AMERICAN CAPITAL DECLARES ADDITIONAL 2003 DIVIDEND OF $0.06 PER SHARE;
Total 2003 Dividend is $2.79 Per Share

Bethesda, MD - December 12, 2003 - American Capital Strategies Ltd. (Nasdaq:ACAS)announced today that its Board of Directors has declared an additional dividend on its common stock of $0.06 per share payable on January 12, 2004 to shareholders of record as of December 31, 2003. Total dividends declared for 2003 are $2.79 per share, an increase of 9% over 2002.

American Capital must make certain distributions of its taxable income in order to maintain its tax status as a regulated investment company. Investors can refer to the Company's most recent report on form 10-K for more information about its tax status. The Company intends to retain long-term capital gains and treat them as deemed distributions for tax purposes. Therefore, the taxable income that is distributed as dividends would be expected to be treated as ordinary income for tax purposes. Taxable income differs from GAAP income because of both temporary and permanent differences in income and expense recognition. For example, changes in unrealized appreciation and depreciation have no impact on the Company's taxable income. American Capital reports the estimated tax characteristics of each dividend when declared, while the actual tax characteristics of dividends are reported annually to each stockholder on Form 1099DIV. This additional dividend is expected to be a distribution of ordinary income.

A summary of American Capital's dividend history follows. American Capital offers a Dividend Reinvestment Plan (DRIP). For more information regarding this Plan, please visit http://www.americancapital.com/investor_relations/dividends/dividend_reinvestment.cfm for call its Shareholder Relations Department at (301) 841-1359.
