In the three months ended September 30, 2011, the US Army Corps of Engineers, the US Navy, and two state departments of transportation generated 26.1%, 11.9%13.4% and 12.9% of total revenues, respectively. The US Army Corps of Engineers and a state department of transportation generated 24.6%, and 11.5% of contract revenues in the nine month period ended September 30, 2011.

The Company does not believe that the loss of any one of these customers, other than the US Army Corps of Engineers, would have a material adverse effect on the Company and its subsidiaries and affiliates.

The Company’s long-lived assets are substantially located in the United States.
