In addition to the information expressly required to be in the Shareholder Notice, the Shareholder shall also provide such other information as the Trustees may reasonably request in order to assess whether the matter is a proper matter for Shareholders’ consideration and determine a position with respect to such proposal.

Section 3. Record Date for Meetings. For the purpose of determining the Shareholders who are entitled to notice of and to vote at any meeting, or to participate in any distribution, or for the purpose of any other action, the Trustees may from time to time close the transfer books for such period, not exceeding thirty (30) days, as the Trustees may determine; or without closing the transfer books the Trustees may fix a date not more than sixty (60) days prior to the date of any meeting of Shareholders or distribution or other action as a record date for the determination of the persons to be treated as Shareholders of record for such purposes.

Section 4. Proxies. At any meeting of Shareholders, any holder of Shares entitled to vote thereat may vote by proxy, provided that no proxy shall be voted at any meeting unless it shall have been placed on file with the Secretary, or with such other officer or agent of the Trust as the Secretary may direct, for verification prior to the time at which such vote shall be taken. Pursuant to a resolution of a majority of the Trustees, proxies may be solicited in the name of one or more Trustees or one or more of the officers of the Trust. Only Shareholders of record shall be entitled to vote. Each full Share shall be entitled to one vote and fractional Shares shall be entitled to a vote of such fraction. When any Share is held jointly by several persons, any one of them may vote at any meeting in person or by proxy in respect to such Share, but if more than one of them shall be present at such meeting in person or by proxy, and such joint owners or their proxies so present disagree as to any vote to be cast, such vote shall not be received in respect of such Share. A proxy purporting to be executed by or on behalf of a Shareholder shall be deemed valid unless challenged at or prior to its exercise, and the burden of proving invalidity shall rest on the challenger. If the holder of any such Share is a minor or a person of unsound mind, and subject to guardianship or to the legal control of any other person as regards the charge or management of such Share, he may vote by his guardian or such other person appointed or having such control, and such vote may be given in person or by proxy.

Such consent shall be treated for all purposes as a vote taken at a meeting of Shareholders.

(a) The Trustees shall cause to be delivered to the Custodian all securities owned by the Trust or to which it may become entitled, and shall order the same to be delivered by the Custodian only upon completion of a sale, exchange, transfer, pledge, loan of portfolio securities to another person or other disposition thereof, and upon receipt by the Custodian of the consideration therefor or a certificate of deposit or a receipt of an issuer or of its Transfer Agent, all as the Trustees may generally or from time to time require or approve, or to a successor Custodian; and the Trustees shall cause all funds owned by the Trust or to which it may become entitled to be paid to the Custodian, and shall order the same disbursed only for investment against delivery of the securities acquired, or the return of cash held as collateral for loans of portfolio securities, or in payment of expenses, including management compensation, and liabilities of the Trust, including distributions to Shareholders, or to a successor Custodian; provided, however, that nothing herein shall prevent delivery of securities for examination to the broker selling the same in accord with the “street delivery” custom whereby such securities are delivered to such broker in exchange for a delivery receipt exchanged on the same day for an uncertified check of such broker to be presented on the same day for certification. Notwithstanding anything to the contrary in these By-laws, upon receipt of proper instructions, which may be standing instructions, the Custodian may delivery funds in the following cases. In connection with repurchase agreements, the Custodian may transmit, prior to receipt on behalf of the Fund of any securities or other property, funds from the Fund’s custodian account to a special custodian approved by the Trustees of the Fund, which funds shall be used to pay for securities to be purchased by the Fund subject to the Fund’s obligation to sell and the seller’s obligation to repurchase such securities. In such case, the securities shall be held in the custody of the special custodian. In connection with the Trust’s purchase or sale of financial futures contracts, the Custodian shall transmit, prior to receipt on behalf of the Fund of any securities or other property, funds from the Trust’s custodian account in order to furnish to any maintain funds with brokers as margin to guarantee the performance of the Trust’s futures obligations in accordance with the applicable requirements of commodities exchanges and brokers.

(b) In case of the resignation, removal or inability to serve of any such Custodian, the Trust shall promptly appoint another bank or trust company meeting the requirements of this Article X as successor Custodian. The agreement with the Custodian shall provide that the retiring Custodian shall, upon receipt of notice of such appointment, deliver the funds and property of the Trust in its possession to and only to such successor, and that pending appointment of a successor Custodian, or a vote of the Shareholders to function without a Custodian, the Custodian shall not deliver funds and property of the Trust to the Trust, but may delivery them to a bank or trust company of its own selection, having an aggregate capital, surplus and undivided profits (as shown in its last published report) of at least five million dollars ($5,000,000), as the property of the Trust to be held under terms similar to those on which they were held by the retiring Custodian.

ARTICLE XI

Sale of Shares of the Trust

The Trustees may from time to time issue and sell or cause to be issued and sold Shares for cash or other property, which shall in every case be paid or delivered to the Custodian as agent of the Trust before the delivery of any certificate for such shares. The Shares, including additional Shares which may have been purchased by the Trust (herein sometimes referred to as “treasury shares”), may not be sold at less than the net asset value thereof determined by or on behalf of the Trustees as of a time within forty-eight (48) hours, excluding Sundays and holidays, next preceding the time of such determination, except (1) in connection with an offering to the holders of Shares; (2) with the consent of a majority of the holders of Shares; (3) upon conversion of a convertible security in accordance with its terms; (4) upon the exercise of any warrant issued in accordance with the provisions of Section 18(d) of the 1940 Act; or (5) under such other circumstances as the Commission may permit by rules and regulations or orders for the protection of investors.

No Shares need be offered to existing Shareholders before being offered to others. No Shares shall be sold by the Trust (although Shares previously contracted to be sold may be issued upon payment therefor) during any period when the determination of net asset value is suspended by declaration of the Trustees. In connection with the acquisition by merger or otherwise of all or substantially all the assets of an investment company (whether a regulated or private investment company or a personal holding company), the Trustees may issue or cause to be issued Shares and accept in payment therefor such assets at not more than market value in lieu of cash, notwithstanding that the federal income tax basis to the Trust of any assets so acquired may be less than the market value, provided that such assets are of the character in which the Trustees are permitted to invest the funds of the Trust.

ARTICLE XII

Dividends and Distributions

Section 1. Distributions to Shareholders. The Trustees shall from time to time distribute ratably among the Shareholders such proportion of the net profits, surplus (including paid-in surplus), capital, or assets held by the Trustees as they may deem proper. Such distributions may be made in cash or property (including without limitation any type of obligations of the Trust or any assets thereof), and the Trustees may distribute ratably among the Shareholders additional Shares issuable hereunder in such manner, at such times, and on such terms as the Trustees may deem proper. Such distributions may be among the Shareholders of record at the time of declaring a distribution or among the Shareholders of record at such other date or time or dates or times as the Trustees shall determine. The Trustees may always retain from the net profits such amount as they may deem necessary to pay the debts or expenses of the Trust or to meet obligations of the Trust, or as they may deem desirable to use in the conduct of its affairs or to retain for future requirements or extensions of the business. The decision of the Trustees as to what, in accordance with generally accepted accounting principles, is net profits, surplus, capital or assets shall be final, and except as specifically provided herein the decision of the Trustees as to what expenses and charges of the Trust shall be charged against assets and what against income shall be final, all subject to any applicable provisions of the 1940 Act and rules, regulations and orders of the Commission promulgated thereunder.

Inasmuch as the computation of net income and gains for federal income tax purposes may vary from the computation thereof on the books, the above provisions shall be interpreted to give to the Trustees the power in their discretion to distribute for any fiscal year as ordinary dividends and as capital gains distributions, respectively, additional amounts sufficient to enable the Trust to avoid or reduce liability for taxes.

11

Section 2. Dividend Reinvestment Plans. The Trustees may adopt and offer to Shareholders such dividend reinvestment plans, cash dividend payout plans or related plans as the Trustees shall deem appropriate.

Section 3. Stock Dividends. Anything in these By-laws to the contrarynotwithstanding, the Trustees may at any time declare and distribute pro rata among the Shareholders a “stock dividend” out of either authorized but unissued Shares or treasury shares of the Trust or both.

ARTICLE XIII

Amendments

These By-laws, or any of them, may be altered, amended or repealed, or new By-laws may be adopted (a) by Majority Shareholder Vote, or (b) by the Trustees, provided, however, that no By-law may be amended, adopted or repealed by the Trustees if such amendment, adoption or repeal requires, pursuant to law, the Declaration or these By-laws, a vote of the Shareholders or if such amendment, adoption or repeal changes or affects the provisions of Sections 1 and 4 of Article X or the provisions of this Article XIII.

ARTICLE XIV

Miscellaneous

The Trust shall not impose any restrictions upon the transfer of the Shares of the Trust except as provided in the Declaration, but this requirement shall not prevent the charging of customary transfer agent fees.

The Trust shall not permit any officer or Trustee of the Trust, or any partner, officer or director of the Investment Adviser or underwriters of the Trust to deal for or on behalf of the Trust with himself as principal or agent, or with any partnership, association or corporation in which he has a financial interest; provided that the foregoing provisions shall not prevent (a) officers and Trustees of the Trust or partners, officers or directors of the Investment Adviser or underwriter of the Trust from buying, holding or selling shares in the Trust, or from being partners, officers or directors or otherwise financially interested in the Investment Adviser or underwriter of the Trust; (b) purchases or sales of securities or other property by the Trust from or to an affiliated person or to the Investment Adviser or underwriters of the Trust if such transaction is exempt from the applicable provisions of the 1940 Act; (c) purchases of investments for the portfolio of the Trust or sales of investments owned by the Trust through a security dealer who is, or one or more of whose partners, shareholders, officers or directors is, an officer or Trustee of the Trust, or a partner, officer or director of the Investment Adviser or underwriter of the Trust, if such transactions are handled in the capacity of broker only and commissions charged do not exceed customary brokerage charges for such services; (d) employment of legal counsel, registrar, Transfer Agent, dividend disbursing agent or Custodian who is, or has a partner, shareholder, officer, or director who is, an officer or Trustee of the Trust, or a partner, officer of director of the Investment Adviser or underwriter of the Trust, if only customary fees are charged for services to the Trust; (e) sharing statistical research, legal and management expenses and office hire and expenses with any other investment company in which an officer or Trustee of the Trust, or a partner, officer or director of the Investment Adviser or underwriter of the Trust, is an officer or director or otherwise financially interested.
