(a) Method--Written notice required to be given to any person under the provisions of this act or by the articles or by-laws of an incorporated institution may be given to such person, either personally or by sending a copy thereof through the mail, or by telegram, charges prepaid, to his address appearing on the books of the institution, or supplied by him to the institution for the purpose of notice. If the notice is sent by mail or by telegraph, it shall be deemed to have been given to the person entitled thereto when deposited in the United States mail or with a telegraph office for transmission to such person. If such notice is of a meeting, it shall specify the place, day and hour of the meeting and, in the case of a special meeting of shareholders or trustees, the general nature of the business to be transacted.

(b) Waiver--Any written notice required to be given under the provisions of this act or the articles or by-laws of an incorporated institution need not be given if there is a waiver thereof in writing, signed by the person entitled to such notice, whether before or after the time when the notice would otherwise be required to be given. If the notice is of a meeting other than a special meeting of shareholders or trustees, neither the business to be transacted at, nor the purpose of, the meeting need be specified in the waiver of notice.

(c) Effect of attendance at meeting--Attendance of a person, either in person or by proxy, 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 to the transaction of any business because the meeting was not lawfully called or convened.

(d) Amendment of resolution or plan included in notice--If the language of a proposed resolution or a proposed plan requiring approval by shareholders or trustees is included in a written notice of a meeting of shareholders or trustees, the shareholders' or trustees' meeting considering the resolution or plan may adopt it with such clarifying or other amendments as do not enlarge its original purpose without further notice to shareholders or trustees not present in person or by proxy.
