Summary of Quarterly Results Fourth Fiscal Quarter 2011 Highlights Net investment income for the quarter ended September 30, 2011 was $6.5 million, or $0.30 per share, as compared to $6.0 million, or $0.28 per share, for the quarter ended June 30, 2011. The increase in net investment income was driven by both an increase of our weighted average earning investments of $15.1 million and an increase in our weighted average investment spread of 20 basis points. Net increase in net assets resulting from operations for the quarter ended September 30, 2011 was $3.0 million, or $0.14 per share, as compared to $6.5 million, or $0.31 per share, for the quarter ended June 30, 2011. The decrease in earnings for the quarter ended September 30, 2011 was primarily a result of the following: Unrealized losses on investments of $1.8 million, or $0.08 per share, caused partly by market yield adjustments and partly by credit impairment related to two non-earning investments. Unrealized losses of $1.7 million, or $0.08 per share, caused by mark-to-market adjustments on the broadly syndicated loans referenced in our total return swap (“TRS”). The unrealized loss on the TRS was temporary, and from September 30, 2011 to November 30, 2011, the appreciation on the TRS has been roughly $1.4 million.

Summary of Portfolio Highlights Originations and Net Funds Growth New originations totaled approximately $60 million for the quarter ended September 30, 2011, a decline from an unusually high $136 million in the quarter ended June 30, 2011. Prepayments also slowed during the quarter, allowing for funds growth of approximately $21 million, or nearly 5.0%. Asset Mix We continue to make progress on increasing the proportion of unitranche securities in the portfolio with nearly 70% of our new originations during the quarter in the unitranche product category. Unitranche investments increased to 39% of total investments at September 30, 2011 from 35% of total investments at June 30, 2011. In the current environment, we continue to focus on unitranche investments. However, for the first time in several quarters, we have recently seen some compelling risk/reward opportunities in subordinated debt and have closed several in the quarter ending December 31, 2011.

Portfolio Highlights – Debt Investment Spread Analysis Total yield on investments is calculated as (a) the actual amount earned on such investments, including interest income and amortization of fees and discounts, divided by (b) the daily average of total earning investments at fair value. Interest income yield is calculated as (a) the actual amount earned on such investments, including interest income but excluding amortization of fees and discounts, divided by (b) the daily average of total investments at fair value. The weighted average cost of debt is calculated as (a) the actual amount incurred on such debt obligations, divided by (b) the daily average of total debt obligations. The weighted average investment spread is calculated as (a) the total yield on investments less (b) the weighted average cost of debt.

Credit Quality Credit Quality – Investment Portfolio Fundamental credit quality remains strong, but continued weaknesses in two non-earning investments negatively impacted our quarterly financial results. Non-earning assets represent 0.6% of our loan portfolio at fair value as of September 30, 2011 89.5% of the loans in our investment portfolio at fair value have an investment performance rating of 4 or higher, which is a slight increase from June 30, 2011 and September 30, 2010 Credit Quality – Derivatives Unrealized losses of $1.7 million were primarily caused by mark-to-market adjustments on the broadly syndicated loans referenced in the TRS We view the mark-to-market adjustments on the broadly syndicated loans as temporary as the marks were driven by market yield adjustments and were not due to credit issues. Due to the post September 30, 2011 market rally in the broadly syndicated loan market as well as an increase in the net interest accrued on the TRS, the fair value of the TRS was $(0.5) million as of November 30, 2011, which is a $1.4 million increase from the fair value at September 30, 2011

Liquidity and Investment Capacity Cash and Cash Equivalents Unrestricted cash totaled $46.4 million as of September 30, 2011. Restricted cash totaled $23.4 million as of September 30, 2011. Restricted cash as of September 30, 2011 was primarily held in our securitization vehicle and is available for new investments that qualify for this entity. SBIC Financing As of September 30, 2011, we had $61.3 million in debentures outstanding and $38.7 million in available SBIC debenture commitments. On September 13, 2011, we received exemptive relief from the SEC allowing us to modify the asset coverage requirement to exclude our SBA debentures from this calculation. Senior Secured Revolving Credit Facility As of September 30, 2011, subject to leverage and borrowing base restrictions, we had approximately $72.6 million available for additional borrowings on our revolving credit facility.

Liquidity and Investment Capacity New Investment Activity From October 1, 2011 to November 30, 2011 We made $102.5 million of new investment commitments. 33% were in senior secured debt, 18% were in unitranche investments, 22% were second lien loans, 24% were in junior debt and 3% were in equity securities. Weighted average rate on new debt and income producing securities of 10.7%. We received principal paydowns and payoffs on investments of $33.4 million. Hedging Instrument In September 2011, we entered into ten-year U.S. Treasury futures contracts reflecting a yield of 2.08% to mitigate our exposure to adverse fluctuation in interest rates with a total notional amount of $25 million. The interest rate on our SBA-guaranteed debentures is fixed semi-annually (the “pooling date”) and is based on the ten-year U.S. Treasury rate plus a market spread. The transaction insulates us against adverse changes in the ten-year U.S. Treasury rate for debentures that we have drawn, but for which the rate will not be fixed until the next pooling date.
