Article IV
SHAREHOLDERS’ MEETINGS

Section 4.1Special Meetings. A special meeting of the Shareholders shall be called by the Secretary whenever (i) ordered by the President of the Trust, (ii) ordered by the Trustees; or (iii) requested in writing by the Shareholders holding at least ten percent of the outstanding shares entitled to vote (provided that such Shareholders prepay the costs to the Trust of preparing and mailing the notice of the meeting). Whenever ten or more Shareholders meeting the qualifications set forth in Section 16(c) of the 1940 Act, as the same may be amended from time to time, seek the opportunity of furnishing materials to the other Shareholders with a view to obtaining signatures on such a request for a meeting, the Trustees shall comply with the provisions of said Section 16(c) with respect to providing such Shareholders access to the list of the Shareholders of record of the Trust or the mailing of such materials to such Shareholders of record, subject to any rights provided to the Trust or any Trustees provided by said Section 16(c). If the Secretary, when so ordered or requested, refuses or neglects for more than 30 days to call such special meeting, the Trustees or the Shareholders so requesting, may, in the name of the Secretary, call the meeting by giving notice thereof in the manner required when notice is given by the Secretary. If the meeting is a meeting of the Shareholders of one or more Series or Classes, but not a meeting of all Shareholders of the Trust, then only special meetings of the Shareholders of such one or more Series or Classes shall be called and only the shareholders of such one or more Series or Classes shall be entitled to notice of and to vote at such meeting.

Section 4.2Notices. Except as above provided, notices of any meeting of the Shareholders shall be given by the Secretary by delivering or mailing, postage prepaid, to each Shareholder entitled to vote at said meeting, written or printed notification of such meeting at least 15 days before the meeting, to such address as may be registered with the Trust by the Shareholder. Notice of any Shareholder meeting need not be given to any Shareholder if a written waiver of notice, executed before or after such meeting, is filed with the record of such meeting, or to any Shareholder who shall attend such meeting in person or by proxy. Notice of adjournment of a Shareholders’ meeting to another time or place need not be given, if such time and place are announced at the meeting or reasonable notice is given to persons present at the meeting and the adjourned meeting is held within a reasonable time after the date set for the original meeting.

Section 4.3Voting; Proxies. Subject to the provisions of the Trust Agreement, Shareholders entitled to vote may vote either in person or by proxy, provided that either (i) an instrument authorizing such proxy to act is executed by the Shareholder in writing and dated not more than 11 months before the meeting, unless the instrument specifically provides for a longer period; or (ii) the Shareholder authorizes an electronic, telephonic, computerized or other alternative to execution of a written instrument authorizing the proxy to act, which authorization is received not more than 11 months before the meeting. Proxies shall be delivered to the Secretary of the Trust or other person responsible for recording the proceedings before being voted. A proxy with respect to Shares held in the name of two or more persons shall be valid if executed or authorized by one of them, unless at or prior to exercise of such proxy the Trust receives a specific written notice to the contrary from any one of them. Unless otherwise specifically limited by their terms, proxies shall entitle the holder thereof to vote at any adjournment of a meeting. A proxy purporting to be exercised by or on behalf of a Shareholder

-4-

shall be deemed valid unless challenged at or prior to its exercise and the burden or proving invalidity shall rest on the challenger. At all meetings of the Shareholders, unless the voting is conducted by inspectors, all questions relating to the qualifications of voters, the validity of proxies, and the acceptance or rejection of votes shall be decided by the Chairman of the meeting. Except as otherwise provided herein or in the Trust Agreement, as these Bylaws or such Trust Agreement may be amended or supplemented from time to time, all matters relating to the giving, voting or validity of proxies shall be governed by the General Corporation Law of the State of Delaware relating to proxies, and judicial interpretations thereunder, as if the Trust were a Delaware corporation and the Shareholders were shareholders of a Delaware corporation.

Section 4.4Place Of Meeting. All special meetings of the Shareholders shall be held at the principal place of business of the Trust or at such other place in the United States as the Trustees may designate.

Section 4.5Action Without a Meeting. Any action to be taken by Shareholders may be taken without a meeting, except where a larger vote is required by law or by the Trust Agreement, if a majority of the Shareholders entitled to vote on the matter consent to the action in writing and the written consents are filed with the records of meetings of Shareholders of the Trust. Such consent shall be treated for all purposes as a vote at a meeting of the Trustees held at the principal place of business of the Trust.

Section 4.6Quorum and Required Vote. One-third of Shares entitled to vote in person or by proxy shall be a quorum for the transaction of business at a meeting of Shareholders, except that where any provision of law or of the Trust Agreement permits or requires that Shareholders of any Series shall vote as a Series (or the Shareholders of a Class shall vote as a Class), then one-third of the aggregate number of Shares of that Series (or that Class) entitled to vote shall be necessary to constitute a quorum for the transaction of business by that Series (or that Class). Any lesser number shall be sufficient for adjournment. Any adjourned session or sessions may be held within a reasonable time after the date set for the original meeting, without the necessity of further notice. Except when a larger vote is required by law or by the Trust Agreement, a majority of the Shares voted in person or by proxy shall decide any questions and a plurality shall elect a Trustee, provided that where any provision of law or of the Trust Agreement permits or requires that holders of any Series shall vote as a Series (or that the holders of any Class shall vote as a Class), then a majority of the Shares present in person or by proxy of that Series (or Class) voted on the matter in person or by proxy shall decide that matter insofar as that Series (or Class) is concerned.

SHARES OF BENEFICIAL INTEREST

Section 6.1Beneficial Interest. The beneficial interest in the Trust shall at all times be divided into such transferable Shares of one or more separate and distinct Series, or Classes thereof, as the Trustees shall from time to time create and establish. The number of Shares is unlimited, and each Share of each Series or class thereof shall be without par value and shall represent an equal proportionate interest with each other Share in the Series, none having priority or preference over another, except to the extent that such priorities or preferences are established with respect to one or more Classes of Shares consistent with applicable law and any rule or order of the Commission.

Section 6.2Transfer of Shares. The Shares of the Trust shall be transferable, so as to affect the rights of the Trust, only by transfer recorded on the books of the Trust, in person or by attorney.

Section 6.3Equitable Interest Not Recognized.

Section 6.4Share Certificate. No certificates certifying the ownership of Shares shall be issued except as the Trustees may otherwise authorize. The Trustees may issue certificates to a Shareholder of any Series or Class for any purpose and the issuance of a certificate to one or more Shareholders shall not require the issuance of certificates generally. In the event that the Trustees authorize the issuance of Share certificates, such certificate shall be in the form proscribed from time to time by the Trustees and shall be signed by the President or a Vice President and by the Treasurer, Assistant Treasurer, Secretary or Assistant Secretary. Such signatures may be facsimiles if the certificate is signed by a transfer or shareholder services agent or by a registrar, other than a Trustee, officer or employee of the Trust. In case any officer who has signed or whose facsimile signature has been placed on such certificate shall have ceased to be such officer before such certificate is issued, it may be issued by the Trust with the same effect as if he or she were such officer at the time of its issue.

-6-

In lieu of issuing certificates for Shares, the Trustees or the transfer or shareholder services agent may either issue receipts therefor or may keep accounts upon the books of the Trust for the record holders of such Shares, who shall in either case be deemed, for all purposes hereunder, to be the holders of certificates for such Shares as if they had accepted such certificates and shall be held to have expressly assented and agreed to the terms hereof.

Section 6.5Loss of Certificate. In the case of the alleged loss or destruction or the mutilation of a Share certificate, a duplicate certificate may be issued in place thereof, upon such terms as the Trustees may prescribe.

Section 6.6Discontinuance of Issuance Of Certificates. The Trustees may at any time discontinue the issuance of Share certificates and may, by written notice to each Shareholder, require the surrender of Share certificates to the Trust for cancellation. Such surrender and cancellation shall not affect the ownership of Shares in the Trust.

Section 6.7Establishment of Record Dates. The Trustees may close the Share transfer books of the Trust for a period not exceeding 150 days preceding the date of any meeting of Shareholders, or the date for the payment of any dividend or other distribution, or the date for the allotment of rights, or the date when any change or conversion or exchange of Shares shall go into effect; or in lieu of closing the stock transfer books as aforesaid, the Trustees may fix in advance a date, not exceeding 150 days preceding the date of any meeting of Shareholders, or the date for payment of any dividend or other distribution, or the date for the allotment of rights, or the date when any change or conversion or exchange of Shares shall go into effect, as a record date for the determination of the Shareholders entitled to notice of, and to vote at, any such meeting, or entitled to receive payment of any such dividend or other distribution, or to any such allotment of rights, or to exercise the rights in respect of any such change, conversion or exchange of Shares, and in such case such Shareholders and only such Shareholders as shall be Shareholders of record on the date so fixed shall be entitled to such notice of, and to vote at, such meeting or to receive payment of such dividend or other distribution, or to receive such allotment or rights, or to exercise such rights, as the case may be, notwithstanding any transfer of any Shares on the books of the Trust after any such record date fixed as aforesaid.

Article VII

The Trust may not acquire or obtain a contract for insurance that protects or purports to protect any Trustee or officer of the Trust against any liability to the Trust or its Shareholders to which he or she would otherwise be subject by reason or willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office.
