This Stock Purchase Agreement (this "Agreement"), dated as of February 14, 2003, is between Liberty Media Corporation, a company incorporated in the State of Delaware, United States of America (the "Company"), and Sumitomo Corporation, a company incorporated in Japan (the "Purchaser").

1. Agreement to Purchase and Sell Shares. On the terms and subject to the conditions contained in this Agreement, the Company agrees to issue and sell to the Purchaser and the Purchaser agrees to purchase from the Company 13,336,976 shares of the Company's Series A Common Stock ("Series A Common Stock") (the "Shares"). The number of Shares is equal to the quotient derived from dividing the Purchase Price by the Per Share Purchase Price (both as defined below) rounded up or down, as the case may be, to the nearest whole share.

2. Purchase Price. The purchase price payable for the Shares shall be 1,274.36 Japanese Yen per Share (the "Per Share Purchase Price").

The aggregate purchase price shall be 16,996,122,000 Japanese Yen (the "Purchase Price"). Payment of the Purchase Price shall be made by wire transfer of immediately available Japanese Yen to an account that was designated by the Company to the Purchaser no later than two business days prior to the date of this Agreement.

3. Closing. (a) The closing of the purchase and sale of the Shares pursuant to this Agreement (the "Closing") shall take place on February 14, 2003, New York time (the "Closing Date").

(b) In connection with the Closing:

(1): On or before the close of business New York time on the Closing Date, the Company shall deliver to the Purchaser certificates representing the Shares;
(2): On or before the close of business Tokyo time on February 14, 2003, Purchaser shall deliver to the Company the Purchase Price for the Shares in accordance with Section 2 above; and
