(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." 11
