Issuance of Share Certificates

9.1 Sale of Shares.  Except as otherwise determined by the Trustees, the Trust will issue and sell for cash or securities from time to time, full and fractional shares of its shares of beneficial interest, such shares to be issued and sold at a price of not less than net asset value per share, as from time to time determined in accordance with the Declaration of Trust and these By-Laws and, in the case of fractional shares, at a proportionate reduction in such price.  In the case of shares sold for securities, such securities shall be valued in accordance with the provisions for determining value of assets of the Trust as stated in the Declaration of Trust and these By-Laws.  The officers of the Trust are severally authorized to take all such actions as may be necessary or desirable to carry out this Section 9.1.

9.2 Share Certificates.  In lieu of issuing certificates for shares, the Trustees or the transfer agent either may 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, for all purposes hereunder, be deemed 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.

The Trustees at any time may authorize the issuance of share certificates.  In that event, each shareholder shall be entitled to a certificate stating the number of shares owned by him or her, in such form as shall be prescribed from time to time by the Trustees.  Such certificate shall be signed by the President or Vice President and by the Treasurer or Assistant Treasurer.  Such signatures may be facsimile if the certificate is signed by a transfer 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 cease 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.

ARTICLE 10
Indemnification

10.1 Trustees, Officers, etc.  The Trust shall indemnify each of its Trustees and officers (including persons who serve at the Trust's request as directors, officers or trustees of another organization in which the Trust has any interest as a shareholder, creditor or otherwise) (hereinafter referred to as a "Covered Person") against all liabilities and expenses, including but not limited to amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and counsel fees reasonably incurred by any Covered Person in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, before any court or administrative or legislative body, in which such Covered Person may be or may have been involved as a party or otherwise or with which such person may be or may have been threatened, while in office or thereafter, by reason of being or having been such a Trustee or officer, except with respect to any matter as to which such Covered Person shall have been finally adjudicated in a decision on the merits in any such action, suit or other proceeding not to have acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust and except that no Covered Person shall be indemnified against any liability to the Trust or its Shareholders to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office.  Expenses, including counsel fees so incurred by any such Covered Person (but excluding amounts paid in satisfaction of judgments, in compromise or as fines or penalties), may be paid from time to time by the Trust in advance of the final disposition or any such action, suit or proceeding upon receipt of an undertaking by or on behalf of such Covered Person to repay amounts so paid to the Trust if it is ultimately determined that indemnification of such expenses is not authorized under this Article, provided that (a) such Covered Person shall provide security for his or her undertaking, (b) the Trust shall be insured against losses arising by reason of such Covered Person's failure to fulfill his or her undertaking, or (c) a majority of the Trustees who are disinterested persons and who are not "interested persons" (as that term is defined in the Investment Company Act of 1940, as amended) (provided that a majority of such Trustees then in office act on the matter), or independent legal counsel in a written opinion, shall determine, based on a review of readily available facts (but not a full trial-type inquiry), that there is reason to believe such Covered Person ultimately will be entitled to indemnification.

10.2 Compromise Payment.  As to any matter disposed of (whether by a compromise payment, pursuant to a consent decree or otherwise) without an adjudication in a decision on the merits by a court, or by any other body before which the proceeding was brought, that such Covered Person either (a) did not act in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust or (b) is liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office, indemnification shall be provided if (a) approved as in the best interest of the Trust, after notice that it involves such indemnification, by at least a majority of the Trustees who are disinterested persons and are not Interested Persons (provided that a majority of such Trustees then in office act on the matter), upon a determination, based upon a review of readily available facts (but not a full trial-type inquiry) that such Covered Person acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust and is not liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office, or (b) there has been obtained an opinion in writing of independent legal counsel, based upon a review of readily available facts (but not a full trial-type inquiry) to the effect that such Covered Person appears to have acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust and that such indemnification would not protect such Covered Person against any liability to the Trust to which such Covered Person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties

-5-

NY 73286856v5

involved in the conduct of his office.  Any approval pursuant to this Section shall not prevent the recovery from any Covered Person of any amount paid to such Covered Person in accordance with this Section as indemnification if such Covered Person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that such Covered Person's action was in the best interests of the Trust or to have been liable to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Covered Person's office.

10.3 Indemnification Not Exclusive.  The right of indemnification hereby provided shall not be exclusive of or affect any other rights to which any such Covered Person may be entitled.  As used in this Article 10, the term "Covered Person" shall include such person's heirs, executors and administrators, and a "disinterested person" is a person against whom none of the actions, suits or other proceedings in question or another action, suit, or other proceeding on the same or similar grounds is then or has been pending.  Nothing contained in this Article shall affect any rights to indemnification to which personnel of the Trust, other than Trustees and officers, and other persons may be entitled by contract or otherwise under law, nor the power of the Trust to purchase and maintain liability insurance on behalf of such person.

10.4 Limitation.  Notwithstanding any provisions in the Declaration of Trust and these By-Laws pertaining to indemnification, all such provisions are limited by the following undertaking set forth in the rules promulgated by the Securities and Exchange Commission:

In the event that a claim for indemnification is asserted by a Trustee, officer or controlling person of the Trust in connection with the registered securities of the Trust, the Trust will not make such indemnification unless (i) the Trust has submitted, before a court or other body, the question of whether the person to be indemnified was liable by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of duties, and has obtained a final decision on the merits that such person was not liable by reason of such conduct or (ii) in the absence of such decision, the Trust shall have obtained a reasonable determination, based upon a review of the facts, that such person was not liable by virtue of such conduct, by (a) the vote of a majority of Trustees who are neither interested persons as such term is defined in the Investment Company Act of 1940, nor parties to the proceeding or (b) an independent legal counsel in a written opinion.

The Trust will not advance attorneys' fees or other expenses incurred by the person to be indemnified unless (i) the Trust shall have received an undertaking by or on behalf of such person to repay the advance unless it is ultimately determined that such person is entitled to indemnification and (ii) one of the following conditions shall have occurred:  (x) such person shall provide security for his undertaking, (y) the Trust shall be insured against losses arising by reason of any lawful advances or (z) a majority of the disinterested, non-party Trustees of the Trust, or an independent legal counsel in a written opinion, shall have determined that based on a review of readily available facts there is reason to believe that such person ultimately will be found entitled to indemnification.

ARTICLE 11
Shareholders

11.1 Meetings.  A meeting of the shareholders of the Trust or of any series or class shall be called by the Secretary whenever ordered by the Trustees, or requested in writing by the holder or holders of at least 30% of the outstanding shares entitled to vote at such meeting.  If the meeting is a meeting of the shareholders of one or more series or class of shares, but not a meeting of all shareholders of the Trust, then only the shareholders of such one or more series or classes shall be entitled to notice of and to vote at the meeting.  If the Secretary, when so ordered or requested, refuses or neglects for more than five days to call such 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.

11.2 Access to Shareholder List.  Shareholders of record may apply to the Trustees for assistance in communicating with other shareholders for the purpose of calling a meeting in order to vote upon the question of removal of a Trustee.  When ten or more shareholders of record who have been such for at least six months preceding the date of application and who hold in the aggregate shares having a net asset value of at least $25,000 or at least 1% of the outstanding shares, whichever is less, so apply, the Trustees shall within five business days either:

(i) afford to such applicants access to a list of names and addresses of all shareholders as recorded on the books of the Trust; or

(ii) inform such applicants of the approximate number of shareholders of record and the approximate cost of mailing material to them and, within a reasonable time thereafter, mail materials submitted by the applicants to all such shareholders of record.  The Trustees shall not be obligated to mail materials which they believe to be misleading or in violation of applicable law.

11.3 Record Dates.  For the purpose of determining the shareholders of any series or class who are entitled to vote or act at any meeting or any adjournment thereof, or who are entitled to receive payment of any dividend or of any other distribution, the Trustees from time to time may fix a time, which shall be not more than 90 days before the date of any meeting of shareholders or the date of payment of any dividend or of any other distribution, as the record date for determining the shareholders of such series or class having the right to notice of and to vote at such meeting and any adjournment thereof or the right to receive such dividend or distribution, and in such case only shareholders of record on such record date shall have such right notwithstanding any transfer of shares on the books of the Trust after the record date; or without fixing such record date the Trustees may for any such purposes close the register or transfer books for all or part of such period.

11.4 Place of Meetings.  All meetings of the shareholders shall be held at the principal office of the Trust or at such other place within the United States as shall be designated by the Trustees or the President of the Trust.

11.5 Notice of Meetings.  A written notice of each meeting of shareholders, stating the place, date and hour and the purposes of the meeting, shall be given at least ten days before the meeting to

-7-

NY 73286856v5

each shareholder entitled to vote thereat at his or her address as it appears in the records of the Trust or the address (including for these purposes email address or facsimile number, as applicable) supplied by the shareholder for the purpose of notice.  Such notice shall be given by the Secretary or an Assistant Secretary or by an officer designated by the Trustees.  No notice of any meeting of shareholders need be given to a shareholder if a written waiver of notice, executed before or after the meeting by such shareholder or his attorney thereunto duly authorized, is filed with the records of the meeting.

11.6 Communications with Shareholders.  Any notices, reports, statements or other communications with shareholders of any kind required under the Declaration of Trust, these By-Laws or applicable law may be sent, delivered or made available in any reasonable manner as may be determined by the Trustees if not otherwise prohibited by applicable law, including, without limitation, by email or other electronic means or by posting on a website; and such communications may be sent, delivered or otherwise made available to shareholders in accordance with householding or other similar rules under which a single copy of such notice or report may be sent to shareholders who reside at the same address.  No communication need by given to any shareholder who shall have failed to inform the Trust of the shareholder's current address and the Trustees may from time to time adopt, or may authorize the officers or agents of the Trust to adopt, procedures or policies with respect to communications to shareholders that are returned to the Trust or its agents as undeliverable and similar matters.

11.7 Ballots.  No ballot shall be required for any election unless requested by a shareholder present or represented at the meeting and entitled to vote in the election.

11.8 Proxies.  Shareholders entitled to vote may vote either in person or by proxy in writing dated not more than six months before the meeting named therein, which proxies shall be filed with the Secretary or other person responsible to record the proceedings of the meeting before being voted.  Unless otherwise specifically limited by their terms, such proxies shall entitle the holders thereof to vote at any adjournment of such meeting but shall not be valid after the final adjournment of such meeting.  The placing of a shareholder's name on a proxy pursuant to telephonic or electronically transmitted instructions obtained pursuant to procedures reasonably designed to verify that such instructions have been authorized by such shareholder shall constitute execution of such proxy by or on behalf of such shareholder.
