|(f) | Approximately 71% of the senior secured loans to the Companys portfolio companies bear interest at a floating rate that may be determined by reference to the
London Interbank Offered Rate (LIBOR) or other base rate (commonly the Federal Funds Rate or the Prime Rate), at the borrowers option. In addition, approximately 35% of such senior secured loans have floors of 1.50% to 3.25% on the LIBOR base
rate. The borrower under a senior secured loan generally has the option to select from interest reset periods of one, two, three or six months and may alter that selection at the end of any reset period. The stated interest rate represents the
weighted average interest rate at December 31, 2010 of all contracts within the specified loan facility.

BlackRock Kelso Capital Corporation

Notes to Financial Statements (Unaudited)

1. Organization

BlackRock Kelso Capital Corporation (the
Company) was organized as a Delaware corporation on April 13, 2005 and was initially funded on July 25, 2005. The Company has elected to be regulated as a business development company (BDC) under the Investment
Company Act of 1940 (the 1940 Act). In addition, for tax purposes the Company has qualified and has elected to be treated as a regulated investment company (RIC) under the Internal Revenue Code of 1986 (the Code).
The Companys investment objective is to generate both current income and capital appreciation through debt and equity investments. The Company invests primarily in middle-market companies in the form of senior and junior secured and unsecured
debt securities and loans, each of which may include an equity component, and by making direct preferred, common and other equity investments in such companies.

On July 25, 2005, the Company completed a private placement of 35,366,589 shares of its common stock at a price of $15.00 per share receiving net proceeds of approximately $529 million. On
July 2, 2007, the Company completed an initial public offering through which it sold an additional 10,000,000 shares of its common stock at a price of $16.00 per share and listed its shares on The NASDAQ Global Select Market. The Company
received net proceeds of approximately $150 million from this offering.

The accompanying financial statements are prepared in
accordance with accounting principles generally accepted in the United States of America (GAAP). In the opinion of management, all adjustments, consisting solely of normal recurring accruals, considered necessary for the fair
presentation of financial statements for the interim periods, have been included. The results of operations for interim periods are not indicative of results to be expected for the full year.

Certain financial information that is normally included in annual financial statements, including certain financial statement footnotes,
prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted herein. These financial statements should be read in conjunction with the Companys financial statements and notes related
thereto included in the Companys Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the Securities and Exchange Commission (SEC) on March 8, 2011.

2. Significant accounting policies

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of income and expenses during the reported period. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ
and such differences could be material.

The significant accounting policies consistently followed by the Company are:



|(a) | Investments for which market quotations are readily available are valued at such market quotations unless they are deemed not to represent fair value.
The Company obtains market quotations, when available, from an
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | independent pricing service or one or more broker-dealers or market makers and may utilize the average of the range of bid and ask quotations as a practical expedient for fair value. However,
debt investments with remaining maturities within 60 days are valued at amortized cost, which approximates fair value. Debt and equity securities for which market quotations are not readily available or for which market quotations are deemed not to
represent fair value are valued at fair value as determined in good faith by or under the direction of the Companys Board of Directors. Because the Company expects that there will not be a readily available market value for substantially all
of the investments in its portfolio, the Company expects to value substantially all of its portfolio investments at fair value as determined in good faith by or under the direction of the Board of Directors using a consistently applied valuation
process in accordance with a documented valuation policy that has been reviewed and approved by the Board of Directors. Due to the inherent uncertainty and subjectivity of determining the fair value of investments that do not have a readily
available market value, the fair value of the Companys investments may differ significantly from the values that would have been used had a readily available market value existed for such investments and may differ materially from the values
that the Company may ultimately realize. In addition, changes in the market environment and other events may have differing impacts on the market quotations used to value some of the Companys investments than on the fair values of the
Companys investments for which market quotations are not readily available. Market quotations may be deemed not to represent fair value in certain circumstances where BlackRock Kelso Capital Advisors LLC, the Companys investment advisor,
believes that facts and circumstances applicable to an issuer, a seller or purchaser or the market for a particular security cause current market quotations to not reflect the fair value of the security. Examples of these events could include cases
where a security trades infrequently causing a quoted purchase or sale price to become stale, where there is a forced sale by a distressed seller, where market quotations vary substantially among market makers, or where there is a wide
bid-ask spread or significant increase in the bid-ask spread.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

With respect to the
Companys investments for which market quotations are not readily available or for which market quotations are deemed not to represent fair value, the Board of Directors has approved a multi-step valuation process each quarter, as described
below:



| | (i) | The quarterly valuation process begins with each portfolio company or investment being initially evaluated and rated by the investment professionals of the Advisor
responsible for the portfolio investment;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | The investment professionals provide recent portfolio company financial statements and other reporting materials to independent valuation firms engaged by the Board of
Directors, such firms conduct independent appraisals each quarter and their preliminary valuation conclusions are documented and discussed with senior management of the Advisor;
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | The audit committee of the Board of Directors reviews the preliminary valuations prepared by the independent valuation firms; and
| | ----- | ---------------------------------------------------------------------------------------------------------------------------------



| | (iv) | The Board of Directors discusses valuations and determines the fair value of each investment in the portfolio in good faith based on the input of the Advisor, the
respective independent valuation firms and the audit committee.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Those investments for which
market quotations are not readily available or for which market quotations are deemed not to represent fair value are valued utilizing a market approach, an income approach, or both approaches, as appropriate. The market approach uses prices and
other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). The income approach uses valuation techniques to convert future amounts (for example, cash flows or earnings)
to a single present amount (discounted). The measurement is based on the value indicated by current market expectations about those future amounts. In following these approaches, the types of factors that the Company may take into account in
determining the fair value of its investments include, as relevant and among other factors: available current market data, including relevant and applicable market trading and transaction comparables, applicable market yields and multiples, security
covenants, call protection provisions, information rights, the nature and realizable value of any collateral, the portfolio companys ability to make payments, its earnings and discounted cash flows, the markets in which the portfolio company
does business, comparisons of financial ratios of peer companies that are public, M&A comparables, the Companys principal market (as the reporting entity) and enterprise values.

Until the end of the second calendar quarter following its acquisition, each unquoted investment in a new portfolio
company generally is valued at cost, which the Advisor believes approximates fair value under the circumstances. As of that date, an independent valuation firm conducts an initial independent appraisal of the investment.

Accounting Standards Codification (ASC) 820-10, Fair Value Measurements and Disclosures (ASC
820-10), issued by the Financial Accounting Standards Board (FASB), defines fair value, establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. ASC 820-10 defines fair value
as the price that the Company would receive upon selling an investment or pay to transfer a liability in an orderly transaction to a market participant in the principal or most advantageous market for the investment. ASC

##### Table of Contents

820-10 emphasizes that valuation techniques maximize the use of observable market inputs and minimize the use of unobservable inputs. Inputs refer broadly to the assumptions that market
participants would use in pricing an asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing an asset or
liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Companys assumptions about the assumptions market participants would use in pricing an asset or
liability developed based on the best information available in the circumstances.

ASC 820-10 establishes a
hierarchy that classifies these inputs into the three broad levels listed below:

Level 1  Valuations
based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Level 2  Valuations based on unadjusted quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

Level 3  Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The
inputs into the determination of fair value may require significant management judgment or estimation. Even if observable market data is available, such information may be the result of consensus pricing information or broker quotes which include a
disclaimer that the broker would not be held to such a price in an actual transaction. The non-binding nature of consensus pricing and/or quotes accompanied by disclaimer would result in classification as Level 3 information, assuming no additional
corroborating evidence.

Transfers between levels, if any, represent the value as of the beginning of the
period of any investment where a change in the pricing level occurred from the beginning to the end of the period.

The Company evaluates the source of inputs, including any markets in which its investments are trading, in determining fair value and categorizes each investment within the fair value hierarchy pursuant
to and consistent with ASC 820-10.

|(d) | Interest income, adjusted for amortization of premium and accretion of discount, and dividend income are recorded on an accrual basis to the extent that the Company
expects to collect such amounts. For loans and securities with payment-in-kind (PIK) income, which represents contractual interest or dividends accrued and added to the principal balance and generally due at maturity, PIK income is
accrued only to the extent that the portfolio company valuation indicates that the PIK income is likely to be collected. Premiums and discounts are determined based on the cash flows expected to be collected for a particular investment. Origination,
structuring, closing, commitment and other upfront fees and discounts and premiums on investments purchased are accreted/amortized over the life of the respective investment. Unamortized origination, structuring, closing, commitment and other
upfront fees are recorded as unearned income. Upon the prepayment of a loan or debt security, any prepayment penalties and unamortized loan origination, structuring, closing, commitment and other upfront fees are recorded as interest income.
Expenses are recorded on an accrual basis.

|(e) | The Company has elected to be taxed as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------

In order to qualify for favorable tax treatment as a RIC, the Company is required to distribute
annually to its stockholders at least 90% of its investment company taxable income, as defined by the Code. To avoid federal excise taxes, the Company must distribute annually at least 98% of its income (both ordinary income and net capital gains).
The Company, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income. If the Company chooses to do so, all other things being equal, this would increase expenses and reduce
the amount available to be distributed to stockholders. The Company will accrue excise tax on estimated excess taxable income as required.

The Company holds 100% of the common stock of certain companies as indicated in the accompanying schedules of investments. The Company carries its investments in such wholly owned companies at fair value
in the statements of assets and liabilities, net of any applicable income tax liabilities. An income tax provision has been provided at the wholly owned company level on all income of such companies, including realized and unrealized gains. Such
wholly owned companies are held in connection with the Companys election to be taxed as a RIC. In general, these wholly owned companies earn income that, if earned directly by the Company, would not be qualifying income for purposes of the
Company qualifying as a RIC. Dividends from these wholly owned companies and gains from the sale of their stock are qualifying income for this purpose. The Company makes investments in securities in accordance with its investment policies through
these wholly owned companies.

|(f) | Dividends and distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by the Board of
Directors. Net realized capital gains, if any, generally are distributed at least annually, although the Company may decide to retain such capital gains for investment.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(g) | Loans or debt securities are placed on non-accrual status, as a general matter, when principal or interest payments are past due 30 days or more or when there is
reasonable doubt that principal or interest will be collected. Accrued interest generally is reversed when a loan or debt security is placed on non-accrual status. Interest payments received on non-accrual loans or debt securities may be recognized
as income or applied to principal depending upon managements judgment. Non-accrual loans and debt securities are restored to accrual status when past due principal and interest is paid and, in managements judgment, are likely to remain
current. The Company may make exceptions to this treatment if the loan or debt security has sufficient collateral value and is in the process of collection.

|(h) | Recently Issued Accounting Pronouncements:
|--- | ------------------------------------------

In January 2010, the FASB issued Accounting Standards Update 2010-06, Fair Value Measurements and Disclosures (ASU 2010-06). ASU 2010-06 amends ASC 820-10 to require new disclosures
with regard to transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements within the Level 3 fair value rollforward. ASU 2010-06 also clarifies existing fair value disclosures about the
appropriate level of disaggregation and about inputs and valuation techniques for both recurring and nonrecurring fair value measurements that fall in either Level 2 or Level 3. The new disclosures and clarifications of existing disclosures were
effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances and settlements in the rollforward of activity in Level 3 fair value measurements, which are
effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. The adoption on January 1, 2010 and January 1, 2011 of the respective additional disclosure requirements of ASU 2010-06
did not materially impact the Companys financial statements.

3. Agreements and related party transactions

The Company has entered into an Investment Management Agreement (the Management Agreement) with the Advisor, under which the
Advisor, subject to the overall supervision of the Companys Board of Directors, manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, the Advisor receives a base
management fee (the Management Fee) from the Company quarterly in arrears at an annual rate of 2.0% of the Companys total assets, including any assets acquired with the proceeds of leverage.

For the three months ended March 31, 2011 and 2010, the Advisor earned $4,465,239 and $4,322,471, respectively, in Management Fees
under the Management Agreement.

The Management Agreement provides that the Advisor or its affiliates may be entitled to an
incentive management fee (the Incentive Fee) under certain circumstances. The determination of the Incentive Fee, as described in more detail below, will result in the Advisor or its affiliates receiving no Incentive Fee payments if
returns to Company stockholders do not meet an 8.0% annualized rate of return during the applicable fee measurement period and will result in the Advisor or its affiliates receiving less than the full amount of the Incentive Fee percentage until
returns to stockholders exceed an approximate 13.3% annualized rate of return during such period. Annualized rate of return in this context is computed by reference to the Companys net asset value and does not take into account changes in the
market price of the Companys common stock.

The Advisor will be entitled to receive the Incentive Fee if the
Companys performance exceeds a hurdle rate during different measurement periods: trailing four quarters periods (which applies only to the portion of the Incentive Fee based on income) and annual periods (which applies only
to the portion of the Incentive Fee based on capital gains). The trailing four quarters periods for purposes of determining the income portion of the Incentive Fee payable for the three months ended March 31, 2011 and 2010 was
determined by reference to the four quarter periods ended on March 31, 2011 and 2010, respectively. The term annual period means the period beginning on July 1 of each calendar year and ending on June 30 of the next
calendar year.

The hurdle rate for each measurement period is 2.0% multiplied by the Companys net asset values at the
beginning of each calendar quarter during the measurement period, calculated after giving effect to any distributions that occurred during the measurement period. A portion of the Incentive Fee is based on the Companys income and a portion is
based on capital gains. Each portion of the Incentive Fee is described below.

Quarterly Incentive Fee Based on Income.For each trailing four quarters period, the Company pays the Advisor an Incentive Fee based on the amount by which (A) aggregate distributions and amounts distributable out of taxable net income (excluding any capital gain and loss)
during the period less the amount, if any, by which net unrealized capital

##### Table of Contents

depreciation exceeds net realized capital gains during the period exceeds (B) the hurdle rate for the period. The amount of the excess of (A) over (B) described in this paragraph
for each period is referred to as the excess income amount.

The portion of the Incentive Fee based on income for each period
will equal 50% of the periods excess income amount, until the cumulative Incentive Fee payments for the period equal 20% of the periods income amount distributed or distributable to stockholders as described in clause (A) of the
preceding paragraph. Thereafter, the portion of the Incentive Fee based on income for the period will equal 20% of the periods remaining excess income amount.

Annual Incentive Fee Based on Capital Gains. The portion of the Incentive Fee based on capital gains is calculated on an annual basis. For each annual period, the Company pays the Advisor an
Incentive Fee based on the amount by which (A) net realized capital gains, if any, to the extent they exceed gross unrealized capital depreciation, if any, occurring during the period exceeds (B) the amount, if any, by which the
periods hurdle rate exceeds the amount of income used in the determination of the Incentive Fee based on income for the period. The amount of the excess of (A) over (B) described in this paragraph is referred to as the excess gain
amount.

The portion of the Incentive Fee based on capital gains for each period will equal 50% of the periods excess
gain amount, until such payments equal 20% of the periods capital gain amount distributed or distributable to stockholders. Thereafter, the portion of the Incentive Fee based on capital gains for the period equals an amount such that the
portion of the Incentive Fee payments to the Advisor based on capital gains for the period equals 20% of the periods remaining excess gain amount. The result of this formula is that, if the portion of the Incentive Fee based on income for the
period exceeds the periods hurdle, then the portion of the Incentive Fee based on capital gains will be capped at 20% of the capital gain amount.

In calculating whether the portion of the Incentive Fee based on capital gains is payable with respect to any period, the Company accounts for its assets on a security-by-security basis. In addition, the
Company uses the period-to-period method pursuant to which the portion of the Incentive Fee based on capital gains for any period is based on realized capital gains for the period reduced by realized capital losses and gross unrealized
capital depreciation for the period. Based on current interpretations of Section 205(b)(3) of the Investment Advisers Act of 1940 by the SEC and its staff, the calculation of unrealized depreciation for each portfolio security over a period is
based on the fair value of the security at the end of the period compared to the fair value at the beginning of the period. Incentive Fees earned in any of the periods described above are not subject to modification or repayment based upon
performance in a subsequent period.

For the three months ended March 31, 2011 and 2010, the Advisor earned zero and
$493,951, respectively, in Incentive Fees from the Company.

The Management Agreement provides that the Company will reimburse
the Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under the Management Agreement, as well as any costs and expenses incurred by the Advisor relating to any
non-investment advisory, administrative or operating services provided by the Advisor to the Company. For the three months ended March 31, 2011 and 2010, the Company incurred $425,485 and $398,664, respectively, for such investment advisor
expenses under the Management Agreement.

From time to time, the Advisor may pay amounts owed by the Company to third party
providers of goods or services. The Company will subsequently reimburse the Advisor for such amounts paid on its behalf. Reimbursements to the Advisor for the three months ended March 31, 2011 and 2010 were $345,520 and $1,358,769,
respectively.

No person who is an officer, director or employee of the Advisor and who serves as a director of the Company
receives any compensation from the Company for such services. Directors who are not affiliated with the Advisor receive compensation for their services and reimbursement of expenses incurred to attend meetings.

The Company also has entered into an administration agreement with BlackRock Financial Management, Inc. (the Administrator)
under which the Administrator provides administrative services to the Company. For providing these services, facilities and personnel, the Company reimburses the Administrator for the Companys allocable portion of overhead and other expenses
incurred by the Administrator in performing its obligations under the administration agreement, including rent and the Companys allocable portion of the cost of certain of the Companys officers and their respective staffs. For the three
months ended March 31, 2011 and 2010, the Company incurred $241,962 and $215,786, respectively, for administrative services expenses payable to the Administrator under the administration agreement.

At March 31, 2011 and December 31, 2010, cash equivalents of $54,379,553 and $1,344,159, respectively, consisted of short term liquid
investments in a money market fund managed by an affiliate of the Administrator.

In March 2011, the Companys Board of
Directors authorized the purchase in a private placement of up to 1,000,000 shares of the Companys common stock, by the Advisor in its discretion, subject to compliance with the Companys and the Advisors applicable policies and
requirements of law. Pursuant to this authorization, during the three months ended March 31, 2011, the Company issued and sold to the Advisor in a private placement 200,000 shares of common stock for $2,000,000 or $10.00 per share, which was the
closing price of the Companys common stock on The NASDAQ Global Select Market on the date of sale.

At March 31, 2011 and December 31, 2010, the Advisor owned and had the right to
vote approximately 215,000 and 47,000 shares, respectively, of the Companys common stock, representing less than 1.0% of the total shares outstanding. On such dates, under compensation arrangements for its officers and employees the Advisor
owned of record but did not have the right to vote an additional 283,000 and 426,000 shares, respectively, of the Companys common stock. At March 31, 2011 and December 31, 2010, other entities affiliated with the Administrator
beneficially owned approximately 4,697,000 and 4,181,000 shares, respectively, of the Companys common stock, representing approximately 6.5% and 5.8% of the total shares outstanding. An entity affiliated with the Administrator has ownership
and financial interests in the Advisor.

Diluted net increase
in net assets per share from operations equals basic net increase in net assets per share from operations for each period because there were no common stock equivalents outstanding during the above periods.

5. Investments

Purchases of investments for the three months ended March 31, 2011 and 2010 totaled $39,551,384 and $16,441,543, respectively. Sales,
repayments and other exits of investments for the three months ended March 31, 2011 and 2010 totaled $4,046,712 and $72,676,277, respectively.

The geographic composition of the portfolio at fair value at March 31, 2011 was United States 95.4% and
Canada 4.6%, and at December 31, 2010 was United States 94.7%, and Canada 5.3%. The geographic composition is determined by the location of the corporate headquarters of the portfolio company.

In the normal course of business, the Company invests in securities and enters into transactions where risks exist due to fluctuations in
the market (market risk) or failure of the issuer of a security to meet all its obligations (issuer credit risk). The value of securities held by the Company may decline in response to certain events, including those directly involving the issuers
whose securities are owned by the Company; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to
issuer credit risk, the Company may be exposed to counterparty credit risk, or the risk that an entity with which the Company has unsettled or open transactions may fail to or be unable to perform on its commitments. The Company manages counterparty
risk by entering into transactions only with counterparties that they believe have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the
Company to market, issuer and counterparty credit risks, consist principally of investments in portfolio companies. The extent of the Companys exposure to market, issuer and counterparty credit risks with respect to these financial assets is
generally approximated by their value recorded in the statements of assets and liabilities. The Company is also exposed to credit risk related to maintaining all of its cash at a major financial institution.

##### Table of Contents

The Company has investments in lower rated and comparable quality unrated senior and junior
secured, unsecured and subordinated debt securities and loans, which are subject to a greater degree of credit risk than more highly rated investments. The risk of loss due to default by the issuer is significantly greater for holders of such
securities and loans, particularly in cases where the investment is unsecured or subordinated to other creditors of the issuer.

6.
Derivatives

The Company may enter into forward foreign currency contracts from time to time to facilitate settlement of
purchases and sales of investments denominated in foreign currencies or to help mitigate the impact that an adverse change in foreign exchange rates would have on the value of the Companys investments denominated in foreign currencies. A
forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date (usually the security transaction settlement date) at a negotiated forward rate. These contracts are marked-to-market by recognizing the
difference between the contract exchange rate and the current market rate as unrealized appreciation or depreciation. Realized gains or losses are recognized when contracts are settled. The Companys forward foreign currency contracts generally
have terms of approximately three months. The volume of open contracts at the end of each reporting period is reflective of the typical volume of transactions during each calendar quarter. Risks may arise as a result of the potential inability of
the counterparties to meet the terms of their contracts. The Company attempts to limit this risk by dealing with only creditworthy counterparties.

At March 31, 2011, details of open forward foreign currency contracts were as follows:

All realized and
unrealized gains and losses on forward foreign currency contracts are included in earnings (changes in net assets) and are reported as separate line items within the Companys statements of operations. Unrealized gains and losses on forward
foreign currency contracts are also reported as separate line items within the Companys statements of assets and liabilities.

The Company holds warrants and options in certain portfolio companies in an effort to achieve additional investment return. In purchasing warrants and options, the Company bears the risk of an unfavorable
change in the value of the underlying equity interest. The aggregate fair value of warrants and options as of March 31, 2011 and December 31, 2010 represents 0.7% and 0.8%, respectively, of the Companys net assets.

The Company may enter into other derivative instruments and incur other exposures with other counterparties in the future.

7. Debt

Under the terms
of the Companys amended and restated Senior Secured, Multi-Currency Credit Agreement (the Credit Facility), as amended on April 20, 2010, certain lenders agreed to extend credit to the Company in an aggregate principal amount
not to exceed $375,000,000 outstanding, at any one time, consisting of $275,000,000 of revolving loan commitments and $100,000,000 of term loan commitments. The Credit Facility is secured by substantially all of the assets in the Companys
portfolio, including cash and cash equivalents. Subject to certain exceptions, pricing for outstanding borrowings is at LIBOR plus an applicable spread of either 3.00% or 3.25%

##### Table of Contents

for revolving loans, based on a pricing grid using the Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility does not contain a LIBOR floor requirement. At
March 31, 2011, the effective LIBOR spread under the Credit Facility was 3.00%. Term loan commitments under the Credit Facility have been fully drawn and, once repaid, may not be reborrowed. The Credit Facility also includes an
accordion feature that allows the Company, under certain circumstances, to increase the size of the Credit Facility by up to an additional $275,000,000 of revolving loan commitments and $250,000,000 of term loan commitments. The Credit
Facility is used to supplement the Companys equity capital to make additional portfolio investments and for other general corporate purposes.

At March 31, 2011, the Company had $100,000,000 drawn on the Credit Facility versus $170,000,000 at December 31, 2010. Subject to compliance with applicable covenants and borrowing base
limitations, the remaining amount available under the Credit Facility was $275,000,000 at March 31, 2011.

On
January 18, 2011, the Company closed a private placement issuance of $158,000,000 in aggregate principal amount of five-year, senior secured notes with a fixed interest rate of 6.50% and a maturity date of January 18, 2016 and $17,000,000
million in aggregate principal amount of seven-year, senior secured notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018 (collectively, the Senior Secured Notes). The Senior Secured Notes were sold to
certain institutional accredited investors pursuant to an exemption from registration under the Securities Act of 1933, as amended. Interest on the Senior Secured Notes is due semi-annually on January 18 and July 18, commencing on
July 18, 2011.

The Companys average outstanding debt balance during the three months ended March 31, 2011 and
2010 was $259,711,111 and $260,746,667, respectively. The maximum amounts borrowed during the three months ended March 31, 2011 and 2010 were $363,000,000 and $314,000,000, respectively. The weighted average annual interest cost for the three
months ended March 31, 2011 and 2010 was 5.16% and 1.53%, respectively, exclusive of commitment fees and of other prepaid expenses related to establishing the Credit Facility and the Senior Secured Notes. With respect to any unused portion of
the commitments under the Credit Facility, the Company incurs an annual commitment fee of 0.50%. Commitment fees incurred for the three months ended March 31, 2011 and 2010 were $321,542 and $125,752, respectively.

At March 31, 2011, the Company was in compliance with all covenants required under the Credit Facility and the Senior Secured Notes.

8. Capital stock

In 2008, the Companys Board of Directors approved a share repurchase plan under which the Company may repurchase up to 2.5 percent of its outstanding shares of common stock from time to time in open
market or privately negotiated transactions. In 2009, the Board of Directors approved an extension and increase to the plan which authorized the Company to repurchase up to an additional 2.5 percent of its outstanding shares of common stock. In May
2011, the repurchase plan was further extended through the earlier of June 30, 2012 or until the approved number of shares has been repurchased. During the three months ended March 31, 2011, the Company purchased a total of 200,000 shares
of its common stock on the open market for $2,003,040, including brokerage commissions. There were no such purchases during the three months ended March 31, 2010. Since inception of the repurchase plan through March 31, 2011, the Company has
purchased 1,161,679 shares of its common stock on the open market for $7,428,940, including brokerage commissions. At March 31, 2011, the total number of remaining shares authorized for repurchase was 1,594,971. The Company currently holds the
shares it repurchased in treasury.

9. Guarantees and commitments

In the normal course of business, the Company may enter into guarantees on behalf of portfolio companies. Under these arrangements, the
Company would be required to make payments to third parties if the portfolio companies were to default on their related payment obligations. The Company has no such guarantees outstanding at March 31, 2011. The Companys only such guarantee
outstanding at December 31, 2010 was terminated on January 17, 2011 with no payments having been made thereunder.

In the
normal course of business, the Company enters into contractual agreements that provide general indemnifications against losses, costs, claims and liabilities arising from the performance of individual obligations under such agreements. The Company
has had no prior claims or payments pursuant to such agreements. The Companys individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred.
However, based on managements experience, the Company expects the risk of loss to be remote.

From time to time, the
Company may be a party to certain legal proceedings incidental to the normal course of its business, including the enforcement of the Companys rights under contracts with its portfolio companies. While the Company cannot predict the outcome of
these legal proceedings with certainty, it does not expect that these proceedings will have a material effect on its financial statements.

10. Fair value of financial instruments

The carrying values of the Companys financial instruments approximate fair value. The carrying values of receivables, other assets, accounts payable and accrued expenses approximate fair value due
to their short maturities. The carrying and fair values of the Companys Credit Facility borrowings were $100,000,000 and $99,500,000 at March 31, 2011 and $170,000,000 and $169,150,000 at December 31, 2010, respectively. The carrying
and fair values of the Companys Secured Senior Notes were $175,000,000 and $175,875,000 at March 31, 2011. The carrying and fair values of the Companys total debt outstanding were therefore $275,000,000 and $275,375,000 at March 31,
2011 and $170,000,000 and $169,150,000 at December 31, 2010, respectively.

The following tables summarize the fair values of
the Companys investments, forward foreign currency contracts and cash and cash equivalents based on the inputs used at March 31, 2011 and December 31, 2010 in determining such fair values:

Overview

We were incorporated in Delaware on April 13, 2005 and were initially funded on July 25, 2005. Our investment objective is to
provide a combination of current income and capital appreciation. We intend to invest primarily in debt and equity securities of private and certain public U.S. middle-market companies.

We are externally managed and have elected to be regulated as a BDC under the 1940 Act. As a BDC, we are required to comply with certain
regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in qualifying assets, including securities of private or thinly traded public U.S. companies, cash, cash equivalents, U.S. Government
securities and high-quality debt investments that mature in one year or less.

Investments

Our level of investment activity can and does vary substantially from period to period depending on many factors, including the amount of
debt and equity capital available to middle-market companies, the level of merger and acquisition activity, the general economic environment and the competitive environment for the types of investments we make.

As a BDC, we must not acquire any assets other than qualifying assets specified in the 1940 Act unless, at the time the
acquisition is made, at least 70% of our total assets are qualifying assets (with certain limited exceptions). Qualifying assets include investments in eligible portfolio companies. Under the relevant SEC rules, the term eligible
portfolio company includes all private companies, companies whose securities are not listed on a national securities exchange, and certain public companies that have listed their securities on a national securities exchange and have a market
capitalization of less than $250 million. These rules also permit us to include as qualifying assets certain follow-on investments in companies that were eligible portfolio companies at the time of initial investment but that no longer meet the
definition.

Revenues

We generate revenues primarily in the form of interest on the debt we hold, dividends on our equity interests and capital gains on the sale of warrants and other debt or equity interests that we acquire
in portfolio companies. Our investments in fixed income instruments generally have an expected maturity of three to ten years, although we have no lower or upper constraint on maturity, and typically bear interest at a fixed or floating rate.
Interest on our debt securities is generally payable quarterly or semi-annually. Payments of principal of our debt investments may be amortized over the stated term of the investment, deferred for several years or due entirely at maturity. In some
cases, our debt instruments and preferred stock investments may defer payments of cash interest or dividends or pay interest or dividends in-kind. Any outstanding principal amount of our debt securities and any accrued but unpaid interest will
generally become due at the maturity date. In addition, we may generate revenue in the form of prepayment fees, commitment, origination, structuring or due diligence fees, fees for providing significant managerial assistance and consulting fees.

Expenses

Our primary operating expenses include the payment of a base management fee and, depending on our operating results, an incentive management fee, expenses reimbursable under the management agreement,
administration fees and the allocable portion of overhead under the administration agreement. The base management fee and incentive management fee compensate the Advisor for work in identifying, evaluating, negotiating, closing and monitoring our
investments. Our management agreement with the Advisor provides that we will reimburse the Advisor for costs and expenses incurred by the Advisor for office space rental, office equipment and utilities allocable to the Advisor under the management
agreement, as well as any costs and expenses incurred by the Advisor relating to any non-investment advisory, administrative or operating services provided by the Advisor to us. We bear all other costs and expenses of our operations and
transactions.

Critical accounting policies

Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been
prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Changes in the economic
environment, financial markets and any other parameters used in determining such estimates could cause actual results to differ. Our critical accounting policies, including those relating to the valuation of our investment portfolio, are further
described in the notes to the financial statements and in Note 2 to the financial statements in the Companys Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on March 8, 2011. See Note 2
to the financial statements in this Quarterly Report for a description of recently issued accounting pronouncements.

Portfolio and investment activity

During the three months ended
March 31, 2011, we invested approximately $39.6 million across two new and several existing portfolio companies. The new investments consisted primarily of senior loans secured by first liens ($35.9 million, or 91% of the total invested) or
second liens ($5.1 million, or 13%), and unsecured or subordinated debt securities and equity securities ($(1.4) million, or (4%), representing the cancellation of an unsettled prior period equity purchase). Additionally, we received proceeds from
sales/repayments and other exits of approximately $4.0 million during the three months ended March 31, 2011.

At
March 31, 2011, our net portfolio of $976 million (at fair value) consisted of 52 portfolio companies and was invested 49% in senior secured loans, 24% in unsecured or subordinated debt securities, 12% in equity investments, 9% in senior secure
notes and 6% in cash and cash equivalents. Our average portfolio company investment at amortized cost was approximately $18.9 million at March 31, 2011. Our largest portfolio company investment by value was approximately $51.6 million and our
five largest portfolio company investments by value comprised approximately 24% of our portfolio at March 31, 2011. At December 31, 2010, our net portfolio of $882 million (at fair value) consisted of 50 portfolio companies and was
invested 50% in senior secured loans, 26% in unsecured or subordinated debt securities, 14% in equity investments, 10% in senior secured notes and less than 1% in cash and cash equivalents. Our average portfolio company investment at amortized cost
was approximately $19.7 million at December 31, 2010. Our largest portfolio company investment by value was approximately $53.1 million and our five largest portfolio company investments by value comprised approximately 26% of our portfolio at
December 31, 2010.

The weighted average yield of the debt and income producing equity securities in our portfolio at
fair value was 12.2% at March 31, 2011 and 12.4% at December 31, 2010. The weighted average yields on our senior secured loans and other debt securities at fair value were 11.0% and 14.2%, respectively, at March 31, 2011, versus 11.3%
and 14.3% at December 31, 2010. The weighted average yield of the debt and income producing equity securities in our portfolio at their current cost basis was 11.4% at March 31, 2011 and 10.9% at December 31, 2010. The weighted
average yields on our senior secured loans and other debt securities at their current cost basis were 10.8% and 12.2%, respectively, at March 31, 2011, versus 10.1% and 12.1% at December 31, 2010. Yields are computed using interest rates
and dividend yields as of the balance sheet date and include amortization of loan origination and commitment fees, original issue discount and market premium or discount based in the expected cash flows of the respective portfolio investment. Yields
exclude common equity investments, preferred equity investments with no stated dividend rate, short-term investments, cash and cash equivalents.

At March 31, 2011, 47% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal Funds Rate or the Prime Rate, and 53% bore interest at fixed rates. The percentage of
our total debt investments that bore floating rate interest based on an interest rate floor was 28% at March 31, 2011. At December 31, 2010, 45% of our debt investments bore interest based on floating rates and 55% bore interest at fixed
rates. The percentage of our total debt investments that bore floating rate interest based on an interest rate floor was 25% at December 31, 2010.

The Advisor employs a grading system for our entire portfolio. The Advisor grades all loans on a scale of 1 to 4. This system is intended to reflect the performance of the borrowers business,
the collateral coverage of the loans and other factors considered relevant. Generally, the Advisor assigns only one loan grade to each portfolio company for all loan investments in that portfolio company; however, the Advisor will assign multiple
ratings when appropriate for different investments in one portfolio company. The following is a description of the conditions associated with each investment rating:



38



---

##### Table of Contents

Grade 1: Investments in portfolio companies whose performance is substantially within
the Advisors expectations and whose risk factors are neutral to favorable to those at the time of the original investment.

Grade 2: Investments in portfolio companies whose performance is below the Advisors expectations and that require closer
monitoring; however, no loss of investment return (interest and/or dividends) or principal is expected.

Grade 3:
Investments in portfolio companies whose performance is below the Advisors expectations and for which risk has increased materially since origination. Some loss of investment return is expected, but no loss of principal is expected. Companies
graded 3 generally will be out of compliance with debt covenants and will be unlikely to make debt repayments on their original schedule.

Grade 4: Investments in portfolio companies whose performance is materially below the Advisors expectations where business trends have deteriorated and risk factors have increased
substantially since the original investment. Investments graded 4 are those for which some loss of principal is expected.

The
Advisor monitors and, when appropriate, changes the investment ratings assigned to each investment in our portfolio. In connection with our valuation process, the Advisor and Board of Directors review these investment ratings on a quarterly basis.
Our average investment rating was 1.26 at March 31, 2011 versus 1.32 at December 31, 2010. The following is a distribution of the investment ratings of our portfolio companies at March 31, 2011 and December 31, 2010:

Results comparisons for the three months ended March 31, 2011 and 2010.

Investment income

Investment income totaled $25,160,129 and $27,799,099, respectively, for the three months ended March 31, 2011 and 2010, of which $12,521,315 and $14,994,235 were attributable to interest and fees on
senior secured loans, $11,696,393 and $11,998,827 to interest earned on other debt securities, $923,643 and $805,808 to dividends from preferred equity securities and $18,778 and $229 to interest earned on cash equivalents, respectively. The
decrease in investment income for the current period was primarily due to a lower average debt portfolio yield as compared to the prior period. In addition, the impact on investment income of net new investment activity in the current quarter was
nominal as such activity was concentrated near quarter-end.

Expenses

Expenses for the three months ended March 31, 2011 and 2010 were $10,283,494 and $7,533,834, respectively, which consisted of
$4,465,239 and $4,322,471 in base management fees, zero and $493,951 in incentive management fees, $3,642,219 and $1,122,254 in interest expense and fees related to the Credit Facility, $608,727 and $168,292 in amortization of debt issuance costs,
$425,485 and $398,664 in Advisor expenses, $359,056 and $203,266 in professional fees, $290,802 and $257,723 in administrative services, $120,725 and $152,408 in insurance expenses, $108,269 and $95,837 in director fees and $262,972 and $318,968 in
other expenses, respectively. The increase in base management fees reflects an increase in the quarterly portfolio values on which the fees are paid (in arrears). The increase in interest expense and fees related to the Credit Facility primarily
reflect the issuance of our Senior Secured Notes in January 2011.

Net investment income

Net investment income was $14,876,635 and $20,265,265 for the three months ended March 31, 2011 and 2010, respectively. The decrease
is primarily a result of a decline in interest income, as well as an increase in interest and Credit Facility related expenses.

Net realized gain or loss

Net realized loss of $(42,867,692) for the three months ended March 31, 2011 was the result of $(42,367,616) in net losses realized from the disposition of our investments and $(500,076) in net loss
realized on foreign currency

transactions. Net realized loss on investments for the three months ended March 31, 2011 resulted primarily from the restructuring or disposition of our investments in Facet Technologies,
LLC and Mattress Giant Corporation. Nearly the entire net realized loss on investments represents amounts that had been reflected in unrealized depreciation on investments in prior periods. Foreign currency gains and losses are attributable to
forward currency contracts used to mitigate the impact that changes in foreign exchange rates would have on our investments denominated in foreign currencies. For the three months ended March 31, 2010, net realized loss was $(42,363,323), which
was comprised of $(42,915,060) in net losses realized from the disposition or restructuring of our investments and $551,737 in net gains realized on foreign currency transactions.

Net unrealized appreciation or depreciation

For the three months ended March 31, 2011 and 2010, the change in net unrealized appreciation was a decrease in net unrealized appreciation of $46,005,949 and $52,581,109, respectively. The decrease
in net unrealized appreciation for the three months ended March 31, 2011 was comprised of a decrease in net unrealized appreciation on investments of $46,289,424 and a net unrealized foreign currency translation loss of $(283,475). The decrease
in net unrealized depreciation was a result of the investment restructurings and dispositions described above and improved capital market conditions. The valuations of our investments were favorably impacted by improved performance in certain
portfolio companies and market-wide decreases in interest yields, as well as increased multiples used to estimate the fair value of some of our investments. Market-wide movements and trading multiples are not necessarily indicative of any
fundamental change in the condition or prospects of our portfolio companies. The decrease in net unrealized depreciation for the three months ended March 31, 2010 was comprised of a decrease in net unrealized depreciation on investments of
$54,045,037 and a net unrealized foreign currency translation loss of $(1,463,928).

Net increase or decrease in net assets
resulting from operations

The net increase or decrease in net assets resulting from operations for the three months ended
March 31, 2011 and 2010 was an increase of $18,014,892 and $30,483,051, respectively. The lower net increase in net assets from operations primarily reflects the decrease in net investment income and net realized and unrealized gain for the
three months ended March 31, 2011.

Supplemental information

We report our financial results on a GAAP basis; however, management believes that evaluating our ongoing operating results may be
enhanced if investors have additional non-GAAP basis financial measures. Management reviews non-GAAP financial measures to assess ongoing operations and, for the reasons described below, considers them to be effective indicators, for both management
and investors, of our financial performance over time. Management does not advocate that investors consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

We record our liability for Incentive Fees as we become legally obligated to pay them, based on a hypothetical liquidation at
the end of each reporting period. Our obligation to pay Incentive Fees with respect to any fiscal quarter is based on a formula that reflects our results over a trailing four-fiscal quarter period ending with the current fiscal quarter. We are
legally obligated to pay the amount resulting from the formula less any cash payments of Incentive Fees during the prior three quarters. The formulas requirement to reduce the Incentive Fees by amounts paid with respect to Incentive Fees in
the prior three quarters has caused our Incentive Fees expense to become, and currently is expected to be, concentrated in the fourth quarter of each year. Management believes that reflecting Incentive Fees throughout the year, as the related
investment income is earned, is an effective measure of our profitability and financial performance that facilitates comparison of current results with historical results and with those of our peers. Our as adjusted results reflect
Incentive Fees based on the formula we utilize for each trailing four-fiscal quarter period, with the formula applied to the current quarters incremental earnings and without any reduction for Incentive Fees paid during the prior three
quarters. The resulting amount represents an upper limit of each quarters incremental Incentive Fees that we may become legally obligated to pay at the end of the year. Prior year amounts are estimated in the same manner. These estimates
represent upper limits because, in any calendar year, subsequent quarters investment underperformance could reduce the Incentive Fees payable with respect to prior quarters operating results. Changes in the economic environment,
financial markets and other parameters used in determining such estimates could cause actual results to differ and such differences could be material. See Note 3 to the financial statements in this Quarterly Report for a more detailed description of
the Companys incentive management fee.

Financial
condition, liquidity and capital resources

During the three months ended March 31, 2011, we generated operating
cash flows primarily from interest earned and fees received on senior secured loans and other debt securities, as well as from sales and unsettled purchases of selected portfolio company investments or repayments of principal.

Net cash used in operating activities during the three months ended March 31, 2011 was $30,141,071. Our primary source of cash from
operating activities during the period was a net increase in net assets from operations of $18,014,892, which was more than offset by purchases of investments in portfolio companies (net of sales and repayments) of $35,504,672.

Net cash provided by financing activities during the three months ended March 31, 2011 was $82,379,224. Our primary source of cash for
financing activities was $175,000,000 in proceeds from the issuance of our Senior Secured Notes in January. Our primary uses of cash for financing activities were $20,927,156 of dividend distributions and $70,000,000 of net repayments under our
Credit Facility.

Our senior secured, multi-currency Credit Facility provides us with $375,000,000 in total availability,
consisting of $275,000,000 of revolving loan commitments and $100,000,000 of term loan commitments. The Credit Facility is secured by substantially all of the assets in our portfolio, including cash and cash equivalents. The Credit Facility has a
stated maturity date of December 6, 2013 and the interest rate applicable to borrowings thereunder is generally LIBOR plus an applicable spread of either 3.00% or 3.25% for revolving loans, based on a pricing grid depending on the
Companys credit rating, and LIBOR plus 3.00% for term loans. The Credit Facility does not contain a LIBOR floor requirement. At March 31, 2011, the effective LIBOR spread under the Credit Facility was 3.00%. Term loan commitments under
the Credit Facility have been fully drawn and, once repaid, may not be reborrowed. The Credit Facility also includes an accordion feature that allows the Company, under certain circumstances, to increase the size of the Credit Facility
by up to an additional $275,000,000 of revolving loan commitments and $250,000,000 of term loan commitments. The Credit Facility is used to supplement the Companys equity capital to make additional portfolio investments and for other general
corporate purposes. At March 31, 2011, we had $100,000,000 drawn and outstanding under the Credit Facility, with $275,000,000 available to us, subject to compliance with customary affirmative and negative covenants, including the maintenance of
a minimum stockholders equity, the maintenance of a ratio of not less than 200% of total assets (less total liabilities other than indebtedness) to total indebtedness, and restrictions on certain payments and issuance of debt. In addition,
borrowings under the Credit Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that applies different advance rates to different types of assets in the Companys portfolio.

On January 18, 2011, the Company closed a private placement issuance of $158,000,000 in aggregate principal amount of Senior Secured
Notes with a fixed interest rate of 6.50% and a maturity date of January 18, 2016 and $17,000,000 million in aggregate principal amount of Senior Secured Notes with a fixed interest rate of 6.60% and a maturity date of January 18, 2018.

##### Table of Contents

Interest on the Senior Secured Notes is due semi-annually on January 18 and July 18, commencing on July 18, 2011. The proceeds from the issuance of the Senior Secured Notes were
used to fund new portfolio investments, reduce outstanding borrowings under the Credit Facility and for general corporate purposes. The Senior Secured Notes contain customary affirmative and negative covenants substantially similar to those in our
Credit Facility. At March 31, 2011, we were in compliance with all financial and operational covenants required by the Credit Facility and Senior Secured Notes.

At March 31, 2011, we had $54,380,894 in cash and cash equivalents.

The
primary use of existing funds is expected to be purchases of investments in portfolio companies, cash distributions to our stockholders, repayment of indebtedness and other general corporate purposes.

Our shelf registration permits us to offer, from time to time, up to approximately $830 million of our common stock, preferred stock,
debt securities, warrants representing rights to purchase shares of our common stock, preferred stock or debt securities and subscription rights. As a closed-end investment company regulated as a BDC under the 1940 Act, we are prohibited from
selling shares of our common stock at a price below the current net asset value of the stock, or NAV, unless our stockholders approve such a sale and our Board of Directors makes certain determinations.

Off-balance sheet arrangements

In the normal course of business, the Company may enter into guarantees on behalf of portfolio companies. Under these arrangements, the Company would be required to make payments to third parties if the
portfolio companies were to default on their related payment obligations. The Company has no such guarantees outstanding at March 31, 2011. The Companys only such guarantee outstanding at December 31, 2010 was terminated on January 17, 2011
with no payments having been made thereunder.

Dividends

Our quarterly dividends, if any, are determined by our Board of Directors. Dividends are declared considering our estimate of annual
taxable income available for distribution to stockholders and the amount of taxable income carried over from the prior year for distribution in the current year. We cannot assure stockholders that they will receive any dividends and distributions at
all or dividends and distributions at a particular level. Dividends declared by the Company since July 25, 2005 (inception of operations) have been as follows:

Tax characteristics of all
dividends are reported to stockholders on Form 1099 after the end of the calendar year.

We have qualified and elected and
intend to continue to qualify for the tax treatment applicable to regulated investment companies under Subchapter M of the Code, and, among other things, have made and intend to continue to make the requisite distributions to our stockholders which
will relieve us from federal income taxes. Therefore, no provision has been recorded for federal income taxes. We may, at our discretion, carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on this income.
We will accrue excise tax on estimated undistributed taxable income as required.

In order to qualify for favorable tax
treatment as a RIC, we are required to distribute annually to our stockholders at least 90% of investment company taxable income, as defined by the Code. To avoid federal excise taxes, we must distribute annually at least 98% of our income (both
ordinary income and net capital gains).

A portion of amounts we have paid or will pay as dividends to stockholders during
2011 may consist of taxable income carried forward from the prior year. Taxable income carried forward from the prior year to 2011 totaled approximately $8,900,000 or $0.12 per share.

We maintain an opt out dividend reinvestment plan for our common stockholders. As a result, except as discussed below, if we
declare a dividend, stockholders cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically opt out of the dividend reinvestment plan so as to receive cash dividends. With
respect to our dividends and distributions paid to stockholders during the three months ended March 31, 2011 and 2010, dividends reinvested pursuant to our dividend reinvestment plan totaled $2,295,131 and $1,020,149, respectively.

Under the terms of our amended and restated dividend reinvestment plan adopted on March 4, 2009, dividends may be paid in newly
issued or treasury shares of our common stock at a price equal to 95% of the market price on the dividend payment date. This feature of the plan means that, under certain circumstances, we may issue shares of our common stock at a price below net
asset value per share, which could cause our stockholders to experience dilution.

Income we receive from origination,
structuring, closing, commitment and other upfront fees associated with investments in portfolio companies is treated as taxable income when received and accordingly, distributed to stockholders. For the three months ended March 31, 2011 and
2010, these fees totaled zero and $27,500. For financial reporting purposes, such fees are recorded as unearned income and accreted/amortized over the life of the respective investment. We anticipate earning additional upfront fees in the future and
such fees may cause our taxable income to exceed our GAAP income, although the differences are expected to be temporary in nature.

In order to satisfy the annual distribution requirement applicable to RICs, we have the ability to declare a large portion of a dividend in shares of our common stock instead of in cash. As long as a
sufficient portion of such dividend is paid in cash (which portion can be as low as 10% for our taxable years ending prior to 2012) and certain requirements are met, the entire distribution would be treated as a taxable dividend for U.S. federal
income tax purposes.

Recent developments

On May 9, 2011, our Board of Directors declared a dividend of $0.26 per share, payable on July 1, 2011 to stockholders of record
at the close of business on June 17, 2011.

Notice is hereby given in accordance with Section 23 of the 1940 Act
that from time to time we may purchase shares of our common stock in the open market at prevailing market prices.

|Item 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

We are subject to financial market risks, including changes in interest rates. At March 31, 2011, 47% of our debt investments bore interest based on floating rates, such as LIBOR, the Federal Funds
Rate or the Prime Rate. The interest rates on such investments generally reset by reference to the current market index after one to six months. At March 31, 2011, the percentage of our total debt investments that bore floating rate interest
based on an interest rate floor was 28%. Floating rate investments subject to a floor generally reset by reference to the current market index after one to six months only if the index exceeds the floor.

To illustrate the potential impact of changes in interest rates, we have performed the following analysis based on our March 31,
2011 balance sheet and assuming no changes in our investment structure. Net asset value is analyzed using the assumptions that interest rates, as defined by the LIBOR and U.S. Treasury yield curves, increase or decrease and that the yield curves of
the rate shocks will be parallel to each other. Under this analysis, an instantaneous 100 basis point increase in LIBOR and U.S. Treasury yields would cause a decline of approximately $8,500,000, or $0.12 per share, in the value of our net assets at
March 31, 2011 and a corresponding 100 basis point decrease in LIBOR and U.S. Treasury yields would cause an increase of approximately $7,900,000, or $0.11 per share, in the value of our net assets on that date.

While hedging activities may help to insulate us against adverse changes in interest rates, they also may limit our ability to
participate in the benefits of lower interest rates with respect to our portfolio of investments. During the three months ended March 31, 2011 and 2010, we did not engage in any interest rate hedging activity.



|Item 4. | Controls and Procedures
|------- | -----------------------

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our
management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 under the Securities Exchange Act of 1934). Based on
that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our current disclosure controls and procedures are effective in timely alerting them to material information relating to us that is required to be disclosed
by us in the reports we file or submit under the Securities Exchange Act of 1934.

There have been no changes in our internal
control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION



|Item 1. | Legal Proceedings
|------- | -----------------

From
time to time, we and the Advisor may be a party to certain legal proceedings incidental to the normal course of our business, including the enforcement of our rights under contracts with our portfolio companies. While we cannot predict the outcome
of these legal proceedings with certainty, we do not expect that these proceedings will have a material effect on our financial statements.



|Item 1A. | Risk Factors
|-------- | ------------

There have
been no material changes from the risk factors previously disclosed in our most recent Form 10-K filing.



|Item 2. | Unregistered Sales of Equity Securities and Use of Proceeds
|------- | -----------------------------------------------------------

Sales of unregistered securities

On March 16, 2011 we issued
and sold to the Advisor in a private placement 200,000 shares of our common stock for aggregate proceeds of $2,000,000, which were used for general corporate purposes. This placement was exempt from the registration requirements of the Securities
Act pursuant to Section 4(2) of the Securities Act.

|In 2008, our Board of Directors
approved a share repurchase plan under which we may repurchase up to 2.5 percent of our outstanding shares of common stock from time to time in open market or privately negotiated transactions. In 2009, our Board of Directors approved an extension
and increase to the share repurchase plan which authorized us to repurchase up to an additional 2.5 percent of our outstanding shares of common stock from time to time. In May 2011, the repurchase plan was further extended through the earlier of
June 30, 2012 or until the approved number of shares has been repurchased. After giving effect to the Boards most recent action, the total number of additional shares authorized for repurchase is 1,594,971. The repurchase plan does not
obligate us to acquire any specific number of shares and may be discontinued at any time. We intend to fund any repurchases with available cash.
