                                  SERVICING FEE

     SECTION 3.01 Servicing Compensation. The monthly servicing fee (the
"Monthly Servicing Fee") shall be payable to the Servicer, in arrears, on each
Distribution Date in respect of a Due Period (or portion thereof) occurring
prior to the earlier of the first Distribution Date following the Series
Termination Date and the first Distribution Date on which the Invested Amount is
zero, in an amount equal to one-twelfth of the result of (a) 1% multiplied by
(b) the aggregate principal amount of Dealer Notes outstanding as of the last
day of such Due Period and multiplied by (c) the Series 2000-1 Allocation
Percentage with respect to such Due Period. The share of the Monthly Servicing
Fee allocable to the Series 2000-1 Certificateholders with respect to any
Transfer Date (the "Investor Servicing Fee") shall be equal to the product of
(a) the Monthly Servicing Fee and (b) the Floating Allocation Percentage with
respect to such Due Period. The remainder of the Monthly Servicing Fee shall be
paid by the Seller and in no event shall the Master Trust, the Master Trust
Trustee or the Series 2000-1 Certificateholders be liable for the share of the
Monthly Servicing Fee to be paid by the Seller; and the remainder of the
Servicing Fee shall be paid by the Seller and the Investor Certificateholders of
other Series and the Series 2000-1 Certificateholders shall in no event be
liable for the share of the Servicing Fee to be paid by the Seller or the
Investor Certificateholders of other Series. The Investor Servicing Fee shall be
payable to the Servicer solely to the extent amounts are available for
distribution in accordance with the terms of this Series Supplement.

     The Servicer will be permitted, in its sole discretion, to waive the
Monthly Servicing Fee for any Distribution Date by notice to the Master Trust
Trustee on or before the related Determination Date; provided, however, that the
Servicer believes that sufficient Series Allocable Finance Charge Collections
will be available on any future Distribution Date to pay the Investor Servicing
Fee relating to the waived Monthly Servicing Fee. If the Servicer so waives the
Monthly Servicing Fee for any Distribution Date, the Monthly Servicing Fee and
the Investor Servicing Fee for such Distribution Date shall be deemed to be zero
for all purposes of this Series Supplement and the Agreement; provided, however,
that such Investor Servicing Fee shall be paid on a future date solely to the
extent amounts are available therefor pursuant to Section 4.04(a)(viii); and
provided

                                       15

<PAGE>   19
further that, to the extent any such waived Investor Servicing Fee is so paid,
the related portion of the Monthly Servicing Fee to be paid by the Seller shall
be paid by the Seller to the Servicer.

     SECTION 4.01 Rights of the Series 2000-1 Certificateholders. The Series
2000-1 Certificates shall represent fractional undivided interests in the Master
Trust, consisting of the right to receive, to the extent necessary to make the
required payments with respect to the Series 2000-1 Certificates at the times
and in the amounts and priorities specified in this Series Supplement,
Collections allocated to Series 2000-1 pursuant to Article IV of the Agreement
and this Article IV, funds on deposit in the Collections Account and the Excess

Article IV of the Agreement and this Article IV, and funds on deposit in the
Series 2000-1 Accounts (collectively, the "Series 2000-1 Certificateholders'
Interest"), it being understood that the Series 2000-1 Certificates shall not
represent any interest in any Series Account or Enhancement for the benefit of
any other Series or Class. The Servicer shall apply, or instruct the Master
Trust Trustee to apply, all funds on deposit in the Collections Account and
Excess Funding Account allocable to the Series 2000-1 Certificates, and all
funds on deposit in the Series Principal Account, the Spread Account and the
Distribution Account maintained for the Series 2000-1 Certificateholders, as

     SECTION 4.02 Establishment of Series Principal Account, Spread Account and
Liquidity Reserve Account.

         (a) Series Principal Account.

            (i) On or prior to the commencement of an Early Amortization Period
     or the Accumulation Period, the Master Trust Trustee, for the benefit of
     the Series 2000-1 Certificateholders, shall establish and maintain in the
     name of the Master Trust an Eligible Deposit Account bearing a designation
     clearly indicating that the funds deposited therein are held for the
     benefit of the Series 2000-1 Certificateholders (the "Series Principal
     Account"). The Master Trust Trustee shall possess all right, title and
     interest in all funds on deposit from time to time in the Series Principal
     Account and in all proceeds thereof. Pursuant to authority granted to it
     pursuant to Section 3.01(b) of the Agreement, the Servicer shall have the
     revocable power to instruct the Master Trust Trustee to withdraw funds from
     the Series Principal Account for the purpose of carrying out the duties of
     the Servicer under this Series Supplement and the Agreement. The Servicer
     at all times shall maintain accurate records reflecting each transaction in
     the Series Principal Account.

            (ii) Funds on deposit in the Series Principal Account overnight or
     for a longer period shall at all times be invested in Eligible Investments
     at the direction of the Servicer or its agent, subject to the restrictions
     set forth in the Agreement and subject to the requirement that each such
     Eligible Investment shall have a stated maturity on or prior to the
     following Transfer Date (or such longer maturity as shall be allowed upon
     satisfaction of the Series 2000-1 Rating Agency Condition). Net interest
     and earnings (less investment

                                       16
<PAGE>   20

     expenses) on funds on deposit in the Series Principal Account, if any,
     shall be allocated and distributed as provided in Section 4.04(a).

         (b) Spread Account.

            (i) On or prior to the Closing Date, the Master Trust Trustee, for
     the benefit of the Series 2000-1 Certificateholders, shall cause to be
     established and maintained in the name of the Master Trust, an Eligible
     Deposit Account bearing a designation clearly indicating that the funds
     deposited therein are held for the benefit of the Series 2000-1
     Certificateholders (the "Spread Account"). The Master Trust Trustee shall
     possess all right, title and interest in all funds on deposit from time to
     time in the Spread Account and in all proceeds thereof. Pursuant to
     authority granted to it pursuant to Section 3.01(b) of the Agreement, the
     Servicer shall have the revocable power to instruct the Master Trust
     Trustee to withdraw funds from the Spread Account for the purpose of
     carrying out the duties of the Servicer under this Series Supplement and
     the Agreement. The Servicer at all times shall maintain accurate records
     reflecting each transaction in the Spread Account. On the Closing Date, the
     Seller shall deposit into the Spread Account an amount equal to the Initial
     Spread Account Required Amount.

            (ii) Funds on deposit in the Spread Account overnight or for a
     longer period shall at all times be invested in Eligible Investments at the
     direction of the Servicer or its agent, subject to the restrictions set
     forth in the Agreement and subject to the requirement that each such
     Eligible Investment shall have a stated maturity on or prior to the
     following Transfer Date. Net interest and earnings (less investment
     expenses) on funds on deposit in the Spread Account, if any, shall be
     allocated and distributed as provided in Section 4.04.

            (iii) On any Transfer Date on which the amount of funds on deposit
     in the Spread Account is greater than the Projected Spread on such Transfer
     Date, the Servicer shall withdraw the amount of such excess from the Spread
     Account and allocate and pay such excess to the Seller.

            (iv) Upon the commencement of and during an Early Amortization
     Period, the Master Trust Trustee will deposit all funds in the Spread
     Account into the Liquidity Reserve Account, and no additional funds shall
     be deposited into the Spread Account.

         (c) Liquidity Reserve Account.

            (i) The Master Trust Trustee, for the benefit of the Seller, shall
     establish on or prior to the commencement of an Early Amortization Period
     and maintain or cause to be established and maintained in the name of the
     Master Trust Trustee, an Eligible Deposit Account bearing a designation
     clearly indicating that the funds deposited therein are held for the
     benefit of the Seller (the "Liquidity Reserve Account"). The Seller shall
     possess all right, title and interest in all funds on deposit from time to
     time in the Liquidity Reserve Account and in all proceeds thereof;
     provided, however, that no funds on deposit in the Liquidity Reserve
     Account shall be paid to the Seller if such payment would reduce the funds
     in such account below an amount equal to the Available Subordinated Amount.
     Pursuant to authority

                                       17
<PAGE>   21

     granted to it pursuant to Section 3.01(b) of the Agreement, the Servicer
     shall have the revocable power to instruct the Master Trust Trustee to
     withdraw funds from the Liquidity Reserve Account for the purpose of
     fulfilling the obligations of the Seller under this Series Supplement and
     the Agreement. The Servicer at all times shall maintain accurate records
     reflecting transactions in the Liquidity Reserve Account.

            (ii) Funds on deposit in the Liquidity Reserve Account overnight or
     for a longer period shall at all times be invested in Eligible Investments
     at the direction of the Seller or its agent, subject to the restrictions
     set forth in the Agreement. Any Eligible Investment with a stated maturity
     shall mature on or prior to the following Transfer Date. All net interest
     and earnings (less investment expenses) on funds on deposit in the
     Liquidity Reserve Account, if any, shall be paid to the Seller. On any
     Transfer Date on which the amount on deposit in the Liquidity Reserve
     Account exceeds the Available Subordinated Amount as of the end of such
     Transfer Date, the Servicer shall withdraw the amount of such excess from
     the Liquidity Reserve Account and allocate and pay such excess to the
     Seller.

         (d) Replacement Series 2000-1 Accounts. If, at any time, any of the
Series 2000- 1 Accounts ceases to be an Eligible Deposit Account, the Master
Trust Trustee (or the Servicer on its behalf) shall upon the earlier of (a) 30
calendar days, or (b) the next Determination Date, establish a new Series 2000-1
Account meeting the conditions specified in paragraphs (a), (b) or (c) above, as
applicable, as an Eligible Deposit Account and shall transfer any cash and/or
any investments to such new Series 2000-1 Account. Neither the Seller, the
Servicer nor any person or entity claiming by, through or under the Seller, the
Servicer or any such person or entity shall have any right, title or interest
in, or any right to withdraw any amount from, any Series 2000-1 Account, except
as expressly provided herein.

       SECTION 4.03 [Reserved.]

                     Collections.

            (v) Reimbursement of Class A Certificateholder Charge-Offs. An
     amount equal to the aggregate amount of unreimbursed Class A

            (ix) Reinstatement of Available Subordinated Amount. An amount equal
     to the excess, if any, of the Maximum Subordinated Amount as of the end of
     the preceding Transfer Date over the Available Subordinated Amount as of
     the end of the preceding Transfer Date shall be (A) during the Revolving
     Period or the Accumulation Period, allocated and paid to the Seller or (B)
     during an Early Amortization Period, deposited in the Liquidity Reserve
     Account, and in either case (A) or (B) the Available Subordinated Amount
     shall be reinstated by the amount of such payment or deposit.

            (x) Excess Interest Collections. Any remaining Available
     Certificateholder Interest Collections shall be treated as Excess Interest
     Collections, and applied pursuant to Section 4.03(f) of the Agreement.

                                       19
<PAGE>   23

If Available Certificateholder Interest Collections are not sufficient to
satisfy each of the applications described in clauses (i) through (ix) above on
any Transfer Date, then Excess Interest Collections from other Series allocable
to Series 2000-1 will be applied as Available Certificateholder Interest
Collections in the priority and the manner described in clauses (i) through (ix)
above. If Excess Interest Collections are less than the shortfalls for all
Series that provide for allocations of Excess Interest Collections, such Excess
Interest Collections shall be allocable to shortfalls for Series 2000- 1 and any
other Series that so provides pro rata based on the relative amounts of each
Series' shortfall.

     SECTION 4.05 Application of Available Seller's Finance Charge Collections,
Spread Account and Liquidity Reserve Account to Deficiency Amount.

         (a) On each Transfer Date, the Servicer shall determine the amount (the
"Deficiency Amount"), if any, by which the amount of the entire allocations
required on such Transfer Date by Sections 4.04(a)(i) through (vi) exceeds the
amount of Available Certificateholder Interest Collections for such Due Period
and Excess Interest Collections allocated to Series 2000-1 on such Transfer
Date, if any, for the related Due Period.

         (b) If the Deficiency Amount for any Transfer Date is greater than
zero, the Master Trust Trustee, acting in accordance with instructions from the
Servicer, shall apply available funds from the following sources in the
following order of priority in the same manner as Available Certificateholder
Interest Collections, each of which applications shall reduce such Deficiency
Amount (all such available funds being the "Available Draw Funds" for such
Transfer Date):

            (i) Available Seller's Finance Charge Collections;

            (ii) funds on deposit in the Spread Account;

            (iii) for any Transfer Date occurring during any Early Amortization
     Period, funds on deposit in the Liquidity Reserve Account;

provided, however, that the amount applied pursuant to this Section 4.05(b)
shall not exceed the Draw Amount. The Available Subordinated Amount shall be
reduced by the aggregate amount of Available Draw Funds applied pursuant to this
Section 4.05(b).

         (c) If all of the amounts applied pursuant to Section 4.05(a) and (b)
are insufficient to make the entire application described in Section
4.04(a)(iv), the Available Subordinated Amount shall be reduced (but not below
zero) by the amount of such deficiency and any remaining Investor Dealer Note
Losses shall be deemed to be reimbursed to the extent of such reduction.

     SECTION 4.06 Certificateholder Charge-Offs. If, for any Transfer Date on
which the Available Subordinated Amount equals or is reduced to zero (after
giving effect to the allocations, distributions, withdrawals and deposits to be
made on such Transfer Date) and the Deficiency Amount for such Transfer Date (as
reduced by the applications required by Section 4.05 of this Series Supplement)
is greater than zero, the Invested Amount shall be reduced by the lesser of (i)
such remaining Deficiency Amount for such Transfer Date and (ii) the amount of
Investor Dealer Note Losses for the related Due Period remaining unreimbursed
after all applications of funds or reductions

                                       20
<PAGE>   24

of the Available Subordinated Amount pursuant to Sections 4.04 and 4.05 (such
lesser amount being a "Certificateholder Charge-Off"). On any Transfer Date on
which Certificateholder Charge-Offs are greater than zero, such
Certificateholder Charge-Offs shall first reduce the Class B Invested Amount
(such amount being a "Class B Certificateholder Charge-Off") but not below zero;
and then reduce the Class A Invested Amount (such amount being a "Class A
Certificateholder Charge-Off") but not below zero.

     SECTION 4.07 Application of Seller's Finance Charge Collections.

         (a) Application of Available Seller's Finance Charge Collections. On
each Transfer Date, the Master Trust Trustee, acting in accordance with
instructions from the Servicer, shall withdraw and apply from the Collections
Account to the extent of Available Seller's Finance Charge Collections for the
related Due Period, the following amounts in the following order of priority:

            (i) On each Transfer Date related to a Due Period for which a
     Deficiency Amount exists, the amount required by Section 4.05(b)(i) shall
     be applied as specified in Section 4.05(b).

            (ii) On each Transfer Date related to a Due Period occurring during
     an Early Amortization Period, the amount, if any, by which the Available
     Subordinated Amount as of the end of such Transfer Date exceeds the amount
     of funds on deposit in the Liquidity Reserve Account shall be deposited in
     the Liquidity Reserve Account.

            (iii) On each Transfer Date on which the full Spread Account Deposit
     Amount was not deposited in the Spread Account pursuant to Section
     4.04(a)(vii), an amount equal to the shortfall in such Spread Account
     Deposit Amount shall be deposited in the Spread Account.

            (iv) Any remaining Available Seller's Finance Charge Collections for
     the related Due Period shall be allocated and paid to the Seller.

         (b) Application of Series Allocable Finance Charge Collections to the
Seller. On each Transfer Date, the Master Trust Trustee, acting in accordance
with instructions from the Servicer, shall withdraw from the Collections Account
and allocate and pay to the Seller an amount equal to the product of (i) the
result of the Excess Seller's Percentage for such Due Period minus the Required
Excess Seller Interest Percentage and (ii) Series Allocable Finance Charge
Collections for such Due Period.

     SECTION 4.08 Application of Series Allocable Principal Collections. On each
Business Day, the Master Trust Trustee, acting in accordance with instructions
from the Servicer, shall withdraw Series Allocable Principal Collections for
such Business Day from the Collections Account and apply such funds in the
following amounts:

         (a) Investor Principal Collections During Revolving Period. During the
Revolving Period, an amount equal to Investor Principal Collections for such
Business Day shall be treated as

                                       21
<PAGE>   25

Shared Principal Collections, and applied, pursuant to the written direction of
the Servicer, pursuant to Section 4.03(e) of the Agreement.

         (b) Investor Principal Collections During Accumulation Period or Early
Amortization Period. During the Accumulation Period or any Early Amortization
Period, Investor Principal Collections for such Business Day shall be allocated
to the Series 2000-1 Certificateholders and deposited into the Series Principal
Account to the extent the Invested Amount as of the preceding Distribution Date
exceeds the amount of funds on deposit in the Series Principal Account on such
Business Day; provided, however, that for each Business Day of a Due Period
occurring during the Accumulation Period, the amount of Investor Principal
Collections deposited in the Series Principal Account on such Business Day, when
added to the amount of Investor Principal Collections previously deposited in
the Series Principal Account during such Due Period, shall not exceed the
Controlled Deposit Amount for such Due Period. Any Investor Principal
Collections remaining after the applications described in the preceding sentence
shall be treated as Shared Principal Collections, and applied, pursuant to the
written direction of the Servicer, pursuant to Section 4.03(e) of the Agreement.

         (c) Seller's Principal Collections During the Revolving Period. During
the Revolving Period, all Seller's Principal Collections for such Business Day
shall be deemed to be Series 2000-1 Shared Seller Principal Collections and
shall be allocated as provided in Section 4.08(d)(iii).

         (d) Seller's Principal Collections During Accumulation Period or Early
Amortization Period; Shared Seller Principal Collections.

            (i) During the Accumulation Period, Available Seller's Principal
     Collections for such Business Day shall be deemed to be "Remaining
     Available Seller's Principal Collections," which shall be included in
     Series 2000-1 Shared Seller Principal Collections and allocated as provided
     in clause (iii) below. During the Accumulation Period, Excess Seller's
     Principal Collections shall be included in Series 2000-1 Shared Seller
     Principal Collections and allocated as provided in clause (iii) below.

            (ii) During any Early Amortization Period Available Seller's
     Principal Collections for such Business Day shall be deposited in the
     Liquidity Reserve Account to the extent the Available Subordinated Amount
     as of the end of the immediately preceding Transfer Date exceeds the amount
     of funds on deposit in the Liquidity Reserve Account (including amounts
     deposited pursuant to Section 4.07(a)(ii)). The amount required to be
     deposited pursuant to the preceding sentence shall be reduced by the amount
     of Available Seller's Finance Charge Collections deposited in the Liquidity
     Reserve Account on such Business Day. Any remaining Available Seller's
     Principal Collections for such Business Day shall be deemed to be
     "Remaining Available Seller's Principal Collections." During any Early
     Amortization Period, all Excess Seller's Principal Collections, all
     Remaining Available Seller's Principal Collections and all shared seller
     principal collections of any other Series that provides for shared seller
     principal collections not allocated in respect of principal shortfalls
     shall be allocated and paid to the Seller or deposited in the Excess
     Funding Account to the extent necessary to maintain the Master Trust
     Seller's Interest at an amount equal to (or, in the Seller's discretion,
     greater than) the Minimum Master Trust Seller's Interest.

<PAGE>   26

            (iii) During the Revolving Period or the Accumulation Period, Series
     2000- 1 Shared Seller Principal Collections, if any, and shared seller
     principal collections for any other Series that provides for shared seller
     principal collections shall be determined on each business day and
     allocated in the following priority: (i) to the 2000-1 Series to the extent
     of any Series 2000-1 Accumulation Period Principal Shortfall and to any
     other Series to the extent such Series provides for the use of shared
     seller principal collections in respect of principal shortfalls, (ii) to
     the Excess Funding Account to the extent necessary to maintain the Master
     Trust Seller's Interest at an amount equal to (or, in the discretion of the
     Seller, greater than) the Minimum Master Trust Seller's Interest, (iii) in
     the discretion of the Seller, to make payments on the principal balance of
     any variable funding certificates, and (iv) to the Seller or the holders of
     the Seller's Certificates. If shared seller principal collections for all
     Series, including Series 2000-1 Shared Seller Principal Collections, are
     less than the shortfalls for which shared seller principal collections may
     be used, including any Series 2000-1 Accumulation Period Principal
     Shortfall, then such shared seller principal collections will be allocated
     to all such shortfalls, including any Series 2000-1 Accumulation Period
     Principal Shortfall, pro rata based on the relative amounts of each such
     shortfall.

            (iv) "Series 2000-1 Shared Seller Principal Collections" means on
     each business day (i) during a Revolving Period, all Available Seller's
     Principal Collections and all Excess Seller's Principal Collections and
     (ii) during an Accumulation Period, all Remaining Available Seller's
     Principal Collections and all Excess Seller's Principal Collections. There
     shall be no Series 2000-1 Shared Seller Principal Collections during any
     Early Amortization Period.

         (e) If on any Distribution Date during an Early Amortization Period
after the application of all funds to be allocated or distributed on such date
the excess, if any, of (x) the Invested Amount over (y) the amount in the Series
Principal Account (the "Early Amortization Period Shortfall Amount") is less
than or equal to the aggregate amount of funds contained in the Liquidity
Reserve Account then funds shall be withdrawn in an amount equal to the Early
Amortization Period Shortfall Amount and shall be deposited in the Series
Principal Account.

     SECTION 4.09 Shared Principal Collections.

         (a) That portion of Shared Principal Collections for any Business Day
equal to the amount of Series 2000-1 Shared Principal Collections for such
Business Day will be allocated in the following priority: (i) to Series 2000-1
and applied in the same manner as Investor Principal Collections pursuant to
Section 4.08(b), (ii) deposited in the Excess Funding Account to the extent
necessary to maintain the Master Trust Seller's Interest at an amount equal to
(or, in the discretion of the Seller, greater than) the Minimum Master Trust
Seller's Interest, (iii) in the discretion of the Seller, paid on the principal
balance of any variable funding certificate or (iv) allocated to the Seller.

         (b) "Series 2000-1 Shared Principal Collections," with respect to any
Business Day, shall mean an amount equal to the Series 2000-1 Principal
Shortfall for such Business Day; provided, however, that, if the aggregate
amount of Shared Principal Collections for all Series for such Business Day is
less than the aggregate amount of Principal Shortfalls for all Series for such

                                       23
<PAGE>   27

Business Day, then Series 2000-1 Shared Principal Collections for such Business
Day shall equal the product of (x) Shared Principal Collections for all Series
for such Business Day and (y) a fraction, the numerator of which is the Series
2000-1 Principal Shortfall for such Business Day and denominator of which is the
aggregate amount of Principal Shortfalls for all Series for such Business Day.

     SECTION 4.10 Distributions to Series 2000-1 Certificateholders. On each
Transfer Date, after all allocations to the Distribution Account and the Series
Principal Account for the related Transfer Date have been made, the Master Trust
Trustee, acting in accordance with instructions from the Servicer, shall
transfer to the Distribution Account the funds on deposit in the Series
Principal Account and on each Distribution Date shall make, without duplication,
the following distributions from the Distribution Account:

         (a) Interest Distributions. On each Distribution Date (including the
Expected Principal Payment Date) first, Class A Monthly Interest will be
distributed to the Class A Certificateholders as accrued interest on the Class A
Certificates, and second, Class B Monthly Interest will be distributed to the
Class B Certificateholders as accrued interest on the Class B Certificates. To
the extent any interest is due but not distributed on any such Distribution
Date, such amount will be distributed on the following Distribution Date, along
with, to the extent permitted by law, interest at the applicable Certificate
Rate on such amount.

         (b) Expected Principal Payment Date. On the Expected Principal Payment
Date, in addition to the amount described in (a) above, amounts on deposit in
the Series Principal Account will be distributed as principal (up to a maximum
of the Invested Amount on such Distribution Date) first, to the Class A
Certificateholders (up to a maximum of the Class A Invested Amount on such
Distribution Date), and second, to the Class B Certificateholders (up to a
maximum of the Class B Invested Amount on such Distribution Date).

         (c) Early Amortization Period. On each Distribution Date related to a
Due Period occurring during an Early Amortization Period, in addition to the
amount described in (a) above, amounts on deposit in the Series Principal
Account will be distributed as principal first, to the Class A
Certificateholders (up to a maximum of the Class A Invested Amount on such
Distribution Date), and second, to the Class B Certificateholders (up to a
maximum of the Class B Invested Amount on such Distribution Date). Upon the
occurrence of an Early Amortization Event described in clause Section 6.01(b),
the distributions described in this Section 4.10(c) will begin on the first
Distribution Date occurring after the occurrence of such Early Amortization
Event.

     SECTION 4.11 Accumulation Period Length; Accumulation Period Commencement
Date. On or prior to the Distribution Date which is ten months prior to the
Distribution Date which is the Expected Principal Payment Date, the Servicer
shall determine in its sole discretion the Accumulation Period Length and the
Accumulation Period Commencement Date and, promptly following such
determination, the Servicer shall notify the Master Trust Trustee and the Rating
Agencies in writing of such determination.

     SECTION 4.12 Partial Month Due Period. The allocation and distribution
provisions in this Series Supplement are based upon the assumptions that each
Due Period will be a calendar month

                                       24
<PAGE>   28

and that each Due Period will have a unique related Transfer Date and
Distribution Date. However, under certain circumstances (such as the occurrence
of an Early Amortization Event, the Revolving Period could end on a date other
than the last day of a calendar month (the period from the first day of such
month (the "Subject Month") to and including the date of such occurrence being
referred to herein as the "Revolving Due Period"), and an Early Amortization
Period could commence on a date other than the first day of a calendar month
(the period from such other date until the last day of the Subject Month being
the "Amortizing Due Period"). If such a circumstance occurs, then the Servicer,
the Seller and the Master Trust Trustee shall observe the following rules:

            (i) the Transfer Date for both the Revolving Due Period and the
     Amortizing Due Period shall be the date on which the Transfer Date would
     have occurred if the Subject Month had been an ordinary Due Period;

            (ii) the allocations and distributions of Finance Charge Collections
     (and all items derived from Finance Charge Collections, such as Available
     Certificateholder Interest Collections and Available Seller's Finance
     Charge Collections) and Dealer Note Losses occurring during the Subject
     Month shall be made as if the Subject Month were one Due Period, without
     any distinction between the Revolving Due Period and the Amortizing Due
     Period; and

            (iii) two separate sets of allocations and distributions of
     Principal Collections (and all items derived from Principal Collections,
     such as Investor Principal Collections and Seller's Principal Collections)
     shall be made on such Transfer Date, according to whether such Principal
     Collections were received during the Revolving Due Period (in which case
     allocations and distributions shall be made as provided in Sections 4.08(a)
     and (c)) or the Amortizing Due Period (in which case allocations and
     distributions shall be made as provided in Sections 4.08(b) and (d)).

     SECTION 4.13 Additional Rights upon the Occurrence of Certain Events.
Notwithstanding the provisions of Section 9.02(a) of the Agreement, if any
insolvency event occurs with respect to the Seller, Navistar International
Corporation, International Truck and Engine Corporation or Navistar Financial
Corporation, on the day of such insolvency event, the Seller will (subject to
the actions of the Certificateholders) immediately cease to transfer Dealer
Notes to the Master Trust, and promptly give notice to the Master Trust Trustee
of such insolvency event. Under the terms of the Pooling and Servicing
Agreement, if an insolvency event occurs with respect to the Seller prior to the
date on which the Series 2000-1 Certificates issued by the Master Trust have
been paid in full, then within 15 days the Master Trust Trustee will publish a
notice of such insolvency event stating that the Master Trust Trustee intends to
sell, liquidate or otherwise dispose of the Dealer Notes in a commercially
reasonable manner and on commercially reasonable terms, unless within a
specified period of time Certificateholders representing more than 50% of the
aggregate series invested amount of the senior most outstanding Class of
Investor Certificates of each such Series and each person holding a Supplemental
Certificate, instruct the Master Trust Trustee not to sell, dispose of or
otherwise liquidate the Dealer Notes and to continue transferring Dealer Notes
as before such insolvency event.
