(b) Each Class may pay a different share of other expenses, not including advisory or custodial fees or other expenses related to the management of the Trust’s assets, if these expenses are actually incurred in a different amount by that Class, or if the Class receives services of a different kind or to a different degree than other Classes (“Class Expenses”);

4. Nothing herein contained shall be deemed to require the Trust to take any action contrary to its Declaration of Trust or By-Laws or any applicable statutory or regulatory requirement to which it is subject or by which it is bound, or to relieve or deprive the Board of Trustees of the responsibility for and control of the conduct of the affairs of the Trust.

5. This Plan shall become effective as to each Fund upon approval with respect to such Fund by a vote of the Board of Trustees and vote of a majority of the Trustees who are not “interested persons” of the Trust (the “Independent Trustees”).

6. This Plan shall continue in effect indefinitely unless terminated by a vote of the Board of Trustees of the Trust.
