E. The parties hereto wish by the execution, delivery and performance of this Agreement to compromise and settle all differences between and among them.

Within thirty (30) days following the execution and delivery of this Agreement: (a) Braun shall provide to Biopure the information listed in Attachment 1; (b) to the extent that any such information described in Attachment I consists of copies delivered to Braun by Biopure or if Braun has other confidential or proprietary information related to Biopure or its products, Braun shall either return or destroy such copies or information and certify their destruction to Biopure; and (c) in the event that after the execution and delivery of this Agreement Braun discovers in its possession additional materials described in Subparagraphs 2(a) or 2(b) herein, Braun will promptly deliver to Biopure, or destroy, as applicable, such additional materials. Notwithstanding the foregoing, Braun may retain such originals or copies of the foregoing as may be necessary or appropriate but all such information shall be maintained by Braun as confidential information pursuant to the Confidentiality Requirements. 3. Termination of Rights and Duties Under Other Agreements. Braun hereby relinquishes all rights under the Investment Agreement and the Rights Agreement and Braun and Biopure hereby release each other from each of their respective duties and obligations owed to such other party pursuant to the Investment Agreement and Rights Agreement effective upon the execution and delivery of this Agreement.

Royalties. (a) For purposes of this Agreement, the following definitions shall apply: i) European Royalty.

(d) Within thirty (30) days following the end of each calendar quarter, Biopure shall provide to Braun a royalty statement, certified as true and correct by an officer of Biopure, setting forth, with respect to the preceding calendar quarter, the amount of Net Sales, identified by each seller of the Royalty Products and Oxypure, and all license and other fees received by Biopure or its Affiliates upon which the Stock Royalty or the European Royalty is calculated. (e) Biopure shall permit a reputable international firm of public accountants selected by Braun to inspect, examine and audit its books and accounts at such times as Braun may reasonably request (but not more frequently than once each calendar year) for the purpose of verifying Net Sales, the royalty statements and determining the correctness of royalty payments hereunder. The cost of all inspections, examinations and audits shall be borne by Braun, except that the cost of any audit will be borne by Biopure if the audit reveals an -3- <PAGE> 5 underpayment of royalty payments for any period in question of more than five percent (5%) and any additional royalty payments shall be paid with five (5) days of their determination plus interest at ten percent (10%) per annum. 5. Escrow Agreement.

Biopure shall execute any further documents necessary or appropriate to perfect Braun's security interest in such funds. (c) Braun shall be entitled to vote, and shall receive all dividends related to, those Shares being held by the Escrow Agent until their delivery to Biopure. 6. Sale and Purchase of the Shares. Biopure agrees to purchase the Shares pursuant to this Agreement and in compliance with the procedures set forth in the Escrow Agreement and to pay to Braun the sum of six million three hundred thousand dollars ($6,300,000) payable as hereinafter set forth (the "Stock Price"). In addition, Braun shall be entitled to all earnings which are earned with respect to the funds deposited into the Escrow (the "Earnings").

In any event, the total amount of the Stock Price shall be delivered by Biopure to the Escrow Agent for deposit into the Escrow Account not later than the fifth anniversary of the date of this Agreement. Biopure shall have the right at any time to make additional payments to the Escrow and to accelerate the purchase of the Shares upon the deposit with the Escrow of the entire unpaid Stock Price.

(d) When the sale of any of the Shares is consummated hereunder, the certificates for such Shares and the related stock powers shall be delivered by the Escrow Agent to Biopure, and all right, title and interest in and to the Shares shall thereafter vest in Biopure and the purchase price and all Earnings shall be paid by the Escrow Agent to Braun. 7. Taxation Indemnity. (a) If Braun provides Biopure and the escrow agent with an executed ownership certificate (U.S. Internal Revenue Service Form 1001), then (i) neither Biopure nor the escrow agent shall withhold any tax pursuant to Section 1441 of the Internal Revenue Code (the "Code") from any payment to be made to Braun pursuant to Section 6 herein and the Escrow Agreement; and (ii) Biopure shall indemnify and hold harmless Braun from and against any liability or claim for income tax that may be asserted by the Internal Revenue Service against Braun by reason of said payments whether such claim is based upon Sections 881 (with respect to interest income only), 483, 1273 or 1274, as the same now exists or may hereinafter be amended, or any corresponding or successor provision. (b) This covenant shall terminate if Braun: (i) assigns its beneficial ownership interest in the Purchase Agreement or (ii) fails to qualify for a withholding exemption under the U.S.-German tax treaty or (iii) fails to renew the ownership certificate upon its expiration. 8.
