AMERICAN CAPITAL INVESTS $112 MILLION IN ONE STOP BUYOUT™ OF IMPERIAL SUPPLIES

Bethesda, MD - October 22, 2007 - American Capital Strategies Ltd. (Nasdaq:ACAS) announced today that it has invested $112 million in the One Stop Buyout™ of Imperial Supplies LLC, a value-added distributor of after-market components to fleet and facility-based markets. American Capital’s investment takes the form of a senior term loan, senior and junior subordinated debt and preferred and common equity. American Capital is also providing a revolving credit facility. Imperial management is investing in preferred and common equity. Post close, American Capital owns a majority of the Company with Imperial management owning a minority stake. Imperial Supplies was a portfolio company of Norwest Equity Partners prior to American Capital’s investment. 

“We are pleased to be investing in Imperial Supplies whose singular service model sets it apart as an outstanding distributor of after-market components to fleet and facility-based markets,” said Darin Winn, American Capital Regional Managing Director.  “American Capital provided a highly competitive One Stop Buyout™ package with financing across the capital structure. We look forward to supporting Imperial’s proven and committed management team as the Company broadens and deepens its solid market position.”

American Capital has invested directly and through its funds under management over $10.8 billion in the last twelve months, over $8.8 billion year to date and approximately $550 million quarter to date.  Not including funds under management, American Capital has invested over $7.9 billion in the last twelve months, approximately $6.5 billion year to date and over $470 million quarter to date.  For more information about American Capital’s portfolio, click here.

“Imperial holds a unique position in an industry whose growth is supported by the increase in truck transportation volumes and the aging of fleets. At the same time, the Company is less vulnerable to economic cycles given the diversity of the fleets served and the cargo they transport,” said Gregg Newmark, American Capital Managing Director.  “Employing its long established call center service model, Imperial enables customers to maintain corporate-level control of inventory and reordering and as a result significantly lower costs.“

“Imperial’s rapid turnaround times and value-added services such as its forensic spend analysis that reduces duplications and overstock have earned the Company thousands of loyal customers,” said John Neis, American Capital Principal.  “Imperial plans to further expand its diversified customer base, which already includes the top common carriers and national leasing companies, by offering new products and services.”

Founded in 1958, Imperial distributes over 20,000 high margin products across 15 maintenance, repair and operations categories including electrical products, chemicals and paint, air brake products, vehicle parts and accessories and fasteners. Employing a call-center based model, Imperial serves more than 7,250 customers in 14 major end markets including truck rental/lease, private fleets and parcel carriers. Headquartered in Green Bay, WI, Imperial also has distribution facilities in Green Bay, Charlotte, NC, Reno, NV, and Dallas, TX and call centers at its headquarters and in De Pere, WI.

“We welcome American Capital as our new partner,” said Rob Gilson, Imperial Supplies CEO.  “We are impressed with American Capital’s thorough assessment of our company and are confident that its strong support will significantly contribute to our ambitious growth initiatives.”
