(from Ch. 32, par. 7.20)
Waiver of notice.
Whenever any notice whatever is required to be given under the
provisions of this Act or under the provisions of the articles of
incorporation or by-laws of any corporation, a waiver thereof in writing
signed by the person or persons entitled to such notice, whether before or
after the time stated therein, shall be deemed equivalent to the giving of
such notice. Attendance at any meeting shall constitute waiver of notice
thereof unless the person at the meeting objects to the holding of the meeting
because proper notice was not given.
