NEW YORK, NY — (MARKET WIRE) — 11/05/07 — Prospect Capital Corporation (NASDAQ: PSEC)(“Prospect”) announced today that it has made two additional debtinvestments aggregating $8 million.

Prospect has made a follow-on secured debt investment of $3 million intoits existing controlled portfolio company NRG Manufacturing, Inc.

With theacquisition of Dynafab, NRG now manages three manufacturing facilities withover 200 employees, all located in the Houston area. The acquisition hasstrengthened NRG’s position as a leading manufacturer of oilfieldequipment.

“NRG has tripled its EBITDA through organic growth since our initialinvestment in September 2006, and this acquisition will expand NRG’scapabilities significantly,” said Bart J. de Bie, a Managing Director withProspect Capital Management. “NRG’s management has done a superb job ofgrowing its revenues and profits. We are delighted to be in business withthis first-class management team.”

The company currently provides installation,maintenance, repair, construction, and other technical services to bluechip customers in the satellite television, telecommunications, broadbandcable, and cellular industries, and is also evaluating entry into the powerand energy markets.

“These investments illustrate key components of our three-prongedinvestment strategy, which includes ‘Sponsorless,’ ‘Sponsor,’ and ‘Buyout’transaction types,” said Grier Eliasek, President and Chief OperatingOfficer of Prospect. “The first component of our strategy, which we haveexecuted on significantly to date, is a ‘Sponsorless’ transaction in whichwe purchase debt and receive an equity participation ‘kicker’ from acompany controlled by a non-sponsor shareholder group, often managementinstead of a financial institution. Our average realized annualized rate ofreturn to date on these ‘Sponsorless’ financings is 59%. However, we do notearn these high absolute returns on every ‘Sponsorless’ transaction. Whileeach of our writedowns has occurred in a ‘Sponsorless’ transaction, weexpect the ‘Sponsorless’ transaction business, in the aggregate, tocontinue to provide compelling net returns. The second component of ourstrategy, shown by the technical services deal above, is a ‘Sponsor’transaction in which Prospect provides financing to a leading privateequity fund sponsor that risks significant junior capital underneathProspect’s debt, typically investing in a larger and more diversifiedcompany than would Prospect itself without a sponsor. While these ‘Sponsor’financings infrequently offer the opportunity to earn a 59% IRR, we believethey provide significantly enhanced credit quality while adding valuableportfolio diversification. As we continue to adhere to our disciplinedfocus on acceptable leverage multiples and coverage ratios, we see’Sponsor’ financings as attractive reward-to-risk propositions, and we haveincreased our business mix with this transaction type. The third componentof our strategy, shown by the NRG investment above, is a ‘Buyout’transaction in which Prospect, in addition to having a debt instrument, hasreceived controlling ownership and significant equity upside. To date, wehave been successful in acquiring businesses at value-driven prices ofthree to five turns of EBITDA through disciplined screening. We expect toearn our highest absolute returns — and have achieved our highestunrealized returns to date, which we anticipate monetizing in the future –in this third component of our strategy. As we build out an increasinglydiversified portfolio, we expect to continue to pursue all three types ofthese transactions, both within the energy and industrial markets as wellas beyond, and we are pleased with the robustness of our transaction flow.”
