[_] ================================================================================ DEREGISTRATION OF SECURITIES This Post-Effective Amendment No. 1 amends the Registration Statement on Form S-3 (Registration No. 333-10839) (the "Registration Statement") which registers the resale of $125,000,000 aggregate principal amount of the Registrant's 5 5/8% Convertible Subordinated Notes due 2006 (the "Notes") issued in a private placement on June 12, 1996, and the resale of up to 3,654,971 shares of the common stock of the Registrant (the "Shares"), which were initially issuable upon conversion of the Notes by any holder of the Notes that did not purchase the Notes under the Registration Statement. The Registration Statement does not cover the issuance of shares of common stock upon conversion of the Notes into shares of common stock. The Securities and Exchange Commission declared the Registration Statement effective on September 3, 1996. Pursuant to the terms of the Registration Rights Agreement, dated June 12, 1996, by and among the Registrant and Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated, UBS Securities LLC, J.C. Bradford & Co. and Wessells, Arnold & Henderson, the Registrant's obligation to maintain the effectiveness of the Registration Statement has expired. In addition, the Notes and the Shares are no longer restricted securities and are therefore no longer required to be offered by the holders thereof in registered resale transactions described in the prospectus filed as part of the Registration Statement. Accordingly, this Post-Effective Amendment No. 1 is being filed to deregister the Notes and the Shares.
