 Responsibilities

Pursuant to Rule 30b1-4 promulgated under the Investment Company Act
of 1940, as amended (the “1940 Act”), the Fund is required to file Form N-PX no later than August 31 of each
year. On Form N-PX, the Fund is required to disclose, among other things, information concerning proxies relating to the Fund’s
portfolio investments, whether or not the Fund (or its Adviser) voted the proxies relating to securities held by the Fund and how it voted
on the matter and whether it voted for or against management.

_____________

The Eaton Vance Funds may be organized as trusts or corporations.
For ease of reference, the Funds may be referred to herein as Trusts and the Funds’ Board of Trustees or Board of Directors may
be referred to collectively herein as the Board.

To facilitate the filing of Form N-PX for the Fund:

| · | The Adviser is required to record, compile and transmit in a timely manner all data required to be filed on Form N-PX for the Fund       
 that it manages. Such data shall be transmitted to Eaton Vance Management, which acts as administrator to the Fund (the “Administrator”) 
 or the third-party service provider designated by the Administrator; and                                                                 |

| · | The Administrator is required to file Form N-PX on behalf of the Fund with the Securities and Exchange Commission (the “Commission”)  
 as required by the 1940 Act. The Administrator may delegate the filing to a third-party service provider provided each such filing is 
 reviewed and approved by the Administrator.                                                                                           |

IV. Conflicts of Interest

The Adviser, as a fiduciary to the Fund it manages, put the interests
of the Fund and its shareholders above those of the Adviser. When required to vote a proxy for the Fund, the Adviser and in some instances
Independent Trustees of the Funds, may have material business relationships with the issuer soliciting the proxy that could give rise
to a potential material conflict of interest for the Adviser. Pursuant to Rule 206(4)-7 under the Advisers Act, the Adviser Procedures
must include how the Adviser addresses material conflicts that may arise between the interest of the Adviser and the interests of the
Fund.

V. Reports and Review

The Administrator shall make copies of Form N-PX filed on behalf of
the Fund available for the Board’s review upon the Board’s request. The Administrator (with input from the Advis
