Article 5

Designation of Lead Compounds and Marketing Rights

5.1 Designation of Lead Compound. From time to time, Warner may formally designate one or more Collaboration Compounds for further development, and such designated compounds shall be deemed Collaboration Lead Compounds. Such designation shall be made under Warner’s then current standards for declaring one of its own compounds a “lead compound.” Such designation generally indicates that Warner has identified such compound as a candidate for cGLP/cGMP studies. Warner will pursue the research and development of each Collaboration Lead Compound at its own expense and under its sole direction. Warner will provide Onyx quarterly, written updates regarding the status of each Collaboration Lead Compound.

11.

5.2 Collaboration Product. Each Collaboration Lead Compound shall be referred to herein as a “Collaboration Product” from and after filing of an IND in respect of such compound with the FDA or the filing of its equivalent in any foreign country other than Japan. The preparation, filing and prosecution of IND’s, NDA’s and other regulatory filings required to be filed with the FDA and its foreign equivalents (other than in Japan) in regard to any Collaboration Product will be at the sole expense of, in the name of and under the direction of Warner. Warner does not warrant that any regulatory filings will actually be filed or, if filed, will be approved.

5.3 Independent Development. From time to time, Onyx may request Warner in writing to undertake specific research and development regarding a Collaboration Compound or to declare a Collaboration Compound to be a Collaboration Lead Compound. Warner will notify Onyx within [*] of receiving Onyx’s written request if it determines before such date that it will not undertake such specific research and development (or declare such Collaboration Compound to be a Collaboration Lead Compound) within [*] of such request (“Warner’s Notice to Decline”). If Warner does not so notify Onyx within such [*] period, it will periodically review Onyx’s request and if it determines not to undertake such specific research and development (or declare such Collaboration Compound to be a Collaboration Lead Compound) then it shall promptly so notify Onyx (also, “Warner’s Notice to Decline”). After either (i) receipt of Warner’s Notice to Decline, or (ii) if Warner does not so notify Onyx and if Warner does not itself undertake the requested action within [*] of Onyx’s written request, then the date [*] after Warner’s receipt of Onyx’s written request, then Onyx shall undertake continued research and development (including the specific research and development requested by Onyx in its request to Warner) of such Collaboration Compound independently (an “Onyx Lead Compound”), at its sole cost and under its sole direction. Onyx may not utilize the services of the personnel committed to the Collaboration pursuant to Section 2.2 in performance of research or development of an Onyx Lead Compound. Onyx may declare no more than [*] Onyx Lead Compounds during the Term of this Agreement. Onyx will keep Warner currently informed of all material information in its research and development of each Onyx Lead Compound and will allow Warner to comment on the direction of such research and development. Each Onyx Lead Compound is referred to herein as an “Onyx Product” from and after filing of an IND in respect of such compound with the FDA or the filing of its equivalent in any foreign country other than Japan. Onyx will provide Warner a complete and accurate copy of the proposed filing, together with any additional information that Warner may request regarding the relevant Onyx Lead Compound, at least [*] prior to submitting such filing to the FDA or its foreign equivalent.

under the provisions of the following sentence assuming that such Patent did not exist. Subject to the terms of the preceding sentence, if in a particular country there is never an issued Patent that is necessary to sell such Product in such country, then such [*] royalty will be payable, for sales of such Product in such country, until the earliest of (x) the later to occur of (i) the [*] anniversary of such first sale in such country and (ii) expiration of the last Patent necessary to make or use such Product in such country, which Patent was in existence on the date of such first commercial sale, (y) the first calendar quarter in which the sale in such country by any one entity (together with its Affiliates), other than Warner or its Affiliates or licensees, of one or more products containing the same active ingredient as the Product, constitutes [*] or more of all units sold in such country containing such active ingredient and (z) the first calendar quarter in which the sale in such country by any entities (taken in the aggregate), other than Onyx or its Affiliates or licensees, of one or more products containing the same active ingredient as the Product, constitutes [*] or more of all units sold in such country containing such active ingredient (the period from first commercial sale in each country until the earliest of (x), (y) and (z) above is referred to herein as the “Onyx Product Exclusive Period”). In the case of (y) and (z) above, the [*] royalty will terminate as to Net Sales of Product sold on or after the day following the end of the triggering calendar quarter. Onyx will pay Warner [*] of Net Sales as a royalty on sales of Onyx Products in each country (except for Japan) for the [*], respectively, following (a) such final Patent expiration (in the event that the required Patent necessary to sell such Product in such country existed on the date of first commercial sale or issued thereafter) or (b) the end of the Onyx Product Exclusive Period (if no such Patent existed or issued thereafter, and provided that the Onyx Product Exclusive Period lasted at least [*] years); provided, however, that no such royalty will be payable in respect of an Onyx Product sold without the use of one or more trademarks developed by Onyx for such Product during the time that the [*] royalty was applicable.

6.5 Currency of Payment. All payments to be made under this Agreement shall be made in United States dollars in the United States to a bank account designated by the party to be paid. Royalties earned shall first be determined in the currency of the country in which they are earned and then converted to its equivalent in United States currency. Such conversion shall be based on the average buying rates of exchange for the currencies involved into the currency of the United States quoted by Citibank (or its successor in interest) in New York, New York at the close of business on each business day of the quarterly period in which the royalties were earned.

6.6 Payment and Reporting. The royalties due under Section 6.3 or Section 6.5 shall be paid quarterly, within 45 days after the close of each calendar quarter immediately following each quarterly period in which such royalties are earned, or earlier if practical. With each such quarterly payment, the payor shall furnish the payee a royalty statement, setting forth on a country-by-country basis the total number of units and Net Sales of each royalty-bearing Product made, used and/or sold hereunder for the

15.

quarterly period for which the royalties are due. In addition, the payor shall furnish such a royalty statement on a country-by-country basis for the first quarter during which payor makes sales of Product for which no royalty payment in respect of such country is due hereunder, and shall state the basis for such sales then being free of royalty obligations hereunder. The payor shall thereafter have no further obligation to report the number of units or Net Sales of such Product made, used and/or sold in such country.

6.7 Records. The royalty paying party shall keep accurate books and accounts of record in connection with the manufacture, use and/or sale by or for it of the Products hereunder in sufficient detail to permit accurate determination of all figures necessary for verification of royalty obligations set forth in this Article 6. Such records shall be maintained for a period of 3 years from the end of each year in which sales occurred. The payee, at its expense, through a certified public accountant, shall have the right to access such books and records for the sole purpose of verifying the royalty statements; such access shall be conducted after reasonable prior notice by the payee to the payor during the payor’s ordinary business hours and shall not be more frequent than once during each calendar year. Said accountant shall not disclose to the payee or any other party any information except that which should properly be contained in a royalty report required under this Agreement. If such accounting determines that a party’s error resulted in the other party receiving at least 5% less than properly due in respect of any quarter, then the party in error will reimburse such amount and reimburse the other party for the costs of such accounting (including the fees and expenses of the certified public accountant).

6.8 Taxes Withheld. Any income or other tax that one party hereunder, its Affiliates or sublicensees is required to withhold (the “Withholding Party”) and pay on behalf of the other party hereunder (the “Withheld Party”) with respect to the royalties payable under this Agreement shall be deducted from and offset against said royalties prior to remittance to the Withheld Party; provided, however, that in regard to any tax so deducted, the Withholding Party shall give or cause to be given to the Withheld Party such assistance as may reasonably be necessary to enable the Withheld Party to claim exemption therefrom or credit therefor, and in each case shall furnish the Withheld Party proper evidence of the taxes paid on its behalf.

6.9 Computation of Royalties. All sales of Onyx Products between Onyx and any of its Affiliates and sublicensees shall be disregarded for purposes of computing royalties under this Article 6, but in such instances royalties shall be payable only upon sales to unlicensed third parties. Nothing herein contained shall obligate Onyx to pay Warner more than one royalty on any unit of an Onyx Product. All sales of Collaboration Products between Warner and any of its Affiliates and sublicensees shall be disregarded for purposes of computing royalties under this Article 6, but in such instances royalties shall be payable only upon sales to unlicensed third parties. Nothing

16.

herein contained shall obligate Warner to pay Onyx more than one royalty on any unit of a Collaboration Product or a Warner Product.

6.10 Licenses to Affiliates. Each party shall, at the other party’s request, sign license and/or royalty agreements directly with the other party’s Affiliates and sublicensees in those situations where such agreements would not decrease the amount of royalties which would be owed hereunder. Such agreements shall contain the same language as contained herein with appropriate changes in parties and territory. No such license and/or royalty agreement will relieve Warner or Onyx, as the case may be, of its obligations hereunder, and such party will guarantee the obligations of its Affiliate or sublicensee in any such agreement. Royalties received directly from one party’s Affiliates and sublicensees shall be credited towards such party’s royalty obligations under Section 6.3 or 6.5 hereof, as applicable.

6.11 Restrictions on Payment. The obligation to pay royalties under this Agreement shall be waived and excused to the extent that statutes, laws, codes or government regulations in a particular country prevent such royalty payments by the seller of Products; provided, however, that if legally permissible, the seller of Products shall pay the royalties owed to the other party hereto by depositing such amounts in a bank account in such country that has been designated by the party owed such royalties.
