American Capital Raises $585 Million Equity Fund; Continues to Expand Asset Management Business

Bethesda, MD – October 5, 2007 – American Capital Strategies Ltd. (Nasdaq: ACAS), with $17 billion of assets under management(1), announced today that it has raised its second private equity fund, the $585 million American Capital Equity II LP (“American Capital Equity II”). The transaction further expands American Capital’s asset management business and further diversifies its investor base, adding six new private equity limited partners. AIG Investments, the asset management arm of American International Group, Inc. (AIG), led the transaction with a consortium of investors including Landmark Partners, Paul Capital Partners, Lehman Brothers Secondary Opportunities Fund and SVG Advisers Limited.

American Capital Equity II is purchasing 17% of American Capital’s equity investments in 80 portfolio companies, for an aggregate cash purchase price of $488 million, subject to adjustments on December 31, 2007. For accounting purposes, the total purchase price includes the $488 million cash purchase price portion, which is 3% below the fair value of these investments on American Capital’s balance sheet at June 30, 2007, and the value associated with an asset management agreement. Through a subsidiary, American Capital LLC, a wholly-owned portfolio company of American Capital, will provide asset management services to American Capital Equity II for a 2% annual management fee on the cost basis of the assets and a 10-30% carried interest in the net profits of American Capital Equity II, subject to certain hurdles. It is anticipated that this will increase American Capital LLC’s revenues by approximately $10 million in the first full year of the agreement. This additional management agreement will be incorporated into the valuation of American Capital LLC and should be accretive to its valuation.

The remaining $97 million committed to American Capital Equity II by the limited partners will be used to fund follow-on investments in the 80 portfolio companies. The transaction occurred in the fourth quarter and the details of the gains and losses on the sale of the equity interests and the increase in fair value of American Capital LLC will be reported as part of American Capital’s year-end earnings release. The proceeds are expected to be used by American Capital for general corporate purposes, including for its investment and lending activities and to repay indebtedness owed under existing revolving credit facilities.

American Capital LLC, a portfolio company of American Capital, now manages six funds with approximately $5.3 billion of third party assets, including European Capital Limited (LSE: ECAS), which was established in 2005. European Capital went public on the London Stock Exchange in May 2007 and has $2.7 billion of assets. Other funds include American Capital Equity I LLC with $0.9 billion in assets, American Capital CLO 2007-1, Ltd. with $0.4 billion of assets, American Capital CLO 2007-2 Ltd. with $0.1 billion of assets and American Capital CRE CDO 2007-1, Ltd. with $0.6 billion of assets.

“We are very pleased to team up with six of the finest private equity fund investors in the world,” said Malon Wilkus, American Capital Chairman, President and CEO. “This transaction increases the assets under management of American Capital affiliates by 10% to a total of 31% of our total managed assets and will contribute to our growing asset management revenue. This highly predictable and recession resistant revenue stream, together with participation in the realized profits of American Capital Equity II, should be accretive to our net operating income per share and our return on equity and thereby contribute to increases in American Capital’s valuation.”

Harvey Lambert, Managing Director and Head of Global Secondaries for AIG Investments commented, “AIG Investments continues to execute transactions in the private equity secondary market and our investment in American Capital Equity II demonstrates the on-going efforts to find and execute the right investment opportunities.”

American Capital LLC, through its subsidiary, will earn approximately $10 million annually in highly predictable and recession-resistant asset management fee income from managing American Capital Equity II. These fees will decline as investments are exited. American Capital LLC anticipates earning incentive fees from its 10-30% carried interest if and when distributions to limited partners exceed their initial investments and subject to certain hurdles.

“During a time when the capital markets are closed for many financial services companies, our ability to raise capital in diverse and flexible ways gives us a tremendous competitive advantage,” said John Erickson, American Capital Chief Financial Officer. “This transaction allowed us to tap a growing set of global investors with significant funds and expertise dedicated to private equity. Our liquidity and ability to fund assets during the market disruption is outstanding.”

In October 2006, American Capital raised its first externally managed U.S. private equity fund, American Capital Equity I LLC, a $1 billion fund. Through June 30, 2007 American Capital Equity I has generated a net 37% compounded annual return to its investors based on the fair value of the investments as of period end.

“Over the past three months, our newest partners have subjected American Capital, including our investment teams, portfolio companies and investment process to extensive due diligence and scrutiny,” said Tom McHale, American Capital Senior Vice President of Finance. “They met with portfolio company management teams and our Investment Teams, interviewed private equity firms with whom we have partnered and reviewed our portfolio company due diligence, valuation reports, third-party due diligence reports and monthly portfolio monitoring information. The decision by these partners, who have a long history of evaluating private equity investments, to participate in this transaction highlights the quality of our investments and the strength of our origination platform.”
