3. INTERPRETATION. Nothing herein contained shall be deemed to require the Trust or the Fund to take any action contrary to the Trust’s Trust Instrument or Bylaws, each as in effect from time to time, or any applicable statutory or regulatory requirement, including without limitation any requirements under the Investment Company Act of 1940 (the “1940 Act”), to which it is subject or by which it is bound, or to relieve or deprive the Trust’s Board of Trustees of its responsibility for or control of the conduct of the affairs of the Trust or the Fund.

4. DEFINITIONS. Any question of interpretation of any term or provision of this Agreement having a counterpart in or otherwise derived from the terms and provisions of the Management Contract or the 1940 Act, shall have the same meaning as and be resolved by reference to the Management Contract.
