CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained herein constitute "forward-looking statements"
within the meaning of the Private Securities Litigation Reform Act of 1995 with
respect to future financial or business performance, strategies or expectations.
Forward-looking statements are typically identified by words or phrases such as
"trend," "opportunity," "pipeline," "believe," "comfortable," "expect,"
"anticipate," "current," "intention," "estimate," "position," "assume,"
"potential," "outlook," "continue," "remain," "maintain," "sustain," "seek,"
"achieve" and similar expressions, or future or conditional verbs such as
"will," "would," "should," "could," "may" or similar expressions. BlackRock
Kelso Capital Corporation (the "Company") cautions that forward-looking
statements are subject to numerous assumptions, risks and uncertainties, which
change over time. Forward-looking statements speak only as of the date they are
made, and the Company assumes no duty to and does not undertake to update
forward-looking statements. Actual results could differ materially from those
anticipated in forward-looking statements and future results could differ
materially from historical performance.

In addition to factors previously disclosed in the Company's Securities and
Exchange Commission (the "SEC") reports and those identified elsewhere in this
report, the following factors, among others, could cause actual results to
differ materially from forward-looking statements or historical performance:

     (1)  the introduction, withdrawal, success and timing of business
          initiatives and strategies;
     (2)  changes in political, economic or industry conditions, the interest
          rate environment or financial and capital markets, which could result
          in changes in the value of the Company's assets;
     (3)  the relative and absolute investment performance and operations of the
          Company's investment adviser, BlackRock Kelso Capital Advisors LLC
          (the "Investment Advisor");
     (4)  the impact of increased competition;
     (5)  the impact of future acquisitions and divestitures;
     (6)  the unfavorable resolution of legal proceedings;
     (7)  the extent and timing of any share repurchases;
     (8)  the impact, extent and timing of technological changes and the
          adequacy of intellectual property protection;
     (9)  the impact of legislative and regulatory actions and reforms and
          regulatory, supervisory or enforcement actions of government agencies
          relating to the Company or the Investment Advisor;
     (10) terrorist activities, which may adversely affect the general economy,
          real estate, financial and capital markets, specific industries, and
          the Company and the Investment Advisor;
     (11) the ability of the Investment Advisor to attract and retain highly
          talented professionals;
     (12) fluctuations in foreign currency exchange rates; and
     (13) the impact of changes to tax legislation and, generally, the tax
          position of the Company.

                       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 filed an election to be treated 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, or 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
intends to invest 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 (the "Offering") of
35,366,589 shares of its common stock, par value $.001 per share (the "Common
Stock"), at a price of $15.00 per share. Net proceeds from the Offering of
$529,333,799 reflect the payment of a placement fee of $507,407 and legal fees
and other offering costs of $657,639.

The accompanying interim 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 necessarily 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, 2005, which was filed with the Securities and Exchange Commission on March
29, 2006.

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, which are generally obtained from an independent
     pricing service or one or more broker-dealers or market makers. However,
     debt investments with remaining maturities within 60 days are valued at
     cost plus accreted discount, or minus amortized premium, which approximates
     fair value. Debt and equity securities for which market quotations are not
     readily available 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
     many of the investments in its portfolio, the Company expects to value many
     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 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
     the differences could be material.

                       BLACKROCK KELSO CAPITAL CORPORATION
              NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (Continued)

With respect to the Company's investments for which market quotations are not
readily available, the Board of Directors undertakes a multi-step valuation
process each quarter, as described below:

     (1)  The quarterly valuation process begins with each portfolio company or
          investment being initially valued by the investment professionals of
          BlackRock Kelso Capital Advisors LLC, the Company's investment adviser
          (the "Investment Advisor"), responsible for the portfolio investment;

     (2)  Preliminary valuation conclusions are then documented and discussed
          with senior management;

     (3)  To the extent determined by the Audit Committee of the Board of
          Directors, independent valuation firms engaged by the Board of
          Directors conduct independent appraisals and review management's
          preliminary valuations and their own independent assessment;

     (4)  The Audit Committee of the Board of Directors reviews the preliminary
          valuations of the investment ( professionals, senior management and
          independent valuation firms; and

     (5)  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 Investment Advisor, the respective independent valuation
          firms and the Audit Committee.

The types of factors that the Company may take into account in fair value
pricing its investments include, as relevant, the nature and realizable value of
any collateral, the portfolio company's ability to make payments and its
earnings and discounted cash flow, the markets in which the portfolio company
does business, comparison to publicly traded securities and other relevant
factors.

Determination of fair values involves subjective judgments and estimates.
Accordingly, these notes to the financial statements express the uncertainty
with respect to the possible effect of such valuations, and any change in such
valuations, on the financial statements.

The carrying value of the Company's financial instruments approximate fair
value. The carrying value of receivables, other assets, accounts payable and
accrued expenses approximate fair value due to their short maturity.

None of the Company's portfolio companies are controlled by or affiliated with
the Company as defined in the 1940 Act.

(b)  Cash equivalents include short-term investments in money market instruments
     with remaining maturities when purchased of three months or less.

(c)  Security transactions are accounted for on the trade date unless there are
     substantial conditions to the purchase.

(d)  Gains or losses on the sale of investments are calculated using the
     specific identification method.

(e)  Interest income, adjusted for amortization of premium and accretion of
     discount, is recorded on an accrual basis. Interest income is not accrued
     if collection is deemed doubtful or the related investment is in default.
     For loans and debt securities with contractual payment-in-kind ("PIK")
     interest, which represents contractual interest accrued and added to the
     loan balance and which generally becomes due at maturity, PIK interest is
     not accrued if the portfolio company valuation indicates that the PIK
     interest is not collectible. Origination, structuring, closing, commitment

(f)  Organizational costs of the Company were expensed as incurred. Offering
     costs were charged against paid-in capital.

(g)  The Company has qualified and elected and intends to continue to qualify
     for the tax treatment applicable to regulated investment companies under
     Subchapter M of the Code, and, among other things, has made and intends to
     continue to make the requisite distributions to its shareholders which will
     relieve the Company from federal income and excise taxes. Therefore, no
     provision has been recorded for federal income or excise taxes.

     In order to qualify as a RIC, the Company is required to distribute
     annually to its shareholders at least 90% of 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).

     In accordance with GAAP, book and tax basis differences relating to
     distributions to shareholders and other permanent book and tax differences
     are reclassified to capital in excess of par. In addition, the character of
     income and gains to be distributed is determined in accordance with income
     tax regulations that may differ from GAAP.

(h)  Dividends and distributions to common shareholders are recorded on the
     ex-date. The amount to be paid out as a dividend is determined by the Board
     of Directors. Recent dividends declared by the Company were as follows:

     The Company has adopted a dividend reinvestment plan that provides for
     reinvestment of distributions on behalf of shareholders, unless a
     shareholder elects to receive cash. As a result, if the Board of Directors
     authorizes, and the Company declares, a cash dividend, then shareholders
     who have not "opted out" of the dividend reinvestment plan will have their
     cash dividends automatically reinvested in additional shares of Common
     Stock, rather than receiving the cash dividends.

(i)  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. Risks may arise as a result of the potential
     inability of the counterparties to meet the terms of their contract.

     Details of the open forward foreign currency contract at September 30, 2006
     were as follows.

     There were no open forward foreign currency contracts at December 31, 2005.


(j)  Foreign currency amounts are translated into United States dollars on the
     following basis:


     (1)  market value of investment securities, other assets and liabilities --
          at the spot exchange rate on the last business day of each month; and

     (2)  purchases and sales of investment securities, income and expenses --
          at the rates of exchange prevailing on the respective dates of such
          transactions.

     The Company isolates that portion of the results of operations arising as a
     result of changes in the foreign exchange rates from the fluctuations
     arising from changes in the market prices of investments held at period
     end. Similarly, the Company isolates the effect of changes in foreign
     exchange rates from the fluctuations arising from changes in the market
     prices of portfolio investments sold during the period.

     Investments denominated in foreign currencies and foreign currency
     transactions may involve certain considerations and risks not typically
     associated with those of domestic origin, including unanticipated movements
     in the value of the foreign currency relative to the U.S. dollar.

(k)  Recently Issued Accounting Pronouncements:

     In July 2006, the Financial Accounting Standards Board ("FASB") issued FASB
     Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an
     interpretation of FASB Statement No. 109 ("FIN 48"), which clarifies the
     accounting for uncertainty in tax positions. FIN 48 requires that the
     Company recognize in its financial statements the impact of a tax position,
     and if that position is more likely than not of being sustained on audit,
     based on the technical merits of the position. The provisions of FIN 48 are
     effective for fiscal years beginning after December 15, 2006, with the
     cumulative effect of the change in accounting principle recorded as an
     adjustment to opening retained earnings. The Company is currently
     evaluating the impact of adopting FIN 48 on its financial statements. At
     this time, the impact to the Company's financial statements has not been
     determined.

     In September 2006, the FASB issued Statement of Financial Accounting
     Standards No. 157, Fair Value Measurements ("SFAS 157"), which defines fair
     value, establishes a framework for measuring fair value, and expands
     disclosures about fair value measurements. The provisions of SFAS 157 are
     effective for fiscal years beginning after November 15, 2007. The Company
     is currently evaluating the impact of adopting SFAS 157 on its financial
     statements. At this time, the impact to the Company's financial statements
     has not been determined.

3.   Agreements and Related Party Transaction

The Company has entered into an Investment Management Agreement (the "Management
Agreement") with the Investment Advisor, under which the Investment 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 Investment Advisor receives a base
management fee (the "Management Fee") from the Company at an annual rate of 2.0%
of the Company's total assets, including any assets acquired with the proceeds
of leverage. For services rendered under the Management Agreement during the
period commencing from July 25, 2005, the closing of the Offering (the
"Closing"), through and including the first twelve months of operations, the
Management Fee will be payable monthly in arrears. For services rendered under
the Management Agreement after that time, the Management Fee will be paid
quarterly in arrears.

The Investment Advisor has contractually agreed to waive its rights to receive
one-half of the amount of the Management Fee the Investment Advisor would
otherwise be entitled to receive from the Company until the first date on which
90% of the assets of the Company are invested in portfolio companies in
accordance with the Company's investment objective, excluding investments in
cash, cash equivalents, U.S. government securities and other high-quality debt
investments that mature in one year or less from the date of investment, or the
first anniversary of the Closing, whichever is sooner (the "Ramp-Up Date").
Thereafter, the Investment Advisor has agreed to waive, until such time as the
Company has completed an initial public offering of its Common Stock and listed
its Common Stock on a national securities exchange (collectively, the "Public
Market Event"), one-quarter of the amount of the Management Fee the Investment
Advisor would otherwise be entitled to receive from the Company. In addition,
the Investment Advisor has agreed to (a) waive Management Fees for any calendar
year in excess of approximately $11.9 million until the earlier of (i) such time
as the Company has completed the Public Market Event or (ii) the fourth
anniversary of the Company's inception of operations and (b) waive Management
Fees in excess of approximately $5.6 million during the fifth year of the
Company's operations unless the Company has completed the Public Market Event.

                       BLACKROCK KELSO CAPITAL CORPORATION
              NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (Continued)

For the three and nine months ended September 30, 2006 and for the period July
25, 2005 (inception of operations) to September 30, 2005, the Investment Advisor
earned $1,923,437, $4,622,971 and $988,170, respectively, in base management
fees, net of the waiver provision, from the Company.

The Management Agreement provides that the Investment Advisor or its affiliates
may be entitled to an incentive management fee (the "Carried Interest") under
certain circumstances. The determination of the Carried Interest, as described
in more detail below, will result in the Investment Advisor or its affiliates
receiving no Carried Interest payments if returns to Company shareholders, as
described in more detail below, do not meet an 8.0% annualized rate of return
and will result in the Investment Advisor or its affiliates receiving less than
the full amount of the Carried Interest percentage until returns to shareholders
exceed an approximate 13.3% annualized rate of return. The determination of the
Carried Interest is subject to any applicable limitations under the 1940 Act and
the Investment Advisors Act of 1940.

Commencing on the Ramp-Up Date, the Company will pay to the Investment Advisor
or its affiliates at the same time as, and not in advance of, any distributions
in respect of the Company's Common Stock, (i) 50% of the amount by which the
cumulative distributions and amounts distributable to the holders of the Common
Stock of the Company exceed an 8% annualized rate of return on net asset value
on the Ramp-Up Date until the Investment Advisor or its affiliates have received
from the Company an amount equal to 20% of the sum of the cumulative amounts
distributed in accordance with the Management Agreement and the cumulative
amounts of net income (including realized capital gains in excess of realized
capital losses) in excess of net unrealized capital depreciation distributed to
the holders of the Company's Common Stock, and (ii) thereafter an amount equal
to 20% of the sum of the amount distributed in accordance with the Management
Agreement and the cumulative amounts of net income (including realized capital
gains in excess of realized capital losses) in excess of net unrealized capital
depreciation distributed to the holders of the Company's Common Stock. After the
Public Market Event, if any, the amounts above will be measured and paid
quarterly on a rolling four-quarter basis and will take into account any
decrease in net unrealized depreciation during the measurement period to the
extent such decrease did not exceed the net amount of capital depreciation at
the beginning of such period and does not exceed the excess of cumulative
realized capital gains over cumulative realized capital losses.

For the period July 25, 2006 (Ramp-Up Date) through September 30, 2006, the
Investment Advisor earned $1,309,382 in incentive management fees, or Carried
Interest, from the Company. No incentive management fees were earned prior to
the Ramp-Up Date.

The Management Agreement provides that the Company will reimburse the Investment
Advisor for costs and expenses incurred by the Investment Advisor for office
space rental, office equipment and utilities allocable to the performance by the
Investment Advisor of its duties under the Management Agreement, as well as any
costs and expenses incurred by the Investment Advisor relating to any
non-investment advisory, administrative or operating services provided by the
Investment Advisor to the Company. For the three and nine months ended September
30, 2006 and for the period July 25, 2005 (inception of operations) to September
30, 2005, the Company incurred $200,994, $482,130 and $132,616, respectively,
for costs and expenses reimbursable to the Investment Advisor under the
Management Agreement.

No person who is an officer, director or employee of the Investment 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 Investment
Advisor receive compensation for their services and reimbursement of expenses
incurred to attend meetings.

The Company has also 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. The PNC Financial Services
Group, Inc. ("PNC") is a significant shareholder of the ultimate parent of the
Administrator.

For the three and nine months ended September 30, 2006 and for the period July
25, 2005 (inception of operations) to September 30, 2005, the Company incurred
$252,054, $747,945 and $185,484, respectively, for administrative services
expenses payable to the Administrator under the Administration Agreement.

              NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (Continued)

From time to time, the Investment Advisor or the Administrator may pay amounts
owed by the Company to third party providers of goods or services. The Company
will subsequently reimburse the Investment Advisor or the Administrator, as the
case may be, for such amounts paid on its behalf. Reimbursements to the
Investment Advisor for the three and nine months ended September 30, 2006 and
for the period July 25, 2005 (inception of operations) to September 30, 2005
were $231,124, $663,377 and $0, respectively. Reimbursements to the
Administrator for the three and nine months ended September 30, 2006 and for the
period July 25, 2005 (inception of operations) to September 30, 2005, were
$3,614, $31,107 and $180,910, respectively. An additional $1,857 and $10,935 in
reimbursements were payable to the Investment Advisor at September 30, 2006 and
December 31, 2005, respectively.

PFPC Inc. ("PFPC"), a subsidiary of PNC, provides administrative and accounting
services to the Company pursuant to a Sub-Administration and Accounting Services
Agreement. PFPC Trust Company, another subsidiary of PNC, provides custodian
services to the Company pursuant to a Custodian Services Agreement. Also, PFPC
provides transfer agency and compliance support services to the Company pursuant
to a Transfer Agency Agreement and a Compliance Support Services Agreement,
respectively. For the services provided to the Company by PFPC and its
affiliates, PFPC is entitled to an annual fee of 0.02% of the Company's average
net assets plus reimbursement of reasonable expenses, and a base fee, payable
monthly. PFPC Trust Company may charge the Company additional fees for cash
overdraft balances or for sweeping excess cash balances.

For the three months and nine months ended September 30, 2006 and for the period
July 25, 2005 (inception of operations) to September 30, 2005, the Company
incurred $52,996, $158,340 and $33,450, respectively, for administrative,
accounting, custodian and transfer agency services fees payable to PFPC and its
affiliates under the related agreements.

On July 25, 2005, in connection with the closing of the Offering, the Company
issued approximately 33,333,333 shares of its Common Stock to BlackRock Kelso
Capital Holding LLC, an entity for which the Investment Advisor serves as
manager, in exchange for total consideration of $500,000,000 ($15.00 per share),
consisting of $80,282,060 in cash and a portfolio of short-term investments and
cash equivalents valued at $419,717,940. The transaction was effected in
accordance with the Company's valuation procedures governing securities
transactions with affiliates and was ratified by the Board of Directors.

On March 8, 2006, the Company's Board of Directors authorized the issuance and
sale from time to time of up to $2,500,000 in aggregate net asset value of
shares of the Company's Common Stock to certain existing and future employees of
the Investment Advisor at a price per share equal to the greater of $15.00 or
the Company's most recently determined net asset value per share at the time of
sale. Pursuant to this authorization, on April 1, 2006 the Company issued and
sold in a private placement 54,000 shares of Common Stock for aggregate proceeds
of $810,000 to certain employees of the Investment Advisor. On August 10, 2006,
the Company's Board of Directors authorized the issuance and sale from time to
time of an unlimited number of shares of the Company's Common Stock to the
Investment Advisor at a price per share equal to the Company's most recently
determined net asset value per share at the time of sale, such shares to be used
by the Advisor for employee compensation purposes. Sales under both of the
foregoing authorizations are expected to be exempt from the registration
requirements of the Securities Act of 1933.

At September 30, 2006, the Investment Advisor beneficially owned indirectly
approximately 775,000 shares of the Company's Common Stock, representing
approximately 2.1% of the total shares outstanding. At September 30, 2006, other
entities affiliated with the Administrator and/or PFPC beneficially owned
indirectly approximately 2,475,000 shares of the Company's Common Stock,
representing approximately 6.6% of the total shares outstanding. These
percentages of total shares outstanding did not change appreciably from December
31, 2005. At September 30, 2006 and December 31, 2005, an entity affiliated with
the Administrator owned 36.5% of the members' interests of the Investment
Advisor.

On September 29, 2006, Merrill Lynch & Co., Inc. ("Merrill Lynch") contributed
its investment management business, Merrill Lynch Investment Managers ("MLIM"),
to BlackRock, Inc. ("BlackRock"), the ultimate parent of the Company's
Administrator and of a significant holder of the members' interests of the
Investment Advisor, to form a new investment management company. The new company
operates under the BlackRock name and is governed by a board of directors with a
majority of independent members. Merrill Lynch will own no more than 49.8% of
the capital stock of the new company on a fully diluted basis and no more than
45% on an undiluted basis. PNC owns approximately

The Company earned $132,101 and $335,362 in interest income on investments in
money market securities issued by MLIM or its former affiliates for the three
and nine months ended September 30, 2006, respectively, and $66,670 for the
period July 25, 2005 (inception of operations) to September 30, 2005. The
Company held no investments in securities issued by MLIM or its former
affiliates at September 30, 2006. From time to time, former affiliates of MLIM
may serve as broker/dealer or agent for the Company or for portfolio companies
in which the Company invests. For the period July 25, 2005 (inception of
operations) to September 30, 2006, the Company did not make any payments to
former MLIM affiliates for such services.

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

5.   Purchases and Sales/Repayments of Investments

Excluding short-term investments, the Company's purchases and sales/repayments
of investments for the three months ended September 30, 2006 totaled
$190,897,536 and $33,357,245, respectively, and for the nine months ended
September 30, 2006 totaled $451,805,780 and $68,720,921, respectively.

6.   Commitments and Contingencies

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.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

The information contained in this section should be read in conjunction with the
financial statements and notes thereto appearing elsewhere in this report.

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 U.S. middle-market companies.

                                       23
<PAGE>


We are externally managed and have elected to be treated 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 U.S. companies, cash, cash
equivalents, U.S. government securities and high-quality debt investments that
mature in one year or less.

On July 25, 2005, we completed the Offering of 35,366,589 shares of our Common
Stock at a price of $15.00 per share, less a placement fee of $507,407 and legal
fees and other offering costs of $657,639. We received approximately $529.3
million in net proceeds from the Offering.

We have qualified and elected to be treated as a regulated investment company,
or a RIC, under Subchapter M of the Code. To continue to qualify as a RIC, we
must, among other things, continue to meet certain source-of-income and asset
diversification requirements. Pursuant to these elections, we generally have not
had and will not have to pay corporate-level taxes on any income that we
distribute to our shareholders.

Portfolio and Investment Activity

We closed a substantial number of new and diverse investments in portfolio
companies during the third quarter of 2006, a result of our Investment Advisor's
investment platform and favorable market conditions. During the quarter, we
invested approximately $190.9 million across 11 new and 3 existing portfolio
companies. The new investments consisted primarily of senior loans secured by
second liens ($101.9 million) and first liens ($27.9 million), subordinated
debt/corporate notes ($57.4 million) and equity securities ($3.7 million). For
the year-to-date period through September 30, 2006, we invested $451.8 million
across 25 new and 10 existing portfolio companies.

During the quarter, we received proceeds from sales/repayments of approximately
$33.4 million. For the year-to-date period through September 30, 2006, we
received proceeds from sales/repayments of approximately $68.7 million.

At September 30, 2006, our net portfolio (investments plus cash and cash
equivalents) of $571 million consisted of 40 portfolio companies and was
invested 80% in senior secured loans, 12% in subordinated debt/corporate notes,
1% in equity investments and 7% in short-term investments (including cash and
cash equivalents). Our average portfolio company investment by market value was
approximately $13 million. Our largest portfolio company investment by market
value was approximately $40 million and our five largest portfolio company
investments by market value comprised approximately 27% of our net assets at
September 30, 2006. At December 31, 2005, our net portfolio of $539 million
consisted of 26 portfolio companies and was invested 25% in senior secured
loans, 1% in subordinated debt/corporate notes, 1% in publicly traded, floating
rate closed-end funds, less than 1% in equity investments and 73% in short-term
investments (including cash and cash equivalents).

Our weighted average yield on invested capital excluding equity investments,
closed-end funds, short-term investments and cash equivalents was 12.0% at
September 30, 2006 versus 11.4% at June 30, 2006, 10.9% at March 31, 2006 and
10.7% at December 31, 2005. The weighted average yield on our invested capital
including equity investments, closed-end funds, short-term investments and cash
equivalents was 11.5% at September 30, 2006 versus 9.1% at June 30, 2006, 7.0%
at March 31, 2006 and 6.0% at December 31, 2005. Net of expenses, such yields
were 9.5% at September 30, 2006, compared with 7.6% at June 30, 2006, 5.5% at
March 31, 2006 and 4.4% at December 31, 2005. The weighted average yields on our
subordinated debt/corporate notes and senior secured loans were 14.1% and 11.7%,
respectively, at September 30, 2006 versus 12.8% and 11.5%, respectively, at
June 30, 2006, 10.7% and 10.9%, respectively, at March 31, 2006, and 10.3% and
10.8%, respectively, at December 31, 2005. Yields are computed using interest
rates and dividend yields as of the purchase date and include amortization of
loan origination and commitment fees, original issue discount and market premium
or discount, weighted by the value of the respective investment when averaged.

At September 30, 2006, 88% of our long-term investments bear interest based on
floating rates, such as LIBOR, EURIBOR, the Federal Funds Rate or the Prime
Rate, and 12% bear interest at fixed rates. At December 31, 2005, more than 98%
of our long-term investments bore interest based on floating rates.

Results of Operations

Operating Results for the Three Months Ended September 30, 2006 and the Period
Ended September 30, 2005

Operating results for the prior period July 25, 2005 (inception of operations)
to September 25, 2005 ("the period ended September 30, 2005") reflect our
initial period of operations, during which our portfolio was primarily invested
in cash equivalents and short-term investments.

Operating Income

Investment income totaled $15,116,450 and $3,599,086, respectively, for the
three months ended September 30, 2006 and the period ended September 30, 2005,
of which $12,565,057 and $22,916, respectively, were attributable to interest
and amortization of upfront fees on senior secured loans, $1,408,296 and
$3,542,146, respectively, to interest earned on short-term investments and cash
equivalents, $1,026,230 and $34,024, respectively, to interest earned on
subordinated debt/corporate notes, and $116,867 and $0, respectively, to
dividends from closed-end funds and preferred stock. As we continue to invest in
longer-term investments, we expect that we will generate additional income at
rates higher than those we received on our investments since our inception of
operations, although there can be no assurance that we will achieve this
objective.

Operating Expenses

Net operating expenses for the three months ended September 30, 2006 and the
period ended September 30, 2005 were $4,109,106 and $1,870,201, respectively,
consisting of $1,923,437 and $988,170, respectively, in base management fees
(net of management fee waiver of $895,428 and $988,170, respectively),
$1,309,382 and $0, respectively, in incentive management fees, or Carried
Interest, owed to the Investment Advisor, $295,260 and $216,708, respectively,

respectively, in other expenses.

Net Investment Income

Net investment income was $11,007,344 and $1,728,885, respectively, for the
three months ended September 30, 2006 and the period ended September 30, 2005.

Net Realized Gain

Net realized gain on investments of $139,801 for the three months ended
September 30, 2006 was the result of $430,880 in net gains realized from the
disposition of investments partially offset by $291,079 in net losses realized
on foreign currency transactions during the period. For the period ended
September 30, 2005, net realized gain on investments was $0.

Net Unrealized Appreciation

For the three months ended September 30, 2006 and the period ended September 30,
2005, the change in net unrealized appreciation was $264,329 and $69,360,
respectively, which was comprised of an increase in net unrealized appreciation
on investments of $150,051 and $116,865, respectively, an increase in net
unrealized depreciation on cash equivalents of $353 and $47,505, respectively,
and net unrealized appreciation on foreign currency translations of $114,631 and

Net Increase in Net Assets Resulting  from Operations

The net increase in net assets resulting from operations for the three months
ended September 30, 2006 and the period ended September 30, 2005 was $11,411,474
and $1,798,245, respectively.

Operating Results for the Nine Months Ended September 30, 2006

We commenced operations on July 25, 2005 and, therefore, have no period with
which to reasonably compare results for the nine months ended September 30,
2006.

Operating Income

Investment income totaled $35,994,494 for the nine months ended September 30,
2006, of which $24,951,251 was attributable to interest and amortization of
upfront fees on senior secured loans, $9,114,415 to interest earned on
short-term investments and cash equivalents, $1,376,492 to interest earned on
subordinated debt/corporate notes, $430,203 to dividends from closed-end funds
and preferred stock and $122,133 to other income. As we continue to invest in
longer-term investments, we expect that we will generate additional income at
rates higher than those we received on our investments since our inception of
operations, although there can be no assurance that we will achieve this
objective.

Operating Expenses

Net operating expenses for the nine months ended September 30, 2006 were
$8,309,735, consisting of $4,622,971 in base management fees (net of management
fee waiver of $3,595,228), $1,309,382 in incentive management fees, or Carried
Interest, owed to the Investment Advisor, $875,367 in administrative services
expenses, $531,223 in professional fees, $482,130 in Investment Advisor
expenses, $221,587 in director fees, $125,299 in insurance expenses, and

2006.

Net Realized Loss

Net realized loss on investments of $63,044 for the nine months ended September
30, 2006 was the result of $291,079 in net losses realized on foreign currency
transactions partially offset by $228,035 in net gains realized on the
disposition of investments during the period.

Net Unrealized Appreciation

For the nine months ended September 30, 2006, the change in net unrealized
appreciation was $2,081,264, which was comprised of an increase in net
unrealized appreciation on investments of $1,954,946, an increase in net
unrealized appreciation on cash equivalents of $11,687, and unrealized
appreciation on foreign currency translations of $114,631.

Net Increase in Net Assets Resulting  from Operations

The net increase in net assets resulting from operations for the nine months
ended September 30, 2006 was $29,702,979.

Financial Condition, Liquidity and Capital Resources

On July 25, 2005, we completed a private placement of 35,366,589 shares of our
Common Stock at a price of $15.00 per share. The net proceeds from the Offering
of $529,333,799 consisted of cash of $109,615,859 and a contribution of
short-term investments and cash equivalents of $419,717,940.

On March 8, 2006, our Board of Directors authorized the issuance and sale from
time to time of up to $2,500,000 in aggregate net asset value of shares of our
Common Stock to certain existing and future employees of the Investment Advisor
at a price per share equal to the greater of $15.00 or our most recently
determined net asset value per share at

                                       26
<PAGE>

the time of sale. Pursuant to this authorization, on April 1, 2006 we issued and
sold in a private placement 54,000 shares of Common Stock for aggregate proceeds
of $810,000 to certain employees of the Investment Advisor.

During the nine months ended September 30, 2006, we generated cash primarily
from cash flows from operations, including interest earned on senior secured
loans and subordinated debt/corporate notes, as well as from temporary
investments in cash equivalents and dividends received from closed-end fund
holdings. In the future, we may also fund a portion of our investments through
borrowings from banks and issuances of senior securities. As a business
development company, we are subject to regulations governing our operations that
affect our ability to raise additional capital. In the future, we may also
securitize a portion of our investments in senior secured loans or other assets.

At September 30, 2006, we had $11,004,790 in cash and cash equivalents and
$30,012,800 in other short-term investments that we intend to use in our
operations.

Our primary uses of funds are investments in portfolio companies, payment of
fees and other operating expenses and cash distributions to shareholders.

Our operating activities resulted in a net use of cash of $278,238,166 for the
nine months ended September 30, 2006, primarily due to net purchases of
investments.

Our financing activities resulted in the inflow of cash of $270,609 for the nine
months ended September 30, 2006, primarily due to proceeds from capital
subscriptions. In addition, our non-cash financing activities consisted of
$33,127,605 of dividend distributions reinvested.

Off-Balance Sheet Financing

At September 30, 2006, we had no off-balance sheet contractual obligations or
arrangements.

Dividends

We intend to distribute quarterly dividends to our shareholders. Our quarterly
dividends, if any, will be determined by our Board of Directors. Recent
dividends declared by the Company were as follows:

</TABLE>

We have qualified and elected to be taxed as a regulated investment company, or
RIC, under Subchapter M of the Code. To maintain our RIC status, we must
distribute annually at least 90% of our ordinary income and realized net
short-term capital gains in excess of realized net long-term capital losses, if
any, out of the assets legally available for distribution. In order to avoid
certain excise taxes imposed on RICs, we currently intend to distribute during
each calendar year an amount at least equal to the sum of (1) 98% of our
ordinary income for the calendar year, (2) 98% of our capital gains in excess of
capital losses for the one-year period ending on October 31st and (3) any
ordinary income and net capital gains for preceding years that were not
distributed during such years. In addition, although we currently intend to
distribute realized net capital gains (i.e., net long-term capital gains in
excess of short-term capital losses), if any, at least annually, out of the
assets legally available for such distributions, we may in the future decide to
retain such capital gains for investment.

We maintain an "opt out" dividend reinvestment plan for our common shareholders.
As a result, if we declare a dividend, shareholders' 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.

We may not be able to achieve operating results that will allow us to make
dividends and distributions at a specific level or to increase the amount of
these dividends and distributions from time to time. In addition, we may be
limited in our ability to make dividends and distributions due to the asset
coverage test for borrowings when applicable to us as a business development
company under the 1940 Act and due to provisions in future credit facilities. If
we do not

                                       27
<PAGE>

distribute a certain percentage of our income annually, we will suffer adverse
tax consequences, including possible loss of our status as a regulated
investment company. We cannot assure shareholders that they will receive any
dividends and distributions or dividends and distributions at a particular
level.

To the extent we perform substantial services in connection with investments in
portfolio companies, the associated income from origination, structuring,
closing, commitment and other upfront fees is treated as taxable income and
accordingly, distributed to shareholders as dividends. For the three and nine
months ended September 30, 2006, fees for such services totaled $1,636,982 and
$2,200,829, respectively.


Item 3.  Quantitative and Qualitative Disclosures about Market Risk

We are subject to financial market risks, including changes in interest rates.
At September 30, 2006, 88% of our long-term investments bear interest based on
floating rates, such as LIBOR, EURIBOR, 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. In addition, at September 30,
2006, 7% of our net portfolio consists of high quality short-term investments
and cash equivalents.

To illustrate the potential impact of changes in interest rates, we have
performed the following analysis based on our September 30, 2006 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 $2,300,000 in the value of our net assets at
September 30, 2006.

While hedging activities may insulate us against adverse changes in interest
rates, they may also limit our ability to participate in the benefits of lower
interest rates with respect to our portfolio of investments. During the three
and nine months ended September 30, 2006, we did not engage in any interest rate
hedging activities.

Item 4.  Controls and Procedures

As of the end of the period covered by this report, the Company 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 the
Company 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.
