Notice of shareholders' meetings.

Written notice stating the place, day and hour of the meeting and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered not less than ten nor more than fifty days before the date of the meeting, either personally or by mail, at the direction of the president, the secretary or the officer or persons calling the meeting, to each shareholder of record entitled to vote at the meeting. If mailed, the notice shall be deemed to be delivered when deposited in the United States mail addressed to the shareholder at his address as it appears on the stock transfer books of the corporation, with postage thereon prepaid. Attendance of a shareholder in person or by proxy at a meeting constitutes a waiver of notice of the meeting, except where a shareholder attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened.
