(k) Deposit of jockey fees. No jockey, except when riding for his contract employer, shall be weighed out for any race unless there has been deposited for him or guaranteed to him with the racing secretary his fee for a losing mount in the race, and the failure to deposit for guarantee said fee for the engaged jockey may be cause for declaring the horse out of the race.
(l) Association to provide attendants. The association shall provide the only attendants who will be permitted to assist jockeys in weighing out. Such attendants shall be paid for their services by the association. A system of rotation of attendants shall be maintained.
