                          DEREGISTRATION OF SECURITIES

      On October 11, 1994, the Company filed a registration statement on Form
S-8 (File No. 33-85010) (the "Registration Statement") relating to a total of
500,000 shares of Class A voting common stock, par value $0.10 per share ("Class
A Shares"), and Class B non-voting common stock, par value $0.10 per share
("Class B Shares"), issuable under its 1983 Stock Option Plan (the "1983 Plan")
and its 1984 Directors and Consultants Stock Option Plan (the "1984 Plan" and
together with the 1983 Plan, the "Plans"). In October 2002, the Company effected
a recapitalization ("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 $0.10 per share ("Common
Stock"). As a result of the Recapitalization, the Class A Shares and the Class B
Shares issuable under the Plans and registered under the Registration Statement
were converted into shares of Common Stock. This Post-Effective Amendment No. 1
to the Registration Statement hereby deregisters any and all Class A Shares and
Class B Shares that were previously registered pursuant to the Registration
Statement that have not been sold or otherwise issued as of the date hereof. On
October, 31, 2002, the Company filed a registration statement on Form S-8
(Registration No. 333-100878) relating to the shares of Common Stock issuable
upon exercise of options granted or available for grant under the Plans.
