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 Fund, to invest in shares of other registered investment companies, such as the Acquired Fund, in excess of the limits of Section 12(d)(1) of the 1940 Act subject to compliance with the conditions of the Rule;

WHEREAS, the Acquiring Fund may, from time to time, invest in shares of the Acquired Fund in excess of the limitations of Section 12(d)(1)(A) in reliance on the Rule; and

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

1.	Terms of Investment

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

(i) Timing/advance notice of sales. The Acquiring Fund will use reasonable efforts to spread large sales of Acquired Fund shares (greater than 10% of the Acquired Fund’s total outstanding shares) over multiple days or to provide advance notification of anticipated sales to the Acquired Fund 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 sell Acquired Fund shares and constitutes an estimate that may differ materially from the amount, timing and manner in which a sales of Acquired Fund shares are effected, if any.

(ii) Scale of investment. Upon a reasonable request by the 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.

(iii) Redemption requests. 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, and the Tidal ETF Trust’s liquidity risk management procedures as applicable to the Acquired Fund, the Acquired Fund may honor redemption requests either partially or wholly in-kind.

(b) In order to assist the Acquiring Fund’s investment adviser with evaluating the complexity of the structure and fees and expenses associated with an investment by the Acquiring Fund in the Acquired Fund, and to assist the Acquiring Fund’s investment adviser with making the required findings under the Rule, the Acquired Fund shall, upon reasonable request from the Acquiring Fund, provide information on the fees and expenses and portfolio holdings of the Acquired Fund.

Representations of the Acquired Fund

In connection with any investment by the Acquiring Fund in the Acquired Fund in excess of the limitations in Section 12(d)(1)(A), the Acquired Fund agrees to: (i) comply with all conditions of the Rule, as interpreted or modified by the SEC or its Staff from time to time, applicable to the Acquired Fund; (ii) provide the Acquiring Fund on a timely basis with any updates to information previously provided under this Agreement that could materially impact the required findings made by the Acquiring Fund’s investment adviser under the Rule; (iii) comply with its obligations under this Agreement; and (iv) promptly notify the Acquiring Fund if the Acquired Fund fails to comply with the Rule with respect to an investment by the Acquiring Fund, as interpreted or modified by the SEC or its Staff from time to time, or this Agreement.
