AMERICAN CAPITAL INVESTS $9.3 MILLION IN LEADING SIDING MANUFACTURER

Bethesda, MD - April 16, 2003 - American Capital Strategies Ltd. (Nasdaq:ACAS)announced today that it has invested $9.3 million in Nailite International Inc. ("Nailite"), a niche manufacturer of molded polypropylene siding ("MPS") for the remodeling and new construction housing markets. American Capital's investment takes the form of senior subordinated debt with warrants and supports the acquisition of Nailite by Graham Partners. A syndicate led by National City Bank is providing the revolving credit facility and a senior term loan. Nailite management is also investing in the transaction.

"We are pleased to be investing with Graham Partners for the first time," said American Capital COO Ira Wagner. "Graham Partners has significant expertise in plastics processing and building products, which we expect will enhance our investment. We continue to build relationships with private equity sponsors, with this transaction representing the sixteenth time in the past 12 months we have invested for the first time with a private equity sponsor."

American Capital has invested nearly $700 million in the last twelve months.

"With the investment in Nailite, American Capital is backing the absolute leader in design and innovation with a solid brand name, often used as the generic term for injection molded siding, in a rapidly growing, attractive sector of the siding market," said American Capital Principal Ken Jones. "As the only player in the industry solely dedicated to the manufacturing of molded polypropylene siding and with a diversified customer and supplier base, Nailite is in an excellent position to prosper and capture market share in both the remodeling and new construction space."

Founded in 1978, Nailite International Inc. was the first company in the siding business to develop an injection molded siding product that replicates the appearance of the traditional siding materials of natural cedar, brick and stone, thereby offering homeowners the low cost and minimal maintenance benefits of artificial siding without having to sacrifice aesthetics. The company's products are used in the remodeling and construction of homes and serve top national and regional distributors. Nailite offers its customers a wide product offering with proprietary designs, colors and shadings that are difficult to replicate by competitors. Nailite has seen sales more than double since 1997 with annual sales growth of over 20%. The company is based in Miami, FL and has over 140 employees.

"Partnering with American Capital and National City Bank provides the resources to increase Nailite's penetration into the whole-house and new construction segments, as well as enter untapped geographic markets," said Graham Partners Managing Principal Joe May.
