Intergraph Announces 3.8 Million Share Accelerated Stock Buyback
Shares Repurchased for $100 Million Subject to Adjustment

HUNTSVILLE, Ala., July 28, 2004 -- Intergraph Corporation (NASDAQ: INGR), a leading global provider of software and services for the management and visual representation of complex information, today announced the Company repurchased 3,797,949 shares from Goldman, Sachs & Co. in a private transaction in connection with an Accelerated Stock Buyback (ASB).  The shares were repurchased for an upfront payment of $100 million or $26.33 per share, subject to a market price adjustment provision based on the volume weighted market trading price over the next nine months. 

Since late 2001, Intergraph has repurchased more than 20 million shares of common stock for approximately $485 million under the open market repurchase program and a modified Dutch tender offer in 2003.  Giving effect to the ASB, the Company has approximately $28 million remaining under its $250 million repurchase program (subject to any accelerated buyback adjustments from today's transaction).

"I am pleased to announce that earlier today we repurchased 3.8 million shares through an Accelerated Stock Buyback (ASB) pursuant to our existing share repurchase program," said Halsey Wise, Intergraph President & CEO.  "As we evaluated our potential uses of cash, we determined that such a share repurchase is a responsible and prudent use of cash.  We believe such actions are evidence that Intergraph's Board and management team understand our responsibility to deploy capital in value-enhancing ways."

As announced separately today, Intergraph's revenue for the second quarter was $138.4 million, an increase of 8.6% from $127.3 million reported in the second quarter of 2003.  For the six months ended June 30, 2004, revenue was $271.3 million, an increase of 9.4% from $247.9 million reported in the same period of 2003. Operating income for the quarter was $9.5 million, or 6.9% of revenue, compared to $2.9 million, or 2.2% of revenue, reported in the second quarter of 2003.  For the six months ended June 30, 2004, operating income was $17.7 million, or 6.5% of revenue, compared to $7.1 million, or 2.9% of revenue, reported in the same period of 2003.
