"BY UNITING THESE HIGHLY SUCCESSFUL COMPANIES, WE ARE CREATING AN EDA INDUSTRY LEADER IN TERMS OF REVENUE, PROFITABILITY, INSTALLED BASE, AND INVESTOR POTENTIAL." Larry Gerhard Chairman, President, and CEO Summit Design "THIS 'MERGER OF EQUALS' WILL CREATE A NEW WINDOWS NT EDA POWERHOUSE." Mike Bosworth Chairman, President, and CEO OrCAD Contact: Abbie Kendall Armstrong Kendall, Inc. 503-672-4681 abbie@armstrongkendall.com For: Al Koob Summit Design, Inc. 503-643-9281 akoob@sd.com And: Dave Bundy OrCAD 503-672-4800 dave.bundy@orcad.com FOR IMMEDIATE RELEASE SUMMIT DESIGN AND OrCAD ANNOUNCE MERGER AGREEMENT Beaverton, Oregon, September 20, 1998 -- Summit Design (NASDAQ: SMMT) and OrCAD(R) (NASDAQ:OCAD) announced today that the companies have agreed to merge. After the merger, the resulting company will serve the worldwide market for Windows NT(R) electronic design automation (EDA) software and complementary workstation-based EDA solutions for the design of a complete range of electronic products, including complex ICs and systems-on-silicon. Summit Design is a leading provider of graphical design entry and verification software tools for electronic design. OrCAD is the leading supplier of Windows NT(R) EDA software and services to electronics companies worldwide. Under the terms of the merger agreement, each outstanding share of OrCAD common stock will be exchanged for 1.05 shares of Summit Design common stock. Outstanding OrCAD options will be assumed by Summit on the same basis. The merger is expected to be accounted for as a pooling-of-interests transaction. The consummation of the merger is subject to certain conditions, including the receipt of all applicable regulatory approvals, the approval of the stockholders of both companies, and other customary conditions. The merger is expected to be completed by year-end. "By uniting these highly successful companies, we are creating an EDA industry leader in terms of revenue, profitability, installed base, and investor potential," stated Larry Gerhard, chairman, president, and CEO of Summit Design. "In my experience, there have been few mergers that make as much sense as the combination of Summit Design and OrCAD. The combination of a (more) powerful inside sales channel and highly experienced field sales organizations will give the new company a differentiated and highly competitive business model that can deliver superior value to customers." "This 'merger of equals' will create a new Windows NT EDA powerhouse," stated Mike Bosworth, chairman, president, and CEO of OrCAD. "Summit and OrCAD each have experienced management teams, extensive product development skills, and substantial distribution channels. Both companies possess key, complementary technology and software products that have made them leaders in the PC and workstation segments of the EDA industry. Combining their attributes and strengths will give the market even higher value design solutions for the NT platform." Larry Gerhard will become chairman and chief executive officer of the combined companies, and Mike Bosworth will serve as president and chief operating officer. It is anticipated that the senior management of both companies will move forward with the new company. The board of directors will consist of members from the boards of directors of both companies, including Larry Gerhard and Mike Bosworth. MARKETS SERVED BY THE NEW COMPANY Together, products from Summit Design and OrCAD address the three overlapping segments of the electronics design market: commodity products, semiconductors, and electronic systems. The combination covers the design spectrum from systems-on-silicon to systems-on-boards. Summit's graphical High-Level Design Automation (HLDA) products enable IC design engineers to create and verify complex IC designs using familiar graphical paradigms such as block diagrams, state machines, flow charts, or truth tables, rather than the less intuitive textual hardware description language (HDL) code required by synthesis and simulation tools. Summit's HLDA products automatically generate optimized HDL descriptions from these graphical designs, and the output can automatically be re-targeted to nearly all of the EDA industry's (more) standard synthesis tools. OrCAD's solutions target electronics systems companies, specifically for the design of field-programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), analog and mixed analog-digital circuits, and printed circuit boards (PCBs). OrCAD's programmable logic design products support devices from Altera, Xilinx, Actel, Lattice, Lucent, and Vantis. The company also provides products and services for the management of component data used in the design process. ABOUT SUMMIT DESIGN Summit Design, Inc.
