(d) The design of double exacta tickets shall be clearly and immediately distinguishable from other pari-mutuel tickets.
(2) Should any horse be scratched or declared a nonstarter in the second half of the double exacta after the first half of the double exacta has been raced, all tickets combining the scratched horse with the winning combination of the first half shall become consolation tickets and shall be paid at a price per dollar bet determined as follows: the net double exacta pool (gross pool less commission) shall be divided by the total purchase price of all double exacta tickets combining the winners of the first half of the double exacta, and the result obtained shall constitute the consolation prize to be paid per dollar bet.
