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 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.
