                    GP STRATEGIES ANNOUNCES EFFECTIVENESS OF
               NATIONAL PATENT DEVELOPMENT REGISTRATION STATEMENT

NEW YORK - November 9, 2004 -- GP Strategies Corporation (NYSE:GPX), a global
provider of training, e-Learning solutions, management consulting, engineering,
and simulation services, today announced that the Securities and Exchange
Commission had declared effective National Patent Development's Form S-1
Registration Statement relating to the previously announced spin off of National
Patent Development Corporation by GP Strategies.

In the spin off, holders of record on November 18, 2004 of GP Strategies common
stock and Class B capital stock will receive one share of National Patent
Development common stock for each share of GP Strategies common stock or Class B
capital stock owned. Shares of National Patent Development common stock are
expected to be distributed on or about November 24, 2004. Copies of the
prospectus included in such Registration Statement will be mailed at the same
time as the shares of National Patent Development common stock are distributed.

GP Strategies common stock will not trade ex-dividend until after the
distribution. As a result, any record holder of GP Strategies common stock that
sells its shares after the record date and on or before the date of distribution
will also be selling its right to receive shares of National Patent Development
common stock in the spin off. Investors are encouraged to consult with their
financial advisors regarding the specific implications of selling their GP
Strategies common stock before the spin-off.

Following the spin off, GP Strategies will cease to have any ownership interest
in National Patent Development, which will become an independent publicly traded
company. National Patent Development common stock will be quoted on the OTC
Bulletin Board following the date of the distribution under the symbol "NPDVV."

National Patent Development Corporation will own and operate GP Strategies'
optical plastics business through its subsidiary, MXL Industries, Inc., will own
a majority interest in Five Star Products, Inc., a publicly held company that is
a leading distributor in the United States of home decorating, hardware, and
finishing products, and will own certain of GP Strategies' other non-core
assets.
