         NALCO COMPANY, a Delaware corporation ("Nalco Company") and NALCO

RECEIVABLES LLC, a Delaware limited liability company (the "Buyer"), agree as
follows:

                             PRELIMINARY STATEMENTS.

          (3) The Sellers and the Buyer intend that the transfer of the

ownership of the Receivables and the Receivables Property;

          (4) To obtain the necessary funds to purchase the Receivables

Agent in respect of the Purchased Receivables, and each Seller has been

           NOW, THEREFORE, in consideration of the premises and of the

         ARTICLE II. AMOUNTS AND TERMS OF PURCHASES

         SECTION 2.01. Agreement to Purchase. (a) Upon the terms and subject to
the conditions hereof, each Seller hereby sells, assigns, transfers and conveys
to the Buyer, without recourse (except to the limited extent provided herein),
all its respective present and future right, title and interest in, to and
under:

              (i) all Receivables existing on the Closing Date with respect to
    such Seller and thereafter arising from time to time until the Termination
    Date with respect to such Seller;

              (ii) all Collections with respect thereto; and

              (iii) all Related Security with respect thereto

(the property described in the foregoing clauses (ii) and (iii) are hereinafter
collectively referred to as the "Receivables Property"). Subject to the terms
and conditions set forth herein, the Buyer hereby agrees to purchase the
Receivables and Receivables Property of each Seller from time to time until the
Termination Date with respect to such Seller.

         (b) On the Closing Date and on the date of creation of each newly
arising Receivable, all of such Seller's right, title and interest in, to and
under (i) in the case of the Closing Date, all then existing Receivables and all
Receivables Property with respect thereto and (ii) in the case of each such date
of creation (but only so long as the Termination Date has not occurred with
respect to such Seller), all such newly created Receivables and all Receivables
Property with respect thereto shall be immediately and automatically sold,
assigned, transferred and conveyed to the Buyer pursuant to Section 2.01(a)
above without any further action by such Seller or any other Person. If any
Seller shall not have received payment from the Buyer of the Purchase Price for
any Purchased Receivable and the related Receivables Property on the Purchase
Date therefor in accordance with the terms of and by the time specified in
Section 2.02(c) (a "Non-Payment Event"), whether or not the conditions set forth
in Article III have been fulfilled, such Purchased Receivable and the
Receivables Property with respect thereto shall, upon receipt of notice from
such Seller of such failure to receive payment (which notice shall be provided
only on the applicable Purchase Date and may not be delivered at any time
thereafter), immediately and automatically be sold, assigned, transferred and
reconveyed by the Buyer to such Seller without any further action by the Buyer
or any other Person.

         (c) It is the intention of the parties hereto that each Purchase of
Receivables made hereunder shall be treated as a purchase by the Buyer and a
sale by the applicable Seller of such Receivables and the Receivables Property
with respect thereto, which sales are absolute and

                                       6


irrevocable and provide the Buyer with the full benefits of ownership of the
Receivables. Each sale of Receivables hereunder is made without recourse to the
applicable Seller; provided, however, that (i) each Seller shall be liable to
the Buyer for all representations, warranties, covenants and indemnities made by
such Seller pursuant to the terms of this Agreement, and (ii) such sale does not
constitute and is not intended to result in an assumption by the Buyer or any
assignee thereof of any obligation of any Seller or any other Person arising in
connection with the Receivables or Receivables Property or any other obligations
of any Seller.

         (d) In connection with the foregoing sale, each Seller hereby
authorizes Buyer and its assigns to record and file from time to time, at such
Seller's expense, a financing statement or statements with respect to (i) the
Receivables sold or to be sold by such Seller hereunder and (ii) the Receivables
Property with respect thereto, in each case meeting the requirements of
applicable state law in such manner and in such jurisdictions as are necessary
to perfect and protect the interests of the Buyer created hereby under the UCC
against all creditors of such Seller. In addition, each Seller agrees that from
time to time, at its expense, it will promptly, upon request, execute and
deliver all further instruments and documents, and take all further actions that
the Buyer or the Administrative Agent may reasonably request, in order to
perfect, protect or more fully evidence the purchase by the Buyer of the
Receivables and the Receivables Property with respect thereto, an interest in
which may be perfected by filing a financing statement under the UCC. In view of
the intention of the parties hereto that the Purchases of Receivables made
hereunder shall constitute sales of such Receivables rather than a loan secured
by such Receivables, each Seller agrees, at its own expense, on or prior to the
Closing Date, to (i) indicate clearly and unambiguously in its computer files
that all Receivables and all Receivables Property with respect thereto have been
or will be conveyed to the Buyer pursuant to this Agreement and (ii) note in its
accounting records that the Receivables have been sold to the Buyer.

         SECTION 2.02. Payment for the Purchases. (a) The Purchase Price for
each Purchase from a Seller shall be payable in full by the Buyer to such Seller
or its designee on each Purchase Date and shall be paid to such Seller in the
manner provided in this Article II; provided that for purposes of the Purchase
Date occurring on the Closing Date, the Purchase Price for the Receivables and
the Receivables Property existing on the Closing Date shall be based on the
Receivables of each Seller existing as of the Cut-Off Date (the "Initial
Effective Date Purchase Price"). On the first Settlement Date occurring after
the Closing Date (the "Initial Settlement Date"), each Seller shall determine
the Purchase Price for the Receivables and Receivables Property existing on the
Closing Date based on the Receivables existing on the Closing Date (the "Actual
Effective Date Purchase Price"). If the Initial Effective Date Purchase Price
paid by the Buyer on the Closing Date is greater than the Actual Effective Date
Purchase Price with respect to any Seller, such Seller shall pay to the Buyer an
amount equal to such excess on the Initial Settlement Date. If the Initial
Effective Date Purchase Price paid by the Buyer on the Closing Date is less than
the Actual Effective Date Purchase Price with respect to any Seller, the Buyer
shall pay to such Seller an amount equal to such difference on the Initial
Settlement Date by increasing the outstanding principal amount of the
Intercompany Note for the account of such Seller in the amount of the
difference.

         (b) Upon the fulfillment of the conditions set forth in Article III,
the Purchase Price for Receivables shall be paid or provided for (without
duplication) by the Buyer in the

                                       7


manner provided in Section 2.02(c) below on the date of the initial Purchase
from the applicable Seller and on each Purchase Date thereafter until the
Termination Date with respect to such Seller.

         (c) The Purchase Price for Receivables shall be paid by the Buyer on
each Purchase Date (including the initial Purchase Date) as follows:

              (i) by netting the amount of any Purchase Price Credits pursuant
    to Section 2.03 against such Purchase Price;

              (ii) to the extent available for such purpose (as determined by
    the Buyer), in cash; and

              (iii) by means of an addition to the principal amount of the
    Intercompany Note in an aggregate amount up to the remaining portion of the
    Purchase Price. Any such addition to the principal amount of the
    Intercompany Note shall be allocated among the Sellers (pro rata according
    to the aggregate Outstanding Balances of the Receivables sold by each
    Seller) by the Seller Agent in accordance with the provisions of this
    Section 2.02(c)(iii) and Section 2.08. The Seller Agent may evidence such
    additional principal amounts by recording the date and amount thereof on the
    grid attached to the Intercompany Note; provided, however, that the failure
    to make any such recordation or any error in such grid shall not adversely
    affect any Seller's rights.

Notwithstanding the foregoing, the parties hereto agree that an amount of the
Purchase Price payable to Nalco Company equal to $50,000,000 shall be deemed to
be a contribution of capital by Nalco Company to the Buyer and the balance of
the Purchase Price shall be paid or provided for as set forth above in this
Section 2.02(c).

         (d) The Seller Agent shall be responsible, in accordance with Section
2.02(a), for allocating among the Sellers the payment of the Purchase Price for
Receivables and any amounts netted therefrom pursuant to Section 2.02(c)(i) or
credited to the Seller Agent pursuant to Section 2.02(c)(ii) or in the form of
cash to be paid pursuant to Sections 2.02(c)(ii) or in the form of an addition
to the principal amount of the Intercompany Note pursuant to Section
2.02(c)(iii). All amounts payable by the Buyer in respect of the Purchase Price
of Receivables shall be paid by the Buyer to an account of the Seller Agent for
allocation by the Seller Agent to the respective Sellers (ratably in accordance
with the portion of such Purchase Price owing to each). Each of the Sellers
hereby appoints the Seller Agent as its agent for purposes of receiving such
payments, making such allocations and taking any other actions hereunder on its
behalf and hereby authorizes the Buyer to make all payments due to such Seller
directly to, or as directed by, the Seller Agent. The Seller Agent hereby
accepts and agrees to such appointment. Any such payment by the Buyer to or at
the direction of the Seller Agent shall constitute a full and complete discharge
of the Buyer's liability for the amounts so paid, whether or not the proceeds of
such payment are properly distributed by the Seller Agent to the applicable
Seller for whose account such payment was made.

         (e) Prior to the date on which the Collection Agent must prepare and
deliver any report pursuant to Section 2.11 of the Receivables Transfer
Agreement, each Seller and the

                                       8


Buyer will make available to the Collection Agent all information necessary for
the preparation of such report including, without limitation, (i) information
regarding all Purchases and Purchase Price Credits occurring during the calendar
month (or week or day, as applicable) to be covered in such report, (ii) the
aggregate original Outstanding Balance of the Receivables sold by such Seller
during such calendar month (or week or day, if applicable), the aggregate
Purchase Price for such Receivables sold by such Seller and the components of
payment as provided in Section 2.02(c) above and in connection therewith, the
Buyer and such Seller shall, after giving effect to the application of payments
provided in Sections 2.02(c) and 2.04(b) in respect of such calendar month (or
week or day, if applicable) reconcile the amounts owed to each other in respect
of that period as provided in Section 2.04(c).

         SECTION 2.03. Purchase Price Credit Adjustments. If on any day (i) any
Receivable originated by a Seller becomes a Diluted Receivable, or (ii) any of
the representations or warranties set forth in this Agreement is not true with
respect to any Purchased Receivable or the Buyer's interest therein, then, in
such event, the Buyer shall be entitled to a credit (a "Purchase Price Credit")
against the Purchase Price otherwise payable to such Seller hereunder in respect
of thereafter created Purchased Receivables equal to the full amount of such
Diluted Receivable (in the case of clause (i) above) or equal to the Outstanding
Balance of the applicable Purchased Receivable (in the case of clause (ii)
above); provided that no Purchase Price Credit shall be granted or paid by a
Seller in the case of clause (ii) above unless requested by the Buyer (which
request must be made within six (6) months following the date the Buyer receives
notice of such breach from the applicable Seller). If the aggregate Purchase
Price Credits in respect of any Seller exceeds the Purchase Price in respect of
the Receivables of such Seller payable on any Purchase Date, or if the
Termination Date has occurred, then such Seller agrees to pay the remaining
amount of such Purchase Price Credit to the Buyer in cash on or prior to the
first Settlement Date to occur after the date on which such Purchase Price
Credit arises. Simultaneously with the granting or payment of any Purchase Price
Credit by any Seller in respect of a Purchased Receivable under clause (ii)
above, such Purchased Receivable and the Receivables Property with respect
thereto shall immediately and automatically be sold, assigned, transferred and
reconveyed (without recourse) by the Buyer to such Seller without any further
action by the Buyer or any other Person.

         SECTION 2.04. Payments and Computations, Etc. (a) All amounts to be
paid or deposited by the Buyer hereunder shall be paid or deposited in
accordance with the terms hereof by no later than 12:00 noon (New York time) on
the day when due in immediately available funds to the account of the Seller
Agent designated from time to time by the Seller Agent or as otherwise directed
by the Seller Agent. All amounts to be paid or deposited by any Seller hereunder
shall be paid or deposited in accordance with the terms hereof by no later than
11:00 A.M. (New York time) on the day when due in immediately available funds to
the account of the Buyer designated from time to time by the Buyer or as
otherwise directed by the Buyer. All payments hereunder shall be made solely in
Dollars unless otherwise specified herein. In the event that any payment owed by
any Person hereunder becomes due on a day which is not a Business Day, such
payment shall be made on the next succeeding Business Day and such extension of
time shall be included in the computation of such payment. Each Seller shall, to
the extent permitted by law, pay interest on any amount not paid or deposited by
such Seller when due, at an interest rate equal to 2.0% per annum above the Base
Rate, payable on demand. The Buyer shall, to the extent permitted by law, pay
interest on any amount not paid or deposited by

                                       9


the Buyer when due hereunder at an interest rate equal to 2.0% per annum above
the Base Rate, payable on demand provided, however, that any payments to be made
by the Buyer in respect of the foregoing shall be made solely from funds
available to the Buyer which are not otherwise required to be applied or
set-aside for the payment of any obligations of the Buyer under the Receivables
Transfer Agreement, shall be non-recourse other than with respect to such funds
and shall not constitute a claim against the Buyer to the extent that
insufficient funds exist to make such payment. All computations of interest
payable hereunder shall be made on the basis of a year of 365 (or 366, as
applicable) days for the actual number of days (including the first but
excluding the last day) elapsed.

         (b) Each Seller hereby agrees that the Seller Agent, shall be
authorized to receive amounts from the Buyer on behalf of the Sellers hereunder.
All amounts so received shall be applied in the following order of payment
during each calendar week and prior to the first Settlement Date to occur after
such week:

              (x) first, to pay any amounts payable pursuant to 2.02(c)(ii);

              (y) second, to make payments of interest on, and then principal of
              the Intercompany Note in accordance with Section 2.07 and the
              Intercompany Note; and

              (z) third, in such manner as the Buyer may specify.

         (c) On each Settlement Date:

              (i) the Seller Agent shall determine the aggregate Purchase Price
    (the "Aggregate Purchase Price") for all Receivables and Receivables
    Property conveyed by the Sellers to the Buyer during the preceding calendar
    week or, in the case of the Termination Date, during the period from the end
    of the preceding calendar week to the Termination Date (each such period, a
    "Purchase Settlement Period"); provided, that the final Purchase Settlement
    Period shall commence on the day following the most recently ended Purchase
    Settlement Period and shall end on the Termination Date;

              (ii) if on any Settlement Date, the Aggregate Purchase Price for
    the related Purchase Settlement Period minus the aggregate amount of
    Purchase Price Credits for such Purchase Settlement Period (such difference,
    the "Modified Aggregate Purchase Price") exceeds the amount of Collections
    and other cash payments received by the Seller Agent on behalf of the
    Sellers as provided herein for such Purchase Settlement Period (such amount,
    the "Cash Payments"), the Seller Agent shall, subject to the terms of this
    Agreement and to the extent it has not already done so, record the increase
    in the principal amount outstanding under the Intercompany Note up to the
    amount of such excess, and if any excess remains after giving effect to the
    increase in the principal amount of the Intercompany Note, the Sellers may
    declare the Termination Date to have occurred with respect to all Sellers by
    delivering notice to that effect to the Buyer and the Administrative Agent;

              (iii) if on any Settlement Date, the Cash Payments for the related
    Purchase Settlement Period exceed the Modified Aggregate Purchase Price for
    such

                                       10


    Purchase Settlement Period, the Seller Agent shall, subject to the terms of
    this Agreement, record the application of that excess, (x) first, to the
    payment of unpaid and accrued interest on the Intercompany Note, as
    applicable, (y) second, as a reduction in the principal amount of the
    Intercompany Note, as applicable, and, (z) third, in such other manner as
    the Buyer may specify.

         SECTION 2.05. Transfer of Records. (a) In connection with the Purchases
of Receivables hereunder, each Seller hereby sells, transfers, assigns and
otherwise conveys to the Buyer all of such Seller's right and title to and
interest in all documents, books, records and other information (including,
without limitation, computer programs, tapes, disks, punch cards, data
processing software and related property and rights) relating to the Receivables
(collectively, the "Records"), without the need for any further documentation in
connection with any Purchase hereunder. In connection with such transfer, each
Seller hereby grants to each of the Buyer and its assigns and the Collection
Agent an irrevocable, non-exclusive license (subject to the restrictions
contained in any license with respect thereto) to use, without royalty or
payment of any kind, all computer software and programs used by such Seller to
account for the Receivables, to the extent necessary or desirable to administer
or service the Receivables, whether such software and programs are owned by such
Seller or are owned by others and used by such Seller under license agreements
with respect thereto; provided, that should the consent of any licensor of such
Seller to such grant of the license described herein be required, such Seller
hereby agrees that upon the request of the Buyer or the Collection Agent to use
its best efforts to obtain the consent of such third-party licensor. The license
granted hereby shall be irrevocable, and shall not terminate until the date on
which all Purchased Receivables have been collected or written off. To the
extent that direct on-line access by the Buyer or the Collection Agent to the
computer programs and software subject to license agreements would require
additional payments for access thereto by the Buyer or the Collection Agent or
is prohibited by such license agreements and Nalco Company is no longer the
Collection Agent, such Seller hereby agrees to download, prepare and distribute,
promptly and effectively, all data relating to the Receivables in usable form as
reasonably requested by the Buyer and/or the Collection Agent from time to time.
If any Seller fails to produce such data in a prompt and effective manner, the
Buyer and the Collection Agent may have access to programs and software to
create such records, then such Seller shall incur and pay such additional
license costs and expenses with respect to the granting of such access. In
recognition of needs of the Sellers to have access to the Records which have
been transferred to the Buyer hereunder, whether as a result of its continuing
business relationship with any Obligor for Purchased Receivables or as a result
of its responsibilities as a Collection Agent or Sub-Collection Agent, the Buyer
hereby grants to each Seller an irrevocable license to access the Records
transferred by such Seller to the Buyer and to access any such transferred
computer software and programs in connection with any activity arising in the
ordinary course of such Seller's business or in performance of such Seller's
duties as a Collection Agent or Sub-Collection Agent, provided, however, that
none of the Sellers shall disrupt or otherwise interfere with the Buyer's or the
Collection Agent's use of and access to the Records and its computer software
and programs during such license period.

         (b) Each Seller shall take such action requested by the Buyer and/or
any of the Buyer's assignees, from time to time hereafter, that may be necessary
to ensure that the Buyer and its assigns have an enforceable ownership interest
in the Records relating to the Purchased Receivables purchased from such Seller
hereunder.

                                       11


         SECTION 2.06. Characterization; Grant of Security Interest. If,
notwithstanding the intention of the parties expressed in Section 2.01(c), the
conveyance by any Seller to the Buyer of Receivables hereunder shall be
characterized as a secured loan and not a sale, this Agreement shall constitute
a security agreement under applicable law. For this purpose, each Seller hereby
grants to the Buyer a security interest in all of such Seller's right, title and
interest, whether now owned or hereafter acquired, in, to and under all
Receivables and the Receivables Property with respect thereto, which security
interest shall secure all obligations of such Seller hereunder. After any
Termination Event, the Buyer and its assignees shall have, in addition to the
rights and remedies which they may have under this Agreement, all other rights
and remedies against the Sellers provided to a secured party after default in a
transaction which is a sale of accounts under the UCC and other applicable Law,
which rights and remedies shall be cumulative.

         SECTION 2.07. No Repurchase. Except to the extent expressly set forth
herein, no Seller shall have any right or obligation under this Agreement, by
implication or otherwise, to repurchase from the Buyer any Purchased Receivables
or to rescind or otherwise retroactively affect any Purchase of any Purchased
Receivable after it is sold to the Buyer hereunder.

         SECTION 2.08. Intercompany Note. (a) On the date of the initial
Purchase, the Buyer shall issue to the Seller Agent, for the account of the
Sellers as their respective interests may appear, a note substantially in the
form of Exhibit B (as amended, supplemented or otherwise modified from time to
time, the "Intercompany Note"). The aggregate principal amount of the
Intercompany Note at any time shall be equal to the difference between (i) the
aggregate principal amount on the issuance thereof and each addition to the
principal amount of the Intercompany Note with respect to each Seller pursuant
to the terms of Section 2.02(c)(iii) and Section 2.04 as of such time, minus
(ii) the aggregate amount of all payments made in respect of the principal of
the Intercompany Note as of such time. All payments made in respect of the
Intercompany Note shall be allocated, first, to pay accrued and unpaid interest
thereon, and second, to pay the outstanding principal amount thereof. Interest
on the outstanding principal amount of the Intercompany Note shall accrue at a
rate per annum equal to the Base Rate in effect from time to time from and
including the date of the initial Purchase to but excluding the last day of each
Purchase Settlement Period and shall, subject to the terms and conditions hereof
and thereof, be paid (x) on each Settlement Date with respect to the principal
amount of the Intercompany Note outstanding from time to time during the
Purchase Settlement Period immediately preceding such Settlement Date (but only
to the extent the Buyer has funds available to make such payment) and/or (y) on
the maturity date thereof; provided, however, that, to the maximum extent
permitted by law, accrued interest on the Intercompany Note which is not so paid
shall be added, at the request of the Seller Agent, to the principal amount of
the Intercompany Note. Upon receipt of any such payment, the Seller Agent shall
distribute such payment to the Sellers ratably based on their respective
interests in the Intercompany Note as described in Section 2.08(b). Principal of
the Intercompany Note not paid or prepaid pursuant to the terms thereof shall be
payable on the maturity date thereof. Notwithstanding anything to the contrary
contained in this Agreement, any payments to be made by the Buyer in respect of
the Intercompany Note shall be made solely from funds available to the Buyer
which are not otherwise required to be applied or set-aside for the payment of
any obligations of the Buyer under the Receivables Transfer Agreement, shall be
non-recourse other than with respect to such

                                       12


funds and shall not constitute a claim against the Buyer to the extent that
insufficient funds exist to make such payment.

         (b) Each addition to the principal amount of the Intercompany Note on
any Purchase Date pursuant to Section 2.02(c) above (including on the date of
the initial Purchase hereunder) shall be allocated among the Sellers by the
Seller Agent ratably in proportion to the Purchase Price owing to each on such
Purchase Date.

         (c) Anything herein to the contrary notwithstanding, the Buyer may not
make any payment of any Purchase Price on any Purchase Date by increasing the
aggregate principal amount of the Intercompany Note outstanding unless the
aggregate principal amount of the Intercompany Note outstanding on such Purchase
Date (after giving effect to all repayments thereof on or before such Purchase
Date) would not exceed 25% of the aggregate Outstanding Balance of the Purchased
Receivables on such Purchase Date.

         SECTION 2.09. Certain Allocations. Each Seller and the Buyer hereby
agree that, unless otherwise required by applicable Law or unless an Obligor
designates that a payment be applied to a specific Receivable, all Collections
from an Obligor shall be applied to the oldest Receivables (whether or not such
Receivables are Purchased Receivables) of such Obligor.

         SECTION 4.01. Representations and Warranties of the Sellers. Each
Seller represents and warrants with respect to such Seller as follows:

    the nature of its business requires it to be so qualified, unless the
    failure to so qualify could not reasonably be expected to have a Material
    Adverse Effect.

         (b) The execution, delivery and performance by such Seller of the
    Transaction Documents to which it is a party, including such Seller's sale
    of Receivables hereunder and such Seller's use of the proceeds of Purchases,

    bankruptcy, insolvency, moratorium, reorganization or other similar laws
    affecting creditors' rights generally, (ii) general principles of equity
    (regardless of whether such enforceability is considered in a proceeding in
    equity or at law) and (iii) implied covenants of good faith and fair
    dealing.

         (e) Since December 31, 2003, no Material Adverse Effect has occurred.

         (f) Except as set forth on Schedule II, (i) as of the initial Purchase
    Date, there are no actions, suits or proceedings at law or in equity or by
    or before any Official Body or in arbitration now pending or, to the actual
    knowledge of a Responsible Officer of such Seller, threatened in writing
    against or affecting such Seller or any of its business, property or rights
    and (ii) as of each Reporting Date, there are no actions, suits or
    proceedings at law or in equity or by or before any Official Body or in
    arbitration or, to the actual knowledge of a Responsible Officer of such
    Seller, threatened in writing against or affecting such Seller or any of its
    business, property or rights, which could reasonably be expected to have,
    individually or in the aggregate, a Material Adverse Effect.

         (g) No proceeds of any Purchase will be used to purchase or carry, or
    to extend credit to others for the purpose of purchasing or carrying,
    "margin stock" within the meaning of Regulation T, U or X promulgated by the
    Board of Governors of the Federal Reserve System from time to time.

         (h) No transaction contemplated hereby requires compliance with any
    bulk sales act or similar law.

         (i) Immediately prior to each Purchase of Receivables from such Seller
    hereunder, such Seller will be the owner of such Receivables and all
    Receivables Property with respect thereto, free and clear of any Adverse
    Claim. Upon each Purchase, the Buyer shall have acquired a valid and
    perfected ownership interest in each Receivable now existing or hereafter
    arising and in the Receivables Property with respect thereto, in each case
    free and clear of any Adverse Claim (other than Adverse Claims created by
    the Buyer or its assigns).

                                       16


         (j) Each report delivered pursuant to Section 2.11 of the Receivables
    Transfer Agreement (if prepared by any Seller or any of their respective
    Affiliates, or to the extent that information contained therein is supplied
    by any Seller or an Affiliate), information, exhibit, document, book, record
    or report furnished in writing at any time by or on behalf of any Seller in
    connection with the Transaction Documents is accurate in all material
    respects as of its date or (except as otherwise disclosed to the Buyer at
    such time) as of the date so furnished.

         (k) Such Seller is located in its jurisdiction of incorporation or
    organization specified in Exhibit C for the purposes of Section 9-307 of the
    UCC as in effect in the State of New York.

         (l) The names and addresses of all the Lock-Box Banks, together with
    the account numbers of the Lock-Box Accounts, are as specified in Exhibit A
    (as the same may be updated from time to time pursuant to Section 5.01(g)).

         (m) In the past five (5) years, such Seller has not used any corporate
    name, tradename or doing-business-as name other than the name in which it
    has executed this Agreement and the other names listed on Exhibit C. Such
    Seller's Federal Employer Identification Number and, if organized in a
    jurisdiction other than Delaware, its organizational identification number
    is as set forth on Exhibit C.

         (n) Such Seller is not an "investment company" as defined in, or
    subject to regulation under, the Investment Company Act of 1940, as amended.

         (o) (i) The fair value of the assets of such Seller, at a fair
    valuation, exceed the debts and liabilities, direct, subordinated,
    contingent or otherwise, of such Seller; (ii) the present fair saleable
    value of the property of such Seller is greater than the amount that will be
    required to pay the probable liability of such Seller on its debts and other
    liabilities, direct, subordinated, contingent or otherwise, as such debts
    and other liabilities become absolute and matured; (iii) such Seller will be
    able to pay its debts and liabilities, direct, subordinated, contingent or
    otherwise, as such debts and liabilities become absolute and matured; and
    (iv) such Seller does not have unreasonably small capital with which to
    conduct the businesses in which it is engaged as such businesses are now
    conducted and are proposed to be conducted following the Closing Date.

         (p) Each Receivable treated as or represented by such Seller to be an
    Eligible Receivable as of any Purchase Date was an Eligible Receivable on
    such date.

         (q) All Obligors with respect to Receivables sold by such Seller
    hereunder have been instructed to remit all their payments in respect of
    Receivables directly to a Lock-Box Account.

         (r) The transfers of Receivables by such Seller to the Buyer pursuant
    to this Agreement, and all other transactions between such Seller and the
    Buyer, have been and will be made in good faith and without intent to
    hinder, delay or defraud creditors of such Seller.

                                       17


         (s) Each Seller and its ERISA Affiliates are in compliance with the
    applicable provisions of ERISA and the provisions of the Code relating to
    Plans and the regulations and published interpretations thereunder and any
    similar applicable non-U.S. law, except for such noncompliance that could
    not reasonably be expected to have a Material Adverse Effect. No Reportable
    Event has occurred during the past five years as to which such Seller or any
    ERISA Affiliate was required to file a report with the Pension Benefit
    Guaranty Corporation, other than reports that have been filed and reports
    the failure of which to file could not reasonably be expected to have a
    Material Adverse Effect. As of the Closing Date, the present value of all
    benefit liabilities under each Plan of such Seller and the ERISA Affiliates
    (based on those assumptions used to fund such Plan), did not as of the last
    annual valuation date applicable thereto for which a valuation is available,
    exceed the value of the assets of such Plan by an amount that could
    reasonably be expected to have a Material Adverse Effect and the present
    value of all benefit liabilities of all underfunded Plans (on a termination
    basis and based on those assumptions used to fund each such Plan), did not
    as of the last annual valuation dates applicable thereto for which
    valuations are available, exceed the value of the assets of all such
    underfunded Plans by an amount that could reasonably be expected to have a
    Material Adverse Effect. None of such Seller and the ERISA Affiliates has
    incurred or could reasonably be expected to incur any Withdrawal Liability
    that could reasonably be expected to have a Material Adverse Effect. None of
    such Seller and the ERISA Affiliates has received any written notification
    that any Multiemployer Plan is in reorganization or has been terminated
    within the meaning of Title IV of ERISA, or has knowledge that any
    Multiemployer Plan is reasonably expected to be in reorganization or to be
    terminated, where such reorganization or termination has had or could
    reasonably be expected to have, through increases in the contributions
    required to be made to such Plan or otherwise, a Material Adverse Effect.

         (t) No event has occurred and is continuing and no condition exists
    which constitutes a Termination Event.

         (u) Except as set forth on Schedule III, such Seller has filed or
    caused to be filed all material tax returns and has paid or caused to be
    paid or made adequate provision for all material taxes due and payable by it
    and all material assessments received by it except to the extent that
    non-payment: (i) is being contested in good faith; or (ii) could not
    reasonably be expected to result in a Material Adverse Effect.

         (v) The assignment of each Receivable and the related Receivables
    Property the subject of any Purchase on the related Purchase Date and the
    fulfillment of the terms hereof will not violate any applicable Law or any
    material contractual obligation by which such Seller or any of its property
    may be bound.

         (w) Such Seller has performed and complied in all respects with the
    terms of the Contract relating to each Purchased Receivable that is treated
    as or represented by such Seller or any of its Affiliates to be an Eligible
    Receivable, except to the extent that such failure to comply could not
    reasonably be expected to have a Material Adverse Effect.

                                       18


         (x) Such Seller and the Collection Agent have the capability: (i) at
    any given time to identify each individual Purchased Receivable and (ii) to
    track Collections in respect of each such Receivable and each of the
    Receivables that have been or will be sold by such Seller to the Buyer in
    accordance herewith.

         (y) Such Seller has complied in all material respects with its Credit
    and Collection Policy in regard to each Purchased Receivable that is treated
    as or represented by such Seller to be an Eligible Receivable.

         SECTION 4.02. Representations and Warranties of the Buyer. The Buyer
represents and warrants as follows:

         (a) The Buyer is a limited liability company duly formed, validly
existing and in good standing under the laws of the jurisdiction of its
formation and is duly qualified in good standing as a foreign limited liability
company in each jurisdiction where the failure to be so qualified, individually
or in the aggregate, could not reasonably be expected to have a Buyer Material
Adverse Effect.

         (b) The execution, delivery and performance by the Buyer of this
Agreement (i) have been duly authorized by all necessary limited liability
company action and (ii) will not (A) violate (1) the Buyer's certificate of
formation or limited liability company agreement, (2) any Law applicable to the
Buyer or (3) any provision of any indenture, certificate of designation for
preferred stock, agreement or other instrument to which the Buyer is a party or
by which it or any of its property is or may be bound or (B) be in conflict
with, result in a breach of or constitute (alone or with notice or lapse of time
or both) a default under, give rise to a right of or result in any cancellation
of a material right or acceleration of any material payment obligations under
any such indenture, certificate of designation for preferred stock, agreement or
other instrument, where any such conflict, violation, breach or default referred
to in clause (ii) or this Section 4.02(b), could reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect and (iii) do not
result in or require the creation of any Adverse Claim upon or with respect to
any of its properties. This Agreement has been duly executed and delivered by
the Buyer.

         (c) No authorization or approval or other action by, and no notice to
or filing with, any governmental authority or regulatory body is required for
the due execution, delivery and performance by the Buyer of this Agreement,
except (i) such as have been obtained or made and are in full force and effect
and (ii) for such authorizations, approvals or actions the failure of which to
obtain could not reasonably be expected to result in a Material Adverse Effect.

         (d) This Agreement, when executed and delivered by the Buyer, will be
the legal, valid and binding obligations of the Buyer, enforceable in accordance
with its terms, subject to (i) the effects of bankruptcy, insolvency,
moratorium, reorganization or other similar laws affecting creditors' rights
generally, (ii) general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law) and (iii)
implied covenants of good faith and fair dealing.

                                       19


         (e) There are no actions, suits or proceedings at law or in equity or
by or before any Official Body or in arbitration now pending or, to the actual
knowledge of a Responsible Officer of the Buyer, threatened in writing against
or affecting the Buyer or any of its business, property or rights, which could
reasonably be expected to have a Material Adverse Effect.

                              ARTICLE V. COVENANTS

         SECTION 5.01. Covenants of the Sellers. From the date hereof until the
first day following the Termination Date on which all of the Purchased
Receivables are either collected in full or are written off in accordance with
the Credit and Collection Policy, each Seller covenants and agrees as follows:

         (a) Compliance with Laws, Etc. Such Seller will comply in all respects
    with all applicable Laws and preserve and maintain its corporate existence,
    rights, franchises, qualifications and privileges except to the extent that
    the failure so to comply with such Laws or the failure so to preserve and
    maintain such rights, franchises, qualifications, and privileges could not
    reasonably be expected to have a Material Adverse Effect.

         (b) Offices, Records and Books of Account. Such Seller will keep the
    office where it keeps its records concerning the Purchased Receivables at
    (i) the address of such Seller specified on Schedule I as of the date of
    this Agreement or (ii) upon 30 days' prior written notice to the Buyer, at
    any other locations in jurisdictions where all actions reasonably requested
    by the Buyer to protect and perfect the Buyer's interest in the Purchased
    Receivables have been taken and completed. Such Seller also will maintain
    and implement administrative and operating procedures (including without
    limitation, an ability to recreate records evidencing Purchased Receivables
    and related Contracts in the event of the destruction of the originals
    thereof), and keep and maintain all documents, books, records and other
    information reasonably necessary or advisable for the collection of all
    Purchased Receivables (including, without limitation, records adequate to
    permit the daily identification of each Purchased Receivable and all
    Collections of and adjustments to each existing Purchased Receivable).

         (c) Performance and Compliance with Contracts and Credit and Collection
    Policy. Such Seller will, at its expense, (i) timely and fully perform and
    comply with all material provisions, covenants and other promises required
    to be observed by it under the Contracts related to the Purchased
    Receivables in the same manner as if this Agreement did not exist, and (ii)
    timely and fully comply with the Credit and Collection Policy in regard to
    the Purchased Receivables and the related Contracts.

         (d) Sales, Liens, Etc. Such Seller will not sell, assign (by operation
    of law or otherwise) or otherwise dispose of, or create or suffer to exist
    any Adverse Claim upon or with respect to, any Receivable, Related Security,
    related Contract or Collections, or upon or with respect to any Lock-Box
    Account or the Concentration Account, or assign any right to receive income
    in respect thereof.

                                       20


         (e) Extension or Amendment of Receivables and Contracts. Such Seller
    will not extend, amend or otherwise modify the terms of any Purchased
    Receivable or amend, modify or waive any term or condition of any Contract
    related thereto in a manner that would contravene the Credit and Collection
    Policy.

         (f) Change in Business or Credit and Collection Policy. Such Seller
    will not (i) make any material change in the Credit and Collection Policy
    without the prior written consent of the Buyer or (ii) make any change in
    the character of its business which could reasonably be expected to have a
    Material Adverse Effect. Such Seller will promptly notify the Buyer, the
    Administrative Agent and each Funding Agent in writing of any material
    change in the character of its business or its Credit and Collection Policy.

         (g) Change in Payment Instructions to Obligors. Such Seller will not
    add or terminate any Lock-Box Account from those listed in Exhibit A to this
    Agreement, or make any change in its instructions to Obligors regarding
    payments to be made in respect of the Receivables or payments to be made to
    the Lock-Box Accounts, unless the Buyer shall have received thirty (30)
    days' prior written notice of such addition, termination or change
    (including an updated Exhibit A) and a fully executed Lock-Box Agreement
    with respect to each new Lock-Box Account.

         (h) Deposits to Lock-Box Accounts. Such Seller will instruct, or has
    instructed, all Obligors to remit all their payments in respect of the
    Receivables into a Lock-Box Account (either directly by wire transfer or
    electronic funds transfer or by check mailed to a lock-box maintained by the
    relevant Lock-Box Bank). If such Seller shall receive any Collections
    directly, such Seller shall remit such Collections to a Lock-Box Account no
    less frequently than once per calendar week; provided that if at any time
    the aggregate amount of Collections in the possession of the Sellers, the
    Buyer and the Collection Agent exceeds $500,000, then the Sellers shall
    remit Collections to a Lock-Box Account no later than the next Business Day.
    Such Seller shall use commercially reasonable efforts to prevent funds which
    do not constitute Collections of Receivables from being deposited into any
    Lock-Box Account.

         (i) Audits. Such Seller will, from time to time during regular business
    hours as requested by the Buyer or its assigns upon reasonable prior notice
    and at such Seller's expense, permit the Buyer, or its agents,
    representatives or assigns (including independent public accountants), (i)
    to conduct periodic audits of the Receivables, the Related Security and the
    related books and records and collections systems of such Seller, (ii) to
    examine and make copies of and abstracts from all books, records and
    documents (including, without limitation, computer tapes and disks) in the
    possession or under the control of such Seller relating to Receivables and
    the Receivables Property, including, without limitation, the Contracts, and
    (iii) to visit the offices and properties of such Seller for the purpose of
    examining such materials described in clause (ii) above, and to discuss
    matters relating to Receivables and the Receivables Property or such
    Seller's performance under the Transaction Documents or under the Contracts
    with any of the officers or employees of such Seller having knowledge of
    such matters.

                                       21


         (j) Further Assurances; Change in Name or Jurisdiction of Origination,
    etc. (i) Such Seller agrees from time to time, at its expense, promptly to
    execute and deliver all further instruments and documents, and to take all
    further actions, that may be necessary or desirable, or that the Buyer or
    its assignee may reasonably request, to perfect, protect or more fully
    evidence the Buyer's ownership of the Purchased Receivables, or to enable
    the Buyer or its assignee to exercise and enforce its respective rights and
    remedies under this Agreement. Without limiting the foregoing, such Seller
    will, upon the request of the Buyer or its assignee, (A) execute and file
    such financing or continuation statements, or amendments thereto, and such
    other instruments and documents, that may be necessary or desirable or that
    the Buyer or its assignee may reasonably request to perfect, protect or
    evidence the Buyer's ownership of such Receivables; and (B) following the
    occurrence of a Termination Event, deliver to the Buyer copies of the
    invoices evidencing the Purchased Receivables (which delivery may be made in
    electronic form).

              (ii) Such Seller authorizes the Buyer or its assignee to file
    financing or continuation statements, and amendments thereto and assignments
    thereof, relating to the Receivables and the Related Security, the related
    Contracts and the Collections with respect thereto without the signature of
    such Seller. A photocopy or other reproduction of this Agreement shall be
    sufficient as a financing statement where permitted by law.

              (iii) Such Seller shall not change its jurisdiction of
    organization unless (i) the Buyer shall have received at least ten (10) days
    advance written notice of such change and all action by such Seller
    necessary or appropriate to perfect or maintain the perfection of the
    Buyer's interest in the Receivables and Receivable Property (including,
    without limitation, the filing of all financing statements and the taking of
    such other action as the Buyer may request in connection with such change)
    shall have been duly taken and (ii) the new jurisdiction of organization is
    a State within the United States of America.

              (iv) Such Seller will not change its name, identity or corporate
    structure or tax identification number or the office at which any records
    relating to the Receivables are maintained unless the Buyer shall have
    received at least ten (10) days advance written notice of such change or
    relocation and all action by such Seller necessary or appropriate to perfect
    or maintain the perfection of the Buyer's interest in the Receivables
    (including, without limitation, the filing of all financing statements and
    the taking of such other action as the Buyer may request in connection with
    such change or relocation) shall have been duly taken.

         (k) Reporting Requirements. Such Seller will provide or cause to be
    provided to the Buyer the following:

              (i) promptly upon the occurrence of each Termination Event or
    Incipient Termination Event that relates to such Seller, a statement of a
    financial officer of such Seller setting forth details of such Termination
    Event or Incipient Termination Event and the action that such Seller has
    taken and proposes to take with respect thereto;

                                       22


              (ii) promptly after a Responsible Officer of such Seller obtains
    actual knowledge thereof, notice of the occurrence thereof any event or
    condition that has had, or could reasonably by expected to have, a Material
    Adverse Effect; and

              (iii) such other information respecting the Purchased Receivables
    as the Buyer may from time to time reasonably request.

         (l) Separate Conduct of Business. Such Seller shall not take any action
    that is inconsistent with Section 5.1(o) of the Receivables Transfer
    Agreement.

         (m) Taxes. Such Seller will pay and discharge promptly when due all
    material taxes, assessments and governmental charges or levies imposed upon
    it or upon its income or profits or in respect of its property, before the
    same shall become delinquent or in default, as well as all lawful claims for
    labor, materials and supplies or otherwise that, if unpaid, might give rise
    to a Lien upon such properties or any part thereof; provided, however, that
    such payment and discharge shall not be required with respect to any such
    tax, assessment, charge, levy or claim so long as the validity or amount
    thereof shall be contested in good faith by appropriate proceedings, and
    such Seller shall have set aside on its books reserves in accordance with
    GAAP with respect thereto and such contest effectively suspends collection
    of the contested obligation and the enforcement of any Adverse Claim
    securing such obligation.

         (n) Treatment as Sales. Except to the extent otherwise required under
    GAAP, such Seller shall not account for or treat (whether in financial
    statements or otherwise) the transactions contemplated by this Agreement in
    any manner other than as a sale and absolute conveyance of Receivables by
    such Seller to the Buyer (except that, in accordance with applicable tax
    principles, each Purchase may be ignored for tax reporting purposes).

                    ARTICLE VI. ADMINISTRATION AND COLLECTION

         SECTION 6.01. Designation of Collection Agent. Consistent with the
Buyer's ownership interest in the Purchased Receivables, each Seller
acknowledges and agrees that the servicing, administration and collection of the
Purchased Receivables shall be the responsibility and right of the Buyer and its
assigns. The Buyer has advised the Sellers that (i) the Buyer has sold an
undivided ownership interest in the Purchased Receivables and the Receivables
Property to the Administrative Agent, for the benefit of the Transferees under
the Receivables Transfer Agreement and (ii) the servicing, administration and
collection of the Purchased Receivables and the Receivables Property shall be
conducted by the Person designated as the Collection Agent pursuant to the
Receivables Transfer Agreement from time to time. Pursuant to the Receivables
Transfer Agreement, (i) the Buyer has requested Nalco Company to, and Nalco
Company has agreed that it will, act as the initial Collection Agent and (ii)
Nalco Company has appointed each Seller to act as its Sub-Collection Agent with
respect to the Receivables and the Receivables Property originated by such
Seller and each Seller has accepted such appointment.

                                       23


         SECTION 6.02. Certain Rights of the Buyer. (a) The Buyer may, at any
time, give notice of ownership and/or direct the Obligors of Purchased
Receivables and any Person obligated on any Related Security, or any of them,
that payment of all amounts payable under any Purchased Receivable shall be made
directly to the Buyer or its designee. Each Seller hereby transfers to the Buyer
(and its assigns and designees) the exclusive ownership and control of the
Lock-Box Accounts and each Seller shall take any further action that the Buyer
may reasonably request to effect or further evidence such transfer.


         (b) At any time following the occurrence and during the continuation of
a Termination Event:

              (i) Each Seller shall, upon the Buyer's request and at such
    Seller's expense, give notice of the Buyer's ownership to each Obligor of
    Purchased Receivables and direct that payments of all amounts payable under
    the Purchased Receivables be made directly to the Buyer or its designee.

              (ii) At the Buyer's request and at the expense of the respective
    Sellers, each Seller shall (A) assemble all of the Records, and shall make
    the same available to the Buyer or its designee at a place selected by the
    Buyer or its designee, and (B) segregate all cash, checks and other
    instruments received by it from time to time constituting Collections of
    Receivables in a manner acceptable to the Buyer and, promptly upon receipt,
    remit all such cash, checks and instruments, duly indorsed or with duly
    executed instruments of transfer, to the Buyer or its designee. The Buyer
    shall also have the right to make copies of all such documents, instruments
    and other records at any time.

         (c) Each Seller authorizes the Buyer or its designee and hereby
irrevocably appoints the Buyer or its designee as its attorney-in-fact coupled
with an interest, with full power of substitution and with full authority in
place of such Seller, following the occurrence and during the continuation of a
Termination Event, to take any and all steps in such Seller's name and on behalf
of such Seller, that are necessary or desirable, in the determination of the
Buyer, to collect amounts due under the Purchased Receivables, including,
without limitation, (i) endorsing such Seller's name on checks and other
instruments representing Collections of Purchased Receivables and enforcing the
Purchased Receivables and the Related Security and related Contracts and (ii)
enforcing the Receivables and the Related Security including to ask, demand,
collect, sue for, recover, compromise, receive and give acquittance and receipts
for moneys due and to become due under or in connection with therewith and to
file any claims or take any action or institute any proceedings that the Buyer
(or such designee) may deem to be necessary or desirable for the collection
thereof or to enforce compliance with the terms and conditions of, or to perform
any obligations or enforce any rights of such Seller in respect of, the
Receivables and the Related Security.

         SECTION 6.03. Rights and Remedies. (a) If any Seller fails to perform
any of its obligations under this Agreement, the Buyer may (but shall not be
required to) cause performance of, such obligation, and the costs and expenses
of the Buyer reasonably incurred in connection therewith shall be payable by
such Seller.

                                       24


         (b) Each Seller shall cooperate with the Collection Agent in collecting
amounts due from Obligors in respect of the Purchased Receivables.

                       ARTICLE VII. EVENTS OF TERMINATION

         SECTION 7.01. Events of Termination. If any of the following events
(each a "Termination Event") shall occur and be continuing:

         (a) any Seller shall fail to make any payment or deposit required to be
made by it hereunder or under any of the Transaction Documents when due
hereunder or thereunder and such failure remains unremedied for one Business
Day; or

         (b) any representation, warranty, certification or statement made by
any Seller in this Agreement, any other Transaction Document to which it is a
party or in any other document delivered pursuant hereto or thereto shall prove
to have been incorrect in any material respect when made or deemed made other
than any breach of a representation relating to a Receivable that has been
repurchased pursuant to Section 2.03 or with respect to which the Buyer has
declined to effect such repurchase as provided therein after receipt of notice
of such breach; or

         (c) any Seller shall fail to perform or observe (i) any term, covenant
or agreement contained in Sections 5.01(d), (f), (g), (h), and (l) of this
Agreement or (ii) any other term, covenant or agreement contained in this
Agreement or any other Transaction Document on its part to be performed or
observed and, solely in the case of this clause (ii), such failure shall remain
unremedied for ten (10) days after a Responsible Officer of such Seller has
actual knowledge or receives written notice thereof; or

         (d) any Event of Bankruptcy shall occur with respect to any Seller; or

         (e) (i) any Seller receives notice or becomes aware that a notice of
lien has been filed against such Seller under Section 412(n) of the Code or
Section 302(f) of ERISA for a failure to make a required installment or other
payment to a plan to which Section 412(n) of the Code or Section 302(f) of ERISA
applies or (ii) (A) a Reportable Event or Reportable Events shall have occurred

to such Multiemployer Plan and such person does not have reasonable grounds for
contesting such Withdrawal Liability or is not contesting such Withdrawal
Liability in a timely and appropriate manner, (D) any Seller, any Subsidiary of
any Seller or any ERISA Affiliate shall have been notified by the sponsor of a
Multiemployer Plan that such Multiemployer Plan is in reorganization or is being
terminated, within the meaning of Title IV of ERISA, (E) any Seller, any
Subsidiary of any Seller or any ERISA Affiliate shall engage in any "prohibited
transaction" (as defined in Section 406 of ERISA or Section 4975 of the Code)
involving any Plan or (F) any other similar event or condition shall occur or
exist with respect to a Plan; and in each case in

                                       25


clauses (A) through (F) above, such event or condition, together with all other
such events or conditions, if any, could reasonably be expected to have a
Material Adverse Effect; or

         (f) any "Termination Event" shall occur under the Receivables Transfer
Agreement;

then, and in any such event, the Buyer may, in its discretion, declare the
Termination Date to have occurred with respect to all Sellers or, in the
discretion of the Buyer, any Seller affected by such Termination Event, upon
notice to such Seller or Sellers; provided that, automatically upon the
occurrence of any event (without any requirement for the giving of notice)
described in paragraph (d) of this Section 7.01 with respect to any Seller, the
Termination Date shall occur with respect to such Seller. Upon any such
declaration or upon such automatic termination, the Buyer and its assigns shall
have, in addition to the rights and remedies which it may have under this
Agreement, all other rights and remedies provided after default under the UCC
for a secured party in connection with the sale of accounts and under other
applicable law, which rights and remedies shall be cumulative.

                         ARTICLE VIII. INDEMNIFICATION

         SECTION 8.01. Indemnities by the Sellers. Without limiting any other
rights that the Buyer and its respective officers, directors, employees, agents
and assigns (each, an "Indemnified Party") may have hereunder or under
applicable law, each Seller hereby agrees to indemnify each Indemnified Party
from and against any and all damages, losses, claims, liabilities, deficiencies,
costs, disbursements and expenses, including, without limitation, interest,
penalties, amounts paid in settlement and reasonable attorneys' fees (all of the
foregoing being collectively referred to as "Indemnified Amounts") arising out
of or resulting from any of the following (excluding, however, (a) Indemnified
Amounts to the extent such Indemnified Amounts resulted from gross negligence or
willful misconduct on the part of such Indemnified Party, (b) any income taxes
or any other tax or fee measured by income incurred by such Indemnified Party
arising out of or as a result of this Agreement or the ownership of Purchased
Receivables and (c) Indemnified Amounts arising solely from a delay in payment,
or default by, an Obligor with respect to any Receivable (other than any delay
or default arising out of any discharge, claim, offset or defense of the Obligor
to the payment of any Purchased Receivable arising from the actions or omissions
of such Seller (including, without limitation, a defense based on such Purchased
Receivable not being a legal, valid and binding obligation of such Obligor
enforceable against it in accordance with its terms, but excluding any defense
based on a discharge in bankruptcy)):

              (i) any Receivable which such Seller represents to be or treats as
    an Eligible Receivable but which is not an Eligible Receivable as of the
    date of such representation or treatment;

              (ii) any other representation or warranty certification, report or
    other statement made or deemed made by such Seller (or any of its officers
    or employees) under or in connection with this Agreement or any of the other
    Transaction Documents which shall have been incorrect in any respect when
    made;

                                       26


              (iii) the failure by such Seller to comply with any applicable Law
    with respect to any Receivable or the related Contract; or the failure of
    any Receivable originated by such Seller or the related Contract to conform
    to any such applicable Law;

              (iv) the failure to vest in the Buyer absolute ownership of each
    Purchased Receivable originated by such Seller and the Related Security and
    Collections in respect thereof, free and clear of any Lien;

              (v) the failure to have filed, or any delay in filing, financing
    statements or other similar instruments or documents under the UCC of any
    applicable jurisdiction or other applicable laws with respect to any
    Receivables originated by such Seller and the Related Security and
    Collections in respect thereof, whether at the time of any Purchase or at
    any subsequent time;

              (vi) any dispute, claim, offset or defense (other than discharge
    in bankruptcy) of an Obligor to the payment of any Receivable originated by
    such Seller (including, without limitation, a defense based on such
    Receivable or the related Contract not being a legal, valid and binding
    obligation of such Obligor enforceable against it in accordance with its
    terms), or any other claim resulting from the sale of the merchandise, goods
    or services related to such Receivable or the furnishing or failure to
    furnish such merchandise, goods or services or relating to any Contract
    related thereto;

              (vii) any failure of such Seller to perform its duties or
    obligations in accordance with the provisions hereof and each other
    Transaction Document or to perform its duties or obligations under the
    Contracts or to timely and fully comply in all respects with the Credit and
    Collection Policy in regard to each Receivable originated by such Seller and
    the related Contract;

              (viii) any products liability, environmental or other claim
    arising out of or in connection with merchandise, goods or services which
    are the subject of any Receivable originated by such Seller or Related
    Security;

              (ix) the commingling of Collections of Purchased Receivables at
    any time with other funds;

              (x) any investigation, litigation or proceeding (actual or
    threatened) related to this Agreement or the use of proceeds of Purchases or
    in respect of any Receivable originated by such Seller or Related Security
    or Contract; or

              (xi) the failure by such Seller to pay when due any taxes,
    including, without limitation, sales, excise or personal property taxes.

         Notwithstanding anything to the contrary in this Agreement, solely for
purposes of the Sellers' indemnification obligations pursuant to clauses (ii)
and (vii) of this Article VIII, any representation, warranty or covenant
qualified by the occurrence or non-occurrence of a Material Adverse Effect or
similar concepts of materiality shall be deemed to be not so qualified.

                                       27


                            ARTICLE IX. MISCELLANEOUS

         SECTION 9.01. Amendments, Etc. No amendment or waiver of any provision
of this Agreement or consent to any departure by any Seller or the Collection
Agent therefrom shall be effective unless in a writing signed by the Buyer
(subject to the provisions of Section 9.07) and, in the case of any amendment,
also signed by the Sellers affected thereby, and then such amendment, waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. No failure on the part of the Buyer to exercise, and no
delay in exercising, any right hereunder shall operate as a waiver thereof; nor
shall any single or partial exercise of any right hereunder preclude any other
or further exercise thereof or the exercise of any other right.

         SECTION 9.02. Notices, Etc. Except as provided below, all
communications and notices provided for hereunder shall be in writing (including
telecopy or electronic facsimile transmission or similar writing) and shall be
given to the other party at its address or telecopy number specified on Schedule
I hereto or at such other address or telecopy number as such party may hereafter
specify for the purposes of notice to such party. Each such notice or other
communication shall be effective (i) if given by telecopy, when such telecopy is
transmitted to the telecopy number specified in this Section 9.02 and
confirmation is received, (ii) if given by mail three Business Days following
such posting, postage prepaid, U.S. certified or registered, (iii) if given by
overnight courier, one Business Day after deposit thereof with a national
overnight courier service, or (iv) if given by any other means, when received at
the address specified in this Section 9.02. Each Seller hereby appoints the
Seller Agent as its agent and irrevocably authorizes the Seller Agent to execute
and deliver all notices required hereunder on behalf of the Sellers. Any notice
required to be delivered to any Seller hereunder shall be deemed delivered to
such Seller if delivered to the Seller Agent in accordance with the terms
hereof. The Seller Agent accepts such appointment as agent for the Sellers and
agrees to act thereas until the date on which this Agreement has terminated in
accordance with its terms. Each Seller agrees not to revoke, modify or withdraw
such appointment until terminated pursuant to the preceding sentence..

         SECTION 9.03. Binding Effect; Assignability. (a) This Agreement shall
be binding upon and inure to the benefit of the Sellers, the Collection Agent,
the Buyer and their respective successors and assigns; provided, however, that
neither the Collection Agent nor any Seller may assign its rights or obligations
hereunder or any interest herein without the prior written consent of the Buyer.
The Buyer may assign all or any part of its rights and obligations hereunder (as
security for obligations of the Buyer or otherwise) without the consent of the
Collection Agent or any Seller. In connection with any sale or assignment by the
Buyer of all or a portion of the Purchased Receivables, the purchaser or
assignee, as the case may be, shall, to the extent of its purchase or
assignment, have all rights of the Buyer under this Agreement (as if such
purchaser or assignee, as the case may be, were the Buyer hereunder) subject to
the terms of the agreement between the Buyer and such purchaser or assignee, as
the case may be.

         (b) This Agreement shall create and constitute the continuing
obligations of the parties hereto in accordance with its terms, and shall remain
in full force and effect until such time, after the Termination Date, when all
of the Purchased Receivables are either collected in full or are written off as
uncollectible in accordance with the Credit and Collection Policy;

                                       28


provided, however, that rights and remedies with respect to any breach of any
representation and warranty made by any Seller pursuant to Article IV and the
provisions of Article VIII and Sections 9.04, 9.05 and 9.06 shall be continuing
and shall survive any termination of this Agreement.

         SECTION 9.04. Costs, Expenses and Taxes. (a) In addition to the rights
of indemnification granted to the Buyer pursuant to Article VIII hereof, the
Sellers agree to pay on demand all reasonable costs and expenses in connection
with the preparation, execution, delivery and administration of this Agreement
and the other documents and agreements to be delivered hereunder, including,
without limitation, (i) the reasonable fees and out-of-pocket expenses of
counsel for the Buyer with respect thereto and with respect to advising the
Buyer as to its rights and remedies under this Agreement; (ii) all reasonable
fees and expenses associated with any audits and other due diligence conducted
prior to or after the Closing Date and (iii) any amendments, waivers or consents
under the Transaction Documents. In addition, the Sellers agree to pay all costs
and expenses, if any (including reasonable counsel fees and expenses), in
connection with the enforcement of this Agreement and the other documents to be
delivered hereunder.

         (b) In addition, the Sellers agree to pay any and all stamp and other
taxes and fees payable in connection with the execution, delivery, filing and
recording of this Agreement or the other documents or agreements to be delivered
hereunder, and the Sellers agree to save each Indemnified Party harmless from
and against any liabilities with respect to or resulting from any delay in
paying or omission to pay such taxes and fees.

         SECTION 9.05. No Proceedings. Each Seller, in its capacity as a
creditor of the Buyer, hereby agrees that it will not institute against, or join
any other Person in instituting against, the Buyer any involuntary proceeding of
the type referred to in the definition of "Event of Bankruptcy" in the
Receivables Transfer Agreement so long as there shall not have elapsed one year
plus one day since the date on which all Aggregate Unpaids are paid in full.

         SECTION 9.06. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 9.07. Third Party Beneficiary. Each of the parties hereto
hereby acknowledges that the Buyer may assign all or any portion of its rights
under this Agreement and that such assignees may (except as otherwise agreed to
by such assignees) further assign, or grant security interests in, their rights
under this Agreement, and each Seller and the Collection Agent hereby consents
to any such assignment and grants. All such assignees and secured parties, shall
be third party beneficiaries of, and shall be entitled to enforce the Buyer's
rights and remedies under, this Agreement to the same extent as if they were
parties hereto, subject to the terms of their agreement with the Buyer. Without
limiting the generality of the foregoing, each Seller hereby acknowledges that
the Buyer has assigned all of its rights, remedies and powers hereunder to the
Administrative Agent pursuant to the Receivables Transfer Agreement. Each Seller
agrees that the Administrative Agent (for the benefit of the Transferees under
the Receivables Transfer Agreement) shall, subject to the terms of the
Receivables Transfer Agreement, have the right to enforce this Agreement and to
exercise directly all of the Buyer's

                                       29


rights and remedies under this Agreement (including, without limitation, the
right to give or withhold any consents or approvals of the Buyer to be given or
withheld hereunder) and each Seller agrees to cooperate fully with the
Administrative Agent in the exercise of such rights and remedies. Each Seller
further agrees to give to the Administrative Agent copies of all notices and
reports it is required to give to the Buyer hereunder. Notwithstanding anything
herein to the contrary, (i) no declaration of the Termination Date by the Buyer,
and no other amendment, waiver, consent, request or other modification
(including, without limitation, any request pursuant to Section 2.03) made or
granted by the Buyer hereunder, shall in any case be effective unless the same
shall have been made or granted by, or approved in writing by, the
Administrative Agent (which may make, grant or approve the Termination Date, and
which shall, at the direction of the Required APA Banks make, grant or approve
the Termination Date) and (ii) no declaration of a Non-Payment Event or the
Termination Date by any Seller or the Seller Agent shall in any case be
effective unless notice of such declaration shall have been received by the
Administrative Agent. For the avoidance of doubt, it is understood and agreed
that the Administrative Agent's right to deliver notices to Obligors shall be
subject to Section 6.3 of the Receivables Transfer Agreement.

         SECTION 9.08. Restriction on Payments; Waiver of Setoff. (a)
Notwithstanding anything in this Agreement or elsewhere to the contrary, each
Seller acknowledges and agrees to the restrictions on payments set forth in, and
the other terms of, the Intercompany Note and agrees to be bound thereby to the
same extent as if it were the Holder (as defined in the Intercompany Note)
thereunder.

         (b) Except as otherwise provided herein, the obligations and
liabilities of the Sellers under this Agreement (collectively, the "Seller
Obligations") shall not be subject to deduction of any kind or type, except by
payment in full of the amount thereof in accordance with the terms thereof. Each
Seller hereby waives any right it may now or at any time hereafter have to
set-off any Seller Obligation against any obligation of the Buyer (including,
without limitation, any obligation of the Buyer under the Intercompany Note or
in respect of the payment of the Purchase Price for any Purchased Receivables).

         SECTION 9.09. Execution in Counterparts. This Agreement may be executed
in any number of counterparts, each of which when so executed shall be deemed to
be an original and all of which when taken together shall constitute one and the
same agreement.

         SECTION 9.10. Integration; Survival of Termination. This Agreement and
the other Transaction Documents executed by the parties hereto on the date
hereof contain the final and complete integration of all prior expressions by
the parties hereto with respect to the subject matter hereof and shall
constitute the entire agreement among the parties hereto with respect to the
subject matter hereof superceding all prior oral or written understandings. Any
provisions of this Agreement which are prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         SECTION 9.11. Consent to Jurisdiction. (a) Each party hereto hereby
irrevocably submits to the non-exclusive jurisdiction of any New York State or
Federal court

                                       30


sitting in New York City in any action or proceeding arising out of or relating
to this Agreement, and each party hereto hereby irrevocably agrees that all
claims in respect of such action or proceeding may be heard and determined in
such New York State court or, to the extent permitted by law, in such Federal
court. The parties hereto hereby irrevocably waive, to the fullest extent they
may effectively do so, the defense of an inconvenient forum to the maintenance
of such action or proceeding. The parties hereto agree that a final judgment in
any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

         (b) Each of the Sellers and the Buyer consents to the service of any
and all process in any such action or proceeding by the mailing of copies of
such process to it at its address specified herein. Nothing in this Section 9.11
shall affect the right of any party to serve legal process in any manner
permitted by law.

         SECTION 9.12. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, TRIAL BY JURY IN ANY JUDICIAL
PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN
TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED
WITH THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT.
