announced the settlement of the litigation entitled Cadence Design Systems, Inc. et al. v. Avant! Corporation et al., pending in the United States District Court for the Northern District of California. Pursuant to the settlement, Cadence, Avant!
and the individuals named in the litigation have agreed to dismiss all pending claims and counterclaims in the litigation and to release all claims they made or could have made in the litigation. Under the agreement, Cadence will be paid $265
million. In addition, Cadence, Avant! and Synopsys, as the acquirer of Avant!, have entered into reciprocal licenses covering the intellectual property at issue in the litigation. </FONT></DIV> <DIV><FONT SIZE="1">&nbsp;</FONT></DIV> <DIV><FONT

protect and thereby enable innovation. With the litigation behind us, our resources&nbsp;&#150; and those of Synopsys &#150; can be more focused on providing solutions for the technology challenges faced by our customers. I believe that the
electronic design industry now can move forward in a spirit of cooperation and healthy competition.&#148; </FONT></DIV> <DIV><FONT SIZE="1">&nbsp;</FONT></DIV> <DIV><FONT FACE="Times New Roman" SIZE="2" COLOR="#000000">&#147;We are pleased to have

Today&#146;s agreement puts this matter to rest for good. We are pleased that we were able to work constructively with Cadence in order to resolve this matter. We are hopeful that the settlement will open a new chapter to a more mature and healthier
electronic design industry going forward.&#148; </FONT></DIV>
