Intergraph Reaches Global Patent Settlement with Hewlett-Packard

Terms Include $141 Million Cash Payment and Patent Cross License

HUNTSVILLE, Ala., January 21, 2005 -- Intergraph Corporation (NASDAQ: INGR), a leading global provider of Spatial Information Management (SIM) software, announced today that the Company has resolved all pending patent litigation with Hewlett-Packard Company ("HP"), including the Company's OEM Clipper case.  Under the terms of the settlement agreement, HP will pay Intergraph $141 million by January 28, 2005.  Intergraph expects to record approximately $11 million of legal expenses to offset against this settlement in the first quarter of 2005.  The terms of the settlement also provide for the dismissal of all pending legal actions between Intergraph and HP as well as a cross-license to the other party's patent portfolio.

Commenting on the settlement, Intergraph CEO & President Halsey Wise said, "We are very pleased to have fully resolved all of our pending OEM patent litigation with the HP settlement.  We believe that the settlement with HP is in the best interest of our shareholders, and we are pleased to have received a license to HP's extensive patent portfolio for our fields of business.  Intergraph's intellectual property protection and enforcement efforts have produced approximately $860 million of pre-tax income since 2002."

As was previously disclosed, Intergraph announced related patent settlements with Dell, Intel, Gateway and AMD in 2004.  As a technology company, Intergraph will continue to consider potential licensing and litigation strategies to protect its intellectual property.

Intergraph was represented in the litigation by the law firms of Robins, Kaplan, Miller & Ciresi, L.L.P.; McDermott, Will & Emery; Brown McCarroll; Alston & Bird; Ireland, Carroll & Kelley; Parker & Clayton; Richards, Layton and Finger; and Jones & Jones.
