Corrpro Companies Receives $3.6 Million Task Order Under US Navy Contract Valued At Up to $8.0 Million Per Year

Corrpro Companies, Inc. ("Corrpro”), a subsidiary of Insituform Technologies, Inc. (Nasdaq Global Select Market: INSU), announced today that it has received a $3.6 million task order from the United States Navy. This order was received under an existing Indefinite Delivery/Indefinite Quantity (IDIQ) contract valued at up to $8.0 million per year. The United States Navy has the option to renew the contract, which expires in September 2010, for up to four years at a value of up to $8.0 million per year.

The task order requires Corrpro to perform engineering services as well as design and installation of cathodic protection systems, field inspections and surveys in military installations worldwide. It is expected that the majority of the work will be located in the United States, Japan, Korea and the South Pacific Islands. Other locations may include military installations in Western European countries. Corrpro has worked with the US Navy on similar projects for over 15 years. Corrpro recently completed a similar IDIQ contract valued at $4.0 million per year, under which it performed approximately $15.0 million of work over five years.

Spencer Turpin, Regional Vice President of Corrpro said, "We are extremely pleased to perform these services for the US Navy around the world. Identifying and installing cathodic protection systems assists the US Navy in protecting important military infrastructure from corrosion. Our certified engineers and corrosion experts are committed to providing quality service and materials on this project.”

Corrpro was selected to bid on the project after undergoing a thorough pre-qualification process. As the general contractor, Corrpro will work with several subcontractors, including locally-owned small businesses, minority-owned businesses and women-owned businesses.

Corrpro will begin work on this project immediately and expects to complete this portion of the work by August 2010.
