DEREGISTRATION OF SECURITIES
     On November 24, 1998, the Company filed a registration statement on Form S-8 (File No. 333-67899) (the “Registration Statement”) relating to a total of 3,500,000 shares of Class B Common Stock, par value $0.001 per share, and the shares of Class A Common Stock par value $0.001 into which Class B Common Stock could be converted, issuable under its 1998 Equity Incentive Plan (the “Plan”). In September 2003, the

Company effected a recapitalization (“2003 Recapitalization”) by which all of its outstanding Class A Shares and Class B Shares were converted on a one-for-one basis into shares of a single, newly-created class of common stock, par value $0.001 per share (“Common Stock”). As a result of the 2003 Recapitalization, any Class A Shares and Class B Shares issuable under the Plan were converted into shares of Common Stock. This Post-Effective Amendment No. 1 to the Registration Statement hereby deregisters any and all shares of common stock of the Company that were previously registered pursuant to the Registration Statement that have not been sold or otherwise issued as of the date hereof. On October 24, 2003, the Company filed a registration statement on Form S-8 (Registration No. 333-109942) relating to the shares of Common Stock issuable upon exercise of options granted or available for grant under the Plan.
