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

WHEREAS, the Fund desires to retain the Administrator to provide administrative services to the Fund in the manner and on the terms hereinafter set forth; and

WHEREAS, the Administrator is willing to provide administrative services to the Fund on the terms and conditions hereafter set forth.

NOW, THEREFORE, in consideration of the premises and the covenants hereinafter contained and for other good and valuable `consideration, the receipt and adequacy of which is hereby acknowledged, the Fund and the Administrator hereby agree as follows:

1. Duties of the Administrator.

(a) Employment of Administrator. The Fund hereby retains the Administrator to act as administrator of the Fund, and to furnish, or arrange for others to furnish, the administrative services, personnel and facilities described below, subject to review by and the overall control of the Board of Trustees of the Fund (the “Board”), for the period and on the terms and conditions set forth in this Agreement. The Administrator hereby accepts such retention and agrees during such period to render, or arrange for the rendering of, such services and to assume the obligations herein set forth subject to the reimbursement of costs and expenses provided for below. The Administrator shall for all purposes herein be deemed to be an independent contractor and shall, unless otherwise expressly provided or authorized herein, have no authority to act for or represent the Fund in any way or otherwise be deemed an agent of the Fund.

(b) Services. The Administrator shall perform (or oversee, or arrange for, the performance of) the administrative and compliance services necessary for the operation of the Fund, including, but not limited to, maintaining financial records, filing of the Fund’s tax returns, overseeing the calculation of the Fund’s net asset value, compliance monitoring (including diligence and oversight of the Fund’s other service providers), preparing reports to the Fund’s shareholders and reports filed with the Securities and Exchange Commission (the “SEC”) and other regulators, preparing materials and coordinating meetings of the Board, managing the payment of expenses, the payment and receipt of funds for investments and the performance of administrative and professional services rendered by others, providing office space, equipment and office services, and such other services as the Administrator, subject to review by the Board, shall from time to time determine to be necessary or useful to perform its obligations under this Agreement. The Administrator shall also, on behalf of the Fund, conduct relations with sub-administrators, custodians, depositories, depositaries, transfer agents, escrow agents, dividend disbursing agents, other shareholder servicing agents, accountants, attorneys, underwriters, brokers and dealers, corporate fiduciaries, insurers, banks and such other persons in any such other capacity deemed to be necessary or desirable in fulfilling its administrative duties. The Administrator shall make reports to the Board of its performance of its obligations hereunder and furnish advice and recommendations with respect to such other aspects of the business and affairs of the Fund as it shall determine to be desirable; provided that nothing herein shall be construed to require the Administrator to, and the Administrator shall not, in its capacity as Administrator pursuant to this

The Administrator further agrees that all records which it or its delegate maintains for the Fund pursuant to Rule 31a-1 under the Investment Company Act will be preserved for the periods prescribed by Rule 31a-2 under the Investment Company Act unless any such records are earlier surrendered as provided above. Records shall be surrendered in usable machine-readable form. The Administrator shall have the right to retain copies of such records subject to observance of its confidentiality obligations under this Agreement.

The foregoing shall not be applicable to any information that is publicly available when provided or thereafter becomes publicly available other than through a breach of this Agreement, or that is required to be disclosed by any regulatory authority, any authority or legal counsel of the parties hereto, by judicial or administrative process or otherwise by applicable law or regulation.

5. Limit of Liability. The Administrator 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 Administrator shall not be protected against any liability to the Fund or its shareholders to which the Administrator 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 Administrator’s services under this Agreement or otherwise as administrator 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 and monitored by the Administrator 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 Administrator had reasonable cause to believe its conduct was unlawful.

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.

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.

6. Activities of the Administrator. The services of the Administrator to the Fund are not to be deemed to be exclusive, and the Administrator and each affiliate is free to render services to others. It is understood that trustees, officers, employees and shareholders of the Fund are or may become interested in the Administrator and its affiliates, as trustees, officers, members, managers, employees, partners, shareholders or otherwise, and that the Administrator and trustees, officers, members, managers, employees, partners and shareholders of the Administrator and its affiliates are or may become similarly interested in the Fund as shareholders or otherwise.

7. Duration and Termination.

This Agreement may be terminated at any time, without the payment of any penalty, on 120 days’ written notice by the Fund, or upon 60 days’ written notice by the Administrator. The provisions of Section 5 of this Agreement shall remain in full force and effect, and the Administrator shall remain entitled to the benefits thereof, notwithstanding any termination of this Agreement. Further, notwithstanding the termination or expiration of this Agreement as aforesaid, the Administrator shall be entitled to any amounts owed under Section 4 through the date of termination or expiration, and Section 5 shall continue in force and effect and apply to the Administrator and its representatives as and to the extent applicable.

(c) This Agreement will automatically terminate in the event of its “assignment” (as such term is defined for purposes of Section 15(a)(4) of the Investment Company Act).
