Section 711. Notice of meetings of the board

(a)  Unless otherwise provided by the by-laws, regular meetings of the
  board may be held without notice if the time and place of such  meetings
  are  fixed  by  the  by-laws or the board. Special meetings of the board
  shall be held upon notice to the directors.
    (b) The by-laws may prescribe what shall constitute notice of  meeting
  of  the  board.  A  notice,  or  waiver  of notice, need not specify the
  purpose of any regular or special meeting of the board, unless  required
  by the by-laws.
    (c)  Notice  of a meeting need not be given to any alternate director,
  nor to any director who submits a signed waiver of notice whether before
  or after the meeting, or who attends  the  meeting  without  protesting,
  prior thereto or at its commencement, the lack of notice to him.
    (d)  A  majority  of the directors present, whether or not a quorum is
  present, may adjourn any meeting to  another  time  and  place.  If  the
  by-laws  so provide, notice of any adjournment of a meeting of the board
  to another time or place shall be given to the directors  who  were  not
  present  at  the time of the adjournment and, unless such time and place
  are announced at the meeting, to the other directors.
