corporation with its principal place of business at 10555 Science Park Road, San Diego, California 92121-1102 ("Neurocrine") and American Home Products Corporation, acting through its Wyeth-Ayerst Laboratories Division, a Delaware corporation, with a place of business at 555 East Lancaster Avenue St. Davids Pennsylvania 19087 ("Wyeth-Ayerst"). WHEREAS, Wyeth-Ayerst is engaged in the research, development and commercialization of human pharmaceutical products; WHEREAS, Neurocrine is the owner or licensee of certain patent rights relating to [***] which may be useful in the discovery and development of human pharmaceutical products; WHEREAS, Wyeth-Ayerst and Neurocrine have agreed to collaborate, on the terms and conditions set forth herein, in the research, development and commercialization of compounds [***] (each as defined below); NOW, THEREFORE, in consideration of the mutual representations, warranties and covenants contained herein and other good and valuable consideration, the Parties agree as follows: ARTICLE ONE DEFINITIONS When used in this Agreement, each of the following capitalized terms shall have the meanings set forth in this Article One. Any terms defined elsewhere in this Agreement shall be given equal weight and importance as though set forth in this Article One. 1.1 "Acquisition" shall mean with respect to Neurocrine, the acquisition, directly or indirectly, by any Third Party of (i) securities authorized to cast fifty percent (50%) or more of the votes in any election of directors and/or (ii) the sale or other transfer of all or substantially all of its assets. Notwithstanding the foregoing, the sale or other transfer of substantially all of the assets of Neurocrine to another direct or indirect wholly-owned subsidiary of Neurocrine shall not constitute an Acquisition. 1.2 "Affiliate" shall mean a Person that, directly or indirectly, through one or more intermediates, controls, is controlled by, or is under common control with the Person specified. For the purposes of this definition, control shall mean the direct or indirect ownership of, (a) in the case of corporate entities, securities authorized to cast more than fifty percent (50%) of the votes in any election for directors or (b) in the case of non-corporate entities, more than fifty percent (50%) ownership interest with the power to direct the management and policies of such non-corporate entity. Notwithstanding the foregoing, the term "Affiliate" shall not include subsidiaries in which a Party or its Affiliates owns a majority of the ordinary voting power to elect a majority of the board of directors, but is restricted from electing such majority by contract or otherwise, until such time as such restrictions are no longer in effect. 1.3 "Collaboration Products" shall mean products containing one or more Lead Compounds as an active ingredient(s), provided, however, that if (i) none of the Compounds contained in a product are encompassed within the Collaboration Technology and (ii) such product is not developed by Wyeth-Ayerst, its Affiliates or sublicensees for any indication in which the [***] and (iii) identification, development and commercialization of such product does not utilize Collaboration Technology, then such product shall not be a Collaboration Product for purposes of this Agreement. For the purposes of License Fees under Article Eight below and Royalty payments under Article Nine below, all formulations (e.g., tablets, gel caps, topical formulations, parenteral formulations, sustained release formulations, etc.) of a Collaboration Product will be considered to be the same Collaboration Product, regardless of the indications for which such Collaboration Product may be used. 1.4 "Collaboration Technology" shall mean all Technology encompassed by the Neurocrine Technology, Wyeth-Ayerst Technology and Joint Technology. 1.5 "Combination Product" shall mean a product that contains, as active ingredients one or more Lead Compounds (or Collaboration Products) and one or more other Compounds that are not Lead Compounds (or Collaboration Products). 1.6 "Commercially Reasonable Efforts" shall mean efforts and resources commonly used by a Party (which efforts will be no less than those used by such Party in the research and development of its products, as described below, in the one year period preceding the Effective Date) for a product owned by it or to which it has rights, which product is at a similar stage in its development or product life and is of similar market potential taking into account efficacy, safety, Regulatory Authority approved labeling, the competitiveness of alternative products in the marketplace, the patent and other proprietary position of the product, the likelihood of Regulatory Approval given the regulatory structure involved, the profitability of the product including the royalties payable to licensors of patent rights, alternative products and other relevant factors. Commercially Reasonable Efforts shall be determined on a market-by-market basis for a particular product, and it is anticipated that the level of effort will change over time, reflecting changes in the status of the Collaboration Product and the market involved. 1.7 "Competition" shall exist during a given calendar quarter with respect to a Collaboration Product in a county if, during such calendar quarter, one or more Competitive Products shall be commercially available in such country and shall have in the aggregate a [***] or greater share of the total market (based on data provided by IMS International, or if such data are not available, based on such other data mutually agreed to by Wyeth-Ayerst and Neurocrine) in that country as measured by unit sales. For purposes of this agreement, the "total market" in a country shall be the sum of (x) the number of units of the affected Collaboration Product sold during such calendar quarter in such country by Wyeth-Ayerst, its Affiliates and sublicensees and (y) the number of units of Competitive Products sold in such country during such calendar quarter. 1.8 "Competitive Products" shall mean and include products (other than Collaboration Products developed and commercialized by Wyeth-Ayerst pursuant to this Agreement) that contain principally the same active chemical entity(ies) as a Collaboration Product and which (a) act through the same mechanism as a Collaboration Product and (b) can reasonably be or are reasonably used for the same indication as a Collaboration Product. Without limitation of the foregoing, compounds that are of the same general formulation type (i.e., oral vs. parenteral vs. topical) as a Collaboration Product would generally be considered Competitive Products while compounds of a different general formulation type from a Collaboration Product would generally not be considered Competitive Products unless the compound and Collaboration Product are reasonably used (other than de minimis usage) for the treatment of the same indication. 1.9 "Compound" shall mean a chemical compound or substance together with all complexes, mixtures and other combinations, prodrugs, metabolites, enantiomers, salt forms, racemates, and isomers thereof. 1.10 "Confidential Information" shall mean with respect to each Party, non-public proprietary data or information which belong in whole or in part to such Party and/or information designated as Confidential Information of such Party hereunder. 1.11 "Controls" or "Controlled" shall mean with respect to Technology, the possession of the ability to grant licenses or sublicenses without violating the terms of any agreement or other arrangement with, or the rights of, any Third Party. 1.12 "Default" shall mean with respect to a Party that (i) any representation or warranty of such Party set forth herein shall have been untrue in any material respect when made or (ii) such Party shall have failed to perform any material obligation set forth in this Agreement. 1.13 [***] shall be as defined in Exhibit A. 1.14 "Effective Date" shall mean January 1, 1999. 1.15 "European Union" shall mean, from time to time, those countries that are members of the European Union. 1.16 "FDA" shall mean the Federal Food and Drug Administration of the United States Department of Health and Human Services or any successor agency thereof. 1.17 "Field of Use" shall mean all therapeutic, prophylactic and diagnostic uses. 1.18 "FTE" shall mean full time equivalent scientific person year consisting of a minimum of a total [***] per year of scientific work on or directly related to the Research Program.

[***]. In addition, [***]. Notwithstanding the foregoing, in the event Wyeth-Ayerst shall make the decision [***], ICE shall be deemed to have been met. 1.23 "IND" shall mean an Investigational New Drug Application covering a Collaboration Product filed with the FDA pursuant to 21 CFR 312.20 or an equivalent foreign filing required for the clinical testing of a pharmaceutical product. 1.24 "Joint Confidential Information" shall mean Confidential Information owned jointly by Wyeth-Ayerst and Neurocrine or otherwise designated as Joint Confidential Information hereunder. 1.25 "Joint Inventions" shall be as defined in Section 13.1 hereof. 1.26 "Joint Technology" shall mean Technology, which is discovered or invented jointly by Neurocrine personnel and Wyeth-Ayerst personnel during the term of this Agreement. 1.27 "Lead Compound(s)" shall mean those Compounds (i) [***], (ii) that meet the criteria set forth on Exhibit B hereto and (iii) that are selected by the Steering Committee or Wyeth-Ayerst in accordance with Article Six, provided, however, that Lead Compounds shall specifically exclude any Compounds [***]. Notwithstanding the foregoing, for purposes of calculating Net Sales and determining License Fees and Royalty payments under this Agreement, a Lead Compound together with all complexes, mixtures and other combinations, prodrugs, metabolites, enantiomers, salt forms, racemates, isomers, and derivatives thereof, shall be considered to be a single Lead Compound. 1.28 "License Fees" shall mean the payments to be made by Wyeth-Ayerst to Neurocrine upon occurrence of certain events as set forth in Article Eight. 1.29 "Major European Country" shall mean France, Germany, Italy or the United Kingdom. 1.30 "NDA" shall mean a New Drug Application (or Biologics License Application, if applicable) covering a Collaboration Product filed with the FDA pursuant to 21 CFR 314 or an equivalent foreign filing required for marketing approval of a pharmaceutical product. 1.31 "Net Sales" shall mean, with respect to a Collaboration Product, all proceeds actually received from the sale or other disposition of a Collaboration Product by Wyeth-Ayerst, its Affiliates or sublicensees to unrelated Third Parties, less the reasonable and customary deductions from such gross amounts actually paid by or charged to the account of Wyeth-Ayerst, including, without limitation, (a) trade, cash and quantity discounts actually allowed and taken directly with respect to such sales; (b) amounts repaid, credits or allowances actually granted for damaged goods, defects, recalls, returns or rejections of Collaboration Product and retroactive price reductions; (c) sales or similar taxes actually paid by or charged to the account of Wyeth-Ayerst, its Affiliates or sublicensees without offset (including, without limitation, duties or other governmental charges levied on, absorbed or otherwise imposed on the sale of Collaboration Product, value added taxes or other governmental charges otherwise measured by the billing amount, when included in billing, but not including national, state or local taxes based on income); (d) charge back payments and rebates granted to (i) managed health care organizations, (ii) federal, state and/or local governments or their agencies, (iii) purchasers and reimbursers, or (iv) trade customers, including, without limitation, wholesalers and chain and pharmacy buying groups; and (e) freight, postage, shipping, customs duties and insurance charges to the extent included in the proceeds actually received from the customer. For the purposes of determining Net Sales hereunder, a sublicensee shall include a Third Party who, pursuant to an agreement with Wyeth-Ayerst, distributes Collaboration Products, provided, such Third Party also, as required by such agreement, conducts promotion and/or marketing activities in the applicable territory. Net Sales shall be determined in accordance with United States generally accepted accounting principles consistently applied. A "sale" shall also include the transfer or other disposition of a Collaboration Product for consideration other than cash, in which case such consideration will be valued at the fair market value thereof. In the event that a Collaboration Product is sold either for consideration other than cash or as part of a bundled product, the Net Sales of such Collaboration Product will be calculated based on the average unit price of such Collaboration Product when sold (other than as part of a bundle) in cash transactions in such country. In the event that, on a country-by-country basis, a Collaboration Product is sold in the form of a Combination Product, the Net Sales for such Combination Product will be calculated as follows: (i) If Wyeth-Ayerst, its Affiliates and/or sublicensees separately sells, in such country, (x) Collaboration Products containing as their sole active ingredient(s) the same Lead Compound(s) as are contained in such Combination Product and (y) other products containing as their sole active ingredient(s) the other active component or components in such Combination Product, the Net Sales attributable to such Combination Product shall be calculated by multiplying actual Net Sales of the Combination Product by the [***], which Collaboration Product contains, as the sole active ingredient(s), the same Lead Compound(s) as are in such Combination Product and [***], which product(s) contain, as their sole active ingredient(s) any other active component or components in the Combination Product. (ii) If Wyeth-Ayerst, its Affiliates and/or sublicensees separately sells, in such country, Collaboration Products containing as their sole active ingredient(s) the same Lead Compound(s) as are contained in such Combination Product but do not separately sell, in such country, other products containing as their sole active ingredient(s) the other active component or components in such Combination Product, the Net Sales attributable to such Combination Product shall be calculated by multiplying the Net Sales of such Combination Product by the [***], which Collaboration Product contains, as the sole active ingredient(s), the same Lead Compound(s) as are in such Combination Product, [***]. (iii) If Wyeth-Ayerst, its Affiliates and/or sublicensees do not separately sell, in such country, Collaboration Products containing as their sole active ingredient(s) the same Lead Compound(s) as are contained in such Combination Product, the Net Sales attributable to such Combination Product shall be calculated by multiplying the Net Sales of such Combination Product by the [***]. Notwithstanding the foregoing, Net Sales shall not include any consideration received by Wyeth-Ayerst, its Affiliates or sublicensees in respect of the sale, use or other disposition of a Collaboration Product in a country as part of a clinical trial prior to the receipt of all Regulatory Approvals required to commence full commercial sales of such Collaboration Product in such country. 1.32 "Neurocrine Ancillary Transporters" shall mean [***] as defined on Exhibit A. 1.33 "Neurocrine Compound" shall mean any Compound, which is (a) within the Neurocrine Proprietary Chemical Library, and (b) is screened under the Research Program for activity against the Neurocrine Transporters together with all complexes, mixtures and other combinations, prodrugs, metabolites, enantiomers, salt forms, racemates, and isomers thereof. 1.34 "Neurocrine Confidential Information" shall mean Confidential Information owned by Neurocrine or otherwise designated as Neurocrine Confidential Information hereunder but shall not include Joint Confidential Information. 1.35 "Neurocrine Invention" shall have the meaning set forth in Section 13.1 hereof. 1.36 "Neurocrine Materials" shall mean Neurocrine proprietary research materials including, but not limited to, Neurocrine Compounds, the Neurocrine Proprietary Chemical Library, assays, physical databases of chemical structures of Compounds in the Neurocrine Proprietary Chemical Library, reagents and materials derived therefrom.

In the event that a decision cannot be reached by the Steering Committee, the matter shall be referred to further review and resolution by the Chief Executive Officer of Neurocrine and President of Wyeth-Ayerst Research as set forth in Section 14.1. ARTICLE FIVE COLLABORATIVE RESEARCH PROGRAM AND RESEARCH FUNDING 5.1 Research Program. Under the terms and conditions set forth herein, Wyeth-Ayerst and Neurocrine will exclusively collaborate in the conduct of a collaborative pre-clinical research program (the "Research Program") to discover, identify and develop modulators of the Neurocrine Transporters for the treatment of central nervous system disorders, [***]. The Research Program will be focused on the screening of the Wyeth-Ayerst Proprietary Chemical Library and Neurocrine Proprietary Chemical Library and any other library selected by mutual agreement of the Parties for the identification of Hits, a medicinal chemistry program for the development of Lead Compound candidates, screening and testing of Lead Compound candidates to identify Lead Compounds and further preclinical research and screening of Lead Compounds to select Collaboration Products for development and commercialization by Wyeth-Ayerst. 5.2 Term. The initial term of the Research Program will be three (3) years unless earlier terminated in accordance with Article Twelve hereof. The initial term of the Research Program will begin on January 1, 1999. Upon the expiration of the initial three (3) year term, the term of the Research Program may, upon mutual written agreement of the Parties, be extended for [***] extension terms on substantially the same terms as those set forth herein. Notwithstanding the foregoing, in the event that at the end of the initial term of the Research Program, [***] and the Steering Committee or Wyeth-Ayerst has determined that significant additional [***] should be conducted and the Steering Committee determines that such additional [***] justifies extending the Research Program by an additional [***], the Parties will extend the term of the Research Program [***], provided, however, that in no event will Wyeth-Ayerst be obligated to fund more than [***] Neurocrine Researcher FTEs (at a rate of [***]) during [***]. 5.3 Research Plan. Within thirty (30) days following the date this Agreement is signed by each of the Parties and on an annual basis on or before October 31 of each year thereafter, the Steering Committee shall develop and approve, a research plan and budget for the collaborative Research Program (the "Research Plan"). The Research Plan will be updated on an annual basis and shall specifically include both detailed plans for the following year including staffing levels, activities and estimated expenditures as well as more general plans for the remaining term of the Research Program. The Research Plan may only be modified or amended upon the written approval of the Steering Committee. Except as expressly set forth in Section 5.5 below, each Party shall be responsible for its own costs and expenses incurred in their conduct of the Research Program. 5.4 Conduct of the Research Program. Neurocrine and Wyeth-Ayerst shall each use Commercially Reasonable Efforts to perform its obligations under the Research Program in accordance with the Research Plan. Notwithstanding, the foregoing, during the term of the Research Program, Neurocrine shall apply an average of at least [***] Neurocrine Researcher FTEs per year in performing its obligations under the Research Program, which minimum number of Neurocrine Researcher FTEs shall be increased to [***] upon the successful completion of the first [***] (according to the criteria set forth in Exhibit B, Part 2(a)) [***] Lead Compound (as defined in Exhibit B attached hereto) and to [***] upon the successful completion of the first [***] (according to the criteria set forth in Exhibit B, Part 2(b)) of [***] Lead Compound, provided, however, that neither increase shall become effective prior to the beginning of the [***] of the Research Program. While it is anticipated that Neurocrine and Wyeth-Ayerst will each devote to the Research Program efforts consistent with the goals set forth in the Research Plan, in no event will Neurocrine's failure to devote to the Research Program more than the number of Neurocrine Researcher FTEs funded by Wyeth-Ayerst pursuant to Section 5.5 below, in and of itself, constitute a failure by Neurocrine to use Commercially Reasonable Efforts to conduct the Research Program. In addition, the Parties have agreed that the Research Plan will at all times allocate to Neurocrine sufficient responsibilities to allow Neurocrine to devote to the Research Program, the number of Neurocrine Researcher FTEs funded by Wyeth-Ayerst hereunder. 5.5 Funding of the Research Program. (a) Funding by Wyeth-Ayerst. During the initial term of the Research Program, Wyeth-Ayerst will provide to Neurocrine the funds in the amount of [***] per calendar quarter, which funds are to be used by Neurocrine solely to fund the conduct of the Research Program by [***] Neurocrine Researcher FTEs. The funding amount set forth in the preceding sentence shall be increased to [***] per calendar quarter upon the successful completion of the first [***] (according to the criteria set forth in Exhibit B, Part 2(a)) [***] Lead Compound which funds are to be used by Neurocrine solely to fund the conduct of the Research Program by [***] Neurocrine Researcher FTEs and to [***] per calendar quarter upon the successful completion of the [***] (according to the criteria set forth in Exhibit B, Part 2(b)) of [***] Lead Compound [***] which funds are to be used by Neurocrine solely to fund the conduct of the Research Program by [***] Neurocrine Researcher FTEs, provided, however, that (i) neither increase shall become effective prior to [***] of the Research Program and (ii) subject to clause (i) above, each such increase shall become effective on the first day of the calendar quarter following the calendar quarter in which the event resulting in such increase occurs. Wyeth-Ayerst will provide the funding set forth in this Section 5.5(a) to Neurocrine [***] during the term of the Research Program, provided however, that the first payment will be due on [***] business day following the date the Parties shall have both signed this Agreement. (b) Reporting and Reconciliation. Within thirty (30) days after the end of each calendar quarter during the term of the Research Program, Neurocrine will provide to Wyeth-Ayerst a report setting forth the number of Neurocrine Researcher FTEs devoted to the Research Program in such calendar quarter along with their names and titles. In the event that Neurocrine shall, in any calendar quarter, devote to the conduct of the Research Program fewer than the number of Neurocrine Researcher FTEs funded by Wyeth-Ayerst for the such calendar quarter as required under Section 5.4 hereof, Neurocrine shall in good faith endeavor to devote, at its own expense, additional Neurocrine Researcher FTEs to the conduct of the Research Program in subsequent calendar quarters to make up for the shortfall. If, despite Neurocrine's good faith efforts to make up any shortfall in number of Neurocrine Researcher FTEs devoted to the Research Program versus the funded number of Neurocrine Researcher FTEs set forth in Section 5.5, it is determined at the end of the term of the Research Program that Neurocrine has, over the life of the Research Program, utilized less than the number of Neurocrine Researcher FTEs funded by Wyeth-Ayerst hereunder, Neurocrine shall within thirty (30) days after such determination refund to Wyeth-Ayerst the excess Research Program funding provided to Neurocrine under Section 5.5(a) above, which refund shall be equal to [***] multiplied by the difference between (x) the number (in the aggregate) of Neurocrine Researcher FTEs that were funded by Wyeth-Ayerst [***] Research Program in accordance with Section 5.5 and (y) the actual number of Neurocrine Researcher FTEs, in the aggregate, that were devoted to the Research Program [***] Research Program. For example, if the number of Neurocrine Researcher FTEs funded by Wyeth-Ayerst [***] of the Research Program was [***] and Neurocrine, in fact, only utilized [***] Neurocrine Researcher FTEs [***] of the Research Program, Neurocrine would refund [***] to Wyeth-Ayerst.

Wyeth-Ayerst will pay to Neurocrine, Royalties, on a Collaboration Product by Collaboration Product basis, which Royalties shall be calculated using the following formula: [***] where, A equals [***] of Wyeth-Ayerst's worldwide Net Sales of such Collaboration Product, which, during the calendar year in question, are [***] B equals [***] of Wyeth-Ayerst's worldwide Net Sales of such Collaboration Product, which, during the calendar year in question, [***]; and C equals [***] of Wyeth-Ayerst's worldwide Net Sales of such Collaboration Product, which, during the calendar year in question, are [***]. By way of example only, if, during a given year, Wyeth-Ayerst, its Affiliates and sublicensees [***] the royalty payable by Wyeth-Ayerst to Neurocrine during such year would be calculated as follows: [***] Neurocrine acknowledges and agrees that nothing in this Agreement shall be construed as representing an estimate or projection of either (i) the number of Collaboration Products that will or may be successfully developed and/or commercialized estimate or (ii) anticipated sales or the actual value of the Neurocrine Technology, any Lead Compound or any Collaboration Product and that the figures set forth in this Section 9.1 or elsewhere in this Agreement or that have otherwise been discussed by the Parties are merely intended to define Wyeth-Ayerst's royalty obligations to Neurocrine in the event such sales performance is achieved. WYETH-AYERST MAKES NO REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, THAT IT WILL BE ABLE TO SUCCESSFULLY DEVELOP AND/OR COMMERCIALIZE ANY COLLABORATION PRODUCTS OR, IF COMMERCIALIZED, THAT IT WILL ACHIEVE ANY PARTICULAR SALES LEVEL OF SUCH COLLABORATION PRODUCT(S). 9.2 Royalty Adjustments. Royalties on a Collaboration Product are subject to reductions and adjustments as a result of certain events as set forth below; provided, however, in no event will Royalties on a Collaboration Product in any country be [***] by reason of the adjustments set forth below. (a) Royalty Adjustment for Unpatented Products. If, during a given calendar quarter, a Collaboration Product is an Unpatented Product in one or more countries, the Royalties will be payable to Neurocrine for the Net Sales of such Collaboration Product in such country(ies) during such calendar quarter at [***] of the royalty rate(s) set forth in Section 9.1 above. To calculate the Unpatented Product Royalties, [***]. The fact that a Collaboration Product is an Unpatented Product in one country during any calendar quarter shall not result in a reduction of the royalty rate used to calculate the Royalty payable for sales of Collaboration Products in any other country during such calendar quarter. (b) Competition. If Competition exists, during a given calendar quarter with respect to a Collaboration Product in a country, the royalty rate(s) used to calculate the Royalties payable to Neurocrine for the sale of such Collaboration Product in such country during such calendar quarter will [***] of the royalty rate(s) set forth in Section 9.1 above. To calculate the Royalties when Competition exists in one or more countries, [***]. The existence of Competition in one country during any calendar quarter shall not result in a reduction of the royalty rate used to calculate the Royalty payable for sales of Collaboration Products in any other country during such calendar quarter. If at the time of determining any Competition adjustments, applicable IMS International data (or such other data as may be mutually agreed by the Parties) for such time period is unavailable, Wyeth-Ayerst may make a reasonable estimate thereof based on prior available IMS International data (or such other data as may be mutually agreed by the Parties) and calculate the applicable Royalty based on such estimate, and any difference in Royalty payments made by Wyeth-Ayerst based on such estimate and Royalty payments based on actual data, once available, will be accounted for by an adjustment payment by Wyeth-Ayerst at the time the next quarter Royalty payment is made or an adjustment credit against Wyeth-Ayerst's future Royalty obligations, as the case may be. 9.3 Term of Royalty. Royalties will be payable on a country by country and Collaboration Product by Collaboration Product basis until the later of (i) the last to expire, in such country, of the Patent Rights included within the Collaboration Technology, [***] or (ii) with respect to the sale of such Collaboration Product in countries of the European Union, [***] from First Commercial Sale of such Collaboration Product in the European Union and, with respect to the sale of such Collaboration Product in any country outside of the European Union, [***] from First Commercial Sale of such Collaboration Product in such country. Upon the expiration of Wyeth-Ayerst's obligation to pay Royalties to Neurocrine hereunder with respect to a Collaboration Product, Wyeth-Ayerst shall have a fully paid, irrevocable, exclusive and unrestricted license under the Collaboration Technology to make, have made, use, sell, offer to sell and import such Collaboration Product. 9.4 Reports and Payments. (a) Cumulative Royalties. The obligation to pay Royalties under this Article Nine shall be imposed only once (i) with respect to any sale of the same unit of Collaboration Product and (ii) with respect to a single unit of Collaboration Product regardless of how many Valid Claims of Patent Rights included in the Collaboration Technology would, but for this Agreement, be infringed by the making, using or selling of such Collaboration Product. (b) Statements and Payments. Wyeth-Ayerst shall deliver to Neurocrine within sixty (60) days after the end of each calendar quarter, a report certified by Wyeth-Ayerst as accurate to the best of its ability based on information then available to Wyeth-Ayerst, setting forth for such calendar quarter the following information on a country-by-country and Collaboration Product by Collaboration Product basis: (i) Net Sales of such Collaboration Product in such country, (ii) the basis for any adjustments to the Royalty payable for the sale of such Collaboration Product in such country and (iii) the Royalty due hereunder for the sale of such Collaboration Product in such country. The total Royalty due for the sale of Collaboration Products during such calendar quarter shall be remitted at the time such report is made. (c) Taxes and Withholding. All payments under this Agreement will be made without any deduction or withholding for or on account of any tax unless such deduction or withholding is required by applicable law or regulations. If the paying Party is so required to deduct or withhold such Party will (i) promptly notify the other Party of such requirement, (ii) pay to the relevant authorities the full amount required to be deducted or withheld promptly upon the earlier of determining that such deduction or withholding is required or receiving notice that such amount has been assessed against the other Party, (iii) promptly forward to the other Party an official receipt (or certified copy) or other documentation reasonably acceptable to the other Party evidencing such payment to the authorities. In case the other Party can not take a full credit against its tax liability for the withholding tax deducted or withheld by the paying Party, then such other Party may propose a change to the then current arrangement with respect to the flow of moneys under this Agreement in order to reduce or eliminate the extra cost for any Party and the Parties, with no obligation as to outcome, shall discuss such proposal in good faith. (d) Currency. All amounts payable and calculations hereunder shall be in United States dollars. As applicable, Net Sales shall be translated into United States dollars in accordance with Wyeth-Ayerst's customary and usual translation procedures, consistently applied. (e) Maintenance of Records; Audit. For a period of three (3) years, Wyeth-Ayerst shall maintain and shall cause its Affiliates and sublicensees to maintain complete and accurate books and records in connection with the sale of Collaboration Products hereunder, as necessary to allow the accurate calculation of Royalties due hereunder including any records required to calculate any Royalty adjustments hereunder. Once per calendar year Neurocrine shall have the right to engage an independent accounting firm acceptable to Wyeth-Ayerst, at Neurocrine's expense, which shall have the right to examine in confidence the relevant Wyeth-Ayerst records as may be reasonably necessary to determine and/or verify the amount of Royalty payments due hereunder. Such examination shall be conducted during Wyeth-Ayerst's normal business hours, after at least fifteen (15) days prior written notice to Wyeth-Ayerst and shall take place at the Wyeth-Ayerst facility(ies) where such records are maintained. Each such examination shall be limited to pertinent books and records for any year ending not more than thirty-six (36) months prior to the date of request. Before permitting such independent accounting firm to have access to such books and records, Wyeth-Ayerst may require such independent accounting firm and its personnel involved in such audit, to sign a confidentiality agreement (in form and substance reasonably acceptable to Wyeth-Ayerst) as to any of Wyeth-Ayerst's, its Affiliates or sublicensees' confidential information which is to be provided to such accounting firm or to which such accounting firm will have access, while conducting the audit under this Section 9.5 (e). The Neurocrine independent accounting firm will prepare and provide to both Neurocrine and Wyeth-Ayerst a written report disclosing only whether the Royalty reports submitted and Royalties paid by Wyeth-Ayerst are correct or incorrect and the specific details concerning any discrepancies. No other information shall be provided to Neurocrine. In the event there was an under-payment by Wyeth-Ayerst hereunder, Wyeth-Ayerst shall promptly (but in no event later than thirty (30) days after Wyeth-Ayerst's receipt of the independent auditor's report so correctly concluding) make payment to Neurocrine of any short-fall. In the event that there was an over-payment by Wyeth-Ayerst hereunder, Neurocrine shall promptly (but in no event later than thirty (30) days after Neurocrine's receipt of the independent auditor's report so correctly concluding) refund to Wyeth-Ayerst the excess amount. In the event any payment by Wyeth-Ayerst shall prove to have been incorrect by more than seven and one-half percent (7.5%) to Neurocrine's detriment, Wyeth-Ayerst will pay the reasonable fees and costs of Neurocrine's independent auditor for conducting such audit. 9.5 Third Party Payments. (a) OHSU Agreement. The Parties have agreed to share equally the royalty payments to OHSU required under paragraph 6.02 of the OHSU Agreement (the "Shared Obligation"). All other payments under the OHSU Agreement shall be the responsibility of Neurocrine. Neurocrine shall be responsible for making all payments due under the OHSU License Agreement and, within ten (10) days of making any payment required under paragraph 6.02 of the OHSU Agreement, Neurocrine shall provide to Wyeth-Ayerst documentary evidence that such payment has been made. Within thirty (30) days after Wyeth-Ayerst receives from Neurocrine such documentary evidence, Wyeth-Ayerst shall pay to Neurocrine an amount equal to [***] of the payments due to the Oregon Health Sciences University pursuant to [***] for Licensed Patent Rights (as defined in the OHSU Agreement) included in the Neurocrine Technology licensed to Wyeth-Ayerst hereunder, provided, however, that any credits that may accrue to Neurocrine by reason of payments by Neurocrine to OHSU pursuant to [***] will be considered a credit against Neurocrine's portion of Shared Obligation, and any credits that may accrue pursuant to [***] or Wyeth-Ayerst, as the case may be, will be considered a credit against Neurocrine's or Wyeth-Ayerst's, respectively, portion of the Shared Obligation. (b) Neurocrine Technology. [***] from any Third Party owning or Controlling Patent Rights which would be infringed by [***] under this Agreement, a license under such Patent Rights, which license would permit [***] will be solely responsible for paying [***] of the license fees and royalties that may be payable to any such Third Party for such license(s). In the event [***] fails or in unable to negotiate an agreement with such Third Party within [***] may negotiate such license on terms reasonably agreed to by [***] and in the event [***] in obtaining such license on terms agreed to by [***] in its good faith business judgment [***] amounts payable thereunder. If [***] is unable to agree as to whether it is necessary to obtain such a license from a Third Party, the issue shall be referred to [***]. (c) Collaboration Products. Except as set forth in (a) and (b) above, [***] determining whether to negotiate an agreement with any Third Party that owns or Controls a Patent Right claiming the manufacture or use of any Collaboration Product.

The Parties recognize that the designation of a Compound as a Lead Compound or Collaboration Product may impact the designation of the Party responsible for such invention under this Article Thirteen. The Parties anticipate that patent applications may be filed on Compounds prior to designation of the Compound as Lead Compound or Collaboration Product, and agree to co-operate in deciding how to allocate responsibilities and expenses in the event designation of a Compound as a Lead Compound or Collaboration Product impacts responsibilities under this Article Thirteen. In addition, the Parties agree to cooperate with each other in the preparation, filing, prosecuting, maintenance, defense and enforcement of Patent Rights included in Collaboration Technology licensed hereunder. In any action taken in the prosecution of, or in the defense of an action by a Third Party related to patent invalidity or non-patentability of any patent application or patent claiming Collaboration Technology licensed hereunder, neither Party shall admit the invalidity or non-patentability of any Patent Right or take any other action that may diminish Patent Rights within Collaboration Technology licensed hereunder without the other Party's prior written consent. Wyeth-Ayerst agrees to provide Neurocrine with sufficient time to review, comment and consult on all patent applications and patents and all correspondence to and from the various patent offices, including, but not limited to, proposed responses, interferences and oppositions, claiming Neurocrine Inventions, Joint Inventions and Wyeth-Ayerst Inventions. The Parties agree to cooperate with each other and to use best efforts to ensure the cooperation of any of their respective personnel and licensee(s) or licensor(s) as might reasonably be requested in any such matters, and shall sign any necessary legal papers and provide the prosecuting party with data or other information in support thereof. The Parties will confer on what action to take with respect to the defense of infringement proceedings naming both Wyeth-Ayerst and Neurocrine or in proceedings to enforce patents claiming Collaboration Technology licensed hereunder against a Third Party. If the Parties cannot agree on the course of action to be taken in the filing, prosecution, maintenance, or enforcement of any Joint Invention or Wyeth-Ayerst Invention, Wyeth-Ayerst's decisions shall control. If the Parties cannot agree on the course of action to be taken in the filing, prosecution, maintenance, or enforcement of Neurocrine Invention, Neurocrine's decisions shall control.
