FOR IMMEDIATE RELEASE

           MENTOR GRAPHICS EXTENDS TENDER OFFER FOR IKOS SYSTEMS, INC.

         WILSONVILLE, OR - MARCH 13, 2002 - Mentor Graphics Corporation (Nasdaq:
MENT) today announced that in connection with its Agreement and Plan of Merger
and Reorganization with IKOS Systems, Inc., it has extended its $11.00 per share
cash tender offer for all outstanding shares of the common stock of IKOS
Systems, Inc. (Nasdaq: IKOS) to 12:00 Midnight, New York City time, on Tuesday,
March 26, 2002, unless further extended. The tender offer was previously
scheduled to expire at 12:00 Midnight, New York City time, on Friday, March 15,
2002.

As of the close of business on March 12, 2002, 558,002 shares of IKOS common
stock had been validly tendered into the offer, which, together with the 841,600
shares already beneficially owned by Mentor, represents approximately 14.5% of
IKOS' outstanding common stock (based upon 9,662,314 shares outstanding as of
March 6, 2002). The shares tendered represent approximately 5.8% of the
outstanding common stock.

The IKOS Board has unanimously approved the Mentor tender offer and merger and
unanimously recommends that IKOS stockholders tender their shares in the offer.
Following completion of the tender offer, the merger agreement provides for
Mentor to consummate a second-step merger in which those shares not tendered
will be converted into the right to receive $11.00 per share in cash. Closing of
the tender offer is conditioned on shares being tendered which, together with
shares held by Mentor, constitute more than 50% of the fully-diluted common
stock of IKOS. If 90% of the outstanding shares are held by Mentor following
completion of the tender offer, the second-step merger can be completed without
a vote or meeting of IKOS' stockholders.

and IKOS has previously filed a solicitation/recommendation statement regarding
the acquisition. Mentor and IKOS will file an amended tender offer statement and
