In the three months ended June 30, 2012, a private sector customer, a port authority, and the US Army Corps of Engineers, generated 19.1%, 11.3% and 10.6% of revenues, and for the six month period, these same customers generated 13.2% , 9.9% and 15.3% of total revenues, respectively. In the three months ended June 30, 2011, the US Army Corps of Engineers and a state department of transportation generated 22.8% and 13.3% of total revenues. The US Army Corps of Engineers, a state department of transportation and a private sector customer generated 24.4%, 10.9% , and 10.6% of contract revenues in the six month period ended June 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.
