If Kyowa Hakko has not exercised the Option prior to such termination, then the Option will terminate as provided in Paragraph 3.1(c)(iii), Kyowa Hakko will have no further obligation to supply, or fund the purchase of, bulk [*] for use in the Joint Territory, and COR shall have no royalty obligation to Kyowa Hakko with respect to the Joint Territory. (c) Royalties payable by COR pursuant to Paragraph 2.4(b) above shall terminate as to each [*] Product and as to each country in the Joint Territory upon the later to occur of (i) the last to expire of a patent for a [*] Product in such country or (ii) [*] after the first commercial sale of such [*] Product in such country. Such royalties shall be paid quarterly within 60 days after the end of each calendar quarter. Such royalties shall be calculated on the basis of Net Sales of [*] Products in the local currency of each country, and converted into U.S. Dollars and paid in U.S. Dollars on the basis of the currency exchange rate published in the Wall Street Journal or comparable newspaper of international circulation on the last business day of the quarter in which such sales were made. In the event of Net Sales of [*] Products being made in a currency as to which conversion into U.S. Dollars is then blocked, COR shall make payment to Kyowa Hakko in such local currency in a bank account designated by Kyowa Hakko. COR shall withhold any taxes on such royalties required by law. Each royalty payment shall be accompanied by a statement of such royalties showing the Net Sales of each [*] Product during such quarter, the calculation of the royalties due, and showing evidence of payment as to any taxes paid on Kyowa Hakko's behalf. Any refunds or rebates of taxes paid to COR on behalf of Kyowa Hakko shall be remitted promptly by COR to Kyowa Hakko. COR shall use reasonable diligence in the development and marketing of [*] Products which are royalty-bearing under Paragraph 2.4(b). (d) If COR terminates its funding of Development Costs in the Joint Territory at any time as provided in this Paragraph 2.4, then its rights to develop and commercialize [*] Products in the Joint Territory shall terminate and Kyowa Hakko shall pay a royalty to COR equal to [*] of the Net Sales of such [*] Product in the Joint Territory. The provisions of Paragraph 2.4(c) shall apply equally to the payment of royalties under this Paragraph 2.4(d). 2.5 NON-CARDIOVASCULAR INDICATIONS. The initial clinical studies of [*] Products will be for use in cardiovascular indications. However, the parties expect also to explore the use of [*] Products for other indications, the first of which are likely to be [*] indications.

If the parties agree that development or commercialization of a [*] which is based upon the [*], including any [*] of such [*], is not feasible or practical, and the parties desire to proceed with development of an available alternative [*] and to which either COR or Kyowa Hakko then holds rights, they may add such [*] to the definition of [*] by mutual agreement. 3.

(i) Defense and Settlement of Third Party Claims for Collaboration Products and [*] Products in the Joint Territory. If a Third Party asserts that a patent or other right owned by it is infringed by the manufacture, use or sale of any Product or any [*] Product in the Joint Territory (so long as both parties retain option or license rights to co- promote such product in the Joint Territory), the Party first obtaining knowledge of such a claim shall immediately provide the other Party notice of such claim and the related facts in reasonable detail. In such event, the Steering Committee shall determine how best to control the defense of any such claim. In the event the Parties cannot agree on the defense of any such claim, COR shall have the right, but not the obligation, to control such defense. Kyowa Hakko shall cooperate with COR and shall have the right to be represented separately by counsel of its own choice. The entity (whether Steering Committee or COR) that controls the defense of a given claim, shall also have the right to control settlement of such claim; provided, however, that if one Party controls, no settlement shall be entered into without the written consent of the other Party if such settlement would adversely affect the interests of such other Party. (ii) Allocation of Expense. The expenses of patent defense, settlement and judgments pursuant to Section 11.10(i) shall be a shared expense of the Parties. Such costs which are incurred after the designation of the Product or [*] Product for development but prior to Regulatory Approval shall be borne in the same manner as if such costs were Development Costs. Such costs which are incurred following Regulatory Approval shall be an Allowable Expense, reimbursed to the Party incurring such expense. (iii) Settlement of Third Party Claims for Cancer Products in all territories and Products and [*] Products in the U.S. and the Asian Territory; Royalty Reduction. If a Third Party asserts that a patent or other right owned by it is infringed by any [*], or any Product or [*] Product in the U.S. or the Asian Territory (or the Joint Territory if only one Party retains marketing rights for such product in the Joint Territory), the Party with rights to market such product in such territory shall control the defense of such action and bear any litigation costs, settlement costs, royalties or other costs or payments due to the Third Party which may be incurred by either Party arising out of such action. * 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 24-b2 of the Securities Exchange Act of 1934, as amended.
