(1) Assumes conversion of all of the holder's debentures at a conversion rate of 14.7167 shares of common stock per $1,000 principal amount at maturity of the debentures, rounded down to the nearest whole number of shares. However, this conversion rate is subject to adjustment as described under "Description of Debentures - Conversion Rights." As a result, the amount of common stock issuable upon conversion of the debentures may increase or decrease in the future. (2) Calculated based on Rule 13d-3(d)(i) of the Exchange Act using 400,800,852 shares of common stock outstanding as of January 11, 2002. Pursuant to that rule, 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 did not assume conversion of any other holder's debentures. None of the selling securityholders have held any principal position, office or had any other material relationship within the past three years with us or our predecessors or affiliates.
