PRELIMINARY PROSPECTUS SUPPLEMENT

(To prospectus dated July 2, 2012)

$50,000,000

% Senior Notes due 2022

Triangle Capital Corporation is organized as an internally-managed, non-diversified closed-end management investment company that has elected to be treated as a business development company under the Investment Company Act of 1940. We are offering $50,000,000 in aggregate principal amount of % senior notes due 2022, which we refer to as the Notes. The Notes will mature on December 15, 2022. We will pay interest on the Notes on March 15, June 15, September 15 and December 15 of each year, beginning December 15, 2012. We may redeem the Notes in whole or in part at any time or from time to time on or after December 15, 2015, at the redemption price of par, plus accrued interest, as discussed under the caption “Specific Terms of the Notes and the Offering—Optional redemption” in this prospectus supplement. The Notes will be issued in minimum denominations of $25 and integral multiples of $25 in excess thereof.

We intend to list the Notes on the New York Stock Exchange and we expect trading to commence thereon within 30 days of the original issue date under the trading symbol “TCCA.” The Notes are expected to trade “flat.” This means that purchasers will not pay, and sellers will not receive, any accrued and unpaid interest on the Notes that is not included in the trading price.

| If we redeem only some of the Notes, the Trustee will determine the method for selection of the particular Notes to be redeemed, in accordance with the 1940 Act to the extent applicable and in accordance with the rules of any national securities exchange or quotation system on which the Notes are listed. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes called for redemption.

Covenant defeasance | The Notes are subject to covenant defeasance by us.

Form of Notes | The Notes will be represented by global securities that will be deposited and registered in the name of The Depository Trust Company, or DTC, or its nominee. This means that, except in limited circumstances, you will not receive certificates for the Notes. Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Notes through either DTC, if they are a participant, or indirectly through organizations that are participants in DTC.

Other covenants | In addition to any covenants described elsewhere in this prospectus supplement or the accompanying prospectus, the following covenants shall apply to the Notes:

| • |  | We agree that for the period of time during which the Notes are outstanding, we will not violate Section 18(a)(1) as modified by Section 61(a)(1) of the 1940 Act or any successor provisions, whether or not we continue to be subject to such provisions of the 1940 Act, but giving effect, in either case, to any exemptive relief granted to us by the SEC. These provisions generally prohibit us from (i) making additional borrowings, including through the

S-4

##### Table of Contents

| 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% after such borrowings, and (ii) declaring any cash dividend or distribution upon any class of our capital stock, or purchasing any such capital stock if our asset coverage, as defined in the 1940 Act, is below 200% at the time of the declaration of the dividend or distribution or the purchase and after deducting the amount of such dividend, distribution or purchase.

| • |  | If, at any time, we are not subject to the reporting requirements of Sections 13 or 15(d) of the Securities Exchange Act of 1934, or the Exchange Act, to file any periodic reports with the SEC, we agree to furnish to holders of the Notes and the Trustee, for the period of time during which the Notes are outstanding, our audited annual consolidated financial statements, within 90 days of our fiscal year end, and unaudited interim consolidated financial statements, within 45 days of our fiscal quarter end (other than our fourth fiscal quarter). All such financial statements will be prepared, in all material respects, in accordance with applicable United States generally accepted accounting principles, or U.S. GAAP.

Events of default | You will have rights if an Event of Default occurs with respect to the Notes and is not cured.

| The term “Event of Default” in respect of the Notes means any of the following:

| • |  | We do not pay the principal of any Note on its due date.

| • |  | We do not pay interest on any Note when due, and such default is not cured within 30 days.

| • |  | We remain in breach of any other covenant with respect to the Notes for 60 days after we receive a written notice of default stating we are in breach. The notice must be sent by either the Trustee or holders of at least 25% of the principal amount of the Notes.

| • |  | We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur and in the case of certain orders or decrees entered against us under any bankruptcy law, such order or decree remains undischarged or unstayed for a period of 60 days.

| • |  | On the last business day of each of twenty-four consecutive calendar months, the Notes have an asset coverage of less than 100%.

S-5

##### Table of Contents

Global Clearance and Settlement Procedures | Interests in the Notes will trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. None of the Company, the Trustee or the Paying Agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Use of proceeds | We estimate that the net proceeds we will receive from the sale of the $50.0 million aggregate principal amount of Notes in this offering will be approximately $ million (or approximately $ million if the underwriters fully exercise their over-allotment option), in each case assuming a public offering price of 100% of par, after deducting the underwriting discount of $ million (or approximately $ million if the underwriters fully exercise their over-allotment option) payable by us and estimated offering expenses of approximately $300,000 payable by us. We intend to use the net proceeds of this offering to invest in lower middle market companies in accordance with our investment objective and strategies and for working capital and general corporate purposes.

THE COMPANY

This summary highlights some of the information in this prospectus supplement and the accompanying prospectus. It is not complete and may not contain all of the information that you may want to consider. To understand the terms of the Notes offered hereby, you should read the entire prospectus supplement and the accompanying prospectus carefully. Together, these documents describe the specific terms of the securities we are offering. You should carefully read the sections titled “Risk Factors,” “Selected Consolidated Financial and Other Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Available Information” and the financial statements contained elsewhere in this prospectus supplement and the accompanying prospectus. Except as otherwise noted, all information in this prospectus supplement and the accompanying prospectus assumes no exercise of the underwriters’ over-allotment option.

Triangle Capital Corporation is a Maryland corporation incorporated on October 10, 2006, for the purpose of acquiring Triangle Mezzanine Fund LLLP, or Triangle SBIC, and its general partner, Triangle Mezzanine LLC, or TML, raising capital in its initial public offering, or IPO, which closed on February 21, 2007 and, thereafter, operating as an internally managed business development company, or BDC, under the 1940 Act. Triangle SBIC is licensed as a small business investment company, or SBIC, by the United States Small Business Administration, or SBA. Simultaneously with the consummation of our IPO, we acquired all of the equity interests in Triangle SBIC and TML as described in the accompanying prospectus under “Formation Transactions,” whereby Triangle SBIC became our wholly owned subsidiary. Triangle Mezzanine Fund II LP, or Triangle SBIC II, is a wholly owned subsidiary of Triangle Capital Corporation that is licensed by the SBA to operate as an SBIC. Unless otherwise noted in this prospectus supplement or the accompanying prospectus, the terms “we,” “us,” “our,” the “Company” and “Triangle” refer to Triangle SBIC prior to the IPO and to Triangle Capital Corporation and its subsidiaries, including Triangle SBIC and Triangle SBIC II, currently existing, and the term “SBIC subsidiaries” refers collectively to Triangle SBIC and Triangle SBIC II.

Triangle Capital Corporation

Triangle Capital Corporation is a specialty finance company that provides customized financing solutions to lower middle market companies located throughout the United States. Our goal is to be the premier provider of capital to these companies. Our investment objective is to seek attractive returns by generating current income from our debt investments and capital appreciation from our equity related investments. Our investment philosophy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in subordinated debt securities secured by second lien security interests in portfolio company assets, coupled with equity interests. On a more limited basis, we also invest in senior debt securities secured by first lien security interests in portfolio companies.

We focus on investments in companies with a history of generating revenues and positive cash flow, an established market position and a proven management team with a strong operating discipline. Our target portfolio company has annual revenues between $20.0 and $200.0 million and annual earnings before interest, taxes, depreciation and amortization, or EBITDA, between $3.0 and $20.0 million. We believe that these companies have less access to capital and that the market for such capital is underserved relative to larger companies. Companies of this size are generally privately held and are less well known to traditional capital sources such as commercial and investment banks.

Our investments generally range from $5.0 to $25.0 million per portfolio company. In certain situations, we have partnered with other funds to provide larger financing commitments. We are continuing to operate Triangle SBIC and Triangle SBIC II as SBICs and to utilize the proceeds of the sale of SBA guaranteed debentures, referred to herein as SBA leverage, to enhance returns to our stockholders. As of June 30, 2012, we had investments in 69 portfolio companies, with an aggregate cost of $590.9 million.

S-8

##### Table of Contents

As a BDC, we are generally required to meet a coverage ratio of total assets to total borrowings and other senior securities, which include all of our borrowings (other than SBA leverage) and any preferred stock we may issue in the future, of at least 200%.

Our principal executive offices are located at 3700 Glenwood Avenue, Suite 530, Raleigh, North Carolina 27612, and our telephone number is 919-719-4770. We maintain a website on the Internet at www.tcap.com. Information contained on our website is not incorporated by reference into this prospectus supplement or the accompanying prospectus, and you should not consider that information to be part of this prospectus supplement or the accompanying prospectus.

Our Business Strategy

We seek attractive returns by generating current income from our debt investments and capital appreciation from our equity related investments by:

| • |  | 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 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 opportunities associated with 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 attractiveness, which we believe allows 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 participating in 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. The licenses of Triangle SBIC and Triangle SBIC II to do business as SBICs allow them (subject to availability and continued regulatory compliance) 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

S-9

##### Table of Contents

| 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.

Our Investment Criteria

We utilize the following criteria and guidelines in evaluating investment opportunities. However, not all of these criteria and guidelines have been, or will be, met in connection with each of our investments.

| • |  | 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 generally 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.

Recent Developments

Expansion of Credit Facility

In September 2012, we entered into a four-year senior secured credit facility with an initial commitment of $165.0 million. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and replaces the Company’s existing $75.0 million senior secured credit facility. The Credit Facility has an accordion feature which allows for an increase in the total loan size up to $215.0 million and also contains two one-year extension options bringing the total potential term to six years from closing. Borrowings under the Credit Facility will generally bear interest at a rate of LIBOR plus 2.95%.

Proposed BDC Legislation

On June 8, 2012, legislation was introduced in the U.S. House of Representatives intended to revise certain regulations applicable to BDCs. The legislation provides for (i) increasing the amount of funds BDCs may

##### Table of Contents

borrow by reducing asset to debt limitations from 2:1 to 3:2, (ii) permitting BDCs to file registration statements with the U.S. Securities and Exchange Commission that incorporate information from already-filed reports by reference, (iii) utilizing other streamlined registration processes afforded to operating companies, and (iv) allowing BDCs to own investment adviser subsidiaries.

There are no assurances as to when the legislation will be enacted by Congress, if at all, or, if enacted, what final form the legislation would take.

RISK FACTORS

The Notes will be unsecured and therefore will be effectively subordinated to any secured indebtedness we have currently incurred or may incur in the future.

The Notes will not be secured by any of our assets or any of the assets of our subsidiaries and will rank equally in right of payment with all of our existing and future unsubordinated, unsecured senior indebtedness, including without limitation, the $69.0 million aggregate principal amount of the 2019 Notes. 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 September 30, 2012 we had $26.0 million outstanding under the Credit Facility. The indebtedness under the Credit Facility is effectively senior to the Notes to the extent of the value of the assets securing such indebtedness.

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

The Notes are obligations exclusively of Triangle 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. A significant portion of the indebtedness required to be consolidated on our balance sheet is held through our SBIC subsidiaries. For example, as of June 30, 2012, Triangle SBIC had issued $139.6 million of SBA-guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval and Triangle SBIC II had issued the statutory maximum of $75.0 million of SBA-guaranteed debentures. The assets of such subsidiaries are not directly available to satisfy the claims of our creditors, including holders of the Notes. See “The Company — Recent Developments” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Financial Condition, Liquidity and Capital Resources — Financing Transactions” in this prospectus supplement 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 creditors of our subsidiaries will 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 will be 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 indenture under which the Notes will be issued contains limited protection for holders of the Notes.

The indenture under which the Notes will be issued offers limited protection to holders of the Notes. The terms of the indenture 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 your investment in the Notes. In particular, the terms of the indenture and the Notes will 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

S-13

##### Table of Contents

| 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) as modified by Section 61(a)(1) of the 1940 Act or any successor provisions, whether or not we continue to be subject to such provisions of the 1940 Act, but giving effect, in either case, to any exemptive relief granted to us by the SEC (these provisions generally prohibit us from (i) 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% after such borrowings, and (ii) declaring any cash dividend or distribution upon any class of our capital stock, or purchasing any such capital stock if our asset coverage, as defined in the 1940 Act, is below 200% at the time of the declaration of the dividend or distribution or the purchase and after deducting the amount of such dividend, distribution or purchase);

| • |  | 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.

In addition, the indenture will not require us to offer to purchase the Notes in connection with a change of control or any other event.

Furthermore, the terms of the indenture 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, 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 other than as described under “Specific Terms of the Notes and the Offering—Events of default.”

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 indenture and the Notes, including additional covenants and events of default. For example, the indenture under which the Notes will be issued does 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.

An active trading market for the Notes may not develop, which could limit the market price of the Notes or your ability to sell them.

The Notes are a new issue of debt securities for which there currently is no trading market. We intend to list the Notes on the NYSE within 30 days of the original issue date under the symbol “TCCA.” Although we expect the Notes to be listed on the NYSE, we cannot provide any assurances that an active trading market will develop or be maintained for the Notes or that you will be able to sell your Notes. If the Notes are traded after their initial issuance, they may trade at a discount from their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, general economic conditions, our financial condition, performance and prospects and other factors. The underwriters have advised us that they intend to make a market in the Notes, but they are not obligated to do so. The underwriters may discontinue any market-making in the Notes at any time at their sole discretion. Accordingly, we cannot assure you that a liquid trading market will

S-14

##### Table of Contents

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, 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.

We may choose to redeem the Notes when prevailing interest rates are relatively low.

On or after December 15, 2015, we may choose to redeem the Notes from time to time, especially when prevailing interest rates are lower than the rate borne by the Notes. If prevailing rates are lower at the time of redemption, you would not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the Notes being redeemed. Our redemption right also may adversely impact your ability to sell the Notes as the optional redemption date or period approaches.

Our amount of debt outstanding will increase as a result of this offering, and if we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Notes.

As of September 30, 2012, we had approximately $278.6 million of indebtedness, including $26.0 million outstanding under the Credit Facility, $69.0 million outstanding from the 2019 Notes and $183.6 million outstanding from SBA-guaranteed debentures. Any default under the agreements governing our indebtedness, including a default under the Credit Facility or other indebtedness to which we may be a party that is not waived by the required lenders, 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 (including the Credit Facility), 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 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 any Notes sold, 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 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 or other debt and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under the Credit Facility or other debt, the lenders 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.

Pending legislation may allow us to incur additional leverage.

As a BDC, under the 1940 Act generally we are not permitted to incur indebtedness unless immediately after such borrowing we have an asset coverage for total borrowings of at least 200% (i.e., the amount of debt

S-15

##### Table of Contents

may not exceed 50% of the value of our assets). Recent legislation introduced in the U.S. House of Representatives, if passed, would modify this section of the 1940 Act and increase the amount of debt that business development companies may incur by modifying the percentage from 200% to 150%. See “The Company — Recent Developments — Proposed BDC Legislation” for more information with respect to this legislation. As a result, we may be able to incur additional indebtedness in the future and therefore your risk of an investment in the Notes may increase.

We will be subject to corporate-level U.S. federal income tax if we are unable to maintain our status as a regulated investment company under Subchapter M of the Code, which will adversely affect our results of operations and financial condition.

We have elected to be treated as a RIC under the Code, which generally will allow us to avoid being subject to corporate-level U.S. federal income tax. To obtain and 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 90.0% of our net ordinary income and net short-term capital gain in excess of net long-term capital loss, if any. We will be subject to a 4.0% nondeductible U.S. federal excise tax, however, to the extent that we do not satisfy certain additional minimum distribution requirements on a calendar year basis. 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 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 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 illiquid, any such dispositions could be made at disadvantageous prices and could result in substantial losses.

If we fail to qualify for or maintain RIC tax treatment for any reason and are subject to corporate-level U.S. federal 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 also be subject to certain U.S. federal excise taxes, as well as state, local and foreign taxes. In addition, we could become subject to corporate-level U.S. federal income in the future if Congress decides to alter or eliminate the pass-through tax treatment applicable to RICs under the Code.

USE OF PROCEEDS

We estimate that the net proceeds we will receive from the sale of the $50.0 million aggregate principal amount of Notes in this offering will be approximately $ million (or approximately $ million if the underwriters fully exercise their over-allotment option), in each case assuming a public offering price of 100% of par, after deducting the underwriting discount of $ million (or approximately $ million if the underwriters fully exercise their over-allotment option) payable by us and estimated offering expenses of approximately $300,000 payable by us.

We intend to use the net proceeds of this offering to invest in lower middle market companies in accordance with our investment objective and strategies and for working capital and general corporate purposes. Pending such use, we will invest the net proceeds of this offering primarily in short-term securities consistent with our BDC election and our election to be taxed as a regulated investment company, or RIC.

Overview of Our Business

We are a Maryland corporation which has elected to be treated and operates as an internally managed business development company, or BDC, under the Investment Company Act of 1940, or 1940 Act. Our wholly-owned subsidiaries, Triangle Mezzanine Fund LLLP, or Triangle SBIC, and Triangle Mezzanine Fund II LP, or Triangle SBIC II, are licensed as small business investment companies, or SBICs, by the United States Small Business Administration, or SBA. In addition, Triangle SBIC has also elected to be treated as a BDC under the 1940 Act. We, Triangle SBIC and Triangle SBIC II invest primarily in debt instruments, equity investments, warrants and other securities of lower middle market privately held companies located in the United States.

Our business is to provide capital to lower middle market companies in the United States. We focus on investments in companies with a history of generating revenues and positive cash flows, an established market position and a proven management team with a strong operating discipline. Our target portfolio company has annual revenues between $20.0 million and $200.0 million and annual earnings before interest, taxes, depreciation and amortization, or EBITDA, between $3.0 million and $20.0 million.

We invest primarily in subordinated debt securities secured by second lien security interests in portfolio company assets, coupled with equity interests. On a more limited basis, we also invest in senior debt securities secured by first lien security interests in portfolio companies. Our investments generally range from $5.0 million to $25.0 million per portfolio company. In certain situations, we have partnered with other funds to provide larger financing commitments.

We generate revenues in the form of interest income, primarily from our investments in debt securities, loan origination and other fees and dividend income. Loan origination fees received in connection with our debt investments are recognized as investment income over the life of the loan using the effective interest method or, in some cases, recognized as earned. We also receive fees from our portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received. In addition, we generate revenue in the form of capital gains, if any, on warrants or other equity-related securities that we acquire from our portfolio companies. Our debt investments generally have a term of between three and seven years and typically bear interest at fixed rates between 12.0% and 17.0% per annum. Certain of our debt investments have a form of interest, referred to as payment in kind, or PIK, interest, that is not paid currently but is instead accrued and added to the loan balance and paid at the end of the term. In our negotiations with potential portfolio

S-22

##### Table of Contents

companies, we generally seek to minimize PIK interest. Cash interest on our debt investments is generally payable monthly; however, some of our debt investments pay cash interest on a quarterly basis. As of both June 30, 2012 and December 31, 2011, the weighted average yield on our outstanding debt investments other than non-accrual debt investments (including PIK interest) was approximately 15.0%. The weighted average yield on all of our outstanding investments (including equity and equity-linked investments but excluding non-accrual debt investments) was approximately 13.8% and 13.9% as of June 30, 2012 and December 31, 2011, respectively. The weighted average yield on all of our outstanding investments (including equity and equity-linked investments and non-accrual debt investments) was approximately 13.6% as of both June 30, 2012 and December 31, 2011.

Triangle SBIC and Triangle SBIC II are eligible to issue debentures to the SBA, which pools these with debentures of other SBICs and sells them in the capital markets at favorable interest rates, in part as a result of the guarantee of payment from the SBA. Triangle SBIC and Triangle SBIC II invest these funds in portfolio companies. We intend to continue to operate Triangle SBIC and Triangle SBIC II as SBICs, subject to SBA approval, and to utilize the proceeds from the issuance of SBA-guaranteed debentures, referred to herein as SBA leverage, to enhance returns to our stockholders.

Non-Accrual Assets

Generally, when interest and/or principal payments on a loan become past due, or if we otherwise do not expect the borrower to be able to service its debt and other obligations, we will place the loan on non-accrual status and will generally cease recognizing interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. As of December 31, 2011, the fair value of our non-accrual assets was approximately $7.6 million, which comprised 1.5% of the total fair value of our portfolio, and the cost of our non-accrual assets was approximately $11.0 million, which comprised 2.2% of the total cost of our portfolio. As of June 30, 2012, the fair value of our non-accrual assets was approximately $2.9 million, which comprised 0.5% of the total fair value of our portfolio, and the cost of our non-accrual assets was approximately $9.4 million, which comprised 1.6% of the total cost of our portfolio.

Our non-accrual assets as of June 30, 2012 are as follows:

Gerli and Company

In November 2008, we placed our debt investment in Gerli and Company, or Gerli, on non-accrual status. As a result, under U.S. GAAP, we no longer recognize interest income on our debt investment in Gerli for financial reporting purposes. During the first quarter of 2011, we restructured our investment in Gerli. As a result of the restructuring, we received a new note from Gerli with a face amount of $3.0 million and a fair value of approximately $2.3 million and preferred stock with a liquidation preference of $0.4 million. In addition, in the second quarter of 2012, we invested $250,000 in a Gerli senior subordinated note. Under the terms of the notes, interest on the notes is payable only if Gerli meets certain covenants, which they were not compliant with as of June 30, 2012. In the six months ended June 30, 2012, we recognized unrealized depreciation on our debt investments in Gerli of approximately $0.4 million. As of June 30, 2012, the cost of our debt investments in Gerli was $3.3 million and the fair value was $1.8 million.

Fire Sprinkler Systems, Inc.

In October 2008, we placed our debt investment in Fire Sprinkler Systems, Inc., or Fire Sprinkler Systems, on non-accrual status. As a result, under U.S. GAAP, we no longer recognize interest income on our debt investment in Fire Sprinkler Systems for financial reporting purposes. In the six months ended, June 30, 2012, we recorded unrealized depreciation of $0.5 million on our debt investment in Fire Sprinkler Systems. As of June 30, 2012, the cost of our debt investment in Fire Sprinkler Systems was $3.0 million and the fair value of such investment was $0.1 million.

Equisales, LLC

In May 2012, we placed our debt investment in Equisales, LLC, or Equisales, on non-accrual status. As a result, under U.S. GAAP, we no longer recognize interest income on our debt investment in Equisales for financial reporting purposes. In the six months ended, June 30, 2012, we recorded unrealized depreciation of $2.1 million on our debt investment in Equisales. As of June 30, 2012, the cost of our debt investment in Equisales was $3.2 million and the fair value of such investment was $1.0 million.

In addition to our non-accrual assets, as of June 30, 2012, we had, on a fair value basis, approximately $20.1 million of debt investments, or 3.4% of the total fair value of our portfolio, which were current with respect to scheduled principal and interest payments, but which were carried at less than cost. The cost of these assets as of June 30, 2012 was approximately $28.5 million, or 4.8% of the total cost of our portfolio. Included in these amounts as of June 30, 2012 are two assets (our subordinated notes to Home Physicians, LLC and Home Physicians Holdings, LP) that are on non-accrual only with respect to the PIK interest component of the loan.

Results of Operations

Comparison of three months ended June 30, 2012 and June 30, 2011

Investment Income

For the three months ended June 30, 2012, total investment income was $22.0 million, a 34% increase from $16.4 million of total investment income for the three months ended June 30, 2011. This increase was primarily attributable to an increase in total loan interest income (including PIK interest income) due to a net increase in our portfolio investments from June 30, 2011, to June 30, 2012, partially offset by a decrease in non-recurring fee income of approximately $1.2 million. Non-recurring fee income was approximately $1.0 million for the three months ended June 30, 2012 as compared to $2.2 million for the three months ended June 30, 2011.

Expenses

For the three months ended June 30, 2012, expenses increased by 28% to $7.9 million from $6.2 million for the three months ended June 30, 2011. The increase in expenses was attributable to a $1.4 million increase in interest and other financing fees and a $0.3 million increase in general and administrative expenses. The increase in interest and other financing fees is primarily related to interest on our 7.00% Notes due 2019, or 2019 Notes, of approximately $1.2 million in the quarter ended June 30, 2012. The increase in general and administrative expenses in the quarter ended June 30, 2012 was primarily related to increased salary and incentive compensation costs, as well as increased non-cash compensation expenses.

Net Investment Income

As a result of the $5.5 million increase in total investment income and the $1.7 million increase in expenses, net investment income increased by 37% to $14.1 million for the three months ended June 30, 2012 as compared to net investment income of $10.2 million for the three months ended June 30, 2011.

Net Increase/Decrease in Net Assets Resulting from Operations

In the three months ended June 30, 2012 we realized a gain on the sale of one control investment of approximately $0.8 million, gains on the sales of two non-control/non-affiliate investments totaling approximately $2.6 million and a gain on the repayment of one non-control/non-affiliate investment totaling approximately $0.2 million. In addition, during the three months ended June 30, 2012, we recorded net unrealized depreciation of investments totaling approximately $2.0 million, comprised of unrealized appreciation on 30 investments totaling approximately $7.8 million, unrealized depreciation on 18 investments totaling approximately $6.8 million and unrealized depreciation reclassification adjustments related to the realized gains noted above totaling $3.0 million.

In the three months ended June 30, 2011, we realized a gain on the sale of one control investment of approximately $12.2 million, a loss on the disposal of one control investment of $0.1 million, and gains on the repayments of two non-control/non-affiliate investments totaling approximately $0.8 million. In addition, during the three months ended June 30, 2011, we recorded net unrealized depreciation of investments totaling approximately $8.7 million, comprised of unrealized appreciation on 20 investments totaling approximately $4.7 million, unrealized depreciation on 13 investments totaling approximately $2.2 million and unrealized depreciation reclassification adjustments related to the realized gains noted above totaling $11.1 million.

As a result of these events, our net increase in net assets from operations was $15.6 million for the three months ended June 30, 2012 as compared to a net increase in net assets from operations of $14.5 million for the three months ended June 30, 2011.

Comparison of six months ended June 30, 2012 and June 30, 2011

Investment Income

For the six months ended June 30, 2012, total investment income was $41.1 million, a 42% increase from $28.8 million of total investment income for the six months ended June 30, 2011. This increase was primarily attributable to an increase in total loan interest income (including PIK interest income) due to a net increase in our portfolio investments from June 30, 2011, to June 30, 2012, partially offset by a decrease in non-recurring fee income of approximately $1.3 million. Non-recurring fee income was approximately $1.4 million for the six months ended June 30, 2012 as compared to $2.7 million for the six months ended June 30, 2011.

Expenses

For the six months ended June 30, 2012, expenses increased by 38% to $14.8 million from $10.7 million for the six months ended June 30, 2011. The increase in expenses was attributable to a $2.6 million increase in interest and other financing fees and a $1.5 million increase in general and administrative expenses. The increase in interest and credit facility fees is related to (i) interest on our 7.00% Senior Notes due 2019, or 2019 Notes, of approximately $1.6 million for the six months ended June 30, 2012, (ii) credit facility fees of approximately $0.2 million for the six months ended June 30, 2012, (iii) increased amortization of deferred financing fees related to costs associated with the 2019 Notes and (iv) higher weighted-average rates on outstanding SBA-guaranteed debentures for the six months ended June 30, 2012 as compared to weighted-average rates on outstanding SBA-guaranteed debentures for the six months ended June 30, 2011. The increase in general and administrative expenses for the six months ended June 30, 2012 was primarily related to increased salary and incentive compensation costs, as well as increased non-cash compensation expenses.

Net Investment Income

As a result of the $12.2 million increase in total investment income and the $4.1 million increase in expenses, net investment income increased by 45% to $26.2 million for the six months ended June 30, 2012 as compared to net investment income of $18.1 million for the six months ended June 30, 2011.

Net Increase/Decrease in Net Assets Resulting from Operations

In the six months ended June 30, 2012 we realized, a gain on the sale of one control investment of approximately $0.8 million, gains on the sales of two non-control/non-affiliate investments totaling approximately $2.6 million and a gain on the repayment of one non-control/non-affiliate investment totaling approximately $0.2 million. In addition, during the six months ended June 30, 2012, we recorded net unrealized depreciation of investments totaling approximately $1.4 million, comprised of 1) unrealized appreciation on 32 investments totaling approximately $12.2 million and 2) unrealized depreciation on 18 investments totaling approximately $10.6 million and 3) unrealized depreciation reclassification adjustments related to the realized gains noted above totaling $3.0 million.

In the six months ended June 30, 2011, we realized a gain on the sale of one control investment of approximately $12.2 million, a loss on the disposal of one control investment of $0.1 million, and gains on the repayments of two non-control/non-affiliate investments totaling approximately $0.8 million. In addition, during the six months ended June 30, 2011, we recorded net unrealized depreciation of investments totaling approximately $4.1 million, comprised of 1) unrealized appreciation on 21 investments totaling approximately $11.0 million, 2) unrealized depreciation on 17 investments totaling approximately $3.9 million and 3) an $11.1 million unrealized depreciation reclassification adjustment related to the realized gains noted above.

During both the six months ended June 30, 2012 and 2011, we recognized losses on extinguishment of debt of approximately $0.2 million related to prepayments of SBA-guaranteed debentures.

As a result of these events, our net increase in net assets from operations was $28.2 million for the six months ended June 30, 2012 as compared to a net increase in net assets from operations of $26.9 million for the six months ended June 30, 2011.

Liquidity and Capital Resources

We believe that our current cash and cash equivalents on hand, our available leverage under our line of credit and our anticipated cash flows from operations will be adequate to meet our cash needs for our daily operations for at least the next twelve months.

In the future, depending on the valuation of Triangle SBIC’s assets and Triangle SBIC II’s assets pursuant to SBA guidelines, Triangle SBIC and Triangle SBIC II may be limited by provisions of the Small Business Investment Act of 1958, and SBA regulations governing SBICs, from making certain distributions to Triangle Capital Corporation that may be necessary to enable Triangle Capital Corporation to make the minimum required distributions to its stockholders and qualify as a RIC.

Cash Flows

For the six months ended June 30, 2012, we experienced a net increase in cash and cash equivalents in the amount of $26.9 million. During that period, our operating activities used $65.6 million in cash, consisting primarily of new portfolio investments of $156.6 million, partially offset by repayments received from portfolio companies of approximately $71.4 million. In addition, financing activities provided $92.5 million of cash, consisting primarily of proceeds from a public common stock offering of $77.1 million and net proceeds from a public offering of 2019 Notes of $66.7 million, partially offset by cash dividends paid in the amount of $24.8 million, repayments of SBA-guaranteed debentures of $10.4 million, and a repayment of borrowings under the Credit Facility of $15.0 million. At June 30, 2012, we had $93.7 million of cash and cash equivalents on hand.

For the six months ended June 30, 2011, we experienced a net increase in cash and cash equivalents in the amount of $13.4 million. During that period, our operating activities used $55.4 million in cash, consisting primarily of new portfolio investments of $136.3 million, partially offset by repayments received from portfolio companies and proceeds from the sale of investments totaling $61.5 million. In addition, financing activities

provided $68.9 million of cash, consisting primarily of proceeds from a public common stock offering of $63.0 million, borrowings under SBA-guaranteed debentures payable of $31.1 million, offset by cash dividends paid in the amount of $13.8 million, repayments of SBA-guaranteed debentures of $9.5 million and financing fees paid in the amount of $1.2 million. At June 30, 2011, we had $68.2 million of cash and cash equivalents on hand.

Financing Transactions

Due to Triangle SBIC’s and Triangle SBIC II’s status as licensed SBICs, Triangle SBIC and Triangle SBIC II have the ability to issue debentures guaranteed by the SBA at favorable interest rates. Under the Small Business Investment Act and the SBA rules applicable to SBICs, an SBIC (or group of SBICs under common control) can have outstanding at any time debentures guaranteed by the SBA up to two times (and in certain cases, up to three times) the amount of its regulatory capital, which generally is the amount raised from private investors. As of June 30, 2012, the maximum statutory limit on the dollar amount of outstanding debentures guaranteed by the SBA issued by a single SBIC is $150.0 million and by a group of SBICs under common control is $225.0 million. Debentures guaranteed by the SBA have a maturity of ten years, with interest payable semi-annually. The principal amount of the debentures is not required to be paid before maturity but may be pre-paid at any time, without penalty.

As of June 30, 2012, Triangle SBIC has issued $139.6 million of SBA-guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of June 30, 2012, Triangle SBIC II has issued $75.0 million in face amount of SBA-guaranteed debentures. In addition to the one-time 1.0% fee on the total commitment from the SBA, the Company also pays a one-time 2.425% fee on the amount of each debenture issued (2.0% for SBA LMI debentures). These fees are capitalized as deferred financing costs and are amortized over the term of the debt agreements using the effective interest method. The weighted average interest rate for all SBA-guaranteed debentures as of June 30, 2012 was 4.76%.

In May 2011, we entered into a three-year senior secured credit facility (the “Credit Facility”) with an initial commitment of $50.0 million. In November 2011, we closed an expansion of the Credit Facility from $50.0 million to $75.0 million, which included the addition of one new lender. The purpose of the Credit Facility is to provide additional liquidity in support of future investment and operational activities. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and has an accordion feature which allows for an increase in the total loan size up to $90.0 million and also contains two one-year extension options, bringing the total potential commitment and funding period to five years from the closing date. The Credit Facility, which is structured to operate like a revolving credit facility, is secured primarily by Triangle Capital Corporation’s assets, excluding the assets of Triangle SBIC and Triangle SBIC II.

Borrowings under the Credit Facility bear interest, subject to our election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or (ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of (i) prime rate, (ii) the federal funds rate plus 0.5% or (iii) the adjusted one-month LIBOR plus 2.0%. We pay unused commitment fees of 0.375% per annum, which are included in “Interest and credit facility fees” on our Consolidated Statement of Operations. As of June 30, 2012, the Company had no borrowings outstanding under the Credit Facility.

In March 2012, we issued $69.0 million of the 2019 Notes. The 2019 Notes mature on March 15, 2019, and may be redeemed in whole or in part at any time or from time to time at our option on or after March 15, 2015. The 2019 Notes bear interest at a rate of 7.00% per year payable quarterly on March 15, June 15, September 15 and December 15 of each year, beginning June 15, 2012. The net proceeds from the sale of the 2019 Notes, after underwriting discounts and offering expenses, were approximately $66.7 million.

Distributions to Stockholders

We have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code, and intend to make the required distributions to our stockholders as specified therein. In

S-29

##### Table of Contents

order to qualify as a RIC and to obtain RIC tax benefits, we must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then we are generally required to pay income taxes only on the portion of our taxable income and gains we do not distribute (actually or constructively) and certain built-in gains. We have historically met our minimum distribution requirements and continually monitor our distribution requirements with the goal of ensuring compliance with the Code.

The minimum distribution requirements applicable to RICs require us to distribute to our stockholders each year at least 90% of our investment company taxable income, or ICTI, as defined by the Code. Depending on the level of ICTI earned in a tax year, we may choose to carry forward ICTI in excess of current year distributions into the next tax year and pay a 4% excise tax on such excess. Any such carryover ICTI must be distributed before the end of the next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI.

ICTI generally differs from net investment income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. We may be required to recognize ICTI in certain 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), we must include in ICTI 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 ICTI other amounts that we have not yet received in cash, such as (i) PIK interest income and (ii) interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. Because any original issue discount or other amounts accrued will be included in our ICTI for the year of accrual, we may be required to make a distribution to our stockholders in order to satisfy the minimum distribution requirements, even though we will not have received and may not ever receive any corresponding cash amount. ICTI also excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

Current Market Conditions

Beginning in 2008, the debt and equity capital markets in the United States were severely impacted by significant write-offs in the financial services sector relating to subprime mortgages and the re-pricing of credit risk in the broadly syndicated bank loan market, among other factors. These events, along with the deterioration of the housing market, led to an economic recession in the U.S. and abroad. Banks, investment companies and others in the financial services industry reported significant write-downs in the fair value of their assets, which led to the failure of a number of banks and investment companies, a number of distressed mergers and acquisitions, the government take-over of the nation’s two largest government-sponsored mortgage companies, the passage of the $700 billion Emergency Economic Stabilization Act of 2008 in October 2008 and the passage of the American Recovery and Reinvestment Act of 2009, or the Stimulus Bill, in February 2009. These events significantly impacted the financial and credit markets and reduced the availability of debt and equity capital for the market as a whole, and for financial firms in particular. Notwithstanding recent gains across both the equity and debt markets, the market continues to remain volatile due to the uncertainty surrounding the United States’ rapidly increasing national debt, European economic conditions, the automatic federal spending reductions, expiration of tax cuts at year-end and continuing global economic malaise, causing these conditions to possibly reoccur in the future and continue for a prolonged period of time. Although we have been able to secure access to additional liquidity, including our recent public offerings of common stock and debt securities, increased leverage available through the SBIC program as a result of the Stimulus Bill and the $75.0 million Credit Facility, there is no assurance that debt or equity capital will be available to us in the future on favorable terms, or at all.

Recent Developments

Expansion of Credit Facility

In September 2012, we entered into a four-year senior secured credit facility with an initial commitment of $165.0 million. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and replaces the Company’s existing $75.0 million senior secured credit facility. The Credit Facility has an accordion feature which allows for an increase in the total loan size up to $215.0 million and also contains two one-year extension options bringing the total potential term to six years from closing. Borrowings under the Credit Facility will generally bear interest at a rate of LIBOR plus 2.95%.

Critical Accounting Policies and Use of Estimates

The preparation of our unaudited financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the periods covered by such financial statements. We have identified investment valuation and revenue recognition as our most critical accounting estimates. On an on-going basis, we evaluate our estimates, including those related to the matters described below. These estimates are based on the information that is currently available to us and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates under different assumptions or conditions. A discussion of our critical accounting policies follows.

Investment Valuation

The most significant estimate inherent in the preparation of our financial statements is the valuation of investments and the related amounts of unrealized appreciation and depreciation of investments recorded. We have established and documented processes and methodologies for determining the fair values of portfolio company investments on a recurring basis in accordance with the 1940 Act and FASB ASC Topic 820, Fair Value Measurements and Disclosures, or ASC Topic 820. Under ASC Topic 820, a financial instrument is categorized within the ASC Topic 820 valuation hierarchy based upon the lowest level of input to the valuation process that is significant to the fair value measurement. The three levels of valuation inputs established by ASC Topic 820 are as follows:

Level 1 Inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 Inputs — include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 Inputs — include inputs that are unobservable and significant to the fair value measurement.

Our investment portfolio is comprised of debt and equity instruments of privately held companies for which quoted prices or other inputs falling within the categories of Level 1 and Level 2 are not available. Therefore, we determine the fair value of our investments in good faith using level 3 inputs, pursuant to a valuation policy and process that is established by our management with the assistance of certain third-party advisors and subsequently approved by our Board of Directors. There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. The recorded fair values of our investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned.

Our valuation process is led by our executive officers and managing directors. The valuation process begins with a quarterly review of each investment in our investment portfolio by our executive officers and our investment committee. Valuations of each portfolio security are then prepared by our investment professionals, who have direct responsibility for the origination, management and monitoring of each investment. Under our valuation policy, each investment valuation is subject to (i) a review by the lead investment officer responsible for the portfolio company investment and (ii) a peer review by a second investment officer or executive officer. Generally, any investment that is valued below cost is subjected to review by one of our executive officers. After

S-32

##### Table of Contents

the peer review is complete, we engage two independent valuation firms, Duff & Phelps, LLC and Lincoln Partners Advisors LLC (collectively, the “Valuation Firms”), to provide third-party reviews of certain investments, as described further below. In addition, all investment valuations are provided to our independent registered public accounting firm in connection with quarterly review procedures and the annual audit of our financial statements. Finally, the Board of Directors has the responsibility for reviewing and approving, in good faith, the fair value of our investments in accordance with the 1940 Act.

The Valuation Firms provide third party valuation consulting services to us which consist of certain limited procedures that we identified and requested the Valuation Firms to perform (hereinafter referred to as the “Procedures”). The Procedures are performed with respect to each portfolio company at least once in every calendar year and for new portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In addition, the Procedures are generally performed with respect to a portfolio company when there has been a significant change in the fair value of the investment. In certain instances, we may determine that it is not cost-effective, and as a result is not in our stockholders’ best interest, to request the Valuation Firms to perform the Procedures on one or more portfolio companies. Such instances include, but are not limited to, situations where the fair value of the investment in the portfolio company is determined to be insignificant relative to the total investment portfolio.

The total number of investments and the percentage of our portfolio on which the Procedures were performed are summarized below by period:

For the quarter ended: |  | Total companies |  |  | Percent of total investments at fair value(1) |

Upon completion of the Procedures, the Valuation Firms concluded that, with respect to each investment reviewed by each Valuation Firm, the fair value of those investments subjected to the Procedures appeared reasonable. Our Board of Directors is ultimately responsible for determining the fair value of our investments in good faith.

Investment Valuation Inputs

Under ASC Topic 820, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For our portfolio securities, fair value is generally the amount that we might reasonably expect to receive upon the current sale of the security. Under ASC Topic 820, the fair value measurement assumes that the sale occurs in the principal market for the security, or in the absence of a principal market, in the most advantageous market for the security. Under ASC Topic 820, if no market for the security exists or if we do not have access to the principal market, the security should be valued based on the sale occurring in a hypothetical market. The securities in which we invest are generally only purchased and sold in merger and acquisition transactions, in which case the entire portfolio company is sold to a third-party purchaser. As a result, unless we have the ability to control such a transaction, the assumed principal market for our securities is a hypothetical secondary market. The level 3 inputs to our valuation process reflect management’s best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in a hypothetical secondary market.

Enterprise Value Waterfall Approach

In valuing equity securities (including warrants), we estimate fair value using an “Enterprise Value Waterfall” valuation model. We estimate the enterprise value of a portfolio company and then allocate the enterprise value to the portfolio company’s securities in order of their relative liquidation preference. In addition, the model assumes that any outstanding debt or other securities that are senior to our equity securities are required to be repaid at par. Additionally, the Company estimates the fair value of a limited number of its debt securities using the Enterprise Value Waterfall approach in cases where the Company does not expect to receive full repayment.

To estimate the enterprise value of the portfolio company, we primarily use a valuation model based on a transaction multiple, which generally is the original transaction multiple, and measures of the portfolio company’s financial performance. In addition, we consider other factors, including but not limited to (i) offers from third-parties to purchase the portfolio company, (ii) the implied value of recent investments in the equity securities of the portfolio company, (iii) publicly available information regarding recent sales of private companies in comparable transactions and, (iv) when management believes there are comparable companies that are publicly traded, a review of these publicly traded companies and the market multiple of their equity securities.

The significant Level 3 inputs to the Enterprise Value Waterfall model are (i) an appropriate transaction multiple and (ii) a measure of the portfolio company’s financial performance, which generally is either earnings before interest, taxes, depreciation and amortization, as adjusted, or Adjusted EBITDA, or revenues. Such inputs can be based on historical operating results, projections of future operating results, or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. In determining the operating results input, we utilize the most recent portfolio company financial statements and forecasts available as of the valuation date. Management also consults with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Additionally, we consider some or all of the following factors:

| • |  | financial standing of the issuer of the security;

| • |  | comparison of the business and financial plan of the issuer with actual results;

| • |  | the size of the security held as it relates to the liquidity of the market for such security;

| • |  | pending public offering of common stock by the issuer of the security;

| • |  | pending reorganization activity affecting the issuer, such as merger or debt restructuring;

| • |  | ability of the issuer to obtain needed financing;

| • |  | changes in the economy affecting the issuer;

| • |  | financial statements and reports from portfolio company senior management and ownership;

| • |  | the type of security, the security’s cost at the date of purchase and any contractual restrictions on the disposition of the security;

| • |  | special reports prepared by analysts;

| • |  | information as to any transactions or offers with respect to the security and/or sales to third parties of similar securities;

| • |  | the issuer’s ability to make payments and the type of collateral;

| • |  | the current and forecasted earnings of the issuer;

| • |  | statistical ratios compared to lending standards and to other similar securities; and

| • |  | other pertinent factors.

S-34

##### Table of Contents

Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase in either the transaction multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher fair value for that security.

Income Approach

In valuing debt securities, we utilize an “Income Approach” model that considers factors including, but not limited to, (i) the stated yield on the debt security, (ii) the portfolio company’s current trailing twelve months, or TTM Adjusted EBITDA as compared to the portfolio company’s historical or projected Adjusted EBITDA as of the date the investment was made and the portfolio company’s anticipated Adjusted EBITDA for the next twelve months of operations, (iii) the portfolio company’s current Leverage Ratio (defined as the portfolio company’s total indebtedness divided by Adjusted EBITDA) as compared to its Leverage Ratio as of the date the investment was made, (iv) publicly available information regarding current pricing and credit metrics for similar proposed and executed investment transactions of private companies and (v) when management believes a relevant comparison exists, current pricing and credit metrics for similar proposed and executed investment transactions of publicly traded debt. In addition, we use a risk rating system to estimate the probability of default on the debt securities and the probability of loss if there is a default. This risk rating system covers both qualitative and quantitative aspects of the business and the securities held.

We consider the factors above, particularly any significant changes in the portfolio company’s results of operations and leverage, and develop an expectation of the yield that a hypothetical market participant would require when purchasing the debt investment (the “Required Rate of Return”). The Required Rate of Return, along with the Leverage Ratio and Adjusted EBITDA are the significant Level 3 inputs to the Income Approach model. For investments where the Leverage Ratio and Adjusted EBITDA have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from management’s expectations as of the date the investment was made, and where there have been no significant fluctuations in the market pricing for such investments, we may conclude that the Required Rate of Return is equal to the stated rate on the investment and therefore, the debt security is appropriately priced. In instances where we determine that the Required Rate of Return is different from the stated rate on the investment, we discount the contractual cash flows on the debt instrument using the Required Rate of Return in order to estimate the fair value of the debt security.

Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Rate of Return or Leverage Ratio inputs for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in the Adjusted EBITDA input for a particular debt security may result in a higher (lower) fair value for that security.

The fair value of our royalty rights are calculated based on specific provisions contained in the pertinent operating or royalty agreements. The determination of the fair value of such royalty rights is not a significant component of our valuation process.

Revenue Recognition

Interest and Dividend Income

Interest income, adjusted for amortization of premium and accretion of original issue discount, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when interest and/or principal payments on a loan become past due, or if we otherwise do not expect the borrower to be able to service its debt and other obligations, we will place the loan on non-accrual status and will generally cease recognizing interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The cessation of recognition of such interest will negatively impact the reported fair value of the investment. We write off any previously accrued and uncollected interest when it is determined that interest is no longer considered collectible. Dividend income is recorded on the ex-dividend date.

S-35

##### Table of Contents

We may have to include in our ICTI, interest income, including amortization of original issue discount, or OID, from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. As a result, we may be required to make a distribution to our stockholders in order to satisfy the minimum distribution requirements to maintain our RIC status, even though we will not have received and may not ever receive any corresponding cash amount. Additionally, any loss recognized by us for federal income tax purposes on previously accrued interest income will be treated as a capital loss.

Fee Income

Origination, facility, commitment, consent and other advance fees received in connection with loan agreements, or “loan origination fees,” are recorded as deferred income and recognized as investment income over the term of the loan. Upon prepayment of a loan, any unamortized loan origination fees are recognized as investment income. In the general course of our business, we receive certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received.

Payment-in-Kind Interest (PIK)

We currently hold, and we expect to hold in the future, some loans in our portfolio that contain a PIK interest provision. PIK interest, computed at the contractual rate specified in each loan agreement, is periodically added to the principal balance of the loan, rather than being paid to us in cash, and is recorded as interest income. Thus, the actual collection of PIK interest may be deferred until the time of debt principal repayment.

To maintain our status as a RIC, PIK interest, which is a non-cash source of income, is included in our taxable income and therefore affects the amount we are required to pay to stockholders in the form of dividends, even though we have not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if we otherwise do not expect the borrower to be able to service its debt and other obligations, we will place the loan on non-accrual status and will generally cease recognizing PIK interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. We write off any previously accrued and uncollected PIK interest when it is determined that the PIK interest is no longer collectible.

We may have to include in our ICTI, PIK interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. As a result, we may be required to make a distribution to our stockholders in order to satisfy the minimum distribution requirements, even though we will not have received and may not ever receive any corresponding cash amount.

Recently Issued Accounting Standards

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs , or ASU 2011-04. ASU 2011-04 clarifies the application of existing fair value measurement and disclosure requirements, changes the application of some requirements for measuring fair value and requires additional disclosure for fair value measurements categorized in Level 3 of the fair value hierarchy. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. We adopted this standard on January 1, 2012. The adoption of ASU 2011-04 did not have a material impact on our process for measuring fair values or on our financial statements, other than the inclusion of additional required disclosures.

Off-Balance Sheet Arrangements

We currently have no off-balance sheet arrangements.

Quantitative and Qualitative Disclosures About Market Risk.

During 2011 and the first six months of 2012, the United States economy continued to show modest improvements; however, during the third quarter of 2011, the financial markets experienced increased volatility and economic indicators suggested a further slowdown of the United States and European economies potentially leading to another recession. A prolonged slowdown in economic activity would likely have an adverse effect on a number of the industries in which some of our portfolio companies operate, and on certain of our portfolio companies as well. In addition, the recent sovereign debt crises may continue to impact the broader financial and credit markets and may continue to reduce the availability of debt and equity capital for the market as a whole and financial firms in particular.

During 2010, we experienced a $10.9 million increase in the fair value of our investment portfolio related to unrealized appreciation of investments. In 2011, we experienced a $6.4 million increase in the fair value of our investment portfolio related to unrealized appreciation of investments and in the first six months of 2012, we experienced a $1.4 million decrease in the fair value of our investment portfolio related to unrealized depreciation of investments.

As of June 30, 2012, the fair value of our non-accrual assets was approximately $2.9 million, which comprised approximately 0.5% of the total fair value of our portfolio, and the cost of our non-accrual assets was approximately $9.4 million, or 1.6% of the total cost of our portfolio.

In addition to these non-accrual assets, as of June 30, 2012, we had, on a fair value basis, approximately $20.1 million of debt investments, or 3.4% of the total fair value of our portfolio, which were current with respect to scheduled principal and interest payments, but which were carried at less than cost. The cost of these assets as of June 30, 2012 was approximately $28.5 million, or 4.8% of the total cost of our portfolio. Included in these amounts as of June 30, 2012 are two assets (our subordinate notes to Home Physicians, LLC and Home Physicians Holdings, LP) that are on non-accrual only with respect to the PIK interest component of the loan.

The volatile and stressed conditions of the equity and debt markets may continue for a prolonged period of time or worsen in the future. To the extent that recessionary conditions recur, the economy remains stagnate, any further downgrades to the U.S. government’s sovereign credit rating occur, the European credit crisis continues, or the economy fails to return to pre-recession levels, the financial position and results of operations of certain of the middle-market companies in our portfolio could be further affected adversely, which ultimately could lead to difficulty in our portfolio companies meeting debt service requirements and lead to an increase in defaults. There can be no assurance that the performance of our portfolio companies will not be further impacted by economic conditions, which could have a negative impact on our future results.

In addition, we are subject to interest rate risk. Interest rate risk is defined as the sensitivity of our current and future earnings to interest rate volatility, variability of spread relationships, the difference in re-pricing intervals between our assets and liabilities and the effect that interest rates may have on our cash flows. Changes in the general level of interest rates can affect our net interest income, which is the difference between the interest income earned on interest earning assets and our interest expense incurred in connection with our interest-bearing debt and liabilities. Changes in interest rates can also affect, among other things, our ability to acquire and originate loans and securities and the value of our investment portfolio. Our investment income is affected by fluctuations in various interest rates, including LIBOR and prime rates. We regularly measure exposure to interest rate risk and determine whether or not any hedging transactions are necessary to mitigate exposure to changes in interest rates. As of June 30, 2012, we were not a party to any hedging arrangements.

As of June 30, 2012, approximately 97.2%, or $518.6 million (at cost) of our debt portfolio investments bore interest at fixed rates and approximately 2.8%, or $14.7 million (at cost) of our debt portfolio investments bore interest at variable rates, which are either Prime-based or LIBOR-based. A 200 basis point increase or decrease in the interest rates on our variable-rate debt investments would increase or decrease, as applicable, our investment income by approximately $0.3 million on an annual basis. All of our pooled SBA-guaranteed

S-37

##### Table of Contents

debentures and the 2019 Notes bear interest at fixed rates. The Credit Facility bears interest, subject to our election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or (ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of (i) prime rate, (ii) the federal funds rate plus 0.5% or (iii) the adjusted one-month LIBOR plus 2.0%.

Because we currently borrow, and plan to borrow in the future, money to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds and the rate at which we invest the funds borrowed. Accordingly, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. In periods of rising interest rates, our cost of funds would increase, which could reduce our net investment income if there is not a corresponding increase in interest income generated by our investment portfolio.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of certain material U.S. federal income tax consequences relevant to the purchase, ownership and disposition of the Notes, but does not purport to be a complete analysis of all potential tax consequences. The discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the regulations promulgated thereunder by the U.S. Treasury (the “Treasury Regulations”), rulings and pronouncements issued by the Internal Revenue Service (the “IRS”), and judicial decisions, all as of the date hereof and all of which are subject to change at any time. Any such change may be applied retroactively in a manner that could adversely affect a holder of the Notes. We have not sought any ruling from the IRS with respect to the statements made and the conclusions reached in the following discussion, and there can be no assurance that the IRS will agree with such statements and conclusions.

This discussion does not address all of the U.S. federal income tax consequences that may be relevant to a holder in light of such holder’s particular circumstances or to holders subject to special rules, including, without limitation:

| • |  | banks, insurance companies and other financial institutions;

| • |  | U.S. expatriates and certain former citizens or long-term residents of the United States;

| • |  | holders subject to the alternative minimum tax;

| • |  | dealers in securities or currencies;

| • |  | traders in securities;

| • |  | partnerships, S corporations or other pass-through entities;

| • |  | U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

| • |  | controlled foreign corporations;

| • |  | tax-exempt organizations;

| • |  | passive foreign investment companies;

| • |  | persons holding the Notes as part of a “straddle,” “hedge,” “conversion transaction” or other risk reduction transaction; and

| • |  | persons deemed to sell the Notes under the constructive sale provisions of the Code.

In addition, this discussion is limited to persons purchasing the Notes for cash at original issue and at their original “issue price” within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the Notes are sold to the public for cash). Moreover, the effects of other U.S. federal tax laws (such as estate and gift tax laws) and any applicable state, local or foreign tax laws are not discussed. The discussion deals only with notes held as “capital assets” within the meaning of Section 1221 of the Code.

If a partnership or other entity taxable as a partnership holds the Notes, the tax treatment of the partners in the partnership generally will depend on the status of the particular partner in question and the activities of the partnership. Such partners should consult their tax advisors as to the specific tax consequences to them of holding the Notes indirectly through ownership of their partnership interests.

YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER THE FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

##### Table of Contents

U.S. Holders

The following is a summary of the material U.S. federal income tax consequences that will apply to you if you are a “U.S. holder” of the Notes. As used herein, “U.S. holder” means a beneficial owner of the Notes who is for U.S. federal income tax purposes:

| • |  | an individual who is a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the “substantial presence” test under Section 7701(b) of the Code;

| • |  | a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

| • |  | an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

| • |  | a trust, if a U.S. court can exercise primary supervision over the administration of the trust and one or more “United States persons” within the meaning of Section 7701(a)(30) of the Code can control all substantial trust decisions, or, if the trust was in existence on August 20, 1996, and it has elected to continue to be treated as a United States person.

Payments of Interest

Stated interest on the Notes generally will be taxable to a U.S. holder as ordinary income at the time that such interest is received or accrued, in accordance with such U.S. holder’s method of tax accounting for U.S. federal income tax purposes.

Sale or Other Taxable Disposition of Notes

A U.S. holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note equal to the difference between the amount realized upon the disposition (less a portion allocable to any accrued and unpaid interest, which will be taxable as interest) and the U.S. holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note generally will be equal to the amount that the U.S. holder paid for the note less any principal payments received by the U.S. holder. Any gain or loss will be a capital gain or loss, and will be a long-term capital gain or loss if the U.S. holder has held the note for more than one year at the time of disposition. Otherwise, such gain or loss will be a short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, generally will be subject to a reduced tax rate. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

A U.S. holder may be subject to information reporting and backup withholding when such holder receives interest payments on the Notes held or upon the proceeds received upon the sale or other disposition of such notes (including a redemption or retirement of the Notes). Certain holders generally are not subject to information reporting or backup withholding. A U.S. holder will be subject to backup withholding if such holder is not otherwise exempt and such holder:

| • |  | fails to furnish the holder’s taxpayer identification number (“TIN”), which, for an individual, ordinarily is his or her social security number;

| • |  | furnishes an incorrect TIN;

| • |  | is notified by the IRS that the holder has failed properly to report payments of interest or dividends; or

| • |  | fails to certify, under penalties of perjury, that the holder has furnished a correct TIN and that the IRS has not notified the holder that the holder is subject to backup withholding.

S-40

##### Table of Contents

U.S. holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. Backup withholding is not an additional tax, and taxpayers may use amounts withheld as a credit against their U.S. federal income tax liability or may claim a refund if they timely provide certain information to the IRS.

Unearned Income Medicare Contribution

After December 31, 2012, a tax of 3.8% will be imposed on the amount of “net investment income,” in the case of an individual, or undistributed “net investment income,” in the case of an estate or trust (other than a charitable trust), which exceeds certain threshold amounts. “Net investment income” as defined for United States federal Medicare contribution purposes generally includes interest payments and gain recognized from the sale or other disposition of the Notes. Qualified pension trusts, which are not subject to income taxes generally, and foreign individuals will not be subject to this tax. U.S. holders should consult their own tax advisors regarding the effect, if any, of this tax on their ownership and disposition of the Notes.

Non-U.S. Holders

The following is a summary of certain material U.S. federal income tax consequences that will apply to you if you are a “Non-U.S. holder” of the Notes. A “Non-U.S. holder” is a beneficial owner of the Notes who is not a U.S. holder or a partnership for federal income tax purposes. Special rules may apply to Non-U.S. holders that are subject to special treatment under the Code, including controlled foreign corporations, passive foreign investment companies, U.S. expatriates, and foreign persons eligible for benefits under an applicable income tax treaty with the U.S. Such Non-U.S. holders should consult their tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them including any reporting requirements.

Payments of Interest

Generally, interest income paid to a Non-U.S. holder that is not effectively connected with the Non-U.S. holder’s conduct of a U.S. trade or business is subject to withholding tax at a rate of 30% (or, if applicable, a lower treaty rate). Nevertheless, interest paid on a note to a Non-U.S. holder that is not effectively connected with the Non-U.S. holder’s conduct of a U.S. trade or business generally will not be subject to U.S. federal withholding tax provided that:

| • |  | such holder does not directly or indirectly, actually or constructively, own 10% or more of the total combined voting power of all classes of our voting stock;

| • |  | such holder is not a controlled foreign corporation that is related to us through actual or constructive stock ownership and is not a bank that received such note on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business; and

| • |  | either (1) the Non-U.S. holder certifies in a statement provided to us or the paying agent, under penalties of perjury, that it is not a “United States person” within the meaning of the Code and provides its name and address, (2) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the note on behalf of the Non-U.S. holder certifies to us or the paying agent under penalties of perjury that it, or the financial institution between it and the Non-U.S. holder, has received from the Non-U.S. holder a statement, under penalties of perjury, that such holder is not a United States person and provides us or the paying agent with a copy of such statement or (3) the Non-U.S. holder holds its note directly through a “qualified intermediary” and certain conditions are satisfied.

Even if the above conditions are not met, a Non-U.S. holder generally will be entitled to a reduction in or an exemption from withholding tax on interest if the Non-U.S. holder provides us or our agent with a properly executed IRS Form W-8BEN claiming an exemption from or reduction of the withholding tax under the benefit of a tax treaty between the United States and the Non-U.S. holder’s country of residence or a substantially similar

S-41

##### Table of Contents

substitute form. A Non-U.S. holder is required to inform the recipient of any change in the information on such statement within 30 days of such change. Special certification rules apply to Non-U.S. holders that are pass-through entities rather than corporations or individuals.

If interest paid to a Non-U.S. holder is effectively connected with the Non-U.S. holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, the Non-U.S. holder maintains a U.S. permanent establishment to which such interest is attributable), then, the Non-U.S. holder will be exempt from U.S. federal withholding tax, so long as the Non-U.S. holder has provided an IRS Form W-8ECI or substantially similar substitute form stating that the interest that the Non-U.S. holder receives on the Notes is effectively connected with the Non-U.S. holder’s conduct of a trade or business in the United States. In such a case, a Non-U.S. holder will be subject to tax on the interest it receives on a net income basis in the same manner as if such Non-U.S. holder were a U.S. holder. In addition, if the Non-U.S. holder is a foreign corporation, such interest may be subject to a branch profits tax at a rate of 30% or lower applicable treaty rate.

Sale or Other Taxable Disposition of Notes

Any gain realized by a Non-U.S. holder on the sale, exchange, retirement, redemption or other disposition of a note generally will not be subject to U.S. federal income tax unless:

| • |  | the gain is effectively connected with the Non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, the Non-U.S. holder maintains a U.S. permanent establishment to which such gain is attributable); or

| • |  | the Non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of sale, exchange or other disposition, certain conditions are met and the Non-U.S. holder is not eligible for relief under an applicable income tax treaty.

A Non-U.S. holder described in the first bullet point above will be required to pay U.S. federal income tax on the net gain derived from the sale generally in the same manner as if such Non-U.S. holder were a U.S. holder, and if such Non-U.S. holder is a foreign corporation, it may also be required to pay an additional branch profits tax at a 30% rate (or a lower rate if so specified by an applicable income tax treaty). A Non-U.S. holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or, if applicable, a lower treaty rate) on the gain derived from the sale, which may be offset by certain U.S. source capital losses, even though the Non-U.S. holder is not considered a resident of the United States.

Information Reporting and Backup Withholding

A Non-U.S. holder generally will not be subject to backup withholding and information reporting with respect to payments that we make to the Non-U.S. holder, provided that we do not have actual knowledge or reason to know that such holder is a “United States person,” within the meaning of the Code, and the holder has given us the statement described above under “Non-U.S. holders — Payments of Interest.” In addition, a Non-U.S. holder will not be subject to backup withholding or information reporting with respect to the proceeds of the sale or other disposition of a note (including a retirement or redemption of a note) within the United States or conducted through certain U.S.-related brokers, if the payor receives the statement described above and does not have actual knowledge or reason to know that such holder is a United States person or the holder otherwise establishes an exemption. However, the amount of interest that we pay to any Non-U.S. holder on the Notes will be reported to the Non-U.S. holder and to the IRS annually on an IRS Form 1042-S, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the Non-U.S. holder resides.

A Non-U.S. holder generally will be entitled to credit any amounts withheld under the backup withholding rules against the holder’s U.S. federal income tax liability or may claim a refund provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act

Legislation enacted in 2010 imposes a withholding tax of 30% on payments of interest or gross proceeds from the disposition of a debt instrument paid after December 31, 2012 to certain non-U.S. entities, including certain foreign financial institutions and investment funds, unless such non-U.S. entity complies with certain reporting requirements regarding its United States account holders and its United States owners. The date for implementation of these rules generally was extended by the IRS to January 1, 2014 for payments of fixed or determinable annual or periodic (FDAP) income, including interest, and to January 1, 2015 for other “withholdable payments,” including payments of gross proceeds. After these dates, payments of interest on, or gross proceeds from the sale of, the notes made to a non-United States entity generally will be subject to the new information reporting regime; however, the new withholding obligations will only apply to obligations issued after March 18, 2012, and proposed Treasury regulations would extend this grandfathering provision to obligations that are outstanding on January 1, 2013. Congress delegated broad authority to the United States Treasury Department to promulgate regulations to implement the new withholding and reporting regime. It cannot be predicted whether or how any regulations promulgated by the United States Treasury Department pursuant to this broad delegation of regulatory authority will affect holders of the notes. Prospective purchasers of the notes should consult their own tax advisors regarding the new withholding and reporting provisions.

Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the aggregate principal amount of Notes set forth opposite its name below.

Name |  | Principal Amount |

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the Notes sold under the underwriting agreement if any of these Notes are purchased. If an underwriter defaults, the underwriting agreement provides that, under the circumstances, the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the Notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We expect that delivery of the Notes will be made against payment therefor on or about October , 2012, which will be the third business day following the date of the pricing of the Notes. Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise.

Commissions and Discounts

An underwriting discount of % per Note will be paid by us. This underwriting discount will also apply to any Notes purchased pursuant to the over-allotment option.

The following table shows the total underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering. The information assumes either no exercise or full exercise by the underwriters of their over-allotment option.

|  | Per Note |  | Without Option |  |  | With Option |
Public offering price |  | 100% |  | $ | 50,000,000 |  |  | $ | 57,500,000 |

##### Table of Contents

The underwriters propose to offer some of the Notes to the public at the public offering price set forth on the cover page of this prospectus supplement and some of the Notes to certain other Financial Industry Regulatory Authority members at the public offering price less a concession not in excess of % of the aggregate principal amount of the Notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of % of the aggregate principal amount of the Notes. After the initial offering of the Notes to the public, the public offering price and such concessions may be changed. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

The expenses of the offering, not including the underwriting discount, are estimated at $300,000 and are payable by us.

Over-allotment Option

We have granted an option to the underwriters to purchase up to an additional $7,500,000 aggregate principal amount of the Notes offered hereby at the public offering price within 30 days from the date of this prospectus supplement solely to cover any over-allotments. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional Notes proportionate to that underwriter’s initial principal amount reflected in the table above.

No Sales of Similar Securities

Subject to certain exceptions, we have agreed not to directly or indirectly, offer, pledge, sell, contract to sell, grant any option for the sale of, or otherwise transfer or dispose of any debt securities issued or guaranteed by the Company or any securities convertible into or exercisable or exchangeable for debt securities issued or guaranteed by the Company or file any registration statement under the Securities Act with respect to any of the foregoing for a period of 30 days after the date of this prospectus supplement without first obtaining the written consent of Stifel, Nicolaus & Company, Incorporated, other than certain private sales of debt securities to a limited number of institutional investors. This consent may be given at any time without public notice.

Listing

The Notes are a new issue of securities with no established trading market. We intend to list the Notes on the NYSE. We expect trading in the Notes on the NYSE to begin within 30 days after the original issue date under the trading symbol “TCCA.” Currently there is no public market for the Notes.

We have been advised by the underwriters that they presently intend to make a market in the Notes after completion of the offering as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market in the Notes and any such market-making may be discontinued at any time in the sole discretion of the underwriters without any notice. Accordingly, no assurance can be given as to the liquidity of, or development of a public trading market for, the Notes. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

Price Stabilization, Short Positions

In connection with the offering, the underwriters may purchase and sell Notes in the open market. These transactions may include over-allotment, covering transactions and stabilizing transactions. Over-allotment involves sales of securities in excess of the aggregate principal amount of securities to be purchased by the underwriters in the offering, which creates a short position for the underwriters. Covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions consist of certain bids or purchases of securities made for the purpose of preventing or retarding a decline in the market price of the securities while the offering is in progress.

S-45

##### Table of Contents

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Any of these activities may cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be affected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time without any notice relating thereto.

Electronic Offer, Sale and Distribution of Notes

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by one or more of the underwriters and/or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a limited principal amount of the Notes for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations.

Other than the prospectus in electronic format, information contained in any other web site maintained by an underwriter or selling group member is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been endorsed by us and should not be relied on by investors in deciding whether to purchase any Notes.

Notes to Unaudited Consolidated Financial Statements

1. | ORGANIZATION, BASIS OF PRESENTATION AND BUSINESS

Organization

Triangle Capital Corporation and its wholly owned subsidiaries, including Triangle Mezzanine Fund LLLP (“Triangle SBIC”) and Triangle Mezzanine Fund II LP (“Triangle SBIC II”) (collectively, the “Company”), operate as a Business Development Company (“BDC”) under the Investment Company Act of 1940 (the “1940 Act”). Triangle SBIC and Triangle SBIC II are specialty finance limited partnerships formed to make investments primarily in middle market companies located throughout the United States. On September 11, 2003, Triangle SBIC was licensed to operate as a Small Business Investment Company (“SBIC”) under the authority of the United States Small Business Administration (“SBA”). On May 26, 2010, Triangle SBIC II obtained its license to operate as an SBIC. As SBICs, both Triangle SBIC and Triangle SBIC II are subject to a variety of regulations concerning, among other things, the size and nature of the companies in which they may invest and the structure of those investments.

The Company currently operates as a closed–end, non–diversified investment company and has elected to be treated as a BDC under the 1940 Act. The Company is internally managed by its executive officers under the supervision of its Board of Directors. The Company does not pay management or advisory fees, but instead incurs the operating costs associated with employing executive management and investment and portfolio management professionals.

Basis of Presentation

The financial statements of the Company include the accounts of the Company and its wholly-owned subsidiaries, including Triangle SBIC and Triangle SBIC II. Neither Triangle SBIC nor Triangle SBIC II consolidates portfolio company investments. The effects of all intercompany transactions between the Company and its subsidiaries have been eliminated in consolidation.

The accompanying unaudited financial statements are presented in conformity with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for the fair presentation of financial statements for the interim period, have been reflected in the unaudited consolidated financial statements. The current period’s results of operations are not necessarily indicative of results that ultimately may be achieved for the year. Additionally, the unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes thereto for the period ended December 31, 2011. Financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

Recently Issued Accounting Standards

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, or ASU 2011-04. ASU 2011-04 clarifies the application of existing fair value measurement and disclosure requirements, changes the application of some requirements for measuring fair value and requires additional disclosure for fair value measurements categorized in Level 3 of the fair value hierarchy. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. The Company adopted this standard on January 1, 2012. The

S-67

Notes to Unaudited Consolidated Financial Statements — (Continued)

adoption of ASU 2011-04 did not have a material impact on the Company’s process for measuring fair values or on its financial statements, other than the inclusion of additional required disclosures.

Reclassifications

Certain reclassifications have been made in the consolidated financial statements for the three and six months ended June 30, 2012 in order to conform to current presentation. The Company had historically included losses realized on the extinguishment of debt in “Amortization of deferred financing fees” in the Consolidated Statements of Operations. Effective January 1, 2012, the Company records losses on the extinguishment of debt as a separate line item in the Consolidated Statements of Operations. See Note 4 to the Consolidated Financial Statements for further discussion of deferred financing fees.

2. | INVESTMENTS

The Company primarily invests in subordinated debt (or 2 nd lien notes) of privately held companies. These subordinated debt investments generally are secured by a second priority security interest in the assets of the borrower. In addition, the Company generally invests in an equity instrument of the borrower, such as warrants to purchase common stock in the portfolio company or direct preferred or common equity interests. The Company also invests in senior debt (or 1 st lien notes) on a more limited basis.

The cost basis of our debt investments include any unamortized original issue discount, unamortized loan origination fees and payment–in–kind (“PIK”) interest, if any. Summaries of the composition of the Company’s investment portfolio at cost and fair value, and as a percentage of total investments, are shown in the following tables:

During the three months ended June 30, 2012, the Company made seven new investments totaling approximately $112.5 million and investments in three existing portfolio companies totaling approximately

S-68

##### Table of Contents

Notes to Unaudited Consolidated Financial Statements — (Continued)

$2.1 million. During the six months ended June 30, 2012, the Company made eleven new investments totaling approximately $153.5 million and investments in six existing portfolio companies totaling approximately $3.1 million.

During the three months ended June 30, 2011, the Company made five new investments totaling approximately $35.2 million and four investments in existing portfolio companies totaling approximately $32.8 million. During the six months ended June 30, 2011, the Company made ten new investments totaling approximately $86.8 million and investments in seven existing portfolio companies totaling approximately $49.5 million.

Investment Valuation Process

The Company has established and documented processes and methodologies for determining the fair values of portfolio company investments on a recurring basis in accordance with the 1940 Act and FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”). Under ASC Topic 820, a financial instrument is categorized within the ASC Topic 820 valuation hierarchy based upon the lowest level of input to the valuation process that is significant to the fair value measurement. The three levels of valuation inputs established by ASC Topic 820 are as follows:

Level 1 Inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 Inputs — include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 Inputs — include inputs that are unobservable and significant to the fair value measurement.

The Company’s investment portfolio is comprised of debt and equity instruments of privately held companies for which quoted prices or other inputs falling within the categories of Level 1 and Level 2 are not available. Therefore, the Company determines the fair value of its investments in good faith using level 3 inputs, pursuant to a valuation policy and process that is established by the management of the Company with the assistance of certain third-party advisors and subsequently approved by the Company’s Board of Directors. There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. The recorded fair values of the Company’s investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned.

The Company’s valuation process is led by the Company’s executive officers and managing directors. The Company’s valuation process begins with a quarterly review of each investment in the Company’s investment portfolio by the Company’s executive officers and investment committee. Valuations of each portfolio security are then prepared by the Company’s investment professionals, who have direct responsibility for the origination, management and monitoring of each investment. Under the Company’s valuation policy, each investment valuation is subject to (i) a review by the lead investment officer responsible for the portfolio company investment and (ii) a peer review by a second investment officer or executive officer of the Company. Generally, any investment that is valued below cost is subjected to review by one of the Company’s executive officers. After the peer review is complete, the Company engages two independent valuation firms, Duff & Phelps, LLC and Lincoln Partners Advisors LLC (collectively, the “Valuation Firms”), to provide third-party reviews of certain investments, as described further below. In addition, all investment valuations are provided to the Company’s independent registered public accounting firm each quarter in connection with quarterly review procedures and

S-69

##### Table of Contents

Notes to Unaudited Consolidated Financial Statements — (Continued)

the annual audit of our financial statements. Finally, the Board of Directors has the responsibility for reviewing and approving, in good faith, the fair value of the Company’s investments in accordance with the 1940 Act.

The Valuation Firms provide third party valuation consulting services to the Company which consist of certain limited procedures that the Company identified and requested the Valuation Firms to perform (hereinafter referred to as the “Procedures”). The Procedures are performed with respect to each portfolio company at least once in every calendar year and for new portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In addition, the Procedures are generally performed with respect to a portfolio company when there has been a significant change in the fair value of the investment. In certain instances, the Company may determine that it is not cost-effective, and as a result is not in the Company’s stockholders’ best interest, to request the Valuation Firms to perform the Procedures on one or more portfolio companies. Such instances include, but are not limited to, situations where the fair value of the investment in the portfolio company is determined to be insignificant relative to the total investment portfolio.

The total number of investments and the percentage of the investment portfolio on which the Procedures were performed are summarized below by period:

For the quarter ended: |  | Total companies |  |  | Percent of total investments at fair value(1) |
March 31, 2011 |  |  | 11 |  |  |  | 34 | %
June 30, 2011 |  |  | 13 |  |  |  | 26 | %
September 30, 2011 |  |  | 11 |  |  |  | 31 | %
December 31, 2011 |  |  | 12 |  |  |  | 22 | %
March 31, 2012 |  |  | 10 |  |  |  | 19 | %
June 30, 2012 |  |  | 14 |  |  |  | 21 | %

(1) | Exclusive of the fair value of new investments made during the quarter.

Upon completion of the Procedures, the Valuation Firms concluded that, with respect to each investment reviewed by each Valuation Firm, the fair value of those investments subjected to the Procedures appeared reasonable. The Company’s Board of Directors is ultimately responsible for determining the fair value of the Company’s investments in good faith.

Investment Valuation Inputs

Under ASC Topic 820, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For the Company’s portfolio securities, fair value is generally the amount that the Company might reasonably expect to receive upon the current sale of the security. Under ASC Topic 820, the fair value measurement assumes that the sale occurs in the principal market for the security, or in the absence of a principal market, in the most advantageous market for the security. Under ASC Topic 820, if no market for the security exists or if the Company does not have access to the principal market, the security should be valued based on the sale occurring in a hypothetical market. The securities in which the Company invests are generally only purchased and sold in merger and acquisition transactions, in which case the entire portfolio company is sold to a third-party purchaser. As a result, unless the Company has the ability to control such a transaction, the assumed principal market for the Company’s securities is a hypothetical secondary market. The level 3 inputs to the Company’s valuation process reflect the Company’s best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in a hypothetical secondary market.

Enterprise Value Waterfall Approach

In valuing equity securities (including warrants), the Company estimates fair value using an “Enterprise Value Waterfall” valuation model. The Company estimates the enterprise value of a portfolio company and then allocates the enterprise value to the portfolio company’s securities in order of their relative liquidation preference. In addition, the Company assumes that any outstanding debt or other securities that are senior to the Company’s equity securities are required to be repaid at par. Additionally, the Company estimates the fair value of a limited number of its debt securities using the Enterprise Value Waterfall approach in cases where the Company does not expect to receive full repayment.

To estimate the enterprise value of the portfolio company, the Company primarily uses a valuation model based on a transaction multiple, which generally is the original transaction multiple, and measures of the portfolio company’s financial performance. In addition, the Company considers other factors, including but not limited to (i) offers from third-parties to purchase the portfolio company, (ii) the implied value of recent investments in the equity securities of the portfolio company, (iii) publicly available information regarding recent sales of private companies in comparable transactions and, (iv) when the Company believes there are comparable companies that are publicly traded, a review of these publicly traded companies and the market multiple of their equity securities.

The significant Level 3 inputs to the Enterprise Value Waterfall model are (i) an appropriate transaction multiple and (ii) a measure of the portfolio company’s financial performance, which generally is either earnings before interest, taxes, depreciation and amortization, as adjusted (“Adjusted EBITDA”) or revenues. Such inputs can be based on historical operating results, projections of future operating results, or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. In determining the operating results input, the Company utilizes the most recent portfolio company financial statements and forecasts available as of the valuation date. The Company also consults with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase in either the transaction multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher fair value for that security.

Income Approach

In valuing debt securities, the Company utilizes an “Income Approach” model that considers factors including, but not limited to, (i) the stated yield on the debt security, (ii) the portfolio company’s current Adjusted EBITDA as compared to the portfolio company’s historical or projected Adjusted EBITDA as of the date the investment was made and the portfolio company’s anticipated Adjusted EBITDA for the next twelve months of operations, (iii) the portfolio company’s current Leverage Ratio (defined as the portfolio company’s total indebtedness divided by Adjusted EBITDA) as compared to its Leverage Ratio as of the date the investment was made, (iv) publicly available information regarding current pricing and credit metrics for similar proposed and executed investment transactions of private companies and (v) when the Company believes a relevant comparison exists, current pricing and credit metrics for similar proposed and executed investment transactions of publicly traded debt. In addition, the Company uses a risk rating system to estimate the probability of default on the debt securities and the probability of loss if there is a default. This risk rating system covers both qualitative and quantitative aspects of the business and the securities held.

The Company considers the factors above, particularly any significant changes in the portfolio company’s results of operations and leverage, and develops an expectation of the yield that a hypothetical market participant

would require when purchasing the debt investment (the “Required Rate of Return”). The Required Rate of Return, along with the Leverage Ratio and Adjusted EBITDA are the significant Level 3 inputs to the Income Approach model. For investments where the Leverage Ratio and Adjusted EBITDA have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from the Company’s expectations as of the date the investment was made, and where there have been no significant fluctuations in the market pricing for such investments, the Company may conclude that the Required Rate of Return is equal to the stated rate on the investment and therefore, the debt security is appropriately priced. In instances where the Company determines that the Required Rate of Return is different from the stated rate on the investment, the Company discounts the contractual cash flows on the debt instrument using the Required Rate of Return in order to estimate the fair value of the debt security.

Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Rate of Return or Leverage Ratio inputs for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in the Adjusted EBITDA input for a particular debt security may result in a higher (lower) fair value for that security.

The fair value of the Company’s royalty rights are calculated based on specific provisions contained in the pertinent operating or royalty agreements. The determination of the fair value of such royalty rights is not a significant component of the Company’s valuation process.

The ranges and weighted-average values of the significant Level 3 inputs used in the valuation of the Company’s debt and equity securities as of June 30, 2012 are summarized as follows:

All realized and unrealized gains and losses are included in earnings (changes in net assets) and are reported on separate line items within the Company’s Statements of Operations. Pre-tax net unrealized gains on investments of $0.2 million and $0.6 million, respectively, during the three and six months ended June 30, 2012 are related to portfolio company investments that were still held by the Company as of June 30, 2012. Pre-tax net unrealized gains on investments of $2.4 million and $7.2 million, respectively, during the three and six months ended June 30, 2011 are related to portfolio company investments that were still held by the Company as of June 30, 2011.

Warrants

When originating a debt security, the Company will sometimes receive warrants or other equity–related securities from the borrower. The Company determines the cost basis of the warrants or other equity–related securities received based upon their respective fair values on the date of receipt in proportion to the total fair value of the debt and warrants or other equity–related securities received. Any resulting difference between the face amount of the debt and its recorded fair value resulting from the assignment of value to the warrant or other equity instruments is treated as original issue discount and accreted into interest income over the life of the loan.

Realized Gain or Loss and Unrealized Appreciation or Depreciation of Portfolio Investments

Realized gains or losses are recorded upon the sale or liquidation of investments and are calculated as the difference between the net proceeds from the sale or liquidation, if any, and the cost basis of the investment using the specific identification method. Unrealized appreciation or depreciation reflects the difference between the fair value of the investments and the cost basis of the investments.

Investment Classification

In accordance with the provisions of the 1940 Act, the Company classifies investments by level of control. As defined in the 1940 Act, “Control Investments” are investments in those companies that the Company is deemed to “Control.” “Affiliate Investments” are investments in those companies that are “Affiliated Companies” of the Company, as defined in the 1940 Act, other than Control Investments. “Non–Control/Non–Affiliate Investments” are those that are neither Control Investments nor Affiliate Investments. Generally, under

S-74

##### Table of Contents

TRIANGLE CAPITAL CORPORATION

Notes to Unaudited Consolidated Financial Statements — (Continued)

the 1940 Act, the Company is deemed to control a company in which it has invested if the Company owns more than 25.0% of the voting securities of such company or has greater than 50.0% representation on its board. The Company is deemed to be an affiliate of a company in which the Company has invested if it owns between 5.0% and 25.0% of the voting securities of such company.

Investment Income

Interest income, adjusted for amortization of premium and accretion of original issue discount, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the loan on non-accrual status and will generally cease recognizing interest income on that loan until all principal and interest has been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any previously accrued and uncollected interest when it is determined that interest is no longer considered collectible. Dividend income is recorded on the ex–dividend date.

Fee Income

Origination, facility, commitment, consent and other advance fees received in connection with loan agreements (“Loan Origination Fees”) are recorded as deferred income and recognized as investment income over the term of the loan. Upon prepayment of a loan, any unamortized loan origination fees are recognized as investment income. In the general course of its business, the Company receives certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received.

Payment-in-Kind Interest

The Company currently holds, and expects to hold in the future, some loans in its portfolio that contain a payment–in–kind (“PIK”) interest provision. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan, rather than being paid to the Company in cash, and is recorded as interest income. Thus, the actual collection of PIK interest may be deferred until the time of debt principal repayment.

To maintain the Company’s status as a Regulated Investment Company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as Amended (the “Code”), PIK interest, which is a non-cash source of income, is included in the Company’s taxable income and therefore affects the amount it is required to pay to stockholders in the form of dividends, even though the Company has not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the loan on non-accrual status and will generally cease recognizing PIK interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any accrued and uncollected PIK interest when it is determined that the PIK interest is no longer collectible.

Concentration of Credit Risk

The Company’s investments are generally in lower middle–market companies in a variety of industries. At both June 30, 2012 and December 31, 2011, there were no individual investments greater than 10% of the fair

S-75

##### Table of Contents

Notes to Unaudited Consolidated Financial Statements — (Continued)

value of the Company’s portfolio. As of June 30, 2012 and December 31, 2011, the Company’s largest single portfolio company investment represented approximately 4.6% and 5.0%, respectively, of the fair value of the Company’s portfolio. Income, consisting of interest, dividends, fees, other investment income, and realization of gains or losses on equity interests, can fluctuate dramatically upon repayment of an investment or sale of an equity interest and in any given year can be highly concentrated among several portfolio companies.

The Company’s investments carry a number of risks including, but not limited to: 1) investing in lower middle market companies which have limited operating histories and financial resources; 2) investing in senior subordinated debt which ranks equal to or lower than debt held by other investors; and 3) holding investments that are not publicly traded and are subject to legal and other restrictions on resale, as well as other risks common to investing in below investment grade debt and equity instruments.

3. | INCOME TAXES

The Company has elected for federal income tax purposes to be treated as a RIC under the Code, and intends to make the required distributions to its stockholders as specified therein. In order to qualify as a RIC, the Company must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then the Company is generally required to pay income taxes only on the portion of its taxable income and gains it does not distribute (actually or constructively) and certain built-in gains. The Company has historically met its minimum distribution requirements and continually monitors its distribution requirements with the goal of ensuring compliance with the Code.

The minimum distribution requirements applicable to RICs require the Company to distribute to its stockholders at least 90% of its investment company taxable income (“ICTI”), as defined by the Code, each year. Depending on the level of ICTI earned in a tax year, the Company may choose to carry forward ICTI in excess of current year distributions into the next tax year and pay a 4% excise tax on such excess. Any such carryover ICTI must be distributed before the end of that next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI.

ICTI generally differs from net investment income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. The Company may be required to recognize ICTI in certain circumstances in which it does not receive cash. For example, if the Company holds debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments issued with warrants), the Company must include in ICTI 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 the Company in the same taxable year. The Company may also have to include in ICTI other amounts that it has not yet received in cash, such as (i) PIK interest income and (ii) interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. Because any original issue discount or other amounts accrued will be included in the Company’s ICTI for the year of accrual, the Company may be required to make a distribution to its stockholders in order to satisfy the minimum distribution requirements, even though the Company will not have received and may not ever receive any corresponding cash amount. ICTI also excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

The Company has certain wholly owned taxable subsidiaries (the “Taxable Subsidiaries”) each of which holds one or more of the Company’s portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiaries are consolidated for financial reporting purposes, such that the Company’s consolidated financial statements reflect the Company’s investments in the portfolio companies

S-76

##### Table of Contents

TRIANGLE CAPITAL CORPORATION

Notes to Unaudited Consolidated Financial Statements — (Continued)

owned by the Taxable Subsidiaries. The purpose of the Taxable Subsidiaries is to permit the Company to hold certain portfolio companies that are organized as limited liability companies (“LLCs”) (or other forms of pass–through entities) while satisfying the RIC tax requirement that at least 90% of the RIC’s gross revenue for income tax purposes must consist of qualifying investment income. Absent the Taxable Subsidiaries, a proportionate amount of any gross income of an LLC (or other pass–through entity) portfolio investment would flow through directly to the RIC. To the extent that such income did not consist of qualifying investment income, it could jeopardize the Company’s ability to qualify as a RIC and therefore cause the Company to incur significant amounts of federal income taxes. When LLCs (or other pass-through entities) are owned by the Taxable Subsidiaries, their income is taxed to the Taxable Subsidiaries and does not flow through to the RIC, thereby helping the Company preserve its RIC status and resultant tax advantages. The Taxable Subsidiaries are not consolidated for income tax purposes and may generate income tax expense as a result of their ownership of the portfolio companies. This income tax expense is reflected in the Company’s Statements of Operations.

For federal income tax purposes, the cost of investments owned at June 30, 2012 and December 31, 2011 was approximately $593.6 million and $500.7 million, respectively.

4. | LONG–TERM DEBT

SBA and SBA LMI Debentures

Interest payments on SBA debentures are payable semi–annually and there are no principal payments required on these debentures prior to maturity, nor do the debentures carry any prepayment penalties. The Company’s SBA Low or Moderate Income (“LMI”) debentures are five-year deferred interest debentures that are issued at a discount to par. The accretion of discount on SBA LMI debentures is classified as interest expense in the Company’s consolidated financial statements.

TRIANGLE CAPITAL CORPORATION

Notes to Unaudited Consolidated Financial Statements — (Continued)

Under the Small Business Investment Act and current SBA policy applicable to SBICs, an SBIC (or group of SBICs under common control) can have outstanding at any time, SBA-guaranteed debentures up to two times (and in certain cases, up to three times) the amount of its regulatory capital. As of June 30, 2012, the maximum statutory limit on the dollar amount of outstanding SBA-guaranteed debentures that can be issued by a single SBIC is $150.0 million and by a group of SBICs under common control is $225.0 million. As of June 30, 2012, Triangle SBIC has issued $139.6 million of SBA-guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of June 30, 2012, Triangle SBIC II has issued $75.0 million in face amount of SBA-guaranteed debentures. The weighted average interest rates for all SBA-guaranteed debentures as of June 30, 2012 and December 31, 2011 were 4.76% and 4.83%, respectively.

In addition to a one–time 1.0% fee on the total commitment from the SBA, the Company also pays a one–time 2.425% fee on the amount of each SBA-guaranteed debenture issued and a one-time 2.0% fee on the amount of each SBA-guaranteed LMI debenture issued. These fees are capitalized as deferred financing costs and are amortized over the term of the debt agreements using the effective interest method. Upon prepayment of an SBA-guaranteed debenture, any unamortized deferred financing costs related to the SBA-guaranteed debenture are written off and recognized as a loss on extinguishment of debt in the Consolidated Statements of Operations.

Credit Facility

In May 2011, the Company entered into a three-year senior secured credit facility with an initial commitment of $50.0 million (the “Credit Facility”). In November 2011, we closed an expansion of the Credit Facility, which included the addition of one new lender, from $50.0 million to $75.0 million. The purpose of the Credit Facility is to provide additional liquidity in support of future investment and operational activities. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and has an accordion feature which allows for an increase in the total loan size up to $90.0 million and also contains two one-year extension options, bringing the total potential commitment and funding period to five years from closing. The Credit Facility, which is structured to operate like a revolving credit facility, is secured primarily by Triangle Capital Corporation’s assets, excluding the assets of Triangle SBIC and Triangle SBIC II.

Borrowings under the Credit Facility bear interest, subject to the Company’s election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or (ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of (i) prime rate, (ii) the federal funds rate plus 0.5% or (iii) the adjusted one-month LIBOR plus 2.0%. The Company pays unused commitment fees of 0.375% per annum, which are included with Interest and other credit facility fees on the Company’s Consolidated Statement of Operations. As of June 30, 2012, the Company had no borrowings outstanding under the Credit Facility. As of December 31, 2011, the Company had $15.0 million in borrowings outstanding under the Credit Facility with an interest rate of 5.2%.

The Credit Facility contains certain affirmative and negative covenants, including but not limited to (i) maintaining a minimum interest coverage ratio, (ii) maintaining a minimum liquidity ratio and (iii) maintaining minimum consolidated tangible net worth. As of June 30, 2012, the Company was in compliance with all covenants of the Credit Facility.

Senior Notes Due 2019

In March 2012, the Company issued $69.0 million of senior unsecured notes (the “Senior Notes”). The Senior Notes mature on March 15, 2019, and may be redeemed in whole or in part at any time or from time to time at the Company’s option on or after March 15, 2015. The Senior Notes bear interest at a rate of 7.00% per year payable quarterly on March 15, June 15, September 15 and December 15 of each year, beginning June 15, 2012. The net proceeds to the Company from the sale of the Senior Notes, after underwriting discounts and offering expenses, were approximately $66.8 million.

5. | EQUITY-BASED AND OTHER COMPENSATION PLANS

The Company’s Board of Directors and stockholders have approved the Triangle Capital Corporation Amended and Restated 2007 Equity Incentive Plan (the “Plan”), under which there are 2,400,000 shares of the Company’s Common Stock authorized for issuance. Under the Plan, the Board of Directors (or Compensation Committee, if delegated administrative authority by the Board of Directors) may award stock options, restricted stock or other stock based incentive awards to executive officers, employees and directors. Equity-based awards granted under the Plan to independent directors generally will vest over a one-year period and equity-based awards granted under the Plan to executive officers and employees generally will vest ratably over a four-year period.

The Company accounts for its equity-based compensation plan using the fair value method, as prescribed by ASC Topic 718, 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 this fair value to compensation expense over the requisite service period or vesting term.

The following table presents information with respect to the Plan for the six months ended June 30, 2012 and 2011:

|  | Six Months Ended June 30, 2012 |  |  | Six Months Ended June 30, 2011 |
|  | Number of Shares |  |  | Weighted-Average Grant-Date Fair Value per Share |  |  | Number of Shares |  |  | Weighted-Average Grant-Date Fair Value per Share |
Unvested shares, beginning of period |  |  | 359,555 |  |  | $ | 15.39 |  |  |  | 302,698 |  |  | $ | 11.40 |
Shares granted during the period |  |  | 235,086 |  |  | $ | 19.00 |  |  |  | 161,174 |  |  | $ | 20.37 |
Shares vested during the period |  |  | (140,464 | ) |  | $ | 13.42 |  |  |  | (104,317 | ) |  | $ | 11.53 |
Unvested shares, end of period |  |  | 454,177 |  |  | $ | 17.87 |  |  |  | 359,555 |  |  | $ | 15.39 |

In the three and six months ended June 30, 2012, the Company recognized equity-based compensation expense of approximately $0.7 million and $1.4 million, respectively. In the three and six months ended June 30, 2011, the Company recognized equity-based compensation expense of approximately $0.5 and $0.9 million, respectively. This expense is included in general and administrative expenses in the Company’s consolidated Statements of Operations.

As of June 30, 2012, there was approximately $6.9 million of total unrecognized compensation cost, related to the Company’s non-vested restricted shares. This cost is expected to be recognized over a weighted-average period of approximately 2.3 years.

The Company’s Board of Directors has adopted a nonqualified deferred compensation plan covering the Company’s executive officers and key employees. Any compensation deferred and the Company’s contributions will earn a return based on the returns on certain investments designated by the Compensation Committee of the Company’s Board of Directors. Participants are 100% vested in amounts deferred under the deferred compensation plan and the earnings thereon. Contributions to the plan and earnings thereon vest ratably over a four-year period.

The Company maintains a 401(k) plan in which all full-time employees who are at least 21 years of age and have 90 days of service are eligible to participate and receive employer contributions. Eligible employees may

contribute a portion of their compensation on a pretax basis into the 401(k) plan up to the maximum amount allowed under the Code, and direct the investment of their contributions.

Units

We may offer, from time to time, in one or more offerings or series, together or separately, up to $500,000,000 of our common stock, preferred stock, units, subscription rights, debt securities, or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities, which we refer to, collectively, as the “securities.” We may sell our common stock through underwriters or dealers, “at-the-market” to or through a market maker into an existing trading market or otherwise directly to one or more purchasers or through agents or through a combination of methods of sale. The identities of such underwriters, dealers, market makers or agents, as the case may be, will be described in one or more supplements to this prospectus. The securities may be offered at prices and on terms to be described in one or more supplements to this prospectus.

We may offer shares of common stock at a discount to net asset value per share in certain circumstances. On May 2, 2012, our common stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. Sales of common stock at prices below net asset value per share dilute the interests of existing stockholders, have the effect of reducing our net asset value per share and may reduce our market price per share. In addition, continuous sales of common stock below net asset value may have a negative impact on total returns and could have a negative impact on the market price of our shares of common stock. See “Risk Factors” on page 15 and “Sales of Common Stock Below Net Asset Value” on page 124 of this prospectus for more information.

Our stockholders did not specify a maximum discount below net asset value at which we are able to issue our common stock; however, we do not intend to issue shares of our common stock below net asset value unless our Board of Directors determines that it would be in our stockholders’ best interests to do so. Shares of closed-end investment companies such as us frequently trade at a discount to their net asset value. This risk 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 above, at or below net asset value. You should read this prospectus and the applicable prospectus supplement carefully before you invest in our common stock.

Our securities may be offered directly to one or more purchasers through agents designated from time to time by us, or to or through underwriters or dealers. The prospectus supplement relating to the offering will identify any agents or underwriters involved in the sale of our securities, and will disclose any applicable purchase price, fee, commission or discount arrangement between us and our agents or underwriters or among our underwriters or the basis upon which such amount may be calculated. See “Plan of Distribution.” We may not sell any of our securities through agents, underwriters or dealers without delivery of a prospectus supplement describing the method and terms of the offering of such securities, which must be delivered to each purchaser at, or prior to, the earlier of delivery of a confirmation of sale or delivery of the securities.

We are a specialty finance company that provides customized financing solutions to lower middle market companies located throughout the United States. Our goal is to be the premier provider of capital to these companies. Our investment objective is to seek attractive returns by generating current income from our debt investments and capital appreciation from our equity related investments. We are an internally managed, closed-end, non-diversified management investment company that has elected to be treated as a business development company under the Investment Company Act of 1940.

Our common stock is listed on the New York Stock Exchange under the symbol “TCAP.” On June 5, 2012, the last reported sale price of our common stock on the New York Stock Exchange was $20.46 per share and our net asset value on March 31, 2012 was $15.12 per share. Our 7.00% senior notes due 2019 are listed on the New York Stock Exchange under the symbol “TCC.” On June 5, 2012, the last reported sale price of our 7.00% senior notes due 2019 on the New York Stock Exchange was $25.55 per share.

Investing in our securities is speculative and involves numerous risks, and you could lose your entire investment if any of the risks occur. Among these risks is the risk associated with leverage and dilution. For more information regarding these risks, please see “Risk Factors” beginning on page 15.

The Securities and Exchange Commission has not approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus may not be used to consummate sales of securities unless accompanied by a prospectus supplement.

PROSPECTUS SUMMARY

This summary highlights some of the information in this prospectus. It is not complete and may not contain all of the information that you may want to consider. You should read the entire prospectus and any prospectus supplement carefully, including “Risk Factors,” “Selected Consolidated Financial and Other Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements contained elsewhere in this prospectus.

Triangle Capital Corporation is a Maryland corporation incorporated on October 10, 2006, for the purpose of acquiring Triangle Mezzanine Fund LLLP, or Triangle SBIC, and its general partner, Triangle Mezzanine LLC, or TML, raising capital in its initial public offering, or IPO, which closed on February 21, 2007 and, thereafter, operating as an internally managed business development company, or BDC, under the Investment Company Act of 1940, or the 1940 Act. Triangle SBIC is licensed as a small business investment company, or SBIC, by the United States Small Business Administration, or SBA. Simultaneously with the consummation of our IPO, we acquired all of the equity interests in Triangle SBIC and TML as described elsewhere in this prospectus under “Formation Transactions,” whereby Triangle SBIC became our wholly owned subsidiary. Triangle Mezzanine Fund II LP, or Triangle SBIC II, is a recently formed, wholly owned subsidiary of Triangle Capital Corporation that is licensed by the SBA to operate as an SBIC. Unless otherwise noted in this prospectus or any accompanying prospectus supplement, the terms “we,” “us,” “our,” the “Company” and “Triangle” refer to Triangle SBIC prior to the IPO and to Triangle Capital Corporation and its subsidiaries, including Triangle SBIC and Triangle SBIC II, currently existing.

Triangle Capital Corporation

Triangle Capital Corporation is a specialty finance company that provides customized financing to lower middle market companies located throughout the United States. Our goal is to be the premier provider of capital to these companies. Our investment objective is to seek attractive returns by generating current income from our debt investments and capital appreciation from our equity related investments. Our investment philosophy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in subordinated debt securities secured by second lien security interests in portfolio company assets, coupled with equity interests. On a more limited basis, we also invest in senior debt securities secured by first lien security interests in portfolio companies.

We focus on investments in companies with a history of generating revenues and positive cash flow, an established market position and a proven management team with a strong operating discipline. Our target portfolio company has annual revenues between $20.0 and $200.0 million and annual earnings before interest, taxes, depreciation and amortization, or EBITDA, between $3.0 and $20.0 million. We believe that these companies have less access to capital and that the market for such capital is underserved relative to larger companies. Companies of this size are generally privately held and are less well known to traditional capital sources such as commercial and investment banks.

Our investments generally range from $5.0 to $25.0 million per portfolio company. In certain situations, we have partnered with other funds to provide larger financing commitments. We are continuing to operate Triangle SBIC and Triangle SBIC II as SBICs and to utilize the proceeds of the sale of SBA guaranteed debentures, referred to herein as SBA leverage, to enhance returns to our stockholders. As of March 31, 2012, we had investments in 66 portfolio companies, with an aggregate cost of $534.9 million.

Our principal executive offices are located at 3700 Glenwood Avenue, Suite 530, Raleigh, North Carolina 27612, and our telephone number is 919-719-4770. We maintain a website on the Internet at www.tcap.com. Information contained on our website is not incorporated by reference into this prospectus or any prospectus supplement, and you should not consider that information to be part of this prospectus.

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.

| • |  | 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 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 opportunities associated with 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 attractiveness, which we believe allows 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 participating in regular meetings of the portfolio company’s board of directors. We believe that our initial and ongoing portfolio review process allows us to effectively monitor the performance and prospects of our portfolio companies.

| • |  | Taking Advantage of Low Cost Debentures Guaranteed by the SBA. The licenses of Triangle SBIC and Triangle SBIC II to do business as SBICs allow them (subject to availability and continued regulatory compliance) 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.

Risk Factors

Investing in our securities involves a high degree of risk. You should consider carefully the information found in “Risk Factors,” including the following risks:

| • |  | 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.

| • |  | 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 estimate of fair value and, as a result, there is and will continue to be uncertainty as to the value of our portfolio investments.

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

| • |  | We may face increasing competition for investment opportunities.

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

| • |  | Triangle SBIC and Triangle SBIC II are licensed by the SBA, and therefore subject to SBA regulations.

| • |  | 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, through Triangle SBIC and Triangle SBIC II, 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 Triangle SBIC and Triangle SBIC II that are superior to the claims of our stockholders.

| • |  | We will be subject to corporate level income tax if we are unable to qualify as a regulated investment company, or RIC, under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code.

| • |  | We may not be able to pay you dividends, our dividends may not grow over time, and a portion of dividends paid to you may be a return of capital.

| • |  | Because we intend to continue to distribute substantially all of our 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.

| • |  | We may have difficulty paying our required distributions if we recognize income before or without receiving cash representing such income, including income from amortization of original issue discount, contractual payment-in-kind, or PIK, interest, contractual preferred dividends, or amortization of market discount. 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.

| • |  | 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.

##### Table of Contents

| • |  | Our investments in portfolio companies involve higher levels of risk, and we could lose all or part of any of our investments. Investing in our portfolio companies involves a number of significant risks. Among other factors, 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 underperformance 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.

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

| • |  | 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.

| • |  | Shares of closed-end investment companies, including BDCs, may trade at a discount to their 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.

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

Our Investment Criteria

We utilize the following criteria and guidelines in evaluating investment opportunities. However, not all of these criteria and guidelines have been, or will be, met in connection with each of our investments.

| • |  | 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 generally do not invest in start-up companies, distressed situations, “turn-around” situations or companies that we believe have unproven business plans.

##### Table of Contents

| • |  | 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 will look for portfolio companies that we believe have sufficient value beyond the layer of the capital structure in which we invest.

See “Business — Our Investment Criteria” for a more complete discussion of our investment criteria.

Our Investment Portfolio

As of March 31, 2012, we had investments in 66 portfolio companies with an aggregate cost of approximately $534.9 million. As of March 31, 2012, we had no investments that represented more than 10% of the total fair value of our investment portfolio. As of March 31, 2012, the weighted average yield on our outstanding debt investments other than non-accrual debt investments (including payment-in-kind, or PIK, interest) was approximately 15.1%. The weighted average yield on all of our outstanding investments (including equity and equity-linked investments but excluding non-accrual debt investments) was approximately 14.0% as of March 31, 2012. The weighted average yield on all of our outstanding investments (including equity and equity-linked investments and non-accrual debt investments) was approximately 13.8% as of March 31, 2012. There is no assurance that the portfolio yields will remain at these levels after the offering.

Regulation

We are a closed-end, non-diversified management investment company that has elected to be treated as a BDC under the 1940 Act. In addition, Triangle SBIC has elected to be treated as a BDC. We are internally managed by our executive officers under the supervision of our Board of Directors. As a result, we do not pay any external investment advisory fees, but instead we incur the operating costs associated with employing investment and portfolio management professionals.

As a BDC, we are required to comply with numerous regulatory requirements. We are permitted to, and expect to, finance our investments using debt and equity. However, our ability to use debt is limited in certain significant respects. See “Regulation.” Commencing with our taxable year ended December 31, 2007, we have qualified and elected to be treated for U.S. federal income tax purposes as a regulated investment company, or RIC, under the Internal Revenue Code of 1986, as amended, or the Code. Accordingly, we generally will not pay corporate-level federal income taxes on any net ordinary income or capital gains that we distribute to our stockholders out of our current and accumulated earnings and profits. To maintain our RIC tax treatment, we must meet specified source-of-income and asset diversification requirements and distribute annually 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. See “Material U.S. Federal Income Tax Considerations.”

The Offering

We may offer, from time to time, up to $500,000,000 worth of our securities, on terms to be determined at the time of the offering. Our securities may be offered at prices and on terms to be disclosed in one or more prospectus supplements.

We may sell or otherwise issue shares of common stock at a discount to net asset value per share at prices approximating market value less selling expenses upon approval of our Board of Directors, including a majority of our independent directors, in certain circumstances. On May 2, 2012, our common stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. See “Sales of Common Stock Below Net Asset Value” in this prospectus and in any accompanying prospectus supplement, if applicable. Sales or other issuances of common stock at prices below net asset value per share dilute the interests of existing stockholders, have the effect of reducing our net asset value per share and may reduce our market price per share.

Our stockholders did not specify a maximum discount below net asset value at which we are able to sell or otherwise issue our common stock; however, we do not intend to sell or otherwise issue shares of our common stock below net asset value unless our Board of Directors determines that it would be in our stockholders’ best interest to do so.

Our securities may be offered directly to one or more purchasers by us or through agents designated from time to time by us, or to or through underwriters or dealers. The prospectus supplement relating to the offering will disclose the terms of the offering, including the name or names of any agents or underwriters involved in the sale of our securities by us, the purchase price, and any fee, commission or discount arrangement between us and our agents or underwriters or among our underwriters or the basis upon which such amount may be calculated. See “Plan of Distribution.” We may not sell any of our securities through agents, underwriters or dealers without delivery of a prospectus supplement describing the method and terms of the offering of our securities.

##### Table of Contents

Set forth below is additional information regarding the offering of our securities:

New York Stock Exchange symbol | “TCAP”

Use of proceeds | We intend to use the net proceeds from selling our securities to make investments in lower middle market companies in accordance with our investment objective and strategies and for working capital and general corporate purposes.

Dividends and distributions | We pay quarterly dividends to our stockholders out of assets legally available for distribution. Our dividends, if any, will be determined by our Board of Directors. Our ability to declare dividends depends on our earnings, our overall financial condition (including our liquidity position), maintenace of our RIC status and such other factors as our Board of Directors may deem relevant from time to time.

| When we make distributions, we will be required to determine the extent to which such distributions are paid out of current or accumulated 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 federal tax purposes. In the future, our distributions may include a return of capital.

Taxation | We have elected to be treated as a RIC. Accordingly, we generally will not pay corporate-level federal income taxes on any net ordinary income or capital gains that we distribute to our stockholders as dividends. To maintain our RIC tax treatment, we must meet specified source-of-income and asset diversification requirements and distribute annually 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.

| 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% 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. See “Material U.S. Federal Income Tax Considerations.”

Dividend reinvestment plan | We have a dividend reinvestment plan for our stockholders. The dividend reinvestment plan is an “opt out” dividend reinvestment plan. As a result, if we declare a dividend, then stockholders’ cash dividends will be automatically reinvested in additional shares of our common stock, unless they specifically “opt out” of the dividend reinvestment plan so as to receive cash dividends. Stockholders who receive distributions in the form of stock will be subject to the same federal, state and local tax consequences as stockholders who elect to receive their distributions in cash. See “Dividend Reinvestment Plan.”

##### Table of Contents

Trading at a discount | Shares of closed-end investment companies frequently trade at a discount to their net asset value. This risk 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 above, at or below net asset value.

Sales of common stock below net asset value | The offering price per share of our common stock exclusive of any underwriting commissions or discounts will not be less than the net asset value per share of our common stock at the time we make the offering except (1) in connection with a rights offering to our existing stockholders, (2) with the consent of the majority of our common stockholders and approval of our Board of Directors, or (3) under such circumstances as the Securities and Exchange Commission, or the SEC, may permit. On May 2, 2012, our common stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or our 2013 Annual Meeting of Stockholders. Sales or other issuances by us of our common stock at a discount from our net asset value pose potential risks for our existing stockholders whether or not they participate in the offering, as well as for new investors who participate in the offering. See “Sales of Common Stock Below Net Asset Value” in this prospectus and in the prospectus supplement, if applicable.

Leverage | We borrow funds to make additional investments. We use this practice, which is known as “leverage,” to attempt to increase returns to our stockholders, but it involves significant risks. See “Risk Factors,” “Senior Securities” and “Regulation — Senior Securities.” With certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, as defined in the 1940 Act, equals at least 200% after such borrowing. The amount of leverage that we employ at any particular time will depend on our investment committee’s and our Board of Directors’ assessments of market and other factors at the time of any proposed borrowing. In addition, the maximum amount of leverage that our SBIC subsidaries can have outstanding is $225 million.

Available information | We are required to file periodic reports, current reports, proxy statements and other information with the SEC. This information is available on the SEC’s Internet website at www.sec.gov. You can also inspect any materials we file with the SEC, without charge, at the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. Please call the SEC at 1-800-SEC-0330 for further information on the Public Reference Room. We intend to provide much of the same information on our website at www.tcap.com. Information contained on our website is not part of this prospectus or any prospectus supplement and should not be relied upon as such.

FEES AND EXPENSES

The following table is intended to assist you in understanding our consolidated costs and expenses that an investor in this offering will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “you,” “us” or “Triangle,” or that “we” will pay fees or expenses, common stockholders will indirectly bear such fees or expenses as investors in us.

Stockholder Transaction Expenses: |  |
Sales load paid by us (as a percentage of offering price) |  | —(1)
Offering expenses borne by us |  | —(2)
Dividend reinvestment plan expenses |  | —(3)
Total stockholder transaction expenses paid by us (as a percentage of offering price) |  | —(4)
Annual Expenses (as a percentage of net assets attributable to common stock): |  |
Interest payments on borrowed funds |  | 2.73%(5)
Interest payments on debt securities |  | 1.16%(6)
Other expenses |  | 3.52%(7)
Total annual expenses |  | 7.41%(8)

(1) | In the event that securities to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will disclose the applicable sales load.

(2) | In the event that we conduct an offering of any of our securities, a corresponding prospectus supplement will disclose the estimated offering expenses because they will be ultimately borne by us.

(3) | The expenses of administering our dividend reinvestment plan are included in other expenses.

(4) | Total stockholder transaction expenses may include sales load and will be disclosed in a future prospectus supplement, if any.

(5) | Interest payments on borrowed funds represent our estimated annual interest payments on our outstanding SBA-guaranteed debentures and on any outstanding borrowings under our line of credit.

(6) | Interest payments on debt securities represent our estimated annual interest payments on our Senior Notes due 2019. We do not have any class of securities outstanding other than common stock and our Senior Notes due 2019.

(7) | Other expenses represent our estimated annual operating expenses, excluding interest payments on borrowed funds, interest payments on debt securities, and if we issue preferred stock, dividends on preferred stock. We currently do not have any class of securities outstanding other than common stock and our Senior Notes due 2019. We do not have an investment adviser and are internally managed by our executive officers under the supervision of our Board of Directors. As a result, we do not pay investment advisory fees, but instead we pay the operating costs associated with employing investment management professionals.

(8) | The total annual expenses are the sum of interest payments on borrowed funds, interest payments on debt securities and other expenses. “Total annual expenses” as a percentage of average net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. The SEC requires that the “Total annual expenses” percentage be calculated as a percentage of average net assets, rather than average total assets, which includes assets that have been funded with borrowed money.

Example

The following example is required by the SEC and demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in us. In calculating the following expense amounts, we assumed that our operating expenses would remain at the levels set forth in the table above. In the event that shares to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will restate this example to reflect the applicable sales load.

|  | 1 Year |  |  | 3 Years |  |  | 5 Years |  |  | 10 Years |
You would pay the following expenses on a $1,000 investment, assuming a 5.0% annual return |  | $ | 76 |  |  | $ | 222 |  |  | $ | 361 |  |  | $ | 677 |

##### Table of Contents

The example and the expenses in the tables above should not be considered a representation of our future expenses, and actual expenses may be greater or lesser than those shown. While the example assumes, as required by the SEC, a 5.0% annual return, our performance will vary and may result in a return greater or less than 5.0%. The table above does not reflect borrowings under our credit facility that we may employ in the future. “Other expenses” are based on estimated amounts for the current fiscal year. In addition, while the example assumes reinvestment of all dividends at net asset value, participants in our dividend reinvestment plan will receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend payable to a participant by the market price per share of our common stock at the close of trading on the dividend payment date, which may be at, above or below net asset value. See “Dividend Reinvestment Plan” for additional information regarding our dividend reinvestment plan.

RISK FACTORS

Investing in our securities involves a number of significant risks. In addition to the other information contained in this prospectus and any accompanying prospectus supplement, 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 and the trading price of our securities could decline, and you may lose all or part of your investment.

Risks Relating to Our Business and Structure

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

Our ability to continue to achieve our investment objective will depend on our ability to effectively manage and deploy our capital, which will depend, in turn, on our management team’s ability to continue to identify, evaluate, invest in, and monitor companies that meet our investment criteria. We cannot assure you that we will continue to achieve our investment objective.

Accomplishing this result on a cost-effective basis will be largely a function of our management 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 management team and our investment professionals may also be called upon to provide managerial assistance to 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 in a manner commensurate with the increased capital available to us as a result of recent offerings of our securities, 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 in this prospectus, or any prospectus supplement, it could negatively impact our ability to pay distributions and cause you to lose part or all of your investment.

Recent market conditions have impacted debt and equity capital markets in the United States, and we do not know if these conditions will improve in the near future.

Beginning in the third quarter of 2007, global credit and other financial markets began to suffer substantial stress, volatility, illiquidity and disruption. These forces reached extraordinary levels in late 2008, resulting in the bankruptcy of, the acquisition of, or government intervention in the affairs of several major domestic and international financial institutions. In particular, the financial services sector was negatively impacted by significant write-offs as the value of the assets held by financial firms declined, impairing their capital positions and abilities to lend and invest. We believe that such value declines were exacerbated by widespread forced liquidations as leveraged holders of financial assets, faced with declining prices, were compelled to sell to meet margin requirements and maintain compliance with applicable capital standards. Such forced liquidations also impaired or eliminated many investors and investment vehicles, leading to a decline in the supply of capital for investment and depressed pricing levels for many assets. These events significantly diminished overall confidence in the debt and equity markets, engendered unprecedented declines in the values of certain assets, and caused extreme economic uncertainty.

Further, recent U.S. debt ceiling and budget deficit concerns, together with signs of deteriorating sovereign debt conditions in Europe, have increased the possibility of additional credit-rating downgrades and economic slowdowns. Although U.S. lawmakers passed legislation to raise the federal debt ceiling, Standard & Poor’s Ratings Services lowered its long-term sovereign credit rating on the U.S. from “AAA” to “AA+” in August 2011. The impact of this or any further downgrades to the U.S. government’s sovereign credit rating, or its perceived creditworthiness, and the impact of the current crisis in Europe with respect to the ability of certain European Union countries to continue to service their sovereign debt obligations is inherently unpredictable and could adversely affect the U.S. and global financial markets and economic conditions. There can be no assurance that governmental or other measures to aid economic recovery will be effective. These developments, and the government’s credit concerns in general, 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, the decreased credit rating could create broader financial turmoil and uncertainty, which may weigh heavily on our stock price.

Nonetheless, since March 2009, there have been signs that the global credit and other financial market conditions have improved as stability has increased throughout the international financial system and many public market indices have experienced positive total returns. Concentrated policy initiatives undertaken by central banks and governments appear to have curtailed the incidence of large-scale failures within the global financial system. Concurrently, investor confidence, financial indicators, capital markets activity and asset prices have shown signs of marked improvement since the second quarter of 2009. However, while financial conditions have improved, domestic unemployment rates remain high, and economic activity remains subdued. In addition, there are early signs that many businesses and industries are experiencing inflationary pressures, both internationally and domestically. These conditions could increase our funding costs, limit our access to the capital markets, decrease our ability to borrow under our line of credit or result in a decision by other lenders not to extend credit to us. These events could prevent us from increasing our investment originations and negatively impact our operating results.

Our investment portfolio is and will continue to be recorded at fair value as determined in good faith by our Board of Directors 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 our Board of Directors. Typically there is not a public market for the securities of the privately held companies in which we have invested and will generally continue to invest. As a result, we value these securities quarterly at fair value as determined in good faith by our Board of Directors based on input from management, a nationally recognized independent advisor (on a rotational basis) and our audit committee. See “Business—Valuation Process and Determination of Net Asset Value” for a more detailed description of our valuation process.

The determination of fair value and consequently, the amount of unrealized gains and losses in our portfolio, is to a certain degree subjective and dependent on the judgment of our Board. Certain factors that may be considered in determining the fair value of our investments include the nature and realizable value of any collateral, the portfolio company’s earnings and its ability to make payments on its indebtedness, the markets in which the portfolio company does business, comparison to comparable publicly-traded companies, discounted cash flows and other relevant factors. Because such valuations, and particularly valuations of private securities and private 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 upon the sale or disposition of 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 shares during a period in which the net asset value understates the value of our investments will receive a lower price for their shares than the value of our investments might warrant.

Volatility or a prolonged disruption in the credit markets could materially damage our business.

We are required to record our assets at fair value, as determined in good faith by our Board of Directors in accordance with our valuation policy. As a result, volatility in the capital markets may adversely affect our valuations and our net asset value, even if we intend to hold investments to maturity. Volatility or dislocation in the capital markets may depress our stock price below our net asset value per share and create a challenging environment in which to raise debt and equity capital. As a BDC, we are generally not able to issue additional shares of our common stock at a price less than net asset value without first obtaining approval for such issuance from our stockholders and our independent directors. Additionally, our ability to incur indebtedness (including by issuing preferred stock) is limited by applicable regulations such that our asset coverage under the 1940 Act must equal at least 200% of total indebtedness immediately after each time we incur indebtedness exclusive of the SBA debentures pursuant to our SEC exemptive relief. Shrinking portfolio values negatively impact our ability to borrow additional funds under our credit facility because our net asset value is reduced for purposes of the 200% asset leverage test. If the fair value of our assets declines substantially, we may fail to maintain the asset coverage ratio stipulated by the 1940 Act, which could, in turn, cause us to lose our status as a BDC and materially impair our business operations. A protracted disruption in the credit markets could also materially decrease demand for our investments.

The significant disruption in the capital markets experienced in the past had and may in the future have a negative effect on the valuations of our investments, and on the potential for liquidity events involving our investments. The debt capital that will be available to us in the future, if at all, is likely to have a higher cost and less favorable terms and conditions. If our financing costs increase and we have no increase in interest income, then our net investment income will decrease. A prolonged inability to raise capital will require us to reduce the volume of loans we originate and could have a material adverse impact on our business, financial condition or results of operations. This may also increase the probability that other structural risks negatively impact us. These situations may arise due to circumstances that we may be unable to control, such as a protracted disruption in the credit markets, a severe decline in the value of the U.S. dollar, a sharp economic downturn or an operational problem that affects third parties or us, and could materially damage our business.

We operate in a highly competitive market for investment opportunities.

A large number of entities compete with us to make the types of investments that we make in target companies. We compete for investments with other BDCs and investment funds (including private equity funds and mezzanine funds), as well as traditional financial services companies such as commercial and investment banks and other sources of funding. Moreover, alternative investment vehicles, such as hedge funds, also invest in lower middle market companies.

As a result, competition for investment opportunities in lower middle market companies is intense. 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 lower middle market 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 have greater experience operating under, or are not subject to, the regulatory restrictions that the 1940 Act imposes on us as a BDC.

##### Table of Contents

We are dependent upon our executives for our future success.

We depend on the members of our senior management team, particularly executive officers Garland S. Tucker, III, Brent P.W. Burgess and Steven C. Lilly, for the final selection, structuring, closing and monitoring of our investments. These executive officers have critical industry experience and relationships that we rely on to implement our business plan. If 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.

We experience competition in attracting and retaining qualified personnel, particularly investment professionals, and we may be unable to maintain or grow our business if we cannot attract and retain such personnel. 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 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 could 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 and investment teams will maintain their relationships with financial institutions, private equity and other non-bank investors, investment bankers, commercial bankers, attorneys, accountants and consultants, and we will rely to a significant extent upon these relationships to provide us with potential investment opportunities. If our management and investment teams fail to maintain their existing relationships or develop new relationships with other sponsors or sources of investment opportunities, we will not be able to grow our investment portfolio. In addition, individuals with whom members of our management and investment teams 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.

Because of the limited amount of committed funding under our credit facility, we will have limited ability to fund new investments if we are unable to expand the facility.

On May 9, 2011, we entered into a credit agreement providing for a revolving line of credit, which we refer to as the Credit Facility. Committed funding under the Credit Facility was $75.0 million as of March 31, 2012. The Credit Facility has an accordion feature which allows for an increase in the total loan size up to $90.0 million. However, if we are unable to meet the terms of the accordion feature, we will be unable to expand the Credit Facility and thus will continue to have limited availability to finance new investments under our line of credit. The Credit Facility matures on May 8, 2014, with one remaining one-year extension option bringing the total potential commitment and funding period to four years from the time we closed on the Credit Facility. If the facility is not renewed or extended, all principal and interest will be due and payable.

##### Table of Contents

There can be no guarantee that we will be able to renew, extend or replace the Credit Facility upon its maturity on terms that are favorable to us, if at all. Our ability to expand the Credit Facility, and to obtain replacement financing at the time of maturity, will be constrained by then-current economic conditions affecting the credit markets. In the event that we are not able to expand the Credit Facility, or to renew, extend or refinance the Credit Facility at the time of its maturity, this could have a material adverse effect on our liquidity and ability to fund new investments, our ability to make distributions to our stockholders and our ability to qualify as a RIC under the Code.

Regulations governing our operation as a business development company 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. Currently we, through our SBIC subsidiaries, issue debt securities guaranteed by the SBA. In the future, we may issue debt securities or preferred stock and/or borrow money from banks or other financial institutions (including borrowings under our line of credit), which we refer to collectively as senior securities. As a result of issuing senior securities, we will be exposed to additional risks, including, but not limited to, 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% 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. Further, we 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 distributions 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, 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.

Additional Common Stock. Under the provisions of the 1940 Act, 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 in the best interests of our stockholders, and our stockholders approve such sale. At our Annual Stockholders Meeting on May 2, 2012, our stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. Our

##### Table of Contents

stockholders did not specify a maximum discount below net asset value at which we are able to sell or otherwise issue our common stock; however, we do not intend to sell or otherwise issue shares of our common stock below net asset value unless our Board of Directors determines that it would be in our stockholders’ best interests to do so. In any such case, however, the price at which our common stock 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 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. 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.

In addition to regulatory limitations on our ability to raise capital, our line of credit contains various covenants, which, if not complied with, could accelerate our repayment obligations under the facility, thereby materially and adversely affecting our liquidity, financial condition, results of operations and ability to pay distributions.

We will have a continuing need for capital to finance our loans. We are party to the Credit Facility, which provides us with a revolving credit line facility of up to $90.0 million, of which $75.0 million was available for borrowings as of March 31, 2012. The Credit Facility contains customary terms and conditions, including, without limitation, affirmative and negative covenants such as information reporting requirements, minimum consolidated tangible net worth, minimum interest coverage ratio, maintenance of RIC and BDC status, and minimum liquidity. The Credit Facility also contains customary events of default with customary cure and notice, including, without limitation, nonpayment, misrepresentation of representations and warranties in a material respect, breach of covenant, cross-default to other indebtedness, bankruptcy, change of control, and materially adverse effect. The Credit Facility permits us to fund additional loans and investments as long as we are within the conditions set out in the credit agreement. Our continued compliance with these covenants depends on many factors, some of which are beyond our control, and there are no assurances that we will continue to comply with these covenants. Our failure to satisfy these covenants could result in foreclosure by our lenders, which would accelerate our repayment obligations under the facility and thereby have a material adverse effect on our business, liquidity, financial condition, results of operations and ability to pay distributions to our stockholders.

Recent healthcare reform legislation may affect our revenue and financial condition.

On March 23, 2010, the President of the United States signed into law the Patient Protection and Affordable Care Act of 2010 and on March 30, 2010, the President signed into law the Health Care and Education Reconciliation Act, which in part modified the Patient Protection and Affordable Care Act. Together, the two Acts serve as the primary vehicle for comprehensive health care reform in the United States. The Acts are intended to reduce the number of individuals in the United States without health insurance and effect significant other changes to the ways in which health care is organized, delivered and reimbursed. The complexities and ramifications of the new legislation are significant, and will be implemented in a phased approach beginning in 2010 and concluding in 2018. At this time, the effects of health care reform and its impact on our operations and on the business, revenues and financial condition of our portfolio companies are not yet known. Accordingly, the reform could adversely affect the cost of providing healthcare coverage generally and could adversely affect the financial success of both the portfolio companies in which we invest and us.

The impact of recent financial reform legislation on us is uncertain.

In light of current conditions in the U.S. and global financial markets and the U.S. and global economy, legislators, the presidential administration and regulators have increased their focus on the regulation of the financial services industry. The Dodd-Frank Reform Act became effective on July 21, 2010; however, many provisions of the Dodd-Frank Reform Act have delayed effectiveness or will not become effective until the

20

##### Table of Contents

relevant federal agencies issue new rules to implement the Dodd-Frank Reform Act. Nevertheless, the Dodd-Frank Reform Act may have a material adverse impact on the financial services industry as a whole and on our business, results of operations and financial condition. Accordingly, we cannot predict the effect the Dodd-Frank Reform Act or its implementing regulations will have on our business, results of operations or financial condition.

Our SBIC subsidiaries are licensed by the SBA, and therefore subject to SBA regulations.

Our SBIC subsidiaries are licensed to act as SBICs and are regulated by the SBA. Pursuant to SBA regulations, an SBIC can provide financing in the form of debt, debt with equity features and/or equity to “eligible” small businesses. 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. See “Regulation — Small Business Administration Regulations” for more discussion on these limitations. Compliance with SBA requirements may cause our SBIC subsidiaries, and us, as their parent, to forego attractive investment opportunities that are not permitted under SBA regulations.

Further, the SBA regulations require that a licensed SBIC be periodically examined and audited by the SBA to determine its 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 10.0% or more of a class of capital stock of a licensed SBIC. If our SBIC subsidiaries fail to comply with applicable SBA regulations, the SBA could, depending on the severity of the violation, limit or prohibit our SBIC subsidiaries’ use of debentures, declare outstanding debentures immediately due and payable, and/or limit our SBIC subsidiaries from making new investments. In addition, the SBA can remove the general partners of our SBIC subsidiaries and have a receiver appointed, or 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, as amended, or any rule or regulation promulgated thereunder. Such actions by the SBA would, in turn, negatively affect us because our SBIC subsidiaries are wholly owned.

Because we borrow money and may in the future issue additional senior securities including preferred stock and debt securities, 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 gain or loss on invested equity capital. As we use leverage to partially finance our investments, you will experience increased risks associated with investing in our securities. We currently borrow under our Credit Facility and have issued senior securities, and in the future may borrow from, or issue additional senior securities to, banks, insurance companies, funds, institutional investors and other lenders and investors. Our SBIC subsidiaries 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 our SBIC subsidiaries that are superior to the claims of our common stockholders. In addition, our Credit Facility contains financial and operating covenants that could restrict our business activities, including our ability to declare dividends if we default under certain provisions. Breach of any of those covenants could cause a default under those instruments. Such a default, if not cured or waived, could have a material adverse effect on us. We may also borrow from banks and other lenders or issue additional senior securities including preferred stock and debt securities in the future. If the value of our assets increases, then leveraging would cause the net asset value attributable to our common stock to increase more sharply than it would have had we not leveraged. Conversely, 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. Similarly, any increase in our income in excess of interest payable on the borrowed funds would cause our net investment income to increase more than it would without the leverage, while any decrease in our income would cause our net investment income to decline more sharply than it would have had we not borrowed. Such a decline could negatively affect our ability to make distributions to our stockholders. Leverage is generally considered a speculative investment technique.

##### Table of Contents

As a BDC, we are generally required to meet a coverage ratio of total assets to total borrowings and other senior securities, which include all of our borrowings (other than SBA leverage) and any preferred stock we may issue in the future, of at least 200%. If this ratio declines below 200%, we may not be able to incur additional debt and may need to sell a portion of our investments to repay some debt when it is disadvantageous to do so, and we may not be able to make distributions.

On March 31, 2012, we had $213.9 million of outstanding indebtedness guaranteed by the SBA, which had a weighted average annualized interest cost of 4.76%. As of March 31, 2012, all SBA debentures have been pooled.

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 higher or lower than those appearing below.

|  | Assumed Return on our Portfolio (Net of Expenses) |
|  |  | (10.0 | )% |  |  | (5.0 | )% |  |  | 0.0 | % |  |  | 5.0 | % |  |  | 10.0 | %
Corresponding net return to stockholder(1) |  |  | (20.6) | % |  |  | (12.1) | % |  |  | (3.6) | % |  |  | 4.8 | % |  |  | 13.3 | %

(1) | Assumes $698.7 million in total assets, $282.9 million in debt outstanding, $412.1 million in net assets and an average cost of funds of 5.31%, which was the weighted average borrowing cost on our borrowings at March 31, 2012.

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

Funding a portion of our investments with preferred stock, magnifies the potential for gain or loss and the risks of investing in us in the same way as our other borrowings.

Preferred stock, which is another form of leverage, has the same risks to our common stockholders as borrowings because the dividends on any preferred stock must be cumulative. Payment of such dividends and repayment of the liquidation preference of such preferred stock must take preference over any dividends or other payments to our common stockholders, and preferred stockholders 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.

SBA regulations limit the outstanding dollar amount of SBA guaranteed debentures that may be issued by an SBIC or group of SBICs under common control.

The SBA regulations currently limit the dollar amount of SBA-guaranteed debentures that can be issued by any one SBIC to $150.0 million or to a group of SBICs under common control to $225.0 million. Moreover, an SBIC may not borrow an amount in excess of two times (and in certain cases, up to three times) its regulatory capital. As of March 31, 2012, Triangle SBIC had issued $139.6 million in face amount of SBA-guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of March 31, 2012, Triangle SBIC II had issued $75.0 million in face amount of SBA-guaranteed debentures. During times that we reach the maximum dollar amount of SBA-guaranteed debentures permitted, and if we require additional capital, our cost of capital is likely to increase, and there is no assurance that we will be able to obtain additional financing on acceptable terms.

Moreover, the current status of our SBIC subsidiaries as SBICs does not automatically assure that our SBIC subsidiaries will continue to receive SBA-guaranteed debenture funding. Receipt of SBA leverage funding is

22

##### Table of Contents

dependent upon our SBIC subsidiaries continuing to be in compliance with SBA regulations and policies and available SBA funding. The amount of SBA leverage funding available to SBICs is dependent upon annual Congressional authorizations and in the future may be subject to annual Congressional appropriations. There can be no assurance that there will be sufficient debenture funding available at the times desired by our SBIC subsidiaries.

The debentures guaranteed by the SBA have a maturity of ten years and require semi-annual payments of interest. Our SBIC subsidiaries will need to generate sufficient cash flow to make required interest payments on the debentures. If our SBIC subsidiaries are unable to meet their financial obligations under the debentures, the SBA, as a creditor, will have a superior claim to our SBIC subsidiaries’ assets over our stockholders in the event we liquidate our SBIC subsidiaries or the SBA exercises its remedies under such debentures as the result of a default by us. In addition, the SBA must approve our independent directors before our SBIC subsidiaries will be permitted to issue additional debentures guaranteed by the SBA.

We may experience fluctuations in our quarterly results.

We could experience fluctuations in our quarterly 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 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, results for any period should not be relied upon as being indicative of performance in future periods.

Our ability to enter into and exit investment transactions with our affiliates will be restricted.

Except in those instances where we have received prior exemptive relief from the SEC, we will be prohibited under the 1940 Act from knowingly participating in certain transactions with our affiliates without the prior approval of our independent directors. Any person that owns, directly or indirectly, 5.0% or more of our outstanding voting securities is deemed our affiliate for purposes of the 1940 Act and we are generally prohibited from buying or selling any security from or to such affiliate, absent the prior approval of our independent directors. The 1940 Act also prohibits “joint” transactions with an affiliate, which could include investments in the same portfolio company (whether at the same or different times), without prior approval of our independent directors. If a person acquires more than 25.0% of our voting securities, we will be prohibited from buying or selling any security from or to such person, or entering into joint transactions with such person, absent the prior approval of the SEC. These restrictions could limit or prohibit us from making certain attractive investments that we might otherwise make absent such restrictions.

Our Board of Directors may change our investment objective, 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 investment objective, operating policies and strategies without prior notice and without stockholder approval (except as required by the 1940 Act). However, absent stockholder approval, we may not change the nature of our business so as to cease to be, or withdraw our election as, a BDC. 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 you distributions and cause you to lose all or part of your investment. Moreover, we will have significant flexibility in investing the net proceeds from any future offering and may use the net proceeds from such offerings in ways with which investors may not agree or for purposes other than those contemplated at the time of the offering.

##### Table of Contents

We will be subject to corporate-level U.S. federal income tax if we are unable to maintain our status as a regulated investment company under Subchapter M of the Code, which will adversely affect our results of operations and financial condition.

We have elected to be treated as a RIC under the Code, which generally will allow us to avoid being subject to corporate-level U.S. federal income tax. To obtain and 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 90.0% of our net ordinary income and net short-term capital gain in excess of net long-term capital loss, if any. We will be subject to a 4.0% nondeductible U.S. federal excise tax, however, to the extent that we do not satisfy certain additional minimum distribution requirements on a calendar year basis. 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 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 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 illiquid, any such dispositions could be made at disadvantageous prices and could result in substantial losses.

If we fail to qualify for or maintain RIC tax treatment for any reason and are subject to corporate-level U.S. federal 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 also be subject to certain U.S. federal excise taxes, as well as state, local and foreign taxes.

We may not be able to pay you distributions, our distributions may not grow over time, a portion of distributions paid to you may be a return of capital, and investors in our debt securities may not receive all of the interest income to which they are entitled.

We intend to pay quarterly 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 make a specified level of cash distributions or year-to-year increases in cash distributions. Our ability to pay distributions might be harmed by, among other things, the risk factors described in this prospectus. In addition, the inability to satisfy the asset coverage test applicable to us as a BDC could, in the future, 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, our SBIC subsidiaries’ compliance with applicable SBIC regulations and such other factors as our Board of Directors may deem relevant from time to time. In addition, our line of credit may restrict the amount of distributions we are permitted to make. We cannot assure you that we will pay distributions to our stockholders in the future.

24

##### Table of Contents

The above-referenced restrictions on distributions may also inhibit our ability to make required interest payments to holders of our debt securities, which may cause a default under the terms of our debt agreements. Such a default could materially increase our cost of raising capital, as well as cause us to incur penalties under the terms of our debt agreements.

When we make quarterly distributions, we will be required to determine the extent to which such distributions are paid out of current or accumulated earnings and profits, recognized capital gain or capital. To the extent there is a return of capital, investors will be required to reduce their basis in our stock for federal income tax purposes.

We may have difficulty paying our required distributions if we recognize income before or without receiving cash representing such income.

For U.S. federal income tax purposes, we may be required to recognize taxable income in circumstances in which we do not receive a corresponding payment in cash. For example, if we hold debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments with PIK interest or, in certain cases, increasing interest rates or debt instruments that were issued with warrants), 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 deferred loan origination fees that are paid after origination of the loan or are paid in non-cash compensation such as warrants or stock. We anticipate that a portion of our income may constitute original issue discount or other income required to be included in taxable income prior to receipt of cash. Further, we may elect to amortize market discounts and include such amounts in our taxable income in the current year, instead of upon disposition, as an election not to do so would limit our ability to deduct interest expenses for U.S. federal income tax purposes.

Because any original issue discount or other amounts accrued will be included in our investment company taxable income for the year of the 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. As a result, we may have difficulty meeting the annual distribution requirement necessary to obtain and maintain RIC tax treatment under the Code. 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, see “Material U.S. Federal Income Tax Considerations — Taxation as a RIC.”

You may have a current tax liability on distributions you elect to reinvest in our common stock but would not receive cash from such distributions to pay such tax liability.

If you participate in our dividend reinvestment plan, you will be deemed to have received, and for U.S. federal income tax purposes will be taxed on, the amount reinvested in our common stock to the extent the amount reinvested was not a tax-free return of capital. As a result, unless you are a tax-exempt entity, you may have to use funds from other sources to pay your tax liability on the value of our common stock received from the distribution.

Our SBIC subsidiaries, as SBICs, 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.

In order for us to continue to qualify as a RIC, we will be required to distribute on an annual basis substantially all of our taxable income, including income from our subsidiaries, including our SBIC subsidiaries. As the majority of our investments are generally held by our SBIC subsidiaries, we will be substantially dependent on our SBIC subsidiaries for cash distributions to enable us to meet the RIC distribution requirements.

25

##### Table of Contents

Our SBIC subsidiaries may be limited by the Small Business Investment Act of 1958, and SBA regulations governing SBICs, from making certain distributions to us that may be necessary to enable us to qualify as a RIC. We may have to request a waiver of the SBA’s restrictions for our SBIC subsidiaries to make certain distributions to maintain our status as a RIC. We cannot assure you that the SBA will grant such waiver and if our SBIC subsidiaries are unable to obtain a waiver, compliance with the SBA regulations may result in loss of RIC status and a consequent imposition of corporate-level U.S. federal income tax on us.

Pursuant to SBA regulations, an SBIC with outstanding debenture leverage may only distribute cumulative realized profits (less unrealized losses on investments). It may not return more than 2% of its outstanding capital in any fiscal year without SBA prior approval. Historically, SBA has permitted payment in excess of 2% only pursuant to an approved wind up plan filed by the SBIC pursuant to which SBA determines that repayment of outstanding debentures is adequately assured.

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 and make distributions.

In order to satisfy the requirements applicable to a RIC and to avoid payment of U.S. federal excise tax, we intend to distribute to our stockholders substantially all of our net ordinary income and net capital gain income except for certain net long-term capital gains recognized after we became a RIC, some or all of which we may retain, pay applicable U.S. federal income taxes with respect thereto, and elect to treat as deemed distributions to our stockholders. As a BDC, we generally are required to meet a coverage ratio of total assets to total senior securities, which includes all of our borrowings (other than SBA leverage) and any preferred stock we may issue in the future, of at least 200.0%. This requirement limits the amount that we may borrow and may prohibit us from making distributions. 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 or sell additional securities and, depending on the nature of our leverage, to repay a portion of our indebtedness at a time when such sales may be disadvantageous. In addition, issuance of additional securities could dilute the percentage ownership of our current stockholders in us.

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. 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. In addition, as a BDC, we generally are not permitted to issue equity securities priced below net asset value without stockholder approval. At our Annual Stockholders Meeting on May 2, 2012, our stockholders voted to allow us to issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. Our stockholders did not specify a maximum discount below net asset value at which we are able to issue our common stock; however, we do not intend to issue shares of our common stock below net asset value unless our Board of Directors determines that it would be in our stockholders’ best interests to do so. For an illustration on the potential dilutive effect of an offering of our common stock at a price below net asset value, please see the illustration below.

Illustration: Examples of Dilutive Effect of the Issuance of Shares Below Net Asset Value. The following table illustrates the level of net asset value dilution that would be experienced by a nonparticipating stockholder in three different hypothetical offerings of different sizes and levels of discount from net asset value per share, although it is not possible to predict the level of market price decline that may occur. Actual sales prices and discounts may differ from the presentation below.

Assume that Company XYZ has 1,000,000 common shares outstanding, $15,000,000 in total assets and $5,000,000 in total liabilities. The current net asset value and net asset value per share are thus $10,000,000 and $10.00, respectively. The table illustrates the dilutive effect on nonparticipating Stockholder A of (1) an offering

26

##### Table of Contents

of 50,000 shares (5% of the outstanding shares) at $9.50 per share after offering expenses and commission (a 5% discount from net asset value), (2) an offering of 100,000 shares (10% of the outstanding shares) at $9.00 per share after offering expenses and commissions (a 10% discount from net asset value) and (3) an offering of 200,000 shares (20% of the outstanding shares) at $8.00 per share after offering expenses and commissions (a 20% discount from net asset value). The acronym “NAV” stands for “net asset value.”

In any offering of common stock, we will present the actual dilution to stockholders in tabular form in the prospectus supplement specific to that offering.

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

We, our SBIC subsidiaries, and our portfolio companies will be subject to regulation at the local, state and federal level. 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 program could have a significant impact on our ability to obtain lower-cost leverage and, therefore, our competitive advantage over 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 in this prospectus and may result in our investment focus shifting from the areas of expertise of our management team to other types of investments in which our management 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.

Efforts to comply with the Sarbanes-Oxley Act will involve significant expenditures, and non-compliance with the Sarbanes-Oxley Act may adversely affect us.

We are subject to the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the related rules and regulations promulgated by the SEC. Among other requirements, under Section 404 of the Sarbanes-Oxley Act and rules and regulations of the SEC thereunder, our management is required to report on our internal controls over financial reporting. We are required to review on an annual basis our internal controls over financial reporting, and on a quarterly and annual basis to evaluate and disclose significant changes in our internal controls over financial reporting. We have and expect to continue to incur significant expenses related to compliance with the Sarbanes-Oxley Act, which will negatively impact our financial performance and our ability to make distributions. In addition, this process results in a diversion of management’s time and attention. Since we have a limited operating history as a company subject to the Sarbanes-Oxley Act, we cannot assure you that our internal controls over financial reporting will continue to be effective. In the event that we are unable to maintain compliance with the Sarbanes-Oxley Act and related rules, we may be adversely affected.

The Credit Facility with a potential member of the underwriting syndicate may not be as favorable to us as if it had been negotiated with an unaffiliated third-party.

We entered into the Credit Facility on May 9, 2011 with a lender that has acted and may in the future act as a member of the underwriting syndicate for securities issued pursuant to this registration statement. Consequently the terms may not be as favorable to us as if they had been negotiated with an unrelated third-party.

We could face losses and potential liability if intrusion, viruses or similar disruptions to our technology jeopardize our confidential information or that of users of our technology.

Although we have implemented, and will continue to implement, security measures, our technology platform is and will continue to be vulnerable to intrusion, computer viruses or similar disruptive problems caused by unauthorized users. The misappropriation of proprietary information could expose us to a risk of loss or litigation.

Risks Relating to Our Investments

Our investments in portfolio companies may be risky, and we could lose all or part of our investment.

Investing in lower middle market companies involves a number of significant risks. Among other things, these companies:

| • |  | may have limited financial resources to meet future capital needs and thus may be unable to grow or 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 more significant customer concentration 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 or termination of one or more of these persons could have a material adverse impact on our portfolio company and, in turn, on us;

28

##### Table of Contents

| • |  | 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 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.

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

We invest, and will continue to 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 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 and certain SBA diversification requirements for our investments held by our two wholly-owned SBIC subsidiaries, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio companies.

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 exercise of a warrant to purchase common stock. 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 or may reduce the expected yield on the investment.

##### Table of Contents

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

We invest primarily in senior secured debt and subordinated notes as well as equity issued by lower middle market companies. Our portfolio companies may have, or may be permitted to incur, other debt, or issue other securities that rank equally with, or senior to, the debt in which we invest. By their terms, such instruments may entitle the holders to receive payment of dividends, 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 securities 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 holders, such portfolio company may not have any remaining assets to use for repaying its obligation to us. In the case of securities ranking equally with our investments, we would have to share on an equal basis any distributions with other security holders in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company.

The rights we may have with respect to the collateral securing any junior priority loans we make to our portfolio companies may also be limited pursuant to the terms of one or more intercreditor agreements that we enter into with the holders of senior debt. Under such an intercreditor agreement, at any time that senior obligations are outstanding, we may forfeit certain rights with respect to the collateral to the holders of the senior obligations. These rights may include the right to commence enforcement proceedings against the collateral, the right to control the conduct of such enforcement proceedings, the right to approve amendments to collateral documents, the right to release liens on the collateral and the right to waive past defaults under collateral documents. We may not have the ability to control or direct such actions, even if as a result our rights as junior lenders are adversely affected.

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 senior 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’s 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

30

##### Table of Contents

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.

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 second priority liens after payment in full of all obligations secured by the senior lender’s first priority liens on the collateral. There is also a risk that such collateral securing our investments may decrease in value over time, may be difficult to sell in a timely manner, may be difficult to appraise and may 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.

If we do not invest a sufficient portion of our assets in qualifying assets, we could fail to qualify as a business development company or be precluded from investing according to our current business strategy.

As a BDC, we may not acquire any assets other than “qualifying assets” unless, at the time of and after giving effect to such acquisition, at least 70.0% of our total assets are qualifying assets. For further detail, see “Regulation.”

We believe that substantially all of our investments are qualifying assets. However, we may be precluded from investing in what we believe are attractive investments if such investments are not qualifying assets for purposes of the 1940 Act. If we do not invest a sufficient portion of our assets in qualifying assets, we could lose our status as a BDC, which would have a material adverse effect on our business, financial condition and results of operations. Similarly, these rules could prevent us from making follow-on investments in existing portfolio companies (which could result in the dilution of our position).

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.

Beyond our RIC asset diversification requirements and certain SBA diversification requirements for our investments held by our two wholly-owned SBIC subsidiaries, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio companies.

We generally will not control our portfolio companies.

We do not, and do not expect to, control most 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 may make business decisions with which we disagree and the management of such company, as representatives of the holders of their common equity, may take risks or otherwise act in ways that do not serve our interests as debt investors. 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 could decrease the value of our portfolio holdings.

Economic recessions or downturns could impair our portfolio companies and harm our operating results.

Beginning in the third quarter of 2007, global credit and other financial markets began to suffer substantial stress, volatility, illiquidity and disruption. These forces reached extraordinary levels in late 2008, resulting in the bankruptcy of, the acquisition of, or government intervention in the affairs of several major domestic and international financial institutions. In particular, the financial services sector was negatively impacted by significant write-offs as the value of the assets held by financial firms declined, impairing their capital positions and abilities to lend and invest. We believe that such value declines were exacerbated by widespread forced liquidations as leveraged holders of financial assets, faced with declining prices, were compelled to sell to meet margin requirements and maintain compliance with applicable capital standards. Such forced liquidations also impaired or eliminated many investors and investment vehicles, leading to a decline in the supply of capital for investment and depressed pricing levels for many assets. These events significantly diminished overall confidence in the debt and equity markets, engendered unprecedented declines in the values of certain assets, and caused extreme economic uncertainty.

Since March 2009, there have been signs that the global credit and other financial market conditions have improved as stability has increased throughout the international financial system and many public stock market indices have experienced positive total returns. Concentrated policy initiatives undertaken by central banks and governments appear to have curtailed the incidence of large-scale failures within the global financial system. Concurrently, investor confidence, financial indicators, capital markets activity and asset prices have shown signs of marked improvement since the second quarter of 2009. However, while financial conditions have improved, domestic unemployment rates remain high, and economic activity remains subdued. In addition, there are early signs that many businesses and industries are experiencing inflationary pressures both internationally and domestically.

Many of our current and/or future portfolio companies may be susceptible to economic slowdowns or recessions and may be unable to repay our debt investments during these periods. Therefore, during such slowdowns or recessions, our non-performing assets are likely to increase, and the value of our portfolio is likely to decrease. Adverse economic conditions may also decrease the value of any collateral securing some of our debt investments and the value of our equity investments. A prolonged economic slowdown or recession may further decrease the value of such collateral and result in losses of value in our portfolio and a decrease in investment income, net investment income, assets, and net worth. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us on terms we deem acceptable. These events could prevent us from increasing investment originations and harm our operating results.

Financial results may be affected adversely if one or more of our portfolio investments defaults on its loans or fails to perform as we expect.

Our portfolio consists primarily of debt and equity investments in privately owned middle-market businesses. Compared to larger publicly owned companies, these middle-market companies may be in a weaker financial position and experience wider variations in their operating results, which may make them more vulnerable to economic downturns. Typically, these companies need more capital to compete; however, their access to capital is limited and their cost of capital is often higher than that of their competitors. Our portfolio companies face intense competition from larger companies with greater financial, technical and marketing resources and their success typically depends on the management talents and efforts of an individual or a small group of persons. The loss of any of their key employees could affect their ability to compete effectively and harm their financial condition. Further, some of these companies conduct business in regulated industries that are susceptible to regulatory changes. These factors could impair the cash flow of our portfolio companies and result in other events, such as bankruptcy. These events could limit a portfolio company’s ability to repay their obligations to us, which may have an adverse affect on the return on, or the recovery of, our investment in these businesses. Deterioration in a borrower’s financial condition and prospects may be accompanied by deterioration in the value of the loan’s collateral.

32

##### Table of Contents

Some of these companies cannot obtain financing from public capital markets or from traditional credit sources, such as commercial banks. Accordingly, loans made to these types of companies pose a higher default risk, than loans made to companies who have access to traditional credit sources.

Generally, little, if any, public information is available about such companies. Therefore, we must rely on our employees’ diligence to obtain the information needed, such as the financial information of these companies, to make well-informed investment decisions. If we do not uncover material information about these companies, we may not make a fully informed investment decision, which could, in turn cause us to lose money on our investments.

Potential writedowns or losses with respect to portfolio investments existing and to be made in the future could adversely affect our results of operations, cash flows, dividend level, net asset value and stock price.

As of March 31, 2012, the fair value of our non-accrual assets was approximately $2.2 million, which comprised approximately 0.4% of the total fair value of our portfolio. The fair value of these non-accrual assets was less than cost as of March 31, 2012. We also had one asset as of March 31, 2012 that was on non-accrual with respect to the PIK interest component of the loan. The fair value of this asset as of March 31, 2012 was approximately $5.2 million, which comprised approximately 1.0% of the total fair value of our portfolio. In addition, as of March 31, 2012, we had, on a fair value basis, approximately $23.8 million of debt investments or 4.4% of the total fair value of our portfolio, which were current with respect to scheduled interest and principal payments, but which were carried at less than cost. In light of current economic conditions, certain of our portfolio companies may be unable to service our debt investments on a timely basis. These conditions may also decrease the value of collateral securing some of our debt investments, as well as the value of our equity investments. As a result, the number of non-performing assets in our portfolio may increase, and the overall value of our portfolio may decrease, which could lead to financial losses in our portfolio and a decrease in our investment income, net investment income, dividends and assets.

Any unrealized losses we experience on our loan portfolio may be an indication of future realized losses, which could reduce our income 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 losses in our loan portfolio could be an indication of a portfolio company’s inability to meet its repayment obligations to us with respect to the affected loans. This could result in realized losses in the future and ultimately in reductions of our income available for distribution in future periods.

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 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.

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

33

##### Table of Contents

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 and net investment income.

Most of our debt investments will bear interest at fixed rates, and the value of these investments could be negatively affected by increases in market interest rates. In addition, an increase in interest rates would make it more expensive to use debt to finance our investments. As a result, a significant increase in market interest rates could both reduce the value of our portfolio investments and increase our cost of capital, which would reduce our net investment income. Also, an increase in interest rates available to investors could make an investment in our common stock less attractive if we are not able to increase our distribution rate, a situation which could reduce the value of our common stock. Conversely, a decrease in interest rates may have an adverse impact on our returns by requiring us to seek 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.

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 co-investments in companies in conjunction with private equity sponsors. 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. We may be unable to exercise these puts rights for the consideration provided in our investment documents if the issuer is in financial distress.

Risks Relating to an Offering of Our Securities

We may be unable to invest a significant portion of the net proceeds raised from our offerings on acceptable terms, which would harm our financial condition and operating results.

Delays in investing the net proceeds raised in our offerings 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 from any offering 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, it may take a substantial period of time to invest substantially all of the net proceeds of any offering in securities meeting our investment objective. During such a period, we have and will continue to invest the net proceeds of any offering primarily in cash, cash equivalents, U.S. government securities, repurchase agreements and high-quality debt instruments maturing in one year or less from the time of investment, which may produce returns that are significantly lower than the returns which

34

##### Table of Contents

we expect to achieve when our portfolio is fully invested in securities meeting our investment objective, and given our expense ratio and the prevailing interest rate climate, there is a possible risk of losing money on the offering proceeds of certain securities, such as debt securities during this interval. As a result, any dividends or distributions that we pay during such period may be substantially lower than the dividends or 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 are invested in securities meeting our investment objective, the market price for our securities may decline. Thus, the return on your investment may be lower than when, if ever, our portfolio is fully invested in securities meeting our investment objective.

In addition, the SBA limits our SBIC subsidiaries, Triangle SBIC and Triangle SBIC II, to investing idle funds in the following types of securities:

| • |  | 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;

| • |  | 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);

| • |  | certificates of deposit with a maturity of one year or less, issued by a federally insured institution; or

| • |  | a deposit account in a federally insured institution that is subject to withdrawal restriction of one year or less.

Shares of closed-end investment companies, including business development companies, frequently trade at a discount to their net asset value.

Shares of closed-end investment companies, including BDCs, frequently trade at a discount from 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 net asset value, we will generally not be able to issue additional common stock at the market price without first obtaining the approval of our stockholders and our independent directors. On May 2, 2012 our stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. Our stockholders did not specify a maximum discount below net asset value at which we are able to sell or otherwise issue our common stock; however, we do not intend to sell or otherwise issue shares of our common stock below net asset value unless our Board of Directors determines that it would be in our stockholders’ best interests to do so.

Recent conditions may increase the risks associated with our business and an investment in us.

Beginning in the third quarter of 2007, the U.S. economy and financial markets began experiencing a high level of volatility, disruption and stress, which was exacerbated by the failure of several major financial institutions in the last few months of 2008. In addition, the U.S. economy entered a recession, which was severe and prolonged. Similar conditions occurred in the financial markets and economies of numerous other countries and could worsen, both in the U.S. and globally. These conditions raised the level of many of the risks described herein and, if repeated or continued, could have an adverse effect on our portfolio companies and on their results of operations, financial conditions, access to credit and capital. The stress in the credit market and upon banks has led other creditors to tighten credit and the terms of credit. In certain cases, senior lenders to our customers can block payments by our customers in respect of our loans to such customers. In turn, these could have adverse effects on our business, financial condition, results of operations, dividend payments, access to capital, valuation of our assets and our stock price. Notwithstanding recent gains across both the equity and debt markets, these conditions may continue for a prolonged period of time or worsen in the future.

##### Table of Contents

If, in the future, we sell common stock at a discount to our net asset value per share, stockholders who do not participate in such sale will experience immediate dilution in an amount that may be material.

On May 2, 2012, our stockholders approved our ability to sell or otherwise issue an unlimited number of shares of our common stock at any level of discount from net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. If we sell or otherwise issue shares of our common stock at a discount to net asset value, it will pose a risk of dilution to our stockholders. In particular, stockholders who do not purchase additional shares at or below the discounted price in proportion to their current ownership will experience an immediate decrease in net asset value per share (as well as in the aggregate net asset value of their shares if they do not participate at all). These stockholders will also experience a disproportionately greater decrease in their participation in our earnings and assets and their voting power than the increase we experience in our assets, potential earning power and voting interests from such issuances or sale. In addition, such issuances or sales may adversely affect the price at which our common stock trades. For additional information and hypothetical examples of these risks, see “Sales of Common Stock Below Net Asset Value,” and for actual dilution illustrations specific to an offering, see the prospectus supplement pursuant to which such sale is made.

Our net asset value may have changed significantly since our last valuation.

Our Board of Directors determines the fair value of our portfolio investments on a quarterly basis based on input from management, our audit committee and, as to certain of our investments, a third party independent valuation firm. While the Board of Directors will review our net asset value per share in connection with any offering, it will not always have the benefit of input from the independent valuation firm when it does so. Moreover, our financial statements have not been audited by our independent registered public accounting firm for any periods since December 31, 2011. The fair value of various individual investments in our portfolio and/or the aggregate fair value of our investments may change significantly over time. If the fair value of our investment portfolio at December 31, 2012 is less than the fair value at the time of an offering during 2012, then we may record an unrealized loss on our investment portfolio and may report a lower net asset value per share than will be reflected in the Selected Condensed Financial Data and the financial statements included in the prospectus supplement of that offering. If the fair value of our investment portfolio at December 31, 2012 is greater than the fair value at the time of an offering during 2012, we may record an unrealized gain on our investment portfolio and may report a greater net asset value per share than so reflected in the prospectus supplement of that offering. Upon publication of this information in connection with our announcement of operating results for our fiscal year ended December 31, 2012, the market price of our common stock may fluctuate materially, and may be substantially less than the price per share you pay for our common stock in an offering.

Investing in our securities may involve an above average 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 may be highly speculative, and therefore, an investment in our shares 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 shares may adversely affect the liquidity of the trading market for our shares and, if we seek to raise capital through future equity financings, our ability to raise such equity 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;

36

##### Table of Contents

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

| • |  | inability to obtain certain exemptive relief from the SEC;

| • |  | loss of RIC status or either of our SBIC subsidiaries’ status as an SBIC;

| • |  | changes in earnings or variations in operating results;

| • |  | changes in the value of our portfolio of investments;

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

| • |  | conversion features of subscription rights, warrants or convertible debt;

| • |  | 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.

As illustrated by recent events in the market for subprime loans, and mortgage securities generally, the market for any security is subject to volatility. The loans and securities purchased by us and issued by us are no exception to this fundamental investment truism that prices will fluctuate, although we lack any material exposure to the subprime and mortgage markets.

If a substantial number of shares become available for sale and are sold in a short period of time, the market price of our common stock could decline.

As of March 31, 2012, we had 27,263,151 shares of common stock outstanding. Sales of substantial amounts of our common stock, or the availability of shares for sale, including those offered hereby, could adversely affect the prevailing market price of our common stock. If this occurs and continues, it could impair our ability to raise additional capital through the sale of equity securities should we desire to do so.

Provisions of the Maryland General Corporation Law and our charter 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 charter 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. Specifically, our Board of Directors may adopt resolutions to classify our Board of Directors so that stockholders do not elect every director on an annual basis. Also, our charter provides that a director may be removed only for cause by the vote of at least two-thirds of the votes entitled to be cast for the election of directors generally. In addition, our bylaws provide that, subject to the satisfaction of certain procedural and informational requirements by the stockholders requesting the meeting, a special meeting of

37

##### Table of Contents

stockholders will be called by our secretary to act upon any matter that may properly be considered at a meeting of stockholders only upon the written request of the stockholders entitled to cast at least a majority of all the votes entitled to be cast on such matter at the meeting.

In addition, subject to the provisions of the 1940 Act, our charter permits our Board of Directors, without stockholder action, to authorize the issuance of shares of stock in one or more classes or series, including preferred stock. Subject to compliance with the 1940 Act, our Board of Directors may, without stockholder action, amend our charter from time to time to increase or decrease the number of shares of stock of any class or series that we have authority to issue. 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 shares of our common stock.

If we issue preferred stock and/or additional debt securities, the net asset value and market value of our common stock may become more volatile.

We cannot assure you that the issuance of preferred stock and/or additional debt securities would result in a higher yield or return to the holders of our common stock. The issuance of preferred stock and/or additional debt securities would likely cause the net asset value and market value of our common stock to become more volatile. If the dividend rate on the preferred stock, or the interest rate on the debt securities, were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of our common stock would be reduced. If the dividend rate on the preferred stock, or the interest rate on the debt securities, were to exceed the net rate of return on our portfolio, the use of leverage would result in a lower rate of return to the holders of common stock than if we had not issued the preferred stock or debt securities. Any decline in the net asset value of our investment would be borne entirely by the holders of our common stock. Therefore, if the market value of our portfolio were to decline, the leverage would result in a greater decrease in net asset value to the holders of our common stock than if we were not leveraged through the issuance of preferred stock. This decline in net asset value would also tend to cause a greater decline in the market price for our common stock.

There is also a risk that, in the event of a sharp decline in the value of our net assets, we would be in danger of failing to maintain required asset coverage ratios which may be required by the preferred stock and/or debt securities or of a downgrade in the ratings of the preferred stock and/or debt securities or our current investment income might not be sufficient to meet the dividend requirements on the preferred stock or the interest payments on the debt securities. In order to counteract such an event, we might need to liquidate investments in order to fund redemption of some or all of the preferred stock and/or debt securities. In addition, we would pay (and the holders of our common stock would bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred stock and/or debt securities. Holders of preferred stock and/or debt securities may have different interests than holders of common stock and may at times have disproportionate influence over our affairs. During the first quarter of 2012, we issued $69.0 million of 7.00% senior notes due 2019, to which the risks discussed above may apply.

If we issue auction rate p referred stock and you purchase such auction rate preferred stock, yo u may not be able to sell your auction rate p referred stock at an auction if the auction fails.

If we issue auction rate preferred stock and you purchase such auction rate preferred stock, you may not be able to sell your auction rate preferred stock at an auction if the auction fails, i.e., if more shares of auction rate preferred stock are offered for sale than there are buyers for those shares. Also, if you place an order (a hold order) at an auction to retain auction rate preferred stock only at a specified rate that exceeds the rate set at the auction, you will not retain your auction rate preferred stock. Additionally, if you place a hold order without specifying a rate below which you would not wish to continue to hold your shares and the auction sets a below-market rate, you will receive a lower rate of return on your shares than any market rate of those securities. Finally, the dividend period of these securities may be changed, subject to certain conditions and with notice to the holders of the auction rate preferred stock, which could also affect the liquidity of your investment.

38

##### Table of Contents

If you try to sell your a uction r ate p referred stock between auctions, you may not receive full value on your investment.

If you try to sell your auction rate preferred stock between auctions, you may not be able to sell them for their liquidation preference per share or such amount per share plus accumulated dividends. If we have designated a special dividend period of more than seven days, changes in interest rates could affect the price you would receive if you sold your shares in the secondary market. Broker-dealers that maintain a secondary trading market for the auction rate preferred stock are not required to maintain this market, and and we will not be required to redeem auction rate preferred stock if either an auction or an attempted secondary market sale fails because of a lack of buyers. The auction rate preferred stock will likely not be registered on a stock exchange. If you sell your auction rate preferred stock to a broker-dealer between auctions, you may receive less than the price you paid for them, especially when market interest rates have risen since the last auction or during a special dividend period. Due to recent market disruption most auction-rate preferred stock have been unable to hold successful auctions and holders of such shares have suffered reduced liquidity, including the inability to sell such shares in a secondary market.

The trading market or market value of our publicly issued debt securities or any convertible debt securities, if issued, may be volatile.

Our publicly issued debt securities or any convertible debt securities, if issued, may or may not have an established trading market. We cannot assure investors that a trading market for our publicly issued debt securities or any convertible debt securities would develop or be maintained if developed. In addition to our creditworthiness, many factors may materially adversely affect the trading market for, and market value of, our publicly issued debt securities or any convertible debt securities. These factors include, but are not limited to, the following:

| • |  | the time remaining to the maturity of these debt securities;

| • |  | the outstanding principal amount of debt securities with terms identical to these debt securities;

| • |  | the general economic environment;

| • |  | the supply of debt securities trading in the secondary market, if any;

| • |  | the redemption, repayment or convertible features, if any, of these debt securities;

| • |  | the level, direction and volatility of market interest rates generally; and

| • |  | market rates of interest higher or lower than rates borne by the debt securities.

There also may be a limited number of buyers for our debt securities. This too may materially adversely affect the market value of the debt securities or the trading market for the debt securities. Our debt securities may include convertible features that cause them to more closely bear risks associated with an investment in our common stock.

Our credit ratings, if any, may not reflect all risks of an investment in our debt securities or any convertible debt securities.

Our credit ratings, if any, are an assessment by third parties of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of any publicly issued debt securities. Our credit ratings, however, may not reflect the potential impact of risks related to market conditions generally or other factors discussed herein about the market value of, or trading market for, any publicly issued debt securities.

39

##### Table of Contents

Terms relating to redemption may materially adversely affect the return on any debt securities.

If our debt securities or any convertible debt securities, if issued, are redeemable at our option, we may choose to redeem the debt securities at times when prevailing interest rates are lower than the interest rate paid on the debt securities. In addition, if the debt securities are subject to mandatory redemption, we may be required to redeem the debt securities at times when prevailing interest rates are lower than the interest rate paid on the debt securities. In this circumstance, a holder of our debt securities may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the debt securities being redeemed.

The issuance of subscription rights, warrants or convertible debt that are exchangeable for our common stock, will cause your interest in us to be diluted as a result of any such rights, warrants or convertible debt offering.

Stockholders who do not fully exercise rights, warrants or convertible debt issued to them in any offering of subscription rights, warrants or convertible debt to purchase our common stock should expect that they will, at the completion of the offering, own a smaller proportional interest in us than would otherwise be the case if they fully exercised their rights, warrants or convertible debt. We cannot state precisely the amount of any such dilution in share ownership because we do not know what proportion of the common stock would be purchased as a result of any such offering.

In addition, if the subscription price, warrant price or convertible debt price is less than our net asset value per share of common stock at the time of such offering, then our stockholders would experience an immediate dilution of the aggregate net asset value of their shares as a result of the offering. The amount of any such decrease in net asset value is not predictable because it is not known at this time what the subscription price, warrant price, convertible debt price or net asset value per share will be on the expiration date of such offering or what proportion of our common stock will be purchased as a result of any such offering. The risk of dilution is greater if there are multiple rights offerings. However, our Board of Directors will make a good faith determination that any offering of subscription rights, warrants or convertible debt would result in a net benefit to existing stockholders.

Our stockholders will experience dilution in their ownership percentage if they opt out of our dividend reinvestment plan.

All dividends declared in cash payable to stockholders that are participants in our dividend reinvestment plan are automatically reinvested in shares of our common stock. As a result, our stockholders that opt out of our dividend reinvestment plan will experience dilution in their ownership percentage of our common stock over time.

Future offerings of additional debt securities, which would be senior to our common stock upon liquidation, or equity securities, which could dilute our existing stockholders and may be senior to our common stock for the purposes of distributions, may harm the value of our common stock.

In the future, we may attempt to increase our capital resources by making additional offerings of debt or equity securities, including commercial paper, medium-term notes, senior or subordinated notes and classes of preferred stock or common stock, subject to the restrictions of the 1940 Act. Upon a liquidation of our company, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings would receive a distribution of our available assets prior to the holders of our common stock. Additional equity offerings by us may dilute the holdings of our existing stockholders or reduce the value of our common stock, or both. Any preferred stock we may issue would have a preference on distributions that could limit our ability to make distributions to the holders of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future offerings

40

##### Table of Contents

reducing the market price of our common stock and diluting their stock holdings in us. In addition, proceeds from a sale of common stock will likely be used to increase our total assets or to pay down our borrowings, among other uses. This would increase our asset coverage ratio and permit us to incur additional leverage under rules pertaining to BDCs by increasing our borrowings or issuing senior securities such as preferred stock or additional debt securities.

Terrorist attacks, acts of war or national 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 national 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.

FORMATION TRANSACTIONS

Triangle Capital Corporation is a Maryland corporation, formed on October 10, 2006, for the purposes of acquiring 100% of the equity interests in Triangle SBIC and its general partner, TML, raising capital in our IPO, which was completed in February 2007 and thereafter operating as an internally managed business development company under the 1940 Act.

On February 21, 2007, concurrently with the closing of our IPO, we consummated the following formation transactions:

| • |  | Triangle Capital Corporation acquired 100% of the limited partnership interests in Triangle SBIC in exchange for approximately 1.4 million shares of Triangle’s common stock, having an aggregate value of $21,250,000 based on the IPO price. Triangle SBIC became our wholly owned subsidiary, retained its SBIC license, continues to hold its existing investments and will make new investments with the proceeds from our IPO.

| • |  | Triangle Capital Corporation acquired 100% of the equity interests in TML, the general partner of Triangle SBIC, in exchange for 500,000 shares of Triangle’s common stock, having an aggregate value of $7,500,000 based on the IPO price.

On December 15, 2009, Triangle SBIC II was organized as a limited partnership under the laws of the State of Delaware and its SBIC license became effective on May 26, 2010. We have made and we will continue to make new investments with the net proceeds of any offering and proceeds from SBA guaranteed debentures issued from time to time to our two wholly owned SBIC subsidiaries. The financial statements of the Company include the accounts of Triangle Capital Corporation and its wholly-owned subsidiaries, including Triangle SBIC and Triangle SBIC II.

BUSINESS DEVELOPMENT COMPANY AND REGULATED INVESTMENT COMPANY ELECTIONS

We and Triangle SBIC are closed-end, non-diversified management investment companies that have elected to be treated as BDCs under the 1940 Act. In addition, we have elected to be treated as a RIC under Subchapter M of the Code. Our election to be regulated as a BDC and our election to be treated as a RIC for federal income tax purposes have a significant impact on our operations. Some of the most important effects on our operations of our election to be regulated as a BDC and our election to be treated as a RIC are outlined below.

We report our investments at market value or fair value with changes in value reported through our statements of operations.

In accordance with the requirements of Article 6 of Regulation S-X, we report all of our investments, including debt investments, at market value or, for investments that do not have a readily available market value, at their “fair value” as determined in good faith by our Board of Directors. Changes in these values will be reported through our statements of operations under the caption of “net unrealized appreciation (depreciation) of investments.” See “Business — Valuation Process and Determination of Net Asset Value.”

##### Table of Contents

We intend to distribute substantially all of our income to our stockholders. We generally will be required to pay income taxes only on the portion of our taxable income we do not distribute to stockholders (actually or constructively).

As a RIC, so long as we meet certain minimum distribution, source-of-income and asset diversification requirements, we generally are required to pay U.S. federal income taxes only on the portion of our taxable income and gains we do not distribute (actually or constructively) and certain built-in gains. We intend to distribute to our stockholders substantially all of our income. We may, however, make deemed distributions to our stockholders of any retained net long-term capital gains. If this happens, our stockholders will be treated as if they received an actual distribution of the net capital gains and reinvested the net after-tax proceeds in us. Our stockholders also may be eligible to claim a tax credit (or, in certain circumstances, a tax refund) equal to their allocable share of the corporate-level U.S. federal income tax we pay on the deemed distribution. See “Material U.S. Federal Income Tax Considerations.” We met the minimum annual distribution requirements for 2008, 2009, 2010 and 2011 and continually monitor our distribution requirements with the goal of ensuring compliance with the Code.

In addition, we have certain wholly-owned taxable subsidiaries, or the Taxable Subsidiaries, each of which holds a portion of one or more of our portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiaries are consolidated for financial reporting purposes in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, so that our consolidated financial statements reflect our investments in the portfolio companies owned by the Taxable Subsidiaries. The purpose of the Taxable Subsidiaries is to permit us to hold certain interests in portfolio companies that are organized as limited liability companies, or LLCs, (or other forms of pass-through entities) and still satisfy the RIC tax requirement that at least 90.0% of the RIC’s gross income for federal income tax purposes must consist of investment income. Absent the Taxable Subsidiaries, a proportionate amount of any gross income of an LLC (or other pass-through entity) portfolio investment would flow through directly to the RIC. To the extent that such income did not consist of investment income, it could jeopardize our ability to qualify as a RIC and therefore cause us to incur significant amounts of corporate-level U.S. federal income taxes. Where interests in LLCs (or other pass-through entities) are owned by the Taxable Subsidiaries, however, the income from such interests is taxed to the Taxable Subsidiaries and does not flow through to the RIC, thereby helping us preserve our RIC status and resultant tax advantages. The Taxable Subsidiaries are not consolidated for U.S. federal income tax purposes and may generate income tax expense as a result of their ownership of the portfolio companies.

Our ability to use leverage as a means of financing our portfolio of investments is limited.

As a BDC, we are required to meet a coverage ratio of total assets to total senior securities of at least 200.0%. For this purpose, senior securities include all borrowings (other than SBA leverage and certain other short-term borrowings) and any preferred stock we may issue in the future. Additionally, our ability to continue to utilize leverage as a means of financing our portfolio of investments may be limited by this asset coverage test. Our SBIC subsidiaries cannot have outstanding more than an aggregate of $225.0 million of debenture leverage guaranteed by the SBA. This limitation may negatively impact our earnings, as we are at or close to that limit. While use of debenture leverage from the SBA may enhance returns if we meet our investment objective, our returns may be reduced or eliminated if the returns on investments by Triangle SBIC and Triangle SBIC II are less than the costs of operating them, including the costs of using debenture leverage.

We are required to comply with the provisions of the 1940 Act applicable to business development companies.

As a BDC, we are required to have a majority of directors who are not “interested” persons under the 1940 Act. In addition, we are required to comply with other applicable provisions of the 1940 Act, including those requiring the adoption of a code of ethics, fidelity bonding and investment custody arrangements. See “Regulation” below.

USE OF PROCEEDS

Unless otherwise specified in any prospectus supplement accompanying this prospectus, we intend to use the net proceeds from the sale of our securities for investment and general corporate purposes, including repaying any amounts outstanding under the Credit Facility. We intend to invest the net proceeds in lower middle market companies in accordance with our investment objective and strategies and for working capital and general corporate purposes. We plan to raise new equity when we have attractive investment opportunities available. Pending such use, we will invest the net proceeds of any offering primarily in short-term securities consistent with our BDC election and our election to be taxed as a RIC. See “Regulation — Temporary Investments.”

Our ability to achieve our investment objective may be limited to the extent that the net proceeds from an offering, pending full investment, are held in interest-bearing deposits or other short-term instruments. The supplement to this prospectus relating to an offering will more fully identify the use of proceeds from such an offering.

RATIO OF EARNINGS TO FIXED CHARGES

For the years ended December 31, 2007, 2008, 2009, 2010 and 2011 and the three months ended March 31, 2012, the ratios of earnings to fixed charges of the Company, computed as set forth below, were as follows:

|  | For the Year Ended December 31, 2007 |  |  | For the Year Ended December 31, 2008 |  |  | For the Year Ended December 31, 2009 |  |  | For the Year Ended December 31, 2010 |  |  | For the Year Ended December 31, 2011 |  |  | For the Three Months Ended March 31, 2012 |
Earnings to Fixed Charges(1) |  |  | 5.06 |  |  |  | 2.73 |  |  |  | 1.58 |  |  |  | 4.14 |  |  |  | 6.22 |  |  |  | 4.59 |

For purposes of computing the ratios of earnings to fixed charges, earnings represent net increase in net assets resulting from operations plus (or minus) income tax provision (benefit) including excise tax expense plus fixed charges. Fixed charges include interest and credit facility fees, amortization of deferred financing fees and losses on extinguishment of debt.

(1) | Earnings include net realized and unrealized gains or losses. Net realized and unrealized gains or losses can vary substantially from period to period.

| • |  | Excluding net unrealized gains or losses, the earnings to fixed charges ratio would be 3.66 for the year ended December 31, 2007, 3.69 for the year ended December 31, 2008, 3.00 for the year ended December 31, 2009, 2.80 for the year ended December 31, 2010, 5.64 for the year ended December 31, 2011 and 4.41 for the three months ended March 31, 2012.

| • |  | Excluding net realized and unrealized gains or losses, the earnings to fixed charges ratio would be 3.94 for the year ended December 31, 2007, 3.37 for the year ended December 31, 2008, 2.93 for the year ended December 31, 2009, 3.47 for the year ended December 31, 2010, 4.65 for the year ended December 31, 2011 and 4.41 for the three months ended March 31, 2012.

(1) | Net asset value per share is determined as of the last day in the relevant quarter and therefore may not reflect the net asset value per share on the date of the high and low sales prices. The net asset values shown are based on outstanding shares at the end of each period.

(2) | Calculated as the respective high or low sales price divided by net asset value.

(3) | Represents the distribution declared in the specified quarter. We have adopted an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a distribution, then stockholders’ cash distributions will be automatically reinvested in additional shares of our common stock, unless they specifically “opt out” of the dividend reinvestment plan so as to receive cash distributions. See “Dividend Reinvestment Plan.”

* | Not determinable at the time of filing.

The last reported price for our common stock on June 5, 2012 was $20.46 per share.

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

We intend to continue to pay quarterly distributions to our stockholders. Our quarterly distributions, if any, are determined by our Board of Directors. We have elected to be taxed as a RIC under Subchapter M of the Code. As long as we qualify as a RIC, we will not be taxed on our investment company taxable income or realized net capital gain, to the extent that such taxable income or gain is distributed, or deemed to be distributed, to stockholders on a timely basis.

##### Table of Contents

To obtain and maintain RIC tax treatment, we must, among other things, distribute at least 90.0% of our net ordinary income and realized net short-term capital gain in excess of realized net long-term capital loss, if any. In order to avoid certain excise taxes imposed on RICs, we currently intend to distribute during each calendar year an amount at least equal to the sum of (1) 98.0% of our net ordinary income for the calendar year, (2) 98.2% of our net capital gain for the calendar year and (3) any net ordinary income and net capital gain for preceding years that were not distributed during such years and on which we paid no U.S. federal income tax. We may retain for investment some or all of our net capital gain (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, you will be treated as if you received an actual distribution of the capital gain we retain and then reinvested the net after-tax proceeds in our common stock. You also may be eligible to claim a tax credit (or, in certain circumstances, a tax refund) equal to your allocable share of the tax we paid on the capital gain deemed distributed to you. Please refer to “Material U.S. Federal Income Tax Considerations” for further information regarding the consequences of our retention of net capital gain. We may, in the future, make actual distributions to our stockholders of our net capital gain. 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 will 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. See “Regulation” and “Material U.S. Federal Income Tax Considerations.”

We may make distributions that are payable in cash or shares of our common stock at the election of each stockholder. Under certain applicable provisions of the Code and the Treasury regulations, distributions payable in cash or in shares of stock at the election of stockholders are treated as taxable dividends to the extent of current and accumulated earnings and profits. The Internal Revenue Service has issued private rulings 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. Under these rulings, 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. If we decide to make any distributions consistent with these rulings that are payable in part in our stock, taxable stockholders receiving such dividends will be required to include the full amount of the distribution (whether received in cash, our stock, or a combination thereof) as ordinary income (or as 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 distributions 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 distribution, 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 distributions, including in respect of all or a portion of such distribution 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 distributions, it may put downward pressure on the trading price of our stock.

We will report the U.S. federal income tax characteristics of all distributions to our stockholders, as appropriate, on IRS Form 1099-DIV after the end of the year. Our ability to pay distributions could be affected by future business performance, liquidity, capital needs, alternative investment opportunities and loan covenants.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information in this section contains forward-looking statements that involve risks and uncertainties. Please see “Risk Factors” and “Special Note Regarding Forward-Looking Statements” for a discussion of the uncertainties, risks and assumptions associated with these statements. You should read the following discussion in conjunction with the financial statements and related notes and other financial information appearing elsewhere in this prospectus.

The following discussion is designed to provide a better understanding of our consolidated financial statements, including a brief discussion of our business, key factors that impacted our performance and a summary of our operating results. The following discussion should be read in conjunction with the financial statements and the notes thereto included herein. Historical results and percentage relationships among any amounts in the financial statements are not necessarily indicative of trends in operating results for any future periods.

Overview of our Business

We are a Maryland corporation which has elected to be treated and operates as an internally managed business development company, or BDC, under the Investment Company Act of 1940, or 1940 Act. Our wholly-owned subsidiaries, Triangle Mezzanine Fund LLLP, or Triangle SBIC, and Triangle Mezzanine Fund II LP, or Triangle SBIC II, are licensed as small business investment companies, or SBICs, by the United States Small Business Administration, or SBA. In addition, Triangle SBIC has also elected to be treated as a BDC under the 1940 Act. We, Triangle SBIC and Triangle SBIC II invest primarily in debt instruments, equity investments, warrants and other securities of lower middle market privately held companies located in the United States.

Our business is to provide capital to lower middle market companies in the United States. We focus on investments in companies with a history of generating revenues and positive cash flows, an established market position and a proven management team with a strong operating discipline. Our target portfolio company has annual revenues between $20.0 million and $200.0 million and annual earnings before interest, taxes, depreciation and amortization, or EBITDA, between $3.0 million and $20.0 million.

We invest primarily in subordinated debt securities secured by second lien security interests in portfolio company assets, coupled with equity interests. On a more limited basis, we also invest in senior debt securities secured by first lien security interests in portfolio companies. Our investments generally range from $5.0 million to $25.0 million per portfolio company. In certain situations, we have partnered with other funds to provide larger financing commitments.

We generate revenues in the form of interest income, primarily from our investments in debt securities, loan origination and other fees and dividend income. Loan origination fees received in connection with our debt investments are recognized as investment income over the life of the loan using the effective interest method or, in some cases, recognized as earned. We also receive fees from our portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received. In addition, we generate revenue in the form of capital gains, if any, on warrants or other equity-related securities that we acquire from our portfolio companies. Our debt investments generally have a term of between three and seven years and typically bear interest at fixed rates between 12.0% and 17.0% per annum. Certain of our debt investments have a form of interest, referred to as payment in kind, or PIK, interest, that is not paid currently but is instead accrued and added to the loan balance and paid at the end of the term. In our negotiations with potential portfolio companies, we generally seek to minimize PIK interest. Cash interest on our debt investments is generally payable monthly; however, some of our debt investments pay cash interest on a quarterly basis. As of March 31, 2012 and December 31, 2011 the weighted average yield on our outstanding debt investments other than non-accrual debt investments (including PIK interest) was approximately 15.1% and 15.0%, respectively. The

weighted average yield on all of our outstanding investments (including equity and equity-linked investments but excluding non-accrual debt investments) was approximately 14.0% and 13.9% as of March 31, 2012 and December 31, 2011, respectively. The weighted average yield on all of our outstanding investments (including equity and equity-linked investments and non-accrual debt investments) was approximately 13.8% and 13.6% as of March 31, 2012 and December 31, 2011, respectively.

Triangle SBIC and Triangle SBIC II are eligible to issue debentures to the SBA, which pools these with debentures of other SBICs and sells them in the capital markets at favorable interest rates, in part as a result of the guarantee of payment from the SBA. Triangle SBIC and Triangle SBIC II invest these funds in portfolio companies. We intend to continue to operate Triangle SBIC and Triangle SBIC II as SBICs, subject to SBA approval, and to utilize the proceeds from the issuance of SBA-guaranteed debentures, referred to herein as SBA leverage, to enhance returns to our stockholders.

Non-Accrual Assets

Generally, when interest and/or principal payments on a loan become past due, or if we otherwise do not expect the borrower to be able to service its debt and other obligations, we will place the loan on non-accrual status and will generally cease recognizing interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. As of December 31, 2011, the fair value of our non-accrual assets was approximately $7.6 million, which comprised 1.5% of the total fair value of our portfolio, and the cost of our non-accrual assets was approximately $11.0 million, which comprised 2.2% of the total cost of our portfolio. As of March 31, 2012, the fair value of our non-accrual assets was approximately $2.2 million, which comprised 0.4% of the total fair value of our portfolio, and the cost of our non-accrual assets was approximately $6.0 million, which comprised 1.1% of the total cost of our portfolio.

Our non-accrual assets as of March 31, 2012 are as follows:

Gerli and Company

In November 2008, we placed our debt investment in Gerli and Company, or Gerli, on non-accrual status. As a result, under generally accepted accounting principles in the United States, or U.S. GAAP, we no longer recognize interest income on our debt investment in Gerli for financial reporting purposes. During the first quarter of 2011, we restructured our investment in Gerli. As a result of the restructuring, we received a new note from Gerli with a face amount of $3.0 million and a fair value of approximately $2.3 million and preferred stock with a liquidation preference of $0.4 million. Under the terms of the new note, interest on the note is payable only if Gerli meets certain covenants, which they were not compliant with as of March 31, 2012. In the three months ended March 31, 2012, we recognized unrealized appreciation on our debt investment in Gerli of approximately $0.1 million. As of March 31, 2012, the cost of our debt investment in Gerli was $3.0 million and the fair value was $2.0 million.

Fire Sprinkler Systems, Inc.

In October 2008, we placed our debt investment in Fire Sprinkler Systems, Inc., or Fire Sprinkler Systems, on non-accrual status. As a result, under U.S. GAAP, we no longer recognize interest income on our debt investment in Fire Sprinkler Systems for financial reporting purposes. In the three months ended, March 31, 2011, we recorded unrealized depreciation of $0.4 million on our debt investment in Fire Sprinkler Systems. As of March 31, 2012, the cost of our debt investment in Fire Sprinkler Systems was $3.0 million and the fair value of such investment was $0.2 million.

PIK Non-Accrual Asset

In addition, in certain circumstances, we may receive current cash interest payments related to a loan, but because we do not expect the borrower to be able to meet its debt obligations with respect to PIK interest, we will not recognize contractual PIK interest on the loan for financial reporting purposes. As of December 31, 2011, there were no investments on PIK non-accrual status. As of March 31, 2012, both the fair value and cost of our “PIK non-accrual asset” were approximately $5.2 million, which comprised 1.0% of both the total fair value of our portfolio and the cost of our portfolio.

Our PIK non-accrual asset as of March 31, 2012 is as follows:

American De-Rosa Lamparts, LLC and Hallmark Lighting

In September 2009, we received notification from ADL’s senior lender that ADL was blocked from making interest payments to us. As a result, we placed our investment in ADL on non-accrual status and, under U.S. GAAP, we no longer recognized interest income on our investment in ADL for financial reporting purposes. In

June 2010, we converted approximately $3.0 million of our subordinated debt in ADL to equity as part of a restructuring, resulting in realized loss of approximately $3.0 million. In addition, as part of the 2010 restructuring agreement, in January 2012, ADL began making cash interest payments at a rate of 12% on our subordinated note.

Results of Operations

Comparison of three months ended March 31, 2012 and March 31, 2011

Investment Income

For the three months ended March 31, 2012, total investment income was $19.1 million, a 54% increase from $12.4 million of total investment income for the three months ended March 31, 2011. This increase was primarily attributable to a $6.7 million increase in total loan interest, fee and dividend income (including PIK interest income) due to a net increase in our portfolio investments from March 31, 2011, to March 31, 2012, partially offset by a decrease in non-recurring fee income of approximately $0.1 million. Non-recurring fee income was approximately $0.4 million for the three months ended March 31, 2012 as compared to $0.5 million for the three months ended March 31, 2011.

Expenses

For the three months ended March 31, 2012, expenses increased by 52% to $6.9 million from $4.5 million for the three months ended March 31, 2011. The increase in expenses was attributable to a $1.1 million increase in interest and credit facility fees, a $0.1 million increase in amortization of deferred financing fees and a $1.2 million increase in general and administrative expenses. The increase in interest and credit facility fees is related to (i) interest on our 7.00% Senior Notes due 2019, or Senior Notes, of approximately $0.4 million in the quarter ended March 31, 2012, (ii) credit facility fees of approximately $0.1 million in the quarter ended March 31, 2012, and (iii) higher weighted-average rates on outstanding SBA-guaranteed debentures in the quarter ended March 31, 2012 as compared to weighted-average rates on outstanding SBA-guaranteed debentures in the quarter ended March 31, 2011. The increase in general and administrative expenses in the quarter ended March 31, 2012 was primarily related to increased salary and incentive compensation costs, as well as increased non-cash compensation expenses.

Net Investment Income

As a result of the $6.7 million increase in total investment income and the $2.4 million increase in expenses, net investment income increased by 55% to $12.2 million for the three months ended March 31, 2012 as compared to net investment income of $7.9 million for the three months ended March 31, 2011.

Net Increase/Decrease in Net Assets Resulting from Operations

During the three months ended March 31, 2012, we recorded net unrealized appreciation of investments totaling approximately $0.6 million, comprised of unrealized appreciation on 33 investments totaling approximately $5.7 million and unrealized depreciation on 12 investments totaling approximately $5.1 million. During the three months ended March 31, 2011, we recorded net unrealized appreciation of investments totaling approximately $4.6 million, comprised of unrealized appreciation on 17 investments totaling approximately $7.0 million and unrealized depreciation on 17 investments totaling approximately $2.4 million.

During both the three months ended March 31, 2012 and 2011, we recognized losses on extinguishment of debt of approximately $0.2 million related to prepayments of SBA-guaranteed debentures.

As a result of these events, our net increase in net assets from operations was $12.6 million for the three months ended March 31, 2012 as compared to a net increase in net assets from operations of $12.4 million for the three months ended March 31, 2011.

Comparison of year ended December 31, 2011 and December 31, 2010

Investment Income

For the year ended December 31, 2011, total investment income was $63.4 million, a 76% increase from $36.0 million of total investment income for the year ended December 31, 2010. This increase was primarily attributable to a $27.4 million increase in total loan interest, fee and dividend income (including PIK interest income). The increase in total loan interest, fee and dividend income was due to 1) a net increase in our portfolio investments from December 31, 2010 to December 31, 2011, and 2) an increase in non-recurring fee income of approximately $0.7 million. Non-recurring fee income was approximately $3.3 million for the year ended December 31, 2011, as compared to approximately $2.6 million for the year ended December 31, 2010. In addition, interest income from cash and cash equivalents increased by 5% from $0.3 million in 2010 to $0.4 million in 2011 due to an increase in average cash balances.

Expenses

For the year ended December 31, 2011, expenses increased by 45% to $23.0 million from $15.8 million for the year ended December 31, 2010. The increase in expenses was attributable to a $2.8 million increase in interest expense, a $0.1 million increase in amortization of deferred financing fees and a $4.3 million increase in general and administrative expenses. The increase in interest expense is related to higher average balances of SBA-guaranteed debentures outstanding during the year ended December 31, 2011 than in the comparable period in 2010 and the addition of our Credit Facility during 2011. The increase in amortization of deferred financing fees is primarily associated with the early repayment of certain SBA-guaranteed debentures in the first quarter of 2011. The increase in general and administrative costs in 2011 was primarily related to increased salary and incentive compensation costs and increased non-cash compensation expenses driven in part by an increase in employee headcount.

Net Investment Income

As a result of the $27.4 million increase in total investment income and the $7.2 million increase in expenses, net investment income for the year ended December 31, 2011 was $40.3 million compared to net investment income of $20.1 million during the year ended December 31, 2010.

Net Increase in Net Assets Resulting From Operations

For the year ended December 31, 2011, we realized a gain on the sale of one control investment of approximately $12.2 million, a loss on the disposal of one control investment of $0.1 million and a loss on the conversion of debt to equity of $3.0 million related to one control investment. In addition, we realized a gain on the repayment of a non-control/non-affiliate investment of approximately $0.5 million, and a gain on the sale of two non-control/non-affiliate investments of $1.4 million. In addition, during the year ended December 31, 2011, we recorded net unrealized appreciation of investments totaling approximately $6.4 million, comprised of 1) unrealized appreciation on 33 investments totaling approximately $25.6 million, 2) unrealized depreciation on 19 investments totaling approximately $9.6 million and 3) $9.6 million of net unrealized depreciation reclassification adjustments related to the realized gains and losses noted above.

For the year ended December 31, 2010, we realized a gain on the sale of one affiliate investment of approximately $3.6 million, gains on the sales of two non-control/non-affiliate investments totaling approximately $0.5 million, a realized loss on the partial conversion of one non-control/non-affiliate debt investment to equity of approximately $3.0 million, a realized loss on the conversion of one affiliate debt investment to equity of approximately $7.4 million, and a realized gain of $0.9 million on the repayment of a convertible note from another non-control/non-affiliate investment. In addition, during the year ended December 31, 2010; we recorded net unrealized appreciation of investments totaling approximately $10.9 million, comprised of 1) unrealized appreciation on 19 investments totaling approximately $18.6 million,

2) unrealized depreciation on 18 investments totaling approximately $13.9 million and 3) $6.2 million in net unrealized appreciation reclassification adjustments related to the realized gains and realized loss noted above.

As a result of these events, our net increase in net assets from operations during the year ended December 31, 2011 was $56.8 million as compared to $25.4 million for the year ended December 31, 2010.

Comparison of year ended December 31, 2010 and December 31, 2009

Investment Income

For the year ended December 31, 2010, total investment income was $36.0 million, a 30% increase from $27.8 million of total investment income for the year ended December 31, 2009. This increase was primarily attributable to a $7.6 million increase in total loan interest, fee and dividend income and a $0.9 million increase in total PIK interest income due to a net increase in our portfolio investments from December 31, 2009 to December 31, 2010, partially offset by a $0.3 million decrease in interest income from cash and cash equivalent investments due to a decrease in average cash balances in 2010 over 2009 due to the increased deployment of cash for purchases of portfolio investments. Non-recurring fee income was $2.6 million for the year ended December 31, 2010 as compared to $0.8 million for the year ended December 31, 2009.

Expenses

For the year ended December 31, 2010, expenses increased by 15% to $15.8 million from $13.7 million for the year ended December 31, 2009. The increase in expenses was primarily attributable to a $1.2 million increase in general and administrative expenses as a result of higher salary expenses during 2010 due to an increase in employees and non-cash compensation expenses. The increase in expenses was also attributable to a $0.4 million increase in amortization of deferred financing fees associated with the early repayment of certain SBA-guaranteed debentures in the third quarter of 2010 and a $0.4 million increase in interest expense as a result of higher average balances of SBA-guaranteed debentures outstanding during the year ended December 31, 2010 than in the same period in 2009.

Net Investment Income

As a result of the $8.2 million increase in total investment income and the $2.1 million increase in expenses, net investment income for the year ended December 31, 2010 was $20.1 million compared to net investment income of $14.0 million during the year ended December 31, 2009.

Liquidity and Capital Resources

We believe that our current cash and cash equivalents on hand, available leverage under our line of credit and our anticipated cash flows from operations will be adequate to meet our cash needs for our daily operations for at least the next twelve months.

In the future, depending on the valuation of Triangle SBIC’s assets and Triangle SBIC II’s assets pursuant to SBA guidelines, Triangle SBIC and Triangle SBIC II may be limited by provisions of the Small Business Investment Act of 1958, and SBA regulations governing SBICs, from making certain distributions to Triangle Capital Corporation that may be necessary to enable Triangle Capital Corporation to make the minimum required distributions to its stockholders and qualify as a Regulated Investment Company, or RIC.

Financing Transactions

Due to Triangle SBIC’s and Triangle SBIC II’s status as licensed SBICs, Triangle SBIC and Triangle SBIC II have the ability to issue debentures guaranteed by the SBA at favorable interest rates. Under the Small Business Investment Act and the SBA rules applicable to SBICs, an SBIC (or group of SBICs under common control) can have outstanding at any time debentures guaranteed by the SBA up to two times (and in certain cases, up to three times) the amount of its regulatory capital, which generally is the amount raised from private investors. As of March 31, 2012, the maximum statutory limit on the dollar amount of outstanding debentures guaranteed by the SBA issued by a single SBIC is $150.0 million and by a group of SBICs under common control is $225.0 million. Debentures guaranteed by the SBA have a maturity of ten years, with interest payable semi-annually. The principal amount of the debentures is not required to be paid before maturity but may be pre-paid at any time, without penalty.

As of March 31, 2012, Triangle SBIC has issued $139.6 million of SBA-guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of March 31, 2012, Triangle SBIC II has issued $75.0 million in face amount of SBA-guaranteed debentures. In addition to the one-time 1.0% fee on the total commitment from the SBA, the Company also pays a one-time 2.425% fee on the amount of each debenture issued (2.0% for SBA LMI debentures). These fees are capitalized as deferred financing costs and are amortized over the term of the debt agreements using the effective interest method. The weighted average interest rate for all SBA-guaranteed debentures as of March 31, 2012 was 4.76%.

In May 2011, we entered into a three-year senior secured credit facility (the “Credit Facility”) with an initial commitment of $50.0 million. In November 2011, we closed an expansion of the Credit Facility from $50.0 million to $75.0 million, which included the addition of one new lender. The purpose of the Credit Facility is to provide additional liquidity in support of future investment and operational activities. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and has an accordion feature which allows for an increase in the total loan size up to $90.0 million and also contains two one-year extension options, bringing the total potential commitment and funding period to five years from the closing date. The Credit Facility, which is structured to operate like a revolving credit facility, is secured primarily by Triangle Capital Corporation’s assets, excluding the assets of Triangle SBIC and Triangle SBIC II.

Borrowings under the Credit Facility bear interest, subject to our election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or (ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of (i) prime rate, (ii) the federal funds rate plus 0.5% or (iii) the adjusted one-month LIBOR plus 2.0%. We pay unused commitment fees of 0.375% per annum, which are included in “Interest and credit facility fees” on our Consolidated Statement of Operations. As of March 31, 2012, the Company had no borrowings outstanding under the Credit Facility.

The Senior Notes mature on March 15, 2019, and may be redeemed in whole or in part at any time or from time to time at our option on or after March 15, 2015. The Senior Notes bear interest at a rate of 7.00% per year payable quarterly on March 15, June 15, September 15 and December 15 of each year, beginning June 15, 2012. The net proceeds from the sale of the Senior Notes, after underwriting discounts and offering expenses, were approximately $66.8 million.

Distributions to Stockholders

We have elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended, or the “Code,” and intend to make the required distributions to our stockholders as specified therein. In order to qualify as a RIC and to obtain RIC tax benefits, we must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then we are generally required to pay income taxes only on the portion of our taxable income and gains we do not distribute (actually or constructively) and certain built-in gains. We met our minimum distribution requirements for 2011, 2010, 2009, 2008 and 2007 and continually monitor our distribution requirements with the goal of ensuring compliance with the Code.

The minimum distribution requirements applicable to RICs require us to distribute to our stockholders each year at least 90% of our investment company taxable income, or “ICTI,” as defined by the Code. Depending on the level of ICTI earned in a tax year, we may choose to carry forward ICTI in excess of current year distributions into the next tax year and pay a 4% excise tax on such excess. Any such carryover ICTI must be distributed before the end of the next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI.

ICTI generally differs from net investment income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. We may be required to recognize ICTI in certain 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), we must include in ICTI 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 ICTI other amounts that we have not yet received in cash, such as (i) PIK interest income and (ii) interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. Because any original issue discount or other amounts accrued will be included in our ICTI for the year of accrual, we may be required to make a distribution to our stockholders in order to satisfy the minimum distribution requirements, even though we will not have received and may not ever receive any corresponding cash amount. ICTI also excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

Current Market Conditions

Beginning in 2008, the debt and equity capital markets in the United States were severely impacted by significant write-offs in the financial services sector relating to subprime mortgages and the re-pricing of credit risk in the broadly syndicated bank loan market, among other factors. These events, along with the deterioration of the housing market, led to an economic recession in the U.S. and abroad. Banks, investment companies and others in the financial services industry reported significant write-downs in the fair value of their assets, which led to the failure of a number of banks and investment companies, a number of distressed mergers and acquisitions, the government take-over of the nation’s two largest government-sponsored mortgage companies, the passage of the $700 billion Emergency Economic Stabilization Act of 2008 in October 2008 and the passage of the American Recovery and Reinvestment Act of 2009, or the Stimulus Bill, in February 2009. These events significantly impacted the financial and credit markets and reduced the availability of debt and equity capital for the market as a whole, and for financial firms in particular. Notwithstanding recent gains across both the equity and debt markets, these conditions may reoccur in the future and could then continue for a prolonged period of time. Although we have been able to secure access to additional liquidity, including our recent public offerings of

common stock and debt securities, increased leverage available through the SBIC program as a result of the Stimulus Bill and our $75.0 million Credit Facility, there is no assurance that debt or equity capital will be available to us in the future on favorable terms, or at all.

Recent Developments

In April 2012, we invested $23.0 million in subordinated debt and equity of WSO Holdings, LP (“WSO”), a producer of organic and fair trade sugars, syrups, nectars and honeys. Under the terms of the investment, WSO will pay interest on the subordinated debt at a rate of 14% per annum.

In April 2012, we received a full repayment of our subordinated debt investments in Novolyte Technologies, Inc. (“Novolyte”). In addition, we sold our preferred and common equity interests in Novolyte for net proceeds of approximately $3.2 million, resulting in a realized gain of approximately $2.4 million.

In April 2012, we invested $7.0 million in subordinated debt of Tomich Brothers, LLC (“Tomich”), a processor and world-wide distributor of seafood indigenous to the waters of California. Under the terms of the investment, Tomich will pay interest on the subordinated debt at a rate of 15% per annum.

In April 2012, we invested $18.5 million in senior subordinated debt and equity of Chromaflo Technologies, LLC. (“Chromaflo”), a developer, manufacturer and distributor of architectural and industrial colorants for the paint and coatings industries. Under the terms of the investment, Chromaflo will pay interest on the senior subordinated debt at a rate of 14% per annum.

Critical Accounting Policies and Use of Estimates

The preparation of our unaudited financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the periods covered by such financial statements. We have identified investment valuation and revenue recognition as our most critical accounting estimates. On an on-going basis, we evaluate our estimates, including those related to the matters described below. These estimates are based on the information that is currently available to us and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates under different assumptions or conditions. A discussion of our critical accounting policies follows.

Investment Valuation Process

We have established and documented processes and methodologies for determining the fair values of portfolio company investments on a recurring basis in accordance with the 1940 Act and FASB ASC Topic 820, Fair Value Measurements and Disclosures, or ASC Topic 820. Under ASC Topic 820, a financial instrument is categorized within the ASC Topic 820 valuation hierarchy based upon the lowest level of input to the valuation process that is significant to the fair value measurement. The three levels of valuation inputs established by ASC Topic 820 are as follows:

Level 1 Inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 Inputs — include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 Inputs — include inputs that are unobservable and significant to the fair value measurement.

Our investment portfolio is comprised of debt and equity instruments of privately held companies for which quoted prices or other inputs falling within the categories of Level 1 and Level 2 are not available. Therefore, we determine the fair value of our investments in good faith using level 3 inputs, pursuant to a valuation policy and

63

##### Table of Contents

process that is established by our management with the assistance of certain third-party advisors and subsequently approved by our Board of Directors. There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. The recorded fair values of our investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned.

Our valuation process is led by our executive officers and managing directors. The valuation process begins with a quarterly review of each investment in our investment portfolio by our executive officers and our investment committee. Valuations of each portfolio security are then prepared by our investment professionals, who have direct responsibility for the origination, management and monitoring of each investment. Under our valuation policy, each investment valuation is subject to (i) a review by the lead investment officer responsible for the portfolio company investment and (ii) a peer review by a second investment officer or executive officer. Generally, any investment that is valued below cost is subjected to review by one of our executive officers. After the peer review is complete, we engage Duff & Phelps, LLC (“Duff & Phelps”), an independent valuation firm, to provide a third-party review of certain investments, as described further below. In addition, all investment valuations are provided to our independent registered public accounting firm each quarter in connection with quarterly review procedures and the annual audit of our financial statements. Finally, the Board of Directors has the responsibility for reviewing and approving, in good faith, the fair value of our investments in accordance with the 1940 Act.

Duff & Phelps provides third party valuation consulting services to us which consist of certain limited procedures that we identified and requested Duff & Phelps to perform (hereinafter referred to as the “procedures”). We generally request Duff & Phelps to perform the procedures on each portfolio company at least once in every calendar year and for new portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In addition, we generally request Duff & Phelps to perform the procedures on a portfolio company when there has been a significant change in the fair value of the investment. In certain instances, we may determine that it is not cost-effective, and as a result is not in our stockholders’ best interest, to request Duff & Phelps to perform the procedures on one or more portfolio companies. Such instances include, but are not limited to, situations where the fair value of the investment in the portfolio company is determined to be insignificant relative to the total investment portfolio.

The total number of investments and the percentage of our portfolio on which we asked Duff & Phelps to perform such procedures since January 1, 2009 are summarized below by period:

For the Quarter Ended: |  | Total Companies |  |  | Percent of Total Investments at Fair Value(1) |
March 31, 2009 |  |  | 7 |  |  |  | 26 | %
June 30, 2009 |  |  | 6 |  |  |  | 20 | %
September 30, 2009 |  |  | 7 |  |  |  | 24 | %
December 31, 2009 |  |  | 8 |  |  |  | 40 | %
March 31, 2010 |  |  | 7 |  |  |  | 25 | %
June 30, 2010 |  |  | 8 |  |  |  | 29 | %
September 30, 2010 |  |  | 8 |  |  |  | 26 | %
December 31, 2010 |  |  | 9 |  |  |  | 29 | %
March 31, 2011 |  |  | 11 |  |  |  | 34 | %
June 30, 2011 |  |  | 13 |  |  |  | 26 | %
September 30, 2011 |  |  | 11 |  |  |  | 31 | %
December 31, 2011 |  |  | 12 |  |  |  | 22 | %
March 31, 2012 |  |  | 10 |  |  |  | 19 | %

| (1) | Exclusive of the fair value of new investments made during the quarter

Upon completion of the procedures, Duff & Phelps concluded that the fair value of those investments subjected to the procedures appeared reasonable. Our Board of Directors is ultimately responsible for determining the fair value of our investments in good faith.

Investment Valuation Inputs

Under ASC Topic 820, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For our portfolio securities, fair value is generally the amount that we might reasonably expect to receive upon the current sale of the security. Under ASC Topic 820, the fair value measurement assumes that the sale occurs in the principal market for the security, or in the absence of a principal market, in the most advantageous market for the security. Under ASC Topic 820, if no market for the security exists or if we do not have access to the principal market, the security should be valued based on the sale occurring in a hypothetical market. The securities in which we invest are generally only purchased and sold in merger and acquisition transactions, in which case the entire portfolio company is sold to a third-party purchaser. As a result, unless we have the ability to control such a transaction, the assumed principal market for our securities is a hypothetical secondary market. The level 3 inputs to our valuation process reflect management’s best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in a hypothetical secondary market.

Enterprise Value Waterfall Approach

In valuing equity securities (including warrants), we estimate fair value using an “Enterprise Value Waterfall” valuation model. We estimate the enterprise value of a portfolio company and then allocate the enterprise value to the portfolio company’s securities in order of their relative liquidation preference. In addition, the model assumes that any outstanding debt or other securities that are senior to our equity securities are required to be repaid at par.

To estimate the enterprise value of the portfolio company, we primarily use a valuation model based on a transaction multiple, which generally is the original transaction multiple, and measures of the portfolio company’s financial performance. In addition, we consider other factors, including but not limited to (i) offers from third-parties to purchase the portfolio company, (ii) the implied value of recent investments in the equity securities of the portfolio company, (iii) publicly available information regarding recent sales of private companies in comparable transactions and, (iv) when management believes there are comparable companies that are publicly traded, a review of these publicly traded companies and the market multiple of their equity securities.

The significant Level 3 inputs to the Enterprise Value Waterfall model are (i) an appropriate transaction multiple and (ii) a measure of the portfolio company’s financial performance, which generally is either earnings before interest, taxes, depreciation and amortization, as adjusted, or Adjusted EBITDA, or revenues. Such inputs can be based on historical operating results, projections of future operating results, or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. In determining the operating results input, we utilize the most recent portfolio company financial statements and forecasts available as of the valuation date. Management also consults with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Additionally, we consider some or all of the following factors:

| • |  | financial standing of the issuer of the security;

| • |  | comparison of the business and financial plan of the issuer with actual results;

| • |  | the size of the security held as it relates to the liquidity of the market for such security;

| • |  | pending public offering of common stock by the issuer of the security;

| • |  | pending reorganization activity affecting the issuer, such as merger or debt restructuring;

| • |  | ability of the issuer to obtain needed financing;

| • |  | changes in the economy affecting the issuer;

| • |  | financial statements and reports from portfolio company senior management and ownership;

65

##### Table of Contents

| • |  | the type of security, the security’s cost at the date of purchase and any contractual restrictions on the disposition of the security;

| • |  | special reports prepared by analysts;

| • |  | information as to any transactions or offers with respect to the security and/or sales to third parties of similar securities;

| • |  | the issuer’s ability to make payments and the type of collateral;

| • |  | the current and forecasted earnings of the issuer;

| • |  | statistical ratios compared to lending standards and to other similar securities; and

| • |  | other pertinent factors.

Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase in either the transaction multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher fair value for that security.

Income Approach

In valuing debt securities, we utilize an “Income Approach” model that considers factors including, but not limited to, (i) the stated yield on the debt security, (ii) the portfolio company’s current trailing twelve months, or TTM, Adjusted EBITDA as compared to the portfolio company’s historical or projected Adjusted EBITDA as of the date the investment was made and the portfolio company’s anticipated Adjusted EBITDA for the next twelve months of operations, (iii) the portfolio company’s current Leverage Ratio (defined as the portfolio company’s total indebtedness divided by Adjusted EBITDA) as compared to its Leverage Ratio as of the date the investment was made, (iv) publicly available information regarding current pricing and credit metrics for similar proposed and executed investment transactions of private companies and (v) when management believes a relevant comparison exists, current pricing and credit metrics for similar proposed and executed investment transactions of publicly traded debt. In addition, we use a risk rating system to estimate the probability of default on the debt securities and the probability of loss if there is a default. This risk rating system covers both qualitative and quantitative aspects of the business and the securities held.

We consider the factors above, particularly any significant changes in the portfolio company’s results of operations and leverage, and develop an expectation of the yield that a hypothetical market participant would require when purchasing the debt investment (the “Required Rate of Return”). The Required Rate of Return, along with the Leverage Ratio and Adjusted EBITDA are the significant Level 3 inputs to the Income Approach model. For investments where the Leverage Ratio and Adjusted EBITDA have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from management’s expectations as of the date the investment was made, and where there have been no significant fluctuations in the market pricing for such investments, we may conclude that the Required Rate of Return is equal to the stated rate on the investment and therefore, the debt security is appropriately priced. In instances where we determine that the Required Rate of Return is different from the stated rate on the investment, we discount the contractual cash flows on the debt instrument using the Required Rate of Return in order to estimate the fair value of the debt security.

Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Rate of Return or Leverage Ratio inputs for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in the Adjusted EBITDA input for a particular debt security may result in a higher (lower) fair value for that security.

The fair value of our royalty rights are calculated based on specific provisions contained in the pertinent operating or royalty agreements. The determination of the fair value of such royalty rights is not a significant component of our valuation process.

Revenue Recognition

Interest and Dividend Income

Interest income, adjusted for amortization of premium and accretion of original issue discount, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when interest and/or principal payments on a loan become past due, or if we otherwise do not expect the borrower to be able to service its debt and other obligations, we will place the loan on non-accrual status and will generally cease recognizing interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The cessation of recognition of such interest will negatively impact the reported fair value of the investment. We write off any previously accrued and uncollected interest when it is determined that interest is no longer considered collectible. Dividend income is recorded on the ex-dividend date.

We may have to include in our ICTI, interest income, including amortization of original issue discount, or OID, from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. As a result, we may be required to make a distribution to our stockholders in order to satisfy the minimum distribution requirements to maintain our RIC status, even though we will not have received and may not ever receive any corresponding cash amount. Additionally, any loss recognized by us for federal income tax purposes on previously accrued interest income will be treated as a capital loss.

Fee Income

Origination, facility, commitment, consent and other advance fees received in connection with loan agreements, or “loan origination fees,” are recorded as deferred income and recognized as investment income over the term of the loan. Upon prepayment of a loan, any unamortized loan origination fees are recognized as investment income. In the general course of our business, we receive certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received.

Payment-in-Kind Interest (PIK)

We currently hold, and we expect to hold in the future, some loans in our portfolio that contain a PIK interest provision. PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan, rather than being paid to us in cash, and is recorded as interest income. Thus, the actual collection of PIK interest may be deferred until the time of debt principal repayment.

To maintain our status as a RIC, PIK interest, which is a non-cash source of income, is included in our taxable income and therefore affects the amount we are required to pay to stockholders in the form of dividends, even though we have not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if we otherwise do not expect the borrower to be able to service its debt and other obligations, we will place the loan on non-accrual status and will generally cease recognizing PIK interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. We write off any accrued and uncollected PIK interest when it is determined that the PIK interest is no longer collectible.

We may have to include in our ICTI, PIK interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. As a result, we may be required to make a distribution to our stockholders in order to satisfy the minimum distribution requirements, even though we will not have received and may not ever receive any corresponding cash amount.

Recently Issued Accounting Standards

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, or ASU 2011-04. ASU 2011-04 clarifies the application of existing fair value measurement and disclosure requirements, changes the application of some requirements for measuring fair value and requires additional disclosure for fair value measurements categorized in Level 3 of the fair value hierarchy. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. We adopted this standard on January 1, 2012. The adoption of ASU 2011-04 did not have a material impact on our process for measuring fair values or on our financial statements, other than the inclusion of additional required disclosures.

Off-Balance Sheet Arrangements

We currently have no off-balance sheet arrangements.

Quantitative and Qualitative Disclosures About Market Risk

During 2011 and the first quarter of 2012, the United States economy continued to show modest improvements; however, during the third quarter of 2011, the financial markets experienced increased volatility and economic indicators suggested a further slowdown of the United States and European economies potentially leading to another recession. A prolonged slowdown in economic activity would likely have an adverse effect on a number of the industries in which some of our portfolio companies operate, and on certain of our portfolio companies as well. In addition, the recent sovereign debt crises may continue to impact the broader financial and credit markets and may continue to reduce the availability of debt and equity capital for the market as a whole and financial firms in particular.

During 2010, we experienced a $10.9 million increase in the fair value of our investment portfolio related to unrealized appreciation of investments. In 2011, we experienced a $6.4 million increase in the fair value of our investment portfolio related to unrealized appreciation of investments and in the first quarter of 2012, we experienced a slight increase of $0.6 million in the fair value of our investment portfolio related to unrealized appreciation of investments.

As of March 31, 2012, the fair value of our non-accrual assets was approximately $2.2 million, which comprised approximately 0.4% of the total fair value of our portfolio, and the cost of our non-accrual assets was approximately $6.0 million, or 1.1% of the total cost of our portfolio. We also had one asset as of March 31, 2012 that was on non-accrual with respect to the PIK interest component of the loan. Both the fair value and the cost of this asset as of March 31, 2012 was approximately $5.2 million, which comprised approximately 1.0% of both the total fair value of our portfolio and the cost of our portfolio. In addition to these non-accrual assets, as of March 31, 2012, we had, on a fair value basis, approximately $23.8 million of debt investments, or 4.4% of the total fair value of our portfolio, which were current with respect to scheduled principal and interest payments, but which were carried at less than cost. The cost of these assets as of March 31, 2012 was approximately $31.4 million, or 5.9% of the total cost of our portfolio.

The volatile and stressed conditions of the equity and debt markets may continue for a prolonged period of time or worsen in the future. To the extent that recessionary conditions recur, the economy remains stagnate, any further downgrades to the U.S. government’s sovereign credit rating occur, the European credit crisis continues, or the economy fails to return to pre-recession levels, the financial position and results of operations of certain of the middle-market companies in our portfolio could be further affected adversely, which ultimately could lead to difficulty in our portfolio companies meeting debt service requirements and lead to an increase in defaults. There can be no assurance that the performance of our portfolio companies will not be further impacted by economic conditions, which could have a negative impact on our future results.

In addition, we are subject to interest rate risk. Interest rate risk is defined as the sensitivity of our current and future earnings to interest rate volatility, variability of spread relationships, the difference in re-pricing intervals between our assets and liabilities and the effect that interest rates may have on our cash flows. Changes in the general level of interest rates can affect our net interest income, which is the difference between the interest income earned on interest earning assets and our interest expense incurred in connection with our interest-bearing debt and liabilities. Changes in interest rates can also affect, among other things, our ability to acquire and originate loans and securities and the value of our investment portfolio. Our investment income is affected by fluctuations in various interest rates, including LIBOR and prime rates. We regularly measure exposure to interest rate risk and determine whether or not any hedging transactions are necessary to mitigate exposure to changes in interest rates. As of March 31, 2012, we were not a party to any hedging arrangements.

As of March 31, 2012, approximately 96.5%, or $469.1 million (at cost) of our debt portfolio investments bore interest at fixed rates and approximately 3.5%, or $16.9 million (at cost) of our debt portfolio investments bore interest at variable rates, which are either Prime-based or LIBOR-based. A 200 basis point increase or decrease in the interest rates on our variable-rate debt investments would increase or decrease, as applicable, our investment income by approximately $0.3 million on an annual basis. All of our pooled SBA-guaranteed debentures and our Senior Notes bear interest at fixed rates. Our Credit Facility bears interest, subject to our election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or (ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of (i) prime rate, (ii) the federal funds rate plus 0.5% or (iii) the adjusted one-month LIBOR plus 2.0%.

Because we currently borrow, and plan to borrow in the future, money to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds and the rate at which we invest the funds borrowed. Accordingly, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. In periods of rising interest rates, our cost of funds would increase, which could reduce our net investment income if there is not a corresponding increase in interest income generated by our investment portfolio.

Related Party Transactions

During the three years ending December 31, 2011 and the three months ended March 31, 2012, there were no related party transactions between Triangle Capital Corporation and any of its subsidiaries.

BUSINESS

Triangle Capital Corporation is a specialty finance company that provides customized financing to lower middle market companies located throughout the United States. We define lower middle market companies as those having annual revenues between $10.0 million and $250.0 million. Our goal is to be the premier provider of capital to these companies. Our investment objective is to seek attractive returns by generating current income from our debt investments and capital appreciation from our equity related investments. Our investment philosophy is to partner with business owners, management teams and financial sponsors to provide flexible financing solutions to fund growth, changes of control, or other corporate events. We invest primarily in subordinated debt securities secured by second lien security interests in portfolio company assets, coupled with equity interests. On a more limited basis, we also invest in senior debt securities secured by first lien security interests in portfolio companies.

We focus on investments in companies with a history of generating revenues and positive cash flow, an established market position and a proven management team with a strong operating discipline. Our target portfolio company has annual revenues between $20.0 and $200.0 million and EBITDA between $3.0 and $20.0 million. We believe that these companies have less access to capital and that the market for such capital is underserved relative to larger companies. Companies of this size are generally privately held and are less well known to traditional capital sources such as commercial and investment banks.

Our investments generally range from $5.0 to $25.0 million per portfolio company. In certain situations, we have partnered with other funds to provide larger financing commitments. We are continuing to operate Triangle SBIC and Triangle SBIC II as SBICs and to utilize the proceeds of the sale of SBA guaranteed debentures, referred to herein as SBA leverage, to enhance returns to our stockholders. As of March 31, 2012, we had investments in 66 portfolio companies, with an aggregate cost of $534.9 million.

Our Business Strategy

We seek attractive returns by generating current income from our debt investments and capital appreciation from our equity related investments by:

| • |  | 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.

| • |  | Focusing on Underserved Markets. The lower middle market has traditionally been underserved. 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 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 attractiveness, which we believe allows 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 participating in regular meetings of the portfolio company’s board of directors. We believe that our initial and ongoing portfolio review process allows us to effectively monitor 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.

Our Investment Criteria

We utilize the following criteria and guidelines in evaluating investment opportunities. However, not all of these criteria and guidelines have been, or will be, met in connection with each of our investments.

| • |  | 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.

73

##### Table of Contents

| • |  | 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.

Investments

Debt Investments

We tailor the terms of our debt investments to the facts and circumstances of each transaction and prospective portfolio company, negotiating a structure that seeks to protect our rights and manage our risk while creating incentives for the portfolio company to achieve its business plan. To that end, we typically seek board observation rights with each of our portfolio companies and offer managerial assistance. We also seek to limit the downside risks of our investments by negotiating covenants that are designed to protect our investments while affording our portfolio companies as much flexibility in managing their businesses as possible. Such restrictions may include affirmative and negative covenants, default penalties, lien protection, change of control provisions and put rights. We typically add a prepayment penalty structure to enhance our total return on our investments.

We primarily invest in subordinated notes and invest in senior secured debt on a more limited basis. Subordinated notes are junior to senior secured debt. Our subordinated debt investments and senior secured debt investments generally have terms of three to seven years, do not have scheduled amortization and are due at maturity. Our subordinated debt investments generally provide for fixed interest rates between 12.0% and 17.0% per annum and our senior secured debt investments generally provide for variable interest at rates ranging from LIBOR plus 350 basis points to LIBOR plus 950 basis points per annum. Our subordinated debt investments generally are secured by a second priority security interest in the assets of the borrower and generally include an equity component, such as warrants to purchase common stock in the portfolio company. In addition, certain loan investments may have a form of interest that is not paid currently but is accrued and added to the loan balance and paid at the end of the term, referred to as payment in kind (“PIK”) interest. In our negotiations with potential portfolio companies, we generally seek to minimize PIK interest as we have to pay out such accrued interest as distributions to our stockholders, and we may have to borrow money or raise additional capital in order to meet the requirement of generally having to pay out at least 90.0% of our taxable income to continue to qualify as a Regulated Investment Company, or RIC, for U.S. federal income tax purposes. At March 31, 2012, the weighted average yield on our outstanding debt investments other than non-accrual debt investments (including PIK interest) was approximately 15.1%, the weighted average yield on all of our outstanding investments (including equity and equity-linked investments but excluding non-accrual debt investments) was approximately 14.0% and the weighted average yield on all of our outstanding investments (including equity and equity-linked investments and non-accrual debt investments) was approximately 13.8%.

An SBIC may make investments in the form of straight loans (“Loans”), debt with equity features (“Debt Securities”), or equity securities. Loans and Debt Securities must be issued for a term of not less than one year (except for bridge loans in anticipation of a permanent financing in which the SBIC intends to participate, or to protect its prior investment) and must have amortization not exceeding “straight line.” The permissible interest rate on Loans is the higher of (i) 19% or (ii) 11% over the higher of the SBIC’s weighted cost of debenture leverage or the current debenture rate. For Debt Securities, the permitted rate is the higher of (i) 14% or (ii) 6% over the higher of the SBIC’s weighted cost of debenture leverage or the current debenture rate. If a financing is in default, these maximums may increase by up to 7%. SBA Regulations define an SBIC’s weighted cost of debenture leverage and describe the permitted rate when more than one SBIC participates in the financing.

Equity Investments

When we provide financing, we often acquire equity interests in the portfolio company. We generally seek to structure our equity investments as non-control investments to provide us with minority rights and event-driven or time-driven puts. We also seek to obtain registration rights in connection with these investments, which

74

##### Table of Contents

may include demand and “piggyback” registration rights, board seats and board observation rights. Our investments have in the past and may in the future contain a synthetic equity position pursuant to a formula typically setting forth royalty rights we may exercise in accordance with such formula.

Investment Committees

Triangle Capital Corporation has an investment committee that is responsible for all aspects of our investment process relating to investments made by Triangle Capital Corporation or any of its subsidiaries, other than investments made by Triangle SBIC and Triangle SBIC II. The members of the Triangle Capital Corporation investment committee are Messrs. Garland S. Tucker, III, Brent P.W. Burgess, Steven C. Lilly, Jeffrey A. Dombcik, Douglas A. Vaughn, Cary B. Nordan and David F. Parker.

Triangle SBIC has an investment committee that is responsible for all aspects of our investment process relating to investments made by Triangle SBIC. The members of Triangle SBIC’s investment committee are Messrs. Garland S. Tucker, III, Brent P.W. Burgess, Steven C. Lilly, Jeffrey A. Dombcik, Douglas A. Vaughn, Cary B. Nordan and David F. Parker.

Triangle SBIC II has an investment committee that is responsible for all aspects of our investment process relating to investments made by Triangle SBIC II. The members of Triangle SBIC II’s investment committee are Messrs. Garland S. Tucker, III, Brent P.W. Burgess, Steven C. Lilly, Jeffrey A. Dombcik, Douglas A. Vaughn, and Cary B. Nordan. For purposes of the discussion herein, any reference to the “investment committee” refers to the investment committee of Triangle Capital Corporation, the investment committee of Triangle SBIC and the investment committee of Triangle SBIC II.

Investment Process

Our investment committee meets once a week and also meets on an as needed basis depending on transaction volume. Our investment committee has organized our investment process into five distinct stages:

| • |  | Origination

| • |  | Due Diligence and Underwriting

| • |  | Approval

| • |  | Documentation and Closing

| • |  | Portfolio Management and Investment Monitoring

75

##### Table of Contents

Our investment process is summarized in the following chart:

Origination

The origination process for our investments includes sourcing, screening, preliminary due diligence, transaction structuring, and negotiation. Our investment professionals utilize their extensive relationships with various financial sponsors, entrepreneurs, attorneys, accountants, investment bankers and other non-bank providers of capital to source transactions with prospective portfolio companies.

If a transaction meets our investment criteria, we perform preliminary due diligence, taking into consideration some or all of the following factors:

| • |  | A comprehensive financial model that we prepare based on quantitative analysis of historical financial performance, financial projections and pro forma financial ratios assuming investment;

| • |  | Competitive landscape surrounding the potential investment;

| • |  | Strengths and weaknesses of the potential investment’s business strategy and industry;

| • |  | Results of a broad qualitative analysis of the company’s management team, products or services, market position, market dynamics and customers and suppliers; and

| • |  | Potential investment structures, certain financing ratios and investment pricing terms.

If the results of our preliminary due diligence are satisfactory, the origination team prepares a Summary Transaction Memorandum, which is presented to our investment committee. If our investment committee recommends moving forward, we issue a non-binding term sheet to the potential portfolio company. Upon execution of a term sheet, we begin our formal due diligence and underwriting process as we move toward investment approval.

76

##### Table of Contents

Due Diligence and Underwriting

Our due diligence on a prospective investment is completed by a minimum of two investment professionals, which we refer to as the underwriting team. The members of the underwriting team work together to conduct due diligence and to understand the relationships among the prospective portfolio company’s business plan, operations and financial performance through various methods, including, among others, on-site visits with management, in-depth review of historical and projected financial data, interviews with customers and suppliers, management background checks, third-party accounting reports and review of any material contracts.

In most circumstances, we utilize outside experts to review the legal affairs, accounting systems, and, where appropriate, we engage specialists to investigate issues like environmental matters and general industry outlooks. During the underwriting process, significant attention is given to sensitivity analyses and how companies might be expected to perform in a protracted “downside” operating environment. In addition, we analyze key financing ratios and other industry metrics, including total debt to EBITDA, EBITDA to fixed charges, EBITDA to total interest expense, total debt to total capitalization and total senior debt to total capitalization.

Upon completion of a satisfactory due diligence review and as part of our evaluation of a proposed investment, the underwriting team prepares an Investment Memorandum for presentation to our investment committee. The Investment Memorandum includes information about the potential portfolio company such as its history, business strategy, potential strengths and risks involved, analysis of key customers and suppliers, third party consultant findings, expected returns on investment structure, anticipated sources of repayment and exit strategies, analysis of historical financials, and potential capitalization and ownership.

Approval

The underwriting team for the proposed investment presents the Investment Memorandum to our investment committee for consideration and approval. After reviewing the Investment Memorandum, members of the investment committee may request additional due diligence or modify the proposed financing structure or terms of the proposed investment. Before we proceed with any investment, the investment committee must approve the proposed investment. Upon receipt of transaction approval, the underwriting team proceeds to document the transaction.

Documentation and Closing

The underwriting team is responsible for all documentation related to investment closings. In addition, we rely on law firms with whom we have worked on multiple transactions to help us complete the necessary documentation associated with transaction closings. If a transaction changes materially from what was originally approved by the investment committee, the underwriting team requests a formal meeting of the investment committee to communicate the contemplated changes. The investment committee has the right to approve the amended transaction structure, to suggest alternative structures or not to approve the contemplated changes.

Portfolio Management and Investment Monitoring

Our investment professionals generally employ several methods of evaluating and monitoring the performance of our portfolio companies, which, depending on the particular investment, may include the following specific processes, procedures and reports:

| • |  | Monthly and quarterly review of actual financial performance versus the corresponding period of the prior year and financial projections;

| • |  | Monthly and quarterly monitoring of all financial and other covenants;

| • |  | Review of senior lender loan compliance certificates, where applicable;

77

##### Table of Contents

| • |  | Quarterly review of operating results, and general business performance, including the preparation of a portfolio monitoring report which is distributed to members of our investment committee;

| • |  | Periodic face-to-face meetings with management teams and financial sponsors of portfolio companies;

| • |  | Attendance at portfolio company board meetings through board seats or observation rights; and

| • |  | Application of our investment rating system to each investment.

In the event that our investment committee determines that an investment is underperforming, or circumstances suggest that the risk associated with a particular investment has significantly increased, we undertake more aggressive monitoring of the affected portfolio company. The level of monitoring of an investment is determined by a number of factors, including, but not limited to, trends in the financial performance of the portfolio company, the investment structure and the type of collateral securing our investment, if any.

Investment Rating System

We monitor a wide variety of key credit statistics that provide information regarding our portfolio companies to help us assess credit quality and portfolio performance. We generally require our portfolio companies to have annual financial audits in addition to monthly and quarterly unaudited financial statements. Using these statements, we calculate and evaluate certain financing ratios. For purposes of analyzing the financial performance of our portfolio companies, we may make certain adjustments to their financial statements to reflect the pro forma results of the portfolio company consistent with a change of control transaction, to reflect anticipated cost savings resulting from a merger or restructuring, costs related to new product development, compensation to previous owners, and other acquisition or restructuring related items.

As part of our valuation procedures we assign an investment rating to all of our investments in debt securities. Our investment rating system uses a scale of 0 to 10, with 10 being the lowest probability of default and principal loss. This system is used to estimate the probability of default on our debt securities and the probability of loss if there is a default. The system is also used to assist us in estimating the fair value of equity related securities. These types of systems are referred to as risk rating systems and are also used by banks and rating agencies. Our risk rating system covers both qualitative and quantitative aspects of the business and the securities we hold.

78

##### Table of Contents

Each portfolio company debt investment is rated based upon the following numeric investment rating system:

Investment Rating |  | Description
10 |  | Investment is performing above original expectations and possibly 30.0% or more above original projections provided by the portfolio company. Investment has been positively influenced by an unforeseen external event. Full return of principal and interest is expected. Capital gain is expected.
9 |  | Investment is performing above original expectations and possibly 30.0% or more above original projections provided by the portfolio company. Investment may have been or is soon to be positively influenced by an unforeseen external event. Full return of principal and interest is expected. Capital gain is expected.
8 |  | Investment is performing above original expectations and possibly 21.0% to 30.0% above original projections provided by the portfolio company. Full return of principal and interest is expected. Capital gain is expected.
7 |  | Investment is performing above original expectations and possibly 11.0% to 20.0% above original projections provided by the portfolio company. Full return of principal and interest is expected. Depending on age of transaction, potential for capital gain exists.
6 |  | Investment is performing above original expectations and possibly 5.0% to 10.0% above original projections provided by the portfolio company. Full return of principal and interest is expected. Depending on age of transaction, potential for capital gain exists.
5 |  | Investment is performing in line with original expectations. Full return of principal and interest is expected. Depending on age of transaction, potential for capital gain may be expected.
4 |  | Investment is performing below original expectations, but no covenant defaults have occurred. Full return of principal and interest is expected. Potential for capital gain may still be expected.
3 |  | Investment is in default of transaction covenants but interest payments are current. No loss of principal is expected.
2 |  | Investment is in default of transaction covenants and interest (and possibly principal) payments are not current. A principal loss of between 1.0% and 33.0% is expected.
1 |  | Investment is in default of transaction covenants and interest (and possibly principal) payments are not current. A principal loss of between 34.0% and 67.0% is expected.
0 |  | Investment is in default and a principal loss of between 68.0% and 100.0% is expected.

Valuation Process and Determination of Net Asset Value

Valuation Process

The most significant estimate inherent in the preparation of our financial statements is the valuation of investments and the related amounts of unrealized appreciation and depreciation of investments recorded. We have established and documented processes and methodologies for determining the fair values of portfolio company investments on a recurring basis in accordance with the 1940 Act and FASB ASC Topic 820, Fair Value Measurements and Disclosures, or ASC Topic 820. Under ASC Topic 820, a financial instrument is categorized within the ASC Topic 820 valuation hierarchy based upon the lowest level of input to the valuation process that is significant to the fair value measurement. The three levels of valuation inputs established by ASC Topic 820 are as follows:

Level 1 Inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 Inputs — include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

79

##### Table of Contents

Level 3 Inputs — include inputs that are unobservable and significant to the fair value measurement.

Our investment portfolio is comprised of debt and equity instruments of privately held companies for which quoted prices or other inputs falling within the categories of Level 1 and Level 2 are not available. Therefore, we determine the fair value of our investments in good faith using level 3 inputs, pursuant to a valuation policy and process that is established by our management with the assistance of certain third-party advisors and subsequently approved by our Board of Directors. There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. The recorded fair values of our investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned. For a discussion of the risks inherent in determining the value of securities for which readily available market values do not exist, see “Risk Factors — Risks Relating to Our Business and Structure — Our investment portfolio is and will continue to be recorded at fair value as determined in good faith by our Board of Directors and, as a result, there is and will continue to be uncertainty as to the value of our portfolio investments.”

Our valuation process is led by our executive officers and managing directors. The valuation process begins with a quarterly review of each investment in our investment portfolio by our executive officers and our investment committee. Valuations of each portfolio security are then prepared by our investment professionals, who have direct responsibility for the origination, management and monitoring of each investment. Under our valuation policy, each investment valuation is subject to (i) a review by the lead investment officer responsible for the portfolio company investment and (ii) a peer review by a second investment officer or executive officer. Generally, any investment that is valued below cost is subjected to review by one of our executive officers. After the peer review is complete, we engage Duff & Phelps, LLC (“Duff & Phelps”), an independent valuation firm, to provide a third-party review of certain investments, as described further below. In addition, all investment valuations are provided to our independent registered public accounting firm in connection with quarterly review procedures and the annual audit of our financial statements. Finally, the Board of Directors has the responsibility for reviewing and approving, in good faith, the fair value of our investments in accordance with the 1940 Act.

Duff & Phelps provides third party valuation consulting services to us which consist of certain limited procedures that we identified and requested Duff & Phelps to perform (hereinafter referred to as the “procedures”). We generally requests Duff & Phelps to perform the procedures on each portfolio company at least once in every calendar year and for new portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In addition, we generally requests Duff & Phelps to perform the procedures on a portfolio company when there has been a significant change in the fair value of the investment. In certain instances, we may determine that it is not cost-effective, and as a result is not in our stockholders’ best interest, to request Duff & Phelps to perform the procedures on one or more portfolio companies. Such instances include, but are not limited to, situations where the fair value of the investment in the portfolio company is determined to be insignificant relative to the total investment portfolio. For a further discussion of Duff & Phelps’ procedures, see the section entitled “Investment Valuation” included in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Investment Valuation Inputs

Under ASC Topic 820, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For our portfolio securities, fair value is generally the amount that we might reasonably expect to receive upon the current sale of the security. Under ASC Topic 820, the fair value measurement assumes that the sale occurs in the principal market for the security, or in the absence of a principal market, in the most advantageous market for the security. Under ASC Topic 820, if no market for the security exists or if we do not have access to the principal market, the security should be valued based on the sale occurring in a hypothetical market. The securities in which we invest

80

##### Table of Contents

are generally only purchased and sold in merger and acquisition transactions, in which case the entire portfolio company is sold to a third-party purchaser. As a result, unless we have the ability to control such a transaction, the assumed principal market for our securities is a hypothetical secondary market. The level 3 inputs to our valuation process reflect management’s best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in a hypothetical secondary market.

Enterprise Value Waterfall Approach

In valuing equity securities (including warrants), we estimate fair value using an “Enterprise Value Waterfall” valuation model. We estimate the enterprise value of a portfolio company and then allocate the enterprise value to the portfolio company’s securities in order of their relative liquidation preference. In addition, the model assumes that any outstanding debt or other securities that are senior to our equity securities are required to be repaid at par.

To estimate the enterprise value of the portfolio company, we primarily use a valuation model based on a transaction multiple, which generally is the original transaction multiple, and measures of the portfolio company’s financial performance. In addition, we consider other factors, including but not limited to (i) offers from third-parties to purchase the portfolio company, (ii) the implied value of recent investments in the equity securities of the portfolio company, (iii) publicly available information regarding recent sales of private companies in comparable transactions and, (iv) when management believes there are comparable companies that are publicly traded, a review of these publicly traded companies and the market multiple of their equity securities.

The significant Level 3 inputs to the Enterprise Value Waterfall model are (i) an appropriate transaction multiple and (ii) a measure of the portfolio company’s financial performance, which generally is either earnings before interest, taxes, depreciation and amortization, as adjusted, or Adjusted EBITDA, or revenues. Such inputs can be based on historical operating results, projections of future operating results, or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. In determining the operating results input, we utilize the most recent portfolio company financial statements and forecasts available as of the valuation date. Management also consults with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Additionally, we consider some or all of the following factors:

| • |  | financial standing of the issuer of the security;

| • |  | comparison of the business and financial plan of the issuer with actual results;

| • |  | the size of the security held as it relates to the liquidity of the market for such security;

| • |  | pending public offering of common stock by the issuer of the security;

| • |  | pending reorganization activity affecting the issuer, such as merger or debt restructuring;

| • |  | ability of the issuer to obtain needed financing;

| • |  | changes in the economy affecting the issuer;

| • |  | financial statements and reports from portfolio company senior management and ownership;

| • |  | the type of security, the security’s cost at the date of purchase and any contractual restrictions on the disposition of the security;

| • |  | special reports prepared by analysts;

| • |  | information as to any transactions or offers with respect to the security and/or sales to third parties of similar securities;

| • |  | the issuer’s ability to make payments and the type of collateral;

81

##### Table of Contents

| • |  | the current and forecasted earnings of the issuer;

| • |  | statistical ratios compared to lending standards and to other similar securities; and

| • |  | other pertinent factors.

Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase in either the transaction multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher fair value for that security.

Income Approach

In valuing debt securities, we utilize an “Income Approach” model that considers factors including, but not limited to, (i) the stated yield on the debt security, (ii) the portfolio company’s current trailing twelve months, or TTM Adjusted EBITDA as compared to the portfolio company’s historical or projected Adjusted EBITDA as of the date the investment was made and the portfolio company’s anticipated Adjusted EBITDA for the next twelve months of operations, (iii) the portfolio company’s current Leverage Ratio (defined as the portfolio company’s total indebtedness divided by Adjusted EBITDA) as compared to its Leverage Ratio as of the date the investment was made, (iv) publicly available information regarding current pricing and credit metrics for similar proposed and executed investment transactions of private companies and (v) when management believes a relevant comparison exists, current pricing and credit metrics for similar proposed and executed investment transactions of publicly traded debt. In addition, we use a risk rating system to estimate the probability of default on the debt securities and the probability of loss if there is a default. This risk rating system covers both qualitative and quantitative aspects of the business and the securities held.

We consider the factors above, particularly any significant changes in the portfolio company’s results of operations and leverage, and develop an expectation of the yield that a hypothetical market participant would require when purchasing the debt investment (the “Required Rate of Return”). The Required Rate of Return, along with the Leverage Ratio and Adjusted EBITDA are the significant Level 3 inputs to the Income Approach model. For investments where the Leverage Ratio and Adjusted EBITDA have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from management’s expectations as of the date the investment was made, and where there have been no significant fluctuations in the market pricing for such investments, we may conclude that the Required Rate of Return is equal to the stated rate on the investment and therefore, the debt security is appropriately priced. In instances where we determine that the Required Rate of Return is different from the stated rate on the investment, we discount the contractual cash flows on the debt instrument using the Required Rate of Return in order to estimate the fair value of the debt security.

Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Rate of Return or Leverage Ratio inputs for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in the Adjusted EBITDA input for a particular debt security may result in a higher (lower) fair value for that security.

The fair value of our royalty rights are calculated based on specific provisions contained in the pertinent operating or royalty agreements. The determination of the fair value of such royalty rights is not a significant component of our valuation process.

Quarterly Net Asset Value Determination

We determine the net asset value per share of our common stock on at least a quarterly basis, and more frequently if we are required to do so pursuant to an equity offering or pursuant to federal laws and regulations. The net asset value per share is equal to the value of our total assets minus total liabilities and any preferred stock outstanding divided by the total number of shares of common stock outstanding.

Managerial Assistance

As a BDC, we offer, and must provide upon request, managerial assistance to certain of our portfolio companies. This assistance typically involves, among other things, monitoring the operations of our portfolio companies, participating in board and management meetings, consulting with and advising officers of portfolio companies and providing other organizational and financial guidance. Our senior management team provides such services. We believe, based on our management team’s combined experience at investment banks, commercial banks, and operating in executive-level capacities in various operating companies, we offer this assistance effectively. We generally receive fees for these services.

Competition

We compete for investments with a number of investment funds (including private equity funds, mezzanine funds and other SBICs) and BDCs, as well as traditional financial services companies such as commercial banks and other sources of financing. Many of these entities have greater financial and managerial resources than we do. We believe we compete with these entities primarily on the basis of our willingness to make smaller investments, 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 that are comparable to or lower than the rates we offer. Therefore, we do not seek to compete primarily on the interest rates we offer to potential portfolio companies.

Our competitors also do not always require equity components in their investments. For additional information concerning the competitive risks we face, see “Risk Factors — Risks Relating to Our Business and Structure — We operate in a highly competitive market for investment opportunities”.

Employees

At March 31, 2012, we employed 20 individuals, including investment and portfolio management professionals, operations professionals and administrative staff. We expect to expand our management team and administrative staff in the future in proportion to our growth.

Properties

We do not own any real estate or other physical properties materially important to our operation or any of our subsidiaries. Currently, we lease approximately 11,027 square feet of office space located at 3700 Glenwood Avenue, Suite 530, Raleigh, North Carolina 27612. We believe that our current facilities are adequate for our business as we intend to conduct it.

Legal Proceedings

Although we may, from time to time, be involved in litigation arising out of our operations in the normal course of business or otherwise, neither we nor any of our subsidiaries are currently a party to any pending material legal proceedings.

Compensation Committee

The Compensation Committee is appointed by the Board to discharge its responsibilities relating to the compensation of our independent directors, executive officers and other key employees. The Compensation Committee has the responsibility for recommending appropriate compensation levels for our executive officers, evaluating and approving executive officer compensation plans, policies and programs, reviewing benefit plans for executive officers and other employees and producing an annual report on executive compensation for inclusion in our proxy statement. The Compensation Committee may form and delegate any of its responsibilities to a subcommittee so long as such subcommittee is solely composed of one or more members of the Compensation Committee. The Compensation Committee Charter is available under “Corporate Governance” on the Investor Relations section of our website at the following URL: http://ir.tcap.com.

Members of our Compensation Committee review annually and approve goals and objectives relevant to our executive officers’ compensation, including annual performance objectives. They evaluate annually the performance of the chief executive officer and other executive officers, and recommend to the independent directors of the Board the compensation level for each such person based on this evaluation. They review on a periodic basis our executive compensation programs to determine whether they are properly coordinated and achieve their intended purposes. They review and recommend to the Board for approval any changes in incentive compensation plans and equity-based compensation plans. The members of the Compensation Committee review and approve all equity-based compensation plans of Triangle, whether or not final approval rests with the Company’s stockholders, and grant equity-based awards pursuant to such plans in compliance with the 1940 Act. They review and approve compensation packages, including any special supplemental benefits or perquisites for our executive officers. They review employee compensation strategies, including salary levels and ranges and employee fringe benefits, as well as compensation consultants’ analyses and various industry comparables including both public and private investment funds that operate and invest in a manner similar to the Company.

In determining executive compensation levels for our executive officers, the Compensation Committee meets at least annually with management, and may meet with independent compensation consultants, in order to determine whether current methods of executive compensation are effective in achieving Triangle’s short and long term strategies. The Compensation Committee, in conjunction with a compensation consultant if necessary, will analyze the compensation of executive officers and directors of other BDCs in order to establish the compensation levels necessary to attract and retain quality executive officers and investment professionals. In 2011, the Compensation Committee engaged McLagan, an independent compensation consultant, to advise the Compensation Committee on these matters. For more information regarding the role of Triangle’s management in determining compensation, please see the discussion in “Compensation Discussion & Analysis — Establishing Compensation Levels — Role of the Compensation Committee and Management.”

The members of the Compensation Committee are Messrs. Dunwoody, Goldstein and Smith, each of whom is independent for purposes of Section 2(a)(19) of the 1940 Act and the applicable NYSE corporate governance listing standards.

COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS

DIRECTOR COMPENSATION

Our directors are divided into two groups — interested directors and independent directors. Interested directors are “interested persons” as defined in Section 2(a)(19) of the 1940 Act. The compensation table below sets forth compensation that our independent directors earned during the year ended December 31, 2011. Our interested directors are not compensated for their service as Board members.

(1) | Grant date fair value of restricted stock awards granted to each non-employee director on May 4, 2011. SEC disclosure rules require reporting of the aggregate grant date fair value computed in accordance with Financial Accounting Standards Board or FASB, Accounting Standards Codification, or ASC, Topic 718, or FASB ASC Topic 718, Compensation — Stock Compensation.

Director Fees

For fiscal year 2011, each non-employee member of the Board of Directors was paid a $20,000 annual cash retainer fee. Also in 2011, each of our non-employee directors earned an annual fee of $30,000 worth of our restricted stock, calculated based on the share price of our common stock as of the close of the NYSE on May 4, 2011, the date of grant. Based on this calculation, each of our independent directors received 1,679 shares of restricted stock, which vested on May 4, 2012. These restricted stock grants historically have occurred on the date of our annual stockholders meeting.

In addition, independent directors receive a fee of $2,500 for each Board meeting attended in person and $1,250 for each Board meeting attended by conference telephone or similar communications equipment; Audit Committee members receive a fee of $1,500 for each Audit Committee meeting attended in person and $750 for each Audit Committee meeting attended by conference telephone or similar communication equipment; and members of our Compensation Committee and Nominating and Corporate Governance Committee receive a fee of $1,000 for each committee meeting attended in person and $500 for each committee meeting attended by conference telephone or similar communication equipment. Finally, our Audit Committee chairman receives an annual fee of $20,000, our Compensation Committee chairman receives an annual fee of $10,000 and our Nominating and Corporate Governance Committee chairman receives an annual fee of $5,000 for their services as chairmen of their respective committees. We also reimburse our independent directors for all reasonable direct out-of-pocket expenses occurred in connection with their service on the Board. Directors who are also our employees or employees of our subsidiaries do not receive compensation for their services as directors.

Non-Employee Director Equity Compensation

Our Board of Directors and sole stockholder approved Triangle’s 2007 Equity Incentive Plan, or the Original Plan, effective February 13, 2007, for the purpose of attracting and retaining the services of executive officers, directors and other key employees. During our fiscal year ended December 31, 2007, no equity incentive awards were granted under the Original Plan, in part due to certain 1940 Act restrictions which disallow the issuance of certain types of compensation to a business development company’s employees and non-employee directors without having first obtained exemptive relief. In 2007, we filed a request with the Securities and Exchange Commission, or the SEC, for such exemptive relief with respect to our ability to issue restricted stock to our employees and non-employee directors. On March 18, 2008 we received an order from the SEC

108

##### Table of Contents

authorizing such issuance of restricted stock to our employees and non-employee directors pursuant to the terms of the Triangle Capital Corporation Amended and Restated 2007 Equity Incentive Plan, or the Amended and Restated Plan or the Equity Incentive Plan, and as otherwise set forth in the exemptive order. In 2008, our Board approved, and at the 2008 Annual Stockholders Meeting the stockholders voted to approve, the Amended and Restated Plan. During our fiscal year ended December 31, 2011, we granted restricted share awards to our officers, directors and key employees as compensation related to performance in 2010. In 2012, our Board approved, and at the 2012 Annual Stockholders Meeting the stockholders voted to approve, an increase in the number of shares available for issuance under the Amended and Restated Plan. Up to 2,400,000 shares are currently available for issuance under the Amended and Restated Plan.

The Equity Incentive Plan provides that our non-employee directors each receive an automatic grant of restricted stock at the beginning of each one-year term of service on the Board, for which forfeiture restrictions lapse one year from the grant date. The grants of restricted stock to non-employee directors under the Equity Incentive Plan will be automatic (that is, the grants will be equal to $30,000 worth of restricted stock each year), and the terms thereunder will not be changed without SEC approval. Shares granted pursuant to a restricted stock award will not be transferable until such shares have vested in accordance with the terms of the award agreement, unless the transfer is by will or by the laws of descent and distribution.

The following is a summary of the material features of the Amended and Restated Plan. It may not contain all of the information important to you. The Amended and Restated Plan includes provisions allowing the issuance of restricted stock to all key employees and directors. Restricted stock refers to an award of stock that is subject to forfeiture restrictions and may not be transferred until such restrictions have lapsed. The Amended and Restated Plan will also allow us to issue options to our key employees in the future should our Board and compensation committee choose to do so.

Under the Amended and Restated Plan, up to 2,400,000 shares of our common stock are currently authorized for issuance. Participants in the Amended and Restated Plan who are employees and employee directors may receive awards of options to purchase shares of common stock or grants of restricted stock, as determined by the Board. Participants who are non-employee directors may receive awards of restricted stock in accordance with certain parameters as discussed below. The basis of such participation is to provide incentives to our employees and directors in order to attract and retain the services of qualified professionals.

Options granted under the Amended and Restated Plan entitle the optionee, upon exercise, to purchase shares of common stock at a specified exercise price per share. Options must have a per share exercise price of no less than the fair market value of a share of stock on the date of the grant, subject to forfeiture provisions as determined by the Board. The exercise period of each stock option awarded will expire on a date determined by the Board, such date to be specified in the stock option award agreement; however, the Plan also states that no stock option award will be exercisable after the expiration of ten years from the date such stock option was granted.

The Amended and Restated Plan permits the issuance of restricted stock to employees and directors consistent with such terms and conditions as the Board shall deem appropriate, subject to the limitations set forth in the Plan. With respect to awards issued to our employees and officers, the Board will determine the time or times at which such shares of restricted stock will become exercisable and the terms on which such shares will remain exercisable. Shares granted pursuant to a restricted stock award will not be transferable until such shares have vested in accordance with the terms of the award agreement, unless the transfer is by will or by the laws of descent and distribution.

The Amended and Restated Plan provides that our non-employee directors each receive an automatic grant of restricted stock at the beginning of each one-year term of service on the Board, for which forfeiture restrictions lapse one year from the grant date. The number of shares granted to each non-employee director in 2011 was the equivalent of $30,000 worth of shares, taken at the market value at the close of the NYSE on the date of grant, which historically has been the date of our annual stockholders meeting. The grants of restricted stock to non-employee directors under the Amended and Restated Plan will be automatic (that is, the grants will

equal $30,000 worth of restricted stock each year), and the terms thereunder will not be changed without SEC approval. Shares granted pursuant to a restricted stock award will not be transferable until such shares have vested in accordance with the terms of the award agreement, unless the transfer is by will or by the laws of descent and distribution.

Our Board of Directors has delegated administration of the Amended and Restated Plan to the Compensation Committee, currently comprised solely of three (3) independent directors who are independent pursuant to the listing requirements of the NYSE. Our Board may abolish such committee at any time and revest in our Board the administration of the Amended and Restated Plan. Our Board administers the Amended and Restated Plan in a manner that is consistent with the applicable requirements of the NYSE and the exemptive order.

EXECUTIVE COMPENSATION

General

In 2011, our senior management team consisted of Garland S. Tucker, Brent P.W. Burgess and Steven C. Lilly. We refer to these three officers in 2011 as our named executive officers, or NEOs. Our executive compensation program is designed to encourage our executive officers to think and act like stockholders of the Company. The structure of the NEOs’ compensation programs was designed to encourage and reward the following factors, among others:

| • |  | sourcing and pursuing attractively priced investment opportunities in lower middle market privately-held companies;

| • |  | achievement of the Company’s dividend objectives (which focuses on stability and potential growth);

| • |  | maintaining credit quality, monitoring financial performance and ultimately managing a successful exit of the Company’s investment portfolio; and

| • |  | development of management team and employees.

We completed our initial public offering, or IPO, in February 2007. As our first five years of operation as a publicly traded BDC have represented a period of constant development and growth for us, our Compensation Committee focuses on creating an executive compensation program that will effectively achieve our desired objectives stated above.

In May 2011, we held a stockholder advisory vote on the compensation of our NEOs, commonly referred to as a say-on-pay vote. Our stockholders overwhelmingly approved the compensation of our NEOs, with over 93% of stockholder votes cast in favor of our say-on-pay resolution.

Executive Compensation Policy

The compensation programs of the Company adopted by our Compensation Committee are designed with the goal of providing compensation that is fair, reasonable and competitive and are intended to align the compensation paid to our NEOs with both our short-term and long-term objectives. The key elements of our compensation philosophy include: (i) designing compensation programs that enable us to attract and retain the best talent in the financial industries in which we compete; (ii) aligning executive compensation packages with the Company’s performance; and (iii) using long-term equity awards to align employee and stockholder interests.

As a BDC, we must comply with the requirements of the 1940 Act. The 1940 Act imposes certain limitations on the structure of our compensation programs, including limitations on our ability to issue certain equity-based compensation to our employees and directors. Triangle has received exemptive relief from the SEC that permits the company to grant restricted stock in exchange for or in recognition of services by its executive officers and employees. Pursuant to the Equity Incentive Plan, the Compensation Committee may award shares of restricted stock to plan participants in such amounts and on such terms as the Committee determines in its sole discretion, provided that such awards are consistent with the conditions set forth in the SEC’s exemptive order.

##### Table of Contents

Overview

Our performance-driven compensation policy consists primarily of the following three components:

| • |  | Base salary;

| • |  | Annual cash bonuses; and

| • |  | Long-term compensation pursuant to the Equity Incentive Plan.

Other compensation components may include contributions to our 401(k) and deferred compensation plans, and health, life, and disability insurance premiums paid by the Company.

We designed each NEO’s compensation package to appropriately reward the NEO for his contribution to the Company. Our compensation philosophy has not historically been, and going forward will not be, a mechanical process, and our Compensation Committee will continue to use its judgment and experience, working in conjunction with our chief executive officer and, potentially, an independent compensation consultant, to determine the appropriate mix of compensation for each individual. Cash compensation consisting of base salary and discretionary cash bonuses tied to achievement of performance goals set by the Compensation Committee are intended to incentivize NEOs to remain with us in their roles and work hard to achieve our goals. Stock-based compensation in the form of restricted stock is awarded based on individual performance expectations set by the Compensation Committee.

Establishing Compensation Levels

Role of the Compensation Committee and Management

As set forth in the Compensation Committee Charter, our Compensation Committee’s primary responsibility is to evaluate the compensation of our executive officers and assure that they are compensated effectively and in a manner consistent with our stated compensation objectives. The Compensation Committee also periodically reviews our corporate goals and objectives relevant to executive compensation, our executive compensation structure to ensure that it is designed to achieve the objectives of rewarding the company’s executive officers appropriately for their contributions to corporate growth and profitability and our other goals and objectives. At least annually, the Compensation Committee will evaluate the compensation of our executive officers and determine the amounts and individual elements of total compensation for executive officers consistent with our corporate goals and objectives and will communicate to stockholders the factors and criteria on which the executive officers’ compensation is based, including the relationship of our performance to the executive officers’ compensation. With respect to the compensation of our executive officers other than the chief executive officer, the Committee works with the chief executive officer to conduct these reviews. The Committee will also periodically evaluate the terms and administration of our annual and long-term incentive plans, including equity compensation plans, to ensure that they are structured and administered in a manner consistent with our goals and objectives as to participation in such plans, target annual incentive awards, corporate financial goals, actual awards paid to executive officers and total funds allocated for payment under the compensation plans.

Assessment of Market Data

To assess the competitiveness of our executive compensation levels, we developed a comparative group of both externally and internally managed BDCs and performed comprehensive analyses of competitive performance and compensation levels. In 2011, the internally managed comparative group included the following: Capital Southwest Corporation; Hercules Technology Growth Capital, Inc.; Kohlberg Capital Corporation; Main Street Capital Corporation; MCG Capital Corporation; and Medallion Financial Corp. However, we do not specifically benchmark the compensation of our NEOs against that paid by other companies with publicly traded securities. This is because we believe that our primary competitors in both our business and

111

##### Table of Contents

for recruiting executives are investment banks, private equity firms, mezzanine lenders, hedge funds and other specialty finance companies, including certain specialized commercial banks. Many of these entities do not publicly report the compensation of their executive officers nor do they typically report publicly information on their corporate performance. While various salary surveys from other private sources may become available to us with regard to these private equity firms, we believe that without accurate, publicly disclosed information on these private entities that would serve as benchmarks, it is inappropriate for us to set formal benchmarking procedures.

Our analysis centered around key elements of compensation practices within the BDC industry in general and, more specifically, compensation practices at internally managed BDCs closer in asset size, typical investment size, typical investment type, market capitalization, and general business scope to our Company. Items we reviewed included, but were not necessarily limited to, base compensation, bonus compensation and restricted stock awards. In addition to actual levels of compensation, we also analyzed the approach other BDCs were taking with regard to their compensation practices. Items we reviewed included, but were not necessarily limited to, certain corporate and executive performance measures established to achieve total returns for stockholders and our “efficiency ratio” compared to other BDCs in our comparative group (which is calculated by taking total general and administrative expenses and dividing it by the company’s total revenue).

While each of the BDCs listed above is not comparable in size, scope and operations, the Compensation Committee believes that given the size and uniqueness of our industry, they were the most relevant comparable companies available with disclosed executive compensation data, and they provide a good representation of competitive compensation levels for our executives.

Assessment of Company Performance

In determining annual compensation for our NEOs, our Compensation Committee evaluates the individual performance of our NEOs as well as the Company’s overall operating performance. We believe that the alignment of (i) a company’s business plan, (ii) its stockholders expectations and (iii) its employee compensation is essential to long term business success in the interest of our stockholders and employees. We typically make three to seven year investments in privately held businesses. Our business plan involves taking on investment risk over an extended period of time, and a premium is placed on our ability to maintain stability of net asset values and continuity of earnings to pass through to stockholders in the form of recurring dividends. Our strategy is to generate income and capital gains from our investments in the debt and equity securities of our portfolio companies. This income supports the payment of dividends to our stockholders. Therefore, a key element of our return to stockholders is in the form of current income through the payment of dividends. This recurring payout requires a methodical asset acquisition approach and active monitoring and management of our investment portfolio over time. A substantial part of our employee base is dedicated to the maintenance of asset values and expansion of this recurring revenue to support and grow dividends.

In reviewing and approving the compensation packages for our executive officers and other key employees, our Compensation Committee considers the relative achievement of the Company’s strategic and corporate objectives, executive performance factors and the individual performance of each of our NEOs. For 2011, some of the most significant company-specific performance factors considered by the Compensation Committee include:

| • |  | total investment income;

| • |  | total net investment income;

| • |  | realized and unrealized gains and losses;

| • |  | overall credit performance of the investment portfolio;

| • |  | liquidity;

112

##### Table of Contents

| • |  | operating efficiency performance;

| • |  | growth and diversification of the overall investment portfolio;

| • |  | sustaining and growing dividends and distributions to stockholders; and

| • |  | return on average stockholders’ equity.

Elements of Triangle’s Executive Compensation

In 2011, the compensation program was comprised primarily of the following three elements: (i) base salary, (ii) annual cash bonus and (iii) long-term equity incentive compensation. Although it does not allocate a fixed percentage of the NEO compensation packages to each of these elements, the Compensation Committee does seek to achieve an appropriate balance among these elements to incentivize our NEOs to focus on financial and operating results in the near term and the creation of stockholder value over the long term.

2011 Annual Base Salary

The annual base salary is designed to provide a minimum, fixed level of cash compensation to our NEOs in order to attract and retain experienced executive officers who can drive the achievement of our goals and objectives. The Compensation Committee annually reviews the base salary for each of our executive officers and determines whether or not to adjust it in its sole discretion. Increases to base salary are awarded to recognize levels of responsibilities and related individual performance, and to address changes in the external competitive market for a given position.

In establishing the 2011 base salaries of the NEOs, the Compensation Committee and management considered a number of factors including the seniority of the individual, the functional role of the position, the level of the individual’s responsibility, the ability to replace the individual and the base salary of the individual in 2010. In addition, we considered the base salaries paid to comparably situated executive officers in other BDCs and other competitive market practices. Finally, we used a compensation consultant in order to obtain an objective third party expert’s insight into our NEOs’ base salaries.

Mr. Tucker was paid an annual base salary of $355,000 as of December 31, 2011. Mr. Tucker’s base salary recognizes his overall responsibility for the Company and his continued leadership which has enabled us to achieve our historical operational and financial objectives.

Mr. Burgess was paid an annual base salary of $302,500 as of December 31, 2011. Mr. Burgess’ base salary recognizes his lead role in managing all investment activity of the Company, including marketing, structuring, closing and monitoring portfolio company investments.

Mr. Lilly was paid an annual base salary of $270,000 as of December 31, 2011. Mr. Lilly’s base salary recognizes his lead role in managing all financial aspects of our Company, and his leadership in matters relating to our capital structure, the media and investor relations. Mr. Lilly’s base salary also reflected his service as our Company’s Chief Compliance Officer.

2011 Annual Cash Bonuses

We pay annual cash bonuses to reward corporate and individual achievements for the prior fiscal year. Annual cash bonuses are based on the Compensation Committee’s discretionary assessment of the Company’s and the NEO’s performance, with recommendations from the chief executive officer for NEOs other than himself.

113

##### Table of Contents

On a quarterly basis, the Compensation Committee, together with input from our chief executive officer, approves an accrual for the annual potential cash bonus pool. The determination of the accrual amount is dependent upon the Company’s current financial outlook and executive performance contributing to achieving our corporate objectives, and is subject to the sole discretion of the Compensation Committee.

The Company paid cash bonuses to NEOs in 2012 in recognition of both corporate and individual 2011 performance. In particular, for the year ended December 31, 2011, we achieved the following financial highlights:

| • |  | investments in 63 portfolio companies as of December 31, 2011, as compared to investments in 48 portfolio companies as of December 31, 2010;

| • |  | total investment income of $63.4 million, representing an increase of approximately 76.1% from 2010;

| • |  | net investment income of $40.3 million, representing an increase of approximately 100.2% from 2010;

| • |  | net investment income per share of $2.06, representing an increase of approximately 30.4% from 2010;

| • |  | net unrealized appreciation of investments, net of income taxes, in the amount of $6.4 million and a net realized gain on investments of $11.0 million, for a total net gain on investments of approximately $17.3 million;

| • |  | net increase in net assets resulting from operations per share of $2.90, representing an increase of approximately 45.7% from 2010; and

| • |  | dividends and distributions during 2011 of $1.77 per share as compared to $1.65 per share in 2010.

Mr. Tucker was paid an annual cash bonus of $555,000 for 2011, which is a $237,500 increase from his annual cash bonus for 2010. Mr. Tucker’s cash bonus reflects his overall responsibility for the Company and his continued leadership in 2011, which enabled us to achieve the majority of our operational and financial objectives.

Mr. Burgess was paid an annual cash bonus of $602,500 for 2011, which is a $327,500 increase from his annual cash bonus for 2010. Mr. Burgess’ cash bonus reflects his ability to manage the Company’s investment process, including sourcing new investments, monitoring our portfolio and guiding all of the investments we made during 2011 to a successful closing on terms we believe will be favorable to the Company.

Mr. Lilly was paid an annual cash bonus of $355,000 for 2011, which is a $105,000 increase from his annual cash bonus for 2010. Mr. Lilly’s cash bonus reflects his lead role in managing all financial aspects of our Company, including his leadership in matters relating to our capital structure, the media and investor relations. Mr. Lilly’s cash bonus also reflected his service as our Chief Compliance Officer during 2011.

The Compensation Committee believes that these cash bonus awards are individually appropriate based on the Company’s 2011 performance and each individual’s contribution to the Company throughout 2011 as stated above. Such bonuses comprise a key component of the Company’s overall compensation program.

Long Term Incentive Compensation

General

Our Board of Directors adopted the Equity Incentive Plan in order to provide stock-based awards as incentive compensation to our employees and non-employee directors. Since our IPO, our Compensation Committee has chosen to utilize shares of our restricted stock, rather than stock options or other equity-based incentive compensation, as long term incentive compensation.

114

##### Table of Contents

We use restricted stock awards to (i) attract and retain key employees, (ii) motivate our employees by means of performance-related incentives to achieve long-range performance goals, (iii) enable our employees to participate in our long-term growth and (iv) link our employees’ compensation to the long-term interests of our stockholders. The Compensation Committee has been delegated exclusive authority by our Board of Directors to select the persons to receive stock-based awards. At the time of each award granted to each NEO, the Compensation Committee determines the terms of the award in its sole discretion, including their performance period (or periods) and the performance objectives relating to the award.

The Equity Incentive Plan allows our Board (and Compensation Committee, after delegation of administrative duties) to grant shares of restricted stock to our employees. Each restricted stock award is for a fixed number of shares as set forth in an award agreement between the grantee and us. Award agreements set forth time and/or performance vesting schedules and other appropriate terms and/or restrictions with respect to awards, including rights to dividends and voting rights.

2011 Restricted Stock Awards

Specific performance factors that the Compensation Committee considered in determining the granting of restricted stock in 2011 included individual employee performance objectives such as work ethic, proficiency and overall contribution to the Company during our fiscal year ended December 31, 2010. The amount of restricted stock awarded to each of our executive officers is unrelated to the number of shares we may sell below net asset value.

Mr. Tucker was awarded 32,779 shares of restricted stock in 2011, which is an increase of 1,946 shares of restricted stock from that which was granted to him in 2010. The grant date fair value of the 2011 award was $672,297. This award reflects Mr. Tucker’s leadership during 2010, which enabled us to achieve the majority of our operational and financial objectives. Mr. Tucker’s performance during this time period was vital to our Company’s success.

Mr. Burgess was awarded 28,333 shares of restricted stock in 2011, which is an increase of 1,666 shares of restricted stock from that which was granted to him in 2010. The grant date fair value of the 2011 award was $581,110. This award reflects Mr. Burgess’ leadership in implementing our investment strategy during 2010, including the expansion of our investment team, the deal sourcing of certain portfolio investments and guidance of each investment through our internal investment process from inception to closing.

Mr. Lilly was awarded 22,779 shares of restricted stock in 2011, which is an increase of 1,946 shares of restricted stock from that which was granted to him in 2010. The grant date fair value of the 2011 award was $467,197. This award reflects Mr. Lilly’s role in managing all financial aspects of our Company, and his leadership in matters relating to our capital structure, the media and investor relations. Mr. Lilly’s restricted stock award also reflects his continued service as our Chief Compliance Officer.

Options

Since our IPO, our Compensation Committee has not utilized options to purchase our common stock as a form of compensation to our NEOs and other employees. As such, we did not grant any stock options to our employees in 2011.

Our Compensation Committee may, however, in its sole discretion (upon delegation by the Board) grant our employees options to purchase our common stock (including incentive stock options and non-qualified stock options). We expect that, if granted, options will represent a fixed number of shares of our common stock, will have an exercise, or strike, price equal to the fair market value of our common stock on the date of such grant, and will be exercisable, or “vested,” at some later time after grant. Upon any stock option grant, its exercise price will not be changed absent specific SEC approval that we may do so. The “fair market value” will be defined as

115

##### Table of Contents

either (i) the closing sales price of the our common stock on the NYSE, or any other such exchange on which the shares are traded, on such date, (ii) in the absence of reported sales on such date, the closing sales price on the immediately preceding date on which sales were reported or (iii) in the event there is no public market for the shares on such date, the fair market value as determined, in good faith, by our Board in its sole discretion (which will in no event will be less than the net asset value of such shares of common stock on such date), and for purposes of a sale of a share of common stock as of any date, the actual sales price on that date. Some stock options granted by our Compensation Committee may vest simply by the holder remaining with the Company for a period of time, and some may vest based on meeting certain performance goals. We anticipate that our options, if granted in the future, will be valued for financial reporting purposes using the Black Scholes valuation method, and charges to earnings will be taken over the relevant service period pursuant to FASB ASC Topic 718.

Other Compensation Matters

401(k) Plan

We maintain a 401(k) plan in which all full-time employees who are at least 21 years of age and have 90 days of service are eligible to participate and receive certain employer contributions. Eligible employees have the opportunity to contribute their compensation on a pretax salary basis into the 401(k) plan up to $16,500 for the plan year, and to direct the investment of these contributions. Plan participants who reach the age of 50 prior to or during the plan year are eligible to defer up to an additional $5,500 for the plan year.

Deferred Compensation Plan

The Compensation Committee has adopted a nonqualified deferred compensation plan covering the Company’s executive officers and key employees. Any compensation deferred and the Company’s additional contributions, if any, will earn a return based on the returns on certain investments designated by the Compensation Committee. Participants are 100% vested in amounts deferred under the plan and the earnings thereon, and such amounts vest over a four year period.

Tax and Accounting Considerations

Section 162(m) of the Code limits our deduction for U.S. federal income tax purposes to not more than $1 million of compensation paid to certain executive officers in a calendar year. Compensation above $1 million may be deducted if it is “performance-based compensation” as defined in the Code and the Treasury Regulations thereunder. Our Compensation Committee has not established a policy for determining which forms of incentive compensation awarded to our executive officers should be designated to qualify as “performance-based compensation” for U.S. federal income tax purposes. To maintain flexibility in compensating our executive officers in a manner designed to promote our objectives, the Compensation Committee has not adopted a policy that requires all compensation to be deductible. However, the Compensation Committee evaluates the effects of the compensation limits of Section 162(m) of the Code on all compensation it proposes to grant, and the Compensation Committee intends to provide all executive compensation in a manner consistent with our best interests and those of our stockholders. In 2011, none of our executive officers received compensation that would exceed the $1 million limit on deductibility under Section 162(m) of the Code.

In awarding restricted stock awards for performance in 2011, we accounted for share-based awards under the provisions of FASB ASC Topic 718. FASB ASC Topic 718 establishes accounting for stock-based awards exchanged for goods or services. Accordingly, stock-based compensation cost is measured at grant date, based on the fair value of the awards, and is recognized as an expense ratably over the requisite service period. Accounting rules also require us to record cash compensation as an expense at the time the obligation is incurred.

Conclusion

Our compensation policies are designed to fairly compensate, retain and motivate our NEOs. The retention and motivation of our NEOs should enable us to grow strategically and position ourselves competitively in the market in which we operate.

Compensation Mix

As discussed in more detail in the section entitled “Compensation Discussion and Analysis”, in 2011, the Company’s compensation program was comprised primarily of the following three elements: (i) base salary, (ii) annual cash bonuses and (iii) long-term equity compensation. Although it does not allocate a fixed percentage of the NEO compensation packages to each of these elements, the Compensation Committee does seek to achieve an appropriate balance among these elements to incentivize our NEOs to focus on financial and operating results in the near term and the creation of stockholder value over the long term.

In 2011, salaries comprised 18.8%, 17.4% and 20.8% of total compensation for Messrs. Tucker, Burgess and Lilly, respectively. The annual base salary of each NEO is to be determined annually at the discretion of the Compensation Committee. Moreover, in 2011, annual cash bonuses comprised 30.3%, 35.5% and 27.9% of total compensation for Messrs. Tucker, Burgess and Lilly, respectively.

Equity Incentive Plan

The restricted stock awards granted to our NEOs during 2011 that appear in the tables above and below were granted pursuant to the Equity Incentive Plan. On March 18, 2008 we received an exemptive order from the SEC authorizing such issuance of restricted stock to our employees and non-employee directors pursuant to the terms of the Equity Incentive Plan and as otherwise set forth in the exemptive order. In 2008, our Board approved, and the stockholders voted to approve, the Equity Incentive Plan. The Equity Incentive Plan initially reserved up to 900,000 shares of our common stock for issuance and currently authorizes up to 2,400,000 shares of our common stock for issuance. Currently there are 1,709,938 shares available for issuance under the Equity Incentive Plan.

Participants in the Equity Incentive Plan who are employees may receive awards of options to purchase shares of common stock or grants of restricted stock, as determined by the Board. The basis of such participation is to provide incentives to our employees in order to attract and retain the services of qualified professionals.

The Equity Incentive Plan includes provisions allowing the issuance of restricted stock to all key employees consistent with such terms and conditions as the Board shall deem appropriate, subject to the limitations set forth in the plan. Restricted stock refers to an award of stock that is subject to forfeiture restrictions and may not be transferred until such restrictions have lapsed. With respect to awards issued to our employees, the Board will determine the time or times at which such shares of restricted stock will become exercisable and the terms on which such shares will remain exercisable. Shares granted pursuant to a restricted stock award will not be transferable until such shares have vested in accordance with the terms of the award agreement, unless the transfer is by will or by the laws of descent and distribution. The Equity Incentive Plan also allows us to issue options to our key employees in the future should our Board and Compensation Committee choose to do so.

Our Board of Directors has delegated administration of the Equity Incentive Plan to our Compensation Committee, currently comprised solely of three (3) independent directors who are independent pursuant to the listing requirements of the NYSE. Our Board may abolish the Compensation Committee at any time and revest in our Board the administration of the Equity Incentive Plan. Our Board administers the Equity Incentive Plan in a manner that is consistent with the applicable requirements of the NYSE and the exemptive order.

On February 4, 2011, the Board of Directors, upon recommendation of our Compensation Committee, approved grants of restricted stock awards to the Company’s executive officers as set forth above. All of these restricted shares of stock were valued at $20.51, the closing price of our common stock on the NYSE on February 4, 2011, the grant date. The restricted share awards granted to the executive officers vest ratably over four years from this grant date.

None of these shares of restricted stock may be sold, assigned, transferred, pledged, hypothecated or otherwise encumbered or disposed of prior to the their vesting date, and, except as otherwise determined by our Board or Compensation Committee at or after the grant of each executive officer’s award of restricted stock, any

118

##### Table of Contents

of the shares which have not fully vested will be forfeited, and all rights of the executive officer to such shares shall terminate, without further obligation on the part of Triangle, unless the executive officer remains employed with us for the entire vesting period relating to the restricted stock.

In addition, in accordance with the Equity Incentive Plan and each individual award agreement, any share of the Company’s stock distributed with respect to the restricted stock reflected in the table above is subject to the same ratable vesting restrictions, terms and conditions as the restricted stock awarded to each executive officer.

2011 Outstanding Equity Awards at Fiscal Year End

(2) | Represents amounts earned for 2011 and contributed to the Executive Deferred Compensation Plan in 2012. All of the amounts shown in this column are also reported in the “All Other Compensation” column of the Summary Compensation Table for 2011.

During the first quarter of 2012, the Compensation Committee of the Board of Directors approved the Company’s adoption of a non-qualified deferred compensation plan for certain senior executive officers and key employees, including the NEOs (the “Executive Deferred Compensation Plan”). The Executive Deferred Compensation Plan is an unfunded plan maintained for the purpose of providing participating executives with additional deferred compensation. Pursuant to the Executive Deferred Compensation Plan, the Company will contribute certain amounts for the benefit of the participating executives from time to time. In the future, the Company may allow participating executives to elect to contribute on a pre-tax basis up to 50% of their base salary and up to 100% of their cash bonus. The Company may elect to match a portion of such contributions. Contributions to the Executive Deferred Compensation Plan will earn a fixed rate of return. This rate of return is

120

##### Table of Contents

currently determined to equal the rate of return of a hypothetical investment in a mutual fund providing a return equal to the S&P Total Return Index. Participants will be 100% vested in any elective deferrals, and will vest in any Company contributions ratably over four years from the date of the relevant contribution. Distributions to participants are generally payable upon termination of employment.

Potential Payments upon Termination or Change in Control

This section describes and quantifies the estimated compensation payments and benefits that would be paid to our NEOs upon the occurrence of each of the following triggering events:

| • |  | termination upon death or disability (as defined in the Equity Incentive Plan);

| • |  | occurrence of a change in control in the Company (as defined in the Equity Incentive Plan).

Effective February 2009, as a result of the determination by our Compensation Committee that it would be in the best interests of the Company and our stockholders for the Company to operate without employment agreements, none of our employees is party to an employment agreement with the Company. The information below describes those limited instances in which our NEOs would be entitled to payments or other benefits following a termination of employment and/or upon a change in control of Triangle without employment agreements. Our NEOs are “at will” employees and, except as otherwise described below, they are only entitled to payment of accrued salary and vacation time, on the same terms as provided to our other employees, upon any resignation, retirement or termination of employment, with or without cause. Except as otherwise noted below, the calculations below do not include any estimated payments for those benefits that we generally make available on the same terms to our full-time, non-executive employees.

The estimated payments below are calculated based on compensation arrangements in effect as of December 31, 2011 and assume that the triggering event occurred on such date. The estimated benefit amounts are based on a common stock price of $19.12, which was the closing price per share of our common stock on the NYSE on December 31, 2011 and these amounts could be paid lump sum by us should the triggering event occur below. Our estimates of potential benefits are further based on the additional assumptions specifically set forth in the table below. Although these calculations are intended to provide reasonable estimates of potential compensation benefits, the estimated benefit amounts may differ from the actual amount that any individual would receive upon termination or the costs to Triangle associated with continuing certain benefits following termination of employment.

CERTAIN RELATIONSHIPS AND TRANSACTIONS

The 1940 Act prohibits certain transactions between us, Triangle SBIC, Triangle SBIC II, as well as our and their affiliates, without first obtaining an exemptive order from the SEC. We and Triangle SBIC initially filed a joint exemptive application with the SEC in 2007 and then received exemptive relief to our amended exemptive application in 2008. In 2010, we jointly filed with Triangle SBIC and Triangle SBIC II another amendment to the

121

##### Table of Contents

exemptive application requesting relief under various sections of the 1940 Act to permit us, as the BDC parent, Triangle SBIC, as a BDC and our SBIC subsidiary, and Triangle SBIC II, as our SBIC subsidiary, to operate effectively as one company for 1940 Act regulatory purposes. Specifically, the application requested relief for us, Triangle SBIC and Triangle SBIC II to (a) engage in certain transactions with each other, (b) invest in securities in which the other is an investor and engage in transactions with portfolio companies that would not otherwise be prohibited if we, Triangle SBIC and Triangle SBIC II were one company, (c) be subject to modified consolidated asset coverage requirements for senior securities issued by Triangle Capital Corporation along with Triangle SBIC and Triangle SBIC II as SBIC subsidiaries and (d) allow Triangle SBIC and Triangle SBIC II to file reports under the Exchange Act on a consolidated basis with Triangle Capital Corporation, the parent BDC. On October 22, 2010, the SEC issued an exemptive relief order approving our requests.

In addition, under current SEC rules and regulations, BDCs may not grant options or restricted stock to directors who are not officers or employees of the BDC. Similarly, under the 1940 Act, BDCs cannot issue stock for services to their executive officers and employees other than options, warrants and rights to acquire capital stock. In March 2008, we received an exemptive relief order from the SEC that (a) permits us to grant restricted stock to our independent directors as a part of their compensation for service on our Board and (b) permits us to grant restricted stock in exchange for or in recognition of services by our executive officers and employees.

SALES OF COMMON STOCK BELOW NET ASSET VALUE

On May 2, 2012, our stockholders approved our ability to sell or otherwise issue an unlimited number of shares of our common stock at any level of discount from NAV per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. In order to sell shares pursuant to this authorization a majority of our directors who have no financial interest in the sale or issuance and a majority of our independent directors must (a) find that the sale or issuance is in our best interests and in the best interests of our stockholders, and (b) in consultation with any underwriter or underwriters of the offering, make a good faith determination as of a time either immediately prior to the first solicitation by us or on our behalf of firm commitments to purchase such shares, or immediately prior to the issuance of such shares, that the price at which such shares are to be sold or otherwise issued is not less than a price which closely approximates the market value of such shares, less any distributing commission or discount. Any offering of common stock below NAV per share will be designed to raise capital for investment in accordance with our investment objective.

In making a determination that an offering below NAV per share is in our and our stockholders’ best interests, our Board of Directors would consider a variety of factors including:

| • |  | The effect that an offering below NAV per share would have on our stockholders, including the potential dilution they would experience as a result of the offering;

| • |  | The amount per share by which the offering price per share and the net proceeds per share are less than the most recently determined NAV per share;

| • |  | The relationship of recent market prices of par common stock to NAV per share and the potential impact of the offering on the market price per share of our common stock;

| • |  | Whether the estimated offering price would closely approximate the market value of our shares;

| • |  | The potential market impact of being able to raise capital during the current financial market difficulties;

| • |  | the nature of any new investors anticipated to acquire shares in the offering;

| • |  | The anticipated rate of return on and quality, type and availability of investments; and

| • |  | The leverage available to us.

We will not sell or otherwise issue shares under a prospectus supplement to the post-effective amendment to the registration statement of which this prospectus forms a part (the “current amendment”) if the cumulative dilution to the Company’s NAV per share from offerings under the current amendment exceeds 15%. This would be measured separately for each offering pursuant to the current amendment by calculating the percentage dilution or accretion to aggregate NAV from that offering and then summing the percentage from each offering. For example, if our most recently determined NAV at the time of the first offering is $15.00 and we have 30 million shares outstanding, a sale of 6 million shares at net proceeds to us of $7.50 per share (a 50% discount) would produce dilution of 8.33%. If we subsequently determined that our NAV per share increased to $15.75 on the then 36 million shares outstanding and then made an additional offering, we could, for example, sell approximately an additional 7.2 million shares at net proceeds to us of $9.45 per share, which would produce dilution of 6.67%, before we would reach the aggregate 15% limit. If we file a new post-effective amendment, the threshold would reset.

Sales or other issuances by us of our common stock at a discount from NAV pose potential risks for our existing stockholders whether or not they participate in the offering, as well as for new investors who participate in the offering.

124

##### Table of Contents

The following three headings and accompanying tables will explain and provide hypothetical examples on the impact of an offering at a price less than NAV per share on three different set of investors:

| • |  | existing stockholders who do not purchase any shares in the offering;

| • |  | existing stockholders who purchase a relative small amount of shares in the offering or a relatively large amount of shares in the offering;

| • |  | new investors who become stockholders by purchasing shares in the offering.

Impact On Existing Stockholders Who Do Not Participate in the Offering

Our existing stockholders who do not participate in an offering below NAV per share or who do not buy additional shares in the secondary market at the same or lower price we obtain in the offering (after expenses and commissions) face the greatest potential risks. These stockholders will experience an immediate decrease (often called dilution) in the NAV of the shares they hold and their NAV per share. These stockholders will also experience a disproportionately greater decrease in their participation in our earnings and assets and their voting power than the increase we will experience in our assets, potential earning power and voting interests due to the offering. These stockholders may also experience a decline in the market price of their shares, which often reflects to some degree announced or potential increases and decreases in NAV per share. This decrease could be more pronounced as the size of the offering and level of discounts increases.

The following table illustrates the level of net asset value dilution that would be experienced by a nonparticipating stockholder in three different hypothetical offerings of different sizes and levels of discount from net asset value per share, although it is not possible to predict the level of market price decline that may occur. Actual sales prices and discounts may differ from the presentation below.

125

##### Table of Contents

The examples assume that Company XYZ has 1,000,000 shares of common stock outstanding, $15,000,000 in total assets and $5,000,000 in total liabilities. The current net asset value and net asset value per share are thus $10,000,000 and $10.00. The table illustrates the dilutive effect on nonparticipating Stockholder A of (1) an offering of 50,000 shares (5% of the outstanding shares) at $9.50 per share after offering expenses and commission (a 5% discount from net asset value), (2) an offering of 100,000 shares (10% of the outstanding shares) at $9.00 per share after offering expenses and commissions (a 10% discount from net asset value) and (3) an offering of 200,000 shares (20% of the outstanding shares) at $8.00 per share after offering expenses and commissions (a 20% discount from net asset value). The acronym “NAV” stands for “net asset value.”

Impact On Existing Stockholders Who Do Participate in the Offering

Our existing stockholders who participate in an offering below NAV per share or who buy additional shares in the secondary market at the same or lower price as we obtain in the offering (after expenses and commissions) will experience the same types of NAV dilution as the nonparticipating stockholders, albeit at a lower level, to the extent they purchase less than the same percentage of the discounted offering as their interest in our shares immediately prior to the offering. The level of NAV dilution will decrease as the number of shares such stockholders purchase increases. Existing stockholders who buy more than such percentage will experience NAV dilution but will, in contrast to existing stockholders who purchase less than their proportionate share of the offering, experience an increase (often called accretion) in NAV per share over their investment per share and will also experience a disproportionately greater increase in their participation in our earnings and assets and their voting power than our increase in assets, potential earning power and voting interests due to the offering. The level of accretion will increase as the excess number of shares such stockholder purchases increases. Even a stockholder who overparticipates will, however, be subject to the risk that we may make additional discounted offerings in which such stockholder does not participate, in which case such a stockholder will experience NAV dilution as described above in such subsequent offerings. These stockholders may also experience a decline in the market price of their shares, which often reflects to some degree announced or potential increases and decreases in NAV per share. This decrease could be more pronounced as the size of the offering and the level of discounts increases.

127

##### Table of Contents

The following table illustrates the level of dilution and accretion in the hypothetical 20% discount offering from the prior table (Example 3) for a stockholder that acquires shares equal to (1) 50% of its proportionate share of the offering (i.e., 1,000 shares, which is 0.5% of an offering of 200,000 shares) rather than its 1.0% proportionate share and (2) 150% of such percentage (i.e. 3,000 shares, which is 1.5% of an offering of 200,000 shares rather than its 1.0% proportionate share). The prospectus supplement pursuant to which any discounted offering is made will include a table for these examples based on the actual number of shares in such offering and the actual discount from the most recently determined NAV per share. It is not possible to predict the level of market price decline that may occur. Actual sales prices and discounts may differ from the presentation below.

Impact On New Investors

Investors who are not currently stockholders and who participate in an offering below NAV but whose investment per share is greater than the resulting NAV per share due to selling compensation and expenses paid by the issuer will experience an immediate decrease, albeit small, in the NAV of their shares and their NAV per share compared to the price they pay for their shares. Investors who are not currently stockholders and who participate in an offering below NAV per share and whose investment per share is also less than the resulting NAV per share due to selling compensation and expenses paid by the issuer being significantly less than the discount per share will experience an immediate increase in the NAV of their shares and their NAV per share

compared to the price they pay for their shares. These investors will experience a disproportionately greater participation in our earnings and assets and their voting power than our increase in assets, potential earning power and voting interests. These investors will, however, be subject to the risk that we may make additional discounted offerings in which such new stockholder does not participate, in which case such new stockholder will experience dilution as described above in such subsequent offerings. These investors may also experience a decline in the market price of their shares, which often reflects to some degree announced or potential increases and decreases in NAV per share. This decrease could be more pronounced as the size of the offering and level of discounts increases.

The following table illustrates the level of dilution or accretion for new investors that would be experienced by a new investor in the same hypothetical 5%, 10% and 20% discounted offerings as described in the first table above. The illustration is for a new investor who purchases the same percentage (1.0%) of the shares in the offering as Stockholder A in the prior examples held immediately prior to the offering. The prospectus supplement pursuant to which any discounted offering is made will include a table for these examples based on the actual number of shares in such offering and the actual discount from the most recently determined NAV per share. It is not possible to predict the level of market price decline that may occur. Actual sales prices and discounts may differ from the presentation below.

DIVIDEND REINVESTMENT PLAN

We have adopted a dividend reinvestment plan that provides for reinvestment of our distributions on behalf of our common stockholders, unless a common stockholder elects to receive cash as provided below. As a result, if our Board of Directors authorizes, and we declare, a cash dividend, then our common stockholders who have not “opted out” of our dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of our common stock, rather than receiving the cash dividends.

No action will be required on the part of a registered common stockholder to have his or her cash dividend reinvested in shares of our common stock. A registered common stockholder may elect to receive an entire dividend in cash by notifying Computershare Shareowner Services, LLC, the “Plan Administrator” and our transfer agent and registrar, in writing so that such notice is received by the Plan Administrator no later than the record date for dividends to common stockholders. The Plan Administrator will set up an account for shares acquired through the plan for each common stockholder who has not elected to receive dividends in cash and hold such shares in non-certificated form. Upon request by a common stockholder participating in the plan, received in writing not less than 10 days prior to the record date, the Plan Administrator will, instead of crediting shares to the participant’s account, issue a certificate registered in the participant’s name for the number of whole shares of our common stock and a check for any fractional share. Those common stockholders whose shares are held by a broker or other financial intermediary may receive dividends in cash by notifying their broker or other financial intermediary of their election.

We intend to use primarily newly issued shares to implement the plan, so long as our shares are trading at or above net asset value. If our shares are trading below net asset value, we intend to purchase shares in the open market in connection with our implementation of the plan. If we use newly issued shares to implement the plan, the number of shares to be issued to a common stockholder is determined by dividing the total dollar amount of the dividend payable to such common stockholder by the market price per share of our common stock at the close of regular trading on the New York Stock Exchange, or the NYSE, on the dividend payment date. Market price per share on that date will be the closing price for such shares on the NYSE or, if no sale is reported for such day, at the average of their reported bid and asked prices. If we purchase shares in the open market to implement the plan, the number of shares to be issued to a common stockholder is determined by dividing the total dollar amount of the dividend payable to such common stockholder by the average price per share for all shares purchased by the Plan Administrator in the open market in connection with the dividend. The number of shares of our common stock to be outstanding after giving effect to payment of the dividend cannot be established until the value per share at which additional shares will be issued has been determined and elections of our common stockholders have been tabulated.

There will be no brokerage charges or other charges to common stockholders who participate in the plan. However, certain brokerage firms may charge brokerage charges or other charges to their customers. We will pay the Plan Administrator’s fees under the plan. If a participant elects by written notice to the Plan Administrator to have the Plan Administrator sell part or all of the shares held by the Plan Administrator in the participant’s account and remit the proceeds to the participant, the Plan Administrator is authorized to deduct a $15.00 transaction fee plus a $0.10 per share brokerage commissions from the proceeds.

Common stockholders who receive dividends in the form of stock generally are subject to the same federal, state and local tax consequences as are common stockholders who elect to receive their dividends in cash. A common stockholder’s basis for determining gain or loss upon the sale of stock received in a dividend from us will be equal to the total dollar amount of the dividend payable to the common stockholder. Any stock received in a dividend will have a holding period for tax purposes commencing on the day following the day on which the shares are credited to the U.S. common stockholder’s account.

Participants may terminate their accounts under the plan by notifying the Plan Administrator via its website at https://www.bnymellon.com/shareowner/equityaccess, by filling out the transaction request form located at the bottom of their statement and sending it to the Plan Administrator at Computershare Shareowner Services LLC, P.O. Box 358035, Pittsburgh, Pennsylvania 15252-8015, or by calling the Plan Administrator at (866) 228-7201.

We may terminate the plan upon notice in writing mailed to each participant at least 30 days prior to any record date for the payment of any dividend by us. All correspondence concerning the plan should be directed to the Plan Administrator by mail at Computershare Shareowner Services LLC, P.O. Box 358035, Pittsburgh, Pennsylvania 15252-8015.

DESCRIPTION OF OUR CAPITAL STOCK

The following description is based on relevant portions of the Maryland General Corporation Law and on our charter and bylaws. This summary may not contain all of the information that is important to you, and we refer you to the Maryland General Corporation Law and our charter and bylaws for a more detailed description of the provisions summarized below.

Capital Stock

Our authorized capital stock consists of 150,000,000 shares of common stock, par value $0.001 per share, of which 27,263,151 shares were outstanding as of March 31, 2012. Under our charter, our Board of Directors is authorized to classify and reclassify any unissued shares of stock into other classes or series of stock, and to cause the issuance of such shares, without obtaining stockholder approval. In addition, as permitted by the Maryland General Corporation Law, but subject to the 1940 Act, our charter provides that the Board of Directors, without any action by our stockholders, may amend the charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series that we have authority to issue. Under Maryland law, our stockholders generally are not personally liable for our debts or obligations.

Common Stock

All shares of our common stock have equal rights as to earnings, assets, distribution and voting privileges, except as described below, and, when they are issued, will be duly authorized, validly issued, fully paid and nonassessable. Distributions may be paid to the holders of our common stock if, as and when authorized by our Board of Directors and declared by us out of assets legally available therefor. Shares of our common stock have no conversion, exchange, preemptive or redemption rights. In the event of a liquidation, dissolution or winding up of our company, each share of our common stock would be entitled to share ratably in all of our assets that are legally available for distribution after we pay all debts and other liabilities and subject to any preferential rights of holders of our preferred stock, if any preferred stock is outstanding at such time. Each share of our common stock is entitled to one vote on all matters submitted to a vote of stockholders, including the election of directors. Except as provided with respect to any other class or series of stock, the holders of our common stock will possess exclusive voting power. There is no cumulative voting in the election of directors, which means that holders of a majority of the outstanding shares of common stock will elect all of our directors, and holders of less than a majority of such shares will be unable to elect any director.

SBA Leverage

Debentures issued by our SBIC subsidiaries and guaranteed by the SBA generally have a maturity of ten years, require semi-annual payments of interest, do not require any principal payments prior to maturity, and, historically, were subject to certain prepayment penalties. Those prepayment penalties no longer apply as of September 2006. As of March 31, 2012, the maximum statutory limit on the dollar amount of outstanding SBA-guaranteed debentures that may be issued by a single SBIC was $150.0 million and $225.0 million for a group of SBICs under common control. As of March 31, 2012, Triangle SBIC has issued $139.6 million of SBA guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of March 31, 2012, Triangle SBIC II has issued $75.0 million in face amount of SBA guaranteed debentures. The weighted average interest rate for all SBA guaranteed debentures as of March 31, 2012, was 4.76%.

Limitation on Liability of Directors and Officers; Indemnification and Advance of Expenses

Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services or (b) active and deliberate dishonesty established by a final judgment as being material to the cause of action. Our charter contains such a provision that eliminates directors’ and officers’ liability to the maximum extent permitted by Maryland law, subject to the requirements of the 1940 Act.

Our charter authorizes us, to the maximum extent permitted by Maryland law and subject to the requirements of the 1940 Act, to indemnify any present or former director or officer or any individual who, while a director or officer and at our request, serves or has served another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee, from and against any claim or liability to which such person may become subject or which such person may incur by reason of his or her service in any such capacity, except with respect to any matter as to which he or she is finally adjudicated in any proceeding not to have acted in good faith in the reasonable belief that his or her action was in our best interest.

Our bylaws obligate us, to the maximum extent permitted by Maryland law and subject to the requirements of the 1940 Act, to indemnify any present or former director or officer or any individual who, while a director or officer and at our request, serves or has served another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee and who is made, or threatened to be made, a party to the proceeding by reason of his or her service in any such capacity from and against any claim or liability to which that person may become subject or which that person may incur by reason of his or her service in any such capacity. Our bylaws also require us, to the maximum extent permitted by Maryland law, without requiring a preliminary determination of the ultimate entitlement to indemnification, to pay or reimburse reasonable expenses incurred by any such indemnified person in advance of the final disposition of a proceeding.

Maryland law requires a corporation (unless its charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful in the defense of any proceeding to which he or she is made, or threatened to be made, a party by reason of his or her service in that capacity. Maryland law permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made, or threatened to be made, a party by reason of their service in those or other capacities unless it is established that (a) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that a personal benefit was improperly received, unless in either case a court orders indemnification,

132

##### Table of Contents

and then only for expenses. In addition, Maryland law permits a corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of (a) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (b) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

We have purchased directors’ and officers’ insurance policies covering our directors and officers and us for any acts and omissions committed, attempted or allegedly committed by any director or officer during the policy period. The policy is subject to customary exclusions.

Provisions of The Maryland General Corporation Law and Charter And Bylaws

The Maryland General Corporation Law and our charter and bylaws contain provisions that could make it more difficult for a potential acquiror to acquire us by means of a tender offer, proxy contest or otherwise. These provisions are expected to discourage certain coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us to negotiate first with our Board of Directors. We believe that the benefits of these provisions outweigh the potential disadvantages of discouraging any such acquisition proposals because, among other things, the negotiation of such proposals may improve their terms.

Director Terms; Election of Directors

Our charter provides that the term of each director is one year unless and until the Board of Directors, acting by authority provided under Section 3-802 of the Maryland General Corporation Law, establishes staggered terms in the manner provided in Section 3-803 of the Maryland General Corporation Law. Our bylaws currently provide that directors are elected by a plurality of the votes cast in the election of directors. Pursuant to our charter and bylaws, our Board of Directors may amend the bylaws to alter the vote required to elect directors.

Number of Directors; Vacancies; Removal

Our charter provides that the number of directors will be set only by the Board of Directors in accordance with our bylaws. Our bylaws provide that a majority of our entire Board of Directors may at any time increase or decrease the number of directors. However, unless the bylaws are amended, the number of directors may never be less than one nor more than 12. We have elected to be subject to the provision of Subtitle 8 of Title 3 of the Maryland General Corporation Law regarding the filling of vacancies on the Board of Directors. Accordingly, except as may be provided by the Board of Directors in setting the terms of any class or series of preferred stock, any and all vacancies on the Board of Directors may be filled only by the affirmative vote of a majority of the remaining directors in office, even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy shall serve for the remainder of the full term of the directorship in which the vacancy occurred and until a successor is elected and qualifies, subject to any applicable requirements of the 1940 Act. Our charter provides that a director may be removed only for cause, as defined in the charter, and then only by the affirmative vote of at least two-thirds of the votes entitled to be cast generally in the election of directors.

Action by Stockholders

Under the Maryland General Corporation Law, stockholder action may be taken only at an annual or special meeting of stockholders or by unanimous consent in lieu of a meeting (unless the charter provides for stockholder action by less than unanimous written consent, which our charter permits only as set forth in our bylaws or in the terms of any class or series of preferred stock). These provisions, combined with the requirements of our bylaws regarding the calling of a stockholder-requested special meeting of stockholders discussed below, may have the effect of delaying consideration of a stockholder proposal until the next annual meeting.

Advance Notice Provisions for Stockholder Nominations and Stockholder Proposals

Our bylaws provide that with respect to an annual meeting of stockholders, nominations of individuals for election to the Board of Directors and the proposal of other business to be considered by stockholders may be made only (1) pursuant to our notice of the meeting, (2) by or at the direction of the Board of Directors or (3) by a stockholder who is a stockholder of record both at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated or on any such other business and who has complied with the advance notice procedures of the bylaws. With respect to special meetings of stockholders, only the business specified in our notice of the meeting may be brought before the meeting. Nominations of individuals for election to the Board of Directors at a special meeting may be made only (1) by or at the direction of the Board of Directors or (2) provided that the meeting has been called in accordance with our bylaws for the purpose of electing directors, by a stockholder who is a stockholder of record both at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting in the election of each individual so nominated and who has complied with the advance notice provisions of the bylaws.

The purpose of requiring stockholders to give us advance notice of nominations and other business is to afford our Board of Directors a meaningful opportunity to consider the qualifications of the proposed nominees and the advisability of any other proposed business and, to the extent deemed necessary or desirable by our Board of Directors, to inform stockholders and make recommendations about such qualifications or business, as well as to provide a more orderly procedure for conducting meetings of stockholders. Although our bylaws do not give our Board of Directors any power to disapprove stockholder nominations for the election of directors or proposals recommending certain action, they may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if proper procedures are not followed and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal without regard to whether consideration of such nominees or proposals might be harmful or beneficial to us and our stockholders.

Calling of Special Meeting of Stockholders

Our bylaws provide that special meetings of stockholders may be called by our Board of Directors and certain of our officers. Additionally, our bylaws provide that, subject to the satisfaction of certain procedural and informational requirements by the stockholders requesting the meeting, a special meeting of stockholders shall be called by our secretary to act upon any matter that may properly be considered at a meeting of stockholders upon the written request of stockholders entitled to cast not less than a majority of all of the votes entitled to be cast on such matter at such meeting.

Approval of Extraordinary Corporate Action; Amendment of Charter and Bylaws

Under Maryland law, a Maryland corporation generally cannot dissolve, amend its charter, merge, sell all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business, unless approved by the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter. However, a Maryland corporation may provide in its charter for approval of these matters by a lesser percentage, but not less than a majority of all of the votes entitled to be cast on the matter. Our charter generally provides for approval of amendments to our charter and extraordinary transactions by the stockholders entitled to cast at least a majority of the votes entitled to be cast on the matter. Our charter also provides that certain amendments and any proposal for our conversion, whether by merger or otherwise, from a closed-end company to an open-end company or any proposal for our liquidation or dissolution requires the approval of the stockholders entitled to cast at least 75.0% of the votes entitled to be cast on such matter. However, if such amendment or proposal is approved by at least 75.0% of our continuing directors (in addition to approval by our Board of Directors), such amendment or proposal may be approved by the stockholders entitled to cast a majority of the votes entitled to be cast on such a matter. The “continuing

134

##### Table of Contents

directors” are defined in our charter as our current directors, as well as those directors whose nomination for election by the stockholders or whose election by the directors to fill vacancies is approved by a majority of the continuing directors then on the Board of Directors.

Our charter and bylaws provide that the Board of Directors will have the exclusive power to make, alter, amend or repeal any provision of our bylaws.

No Appraisal Rights

Except with respect to appraisal rights arising in connection with the Maryland Control Share Acquisition Act, or the Control Share Act, discussed below, as permitted by the Maryland General Corporation Law, our charter provides that stockholders will not be entitled to exercise appraisal rights, unless the Board of Directors, upon the affirmative vote of a majority of the Board of Directors, shall determine that such rights apply, with respect to all or any class or series of stock, to one or more transactions occurring after the date of determination in connection with which holders of such shares would otherwise be entitled to exercise such rights.

Control Share Acquisitions

The Control Share Act provides that control shares of a Maryland corporation acquired in a control share acquisition have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter. Shares owned by the acquiror, by officers or by employees who are directors of the corporation are excluded from shares entitled to vote on the matter. Control shares are voting shares of stock which, if aggregated with all other shares of stock owned by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power:

| • |  | one-tenth or more but less than one-third;

| • |  | one-third or more but less than a majority; or

| • |  | a majority or more of all voting power.

The requisite stockholder approval must be obtained each time an acquiror crosses one of the thresholds of voting power set forth above. Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A control share acquisition means the acquisition of issued and outstanding control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition may compel the board of directors of the corporation to call a special meeting of stockholders to be held within 50 days of demand to consider the voting rights of the shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the meeting. If no request for a meeting is made, the corporation may itself present the question at any stockholders meeting.

If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then the corporation may repurchase for fair value any or all of the control shares, except those for which voting rights have previously been approved. The right of the corporation to repurchase control shares is subject to certain conditions and limitations. Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquiror or of any meeting of stockholders at which the voting rights of the shares are considered and not approved. If voting rights for control shares are approved at a stockholders meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition.

The Control Share Act does not apply (a) to shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction or (b) to acquisitions approved or exempted by the charter or bylaws of the corporation. Our bylaws contain a provision exempting from the Control Share Act any and all acquisitions by any person of our shares of stock. There can be no assurance that such provision will not be otherwise amended or eliminated at any time in the future. However, we will amend our bylaws to be subject to the Control Share Act only if our Board of Directors determines that it would be in our best interests and if the staff of the SEC does not object to our determination that our being subject to the Control Share Act does not conflict with the 1940 Act.

Business Combinations

Under the Maryland Business Combination Act, or the Business Combination Act, “business combinations” between a Maryland corporation and an interested stockholder or an affiliate of an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, share exchange or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. An interested stockholder is defined as:

| • |  | any person who beneficially owns 10.0% or more of the voting power of the corporation’s outstanding voting stock; or

| • |  | an affiliate or associate of the corporation who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10.0% or more of the voting power of the then outstanding stock of the corporation.

A person is not an interested stockholder under this statute if the board of directors approved in advance the transaction by which such stockholder otherwise would have become an interested stockholder. However, in approving a transaction, the board of directors may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by the board.

After the 5-year prohibition, any business combination between the Maryland corporation and an interested stockholder generally must be recommended by the board of directors of the corporation and approved by the affirmative vote of at least:

| • |  | 80.0% of the votes entitled to be cast by holders of outstanding shares of voting stock of the corporation; and

| • |  | two-thirds of the votes entitled to be cast by holders of voting stock of the corporation other than shares held by the interested stockholder with whom or with whose affiliate the business combination is to be effected or held by an affiliate or associate of the interested stockholder.

These super-majority vote requirements do not apply if the corporation’s common stockholders receive a minimum price, as defined under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares.

The statute permits various exemptions from its provisions, including business combinations that are exempted by the board of directors before the time that the interested stockholder becomes an interested stockholder. Moreover, it does not apply to a corporation, such as us, registered under the 1940 Act as a closed-end investment company unless the board of directors adopts a resolution that the corporation will be subject to the Business Combination Act. Our Board of Directors has not adopted and does not presently intend to adopt such a resolution.

Subtitle 8

Subtitle 8 of Title 3 of the Maryland General Corporation Law permits a Maryland corporation with a class of equity securities registered under the Securities Exchange Act of 1934 and at least three independent directors to elect to be subject by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contrary provision in the charter or bylaws, to any or all of five provisions:

| • |  | a classified board,

| • |  | a two-thirds vote requirement for removing a director,

| • |  | a requirement that the number of directors be fixed only by vote of the directors,

| • |  | a requirement that a vacancy on the board be filled only by the remaining directors and for the remainder of the full term of the class of directors and which the vacancy occurred and

| • |  | a majority requirement for the calling of a special meeting of stockholders.

Pursuant to Subtitle 8, we have elected to provide that vacancies on our Board of Directors may be filled only by the remaining directors and for the remainder of the full term of the directorship in which the vacancy occurred. Through provisions in our charter and bylaws unrelated to Subtitle 8, we already (a) require a two-thirds vote for the removal any director from the Board, (b) vest in the Board the exclusive power to fix the number of directorships and (c) require, unless called by our Board of Directors or certain of our officers, the request of stockholders entitled to cast a majority of the votes entitled to be cast on any matter that may properly be considered at a meeting of stockholders to call a special meeting.

Conflict with 1940 Act

Our bylaws provide that, if and to the extent that any provision of the Maryland General Corporation Law, or any provision of our charter or bylaws conflicts with any provision of the 1940 Act, the applicable provision of the 1940 Act will control.

DESCRIPTION OF OUR PREFERRED STOCK

Our charter authorizes our Board of Directors to classify and reclassify any unissued shares of stock into other classes or series of stock, including preferred stock. Prior to issuance of shares of each class or series, the Board of Directors is required by Maryland law and by our charter to set the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Thus, our Board of Directors could authorize the issuance of shares of preferred stock with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of our common stock or otherwise be in their best interest. You should note, however, that any issuance of preferred stock must comply with the requirements of the 1940 Act.

The 1940 Act generally requires that (1) immediately after issuance and before any distribution is made with respect to our common stock and before any purchase of common stock is made, such preferred stock together with all other senior securities must not exceed an amount equal to 50% of our total assets less liabilities not represented by indebtedness, and (2) the holders of shares of preferred stock, if any are issued, must be entitled as a class to elect two directors at all times and to elect a majority of the directors if distributions on such preferred stock are in arrears by two years or more. Certain matters under the 1940 Act require the separate vote of the holders of any issued and outstanding preferred stock. For example, holders of preferred stock would vote

137

##### Table of Contents

separately from the holders of common stock on a proposal to cease operations as a business development company. Further, the 1940 Act requires that any distributions we make on preferred stock be cumulative. We believe that the availability for issuance of preferred stock will provide us with increased flexibility in structuring future financings and acquisitions.

For any series of preferred stock that we may issue, our Board of Directors will determine and the prospectus supplement relating to such series will describe:

| • |  | the designation and number of shares of such series;

| • |  | the rate and time at which, and the preferences and conditions under which, any dividends will be paid on shares of such series, as well as whether such dividends are participating or non-participating;

| • |  | any provisions relating to convertibility or exchangeability of the shares of such series;

| • |  | the rights and preferences, if any, of holders of shares of such series upon our liquidation, dissolution or winding up of our affairs;

| • |  | the voting powers, if any, of the holders of shares of such series;

| • |  | any provisions relating to the redemption of the shares of such series;

| • |  | any limitations on our ability to pay dividends or make distributions on, or acquire or redeem, other securities while shares of such series are outstanding;

| • |  | any conditions or restrictions on our ability to issue additional shares of such series or other securities;

| • |  | if applicable, a discussion of certain U.S. federal income tax considerations; and

| • |  | any other relative power, preferences and participating, optional or special rights of shares of such series, and the qualifications, limitations or restrictions thereof.

The preferred stock may be either fixed rate preferred stock or variable rate preferred stock, which is sometimes referred to as “auction rate” preferred stock. All shares of preferred stock that we may issue will be identical and of equal rank except as to the particular terms thereof that may be fixed by our Board of Directors, and all shares of each series of preferred stock will be identical and of equal rank except as to the dates from which cumulative dividends, if any, thereon will be cumulative. If we issue shares of preferred stock, holders of such preferred stock will be entitled to receive cash dividends at an annual rate that will be fixed or will vary for the successive dividend periods for each series. In general, the dividend periods for fixed rate preferred stock can range from quarterly to weekly and are subject to extension. The dividend rate to be variable and determined for each dividend period.

DESCRIPTION OF OUR WARRANTS

The following is a general description of the terms of the warrants we may issue from time to time. Particular terms of any warrants we offer will be described in the prospectus supplement relating to such warrants.

We may issue warrants to purchase shares of our common stock, preferred stock or debt securities. Such warrants may be issued independently or together with shares of common or preferred stock or a specified principal amount of debt securities and may be attached or separate from such securities. We will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

138

##### Table of Contents

A prospectus supplement will describe the particular terms of any series of warrants we may issue, including the following:

| • |  | the title of such warrants;

| • |  | the aggregate number of such warrants;

| • |  | the price or prices at which such warrants will be issued;

| • |  | the currency or currencies, including composite currencies, in which the price of such warrants may be payable;

| • |  | if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;

| • |  | in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at which and the currency or currencies, including composite currencies, in which this principal amount of debt securities may be purchased upon such exercise;

| • |  | in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon exercise of one warrant and the price at which and the currency or currencies, including composite currencies, in which these shares may be purchased upon such exercise;

| • |  | the date on which the right to exercise such warrants shall commence and the date on which such right will expire;

| • |  | whether such warrants will be issued in registered form or bearer form;

| • |  | if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;

| • |  | if applicable, the date on and after which such warrants and the related securities will be separately transferable;

| • |  | information with respect to book-entry procedures, if any;

| • |  | the terms of the securities issuable upon exercise of the warrants;

| • |  | if applicable, a discussion of certain U.S. federal income tax considerations; and

| • |  | any other terms of such warrants, including terms, procedures and limitations relating to the exchange and exercise of such warrants.

We and the warrant agent may amend or supplement the warrant agreement for a series of warrants without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

Prior to exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including, in the case of warrants to purchase debt securities, the right to receive principal, premium, if any, or interest payments, on the debt securities purchasable upon exercise or to

139

##### Table of Contents

enforce covenants in the applicable indenture or, in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise any voting rights.

Under the 1940 Act, we may generally only offer warrants provided that (1) the warrants expire by their terms within ten years; (2) the exercise or conversion price is not less than the current market value at the date of issuance; (3) our stockholders authorize the proposal to issue such warrants, and our Board of Directors approves such issuance on the basis that the issuance is in our best interests and our stockholders; and (4) if the warrants are accompanied by other securities, the warrants are not separately transferable unless no class of such warrants and the securities accompanying them has been publicly distributed. The 1940 Act also provides that the amount of our voting securities that would result from the exercise of all outstanding warrants at the time of issuance may not exceed 25% of our outstanding voting securities. Our stockholders voted to allow us to issue warrants at our 2011 Annual Meeting of Stockholders.

DESCRIPTION OF OUR SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase common stock. Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any subscription rights offering to our stockholders, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such subscription rights offering. We will not offer transferable subscription rights to our stockholders at a price equivalent to less than the then current net asset value per share of common stock, excluding underwriting commissions, unless we first file a post-effective amendment that is declared effective by the SEC with respect to such issuance and the common stock to be purchased in connection with the rights represents no more than one-third of our outstanding common stock at the time such rights are issued. In connection with a subscription rights offering to our stockholders, we would distribute certificates evidencing the subscription rights and a prospectus supplement to our stockholders on the record date that we set for receiving subscription rights in such subscription rights offering. Our common stockholders will indirectly bear the expenses of such subscription rights offerings, regardless of whether our common stockholders exercise any subscription rights.

The applicable prospectus supplement would describe the following terms of subscription rights in respect of which this prospectus is being delivered:

| • |  | the title of such subscription rights;

| • |  | the exercise price or a formula for the determination of the exercise price for such subscription rights;

| • |  | the number or a formula for the determination of the number of such subscription rights issued to each stockholder;

| • |  | the extent to which such subscription rights are transferable;

| • |  | if applicable, a discussion of the material U.S. federal income tax considerations applicable to the issuance or exercise of such subscription rights;

| • |  | the date on which the right to exercise such subscription rights would commence, and the date on which such rights shall expire (subject to any extension);

| • |  | the extent to which such subscription rights include an over-subscription privilege with respect to unsubscribed securities;

140

##### Table of Contents

| • |  | if applicable, the material terms of any standby underwriting or other purchase arrangement that we may enter into in connection with the subscription rights offering; and

| • |  | any other terms of such subscription rights, including terms, procedures and limitations relating to the exchange and exercise of such subscription rights.

Exercise of Subscription Rights

Each subscription right would entitle the holder of the subscription right to purchase for cash such amount of shares of common stock or other securities at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the subscription rights offered thereby or another report filed with the SEC. Subscription rights may be exercised at any time up to the close of business on the expiration date for such subscription rights set forth in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised subscription rights would become void. We have not previously completed such an offering of subscription rights.

Subscription rights may be exercised as set forth in the prospectus supplement relating to the subscription rights offered thereby. Upon receipt of payment and the subscription rights certificate properly completed and duly executed at the corporate trust office of the subscription rights agent or any other office indicated in the prospectus supplement, we will forward, as soon as practicable, the shares of common stock or other securities purchasable upon such exercise. We may determine to offer any unsubscribed offered securities directly to stockholders, persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting or other arrangements, as set forth in the applicable prospectus supplement.

DESCRIPTION OF OUR DEBT SECURITIES

In March 2012, we issued $69.0 million in aggregate principal amount of our 7.00% senior notes due 2019, or the “Notes,” for net proceeds of approximately $66.6 million after deducting the underwriting discount and offering expenses. The Notes are listed on the New York Stock Exchange under the symbol “TCC.” The Notes will mature on March 15, 2019. The principal payable at maturity will be 100.00% of the aggregate principal amount. The interest rate of the Notes is 7.00% per year and will be paid every March 15, June 15, September 15 and December 15 commencing June 15, 2012 and the regular record dates for interest payments will be every March 1, June 1, September 1 and December 1 commencing June 1, 2012. If an interest payment date falls on a non-business day, the applicable interest payment will be made on the next business day and no additional interest will accrue as a result of such delayed payment. The indenture does not contain any provisions that give the holder of our Notes protection in the event we issue a large amount of debt or we are acquired by another entity. The initial interest period will be the period from and including the issuance date, to, but excluding, the initial interest payment date, and the subsequent interest periods will be the periods from and including an interest payment date to, but excluding, the next interest payment date or the stated maturity date, as the case may be. We issued the Notes in denominations of $25.00 and integral multiples of $25.00 in excess thereof. The Notes are not subject to any sinking fund and holders of the Notes do not have the option to have the Notes repaid prior to the stated maturity date.

The Notes are our direct unsecured obligations and rank: (i) pari passu with our future senior unsecured indebtedness; (ii) senior to any of our future indebtedness that expressly provides it is subordinated to the Notes; (iii) effectively subordinated to all of our existing and future secured indebtedness (including indebtedness that is initially unsecured to which we subsequently grant security), to the extent of the value of the assets securing such indebtedness, including without limitation, borrowings under our $75.0 million revolving credit facility; and (iv) structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries, including without limitation, the indebtedness of the Company’s two SBIC subsidiaries.

141

##### Table of Contents

The Notes may be redeemed in whole or in part at any time or from time to time at our option on or after March 15, 2015 upon not less than 30 days nor more than 60 days written notice by mail prior to the date fixed for redemption thereof, at a redemption price of $25.00 per Note plus accrued and unpaid interest payments otherwise payable for the then-current quarterly interest period accrued to the date fixed for redemption.

The holder of our Notes may be prevented from exchanging or transferring the Notes when they are subject to redemption. In case any Notes are to be redeemed in part only, the redemption notice will provide that, upon surrender of such Note, the holder will receive, without a charge, a new Note or Notes of authorized denominations representing the principal amount of such holder’s remaining unredeemed Notes. Any exercise of our option to redeem the Notes will be done in compliance with the 1940 Act.

If we redeem only some of the Notes, The Bank of New York Mellon Trust Company, N.A., the trustee for the Notes, or the Trustee, will determine the method for selection of the particular Notes to be redeemed, in accordance with the 1940 Act to the extent applicable and in accordance with the rules of any national securities exchange or quotation system on which the Notes are listed. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes called for redemption.

The Trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the Trustee protection reasonably satisfactory to it from expenses and liability (called an “indemnity”). If reasonable indemnity is provided, the holders of a majority in principal amount of the Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the Trustee. The Trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or event of default. Holders of the Notes may bypass the Trustee and bring a lawsuit or other formal legal action or take other steps to enforce rights or protect interests relating to the Notes in certain circumstances.

Under the indenture governing the Notes, there are certain events of default, the occurrence of which may lead to the Notes being due and payable immediately. An event of default under the indenture could have a material adverse effect on our business, financial conditions and results of operations.

We may issue additional debt securities in one or more series in the future which, if publicly offered, will be under an indenture to be entered into between us and a trustee. The specific terms of each series of debt securities we publicly offer will be described in the particular prospectus supplement relating to that series. The prospectus supplement may or may not modify the general terms found in this prospectus and will be filed with the SEC. For a complete description of the terms of a particular series of debt securities, you should read both this prospectus and the prospectus supplement relating to that particular series. The description below is a summary with respect to future debt securities we may issue and not a summary of the Notes.

As required by federal law for all bonds and notes of companies that are publicly offered, the debt securities are governed by a document called an “indenture.” An indenture is a contract between us and The Bank of New York Mellon Trust Company, N.A., a financial institution acting as trustee on behalf of investors, and is subject to and governed by the Trust Indenture Act of 1939, as amended. The trustee has two main roles. First, the trustee can enforce rights of investors against us if we default. There are some limitations on the extent to which the trustee acts on behalf of investors. Second, the trustee performs certain administrative duties for us.

Because this section is a summary, it does not describe every aspect of the debt securities we have and may issue and the indenture. We urge you to read the indenture because it, and not this description, defines rights of a holder of debt securities. We have filed the form of the indenture with the SEC. See “Available Information” for information on how to obtain a copy of the indenture.

142

##### Table of Contents

If we offer additional debt securities in the future, the prospectus supplement, which will accompany this prospectus, will describe the particular series of debt securities being offered, including, among other things:

| • |  | the designation or title of the series of debt securities;

| • |  | the total principal amount of the series of debt securities;

| • |  | the percentage of the principal amount at which the series of debt securities will be offered;

| • |  | the date or dates on which principal will be payable;

| • |  | the rate or rates (which may be either fixed or variable) and/or the method of determining such rate or rates of interest, if any;

| • |  | the date or dates from which any interest will accrue, or the method of determining such date or dates, and the date or dates on which any interest will be payable;

| • |  | the terms for redemption, extension or early repayment, if any;

| • |  | the currencies in which the series of debt securities are issued and payable;

| • |  | whether the amount of payments of principal, premium or interest, if any, on a series of debt securities will be determined with reference to an index, formula or other method (which could be based on one or more currencies, commodities, equity indices or other indices) and how these amounts will be determined;

| • |  | the place or places of payment, transfer, conversion and/or exchange of the debt securities;

| • |  | the denominations in which the offered debt securities will be issued;

| • |  | the provision for any sinking fund;

| • |  | any restrictive covenants;

| • |  | any events of default;

| • |  | whether the series of debt securities are issuable in certificated form;

| • |  | any provisions for defeasance or covenant defeasance;

| • |  | any special federal income tax implications, including, if applicable, federal income tax considerations relating to original issue discount;

| • |  | whether and under what circumstances we will pay additional amounts in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities rather than pay the additional amounts (and the terms of this option);

| • |  | any provisions for convertibility or exchangeability of the debt securities into or for any other securities;

| • |  | whether the debt securities are subject to subordination and the terms of such subordination;

| • |  | the listing, if any, on a securities exchange; and

| • |  | any other material terms.

143

##### Table of Contents

The debt securities may be secured or unsecured obligations. Under the provisions of the 1940 Act, we are permitted, as a business development company, to issue debt only in amounts such that our asset coverage, as defined in the 1940 Act, equals at least 200% after each issuance of debt. Unless the prospectus supplement, which will accompany this prospectus, states otherwise, principal (and premium, if any) and interest, if any, will be paid by us in immediately available funds.

General

The indenture provides that any debt securities proposed to be sold under this prospectus and the applicable prospectus supplement (“offered debt securities”) and any debt securities issuable upon the exercise of warrants or upon conversion or exchange of other offered securities (“underlying debt securities”), may be issued under the indenture in one or more series.

For purposes of this prospectus, any reference to the payment of principal of or premium or interest, if any, on debt securities will include additional amounts if required by the terms of the debt securities.

The indenture does not limit the amount of debt securities that may be issued thereunder from time to time. Debt securities issued under the indenture, when a single trustee is acting for all debt securities issued under the indenture, are called the “indenture securities.” The indenture also provides that there may be more than one trustee thereunder, each with respect to one or more different series of indenture securities. See “Resignation of Trustee” below. At a time when two or more trustees are acting under the indenture, each with respect to only certain series, the term “indenture securities” means the one or more series of debt securities with respect to which each respective trustee is acting. In the event that there is more than one trustee under the indenture, the powers and trust obligations of each trustee described in this prospectus will extend only to the one or more series of indenture securities for which it is trustee. If two or more trustees are acting under the indenture, then the indenture securities for which each trustee is acting would be treated as if issued under separate indentures.

The indenture does not contain any provisions that give the holder of debt securities protection in the event we issue a large amount of debt or we are acquired by another entity.

We refer you to the applicable prospectus supplement for information with respect to any deletions from, modifications of or additions to the Events of Default or our covenants that are described below, including any addition of a covenant or other provision providing event risk or similar protection.

We have the ability to issue indenture securities with terms different from those of indenture securities previously issued and, without the consent of the holders thereof, to reopen a previous issue of a series of indenture securities and issue additional indenture securities of that series unless the reopening was restricted when that series was created.

We expect that we will usually issue debt securities in book entry only form represented by global securities and will specify the method of issuance in the applicable prospectus supplement.

Conversion and Exchange

If any debt securities are convertible into or exchangeable for other securities, the applicable prospectus supplement will explain the terms and conditions of the conversion or exchange, including the conversion price or exchange ratio (or the calculation method), the conversion or exchange period (or how the period will be determined), whether conversion or exchange will be mandatory or at the option of the holder or us, provisions for adjusting the conversion price or the exchange ratio and provisions affecting conversion or exchange in the event of the redemption of the underlying debt securities. These terms may also include provisions under which the number or amount of other securities to be received by the holders of the debt securities upon conversion or exchange would be calculated according to the market price of the other securities as of a time stated in the applicable prospectus supplement.

144

##### Table of Contents

Payment

Unless otherwise specified in the applicable prospectus supplement, we will pay interest to the person listed in the trustee’s records as the owner of the debt security at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the debt security on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the “record date.” Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling the debt securities must work out between themselves the appropriate purchase price. The most common manner is to adjust the sales price of the debt securities to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called “accrued interest.”

Payments on Global Securities

We will make payments on a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder’s right to those payments will be governed by the rules and practices of the depositary and its participants.

Payment When Offices Are Closed

If any payment is due on a debt security on a day that is not a business day, we will make the payment on the next day that is a business day. Payments made on the next business day in this situation will be treated under the indenture as if they were made on the original due date, except as otherwise indicated in the attached prospectus supplement. Such payment will not result in a default under any debt security or the indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a business day.

Book-entry and other indirect holders should consult their banks or brokers for information on how they will receive payments on their debt securities.

Events of Default

Investors will have rights if an Event of Default occurs with respect to the debt securities of their respective series and the Event of Default is not cured, as described later in this subsection.

The term “Event of Default” with respect to the relevant series of debt securities means any of the following (unless the applicable prospectus supplement or supplemental indenture relating to such debt securities states otherwise):

| • |  | We do not pay the principal of any debt security of the series on its due date.

| • |  | We do not pay interest on any debt security of the series when due, and such default is not cured within 30 days.

| • |  | We remain in breach of any other covenant with respect to the debt securities of the series for 60 days after we receive a written notice of default stating we are in breach. The notice must be sent by either the trustee or holders of at least 25.00% of the principal amount of debt securities of the issuer.

| • |  | We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur and, in the case of certain orders or decrees entered against us under any bankruptcy law, such order or decree remains undischarged or unstayed for a period of 60 days.

| • |  | On the last business day of each of twenty-four consecutive calendar months, we have an asset coverage of less than 100.00%.

| • |  | Any other Event of Default with respect to debt securities of the series described in the applicable prospectus supplement or supplemental indenture occurs.

145

##### Table of Contents

An Event of Default for a particular series of debt securities does not necessarily constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. The trustee may withhold notice to the holders of debt securities of any default, except in the payment of principal, premium or interest, if it considers the withholding of notice to be in the best interests of the holders.

Remedies if an Event of Default Occurs

Unless the applicable prospectus supplement specifies otherwise, if an Event of Default has occurred and has not been cured, the trustee or the holders of at least 25.00% in principal amount of the debt securities of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. In certain circumstances, a declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the debt securities of the affected series.

The trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection reasonably satisfactory to it from expenses and liability (called an “indemnity”). If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. The trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or Event of Default.

Before a holder of debt securities is allowed to bypass the trustee and bring a lawsuit or other formal legal action or take other steps to enforce the holder’s rights or protect the holder’s interests relating to the debt securities, the following must occur:

| • |  | The holder must give the trustee written notice that an Event of Default has occurred and remains uncured.

| • |  | The holders of at least 25.00% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action.

| • |  | The trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

| • |  | The holders of a majority in principal amount of the debt securities must not have given the trustee a direction inconsistent with the above notice during that 60 day period.

However, the holder is entitled at any time to bring a lawsuit for the payment of money due on the holder’s debt securities on or after the due date.

Holders of a majority in principal amount of the debt securities of the affected series may waive any past defaults other than:

| • |  | the payment of principal, any premium or interest; or

| • |  | in respect of a covenant that cannot be modified or amended without the consent of each holder.

Book-entry and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration of maturity.

Each year, we will furnish to the trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the debt securities, or else specifying any default.

Merger or Consolidation

Under the terms of the indenture, we are generally permitted to consolidate or merge with another entity. We are also permitted to sell all or substantially all of our assets to another entity. However, unless the prospectus supplement relating to certain debt securities states otherwise, we may not take any of these actions unless all the following conditions are met:

| • |  | Where we merge out of existence or sell our assets, the resulting entity must agree to be legally responsible for our obligations under the debt securities.

| • |  | The merger or sale of assets must not cause a default on the debt securities and we must not already be in default (unless the merger or sale would cure the default). For purposes of this no-default test, a default would include an Event of Default that has occurred and has not been cured, as described under “Events of Default” above. A default for this purpose would also include any event that would be an Event of Default if the requirements for giving us notice of default or our default having to exist for a specified period of time were disregarded.

| • |  | We must deliver certain certificates and documents to the trustee.

| • |  | We must satisfy any other requirements specified in the prospectus supplement relating to a particular series of debt securities.

Modification or Waiver

There are three types of changes we can make to the indenture and the debt securities issued thereunder.

Changes Requiring the Holder’s Approval

First, there are changes that we cannot make to the debt securities without approval from each affected holder. The following is a list of those types of changes:

| • |  | change the stated maturity of the principal of or interest on a debt security;

| • |  | reduce any amounts due on a debt security;

| • |  | reduce the amount of principal payable upon acceleration of the maturity of a security following a default;

| • |  | adversely affect any right of repayment at the holder’s option;

| • |  | change the place (except as otherwise described in the prospectus or prospectus supplement) or currency of payment on a debt security;

| • |  | impair the holder’s right to sue for payment;

| • |  | adversely affect any right to convert or exchange a debt security in accordance with its terms;

| • |  | modify the subordination provisions in the indenture in a manner that is adverse to holders of the debt securities;

| • |  | reduce the percentage of holders of debt securities whose consent is needed to modify or amend the indenture;

147

##### Table of Contents

| • |  | reduce the percentage of holders of debt securities whose consent is needed to waive compliance with certain provisions of the indenture or to waive certain defaults; and

| • |  | modify any other material aspect of the provisions of the indenture dealing with supplemental indentures, modification and waiver of past defaults, changes to the quorum or voting requirements or the waiver of certain covenants.

Changes Not Requiring Approval

The second type of change does not require any vote by the holders of the debt securities. This type is limited to clarifications and certain other changes that would not adversely affect holders of the outstanding debt securities in any material respect.

Changes Requiring Majority Approval

Any other change to the indenture and the debt securities would require the following approval:

| • |  | If the change affects only one series of debt securities, it must be approved by the holders of a majority in principal amount of that series.

| • |  | If the change affects more than one series of debt securities issued under the same indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose.

The holders of a majority in principal amount of a series of debt securities issued under the indenture may waive our compliance with some of our covenants applicable to that series.

Further Details Concerning Voting

Debt securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption. Debt securities will also not be eligible to vote if they have been fully defeased as described later under “Defeasance—Full Defeasance.”

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding indenture securities that are entitled to vote or take other action under the indenture. If we set a record date for a vote or other action to be taken by holders of one or more series, that vote or action may be taken only by persons who are holders of outstanding indenture securities of those series on the record date and must be taken within eleven months following the record date.

Book-entry and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the debt securities or request a waiver.

Defeasance

The following provisions will be applicable to each series of debt securities unless we state in the applicable prospectus supplement that the provisions of covenant defeasance and full defeasance will not be applicable to that series.

Covenant Defeasance

Under applicable law, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the particular series was issued. This is called “covenant defeasance.” In

148

##### Table of Contents

that event, the holder of debt securities would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay debt securities of the holders. In order to achieve covenant defeasance, the following conditions must be satisfied:

| • |  | If the debt securities of the particular series are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of such debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their due dates.

| • |  | We must deliver to the trustee a legal opinion of our counsel confirming that, under current U.S. federal income tax law, we may make the above deposit without causing holders to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity.

| • |  | Defeasance must not result in a breach or violation of, or result in a default under, the indenture or any of our other material agreements or instruments.

| • |  | No default or event of default with respect to the debt securities shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days.

We must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act and a legal opinion and officers’ certificate stating that all conditions precedent to covenant defeasance have been complied with.

If we accomplish covenant defeasance, a holder can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit or the trustee is prevented from making payment. For example, if one of the remaining Events of Default occurred (such as our bankruptcy) and the debt securities became immediately due and payable, there might be a shortfall. Depending on the event causing the default, a holder may not be able to obtain payment of the shortfall.

Full Defeasance

If there is a change in U.S. federal tax law, as described below, we can legally release ourselves from all payment and other obligations on the debt securities of a particular series (called “full defeasance”) if the following conditions are satisfied in order for a holder to be repaid:

| • |  | If the debt securities of the particular series are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of such debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates.

| • |  | We must deliver to the trustee a legal opinion confirming that there has been a change in current U.S. federal tax law or an IRS ruling that allows us to make the above deposit without causing a holder to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves at maturity. Under current U.S. federal tax law, the deposit and our legal release from the debt securities would be treated as though we paid the holder, his or her respective share of the cash and notes or bonds at the time the cash and notes or bonds were deposited in trust in exchange for the holder’s debt securities and the holder would recognize gain or loss on the debt securities at the time of the deposit.

| • |  | We must deliver to the trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act and a legal opinion and officers’ certificate stating that all conditions precedent to defeasance have been complied with.

149

##### Table of Contents

| • |  | Defeasance must not result in a breach or violation of, or constitute a default under, the indenture or any of our other material agreements or instruments.

| • |  | No default or event of default with respect to the debt securities shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days.

If we ever did accomplish full defeasance, as described above, a holder would have to rely solely on the trust deposit for repayment of the debt securities. A holder could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent.

Resignation of Trustee

The trustee may resign or be removed with respect to one or more series of indenture securities provided that a successor trustee is appointed to act with respect to those series. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

Indenture Provisions — Subordination and Senior Indebtedness

Upon any distribution of our assets upon our dissolution, winding up, liquidation or reorganization, the payment of the principal of (and premium, if any) and interest, if any, on any indenture securities denominated as subordinated debt securities is to be subordinated to the extent provided in the indenture in right of payment to the prior payment in full of all Senior Indebtedness (as defined below), but our obligation to a holder to make payment of the principal of (and premium, if any) and interest, if any, on such subordinated debt securities will not otherwise be affected. In addition, no payment on account of principal (or premium, if any), sinking fund or interest, if any, may be made on such subordinated debt securities at any time unless full payment of all amounts due in respect of the principal (and premium, if any), sinking fund and interest on Senior Indebtedness has been made or duly provided for in money or money’s worth.

In the event that, notwithstanding the foregoing, any payment by us is received by the trustee in respect of subordinated debt securities or by the holders of any of such subordinated debt securities before all Senior Indebtedness is paid in full, the payment or distribution must be paid over to the holders of the Senior Indebtedness or on their behalf for application to the payment of all the Senior Indebtedness remaining unpaid until all the Senior Indebtedness has been paid in full, after giving effect to any concurrent payment or distribution to the holders of the Senior Indebtedness. Subject to the payment in full of all Senior Indebtedness upon this distribution by us, the holders of such subordinated debt securities will be subrogated to the rights of the holders of the Senior Indebtedness to the extent of payments made to the holders of the Senior Indebtedness out of the distributive share of such subordinated debt securities.

By reason of this subordination, in the event of a distribution of our assets upon our insolvency, certain of our senior creditors may recover more, ratably, than holders of any subordinated debt securities.

“Senior Indebtedness” is defined in the indenture as the principal of (and premium, if any) and unpaid interest on:

| • |  | our indebtedness (including indebtedness of others guaranteed by us), whenever created, incurred, assumed or guaranteed, for money borrowed (other than indenture securities issued under the indenture and denominated as subordinated debt securities), unless in the instrument creating or evidencing the same or under which the same is outstanding it is provided that this indebtedness is not senior or prior in right of payment to the subordinated debt securities, and

| • |  | renewals, extensions, modifications and refinancings of any of this indebtedness.

150

##### Table of Contents

If this prospectus is being delivered in connection with the offering of a series of indenture securities denominated as subordinated debt securities, the accompanying prospectus supplement will set forth the approximate amount of our Senior Indebtedness outstanding as of a recent date.

The Trustee Under the Indenture

The Bank of New York Mellon Trust Company, N.A., serves as the trustee under the indenture.

Certain Considerations Relating to Foreign Currencies

Debt securities denominated or payable in foreign currencies may entail significant risks. These risks include the possibility of significant fluctuations in the foreign currency markets, the imposition or modification of foreign exchange controls and potential illiquidity in the secondary market. These risks will vary depending upon the currency or currencies involved and will be more fully described in the applicable prospectus supplement.

Book-Entry Procedures

Unless otherwise specified in the applicable prospectus supplement, the Depository Trust Company (“DTC”) will act as securities depositary for the debt securities. The debt securities will be issued as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered certificate will be issued for the debt securities, in the aggregate principal amount of such issue, and will be deposited with DTC.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments from over 100 countries that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”).

DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has Standard & Poor’s Ratings Services’ highest rating: AAA. The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.

Purchases of debt securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of each security, or the “Beneficial Owner,” is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners

151

##### Table of Contents

will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities is discontinued.

To facilitate subsequent transfers, all debt securities deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the debt securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such debt securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the debt securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Redemption proceeds, distributions, and interest payments on the debt securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC nor its nominee, the trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of us or the trustee, but disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

DTC may discontinue providing its services as securities depository with respect to the debt securities at any time by giving reasonable notice to us or to the trustee. Under such circumstances, in the event that a successor securities depository is not obtained, certificates are required to be printed and delivered. We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

##### Table of Contents

DESCRIPTION OF OUR UNITS

As will be specified in the applicable prospectus supplement, we may issue units comprised of one or more of the other securities described in this prospectus in any combination and offer such units to the public. Each unit may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The prospectus supplement will describe:

| • |  | the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be held or transferred separately;

| • |  | a description of the terms of any unit agreement governing the units;

| • |  | a description of the provisions for the payment, settlement, transfer or exchange of the units; and

| • |  | whether the units will be issued in fully registered or global form.

We will ensure that any issuance of third party securities other than U.S. Treasuries complies with SEC interpretive guidance.

If a unit includes a share of common stock, the public offering price for the unit will reflect a price per share of common stock that equals or exceeds our then current net asset value per share, unless the requirements of Section 63 of the 1940 Act have been satisfied. Section 63 permits us to sell shares of common stock below our then current net asset value per share if: (1) the majority of our Board of Directors approves the offering as being in the best interests of us and our stockholders, (2) a majority of our stockholders (including a majority of our stockholders who are not affiliated persons of us) have approved the issuance of common stock below the then current net asset value per share in the 12 months preceding the offering and (3) the offering price closely approximates the market value of the common stock. If the Section 63 requirements are met, the price per share of common stock included in a unit may be below the Company’s then current net asset value per share. See “Sales of Common Stock Below Net Asset Value” for more information.

Units may also include warrants to purchase shares of our common stock in the future. We may generally only offer such warrants if (1) the warrants expire by their terms within ten years, (2) the exercise price is not less than the market value of our common stock at the date of issuance, (3) the exercise prices is not less than the then current net asset value per share of our common stock (unless the Section 63 requirements are met), (4) our stockholders authorize the proposal to issue such warrants, and our Board of Directors approves such issuance on the basis that the issuance is in the best interests of us and our stockholders and (5) if the warrants are accompanied by other securities, the warrants are not separately transferable unless no class of such warrants and the securities accompanying them has been publicly distributed. The 1940 Act also provides that the amount of our voting securities that would result from the exercise of all outstanding warrants at the time of issuance may not exceed 25% of our outstanding voting securities.

Units may also include subscription rights to purchase shares of our common stock. We will not offer transferable subscription rights in a unit providing for subscription at a price below the then current net asset value per share of common stock, excluding underwriting commissions, unless we first file a post-effective amendment that is declared effective by the SEC with respect to such issuance and the common stock to be purchased in connection with the rights represents no more than one-third of our outstanding common stock at the time such rights are issued.

Units may also include debt securities. If such debt securities are convertible into shares of our common stock, the exercise price for such conversion will not be less than the net asset value per share of our common stock at the time of issuance of the unit (unless the Section 63 requirements are met).

153

##### Table of Contents

The descriptions of the units and any applicable underlying security or pledge or depositary arrangements in this prospectus and in any prospectus supplement are summaries of the material provisions of the applicable agreements and are subject to, and qualified in their entirety by reference to, the terms and provisions of the applicable agreements, forms of which have been or will be filed as exhibits to the registration statement of which this prospectus forms a part.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a general summary of the material U.S. federal income tax considerations applicable to us and to an investment in our shares. This summary does not purport to be a complete description of the income tax considerations applicable to us or to investors in such an investment. For example, we have not described tax consequences that we assume to be generally known by investors or certain considerations that may be relevant to certain types of holders subject to special treatment under U.S. federal income tax laws, including stockholders subject to the alternative minimum tax, tax-exempt organizations, insurance companies, dealers in securities, pension plans and trusts, financial institutions, U.S. stockholders (as defined below) whose functional currency is not the U.S. dollar, persons who mark-to-market our shares and persons who hold our shares as part of a “straddle,” “hedge” or “conversion” transaction. This summary assumes that investors hold shares of our common stock as capital assets (within the meaning of the Code). The discussion is based upon the Code, Treasury regulations, and administrative and judicial interpretations, each as of the date of this prospectus and all of which are subject to change, possibly retroactively, which could affect the continuing validity of this discussion. We have not sought and do not intend to seek any ruling from the Internal Revenue Service, or the IRS, regarding any offer and sale of our common stock under this prospectus. This summary does not discuss any aspects of U.S. estate or gift tax or foreign, state or local tax. It does not discuss the special treatment under U.S. federal income tax laws that could result if we invested in tax-exempt securities or certain other investment assets.

For purposes of our discussion, a “U.S. stockholder” means a beneficial owner of shares of our common stock that is for U.S. federal income tax purposes:

| • |  | a citizen or individual resident of the United States;

| • |  | a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

| • |  | an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

| • |  | a trust if (1) a U.S. court is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) it has a valid election in place to be treated as a U.S. person.

For purposes of our discussion, a “Non-U.S. stockholder” means a beneficial owner of shares of our common stock that is neither a U.S. stockholder nor a partnership (including an entity treated as a partnership for U.S. federal income tax purposes).

If a partnership (including an entity treated as a partnership for U.S. federal income tax purposes) holds shares of our common stock, the tax treatment of a partner or member of the partnership will generally depend upon the status of the partner and the activities of the partnership. A prospective stockholder that is a partner in a partnership holding shares of our common stock should consult his, her or its tax advisors with respect to the purchase, ownership and disposition of shares of our common stock.

Tax matters are very complicated and the tax consequences to an investor of an investment in our shares will depend on the facts of his, her or its particular situation. We encourage investors to consult their own tax advisors regarding the specific consequences of such an investment, including tax reporting requirements, the applicability of U.S. federal, state, local and foreign tax laws, eligibility for the benefits of any applicable tax treaty and the effect of any possible changes in the tax laws.

Taxation in Connection with Holding Securities other than our Common Stock

We intend to describe in any prospectus supplement related to the offering of preferred stock, units, debt securities, warrants or rights offerings to purchase our common stock or preferred stock, the U.S. federal income tax considerations applicable to such securities as will be sold by us pursuant to that prospectus supplement, including the taxation of any debt securities that will be sold at an original issue discount or acquired with market discount or amortizable bond premium and the tax treatment of sales, exchanges or retirements of our debt securities.

Election to be Taxed as a RIC

We have qualified and elected to be treated as a RIC under Subchapter M of the Code commencing with our taxable year ended December 31, 2007. As a RIC, we generally are not subject to corporate-level U.S. federal income taxes on any income that we distribute to our stockholders from our tax earnings and profits. 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 income plus the excess, if any, of realized net short-term capital gain over realized net long-term capital loss, or the Annual Distribution Requirement. Even if we qualify as a RIC, we generally will be subject to corporate-level U.S. federal income tax on our undistributed taxable income and could be subject to U.S. federal excise, state, local and foreign taxes.

Taxation as a RIC

Provided that 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 investment company taxable income and net capital gain (which we define as net long-term capital gain in excess of net short-term capital loss) that we timely distribute to stockholders. We will be subject to U.S. federal income tax at the regular corporate rates on any income or capital gain not distributed (or deemed distributed) to our stockholders.

We will be subject to a 4% nondeductible U.S. federal excise tax on certain undistributed income of RICs unless we distribute in a timely manner an amount at least equal to the sum of (1) 98.0% of our ordinary income for each calendar year, (2) 98.2% of our capital gain net income for each calendar year and (3) any income recognized, but not distributed, in preceding years and on which we paid no U.S. federal income tax. We generally will endeavor in each taxable year to avoid any U.S. federal excise tax on our earnings.

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

| • |  | elect to be treated as a RIC;

| • |  | meet the Annual Distribution Requirement;

| • |  | qualify to be treated as a BDC or be registered as a management investment company 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 or other disposition of stock, securities or currencies, other income derived with respect to our business of investing in such stock, securities or currencies and net income derived from an interest in a “qualified publicly traded partnership” (as defined in the Code), or the 90% Income Test; and

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

155

##### Table of Contents

| • |  | 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 (which for these purposes includes the equity securities of a “qualified publicly traded partnership”); 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 tax rules, by us and that are engaged in the same or similar or related trades or businesses or (iii) of one or more “qualified publicly traded partnerships,” or the Diversification Tests.

To the extent that we invest in entities treated as partnerships for U.S. federal income tax purposes (other than a “qualified publicly traded partnership”), we generally must include the items of gross income derived by the partnerships for purposes of the 90% Income Test, and the income that is derived from a partnership (other than, a “qualified publicly traded partnership”) will be treated as qualifying income for purposes of the 90% Income Test only to the extent that such income is attributable to items of income of the partnership which would be qualifying income if realized by us directly. In addition, we generally must take into account our proportionate share of the assets held by partnerships (other than a “qualified publicly traded partnership”) in which we are a partner for purposes of the Diversification Tests.

In order to meet the 90% Income Test, we have established several special purpose corporations, and in the future may establish additional such corporations, to hold assets from which we do not anticipate earning dividend, interest or other qualifying income under the 90% Income Test (the “Taxable Subsidiaries”). Any investments held through the Taxable Subsidiaries are generally subject to U.S. federal income and other taxes, and therefore we can expect to achieve a reduced after-tax yield on such investments.

We may be required to recognize taxable income in circumstances in which we do not receive a corresponding payment in cash. For example, if we hold debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments with payment-in-kind interest or, in certain cases, increasing interest rates or issued with warrants), 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 deferred loan origination fees that are paid after origination of the loan or are paid in non-cash compensation such as warrants or stock. We anticipate that a portion of our income may constitute original issue discount or other income required to be included in taxable income prior to receipt of cash.

Because any original issue discount or other amounts accrued will be included in our investment company taxable income for the year of the 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. As a result, we may have difficulty meeting the annual distribution requirement necessary to obtain and maintain RIC tax treatment under the Code. 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 income tax.

Furthermore, a portfolio company in which we invest may face financial difficulty that requires us to work-out, modify or otherwise restructure our investment in the portfolio company. Any such restructuring may result in unusable capital losses and future non-cash income. Any restructuring may also result in our recognition of a substantial amount of non-qualifying income for purposes of the 90% Income Test, such as cancellation of indebtedness income in connection with the work-out of a leveraged investment (which, while not free from doubt, may be treated as non-qualifying income) or the receipt of other non-qualifying income.

Gain or loss realized by us from warrants acquired by us as well as any loss attributable to the lapse of such warrants generally will be treated as capital gain or loss. Such gain or loss generally will be long-term or short-term, depending on how long we held a particular warrant.

Any investment in non-U.S. securities may be subject to non-U.S. income, withholding and other taxes. In that case, our yield on those securities would be decreased. Stockholders will generally not be entitled to claim a credit or deduction with respect to non-U.S. taxes paid by us.

If we purchase shares in a “passive foreign investment company,” or PFIC, we may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by us to our stockholders. Additional charges in the nature of interest may be imposed on us in respect of deferred taxes arising from such distributions or gains. If we invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Code, or QEF, in lieu of the foregoing requirements, we will be required to include in income each year a portion of the ordinary earnings and net capital gain of the QEF, even if such income is not distributed to it. Alternatively, we can elect to mark-to-market at the end of each taxable year our shares in a PFIC; in this case, we will recognize as ordinary income any increase in the value of such shares and as ordinary loss any decrease in such value to the extent it does not exceed prior increases included in income. Under either election, we may be required to recognize in a year income in excess of our distributions from PFICs and our proceeds from dispositions of PFIC stock during that year, and such income will nevertheless be subject to the Annual Distribution Requirement and will be taken into account for purposes of the 4% excise tax.

Under Section 988 of the Code, gain or loss attributable to fluctuations in exchange rates between the time we accrue income, expenses, or other liabilities denominated in a foreign currency and the time we actually collect such income or pay such expenses or liabilities are generally treated as ordinary income or loss. Similarly, gain or loss on foreign currency forward contracts and the disposition of debt denominated in a foreign currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss.

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 while our debt obligations and other senior securities are outstanding unless certain “asset coverage” tests are met. See “Regulation — Qualifying Assets” and “Regulation — 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 to avoid the excise tax, we may make such dispositions at times that, from an investment standpoint, are not advantageous.

If we fail to satisfy the Annual Distribution Requirement or otherwise fail to qualify as a RIC in any taxable year, we will be subject to tax in that year on all of our taxable income, regardless of whether we make any distributions to our stockholders. In that case, all of such income will be subject to corporate-level U.S. federal income tax, reducing the amount available to be distributed to our stockholders. See “— Failure To Obtain RIC Tax Treatment.”

As a RIC, we are not allowed to carry forward or carry back a net operating loss for purposes of computing our investment company taxable income in other taxable years. U.S. federal income tax law generally permits a RIC to carry forward (i) the excess of its net short-term capital loss over its net long-term capital gain for a given year as a short-term capital loss arising on the first day of the following year and (ii) the excess of its net long-term capital loss over its net short-term capital gain for a given year as a long- term capital loss arising on the first day of the following year. However, future transactions we engage in may cause our ability to use any capital loss carryforwards, and unrealized losses once realized, to be limited under Section 382 of the Code. Certain of our investment practices may be subject to special and complex U.S. federal income tax provisions that may, among other things, (i) disallow, suspend or otherwise limit the allowance of certain losses or

157

##### Table of Contents

deductions, (ii) convert lower taxed long-term capital gain and qualified dividend income into higher taxed short-term capital gain or ordinary income, (iii) convert an ordinary loss or a deduction into a capital loss (the deductibility of which is more limited), (iv) cause us to recognize income or gain without a corresponding receipt of cash, (v) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur, (vi) adversely alter the characterization of certain complex financial transactions, and (vii) produce income that will not be qualifying income for purposes of the 90% Income Test. We will monitor our transactions and may make certain tax elections in order to mitigate the effect of these provisions.

As described above, to the extent that we invest in equity securities of entities that are treated as partnerships for U.S. federal income tax purposes, the effect of such investments for purposes of the 90% Income Test and the Diversification Tests will depend on whether or not the partnership is a “qualified publicly traded partnership” (as defined in the Code). If the partnership is a “qualified publicly traded partnership,” the net income derived from such investments will be qualifying income for purposes of the 90% Income Test and will be “securities” for purposes of the Diversification Tests. If the partnership, however, is not treated as a “qualified publicly traded partnership,” then the consequences of an investment in the partnership will depend upon the amount and type of income and assets of the partnership allocable to us. The income derived from such investments may not be qualifying income for purposes of the 90% Income Test and, therefore, could adversely affect our qualification as a RIC. We intend to monitor our investments in equity securities of entities that are treated as partnerships for U.S. federal income tax purposes to prevent our disqualification as a RIC.

We may invest in preferred securities or other securities the U.S. federal income tax treatment of which may not be clear or may be subject to recharacterization by the IRS. To the extent the tax treatment of such securities or the income from such securities differs from the expected tax treatment, it could affect the timing or character of income recognized, requiring us to purchase or sell securities, or otherwise change our portfolio, in order to comply with the tax rules applicable to RICs under the Code.

We may distribute taxable dividends that are payable in cash or shares of our common stock at the election of each stockholder. Under certain applicable provisions of the Code and the Treasury regulations, distributions payable in cash or in shares of stock at the election of stockholders are treated as taxable dividends. The Internal Revenue Service has issued private rulings 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. Under these rulings, 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. If we decide to make any distributions consistent with these rulings that are payable in part in our 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 ordinary income (or as 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 United States 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.

Taxation of U.S. Stockholders

Whether an investment in shares of our common stock is appropriate for a U.S. stockholder will depend upon that person’s particular circumstances. An investment in shares of our common stock by a U.S. stockholder may have adverse tax consequences. The following summary generally describes certain U.S. federal income tax consequences of an investment in shares of our common stock by taxable U.S. stockholders and not by U.S. stockholders that are generally exempt from U.S. federal income taxation. U.S. stockholders should consult their own tax advisors before making an investment in our common stock.

##### Table of Contents

Distributions by us generally are taxable to U.S. stockholders as ordinary income or capital gain. Distributions of our “investment company taxable income” (which is, generally, our ordinary income excluding net capital gain) will be taxable as ordinary income to U.S. stockholders to the extent of our current or accumulated earnings and profits, whether paid in cash or reinvested in additional common stock. To the extent such distributions paid by us to noncorporate U.S. stockholders (including individuals) are attributable to dividends from U.S. corporations and certain qualified foreign corporations, such distributions generally will be eligible for taxation at rates applicable to “qualifying dividends” (at a maximum tax rate of 15% through 2012) provided that we properly report such distribution as “qualified dividend income” in a written statement furnished to our stockholders and certain holding period and other requirements are satisfied. In this regard, it is not anticipated that a significant portion of distributions paid by us will be attributable to qualifying dividends; therefore, our distributions generally will not qualify for the preferential rates applicable to qualified dividend income. Distributions of our net capital gain (which is generally our net long-term capital gain in excess of net short-term capital loss) properly designated by us as “capital gain dividends” will be taxable to a U.S. stockholder as long-term capital gain (at a maximum rate of 15% through 2012 in the case of individuals, trusts or estates), regardless of the U.S. stockholder’s holding period for his, her or its common stock and regardless of whether paid in cash or reinvested in additional common stock. Distributions in excess of our current and accumulated earnings and profits first will reduce a U.S. stockholder’s adjusted tax basis in such stockholder’s common stock and, after the adjusted basis is reduced to zero, will constitute capital gain to such U.S. stockholder.

Although we currently intend to distribute any long-term capital gain at least annually, we may in the future decide to retain some or all of our long-term capital gain, but designate the retained amount as a “deemed distribution.” In that case, among other consequences, we will pay tax on the retained amount, each U.S. stockholder will be required to include his, her or its proportionate share of the deemed distribution in income as if it had been actually distributed to the U.S. stockholder, and the U.S. stockholder will be entitled to claim a credit equal to his, her or its allocable share of the tax paid thereon by us. The amount of the deemed distribution net of such tax will be added to the U.S. stockholder’s tax basis for his, her or its common stock. Since we expect to pay tax on any retained capital gain at our regular corporate tax rate, and since that rate is in excess of the maximum rate currently payable by individuals on net capital gain, the amount of tax that individual stockholders will be treated as having paid and for which they will receive a credit will exceed the tax they owe on the retained net capital gain. Such excess generally may be claimed as a credit against the U.S. stockholder’s other U.S. federal income tax obligations or may be refunded to the extent it exceeds a stockholder’s liability for U.S. federal income tax. A stockholder that is not subject to U.S. federal income tax or otherwise required to file a U.S. federal income tax return would be required to file a U.S. federal income tax return on the appropriate form in order to claim a refund for the taxes we paid. In order to utilize the deemed distribution approach, we must provide written notice to our stockholders prior to the expiration of 60 days after the close of the relevant taxable year. We cannot treat any of our investment company taxable income as a “deemed distribution.”

We could be subject to the alternative minimum tax, or the AMT, but any items that are treated differently for AMT purposes must be apportioned between us and our stockholders and this may affect U.S. stockholders’ AMT liabilities. Although regulations explaining the precise method of apportionment have not yet been issued, such items will generally be apportioned in the same proportion that distributions paid to each stockholder bear to our taxable income (determined without regard to the dividends paid deduction), unless a different method for a particular item is warranted under the circumstances.

For purposes of determining (1) whether the Annual Distribution Requirement is satisfied for any year and (2) the amount of capital gain dividends paid for that year, we may, under certain circumstances, elect to treat a dividend that is paid during the following taxable year as if it had been paid during the taxable year in question. If we make such an election, the U.S. stockholder will still be treated as receiving the dividend in the taxable year in which the distribution is made. However, any dividend declared by us in October, November or December of any calendar year, payable to stockholders of record on a specified date in any such month and actually paid during January of the following year, will be treated as if it had been received by our U.S. stockholders on December 31 of the year in which the dividend was declared.

If an investor purchases shares of our common stock shortly before the record date of a distribution, the price of the shares will include the value of the distribution, and the investor will be subject to tax on the distribution even though it represents a return of his, her or its investment.

A U.S. stockholder generally will recognize taxable gain or loss if the stockholder sells or otherwise disposes of his, her or its shares of our common stock. The amount of gain or loss will be measured by the difference between such stockholder’s adjusted tax basis in the common stock sold and the amount of the proceeds received in exchange. Any gain arising from such sale or disposition generally will be treated as long-term capital gain or loss if the stockholder has held his, her or its shares for more than one year. Otherwise, it will be classified as short-term capital gain or loss. However, any capital loss arising from the sale or disposition of shares of our common stock held for six months or less will be treated as long-term capital loss to the extent of the amount of capital gain dividends received, or undistributed capital gain deemed received, with respect to such shares. In addition, all or a portion of any loss recognized upon a disposition of shares of our common stock may be disallowed if other substantially identical shares are purchased (whether through reinvestment of distributions or otherwise) within 30 days before or after the disposition. The ability to otherwise deduct capital loss may be subject to other limitations under the Code.

In general, noncorporate U.S. stockholders, including individuals, trusts and estates, are subject to U.S. federal income tax (at a maximum rate of 15% through 2012) on their net capital gain, or the excess of realized net long-term capital gain over realized net short-term capital loss for a taxable year, including a long-term capital gain derived from an investment in our shares. Such rate is lower than the maximum rate on ordinary income currently payable by individuals. Corporate U.S. stockholders currently are subject to U.S. federal income tax on net capital gain at the maximum 35% rate also applied to ordinary income. Noncorporate stockholders with net capital loss for a year (which we define as capital loss in excess of capital gain) generally may deduct up to $3,000 of such losses against their ordinary income each year; any net capital loss of a noncorporate stockholder in excess of $3,000 generally may be carried forward and used in subsequent years as provided in the Code. Corporate stockholders generally may not deduct any net capital loss for a year, but may carry back such losses for three years or carry forward such losses for five years.

For taxable years beginning after December 31, 2012, certain U.S. stockholders who are individuals, estates or trusts generally will be subject to a 3.8% Medicare tax on, among other things, dividends on, and capital gain from the sale or other disposition of our common stock.

A “publicly offered regulated investment company” is a regulated investment company whose shares are either (i) continuously offered pursuant to a public offering, (ii) regularly traded on an established securities market or (iii) held by at least 500 persons at all times during the taxable year. If we are not a publicly offered regulated investment company for any period, a non-corporate shareholder’s pro rata portion of our affected expenses, including our management fees, will be treated as an additional dividend to the shareholder and will be deductible by such shareholder only to the extent permitted under the limitations described below. For non-corporate shareholders, including individuals, trusts, and estates, significant limitations generally apply to the deductibility of certain expenses of a nonpublicly offered regulated investment company, including advisory fees. In particular, these expenses, referred to as miscellaneous itemized deductions, are deductible only to individuals to the extent they exceed 2% of such a shareholder’s adjusted gross income, and are not deductible for AMT purposes. Because we anticipate that shares of our common stock will continue to be regularly traded on an established securities market, we believe that we will continue to qualify as a “publicly offered regulated investment company.”

We will send to each of our U.S. stockholders, as promptly as possible after the end of each calendar year, a written statement detailing, on a per share and per distribution basis, the amounts includible in such U.S. stockholder’s taxable income for such year as ordinary income and as long-term capital gain. In addition, the U.S. federal tax status of each year’s distributions generally will be reported to the IRS (including the amount of dividends, if any, eligible for the current 15% maximum rate). Distributions paid by us generally will not be eligible for the dividends-received deduction or the preferential tax rate applicable to qualifying dividends. Distributions may also be subject to additional state, local and foreign taxes depending on a U.S. stockholder’s particular situation.

We may be required to withhold U.S. federal income tax, or backup withholding (at a rate of 28% through 2012), from all taxable distributions to any noncorporate U.S. stockholder (1) who fails to furnish us with a correct taxpayer identification number or a certificate that such stockholder is exempt from backup withholding or (2) with respect to whom the IRS notifies us that such stockholder has failed to properly report certain interest and dividend income to the IRS and to respond to notices to that effect. An individual’s taxpayer identification number is his or her social security number. Backup withholding tax is not an additional tax, and any amount withheld may be refunded or credited against the U.S. stockholder’s U.S. federal income tax liability, provided that proper information is timely provided to the IRS.

For taxable years beginning after December 31, 2013, if certain disclosure requirements related to U.S. accounts or ownership are not satisfied, a U.S. federal withholding tax at a 30% rate will be imposed on dividends received by U.S. stockholders that own their stock through foreign accounts or foreign intermediaries. In addition, for taxable years beginning after December 31, 2014, if certain disclosure requirements related to U.S. accounts or ownership are not satisfied, a U.S. federal withholding tax at a 30% rate will be imposed on proceeds of sale in respect of our stock received by U.S. stockholders that own their stock through foreign accounts or foreign intermediaries. We will not pay any additional amounts in respect of any amounts withheld.

Under U.S. Treasury regulations, if a stockholder recognizes a loss with respect to shares of our stock of $2 million or more for a noncorporate stockholder or $10 million or more for a corporate stockholder in any single taxable year (or a greater loss over a combination of years), the stockholder must file with the IRS a disclosure statement on IRS Form 8886 (or successor form). Direct stockholders of portfolio securities in many cases are excepted from this reporting requirement, but under current guidance, stockholders of a RIC are not excepted. Future guidance may extend the current exception from this reporting requirement to stockholders of most or all RICs. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Significant monetary penalties apply to a failure to comply with this reporting requirement. States may also have a similar reporting requirement. Stockholders should consult their own tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Taxation of Non-U.S. Stockholders

Whether an investment in the shares is appropriate for a Non-U.S. stockholder will depend upon that person’s particular circumstances. An investment in the shares by a Non-U.S. stockholder may have adverse tax consequences. Non-U.S. stockholders should consult their tax advisers before investing in our common stock.

Distributions of our “investment company taxable income” to Non-U.S. stockholders that are not “effectively connected” with a U.S. trade or business carried on by the Non-U.S. stockholder, will generally be subject to withholding of U.S. federal income tax at a rate of 30% (or lower rate provided by an applicable treaty) to the extent of our current and accumulated earnings and profits, unless an applicable exception applies. For taxable years beginning before 2012, however, we generally will not be required to withhold any amounts with respect to distributions of (i) U.S.-source interest income that would not have been subject to withholding of U.S. federal income tax if they had been earned directly by a Non-U.S. stockholder, and (ii) net short-term capital gains in excess of net long-term capital losses that would not have been subject to withholding of U.S. federal income tax if they had been earned directly by a Non-U.S. stockholder, in each case only to the extent that such distributions are properly reported by us as “interest-related dividends” or “short-term capital gain dividends,” as the case may be, and certain other requirements are met.

Actual or deemed distributions of our net capital gain to a Non-U.S. stockholder, and gain realized by a Non-U.S. stockholder upon the sale of our common stock, that are not effectively connected with a U.S. trade or business carried on by the Non-U.S. stockholder, will generally not be subject to U.S. federal withholding tax and generally will not be subject to U.S. federal income tax unless the Non-U.S. stockholder is a nonresident alien individual and is physically present in the United States for more than 182 days during the taxable year and

161

##### Table of Contents

meets certain other requirements. However, withholding of U.S. federal income tax at a rate of 30% on capital gain of nonresident alien individuals who are physically present in the United States for more than the 182 day period only applies in exceptional cases because any individual present in the United States for more than 182 days during the taxable year is generally treated as a resident for U.S. income tax purposes; in that case, he or she would be subject to U.S. income tax on his or her worldwide income at the graduated rates applicable to U.S. citizens, rather than the 30% U.S. federal withholding tax.

If we distribute our net capital gain in the form of deemed rather than actual distributions (which we may do in the future), a Non-U.S. stockholder will be entitled to a U.S. federal income tax credit or tax refund equal to the stockholder’s allocable share of the tax we pay on the capital gain deemed to have been distributed. In order to obtain the refund, the Non-U.S. stockholder must obtain a U.S. taxpayer identification number and file a U.S. federal income tax return even if the Non-U.S. stockholder would not otherwise be required to obtain a U.S. taxpayer identification number or file a U.S. federal income tax return. Accordingly, investment in the shares may not be appropriate for a Non-U.S. stockholder.

Distributions of our “investment company taxable income” and net capital gain (including deemed distributions) to Non-U.S. stockholders, and gain realized by Non-U.S. stockholders upon the sale of our common stock that is “effectively connected” with a U.S. trade or business carried on by the Non-U.S. stockholder (or if an income tax treaty applies, attributable to a “permanent establishment” in the United States), will be subject to U.S. federal income tax at the graduated rates applicable to U.S. citizens, residents and domestic corporations. Corporate Non-U.S. stockholders may also be subject to an additional branch profits tax at a rate of 30% imposed by the Code (or lower rate provided by an applicable treaty). In the case of a non-corporate Non-U.S. stockholder, we may be required to withhold U.S. federal income tax from distributions that are otherwise exempt from withholding tax (or taxable at a reduced rate) unless the Non-U.S. stockholder certifies his or her foreign status under penalties of perjury or otherwise establishes an exemption.

The tax consequences to a Non-U.S. stockholder entitled to claim the benefits of an applicable tax treaty may differ from those described herein. Non-U.S. stockholders are advised to consult their own tax advisers with respect to the particular tax consequences to them of an investment in our shares.

A Non-U.S. stockholder who is a nonresident alien individual may be subject to information reporting and backup withholding of U.S. federal income tax on dividends unless the Non-U.S. stockholder provides us or the dividend paying agent with an IRS Form W-8BEN (or an acceptable substitute form) or otherwise meets documentary evidence requirements for establishing that it is a Non-U.S. stockholder or otherwise establishes an exemption from backup withholding.

For taxable years beginning after December 31, 2013, if certain disclosure requirements related to U.S. accounts or ownership are not satisfied, a U.S. federal withholding tax at a 30% rate will be imposed on dividends received by certain Non-U.S. stockholders. In addition, for taxable years beginning after December 31, 2014, if certain disclosure requirements related to U.S. accounts or ownership are not satisfied, a U.S. federal withholding tax at a 30% rate will be imposed on proceeds of sale in respect of our stock received by certain Non-U.S. stockholders. If payment of withholding taxes is required, Non-U.S. stockholders that are otherwise eligible for an exemption from, or reduction of, U.S. federal withholding taxes with respect to such dividends and proceeds will be required to seek a refund from the IRS to obtain the benefit of such exemption or reduction. We will not pay any additional amounts in respect of any amounts withheld.

Non-U.S. persons should consult their own tax advisors with respect to the U.S. federal income tax and withholding tax, and state, local and foreign tax consequences of an investment in the shares.

Failure To Obtain RIC Tax Treatment

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 obtain tax treatment as a RIC, 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. Distributions would generally be taxable to our stockholders as dividend income to the extent of our current and accumulated earnings and profits (in the case of noncorporate U.S. stockholders, at a maximum rate applicable to qualified dividend income of 15% through 2012). Subject to certain limitations under the Code, corporate distributees would be eligible for the dividends-received deduction. 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.

If we fail to meet the RIC requirements for more than two consecutive years and then, seek to re-qualify as a RIC, we would be subject to corporate-level taxation on any built-in gain recognized during the succeeding 10-year period unless we made a special election to recognize all such built-in gain upon our re-qualification as a RIC and to pay the corporate-level tax on such built-in gain.

Sunset of Reduced Tax Rate Provisions

Certain tax laws providing for certain reduced tax rates described herein are subject to sunset provisions. The sunset provisions generally provide that for taxable years beginning after December 31, 2012, certain provisions that are currently in the Code will revert back to a prior version of those provisions. Such provisions include those related to the reduced maximum income tax rates generally applicable to ordinary income, long-term capital gain and qualified dividend income recognized by certain noncorporate taxpayers and certain other tax rate provisions described herein. The impact of this reversion is not discussed herein. Consequently, prospective stockholders should consult their own tax advisors regarding the effect of these sunset provisions on an investment in our common stock.

Possible Legislative or Other Actions Affecting Tax Considerations

Prospective investors should recognize that the present U.S. federal income tax treatment of an investment in our stock may be modified by legislative, judicial or administrative action at any time, and that any such action may affect investments and commitments previously made. The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process any by the IRS and the U.S. Treasury Department, resulting in revisions of regulations and revised interpretations of established concepts as well as statutory changes. Revisions in U.S. federal tax laws and interpretations thereof could adversely affect the tax consequences of an investment in our stock.

The discussion set forth herein does not constitute tax advice, and potential investors should consult their own tax advisors concerning the tax considerations relevant to their particular situation.

REGULATION

We, and Triangle SBIC, have elected to be treated 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 directors 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.

163

##### Table of Contents

The 1940 Act defines “a majority of the outstanding voting securities” as the lesser of (i) 67.0% or more of the voting securities present at a meeting if the holders of more than 50.0% of our outstanding voting securities are present or represented by proxy, or (ii) 50.0% of our 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 70.0% of the company’s total assets. The principal categories of qualifying assets relevant to our business are any of the following:

(1) 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, 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. An eligible portfolio company is defined in the 1940 Act and rules adopted pursuant thereto, as any issuer which:

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

(b) is not an investment company (other than an SBIC wholly owned by the BDC) or a company that would be an investment company but for exclusions under the 1940 Act for certain financial companies such as banks, brokers, commercial finance companies, mortgage companies and insurance companies; and

(c) satisfies any of the following:

(i) does not have any class of securities with respect to which a broker or dealer may extend margin credit;

(ii) 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;

(iii) is a small and solvent company having total assets of not more than $4.0 million and capital and surplus of not less than $2.0 million;

(iv) does not have any class of securities listed on a national securities exchange; or

(v) has a class of securities listed on a national securities exchange, but has an aggregate value of outstanding voting and non-voting common equity of less than $250.0 million.

(2) Securities in companies that were eligible portfolio companies when we made our initial investment if certain other requirements are satisfied.

(3) Securities of any eligible portfolio company that we control.

(4) 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).

(5) 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 60.0% of the outstanding equity of the eligible portfolio company.

164

##### Table of Contents

(6) Securities received in exchange for or distributed on or with respect to securities described in (1) through (5) above, or pursuant to the exercise of warrants or rights relating to such securities.

(7) 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), (3) or (4) above.

Managerial Assistance to Portfolio Companies

In order to count portfolio securities as qualifying assets for the purpose of the 70.0% test, we must either control the issuer of the securities or must offer to make available to the 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 “significant managerial assistance” means, among other things, any arrangement whereby we, through our directors, officers or employees, offer to provide, and, if accepted, do so provide, significant guidance and counsel concerning the management, operations or business objectives and policies of a portfolio company.

Temporary Investments

Pending investment in other types of “qualifying assets,” as described above, our investments may consist of cash, cash equivalents, U.S. government securities or high-quality debt securities maturing in one year or less from the time of investment, which we refer to, collectively, as temporary investments, so that 70.0% of our assets are qualifying assets. We may invest in U.S. Treasury bills or in repurchase agreements, provided that such agreements are fully collateralized by cash or securities issued by the U.S. Government or its agencies. A repurchase agreement involves the purchase by an investor, such as us, of a specified security and the simultaneous agreement by the seller to repurchase it at an agreed-upon future date and at a price that is greater than the purchase price by an amount that reflects an agreed-upon interest rate. There is no percentage restriction on the proportion of our assets that may be invested in such repurchase agreements. However, if more than 25.0% of our total assets constitute repurchase agreements from a single counterparty, we would not meet the Diversification Tests in order to qualify as a RIC for federal income tax purposes. Thus, we do not intend to enter into repurchase agreements with a single counterparty in excess of this limit. Our management team will monitor the creditworthiness of the counterparties with which we enter into repurchase agreement transactions.

Senior Securities

We are permitted, under specified conditions, to issue multiple classes of debt and one class of stock senior to our common stock if our asset coverage, as defined in the 1940 Act, is at least equal to 200.0% immediately after each such issuance. In addition, while any senior securities remain outstanding, 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 5.0% 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 — 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.”

Code of Business Conduct and Ethics and Corporate Governance Guidelines

We have adopted, pursuant to Rule 17j-1 of the 1940 Act, a code of ethics, which we call our “Code of Business Conduct and Ethics” and corporate governance guidelines, which collectively covers ethics and business conduct. These documents apply to our directors, officers and employees, establish procedures for personal investments and restrict certain personal securities transactions. Personnel subject to these code of ethics 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 certain requirements. Our Code of Business Conduct and Ethics and corporate governance guidelines are available on the Investor Relations section of our website at the following URL: http://ir.tcap.com/governance.cfm. You may read and copy the code of ethics at the SEC’s Public Reference Room in Washington, D.C. You may obtain information on the operation of the Public Reference Room by calling the SEC at (202) 942-8090. In addition, the code of ethics is attached as an exhibit to our annual report on Form 10-K and is available on the EDGAR Database on the SEC’s Internet site at www.sec.gov. You may also obtain a copy of our code of ethics, after paying a duplicating fee, by electronic request at the following URL: publicinfo@sec.gov, or by writing the SEC’s Public Reference Section, 100 F Street, N.E., Washington, D.C. 20549. We will report any material amendments to or waivers of a required provision of our Code of Business Conduct and Ethics and corporate governance guidelines on our website or in a Current Report on Form 8-K.

Proxy Voting Policies and Procedures

We vote proxies relating to our portfolio securities in a manner which we believe will be in 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 may 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 professionals who are responsible for monitoring each of our investments. To ensure that our vote is not the product of a conflict of interest, we require that: (i) anyone involved in the decision making process disclose to our chief compliance officer any potential conflict that he or she is aware of and any contact that he or she has had with any interested party regarding a proxy vote; and (ii) employees involved in the decision making process or vote administration are prohibited from revealing how we intend to vote on a proposal in order to reduce any attempted influence from interested parties.

Stockholders may, without charge, obtain information regarding how we voted proxies with respect to our portfolio securities by making a written request for proxy voting information to: Chief Compliance Officer, 3700 Glenwood Avenue, Suite 530, Raleigh, North Carolina 27612.

Other

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

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 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.

Small Business Administration Regulations

Triangle SBIC and Triangle SBIC II, our wholly-owned subsidiaries, are each licensed by the SBA to operate as a Small Business Investment Company under Section 301(c) of the Small Business Investment Act of 1958. Triangle SBIC’s license to operate as an SBIC became effective on September 11, 2003 and Triangle SBIC II’s license to operate as an SBIC became effective on May 26, 2010.

SBICs are designed to stimulate the flow of private equity capital to eligible small businesses. Under SBA 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. Triangle SBIC and Triangle SBIC II have typically invested in senior and subordinated debt, acquired warrants and/or made equity investments in qualifying small businesses.

Under current SBA regulations, eligible small businesses generally include businesses that (together with their affiliates) have a tangible net worth not exceeding $18.0 million and have average annual net income after federal income taxes not exceeding $6.0 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 between 20.0% and 25.0% of its investment activity to “smaller” concerns as defined by the SBA. The exact percentage depends upon, among other factors, the date that the SBIC was licensed, when it obtained leverage commitments, the amount of leverage drawn and when financings occur. A smaller concern generally includes businesses that have a tangible net worth not exceeding $6.0 million and have average annual net income after U.S. federal income taxes not exceeding $2.0 million (average net income to be computed without benefit of any net carryover loss) for the two most recent fiscal years. SBA regulations also provide alternative size standard criteria to determine eligibility for designation as an eligible small business or smaller concern, which criteria depend on the industry in which the business is primarily engaged and are based on either the number of employees or annual receipts. However, once an SBIC has invested in a company, it 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, project financing and investment outside the United States, to businesses engaged in a few 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 30.0% of the SBIC’s regulatory capital in any one portfolio company.

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). Although prior regulations prohibited an SBIC from controlling a small business concern except in limited circumstances, regulations adopted by the SBA in 2002 now 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 10.0% or more of a class of capital stock of a licensed SBIC. A “change of control” is any event which would result in the transfer of the power, direct or indirect, to direct the management and policies of an SBIC, whether through ownership, contractual arrangements or otherwise.

An SBIC (or group of SBICs under common control) may generally have outstanding debentures guaranteed by the SBA in amounts up to two times (and in certain cases, up to three times) the amount of the regulatory capital of the SBIC(s). Debentures guaranteed by the SBA have a maturity of ten years, require semi-annual payments of interest, do not require any principal payments prior to maturity, and, historically, were subject to certain prepayment penalties. Those prepayment penalties no longer apply as of September 2006. As of

167

##### Table of Contents

March 31, 2012, the maximum statutory limit on the dollar amount of outstanding SBA-guaranteed debentures that may be issued by a single SBIC was $150.0 million and $225.0 million for a group of SBICs under common control. As of March 31, 2012, Triangle SBIC has issued $139.6 million of SBA guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of March 31, 2012, Triangle SBIC II has issued $75.0 million in face amount of SBA guaranteed debentures. If an SBIC invests in smaller concerns located in low-income geographic areas, these limits can be increased. The weighted average interest rate for all SBA guaranteed debentures as of March 31, 2012 was 4.76%. As of March 31, 2012, all SBA debentures have been pooled.

SBICs must invest idle funds that are not being used to make loans in investments permitted under SBA 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 as to principal and interest by, the United States 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 forms with the SBA. Triangle SBIC was audited by the SBA during 2010, and no regulatory violations were disclosed as a result of the audit.

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 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, 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 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 such report must be audited separately, by our independent registered public accounting firm; 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 without regard to significant deficiencies and material weaknesses.

The Sarbanes-Oxley Act requires us to review our current policies and procedures to determine whether we comply with the Sarbanes-Oxley Act and the regulations promulgated thereunder. We monitor our compliance with all regulations that are adopted under the Sarbanes-Oxley Act and will take all actions necessary to ensure that we are in compliance therewith.

PLAN OF DISTRIBUTION

We may sell our securities through underwriters or dealers, directly to one or more purchasers or through agents or through a combination of any such methods of sale. Any underwriter or agent involved in the offer and sale of our securities will also be named in the applicable prospectus supplement.

The distribution of our securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at prevailing market prices at the time of sale, at prices related to such prevailing market prices, or at negotiated prices, provided, however, that the offering price per share of our securities less any underwriting commissions or discounts must equal or exceed the net asset value per share of our securities except that we may sell shares of our securities at a price below net asset value per share if a majority of the number of beneficial holders of our stock have approved such a sale or if the following conditions are met: (i) holders of a majority of our stock and a majority of our stock not held by affiliated persons have approved issuance at less than net asset value per share during the one year period prior to such sale; (ii) a majority of our directors who have no financial interest in the sale and a majority of such directors who are not interested persons of us have determined that such sale would be in our best interest and in the best interests of our stockholders; and (iii) a majority of our directors who have no financial interest in the sale and a majority of such directors who are not interested persons of us, in consultation with the underwriter or underwriters of the offering if it is to be underwritten, have determined in good faith, and as of a time immediately prior to the first solicitation by or on behalf of us of firm commitments to purchase such securities or immediately prior to the issuance of such securities, that the price at which such securities are to be sold is not less than a price which closely approximates the market value of those securities, less any distributing commission or discount.

On May 2, 2012, our common stockholders voted to allow us to issue common stock at a price below net asset value per share for a period of one year ending on the earlier of May 2, 2013 or the date of our 2013 Annual Meeting of Stockholders. Our stockholders did not specify a maximum discount below net asset value at which we are able to issue our common stock; however, we do not intend to issue shares of our common stock below net asset value unless our Board of Directors determines that it would be in our stockholders’ best interests to do so.

In connection with the sale of our securities, underwriters or agents may receive compensation from us or from purchasers of our securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell our securities to or through dealers and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of our securities may be deemed to be underwriters under the Securities Act, and any discounts and commissions they receive from us and any profit realized by them on the resale of our securities may be deemed to be underwriting discounts and commissions under the Securities Act. Any such underwriter or agent will be identified and any such compensation received from us will be described in the applicable prospectus supplement.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in such sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment).

Any of our common stock sold pursuant to a prospectus supplement will be listed on the NYSE, or another exchange on which our common stock is traded.

170

##### Table of Contents

Under agreements into which we may enter, underwriters, dealers and agents who participate in the distribution of our securities may be entitled to indemnification by us against certain liabilities, including liabilities under the Securities Act. Underwriters, dealers and agents may engage in transactions with, or perform services for, us in the ordinary course of business.

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase our securities from us pursuant to contracts providing for payment and delivery on a future date. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases such institutions must be approved by us. The obligations of any purchaser under any such contract will be subject to the condition that the purchase of our securities shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts. Such contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

In order to comply with the securities laws of certain states, if applicable, our securities offered hereby will be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states, our securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

The maximum commission or discount to be received by any member of the Financial Industry Regulatory Authority, Inc. will not be greater than 10.0% for the sale of any securities being registered.

CUSTODIAN, TRANSFER AND DIVIDEND PAYING AGENT AND REGISTRAR

Our securities are held under custody agreements by U.S. Bank National Association, Branch Banking and Trust Company and Fifth Third Bank. The addresses of the custodians are: U.S. Bank National Association, Attn: Institutional Trust & Custody, 214 North Tryon Street; 27th floor, Charlotte, NC 28202; Branch Banking and Trust Company, Attn: Mortgage Custody Department of Corporate Trust Services, 5130 Parkway Plaza Boulevard, Charlotte, NC 28217; and Fifth Third Bank, Attn: Custody Services, 201 North Tyson Street, Ste. 1800, Charlotte, NC 28202. Computershare Limited acts as our transfer agent, dividend paying agent and registrar of our common stock. The principal business address of our transfer agent, dividend paying agent and registrar is Computershare Limited, Shareowner Services, PO Box 358035, Pittsburgh, PA, 15252-8035, telephone number: (866) 228-7201.

BROKERAGE ALLOCATION AND OTHER PRACTICES

We did not pay any brokerage commissions during the years ended December 31, 2011, 2010 or 2009 in connection with the acquisition and/or disposal of our investments. We generally acquire and dispose of our investments in privately negotiated transactions; therefore, we infrequently use brokers in the normal course of our business. Our management team is primarily responsible for the execution of any publicly traded securities portion of our portfolio transactions and the allocation of brokerage commissions. We do not expect to execute transactions through any particular broker or dealer, but will seek to obtain the best net results for us, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, and operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While we will generally seek reasonably competitive trade execution costs, we will not necessarily pay the lowest spread or commission available. Subject to applicable legal requirements, we may select a broker based partly upon brokerage or research services provided to us. In return for such services, we may pay a higher commission than other brokers would charge if we determine in good faith that such commission is reasonable in relation to the services provided.

Notes to Unaudited Consolidated Financial Statements

1. | ORGANIZATION, BASIS OF PRESENTATION AND BUSINESS

Organization

Triangle Capital Corporation and its wholly owned subsidiaries, including Triangle Mezzanine Fund LLLP ( “Triangle SBIC”) and Triangle Mezzanine Fund II LP (“Triangle SBIC II”) (collectively, the “Company”), operates as a Business Development Company (“BDC”) under the Investment Company Act of 1940 (the “1940 Act”). Triangle SBIC and Triangle SBIC II are specialty finance limited partnerships formed to make investments primarily in middle market companies located throughout the United States. On September 11, 2003, Triangle SBIC was licensed to operate as a Small Business Investment Company (“SBIC”) under the authority of the United States Small Business Administration (“SBA”). On May 26, 2010, Triangle SBIC II obtained its license to operate as an SBIC. As SBICs, both Triangle SBIC and Triangle SBIC II are subject to a variety of regulations concerning, among other things, the size and nature of the companies in which they may invest and the structure of those investments.

The Company currently operates as a closed–end, non–diversified investment company and has elected to be treated as a BDC under the 1940 Act. The Company is internally managed by its executive officers under the supervision of its Board of Directors. The Company does not pay management or advisory fees, but instead incurs the operating costs associated with employing executive management and investment and portfolio management professionals.

Basis of Presentation

The financial statements of the Company include the accounts of the Company and its wholly-owned subsidiaries, including Triangle SBIC and Triangle SBIC II. Neither Triangle SBIC nor Triangle SBIC II consolidates portfolio company investments. The effects of all intercompany transactions between the Company and its subsidiaries have been eliminated in consolidation.

The accompanying unaudited financial statements are presented in conformity with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for the fair presentation of financial statements for the interim period, have been reflected in the unaudited consolidated financial statements. The current period’s results of operations are not necessarily indicative of results that ultimately may be achieved for the year. Additionally, the unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes thereto for the period ended December 31, 2011. Financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the amounts and disclosures reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

Recently Issued Accounting Standards

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, or ASU 2011-04. ASU 2011-04 clarifies the application of existing fair value measurement and disclosure requirements, changes the application of some requirements for measuring fair value and requires additional disclosure for fair value measurements categorized in Level 3 of the fair value hierarchy. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. The Company adopted this standard on January 1, 2012. The adoption of ASU 2011-04 did not have a material impact on the Company’s process for measuring fair values or on its financial statements, other than the inclusion of additional required disclosures.

Notes to Unaudited Consolidated Financial Statements — (Continued)

Reclassifications

Certain reclassifications have been made in the consolidated financial statements for the quarter ended March 31, 2011 in order to conform to current presentation. The Company had historically included losses realized on the extinguishment of debt in “Amortization of deferred financing fees” in the Consolidated Statements of Operations. Effective January 1, 2012, the Company records losses on the extinguishment of debt as a separate line item in the Consolidated Statements of Operations. See Note 4 to the Consolidated Financial Statements for further discussion of deferred financing fees.

2. | INVESTMENTS

The Company primarily invests in subordinated debt (or 2 nd lien notes) of privately held companies. These subordinated debt investments generally are secured by a second priority security interest in the assets of the borrower. In addition, the Company generally invests in an equity instrument of the borrower, such as warrants to purchase common stock in the portfolio company or direct preferred or common equity interests. The Company also invests in senior debt (or 1 st lien notes) on a more limited basis.

The cost basis of our debt investments include any unamortized original issue discount, unamortized loan origination fees and payment–in–kind (“PIK”) interest, if any. Summaries of the composition of the Company’s investment portfolio at cost and fair value, and as a percentage of total investments, are shown in the following tables:

Under ASC Topic 820, a financial

instrument is categorized within the ASC Topic 820 valuation hierarchy based upon the lowest level of input to the valuation process that is significant to the fair value measurement. The three levels of valuation inputs established by ASC Topic 820 are as follows:

Level 1 Inputs — quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 Inputs — include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 Inputs — include inputs that are unobservable and significant to the fair value measurement.

The Company’s investment portfolio is comprised of debt and equity instruments of privately held companies for which quoted prices or other inputs falling within the categories of Level 1 and Level 2 are not available. Therefore, the Company determines the fair value of its investments in good faith using level 3 inputs, pursuant to a valuation policy and process that is established by the management of the Company with the assistance of certain third-party advisors and subsequently approved by the Company’s Board of Directors. There is no single standard for determining fair value in good faith, as fair value depends upon the specific circumstances of each individual investment. The recorded fair values of the Company’s investments may differ significantly from fair values that would have been used had an active market for the securities existed. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned.

The Company’s valuation process is led by the Company’s executive officers and managing directors. The Company’s valuation process begins with a quarterly review of each investment in the Company’s investment portfolio by the Company’s executive officers and investment committee. Valuations of each portfolio security are then prepared by the Company’s investment professionals, who have direct responsibility for the origination, management and monitoring of each investment. Under the Company’s valuation policy, each investment valuation is subject to (i) a review by the lead investment officer responsible for the portfolio company investment and (ii) a peer review by a second investment officer or executive officer of the Company. Generally, any investment that is valued below cost is subjected to review by one of the Company’s executive officers. After the peer review is complete, the Company engages Duff & Phelps, LLC (“Duff & Phelps”), an independent valuation firm, to provide a third-party review of certain investments, as described further below. In addition, all investment valuations are provided to the Company’s independent registered public accounting firm each quarter in connection with quarterly review procedures and the annual audit of our financial statements. Finally, the Board of Directors has the responsibility for reviewing and approving, in good faith, the fair value of the Company’s investments in accordance with the 1940 Act.

Duff & Phelps provides third party valuation consulting services to the Company which consist of certain limited procedures that the Company identified and requested Duff & Phelps to perform (hereinafter referred to as the “procedures”). The Company generally requests Duff & Phelps to perform the procedures on each portfolio company at least once in every calendar year and for new portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In addition, the Company generally requests Duff & Phelps to perform the procedures on a portfolio company when there has been a significant change in the fair value of the investment. In certain instances, the Company may determine that it is not cost-effective, and as a result is not in the Company’s stockholders’ best interest, to request Duff & Phelps to perform the procedures on one or more portfolio companies. Such instances include, but are not limited to, situations where the fair value of the investment in the portfolio company is determined to be insignificant relative to the total investment portfolio.

The total number of investments and the percentage of the investment portfolio on which the Company asked Duff & Phelps to perform such procedures are summarized below by period:

For the quarter ended: |  | Total companies |  |  | Percent of total investments at fair value(1) |
March 31, 2011 |  |  | 11 |  |  |  | 34 | %
June 30, 2011 |  |  | 13 |  |  |  | 26 | %
September 30, 2011 |  |  | 11 |  |  |  | 31 | %
December 31, 2011 |  |  | 12 |  |  |  | 22 | %
March 31, 2012 |  |  | 10 |  |  |  | 19 | %

| (1) | Exclusive of the fair value of new investments made during the quarter

Upon completion of the procedures, Duff & Phelps concluded that the fair value of those investments subjected to the procedures appeared reasonable. The Company’s Board of Directors is ultimately responsible for determining the fair value of the Company’s investments in good faith.

Investment Valuation Inputs

Under ASC Topic 820, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For the Company’s portfolio securities, fair value is generally the amount that the Company might reasonably expect to receive upon the current sale of the security. Under ASC Topic 820, the fair value measurement assumes that the sale occurs in the principal market for the security, or in the absence of a principal market, in the most advantageous market for the security. Under ASC Topic 820, if no market for the security exists or if the Company does not have access to the principal market, the security should be valued based on the sale occurring in a hypothetical market. The securities in which the Company invests are generally only purchased and sold in merger and acquisition transactions, in which case the entire portfolio company is sold to a third-party purchaser. As a result, unless the Company has the ability to control such a transaction, the assumed principal market for the Company’s securities is a hypothetical secondary market. The level 3 inputs to the Company’s valuation process reflect the Company’s best estimate of the assumptions that would be used by market participants in pricing the investment in a transaction in a hypothetical secondary market.

Enterprise Value Waterfall Approach

In valuing equity securities (including warrants), the Company estimates fair value using an “Enterprise Value Waterfall” valuation model. The Company estimates the enterprise value of a portfolio company and then allocates the enterprise value to the portfolio company's securities in order of their relative liquidation preference. In addition, the Company assumes that any outstanding debt or other securities that are senior to the Company’s equity securities are required to be repaid at par.

To estimate the enterprise value of the portfolio company, the Company primarily uses a valuation model based on a transaction multiple, which generally is the original transaction multiple, and measures of the portfolio company’s financial performance. In addition, the Company considers other factors, including but not limited to (i) offers from third-parties to purchase the portfolio company, (ii) the implied value of recent investments in the equity securities of the portfolio company, (iii) publicly available information regarding recent sales of private companies in comparable transactions and, (iv) when the Company believes there are comparable companies that are publicly traded, a review of these publicly traded companies and the market multiple of their equity securities.

The significant Level 3 inputs to the Enterprise Value Waterfall model are (i) an appropriate transaction multiple and (ii) a measure of the portfolio company’s financial performance, which generally is either earnings

before interest, taxes, depreciation and amortization, as adjusted (“Adjusted EBITDA”) or revenues. Such inputs can be based on historical operating results, projections of future operating results, or a combination thereof. The operating results of a portfolio company may be unaudited, projected or pro forma financial information and may require adjustments for certain non-recurring items. In determining the operating results input, the Company utilizes the most recent portfolio company financial statements and forecasts available as of the valuation date. The Company also consults with the portfolio company’s senior management to obtain updates on the portfolio company’s performance, including information such as industry trends, new product development, loss of customers and other operational issues. Fair value measurements using the Enterprise Value Waterfall model can be sensitive to significant changes in one or more of the inputs. A significant increase in either the transaction multiple, Adjusted EBITDA or revenues for a particular equity security would result in a higher fair value for that security.

Income Approach

In valuing debt securities, the Company utilizes an “Income Approach” model that considers factors including, but not limited to, (i) the stated yield on the debt security, (ii) the portfolio company’s current trailing twelve months’ (“TTM”) Adjusted EBITDA as compared to the portfolio company’s historical or projected Adjusted EBITDA as of the date the investment was made and the portfolio company’s anticipated Adjusted EBITDA for the next twelve months of operations, (iii) the portfolio company’s current Leverage Ratio (defined as the portfolio company’s total indebtedness divided by Adjusted EBITDA) as compared to its Leverage Ratio as of the date the investment was made, (iv) publicly available information regarding current pricing and credit metrics for similar proposed and executed investment transactions of private companies and (v) when the Company believes a relevant comparison exists, current pricing and credit metrics for similar proposed and executed investment transactions of publicly traded debt. In addition, the Company uses a risk rating system to estimate the probability of default on the debt securities and the probability of loss if there is a default. This risk rating system covers both qualitative and quantitative aspects of the business and the securities held.

The Company considers the factors above, particularly any significant changes in the portfolio company’s results of operations and leverage, and develops an expectation of the yield that a hypothetical market participant would require when purchasing the debt investment (the “Required Rate of Return”). The Required Rate of Return, along with the Leverage Ratio and Adjusted EBITDA are the significant Level 3 inputs to the Income Approach model. For investments where the Leverage Ratio and Adjusted EBITDA have not fluctuated significantly from the date the investment was made or have not fluctuated significantly from the Company’s expectations as of the date the investment was made, and where there have been no significant fluctuations in the market pricing for such investments, the Company may conclude that the Required Rate of Return is equal to the stated rate on the investment and therefore, the debt security is appropriately priced. In instances where the Company determines that the Required Rate of Return is different from the stated rate on the investment, the Company discounts the contractual cash flows on the debt instrument using the Required Rate of Return in order to estimate the fair value of the debt security.

Fair value measurements using the Income Approach model can be sensitive to significant changes in one or more of the inputs. A significant increase (decrease) in the Required Rate of Return or Leverage Ratio inputs for a particular debt security may result in a lower (higher) fair value for that security. A significant increase (decrease) in the Adjusted EBITDA input for a particular debt security may result in a higher (lower) fair value for that security.

The fair value of the Company’s royalty rights are calculated based on specific provisions contained in the pertinent operating or royalty agreements. The determination of the fair value of such royalty rights is not a significant component of the Company’s valuation process.

All realized and unrealized gains and losses are included in earnings (changes in net assets) and are reported on separate line items within the Company’s statements of operations. Pre-tax net unrealized gains on investments of $0.8 million during the three months ended March 31, 2012 are related to portfolio company investments that were still held by the Company as of March 31, 2012. Pre-tax net unrealized gains on investments of $4.8 million during the three months ended March 31, 2011 are related to portfolio company investments that were still held by the Company as of March 31, 2011.

Warrants

When originating a debt security, the Company will sometimes receive warrants or other equity–related securities from the borrower. The Company determines the cost basis of the warrants or other equity–related securities received based upon their respective fair values on the date of receipt in proportion to the total fair value of the debt and warrants or other equity–related securities received. Any resulting difference between the face amount of the debt and its recorded fair value resulting from the assignment of value to the warrant or other equity instruments is treated as original issue discount and accreted into interest income over the life of the loan.

Realized Gain or Loss and Unrealized Appreciation or Depreciation of Portfolio Investments

Realized gains or losses are recorded upon the sale or liquidation of investments and are calculated as the difference between the net proceeds from the sale or liquidation, if any, and the cost basis of the investment using the specific identification method. Unrealized appreciation or depreciation reflects the difference between the fair value of the investments and the cost basis of the investments.

Investment Classification

In accordance with the provisions of the 1940 Act, the Company classifies investments by level of control. As defined in the 1940 Act, “Control Investments” are investments in those companies that the Company is deemed to “Control.” “Affiliate Investments” are investments in those companies that are “Affiliated Companies” of the Company, as defined in the 1940 Act, other than Control Investments. “Non–Control/Non–Affiliate Investments” are those that are neither Control Investments nor Affiliate Investments. Generally, under the 1940 Act, the Company is deemed to control a company in which it has invested if the Company owns more than 25.0% of the voting securities of such company or has greater than 50.0% representation on its board. The Company is deemed to be an affiliate of a company in which the Company has invested if it owns between 5.0% and 25.0% of the voting securities of such company.

Investment Income

Interest income, adjusted for amortization of premium and accretion of original issue discount, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the loan on non-accrual status and will generally cease recognizing interest income on that loan until all principal and interest has been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any previously accrued and uncollected interest when it is determined that interest is no longer considered collectible. Dividend income is recorded on the ex–dividend date.

Fee Income

Origination, facility, commitment, consent and other advance fees received in connection with loan agreements (“Loan Origination Fees”) are recorded as deferred income and recognized as investment income over the term of the loan. Upon prepayment of a loan, any unamortized loan origination fees are recognized as

investment income. In the general course of its business, the Company receives certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received.

Payment-in-Kind Interest

The Company currently holds, and expects to hold in the future, some loans in its portfolio that contain a payment–in–kind (“PIK”) interest provision. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan, rather than being paid to us in cash, and is recorded as interest income. Thus, the actual collection of PIK interest may be deferred until the time of debt principal repayment.

To maintain the Company’s status as a Regulated Investment Company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as Amended (the “Code”), PIK interest, which is a non-cash source of income, is included in the Company’s taxable income and therefore affects the amount it is required to pay to stockholders in the form of dividends, even though the Company has not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the loan on non-accrual status and will generally cease recognizing PIK interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any accrued and uncollected PIK interest when it is determined that the PIK interest is no longer collectible.

Concentration of Credit Risk

The Company’s investments are generally in lower middle–market companies in a variety of industries. At both March 31, 2012 and December 31, 2011, there were no individual investments greater than 10% of the fair value of the Company’s portfolio. As of March 31, 2012 and December 31, 2011, the Company’s largest single portfolio company investment represented approximately 4.7% and 5.0%, respectively, of the fair value of the Company’s portfolio. Income, consisting of interest, dividends, fees, other investment income, and realization of gains or losses on equity interests, can fluctuate dramatically upon repayment of an investment or sale of an equity interest and in any given year can be highly concentrated among several portfolio companies.

The Company’s investments carry a number of risks including, but not limited to: 1) investing in lower middle market companies which have limited operating histories and financial resources; 2) investing in senior subordinated debt which ranks equal to or lower than debt held by other investors; and 3) holding investments that are not publicly traded and are subject to legal and other restrictions on resale, as well as other risks common to investing in below investment grade debt and equity instruments.

3. | INCOME TAXES

The Company has elected for federal income tax purposes to be treated as a RIC under the Code, and intends to make the required distributions to its stockholders as specified therein. In order to qualify as a RIC, the Company must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then the Company is generally required to pay income taxes only on the portion of its taxable income and gains it does not distribute (actually or constructively) and certain built-in gains. The Company met its minimum distribution requirements for 2011, 2010 and 2009 and continually monitors its distribution requirements with the goal of ensuring compliance with the Code.

TRIANGLE CAPITAL CORPORATION

Notes to Unaudited Consolidated Financial Statements — (Continued)

The minimum distribution requirements applicable to RICs require the Company to distribute to its stockholders at least 90% of its investment company taxable income (“ICTI”), as defined by the Code, each year. Depending on the level of ICTI earned in a tax year, the Company may choose to carry forward ICTI in excess of current year distributions into the next tax year and pay a 4% excise tax on such excess. Any such carryover ICTI must be distributed before the end of that next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI.

ICTI generally differs from net investment income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. The Company may be required to recognize ICTI in certain circumstances in which it does not receive cash. For example, if the Company holds debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments issued with warrants), the Company must include in ICTI 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 the Company in the same taxable year. The Company may also have to include in ICTI other amounts that it has not yet received in cash, such as (i) PIK interest income and (ii) interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. Because any original issue discount or other amounts accrued will be included in the Company’s ICTI for the year of accrual, the Company may be required to make a distribution to its stockholders in order to satisfy the minimum distribution requirements, even though the Company will not have received and may not ever receive any corresponding cash amount. ICTI also excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

The Company has certain wholly owned taxable subsidiaries (the “Taxable Subsidiaries”) each of which holds one or more of the Company’s portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiaries are consolidated for financial reporting purposes, such that the Company’s consolidated financial statements reflect the Company’s investments in the portfolio companies owned by the Taxable Subsidiaries. The purpose of the Taxable Subsidiaries is to permit the Company to hold certain portfolio companies that are organized as limited liability companies (“LLCs”) (or other forms of pass–through entities) while satisfying the RIC tax requirement that at least 90% of the RIC’s gross revenue for income tax purposes must consist of qualifying investment income. Absent the Taxable Subsidiaries, a proportionate amount of any gross income of an LLC (or other pass–through entity) portfolio investment would flow through directly to the RIC. To the extent that such income did not consist of qualifying investment income, it could jeopardize the Company’s ability to qualify as a RIC and therefore cause the Company to incur significant amounts of federal income taxes. When LLCs (or other pass-through entities) are owned by the Taxable Subsidiaries, their income is taxed to the Taxable Subsidiaries and does not flow through to the RIC, thereby helping the Company preserve its RIC status and resultant tax advantages. The Taxable Subsidiaries are not consolidated for income tax purposes and may generate income tax expense as a result of their ownership of the portfolio companies. This income tax expense is reflected in the Company’s Statements of Operations.

For federal income tax purposes, the cost of investments owned at March 31, 2012 was approximately $537.4 million.

SBA and SBA LMI Debentures

Interest payments on SBA debentures are payable semi–annually and there are no principal payments required on these debentures prior to maturity, nor do the debentures carry any prepayment penalties. The Company’s SBA Low or Moderate Income (“LMI”) debentures are five-year deferred interest debentures that are issued at a discount to par. The accretion of discount on SBA LMI debentures is classified as interest expense in the Company’s consolidated financial statements.

Under the Small Business Investment Act and current SBA policy applicable to SBICs, an SBIC (or group of SBICs under common control) can have outstanding at any time, SBA-guaranteed debentures up to two times (and in certain cases, up to three times) the amount of its regulatory capital. As of March 31, 2012, the maximum statutory limit on the dollar amount of outstanding SBA-guaranteed debentures that can be issued by a single SBIC is $150.0 million and by a group of SBICs under common control is $225.0 million. As of March 31, 2012, Triangle SBIC has issued $139.6 million of SBA-guaranteed debentures and has the current capacity to issue up to the statutory maximum of $150.0 million, subject to SBA approval. As of March 31, 2012, Triangle SBIC II has issued $75.0 million in face amount of SBA-guaranteed debentures. The weighted average interest rates for all SBA-guaranteed debentures as of March 31, 2012 and December 31, 2011 were 4.76% and 4.83%, respectively.

In addition to a one–time 1.0% fee on the total commitment from the SBA, the Company also pays a one–time 2.425% fee on the amount of each SBA-guaranteed debenture issued and a one-time 2.0% fee on the amount of each SBA-guaranteed LMI debenture issued. These fees are capitalized as deferred financing costs and are amortized over the term of the debt agreements using the effective interest method. Upon prepayment of an SBA-guaranteed debenture, any unamortized deferred financing costs related to the SBA-guaranteed debenture are written off and recognized as a loss on extinguishment of debt in the Consolidated Statements of

Operations. In the three months ended March 31, 2012 and 2011, the Company prepaid approximately $10.4 million and $9.5 million, respectively, of SBA-guaranteed debentures and recognized losses on extinguishment of debt of approximately $0.2 million in each respective period.

Credit Facility

In May 2011, the Company entered into a three-year senior secured credit facility with an initial commitment of $50.0 million (the “Credit Facility”). In November 2011, we closed an expansion of the Credit Facility, which included the addition of one new lender, from $50.0 million to $75.0 million. The purpose of the Credit Facility is to provide additional liquidity in support of future investment and operational activities. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and has an accordion feature which allows for an increase in the total loan size up to $90.0 million and also contains two one-year extension options, bringing the total potential commitment and funding period to five years from closing. The Credit Facility, which is structured to operate like a revolving credit facility, is secured primarily by Triangle Capital Corporation’s assets, excluding the assets of Triangle SBIC and Triangle SBIC II.

Borrowings under the Credit Facility bear interest, subject to the Company’s election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or (ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of (i) prime rate, (ii) the federal funds rate plus 0.5% or (iii) the adjusted one-month LIBOR plus 2.0%. The Company pays unused commitment fees of 0.375% per annum, which are included with Interest and other credit facility fees on the Company’s Consolidated Statement of Operations. As of March 31, 2012, the Company had no borrowings outstanding under the Credit Facility. As of December 31, 2011, the Company had $15.0 million in borrowings outstanding under the Credit Facility with an interest rate of 5.2%.

The Credit Facility contains certain affirmative and negative covenants, including but not limited to (i) maintaining a minimum interest coverage ratio, (ii) maintaining a minimum liquidity ratio and (iii) maintaining minimum consolidated tangible net worth. As of March 31, 2012, the Company was in compliance with all covenants of the Credit Facility.

Senior Notes Due 2019

In March 2012, the Company issued $69.0 million of senior unsecured notes (the “Senior Notes”). The Senior Notes mature on March 15, 2019, and may be redeemed in whole or in part at any time or from time to time at the Company’s option on or after March 15, 2015. The Senior Notes bear interest at a rate of 7.00% per year payable quarterly on March 15, June 15, September 15 and December 15 of each year, beginning June 15, 2012. The net proceeds to the Company from the sale of the Senior Notes, after underwriting discounts and offering expenses, were approximately $66.8 million.

5. | EQUITY-BASED AND OTHER COMPENSATION PLANS

The Company’s Board of Directors and stockholders have approved the Triangle Capital Corporation Amended and Restated 2007 Equity Incentive Plan (the “Plan”), under which there are 900,000 shares of the Company’s Common Stock authorized for issuance. Under the Plan, the Board of Directors (or Compensation Committee, if delegated administrative authority by the Board of Directors) may award stock options, restricted stock or other stock based incentive awards to executive officers, employees and directors. Equity-based awards granted under the Plan to independent directors generally will vest over a one-year period and equity-based awards granted under the Plan to executive officers and employees generally will vest ratably over a four-year period.

The Company accounts for its equity-based compensation plan using the fair value method, as prescribed by ASC Topic 718, 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 this fair value to compensation expense over the requisite service period or vesting term.

The following table presents information with respect to the Plan for the three months ended March 31, 2012 and 2011:

|  | Three Months Ended March 31, 2012 |  |  | Three Months Ended March 31, 2011 |
|  | Number of Shares |  |  | Weighted-Average Grant-Date Fair Value per Share |  |  | Number of Shares |  |  | Weighted-Average Grant-Date Fair Value per Share |
Unvested shares, beginning of period |  |  | 359,555 |  |  | $ | 15.39 |  |  |  | 302,698 |  |  | $ | 11.40 |
Shares granted during the period |  |  | 227,631 |  |  | $ | 18.96 |  |  |  | 152,779 |  |  | $ | 20.51 |
Shares vested during the period |  |  | (107,067 | ) |  | $ | 13.61 |  |  |  | (68,873 | ) |  | $ | 11.25 |
Unvested shares, end of period |  |  | 480,119 |  |  | $ | 17.48 |  |  |  | 386,604 |  |  | $ | 15.03 |

In the three months ended March 31, 2012 and 2011, the Company recognized equity-based compensation expense of approximately $0.6 million and $0.4 million, respectively. This expense is included in general and administrative expenses in the Company’s consolidated statements of operations. As of March 31, 2012, there was approximately $7.5 million of total unrecognized compensation cost, related to the Company’s non-vested restricted shares. This cost is expected to be recognized over a weighted-average period of approximately 2.2 years.

The Company’s Board of Directors has adopted a nonqualified deferred compensation plan covering the Company’s executive officers and key employees. Any compensation deferred and the Company’s contributions will earn a return based on the returns on certain investments designated by the Compensation Committee of the Company’s Board of Directors. Participants are 100% vested in amounts deferred under the plan and the earnings thereon. Contributions to the plan and earnings thereon vest ratably over a four-year period.

The Company maintains a 401(k) plan in which all full-time employees who are at least 21 years of age and have 90 days of service are eligible to participate and receive employer contributions. Eligible employees may contribute a portion of their compensation on a pretax basis into the 401(k) plan up to the maximum amount allowed under the Code, and direct the investment of their contributions.

We have also audited the accompanying consolidated financial highlights for each of the five years in the period ended December 31, 2011. These financial statements and financial highlights are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2011 and 2010 by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the consolidated financial position of Triangle Capital Corporation at December 31, 2011 and 2010, the consolidated results of its operations, changes in net assets, and its cash flows, for each of the three years in the period in the period ended December 31, 2011, and the consolidated financial highlights for each of the five years in the period ended December 31, 2011, in conformity with U.S. generally accepted accounting principles.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders

Triangle Capital Corporation

We have audited Triangle Capital Corporation’s internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Triangle Capital Corporation’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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.

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.

In our opinion, Triangle Capital Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Triangle Capital Corporation (the Company), including the consolidated schedules of investments, as of December 31, 2011 and 2010, and 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, 2011. We have also audited the accompanying consolidated financial highlights for each of the five years in the period ended December 31, 2011 and our report dated March 7, 2012 expressed an unqualified opinion thereon.

Notes to Financial Statements

1. | Organization, Basis of Presentation and Summary of Significant Accounting Policies

Organization

Triangle Capital Corporation (the “Company”) was incorporated on October 10, 2006 for the purposes of acquiring 100% of the equity interest in Triangle Mezzanine Fund LLLP (“Triangle SBIC”) and its general partner, Triangle Mezzanine LLC (“TML”), raising capital in an initial public offering, which was completed in February 2007 (the “IPO”) and thereafter operating as an internally managed Business Development Company (“BDC”) under the Investment Company Act of 1940 (the “1940 Act”). On December 15, 2009, Triangle Mezzanine Fund II, LP (“Triangle SBIC II”) was organized as a limited partnership under the laws of the State of Delaware. Unless otherwise noted, the terms “its” or “the Company” refer to Triangle SBIC prior to the IPO and to Triangle Capital Corporation and its subsidiaries, including Triangle SBIC and Triangle SBIC II, after the IPO.

Triangle SBIC and Triangle SBIC II are specialty finance limited partnerships formed to make investments primarily in middle market companies located throughout the United States. On September 11, 2003, Triangle SBIC was licensed to operate as a Small Business Investment Company (“SBIC”) under the authority of the United States Small Business Administration (“SBA”). On May 26, 2010, Triangle SBIC II obtained its license to operate as an SBIC. As SBICs, both Triangle SBIC and Triangle SBIC II are subject to a variety of regulations concerning, among other things, the size and nature of the companies in which they may invest and the structure of those investments.

On February 21, 2007, concurrent with the closing of the IPO, the following formation transactions were consummated (the “Formation Transactions”):

| • |  | The Company acquired 100% of the limited partnership interests in Triangle SBIC in exchange for approximately 1.9 million shares of the Company’s common stock. Triangle SBIC became a wholly-owned subsidiary of the Company, retained its license under the authority of the SBA to operate as an SBIC and continues to hold its existing investments and make new investments with the proceeds of the IPO; and

| • |  | The Company acquired 100% of the equity interests in TML, and the management agreement between Triangle SBIC and Triangle Capital Partners, LLC was terminated.

The IPO consisted of the sale of 4,770,000 shares of Common Stock at a price of $15 per share, resulting in net proceeds of approximately $64.7 million, after deducting offering costs totaling approximately $6.8 million. Upon completion of the IPO, the Company had 6,686,760 common shares outstanding.

As a result of completion of the IPO and formation transactions, Triangle SBIC became a 100% wholly-owned subsidiary of the Company. The General partner of Triangle SBIC is the New General Partner (which is wholly-owned by the Company) and the limited partners of Triangle SBIC are the Company (99.9%) and the New General Partner (0.1%).

The Company currently operates as a closed–end, non–diversified investment company and has elected to be treated as a BDC under the 1940 Act. The Company is internally managed by its executive officers under the supervision of its Board of Directors. The Company does not pay management or advisory fees, but instead incurs the operating costs associated with employing executive management and investment and portfolio management professionals.

Basis of Presentation

The financial statements of the Company include the accounts of the Company and its wholly-owned subsidiaries, including Triangle SBIC and Triangle SBIC II. Neither Triangle SBIC nor Triangle SBIC II consolidates portfolio company investments. The effects of all intercompany transactions between the Company and its subsidiaries have been eliminated in consolidation.

Notes to Financial Statements — (Continued)

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The Formation Transactions discussed above involved an exchange of shares of the Company’s common stock between companies under common control. In accordance with the guidance on exchanges of shares between entities under common control contained in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (formerly Statement of Financial Accounting Standards (“SFAS”) No. 141, Business Combinations (“SFAS 141”), the Company’s financial highlights for the year ended December 31, 2007 are presented as if the Formation Transactions had occurred as of January 1, 2007. The effects of all intercompany transactions between the Company and its subsidiaries have been eliminated in consolidation/combination. All financial data and information included in these financial statements have been presented on the basis described above.

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Valuation of Investments

The Company has established and documented processes and methodologies for determining the fair values of portfolio company investments on a recurring basis in accordance with FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”). Under ASC Topic 820, a financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of valuation hierarchy established by ASC Topic 820 are defined as follows:

Level 1 — inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 — inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The Company’s investment portfolio is comprised of debt and equity instruments of privately held companies for which quoted prices falling within the categories of Level 1 and Level 2 inputs are not available. Therefore, the Company values all of its investments at fair value, as determined in good faith by the Board of Directors, using Level 3 inputs, as further described below. Due to the inherent uncertainty in the valuation process, the Board of Directors’ estimate of fair value may differ significantly from the values that would have been used had a ready market for the securities existed, and the differences could be material. In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the valuations currently assigned.

Debt and equity securities that are not publicly traded and for which a limited market does not exist are valued at fair value as determined in good faith by the Board of Directors. There is no single standard for determining fair value in good faith, as fair value depends upon circumstances of each individual case. In general, fair value is the amount that the Company might reasonably expect to receive upon the current sale of the security.

Notes to Financial Statements — (Continued)

Management evaluates the investments in portfolio companies using the most recent portfolio company financial statements and forecasts. Management also consults with the portfolio company’s senior management to obtain further updates on the portfolio company’s performance, including information such as industry trends, new product development and other operational issues.

In making the good faith determination of the value of debt securities, the Company starts with the cost basis of the security, which includes the amortized original issue discount, and payment — in — kind (“PIK”) interest, if any. The Company also uses a risk rating system to estimate the probability of default on the debt securities and the probability of loss if there is a default. The risk rating system covers both qualitative and quantitative aspects of the business and the securities held. In valuing debt securities, management utilizes an “income approach” model that considers factors including, but not limited to, (i) the portfolio investment’s current risk rating, (ii) the portfolio company’s current trailing twelve months’ (“TTM”) results of operations as compared to the portfolio company’s TTM results of operations as of the date the investment was made and the portfolio company’s anticipated results for the next twelve months of operations, (iii) the portfolio company’s current leverage as compared to its leverage as of the date the investment was made, (iv) publicly available information regarding current pricing and credit metrics for similar proposed and executed investment transactions of private companies and, (v) when management believes a relevant comparison exists, current pricing and credit metrics for similar proposed and executed investment transactions of publicly traded debt.

In valuing equity securities of private companies, the Company considers valuation methodologies consistent with industry practice, including but not limited to (i) valuation using a valuation model based on original transaction multiples and the portfolio company’s recent financial performance, (ii) publicly available information regarding the valuation of the securities based on recent sales in comparable transactions of private companies and, (iii) when management believes there are comparable companies that are publicly traded, a review of these publicly traded companies and the market multiple of their equity securities.

Duff & Phelps, LLC (“Duff & Phelps”), an independent valuation firm, provides third party valuation consulting services to the Company which consist of certain limited procedures that the Company identified and requested Duff & Phelps to perform (hereinafter referred to as the “procedures”). The Company generally requests Duff & Phelps to perform the procedures on each portfolio company at least once in every calendar year and for new portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In addition, the Company generally requests Duff & Phelps to perform the procedures on a portfolio company when there has been a significant change in the fair value of the investment. In certain instances, the Company may determine that it is not cost-effective, and as a result is not in the Company’s stockholders’ best interest, to request Duff & Phelps to perform the procedures on one or more portfolio companies. Such instances include, but are not limited to, situations where the fair value of the Company’s investment in the portfolio company is determined to be insignificant relative to the Company’s total investment portfolio.

The total number of investments and the percentage of the Company’s portfolio that the Company asked Duff & Phelps to perform such procedures are summarized below by period:

For the quarter ended: |  | Total companies |  |  | Percent of total investments at fair value(1) |
March 31, 2009 |  |  | 7 |  |  |  | 26 | %

December 31, 2011 |  |  | 12 |  |  |  | 22 | %

(1) | Exclusive of the fair value of new investments made during the quarter

Upon completion of the procedures, Duff & Phelps concluded that the fair value, as determined by the Board of Directors, of those investments subjected to the procedures appeared reasonable. The Board of Directors of Triangle Capital Corporation is ultimately and solely responsible for determining the fair value of the Company’s investments in good faith.

Warrants

When originating a debt security, the Company will sometimes receive warrants or other equity — related securities from the borrower. The Company determines the cost basis of the warrants or other equity — related securities received based upon their respective fair values on the date of receipt in proportion to the total fair value of the debt and warrants or other equity — related securities received. Any resulting difference between the face amount of the debt and its recorded fair value resulting from the assignment of value to the warrant or other equity instruments is treated as original issue discount and accreted into interest income over the life of the loan.

Realized Gain or Loss and Unrealized Appreciation or Depreciation of Portfolio Investments

Realized gains or losses are recorded upon the sale or liquidation of investments and are calculated as the difference between the net proceeds from the sale or liquidation, if any, and the cost basis of the investment using the specific identification method. Unrealized appreciation or depreciation reflects the difference between the fair value of the investments and the cost basis of the investments.

Investment Classification

In accordance with the provisions of the 1940 Act, the Company classifies investments by level of control. As defined in the 1940 Act, “Control Investments” are investments in those companies that the Company is deemed to “Control.” “Affiliate Investments” are investments in those companies that are “Affiliated Companies” of the Company, as defined in the 1940 Act, other than Control Investments. “Non — Control/Non — Affiliate Investments” are those that are neither Control Investments nor Affiliate Investments. Generally, under the 1940 Act, the Company is deemed to control a company in which it has invested if the Company owns

more than 25.0% of the voting securities of such company or has greater than 50.0% representation on its board. The Company is deemed to be an affiliate of a company in which the Company has invested if it owns between 5.0% and 25.0% of the voting securities of such company.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents.

Deferred Financing Fees

Costs incurred to issue long — term debt are capitalized and are amortized over the term of the debt agreements using the effective interest method.

Depreciation

Furniture, fixtures and equipment are depreciated on a straight-line basis over an estimated useful life of five years. Software and computer equipment are depreciated over an estimated useful life of three years.

Investment Income

Interest income, adjusted for amortization of premium and accretion of original issue discount, is recorded on the accrual basis to the extent that such amounts are expected to be collected. Generally, when interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the loan on non-accrual status and will generally cease recognizing interest income on that loan for financial reporting purposes, until all principal and interest has been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any previously accrued and uncollected interest when it is determined that interest is no longer considered collectible. Dividend income is recorded on the ex — dividend date.

Payment in Kind Interest

The Company currently holds, and expects to hold in the future, some loans in its portfolio that contain a payment — in — kind (“PIK”) interest provision. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan, rather than being paid to the Company in cash, and is recorded as interest income. Thus, the actual collection of PIK interest may be deferred until the time of debt principal repayment.

To maintain the Company’s status as a Regulated Investment Company (“RIC”) for federal income tax purposes, PIK interest, which is a non-cash source of income, is included in the Company’s taxable income and therefore affects the amount it is are required to pay to stockholders in the form of dividends, even though the Company has not yet collected the cash. Generally, when current cash interest and/or principal payments on a loan become past due, or if the Company otherwise does not expect the borrower to be able to service its debt and other obligations, the Company will place the loan on non-accrual status and will generally cease recognizing PIK interest income on that loan for financial reporting purposes until all principal and interest have been brought current through payment or due to a restructuring such that the interest income is deemed to be collectible. The Company writes off any accrued and uncollected PIK interest when it is determined that the PIK interest is no longer collectible.

Fee Income

Loan origination, facility, commitment, consent and other advance fees received in connection with the loan agreements are recorded as deferred income and recognized as investment income over the term of the loan. Upon prepayment of a loan, any unamortized loan origination fees are recorded as interest income. In the general course of its business, the Company receives certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, certain investment banking and structuring fees and loan waiver and amendment fees, and are recorded as investment income when received.

Income Taxes

The Company has elected for federal income tax purposes to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). As a RIC, so long as certain minimum distribution, source-of-income and asset diversification requirements are met income taxes are generally required to be paid only on the portion of taxable income and gains that are not distributed (actually or constructively) and on certain built-in gains.

The company has certain wholly-owned taxable subsidiaries (the “Taxable Subsidiaries”), each of which holds one or more of its portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiaries are consolidated for financial reporting purposes, such that the company’s consolidated financial statements reflect the Company’s investments in the portfolio companies owned by the Taxable Subsidiaries. The purpose of the Taxable Subsidiaries is to permit the Company to hold certain portfolio companies that are organized as limited liability companies (“LLCs”) (or other forms of pass — through entities) while satisfying the RIC tax requirement that at least 90% of the RIC’s gross revenue for income tax purposes must consist of qualifying investment income. Absent the Taxable Subsidiaries, a proportionate amount of any gross income of an LLC (or other pass — through entity) portfolio investment would flow through directly to the RIC. To the extent that such income did not consist of qualifying investment income, it could jeopardize the Company’s ability to qualify as a RIC and therefore cause the Company to incur significant amounts of federal income taxes. When LLCs (or other pass-through entities) are owned by the Taxable Subsidiaries, their income is taxed to the Taxable Subsidiaries and does not flow through to the RIC, thereby helping the Company preserve its RIC status and resultant tax advantages. The Taxable Subsidiaries are not consolidated for income tax purposes and may generate income tax expense as a result of their ownership of the portfolio companies. This income tax expense is reflected in the Company’s Statements of Operations.

Segments

The Company lends to and invests in customers in various industries. The Company separately evaluates the performance of each of its lending and investment relationships. However, because each of these loan and investment relationships has similar business and economic characteristics, they have been aggregated into a single lending and investment segment. All applicable segment disclosures are included in or can be derived from the Company’s financial statements.

Concentration of Credit Risk

The Company’s investees are generally lower middle — market companies in a variety of industries. At both December 31, 2011 and 2010, there were no individual investments greater than 10% of the fair value of the Company’s portfolio. Income, consisting of interest, dividends, fees, other investment income, and realization of gains or losses on equity interests, can fluctuate dramatically upon repayment of an investment or sale of an equity interest and in any given year can be highly concentrated among several investees.

Dividends and Distributions

Dividends and distributions to common stockholders are approved by the Company’s Board of Directors and the dividend payable is recorded on the ex-dividend date.

The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of dividends on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, when the Company declares a dividend, stockholders who have not opted out of the DRIP will have their dividends automatically reinvested in shares of the Company’s common stock, rather than receiving cash dividends.

The table below summarizes the Company’s dividends and distributions:

Per Share Amounts

Per share amounts included in the Statements of Operations are computed by dividing net investment income and net increase in net assets resulting from operations by the weighted average number of shares of common stock outstanding for the period. As the Company has no common stock equivalents outstanding, diluted per share amounts are the same as basic per share amounts. Net asset value per share is computed by dividing total net assets by the number of common shares outstanding as of the end of the period.

Recently Issued Accounting Standards

In April 2011, the FASB issued ASU No. 2011-02 — A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring, or ASU 2011-02. This standard amends previous guidance provided in Accounting Standards Codification 310-40 — Receivables — Troubled Debt Restructuring by Creditors and clarifies which loan modifications constitute troubled debt restructurings. It is intended to assist creditors in determining whether a modification of the terms of a receivable meets the criteria to be considered a troubled debt restructuring, both for purposes of recording an impairment loss and for disclosure of troubled debt restructurings. In evaluating whether a restructuring constitutes a troubled debt restructuring, a creditor must separately conclude that both of the following exist: (a) the restructuring constitutes a concession; and (b) the debtor is experiencing financial difficulties. ASU 2011-02 provides guidance to clarify whether the creditor has granted a concession and whether a debtor is experiencing financial difficulties. The new guidance is effective for interim and annual periods that began on or after June 15, 2011, and applies retrospectively to restructurings occurring on or after the beginning of the fiscal year of adoption. The adoption of ASU 2011-02 did not have a significant impact on our financial position or results of operations.

In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, or ASU 2011-04. ASU 2011-04 clarifies the application of existing fair value measurement and disclosure requirements, changes the application of some requirements for measuring fair value and requires additional disclosure for fair value measurements categorized in Level 3 of the fair value hierarchy. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. We will adopt this standard beginning on January 1, 2012. We are evaluating the impact, if any, that our adoption of this update may have on our financial position or results of operations. However, since this accounting standards update primarily requires expanded disclosure related to Category 3 financial assets and liabilities, we do not anticipate that the implementation of this standard will have a significant impact on our process for measuring fair values, our financial position or results of operations.

SBA and SBA LMI Debentures

Interest payments on SBA debentures are payable semi–annually and there are no principal payments required on these debentures prior to maturity, nor do the debentures carry any prepayment penalties. The Company’s SBA Low or Moderate Income (“LMI”) debentures are five-year deferred interest debentures that are issued at a discount to par. The accretion of discount on SBA LMI debentures is classified as interest expense in the Company’s consolidated financial statements.

Under the Small Business Investment Act and current SBA policy applicable to SBICs, an SBIC (or group of SBICs under common control) can have outstanding at any time, SBA-guaranteed debentures up to two times (and in certain cases, up to three times) the amount of its regulatory capital. As of December 31, 2011, the maximum statutory limit on the dollar amount of outstanding SBA-guaranteed debentures that can be issued by a single SBIC is $150.0 million and by a group of SBICs under common control is $225.0 million. As of December 31, 2011, Triangle SBIC has issued the maximum $150.0 million of SBA- guaranteed debentures and Triangle SBIC II has issued the maximum $75.0 million in face amount of SBA-guaranteed debentures. In addition to a one–time 1.0% fee on the total commitment from the SBA, the Company also pays a one–time 2.425% fee on the amount of each SBA debenture issued and a one-time 2.0% fee on the amount of each SBA LMI debenture issued. These fees are capitalized as deferred financing costs and are amortized over the term of the debt agreements using the effective interest method. The weighted average interest rates for all SBA-guaranteed debentures as of December 31, 2011 and 2010 were 4.83% and 3.95%, respectively. As of December 31, 2011, all SBA debentures have been pooled. The weighted average interest rate as of December 31, 2010 included $139.1 million of pooled SBA-guaranteed debentures with a weighted average fixed interest rate of 5.29% and $63.4 million of unpooled SBA-guaranteed debentures with a weighted average interim interest rate of 1.00%.

Credit Facility

In May 2011, the Company entered into a three-year senior secured credit facility with an initial commitment of $50.0 million (the “Credit Facility”). In November 2011, we closed an expansion of the Credit Facility, which included the addition of one new lender, from $50.0 million to $75.0 million. The purpose of the Credit Facility is to provide additional liquidity in support of future investment and operational activities. The Credit Facility was arranged by BB&T Capital Markets and Fifth Third Bank and has an accordion feature which allows for an increase in the total loan size up to $90.0 million and also contains two one-year extension options, bringing the total potential commitment and funding period to five years from closing. The Credit Facility, which is structured to operate like a revolving credit facility, is secured primarily by Triangle Capital Corporation’s assets, excluding the assets of Triangle SBIC and Triangle SBIC II.

Borrowings under the Credit Facility bear interest, subject to the Company’s election, on a per annum basis equal to (i) the applicable base rate plus 1.95% or ii) the applicable LIBOR rate plus 2.95%. The applicable base rate is equal to the greater of i) prime rate, ii) the federal funds rate plus 0.5% or iii) the adjusted one-month LIBOR plus 2.0%. The Company pays unused commitment fees of 0.375% per annum, which are included with Interest and other credit facility fees on the Company’s Consolidated Statement of Operations. As of December 31, 2011, the Company had $15.0 million in borrowings outstanding under the Credit Facility with an interest rate of 5.2%.

The Credit Facility contains certain affirmative and negative covenants, including but not limited to i) maintaining a minimum interest coverage ratio, ii) maintaining a minimum liquidity ratio and iii) maintaining minimum consolidated tangible net worth. As of December 31, 2011, the Company was in compliance with all covenants of the Credit Facility.

4. | Income Taxes

The Company has elected to be treated as a RIC under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), and intends to make the required distributions to its stockholders as specified therein. In order to qualify as a RIC, the Company must meet certain minimum distribution, source-of-income and asset diversification requirements. If such requirements are met, then the Company is generally required to pay income taxes only on the portion of its taxable income and gains it does not distribute (actually or constructively) and certain built-in gains. The Company met its minimum distribution requirements for 2011, 2010 and 2009 and continually monitors its distribution requirements with the goal of ensuring compliance with the Code.

The minimum distribution requirements applicable to RICs require the Company to distribute to its stockholders at least 90% of its investment company taxable income (“ICTI”), as defined by the Code, each year. Depending on the level of ICTI earned in a tax year, the Company may choose to carry forward ICTI in excess of current year distributions into the next tax year and pay a 4% excise tax on such excess. Any such carryover ICTI must be distributed before the end of that next tax year through a dividend declared prior to filing the final tax return related to the year which generated such ICTI.

ICTI generally differs from net investment income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. The Company may be required to recognize ICTI in certain circumstances in which it does not receive cash. For example, if the Company holds debt obligations that are treated under applicable tax rules as having original issue discount (such as debt instruments issued with warrants), the Company must include in ICTI 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 the Company in the same taxable year. The Company may also have to include in ICTI other amounts that it has not yet received in cash, such as i) PIK interest income and ii) interest income from investments that have been classified as non-accrual for financial reporting purposes. Interest income on non-accrual investments is not recognized for financial reporting purposes, but generally is recognized in ICTI. Because any original issue discount or other amounts accrued will be included in the Company’s ICTI for the year of accrual, the Company may be required to make a distribution to its stockholders in order to satisfy the minimum distribution requirements, even though the Company will not have received and may not ever receive any corresponding cash amount. ICTI also excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

Permanent differences between ICTI and net investment income for financial reporting purposes are reclassified among capital accounts in the financial statements to reflect their tax character. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes. During the years ended December 31, 2011, 2010 and 2009, the Company reclassified for book purposes amounts arising from permanent book/tax differences primarily related to differences in the tax basis and book basis of investments sold and non-deductible taxes paid during the year as follows:

|  | Years Ended December 31, |
|  | 2011 |  |  | 2010 |  |  | 2009 |
Additional paid-in capital |  | $ | 584,146 |  |  | $ | (171,918 | ) |  | $ | (29,996 | )
Investment income in excess of distributions |  | $ | 638,083 |  |  | $ | 3,385,585 |  |  | $ | 34,125 |
Accumulated realized gains on investments |  | $ | (1,222,229 | ) |  | $ | (3,213,667 | ) |  | $ | (4,129 | )

In addition, the Company has certain wholly-owned taxable subsidiaries (the “Taxable Subsidiaries”), each of which holds one or more of its portfolio investments that are listed on the Consolidated Schedule of Investments. The Taxable Subsidiaries are consolidated for financial reporting purposes, such that the Company’s consolidated

F-72

Notes to Financial Statements — (Continued)

financial statements reflect the Company’s investments in the portfolio companies owned by the Taxable Subsidiaries. The purpose of the Taxable Subsidiaries is to permit the Company to hold certain portfolio companies that are organized as limited liability companies (“LLCs”) (or other forms of pass-through entities) and still satisfy the RIC tax requirement that at least 90% of the RIC’s gross revenue for income tax purposes must consist of investment income. Absent the Taxable Subsidiaries, a proportionate amount of any gross income of an LLC (or other pass-through entity) portfolio investment would flow through directly to the RIC. To the extent that such income did not consist of investment income, it could jeopardize the Company’s ability to qualify as a RIC and therefore cause the Company to incur significant amounts of federal income taxes. When LLCs (or other pass-through entities) are owned by the Taxable Subsidiaries, their income is taxed to the Taxable Subsidiaries and does not flow through to the RIC, thereby helping the Company preserve its RIC status and resultant tax advantages. The Taxable Subsidiaries are not consolidated for income tax purposes and may generate income tax expense as a result of their ownership of the portfolio companies. This income tax expense is reflected in the Company’s Statements of Operations.

For income tax purposes, distributions paid to stockholders are reported as ordinary income, long term capital gains, return of capital or a combination thereof. The tax character of distributions paid for the years ended December 31, 2011, 2010 and 2009 was as follows:

|  | For the Year Ended December 31, |
|  | 2011 |  |  | 2010 |  |  | 2009 |
Ordinary income |  | $ | 35,954,170 |  |  | $ | 20,078,591 |  |  | $ | 14,614,821 |
Distributions of long-term capital gains |  |  | — |  |  |  | 448,164 |  |  |  | 356,495 |
Distributions on a tax basis |  | $ | 35,954,170 |  |  | $ | 20,526,755 |  |  | $ | 14,971,316 |

During the year ended December 31, 2011, the Company utilized net capital loss carryforwards of $8,244,376.

The Company intends to retain some or all of our realized net long-term capital gains in excess of realized net short-term capital losses, but to generally designate the retained net capital gain as a “deemed distribution.” In that case, among other consequences, the Company will pay tax on the retained amount, each U.S. stockholder will be required to include his, her or its share of the deemed distribution in income as if it had been actually distributed to the U.S. stockholder, and the U.S. stockholder will be entitled to claim a credit equal to his, her or its allocable share of the tax paid thereon by us. For the year ended December 31, 2011, the Company elected to designate retained net capital gains of $1,414,949, or approximately $0.06 per share, as a deemed distribution, which will be allocated to stockholders of record as of December 31, 2011. The Company paid U.S. federal income taxes of $495,233, or approximately $0.02 per share, related to the retained capital gains.

At December 31, 2011, 2010 and 2009, the components of distributable earnings on a tax basis detailed below differ from the amounts reflected in the Company’s Statement of Assets and Liabilities by temporary and other book/tax differences, primarily relating to depreciation expense, stock-based compensation, accruals of defaulted debt investment interest and the tax treatment of certain partnership investments, as follows:

|  | As of December 31, |
|  | 2011 |  |  | 2010 |  |  | 2009 |
Undistributed net investment income |  | $ | 8,041,850 |  |  | $ | 4,007,334 |  |  | $ | 1,344,215 |
Accumulated capital (loss) gains |  |  | — |  |  |  | (8,244,376 | ) |  |  | 448,164 |
Other permanent differences relating to the Company’s formation |  |  | 1,975,543 |  |  |  | 1,975,543 |  |  |  | 1,975,543 |
Other temporary differences |  |  | (840,620 | ) |  |  | (892,961 | ) |  |  | (1,001,062 | )
Unrealized appreciation (depreciation) |  |  | 6,790,138 |  |  |  | 15,935 |  |  |  | (10,448,630 | )
Components of distributable earnings at year end |  | $ | 15,966,911 |  |  | $ | (3,138,525 | ) |  | $ | (7,681,770 | )

For federal income tax purposes, the cost of investments owned at December 31, 2011 and 2010 was approximately $500.7 million and $325.8 million, respectively.

5. | Equity Compensation Plan

The Company’s Board of Directors and stockholders have approved the Triangle Capital Corporation Amended and Restated 2007 Equity Incentive Plan (the “Plan”), under which there are 900,000 shares of the Company’s Common Stock authorized for issuance. Under the Plan, the Board (or compensation committee, if delegated administrative authority by the Board) may award stock options, restricted stock or other stock based incentive awards to executive officers, employees and directors. Equity-based awards granted under the Plan to independent directors generally will vest over a one-year period and equity-based awards granted under the Plan to executive officers and employees generally will vest ratably over a four-year period.

The Company accounts for its equity-based compensation plan using the fair value method, as prescribed by ASC Topic 718, Stock Compensation. Accordingly, for restricted stock awards, the Company measures the grant date fair value based upon the market price of the Company’s common stock on the date of the grant and amortizes this fair value to compensation expense over the requisite service period or vesting term.

The following table presents information with respect to the Plan for the years ended December 31, 2011, 2010 and 2009:

|  | Years Ended December 31, |
|  | 2011 |  |  | 2010 |  |  | 2009 |

In the years ended December 31, 2011, 2010 and 2009 the Company recognized equity-based compensation expense of approximately $1.9 million, $1.2 million and $0.7 million, respectively. This expense is included in general and administrative expenses in the Company’s consolidated statements of operations.

As of December 31, 2011, there was approximately $3.8 million of total unrecognized compensation cost, related to the Company’s non-vested restricted shares. This cost is expected to be recognized over a weighted-average period of approximately 1.8 years.

6. | Commitments and Contingencies

In the normal course of business, the Company is party to financial instruments with off-balance sheet risk, consisting primarily of unused commitments to extend credit, in the form of loans, to the Company’s portfolio companies. The balance of unused commitments to extend credit as of December 31, 2011 and 2010 was approximately $17.1 million and $5.1 million, respectively. Since these commitments may expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements.

9. | Subsequent Events

In February 2012, the Company’s Board of Directors granted 227,631 restricted shares of the Company’s common stock to certain employees. These restricted shares had a total grant date fair value of approximately $4.3 million, which will be expensed on a straight-line basis over each respective award’s vesting period.
