"Selling Security Holders" reads as follows:


                            SELLING SECURITY HOLDERS

         We originally issued the notes in a private placement in December 2001.
The notes were resold by the initial purchasers of the notes to qualified
institutional buyers under Rule 144A under the Securities Act. Selling security
holders may offer and sell the notes and the underlying common stock pursuant to
this prospectus.

         The following table sets forth information we have received as of
August 21, 2002 about the principal amount of notes and the underlying common
stock beneficially owned by each selling security holder that may be offered
using this prospectus.

* Less than 1%.

(1)      Assumes conversion of all of the holder's notes at a conversion rate of
         27.027 shares of common stock per $1,000 principal amount of notes.
         However, this conversion rate 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 30,315,494 shares of common stock outstanding as of
         December 31, 2001. In calculating this amount for each selling security
         holder, we treated as outstanding that number of shares of common stock
         issuable upon conversion of all of that holder's notes. However, we did
         not assume the conversion of any other holder's notes, except in
         calculating the percentage for all selling security holders as a group.

(3)      Information about other selling security holders will be set forth in
         prospectus supplements, if required.

(4)      Column does not add up correctly because the fractional shares to which
         the holders would be entitled have been disregarded.

(5)      Pursuant to an Investment Management Agreement, CALAMOS(R) Investments
         is not acting individually, but solely as an Investment Manager for the
         selling security holder.

(6)      The entity is either an investment company or a portfolio of an
         investment company registered under Section 8 of the Investment Company
         Act of 1940, as amended, or a private investment account advised by
         Fidelity Management and Research Company ("FMR Co."). FMR Co. is a
         Massachusetts corporation and an investment advisor registered under
         Section 203 of the Investment Advisers Act of 1940, as amended, and
         provides investment advisory services to each of such Fidelity entities
         identified above, and to other registered investment companies and to
         certain other funds which are generally offered to a limited

                                       12



         group of investors. FMR Co. is a wholly owned subsidiary of FMR Corp.,
         a Massachusetts corporation. The holdings are as of January 23, 2002.

(7)      The entity owns $1,200,000 of our 6.00% convertible subordinated notes
         due 2004. Further, Morgan Stanley & Co. Incorporated acted as one of
         the initial purchasers in connection with the offer and sale of the
         notes in December 2001.

(8)      The figures in this column are based on information supplied to us, as
         of August 21, 2002, by the respective selling security holders named in
         the table. As of that date, these selling security holders had supplied
         us with information indicating that, collectively, they owned more than
         $200,000,000 aggregate principal amount of notes (which would be
         convertible into more than 5,405,400 shares of common stock),
         reflecting, we believe, that one or more selling security holders
         supplied us with information for inclusion in the table and then sold
         their notes in transactions exempt from the registration requirements
         of the Securities Act to persons who also supplied us with information
         with respect to the same notes. However, since this prospectus would
         not be applicable to any sale of notes after they have been publicly
         sold utilizing this prospectus, no more than $200,000,000 principal
         amount of notes could be sold utilizing this prospectus and,
         accordingly, the $200,000,000 total in this column has been retained
         and represents the maximum principal amount of notes that could be sold
         hereunder.

(9)      The entity also owns an additional $6,500,000 principal amount of the
         notes, which it purchased, in registered form, in the open market.

         We prepared this table based on the information supplied to us on or
before August 21, 2002 by the selling security holders named in the table. The
selling security holders listed in the above table may have sold or transferred,
pursuant to the prospectus or in transactions exempt from the registration
requirements of the Securities Act, some or all of their notes since the date
they have supplied the information to us. Some of the selling security holders
may hold additional notes that have been registered under the Securities Act.
Information about the selling security holders may change further over time. Any
changed information supplied to us will be set forth in future prospectus
supplements.

         Other than as noted above, none of the selling security holders listed
above has, or within the past three years has had, any position, office or other
material relationship with us or any of our predecessors or affiliates.

         Because the selling security holders may offer all or some of their
notes or the underlying common stock from time to time, we cannot estimate the
amount of the notes or the underlying common stock that will be held by the
selling security holders upon the termination of any particular offering. See
"Plan of Distribution."
