(a) The authority is authorized to fix rentals and other charges which the Department of Corrections shall pay to the authority for the use of each project or part thereof or combination of projects, to charge and collect the same, and to lease and make contracts with political subdivisions, agencies, and with the Department of Corrections with respect to the use by any institution or unit under its control of any project or part thereof. The rentals and other charges shall be fixed and adjusted in respect to the aggregate thereof from the project or projects for which a single issue of revenue bonds is issued so as to provide a fund sufficient with other revenues of the project or projects, if any, to pay:

(1) The cost of maintaining, repairing, and operating the project or projects, including reserves for extraordinary repairs and insurance and other reserves required by the resolution or trust indentures, unless the cost is otherwise provided for, which cost shall be deemed to include the expenses incurred by the authority on account of the project or projects for water, light, sewer, and other services furnished by other facilities at such institution; and

(2) The principal of the revenue bonds and the interest thereon as the same becomes due.

(b) The rentals contracted to be paid to the authority by the Department of Corrections or other contracting or leasing department, agency, or institution of the state under leases entered upon pursuant to this chapter shall constitute obligations of the state for the payment of which the good faith of the state is pledged. The rentals shall be paid as provided in the lease contracts from funds appropriated for such purposes by the terms of the Constitution of this state. It shall be the duty of the Department of Corrections or other contracting or leasing department, agency, or institution of the state to see to the punctual payment of all such rentals.

(c) In the event of any failure or refusal on the part of lessees to perform punctually any covenant or obligation contained in any lease entered upon pursuant to this chapter, the authority may enforce performance by any legal or equitable process against lessees; and consent is given for the institution of any such action.

(d) The authority shall be permitted to assign any rental due it by the lessees to a trustee or paying agent, as may be required by the terms of any trust indenture entered into by the authority.
