Eaton Vance shall for all purposes herein be deemed to be an independent contractor and shall, except as otherwise expressly provided or authorized, have no authority to act for or represent the Fund in any way or otherwise be deemed an agent of the Fund.

Eaton Vance shall provide the Fund with such investment management and supervision as the Fund may from time to time consider necessary for the proper supervision of the Fund. As investment adviser to the Fund, Eaton Vance shall furnish continuously an investment program and shall determine

from time to time what securities and other investments shall be acquired, disposed of or exchanged and what portion of the Fund’s assets shall be held uninvested, subject always to the applicable restrictions of the Memorandum and Articles of Association of the Fund and the Prospectus. Eaton Vance is authorized, in its discretion and without prior consultation with the Fund to buy, sell, and otherwise trade in any and all types of securities, derivatives, commodities and investment instruments on behalf of the Fund.

Eaton Vance shall take, on behalf of the Fund, all actions which it deems necessary or desirable to implement the investment policies of the Fund.

Eaton Vance shall place all orders for the purchase or sale of portfolio securities for the account of the Fund either directly with the issuer or with brokers or dealers selected by Eaton Vance, and to that end Eaton Vance is authorized as the agent of the Fund to give instructions to the custodian of the Fund as to deliveries of securities and payments of cash for the account of the Fund. In connection with the selection of such brokers or dealers and the placing of such orders, Eaton Vance shall adhere to procedures adopted by the Directors of the Fund and the Trustees of the Parent Company. Eaton Vance is authorized on behalf of the Fund to enter into agreements and execute any documents required to make investments.
