Prospect Capital Files Preliminary Proxy Statement With SEC in Opposition to Ares\/Allied Merger as Part of Enhanced Bid for Allied Capital

February 1, 2010

NEW YORK, NY — (MARKET WIRE) — 02/01/10 — Prospect Capital Corporation (NASDAQ: PSEC)(“Prospect”) on Friday, January 29, 2010 filed with the Securities and ExchangeCommission a preliminary proxy statement in opposition to the proposed mergerbetween Allied Capital Corporation (“Allied”) and Ares Capital Corporation(“Ares”) in furtherance of Prospect’s increased proposal to acquire Allied madeon January 26, 2010.

“We believe that our increased merger proposal should not only provide superiorvalue to Allied shareholders, when compared to the Ares proposal, but also shouldprovide significant value to Prospect shareholders,” said John F. Barry III,Chairman and CEO of Prospect. “In our view, the credit markets have improvedsignificantly since October when Allied agreed to merge with Ares. We believethe significant improvement in the credit markets likely increases the valueof the Allied portfolio since October and makes Allied asset sales and debtrepayments more feasible. The strong GDP numbers released on January 29 furthersupport our belief that there may be smoother sailing ahead for Allied’sportfolio companies.”

“We also learned from the Ares/Allied amended preliminary proxystatement/prospectus filed on January 26, 2010 that, from September 30, 2009to January 15, 2010, Allied has paid down $389 million of secured debt,significantly reducing the principal payments of Allied debt now required in2010, compared to our previous estimates,” continued Mr. Barry. “We also nowunderstand from these materials that, as of January 15, 2010, Allied had on handapproximately $185 million of cash, money market and similar securities. Thesesignificant debt paydowns, and cash and equivalents on hand, disclosed just sixdays ago, significantly reduce the pro forma leverage of a Prospect-Alliedcombination. In addition, the sale of collateral management agreementsassociated with Allied’s portfolio company Callidus, announced after January15, 2010, may result in an even greater current cash buildup at Allied. In ourview, these factors make Allied a more attractive purchase for Prospect thanbefore.”

“We believe our pending increased merger proposal, if consummated, will deliversignificant benefits to both Prospect and Allied shareholders, includingpotential upside through Allied’s equity positions in a strengthening economy,increased diversification across more than 130 portfolio companies, andamortization of certain fixed costs across a greater asset base,” continued Mr.Barry.

“We are disappointed that, to date, the Allied Board of Directors has notresponded to our increased merger proposal. However, we hope for a constructiveresponse and the opportunity to roll up our sleeves and commence seriousdiscussions with Allied with respect to Prospect’s increased merger proposal,which we believe will create significant value for both Allied and Prospectshareholders,” concluded Mr. Barry.
