business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a


quorum. Adjournment or adjournments of any annual or special meeting may be
taken, but any meeting at which directors are to be elected shall be adjourned
only from day to day, or for such longer periods not exceeding fifteen days
each, as may be directed by shareholders who are present in person or by proxy

shall be valid after eleven months from the date of its execution, unless a
longer time is expressly provided therein, but in no event shall a proxy, unless
coupled with an interest, be voted on after three years from the date of its
execution. Elections for directors shall be by cumulative voting. Upon demand
made by a shareholder at any election for the directors before the voting
begins, the election shall be by ballot. No share shall be voted at any meeting
upon which any installment is due and unpaid. The original share transfer book,

meeting on the request of one or more shareholders or proxies, the majority of
shares present and entitled to vote shall determine whether one or three judges
are to be appointed. On request of the Chairman of the meeting, or of any
shareholder or his proxy, the judge(s) shall make a report in writing of any

entitled to cast at the particular meeting. At any time, upon written request of
any person or persons who have duly called a special meeting, it shall be the
duty of the Secretary to fix the date of the meeting to be held not less than
ten nor more than sixty days after receipt of the request, and to give due
notice thereof. If the Secretary shall neglect or refuse to fix the date of the
meeting and give notice thereof, the person or persons calling the meeting may
