(1)   Assumes conversion of all of the holder’s notes at a conversion price of approximately $26.339 per share of common stock. However, this conversion price will be subject to adjustment as described under “Description of Notes-Conversion Rights”. 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 369,432,477 shares of common stock outstanding as of April 5, 2002. 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.
