         This prospectus supplement supplements our prospectus dated March 27,
2001 and our prospectus supplement dated April 10, 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 and the previous supplement. This supplement is qualified by
reference to the prospectus and the previous supplement, except to the extent
the information in this supplement supersedes the information contained in the
prospectus and the previous supplement.

                             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 and the previous supplement.
Accordingly, the information contained in the table supersedes the information
in the prospectus and the previous supplement with respect to each
securityholder listed below. This information was furnished to us by the listed
securityholders on or before April 17, 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.
