FORWARD-LOOKING
    STATEMENTS
  This Annual Report contains forward-looking statements which
    are subject to the safe harbor provisions of the Private
    Securities Litigation Reform Act of 1995. Statements that are
    not historical are forward-looking statements within the meaning
    of Section 27A of the Securities Act of 1933 and
    Section 21E of the Securities Exchange Act of 1934. Some of
    the statements in this Annual Report constitute forward-looking
    statements because they relate to future events or our future
    performance or financial condition. Forward-looking statements
    may include, among other things, statements as to our future
    operating results, our business prospects and the prospects of
    our portfolio companies, the impact of the investments that we
    expect to make, the ability of our portfolio companies to
    achieve their objectives, our expected financings and
    investments, the adequacy of our cash resources and working
    capital, and the timing of cash flows, if any, from the
    operations of our portfolio companies. Words such as
    expect, anticipate, target,
    goals, project, intend,
    plan, believe, seek,
    estimate, continue,
    forecast, may, should,
    potential, variations of such words, and similar
    expressions indicate a forward-looking statement, although not
    all forward-looking statements include these words. Readers are
    cautioned that the forward-looking statements contained in this
    Annual Report are only predictions, are not guarantees of future
    performance, and are subject to risks, events, uncertainties and
    assumptions that are difficult to predict. Our actual results
    could differ materially from those implied or expressed in the
    forward-looking statements for any reason, including the factors
    discussed in Item 1A entitled Risk Factors in
    Part I of this Annual Report and elsewhere in this Annual
    Report. Other factors that could cause actual results to differ
    materially include changes in the economy, risks associated with
    possible disruption in our operations or the economy generally
    due to terrorism, and future changes in laws or regulations and
    conditions in our operating areas. These statements are based on
    our current expectations, estimates, forecasts, information and
    projections about the industry in which we operate and the
    beliefs and assumptions of our management as of the date of this
    Annual Report. We assume no obligation to update or revise any
    forward-looking statements, whether as a result of new
    information, future events or otherwise, unless we are required
    to do so by law. Although we undertake no obligation to revise
    or update any forward-looking statements, whether as a result of
    new information, future events or otherwise, you are advised to
    consult any additional disclosures that we may make directly to
    you or through reports that we in the future may file with the
    SEC, including annual reports on

##### Table of Contents



Overview
    of our Business
        Our
    Business Strategy
    
    Focusing on Underserved Markets.  We believe
    that broad-based consolidation in the financial services
    industry coupled with operating margin and growth pressures have
    caused financial institutions to de-emphasize services to lower
    middle market companies in favor of larger corporate clients and
    capital market transactions. We believe these dynamics have
    resulted in the financing market for lower middle market
    companies to be underserved, providing us with greater
    investment opportunities.
    Providing Customized Financing Solutions.  We
    offer a variety of financing structures and have the flexibility
    to structure our investments to meet the needs of our portfolio
    companies. Typically we invest in senior and subordinated debt
    securities, coupled with equity interests. We believe our
    ability to customize financing arrangements makes us an
    attractive partner to lower middle market companies.
    Leveraging the Experience of Our Management
    Team.  Our senior management team has extensive
    experience advising, investing in, lending to and operating
    companies across changing market cycles. The members of our
    management team have diverse investment backgrounds, with prior
    experience at investment banks, specialty finance companies,
    commercial banks, and privately and publicly held companies in
    the capacity of executive officers. We believe this diverse
    experience provides us with an in depth understanding of the
    strategic, financial and operational challenges and
    opportunities of lower middle market companies. We believe this
    understanding allows us to select and structure better
    investments and to efficiently monitor and provide managerial
    assistance to our portfolio companies.
    Applying Rigorous Underwriting Policies and Active Portfolio
    Management.  Our senior management team has
    implemented rigorous underwriting policies that are followed in
    each transaction. These policies include a thorough analysis of
    each potential portfolio companys competitive position,
    financial performance, management team operating discipline,
    growth potential and industry 4

attractiveness, allowing us to better assess the companys
    prospects. After investing in a company, we monitor the
    investment closely, typically receiving monthly, quarterly and
    annual financial statements. We analyze and discuss in detail
    the companys financial performance with management in
    addition to attending regular board of directors meetings. We
    believe that our initial and ongoing portfolio review process
    allows us to monitor effectively the performance and prospects
    of our portfolio companies.  
    Taking Advantage of Low Cost Debentures Guaranteed by the
    SBA.  Our license to do business as an SBIC allows
    us to issue fixed-rate, low interest debentures which are
    guaranteed by the SBA and sold in the capital markets,
    potentially allowing us to increase our net interest income
    beyond the levels achievable by other BDCs utilizing traditional
    leverage.
    Maintaining Portfolio Diversification.  While
    we focus our investments in lower middle market companies, we
    seek to invest across various industries. We monitor our
    investment portfolio to ensure we have acceptable industry
    balance, using industry and market metrics as key indicators. By
    monitoring our investment portfolio for industry balance we seek
    to reduce the effects of economic downturns associated with any
    particular industry or market sector. However, we may from time
    to time hold securities of a single portfolio company that
    comprise more than 5.0% of our total assets
    and/or more
    than 10.0% of the outstanding voting securities of the portfolio
    company. For that reason, we are classified as a non-diversified
    management investment company under the 1940 Act.
    Utilizing Long-Standing Relationships to Source
    Deals.  Our senior management team maintains
    extensive relationships with entrepreneurs, financial sponsors,
    attorneys, accountants, investment bankers, commercial bankers
    and other non-bank providers of capital who refer prospective
    portfolio companies to us. These relationships historically have
    generated significant investment opportunities. We believe that
    our network of relationships will continue to produce attractive
    investment opportunities.  Investments

Equity
    Investments
    Investment
    Criteria
    
    Established Companies With Positive Cash
    Flow.  We seek to invest in established companies
    with a history of generating revenues and positive cash flows.
    We typically focus on companies with a history of profitability
    and minimum trailing twelve month EBITDA of $3.0 million.
    We do not invest in
    start-up
    companies, distressed situations,
    turn-aroundsituations or companies that we believe
    have unproven business plans.
    Experienced Management Teams With Meaningful Equity
    Ownership.  Based on our prior investment
    experience, we believe that a management team with significant
    experience with a portfolio company or relevant industry
    experience and meaningful equity ownership is more committed to
    a portfolio company. We believe management teams with these
    attributes are more likely to manage the companies in a manner
    that protects our debt investment and enhances the value of our
    equity investment.
    Strong Competitive Position.  We seek to invest
    in companies that have developed strong positions within their
    respective markets, are well positioned to capitalize on growth
    opportunities and compete in industries with barriers to entry.
    We also seek to invest in companies that exhibit a competitive
    advantage, which may help to protect their market position and
    profitability.
    Varied Customer and Supplier Base.  We prefer
    to invest in companies that have a varied customer and supplier
    base. Companies with a varied customer and supplier base are
    generally better able to endure economic downturns, industry
    consolidation and shifting customer preferences.
    Significant Invested Capital.  We believe the
    existence of significant underlying equity value provides
    important support to investments. We look for portfolio
    companies that we believe have sufficient value beyond the layer
    of the capital structure in which we invest.  Investment

    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%
    after each issuance of senior securities. If the value of our
    assets declines, we may be unable to satisfy this test. If that
    happens, we may be required to sell a portion of our investments
    and, depending on the nature of our leverage, repay a portion of
    our debt at a time when such sales
    and/or
    repayments may be disadvantageous.
    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.
    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,

We
    will be subject to corporate-level income tax if we are unable
    to qualify as a regulated investment company (RIC)
    under Subchapter M of the Code, which will adversely affect our
    results of operations and financial condition.
    
    The annual distribution requirement for a RIC will be satisfied
    if we distribute to our stockholders on an annual basis at least
    90.0% of our net ordinary 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 4.0% nondeductible
    federal excise tax, however, to the extent that we do not
    satisfy certain additional minimum distribution requirements on
    a calendar year basis. See Material U.S. Federal
    Income Tax Considerations. Because we use debt financing,
    we are subject to certain asset coverage ratio requirements
    under the 1940 Act 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 annual 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 income tax.
    The income source requirement will be satisfied if we obtain at
    least 90.0% of our 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 50.0% 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
    25.0% of the value of our assets can be invested in the
    securities, other than U.S. government securities or
    securities of other RICs, of one issuer, 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 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 will be in private companies, and therefore
    will be relatively illiquid, any such dispositions could be made
    at disadvantageous prices and could result in substantial losses.    We may
    not be able to pay you distributions, our distributions may not
    grow over time, and a portion of distributions paid to you may
    be a return of capital.

  The
    Fund, as an SBIC, may be unable to make distributions to us that
    may harm our ability to meet regulated investment company
    requirements, which could result in the imposition of an
    entity-level tax.
    Because
    we intend to distribute substantially all of our income to our
    stockholders to maintain our status as a regulated investment
    company, we will continue to need additional capital to finance
    our growth, and regulations governing our operation as a
    business development company will affect our ability to, and the
    way in which we, raise additional capital.

    We have a commitment to extend credit, in the form of loans and
    additional equity contributions, to two of our portfolio
    companies which are undrawn as of December 31, 2009. Since
    this commitment may expire without being drawn upon, the total
    commitment amount does not necessarily represent future cash
    requirements, however we have chosen to present the amount of
    this unused commitment as an obligation in this table.(2)
    
    We lease our corporate office facility under an operating lease
    that terminates on December 31, 2013. We believe that our
    existing facilities will be adequate to meet our needs at least
    through 2010, and that we will be able to obtain additional
    space when, where and as needed on acceptable terms.  Recent
