WHEREAS, the Fund is a closed-end management investment company that has elected to be treated as a business development company (“BDC”) under the Investment Company Act of 1940 (the “Investment Company Act”);

WHEREAS, the Adviser is an investment adviser that has registered under the Investment Advisers Act of 1940 (the “Advisers Act”); and

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the parties hereby agree as follows:

1. Duties of the Adviser.

(a) The Fund hereby employs the Adviser to act as the investment adviser to the Fund and to manage the investment and reinvestment of the assets of the Fund and to ensure that the Fund meets the qualifications necessary to maintain its status as BDC under the Investment Company Act, subject to the supervision of the Fund’s board of trustees (the “Board of Trustees”), for the period and upon the terms herein set forth, (i) in accordance with the investment objective, policies and restrictions that are set forth in the Fund’s Registration Statement on Form 10, as the same shall be amended from time to time (as amended, the “Registration Statement”), (ii) in accordance with the Investment Company Act and (iii) during the term of this Agreement, in accordance with all other applicable federal and state laws, rules and regulations, and the Fund’s charter and by-laws. Without limiting the generality of the foregoing, the Adviser hereby undertakes and agrees, upon the terms and conditions herein set forth, to provide overall investment advisory services for the Fund and in connection therewith to, in accordance with the Fund’s investment objective, policies and restrictions as in effect from time to time:

(c) The Adviser hereby accepts such employment and agrees during the term hereof to render the services described herein for the compensation provided herein.

The Adviser, and not the Fund, shall be responsible for any compensation payable to any sub-adviser. Any sub-advisory agreement entered into by the Adviser shall be in accordance with the requirements of the Investment Company Act and other applicable federal and state law. The Fund acknowledges that the Adviser makes no warranty that any investments made by the Adviser hereunder will not depreciate in value or at any time not be affected by adverse tax consequences, nor does it give any warranty as to the performance or profitability of the assets or the success of any investment strategy recommended or used by the Adviser.

(e) The Adviser shall for all purposes herein provided be deemed to be an independent contractor and, except as expressly provided or authorized herein, shall have no authority to act for or represent the Fund in any way or otherwise be deemed an agent of the Fund.

(f) The Adviser shall keep and preserve for the period required by the Investment Company Act any books and records relevant to the provision of its investment advisory services to the Fund and shall specifically maintain all books and records with respect to the Fund’s portfolio transactions and shall render to the Fund’s Board of Trustees such periodic and special reports as the Board may reasonably request.

3. Transactions with Affiliates. The Adviser is authorized on behalf of the Fund, from time to time when deemed to be in the best interests of the Fund and to the extent permitted by applicable law, to purchase and/or sell securities in which the Adviser or any of its affiliates underwrites, deals in and/or makes a market and/or may perform or seek to perform investment banking services for issuers of such securities. The Adviser is further authorized, to the extent permitted by applicable law, to select brokers (including any brokers affiliated with the Adviser) for the execution of trades for the Fund.

4. Best Execution; Research Services.

(a) The Adviser is authorized, for the purchase and sale of the Fund’s portfolio securities, to employ such dealers and brokers as may, in the judgment of the Adviser, implement the policy of the Fund to obtain the best results, taking into account such factors as price, including dealer spread, the size, type and difficulty of the transaction involved, the firm’s general execution and operational facilities and the firm’s risk in positioning the securities involved. Consistent with this policy, the Adviser is authorized to direct the execution of the Fund’s portfolio transactions to dealers and brokers furnishing statistical information or research deemed by the Adviser to be useful or valuable to the performance of its investment advisory functions for the Fund. It is understood that in these circumstances, as contemplated by Section 28(e) of the Securities Exchange Act of 1934, as amended, the commissions paid may be higher than those which the Fund might otherwise have paid to another broker if those services had not been provided. Information so received will be in addition to and not in lieu of the services required to be performed by the Adviser. It is understood that the expenses of the Adviser will not necessarily be reduced as a result of the receipt of such information or research. Research services furnished to the Adviser by brokers who effect securities transactions for the Fund may be used by the Adviser in servicing other investment companies, entities or funds and accounts which it manages. Similarly, research services furnished to the Adviser by brokers who effect securities transactions for other investment companies, entities or funds and accounts which the Adviser manages may be used by the Adviser in servicing the Fund. It is understood that not all of these research services are used by the Adviser in managing any particular account, including the Fund.

The Adviser and its affiliates may aggregate purchase or sale orders for the assets with purchase or sale orders for the same security for other clients’ accounts of the Adviser or of its affiliates, the Adviser’s own accounts and hold proprietary positions in accordance with its current aggregation and allocation policy (collectively, the “Advisory Clients”), but only if (x) in the Adviser’s reasonable judgment such aggregation results in an overall economic or other benefit to the assets taking into consideration the advantageous selling or purchase price, brokerage commission and other expenses and factors and (y) the Adviser’s actions with respect to aggregating orders for multiple Advisory Clients, as well as the Fund, are consistent with applicable law. However, the Adviser is under no obligation to aggregate any such orders under any circumstances.

10

(b) Excess Brokerage Commissions. The Adviser is hereby authorized, to the fullest extent now or hereafter permitted by law, to cause the Fund to pay a member of a national securities exchange, broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission another member of such exchange, broker or dealer would have charged for effecting that transaction, if the Adviser determines in good faith, taking into account such factors as price (including the applicable brokerage commission or dealer spread), size of order, difficulty of execution, and operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities, that such amount of commission is reasonable in relation to the value of the brokerage and/or research services provided by such member, broker or dealer, viewed in terms of either that particular transaction or its overall responsibilities with respect to the Fund’s portfolio, and constitutes the best net results for the Fund.

5. Compensation of the Adviser. The Fund agrees to pay, and the Adviser agrees to accept, as compensation for the services provided by the Adviser hereunder, a base management fee (“Base Management Fee”) and an incentive fee (“Incentive Fee”) as hereinafter set forth. The Fund shall make any payments due hereunder to the Adviser or to the Adviser’s designee as the Adviser may otherwise direct.

(a) Base Management Fee. The Base Management Fee is accrued monthly and paid quarterly in arrears at an annual rate of 1.00% of the value of Fund’s net assets as of the beginning of the first business day of the applicable month. For the first calendar quarter in which the Fund has operations, net assets will be measured as the average of net assets (i) at the date the Fund first delivers a drawdown notice to its investors and (ii) at the end of such first calendar quarter. For the purposes of this Agreement, net assets means the Fund’s total assets less liabilities determined on a consolidated basis in accordance with U.S. GAAP.

(b) Incentive Fee. The Incentive Fee will consist of two components that are independent of each other, with the result that one component may be payable even if the other is not. A portion of the Incentive Fee is based on a percentage of the Fund’s income and a portion is based on a percentage of the Fund’s capital gains, each as described below.

(i) Incentive Fee on Pre-Incentive Fee Net Investment Income. The portion based on the Fund’s income is based on Pre-Incentive Fee Net Investment Income Returns. “Pre-Incentive Fee Net Investment Income Returns” means, as the context requires, either the dollar value of, or percentage rate of return on the value of the Fund’s net assets at the end of the immediate preceding quarter from, interest income, dividend income and any other income (including any other fees, such as commitment, origination, structuring, diligence and consulting fees or other fees that the Fund receives from portfolio companies) accrued during the calendar quarter, minus the Fund’s operating expenses accrued for the quarter (including the Base Management Fee, expenses payable under the Administration Agreement, and any interest expense or fees on any credit facilities or outstanding debt and dividends paid on any issued and outstanding preferred shares, but excluding the incentive fee and any distribution or shareholder servicing fees).

Pre-Incentive Fee Net Investment Income Returns include, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with pay-in-kind interest and zero coupon securities), accrued income that the Fund has not yet received in cash. Pre-Incentive Fee Net Investment Income Returns do not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. The impact of expense support payments and recoupments are also excluded from Pre-Incentive Fee Net Investment Income Returns.

11

Pre-Incentive Fee Net Investment Income Returns, expressed as a rate of return on the value of the Fund’s net assets at the end of the immediately preceding quarter, is compared to a “hurdle rate” of return of 1.500% per quarter (6.000% annualized).

The Fund will pay the Adviser an incentive fee quarterly in arrears with respect to the Fund’s Pre-Incentive Fee Net Investment Income Returns in each calendar quarter as follows:

These calculations are prorated for any period of less than three months and adjusted for any share issuances or repurchases during the relevant quarter.

(ii) Incentive Fee Based on Capital Gains. The second component of the Incentive Fee, the Capital Gains Incentive Fee, is payable at the end of each calendar year in arrears.

The amount payable equals:

Each year, the fee paid for the capital gains incentive fee is net of the aggregate amount of any previously paid capital gains incentive fee for all prior periods. The Fund will accrue, but will not pay, a capital gains incentive fee with respect to unrealized appreciation because a capital gains incentive fee would be owed to the Adviser if the Fund were to sell the relevant investment and realize a capital gain. In no event will the capital gains incentive fee payable pursuant to this Agreement be in excess of the amount permitted by the Advisers Act, including Section 205 thereof.

12

The fees that are payable under this Agreement for any partial period will be appropriately prorated.

(c) The Adviser (i) waives its right to receive the Base Management Fee and the Incentive Fee for the first 12-month period following the date of this Agreement and (ii) will waive 50% of each of the Base Management Fee and the Incentive Fee for the subsequent 12-month period. The fee waiver will terminate 24 months following the date of this Agreement.

6. Representations and Warranties.

(a) The Adviser represents and warrants that it is duly registered and authorized as an investment adviser under the Advisers Act, and the Adviser agrees to maintain effective all material requisite registrations, authorizations and licenses, as the case may be, until the termination of this Agreement.

7. Limitations on the Employment of the Adviser. The services of the Adviser to the Fund are not exclusive, and the Adviser may engage in any other business or render similar or different services to others including, without limitation, the direct or indirect sponsorship or management of other investment based accounts or commingled pools of capital, however structured, having investment objectives similar to those of the Fund, so long as its services to the Fund hereunder are not impaired thereby, and nothing in this Agreement shall limit or restrict the right of any manager, partner, officer or employee of the Adviser to engage in any other business or to devote his or her time and attention in part to any other business, whether of a similar or dissimilar nature, or to receive any fees or compensation in connection therewith (including fees for serving as a director of, or providing consulting services to, one or more of the Fund’s portfolio companies, subject to applicable law). So long as this Agreement or any extension, renewal or amendment remains in effect, the Adviser shall be the only investment adviser for the Fund, subject to the Adviser’s right to enter into sub-advisory agreements. It is understood that the Adviser shall not have any obligation to recommend for purchase or sale any loans which its principals, affiliates or employees may purchase or sell for its or their own accounts or for any other client or account if, in the opinion of the Adviser, such transaction or investment appears unsuitable, impractical or undesirable for the Fund. Nothing herein shall be construed as constituting the Adviser an agent of the Fund. The Adviser assumes no responsibility under this Agreement other than to render the services called for hereunder. It is understood that directors, officers, employees and shareholders of the Fund are or may become interested in the Adviser and its affiliates, as directors, officers, employees, partners, shareholders, members, managers or otherwise, and that the Adviser and directors, officers, employees, partners, shareholders, members and managers of the Adviser and its affiliates are or may become similarly interested in the Fund as shareholders or otherwise.

The Adviser and its affiliates may face conflicts of interest as described in the Fund’s Registration Statement and/or the Fund’s periodic filings with the SEC (as such disclosures may be updated from time to time) and such disclosures have been provided, and any updates will be provided, to the Board of Trustees in connection with its consideration of this Agreement and any future renewal of this Agreement.

13

8. Responsibility of Dual Directors, Officers and/or Employees. If any person who is a manager, partner, officer or employee of the Adviser or the Administrator is or becomes a director, officer and/or employee of the Fund and acts as such in any business of the Fund, then such manager, partner, officer and/or employee of the Adviser or the Administrator shall be deemed to be acting in such capacity solely for the Fund, and not as a manager, partner, officer or employee of the Adviser or the Administrator or under the control or direction of the Adviser or the Administrator, even if paid by the Adviser or the Administrator.

9. Limitation of Liability of the Adviser; Indemnification.

(a) The Adviser and its officers, managers, partners, agents, employees, controlling persons, members and any other person or entity affiliated with it (the “Indemnified Parties”) shall not be liable for any error of judgment or mistake of law or for any act or omission or any loss suffered by the Fund in connection with the matters to which this Agreement relates, provided that the Adviser shall not be protected against any liability to the Fund or its shareholders to which the Adviser would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence on its part in the performance of its duties or by reason of the reckless disregard of its duties and obligations (“disabling conduct”). An Indemnified Party may consult with counsel and accountants in respect of the Fund’s affairs and shall be fully protected and justified in any action or inaction which is taken in accordance with the advice or opinion of such counsel and accountants; provided, that such counsel or accountants were selected with reasonable care. Absent disabling conduct, the Fund will indemnify the Indemnified Parties against, and hold them harmless from, any damages, liabilities, costs and expenses (including reasonable attorneys’ fees and amounts reasonably paid in settlement) arising from the rendering of the Adviser’s services under this Agreement or otherwise as adviser for the Fund. The Indemnified Parties shall not be liable under this Agreement or otherwise for any loss due to the mistake, action, inaction, negligence, dishonesty, fraud or bad faith of any broker or other agent; provided, that such broker or other agent shall have been selected, engaged or retained by the Adviser in good faith, unless such action or inaction was made by reason of disabling conduct, or in the case of a criminal action or proceeding, where the Adviser had reasonable cause to believe its conduct was unlawful.

(b) Indemnification shall be made only following: (i) a final decision on the merits by a court or other body before which the proceeding was brought that the Indemnified Party was not liable by reason of disabling conduct or (ii) in the absence of such a decision, a reasonable determination, based upon a review of the facts, that the Indemnified Party was not liable by reason of disabling conduct by (a) the vote of a majority of a quorum of trustees of the Fund who are neither “interested persons” of the Fund nor parties to the proceeding (“disinterested non-party trustees”) or (b) an independent legal counsel in a written opinion.

(c) An Indemnified Party shall be entitled to advances from the Fund for payment of the reasonable expenses (including reasonable counsel fees and expenses) incurred by it in connection with the matter as to which it is seeking indemnification in the manner and to the fullest extent permissible under law. Prior to any such advance, the Indemnified Party shall provide to the Fund a written affirmation of its good faith belief that the standard of conduct necessary for indemnification by the Fund has been met and a written undertaking to repay any such advance if it should ultimately be determined that the standard of conduct has not been met. In addition, at least one of the following additional conditions shall be met: (a) the Indemnified Party shall provide a security in form and amount acceptable to the Fund for its undertaking; (b) the Fund is insured against losses arising by reason of the advance; or (c) a majority of a quorum of disinterested non-party trustees or independent legal counsel, in a written opinion, shall have determined, based on a review of facts readily available to the Fund at the time the advance is proposed to be made, that there is reason to believe that the Indemnified Party will ultimately be found to be entitled to indemnification.
