          AMENDMENT OF DIRECTOR STOCK OPTION PLAN BY MERGER INTO AND
           AMENDMENT AND RESTATEMENT AS 1996 EQUITY INCENTIVE PLAN

     Registrant hereby amends its Registration Statement on Form S-8 (Commission
File No.333-61229) filed with the Securities and Exchange Commission
(the "Commission") on August 12, 1998(the "Registration Statement"), to reflect
the merger of the Registrant's 1998 Director Stock Option Plan(the "Director
Plan") into, and the amendment and restatement of, the Registrant's 1996 Equity
Incentive Plan (the "Equity Plan"), as approved by the shareholders of the
Registrant on January 27, 2004.  At the time of the merger, 50,000 shares of
our Common Stock, $0.10 par value (the "common stock"), that hadbeen previously
registered on the Registration Statement had not been issued. The Equity Plan
Was effective as of January 31, 1996, the date on which it was approved by our
stockholders.  The rights and privileges of holders of outstanding options under
the Director Plan continue to be governed by the Director Plan as in effect
before January 27, 2004.   As a result of the merger, 50,000 shares of our
common stock that previously had been available for issuance under the Director
Plan, which includes shares subject to outstanding options originally issued
under the Director Plan that may expire or terminate unexercised or that may
be forfeited, are available for issuance under the Equity Plan.
