         WHEREAS, the Trustee is willing to accept such designation and

                  3. Conveyance of Receivables.

                  A. Chase USA does hereby transfer, assign, set-over and
         otherwise convey to the Trustee on behalf of the Trust for the benefit
         of the Certificateholders, without recourse on and after the Addition
         Date, all right, title and interest of Chase USA in and to the
         Receivables now existing and hereafter created in the Additional
         Accounts designated hereby, all monies due or to become due with
         respect thereto (including all Finance Charge Receivables) and all
         proceeds of such Receivables, Recoveries, Interchange, Insurance
         Proceeds relating to such Receivables and the proceeds of any of the
         foregoing.

         record and file, at its own expense, a financing statement with respect
         to the Receivables now existing and hereafter created in the Additional
         Accounts designated hereby (which may be a single financing statement
         with respect to all such Receivables) for the transfer of accounts as
         defined in Section 9-102 of the UCC as in effect in the State of New
         York meeting the requirements of applicable state law in such manner
         and such jurisdictions as are necessary to perfect the assignment of
         such Receivables to the Trustee on behalf of the Trust for the benefit
         of the Certificateholders (the "Secured Party"), and to deliver a
         file-stamped copy of such financing statement or other evidence of such
         filing (which may, for purposes of this Section 3, consist of telephone
         confirmation of such filing) to the Trustee on or prior to the date of
         this Assignment.

                  C. It is the intention of the parties hereto that all
         transfers of Receivables to the Trust pursuant to this Assignment be
         subject to, and be treated in accordance with, the Delaware Act and
         each of the parties hereto agrees that this Assignment has been entered
         into by the parties hereto in express reliance upon the Delaware Act.
         For purposes of complying with the requirements of the Delaware Act,
         each of the parties hereto hereby agrees that any property, assets or
         rights purported to be transferred, in whole or in part, by Chase USA
         pursuant to this Assignment shall be deemed to no longer be the
         property, assets or rights of Chase USA. The parties hereto acknowledge
         and agree that each such transfer is occurring in connection with a
         "securitization transaction" within the meaning of the Delaware Act.

                  D. In connection with such transfer, Chase USA further agrees,
         at its own expense, on or prior to the date of this Assignment to
         indicate in its computer files that Receivables created in connection
         with the Additional Accounts designated hereby have been transferred to
         the Trust pursuant to this Assignment for the benefit of the
         Certificateholders.

                  E. Chase USA hereby grants to the Secured Party a security
         interest in all of Chase USA's right, title and interest in, to and
         under the Receivables now existing and hereafter created in the
         Additional Accounts designated hereby, all monies due or to become due
         with respect to such Receivables, Insurance Proceeds relating to such
         Receivables, Recoveries, Interchange and the proceeds to any of the
         foregoing to secure a loan in an amount equal to the unpaid principal
         amount of the Investor Certificates issued or to be issued pursuant to
         the Pooling and Servicing Agreement and the interests accrued at the
         related Certificate Rates, and this Assignment shall constitute a
         security agreement under applicable law. Chase USA shall execute
         continuation statements and provide other further assurances to
         maintain the perfection and priority of such security interest of the
         Secured Party.

                  4. Acceptance by Trustee. The Trustee hereby acknowledges its
         acceptance on behalf of the Trust for the benefit of the
         Certificateholders of all right, title and interest previously held by
         Chase USA in and to the Receivables now existing and hereafter
         created, and declares that it shall maintain such right, title and
         interest, upon the Trust herein set forth, for the benefit of all
         Certificateholders.

                  5. Representations and Warranties of Chase USA. Chase USA
         hereby represents and warrants to the Secured Party as of the Addition
         Date:

                  A. Legal, Valid and Binding Obligation. This Assignment
         constitutes a legal, valid and binding obligation of Chase USA
         enforceable against Chase USA in accordance with its terms, except as
         such enforceability may be limited by applicable bankruptcy,
         insolvency, reorganization, moratorium or other similar laws now or
         hereafter in effect affecting the enforcement of creditors' rights in
         general and the rights of creditors of banking associations and except
         as such enforceability may be limited by general principles of equity
         (whether considered in a suit at law or in equity).

                  B. Eligibility of Accounts and Receivables. Each Additional
         Account designated hereby is an Eligible Account and each Receivable
         in such Additional Account is an Eligible Receivable.

                  C. Selection Procedures. No selection procedures believed by
         Chase USA to be materially adverse to the interests of the Investor
         Certificateholders were utilized in selecting the Additional Accounts
         designated hereby from the available Eligible Accounts in the Bank
         Portfolio.

                  D. Insolvency. Chase USA is not insolvent and, after giving
         effect to the conveyance set forth in Section 3 of this Assignment,
         will not be insolvent.

                  E. Transfer. This Assignment constitutes either: (i) a valid
         transfer and assignment to the Trust of all right, title and interest
         of Chase USA in and to Receivables now existing and hereafter created
         in the Additional Accounts designated hereby, and all proceeds (as
         defined in the UCC) of such Receivables and Insurance Proceeds relating
         thereto, and such Receivables and any proceeds thereof and Insurance
         Proceeds relating thereto will be held by the Secured Party free and
         clear of any Lien of any Person claiming through or under Chase USA or
         any of its Affiliates except for (x) Liens permitted





                                        4


<PAGE>



         under subsection 2.5(b) of the Pooling and Servicing Agreement, (y) the
         interest of the holder of the Transferor Certificate and (z) Chase
         USA's right to receive interest accruing on, and investment earnings in
         respect of, the Finance Charge Account and the Principal Account as
         provided in the Pooling and Servicing Agreement; or (ii) a valid and
         continuing security interest (as defined in the UCC) in the Receivables
         now existing or hereafter created in the Additional Accounts in favor
         of the Secured Party, the proceeds (as defined in the UCC) thereof and
         Insurance Proceeds relating thereto, upon the conveyance of such
         Receivables to the Trust, which security interest is prior to all other
         Liens, and is enforceable against creditors of and purchasers from
         Chase USA, and which will be enforceable with respect to the
         Receivables thereafter created in respect of Additional Accounts
         designated hereby, the proceeds (as defined in the UCC) thereof and
         Insurance Proceeds relating thereto, upon such creation; and (iii) if
         this Assignment constitutes the grant of a security interest to the
         Secured Party in such property, upon the filing of a financing
         statement described in Section 3 of this Assignment with respect to the
         Additional Accounts designated hereby and in the case of the
         Receivables of such Additional Accounts thereafter created and the
         proceeds (as defined in the UCC) thereof, and Insurance Proceeds
         relating to such Receivables, upon such creation, the Secured Party
         shall have a first priority perfected security interest in such
         property (subject to Section 9-315 the UCC as in effect in the State of
         Delaware), except for Liens permitted under subsection 2.5(b) of the
         Pooling and Servicing Agreement. Chase USA has caused or will have
         caused, within ten days, the filing of all appropriate financing
         statements in the proper filing office in the appropriate jurisdictions
         under applicable law in order to perfect the security interest in the
         Receivables granted to the Secured Party hereunder. The Receivables
         constitute "accounts" within the meaning of the applicable UCC.

                  F. Other Liens. Other than the security interest granted to
         the Secured Party pursuant to this Assignment, Chase USA has not
         pledged, assigned, sold, granted a security interest in, or otherwise
         conveyed any of the Receivables. Chase USA has not authorized the
         filing of and is not aware of any financing statements against Chase
         USA that include a description of collateral covering the Receivables
         other than any financing statement (i) relating to the security
         interest granted to the Secured Party hereunder, (ii) that has been
         terminated,

         forth in Section 2.4(d) of the Pooling and Servicing Agreement shall be

         Section 5 with respect to any Receivable.

                  more senior officer substantially in the form of Schedule 2
                  hereto, certifying that (i) all requirements set forth in
                  Section 2.6 of the Pooling and Servicing Agreement for
                  designating Additional Accounts and conveying the Principal
                  Receivables of such Account, whether now existing or hereafter
                  created, have been satisfied and (ii) each of the
                  representations and warranties made by Chase USA in Section 5
                  is true and correct as of the Addition Date. The Trustee may
                  conclusively rely on such Officer's Certificate, shall have no
                  duty to make inquiries with regard to the matters set forth
                  therein, and shall incur no liability in so relying.

                           B. Opinion of Counsel. Chase USA shall have delivered
                  to the Trustee an Opinion of Counsel with respect to the

                  8. Survival. The representations, warranties and covenants
         of the parties hereto shall survive the assignment of the Receivables
         pursuant to this Assignment and the termination of this Assignment, and

         contrary in this Assignment, the representations and warranties of the
         Chase USA herein shall not survive after the tenth (10th ) anniversary
         of the Addition Date.

                  9. Waivers and Amendments. This Assignment may be amended,
         superseded, canceled, renewed or extended and the terms hereof may be
         waived, only by a written instrument signed by authorized
         representatives of the parties or, in the case of a waiver, by an

         partial exercise of any such right, power or privilege, preclude any

                  12. Tax Treatment. Nothing in this Assignment shall be deemed
