The Trustees, by vote of a majority of the Trustees then in office, may elect from their number an Execu-tive Committee or other committees and may delegate thereto some or all of their powers except those which by law, by the Declaration of Trust, or by these By-Laws may not be dele-gated. Except as the Trustees may otherwise determine, any such committee may make rules for the conduct of its business, but unless otherwise provided by the Trustees or in such rules, its business shall be conducted so far as possible in the same manner as is provided by these By-Laws for the Trustees them-selves. All members of such committees shall hold such offices at the pleasure of the Trustees. The Trustees may abolish any such committee at any time. Any committee to which the Trust-ees delegate any of their powers or duties shall keep records of its meetings and shall report its action to the Trustees.

The Chairman of the Trustees, President, Treasurer or Secretary may determine which persons have authority to sign any documents on behalf of the Trust and establish related policies.

ARTICLE 9

Issuance of Share Certificates

9.1 Share Certificates. In lieu of issuing certificates for shares, the Trustees or the transfer 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.

The Trustees may at any time authorize the issuance of share certificates either in limited cases or to all sharehold-ers. In that event, a shareholder may receive a certificate stating the number of shares owned by him, in such form as shall be prescribed from time to time by the Trustees. Such certificate shall be signed by the president or a vice presi-dent and by the treasurer or assistant treasurer. Such signa-tures may be facsimiles 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 certifi-cate is issued, it may be issued by the Trust with the same effect as if he were such officer at the time of its issue.

9.2 Loss of Certificates. In case of the alleged loss or destruction or the mutilation of a share certificate, a dupli-cate certificate may be issued in place thereof, upon such terms as the Trustees shall prescribe.

9.3 Issuance of New Certificate to Pledgee. The Trustees may in their discretion, or the Treasurer may pursuant to authority delegated by the Trustees, institute a policy of enabling a pledgee of shares transferred as collateral security to obtain a new certificate if the instrument of transfer substantially describes the debt or duty that is intended to be secured thereby. Such new certificate shall express on its face that it is held as collateral security, and the name of the pledgor shall be stated thereon, who alone shall be liable as a shareholder, and entitled to vote thereon.

9.4 Discontinuance 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.

ARTICLE 10

Dealings with Trustees and Officers

10.1 General. Any Trustee, officer or other agent of the Trust may acquire, own and dispose of shares of the Trust to the same extent as if he were not a Trustee, officer or agent; and the Trustees may accept subscriptions to shares or repurchase shares from any firm or company in which any Trustee, officer or other agent of the Trust may have an interest.
