(15)Absence of Defaults and Conflicts. No Triangle Entity is (i) in violation of its Organizational Documents, each as amended from time to time, (ii) in breach or default in the performance or observance of any obligation or the terms of any indenture, contract, lease, mortgage, note agreement, loan or credit agreement or other agreement, obligation, condition, covenant or instrument to which it is a party or by which it may be bound or to which its property or assets is subject (collectively, “Agreements and Instruments”) or (iii) in violation of any law, ordinance, administrative or governmental rule or regulation applicable to such Triangle Entity or of any decree of the Commission, any state securities commission, any foreign securities commission, any

national securities exchange, any arbitrator, any court or any other governmental, regulatory, self-regulatory or administrative agency or any official having jurisdiction over such Triangle Entity, except, with respect to clauses (ii) or (iii), to the extent that such breaches, defaults or violations would not, individually or in the aggregate, be reasonably likely to have a Material Adverse Effect.

(16)Non-Contravention. The execution, delivery and performance of this Agreement, the consummation of the transactions contemplated herein and in the Registration Statement, the Preliminary Prospectus and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Preliminary Prospectus and the Prospectus under the caption “Use of Proceeds”), and compliance by the Company with its obligations hereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, (i) conflict with or constitute a breach of, or default or Repayment Event (as defined herein) under, the Agreements and Instruments or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of any Triangle Entity pursuant to the terms of the Agreements and Instruments (except to the extent that such breaches, defaults or creations or impositions would not, individually or in the aggregate, be reasonably likely to have a Material Adverse Effect), (ii) result in any violation of the provisions of the Organizational Documents of any Triangle Entity, in each case as amended from time to time, or (iii) result in any violation of any statute, law, rule, regulation, filing, judgment, order, injunction, writ or decree applicable to any Triangle Entity or any of its assets, properties or operations (except to the extent that such violations would not, individually or in the aggregate, be reasonably likely to have a Material Adverse Effect). As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by a Triangle Entity, as applicable.

(17)Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental, regulatory or self-regulatory agency or body, domestic or foreign, now pending, or, to the Company’s knowledge, threatened, against or affecting any Triangle Entity that is required to be disclosed in the Registration Statement, Preliminary Prospectus or the Prospectus (other than as disclosed therein), or that could reasonably be expected to result in a Material Adverse Effect, or that could reasonably be expected to materially and adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company or any other Triangle Entity of its obligations under this Agreement or the Material Agreements, as applicable. The aggregate of all pending legal or governmental proceedings to which any of the Triangle Entities is a party or of which any of their respective property or assets is the subject that are not described in the Registration Statement, Preliminary Prospectus or the Prospectus, including ordinary routine litigation incidental to the business of the Triangle Entities, could not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

(18)Accuracy of Descriptions and Exhibits. The statements set forth under the headings “Capitalization,” “Risk Factors,” “Business Development Company and Regulated Investment Company Elections,” “Description of Our Capital Stock,” “Regulation” and “Material U.S. Federal Income Tax Considerations” in the Preliminary Prospectus and the Prospectus, and in Item 30 of the Registration Statement, insofar as such statements purport to summarize certain provisions of the 1940 Act, Maryland law, the SBA Regulations, the shares of common stock, the Company’s Organizational Documents, United States federal income tax law and regulations or legal conclusions with respect thereto, fairly and accurately summarize such provisions in all material respects; all descriptions in the Registration Statement, the Preliminary Prospectus and the Prospectus of any Triangle Entity documents are accurate in all material respects.

(19)Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign is necessary or required for the performance by the Company of its obligations under this Agreement in connection with the offering, issuance, sale or delivery of the Securities hereunder, or the consummation of the transactions contemplated by this Agreement, except such as have been already obtained under the 1933 Act, the 1940 Act and the 1934 Act, or as may be required under the rules and regulations of the Financial Industry Regulatory Authority, Inc. (“FINRA”), the New York Stock Exchange or state securities laws.

(20)Possession of Licenses and Permits. Each Triangle Entity has such valid and current licenses, permits, approvals, consents and authorizations of governmental or regulatory authorities (“permits”) as are necessary to own its property and to conduct its business in the manner described in the Preliminary Prospectus and the Prospectus, and no Triangle Entity has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any permits, and no event has occurred which allows or, after notice or lapse of time, would allow, revocation, modification or termination thereof or result in any other material impairment of the rights of any Triangle Entities under any such permit, subject in each case to such qualification as may be set forth in the Preliminary Prospectus and the Prospectus.

(21)Small Business Investment Company Status. Each of the Funds is licensed to operate as a Small Business Investment Company (“SBIC”) by the SBA. Each of the Funds’ respective SBIC license is in good standing with the SBA and no adverse regulatory findings contained in any examinations reports prepared by the SBA regarding either of the Funds are outstanding or unresolved.

(22)SBA Debentures. Each of the Funds is eligible to sell securities guaranteed by the SBA in the amounts and on the terms described in the Preliminary Prospectus and the Prospectus. Neither Fund I, Fund II nor Fund III is in default under the terms of any debenture which it has issued to the SBA for guaranty by the SBA or any other material monetary obligation.

(23)Possession of Intellectual Property. The Triangle Entities own or possess, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on their business as described in the Preliminary Prospectus and the Prospectus. The expected expiration of any of rights to such Intellectual Property would not result in a Material Adverse Effect. The Triangle Entities have not received any notice or are not otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of the Triangle Entities therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, individually or in the aggregate, would result in a Material Adverse Effect. None of the Intellectual Property employed by the Triangle Entities has been obtained or is being used by the Triangle Entities in violation of any contractual obligation binding on any of the Triangle Entities or any of their respective officers, directors or employees or otherwise in violation of the rights of any person.

(24)Distribution of Written Offering Material. The Company has not distributed and will not distribute any written offering material in connection with the offering and sale of the Securities other than the Preliminary Prospectus and the Prospectus, and such materials as may be approved by the Underwriters and comply with the requirements of Rule 482 under the 1933 Act.

(25)Absence of Registration Rights. Except as disclosed in the Preliminary Prospectus and the Prospectus, there are no persons with registration rights or other similar rights to have any securities (debt, equity or otherwise) (i) registered pursuant to the Registration Statement or included in the offering contemplated by this Agreement or (ii) otherwise registered by the Triangle Entities under the 1933 Act or the 1940 Act. There are no persons with “tag-along rights” or other similar rights to have any securities (debt or equity) included in the offering contemplated by this Agreement or sold in connection with the sale of Securities by the Company pursuant to this Agreement.

(26)New York Stock Exchange. The common stock of the Company is registered pursuant to Section 12(b) of the 1934 Act and is listed on the New York Stock Exchange. The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the common stock of the Company under the 1934 Act or delisting the common stock of the Company from the New York Stock Exchange, nor has the Company received any notification that the Commission or the New York Stock Exchange is contemplating terminating such registration or listing. The Company has continued to satisfy, in all material respects, all New York Stock Exchange listing requirements.

(27)FINRA Matters. All of the information provided to the Underwriters or to counsel for the Underwriters by the Company and its officers and directors in connection with letters, filings or other supplemental information provided to FINRA pursuant to FINRA’s conduct rules is true, complete and correct.

(28)Tax Returns. Each of the Triangle Entities has filed all material tax returns that are required to be filed and have paid all taxes required to be paid by it and any other assessment, fine or penalty levied against it, to the extent that any of the foregoing is due and payable, except for any such tax, assessment, fine or penalty that is currently being contested in good faith by appropriate actions and except for such taxes, assessments, fines or penalties the nonpayment of which would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect. The Company has made adequate charges, accruals and reserves in the applicable financial statements referred to in the Preliminary Prospectus and the Prospectus in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of any of the Triangle Entities has not been finally determined. The Company is not aware of any tax deficiency that has been or might be asserted or threatened against any Triangle Entities that could result in a Material Adverse Effect.

(29)Partnership Tax. At all times from the date of its formation until February 21, 2007, Fund I was treated as a partnership for federal income tax purposes, and not as an association or publicly traded partnership taxable as a corporation. As of and at all times from February 22, 2007, Fund I has been a disregarded entity for federal income tax purposes. As of and at all times from December 15, 2009, Fund II has been a disregarded entity for federal income tax purposes. As of and at all times from March 26, 2012, Fund III has been a disregarded entity for federal income tax purposes.

(30)Subchapter M. The Company qualified to be treated as a regulated investment company (“RIC”) under Subchapter M of the Code for its taxable year ended December 31, 2013, and the Company is in compliance with the requirements of the Code necessary to continue to qualify as a RIC under the Code. The Company intends to direct the investment of the net proceeds of the offering of the Securities and continue to conduct its activities in such a manner as to comply with the requirements of Subchapter M of the Code.

(31)Insurance. Each of the Company and Fund I maintain a joint directors and officers/errors and omissions insurance policy and fidelity bond that complies with the requirements of Rule 17g-1 under the 1940 Act.

(37)Statistical, Demographic or Market-Related Data. Any statistical, demographic or market-related data included in the Registration Statement, the Preliminary Prospectus or the Prospectus is based on or derived from sources that the Company believes to be reliable and accurate and all such data included in the Registration Statement, the Preliminary Prospectus or the Prospectus accurately reflects the materials upon which it is based or from which it was derived.

(39)Absence of Undisclosed Payments.

(b)Optional Securities. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to 1,050,000 Optional Securities at the Purchase Price (less the per share amount or value, as applicable, of any dividend or other distribution declared by the Company, the record date of which occurs during the period from the Closing Time through the Option Closing Time (as defined below) with respect thereto). Said option may be exercised in whole or in part at any time and from time to time on or before the 30th day after the date of the Prospectus upon notice by the Underwriters to the Company setting forth the number of shares of the Optional Securities as to which the several Underwriters are exercising the option and the settlement time and date. The number of Optional Securities to be purchased by each Underwriter shall be the same percentage of the total number of shares of the Optional Securities to be purchased by the several Underwriters as such Underwriter is purchasing of the Initial Securities, plus any additional number of Optional Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 9 hereof, subject to such adjustments as you in your absolute discretion shall make to eliminate any fractional shares. Any such time and date of delivery (an “Option Closing Time”) shall be determined by you, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time.

(c)Payment. Payment of the Purchase Price for, and delivery of certificates, if any, for the Initial Securities shall be made at the offices of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ or at such other place as shall be agreed upon by the Underwriters and the Company, at 10:00 a.m. (Eastern time) on March 3, 2017 (unless postponed in accordance with the provisions of Section 9), or such other time not later than ten business days after such date as shall be agreed upon by the Underwriters and the Company (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Optional Securities are purchased by the Underwriters, payment of the Purchase Price for, and delivery of certificates, if any, for, such Optional Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Underwriters and the Company, on each Option Closing Time as specified in the notice from the Underwriters to the Company.

Delivery of the Securities shall be made to the Underwriters for the respective accounts of the several Underwriters against payment by the several Underwriters of the Purchase Price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account designated by the Company. Delivery of the Initial Securities and the Optional Securities shall be made through the facilities of The Depository Trust Company, unless the Underwriters shall otherwise instruct. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, individually and not as a representative of the Underwriters, may (but shall not be obligated to) make payment of the Purchase Price for the Initial Securities or the Optional Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Option Closing Time, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(3)Opinion of Counsel for the Underwriters. The favorable opinion of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Underwriters, dated such Option Closing Time, relating to the Optional Securities to be purchased on such Option Closing Time and otherwise to the same effect as the opinion required by Section 5(c) hereof.

(l)Delivery of Documents. The documents required to be delivered by this Section 5 shall be delivered at the office of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, on the Closing Time and at each Option Closing Time.

Section 6.Indemnity and Contribution.

(a)The Company agrees to indemnify and hold harmless each Underwriter, its partners, directors, officers and employees, and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act and each affiliate of any Underwriter within the meaning of Rule 405 under the 1933 Act who has participated or alleged to have participated in the distribution of the Securities from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Disclosure Package or any amendment or supplement thereto, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the 1933 Act, any “road show” as defined in Rule 433(h) under the 1933 Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein.

(b)Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Disclosure Package, road show, or the Prospectus or any amendment or supplement thereto.

(c)In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 6(a) or 6(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, in the case of parties indemnified pursuant to Section 6, and by the Company, in the case of parties indemnified pursuant to Section 6(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there

be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d)To the extent the indemnification provided for in Section 6(a) or 6(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause 6(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 6(d)(i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective number of Securities they have purchased hereunder, and not joint.

(e)The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 6(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. No person shall be entitled to indemnification hereunder in contravention of Section 17(i) of the 1940 Act. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

Section 7.Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and covenants contained in this Agreement or in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on

behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company, and shall survive the acceptance of and payment for any of the Securities.

Section 8.Termination of Agreement. (a) The Underwriters may terminate this Agreement, by notice to the Company, at any time on or prior to the Closing Time (and, if any Optional Securities are to be purchased on an Option Closing Time which occurs after the Closing Time, the Underwriters may terminate their obligations to purchase such Optional Securities, by notice to the Company, at any time on or prior to such Option Closing Time) (i) if there has been, since the respective dates as of which information is given in the Preliminary Prospectus or the Prospectus, any Material Adverse Effect, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof, any calamity or crisis, any acts of terrorism, or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is so material and adverse as to make it, in the judgment of the Underwriters, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the NYSE MKT LLC, the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either Federal or New York authorities.

(b) If this Agreement is terminated pursuant to this Section 8, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 4, 6, 7, 11, 14 and 17 hereof shall survive such termination and remain in full force and effect.

Section 9.Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or an Option Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the remaining Underwriters shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Underwriters shall not have completed such arrangements within such 24-hour period, then:

(a)if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(b)if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Option Closing Time which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Company to sell the Optional Securities to be purchased and sold on such Option Closing Time, shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 9 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of an Option Closing Time which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Optional Securities, as the case may be, either the Underwriters or the Company shall have the right to postpone the Closing Time or the relevant Option Closing Time, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 9.

Section 10.Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of

Re: Lock-Up Agreement for shares of Triangle Capital Corporation

Ladies and Gentlemen:

The undersigned understands that ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (“▇▇▇▇▇▇ ▇▇▇▇▇▇▇”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Triangle Capital Corporation, a Maryland corporation (the “Company”), providing for the public offering (the “Public Offering”) of 7,000,000 shares (the “Shares”) of common stock, par value $0.001 per share, of the Company (the “Common Stock”). ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ is acting as representative of the several underwriters named in Schedule A to the Underwriting Agreement (the “Underwriters”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 30 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions; or (b) transfers of shares of Common Stock or any security convertible into Common Stock as a bona fide gift; or (c) distributions of shares of Common Stock or any security convertible into Common Stock to limited partners or stockholders of the undersigned, provided that in the case of any transfer or distribution pursuant to clause (b) or (c), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the restricted period referred to in the foregoing sentence; or (d) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock, provided that such plan does not provide for the transfer of Common Stock during the restricted period and no public announcement or filing under the Exchange Act regarding the establishment of such plan shall be required of or voluntarily made by or on behalf of the undersigned or the Company; or (e) Common Stock, withheld by, or transferred to the Company under any Restricted Stock Award Agreement for purposes of covering any tax withholding obligations on behalf of the undersigned, as permitted under the Company's Amended and Restated 2007 Equity Incentive Plan; or (f) the issuance of shares of Common Stock issuable under the Company's dividend reinvestment plan. In addition, the undersigned agrees that, without the prior written consent of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ on behalf of the Underwriters, it will not, during the period

commencing on the date hereof and ending 30 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent and registrar against the transfer of the undersigned's shares of Common Stock except in compliance with the foregoing restrictions.
