Each trustee, except ex officio trustees, shall serve for a term expiring at the end of the term of the officer making the appointment. In the event of a vacancy occurring in the office of a trustee by death, resignation, termination of membership on the board of trustees of the city university of New York, or otherwise, a successor shall be chosen in the same manner as was the trustee whose office became vacant, to serve for the balance of the unexpired term.
