All other holders of LYONs or future
transferees, pledgees, donees, assignees or
successors of any such holders (3)(4)               $306,052,000       36.9%           2,224,263            1.5%

* 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 143,271,377
     shares of common stock outstanding as of November 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.
