March 3, 2003 – Mountain View, CA – Synopsys Inc. a provider of IC design software, completed its acquisition of Numerical Technologies Inc., a provider of subwavelength lithography-enabling technology.

Through a tender offer by its wholly owned subsidiary, Neon Acquisition Corp., Synopsys had previously acquired approximately 90.71% of the outstanding shares of Numerical common stock for a purchase price of $7/share in cash, without interest.

As the final step of the acquisition, Synopsys caused Neon Acquisition to merge with and into Numerical effective March 1, 2003. In the merger, each Numerical share not purchased in the tender offer, other than shares for which statutory appraisal rights are properly exercised, was converted into the right to receive the same $7/share in cash, without interest, as received by Numerical stockholders in the tender offer. As a result, Numerical is now a wholly owned subsidiary of Synopsys.
