American Innovations Acquires Bass-Trigon from Corrpro Companies

AUSTIN, TX & LITTLETON, CO – March 10, 2003: American Innovations, Ltd. (AI) and Corrpro Companies, Inc. (AMEX:CO) announced today that AI has acquired the assets of Bass-Trigon Software from Corrpro for an undisclosed amount. Bass-Trigon will become a division of AI and will continue to operate from its headquarters in Littleton, Colorado and its office in Longview, Texas. Bass-Trigon and Corrpro will maintain their non-exclusive, worldwide distribution arrangement.

Bass-Trigon was formed through the merger of two industry leading software engineering companies: Bass Software and Trigon Software. In 1984, Dr. Jim Bass founded Bass Software to develop and market a system for managing pipeline compliance information. Trigon Software, focused on pipeline risk assessment software, was founded by Mike Gloven in 1992 as a spin-out from Trigon Engineering, a pipeline engineering company headquartered in Denver, Colorado. The two companies merged in 1996 and Bass-Trigon was purchased by Corrpro in 1999.

Bass-Trigon is a leading provider of integrity management solutions, technology and engineering expertise that support pipeline reliability and safety. Technology includes the industry leading Pipeline Compliance System (PCS™) software, the Integrity Assessment Program (IAP™) and the Allegro® handheld computer. These proven solutions help owners and operators of hazardous liquid and natural gas pipelines comply with safety regulations; reduce the cost of field data collection; comply and manage pipeline data and associated corrosion protection system information; identify and quantify areas of high risk and cost of failure; and prioritize, manage and maximize the return on investment associated with pipeline maintenance programs.

As risk management experts, Bass-Trigon serves primarily the global petroleum and natural gas pipeline industry and has deployed more than 1,500 systems throughout the world. In addition to providing "best-in-class" software, BTS supports its customers with a comprehensive suite of engineering consulting services, thereby providing a single source solution to their pipeline risk and integrity management needs.

"Adding Bass-Trigon to the American Innovations family is a natural fit," explains AI President Rich Smalling. "We are bringing together companies that are dedicated to providing reliable pipeline integrity and compliance solutions to oil and gas customers. The companies have very compatible, entrepreneurial cultures and serve many of the same clients."

AI's Bullhorn® remote monitoring system is an ideal solution for monitoring pipeline rectifiers and test points, compressors, tanks, city gates, gas meters and more. The Bullhorn system uses the MicroBurst™ wireless network from Aeris.net to transfer information from remote equipment to a central database. In seconds, data packets are transferred from the Bullhorn unit over the cellular network to the Aeris.net operating center and on to AI's secure web site where packets are decoded and the data is posted for customers to view or to download.

"Both the Bass-Trigon and Bullhorn product lines help pipeline companies comply with current regulations and make their equipment safer overall," says Lee Blankenstein, VP of Sales and Marketing. "With Bullhorn and Bass-Trigon, customers have a total pipeline integrity solution using the best technologies available."

"We are excited to be acquired by American Innovations, and expect that their commitment to Bass-Trigon will continue to fuel our success in the delivery of reliable, customer focused solutions to support safe pipeline operations", says Mike Gloven, President of Bass-Trigon. "AI is a great partner to support the broadening of our overall offer of pipeline integrity management supported by practical technology innovation. We are also pleased that Corrpro has agreed to continue to offer the Bass-Trigon product line to its customers and alliance partners".

Corrpro was represented in this transaction by Brown, Gibbons, Lang & Company (BGL), a leading investment bank with offices in Cleveland and Chicago.
