Huntsville, Alabama, USA, November 29, 2006 – Intergraph Corporation, a provider of spatial information management (SIM) software, today announced the completion of the acquisition of Intergraph by an investor group led by Hellman & Friedman LLC and Texas Pacific Group.

Intergraph had announced on August 31, 2006 a definitive agreement with the investor group regarding the acquisition of the Company in a transaction valued at approximately $1.3 billion. Under the terms of the agreement, Intergraph stockholders will receive $44.00 in cash, without interest, for each share of Intergraph common stock held.

Intergraph stock will cease to trade on the NASDAQ Global Select Market at market close today and will no longer be listed. Intergraph has appointed Computershare Shareholder Services, Inc. as paying agent, and, as soon as practicable, will mail a letter of transmittal and instructions to all Intergraph stockholders of record.
