EXPENSE LIMITATION AGREEMENT

EXPENSE LIMITATION AGREEMENT

          This EXPENSE LIMITATION AGREEMENT (the “Agreement”) is made as of the 23rd day of January, 2012 by and between SUNAMERICA SERIES TRUST, a Massachusetts business trust (the “Trust”), on behalf of the SUNAMERICA DYNAMIC ALLOCATION PORTFOLIO (the “Portfolio”), and SUNAMERICA ASSET MANAGEMENT CORP., a Delaware corporation (the “Adviser”).

          WHEREAS, the Adviser serves as the investment adviser to the Portfolio pursuant to an Investment Advisory and Management Agreement (the “Advisory Agreement”); and

          WHEREAS, the Trust, on behalf of the Portfolio, and the Adviser desire to enter into an agreement whereby the Adviser agrees to waive its fees and/or reimburse expenses to the extent necessary to cap the annual fund operating expenses of the Portfolio at a certain level.

          NOW THEREFORE, it is hereby agreed between the parties hereto as follows:

	1.		The Adviser agrees to waive its fees and/or reimburse expenses to the extent necessary so that the “annual fund operating expenses,” as described in the registration statement form applicable to the Trust for the Portfolio’s Class 3 shares do not exceed 0.55% of the average daily net assets of the Portfolio. Annual fund operating expenses shall not include extraordinary expenses, as determined under generally accepted accounting principals, or “acquired fund fees and expenses.”
	2.		This Agreement shall be effective as of the date first written above and shall continue in effect with respect to the Portfolio until April 30, 2013 (the “Expiration Date”) unless earlier terminated by the Board of Trustees of the Trust, 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 Investment Company Act of 1940, as amended. This Agreement shall continue in effect for successive one-year periods from the Expiration Date only if the Adviser notifies the Portfolio prior to the Expiration Date that it agrees to extend the current expense cap applicable to the Portfolio for an additional one-year period. Upon the termination of the Advisory Agreement, this Agreement shall automatically terminate.
	3.		The Adviser hereby retains the right to receive reimbursements of, and the Trust, on behalf of the Portfolio, hereby agrees to reimburse reductions of the fees paid to the Adviser under the Advisory Agreement and the expenses paid by the Adviser or reimbursed by it in accordance with paragraph 1 above, for a period of two years after the occurrence of any

			waiver and/or reimbursement; provided, however, that such payment to the Adviser shall not be made if it would cause the annual fund operating expenses of the Portfolio’s Class 3 shares to exceed 0.55%. Upon the termination of this Agreement, the Adviser will continue to be entitled to receive reimbursements of amounts already waived and/or reimbursed under Section 1, provided that such amounts are paid to the Adviser in accordance with the provisions of Section 1, and at the expense cap levels in effect at the time such waivers and/or reimbursements occurred.
	4.		This Agreement shall be constructed in accordance with the laws of the State of New York without giving effect to principles of conflicts of law.
	5.		This Agreement may be amended by mutual consent or the parties hereto in writing.

          IN WITNESS WHEREOF, the parties hereto have caused this Expense Limitation Agreement to be executed by their duly authorized officers as of the day and year first above written.
