MASTER ADVISORY FEE WAIVER AGREEMENT

This MASTER ADVISORY FEE WAIVER AGREEMENT (“Agreement”) is dated as of the 29^th day of April, 2024, by and between SUNAMERICA SERIES TRUST (the “Trust”), on behalf of each of its series from time to time set forth in Schedule A attached hereto (each, a “Portfolio” and collectively, the “Portfolios”), severally and not jointly, and SUNAMERICA ASSET MANAGEMENT, LLC, a Delaware limited liability company (the “Adviser”).

WITNESSETH:

WHEREAS, the Trust is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end, management investment company, and is organized as a Massachusetts business trust, and each Portfolio is a series of the Trust; and

WHEREAS, the Adviser and the Trust are parties to that certain Investment Advisory and Management Agreement, dated January 1, 1999 (as amended, restated or otherwise modified from time to time, the “Advisory Agreement”), pursuant to which the Adviser serves as the investment adviser to each Portfolio; and

WHEREAS, the Trust, on behalf of each Portfolio, pays the Adviser as compensation for services provided to the Portfolios, an advisory fee at the annual rate set forth in the Advisory Agreement (the “Advisory Fee”); and

WHEREAS, the Adviser has agreed to waive a portion of its Advisory Fee under the Advisory Agreement with respect to each Portfolio (the “Fee Waiver”). The Trust, on behalf of each Portfolio, and the Adviser, therefore, wish to enter into this Agreement to effect the Fee Waiver for each Portfolio on the terms and conditions set forth in this Agreement; and

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

1. Fee Waiver. During the Term (as defined in Section 2 below), the Adviser shall waive a portion of its Advisory Fee under the Advisory Agreement with respect to each Portfolio so that the Advisory Fee payable by the Portfolio is equal to the rate set forth in Schedule A attached hereto.

2. Term; Termination. The term of the Fee Waiver with respect to a Portfolio shall begin on the effective date hereof of this Agreement (or on the date on which a Portfolio is added to Schedule A, if later, pursuant to Section 4) and shall continue in effect until the close of business on the date set forth on Schedule A (or such other date as agreed to in writing between the Adviser and the Trust) (“Term”) unless the Fee Waiver is earlier terminated with respect to such Portfolio by the Board of Trustees of the Trust (the “Board”), including a majority of the independent trustees. Independent trustees are trustees who are not deemed to be “interested persons” of the Trust, as defined under Section 2(a)(19) of the 1940 Act. The Term of the Fee Waiver with respect to a Portfolio may be continued from year to year thereafter provided each such continuance is agreed to by the Adviser and the

Trust. Upon termination of the Advisory Agreement with respect to a Portfolio, this Agreement shall automatically terminate with respect to such Portfolio.

3. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without giving effect to principles of conflicts of law.

4. Amendments. This Agreement may be amended by mutual consent of the parties hereto in writing. Schedule A to this Agreement may be amended from time to time to reflect the termination and/or modification of any Fee Waiver with respect to a Portfolio or class thereof or the addition of a series of the Trust. With respect to any series that is added to Schedule A hereto after the date of this Agreement, this Agreement shall become effective with respect to such series on the date Schedule A is amended to reflect the addition of the series under this Agreement, subject to obtaining the requisite approval from the Board.

5. Headings. The headings in this Agreement are included for convenience of reference only and in no other way define or delineate any of the provisions hereof or otherwise affect their construction or effect.

6. Entire Agreement. This Agreement constitutes the whole agreement between the parties and supersedes any previous fee waiver agreement relating to the Portfolios covered by this Agreement.
