  force  of  the  village  of  Hempstead,  in the county of Nassau, who is
  contributing to  the  retirement  system  under  section  three  hundred
  eighty-four of this chapter, shall continue in service after twenty-five
  years  of  total  creditable  police  service under such section in such
  force, he shall receive, upon retirement, in addition to the  amount  of
  any  retirement  allowance  he  would  otherwise be entitled to receive,
  pursuant to the applicable provisions of  this  chapter,  an  additional
  pension for such service of one-sixtieth of his final average salary for
  each  completed  additional year of service after twenty-five years. The
  participating employer in the case of any  policeman  eligible  for  the
  additional  pension  benefit  prescribed  by  this  section  shall  make
  additional contributions to  the  appropriate  fund  of  the  retirement

  entitled  to  additional  pension  credit  under  this  section shall be
  terminated and he shall be retired on the  first  day  of  the  calendar
  month  next  succeeding his attainment of age sixty-two provided however
  that in the case of the chief  of  such  force,  his  service  shall  be
  terminated  and  he  shall  be  retired on the first day of the calendar
  month next succeeding his attainment of age sixty-five.  Notwithstanding
  the  foregoing,  during  the  period  terminating  March   thirty-first,
  nineteen  hundred seventy-four, such chief shall be retired on the first
  day of the calendar month next succeeding his attainment of age seventy;
  provided that  service  rendered  by  such  chief  after  attaining  age
  sixty-five shall not be used to provide additional benefits, except that
  the  salary  paid  for  such  service  may be used in the computation of
  benefits.
    c. The provisions of subdivisions f, g, and h of section three hundred
  eighty-four of this chapter shall not be applicable to  the  village  of
