Certificates representing fractional undivided interests in the Trust.  The
Principal Terms of any new Series are to be set forth in a Supplement to the
Agreement.

          Pursuant to this Supplement, the Seller and the Trustee shall create a
new Series of Investor Certificates and specify the Principal Terms thereof.

                         --------------------------------- 

          (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 preceding Record Date;
provided, however, that, with respect to the first Distribution Date, Class A
- --------  -------                                                            
Monthly Interest shall be equal to $ 2,668,618.75; and provided further, that
                                                       -------- -------      
with respect to the first Distribution Date following the Monthly Period in
which an Additional Issuance Date occurs, Class A Monthly Interest shall be
increased by the amount of interest accrued at the Class A Certificate Rate on
the increase in the outstanding principal balance of the Class A Certificates as
a result of such Additional Issuance from and including such Additional Issuance
Date to but excluding such Distribution Date.

          On the Determination Date preceding each Payment Date, the Servicer
shall determine the excess, if any (the "Class A Interest Shortfall"), of (x)
the Class A Monthly Interest for the Interest Period applicable to such Payment
Date over (y) the aggregate amount of funds allocated and available to pay such
     ----                                                                      
Class A Monthly Interest 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 Penalty Rate and (ii) such Class A Interest Shortfall (or the
portion thereof which has not been 

                                       20

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.

          (b) The amount of monthly interest ("Class B Monthly Interest")
distributable from the Collection Account with respect to the Class B
Certificates on any Distribution Date shall be an amount equal to the product of
(i) a fraction, the numerator of which is the actual number of days from and
including the preceding Distribution Date (or, for the first Distribution Date,
the Closing Date) to but excluding such Distribution Date, and the denominator
of which is 360, (ii) the Class B Certificate Rate and (iii) the outstanding
principal balance of the Class B Certificates as of the preceding Record Date;
provided, however, that with respect to the first Distribution Date following
- --------  -------                                                            
the Monthly Period in which an Additional Issuance Date occurs, Class B Monthly
Interest shall be increased by the amount equal to the product of (a) a
fraction, the numerator of which is the actual number of days in the period from
and including such Additional Issuance Date to but excluding such Distribution
Date and the denominator of which is 360, (b) the Class B Certificate Rate and
(c) the increase in the outstanding principal balance of the Class B
Certificates as a result of such Additional Issuance.

          On the Determination Date preceding each Payment Date, the Servicer
shall determine the excess, if any (the "Class B Interest Shortfall"), of (x)
the Class B Monthly Interest for the Interest Period applicable to such Payment
Date over (y) the aggregate amount of funds allocated and available to pay such
     ----                                                                      
Class B Monthly Interest 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 the product of (i) a fraction,
the numerator of which is the actual number of days from and including the
preceding Distribution Date to but excluding such Distribution Date and the
denominator of which is 360, (ii) the Class B Penalty Rate and (iii) 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.

          (c) The amount of monthly interest ("Class C Monthly Interest")
distributable from the Collection Account with respect to the Class C Interests
on any Distribution Date shall be an amount equal to the product of (i) (A) a
fraction, the numerator of which is the actual number of days in the period from
and including the preceding Distribution Date to but excluding such Distribution
Date and the denominator of which is 360, times (B) the Class C Interest Rate
and (ii) the outstanding principal balance of the Class C Interests as of the
preceding Record Date; provided, however, with respect to the first Distribution
                       --------  -------                                        
Date, Class C Monthly Interest shall be equal to the interest accrued on the
Class C Initial Invested Amount at the Class C Interest Rate for the period from
the Closing Date to but excluding the first Distribution Date.

          On the Determination Date preceding each Distribution Date, the
Servicer shall determine the excess, if any (the "Class C Interest Shortfall"),
of (x) the Class C Monthly Interest for such Distribution Date over (y) the
                                                               ----        
aggregate amount of funds allocated and available to pay such Class C Monthly
Interest on such Distribution Date (including the proceeds of any draw made on
the Class C Spread Account as provided in the Loan Agreement).  If the Class C
Interest Shortfall with respect to any Distribution Date is greater than zero,
an additional amount ("Class C Additional Interest") equal to the product of (i)
a fraction, the numerator of which is the actual number of days in the period
from and including the preceding Distribution Date to but excluding such
Distribution Date and the denominator of which is 360, (ii) the Class C Interest
Rate and (iii) such Class C Interest Shortfall (or the portion thereof which has
not been paid to the Class C Interest Holders) shall be payable as provided
herein with respect to the Class C Interests on each Distribution Date following
such Distribution Date to and including the Distribution Date on which such
Class C Interest Shortfall is paid to the Class C Interest Holders.
Notwithstanding anything to the contrary herein, Class C Additional Interest
shall be payable or distributed to the Class C Interest Holders only to the
extent permitted by applicable law.

Accounts; Class A Accumulation Period.
- ------------------------------------- 

          (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
with respect to the Class A Accumulation Period, shall be equal to the least of
(x) the Available Investor Principal Collections on deposit in the Collection
Account with respect to such Distribution Date, (y) for each Distribution Date
with respect to the Class A Accumulation Period (and on or prior to the Class A
Expected Final Payment Date), the Controlled Deposit Amount for such
Distribution Date and (z) the Class A Adjusted Invested Amount on such
Distribution Date.

          (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 lesser of (x) 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) and
(y) the Class B Invested Amount on such Distribution Date.

          (c) The amount of monthly principal ("Class C Monthly Principal")
distributable from the Collection Account with respect to the Class C Invested
Amount on each Distribution Date, beginning with the Class C Principal
Commencement Date, shall be equal to the lesser of (x) 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
                   -----

          (d)(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
       "Principal Funding Account"), bearing a designation clearly indicating
       that the funds deposited therein are held for the benefit of the Class A
       Certificateholders.  The Principal Funding Account shall initially be
       established with Harris Trust and Savings Bank.

          (ii)   At the direction of the Servicer, funds on deposit in the
       Principal Funding Account shall be invested by 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 losses and investment expenses)
       ("Principal Funding Investment Proceeds") on funds on deposit therein
       shall be applied as set forth in paragraph (iii) below.  Funds on deposit
       in the 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.  No Eligible Investment shall be disposed of prior to
       its maturity; provided, however, that the Trustee may sell, liquidate or
                     --------  -------                                         
       dispose of an Eligible Investment before its maturity, if so directed by
       the Servicer, the Servicer having reasonably determined that the interest
       of the Class A Certificateholders may be adversely affected if such
       Eligible Investment is held to its maturity.  Unless the Servicer directs
       otherwise, funds deposited in the 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 Class A
       Accumulation Period, the Servicer shall direct the Trustee to withdraw
       from the Principal Funding Account and deposit into the Collection
       Account all Principal Funding Investment Proceeds then on deposit in the
       Principal Funding Account and such Principal Funding Investment Proceeds
       shall be treated as a portion of Class A Available Funds.

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

          (e)(i) The Trustee shall possess all right, title and interest in all
       funds on deposit from time to time in the Principal Funding Account and
       in all proceeds thereof.  The Principal Funding Account shall be under
       the sole dominion and control of the Trustee for the benefit of the Class
       A Certificateholders.  If, at any time, the Principal Funding Account
       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 Principal Funding Account meeting the conditions
       specified in paragraph (d)(i) above as an Eligible Deposit Account and
       shall transfer any cash and/or any investments to such new Principal
       Funding Account.

          (ii) Pursuant to the authority granted to the Servicer in Section
       3.01(b) of the Agreement, the Servicer shall have the power, revocable by
       the Trustee, to make withdrawals and payments or to instruct the Trustee
       to make withdrawals and payments from the Principal Funding Account for
       the purposes of carrying out the Servicer's or Trustee's duties
       hereunder.  Pursuant to the authority granted to the Paying Agent in
       Section 5.01 of this Supplement and Section 6.07 of the Agreement, the
       Paying Agent shall have the power, revocable by the Trustee, to withdraw
       funds from the Principal Funding Account for the purpose of making
       distributions to the Class A Certificateholders.

          (f)  The Class A Accumulation Period is scheduled to commence at the
close of business on the last day of February 2002; provided, however, that if
                                                    --------  -------         
the Class A Accumulation Period Length on any Determination Date (determined as
described below) is less than twenty months, upon notice to the Trustee, the
Seller and each Rating Agency, the Servicer, at its option, may elect to modify
the date on which the Class A Accumulation Period actually commences to the 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 Class A
Accumulation Period Length; provided, however, that (i) the length of the Class
                            --------  -------                                  
A Accumulation Period will not be less than one month; and (ii) notwithstanding
any other provision of this Supplement to the contrary, no election to postpone
the commencement of the Class A Accumulation Period shall be made after a Pay
Out Event (as defined in the related Supplement) shall have occurred and is
continuing with respect to any other Series.  On each Determination Date, the
Servicer will determine the "Class A Accumulation Period Length" which will
equal the number of months such that the Class A Accumulation Period Amount for
the Monthly Period immediately preceding the Class A Expected Final Payment
Date, when aggregated with the Class A Accumulation Period Amounts for each
preceding Monthly Period, will equal or exceed the Class A Initial Invested
Amount.  Any notice by the Servicer electing to modify the commencement of the
Class A Accumulation Period pursuant to this subsection (f) shall specify (i)
the Class A Accumulation Period Length, (ii) the commencement date of the Class
A Accumulation Period and (iii) the Controlled Accumulation Amount with respect
to each Monthly Period during the Class A Accumulation Period.

          Section 4.04.  Required Amount.
                         --------------- 

          (a)  With respect to each Distribution Date, on the related
Determination Date, the Servicer shall determine the amount (the "Class A
Required Amount"), if any, by which (x) the sum of (i) Class A Monthly Interest
for such Distribution Date, (ii) any Class A Outstanding Monthly Interest, (iii)
any Class A Additional Interest for such Distribution Date and any Class A
Outstanding Additional Interest, (iv) the Class A Servicing Fee for such
Distribution Date, (v) any Class A Servicing Fee previously due but not paid to
the Servicer and (vi) the Class A Investor Default Amount, if any, for such
Distribution Date exceeds (y) the Class A Available Funds.  In the event that
the Class A Required Amount for such Distribution Date is greater than zero, the
Servicer shall give written notice to the Trustee of such positive Class A
Required Amount on the date of computation and all or a portion of the Excess
Spread and the Excess Finance Charges allocable to Series 1998-4 with respect to
the related Monthly Period in an 

                                       24
<PAGE>
 
amount equal to the Class A Required Amount for such Distribution Date shall be
distributed from the Collection Account on such Distribution Date pursuant to
Section 4.07(a). In the event that the Class A Required Amount for such
Distribution Date exceeds the amount of Excess Spread and the amount of Excess
Finance Charges allocable to Series 1998-4 with respect to the related Monthly
Period, all or a portion of the Available Cash Collateral Amount with respect to
such Distribution Date in an amount equal to such excess shall be applied to
fund the Class A Required Amount. In the event that the Class A Required Amount
for such Distribution Date exceeds the amount of Excess Spread, the amount of
Excess Finance Charges allocable to Series 1998-4 with respect to the related
Monthly Period and the Available Cash Collateral Amount with respect to such
Distribution Date, all or a portion of the Reallocated Principal Collections
with respect to such Monthly Period in an amount equal to such excess shall be
distributed from the Collection Account on such Distribution Date pursuant to
Section 4.08(a).

          (b) With respect to each Distribution Date, on the related
Determination Date, the Servicer shall determine the amount (the "Class B
Required Amount") equal to the sum of (x) the amount, if any, by which (A) the
sum of (i) Class B Monthly Interest for such Distribution Date, (ii) any Class B
Outstanding Monthly Interest, (iii) any Class B Additional Interest for such
Distribution Date and any Class B Outstanding Additional Interest, (iv) the
Class B Servicing Fee for such Distribution Date and (v) any Class B Servicing
Fee previously due but not paid to the Servicer exceeds (B) the Class B
Available Funds and (y) the Class B Investor Default Amount for such
Distribution Date.  In the event that the difference between the Class B
Required Amount for such Distribution Date and the Excess Spread and Excess
Finance Charges applied with respect thereto pursuant to subsection 4.07(c) on
such Distribution Date is greater than zero, the Servicer shall give written
notice to the Trustee of such excess Class B Required Amount on the date of
computation and all or a portion of the Available Cash Collateral Amount with
respect to such Distribution Date pursuant to Section 4.12(c) shall be applied
to fund such excess Class B Required Amount.  In the event that the Class B
Required Amount for such Distribution Date exceeds the portion of Excess Spread
and Excess Finance Charges allocated to Series 1998-4 with respect to such
Monthly Period and not used to fund the Class A Required Amount and the portion
of the Available Cash Collateral Amount with respect to such Distribution Date
withdrawn from the Cash Collateral Account to fund the Class B Required Amount,
then a portion of the Reallocated Principal Collections with respect to such
Monthly Period shall be distributed from the Collection Account on such
Distribution Date pursuant to Section 4.08(b).

       Distribution Date shall be treated as a portion of Available Investor
       Principal Collections for such Distribution Date; and

          (iv)   the balance, if any, shall constitute Excess Spread and shall
       be allocated and distributed as set forth in Section 4.07.

       accordance with Section 4.03 of the Agreement); and

          (iii)  the balance, if any, shall constitute Excess Spread and shall
       be allocated and distributed as set forth in Section 4.07.

          Section 4.06.  Defaulted Amounts; Investor Charge-Offs.
                         --------------------------------------- 

          (a) On each Determination Date, the Servicer shall calculate the Class
A Investor Default Amount, if any, for the related Distribution Date.  If, on
any Distribution Date, the Class A Required Amount for the related Monthly
Period exceeds the sum of (x) the amount of Reallocated Principal Collections
with respect to such Monthly Period, (y) the amount of Excess Spread and the
Excess Finance Charges allocable to Series 1998-4 with respect to such
Distribution Date and (z) the Available Cash Collateral Amount with respect to
such Distribution Date, the Class C Invested Amount will be reduced by the
amount of such excess, but not by more than the excess of the Class A Investor
Default Amount for such Distribution Date over the amount of Reallocated
                                          ----                          
Principal Collections, the amount of Excess Spread and Excess Finance Charges
and the amount withdrawn from the Cash Collateral Account used to fund the Class
A Investor Default Amount for such Distribution Date.  In the event that such
reduction would cause the Class C Invested Amount to be a negative number, the
Class C Invested Amount will be reduced to zero and the Class B Invested Amount
shall be reduced by the amount by which the Class C 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 Class C Invested Amount with respect to such
Distribution Date and the amount of Reallocated Principal Collections, the
amount of Excess Spread and Excess Finance Charges and the amount withdrawn from
the Cash Collateral Account used to fund the Class A Investor Default Amount for
such Distribution Date.  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 shall 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
                  ----                                                       
Class C Invested Amount and the Class B Invested Amount for such Distribution
Date and the amount of Reallocated Principal Collections, the amount of Excess
Spread and Excess Finance Charges and the amount withdrawn from the Cash
Collateral Account used to fund the Class A Investor Default Amount for such
Distribution Date (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 unreimbursed Class A Investor
Charge-Offs) on any Distribution Date by the amount of Excess Spread and Excess
Finance Charges allocated and available for that purpose pursuant to Section
4.07(b).

          (b) On each Determination Date, the Servicer shall calculate the Class
B Required Amount, if any, for the related Distribution Date.  If, on any
Distribution Date, the Class B Required Amount for such Distribution Date
exceeds the sum of (x) the amount of Excess Spread and Excess Finance Charges
allocated to Series 1998-4 with respect to the related Monthly Period which are
not used to fund the Class A Required Amount and Class A Investor Charge-Offs on
the related Distribution Date, (y) the portion, if any, of the Available Cash
Collateral Amount to be withdrawn from the Cash Collateral Account pursuant to
Section 4.12(c) which is remaining after applying such amounts to fund any
deficiency of amounts payable pursuant to Section 4.07(a) with respect to such
Distribution Date and (z) the amount of Reallocated Principal Collections which
are available to fund the Class B Required Amount on such Distribution Date
pursuant to Section 4.08(b), then the Class C Invested Amount shall be 

                                       28
<PAGE>
 
reduced by the amount of such excess, but not by more than the excess of the
Class B Investor Default Amount for such Distribution Date over the amount of
                                                           ----              
Reallocated Principal Collections, the amount of Excess Spread and Excess
Finance Charges, and the amount withdrawn from the Cash Collateral Account used
to fund the Class B Investor Default Amount for such Distribution Date.  In the
event that such reduction would cause the Class C Invested Amount to be a
negative number, the Class C Invested Amount shall be reduced to zero, and the
Class B Invested Amount shall be reduced by the amount by which the Class C
Invested Amount would have been reduced below zero, but not by more than the
excess, if any, of the Class B Investor Default Amount for such Distribution
Date over the amount of such reduction, if any, of the Class C Invested Amount
     ----                                                                     
with respect to such Distribution Date and the amount of Reallocated Principal
Collections, the amount of Excess Spread and Excess Finance Charges, and the
amount withdrawn from the Cash Collateral Account used to fund the Class B
Investor Default Amount for such Distribution Date (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 unreimbursed Class B Investor Charge-Offs) on any Distribution Date by
the amount of Excess Spread and Excess Finance Charges allocated and available
for that purpose pursuant to Section 4.07(d).

          (c) If, on any Distribution Date, Reallocated Principal Collections
for such Distribution Date are applied pursuant to Section 4.08(a) or (b), the
Class C Invested Amount shall be reduced by the amount of such Reallocated
Principal Collections.  In the event that such reduction would cause the Class C
Invested Amount to be a negative number, the Class C Invested Amount shall be
reduced to zero, and the Class B Invested Amount shall be reduced by the amount
by which the Class C Invested Amount would have been reduced below zero.

          (d) If, on any Distribution Date, the Class C Investor Default Amount
exceeds the sum of (x) the amount of Excess Spread and Excess Finance Charges
available to fund the Class C Investor Default Amount pursuant to Section
4.07(g) on such Distribution Date, (y) the portion, if any, of the Available
Cash Collateral Amount to be withdrawn from the Cash Collateral Account to fund
the Class C Investor Default Amount pursuant to Section 4.07(g) on such
Distribution Date and (z) funds withdrawn from the Class C Spread Account
pursuant to the Loan Agreement to fund the Class C Investor Default Amount, then
the Class C Invested Amount shall be reduced by the amount of such excess;
provided, however, that the Class C Invested Amount shall not be reduced below

Distribution Date, Excess Spread and Excess Finance Charges allocated to Series
1998-4 with respect to the related Monthly Period, to make the following

     Charges allocated to Series 1998-4 and available to pay such amount
     pursuant to this clause (c), such Excess Spread and Excess Finance Charges
     shall be applied first to pay amounts due with respect to such Distribution
     Date pursuant to Section 4.05(b)(i), second to pay the Class B Servicing
     Fee pursuant to Section 4.05(b)(ii) and third as a portion of Available

attributable to Shared Principal Collections or Excess Shared Principal

Subordinated Excess Principal Shortfall of Series 1998-4 for such Distribution
Date and (ii) the product of (x) Excess Shared Principal Collections and (y) a

                         --------------- 

          (a) The Servicer shall establish and maintain, in the name of the
Trustee, on behalf of the Trust, for the benefit of the Class A
Certificateholders, an Eligible Deposit Account (the "Reserve Account") bearing
a designation clearly indicating that the funds deposited therein are held for
the benefit of the Class A Certificateholders.  The Reserve Account shall
initially be established with The Bank of New York.  The Trustee shall possess
all right, title and interest in all funds on deposit from time to time in the
Reserve Account and in all proceeds thereof.  The 

                                       33
<PAGE>
 
Reserve Account shall be under the sole dominion and control of the Trustee for
the benefit of the Class A Certificateholders. If at any time the Reserve
Account 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 Reserve Account meeting the conditions specified above as an Eligible
Deposit Account, and shall transfer any cash and/or any investments to such new
Reserve Account. The Trustee, at the direction of the Servicer, shall (i) make
withdrawals from the Reserve Account from time to time in an amount up to the
Available Reserve Account Amount at such time, for the purposes set forth in
this Supplement, and (ii) on each Distribution Date (from and after the Reserve
Account Funding Date) prior to the termination of the Reserve Account make a
deposit into the Reserve Account in the amount specified in, and otherwise in
accordance with, Section 4.07(j).

          (b) Funds on deposit in the Reserve Account shall be invested at the
direction of the Servicer by the Trustee in Eligible Investments.  Funds on
deposit in the Reserve Account on any Transfer Date, after giving effect to any
withdrawals from the Reserve 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 Trustee shall
maintain for the benefit of the Class A Certificateholders possession of the
negotiable instruments or securities, if any, evidencing such Eligible
Investments.  No Eligible Investment shall be disposed of prior to its maturity;
provided, however, that the Trustee may sell, liquidate or dispose of an
- --------  -------                                                       
Eligible Investment before its maturity, if so directed by the Servicer, the
Servicer having reasonably determined that the interest of the Class A
Certificateholders may be adversely affected if such Eligible Investment is held
to its maturity.  On each Distribution Date, all interest and earnings (net of
losses and investment expenses) accrued since the preceding Distribution Date on
funds on deposit in the Reserve Account shall be retained in the Reserve Account
(to the extent that the Available Reserve Account Amount is less than the
Required Reserve Account Amount) and the balance, if any, shall be deposited in
the Collection Account and treated as Collections of Finance Charge Receivables
allocable to Series 1998-4.  For purposes of determining the availability of
funds or the balance in the Reserve Account for any reason under this
Supplement, except as otherwise provided in the preceding sentence, investment
earnings on such funds shall be deemed not to be available or on deposit.

          (c) On the Determination Date preceding each Distribution Date with
respect to the Class A Accumulation Period and the first Special Payment Date,
the Servicer shall calculate the "Reserve Draw Amount" which shall be equal to
the excess, if any, of the Covered Amount with respect to such Distribution Date
or Special Payment Date over the Principal Funding Investment Proceeds with
                        ----                                               
respect to such Distribution Date or Special Payment Date; provided that such
                                                           --------          
amount will be reduced to the extent that funds otherwise would be available for
deposit in the Reserve Account under Section 4.07(j) with respect to such
Distribution Date or Special Payment Date.

          (d) In the event that for any Distribution Date the Reserve Draw
Amount is greater than zero, the Reserve Draw Amount, up to the Available
Reserve Account Amount, shall be withdrawn from the Reserve Account on the
related Transfer Date by the Trustee (acting 

                                       34
<PAGE>
 
in accordance with the instructions of the Servicer), deposited into the
Collection Account and included in Class A Available Funds.

          (e) In the event that the Reserve Account Surplus on any Distribution
Date, after giving effect to all deposits to and withdrawals from the Reserve
Account with respect to such Distribution Date, is greater than zero, the
Trustee, acting in accordance with the instructions of the Servicer, shall
withdraw from the Reserve Account, and pay to the Seller, an amount equal to
such Reserve Account Surplus.

          (f) Upon the earliest to occur of (i) the termination of the Trust
pursuant to Article XII of the Agreement, (ii) the day on which the Class A
Invested Amount is paid in full to the Class A Certificateholders, (iii) if the
Class A Accumulation Period has not commenced, the occurrence of a Pay Out Event
with respect to Series 1998-4 and (iv) if the Class A Accumulation Period has
commenced, the earlier of the first Special Payment Date and the Class A
Expected Final Payment Date, the Trustee, acting in accordance with the
instructions of the Servicer, after the prior payment of all amounts owing to
the Class A Certificateholders which are payable from the Reserve Account as
provided herein, shall withdraw from the Reserve Account and pay to the Seller
all amounts, if any, on deposit in the Reserve Account and the Reserve Account
shall be deemed to have terminated for purposes of this Supplement.

          Section 4.12.  Cash Collateral Account.
                         ----------------------- 

          (a) The Servicer shall establish and maintain, in the name of the
Trustee, on behalf of the Trust, for the benefit of the Series 1998-4
Certificateholders and the Class C Interest Holders, as their interests appear
herein and in the Loan Agreement, an Eligible Deposit Account (the "Cash
Collateral Account") bearing a designation clearly indicating that the funds
deposited therein are held for the benefit of the Series 1998-4
Certificateholders and the Class C Interest Holders.  The Cash Collateral
Account shall initially be established with the Trustee.  The Trustee shall
possess all right, title and interest in all funds on deposit from time to time
in the Cash Collateral Account and in all proceeds thereof.  The Cash Collateral
Account shall be under the sole dominion and control of the Trustee for the
benefit of the Series 1998-4 Certificateholders and the Class C Interest
Holders.  The interest of the Class C Interest Holders in the Cash Collateral
Account shall be subordinated to the interests of the Series 1998-4
Certificateholders as provided herein and in the Loan Agreement.  If at any time
the Cash Collateral Account 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 Cash Collateral Account meeting the conditions
specified above as an Eligible Deposit Account, and shall transfer any cash
and/or any investments to such new Cash Collateral Account.  The Trustee, at the
direction of the Servicer, shall make deposits to and withdrawals from the Cash
Collateral Account in the amounts and at the times set forth in this Supplement
and the Loan Agreement.   All withdrawals from the Cash Collateral Account shall
be made in the priority set forth below.  The Class C Interest Holders shall not
be entitled to reimbursement from the Trust Assets for any withdrawals from the
Cash Collateral Account except as specifically provided in this Supplement and
the Loan Agreement.

                                       35
<PAGE>
 
          (b) On the Closing Date, the Trustee shall deposit the Initial Cash
Collateral Amount received by it from the Seller in immediately available funds
into the Cash Collateral Account.  Funds on deposit in the Cash Collateral
Account shall be invested at the direction of the Servicer 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 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.  No Eligible Investment shall be
disposed of prior to its maturity; provided, however, that the Trustee may sell,
                                   --------  -------                            
liquidate or dispose of an Eligible Investment before its maturity, if so
directed by the Servicer, the Servicer having reasonably determined that the
interest of the 1998-4 Certificateholders may be adversely affected if such
Eligible Investment is held to its maturity.  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 1998-4 Certificateholders and the Class C Interest
Holders 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 Seller.  For purposes of determining the availability of funds or
the balances in the Cash Collateral Account for any reason under this
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") by which the amounts specified in clauses
(a) through (g) of Section 4.07 with respect to the related Distribution Date
exceed the amount of Excess Spread and Excess Finance Charges allocated with
respect to the related Monthly Period.  In the event that for any Distribution
Date the Required Draw Amount is greater than zero, the Servicer shall give
written notice to the Trustee, in substantially the form of Exhibit B, of such
positive Required Draw Amount on the related Determination Date.  On the related
Transfer Date, the Required Draw Amount, if any, up to the Available Cash
Collateral Amount shall be withdrawn from the Cash Collateral Account and
distributed to fund any deficiency pursuant to Section 4.07(a) through (g) (in
the order of priority set forth in Section 4.07).

          (d) In the event that the Cash Collateral Surplus on any Distribution
Date, after giving effect to all deposits to and withdrawals from the Cash
Collateral Account with respect to such Distribution Date, is greater than zero,
the Trustee, acting in accordance with the instructions of the Servicer, shall
withdraw from the Cash Collateral Account, and apply in accordance with the Loan
Agreement, an amount equal to such Cash Collateral Surplus.

Principal Receivables and the related Finance Charge Receivables (or interests
therein) in an amount equal to the Invested Amount at the close of business on
the last day of the Monthly Period preceding the Termination Date (after giving
effect to all distributions required to be made on the Termination Date, except
pursuant to this Section 7.02).  Such bids shall require that such sale shall
(subject to Section 7.02(b)) occur on the Termination Date.  The Seller shall be

bid submitted in connection with, such bidding process.

          (b)   The Servicer, on behalf of the Trustee, shall sell such

allocable to Finance Charge Receivables and the amount of such proceeds which
are allocable to Principal Receivables.  During the period from the November
2006 Distribution Date to the Termination Date, the Servicer shall continue to
collect payments on the Receivables and allocate and deposit such collections in
accordance with the provisions of the Agreement and the Supplements.

authenticate the Investor Certificates of a new Series and to execute and
deliver the related Supplement shall be subject to the conditions set forth in
Section 6.03(b) of the Agreement and to the additional condition that, as of the
Series Issuance Date and after giving effect to such issuance, the aggregate
amount of Principal Receivables equals or exceeds the Required Principal
Balance.

          Section 9.02.  Addition of Accounts.
                         -------------------- 

          (i)  If, as of the close of business on the last Business Day of any
     Monthly Period, the aggregate amount of Principal Receivables is less than
     the Required Principal Balance on such date, the Seller shall on or prior
     to the close of business on the 10th Business Day following the last
     Business Day of such Monthly Period (the "Required Designation Date"),
     unless the aggregate amount of Principal Receivables exceeds the Required
     Principal Balance as of the close of business on any day after the last
     Business Day of such Monthly Period and prior to the Required Designation
     Date, designate additional Eligible Accounts to be included as Accounts as
     of the Required Designation Date or any earlier date in a sufficient amount
     such that, after giving effect to such addition, the aggregate amount of
     Principal Receivables equals or exceeds the Required Principal Balance on
     such date.  Each such addition shall be subject to the same conditions
     applicable to any Addition required to be made pursuant to Section 2.08(a)
     of the Agreement.  The failure of any condition set forth in Section
     2.08(c) or (d) of the Agreement, as the case may be, shall not relieve the
     Seller of its obligation pursuant to this paragraph; provided, however,
                                                          --------  ------- 
     that the failure of the Seller to transfer Receivables to the Trust as
     provided in this paragraph solely as a result of the unavailability of a
     sufficient amount of Eligible Receivables shall not constitute a breach of
     this Supplement; provided further, that any such failure which has not been
                      -------- -------                                          
     timely cured will nevertheless result in the occurrence of a Pay Out Event
     with respect to Series 1998-4.

          (ii) In lieu of, or in addition to, designating Additional Accounts
     pursuant to clause (i) above, the Seller may, subject to the conditions
     specified in Section 2.03(d) of the Agreement, convey to the Trust
     Participation Interests.  The addition of Participation Interests in the
     Trust pursuant to this paragraph shall be effected by an amendment to the
     Agreement and this Supplement, dated the applicable Addition Date, pursuant
     to Section 13.01(a) of the Agreement.

                     Class A Expected Final Payment Date:
                      The November 2003 Distribution Date

                 Each $1,000 minimum denomination represents a
                         1/631,875 undivided interest
                           in certain assets of the

                           CAPITAL ONE MASTER TRUST

Evidencing an undivided interest in a trust, the corpus of which consists
primarily of receivables generated from time to time in the ordinary course of
business in a portfolio of consumer revolving credit card accounts by

                               CAPITAL ONE BANK

and, in certain circumstances, certain Additional Sellers (as defined in the
Pooling and Servicing Agreement referred to below).

            (Not an interest in or obligation of Capital One Bank,
                any Additional Seller or any affiliate thereof)

          This certifies that CEDE & CO. (the "Class A Certificateholder") is
the registered owner of a fractional undivided interest in certain assets of a
trust (the "Trust") created pursuant 

                                     A-1-1
<PAGE>
 
to the Pooling and Servicing Agreement dated as of September 30, 1993 (as
amended and supplemented, the "Agreement"), as supplemented by the Series
1998-4 Supplement dated as of November 17, 1998 (as amended and supplemented,
the "Series Supplement"), among Capital One Bank, as Seller and Servicer, and
The Bank of New York, a New York banking corporation, as trustee (the
"Trustee"). The corpus of the Trust consists of (i) a portfolio of all
receivables (the "Receivables") existing in the consumer revolving credit card
accounts and other consumer revolving credit 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 accountholders 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) an interest in any Funds Collateral relating to secured
accounts, (vi) the benefits of any Series Enhancement and (vii) all other assets
and interests constituting the Trust. The Holder of this Class A Certificate is
entitled to the benefit of funds on deposit in a Cash Collateral Account and any
Series Enhancement 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 Seller 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 Seller 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 Seller.

          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 November 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 

                                     A-1-2
<PAGE>
 
one or more months during the Class A Accumulation Period there are not
sufficient funds to pay the Controlled Deposit Amount, then to the extent that
excess funds are not available on subsequent Distribution Dates with respect to
the Class A 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.

          Unless the certificate of authentication hereon has been executed by
or on behalf of the Trustee, by manual signature, this Class A Certificate shall
not be entitled to any benefit under the Agreement or the Series Supplement or
be valid for any purpose.

          IN WITNESS WHEREOF, the Seller has caused this Class A Certificate to
be duly executed.

                    CLASS A 5.43% ASSET BACKED CERTIFICATE

                        Summary of Terms and Conditions


          The Receivables consist of Principal Receivables which arise generally
from the purchase of goods and services and amounts advanced to accountholders
as cash advances and Finance Charge Receivables.  This Class A Certificate is
one of a Series of Investor Certificates entitled "Capital One Master Trust,
Series 1998-4."  The Series 1998-4 Certificates are being issued in two Classes,
the first of which is known as the "Class A 5.43% Asset Backed Certificates,
Series 1998-4" (the "Class A Certificates") and the second Class is known as the
"Class B Floating Rate Asset Backed Certificates, Series 1998-4" (the  "Class B
Certificates").  In addition, as part of Series 1998-4, the Trust is creating a
third Class of uncertificated interests in the Trust which uncertificated
interests, except as expressly provided in the Series Supplement, are deemed to
be "Investor Certificates" and are known as the "Class C Floating Rate Asset
Backed Interests, Series 1998-4" (the "Class C Interests").  This Class A
Certificate 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 Seller's Interest.  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 $631,875,000.  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 the Class A
Certificateholders on or prior to such date, minus (c) the excess, if any, of
the aggregate amount of Class A Investor Charge-Offs for all prior Distribution
Dates over the aggregate amount of Class A Investor Charge-Offs reimbursed
pursuant to Section 4.06(a) of the Series Supplement prior to such date.  Also,
a Seller's Certificate has been issued to Capital One Bank pursuant to the
Agreement which represents the Seller's Interest on the date hereof.

          Subject to the terms and conditions of the Agreement, the Seller 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 (including amounts on deposit in the Collection Account and the
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 

                                     A-1-5
<PAGE>
 
(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 agency specified in the notice of final
distribution delivered by the Trustee to the Class A Certificateholders in
accordance with the Agreement and the Series Supplement.

          On any day occurring on or after the day on which the Invested Amount
is reduced to 5% or less of the Initial Invested Amount, the Seller has the
option to repurchase the Certificateholders' Interest in the Trust.  The
repurchase price will be equal to (a) if such day is a Distribution Date, the
Reassignment Amount for such Distribution Date or (b) if such day is not a
Distribution Date, the Reassignment Amount for the Distribution Date following
such day.  Following the deposit of the Reassignment Amount in the Collection
Account, Class A Certificateholders, the Class B Certificateholders and the
Class C Interest Holders will not have any interest in the Receivables and the
Class A Certificates will represent only the right to receive such Reassignment
Amount.

          This Class A Certificate does not represent an obligation of, or an
interest in, the Seller, 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
right of payment to certain Collections with respect to the Receivables (and
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 Seller, the Servicer and the Trustee without Certificateholder
consent. The Trustee may, but shall not be obligated to, enter into any such
amendment which affects the Trustee's rights, duties or immunities under the
Agreement or otherwise.

          The Agreement or any Supplement may also be amended from time to time
by the Servicer, the Seller and the Trustee, with the consent of the Holders of
Investor 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, (ii) change the definition of or the manner of calculating
the interest of any Investor Certificateholder without the consent of each
affected Investor Certificateholder, (iii) reduce the aforesaid percentage
required to consent to any such amendment without the consent of each Investor
Certificateholder or (iv) adversely affect the rating of any Series or Class by
each Rating Agency without the consent of the Holders of Investor Certificates
of such Series or Class evidencing not less than 66-2/3% of the aggregate 

                                     A-1-6
<PAGE>
 
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 the 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 guaranteed, and thereupon one or more new Class A Certificates of
authorized denominations and for the same aggregate fractional undivided
interest will be issued to the designated transferee or transferees.

          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 Servicer nor the Trustee, the Paying Agent, the Transfer Agent and
Registrar, nor any agent of any of them, shall be affected by notice to the
contrary except in certain circumstances described in the Agreement.

          THIS CLASS A CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, 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.

                           CAPITAL ONE MASTER TRUST

Evidencing an undivided interest in a trust, the corpus of which consists
primarily of receivables generated from time to time in the ordinary course of
business in a portfolio of consumer revolving credit card accounts by CAPITAL
ONE BANK and, in certain circumstances, certain Additional Sellers (as defined
in the Pooling and Servicing Agreement referred to below).

            (Not an interest in or obligation of Capital One Bank,
                any Additional Seller or any affiliate thereof)

          This certifies that CEDE & CO. (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 September 30, 1993 (as amended and supplemented, the "Agreement"),
as supplemented by the Series 1998-4 Supplement dated as of November 17, 1998
(as amended and supplemented, the "Series Supplement"), among Capital One Bank,
as Seller and Servicer, and The Bank of New York, a New York banking
corporation, as trustee (the "Trustee").  The corpus of the Trust consists of
(i) a portfolio of all receivables (the "Receivables") existing in the consumer
revolving credit card accounts and other consumer revolving credit 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 accountholders 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) an interest in any Funds
Collateral relating to secured accounts, (vi) the benefits of any Series
Enhancement and (vii) all other assets and interests constituting the Trust.
The Holder of this Class B Certificate is entitled to the benefit of funds on
deposit in a Cash Collateral Account and any Series Enhancement 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 B
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 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 Seller and the Investor Certificateholders
that, for federal, state and local income and franchise tax purposes only, the
Investor Certificates will qualify as 

                                     A-2-2
<PAGE>
 
indebtedness of the Seller 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 Seller.

          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.  The Class B Expected
Final Payment Date is the January 2004 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.

     No Class B Certificate (or any interest therein) may be acquired or held by
any employee benefit or other plan (including an individual retirement account)
that is subject to the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), or Section 4975 of the Internal Revenue Code of 1986, as
amended (each, a "Plan"), any trustee or other person acting on behalf of any
Plan, or any other person using "Plan Assets" to effect such acquisition or
holding (each, a "Plan Investor") unless (i) such acquirer or holder is an
insurance company, (ii) the source of funds used to acquire or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.  By acquiring an interest in this Class B
Certificate, each Class B Certificateholder or Certificate Owner shall be deemed
to have represented, either (i) that it is not a Plan Investor or (ii) that (1)
it is an insurance company, (2) the source of funds used to acquire or hold an
interest in such Certificate is an "insurance company general account" (as such
term is defined in PTCE 95-60), and (3) the conditions set forth in Sections I
and III of PTCE 95-60 have been satisfied.

          Unless the certificate of authentication hereon has been executed by
or on behalf of the Trustee, by manual signature, this Class B Certificate shall
not be entitled to any benefit under the Agreement or the Series Supplement or
be valid for any purpose.

                           CAPITAL ONE MASTER TRUST

                                 SERIES 1998-4

                CLASS B FLOATING RATE ASSET BACKED CERTIFICATE

                        Summary of Terms and Conditions


          The Receivables consist of Principal Receivables which arise generally
from the purchase of goods and services and amounts advanced to accountholders
as cash advances and Finance Charge Receivables.  This Class B Certificate is
one of a Series of Certificates entitled "Capital One Master Trust, Series 
1998-4." The Series1998-4 Certificates are being issued in two Classes, the
first of which is known as the "Class A 5.43% Asset Backed Certificates, Series
1998-4" (the "Class A Certificates") and the second Class is known as the 
"Class B Floating Rate Asset Backed Certificates, Series 1998-4" (the "Class B
Certificates").  In addition, as part of Series 1998-4, the Trust is creating a
third Class of uncertificated interests in the Trust which uncertificated
interests, except as expressly provided in the Series Supplement, are deemed to
be "Investor Certificates" and are known as the "Class C Floating Rate Asset
Backed Interests, Series 1998-4" (the "Class C Interests").  This Class B
Certificate 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 Seller's Interest.  The aggregate interest represented by the
Class B Certificates at any time in the Principal Receivables in the Trust shall
not exceed an amount equal to the Class B Invested Amount at such time.  The
Class B Initial Invested Amount is $60,000,000.  The Class B Invested Amount on
any date will be an amount equal to (a) the Class B Initial Invested Amount,
minus (b) the aggregate amount of principal payments made to the Class B
Certificateholders on or prior to such date, minus (c) the excess, if any, of
the aggregate amount of Class B Investor Charge-Offs for all prior Distribution
Dates over the aggregate amount of any reimbursement of Class B Investor Charge-
Offs for all Distribution Dates preceding such date, minus (d) the amount of
Reallocated Principal Collections allocated on all prior Distribution Dates
pursuant to Section 4.08(a) of the Series Supplement (excluding any Reallocated
Principal Collections that have resulted in a reduction in the Class C Invested
Amount pursuant to Section 4.06(c) of the Series Supplement), minus (e) an
amount equal to the amount by which the Class B Invested Amount has been reduced
on all prior Distribution Dates pursuant to Section 4.06(a) of the Series
Supplement and plus (f) the amount of Excess Spread and Excess Finance Charges
allocated and available on all prior Distribution Dates pursuant to Section
4.07(d) of the Series Supplement for the purpose of reimbursing amounts deducted
pursuant to the foregoing clauses (c), (d) and (e).  Also, a Seller's
Certificate has been issued to Capital One Bank pursuant to the Agreement which
represents the Seller's Interest on the date hereof.

          Subject to the terms and conditions of the Agreement, the Seller 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.

                                     A-2-6

          On each Payment Date, the Paying Agent shall distribute to each 
Class B Certificateholder of record on the last day of the preceding calendar
month (each a "Record Date") such Class B Certificateholder's pro rata share of
such amounts (including amounts on deposit in the Collection Account and the
Principal Funding Account) as are payable to the Class B Certificateholders
pursuant to the Agreement and the Series Supplement. Distributions with respect
to this Class B Certificate will be made by check mailed to the address of the
Class B Certificateholder of record appearing in the Certificate Register
without the presentation or surrender of this Class B Certificate or the making
of any notation thereon (except for the final distribution in respect of this
Class B Certificate) except that with respect to Class B 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 B Certificate will be made only upon presentation and
surrender of this Class B Certificate at the office or agency specified in the
notice of final distribution delivered by the Trustee to the Class B
Certificateholders in accordance with the Agreement and the Series Supplement.

          On any day occurring on or after the day on which the Invested Amount
is reduced to 5% or less of the Initial Invested Amount, the Seller has the
option to repurchase the Certificateholders' Interest in the Trust.  The
repurchase price will be equal to (a) if such day is a Distribution Date, the
Reassignment Amount for such Distribution Date or (b) if such day is not a
Distribution Date, the Reassignment Amount for the Distribution Date following
such day.  Following the deposit of the Reassignment Amount in the Collection
Account, the Class A Certificateholders, the Class B Certificateholders and the
Class C Interest Holders will not have any interest in the Receivables and the
Class B Certificates will represent only the right to receive such Reassignment
Amount.

          This Class B Certificate does not represent an obligation of, or an
interest in, the Seller, 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 B Certificate is limited in
right of payment to certain Collections with respect to the Receivables (and
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 Seller, the Servicer and the Trustee without Certificateholder
consent. The Trustee may, but shall not be obligated to, enter into any such
amendment which affects the Trustee's rights, duties or immunities under the
Agreement or otherwise.

          The Agreement or any Supplement may also be amended from time to time
by the Servicer, the Seller and the Trustee, with the consent of the Holders of
Investor 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, (ii) change the definition of or the manner of 

                                     A-2-7
<PAGE>
 
calculating the interest of any Investor Certificateholder without the consent
of each affected Investor Certificateholder, (iii) reduce the aforesaid
percentage required to consent to any such amendment without the consent of each
Investor Certificateholder or (iv) adversely affect the rating of any Series or
Class by each Rating Agency 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 the
Agreement or otherwise.

          The Class B Certificates are issuable in minimum denominations of
$1,000 and integral multiples of $1,000.  The transfer of this Class B
Certificate shall be registered in the Certificate Register upon surrender of
this Class B 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 B Certificateholder or such
Class B Certificateholder's attorney, and duly authorized in writing with such
signature guaranteed, and thereupon one or more new Class B Certificates of
authorized denominations and for the same aggregate fractional undivided
interest will be issued to the designated transferee or transferees.

          As provided in the Agreement and subject to certain limitations
therein set forth, Class B Certificates are exchangeable for new Class B
Certificates evidencing like aggregate fractional undivided interests as
requested by the Class B Certificateholder surrendering such Class B
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 B Certificate is registered as the owner hereof for all purposes, and
neither the Servicer nor the Trustee, the Paying Agent, the Transfer Agent and
Registrar, nor any agent of any of them, shall be affected by notice to the
contrary except in certain circumstances described in the Agreement.

          THIS CLASS B CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, 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.
