Fund Name	Period Covered
Loomis Sayles High Income Fund	November 30, 2016 – January 31, 2018

During the period covered by this agreement, the expense reimbursement arrangement set forth above for the Fund may only be modified by a majority vote of the “non-interested” Trustees of the Trust affected.
