MOUNTAIN VIEW, California. May 14, 2002 - Synopsys, Inc. (Nasdaq: SNPS), today

Financial Officer.

The date of the conference call has been changed from May 22, 2002 (the date

guidance for the combined company. Synopsys issued a press release announcing
preliminary results for the second quarter on May 6, 2002.

approximately one week before the date of the call.
