(1)      Assumes  conversion of all of the holder's notes at a conversion  price
         of  approximately  $42.43  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
         165,640,334  shares of common stock outstanding as of December 3, 2001.
         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.
