Collateral Depositor (or the Cash Collateral Account and each Additional Cash
Collateral Account, as applicable) shall mean proportionately according to a
share or interest in favor of the Cash Collateral Depositor (or the Cash
Collateral Account) equal to the percentage equivalent of a fraction, the
numerator of which is the Invested Amount (before giving effect to any
Additional Issuance with respect to which the Cash Collateral Depositor has not
provided additional Series Enhancement) and the denominator of which is the
Invested Amount (after giving effect to all Additional Issuances through such
date of determination) and a share or interest in favor of each Additional Cash
Collateral Depositor (or the related Additional Cash Collateral Account) equal
to the percentage equivalent of a fraction, the numerator of which is the
increase in the Invested Amount with respect to which such Additional Cash
Collateral Depositor has provided additional Series Enhancement as a result of
the related Additional Issuance and the denominator of which is the Invested
Amount (after giving effect to all Additional Issuances through such date of
determination).

under the laws of the United States or any one of the states thereof, including
the District of Columbia (or a domestic branch of a foreign bank), which at all

Collateral Amount shall have the meaning stated above except that such
institution is required, with respect to Standard & Poor's, to have either a
long-term unsecured debt rating of at least A or a certificate of deposit rating
of at least A-1. However, any deposit account established exclusively for the
deposit of all or a portion of the Initial Class B Collateral Amount shall not
otherwise be considered to be separate from the deposit account containing the
related amount of the Initial Shared Collateral Amount and the two together
shall constitute one Cash Collateral Account for the purposes of this

aggregate reimbursement of Investor Charge-Offs as of such last day.

                  (b) Each of the Sellers hereby represents and warrants to the
Trustee as of the date of this Series Supplement that, on or prior to the date
of this Series Supplement, the conditions set forth in Section 13.01(a) of the
Agreement have been satisfied with respect to the amendment set forth in Section

                  Section 3.01. Servicing Compensation. A monthly servicing fee
(the "Servicing Fee") shall be payable to the Servicer, in arrears, on each
Distribution Date in respect of any Due Period (or portion thereof) occurring
prior to the earlier of the first Distribution Date following the Termination
Date and the first Distribution Date on which the Invested Amount and the CCA
Invested Amount, if any, are zero, in the aggregate amount specified below.

                  On each Distribution Date, Servicer Interchange with respect
to the related Due Period that is on deposit in the Collection Account shall be
withdrawn from the Collection Account and paid to the Servicer in payment of a
portion of the Servicing Fee payable by the Series 1998-3 Certificateholders
with respect to such Due Period.

                  The share of the Servicing Fee allocable to the Class A
Certificateholders (after giving effect to the distribution of Servicer
Interchange, if any, to the Servicer) with respect to any Distribution Date (the

(a) the Net Servicing Fee Rate, (b) the sum of the Invested Amount and the CCA
Invested Amount, if any, as of the last day of the Due Period second preceding
such Distribution Date and (c) the Class A Invested Percentage with respect to
such Distribution Date; provided, however, with respect to the first
Distribution Date, the Class A Monthly Servicing Fee shall be equal to the
Servicing Fee accrued on the Class A Initial Invested Amount at the Net
Servicing Fee Rate for the period from the Closing Date to but excluding the
first Distribution Date, calculated on the basis of a 360-day year of twelve
30-day months and provided further, that with respect to the first Distribution
Date of the related Due Period in which an Additional Issuance Date occurs the
Class A Monthly Servicing Fee shall be increased by an amount equal to the
product of (a) the Net Servicing Fee Rate, (b) a fraction, the numerator of
which is 30 minus the actual number of days in the period from and including the
seventh day of the calendar month in which such Additional Issuance Date occurs
to but excluding such Additional Issuance Date and the denominator of which is
360, times (c) the increase in the Invested Amount after giving effect to the
related Additional Issuance and (d) the Class A Invested Percentage with respect
to such Distribution Date. The share of the Servicing Fee allocable to the Class
B Certificateholders (after giving effect to the distribution of Servicer
Interchange, if any, to the

Fee") shall be equal to one-twelfth of the product of (a) the Net Servicing Fee
Rate, (b) the sum of the Invested Amount and the CCA Invested Amount, if any, as
of the last day of the Due Period second preceding such Distribution Date and
(c) the Class B Invested Percentage with respect to such Distribution Date;
provided, however, with respect to the first Distribution Date, the Class B
Monthly Servicing Fee shall be equal to the Servicing Fee accrued on the Class B
Initial Invested Amount at the Net Servicing Fee Rate for the period from the
Closing Date to but excluding the first Distribution Date, calculated on the
basis of a 360-day year of twelve 30-day months and provided further, that with
respect to the first Distribution Date of the related Due Period in which an
Additional Issuance Date occurs, the Class B Monthly Servicing Fee shall be
increased by an amount equal to the product of (a) the Net Servicing Fee Rate,
(b) a fraction, the numerator of which is 30 minus the actual number of days in
the period from and including the seventh day of the calendar month in which
such Additional Issuance Date occurs to but excluding such Additional Issuance
Date and the denominator of which is 360, times (c) the increase in the Invested
Amount after giving effect to the related Additional Issuance and (d) the Class
B Invested Percentage with respect to such Distribution Date. The share of the
Servicing Fee allocable, on a pro rata basis, to the Cash Collateral Depositor
and each Additional Cash Collateral Depositor (after giving effect to the
distribution of Servicer Interchange, if any, to the Servicer) with respect to
any Distribution Date relating to the Early Amortization Period, following the
Distribution Date on which the Class A Invested Amount and the Class B Invested
Amount are paid in full (the "CCA Monthly Servicing Fee"), shall be equal to
one-twelfth of the product of (a) the Net Servicing Fee Rate and (b) the CCA
Invested Amount, if any, as of the last day of the Due Period second preceding
such Distribution Date.

                  On each Distribution Date, the Sellers shall pay a portion of
the Servicing Fee with respect to the related Due Period in an amount equal to
one-twelfth of the product of (a) the Servicing Fee Rate, (b) the Sellers'
Participation Amount as of the last day of the Due Period second preceding such
Distribution Date (or, if a Lump Addition occurs or a removal of Accounts
pursuant to Section 2.10 of the Agreement occurs in the following Due Period,
the weighted average of the Sellers' Participation Amount on the date on which
such Lump Addition or removal of Accounts occurs (after giving effect thereto)
and the last day of the second preceding Due Period) and (c) the Series 1998-3
Allocation Percentage for the related Due Period. In no event shall the Trust,
the Trustee, the Series 1998-3 Certificate-holders, the Cash Collateral
Depositor or any Additional Cash Collateral Depositor be liable for the share of
the Servicing Fee to be paid by the Sellers.

                  Section 4.02. Determination of Monthly Interest. (a) The
amount of monthly interest ("Class A Monthly Interest") distributable from the
Collection Account with respect to the Class A Certificates on any Distribution
Date shall be an amount equal to one-twelfth of the product of (i) the Class A
Certificate Rate and (ii) the outstanding principal balance of the Class A
Certificates as of the close of business on the preceding Distribution Date
(after giving effect to any distribution of Class A Monthly Principal on such
preceding Distribution Date), minus, for each Distribution Date with respect to
the Accumulation Period, the aggregate amount of all deposits of Class A Monthly
Principal previously made to the Class A Principal Funding Account; provided,
however, with respect to the first Distribution Date, Class A Monthly Interest
shall be equal to $805,555.56; and provided further, that with respect to the
first Distribution Date of the related Due Period in which an Additional
Issuance Date occurs, Class A Monthly Interest shall be increased by the amount
of interest accrued and payable at the Class A Certificate Rate on the principal
amount of Additional Class A Certificates through but excluding such
Distribution Date. Class A Monthly Interest shall be calculated on the basis of
a 360-day year of twelve 30-day months.

                  On the Determination Date preceding each Payment Date, the
Servicer shall determine the excess, if any (the "Class A Interest Shortfall")
of (x) the aggregate Class A Monthly Interest plus the aggregate Class A Covered
Amount for the Interest Period applicable to such Payment Date over (y) the
amount which will be on deposit in the Class A Interest Funding Account on such
Payment Date. If the Class A Interest Shortfall with respect to any Payment Date
is greater than zero, an additional amount ("Class A Additional Interest") equal
to one-twelfth of the product of (i) the Class A Certificate Rate and (ii) such
Class A Interest Shortfall (or the portion thereof which has not been paid to
Class A Certificateholders) shall be payable as provided herein with respect to
the Class A Certificates on each Distribution Date following such Payment Date
to and including the Payment Date on which such Class A Interest Shortfall is
paid to Class A Certificateholders. Notwithstanding anything to the contrary
herein, Class A Additional Interest shall be payable or distributed to Class A
Certificateholders only to the extent permitted by applicable law.

the product of (i) the Class B Certificate Rate and (ii) the Class B Invested
Amount as of the close of business on the preceding Distribution Date (after
giving effect to any increase or decrease of the Class B Invested Amount on such
preceding Distribution Date); provided, however, with respect to the first
Distribution Date, Class B Monthly Interest shall be equal to $52,888.89; and
provided further, that with respect to the first Distribution Date of the
related Due Period in which an Additional Issuance Date occurs, Class B Monthly
Interest shall be increased by the amount of interest accrued and payable at the
Class B Certificate Rate on the principal amount of Additional Class B
Certificates through but excluding such Distribution Date. Class B Monthly
Interest shall be calculated on the basis of a 360-day year of twelve 30-day
months.

                  On the Determination Date preceding each Payment Date, the
Servicer shall determine the excess, if any (the "Class B Interest Shortfall"),
of (x) the aggregate Class B Monthly Interest for the Interest Period applicable
to such Payment Date over (y) the amount which will be on deposit in the Class B
Interest Funding Account on such Payment Date. If the Class B Interest Shortfall
with respect to any Payment Date is greater than zero, an additional amount
("Class B Additional Interest") equal to one-twelfth of the product of (i) the
Class B Certificate Rate and (ii) such Class B Interest Shortfall (or the
portion thereof which has not been paid to Class B Certificateholders) shall be
payable as provided herein with respect to the Class B Certificates on each
Distribution Date following such Payment Date to and including the Payment Date
on which such Class B Interest Shortfall is paid to Class B Certificateholders.
Notwithstanding anything to the contrary herein, Class B Additional Interest
shall be payable or distributed to Class B Certificateholders only to the extent
permitted by applicable law.

                  Section 4.03. Determination of Monthly Principal. (a) The
amount of monthly principal ("Class A Monthly Principal") distributable from the
Collection Account with respect to the Class A Certificates on each Distribution
Date beginning with the first to occur of (i) the first Special Payment Date, if
any, and (ii) the first Distribution Date to occur with respect to the
Accumulation Period, shall be equal to the Available Investor Principal
Collections on deposit in the Collection Account with respect to such
Distribution Date; provided, however, that for each Distribution Date with
respect to any Monthly Period, Class A Monthly Principal shall not exceed the
Controlled Distribution Amount for such Distribution Date; and provided further
that Class A Monthly Principal shall not exceed the Class A Invested Amount.

                  (b) The amount of monthly principal ("Class B Monthly
Principal") distributable from the Collection Account with respect to the Class
B Certificates on each Distribution Date beginning with the Class B Principal
Commencement Date, shall be equal to the Available Investor Principal
Collections on deposit in the Collection Account with respect to such
Distribution Date (minus the portion of such Available Investor Principal
Collections applied to Class A Monthly Principal on such Distribution Date);
provided, however, that Class B Monthly Principal shall not exceed the Class B
Invested Amount.

                  Section 4.04. Establishment of Funding Accounts. (a) (i) The
Servicer, for the benefit of the Class A Certificateholders, shall establish and
maintain in the name of the Trustee, on behalf of the Trust, an Eligible Deposit

                  (ii) The Servicer, for the benefit of the Class B

                  (iii) Funds on deposit in the Interest Funding Accounts shall
be invested by the Servicer on behalf of the Trustee in Eligible Investments
selected by the Servicer. All such Eligible Investments shall be held by the
Trustee for the benefit of the Class A Certificateholders or the Class B
Certificateholders, as applicable; provided that on each Distribution Date, all
interest and other investment earnings (net of losses and investment expenses)
on funds on deposit in the Interest Funding Accounts shall be paid to the
Sellers. Funds deposited in the Interest Funding Accounts on any Distribution
Date (which are not distributed to Class A Certificateholders or Class B
Certificateholders, as applicable, pursuant to Section 4.07 on such Distribution
Date) shall be invested in Eligible Investments that will mature so that such
funds will be available at the close of business on the Transfer Date preceding
the following Distribution Date. Funds deposited in either Interest Funding
Account on a Transfer Date (which immediately precedes a Payment Date) upon the
maturity of any Eligible Investments are not required to be invested overnight.

                  (b) (i) The Servicer, for the benefit of the Class A
Certificateholders, shall establish and maintain in the name of the Trustee, on
behalf of the Trust, an Eligible Deposit Account (the "Class A Principal Funding

therein are held for the benefit of the Class A Certificateholders. The Class A
Principal Funding Account shall initially be established with Citibank, N.A.

                  (ii) Funds on deposit in the Class A Principal Funding Account
shall be invested by the Servicer on behalf of the Trustee in Eligible
Investments selected by the Servicer. All such Eligible Investments shall be
held by the Trustee for the benefit of the Class A Certificateholders; provided
that on each Distribution Date all interest and other investment income (net of
investment expenses) on funds on deposit therein shall be applied as set forth
in clause (iii) below. Funds on deposit in the Class A Principal Funding Account
shall be invested in Eligible Investments that will mature so that such funds
will be available at the close of business on the Transfer Date preceding the
following Distribution Date. Funds deposited in the Class A Principal Funding
Account on a Transfer Date (which immediately precedes a Payment Date) upon the
maturity of any Eligible Investments are not required to be invested overnight.

                  (iii) On each Distribution Date with respect to the
Accumulation Period, the Servicer shall withdraw from the Class A Principal
Funding Account and deposit in the Class A Interest Funding Account all interest
and other investment income (net of investment expenses) on funds then on
deposit in the Class A Principal Funding Account; provided, however, that Class
A Excess Investment Proceeds, if any, with respect to any Distribution Date,
shall be deposited in the Collection Account and treated as a portion of the
Gross Amount.

                  (iv) Reinvested interest and other investment income on funds
deposited in the Class A Principal Funding Account shall not be considered to be
principal amounts on deposit therein for purposes of this Series Supplement.

be under the sole dominion and control of the Trustee for the benefit of the
Class A Certificateholders, Class B Certificateholders, the Cash Collateral
Depositor or any Additional Cash Collateral Depositor, as the case may be. If,
at any time, any of the Series 1998-3 Accounts ceases to be an Eligible Deposit
Account, the Trustee (or the Servicer on its behalf) shall within 10 Business
Days (or such longer period, not to exceed 30 calendar days, as to which each
Rating Agency may consent) establish a new Series 1998-3 Account meeting the
conditions specified in paragraph (a)(i) or (ii) or (b)(i) above, as applicable,
as an Eligible Deposit Account and shall transfer any cash and/or any
investments to such new Series 1998-3 Account.

(i) Class A Monthly Interest for such Distribution Date, (ii) any Class A
Monthly Interest previously due but not deposited in the Class A Interest
Funding Account on a prior Distribution Date, (iii) Class A Additional Interest,
if any, for such Distribution Date and any Class A Additional Interest
previously due but not deposited into the Class A Interest Funding Account on a
prior Distribution Date (but not including any amount relating to any Class A

                  Section 4.08. Investor Charge-Offs. (a) If on any Distribution
Date the Required Amount for such Distribution Date exceeds the sum of (x) the
amount of Subordinated Principal Collections with respect to such Distribution
Date, (y) the amount of Excess Finance Charge Collections with respect to such
Distribution Date and (z) the Available Shared Enhancement Amount with respect
to such Distribution Date, the CCA Invested Amount shall be reduced by the
amount of such excess, but not by more than the Class A Investor Default Amount
for such Distribution Date. In the event that such reduction would cause the CCA
Invested Amount to be a negative number, the CCA Invested Amount shall be
reduced to zero, and the Class B Invested Amount shall be reduced by the amount
by which the CCA Invested Amount would have been reduced below zero, but not by
more than the excess, if any, of the Class A Investor Default Amount for such
Distribution Date over the amount of such reduction, if any, of the CCA Invested
Amount. In the event that such reduction would cause the Class B Invested Amount
to be a negative number, the Class B Invested Amount shall be reduced to zero,
and the Class A Invested Amount will be reduced by the amount by which the Class
B Invested Amount would have been reduced below zero, but not by more than the
excess, if any, of the Class A Investor Default Amount for such Distribution
Date over the aggregate amount of the reductions, if any, of the CCA Invested
Amount and the Class B Invested Amount for such Distribution Date pursuant to
this Section 4.08(a) (a "Class A Investor Charge-Off"). Class A Investor
Charge-Offs shall thereafter be reimbursed and the Class A Invested Amount
increased (but not by an amount in excess of the aggregate Class A Investor
Charge-Offs) on any Distribution Date by the sum of (i) Allocable Miscellaneous
Payments with respect to such Distribution Date and (ii) the amount of Excess
Finance Charge Collections allocated and available for that purpose pursuant to
Section 4.09(b).

                  (b) If on any Distribution Date the Class B Investor Default
Amount for such Distribution Date exceeds the sum of (x) the amount of Excess
Finance Charge Collections with respect to such Distribution Date which are
allocated and available to pay the Class B Investor Default Amount pursuant to
Section 4.09(d) and (y) the portion, if any, of the Available Shared Enhancement
Amount with respect to such Distribution Date (after giving effect to any
withdrawal from the Cash Collateral Account or any Additional Cash Collateral
Account to fund the Required Draw Amount with respect to such Distribution
Date), then the CCA Invested Amount shall be reduced by the amount of such
excess. In the event that such reduction would cause the CCA Invested Amount to
be a negative number, the CCA Invested Amount shall be reduced to zero, and the
Class B Invested Amount shall be reduced by the amount by which the CCA Invested
Amount would have been reduced below zero (a "Class B Investor Charge-Off").
Class B Investor Charge-Offs shall thereafter be reimbursed and the Class B
Invested Amount increased (but not by an amount in excess of the aggregate Class
B Investor Charge-Offs) on any Distribution Date by the sum of (i) Allocable
Miscellaneous Payments with respect to such Distribution Date (but only to the
extent such amount is not required to reimburse Class A Investor Charge-Offs
pursuant to paragraph (a) above) and (ii) the amount of Excess Finance Charge
Collections allocated and available for that purpose pursuant to Section
4.09(f).

                  (c) If on any Distribution Date Subordinated Principal
Collections for such Distribution Date are allocated pursuant to Section
4.10(a), the CCA Invested Amount shall be reduced by the amount of such
Subordinated Principal Collections. In the event that such reduction would cause
the CCA Invested Amount to be a negative number, the CCA Invested Amount shall
be reduced to zero, and the Class B Invested Amount shall be reduced by the
amount by which the CCA Invested Amount would have been reduced below zero.

                  (d) If on any Distribution Date the CCA Default Amount for
such Distribution Date exceeds the amount of Excess Finance Charge Collections
with respect to such Distribution Date which are allocated and available to pay
the CCA Default Amount pursuant to Section 4.09(h), then the CCA Invested Amount
shall be reduced by the amount of such excess (a "CCA Charge-Off"). CCA
Charge-Offs shall thereafter be reimbursed and the CCA Invested Amount increased
(but not by an amount in excess of the aggregate CCA Charge-Offs) on any
Distribution Date by the sum of (i) Allocable Miscellaneous Payments with
respect to such Distribution Date (but only to the extent such amount is not
required to reimburse Class A Investor Charge-Offs or Class B Investor
Charge-Offs pursuant to paragraph (a) or (b) above) and (ii) the amount of
Excess Finance Charge Collections allocated and available for that purpose
pursuant to Section 4.09(i).

to apply, on each Distribution Date (or on the related Transfer Date, if so
specified), Excess Finance Charge Collections with respect to such Distribution
Date, to make the following distributions in the following priority:

                  (a) an amount equal to the Required Amount, if any, with

         including any amount relating to any Class A Funding Account Shortfall)
         and second to pay the Class A Investor Default Amount, if any, for such
         Distribution Date pursuant to Section 4.06(a)(ii) or (c)(ii), as the
         case may be; provided, however, that at such time as Citibank (South
         Dakota) or an Affiliate of Citibank (South Dakota) is no longer the
         Servicer, such Excess Finance Charge Collections shall be distributed
         second to fund any deficiency in the Class A Monthly Servicing Fee for
         such Distribution Date and third to pay the Class A Investor Default
         Amount, if any, for such Distribution Date;

         portion of Investor Principal Collections with respect to such
         Distribution Date;

                  (c) an amount equal to (i) Class B Monthly Interest due but
         not deposited into the Class B Interest Funding Account on such
         Distribution Date, plus the amount of any Class B Monthly Interest
         previously due but not deposited into the Class B Interest Funding
         Account on a prior Distribution Date, (ii) the Cumulative Excess
         Interest Amount for such Distribution Date and (iii) the amount of any

         Interest Funding Account on such Distribution Date and any Class B
         Additional Interest previously due but not deposited into the Class B
         Interest Funding Account on a prior Distribution Date, shall be
         deposited into the Class B Interest Funding Account;

                  (d) an amount equal to the Class B Investor Default Amount for
         such Distribution Date shall be treated as a portion of Investor
         Principal Collections with respect to such Distribution Date;

         Date has occurred, an amount equal to the CCA Monthly Servicing Fee for

         occurrence of an Economic Amortization Event, an amount equal to the
         lesser of (i) the balance of such Excess Finance Charge Collections and
         (ii) the sum of (A) the excess, if any, of the Initial Cash Collateral
         Amount over the amount of funds on deposit in the Cash Collateral

         Available Shared Enhancement Amount for such Distribution Date and the
         amount of Excess Finance Charge Collections and Subordinated Principal

         any, for such Distribution Date pursuant to Section 4.06(a)(ii) or

                  Section 4.11. Credit Enhancement. (a) The Servicer shall
establish and maintain, in the name of the Trustee, on behalf of the Trust, for
the benefit of the Series 1998-3 Certificateholders and the Cash Collateral
Depositor, as their interests appear herein, a "Sellers Collateral Account" and
a "Bank Collateral Account", each of which shall be one or more Eligible Deposit
Accounts, each bearing a designation clearly indicating that the funds deposited
therein are held for the benefit of the Series 1998-3 Certificateholders and the
Cash Collateral Depositor. The Sellers Collateral Account and the Bank

on deposit from time to time in the Cash Collateral Account and in all proceeds

                  (a.1) On each Additional Issuance Date, the Servicer shall
establish and maintain, in the name of the Trustee, on behalf of the Trust, for
the benefit of the Series 1998-3 Certificateholders and the related Additional
Cash Collateral Depositor, as their interests appear in this Series Supplement,
an "Additional Cash Collateral Account" which shall be one or more Eligible

Agreement. If at any time any of the accounts comprising the Additional Cash

Deposit Account, and shall transfer any cash and/or any investments to such new

                  (b) Funds on deposit in the Cash Collateral Account shall be
invested at the direction of the Servicer (or the Cash Collateral Depositor, as
provided in the Loan Agreement) by the Trustee in Cash Collateral Account
Investments. Funds on deposit in the Cash Collateral Account on any Transfer
Date, after giving effect to any withdrawals from the Cash Collateral Account on

that such funds will be available for withdrawal on or prior to the following
Transfer Date. The proceeds of any such investments shall be invested in such
investments that will mature so that such funds will be available for withdrawal
on or prior to the Transfer Date immediately following the date of such
investment. The Trustee shall maintain for the benefit of the Series 1998-3
Certificateholders and the Cash Collateral Depositor possession of the
negotiable instruments or securities, if any, evidencing the Cash Collateral
Account Investments. On each Transfer Date, all interest and earnings (net of
losses and investment expenses) accrued since the preceding Transfer Date on
funds on deposit in the Cash Collateral Account shall be paid to the Cash
Collateral Depositor for application in accordance with the Loan Agreement. For
purposes of determining the availability of funds or the balances in the Cash
Collateral Account for any reason under this Series Supplement, all investment
earnings on such funds shall be deemed not to be available or on deposit.

                  (b.1) Funds on deposit in each Additional Cash Collateral
Account shall be invested at the direction of the Servicer (or the related
Additional Cash Collateral Depositor, as provided in the related Additional Loan
Agreement) by the Trustee in Cash Collateral Account Investments. Funds on
deposit in each Additional Cash Collateral Account on any Transfer Date, after
giving effect to any withdrawals from such Additional Cash Collateral Account on
such Transfer Date, shall be invested in such investments that will mature so
that such funds will be available for withdrawal on or prior to the following
Transfer Date. The proceeds of any such investments shall be invested in such
investments that will mature so that such funds will be available for withdrawal
on or prior to the Transfer Date immediately following the date of such

Transfer Date, all interest and earnings (net of losses and investment expenses)
accrued since the preceding Transfer Date on funds on deposit in each Additional
Cash Collateral Account shall be paid to the related Additional Cash Collateral

Supplement, all investment earnings on such funds shall be deemed not to be
available or on deposit.

                  (c) On each Determination Date, the Servicer shall calculate
the amount (the "Required Draw Amount") (determined after giving effect to any
distribution to be made pursuant to Section 4.06(a)(i) or (c)(i), as the case
may be, and Section 4.06(a)(ii) or (c)(ii), as the case may be, on the related
Distribution Date) equal to the excess, if any, of (i) the Required Amount, if
any, with respect to such Distribution Date over (ii) the amount of Excess
Finance Charge Collections to be allocated and available pursuant to Section
4.09(a) to fund such Required Amount on such Distribution Date.

                  (d) On each Determination Date, the Servicer shall calculate
the amount (the "Interest Draw Amount") (determined after giving effect to any
distribution to be made pursuant to Section 4.06(b)(i) or (d)(i), as the case
may be, and Section 4.09(c) on the related Distribution Date) of (i) any Class B
Monthly Interest due but not to be deposited into the Class B Interest Funding
Account on such Distribution Date pursuant to Section 4.06(b)(i) or (d)(i), as
the case may be, or Section 4.09(c), (ii) any Class B Monthly Interest
previously due but not deposited into the Class B Interest Funding Account on a
prior Distribution Date pursuant to Section 4.06(b)(i) or (d)(i), as the case
may be, or Section 4.09(c) or this paragraph (d), (iii) any Class B Additional
Interest due but not to be deposited into the Class B Interest Funding Account
on such Distribution Date and any Class B Additional Interest previously due but
not deposited into the Class B Interest Funding Account on a prior Distribution
Date pursuant to Section 4.06(b)(i) or (d)(i), as the case may be, or Section

                  (e) On each Determination Date, the Servicer shall calculate
the amount (the "Default Draw Amount") equal to the excess, if any, of (i) the
Class B Investor Default Amount for the related Distribution Date over (ii) the
amount of Excess Finance Charge Collections to be allocated and available
pursuant to Section 4.09(d) to fund such Class B Investor Default Amount on such
Distribution Date.

                  (f) On each Determination Date (commencing with the
Determination Date preceding the Class B Principal Commencement Date), the
Servicer shall calculate the amount (the "Reimbursement Draw Amount") equal to
the excess, if any, of (i) the Class B Initial Invested Amount minus the sum of
the aggregate amount of principal payments previously distributed to Class B
Certificateholders over (ii) the Class B Invested Amount on the last day of the
related Due Period (determined after giving effect to any change to be made in
the Class B Invested Amount pursuant to paragraph (c), (d), (e) or (f) of the
definition of "Class B Invested Amount" on the following Distribution Date).

                  (g) Notwithstanding Section 4.11(f), if either (i) the
Certificateholders' Interest in the Receivables is reassigned to the Sellers
pursuant to Section 2.06 of the Agreement, (ii) Receivables are sold, disposed
of or otherwise liquidated pursuant to Section 9.02 or Section 12.02(c) of the
Agreement or (iii) the Certificateholders' Interest in the Receivables is
purchased by the Sellers pursuant to Section 10.01 of the Agreement or the
Series 1998-3 Certificateholders' Interest is purchased by the Sellers pursuant
to Section 7.01 of this Series Supplement, the Servicer shall not calculate the
Reimbursement Draw Amount with respect to the relevant Distribution Date, but
shall calculate the amount (the "Special Draw Amount") equal to the aggregate
amount of all reductions of the Class B Invested Amount occurring under clauses
(c), (d) or (e) of the definition of "Class B Invested Amount" which have not
been reimbursed prior to such Distribution Date under clause (f) thereof.

                  (h) Notwithstanding Section 4.11(f) and (g), on the
Determination Date preceding the Economic Special Payment Date, the Servicer
shall not calculate the Reimbursement Draw Amount or the Special Draw Amount
with respect to such Special Payment Date, but shall calculate (i) the amount
(the "Class A Principal Draw Amount") (determined after giving effect to any
distribution to be made pursuant to Section 4.06(f)(i) and 4.07(a)(ii) on such
Special Payment Date) equal to the outstanding principal amount of the Class A
Certificates and (ii) the amount (the "Class B Principal Draw Amount")
(determined after giving effect to any distribution to be made pursuant to
Section 4.06(f)(iii) and 4.07(b)(ii) on such Special Payment Date) equal to the
outstanding principal amount of the Class B Certificates.

                  (i) In the event that for any Distribution Date, the sum of
any Required Draw Amount, Interest Draw Amount, Default Draw Amount,
Reimbursement Draw Amount, Special Draw Amount, Class A Principal Draw Amount
and Class B Principal Draw Amount (such sum being referred to as the "Total Draw
Amount"), is greater than zero, the Servicer shall give written notice to the
Trustee, the Cash Collateral Depositor and each Additional Cash Collateral
Depositor, in substantially the form of Exhibits B-1 and B-2, respectively, of
such positive Total Draw Amount on the related Determination Date. On the
related Transfer Date, withdrawals will be made from the Cash Collateral Account
and each Additional Cash Collateral Account as follows:

                  (A) the portion of the Total Draw Amount allocable to the
         Required Draw Amount, if any, up to the Available Shared Enhancement
         Amount, shall be withdrawn, pro rata, from the Cash Collateral Account
         and each Additional Cash Collateral Account, in each case, on the
         related Transfer Date and distributed first to fund any deficiency
         pursuant to Section 4.06(a)(i) or (c)(i) (but not including any amount
         relating to any Class A Funding Account Shortfall) and second to pay
         the Class A Investor Default Amount, if any, for such Distribution Date
         pursuant to Section 4.06(a)(ii) or (c)(ii), as the case may be;
         provided, however, that at such time as Citibank (South Dakota) or an
         Affiliate of Citibank (South Dakota) is no longer the Servicer, the
         amount of such withdrawal from the Cash Collateral Account and each
         Additional Cash Collateral Account shall be applied in accordance with
         Section 4.10(a) second to fund any deficiency in the Class A Monthly
         Servicing Fee for such Distribution Date and third to pay the Class A
         Investor Default Amount, if any, for such Distribution Date;

                  (B) the portion of the Total Draw Amount allocable to the
         Interest Draw Amount, if any, up to the Available Shared Enhancement
         Amount (determined after giving effect to any withdrawal pursuant to
         clause (A)), shall be withdrawn, pro rata, from the Cash Collateral
         Account and each Additional Cash Collateral Account, in each case, on
         the related Transfer Date and immediately deposited by the Trustee into
         the Class B Interest Funding Account;

                                                                              52


                  (C) the portion of the Total Draw Amount allocable to the
         Default Draw Amount, if any, up to the Available Shared Enhancement
         Amount (determined after giving effect to any withdrawal pursuant to
         clauses (A) and (B)), shall be withdrawn, pro rata, from the Cash
         Collateral Account and each Additional Cash Collateral Account, in each
         case, on the related Transfer Date and used to pay the Class B Investor
         Default Amount for such Distribution Date pursuant to Section 4.09(d);

                  (D) the portion of the Total Draw Amount allocable to the
         Class A Principal Draw Amount, if any, up to the Available Shared
         Enhancement Amount (determined after giving effect to any withdrawal
         pursuant to clauses (A), (B) and (C)), shall be withdrawn, pro rata,
         from the Cash Collateral Account and each Additional Cash Collateral
         Account, in each case, on the related Transfer Date and immediately
         deposited by the Trustee into the Class A Principal Funding Account;
         and

                  (E) the remainder of the Total Draw Amount, if any, up to the
         Available Enhancement Amount (determined after giving effect to any
         withdrawal pursuant to clauses (A) through (D)), shall be withdrawn,
         pro rata, from the Cash Collateral Account and each Additional Cash
         Collateral Account, in each case, on the related Transfer Date and
         immediately deposited by the Trustee into the Collection Account for
         distribution to the Class B Certificateholders on such Distribution
         Date.

Notwithstanding anything to the contrary in this Series Supplement or in the
Agreement, no withdrawal may be made from the Cash Collateral Account or any
Additional Cash Collateral Account to fund any Class A Funding Account
Shortfall. For the avoidance of doubt, after any Additional Issuance Date, no
withdrawal shall be made from the Cash Collateral Account or any Additional Cash
Collateral Account on any basis other than pro rata and no withdrawal shall be
made from the Cash Collateral Account or any Additional Cash Collateral Account
to fund any amount which is required to be withdrawn pursuant to this Series
Supplement from any other cash collateral account.

accordance with the instructions of the Servicer, after the prior payment of all
amounts owing to the Class A Certificateholders and the Class B
Certificateholders which are payable from the Cash Collateral Account and each
Additional Cash Collateral Account as provided herein, shall withdraw from the

application in accordance with the Loan Agreement and the related Additional
Loan Agreements, respectively all amounts, if any, on deposit in the Cash

         Collections less the sum of (i) Group One Investor Monthly Interest,

Collections for such Distribution Date exceeds the sum of (i) Group One Investor
Monthly Interest, (ii) Group One Investor Default Amount, (iii) Group One
Investor Monthly Fees and (iv) Group One Investor Additional Amounts, then
Reallocated Investor Finance Charge Collections for such Distribution Date shall
include an amount equal to the product of (x) the amount of such excess and (y)
a fraction, the numerator of which is the Invested Amount as of the last day of
the second preceding Due Period and the denominator of which is the sum of such
Invested Amount and the aggregate invested amounts for all other Series included
in Group One as of such last day.

of Excess Principal Collections for any Distribution Date equal to the amount of
Series 1998-3 Excess Principal Collections for such Distribution Date will be

Supplement.

                  (b) Series 1998-3 Excess Principal Collections, for any
Distribution Date with respect to the Accumulation Period or the Early
Amortization Period, shall mean an amount equal to the Series 1998-3 Principal
Shortfall for such Distribution Date; provided, however, that if the aggregate
amount of Excess Principal Collections for all Series for such Distribution Date
is less than the aggregate amount of Principal Shortfalls for all Series for
such Distribution Date, then Series 1998-3 Excess Principal

Date occurring on or after the date on which the Invested Amount is reduced to
5% of the Initial Invested Amount or less, the Sellers shall have the option to
purchase the Series 1998-3 Certificateholders' Interest, at a purchase price
equal to the Reassignment Amount for such Distribution Date.

                  (b) The Sellers shall give the Servicer and the Trustee at
least 30 days prior written notice of the date on which the Sellers intend to
exercise such purchase option. Not later than 12:00 noon, New York City time, on
such Distribution Date the Sellers shall deposit the Reassignment Amount into
the Collection Account in immediately available funds. Such purchase option is
subject to payment in full of the Reassignment Amount. The Reassignment Amount
shall be distributed as set forth in Section 8.01(b).

                  (c) If the Loan Agreement or any Additional Loan Agreement so
provides, in the event the Sellers exercise such purchase option,
notwithstanding anything to the contrary contained in the Agreement or in this
Series Supplement, the Series 1998-3 Certificates shall be deemed to remain
outstanding as if such purchase option were not exercised and the terms of the
Agreement and this Series Supplement (other than Section 4.11(c) through (i) of
this Series Supplement and Section 12.02(c) of the Agreement) shall otherwise
remain in effect until the earlier of (i) one year and one day following the
Termination Date, (ii) the date on which the Trust terminates and (iii) the date
on which the Class A Invested Amount, the Class B Invested Amount and the CCA
Invested Amount, if any, would have been paid in full had such purchase option
not been exercised; provided that distributions which would otherwise have been
made to the Series 1998-3 Certificateholders shall be made to the Sellers.

                  (v) the Sellers shall have delivered to the Trustee, each

         laws and (C) such other documents as the Rating Agencies may request;

                  (vii) the Rating Agency Condition shall have been satisfied
         with respect to such Additional Issuance;

                  (viii) such Additional Issuance shall not have an Adverse
         Effect and is not reasonably expected to have an Adverse Effect at any
         time in the future;

                  (ix) as of the Additional Issuance Date all amounts due and
         owing to the Series 1998-3 Certificateholders on or prior to such date
         shall have been paid to such Certificateholders and there shall not be
         any unreimbursed Investor Charge-Offs;

         Internal Revenue Code without the creation of original issue discount
         (assuming that there is no original issue discount on the Additional
         Investor Certificates for any other reason);

                  (xi) the Banks' Interest shall not be less than 2% of the
         total amount of Principal Receivables, in each case as of the

                  (xiii) the Sellers shall cause additional credit enhancement
         to be provided by the Cash Collateral Depositor or any additional
         Series Enhancer for the exclusive benefit of the Investor
         Certificateholders; provided that the ratio of the Available
         Enhancement Amount (after giving effect to such increase) to the
         Invested Amount (after giving effect to such Additional Issuance) shall
         be greater than or equal to the ratio of the Available Enhancement
         Amount (before giving effect to such increase) to the Invested Amount
         (before giving effect to such Additional Issuance);

                  (xiv) the ratio of the sum of the increase in the Class A

         the Class A Investment Fees as of the Closing Date is less than
         $10,000, the sum of the increase in the Class A Investment Fees (as a
         result of such Additional Issuance) shall be less than $100,000; and

                  (xv) the Sellers shall have delivered to the Trustee an
         Officer's Certificate, dated the Additional Issuance Date, confirming

Series Supplement, this Series Supplement may be amended by the Servicer, the

                  Section 7.03. Accumulation Period Postponement. The
Accumulation Period is scheduled to commence at the close of business on the
fourth-to-last Business Day of January 2002; provided, however, that if the
Accumulation Period Length (determined as described below) is less than twelve
months, upon notice to the Trustee, the Sellers, the Rating Agency and the Cash
Collateral Depositor, the Servicer, at its option, may elect to postpone the
date on which the Accumulation Period actually commences to the fourth-to-last
Business Day of any month that precedes the month that is the number of months
prior to the Class A Expected Final Payment Date, equal to the Accumulation
Period Length such that the number of Monthly Periods in the Accumulation Period
will equal or exceed the Accumulation Period Length. On the Determination Date
immediately preceding the January 2002 Distribution Date, the Servicer will
determine the "Accumulation Period Length" which will equal the number of months
such that the sum of the Accumulation Period Amounts for each Monthly Period,
beginning with (and assigning the largest Accumulation Period Amount to) the
Monthly Period that ends on the day preceding the Class A Expected Final Payment
Date, when aggregated with the Accumulation Period Amounts for each preceding
Monthly Period will equal or exceed the Initial Invested Amount. If the Servicer
elects to postpone the commencement of the Accumulation Period pursuant to this
Section 7.03, then on each Determination Date thereafter until the date the
Accumulation Period commences, the Servicer will recalculate the Accumulation
Period Length; provided, however, that (i) the length of the Accumulation Period
shall not be shorter than the period determined as of the first date of
determination unless an additional Series, other than an Excluded Series, shall
have been issued since such date and such Series is in its revolving period;
(ii) the length of the Accumulation Period will not be less than one month; and
(iii) no election to postpone, or further postpone, the commencement of the
Accumulation Period shall be made after an economic amortization event (as
defined in the related Supplement) shall have occurred and is continuing with
respect to any other Series. If the Accumulation Period Length as recalculated
on any such Determination Date exceeds the number of Monthly Periods then
scheduled to be included in the Accumulation Period, the commencement date of
the Accumulation Period will be changed to the later of (x) such Determination
Date and (y) the fourth-to-last Business Day of a month such that the number of
Monthly Periods in the Accumulation Period will equal the recalculated
Accumulation Period Length. Any notice by the Servicer electing to postpone (or
further postpone) the commencement of the Accumulation Period pursuant to this
Section 7.03 shall specify (i) the Accumulation Period Length, (ii) the
commencement date of the Accumulation Period and (iii) the Controlled
Amortization Amount with respect to each Monthly Period.

quoted on the Record Date preceding the date of repurchase or, if not a Business

remaining maturity of the Class A Certificates and rated by each Rating Agency
in the rating category originally assigned to the Class A Certificates over (II)
the portion of the Reassignment Amount attributable to the Class A Certificates
and (B) the excess, if any, of (I) a price equivalent to the average of bids

This certifies that [ ] (the "Class A Certificateholder") is the registered
owner of a fractional undivided interest in certain assets of a trust (the
"Trust") created pursuant to the Pooling and Servicing Agreement dated as of May
29, 1991 (as amended and supplemented, the "Agreement"), as supplemented by the
Series 1998-3 Supplement dated as of January 29, 1998 (as amended and
supplemented, the "Series Supplement"), among Citibank (South Dakota), N.A., a
national banking association, as Seller and Servicer, Citibank (Nevada),
National Association, a national banking association, as Seller, and Bankers
Trust Company, a New York banking corporation, as successor to Yasuda Bank and
Trust Company (U.S.A.), as trustee (the "Trustee"). The corpus of the Trust
consists of (i) a portfolio of all receivables (the "Receivables") existing in
the revolving credit card accounts identified under the Agreement from time to
time (the "Accounts"), (ii) all Receivables generated under the Accounts from
time to time thereafter, (iii) funds collected or to be collected from
cardholders in respect of the Receivables, (iv) all funds which are from time to
time on deposit in the Collection Account and in the Series Accounts, (v) the
benefits of the Cash Collateral Account and (vi) all other assets and interests
constituting the Trust. The Holder of this Certificate is entitled to the
benefit of funds on deposit in a Cash Collateral Account to the extent provided
in the Series Supplement. Although a summary of certain provisions of the
Agreement and the Series Supplement is set forth below and on the Summary of
Terms and Conditions attached hereto and made a part hereof, this Class A
Certificate does not purport to summarize the Agreement and the Series
Supplement and reference is made to the Agreement and the Series Supplement for
information with respect to the interests, rights, benefits, obligations,
proceeds and duties evidenced hereby and the rights, duties and obligations of
the Trustee. A copy of the Agreement and the Series Supplement (without
schedules) may be requested from the Trustee by writing to the Trustee at the
Corporate Trust Office. To the extent not defined herein, the capitalized terms
used herein have the meanings ascribed to them in the Agreement or the Series
Supplement, as applicable.

                  This Class A Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement and the Series Supplement, to
which Agreement and Series Supplement, each as amended and supplemented from
time to time, the Class A Certificateholder by virtue of the acceptance hereof
assents and is bound.

                  It is the intent of the Sellers and the Investor
Certificateholders that, for Federal, state and local income and franchise tax
purposes only, the Investor Certificates will qualify as indebtedness of the
Sellers secured by the Receivables. The Class A Certificateholder, by the
acceptance of this Class A Certificate, agrees to treat this Class A Certificate
for Federal, state and local income and franchise tax purposes as indebtedness
of the Sellers.

                  In general, payments of principal with respect to the Class A
Certificates are limited to the Class A Invested Amount, which may be less than
the unpaid principal balance of the Class A Certificates. The Class A Expected
Final Payment Date is the February 2003 Distribution Date, but principal with
respect to the Class A Certificates may be paid earlier or later under certain
circumstances described in the Agreement and the Series Supplement. If for one
or more months during the Accumulation Period there are not sufficient funds to
pay the Controlled Amortization Amount, then to the extent that excess funds are
not available on subsequent Distribution Dates with respect to the Accumulation
Period to make up for such shortfalls, the final payment of principal of the
Class A Certificates will occur later than the Class A Expected Final Payment
Date. If the principal of the Class A Certificates and the Class B Certificates
is not paid in full on or prior to the Termination Date, the Trustee will sell
or cause to be sold on such Termination Date Principal Receivables (and the
related Finance Charge Receivables) (or interests therein) in an amount equal to
110% of the Invested Amount as of such Termination Date, subject to certain
limitations, and shall immediately deposit the Termination Proceeds allocable to
the Series 1998-3 Certificateholders' Interest in the Collection Account. The
Termination Proceeds shall be allocated and distributed to the Class A
Certificateholders and the Class B Certificateholders in accordance with the
Series Supplement.

               5.80% CLASS A CREDIT CARD PARTICIPATION CERTIFICATE

                         Summary of Terms and Conditions


The Receivables consist of Principal Receivables which arise generally from the
purchase of merchandise and services and amounts advanced to cardholders as cash
advances and Finance Charge Receivables which arise generally from Periodic Rate
Finance Charges, Cash Advance Fees, Late Payment Fees and annual membership fees
with respect to the Accounts. This Class A Certificate is one of a series of

"Series 1998-3 Certificates"), and one of a class thereof entitled 5.80% Class A
Credit Card Participation Certificates, Series 1998-3 (the "Class A
Certificates"), each of which represents a fractional undivided interest in
certain assets of the Trust. The Trust Assets are allocated in part to the
certificateholders of all outstanding Series (the "Certificateholders'
Interest") with the remainder allocated to the Sellers. The aggregate interest
represented by the Class A Certificates at any time in the Principal Receivables
in the Trust shall not exceed an amount equal to the Class A Invested Amount at
such time. The Class A Initial Invested Amount is $625,000,000. The Class A
Invested Amount on any date will be an amount equal to (a) the Class A Initial
Invested Amount, minus (b) the aggregate amount of principal payments made to
Class A Certificateholders prior to such date, minus (c) the Class A Principal
Funding Account Balance as of such date and minus (d) the excess, if any, of the
aggregate amount of Class A Investor Charge-Offs over Class A Investor
Charge-Offs reimbursed pursuant to Section 4.08 of the Series Supplement prior
to such date. In addition to the Class A Certificates, a class of the Series
1998-3 Certificates entitled 5.95% Class B Credit Card Participation
Certificates, Series 1998-3 (the "Class B Certificates") will be issued. Also, a
Sellers' Certificate has been issued to the Sellers pursuant to the Agreement
which represents the Sellers' Interest.

Subject to the terms and conditions of the Agreement, the Sellers may from time
to time direct the Trustee, on behalf of the Trust, to issue one or more new
Series of Investor Certificates, which will represent fractional undivided
interests in certain of the Trust Assets.

On each Payment Date, the Paying Agent shall distribute to each Class A
Certificateholder of record on the last day of the preceding calendar month
(each a "Record Date") such Class A Certificateholder's pro rata share of such
amounts on deposit in the Class A Interest Funding Account or the Class A
Principal Funding Account as are payable to the Class A Certificateholders
pursuant to the Agreement and the Series Supplement. Distributions with respect
to this Class A Certificate will be made by the Paying Agent by check mailed to
the address of the Class A Certificateholder of record appearing in the
Certificate Register without the presentation or surrender of this Class A
Certificate or the making of any notation thereon (except for the final
distribution in respect of this Class A Certificate) except that with respect to
Class A Certificates registered in the name of Cede & Co., the nominee for The
Depository Trust Company, distributions will be made in the form of immediately
available funds. Final payment of this Class A Certificate will be made only
upon presentation and surrender of this Class A Certificate at the office or

the Class A Certificateholders in accordance with the Agreement and the Series
Supplement.

On the Distribution Date occurring on or after the date on which the Invested
Amount is reduced to 5% of the Initial Invested Amount or less, the Sellers have
the option to repurchase the Series 1998-3 Certificateholders' Interest in the
Trust. The repurchase price (determined after giving effect to any payment of
principal and interest on such Distribution Date) will be equal to the
Reassignment Amount for such Distribution Date.

This Class A Certificate does not represent an obligation of, or an interest in,
the Sellers, the Servicer or any affiliate of any of them and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other
governmental agency or instrumentality. This Class A Certificate is limited in

certain other amounts), all as more specifically set forth hereinabove and in
the Agreement and the Series Supplement.

The Agreement or any Supplement may, subject to certain conditions, be amended
by the Sellers, the Servicer and the Trustee without Investor Certificateholder

Certificates evidencing not less than 66-2/3% of the aggregate unpaid principal
amount of the Investor Certificates of all adversely affected Series, for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of the Agreement or any Supplement or of modifying in any
manner the rights of the Investor Certificateholders; provided, however, that no
such amendment shall (i) reduce in any manner the amount of or delay the timing
of any distributions to be made to Investor Certificateholders or deposits of
           amounts to be so distributed or the amount available under any Series
Enhancement without the consent of each affected Investor Certificateholder,

Investor Certificateholder without the consent of each affected Investor
Certificateholder, (iii) reduce the aforesaid percentage required to consent to

without the consent of the Holders of Investor Certificates of such Series or
Class evidencing not less than 66-2/3% of the aggregate unpaid principal amount
of the Investor Certificates of such Series or Class. The Trustee may, but shall
not be obligated to, enter into any such amendment which affects the Trustee's
rights, duties or immunities under this Agreement or otherwise.

The Class A Certificates are issuable only in minimum denominations of $1,000
and integral multiples of $1,000. The transfer of this Class A Certificate shall
be registered in the Certificate Register upon surrender of this Class A
Certificate for registration of transfer at any office or agency maintained by
the Transfer Agent and Registrar accompanied by a written instrument of
transfer, in a form satisfactory to the Trustee or the Transfer Agent and
Registrar, duly executed by the Class A Certificateholder or such Class A
Certificateholder's attorney, and duly authorized in writing with such signature

As provided in the Series Supplement, the Banks may, from time to time, during
the Revolving Period, subject to certain conditions set forth in the Series
Supplement, cause the Trustee to issue Additional Class A Certificates. When
issued, the Additional Class A Certificates will be identical in all respects to

entitled to the benefits of the Agreement and the Series Supplement without
preference, priority or distinction.

As provided in the Agreement and subject to certain limitations therein set
forth, Class A Certificates are exchangeable for new Class A Certificates
evidencing like aggregate fractional undivided interests as requested by the
Class A Certificateholder surrendering such Class A Certificates. No service
charge may be imposed for any such exchange but the Servicer or Transfer Agent
and Registrar may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.

The Servicer, the Trustee, the Paying Agent and the Transfer Agent and Registrar
and any agent of any of them, may treat the person in whose name this Class A
Certificate is registered as the owner hereof for all purposes, and neither the

in certain circumstances described in the Agreement.

This certifies that [ ] (the "Class B Certificateholder") is the registered
owner of a fractional undivided interest in certain assets of a trust (the
"Trust") created pursuant to the Pooling and Servicing Agreement dated as of May
29, 1991 (as amended and supplemented, the "Agreement"), as supplemented by the

This Class B Certificate is issued under and is subject to the terms, provisions
and conditions of the Agreement and the Series Supplement, to which Agreement
and Series Supplement, each as amended and supplemented from time to time, the
Class B Certificateholder by virtue of the acceptance hereof assents and is
bound.

It is the intent of the Sellers and the Investor Certificateholders that, for
Federal, state and local income and franchise tax purposes only, the Investor
Certificates will qualify as indebtedness of the Sellers secured by the
Receivables. The Class B Certificateholder, by the acceptance of this Class B
Certificate, agrees to treat this Class B Certificate for Federal, state and
local income and franchise tax purposes as indebtedness of the Sellers.

In general, payments of principal with respect to the Class B Certificates are
limited to the Class B Invested Amount, which may be less than the unpaid
principal balance of the Class B Certificates, except that principal payments
may be made in excess of the Class B Invested Amount to the extent amounts are
available for that purpose in the Cash Collateral Account. The Class B Expected
Final Payment Date is the February 2003 Distribution Date, but principal with
respect to the Class B Certificates may be paid earlier or later under certain
circumstances described in the Agreement and the Series Supplement. Principal
payments with respect to the Class B Certificates will not commence until the
Class A Invested Amount is paid in full. In addition, the final payment of
principal of the Class B Certificates will occur later than the Class B Expected
Final Payment Date if Collections of Receivables allocable to pay principal of
the Class B Certificates are insufficient to pay the Class B Invested Amount on
or prior to such Distribution Date. If the principal of the Class A Certificates
and the Class B Certificates is not paid in full on or prior to the Termination
Date, the Trustee will sell or cause to be sold on such Termination Date
Principal Receivables (and the related Finance Charge Receivables) (or interests
therein) in an amount equal to 110% of the Invested Amount as of such
Termination Date, subject to certain limitations, and shall immediately deposit
the Termination Proceeds allocable to the Series 1998-3 Certificateholders'
Interest in the Collection Account. The Termination Proceeds shall be allocated
and distributed to the Class A Certificateholders and the Class B
Certificateholders in accordance with the Series Supplement.

governmental charge that may be imposed in connection therewith.
