Ladies and Gentlemen:

Gladstone Capital Corporation, a Maryland corporation (the “Company”), Gladstone Management Corporation, a Delaware corporation (the “Adviser”), and Gladstone Administration, LLC, a Delaware limited liability company (the “Administrator”), each confirms with Raymond James & Associates, Inc. and each of the other underwriters named in Exhibit A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as provided in Section 8 hereof), for whom Raymond James & Associates, Inc. is acting as the representative (in such capacity, the “Representative”) with respect to the issuance and sale by the Company of $50,000,000 aggregate principal amount of the Company’s 5.125% notes due 2026 (the “Securities”), and the purchase by the Underwriters, acting severally and not jointly, of the aggregate principal amount of Securities set forth opposite their respective names in Exhibit A hereto. In the event that only one Underwriter is listed in Exhibit A hereto, any references to the “Underwriters” shall be deemed to refer to the sole Underwriter in the singular form listed in such Exhibit A to this Agreement.

The Company has entered into a second amended and restated investment advisory and management agreement, dated April 14, 2020 (the “Investment Advisory Agreement”), with the Adviser. The Company has entered into an administration agreement, dated as of October 1, 2006 (the “Administration Agreement”), with the Administrator.

The Company has filed, pursuant to the Securities Act of 1933, as amended (collectively with the rules and regulations of the Commission promulgated thereunder, the “1933 Act”), with the U.S. Securities and Exchange Commission (the “Commission”) a universal shelf registration statement on Form N-2 (File No. 333-228720), which registers the offer and sale of certain securities to be issued from time to time by the Company, including the Securities. The registration statement as amended as of its most recent effective date, including the exhibits and schedules thereto, all documents incorporated or deemed to be incorporated in the registration statement by reference, any information contained in a prospectus supplement relating to the Securities subsequently filed with the Commission pursuant to Rule 424 (“Rule 424”) under the 1933 Act and deemed to be a part of the registration statement at the time of effectiveness pursuant to Rule 430B (“Rule 430B”) under the 1933 Act, any registration statement filed pursuant to Rule 462(b) under the 1933 Act (“Rule 462(b)”), and any post-effective amendment thereto, is hereinafter referred to as the “Registration Statement.”

The base prospectus included in the Registration Statement as of its most recent effective date, including documents incorporated or deemed to be incorporated therein by reference, is hereinafter referred to as the “Base Prospectus.” The preliminary prospectus supplement, dated March 5, 2021, relating to the Securities that was used prior to the execution and delivery of this Agreement and filed pursuant to Rule 424, including documents incorporated or deemed to be incorporated therein by reference, is herein called the “Preliminary Prospectus Supplement.” The Base Prospectus and the Preliminary Prospectus Supplement are referred to collectively as the “Preliminary Prospectus.” The Company will file with the Commission, in accordance with Rule 424, a final prospectus supplement, including documents incorporated or deemed to be incorporated therein by reference (the “Final Prospectus Supplement”), supplementing the Base Prospectus in connection with the offer and sale of the Securities. The Base Prospectus and Final Prospectus Supplement are hereinafter referred to collectively as the “Prospectus.” Any reference herein to the Registration Statement, the Base Prospectus, the Preliminary Prospectus Supplement, the Preliminary Prospectus, the Final Prospectus Supplement or the Prospectus shall be deemed to refer to and include any supplements or amendments thereto, filed with the Commission after the date of filing of the Prospectus under Rule 424 and prior to the termination of the offering of the Securities by the Underwriters. All references in this Agreement to financial statements and schedules and other information which is “included” or “stated” in the Registration Statement, the Preliminary Prospectus or the Prospectus (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in or otherwise deemed to be a part of or included in (whether under the Small Business Credit Availability Act (the “SBCAA”) or otherwise) the Registration Statement, the Preliminary Prospectus, or the Prospectus, as the case may be, as of any specified date; and all references in this Agreement to amendments or supplements to the Registration Statement, the Preliminary Prospectus, or the Prospectus, including those made pursuant to Rule 424 or such other rule under the 1933 Act as may be applicable to the Company, shall be deemed to mean and include, without limitation, the filing of any document under the Exchange Act (as defined below) which is or is deemed to be incorporated by reference in or otherwise deemed under the SBCAA or the rules of the Commission promulgated thereunder or otherwise to be a part of or included in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be, as of any specified date.

The Securities will be issued under an indenture, dated as of November 6, 2018 (the “Base Indenture”), as supplemented by a third supplemental indenture (the “Third Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of December 15, 2020, between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Securities will be issued to Cede & Co. (or such other name as may be requested by an authorized representative of The Depository Trust Company (“DTC”)) as nominee of DTC pursuant to a blanket letter of representations (the “DTC Agreement”) between the Company and DTC. The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Underwriters deem advisable after this Agreement has been executed and delivered.

The Company has previously issued $100.0 million in aggregate principal amount of its 5.125% notes due 2026 under the Indenture (the “Existing Securities”). The Securities that will be issued and sold by the Company pursuant to this Agreement will constitute an issuance of “Additional Notes” under and as defined in the Indenture. Except as otherwise described in the Prospectus and communicated orally to the purchasers of the Securities prior to the execution and delivery of this Agreement, the Securities offered and sold by the Company pursuant to this Agreement will have identical terms to the Existing Securities, and the Securities and the Existing Securities will be treated as a single class and series of debt securities for all purposes under the Indenture.

All references in this Agreement to the Registration Statement, the Prospectus or any amendments or supplements to any of the foregoing shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (EDGAR).

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereby agree as follows:

1. Representations and Warranties of the Company, the Adviser and the Administrator. The Company, the Adviser and the Administrator, jointly and severally, represent and warrant to and agree with the Underwriters as of the date of this Agreement, as of the Applicable Time (as defined below) and as of the Closing Date (as such terms are defined in Sections 1(a) and 3(b), respectively, hereof), as follows:

(a) A registration statement on Form N-2 (File No. 333-228720) with respect to the Securities has been prepared by the Company in conformity with the requirements of the 1933 Act, has been filed with the Commission and initially became effective on February 5, 2019 in accordance with Section 8(a) of the 1933 Act. The Company meets the requirements of and complies with the conditions for the use of Form N-2 under the 1933 Act. Copies of the Registration Statement, including any amendments thereto, the preliminary prospectuses (meeting the requirements of the 1933 Act) contained therein and the exhibits, financial statements and schedules, as finally amended and revised, have heretofore been delivered by the Company to the Representative. As of the Applicable Time, the Base Prospectus and the Preliminary Prospectus Supplement and the information included in Exhibit B hereto, all considered together (collectively, the “General Disclosure Package”), did not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the General Disclosure Package or the Registration Statement in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Underwriters through the Representative, specifically for use therein, it being understood and agreed that the only such information is that described in Section 7(a) herein. As of the date set forth on its cover page (solely in the case of the Prospectus) and the Closing Date, the General Disclosure Package and the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the Registration Statement, the General Disclosure Package or the Prospectus in reliance upon, and in conformity with, written information furnished by or on behalf of any Underwriters through the Representative, specifically for use therein, it being understood and agreed that the only such information is that described in Section 7(a) herein. As used in this subsection and elsewhere in this Agreement, the term “Applicable Time” means 12:15 p.m. (New York time) on the date of this Agreement or such other time as agreed to by the Company and the Representative.

The Commission has not issued an order preventing or suspending the use of the Base Prospectus, the Preliminary Prospectus Supplement or the Prospectus relating to the proposed offering of the Securities, and no proceeding for that purpose or pursuant to Section 8A of the 1933 Act has been instituted or, to the Company’s knowledge, threatened by the Commission. The Registration Statement and Preliminary Prospectus each contains, and the Prospectus and any amendments or supplements thereto contain and will contain, all statements which are required to be stated therein by, and conform and will conform to the requirements of, the 1933 Act. At the respective times the Registration Statement and any post-effective amendments thereto became effective and as of the Applicable Time and the Closing Date, the Registration Statement did not, and will not, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the

statements therein not misleading; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the Registration Statement and the Prospectus, or any such amendment or supplement, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of any Underwriters through the Representative, specifically for use therein, it being understood and agreed that the only such information is that described in Section 7(a) herein.

(b) The Company (including its agents and representatives, other than the Underwriters in their capacity as such) has not made and will not, without the prior consent of the Representative, make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the 1933 Act and which the parties agree, for the purposes of this Agreement, includes (i) any “advertisement” as defined in Rule 482 under the 1933 Act; (ii) any document not constituting a prospectus pursuant to Section 2(a)(10)(a) of the 1933 Act or Rule 134 under the 1933 Act; and (iii) any Sales Material (as defined below).

(c) The documents (other than exhibits) incorporated by reference in each of the Registration Statement, the Preliminary Prospectus, and the Prospectus, when they were filed with the Commission conformed in all material respects to the requirements of the Securities Exchange Act of 1934, as amended (collectively with the rules and regulations of the Commission promulgated thereunder, the “Exchange Act”), and none of such documents contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and any further documents (other than exhibits) so filed and incorporated by reference in the Registration Statement, the Preliminary Prospectus Supplement, and the Prospectus, when such documents are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Exchange Act and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Maryland, with corporate power and authority to own or lease its properties and conduct its business as currently carried on and described in the Registration Statement, the General Disclosure Package and the Prospectus and to enter into and perform its obligations under this Agreement, the Indenture, the Securities and the DTC Agreement, except where the failure of the Company to be so qualified or in good standing or have such power or authority would not result in a Company Material Adverse Effect (defined below). Each of the Company’s consolidated subsidiaries other than those entities which would not constitute a “significant subsidiary” within the meaning of Rule 1-02(w) of Regulation S-X are listed on Schedule B hereto (each, a “Subsidiary” and collectively, the “Subsidiaries”). Each of the Subsidiaries has been duly organized and is validly existing as a limited liability company or corporation, as applicable, in good standing under the laws of its jurisdiction of organization, with all requisite power and authority to own or lease its properties and conduct its business as currently carried on and described in the Registration Statement, the General Disclosure Package and the Prospectus, except where the Subsidiaries’ failure to be so qualified would not (i) have, individually or in the aggregate, a material adverse effect on the earnings, business, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and the Subsidiaries, taken as a whole, or (ii) prevent the consummation of the transactions contemplated hereby and under the Indenture and/or the Securities (the occurrence of any such effect or any such prevention described in the foregoing clauses (i) and (ii) being referred to as a “Company Material Adverse Effect”). Each of the Company and each of the Subsidiaries is duly qualified to transact business in all jurisdictions in which the conduct of its business requires such qualification, except for such jurisdictions where failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a Company Material Adverse Effect. The outstanding shares of capital stock of each

of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are wholly owned by the Company or another Subsidiary free and clear of all liens, encumbrances and equities and claims; and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into shares of capital stock or ownership interests in the Subsidiaries are outstanding. The Company does not own, directly or indirectly, any shares of stock or any other equity or long-term debt securities of any corporation or other entity other than (x) Gladstone Business Loan, LLC, a Delaware limited liability company, and (y) those corporations or other entities accounted for as portfolio investments in accordance with the Commission’s rules and regulations (each, a “Portfolio Company,” and collectively, the “Portfolio Companies”). Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, as of the respective dates set forth therein, the Company does not control (as such term is defined in Section 2(a)(9) of the Investment Company Act of 1940, as amended (collectively with the rules and regulations of the Commission promulgated thereunder, the “1940 Act”)) any of the Portfolio Companies.

(e) The authorized, issued and outstanding capital stock of the Company is as set forth in the Prospectus and the General Disclosure Package as of the date thereof under the caption “Capitalization.” The outstanding shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) have been duly authorized and validly issued and are fully paid and non-assessable. None of the outstanding shares of Common Stock was issued in violation of the preemptive or other similar rights of any security holder of the Company, nor does any person have any preemptive right of first refusal or other right to acquire any of the Securities covered by this Agreement. Neither the filing of the Registration Statement nor the offering or sale of the Securities as contemplated by this Agreement gives rise to any rights, other than those which have been waived or satisfied, for or relating to the registration of any class of securities of the Company.

(f) The information set forth under the captions “Description of Our Securities” and “Description of the Notes” in the Registration Statement, the General Disclosure Package and the Prospectus, insofar as such statements purport to summarize certain provisions of the 1940 Act, Maryland law, the Indenture and the Securities, fairly and accurately summarize such provisions in all material respects. The Indenture and the Securities materially conform to the description thereof contained in the Registration Statement, the General Disclosure Package and the Prospectus. The form of certificate for the Securities conform to the requirements of the Indenture and any requirements of the Company’s charter or bylaws. Subsequent to the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus, except as otherwise specifically stated therein or in this Agreement or as would not reasonably be expected to result in a Company Material Adverse Effect, the Company has not: (i) issued any securities or incurred any liability or obligation, direct or contingent, for borrowed money; or (ii) declared or paid any dividend or made any other distribution on or in respect to its capital stock.

(g) The Company has duly authorized, executed and delivered and currently is a party to or payee with respect to the promissory notes and other agreements evidencing its investments in the Portfolio Companies (each, a “Portfolio Company Agreement”). Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, to the Company’s knowledge, each Portfolio Company is current with all its obligations under the applicable Portfolio Company Agreements and no event of default (or a default which with the giving of notice or the passage of time would become an event of default) has occurred under such agreements, except to the extent that any such failure to be current in its obligations and any such default would not reasonably be expected to result in a Company Material Adverse Effect.

(h) The Base Indenture has been duly authorized, executed and delivered by the Company and constitutes a legal, valid and binding agreement of the Company enforceable in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, and by general equitable principles.

(i) The Third Supplemental Indenture has been duly authorized, executed and delivered by the Company and constitutes a legal, valid and binding agreement of the Company enforceable in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, and by general equitable principles.

(j) The Securities have been duly authorized by the Company for sale to the Underwriters pursuant to this Agreement and, when executed and delivered by the Company and authenticated by the Trustee pursuant to the provisions of the Indenture relating thereto, against payment of the consideration set forth in this Agreement, will constitute legal, valid and binding agreements of the Company enforceable in accordance with their terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, and by general equitable principles.

(k) The DTC Agreement has been duly authorized, executed and delivered by the Company and constitutes a legal, valid and binding agreement of the Company enforceable in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, and by general equitable principles.

(l) The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

(m) The Company has not, directly or indirectly, distributed and will not distribute, without the prior written consent of the Representative, any offering material in connection with the offering and sale of the Securities other than the Registration Statement, the General Disclosure Package, the Prospectus and the Sales Material.

(n) The consolidated financial statements of the Company and the Subsidiaries, together with related notes and schedules as set forth or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, present fairly in all material respects the consolidated financial position and the results of operations and cash flows of the Company and the Subsidiaries, as of the indicated dates and for the indicated periods. Such financial statements and related schedules have been prepared in accordance with generally accepted principles of accounting in the United States (“GAAP”), consistently applied throughout the periods involved, except as disclosed therein, and all adjustments necessary for a fair presentation of results for such periods have been made. The summary and selected consolidated financial and statistical data included in the Registration Statement, the General Disclosure Package and the Prospectus present fairly the information shown therein, and such data have been compiled on a basis consistent with the financial statements presented therein and the books and records of the Company. All disclosures contained in the Registration Statement, the General Disclosure Package and the Prospectus regarding “non-GAAP financial measures” (as such term is defined by the 1933 Act) comply with Regulation G under the Exchange Act, and Item 10 of Regulation S-K under the 1933 Act, to the extent applicable. The Company and the Subsidiaries do not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations or any “variable interest entities” within the meaning of the Financial Accounting Standards Board’s Accounting Standards Codification Topic 810), which are not disclosed in the Registration Statement, the General Disclosure Package and the Prospectus. There are no financial statements (historical or pro forma) that are required to be included in the Registration Statement or the Prospectus that are not included as required.

(o) Any audited consolidated financial statements of a Portfolio Company, together with related notes and schedules, included in the Registration Statement, the General Disclosure Package and the Prospectus, present fairly in all material respects the financial position and the results of operations and cash flows of such Portfolio Company, as of the indicated dates and for the indicated periods. Such audited consolidated financial statements and related schedules have been prepared in accordance with GAAP, consistently applied throughout the periods involved, except as disclosed therein.

(p) PricewaterhouseCoopers, LLP, who has audited and certified certain of the financial statements incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, and whose reports with respect to the financial statements of the Company and its Subsidiaries are incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, is an independent registered public accounting firm with respect to the Company and the Subsidiaries within the meaning of the 1933 Act, the Exchange Act and the Public Company Accounting Oversight Board (United States).

(q) The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act). The Company’s internal control over financial reporting is effective and, except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, neither the Company nor any of the Subsidiaries is aware of (i) any material weakness in its internal control over financial reporting or (ii) any change in internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(r) Solely to the extent that the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations promulgated by the Commission and the Nasdaq Global Select Market (“Nasdaq”) thereunder (collectively, the “Sarbanes-Oxley Act”) have been applicable to the Company, there is and has been no failure on the part of the Company to comply with any applicable provision of the Sarbanes-Oxley Act that would reasonably be expected, individually or in the aggregate, to have a Company Material Adverse Effect.

(s) There is no action, suit, claim or proceeding pending or, to the Company’s knowledge, threatened against the Company or any of the Subsidiaries before any court or administrative agency or otherwise, which if determined adversely to the Company or any of the Subsidiaries would reasonably be expected, individually or in the aggregate, to have a Company Material Adverse Effect, except as set forth in the Registration Statement, the General Disclosure Package and the Prospectus.

(t) The Company and the Subsidiaries have good and marketable title to all of the properties and assets reflected in the consolidated financial statements hereinabove described or described in the Registration Statement, the General Disclosure Package and the Prospectus, subject to no lien, mortgage, pledge, charge or encumbrance of any kind, except those reflected in such financial statements or described in the Registration Statement, the General Disclosure Package and the Prospectus or which are not material in amount. Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, the Company and the Subsidiaries are not party to any leases, except for such leases entered into after the effective date of the Prospectus and such leases that would not be reasonably likely to result in a Company Material Adverse Effect.

(u) The Company and the Subsidiaries have filed all federal, state, local and foreign tax returns which have been required to be filed and have paid all taxes indicated by such returns and all assessments received by them or any of them to the extent that such taxes have become due and are not being contested in good faith and for which an adequate reserve for accrual has been established in accordance with GAAP, other than as set forth or contemplated in the Registration Statement, the General

Disclosure Package and the Prospectus, and except where the failure to so file or pay would not have a Company Material Adverse Effect. All tax liabilities have been adequately provided for in the financial statements of the Company, and the Company does not know of any actual or proposed additional material tax assessments.

(v) Since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus, there has not been (i) any material adverse change or any development that is reasonably likely, either individually or in the aggregate, to involve a prospective material adverse change in the earnings, business, management, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and the Subsidiaries taken as a whole, whether or not occurring in the ordinary course of business; (ii) any material transaction entered into, or any material transaction that is probable of being entered into, by the Company or the Subsidiaries, other than transactions in the ordinary course of business and changes and transactions described in the Registration Statement, the General Disclosure Package and the Prospectus, as amended or supplemented; and (iii) except for regular distributions paid or declared by the Company to its stockholders consistent with past practice or any other distributions described in the General Disclosure Package and the Prospectus, there has been no dividend or distribution of any kind declared, paid or made by the Company. The Company and the Subsidiaries have no material contingent obligations which are not disclosed in the Company’s financial statements which are included in the Registration Statement, the General Disclosure Package and the Prospectus.

(w) Neither the Company nor any of the Subsidiaries is or, with the giving of notice or lapse of time or both, will be as of the Applicable Time and/or the Closing Date: (i) in violation of its charter or certificate or articles of incorporation (as amended, restated and supplemented), bylaws, certificate of formation, limited liability company agreement, partnership agreement or other organizational documents, (ii) in violation of or in default under any agreement, lease, contract, indenture or other instrument or obligation to which it is a party or by which it, or any of its properties, is bound or (iii) in violation of any law, order, rule or regulation, judgment, order, writ or decree applicable to the Company or any Subsidiary of any court or of any government, regulatory body or administrative agency or other governmental body having jurisdiction over the Company or such Subsidiary or any of its properties, as applicable, and, solely with respect to clauses (ii) and (iii), which violation or default would have a Company Material Adverse Effect. The execution, delivery and performance of this Agreement, the Indenture, the Securities, the DTC Agreement and the consummation of the transactions contemplated hereby and thereby (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 the fulfillment of the terms hereof and thereof will not conflict with or result in a breach of (x) any of the terms or provisions of, or constitute a breach of or default or Repayment Event (as defined below) under, any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any Subsidiary is a party or by which the Company or any Subsidiary or any of their respective properties is bound or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its Subsidiaries pursuant to the terms of any such indenture, mortgage, deed of trust or other agreement or instrument, (y) the charter or bylaws of the Company or (z) any law, order, rule or regulation, judgment, order, writ or decree applicable to the Company or any Subsidiary of any court or of any government, regulatory body or administrative agency or other governmental body having jurisdiction over the Company or such Subsidiary or any of its properties, as applicable, except with respect to clauses (x) and (z) for such conflicts, breaches, defaults or violations as would not, individually or in the aggregate, have a Company 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 the Company or any of its Subsidiaries, as applicable.

(x) The execution and delivery of, and the performance by the Company, the Adviser and the Administrator of their obligations under, this Agreement have been duly and validly authorized by all necessary corporate action or limited liability company action, as applicable, on the part of the Company, the Adviser and the Administrator, and this Agreement has been duly executed and delivered by the Company, the Adviser and the Administrator.

(y) Each approval, consent, order, authorization, designation, declaration or filing by or with any regulatory, administrative or other governmental body necessary in connection with the execution, delivery and performance by the Company of this Agreement, the Indenture, the Securities and the DTC Agreement and the consummation of the transactions contemplated hereby and thereby and by the Prospectus and the General Disclosure Package (including the use of the proceeds from the sale of the Securities as described in the General Disclosure Package and the Prospectus under the caption “Use of Proceeds”) has been obtained or made and is in full force and effect, except (i) the Current Report on Form 8-K adding certain documents related to the offering of the Securities as exhibits to the Registration Statement and (ii) such additional steps as may be necessary to qualify the Securities for public offering by the Underwriters under state securities or Blue Sky laws.

(z) The Company, the Adviser, the Administrator and each of the Subsidiaries hold all licenses, certificates and permits from governmental authorities which are necessary to the conduct of their businesses as described in the Registration Statement, the General Disclosure Package and the Prospectus, except where the failure to hold such licenses, certificates or permits would not have a Company Material Adverse Effect; the Company, the Adviser, the Administrator and the Subsidiaries each own or possess rights to use all patents, patent rights, trademarks, trade names, service marks, service names, copyrights, license rights, know-how (including trade secrets and other unpatented and unpatentable proprietary or confidential information, systems or procedures) and other intellectual property rights (“Intellectual Property”) necessary to carry on their businesses as described in the Registration Statement, the General Disclosure Package and the Prospectus in all material respects; none of the Company, the Adviser, the Administrator or any of the Subsidiaries has infringed, and none of the Company, the Adviser, the Administrator or the Subsidiaries has received notice of conflict with, any Intellectual Property of any other person or entity. None of the technology employed by the Company, the Adviser or the Administrator has been obtained or is being used by the Company, the Adviser or the Administrator in violation of any contractual obligation binding on the Company, the Adviser, the Administrator or any of their respective officers, directors or employees or otherwise in violation of the rights of any persons; none of the Company, the Adviser or the Administrator has received any written or oral communications alleging that the Company has violated, infringed or conflicted with, or, by conducting its business as set forth in the Registration Statement, the General Disclosure Package and the Prospectus, would violate, infringe or conflict with, any of the Intellectual Property of any other person or entity, except for such violations, infringements or conflicts that would not have a Company Material Adverse Effect. Except as disclosed in the Registration Statement and the Prospectus and except as would not reasonably be expected, individually or in the aggregate, to result in a Company Material Adverse Effect, none of the Company, the Adviser or the Administrator knows of any infringement by others of Intellectual Property owned by or licensed to the Company, the Adviser or the Administrator.

(aa) Neither the Company, nor to the Company’s knowledge, any of its affiliates, has taken or will take, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of the Securities to facilitate the sale or resale of the Securities.

(bb) The terms of the Investment Advisory Agreement and the Administration Agreement, including compensation terms, comply in all material respects with all applicable provisions of the 1940 Act and the Investment Advisers Act of 1940, as amended (collectively with the rules and regulations of the Commission promulgated thereunder, the “Advisers Act”), and the approvals by the board of directors and the Company’s stockholders, as applicable, of the Investment Advisory Agreement have been obtained in accordance with the requirements of Section 15 of the 1940 Act applicable to companies that have elected to be regulated as business development companies under the 1940 Act.

The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T, or as filed with the Commission in paper form as permitted by Regulation S-T.

(d) The Company has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under

the 1933 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e) The Company will use its commercially reasonable efforts to comply with the 1933 Act so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act, the Company will promptly prepare and file with the Commission, subject to Section 5(b) of this Agreement, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) The Company will cooperate with the Representative in endeavoring to qualify the Securities for offering and sale under the applicable securities laws of such jurisdictions (domestic or foreign) as the Representative may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose; provided the Company will not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representative may reasonably request for distribution of the Securities.

(g) The Company will make generally available to its security holders, as soon as it is practicable to do so, an earnings statement or statements (which need not be audited), which will satisfy the requirements of Section 11(a) of the 1933 Act and Rule 158 under the 1933 Act and will advise the Representative in writing when such statement has been so made available.

(h) No offering, sale, short sale or other disposition of any debt securities issued or guaranteed by the Company or other securities convertible into or exchangeable or exercisable for debt securities issued or guaranteed by the Company or derivative of debt securities issued or guaranteed by the Company (or agreement for such) will be made for a period of 90 days after the date of the Prospectus, directly or indirectly, by the Company otherwise than hereunder or with the prior written consent of the Representative.

(i) The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the General Disclosure Package and in the Prospectus under “Use of Proceeds.”

(j) The Company will cooperate with the Representative and use its commercially reasonable efforts to permit the offered Securities to be eligible for clearance and settlement through the facilities of DTC.

(k) The Company will maintain a trustee, paying agent and registrar for the Securities.

(l) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Securities, except as may be allowed by law.

(m) The Company, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1933 Act, the Exchange Act and the 1940 Act within the time periods required by such act, rule or regulation. To the extent the distribution of Securities has been completed, the Company will not be required to provide the Underwriters with reports it is required to file with the Commission under the Exchange Act.

(n) The Company, during a period of at least 12 months from the Closing Date, will use its commercially reasonable efforts to maintain its status as a business development company.

(o) During the 12-month period following the Closing Date, the Company will use its commercially reasonable efforts to qualify and elect to be treated as a regulated investment company under Subchapter M of the Code and to maintain such qualification and election in effect for each full fiscal year during which it is a business development company under the 1940 Act.

(p) The Company will use its commercially reasonable efforts to maintain a system of internal accounting controls sufficient to provide reasonable assurances that (A) material information relating to the Company and the assets managed by the Adviser is promptly made known to the officers responsible for establishing and maintaining the system of internal accounting controls; and (B) any significant deficiencies or weaknesses in the design or operation of internal accounting controls which could adversely affect the Company’s ability to record, process, summarize and report financial data, and any fraud whether or not material that involves management or other employees who have a significant role in internal controls, are adequately and promptly disclosed to the Company’s independent auditors and the audit committee of the Company’s board of directors.

6. Conditions to the Underwriters’ Obligations. The obligations of the Underwriters to purchase the Securities on the Closing Date are subject to the accuracy, as of the Applicable Time or the Closing Date, as the case may be, of the representations and warranties of the Company, the Adviser and the Administrator contained herein, and to the performance by the Company of its covenants and obligations hereunder and to the following additional conditions:

(a) The Registration Statement and all post-effective amendments thereto, including any filing under Rule 462(b), shall have become effective, the final prospectus containing the information that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement pursuant to Rule 430B shall have been filed with the Commission in accordance with Rule 424(b), and any request of the Commission for additional information (to be included in the Registration Statement or otherwise) shall have been disclosed to the Representative and complied with to its reasonable satisfaction. No stop order suspending the effectiveness of the Registration Statement, as amended from time to time, shall have been issued and no proceedings for that purpose or pursuant to Section 8A under the 1933 Act shall have been taken or, to the knowledge of the Company, shall be contemplated or threatened by the Commission and no injunction, restraining order or order of any nature by a Federal or state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance of the Securities.

(b) The Representative shall have received from Proskauer Rose LLP, counsel for the Company (“Company Counsel”), an opinion and a negative assurance letter, each dated the Closing Date, addressed to the Representative in form and substance reasonably satisfactory to the Representative.

(c) The Representative shall have received from Venable LLP, special Maryland counsel for the Company (“Maryland Counsel”), an opinion dated the Closing Date, addressed to the Underwriters, regarding matters relating to Maryland law, in form and substance reasonably satisfactory to the Representative.

(d) The Representative shall have received from Dechert LLP, counsel to Underwriters (“Underwriters’ Counsel”), an opinion and negative assurance letter dated the Closing Date, addressed to the Underwriters, in form and substance reasonably satisfactory to the Representative.

(e) The Representative shall have received, on each of the date hereof and the Closing Date, the letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Representative, of PricewaterhouseCoopers, LLP, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters, delivered in accordance with Statement of Auditing Standards No. 72 (or any successor bulletin), with respect to the financial statements and certain financial and statistical information contained in the Registration Statement, the General Disclosure Package and the Prospectus.

(f) The Representative shall have received, on each of the date hereof and the Closing Date, a certificate of the chief financial officer of the Company, in form and substance reasonably satisfactory to the Representative and as agreed upon prior to the date hereof, covering certain financial matters of the Company.

(g) Each of the Company, the Adviser and the Administrator shall have furnished to the Representative, on the Closing Date, a certificate substantially in the form of Exhibit 6(g).

(h) The Company and the Trustee shall have executed and delivered each of the Base Indenture, the Third Supplemental Indenture and the Securities and, at or prior to the Closing Date, the Indenture shall be in full force and effect.

(i) Each of the Company, the Adviser and the Administrator shall have furnished to the Representative such further certificates and documents as the Representative may reasonably require for the purpose of enabling the Underwriters to pass upon the issuance and sale of the Securities as herein contemplated.

(j) At the Closing Date, the Securities shall be rated at least A- by Egan-Jones Ratings Company and since the execution of this Agreement, there shall not have been any decrease in the rating of any debt or preferred stock of the Company or any Subsidiary by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the Exchange Act), or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change, and no such organization shall have publicly announced it has under surveillance or review any such rating.

The opinions and certificates mentioned in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects satisfactory to the Representative and to Underwriters’ Counsel.

If any of the conditions hereinabove provided for in this Section 6 shall not have been fulfilled when and as required by this Agreement to be fulfilled, the obligations of the Underwriters hereunder may be terminated by the Representative by notifying the Company of such termination in writing at or prior to the Closing Date. In such event, the Company and the Underwriters shall not be under any obligation to each other (except to the extent provided in Sections 4, 7 and 10 hereof).

7. Indemnification and Contribution.

(a) The Company, the Adviser and the Administrator, jointly and severally, agree to indemnify and hold harmless the Underwriters, the directors, officers, employees and agents of the Underwriters and each person who controls the Underwriters within the meaning of either Section 15 of the 1933 Act or Section 20 of the Exchange Act:

(i) against any and all loss, liability, claim, damage and expense whatsoever, arising out of any untrue or alleged untrue statement of a material fact contained in the Registration Statement for the Securities as originally filed or in any amendment thereof (and including any post-effective amendment), the General Disclosure Package or the Prospectus or in any Sales Material (or any amendment or supplement to any of the foregoing), or arising out of or based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representative), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under Section 7(a)(i) or (a)(ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto), or the General Disclosure Package, any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: (i) the concession figure appearing under the caption “Underwriting—Commissions and Discounts” in the Prospectus, (ii) the statement set forth in the first sentence of the first paragraph under the caption “Underwriting—Stabilization” in the Prospectus, and (iii) the list of Underwriters and their respective participation in the sale of the Securities, which is set forth in the first paragraph under the caption “Underwriting” in the Prospectus.

(b) Each Underwriter severally agrees to indemnify and hold harmless the Company, the Adviser and the Administrator, each of their respective directors, each of their respective officers who sign the Registration Statement, and each person who controls the Company, the Adviser and the Administrator within the meaning of either Section 15 of the 1933 Act or Section 20 of the Exchange Act, to the same extent as the indemnity from the Company, the Adviser and the Administrator to the Underwriters set forth in Section 7(a)(i) and the proviso thereto, but only with reference to written information relating to the Underwriters furnished to the Company by or on behalf of the Underwriters specifically for inclusion in the documents referred to in the foregoing indemnity. The Underwriters agree to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any loss, claim, damage, liability or action to which they are entitled to indemnification pursuant to this Section 7(b). This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have.

(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 7, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 7 shall be available to any party who shall fail to give notice as provided in this Section 7(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 7. In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred 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 at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (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 or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. Such firm shall be designated in writing by the Representative in the case of parties indemnified pursuant to Section 7(a) and by the Company in the case of parties indemnified pursuant to Section 7(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. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding and does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 7 is unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or (b) above in respect of any losses, liabilities, claims, damages or expenses (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such

proportion as is appropriate to reflect the relative benefits received by the Company, the Adviser and the Administrator, on the one hand, and the Underwriters, on the other, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, the Adviser or the Administrator, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company, the Adviser and the Administrator, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Adviser, the Administrator and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(d) 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 which does not take account of the equitable considerations referred to above in this Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 7(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Securities purchased by such Underwriter and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the Exchange Act and each Underwriter’s affiliates, directors, officers, and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company, and each person, if any, who controls the Company, Adviser or Administrator within the meaning of Section 15 of the 1933 Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company, Adviser or Administrator, as the case may be. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of Securities set forth opposite their respective names in Exhibit A hereto and not joint.

(f) Notwithstanding any other provision of this Section 7, no party shall be entitled to indemnification or contribution under this Agreement in violation of Section 17(i) of the 1940 Act.

8. Default by One or More Underwriters. If one or more of the Underwriters shall fail on the Closing Date to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall use reasonable efforts, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 36-hour period, then:

(a) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount 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 aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 8 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, the Representative shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package 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 8.

9. Termination.

(a) This Agreement may be terminated by the Representative by notice to the Company (a) at any time prior to the Closing Date if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the earnings, business, properties, assets, rights, operations, condition (financial or otherwise) or prospects of the Company and the Subsidiaries taken as a whole, whether or not arising in the ordinary course of business, which the Representative deems to materially impair the investment quality of the Securities, (ii) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international calamity or crisis (including, without limitation, an act of terrorism) or change in economic or political conditions, if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States would, in the judgment of the Representative, materially impair the investment quality of the Securities, (iii) suspension of trading in securities generally on the New York Stock Exchange or Nasdaq or limitation on prices (other than limitations on hours or numbers of days of trading), (iv) the declaration of a banking moratorium by United States or New York State authorities, (v) the suspension of trading of any security of the Company by Nasdaq, the Commission or any other governmental authority or (vi) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in the opinion of the Representative has a material adverse effect on the securities markets in the United States; or (b) as provided in Section 6 of this Agreement.

(b) If this Agreement is terminated pursuant to this Section 9, 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, 7 and 10 shall survive such termination and remain in full force and effect.

10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, the Adviser and the Administrator, or their respective officers, and of the Underwriters set forth in or made pursuant to this Agreement (including as may be made in certificates of officers of the Company, the Adviser and the Administrator submitted pursuant hereto) will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Securities. The provisions of Section 4, Section 7, Section 10, Section 13, Section 15 and Section 16 shall survive the termination or cancellation of this Agreement.

11. Notices. All communications hereunder will be in writing and effective only on receipt, and will be mailed (postage prepaid, certified or registered mail, return receipt requested), delivered or transmitted by any standard form of telecommunication:

* Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

** Under Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the New Notes on any date prior to the second business day before delivery thereof will be required, by virtue of the fact that the New Notes initially will settle T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the New Notes who wish to trade the New Notes prior to their date of delivery hereunder should consult their own advisors.
