          SECTION II.2.  Transfers; Certificates; Eligible Receivables.
                         --------------------------------------------- 

                 (a) Incremental Transfers. Prior to the Termination Date, upon
                     ---------------------     
the terms and subject to the conditions set forth herein and in the other
Transaction Documents, (x) the Transferor may, at its option from time to time,

such conveyance, transfer and assignment from the Transferor, without recourse
except as provided herein, undivided percentage ownership interests in the
Receivables, together with Related Security, Collections and Proceeds with
respect thereto (each, an "Incremental Transfer") from time to time prior to the
                           -------------------- 
Termination Date; provided that after giving effect to the issuance of
Commercial Paper (or, following the occurrence of a PARCO Wind-Down Event, the
obtaining of funds by the APA Banks) to fund the cash portion of the Transfer
Price of any Incremental Transfer and the payment to the Transferor of the cash
portion of such Transfer Price, the Net Investment shall not exceed the Facility
Limit; and, provided further, that the representations and warranties set forth
            -------- -------
in Section 3.1 shall be true and correct both 

                                       2
<PAGE>
 
immediately before and immediately after giving effect to any such Incremental
Transfer and the payment to the Transferor of the cash portion of the Transfer
Price related thereto.

          The Transferor shall, by notice to the Funding Agent given by
telecopy, offer to convey, transfer and assign to PARCO (prior to the occurrence
of a PARCO Wind-Down Event) or the APA Banks (following the occurrence of a
PARCO Wind-Down Event and subject to Section 2.2 of the Asset Purchase
Agreement) undivided percentage ownership interests in the Receivables and
Related Security, Collections and Proceeds with respect thereto at least three
(3) Business Days prior to the proposed date of any Incremental Transfer.  Each
such notice shall specify (x) the desired Transfer Price (which shall be at
least $1,000,000 or integral multiples of $100,000 in excess thereof) or, to the
extent that the then available unused portion of the Facility Limit is less than
such amount, such lesser amount equal to such available portion of the Facility
Limit; (y) the desired date of such Incremental Transfer; and (z) the desired
Tranche Period(s) and allocations of the Net Investment of such Incremental
Transfer thereto as required by Section 2.3.  Each Incremental Transfer shall be
subject to the condition precedent that the Collection Agent shall have
delivered to the Funding Agent, as and when due in accordance with this
Agreement, a completed Weekly Report prior to the desired date of such
Incremental Transfer, together with such other additional information as the
Funding Agent may reasonably request.  The Funding Agent will promptly notify
PARCO and the APA Banks, as applicable, of the Funding Agent's receipt of any
request for an Incremental Transfer to be made to such Person.  At its option,
PARCO shall accept or reject any such offer by notice given to the Transferor
and the Funding Agent by telephone or telecopy.

          Each notice of proposed Transfer shall be irrevocable and binding on
the Transferor, and the Transferor shall indemnify PARCO and the APA Banks
against any loss or expense incurred by PARCO and the APA Banks, either directly
or indirectly, as a result of any failure by the Transferor to complete such
Incremental Transfer, including, without limitation, any loss (including loss of
anticipated profits) or expense incurred by PARCO and the APA Banks, either
directly or indirectly, by reason of the liquidation or reemployment of funds
acquired by PARCO or the APA Banks (including, without limitation, funds
obtained by issuing Commercial Paper or promissory notes, obtaining deposits as
loans from third parties and reemployment of funds) for PARCO or the APA Banks,
as applicable to fund such Incremental Transfer.

          On the date of the initial Incremental Transfer, the Funding Agent, on
behalf of PARCO and the APA Banks, shall deliver written confirmation to the

                                       3
<PAGE>
 
Transferor of the cash portion of the Transfer Price, the Tranche Period(s) and
the Tranche Rate(s) relating to such Transfer, and the Transferor shall deliver
to the Funding Agent the Transfer Certificate in the form of Exhibit F hereto
(the "Transfer Certificate").  The Funding Agent shall indicate the amount of
      --------------------                                                   
the initial Incremental Transfer together with the date thereof on the grid
attached to the Transfer Certificate.  On the date of each subsequent
Incremental Transfer, the Funding Agent shall send written confirmation to the
Transferor of the cash portion of the Transfer Price, the Tranche Period(s), the
Transfer Date and the Tranche Rate(s) applicable to such Incremental Transfer.
The Funding Agent shall indicate the amount of the Incremental Transfer together
with the date thereof as well as any decrease in the Net Investment on the grid
attached to the Transfer Certificate.  The Transfer Certificate shall evidence
the Incremental Transfers.  Following each Incremental Transfer, the Funding
Agent, on behalf of PARCO and the APA Banks, shall deposit to the Transferor's
account at the location indicated in Section 9.3 hereof, in immediately
available funds, an amount equal to the cash portion of the Transfer Price for
such Incremental Transfer made to PARCO or the APA Banks, as applicable.

          (b) Reinvestment Transfers.  On each Business Day occurring after the
              ----------------------                                           
initial Incremental Transfer hereunder and prior to a PARCO Wind-Down Event (in
the case of PARCO) and the Termination Date (in the case of the APA Banks), the
Transferor hereby agrees to convey, transfer and assign to PARCO (prior to the
occurrence of a PARCO Wind-Down Event) and the APA Banks (following the
occurrence of a PARCO Wind-Down Event and subject to Section 2.2 of the Asset
Purchase Agreement), and in consideration of the 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, PARCO may agree to purchase (or,
following a PARCO Wind-Down Event and subject to Section 2.2 of the Asset
Purchase Agreement, the APA Banks shall 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 cash portion of 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.

                                       4
<PAGE>
 
          (c) All Transfers.  Each Transfer shall constitute a purchase 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.  PARCO's (and, following the occurrence of
a PARCO Wind-Down Event, the APA Banks') aggregate undivided percentage
ownership interest in the Receivables, together with the Related Security,
Collections and Proceeds with respect thereto, shall equal the Percentage Factor
in effect from time to time.

          (d) Percentage Factor.  The Percentage Factor shall be initially
              -----------------                                           
computed as of the opening of business of the Collection Agent on the date of
the initial Incremental Transfer hereunder.  Thereafter, until the Termination
Date, the Percentage Factor shall be automatically recomputed as of the close of
business of the Collection Agent on each day (other than a day after the
Termination Date).  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.  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, Servicing Fees and all other Aggregate
Unpaids have been paid in full, the Percentage Factor shall be fixed and shall
remain at 100%.  Following any assignment of any portion of the Transferred
Interest to the APA Banks pursuant to the Asset Purchase Agreement, the Funding
Agent shall, at all times and from time to time, calculate PARCO's and each APA
Bank's pro rata interest in the Percentage Factor and regularly report thereon
       --- ----                                                               
to PARCO and the APA Banks (with copies thereof to the Transferor).

        SECTION II.3.  Selection of Tranche Periods and Tranche Rates.
                       ---------------------------------------------- 

          (a) Transferred Interest Held by PARCO Prior to PARCO Wind-Down Event.
              -----------------------------------------------------------------
At all times hereafter, but prior to the Termination Date and not with respect
to any portion of the Transferred Interest held by any of the APA Banks, the
Transferor may, subject to PARCO's approval and the limitations described below,
request Tranche Periods and allocate a portion of the Net Investment to each
selected Tranche Period, so that the aggregate amounts allocated to outstanding
Tranche Periods at all times shall equal the portion of the Net Investment held
by PARCO.  The Transferor shall give the Funding Agent irrevocable notice by
telephone of the new requested Tranche Period(s) at least three (3) Business
Days prior to the expiration of any then existing Tranche Period; provided,
                                                                  -------- 
however, that 
-------                                                                     

                                       5

PARCO may select, in its sole discretion, any such new Tranche Period if (i) the
Transferor fails to provide such notice on a timely basis or (ii) the Funding
Agent, on behalf of PARCO, determines, in its sole discretion, that the Tranche
Period requested by the Transferor is unavailable or for any reason commercially
undesirable. PARCO confirms that it is its intention to allocate all or
substantially all of the portion of the Net Investment held by it to one or more
CP Tranche Periods; provided that PARCO may determine, from time to time, in its
                    --------
sole discretion, that funding such portion of the Net Investment by means of one
or more CP Tranche Periods is not possible or is not desirable for any reason.

          (b) Transferred Interest Held by PARCO Following the Termination Date.
              ----------------------------------------------------------------- 
At all times on and after the Termination Date, with respect to any portion of
the Transferred Interest which shall not have been transferred to the APA Banks
(or any of them), PARCO or the Funding Agent, as applicable, shall select all
Tranche Periods and Tranche Rates applicable thereto.

          (c) Transferred Interest Held by the APA Banks Prior to the
              -------------------------------------------------------
Termination Date.  At all times with respect to any portion of the Transferred
----------------                                                              
Interest transferred to the APA Banks (or any of them) pursuant to the Asset
Purchase Agreement, 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 three (3) days, and such Tranche shall be a BR
Tranche.  Thereafter (but prior to the Termination Date or the occurrence and
continuation of a Potential Termination Event), with respect to such portion,
and with respect to any other portion of the Transferred Interest held by the
APA Banks (or any of them), 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 Funding Agent irrevocable notice by telephone of the
new requested Tranche Period at least three (3) Business Days prior to the
expiration of any then existing Tranche Period.  Any Tranche Period maintained
by the APA Banks which is outstanding on the Termination Date shall end on the
Termination Date.

          (d) After the Termination Date; Transferred Interest Held by APA
              ------------------------------------------------------------

portion of the Transferred Interest which shall have been owned by, or
transferred to, the APA Banks (or any of them), the Funding Agent shall select
all Tranche Periods and Tranche Rates applicable thereto.

        SECTION II.4.  Discount, Fees and Other Costs and Expenses.
                       -------------------------------------------  
Notwithstanding the limitation on recourse under Section 2.1 hereof, the
Transferor 

                                       6
<PAGE>
 
shall pay, as and when due in accordance with this Agreement and the
other Transaction Documents, all fees hereunder, Discount, Servicing Fees and
other Aggregate Unpaids that are properly due and payable by it.  On the last
day of each Tranche Period, the Transferor shall pay to the Funding Agent, on
behalf of PARCO and/or the APA Banks, as applicable, an amount equal to the
accrued and unpaid Discount for such Tranche Period together with, in the event
any portion of the Transferred Interest is held by PARCO, an amount equal to the
discount accrued on PARCO's Commercial Paper to the extent such Commercial Paper
was issued in order to fund the Transferred Interest in an amount in excess of
the cash portion of the Transfer Price of an Incremental Transfer; provided that
                                                                   --------     
(i) in the event of any repayment or prepayment of a BR Tranche or a Eurodollar
Tranche, accrued Discount on the principal amount repaid or prepaid shall be
payable on the date of such repayment or prepayment and (ii) in the event of any
conversion of a BR Tranche or a Eurodollar Tranche, accrued interest on such BR
Tranche or Eurodollar Tranche shall be payable on the effective date of such
conversion.  Discount shall accrue with respect to each Tranche on each day
occurring during the Tranche Period related thereto.

          Nothing in this Agreement or the other Transaction Documents shall
limit in any way the obligations of the Transferor to pay the amounts set forth
in this Section 2.4.

          SECTION II.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 PARCO or the APA
Banks, as applicable (or deposit into the Collection Account if so required
pursuant to Section 2.12 hereof) an amount equal to all Discount and the
Servicing Fee accrued through such day and not so previously set aside or paid
and (ii) apply the balance of such Percentage Factor of Collections remaining
after application of Collections as provided in clause (i) of this Section 2.5
hereof to the Transferor, for the benefit of PARCO and/or the APA Banks, as
applicable, to the purchase of additional undivided percentage interests in each
Receivable pursuant to Section 2.2(b) hereof.  On the last day of each Tranche
Period, from the amounts set aside as described in clause (i) of the first
sentence of this Section 2.5 hereof, the Collection Agent shall deposit to the
Funding Account, for the benefit of PARCO and/or the APA Banks, as applicable,
an amount equal to the accrued and unpaid Discount for such Tranche Period and
shall deposit to its own account an amount equal to the accrued and unpaid
Servicing Fee for such Tranche Period.  The Funding Agent, upon its receipt of
such amounts in the 

                                       7
<PAGE>
 
Funding Account, shall distribute such amounts to PARCO and/or the APA Banks
entitled thereto as set forth above; provided that if the Funding Agent shall
                                     -------- 
have insufficient funds to pay all of the above amounts in full on any such
date, the Funding Agent shall notify the Transferor and the Transferor shall
immediately pay to the Funding Agent, from funds previously paid to the
Transferor, an amount equal to such insufficiency. In addition, the Collection
Agent shall remit to the Transferor, at the end of each Tranche Period, such
portion of Collections not allocated to PARCO and the APA Banks.

          SECTION II.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
Funding Agent, for the benefit of PARCO and/or the APA Banks, as applicable,
from previously received Collections, an amount equal to the amount such that,
when applied in reduction of the Net Investment, will result in a Percentage
Factor less than or equal to the Maximum Percentage Factor.  Such amount shall
be applied to the reduction of the Net Investment of Tranche Periods selected by
the Funding Agent.  On the Termination Date and on each day thereafter, and on
each day on which a Potential Termination Event has occurred and is continuing,
the Collection Agent shall set aside and hold in trust for PARCO and/or the APA
Banks, as applicable (or deposit into the Collection Account if so required
pursuant to Section 2.12 hereof), the Percentage Factor of all Collections
received on such day and shall set aside and hold in trust for the Transferor
such portion of Collections not allocated to PARCO and/or the APA Banks, as
applicable.  On the Termination Date or the day on which a Potential Termination
Event occurs, the Collection Agent shall deposit to the Funding Account, for the
benefit of PARCO or the APA Banks, as applicable, any amounts set aside pursuant
to Section 2.5 above.

          On the last day of each Tranche Period to occur on or after the
Termination Date or during the continuation of a Potential Termination Event,
the Collection Agent shall deposit to the Funding Account, for the benefit of
PARCO and the APA Banks, as applicable, the amounts so set aside for PARCO and
the APA Banks pursuant to the second preceding sentence, but not to exceed the
sum of (i) the accrued Discount for such Tranche Period, (ii) the portion of the
Net Investment allocated to such Tranche Period, and (iii) all other Aggregate
Unpaids.  On such day, the Collection Agent shall deposit to its account, from
the amounts set aside for PARCO and the APA Banks pursuant to the preceding
sentence which remain after payment in full of the aforementioned amounts, the
accrued Servicing Fee for such Tranche Period.  If there shall be insufficient
funds on deposit for the Collection Agent to distribute funds in payment in full
of the aforementioned amounts, the 

                                       8
<PAGE>
 
Collection Agent shall distribute funds first, in payment of the accrued
                                        -----
Discount, second, if the Transferor, the Originator or any Affiliate of the
          ------
Transferor or the Originator is not then the Collection Agent, to the Collection
Agent's account, in payment of the Servicing Fee payable to the Collection
Agent, third, in reduction of the Net Investment allocated to any Tranche Period
       -----
ending on such date, fourth, in payment of all fees payable by the Transferor
                     ------
hereunder, fifth, in payment of all other Aggregate Unpaids and sixth, if the
           -----                                                -----
Transferor, the Originator or any Affiliate of the Transferor or the Originator
is the Collection Agent, to its account as Collection Agent, in payment of the
Servicing Fee payable to such Person as Collection Agent. The Funding Agent,
upon its receipt of such amounts in the Funding Agent's account, shall
distribute such amounts to PARCO and/or the APA Banks entitled thereto as set
forth above; provided that if the Funding Agent shall have insufficient funds to
             --------
pay all of the above amounts in full on any such date, the Funding Agent shall
pay such amounts in the order of priority set forth above and, with respect to
any such category above for which the Funding Agent shall have insufficient
funds to pay all amounts owing on such date, ratably (based on the amounts in
such categories owing to such Persons) among all such Persons entitled to
payment thereof.

          Following the date on which the Net Investment has been reduced to
zero and all accrued Discount, Servicing Fees and all other Aggregate Unpaids
have been paid in full, (i) the Collection Agent shall recompute the Percentage
Factor, (ii) the Funding Agent, on behalf of PARCO and the APA Banks, shall be
deemed to have reconveyed to the Transferor all of PARCO's and the APA Banks'
right, title and interest in, to and under the Receivables and Related Security,
Collections and Proceeds with respect thereto, (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
Funding Agent, on behalf of PARCO and the APA Banks, shall execute and deliver
to the Transferor, at the Transferor's expense, such documents or instruments as
are necessary to terminate PARCO's and the APA Banks' respective interests in
the Receivables and Related Security, Collections and Proceeds with respect
thereto.  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 II.7.  Fees.  Notwithstanding any limitation on recourse
                         ----                                             
contained in this Agreement, the Transferor shall pay, as and when due in
accordance with the Fee Letter, the fees specified in the Fee Letter.

          SECTION II.8.  Protection of Ownership Interest of PARCO and the APA
                         -----------------------------------------------------
Banks.
----- 

          (a) Each of the Transferor and the Originator agrees that it will,
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 Funding Agent
may reasonably request in order to perfect or protect the Transferred Interest
or to enable the Funding Agent, PARCO or the APA Banks to exercise or enforce
any of their respective  rights hereunder.  Without limiting the foregoing, each
of the Transferor and the Originator will, upon the request of the Funding
Agent, PARCO or any of the APA Banks, in order to accurately reflect this
purchase and sale transaction, (x) execute and file such financing or
continuation statements or amendments thereto or assignments thereof (as
permitted pursuant to Section 10.6 hereof) as may be requested by the Funding
Agent for the benefit of PARCO and the APA Banks and (y) mark its respective
master data processing records and other documents with a legend describing the
conveyance of Receivables to the Transferor (in the case of the Originator) and
the conveyance of the Transferred Interest to the Funding Agent for the benefit
of PARCO and the APA Banks.  Each of the Transferor and the Originator shall,
upon request of the Funding Agent, obtain such additional search reports as the
Funding Agent, for the benefit of PARCO and the APA Banks, shall request.  To
the fullest extent permitted by applicable law, the Funding Agent shall be
permitted to sign and file continuation statements and amendments thereto and
assignments thereof without the Transferor's or the Originator's signature.
Carbon, photographic or other reproduction of this Agreement or any financing
statement shall be sufficient as a financing statement.  Neither the Transferor
nor the Originator shall change its name, identity or corporate structure
(within the meaning of Section 9-402(7) of the Relevant UCC), nor relocate its
respective chief executive office or any office where Records are kept unless it
shall have:  (i) given the Funding Agent at least ten (10) days' prior notice
thereof and (ii) prepared at Transferor's expense and delivered to the Funding
Agent all financing statements, instruments and other documents necessary to
preserve and protect the Transferred Interest or requested by the Funding Agent
in connection with such change or relocation.  Any filings under the Relevant
UCC or otherwise that are occasioned by such change in name or location shall be
made at the expense of Transferor.

          (b) The Collection Agent shall instruct all Obligors to cause all
Collections to be deposited directly into a Lock-Box Account.  Any Lock-Box
Account maintained by a Lock-Box Bank pursuant to the related Lock-Box Agreement
shall be under the exclusive ownership and control of the Funding Agent which is
hereby granted to the Funding Agent by the Transferor (as assignee of the

                                       10
<PAGE>
 
Originator).  The Collection Agent shall be permitted to give instructions to
the Lock-Box Banks for so long as neither a Collection Agent Default nor any
other Termination Event or Potential Termination Event has occurred and is
continuing hereunder.  The Collection Agent shall not add any bank as a Lock-Box
Bank to those listed on Exhibit C attached hereto unless such bank has entered
into a Lock-Box Agreement.  The Collection Agent shall not terminate any bank as
a Lock-Box Bank unless the Administrative Agent shall have received fifteen (15)
days' prior notice of such termination.  If the Transferor, the Originator or
the Collection Agent receives any Collections, then the Transferor, the
Originator or the Collection Agent, as applicable, shall immediately, but in no
event later than one (1) Business Day after receipt thereof, remit such
Collections to a Lock-Box Account.

          SECTION II.9.  Deemed Collections; Application of Payments.  (a)  If
                         -------------------------------------------          
on any day a Receivable becomes a Diluted Receivable, 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.  Any 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 actually received by the Funding Agent.

          (b) If, on any day, any representation or warranty made herein with
respect to any Receivable is determined to be incorrect or untrue in any
material respect as of the date such representation or warranty was made, the
Transferor shall be deemed to have received on such day a Collection of 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 actually received by the Funding Agent.  Simultaneously with any
such payment by the Transferor, each of PARCO and the APA Banks, as the case may
be, shall convey all of its right, title and interest in such Receivable and
Related Security to the Transferor, and the Funding Agent, on behalf of PARCO
and the APA Banks, shall take all action reasonably requested by the Transferor
to effectuate such conveyance.

          (c) Any payment by an Obligor in respect of a Receivable shall, except
as otherwise specified by such Obligor or otherwise required by contract or law
and unless otherwise instructed by PARCO, be applied as a Collection of any
Receivable of such Obligor included in the Transferred Interest (starting with
the 

                                       11
<PAGE>
 
oldest such Receivable) to the extent of any amounts then due and payable
thereunder before being applied to any other receivable or other indebtedness of
such Obligor.

          SECTION II.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 time) on the day when due in immediately available funds; if such
amounts are payable to PARCO (or any APA Bank), they shall be paid or deposited
in the Funding Account, until otherwise notified by the Funding Agent.  No later
than 4:30 P.M. (New York time) on the date of any Incremental Transfer
hereunder, PARCO or the APA Banks, as applicable, will make available to the
Transferor, in immediately available funds, the amount of such Incremental
Transfer on such day by remitting such amount to an account of the Transferor
specified in the related notice of Transfer.  The Transferor shall, to the
extent permitted by law, pay to the Funding Agent, for the benefit of PARCO
and/or the APA Banks upon demand, interest on all amounts 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 (or, in the case of Discount calculated
at the Base Rate, a year of 365 or 366 days, as applicable) for the actual
number of days (including the first but excluding the last day) elapsed.  Any
computations by the Funding Agent of amounts payable by the Transferor hereunder
shall be binding upon the Transferor absent manifest error.

          SECTION II.11.  Reports.  (a)  The Collection Agent shall prepare and
                          -------                                              
forward to the Funding Agent and the Transferor (i) on each Settlement Date, a
Settlement Statement as of the end of the last day of the immediately preceding
Settlement Period and (ii) on any other Business Day, such other information as
the Transferor or Funding Agent may reasonably request.

          (b)  The Collection Agent shall submit to the Funding Agent, no later
than 1:00 P.M. (New York time) on each Weekly Settlement Date (or, after the
occurrence and continuation of a Termination Event or Potential Termination
Event, on each Business Day), a written report substantially in the form
attached hereto as Exhibit B (the "Deposit Report") setting forth total
                                   --------------                      
Collections deposited in the Collection Account, Receivables and Eligible
Receivables created during the immediately preceding calendar week, and such
other information as the Funding Agent may reasonably request.  The Deposit
Report may be delivered in an electronic format mutually agreed upon by the
Collection Agent and the Funding Agent or, pending such agreement, by facsimile.
By delivery of a Deposit Report, the 

                                       12
<PAGE>
 
Originator shall be deemed to have made a representation and warranty that the
information set forth therein is true and correct in all material respects.

          SECTION II.12.  Collection Account.  There shall be established on the
                          ------------------                                    
day of the initial Incremental Transfer hereunder and maintained, for the
benefit of the Funding Agent on behalf of PARCO and the APA Banks, a segregated
account (the "Collection Account"), bearing a designation clearly indicating
              ------------------                                            
that the funds deposited therein are held for the benefit of PARCO and the APA
Banks.  On and after the occurrence of a Collection Agent Default or a
Termination Event or a Potential Termination Event, the Collection Agent shall
remit daily 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 Funding Agent in Permitted
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, all interest and earnings (net of losses and
investment expenses) on funds on deposit in the Collection Account shall be
retained in the Collection Account and be available to make any payments
required to be made hereunder (including Discount) by the Transferor.  On the
date on which the Net Investment is zero, all accrued Discount, Servicing Fees
and all other Aggregate Unpaids have been paid in full, any funds remaining on
deposit in the Collection Account shall be paid to the Transferor.

          SECTION II.13.  Right of Setoff.  Each of PARCO and the APA Banks is
                          ---------------                                     
hereby authorized (in addition to any other rights it may have) at any time
after the occurrence of the Termination Date, or during the continuation of a
Potential Termination Event, to set-off, appropriate and apply (without
presentment, demand, protest or other notice which are hereby expressly waived)
any deposits and any other indebtedness held or owing by PARCO or such APA Bank
to, or for the account of, the Transferor against the amount of the Aggregate
Unpaids owing by the Transferor to such Person (even if contingent or
unmatured).

          SECTION II.14.  Sharing of Payments, Etc.  If PARCO or any APA Bank
                          ------------------------                           
(for purposes of this Section 2.14 only, being a "Recipient") shall obtain any
                                                  ---------                   
payment (whether voluntary, involuntary, through the exercise of any right of
setoff, or otherwise) on account of any interest in the Transferred Interest
owned by it in excess of its ratable share of payments on account of any
interest in the Transferred Interest obtained by PARCO and/or the APA Banks
entitled thereto, such Recipient shall forthwith purchase from PARCO and/or the
APA Banks entitled to a share of such amount participations in the percentage
interests owned by such Persons as shall be necessary to cause such Recipient to
share the excess payment ratably with each 

                                       13
<PAGE>
 
such other Person entitled thereto; provided, however, that if all or any
                                    --------  -------
portion of such excess payment is thereafter recovered from such Recipient, such
purchase from each such other Person shall be rescinded and each such other
Person shall repay to the Recipient the purchase price paid by such Recipient
for such participation to the extent of such recovery, together with an amount
equal to such other Person's ratable share (according to the proportion of (a)
the amount of such other Person's required payment to (b) the total amount so
recovered from the Recipient) of any interest or other amount paid or payable by
the Recipient in respect of the total amount so recovered.

          SECTION II.15.  Broken Funding.  In the event of (a) the payment of
                          --------------                                     
any principal of any Eurodollar Tranche other than on the last day of the
Eurodollar Tranche Period applicable thereto (including as a result of the
occurrence of the Termination Date or an optional prepayment of a Eurodollar
Tranche), (b) the conversion of any Eurodollar Tranche other than on the last
day of the related Eurodollar Tranche Period, or (c) any failure to borrow,
convert, continue or prepay any Eurodollar Tranche on the date specified in any
notice delivered pursuant hereto, then, in any such event, the Transferor shall
compensate the APA Banks for the loss, cost and expense attributable to such
event.  Such loss, cost or expense to any APA Bank shall be deemed to include an
amount determined by such APA Bank to be the excess, if any, of (i) the amount
of Discount which would have accrued on the principal amount of such Eurodollar
Tranche had such event not occurred, at the Eurodollar Rate that would have been
applicable to such Eurodollar Tranche, for the period from the date of such
event to the last day of the Eurodollar Tranche Period (or, in the case of a
failure to borrow, convert or continue, for the period that would have been the
related Eurodollar Tranche Period), over (ii) the amount of interest which would
accrue on such principal amount for such period at the interest rate which such
APA Bank would bid were it to bid, at the commencement of such period, for
dollar deposits of a comparable amount and period from other banks in the
interbank eurodollar market.  Within forty-five (45) days after any APA Bank
hereunder receives actual knowledge of any of the events specified in this
Section 2.15, a certificate of such APA Bank setting forth any amount or amounts
that such APA Bank is entitled to receive pursuant to this Section 2.15 and the
reason(s) therefor shall be delivered to the Transferor (with a copy to the
Funding Agent) and shall be conclusive absent manifest error.  The Transferor
shall pay each such APA Bank the amount shown as due on any such certificate
within ten (10) days after receipt thereof.

option of the Transferor, be converted to a Eurodollar Tranche and (b) each
Eurodollar Tranche may, at the option of the Transferor, be continued as a
Eurodollar Tranche or converted to a BR Tranche. If the Termination Date has
occurred or a Potential Termination Event has occurred and is continuing, then
(i) no outstanding Tranche funded by the APA Banks may be converted to, or
continued as, a Eurodollar Tranche and (ii) unless repaid, each Eurodollar
Tranche shall be converted to an BR Tranche on the last day of the Tranche
Period related thereto. For any such conversion or continuation, the Transferor
shall give the Funding Agent irrevocable notice (each, a "Conversion/
                                                          -----------
Continuation Notice") of such request not later than 12:30 P.M. (New York time)
-------------------
(i) in the case of a conversion of a BR Tranche into a Eurodollar Tranche, or a
continuation of a Eurodollar Tranche as a Eurodollar Tranche, three (3) Business
Days before the date of such conversion or continuation, as applicable, and (ii)
following the Termination Date or the occurrence and continuation of a Potential
Termination Event, in the case of a conversion of a Eurodollar Tranche into a BR
Tranche or a continuation of a BR Tranche as a BR Tranche, on the Business Day
of such conversion. If a Conversion/Continuation Notice has not been timely
delivered with respect to any BR Tranche or Eurodollar Tranche, such Tranche
shall be automatically continued as, or converted to, a BR Tranche. Each
Conversion/Continuation Notice shall specify (a) the requested date (which shall
be a Business Day) of such conversion or continuation, (b) the aggregate amount
and rate option applicable to the Tranche which is to be converted or continued
and (c) the amount and rate option(s) of Tranche(s) into which such Tranche is
to be converted or continued.

          SECTION II.17.  Illegality.  (a)  Notwithstanding any other provision
                          ----------                                           
herein, if, after the Effective Date, the adoption of any Law or bank regulatory
guideline or any amendment or change in the interpretation of any existing or
future Law or bank regulatory guideline by any Official Body charged with the
administration, interpretation or application thereof, or the compliance with
any directive of any Official Body (in the case of any bank regulatory
guideline, whether or not having the force of Law), shall make it unlawful for
any APA Bank to acquire or maintain a Eurodollar Tranche as contemplated by this
Agreement, (i) such APA Bank shall, within thirty (30) days after receiving
actual knowledge thereof, deliver a certificate to the Transferor (with a copy
to the Funding Agent) setting forth the basis for such illegality, which
certificate shall be conclusive absent manifest error, (ii) the commitment of
such APA Bank hereunder to make a portion of a Eurodollar Tranche, continue any
portion of a Eurodollar Tranche as such and convert a BR Tranche to a Eurodollar
Tranche shall forthwith be cancelled, and such cancellation shall remain in
effect so long as the circumstance described above exists, and (iii) such APA

                                       15
<PAGE>
 
Bank's portion of any Eurodollar Tranche then outstanding shall be converted
automatically to a BR Tranche on the last day of the related Eurodollar Tranche
Period, or within such earlier period as required by law.

          If any such conversion of a portion of a Eurodollar Tranche occurs on
a day which is not the last day of the related Eurodollar Tranche Period, the
Transferor shall pay to such APA Bank such amounts, if any, as may be required
to compensate such APA Bank.  If circumstances subsequently change so that it is
no longer unlawful for an affected APA Bank to acquire or to maintain a portion
of a Eurodollar Tranche as contemplated hereunder, such APA Bank will, as soon
as reasonably practicable after such APA Bank knows of such change in
circumstances, notify the Transferor and the Funding Agent, and upon receipt of
such notice, the obligations of such APA Bank to acquire or maintain its
acquisition of portions of Eurodollar Tranches or to convert its portion of a BR
Tranche into portions of Eurodollar Tranches shall be reinstated.

          (b) Each APA Bank agrees that, upon the occurrence of any event giving
rise to the operation of Section 2.17(a) with respect to such APA Bank, it will,
if requested by the Transferor and to the extent permitted by law or by the
relevant Official Body, endeavor in good faith to change the office at which it
books its portions of Eurodollar Tranches hereunder if such change would make it
lawful for such APA Bank to continue to acquire or to maintain its acquisition
of portions of Eurodollar Tranches hereunder; provided, however, that such
                                              --------  -------           
change may be made in such manner that such APA Bank, in its sole determination,
suffers no unreimbursed cost or expense or any other disadvantage whatsoever.

          SECTION II.18.  Inability to Determine Eurodollar Rate.  If, prior to
                          --------------------------------------               
the first day of any Eurodollar Tranche Period:

          (1) the Funding Agent shall have determined (which determination in
     the absence of manifest error shall be conclusive and binding upon the
     Transferor) that, by reason of circumstances affecting the relevant market,
     adequate and reasonable means do not exist for ascertaining the Eurodollar
     Rate for such Eurodollar Tranche Period; or

          (2) the Funding Agent shall have received notice from the Required APA
     Banks that the Eurodollar Rate determined or to be determined for such
     Eurodollar Tranche Period will not adequately and fairly reflect the cost
     to such APA Banks (as conclusively certified by such APA Banks) of

                                       16
<PAGE>
 
     purchasing or maintaining their affected portions of Eurodollar Tranches
     during such Eurodollar Tranche Period;

then, in either such event, the Funding Agent shall give telecopy or telephonic
notice thereof (confirmed in writing) to the Transferor and the APA Banks as
soon as practicable (but, in any event, within thirty (30) days after such
determination or notice, as applicable) thereafter.  Until such notice has been
withdrawn by the Funding Agent, no further Eurodollar Tranches shall be made.
The Funding Agent agrees to withdraw any such notice as soon as reasonably
practicable after the Funding Agent is notified of a change in circumstances
which makes such notice inapplicable.

that computer applications used by Transferor may be unable to recognize and
perform properly date-sensitive functions involving certain dates prior to and

failure to do so is not reasonably likely to result in a Material Adverse

                        ADMINISTRATION AND COLLECTIONS

          SECTION VI.1.  Appointment of Collection Agent.  The servicing,
                         -------------------------------

Termination Event, designate as Collection Agent any Person (including itself)
to succeed the Originator or any successor Collection Agent, on the condition in
each case that any such Person so designated shall agree to perform the duties
and obligations of the Collection Agent pursuant to the terms hereof.  Following
a Collection Agent Default or a Termination Event, the Funding Agent may notify
any Obligor of the Transferred Interest of the designation of a successor
Collection Agent. The Collection Agent may not delegate any of its rights,
duties or obligations hereunder, or designate a substitute Collection Agent,

Originator shall be permitted to delegate its duties hereunder to any of its
Affiliates or their agents, but such delegation shall not relieve the Originator

          SECTION VI.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, with
reasonable care and diligence, and in accordance with the Credit and Collection
Policy.  Each of the Transferor, PARCO and the Funding Agent, for the benefit of
the APA Banks, 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 Receivables and Related Security, Collections and
Proceeds with respect thereto.  To the extent permitted by applicable law, each
of the Transferor and the Originator (to the extent not then acting as
Collection Agent hereunder) hereby grants to any Collection Agent appointed
hereunder an irrevocable power of attorney to take in the Transferor's and/or
the Originator's name and on behalf of the Transferor or the Originator any and
all steps necessary or desirable, in the reasonable 

                                       36
<PAGE>
 
determination of the Collection Agent, to collect all amounts due under any and
all Receivables, including, without limitation, endorsing the Transferor's
and/or the Originator's name on checks and other instruments representing
Collections and enforcing such Receivables and the related Contracts. The
Collection Agent shall set aside for the account of the Transferor and PARCO
their respective allocable shares of the Collections of Receivables in
accordance with Sections 2.5 and 2.6 hereof. The Collection Agent shall
segregate and deposit to the Funding Agent's account PARCO's allocable share of
Collections of Receivables when required pursuant to Article II hereof. The
Transferor shall deliver to the Collection Agent and the Collection Agent shall
hold in trust for the Transferor, PARCO, the Funding Agent and the APA Banks, in
accordance with their respective interests, all Records which evidence or relate
to Receivables, Related Security or Collections. Notwithstanding anything to the
contrary contained herein, following a Termination Event or Potential
Termination Event, the Funding Agent shall have the absolute and unlimited right
to direct the Collection Agent (whether the Collection Agent is the Originator
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 Funding Agent, PARCO or any of
the APA Banks 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 Originator any collections of any indebtedness
of any Person which is not on account of a Receivable.  If the Collection Agent
is not the Transferor, the Originator or an Affiliate of the Transferor or the
Originator, the Collection Agent, by giving three (3) Business Days' prior
written notice to the Funding Agent, may revise the Servicing Fee, provided that
                                                                   --------     
such revised Servicing Fee payable to such successor Collection Agent shall be a
fee agreed upon by the Collection Agent and the Funding Agent on an arms-length
basis reflecting rates and terms prevailing at such time (it being understood
that the Servicing Fee represents an arms-length arrangement as of the date of
this Agreement).  The Collection Agent, if other than the Originator or an
Affiliate of the Originator, shall as soon as practicable upon demand, deliver
to the Originator all Records in its possession which evidence or relate to
indebtedness of an Obligor which is not a Receivable.

          (c)  On or before ninety (90) days after the end of each fiscal year
of the Collection Agent, beginning with the fiscal year ending December 31,
1998, the Collection Agent shall cause a firm of independent public accountants
acceptable to the Funding Agent at the expense of the Transferor (who may also
render other services to the Collection Agent, the Transferor, the Originator or
any Affiliates of any of the foregoing) to furnish a report to the Funding Agent
to the 

                                       37

effect that they have (i) selected at least one Settlement Statement for
each fiscal quarter delivered during the fiscal year then ended and verified
that the amounts presented on such Settlement Statement relating to sales, total
dilution, net sales, collections, write-offs and aging of Receivables agreed
with the information contained within the Collection Agent's underlying
accounting records for such Settlement Period, (ii) recalculated the Net
Receivables Balance as of the end of at least one Settlement Period of each
fiscal quarter,  (iii) verified that the Receivables treated by the Collection
Agent as Eligible Receivables in fact satisfied the requirements of clauses
(iii),  (iv) and (viii) of the definition of such term contained herein, (iv)
selected at least one Settlement Statement for each fiscal quarter and conducted
a "negative confirmation" of a sample of fifty (50) Receivables (or such other
sample consented to by the Funding Agent, which consent shall not be
unreasonably withheld) and verified that the Collection Agent's records and
computer system used in servicing the Receivables contained correct information
with regard to outstanding balances, and (v) selected at least one Settlement
Statement for each fiscal quarter and selected a sample of fifty (50)
Receivables (or such other sample consented to by the Funding Agent, which
consent shall not be unreasonably withheld) (which can be the same sample
selected in clause (iv) above) and verified that such Receivables were included
in the proper aging category on such Settlement Statement based on the dates
listed on the original Contracts for such Receivables, except, in each case for
(a) such exceptions as such firm 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 shall have no obligation to collect, enforce or
take any other action described in this Article VI with respect to any
indebtedness which is not on account of a Receivable other than to deliver to
the Originator the collections and documents with respect to any such
indebtedness as described in Section 6.2(b) hereof.

          SECTION VI.3.  Rights After Designation of New Collection Agent.  At
                         ------------------------------------------------     
any time following the designation of a Collection Agent pursuant to Section 6.1
hereof:

               (i)  The Funding Agent may, at its option, or shall, at the

     payments be made directly to the Funding Agent or its designee.

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

               (iv)  The Transferor and the Originator hereby authorize the
     Funding Agent to take any and all steps in the Transferor's or the
     Originator's name and on behalf of the Transferor and the Originator
     necessary or desirable, in the determination of the Funding Agent, to
     collect all amounts due under any and all Receivables, including, without
     limitation, endorsing the Transferor's or the Originator's name on checks
     and other instruments representing Collections and enforcing such
     Receivables and the related Contracts.

Indemnified Party to compensation pursuant to this Article VIII, notify the
Transferor in writing.  Any notice by the Funding Agent claiming compensation
under this Article VIII and setting forth the additional amount or amounts to be
paid to it hereunder shall be conclusive in the absence of manifest error.  In
determining such amount, the Funding Agent or any applicable Indemnified Party
may use any reasonable averaging and attributing methods.

          SECTION IX.4.  Governing Law; Submission to Jurisdiction; Integration.
                         ------------------------------------------------------ 

          (a  This Agreement shall be governed by, and construed in accordance
with the laws of the State of New York.  Each of the parties hereto hereby
submits to the nonexclusive jurisdiction of the United States District Court for
the Southern District of New York and of any New York state court sitting in The
City of New York for purposes of all legal proceedings arising out of or
relating to this Agreement or the transactions contemplated hereby.  Each of the
parties hereto 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 9.4 shall affect the right of the
Funding Agent, PARCO or the APA Banks to bring any action or proceeding against
the Transferor, the Originator, or their respective properties in the courts of
other jurisdictions.

          (b  Each of the parties hereto hereby waives any right to have a jury
participate in resolving any dispute, whether sounding in contract, tort or
otherwise among any of them arising out of, connected with, relating to or
incidental to the relationship between them in connection with this Agreement or
the other Transaction Documents.

          (c  This Agreement contains the final and complete integration of all
prior expressions by the parties hereto with respect to the subject matter
hereof and shall constitute the entire Agreement among the parties hereto with

                                       55
<PAGE>
 
respect to the subject matter hereof superseding all prior oral or written
understandings.

          SECTION IX.5.  Severability; Counterparts.  This Agreement may be
                         --------------------------                        
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which when taken together shall constitute one and the same
Agreement.  Any provisions of this Agreement which are prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

          SECTION IX.6.  Successors and Assigns.  This Agreement shall be
                         ----------------------                          
binding on the parties hereto and their respective successors and assigns;
provided, however, that, except as specifically provided herein or in the other
--------  -------                                                              
Transaction documents, neither the Transferor, nor the Originator may assign any
of its rights or delegate any of its duties hereunder or under any of the other
Transaction Documents to which it is a party without the prior written consent
of the Funding Agent.  No provision of this Agreement shall in any manner
restrict the ability of PARCO or any APA Bank to assign, participate, grant
security interests in, or otherwise transfer any portion of the Transferred
Interest.  Without limiting the foregoing, PARCO may (with the consent of each
APA Bank), in one or a series of transactions, transfer all or any portion of
the Transferred Interest held by it, and its rights and obligations under this
Agreement and the other Transaction Documents to which it is a party, to a
Conduit Assignee.

          SECTION IX.7.  Confidentiality.  (a)  Each of the Transferor and the
                         ---------------                                      
Originator shall maintain, and shall cause each officer, employee and agent of

Documents and all other confidential proprietary information with respect to
PARCO, the Funding Agent and the APA Banks and each of their respective
businesses obtained by them in connection with the structuring, negotiation and
execution of the transactions contemplated herein and in the other Transaction
Documents, except for information that has become publicly available or
information disclosed (i) to legal counsel, accountants and other professional
advisors to the Transferor, the Originator and their Affiliates, (ii) as
required by law, regulation or legal process or (iii) in connection with any
legal or regulatory proceeding to which the Transferor, the Originator or any of
their Affiliates is subject.  Each of the Transferor and the Originator hereby
consents to the disclosure of any non-public information with respect to it
received 

                                       56

Agent, any APA Bank, (ii) any nationally recognized rating agency providing a
rating or proposing to provide a rating to PARCO's Commercial Paper, (iii) any
placement agent which proposes to offer and sell PARCO's Commercial Paper, (iv)
any provider of PARCO's program-wide liquidity or credit support facilities, (v)
any potential APA Bank or (vi) any Participant or potential Participant.

          (b  Each of PARCO, the Funding Agent and the APA Banks shall
maintain, and shall cause each officer, employee and agent of itself and its
Affiliates to maintain, the confidentiality of the Transaction Documents and all
other confidential proprietary information with respect to the Transferor, the
Originator and their Affiliates and each of their respective businesses obtained
by them in connection with the structuring, negotiation and execution of the
transactions contemplated herein and in the other Transaction Documents, except
for information that has become publicly available or information disclosed (i)
to legal counsel, accountants and other professional advisors to PARCO, the
Funding Agent and the APA Banks, (ii) as required by law, regulation or legal
process or (iii) in connection with any legal or regulatory proceeding to which
PARCO, the Funding Agent and the APA Banks is subject.

          SECTION IX.8.  No Bankruptcy Petition Against PARCO.  Each of the
                         ------------------------------------              
Transferor and the Originator hereby covenants and agrees that, prior to the
date which is one year and one day after the payment in full of all outstanding
Commercial Paper or other indebtedness of PARCO, it will not institute against,
or join any other Person in instituting against, PARCO any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings or other
similar proceeding under the laws of the United States or any state of the
United States.

          SECTION IX.9.  Limited Recourse.  Notwithstanding anything to the
                         ----------------                                  
contrary contained herein, the obligations of PARCO under this Agreement are
solely the corporate obligations of PARCO and, in the case of obligations of
PARCO other than Commercial Paper, shall be payable at such time as funds are
actually received by, or are available to, PARCO in excess of funds necessary to
pay in full all outstanding Commercial Paper and, to the extent funds are not
available to pay such obligations, the claims relating thereto shall not
constitute a claim against PARCO but shall continue to accrue.  Each party
hereto agrees that the payment of any claim (as defined in Section 101 of the
Bankruptcy Code) of any such party shall be subordinated to the payment in full
of all Commercial Paper.

                                       57
<PAGE>
 
          No recourse under any obligation, covenant or agreement of PARCO
contained in this Agreement shall be had against any incorporator, stockholder,
officer, director, member, manager, employee or agent of PARCO, the
Administrative Agent, the Manager or any of their Affiliates (solely by virtue
of such capacity) by the enforcement of any assessment or by any legal or
equitable proceeding, by virtue of any statute or otherwise; it being expressly
agreed and understood that this Agreement is solely a corporate obligation of
PARCO, and that no personal liability whatever shall attach to or be incurred by
any incorporator, stockholder, officer, director, member, manager, employee or
agent of PARCO, the Administrative Agent, the Manager or any of their Affiliates
(solely by virtue of such capacity) or any of them under or by reason of any of
the obligations, covenants or agreements of PARCO contained in this Agreement,
or implied therefrom, and that any and all personal liability for breaches by
PARCO of any of such obligations, covenants or agreements, either at common law
or at equity, or by statute, rule or regulation, of every such incorporator,
stockholder, officer, director, member, manager, employee or agent is hereby
expressly waived as a condition of and in consideration for the execution of
this Agreement; provided that the foregoing shall not relieve any such Person
                --------                                                     
from any liability it might otherwise have as a result of fraudulent actions
taken or fraudulent omissions made by them.

          SECTION IX.10.  Characterization of the Transactions Contemplated by
                          ----------------------------------------------------
the Agreement.  It is the intention of the parties that the transactions
-------------                                                           
contemplated hereby constitute the sale of the Transferred Interest, conveying
good title thereto free and clear of any Adverse Claims to PARCO, 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 Funding Agent, on behalf of PARCO and the
APA Banks, and the Transferor hereby grants to the Funding Agent, on behalf of
PARCO and the APA Banks, 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
respect thereto, and together with all of the Transferor's rights under the
Receivables Purchase Agreement with respect to the Receivables and with respect
to any obligations thereunder of the Originator with respect to the Receivables,
and that this Agreement shall constitute a security agreement under applicable
law.  The Transferor hereby assigns to the Funding Agent, on behalf of PARCO and
the APA Banks, all of its rights and remedies under the Receivables Purchase
Agreement with respect to the Receivables and with respect to any obligations
thereunder of the Originator with respect to the Receivables.  The Transferor
agrees that it shall not give any consent or waiver required or permitted to be
given 

                                       58
<PAGE>
 
under the Receivables Purchase Agreement without the prior consent of the
Funding Agent.

          SECTION IX.11.  Waiver of Setoff.  Each of the Funding Agent, the
                          ----------------

                          ---------------------                              
and as Administrative Agent for PARCO, as issuing and paying agent for PARCO's
Commercial Paper, as provider of other backup facilities for PARCO, and may
provide other services or facilities from time to time (the "Chase Roles").
                                                             -----------    
Without limiting the generality of Section 4.8, each of the parties hereto
hereby acknowledges and consents to any and all Chase Roles, waives any
objections it may have to any actual or potential conflict of interest caused by
Chase's acting as the Funding Agent or as an APA Bank under the Asset Purchase
Agreement and acting as or maintaining any of the Chase Roles, and agrees that
in connection with any Chase Role, Chase may take, or refrain from taking, any
action which it in its discretion deems appropriate.

          SECTION IX.13.  Liability of Funding Agent.  Notwithstanding any
                          --------------------------                      
provision of this Agreement:  (i) the Funding Agent shall not have any
obligations under this Agreement other than those specifically set forth herein,
and no implied obligations of the Funding Agent shall be read into this
Agreement; and (ii) in no event shall the Funding Agent be liable under or in
connection with this Agreement for indirect, special, or consequential losses or
damages of any kind, including lost profits, even if advised of the possibility
thereof and regardless of the form of action by which such losses or damages may
be claimed.  Neither the Funding Agent nor any of its directors, officers,
agents or employees shall be liable for any action taken or omitted to be taken
in good faith by it or them under or in connection with this Agreement, except
for its or their own gross negligence or willful misconduct.  Without limiting
the foregoing, the Funding Agent (a) may consult with legal counsel (including
counsel for PARCO), 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, (b) shall not be responsible to PARCO, the Transferor, the Originator
or the Collection Agent for any statements, warranties or representations made
in or in connection with this Agreement or the other Transaction Documents, (c)

Collection Agent for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of 

                                       59
<PAGE>
 
this Agreement or the other Transaction Documents, (d) shall incur no liability
under or in respect of any of the Commercial Paper or other obligations of PARCO
under this Agreement or the other Transaction Documents and (e) shall incur no
liability under or in respect of this Agreement or the other Transaction
Documents by acting upon any notice (including notice by telephone), consent,
certificate or other instrument or writing (which may be by facsimile) believed
by it to be genuine and signed or sent by the proper party or parties.
Notwithstanding anything else herein or in the other Transaction Documents, it
is agreed that where the Funding Agent may be required under this Agreement or
the other Transaction Documents to give notice of any event or condition or to
take any action as a result of the occurrence of any event or the existence of
any condition, the Funding Agent agrees to give such notice or take such action
only to the extent that it has actual knowledge of the occurrence of such event
or the existence of such condition, and shall incur no liability for any failure
to give such notice or take such action in the absence of such knowledge.

[Name and Address
 of Lock-Box Bank]


     Re:  [COLLECTION AGENT]
          Lock-Box Account
          No[s]. ___________

Ladies and Gentlemen:

          [COLLECTION AGENT] ("COLLECTION AGENT") hereby notifies The First
National Bank of Chicago that in connection with certain transactions involving
its accounts receivable, it has transferred exclusive ownership and dominion of
its lock-box account no[s]. __________ maintained with you (collectively the
"Accounts") to MP Receivables Company ("Transferor"), which then transferred
exclusive ownership and dominion of the Accounts to The Chase Manhattan Bank, as
funding agent (the "Funding Agent"), and that [COLLECTION AGENT] and Transferor
will transfer exclusive control of the Accounts to the Funding Agent effective
upon delivery to you of the Notice of Effectiveness (as hereinafter defined).
The Lockbox Service Terms dated _________ are incorporated into this Agreement
by reference; provided, however, in the event of a conflict between the
provisions of the Lockbox Service Terms and this Agreement, the provisions of
this Agreement shall control.

          In furtherance of the foregoing, [COLLECTION AGENT], Transferor and
the Funding Agent hereby instruct you, beginning on the date of your receipt of
the Notice of Effectiveness:  (i) to collect the monies, checks, instruments and
other items of payment mailed to the Accounts; (ii) to deposit into the Accounts
all such monies, checks, instruments and other items of payment or all funds
collected with respect thereto (unless otherwise instructed by the Funding
Agent); and (iii) to transfer all funds deposited and collected in the Accounts
pursuant to instructions given to you by the Funding Agent from time to time.

          You are hereby further instructed:  (i) unless and until the Funding
Agent notifies you to the contrary at any time after your receipt of the Notice
of Effectiveness, to 


                                      D-1
<PAGE>
 
make such transfers from the Accounts at such times and in such manner as
[COLLECTION AGENT], in its capacity as collection agent for the Funding Agent
and Transferor, shall from time to time instruct to the extent such instructions
are not inconsistent with the instructions set forth herein, and (ii) to permit
[COLLECTION AGENT] (in its capacity as collection agent for the Funding Agent
and Transferor), Transferor and the Funding Agent to obtain upon request any
information relating to the Accounts, including, without limitation, any
information regarding the balance or activity of the Accounts.

          Each of [COLLECTION AGENT] and Transferor also hereby notifies you
that, beginning on the date of your receipt of the Notice of Effectiveness and
notwithstanding anything herein or elsewhere to the contrary, the Funding Agent,
and not the Collection Agent or Transferor, shall be irrevocably entitled to
exercise any and all rights in respect of or in connection with the Accounts,
including, without limitation, the right to specify when payments are to be made
out of or in connection with the Accounts.  The Funding Agent has a continuing
interest in all of the checks and their proceeds and all monies and earnings, if
any, thereon in the Accounts, and you shall be the Funding Agent's agent for the
