ARTICLE III -- ROYALTIES, ETC. 3.1 Royalties to CPEC on Net Sales. In consideration of the exclusive rights granted by CPEC hereunder, Intercardia shall pay CPEC a royalty equal to 6.5% of Net Sales of the Product in the Knoll Territory. CPEC shall be entitled to the foregoing royalty on Net Sales of the Once-a-Day Formulation of Bucindolol, whether or not CPEC shares in the cost of developing the Improvement under Section 8.9 of the LLC Agreement. The royalty shall be payable by Intercardia on Net Sales of the Product in the Knoll Territory, whether sold directly by Intercardia, Knoll (or an affiliate thereof) or any other permitted sublicensee of Intercardia. 3.2 Duration of Royalty Obligation. Intercardia's obligation to pay CPEC royalties under Section 3.1 of this Agreement shall continue for fifteen years from the first commercial sale of the Product in the Knoll Territory, or termination or expiration of the Knoll Agreement in accordance with its terms, whichever is longer. 3.3 Milestone Payments under Knoll Agreement. Intercardia will pay CPEC 65% of the $10 million milestone payment received under Section 3.4(d) of the Knoll Agreement (i.e., if Net Sales of the Product in the Knoll Territory exceed $200 million in any consecutive twelve-month period). Intercardia shall notify CPEC in writing 10 days after the receipt of payment of this milestone and such notice shall be accompanied by payment. Intercardia will be entitled to retain the entire $10 million milestone payment due under Section 3.4(c) of the Knoll Agreement upon the first regulatory approval of the Product in certain countries of the European Community. 3.4 Currency. The payments to CPEC under 3.1 and 3.3 shall be paid in U.S. dollars, converted from foreign currency in the same manner as Knoll converts royalties from foreign currency into U.S. dollars under the Knoll Agreement. 3.5 Place of Payment. All payments to CPEC under this Agreement shall be made by check or wire transfer in immediately available funds in legal currency of the United States and shall be delivered to CPEC at the address or account designated in writing by CPEC from time to time. 3.6 Timing of Payment and Royalty Reports. Royalties shall be paid by Intercardia to CPEC within 40 days after the end of each calendar quarter. The payment shall be accompanied by a report of Intercardia, setting forth in reasonable detail the calculation of the royalties payable to CPEC for such calendar quarter, including the Net Sales of the Product and the currency conversion calculation. In addition, Intercardia will furnish CPEC within 24 hours after receipt by Intercardia with copies of any written reports provided by Knoll that relate to the amount or calculation of Net Sales in the Knoll Territory. 3.7 Defaults in Payment Obligations; Interest. If Intercardia defaults in its payment obligations to CPEC with respect to Net Sales of the Product in the Knoll Territory or the milestone payment to be shared with CPEC, interest shall accrue on the defaulted amount at the rate of 20% per annum until the defaulted payment, with accrued interest, is paid. The amount of the defaulted payment and accrued interest shall be treated as "Member Debt" under Section 8.7 of the LLC Agreement. If such default does not stem from a payment default by Knoll to Intercardia, Intercardia, at CPEC's request, shall assign to CPEC the right to receive a portion of the royalty or any other payment due under Section 3.4 of the Knoll Agreement, if any, owed by Knoll to Intercardia sufficient to satisfy such default. If Knoll has defaulted on its payment obligation, Intercardia, at CPEC's request, will use all commercially reasonable efforts to exercise its rights and remedies under the Knoll Agreement, and will keep CPEC informed of all such efforts. The foregoing shall be in addition to any other rights and remedies CPEC may have under this Agreement or otherwise, at law or in equity, for such default. 3.8 Third Party Royalties. Intercardia shall be responsible for the timely payment of any royalties payable to BMS under the BMS License upon Net Sales of the Product in the Knoll Territory. Intercardia shall be responsible for any other royalties or similar payments owed to third parties as a result of Intercardia's commercialization of Product in the Knoll Territory under this Agreement. 3.9 Repatriation Restrictions. Intercardia shall exercise reasonable due diligence to determine if restrictions on the transfer of currency exist in any country which would prevent Intercardia from making payments in the United States. If an unexpected currency restriction occurs, Intercardia shall take all reasonable steps to obtain a waiver of such restrictions or to otherwise enable Intercardia to make such payments, failing which, if Intercardia is prevented from making any payment under this Agreement by virtue of restrictions on currency conversion or repatriation under the statutes, laws, codes or governmental regulations of the country from which the sales are generated or the payment is to be made, then such payments may be paid by depositing them in the local currency to CPEC's account in a bank acceptable to CPEC in the country whose currency is involved. 3.10 Taxes. If laws, rules or regulations require withholding of income taxes or other taxes imposed upon payments payable by Intercardia to CPEC as set forth in this Article 3, Intercardia shall make such withholding payments as required and subtract such withholding payments from the payments set forth in this Article 3. Intercardia shall submit appropriate proof of payment of the withholding taxes to CPEC within a reasonable period of time. Intercardia will use efforts consistent with its usual business practices to minimize foreign withholding taxes and CPEC shall cooperate with such efforts. Intercardia will be responsible for any other taxes and assessments on sales of the Product and its other activities under this Agreement. 3.11 Records. Intercardia will maintain for three (3) years after the submission of each report under Section 3.5 hereof complete and accurate books and records in sufficient detail to enable the milestone payment and the royalties payable hereunder to be verified. Upon reasonable prior notice to Intercardia, CPEC or its duly authorized representative, at CPEC's cost and expense, shall have access to and the right to copy the books and records of Intercardia to conduct an inspection, examination, review or verification thereof. Such access shall be available not more than twice each calendar year, during normal business hours, during the term of this Agreement and for a period of three (3) years after its expiration or termination.

Each party may have access through CPEC (including as a member, director or member of the BEXTRA Committee) or otherwise under this Agreement to confidential or proprietary information of CPEC or third parties (including Knoll). In such event, the receiving party shall hold in confidence and not disclose to any third party any information from the disclosing party that is marked as confidential or proprietary, and shall cause its representatives to do the same. This restriction shall not apply to information that becomes part of the public domain through no fault of the receiving party or is obtained from a third party who is not under any obligation of confidentiality. In addition, Intercardia may disclose such information to Knoll for purposes of the Knoll Agreement, and any receiving party may disclose the information to a consultant, collaborator or potential collaborator who is subject to obligations of confidentiality comparable to those set forth in this Section 9.4, if necessary in connection with the conduct of its responsibilities under this Agreement. If the receiving party receives a subpoena or becomes subject to any other legal process requiring disclosure of the disclosing party's confidential or proprietary information, it will promptly notify the disclosing party and cooperate to minimize the scope of the disclosure to the extent practicable.
