We have prepared this table based on information given to us by the selling securityholders listed below prior to the date hereof.

This conversion rate is subject to adjustment as described under "Description of the Debentures -- Conversion Rights." As a result, the number of shares of common stock issuable upon conversion of the Debentures may increase or decrease in the future. Excludes shares of common stock that may be issued by us upon the repurchase of the Debentures by us at the option of the holder. In addition, excludes fractional shares. Holders will receive a cash adjustment for any fractional share amount resulting from conversion of the Debentures, as described under "Description of the Debentures -- Conversion Rights." (2) Calculated based on 368,766,826 shares of common stock outstanding as of December 17, 2002. In calculating this amount for each holder, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that holder's Debentures, but we did not assume conversion of any other holder's Debentures. (3) Represents holders of Debentures who have not yet provided us with the information necessary to name them in this prospectus. Information about these other selling securityholders will be set forth in prospectus supplements, if required. (4) Assumes that any other holders of Debentures, or any future transferees, pledgees, donees or successors of or from any such other holders of Debentures, do not beneficially own any common stock other than the common stock issuable upon conversion of the Debentures at the initial conversion rate. INVESTING IN THE DEBENTURES INVOLVES RISKS. SEE "RISK FACTORS" BEGINNING ON PAGE 10 OF THE PROSPECTUS. --------------------- We will not receive any of the proceeds from the sale of the Debentures or the underlying shares of common stock by any of the selling securityholders.
