Section 812. Waivers of Notice.
(a) Whenever any written notice is required to be given under the provisions of the Bylaws or the Nonprofit Corporation Law of 1972, 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. Except as otherwise required by this section, neither the business to be transacted at nor the purpose of a meeting need be specified in the waiver of notice of such meeting. In the case of a special meeting of Delegates such waiver of notice shall specify the general nature of the business to be transacted.
(b) Attendance of a person at any meeting shall constitute a waiver of notice of such meeting, except where a person attends a 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.
