sufficient number of shares are cast against his removal which, if cumulatively
voted at an election of all the directors, or all the directors of a particular
class, if any, as the case may be, would be sufficient to elect at least one

director to fill the unexpired term of any director removed shall be deemed to
create a vacancy in the board.
