  Terms Include $9.75 Million Royalty Payment

HUNTSVILLE, Ala., September 28, 2005-- Intergraph Corporation (NASDAQ: INGR), a leading global provider of Spatial Information Management (SIM) software, today announced a patent license agreement between Intergraph's IP subsidiary and Fujitsu Limited, Japan.  Under the terms of the agreement, Fujitsu will make a one-time up-front royalty payment of $9.75 million.  Intergraph expects to record after-tax intellectual property income from this agreement of approximately $5.8 million, net of all fees, expenses and estimated taxes, in the third quarter of 2005.  As a result of the patent license agreement, Fujitsu will obtain a fully paid-up worldwide license to certain Intergraph Clipper patents for specified Fujitsu products.  In addition, Intergraph will obtain an option to take a royalty bearing license to certain Fujitsu patents.

Commenting on the settlement, Intergraph CEO & President Halsey Wise said, “We are pleased to have reached a licensing agreement with Fujitsu.   This license with Fujitsu demonstrates our commitment to realize value from our Intellectual Property."

The Intergraph Clipper patents relate to computer system memory management technology.  The agreement announced today is separate and distinct from the previous PIC patent license for Fujitsu's consumer and embedded electronics products.
