WITNESSETH THAT:

WHEREAS, VIA, the Adviser and the Subadviser are each investment advisers registered with the U.S. Securities and Exchange Commission (the “SEC”) under the Investment Advisers Act of 1940 (the “Advisers Act”);

WHEREAS, the Adviser and the Trust are parties to an Investment Advisory Agreement dated as of June 12, 20217, as amended (the “Advisory Agreement”), with respect to the Fund pursuant to which the Adviser may enter into subadvisory agreements with registered investment advisers to act as subadvisers to the Fund;

WHEREAS, pursuant to the Advisory Agreement, the Adviser and the Trust have entered into a subadvisory agreement with the Subadviser dated as of August 27, 2019, on behalf of the Fund (the “Subadvisory Agreement”), pursuant to which the Subadviser serves as subadviser to the Fund, and which Subadvisory Agreement provides in substance for its automatic termination in the event of its assignment, in accordance with the requirements of Section 15(a)(4) of the Investment Company Act of 1940, as amended (the “1940 Act”);

WHEREAS, VIA and the Adviser are both indirect wholly owned subsidiaries of Virtus Investment Partners, Inc. (“Virtus”) and are, therefore, under common control of Virtus;

WHEREAS, certain registered investment advisers within the corporate organizational structure of Virtus will be reorganized and VIA will replace the Adviser as adviser to the Fund (the “Reorganization”);

WHEREAS, following the Reorganization, VIA and the Adviser will remain indirect wholly owned subsidiaries of Virtus, and therefore under the control of Virtus;

WHEREAS, the Reorganization will not result in a change of actual control or management of either the Adviser or VIA and, therefore, under Rule 2a-6 of the 1940 Act, is not an assignment that would cause a termination of the Subadvisory Agreement in accordance with its terms; and

WHEREAS, at a meeting held on November 20, 2024, the Board of Trustees of the Trust (the “Board”), including a majority of Trustees who are not “interested persons” (as defined in Section 2(a)(19) of the 1940 Act) of the Trust or any investment adviser to the Trust, approved the appointment of VIA as the investment adviser to the Fund in connection with the Reorganization and authorized any officer of the Fund to execute and deliver such documentation appropriate to accomplish the transfer and assumption of the Subadvisory Agreement;

WHEREAS, each of the Trust and the Subadviser wishes to confirm its express written consent to the transfer, assumption and amendment of the Subadvisory Agreement as set forth in this Agreement;
