FOR IMMEDIATE RELEASE

           MENTOR GRAPHICS EXTENDS TENDER OFFER FOR IKOS SYSTEMS, INC.


WILSONVILLE, OR - February 26, 2002 - Mentor Graphics Corporation (Nasdaq: MENT)
today announced that it has waived a condition in its tender offer relating to
declines in market indexes and has extended the expiration of its $11.00 per
share cash tender offer for all outstanding shares of the common stock of IKOS
Systems, Inc. (Nasdaq: IKOS). The tender offer which was previously scheduled to
expire at 12:00 Midnight, New York City time, on Friday, March 1, 2002 will now
expire at 12:00 Midnight, New York City time, on Friday, March 8, 2002, unless
further extended.

The condition that has been waived states that there shall not have occurred any
decline in either the Dow Jones Industrial Average, the Standard & Poor's 500
Index or the Nasdaq National Market by an amount in excess of 10% measured from
the close of business on December 7, 2001. Since February 6, 2002, the Nasdaq
National Market has closed on several occasions at a level in excess of 10%
below the level at the close of business on December 7, 2001. This condition,
which is contained in Section 15(2)(c)(4) of Mentor Graphics' Offer to Purchase,
is no longer a condition to Mentor Graphics' tender offer, although the
remaining portions of the conditions have not been waived and continue as
conditions to Mentor Graphics' acceptance of tenders pursuant to its tender
offer.

As of the close of business on February 26, 2002, 461,103 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 13.8% of
IKOS' outstanding common stock (based upon 9,472,974 shares outstanding as of
January 29, 2002). The shares tendered represent approximately 4.9% of the
outstanding common stock.

As announced on December 7, 2001, Mentor Graphics offered to acquire IKOS
Systems for $11.00 in cash per share of IKOS common stock. The offer represents
a premium of 37% over the Nasdaq closing price of IKOS stock on December 6, 2001
and a premium of 49.5% over IKOS' closing price on June 29, 2001, the last
trading day before IKOS announced its proposed acquisition by Synopsys, Inc.
(Nasdaq: SNPS). Furthermore,

the offer represents a premium of 87% over the average closing price of IKOS
stock for the thirty trading days ended December 6, 2001. In addition, Mentor's
offer is subject to fewer conditions than the Synopsys proposal and can be
consummated months earlier than the Synopsys proposal. Mentor's offer is not
subject to any financing condition.
