1. Any municipality which has revenue bonds issued pursuant to the provisions of sections 100.010 to 100.200 may issue refunding revenue bonds to provide funds to refund any or all of such revenue bonds, including payment of unpaid interest, premiums and other expenses connected therewith, whether the bonds to be refunded have or have not matured. The form of such refunding revenue bonds, and the terms under which such refunding revenue bonds may be issued, including the number of the years within which they are to be redeemed and their interest rate or rates, which interest rate or rates may be less than, the same, or greater than that of the revenue bonds being refunded, shall be specified by the ordinance, order, indenture or resolution authorizing the refunding bonds. Refunding under the provisions of this section may be effected by a private or public sale of the refunding revenue bonds, and the application of the proceeds to the purchase, redemption or payment of the revenue bonds to be refunded, or by an exchange of the refunding revenue bonds for the revenue bonds being refunded with the consent of the holder or holders of the revenue bonds being refunded. The refunding revenue bonds shall be paid solely from revenue received from the project or projects financed by the revenue bonds being refunded, and shall not be a general obligation of the municipality.

2. Any municipality proposing to issue refunding revenue bonds shall issue those bonds pursuant to the provisions of sections 100.010 to 100.200.
