Re: Fee Waiver/Expense Reimbursement

Ladies and Gentlemen:

American Beacon Advisors, Inc. (“AmBeacon”) notifies you that, for the funds listed in Attachment A to this letter (the “Funds”), it will waive its management fee and/or reimburse expenses of the Fund, to the extent necessary so that expenses of the Fund, exclusive of taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, expenses associated with securities sold short, litigation, and other extraordinary expenses, do not exceed the annual rates listed on Attachment A.

During the period until the expiration date of each expense limitation in Attachment A, the related expense limitation arrangements for each of the Funds may only be modified by mutual agreement of the parties that, with respect to the Trust, includes a majority vote of the “non-interested” Trustees of the Trust. For a period of up to three years following AmBeacon’s contractual fee waiver or reimbursement, AmBeacon may be reimbursed by a Fund if reimbursement does not cause the expenses of the Fund exclusive of taxes, interest, brokerage commissions, acquired fund fees and expenses, securities lending fees, expenses associated with securities sold short, litigation, and other extraordinary expenses, to exceed the lesser of the contractual percentage limit in effect at the time of the waiver/reimbursement or the time of the recoupment.

We understand and intend that you will rely on this undertaking in preparing and filing the Registration Statements on Form N-1A for the Fund with the Securities and Exchange Commission, in accruing each Fund’s expenses for purposes of calculating its net asset value per share and for other purposes permitted under Form N-1A and/or the Investment Company Act of 1940, as amended, and expressly permit you to do so.

Respectfully,
American Beacon Advisors, Inc.
