(1) Parimutuel tickets may not be sold by anyone other than an association licensed to conduct parimutuel wagering.

(2) No parimutuel ticket may be sold on a race for which wagering has already been closed and the association is not responsible for ticket sales entered into but not completed by issuance of a ticket before the parimutuel system is closed for wagering.

(3) Parimutuel tickets may be exchanged or cancelled prior to the running of a race based upon the written policies of the association. Such policies must be filed with the commission.

(4) Payment on winning parimutuel wagers will be made on the basis of the order of finish as posted and declared "official." Any subsequent change in the order of finish or award of purse money as may result from a subsequent ruling by the stewards or commission will in no way affect the parimutuel payoff. If an error in the posted order of finish or payoff figures is discovered, the official order of finish or payoff prices may be corrected and an announcement concerning the change will be made to the public.

(5) The association has no obligation to enter a wager into a betting pool if unable to do so due to equipment failure.

(6) No person under the age of eighteen may purchase or cash any parimutuel ticket. No employee of the association may knowingly sell to or cash for a person under the age of eighteen any parimutuel ticket. Unattended persons under the age of eighteen are not permitted in wagering areas.
