the President, if there be no Chairman of the Board, shall be the chief
executive officer of the corporation and shall preside at all meetings of the
stockholders and directors at which such officer is present.

during the intervals between the meetings of the Board all the powers vested in
the Board except the power to fill vacancies in the Board, the power to change
the membership of or fill vacancies in said Committee and the power to change
the By-laws. The Board shall have the power at any time to change the membership

tion, shall have and may exercise the powers of the Board of Directors in the
management of the business and affairs of the Corporation, and may have power to

notice, but such notice may be given in writing, by mail, addressed to such
director or stockholder at such address as appears on the books of the
Corporation, and such notice shall be deemed to be given at the time when the
same shall be thus mailed. Whenever notice is required to be given, a waiver
thereof in writing signed by the person or persons entitled to said notice,
whether before or after the time stated therein, shall be deemed equivalent to
the giving of such notice.

the Board of Directors may elect and shall be signed by the Chairman of the
Board of Directors, the President, or a Vice-President and the Treasurer or an

new certificate or certificates, the Board of Directors may, in its discretion
and as a condition precedent to the issuance thereof, require the owner of such
lost or destroyed certificate or certificates, or his legal representative, to
advertise the same in such manner as it shall require and/or give the
Corporation a bond in such sum as it may direct as indemnity against any claim
that may be made against the Corporation with respect to the certificate alleged
