Revenues.

(1) The authority is hereby authorized to fix and to collect fees, rents, loan payments, and charges for the use of any project or projects and any part or section thereof. The authority may require that the health facility operating any project or any part thereof financed or refinanced under this chapter or the lessee of any project or part thereof shall operate, repair, and maintain the project and bear the cost thereof and other costs of the authority in connection with the project or projects financed or refinanced as may be provided in the agreement of lease, loan agreement, or other contract with the authority, in addition to other obligations imposed under such agreement or contract.

(2) The fees, rents, loan payments, and charges shall be so fixed as to provide a fund sufficient to pay the principal of, and the interest on, such bonds as the same shall become due and payable and to create reserves, if any, deemed by the authority to be necessary for such purposes. The fees, rents, loan payments, charges, and all other revenues and proceeds derived from the project or projects in connection with which the bonds of any issue shall have been issued, except such part thereof as may be necessary for such reserves or any expenditures as may be provided in the resolution authorizing the issuance of such bonds or in the trust agreement securing the same, shall be set aside at such regular intervals as may be specified in such resolution or such trust agreement in a sinking fund which is hereby pledged to, and charged with, the payment of the principal of and the interest on such bonds as the same shall become due and the redemption price or the purchase price of bonds retired by call or purchase as therein provided. Such pledge shall be valid and binding from the time when the pledge is made. The fees, rents, loan payments, charges, and other revenues and moneys so pledged and thereafter received by the authority shall immediately be subject to the lien of such pledge without any physical delivery thereof or further act, and the lien of any such pledge shall be valid and binding as against all parties having claims of any kind in tort, contract, or otherwise against the authority, irrespective of whether such parties have notice thereof. The use and disposition of money to the credit of such sinking fund shall be subject to the provisions of the resolution authorizing the issuance of such bonds or of such trust agreement. Except as may otherwise be provided in the resolution or the trust agreement, the sinking fund shall be a fund for all such bonds without distinction or priority of one over another.
