Section 617. Cumulative voting

The certificate of incorporation or the by-laws of any corporation may
  provide  that  in  all  elections  of directors of such corporation each
  member 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  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 for any two or more of them, as he may see fit, which
  right, when exercised, shall be termed cumulative voting.
