(1)   Assumes conversion of all of the holder’s notes at a conversion rate of 74.5156 shares per $1,000 principal amount of the notes (representing an initial conversion price of approximately $13.42 per share of common stock). However, this conversion price will be subject to adjustment as described in the Prospectus under “Description of Notes—Conversion of Notes.” As a result, the amount of common stock issuable upon conversion of the notes may increase or decrease in the future.
 
(2)   Calculated based on Rule 13d-3(d)(i) of the Exchange Act using 378,750,957 shares of common stock outstanding as of August 8, 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 notes. However, we did not assume the conversion of any other holder’s notes.
