EXPLANATORY NOTE

Pursuant to a registration statement on Form S-8 (the “2003 Registration Statement”) filed with the Commission on September 23, 2003 (File No. 333-109043), the Registrant registered 1,000,000 shares of its Common Stock, $0.01 par value per share (“Common Stock”), issuable in connection with the Registrant’s 1996 Equity Incentive Plan (the “1996 Plan”). On March 8, 2005, the Registrant’s Board of Directors adopted the 2005 Equity Incentive Plan (the “2005 Plan”) as a replacement for the 1996 Plan which was then terminated. The number of shares issuable under the 2005 Plan will be increased by (1) the number of shares of Common Stock reserved under the 1996 Plan but not subject to stock options plus (2) the number of shares that would otherwise have reverted to the share reserve of the 1996 Plan as a result of, for example, expiration, termination or forfeiture of awards under the 1996 Plan (such shares of Common Stock referred to in (1) and (2) above, the “Unused Shares”).

This Post-Effective Amendment No. 1 to the 2003 Registration Statement is being filed for the purpose of disclosing that the Unused Shares are being moved to a registration statement on Form S-8 filed on or about the date hereof, registering the Unused Shares plus an additional 100,000 shares of Common Stock issuable pursuant to stock based awards to be issued under the Company’s 2005 Plan.
