Servicing Agreement.

          (5)  On each Interest Payment Date (or, following the early

<PAGE>   58

               (x) the Controlled Liquidation Amount and

                   Account on any Distribution Date pursuant to Section 9

Servicer shall cause the Paying Agent to pay such amount to the Investor
Certificateholders of such Class or Subclass in accordance with Section 5.01 of

Class Invested Amount for each Class has been reduced to zero shall be paid to
the Holder of the Seller Certificate.

          (10) On the Class Expected Final Payment Date or the Class Final
Maturity Date, if applicable (or, if such Class Expected Final Payment Date or
Class Final Maturity Date is not also a Distribution Date, on the Distribution
Date occurring in the same calendar month as the Class Expected Final Payment
Date or the Class Final Maturity Date, if applicable), the Master Servicer shall
direct the Trustee in writing to withdraw the amount on deposit in the Series
Principal Funding Account with respect to each Class; provided that (i) such
amount shall be no greater than the Class Invested Amount and (ii) funds, if
any, remaining on deposit in the Series Principal Funding Account after the
payment in full of the Class Invested Amount with respect to each Class shall be
withdrawn and paid to the Holder of the Seller Certificate. The Master Servicer

the Pooling and Servicing Agreement.

     (b)  Payments to the Sellers and/or the Master Servicer. Notwithstanding
the other provisions in Section 9 and this Section 10, any amounts payable to
Discover Bank on behalf of the Holder of the Seller Certificate or to the Master
Servicer on any Distribution Date pursuant to Section 9 and this Section 10 may

     SECTION 11.   Credit Enhancement

     (a)  Initial Credit Enhancement. The Master Servicer hereby represents
with respect to the Initial Credit Enhancement and shall be deemed to represent
with respect to any successor Credit Enhancement that (i) the Master Servicer
has provided for the Credit Enhancement for the account of the Trustee and for
the benefit of the Investor Certificateholders, (ii) the Master Servicer has
entered into a Credit Enhancement Agreement, (iii) the Credit Enhancement
permits the Trustee or the Master Servicer, acting as the Trustee's
attorney-in-fact or otherwise, to make Credit Enhancement Drawings from time to
time in an amount up to the Total Available Credit



                                       48
<PAGE>   60

Enhancement Amount at such time, for the purposes set forth in this Agreement
and (iv) the Credit Enhancement and the respective Credit Enhancement Agreement
may be terminated by the Trustee without penalty if (x) the Master Servicer
elects to obtain a successor Credit Enhancement and such successor Credit
Enhancement does not cause the ratings of the Investor Certificates of the
Series established hereby to be withdrawn or lowered by either of the Rating
Agencies from the respective ratings of such Investor Certificates immediately
prior to such election or (y) if the Credit Enhancement is not Funded Credit
Enhancement, the Credit Enhancement Provider ceases to be a Qualified Credit
Enhancement Provider.

     (b)  Successor Credit Enhancement.

          (i) If the Credit Enhancement is not Funded Credit Enhancement and if,
     at any time, the provider of such Credit Enhancement ceases to be a
     Qualified Credit Enhancement Provider, the Master Servicer shall obtain a
     successor Credit Enhancement within 30 days or such longer period as will
     not result in the lowering or withdrawal of the rating of any Class of any
     Series then outstanding by the Rating Agencies (a) which, if such successor
     Credit Enhancement is not to be Funded Credit Enhancement, will be issued
     by a Qualified Credit Enhancement Provider and (b) with respect to which
     the representations set forth in Section 11(a) will be satisfied; provided,
     however, that the Master Servicer shall not be required to continue efforts
     to obtain a successor Credit Enhancement if the then existing Credit
     Enhancement Provider again becomes a Qualified Credit Enhancement Provider
     and remains such; and, provided, further, that unless otherwise agreed to
     by the Rating Agencies, the Credit Enhancement and Credit Enhancement
     Agreement will not be terminated and no successor Credit Enhancement
     Provider shall be selected if the successor Credit Enhancement, the
     successor Credit Enhancement Agreement, or the selection of such successor
     Credit Enhancement Provider would cause the ratings of the Investor
     Certificates of the Series established hereby to be withdrawn or lowered by
     either Rating Agency from the respective ratings of such Investor
     Certificates immediately prior to such selection. The Master Servicer, the
     Trustee and the Sellers shall promptly enter into any such successor Credit
     Enhancement Agreement, and the Master Servicer shall use its best efforts
     to secure the signature of any other required party to such agreement.

          (ii) Regardless of whether the Credit Enhancement is Funded Credit
     Enhancement, the Master Servicer may elect, at any time, to obtain a
     successor Credit Enhancement, provided that such successor Credit
     Enhancement does not cause the ratings of the Investor Certificates of the
     Series established hereby to be withdrawn or lowered by either of the
     Rating Agencies from the respective ratings of such Investor Certificates
     immediately prior to such election.

          (iii) In any case, subject to the foregoing, any successor Credit
     Enhancement obtained by the Master Servicer need not consist of the same
     type of Credit Enhancement as the Initial Credit Enhancement, but may
     consist of a different type of facility, including, but not limited to, a
     reserve account, a cash collateral account, an irrevocable standby letter
     of credit, a surety bond or a combination of any of the above. Upon



                                       49
<PAGE>   61

     issuance of, or other provision for, any such successor Credit Enhancement,
     the Trustee shall terminate the prior Credit Enhancement and Credit
     Enhancement Agreement.

     (c) Supplemental Credit Enhancement Event. Upon the occurrence of a
Supplemental Credit Enhancement Event, Discover Bank as Servicer shall, within
60 days of notice from Standard & Poor's of the withdrawal or downgrade (or such
longer period as may be agreed to by Standard & Poor's), arrange for the payment
of the Supplemental Credit Enhancement Amount, if any, by a Person other than
Discover Bank (or from Series Excess Servicing) to the Trustee as administrator
of the Credit Enhancement for application in accordance with the provisions of
the Credit Enhancement Agreement. Both the form and the provider of the
Supplemental Credit Enhancement Amount, if any, shall be determined at the time
it is to be paid; provided, that the Master Servicer shall have received
confirmation from Standard & Poor's that the arrangements with respect to the
Supplemental Credit Enhancement Amount, if any, will not result in the rating of
the Investor Certificates of the Series established hereby being withdrawn or
lowered. In addition to the foregoing, the Master Servicer shall notify Moody's
of the occurrence of a Supplemental Credit Enhancement Event as soon as
practicable after such occurrence, and shall notify Moody's in advance of its
implementation of the form and provider of the Supplemental Credit Enhancement
Amount, if any.

     SECTION 12. Alternative Credit Support Election.

     (a) The Sellers may elect to effect a change in the calculation of the
Class Percentage with respect to Finance Charge Collections during the Early
Accumulation Period or the Amortization Period, as set forth in the definition
of "Class Percentage," and increase the Available Class B Credit Enhancement
Amount, by making an Alternative Credit Support Election. An Alternative Credit
Support Election may be made as follows:

          (i) at any time during the Revolving Period, Discover Bank on behalf
     of the Holder of the Seller Certificate shall deliver written notice of
     such Alternative Credit Support Election to the Rating Agencies, the
     Trustee and the Credit Enhancement Provider;

          (ii) prior to the last day of the Revolving Period, the Additional
     Credit Support Amount shall be paid to the Trustee as administrator of the
     Credit Enhancement for application in accordance with the provisions of the
     Credit Enhancement Agreement; provided, however, that following an Early
     Accumulation Event or an Amortization Event, the Additional Credit Support
     Amount may be paid to the Trustee as administrator of the Credit
     Enhancement at any time on or prior to the last day of the Due Period in
     which the Early Accumulation Event or the Amortization Event occurs;

          (iii) prior to the last day of the Revolving Period (or, following an
     Early Accumulation Event or an Amortization Event during the Revolving
     Period, on or prior to the last day of the Due Period in which the Early
     Accumulation Event or the Amortization Event occurs), the Rating Agencies
     shall have confirmed that the



                                       50
<PAGE>   62

     Alternative Credit Support Election shall not cause a reduction in or
     withdrawal of the rating of any Class of Investor Certificates of the
     Series established hereby; and

          (iv) prior to the last day of the Revolving Period (or, following an
     Early Accumulation Event or an Amortization Event during the Revolving
     Period, on or prior to the last day of the Due Period in which the Early
     Accumulation Event or the Amortization Event occurs), Discover Bank on
     behalf of the Holder of the Seller Certificate shall have delivered to the
     Rating Agencies written confirmation that the conclusions reached in the
     legal opinions delivered on the Initial Closing Date regarding the absolute
     transfer of the Receivables and the security interest of the Trust in the
     Receivables are not affected by the Alternative Credit Support Election.

     (b) If each of the actions set forth in Section 12(a) above has been taken
or satisfied as required, the Alternative Credit Support Election shall become
effective on the last day of the Due Period in which the Additional Credit
Support Amount has been paid to the Trustee as administrator of the Credit
Enhancement (an "Effective Alternative Credit Support Election").

     (c) At any time until the Alternative Credit Support Election becomes
effective, such Alternative Credit Support Election may be cancelled upon notice
to the Rating Agencies, the Trustee and the Credit Enhancement Provider.
Thereafter, the Additional Credit Support Amount, if any, shall be returned by
the Trustee as administrator of the Credit Enhancement in accordance with the
Credit Enhancement Agreement.

     SECTION 13. Calculation of Investor Losses.

     (a) For each Distribution Date, the Master Servicer shall calculate the
Class Investor Charged-Off Amount and the Class Cumulative Investor Charged-Off
Amount with respect to each Class, in each case as of the end of the related Due
Period.

     (b) If on any Distribution Date, the Class Investor Charged-Off Amount with
respect to any Class exceeds the Class Charge-Off Reimbursement Amount with
respect to such Class, the Class Investor Interest and the Class Invested Amount
for such Class shall each be reduced by the amount of such excess (an "Investor
Charge-Off Loss" with respect to such Class).

     (c) On each Distribution Date the Class Investor Interest and the Class
Invested Amount for each Class shall be increased by, and the amount of
aggregate unreimbursed Investor Losses for each such Class shall be decreased
by, the positive difference, if any, between the Class Charge-Off Reimbursement
Amount on such Distribution Date and the Class Investor Charged-Off Amount for
such Distribution Date; provided, however, that neither the Class Invested
Amount nor the Class Investor Interest shall exceed the Class Initial Investor
Interest for such Class minus the sum of (x) the aggregate amount of payments of
Certificate Principal paid to the Investor Certificateholders of such Class
prior to such Distribution Date, (y) in the case of the Class Investor Interest,
the amount on deposit in the Series Principal Funding Account for the benefit of
such Class in respect of Certificate Principal and (z) the aggregate amount of
losses, if any, on investments of principal of funds on deposit in the Series
Principal Funding Account for



                                       51
<PAGE>   63

the benefit of such Class; and provided, further, that the amount of Investor
Losses with respect to any Class shall not be reduced to an amount less than
zero.

     SECTION 14. Servicing Compensation. As compensation for its servicing
activities hereunder and under the Pooling and Servicing Agreement and
reimbursement of its expenses as set forth in Section 3.03 of the Pooling and
Servicing Agreement, the Master Servicer shall be entitled to receive a monthly
servicing fee with respect to the Series established hereby in respect of any
Due Period (or portion thereof) prior to the earlier of the date on which the
Series Investor Interest is reduced to zero and the Series Termination Date.
Such monthly servicing fees shall be composed of the Class Monthly Servicing
Fees and the Supplemental Servicing Fees, if any. The Class Monthly Servicing
Fees shall be paid to the Master Servicer on behalf of each Class on each
Distribution Date pursuant to Section 10. The Supplemental Servicing Fee, if
any, shall be paid to the Master Servicer on or before each Distribution Date
from the Series Additional Funds for such Distribution Date. In no event shall
the Trustee or the Investor Certificateholders be liable for the Supplemental
Servicing Fee.

     SECTION 15. Class Interest Rate Caps.

     (a) In the event that the Master Servicer has obtained a Class Interest
Rate Cap in favor of the Trustee for the benefit of a Class or Subclass that
does not have a fixed or maximum Certificate Rate, the Master Servicer hereby
represents that such Class Interest Rate Cap provides that (i) the Trust shall
not be required to make any payments thereunder and (ii) the Trust shall be
entitled to receive payments (determined in accordance with the Class Interest
Rate Cap) from the Interest Rate Cap Provider on an Interest Payment Date if
LIBOR or the Commercial Paper Rate, as applicable, for the related Calculation
Period exceeds the Class Cap Rate for the applicable Class or Subclass. Any
Class Interest Rate Cap Payment shall be deposited into the Series Interest
Funding Account.

     (b) In the event that the commercial paper or certificate of deposit rating
of the Interest Rate Cap Provider is withdrawn or reduced below the ratings
specified in the Series Term Sheet (or, in either case, such lower rating as the
applicable Rating Agency shall allow), then within 30 days after receiving
notice of such decline in the creditworthiness of the Interest Rate Cap Provider
as determined by either Rating Agency, either (x) the Interest Rate Cap
Provider, with the prior confirmation of the Rating Agencies that such
arrangement will not result in the reduction or withdrawal of the rating of any
Investor Certificates of the Series established hereby, will enter into an
arrangement the purpose of which shall be to assure performance by the Interest
Rate Cap Provider of its obligations under the Class Interest Rate Caps; or (y)
the Master Servicer shall at its option either (i) with the prior confirmation
of the Rating Agencies that such action will not result in a reduction or
withdrawal of the rating of any Investor Certificates of the Series established
hereby, cause the Interest Rate Cap Provider to pledge securities in the manner
provided by applicable law, which shall be held by the Trustee or its agent free
and clear of the Lien of any third party, in a manner conferring on the Trustee
a perfected first Lien in such securities securing the Interest Rate Cap
Provider's performance of its obligations under the Class Interest Rate Caps, or

Cap Arrangements meeting the requirements of Section 15(c)

have been obtained, direct the Trustee (A) to provide written notice to the
Interest Rate Cap Provider of its intention to terminate the Class Interest Rate
Caps within such 30-day period and (B) to terminate the Class Interest Rate Caps
within such 30-day period, to request the payment to it of all amounts due to
the Trust under the Class Interest Rate Caps through the termination date and to
deposit any such amounts so received, on the day of receipt, to the Series
Interest Funding Account, or (iii) establish any other arrangement (including an
arrangement or arrangements in addition to or in substitution for any prior
arrangement made in accordance with the provisions of this Section 15(b))
satisfactory to the Rating Agencies such that the Rating Agencies will not
reduce or withdraw the rating of any Investor Certificates of the Series
established hereby (a "Qualified Substitute Cap Arrangement"); provided,
however, that in the event at any time any alternative arrangement established
pursuant to clause (x) or (y)(i) or (y)(iii) above shall cease to be
satisfactory to the Rating Agencies then the provisions of this Section 15(b)
shall again be applied and in connection therewith the 30-day period referred to
above shall commence on the date the Master Servicer receives notice of such
cessation.

     (c) Unless an alternative arrangement pursuant to clause (x) or (y)(i) of
Section 15(b) is being established, the Master Servicer shall use its best
efforts to obtain Replacement Class Interest Rate Caps or Qualified Substitute
Cap Arrangements meeting the requirements of this Section 15(c) during the
30-day period referred to in Section 15(b). The Trustee shall not terminate the
Class Interest Rate Caps unless, prior to the expiration of the 30-day period
referred to in Section 15(b), the Master Servicer delivers to the Trustee (i)
Replacement Class Interest Rate Caps or Qualified Substitute Cap Arrangements,
(ii) to the extent applicable, an Opinion of Counsel as to the due
authorization, execution and delivery and validity and enforceability of each
such Replacement Class Interest Rate Cap or Qualified Substitute Cap
Arrangement, as the case may be, and (iii) confirmation from each Rating Agency
that the termination of the Class Interest Rate Caps and their replacement with
such Replacement Class Interest Rate Caps or Qualified Substitute Cap
Arrangements will not adversely affect its rating of the Investor Certificates
of the Series established hereby.

     (d) Master Servicer shall notify the Trustee, the Rating Agencies and the
Credit Enhancement Provider within five Business Days after obtaining knowledge
that the commercial paper or certificate of deposit rating of the Interest Rate
Cap Provider has been withdrawn or reduced by either Rating Agency.

     (e) Notwithstanding the foregoing, the Master Servicer may at any time
obtain Replacement Class Interest Rate Caps, provided that the Master Servicer
delivers to the Trustee (i) an Opinion of Counsel as to the due authorization,
execution and delivery and validity and enforceability of such Replacement Class
Interest Rate Caps and (ii) confirmation from the Rating Agencies that the
termination of the then current Class Interest Rate Caps and their replacement
with such Replacement Class Interest Rate Caps will not adversely affect the
rating of the Investor Certificates of the Series established hereby.

     (f) The Trustee hereby appoints the Master Servicer to perform the duties
of the calculation agent under the Class Interest Rate Caps and the Master
Servicer accepts such appointment.

     SECTION 16. Class Interest Rate Swaps. In the event that the Investor
Certificates of any Class are subject to a Class Interest Rate Swap, the Trust
will enter into a Class Interest Rate Swap in a form approved by the Master
Servicer. Pursuant to the terms of the Class Interest Rate Swap, the Interest
Rate Swap Counterparty shall pay to the Trust the Net Swap Receipt or the Trust
shall pay to the Interest Rate Swap Counterparty the Net Swap Payment, as
applicable. If the Trust does not receive payment from the Interest Rate Swap
Counterparty on each Interest Payment Date (if due), the Trustee, on behalf of
the Trust, shall attempt to determine from the Interest Rate Swap Counterparty
the reasons therefore and whether such payment is to be made by the Interest
Rate Swap Counterparty on such Interest Payment Date. If the Class Interest Rate
Swap has not been terminated and the Trust has not received any payment due from
the Interest Rate Swap Counterparty on the related Interest Payment Date, the
Trustee shall notify the Master Servicer of such fact prior to 1:00 p.m. Chicago
time on such Interest Payment Date.

     SECTION 17. Investor Certificateholders' Monthly Statement. On each
Statement Date, a statement substantially in the form of Exhibit B prepared by
the Trustee (based on information provided by the Master Servicer) setting forth
the information listed thereon shall be available from the Trustee, each Paying
Agent and, if applicable, the Listing Agent.

     SECTION 18. Master Servicer's Monthly Certificate. On or before the second
Business Day preceding each Statement Date, the Master Servicer shall forward to
Discover Bank on behalf of the Holder of the Seller Certificate, the Trustee and
each Paying Agent a certificate of a Servicing Officer substantially in the form
of Exhibit C setting forth the information listed thereon.

     SECTION 19. Notices. Any notices to holders of Investor Certificates issued
in bearer form shall be given as described in the Series Term Sheet.

     SECTION 20. Additional Amortization Events. If any one of the following
events shall occur:

     (a) after giving effect to payments and distributions on the Class Expected
Final Payment Date or the Class Final Maturity Date, as applicable, with respect
to any Class, the Class Invested Amount for such Class is not reduced to zero;

     (b) if applicable, following either (i) the withdrawal or reduction of the
commercial paper or certificate of deposit rating of any Interest Rate Cap
Provider to below the ratings specified in the Series Term Sheet (or, in either
case, such lower rating as the applicable Rating Agency has allowed) or (ii)
notice from either Rating Agency that any Qualified Substitute Cap Arrangement
or any other arrangement established pursuant to Section 15 is no longer
satisfactory to such Rating Agency, the Master Servicer shall fail, within the
applicable time period specified in Section 15, to (x) obtain Replacement Class
Interest Rate Caps or Qualified Substitute Cap Arrangements or (y) cause the
Interest Rate Cap Provider to pledge securities as collateral securing the
obligations of the Interest Rate Cap Provider or establish any other arrangement
as provided in Section 15, in each case in a manner satisfactory to the Trustee
and


                                       54
<PAGE>   66


the Rating Agencies (such that neither Rating Agency will reduce or withdraw the
ratings of the Investor Certificates of the Series established hereby); or

     (c) if the amount of Principal Receivables in the Trust at the end of any
Due Period for three consecutive Due Periods of the Early Accumulation Period
shall be less than the Minimum Principal Receivables Balance and Discover Bank
shall have failed to assign Receivables in Additional Accounts or Participation
Interests to the Trust in at least the amount of the deficiency by the tenth day
of the calendar month of the following Due Period;

an Amortization Event shall occur with respect to the Investor Certificates of
the Series established hereby, immediately upon the occurrence of such event. If
an Amortization Event described in this Section 20 shall occur, this Section 20
constitutes written notice by the Trustee and not less than 51% of the Class
Invested Amount of each Class of the Series established hereby to the Master
Servicer and the Sellers that such Amortization Event has occurred. No
additional notice of any kind, which is hereby waived by the Sellers and the
Master Servicer, shall be required as a condition of the occurrence of any
Amortization Event described in this Section 20. In addition, the events set
forth in Section 21 shall constitute either Early Accumulation Events or
additional Amortization Events with respect to the Series established hereby .

     SECTION 21. Early Accumulation Events; Additional Amortization Events. If
the Series established hereby is eligible to have an Early Accumulation Period,
each of the events described in clause (a), (b), (g), (i) or (j) of Section 9.01
of the Pooling and Servicing Agreement shall not be Amortization Events but
shall instead be Early Accumulation Events. In addition, for purposes of this
Series Supplement, each of the following events shall be (i) Early Accumulation
Events, if the Series established hereby is eligible to have an Early
Accumulation Period, or (ii) Amortization Events, if the Series established
hereby is not eligible to have an Early Accumulation Period:

     (a) on any Distribution Date, the three month rolling average Series Excess
Spread is less than the Series Buffer Amount and the three month rolling average
Group Excess Spread is less than the Group Buffer Amount;

     (b) if a Supplemental Credit Enhancement Event shall have occurred and
Discover Bank as Servicer shall have failed to arrange for the Supplemental
Credit Enhancement in accordance with the requirements of Section 11(c) hereof
(including, without limitation, receipt of the confirmation from Standard &
Poor's required thereby).

If any event described in clause (a), (b), (g), (i) or (j) of Section 9.01 of
the Pooling and Servicing Agreement occurs, an Early Accumulation Event shall
occur with respect to the Investor Certificates of such Class only if the event
has a material adverse effect on the Investor Certificateholders of such Class
and if, after the applicable grace period described in those clauses, either the
Trustee declares or the Investor Certificateholders of such Class evidencing
Fractional Undivided Interests aggregating not less than 51% of the Class
Invested Amount for either Class declare by written notice to Discover Bank and
the Master Servicer (and to the



                                       55
<PAGE>   67

Trustee if given by the Investor Certificateholders) that an Early Accumulation
Event has occurred as of the date of the notice. In the case of any event
described in clause (a) or (b) of this Section 21, an Early Accumulation Event
shall occur with respect to the Investor Certificates of such Class immediately
upon the occurrence of the event without any notice or other action on the part
of the Trustee or the Investor Certificateholders of such Class. On the date on
which an Early Accumulation Event is deemed to have occurred the Early
Accumulation Period will commence.

     SECTION 22. Purchase of Investor Certificates and Series Termination.

     (a) If as of any Distribution Date during the Amortization Period (after
giving effect to any payments calculated pursuant to Section 9 made on such
Distribution Date) the Series Investor Interest of the Series established hereby
is less than or equal to 5% of the Series Initial Investor Interest, Discover
Bank on behalf of the Holder of the Seller Certificate may purchase and cancel
the Investor Certificates of the Series established hereby by depositing into
the Series Distribution Account, on the immediately succeeding Distribution
Date, an amount equal to the Series Investor Interest as of the last day of the
Due Period related to such immediately succeeding Distribution Date. The Master
Servicer shall direct the Trustee in writing to withdraw the amount allocable to
such Class from the Series Distribution Account and pay such amount to the
Investor Certificateholders of such Class pursuant to Section 12.02 of the
Pooling and Servicing Agreement. All Investor Certificates of the Series
established hereby that are purchased by Discover Bank on behalf of the Holder
of the Seller Certificate pursuant to this Section 22(a) shall be delivered by
Discover Bank on behalf of the Holder of the Seller Certificate upon such
purchase to, and be cancelled by, the Transfer Agent and be disposed of in a
manner satisfactory to the Trustee and Discover Bank on behalf of the Holder of
the Seller Certificate.

     (b) If as of any Distribution Date during the Accumulation Period, the
Early Accumulation Period or the Controlled Liquidation Period, as applicable
(after giving effect to any payments calculated pursuant to Section 9 made on
such Distribution Date), the Series Investor Interest of the Series established
hereby is less than or equal to 5% of the Series Initial Investor Interest
(before giving effect to any reduction in the Series Initial Investor Interest
pursuant to Section 6.14 of the Pooling and Servicing Agreement), Discover Bank
on behalf of the Holder of the Seller Certificate may, but shall not be
obligated to, purchase the Investor Certificates of the Series established
hereby by depositing into the Series Principal Funding Account, on such
Distribution Date, an amount equal to such Series Investor Interest. After
giving effect to such deposit, such Series Investor Interest shall be reduced to
zero, and the Seller Interest shall be increased by the amount of such deposit.

     (c) Following the sale of Receivables pursuant to Section 12.02 of the
Pooling and Servicing Agreement, the Master Servicer shall direct the Trustee in
writing to withdraw the amount allocable to each Class from the Series
Distribution Account and pay such amount to the Investor Certificateholders of
such Class pursuant to Section 12.02 of the Pooling and Servicing Agreement.



                                       56
<PAGE>   68

     SECTION 23. Variable Accumulation Period. If the Series Term Sheet for the
Series established hereby so provides, the Master Servicer may elect, by written
notice to the Trustee, Discover Bank on behalf of the Holder of the Seller
Certificate and the Credit Enhancement Provider, to delay the commencement of
the Accumulation Period, and extend the length of the Revolving Period, subject
to the conditions set forth in this Section 23; provided, however, that the
Accumulation Period shall commence no later than the first day of the Due Period
related to the Class A Expected Final Payment Date. Any such election by the
Master Servicer shall be made no later than the first day of the last scheduled
Due Period of the Revolving Period (including any prior extension of the
Revolving Period pursuant to this Section 23).

     The Master Servicer may make such election only if the following conditions
are satisfied: (i) the Master Servicer shall have delivered to the Trustee a
certificate to the effect that the Master Servicer reasonably believes that the
delay in the commencement of the Accumulation Period would not result in the
Class Invested Amount with respect to any Class of the Series established hereby
not being paid in full on the relevant Class Expected Final Payment Date; (ii)
the Rating Agencies shall have advised the Master Servicer and Discover Bank on
behalf of the Holder of the Seller Certificate that such election to delay the
commencement of the Accumulation Period would not cause the rating of any Class
of any Series then outstanding to be lowered or withdrawn; and (iii) the amount
to be deposited in the Series Principal Funding Account in respect of the
Accumulation Amount shall have been adjusted.

     SECTION 24. Optional Accumulation Period Commencement. If the Series Term
Sheet for the Series established hereby so provides, unless the Amortization
Period or the Early Accumulation Period shall have commenced prior thereto, the
Master Servicer may elect to commence the Accumulation Period by delivering
written notice to the Trustee, Discover Bank, on behalf of the Holder of the
Seller Certificate and the Credit Enhancement Provider at least 5 Business Days
prior to the Accumulation Commencement Date subject to the conditions set forth
in this Section 24; provided, however, that the Accumulation Period shall
commence no later than the first day of the following Due Period. Such written
notice shall set forth the Accumulation Amount for each Distribution Date
relating to the Accumulation Period.

     SECTION 25. Series Yield Factor. The Series Yield Factor for the Series
established hereby shall initially be the Series Yield Factor set forth in the
Series Term Sheet. The Master Servicer may change the Series Yield Factor upon
20 days prior written notice to the Trustee, Discover Bank on behalf of the
Holder of the Seller Certificate, the Credit Enhancement Provider and the Rating
Agencies, provided that the following conditions are satisfied: (i) the Series
Yield Factor may not be reduced below the initial Series Yield Factor or
increased to more than a total of 0.05; (ii) the Master Servicer shall have
delivered to the Trustee a certificate to the effect that the Master Servicer
reasonably believes that the change in the Series Yield Factor would not (x)
result in any delay in the payment of principal to the Investor
Certificateholders of any Series then outstanding, or (y) cause an Amortization
Event or an Early Accumulation Event to occur with respect to any Series then
outstanding; and (iii) Standard & Poor's shall have advised the Master Servicer
and Discover Bank on behalf of the Holder of the Seller Certificate that such
change in the Series Yield Factor would not cause the rating of any Class of any
Series then


                                       57
<PAGE>   69

outstanding to be lowered or withdrawn. Any such change shall be effective as of
the first day of the Due Period specified in the notice of the Master Servicer.

     SECTION 26. Ratification of Pooling and Servicing Agreement. As
supplemented and amended by this Series Supplement, the Pooling and Servicing
Agreement is in all respects ratified and confirmed and the Pooling and
Servicing Agreement as so supplemented by this Series Supplement shall be read,
taken, and construed as one and the same instrument.

     SECTION 27. Counterparts. This Series Supplement may be executed in any
number of counterparts, each of which so executed shall be deemed to be an
original, but all of such counterparts shall together constitute but one and the
same instrument.

     SECTION 28. Governing Law. This Series Supplement shall be construed in
accordance with the internal 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.

     SECTION 29. Intention of Parties. The parties intend the sale, transfer,
assignment or conveyance of Receivables in connection herewith to be a sale of
financial assets in connection with a securitization, an absolute transfer for
all purposes (other than for federal, state and local income and franchise tax
purposes) and to be treated as a sale for accounting purposes.

     SECTION 30. Amendment for Sale Accounting Purposes. If any Seller
determines that (i) an amendment to this Agreement or the Pooling and Servicing
Agreement is necessary or desirable for such Seller to maintain or establish
sale accounting treatment under then-applicable financial accounting standards,
and (ii) such Seller cannot enter into such amendment pursuant to Section 13.01
of the Pooling and Servicing Agreement without obtaining the consent of a
specified percentage of Investor Certificateholders, then the Master Servicer,
the Sellers, the Trustee and the Servicers may nonetheless enter into such
amendment without obtaining the consent of any Certificateholder of any Investor
Certificates of this Series so long as the Trustee shall have been advised by
the Rating Agencies that such amendment will not result in the downgrading or
withdrawal of the rating assigned to any Class of any Series then outstanding.

     Any such amendment may include, without limitation, any changes necessary
to convert the Trust from a "one-tier" securitization structure to a "two-tier"
securitization structure. Notwithstanding the foregoing, any Investor
Certificateholder that acquires an Investor Certificate of this Series will be
deemed to have consented to any such amendment for all purposes, including for
purposes of calculating whether the requisite consent percentage, if any, under
Section 13.01 of the Pooling and Servicing Agreement has been received for any
amendment that requires such consent because of the lack of provisions
comparable to this Section 30 in the Series Supplements for other Series then
outstanding (except that Investor Certificates beneficially owned by any Seller
or any affiliate or agent of any Seller will not be included in any such
calculation).

                [FORM OF THE REVERSE OF THE CLASS A CERTIFICATES]

     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 be evidence of indebtedness of the Sellers. The
Sellers and the Class A Certificateholder, by the acceptance of this Class A
Certificate, agree to treat this Class A Certificate for federal, state and
local income and franchise tax purposes as indebtedness of the Sellers secured
by the Receivables and other assets held in the Trust.

     To the extent not defined herein, the capitalized terms used herein have
the meanings assigned in the Pooling and Servicing Agreement or the Series
Supplement. This Class A Certificate is issued under and is subject to the
terms, provisions and conditions of the Pooling and Servicing Agreement and the
Series Supplement, to which Pooling and Servicing Agreement and Series
Supplement, as each may be amended from time to time, the Class A
Certificateholder by virtue of the acceptance hereof assents and by which the
Class A Certificateholder is bound.

     This Class A Certificate is one of a series of Certificates entitled
"Discover Card Master Trust I, Series 2001-6 5.75% Class A Credit Card
Pass-Through Certificates" (the "Class A Certificates"), each of which
represents a Fractional Undivided Interest in the Trust including the right to
receive the Collections and other amounts at the times and in the amounts
specified in the Pooling and Servicing Agreement and the Series Supplement to be
deposited in the Investor Accounts with respect to Discover Card Master Trust I,
Series 2001-6 or paid to the Class A Certificateholders. Also issued under the
Pooling and Servicing Agreement and the Series Supplement are Investor
Certificates designated as "Discover Card Master Trust I, Series 2001-6 Floating
Rate Class B Credit Card Pass-Through Certificates" (the "Class B
Certificates"). The Class A Certificates and the Class B Certificates are
collectively referred to herein as the Investor Certificates.

     The aggregate interest represented by the Class A Certificates at any time
in the assets of the Trust shall not exceed an amount equal to the Class A
Investor Interest at such time, plus accrued but unpaid Certificate Interest for
the Class A Certificates and any interest thereon. The Class Initial Investor
Interest of the Class A Certificates is $500,000,000. The Class A Invested
Amount on any Distribution Date will be an amount equal to the Class A Initial
Investor Interest minus the sum of (a) the aggregate amount of payments of
Certificate Principal paid to the Class A Certificateholders prior to such
Distribution Date, (b) the aggregate amount of Investor Losses for such Class
not reimbursed prior to such Distribution Date and (c) the aggregate amount of
losses of principal on investments in funds on deposit for the benefit of such
Class in the Series Principal Funding Account. In addition to the Investor
Certificates, a Seller Certificate has been issued pursuant to the Pooling and
Servicing Agreement which represents, at any time, the undivided interest in the
Trust not represented by the Investor Certificates or the investor certificates
of any other Series of investor certificates then outstanding. Subject to the
terms and conditions of the Pooling and Servicing 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 the Trust.


                                     A-1-4

     During the Revolving Period, which begins on the Series Cut-Off Date, and
during the Accumulation Period, Certificate Interest will be distributed on the
15th day of each June and December with respect to interest accrued during the
preceding Interest Accrual Period, commencing in December 2001, or if such 15th
day is not a Business Day, on the next succeeding Business Day (an "Interest
Payment Date"), to the Class A Certificateholders of record as of the last day
of the month preceding the related Interest Payment Date. Principal on the Class
A Certificates is scheduled to be paid in a single payment on the Distribution
Date in June 2006 (the "Class A Expected Final Payment Date"), but may be paid
sooner or later and in installments if an Amortization Event occurs. During the
Amortization Period, if any, Certificate Interest and Certificate Principal
collected by the Master Servicer will be distributed to the Class A
Certificateholders on the Distribution Date of each calendar month, commencing
in the month following the commencement of the Amortization Period. In any
event, the final payment of principal of either class will be made no later than
the first Business Day following the Distribution Date in December 2008 (the
"Series Termination Date").

     The amount to be distributed on each Principal Payment Date to the holder
of this Class A Certificate will be equal to the product of (a) the percentage
equivalent of a fraction, the numerator of which is the portion of the Class A
Initial Investor Interest evidenced by this Class A Certificate and the
denominator of which is the Class A Initial Investor Interest and (b) the
aggregate of all payments to be made to the Class A Certificateholders on such
Distribution Date. 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 (except for
the final distribution in respect of this Class A Certificate) without the
presentation or surrender of this Class A Certificate or the making of any
notation thereon, except that with respect to Class A Certificates registered in
the name of Cede & Co., the nominee registrant for The Depository Trust Company,
distributions will be made in the form of immediately available funds.

     This Class A Certificate does not represent an obligation of, or an
interest in, the Master Servicer. This Class A Certificate is limited in right
of payment to certain Collections respecting the Receivables, all as more
specifically set forth hereinabove and in the Pooling and Servicing Agreement
and the Series Supplement.

     The Pooling and Servicing Agreement permits, with certain exceptions, the
amendment and modification of the rights and obligations of the Master Servicer,
and the rights of Investor Certificateholders under the Pooling and Servicing
Agreement and Series Supplement, at any time by the Master Servicer, the Sellers
and the Trustee in certain cases (some of which require confirmation from the
Rating Agencies that such amendment will not result in the downgrading or
withdrawal of the rating assigned to the Investor Certificates) without the
consent of the Investor Certificateholders, and in all other cases with the
consent of the Investor Certificateholders owning Fractional Undivided Interests
aggregating not less than 66-2/3% of the Class Invested Amount of each such
affected Class (and with confirmation from the Rating Agencies that such
amendment will not result in the downgrading or withdrawal of the rating
assigned to the Investor Certificates); provided, however, that no such
amendment shall (a) have a material adverse effect on any Class of Investor
Certificateholders by reducing in any manner the amount of, or delaying the
timing of, distributions which are required to be made on any

Investor Certificate without the consent of the affected Investor
Certificateholders or (b) reduce the aforesaid percentage required to consent to
any such amendment, without the consent of each Investor Certificateholder of
each affected Class then of record; and provided, further, that the permitted
activities of the Trust may be significantly changed only with the consent of
the Holders of Investor Certificates evidencing Fractional Undivided Interests
aggregating not less than 51% of the Aggregate Invested Amount. Any such
amendment and any such consent by the Class A Certificateholder, including the
deemed consent described in the following sentence, shall be conclusive and
binding on such Class A Certificateholder and upon all future Holders of this
Class A Certificate and of any Class A Certificate issued in exchange hereof or
in lieu hereof whether or not notation thereof is made upon this Class A
Certificate. The Class A Certificateholder, by acceptance of this Class A
Certificate, will be deemed to have consented for all purposes to any amendment
that any Seller determines is necessary or desirable for such Seller to maintain
or establish sale accounting treatment under then-applicable financial
accounting standards.

     The transfer of this Class A Certificate shall be registered in the
Certificate Register upon surrender of this Investor 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 and the Transfer Agent and Registrar duly executed
by the Class A Certificateholder or such Class A Certificateholder's attorney
duly authorized in writing, 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 Pooling and Servicing 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
Master 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 Master Servicer, the Trustee, the Paying Agent and the Transfer Agent,
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
Master Servicer, the Trust nor the Trustee, the Paying Agent, the Transfer
Agent, nor any agent of any of them or any such agent shall be affected by
notice to the contrary except in certain circumstances described in the Pooling
and Servicing Agreement.

     Subject to certain conditions in the Pooling and Servicing Agreement and
the Series Supplement, if the principal of the Investor Certificates has not
been paid in full prior to the Series Termination Date, the obligations created
by the Pooling and Servicing Agreement and the Series Supplement with respect to
the Investor Certificates shall terminate on the Series Termination Date.

                                       By:

                [FORM OF THE REVERSE OF THE CLASS B CERTIFICATES]

     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 be evidence of indebtedness of the Sellers. The
Sellers and the Class B Certificateholder, by the acceptance of this Class B
Certificate, agree to treat this Class B Certificate for federal, state and
local income and franchise tax purposes as indebtedness of the Sellers secured
by the Receivables and other assets held in the Trust.

     To the extent not defined herein, the capitalized terms used herein have
the meanings assigned in the Pooling and Servicing Agreement or the Series
Supplement. This Class B Certificate is issued under and is subject to the
terms, provisions and conditions of the Pooling and Servicing Agreement and the
Series Supplement, to which Pooling and Servicing Agreement and Series
Supplement, as each may be amended from time to time, the Class B
Certificateholder by virtue of the acceptance hereof assents and by which the
Class B Certificateholder is bound.

     This Class B Certificate is one of a series of Certificates entitled
"Discover Card Master Trust I, Series 2001-6 Floating Rate Class B Credit Card
Pass-Through Certificates" (the "Class B Certificates"), each of which
represents a Fractional Undivided Interest in the Trust including the right to
receive the Collections and other amounts at the times and in the amounts
specified in the Pooling and Servicing Agreement and the Series Supplement to be
deposited in the Investor Accounts with respect to Discover Card Master Trust I,
Series 2001-6 or paid to the Class B Certificateholders. Also issued under the
Pooling and Servicing Agreement and the Series Supplement are Investor
Certificates designated as "Discover Card Master Trust I, Series 2001-6 5.75%
Class A Credit Card Pass-Through Certificates" (the "Class A Certificates"). The
Class A Certificates and the Class B Certificates are collectively referred to
herein as the Investor Certificates.

     The aggregate interest represented by the Class B Certificates at any time
in the assets of the Trust shall not exceed an amount equal to the Class
Investor Interest of the Class B Certificates at such time, plus accrued but
unpaid Certificate Interest for the Class B Certificates and any interest
thereon. The Class B Certificateholders are also entitled to the benefit of the
Credit Enhancement, to the extent provided in the Series Supplement. The Class
Initial Investor Interest of the Class B Certificates is $26,316,000. The Class
B Invested Amount on any Distribution Date will be an amount equal to the Class
B Initial Investor Interest minus the sum of (a) the aggregate amount of
payments of Certificate Principal paid to the Class B Certificateholders prior
to such Distribution Date, (b) the aggregate amount of Investor Losses for such
Class not reimbursed prior to such Distribution Date and (c) the aggregate
amount of losses of principal on investments in funds on deposit for the benefit
of such Class in the Series Principal Funding Account. In addition to the
Investor Certificates, a Seller Certificate has been issued pursuant to the
Pooling and Servicing Agreement which represents, at any time, the undivided
interest in the Trust not represented by the Investor Certificates or the
investor certificates of any other Series of investor certificates then
outstanding. Subject to the terms and conditions of the Pooling and Servicing
Agreement, the Sellers may from time to time direct the


                                     A-2-4
<PAGE>   81

Trustee, on behalf of the Trust, to issue one or more new Series of investor
certificates, which will represent Fractional Undivided Interests in the Trust.

     During the Revolving Period, which begins on the Series Cut-Off Date, and
during the Accumulation Period, Certificate Interest will be distributed on the
15th day of each calendar month with respect to interest accrued during the
preceding Interest Accrual Period, commencing in August 2001, or if such 15th
day is not a Business Day, on the next succeeding Business Day (each, an
"Interest Payment Date"), to the Class B Certificateholders of record as of the
last day of the month preceding the related Interest Payment Date. Principal on
the Class B Certificates is scheduled to be paid in a single payment on the
Distribution Date in July 2006 (the "Class B Expected Final Payment Date"), but
may be paid sooner or later or in installments under certain circumstances.
During the Amortization Period, if any, Certificate Interest and Certificate
Principal collected by the Master Servicer will be distributed to the Class B
Certificateholders on the Distribution Date of each calendar month, commencing
in the month following the commencement of the Amortization Period; provided,
however, that no Certificate Principal will be distributed to the Class B
Certificateholders until the Class A Investor Interest has been reduced to zero.
The rights of the Class B Certificateholders to receive the distributions to
which they would otherwise be entitled on the Receivables will be subordinated
to the rights of the Class A Certificateholders and the Master Servicer to the
extent described in the Pooling and Servicing Agreement and Series Supplement.
In any event, the final payment of principal of either Class will be made no
later than the first Business Day following the Distribution Date in December
2008 (the "Series Termination Date").

     The amount to be distributed on each Distribution Date to the holder of
this Class B Certificate will be equal to the product of (a) the percentage
equivalent of a fraction, the numerator of which is the portion of the Class B
Initial Investor Interest evidenced by this Class B Certificate and the
denominator of which is the Class B Initial Investor Interest and (b) the
aggregate of all payments to be made to the Class B Certificateholders on such
Distribution Date. Distributions with respect to this Class B Certificate will
be made by the Paying Agent by check mailed to the address of the Class B
Certificateholder of record appearing in the Certificate Register (except for
the final distribution in respect of this Class B Certificate) without the
presentation or surrender of this Class B Certificate or the making of any
notation thereon, except that with respect to Class B Certificates registered in
the name of Cede & Co., the nominee registrant for The Depository Trust Company,
distributions will be made in the form of immediately available funds.

     This Class B Certificate does not represent an obligation of, or an
interest in, the Master Servicer. This Class B Certificate is limited in right
of payment to certain Collections respecting the Receivables, all as more
specifically set forth hereinabove and in the Pooling and Servicing Agreement
and the Series Supplement.

     The Pooling and Servicing Agreement permits, with certain exceptions, the
amendment and modification of the rights and obligations of the Master Servicer,
and the rights of Investor Certificateholders under the Pooling and Servicing
Agreement and Series Supplement, at any time by the Master Servicer, the Sellers
and the Trustee in certain cases (some of which require


                                     A-2-5
<PAGE>   82

confirmation from the Rating Agencies that such amendment will not result in the
downgrading or withdrawal of the rating assigned to the Investor Certificates)
without the consent of the Investor Certificateholders, and in all other cases
with the consent of the Investor Certificateholders owning Fractional Undivided
Interests aggregating not less than 66-2/3% of the Class Invested Amount of each
such affected Class (and with confirmation from the Rating Agencies that such
amendment will not result in the downgrading or withdrawal of the rating
assigned to the Investor Certificates); provided, however, that no such
amendment shall (a) have a material adverse effect on any Class of Investor
Certificateholders by reducing in any manner the amount of, or delaying the
timing of, distributions which are required to be made on any Investor
Certificate without the consent of the affected Investor Certificateholders or
(b) reduce the aforesaid percentage required to consent to any such amendment,
without the consent of each Investor Certificateholder of each affected Class
then of record; and, provided, further, that the permitted activities of the
Trust may be significantly changed only with the consent of the Holders of
Investor Certificates evidencing Fractional Undivided Interests aggregating not
less than 51% of the Aggregate Invested Amount. Any such amendment and any such
consent by the Class B Certificateholder, including the deemed consent described
in the following sentence, shall be conclusive and binding on such Class B
Certificateholder and upon all future Holders of this Class B Certificate and of
any Class B Certificate issued in exchange hereof or in lieu hereof whether or
not notation thereof is made upon this Class B Certificate. The Class B
Certificateholder, by acceptance of this Class B Certificate, will be deemed to
have consented for all purposes to any amendment that any Seller determines is
necessary or desirable for such Seller to maintain or establish sale accounting
treatment under then-applicable financial accounting standards.

     The transfer of this Class B Certificate shall be registered in the
Certificate Register upon surrender of this Investor 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 and the Transfer Agent and Registrar duly executed
by the Class B Certificateholder or such Class B Certificateholder's attorney
duly authorized in writing, 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.

     The transfer of this Investor Certificate is subject to certain
restrictions set forth in the Pooling and Servicing Agreement. In no event shall
this Investor Certificate, or any interest therein, be transferred to an
employee benefit plan, trust or account subject to the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), or described in Section
4975(e)(1) of the Internal Revenue Code of 1986, as amended (the "Code"), and
not excepted under Section 4975(g). Any Holder of this Investor Certificate, by
its acceptance hereof, shall be deemed to represent and warrant that it is not
(i) an employee benefit plan (as defined in Section 3(3) of ERISA), that is
subject to Title I of ERISA, (ii) a plan described in Section 4975(e)(l) of the
Code, and not excepted under Section 4975(g), or (iii) an entity using assets to
purchase such Certificates which constitute plan assets by reason of a plan's
investment in such Holder.

     As provided in the Pooling and Servicing 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
Master 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 Master Servicer, the Trustee, the Paying Agent and the Transfer Agent,
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
Master Servicer, the Trust nor the Trustee, the Paying Agent, the Transfer
Agent, nor any agent of any of them or any such agent shall be affected by
notice to the contrary except in certain circumstances described in the Pooling
and Servicing Agreement.

     Subject to certain conditions in the Pooling and Servicing Agreement and
the Series Supplement, if the principal of the Investor Certificates has not
been paid in full prior to the Series Termination Date, the obligations created
by the Pooling and Servicing Agreement and the Series Supplement with respect to
the Investor Certificates shall terminate on the Series Termination Date.
