The Administrator is hereby authorized, but not required, to enter into one or more sub-administration agreements as the Administrator determines necessary in order to carry out the services set forth in this paragraph, subject to the prior approval of the Company, with other administrators (each, a “Sub-Administrator”) pursuant to which the Administrator may obtain the services of the Sub-Administrator(s) to assist the Administrator in fulfilling its responsibilities hereunder. To the extent the Administrator outsources any of its functions, at the request of the Administrator, the Company will pay the fees associated with such functions on a direct basis without profit to the Administrator.

The Administrator agrees to maintain and keep all books, accounts and other records of the Company that relate to activities performed by the Administrator hereunder and, if required by the Investment Company Act, will maintain and keep such books, accounts and records in accordance with that Act. In compliance with the requirements of Rule 31a-3 under the Investment Company Act, the Administrator agrees that all records which it maintains for the Company shall at all times remain the property of the Company, shall be readily accessible during normal business hours, and shall be promptly surrendered upon the termination of this Agreement or otherwise on written request. The Administrator further agrees that all records which it maintains for the Company 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 parties hereto agree that each shall treat confidentially all information provided by each party to the other regarding its business and operations. All confidential information provided by a party hereto, including nonpublic personal information pursuant to Regulation S-P of the SEC, shall be used by any other party hereto solely for the purpose of rendering services pursuant to this Agreement and, except as may be required in carrying out this Agreement, shall not be disclosed to any third party, without the prior consent of such providing party. 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.

Prior to any such advance, the Indemnified Party shall provide to the Company a written affirmation of its good faith belief that the standard of conduct necessary for indemnification by the Company 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 Company for its undertaking; (b) the Company 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 Company 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.

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 Company as shareholders or otherwise.

This Agreement shall become effective as of the date hereof, and shall remain in force with respect to the Company for two years thereafter, and thereafter continue from year to year, but only so long as such continuance is specifically approved at least annually by (i) the Board and (ii) a majority of those trustees of the Board who are not parties to this Agreement or “interested persons” (as defined in the Investment Company Act) of any such party to this Agreement.

This Agreement may be terminated at any time, without the payment of any penalty, by vote of the trustees of the Company, or by the Administrator, upon 60 days’ written notice to the other party. This Agreement may not be assigned by a party without the prior consent of the other party.

This Agreement may be amended pursuant to a written instrument by mutual consent of the parties.

This Agreement shall be construed in accordance with laws of the State of New York and the applicable provisions of the Investment Company Act, if any. To the extent that the applicable laws of the State of New York, or any of the provisions herein, conflict with the applicable provisions of the Investment Company Act, if any, the latter shall control.

This Agreement contains the entire agreement of the parties and supersedes all prior agreements, understandings and arrangements with respect to the subject matter hereof
