SYNOPSYS ACCEPTS SHARES IN NUMERICAL TENDER OFFER AND

COMMENCES SUBSEQUENT OFFERING PERIOD UNTIL 12:00 MIDNIGHT, 

NEW YORK CITY TIME ON THURSDAY, FEBRUARY 27, 2003

FTC and Taiwan Antitrust Clearance Received

MOUNTAIN VIEW, Calif., February 25, 2003 – Synopsys, Inc. (Nasdaq: SNPS) announced today that Synopsys’ wholly owned subsidiary, Neon Acquisition Corporation, has accepted for purchase all shares properly tendered in its tender offer for all the outstanding shares of common stock of Numerical Technologies, Inc. (Nasdaq: NMTC), for $7.00 net per share in cash through the expiration of the offer at 12:00 midnight, New York City time, on Monday, February 24, 2003.

The depositary for the offer has advised Synopsys and Neon Acquisition that, as of the expiration of the offer, an aggregate of approximately 31,043,045 Numerical shares were tendered to Neon Acquisition pursuant to the offer, including approximately 8,566,909 shares delivered through notices of guaranteed delivery, representing approximately 91.15% of the Numerical shares outstanding.

Synopsys also announced that Neon Acquisition is providing and has commenced a subsequent offering period for all remaining untendered shares which will expire at 12:00 midnight, New York City time, on Thursday, February 27, 2003, unless further extended, to permit stockholders who have not yet tendered their shares the opportunity to do so. All shares validly tendered during this subsequent offering period will be immediately accepted and the tendering stockholders will be promptly paid after acceptance. The same $7.00 per share

price offered in the prior offering period will be paid during the subsequent offering period. Shares tendered in the prior offering period or during the subsequent offering period may not be withdrawn.

Synopsys further announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act expired and that it had received notice from the Taiwan antitrust authorities that they would not exercise jurisdiction over the acquisition.

Pursuant to the terms of the merger agreement among Synopsys, Neon Acquisition and Numerical, after the expiration of the subsequent offering period, Neon Acquisition will acquire the Numerical shares that it and Synopsys do not then own at the same $7.00 per share price as offered in the tender offer, through a merger of Neon Acquisition with and into Numerical. As a result of this merger, Numerical will become a wholly owned subsidiary of Synopsys.
