Bethesda, MD - April 4, 2005 - American Capital Strategies Ltd.

"With a loyal customer base, Edge holds a leading market share in the performance electronics aftermarket for trucks," said American Capital Managing Director Frank Do. "Edge's outstanding management team has successfully leveraged the Company's competitive advantages: first to market ability, strong brand recognition, established national distribution channels and unique product features. Edge can use its significant advantages to offer its customers increased driving power and towing capabilities as well as increased fuel economy."

"We are excited to be partnering with Edge, a high caliber company," said American Capital Vice President Joshua Phillips. "Edge's entrepreneurial spirit and dedication to high quality products was instilled by its founders and continues today."

Founded in 1999, Ogden, UT-based Edge designs and manufactures electrical modules and programmers that control the fuel delivery and injection timing on trucks, allowing operators to maximize power, speed, towing capacity and fuel efficiency. The Company also provides in-cab control display monitors that provide a wide range of information to the user such as vehicle diagnostics. Edge's Attitude 2 (A2) in-cab controller won the 2004 Specialty Equipment Market Association (SEMA) New Product of the Year Award. Edge's products are manufactured for major truck manufacturers including Ford, Chevy and Dodge trucks and are distributed through numerous warehouse distributors.

"Our partnership with American Capital is important to Edge's future growth as demand increases for performance electronics in the truck and automotive aftermarket," said Edge CEO Paul Lehman. "With American Capital's financial support and experienced business leadership, Edge is better positioned to expand our coverage of existing markets, address new markets and continue to build Edge brand awareness through extensive sales and marketing efforts."

"American Capital's backing will benefit Edge as demand for our products increases, driven by growth in the number of light and medium-duty trucks, increased market share of diesel powered vehicles and overall growth in the truck and automotive aftermarket, specifically in the performance segment," said Edge President Thomas Carlin.
