               owner of an interest in the Seller's Interest elects to have such

thereof in its entirety and inserting in its place the following:

               The Seller's Certificate shall represent the ownership interest
               in the remainder of the Trust Assets not allocated pursuant to
               this Agreement or any Supplement to the Certificateholders'
               Interest, including the right to receive Collections with respect
               to the Receivables and other amounts at the times and in the
               amounts specified in this Agreement or any Supplement to be paid

               Seller's Certificate, shall represent the "Seller's Interest";

               Agreement and any Supplement.

               SECTION 7.  Amendment of Section 6.01.  Section 6.01 of the
                           -------------------------

               Seller's Interest be (i) an uncertificated interest or (ii)
               evidenced by a certificate. If the Bank or any Additional Seller

               Additional Seller elects to have its interest in the Seller's
               Interest be evidenced by a certificate, the Bank Certificate will
               be issued in registered form, substantially in the form of
               Exhibit A and shall upon issue be executed and delivered by the
               Bank to the Trustee for authentication and redelivery as provided
               in Section 6.02. The Trustee shall keep with the books and
               records of the Trust a register, in book-entry form, of each
               Person owning any uncertificated interest in the Seller's
               Interest.

               surrender such interest in exchange for a Supplemental
               Certificate in accordance with the requirements and subject to
               the satisfaction of the conditions in this Section 6.03(c), and
               will instruct the Trustee in writing to register such exchange on
               the books and records of the Trust.

                    Notwithstanding anything in this Agreement to the contrary
               and subject to the related Supplement, any Holder of a
               Supplemental Certificate that is an Affiliate of the Bank may
               elect at any time, by written notice to the Trustee, to have its
               interest in the Seller's Interest be (i) an uncertificated
               interest or (ii) evidenced by a certificate. If the Holder of a
               Supplemental Certificate elects to have its interest in the
               Seller's Interest be uncertificated, it shall deliver to the

               and records of the Trust registering such uncertificated interest
               in the Seller's Interest. If the owner of any such uncertificated
               interest elects to have its interest in the Seller's Interest be
               evidenced by a certificate, a Supplemental Certificate will be
