Whenever the commission deems it expedient, it may fund and refund its bonds and other obligations whether or not such bonds and obligations have matured. It may provide for the issuance, sale or exchange of refunding bonds for the purpose of redeeming or retiring any bonds (including the payment of any premium, duplicate interest or cash adjustment required in connection therewith) issued by the commission or issued by any other issuing body, the proceeds of the sale of which have been applied to any facility acquired by the commission or which are payable out of the revenues of any facility acquired by the commission. Bonds may be issued partly to refund bonds and other obligations then outstanding, and partly for any other purpose of the commission. All provisions of this compact applicable to the issuance of bonds are applicable to refunding bonds and to the issuance, sale or exchange thereof.
