The beneficial interest in each of the Funds shall be represented by a separate series of shares of beneficial interest, par value one cent ($.01) per share (the “Shares”), consisting of separate Classes. The Shares shall bear the name of the Fund to which it relates and shall represent the beneficial interest only in such Fund. An unlimited number of Shares of such series may be issued.

2. The Funds shall be authorized to invest in cash, securities, instruments and other property as from time to time described in the Trust’s then effective registration statement under the Securities Act of 1933 and the Investment Company Act of 1940, as amended (the “1940 Act”).

3. The Shares of each Class of each Fund shall have the additional relative rights and preferences, shall be subject to the liabilities, shall have the other characteristics, and shall be subject to other powers of the Trustees, all as set forth in paragraphs (a) through (m) of Section 4.2 of the Declaration. Without limitation of the foregoing sentence and as described in subsection (e) of Section 4.2 of the Declaration, each Share of such series shall be redeemable, shall be entitled to one vote, or a ratable fraction of one vote in respect of a fractional share, as to matters on which Shares of such series, or such Class as the case may be, shall be entitled to vote, and shall represent a share of the beneficial interest in the assets of the respective Fund, all as provided in the Declaration.

4. Liabilities, expenses, costs, charges or reserves that should be properly allocated to the Shares of a particular Class of a Fund may, pursuant to a Plan adopted by the Trustees pursuant to Rule 18f-3 under the 1940 Act, or such similar rule or provision or interpretation of the 1940 Act, be charged to and borne solely by such Class, and the bearing of expenses solely by a Class of Shares may be appropriately reflected and cause differences in net asset value attributable to, and the dividend, redemption and liquidation rights of, the Shares of different Classes.

5. Subject to the provisions and limitations of Section 7.3 of the Declaration and applicable law, this Certificate of Designation may be amended by an instrument in writing signed by a Majority of the Trustees (or by an officer of the Trust pursuant to the vote of a Majority of the Trustees), provided that, if any amendment materially adversely affects the rights of the Shareholders of the applicable Fund, or a particular Class of the respective Fund, such amendment may be adopted by an instrument in writing signed by a Majority of the Trustees (or by an officer of the Trust pursuant to the vote of a Majority of the Trustees) when authorized to do so by the vote in accordance with subsection (e) of Section 4.2 of the Declaration of the holders of a majority of all the Shares of the respective Fund, or the particular Class of the respective Fund, outstanding and entitled to vote.

6. All capitalized terms which are not defined herein shall have the same meanings as are assigned to those terms in the Declaration filed with the Secretary of State of The Commonwealth of Massachusetts.
