         in clause (i) thereof.

                           (c) the definition of "Permitted Liens" is hereby
         amended by deleting the "and" at the end of clause (xiv), replacing the

         the end thereof as a new clause (xvi) thereto:

                           "(xvi) Liens created or deemed to exist by the

<PAGE>   33
Transfer to be made to the Agent on behalf of such Person. To the extent that

Investor, such Conduit Investor 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 each Conduit Investor and each Bank Investor against any loss or
expense incurred by any Conduit Investor or any Bank Investor, either directly
or indirectly (including, in the case of a Conduit Investor, through the related
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 any Conduit Investor or any Bank Investor, either directly or

Incremental Transfers.

            By no later than 11:00 a.m. (New York time) on any Transfer Date,
each Investor participating in the relevant Transfer shall remit its Ratable
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
Investor. The obligation of each Investor to remit its Ratable Share of any such
Transfer Price shall be several from that of each other Investor, and the
failure of any Investor to so make such amount available to the Agent shall not
relieve any other Investor of its obligation hereunder. Following each
Incremental Transfer and the Agent's receipt of funds from the Investors
participating in such Transfer 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
any Bank Investor participating in an Incremental Transfer that such Bank
Investor will not make its share of any Transfer Price relating to such
Incremental Transfer available on the applicable Transfer Date therefor, the
Agent may (but shall have no obligation to) make 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 such Bank Investor. To the extent such
Bank Investor fails to remit any such amount to the Agent after any

                                       35
<PAGE>   34
such advance by the Agent on such Transfer Date, 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 such Bank Investor, or the Base Rate, in the case
of the Transferor, to the Agent upon its demand therefor. 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 such Bank Investor, such payment shall constitute such Bank Investor'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 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 Percentage Factor at an amount not
greater than the Maximum Percentage Factor, the Agent may, on behalf of each
Conduit Investor (unless such Conduit Investor has otherwise directed the Agent)
and shall, on behalf of each of the Bank Investors, 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 applicable Investors, 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 applicable Investors, shall equal the
Percentage Factor in effect from time to time. The Agent shall hold the
Transferred Interests on behalf of the applicable Investors in accordance with
each such 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 Investor bears to the aggregate Net Investment of all Investors at such
time).

                  (d) Certificate. The Transferor has issued to the Agent the
Certificate, in the form of the Exhibit M. The Certificate remains in full force

the effective date of this Agreement. 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 a Conduit Investor. At all times hereafter, but prior to the
Termination Date with respect to any portion of the Transferred Interest held on
behalf of a Conduit Investor, the Transferor may, subject to such Conduit
Investor's approval and the limitations described below, request Tranche Periods
and allocate a portion of the Net Investment held by such Conduit Investor to
each selected Tranche Period, so that the aggregate amounts allocated to
outstanding Tranche Periods with respect to such Conduit Investor at all times
shall equal the Net Investment held on behalf of such Conduit Investor. The
Transferor shall give each Conduit Investor irrevocable notice by telephone of
the new requested Tranche Period(s) applicable to such Conduit Investor at least
three (3) Business Days prior to the expiration of any then existing Tranche
Period with respect to such Conduit Investor; provided, however, that each
Conduit Investor 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)
such Conduit Investor determines, in its sole discretion, that the Tranche
Period requested by the Transferor is unavailable or for any reason commercially
undesirable. Each Conduit Investor 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 such Conduit Investor 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 any Liquidity Provider acquires from a Conduit Investor a Purchased
Interest with respect to the Receivables pursuant to the terms of a Liquidity
Provider Agreement, then the Administrative Agent for such Conduit Investor, on
behalf of the applicable Liquidity Provider, may exercise the right of selection
granted to such Conduit Investor 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

                                       37
<PAGE>   36
Rate, as determined by the applicable Administrative Agent. In the case of any
Tranche Period outstanding upon the Termination Date, such Tranche Period shall
end on such date.

                  (b) After the Termination Date; Transferred Interest Held on
behalf of a Conduit Investor. 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 a Conduit Investor, such Conduit Investor or its
Administrative Agent, 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 in any
Related Group, 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) in any Related Group, 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 Administrative Agent for each Related Group irrevocable notice by telephone
of the new requested Tranche Period applicable to the Bank Investors in such
Related Group at least three (3) Business Days prior to the expiration of any
then existing Tranche Period applicable to such Related Group and, if the
Transferor shall fail to provide such notice, the applicable Administrative
Agent on behalf of the Bank Investors in such Related Group 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 in any Related Group, the Administrative Agent for such
Related Group shall select all Tranche Periods and Tranche Rates applicable
thereto.

                  (e) Eurodollar Rate Protection; Illegality. (i) If the
Administrative Agent for any Related Group is unable to obtain on a timely basis
the information necessary to determine the LIBOR Rate for any proposed
Eurodollar Tranche, then

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

            (B) while such circumstances exist, neither such Administrative
      Agent nor any of the Investors in such Related Group 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.

                                       38
<PAGE>   37
            (ii) If, with respect to any outstanding Eurodollar Tranche, any
Investor on behalf of which the Agent holds any Transferred Interest therein
notifies its Administrative 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 such Investor of funding or
maintaining its respective Transferred Interest for such Tranche Period then
such Administrative Agent shall forthwith so notify the Transferor, whereupon
neither such Administrative Agent nor the Conduit Investor or the Bank Investors
in the Related Group, 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 any
Investor shall notify its Administrative Agent that such Investor 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 such Investor or such Liquidity Provider, as applicable), or any
central bank or other governmental authority asserts that it is unlawful, for
such 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 Investor to its Administrative
Agent, the obligation or ability of the such Investor to fund its purchase or
maintenance of Transferred Interests at the Eurodollar Rate shall be suspended
until such Investor notifies its Administrative Agent that the circumstances
causing such suspension no longer exist and (y) the Net Investment of each
Eurodollar Tranche in which such Investor owns an interest shall either (1) if
such Investor 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 Investor 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 Investor'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.

            (f) Separate Tranches for Related Groups. In no event shall portions
of the Net Investment held by Investors from different Related Groups be
allocated to the same Tranche.

            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 any Conduit Investor 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 each Administrative Agent, on behalf of the applicable Investors in its
Related Group, 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 a Conduit Investor, an amount equal to the discount accrued on the
Commercial Paper of such Conduit Investor or its Related CP Issuer to the extent

                                       39
<PAGE>   38
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 each Administrative Agent, on behalf of the applicable
Conduit Investor, on each day on which Related Commercial Paper is issued by
such Conduit Investor or its Related CP Issuer (or, if so provided in the
applicable Fee Letter, on the last day of each Tranche Period), 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.

            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 applicable Investors (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 applicable Investors, to the purchase of additional undivided percentage
interests in each Receivable pursuant to Section 2.2(b) hereof. Any Collections
so set aside as described in clause (i) above shall be allocated among the
Related Groups ratably in proportion to the accrued Discount and Servicing Fee
with respect to the Investors in each such Related Group. On the last day of
each Tranche Period applicable to any portion of the Net Investment held by one
or more Investors in a Related Group, from the amounts set aside as described in
clause (i) of the first sentence of this Section 2.5 hereof that have been
allocated to the Investors in such Related Group, the Collection Agent shall
deposit to the applicable Administrative Agent's account, for the benefit of
such Investors, 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 applicable
Administrative Agent, upon its receipt of such amounts in such Administrative
Agent's account, shall distribute such amounts to the applicable Conduit
Investor and/or the applicable Bank Investors entitled thereto as set forth
above; provided that if such Administrative Agent shall have insufficient funds
to pay all of the above amounts in full on any such date, such Administrative
Agent shall pay such amounts ratably (based on the amounts owing to each such
Investor) to all such Investors 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 the
applicable Investors.

            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
Administrative Agents, for the benefit of the applicable Investors in their
respective Related Groups, from previously received Collections, an aggregate
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 aggregate amount shall be paid to the Administrative
Agents ratably in accordance with portion of the Net Investment held by their
respective Related Groups. Any amount so paid

                                       40
<PAGE>   39
to an Administrative Agent for a Related Group shall be applied to the reduction
of the Net Investment of Tranche Periods applicable to such Related Group
selected by such Administrative 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 applicable Investors (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 applicable Investors. The Collections
so set aside shall be allocated among the Related Groups ratably in accordance
with the portion of the Net Investment held by each such Related Group. 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 each Administrative Agent's account, for the benefit of the
applicable Investors, any amounts set aside pursuant to Section 2.5 above which
have been allocated to such Administrative Agent's Related Group as described in
Section 2.5. 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 each Administrative
Agent's account to the extent not already so deposited, for the benefit of the
applicable Investors in its Related Group, the amounts so set aside that have
been allocated to the Investors in such Related Group pursuant to this Section
2.6, 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 so allocated to the Investors in such
Related Group pursuant to the preceding sentence which remain after payment in
full of the aforementioned amounts, the accrued Servicing Fee for such Tranche
Period. If with respect to any Tranche Period 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 for such Tranche Period, 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 payment of the
Servicing Fee payable to the Collection Agent to the extent allocable to such
Tranche Period, third, in reduction of the Net Investment allocated to such
Tranche Period fourth, in payment of all fees payable by the Transferor
hereunder to the members of the relevant Related Group, fifth, in payment of all
other Aggregate Unpaids owing to the members of such Related Group 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 to the extent such
Servicing Fee is allocable to such Tranche Period. The applicable Administrative
Agent, upon its receipt of such amounts in such Administrative Agent's account,
shall distribute such amounts to the Investors in its Related Group entitled
thereto as set forth above; provided that if such Administrative Agent shall
have insufficient funds to pay all of the above amounts in full on any such
date, such Administrative Agent shall pay such amounts in the order of priority
set forth above and, with respect to any such category above for which such
Administrative 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.

                                       41
<PAGE>   40
            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 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 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.

            SECTION 2.7. Fees. Notwithstanding any limitation on recourse
contained in this Agreement, on the last day of each month the Transferor shall
pay the following non-refundable fees: (i) to each Conduit Investor solely for
its own account, the Program Fee with respect to such Conduit Investor, (ii) to
each Conduit Investor the Facility Fee with respect to the applicable Related
Group for distribution to the Bank Investors in such Related Group and (iii) to
Enterprise the Administrative Fee.

            SECTION 2.8. Protection of Ownership Interest of the 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 or any Administrative Agent may reasonably request in
order to perfect or protect the Transferred Interest or to enable the Agent, the
Administrative Agents or the 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, any
Administrative Agent or any of the 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, any
Administrative Agent or any of the 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 Investors, of the Transferred Interest. The
Transferor shall, and will cause the Seller to, upon request of the Agent, any
Administrative Agent or any of the Investors obtain such additional search
reports as the Agent, any Administrative Agent or any of the 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 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 and each Administrative Agent at least thirty (30) days prior notice
thereof and (ii) prepared at Transferor's expense and

                                       42
<PAGE>   41
delivered to the Agent all financing statements, instruments and other documents
necessary to preserve and protect the Transferred Interest or requested by the
Agent or any Administrative 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, any Administrative Agent or
any of the 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
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 each
Administrative Agent, and the Transferor, the Agent and each Administrative
Agent shall commence discussions with a view toward implementing an alternative
arrangement therefor satisfactory to the Agent and each Administrative 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.

                                       43
<PAGE>   42
                  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 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 applicable Administrative 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 or any of the 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 applicable
Administrative 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 each Administrative 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 City time) on the day when due in immediately available funds; if
such amounts are payable to the Agent or any Administrative Agent (whether on
behalf of any of the Investors or otherwise) they shall be paid or deposited in
the applicable account indicated in Section 10.3 hereof, until otherwise
notified by the Agent or such Administrative Agent, as the case may be. The
Transferor shall, to the extent permitted by law, pay to each Administrative
Agent, for the benefit of itself and the Investors in its Related Group, upon
demand, interest on all amounts owing to such Administrative Agent or such
Investors not 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 an Administrative

                                       44
<PAGE>   43
Agent of amounts payable by the Transferor hereunder to such Administrative
Agent or any Investor in its Related Group 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 each
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 any
Administrative Agent may reasonably request.

                  SECTION 2.12. Collection Account. The Collection Agent has
established and shall maintain 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
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 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

Affiliates). The Seller has given reasonably equivalent value to each
Transferring Affiliate in consideration for each transfer to the Seller of
Receivables and Related Security from such Transferring Affiliate, and no such
transfer has been made for or on account of an antecedent debt owed by such

Each of the representations and warranties of the Seller set forth in Section
3.1 of the Receivables Purchase Agreement are true and correct in all material
respects and the Transferor hereby remakes all such representations and
warranties for the benefit of the Agent, each of the Investors and each
Administrative Agent.

                           (aa) Year 2000 Compliance. The Transferor has (i)
initiated a review and assessment of all areas within its and each of its
Subsidiaries' business and operations (including those affected by suppliers,
vendors and customers) that could be adversely affected by the `Year 2000
Problem' (that is, the risk that computer applications used by the Transferor or
any of its Subsidiaries (or suppliers, vendors and customers) may be unable to
recognize and perform properly date-sensitive functions involving certain dates
prior to and any date after December 31, 1999), (ii) initiated the development
of a plan and timeline for addressing the Year 2000 Problem on a timely basis,
and (iii) to date, implemented that plan in accordance with that timetable. The
Transferor believes that all computer applications (including those of its
suppliers, vendors and customers) that are material to its or any of its
Subsidiaries' business and operations are reasonably expected on a timely basis
to be able to perform properly date-sensitive functions for all dates before and
after January 1, 2000 (that is, be `Year 2000 Compliant'), except to the extent
that a failure to do so could not reasonably be expected (a) to have a Material
Adverse Effect on the Transferor or on the transaction documented under this
Agreement, or (b) to result in a Termination Event.

                  The Transferor (i) has initiated a review and assessment of
all computer applications (including, but not limited to, those of the
Transferor, the Collection Agent, the Seller, any Transferring Affiliate and any
of their respective suppliers, vendors, customers or third party servicers),
which are related to or involved in the origination, collection, management or
servicing of the Receivables (the `Receivable Systems') and (ii) believes that
such Receivable Systems are Year 2000 Compliant or will be Year 2000 Compliant
on or before April 1, 1999 and thereafter.

                  The Transferor believes that the costs of all assessment,
remediation, testing and integration related to the Transferor's plan for
becoming Year 2000 Compliant will not have a material adverse effect on the
financial condition or operations of the Transferor.

                  Any document, instrument, certificate or notice delivered by
the Transferor to any Conduit Investor, Administrative Agent or the Agent
hereunder shall be deemed a representation and warranty by the Transferor.

                  SECTION 3.2. Reaffirmation of Representations and Warranties

         and each Administrative Agent, a completed Investor Report dated within
         ten (10) days prior to the date of such Incremental Transfer, together
         with a listing by Primary Payor of all Receivables, and such additional
         information as may be reasonably requested by any Administrative Agent
         or the Agent;

                           (b) on date of such Incremental Transfer, either (i)
         FMCH's long-term public senior debt securities are rated as least B- by
         Standard & Poor's and B3 by Moody's, or if neither Standard & Poor's
         nor Moody's shall rate such securities, FMCH's long-term senior debt
         shall have a deemed rating of at least B as determined by each
         Administrative Agent using its standard bond rating methodology, or
         (ii) FMC's long-term public senior debt securities are rated as least
         B- by Standard & Poor's and B3 by Moody's Investors Service, or if
         neither Standard & Poor's nor Moody's shall rate such securities, FMC's
         long-term senior debt shall have deemed rating of at least B as
         determined by each Administrative Agent using its standard bond rating
         methodology,

of this Agreement are within the Collection Agent's corporate powers, have been
duly authorized by all necessary corporate action, require no action by or in
respect of, or filing with, any Official Body or official thereof, and do not

Accounts or Concentration Account or with such other Designated Account Agents
as have been notified to the Agent in accordance with Section 5.2(e)).

                           (l) Year 2000 Compliance. The Collection Agent has
(i) initiated a review and assessment of all areas within its, the Seller's and
each Transferring Affiliate's business and operations (including those affected
by suppliers, vendors and customers) that could be adversely affected by the
`Year 2000 Problem' (that is, the risk that computer applications used by the
Collection Agent, the Seller or any Transferring Affiliate (or suppliers,
vendors and customers) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999), (ii) initiated the development of a plan and timeline for
addressing the Year 2000 Problem on a timely basis, and (iii) to date,
implemented that plan in accordance with that timetable. The Collection Agent
believes that all computer applications (including those of its suppliers,
vendors and customers) that are material to its, the Seller's or any
Transferring Affiliate's business and operations are reasonably expected on a
timely basis to be Year 2000 Compliant, except to the extent that a failure to
do so could not reasonably be expected (a) to have a Material Adverse Effect on
the Collection Agent, the Seller or any Transferring Affiliate or on the
transactions contemplated by the Transaction Documents, or (b) to result in a
Termination Event.

                  The Collection Agent (i) has initiated a review and assessment
of all Receivable Systems and (ii) believes that such Receivable Systems are
Year 2000 Compliant or will be Year 2000 Compliant on or before April 1, 1999
and thereafter.

                  The Collection Agent believes that the costs of all
assessment, remediation, testing and integration related to the Collection
Agent's plan for becoming, and causing the Seller and each Transferring
Affiliate to become, Year 2000 Compliant will not have a material adverse effect
on the financial condition or operations of the Collection Agent, the Seller or
any Transferring Affiliate.

Conduit Investor or its Related CP Issuer, provided that the Person making such

Accounts at such Special Account Bank, and (vi) instruct the Concentration
Account Bank to give to each Special Account Bank on each banking day notice to
transfer to the Concentration Account all Collections on deposit during such
banking day in the Special Accounts at such Special Account Bank; provided,
however, that if the Collections on deposit in any Special Account during such
banking day shall be less than $5,000.00 (the "Minimum Amount"), the Special
Account Bank shall transfer such Collections to the Concentration Account on the
next succeeding banking day on which Collections in such Special Account first
exceed the Minimum Amount. With respect to any

                                       60

Receivables Purchase Agreement, the Transferring Affiliate Letter or the BMA
Transfer Agreement in any manner other than as a sale of Receivables by the
applicable Originating Entity to the Seller or Transferor, as applicable, or
(ii) account for (other than for tax purposes) or otherwise treat and
transactions contemplated hereby in any manner other than as a sale of
Receivables by the Transferor to the Agent on behalf of the applicable
Investors. In addition, the Transferor shall, and shall cause each Originating
Entity to, disclose (in a footnote or otherwise) in all of its respective
financial statements (including any such financial statements consolidated with
any other Persons' financial statements) the existence and nature of the
transaction contemplated hereby, by the Receivables Purchase Agreement, by the
Transferring Affiliate Letter and by the BMA Transfer Agreement, and the
interest of the Transferor (in the case of the Seller's financial statements),
and the Agent, on behalf of the Investors, in the Affected Assets.

and pay its own liabilities, including all administrative expenses, from its own
separate assets, except that the Seller may pay the organizational expenses of

Transfer under this Agreement and relating to "non-consolidation" issues and
"true sale" issues, and in the certificates accompanying such opinions, remain

amend, alter, change or repeal any provision of the Third, Fifth, Seventh,
Tenth, Eleventh or Twelfth Article of its Certificate of Incorporation with the
prior written consent of each Administrative Agent.

                           (m) Payment to the Originating Entities. With respect
to any Receivable purchased by the Transferor from the Seller, such sale shall
be effected under, and in strict compliance with the terms of, the Receivables
Purchase Agreement, including, without limitation, the terms relating to the

with the terms of, the Transferring Affiliate Letter and the BMA Transfer
Agreement, as applicable, including, without limitation, the terms relating to
the amount and timing of payments to be made to each Transferring Affiliate in

to vigorously enforce the rights and remedies accorded to the Seller, under each
of the Transferring Affiliate Letter and the BMA Transfer Agreement. The
Transferor shall take all actions to perfect and enforce its rights and
interests (and the rights and interests of the Agent, each Administrative Agent
and each of the Investors, as assignees of the Transferor) under the Receivables
Purchase Agreement as any Administrative Agent may from time to time reasonably
request, including, without limitation, making claims to which it may be
entitled under any indemnity, reimbursement or similar provision contained in
the Receivables Purchase Agreement. The Transferor shall cause the Seller to
take all actions to perfect and enforce the Seller's rights and interests (and
the rights and interests of the Transferor, the Agent, the

<PAGE>   61
Administrative Agent and each of the Investors, as assignees of the Seller)

indemnity, reimbursement or similar provision contained in the Transferring
Affiliate Letter or the BMA Transfer Agreement.

                  (o) Year 2000 Compliance: Reporting. The Transferor will
promptly notify each Administrative Agent in the event the Transferor discovers

vendors and customers) (i) that is necessary for the origination, collection,
management, or servicing of the Receivables will not be Year 2000 Compliant on
or before April 1, 1999 and thereafter, or (ii) that is otherwise material to
its or any of its Subsidiaries' business and operations will not be Year 2000
Compliant on a timely basis, except to the extent that, in the case of (ii)
above, such failure could not reasonably be expected (a) to have a Material
Adverse Effect on the Transferor or on the transaction documented under this
Agreement, or (b) to result in a Termination Event.

                  Further, the Transferor will deliver to each Administrative
Agent simultaneously with any quarterly or annual financial statements or
reports to be delivered under the Agreement, a certificate signed by an officer
of the Transferor that no material event, problems or conditions have occurred
which in the opinion of management would (i) prevent or materially delay the
Transferor's plan to become Year 2000 Compliant or (ii) cause or be likely to
cause the Transferor's representations and warranties or covenants with respect
to being or becoming Year 2000 Compliant to no longer be true.

                  (p) Year 2000 Compliance: Implementation: The Transferor will

and customers) that are material to its or any of its Subsidiaries' business and
operations to be Year 2000 Compliant on a timely basis, except to the extent

Adverse Effect on the Transferor or on the transaction documented under this
Agreement, or (b) to result in a Termination Event; and (ii) all Receivable
Systems to be Year 2000 Compliant at all times on and after April 1, 1999. The
Transferor will deliver a certificate to each Administrative Agent, signed by

may give rise to a Receivable or any Receivable or related Contract, or (z) any
Special Account or the

the Transaction Documents) to any Person, except that (i) any Transferring
Affiliate may merge or consolidate with any other Transferring Affiliate if, but
only if, each Administrative Agent shall receive at least ten Business Days'
prior written notice of such merger or consolidation and (ii) the Seller may
merge or consolidate with any other Person if, but only if, (x) immediately
after giving effect to such merger or consolidation, no Termination Event or
Potential Termination Event would exist and (y) each Administrative Agent shall

Interest hereunder.

     SECTION 6.2. Duties of Collection Agent.

         (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 Agent, the
Administrative Agents and the 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

                                       70
<PAGE>   69

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 (for the benefit of
the Investors) 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 each Administrative Agent's account such
Administrative 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 trust for the Transferor, and the Agent, on
behalf of the 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, any
Administrative Agent or any of the 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 each Administrative 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 or for the benefit of any of the
Investors hereunder. 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 Bank of America, N.A. or such other Person as may be approved by each
Administrative Agent, to furnish a report to each Administrative 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

                                       71
<PAGE>   70

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 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.

                                       72
<PAGE>   71

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.

the following events shall constitute a Collection Agent Default:

any Official Body (in the case of any bank regulatory guideline, whether or not
having the force of Law):

     Transferred Interest, the Receivables or payments of amounts due hereunder,

          (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 a Liquidity Provider

     the ownership, maintenance or financing of the Transferred Interest or the

          (iii) imposes upon any Indemnified Party any other expense (including,

                                       81
<PAGE>   80

     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 a Liquidity
     Provider Agreement or the credit support furnished by a 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, a Liquidity Provider Agreement or a
     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 any
Administrative Agent, the Transferor shall pay to such Administrative 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 any
Administrative Agent, the Transferor shall pay to such Administrative 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.

         (c) Each Administrative 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 an Administrative Agent 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, such Administrative 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 a
Conduit Investor enters into agreements for the acquisition of interests in
receivables from one or more Other Transferors, such Conduit Investor shall
allocate the liability for any amounts under this Section 8.2 which are in
connection with a Credit Support Agreement or the credit support provided by the
Credit Support Provider or, in the case of Enterprise, the Liquidity Provider
Agreement to which Enterprise is a party ("Section 8.2 Costs") to the Transferor
and each Other

                                       82
<PAGE>   81

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 any Investor, any Administrative Agent
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 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 each Administrative Agent an official receipt
or other documentation satisfactory to the Administrative 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.

                                       83
<PAGE>   82

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

          (X) (i) on or before the date of any payment by a Payor to such
     Investor, deliver to such Payor, the Agent and the Administrative Agent for
     its Related Group (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, the Agent and the Administrative Agent for
     its Related Group 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, the
     Agent or the Administrative Agent for its Related Group; or

          (Y) Each 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, the Agent and the
     Administrative Agent for its Related Group (i) a statement under penalties
     of perjury that such 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 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, the Agent and its Administrative 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

                                       84
<PAGE>   83

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

unless in any such case any change in treaty, law or regulation has occurred
after the date such Person becomes an Investor hereunder which renders all such
forms inapplicable or which would prevent such Investor from duly completing and
delivering any such form with respect to it and such Investor so advises each
Payor, the Agent and its Administrative Agent. Each Person that shall become an
Investor or a participant of an 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 an Investor the obligations of
such participant of an Investor pursuant to this subsection (b) shall be
determined as if the participant of an Investor were an Investor except that
such participant of an Investor shall furnish all such required forms,
certifications and statements to the 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 Investors, the Administrative Agents 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
expenses, any filing fees and expenses incurred by officers or employees of any
of the Investors, the Administrative Agents and/or the Agent) or intangible,
documentary or recording taxes incurred by or on behalf of any Investor, any
Administrative Agent or the Agent (i) in connection with the negotiation,
execution, delivery and preparation of this Agreement, the other Transaction
Documents and any documents or instruments delivered pursuant hereto and thereto
and the transactions contemplated hereby 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, (b) arising in connection with
any Investor's, any Administrative Agent's, the Agent's or any Collateral
Agent's enforcement or preservation of rights (including, without limitation,
the perfection and protection of the Transferred Interest under this Agreement),
or (c) arising in connection with any audit, dispute, disagreement, litigation
or preparation for litigation involving this Agreement or any of the other
Transaction Documents (all of such amounts, collectively, "Transaction Costs").

         (b) With respect to any Tranche to which all or any portion of the Net
Investment held by any of the Investors in a Related Group has been allocated,
the Transferor shall pay to the Administrative Agent for such Related Group, for
the account of each applicable Investor, on demand any Early Collection Fee due
on account of the reduction of such 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 applicable
Investors, of the Transferred Interest if the Agent or any Administrative Agent
notifies Transferor of a material breach of any representation or warranty made
or deemed made pursuant to Article III of this Agreement and Transferor shall
fail to cure such breach within 15 days (or, in the case of the

                                       85
<PAGE>   84

representations and warranties in Sections 3.1(d) and 3.1(j), 3 days) of such
notice. The reconveyance price shall be paid by the Transferor to the Agent, for
the account of the applicable Investors, as applicable, in immediately available
funds on such 15th day (or 3rd day, if applicable) in an amount equal to the
Aggregate Unpaids; provided that if such 15th day (or 3rd day) is not a Business
Day, such reconveyance and the related payment shall be made on the next
following Business Day.

                                   ARTICLE IX

              THE AGENT; BANK COMMITMENT; THE ADMINISTRATIVE AGENTS

     SECTION 9.1. Authorization and Action. (a) Each Investor hereby appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement and the other 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, each 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 any 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 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, 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

                                       86
<PAGE>   85

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, without the prior written consent of each
Administrative Agent, agree to amend, modify or waive any provision of this
Agreement, the Transferring Affiliate Letter, the BMA Transfer Agreement, the
Receivables Purchase Agreement or the Parent Agreement. 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 any Investor's consent pursuant to the
foregoing provisions and the Agent does not receive a consent (either positive
or negative) from such Investor within 10 Business Days of such Investor's
receipt of such request, then such 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, 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 any Investor and shall not
be responsible to any 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 any 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. Each Investor acknowledges that it has,
independently and without reliance upon the Agent, any Administrative Agent, any
Affiliate of an Administrative Agent or any other 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. Each Investor also acknowledges that it will, independently and
without reliance upon the Agent, any of the Agent's Affiliates or any other
Investor and based on such documents and information as it shall deem
appropriate at the time, continue to make its own 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 Ratable 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 Ratable 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 Investor and the Transferor and may be removed at
any time with cause by the Majority Investors. Upon any such resignation or
removal, the Majority Investors shall appoint a successor Agent. Each 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'
removal of the retiring Agent, then the retiring Agent may, on behalf of the
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

                                       88
<PAGE>   87

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 an
Investor pursuant to the terms of this Agreement, all amounts received by the
Agent on behalf of the Investors shall be paid by the Agent to the 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
Investors on such Business Day, but, in any event, shall pay such amounts to the
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 a Conduit Investor 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 such Conduit Investor to assign its
interest in the Net Investment in whole to the Bank Investors in its Related
Group pursuant to this Section 9.7. In addition, at any time on or prior to the
Commitment Termination Date, (i) upon the occurrence of a Termination Event that
results in the Termination Date or (ii) if a Conduit Investor elects to give
notice to the Transferor of a Reinvestment Termination Date, the Transferor
hereby requests and directs that such Conduit Investor assign its interest in
the Net Investment in whole to the Bank Investors in its Related Group 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 a Conduit Investor or any such request by
the Transferor to such Conduit Investor, such Conduit Investor shall make such
assignment and the Bank Investors in its Related Group shall accept such
assignment and shall assume all of such Conduit Investor's obligations
hereunder. In connection with any assignment from a Conduit Investor to the Bank
Investors in its Related Group pursuant to this Section 9.7, each Bank Investor
shall, on the date of such assignment, pay to such Conduit Investor an amount
equal to its Assignment Amount. Upon any assignment by a Conduit Investor to the
Bank Investors in its Related Group as contemplated hereunder, such Conduit
Investor 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
for its Related Group, on behalf of the related Conduit Investor. In the case of
an assignment by a Conduit Investor 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

                                       89
<PAGE>   88

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 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 related Conduit Investor 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 related Conduit Investor 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, the
Administrative Agent for the applicable Related Group and the Transferor. All
costs and expenses of the Agent, the applicable Administrative 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 applicable
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 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, any Administrative Agent, or any of their
respective 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

                                       90
<PAGE>   89

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 appoints and authorizes
the applicable Administrative 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 Administrative 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, (vii) 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 (viii) such assignee agrees that it will not institute
against any Conduit Investor 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 such Conduit Investor or its Related CP
Issuer.

         (d) Transferor's Obligation to Pay Certain Amounts; Additional
Assignment Amount. The Transferor shall pay to the Administrative Agent for a
Conduit Investor, for the account of such Conduit Investor, in connection with
any assignment by such Conduit Investor to the Bank Investors in its Related
Group 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) owing to such Conduit
Investor. To the extent that such Discount relates to interest or discount on
Related Commercial Paper, if the Transferor fails to make payment of such
amounts at or prior to the time of assignment by such Conduit Investor to the
Bank Investors in its Related Group, such amount shall be paid by such Bank
Investors (in accordance with their respective Pro Rata Shares) to such Conduit
Investor as additional consideration for the interests assigned to such Bank
Investors and the amount of the "Net Investment" hereunder held by such Bank
Investors shall be increased by an amount equal to the additional amount so paid
by such Bank Investors.

         (e) Administration of Agreement After Assignment. After any assignment
by a Conduit Investor to the Bank Investors in its Related Group pursuant to
this Section 9.7 (and the payment of all amounts owing to such Conduit Investor
in connection therewith), all rights of the related Collateral Agent set forth
herein shall be deemed to be afforded to the Administrative Agent for such
Related Group on behalf of such Bank Investors instead of such Collateral Agent.

         (f) Payments. After any assignment by a Conduit Investor to the Bank
Investors in its Related Group pursuant to this Section 9.7, all payments to be
made hereunder by the Transferor or the Collection Agent to such Conduit
Investor shall be made to the applicable Administrative Agent's account as such
account shall have been notified to the Transferor and the Collection Agent.

                                       91
<PAGE>   90

         (g) Downgrade of Bank Investor. If (at any time prior to any assignment
by a Conduit Investor to the Bank Investors in its Related Group as contemplated
pursuant to this Section 9.7) the short term debt rating of any Bank Investor in
such Related Group 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 applicable Administrative 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 in a Related Group 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 applicable Administrative 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 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 in a Related Group shall not have assigned its rights and
obligations under this Agreement within the applicable time period described
above, the related Conduit Investor 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
such Conduit Investor, 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
applicable Administrative 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 applicable Related Group Limit, solely as it relates to
new Incremental Transfers to such Conduit Investor, 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.

     SECTION 9.8. Appointment of Administrative Agents. (a) Each Investor in a
Related Group hereby appoints and authorizes the Administrative Agent for its
Related Group to take such action as agent on its behalf and to exercise such
powers under this Agreement and the other Transaction Documents as are delegated
to such Administrative 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, each Investor in a Related Group
hereby appoints the Administrative Agent for its Related Group as its agent to
execute and deliver all further instruments and documents, and take all further
action that such Administrative Agent may deem necessary or appropriate or that
any Investor may reasonably request to enable any of them to exercise or enforce
any of their respective rights hereunder. Bank Investors representing at least
66 and 2/3% of the aggregate Commitments of all Bank Investors in a Related
Group (the "Group Majority Investors") may direct the Administrative Agent for
such Related Group to take any such incidental action hereunder. With respect to
other actions which are incidental to the

                                       92
<PAGE>   91

actions specifically delegated to an Administrative Agent hereunder, such
Administrative 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
Group Majority Investors; provided, however, no Administrative Agent shall be
required to take any action hereunder if the taking of such action, in the
reasonable determination of such Administrative Agent, shall be in violation of
any applicable law, rule or regulation or contrary to any provision of this
Agreement or shall expose such Administrative Agent to liability hereunder or
otherwise. Upon the occurrence and during the continuance of any Termination
Event or Potential Termination Event, the Administrative Agent for a Related
Group shall take no action hereunder (other than ministerial actions or such
actions as are specifically provided for herein) without the prior consent of
the Group Majority Investors (which consent shall not be unreasonably withheld
or delayed). The Administrative Agent for a Related Group shall not, without the
prior written consent of all Bank Investors in such Related Group, 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 in such Related Group 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 in such Related Group. The Administrative Agent for a Related
Group shall not agree to any amendment of this Agreement which increases the
dollar amount of the Commitment of a Bank Investor in such Related Group without
the prior consent of such Bank Investor. In addition, no Administrative Agent
shall agree to any amendment of this Agreement not specifically described in the
two preceding sentences without the consent of the related Group Majority
Investors (which consent shall not be unreasonably withheld or delayed). In the
event an Administrative Agent requests any Investor's consent pursuant to the
foregoing provisions and such Administrative Agent does not receive a consent
(either positive or negative) from such Investor within 10 Business Days of such
Investor's receipt of such request, then such Investor (and its percentage
interest hereunder) shall be disregarded in determining whether such
Administrative Agent shall have obtained sufficient consent hereunder.

         (b) Each Administrative 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 9.9. Administrative Agent's Reliance, Etc. Neither any
Administrative Agent nor any directors, officers, agents or employees of an
Administrative Agent shall be liable for any action taken or omitted to be taken
by it or them as Administrative Agent under or in connection with this Agreement
or any of the other Transaction Documents, except for its or their own gross
negligence or willful misconduct. Without limiting the foregoing, each

                                       93
<PAGE>   92

Administrative 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 any Investor
and shall not be responsible to any 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 any
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 9.10. Indemnification of the Administrative Agents. The Bank
Investors in each Related Group agree to indemnify the Administrative Agent for
such Related Group (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 such Administrative Agent in any way
relating to or arising out of this Agreement or any action taken or omitted by
such Administrative Agent, any of the other Transaction Documents hereunder or
thereunder, provided that the Bank Investors in a Related Group shall not be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from the applicable Administrative Agent's gross negligence or willful
misconduct. Without limitation of the foregoing, the Bank Investors in each
Related Group agree to reimburse the Administrative Agent for such Related
Group, ratably in accordance with their Pro Rata Shares, promptly upon demand
for any out-of-pocket expenses (including counsel fees) incurred by such
Administrative 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 such Bank
Investors hereunder and/or thereunder and to the extent that such Administrative
Agent is not reimbursed for such expenses by the Transferor.

     SECTION 9.11. Successor Administrative Agents. Any Administrative Agent may
resign at any time by giving written notice thereof to the Agent, each Investor
in its Related Group and the Transferor and may be removed at any time with
cause by the applicable Group Majority Investors. Upon any such resignation or
removal, the Group Majority Investors for such Related Group shall appoint a
successor Administrative Agent. Each Investor agrees that it shall not
unreasonably withhold or delay its approval of the appointment of a successor
Administrative Agent. If no such successor Adminisrative Agent shall have been
so appointed for such Related Group, and shall have accepted such appointment,
within 30 days after the

                                       94
<PAGE>   93

retiring Administrative Agent's giving of notice of resignation or the Group
Majority Investors' removal of the retiring Administrative Agent, then the
retiring Administrative Agent may, on behalf of the Investors in such Related
Group, appoint a successor Administrative Agent for such Related Group which
successor Administrative Agent shall be either (i) a commercial bank having 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 Administrative Agent
hereunder by a successor Administrative Agent, such successor Administrative
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations under
this Agreement. After any retiring Administrative Agent's resignation or removal
hereunder as Administrative 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 Administrative Agent under this Agreement.

     SECTION 9.12. Payments by the Administrative Agents. Unless specifically
allocated to an Investor pursuant to the terms of this Agreement, all amounts
received by an Administrative Agent on behalf of the Investors in its Related
Group shall be paid by such Administrative Agent to the Investors in its Related
Group (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 such
Administrative Agent, unless such amounts are received after 12:00 noon on such
Business Day, in which case such Administrative Agent shall use its reasonable
efforts to pay such amounts to the Investors in its Related Group on such
Business Day, but, in any event, shall pay such amounts to such Investors in
accordance with their respective related pro rata interests in the Net
Investment not later than the following Business Day.

                                    ARTICLE X

                                  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 Investors and the
Administrative Agents 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, any Investor or any Administrative Agent 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

                                       95
<PAGE>   94

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 Agent, each Administrative Agent and the Majority Investors and
in the case of any waiver, such waiver is granted in writing by each
Administrative 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 10.3 and confirmation is received,
(ii) if given by mail 3 Business Days following such posting, postage prepaid,
U.S. certified or registered, (iii) if 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 each Investor, each Administrative Agent and
the Agent to effect Transfers, Tranche Period and Tranche Rate selections based
on telephonic notices made by any Person which such Investor, such
Administrative Agent or the Agent, as applicable, in good faith believes to be
acting on behalf of the Transferor. The Transferor agrees to deliver promptly to
each such Investor or Administrative Agent or the Agent, as applicable, a
written confirmation of each telephonic notice directed to such Person 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 Agent or the
applicable Investor or Administrative Agent, the records of such Investor or
Administrative Agent or the Agent, as applicable shall govern absent manifest
error.

AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. Each of the Transferor and
the Collection Agent hereby irrevocably waives, to the fullest extent it may
effectively do so, any objection which it may now or hereafter have to the
laying of the venue of any such proceeding brought in such a court and any claim
that any such proceeding brought in such a court has been brought in an
inconvenient forum. Nothing in this

     SECTION 10.5. Severability; Counterparts. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate

hereby constitute the sale of the Transferred Interest, conveying good title
thereto free and clear of any Adverse Claims to the Agent, on behalf of the
Investors, and that the Transferred Interest not be part of the Transferor's
estate in the event of an insolvency. If, notwithstanding the foregoing, the
transactions contemplated hereby should be deemed a financing, the parties
intend that the Transferor shall be deemed to have granted to the Agent, on
behalf of the Investors, and the Transferor hereby grants to the Agent, on
behalf of the Investors, a first priority perfected and continuing security
interest in all of the Transferor's right, title and interest in, to and under
the Receivables, together with Related Security, Collections and Proceeds with
