The contractual arrangement may only be changed or eliminated by the Board of Trustees upon 60 days’ written notice to the Adviser. The Adviser may recoup from the Fund any waived amount or reimbursed expenses pursuant to this agreement if such recoupment does not cause the Fund’s Total Annual Fund Operating Expenses after such recoupment to exceed the lesser of (i) the Expense Limit in effect at the time of the waiver or reimbursement and (ii) the Expense Limit in effect at the time of recoupment and the recoupment is made within three years after the end of the month in which the Adviser incurred the expense. Fee Waiver/Expense Reimbursement and Total Annual Fund Operating Expenses After Fee Waiver/Expense Reimbursement have been restated to reflect the current expense limitation arrangement.
