  supervise each running race meeting conducted pursuant to  sections  two

  shall be the official steward of the board, one shall  be  appointed  by
  the  jockey club or by the national steeplechase and hunt association as
  may be appropriate, and  one  shall  be  appointed  by  the  corporation
  conducting  such  race meeting. Such stewards shall exercise such powers
  and perform such duties at each race meeting as may be prescribed by the
  rules of the state racing and wagering  board.  During  the  absence  or
  inability to act of an official steward of the board, or in the event of
  the  failure  or  inability to appoint either of the other two stewards,
  the powers and duties of such steward shall be exercised  and  performed
  without  compensation  by  a member of the board designated by the board
  for that purpose.
