(A) If less than six separate entries start, permit holders may prohibit show wagering. In all races with less than five entries which start, they may prohibit both place and show wagering. If, after betting has opened, a late scratch reduces the number of betting interests to five or less, the show pool may be canceled at the discretion of the permit holder and the gross show pool refunded. If late scratches reduce the betting interests to four or less, the place and show pools may be canceled at the discretion of the permit holder and the gross place and show pools refunded.
(B) In the case of stakes with less than five entries which start, permit holders, may at their option provide that there shall be no wagering; and in such case an additional race with wagering may be added to the program. However, the stewards in any race may waive the requirement that there must be a place or show pool.
(C) In races with six or less wagering interests that start, permit holders may prohibit exotic wagering that requires more than two horses in one race to calculate a payoff. In races with less than five entries that start, all exotic wagering may be prohibited.
(D) If a late scratch or scratches reduce the numbers of wagering interests to six or less, the exotic pools requiring more than two horses to complete a payoff may be canceled at the discretion of the permit holder and the gross exotic pool refunded. If the number of wagering interests is reduced to five or less, the permit holder may cancel any exotic pool that requires more than one horse in one race to calculate a payoff and refund the gross exotic pool to holders of such tickets.
(E) A permit holder with the consent of the stewards, may bar wagering on any horse or entry in any race, heat or dash. In such event a public announcement shall be made prior to the acceptance of any wagers with respect to such race, heat or dash. Under such circumstances the horse or entry barred shall be considered for the purpose of such wagering not to have been a participant in such race. A horse or entry barred in one heat or dash of a race is not barred in subsequent heats or dashes of the same race unless the permit holder, with the consent of the stewards, again determines to do so and suitable public announcement is made thereof.
