millimolar (10mM) stock solution of any compound then existing in the Neurocrine Chemical Library, for which Neurocrine has in its possession a quantity of at least 2 milligrams, on a compound-by-compound basis. The Sample Library shall also include any structural information Neurocrine has in its possession with regard to the transferred compounds. At the end of the second year of the Collaboration (or earlier as provided above), Neurocrine shall provide to Rigel the Sample Library to allow Rigel to conduct internal screening activities, excluding the screening of any targets which Neurocrine is, or reasonably anticipates, itself screening, as determined at the time of transfer. For purposes of clarity, at the time of transfer Neurocrine shall provide Rigel with a list of the targets as to which screening of the Sample Library is prohibited. 2.4 CONDUCT OF RESEARCH AND DEVELOPMENT. The parties will conduct their respective Research and Development activities under the Annual Research Plan in good 5. scientific manner and in compliance with all applicable governmental, regulatory and legal requirements. Neurocrine and Rigel will each use their good faith scientific and business judgment to allocate sufficient time, effort, equipment and facilities to. the Collaboration to achieve the objectives of the Collaboration consistent with the terms of this Agreement and the recommendations of the Steering Committee, as provided in Section 3 below. 2.5 VISIT OF FACILITIES. Representatives of either party may, upon reasonable notice and at a frequency reasonably acceptable to the Other party during normal business hours (a) visit the facilities where the Research and Development is being conducted; and (b) consult informally, during such visits and by telephone, with personnel of the other party performing the Research and Development. Each party shall bear its own expenses with regard to any such visits. If requested by the other party, Neurocrine and Rigel shall cause appropriate individuals working on the Research and Development to be available for meetings at the location of the facilities where such individuals are employed at times reasonably convenient to each party. 2.6 DISCLOSURE OF DATA. The parties will promptly provide to each other all data generated during the Research and Development, including, without limitation, all Neurocrine Technology, Joint Technology and Rigel Technology arising during the Research and Development Period. 3. STEERING COMMITTEE 3.1 FORMATION.

Neurocrine will not be subject to any liability for any settlement of such Claims made by a Rigel Indemnitee without Neurocrine's consent (not to be unreasonably withheld). The Rigel Indemnitee may retain separate counsel with respect to any such Claims at its own expense. 9.2 DISCLAIMER OF WARRANTIES. THE RIGEL TECHNOLOGY AND THE NEUROCRINE TECHNOLOGY ARE PROVIDED BY RIGEL AND NEUROCRINE, RESPECTIVELY, "AS IS" AND EACH PARTY EXPRESSLY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, NONIFRINGEMENT OF THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES OR ARISING FROM A COURSE OF DEALING, USAGE OR TRADE PRACTICES WITH RESPECT THERETO. Without limitation, each party expressly does not warrant the success of any Research and Development activities or the safety or usefulness of any technology it provides hereunder. 9.3 DISPUTE RESOLUTION. If a dispute arises between the parties relating to the interpretation or performance of this Agreement or the grounds for the termination thereof, the parties agree to hold a meeting, attended by individuals with decision-making authority regarding the dispute, to attempt in good faith to negotiate a resolution of the dispute prior to pursuing other available remedies. If, within 30 days after such meeting, the parties have not succeeded in negotiating a resolution of the dispute, such dispute shall be submitted to final and binding arbitration under the then current Licensing Agreement Arbitration Rules of the American Arbitration Association ("AAA"), with a panel of three arbitrators with significant experience in the biopharmaceutical industry conducting proceedings in San Diego, California. Such arbitrators 14. shall be selected by mutual agreement of the parties or, failing such agreement, shall be selected according to the aforesaid AAA rules. The parties shall bear the costs of arbitration equally unless the arbitrators, pursuant to their right, but not their obligation, require the non-prevailing party to bear all or any unequal portion of the prevailing party's costs. The decision by the arbitrators shall be made within ninety (90) days after the selection of the arbitrators. The decision of the arbitrators shall be final and may be sued on or enforced by the party in whose favor it decides in any court of competent jurisdiction at the option of such party. The arbitrators will be instructed to prepare and deliver a written, reasoned opinion conferring their decision. The rights and obligations of the parties to arbitrate any dispute relating to the interpretation or performance of this Agreement or the grounds for the termination thereof shall survive the expiration or termination of this Agreement for any reason. 9.4 FORCE MAJEURE. Neither party shall be held liable or responsible to the other party nor shall either party be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than payment of monies due) when such failure or delay is caused by or results from causes beyond reasonable control of the affected party including but not limited to fire, floods, embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any governmental authority, or earthquakes, provided that the affected party uses reasonable efforts to overcome such failure or delay. 9.5 ASSIGNMENT. This Agreement may not be assigned or otherwise transferred, nor, except as expressly provided hereunder, may any rights or obligations hereunder be assigned or transferred, by either party without the written consent of the other party; provided, however, that either party may, without such consent, assign this Agreement and its rights and obligations hereunder (a) in connection with the transfer or sale of all or substantially all of its business, if such assets include substantially all of the assets relating to its performance of its obligations hereunder, (b) to a wholly owned subsidiary or, (c) in the event of its merger or consolidation with another company at any time during the term of this Agreement. Any purported assignment in violation of this Section 9.5 shall be void. Any permitted assignee shall assume all obligations of its assignor under this Agreement. 9.6 PUBLICITY. The parties agree that neither party will originate any news release or other public announcement, written or oral, or otherwise make any disclosure relating to the existence or terms of or performance under this Agreement without the prior written approval of the other party, except as may otherwise be required by law, or as provided in Section 7.4. 9.7 EXPORT LAWS. Each party hereby agrees that no technology or information licensed from the other, and no product thereof, will be made available or re-exported, directly or indirectly, except in compliance with all applicable export laws and regulations. 9.8 SEVERABILITY. Both parties hereby expressly agree and contract that it is the intention of neither party to violate any laws, rules, regulations, treaty or decision of any 15. government agency or executive body thereof of any country or community or association of countries. Should a court or governmental authority of competent jurisdiction determine that one or more provisions of this Agreement are invalid or unenforceable by reason of such a violation, then the parties hereto shall attempt to substitute, by mutual consent, valid provisions for such invalid provisions, which valid provisions closely approximate the economic effect of the invalid provisions. If the parties are unable to formulate a mutually acceptable provision to replace any invalid provision, then such invalid provisions shall be severed from this Agreement and the invalidity of such provision shall not affect the validity of the Agreement as a whole. 9.9 NOTICES. Any notice or report required or permitted to be given or made under this Agreement by one of the parties hereto to the other shall be in writing, delivered personally or by facsimile (and promptly confirmed by telephone, personal delivery or courier) or courier, postage prepaid, addressed to such other party at its address indicated on the first page of this Agreement (to the attention of Gary Lyons, if to Neurocrine, and to the attention of James Gower, if to Rigel), or to such other address as the addressee shall have last furnished in writing to the address or and shall be effective upon receipt by the addressee. 9.10 APPLICABLE LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of California, without regard to its choice of law provisions, and any applicable laws of the United States. 9.11 ENTIRE AGREEMENT; AMENDMENT. This Agreement contains the entire understanding of the parties with respect to the subject matter hereof. All express or implied agreements and understandings, either oral or written, heretofore made are expressly merged into and made a part of this Agreement. This Agreement may be amended, or any term hereof modified, only by a written instrument duly executed by both parties hereto. 9.12 INDEPENDENT CONTRACTORS. It is expressly agreed that Neurocrine and Rigel shall be independent contractors and that the relationship between the two parties shall not constitute a partnership, joint venture or agency of any kind. Neither party shall have the authority to make any statements, representations or commitments of any kind, or to take any action, which shall be binding on the other, without the prior written authorization of the other party to do so. 9.13 WAIVER. The waiver by either party hereto of any right hereunder or the failure to perform or of a breach by the other party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by said other party whether of a similar nature or otherwise. 9.14 COUNTERPARTS. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 16. IN WITNESS WHEREOF, the parties hereto have duly executed this Collaborative Agreement. NEUROCRINE, INC. RIGEL, INC. By: /s/ Kevin C.
