to receive payment of any such dividend or other distribution, or any such
allotment of rights, or to exercise rights with respect to any such change,
conversion, or exchange of capital shares and, in such case, only shareholders
of record on the date so fixed shall be entitled to receive payment of such
dividend or other distribution, or allotment of rights, or exercise such rights,
as the case may be, notwithstanding the transfer of any shares on the books of

provided in the preceding paragraph of this Section 2.6, the Board of Directors,

attendance of a person at a shareholders meeting, in person or by proxy,
constitutes a waiver of notice of the meeting, except when the shareholder
attends the meeting for the express purpose of objecting, at the beginning of
the meeting, to the transaction of any business because the meeting was not
lawfully called or convened.

         3.6 Voting Lists. The corporation's officer or the agent having charge
of its share transfer books shall prepare and certify a complete list of the
