Assumes conversion of all of the Convertible Notes at a conversion price of approximately $23.79 per share of common stock. However, this conversion price will be subject to adjustment as described under "Description of Notes — Conversion Rights" in the prospectus. As a result, the amount of common stock issuable upon conversion of the Convertible Notes may increase or decrease in the future.

(2)
Calculated based on Rule 13d-3(d)(i) of the Exchange Act using 102,926,686 shares of the common stock outstanding as of July 31, 2003. In calculating this amount, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that particular holder's Convertible Notes. However, we did not assume the conversion of any other holder's Convertible Notes.

        We prepared this table based on the information supplied to us on or before October 3, 2003 by the selling security holders named in the table.


        Investing in the Convertible Notes involves risks that are described in the "Risk Factors" section beginning on page 6 of the prospectus.
