(1)  Assumes conversion of all of the holder's notes at a conversion rate of
     29.9458 shares of common stock per $1,000 principal amount at maturity of
     the notes. We adjusted the conversion rate in February 2002 to reflect a
     2-for-1 stock split in our outstanding shares of common stock effected in
     the form of a stock dividend. This conversion rate is subject to further
     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 119,334,571
     shares of common stock outstanding as of September 20, 2002. 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
