                             OF THE VFC CERTIFICATES

            SECTION 2.1. Designation. The Certificates and interests created and
authorized pursuant to the Agreement and this Supplement shall be divided into
two Classes, which shall be designated respectively as (i) the "VFC
Certificates, Series 1998-1" and (ii) an interest designated as the "Series

            SECTION 2.2. The Series 1998-1 Interests. (a) The VFC Certificates
shall represent fractional undivided interests in the Trust, including the right
to receive distributions from (i) the Invested Percentage (expressed as a
decimal) of Collections received with respect to the Receivables and all other
funds on deposit in the Collection Accounts and (ii) all other funds on deposit
in the Series Collection Subaccounts and any subaccounts thereof (collectively,

undivided interest in the Trust, consisting of the right to receive Collections
with respect to the Receivables allocated to the VFC Certificateholders'

Initial Purchase. Subject to the terms and conditions of this Supplement,
including delivery of notice in accordance with Section 2.4, (i) on the Issuance
Date, (A) the Initial Purchaser may, in its sole discretion, purchase a VFC
Certificate in an amount equal to the Initial Series 1998-1 Invested Amount or
(B) if the Initial Purchaser shall have notified the Funding Agent that it has
elected not to purchase a VFC Certificate on the Issuance Date, each APA Bank
hereby severally agrees to purchase on the Issuance Date a VFC Certificate in an
amount equal to such APA Bank's Commitment Percentage of the Initial Series
1998-1 Invested Amount and (ii) thereafter, (A) if the Initial Purchaser shall
have purchased a VFC Certificate on the Issuance Date, the Initial Purchaser
may, in its sole discretion, maintain its VFC Certificate, subject to increase
or decrease during the Series 1998-1 Revolving Period, in accordance with the
provisions of this Supplement and (B) if the APA Banks shall have purchased VFC
Certificates on the Issuance Date or, in any case, on or after the APA Bank

Company hereby agrees to maintain ownership of the Series 1998-1 Subordinated

            (c) Maximum Series 1998-1 Purchaser Invested Amount. Notwithstanding
anything to the contrary contained in this Supplement, at no time shall the
Series 1998-1 Purchaser Invested Amount (calculated without regard to clauses
(d) and (e) of the definition thereof) of any APA Bank exceed such APA Bank's
Commitment at such time.

            SECTION 2.4. Delivery. On the Issuance Date, the Company shall sign,
on behalf of the Trust, and shall direct the Trustee in writing pursuant to
Section 5.2 of the Agreement to duly authenticate, and the Trustee, upon
receiving such direction, shall so authenticate (i) the VFC Certificates in such
names and such denominations and deliver such VFC Certificates to the Funding
Agent, on behalf of the Initial Purchaser, or the APA Banks, as the case may be,
in accordance with such written directions. The VFC Certificates shall be issued
in minimum denominations of $1,000,000 and in integral multiples of $100,000 in
excess

                                                                              22


thereof. The Trustee shall mark on its books the actual Series 1998-1 Invested

            SECTION 2.5. Procedure for Initial Issuance and for Increasing the

Initial Purchaser may agree, in its sole discretion, and each APA Bank hereby
agrees to purchase a VFC Certificate in accordance with Section 2.3 and (ii) on
any Business Day during the Commitment Period, the Initial Purchaser may agree,
in its sole discretion, and each APA Bank hereby agrees that the Series 1998-1
Invested Amount may be increased by increasing such Purchaser's Series 1998-1
Purchaser Invested Amount (an "Increase"), upon the request of the Servicer or
the Company on behalf of the Trust (each date on which an increase in the Series
1998-1 Invested Amount occurs hereunder being herein referred to as the
"Increase Date" applicable to such Increase); provided, however, that the
Servicer or the Company, as the case may be, shall have given the Funding Agent
(with a copy to the Trustee) irrevocable written notice (effective upon
receipt), substantially in the form of Exhibit F hereto, of such request no
later than (i) 1:00 p.m., New York City time, two Business Days prior to the
Issuance Date or such Increase Date, as the case may be, in the case of any
Increase Date occurring prior to the APA Bank Purchase Date or (ii) (x) if the
Initial Series 1998-1 Invested Amount or Increase Amount is to be priced solely
with reference to the ABR, on or prior to 12:00 noon, New York City time, on the
Issuance Date or such Increase Date, as the case may be, or (y) if all or a
portion of the Initial Series 1998-1 Invested Amount or Increase Amount is to be
allocated to a Eurodollar Tranche, 1:00 p.m., New York City time, three Business
Days prior to the Issuance Date or such Increase Date, as the case may be, in
the case of any Increase Date occurring on or after the APA Bank Purchase Date;
provided, further, that the provisions of this subsection shall not restrict the
allocations of Collections pursuant to Article III. Such notice shall state (x)
the Issuance Date or the Increase Date, as the case may be, (y) the initial
invested amount (the "Initial Series 1998-1 Invested Amount"), or the proposed
amount of such Increase (the "Increase Amount"), as the case may be, and (z) on
and after the APA Bank Purchase Date, what portions thereof will be allocated to
a Eurodollar Tranche and the Floating Tranche.

            (b) If, prior to the APA Bank Purchase Date, the Initial Purchaser
elects not to fund any portion of a requested Increase, the Initial Purchaser
shall notify the Funding Agent thereof and deliver a Sale Notice in accordance
with Section 2.6 and each APA Bank shall purchase its Commitment Percentage of
the Initial Purchaser's Series 1998-1 Purchaser Invested Amount in accordance
with Section 2.6 and fund such Increase in an amount equal to its Commitment
Percentage of such Increase; provided, however that an APA Bank shall not be
obligated to fund any portion of an Increase that would cause its Series 1998-1
Purchaser Invested Amount to exceed its Commitment.

            (c) The Purchasers shall not be required to make the initial
purchase of VFC Certificates on the Issuance Date or to increase their
respective Series 1998-1 Purchaser Invested Amounts on any Increase Date
hereunder unless:

                  (i) the related aggregate initial purchase amount or Increase
      Amount is equal to $1,000,000 or an integral multiple of $100,000 in
      excess thereof;

                                                                              23


                  (ii) after giving effect to the initial purchase amount or
      Increase Amount, (A) the Series 1998-1 Invested Amount would not exceed
      the Maximum Commitment Amount on the Issuance Date or such Increase Date,
      as the case may be, and (B) the Series 1998-1 Allocated Receivables Amount
      would not be less than the Series 1998-1 Target Receivables Amount on the
      Issuance Date or such Increase Date, as the case may be;

                  (iii) no Early Amortization Event or Potential Early
      Amortization Event shall have occurred and be continuing;

                  (iv) in the case of any funding by the Initial Purchaser, no
      PARCO Wind-Down Event or Potential PARCO Wind-Down Event shall have
      occurred and be continuing; and

                  (v) all of the representations and warranties made by each of
      the Company and the Servicer in each Transaction Document to which it is a
      party are true and correct in all material respects on and as of the
      Issuance Date or such Increase Date, as the case may be, as if made on and
      as of such date (except to the extent such representations and warranties
      are expressly made as of another date).

The Company's acceptance of funds in connection with (x) the Purchasers' initial
purchase of VFC Certificates on the Issuance Date and (y) each Increase
occurring on any Increase Date shall constitute a representation and warranty by
the Company to the Purchasers as of the Issuance Date or such Increase Date
(except to the extent such representations and warranties are expressly made as
of another date or relate to particular receivables), as the case may be, that
all of the conditions contained in this subsection 2.5(c) have been satisfied.

            (d) After receipt by the Funding Agent of the notice required by
subsection 2.5(a) from the Servicer or the Company on behalf of the Trust, the
Funding Agent shall, so long as the conditions set forth in subsections 2.5(a)
and (c) are satisfied, promptly provide telephonic notice (i) prior to the APA
Bank Purchase Date, to the Initial Purchaser, and (ii) on and after the APA Bank
Purchase Date, to each APA Bank, of the Increase Date and of the portion of the
Increase Amount allocable to such APA Bank (which shall equal such APA Bank's
Commitment Percentage of the Increase Amount). If the Initial Purchaser elects
to fund an Increase, the Initial Purchaser agrees to pay in immediately
available funds the amount of such Increase on the related Increase Date to the
Funding Agent for payment to the Trust for deposit in the Series 1998-1
Principal Collection Sub-subaccount. On or after the APA Bank Purchase Date,
each APA Bank agrees to pay in immediately available funds such APA Bank's
Commitment Percentage of each Increase on the related Increase Date to the
Funding Agent for payment to the Trust for deposit in the Series 1998-1
Principal Collection Sub-subaccount.

            SECTION 2.6. Sale by the Initial Purchaser of its Series 1998-1
Purchaser Invested Amount to the APA Banks. (a) On any date during the
Commitment Period, the Initial Purchaser may, in its own discretion, and the
Initial Purchaser shall upon the occurrence of a PARCO Wind-Down Event, in each
case, by delivering a Sale Notice to the Funding Agent, the Company and the
Trustee, sell to the APA Banks (in accordance with their respective Commitment
Percentages) and each APA Bank hereby agrees to purchase its Commitment
Percentage of all right, title and interest of the Initial Purchaser in its
Series 1998-1 Purchaser Invested Amount. Any Sale Notice shall be delivered by
the Initial Purchaser to the Funding Agent, the Company and the Trustee prior to
12:30 p.m., New York City time, on the APA Bank

                                                                              24


Purchase Date and shall constitute an irrevocable offer by the Initial Purchaser
to sell 100% of its Series 1998-1 Purchaser Invested Amount at the Purchase
Price. Any Sale Notice shall be deemed to be a representation and warranty by
the Initial Purchaser that no PARCO Insolvency Event shall have occurred and be
continuing. Each APA Bank hereby agrees to purchase from the Initial Purchaser
such APA Bank's Commitment Percentage of the Initial Purchaser's Series 1998-1
Purchaser Invested Amount for a purchase price equal to such APA Bank's
Commitment Percentage of the Purchase Price on the APA Bank Purchase Date (which
date, subject to subsection 2.6(b), may be the same as the date of the Sale
Notice). Notwithstanding anything to the contrary set forth in this Supplement,
no APA Bank shall have any obligation to purchase the Initial Purchaser's Series
1998-1 Purchaser Invested Amount if, on such Purchase Date, any PARCO Insolvency
Event shall have occurred and be continuing.

            (b) If, at or prior to 12:30 p.m., New York City time, on any
Business Day, the Initial Purchaser delivers the Sale Notice to the Funding
Agent specifying that the APA Bank Purchase Date shall be the same date as the
date of the Sale Notice, the Funding Agent shall, by no later than 1:00 p.m.,
New York City time, notify (by telecopy or by telephone call promptly confirmed
in writing by telecopy) each APA Bank of the receipt and content of the Sale
Notice. Each APA Bank shall purchase its Commitment Percentage of the Initial
Purchaser's VFC Certificate by depositing its Commitment Percentage of the
Purchase Price in immediately available funds into the account(s) specified by
the Initial Purchaser in the Sale Notice no later than 2:00 p.m., New York City
time. If the Initial Purchaser delivers the Sale Notice to the Funding Agent
after 12:30 p.m., New York City time, on any Business Day or the Initial
Purchaser delivers the Sale Notice to the Funding Agent specifying that the APA
Bank Purchase Date shall be a date other than the date of the Sale Notice, the
Funding Agent shall promptly advise (by telecopy or by telephone call promptly
confirmed in writing by telecopy) each APA Bank of the receipt and content of
the Sale Notice. Notwithstanding the fact that the APA Bank Purchase Date may
occur on a date which is later than the date on which the Sale Notice is
delivered to the Funding Agent, the several obligations of each APA Bank to make
such purchase and to make payment of the amounts required to be paid by it
pursuant to subsection 2.6(a) shall arise immediately upon receipt by the
Funding Agent of the Sale Notice. Upon payment of the Purchase Price as provided
herein and delivery to the Trustee by the Funding Agent of the Initial
Purchaser's VFC Certificate, the Company shall sign, on behalf of the Trust, and
shall direct the Trustee in writing to duly authenticate, and the Trustee, upon
receiving such direction, shall so authenticate, a new VFC Certificate in the
name of each APA Bank and in a denomination equal to such APA Bank's Commitment
Percentage as set forth in such written direction and shall deliver such VFC
Certificate to each such APA Bank in accordance with such written direction.

            (c) If, by 2:00 p.m., New York City time, one or more APA Banks
(each, a "Defaulting APA Bank," and each APA Bank other than the Defaulting APA
Bank being referred to as a "Non-Defaulting APA Bank") fails to make its
Commitment Percentage of the Purchase Price available to the Funding Agent
pursuant to subsection 2.6(b) (the aggregate amount not so made available to the
Funding Agent being herein called the "Purchase Price Deficit"), then the
Funding Agent shall, by no later than 2:30 p.m., New York City time, instruct
each Non-Defaulting APA Bank to pay, by no later than 3:00 p.m., New York City
time, in immediately available funds, to the account designated by the Funding
Agent, an amount equal to the lesser of (x) such Non-Defaulting APA Bank's
proportionate share (based upon the relative Commitments of the Non-Defaulting
APA Banks) of the Purchase Price Deficit and (y) its unused Commitment. A
Defaulting APA Bank shall forthwith, upon demand, pay to the Funding Agent for
the ratable benefit of the Non-Defaulting APA Banks all amounts paid by

                                                                              25


each Non-Defaulting APA Bank on behalf of such Defaulting APA Bank, together
with interest thereon, for each day from the date a payment was made by a
Non-Defaulting APA Bank until the date such Non-Defaulting APA Bank has been
paid such amounts in full, at a rate per annum equal to the sum of the Federal
Funds Effective Rate plus 2%. In addition, without prejudice to any other rights
that the Initial Purchaser may have under applicable law, each Defaulting APA
Bank shall pay to the Initial Purchaser forthwith upon demand, the difference
between the Defaulting APA Bank's unpaid Commitment Percentage of the Purchase
Price and the amount paid with respect thereto by the Non-Defaulting APA Banks,
together with interest thereon, for each day from the date of the Funding
Agent's request for such Defaulting APA Bank's Commitment Percentage of the
Purchase Price pursuant to Section 2.6(b) until the date the requisite amount is
paid to the Initial Purchaser in full, at a rate per annum equal to the sum of
the Federal Funds Effective Rate plus 2%.

            (d) The transfer of the Initial Purchaser's VFC Certificate pursuant
to this Section 2.6 shall be without recourse or warranty, express or implied,
except that the Initial Purchasers represent that such VFC Certificate is free
and clear of adverse claims created by or arising as a result of claims against
the Initial Purchaser. By executing and delivering a Sale Notice pursuant to
Section 2.6(a), (i) the Initial Purchaser makes no representation or warranty
and assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with the VFC Certificate or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of the VFC Certificate, or any other agreement, instrument or other document
furnished pursuant thereto or in connection therewith, including without
limitation any Transaction Document, and (ii) the Initial Purchaser makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of the Trust, the Trustee, the Servicer, each Sub-Servicer,
each Seller or any Obligor (collectively, the "Transaction Parties") or the
Funding Agent, or the performance or observance by the Transaction Parties of
any of their respective obligations under the VFC Certificate or the Transaction
Documents.

            (e) If the Adjusted Liquidity Price on the APA Bank Purchase Date is
less than the Series 1998-1 Invested Amount on the APA Bank Purchase Date (the
amount of such insufficiency, the "PARCO Residual Amount"), each APA Bank agrees
that (i) on each Distribution Date after the APA Bank Purchase Date on which
interest is distributed to VFC Certificateholders pursuant to subsection
3A.6(a), the Funding Agent shall distribute to the Initial Purchaser its
Reduction Percentage of such interest payments and (ii) on each Distribution
Date after the APA Purchase Date on which amounts in reduction of the Series
1998-1 Invested Amount are distributed to VFC Certificateholders pursuant to
Section 2.7 or subsection 3A.6(c), the Funding Agent shall distribute to the
Initial Purchaser its Reduction Percentage of such amounts only after the Series
1998-1 Invested Amount has been paid in full.

            SECTION 2.7. Procedure for Decreasing the Series 1998-1 Invested
Amount; Optional Termination. (a) On any Business Day during the Series 1998-1
Revolving Period or the Series 1998-1 Amortization Period (except for
Distribution Dates during the Series 1998-1 Amortization Period (which shall be
governed by subsection 3A.6(c))), upon the written request of the Servicer or
the Company on behalf of the Trust, the Series 1998-1 Invested Amount may be
reduced (a "Decrease") by the distribution by the Trustee to the Funding Agent
for the pro rata benefit of the Purchasers in accordance with their respective
Series 1998-1 Purchaser Invested Amounts of funds on deposit in the Series
1998-1 Principal Collection Sub-subaccount on such day in an amount not to
exceed the amount of such funds on deposit on such day; provided that the
Servicer shall have given the Funding Agent (with a copy to the Trustee)

                                                                              26


irrevocable written notice (effective upon receipt), prior to 1:00 p.m., New
York City time, (i) on the second Business Day prior to such Decrease, in the
case of any Decrease occurring prior to the APA Bank Purchase Date and (ii) (A)
if the Decrease relates solely to a Floating Tranche, on the Business Day of
such Decrease or (B) if all or any portion of the Decrease relates to a
Eurodollar Tranche, on the Business Day that is three Business Days prior to
such Decrease, and which notice shall state the amount of such Decrease;
provided, further, that (x) such Decrease shall be in an amount equal to
$1,000,000 and integral multiples of $100,000 in excess thereof or if the Series
1998-1 Invested Amount is less than $1,000,000 then such Decrease shall equal
the Series 1998-1 Invested Amount, and (y) prior to the APA Bank Purchase Date,
such Decrease shall be in an amount no greater than the Unallocated Balance on
such day.

            (b) Simultaneously with any such Decrease during the Series 1998-1
Revolving Period, the Series 1998-1 Subordinated Interest Amount shall be
reduced by an amount (the "Series 1998-1 Subordinated Interest Reduction
Amount") such that the Series 1998-1 Subordinated Interest Amount shall equal
the Series 1998-1 Required Reserves after giving effect to such Decrease. During
the Series 1998-1 Revolving Period, after the distribution described in
subsection (a) above has been made, and the Series 1998-1 Subordinated Interest
Amount shall have been reduced by the Series 1998-1 Subordinated Interest
Reduction Amount, a distribution shall be made to the owner of the Series 1998-1
Subordinated Interest out of remaining funds on deposit in the Series 1998-1
Principal Collection Sub-subaccount in an amount equal to the lesser of (x) the
Series 1998-1 Subordinated Interest Reduction Amount and (y) the amount of such
remaining funds on deposit in the Series 1998-1 Principal Collection
Sub-subaccount.

            (c) On or after the APA Bank Purchase Date, any reduction in the
Series 1998-1 Invested Amount on any Business Day shall be allocated first to
reduce the Unallocated Balance and then to reduce the portion of the Series
1998-1 Invested Amount allocated to Eurodollar Tranches in such order as the
Company may select in order to minimize costs payable pursuant to Section 7.4.

            (d) (i) On any Business Day unless the Scheduled Revolving
Termination Date, an Early Amortization Event or a Potential Early Amortization
Event shall have occurred and be continuing, the Company shall have the right to
deliver an irrevocable written notice (an "Optional Termination Notice") to the
Trustee, the Servicer and the Rating Agencies in which the Company declares that
the Series 1998-1 Revolving Period shall terminate on the date (the "Optional
Termination Date") set forth in such notice (which date, in any event, shall be
the last day of a Settlement Period which is not less than 10 days from the date
on which such notice is delivered).

            (ii) From and after the Optional Termination Date, the Series 1998-1
Amortization Period shall commence for all purposes under this Agreement and the
other Transaction Documents. The Trustee shall give prompt written notice of its
receipt of an Optional Termination Notice to the Purchasers and each Rating
Agency.

            SECTION 2.8. Reductions of the Commitments. (a) On any Business Day
during the Series 1998-1 Revolving Period, the Company, on behalf of the Trust,
may, upon three Business Days' prior written notice to the Funding Agent
(effective upon receipt) (with copies to the Servicer and the Trustee) reduce or
terminate the Commitments (a "Commitment Reduction") in an aggregate amount
equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof;
provided that no such termination or reduction shall be permitted if, after
giving

                                                                              27


effect thereto and to any reduction in the Series 1998-1 Invested Amount on such
date, the Series 1998-1 Invested Amount would exceed the Aggregate Commitment
Amount then in effect. Each APA Banks's Commitment shall be reduced by such APA
Bank's Commitment Percentage of the amount of such Commitment Reduction.

            (b) On any Business Day subsequent to the APA Bank Purchase Date, if
an Early Amortization Period has commenced, the Aggregate Commitment Amount
shall be reduced to the Series 1998-1 Invested Amount. Each APA Bank's
Commitment shall be reduced by an amount equal to such APA Bank's Commitment
Percentage times the amount of such reduction.

            (c) Once reduced, the Commitments may not be subsequently
reinstated. Upon effectiveness of any such reduction, the Funding Agent shall
prepare a revised Schedule 1 to reflect the reduced Commitment of each APA Bank
and Schedule 1 of this Supplement shall be deemed to be automatically superseded
by such revised Schedule 1. The Funding Agent shall distribute such revised
Schedule 1 to the Company, the Servicer, the Trustee and each APA Bank.

            SECTION 2.9. Interest; Fees. (a) Interest shall be payable on the
VFC Certificates on each Distribution Date pursuant to subsection 3A.6(a).

            (b) The Trustee (acting at the written direction of the Servicer
upon which the Trustee may conclusively rely) shall distribute pursuant to
subsection 3A.6(b), from amounts on deposit in the Series 1998-1 Non-Principal
Collection Sub-subaccount, to the Funding Agent, for the pro rata account of the
APA Banks in accordance with their respective Commitment Percentages, on each
Distribution Date, a commitment fee with respect to each Accrual Period ending
on such date (the "Commitment Fee") (i) during the Series 1998-1 Revolving
Period at the Commitment Fee Rate of the average daily excess of the Aggregate
Commitment Amount over the average aggregate Series 1998-1 Purchaser Invested
Amounts of the APA Banks during such Accrual Period and (ii) during the Series
1998-1 Amortization Period at the Commitment Fee Rate of the average daily
Series 1998-1 Invested Amount during such Accrual Period; provided however, that
no Commitment Fee will be payable hereunder for any Accrual Period or portion
thereof during the Series 1998-1 Amortization Period that commences on or after
the APA Bank Purchase Date. The Commitment Fee shall be payable (i) monthly in
arrears on each Distribution Date and (ii) on the Commitment Termination Date.
To the extent that funds on deposit in the Series 1998-1 Non-Principal
Collection Sub-subaccount at any such date are insufficient to pay the
Commitment Fee due on such date, the Servicer shall so notify the Company and
the Company shall immediately pay the Funding Agent the amount of any such
deficiency.

            (c) The Trustee (acting at the written direction of the Servicer
upon which the Trustee may conclusively rely) shall distribute pursuant to
subsection 3A.6(b), from amounts on deposit in the Series 1998-1 Non-Principal
Collection Sub-subaccount, to the Funding Agent, for the account of the Initial
Purchaser, on each Distribution Date prior to the APA Bank Purchase Date and on
the Distribution Date immediately succeeding the APA Bank Purchase Date, a
facility fee (the "Facility Fee") with respect to each Accrual Period ending on
such date (or, in the case of the Distribution Date immediately succeeding the
APA Bank Purchase Date, the period from and including the immediately preceding
Distribution Date to but excluding the APA Bank Purchase Date) (i) during the
Series 1998-1 Revolving Period, at the Facility Fee Rate of the average daily
Aggregate Commitment Amount during such period and (ii) during the Series 1998-1
Amortization Period, at the Facility Fee Rate of the average daily Series 1998-1

                                                                              28


Invested Amount during such period. The Facility Fee shall be payable (i)
monthly in arrears on each Distribution Date prior to the APA Bank Purchase Date
and (ii) on the Distribution Date immediately succeeding the APA Bank Purchase
Date. To the extent that funds on deposit in the Series 1998-1 Non-Principal
Collection Sub-subaccount at any such date are insufficient to pay the Facility
Fee due on such date, the Servicer shall so notify the Company and the Company
shall immediately pay the Funding Agent the amount of any such deficiency.

            (d) Calculations of per annum rates and fees under this Supplement
shall be made on the basis of a 360- (or 365-/366-, in the case of interest on
the Floating Tranche based on the ABR) day year with respect to Commitment Fees,
Facility Fees and interest rates. Each determination of the Eurodollar Rate by
the Funding Agent shall be conclusive and binding upon each of the parties
hereto in the absence of manifest error.

            SECTION 2.10. Indemnification by the Company and the Servicer. (a)
The Company agrees to indemnify and hold harmless the Trustee, the Funding
Agent, each Purchaser and each of their respective officers, directors, agents

of such Company indemnified person or its officers, directors, agents,
principals, employees or employers, (B) resulted solely from a default by an
Obligor with respect to any Receivable or (C) include any income or franchise
taxes imposed on (or measured by) any Company indemnified person's net income;
provided that any payments made by the Company pursuant to this subsection shall
be made solely from funds available to the Company which are not otherwise
required to be applied to the payment of any amounts (other than amounts payable
to the Company) pursuant to any Pooling and Servicing Agreements, shall be
non-recourse other than with respect to such funds, and shall not constitute a
claim against the Company to the extent that insufficient funds exist to make
such payment.

            (b) The Servicer agrees to indemnify and hold harmless the Trustee,
the Funding Agent, each Purchaser and each of their respective officers,

other Transaction

                                                                              29


Documents, including, but not limited to, any judgment, award, settlement,
reasonable attorneys' fees and other reasonable costs or expenses incurred in
connection with the defense of any actual or threatened action, proceeding or
claim, except to the extent such loss, liability, expense, damage or injury

direction of the Servicer, and based solely on the Daily Report upon which the
Trustee may conclusively rely:

            (a) The portion of the Aggregate Daily Collections allocated to the
Series 1998-1 Interests pursuant to Article III of the Agreement shall be
allocated and distributed on each Business Day as set forth in this Article III
by the Trustee as follows:

      the Series 1998-1 Collection Subaccount is less than the Accrued Expense
      Amount required to be transferred to the Series 1998-1 Non-Principal
      Collection Sub-subaccount, then an amount equal to the shortfall shall be
      retained, first, in the Series 1998-1 Canada/U.S. Dollar Collection
      Subaccount and, second, to the extent of any remaining shortfall, in the
      Series 1998-1 Canada/Canadian Dollar Collection Subaccount; and provided

      shall be payable by the Initial Purchaser, upon the request of the
      Servicer or, after the commencement of an Early Amortization Period, the
      Funding Agent, the Trustee shall distribute to the Funding Agent an amount

Business Day and any retention of funds in the Series 1998-1 Canada/U.S. Dollar
Collection Subaccount and the Series 1998-1 Canada/Canadian Dollar Collection
Subaccount and (y) any deposit resulting from an Increase, if any, pursuant to
subsection 2.5(c) on such Business Day, amounts on deposit in the Series 1998-1

Company (but only to the extent that the Trustee has received a Daily Report
which reflects the receipt of the Collections on deposit therein) not later than
2:00 p.m., New York City time, in accordance with directions contained in the
Daily Report; provided that such distribution shall be made only if no Early
Amortization Event or Potential Early Amortization Event in each case set forth

is continuing and only to the extent that, if after giving effect to such
distribution, the Series 1998-1 Target Receivables Amount would not exceed the
Series 1998-1 Allocated Receivables Amount; provided further that if notice of
any Liens of the type described in subsection (j) of Section 5.1 of this
Supplement shall be filed against WESCO, the Company or the Trust that, in any
one instance or in the aggregate secures an amount that is less than $1,000,000,
the Trustee shall withhold from such distribution the aggregate amount secured
by such Liens, until there shall have been delivered to the Trustee and each
Rating Agency proof of the release of, or payment of the amounts secured by,
such Liens; provided further that if the Company or the Servicer, on behalf of
the Company, shall have given the Funding Agent irrevocable written notice
(effective upon receipt) at least two Business Days prior to such day, in the
case of any notice given prior to the APA Bank Purchase Date, on such day, in
the case of any notice given on or after the APA Bank Purchase Date with respect
to the Floating Tranche, or at least three Business Days prior to such day, in
the case of any notice given on or after the APA Bank Purchase Date with respect
to the Eurodollar Tranche, the Company or the Servicer may instruct the Trustee
in writing (specifying the related amount) to withdraw all or a portion of such
amounts on deposit in the Series 1998-1 Principal Collection Sub-subaccount and
apply such withdrawn amounts toward the reduction of the Series 1998-1 Invested
Amount and the Series 1998-1 Subordinated Interest Amount in accordance with
Section 2.7. Amounts distributed to the Company hereunder shall be deemed to be
paid first from Collections received directly by the Servicer and second from
Collections received in the Lockboxes.

immediately preceding the next Distribution Date and shall be distributed on
such Distribution Date in accordance with subsection 3A.6(c). Except as set

Company or the owner of the Series 1998-1 Subordinated Interest during the
Series 1998-1 Amortization Period.

            (c) On each Business Day, an amount equal to the Daily Interest
Deposit for such day shall be transferred by the Trustee from the Series 1998-1
Non-Principal Collection Sub-subaccount to the Series 1998-1 Accrued Interest
Sub-subaccount.

            (d) The allocations to be made pursuant to this Section 3A.3 are
subject to the provisions of Sections 2.5, 2.7, 7.2 and 9.1 of the Agreement.

      SECTION 3A.4. Determination of Interest. (a) (i) The amount of interest
distributable with respect to the VFC Certificates ("Series 1998-1 Monthly
Interest") on each Distribution Date shall be the amount of Daily Interest
Expense accrued during the Accrual Period ending on such Distribution Date.

                  (ii) If a change in the CP Rate, the weighted average
      Eurodollar Rate or the ABR on or after any Settlement Report Date or any
      withdrawal pursuant to the proviso in subsection 3A.3(a)(ii) results in a
      change in Series 1998-1 Monthly Interest for the Accrual Period ending on
      the Distribution Date immediately succeeding such Settlement Report Date,
      the Servicer shall amend the Monthly Settlement Statement to reflect the
      adjustment in the Series 1998-1 Monthly Interest for such Accrual Period
      caused by such change or withdrawal and any consequent adjustments and the
      Servicer shall also provide written notification to the Trustee of any
      such change. Any amendment to the Monthly Settlement Statement pursuant to
      this subsection 3A.4(a)(ii) shall be completed by 1:00 p.m. on the day
      preceding the next Distribution Date.

            (b) On each Distribution Date, the Servicer shall determine the
excess, if any (the "Interest Shortfall"), of (i) the Series 1998-1 Monthly
Interest for the Accrual Period ending on such Distribution Date over (ii) the
amount which will be available to be distributed to the Purchasers on such
Distribution Date in respect thereof pursuant to this Supplement. If the
Interest Shortfall with respect to any Distribution Date is greater than zero,
an additional amount ("Additional Interest") equal to the product of (A) the
number of days until such Interest Shortfall shall be repaid divided by 365 (or
366, as the case may be), (B) the ABR plus 2.0% and (C) such Interest Shortfall
(or the portion thereof which has not been paid to the Purchasers) shall be
payable as provided herein with respect to the VFC Certificates on each
Distribution Date following such Distribution Date, to but excluding the
Distribution Date on which such Interest Shortfall is paid to the VFC
Certificateholders.

            (c) On any Business Day, the Company may, subject to subsection
3A.4(e), elect to allocate all or any portion of the Available Pricing Amount
(i), prior to the APA Bank Purchase Date, to one or more CP Tranches with CP
Rate Periods commencing on such Business Day by giving the Funding Agent
irrevocable written or telephonic (confirmed in writing) notice thereof, which
notice must be received by the Funding Agent prior to 1:00 p.m., New York City
time, two Business Days prior to such Business Day or (ii) on or after the APA
Bank Purchase Date, to one or more Eurodollar Tranches with Eurodollar Periods
commencing on such Business Day by giving the Funding Agent irrevocable written

immediately preceding Settlement Report Date; provided, however, that the Series
1998-1 Monthly Principal Payment on any Distribution Date shall not exceed the
Series 1998-1 Invested Amount on such Distribution Date after giving effect to
the reductions and increases pursuant to paragraphs (b) and (c) below. In

      not below zero) by such remaining Series 1998-1 Allocable Charged-Off
      Amount (which shall also be reduced by the amount so applied).

            (c) Increases to Series 1998-1 Principal. If, on any Special

                                                                              40


then, in the case of (x) any event described in Section 7.1 of the Agreement and
paragraphs (h), (i) and (o) above, automatically without any notice or action on
the part of the Trustee or Purchasers, an early amortization period shall
immediately commence or (y) any other event described above, after the
applicable grace period (if any) set forth in such subsections, the Trustee may,
and at the written direction of the Required APA Banks shall, by written notice
then given to the Company and the Servicer, declare that an early amortization
period has commenced as of the date of such notice with respect to Series 1998-1
(any such period under clause (x) or (y) above, an "Early Amortization Period");
provided however, that in the case of the event described in clause (g) above,
if an Early Amortization Period has not been declared within ten Business Days
after the occurrence of such event, then an Early Amortization Period shall
occur automatically unless, (i) prior to the end of such ten Business Day
period, the Series 1998-1 Allocated Receivables Amount shall no longer be less
than the Series 1998-1 Target Receivables Amount and (ii) so long as the Series
1998-1 Allocated Receivables Amount continues to be equal to or greater than the
Series 1998-1 Target Receivables Amount, the Majority Purchasers shall have
waived the occurrence of such event.

                                   ARTICLE VI

                                  SERVICING FEE

            SECTION 6.1. Servicing Compensation. A monthly servicing fee (the
"Series 1998-1 Monthly Servicing Fee") shall be payable to the Servicer on each
Distribution Date for the preceding Settlement Period in an amount equal to the
product of (a) the Servicing Fee and (b) a fraction the numerator of which is
the daily average Aggregate Commitment Amount for such Settlement Period and the
denominator of which is the sum of (i) the Aggregate Invested Amounts (other
than the Series 1998-1 Invested Amount and the Invested Amount in respect of any
variable funding certificate of any other Outstanding Series) on the first day
of such Settlement Period and (ii) the Aggregate Commitment Amount on the first
day of such Settlement Period plus the Aggregate Commitment amount for any
variable funding certificate of any other Outstanding Series.

                                   ARTICLE VII

                             CHANGE IN CIRCUMSTANCES

            SECTION 7.1. Illegality. Notwithstanding any other provision herein,
if, after the Issuance Date, the adoption of or any change in any Requirement of
Law or in the interpretation, administration or application thereof shall make
it unlawful for any APA Bank to make or maintain its portion of the VFC
Certificateholders' Interest in any Eurodollar Tranche and such APA Bank shall
notify in writing the Funding Agent, the Trustee and the Company, then the
portion of each Eurodollar Tranche applicable to such APA Bank shall thereafter
be calculated by reference to the ABR. If any such change in the method of
calculating interest occurs on a day which is not the last day of the Eurodollar
Period with respect to any Eurodollar Tranche, the Company shall pay to the
Funding Agent for the account of such APA Bank the amounts, if any, as may be
required pursuant to Section 7.4.

            SECTION 7.2. Increased Costs. (a) If any Change in Law (except with
respect to Taxes which shall be governed by Section 7.3) shall:

                                                                              41


                  (i) impose, modify or deem applicable any reserve, special
      deposit or similar requirement against assets of, deposits with or for the
      account of, or credit extended by, any APA Bank (except any such reserve
      requirement reflected in the Eurodollar Rate); or

                  (ii) impose on any APA Bank or the London interbank market any
      other condition affecting the Transaction Documents or the funding of
      Eurodollar Tranches by such APA Bank;

and the result of any of the foregoing shall be to increase the cost to such APA
Bank of making, converting into, continuing or maintaining Eurodollar Tranches
(or maintaining its obligation to do so) or to reduce any amount received or
receivable by such APA Bank hereunder (whether principal, interest or
otherwise), then the Company will pay to such APA Bank such additional amount or
amounts as will compensate such APA Bank for such additional costs incurred or
reduction suffered.

            (b) If any APA Bank determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such APA Bank's capital or the capital of any corporation controlling such
APA Bank as a consequence of its obligations hereunder to a level below that
which such APA Bank or such corporation could have achieved but for such Change
in Law (taking into consideration such APA Bank's or such corporation's policies
with respect to capital adequacy), then from time to time, the Company shall pay
to such APA Bank such additional amount or amounts as will compensate such APA
Bank for any such reduction suffered.

            (c) A certificate of an APA Bank setting forth the amount or amounts
necessary to compensate such APA Bank as specified in subsections (a) and (b) of
this Section 7.2 shall be delivered to the Company (with a copy to the Funding
Agent) and shall be conclusive absent manifest error. The agreements in this
Section shall survive the termination of this Supplement and the Agreement and
the payment of all amounts payable hereunder and thereunder.

            (d) Failure or delay on the part of any APA Bank to demand
compensation pursuant to this Section 7.2 shall not constitute a waiver of such
APA Bank's right to demand such compensation; provided, however, that the
Company shall not be required to compensate an APA Bank pursuant to this Section
7.2 for any increased costs or reductions incurred more than 270 days prior to
the date that such APA Bank notifies the Company of the Change in Law giving
rise to such increased costs or reductions and of such APA Bank's intention to
claim compensation therefor; provided further that, if the Change in Law giving
rise to such increased costs or reductions is retroactive, then the 270-day
period referred to above shall be extended to include the period of retroactive
effect thereof.

            SECTION 7.3. Taxes. (a) Any and all payments made by the Company to
the Funding Agent or the APA Banks (including any Acquiring APA Bank) hereunder
or under the other Transaction Documents shall be made free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
excluding (i) in the case of the Funding Agent or any APA Bank, taxes that would
not be imposed but for a connection between such APA Bank or the Funding Agent
(as the case may be) and the jurisdiction imposing such tax, other than a
connection arising solely by virtue of the activities of such APA Bank or the
Funding Agent (as the case may be) pursuant to or in respect of this Agreement
or under any other Transaction Document or any transaction

                                                                              42


contemplated hereunder or thereunder; (ii) any taxes imposed on the Funding
Agent or such APA Bank as a result of payments not related to the VFC
Certificates or this Supplement; (iii) any taxes that would not have been
imposed but for the failure of the Funding Agent or such APA Bank, as
applicable, to provide and keep current to the extent required by law any
certification or other documentation required to be furnished by the Funding
Agent or such APA Bank under Subsection 7.3(f) of this Supplement; (iv) any
taxes imposed as a result of a change (other than a change mandated by law or
this Agreement) by the Funding Agent or any APA Bank of the office in which any
VFC Certificate is held, accounted for or booked; and (v) any Withholding Taxes
(as defined in Subsection 7.3(g) below) except to the extent provided in
Subsection 7.3(g) below (all such excluded taxes being referred to hereinafter
as "Excluded Taxes" and all such taxes, levies, imposts, deductions, charges,
withholdings and liabilities other than Excluded Taxes being hereinafter
referred to as "Taxes"). If any Taxes shall be required by law to be deducted
from or in respect of any sum payable hereunder or under any other Transaction
Document to any APA Bank or the Funding Agent, (i) the sum payable by the
Company shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 7.3) such APA Bank or the Funding Agent, as the case may be,
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Company shall make such deductions and (iii) the
Company shall pay the full amount deducted to the relevant taxing authority or
other authority in accordance with applicable law.

            (b) In addition, the Company agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from the execution, delivery or registration of, or
otherwise with respect to, this Agreement or any other Transaction Document
(hereinafter referred to as "Other Taxes").

            (c) The Company will indemnify each APA Bank and the Funding Agent
for the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 7.3) paid by
such APA Bank or the Funding Agent, as the case may be, and any liability
(including penalties, interest and expenses including reasonable attorney's fees
and expenses) arising therefrom or with respect thereto whether or not such
Taxes or Other Taxes were correctly or legally asserted. A certificate as to the
amount of such payment or liability prepared by a APA Bank or the Funding Agent,
absent manifest error, shall be final, conclusive and binding for all purposes,
provided that if the Company reasonably believes that such Taxes were not
correctly or legally asserted, such APA Bank or the Funding Agent, as the case
may be shall use reasonable efforts to cooperate with the Company to obtain a
refund of such Taxes or Other Taxes. Such indemnification shall be made within
10 days after the date any APA Bank or the Funding Agent, as the case may be,
makes written demand therefor. If a APA Bank or the Funding Agent shall become
aware that it is entitled to receive a refund in respect of Taxes or Other
Taxes, it shall promptly notify the Company of the availability of such refund
and shall, within 30 days after receipt of a request by the Company, pursue or
timely claim such refund at the Company's expense. If any APA Bank or the
Funding Agent receives a refund in respect of any Taxes or Other Taxes for which
such APA Bank or the Funding Agent has received payment from the Company
hereunder, it shall promptly repay such refund (plus any interest received) to
the Company (but only to the extent of indemnity payments made, or additional
amounts paid, by the Company under this Section 7.3 with respect to the Taxes or
Other Taxes giving rise to such refund), provided that the Company, upon the
request of such APA Bank or Funding Agent, agrees to return such refund (plus
any penalties, interest or other charges required to be paid) to such APA Bank
or the Funding Agent in the event such APA Bank or the Funding Agent is required
to repay such refund to the relevant

                                                                              43


taxing authority. Nothing contained herein shall require the Funding Agent or an
APA Bank (or Transferee) to make its tax returns (or any other information
relating to its taxes which it deems confidential) available to the Company or
any other Person.

            (d) Within 30 days after the date of any payment of Taxes or Other
Taxes withheld by the Company in respect of any payment to any APA Bank or the
Funding Agent, the Company will furnish to the Funding Agent at its address
referred to in Section 11.9, the original or a certified copy of a receipt
evidencing payment thereof.

            (e) Without prejudice to the survival of any other agreement
contained herein, the agreements and obligations contained in this Section 7.3
shall survive the payment in full of principal and interest hereunder and the
termination of the Trust.

            (f) The Funding Agent and each of the APA Banks (or Transferees)
agrees that, prior to the date on which the first interest payment on a VFC
Certificate is due hereunder, it will deliver to the Servicer and the Trustee
(i) if the Funding Agent or such APA Bank is not incorporated under the laws of
the United States or any State thereof (a "Non-U.S. Person"), two duly completed
copies of the United States Internal Revenue Service Form 4224 or successor
applicable or required form and (ii) an Internal Revenue Service Form W-8 or W-9
or successor applicable or required form. The Funding Agent and each APA Bank
also agrees to deliver to the Servicer and the Trustee two further copies of the
said Form 4224 and Form W-8 or W-9, or successor applicable forms or other
manner of certification, as the case may be, on or before the date that any such
form expires or becomes obsolete or after the occurrence of any event requiring
a change in the most recent form previously delivered by it to the Servicer and
the Trustee and such extensions or renewals thereof as may reasonably be
requested by the Servicer or the Trustee, unless in any such case the Funding
Agent or such APA Bank is unable to deliver any such form due to a change in law
prior to the date on which any such delivery would otherwise be required which
renders any such form inapplicable. Notwithstanding any provision of this
Supplement or the Agreement to the contrary, the Servicer and the Trustee shall
be entitled to withhold or cause such withholding, and additional amounts in
respect of Taxes need not be paid under this Section 7.03, with respect to the
Funding Agent, a APA Bank, a Participant or an Acquiring APA Bank in the event
that such Person fails to provide all of the forms and statements required
pursuant to this paragraph (f) to the Servicer and the Trustee.

            (g) None of the Trustee, the Servicer or the Company shall withhold
with respect to any payments to the Funding Agent or the APA Banks pursuant to
Section 1446 of the Code (a "Withholding Tax") unless such withholding is
required pursuant to a written determination received by the Trustee, the
Servicer or the Company from the Internal Revenue Service. Following such
determination, notwithstanding anything to the contrary in this Section 7.3,
each APA Bank or Participant which is not created or organized under the laws of
the United States or any State thereof (including the District of Columbia)
agrees that, upon written notice by the Trustee or the Company to such APA Bank
or Participant, as the case may be, that the Trustee, the Servicer or the
Company intends to withhold Withholding Tax (such determination being a
"Withholding Event"):

            (i) such APA Bank or Participant shall for tax years for which the
      APA Bank or Participant has already filed United States federal income tax
      returns (each a "Prior Tax Year") prior to proper notice of such
      Withholding Event and as a condition to the obligations of the Servicer
      and the Trustee pursuant to Subsection 7.3(a), provide (A) a signed
      Officer's Certificate of such APA Bank or Participant stating that amounts
      paid

                                                                              44


      hereunder have been included in such APA Bank's or Participant's United
      States federal income tax returns for each such Prior Tax Year, which
      certificate may be relied on by the Trustee and Company in asserting to
      the Internal Revenue Service the applicability of Section 1463 of the Code
      with respect to its liability for any Withholding Tax for each such Prior
      Tax Year and (B) provide information to the Trustee and the Company or, at
      the option of such APA Bank or Participant, to the Internal Revenue
      Service in support of the application of Section 1463 of the Code for each
      such Prior Tax Year; and

            (ii) if Section 1463 of the Code is not applicable for any prior Tax
      Year of such APA Bank or Participant because such APA Bank or Participant
      did not properly pay the United States federal income tax due on amounts
      payable on its VFC Certificates or hereunder during such Prior Tax Year,
      the APA Bank or Participant shall indemnify the Trust, the Trustee and the
      Company for any Withholding Tax (and any interest and penalties thereon)
      payable by the Trustee, the Company, the Servicer or the Trust on such
      amounts that are attributable to such Prior Tax Year and with respect to
      which such APA Bank or Participant did not properly pay such United States
      federal income tax.

            (h) Any payments made by the Company pursuant to this Section 7.3
shall be made solely from funds available to the Company which are not otherwise
required to be applied to the payment of any amounts (other than amounts payable
to the Company) pursuant to any Pooling and Servicing Agreements, shall be
non-recourse other than with respect to funds in excess of the funds needed to
make such payment, and shall not constitute a claim against the Company to the
extent that insufficient funds exist to make such payment.

            SECTION 7.4. Break Funding Payments. The Company agrees to indemnify
each APA Bank and to hold each APA Bank harmless from any loss or expense which
such APA Bank may sustain or incur as a consequence of (a) default by the
Company in making a borrowing of, conversion into or continuation of a
Eurodollar Tranche after the Company has given irrevocable notice requesting the
same in accordance with the provisions of this Supplement, or (b) default by the
Company in making any prepayment in connection with a Decrease after the Company
has given irrevocable notice thereof in accordance with the provisions of
Section 2.7 of this Supplement or (c) the making of a prepayment of a Eurodollar
Tranche prior to the termination of the Eurodollar Period for such Eurodollar
Tranche. Such indemnification may include an amount equal to the excess, if any,
of (i) the amount of interest which would have accrued on the amount so prepaid
or not so borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
the Eurodollar Period (or in the case of a failure to borrow, convert or
continue, the Eurodollar Period that would have commenced on the date of such
prepayment or of such failure) in each case at the Eurodollar Rate for such
Eurodollar Tranche provided for herein over (ii) the amount of interest (as
reasonably determined by such APA Bank) which would have accrued to such APA
Bank on such amount by placing such amount on deposit for a comparable period
with leading banks in the interbank eurodollar market; provided that any
payments made by the Company pursuant to this subsection shall be made solely
from funds available to the Company which are not otherwise required to be
applied to the payment of any amounts (other than amounts payable to the
Company) pursuant to any Pooling and Servicing Agreements, shall be non-recourse
other than with respect to funds in excess of the funds needed to make such
payment, and shall not constitute a claim against the Company to the extent that
insufficient funds exist to make such payment. This covenant shall survive the
termination of this Supplement and the Agreement and the payment of all amounts
payable hereunder and

                                                                              45


thereunder. A certificate as to any additional amounts payable pursuant to the
foregoing sentence submitted by any APA Bank to the Company shall be conclusive
absent manifest error.

            SECTION 7.5. Alternate Rate of Interest. If prior to the
commencement of any Eurodollar Period:

            (a) the Funding Agent determines (which determination shall be
      conclusive absent manifest error) that adequate and reasonable means do
      not exist for ascertaining the Eurodollar Rate for such Eurodollar Period,
      or

            (b) the Funding Agent is advised by the Majority Purchasers that the
      Eurodollar Rate for such Eurodollar Period will not adequately and fairly
      reflect the cost to such Purchasers of making or maintaining the
      Eurodollar Tranches during such Eurodollar Period,

then the Funding Agent shall forthwith give telecopy or telephonic notice
thereof to the Company, the Trustee and the Purchasers, whereupon until the
Funding Agent notifies the Company and the Trustee that the circumstances giving
rise to such notice no longer exist, the Available Pricing Amount shall not be
allocated to any Eurodollar Tranche.

            SECTION 7.6. Mitigation Obligations. (a) If any APA Bank requests
compensation under Section 7.2, or if the Company is required to pay any
additional amount to any APA Bank or any Governmental Authority for the account
of any APA Bank pursuant to Section 7.3, then such APA Bank shall use reasonable
efforts to designate a different lending office for funding or booking its
obligations under this Supplement and the Agreement or to assign its rights and
obligations hereunder to another of its offices, branches or affiliates, if, in
the judgment of such APA Bank, such designation or assignment (i) would
eliminate or reduce amounts payable pursuant to Section 7.2 or 7.3, as the case
may be, in the future and (ii) would not subject such APA Bank to any
unreimbursed cost or expense and would not otherwise be disadvantageous to such
APA Bank. The Company hereby agrees to pay all reasonable costs and expenses
incurred by any APA Bank in connection with any such designation or assignment.

            (b) If any APA Bank requests compensation under Section 7.2, or if
the Company is required to pay any additional amount to any APA Bank or any
Governmental Authority for the account of any APA Bank pursuant to Section 7.3,
or if any APA Bank defaults in its obligations hereunder, then the Company may,
at its sole expense and effort, upon notice to such APA Bank and the Funding
Agent, require such APA Bank to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in Section 11.11), all
its interests, rights and obligations under this Supplement to an assignee that
shall assume such obligations (which assignee may be another APA Bank, if an APA
Bank accepts such assignment); provided that (i) the Company shall have received
the prior written consent of the Funding Agent, which consent shall not
unreasonably be withheld, (ii) such APA Bank shall have received payment of an
amount equal to its Series 1998-1 Purchaser Invested Amount, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder, from the
assignee (to the extent of such Series 1998-1 Purchaser Invested Amount and
accrued interest and fees) or the Company (in the case of all other amounts) and
(iii) in the case of any such assignment resulting from a claim for compensation
under Section 7.2 or payments required to be made pursuant to Section 7.3, such
assignment will result in a reduction in such compensation or payments. An APA
Bank shall not be required to make any such assignment

                                                                              46


and delegation if, prior thereto, as a result of a waiver by such APA Bank or
otherwise, the circumstances entitling the Company to require such assignment
and delegation cease to apply.

            SECTION 8.1. Representations and Warranties of the Company and the
Servicer. The Company and the Servicer each hereby represents and warrants to

      require access to perform the collection and administrative functions to
      be performed by the Trustee under the Transaction Documents, except to the
      extent the Company or the Servicer, as the case may be, owns such property
      and (iii) have taken all actions reasonably requested by the Trustee in

      and employees and with their independent certified public accountants;
      provided that Funding Agent shall notify the Company or the Servicer, as
      the case may be, prior to any contact with such accountants and shall give
      the Company or the Servicer the opportunity to participate in such
      discussions;

                                                                              47


            (d) neither the Company nor the Servicer shall take any action, nor
      permit any Seller to take any action, requiring the satisfaction of the
      Rating Agency Condition pursuant to any Transaction Document without the
      prior written consent of the Majority Purchasers; and

            (e) it shall cooperate in good faith to allow the Trustee to use the

and back-up computer and other information management systems that are
reasonably satisfactory to the Funding Agent;

            (b) it shall provide to the Funding Agent, simultaneously with

Documents; and

            (c) it shall provide notice to the Funding Agent of the appointment
of a Successor Servicer pursuant to Section 6.2 of the Servicing Agreement.

            SECTION 8.4. Representations and Warranties of the APA Banks and any
Acquiring APA Bank. Each APA Bank and any Acquiring APA Bank represents,
warrants and covenants to the Company that:

            (a) it is not a trust, estate, partnership or "S Corporation"

designates and appoints the Funding Agent as the agent of such Purchaser under
this Supplement and each such Purchaser irrevocably authorizes the Funding
Agent, in such capacity, to take such action on its behalf under the provisions
of this Supplement and to exercise such powers and perform such duties as are
expressly delegated to the Funding Agent by the terms of this Supplement,
together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Supplement, the
Funding Agent shall not have any duties or responsibilities except those
expressly set forth herein, or any fiduciary relationship with any Purchaser,
and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Supplement or otherwise exist against the
Funding Agent.

            SECTION 10.2. Delegation of Duties. The Funding Agent may execute
any of its duties under this Supplement by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel (who may be counsel

Funding Agent shall not be responsible for the negligence or misconduct of any
agents or attorneys in-fact selected by it with reasonable care.

any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be

or received by the Funding Agent under or in connection with, this Supplement or
any other Transaction Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Supplement or any other
Transaction Document or for any failure of the Company to perform its
obligations hereunder or thereunder. The Funding Agent shall not be

                                                                              52


under any obligation to any Purchaser to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Supplement or any other Transaction Document, or to inspect the
properties, books or records of the Company.

            SECTION 10.4. Reliance by Funding Agent. The Funding Agent shall be
entitled to rely, and shall be fully protected in relying, upon any Certificate,
writing, resolution, notice, consent, certificate, affidavit, letter, telecopy,
telex or teletype message, statement, order or other document or conversation
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Company or the Servicer),
independent accountants and other experts selected by the Funding Agent and
shall not be liable for any action taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts. The
Funding Agent may deem and treat the payee of any Certificate as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Funding Agent. The Funding Agent
shall be fully justified in failing or refusing to take any action under this
Supplement or any other Transaction Document unless it shall first receive such
advice or concurrence of the Majority Purchasers as it deems appropriate or it
shall first be indemnified to its satisfaction by the Purchasers against any and
all liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Funding Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Supplement

Purchasers, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Purchasers.

            SECTION 10.5. Notice of Servicer Default or Early Amortization Event
or Potential Early Amortization Event. The Funding Agent shall not be deemed to
have knowledge or notice of the occurrence of any Servicer Default with respect
to the Servicer or any Early Amortization Event or Potential Early Amortization
Event hereunder unless the Funding Agent has received notice from a Purchaser,
the Company or the Servicer referring to the Agreement or this Supplement,
describing such Servicer Default or Early Amortization Event or Potential Early
Amortization Event and stating that such notice is a "notice of a Servicer
Default with respect to the Servicer" or a "notice of an Early Amortization
Event or Potential Early Amortization Event", as the case may be. In the event
that the Funding Agent receives such a notice, the Funding Agent shall give
notice thereof to the Purchasers, the Trustee, the Company and the Servicer. The
Funding Agent shall take such action with respect to such Servicer Default or
Early Amortization Event or Potential Early Amortization Event as shall be
reasonably directed by the Majority Purchasers, provided that unless and until
the Funding Agent shall have received such directions, the Funding Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Servicer Default or Early Amortization Event or
Potential Early Amortization Event as it shall deem advisable in the best
interests of the Purchasers.

            SECTION 10.6. Non-Reliance on the Funding Agent and Other
Purchasers. Each Purchaser expressly acknowledges that neither the Funding Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates has made any representations or warranties to it and that no act by
the Funding Agent hereinafter taken, including any review of the affairs of the
Company, shall be deemed to constitute any representation or warranty by the
Funding Agent to any Purchaser. Each Purchaser represents to the Funding Agent
that it has, independently and without reliance upon the Funding Agent or any
other Purchaser, and based

                                                                              53


on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Company and made its
own decision to enter into this Supplement. Each Purchaser also represents that
it will, independently and without reliance upon the Funding Agent or any other
Purchaser, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Supplement and the other
Transaction Documents, and to make such investigation as it deems necessary to
inform itself as to the business, operations, property, financial and other
condition and creditworthiness of the Company. Except for notices, reports and
other documents expressly required to be furnished to the Purchasers by the
Funding Agent hereunder, the Funding Agent shall not have any duty or
responsibility to provide any Purchaser with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of the Company which may come into the
possession of the Funding Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or Affiliates.

            SECTION 10.7. Indemnification. The Purchasers agree to indemnify the
Funding Agent in its capacity as such (to the extent not reimbursed by the
Company and the Servicer and without limiting the obligation of the Company and
the Servicer to do so), ratably according to their respective Series 1998-1
Purchaser Invested Amounts in effect on the date on which indemnification is
sought, from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time be imposed on, incurred by or asserted
against the Funding Agent in any way relating to or arising out of the
Commitments, this Supplement, any of the other Transaction Documents or any
documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the Funding
Agent under or in connection with any of the foregoing; provided that no
Purchaser shall be liable for the payment of any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting solely from the Funding Agent's gross
negligence or willful misconduct. The agreements in this Section shall survive
the payment of all amounts payable hereunder.

            SECTION 10.8. The Funding Agent in Its Individual Capacity. The
Funding Agent and its Affiliates may make loans to, accept deposits from and
generally engage in any kind of business with the Company, the Servicer or any
of their Affiliates as though the Funding Agent were not the Funding Agent
hereunder. With respect to any VFC Certificate held by the Funding Agent, the
Funding Agent shall have the same rights and powers under this Supplement and
the other Transaction Documents as any Purchaser and may exercise the same as
though it were not the Funding Agent, and the terms "APA Bank" and "Purchaser"
shall include the Funding Agent in its individual capacity.

            SECTION 10.9. Successor Funding Agent. The Funding Agent may resign
as Funding Agent upon 10 days' notice to the Purchaser and the Company, such
resignation not to be effective until a successor funding agent is appointed. If
the Funding Agent shall resign as Funding Agent under this Supplement, then the
Majority Purchasers shall appoint from among the Purchasers a successor
administrative agent for the Purchasers, which successor administrative agent
shall be approved by the Company and the Servicer (which approval shall not be
unreasonably withheld), whereupon such successor administrative agent shall
succeed to the rights, powers and duties of the Funding Agent, and the term
"Funding Agent" shall mean such successor administrative agent effective upon
such appointment and approval, and the

                                                                              54


former Funding Agent's rights, powers and duties as Funding Agent shall be
terminated, without any other or further act or deed on the part of such former
Funding Agent or any of the parties to this Supplement. After any retiring
Funding Agent's resignation as Funding Agent, the provisions of this Article 10
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Funding Agent under this Supplement.

                                   ARTICLE XI

by the Funding Agent or the Majority Purchasers more fully to effect the
purposes of this Supplement and the sale of the VFC Certificates hereunder,

subsection 2.6(c), then on each Distribution Date, the Funding Agent shall remit
in like funds to each Purchaser its applicable pro rata share (based on each
such Purchaser's Series 1998-1 Purchaser Invested Amount) of each such payment
received by the Funding Agent for the account of the Purchasers.

            SECTION 11.5. Costs and Expenses. The Company agrees to pay all
reasonable out-of-pocket costs and expenses of the Funding Agent (including,

related document; provided that any payments made by the Company pursuant to
this subsection shall be made solely from funds available to the Company which
are not otherwise required to be applied to the payment of any amounts (other
than amounts payable to the Company) pursuant to

                                                                              55


any Pooling and Servicing Agreements, shall be non-recourse other than with
respect to funds in excess of the funds needed to make such payment, and shall
not constitute a claim against the Company to the extent that insufficient
proceeds exist to make such payment.

            SECTION 11.6. No Waiver; Cumulative Remedies. No failure to exercise
and no delay in exercising, on the part of the Trustee, the Funding Agent or any
Purchaser, any right, remedy, power or privilege hereunder shall operate as a

power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges herein provided are cumulative and not

without the consent of any holder of any outstanding VFC Certificate, to cure
any ambiguity, to correct or supplement any provisions herein which may be
inconsistent with any other provisions herein or to add any other provisions to
or change in any manner or eliminate any of the provisions with respect to
matters or questions raised under this Supplement which shall not be
inconsistent with the provisions of any Pooling and Servicing Agreement;
provided, however, that such action shall not, as evidenced by an Officer's
Certificate or, to the extent in the reasonable view of the Company, a question
of law exists, an Opinion of Counsel delivered to the Trustee, adversely affect
in any material respect the interests of the VFC Certificateholders. The Trustee
may, but shall not be obligated to, enter into any such amendment pursuant to
this paragraph or paragraph (b) below which affects the Trustee's rights, duties
or immunities under any Pooling and Servicing Agreement or otherwise.

            (b) Subject to subsection (c) of this Section 11.7, this Supplement
may also be amended in writing from time to time by the Servicer, the Company
and the Trustee with the consent of the Majority Purchasers for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Supplement or of modifying in any manner the rights of the
VFC Certificateholders (including, without limitation, the acceleration of the
payment of sums payable to or for the account of the Purchasers under any
provision of this Supplement); provided, however, that no such amendment shall,
unless signed or consented to in writing by all Purchasers, (i) extend the time
for payment, or reduce the amount, of any sum payable to or for the account of
any Purchaser under any provision of this Supplement or extend the Series 1998-1
Termination Date, (ii) subject any Purchaser to any additional obligation
(including, without limitation, any change in the determination of any amount
payable by any Purchaser) or (iii) change the Aggregate Commitment Amount, the
amount of any interest or fees or the percentage of Purchasers which shall be
required for any action under this subsection or any other provision of this
Supplement.

            (c) Any amendment hereof can be effected without the Funding Agent's
being party thereto; provided, however, that no such amendment, modification or
waiver of this Supplement that affects rights or duties of the Funding Agent
shall be effective unless the Funding Agent shall have given its prior written
consent thereto.

            (d) No amendment hereof shall be effective until the Rating Agency
Condition has been satisfied (unless Series 1998-1 has not been rated, in which
case this subsection 11.7(d) shall not apply).

                                                                              56


            SECTION 11.8. Severability. If any provision hereof is void or
unenforceable in any jurisdiction, such voidness or unenforceability shall not

rights under this Supplement except as set forth in Section 2.6 and each APA

                                                                              57


Bank may not assign or transfer any of its rights under this Supplement except
as set forth in Section 11.11.

            SECTION 11.11. Participations; Assignments. (a) Any APA Bank may,
upon prior written notice to the Funding Agent and the Rating Agencies and the
satisfaction of all applicable requirements under Section 5.3 of the Agreement
and in accordance with applicable law, assign to one or more assignees (any such
assignee shall be referred to herein as an "Acquiring APA Bank") all or a
portion of its interests, rights and obligations under this Supplement and the
Transaction Documents; provided, however, that no such assignment shall be
permitted (i) except in the case of an assignment to another APA Bank, without
the Company's prior written consent to such assignment (which consent shall not
be unreasonably withheld or delayed), (ii) if such assignment is not otherwise
permitted under subsection 5.3(e) of the Agreement, (iii) if such assignment is
for any amount less than $5,000,000, (iv) if such Acquiring APA Bank is not an
Eligible Assignee, (iv) if such assignment would cause there to be more than 30
Targeted Holders of the VFC Certificates at any time, and (v) unless the parties
to each such assignment shall execute and deliver to the Funding Agent a
commitment transfer supplement (each, a "Commitment Transfer Supplement"),
substantially in the form of Exhibit C, together with a processing and
recordation fee of $3,500, and the Acquiring APA Bank, if it shall not be a APA
Bank, shall deliver to the Funding Agent an administrative questionnaire in the
form provided by the Funding Agent. Upon acceptance and recording pursuant to
paragraph (e) of this Section 11.11, from and after the effective date specified
in each Commitment Transfer Supplement, which effective date shall be at least
five Business Days after the execution thereof, (A) the Acquiring APA Bank
thereunder shall be a party hereto and, to the extent of the interest assigned
by such Commitment Transfer Supplement, have the rights and obligations of an
APA Bank under this Supplement and (B) the assigning APA Bank thereunder shall,
to the extent of the interest assigned by such Commitment Transfer Supplement,
be released from its obligations under this Supplement and the other Transaction
Documents (and, in the case of a Commitment Transfer Supplement covering all or
the remaining portion of an assigning APA Bank's rights and obligations under
this Supplement and the other Transaction Documents, such APA Bank shall cease
to be a party hereto but shall continue to be entitled to receive Article VII
Costs, as well as any fees accrued for its account and not yet paid).

            (b) By executing and delivering a Commitment Transfer Supplement,
the assigning APA Bank thereunder and the Acquiring APA Bank thereunder shall be
deemed to confirm to and agree with each other and the other parties hereto as
follows: (i) such assigning APA Bank warrants that it is the legal and
beneficial owner of the interest being assigned thereby free and clear of any
adverse claim and that its Commitment, and the outstanding balances of its VFC
Certificates, in each case without giving effect to assignments thereof which
have not become effective, are as set forth in such Commitment Transfer
Supplement; (ii) except as set forth in (i) above, such assigning APA Bank makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Supplement, or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Supplement, any other Transaction Document or any
other instrument or document furnished pursuant hereto or thereto, or the
financial condition of the Seller, the Company or the Servicer, or the
performance or observance by the Seller, the Company or the Servicer of any of
its obligations under this Supplement, any other Transaction Document or any
other instrument or document furnished pursuant hereto or thereto; (iii) such
Acquiring APA Bank represents and warrants that it is legally authorized to
enter into such Commitment Transfer Supplement; (iv) such Acquiring APA Bank
confirms that it has received a copy of this Supplement and such other documents
and information as it has deemed

                                                                              58


appropriate to make its own credit analysis and decision to enter into such
Commitment Transfer Supplement; (v) such Acquiring APA Bank will independently
and without reliance upon the Funding Agent, the Trustee, the assigning APA Bank
or any other APA Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Supplement or any other Transaction
Document; (vi) such Acquiring APA Bank appoints and authorizes the Funding Agent
and the Trustee to take such action as agent on its behalf and to exercise such
powers under this Supplement as are delegated to the Funding Agent and the
Trustee, respectively, by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vii) such Acquiring APA Bank agrees that it
will perform in accordance with their terms all the obligations which by the
terms of this Supplement are required to be performed by it as a APA Bank.

            (c) Notwithstanding and in addition to the provisions of Section 5.3
of the Agreement, the Funding Agent shall maintain at one of its offices in The
City of New York a copy of each Commitment Transfer Supplement delivered to it
and a register for the recordation of the names and addresses of the APA Banks,
and the Commitments of, and the principal amount of the VFC Certificates issued
to, each APA Bank pursuant to the terms hereof from time to time (the
"Register"). Notwithstanding the provisions of Section 5.5 of the Agreement, the
entries in the Register as provided in this subsection 11.11(c) shall be
conclusive and the Company, the Servicer, the APA Banks, the Paying Funding
Agent, the Transfer Funding Agent and Registrar, the Funding Agent and the
Trustee shall treat each person whose name is recorded in the Register pursuant
to the terms hereof as an APA Bank hereunder for all purposes of this
Supplement, notwithstanding notice to the contrary. However, in accordance with
Section 5.5 of the Agreement, in determining whether the holders of the
requisite Fractional Undivided Interests have given any request, demand,
authorization, direction, notice, consent or waiver hereunder, VFC Certificates
owned by the Company, the Servicer or any Affiliate thereof, shall be
disregarded and deemed not to be outstanding, except that, in determining
whether the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent or waiver, only VFC Certificates which
a Responsible Officer of the Trustee actually knows to be so owned shall be so
disregarded. VFC Certificates so owned by the Company, the Servicer or any
Affiliate thereof which have been pledged in good faith shall not be disregarded
and may be regarded as outstanding if the pledgee establishes to the
satisfaction of the trustee the pledgee's right so to act with respect to such
VFC Certificates and that the pledgee is not the Company, the Servicer or any
Affiliate thereof. The Register shall be available for inspection by the
Company, the Servicer, the APA Banks and the Trustee, at any reasonable time and
from time to time upon reasonable prior notice.

            (d) Upon its receipt of a copy of the written consent of the Company
(if required under Section 11.11(a) above) and a duly completed Commitment
Transfer Supplement executed by an assigning APA Bank and an Acquiring APA Bank,
an administrative questionnaire completed in respect of the Acquiring APA Bank
(unless the Acquiring APA Bank shall already be a APA Bank hereunder) and the
processing and recordation fee referred to in paragraph (a) above, the Funding
Agent shall (i) accept such Commitment Transfer Supplement, (ii) record the
information contained therein in the Register and (iii) give prompt written
notice thereof to the APA Banks, the Company, the Servicer and the Trustee. No
assignment shall be effective unless and until it has been recorded in the
Register as provided in this paragraph (d).

            (e) Any APA Bank may sell participations to one or more banks or
other entities (the "Participants") in all or a portion of its rights and
obligations under this Supplement and the other Transaction Documents (including
all or a portion of its Commitment and VFC

                                                                              59


Certificates); provided that any Participant shall, prior to entering into a
Participation, execute and deliver to the Company and the Trustee an
Assignment/Participation Certification; and provided further, that (i) such APA
Bank's obligations under this Agreement shall remain unchanged, (ii) such APA
Bank shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) the Participants shall be entitled to
receive Article VII Costs, and shall be required to provide the tax forms and
certifications described in Section 7.3(f), to the same extent as if they were
APA Banks, provided that no such Participant shall be entitled to receive any
greater amount of Article VIII Costs than an APA Bank would have been entitled
to receive in respect of the amount of the Participation sold by such APA Bank
to such Participant had no sale occurred, (iv) the Company, the Servicer, the
other APA Banks, the Funding Agent and the Trustee, shall continue to deal
solely and directly with such APA Bank in connection with such APA Bank's rights
and obligations under this Supplement, and such APA Bank shall retain the sole
right to enforce its rights under VFC Certificates and to approve any amendment,
modification or waiver of any provision of this Supplement (other than
amendments, modifications or waivers decreasing any fees payable hereunder or
the amount of principal of or the rate at which interest is payable on the VFC
Certificates, extending any scheduled principal payment date or date fixed for
the payment of interest on the VFC Certificates or increasing or extending the
Commitments) (v) the sum of the aggregate amount of any Commitment or portion
thereof subject to each such Participation plus the portion of the Series 1998-1
Invested Amount represented by an VFC Certificates subject to such Participation
shall not be less than $5,000,000 and (vi) such Participation shall not cause
there to more than 30 Targeted Holders of the VFC at any time. Each APA Bank
that grants a participation to a Non-U.S. Person pursuant to this Subsection
shall provide the Company and the Trustee with appropriately executed copies of
Internal Revenue Service Form 4224 with respect to each Participant (i) prior to
any such disposition and (ii) upon the occurrence of any event which would
require the amendment or resubmission of any such form previously provided
hereunder. No Participant may grant a subparticipation in a VFC Certificate or
this Supplement under any circumstances.

            (f) Any APA Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
11.11, disclose to the Acquiring APA Bank or Participant (each, a "Transferee")
or proposed Acquiring APA Bank or Participant any information relating to the
Seller, the Servicer, the Trust or the Company furnished to such APA Bank by or
on behalf of such entities; provided that if any such information is subject to
a confidentiality agreement between such APA Bank and the Company or the
Servicer, the Transferee or prospective Transferee shall have agreed to be bound
by the terms and conditions of such confidentiality agreement.

            (g) The Company shall not assign or delegate any of its rights or
duties hereunder other than to the Servicer without the prior written consent of
the Funding Agent, the Trustee and each APA Bank, and any attempted assignment
without such consent shall be null and void.

            (h) If, pursuant to this Supplement, any interest in this Supplement
or in a VFC Certificate is transferred to any Transferee which is a Non-U.S.
Person, the APA Bank making such transfer shall cause such Transferee,
concurrently with the effectiveness of such Transfer, (i) to furnish to the
assigning APA Bank (and, in the case of any Acquiring APA Bank, the Funding
Agent, the Company and the Trustee), with copies to the Servicer, United States
Internal Revenue Service Form 4224 (or successor applicable forms) unless a
change in law has occurred prior to the date on which such delivery would
otherwise be required which renders such form inapplicable and (ii) to agree
(for the benefit of the APA Banks, the Funding Agent,

                                                                              60


the Servicer, the Company and the Trustee) to provide the assigning APA Bank
(and, in the case of any Acquiring APA Bank, the Funding Agent, the Company and
the Trustee) a new Form 4224 (or successor applicable forms) upon the expiration
or obsolescence of any previously delivered form and comparable statements in
accordance with applicable United States laws and regulations and amendments
duly executed and completed by such Transferee unless a change in law has
occurred prior to the date on which such form inapplicable, and to comply from
time to time with all applicable United States laws and regulations with regard
to such withholding tax exemption.

            (i) Notwithstanding any other provisions herein, no transfer or
assignment of any interests or obligations of any APA Bank hereunder or any
grant of participations therein shall be permitted if such transfer, assignment
or grant would result in a prohibited transaction under Section 4975 of the
Internal Revenue Code or Section 406 of ERISA or cause the Trust Assets to be
regarded as "plan assets" pursuant to 29 C.F.R. ss. 2510.3-101, or require the
Company or the Seller to file a registration statement with the Securities and
Exchange Commission or to qualify under the "blue sky" laws of any state.


            SECTION 11.12. Adjustments; Set-off. (a) If any Purchaser (a
"Benefitted Purchaser") shall at any time receive in respect of its Series
1998-1 Invested Amount any distribution of principal, interest, Commitment Fees
or other fees, or any interest thereon, or receive any collateral in respect
thereof (whether voluntarily or involuntarily, by set-off or otherwise) in a
greater proportion than any such distribution received by any other Purchaser,
if any, in respect of such other Purchaser's Series 1998-1 Invested Amount, or
interest thereon, such Benefitted Purchaser shall purchase for cash from the
other Purchasers such portion of each such other Purchaser's interest in the VFC
Certificates, or shall provide such other Purchasers with the benefits of any
such collateral, or the proceeds thereof, as shall be necessary to cause such
Benefitted Purchaser to share the excess payment or benefits of such collateral
or proceeds ratably with each of the Purchasers; provided, however, that if all
or any portion of such excess payment or benefits is thereafter recovered from
such Benefitted Purchaser, such purchase shall be rescinded, and the purchase
price and benefits returned, to the extent of such recovery, but without
interest. The Company agrees that each Purchaser so purchasing a portion of the
VFC Certificateholders' Interest may exercise all rights of payment (including,
without limitation, rights of set-off) with respect to such portion as fully as
if such Purchaser were the direct holder of such portion.

            (b) In addition to any rights and remedies of the Purchasers
provided by law, each Purchaser shall have the right, without prior notice to
the Company, any such notice being expressly waived by the Company to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Company hereunder or under the VFC Certificates to set-off and appropriate and
apply against any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Purchaser to
or for the credit or the account of the Company. Each Purchaser agrees promptly
to notify the Company and the Funding Agent after any such set-off and
application made by such Purchaser; provided that the failure to give such
notice shall not affect the validity of such set-off and application.

            SECTION 11.13. Counterparts. This Supplement may be executed in any
number of counterparts and by the different parties hereto in separate
counterparts, each of

                                                                              61


which when so executed shall be deemed to be an original, and all of which taken
together shall constitute one and the same agreement.

            SECTION 11.14. No Bankruptcy Petition. (a) The Funding Agent and
each Purchaser hereby covenants and agrees that, prior to the date which is one
year and one day after the later of (i) the last day of the Series 1998-1
Amortization Period and (ii) the last day of the amortization period of any
other Outstanding Series, it will not institute against, or join any other
Person in instituting against, the Company any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings, or other similar proceedings
under any federal or state bankruptcy or similar law.

            (b) The Company, the Servicer, the Trustee, the Funding Agent and
each APA Bank hereby covenants and agrees that, prior to the date which is one
year and one day after the payment in full of all outstanding Commercial Paper,
it will not institute against, or join any other Person in instituting against,
the Initial Purchaser any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings, or other similar proceedings under any federal or state
bankruptcy or similar law.

            SECTION 11.15. Limitation on Addition and Termination of Sellers.
(a) Notwithstanding anything to the contrary contained in the Receivables Sale
Agreements, no Seller or Seller Division shall be added thereunder unless each
of the following conditions shall have been satisfied:

            (i) (x) in the case of a proposed addition of a Seller, each of the
      conditions set forth in Section 3.02 of each of the Receivables Sale
      Agreements, and (y) in the case of a proposed addition of a Seller
      Division, the conditions set forth in subsections (c), (g), (h), (i), (j),
      (k) and (l) (in each case, applied to the applicable New Division as if it
      were a proposed additional Seller) of Section 3.02 of each of the
      Receivables Sale Agreements, shall have been satisfied.

            (ii) The Company shall have received copies of the Policies of such
      additional Seller (or such Seller Division, as the case may be, if
      different from the Policies of the Seller of which it is a New Division),
      which Policies shall be in form and substance satisfactory to the Company.

            (iii) The Company shall have received confirmation (A) that there is
      no pending or, to its knowledge after due inquiry, threatened action or
      proceeding affecting such additional Seller (or such Seller Division, as
      the case may be) before any Governmental Authority (I) that could
      reasonably be expected to have a Material Adverse Effect or (II) that
      purports to affect the legality, validity or enforceability of this
      Supplement, the Agreement or any other Transaction Document or any of the
      transactions contemplated hereby or thereby.

            (iv) The Company and the Trustee shall have received evidence that
      the Rating Agency Condition shall have been satisfied with respect to the
      addition of such Seller (or addition of such Seller Division, as the case
      may be); provided that such satisfaction of the Rating Agency Condition
      (and such receipt of evidence thereof) shall not be required with respect
      to the addition of up to three Subsidiaries of WESCO (and/or New
      Divisions) as Sellers (or Seller Divisions) during any calendar year, each
      of which Subsidiaries (or New Divisions) meets the following criteria: (x)
      such Subsidiary

                                                                              62


      (or New Division) is in the same line of business as the existing Sellers
      as of the related Seller Addition Date (as defined in the Receivables Sale
      Agreements) and (y) as of such date, immediately prior to giving effect to
      such addition (the "Measurement Date"), the ratio (expressed as a
      percentage) of (A) the aggregate Principal Amount of what would constitute
      all Eligible Receivables of such Subsidiary (or New Division) at the end
      of the Business Day immediately preceding the Measurement Date if it were
      a Seller (or Seller Division) minus the amount which would constitute the
      Overconcentration Amount applicable to such Receivables on the Measurement
      Date if such Subsidiary (or New Division) were a Seller (or Seller
      Division) to (B) the sum of the Aggregate Receivables Amount as of the end
      of such day plus the amount described pursuant to clause (A) is less than
      10 percent.

            (v) The Trustee shall have received Opinions of Counsel of outside
      counsel addressed to the Trustee covering matters with respect to such
      Seller as were covered in the opinions delivered on the Issuance Date with
      respect to the original Sellers, including "true-sale" and non-substantive
      consolidation opinions (only in the case of the addition of an Additional
      Seller).

            (vi) The Company and the Trustee shall have received a certificate
      prepared by a Responsible Officer of the Servicer certifying that after
      giving effect to the addition of such Seller (or such Seller Division, as
      the case may be), the Aggregate Target Receivables Amount shall equal the
      Aggregate Allocated Receivables Amount on the related Seller Addition
      Date.

            (b) Notwithstanding anything to the contrary contained in the
Receivables Sale Agreements, the Company shall not consent to any request made
pursuant to Section 9.13 thereof, nor shall any Seller which is the subject of
such request be terminated under the Receivables Sale Agreements, in each case
unless (i) no Early Amortization Event, Potential Early Amortization Event or
Potential Purchase Termination Event (as defined in the Receivables Sale
Agreements) (other than with respect to the Seller to be so terminated) has
occurred and is continuing (both before and after giving effect to such
termination) and (ii) the Trustee shall have received prior notice of such
termination (which notice shall be accompanied by a pro forma Daily Report
confirming that the Aggregate Target Receivables Amount equals or exceeds the
Aggregate Allocated Receivables Amount, each calculated after giving effect to
