Intergraph Reaches Patent Settlement with AMD - License Terms Include $10 Million Cash Payment and Up to $5 Million per Year for Three Years

HUNTSVILLE, Ala., April 12, 2004 – Intergraph Corporation < NASDAQ: INGR> announced today that Advanced Micro Devices, Inc. (“AMD”) has agreed to settle its patent lawsuit filed against Intergraph and to take a license to Intergraph’s Clipper patents. Under the terms of the license, AMD will pay Intergraph $10 million by May 7, 2004 and will make additional cash payments equal to 2% of the AMD Computation Product Group’s pre-tax operating profits, if any, in the 2005, 2006 and 2007 calendar years subject to a cap of $5 million per year.

Commenting on the settlement, Intergraph CEO & President Halsey Wise said, “We are pleased to have resolved our patent issues with AMD. We believe this agreement is in the best interests of our shareholders based on all of the circumstances, including the scope of AMD’s alleged infringement and damage base.”

On January 15, 2004 AMD filed a declaratory patent action against Intergraph. This action asserted that Intergraph’s Clipper System and Processor patents are either invalid or not infringed by AMD’s microprocessor products. The Intergraph Clipper patents relate to computer system memory management technology.

The settlement announced today provides a license to AMD and its customers for Intergraph’s Clipper family of patents and provides for the resolution of all patent litigation between Intergraph and AMD and its customers.

Intergraph was represented in this matter by the law firm of Robins, Kaplan, Miller & Ciresi, L.L.P.
