* Less than one percent (1%).

(1)      Assumes conversion of all of the holder's notes at a conversion
         rate of 14.9729 shares of common stock per $1,000 principal amount
         at maturity of the notes. This conversion rate is subject to
         adjustment, however, as described under "Description of the
         Notes-Conversion Rights". As a result, the number of shares 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
         58,084,850 shares of common stock outstanding as of April 30,
         2001. 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 notes, but we did not assume
         conversion of any other holder's notes.

         Investing in the notes or shares of common stock involves risks
that are described in the "Risk Factors" section beginning on page 6 of the
prospectus.

         Neither the Securities and Exchange Commission nor any state
securities commission has approved or disapproved of these securities or
