Exhibit (k)(6)

RULE 12d1-4

EXCHANGE TRADED FUND OF CLOSED-END FUNDS INVESTMENT AGREEMENT

This Agreement, dated as of January 19, 2022 , between First Trust CEF Income Opportunity ETF (the “Acquiring Fund”) and each closed-end investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”) advised by Blackstone Liquid Credit Strategies LLC (the “Adviser”), that is listed on Appendix A hereto (as may be amended from time to time), severally and not jointly (each an “Acquired Fund”).

WHEREAS, the Acquiring Fund is a series of First Trust Exchange-Traded fund VIII (the “Trust”) that is registered with the U.S. Securities and Exchange Commission (“SEC”) as an open-end management investment company under the 1940 Act and the Acquiring Fund operates as an exchange-traded fund;

WHEREAS, each Acquired Fund is registered with the SEC as a closed-end management investment company and the parties hereto intend that this Agreement 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)(1)(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)(1)(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)(1)(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, 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; and

WHEREAS, the 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)(1) 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 Fund and the Acquired Funds agree that the Acquiring Fund 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, each Acquired Fund and the Acquiring Fund agree as follows:

(i) the 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;

(ii) the Acquiring Fund shall not purchase or otherwise acquire securities issued by an Acquired Fund in excess of the limits in Section 12(d)(1)(A)(i) of the 1940 Act (i.e., the 3% Limit); and

(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) the 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 the 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 thirty (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.

(c) In order to assist the Acquiring Fund’s investment advisor 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 Acquiring Fund with information on the fees and expenses of the Acquired Fund reasonably requested by the 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, the 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.

2. Representations of the Acquired Funds.

In connection with any investment by the Acquiring Fund in an 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 Acquired Funds; (ii) comply with its obligations under this Agreement; and (iii) promptly notify the Acquiring Fund if such 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.

3. Representations of the Acquiring Fund.

In connection with any investment by the Acquiring Fund in an Acquired Fund in excess of the limitations in Section 12(d)(1)(A), the Acquiring 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 Acquiring Fund; (ii) comply with its obligations under this Agreement; and (iii) promptly notify the Acquired Fund if the Acquiring Fund fails to comply with the Rule with respect to its investment in such Acquired Fund, as interpreted or modified by the SEC or its staff from time to time, or this Agreement.

Likewise, the Acquired Funds shall not use the name, or any Service Xxxx, of the Acquiring Funds, or any of their affiliates, in marketing materials unless the Acquired Funds first receive prior written approval of the Acquiring Funds. Notwithstanding the foregoing, each Acquiring Fund and Acquired Fund consents to the use of its name and the names of its affiliates to the extent such use is required by applicable law, rule, or regulation, including, without limitation, use in disclosure documents, shareholder communications, advertising, sales literature, and similar communications of an Acquired Fund or Acquiring Fund, as the case may be, to the extent required by applicable law, rule, or regulation.
