NOW, THEREFORE, Investment Adviser and Sub-Adviser agree as follows:

1.	APPOINTMENT OF THE SUB-ADVISER

Investment Adviser hereby appoints Sub-Adviser to act as a sub-adviser to the Fund, and in accordance with the terms and conditions of this Agreement.

2.	ACCEPTANCE OF APPOINTMENT

Sub-Adviser accepts that appointment and agrees to render the services herein set forth, for the compensation herein provided.

The Fund’s assets will be maintained in the custody of a custodian (who shall be identified by Investment Adviser in writing). Sub-Adviser will not have custody of any securities, cash or other assets of the Fund and will not be liable for any loss resulting from any act or omission of the custodian other than acts or omissions arising in reasonable reliance on instructions of Sub-Adviser. The custodian will be responsible for the custody, receipt and delivery of securities and other assets of the Fund, and, other than as specified herein, Sub-Adviser shall have no authority, responsibility or obligation with respect to the custody, receipt or delivery of securities or other assets of the Fund. Investment Adviser shall be responsible for all custodial arrangements, including the payment of all fees and charges to the custodian.

3.	SERVICES TO BE RENDERED BY THE SUB-ADVISER

A. As sub-adviser to the Fund, Sub-Adviser will coordinate and execute the investment and reinvestment of the assets of the Fund and determine the composition of the assets of the Fund.

The Sub-Adviser (and its directors, managers, officers and employees) shall perform all services under this Agreement on a discretionary basis, subject to the general direction, supervision and control of the Investment Adviser and the Fund’s Board of Trustees, and in strict conformity with: (i) the Investment Company Act, the Advisers Act and any and all other applicable laws; (ii) the Fund’s Declaration of Trust and bylaws; (iii) any and all investment guidelines, instructions and directions provided by the Investment Adviser or the Fund; (iv) the Fund’s compliance policies, procedures and guidelines; and (v) the investment objectives, policies and restrictions set forth in the prospectus and statement of additional information contained in the Fund’s Registration Statement on Form N-2 under the Securities Act of 1933, as amended (the “Securities Act”) and the Investment Company Act, as currently in effect and as supplemented and/or amended from time to time (respectively, the “Prospectus”, the “Statement of Additional Information”, and the “Registration Statement”), as each may be modified from time to time (the documents described in (ii) through (v) above, the “Fund Documents”). Prior to the commencement of the Sub-Adviser’s services hereunder, the Investment Adviser shall provide Sub-Adviser with current copies of the Fund Documents. Investment Adviser undertakes to provide Sub-Adviser with copies or other written notice of any amendments, modifications or supplements to the Fund Documents, and Sub-Adviser will not need to comply until a copy has been provided to Sub-Adviser.

Notwithstanding anything contained herein to the contrary, should Sub-Adviser choose to utilize reverse repurchase agreement obligations, derivative instruments or other instruments or trading practices that, according to the Securities and Exchange Commission (“SEC”) or its staff, may cause senior securities concerns, the Investment Adviser acknowledges that the monitoring of the use of such instruments or trading practices for compliance with the Investment Company Act, or interpretations or modifications by the SEC, SEC staff or other authority with appropriate jurisdiction, is the responsibility of the Sub-Adviser and not the Investment Adviser. The Investment Adviser, and not the Sub-Adviser, is responsible for making recommendations to the Fund regarding, and monitoring (for purposes of Investment Company Act compliance, general market conditions and otherwise), the Fund’s use of bank borrowings (other than reverse repurchase agreements) or other similar term loans and the Fund’s issuance of preferred shares (or other “senior securities” in the form of debt or stock pursuant to Section 18 of the Investment Company Act), if any.

The Sub-Adviser shall fully cooperate with the Fund’s and the Investment Adviser’s Chief Compliance Officers, the Fund’s legal counsel, any counsel to the Fund’s trustees who are not “interested persons” of the Fund (as that term is defined under the Investment Company Act) and the Fund’s independent public accounting firm.

B. Subject to any direction from the Investment Adviser or the Fund, the Sub-Adviser is responsible for placing orders for the execution of portfolio transactions with or through or with such brokers, dealers, counterparties or banks as Sub-Adviser may select. In choosing broker-dealers, Sub-Adviser may take into account, in addition to commission costs and execution capabilities, the financial stability and reputation of the broker-dealers and the brokerage and research services (as those terms are defined in Section 28(e) of the Securities Exchange Act of 1934 (the “1934 Act”)) provided by such broker-dealers. In addition, Sub-Adviser may receive brokerage and research services in connection with certain riskless principal transactions, in accordance with applicable law. Sub-Adviser is authorized to pay broker-dealers who provide such brokerage or research services a commission (or equivalent) for executing a transaction which is in excess of the commissions (or equivalents) another broker-dealer would have charged for executing that transaction, if Sub-Adviser determines that such commission (or equivalent) is reasonable in relation to the value of the brokerage and research services provided to Sub-Adviser by the broker-dealer. Sub-Adviser will use its best efforts to obtain best execution under the circumstances for all portfolio transactions for the Fund and will use its best judgment to choose the broker-dealer most capable of providing the services necessary to obtain most favorable execution under the circumstances, taking into consideration the full range and quality of a broker-dealer’s services in placing transactions with broker-dealers including, among other things, the value of research provided (with respect to evaluating commissions and commission equivalents) as well as execution capability, commission rate (or commission equivalent), financial stability and responsibility, reputation, and responsiveness to the Sub-Adviser. In no event shall Sub-Adviser be under any duty to obtain the lowest commission for the Fund on any particular transaction. Sub-Adviser is not under any duty to execute transactions for the Fund before or after transactions for other like accounts managed by Sub-Adviser, except to the extent that doing so would violate applicable law. Sub-Adviser may aggregate sales and purchase orders of securities or derivatives held in the Fund with similar orders being made simultaneously for other portfolios managed by Sub-Adviser if, in Sub-Adviser’s reasonable judgment, such aggregation shall result in an overall economic benefit to the Fund, taking into consideration the advantageous selling or purchase price,

brokerage commission, and other expenses. If an aggregate order is executed in parts at different prices, or two or more separate orders for two or more of Sub-Adviser’s clients are entered at approximately the same time on any day and are executed at different prices, Sub-Adviser has discretion, subject to its fiduciary duty to the Fund and its other advisory clients, to use an average price at which such securities were purchased or sold for the Fund and each of the clients for whom such orders were executed. Sub-Adviser may engage in brokerage and other securities transactions on behalf of the Fund with broker-dealer affiliates of Sub-Adviser in accordance with applicable Fund documents and applicable law.

C. The Sub-Adviser will furnish to the Investment Adviser and the Fund, from time to time and as the Investment Adviser may request, reports and other data or information on portfolio transactions and reports and other data or information on the Fund’s assets, all in such detail and in such frequency as may be requested from time to time. The Sub-Adviser will also provide the Investment Adviser and the Fund, upon the Investment Adviser’s or the Fund’s request, with economic and investment analysis and reports or other investment services normally available to institutional or other clients of the Sub-Adviser. The Sub-Adviser will make available its officers and employees to meet with the Investment Adviser and the Fund’s Board of Trustees to review the investments of the Fund, on a quarterly, or upon due notice, at a time requested by the Investment Adviser or the Fund’s Board of Trustees.

D. Investment Adviser understands and agrees that Sub-Adviser performs investment management services for various clients and may take action with respect to any of its other clients which may differ from action taken or from the timing or nature of action taken by Sub-Adviser for the Fund. Sub-Adviser’s authority hereunder shall not be impaired because of the fact that it may effect transactions with respect to securities for its own account or for the accounts of others which it manages which are identical or similar to securities to which it may effect transactions for the Fund at the same or similar times.

E. The Sub-Adviser also will promptly furnish and make available to the Fund such information concerning the Sub-Adviser and its services hereunder as the Investment Adviser or the Fund may request in the preparation of the Fund’s or the Investment Adviser’s regulatory filings, reports and other documents or in the fulfillment of its other compliance obligations. The Sub-Adviser will review draft filings, reports and other documents provided to it, and provide comments/corrections to the same on a timely basis. In addition, the Sub-Adviser will provide on a timely basis such certifications or sub-certifications as the Investment Adviser or the Fund may reasonably request in order to support and facilitate certifications required to be provided by the Investment Adviser or the Fund (or their officers) from time to time.

F. The Sub-Adviser shall promptly provide the Investment Adviser’s and the Fund’s Chief Compliance Officer (“CCO”), upon request, copies of its policies and procedures for compliance by the Sub-Adviser and the Fund with the Federal Securities Laws as defined in Rule 38a-1 under the Investment Company Act and promptly provide the CCO with copies of any material changes to those policies and procedures. The Sub-Adviser shall fully cooperate with the CCO as to facilitate the CCO’s performance of his/her responsibilities under Rule 38a-1 to review, evaluate and report to the Fund’s Board of Trustees on the operation of the Sub-Adviser’s compliance policies and procedures and shall promptly report to the CCO any “Material Compliance Matter” as defined by Rule 38a-1(e)(2). At least annually, the Sub-Adviser shall provide a certification to the CCO to the effect that the Sub-Adviser has in place and has implemented policies and procedures that are reasonably designed to ensure compliance by the Fund and the Sub-Adviser with the Federal Securities Laws.

G. The Sub-Adviser will maintain all books and records relating to investment decisions, trade orders and similar undertakings of the Sub-Adviser under this Agreement required to be maintained pursuant to the Investment Company Act and the rules and regulations promulgated thereunder with respect to transactions made by it on behalf of the Fund including, without limitation, the books and records required by Rule 31a-l under the Investment Company Act, and shall timely furnish to the Adviser all information relating to the Sub-Adviser’s services hereunder needed by the Adviser to keep such other books and records of the Fund required by Rule 31a-1 under the Investment Company Act. The Sub-Adviser will also preserve all such books and records for the periods prescribed in Rule 31a-2 under the Investment Company Act. The Sub-Adviser further agrees that all books and records maintained hereunder shall be made available to the Investment Adviser and the Fund at any time upon request, including facsimile, without delay, during any business day. Upon termination of this Agreement, the Sub-Adviser, at it expense, shall promptly upon demand, return to the Investment Adviser and the Fund any and all such records.

The Sub-Adviser shall not be required to maintain books and records that are required to be maintained by the Fund’s administrator other than as required of it by applicable laws and regulations. Sub-Adviser shall file with the SEC all forms pursuant to the 1934 Act with respect to its duties as are set forth herein.

H. The Sub-Adviser will, unless and until otherwise directed by the Investment Adviser, exercise all investor rights with respect to the Fund’s assets, including, but not limited to, voting proxies in accordance with the Sub-Adviser’s then-current proxy voting policies and procedures. The Sub-Adviser will report quarterly to the Investment Adviser and the Fund regarding such voting in a format reasonably requested by the Investment Adviser or the Fund. The Sub-Adviser represents that it has adopted and implemented written policies and procedures that are reasonably designed to ensure that the Sub-Adviser votes proxies in the best interest of the Fund in compliance with the requirements of Rule 206(4)-6 under the Advisers Act. The Sub-Adviser shall promptly provide notice and copies of any material changes to its policies procedures or other guidelines for voting proxies to the Fund and the Investment Adviser. Upon request, the Sub-Adviser shall provide the Investment Adviser and the Fund with a complete and current copy of its policies, procedures and other guidelines or a description of the same for the purpose of disclosing such information in the Fund’s prospectus or as otherwise required by applicable law.

The Sub-Adviser will promptly inform and forward to the Investment Adviser any and all information received by Sub-Adviser relating to any class action or other litigation, any bankruptcy matters, or any other legal proceedings involving the Fund’s portfolio investments.

4.	VALUATION AND COMPENSATION

On an ongoing basis, the Sub-Adviser shall monitor market developments for significant events occurring after the close of the primary markets for Fund assets that may materially affect their value, and shall promptly notify the Investment Adviser of any such event that comes to the Sub-Adviser’s attention. In addition, the Sub-Adviser will respond promptly to any request from the Investment Adviser or the Fund for information needed to assist the Fund in the valuation of any Fund asset, and to provide to the Investment Adviser or the Fund such information as is in the Sub-Adviser’s possession regarding the same. Sub-Adviser will promptly report all securities and other transactions for the Fund to the custodian, in a manner and at such times as agreed upon between Investment Adviser and Sub-Adviser.

Investment Adviser will pay Sub-Adviser as compensation for providing services in accordance with this Agreement those fees as set forth in Appendix A hereto. Investment Adviser and Sub-Adviser agree that all fees shall become due and owing to Sub-Adviser promptly after the termination date of Sub-Adviser with respect to the Fund and that the amount of such fees shall be calculated by treating the termination date as the next fee computation date. The annual base fee will be prorated for such fees owed through the termination date. In addition, Investment Adviser shall be responsible for extraordinary expenses incurred by Sub-Adviser in connection with the performance of its duties hereunder, including, without limitation, expenses incurred with respect to proxy voting execution, advice and reporting. The Sub-Adviser acknowledges and agrees that the Fund has no responsibility or liability for paying any fees to Sub-Adviser (or reimbursing Sub-Adviser for any costs or expenses) under this Agreement, and that all fees owed to Sub-Adviser hereunder shall be payable by the Investment Adviser.
