      This prospectus supplement should be read in conjunction with the
prospectus dated April 21, 2004, which is to be delivered with this prospectus
supplement, and this prospectus supplement is qualified by reference to the
prospectus, except to the extent that the information in this prospectus
supplement supercedes the information contained in the prospectus. This
prospectus supplement is not complete without, and may not be delivered or
utilized except in connection with, the prospectus, including any amendments or
supplements to it.

                                -----------------

      The date of this prospectus supplement is May 28, 2004.

      The information in the table appearing under the heading "Selling
Securityholders" beginning on page 46 of the prospectus is amended by adding the
information below with respect to persons not previously listed in the
prospectus, and by superceding the information with respect to persons listed in
the prospectus that are listed below.



      The following table sets forth certain information as of May 17, 2004,
except where otherwise noted, concerning the principal amount of notes
beneficially owned by each selling securityholder and the number of shares of
common stock that may be offered from time to time by each selling
securityholder under this prospectus. The information is based on information
provided by or on behalf of the selling securityholders. The number of shares of
common stock issuable upon conversion of the notes shown in the table below
assumes conversion of the full amount of notes held by each holder at an initial
conversion price of $10.65 per share. This conversion price is subject to
adjustments in certain circumstances. Because the selling securityholders may
offer all or some portion of the notes or the common stock issuable upon
conversion of the notes, we have assumed for purposes of the table below that
the named selling securityholders will sell all of the notes or convert all of
the notes and sell all of the common stock issuable upon conversion of the notes
offered by this prospectus. In addition, the selling securityholders identified
below may have sold, transferred or otherwise disposed of all or a portion of
their notes since the date on which they provided the information regarding
their notes in transactions exempt from the registration requirements of the
Securities Act. Information about the selling securityholders may change over
time. Any changed information given to us by the selling securityholders will be
set forth in prospectus supplements if and when necessary.
