          NOW THEREFORE, in consideration of the premises and the agreements

          The Transferor and the Owner Trustee acknowledge and agree that the
     purpose of this Article XI is to facilitate compliance by the Transferor

     the Commission. The Transferor shall

     not exercise its right to request delivery of information or other
     performance under these provisions other than in good faith, or for
     purposes other than the Transferor's compliance with the Securities Act,
     the Securities Exchange Act and the rules and regulations of the Commission
     thereunder (or the provision in a private offering of disclosure comparable
     to that required under the Securities Act). The Owner Trustee agrees to
     cooperate in good faith with any reasonable request by the Transferor for
     information regarding the Owner Trustee which is required in order to
     enable the Transferor to comply with the provisions of Regulation AB,
     including, without limitation, Items 1103(a)(1), 1109(a), 1109(b), 1117 and
     1119 of Regulation AB as it relates to the Owner Trustee or to the Owner
     Trustee's obligations under this Agreement.

          Section 11.02 Information to Be Provided by the Owner Trustee.

          For so long as the Transferor is required to report under Regulation
     AB, the Owner Trustee shall, as promptly as practicable, notify the
     Transferor, in writing, of: (i) the commencement of, a material development
     in or, if applicable, the termination of, any and all legal proceedings
     against the Owner Trustee or any and all proceedings of which any property
     of the Owner Trustee is the subject, that is material to the noteholders;
     and (ii) any such proceedings known to be contemplated by governmental
     authorities. The Owner Trustee shall also notify the Transferor, in
     writing, as promptly as practicable following notice to or discovery by a
     Responsible Officer of the Owner Trustee of any material changes to
     proceedings described in the preceding sentence. In addition, the Owner
     Trustee will furnish to the Transferor, in writing, the necessary
     disclosure regarding the Owner Trustee describing such proceedings required
     to be disclosed under Item 1117 of Regulation AB, for inclusion in reports
     filed by or on behalf of the Transferor pursuant to the Exchange Act.

          For so long as the Transferor is required to report under Regulation
     AB, the Owner Trustee shall (i) on or before the fifth Business Day of each
     January, April, July and October, or as otherwise requested by the
     Transferor, provide to the Transferor such information regarding the Owner
     Trustee as is required for the purpose of compliance with Items 1109(a),
     1109(b) and 1119 of Regulation AB; provided, however, the Owner Trustee
     shall not be required to provide such information in the event that there
     has been no change to the information previously provided by the Owner
     Trustee to the Transferor; and (ii) as promptly as practicable following
     notice to or discovery by a Responsible Officer of the Owner Trustee of any
     changes to such information, provide to the Transferor, in writing, such
     updated information. Such information shall include, at a minimum:

          (A) the Owner Trustee's name and form of organization;

          (B) a description of the extent to which the Owner Trustee has had
     prior experience serving as a trustee for asset-backed securities
     transactions involving credit card receivables; and


                                        2

<PAGE>

          (C) a description of any affiliation between the Owner Trustee and any
     of the following parties to a Securitization Transaction, as such parties
     are identified to the Owner Trustee by the Transferor in writing in advance
     of such Securitization Transaction:

          (1)  the sponsor;

          (2)  any depositor;

          (3)  the issuing entity;

          (4)  any servicer;

          (5)  any other trustee;

          (6)  any originator;

          (7)  any significant obligor;

          (8)  any enhancement or support provider; and

          (9)  any other material party related to any Securitization
               Transaction.

          In addition, the Owner Trustee shall provide a description of whether
     there is, and if so the general character of, any business relationship,
     agreement, arrangement, transaction or understanding between the Owner
     Trustee and any above-listed party that is entered into outside the
     ordinary course of business or is on terms other than would be obtained in
     an arm's length transaction with an unrelated third party, apart from the
     Securitization Transactions, that currently exists or that existed during
     the past two years and that is material to an investor's understanding of
     the asset-backed securities.

          SECTION 3. Effectiveness. The amendments provided for by this
Amendment shall become effective upon:

          (a) confirmation that the Rating Agency Condition shall have been
satisfied;

          (b) receipt by the Owner Trustee and the Indenture Trustee of an
Officer's Certificate from the Transferor to the effect that the Transferor
reasonably believes that the terms of this Amendment will not materially and
adversely affect the interest of any Noteholder or cause the Trust to be to fail
to be treated as a "qualified special purpose entity" as defined in FAS 140 (as
successor statement to FASB Statement No. 125);

          (c) receipt by the Owner Trustee and the Indenture Trustee of an
opinion of Counsel addressed to the Owner Trustee and the Indenture Trustee to
the effect that the terms of this Amendment will not cause the Trust to be
classified as an association (or a publicly traded partnership) taxable as a
corporation for federal income tax purposes; and


                                        3

Rating Agency of counterparts of this Amendment, duly executed by the parties
hereto.

          SECTION 4. Trust Agreement in Full Force and Effects as Amended.
Except as specifically amended or waived hereby, all of the terms and conditions
of the Trust Agreement shall remain in full force and effect. All references to
the Trust Agreement in any document or instrument shall be deemed to mean the
Trust Agreement as amended by this Amendment. This Amendment shall not
constitute a novation of the Trust Agreement, but shall constitute an amendment
thereof. The parties hereto agree to be bound by the terms and obligations of
the Trust Agreement, as amended by this Amendment, as though the terms and
obligations of the Trust Agreement were set forth herein.

          SECTION 5. Counterparts. This Amendment may be executed in any number
of counterparts and by separate parties hereto on separate counterparts, each of
which when executed shall be deemed an original, but all such counterparts taken
together shall constitute one and the same instrument.

          SECTION 6. Governing Law. THIS AMENDMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE
PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

          SECTION 7. Defined Terms and Section References. Capitalized terms
used herein and not otherwise defined shall have the meaning assigned to such
terms in the Trust Agreement. All Sections or subsections references herein
shall mean Sections or subsections of the Trust Agreement, except as otherwise
