Section 618. Cumulative voting

The  certificate  of incorporation of any corporation may provide that
  in all elections of directors of such corporation each shareholder shall
  be entitled to as many votes as shall equal the number of  votes  which,
  except for such provisions as to cumulative voting, he would be entitled
  to  cast  for  the  election  of  directors  with  respect to his shares
  multiplied by the number of directors to be elected,  and  that  he  may
  cast  all  of  such  votes  for a single director or may distribute them
  among the number to be voted for, or any two or more of them, as he  may
  see fit, which right, when exercised, shall be termed cumulative voting.
