WHEREAS, the Acquiring Fund Trust and the Acquired Fund Trust are registered with the U.S. Securities and Exchange Commission ("SEC") as investment companies under the Investment Company Act of 1940, as amended, (the "1940 Act");

WHEREAS, Section 12(d)(1)(A) of the 1940 Act limits the extent to which a registered investment company may invest in shares of other registered investment companies, Section 12(d)(1)(B) limits the extent to which a registered investment company, its principal underwriter or registered brokers or dealers may knowingly sell shares of such registered investment company to other investment companies, and Section 12(d)(1)(C) limits the extent to which an investment company may invest in the shares of a registered closed-end investment company;

WHEREAS, Rule 12d1-4 under the 1940 Act (the "Rule") permits registered investment companies, such as the Acquiring Funds, to invest in shares of other registered investment companies, such as the Acquired Funds, in excess of the limits of Section 12(d)(1) of the 1940 Act subject to compliance with the conditions of the Rule; and

WHEREAS, an Acquiring Fund may, from time to time, invest in shares of one or more Acquired Funds in excess of the limitations of Section 12(d)(1)(A) in reliance on the Rule.

NOW THEREFORE, in accordance with the Rule, the Acquiring Funds and the Acquired Funds desire to set forth the following terms pursuant to which the Acquiring Funds may invest in the Acquired Funds in reliance on the Rule.

I. TERMS OF INVESTMENT

1.1 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, each Acquiring Fund and each Acquired Fund agree as follows:

(i)In-kind redemptions. The Acquiring Fund acknowledges and agrees that, if and to the extent consistent with the Acquired Fund’s registration statement, as amended from time to time, the Acquired Fund may honor any redemption request partially or wholly in-kind.

(ii)Timing/advance notice of redemptions. The Acquiring Fund will use reasonable efforts to spread large redemption requests over multiple days or to provide advance notification of redemption requests to the Acquired Fund(s) whenever practicable and consistent with the Acquiring Fund’s best interests. The Acquired Fund

acknowledges and agrees that any notification provided pursuant to the foregoing is not a commitment to redeem and constitutes an estimate that may differ materially from the amount, timing and manner in which a redemption request is submitted, if any.

(iii)Scale of investment. Upon 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 investment in the Acquired Fund. The Acquired Fund acknowledges and agrees that any information provided pursuant to the foregoing is not a commitment to purchase and constitutes an estimate that may differ materially from the amount, timing and manner in which a purchase order is submitted, if any.

1.2       Section 1.1 shall not apply to any purchases or sales of Acquired Funds via secondary market transactions.

1.3      In order to assist the Acquiring Fund’s investment adviser (the "Adviser") with evaluating the complexity of the structure and fees and expenses associated with an investment in an Acquired Fund, each Acquired Fund shall provide each Acquiring Fund and its Adviser with information reasonably requested to comply with the terms and conditions of the Rule, including information on the fees and expenses of the Acquired Fund.

II. REPRESENTATIONS OF THE ACQUIRING AND ACQUIRED FUNDS
