WHEREAS, the Trust intends that this Agreement be applicable to its existing series as of the date hereof and all series subsequently established by the Trust;

WHEREAS, each Acquired Fund is registered with the SEC as a closed-end management investment company and advised by the Adviser and the parties hereto intend that this Agreement to be applicable to all registered closed-end funds advised by the Adviser that are listed on Appendix A, as may be amended from time to time;

WHEREAS, Section 12(d)(l)(A) limits the extent to which a registered investment company may invest in shares of other registered investment companies, including, in pertinent part, Section 12(d)(l)(A)(i) which prohibits a registered investment company (and any company or companies controlled by it) to purchase or otherwise acquire any security issued by any other investment company if the acquiring company (and any company or companies controlled by it) immediately after such purchase or acquisition own in the aggregate more than 3% of the total outstanding voting stock of the acquired company (the “3% Limit”). Section 12(d)(l)(C) of the 1940 Act further limits the extent to which an investment company may invest in the shares of a registered closed-end investment company;

WHEREAS, an Acquiring Fund may, from time to time, invest in shares of one or more Acquired Funds in excess of certain limitations of Section 12(d)(l) in reliance on the Rule.

NOW THEREFORE, in consideration of the premises and the mutual covenants and conditions contained herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1. Terms of Investment.

(a) In accordance with the Rule, the Acquiring Funds and the Acquired Funds agree that the Acquiring Funds may invest in the Acquired Funds in reliance on the Rule and as provided herein.

(b) In order to help reasonably address the risk of undue influence on an Acquired Fund by an Acquiring Fund, and to assist the Acquired Fund’s investment adviser with making the required findings under the Rule if necessary, each Acquired Fund and each Acquiring Fund agree as follows:

(i) an Acquiring Fund and its advisory group as such term is defined in the Rule, will not control (individually or in the aggregate) an Acquired Fund. Upon a reasonable request by an Acquired Fund, the Acquiring Fund will provide summary information regarding the anticipated timeline of its investment in the Acquired Fund and the scale of its contemplated investments in the Acquired Fund, to the extent it does not include material non-public information;

(ii) no Acquiring Fund shall purchase or otherwise acquire securities issued by an Acquired Fund in excess of the limits in Section 12(d)(l)(A)(i) of the 1940 Act (i.e., the 3% Limit) without prior written notice to the Acquired Fund;

(iii) (A) except as provided in (B) below, or otherwise required by the Acquiring Fund’s organizational documents or applicable law or rules thereunder, the Acquiring Fund will vote its securities held of an Acquired Fund in the same proportion as the vote of all other holders of such securities (“echo voting”);

(B) An Acquiring Fund will consider voting on a non-routine matter in its own discretion (rather than echo voting) if requested by the Acquired Fund. If an Acquired Fund requests that an Acquiring Fund consider a non-routine matter that is pending shareholder vote, the Acquired Fund must provide notice of the non-routine shareholder vote to the parties listed in Section 4 of this Agreement at least 30 days prior to the vote. Upon a timely request, the Acquiring Fund will consider the non-routine matter and vote in accordance with the best interest of its unitholders or shareholders; and

(iv) the Acquiring Fund shall not make any purchase or acquisition of shares in an Acquired Fund that results in the Acquiring Fund and its Advisory Group (as defined in the Rule), individually or in the aggregate, holding more than 5% of the outstanding securities of an Acquired Fund without prior written consent from the Acquired Fund, which consent may be withheld, delayed, denied, or conditioned in the Acquired Fund’s sole and absolute discretion.

(c) In order to assist the Acquiring Fund’s principal underwriter or depositor with evaluating the complexity of the structure and the fees and expenses associated with an investment in an Acquired Fund, each Acquired Fund shall provide the respective Acquiring Fund with information on the fees and expenses of the Acquired Fund reasonably requested by such Acquiring Fund with reference to the Rule. In accordance with the foregoing and in recognition of each Acquired Fund’s obligations regarding disclosure of material nonpublic information under applicable laws, rules and regulations, including without limitation Regulation FD, each Acquiring Fund and Acquired Fund agree that the information on fees and expenses of each Acquired Fund shall be provided through delivery or access to publicly available documents.
