AMENDED AND RESTATED STOCK PURCHASE AGREEMENT AMENDED AND RESTATED STOCK PURCHASE AGREEMENT, dated as of May 1, 1999, between BIOPURE Corporation, a Delaware corporation (the "Company"), and Geoffrey J. Filbey an individual residing at 134 North Main Street, Cohasset, MA 02025 (the "Purchaser"). R E C I T A L S: The Company issued and sold to the Purchaser, and the Purchaser purchased from the Company, 41,333.33 shares (the "Restricted Shares") of the Class A Common Stock, $.01 par value per share, of the Company (the "Common Stock") for a purchase price of $1.35 per Restricted Share, pursuant to an Agreement dated as of August 14, 1990 (the "Agreement"). This Amended and Restated Stock Purchase Agreement amends and restates the Agreement, and references herein to "Agreement" shall mean the Agreement as amended and restated herein. The Purchaser contributed the Restricted Shares to Biopure Associates Limited Partnership II ("BALP II") in exchange for a limited partnership interest in BALP. Under section 3.8 of the Agreement of Limited Partnership of BALP II dated September 12, 1999, as amended (the "BALP II Agreement"), any limited partner may elect to have BALP II redeem his or her limited partnership interests for Common Stock under certain specified circumstances, including the consummation by the Company of an initial public offering and the receipt by the Company of U.S. FDA approval in the United States. The stock transfer restrictions and the other terms and conditions of the Agreement were conditions to the Company's agreement to issue and sell the Restricted Shares to the Purchaser. The Restricted Shares consist of "non-lapse" restricted stock, namely Common Stock sold at a discount of $4.05 from the amount determined at the time to be the Fair Market Value per share of the Common Stock, or $5.40. The discount at the Prescribed Rate is $7.92 per share at May 1, 1999 (the "Restriction Amount"). Under the Agreement, the Company has a right of first refusal to acquire the Restricted Shares at a price equal to Fair Market Value of a Restricted Share less an amount equal to the discount plus interest on the discount at the Prescribed Rate. The Restricted Shares were issued as a means to enable employees to acquire an equity interest in the Company and as an incentive to those employees to continue to use their efforts to cause an enhancement in the value of the Common Stock. The Board of Directors of the Company have concluded, at a meeting held June 24, 1999, that it would be in the Company's best interests to <PAGE> 2 maintain Common Stock held by BALP II in BALP II for a period of time following the Company's initial public offering while the Company's assets may be undervalued in the market and to amend the conditions governing the Restricted Shares. Such amendments are intended to restore the originally intended benefit to the employees and to provide for a means to eliminate, in exchange for payment of the Restriction Amount, the non-lapse restriction, for repayment of employee indebtedness to the Company and for the retention of Restricted Shares in BALP II. NOW, THEREFORE, in consideration of the premises and the covenants, promises and agreements hereinafter set forth, it is hereby agreed as follows: 1. DEFINITIONS. As used herein, the following terms not otherwise defined herein have the following respective meanings, unless the context otherwise requires: "COMPANY NOTE" shall mean the Purchaser's promissory note, if any, dated as of August 14, 1990, payable to the Company, evidencing a loan made by the Company to the Purchaser to fund a portion of the purchase price for the Shares. "FAIR MARKET VALUE" of a Restricted Share shall mean the value of one Restricted Share on a given date as determined in good faith by the Board of Directors of the Company, taking into account the restrictions on the Restricted Shares contained in this Agreement, and that because of such restrictions, there is no public market for such Restricted Shares. If there is a public market for the Common Stock, "FAIR MARKET VALUE" shall mean the closing price on the principal exchange on which the Common Stock is traded on the trading day before the date of determination. "PRESCRIBED RATE" shall mean, for each full or partial calendar year during which interest shall accrue hereunder, the rate per annum equal to the rate of interest announced by Fleet Bank as its base rate (the "Base Rate") as in effect on January 1 of such calendar year (in the case of the 1990 calendar year, as in effect on August 14, 1990). Notwithstanding the previous sentence, if Fleet Bank shall announce, at any time during a calendar year, a Base Rate that is more than 2% higher or lower than the Base Rate in effect on January 1 of such year (or August 14 for 1990), the Prescribed Rate shall be, for the remainder of such calendar year, the Base Rate as announced from time to time during the remainder of such calendar year. "RELATED PERSON" shall, with respect to the Purchaser, mean the spouse, a parent or the issue of the Purchaser or any trust for the benefit of the Purchaser or any Related Person. For purposes of this definition, the word "issue" shall also include -2- <PAGE> 3 issue by adoption, and the word "spouse" shall not include a former spouse who is legally separated from an individual under a decree of divorce or separate maintenance. "RESTRICTION AMOUNT" shall mean $7.92. "TRANSFERABLE AMOUNT" shall mean the number of Restricted Shares not subject to repurchase by the Company pursuant to section 5 hereof. 2.

TRANSFERS TO RELATED PERSONS, ETC. The Purchaser may, from time to time, sell, assign, give or otherwise transfer or dispose of all or any portion of the Transferable Amount of Restricted Shares owned or held by him, or any interest therein, to a Related Person or to the guardian or conservator of the Purchaser or the executors or administrators of the deceased Purchaser; PROVIDED, HOWEVER, that the Restricted Shares so transferred shall in all respects remain subject to this Agreement; PROVIDED, FURTHER, that such Restricted Shares shall be deemed to be held by the Purchaser for purposes of section 5 of this Agreement; and PROVIDED, STILL FURTHER, that such transferee shall, as a condition precedent to any such transfer or disposition of any or all of such Restricted Shares, become a party to this Agreement. Upon such transfer or disposition, the transferee shall have all the rights and obligations, in respect of the Restricted Shares so transferred or disposed of, of the Purchaser. 2.3. CERTAIN SALES AFTER OFFER TO COMPANY. Subject to this section 2 and to other provisions in this Agreement to the contrary, the Purchaser may sell all or any portion of the Transferable Amount of Restricted Shares, if the sale is to a BONA FIDE purchaser and is made only after compliance with all of the following provisions of this section 2.3: (a) NOTICE AND OFFER.

The purchase price for each of such Restricted Shares shall be the Fair Market Value of a share of Common Stock as of the date of termination, less an amount equal to the Restriction Amount. The Purchaser hereby authorizes the Company to apply the proceeds of such repurchases to satisfy all obligations of the Purchaser under the Company Note, by offset or otherwise.

BALP II. Unless waived by the Company, the Purchaser shall not make any election to cause the redemption by BALP II of Purchaser's partnership interest related to Restricted Shares, prior to the second anniversary of the closing of the Company's initial public offering.

The Company may exercise this right by 60 days written notice to the Purchaser given at any time during any call period (the "Call Notice"). Any Shares released of their restrictions pursuant to section 8 prior to the end of the 60th day following the Call Notice must be surrendered to the Company for certificates evidencing the Common Stock to be assigned to the Purchaser upon exercise of the Company Call.
