Synopsys, Inc. to Acquire Numerical Technologies, Inc.

MOUNTAIN VIEW, Calif. & SAN JOSE, Calif.--(BUSINESS WIRE)--Jan. 13, 2003--Synopsys, Inc. (Nasdaq:SNPS), the market and technology leader for integrated circuit (IC) design software, and Numerical Technologies, Inc. (Nasdaq:NMTC), a leader in lithography-enabling solutions, today announced they have signed a definitive agreement for Synopsys to acquire all outstanding shares of Numerical's common stock for a cash purchase price of $7.00 per share. The acquisition brings together leaders in electronic design automation (EDA) and lithography-enabling solutions, helping to reduce costs and risk for customers designing advanced integrated circuits.

"Design for manufacturing issues will continue to gain importance as designs inevitably shrink toward the 65 nanometer mark. Combining Numerical's lithography-enabling solutions with Synopsys' design tools will enable us to further reduce costs and manufacturing risk for customers involved in creating smaller, faster and more power-efficient chips," said Aart de Geus, chairman and chief executive officer of Synopsys, Inc. "By bringing together our complementary technologies and adding Numerical's well-respected technologists to our team, Synopsys will be able to deliver more complete design-to-silicon solutions to address changing design for manufacturing needs."

"Merging Numerical and Synopsys will help create technology and solutions that speed production of advanced, sub-wavelength ICs and improve yield by transparently embedding mask and lithography requirements into the EDA flow and into tools that designers are currently using," said Naren Gupta, Numerical's interim president and chief executive officer. "We are extremely excited about the merger of these two leaders since we have long believed that the intersection of these two areas can deliver sub-wavelength-enabling solutions to fuel the growth of the semiconductor industry. Our enthusiasm in joining with Synopsys is further driven by Synopsys' unerring commitment to technical excellence."

Structure of the Transaction

The acquisition will be effected by means of a cash tender offer of all of the outstanding shares of Numerical for a cash purchase price of $7.00 per share, followed by a second-step merger in which Synopsys would acquire any untendered Numerical shares at the same price per share. The acquisition is subject to certain conditions, including the tender of a majority of the fully diluted shares of Numerical, receipt of regulatory approvals, and other customary conditions. Synopsys will also assume all outstanding Numerical stock options in the transaction. The total transaction value is approximately $250 million. Synopsys expects the acquisition will be dilutive in fiscal year 2003 by less than 10 cents per fully diluted share on an earnings before goodwill basis, and accretive in fiscal year 2004. The boards of directors of both companies have approved the transaction. In addition, Numerical's executive officers and directors, who collectively own approximately 20 percent of the outstanding shares of Numerical, have agreed to tender their shares to Synopsys in the transaction. The transaction is expected to close during the first calendar quarter of 2003.
