SELLING SECURITY HOLDERS We originally sold the debentures to Credit Suisse First Boston Corporation (CSFB) on February 28, 2001 in a private placement. CSFB has advised us that it resold the debentures in transactions exempt from the registration requirements of the Securities Act of 1933 to "qualified institutional buyers" (as defined in Rule 144A under the Securities Act) in compliance with Rule 144A. These subsequent purchasers (and their respective donees and transferees for no consideration) may from time to time offer and sell any or all of the debentures or the common stock issuable on conversion of the debentures pursuant to this prospectus. The debentures and the common stock to be offered and sold using this prospectus are being registered pursuant to a registration rights agreement between us and CSFB. In that agreement, we undertook to file a registration statement with regard to the debentures and common stock and, subject to certain exceptions, to keep that registration statement effective for up to two years. The registration statement to which this prospectus supplement and the accompanying prospectus relate is intended to satisfy our obligations under that agreement. The selling security holders named below have advised us that they currently intend to sell the debentures and common stock set forth below pursuant to this prospectus. Additional selling security holders may choose to sell debentures and common stock from time to time upon notice to us. See "Plan of Distribution" in the accompanying prospectus. Before a security holder may use the accompanying prospectus in connection with an offering of securities, the prospectus as supplemented must include the name and amount of debentures and common stock beneficially owned by the selling security holder and the amount of debentures and common stock to be offered. The prospectus as supplemented will also disclose whether any selling security holder selling in connection with that prospectus supplement has held any position, office or other material relationship with us or any of our predecessors or affiliates during the three years prior to the date of the prospectus supplement.
