The authority is authorized to pledge and agree to use the said remaining proceeds for payment of the principal of, and interest on, all of the authorized bonds or for other retirement thereof, as may be provided in the proceedings under which such bonds are issued. If the proceeds from the sale or lease of the Kilby property are more than sufficient to pay, redeem or otherwise retire all of the bonds authorized in this chapter which shall be issued, the balance of such proceeds not needed for the retirement of such bonds may, at the election of the authority, be used to finish the construction of any of the facilities remaining uncompleted or to construct additional facilities.
