Item 1.01 Entry into a Material Definitive Agreement

        On March 14, 2005, in connection with its previously announced $50,000,000 share repurchase program, Overstock.com, Inc. (the "Company") entered into a generally non-binding term sheet with IXIS Derivatives Inc. ("IXIS") and/or IXIS Securities North America Inc. The term sheet contemplates a series of transactions between the Company and IXIS that will allow the Company to determine, in advance, the prices at which it may repurchase up to 500,000 shares of its common stock in transactions to be effected by IXIS from time to time. Although the term sheet does not require the Company to enter into any of the contemplated transactions, it does require the Company to indemnify IXIS against losses, claims, damages, liabilities and expenses IXIS incurs under certain circumstances if the Company (i) does not enter into the transactions contemplated by the term sheet, including the cost to IXIS of unwinding any hedging transactions IXIS may enter into in preparation for the execution of the transactions contemplated by the term sheet, or (ii) fails to execute definitive documentation relating to the transactions.

        On March 14, 2005 the Company entered into several transactions with IXIS as contemplated by the term sheet, pursuant to which the Company may be required to purchase up to a maximum of 500,000 shares of its common stock. However, the number of shares that the Company will actually be required to purchase, if any, cannot be determined at present. In connection with these transactions the Company has paid or agreed to pay to IXIS approximately $16.7 million. IXIS has agreed to repay all or a portion of this amount, plus a premium, to the Company, to the extent that the Company is not required to purchase the maximum number of shares.

        To the extent that IXIS delivers shares of common stock to the Company as a result of the transactions described above, the aggregate amount the Company pays or paid to IXIS for the repurchase of the shares as a result of these transactions will reduce the amount the Company might otherwise have spent to directly repurchase shares from time to time under its stock repurchase program.
