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 March 27,

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



                                       10


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


     We prepared this table based on the information supplied to us on or before
March 27, 2002 by the selling security holders named in the table. The selling
security holders listed in the above table may have sold or transferred, 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. 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.

     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."
