The Parties agree to use commercially reasonable efforts to develop Collaboration Lead Compounds for use in the Field, making use of each Party's special expertise as directed by the RMC with the intent of obtaining all worldwide approvals or authorizations necessary for the manufacture, distribution, use or sale of a Product in the Territory ("Regulatory Approval") and bringing Products to the market as soon as reasonably practicable thereafter. [ * ] = 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 406 of the Securities Act of 1933, as amended. 7. <PAGE> b. Designation of Collaboration Lead Compound. (i) From time to time either Party may propose to the RMC one or more Lead Compounds suitable for Pre-Clinical Development. The RMC will promptly determine whether such Lead Compound is suitable for Pre-Clinical Development by determining whether such Lead Compound meets relevant criteria set forth by the RMC from time to time (the "Pre-Clinical Development Criteria"). (ii) If the RMC determines that such Lead Compound meets the Pre- Clinical Development Criteria, then within [ * ] of such determination each Party shall provide to the RMC a written notice as to whether it elects to participate in and, subject to Section 3(f), commit resources to conduct Pre- Clinical Development of such Lead Compound as a Collaboration Lead Compound according to the proposed plan and budget. If the RMC determines that such Lead Compound does not meet the Pre-Clinical Development Criteria, then within [ * ] of such determination each Party shall provide to the RMC a written notice as to whether it elects to designate such Lead Compound as a Collaboration Lead Compound and participate in and commit resources to conduct Pre-Clinical Development of such Collaboration Lead Compound notwithstanding that such Lead Compound does not meet the Pre-Clinical Development Criteria. If each Party makes an affirmative election with respect to any Lead Compound pursuant to either the first or second sentence of this Section 3(b)(ii), such Lead Compound shall be designated a "Collaboration Lead Compound" and, if an IND or equivalent is filed thereon, a "Product." If one Party makes an affirmative election and the other Party makes a negative election with respect to any Lead Compound being designated a Collaboration Lead Compound, the Party making an affirmative election will have the right to proceed independently to develop such compound as an Independent Lead Compound or Independent Product under Section 3(m). (iii) If neither Party makes an affirmative election with respect to any Lead Compound being designated a Collaboration Lead Compound under Section 3(b)(i), such Lead Compound shall be neither a Collaboration Lead Compound nor a compound that may be developed under Section 3(m), and development of such non- elected Lead Compound (a "Discontinued Compound") may be subsequently initiated by a Party by notifying the other Party of its interest in initiating Development of such Discontinued Compound at any time on or before [ * ] of the date of termination or expiration of the Research Program Term. If the other Party indicates it is not interested in initiating Development of such Discontinued Compound, the initiating Party may proceed with development of such Discontinued Compound as an Independent Lead Compound or an [ * ] = 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 406 of the Securities Act of 1933, as amended. 8. <PAGE> Independent Product and the initiating Party shall be deemed to be the Independent Party, pursuant to Section 3(m). At any time after [ * ] of the date of termination or expiration of the Research Program Term, either Party may, upon written notice to the other Party, proceed with development of a Discontinued Compound as an Independent Product and such Party shall be deemed to be the Independent Party, pursuant to Section 3(m). (iv) If a Lead Compound is not, at any time, presented to the RMC pursuant to Section 3(b)(i), such Lead Compound shall be neither a Collaboration Lead Compound nor a compound that may be developed under Section 3(m), and this Section 3(b)(iv) shall govern any future development of such non-proposed Lead Compound (a "Non-Proposed Compound"). If at any time on or before [ * ] of the date of termination or expiration of the Research Program Term, a Party hereunder (the "Non-Proposed Compound Interested Party") determines to initiate Pre-Clinical Development of such Non-Proposed Compound, it shall provide written notice to the other Party of such interest and the reasons therefor. The other Party will then have [ * ] to indicate whether it also is interested in the development of such Non-Proposed Compound. If the other Party is so interested, the Parties will proceed with Pre-Clinical Development or Development of such Non-Proposed Compound as a Collaboration Lead Compound pursuant to the terms of this Agreement. If the other Party is not so interested, the Non-Proposed Compound Interested Party may proceed with development of such Non-Proposed Compound as an Independent Product and the Non-Proposed Compound Interested Party shall be deemed to be the Independent Party, pursuant to Section 3(m). At any time after [ * ] of the date of termination or expiration of the Research Program Term, either Party may, upon written notice to the other Party, proceed with development of a Non-Proposed Compound as an Independent Product and such Party shall be deemed to be the Independent Party, pursuant to Section 3(m). c. Pre-Clinical Development. The Parties, under the direction of the RMC shall conduct Pre-Clinical Development with respect to any designated Collaboration Lead Compound. The costs of conducting such Pre-Clinical Development shall be shared by the Parties as set forth in Section 3(f). Under no circumstances shall either Party conduct studies of any Collaboration Lead Compound in the Field except as permitted by the RMC. d. Collaborative Development of Products. The Parties will each diligently collaborate in the Pre-Clinical Development and Development and use commercially reasonable efforts to develop and bring Products to the market as [ * ] = 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 406 of the Securities Act of 1933, as amended. 9. <PAGE> soon as reasonably practicable. The role of each Party in the Development process will be determined by the JDC, with the Parties intending that each Party will provide advisory and supporting services with respect to each phase of the process in which such Party is not actively or primarily involved. [ * ] shall supply [ * ] for each Product to be promoted or co-promoted by the Parties in the Territory in the aggregate, as determined by the JDC. A Party's required Development effort is hereinafter referred to as its "Required Development Effort". The JDC will determine appropriate written standards for measuring Required Development Efforts and accounting procedures to confirm and document each Party's performance of its Required Development Effort for any Product before the Parties commence Development thereof. No clinical trials involving any Product shall be commenced by or on behalf of either Party without the prior approval of the JDC. Nothing contained in this Section 3(d) shall be deemed to preclude either Party from terminating its participation in the collaborative Development, pursuant to Section 3(l), at such time. Any decision by a Party not to participate in development pursuant to Section 3(b) or to terminate participation in the collaborative Development pursuant to Section 3(l) shall not be deemed a breach of this Agreement. e. Development Plan and Development Budget. Promptly following the designation of a Collaboration Lead Compound pursuant to Section 3(b), the JDC shall initiate preparation of the development plan for the Development (the "Development Plan") and a budget (the "Development Budget") for proposed Development Costs (as defined in Section 3(f)). The initial Development Plan shall set time lines and priorities for the various Development activities through [ * ] and identify which Party, or whether a Third Party, is to be responsible for each activity. The budget for each development program shall include a detailed short-term budget covering all proposed Development Costs of the program expected during the subsequent [ * ] (the "Short-Term Budget Period") of the Development process. Both Parties recognize that the Development Plan and the Development Budget represent projections only and will be subject to frequent changes. Each such Development Plan and Development Budget shall be updated as deemed appropriate by the JDC, but in no event less frequently than [ * ] and approved by the JDC not later than thirty (30) days prior to each [ * ] of each applicable calendar year. f. Funding of Pre-Clinical Development and Development. Tularik shall be responsible for [ * ] of the Development Costs and JT shall be responsible for [ * ] of such Development Costs. "Development Costs" shall mean all costs and expenses reasonably charged directly to the Pre-Clinical Development of any Lead Compound, Collaboration Lead Compound or Development of any Product, as well as [*] of the functions that directly support such Pre- Clinical Development or Development (as calculated in accordance with GAAP and using the same allocation methods that the Party incurring such costs uses throughout its operations, but in all events [*], all as specified in the Development Plan and the Development Budget. Development Costs shall consist of the costs of [*] and [*] but shall exclude the costs of [*] to the extent such costs are incurred in connection with activities provided in Section [*]. Such costs shall include, without limitation: (i) the [*] for the [*] used in such Development (including [*], to the extent [*]; (ii) direct costs for [*], including, but not limited to, [*]; (iii) direct charges for materials (including [*]; (iv) labor and materials costs incurred in connection with [*]; and (v) labor and materials costs for the [*]. [ * ] = 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 406 of the Securities Act of 1933, as amended. 10. <PAGE> In the event the Development Costs incurred by a Party during any calendar quarter exceed [ * ] of the Development Costs set forth in the most recently approved Development Budget for activities to be conducted by such Party during such quarter (the "Overage Threshold"), then the other Party shall not be responsible for paying [ * ] share of any Development Costs in excess of the Overage Threshold incurred by the Party triggering such overage unless such overage had been approved in advance, or is subsequently ratified, unanimously by the JDC (in which case each of the Parties shall be responsible for [ * ] of all such Development Costs). In the event such overage has not been approved or ratified unanimously by the JDC, the Party incurring Development Costs exceeding the Overage Threshold in such quarter shall be responsible for [ * ] of the Development Costs in excess of the Overage Threshold. g. Scientific FTE. In preparing the Development Budget and determining Development Costs, the Parties will use a rate of [ * ] per Scientific FTE. "Scientific FTE" means the fully-loaded costs, including [ * ], but excluding [ * ], of employing a full-time scientific/technical person (or, in the case of less than a full-time dedicated person, the full-time equivalent scientific/technical person year) dedicated to the Pre-Clinical Development or Development for a period of one (1) year, [ * ]. Such rate shall be adjusted annually (utilizing the cost-breakdown and methodology attached hereto as Appendix E as the basis for such adjustment) and [ * ]. h. Payment of Development Costs. Each Party shall be responsible for paying [ * ] Development Costs incurred pursuant to the Development Plan and the Development Budget as provided in Section 3(f), subject to reimbursement as provided herein. Within thirty (30) days after each calendar quarter, each Party shall provide the JDC with detailed information concerning the Development Costs incurred by such Party during such quarter. Promptly after receipt thereof, the JDC will determine the amount, if any, which either Party has paid in excess of the amount to be borne by such Party for such quarter pursuant to Section 3(f) (an "Overpayment"), and shall so notify the Parties. In the event of an Overpayment, the other Party shall pay the amount thereof to the Party making the Overpayment within thirty (30) days after receipt of notice from the JDC that an Overpayment has occurred. [ * ] = 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 406 of the Securities Act of 1933, as amended. 11. <PAGE> i. Drug Approval Applications. Consistent with the Development Plan and Development Budget and as directed by the JDC, the Parties will file applications for regulatory approval required before commercial sale or use of a Product as a drug in a country within the Territory ("Drug Approval Applications") and attempt to obtain regulatory approvals in each country in the Territory in which the Parties either individually or jointly intend to commercialize Products. JT will be responsible for filing in its name and shall own all regulatory submissions relating to Products including, without limitation, all INDs and NDAs, in each country in the JT Territory, in which Products will be commercialized. Tularik will be responsible for filing in its name and shall own all regulatory submissions, including, without limitation, all INDs and NDAs in each country in the Tularik Territory in which Products will be commercialized by Tularik. The JDC will be responsible for designating a Party to be responsible for filing all regulatory submissions in each country in the Co-Promotion Territory in which Products will be commercialized. The Party not responsible for filing regulatory submissions for Products in a country pursuant to this Agreement shall have a right to cross-reference to all such filings made by the other Party in any country. The Parties will cooperate in the preparation of all such regulatory filings and in obtaining Regulatory Approvals under this Section 3(i). j. Line Extensions. JT and Tularik may each prepare and submit to the JDC for consideration plans for development of Product line extensions and the conduct of clinical trials covering indications other than those for which Products are being developed or commercialized in the Territory. Any such line extensions or any additional clinical trials for additional indications will be subject to the approval and supervision of the JDC as part of the ongoing Development of such Product. k. Compliance. The Parties will comply with all supranational, federal, state and/or local laws pertaining to the Development and commercialization of Products. l. Termination of Participation in Collaborative Development. On a Collaboration Lead Compound-by-Collaboration Lead Compound basis, either Party may elect (upon [ * ] written notice following receipt by the Party contemplating termination of its participation in the Pre-Clinical Development of any Collaboration Lead Compound or Development of any Product of Development Termination Documents) to terminate its participation in, or to not to participate in, the Pre-Clinical Development of any Collaboration Lead Compound or Development of any Product. "Development Termination [ * ] = 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 406 of the Securities Act of 1933, as amended. 12. <PAGE> Documents" shall mean the following documents or reports: [ * ]. After receipt of such notice by the other Party, the Party providing such notice shall no longer be responsible for bearing further Development Costs for such Collaboration Lead Compound or Product as specified herein, in which event the other Party will have the right to proceed independently to develop such Collaboration Lead Compound or Product as an Independent Lead Compound or Independent Product, pursuant to Section 3(m). In the event a Party gives notice under this Section 3(l), such non-Independent Party (i) will remain responsible for its share of Development Costs for such Collaboration Lead Compound or Product until [ * ] from the date the other Party receives such notice, and (ii) will make its personnel, relevant data and other resources available to the Independent Party as necessary to effect an orderly transition of development responsibilities, with the costs of such personnel, relevant data and resources to be borne by [ * ]. The Parties each recognize and agree that a non- Independent Party's termination of participation in Pre-Clinical Development or Development in accordance with this Section 3(l) will not be considered a breach of its obligations under this Agreement.

The MC will determine appropriate written standards for measuring and accounting procedures to confirm and document each Party's performance of its Required Sales Effort, [ * ] after the filing of the NDA for any Product. Nothing contained in this Section 5(d) shall be deemed to preclude either Party from relinquishing its right to participate in the co-promotion of Products in the Co-Promotion Territory pursuant to Section 5(c), at any time.

I enclose for your review certain changed pages. Due to some redlining errors in the draft sent to you on September 24, 1998, the attached changed pages are marked against the draft sent on September 21, 1998. While this approach may result in your having to re-read some provisions that you have already reviewed, it will avoid the possibility that changes in the September 24, 1998 draft were not read because they were not marked. In addition, I set forth below the logic that permits the [ * ] able to commercialize [ * ] resulting from the collaboration with Tularik in the JT Territory.
