<PAGE>   45

                  The Transferor shall, by notice to the Agent given by
telecopy, offer to convey, transfer and assign to the Agent, on behalf of the
Company or the Bank Investors, as applicable, undivided percentage ownership
interests in the Receivables and the other Affected Assets relating thereto at
least three (3) Business Days prior to the proposed date of any Incremental
Transfer. Each such notice shall specify (w) whether such request is made to the
Agent, on behalf of the Company or on behalf of the Bank Investors (it being
understood and agreed that once any Transferred Interest hereunder is acquired
on behalf of the Bank Investors, the Agent, on behalf of Bank Investors, shall
be required to purchase all Transferred Interests, held by the Agent on behalf
of the Company in accordance with Section 9.7 and thereafter no additional
Incremental Transfers shall be acquired on behalf of the Company hereunder), (x)
the desired Transfer Price (which shall be at least $1,000,000 or integral
multiples of $250,000 in excess thereof) or, to the extent that the then
available unused portion of the Facility Limit is less than such amount, such
lesser amount equal to such available portion of the Facility Limit, (y) the
desired date of such Incremental Transfer and (z) the desired Tranche Period(s)
and allocations of the Net Investment of such Incremental Transfer thereto as
required by Section 2.3. The Agent will promptly notify the Company or each of
the Bank Investors, as the case may be, of the Agent's receipt of any request
for an Incremental Transfer to be made to the Agent on behalf of such Person. To
the extent that any such Incremental Transfer is requested of the Agent, on
behalf of the Company, the Company shall instruct the Agent to accept or reject
such offer by notice given to the Transferor and the Agent by telephone or
telecopy by no later than the close of its business on the Business Day
following its receipt of any such request. Each notice of proposed Transfer
shall be irrevocable and binding on the Transferor and the Transferor shall
indemnify the Company and each Bank Investor against any loss or expense
incurred by the Company or any Bank Investor, either directly or indirectly
(including, in the case of the Company, through the Liquidity Provider
Agreement) as a result of any failure for any reason (including failure to
satisfy any of the conditions precedent in respect thereof) by the Transferor to
complete such Incremental Transfer including, without limitation, any loss
(including loss of anticipated profits) or expense incurred by the Company or

<PAGE>   46

any Bank Investor, either directly or indirectly (including, in the case of the
Company, pursuant to the Liquidity Provider Agreement) by reason of the
liquidation or reemployment of funds acquired by the Company (or the Liquidity
Provider) or any Bank Investor (including, without limitation, funds obtained by
issuing commercial paper or promissory notes or obtaining deposits as loans from
third parties) for the Company or any Bank Investor to fund such Incremental
Transfer.

        On the date of the initial Incremental Transfer, the Agent, on behalf of
the Company or the Bank Investors, as applicable, shall deliver written
confirmation to the Transferor of the Transfer Price, the Tranche Period(s) and
the Tranche Rate(s) relating to such Transfer and the Transferor shall deliver
to the Agent the Transfer Certificate in the form of Exhibit F hereto (the
"Transfer Certificate"). The Agent shall indicate the amount of the initial
Incremental Transfer together with the date thereof on the grid attached to the
Transfer Certificate. On the date of each subsequent Incremental Transfer, the
Agent shall send written confirmation to the Transferor of the Transfer Price,
the Tranche Period(s), the Transfer Date and the Tranche Rate(s) applicable to
such Incremental Transfer. The Agent shall indicate the amount of the
Incremental Transfer together with the date thereof as well as any decrease in
the Net Investment on the grid attached to the Transfer Certificate. The
Transfer Certificate shall evidence the Incremental Transfers.

        By no later than 11:00 a.m. (New York time) on any Transfer Date, the
Company or each Bank Investor, as the case may be, shall remit its share (which,
in the case of an Incremental Transfer to the Bank Investors, shall be equal to
such Bank Investor's Pro Rata Share) of the aggregate Transfer Price for such
Transfer to the account of the Agent specified therefor from time to time by the
Agent by notice to such Persons. The obligation of each Bank Investor to remit
its Pro Rata Share of any such Transfer Price shall be several from that of each
other Bank Investor, and the failure of any Bank Investor to so make such amount
available to the Agent shall not relieve any other Bank Investor of its
obligation hereunder. Following each Incremental Transfer and the Agent's
receipt of funds from


<PAGE>   47

the Company or the Bank Investors as aforesaid, the Agent shall remit the
Transfer Price to the Transferor's account at the location indicated in Section
10.3 hereof, in immediately available funds, an amount equal to the Transfer
Price for such Incremental Transfer. Unless the Agent shall have received notice
from the Company or any Bank Investor, as applicable, that such Person will not
make its share of any Transfer Price relating to any Incremental Transfer
available on the applicable Transfer Date therefor, the Agent may (but shall
have no obligation to) make the Company's or any such Bank Investor's share of
any such Transfer Price available to the Transferor in anticipation of the
receipt by the Agent of such amount from the Company or such Bank Investor. To
the extent the Company or any such Bank Investor fails to remit any such amount
to the Agent after any such advance by the Agent on such Transfer Date, the
Company or such Bank Investor, on the one hand, and the Transferor, on the other
hand, shall be required to pay such amount, together with interest thereon at a
per annum rate equal to the Federal funds rate (as determined in accordance with
clause (ii) of the definition of "Base Rate"), in the case of the Company or any
such Bank Investor, or the Base Rate, in the case of the Transferor, to the
Agent upon its demand therefor (provided that the Company shall have no
obligation to pay such interest amounts except to the extent that it shall have
sufficient funds to pay the face amount of its Commercial Paper in full). Until
such amount shall be repaid, such amount shall be deemed to be Net Investment
paid by the Agent and the Agent shall be deemed to be the owner of a Transferred
Interest hereunder. Upon the payment of such amount to the Agent (x) by the
Transferor, the amount of the aggregate Net Investment shall be reduced by such
amount or (y) by the Company or such Bank Investor, such payment shall
constitute such Person's payment of its share of the applicable Transfer Price
for such Transfer.

                (b)     REINVESTMENT TRANSFERS. On each Business Day occurring
after the initial Incremental Transfer hereunder and prior to the Termination
Date, the Transferor hereby agrees to convey, transfer and assign to the Agent,
on behalf of the Company or the Bank Investors, and in consideration of
Transferor's agreement to maintain at all times prior to the Termination Date a
Net Receivables Balance in an amount at least sufficient to maintain the



<PAGE>   48

Percentage Factor at an amount not greater than the Maximum Percentage Factor,
the Agent, on behalf of the Company may, and the Agent, on behalf of the Bank
Investors shall agree to purchase from the Transferor undivided percentage
ownership interests in each and every Receivable, together with Related
Security, Collections and Proceeds with respect thereto, to the extent that
Collections are available for such Transfer in accordance with Section 2.5
hereof, such that after giving effect to such Transfer, (i) the amount of the
Net Investment at the close of business on such Business Day shall be equal to
the amount of the Net Investment at the close of the business on the Business
Day immediately preceding such Business Day plus the Transfer Price of any
Incremental Transfer made on such day, if any, and (ii) the Transferred Interest
in each Receivable, together with Related Security, Collections and Proceeds
with respect thereto, shall be equal to the Transferred Interest in each other
Receivable, together with Related Security, Collections and Proceeds with
respect thereto.

                (c)     ALL TRANSFERS. Each Transfer shall constitute a purchase
by the Agent, on behalf of the Company or the Bank Investors, as applicable, of
undivided percentage ownership interests in each and every Receivable, together
with Related Security, Collections and Proceeds with respect thereto, then
existing, as well as in each and every Receivable, together with Related
Security, Collections and Proceeds with respect thereto, which arises at any
time after the date of such Transfer. The Agent's aggregate undivided percentage
ownership interest in the Receivables, together with the Related Security,
Collections and Proceeds with respect thereto, held on behalf of the Company or
the Bank Investors, as applicable, shall equal the Percentage Factor in effect
from time to time. The Agent shall hold the Transferred Interests on behalf of
the Company and each Bank Investor in accordance with each of the Company's and
each Bank Investor's percentage interest in the Transferred Interest (determined
on the basis of the relationship that the portion of the Net Investment funded
by such Person bears to the aggregate Net Investment of the Company and all of
the Bank Investors at such time).

                (d)     CERTIFICATE. The Transferor shall issue to the Agent the
Certificate, in the form of the Exhibit M, on or prior to the date hereof.

<PAGE>   49
                (e)     PERCENTAGE FACTOR. The Percentage Factor shall be
initially computed by the Collection Agent as of the opening of business of the
Collection Agent on the date of the initial Incremental Transfer hereunder.
Thereafter until the Termination Date, the Collection Agent shall recompute the
Percentage Factor at the time of each Incremental Transfer pursuant to Section
2.2(a) and as of the close of business of the Collection Agent on each Business
Day (other than a day after the Termination Date) and report such recomputation
to the Agent monthly, in the Investor Report, and at such other times as may be
requested by the Agent. The Percentage Factor shall remain constant from the
time as of which any such computation or recomputation is made until the time as
of which the next such recomputation, if any, shall be made, notwithstanding any
additional Receivables arising, any Incremental Transfer made pursuant to
Section 2.2(a) or any Reinvestment Transfer made pursuant to Sections 2.2(b) and
2.5 during any period between computations of the Percentage Factor. The
Percentage Factor, as computed as of the close of business on the Business Day
immediately preceding the Termination Date, shall remain constant at all times
on and after the Termination Date until the date on which the Net Investment has
been reduced to zero, and all accrued Discount and Servicing Fees have been paid
in full and all other Aggregate Unpaids have been paid in full at which time the
Percentage Factor shall be recomputed in accordance with Section 2.6.

        SECTION 2.3. SELECTION OF TRANCHE PERIODS AND TRANCHE RATES.

                (a)     PRIOR TO THE TERMINATION DATE; TRANSFERRED INTEREST HELD
ON BEHALF OF THE COMPANY. At all times hereafter, but prior to the Termination
Date and not with respect to any portion of the Transferred Interest held on
behalf of the Bank Investors (or any of them), the Transferor may, subject to
the Company's approval and the limitations described below, request Tranche
Periods and allocate a portion of the Net Investment to each selected Tranche
Period, so that the aggregate amounts allocated to outstanding Tranche Periods
at all times shall equal the Net Investment held on behalf of the Company. The
Transferor shall give the Company irrevocable notice by telephone of the new
requested Tranche Period(s) at least three (3) Business Days prior to the
expiration of any then existing Tranche Period; PROVIDED, HOWEVER, that the
Company may select, in its sole discretion, any such new Tranche Period if (i)
the Transferor fails to provide such notice on a timely basis or (ii) the
Company determines, in its sole discretion, that the Tranche Period requested by
the Transferor is unavailable or for any reason commercially undesirable. The
Company confirms that it is its intention to allocate all or substantially all
of the Net Investment held on behalf of it to one or more CP Tranche Periods,
provided that the Company may determine, from time to time, in its sole
discretion, that funding such Net Investment by means of one or more CP Tranche
Periods is not possible or is not desirable for any reason. If the Liquidity
Provider acquires from the Company a Purchased Interest with respect to the
Receivables pursuant to the terms of the Liquidity Provider Agreement,
NationsBank, on behalf of the Liquidity Provider, may exercise the right of
selection granted to the Company hereby. The initial Tranche Period applicable
to any such Purchased Interest shall be a period of not greater than 14 days and
such Tranche shall be a BR Tranche. Thereafter, provided that the Termination
Date shall not have occurred, the Tranche Period applicable thereto shall be the
BR Rate or the Eurodollar Rate, as determined by NationsBank. In the case of any
Tranche Period outstanding upon the Termination Date, such Tranche Period shall
end on such date.

<PAGE>   51

                (b)     AFTER THE TERMINATION DATE; TRANSFERRED INTEREST HELD ON
BEHALF OF THE COMPANY. At all times on and after the Termination Date, with
respect to any portion of the Transferred Interest which shall be held by the
Agent on behalf of the Company, the Company or NationsBank, as applicable, shall
select all Tranche Periods and Tranche Rates applicable thereto.

                (c)     PRIOR TO THE TERMINATION DATE; TRANSFERRED INTEREST HELD
ON BEHALF OF BANK INVESTOR. At all times with respect to any portion of the
Transferred Interest held by the Agent on behalf of the Bank Investors, but
prior to the Termination Date, the initial Tranche Period applicable to such
portion of the Net Investment allocable thereto shall be a period of not greater
than 14 days and such Tranche shall be a BR Tranche. Thereafter, with respect to
such portion, and with respect to any other portion of the Transferred Interest
held on behalf of the Bank Investors (or any of them), provided that the
Termination Date shall not have occurred, the Tranche Period applicable thereto
shall be, at the Transferor's option, either a BR Tranche or a Eurodollar
Tranche. The Transferor shall give the Agent irrevocable notice by telephone of
the new requested Tranche Period at least three (3) Business Days prior to the
expiration of any then existing Tranche Period and, if the Transferor shall fail
to provide such notice, the Agent on behalf of the Bank Investors may, in its
sole discretion, select the new Tranche Period in respect of the applicable
Tranche. In the case of any Tranche Period outstanding upon the occurrence of
the Termination Date, such Tranche Period shall end on the date of such
occurrence.

                (d)     AFTER THE TERMINATION DATE; TRANSFERRED INTEREST HELD ON
BEHALF OF BANK INVESTOR. At all times on and after the Termination Date, with
respect to any portion of the Transferred Interest held by the Agent on behalf
of the Bank Investors, the Agent shall select all Tranche Periods and Tranche
Rates applicable thereto.

                (e)     EURODOLLAR RATE PROTECTION; ILLEGALITY. (i) If the Agent
is unable to obtain on a timely basis the information necessary to determine the
LIBOR Rate for any proposed Eurodollar Tranche, then

<PAGE>   52


                (A)     the Agent shall forthwith notify the Company or Bank
        Investors, as applicable and the Transferor that the Eurodollar Rate
        cannot be determined for such Eurodollar Tranche, and

                (B)     while such circumstances exist, neither the Company, the
        Bank Investors or the Agent shall allocate the Net Investment of any
        additional Transferred Interests purchased during such period or
        reallocate the Net Investment allocated to any then existing Tranche
        ending during such period, to a Eurodollar Tranche.

                (ii)    If, with respect to any outstanding Eurodollar Tranche,
the Company or any of the Bank Investors on behalf of which the Agent holds any
Transferred Interest therein notifies the Agent that it is unable to obtain
matching deposits in the London interbank market to fund its purchase or
maintenance of such Transferred Interest or that the Eurodollar Rate applicable
to such Transferred Interest will not adequately reflect the cost to the Person
of funding or maintaining its respective Transferred Interest for such Tranche
Period then the Agent shall forthwith so notify the Transferor, whereupon
neither the Agent nor the Company or the Bank Investors, as applicable, shall,
while such circumstances exist, allocate any Net Investment of any additional
Transferred Interest purchased during such period or reallocate the Net
Investment allocated to any Tranche Period ending during such period, to a
Eurodollar Tranche.

                (iii)   Notwithstanding any other provision of this Agreement,
if the Company or any of the Bank Investors, as applicable, shall notify the
Agent that such Person has determined (or has been notified by any Liquidity
Provider) that the introduction of or any change in or in the interpretation of
any law or regulation makes it unlawful (either for the Company, such Bank
Investor, or such Liquidity Provider, as applicable), or any central bank or
other governmental authority asserts that it is unlawful, for the Company, such
Bank Investor or such Liquidity Provider, as applicable, to fund the purchases
or maintenance of Transferred Interests at the Eurodollar Rate, then (x) as of
the effective date of such notice from such Person to the Agent, the obligation
or ability of the Company or such Bank Investor, as applicable, to fund its

<PAGE>   53

purchase or maintenance of Transferred Interests at the Eurodollar Rate shall be
suspended until such Person notifies the Agent that the circumstances causing
such suspension no longer exist and (y) the Net Investment of each Eurodollar
Tranche in which such Person owns an interest shall either (1) if such Person
may lawfully continue to maintain such Transferred Interest at the Eurodollar
Rate until the last day of the applicable Tranche Period, be reallocated on the
last day of such Tranche Period to another Tranche Period in respect of which
the Net Investment allocated thereto accrues Discount at a Tranche Rate other
than the Eurodollar Rate or (2) if such Person shall determine that it may not
lawfully continue to maintain such Transferred Interest at the Eurodollar Rate
until the end of the applicable Tranche Period, such Person's share of the Net
Investment allocated to such Eurodollar Tranche shall be deemed to accrue
Discount at the Base Rate from the effective date of such notice until the end
of such Tranche Period.

<PAGE>   54

        SECTION 2.4. DISCOUNT, FEES AND OTHER COSTS AND EXPENSES.
Notwithstanding the limitation on recourse under Section 2.1 hereof, the
Transferor shall pay, as and when due in accordance with this Agreement, all
fees hereunder, Discount (including Discount due the Company or any Bank
Investor), all amounts payable pursuant to Article VIII hereof, if any, and the
Servicing Fees. On the last day of each Tranche Period, the Transferor shall pay
to the Agent, on behalf of the Company or the Bank Investors, as applicable, an
amount equal to the accrued and unpaid Discount for such Tranche Period together
with, in the event the Transferred Interest is held on behalf of the Company, an
amount equal to the discount accrued on the Company's Commercial Paper to the
extent such Commercial Paper was issued in order to fund the Transferred
Interest in an amount in excess of the Transfer Price of an Incremental
Transfer. The Transferor shall pay to the Agent, on behalf of the Company, on
each day on which Related Commercial Paper is issued by the Company, the Dealer
Fee. Discount shall accrue with respect to each Tranche on each day occurring
during the Tranche Period related thereto. Nothing in this Agreement shall limit
in any way the obligations of the Transferor to pay the amounts set forth in
this Section 2.4.


<PAGE>   55

        SECTION 2.5. NON-LIQUIDATION SETTLEMENT AND REINVESTMENT PROCEDURES. On
each day after the date of any Incremental Transfer but prior to the Termination
Date and provided that no Potential Termination Event shall have occurred and be
continuing, the Collection Agent shall, out of the Percentage Factor of
Collections received on or prior to such day and not previously applied or
accounted for: (i) set aside and hold in trust for the Agent, on behalf of the
Company or the Bank Investors, as applicable (or deposit into the Collection
Account if so required pursuant to Section 2.12 hereof), an amount equal to all
Discount and the Servicing Fee accrued through such day and not so previously
set aside or paid and (ii) apply the balance of such Percentage Factor of
Collections remaining after application of Collections as provided in clause (i)
of this Section 2.5 hereof to the Transferor, for the benefit of the Agent, on
behalf of the Company or the Bank Investors, as applicable, to the purchase of
additional undivided percentage interests in each Receivable pursuant to Section
2.2(b) hereof. On the last day of each Tranche Period, from the amounts set
aside as described in clause (i) of the first sentence of this Section 2.5
hereof, the Collection Agent shall deposit to the Agent's account, for the
benefit of the Company or the Bank Investors, as applicable, an amount equal to
the accrued and unpaid Discount for such Tranche Period and shall deposit to its
own account an amount equal to the accrued and unpaid Servicing Fee for such
Tranche Period. The Agent, upon its receipt of such amounts in the Agent's
account, shall distribute such amounts to the Company and/or the Bank Investors
entitled thereto as set forth above; provided that if the Agent shall have
insufficient funds to pay all of the above amounts in full on any such date, the
Agent shall pay such amounts ratably (based on the amounts owing to each such
Person) to all such Persons entitled to payment thereof. In addition, the
Collection Agent shall remit to the Transferor at the end of each Tranche
Period, such portion of Collections not allocated to the Agent, on behalf of
Company or the Bank Investors, as applicable.

        SECTION 2.6. LIQUIDATION SETTLEMENT PROCEDURES. If at any time on or
prior to the Termination Date, the Percentage Factor is greater than the Maximum
Percentage Factor, then the Transferor shall immediately pay to the Agent, for
the benefit of the Company or the Bank Investors, 


<PAGE>   56

as applicable, from previously received Collections, an amount equal to the
amount such that, when applied in reduction of the Net Investment, will result
in a Percentage Factor less than or equal to the Maximum Percentage Factor. Such
amount shall be applied to the reduction of the Net Investment of Tranche
Periods selected by the Agent. On the Termination Date and on each day
thereafter, and on each day on which a Termination Event or a Potential
Termination Event has occurred and is continuing, the Collection Agent shall set
aside and hold in trust for the Agent, on behalf of the Company or the Bank
Investors, as applicable (or deposit into the Collection Account if so required
pursuant to Section 2.12 hereof) the Percentage Factor of all Collections
received on such day and shall set aside and hold in trust for the Transferor
such portion of Collections not allocated to the Agent, on behalf of the Company
or the Bank Investors, as applicable. On the Termination Date or the day on
which a Termination Event or Potential Termination Event has occurred and is
continuing, the Collection Agent shall deposit to the Agent's account, for the
benefit of the Company or the Bank Investors, as applicable, any amounts set
aside pursuant to Section 2.5 above. On the last day of each Tranche Period to
occur on or after the Termination Date, during the continuance of a Termination
Event or Potential Termination Event, the Collection Agent shall deposit to the
Agent's account to the extent not already so deposited, for the benefit of the
Company or the Bank Investors, as applicable, the amounts so set aside for the
Agent, on behalf of the Company or the Bank Investors, pursuant to the second
preceding sentence, but not to exceed the sum of (i) the accrued Discount for
such Tranche Period, (ii) the portion of the Net Investment allocated to such
Tranche Period, and (iii) all other Aggregate Unpaids. On such day, the
Collection Agent shall deposit to its account, from the amounts set aside for
the Company and the Bank Investors pursuant to the preceding sentence which
remain after payment in full of the aforementioned amounts, the accrued
Servicing Fee for such Tranche Period. If there shall be insufficient funds on
deposit for the Collection Agent to distribute funds in payment in full of the
aforementioned amounts, the Collection Agent shall distribute funds FIRST, in
payment of the accrued Discount, SECOND, if the Transferor, the Seller or any
Affiliate of the Transferor or the Seller is not then the Collection Agent, to
the Collection Agent's account, in 


<PAGE>   57

payment of the Servicing Fee payable to the Collection Agent, THIRD, in
reduction of the Net Investment allocated to any Tranche Period ending on such
date, FOURTH, in payment of all fees payable by the Transferor hereunder, FIFTH,
in payment of all other Aggregate Unpaids and SIXTH, if the Transferor, the
Seller or any Affiliate of the Transferor or the Seller is the Collection Agent,
to its account as Collection Agent, in payment of the Servicing Fee payable to
such Person as Collection Agent. The Agent, upon its receipt of such amounts in
the Agent's account, shall distribute such amounts to the Company and/or the
Bank Investors entitled thereto as set forth above; provided that if the Agent
shall have insufficient funds to pay all of the above amounts in full on any
such date, the Agent shall pay such amounts in the order of priority set forth
above and, with respect to any such category above for which the Agent shall
have insufficient funds to pay all amounts owing on such date, ratably (based on
the amounts in such categories owing to such Persons) among all such Persons
entitled to payment thereof.

        Following the later to occur of the Termination Date and the date on
which the Net Investment has been reduced to zero, all accrued Discount and
Servicing Fees have been paid in full and all other Aggregate Unpaids have been
paid in full, (i) the Collection Agent shall recompute the Percentage Factor,
(ii) the Agent, on behalf of the Company and the Bank Investors, shall be
considered to have reconveyed to the Transferor all of the right, title and
interest in and to the Affected Assets (including the Transferred Interest)
without recourse, representation or warranty of any type or kind, (iii) the
Collection Agent shall pay to the Transferor any remaining Collections set aside
and held by the Collection Agent pursuant to the third sentence of this Section
2.6 and (iv) the Agent, on behalf of the Company and the Bank Investors, shall
execute and deliver to the Transferor, at the Transferor's expense, such
documents or instruments as are necessary to terminate the Agent's interests in
the Affected Assets. Any such documents shall be prepared by or on behalf of the
Transferor. On the last day of each Tranche Period, the Collection Agent shall
remit to the Transferor such portion of Collections set aside for the Transferor
pursuant to this Section 2.6.

<PAGE>   58
        SECTION 2.7. FEES. Notwithstanding any limitation on recourse contained
in this Agreement, the Transferor shall pay the following non-refundable fees:

                (a)     On the last day of each month, to the Company solely for
its own account, the Program Fee and the Administrative Fee, and the Facility
Fee to the Agent for distribution to the Bank Investors.

                (b)     On the date of execution hereof, to the Administrative
Agent solely for its own account, the Arrangement Fee.

        SECTION 2.8. PROTECTION OF OWNERSHIP INTEREST OF THE COMPANY AND THE
BANK INVESTORS; SPECIAL ACCOUNTS AND CONCENTRATION ACCOUNT. (a) The Transferor
agrees that it will, and will cause the Seller to, from time to time, at its
expense, promptly execute and deliver all instruments and documents and take all
actions as may be necessary or as the Agent may reasonably request in order to
perfect or protect the Transferred Interest or to enable the Agent, the Company
or the Bank Investors to exercise or enforce any of their respective rights
hereunder. Without limiting the foregoing, the Transferor will, and will cause
the Seller to, upon the request of the Agent, the Company or any of the Bank
Investors, in order to accurately reflect this purchase and sale transaction,
execute and file such financing or continuation statements or amendments thereto
or assignments thereof as permitted pursuant to Section 9.7 hereof as may be
requested by the Agent, the Company or any of the Bank Investors and (y) mark
its respective master data processing records and other documents with a legend
describing the conveyance to the Transferor of the Receivables (in the case of
the Seller) and to the Agent, for the benefit of the Company and the Bank
Investors, of the Transferred Interest. The Transferor shall, and will cause the
Seller to, upon request of the Agent, the Company or any of the Bank Investors
obtain such additional search reports as the Agent, the Company or any of the
Bank Investors shall request. To the fullest extent permitted by applicable law,
the Agent shall be permitted to sign and file continuation statements and
amendments thereto and assignments thereof without the Transferor's or the
Seller's signature. Carbon, photographic or other reproduction of this Agreement
or any financing statement shall be sufficient as a financing 


<PAGE>   59
statement. The Transferor shall not, and shall not permit the Seller to, change
its respective name, identity or corporate structure (within the meaning of
Section 9-402(7) of the UCC as in effect in any applicable state) nor relocate
its respective chief executive office or any office where Records are kept
unless it shall have: (i) given the Agent at least thirty (30) days prior notice
thereof and (ii) prepared at Transferor's expense and delivered to the Agent all
financing statements, instruments and other documents necessary to preserve and
protect the Transferred Interest or requested by the Agent in connection with
such change or relocation. Any filings under the UCC or otherwise that are
occasioned by such change in name or location shall be made at the expense of
Transferor.

                (b)     The Agent is hereby authorized at any time to date, and
to deliver to the Concentration Account Bank, the Concentration Account Notice
delivered hereunder. The Transferor hereby, when the Agent shall deliver the
Concentration Account Notice to the Concentration Account Bank, transfers to the
Agent the exclusive ownership and control of the Concentration Account, and
shall take any further action that the Agent may reasonably request to effect
such transfer. In case any authorized signatory of the Transferor whose
signature shall appear on the Concentration Account Agreement shall cease to
have such authority before the delivery of the Concentration Account Notice,
such signature shall nevertheless be valid and sufficient for all purposes as if
such authority had remained in force at the time of such delivery. The Agent
shall, at the time it delivers the Concentration Account Notice to the
Concentration Account Bank, provide a copy thereof to the Transferor; PROVIDED
that the failure on the part of the Agent to provide such notice to the
Transferor shall not affect the validity or effectiveness of the Concentration
Account Notice or impair any rights of the Agent, the Company or any of the Bank
Investors hereunder.

                (c)     In addition and without limiting the authority of the
Agent set forth in subsection (b) above, but subject to subsection (d) below,
the Transferor shall cause each Originating Entity to instruct any or all of the
Special Account Banks (which instructions shall be maintained in full force and
effect at all times) to transfer directly to the Concentration Account all


<PAGE>   60

Collections from time to time on deposit in the applicable Special Accounts on a
daily basis in accordance with the terms set forth in the applicable Special
Account Letter. In the event the Transferor shall at any time determine, for any
of the reasons described in subsection (d) below, that the Transferor or any
Originating Entity shall be unable to comply fully with the requirements of this
subsection (c), the Transferor shall promptly so advise the Agent, and the
Transferor and the Agent shall commence discussions with a view toward
implementing an alternative arrangement therefor satisfactory to the Agent.

                (d)     Anything to the contrary herein notwithstanding, all
Medicare or Medicaid payments which are made by an Obligor with respect to any
Receivables shall be collected from such Obligor only by (i) the applicable
Originating Entity or (ii) an agent of such Originating Entity, EXCEPT to the
extent that an Obligor may be required to submit any such payments directly to a
Person other than such Originating Entity pursuant to a court-ordered assignment
which is valid, binding and enforceable under applicable federal and state
Medicare Regulations and Medicaid Regulations; and neither this Agreement nor
any other Transaction Document shall be construed to permit any other Person, in
violation of applicable Medicare Regulations or Medicaid Regulations to collect
or receive, or to be entitled to collect or receive, any such payments prior to
such Originating Entity's or such agent's receipt thereof.

        SECTION 2.9. DEEMED COLLECTIONS; APPLICATION OF PAYMENTS. (a) If on any
day the Outstanding Balance of a Receivable is either (x) reduced as a result of
any defective, rejected or returned merchandise or services, any discount,
credit, Contractual Adjustment, rebate, dispute, warranty claim, repossessed or
returned goods, chargeback, allowance, any billing adjustment or other
adjustment, or (y) reduced or canceled as a result of a setoff or offset in
respect of any claim by any Person (whether such claim arises out of the same or
a related transaction or an unrelated transaction), the Transferor shall be
deemed to have received on such day a Collection of such Receivable in the
amount of such reduction or cancellation and the Transferor shall pay to the
Collection Agent an amount equal to such reduction or cancellation and such
amount shall be 


<PAGE>   61

applied by the Collection Agent as a Collection in accordance with Section 2.5
or 2.6 hereof, as applicable. The Net Investment shall be reduced by the amount
of such payment applied to the reduction of the Net Investment and actually
received by the Agent.

                (b)     If on any day any of the representations or warranties
in Article III was or becomes untrue with respect to a Receivable (whether on or
after the date of any transfer of an interest therein to the Agent, the Company
or the Bank Investors as contemplated hereunder), the Transferor shall be deemed
to have received on such day a Collection on such Receivable in full and the
Transferor shall on such day pay to the Collection Agent an amount equal to the
Outstanding Balance of such Receivable and such amount shall be allocated and
applied by the Collection Agent as a Collection allocable to the Transferred
Interest in accordance with Section 2.5 or 2.6 hereof, as applicable. The Net
Investment shall be reduced by the amount of such payment applied to the
reduction of the Net Investment and actually received by the Agent.

                (c)     Any payment by an Obligor in respect of any indebtedness
owed by it to the Transferor or the Seller shall, except as otherwise specified
by such Obligor or otherwise required by contract or law and unless otherwise
instructed by the Agent, be applied as a Collection of any Receivable of such
Obligor included in the Transferred Interest (starting with the oldest such
Receivable) or the extent of any amounts then due and payable thereunder before
being applied to any other receivable or other indebtedness of such Obligor.

        SECTION 2.10. PAYMENTS AND COMPUTATIONS, ETC. All amounts to be paid or
deposited by the Transferor or the Collection Agent hereunder shall be paid or
deposited in accordance with the terms hereof no later than 11:00 a.m. (New York

are payable to the Agent (whether on behalf of the Company or any Bank Investor
or otherwise) they shall be paid or deposited in the account indicated in
Section 10.3 hereof, until otherwise notified by the Agent. The Transferor
shall, to the extent permitted by law, pay to the Agent, for the benefit of the
Company and the Bank Investors upon demand, interest on all amounts not 


<PAGE>   62

paid or deposited when due hereunder at a rate equal to 2% per annum plus the
Base Rate. All computations of Discount, interest and all per annum fees
hereunder shall be made on the basis of a year of 360 days for the actual number
of days (including the first but excluding the last day) elapsed. Any
computations by the Agent of amounts payable by the Transferor hereunder shall
be binding upon all parties hereto absent manifest error.

        SECTION 2.11. REPORTS. On or prior to the last Business Day of each
month, the Collection Agent shall prepare and forward to the Agent and the
Administrative Agent (i) an Investor Report as of the end of the last day of the
immediately preceding month, (ii) a listing by Primary Payor of all Receivables
together with an analysis as to the aging of such Receivables as of such last
day, (iii) written confirmation that all payments in cash, by way of credits to
intercompany accounts (in the case of purchases made by the Seller from any
Transferring Affiliate) or by way of application of proceeds of advances made
under the Subordinated Note (in the case of purchases made by the Transferor
from the Seller) have been made by the Transferor under the Receivables Purchase
Agreement or by the Seller under the Transferring Affiliate Letter or the BMA
Transfer Agreement, as applicable, in accordance with the respective terms of
such agreement, and (iv) such other information as the Agent or the
Administrative Agent may reasonably request.

        SECTION 2.12. COLLECTION ACCOUNT. There shall be established on the day
of the initial Incremental Transfer hereunder and maintained with the Agent, a
segregated account (the "COLLECTION ACCOUNT"), bearing a designation clearly
indicating that the funds deposited therein are held for the benefit of the
Agent, on behalf of the Company and the Bank Investors. During the continuance
of a Collection Agent Default or a Termination Event or a Potential Termination
Event, the Collection Agent shall remit daily within forty-eight hours of
receipt to the Collection Account all Collections received with respect to any
Receivables. Funds on deposit in the Collection Account (other than investment
earnings) shall be invested by the Agent in Eligible Investments that will
mature so that such funds will be available prior to the last day of each
successive Tranche Period following such investment. On the



<PAGE>   63

last day of each Tranche Period, such funds on deposit, together with all
interest and earnings (net of losses and investment expenses) thereon, in the
Collection Account shall be made available for application in accordance with
the terms of Section 2.6 or otherwise for application toward payments required
to be made hereunder (including Discount) by the Transferor. On the date on
which the Net Investment is zero, all accrued Discount and Servicing Fees have
been paid in full and all other Aggregate Unpaids have been paid in full, any
funds remaining on deposit in the Collection Account shall be paid to the
Transferor.

        SECTION 2.13. SHARING OF PAYMENTS, ETC. If the Company or any Bank
Investor (for purposes of this Section only, being a "NPRBI") shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
setoff, or otherwise) on account of Transferred Interest owned by it (other than
pursuant to Section 2.7, or Article VIII and other than as a result of the
differences in the timing of the applications of Collections pursuant to Section
2.5 or 2.6) in excess of its ratable share of payments on account of Transferred
Interest obtained by the Company and/or the Bank Investors entitled thereto,
such NPRBI shall forthwith purchase from the Company and/or the Bank Investors
entitled to a share of such amount participations in the Transferred Interests
owned by such Persons the excess payment ratably with each such other Person
entitled thereto; PROVIDED, HOWEVER, that if all or any portion of such excess
payment is thereafter recovered from such NPRBI, such purchase from each such
other Person shall rescinded and each such other Person shall repay to the NPRBI
the purchase price paid by such NPRBI for such participation to the extent of
such recovery, together with an amount equal to such other Person's ratable
share (according to the proportion of (a) the amount of such other Person's
required payment to (b) the total amount so recovered from the NPRBI) of any
interest or other amount paid or payable by the NPRBI in respect of the total
amount so recovered.

        SECTION 2.14. RIGHT OF SETOFF. Without in any way limiting the
provisions of Section 2.13, each of the Company and the Bank Investors is hereby
authorized (in addition to any other rights it may have) at any time after the
occurrence of the Termination Date or during the 


<PAGE>   64

continuance of a Potential Termination Event to setoff, appropriate and apply
(without presentment, demand, protest or other notice which are hereby expressly
waived) any deposits (other than any deposits then being held in any Special
Account maintained by a Bank Investor as to which deposits the Bank Investors
waive their rights of set-off in request of the Aggregate Unpaid) and any other
indebtedness held or owing by the Company or such Bank Investor to, or for the
account of, the Transferor against the amount of the Aggregate Unpaids owing by
the Transferor to such Person or to the Agent on behalf of such Person (even if
contingent or unmatured).

direct or indirect wholly-owned subsidiaries of NMC (other than the Transferring
Affiliates) now owned or hereafter acquired, is primarily engaged in the same
business as is conducted on the date hereof by the Originating Entities or 
(ii) NMC reorganizes its corporate structure such that facilities generating
Receivables on the date hereof (or acquired as contemplated by clause (i)) are

the wholly-owned subsidiaries referred to in clauses (i) and (ii) may,
following 30-days' prior written notice by the Transferor to the Agent and with

duly executed by such subsidiary or subsidiaries and (y) the documents relating
to such subsidiary or subsidiaries of the kind delivered by or on behalf of the
Transferring Affiliates (other than BMA) pursuant to Section 4.1, together with

request in connection therewith.

                (b)     Upon the addition of any wholly-owned subsidiary of NMC
as a Transferring Affiliate pursuant to subsection (a) above, the provisions of
this Agreement, including Exhibit Q, shall, without further act or
documentation, be deemed amended to apply to such subsidiary to the same extent
as the same apply to the Transferring Affiliates as of the date hereof and the
term "Transferring Affiliate" in this Agreement shall mean and refer to such


<PAGE>   65

subsidiary as well as each then existing Transferring Affiliate.

(other than the Agent under the Concentration Account Agreement) dominion and
control over the Concentration Account, or the right to take dominion and
control over the Concentration Account at a future time or upon the occurrence

Effect.

                          ADMINISTRATION AND COLLECTION

        SECTION 6.1. APPOINTMENT OF COLLECTION AGENT. The servicing,
administering and collection of the Receivables shall be conducted by such
Person (the "COLLECTION AGENT") so designated from time to time in accordance
with this Section 6.1. Until the Company gives notice to the Transferor of the
designation of a new Collection Agent, NMC is hereby designated as, and hereby
agrees to perform the duties and obligations of, the Collection Agent pursuant
to the terms hereof. The Collection Agent may not delegate any of its rights,
duties or obligations hereunder, or designate a substitute Collection Agent,
without the prior written consent of the Agent; PROVIDED that the Collection
Agent may from time to time delegate to any Originating Entity such of its
rights, duties and obligations hereunder as relate to the servicing,
administering and collection of the Receivables originated by such Originating
Entity; PROVIDED FURTHER that (i) any such delegation shall be terminated upon
the replacement of the Collection Agent hereunder and (ii) the Collection Agent
shall continue to remain solely liable for the performance of the duties as
Collection Agent hereunder notwithstanding any such delegation hereunder. The
Agent may, and upon the direction of the Majority Investors the Agent shall,
after the occurrence of a Collection Agent Default or any other Termination
Event designate as Collection Agent any Person (including itself) to succeed NMC
or any successor Collection Agent, on the conditions in each case that any such
Person so designated shall agree to perform the duties and obligations of the
Collection Agent pursuant to the terms hereof and such designation of such
Person is permitted by applicable law (including, without limitation, applicable
CHAMPUS/VA Regulations, Medicaid Regulations and Medicare Regulations) or any
order of a court of competent jurisdiction. The Agent may notify any Obligor as
to the ownership interest therein that shall have been transferred to the
Transferor and, except as otherwise provided hereunder, as to the Transferred
Interest hereunder.

        SECTION 6.2. DUTIES OF COLLECTION AGENT.

<PAGE>   100
                (a)     The Collection Agent shall take or cause to be taken all
such action as may be necessary or advisable to collect each Receivable from
time to time, all in accordance with applicable laws, rules and regulations
(including, without limitation, all CHAMPUS/VA Regulations, Medicaid Regulations
and Medicare Regulations), with reasonable care and diligence, and in accordance
with the Credit and Collection Policy. Each of the Transferor, the Company, the
Agent and the Bank Investors hereby appoints as its agent the Collection Agent,
from time to time designated pursuant to Section 6.1 hereof, to enforce its
respective rights and interests in and under the Affected Assets. To the extent
permitted by applicable law, the Transferor hereby grants to any Collection
Agent appointed hereunder an irrevocable power of attorney to take any and all
steps in the Transferor's and/or any Originating Entity's name and on behalf of
the Transferor necessary or desirable, in the reasonable determination of the
Collection Agent, to collect all amounts due under any and all Receivables,
including, without limitation, endorsing the Transferor's and/or any Originating
Entity's name on checks and other instruments representing Collections and
enforcing such Receivables and the related Contracts. The Transferor represents
and warrants that the foregoing power of attorney, in the case of any
Originating Entity, has been duly granted to the Transferor under the
Receivables Purchase Agreement and the Transferor is authorized under the
Receivables Purchase Agreement, to the extent permitted by applicable law, to
authorize the Collection Agent hereunder to exercise such power. The Collection
Agent shall set aside for the account of the Transferor and the Agent their
respective allocable shares of the Collections of Receivables in accordance with
Sections 2.5 and 2.6 hereof. The Collection Agent shall segregate and deposit to
the Agent's account the Agent's allocable share of Collections of Receivables
when required pursuant to Article II hereof. So long as no Termination Event
shall have occurred and be continuing, the Collection Agent may, in accordance
with the Credit and Collection Policy, extend the maturity or adjust the
Outstanding Balance of any Defaulted Receivable as the Collection Agent may
determine to be appropriate to maximize Collections thereof; PROVIDED, HOWEVER,
that such extension or adjustment shall not alter the status of such Receivable
as a Defaulted Receivable. The Transferor shall deliver to the Collection Agent
and the Collection Agent shall hold in


<PAGE>   101

trust for the Transferor, and the Agent, on behalf of the Company and the Bank
Investors, in accordance with their respective interests, all Records which
evidence or relate to Receivables or Related Security. Notwithstanding anything
to the contrary contained herein, the Agent shall have the absolute and
unlimited right to direct the Collection Agent (whether the Collection Agent is
NMC or any other Person) to commence or settle any legal action to enforce
collection of any Receivable or to foreclose upon or repossess any Related
Security. The Collection Agent shall not make the Agent, the Company or any of
the Bank Investors a party to any litigation without the prior written consent
of such Person.

                (b)     The Collection Agent shall, as soon as practicable
following receipt thereof, turn over to the Transferor any collections of any
indebtedness of any Person which is not on account of a Receivable. If the
Collection Agent is not NMC or an Affiliate thereof, the Collection Agent, by
giving three Business Days' prior written notice to the Agent, may revise the
percentage used to calculate the Servicing Fee so long as the revised percentage
will not result in a Servicing Fee that exceeds 110% of the reasonable and
appropriate out-of pocket costs and expenses of such Collection Agent incurred
in connection with the performance of its obligations hereunder as documented to
the reasonable satisfaction of the Agent, PROVIDED, HOWEVER, that at any time
after the Percentage Factor equals or exceeds 98%, any compensation to the
Collection Agent in excess of the Servicing Fee initially provided for herein
shall be an obligation of the Transferor and shall not be payable, in whole or
in part, from the Collections allocated to the Company or the Bank Investors, as
applicable. The Collection Agent, if other than NMC, shall as soon as
practicable upon demand, deliver to the Transferor all Records in its possession
which evidence or relate to indebtedness of an Obligor which is not a
Receivable.

                (c)     On or before 90 days after the end of each fiscal year
of the Collection Agent, beginning with the fiscal year ending December 31,
1997, the Collection Agent shall cause a firm of independent public accountants
(who may also render other services to the Collection Agent, the Transferor, the
Seller or any Affiliates of any of the foregoing), the Business Credit Field
Exam Group of 


<PAGE>   102

NationsBank, N.A. or such other Person as may be approved by the Agent, to
furnish a report to the Agent to the effect that they have (any of the foregoing
being an "Auditor"): (i) compared the information contained in the Investor
Reports delivered during such fiscal year then ended with the information
contained in the Contracts and the Collection Agent's records and computer
systems for such period, and that, on the basis of such examination and
comparison, such Auditor is of the opinion that the information contained in the
Investor Reports reconciles with the information contained in the Contracts and
the Collection Agent's records and computer system and that the servicing of the
Receivables has been conducted in compliance with this Agreement, (ii) confirmed
the Net Receivables Balance as of the end of each Tranche Period during such
fiscal year, and (iii) verified that the Receivables treated by the Collection
Agent as Eligible Receivables in fact satisfied the requirements of the
definition thereof contained herein except, in each case, for (a) such
exceptions as such Auditor shall believe to be immaterial (which exceptions need
not be enumerated) and (b) such other exceptions as shall be set forth in such
statement.

                (d)     Notwithstanding anything to the contrary contained in
this Article VI, the Collection Agent, if not the Transferor or NMC, shall have
no obligation to collect, enforce or take any other action described in this
Article VI with respect to any indebtedness that is not included in the
Transferred Interest other than to deliver to the Transferor the collections and
documents with respect to any such indebtedness as described in Section 6.2 (b)
hereof.

        SECTION 6.3. RIGHT AFTER DESIGNATION OF NEW COLLECTION AGENT. At any
time following the designation of a Collection Agent (other than the Transferor,
the Seller or any Affiliate of the Transferor or the Seller) pursuant to Section
6.1 hereof:


                        (i)     The Agent may direct that payment of all amounts
        payable under any Receivable be made directly to the Agent or its
        designee.

                        (ii)    The Transferor shall, at the Agent's request and
        at the Transferor's expense, give 

<PAGE>   103

        notice of the Agent's, the Transferor's and/or the Bank Investors'
        ownership of Receivables to each Obligor and direct that payments be
        made directly to the Agent or its designee.

                        (iii)   The Transferor shall, at the Agent's request,
        (A) assemble all of the Records, and shall make the same available to
        the Agent or its designee at a place selected by the Agent 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 Agent and shall, promptly upon receipt,
        remit all such cash, checks and instruments, duly endorsed or with duly
        executed instruments of transfer, to the Agent or its designee.

                        (iv)    The Transferor hereby authorizes the Agent to
        take, to the extent permitted by applicable law, any and all steps in
        the Transferor's or any Originating Entity's name (which power, in the
        case of each Originating Entity, the Transferor is authorized to grant
        pursuant to authority granted to the Transferor under the Receivables
        Purchase Agreement) and on behalf of the Transferor and such Originating
        Entity necessary or desirable, in the determination of the Agent, to
        collect all amounts due under any and all Receivables, including,
        without limitation, endorsing the Transferor's or such Originating
        Entity's name on checks and other instruments representing Collections
        and enforcing such Receivables and the related Contracts.

Notwithstanding the foregoing clauses (i), (ii), (iii) and (iv), the Agent shall
not at any time direct, or cause the Transferor or any Originating Entity to
direct, Obligors of Receivables or Related Security payable under the Medicare
or Medicaid program to make payment of amounts due or to become due to the
Transferor or any Originating Entity in respect of such Receivables or Related
Security directly to the Concentration Account or to the Agent or its designee,
EXCEPT for any such payment in respect of such Receivables or Related Security
or any assignment thereof that is established by, or made pursuant to, the order
of a court of competent jurisdiction.

        SECTION 6.4. COLLECTION AGENT DEFAULT. The occurrence of any one or more
of the following events shall constitute a Collection Agent Default:

                (a)     (i) the Collection Agent or, to the extent that the
Transferor, the Seller or any Affiliate of the Transferor or the Seller is then
acting as Collection Agent, the Transferor, the Seller or such Affiliate, as

Documents to which such Person is a party or by which such Person is bound, and
such failure shall remain unremedied for ten (10) days, or (iii) the Collection
Agent or, the extent that the Transferor, the Seller or any Affiliate of the

shall fail to observe or perform any term, covenant or agreement on the
Collection Agent's part to be performed under Section 2.8(b) hereof; or

                (b)     any representation, warranty, certification or statement
made by the Collection Agent or the Transferor, the Seller or any Affiliate of
the Transferor or the Seller (in the event that the Transferor, the Seller or
such Affiliate is then acting as the Collection Agent) in this Agreement, the
Receivables Purchase Agreement, the Transferring Affiliate Letter, the BMA
Transfer Agreement or in any of the other Transaction Documents or in any
certificate or report delivered by it pursuant to any of the foregoing shall

regardless of whether such event is an "event of default" or "default" under any
such agreement; or any Indebtedness of the Collection Agent or any of its
Subsidiaries, FMC or FMCH greater than $5,000,000 shall be declared to be due
and payable or required to be prepaid (other than by a regularly scheduled

                (d)     any Event of Bankruptcy shall occur with respect to the
Collection Agent or any of its Subsidiaries; PROVIDED that in the case of any
immaterial Subsidiary of the Collection Agent, if an Event of Bankruptcy shall

Agent Default unless such proceeding shall have remained undismissed or unstayed
for a period of 60 days; or

other event shall have occurred which, in the commercially reasonably judgment
of the Agent, materially and adversely affects the Collection Agent's ability to
either collect the Receivables or to perform under this Agreement.

        SECTION 6.5. RESPONSIBILITIES OF THE TRANSFEROR. Anything herein to the
contrary notwithstanding, the Transferor shall, and/or shall cause each

Letter, the BMA Transfer Agreement and the Receivables Purchase Agreement shall
not relieve the Transferor or the Seller from such obligations and (ii) pay when
due any taxes, including without limitation, any sales taxes payable in

        other charge (other than Excluded Taxes) with respect to this Agreement,
        the other Transaction Documents, the ownership, maintenance or 


<PAGE>   117

        financing of the Transferred Interest, the Receivables or payments of

        by the Credit Support Provider or otherwise in respect of this
        Agreement, the other Transaction Documents, the ownership, maintenance
        or financing of the Transferred Interest or the Receivables (except for
        changes in the rate of general corporate, franchise, net income or other
        income tax imposed on such Indemnified Party by the jurisdiction in
        which such Indemnified Party's principal executive office is located);

                (ii)    shall impose, modify or deem applicable any reserve,
        special deposit or similar requirement (including, without limitation,
        any such requirement imposed by the Board of Governors of the Federal
        Reserve System) against assets of, deposits with or for the account of,
        or credit extended by, any Indemnified Party or shall impose on any
        Indemnified Party or on the United States market for certificates of
        deposit or the London interbank market any other condition affecting
        this Agreement, the other Transaction Documents, the ownership,
        maintenance or financing of the Transferred Interest, the Receivables or
        payments of amounts due hereunder or its obligation to advance funds
        hereunder under the Liquidity Provider Agreement or the credit support
        provided by the Credit Support Provider or otherwise in respect of this
        Agreement, the other Transaction Documents, the ownership, maintenance
        or financing of the Transferred Interest or the Receivables; or

                (iii)   imposes upon any Indemnified Party any other expense
        (including, without limitation, reasonable attorneys' fees and expenses,

<PAGE>   118

        or financing of the Transferred Interest, the Receivables or payments of
        amounts due hereunder or its obligation to advance funds hereunder under
        the Liquidity Provider Agreement or the credit support furnished by the
        Credit Support Provider or otherwise in respect to this Agreement, the
        other Transaction Documents, the ownership, maintenance or financing of
        the Transferred Interests or the Receivables, and the result of any of
        the foregoing is to increase the cost to such Indemnified Party with
        respect to this Agreement, the other Transaction Documents, the
        ownership, maintenance or financing of the Transferred Interest, the
        Receivables, the obligations hereunder, the funding of any purchases
        hereunder, the Liquidity Provider Agreement or the Credit Support
        Agreement, by an amount deemed by such Indemnified Party to be material,

then, within ten (10) days after demand by such Indemnified Party through the
Agent, the Transferor shall pay to the Agent, for the benefit of such
Indemnified Party, such additional amount or amounts as will compensate such
Indemnified Party for such tax, increased cost or reduction.

                (b)     If any Indemnified Party shall have determined that
after the date hereof, the adoption of any applicable Law or bank regulatory
guideline regarding capital adequacy, or any change therein, or any change in
the interpretation thereof by any Official Body, or any directive regarding
capital adequacy (in the case of any bank regulatory guideline, whether or not
having the force of law) of any such Official Body, has or would have the effect
of reducing the rate of return on capital of such Indemnified Party (or its
parent) as a consequence of such Indemnified Party's obligations hereunder or
with respect hereto to a level below that which such Indemnified Party (or its
parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Indemnified Party to be material, then from time to time,
within ten (10) days after demand by such Indemnified Party through the Agent,
the Transferor shall pay to the Agent, for the benefit of such Indemnified
Party, such additional amount or amounts as will compensate such Indemnified
Party (or its parent) for such reduction.



<PAGE>   119

                (c)     The Agent will promptly notify the Transferor of any
event of which it has knowledge, occurring after the date hereof, which will
entitle an Indemnified Party to compensation pursuant to this Section 8.2. A
notice by the Agent or the applicable Indemnified Party claiming compensation
under this Section and setting forth the additional amount or amounts to be paid
to it hereunder shall be conclusive in the absence of manifest error. In
determining such amount, the Agent or any applicable Indemnified Party may use
any reasonable averaging and attributing methods.

                (d)     Anything in this Section 8.2 to the contrary
notwithstanding, if the Company enters into agreements for the acquisition of
interests in receivables from one or more Other Transferors, the Company shall
allocate the liability for any amounts under this Section 8.2 which are in
connection with the Liquidity Provider Agreement, the Credit Support Agreement
or the credit support provided by the Credit Support Provider ("SECTION 8.2
COSTS") to the Transferor and each Other Transferor; PROVIDED, HOWEVER, that if
such Section 8.2 Costs are attributable to any Parent Group Member and not
attributable to any Other Transferor, the Transferor shall be solely liable for
such Section 8.2 Costs or if such Section 8.2 Costs are attributable to Other
Transferors and not attributable to any Parent Group Member, such Other
Transferors shall be solely liable for such Section 8.2 Costs.

        SECTION 8.3. TAXES. (a) All payments made hereunder by the Transferor or
the Collection Agent (each, a "Payor") to the Company, any Bank Investor or the
Agent (each, a "Recipient") shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and
any other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority on any recipient (or any assignee of
such parties) (such non-excluded items being called "Taxes"), but excluding
franchise taxes and taxes imposed on or measured by the recipient's net income
or gross receipts ("Excluded Taxes"). In the event that any withholding or
deduction from any payment made by the Payor

<PAGE>   120


hereunder is required in respect of any Taxes, then such Payor shall:

                (i)     pay directly to the relevant authority the full amount
required to be so withheld or deducted;

                (ii)    promptly forward to the Agent an official receipt or
other documentation satisfactory to the Agent evidencing such payment to such
authority; and

                (iii)   pay to the Recipient such additional amount or amounts
as is necessary to ensure that the net amount actually received by the Recipient
will equal the full amount such Recipient would have received had no such
withholding or deduction been required.

Moreover, if any Taxes are directly asserted against any Recipient with respect
to any payment received by such Recipient hereunder, the Recipient may pay such
Taxes and the Payor will promptly pay such additional amounts (including any
penalties, interest or expenses) as shall be necessary in order that the net
amount received by the Recipient after the payment of such Taxes (including any
Taxes on such additional amount) shall equal the amount such Recipient would
have received had such Taxes not been asserted. Notwithstanding the foregoing,
the Payor shall not be obligated to pay any such additional amounts pursuant to
clause (iii) above or pursuant to the immediately preceding sentence to a Bank
Investor that is not organized under the laws of the United States of America or
a state thereof if such Bank Investor shall have failed to comply with the
requirements of paragraph (b) of this Section 8.3 as of the time such Taxes are
due and payable.

        If the Payor fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Recipient the required receipts or other
required documentary evidence, the Payor shall indemnify the Recipient for any
incremental Taxes, interest, or penalties that may become payable by any
Recipient as a result of any such failure.

                (b)     Each Bank Investor that is not incorporated under the
laws of the United States of America or a state thereof shall:



<PAGE>   121

                (X)     (i) on or before the date of any payment by a Payor to
        such Bank Investor, deliver to such Payor and the Agent (A) two (2) duly
        completed copies of United States Internal Revenue Service Form 1001 or
        4224, or successor applicable form, as the case may be, certifying that
        it is entitled to receive payments hereunder without deduction or
        withholding of any United States federal income taxes and (B) an
        Internal Revenue Service Form W-8 or W-9, or successor applicable form,
        as the case may be, certifying that it is entitled to an exemption from
        United States backup withholding tax;

                (ii)    deliver to each Payor and the Agent two (2) further
        copies of any such form or certification on or before the date that any
        such form or certification expires or becomes obsolete and after the
        occurrence of any event requiring a change in the most recent form
        previously delivered by it to such Payor; and

                (iii)   obtain such extensions of time for filing and complete
        such forms or certifications as may reasonably be requested by either
        Payor or the Agent; or

                (Y)     Each Bank Investor or transferee that is not a "bank"
        under Section 881(c)(3)(A) of the Internal Revenue Code thereof shall:

                (i)     on or before the date it becomes a party hereto (or, in
        the case of a participant, on or before the date such participant
        becomes a participant hereunder), deliver to each Payor and the Agent
        (i) a statement under penalties of perjury that such Bank Investor or
        transferee (x) is not a "bank" under Section 881(c)(3)(A) of the
        Internal Revenue Code, is not subject to regulatory or other legal
        requirements as a bank in any jurisdiction, and has not been treated as
        a bank for purposes of any tax, securities law or other filing or
        submission made to any governmental authority, any application made to a
        rating agency or qualification for any exemption from tax, securities
        law or other legal requirements, (y) is not a 10-percent shareholder
        within the meaning of Section 
<PAGE>   122

        811(c)(3)(B) of the Internal Revenue Code and (z) is not a controlled
        foreign corporation receiving interest from a related person within the
        meaning of Section 881(c)(3)(C) of the Internal Revenue Code and (ii) a
        properly completed and duly executed Internal Revenue Service Form W-8
        or applicable successor form;

                (ii)    deliver to each Payor and the Agent two further properly
        completed and duly executed copies of such Form W-8 expires or becomes
        obsolete or after the occurrence of any event requiring a change in the
        most recent form previously delivered by it to such Payor or upon the
        request of such Payor; and

                (iii)   obtain such extensions of time for filing and completing
        such forms or certifications as may be reasonably requested by either
        Payor or the Agent;

unless in any such case any change in treaty, law or regulation has occurred
after the date such Person becomes a Bank Investor hereunder which renders all
such forms inapplicable or which would prevent such Bank Investor from duly
completing and delivering any such form with respect to it and such Bank
Investor so advises each payor and the Agent. Each Person that shall become a
Bank Investor or a participant of a Bank Investor pursuant to subsection 10.6
shall, upon the effectiveness of the related transfer, be required to provide
all of the forms, certifications and statements required pursuant to this
subsection, PROVIDED that in the case of a participant of a Bank Investor the
obligations of such participant of a Bank Investor pursuant to this subsection
(b) shall be determined as if the participant of a Bank Investor were a Bank
Investor except that such participant of a Bank Investor shall furnish all such
required forms, certifications and statements to the Bank Investor from which
the related participation shall have been purchased.

        SECTION 8.4. OTHER COSTS, EXPENSES AND RELATED MATTERS. (a) The
Transferor agrees, upon receipt of a written invoice, to pay or cause to be
paid, and to save the Company, the Bank Investors and the Agent harmless against
liability for the payment of, all reasonable out-of-pocket expenses (including,
without limitation, attorneys', accountants' and other third parties' fees and

Bank Investors and/or the Agent) or intangible, documentary or recording taxes

connection with the negotiation, execution, delivery and preparation of this
Agreement, the other Transaction Documents and any documents or instruments

or thereby (including, without limitation, the perfection or protection of the
Transferred Interest) and (ii) from time to time (a) relating to any amendments,
waivers or consents under this Agreement and the other Transaction Documents,

disagreement, litigation or preparation for litigation involving this Agreement
or any of the other Transaction Documents (all of such amounts, collectively,

the Company and the Bank Investors, as applicable, on demand any Early
Collection Fee due on account of the reduction of a Tranche on a day prior to
the last day of its Tranche Period.

        SECTION 8.5. RECONVEYANCE UNDER CERTAIN CIRCUMSTANCES. The Transferor
agrees to accept the reconveyance from the Agent, on behalf of the Company
and/or the Bank Investors, of the Transferred Interest if the Agent notifies

Transaction Documents as are delegated to the Agent by the terms hereof and
thereof, together with such powers as are reasonably incidental thereto. In
furtherance, and without limiting the generality, of the foregoing, the Company
and each Bank Investor hereby appoints the Agent as its agent to execute and
deliver all further instruments and documents, and take all further action that
the Agent may deem necessary or appropriate or that the Company or a Bank
Investor may reasonably request in order to perfect, protect or more fully
evidence the interests transferred or to be transferred from time to time by the
Transferor hereunder, or to enable any of them to exercise or enforce any of
their respective rights hereunder, including, without limitation, the execution
by the Agent as secured party/assignee of such financing or continuation
statements, or amendments thereto or assignments thereof, relative to all or any
of the Receivables now existing or hereafter arising, and such other instruments
or notices, as may be necessary or appropriate for the purposes stated
hereinabove. The Company and the Majority Investors may direct the Agent to take
any such incidental action hereunder. With respect to other actions which are
incidental to the actions specifically delegated to the Agent hereunder, the
Agent shall not be required to take any such incidental action hereunder, but
shall be required to act or to refrain from acting (and shall be fully protected
in acting or refraining from acting) upon the direction of the Majority
Investors; PROVIDED, HOWEVER, the Agent shall not be required to take any action
hereunder if the taking of such action, in the reasonable determination of the
Agent, shall be in violation of any applicable law, rule or regulation or
contrary to any provision of this Agreement or shall expose the Agent to
liability hereunder or otherwise. Upon the occurrence and during the continuance
of any Termination Event or Potential Termination Event, the Agent shall take no
action hereunder (other than ministerial actions or such actions as are
specifically provided for herein) without the prior consent of the Majority
Investors (which consent shall not be unreasonably withheld or delayed). The
Agent shall not, without the prior written consent of all Bank Investors, 


<PAGE>   127

agree to (i) amend, modify or waive any provision of this Agreement in any way
which would (A) reduce or impair Collections or the payment of Discount or fees
payable hereunder to the Bank Investors or delay the scheduled dates for payment
of such amounts, (B) increase the Servicing Fee (other than as permitted
pursuant to Section 6.2(b)), (C) modify any provisions of this Agreement or the
Receivables Purchase Agreement or the Parent Agreement relating to the timing of
payments required to be made by the Transferor, any Originating Entity, FMC or
FMCH or the application of the proceeds of such payments, (D) permit the
appointment of any Person (other than the Agent) as successor Collection Agent,
(E) release any property from the lien provided by this Agreement (other than as
expressly contemplated herein) or (F) extend or permit the extension of the
Commitment Termination Date without the consent of each Bank Investor. The Agent
shall not agree to any amendment of this Agreement which increases the dollar
amount of a Bank Investor's Commitment without the prior consent of such Bank
Investor. In addition, the Agent shall not agree to any amendment of this
Agreement not specifically described in the two preceding sentences without the
consent of the related Majority Investors (which consent shall not be
unreasonably withheld or delayed). In the event the Agent requests the Company's
or a Bank Investor's consent pursuant to the foregoing provisions and the Agent
does not receive a consent (either positive or negative) from the Company of
such Bank Investor within 10 Business Days of the Company's or Bank Investor's
receipt of such request, then the Company or such Bank Investor (and its
percentage interest hereunder) shall be disregarded in determining whether the
Agent shall have obtained sufficient consent hereunder.

                (b)     The Agent shall exercise such rights and powers vested
in it by this Agreement and the other Transaction Documents, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of such person's own affairs.

        SECTION 9.2. AGENT'S RELIANCE, ETC. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it or them as Agent under or in connection with this
Agreement or any of the other Transaction Documents, 


<PAGE>   128


except for its or their own gross negligence or willful misconduct. Without
limiting the foregoing, the Agent: (i) may consult with legal counsel (including
counsel for any Parent Group Member), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (ii) makes no warranty or representation to the Company
or any Bank Investor and shall not be responsible to the Company or any Bank
Investor for any statements, warranties or representations made in or in
connection with this Agreement; (iii) shall not have any duty to ascertain or to
inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement or any of the other Transaction Documents on the
part of any Parent Group Member or the Collection Agent or to inspect the
property (including the books and records) of any Parent Group Member or the
Collection Agent; (iv) shall not be responsible to the Company or any Bank
Investor for the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement, any of the other Transaction Documents
or any other instrument or document furnished pursuant hereto or thereto; and
(v) shall incur no liability under or in respect of this Agreement or any of the
other Transaction Documents by acting upon any notice (including notice by
telephone), consent, certificate or other instrument or writing (which may be by
telex) believed by it to be genuine and signed or sent by the proper party or
parties. SECTION 9.3. CREDIT DECISION. The Company and each Bank Investor
acknowledges that it has, independently and without reliance upon the Agent, any
of the Agent's Affiliates, any other Bank Investor or the Company (in the case
of any Bank Investor) and based upon such documents and information as it has
deemed appropriate, made its own evaluation and decision to enter into this
Agreement and the other Transaction Documents to which it is a party and, if it
so determines, to accept the transfer to the Agent on its behalf of any
undivided ownership interest in the Affected Assets hereunder. The Company and
each Bank Investor also acknowledges that it will, independently and without
reliance upon the Agent, any of the Agent's Affiliates, any other Bank Investor
or the Company (in the case of any Bank Investor) and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own 


<PAGE>   129

decisions in taking or not taking action under this Agreement and the other
Transaction Documents to which it is a party.

        SECTION 9.4. INDEMNIFICATION OF THE AGENT. The Bank Investors agree to
indemnify the Agent (to the extent not reimbursed by the Transferor), ratably in
accordance with their Pro Rata Shares, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent in any way relating to or arising
out of this Agreement or any action taken or omitted by the Agent, any of the
other Transaction Documents hereunder or thereunder, provided that the Bank
Investors shall not be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent's gross negligence or willful misconduct.
Without limitation of the foregoing, the Bank Investors agree to reimburse the
Agent, ratably in accordance with their Pro Rata Shares, promptly upon demand
for any out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement and the
other Transaction Documents, to the extent that such expenses are incurred in
the interests of or otherwise in respect of the Bank Investors hereunder and/or
thereunder and to the extent that the Agent is not reimbursed for such expenses
by the Transferor.

        SECTION 9.5. SUCCESSOR AGENT. The Agent may resign at any time by giving
written notice thereof to each Bank Investor, the Company and the Transferor and
may be removed at any time with cause by the Majority Investors. Upon any such
resignation or removal, the Company and the Majority Investors shall appoint a
successor Agent. The Company and each Bank Investor agrees that it shall not
unreasonably withhold or delay its approval of the appointment of a successor
Agent. If no such successor Agent shall have been so appointed, and shall have
accepted such appointment, within 30 days after the retiring Agent's giving of
notice of resignation or the Majority Investors' 


<PAGE>   130


removal of the retiring Agent, then the retiring Agent may, on behalf of the
Company and the Bank Investors, appoint a successor Agent which successor Agent
shall be either (i) a commercial bank organized under the laws of the United
States or of any state thereof and have a combined capital and surplus of at
least $50,000,000 or (ii) an Affiliate of such a bank. Upon the acceptance of
any appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement. After any
retiring Agent's resignation or removal hereunder as Agent, the provisions of
this Article IX shall continue to inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Agreement.

        SECTION 9.6. PAYMENTS BY THE AGENT. Unless specifically allocated to a
Bank Investor pursuant to the terms of this Agreement, all amounts received by
the Agent on behalf of the Bank Investors shall be paid by the Agent to the Bank
Investors (at their respective accounts specified in their respective Assignment
and Assumption Agreements) in accordance with their respective related pro rata
interests in the Net Investment on the Business Day received by the Agent,
unless such amounts are received after 12:00 noon on such Business Day, in which
case the Agent shall use its reasonable efforts to pay such amounts to the Bank
Investors on such Business Day, but, in any event, shall pay such amounts to the
Bank Investors in accordance with their respective related pro rata interests in
the Net Investment not later than the following Business Day.

        SECTION 9.7. BANK COMMITMENT; ASSIGNMENT TO BANK INVESTORS.

                (a)     BANK COMMITMENT. At any time on or prior to the
Commitment Termination Date, in the event that the Company does not effect an
Incremental Transfer as requested under Section 2.2(a), then at any time, the
Transferor shall have the right to require the Company to assign its interest in
the Net Investment in whole to the Bank Investors pursuant to this Section 9.7.
In addition, at any time on or prior to the Commitment Termination Date, 


<PAGE>   131


(i) upon the occurrence of a Termination Event that results in the Termination
Date or (ii) the Company elects to give notice to the Transferor of a
Reinvestment Termination Date, the Transferor hereby requests and directs that
the Company assign its interest in the Net Investment in whole to the Bank
Investors pursuant to this Section 9.7 and the Transferor hereby agrees to pay
the amounts described in Section 9.7(d) below. Provided that the Net Asset Test
is satisfied, upon any such election by the Company or any such request by the
Transferor, the Company shall make such assignment and the Bank Investors shall
accept such assignment and shall assume all of the Company's obligations
hereunder. In connection with any assignment from the Company to the Bank
Investors pursuant to this Section 9.7, each Bank Investor shall, on the date of
such assignment, pay to the Company an amount equal to its Assignment Amount.
Upon any assignment by the Company to the Bank Investors contemplated hereunder,
the Company shall cease to make any additional Incremental Transfers hereunder.

                (b)     ASSIGNMENT. No Bank Investor may assign all or a portion
of its interests in the Net Investment, the Receivables, and Collections,
Related Security and Proceeds with respect thereto and its rights and
obligations hereunder to any Person unless approved in writing by the
Administrative Agent, on behalf of the Company, and the Agent. In the case of an
assignment by the Company to the Bank Investors or by a Bank Investor to another
Person, the assignor shall deliver to the assignee(s) an Assignment and
Assumption Agreement in substantially the form of Exhibit G attached hereto,
duly executed, assigning to the assignee a pro rata interest in the Net
Investment, the Receivables, and Collections, Related Security and Proceeds with
respect thereto and the assignor's rights and obligations hereunder and the
assignor shall promptly execute and deliver all further instruments and
documents, and take all further action, that the assignee may reasonably
request, in order to protect, or more fully evidence the assignee's right, title
and interest in and to such interest and to enable the Agent, on behalf of such
assignee, to exercise or enforce any rights hereunder and under the other
Transaction Documents to which such assignor is or, immediately prior to such
assignment, was a party. Upon any such assignment, (i) the assignee shall have
all of the rights and obligations of the assignor hereunder and under the other
Transaction



<PAGE>   132

Documents to which such assignor is or, immediately prior to such assignment,
was a party with respect to such interest for all purposes, it being understood
that the Bank Investors, as assignees, shall (x) be obligated to fund
Incremental Transfers under Section 2.2(a) in accordance with the terms thereof,
notwithstanding that the Company was not so obligated and (y) not have the right
to elect the commencement of the amortization of the Net Investment pursuant to
the definition of "Reinvestment Termination Date", notwithstanding that the
Company had such right) and (ii) the assignor shall relinquish its rights with
respect to such interest for all purposes of this Agreement and under the other
Transaction Documents to which such assignor is or, immediately prior to such
assignment, was a party. No such assignment shall be effective unless a fully
executed copy of the related Assignment and Assumption Agreement shall be
delivered to the Agent and the Transferor. All costs and expenses of the Agent
and the assignor and assignee incurred in connection with any assignment
hereunder shall be borne by the Transferor and not by the assignor or any such
assignee. No Bank Investor shall assign any portion of its Commitment hereunder
without also simultaneously assigning an equal portion of its interest in the
Liquidity Provider Agreement.

                (c)     EFFECTS OF ASSIGNMENT. By executing and delivering an
Assignment and Assumption Agreement, the assignor and assignee thereunder
confirm to and agree with each other and the other parties hereto as follows:
(i) other than as provided in such Assignment and Assumption Agreement, the
assignor makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in
connection with this Agreement, the other Transaction Documents or any other
instrument or document furnished pursuant hereto or thereto or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
Agreement, the other Transaction Documents or any such other instrument or
document; (ii) the assignor makes no representation or warranty and assumes no
responsibility with respect to the financial condition of the Transferor, any
Parent Group Member or the Collection Agent or the performance or observance by
the Transferor, any Parent Group Member or the Collection Agent of any of their
respective obligations under this Agreement, the Receivables Purchase Agreement,
the Transferring Affiliate Letter, the BMA Transfer Agreement, the Parent
Agreement, the other Transaction Documents or any other instrument or document
furnished pursuant hereto; (iii) such assignee confirms that it has received a
copy of this Agreement, the Receivables 



<PAGE>   133

Purchase Agreement, the Transferring Affiliate Letter, the BMA Transfer
Agreement, the Parent Agreement, and such other instruments, documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such Assignment and Assumption Agreement and to purchase
such interest; (iv) such assignee will, independently and without reliance upon
the Agent, or any of its Affiliates, or the assignor and based on such
agreements, 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 Agreement and the other Transaction Documents; (v) such assignee appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement, the other Transaction Documents and
any other instrument or document furnished pursuant hereto or thereto as are
delegated to the Agent by the terms hereof or thereof, together with such powers
as are reasonably incidental thereto and to enforce its respective rights and
interests in and under this Agreement, the other Transaction Documents, the
Receivables, the Contracts and the Related Security; (vi) such assignee agrees
that it will perform in accordance with their terms all of the obligations which
by the terms of this Agreement and the other Transaction Documents are required
to be performed by it as the assignee of the assignor; and (vii) such assignee
agrees that it will not institute against the Company any proceeding of the type
referred to in Section 10.9 prior to the date which is one year and one day
after the payment in full of all Commercial Paper issued by the Company.

                (d)     TRANSFEROR'S OBLIGATION TO PAY CERTAIN AMOUNTS;
ADDITIONAL ASSIGNMENT AMOUNT. The Transferor shall pay to the Agent, for the
account of the Company, in connection with any assignment by the Company to the
Bank Investors pursuant to this Section 9.7, an aggregate amount equal to all
Discount to accrue through the end of each outstanding Tranche Period plus all
other Aggregate Unpaids (other than the Net Investment). To the extent that such
Discount relates to interest or discount on Related 


<PAGE>   134

Commercial Paper, if the Transferor fails to make payment of such amounts at or
prior to the time of assignment by the Company to the Bank Investors, such
amount shall be paid by the Bank Investors (in accordance with their respective
Pro Rata Shares) to the Company as additional consideration for the interests
assigned to the Bank Investors and the amount of the "Net Investment" hereunder
held by the Bank Investors shall be increased by an amount equal to the
additional amount so paid by the Bank Investors.

                (e)     ADMINISTRATION OF AGREEMENT AFTER ASSIGNMENT. After any
assignment by the Company to the Bank Investors pursuant to this Section 9.7
(and the payment of all amounts owing to the Company in connection therewith),
all rights of the Administrative Agent and the Collateral Agent set forth herein
shall be deemed to be afforded to the Agent on behalf of the Bank Investors
instead of either such party.

                (f)     PAYMENTS. After any assignment by the Company to the
Bank Investors pursuant to this Section 9.7, all payments to be made hereunder
by the Transferor or the Collection Agent to the Company shall be made to the
Agent's account as such account shall have been notified to the Transferor and
the Collection Agent.

                (g)     DOWNGRADE OF BANK INVESTOR. If (at any time prior to any
assignment by the Company to the Bank Investors as contemplated pursuant to this
Section 9.7) the short term debt rating of any Bank Investor shall be "A-2" or
"P-2" from Standard & Poor's or Moody's, respectively, with negative credit
implications, such Bank Investor, upon request of the Agent, shall, within 30
days of such request, assign its rights and obligations hereunder to another
financial institution (which institution's short term debt shall be rated at
least "A-2" and "P-2" from Standard & Poor's and Moody's, respectively, and
which shall not be so rated with negative credit implications). If the short
term debt rating of a Bank Investor shall be "A-3" or "P-3", or lower, from
Standard & Poor's or Moody's, respectively (or such rating shall have been
withdrawn by Standard & Poor's or Moody's), such Bank Investor, upon request of
the Agent, shall, within five (5) Business Days of such request, assign its
rights and obligations hereunder to another financial institution (which
institution's short term debt shall be



<PAGE>   135


rated at least "A-2" and "P-2" from Standard & Poor's and Moody's, respectively,
and which shall not be so rated with negative credit implications). In either
such case, if any such Bank Investor shall not have assigned its rights and
obligations under this Agreement within the applicable time period described
above, the Company shall have the right to require such Bank Investor to accept
the assignment of such Bank Investor's Pro Rata Share of the Net Investment;
such assignment shall occur in accordance with the applicable provisions of this
Section 9.7. Such Bank Investor shall be obligated to pay to the Company, in
connection with such assignment, in addition to the Pro Rata Share of the Net
Investment, an amount equal to the Interest Component of the outstanding
Commercial Paper issued to fund the portion of the Net Investment being assigned
to such Bank Investor, as reasonably determined by the Agent. Notwithstanding
anything contained herein to the contrary, upon any such assignment to a
downgraded Bank Investor as contemplated pursuant to the immediately preceding
sentence, the aggregate available amount of the Facility Limit, solely as it
relates to new Incremental Transfers by the Company, shall be reduced by the
amount of unused Commitment of such downgraded Bank Investor; it being
understood and agreed, that nothing in this sentence or the two preceding
sentences shall affect or diminish in any way any such downgraded Bank
Investor's Commitment to the Transferor or such downgraded Bank Investor's other
obligations and liabilities hereunder and under the other Transaction Documents.

                                  MISCELLANEOUS


        SECTION 10.1. TERM OF AGREEMENT. This Agreement shall terminate on the
date following the Termination Date upon which the Net Investment has been
reduced to zero, all accrued Discount and Servicing Fees have been paid in full
and all other Aggregate Unpaids have been paid in full, in each case, in cash;
PROVIDED, HOWEVER, that (i) the rights and remedies of the Agent, the Company,
the Bank Investors and the Administrative Agent with respect to any
representation and warranty made or deemed to be made by the Transferor pursuant
to this Agreement, (ii) the indemnification and payment provisions of Article
VIII, and (iii) the agreement set forth in Section 10.9 hereof, shall be
continuing and shall survive any termination of this Agreement.

        SECTION 10.2. WAIVERS; AMENDMENTS. No failure or delay on the part of
the Agent, the Company, the Administrative Agent or any Bank Investor in
exercising any power, right or remedy under this Agreement shall operate as a
waiver thereof, nor shall any single or partial exercise of any such power,
right or remedy preclude any other further exercise thereof or the exercise of
any other power, right or remedy. The rights and remedies herein provided shall
be cumulative and nonexclusive of any rights or remedies provided by law. Any
provision of this Agreement may be amended or waived if, but only if, in the
case of any amendment, such amendment is in writing and is signed by the
Transferor, the Company, the Agent and the Majority Investors and in the case of
any waiver, such waiver is granted in writing by the Agent.

        SECTION 10.3. NOTICES. 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 set forth below 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

given by overnight courier, one (1) 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 10.3. However, anything in
this Section to the contrary notwithstanding, the Transferor hereby authorizes
the Company and the Agent to effect Transfers, Tranche Period and Tranche Rate
selections based on telephonic notices made by any Person which the Company or
the Agent in good faith believes to be acting on behalf of the Transferor. The
Transferor agrees to deliver promptly to the Company and the Agent a written
confirmation of each telephonic notice signed by an authorized officer of
Transferor. However, the absence of such confirmation shall not affect the
validity of such notice. If the written confirmation differs in any material
respect from the action taken by the Company or the Agent, the records of the
Company or the Agent, as applicable shall govern absent manifest error.
