(1) No vendor shall receive less vending machine income than he/she was receiving during the calendar year 1973 as a direct result of any limitation imposed on such income by this section.

(3) The department shall disburse vending machine income to vendors on at least a quarterly basis.

(4) Vending machine income from vending machines on federal property received by the department and not eligible for distribution to blind vendors under the provisions of this section shall be retained by the department.

(5) Vending machine income which is retained under subsection (4) of this section shall be used by the department for the establishment and maintenance of retirement or pension funds, for health insurance contributions, and for the provision of paid sick leave and vacation time, for vendors, if it is so determined by a majority vote of all vendors after the department has provided to each vendor information on all matters relevant to such purposes. Any vending machine income not necessary for such purposes shall be used by the department for the maintenance and replacement of equipment, the purchase of new equipment, management services, and assuring a fair minimum return to vendors.
