Intergraph Announces Agreement to be Acquired by an Investor Group Led by Hellman & Friedman and Texas

On August 31, Intergraph announced the signing of a definitive agreement to be acquired by an investor group led by
Hellman & Friedman LLC and Texas Pacific Group, in a leveraged buyout transaction worth approximately $1.3 billion.
Intergraph investors will receive $44.00 in cash per share of Intergraph common stock, which is a 22% premium over

that Intergraph&apo;s stockholders adopt the agreement, and the voting process to approve the transaction will take place
at a later, undisclosed date.

“We are pleased to announce this transaction which represents the culmination of a thorough review of our standalone
plan and strategic alternatives,” said Sidney L. McDonald, Chairman of the Intergraph Board of Directors. “Our Board
of Directors believes this transaction is in the best interests of our stockholders and underscores the significant
operational and financial improvements Intergraph has made over the past three years.”
