NGP CAPITAL RESOURCES
COMPANY

NOTES TO CONSOLIDATED
FINANCIAL STATEMENTS

September 30, 2013

(Unaudited)



Note 1: Organization and Recent Developments



These consolidated financial statements
present the financial position, results of operations and cash flows of NGP Capital Resources Company and its consolidated subsidiaries.
The terms “we,” “us,” “our” and “NGPC” refer to NGP Capital Resources Company
and its consolidated subsidiaries. We are a financial services company organized in July 2004 as a Maryland corporation to invest
primarily in small and mid-size private energy companies. In early 2012, we expanded our investment strategy to also include middle
market companies not engaged in the energy industry. Our investment objective is to generate both current income and capital appreciation
primarily through debt investments with certain equity components. We are a closed-end, non-diversified management investment
company that has elected to be regulated as a business development company, or BDC, under the Investment Company Act of 1940,
or the 1940 Act. In addition, for federal income tax purposes we operate so as to be treated as a regulated investment company,
or RIC, under the Internal Revenue Code of 1986, as amended, or the Code. We have several direct and indirect subsidiaries that
are single member limited liability companies and wholly-owned limited partnerships established to hold certain portfolio investments
or provide services to us in accordance with specific rules prescribed for a company operating as a RIC. We consolidate the financial
results of our wholly-owned subsidiaries for financial reporting purposes, and we do not consolidate the financial results of
our portfolio companies. Our external manager, NGP Investment Advisor, LP, or our Manager, conducts our operations pursuant to
an Investment Advisory Agreement (see Note 4). NGP Energy Capital Management, L.L.C., or NGP, and NGP Administration, LLC, or
our Administrator, together own 100% of our Manager.



In September 2013, our Board of Directors
engaged financial advisor Keefe, Bruyette & Woods, a Stifel company, or KBW, to evaluate strategic alternatives to enhance
stockholder value. The Board of Directors, with the assistance of KBW, will consider a range of options, which may include a sale
or merger of our company, the acquisition of existing investment portfolios, or a combination, joint venture or other strategic
alliance with another company. No decision has been made to enter into a transaction at this time, and there can be no assurance
that we will enter into a transaction in the future.



Note 2: Basis of Presentation



These interim unaudited consolidated financial
statements include the accounts of NGPC and its subsidiaries. We eliminate all significant intercompany accounts and transactions.



We prepare the interim consolidated financial
statements, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC. We omit
certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting
principles generally accepted in the United States of America, or GAAP, pursuant to such rules and regulations. We believe
we include all adjustments, which are of a normal recurring nature, so that these financial statements fairly present our financial
position, results of operations and cash flows. Interim results are not necessarily indicative of results for a full year. You
should read these unaudited consolidated financial statements in conjunction with the consolidated financial statements and related
notes included in our Annual Report on Form 10-K for the year ended December 31, 2012.



Preparing interim consolidated financial
statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the consolidated
financial statements and the accompanying notes to the consolidated financial statements, including the estimated fair values
of our investment portfolio discussed in Note 7. Although we believe our estimates and assumptions are reasonable, actual
results could differ from these estimates.

Dividends



We record dividends to stockholders on
the ex-dividend date. We currently intend that our distributions each year will be sufficient to maintain our status as a RIC
for federal income tax purposes and to eliminate federal excise tax liability. We currently intend to make distributions to stockholders
on a quarterly basis that total substantially all net taxable income for the year. We also intend to make distributions of
net realized capital gains, if any, at least annually. However, we may in the future decide to retain such capital gains for investment
and designate such retained amounts as deemed distributions. Each quarter, our Manager estimates our annual taxable earnings.
The Board of Directors considers this estimate and determines the distribution amount, if any. We generally declare our dividends
each quarter and pay them shortly thereafter. The following table summarizes our recent distribution history:



|                   |  | Per Share |      |  |             |                    |

Note 3: Credit Facilities and Borrowings



On May 23, 2013, we entered into a $72.0
million Third Amended and Restated Revolving Credit Agreement, or the Investment Facility, which replaced our previous credit
facility. The total amount outstanding under the Investment Facility and our previous facility was $66.0 million and $59.5 million,
as of September 30, 2013 and December 31, 2012, respectively. Substantially all of our assets except our investments in U.S. Treasury
Bills are collateral for the obligations under the Investment Facility. The Investment Facility matures on May 23, 2016, and bears
interest, at our option, at either (i) LIBOR plus 325 to 475 basis points, or (ii) the base rate plus 225 to 375 basis points,
both based on our amounts outstanding. As of September 30, 2013, the average interest rate on our outstanding balance of $66.0
million was 4.4%. As of September 30, 2013, there was an additional $6.0 million available for borrowing under the Investment
Facility. We repaid $23.0 million of the outstanding balance in October 2013.



On March 31, 2011, we entered into a $30.0
million Treasury Secured Revolving Credit Agreement, or the Treasury Facility, which was later increased to $45.0 million, that
can only be used to purchase U.S. Treasury Bills. Proceeds from the Treasury Facility facilitate the growth of our investment
portfolio and provide flexibility in the sizing of our portfolio investments. On September 24, 2013, we entered into a fourth
amendment to the Treasury Facility which extended the expiration date to September 24, 2014 and increased the applicable margins
to either (i) LIBOR plus 150 basis points or (ii) the base rate plus 50 basis points. We have the right at any time to prepay
the loans, in whole or in part, without premium or penalty. As of September 30, 2013, we had $45.0 million outstanding and no
additional amount available for borrowing under the Treasury Facility, and the interest rate on our outstanding balance was 1.7%
(LIBOR plus 150 basis points). We repaid the entire balance outstanding under the Treasury Facility in October 2013 with proceeds
from the sale of U.S. Treasury Bills.



The Investment Facility and Treasury Facility
contain affirmative and reporting covenants and certain financial ratio and restrictive covenants that apply to our subsidiaries
and us. We complied with these covenants as of September 30, 2013 and had no existing defaults or events of default under either
facility. The most restrictive covenants are:

Note 4: Investment Management



Investment Advisory Agreement



We have an Investment Advisory Agreement
with our Manager under which our Manager administers our day-to-day operations and provides investment advisory services to us.
Our Manager is subject to the overall supervision of our Board of Directors. For providing these services, we pay our Manager
a fee, consisting of two components — a base management fee and an incentive fee.



Base Management Fee: According to
the Investment Advisory Agreement, we calculate the base management fee as 0.45% of the average of our total assets as of the
end of the two previous quarters. We record and pay this base management fee quarterly in arrears.



Incentive Fee: The incentive fee
under the Investment Advisory Agreement consists of two parts. We calculate the first part of the incentive fee, the Investment
Income Incentive Fee, as 20% of the excess, if any, of our net investment income for the quarter that exceeds a quarterly hurdle
rate equal to 2% (8% annualized) of our net assets. We calculate and pay this Investment Income Incentive Fee quarterly in arrears.
For the purpose of this fee calculation, net investment income means interest income, dividend income, royalty income and any
other income (including any other fees, such as commitment, origination, syndication, structuring, diligence, managerial assistance,
monitoring, and consulting fees or other fees that we receive from portfolio companies) accrued during the fiscal quarter, minus
our operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement,
and interest expense, but excluding the incentive fee). Accordingly, we may pay an incentive fee based partly on accrued interest,
the collection of which is uncertain or deferred. Net investment income includes, in the case of investments with a deferred interest
feature (such as original issue discount, or OID, debt instruments with payment-in-kind interest and zero coupon securities),
accrued income that we have not yet received in cash. Net investment income does not include any realized capital gains, realized
capital losses, or unrealized capital appreciation or depreciation. For the three and nine months ended September 30, 2013, we
incurred Investment Income Incentive Fees totaling $0 and $0.4 million, respectively. For the three and nine months ended September
30, 2012, we did not incur any Investment Income Incentive Fees.



We calculate the second part of the incentive
fee, the Capital Gains Fee, as (1) 20% of (a) our net realized capital gains (realized capital gains less realized capital losses)
on a cumulative basis from the closing date of our initial public offering to the end of such fiscal year, less (b) any unrealized
capital depreciation at the end of such fiscal year, less (2) the aggregate amount of all Capital Gains Fees paid to our Manager
in prior fiscal years. We determine and pay the Capital Gains Fee in arrears as of the end of each fiscal year (or upon termination
of the Investment Advisory Agreement, as of the termination date). For accounting purposes only, in order to reflect the theoretical
Capital Gains Fee that would be payable for a given period as if all unrealized capital gains were realized, we accrue a Capital
Gains Fee as described above (in accordance with the terms of the Investment Advisory Agreement), plus 20% of unrealized capital
gains on investments held at the end of such period. It should be noted that the portion of the accruals for the Capital Gains
Fees attributable to unrealized capital gains will not necessarily be payable under the Investment Advisory Agreement, and may
never be paid based on the computation of Capital Gains Fees in subsequent periods. As of September 30, 2013, we had cumulative
net capital losses of $72.9 million and cumulative net unrealized capital depreciation of $11.3 million. We did not incur or pay
any Capital Gains Fees for the three and nine month periods ended September 30, 2013 and 2012.



Our Board of Directors originally approved
the Investment Advisory Agreement on November 9, 2004. Our Board of Directors or the holders of a majority of our outstanding
voting securities must approve the continuation of the Investment Advisory Agreement at least annually. Additionally, in either
case, the approval must be by a majority of our independent directors. On October 30, 2013, our Board of Directors, including
all of the independent directors, approved an extension of the Investment Advisory Agreement through November 9, 2014.



14







The Investment Advisory Agreement may be
terminated at any time, without the payment of any penalty, by a vote of our Board of Directors or the holders of a majority of
our shares on 60 days’ written notice to our Manager, and would automatically terminate in the event of its “assignment”
(as defined in the 1940 Act). Either party may terminate the Investment Advisory Agreement without penalty upon not more than
60 days’ written notice to the other.



Pursuant to the Investment Advisory Agreement,
our Manager pays the compensation and routine overhead expenses of the investment professionals of our management team and their
respective staffs, when and to the extent engaged in providing management and investment advisory services to us. We bear all
other costs and expenses of our operations and transactions. Our Manager is a registered investment adviser under the Investment
Advisers Act of 1940.



Administration Agreement



We have an Administration Agreement with
our Administrator, under which our Administrator furnishes us with office facilities, equipment and clerical, bookkeeping and
recordkeeping services at such facilities. Under the Administration Agreement, our Administrator also performs, or oversees the
performance by third parties of, our required administrative services which include responsibility for the financial records that
we are required to maintain and preparation of reports to our stockholders and reports filed with the SEC. In addition, our Administrator
assists in determining and publishing our net asset value, oversees the preparation and filing of our tax returns, the printing
and dissemination of reports to our stockholders, and generally oversees the payment of our expenses and the performance of administrative
and professional services rendered to us by others. To the extent permitted under the 1940 Act, our Administrator may also provide,
on our behalf, significant managerial assistance to our portfolio companies. We base payments under the Administration Agreement
upon the allocable portion of our Administrator’s costs and expenses incurred in connection with administering our business.
The Administration Agreement may be terminated at any time, without penalty, by a vote of our Board of Directors or by our Administrator
upon 60 days’ written notice to the other party, and will automatically terminate in the event of its “assignment”
(as defined in the 1940 Act).



We owed $304,000 and $299,000 to our Administrator
as of September 30, 2013 and December 31, 2012, respectively, for expenses incurred on our behalf for the final month of the respective
quarterly period. We include these amounts in accounts payable and accrued expenses. Our Board of Directors originally approved
the Administration Agreement on November 9, 2004. Our Board of Directors and a majority of our independent directors must approve
the continuation of the Administration Agreement at least annually. On October 30, 2013, our Board of Directors, including all
of the independent directors, approved an extension of the Administration Agreement through November 9, 2014.



Note 5: Federal Income Taxes



We currently qualify for tax purposes as
a RIC under Subchapter M of Chapter 1 of the Code, as amended. As a RIC, the IRS generally will not tax the portion of our investment
company taxable income and net capital gain (i.e., realized net long term capital gains in excess of realized net short term capital
losses) distributed to stockholders. To qualify as a RIC, we are required, among other things, to distribute to our stockholders
at least 90% of investment company taxable income, as defined by the Code, and to meet certain asset diversification requirements.



Certain of our wholly-owned subsidiaries,
or Taxable Subsidiaries, have elected to be taxed as corporations for federal income tax purposes. The Taxable Subsidiaries
hold certain of our portfolio investments and are consolidated for financial reporting purposes, but not for income tax reporting
purposes. These Taxable Subsidiaries permit us to hold equity investments in portfolio companies that are “pass through”
entities for tax purposes, in order to comply with the “source income” requirements contained in the RIC tax regulations.
The Taxable Subsidiaries may generate net income tax expense or benefit, which is reflected on our consolidated statements of
operations.

Note 6: Commitments and Contingencies



As of September 30, 2013, we had investments
in or commitments to fund investments in 16 portfolio companies totaling $236.9 million. Of this total, $233.3 million was outstanding
and $3.6 million remained committed and available to fund. Generally, these commitments have fixed expiration dates, and we may
not fund the entire $3.6 million of commitments before they expire. We do not report the unfunded portions of these commitments
on our consolidated balance sheets.



We have continuing obligations under the
Investment Advisory Agreement with our Manager and under the Administration Agreement with our Administrator. The agreements provide
that, absent willful misfeasance, bad faith or gross negligence in the performance of its duties or the reckless disregard of
its duties and obligations, our Manager, our Administrator and their officers, managers, agents, employees, controlling persons,
members and any other person or entity affiliated with them will be entitled to indemnification from us for any damages, liabilities,
costs and expenses (including reasonable attorneys’ fees and amounts reasonably paid in settlement) arising from the rendering
of our Manager’s or Administrator’s services under the agreements or otherwise as our investment adviser or administrator.
The agreements also provide that our Manager, our Administrator and their affiliates will not be liable to us or any stockholder
for any error of judgment, mistake of law, any loss or damage with respect to any of our investments or any action taken or omitted
to be taken by our Manager or our Administrator in connection with the performance of any of their duties or obligations under
the agreements or otherwise as investment adviser or administrator to us, except to the extent specified in Section 36(b) of the
1940 Act concerning loss resulting from a breach of fiduciary duty with respect to the receipt of compensation for services. In
the normal course of business, we enter into a variety of undertakings containing a variety of representations that may expose
us to some risk of loss. We do not expect significant losses, if any, from such undertakings.



Legal Proceedings



From time to time, we are involved in various
legal proceedings arising in the normal course of business. While we cannot predict the outcome of these proceedings with certainty,
we do not believe that an adverse result in any pending legal proceeding other than those described below, individually or in
the aggregate, would be material to our business, financial condition or cash flows.



ATP Litigation. On August 17, 2012,
ATP Oil & Gas Corporation, or ATP, filed a petition for relief under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy
Court for the Southern District of Texas. We own limited term overriding royalty interests, or ORRIs, in certain offshore oil
and gas producing properties operated by ATP (generally, the Gomez and Telemark properties). On August 23, 2012, on a motion filed
by ATP (Bankr. Dkt. No.15), the bankruptcy judge presiding over ATP’s case signed an order (Bankr. Dkt. No. 191) allowing
ATP to pay amounts received after August 17, 2012 to those parties it believes are entitled to receive them, including the ORRI
holders, provided that the owners of the ORRIs execute a disgorgement agreement providing for the repayment to ATP of any amounts
that the bankruptcy court later finds to have been inappropriately paid. We executed the disgorgement agreement and began receiving
monthly distributions in September 2012 from ATP of our share of production proceeds received by ATP after August 17, 2012. As
of September 30, 2013, our unrecovered investment was $30.5 million, and we had received aggregate production payments of $21.7
million subject to the disgorgement agreement. In addition, as of September 30, 2013, we had incurred legal and consulting fees
totaling $2.9 million in connection with the enforcement of our rights under the ORRIs, $2.7 million of which has been added to
the unrecovered investment balance under the terms of the ORRI transaction documents. Legal and consulting fees totaling $0.2
million and $0.6 million as of September 30, 2013 and December 31, 2012, respectively, are included in accounts receivable and
other current assets on our consolidated balance sheets.

On October 17, 2012, we filed a lawsuit
against ATPstyled: NGP Capital Resources Company v. ATP Oil & Gas Corporation,
Adv. Proc. No. 12-03443, in the U.S. Bankruptcy Court for the Southern District of Texas, seeking a declaration that the ORRIs
are our property and not property of ATP and that the conveyance and purchase and sale documents are not executory contracts that
may be rejected in order to remove or recharacterize our interests in the properties. ATP filed an answer and counterclaim in
which it (a) denies that the ORRIs are valid and enforceable, (b) seeks a declaration that (i) the ORRIs are a financing agreement
and not a true sale and (ii) the ORRIs are executory contracts that are subject to rejection under 11 U.S.C. Sec. 365, and (c)
seeks disgorgement from us of amounts paid to us since August 17, 2012, the date of filing of ATP’s Chapter 11 proceeding.
The United States, on behalf of the Department of the Interior, intervened in the lawsuit, arguing that the underlying leases
are unexpired leases of real property or executory contracts (and not real property conveyances) and are subject to rejection
by ATP. Certain service companies claiming statutory liens or privileges have intervened in the lawsuit for the purposes of establishing
that their liens and privileges are superior to our rights and asserting related claims for disgorgement of proceeds paid to us
by ATP. The Bank of New York Mellon Trust Company, N.A., the secondary lien holder, has also intervened in the lawsuit, arguing
(i) the ORRIs are a financing agreement and not a true sale, (ii) our claims are barred, waived, released and/or otherwise foreclosed
by the express terms of the conveyance of the ORRIs, and (iii) either we have not met a condition precedent or we failed to perform
or substantially perform our contractual obligations. The issues in the lawsuit have been bifurcated such that the issues of (i)
whether the conveyances and transactions between us and ATP constituted outright transfers of ownership and (ii) whether the conveyances
are executory contracts or leases that ATP may reject, will be tried first. This lawsuit is currently pending, and the initial
trial date has been abated along with certain other deadlines pending the determination of various motions, including our motion
for summary judgment. We intend to vigorously defend our position that the ORRIs constitute real property interests and are fully
valid and enforceable pursuant to their terms, and we intend to vigorously defend our position that the service companies’
statutory liens and privileges do not attach to our ORRIs and/or are not superior to our rights.



Separately, on October 31, 2012, the Official
Committee of Unsecured Creditors of ATP, or the Committee, filed a motion requesting authority from the U.S. Bankruptcy Court
to be allowed to bring a fraudulent transfer action against us, in which the Committee seeks to allege that (a) ATP was insolvent
at the time of the assignment of the ORRIs to us, (b) that ATP received less than fair value from us in exchange for the assignments
of the ORRIs and (c) as a result, the assignments should be set aside. The Company vigorously denies these allegations and opposes
the motion. The motion has been abated until further notice.



On April 23, 2013, the Department of the
Interior, on behalf of the Bureau of Safety and Environmental Enforcement, issued an order directing that the wells on the Gomez
properties be shut in and that operations cease. Operations and production ceased on the Gomez properties on April 30, 2013.



On May 7, 2013, ATP conducted
an auction of its assets. At the conclusion of the auction, ATP selected a credit bid from Credit Suisse AG, as
administrative and collateral agent to those lenders who are parties to that certain Senior Secured Super Priority Priming
Debtor in Possession Credit Agreement dated August 29, 2012, or the DIP Lenders, based on a reduction in the amount of
ATP’s outstanding indebtedness to Credit Suisse AG, or the Credit Bid, as the highest and best bid. The Credit Bid did
not include an offer to purchase the Gomez properties but it included an offer to purchase the Telemark properties. On June
13, 2013, the Court entered an order (Bankr. Dkt. No. 1999) approving ATP’s request (set forth in Bankr. Dkt. No. 1902)
to reject and/or abandon and relinquish its interests in the Gomez properties and related agreements, or the Abandonment
Order. As a result of the shut-in of the Gomez wells and the Abandonment Order, our cash flows attributable to the ORRIs have
been negatively affected. On July 9, 2013, the Court entered its Interim Order (Bankr. Dkt. No. 2224) approving the sale
of ATP’s assets on an interim basis, subject to final approval upon consideration of evidence relating to the
proposed purchaser. On October 3, 2013, the purchaser Bennu Oil & Gas, LLC, or Bennu, a newly-formed company owned by the
DIP Lenders, filed its Statement In Support of the Sale (Bankr. Dkt. No. 2635). The final sale hearing was conducted October
17, 2013, after which the Court entered its Final Order approving the sale (Bankr. Dkt. No. 2706). Under the Final Order,
Bennu was authorized to purchase certain ATP assets, including the Telemark properties, as well as the claims asserted by ATP
in our pending lawsuit. Our ORRI continues to burden the Telemark properties subject to a resolution of the issues in our
pending lawsuit against ATP. The sale to Bennu closed on November 1, 2013.



GMX Resources, Inc. On April 1,
2013, GMX Resources, or GMX, and certain of its affiliates filed petitions for relief under Chapter 11 of the U.S. Bankruptcy
Code. In connection with its bankruptcy filing, GMX received a credit bid from certain senior first-lien creditors to acquire
substantially all of GMX’s operating assets and undeveloped acreage. On August 28, 2013, GMX completed a public auction
of its assets, with the credit bid prevailing. In October 2013, settlement motions were filed with the bankruptcy court that included
the establishment of a $1.5 million Litigation Trust, of which we would ultimately receive a pro rata share after deducting certain
trustee costs. The settlement motions are subject to the approval of the unsecured creditors and the bankruptcy court. We hold
$12.7 million face amount of GMX’s Senior Secured Second-Priority Notes due 2018, or the GMX 2018 Notes, which are subordinate
to the debt held by the senior creditors mentioned above. As a result of these proceedings, we reduced the estimated fair value
of our investment in the GMX 2018 Notes from $7.4 million as of December 31, 2012 to zero as of March 31, 2013.

We account for all of the assets in our
portfolio at fair value, following the provisions of the Financial Accounting Standards Board Accounting Standards Codification
Fair Value Measurements and Disclosures, or ASC 820. ASC 820 defines fair value, establishes a framework for measuring
fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value and enhances disclosure
requirements for fair value measurements.



On a quarterly basis, the investment team
of our Manager prepares fair value estimates for all of the assets in our portfolio utilizing the income approach and market approach
in accordance with ASC 820 and presents them to our Valuation Committee. The Valuation Committee recommends its fair value estimates
to our Board of Directors, which in good faith determines the final estimates of fair value for each investment. We record investments
in securities for which market quotations are readily available at such market quotations in our financial statements as of the
valuation date. For investments in securities for which market quotations are unavailable, or which have various degrees of trading
restrictions, the investment team of our Manager prepares valuation analyses as generally described below.

ASC 820 defines fair value as the price
that a seller would receive for an asset or pay to transfer a liability in an orderly transaction between independent, knowledgeable
and willing market participants at the measurement date. The fair value definition focuses on exit price in the principal, or
most advantageous, market and prioritizes the use of observable market inputs over unobservable entity-specific inputs. In
accordance with ASC 820, we categorize our investments based on the inputs to our valuation methodologies as follows:

Fair value accounting classifies financial
assets and liabilities in their entirety based on the lowest level of input that is significant to the estimated fair value measurement.
Our assessment of the significance of a particular input to the estimated fair value measurement requires judgment, and may affect
the valuation of assets and liabilities and their placement within the fair value hierarchy levels.



Debt Securities and Limited-Term Royalties:  In estimating the fair value of our debt investments, we first assess the overall financial health of the portfolio
company through an evaluation of a number of factors, including, as relevant, historical and projected financial results, the
portfolio company's enterprise value, and the nature and realizable value of any collateral. In estimating the portfolio
company’s enterprise value, we analyze the discounted value of estimated future net cash flows of the portfolio company,
derived, when appropriate, from third party valuations of a portfolio company’s assets, such as engineering reserve reports
of oil and natural gas properties. We also use a market approach in estimating the portfolio company’s estimated enterprise
value, considering recent comparable transactions involving similar businesses or assets. We also may consider the markets in
which the portfolio company operates; comparison to a peer group of publicly traded securities; the size and scope of the portfolio
company and its specific strengths and weaknesses; recent purchases or sales of securities by the portfolio company; recent offers
to purchase the portfolio company; the estimated value of comparable securities; and other relevant factors. Based upon these
analyses, we assess the sources of cash flow available to the portfolio company to service its debt and the underlying credit
risk, and determine an appropriate yield, or discount rate, to apply to our anticipated cash flows to be collected from each debt
investment, recognizing that the collection of contractual cash flows may come from one or a combination of cash flows generated
from continuing operations of the portfolio company, liquidation of collateral or sale of the portfolio company.  The
appropriateness of the yield on our investments is directly relative to our judgment of the associated risks, using observable
yield or price data for similar or comparable debt investments when available. Fair value measurements using the discounted
cash flow method can be sensitive to significant changes in the inputs. A significant increase (decrease) in the discount rate
for a particular security may result in a lower (higher) value for that security.

We invest primarily in illiquid debt investments
in small private companies, many of which are in the early stages of development, or are start-up companies in need of growth
development capital. There is limited activity, transparency and variable data in the markets in which we invest. We
have observed that there is limited correlation in yield and price data in our principle market when compared to overall market
trends based upon debt investments we have made throughout our history. In circumstances where there is limited observable  price
or yield data of similar or comparable securities, we base our considerations on our assessments of the credit trends and underlying
performance of our portfolio companies and of the markets in which we invest, relying on the collective judgment of the investment
team of our Manager, our Valuation Committee members and our Board of Directors, which is based on their extensive experience
and expertise investing in public and non-public securities markets.



Equity Securities: We
record our investments in preferred and common equity securities (including warrants or options to acquire equity securities)
at fair value based on our pro rata share of the residual equity value available after deducting all outstanding debt and other
obligations, as applicable, from the estimated enterprise value of the portfolio company. To estimate the enterprise value of
the portfolio company, we analyze the discounted cash flows of the portfolio company and indicative pricing (on a proved reserve
and/or units-of-production basis, as appropriate) in recent comparable market transactions as mentioned above, adjusted for lack
of marketability due to the illiquid nature or other restrictions on the sale of the security. In most cases, we may compute an
average of the calculated values of our share of the residual equity value (using multiple approaches or various assumptions)
in determining the fair value of the equity security to be reported in our financial statements. Estimating a company’s
enterprise value involves judgment, and residual equity values can be relatively volatile based on changes in market conditions,
the company’s financial performance and outlook, and other factors. Fair value measurements using market comparables can
be sensitive to significant changes in the inputs. A significant increase (decrease) in the reserve multiple, or a significant
decrease (increase) in the discount for lack of marketability, for a particular equity security may result in a higher (lower)
fair value for that security.



In some
cases, where we deem recent or pending financing or recapitalization transactions involving the portfolio company to be more indicative
of enterprise value, we use such recent transactions to value the enterprise, in lieu of the discounted cash flow or market comparables.
In addition, in cases where we deem appropriate, we utilize an option pricing method, or OPM, to value the various preferred stock,
common stock and warrants we have in companies with complex capital structures. The OPM treats preferred stock, common stock and
warrants as call options on the enterprise value, with exercise prices based on liquidation preference of the security. The OPM
commonly uses the Black-Scholes model to price the call option and considers the various terms of the stockholder agreements upon
liquidation of the enterprise. In addition, the OPM implicitly considers the effect of the liquidation preference as of a future
liquidation date, not as of the valuation date.



Royalty Interests: We record our
investments in overriding royalty interests at fair value based on a multiple of cash flows generated by such investments, multiples
from transactions involving the sale of comparable assets and/or the discounted value of expected future net cash flows from such
investments, adjusted for lack of marketability due to the illiquid nature or other restrictions on the sale of our investment.
We derive appropriate cash flow multiples from the review of comparable transactions involving similar assets. We derive the discounted
value of future net cash flows, when appropriate, from third party valuations of a portfolio company’s assets, such as engineering
reserve reports of oil and natural gas properties. A significant increase (decrease) in the cash flow multiple, or a significant
decrease (increase) in the discount for lack of marketability, for a particular investment may result in a higher (lower) fair
value for that investment.



Contingent Earn-Out: Our contingent
earn-out investment resulted from the sale of our investment in Alden Resources, LLC to Globe BG, LLC, or Globe, in July 2011.
The amount of the payment, up to $6.8 million, is based on a formula involving the number of clean tons of coal produced multiplied
by the difference between the company’s cost of production in 2010 and the cost of production during the optimal consecutive
twelve-month period during the three-year period ending July 2014. We based our valuation of the earn-out on a weighted average
of the discounted value of the earn-out payment computed under twenty scenarios with various production and production cost assumptions.
A significant increase (decrease) in production, a significant decrease (increase) in cost of production, or a significant decrease
(increase) in the discount rate may result in a higher (lower) value of the earn-out.

Commodity Derivative Instruments:
We record all derivative instruments at fair value. Quoted market prices are the best evidence of estimated fair value. We estimate
the fair value of the crude oil and natural gas options using a market-based valuation methodology based upon forward commodity
price and volatility curves. Independent pricing services provide the curves, which reflect broker market quotes. We consider
these investments as Level 2 on the valuation hierarchy, as the values represent quoted prices for similar instruments in active
markets.



We hold
certain investments in debt or equity securities that are publicly traded, but for which there are relatively few transactions
or for which trading activity is relatively infrequent. We value these investments at broker quotes as of the balance sheet date
or at prices for which such securities were most recently traded. We consider these investments as Level 2 on the valuation hierarchy,
as the values represent quoted prices for identical instruments in thinly-traded markets.



Due to
the inherent uncertainty in the valuation process, the fair value estimates for our investments may differ materially from the
values that would have been used had a ready market for the securities existed. Additionally, changes in the market environment,
portfolio company performance and other events that may occur over the lives of the investments may cause the gains or losses
ultimately realized on our investments to be materially different than the valuations currently assigned.



We have
investments in our portfolio that contain payment-in-kind, or PIK, provisions. We compute PIK interest income or PIK dividend
income at the contractual rate specified in each investment agreement and add that amount to the principal balance of the investment.
For those investments with PIK interest or PIK dividends, we calculate our income accruals on the principal balance plus any PIK
amounts. If the portfolio company’s projected cash flows, further supported by estimated total enterprise value, are not
sufficient to cover the contractual principal and interest or dividend amounts, as applicable, we do not accrue interest income
or dividend income on the investment. To maintain our RIC status, we must pay out this non-cash income to stockholders in the
form of dividends, even though we have not yet collected the cash.



Fair value
accounting classifies financial assets and liabilities in their entirety based on the lowest level of input that is significant
to the estimated fair value measurement. Our assessment of the significance of a particular input to the estimated fair value
measurement requires judgment, and may affect the valuation assets and liabilities and their placement within the fair value hierarchy
levels. We did not have any liabilities measured at fair value at September 30, 2013 or December 31, 2012. The following tables
set forth our financial assets by level within the fair value hierarchy that we accounted for at fair value as of September 30,
2013 and December 31, 2012.

The following
tables present roll-forwards, in thousands of dollars, of the changes in the estimated fair value during the three- and nine-month
periods ended September 30, 2013 and 2012 for all investments for which we determine estimated fair value using unobservable (Level
3) factors. During the three-month period ended March 31, 2013, our investment in Spirit Resources, LLC changed from a Non-Affiliate
investment to a Control Investment-Majority Owned. During the nine-month periods ended September 30, 2013 and 2012, no other investments
in portfolio companies changed between the categories of Control Investments – Majority Owned, Affiliate Investments and
Non-Affiliate Investments. During the three- and nine-month periods ended September 30, 2013, we transferred our investment in
Resaca common stock from Level 2 to Level 3 due to changes in the observability of significant inputs.

Note 8: Commodity Derivative Instruments



We use commodity derivative instruments
from time to time to manage our exposure to commodity price fluctuations. We use all of our derivatives for risk management purposes
and do not hold any amounts for speculative or trading purposes. These contracts generally consist of options contracts on underlying
commodities. We do not designate these instruments as hedging instruments for financial accounting purposes and, as a result,
we recognize the change in the instruments’ fair value currently on the consolidated statement of operations as net increase
(decrease) in unrealized appreciation (depreciation) on investments. All of our oil put options had expired as of September 30,
2013.

of 520,889 shares of our common stock in the open market at an average price of $6.49 per share, totaling $3.4 million, in accordance
with the stock repurchase plan approved by the Board of Directors in October 2011. These repurchases were made at an approximate

Overview



We are a financial services company created
to invest primarily in debt securities of small and mid-size private energy companies. In early 2012, we expanded our investment
strategy to also include middle market companies not engaged in the energy industry. We have elected to be regulated as a business
development company, or BDC, under the Investment Company Act of 1940, or the 1940 Act, and, as such, 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,” which include securities of private U.S. companies, U.S. companies whose securities are listed on a national securities
exchange but whose market capitalization is less than $250 million, cash, cash equivalents, U.S. government securities and high-quality
debt investments that mature in one year or less. In addition, for federal income tax purposes we operate so as to be treated
as a regulated investment company, or RIC, under the Internal Revenue Code of 1986, as amended. Pursuant to these elections, we
generally do not have to pay corporate-level taxes on any income and capital gains we distribute to our stockholders. We have
several direct and indirect subsidiaries that are single member limited liability companies and wholly-owned limited partnerships
established to hold certain portfolio investments or provide services to us in accordance with specific rules prescribed for a
company operating as a RIC. We consolidate the financial results of our subsidiaries for financial reporting purposes, and do
not consolidate the financial results of our portfolio companies.

Our investment objective is to generate
both current income and capital appreciation primarily through debt investments with certain equity components. A key focus area
for our investments in the energy industry is domestic upstream businesses that produce, develop, acquire and explore for oil
and natural gas. We also evaluate investment opportunities in such businesses as coal, power and energy services. We also target
middle market investments within diversified industry sectors, including manufacturing, value-added distribution, business services,
healthcare products and services, consumer services and select other sectors. Our investments generally range in size from $10
million to $50 million; however, we may invest more or less depending on market conditions and our Manager’s view of a particular
investment opportunity. Our portfolio investments primarily consist of debt instruments, including senior and subordinated loans
combined in one facility, sometimes with an equity component, and subordinated loans, sometimes with equity components. We may
also invest in preferred stock and other equity securities or royalty interests on a stand-alone basis.



We generate revenue in the form of interest
income on the debt securities and limited-term royalty interests that we own, dividend income on common or preferred stock that
we own, royalty income on royalty interests that we own and capital gains or losses on debt or equity securities that we acquire
in portfolio companies and subsequently sell. Our investments, if in the form of debt securities, typically have a term of three
to seven years and bear interest at a fixed or floating rate. To the extent achievable, we seek to collateralize our investments
by obtaining security interests in our portfolio companies' assets. We also may acquire minority or majority equity interests
in our portfolio companies, which may pay cash or paid-in-kind, or PIK, dividends on a recurring or otherwise negotiated basis.
In addition, we may generate revenue in other forms including commitment, origination, structuring, administration or due diligence
fees; fees for providing managerial assistance; and possibly consultation fees. We recognize any such fees generated in connection
with our investments as earned.



Our level of investment activity can and
does vary substantially from period to period depending on many factors. Some of these factors are the amount of debt and equity
capital available to energy companies, the level of acquisition and divestiture activity for such companies, the level and volatility
of energy commodity prices, the general economic environment and the competitive environment for the types of investments we make,
and our own ability to raise capital to fund our investments, both through issuance of debt and equity securities. While we currently
have capital available to invest, we do not have unlimited capital. We remain committed to our underwriting and investment disciplines
in selectively investing in appropriate risk-reward opportunities within the energy and middle market sectors.



In September 2013, our Board of Directors
engaged financial advisor Keefe, Bruyette & Woods, a Stifel company, or KBW, to evaluate strategic alternatives to enhance
stockholder value. The Board of Directors, with the assistance of KBW, will consider a range of options, which may include a sale
or merger of our company, the acquisition of existing investment portfolios, or a combination, joint venture or other strategic
alliance with another company. No decision has been made to enter into a transaction at this time, and there can be no assurance
that we will enter into a transaction in the future.



Portfolio and Investment Activity



On October 2, 2013, we funded a $14.0 million
participation in a $180.0 million Second Lien Term Loan, or the Term Loan, to a Houston-based, privately owned, independent oil
and gas exploration and production company, focused in the Gulf Coast region. Proceeds from the Term Loan were used to acquire
producing oil and gas properties in South Louisiana. The Term Loan was issued at a 3% discount, earns interest at the greater
of 10.25% or LIBOR + 9.0% per annum and matures on March 27, 2019.



On June 28, 2013, Resaca Exploitation,
Inc., or Resaca, completed the sale of substantially all of its oil and gas properties to Legacy Reserves Operating LP, a Midland,
Texas-based oil and gas company, for $72 million, subject to customary adjustments. In connection with the sale, we received a
cash payment of $16.1 million, representing full principal payment of our Senior Unsecured Term Loan and an interest “make
whole” provision of $2.2 million, or $0.11 per share. Subsequently, Resaca’s common stock, of which we own 1.36 million
shares, or 6.6% of Resaca’s common stock outstanding, has been delisted from the Alternative Investment Market of the London
Stock Exchange, and will ultimately be liquidated to shareholders as Resaca winds up its operations. Our investment in the Resaca
Term Loan resulted in an internal rate of return of 21.2% and a return on investment of 1.61x.



29







On June 14, 2013, Castex Energy Development
Fund, LP, or CDF, repaid its $55.0 million debt obligation under its Senior Secured Term Loan, including the $27.5 million face
amount that we held and an interest “make whole” provision to us of $0.3 million, or $0.01 per share. CDF also repurchased
the Class B LP units, resulting in net proceeds to us of $1.8 million, and a realized capital gain of $1.8 million, or $0.08 per
share. This investment was outstanding for 22 months and generated an internal rate of return of 17.8% and a return on investment
of 1.3x.



On May 24, 2013, we closed a $15.0 million
Senior Secured Term Loan to Crossroads Energy Development, LLC, or Crossroads, a Houston-based oil and gas company, with initial
availability of $11.0 million and initial funding of $9.0 million. Proceeds from the Senior Secured Term Loan were used to acquire
a 100% working interest in certain producing oil properties located in Central Louisiana and for the development of such properties.
The Senior Secured Term Loan earns interest at an annual rate of 11.5% (LIBOR + 10.5%) and matures in May 2016. As consideration
for providing the Term Loan, we also received a 2% overriding royalty interest in the properties and penny warrants to purchase
up to 18% of the operating subsidiary.



On April 22, 2013, we provided $17.5 million
of financing to Nekoosa Coated Products, or Nekoosa, a private manufacturer of carbonless sheets and specialty products used in
the commercial printing industry, in the form of a Second Lien Term Loan, to facilitate the acquisition of IGI Corp., a leading
manufacturer of specialty pressure sensitive graphic arts materials used in the signage and visual communications industry. The
Second Lien Term Loan earns interest payable in cash at an annual rate of 13% plus paid-in-kind interest of 2% per annum and matures
on October 22, 2018.



In 2011 and 2012, we purchased from ATP
Oil & Gas Corporation, or ATP, limited-term ORRIs in certain offshore oil and gas producing properties operated by ATP in
the Gulf of Mexico, including $25.0 million advanced on July 3, 2012. Under this arrangement, we own the right to portions (ranging
from 5.0% to 10.8%) of the monthly production proceeds from the various oil and gas properties subject to the ORRIs in ATP’s
Gomez and Telemark properties. The terms of the ORRIs provide that they will terminate after we receive payments that equal our
investment in the ORRIs plus a time-value factor that is calculated at a rate of 13.2 % per annum. On August 17, 2012, ATP filed
for protection under Chapter 11 of the U.S. Bankruptcy Code. For more information, please refer to the discussion of the ATP Litigation
under the heading “Legal Proceedings” in Note 6, “Commitments and Contingencies,” to Notes to Consolidated
Financial Statements included elsewhere in this Quarterly Report on Form 10-Q. As of September 30, 2013, our unrecovered investment
was $30.5 million, and we had received aggregate production payments of $21.7 million subject to a disgorgement agreement, $1.7
million of which was received during the third quarter of 2013. Production payments in the third quarter were lower than in previous
quarters in part because production from ATP’s Gomez properties ceased on April 30, 2013, and also because production from
the Telemark properties was temporarily shut-in for scheduled downstream pipeline maintenance. In addition, as of September 30,
2013, we had incurred legal and consulting fees totaling $2.9 million in connection with the enforcement of our rights under the
ORRIs, $2.7 million of which has been added to the unrecovered investment balance under the terms of the ORRI agreements. Legal
and consulting fees totaling $0.2 million and $0.6 million as of September 30, 2013 and December 31, 2012, respectively, are included
in accounts receivable and other current assets on our consolidated balance sheets.



On April 1, 2013, GMX Resources, or GMX,
and certain of its affiliates filed petitions for relief under Chapter 11 of the U.S. Bankruptcy Code. In connection with its
bankruptcy filing, GMX received a credit bid from certain senior first-lien creditors to acquire substantially all of GMX’s
operating assets and undeveloped acreage. On August 28, 2013, GMX completed a public auction of its assets, with the credit bid
prevailing. In October 2013, settlement motions were filed with the bankruptcy court that included the establishment of a $1.5
million Litigation Trust, of which we would ultimately receive a pro rata share, after deducting certain trustee costs. The settlement
motions are subject to approval of the unsecured creditors and the bankruptcy court. We hold $12.7 million face amount of GMX’s
Senior Secured Second-Priority Notes due 2018, or the GMX 2018 Notes, which are subordinate to the debt held by the senior creditors
mentioned above. As a result of these proceedings, we reduced the estimated fair value of our investment in the GMX 2018 Notes
to zero as of March 31, 2013, resulting in an unrealized loss of $7.4 million, or $0.35 per share.



On February 15, 2013, we closed a $17.5
million investment in OCI Holdings, LLC, or OCI. Our investment in OCI includes a $15.0 million Subordinated Note and a $2.5 million
direct equity co-investment. OCI is a home health provider of physical, occupational and speech therapy services to pediatric
patients in the state of Texas. Proceeds from the investment were used to refinance OCI and to finance OCI’s strategic acquisition
of a provider of similar services. The OCI Subordinated Note matures August 15, 2018 and earns interest payable in cash at a rate
of 11% per annum (LIBOR + 10%) plus paid-in-kind interest of 2% per annum.



30







On February 15, 2013, we provided $9.0
million of financing to KOVA International, Inc., or KOVA, in the form of Senior Subordinated Notes, to facilitate the acquisition
of the urinalysis division of Hycor Biomedical, Inc. by a group of private equity sponsors. Since 1974, the KOVA product lines
have been among the leading disposable plastics and liquid controls products used in the urinalysis testing market. The KOVA Senior
Subordinated Notes earn interest payable in cash at an annual rate of 12.75% and mature on August 15, 2018.



On February 6, 2013, we purchased $20.0
million of the $300 million 9.75% Senior Notes offering issued by Talos Production LLC and Talos Production Finance Inc., collectively,
Talos, to partially fund Talos’s acquisition of Energy Resource Technology GOM, Inc., the oil and gas subsidiary of Helix
Energy Solutions Group, Inc. On February 15, 2013, we purchased an additional $5.0 million face value of the Talos Senior Notes
in the secondary market. Talos is headquartered in Houston, Texas, and its parent company is a portfolio company of funds affiliated
with Apollo Global Management, LLC and Riverstone Holdings LLC, which committed up to $600 million in equity to Talos’s
parent company in February 2012. The Talos Senior Notes mature February 15, 2018, and were issued at 99.025 for an effective yield
of 10.0% per annum. During the second quarter of 2013, we sold $2.0 million face amount of Talos Senior Notes for $2.0 million.



On January 25, 2013, we restructured our
$13.5 million Senior Secured Term Loan, or the Original Term Loan, with Spirit Resources, LLC, or Spirit. Under the terms of the
restructuring, (i) $8.0 million of the Original Term Loan was converted into Preferred Units, with the remaining $5.5 million
structured as a Senior Secured Tranche A Term Loan; (ii) we provided $4.5 million of additional borrowing capacity in the form
of a Senior Secured Tranche B Term Loan; (iii) we received a 3% overriding royalty interest in Spirit’s oil and gas properties;
and (iv) we conveyed our 33% penny warrants back to Spirit. The Tranche A Term Loan matures April 28, 2015 and earns interest
payable monthly in cash at an annual rate of the greater of 8% or LIBOR + 4%. The Tranche B Term Loan matures October 28, 2015
and initially earns interest payable-in-kind at an annual rate of the greater of 15% or LIBOR + 11%. Beginning in January 2015,
interest on the Tranche B Term Loan is payable monthly in cash at an annual rate of the greater of 13% or LIBOR + 9%. Borrowings
under the Tranche B Term Loan are being used to execute relatively low-risk, high return development plans at Spirit’s oil
and gas properties and to provide additional working capital. The Preferred Units represent a preferred interest on 100% of any
equity distributions from Spirit until certain hurdles are met, after which Spirit management would participate in 25% of any
such distributions.



On January 25, 2013, Southern Pacific Resources
Corp., or STP, repaid its debt obligations under its $272.2 million Second Lien Term Loan, including the $9.8 million face amount
that we held, with a 1% call premium. Our investment in the STP Second Lien Term Loan, which was initially funded in the first
quarter of 2012, generated an internal rate of return of 10.7% with a return on investment of 1.09x.



Also in January 2013, we sold our remaining
$10.0 million face amount of EP Energy, LLC, or EP Energy, Senior Unsecured Notes at a price of 113.375 resulting in a realized
capital gain of $1.3 million, or $0.06 per common share. Our total investment in EP Energy Senior Unsecured Notes, which began
as a $25 million participation in their original issuance in April 2012, generated an internal rate of return of 36.5% with a
return on investment of 1.16x.



From commencement of investment operations
in November 2004 through September 30, 2013, we have invested $1.1 billion in 46 portfolio companies and received principal repayments,
realizations and settlements of $863.3 million. The following table summarizes our investment activity for the nine months ended
September 30, 2013 and 2012 (dollars in millions):

The table below shows our portfolio investments
by type as of September 30, 2013 and December 31, 2012. We compute yields on investments using interest rates as of the balance
sheet date and include amortization of original issue discount, or OID, and market premium or discount, royalty interest income,
net profits income and other similar investment income, weighted by their respective costs when averaged. We compute the yield
on income from derivatives using estimated derivative income, net of expired options costs. These yields do not include income
from any investments on non-accrual status but do include the cost basis of such investments in the denominator. Such weighted
average yields are not necessarily indicative of expected total returns on a portfolio.

Results of Operations



Investment Income



During the three months ended September
30, 2013, our total investment income was $6.0 million, decreasing $0.3 million, or 6%, compared to $6.3 million in the corresponding
period of 2012. The small decrease in 2013 was primarily attributable to slightly lower overall portfolio balances partially offset
by slightly higher weighted average yields. Our portfolio balance, on a cost basis, decreased from $233.7 million at September
30, 2012 to $227.8 million at September 30, 2013, primarily as a result of net redemptions and settlements in excess of new investments.
Our weighted average yields increased slightly from 10.1% at September 30, 2012 to 10.5% at September 30, 2013, primarily as a
result of the write off of our non-accruing and non-income producing investments in BioEnergy Holding, LLC and Bionol Clearfield,
LLC during December 2012, and the addition of new investments in the portfolio.



During the nine months ended September
30, 2013, investment income increased by $4.1 million, or 24%, to $21.4 million compared to $17.3 million during the same period
in 2012. The increase in 2013 is primarily attributable to $2.5 million of “make whole” interest from the early repayments
of loans from CDF and Resaca and higher average portfolio balances during 2013.

For the three months ended September 30,
2013, operating expenses were $3.3 million, increasing $0.4 million, or 15%, compared to $2.9 million for the quarter ended September
30, 2012. Interest expense and fees on our credit facilities were $0.7 million for the three months ended September 30, 2013,
compared to $0.6 million for the three months ended September 30, 2012, as a result of increased borrowing levels supporting our
larger investment portfolio. Management and incentive fees were higher in the quarter ended September 30, 2013 at $1.4 million
compared to $1.1 million for the quarter ended September 30, 2012, primarily as a result of higher average total asset balances,
which are the basis for the base management fee computation.



For the nine months ended September 30,
2013, operating expenses were $10.9 million, increasing $2.7 million, or 33%, compared to $8.2 million for the nine months ended
September 30, 2012. Interest expense and fees on our credit facilities increased to $2.5 million for the nine months ended September
30, 2013, compared to $1.3 million for the nine months ended September 30, 2012, as a result of increased borrowing levels supporting
our larger investment portfolio. Management and incentive fees were higher in the first nine months of 2013 at $4.6 million compared
to $3.3 million in the prior year period, primarily as a result of higher average total asset balances, which are the basis for
the base management fee computation. In addition, management and incentive fees include investment income incentive fees of $0.4
million in 2013, as a result of our net investment income exceeding the quarterly hurdle rate of 2% in the second quarter of 2013.



Operating expenses include our allocable
portion of the total organizational and operating expenses incurred by us, our Manager and our Administrator, as determined by
our Board of Directors and representatives of our Manager and our Administrator. According to the terms of the Investment Advisory
Agreement, we calculate the base management fee quarterly as 0.45% of the average of our total assets as of the end of the two
previous quarters. Other general and administrative expenses include our allocated share of employee, facilities, stockholder
services and marketing costs incurred by our Administrator.



Net Investment Income



For the three months ended September 30,
2013, net investment income was $2.6 million, or $0.13 per common share, compared to $3.4 million, or $0.16 per common share,
for the three months ended September 30, 2012. The $0.8 million, or 23%, decrease was attributable to the $0.4 million decrease
in investment income, and the $0.4 million increase in operating expenses, both of which are described above.



For the nine months ended September 30,
2013, net investment income was $10.4 million, or $0.50 per common share, compared to $9.0 million, or $0.42 per common share,
for the nine months ended September 30, 2012. The $1.4 million, or 16%, increase was attributable to the $4.1 million increase
in investment income, partially offset by the $2.7 million increase in operating expenses, both of which are described above.



Net Realized Gains (Losses)



We did not realize any gains or losses
on investments during the three months ended September 30, 2013. For the three months ended September 30, 2012, we recognized
net realized capital gains of $1.7 million resulting primarily from the sale of $15.0 million face amount of EP Energy Senior
Unsecured Notes at an average price of 108.5, for a gain of $1.3 million, and the sale of our Anadarko Petroleum Corporation 2007-III
Drilling Fund, or APC, Tail Net Profits Interest for $0.4 million.



For the nine months ended September 30,
2013, we recognized net realized capital gains of $0.8 million resulting from a $1.8 million gain from the sale of our Class B
LP units of CDF and a $1.3 million gain from the sale of $10.0 million face amount of EP Energy Senior Unsecured Notes at an average
price of 113.375, partially offset by a $1.6 million loss from the sale of our 228,853 shares of GMX common stock at an average
price of $3.28 per share, a $0.2 million loss on the disposition of our Resaca warrants and a $0.5 million loss resulting from
adjustments to the amounts recorded on our 2011 sales of our investments in Alden Resources, LLC and DeanLake Operator, LLC. For
the nine months ended September 30, 2012, we recognized net realized capital gains of $1.7 million as described above.

Unrealized Appreciation or Depreciation on Investments



For the three months ended September 30,
2013, net unrealized appreciation on portfolio investments was $2.5 million, or $0.12 per share, primarily due to increases in
the estimated fair value of our investments in Talos Senior Unsecured Notes of $1.3 million, Midstates Petroleum Company, or Midstates,
Senior Unsecured Notes of $0.6 million, Crossroads ORRI and warrants totaling $0.5 million and net increases in the value of remaining
investments of $0.1 million. By comparison, for the three months ended September 30, 2012, net unrealized appreciation was $7.1
million, largely due to increases in the estimated fair value of our investments in Huff Energy Holdings, Inc., or HEH, of $6.0
million, GMX of $2.2 million and Castex 2005 Preferred Units of $1.1 million, partially offset by decreases in the values of our
investments in Globe BG, LLC, or Globe, of $2.1 million and Resaca, of $0.6 million. Net increases in the estimated fair value
of remaining investments totaled $0.5 million.



For the nine months ended September 30,
2013, net unrealized depreciation on portfolio investments was $10.2 million, or $0.49 per share, primarily due to decreases in
the estimated fair value of our investments in GMX 2018 Notes of $7.4 million and Spirit preferred units and overriding royalty
interests of $4.3 million, partially offset by increases in the fair value of Castex 2005 Preferred Units of $1.1 million and
net increases in our remaining investments of $0.4 million. By comparison, for the nine months ended September 30, 2012, net unrealized
appreciation was $6.9 million, primarily due to increases in estimated fair value of our investments of $3.7 million for HEH,
$3.2 million for GMX, $1.1 million for Castex 2005 Preferred Units, and $1.9 million for CDF, Class B LP Units, offset by decreases
in the estimated fair value of $2.9 million for Globe and $1.2 million for Resaca. Net increases in the estimated fair value of
remaining investments totaled $1.1 million.



Net Increase (Decrease) in Net Assets Resulting
from Operations



For the three months ended September 30,
2013, we recorded a net increase in net assets resulting from operations of $5.1 million, or $0.25 per share, compared to $12.2
million, or $0.57 per share, for the three months ended September 30, 2012. The $7.1 million, or $0.32 per share, decrease between
the two periods was primarily attributable to the $0.7 million decrease in net investment income and the $6.4 million decrease
in net realized and unrealized gains on our investments, both of which are described above.



For the nine months ended September 30,
2013, we recorded a net increase in net assets resulting from operations of $1.0 million, or $0.05 per share, compared to a net
increase in net assets resulting from operations of $17.5 million, or $0.82 per share, for the nine months ended September 30,
2012. The $16.6 million, or $0.77 per share, net change between the two periods was primarily attributable to the $18.0 million
decrease in net realized and unrealized gains on our investments, partially offset by a $1.4 million increase in net investment
income, both of which are described above.



Financial Condition, Liquidity and Capital Resources



During the nine months ended September
30, 2013, we generated cash from operations of $8.8 million, excluding net purchases of investments, compared to $6.8 million
during the comparable period of 2012. The higher amount of cash generated from operations in 2013 was primarily attributable to
increased net investment income and a lower amount of non-cash investment income in 2013 compared to 2012.



Our net cash provided by operating activities
for the nine months ended September 30, 2013 was $1.5 million, compared to $96.3 million of net cash used in operating activities
for the same period of 2012. This increase in net cash provided in 2013 was primarily due to lower net purchases of investments
in portfolio securities and U.S. Treasury Bills in 2013. Purchases of portfolio securities during the first nine months of 2013
totaled $84.9 million, compared to $111.1 million during the first nine months of 2012. Purchases in 2013 primarily included the
Talos Senior Notes of $24.8 million, OCI Subordinated Notes and direct equity co-investment totaling $17.2 million, Nekoosa Second
Lien Term Loan of $17.2 million, KOVA Senior Subordinated Notes of $8.8 million, Crossroads Senior Secured Term Loan of $8.8 million
and additional investments in existing portfolio companies totaling $8.1 million. Purchases in 2012 primarily included the Castex
2005 Preferred Units of $50.0 million, EP Energy Senior Notes of $25.0 million, an additional investment in ATP of $25.0 million,
the STP Term Loan of $10.0 million and additional investments in existing portfolio companies totaling $1.1 million. Proceeds
from the redemption of investments totaled $77.6 million during the first nine months of 2013, compared to $54.0 million during
the first nine months of 2012. Redemptions in 2013 included CDF Senior Secured Term Loan and Class B LP units, $29.3 million;
Resaca Senior Unsecured Term Loan, $13.7 million; EP Energy Senior Unsecured Notes, $11.3 million; STP Term Loan, $9.7 million;
ATP, $9.3 million and other redemptions totaling $4.3 million. Redemptions in 2012 included EP Energy, $16.3 million; ATP, $10.8
million; Tammany Oil & Gas, LLC, $10.1 million; Crestwood Holdings, LLC, $8.3 million; Pallas Contour Mining, LLC, $4.1 million,
APC, $3.6 million; and other redemptions totaling $0.8 million. During the first nine months of 2013, we also purchased and redeemed
$138.0 million in U.S. Treasury Bills with borrowings under our Treasury Secured Revolving Credit Agreement, or the Treasury Facility,
compared to $56.2 million purchased and $10.2 million redeemed during the first nine months of 2012.



35







At September 30, 2013, we had cash and
cash equivalents totaling $42.3 million. At September 30, 2013, the amount outstanding under our $72.0 million Third Amended and
Restated Revolving Credit Agreement, or the Investment Facility, was $66.0 million and $6.0 million was available for borrowing.
We repaid $23.0 million of the $66.0 million balance outstanding under the Investment Facility in October 2013. As of September
30, 2013, the amount outstanding under our $45.0 million Treasury Facility was $45.0 million and there was no additional amount
available for borrowing. We repaid the entire balance outstanding under the Treasury Facility in October 2013.



During the nine months ended September
30, 2013, we paid cash dividends totaling $10.0 million, or $0.48 per share, to our common stockholders. In September 2013, we
declared a third quarter dividend totaling $3.3 million, or $0.16 per share, which was paid in October 2013. We currently intend
to continue to distribute, in the form of quarterly dividends, a minimum of 90% of our annual investment company taxable income
to our stockholders.



On October 31, 2011, our Board of Directors
approved a stock repurchase plan, pursuant to which we may, from time to time, repurchase up to $10.0 million of our common stock
in the open market at prices not to exceed net asset value during our open trading periods. Our Board of Directors authorized
this plan, because it believes that general market trading activity may cause our common stock to be undervalued from time to
time. The repurchase program does not obligate us to purchase any shares and may be discontinued at any time. Pursuant to this
plan, during the nine months ended September 30, 2013, we repurchased an aggregate of 520,889 shares of our common stock in the
open market at an average price of $6.49 per share, totaling $3.4 million. We did not make any repurchases pursuant to the stock
repurchase plan during the three months ended September 30, 2013. During the nine months ended September 30, 2012, we repurchased
an aggregate of 250,029 shares of our common stock at an average price of $6.51 per share, totaling $1.6 million. Under the terms
of the stock repurchase plan, we are authorized to repurchase up to an additional $2.4 million of our common stock. Any future
repurchases will be made in accordance with applicable securities laws and regulations that set certain restrictions on the method,
timing, price and volume of stock repurchases.



Commodity Derivative Instruments



We use commodity derivative instruments
from time to time to manage our exposure to commodity price fluctuations. We use all of our derivatives for risk management purposes
and do not hold any amounts for speculative or trading purposes. We do not designate these instruments as hedging instruments
for financial accounting purposes, and, as a result, we recognize the change in the instruments’ fair value currently on
the consolidated statements of operations as net increase (decrease) in unrealized appreciation (depreciation) on investments.
In December 2011, in connection with our purchase of a limited term royalty interest from ATP, we purchased a series of oil put
options to provide insurance against downside price movements. All of our put options had expired as of September 30, 2013. See
Note 8 of Notes to Consolidated Financial Statements included elsewhere herein for further description of our put options.



Credit Facilities and Borrowings



On May 23, 2013, we entered into a $72.0
million Investment Facility, which replaced our previous credit facility. The total amount outstanding under the Investment Facility
and our previous facility was $66.0 million and $59.5 million, as of September 30, 2013 and December 31, 2012, respectively. Substantially
all of our assets except our investments in U.S. Treasury Bills are collateral for the obligations under the Investment Facility.
The Investment Facility matures on May 23, 2016, and bears interest, at our option, at either (i) LIBOR plus 325 to 475 basis
points, or (ii) the base rate plus 225 to 375 basis points, both based on our amounts outstanding. As of September 30, 2013, the
average interest rate on our outstanding balance of $66.0 million was 4.4%. As of September 30, 2013, there was an additional
$6.0 million available for borrowing under the Investment Facility. We repaid $23.0 million of the outstanding balance in October
2013.





36









On March 31, 2011, we entered into a $30.0
million Treasury Facility, which was later increased to $45.0 million that can only be used to purchase U.S. Treasury Bills. Proceeds
from the Treasury Facility facilitate the growth of our investment portfolio and provide flexibility in the sizing of our portfolio
investments. On September 24, 2013, we entered into a fourth amendment to the Treasury Facility which extended the expiration
date to September 24, 2014 and increased the applicable margins to either (i) LIBOR plus 150 basis points or (ii) the base rate
plus 50 basis points. We have the right at any time to prepay the loans, in whole or in part, without premium or penalty. As of
September 30, 2013, we had $45.0 million outstanding and no additional amount available for borrowing under the Treasury Facility,
and the interest rate on our outstanding balance was 1.7% (LIBOR plus 150 basis points). We repaid the entire balance outstanding
under the Treasury Facility in October 2013 with proceeds from the sale of U.S. Treasury Bills.



The Investment Facility and Treasury Facility
contain affirmative and reporting covenants and certain financial ratio and restrictive covenants that apply to our subsidiaries
and us. We complied with these covenants as of September 30, 2013 and had no existing defaults or events of default under either
facility. The most restrictive covenants are:

In addition to proceeds from borrowings
under our Investment Facility, we may also fund a portion of our investments with issuances of equity or senior debt securities.
We expect our primary use of funds to be investments in portfolio companies, cash distributions to holders of our common stock
and payment of fees and other operating expenses.



Dividends



We have elected to operate our business
to be taxed as a RIC for federal income tax purposes. As a RIC, we generally may not pay corporate-level federal income taxes
on any ordinary income or capital gains that we distribute to our stockholders as dividends. To maintain our RIC status, we must
meet specific source-of-income and asset diversification requirements and distribute annually an amount equal to at least 90%
of our “investment company taxable income” (which generally consists of ordinary income and realized net short-term
capital gains in excess of realized net long-term capital losses, if any, reduced by deductible expenses) and net tax-exempt interest.
In order to avoid certain excise taxes imposed on RICs, we must 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) 98.2% of our capital gain net income (i.e., realized capital
gains in excess of realized capital losses) for the one-year period ended on October 31 of that calendar year, and (3) 100% of
any ordinary income or capital gain net income not distributed in prior years. We currently intend to make sufficient distributions
to satisfy the annual distribution requirement and to avoid the excise taxes.



We may not achieve operating results that
will allow us to make distributions at a specific level or to increase the amount of these distributions from time to time. In
addition, we may be limited in our ability to make distributions due to the asset coverage test for borrowings when applicable
to us as a BDC under the 1940 Act and due to provisions in our Investment Facility. If we do not distribute a certain percentage
of our income annually, we will suffer adverse tax consequences, including possible loss of our status as a RIC. We cannot assure
stockholders that they will receive any distributions or distributions at any specific level.

Portfolio Credit Quality



Most of our portfolio investments at September
30, 2013 are in negotiated, and often illiquid, securities of private businesses. We maintain a system to evaluate the credit
quality of these investments. While incorporating quantitative analysis, this system is a qualitative assessment. This system
is intended to reflect the overall, long-term performance of a portfolio company’s business, the collateral coverage of
an investment, and other relevant factors. Our rating scale ranges from 1 to 7, with 1 being the highest credit quality. As of
September 30, 2013, our average portfolio rating on a dollar-weighted fair market value basis was 3.9, compared to 4.1 as of December
31, 2012. Of the 26 rated investments in 16 portfolio companies as of September 30, 2013, 9 investments retained the same rating
as of December 31, 2012, 2 investments improved in rating, 3 investments declined and we added 10 new investments to our portfolio
during the first nine months of 2013. We also added 2 existing equity investments to the rating system that were not previously
rated. As of September 30, 2013, on a fair value basis, approximately 16% of our portfolio investments were in the form of senior
secured debt securities. As of September 30, 2013, we had 2 investments on non-accrual status with an aggregate cost and fair
value of $13.8 million and less than $0.1 million, respectively. Our portfolio investments at fair value were approximately 94%
and 98% of the related cost basis as of September 30, 2013 and December 31, 2012, respectively.

| | (1) | Excludes accrued interest amounts.
| | --- | ----------------------------------



We have certain unused commitments to extend
credit to our portfolio companies. Generally, these commitments have fixed expiration dates, and we do not expect to fund the
entire amounts before they expire. Therefore, these commitment amounts do not necessarily represent future cash requirements.
In February 2010, we arranged for a letter of credit issued under the Investment Facility with respect to our investment in one
of our portfolio companies. This letter of credit expired in February 2013. We do not report the unused portions of these commitments
on our consolidated balance sheets. The following table shows our unused credit commitments and letter of credit as of September
30, 2013 and December 31, 2012 (in thousands):

In connection with the preparation of this
