(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.
