                                   ----------

         This prospectus supplement supplements our prospectus dated March 27,
2001 relating to the sale by certain of our securityholders or by their
transferees, pledgees, donees or other successors of up to $150,000,000
principal amount at maturity of our 4 1/2% Convertible Subordinated Notes due
2005 and the shares of our common stock issuable upon their conversion. You
should read this supplement in conjunction with the prospectus. This supplement
is qualified by reference to the prospectus, except to the extent the
information in this supplement supersedes the information contained in the
prospectus.

                             Selling Securityholders

         The following table provides information regarding the principal amount
at maturity of notes owned beneficially by certain of our selling
securityholders, the percentage of outstanding notes held by such
securityholders, and the number of shares of our common stock each
securityholder would own beneficially upon conversion of its entire principal
amount of notes.

         The table below supplements or amends the table of securityholders
contained on pages 42 through 44 of the prospectus. Accordingly, the information
contained in the table supersedes the information in the prospectus with respect
to each securityholder listed below. This information was furnished to us by the
listed securityholders on or before April 10, 2001. Because selling
securityholders may at any time trade all or some of the notes listed without
providing notice of such transactions to us, the table below may not reflect the
exact value of notes held by each selling securityholder on the date hereof.
