Item 1.    Business 

ORGANIZATION

PART I 

       Main Street Capital Corporation ("MSCC") is a principal investment firm primarily focused on providing customized debt and equity
financing to lower middle market ("LMM") companies and debt capital to middle market ("Middle Market") companies. The portfolio
investments of MSCC and its consolidated subsidiaries are typically made to support management buyouts, recapitalizations, growth
financings, refinancings and acquisitions of companies that operate in a variety of industry sectors. MSCC seeks to partner with
entrepreneurs, business owners and management teams and generally provides "one stop" financing alternatives within its LMM portfolio.
MSCC and its consolidated subsidiaries invest primarily in secured debt investments, equity investments, warrants and other securities of
LMM companies based in the United States and in secured debt investments of Middle Market companies generally headquartered in the
United States.

       MSCC was formed in March 2007 to operate as an internally managed business development company ("BDC") under the Investment
Company Act of 1940, as amended (the "1940 Act"). MSCC wholly owns several investment funds, including Main Street Mezzanine
Fund, LP ("MSMF"), Main Street Capital II, LP ("MSC II") and Main Street Capital III, LP ("MSC III" and, collectively with MSMF and
MSC II, the "Funds"), and each of their general partners. The Funds are each licensed as a Small Business Investment Company ("SBIC")
by the United States Small Business Administration ("SBA"). Because MSCC is internally managed, all of the executive officers and other
employees are employed by MSCC. Therefore, MSCC does not pay any external investment advisory fees, but instead directly incurs the
operating costs associated with employing investment and portfolio management professionals.

       MSC Adviser I, LLC (the "External Investment Manager") was formed in November 2013 as a wholly owned subsidiary of MSCC to
provide investment management and other services to parties other than MSCC and its subsidiaries or their portfolio companies ("External
Parties") and receives fee income for such services. MSCC has been granted no-action relief by the SEC to allow the External Investment
Manager to

1

Table of Contents

register as a registered investment adviser under the Investment Advisers Act of 1940, as amended (the "Advisers Act"). Since the External
Investment Manager conducts all of its investment management activities for External Parties, it is accounted for as a portfolio investment
of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated financial statements.

       MSCC has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M
of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSCC generally will not pay corporate-level U.S. federal
income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

       MSCC has certain direct and indirect wholly owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries").
The primary purpose of the Taxable Subsidiaries is to permit MSCC to hold equity investments in portfolio companies which are "pass-
through" entities for tax purposes.

       Unless otherwise noted or the context otherwise indicates, the terms "we," "us," "our," the "Company" and "Main Street" refer to
MSCC and its consolidated subsidiaries, which include the Funds and the Taxable Subsidiaries.

       The following diagram depicts our organizational structure:

*

**

Other Holding Companies includes the Taxable Subsidiaries and other entities formed for operational purposes. Each of these
companies is directly or indirectly wholly owned by MSCC. 

The External Investment Manager is accounted for as a portfolio investment at fair value, as opposed to a consolidated subsidiary,
and is indirectly wholly owned by MSCC.

CORPORATE INFORMATION

       Our principal executive offices are located at 1300 Post Oak Boulevard, 8 th Floor, Houston, Texas 77056. We maintain a Web site on
the Internet at www.mainstcapital.com. We make available free of charge on our Web site our annual reports on Form 10-K, quarterly
reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after such
material is electronically filed with or furnished to the SEC. Information contained on our Web site is not incorporated by reference into
this Annual Report on Form 10-K, and you should not consider that information to be part of this Annual Report on Form 10-K. Our annual
reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports and other public
filings are also available free of charge on the EDGAR Database on the SEC's Web site at www.sec.gov.

OVERVIEW OF OUR BUSINESS

       Our principal investment objective is to maximize our portfolio's total return by generating current income from our debt investments
and capital appreciation from our equity and equity-related investments,

2

Table of Contents

including warrants, convertible securities and other rights to acquire equity securities in a portfolio company. Our LMM companies
generally have annual revenues between $10 million and $150 million, and our LMM portfolio investments generally range in size from
$5 million to $50 million. Our Middle Market investments are made in businesses that are generally larger in size than our LMM portfolio
companies, with annual revenues typically between $150 million and $1.5 billion, and our Middle Market investments generally range in
size from $3 million to $20 million. Our private loan ("Private Loan") portfolio investments are primarily debt securities in privately held
companies which have been originated through strategic relationships with other investment funds on a collaborative basis. Private Loan
investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and Middle Market
portfolio.

       We seek to fill the financing gap for LMM businesses, which, historically, have had limited access to financing from commercial banks
and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM
companies while also negotiating favorable transaction terms and equity participations. Our ability to invest across a company's capital
structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options, or a
"one stop" financing solution. Providing customized, "one stop" financing solutions is important to LMM portfolio companies. We
generally seek to partner directly with entrepreneurs, management teams and business owners in making our investments. Our LMM
portfolio debt investments are generally secured by a first lien on the assets of the portfolio company and typically have a term of between
five and seven years from the original investment date.

       Our Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing debt
securities in privately held companies that are generally larger in size than the companies included in our LMM portfolio. Our Middle
Market portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and
typically have an expected duration of between three and seven years from the original investment date.

       Our Private Loan portfolio investments are primarily debt securities in privately held companies which have been originated through
strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt markets as "club deals."
Private Loan investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and
Middle Market portfolio. Our Private Loan portfolio debt investments are generally secured by either a first or second priority lien on the
assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

       Our other portfolio ("Other Portfolio") investments primarily consist of investments which are not consistent with the typical profiles
for our LMM, Middle Market or Private Loan portfolio investments, including investments which may be managed by third parties. In our
Other Portfolio, we may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in
other investment companies or private funds.

       Our external asset management business is conducted through the External Investment Manager. The External Investment Manager
earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the
performance of the funds managed. We have entered into an agreement with the External Investment Manager to share employees in
connection with its asset management business generally, and specifically for its relationship with HMS Income Fund, Inc. ("HMS
Income"). Through this agreement, we share employees with the External Investment Manager, including their related infrastructure,
business relationships, management expertise and capital raising capabilities.

       Our portfolio investments are generally made through MSCC and the Funds. MSCC and the Funds share the same investment
strategies and criteria, although they are subject to different regulatory regimes (see "Regulation"). An investor's return in MSCC will
depend, in part, on the Funds' investment returns as they are wholly owned subsidiaries of MSCC.

       The level of new portfolio investment activity will fluctuate from period to period based upon our view of the current economic
fundamentals, our ability to identify new investment opportunities that meet our investment criteria, and our ability to consummate the
identified opportunities. The level of new investment activity, and associated interest and fee income, will directly impact future investment
income. In addition, the level of dividends paid by portfolio companies and the portion of our portfolio debt investments on non-accrual
status will directly impact future investment income. While we intend to grow our portfolio and our investment income over the long term,
our growth and our operating results may be more limited during depressed economic periods. However, we intend to appropriately manage
our cost structure and liquidity position based on applicable economic conditions and our investment outlook. The level of realized gains or
losses and unrealized appreciation or depreciation on our investments will also fluctuate depending upon portfolio activity, economic
conditions and the performance of our individual portfolio companies. The changes in realized gains and losses and unrealized appreciation
or depreciation could have a material impact on our operating results.

       Because we are internally managed, we do not pay any external investment advisory fees, but instead directly incur the operating costs
associated with employing investment and portfolio management professionals. We believe that our internally managed structure provides
us with a beneficial operating expense structure when compared to other publicly traded and privately held investment firms which are
externally managed, and our internally managed structure allows us the opportunity to leverage our non-interest operating expenses as we
grow our Investment Portfolio.

       During May 2012, we entered into an investment sub-advisory agreement with HMS Adviser, LP ("HMS Adviser"), which is the
investment advisor to HMS Income, a non-listed BDC, to provide certain investment advisory services to HMS Adviser. In December
2013, after obtaining required no-action relief from the SEC to allow us to own a registered investment adviser, we assigned the sub-
advisory agreement to the External Investment Manager since the fees received from such arrangement could otherwise have negative
consequences on our ability to meet the source-of-income requirement necessary for us to maintain our RIC tax treatment. Under the
investment sub-advisory agreement, the External Investment Manager is entitled to 50% of the base management fee and the incentive fees
earned by HMS Adviser under its advisory agreement with HMS Income.

       During April 2014, we received an exemptive order from the SEC permitting co-investments by us and HMS Income in certain
negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. We have made, and in the future intend to
continue to make, such co-investments with HMS Income in accordance with the conditions of the order. The order requires, among other
things, that we and the External Investment Manager consider whether each such investment opportunity is appropriate for HMS Income
and, if it is appropriate, to propose an allocation of the investment opportunity between us and HMS Income. Because the External
Investment Manager may receive performance-based fee compensation from HMS Income, this may provide it an incentive to allocate
opportunities to HMS Income instead of us. However, both we and the External Investment Manager have policies and procedures in place
to manage this conflict.

RECENT DEVELOPMENTS

       In January 2019, we led a new portfolio investment to facilitate the minority recapitalization of Centre Technologies, Inc. ("Centre"), a
premier provider of IT hardware, software and service solutions. We, along with our co-investors, partnered with Centre's founder and
Chief Executive Officer and management team to facilitate the transaction, with us funding $18.1 million in a combination of first-lien,
senior secured term debt and a direct equity investment. Headquartered in Houston, Texas, and founded in 2006, Centre has established
itself as a mission critical IT solutions provider offering a full suite of solutions including managed and hosted services, value-added
sourcing and integration, and project services.

       In January 2019, we led a new portfolio investment to facilitate the management buyout of CompareNetworks Inc.
("CompareNetworks"), a leading provider of media, marketing and technology

Table of Contents

solutions that drive revenue for life science and healthcare product manufacturers. We, along with our co-investors, partnered with
CompareNetworks' founders and management team to facilitate the transaction, with us funding $10.7 million in a combination of first-lien,
senior secured term debt and a direct equity investment. Headquartered in South San Francisco, California, and founded in 2000,
CompareNetworks provides life scientists, researchers, lab-based professionals, pharmaceutical professionals and healthcare professionals
with digital tools and information resources to research, identify and determine which products and technologies to use.

       In January 2019, we fully exited our equity investment in Boss Industries, LLC ("Boss"). Boss markets, designs and manufacturers
vehicle-mounted, and portable air compressor and generator systems utilized in municipal and utility services, energy product and industrial
services. We realized a gain of approximately $4.0 million on the exit of our equity investment in Boss.

       During February 2019, we declared regular monthly dividends of $0.200 per share for each month of April, May and June 2019. These
regular monthly dividends equal a total of $0.600 per share for the second quarter of 2019 and represent a 5.3% increase from the dividends
declared for the second quarter of 2018. Including the dividends declared for the second quarter of 2019, we will have paid $25.420 per
share in cumulative dividends since our October 2007 initial public offering.

BUSINESS STRATEGIES

       Our principal investment objective is to maximize our portfolio's total return by generating current income from our debt investments
and capital appreciation from our equity and equity-related investments, including warrants, convertible securities and other rights to
acquire equity securities in a portfolio company. We have adopted the following business strategies to achieve our investment objective:

•

•

•

•

Deliver Customized Financing Solutions in the Lower Middle Market. We offer LMM portfolio companies
customized debt and equity financing solutions that are tailored to the facts and circumstances of each situation. We
believe our ability to provide a broad range of customized financing solutions to LMM companies sets us apart from
other capital providers that focus on providing a limited number of financing solutions. Our ability to invest across a
company's capital structure, from senior secured loans to subordinated debt to equity securities, allows us to offer
LMM portfolio companies a comprehensive suite of financing options, or a "one stop" financing solution. 

Focus on Established Companies. We generally invest in companies with established market positions, experienced
management teams and proven revenue streams. We believe that those companies generally possess better risk-
adjusted return profiles than newer companies that are building their management teams or are in the early stages of
building a revenue base. We also believe that established companies in our targeted size range also generally provide
opportunities for capital appreciation. 

Leverage the Skills and Experience of Our Investment Team. Our investment team has significant experience in
lending to and investing in LMM and Middle Market companies. The members of our investment team have broad
investment backgrounds, with prior experience at private investment funds, investment banks and other financial
services companies and currently include seven certified public accountants and three Chartered Financial Analyst®
charter holders. The expertise of our investment team in analyzing, valuing, structuring, negotiating and closing
transactions should provide us with competitive advantages by allowing us to consider customized financing
solutions and non-traditional or complex structures for our portfolio companies. Also, the reputation of our
investment team has and should continue to enable us to generate additional revenue in the form of management and
incentive fees in connection with us providing advisory services to other investment funds. 

Invest Across Multiple Companies, Industries, Regions and End Markets. We seek to maintain a portfolio of
investments that is appropriately balanced among various companies, industries, geographic regions and end markets.
This portfolio balance is intended to mitigate the potential effects of negative economic events for particular
companies, regions, industries and end markets.

Table of Contents

•

Capitalize on Strong Transaction Sourcing Network. Our investment team seeks to leverage its extensive network of
referral sources for portfolio company investments. We have developed a reputation in our marketplace as a
responsive, efficient and reliable source of financing, which has created a growing stream of proprietary deal flow for
us. 

Benefit from Lower, Fixed, Long-Term Cost of Capital. The SBIC licenses held by the Funds have allowed them to
issue SBA-guaranteed debentures. SBA-guaranteed debentures carry long-term fixed interest rates that are generally
lower than interest rates on comparable bank loans and other debt. Because lower-cost SBA leverage is, and will
continue to be, a significant part of our capital base through the Funds, our relative cost of debt capital should be
lower than many of our competitors. In addition, the SBIC leverage that we receive through the Funds represents a
stable, long-term component of our capital structure with proper matching of duration and cost compared to our
LMM portfolio investments. We also maintain an investment grade rating from Standard & Poor's Ratings Services
which provides us the opportunity and flexibility to obtain additional, attractive long-term financing options to
supplement our capital structure, including the unsecured notes with fixed interest rates we issued in 2014 and 2017.

INVESTMENT CRITERIA

       Our investment team has identified the following investment criteria that it believes are important in evaluating prospective portfolio
companies. Our investment team uses these criteria in evaluating investment opportunities. However, not all of these criteria have been, or
will be, met in connection with each of our investments:

•

•

•

•

Proven Management Team with Meaningful Equity Stake. We look for operationally-oriented management with
direct industry experience and a successful track record. In addition, we expect the management team of each LMM
portfolio company to have meaningful equity ownership in the portfolio company to better align our respective
economic interests. We believe management teams with these attributes are more likely to manage the companies in
a manner that both protects our debt investment and enhances the value of our equity investment. 

Established Companies with Positive Cash Flow.  We seek to invest in established companies with sound historical
financial performance. We typically focus on LMM companies that have historically generated EBITDA of
$3 million to $20 million and commensurate levels of free cash flow. We also pursue investments in debt securities
of Middle Market companies that are generally established companies with sound historical financial performance
that are generally larger in size than LMM companies. We generally do not invest in start-up companies or
companies with speculative business plans. 

Defensible Competitive Advantages/Favorable Industry Position. We primarily focus on companies having
competitive advantages in their respective markets and/or operating in industries with barriers to entry, which may
help to protect their market position and profitability. 

Exit Alternatives. We exit our debt investments primarily through the repayment of our investment from internally
generated cash flow of the portfolio company and/or a refinancing. In addition, we seek to invest in companies
whose business models and expected future cash flows may provide alternate methods of repaying our investment,
such as through a strategic acquisition by other industry participants or a recapitalization.

INVESTMENT PORTFOLIO

       The Investment Portfolio, as used herein, refers to all of our investments in LMM portfolio companies, investments in Middle Market
portfolio companies, Private Loan portfolio investments, Other Portfolio investments, and the investment in the External Investment
Manager. Our LMM portfolio investments primarily consist of secured debt, equity warrants and direct equity investments in privately
held, LMM

6

Table of Contents

companies based in the United States. Our Middle Market portfolio investments primarily consist of direct investments in or secondary
purchases of interest-bearing debt securities in privately held companies based in the United States that are generally larger in size than the
companies included in our LMM portfolio. Our Private Loan portfolio investments primarily consist of investments in interest-bearing debt
securities in companies that are consistent with the size of companies in our LMM portfolio or our Middle Market portfolio, but are
investments that we originate on a collaborative basis with other investment funds, and are often referred to in the debt markets as "club
deals." Our Other Portfolio investments primarily consist of investments which are not consistent with the typical profiles for our LMM,
Middle Market and Private Loan portfolio investments, including investments which may be managed by third parties. In our Other
Portfolio, we may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in other
investment companies or private funds.

Debt Investments

       Historically, we have made LMM debt investments principally in the form of single tranche debt. Single tranche debt financing
involves issuing one debt security that blends the risk and return profiles of both first lien secured and subordinated debt. We believe that
single tranche debt is more appropriate for many LMM companies given their size in order to reduce structural complexity and potential
conflicts among creditors.

       Our LMM debt investments generally have a term of five to seven years from the original investment date, with limited required
amortization prior to maturity, and provide for monthly or quarterly payment of interest at interest rates generally between 10% and 14%
per annum, payable currently in cash. Interest rate terms can include either fixed or floating rate terms. In addition, certain LMM debt
investments may have a form of interest that is not paid currently but is accrued and added to the loan balance and paid at maturity. We
refer to this form of interest as payment-in-kind, or PIK, interest. We typically structure our LMM debt investments with the maximum
seniority and collateral that we can reasonably obtain while seeking to achieve our total return target. In most cases, our LMM debt
investment will be collateralized by a first priority lien on substantially all the assets of the portfolio company. In addition to seeking a
senior lien position in the capital structure of our LMM portfolio companies, we seek to limit the downside potential of our LMM debt
investments by negotiating covenants that are designed to protect our LMM debt investments while affording our portfolio companies as
much flexibility in managing their businesses as is reasonable. Such restrictions may include affirmative and negative covenants, default
penalties, lien protection, change of control or change of management provisions, key-man life insurance, guarantees, equity pledges,
personal guaranties, where appropriate, and put rights. In addition, we typically seek board representation or observation rights in all of our
LMM portfolio companies. Interest rate terms can include either fixed or floating rate terms.

       While we will continue to focus our LMM debt investments primarily on single tranche debt investments, we also anticipate
structuring some of our debt investments as mezzanine loans. We anticipate that these mezzanine loans will be primarily junior secured or
unsecured, subordinated loans that provide for relatively high interest rates payable currently in cash that will provide us with significant
interest income plus the additional opportunity for income and gains through PIK interest and equity warrants and other similar equity
instruments issued in conjunction with these mezzanine loans. These loans typically will have interest-only payments in the early years,
with amortization of principal deferred to the later years of the mezzanine loan term. Typically, our mezzanine loans will have maturities of
three to five years. We will generally target interest rates of 12% to 14%, payable currently in cash for our mezzanine loan investments with
higher targeted total returns from equity warrants or PIK interest.

       We also pursue debt investments in Middle Market companies. Our Middle Market portfolio investments primarily consist of direct
investments or secondary purchases of interest-bearing debt securities in privately held companies based in the United States that are
generally larger in size than the companies included in our LMM portfolio. Our Middle Market portfolio debt investments are generally
secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven
years from the original investment date. The debt investments in our Middle Market portfolio have rights and protections that are similar to
those in our LMM debt investments, which may include affirmative

and negative covenants, default penalties, lien protection, change of control provisions, guarantees and equity pledges. The Middle Market
debt investments generally have floating interest rates at the London Interbank Offered Rate ("LIBOR") plus a margin, and are typically
subject to LIBOR floors.

       Our Private Loan portfolio investments primarily consist of investments in interest-bearing debt securities in companies that are
consistent with the size of companies in our LMM portfolio or our Middle Market portfolio, but are investments which have been
originated through strategic relationships with other investment funds on a collaborative basis. Our Private Loan portfolio debt investments
are generally secured by either a first or second priority lien and typically have a term of between three and seven years from the original
investment date.

Warrants

       In connection with our debt investments, we occasionally receive equity warrants to establish or increase our equity interest in the
portfolio company. Warrants we receive in connection with a debt investment typically require only a nominal cost to exercise, and thus, as
a portfolio company appreciates in value, we may achieve additional investment return from this equity interest. We typically structure the
warrants to provide provisions protecting our rights as a minority-interest holder, as well as secured or unsecured put rights, or rights to sell
such securities back to the portfolio company, upon the occurrence of specified events. In certain cases, we also may obtain registration
rights in connection with these equity interests, which may include demand and "piggyback" registration rights.

Direct Equity Investments

       We also will seek to make direct equity investments in situations where it is appropriate to align our interests with key management and
stockholders of our LMM portfolio companies, and to allow for participation in the appreciation in the equity values of our LMM portfolio
companies. We usually make our direct equity investments in connection with debt investments in our LMM portfolio companies. In
addition, we may have both equity warrants and direct equity positions in some of our LMM portfolio companies. We seek to maintain fully
diluted equity positions in our LMM portfolio companies of 5% to 50%, and may have controlling equity interests in some instances. We
have a value orientation toward our direct equity investments and have traditionally been able to purchase our equity investments at
reasonable valuations.

INVESTMENT PROCESS

       Our management team's investment committee is responsible for all aspects of our LMM investment process. The current members of
our investment committee are Dwayne L. Hyzak, our Chief Executive Officer and Senior Managing Director, David Magdol, our President,
Chief Investment Officer and Senior Managing Director, Vincent D. Foster, our Executive Chairman, and Curtis L. Hartman, our Vice-
Chairman, Chief Credit Officer and Senior Managing Director.

       Our management team's credit committee is responsible for all aspects of our Middle Market portfolio investment process. The current
members of our credit committee are Messrs. Hyzak, Foster, Hartman and Nicholas T. Meserve, Managing Director of our Middle Market
investment team.

       Investment process responsibility for each Private Loan portfolio investment is delegated to either the investment committee or the
credit committee based upon the nature of the investment and the manner in which it was originated. Similarly, the investment processes
for each Private Loan portfolio investment, from origination to close and to eventual exit, will follow the processes for our LMM portfolio
investments or our Middle Market portfolio investments as outlined below, or a combination thereof.

       Our investment strategy involves a "team" approach, whereby potential transactions are screened by several members of our
investment team before being presented to the investment committee or the credit

8

Table of Contents

committee, as applicable. Our investment committee and credit committee each meet on an as needed basis depending on transaction
volume. We generally categorize our investment process into seven distinct stages:

Deal Generation/Origination

       Deal generation and origination is maximized through long-standing and extensive relationships with industry contacts, brokers,
commercial and investment bankers, entrepreneurs, service providers such as lawyers, financial advisors and accountants, and current and
former portfolio companies and investors. Our investment team has focused its deal generation and origination efforts on LMM and Middle
Market companies, and we have developed a reputation as a knowledgeable, reliable and active source of capital and assistance in these
markets.

Screening

       During the screening process, if a transaction initially meets our investment criteria, we will perform preliminary due diligence, taking
into consideration some or all of the following information:

•

•

•

•

•

•

a comprehensive financial model based on quantitative analysis of historical financial performance, projections and pro
forma adjustments to determine the estimated internal rate of return; 

a brief industry and market analysis; 

direct industry expertise imported from other portfolio companies or investors; 

preliminary qualitative analysis of the management team's competencies and backgrounds; 

potential investment structures and pricing terms; and 

regulatory compliance.

       Upon successful screening of a proposed LMM transaction, the investment team makes a recommendation to our investment
committee. If our investment committee concurs with moving forward on the proposed LMM transaction, we typically issue a non-binding
term sheet to the company. For Middle Market portfolio investments, the initial term sheet is typically issued by the borrower, through the
syndicating bank, and is screened by the investment team which makes a recommendation to our credit committee.

Term Sheet

       For proposed LMM transactions, the non-binding term sheet will include the key economic terms based upon our analysis performed
during the screening process as well as a proposed timeline and our qualitative expectation for the transaction. While the term sheet for
LMM investments is non-binding, we typically receive an expense deposit in order to move the transaction to the due diligence phase.
Upon execution of a term sheet, we begin our formal due diligence process.

       For proposed Middle Market transactions, the initial term sheet will include key economic terms and other conditions proposed by the
borrower and its representatives and the proposed timeline for the investment, which are reviewed by our investment team to determine if
such terms and conditions are in agreement with our investment objectives.

Due Diligence

       Due diligence on a proposed LMM investment is performed by a minimum of two of our investment professionals, whom we refer to
collectively as the investment team, and certain external resources, who together conduct due diligence to understand the relationships
among the prospective portfolio company's

9

Table of Contents

business plan, operations and financial performance. Our LMM due diligence review includes some or all of the following:

•

•

•

•

•

•

•

•

•

site visits with management and key personnel; 

detailed review of historical and projected financial statements; 

operational reviews and analysis; 

interviews with customers and suppliers; 

detailed evaluation of company management, including background checks; 

review of material contracts; 

in-depth industry, market and strategy analysis; 

regulatory compliance analysis; and 

review by legal, environmental or other consultants, if applicable.

       Due diligence on a proposed Middle Market investment is generally performed on materials and information obtained from certain
external resources and assessed internally by a minimum of two of our investment professionals, who work to understand the relationships
among the prospective portfolio company's business plan, operations and financial performance using the accumulated due diligence
information. Our Middle Market due diligence review includes some or all of the following:

•

•

•

•

detailed review of historical and projected financial statements; 

in-depth industry, market, operational and strategy analysis; 

regulatory compliance analysis; and 

detailed review of the company's management team and their capabilities.

       During the due diligence process, significant attention is given to sensitivity analyses and how the company might be expected to
perform given downside, base-case and upside scenarios. In certain cases, we may decide not to make an investment based on the results of
the diligence process.

an analysis of historical financial results and key financial ratios.

       If any adjustments to the transaction terms or structures are proposed by the investment committee or credit committee, as applicable,
such changes are made and applicable analyses are updated prior to approval of the transaction. Approval for the transaction must be made
by the affirmative vote from a majority of the members of the investment committee or credit committee, as applicable, with the committee
member managing the transaction, if any, abstaining from the vote. Upon receipt of transaction approval, the investment team will re-
confirm regulatory compliance, process and finalize all required legal documents, and fund the investment.

Post-Investment

       We continuously monitor the status and progress of the portfolio companies. We generally offer managerial assistance to our portfolio
companies, giving them access to our investment experience, direct industry expertise and contacts. The same investment team that was
involved in the investment process will continue its involvement in the portfolio company post-investment. This provides for continuity of
knowledge and allows the investment team to maintain a strong business relationship with key management of our portfolio companies for
post-investment assistance and monitoring purposes.

       As part of the monitoring process of LMM portfolio investments, the investment team will analyze monthly and quarterly financial
statements versus the previous periods and year, review financial projections, meet and discuss issues or opportunities with management,
attend board meetings and review all compliance certificates and covenants. While we maintain limited involvement in the ordinary course
operations of our LMM portfolio companies, we maintain a higher level of involvement in non-ordinary course financing or strategic
activities and any non-performing scenarios. We also monitor the performance of our Middle Market portfolio investments; however, due
to the larger size and higher sophistication level of these Middle Market companies in comparison to our LMM portfolio companies, it is
not necessary or practical to have as much direct management interface.

       We utilize an internally developed investment rating system to rate the performance of each LMM portfolio company and to monitor
our expected level of returns on each of our LMM investments in relation to our expectations for the portfolio company. The investment
rating system takes into consideration various factors, including, but not limited to, each investment's expected level of returns, the
collectability of our debt investments and the ability to receive a return of the invested capital in our equity investments, comparisons to
competitors and other industry participants, the portfolio company's future outlook and other factors that are deemed to be significant to the
portfolio company.

Exit Strategies/Refinancing

       While we generally exit most investments through the refinancing or repayment of our debt and redemption or sale of our equity
positions, we typically assist our LMM portfolio companies in developing and planning exit opportunities, including any sale or merger of
our portfolio companies. We may also assist in the structure, timing, execution and transition of the exit strategy. The refinancing or
repayment of Middle Market debt investments typically does not require our assistance due to the additional resources available to these
larger, Middle Market companies.

DETERMINATION OF NET ASSET VALUE AND INVESTMENT PORTFOLIO VALUATION PROCESS

       We determine the net asset value per share of our common stock on a quarterly basis. The net asset value per share is equal to our total
assets minus total liabilities divided by the total number of shares of common stock outstanding.

       We are required to report our investments at fair value. As a result, the most significant determination inherent in the preparation of
our consolidated financial statements is the valuation of our Investment Portfolio and the related amounts of unrealized appreciation and
depreciation. We follow the provisions of the Financial Accounting Standards Board Accounting Standards Codification ("ASC") 820, Fair
Value Measurements and Disclosures ("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. ASC 820 requires us to assume that the portfolio investment is to be sold in the principal market to independent
market participants, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal market that
are independent, knowledgeable and willing and able to transact.

       We determine in good faith the fair value of our Investment Portfolio pursuant to a valuation policy in accordance with ASC 820 and a
valuation process approved by our Board of Directors and in accordance with the 1940 Act. Our valuation policies and processes are
intended to provide a consistent basis for determining the fair value of our Investment Portfolio. See "Note B.1. — Valuation of the
Investment Portfolio" in the notes to consolidated financial statements for a detailed discussion of our investment portfolio valuation
process and procedures.

       Due to the inherent uncertainty in the valuation process, our determination of fair value for our Investment Portfolio may differ
materially from the values that would have been determined had a ready market for the securities existed. In addition, 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 these investments to be materially different than the valuations currently assigned. We determine the fair
value of each individual investment and record changes in fair value as unrealized appreciation or depreciation.

       As described below, we undertake a multi-step valuation process each quarter in connection with determining the fair value of our
investments, with our Board of Directors having final responsibility for overseeing, reviewing and approving, in good faith, our
determination of the fair value for our Investment Portfolio and our valuation procedures, consistent with 1940 Act requirements. In
addition, the Audit Committee of our Board of Directors periodically evaluates the performance and methodologies of the financial
advisory services firm that we consult in connection with valuing our LMM and Private Loan portfolio company investments.

•

•

Our quarterly valuation process begins with each LMM and Private Loan portfolio company investment being
initially valued by the investment team responsible for monitoring the portfolio investment; 

The fair value determination for our Middle Market and Other Portfolio debt and equity investments and our
investment in the External Investment Manager consists of unobservable and observable inputs

which are initially reviewed by the investment professionals responsible for monitoring the portfolio investment;

Preliminary valuation conclusions are then reviewed by and discussed with senior management, and the investment
team considers and assesses, as appropriate, any changes that may be required to the preliminary valuations to
address any comments provided by senior management; 

A nationally recognized independent financial advisory services firm analyzes and provides observations,
recommendations and an assurance certification regarding the Company's determinations of the fair value for its
LMM and Private Loan portfolio companies; 

The Audit Committee of our Board of Directors reviews management's valuations, and the investment team and
senior management consider and assess, as appropriate, any changes that may be required to management's
valuations to address any comments provided by the Audit Committee; and 

The Board of Directors assesses the valuations and ultimately approves the fair value of each investment in our
portfolio in good faith.

•

•

•

       Determination of fair value involves subjective judgments and estimates. The notes to our consolidated financial statements refer to the
uncertainty with respect to the possible effect of such valuations, and any change in such valuations, on our financial results and financial
condition.

COMPETITION

       We compete for investments with a number of investment funds (including private equity funds, mezzanine funds, BDCs, and SBICs),
as well as traditional financial services companies such as commercial banks and other sources of financing. Many of the entities that
compete with us are larger and have more resources available to them. We believe we are able to be competitive with these entities
primarily on the basis of our focus toward the underserved LMM, the experience and contacts of our management team, our responsive and
efficient investment analysis and decision-making processes, our comprehensive suite of customized financing solutions and the
investment terms we offer.

       We believe that some of our competitors make senior secured loans, junior secured loans and subordinated debt investments with
interest rates and returns that are comparable to or lower than the rates and returns that we target. Therefore, we do not seek to compete
primarily on the interest rates and returns that we offer to potential portfolio companies. For additional information concerning the
competitive risks we face, see "Risk Factors — Risks Relating to Our Business and Structure — We may face increasing competition for
investment opportunities."

EMPLOYEES

       As of December 31, 2018, we had 66 employees. These employees include investment and portfolio management professionals,
operations professionals and administrative staff. As necessary, we will hire additional investment professionals and administrative
personnel. All of our employees are located in our Houston, Texas office.

REGULATION

Regulation as a Business Development Company

       We have elected to be regulated as a BDC under the 1940 Act. The 1940 Act contains prohibitions and restrictions relating to
transactions between BDCs and their affiliates, principal underwriters and affiliates of those affiliates or underwriters. The 1940 Act
requires that a majority of the members of the board of directors of a BDC be persons other than "interested persons," as that term is
defined in the 1940 Act. In addition, the 1940 Act provides that we may not change the nature of our business so as to cease to be, or to
withdraw our election as, a BDC unless approved by a majority of our outstanding voting securities.

13

Table of Contents

       The 1940 Act defines "a majority of the outstanding voting securities" as the lesser of (i) 67% or more of the voting securities present
at a meeting if the holders of more than 50% of our outstanding voting securities are present or represented by proxy or (ii) more than 50%
of our outstanding voting securities.

Qualifying Assets

       Under the 1940 Act, a BDC may not acquire any asset other than assets of the type listed in Section 55(a) of the 1940 Act, which are
referred to as qualifying assets, unless, at the time the acquisition is made, qualifying assets represent at least 70% of the company's total
assets. The principal categories of qualifying assets relevant to our business are any of the following:

(1)

(2)

(3)

(4)

(5)

(6)

Securities purchased in transactions not involving any public offering from the issuer of such securities, which issuer
(subject to certain limited exceptions) is an eligible portfolio company (as defined below), or from any person who is, or has
been during the preceding 13 months, an affiliated person of an eligible portfolio company, or from any other person, subject
to such rules as may be prescribed by the SEC. 

Securities of any eligible portfolio company that we control. 

Securities purchased in a private transaction from a U.S. issuer that is not an investment company or from an affiliated
person of the issuer, or in transactions incident thereto, if the issuer is in bankruptcy and subject to reorganization or if the
issuer, immediately prior to the purchase of its securities was unable to meet its obligations as they came due without
material assistance other than conventional lending or financing arrangements. 

Securities of an eligible portfolio company purchased from any person in a private transaction if there is no ready market for
such securities and we already own 60% of the outstanding equity of the eligible portfolio company. 

Securities received in exchange for or distributed on or with respect to securities described in (1) through (4) above, or
pursuant to the exercise of warrants or rights relating to such securities. 

Cash, cash equivalents, U.S. government securities or high-quality debt securities maturing in one year or less from the time
of investment.

       In addition, a BDC must have been organized and have its principal place of business in the United States and must be operated for the
purpose of making investments in the types of securities described in (1), (2) or (3) above.

       An eligible portfolio company is defined in the 1940 Act as any issuer which:

(a)

(b)

(c)

is organized under the laws of, and has its principal place of business in, the United States; 

is not an investment company (other than a small business investment company wholly owned by the BDC) or a company
that would be an investment company but for certain exclusions under the 1940 Act; and 

satisfies any of the following: 

(i)

(ii)

(iii)

does not have any class of securities that is traded on a national securities exchange or has a class of securities listed
on a national securities exchange but has an aggregate market value of outstanding voting and non-voting common
equity of less than $250 million; 

is controlled by a BDC or a group of companies including a BDC and the BDC has an affiliated person who is a
director of the eligible portfolio company; or 

is a small and solvent company having total assets of not more than $4 million and capital and surplus of not less
than $2 million.

14

Table of Contents

Managerial Assistance to Portfolio Companies

       As noted above, a BDC must be operated for the purpose of making investments in the type of securities described in (1), (2) or
(3) above under the heading entitled "— Qualifying Assets." In addition, BDCs must generally offer to make available to such issuer of the
securities (other than small and solvent companies described above) significant managerial assistance; except that, where we purchase such
securities in conjunction with one or more other persons acting together, one of the other persons in the group may make available such
managerial assistance. Making available managerial assistance means, among other things, any arrangement whereby the BDC, through its
directors, officers or employees, offers to provide, and, if accepted, does so provide, significant guidance and counsel concerning the
management, operations or business objectives and policies of a portfolio company.

Temporary Investments

       Pending investment in "qualifying assets," as described above, our investments may consist of cash, cash equivalents, U.S. government
securities and high-quality debt securities maturing in one year or less from time of investment therein, so that 70% of our assets are
qualifying assets.

Senior Securities

       Under the provisions of the 1940 Act, we are permitted, as a BDC, to issue senior securities only in amounts such that our asset
coverage, as defined in the 1940 Act, equals at least 200% of all debt and/or senior stock immediately after each such issuance. However,
recent legislation has modified the 1940 Act by allowing a BDC to increase the maximum amount of leverage it may incur from an asset
coverage ratio of 200% to an asset coverage ratio of 150%, if certain requirements are met. We are permitted to increase our leverage
capacity if stockholders representing at least a majority of the votes cast, when quorum is met, approve a proposal to do so. If we receive
such stockholder approval, we would be permitted to increase our leverage capacity on the first day after such approval. Alternatively, we
may increase the maximum amount of leverage we may incur to an asset coverage ratio of 150% if the "required majority" of our
independent directors as defined in Section 57(o) of the 1940 Act approve such increase with such approval becoming effective after one
year. In either case, we would be required to make certain disclosures on our website and in SEC filings regarding, among other things, the
receipt of approval to increase our leverage, our leverage capacity and usage, and risks related to leverage. In addition, while any senior
securities remain outstanding (other than senior securities representing indebtedness issued in consideration of a privately arranged loan
which is not intended to be publicly distributed), we must make provisions to prohibit any distribution to our stockholders or the repurchase
of such securities or shares unless we meet the applicable asset coverage ratios at the time of the distribution or repurchase. We may also
borrow amounts up to 5% of the value of our total assets for temporary or emergency purposes without regard to asset coverage. For a
discussion of the risks associated with leverage, see "Risk Factors — Risks Relating to Our Business and Structure," including, without
limitation, "— Because we borrow money, the potential for gain or loss on amounts invested in us is magnified and may increase the risk
of investing in us."

       We have previously received an exemptive order from the SEC to exclude debt securities issued by MSMF and any other wholly
owned subsidiaries of ours which operate as SBICs from the asset coverage requirements of the 1940 Act as applicable to Main Street. The
exemptive order provides for the exclusion of all debt securities issued by the Funds, including the $345.8 million of outstanding debt as of
December 31, 2018, issued pursuant to the SBIC program. This exemptive order provides us with expanded capacity and flexibility in
obtaining future sources of capital for our investment and operational objectives.

Common Stock

       We are not generally able to issue and sell our common stock at a price below net asset value per share. We may, however, sell our
common stock, warrants, options or rights to acquire our common stock, at a price below the current net asset value of the common stock if
our Board of Directors determines that such sale is

15

Table of Contents

in our best interests and that of our stockholders, and our stockholders approve such sale. In any such case, the price at which our securities
are to be issued and sold may not be less than a price which, in the determination of our Board of Directors, closely approximates the
market value of such securities (less any distributing commission or discount). We did not seek stockholder authorization to sell shares of
our common stock below the then current net asset value per share of our common stock at our 2018 annual meeting of stockholders
because our common stock price had been trading significantly above the net asset value per share of our common stock since 2011. Our
stockholders have previously approved a proposal that authorizes us to issue securities to subscribe to, convert to, or purchase shares of our
common stock in one or more offerings. We may also make rights offerings to our stockholders at prices per share less than the net asset
value per share, subject to applicable requirements of the 1940 Act. See "Risk Factors — Risks Relating to Our Business and Structure —
Stockholders may incur dilution if we sell shares of our common stock in one or more offerings at prices below the then current net asset
value per share of our common stock or issue securities to subscribe to, convert to or purchase shares of our common stock."

Code of Ethics

       We have adopted a code of ethics pursuant to Rule 17j-1 under the 1940 Act that establishes procedures for personal investments and
restricts certain personal securities transactions. Personnel subject to the code may invest in securities for their personal investment
accounts, including securities that may be purchased or held by us, so long as such investments are made in accordance with the code's
requirements. In addition, the code of ethics is available on the EDGAR Database on the SEC's Web site at http://www.sec.gov.

Proxy Voting Policies and Procedures

       We vote proxies relating to our portfolio securities in a manner in which we believe is consistent with the best interest of our
stockholders. We review on a case-by-case basis each proposal submitted to a stockholder vote to determine its impact on the portfolio
securities held by us. Although we generally vote against proposals that we expect would have a negative impact on our portfolio
securities, we may vote for such a proposal if there exists compelling long-term reasons to do so.

       Our proxy voting decisions are made by the investment team which is responsible for monitoring each of our investments. To ensure
that our vote is not the product of a conflict of interest, we require that anyone involved in the decision-making process discloses to our
chief compliance officer any potential conflict regarding a proxy vote of which he or she is aware.

       Stockholders may obtain information, without charge, regarding how we voted proxies with respect to our portfolio securities by
making a written request for proxy voting information to: Chief Compliance Officer, 1300 Post Oak Boulevard, 8th Floor, Houston, Texas
77056.

Other 1940 Act Regulations

       We are also prohibited under the 1940 Act from knowingly participating in certain transactions with our affiliates without the prior
approval of our Board of Directors who are not interested persons and, in some cases, prior approval by the SEC.

       We are required to provide and maintain a bond issued by a reputable fidelity insurance company to protect us against larceny and
embezzlement. Furthermore, as a BDC, we are prohibited from protecting any director or officer against any liability to us or our
stockholders arising from willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of
such person's office.

       We are required to adopt and implement written policies and procedures reasonably designed to prevent violation of the federal
securities laws, review these policies and procedures no less frequently than annually for their adequacy and the effectiveness of their
implementation, and to designate a chief compliance officer to be responsible for administering the policies and procedures.

       We may be periodically examined by the SEC for compliance with the 1940 Act.

Small Business Investment Company Regulations

       Each of the Funds is licensed by the SBA to operate as a SBIC under Section 301(c) of the Small Business Investment Act of 1958.
MSMF obtained its SBIC license in 2002, MSC II obtained its license in 2006 and MSC III obtained its license in 2016.

       SBICs are designed to stimulate the flow of private capital to eligible small businesses. Under SBIC regulations, SBICs may make
loans to eligible small businesses, invest in the equity securities of such businesses and provide them with consulting and advisory services.
Each of the Funds has typically invested in secured debt, acquired warrants and/or made equity investments in qualifying small businesses.

       The Funds are subject to regulation and oversight by the SBA, including requirements with respect to reporting financial information,
such as the extent of capital impairment if applicable, on a regular basis and annual examinations conducted by the SBA. The SBA, as a
creditor, will have a superior claim to the Funds' assets over our securities holders in the event the Funds are liquidated or the SBA
exercises its remedies under the SBA-guaranteed debentures issued by the Funds upon an event of default.

       We have received exemptive relief from the SEC to permit us to exclude the SBA-guaranteed debentures of the Funds from our 200%
asset coverage test under the 1940 Act. As such, our ratio of total consolidated assets to outstanding indebtedness may be less than 200%.
This provides us with increased investment flexibility but also increases our risks related to leverage. See "Risk Factors — Risks Relating
to Our Business and Structure — Because we borrow money, the potential for gain or loss on amounts invested in us is magnified and may
increase the risk of investing in us."

       Under present SBIC regulations, eligible small businesses generally include businesses that (together with their affiliates) have a
tangible net worth not exceeding $19.5 million or have average annual net income after U.S. federal income taxes not exceeding
$6.5 million (average net income to be computed without benefit of any carryover loss) for the two most recent fiscal years. In addition, an
SBIC must devote 25% of its investment activity to "smaller" enterprises as defined by the SBA. A smaller enterprise generally includes
businesses that have a tangible net worth not exceeding $6 million and have average annual net income after U.S. federal income taxes not
exceeding $2 million (average net income to be computed without benefit of any net carryover loss) for the two most recent fiscal years.
SBIC regulations also provide alternative size standard criteria to determine eligibility for designation as an eligible small business or
smaller enterprise, which criteria depend on the primary industry in which the business is engaged and are based on such factors as the
number of employees and gross revenue. However, once an SBIC has invested in a company, it generally may continue to make follow-on
investments in the company, regardless of the size of the portfolio company at the time of the follow-on investment, up to the time of the
portfolio company's initial public offering.

       The SBA prohibits an SBIC from providing funds to small businesses for certain purposes, such as relending and investment outside
the United States, to businesses engaged in certain prohibited industries, and to certain "passive" (non-operating) companies. In addition,
without prior SBA approval, an SBIC may not invest an amount equal to more than approximately 30% of the SBIC's regulatory capital, as
defined by the SBA, in any one portfolio company and its affiliates.

       The SBA places certain limitations on the financing terms of investments by SBICs in portfolio companies (such as limiting the
permissible interest rate on debt securities held by an SBIC in a portfolio company). Included in such limitations are SBA regulations which
allow an SBIC to exercise control over a small business for a period of seven years from the date on which the SBIC initially acquires its
control position. This control period may be extended for an additional period of time with the SBA's prior written approval.

       The SBA restricts the ability of an SBIC to lend money to any of its officers, directors and employees or to invest in affiliates thereof.
The SBA also prohibits, without prior SBA approval, a "change of control" of an SBIC or transfers that would result in any person (or a
group of persons acting in concert) owning 10% or more of a class of equity of a licensed SBIC. A "change of control" is any event which
would result in the

17

Table of Contents

transfer of the power, direct or indirect, to direct the management and policies of an SBIC, whether through ownership, contractual
arrangements or otherwise.

       The SBIC licenses allow the Funds to incur leverage by issuing SBA-guaranteed debentures, subject to the issuance of a capital
commitment and certain approvals by the SBA and customary procedures. SBA-guaranteed debentures carry long-term fixed rates that are
generally lower than rates on comparable bank and other debt. Under applicable regulations, an SBIC may generally have outstanding
debentures guaranteed by the SBA in amounts up to twice the amount of the privately raised funds of the SBIC. Debentures guaranteed by
the SBA have a maturity of ten years, require semiannual payments of interest, do not require any principal payments prior to maturity, and
are not subject to prepayment penalties. As of December 31, 2018, we, through the Funds, had $345.8 million of outstanding SBA-
guaranteed debentures, which had an annual weighted-average interest rate of approximately 3.7%.

       SBICs must invest idle funds that are not being used to make loans in investments permitted under SBIC regulations in the following
limited types of securities: (i) direct obligations of, or obligations guaranteed as to principal and interest by, the United States government,
which mature within 15 months from the date of the investment; (ii) repurchase agreements with federally insured institutions with a
maturity of seven days or less (and the securities underlying the repurchase obligations must be direct obligations of or guaranteed by the
federal government); (iii) certificates of deposit with a maturity of one year or less, issued by a federally insured institution; (iv) a deposit
account in a federally insured institution that is subject to a withdrawal restriction of one year or less; (v) a checking account in a federally
insured institution; or (vi) a reasonable petty cash fund.

       SBICs are periodically examined and audited by the SBA's staff to determine their compliance with SBIC regulations and are
periodically required to file certain financial information and other documents with the SBA.

       Neither the SBA nor the U.S. government or any of its agencies or officers has approved any ownership interest to be issued by us or
any obligation that we or any of our subsidiaries may incur.

Securities Exchange Act of 1934 and Sarbanes-Oxley Act Compliance

       We are subject to the reporting and disclosure requirements of the Securities Exchange Act of 1934 (the "Exchange Act"), including
the filing of quarterly, annual and current reports, proxy statements and other required items. In addition, we are subject to the Sarbanes-
Oxley Act of 2002, which imposes a wide variety of regulatory requirements on publicly-held companies and their insiders. For example:

•

•

•

•

pursuant to Rule 13a-14 of the Exchange Act, our Chief Executive Officer and Chief Financial Officer are required
to certify the accuracy of the consolidated financial statements contained in our periodic reports; 

pursuant to Item 307 of Regulation S-K, our periodic reports are required to disclose our conclusions about the
effectiveness of our disclosure controls and procedures; 

pursuant to Rule 13a-15 of the Exchange Act, our management is required to prepare a report regarding its
assessment of our internal control over financial reporting, and our independent registered public accounting firm
separately audits our internal control over financial reporting; and 

pursuant to Item 308 of Regulation S-K and Rule 13a-15 of the Exchange Act, our periodic reports must disclose
whether there were significant changes in our internal control over financial reporting or in other factors that could
significantly affect these controls subsequent to the date of their evaluation, including any corrective actions with
regard to significant deficiencies and material weaknesses.

The New York Stock Exchange Corporate Governance Regulations

       The New York Stock Exchange ("NYSE") has adopted corporate governance regulations that listed companies must comply with. We
believe we are in compliance with such corporate governance listing

18

Table of Contents

standards. We intend to monitor our compliance with all future listing standards and to take all necessary actions to ensure that we stay in
compliance.

Investment Adviser Regulations

       The External Investment Manager, which is wholly owned by us, is subject to regulation under the Advisers Act. The Advisers Act
establishes, among other things, recordkeeping and reporting requirements, disclosure requirements, limitations on transactions between
the adviser's account and an advisory client's account, limitations on transactions between the accounts of advisory clients, and general anti-
fraud prohibitions. The External Investment Manager may be examined by the SEC from time to time for compliance with the Advisers
Act.

Taxation as a Regulated Investment Company

       MSCC has elected to be treated for U.S. federal income tax purposes as a RIC under Subchapter M of the Code. MSCC's taxable
income includes the taxable income generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as
disregarded entities for tax purposes. As a RIC, we generally will not pay corporate-level U.S. federal income taxes on any income that we
distribute to our stockholders as dividends. To qualify as a RIC, we must, among other things, meet certain source-of-income and asset
diversification requirements (as described below). In addition, in order to obtain RIC tax treatment, we must distribute to our stockholders,
for each taxable year, at least 90% of our "investment company taxable income," which is generally our net ordinary taxable income plus
the excess of realized net short-term capital gains over realized net long-term capital losses, and 90% of our tax-exempt income (the
"Annual Distribution Requirement"). As part of maintaining RIC status, undistributed taxable income (subject to a 4% non-deductible U.S.
federal excise tax) pertaining to a given fiscal year may be distributed up to 12 months subsequent to the end of that fiscal year, provided
such dividends are declared on or prior to the later of (i) filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the
fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

       For any taxable year in which we qualify as a RIC and satisfy the Annual Distribution Requirement, we will not be subject to U.S.
federal income tax on the portion of our income or capital gains we distribute (or are deemed to distribute) to stockholders. We will be
subject to U.S. federal income tax at the regular corporate rates on any income or capital gains not distributed (or deemed distributed) to our
stockholders.

       We are subject to a 4% non-deductible U.S. federal excise tax on certain undistributed income unless we distribute in a timely manner
an amount at least equal to the sum of (1) 98% of our net ordinary taxable income for each calendar year, (2) 98.2% of our capital gain net
income for the one-year period ending December 31 in that calendar year and (3) any taxable income recognized, but not distributed, in
preceding years on which we paid no U.S. federal income tax (the "Excise Tax Avoidance Requirement"). Dividends declared and paid by
us in a year will generally differ from taxable income for that year as such dividends may include the distribution of current year taxable
income, exclude amounts carried over into the following year, and include the distribution of prior year taxable income carried over into
and distributed in the current year. For amounts we carry over into the following year, we will be required to pay the 4% U.S. federal
excise tax on the excess of 98% of our annual investment company taxable income and 98.2% of our capital gain net income over our
distributions for the year.

       In order to qualify as a RIC for U.S. federal income tax purposes, we must, among other things:

•

•

continue to qualify as a BDC under the 1940 Act at all times during each taxable year; 

derive in each taxable year at least 90% of our gross income from dividends, interest, payments with respect to
certain securities, loans, gains from the sale of stock or other securities, net income from certain "qualified publicly
traded partnerships," or other income derived with respect to our business of investing in such stock or securities (the
"90% Income Test"); and

19

Table of Contents

•

diversify our holdings so that at the end of each quarter of the taxable year: 

•

•

at least 50% of the value of our assets consists of cash, cash equivalents, U.S. government securities,
securities of other RICs, and other securities if such other securities of any one issuer do not represent more
than 5% of the value of our assets or more than 10% of the outstanding voting securities of the issuer; and 

no more than 25% of the value of our assets is invested in the securities, other than U.S. government
securities or securities of other RICs, (i) of one issuer, (ii) of two or more issuers that are controlled, as
determined under applicable Code rules, by us and that are engaged in the same or similar or related trades
or businesses or (iii) of certain "qualified publicly traded partnerships" (collectively, the "Diversification
Tests").

       In order to comply with the 90% Income Test, we formed the Taxable Subsidiaries as wholly owned taxable subsidiaries for the
primary purpose of permitting us to own equity interests in portfolio companies which are "pass-through" entities for tax purposes. Absent
the taxable status of the Taxable Subsidiaries, a portion of the gross income from such portfolio companies would flow directly to us for
purposes of the 90% Income Test. To the extent such income did not consist of income derived from securities, such as dividends and
interest, it could jeopardize our ability to qualify as a RIC and, therefore, cause us to incur significant U.S. federal income taxes. The
Taxable Subsidiaries are consolidated with Main Street for generally accepted accounting principles in the United States of America
("U.S. GAAP") purposes and are included in our consolidated financial statements, and the portfolio investments held by the Taxable
Subsidiaries are included in our consolidated financial statements. The Taxable Subsidiaries are not consolidated with Main Street for
income tax purposes and may generate income tax expense, or benefit, as a result of their ownership of the portfolio investments. The
income tax expense, or benefit, if any, and any related tax assets and liabilities, are reflected in our consolidated financial statements.

       The External Investment Manager is accounted for as a portfolio investment for U.S. GAAP purposes and is an indirect wholly owned
subsidiary of MSCC, owned through a Taxable Subsidiary. The External Investment Manager is owned by a Taxable Subsidiary in order to
comply with the 90% Income Test, since the External Investment Manager's income would likely not consist of income derived from
securities, such as dividends and interest, and as result, it could jeopardize our ability to qualify as a RIC and, therefore, cause us to incur
significant U.S. federal income taxes. As a result of its ownership by a Taxable Subsidiary, the External Investment Manager is a
disregarded entity for tax purposes. The External Investment Manager has also entered into a tax sharing agreement with its Taxable
Subsidiary owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a
consolidated subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its
Taxable Subsidiary owner, for its stand-alone financial reporting purposes the External Investment Manager is treated as if it is taxed at
normal corporate tax rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. The
income tax expense, or benefit, if any, and the related tax assets and liabilities, of the External Investment Manager are reflected in the
External Investment Manager's separate financial statements.

       We may be required to recognize taxable income in circumstances in which we do not receive cash. For example, if we hold debt
obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments issued with warrants and
debt securities invested in at a discount to par), we must include in income each year a portion of the original issue discount that accrues
over the life of the obligation, regardless of whether cash representing such income is received by us in the same taxable year. We may
also have to include in income other amounts that we have not yet received in cash such as PIK interest, cumulative dividends or amounts
that are received in non-cash compensation such as warrants or stock. Because any original issue discount or other amounts accrued will be
included in our investment company taxable income for the year of accrual, we may be required to make a distribution to our stockholders
in order to satisfy the Annual Distribution Requirement, even though we will not have received any corresponding cash amount.

20

Table of Contents

       Although we do not presently expect to do so, we are authorized to borrow funds and to sell assets in order to satisfy distribution
requirements. However, under the 1940 Act, we are not permitted to make distributions to our stockholders in certain circumstances while
our debt obligations and other senior securities are outstanding unless certain "asset coverage" tests are met. See "Regulation — Regulation
as a Business Development Company — Senior Securities." Moreover, our ability to dispose of assets to meet our distribution requirements
may be limited by (1) the illiquid nature of our portfolio and/or (2) other requirements relating to our status as a RIC, including the
Diversification Tests. If we dispose of assets in order to meet the Annual Distribution Requirement or the Excise Tax Avoidance
Requirement, we may make such dispositions at times that, from an investment standpoint, are not advantageous.

       We may distribute taxable dividends that are payable in part in our stock. Under certain applicable provisions of the Code and the U.S.
Department of the Treasury ("Treasury") regulations, distributions payable by us in cash or in shares of stock (at the stockholders election)
would satisfy the Annual Distribution Requirement. The Internal Revenue Service has issued guidance indicating that this rule will apply
even where the total amount of cash that may be distributed is limited to no more than 20% of the total distribution. According to this
guidance, if too many stockholders elect to receive their distributions in cash, each such stockholder would receive a pro rata share of the
total cash to be distributed and would receive the remainder of their distribution in shares of stock. Taxable stockholders receiving such
dividends will be required to include the full amount of the dividend (whether received in cash, our stock, or a combination thereof) as
(i) ordinary income (including any qualified dividend income that, in the case of a noncorporate stockholder, may be eligible for the same
reduced maximum tax rate applicable to long-term capital gains to the extent such distribution is properly reported by us as qualified
dividend income and such stockholder satisfies certain minimum holding period requirements with respect to our stock) or (ii) long-term
capital gain (to the extent such distribution is properly reported as a capital gain dividend), to the extent of our current and accumulated
earnings and profits for U.S. federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such
dividends in excess of any cash received. If a U.S. stockholder sells the stock it receives in order to pay this tax, the sales proceeds may be
less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale.
Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in
respect of all or a portion of such dividend that is payable in stock. In addition, if a significant number of our stockholders determine to sell
shares of our stock in order to pay taxes owed on dividends, it may put downward pressure on the trading price of our stock.

Failure to Qualify as a RIC

       If we fail to satisfy the 90% Income Test or the Diversification Tests for any taxable year, we may nevertheless continue to qualify as a
RIC for such year if certain relief provisions are applicable (which may, among other things, require us to pay certain corporate-level U.S.
federal taxes or to dispose of certain assets).

       If we were unable to qualify for treatment as a RIC and the foregoing relief provisions are not applicable, we would be subject to tax on
all of our taxable income at regular corporate rates. We would not be able to deduct distributions to stockholders, nor would they be
required to be made. If we were subject to tax on all of our taxable income at regular corporate rates, then distributions we make after being
subject to such tax would be taxable to our stockholders and, provided certain holding period and other requirements were met, could
qualify for treatment as "qualified dividend income" eligible for the maximum 20% rate (plus a 3.8% Medicare surtax, if applicable)
applicable to qualified dividends to the extent of our current and accumulated earnings and profits. Subject to certain limitations under the
Code, corporate taxpayers would be eligible for a dividends-received deduction on distributions they receive. Distributions in excess of our
current and accumulated earnings and profits would be treated first as a return of capital to the extent of the stockholder's tax basis, and any
remaining distributions would be treated as a capital gain. To requalify as a RIC in a subsequent taxable year, we would be required to
satisfy the RIC qualification requirements for that year and dispose of any earnings and profits from any year in which we failed to qualify
as a RIC. Subject to a

21

Table of Contents

limited exception applicable to RICs that qualified as such under Subchapter M of the Code for at least one year prior to disqualification
and that requalify as a RIC no later than the second year following the nonqualifying year, we could be subject to tax on any unrealized net
built-in gains in the assets held by us during the period in which we failed to qualify as a RIC that are recognized within the subsequent five
years, unless we made a special election to pay corporate-level U.S. federal income tax on such built-in gain at the time of our
requalification as a RIC.

Item 1A.    Risk Factors 

       Investing in our securities involves a number of significant risks. In addition to the other information contained in this Annual Report
on Form 10-K, you should consider carefully the following information before making an investment in our securities. The risks set out
below are not the only risks we face. Additional risks and uncertainties not presently known to us or not presently deemed material by us
might also impair our operations and performance. If any of the following events occur, our business, financial condition and results of
operations could be materially and adversely affected. In such case, our net asset value, the trading price of our common stock and the
value of our other securities could decline, and you may lose all or part of your investment.

RISKS RELATING TO ECONOMIC CONDITIONS

Deterioration in the economy and financial markets increases the likelihood of adverse effects on our financial position and
results of operations. Such economic adversity could impair our portfolio companies' financial positions and operating results
and affect the industries in which we invest, which could, in turn, harm our operating results.

       The broader fundamentals of the United States economy remain mixed. In the event that the United States economy contracts, it is
likely that the financial results of small to mid-sized companies, like those in which we invest, could experience deterioration or limited
growth from current levels, which could ultimately lead to difficulty in meeting their debt service requirements and an increase in defaults.
In addition, a decline in oil and natural gas prices would adversely affect the credit quality of our debt investments and the underlying
operating performance of our equity investments in energy-related businesses. Consequently, we can provide no assurance that the
performance of certain portfolio companies will not be negatively impacted by economic cycles, industry cycles or other conditions, which
could also have a negative impact on our future results.

       Although we have been able to secure access to additional liquidity, including through our multi-year revolving credit facility (the
"Credit Facility"), public debt issuances, leverage available through the SBIC program and equity offerings, the potential for volatility in
the debt and equity capital markets provides no assurance that debt or equity capital will be available to us in the future on favorable terms,
or at all. Further, if the price of our common stock falls below our net asset value per share, we will be limited in our ability to sell new
shares if we do not have stockholder authorization to sell shares at a price below net asset value per share. We did not seek stockholder
authorization to sell shares of our common stock below the then current net asset value per share of our common stock at our 2018 annual
meeting of stockholders because our common stock price had been trading significantly above the net asset value per share of our common
stock since 2011.

Global capital markets could enter a period of severe disruption and instability. These conditions have historically affected and
could again materially and adversely affect debt and equity capital markets in the United States, which could have a materially
negative impact on our business, financial condition and results of operations.

       The U.S. and global capital markets have, from time to time, experienced periods of disruption characterized by the freezing of
available credit, a lack of liquidity in the debt capital markets, significant losses in the principal value of investments, the re-pricing of
credit risk in the broadly syndicated credit

22

Table of Contents

market, the failure of major financial institutions and general volatility in the financial markets. During these periods of disruption, general
economic conditions deteriorated with material and adverse consequences for the broader financial and credit markets, and the availability
of debt and equity capital for the market as a whole, and financial services firms in particular, was reduced significantly. These conditions
may reoccur for a prolonged period of time or materially worsen in the future. In addition, continuing uncertainty arising from the United
Kingdom's decision to leave the European Union (the so called "Brexit") could lead to further market disruptions and currency volatility,
potentially weakening consumer, corporate and financial confidence and resulting in lower economic growth for companies that rely
significantly on Europe for their business activities and revenues. We may in the future have difficulty accessing debt and equity capital
markets, and a severe disruption in the global financial markets, deterioration in credit and financing conditions or uncertainty regarding
U.S. government spending and deficit levels, Brexit or other global economic conditions could have a material adverse effect on our
business, financial condition and results of operations.

RISKS RELATING TO OUR BUSINESS AND STRUCTURE

Our Investment Portfolio is and will continue to be recorded at fair value, with our Board of Directors having final responsibility
for overseeing, reviewing and approving, in good faith, our determination of fair value and, as a result, there is and will
continue to be uncertainty as to the value of our portfolio investments.

       Under the 1940 Act, we are required to carry our portfolio investments at market value or, if there is no readily available market value,
at fair value as determined by us with our Board of Directors having final responsibility for overseeing, reviewing and approving, in good
faith, our determination of fair value and our valuation procedures. Typically, there is not a public market for the securities of the privately
held LMM or Private Loan companies in which we have invested and will generally continue to invest. As a result, we value these
securities quarterly at fair value based on inputs from management, a nationally recognized independent financial advisory services firm
(on a rotational basis) and our audit committee with the oversight, review and approval of our Board of Directors. In addition, the market
for investments in Middle Market companies is generally not a liquid market, and therefore, we primarily use a combination of observable
inputs in non-active markets for which sufficient observable inputs were not available to determine the fair value of these investments and
unobservable inputs, which are reviewed by our audit committee with the oversight, review and approval of our Board of Directors. See
"Note B.1. — Valuation of the Investment Portfolio" in the notes to consolidated financial statements for a more detailed description of our
investment portfolio valuation process and procedures.

       The determination of fair value and consequently, the amount of unrealized gains and losses in our portfolio, are to a certain degree,
subjective and dependent on a valuation process approved by our Board of Directors. Certain factors that may be considered in determining
the fair value of our investments include external events, such as private mergers, sales and acquisitions involving comparable companies.
Because such valuations, and particularly valuations of securities in privately held companies, are inherently uncertain, may fluctuate over
short periods of time and may be based on estimates, our determinations of fair value may differ materially from the values that would have
been used if a ready market for these securities existed. Due to this uncertainty, our fair value determinations may cause our net asset value
on a given date to materially understate or overstate the value that we may ultimately realize on one or more of our investments. As a result,
investors purchasing our securities based on an overstated net asset value would pay a higher price than the value of our investments might
warrant. Conversely, investors selling our securities during a period in which the net asset value understates the value of our investments
may receive a lower price for their securities than the value of our investments might warrant.

23

Table of Contents

Our financial condition and results of operations depends on our ability to effectively manage and deploy capital.

       Our ability to achieve our investment objective of maximizing our portfolio's total return by generating current income from our debt
investments and capital appreciation from our equity and equity-related investments, including warrants, convertible securities and other
rights to acquire equity securities in a portfolio company, depends on our ability to effectively manage and deploy capital, which depends, in
turn, on our investment team's ability to identify, evaluate and monitor, and our ability to finance and invest in, companies that meet our
investment criteria.

       Accomplishing our investment objective on a cost-effective basis is largely a function of our investment team's handling of the
investment process, its ability to provide competent, attentive and efficient services and our access to investments offering acceptable
terms. In addition to monitoring the performance of our existing investments, members of our investment team are also called upon, from
time to time, to provide managerial assistance to some of our portfolio companies. These demands on their time may distract them or slow
the rate of investment.

       Even if we are able to grow and build upon our investment operations, any failure to manage our growth effectively could have a
material adverse effect on our business, financial condition, results of operations and prospects. The results of our operations will depend
on many factors, including the availability of opportunities for investment, readily accessible short and long-term funding alternatives in the
financial markets and economic conditions. Furthermore, if we cannot successfully operate our business or implement our investment
policies and strategies as described herein, it could negatively impact our ability to pay dividends.

We may face increasing competition for investment opportunities.

       We compete for investments with other investment funds (including private equity funds, debt funds, mezzanine funds, collateralized
loan obligation funds, or CLOs, BDCs, and SBICs), as well as traditional financial services companies such as commercial banks and other
sources of funding. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing
resources than we do. For example, some competitors may have a lower cost of capital and access to funding sources that are not available
to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments than we have. These
characteristics could allow our competitors to consider a wider variety of investments, establish more relationships and offer better pricing
and more flexible structuring than we are able to do. We may lose investment opportunities if we do not match our competitors' pricing,
terms and structure. If we are forced to match our competitors' pricing, terms and structure, we may not be able to achieve acceptable
returns on our investments or may bear substantial risk of capital loss. A significant part of our competitive advantage stems from the fact
that the market for investments in LMM companies is underserved by traditional commercial banks and other financing sources. A
significant increase in the number and/or the size of our competitors in this target market could force us to accept less attractive investment
terms. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC.

We are dependent upon our key investment personnel for our future success.

       We depend on the members of our investment team, particularly Dwayne L. Hyzak, David L. Magdol, Vincent D. Foster, Curtis L.
Hartman, K. Colton Braud, III, Nicholas T. Meserve, Samuel A. Cashiola and Watt R. Matthews, for the identification, review, final
selection, structuring, closing and monitoring of our investments. These employees have significant investment expertise and relationships
that we rely on to implement our business plan. Although we have entered into a non-compete agreement with Mr. Foster and non-compete
arrangements with all of our executive officers and other key employees in connection with their restricted stock grants, we have no
guarantee that he or any other employees will remain employed with us. If

24

Table of Contents

we lose the services of these individuals, we may not be able to operate our business as we expect, and our ability to compete could be
harmed, which could cause our operating results to suffer.

Our success depends on attracting and retaining qualified personnel in a competitive environment.

       Our growth will require that we retain new investment and administrative personnel in a competitive market. Our ability to attract and
retain personnel with the requisite credentials, experience and skills depends on several factors including, but not limited to, our ability to
offer competitive wages, benefits and professional growth opportunities. Many of the entities, including investment funds (such as private
equity funds, debt funds and mezzanine funds) and traditional financial services companies, with which we compete for experienced
personnel have greater resources than we have.

       The competitive environment for qualified personnel may require us to take certain measures to ensure that we are able to attract and
retain experienced personnel. Such measures may include increasing the attractiveness of our overall compensation packages, altering the
structure of our compensation packages through the use of additional forms of compensation, or other steps. The inability to attract and
retain experienced personnel would have a material adverse effect on our business.

Our business model depends to a significant extent upon strong referral relationships, and our inability to maintain or develop
these relationships, as well as the failure of these relationships to generate investment opportunities, could adversely affect our
business.

       We expect that members of our management team will maintain their relationships with intermediaries, financial institutions,
investment bankers, commercial bankers, financial advisors, attorneys, accountants, consultants and other individuals within our network,
and we will rely to a significant extent upon these relationships to provide us with potential investment opportunities. If our management
team fails to maintain its existing relationships or develop new relationships with sources of investment opportunities, we will not be able to
grow our Investment Portfolio. In addition, individuals with whom members of our management team have relationships are not obligated
to provide us with investment opportunities, and, therefore, there is no assurance that such relationships will generate investment
opportunities for us.

Our executive officers and employees, through the External Investment Manager, may manage other investment funds,
including HMS Income, that operate in the same or a related line of business as we do, which may result in significant conflicts
of interest.

       Our executive officers and employees, through the External Investment Manager, may manage other investment funds that operate in
the same or a related line of business as we do. Accordingly, they may have obligations to such other entities, the fulfillment of which
obligations may not be in the best interests of us or our stockholders. During May 2012, we entered into an investment sub-advisory
agreement with HMS Adviser, which is the investment advisor to HMS Income, a non-listed BDC, to provide certain investment advisory
services to HMS Adviser. In December 2013, after obtaining required no-action relief from the SEC to allow us to own a registered
investment adviser, we assigned the sub-advisory agreement to the External Investment Manager since the fees received from such
arrangement could otherwise have negative consequences on our ability to meet the source-of-income requirement necessary for us to
maintain our RIC tax treatment. Under the investment sub-advisory agreement, the External Investment Manager is entitled to 50% of the
base management fee and the incentive fees earned by HMS Adviser under its advisory agreement with HMS Income. The sub-advisory
relationship requires us to commit resources to achieving HMS Income's investment objective, while such resources were previously solely
devoted to achieving our investment objective. Our investment objective and investment strategies are very similar to those of HMS
Income and it is likely that an investment appropriate for us or HMS Income would be appropriate for the other entity. As a result, we and
HMS Income requested an exemptive order from the SEC permitting co-investments by us and HMS Income in certain negotiated
transactions where our co-investing would otherwise be prohibited under the 1940 Act. The SEC granted the exemptive order in April 2014,
and we have made, and in the future intend to continue to make, such co-investments with HMS Income in

25

Table of Contents

accordance with the conditions of the order. The order requires, among other things, that we and the External Investment Manager consider
whether each such investment opportunity is appropriate for HMS Income and, if it is appropriate, to propose an allocation of the
investment opportunity between us and HMS Income. As a consequence, it may be more difficult for us to maintain or increase the size of
our Investment Portfolio in the future. Although we will endeavor to allocate investment opportunities in a fair and equitable manner,
including in accordance with the conditions set forth in the exemptive order issued by the SEC when relying on such order, we may face
conflicts in allocating investment opportunities between us and HMS Income. Because the External Investment Manager may receive
performance-based fee compensation from HMS Income, this may provide an incentive to allocate opportunities to HMS Income instead of
us. We have implemented an allocation policy to ensure the equitable distribution of investment opportunities and, as a result, may be
unable to participate in certain investments based upon such allocation policy.

We, through the External Investment Manager, derive revenues from managing third party funds pursuant to management
agreements that may be terminated pursuant to the terms of such agreements or requirements under the 1940 Act.

       The External Investment Manager earns management fees based on the assets of the funds under management and may earn incentive
fees, or a carried interest, based on the performance of the funds managed, including HMS Income. The terms of fund investment
management agreements generally give the manager of the fund and the fund itself the right to terminate the management agreement in
certain circumstances. With respect to funds that are not exempt from regulation under the 1940 Act, the fund's investment management
agreement must be approved annually by (a) such fund's board of directors or by the vote of a majority of such fund's stockholders and
(b) the majority of the independent members of such fund's board of directors and, in certain cases, by its stockholders, as required by law.
The funds' investment management agreements can also be terminated by the majority of such fund's stockholders. Termination of any
such management agreements would reduce the fees we earn from the relevant funds through the External Investment Manager, which
could have a material adverse effect on our results of operations. Currently, HMS Income, an investment company that has elected to be
regulated as a business development company under the 1940 Act, is subject to these provisions of the 1940 Act.

Regulations governing our operation as a BDC will affect our ability to, and the way in which we, raise additional capital.

       Our business will require capital to operate and grow. We may acquire such additional capital from the following sources:

       Senior Securities.    We may issue debt securities or preferred stock and/or borrow money from banks or other financial
institutions, which we refer to collectively as senior securities. As a result of issuing senior securities, we will be exposed to
additional risks, including the following:

•

•

•

Under the provisions of the 1940 Act, we are permitted, as a BDC, to issue senior securities only in amounts
such that our asset coverage, as defined in the 1940 Act, equals at least 200% (or 150% if certain
requirements are met) immediately after each issuance of senior securities. We have received exemptive
relief from the SEC to permit us to exclude the SBA-guaranteed debentures of the Funds from our asset
coverage test under the 1940 Act. If the value of our assets declines, we may be unable to satisfy this test. If
that happens, we will be prohibited from issuing debt securities or preferred stock and/or borrowing money
from banks or other financial institutions and may not be permitted to declare a dividend or make any
distribution to stockholders or repurchase shares until such time as we satisfy this test. 

Any amounts that we use to service our debt or make payments on preferred stock will not be available for
dividends to our common stockholders. 

It is likely that any senior securities or other indebtedness we issue will be governed by an indenture or other
instrument containing covenants restricting our operating flexibility.

26

Table of Contents

Additionally, some of these securities or other indebtedness may be rated by rating agencies, and in obtaining
a rating for such securities and other indebtedness, we may be required to abide by operating and investment
guidelines that further restrict operating and financial flexibility.

•

•

•

We and, indirectly, our stockholders will bear the cost of issuing and servicing such securities and other
indebtedness. 

Preferred stock or any convertible or exchangeable securities that we issue in the future may have rights,
preferences and privileges more favorable than those of our common stock, including separate voting rights
and could delay or prevent a transaction or a change in control to the detriment of the holders of our common
stock. 

Any unsecured debt issued by us would rank (i) pari passu with our current and future unsecured
indebtedness and effectively subordinated to all of our existing and future secured indebtedness, to the extent
of the value of the assets securing such indebtedness, and (ii) structurally subordinated to all existing and
future indebtedness and other obligations of any of our subsidiaries, including the SBA-guaranteed
debentures issued by the Funds.

       Additional Common Stock.    The 1940 Act prohibits us from selling shares of our common stock at a price below the current
net asset value per share of such stock, with certain exceptions. One such exception is prior stockholder approval of issuances below
current net asset value per share provided that our Board of Directors makes certain determinations. We did not seek stockholder
authorization to sell shares of our common stock below the then current net asset value per share of our common stock at our 2018
annual meeting of stockholders because our common stock price had been trading significantly above the net asset value per share
of our common stock since 2011. We may, however, sell our common stock, warrants, options or rights to acquire our common
stock, at a price below the current net asset value of the common stock if our Board of Directors determines that such sale is in the
best interests of our stockholders, and our stockholders approve such sale. See "— Stockholders may incur dilution if we sell shares
of our common stock in one or more offerings at prices below the then current net asset value per share of our common stock or
issue securities to subscribe to, convert to or purchase shares of our common stock" for a discussion of the risks related to us issuing
shares of our common stock below net asset value. Our stockholders have authorized us to issue warrants, options or rights to
subscribe for, convert to, or purchase shares of our common stock at a price per share below the net asset value per share, subject to
the applicable requirements of the 1940 Act. There is no expiration date on our ability to issue such warrants, options, rights or
convertible securities based on this stockholder approval. If we raise additional funds by issuing more common stock or senior
securities convertible into, or exchangeable for, our common stock, the percentage ownership of our stockholders at that time would
decrease, and they may experience dilution. Moreover, we can offer no assurance that we will be able to issue and sell additional
equity securities in the future, on favorable terms or at all.

The Funds are licensed by the SBA, and therefore subject to SBA regulations.

       The Funds, our wholly owned subsidiaries, are licensed to act as SBICs and are regulated by the SBA. The SBA also places certain
limitations on the financing terms of investments by SBICs in portfolio companies and prohibits SBICs from providing funds for certain
purposes or to businesses in a few prohibited industries. Compliance with SBA requirements may cause the Funds to forego attractive
investment opportunities that are not permitted under SBA regulations.

       Further, the SBA regulations require, among other things, that a licensed SBIC be periodically examined by the SBA and audited by an
independent auditor, in each case to determine the SBIC's compliance with the relevant SBA regulations. The SBA prohibits, without prior
SBA approval, a "change of control" of an SBIC or transfers that would result in any person (or a group of persons acting in concert)
owning 10% or more of a class of capital stock of a licensed SBIC. If the Funds fail to comply with applicable SBIC regulations, the SBA
could, depending on the severity of the violation, limit or prohibit their use of SBIC debentures, declare outstanding SBIC debentures
immediately due and payable, and/or limit them from making new investments.

27

Table of Contents

In addition, the SBA can revoke or suspend a license for willful or repeated violation of, or willful or repeated failure to observe, any
provision of the Small Business Investment Act of 1958 or any rule or regulation promulgated thereunder. Such actions by the SBA would,
in turn, negatively affect us.

Because we borrow money, the potential for gain or loss on amounts invested in us is magnified and may increase the risk of
investing in us.

       Borrowings, also known as leverage, magnify the potential for loss on investments in our indebtedness and gain or loss on investments
in our equity capital. As we use leverage to partially finance our investments, you will experience increased risks of investing in our
securities. We, through the Funds, issue debt securities guaranteed by the SBA and sold in the capital markets. As a result of its guarantee
of the debt securities, the SBA has fixed dollar claims on the assets of the Funds that are superior to the claims of our securities holders. We
may also borrow from banks and other lenders, including under our Credit Facility, and may issue debt securities or enter into other types
of borrowing arrangements in the future. See "Management's Discussion and Analysis of Financial Condition and Results of Operations —
Liquidity and Capital Resources — Capital Resources" for a discussion regarding our outstanding indebtedness. If the value of our assets
decreases, leveraging would cause net asset value to decline more sharply than it otherwise would have had we not leveraged our business.
Similarly, any decrease in our income would cause net investment income to decline more sharply than it would have had we not leveraged
our business. Such a decline could negatively affect our ability to pay common stock dividends, scheduled debt payments or other
payments related to our securities. Use of leverage is generally considered a speculative investment technique.

       As of December 31, 2018, we, through the Funds, had $345.8 million of outstanding indebtedness guaranteed by the SBA, which had a
weighted-average annualized interest cost of approximately 3.7%. The debentures guaranteed by the SBA have a maturity of ten years, with
a current weighted-average remaining maturity of 5.6 years as of December 31, 2018, and require semiannual payments of interest. We will
need to generate sufficient cash flow to make required interest payments on the debentures. If we are unable to meet the financial
obligations under the debentures, the SBA, as a creditor, will have a superior claim to the assets of the Funds over our securities holders in
the event we liquidate or the SBA exercises its remedies under such debentures as the result of a default by us.

       In addition, as of December 31, 2018, we had $301.0 million outstanding under our Credit Facility. Borrowings under the Credit
Facility bear interest, subject to our election, on a per annum basis at a rate equal to the applicable LIBOR rate (2.5% as of December 31,
2018) plus (i) 1.875% (or the applicable base rate (Prime Rate of 5.5% as of December 31, 2018) plus 0.875%), as long as we meet certain
agreed upon excess collateral and maximum leverage requirements or (ii) 2.0% (or the applicable base rate plus 1.0%) otherwise. We pay
unused commitment fees of 0.25% per annum on the unused lender commitments under the Credit Facility. If we are unable to meet the
financial obligations under the Credit Facility, the Credit Facility lending group will have a superior claim to the assets of MSCC and its
subsidiaries (excluding the assets of the Funds) over our stockholders in the event we liquidate or the lending group exercises its remedies
under the Credit Facility as the result of a default by us.

       In April 2013, we issued $92.0 million, including the underwriters' full exercise of their over-allotment option, in aggregate principal
amount of the 6.125% Notes (the "6.125% Notes"). The 6.125% Notes bore interest at a rate of 6.125% per year payable quarterly on
January 1, April 1, July 1 and October 1 of each year. The total net proceeds to us from the 6.125% Notes, after underwriting discounts and
estimated offering expenses payable, were approximately $89.0 million. On April 2, 2018, we redeemed the entire principal amount of the
issued and outstanding 6.125% Notes effective April 1, 2018 (the "Redemption Date"). The 6.125% Notes were redeemed at par value, plus
the accrued and unpaid interest thereon from January 1, 2018, through, but excluding, the Redemption Date. As part of the redemption, we
recognized a realized loss on extinguishment of debt of $1.5 million in the second quarter of 2018 related to the write-off of the related
unamortized deferred financing costs.

28

Table of Contents

       In November 2014, we issued $175.0 million in aggregate principal amount of 4.50% unsecured notes due 2019 (the "4.50% Notes due
2019") at an issue price of 99.53%. As of December 31, 2018, the outstanding balance of the 4.50% Notes due 2019 was $175.0 million.
The 4.50% Notes due 2019 are unsecured obligations and rank pari passu with our current and future unsecured indebtedness; senior to any
of our future indebtedness that expressly provides it is subordinated to the 4.50% Notes due 2019; effectively subordinated to all of our
existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, including borrowings under
our Credit Facility; and structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries,
including without limitation, the indebtedness of the Funds. The 4.50% Notes due 2019 mature on December 1, 2019, and may be
redeemed in whole or in part at any time at our option subject to certain make-whole provisions.

       In November 2017, we issued $185.0 million in aggregate principal amount of 4.50% unsecured notes due 2022 (the "4.50% Notes due
2022," together with the 4.50% Notes due 2019, the "Notes") at an issue price of 99.16%. As of December 31, 2018, the outstanding
balance of the 4.50% Notes due 2022 was $185.0 million. The 4.50% Notes due 2022 are unsecured obligations and rank pari passu with
our current and future unsecured indebtedness; senior to any of our future indebtedness that expressly provides it is subordinated to the
4.50% Notes due 2022; effectively subordinated to all of our existing and future secured indebtedness, to the extent of the value of the
assets securing such indebtedness, including borrowings under our Credit Facility; and structurally subordinated to all existing and future
indebtedness and other obligations of any of our subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50% Notes
due 2022 mature on December 1, 2022, and may be redeemed in whole or in part at any time at our option subject to certain make-whole
provisions.

       Illustration.     The following table illustrates the effect of leverage on returns from an investment in our common stock
assuming various annual returns, net of expenses. The calculations in the table below are hypothetical and actual returns may be

Assumes $2,553.4 million in total assets, $1,006.8 million in debt outstanding, $1,476.0 million in net assets, and a
weighted-average interest rate of 4.2%. Actual interest payments may be different. 

In order for us to cover our annual interest payments on indebtedness, we must achieve annual returns on our
December 31, 2018 total assets of at least 1.7%.

       Our ability to achieve our investment objective may depend in part on our ability to access additional leverage on favorable terms by
issuing debentures guaranteed by the SBA through the Funds, by borrowing from banks or insurance companies or by issuing other debt
securities and there can be no assurance that such additional leverage can in fact be achieved.

All of our assets are subject to security interests under our secured Credit Facility or subject to a superior claim over our
stockholders by the SBA and if we default on our obligations under the Credit Facility or with respect to our SBA-guaranteed
debentures, we may suffer adverse consequences, including foreclosure on our assets.

       Substantially all of our assets are currently pledged as collateral under our Credit Facility or are subject to a superior claim over our
stockholders by the SBA. If we default on our obligations under the Credit Facility or our SBA-guaranteed debentures, the lenders and/or
the SBA may have the right to foreclose upon and sell, or otherwise transfer, the collateral subject to their security interests or their
superior claim. In such event, we may be forced to sell our investments to raise funds to repay our outstanding borrowings in order to

29

 
 
 
Table of Contents

avoid foreclosure and these forced sales may be at times and at prices we would not consider advantageous. Moreover, such deleveraging
of our company could significantly impair our ability to effectively operate our business in the manner in which we have historically
operated. As a result, we could be forced to curtail or cease new investment activities and lower or eliminate the dividends that we have
historically paid to our stockholders. In addition, if the lenders exercise their right to sell the assets pledged under our Credit Facility, such
sales may be completed at distressed sale prices, thereby diminishing or potentially eliminating the amount of cash available to us after
repayment of the amounts outstanding under the Credit Facility.

Recent legislation may allow us to incur additional leverage.

       The 1940 Act generally prohibits us from incurring indebtedness unless immediately after such borrowing we have an asset coverage
for total borrowings of at least 200% (i.e., the amount of debt may not exceed 50% of the value of our assets). However, legislation passed
in March 2018 has modified the 1940 Act by allowing a BDC to increase the maximum amount of leverage it may incur by lowering the
required asset coverage ratio of 200% to an asset coverage ratio of 150% (i.e., the amount of debt may not exceed 662/3% of the value of
our assets), if certain requirements are met. Under the legislation, we are allowed to increase our leverage capacity if stockholders
representing at least a majority of the votes cast, when a quorum is met, approve a proposal to do so. If we receive stockholder approval, we
would be allowed to increase our leverage capacity on the first day after such approval. Alternatively, the legislation allows a "required
majority" (as defined in Section 57(o) of the 1940 Act) of the members of our board of directors to approve an increase in our leverage
capacity, and such approval would become effective after one year from the date of approval. In either case, we would be required to make
certain disclosures on our website and in SEC filings regarding, among other things, the receipt of approval to increase our leverage, our
leverage capacity and usage, and risks related to leverage. As a result of this legislation, we may be able to increase our leverage up to an
amount that reduces our asset coverage ratio from 200% to 150% (i.e., the amount of debt may not exceed 662/3% of the value of our
assets). See "Risk Factors — Risks Relating to Our Business and Structure — Because we borrow money, the potential for gain or loss on
amounts invested in us is magnified and may increase the risk of investing in us" for a discussion of the risks associated with leverage.

Further downgrades of the U.S. credit rating, automatic spending cuts or another government shutdown could negatively impact
our liquidity, financial condition and earnings.

       Recent U.S. debt ceiling and budget deficit concerns have increased the possibility of additional credit-rating downgrades and
economic slowdowns, or a recession in the U.S. Although U.S. lawmakers passed legislation to raise the federal debt ceiling on multiple
occasions, ratings agencies have lowered or threatened to lower the long-term sovereign credit rating on the United States. The impact of
this or any further downgrades to the U.S. government's sovereign credit rating or its perceived creditworthiness could adversely affect the
U.S. and global financial markets and economic conditions. Absent further quantitative easing by the Federal Reserve, these developments
could cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the debt markets on favorable
terms. In addition, disagreement over the federal budget has caused the U.S. federal government to shut down for periods of time.
Continued adverse political and economic conditions could have a material adverse effect on our business, financial condition and results of
operations.

The interest rates of our floating-rate loans to our portfolio companies that extend beyond 2021 might be subject to change
based on recent regulatory changes

       LIBOR is the basic rate of interest used in lending transactions between banks on the London interbank market and is widely used as a
reference for setting the interest rate on loans globally. We typically use LIBOR as a reference rate in floating-rate loans we extend to
portfolio companies such that the interest due to us pursuant to a term loan extended to a portfolio company is calculated using LIBOR. The
terms of our debt investments generally include minimum interest rate floors which are calculated based on LIBOR.

30

Table of Contents

       On July 27, 2017, the United Kingdom's Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out
LIBOR by the end of 2021. It is unclear if at that time whether LIBOR will cease to exist or if new methods of calculating LIBOR will be
established such that it continues to exist after 2021. As such, the potential effect of any such event on our net investment income cannot
yet be determined. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee
comprised of large U.S. financial institutions, is considering replacing U.S. dollar LIBOR with a new index calculated by short term
repurchase agreements, backed by Treasury securities. If LIBOR ceases to exist, we may need to renegotiate the credit agreements
extending beyond 2021 with our portfolio companies that utilize LIBOR as a factor in determining the interest rate to replace LIBOR with
the new standard that is established. In addition, any further changes or reforms to the determination or supervision of LIBOR may result in
a sudden or prolonged increase or decrease in reported LIBOR, which could have an adverse impact on the market value for or value of any
LIBOR-linked securities, loans and other financial obligations or extensions of credit held by or due to us and could have a material adverse
effect on our business, financial condition and results of operations.

We may experience fluctuations in our operating results.

       We could experience fluctuations in our operating results due to a number of factors, including our ability or inability to make
investments in companies that meet our investment criteria, the interest rate payable on the debt securities we acquire, the level of portfolio
dividend and fee income, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses,
the degree to which we encounter competition in our markets and general economic conditions. As a result of these factors, operating
results for any period should not be relied upon as being indicative of performance in future periods.

Our Board of Directors may change our operating policies and strategies without prior notice or stockholder approval, the
effects of which may be adverse.

       Our Board of Directors has the authority to modify or waive our current operating policies, investment criteria and strategies without
prior notice and without stockholder approval. We cannot predict the effect any changes to our current operating policies, investment
criteria and strategies would have on our business, net asset value, operating results and value of our stock. However, the effects might be
adverse, which could negatively impact our ability to pay interest and principal payments to holders of our debt instruments and dividends
to our stockholders and cause our investors to lose all or part of their investment in us.

We will be subject to corporate-level U.S. federal income tax if we are unable to qualify as a RIC under Subchapter M of the
Code.

       To maintain RIC tax treatment under the Code, we must meet the following annual distribution, income source and asset diversification
requirements:

•

The Annual Distribution Requirement for a RIC will be satisfied if we distribute to our stockholders on an annual
basis at least 90% of our net ordinary taxable income and realized net short-term capital gains in excess of realized
net long-term capital losses, if any. Depending on the level of taxable income earned in a tax year, we may choose to
carry forward taxable income in excess of current year distributions into the next tax year and pay a 4% U.S. federal
excise tax on such income. Any such carryover taxable income must be distributed through a dividend declared prior
to filing the final tax return related to the year which generated such taxable income. For more information regarding
tax treatment, see "Business — Regulation — Taxation as a Regulated Investment Company." Because we use debt
financing, we are subject to certain asset coverage ratio requirements under the 1940 Act and are (and may in the
future become) subject to certain financial covenants under loan and credit agreements that could, under certain
circumstances, restrict us from making distributions necessary to satisfy the distribution requirement. In addition,
because we receive non-cash sources of income such as PIK interest which involves us recognizing taxable income
without receiving the cash representing

31

Table of Contents

such income, we may have difficulty meeting the distribution requirement. If we are unable to obtain cash from other
sources, we could fail to qualify for RIC tax treatment and thus become subject to corporate-level U.S. federal
income tax.

•

•

The source-of-income requirement will be satisfied if we obtain at least 90% of our gross income for each year from
distributions, interest, gains from the sale of stock or securities or similar sources. 

The asset diversification requirement will be satisfied if we meet certain asset diversification requirements at the end
of each quarter of our taxable year. To satisfy this requirement, at least 50% of the value of our assets must consist of
cash, cash equivalents, U.S. government securities, securities of other RICs, and other acceptable securities; and no
more than 25% of the value of our assets can be invested in the securities, other than U.S. government securities or
securities of other RICs, (i) of one issuer, (ii) of two or more issuers that are controlled, as determined under
applicable Code rules, by us and that are engaged in the same or similar or related trades or businesses or (iii) of
certain "qualified publicly traded partnerships."

       Failure to meet these requirements may result in our having to dispose of certain investments quickly in order to prevent the loss of
RIC status. Because most of our investments are in privately held companies, and therefore illiquid, any such dispositions could be made at
disadvantageous prices and could result in substantial losses. Moreover, if we fail to maintain RIC tax treatment for any reason and are
subject to corporate income tax, the resulting corporate taxes could substantially reduce our net assets, the amount of income available for
distribution and the amount of our distributions.

We may not be able to pay distributions to our stockholders, our distributions may not grow over time, and a portion of
distributions paid to our stockholders may be a return of capital, which is a distribution of the stockholders' invested capital.

       We intend to pay distributions to our stockholders out of assets legally available for distribution. We cannot assure you that we will
achieve investment results that will allow us to pay a specified level of cash distributions, previously projected distributions for future
periods, or year-to-year increases in cash distributions. Our ability to pay distributions might be adversely affected by, among other things,
the impact of one or more of the risk factors described herein. In addition, the inability to satisfy the asset coverage test applicable to us as a
BDC could limit our ability to pay distributions. All distributions will be paid at the discretion of our Board of Directors and will depend
on our earnings, our financial condition, maintenance of our RIC status, compliance with applicable BDC regulations, compliance with our
debt covenants, each of the Funds' compliance with applicable SBIC regulations and such other factors as our Board of Directors may deem
relevant from time to time. We cannot assure you that we will pay distributions to our stockholders in the future.

       When we make distributions, we will be required to determine the extent to which such distributions are paid out of current or
accumulated taxable earnings, recognized capital gains or capital. To the extent there is a return of capital, investors will be required to
reduce their basis in our stock for U.S. federal income tax purposes, which may result in higher tax liability when the shares are sold, even
if they have not increased in value or have lost value. In addition, any return of capital will be net of any sales load and offering expenses
associated with sales of shares of our common stock. In the future, our distributions may include a return of capital.

We may have difficulty paying the distributions required to maintain RIC tax treatment under the Code if we recognize income
before or without receiving cash representing such income.

       We will include in income certain amounts that we have not yet received in cash, such as: (i) amortization of original issue discount,
which may arise if we receive warrants in connection with the origination of a loan such that ascribing a value to the warrants creates
original issue discount in the debt instrument, if we invest in a debt investment at a discount to the par value of the debt security or possibly
in other circumstances; (ii) contractual payment-in-kind, or PIK, interest, which represents contractual interest

32

Table of Contents

added to the loan balance and due at the end of the loan term; (iii) contractual preferred dividends, which represents contractual dividends
added to the preferred stock and due at the end of the preferred stock term, subject to adequate profitability at the portfolio company; or
(iv) amortization of market discount, which is associated with loans purchased in the secondary market at a discount to par value. Such
amortization of original issue discounts, increases in loan balances as a result of contractual PIK arrangements, cumulative preferred
dividends, or amortization of market discount will be included in income before we receive the corresponding cash payments. We also may
be required to include in income certain other amounts before we receive such amounts in cash. Investments structured with these features
may represent a higher level of credit risk compared to investments generating income which must be paid in cash on a current basis. For
the year ended December 31, 2018, (i) approximately 1.0% of our total investment income was attributable to PIK income not paid
currently in cash, (ii) approximately 0.5% of our total investment income was attributable to amortization of original issue discount,
(iii) approximately 1.0% of our total investment income was attributable to cumulative dividend income not paid currently in cash, and
(iv) approximately 2.5% of our total investment income was attributable to amortization of market discount on loans purchased in the
secondary market at a discount.

       Since, in certain cases, we may recognize taxable income before or without receiving cash representing such income, we may have
difficulty meeting the Annual Distribution Requirement necessary to maintain RIC tax treatment under the Code. Accordingly, we may
have to sell some of our investments at times and/or at prices we would not consider advantageous, raise additional debt or equity capital or
forgo new investment opportunities for this purpose. If we are not able to obtain cash from other sources, we may fail to qualify for RIC tax
treatment and thus become subject to corporate-level U.S. federal income tax. For additional discussion regarding the tax implications of a
RIC, please see "Business — Regulation — Taxation as a Regulated Investment Company."

We may in the future choose to pay dividends in our own stock, in which case you may be required to pay tax in excess of the
cash you receive.

       We may distribute taxable dividends that are payable in part in our stock. Under certain applicable provisions of the Code and the
Treasury regulations, distributions payable by us in cash or in shares of stock (at the stockholders election) would satisfy the Annual
Distribution Requirement. The Internal Revenue Service has issued guidance providing that a dividend payable in stock or in cash at the
election of the stockholders will be treated as a taxable dividend eligible for the dividends paid deduction provided that at least 20% of the
total dividend is payable in cash and certain other requirements are satisfied. Taxable stockholders receiving such dividends will be
required to include the full amount of the dividend as ordinary income (or as long-term capital gain to the extent such dividend is properly
reported as a capital gain dividend) to the extent of our current and accumulated earnings and profits for U.S. federal income tax purposes.
As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash received. If a U.S.
stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in
income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-
U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such
dividend that is payable in stock. In addition, if a significant number of our stockholders determine to sell shares of our stock in order to pay
taxes owed on dividends, it may put downward pressure on the trading price of our stock.

Each of the Funds, as an SBIC, may be unable to make distributions to us that will enable us to meet or maintain RIC status,
which could result in the imposition of an entity-level tax.

       In order for us to continue to qualify for RIC tax treatment and to minimize corporate-level U.S. federal taxes, we will be required to
distribute substantially all of our net ordinary taxable income and net capital gain income, including taxable income from certain of our
subsidiaries, which includes the income from the Funds. We will be partially dependent on the Funds for cash distributions to enable us to
meet the RIC

33

Table of Contents

distribution requirements. The Funds may be limited by SBIC regulations from making certain distributions to us that may be necessary to
enable us to maintain our status as a RIC. We may have to request a waiver of the SBA's restrictions for the Funds to make certain
distributions to maintain our eligibility for RIC status. We cannot assure you that the SBA will grant such waiver and if the Funds are
unable to obtain a waiver, compliance with the SBIC regulations may result in loss of RIC tax treatment and a consequent imposition of an
entity-level tax on us.

Because we intend to distribute substantially all of our taxable income to our stockholders to maintain our status as a RIC, we
will continue to need additional capital to finance our growth, and regulations governing our operation as a BDC will affect our
ability to, and the way in which we, raise additional capital and make distributions.

       In order to satisfy the requirements applicable to a RIC and to minimize corporate-level U.S. federal taxes, we intend to distribute to our
stockholders substantially all of our net ordinary taxable income and net capital gain income. We may carry forward excess undistributed
taxable income into the next year, net of the 4% U.S. federal excise tax. Any such carryover taxable income must be distributed through a
dividend declared prior to filing the final tax return related to the year which generated such taxable income. As a BDC, we generally are
required to meet an asset coverage ratio, as defined in the 1940 Act, of at least 200% (or 150% if certain requirements are met) immediately
after each issuance of senior securities. This requirement limits the amount that we may borrow and may prohibit us from making
distributions. Because we will continue to need capital to grow our Investment Portfolio, this limitation may prevent us from incurring debt
and require us to raise additional equity at a time when it may be disadvantageous to do so.

       While we expect to be able to borrow and to issue additional debt and equity securities, we cannot assure you that debt and equity
financing will be available to us on favorable terms, or at all. In addition, as a BDC, we generally are not permitted to issue equity securities
priced below net asset value without stockholder approval. If additional funds are not available to us, we could be forced to curtail or cease
new investment activities, and our net asset value could decline.

Stockholders may incur dilution if we sell shares of our common stock in one or more offerings at prices below the then current
net asset value per share of our common stock or issue securities to subscribe to, convert to or purchase shares of our common
stock.

       The 1940 Act prohibits us from selling shares of our common stock at a price below the current net asset value per share of such stock,
with certain exceptions. One such exception is prior stockholder approval of issuances below net asset value provided that our Board of
Directors makes certain determinations. We did not seek stockholder authorization to sell shares of our common stock below the then
current net asset value per share of our common stock at our 2018 annual meeting of stockholders because our common stock price per
share had been trading significantly above the net asset value per share of our common stock. We may, however, seek such authorization at
future annual or special meetings of stockholders. Our stockholders have previously approved a proposal to authorize us to issue securities
to subscribe to, convert to, or purchase shares of our common stock in one or more offerings. Any decision to sell shares of our common
stock below the then current net asset value per share of our common stock or securities to subscribe to, convert to, or purchase shares of
our common stock would be subject to the determination by our Board of Directors that such issuance is in our and our stockholders' best
interests.

       If we were to sell shares of our common stock below net asset value per share, such sales would result in an immediate dilution to the
net asset value per share. This dilution would occur as a result of the sale of shares at a price below the then current net asset value per
share of our common stock and a proportionately greater decrease in a stockholder's interest in our earnings and assets and voting interest in
us than the increase in our assets resulting from such issuance. In addition, if we issue securities to subscribe to, convert to or purchase
shares of common stock, the exercise or conversion of such securities would increase the number of outstanding shares of our common
stock. Any such exercise would be dilutive on the voting power

34

Table of Contents

of existing stockholders, and could be dilutive with regard to dividends and our net asset value, and other economic aspects of the common
stock.

       Because the number of shares of common stock that could be so issued and the timing of any issuance is not currently known, the
actual dilutive effect cannot be predicted; however, the example below illustrates the effect of dilution to existing stockholders resulting
from the sale of common stock at prices below the net asset value of such shares.

       Illustration: Example of Dilutive Effect of the Issuance of Shares Below Net Asset Value.     Assume that Company XYZ has
1,000,000 total shares outstanding, $15,000,000 in total assets and $5,000,000 in total liabilities. The net asset value per share of the
common stock of Company XYZ is $10.00. The following table illustrates the reduction to net asset value, or NAV, and the dilution
experienced by Stockholder A following the sale of 40,000 shares of the common stock of Company XYZ at $9.50 per share, a
price below its NAV per share.

Changes in laws or regulations governing our operations may adversely affect our business or cause us to alter our business
strategy.

       We, the Funds, and our portfolio companies are subject to applicable local, state and federal laws and regulations. New legislation may
be enacted or new interpretations, rulings or regulations could be adopted, including those governing the types of investments we are
permitted to make, any of which could harm us and our stockholders, potentially with retroactive effect. In addition, any change to the
SBA's current debenture SBIC program could have a significant impact on our ability to obtain lower-cost leverage through the Funds, and
therefore, our ability to compete with other finance companies.

       Additionally, any changes to the laws and regulations governing our operations relating to permitted investments may cause us to alter
our investment strategy in order to avail ourselves of new or different opportunities. Such changes could result in material differences to the
strategies and plans set forth herein and may result in our investment focus shifting from the areas of expertise of our investment team to
other types of investments in which our investment team may have less expertise or little or no experience. Thus, any such changes, if they
occur, could have a material adverse effect on our results of operations and the value of your investment.

The Tax Cuts and Jobs Act could have a negative effect on us, our subsidiaries, our portfolio companies and the holders of our
securities.

       On December 20, 2017, the U.S. House of Representatives and the U.S. Senate each voted to approve H.R. 1 (the "Tax Cuts and Jobs
Act") and, on December 22, 2017, President Trump signed the Tax Cuts and Jobs Act into law. The Tax Cuts and Jobs Act made significant
changes to the U.S. federal income tax rules applicable to both individuals and entities, including corporations. The Tax Cuts and Jobs Act
includes provisions that, among other things, reduce the U.S. corporate tax rate, introduce a capital investment deduction, limit the interest
deduction, limit the use of net operating losses to offset future taxable income

and make extensive changes to the U.S. international tax system. Treasury and the Internal Revenue Service continue to release guidance in
the form of regulations providing rules for implementation and interpretation of the Tax Cuts and Jobs Act provisions. Uncertainty remains
regarding significant provisions of the Tax Cuts and Jobs Act while some of the Treasury regulations and guidance remain in proposed
form. Accordingly, we cannot predict any additional future impact the enactment of such legislation will have on us, our subsidiaries, our
portfolio companies and the holders of our securities.

Terrorist attacks, acts of war or natural disasters may affect any market for our securities, impact the businesses in which we
invest and harm our business, operating results and financial condition.

       Terrorist acts, acts of war or natural disasters may disrupt our operations, as well as the operations of the businesses in which we
invest. Such acts have created, and continue to create, economic and political uncertainties and have contributed to global economic
instability. Future terrorist activities, military or security operations, or natural disasters could further weaken the domestic/global
economies and create additional uncertainties, which may negatively impact the businesses in which we invest directly or indirectly and, in
turn, could have a material adverse impact on our business, operating results and financial condition. Losses from terrorist attacks and
natural disasters are generally uninsurable.

We are highly dependent on information systems and systems failures could significantly disrupt our business, which may, in
turn, negatively affect the market price of our common stock and our ability to pay dividends.

       Our business is highly dependent on our and third parties' communications and information systems. Any failure or interruption of
those systems, including as a result of the termination of an agreement with any third-party service providers, could cause delays or other
problems in our activities. Our financial, accounting, data processing, backup or other operating systems and facilities may fail to operate
properly or become disabled or damaged as a result of a number of factors including events that are wholly or partially beyond our control
and adversely affect our business. There could be:

•

•

•

•

sudden electrical or telecommunications outages; 

natural disasters such as earthquakes, tornadoes and hurricanes; 

events arising from local or larger scale political or social matters, including terrorist acts; and 

cyber attacks.

The failure in cyber security systems, as well as the occurrence of events unanticipated in our disaster recovery systems and
management continuity planning could impair our ability to conduct business effectively.

       The occurrence of a disaster such as a cyber-attack, a natural catastrophe, an industrial accident, a terrorist attack or war, events
unanticipated in our disaster recovery systems, or a support failure from external providers, could have an adverse effect on our ability to
conduct business and on our results of operations and financial condition, particularly if those events affect our computer-based data
processing, transmission, storage, and retrieval systems or destroy data. If a significant number of our managers were unavailable in the
event of a disaster, our ability to effectively conduct our business could be severely compromised.

       We depend heavily upon computer systems to perform necessary business functions. Despite our implementation of a variety of
security measures, our computer systems could be subject to cyber-attacks and unauthorized access, such as physical and electronic break-
ins or unauthorized tampering. Like other companies, we may experience threats to our data and systems, including malware and computer
virus attacks, unauthorized access, system failures and disruptions. If one or more of these events occurs, it could potentially jeopardize the
confidential, proprietary and other information processed and stored in, and transmitted through, our computer systems and networks, or
otherwise cause interruptions or malfunctions in

36

Table of Contents

our operations, which could result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties and/or
customer dissatisfaction or loss.

RISKS RELATED TO OUR INVESTMENTS

Our investments in portfolio companies involve higher levels of risk, and we could lose all or part of our investment.

       Investing in our portfolio companies exposes us indirectly to a number of significant risks. Among other things, these companies:

•

•

•

•

•

may have limited financial resources and may be unable to meet their obligations under their debt instruments that
we hold, which may be accompanied by a deterioration in the value of any collateral and a reduction in the likelihood
of us realizing any guarantees from subsidiaries or affiliates of our portfolio companies that we may have obtained in
connection with our investment, as well as a corresponding decrease in the value of the equity components of our
investments; 

may have shorter operating histories, narrower product lines, smaller market shares and/or significant customer
concentrations than larger businesses, which tend to render them more vulnerable to competitors' actions and market
conditions, as well as general economic downturns; 

are more likely to depend on the management talents and efforts of a small group of persons; therefore, the death,
disability, resignation, termination or significant under-performance of one or more of these persons could have a
material adverse impact on our portfolio company and, in turn, on us; 

generally have less predictable operating results, may from time to time be parties to litigation, may be engaged in
rapidly changing businesses with products subject to a substantial risk of obsolescence, and may require substantial
additional capital to support their operations, finance expansion or maintain their competitive position; and 

generally have less publicly available information about their businesses, operations and financial condition. We are
required to rely on the ability of our management team and investment professionals to obtain adequate information
to evaluate the potential returns from investing in these companies. If we are unable to uncover all material
information about these companies, we may not make a fully informed investment decision, and may lose all or part
of our investment.

       In addition, in the course of providing significant managerial assistance to certain of our portfolio companies, certain of our officers
and directors may serve as directors on the boards of such companies. To the extent that litigation arises out of our investments in these
companies, our officers and directors may be named as defendants in such litigation, which could result in an expenditure of funds (through
our indemnification of such officers and directors) and the diversion of management time and resources.

A decline in oil and natural gas prices could have a material adverse effect on us.

       A decline in oil and natural gas prices could adversely affect (i) the credit quality of our debt investments and (ii) the underlying
operating performance of our equity investments in energy-related businesses and in portfolio companies located in geographic areas which
are more sensitive to the health of the oil and gas industries. A decrease in credit quality and the operating performance would, in turn,
negatively affect the fair value of these investments, which would consequently negatively affect our net asset value. Should a decline in oil
and natural gas prices persist for an extended period of time, it is likely that the ability of these investments to satisfy financial or operating
covenants imposed by us or other lenders will be adversely affected, thereby negatively impacting their financial condition and their ability
to satisfy their debt service and other obligations to us. Likewise, should a decline in oil and natural gas prices persist, it is likely that our
energy-related portfolio companies' and other affected companies' cash flow and profit generating

37

Table of Contents

capacities would also be adversely affected thereby negatively impacting their ability to pay us dividends or distributions on our equity
investments.

We may be exposed to higher risks with respect to our investments that include original issue discount or PIK interest.

       Our investments may include original issue discount and contractual PIK interest, which represents contractual interest added to a loan
balance and due at the end of such loan's term. To the extent original issue discount or PIK interest constitute a portion of our income, we
are exposed to typical risks associated with such income being required to be included in taxable and accounting income prior to receipt of
cash, including the following:

•

•

•

•

original issue discount and PIK instruments may have higher yields, which reflect the payment deferral and credit
risk associated with these instruments; 

for accounting purposes, cash distributions to investors representing original issue discount income are not derived
from paid in capital, although they may be effectively paid from any offering proceeds during any given period; thus,
although the source for the cash used to pay a distribution of original issue discount income may come from the cash
invested by investors, the 1940 Act does not require that investors be given notice of this fact; 

original issue discount and PIK instruments may have unreliable valuations because their continuing accruals require
continuing judgments about the collectability of the deferred payments and the value of the collateral; and 

original issue discount and PIK instruments may represent a higher credit risk than coupon loans; even if the
conditions for income accrual under generally accepted accounting principles in the United States of America are
satisfied, a borrower could still default when actual payment is due upon the maturity of such loan.

The lack of liquidity in our investments may adversely affect our business.

       We invest in companies whose securities are not publicly traded, and whose securities will be subject to legal and other restrictions on
resale or will otherwise be less liquid than publicly traded securities. The illiquidity of these investments may make it difficult for us to sell
these investments when desired. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize
significantly less than the value at which we had previously recorded these investments. As a result, we do not expect to achieve liquidity in
our investments in the near-term. Our investments are usually subject to contractual or legal restrictions on resale or are otherwise illiquid
because there is usually no established trading market for such investments. The illiquidity of most of our investments may make it difficult
for us to dispose of them at a favorable price, and, as a result, we may suffer losses.

We may not have the funds or ability to make additional investments in our portfolio companies.

       We may not have the funds or ability to make additional investments in our portfolio companies. After our initial investment in a
portfolio company, we may be called upon from time to time to provide additional funds to such company or have the opportunity to
increase our investment through the extension of additional loans, the exercise of a warrant to purchase equity securities, or the funding of
additional equity investments. There is no assurance that we will make, or will have sufficient funds to make, follow-on investments. Any
decisions not to make a follow-on investment or any inability on our part to make such an investment may have a negative impact on a
portfolio company in need of such an investment, may result in a missed opportunity for us to increase our participation in a successful
operation, may reduce our ability to protect an existing investment or may reduce the expected yield on the investment.

38

Table of Contents

Our portfolio companies may incur debt that ranks equally with, or senior to, our investments in such companies.

       We invest primarily in the secured term debt of LMM, Private Loan and Middle Market companies and equity issued by LMM
companies. Our portfolio companies may have, or may be permitted to incur, other debt that ranks equally with, or senior to, the debt in
which we invest. By their terms, such debt instruments may entitle the holders to receive payment of interest or principal on or before the
dates on which we are entitled to receive payments with respect to the debt instruments in which we invest. Also, in the event of
insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of debt instruments ranking senior to our
investment in that portfolio company would typically be entitled to receive payment in full before we receive any distribution. After
repaying such senior creditors, such portfolio company may not have any remaining assets to use for repaying its obligation to us. In the
case of debt ranking equally with debt instruments in which we invest, we would have to share on an equal basis any distributions with
other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant
portfolio company.

There may be circumstances where our debt investments could be subordinated to claims of other creditors or we could be
subject to lender liability claims.

       Even though we may have structured certain of our investments as secured loans, if one of our portfolio companies were to go
bankrupt, depending on the facts and circumstances, and based upon principles of equitable subordination as defined by existing case law, a
bankruptcy court could subordinate all or a portion of our claim to that of other creditors and transfer any lien securing such subordinated
claim to the bankruptcy estate. The principles of equitable subordination defined by case law have generally indicated that a claim may be
subordinated only if its holder is guilty of misconduct or where the senior loan is re-characterized as an equity investment and the senior
lender has actually provided significant managerial assistance to the bankrupt debtor. We may also be subject to lender liability claims for
actions taken by us with respect to a borrower's business or instances where we exercise control over the borrower. It is possible that we
could become subject to a lender liability claim, including as a result of actions taken in rendering significant managerial assistance or
actions to compel and collect payments from the borrower outside the ordinary course of business.

Second priority liens on collateral securing loans that we make to our portfolio companies may be subject to control by senior
creditors with first priority liens. If there is a default, the value of the collateral may not be sufficient to repay in full both the
first priority creditors and us.

       Certain loans that we make are secured by a second priority security interest in the same collateral pledged by a portfolio company to
secure senior debt owed by the portfolio company to commercial banks or other traditional lenders. Often the senior lender has procured
covenants from the portfolio company prohibiting the incurrence of additional secured debt without the senior lender's consent. Prior to and
as a condition of permitting the portfolio company to borrow money from us secured by the same collateral pledged to the senior lender,
the senior lender will require assurances that it will control the disposition of any collateral in the event of bankruptcy or other default. In
many such cases, the senior lender will require us to enter into an "intercreditor agreement" prior to permitting the portfolio company to
borrow from us. Typically the intercreditor agreements we are requested to execute expressly subordinate our debt instruments to those
held by the senior lender and further provide that the senior lender shall control: (1) the commencement of foreclosure or other proceedings
to liquidate and collect on the collateral; (2) the nature, timing and conduct of foreclosure or other collection proceedings; (3) the
amendment of any collateral document; (4) the release of the security interests in respect of any collateral; and (5) the waiver of defaults
under any security agreement. Because of the control we may cede to senior lenders under intercreditor agreements we may enter, we may
be unable to realize the proceeds of any collateral securing some of our loans.

39

Table of Contents

       Finally, the value of the collateral securing our debt investment will ultimately depend on market and economic conditions, the
availability of buyers and other factors. Therefore, there can be no assurance that the proceeds, if any, from the sale or sales of all of the
collateral would be sufficient to satisfy the loan obligations secured by our first or second priority liens. There is also a risk that such
collateral securing our investments will decrease in value over time, will be difficult to sell in a timely manner, will be difficult to appraise
and will fluctuate in value based upon the success of the portfolio company and market conditions. If such proceeds are not sufficient to
repay amounts outstanding under the loan obligations secured by our second priority liens, then we, to the extent not repaid from the
proceeds of the sale of the collateral, will only have an unsecured claim against the company's remaining assets, if any.

We are a non-diversified investment company within the meaning of the 1940 Act, and therefore we are not limited with respect
to the proportion of our assets that may be invested in securities of a single issuer.

       We are classified as a non-diversified investment company within the meaning of the 1940 Act, which means that we are not limited
by the 1940 Act with respect to the proportion of our assets that we may invest in securities of a single issuer. To the extent that we assume
large positions in the securities of a small number of issuers, our net asset value may fluctuate to a greater extent than that of a diversified
investment company as a result of changes in the financial condition or the market's assessment of the issuer. We may also be more
susceptible to any single economic or regulatory occurrence than a diversified investment company. Beyond our RIC asset diversification
requirements, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio
companies. See "Risk Factors — Risks Relating to Our Business and Structure — We will be subject to corporate-level U.S. federal income
tax if we are unable to qualify as a RIC under Subchapter M of the Code."

We generally will not control our portfolio companies.

       We do not, and do not expect to, control the decision making in many of our portfolio companies, even though we may have board
representation or board observation rights, and our debt agreements may contain certain restrictive covenants. As a result, we are subject to
the risk that a portfolio company in which we invest will make business decisions with which we disagree and the management of such
company will take risks or otherwise act in ways that do not serve our interests as debt investors or minority equity holders. Due to the lack
of liquidity for our investments in non-traded companies, we may not be able to dispose of our interests in our portfolio companies as
readily as we would like or at an appropriate valuation. As a result, a portfolio company may make decisions that would decrease the value
of our portfolio holdings.

Defaults by our portfolio companies will harm our operating results.

       A portfolio company's failure to satisfy financial or operating covenants imposed by us or other lenders could lead to non-payment of
interest and other defaults and, potentially, termination of its loans and foreclosure on its secured assets, which could trigger cross-defaults
under other agreements and jeopardize a portfolio company's ability to meet its obligations under the debt or equity securities that we hold.
We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms, which may include the waiver of
certain financial covenants, with a defaulting portfolio company.

Any unrealized depreciation we experience in our portfolio may be an indication of future realized losses, which could reduce
our income and gains available for distribution.

       As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at the fair value as
determined in good faith by our Board of Directors. Decreases in the market values or fair values of our investments will be recorded as
unrealized depreciation. Any unrealized depreciation in our portfolio could be an indication of a portfolio company's inability to meet its
repayment obligations to us with respect to affected loans or a potential impairment of the value of affected equity investments. This could
result in realized losses in the future and ultimately in reductions of our income and gains available for distribution in future periods.

40

Table of Contents

Prepayments of our debt investments by our portfolio companies could adversely impact our results of operations and reduce our
return on equity.

       We are subject to the risk that the investments we make in our portfolio companies may be repaid prior to maturity. When this occurs,
we will generally reinvest these proceeds in temporary investments, pending their future investment in new portfolio companies. These
temporary investments will typically have substantially lower yields than the debt being prepaid and we could experience significant
delays in reinvesting these amounts. Any future investment in a new portfolio company may also be at lower yields than the debt that was
repaid. As a result, our results of operations could be materially adversely affected if one or more of our portfolio companies elect to prepay
amounts owed to us. Additionally, prepayments could negatively impact our return on equity, which could result in a decline in the market
price of our securities.

Changes in interest rates may affect our cost of capital, net investment income and value of our investments.

       Some of our debt investments will bear interest at variable rates and may be negatively affected by changes in market interest rates. An
increase in market interest rates would increase the interest costs and reduce the cash flows of our portfolio companies that have variable
rate debt instruments, a situation which could reduce the value of the investment. The value of our investments could also be reduced from
an increase in market interest rates as rates available to investors could make an investment in our securities less attractive than alternative
investments. In addition, an increase in interest rates would make it more expensive for us to use debt to finance our investments. As a
result, a significant increase in market interest rates could increase our cost of capital, which would reduce our net investment income.
Conversely, decreases in market interest rates could negatively impact the interest income from our variable rate debt investments. A
decrease in market interest rates may also have an adverse impact on our returns by requiring us to accept lower yields on our debt
investments and by increasing the risk that our portfolio companies will prepay our debt investments, resulting in the need to redeploy
capital at potentially lower rates. See further discussion and analysis at "Item 7A. Quantitative and Qualitative Disclosures about Market
Risk".

We may not realize gains from our equity investments.

       Certain investments that we have made in the past and may make in the future include warrants or other equity securities. Investments
in equity securities involve a number of significant risks, including the risk of further dilution as a result of additional issuances, inability to
access additional capital and failure to pay current distributions. Investments in preferred securities involve special risks, such as the risk of
deferred distributions, credit risk, illiquidity and limited voting rights. In addition, we may from time to time make non-control, equity
investments in portfolio companies. Our goal is ultimately to realize gains upon our disposition of such equity interests. However, the
equity interests we receive may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains
from our equity interests, and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other
losses we experience. We also may be unable to realize any value if a portfolio company does not have a liquidity event, such as a sale of
the business, recapitalization or public offering, which would allow us to sell the underlying equity interests. We often seek puts or similar
rights to give us the right to sell our equity securities back to the portfolio company issuer; however, we may be unable to exercise these put
rights for the consideration provided in our investment documents if the issuer is in financial distress.

Our investments in foreign securities may involve significant risks in addition to the risks inherent in U.S. investments.

       Our investment strategy contemplates potential investments in debt securities of foreign companies. Investing in foreign companies
may expose us to additional risks not typically associated with investing in securities of U.S. companies. These risks include changes in
exchange control regulations, political and social instability, expropriation, imposition of foreign taxes, less liquid markets and less
available information than is generally the case in the U.S., higher transaction costs, less government supervision of exchanges, brokers and

41

Table of Contents

issuers, less developed bankruptcy laws, difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards
and greater price volatility.

       Although most of our investments will be U.S. dollar denominated, any investments denominated in a foreign currency will be subject
to the risk that the value of a particular currency will change in relation to one or more other currencies. Among the factors that may affect
currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different
currencies, long-term opportunities for investment and capital appreciation, and political developments.

RISKS RELATING TO OUR SECURITIES

Shares of closed-end investment companies, including BDCs, may trade at a discount to their net asset value.

       Shares of closed-end investment companies, including BDCs, may trade at a discount to net asset value. This characteristic of closed-
end investment companies and BDCs is separate and distinct from the risk that our net asset value per share may decline. We cannot predict
whether our common stock will trade at, above or below net asset value. In addition, if our common stock trades below our net asset value
per share, we will generally not be able to issue additional common stock at the market price unless our stockholders approve such a sale
and our Board of Directors makes certain determinations. See "Risk Factors — Risks Relating to Our Business and Structure —
Stockholders may incur dilution if we sell shares of our common stock in one or more offerings at prices below the then current net asset
value per share of our common stock or issue securities to subscribe to, convert to or purchase shares of our common stock" for a discussion
related to us issuing shares of our common stock below net asset value.

We may be unable to invest a significant portion of the net proceeds from an offering or from exiting an investment or other
capital on acceptable terms, which could harm our financial condition and operating results.

       Delays in investing the net proceeds raised in an offering or other capital raised or proceeds resulting from exiting an investment may
cause our performance to be worse than that of other fully invested BDCs or other lenders or investors pursuing comparable investment
strategies. We cannot assure you that we will be able to identify any investments that meet our investment objective or that any investment
that we make will produce a positive return. We may be unable to invest the net proceeds of any offering or other capital raised or
proceeds resulting from exiting an investment on acceptable terms within the time period that we anticipate or at all, which could harm our
financial condition and operating results.

       We anticipate that, depending on market conditions and the amount of the capital, it may take us a substantial period of time to invest
substantially all the capital in securities meeting our investment objective. During this period, we may invest the capital primarily in
marketable securities and idle funds investments, which generally consist of debt investments, independently rated debt investments,
certificates of deposit with financial institutions, diversified bond funds and publicly traded debt and equity investments and may produce
returns that are significantly lower than the returns which we expect to achieve when our portfolio is fully invested in securities meeting our
investment objective. Most of the debt investments that meet our investment criteria are, or would be if rated, below investment grade
quality. Indebtedness of below investment grade quality, which is often referred to as "junk," is regarded as having predominantly
speculative characteristics with respect to the issuer's capacity to pay interest and repay principal. As a result, any distributions that we pay
during such period may be substantially lower than the distributions that we may be able to pay when our portfolio is fully invested in
securities meeting our investment objective. In addition, until such time as the net proceeds of any offering or from exiting an investment or
other capital are invested in new securities meeting our investment objective, the market price for our securities may decline. Thus, the
initial return on your investment may be lower than when, if ever, our portfolio is fully invested in securities meeting our investment
objective.

Investing in our securities may involve a high degree of risk.

       The investments we make in accordance with our investment objective may result in a higher amount of risk than alternative
investment options and a higher risk of volatility or loss of principal. Our investments in portfolio companies involve higher levels of risk,
and therefore, an investment in our securities may not be suitable for someone with lower risk tolerance.

The market price of our securities may be volatile and fluctuate significantly.

       Fluctuations in the trading prices of our securities may adversely affect the liquidity of the trading market for our securities and, if we
seek to raise capital through future securities offerings, our ability to raise such capital. The market price and liquidity of the market for our
securities may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our
operating performance. These factors include:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

significant volatility in the market price and trading volume of securities of BDCs or other companies in our sector,
which are not necessarily related to the operating performance of these companies; 

changes in regulatory policies, accounting pronouncements or tax guidelines, particularly with respect to RICs, BDCs
or SBICs; 

the exclusion of BDC common stock from certain market indices, such as what happened with respect to the Russell
indices and the Standard and Poor's indices, could reduce the ability of certain investment funds to own our common
stock and limit the number of owners of our common stock and otherwise negatively impact the market price of our
common stock; 

inability to obtain any exemptive relief that may be required by us in the future from the SEC; 

loss of our BDC or RIC status or any of the Funds' status as an SBIC; 

changes in our earnings or variations in our operating results; 

changes in the value of our portfolio of investments; 

any shortfall in our investment income or net investment income or any increase in losses from levels expected by
investors or securities analysts; 

loss of a major funding source; 

fluctuations in interest rates; 

the operating performance of companies comparable to us; 

departure of our key personnel; 

proposed, or completed, offerings of our securities, including classes other than our common stock; 

global or national credit market changes; and 

general economic trends and other external factors.

Provisions of the Maryland General Corporation Law and our articles of incorporation and bylaws could deter takeover attempts
and have an adverse impact on the price of our common stock.

       The Maryland General Corporation Law and our articles of incorporation and bylaws contain provisions that may have the effect of
discouraging, delaying or making difficult a change in control of our company or the removal of our incumbent directors. The existence of
these provisions, among others, may have a negative impact on the price of our common stock and may discourage third-party bids for
ownership of our company. These provisions may prevent any premiums being offered to you for our common stock.

The Notes are unsecured and therefore effectively subordinated to any current or future secured indebtedness, including
indebtedness under the Credit Facility.

       The Notes are not secured by any of our assets or any of the assets of our subsidiaries and rank equally in right of payment with all of
our existing and future unsubordinated, unsecured indebtedness. As a result, the Notes are effectively subordinated to any secured
indebtedness we or our subsidiaries have currently incurred and may incur in the future (or any indebtedness that is initially unsecured to
which we subsequently grant security) to the extent of the value of the assets securing such indebtedness. In any liquidation, dissolution,
bankruptcy or other similar proceeding, the holders of any of our existing or future secured indebtedness and the secured indebtedness of
our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their
indebtedness before the assets may be used to pay other creditors, including the holders of the Notes. As of December 31, 2018, we had
$301.0 million outstanding under the Credit Facility out of $705.0 million in commitments. The indebtedness under the Credit Facility is
senior to the Notes to the extent of the value of the assets securing such indebtedness.

The Notes are structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

       The Notes are obligations exclusively of Main Street Capital Corporation and not of any of our subsidiaries. None of our subsidiaries is
a guarantor of the Notes, and the Notes are not required to be guaranteed by any subsidiaries we may acquire or create in the future. In
addition, several of our subsidiaries, specifically the Funds, maintain significant indebtedness and as a result the Notes are structurally
subordinated to the indebtedness of these subsidiaries. For example, as of December 31, 2018, the Funds had collectively issued
$345.8 million of the current regulatory maximum of $350.0 million of SBA-guaranteed debentures, which are included in our
consolidated financial statements. The assets of such subsidiaries are not directly available to satisfy the claims of our creditors, including
holders of the Notes. See "Management's Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and
Capital Resources" for more detail on the SBA-guaranteed debentures.

       Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of other creditors of our subsidiaries
have priority over our equity interests in such subsidiaries (and therefore the claims of our creditors, including holders of the Notes) with
respect to the assets of such subsidiaries. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still
be effectively subordinated to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any
such subsidiary senior to our claims. Consequently, the Notes are structurally subordinated to all indebtedness, including the SBA-
guaranteed debentures, and other liabilities of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish. In
addition, our subsidiaries may incur substantial additional indebtedness in the future, all of which would be structurally senior to the Notes.

The Notes may or may not have an established trading market. If a trading market in the Notes is developed, it may not be
maintained.

       The Notes may or may not have an established trading market. If a trading market in the Notes is developed, it may not be maintained.
If the Notes are traded, they may trade at a discount to their initial offering price depending on prevailing interest rates, the market for
similar securities, our credit ratings, our financial condition or other relevant factors. Accordingly, we cannot assure you that a liquid
trading market has been or will develop for the Notes, that you will be able to sell your Notes at a particular time or that the price you
receive when you sell will be favorable. To the extent an active trading market does not develop or is not maintained, the liquidity and
trading price for the Notes may be harmed. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an
indefinite period of time.

A downgrade, suspension or withdrawal of the credit rating assigned by a rating agency to us or the Notes, if any, or change in
the debt markets could cause the liquidity or market value of the Notes to decline significantly.

       Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated
changes in our credit ratings will generally affect the market value of the Notes. These credit ratings may not reflect the potential impact of
risks relating to the structure or marketing of the Notes. Credit ratings are not a recommendation to buy, sell or hold any security, and may
be revised or withdrawn at any time by the issuing organization in its sole discretion. We undertake no obligation to maintain our credit
ratings or to advise holders of Notes of any changes in our credit ratings. The Notes are currently rated by Standard & Poor's Ratings
Services. There can be no assurance that our credit ratings will remain for any given period of time or that such credit ratings will not be
lowered or withdrawn entirely by the rating agency if in their judgment future circumstances relating to the basis of the credit ratings, such
as adverse changes in our company, so warrant. The conditions of the financial markets and prevailing interest rates have fluctuated in the
past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Notes.

The indentures under which the Notes were issued contain limited protection for holders of the Notes.

       The indentures under which the Notes were issued offer limited protection to holders of the Notes. The terms of the indentures and the
Notes do not restrict our or any of our subsidiaries' ability to engage in, or otherwise be a party to, a variety of corporate transactions,
circumstances or events that could have an adverse impact on investments in the Notes. In particular, the terms of the indentures and the
Notes do not place any restrictions on our or our subsidiaries' ability to:

•

•

•

•

•

•

•

issue securities or otherwise incur additional indebtedness or other obligations, including (1) any indebtedness or
other obligations that would be equal in right of payment to the Notes, (2) any indebtedness or other obligations that
would be secured and therefore rank effectively senior in right of payment to the Notes to the extent of the values of
the assets securing such debt, (3) indebtedness of ours that is guaranteed by one or more of our subsidiaries and
which therefore is structurally senior to the Notes and (4) securities, indebtedness or obligations issued or incurred by
our subsidiaries that would be senior to our equity interests in our subsidiaries and therefore rank structurally senior
to the Notes with respect to the assets of our subsidiaries, in each case other than an incurrence of indebtedness or
other obligation that would cause a violation of Section 18(a)(1)(A) as modified by Section 61(a)(1) of the 1940 Act
or any successor provisions, but giving effect, in each case, to any exemptive relief granted to us by the SEC
(currently, this provision generally prohibits us from making additional borrowings, including through the issuance
of additional debt or the sale of additional debt securities, unless our asset coverage, as defined in the 1940 Act,
equals at least 200% (or 150% if certain requirements are met) after such borrowings); 

pay dividends on, or purchase or redeem or make any payments in respect of, capital stock or other securities ranking
junior in right of payment to the Notes, including subordinated indebtedness; 

sell assets (other than certain limited restrictions on our ability to consolidate, merge or sell all or substantially all of
our assets); 

enter into transactions with affiliates; 

create liens (including liens on the shares of our subsidiaries) or enter into sale and leaseback transactions; 

make investments; or 

create restrictions on the payment of dividends or other amounts to us from our subsidiaries.

       Furthermore, the terms of the indentures and the Notes do not protect holders of the Notes in the event that we experience changes
(including significant adverse changes) in our financial condition, results of operations or credit ratings, if any, as they do not require that
we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow or liquidity.

45

Table of Contents

       Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the Notes may
have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with
respect to the Notes or negatively affecting the trading value of the Notes.

       Other debt we issue or incur in the future could contain more protections for its holders than the indentures and the Notes, including
additional covenants and events of default. For example, the indentures under which the Notes are issued do not contain cross-default
provisions that are contained in the Credit Facility. The issuance or incurrence of any such debt with incremental protections could affect
the market for and trading levels and prices of the Notes.

The optional redemption provision may materially adversely affect your return on the Notes.

       The Notes are redeemable in whole or in part upon certain conditions at any time or from time to time at our option. We may choose to
redeem the Notes at times when prevailing interest rates are lower than the interest rate paid on the Notes. In this circumstance, you may
not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the Notes being redeemed.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.

       We may not be able to repurchase the Notes upon certain change in control events described in the indentures under which the Notes
were issued (each, a "Change of Control Repurchase Event") because we may not have sufficient funds. Upon a Change of Control
Repurchase Event, holders of the Notes may require us to repurchase for cash some or all of the Notes at a repurchase price equal to 100%
of the aggregate principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but not including, the repurchase
date. The terms of our Credit Facility provide that certain change of control events will constitute an event of default thereunder entitling
the lenders to accelerate any indebtedness outstanding under our Credit Facility at that time and to terminate the Credit Facility. In addition,
the occurrence of a Change of Control Repurchase Event enabling the holders of the Notes to require the mandatory purchase of the Notes
would constitute an event of default under our Credit Facility entitling the lenders to accelerate any indebtedness outstanding under our
Credit Facility at that time and to terminate the Credit Facility. Our and our subsidiaries' future financing facilities may contain similar
restrictions and provisions. Our failure to purchase such tendered Notes upon the occurrence of such Change of Control Repurchase Event
would cause an event of default under the indentures governing the Notes and a cross-default under the agreements governing certain of
our other indebtedness, which may result in the acceleration of such indebtedness requiring us to repay that indebtedness immediately. If a
Change of Control Repurchase Event were to occur, we may not have sufficient funds to repay any such accelerated indebtedness.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Notes.

       As of December 31, 2018, we had approximately $1,006.8 million of principal indebtedness, including $301.0 million outstanding
under the Credit Facility, $345.8 million outstanding from SBA-guaranteed debentures, $175.0 million of the 4.50% Notes due 2019 and
$185.0 million of the 4.50% Notes due 2022 outstanding. Any default under the agreements governing our indebtedness, including a
default under the Credit Facility, under the Notes or under other indebtedness to which we may be a party that is not waived by the required
lenders or debt holders, and the remedies sought by the holders of such indebtedness could make us unable to pay principal, premium, if
any, and interest on the Notes and substantially decrease the market value of the Notes. If we are unable to generate sufficient cash flow and
are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or
if we otherwise fail to comply with the various covenants, including financial and operating covenants, in the instruments governing our
indebtedness, we could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the
holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and
unpaid interest, the lenders

46

Table of Contents

under the Credit Facility or other debt we may incur in the future could elect to terminate their commitments, cease making further loans
and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation. Our ability to generate
sufficient cash flow in the future is, to some extent, subject to general economic, financial, competitive, legislative and regulatory factors as
well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that
future borrowings will be available to us under the Credit Facility or otherwise, in an amount sufficient to enable us to meet our payment
obligations under the Notes and our other debt and to fund other liquidity needs.

       If our operating performance declines and we are not able to generate sufficient cash flow to service our debt obligations, we may in
the future need to refinance or restructure our debt, including the Notes, sell assets, reduce or delay capital investments, seek to raise
additional capital or seek to obtain waivers from the required lenders under the Credit Facility or the required holders of the Notes or other
debt that we may incur in the future to avoid being in default. If we are unable to implement one or more of these alternatives, we may not
be able to meet our payment obligations under the Notes and our other debt. If we breach our covenants under the Credit Facility, the Notes
or other debt and seek a waiver, we may not be able to obtain a waiver from the required lenders or debt holders. If this occurs, we would
be in default under the Credit Facility, the Notes or other debt, the lenders or debt holders could exercise their rights as described above,
and we could be forced into bankruptcy or liquidation. If we are unable to repay debt, lenders having secured obligations could proceed
against the collateral securing the debt. Because the Credit Facility has, and any future credit facilities will likely have, customary cross-
default provisions, if the indebtedness under the Notes, the Credit Facility or under any future credit facility is accelerated, we may be
unable to repay or finance the amounts due.

We may in the future determine to issue preferred stock, which could adversely affect the market value of our common stock.

       The issuance of shares of preferred stock with dividend or conversion rights, liquidation preferences or other economic terms favorable
to the holders of preferred stock could adversely affect the market price for our common stock by making an investment in the common
stock less attractive. In addition, the dividends on any preferred stock we issue must be cumulative. Payment of dividends and repayment of
the liquidation preference of preferred stock must take preference over any dividends or other payments to our common stockholders, and
holders of preferred stock are not subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in
excess of their stated preference (other than convertible preferred stock that converts into common stock). In addition, under the 1940 Act,
preferred stock constitutes a "senior security" for purposes of the asset coverage test.

Item 1B.    Unresolved Staff Comments 

       None.

Item 2.    Properties 

       We do not own any real estate or other physical properties materially important to our operations. Currently, we lease office space in
Houston, Texas for our corporate headquarters.

Item 3.    Legal Proceedings 

       We may, from time to time, be involved in litigation arising out of our operations in the normal course of business or otherwise.
Furthermore, third parties may seek to impose liability on us in connection with the activities of our portfolio companies. While the
outcome of any current legal proceedings cannot at this time be predicted with certainty, we do not expect any current matters will
materially affect our financial condition or results of operations; however, there can be no assurance whether any pending legal proceedings
will have a material adverse effect on our financial condition or results of operations in any future reporting period.

COMMON STOCK, HOLDERS AND DISTRIBUTIONS

       Our common stock is traded on the New York Stock Exchange ("NYSE") under the symbol "MAIN." Prior to October 14, 2010, our
common stock was traded on the NASDAQ Global Select Market under the same symbol "MAIN." Our common stock began trading on
the NASDAQ Global Select Market on October 5, 2007. Prior to that date, there was no established public trading market for our common
stock.

       On February 27, 2019, there were approximately 346 holders of record of the common stock which did not include stockholders for
whom shares are held in "nominee" or "street name."

       Shares of BDCs may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that
our shares of common stock will trade at a discount from net asset value per share or at premiums that are unsustainable over the long term
are separate and distinct from the risk that our net asset value per share will decrease. It is not possible to predict whether our common stock
will trade at, above, or below net asset value per share. Since our IPO in October 2007, our shares of common stock have traded at prices
both less than and exceeding our net asset value per share.

       We currently pay regular monthly dividends and semiannual supplemental dividends to our stockholders. Our monthly dividends, if
any, will be determined by our Board of Directors on a quarterly basis. Our semiannual supplemental dividends, if any, will also be
determined by our Board of Directors on a periodic basis. During 2018, we paid supplemental dividends of $0.275 per share in each of June
and December 2018, regular monthly dividends of $0.190 per share for each month of January through September 2018, regular monthly
dividends of $0.195 per share for each month of October through December 2018, with such dividends totaling $2.845 per share. The 2018
regular monthly dividends of $2.295 per share, represent a 2.7% increase from the regular monthly dividends paid per share for the year
ended 2017. For tax purposes, the 2018 dividends, which included the effects of dividends on an accrual basis, total $2.85 per share and
were comprised of (i) ordinary income totaling approximately $2.270 per share, (ii) long term capital gain totaling approximately $0.375
per share, and (iii) qualified dividend income totaling approximately $0.205 per share. As we have previously discussed, it is our current
intention to fully absorb our semi-annual supplemental dividends into our regular monthly dividends, and in the process maintain and grow
our total combined dividends, by gradually reducing our semi-annual supplemental dividends while increasing our regular monthly
dividends over multiple years beginning in 2019.

       In accordance with the IRC sections 871(k) and 881(e), the following percentages represent the portion of our dividends that constitute
interest related dividends and short-term capital gains dividends for non-U.S. residents and foreign corporations. Including the long-term
capital gains discussed above, the following percentages represent the total dividends which are exempt from U.S. withholding tax.

       To the extent non-U.S. resident taxes were withheld on ordinary dividends distributed, this information may be considered in
connection with any claims for refund of such taxes to be filed by the non-U.S. resident stockholder with the Internal Revenue Service.

       To obtain and maintain RIC tax treatment, we must, among other things, distribute at least 90% of our net ordinary taxable income and
realized net short-term capital gains in excess of realized net long-term capital losses, if any. We will be subject to a 4% non-deductible
U.S. federal excise tax on certain undistributed taxable income unless we distribute in a timely manner an amount at least equal to the sum
of (1) 98% of our net ordinary taxable income for each calendar year, (2) 98.2% of our capital gain net income for the one-year period
ending December 31 in that calendar year and (3) any taxable income recognized, but not distributed, in preceding years on which we paid
no U.S. federal income tax. Dividends declared and paid by us in a year will generally differ from taxable income for that year, as such
dividends may include the distribution of current year taxable income, less amounts carried over into the following year, and the
distribution of prior year taxable income carried over into and distributed in the current year. For amounts we carry over into the following
year, we will be required to pay the 4% U.S. federal excise tax on the excess of 98% of our annual investment company taxable income and
98.2% of our capital gain net income over our distributions for the year. We may retain for investment some or all of our net capital gains
(i.e., realized net long-term capital gains in excess of realized net short-term capital losses) and treat such amounts as deemed distributions
to our stockholders. If we do this, our stockholders will be treated as if they had received actual distributions of the capital gains we
retained and then reinvested the net after-tax proceeds in our common stock. In general, our stockholders also would be eligible to claim a
tax credit (or, in certain circumstances, a tax refund) equal to their allocable shares of the tax we paid on the capital gains deemed
distributed to them. We can offer no assurance that we will achieve results that will permit the payment of any cash distributions and, if we
issue senior securities, we may be prohibited from making distributions if doing so causes us to fail to maintain the asset coverage ratios
stipulated by the 1940 Act or if distributions are limited by the terms of any of our borrowings.

       We may distribute taxable dividends that are payable in part in our stock. Under certain applicable provisions of the Code and the
Treasury regulations, distributions payable by us in cash or in shares of stock (at the stockholders election) would satisfy the Annual
Distribution Requirement. The Internal Revenue Service has issued guidance providing that a dividend payable in stock or in cash at the
election of the stockholders will be treated as a taxable dividend eligible for the dividends paid deduction provided that at least 20% of the
total dividend is payable in cash and certain other requirements are satisfied. Taxable stockholders receiving such dividends will be
required to include the full amount of the dividend as ordinary income (or as long-term capital gain to the extent such dividend is properly
reported as a capital gain dividend), to the extent of our current and accumulated earnings and profits for U.S. federal income tax purposes.
As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash received. If a U.S.
stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in
income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-
U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such
dividend that is payable in stock. In addition, if a significant number of our stockholders determine to sell shares of our stock in order to pay
taxes owed on dividends, it may put downward pressure on the trading price of our stock.

       We have adopted a dividend reinvestment plan ("DRIP") that provides for the reinvestment of dividends on behalf of our stockholders,
unless a stockholder has elected to receive dividends in cash. As a result, if we declare a cash dividend, our stockholders who have not
"opted out" of the DRIP by the dividend record date will have their cash dividend automatically reinvested into additional shares of MSCC
common stock. The share requirements of the DRIP may be satisfied through the issuance of new shares of common stock or through open
market purchases of common stock by the DRIP plan administrator. Newly issued shares will be valued based upon the final closing price
of MSCC's common stock on a valuation date determined for each dividend by our Board of Directors. Shares purchased in the open
market to satisfy the DRIP

49

Table of Contents

requirements will be valued based upon the average price of the applicable shares purchased by the DRIP plan administrator, before any
associated brokerage or other costs. Our DRIP is administered by its transfer agent on behalf of our record holders and participating
brokerage firms. Brokerage firms and other financial intermediaries may decide not to participate in our DRIP but may provide a similar
dividend reinvestment plan for their clients.

SALES OF UNREGISTERED SECURITIES

       During the year ended December 31, 2018, we issued a total of 394,403 shares of our common stock under the DRIP. These issuances
were not subject to the registration requirements of the Securities Act of 1933, as amended. The aggregate value of the shares of our
common stock issued under the DRIP during 2018 was approximately $14.9 million.

(2) Weighted-average effective yield is calculated based on our debt investments at the end of each period and includes
amortization of deferred debt origination fees and accretion of original issue discount, but excludes liquidation fees
payable upon repayment and any debt investments on non-accrual status. The weighted-average annual effective yield
is higher than what an investor in shares of our common stock will realize on its investment because it does not reflect
any debt investments on non-accrual status, our expenses or any sales load paid by an investor. For information on our
investments on non-accrual status, see "Management's Discussion and Analysis of Financial Condition and Results of
Operations — Portfolio Asset Quality".

Including investments on non-accrual status, the weighted-average effective yield for LMM, Middle Market, and
Private Loan debt investments was 11.3%, 9.5%, and 9.8%, respectively, as of December 31, 2018. 

Total investment return is based on the purchase of stock at the current market price on the first day and a sale at the
current market price on the last day of each period reported on the table and assumes reinvestment of dividends at
prices obtained by our dividend reinvestment plan during the period. The return does not reflect any sales load that

Total return is based on change in net asset value and was calculated using the sum of ending net asset value plus
dividends to stockholders and other non-operating changes during the period, as divided by the beginning net asset
value. Non-operating changes include any items that affect net asset value other than the net increase in net assets
resulting from operations, such as the effects of stock offerings, shares issued under the DRIP and equity incentive
plans and other miscellaneous items.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations 

       The following discussion should be read in conjunction with our consolidated financial statements and the notes thereto included
elsewhere in this Annual Report on Form 10-K.

       Statements we make in the following discussion which express a belief, expectation or intention, as well as those that are not historical
fact, are forward-looking statements that are subject to risks, uncertainties and assumptions. Our actual results, performance or
achievements, or industry results, could differ materially from those we express in the following discussion as a result of a variety of
factors, including the risks and uncertainties we have referred to under the headings "Cautionary Statement Concerning Forward-Looking
Statements" and "Risk Factors" in Part I of this report.

ORGANIZATION

       Main Street Capital Corporation ("MSCC") is a principal investment firm primarily focused on providing customized debt and equity
financing to lower middle market ("LMM") companies and debt capital to middle market ("Middle Market") companies. The portfolio
investments of MSCC and its consolidated subsidiaries are typically made to support management buyouts, recapitalizations, growth
financings, refinancings and acquisitions of companies that operate in a variety of industry sectors. MSCC seeks to partner with
entrepreneurs, business owners and management teams and generally provides "one stop" financing alternatives within its LMM portfolio.
MSCC and its consolidated subsidiaries invest primarily in secured debt investments, equity investments, warrants and other securities of
LMM companies based in the United States and in secured debt investments of Middle Market companies generally headquartered in the
United States.

       MSCC was formed in March 2007 to operate as an internally managed business development company ("BDC") under the Investment
Company Act of 1940, as amended (the "1940 Act"). MSCC wholly owns several investment funds, including Main Street Mezzanine
Fund, LP ("MSMF"), Main Street Capital II, LP ("MSC II") and Main Street Capital III, LP ("MSC III" and, collectively with MSMF and
MSC II, the "Funds"), and each of their general partners. The Funds are each licensed as a Small Business Investment Company ("SBIC")
by the United States Small Business Administration ("SBA"). Because MSCC is internally managed, all of the executive officers and other
employees are employed by MSCC. Therefore, MSCC does not pay any external investment advisory fees, but instead directly incurs the
operating costs associated with employing investment and portfolio management professionals.

       MSC Adviser I, LLC (the "External Investment Manager") was formed in November 2013 as a wholly owned subsidiary of MSCC to
provide investment management and other services to parties other than MSCC and its subsidiaries or their portfolio companies ("External
Parties") and receives fee income for such services. MSCC has been granted no-action relief by the Securities and Exchange Commission
("SEC") to allow the External Investment Manager to register as a registered investment adviser under the Investment Advisers Act of
1940, as amended. Since the External Investment Manager conducts all of its investment management activities for External Parties, it is
accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated
financial statements.

       MSCC has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M
of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSCC generally will not pay corporate-level U.S. federal
income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

       MSCC has certain direct and indirect wholly owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries").
The primary purpose of the Taxable Subsidiaries is to permit MSCC to hold equity investments in portfolio companies which are "pass-
through" entities for tax purposes.

       Unless otherwise noted or the context otherwise indicates, the terms "we," "us," "our," the "Company" and "Main Street" refer to
MSCC and its consolidated subsidiaries, which include the Funds and the Taxable Subsidiaries.

OVERVIEW

       Our principal investment objective is to maximize our portfolio's total return by generating current income from our debt investments
and capital appreciation from our equity and equity-related investments, including warrants, convertible securities and other rights to
acquire equity securities in a portfolio company. Our LMM companies generally have annual revenues between $10 million and
$150 million, and our LMM portfolio investments generally range in size from $5 million to $50 million. Our Middle Market investments
are made in businesses that are generally larger in size than our LMM portfolio companies, with annual revenues typically between
$150 million and $1.5 billion, and our Middle Market investments generally range in size from $3 million to $20 million. Our private loan
("Private Loan") portfolio investments are primarily debt securities in privately held companies which have been originated through
strategic relationships with other investment funds on a collaborative basis. Private Loan investments are typically similar in size, structure,
terms and conditions to investments we hold in our LMM portfolio and Middle Market portfolio.

       We seek to fill the financing gap for LMM businesses, which, historically, have had limited access to financing from commercial banks
and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM
companies while also negotiating favorable transaction terms and equity participations. Our ability to invest across a company's capital
structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options, or a
"one stop" financing solution. Providing customized, "one stop" financing solutions is important to LMM portfolio companies. We
generally seek to partner directly with entrepreneurs, management teams and business owners in making our investments. Our LMM
portfolio debt investments are generally secured by a first lien on the assets of the portfolio company and typically have a term of between
five and seven years from the original investment date.

       Our Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing debt
securities in privately held companies that are generally larger in size than the companies included in our LMM portfolio. Our Middle
Market portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and
typically have an expected duration of between three and seven years from the original investment date.

       Our Private Loan portfolio investments are primarily debt securities in privately held companies which have been originated through
strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt markets as "club deals."
Private Loan investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and
Middle Market portfolio. Our Private Loan portfolio debt investments are generally secured by either a first or second priority lien on the
assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

       Our other portfolio ("Other Portfolio") investments primarily consist of investments which are not consistent with the typical profiles
for our LMM, Middle Market or Private Loan portfolio investments, including investments which may be managed by third parties. In our
Other Portfolio, we may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in
other investment companies or private funds.

       Our external asset management business is conducted through the External Investment Manager. The External Investment Manager
earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the
performance of the funds managed. We have entered into an agreement with the External Investment Manager to share employees in
connection with its asset management business generally, and specifically for its relationship with HMS Income Fund, Inc. ("HMS
Income"). Through this agreement, we share employees with the External Investment Manager, including their related infrastructure,
business relationships, management expertise and capital raising capabilities.

       The following tables provide a summary of our investments in the LMM, Middle Market and Private Loan portfolios as of

At December 31, 2018, we had equity ownership in approximately 99% of our LMM portfolio companies, and the
average fully diluted equity ownership in those portfolio companies was approximately 40%. 

The weighted average annual effective yields were computed using the effective interest rates for all debt
investments at cost as of December 31, 2018, including amortization of deferred debt origination fees and accretion
of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt
investments on non-accrual status. Weighted average annual effective yield is higher than what an investor in
shares of our common stock will realize on its investment because it does not reflect our expenses or any sales load
paid by an investor. 

The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the
Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including two
LMM portfolio companies, one Middle Market portfolio company and four Private Loan portfolio companies, as
EBITDA is not a meaningful valuation metric for our investments in these portfolio companies, and those portfolio
companies whose primary purpose is to own real estate.

effective yield is higher than what an investor in shares of our common stock will realize on its investment because
it does not reflect our expenses or any sales load paid by an investor.

(c)

The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the
Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including six
LMM portfolio companies, one Middle Market portfolio company and three Private Loan portfolio companies, as
EBITDA is not a meaningful valuation metric for our investments in these portfolio companies, and those portfolio
companies whose primary purpose is to own real estate.

       As of December 31, 2018, we had Other Portfolio investments in eleven companies, collectively totaling approximately $108.3 million
in fair value and approximately $116.0 million in cost basis and which comprised approximately 4.4% of our Investment Portfolio (as
defined in "Critical Accounting Policies — Basis of Presentation" below) at fair value. As of December 31, 2017, we had Other Portfolio
investments in eleven companies, collectively totaling approximately $104.6 million in fair value and approximately $109.4 million in cost
basis and which comprised approximately 4.8% of our Investment Portfolio at fair value.

       As previously discussed, the External Investment Manager is a wholly owned subsidiary that is treated as a portfolio investment. As of
December 31, 2018, there was no cost basis in this investment and the investment had a fair value of approximately $65.7 million, which
comprised approximately 2.7% of our Investment Portfolio at fair value. As of December 31, 2017, there was no cost basis in this
investment and the investment had a fair value of approximately $41.8 million, which comprised approximately 1.9% of our Investment
Portfolio at fair value.

       Our portfolio investments are generally made through MSCC and the Funds. MSCC and the Funds share the same investment
strategies and criteria, although they are subject to different regulatory regimes. An investor's return in MSCC will depend, in part, on the
Funds' investment returns as they are wholly owned subsidiaries of MSCC.

       The level of new portfolio investment activity will fluctuate from period to period based upon our view of the current economic
fundamentals, our ability to identify new investment opportunities that meet our investment criteria, and our ability to consummate the
identified opportunities. The level of new investment activity, and associated interest and fee income, will directly impact future investment
income. In addition, the level of dividends paid by portfolio companies and the portion of our portfolio debt investments on non-accrual
status will directly impact future investment income. While we intend to grow our portfolio and our investment income over the long term,
our growth and our operating results may be more limited during depressed economic periods. However, we intend to appropriately manage
our cost structure and liquidity position based on applicable economic conditions and our investment outlook. The level of realized gains or
losses and unrealized appreciation or depreciation on our investments will also fluctuate depending upon portfolio activity, economic
conditions and the performance of our individual portfolio companies. The changes in realized gains and losses and unrealized appreciation
or depreciation could have a material impact on our operating results.

       Because we are internally managed, we do not pay any external investment advisory fees, but instead directly incur the operating costs
associated with employing investment and portfolio management professionals. We believe that our internally managed structure provides
us with a beneficial operating expense structure when compared to other publicly traded and privately held investment firms which are
externally managed, and our internally managed structure allows us the opportunity to leverage our non-interest operating expenses as we
grow our Investment Portfolio. For the years ended December 31, 2018 and 2017, the ratio of our total operating expenses, excluding
interest expense, as a percentage of our quarterly average total assets was 1.4% and 1.6%, respectively.

       During May 2012, we entered into an investment sub-advisory agreement with HMS Adviser, LP ("HMS Adviser"), which is the
investment advisor to HMS Income, a non-listed BDC, to provide certain investment

57

Table of Contents

advisory services to HMS Adviser. In December 2013, after obtaining required no-action relief from the SEC to allow us to own a
registered investment adviser, we assigned the sub-advisory agreement to the External Investment Manager since the fees received from
such arrangement could otherwise have negative consequences on our ability to meet the source-of-income requirement necessary for us to
maintain our RIC tax treatment. Under the investment sub-advisory agreement, the External Investment Manager is entitled to 50% of the
base management fee and the incentive fees earned by HMS Adviser under its advisory agreement with HMS Income. The External
Investment Manager has conditionally agreed to waive the historical incentive fees otherwise earned. During the years ended December 31,
2018, 2017 and 2016, the External Investment Manager earned $11.6 million, $10.9 million and $9.5 million, respectively, of management
fees (net of fees waived, if any) under the sub-advisory agreement with HMS Adviser.

       During April 2014, we received an exemptive order from the SEC permitting co-investments by us and HMS Income in certain
negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. We have made, and in the future intend to
continue to make, such co-investments with HMS Income in accordance with the conditions of the order. The order requires, among other
things, that we and the External Investment Manager consider whether each such investment opportunity is appropriate for HMS Income
and, if it is appropriate, to propose an allocation of the investment opportunity between us and HMS Income. Because the External
Investment Manager may receive performance-based fee compensation from HMS Income, this may provide it an incentive to allocate
opportunities to HMS Income instead of us. However, both we and the External Investment Manager have policies and procedures in place
to manage this conflict.

CRITICAL ACCOUNTING POLICIES

Basis of Presentation

       Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of
America ("U.S. GAAP"). For each of the periods presented herein, our consolidated financial statements include the accounts of MSCC
and its consolidated subsidiaries. The Investment Portfolio, as used herein, refers to all of our investments in LMM portfolio companies,
investments in Middle Market portfolio companies, Private Loan portfolio investments, Other Portfolio investments, and the investment in
the External Investment Manager. Our results of operations and cash flows for the years ended December 31, 2018, 2017 and 2016 and
financial position as of December 31, 2018 and 2017, are presented on a consolidated basis. The effects of all intercompany transactions
between us and our consolidated subsidiaries have been eliminated in consolidation. Certain reclassifications have been made to prior
period balances to conform with the current presentation.

       We are an investment company following the accounting and reporting guidance in Financial Accounting Standards Board ("FASB")
Accounting Standards Codification ("ASC") 946, Financial Services — Investment Companies ("ASC 946"). Under ASC 946, we are
precluded from consolidating other entities in which we have equity investments, including those in which we have a controlling interest,
unless the other entity is another investment company. An exception to this general principle in ASC 946 occurs if we hold a controlling
interest in an operating company that provides all or substantially all of its services directly to us or to any of our portfolio companies.
Accordingly, as noted above, our consolidated financial statements include the financial position and operating results for the Funds and
the Taxable Subsidiaries. We have determined that all of our portfolio investments do not qualify for this exception, including the
investment in the External Investment Manager. Therefore, our Investment Portfolio is carried on the consolidated balance sheet at fair
value with any adjustments to fair value recognized as "Net Unrealized Appreciation (Depreciation)" on the consolidated statements of
operations until the investment is realized, usually upon exit, resulting in any gain or loss being recognized as a "Net Realized Gain
(Loss)."

58

Table of Contents

Investment Portfolio Valuation

       The most significant determination inherent in the preparation of our consolidated financial statements is the valuation of our
Investment Portfolio and the related amounts of unrealized appreciation and depreciation. As of both December 31, 2018 and 2017, our
Investment Portfolio valued at fair value represented approximately 96% of our total assets. We are required to report our investments at
fair value. We follow the provisions of FASB ASC 820, Fair Value Measurements and Disclosures ("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. ASC 820 requires us to assume that the portfolio investment
is to be sold in the principal market to independent market participants, which may be a hypothetical market. Market participants are
defined as buyers and sellers in the principal market that are independent, knowledgeable and willing and able to transact. See
"Note B.1. — Valuation of the Investment Portfolio" in the notes to consolidated financial statements for a detailed discussion of our
investment portfolio valuation process and procedures.

       Due to the inherent uncertainty in the valuation process, our determination of fair value for our Investment Portfolio may differ
materially from the values that would have been determined had a ready market for the securities existed. In addition, 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 these investments to be materially different than the valuations currently assigned. We determine the fair
value of each individual investment and record changes in fair value as unrealized appreciation or depreciation.

       Our Board of Directors has the final responsibility for overseeing, reviewing and approving, in good faith, our determination of the fair
value for our Investment Portfolio and our valuation procedures, consistent with 1940 Act requirements. We believe our Investment
Portfolio as of December 31, 2018 and 2017 approximates fair value as of those dates based on the markets in which we operate and other
conditions in existence on those reporting dates.

Revenue Recognition

Interest and Dividend Income

       We record interest and dividend income on the accrual basis to the extent amounts are expected to be collected. Dividend income is
recorded as dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a
distribution. In accordance with our valuation policies, we evaluate accrued interest and dividend income periodically for collectability.
When a loan or debt security becomes 90 days or more past due, and if we otherwise do not expect the debtor to be able to service all of its
debt or other obligations, we will generally place the loan or debt security on non-accrual status and cease recognizing interest income on
that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt
security's status significantly improves regarding the debtor's ability to service the debt or other obligations, or if a loan or debt security is
sold or written off, we remove it from non-accrual status.

Fee Income

       We may periodically provide services, including structuring and advisory services, to our portfolio companies or other third parties.
For services that are separately identifiable and evidence exists to substantiate fair value, fee income is recognized as earned, which is
generally when the investment or other applicable transaction closes. Fees received in connection with debt financing transactions for
services that do not meet these criteria are treated as debt origination fees and are deferred and accreted into income over the life of the
financing.

59

Table of Contents

Payment-in-Kind ("PIK") Interest and Cumulative Dividends

       We hold certain debt and preferred equity instruments in our Investment Portfolio that contain PIK interest and cumulative dividend
provisions. The PIK interest, computed at the contractual rate specified in each debt agreement, is periodically added to the principal
balance of the debt and is recorded as interest income. Thus, the actual collection of this interest may be deferred until the time of debt
principal repayment. Cumulative dividends are recorded as dividend income, and any dividends in arrears are added to the balance of the
preferred equity investment. The actual collection of these dividends in arrears may be deferred until such time as the preferred equity is
redeemed or sold. To maintain RIC tax treatment (as discussed below), these non-cash sources of income may need to be paid out to
stockholders in the form of distributions, even though we may not have collected the PIK interest and cumulative dividends in cash. We
stop accruing PIK interest and cumulative dividends and write off any accrued and uncollected interest and dividends in arrears when we
determine that such PIK interest and dividends in arrears are no longer collectible. For the years ended December 31, 2018, 2017 and 2016,
(i) approximately 1.0%, 2.4%, and 3.6%, respectively, of our total investment income was attributable to PIK interest income not paid
currently in cash and (ii) approximately 1.0%, 1.6%, and 1.2%, respectively, of our total investment income was attributable to cumulative
dividend income not paid currently in cash.

Share-Based Compensation

       We account for our share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation — Stock
Compensation. Accordingly, for restricted stock awards, we measure the grant date fair value based upon the market price of our common
stock on the date of the grant and amortize the fair value of the awards as share-based compensation expense over the requisite service
period, which is generally the vesting term.

       We have also adopted Accounting Standards Update ("ASU") 2016-09, Compensation — Stock Compensation: Improvements to
Employee Share-Based Payment Accounting, which requires that all excess tax benefits and tax deficiencies (including tax benefits of
dividends on share-based payment awards) be recognized as income tax expense or benefit in the income statement and not delay
recognition of a tax benefit until the tax benefit is realized through a reduction to taxes payable. The tax effects of exercised or vested
awards should be treated as discrete items in the reporting period in which they occur. Additionally, we have elected to account for
forfeitures as they occur.

Income Taxes

       MSCC has elected to be treated for U.S. federal income tax purposes as a RIC. MSCC's taxable income includes the taxable income
generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as disregarded entities for tax purposes. As a
RIC, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that
MSCC distributes to its stockholders. MSCC must generally distribute at least 90% of its "investment company taxable income" (which is
generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and
90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC
status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be
distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of
(i) filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close
of the year in which such taxable income was generated.

       The Taxable Subsidiaries primarily hold certain portfolio investments for us. The Taxable Subsidiaries permit us to hold equity
investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the "source-of-
income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with us for U.S. GAAP
financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in our consolidated

60

Table of Contents

financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated with MSCC for
income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their ownership of certain
portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or loss, due to
temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at their normal corporate
tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the Taxable
Subsidiaries are reflected in our consolidated financial statements.

       The External Investment Manager is an indirect wholly owned subsidiary of MSCC owned through a Taxable Subsidiary and is a
disregarded entity for tax purposes. The External Investment Manager has entered into a tax sharing agreement with its Taxable Subsidiary
owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a consolidated
subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its Taxable Subsidiary
owner, for its stand-alone financial reporting purposes the External Investment Manager is treated as if it is taxed at normal corporate tax
rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. The income tax expense, or
benefit, if any, and the related tax assets and liabilities, of the External Investment Manager are reflected in the External Investment
Manager's separate financial statements.

       In December 2017, the "Tax Cuts and Jobs Act" legislation was enacted. The Tax Cuts and Jobs Act includes significant changes to the
U.S. corporate tax system, including a U.S. federal corporate income tax rate reduction from 35% to 21% and other changes. ASC 740,
Income Taxes, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the
legislation was enacted. As such, we have accounted for the tax effects as a result of the enactment of the Tax Cuts and Jobs Act beginning
with the period ended December 31, 2017.

       The Taxable Subsidiaries and the External Investment Manager use the liability method in accounting for income taxes. Deferred tax
assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the
consolidated financial statements, using statutory tax rates in effect for the year in which the temporary differences are expected to reverse.
A valuation allowance is provided, if necessary, against deferred tax assets when it is more likely than not that some portion or all of the
deferred tax asset will not be realized.

       Taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the
recognition of income and expenses. Taxable income generally excludes net unrealized appreciation or depreciation, as investment gains or
losses are not included in taxable income until they are realized.

INVESTMENT PORTFOLIO COMPOSITION

       Our LMM portfolio investments primarily consist of secured debt, equity warrants and direct equity investments in privately held,
LMM companies based in the United States. Our LMM portfolio companies generally have annual revenues between $10 million and
$150 million, and our LMM investments generally range in size from $5 million to $50 million. The LMM debt investments are typically
secured by either a first or second priority lien on the assets of the portfolio company, can include either fixed or floating rate terms and
generally have a term of between five and seven years from the original investment date. In most LMM portfolio investments, we receive
nominally priced equity warrants and/or make direct equity investments in connection with a debt investment.

       Our Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing debt
securities in privately held companies based in the United States that are generally larger in size than the companies included in our LMM
portfolio. Our Middle Market portfolio companies generally have annual revenues between $150 million and $1.5 billion, and our Middle
Market investments generally range in size from $3 million to $20 million. Our Middle Market portfolio debt

61

Table of Contents

investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of
between three and seven years from the original investment date.

       Our Private Loan portfolio investments are primarily debt securities in privately held companies which have been originated through
strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt markets as "club deals."
Private Loan investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and
Middle Market portfolio. Our Private Loan portfolio debt investments are generally secured by either a first or second priority lien on the
assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

       Our Other Portfolio investments primarily consist of investments which are not consistent with the typical profiles for LMM, Middle
Market and Private Loan portfolio investments, including investments which may be managed by third parties. In the Other Portfolio, we
may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in other investment
companies or private funds.

       Our external asset management business is conducted through the External Investment Manager. The External Investment Manager
earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the
performance of the funds managed. We have entered into an agreement with the External Investment Manager to share employees in
connection with its asset management business generally, and specifically for its relationship with HMS Income. Through this agreement,
we share employees with the External Investment Manager, including their related infrastructure, business relationships, management
expertise and capital raising capabilities, and we allocate the related expenses to the External Investment Manager pursuant to the sharing
agreement. Our total expenses for the years ended December 31, 2018, 2017 and 2016 are net of expenses allocated to the External
Investment Manager of $6.8 million, $6.4 million and $5.1 million, respectively. The External Investment Manager earns management fees
based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the performance of the funds
managed. The total contribution of the External Investment Manager to our net investment income consists of the combination of the
expenses allocated to the External Investment Manager and the dividend income received from the External Investment Manager. For the
years ended December 31, 2018, 2017 and 2016, the total contribution to our net investment income was $10.6 million, $9.4 million and
$7.9 million, respectively.

       The following tables summarize the composition of our total combined LMM portfolio investments, Middle Market portfolio
investments and Private Loan portfolio investments at cost and fair value by type of investment as a percentage of the total combined LMM
portfolio investments, Middle Market portfolio investments and Private Loan portfolio investments as of December 31, 2018 and 2017 (this
information excludes the Other Portfolio investments and the External Investment Manager).

       Our LMM portfolio investments, Middle Market portfolio investments and Private Loan portfolio investments carry a number of risks
including: (1) investing in companies which may have limited operating histories and financial resources; (2) holding investments that
generally are not publicly traded and which may be subject to legal and other restrictions on resale; and (3) other risks common to investing
in below investment grade debt and equity investments in our Investment Portfolio. Please see "Risk Factors — Risks Related to Our
Investments" for a more complete discussion of the risks involved with investing in our Investment Portfolio.

PORTFOLIO ASSET QUALITY

       We utilize an internally developed investment rating system to rate the performance of each LMM portfolio company and to monitor
our expected level of returns on each of our LMM investments in relation to our expectations for the portfolio company. The investment
rating system takes into consideration various factors, including each investment's expected level of returns, the collectability of our debt
investments and the ability to receive a return of the invested capital in our equity investments, comparisons to competitors and other
industry participants, the portfolio company's future outlook and other factors that are deemed to be significant to the portfolio company.

       As of December 31, 2018, our total Investment Portfolio had six investments on non-accrual status, which comprised approximately
1.3% of its fair value and 3.9% of its cost. As of December 31, 2017, our total Investment Portfolio had five investments on non-accrual
status, which comprised approximately 0.2% of its fair value and 2.3% of its cost.

       The operating results of our portfolio companies are impacted by changes in the broader fundamentals of the United States economy.
In the event that the United States economy contracts, it is likely that the financial results of small to mid-sized companies, like those in
which we invest, could experience deterioration or limited growth from current levels, which could ultimately lead to difficulty in meeting
their debt service requirements, to an increase in defaults on our debt investments or in realized losses on our investments and to difficulty
in maintaining historical dividend payment rates and unrealized appreciation on our equity investments. Consequently, we can provide no
assurance that the performance of certain portfolio companies will not be negatively impacted by economic cycles or other conditions,
which could also have a negative impact on our future results.

Distributable net investment income is net investment income as determined in accordance with U.S. GAAP,
excluding the impact of share-based compensation expense which is non-cash in nature. We believe presenting
distributable net investment income and related per share amounts is useful and appropriate supplemental
disclosure of information for analyzing our financial performance since share-based compensation does not require
settlement in cash. However, distributable net investment income is a non-U.S. GAAP measure and should not be
considered as a replacement to net investment income and other earnings measures presented in accordance with
U.S. GAAP. Instead, distributable net investment income should be reviewed only in connection with such
U.S. GAAP measures in analyzing our financial performance. A reconciliation of net investment income in
accordance with U.S. GAAP to distributable net investment income is presented in the table above.

Investment Income

       For the year ended December 31, 2018, total investment income was $233.4 million, a 13% increase over the $205.7 million of total
investment income for the corresponding period of 2017. This comparable period increase was principally attributable to (i) a $15.2 million
net increase in interest income primarily related to higher average levels of Investment Portfolio debt investments and an increase in their
average effective

yields, partially offset by decreases in interest income associated with activity from portfolio companies that is considered to be less
consistent on a recurring basis or non-recurring and prepayment, repricing and other activities involving existing Investment Portfolio debt
investments, (ii) a $11.8 million increase in dividend income from Investment Portfolio equity investments and (iii) a $0.7 million increase
in fee income. The $27.6 million increase in total investment income in the year ended December 31, 2018 includes $6.3 million related to
elevated dividend income activity from certain Investment Portfolio equity investments that is considered to be less consistent on a
recurring basis or non-recurring, partially offset by (i) a decrease of $2.7 million related to interest income activity from portfolio
companies that is considered to be less consistent on a recurring basis or non-recurring and (ii) a decrease of $2.5 million related to lower
accelerated prepayment, repricing and other activity for certain Investment Portfolio debt investments, in each case when compared to the
same period in 2017.

Expenses

       For the year ended December 31, 2018, total expenses increased to $76.7 million from $70.4 million for the corresponding period of
2017. This comparable period increase in operating expenses was principally attributable to (i) a $7.0 million increase in interest expense,
primarily due to an $8.0 million increase as a result of the issuance of our 4.50% Notes due 2022 in November 2017, with the remainder of
the difference from prior year due to the higher average balance of SBIC debentures outstanding and an increase in both the average
balance outstanding and the interest rate on our multi-year revolving credit facility (the "Credit Facility"), with these increases partially
offset by a decrease from the redemption of the 6.125% Notes effective April 1, 2018, and (ii) a $0.4 million increase in compensation
expense related to increases in the number of personnel, base compensation levels and incentive compensation accruals, with these
increases partially offset by (i) a $0.9 million decrease in share-based compensation expense, (ii) a decrease of $0.9 million related to an
additional decrease in incentive compensation accruals and (iii) a $0.4 million increase in the expenses allocated to the External Investment
Manager as a result of elevated non-recurring strategic activities at the External Investment Manager during the year ended December 31,
2018. The $0.4 million increase in compensation expense is after (i) a $1.5 million decrease that is considered to be a one-time non-
recurring benefit due to the conversion of a cash bonus to an expected non-cash restricted stock grant for an executive that will be
amortized as non-cash, share-based compensation expense over the future service period and (ii) a $0.4 million decrease as a result of the
decrease in the fair value of our deferred compensation plan assets. The ratio of our total operating expenses, excluding interest expense, as
a percentage of our quarterly average total assets for the year ended December 31, 2018 was 1.4% on an annualized basis compared to 1.6%
for the year ended December 31, 2017.

Net Investment Income

       Net investment income for the year ended December 31, 2018 was $156.6 million, or a 16% increase, compared to net investment
income of $135.4 million for the corresponding period of 2017. The increase in net investment income was principally attributable to the
increase in total investment income, partially offset by higher operating expenses both as discussed above.

Distributable Net Investment Income

       For the year ended December 31, 2018, distributable net investment income increased 14% to $165.8 million, or $2.76 per share,
compared with $145.4 million, or $2.56 per share, in the corresponding period of 2017. The increase in distributable net investment income
was primarily due to the higher level of total investment income, partially offset by higher operating expenses both as discussed above.
Distributable net investment income on a per share basis for the year ended December 31, 2018 reflects (i) a consistent level of income per
share from the comparable period in 2017 attributable to the net effect of the elevated dividend income activity, offset by the decreases in
interest income associated with the comparable levels of activity from portfolio companies that is considered to be less consistent on a
recurring basis or non-recurring and accelerated prepayment, repricing and other income activity considered non-recurring, as discussed
above,

65

Table of Contents

(ii) an increase of $0.03 per share due to the non-recurring benefit to compensation expense and the decrease in the fair value of the
deferred compensation plan assets, both as discussed above, and (iii) a greater number of average shares outstanding compared to the
corresponding period in 2017 primarily due to shares issued through the ATM Program (as defined in "— Liquidity and Capital
Resources — Capital Resources" below), shares issued pursuant to our equity incentive plans and shares issued pursuant to our dividend
reinvestment plan.

Net Increase in Net Assets Resulting from Operations

       The net increase in net assets resulting from operations during the year ended December 31, 2018 was $168.2 million, or $2.80 per
share, compared with $170.6 million, or $3.01 per share, during the year ended December 31, 2017. This $2.4 million decrease from the
prior year was primarily the result of (i) a $29.5 million decrease in net unrealized appreciation from portfolio investments and SBIC
debentures, including the impact of accounting reversals relating to realized gains/income (losses), and (ii) a $14.8 million decrease in the
net realized gain from investments, with these decreases partially offset by (i) a $21.3 million increase in net investment income as
discussed above, (ii) a $18.3 million decrease in the income tax provision and (iii) a $2.3 million improvement in the net realized loss on
extinguishment of debt. The net realized gain from investments of $1.3 million for the year ended December 31, 2018 was primarily the
result of (i) the net realized gain of $13.7 million resulting from the net effect of gains on the exits of six LMM investments, partially offset
by losses on the exits of four LMM investments and other activity in the LMM portfolio, (ii) the realized gains of $6.1 million due to
activity in our Other Portfolio and (iii) the realized gains of $2.5 million in our Private Loan portfolio, with the effect of these net realized
gains partially offset by the net realized loss of $20.9 million in our Middle Market portfolio, which is primarily the result of (i) the
realized losses of $17.6 million on the restructures of two Middle Market investments and (ii) the realized losses of $4.4 million on the
exits of two Middle Market investments.

       The income tax provision for the year ended December 31, 2018 of $6.2 million principally consisted of a deferred tax provision of
$5.8 million, which is primarily the result of the net activity relating to our portfolio investments held in our Taxable Subsidiaries,
including changes in loss carryforwards, changes in net unrealized appreciation/depreciation and other temporary book-tax differences, and
other current tax expense of $0.4 million.

Distributable net investment income is net investment income as determined in accordance with U.S. GAAP,
excluding the impact of share-based compensation expense which is non-cash in nature. We believe presenting
distributable net investment income and related per share amounts is useful and appropriate supplemental
disclosure of information for analyzing our financial performance since share-based compensation does not require
settlement in cash. However, distributable net investment income is a non-U.S. GAAP measure and should not be
considered as a replacement to net investment income and other earnings measures presented in accordance with
U.S. GAAP. Instead, distributable net investment income should be reviewed only in connection with such
U.S. GAAP measures in analyzing our financial performance. A reconciliation of net investment income in
accordance with U.S. GAAP to distributable net investment income is presented in the table above.

Investment Income

       For the year ended December 31, 2017, total investment income was $205.7 million, a 15% increase over the $178.3 million of total
investment income for the corresponding period of 2016. This comparable period increase was principally attributable to (i) a $23.2 million
increase in interest income primarily related to higher average levels of portfolio debt investments and increased activities involving
existing Investment Portfolio debt investments, (ii) a $2.5 million increase in dividend income from Investment Portfolio equity
investments and (iii) a $1.8 million increase in fee income. The $27.4 million increase in total investment income in the year ended
December 31, 2017 includes (i) an increase of $6.7 million related to higher accelerated prepayment, repricing and other activity for certain
portfolio debt investments when compared to the same period in 2016, (ii) an increase of $2.7 million related to interest income activity
from portfolio companies that is considered to be less consistent on a recurring basis or non-recurring during the period when compared to
the same period in 2016 and (iii) includes $1.7 million related to dividend income activity from portfolio companies that is considered to be
less consistent on a recurring basis or non-recurring which is consistent with the amount from such dividend income activity in the same
period in 2016.

Expenses

       For the year ended December 31, 2017, total expenses increased to $70.4 million from $62.5 million for the corresponding period of
2016. This comparable period increase in operating expenses was principally attributable to (i) a $2.8 million increase in interest expense,
primarily due to (a) a $1.4 million increase on the Credit Facility due to the higher average interest rate during 2017, (b) a $0.9 million
increase due to the issuance of our 4.50% Notes due 2022 in November 2017 and (c) a $0.5 million increase due to the higher average
balance of SBIC debentures outstanding, (ii) a $2.4 million increase in general and administrative expenses, including approximately
$0.6 million related to non-recurring professional fees and other expenses incurred on certain potential new portfolio investment
opportunities which were terminated during the due diligence and legal documentation processes, (iii) a $2.2 million increase in
compensation expense related to increases in the number of personnel, base compensation levels and incentive compensation accruals and
(iv) a $1.7 million increase in share-based compensation expense, with these increases partially offset by a $1.3 million increase in the
expenses allocated to the External Investment Manager, in each case when compared to the same period in the prior year. For the years
ended December 31, 2017 and 2016, the ratio of our total operating expenses, excluding interest expense and the non-recurring professional
fees and other expenses discussed above as a percentage of our quarterly average total assets was 1.5%. Including the effect of the non-
recurring expenses, the ratio for the year ended December 31, 2017 was 1.6%.

Net Investment Income

       Net investment income for the year ended December 31, 2017 was $135.4 million, or a 17% increase, compared to net investment
income of $115.8 million for the corresponding period of 2016. The increase in net investment income was principally attributable to the
increase in total investment income, partially offset by higher operating expenses both as discussed above.

Distributable Net Investment Income

       For the year ended December 31, 2017, distributable net investment income increased 17% to $145.4 million, or $2.56 per share,
compared with $124.1 million, or $2.39 per share in 2016. The increase in distributable net investment income was primarily due to the
higher level of total investment income, partially offset by higher operating expenses both as discussed above. Distributable net investment
income on a per share basis for the year ended December 31, 2017 reflects an (i) increase of approximately $0.16 per share from the
comparable period in 2016 attributable to the net increase in the comparable levels of accelerated prepayment, repricing and other, unusual
activity for certain Investment Portfolio debt investments and (ii) a greater number of average shares outstanding compared to the
corresponding period in 2016 primarily due to shares issued through the ATM Program (as defined in "— Liquidity and Capital
Resources — Capital Resources" below), shares issued pursuant to our equity incentive plans and shares issued pursuant to our dividend
reinvestment plan.

Net Increase in Net Assets Resulting from Operations

       The net increase in net assets resulting from operations during the year ended December 31, 2017 was $170.6 million, or $3.01 per
share, compared with $138.9 million, or $2.67 per share, during the year ended December 31, 2016. This $31.7 million increase from the
prior year was primarily the result of (i) a $56.3 million improvement in net unrealized appreciation (depreciation) from portfolio
investments and SBIC debentures, including the impact of accounting reversals relating to realized gains/income (losses), from net
unrealized depreciation of $7.5 million for the year ended December 31, 2016 to net unrealized appreciation of $48.8 million for the year
ended December 31, 2017, which includes the impact of approximately $15.0 million of unrealized appreciation in the LMM equity
portfolio related to the enactment of the Tax Cuts and Jobs Act (see further discussion above in "— Critical Accounting Policies — Income
Taxes") and (ii) a $19.6 million increase in net investment income as discussed above, with these increases partially offset by (i) a
$25.7 million change in the income tax benefit (provision) from an income tax benefit of $1.2 million for the year ended December 31,
2016 to an income tax provision of $24.5 million for the year ended December 31, 2017, (ii) a $13.2 million decrease in the net realized
gain from investments to a total net realized gain from investments of $16.2 million for the year ended December 31, 2017 and (iii) a
$5.2 million realized loss on the repayment of SBIC debentures outstanding at MSC II which had previously been accounted for on the fair
value method of accounting. The net realized gain from investments of $16.2 million for the year ended December 31, 2017 was primarily
the result of (i) the net realized gain of $11.8 million resulting from gains on the exits of five LMM investments and losses on the exits of
four LMM investments, (ii) realized gains of $9.3 million due to activity in our Other Portfolio, (iii) net realized gains of $3.0 million in our
Private Loan portfolio resulting from gains on the exits of two Private Loan investments and a loss on the restructure of a Private Loan
investment, (iv) realized gains of $2.1 million related to other activity in the LMM portfolio and (v) the net realized loss of $9.8 million in
our Middle Market portfolio, which is primarily the result of (a) realized losses of $7.9 million on the exits of two Middle Market
investments and (b) the realized loss of $3.5 million on the restructure of a Middle Market investment, with these changes partially offset
by $1.5 million of net realized gains on other activity in our Middle Market portfolio. The realized loss of $5.2 million on the repayment of
SBIC debentures is related to the previously recognized bargain purchase gain resulting from recording the MSC II debentures at fair value
on the date of the acquisition of the majority of the equity interests of MSC II in 2010. The effect of the realized loss is offset by the
reversal of all previously recognized unrealized depreciation on these SBIC debentures due to fair value adjustments since the date of the
acquisition.

adjustments since such date and $0.2 million of current period unrealized appreciation on the remaining SBIC
debentures.

       The income tax provision for the year ended December 31, 2017 of $24.5 million principally consisted of a deferred tax provision of
$19.3 million, which is primarily the result of the net activity relating to our portfolio investments held in our Taxable Subsidiaries,
including changes in loss carryforwards, changes in net unrealized appreciation/depreciation and other temporary book-tax differences, and
other current tax expense of $5.2 million related to (i) a $1.9 million accrual for excise tax on our estimated undistributed taxable income
and (ii) current tax expense of $3.3 million related to accruals for U.S. federal and state income taxes.

Liquidity and Capital Resources

Cash Flows

       For the year ended December 31, 2018, we experienced a net increase in cash and cash equivalents in the amount of approximately
$2.7 million, which is the net result of approximately $109.1 million of cash used in our operating activities and approximately
$111.7 million of cash provided by our financing activities.

       During the year ended December 31, 2018, $109.1 million of cash was used in our operating activities, which resulted primarily from
(i) cash flows we generated from the operating profits earned through our operating activities totaling $149.8 million, which is our
$165.8 million of distributable net investment income, excluding the non-cash effects of the accretion of unearned income of $14.7 million,
payment-in-kind interest income of $2.3 million, cumulative dividends of $2.3 million and the amortization expense for deferred financing
costs of $3.3 million, and (ii) cash uses totaling $963.4 million, which principally consisted of $962.5 million for the funding of new
portfolio company investments and settlement of accruals

proceeds totaling $704.6 million from $703.2 million in cash proceeds from the sales and repayments of debt investments and sales of and
return on capital of equity investments and $1.4 million related to decreases in other assets.

       During the year ended December 31, 2018, $111.7 million in cash was provided by financing activities, which principally consisted of
(i) $237.0 million in net cash proceeds from the Credit Facility (ii) $78.4 million in net cash proceeds from the ATM Program (described
below), and (iii) $54.0 million in cash proceeds from issuance of SBIC debentures, partially offset by (i) $156.0 million in cash dividends
paid to stockholders, (ii) $90.7 million in redemption of 6.125% Notes, (iii) $4.0 million in repayment of SBIC debentures,
(iv) $4.1 million for purchases of vested restricted stock from employees to satisfy their tax withholding requirements upon the vesting of
such restricted stock and (v) $2.9 million for payment of deferred debt issuance costs, SBIC debenture fees and other costs.

       For the year ended December 31, 2017, we experienced a net increase in cash and cash equivalents in the amount of approximately
$27.0 million, which is the result of approximately $72.9 million of cash provided by our operating activities and approximately
$45.9 million of cash used in financing activities.

       During the year ended December 31, 2017, $72.9 million of cash was provided by our operating activities, which resulted primarily
from (i) cash flows we generated from the operating profits earned through our operating activities totaling $123.1 million, which is our
$145.4 million of distributable net investment income, excluding the non-cash effects of the accretion of unearned income of $17.0 million,
payment-in-kind interest income of $4.9 million, cumulative dividends of $3.2 million and the amortization expense for deferred financing

requirements upon the vesting of such restricted stock and (iv) $5.9 million for payment of deferred debt issuance costs, SBIC debenture
fees and other costs.

Capital Resources

       As of December 31, 2018, we had $54.2 million in cash and cash equivalents and $404.0 million of unused capacity under the Credit
Facility, which we maintain to support our investment and operating activities. As of December 31, 2018, our net asset value totaled
$1,476.0 million, or $24.09 per share.

       The Credit Facility, which provides additional liquidity to support our investment and operational activities, was amended and restated
during 2018 to provide for an increase in total commitments from $585.0 million to $705.0 million and to increase the diversified group of
lenders to eighteen, eliminate interest rate adjustments previously subject to our maintenance of an investment grade rating and extend the
final maturity by two years to September 2023. The amended Credit Facility also contains an upsized accordion feature which allows us to
increase the total commitments under the facility to up to $800.0 million from new and existing lenders on the same terms and conditions as
the existing commitments.

       Borrowings under the Credit Facility bear interest, subject to our election, on a per annum basis at a rate equal to the applicable LIBOR
rate (2.5% as of December 31, 2018) plus (i) 1.875% (or the applicable base

71

Table of Contents

rate (Prime Rate of 5.5% as of December 31, 2018) plus 0.875%) as long as we meet certain agreed upon excess collateral and maximum
leverage requirements or (ii) 2.0% (or the applicable base rate plus 1.0%) otherwise. We pay unused commitment fees of 0.25% per annum
on the unused lender commitments under the Credit Facility. The Credit Facility is secured by a first lien on the assets of MSCC and its
subsidiaries, excluding the equity ownership or assets of the Funds and the External Investment Manager. The Credit Facility contains
certain affirmative and negative covenants, including but not limited to: (i) maintaining a minimum availability of at least 10% of the
borrowing base, (ii) maintaining an interest coverage ratio of at least 2.0 to 1.0, (iii) maintaining an asset coverage ratio (tangible net worth
to Credit Facility borrowings) of at least 1.5 to 1.0 and (iv) maintaining a minimum tangible net worth. The Credit Facility is provided on a
revolving basis through its final maturity date in September 2023, and contains two, one-year extension options which could extend the
final maturity by up to two years, subject to certain conditions, including lender approval. As of December 31, 2018, we had $301.0 million
in borrowings outstanding under the Credit Facility, the interest rate on the Credit Facility was 4.2% and we were in compliance with all
financial covenants of the Credit Facility.

       Through the Funds, we have the ability to issue SBIC debentures guaranteed by the SBA at favorable interest rates and favorable terms
and conditions. Under existing SBA regulations, SBA approved SBICs under common control have the ability to issue debentures
guaranteed by the SBA up to a regulatory maximum amount of $350.0 million. Through the Funds, we have an effective maximum amount
of $346.0 million following the prepayment of $4.0 million of existing SBIC debentures as discussed below. During the year ended
December 31, 2018, we issued $54.0 million of SBIC debentures and opportunistically prepaid $4.0 million of our existing SBIC
debentures as part of an effort to manage the maturity dates of our oldest SBIC debentures. Debentures guaranteed by the SBA have fixed
interest rates that equal prevailing 10-year Treasury Note rates plus a market spread and have a maturity of ten years with interest payable
semiannually. The principal amount of the debentures is not required to be paid before maturity, but may be pre-paid at any time with no
prepayment penalty. We expect to issue new SBIC debentures under the SBIC program in the future in an amount up to the regulatory
maximum amount for affiliated SBIC funds. As of December 31, 2018, through our three wholly owned SBICs, we had $345.8 million of
outstanding SBIC debentures guaranteed by the SBA, which bear a weighted-average annual fixed interest rate of approximately 3.7%,
paid semiannually, and mature ten years from issuance. The first maturity related to our SBIC debentures occurs in 2019, and the weighted-
average remaining duration is approximately 5.6 years as of December 31, 2018.

       In April 2013, we issued $92.0 million, including the underwriters' full exercise of their over-allotment option, in aggregate principal
amount of the 6.125% Notes (the "6.125% Notes"). The 6.125% Notes bore interest at a rate of 6.125% per year payable quarterly on
January 1, April 1, July 1 and October 1 of each year. The total net proceeds to us from the 6.125% Notes, after underwriting discounts and
estimated offering expenses payable, were approximately $89.0 million. On April 2, 2018, we redeemed the entire principal amount of the
issued and outstanding 6.125% Notes effective April 1, 2018 (the "Redemption Date"). The 6.125% Notes were redeemed at par value, plus
the accrued and unpaid interest thereon from January 1, 2018, through, but excluding, the Redemption Date. As part of the redemption, we
recognized a realized loss on extinguishment of debt of $1.5 million in the second quarter of 2018 related to the write-off of the related
unamortized deferred financing costs.

       In November 2014, we issued $175.0 million in aggregate principal amount of 4.50% unsecured notes due 2019 (the "4.50% Notes due
2019") at an issue price of 99.53%. The 4.50% Notes due 2019 are unsecured obligations and rank pari passu with our current and future
unsecured indebtedness; senior to any of our future indebtedness that expressly provides it is subordinated to the 4.50% Notes due 2019;
effectively subordinated to all of our existing and future secured indebtedness, to the extent of the value of the assets securing such
indebtedness, including borrowings under our Credit Facility; and structurally subordinated to all existing and future indebtedness and other
obligations of any of our subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50% Notes due 2019 mature on
December 1, 2019, and may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions. The

72

Table of Contents

4.50% Notes due 2019 bear interest at a rate of 4.50% per year payable semiannually on June 1 and December 1 of each year. We may
from time to time repurchase 4.50% Notes due 2019 in accordance with the 1940 Act and the rules promulgated thereunder. As of
December 31, 2018, the outstanding balance of the 4.50% Notes due 2019 was $175.0 million.

       The indenture governing the 4.50% Notes due 2019 (the "4.50% Notes due 2019 Indenture") contains certain covenants, including
covenants requiring our compliance with (regardless of whether we are subject to) the asset coverage requirements set forth in Section 18(a)
(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring us to provide financial information to the holders of
the 4.50% Notes due 2019 and the Trustee if we cease to be subject to the reporting requirements of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"). These covenants are subject to limitations and exceptions that are described in the 4.50% Notes due
2019 Indenture.

       In November 2017, we issued $185.0 million in aggregate principal amount of 4.50% unsecured notes due 2022 (the "4.50% Notes due
2022") at an issue price of 99.16%. The 4.50% Notes due 2022 are unsecured obligations and rank pari passu with our current and future
unsecured indebtedness; senior to any of our future indebtedness that expressly provides it is subordinated to the 4.50% Notes due 2022;
effectively subordinated to all of our existing and future secured indebtedness, to the extent of the value of the assets securing such
indebtedness, including borrowings under our Credit Facility; and structurally subordinated to all existing and future indebtedness and other
obligations of any of our subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50% Notes due 2022 mature on
December 1, 2022, and may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions. The 4.50%
Notes due 2022 bear interest at a rate of 4.50% per year payable semiannually on June 1 and December 1 of each year. We may from time
to time repurchase 4.50% Notes due 2022 in accordance with the 1940 Act and the rules promulgated thereunder. As of December 31, 2018,
the outstanding balance of the 4.50% Notes due 2022 was $185.0 million.

       The indenture governing the 4.50% Notes due 2022 (the "4.50% Notes due 2022 Indenture") contains certain covenants, including
covenants requiring our compliance with (regardless of whether we are subject to) the asset coverage requirements set forth in Section 18(a)
(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring us to provide financial information to the holders of
the 4.50% Notes due 2022 and the Trustee if we cease to be subject to the reporting requirements of the Exchange Act. These covenants are
subject to limitations and exceptions that are described in the 4.50% Notes due 2022 Indenture.

       We maintain a program with certain selling agents through which we can sell shares of our common stock by means of at-the-market
offerings from time to time (the "ATM Program").

       During the year ended December 31, 2016, we sold 3,324,646 shares of our common stock at a weighted-average price of $34.17 per
share and raised $113.6 million of gross proceeds under the ATM Program. Net proceeds were $112.0 million after commissions to the
selling agents on shares sold and offering costs.

       During the year ended December 31, 2017, we sold 3,944,972 shares of our common stock at a weighted-average price of $38.72 per
share and raised $152.8 million of gross proceeds under the ATM Program. Net proceeds were $150.9 million after commissions to the
selling agents on shares sold and offering costs.

       During the year ended December 31, 2018, we sold 2,060,019 shares of our common stock at a weighted-average price of $38.48 per
share and raised $79.3 million of gross proceeds under the ATM Program. Net proceeds were $78.0 million after commissions to the
selling agents on shares sold and offering costs. As of December 31, 2018, 2,994,469 shares remained available for sale under the ATM
Program.

       We anticipate that we will continue to fund our investment activities through existing cash and cash equivalents, cash flows generated
through our ongoing operating activities, utilization of available borrowings under our Credit Facility, and a combination of future
issuances of debt and equity capital. Our primary uses

73

Table of Contents

of funds will be investments in portfolio companies, operating expenses and cash distributions to holders of our common stock.

       We periodically invest excess cash balances into marketable securities and idle funds investments. The primary investment objective of
marketable securities and idle funds investments is to generate incremental cash returns on excess cash balances prior to utilizing those
funds for investment in our LMM, Middle Market and Private Loan portfolio investments. Marketable securities and idle funds investments
generally consist of debt investments, independently rated debt investments, certificates of deposit with financial institutions, diversified
bond funds and publicly traded debt and equity investments.

       If our common stock trades below our net asset value per share, we will generally not be able to issue additional common stock at the
market price unless our stockholders approve such a sale and our Board of Directors makes certain determinations. We did not seek
stockholder authorization to sell shares of our common stock below the then current net asset value per share of our common stock at our
2018 annual meeting of stockholders because our common stock price per share had been trading significantly above the net asset value per
share of our common stock since 2011. We would therefore need future approval from our stockholders to issue shares below the then
current net asset value per share.

       In order to satisfy the Code requirements applicable to a RIC, we intend to distribute to our stockholders, after consideration and
application of our ability under the Code to carry forward certain excess undistributed taxable income from one tax year into the next tax
year, substantially all of our taxable income. In addition, as a BDC, we generally are required to meet a coverage ratio of total assets to total
senior securities, which include borrowings and any preferred stock we may issue in the future, of at least 200% (or 150% if certain
requirements are met). This requirement limits the amount that we may borrow. In January 2008, we received an exemptive order from the
SEC to exclude SBA-guaranteed debt securities issued by MSMF and any other wholly owned subsidiaries of ours which operate as SBICs
from the asset coverage requirements of the 1940 Act as applicable to us, which, in turn, enables us to fund more investments with debt
capital.

       Although we have been able to secure access to additional liquidity, including through the Credit Facility, public debt issuances,
leverage available through the SBIC program and equity offerings, there is no assurance that debt or equity capital will be available to us in
the future on favorable terms, or at all.

Recently Issued or Adopted Accounting Standards

       In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606).
ASU 2014-09 supersedes the revenue recognition requirements under ASC 605, Revenue Recognition, and most industry-specific guidance
throughout the Industry Topics of the ASC. The core principle of the guidance is that an entity should recognize revenue to depict the
transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in
exchange for those goods or services. Under the guidance, an entity is required to perform the following five steps: (1) identify the
contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the
transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance
obligation. The guidance will significantly enhance comparability of revenue recognition practices across entities, industries, jurisdictions
and capital markets. Additionally, the guidance requires improved disclosures as to the nature, amount, timing and uncertainty of revenue
that is recognized. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus
Agent Considerations (Reporting Revenue Gross versus Net), which clarified the implementation guidance on principal versus agent
considerations. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying
Performance Obligations and Licensing, which clarified the implementation guidance regarding performance obligations and licensing
arrangements. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606) — Narrow-Scope
Improvements and Practical Expedients, which clarified guidance on assessing collectability, presenting sales tax, measuring noncash
consideration, and certain transition matters. In December 2016, the FASB issued

74

Table of Contents

ASU No. 2016-20, Revenue from Contracts with Customers (Topic 606) — Technical Corrections and Improvements, which provided
disclosure relief, and clarified the scope and application of the new revenue standard and related cost guidance. The guidance is effective
for the annual reporting period beginning after December 15, 2017, including interim periods within that reporting period. Substantially all
of our income is not within the scope of ASU 2014-09. For those income items that are within the scope (primarily fee income), we have
similar performance obligations as compared with deliverables and separate units of account previously identified. As a result, our timing of
income recognition remains the same and the adoption of the standard was not material.

       In February 2016, the FASB issued ASU 2016-02, Leases, which requires lessees to recognize on the balance sheet a right-of-use
asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than
12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of
cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of
optional practical expedients that entities may elect to apply. The guidance is effective for annual periods beginning after December 15,
2018, and interim periods therein. Early application is permitted. While we continue to assess the effect of adoption, we currently believe
the most significant change relates to the recognition of a new right-of-use asset and lease liability on our consolidated balance sheet for
our office space operating lease. We currently have one operating lease for office space and do not expect a significant change in our
leasing activity between now and adoption. See further discussion of our operating lease obligation in "Note K — Commitments and
Contingences" in the notes to the consolidated financial statements.

       In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which is intended to reduce the existing
diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The
guidance is effective for annual periods beginning after December 15, 2017, and interim periods therein. We have adopted ASU 2016-15.
The impact of the adoption of this accounting standard on our consolidated financial statements was not material.

       In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which is intended to improve fair value and
defined benefit disclosure requirements by removing disclosures that are not cost-beneficial, clarifying disclosures' specific requirements,
and adding relevant disclosure requirements. The amendments take effect for all organizations for fiscal years, and interim periods within
those fiscal years, beginning after December 15, 2019. Early adoption is permitted. We have elected to early adopt ASU 2018-13 in the
current annual period. No significant changes were made to our fair value disclosures in the notes to the consolidated financial statements
in order to comply with ASU 2018-13.

       In August 2018, the SEC adopted rules (the "SEC Release") amending certain disclosure requirements intended to eliminate redundant,
duplicative, overlapping, outdated, or superseded, in light of other SEC disclosure requirements, US GAAP requirements, or changes in the
information environment. In part, the SEC Release requires an investment company to present distributable earnings in total on the
consolidated balance sheet and consolidated statement of changes in net assets, rather than showing the three components of distributable
earnings as previously shown. We adopted this part of the SEC Release in the current annual period and the changes in presentation have
been retrospectively applied to the consolidated balance sheet as of December 31, 2017 and to the consolidated statements of changes in
net assets for the years ended December 31, 2017 and 2016. The impact of the adoption of these rules on our consolidated financial
statements was not material. Additionally, the SEC Release requires disclosure of changes in net assets within a registrant's Form 10-Q
filing on a quarter-to-date and year-to-date basis for both the current year and prior year comparative periods. We expect to adopt the new
requirement to present changes in shareholders' equity in interim financial statements within Form 10-Q filings starting with the quarter
ending March 31, 2019. The compliance date for the SEC Release was for all filings, as applicable, on or after November 5, 2018. The
adoption of these additional rules will not have a material impact on the consolidated financial statements.

75

Table of Contents

       From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by us as
of the specified effective date. We believe that the impact of recently issued standards and any that are not yet effective will not have a
material impact on our consolidated financial statements upon adoption.

Inflation

       Inflation has not had a significant effect on our results of operations in any of the reporting periods presented herein. However, our
portfolio companies have experienced, and may in the future experience, the impacts of inflation on their operating results, including
periodic escalations in their costs for labor, raw materials and third-party services and required energy consumption.

Off-Balance Sheet Arrangements

       We may be a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of
our portfolio companies. These instruments include commitments to extend credit and fund equity capital and involve, to varying degrees,
elements of liquidity and credit risk in excess of the amount recognized in the balance sheet. At December 31, 2018, we had a total of
$136.9 million in outstanding commitments comprised of (i) 33 investments with commitments to fund revolving loans that had not been
fully drawn or term loans with additional commitments not yet funded and (ii) 11 investments with equity capital commitments that had not
been fully called.

Contractual Obligations

       As of December 31, 2018, the future fixed commitments for cash payments in connection with our SBIC debentures, the 4.50% Notes
due 2019, the 4.50% Notes due 2022 and rent obligations under our office lease for each of the next five years and thereafter are as follows:

Operating Lease Obligation means a rent payment obligation under a lease classified as an operating lease and
disclosed pursuant to FASB ASC 840, as may be modified or supplemented.

       As of December 31, 2018, we had $301.0 million in borrowings outstanding under our Credit Facility, and the Credit Facility is
currently scheduled to mature in September 2023. The Credit Facility contains two, one-year extension options which could extend the
maturity to September 2025, subject to lender approval. See further discussion of the Credit Facility terms in "— Liquidity and Capital
Resources — Capital Resources."

Related Party Transactions

       As discussed further above, the External Investment Manager is treated as a wholly owned portfolio company of MSCC and is
included as part of our Investment Portfolio. At December 31, 2018, we had a receivable of approximately $2.9 million due from the
External Investment Manager which included approximately $1.8 million primarily related to operating expenses incurred by us as required
to support the

External Investment Manager's business and amounts due from the External Investment Manager to Main Street under a tax sharing
agreement (see further discussion above in "— Critical Accounting Policies — Income Taxes") and approximately $1.2 million of
dividends declared but not paid by the External Investment Manager.

       In November 2015, our Board of Directors approved and adopted the Main Street Capital Corporation Deferred Compensation Plan
(the "2015 Deferred Compensation Plan"). The 2015 Deferred Compensation Plan became effective on January 1, 2016 and replaced the
Deferred Compensation Plan for Non-Employee Directors previously adopted by the Board of Directors in June 2013 (the "2013 Deferred
Compensation Plan"). Under the 2015 Deferred Compensation Plan, non-employee directors and certain key employees may defer receipt
of some or all of their cash compensation and directors' fees, subject to certain limitations. Individuals participating in the 2015 Deferred
Compensation Plan receive distributions of their respective balances based on predetermined payout schedules or other events as defined
by the plan and are also able to direct investments made on their behalf among investment alternatives permitted from time to time under
the plan, including phantom Main Street stock units. As of December 31, 2018, $6.1 million of compensation and directors' fees had been
deferred under the 2015 Deferred Compensation Plan (including amounts previously deferred under the 2013 Deferred Compensation
Plan). Of this amount, $3.3 million was deferred into phantom Main Street stock units, representing 97,344 shares of our common stock.
Including phantom stock units issued through dividend reinvestment and net of any shares distributed, the phantom stock units outstanding
as of December 31, 2018 represented 119,639 shares of our common stock. Any amounts deferred under the plan represented by phantom
Main Street stock units will not be issued or included as outstanding on the consolidated statements of changes in net assets until such
shares are actually distributed to the participant in accordance with the plan, but are included in operating expenses and weighted-average
shares outstanding in our consolidated statements of operations as earned.

Recent Developments

       In January 2019, we led a new portfolio investment to facilitate the minority recapitalization of Centre Technologies, Inc. ("Centre"), a
premier provider of IT hardware, software and service solutions. We, along with our co-investors, partnered with Centre's founder and
Chief Executive Officer and management team to facilitate the transaction, with us funding $18.1 million in a combination of first-lien,
senior secured term debt and a direct equity investment. Headquartered in Houston, Texas, and founded in 2006, Centre has established
itself as a mission critical IT solutions provider offering a full suite of solutions including managed and hosted services, value-added
sourcing and integration, and project services.

       In January 2019, we led a new portfolio investment to facilitate the management buyout of CompareNetworks Inc.
("CompareNetworks"), a leading provider of media, marketing and technology solutions that drive revenue for life science and healthcare
product manufacturers. We, along with our co-investors, partnered with CompareNetworks' founders and management team to facilitate the
transaction, with us funding $10.7 million in a combination of first-lien, senior secured term debt and a direct equity investment.
Headquartered in South San Francisco, California, and founded in 2000, CompareNetworks provides life scientists, researchers, lab-based
professionals, pharmaceutical professionals and healthcare professionals with digital tools and information resources to research, identify
and determine which products and technologies to use.

       In January 2019, we fully exited our equity investment in Boss Industries, LLC ("Boss"). Boss markets, designs and manufacturers
vehicle-mounted, and portable air compressor and generator systems utilized in municipal and utility services, energy product and industrial
services. We realized a gain of approximately $4.0 million on the exit of our equity investment in Boss.

       During February 2019, we declared regular monthly dividends of $0.200 per share for each month of April, May and June 2019. These
regular monthly dividends equal a total of $0.600 per share for the second quarter of 2019 and represent a 5.3% increase from the dividends
declared for the second quarter of 2018.

77

Table of Contents

Including the dividends declared for the second quarter of 2019, we will have paid $25.420 per share in cumulative dividends since our
October 2007 initial public offering.

Item 7A.    Quantitative and Qualitative Disclosures about Market Risk 

       We are subject to financial market risks, including changes in interest rates. Changes in interest rates may affect both our cost of
funding and our interest income from portfolio investments. Our risk management systems and procedures are designed to identify and
analyze our risk, to set appropriate policies and limits and to continually monitor these risks. Our investment income will be affected by
changes in various interest rates, including LIBOR and prime rates, to the extent that any debt investments include floating interest rates.
The majority of our debt investments are made with either fixed interest rates or floating-rates that are subject to contractual minimum
interest rates for the term of the investment. As of December 31, 2018, approximately 72% of our debt investment portfolio (at cost) bore
interest at floating rates, 90% of which were subject to contractual minimum interest rates. Our interest expense will be affected by changes
in the published LIBOR rate in connection with our Credit Facility; however, the interest rates on our outstanding SBIC debentures, 4.50%
Notes due 2019 and 4.50% Notes due 2022, which comprise the majority of our outstanding debt, are fixed for the life of such debt. As of
December 31, 2018, we had not entered into any interest rate hedging arrangements. The following table shows the approximate annualized
increase or decrease in the components of net investment income due to hypothetical base rate changes in interest rates, assuming no
changes in our investments and borrowings as of December 31, 2018.

Board of Directors and Stockholders'
Main Street Capital Corporation

Opinion on the financial statements

Report of Independent Registered Public Accounting Firm 

       We have audited the accompanying consolidated balance sheets of Main Street Capital Corporation (a Maryland corporation) and
subsidiaries (the "Company"), including the consolidated schedule of investments, as of December 31, 2018 and 2017, the related
consolidated statements of operations, changes in net assets, and cash flows for each of the three years in the period ended December 31,
2018, and the related notes, schedules and financial highlights (collectively referred to as the "financial statements"). In our opinion, the
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and
the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, and the financial
highlights for each of the five years in the period ended December 31, 2018, in conformity with accounting principles generally accepted in
the United States of America.

       We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
("PCAOB"), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in the 2013
Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"),
and our report dated March 1, 2019 expressed an unqualified opinion.

Basis for opinion

       These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the
Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

       We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our
audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud,
and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included
verification by confirmation of securities as of December 31, 2018 and 2017, by correspondence with the portfolio companies and
custodians, or by other appropriate auditing procedures where replies were not received. We believe that our audits provide a reasonable
basis for our opinion.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Stockholders'
Main Street Capital Corporation

Opinion on internal control over financial reporting

       We have audited the internal control over financial reporting of Main Street Capital Corporation (a Maryland corporation) and
subsidiaries (the "Company") as of December 31, 2018, based on criteria established in the 2013 Internal Control — Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in
all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in the 2013
Internal Control — Integrated Framework issued by COSO.

       We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States)
("PCAOB"), the consolidated financial statements of the Company, as of and for the year ended December 31, 2018 and our report dated
March 1, 2019, expressed an unqualified opinion on those financial statements.

Basis for opinion

       The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of
the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over
Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our
audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and
the PCAOB.

       We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our
audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and limitations of internal control over financial reporting

       A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting
principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance
of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

       Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

All investments are Lower Middle Market portfolio investments, unless otherwise noted. See Note B for a description of Lower Middle Market
portfolio investments. All of the Company's investments, unless otherwise noted, are encumbered either as security for the Company's Credit
Agreement or in support of the SBA-guaranteed debentures issued by the Funds. 

Debt investments are income producing, unless otherwise noted. Equity and warrants are non-income producing, unless otherwise noted. 

See Note C for a summary of geographic location of portfolio companies. 

Principal is net of repayments. Cost is net of repayments and accumulated unearned income. 

Control investments are defined by the Investment Company Act of 1940, as amended ("1940 Act") as investments in which more than 25% of the
voting securities are owned or where the ability to nominate greater than 50% of the board representation is maintained. 

Affiliate investments are defined by the 1940 Act as investments in which between 5% and 25% of the voting securities are owned and the
investments are not classified as Control investments. 

Non-Control/Non-Affiliate investments are defined by the 1940 Act as investments that are neither Control investments nor Affiliate investments.

Income producing through dividends or distributions. 

Index based floating interest rate is subject to contractual minimum interest rate. A majority of the variable rate loans in the Company's investment
portfolio bear interest at a rate that may be determined by reference to either LIBOR or an alternate Base Rate (commonly based on the Federal
Funds Rate or the Prime Rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to
have multiple interest reset periods for each loan. For each such loan, the Company has provided the weighted average annual stated interest rate in

Other Portfolio investment. See Note B for a description of Other Portfolio investments. 

Investment is not a qualifying asset as defined under Section 55(a) of the 1940 Act. Qualifying assets must represent at least 70% of total assets at
the time of acquisition of any additional non-qualifying assets. 

Non-accrual and non-income producing investment. 

Portfolio company is in a bankruptcy process and, as such, the maturity date of our debt investments in this portfolio company will not be finally
determined until such process is complete. As noted in footnote (14), our debt investments in this portfolio company are on non-accrual status. 

External Investment Manager. Investment is not encumbered as security for the Company's Credit Agreement or in support of the SBA-guaranteed
debentures issued by the Funds. 

Maturity date is under on-going negotiations with the portfolio company and other lenders, if applicable. 

Investment fair value was determined using significant unobservable inputs, unless otherwise noted. See Note C for further discussion.

In connection with the Company's debt investment in Staples Canada ULC to help mitigate any potential adverse change in foreign exchange rates
during the term of the Company's investment, the Company has a forward foreign currency contract with Cadence Bank to lend $20.4 million
Canadian Dollars and receive $15.7 million U.S. Dollars with a settlement date of September 12, 2019. The unrealized appreciation on the forward
foreign currency contract is $0.6 million as of December 31, 2018. 

The Company has entered into an intercreditor agreement that entitles the Company to the "last out" tranche of the first lien secured loans,
whereby the "first out" tranche will receive priority as to the "last out" tranche with respect to payments of principal, interest, and any other
amounts due thereunder. Therefore, the Company receives a higher interest rate than the contractual stated interest rate of LIBOR plus 6.00%
(Floor 1.00%) per the Credit Agreement and the Consolidated Schedule of Investments above reflects such higher rate.

Investment date represents the date of initial investment in the portfolio company. 

Investment has an unfunded commitment as of December 31, 2018 (see Note K). The fair value of the investment includes the impact of the fair

All investments are Lower Middle Market portfolio investments, unless otherwise noted. See Note B for a description of Lower Middle Market
portfolio investments. All of the Company's investments, unless otherwise noted, are encumbered either as security for the Company's Credit
Agreement or in support of the SBA-guaranteed debentures issued by the Funds. 

Debt investments are income producing, unless otherwise noted. Equity and warrants are non-income producing, unless otherwise noted. 

See Note C for a summary of geographic location of portfolio companies. 

Principal is net of repayments. Cost is net of repayments and accumulated unearned income. 

Control investments are defined by the Investment Company Act of 1940, as amended ("1940 Act") as investments in which more than 25% of the
voting securities are owned or where the ability to nominate greater than 50% of the board representation is maintained. 

Affiliate investments are defined by the 1940 Act as investments in which between 5% and 25% of the voting securities are owned and the
investments are not classified as Control investments. 

Non-Control/Non-Affiliate investments are defined by the 1940 Act as investments that are neither Control investments nor Affiliate investments.

Income producing through dividends or distributions. 

Index based floating interest rate is subject to contractual minimum interest rate. A majority of the variable rate loans in the Company's investment
portfolio bear interest at a rate that may be determined by reference to either LIBOR or an alternate Base Rate (commonly based on the Federal
Funds Rate or the Prime Rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to
have multiple interest reset periods for each loan. For each such loan, the Company has provided the weighted average annual stated interest rate in
effect at December 31, 2017. As noted in this schedule, 67% of the loans (based on the par amount) contain LIBOR floors which range between
0.50% and 2.25%, with a weighted-average LIBOR floor of approximately 1.02%.

Middle Market portfolio investment. See Note B for a description of Middle Market portfolio investments. 

Other Portfolio investment. See Note B for a description of Other Portfolio investments. 

Investment is not a qualifying asset as defined under Section 55(a) of the 1940 Act. Qualifying assets must represent at least 70% of total assets at
the time of acquisition of any additional non-qualifying assets. 

Non-accrual and non-income producing investment. 

Portfolio company is in a bankruptcy process and, as such, the maturity date of our debt investments in this portfolio company will not be finally
determined until such process is complete. As noted in footnote (14), our debt investments in this portfolio company are on non-accrual status. 

External Investment Manager. Investment is not encumbered as security for the Company's Credit Agreement or in support of the SBA-guaranteed
debentures issued by the Funds. 

Maturity date is under on-going negotiations with the portfolio company and other lenders, if applicable. 

Investment fair value was determined using significant unobservable inputs, unless otherwise noted. See Note C for further discussion. 

PIK interest income and cumulative dividend income represent income not paid currently in cash. 

All portfolio company headquarters are based in the United States, unless otherwise noted. 

Portfolio company headquarters are located outside of the United States. 

In connection with the Company's debt investment in Staples Canada ULC to help mitigate any potential adverse change in foreign exchange rates
during the term of the Company's investment, the Company entered into a forward foreign currency contract with Cadence Bank to lend
$24.2 million Canadian Dollars and receive $20.0 million U.S. Dollars with a settlement date of September 12, 2018. The unrealized appreciation on
the forward foreign currency contract is $0.7 million as of December 31, 2017. This unrealized appreciation is offset by the foreign currency
translation depreciation on the investment. 

The Company has entered into an intercreditor agreement that entitles the Company to the "last out" tranche of the first lien secured loans,
whereby the "first out" tranche will receive priority as to the "last out" tranche with respect to payments of principal, interest, and any other
amounts due thereunder. Therefore, the Company receives a higher interest rate than the contractual stated interest rate of LIBOR plus 7.50%
(Floor 1.00%) per the Credit Agreement and the Consolidated Schedule of Investments above reflects such higher rate.

As part of the credit agreement with the portfolio company, the Company is entitled to the "last out" tranche of the first lien secured loans, whereby
the "first out" tranche receives priority over the "last out" tranche with respect to payments of principal, interest, and any other amounts due
thereunder. The rate the Company receives per the Credit Agreement is the same as the rate reflected in the Consolidated Schedule of Investments
above. 

The Company has entered into an intercreditor agreement that entitles the Company to the "first out" tranche of the first lien secured loans,
whereby the "first out" tranche will receive priority as to the "last out" tranche with respect to payments of principal, interest, and any other
amounts due thereunder. Therefore, the Company receives a lower interest rate than the contractual stated interest rate of LIBOR plus 6.64%
(Floor 1.00%) per the Credit Agreement and the Consolidated Schedule of Investments above reflects such lower rate. 

All of the Company's portfolio investments are generally subject to restrictions on resale as "restricted securities." 

Investment date represents the date of initial investment in the portfolio company.

investments of MSCC and its consolidated subsidiaries are typically made to support management buyouts, recapitalizations, growth
financings, refinancings and acquisitions of companies that operate in a variety of industry sectors. MSCC seeks to partner with
entrepreneurs, business owners and management teams and generally provides "one stop" financing alternatives within its LMM portfolio.
MSCC and its consolidated subsidiaries invest primarily in secured debt investments, equity investments, warrants and other securities of
LMM companies based in the United States and in secured debt investments of Middle Market companies generally headquartered in the
United States.

       MSCC was formed in March 2007 to operate as an internally managed business development company ("BDC") under the Investment
Company Act of 1940, as amended (the "1940 Act"). MSCC wholly owns several investment funds, including Main Street Mezzanine
Fund, LP ("MSMF"), Main Street Capital II, LP ("MSC II") and Main Street Capital III, LP ("MSC III" and, collectively with MSMF and
MSC II, the "Funds"), and each of their general partners. The Funds are each licensed as a Small Business Investment Company ("SBIC")
by the United States Small Business Administration ("SBA"). Because MSCC is internally managed, all of the executive officers and other
employees are employed by MSCC. Therefore, MSCC does not pay any external investment advisory fees, but instead directly incurs the
operating costs associated with employing investment and portfolio management professionals.

       MSC Adviser I, LLC (the "External Investment Manager") was formed in November 2013 as a wholly owned subsidiary of MSCC to
provide investment management and other services to parties other than MSCC and its subsidiaries or their portfolio companies ("External
Parties") and receives fee income for such services. MSCC has been granted no-action relief by the Securities and Exchange Commission
("SEC") to allow the External Investment Manager to register as a registered investment adviser under the Investment Advisers Act of
1940, as amended. Since the External Investment Manager conducts all of its investment management activities for External Parties, it is
accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated
financial statements.

       MSCC has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M
of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSCC generally will not pay corporate-level U.S. federal
income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

       MSCC has certain direct and indirect wholly owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries").
The primary purpose of the Taxable Subsidiaries is to permit MSCC to hold equity investments in portfolio companies which are "pass-
through" entities for tax purposes.

       Unless otherwise noted or the context otherwise indicates, the terms "we," "us," "our," the "Company" and "Main Street" refer to
MSCC and its consolidated subsidiaries, which include the Funds and the Taxable Subsidiaries.

2.    Basis of Presentation

       Main Street's consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United
States of America ("U.S. GAAP"). The Company is an investment company following accounting and reporting guidance in Financial
Accounting Standards Board ("FASB")

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Accounting Standards Codification ("ASC") 946, Financial Services — Investment Companies ("ASC 946"). For each of the periods
presented herein, Main Street's consolidated financial statements include the accounts of MSCC and its consolidated subsidiaries. The
Investment Portfolio, as used herein, refers to all of Main Street's investments in LMM portfolio companies, investments in Middle Market
portfolio companies, Private Loan portfolio investments, Other Portfolio investments and the investment in the External Investment
Manager (see "Note C — Fair Value Hierarchy for Investments and Debentures — Portfolio Composition — Investment Portfolio
Composition" for additional discussion of Main Street's Investment Portfolio and definitions for the terms Private Loan and Other
Portfolio). Main Street's results of operations and cash flows for the years ended December 31, 2018, 2017 and 2016 and financial position
as of December 31, 2018 and 2017, are presented on a consolidated basis. The effects of all intercompany transactions between Main Street
and its consolidated subsidiaries have been eliminated in consolidation. Certain reclassifications have been made to prior period balances to
conform with the current presentation.

       Under ASC 946, Main Street is precluded from consolidating other entities in which Main Street has equity investments, including
those in which it has a controlling interest, unless the other entity is another investment company. An exception to this general principle in
ASC 946 occurs if Main Street holds a controlling interest in an operating company that provides all or substantially all of its services
directly to Main Street or to its portfolio companies. Accordingly, as noted above, MSCC's consolidated financial statements include the
financial position and operating results for the Funds and the Taxable Subsidiaries. Main Street has determined that all of its portfolio
investments do not qualify for this exception, including the investment in the External Investment Manager. Therefore, Main Street's
Investment Portfolio is carried on the consolidated balance sheet at fair value, as discussed further in Note B.1., with any adjustments to
fair value recognized as "Net Unrealized Appreciation (Depreciation)" on the consolidated statements of operations until the investment is
realized, usually upon exit, resulting in any gain or loss being recognized as a "Net Realized Gain (Loss)."

Portfolio Investment Classification

       Main Street classifies its Investment Portfolio in accordance with the requirements of the 1940 Act. Under the 1940 Act, (a) "Control
Investments" are defined as investments in which Main Street owns more than 25% of the voting securities or has rights to maintain greater
than 50% of the board representation, (b) "Affiliate Investments" are defined as investments in which Main Street owns between 5% and
25% of the voting securities and does not have rights to maintain greater than 50% of the board representation, and (c) "Non-Control/Non-
Affiliate Investments" are defined as investments that are neither Control Investments nor Affiliate Investments.

NOTE B — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1.    Valuation of the Investment Portfolio

       Main Street accounts for its Investment Portfolio at fair value. As a result, Main Street follows the provisions of ASC 820, Fair Value
Measurements and Disclosures ("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. ASC 820 requires Main Street to assume that the portfolio investment is to be sold in the principal market to independent
market participants, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal market that
are independent, knowledgeable and willing and able to transact.

       Main Street's portfolio strategy calls for it to invest primarily in illiquid debt and equity securities issued by privately held, LMM
companies and more liquid debt securities issued by Middle Market companies that

145

Table of Contents

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

are generally larger in size than the LMM companies. Main Street categorizes some of its investments in LMM companies and Middle
Market companies as Private Loan portfolio investments, which are primarily debt securities in privately held companies which have been
originated through strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt markets
as "club deals." Private Loan investments are typically similar in size, structure, terms and conditions to investments Main Street holds in
its LMM portfolio and Middle Market portfolio. Main Street's portfolio also includes Other Portfolio investments which primarily consist
of investments that are not consistent with the typical profiles for its LMM portfolio investments, Middle Market portfolio investments or
Private Loan portfolio investments, including investments which may be managed by third parties. Main Street's portfolio investments may
be subject to restrictions on resale.

       LMM investments and Other Portfolio investments generally have no established trading market while Middle Market securities
generally have established markets that are not active. Private Loan investments may include investments which have no established
trading market or have established markets that are not active. Main Street determines in good faith the fair value of its Investment
Portfolio pursuant to a valuation policy in accordance with ASC 820 and a valuation process approved by its Board of Directors and in
accordance with the 1940 Act. Main Street's valuation policies and processes are intended to provide a consistent basis for determining the
fair value of Main Street's Investment Portfolio.

       For LMM portfolio investments, Main Street generally reviews external events, including private mergers, sales and acquisitions
involving comparable companies, and includes these events in the valuation process by using an enterprise value waterfall methodology
("Waterfall") for its LMM equity investments and an income approach using a yield-to-maturity model ("Yield-to-Maturity") for its LMM
debt investments. For Middle Market portfolio investments, Main Street primarily uses quoted prices in the valuation process. Main Street
determines the appropriateness of the use of third-party broker quotes, if any, in determining fair value based on its understanding of the
level of actual transactions used by the broker to develop the quote and whether the quote was an indicative price or binding offer, the
depth and consistency of broker quotes and the correlation of changes in broker quotes with underlying performance of the portfolio
company and other market indices. For Middle Market and Private Loan portfolio investments in debt securities for which it has
determined that third-party quotes or other independent pricing are not available or appropriate, Main Street generally estimates the fair
value based on the assumptions that it believes hypothetical market participants would use to value the investment in a current hypothetical
sale using the Yield-to-Maturity valuation method. For its Other Portfolio equity investments, Main Street generally calculates the fair
value of the investment primarily based on the net asset value ("NAV") of the fund and adjusts the fair value for other factors that would
affect the fair value of the investment. All of the valuation approaches for Main Street's portfolio investments estimate the value of the
investment as if Main Street were to sell, or exit, the investment as of the measurement date.

       These valuation approaches consider the value associated with Main Street's ability to control the capital structure of the portfolio
company, as well as the timing of a potential exit. For valuation purposes, "control" portfolio investments are composed of debt and equity
securities in companies for which Main Street has a controlling interest in the equity ownership of the portfolio company or the ability to
nominate a majority of the portfolio company's board of directors. For valuation purposes, "non-control" portfolio investments are
generally composed of debt and equity securities in companies for which Main Street does not have a controlling interest in the equity
ownership of the portfolio company or the ability to nominate a majority of the portfolio company's board of directors.

       Under the Waterfall valuation method, Main Street estimates the enterprise value of a portfolio company using a combination of
market and income approaches or other appropriate valuation methods, such as considering recent transactions in the equity securities of
the portfolio company or third-party valuations of

146

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

the portfolio company, and then performs a waterfall calculation by allocating the enterprise value over the portfolio company's securities
in order of their preference relative to one another. The enterprise value is the fair value at which an enterprise could be sold in a transaction
between two willing parties, other than through a forced or liquidation sale. Typically, privately held companies are bought and sold based
on multiples of earnings before interest, taxes, depreciation and amortization ("EBITDA"), cash flows, net income, revenues, or in limited
cases, book value. There is no single methodology for estimating enterprise value. For any one portfolio company, enterprise value is
generally described as a range of values from which a single estimate of enterprise value is derived. In estimating the enterprise value of a
portfolio company, Main Street analyzes various factors including the portfolio company's historical and projected financial results. Due to
SEC deadlines for Main Street's quarterly and annual financial reporting, the operating results of a portfolio company used in the current
period valuation are generally the results from the period ended three months prior to such valuation date and may include unaudited,
projected, budgeted or pro forma financial information and may require adjustments for non-recurring items or to normalize the operating
results that may require significant judgment in its determination. In addition, projecting future financial results requires significant
judgment regarding future growth assumptions. In evaluating the operating results, Main Street also analyzes the impact of exposure to
litigation, loss of customers or other contingencies. After determining the appropriate enterprise value, Main Street allocates the enterprise
value to investments in order of the legal priority of the various components of the portfolio company's capital structure. In applying the
Waterfall valuation method, Main Street assumes the loans are paid off at the principal amount in a change in control transaction and are
not assumed by the buyer, which Main Street believes is consistent with its past transaction history and standard industry practices.

       Under the Yield-to-Maturity valuation method, Main Street also uses the income approach to determine the fair value of debt securities
based on projections of the discounted future free cash flows that the debt security will likely generate, including analyzing the discounted
cash flows of interest and principal amounts for the debt security, as set forth in the associated loan agreements, as well as the financial
position and credit risk of the portfolio company. Main Street's estimate of the expected repayment date of its debt securities is generally
the maturity date of the instrument, as Main Street generally intends to hold its loans and debt securities to maturity. The Yield-to-Maturity
analysis also considers changes in leverage levels, credit quality, portfolio company performance and other factors. Main Street will
generally use the value determined by the Yield-to-Maturity analysis as the fair value for that security; however, because of Main Street's
general intent to hold its loans to maturity, the fair value will not exceed the principal amount of the debt security valued using the Yield-
to-Maturity valuation method. A change in the assumptions that Main Street uses to estimate the fair value of its debt securities using the
Yield-to-Maturity valuation method could have a material impact on the determination of fair value. If there is deterioration in credit
quality or if a debt security is in workout status, Main Street may consider other factors in determining the fair value of the debt security,
including the value attributable to the debt security from the enterprise value of the portfolio company or the proceeds that would most
likely be received in a liquidation analysis.

       Under the NAV valuation method, for an investment in an investment fund that does not have a readily determinable fair value, Main
Street measures the fair value of the investment predominately based on the NAV of the investment fund as of the measurement date and
adjusts the investment's fair value for factors known to Main Street that would affect that fund's NAV, including, but not limited to, fair
values for individual investments held by the fund if Main Street holds the same investment or for a publicly traded investment. In addition,
in determining the fair value of the investment, Main Street considers whether adjustments to the NAV are necessary in certain
circumstances, based on the analysis of any restrictions on redemption of Main Street's investment as of the measurement date, recent
actual sales or redemptions of interests in the investment fund, and expected future cash flows available to equity holders, including the rate
of return on those cash flows compared to an implied market return on equity required by market

participants, or other uncertainties surrounding Main Street's ability to realize the full NAV of its interests in the investment fund.

       Pursuant to its internal valuation process and the requirements under the 1940 Act, Main Street performs valuation procedures on each
of its portfolio investments quarterly. In addition to its internal valuation process, in arriving at estimates of fair value for its investments in
its LMM portfolio companies, Main Street, among other things, consults with a nationally recognized independent financial advisory
services firm. The nationally recognized independent financial advisory services firm analyzes and provides observations,
recommendations and an assurance certification regarding the Company's determinations of the fair value of its LMM portfolio company
investments. The nationally recognized independent financial advisory services firm is generally consulted relative to Main Street's
investments in each LMM portfolio company at least once every calendar year, and for Main Street's investments in new LMM portfolio
companies, at least once in the twelve-month period subsequent to the initial investment. In certain instances, Main Street may determine
that it is not cost-effective, and as a result is not in its stockholders' best interest, to consult with the nationally recognized independent
financial advisory services firm on its investments in one or more LMM portfolio companies. Such instances include, but are not limited to,
situations where the fair value of Main Street's investment in a LMM portfolio company is determined to be insignificant relative to the
total Investment Portfolio. Main Street consulted with and received an assurance certification from its independent financial advisory
services firm in arriving at Main Street's determination of fair value on its investments in a total of 54 LMM portfolio companies for the
year ended December 31, 2018, representing approximately 87% of the total LMM portfolio at fair value as of December 31, 2018, and on
a total of 53 LMM portfolio companies for the year ended December 31, 2017, representing approximately 91% of the total LMM portfolio
at fair value as of December 31, 2017. Excluding its investments in new LMM portfolio companies which have not been in the Investment
Portfolio for at least twelve months subsequent to the initial investment as of December 31, 2018 and 2017, as applicable, or whose primary
purpose is to own real estate for which a third-party appraisal is obtained on at least an annual basis, the percentage of the LMM portfolio
reviewed and certified by its independent financial advisory services firm for the years ended December 31, 2018 and 2017 was 98% and
97% of the total LMM portfolio at fair value as of December 31, 2018 and 2017, respectively.

       For valuation purposes, all of Main Street's Middle Market portfolio investments are non-control investments. To the extent sufficient
observable inputs are available to determine fair value, Main Street uses observable inputs to determine the fair value of these investments
through obtaining third-party quotes or other independent pricing. For Middle Market portfolio investments for which it has determined
that third-party quotes or other independent pricing are not available or appropriate, Main Street generally estimates the fair value based on
the assumptions that it believes hypothetical market participants would use to value such Middle Market debt investments in a current
hypothetical sale using the Yield-to-Maturity valuation method and such Middle Market equity investments in a current hypothetical sale
using the Waterfall valuation method. Because the vast majority of the Middle Market portfolio investments are typically valued using
third-party quotes or other independent pricing services (including 94% and 95% of the Middle Market portfolio investments as of
December 31, 2018 and 2017, respectively), Main Street generally does not consult with any financial advisory services firms in connection
with determining the fair value of its Middle Market investments.

       For valuation purposes, all of Main Street's Private Loan portfolio investments are non-control investments. For Private Loan portfolio
investments for which it has determined that third-party quotes or other independent pricing are not available or appropriate, Main Street
generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value such Private
Loan debt investments in a current hypothetical sale using the Yield-to-Maturity valuation method and such Private Loan equity
investments in a current hypothetical sale using the Waterfall valuation method.

       In addition to its internal valuation process, in arriving at estimates of fair value for its investments in its Private Loan portfolio
companies, Main Street, among other things, consults with a nationally recognized independent financial advisory services firm. The
nationally recognized independent financial advisory services firm analyzes and provides observations and recommendations and an
assurance certification regarding the Company's determinations of the fair value of its Private Loan portfolio company investments. The
nationally recognized independent financial advisory services firm is generally consulted relative to Main Street's investments in each
Private Loan portfolio company at least once every calendar year, and for Main Street's investments in new Private Loan portfolio
companies, at least once in the twelve-month period subsequent to the initial investment. In certain instances, Main Street may determine
that it is not cost-effective, and as a result is not in its stockholders' best interest, to consult with the nationally recognized independent
financial advisory services firm on its investments in one or more Private Loan portfolio companies. Such instances include, but are not
limited to, situations where the fair value of Main Street's investment in a Private Loan portfolio company is determined to be insignificant
relative to the total Investment Portfolio. Main Street consulted with and received an assurance certification from its independent financial
advisory services firm in arriving at its determination of fair value on its investments in a total of 27 Private Loan portfolio companies for
the year ended December 31, 2018, representing approximately 57% of the total Private Loan portfolio at fair value as of December 31,
2018, and on a total of 26 Private Loan portfolio companies for the year ended December 31, 2017, representing approximately 57% of the
total Private Loan portfolio at fair value as of December 31, 2017. Excluding its investments in new Private Loan portfolio companies
which have not been in the Investment Portfolio for at least twelve months subsequent to the initial investment decision as of December 31,
2018 and 2017, as applicable, and its investments in its Private Loan portfolio companies that were not reviewed because the investment is
valued based upon third-party quotes or other independent pricing, the percentage of the Private Loan portfolio reviewed and certified by
its independent financial advisory services firm for the years ended December 31, 2018 and 2017 was 91% and 94% of the total Private
Loan portfolio at fair value as of December 31, 2018 and 2017, respectively.

       For valuation purposes, all of Main Street's Other Portfolio investments are non-control investments. Main Street's Other Portfolio
investments comprised 4.4% and 4.8% of Main Street's Investment Portfolio at fair value as of December 31, 2018 and 2017, respectively.
Similar to the LMM investment portfolio, market quotations for Other Portfolio equity investments are generally not readily available. For
its Other Portfolio equity investments, Main Street generally determines the fair value of these investments using the NAV valuation
method.

       For valuation purposes, Main Street's investment in the External Investment Manager is a control investment. Market quotations are
not readily available for this investment, and as a result, Main Street determines the fair value of the External Investment Manager using
the Waterfall valuation method under the market approach. In estimating the enterprise value, Main Street analyzes various factors,
including the entity's historical and projected financial results, as well as its size, marketability and performance relative to the population
of market comparables. This valuation approach estimates the value of the investment as if Main Street were to sell, or exit, the investment.
In addition, Main Street considers its ability to control the capital structure of the company, as well as the timing of a potential exit, in
connection with determining the fair value of the External Investment Manager.

       Due to the inherent uncertainty in the valuation process, Main Street's determination of fair value for its Investment Portfolio may
differ materially from the values that would have been determined had a ready market for the securities existed. In addition, 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 these investments to be materially different than the valuations currently assigned. Main

149

Table of Contents

Street determines the fair value of each individual investment and records changes in fair value as unrealized appreciation or depreciation.

       Main Street uses an internally developed portfolio investment rating system in connection with its investment oversight, portfolio
management and analysis and investment valuation procedures for its LMM portfolio companies. This system takes into account both
quantitative and qualitative factors of the LMM portfolio company and the investments held therein.

       The Board of Directors of Main Street has the final responsibility for overseeing, reviewing and approving, in good faith, Main Street's
determination of the fair value for its Investment Portfolio, as well as its valuation procedures, consistent with 1940 Act requirements.
Main Street believes its Investment Portfolio as of December 31, 2018 and 2017 approximates fair value as of those dates based on the
markets in which Main Street operates and other conditions in existence on those reporting dates.

2.    Use of Estimates

       The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements
and the reported amounts of revenue and expenses during the period. Actual results may differ from these estimates under different
conditions or assumptions. Additionally, as explained in Note B.1., the consolidated financial statements include investments in the
Investment Portfolio whose values have been estimated by Main Street with the oversight, review and approval by Main Street's Board of
Directors in the absence of readily ascertainable market values. Because of the inherent uncertainty of the Investment Portfolio valuations,
those estimated values may differ materially from the values that would have been determined had a ready market for the securities existed.

3.    Cash and Cash Equivalents

       Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less at the date of
purchase. Cash and cash equivalents are carried at cost, which approximates fair value.

       At December 31, 2018, cash balances totaling $50.3 million exceeded Federal Deposit Insurance Corporation insurance protection
levels, subjecting the Company to risk related to the uninsured balance. All of the Company's cash deposits are held at large established
high credit quality financial institutions and management believes that the risk of loss associated with any uninsured balances is remote.

4.    Interest, Dividend and Fee Income

       Main Street records interest and dividend income on the accrual basis to the extent amounts are expected to be collected. Dividend
income is recorded as dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to
make a distribution. In accordance with Main Street's valuation policies, Main Street evaluates accrued interest and dividend income
periodically for collectability. When a loan or debt security becomes 90 days or more past due, and if Main Street otherwise does not expect
the debtor to be able to service all of its debt or other obligations, Main Street will generally place the loan or debt security on non-accrual
status and cease recognizing interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay
contractual amounts due. If a loan or debt security's status significantly improves regarding the debtor's ability to service the debt or other
obligations, or if a loan or debt security is sold or written-off, Main Street removes it from non-accrual status.

150

Table of Contents

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

       As of December 31, 2018, Main Street's total Investment Portfolio had six investments on non-accrual status, which comprised
approximately 1.3% of its fair value and 3.9% of its cost. As of December 31, 2017, Main Street's total Investment Portfolio had five
investments on non-accrual status, which comprised approximately 0.2% of its fair value and 2.3% of its cost.

       Main Street holds certain debt and preferred equity instruments in its Investment Portfolio that contain payment-in-kind ("PIK") interest
and cumulative dividend provisions. The PIK interest, computed at the contractual rate specified in each debt agreement, is periodically
added to the principal balance of the debt and is recorded as interest income. Thus, the actual collection of this interest may be deferred
until the time of debt principal repayment. Cumulative dividends are recorded as dividend income, and any dividends in arrears are added
to the balance of the preferred equity investment. The actual collection of these dividends in arrears may be deferred until such time as the
preferred equity is redeemed or sold. To maintain RIC tax treatment (as discussed in Note B.9. below), these non-cash sources of income
may need to be paid out to stockholders in the form of distributions, even though Main Street may not have collected the PIK interest and
cumulative dividends in cash. Main Street stops accruing PIK interest and cumulative dividends and writes off any accrued and uncollected
interest and dividends in arrears when it determines that such PIK interest and dividends in arrears are no longer collectible. For the years
ended December 31, 2018, 2017 and 2016, (i) approximately 1.0%, 2.4% and 3.6%, respectively, of Main Street's total investment income
was attributable to PIK interest income not paid currently in cash and (ii) approximately 1.0%, 1.6% and 1.2%, respectively, of Main
Street's total investment income was attributable to cumulative dividend income not paid currently in cash.

       Main Street may periodically provide services, including structuring and advisory services, to its portfolio companies or other third
parties. For services that are separately identifiable and evidence exists to substantiate fair value, fee income is recognized as earned, which
is generally when the investment or other applicable transaction closes. Fees received in connection with debt financing transactions for
services that do not meet these criteria are treated as debt origination fees and are deferred and accreted into income over the life of the
financing.

       A presentation of the investment income Main Street received from its Investment Portfolio in each of the periods presented is as

       Deferred financing costs include commitment fees and other costs related to Main Street's multi-year revolving credit facility (the
"Credit Facility") and its notes, as well as the commitment fees and leverage fees (approximately 3.4% of the total commitment and draw
amounts, as applicable) on the SBIC debentures which are not accounted for under the fair value option under ASC 825 (as discussed
further in Note B.11.). See further discussion of Main Street's debt in Note E. Deferred financing costs in connection with the Credit
Facility are capitalized as an asset. Deferred financing costs in connection with all other debt arrangements not using the fair value option
are a direct deduction from the related debt liability.

6.    Equity Offering Costs

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

       The Company's offering costs are charged against the proceeds from equity offerings when the proceeds are received.

7.    Unearned Income — Debt Origination Fees and Original Issue Discount and Discounts/Premiums to Par Value

       Main Street capitalizes debt origination fees received in connection with financings and reflects such fees as unearned income netted
against the applicable debt investments. The unearned income from the fees is accreted into income based on the effective interest method
over the life of the financing.

       In connection with its portfolio debt investments, Main Street sometimes receives nominal cost warrants or warrants with an exercise
price below the fair value of the underlying equity (together, "nominal cost equity") that are valued as part of the negotiation process with
the particular portfolio company. When Main Street receives nominal cost equity, Main Street allocates its cost basis in its investment
between its debt security and its nominal cost equity at the time of origination based on amounts negotiated with the particular portfolio
company. The allocated amounts are based upon the fair value of the nominal cost equity, which is then used to determine the allocation of
cost to the debt security. Any discount recorded on a debt investment resulting from this allocation is reflected as unearned income, which
is netted against the applicable debt investment, and accreted into interest income based on the effective interest method over the life of the
debt investment. The actual collection of this interest is deferred until the time of debt principal repayment.

       Main Street may also purchase debt securities at a discount or at a premium to the par value of the debt security. In the case of a
purchase at a discount, Main Street records the investment at the par value of the debt security net of the discount, and the discount is
accreted into interest income based on the effective interest method over the life of the debt investment. In the case of a purchase at a
premium, Main Street records the investment at the par value of the debt security plus the premium, and the premium is amortized as a
reduction to interest income based on the effective interest method over the life of the debt investment.

       To maintain RIC tax treatment (as discussed in Note B.9. below), these non-cash sources of income may need to be paid out to
stockholders in the form of distributions, even though Main Street may not have collected the interest income. For the years ended
December 31, 2018, 2017 and 2016, approximately 3.0%, 3.6% and 3.1%, respectively, of Main Street's total investment income was
attributable to interest income from the accretion of discounts associated with debt investments, net of any premium reduction.

8.    Share-Based Compensation

       Main Street accounts for its share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation —
Stock Compensation. Accordingly, for restricted stock awards, Main Street measures the grant date fair value based upon the market price
of its common stock on the date of the grant and amortizes the fair value of the awards as share-based compensation expense over the
requisite service period, which is generally the vesting term.

       Main Street has also adopted Accounting Standards Update ("ASU") 2016-09, Compensation — Stock Compensation: Improvements to
Employee Share-Based Payment Accounting, which requires that all excess tax benefits and tax deficiencies (including tax benefits of
dividends on share-based payment awards) be recognized as income tax expense or benefit in the income statement and not delay
recognition of a tax benefit until the tax benefit is realized through a reduction to taxes payable. The tax effects of exercised or vested
awards should be treated as discrete items in the reporting period in which they occur. Additionally, Main Street has elected to account for
forfeitures as they occur.

9.    Income Taxes

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

       MSCC has elected to be treated for U.S. federal income tax purposes as a RIC. MSCC's taxable income includes the taxable income
generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as disregarded entities for tax purposes. As a
RIC, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that
MSCC distributes to its stockholders. MSCC must generally distribute at least 90% of its "investment company taxable income" (which is
generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and
90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC
status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be
distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (i) the
filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close of
the year in which such taxable income was generated.

       The Taxable Subsidiaries primarily hold certain portfolio investments for Main Street. The Taxable Subsidiaries permit Main Street to
hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the
"source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with Main
Street for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in Main
Street's consolidated financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated
with MSCC for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their
ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or
loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at their normal
corporate tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the
Taxable Subsidiaries are reflected in Main Street's consolidated financial statements.

       The External Investment Manager is an indirect wholly owned subsidiary of MSCC owned through a Taxable Subsidiary and is a
disregarded entity for tax purposes. The External Investment Manager has entered into a tax sharing agreement with its Taxable Subsidiary
owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a consolidated
subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its Taxable Subsidiary
owner, for its stand-alone financial reporting purposes the External Investment Manager is treated as if it is taxed at normal corporate tax
rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. The income tax expense, or
benefit, if any, and the related tax assets and liabilities, of the External Investment Manager are reflected in the External Investment
Manager's separate financial statements.

       In December 2017, the "Tax Cuts and Jobs Act" legislation was enacted. The Tax Cuts and Jobs Act includes significant changes to the
U.S. corporate tax system, including a U.S. federal corporate income tax rate reduction from 35% to 21% and other changes. ASC 740,
Income Taxes, requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the
legislation was enacted. As such, Main Street has accounted for the tax effects as a result of the enactment of the Tax Cuts and Jobs Act
beginning with the period ended December 31, 2017.

       The Taxable Subsidiaries and the External Investment Manager use the liability method in accounting for income taxes. Deferred tax
assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the
consolidated financial statements, using statutory tax

153

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

rates in effect for the year in which the temporary differences are expected to reverse. A valuation allowance is provided, if necessary,
against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized.

       Taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the
recognition of income and expenses. Taxable income generally excludes net unrealized appreciation or depreciation, as investment gains or
losses are not included in taxable income until they are realized.

10.  Net Realized Gains or Losses and Net Unrealized Appreciation or Depreciation

       Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of an investment or a
financial instrument and the cost basis of the investment or financial instrument, without regard to unrealized appreciation or depreciation
previously recognized, and includes investments written-off during the period net of recoveries and realized gains or losses from in-kind
redemptions. Net unrealized appreciation or depreciation reflects the net change in the fair value of the Investment Portfolio and financial
instruments and the reclassification of any prior period unrealized appreciation or depreciation on exited investments and financial
instruments to realized gains or losses.

11.  Fair Value of Financial Instruments

       Fair value estimates are made at discrete points in time based on relevant information. These estimates may be subjective in nature and
involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Main Street believes that the
carrying amounts of its financial instruments, consisting of cash and cash equivalents, receivables, payables and other liabilities
approximate the fair values of such items due to the short-term nature of these instruments.

       As part of Main Street's acquisition of the majority of the equity interests of MSC II in January 2010 (the "MSC II Acquisition"), Main
Street elected the fair value option under ASC 825, Financial Instruments ("ASC 825"), relating to accounting for debt obligations at their
fair value, for the MSC II SBIC debentures acquired as part of the acquisition accounting related to the MSC II Acquisition and values
those obligations as discussed further in Note C. In order to provide for a more consistent basis of presentation, Main Street has continued
to elect the fair value option for SBIC debentures issued by MSC II subsequent to the MSC II Acquisition. When the fair value option is
elected for a given SBIC debenture, the deferred loan costs associated with the debenture are fully expensed in the current period to "Net
Unrealized Appreciation (Depreciation) — SBIC debentures" as part of the fair value adjustment. Interest incurred in connection with
SBIC debentures which are valued at fair value is included in interest expense.

12.  Earnings per Share

       Basic and diluted per share calculations are computed utilizing the weighted-average number of shares of common stock outstanding
for the period. In accordance with ASC 260, Earnings Per Share, the unvested shares of restricted stock awarded pursuant to Main Street's
equity compensation plans are participating securities and, therefore, are included in the basic earnings per share calculation. As a result,
for all periods presented, there is no difference between diluted earnings per share and basic earnings per share amounts.

13.  Recently Issued or Adopted Accounting Standards

       In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the
revenue recognition requirements under ASC 605, Revenue Recognition, and most industry-specific guidance throughout the Industry
Topics of the ASC. The core principle of the

154

Table of Contents

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that
reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. Under the guidance, an entity is
required to perform the following five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the
contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract, and
(5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance will significantly enhance comparability of
revenue recognition practices across entities, industries, jurisdictions and capital markets. Additionally, the guidance requires improved
disclosures as to the nature, amount, timing and uncertainty of revenue that is recognized. In March 2016, the FASB issued ASU 2016-08,
Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which
clarified the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, Revenue
from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarified the implementation
guidance regarding performance obligations and licensing arrangements. In May 2016, the FASB issued ASU No. 2016-12, Revenue from
Contracts with Customers (Topic 606) — Narrow-Scope Improvements and Practical Expedients, which clarified guidance on assessing
collectability, presenting sales tax, measuring noncash consideration, and certain transition matters. In December 2016, the FASB issued
ASU No. 2016-20, Revenue from Contracts with Customers (Topic 606) — Technical Corrections and Improvements, which provided
disclosure relief, and clarified the scope and application of the new revenue standard and related cost guidance. The guidance is effective
for the annual reporting period beginning after December 15, 2017, including interim periods within that reporting period. Substantially all
of Main Street's income is not within the scope of ASU 2014-09. For those income items that are within the scope (primarily fee income),
Main Street has similar performance obligations as compared with deliverables and separate units of account previously identified. As a
result, Main Street's timing of its income recognition remains the same and the adoption of the standard was not material.

       In February 2016, the FASB issued ASU 2016-02, Leases, which requires lessees to recognize on the balance sheet a right-of-use
asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than
12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of
cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of
optional practical expedients that entities may elect to apply. The guidance is effective for annual periods beginning after December 15,
2018, and interim periods therein. Early application is permitted. While Main Street continues to assess the effect of adoption, Main Street
currently believes the most significant change relates to the recognition of a new right-of-use asset and lease liability on its consolidated
balance sheet for its office space operating lease. Main Street currently has one operating lease for office space and does not expect a
significant change in the leasing activity between now and adoption. See further discussion of the operating lease obligation in Note K.

       In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which is intended to reduce the existing
diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The
guidance is effective for annual periods beginning after December 15, 2017, and interim periods therein. Main Street has adopted
ASU 2016-15 and the impact of the adoption of this accounting standard on Main Street's consolidated financial statements was not
material.

       In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which is intended to improve fair value and
defined benefit disclosure requirements by removing disclosures that are not cost beneficial, clarifying disclosures' specific requirements,
and adding relevant disclosure requirements. The amendments take effect for all organizations for fiscal years, and interim periods within
those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Main Street elected to early adopt ASU 2018-13 in the
current annual period. No significant changes were made to the fair value disclosures in the notes to the consolidated financial statements
in order to comply with ASU 2018-13.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

       In August 2018, the SEC adopted rules (the "SEC Release") amending certain disclosure requirements intended to eliminate redundant,
duplicative, overlapping, outdated, or superseded, in light of other SEC disclosure requirements, US GAAP requirements, or changes in the
information environment. In part, the SEC Release requires an investment company to present distributable earnings in total on the
consolidated balance sheet and consolidated statement of changes in net assets, rather than showing the three components of distributable
earnings as previously shown. Main Street adopted this part of the SEC Release in the current annual period and the changes in
presentation have been retrospectively applied to the consolidated balance sheet as of December 31, 2017 and to the consolidated
statements of changes in net assets for the years ended December 31, 2017 and 2016. The impact of the adoption of these rules on Main
Street's consolidated financial statements was not material. Additionally, the SEC Release requires disclosure of changes in net assets
within a registrant's Form 10-Q filing on a quarter-to-date and year-to-date basis for both the current year and prior year comparative
periods. Main Street expects to adopt the new requirement to present changes in shareholders' equity in interim financial statements within
Form 10-Q filings starting with the quarter ending March 31, 2019. The compliance date for the SEC Release was for all filings, as
applicable, on or after November 5, 2018. The adoption of these rules will not have a material impact on the consolidated financial
statements.

       From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by Main
Street as of the specified effective date. Main Street believes that the impact of recently issued standards and any that are not yet effective
will not have a material impact on its consolidated financial statements upon adoption.

NOTE C — FAIR VALUE HIERARCHY FOR INVESTMENTS AND DEBENTURES — PORTFOLIO COMPOSITION

       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. Main Street accounts for its
investments at fair value.

Fair Value Hierarchy

       In accordance with ASC 820, Main Street has categorized its investments based on the priority of the inputs to the valuation technique
into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical
investments (Level 1) and the lowest priority to unobservable inputs (Level 3).

       Investments recorded on Main Street's balance sheet are categorized based on the inputs to the valuation techniques as follows:

       Level 1 — Investments whose values are based on unadjusted quoted prices for identical assets in an active market that Main
Street has the ability to access (examples include investments in active exchange-traded equity securities and investments in most
U.S. government and agency securities).

       Level 2 — Investments whose values are based on quoted prices in markets that are not active or model inputs that are
observable either directly or indirectly for substantially the full term of the investment. Level 2 inputs include the following:

•

•

Quoted prices for similar assets in active markets (for example, investments in restricted stock); 

Quoted prices for identical or similar assets in non-active markets (for example, investments in thinly traded public
companies);

156

Table of Contents

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

•

•

Pricing models whose inputs are observable for substantially the full term of the investment (for example, market
interest rate indices); and 

Pricing models whose inputs are derived principally from, or corroborated by, observable market data through
correlation or other means for substantially the full term of the investment.

       Level 3 — Investments whose values are based on prices or valuation techniques that require inputs that are both unobservable
and significant to the overall fair value measurement (for example, investments in illiquid securities issued by privately held
companies). These inputs reflect management's own assumptions about the assumptions a market participant would use in pricing
the investment.

       As required by ASC 820, when the inputs used to measure fair value fall within different levels of the hierarchy, the level within which
the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety.
For example, a Level 3 fair value measurement may include inputs that are observable (Levels 1 and 2) and unobservable (Level 3).
Therefore, unrealized appreciation and depreciation related to such investments categorized within the Level 3 tables below may include
changes in fair value that are attributable to both observable inputs (Levels 1 and 2) and unobservable inputs (Level 3).

       As of December 31, 2018 and 2017, all of Main Street's LMM portfolio investments consisted of illiquid securities issued by privately
held companies. As a result, the fair value determination for all of Main Street's LMM portfolio investments primarily consisted of
unobservable inputs. As a result, all of Main Street's LMM portfolio investments were categorized as Level 3 as of December 31, 2018 and
2017

       As of December 31, 2018 and 2017, Main Street's Middle Market portfolio investments consisted primarily of investments in secured
and unsecured debt investments and independently rated debt investments. The fair value determination for these investments consisted of
a combination of observable inputs in non-active markets for which sufficient observable inputs were not available to determine the fair
value of these investments and unobservable inputs. As a result, all of Main Street's Middle Market portfolio investments were categorized
as Level 3 as of December 31, 2018 and 2017.

       As of December 31, 2018 and 2017, Main Street's Private Loan portfolio investments primarily consisted of investments in interest-
bearing secured debt investments. The fair value determination for these investments consisted of a combination of observable inputs in
non-active markets for which sufficient observable inputs were not available to determine the fair value of these investments and
unobservable inputs. As a result, all of Main Street's Private Loan portfolio investments were categorized as Level 3 as of December 31,
2018 and 2017.

       As of December 31, 2018 and 2017, Main Street's Other Portfolio investments consisted of illiquid securities issued by privately held
companies. The fair value determination for these investments primarily consisted of unobservable inputs. As a result, all of Main Street's
Other Portfolio investments were categorized as Level 3 as of December 31, 2018 and 2017.

       The fair value determination of each portfolio investment categorized as Level 3 required one or more of the following unobservable
inputs:

•

•

•

Financial information obtained from each portfolio company, including unaudited statements of operations and
balance sheets for the most recent period available as compared to budgeted numbers; 

Current and projected financial condition of the portfolio company; 

Current and projected ability of the portfolio company to service its debt obligations;

157

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Type and amount of collateral, if any, underlying the investment; 

Current financial ratios (e.g., fixed charge coverage ratio, interest coverage ratio and net debt/EBITDA ratio)
applicable to the investment; 

Current liquidity of the investment and related financial ratios (e.g., current ratio and quick ratio); 

Pending debt or capital restructuring of the portfolio company; 

Projected operating results of the portfolio company; 

Current information regarding any offers to purchase the investment; 

Current ability of the portfolio company to raise any additional financing as needed; 

Changes in the economic environment which may have a material impact on the operating results of the portfolio
company; 

Internal occurrences that may have an impact (both positive and negative) on the operating performance of the
portfolio company; 

Qualitative assessment of key management; 

Contractual rights, obligations or restrictions associated with the investment; and 

Other factors deemed relevant.

       The use of significant unobservable inputs creates uncertainty in the measurement of fair value as of the reporting date. The significant
unobservable inputs used in the fair value measurement of Main Street's LMM equity securities, which are generally valued through an
average of the discounted cash flow technique and the market comparable/enterprise value technique (unless one of these approaches is
determined to not be appropriate), are (i) EBITDA multiples and (ii) the weighted-average cost of capital ("WACC"). Significant increases
(decreases) in EBITDA multiple inputs in isolation would result in a significantly higher (lower) fair value measurement. On the contrary,
significant increases (decreases) in WACC inputs in isolation would result in a significantly lower (higher) fair value measurement. The
significant unobservable inputs used in the fair value measurement of Main Street's LMM, Middle Market and Private Loan securities are
(i) risk adjusted discount rates used in the Yield-to-Maturity valuation technique (see "Note B.1. — Valuation of the Investment Portfolio")
and (ii) the percentage of expected principal recovery. Significant increases (decreases) in any of these discount rates in isolation would
result in a significantly lower (higher) fair value measurement. Significant increases (decreases) in any of these expected principal recovery
percentages in isolation would result in a significantly higher (lower) fair value measurement. However, due to the nature of certain
investments, fair value measurements may be based on other criteria, such as third-party appraisals of collateral and fair values as
determined by independent third parties, which are not presented in the tables below.

Includes the impact of non-cash conversions. These transactions represent non-cash investing activities. See additional
cash flow information at the consolidated statements of cash flows.

       As of December 31, 2018 and 2017, the fair value determination for the SBIC debentures recorded at fair value primarily consisted of
unobservable inputs. As a result, the SBIC debentures which are recorded at fair value were categorized as Level 3. Main Street determines
the fair value of these instruments primarily using a Yield-to-Maturity approach that analyzes the discounted cash flows of interest and
principal for each SBIC debenture recorded at fair value based on estimated market interest rates for debt instruments of similar structure,
terms, and maturity. Main Street's estimate of the expected repayment date of principal for each SBIC debenture recorded at fair value is
the legal maturity date of the instrument. The significant unobservable inputs used in the fair value measurement of Main Street's SBIC
debentures recorded at fair value are the estimated market interest rates used to fair value each debenture using the yield valuation
technique described above. Significant increases (decreases) in the estimated market interest rates in isolation would result in a significantly
lower (higher) fair value measurement.

       The following tables provide a summary of the significant unobservable inputs used to fair value Main Street's Level 3 SBIC
debentures as of December 31, 2018 and 2017 (amounts in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Investment Portfolio Composition

       Main Street's LMM portfolio investments primarily consist of secured debt, equity warrants and direct equity investments in privately
held, LMM companies based in the United States. Main Street's LMM portfolio companies generally have annual revenues between
$10 million and $150 million, and its LMM investments generally range in size from $5 million to $50 million. The LMM debt
investments are typically secured by either a first or second priority lien on the assets of the portfolio company, can include either fixed or
floating rate terms and generally have a term of between five and seven years from the original investment date. In most LMM portfolio
investments, Main Street receives nominally priced equity warrants and/or makes direct equity investments in connection with a debt
investment.

       Main Street's Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing
debt securities in privately held companies based in the United States that are generally larger in size than the companies included in Main
Street's LMM portfolio. Main Street's Middle Market portfolio companies generally have annual revenues between $150 million and
$1.5 billion, and its Middle Market investments generally range in size from $3 million to $20 million. Main Street's Middle Market
portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically
have a term of between three and seven years from the original investment date.

       Main Street's private loan ("Private Loan") portfolio investments are primarily debt securities in privately held companies which have
been originated through strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt
markets as "club deals." Private Loan investments are typically similar in size, structure, terms and conditions to investments Main Street
holds in its LMM portfolio and Middle Market portfolio. Main Street's Private Loan portfolio debt investments are generally secured by
either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven years from
the original investment date.

       Main Street's other portfolio ("Other Portfolio") investments primarily consist of investments which are not consistent with the typical
profiles for LMM, Middle Market and Private Loan portfolio investments, including investments which may be managed by third parties.
In the Other Portfolio, Main Street may incur indirect fees and expenses in connection with investments managed by third parties, such as
investments in other investment companies or private funds. For Other Portfolio investments, Main Street generally receives distributions
related to the assets held by the portfolio company. Those assets are typically expected to be liquidated over a five to ten year period.

       Main Street's external asset management business is conducted through its External Investment Manager. The External Investment
Manager earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest,
based on the performance of the funds managed. Main Street entered into an agreement with the External Investment Manager to share
employees in connection with its asset management business generally, and specifically for its relationship with HMS Income Fund, Inc.
("HMS Income"). Through this agreement, Main Street shares employees with the External Investment Manager, including their related
infrastructure, business relationships, management expertise and capital raising capabilities. Main Street allocates the related expenses to
the External Investment Manager pursuant to the sharing agreement. Main Street's total expenses for the years ended December 31, 2018,
2017 and 2016 are net of expenses allocated to the External Investment Manager of $6.8 million, $6.4 million and $5.1 million,
respectively.

       Investment income, consisting of interest, dividends and fees, can fluctuate dramatically due to various factors, including the level of
new investment activity, repayments of debt investments or sales of equity interests. Investment income in any given year could also be
highly concentrated among several portfolio

companies. For the years ended December 31, 2018, 2017 and 2016, Main Street did not record investment income from any single
portfolio company in excess of 10% of total investment income.

       The following tables provide a summary of Main Street's investments in the LMM, Middle Market and Private Loan portfolios as of
December 31, 2018 and 2017 (this information excludes the Other Portfolio investments and the External Investment Manager which are

At December 31, 2018, Main Street had equity ownership in approximately 99% of its LMM portfolio companies, and
the average fully diluted equity ownership in those portfolio companies was approximately 40%. 

The weighted-average annual effective yields were computed using the effective interest rates for all debt investments
at cost as of December 31, 2018, including amortization of deferred debt origination fees and accretion of original
issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-
accrual status. The weighted-average annual effective yield is higher than what an investor in shares of Main Street's
common stock will realize on its investment because it does not reflect Main Street's expenses or any sales load paid
by an investor. 

The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the
Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including two
LMM portfolio companies, one Middle Market portfolio company and four Private Loan portfolio companies, as
EBITDA is not a meaningful valuation metric for Main Street's

At December 31, 2017, Main Street had equity ownership in approximately 97% of its LMM portfolio companies, and
the average fully diluted equity ownership in those portfolio companies was approximately 39%. 

The weighted-average annual effective yields were computed using the effective interest rates for all debt investments
at cost as of December 31, 2017, including amortization of deferred debt origination fees and accretion of original
issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-
accrual status. The weighted-average annual effective yield is higher than what an investor in shares of Main Street's
common stock will realize on its investment because it does not reflect Main Street's expenses or any sales load paid
by an investor. 

The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the
Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including six
LMM portfolio companies, one Middle Market portfolio company and three Private Loan portfolio companies, as
EBITDA is not a meaningful valuation metric for Main Street's investments in these portfolio companies, and those
portfolio companies whose primary purpose is to own real estate.

       As of December 31, 2018, Main Street had Other Portfolio investments in eleven companies, collectively totaling approximately
$108.3 million in fair value and approximately $116.0 million in cost basis and which comprised approximately 4.4% of Main Street's
Investment Portfolio at fair value. As of December 31, 2017, Main Street had Other Portfolio investments in eleven companies, collectively
totaling approximately $104.6 million in fair value and approximately $109.4 million in cost basis and which comprised approximately
4.8% of Main Street's Investment Portfolio at fair value.

       As discussed further in Note A.1., Main Street holds an investment in the External Investment Manager, a wholly owned subsidiary
that is treated as a portfolio investment. As of December 31, 2018, there was no cost basis in this investment and the investment had a fair
value of approximately $65.7 million, which comprised approximately 2.7% of Main Street's Investment Portfolio at fair value. As of
December 31, 2017, there was no cost basis in this investment and the investment had a fair value of approximately $41.8 million, which
comprised approximately 1.9% of Main Street's Investment Portfolio at fair value.

Unconsolidated Significant Subsidiaries

       In accordance with Rules 3-09 and 4-08(g) of Regulation S-X, Main Street must determine which of its unconsolidated controlled

Street's Control Investments (as defined in Note A, including those unconsolidated portfolio companies defined as Control Investments in
which Main Street does not own greater than 50% of the voting securities) are considered significant subsidiaries: the investment test, the
asset test and the income test. The income test is measured by dividing the absolute value of the combined total of total investment income,
net realized gain (loss) and net unrealized appreciation (depreciation) from each Control Investment for the period being tested by the
absolute value of Main Street's pre-tax income for the same period. Rule 3-09 of Regulation S-X, as interpreted by the SEC, requires Main
Street to include separate audited financial statements of an unconsolidated majority-owned subsidiary (Control Investments in which Main
Street owns greater than 50% of the voting securities) in an annual report if any of the three tests exceed 20% of Main Street's total
investments at fair value, total assets or total income, respectively. Rule 4-08(g) of Regulation S-X requires summarized financial
information of a Control Investment in an annual report if any of the three tests exceeds 10% of Main Street's annual total amounts and
Rule 10-01(b)(1) of Regulation S-X requires summarized financial information in a quarterly report if any of the three tests exceeds 20% of
Main Street's year-to-date total amounts.

       As of December 31, 2018 and 2017, Main Street had no single investment that represented greater than 10% of its total Investment
Portfolio at fair value and no single investment whose total assets represented greater than 10% of its total assets. After performing the
income test for the year ended December 31, 2018, Main Street determined that its income from three of its Control Investments
individually generated more than 10% of its total income, primarily due to the unrealized appreciation that was recognized on the
investments. As such, Gamber Johnson Holdings, LLC ("GJH"), GRT Rubber Technologies LLC ("GRT") and the wholly owned External
Investment Manager were each considered significant subsidiaries at the 10% income level (see further discussion and summarized
financial information of the External Investment Manager in Note D). Additionally, after performing the income test for the years ended
December 31, 2017 and 2016, Main Street determined that its income from one of its Control Investments individually generated more than
10% of its total income, primarily due to unrealized appreciation that was recognized on the investment. As such, CBT Nuggets, LLC
("CBT"), an unconsolidated portfolio company that was a Control Investment, but for which Main Street was not the majority owner and
did not have rights to maintain greater than 50% of the board representation, was considered a significant subsidiary at the 10% level as of
December 31, 2017 and 2016.

NOTE D — EXTERNAL INVESTMENT MANAGER

       As discussed further in Note A.1., the External Investment Manager provides investment management and other services to External
Parties. The External Investment Manager is accounted for as a portfolio investment of MSCC since the External Investment Manager
conducts all of its investment management activities for External Parties.

       During May 2012, Main Street entered into an investment sub-advisory agreement with HMS Adviser, LP ("HMS Adviser"), which is
the investment advisor to HMS Income, a non-listed BDC, to

provide certain investment advisory services to HMS Adviser. In December 2013, after obtaining required no-action relief from the SEC to
allow it to own a registered investment adviser, Main Street assigned the sub-advisory agreement to the External Investment Manager since
the fees received from such arrangement could otherwise have negative consequences on MSCC's ability to meet the source-of-income
requirement necessary for it to maintain its RIC tax treatment. Under the investment sub-advisory agreement, the External Investment
Manager is entitled to 50% of the base management fee and the incentive fees earned by HMS Adviser under its advisory agreement with
HMS Income. The External Investment Manager has conditionally agreed to waive the historical incentive fees otherwise earned. During
the years ended December 31, 2018, 2017 and 2016, the External Investment Manager earned $11.6 million, $10.9 million and
$9.5 million, respectively, of management fees (net of fees waived, if any) under the sub-advisory agreement with HMS Adviser.

       The investment in the External Investment Manager is accounted for using fair value accounting, with the fair value determined by
Main Street and approved, in good faith, by Main Street's Board of Directors. Main Street determines the fair value of the External
Investment Manager using the Waterfall valuation method under the market approach (see further discussion in Note B.1.). Any change in
fair value of the investment in the External Investment Manager is recognized on Main Street's consolidated statements of operations in
"Net Unrealized Appreciation (Depreciation) — Control investments."

       The External Investment Manager is an indirect wholly owned subsidiary of MSCC owned through a Taxable Subsidiary and is a
disregarded entity for tax purposes. The External Investment Manager has entered into a tax sharing agreement with its Taxable Subsidiary
owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a consolidated
subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its Taxable Subsidiary
owner, for financial reporting purposes the External Investment Manager is treated as if it is taxed at normal corporate tax rates based on its
taxable income and, as a result of its activities, may generate income tax expense or benefit. Main Street owns the External Investment
Manager through the Taxable Subsidiary to allow MSCC to continue to comply with the "source-of-income" requirements contained in the
RIC tax provisions of the Code. The taxable income, or loss, of the External Investment Manager may differ from its book income, or loss,
due to temporary book and tax timing differences and permanent differences. As a result of the above described financial reporting and tax
treatment, the External Investment Manager provides for any income tax expense, or benefit, and any tax assets or liabilities in its separate
financial statements.

       Main Street shares employees with the External Investment Manager and allocates costs related to such shared employees to the
External Investment Manager generally based on a combination of the direct time spent, new investment origination activity and assets
under management, depending on the nature of the expense. For the years ended December 31, 2018, 2017 and 2016, Main Street allocated
$6.8 million, $6.4 million and $5.1 million of total expenses, respectively, to the External Investment Manager. The total contribution of
the External Investment Manager to Main Street's net investment income consists of the combination of the expenses allocated to the
External Investment Manager and the dividend income received from the External Investment Manager. For the years ended December 31,
2018, 2017 and 2016, the total contribution to Main Street's net investment income was $10.6 million, $9.4 million and $7.9 million,
respectively.

NOTE E — DEBT

SBIC Debentures

       Under existing SBA regulations, SBA approved SBICs under common control have the ability to issue debentures guaranteed by the
SBA up to a regulatory maximum amount of $350.0 million. Main Street, through the Funds, has an effective maximum amount of
$346.0 million following the prepayment of $4.0 million of existing SBIC debentures as discussed below. SBIC debentures payable were
$345.8 million and $295.8 million at December 31, 2018 and 2017, respectively. SBIC debentures provide for interest to be paid
semiannually, with principal due at the applicable 10-year maturity date of each debenture. During the year ended December 31, 2018,
Main Street issued $54.0 million of SBIC debentures and opportunistically prepaid $4.0 million of existing SBIC debentures as part of an
effort to manage the maturity dates of the oldest SBIC debentures. As a result of this prepayment, Main Street recognized a realized loss of
$1.4 million due to the previously recognized gain recorded as a result of recording the MSC II debentures at fair value on the date of the
acquisition of the majority interests of MSC II. The effect of the realized loss is offset by the reversal of all previously recognized
unrealized depreciation due to fair value adjustments since the date of the acquisition. Main Street expects to issue new SBIC debentures
under the SBIC program in the future in an amount up to the regulatory maximum amount for affiliated SBIC funds. The weighted-average
annual

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

interest rate on the SBIC debentures was 3.7% and 3.6% as of December 31, 2018 and 2017, respectively. The first principal maturity due
under the existing SBIC debentures is in 2019, and the weighted-average remaining duration as of December 31, 2018 was approximately
5.6 years. For the years ended December 31, 2018, 2017 and 2016, Main Street recognized interest expense, including the amortization of
upfront leverage and other miscellaneous fees, attributable to the SBIC debentures of $12.8 million, $10.5 million and $10.0 million,
respectively. In accordance with SBA regulations, the Funds are precluded from incurring additional non-SBIC debt without the prior
approval of the SBA.

       As of December 31, 2018, the recorded value of the SBIC debentures was $338.2 million which consisted of (i) $44.7 million recorded
at fair value, or $1.3 million less than the $46.0 million par value of the SBIC debentures issued in MSC II, (ii) $149.8 million par value of
SBIC debentures outstanding held in MSMF, with a recorded value of $148.0 million that was net of unamortized debt issuance costs of
$1.8 million and (iii) $150.0 million par value of SBIC debentures held in MSC III with a recorded value of $145.5 million that was net of
unamortized debt issuance costs of $4.5 million. As of December 31, 2018, if Main Street had adopted the fair value option under ASC 825
for all of its SBIC debentures, Main Street estimates the fair value of its SBIC debentures would be approximately $310.0 million, or
$35.8 million less than the $345.8 million face value of the SBIC debentures.

Credit Facility

       Main Street maintains the Credit Facility to provide additional liquidity to support its investment and operational activities. The Credit
Facility was amended and restated during 2018 to provide for an increase in total commitments from $585.0 million to $705.0 million and
to increase the diversified group of lenders to eighteen, eliminate interest rate adjustments previously subject to Main Street's maintenance
of an investment grade rating and extend the final maturity by two years to September 2023. The amended Credit Facility also contains an
upsized accordion feature which allows Main Street to increase the total commitments under the

facility to up to $800.0 million from new and existing lenders on the same terms and conditions as the existing commitments.

       Borrowings under the Credit Facility bear interest, subject to Main Street's election, on a per annum basis at a rate equal to the
applicable LIBOR rate (2.5% as of December 31, 2018) plus (i) 1.875% (or the applicable base rate (Prime Rate of 5.5% as of
December 31, 2018) plus 0.875%) as long as Main Street meets certain agreed upon excess collateral and maximum leverage requirements
or (ii) 2.0% (or the applicable base rate plus 1.0%) otherwise. Main Street pays unused commitment fees of 0.25% per annum on the
unused lender commitments under the Credit Facility. The Credit Facility is secured by a first lien on the assets of MSCC and its
subsidiaries, excluding the equity ownership or assets of the Funds and the External Investment Manager. The Credit Facility contains
certain affirmative and negative covenants, including but not limited to: (i) maintaining a minimum availability of at least 10% of the
borrowing base, (ii) maintaining an interest coverage ratio of at least 2.0 to 1.0, (iii) maintaining an asset coverage ratio (tangible net worth
to Credit Facility borrowings) of at least 1.5 to 1.0 and (iv) maintaining a minimum tangible net worth. The Credit Facility is provided on a
revolving basis through its final maturity date in September 2023, and contains two, one-year extension options which could extend the
final maturity by up to two years, subject to certain conditions, including lender approval.

       At December 31, 2018, Main Street had $301.0 million in borrowings outstanding under the Credit Facility. As of December 31, 2018,
if Main Street had adopted the fair value option under ASC 825 for its Credit Facility, Main Street estimates its fair value would
approximate its recorded value. Main Street recognized interest expense related to the Credit Facility, including unused commitment fees
and amortization of deferred issuance costs, of $11.7 million, $10.6 million and $9.2 million, respectively, for the years ended
December 31, 2018, 2017 and 2016. As of December 31, 2018, the interest rate on the Credit Facility was 4.2% and the average interest
rate for the year ended December 31, 2018 was 3.9%. As of December 31, 2018, Main Street was in compliance with all financial
covenants of the Credit Facility.

6.125% Notes

       In April 2013,Main Street issued $92.0 million, including the underwriters' full exercise of their option to purchase additional principal
amounts to cover over-allotments, in aggregate principal amount of 6.125% Notes due 2023 (the "6.125% Notes"). The 6.125% Notes bore
interest at a rate of 6.125% per year payable quarterly on January 1, April 1, July 1 and October 1 of each year. The total net proceeds to
Main Street from the 6.125% Notes, after underwriting discounts and estimated offering expenses payable, were approximately
$89.0 million. On April 2, 2018, Main Street redeemed the entire principal amount of the issued and outstanding 6.125% Notes effective
April 1, 2018 (the "Redemption Date"). The 6.125% Notes were redeemed at par value, plus the accrued and unpaid interest thereon from
January 1, 2018, through, but excluding, the Redemption Date. As part of the redemption, Main Street recognized a realized loss on
extinguishment of debt of $1.5 million in the second quarter of 2018 related to the write-off of the related unamortized deferred financing
costs. Main Street recognized interest expense related to the 6.125% Notes, including amortization of unamortized deferred issuance costs,
of $1.5 million for the year ended December 31 2018 and $5.9 million for each of the years ended December 31, 2017 and 2016.

4.50% Notes due 2019

       In November 2014, Main Street issued $175.0 million in aggregate principal amount of 4.50% unsecured notes due 2019 (the "4.50%
Notes due 2019") at an issue price of 99.53%. The 4.50% Notes due 2019 are unsecured obligations and rank pari passu with Main Street's
current and future unsecured indebtedness; senior to any of its future indebtedness that expressly provides it is subordinated to the 4.50%
Notes due 2019; effectively subordinated to all of its existing and future secured indebtedness, to the extent of the value

174

MAIN STREET CAPITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

of the assets securing such indebtedness, including borrowings under the Credit Facility; and structurally subordinated to all existing and
future indebtedness and other obligations of any of its subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50%
Notes due 2019 mature on December 1, 2019, and may be redeemed in whole or in part at any time at Main Street's option subject to certain
make-whole provisions. The 4.50% Notes due 2019 bear interest at a rate of 4.50% per year payable semiannually on June 1 and
December 1 of each year. The total net proceeds from the 4.50% Notes due 2019, resulting from the issue price and after underwriting
discounts and estimated offering expenses payable, were approximately $171.2 million. Main Street may from time to time repurchase the
4.50% Notes due 2019 in accordance with the 1940 Act and the rules promulgated thereunder. As of December 31, 2018, the outstanding
balance of the 4.50% Notes due 2019 was $175.0 million and the recorded value of $174.3 million was net of unamortized debt issuance
costs of $0.7 million. As of December 31, 2018, if Main Street had adopted the fair value option under ASC 825 for the 4.50% Notes due
2019, Main Street estimates its fair value would be approximately $175.0 million. Main Street recognized interest expense related to the
4.50% Notes due 2019, including amortization of unamortized deferred issuance costs, of $8.6 million for each of the years ended
December 31, 2018, 2017 and 2016.

       The indenture governing the 4.50% Notes due 2019 (the "4.50% Notes due 2019 Indenture") contains certain covenants, including
covenants requiring Main Street's compliance with (regardless of whether Main Street is subject to) the asset coverage requirements set
forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring Main Street to provide
financial information to the holders of the 4.50% Notes due 2019 and the Trustee if Main Street ceases to be subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These covenants are subject to limitations and
exceptions that are described in the 4.50% Notes due 2019 Indenture. As of December 31, 2018, Main Street was in compliance with these
covenants.

4.50% Notes due 2022

       In November 2017, Main Street issued $185.0 million in aggregate principal amount of 4.50% unsecured notes due 2022 (the "4.50%
Notes due 2022") at an issue price of 99.16%. The 4.50% Notes due 2022 are unsecured obligations and rank pari passu with Main Street's
current and future unsecured indebtedness; senior to any of its future indebtedness that expressly provides it is subordinated to the 4.50%
Notes due 2022; effectively subordinated to all of its existing and future secured indebtedness, to the extent of the value of the assets
securing such indebtedness, including borrowings under its Credit Facility; and structurally subordinated to all existing and future
indebtedness and other obligations of any of its subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50% Notes
due 2022 mature on December 1, 2022, and may be redeemed in whole or in part at any time at Main Street's option subject to certain
make-whole provisions. The 4.50% Notes due 2022 bear interest at a rate of 4.50% per year payable semiannually on June 1 and
December 1 of each year. The total net proceeds from the 4.50% Notes due 2022, resulting from the issue price and after underwriting
discounts and estimated offering expenses payable, were approximately $182.2 million. Main Street may from time to time repurchase the
4.50% Notes due 2022 in accordance with the 1940 Act and the rules promulgated thereunder. As of December 31, 2018, the outstanding
balance of the 4.50% Notes due 2022 was $185.0 million and the recorded value of $182.6 million was net of unamortized debt issuance
costs of $2.4 million. As of December 31, 2018, if Main Street had adopted the fair value option under ASC 825 for the 4.50% Notes due
2022, Main Street estimates its fair value would be approximately $186.2 million. Main Street recognized interest expense related to the
4.50% Notes due 2022, including amortization of unamortized deferred issuance costs, of $9.0 million and $0.9 million for the years ended
December 31, 2018 and 2017, respectively.

       The indenture governing the 4.50% Notes due 2022 (the "4.50% Notes due 2022 Indenture") contains certain covenants, including
covenants requiring Main Street's compliance with (regardless of whether Main

well as covenants requiring Main Street to provide financial information to the holders of the 4.50% Notes due 2022 and the Trustee if
Main Street ceases to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and

Total expenses are the sum of operating expenses and net income tax provision/benefit. Net income tax
provision/benefit includes the accrual of net deferred tax provision/benefit relating to the net unrealized
appreciation/depreciation on portfolio investments held in Taxable Subsidiaries and due to the change in the loss
carryforwards, which are non-cash in nature and may vary significantly from period to period. Main Street is required
to include net deferred tax provision/benefit in calculating its total expenses even though these net deferred taxes are
not currently payable/receivable. 

Unless otherwise noted, operating expenses include interest, compensation, general and administrative and share-
based compensation expenses, net of expenses allocated to the External Investment Manager. 

Total investment return is based on the purchase of stock at the current market price on the first day and a sale at the
current market price on the last day of each period reported on the table and assumes reinvestment of dividends at
prices obtained by Main Street's dividend reinvestment plan during the period. The return does not reflect any sales
load that may be paid by an investor. 

Total return is based on change in net asset value was calculated using the sum of ending net asset value plus
dividends to stockholders and other non-operating changes during the period, as divided by the beginning net asset
value. Non-operating changes include any items that affect net asset value other than the net increase in net assets
resulting from operations, such as the effects of stock offerings, shares issued under the DRIP and equity incentive
plans and other miscellaneous items.

NOTE G — DIVIDENDS, DISTRIBUTIONS AND TAXABLE INCOME

       During 2018, Main Street paid supplemental dividends of $0.275 per share in each of June and December 2018, regular monthly
dividends of $0.190 per share for each month of January through September 2018, regular monthly dividends of $0.195 per share for each
month of October through December 2018, with such dividends totaling $170.9 million, or $2.845 per share. The 2018 regular monthly
dividends, which total $137.5 million, or $2.295 per share, represent a 2.7% increase from the regular monthly dividends paid per share for
the year ended 2017. For tax purposes, the 2018 dividends, which included the effects of dividends on an accrual basis, total $2.85 per
share and were comprised of (i) ordinary income totaling approximately $2.270 per share, (ii) long term capital gain totaling approximately
$0.375 per share, and (iii) qualified dividend income totaling approximately $0.205 per share. As of December 31, 2018, Main Street
estimates that it has generated undistributed taxable income of approximately $53.4 million, or $0.87 per share, that will be carried forward
toward distributions to be paid in 2019. For the years ended

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

December 31, 2017 and 2016, Main Street paid total dividends of approximately $157.6 million, or $2.785 per share, and $141.6 million, or
$2.725 per share, respectively.

       MSCC has elected to be treated for U.S. federal income tax purposes as a RIC. MSCC's taxable income includes the taxable income
generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as disregarded entities for tax purposes. As a
RIC, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that
MSCC distributes to its stockholders. MSCC must generally distribute at least 90% of its "investment company taxable income" (which is
generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and
90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC
status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be
distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of
(i) filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close
of the year in which such taxable income was generated.

       Ordinary dividend distributions from a RIC do not qualify for the 20% maximum tax rate (plus a 3.8% Medicare surtax, if applicable)
on dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in
the form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will
generally include both ordinary income and capital gains, but may also include qualified dividends or return of capital. The tax character of
distributions paid for the years ended December 31, 2018, 2017 and 2016 was as follows:

Ordinary income(1)
Qualified dividends
Distributions of long term capital gains
Distributions on tax basis

Main Street's taxable income for each period is an estimate and will not be finally determined until the company files
its tax return for each year. Therefore, the final taxable income, and the taxable income earned in each period and
carried forward for distribution in the following period, may be different than this estimate.

       The Taxable Subsidiaries primarily hold certain portfolio investments for Main Street. The Taxable Subsidiaries permit Main Street to
hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the
"source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with Main
Street for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in Main
Street's consolidated financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated
with MSCC for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their
ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or
loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at their normal
corporate tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the
Taxable Subsidiaries are reflected in Main Street's consolidated financial statements.

       The income tax expense, or benefit, and the related tax assets and liabilities generated by the Taxable Subsidiaries, if any, are reflected

       MSCC operates in a manner to maintain its RIC status and to eliminate corporate-level U.S. federal income tax (other than the 4%
excise tax) by distributing sufficient investment company taxable income and long-term capital gains. As a result, MSCC will have an
effective tax rate equal to 0% before the excise tax and income taxes incurred by the Taxable Subsidiaries. As such, a reconciliation of the
differences between Main Street's reported income tax expense and its tax expense at the federal statutory rate of 21% is not meaningful.

       As of December 31, 2018, the cost of investments for U.S. federal income tax purposes was $2,244.0 million, with such investments
having a gross unrealized appreciation of $385.6 million and gross unrealized depreciation of $172.0 million.

       The net deferred tax liability at December 31, 2018 was $17.0 million compared to $10.6 million at December 31, 2017, primarily
related to loss carryforwards, timing differences in net unrealized appreciation or depreciation and other temporary book-tax differences
relating to portfolio investments held by the Taxable Subsidiaries. The net deferred tax liability as of December 31, 2017 equal to
$10.6 million reflects a reduction of $2.8 million resulting from the decrease in the U.S. federal corporate income tax rate from 35% to 21%
as enacted by the Tax Cuts and Jobs Act (see further discussion in Note B.9.). For the year ended December 31, 2018, for U.S. federal
income tax purposes, the Taxable Subsidiaries had capital loss carryforwards totaling approximately $7.8 million which, if unused, will
expire in taxable year 2021 and generated a capital loss carryforward of $5.1 million which, if unused, will expire in taxable year 2023. At
December 31, 2018, for U.S. federal income tax purposes, the Taxable Subsidiaries had a net operating loss carryforward from prior years
which, if unused, will expire in various taxable years from 2028 through 2037. Under the Tax Cuts and Jobs Act, any net operating losses
generated in 2018 and future periods will have an indefinite carryforward. The timing and manner in which Main Street will utilize any loss
carryforwards generated before December 31, 2018 may be limited in the future under the provisions of the Code. Additionally, as a result
of the Tax Cuts and Jobs Act, our Taxable Subsidiaries have an interest expense limitation carryforward which have an indefinite
carryforward.

       Management believes that the realization of the deferred tax assets is more likely than not based on expectations as to future taxable
income and scheduled reversals of temporary differences. Accordingly, Main Street did not record a valuation allowance related to its
deferred tax assets at December 31, 2018 and

NOTE H — COMMON STOCK

       Main Street maintains a program with certain selling agents through which it can sell shares of its common stock by means of at-the-
market offerings from time to time (the "ATM Program"). During the year ended December 31, 2018, Main Street sold 2,060,019 shares of
its common stock at a weighted-average price of $38.48 per share and raised $79.3 million of gross proceeds under the ATM Program. Net
proceeds were $78.0 million after commissions to the selling agents on shares sold and offering costs. As of December 31, 2018, 2,994,469
shares remained available for sale under the ATM Program.

       During the year ended December 31, 2017, Main Street sold 3,944,972 shares of its common stock at a weighted-average price of
$38.72 per share and raised $152.8 million of gross proceeds under the ATM Program. Net proceeds were $150.9 million after
commissions to the selling agents on shares sold and offering costs.

       During the year ended December 31, 2016, Main Street sold 3,324,646 shares of its common stock at a weighted-average price of
$34.17 per share and raised $113.6 million of gross proceeds under the ATM Program. Net proceeds were $112.0 million after
commissions to the selling agents on shares sold and offering costs.

NOTE I — DIVIDEND REINVESTMENT PLAN ("DRIP")

       Main Street's DRIP provides for the reinvestment of dividends on behalf of its stockholders, unless a stockholder has elected to receive
dividends in cash. As a result, if Main Street declares a cash dividend, its stockholders who have not "opted out" of the DRIP by the
dividend record date will have their cash dividend automatically reinvested into additional shares of MSCC common stock. The share
requirements of the DRIP may be satisfied through the issuance of shares of common stock or through open market purchases of common
stock by the DRIP plan administrator. Newly issued shares will be valued based upon the final closing price of MSCC's common stock on
the valuation date determined for each dividend by Main Street's Board of Directors. Shares purchased in the open market to satisfy the
DRIP requirements will be valued based upon the average price of the applicable shares purchased, before any associated brokerage or
other

costs. Main Street's DRIP is administered by its transfer agent on behalf of Main Street's record holders and participating brokerage firms.
Brokerage firms and other financial intermediaries may decide not to participate in Main Street's DRIP but may provide a similar dividend
reinvestment plan for their clients.

       For the year ended December 31, 2018, $14.9 million of the total $170.9 million in dividends paid to stockholders represented DRIP
participation. During this period, the DRIP participation requirements were satisfied with the issuance of 394,403 newly issued shares. For
the year ended December 31, 2017, $9.2 million of the total $157.6 million in dividends paid to stockholders represented DRIP
participation. During this period, the DRIP participation requirements were satisfied with the issuance of 234,513 newly issued shares. For
the year ended December 31, 2016, $14.1 million of the total $141.6 million in dividends paid to stockholders represented DRIP
participation. During this period, the DRIP participation requirements were satisfied with the issuance of 434,631 newly issued shares. The
shares disclosed above relate only to Main Street's DRIP and exclude any activity related to broker-managed dividend reinvestment plans.

NOTE J — SHARE-BASED COMPENSATION

       Main Street accounts for its share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation —
Stock Compensation. Accordingly, for restricted stock awards, Main Street measured the grant date fair value based upon the market price
of its common stock on the date of the grant and amortizes the fair value of the awards as share-based compensation expense over the
requisite service period, which is generally the vesting term.

       Main Street's Board of Directors approves the issuance of shares of restricted stock to Main Street employees pursuant to the Main
Street Capital Corporation 2015 Equity and Incentive Plan (the "Equity and Incentive Plan"). These shares generally vest over a three-year
period from the grant date. The fair value is expensed over the service period, starting on the grant date. The following table summarizes
the restricted stock issuances approved by Main Street's Board of Directors under the Equity and Incentive Plan, net of shares forfeited, if
any, and the remaining shares of restricted stock available for issuance as of December 31, 2018.

the time they are made (which are typically through existing cash and cash equivalents and borrowings under the Credit Facility). Main
Street follows a process to manage its liquidity and ensure that it has available capital to fund its unfunded commitments as necessary. The
Company had total unrealized depreciation of $0.3 million on the outstanding unfunded commitments as of December 31, 2018.

       Main Street may, from time to time, be involved in litigation arising out of its operations in the normal course of business or otherwise.
Furthermore, third parties may try to impose liability on Main Street in connection with the activities of its portfolio companies. While the
outcome of any current legal proceedings cannot at this time be predicted with certainty, Main Street does not expect any current matters
will materially affect its financial condition or results of operations; however, there can be no assurance whether any pending legal
proceedings will have a material adverse effect on Main Street's financial condition or results of operations in any future reporting period.

NOTE M — RELATED PARTY TRANSACTIONS

       As discussed further in Note D, the External Investment Manager is treated as a wholly owned portfolio company of MSCC and is
included as part of Main Street's Investment Portfolio. At December 31, 2018, Main Street had a receivable of approximately $2.9 million
due from the External Investment Manager which included (i) approximately $1.8 million related primarily to operating expenses incurred
by MSCC or its subsidiaries as required to support the External Investment Manager's business and amounts due from the External
Investment Manager to Main Street under a tax sharing agreement (see further discussion in Note D) and (ii) approximately $1.2 million of
dividends declared but not paid by the External Investment Manager.

       In November 2015, Main Street's Board of Directors approved and adopted the Main Street Capital Corporation Deferred
Compensation Plan (the "2015 Deferred Compensation Plan"). The 2015 Deferred Compensation Plan became effective on January 1, 2016
and replaced the Deferred Compensation Plan for Non-Employee Directors previously adopted by the Board of Directors in June 2013 (the
"2013 Deferred Compensation Plan"). Under the 2015 Deferred Compensation Plan, non-employee directors and certain key employees
may defer receipt of some or all of their cash compensation and directors' fees, subject to certain limitations. Individuals participating in the
2015 Deferred Compensation Plan receive distributions of their respective balances based on predetermined payout schedules or other
events as defined by the plan and are also able to direct investments made on their behalf among investment alternatives permitted from
time to time under the plan, including phantom Main Street stock units. As of December 31, 2018, $6.1 million of compensation and
directors' fees had been deferred under the 2015 Deferred Compensation Plan (including amounts previously deferred under the 2013
Deferred Compensation Plan). Of this amount, $3.3 million was deferred into phantom Main Street stock units, representing 97,344 shares
of Main Street's common stock. Including phantom stock units issued through dividend reinvestment and net of any shares distributed, the
phantom stock units outstanding as of December 31, 2018 represented 119,639 shares of Main Street's common stock. Any amounts
deferred under the plan represented by phantom Main Street stock units will not be issued or included as outstanding on the consolidated
statements of changes in net assets until such shares are actually distributed to the participant in accordance with the plan, but are included
in operating expenses and weighted-average shares outstanding in Main Street's consolidated statements of operations as earned.

NOTE N — SUBSEQUENT EVENTS

       In January 2019, Main Street led a new portfolio investment to facilitate the minority recapitalization of Centre Technologies, Inc.

Centre's founder and Chief Executive Officer and management team to facilitate the transaction, with Main Street funding $18.1 million in
a combination of first-lien, senior secured term debt and a direct equity investment. Headquartered in Houston, Texas, and founded in 2006,
Centre has established itself as a mission critical IT solutions provider offering a full suite

of solutions including managed and hosted services, value-added sourcing and integration, and project services.

       In January 2019, Main Street led new portfolio investment to facilitate the management buyout of CompareNetworks Inc.
("CompareNetworks"), a leading provider of media, marketing and technology solutions that drive revenue for life science and healthcare
product manufacturers. Main Street, along with its co-investors, partnered with CompareNetworks' founders and management team to
facilitate the transaction, with Main Street funding $10.7 million in a combination of first-lien, senior secured term debt and a direct equity
investment. Headquartered in South San Francisco, California, and founded in 2000, CompareNetworks provides life scientists,
researchers, lab-based professionals, pharmaceutical professionals and healthcare professionals with digital tools and information resources
to research, identify and determine which products and technologies to use.

       In January 2019, Main Street fully exited its equity investment in Boss Industries, LLC ("Boss"). Boss markets, designs and
manufacturers vehicle-mounted, and portable air compressor and generator systems utilized in municipal and utility services, energy
product and industrial services. Main Street realized a gain of approximately $4.0 million on the exit of its equity investment in Boss.

       During February 2019, Main Street declared regular monthly dividends of $0.200 per share for each month of April, May and June
2019. These regular monthly dividends equal a total of $0.600 per share for the second quarter of 2019 and represent a 5.3% increase from
the dividends declared for the second quarter of 2018. Including the dividends declared for the second quarter of 2019, Main Street will
have paid $25.420 per share in cumulative dividends since its October 2007 initial public offering.

       5.    The registrant's other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over

       2.    Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact

       4.    The registrant's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures
(as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act
Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

       a)    Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under
our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known
to us by others within those entities, particularly during the period in which this report is being prepared;

       b)    Designed such internal control over financial reporting, or caused such internal control over financial reporting to be
designed under our supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with generally accepted accounting principles;

       c)    Evaluated the effectiveness of the registrant's disclosure controls and procedures and presented in this report our

registrant's most recent fiscal quarter (the registrant's fourth quarter in the case of an annual report) that has materially affected, or is
reasonably likely to materially affect, the registrant's internal control over financial reporting; and

       5.    The registrant's other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over
financial reporting, to the registrant's auditors and the audit committee of the registrant's Board of Directors (or persons performing the
equivalent functions):

       a)    All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting
which are reasonably likely to adversely affect the registrant's ability to record, process, summarize and report financial
information; and

       b)    Any fraud, whether or not material, that involves management or other employees who have a significant role in the
registrant's internal control over financial reporting.
