All other holders of LYONs or
future transferees, pledgees, donees, assignees or
successors of any such holders (3)(4)                       $504,713,000         60.8%           3,668,052               2.5%


----------------
* Less than one percent (1%).
(1)      Assumes conversion of all of the holder's LYONs at a conversion rate of
         7.2676 shares of common stock per $1,000 principal amount at maturity
         of the LYONs. This conversion rate is subject to adjustment, however,
         as described under "Description of the LYONs--Conversion Rights." As a
         result, the number of shares of common stock issuable upon conversion
         of the LYONs may increase or decrease in the future.
(2)      Calculated based on Rule 13d-3(d)(i) of the Exchange Act, using
         142,416,505 shares of common stock outstanding as of February 23, 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 LYONs, but we did not assume conversion of any other
         holder's LYONs.
(3)      Information about other selling securityholders will be set forth in
         prospectus supplements, if required.
(4)      Assumes that any other holders of LYONs, or any future pledgees,
         donees, assignees, transferees or successors of or from any such other
         holders of LYONs, do not beneficially own any shares of common stock
         other than the common stock issuable upon conversion of the LYONs at
         the initial conversion rate.

         Investing in the LYONs involves risks that are described in the "Risk
Factors Relating to the LYONs" section beginning on page 12 of the prospectus.

         Neither the Securities and Exchange Commission, any state securities
commission nor any other regulatory body has approved or disapproved of these
securities or determined if this prospectus is truthful or complete. Any
representation to the contrary is a criminal offense.

           The date of this prospectus supplement is July 30, 2001.
