Endnotes Basic and diluted Core EPS (excluding professional fees and other costs related to the acquisition of Allied Capital Corporation (the "Allied Acquisition") is a non-GAAP financial measure. Core EPS (excluding professional fees and other costs related to the Allied Acquisition) is the net per share increase (decrease) in stockholders’ equity resulting from operations less professional fees and other costs related to the Allied Acquisition, realized and unrealized gains and losses, any incentive management fees attributable to such realized gains and losses and any income taxes related to such realized gains. Basic and diluted GAAP EPS is the most directly comparable GAAP financial measure. Ares Capital believes that Core EPS provides useful information to investors regarding financial performance because it is one method Ares Capital uses to measure its financial condition and results of operations. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. Reconciliation of basic and diluted Core EPS (excluding professional fees and other costs related to the Allied Acquisition) to the most directly comparable GAAP financial measure is set forth on page 28 hereof. Net income can vary substantially from period to period as a result of various factors, including the recognition of realized gains and losses and unrealized appreciation and depreciation. As a result, quarterly comparisons of net income may not be meaningful. In accordance with ASC 260 (previously SFAS 128) – Earnings per Share, the weighted average shares of common stock outstanding used in computing Core EPS, net investment income per share, GAAP net income (loss) per share and net realized and unrealized gains (losses) per share have been adjusted retroactively by a factor of 1.02% to recognize the bonus element associated with rights to acquire shares of common stock that were issued to stockholders of record as of March 24, 2008 in connection with an equity rights offering. Includes sales to Ivy Hill Middle Market Credit Fund, Ltd. (“Ivy Hill”) and Ivy Hill Middle Market Credit Fund II, Ltd. (“Ivy Hill II”), which are managed by Ivy Hill Asset Management, L.P., a portfolio company of Ares Capital. See discussion of portfolio activity on page 13. The weighted average yield on debt and income producing securities at amortized cost is computed as (a) annual stated interest rate or yield earned plus the net annual amortization of original issue discount and market discount earned on accruing debt included in such securities, divided by (b) total debt and income producing securities at amortized cost included in such securities. The weighted average yield of debt and income producing securities at fair value is computed as (a) annual stated interest rate or yield earned plus the net annual amortization of original issue discount and market discount earned on accruing debt included in such securities, divided by (b) total debt and income producing securities at fair value included in such securities. The weighted average yield of debt and income producing securities at fair value was 13.40% as of June 30, 2010, 12.34% as of March 31, 2010 and 12.60% as of June 30, 2009. Computed as (a) annual stated interest rate on our debt obligations divided by (b) total debt obligations at principal amount. Weighted average investment spread equals weighted average yield of debt and income producing securities at amortized cost minus weighted average cost of debt. Represents gross commitments or fundings less commitments or investments exited, as applicable. Q1-10, Q3-09 and Q2-09 amounts include sales to Ivy Hill of $8.0 million, $5.0 million and $4.0 million, respectively. Q1-10 also includes sales to Ivy Hill II of $86.5 million. Excludes realized and unrealized gains (losses). As of June 30, 2010, 14% of the total investments at fair value or 57% of the floating rate investments at fair value contain interest rate floor features. Includes commitments to portfolio companies for which there are no amounts funded at the end of the period. Computed as total book debt less cash not restricted for dividends or open trades divided by total stockholders equity. Effective rate as of June 30, 2010. For the three months ended June 30, 2010, the weighted average rate was 4.66%. Requires periodic payments of interest only, with the outstanding principal balance due on maturity. Blended pricing across all notes. In October 2008, we entered into a two-year interest rate swap agreement for a total notional amount of $75 million where we pay a fixed interest rate of 2.985% and receive a floating rate based on the prevailing three-month LIBOR. Represents a regular dividend of $0.40 per share and an additional dividend of $0.10 per share. To be paid on September 30, 2010 to stockholders of record on September 15, 2010. Q1-10, Q3-09 and Q2-09 amounts include sales to Ivy Hill of $8.0 million, $5.0 million and $4.0 million, respectively. Q1-10 also includes sales to Ivy Hill II of $86.5 million.

Endnotes (cont’d) EBITDA is a non-GAAP financial measure. For a particular portfolio company, EBITDA typically represents net income before net interest expense, income tax expense, depreciation and amortization. EBITDA amounts are estimated from the most recent portfolio company financial statements, have not been independently verified by ARCC and may reflect a normalized or adjusted amount. Weighted average EBITDA amounts are weighted based on the fair value of the portfolio company investments reported by Ares Capital in its annual report on Form 10-Q for the quarter ended June 30, 2010. Portfolio average total leverage multiples and portfolio weighted average total leverage multiples represent Ares Capital’s last dollar of invested debt capital as a multiple of EBITDA. Portfolio company credit statistics are derived from the most recently available portfolio company financial statements and have not been independently verified by Ares Capital. Accordingly, Ares Capital makes no representation or warranty in respect of this information. Portfolio average interest coverage ratio and portfolio weighted average interest coverage ratio represent the portfolio company’s EBITDA as a multiple of interest and facility fees expense. Portfolio company credit statistics are derived from the most recently available portfolio company financial statements and have not been independently verified by Ares Capital. Based on our investment adviser’s internal investment rating system scale from 1 to 4. Investments with a grade of 4 involve the least amount of risk to our initial cost basis and the trends and risk factors for these investments since origination or acquisition are generally favorable, which may include the performance of the portfolio company or a potential exit. Grade of 1 indicates that the risk to our ability to recoup the cost of such investment has substantially increased since origination or acquisition and our investment advisers does not anticipate we will be repaid in an amount equal to our full initial cost basis.

Internal rate of return is the discount rate that makes the net present value of all cash flows related to a particular investment equal to zero. Internal rate of return is gross of expenses related to investments as these expenses are not allocable to specific investments. Investments are considered to be exited when the original investment objective has been achieved through the receipt of cash and/or non-cash consideration upon the repayment of our debt investment or sale of an investment, or through the determination that no further consideration was collectible and, thus, a loss may have been realized. These IRR results are historical results relating to our past performance and are not necessarily indicative of future results, the achievement of which cannot be assured.
