Under the terms of the agreement, Intergraph stockholders will receive $44 in cash for each share of Intergraph common stock, representing a 22% premium over Intergraph’s share price.

Intergraph’s Board of Directors has approved the merger agreement and said it will recommend that Intergraph’s stockholders adopt the agreement.
