Exhibit 99.1

Allied Capital Board of Directors Rejects Prospect Capital Corporation Offer

February 11, 2010 – Washington, DC – Allied Capital Corporation (NYSE: ALD) announced today that it has issued the following letter in response to Prospect Capital Corporation’s letter dated February 9, 2010.

February 11, 2010

Prospect Capital Corporation
10 East 40th Street
New York, NY 10016
Attention: Mr. John F. Barry III, Chairman and Chief Executive Officer

Dear Mr. Barry:

The Board of Directors of Allied Capital Corporation (“Allied”), together with its external legal and financial advisors, has carefully reviewed and analyzed the revised proposal submitted by Prospect Capital Corporation (“Prospect”) set forth in your letter of February 9, 2010. As a result of this review, Allied’s Board of Directors has unanimously concluded that this revised offer does not constitute, and is not reasonably likely to result in, a “Superior Proposal” as defined under our merger agreement with Ares Capital Corporation (“Ares”). Allied’s Board of Directors has unanimously reaffirmed its recommendation that Allied shareholders vote for the transaction with Ares (the “Ares Merger”) that was announced on October 26, 2009.

We entered into the Ares Merger after careful consideration of the best interests of Allied’s shareholders.

Contrary to the assertions Prospect has made, we would like to assure you that we take very seriously our fiduciary obligations and that we have carefully considered and analyzed each of the three offers you have made to us over the past several weeks. The Allied Board of Directors consists of a majority of independent directors and is advised by two nationally recognized law firms and two investment banking firms, including Sandler O’Neill + Partners L.P., a firm which has no relationship with Ares.

In considering the Ares transaction, the Allied Board carefully considered whether it was the appropriate time to engage in such a transaction and whether Allied should pursue other alternatives simultaneously. As our proxy statement makes clear, both in 2008 and in early 2009, Allied explored a variety of strategic alternatives and held various discussions regarding potential transactions. Following Allied’s debt restructuring in late August 2009 (during which time Allied had terminated discussions with Ares), Ares was the only party that pursued an acquisition of Allied. We did not, and do not, view a call by a Prospect Managing Director to someone on Allied’s Capital Markets desk regarding the acquisition of certain assets as expressing an interest in acquiring Allied.

In reaching the determination to proceed with Ares, the Allied Board considered, with the assistance and advice of its two investment banking firms and outside counsel, whether it would be appropriate to run a process soliciting other potential buyers or merger partners. Based on the prior exploration of alternatives, the Allied Board and its advisors were cognizant of the limited universe of capable, interested buyers for Allied. The Board concluded that the risks and uncertainties associated with such a process outweighed the potential benefits and would have likely resulted in Ares being unwilling to proceed with its proposal. In rendering its advice, our advisors at BofA Merrill Lynch noted that at the request of Allied they had contacted several parties deemed most likely to be interested in and capable of acquiring Allied, but none of the parties demonstrated serious interest in pursuing an acquisition.

The merger agreement we entered into with Ares permits us to negotiate with a party who puts forth a Superior Proposal, and the fact that you have made three offers indicates that the terms of the merger agreement have not deterred you from making a proposal. However, we have been unable to find your offer to be, or be reasonably likely to result in, a Superior Proposal. Casting aspersions on the good faith of the Allied Board and its financial advisors in this process does not add value to your offer, which is what we are called upon to consider and which we have done. Both of our investment banking firms delivered fairness opinions to us with respect to the Ares Merger and both continue to provide analysis and advice with respect to the initial offer and revised offers you have submitted.

In Prospect’s most recent letter you ask why we are rushing to close the Ares Merger. The answer is a simple one: we believe that the Ares Merger is in the best interests of our shareholders for the many reasons we have given.

The consideration to our shareholders remains superior in the Ares Merger.

In Prospect’s revised offer, Allied shareholders would be receiving two components of value: the shares of your stock and the ongoing dividend stream. While Prospect’s revised offer does provide a nominally higher initial premium (assuming Prospect stock price does not deteriorate further), for a variety of reasons we remain very concerned and sensitive to the likelihood that this premium will be significantly reduced or even disappear. These reasons include:

The second component of the consideration for our shareholders is their share of dividends from the combined company. We note that again with your most recent offer, you fail to provide any financial analysis to support your claims that the combined Allied/Prospect can pay higher dividends to our shareholders than the combined Allied/Ares. Prospect’s revised offer letter discusses past dividend history, but does not acknowledge the difficulty of maintaining dividends at the same level following a period of dilutive equity issuances, particularly when you appear to rely so heavily on non-cash items such as the accretion of purchase discount in order to generate net investment income, and that a significant portion of your 2009 dividends represented a return of capital. Unlike the commitment Allied was able to receive from Ares, Prospect has not offered a reduction in management fees as a way to ensure stability of future dividends to our shareholders.

Based upon a review of Prospect’s Form 10-Q as of December 31, 2009, our analysis of your fourth quarter 2009 financial information revealed the following.

Under Prospect’s latest revised proposal, Prospect would be issuing approximately 79.2 million shares to Allied shareholders (surrendering 56% of the combined company). On a pro forma basis, a combined Prospect/Allied would have an estimated 142.6 million outstanding shares and require a quarterly dividend payment at current levels of $0.40875 per share aggregating approximately $58.3 million. With adjusted net investment income (excluding the non-cash accretion of original issue discount on investments of $6.2 million and the one time gain related to the acquisition of Patriot of $5.7 million) for the most recent quarter at Prospect merely $5.1 million, a significant earnings gap arises and appears unlikely to be addressed, even with Allied’s cash earnings added, without a dividend reduction. How the current dividend stream can be supported given the lack of earnings power that Prospect brings to the table is a serious flaw in your proposal that we can not overlook. You have not provided any financial analysis or reassurance to the contrary and therefore we must conclude that our analysis is accurate. We note that on each occasion that Prospect has increased its offer to acquire Allied, it has materially increased the risk that Prospect will not be able to maintain its dividend. This is our primary consideration in determining that your revised offer does not provide superior value to our shareholders.

The Ares Merger presents lower execution risk.

In addition to our viewing future dividends much safer under the Ares Merger, we also again want to point out the far higher likelihood of closing the Ares Merger. Prospect’s offer remains preliminary and subject to due diligence, negotiation of a mutually satisfactory merger agreement, receipt of lender consents and receipt of approval from both Allied and Prospect shareholders. We have significant reservations about the likelihood of a transaction with you closing on the terms you have proposed in your revised offer and you have taken no steps to provide any reassurance to the contrary in your most recent letter. We also note that you still have yet to retain a financial advisor to assist you with this significant and potentially transformational transaction, which continues to cause us concern regarding your ability to execute this transaction as proposed.

***

In your recent letter, you state that this is your “best and final” offer. We have once again analyzed in detail this best and final offer and have unanimously concluded that the revised offer from Prospect does not constitute, and is not reasonably likely to result in, a Superior Proposal. We understand Prospect’s belief that your offer is superior is based in no small part on your optimism – you are optimistic that you will receive early prepayments of indebtedness, you are optimistic that you will be able to redeploy those funds in more favorable investments, you are optimistic that your borrowing capacity will increase and be on better terms, which will enable you to buy portfolios on favorable terms, which will allow you to maintain your dividend, and so on. As fiduciaries to the Allied shareholders, we cannot jettison an existing transaction that we believe is in our shareholders’ best interests for an outcome that depends on so many variable factors playing out favorably. We remain strongly committed to the Ares transaction. Thus, we respectfully request that you terminate your proxy solicitation.

Very truly yours,

THE BOARD OF DIRECTORS
ALLIED CAPITAL CORPORATION
