Either Tanabe or OSI, as the case may be, shall use commercially reasonable and diligent efforts to exploit the Products. This requirement shall be deemed satisfied if such party uses substantially the same degree of diligence it uses with respect to products of similar commercial potential developed by such party outside of this Agreement. 5.4 Sublicenses. If either Tanabe or OSI grants a sublicense pursuant to Section 5, such party shall guarantee that any sublicensee fulfills all of its obligations under this Agreement. In the event Tanabe or OSI grants sublicenses under Section 5 to others to develop, have developed, make, have made, use, sell or have sold Products, such sublicenses shall include an obligation of the sublicensees to account for and report all Net Sales of Products on the same basis as if such sales were Net Sales of Products by such party, and such party shall pay royalties to the other party under this Agreement as if the Net Sales of the sublicensee were Net Sales of the sublicensor. 5.5 Royalty Payments, Accounting for Royalties, Records and Withholding Tax. 5.5.1 Royalty Payments by Tanabe. Tanabe shall pay to OSI a royalty of (a) ** of the Net Sales made by Tanabe, its Affiliates and sublicensees of each Tanabe Product, and (b) ** of the Net Sales made by Tanabe, its Affiliates and sublicensees of each OSI Product. Tanabe shall continue to pay royalties on Net Sales of each Product on a country- - ------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 38 47 by-country basis so long as the manufacture, use and/or sale of such Product would infringe a Valid Claim of an OSI Patent or a Joint Patent with respect to such Product in such country or for ** following the date of first commercial sale of such Product, whichever is longer. Upon the request of OSI, Tanabe will, at its option, identify OSI on the packaging of all Products on which Tanabe is obligated to pay royalties, subject to legal and commercial requirements on a country-by-country basis and in a manner in accordance with such legal and commercial requirements. 5.5.2 Royalty Payments by OSI. In the event that the exclusive option or the exclusive license, as the case may be, with respect to a Lead Compound revert to OSI and OSI is granted the license set forth in Section 5.1.2 hereof, OSI shall pay to Tanabe a royalty of ** of Net Sales by OSI, its Affiliates or sublicensees of each such Product. OSI shall continue to pay such royalty on Net Sales of each Product commercialized by OSI, its Affiliates or sublicensees on a country-by-country basis so long as the manufacture, use and/or sale of such Product would infringe a Valid Claim of a Tanabe Patent or a Joint Patent with respect to such Product in such country or for ** following the date of first commercial sale of such Product, whichever is longer. 5.5.3 Payment Dates. Royalties shall be paid by Tanabe or OSI, as the case may be, on Net Sales within 90 days after the end of each calendar quarter in which such Net Sales are made. Such payments shall be accompanied by a statement showing the Net Sales of each Product in each country and a calculation of the amount of royalty due. 5.5.4 Accounting. The Net Sales used for computing the royalties payable to OSI by Tanabe, or to Tanabe by OSI, as the case may be, shall be computed and - ------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 39 48 paid in U.S. Dollars. For purposes of determining the amount of royalties due with respect to Net Sales in any foreign currency, the amount shall be computed generally by converting the foreign currency amount into U.S. Dollars using for each quarter's calculation the foreign currency exchange rate on the last day of such quarter or such other method as is consistent with internal foreign currency translation procedures of the Selling Party, as actually used by the Selling Party on a consistent basis in preparing its audited financial statements. 5.5.5 Records. Tanabe or OSI, as the case may be, shall keep for seven years from the date of each payment of royalties complete and accurate records of Net Sales made by such party, its Affiliates and sublicensees of each Product in sufficient detail to allow the accruing royalties to be determined accurately. The Royalty-Receiving Party shall have the right for a period of seven years after receiving any report or statement with respect to royalties due and payable to obtain, at its expense, from the independent certified public accountant selected by the Royalty-Receiving Party, an audit of the relevant records of the Selling Party to verify such report or statement. The Selling Party shall make its records available for inspection by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from the Royalty-Receiving Party, to the extent reasonably necessary to verify the accuracy of the reports and payments. Such inspection right shall not be exercised more than once in any calendar year nor more than once with respect to sales in any given period, unless a subsequent inspection reveals discrepancies which may have also occurred during such period. Such independent certified public accountant shall report to the Royalty-Receiving Party only as to the accuracy of the Net Sales computation and royalty payments. The Royalty-Receiving Party agrees to hold in strict confidence all information concerning royalty payments and reports, and all information learned in the course of any audit or inspection, except to the extent necessary for such party to reveal 40 49 such information in order to enforce its rights under this Agreement or disclosure is required by law or by the competent authorities. The failure of the Royalty-Receiving Party to request verification of any report or statement during the seven-year period shall be considered acceptance of the accuracy of such report, and the Selling Party shall have no obligation to maintain records pertaining to such report or statement beyond the seven-year period. The results of the inspection shall be binding on both parties. 5.5.6 Withholding Taxes. (a) ** (b) Withholding to be Borne by Royalty-Receiving Party. Any Withholding Tax imposed on any amounts under Section 5.5 hereof shall be deducted from the amount otherwise due. The Selling Party will assist the Royalty-Receiving Party in minimizing the Withholding Tax applicable to any payment made by the Selling Party hereunder and in claiming tax refunds at the Royalty-Receiving Party's request by providing such documents and providing such other reasonable cooperation as may be necessary to assist the Royalty-Receiving Party in receiving a tax refund or in claiming a foreign tax credit and shall, upon the Royalty-Receiving Party's request, give proper evidence from time to time as to the payment of such Withholding Tax. - ------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 41 50 5.6 Payment to Vanderbilt.

When information comes to the attention of either Tanabe or OSI to the effect that a Tanabe Patent, OSI Patent or Joint Patent or Improvement relating to a Compound or Product have been or are threatened to be unlawfully disclosed or that any of the rights granted by this Agreement have been or are threatened to be unlawfully infringed, such party shall notify the other party in writing and the Selling Party shall have the right at its expense to take such action as it may deem necessary to prosecute or prevent such unlawful disclosure or infringement, including the right to bring or defend any suit, action or proceeding involving any such disclosure or infringement. The Selling Party shall notify the Royalty-Receiving Party promptly of the receipt of any such information and of the commencement of any such suit, action or proceeding. If the Selling Party determines that it is necessary or desirable for the Royalty-Receiving Party to join any such suit, action, or proceeding, the Royalty-Receiving Party shall execute all papers and perform such other acts as may be reasonably required to permit the Selling Party to act in the Royalty-Receiving Party's name. If Tanabe is the Selling Party, and Tanabe determines that it is necessary or desirable for Vanderbilt to join any such suit, action, or proceeding, OSI shall undertake to have Vanderbilt execute all papers and perform such 43 52 other acts as may be reasonably required to permit Tanabe to act in Vanderbilt's name but at no cost to OSI or Vanderbilt ** .

The Selling Party shall have the right (including the right to exclusive control of the defense of any such suit, action, or proceeding and the exclusive right to compromise, litigate, settle, or otherwise dispose of any such suit, action, or proceeding), but not the obligation, to control the defense or settlement of any such suit, action, or proceeding and the Royalty-Receiving Party shall furnish to the Selling Party all necessary information and assistance in connection therewith. The Selling Party shall bear ** of the expense (including, without limitation, any sums paid to such Third Party as damages), and the Royalty-Receiving Party shall bear ** of the expense (including, without limitation, any sums paid to such Third Party as damages); provided that the sole obligation of the Royalty-Receiving Party will be paid by a ** reduction of all royalties then payable and payable thereafter to the Royalty-Receiving Party until the Royalty Receiving Party's ** share of the expenses of such suit are deducted on a global basis, and not on a patent-by-patent basis nor country-by-country basis. If such suit results in any award or settlement paid in favor of Tanabe or OSI, such amount shall be shared in the same proportion as the expenses of such suit have been actually borne by such parties. The share of the expenses of any suit of the Royalty-Receiving Party shall be limited to the foregoing royalty reduction and ** . It is agreed that if one party conducts the defense, the other shall have the right to be represented - ------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 45 54 by advisory counsel of its own selection, at its own expense, and shall cooperate fully in the defense of such suit and furnish to the other all evidence and assistance in its control. 6.3.3 Third Party Licenses. If Tanabe and OSI agree that the development, manufacture, use, or sale by Tanabe or OSI, as the case may be, of a Product in any country would infringe a patent owned by a Third Party, the Selling Party shall attempt to obtain a license under such patent. If the Selling Party obtains a license under such patent, ** of any payments made by the Selling Party to such Third Party shall be deductible from royalty payments due from the Selling Party to the Royalty-Receiving Party; provided, however, that in no event shall royalties payable to the Royalty-Receiving Party be reduced by more than ** as a result of all such deductions. All such computations, payments, and adjustments of ** shall be made on a country-by-country and patent-by-patent basis. If either Tanabe or OSI is of the opinion that such development, manufacture, use, or sale would not infringe such patent owned by a Third Party, the Selling Party may, at its election and expense, bring suit against such Third Party seeking a declaration that such Third Party patent is invalid or not infringed by such party's development, manufacture, use or sale of such Product, or may bring opposition, nullity, or other proceedings against such patent, as appropriate. If the Selling Party chooses not to bring such a suit or is successful in such suit, the Selling Party shall continue to pay royalties in such country as provided in Section 5. If the Selling Party is unsuccessful in such suit, it shall join the Royalty-Receiving Party in an attempt to obtain a license under such patent to the extent that the terms and conditions to obtain such license from - ------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 46 55 such Third Party are commercially feasible, and royalty payments made to such Third Party for such license shall be as provided in this Section. 6.3.4 No Selling Party. For purposes of this Section 6.3, if there is no Selling Party (because no license has yet been granted under Section 5.1.1 or Section 5.1.2), all references to "Selling Party" shall be deemed to be references to OSI and all references to "Royalty-Receiving Party" shall be deemed to be references to Tanabe except that if the actual or threatened unlawful disclosure or infringement solely relates to a Tanabe Patent, then all references in this Section 6.3 to "Selling Party" shall be deemed to be references to Tanabe and all references to "Royalty-Receiving Party" shall be deemed to be references to OSI. 6.3.5 Acquisition of Rights from Third Parties. Subject to OSI's rights with respect to potential pharmaceutical products in the Field licensed-in by OSI during the Contract Period as set forth in Section 2.3.1 hereof, OSI and Tanabe shall, during the Contract Period, promptly notify the Joint Management Committee in writing of any and all opportunities to acquire in any manner from Third Parties (except Vanderbilt under the Vanderbilt Agreement) enabling technologies or patents relating to the Targets which may be used in the Research Program and which were not theretofore available to the Research Program from either Tanabe or OSI. Such opportunities shall include, without limitation, a research collaboration with a Third Party which relates to any of the Targets. If OSI and Tanabe mutually determine that such rights should be acquired or a research collaboration with a Third Party should be entered into, the notifying party shall negotiate with such Third Party to make the acquisition or enter into the research collaboration. If such rights are acquired or a research collaboration is entered into, such rights acquired or resulting from such research collaboration shall be deemed part of the Technology of the party making the acquisition or entering into the research collaboration. Upon 47 56 such acquisition or entering into the research collaboration, OSI and Tanabe shall negotiate in good faith the modification (if any) of the milestone and royalty payments set forth in Sections 3.3.2, 3.3.3 and 5.5 with respect to Products directly resulting from such acquired technology or patents or from such research collaboration. 7.
