All moneys on deposit in the debt service fund shall be held in trust in such debt service fund for the benefit of holders of the Bonds, shall be applied solely for the payment of principal of and sinking fund installment, redemption premium, if any, and interest on the Bonds and shall not be used for any other purpose. The holders of the Bonds shall have a security interest in and lien upon all such moneys.(b) The Authority shall, by its resolution authorizing Bonds to be issued on or after July 1, 1993 (other than to refund or to continue the refunding of Bonds issued prior to July 1, 1993), establish a debt service fund which shall be separate from any such fund for Bonds issued prior to July 1, 1993 (including Bonds issued to refund or to continue the refunding of those prior Bonds). Such a separate debt service fund shall secure only Bonds issued on or after July 1, 1993 (other than Bonds to refund or to continue the refunding of Bonds issued prior to July 1, 1993). The debt service fund established with respect to Bonds issued prior to July 1, 1993 (or to refund or to continue the refunding of Bonds issued prior to July 1, 1993) shall not secure Bonds issued on or after July 1, 1993 (other than Bonds issued to refund or to continue the refunding of Bonds issued prior to July 1, 1993).
