(or similar phrase) refers only to funds in the administrative sub-accounts of
those accounts that are allocated to Series 1998-3. Unless the context otherwise

Documents shall be deemed to include a reference to the Certificate Purchase
Agreement.

         (c) Each capitalized term defined below relates only to the Series
1998-3 Certificates and to no other Series of Certificates. Whenever used in
this Supplement, the following words and phrases shall have the following
meanings:

         "Adjusted Carrying Cost Reserve" means the product of (a) the Carrying

         Amount, to the Equalization Account in an amount sufficient to reduce
         the Net Invested Amount to an amount equal to the Base Amount; and



                                                                         page 25

                  third, if there is a Distribution Shortfall with respect to
         any Series (other than Series 1998-1 and Series 1998-3) on such
         Business Day, to Trustee, for distribution to the applicable accounts
         or Persons specified in the Supplement with respect to such Series, the
         lesser of (x) the amount of such Distribution Shortfall and (y) the
         amount of funds available pursuant to this clause third, it being
         understood that if the Distribution Shortfalls for all Series (other
         than Series 1998-1 and Series 1998-3) exceed the amount of funds
         available pursuant to this clause third, then such funds shall be
         allocated to such Series pro rata based on their respective Series
         Collection Allocation Percentages (as defined in the Supplements for
         such Series).

                  On such Business Day, Servicer shall allocate the remainder of
         the Daily Series Collections to Transferor.

         If, on any day, the amount of Daily Series Collections that is then
allocated to the Carrying Cost Account is less than the amount of Daily Series
Collections that is then required to be allocated to the Carrying Cost Account,
Servicer shall reallocate such Daily Series Collections on such day first to the
Monthly Trustee Payment Amount and Transition Costs, if any, and then to one or
more of the obligations contemplated by priority first of the second preceding
sentence.

         SECTION 4.4 Allocations of Daily Series Collections During an
Amortization Period. On each Business Day falling in an Amortization Period, (a)
Servicer shall allocate to Series 1998-3 (i) the Daily Series Collections, (ii)
the amount of funds then available on account of a Distribution Shortfall (with
respect to Series 1998-3) pursuant to the Supplements for any other Series
(other than Series 1998-1) for the following purposes, in the priority indicated
(and to the extent of Daily Series Collections and such other funds available),
and (iii) at the option of Transferor, any New Issuance Proceeds specified in
writing by Transferor to Servicer and Trustee (provided that such New Issuance
Proceeds shall be paid directly to Trustee by one or more placement agents,
underwriters or initial Investor Certificateholders, as the case may be, of the
new Series), (b) Servicer shall indicate such allocation in the Daily Report
delivered on such Business Day, and (c) in accordance with such Daily Report,
Trustee shall remit or hold funds as follows:

                  first, to the Carrying Cost Account to the extent that the
         balance therein is less than the amount of Current Carrying Costs
         (other than any Servicing Fee payable to any AmeriServe Person) payable
         on the Distribution Date relating to the Calculation Period during
         which such Business Day falls;

                  second, to the Principal Funding Account, (i) if neither
         Section 4.9 nor Section 7.1 applies, an amount equal to the excess, if
         any, of (x) the Series 1998-3 Invested Amount over (y) the balance of
         the Principal Funding Account, (ii) if Section 4.9 applies, an amount
         equal to the excess, if any, of (x) the sum of the Outstanding
         Principal Balances of the Series 1998-3 Certificates plus the
         applicable Prepayment Premium, over (y) the balance of the Principal
         Funding Account, and (iii) if Section 7.1 applies, an amount equal 



                                                                         page 26
<PAGE>   31

         to the excess, if any, of (x) the Outstanding Principal Balances of the
         Series 1998-3 Certificates over (y) the balance of the Principal
         Funding Account;

                  third, to the Carrying Cost Account to the extent that the
         balance therein is less than the amount of Current Carrying Costs
         (including any Servicing Fee payable to any AmeriServe Person);

                  fourth, if there is a Distribution Shortfall with respect to
         any Series (other than Series 1998-1 and Series 1998-3) on such
         Business Day, to Trustee, for distribution to the applicable accounts
         or Persons specified in the Supplement with respect to such Series, the
         lesser of (x) the amount of such Distribution Shortfall and (y) the
         amount of funds available pursuant to this clause fourth, it being
         understood that if the Distribution Shortfalls for all Series (other
         than Series 1998-1 and Series 1998-3) exceed the amount of funds
         available pursuant to this clause fourth, then such funds shall be
         allocated to such Series pro rata based on their respective Series
         Collection Allocation Percentages; and

                  fifth, the balance to Transferor.

         SECTION 4.5 Withdrawals from the Equalization Account.

         (a) On any Business Day during the Revolving Period on which no Early
Amortization Event (or Unmatured Early Amortization Event) exists, Servicer may
instruct Trustee in writing to withdraw (and upon receipt of such instruction
Trustee shall withdraw) funds from the Equalization Account with respect to
Series 1998-3 and apply such funds as Daily Series Collections, so long as the
Net Invested Amount would not exceed the Base Amount after giving effect to such
transfer and application.

         (b) On the first day of the Amortization Period, Servicer shall
instruct Trustee to transfer (and Trustee shall transfer) the entire balance in
the Equalization Account to the Principal Funding Account.

         SECTION 4.6 Available Subordinated Amount. (a) If an Amortization
Period begins, Servicer shall promptly calculate the Available Subordinated
Amount as of the Amortization Period Calculation Date and report such amount in
the Daily Report for the first day in the Amortization Period. Servicer shall
also calculate the Available Subordinated Amount as of each Cut-Off Date falling
in the Amortization Period, such calculation to be reflected in the related
Monthly Report.



                                                                         page 27
<PAGE>   32

         (b) The Available Subordinated Amount as of the Amortization Period
Calculation Date shall equal the product of (x) the Investor Allocation
Percentage, multiplied by (y) the result of:

                  (i) the product of the Net Eligible Receivables at the opening
         of business on the Amortization Period Calculation Date, multiplied by
         the Series Collection Allocation Percentage on that date; minus

                  (ii) the sum of (i) the lesser of (A) the Base Amount plus the
         amount, if any, on deposit in the Equalization Account and the
         Principal Funding Account, and (B) the Net Invested Amount and (ii) the
         Carrying Cost Receivables Reserve at the opening of business on the
         Amortization Period Calculation Date.

         (c) The Available Subordinated Amount, as of any Cut-Off Date in the
Amortization Period, shall equal the result of:

                  (i) the Available Subordinated Amount as of the preceding
         Cut-Off Date (or as of the Amortization Period Calculation Date, in the
         case of the first Cut-Off Date falling in the Amortization Period);
         minus

                  (ii) the Investor Allocable Loss Amount with respect to the
         ASA Measuring Period ending on that Cut-Off Date; minus

                  (iii) any Investor Allocable Dilution with respect to the ASA
         Measuring Period ending on that Cut-Off Date; plus

                  (iv) subject to Sections 4.7 and 4.8, the Investor Allocable
         Recoveries and Investor Allocable Dilution Adjustments with respect to
         the ASA Measuring Period ending on that Cut-Off Date.

         (d) Notwithstanding the foregoing, in no event shall the Available
Subordinated Amount at any time be less than zero or greater than the initial
Available Subordinated Amount calculated pursuant to subsection (b).

         SECTION 4.7 Write-Offs and Recoveries. (a) In each Monthly Report
required to be delivered during the Amortization Period, Servicer shall
calculate the Investor Write-Offs and the Investor Allocable Recoveries for the
most recently ended ASA Measuring Period.

         (b) If the Investor Write-Offs calculated in any Monthly Report exceed
zero, the Series 1998-3 Invested Amount shall be reduced by the amount of the
Investor Write-Offs with effect from the related Distribution Date. Any such
reduction shall be allocated first to the Class C Invested Amount until the
Class C Invested Amount has been reduced to zero, second to the Class B Invested
Amount until the Class B Invested Amount has been reduced to zero, and third to
the Class A Invested Amount until the Class A Invested Amount has been reduced
to zero.


                                                                         page 28
<PAGE>   33

         (c) If the Series 1998-3 Invested Amount has been reduced on account of
any Investor Write-Offs, then any Investor Allocable Recoveries with respect to
any Calculation Period ending after the reduction takes place shall be applied
to reinstate the Series 1998-3 Invested Amount, to the extent of such prior
reductions that have not previously been reinstated, with effect from the
related Distribution Date. Any such reinstatement shall be allocated first to
the Class A Invested Amount until all prior reductions to the Class A Invested
Amount on account of Investor Write-Offs have been reinstated, second to the
Class B Invested Amount until all prior reductions to the Class B Invested
Amount on account of Investor Write-Offs have been reinstated, and third to the
Class C Invested Amount until all prior reductions to the Class C Invested
Amount have been reinstated.

         (d) If Investor Allocable Recoveries are applied pursuant to subsection
(c) to reinstate the Series 1998-3 Invested Amount on any Distribution Date,
then Investor Allocable Recoveries shall be applied to increase the Available
Subordinated Amount on the same Distribution Date only to the extent of the
excess, if any, of the Investor Allocable Recoveries, minus the amount of
Investor Allocable Recoveries so applied.

         SECTION 4.8 Certain Dilution in an Amortization Period. (a) In each
Monthly Report required to be delivered during the Amortization Period, Servicer
shall calculate the Investor Allocable Dilution and the Series Allocable
Dilution Adjustments for the most recently ended ASA Measuring Period.

         (b) If the Available Subordinated Amount or the Series 1998-3 Invested
Amount has been reduced on account of any Investor Allocable Dilution, then any
Series Allocable Dilution Adjustments with respect to any Calculation Period
ending after the reduction takes place (the "Investor Allocable Dilution
Adjustments") shall be allocated (x) first, to reinstate the Series 1998-3
Invested Amount (with the same allocation among Series 1998-3 Certificateholders
as is described in subsection 4.7(c)), and (y) second, to reinstate the
Available Subordinated Amount, in each case to the extent not previously
reinstated. Any funds so allocated on any day shall be distributed in accordance
with the priorities set forth in Section 4.4.

         SECTION 4.9 Optional Termination; Prepayment Premium. (a) On any
Business Day falling in the Revolving Period, Transferor shall have the right to
deliver an irrevocable written notice (an "Optional Termination Notice") to
Trustee and Servicer in which Transferor declares that the Revolving Period
shall terminate on the Distribution Date (the "Optional Termination Date") set
forth in such notice (which Distribution Date, in any event, shall be a date
which is (i) at least thirty days from the date on which such notice is
delivered and (ii) prior to the Expected Revolving Period Termination Date). It
shall be a condition precedent to the occurrence of the Optional Termination
Date that the Transferor shall have provided to Trustee and the Rating Agencies
a legal opinion, reasonably satisfactory in form and substance to Trustee and
the Rating Agencies, to the effect that the payments contemplated by this
Section 4.9 would not constitute a fraudulent conveyance. On the Business Day
prior to the Optional Termination Date, to the extent that sufficient funds are
not available pursuant to Section 5.1 in the Carrying 



                                                                         page 29

Cost Account and the Principal Funding Account for the purpose of repaying the
Outstanding Principal Balances of the Series 1998-3 Certificates in full and
paying all accrued but unpaid interest thereon and paying the Transferor
Optional Prepayment Premium (defined below), Transferor shall pay to the Trustee
for distribution to the Series 1998-3 Certificateholders (solely from funds
available to Transferor which are not otherwise needed to be applied to the
payment of any amounts by Transferor pursuant to the Pooling Agreement or any
Supplement), an amount equal to the sum of: (i) the Outstanding Principal
Balances of the Series 1998-3 Certificates; plus (ii) all accrued but unpaid
interest thereon plus (iii) an amount calculated by Transferor equal to the
present value of a series of payments equal to the sum of (x) the product of (A)
the Outstanding Principal Balances of the Class A Certificates and (B) the
Certificate Spread for the Class A Certificates, payable monthly on each
Distribution Date in arrears from the Optional Termination Date through the

Optional Termination Date, plus (y) the product of (A) the Outstanding Principal
Balances of the Class B Certificates and (B) the Certificate Spread for the
Class B Certificates, payable monthly on each Distribution Date in arrears from

Optional Termination Date (the sum of clauses (x), (y) and (z) of this sentence
being referred to as the "Transferor Optional Termination Prepayment Premium").

         (b) Trustee shall give prompt written notice of its receipt of the
Optional Termination Notice or the Termination of Sale Notice to the Series
1998-3 Certificateholders and each Rating Agency.

         (c) On each Distribution Date in an Amortization Period resulting from
the delivery of a Termination of Sale Notice, the Series 1998-3
Certificateholders shall be entitled to receive, in addition to the other
amounts payable under this Supplement (to the extent not previously paid
pursuant to Section 5.1), an amount calculated by Transferor equal to the
present value of a series of payments equal to the sum of (x) the product of (A)
the Outstanding Principal Balances of the Class A Certificates and (B) the
Certificate Spread for the Class A Certificates, payable monthly on each
Distribution Date in arrears from the first Distribution Date following the
delivery of the Termination of Sale Notice through the Expected Revolving Period
Termination Date and discounted at a rate equal to One-Month LIBOR being used to
calculate the Class A Certificate Rate on the first Distribution Date following

delivered in connection with the Series 1998-3 Certificates, the term "Tax
Opinion" shall have the meaning specified below:

                  "Tax Opinion" means, with respect to any action, an Opinion of
         Counsel to the effect that, for Federal income tax and applicable state
         income and franchise tax purposes, (a) such action shall not adversely
         affect the characterization of the Class A Certificates or Class B
         Certificates as debt and the Class C Certificates as debt or
         partnership interests, (b) following such action the Trust would not be
         treated as an association (or publicly traded partnership) taxable as a

Certificateholder by 1:00 p.m., New York City time on each Distribution Date by
wire transfer of immediately available funds to an account maintained by such
Series 1998-3 Certificateholder with a bank in the United States (or, in the
case of any Series 1998-3 Certificates which are represented by Book-Entry
Certificates, at such earlier time as may be required to guarantee that the
Clearing Agency will receive payment in same-day funds by 2:30 p.m. New York
City time on such Distribution Date); provided that such Holder notified the
Trustee (if not the Trustee) in writing as to such account at least five
Business Days prior to such Distribution Date (such notice to remain effective
with respect to a Holder until different instructions are received by the
Trustee). Distributions to Series 1998-3 Certificateholders which do not qualify

Certificateholders on a Distribution Date, the status of a Person as a Series
1998-3 Certificateholder shall be determined as of the preceding Record Date.



                                                                         page 33

         SECTION 5.2 Payments in Respect of Transferor Certificate. On each day
on which funds are allocated for this purpose pursuant to Sections 4.3 and 4.4,
Trustee shall, in accordance with instructions set out in the applicable Daily
Report, distribute to Transferor all funds allocated for that purpose in
accordance with those Sections. In addition, upon termination of this Supplement
in accordance with Section 8.9, any additional funds on deposit in the Carrying
Cost Account, the Equalization Account or the Principal Funding Account shall
similarly be paid to Transferor in respect of the Transferor Certificate.

         SECTION 5.3 Daily Reports and Monthly Reports. (a) Each Daily Report
and Monthly Report shall be substantially in the applicable form set out in
Exhibit D or E or in such other form as may be consistent with the terms of this
Supplement and the Pooling Agreement. Copies of each Monthly Report shall be
provided free of charge on each Report Date by the Servicer to the Holders of
Series 1998-3 Certificates. Each Daily Report shall report the required
information for all outstanding Series.

         (b)      Notwithstanding any other provision of this Supplement:

                  (i)   In the event that a calculation or determination to be
         made with respect to periods prior to the Closing Date refers to a
         Daily Report or Monthly Report, such calculation or determination shall
         be made even though Daily Reports and Monthly Reports were not required
         to be delivered pursuant to this Supplement prior to the Closing Date.
         By way of example, the "ADR" referred to in the definition of Dilution
         Reserve Ratio shall be calculated for purposes of periods prior to the
         Closing Date even though the definition of Dilution Ratio refers to a
         calculation in a Monthly Report.

                  (ii)  Any calculation or determination which relates to a
         Cut-Off Date and which is to be made with respect to periods or dates
         prior to the Cut-Off Date occurring in September 1997 (with respect to
         AmeriServe) or February 1998 (with respect to ProSource) shall be made
         instead with respect to Unmodified End Dates relating to such periods
         or dates. "Unmodified End Date" means the end of a fiscal month of a
         Seller and, to the extent relevant, the end of "Periods" historically
         used by PFS in connection with its servicing operations.

                  (iii) Servicer at all times shall use its best efforts to
         estimate the items described in clause (b) of the definition of Net
         Eligible Receivables; provided that the fact that Servicer is permitted
         to make such estimates shall not limit the effect of any
         indemnification or other provision in any Transaction Document.

This Section 5.3 shall not limit the obligation of Servicer to make the
allocations and calculations required by this Supplement on a daily basis.

         SECTION 5.4 Annual Tax Information. During January (and on or before
January 31) of each calendar year, Servicer, on behalf of Trustee, shall furnish
or cause to be furnished to each 



                                                                         page 34
<PAGE>   39

Person who at any time during the preceding calendar year was a Holder the
information for the preceding calendar year, or the applicable portion thereof
during which the Person was a Holder, as is required to be provided by an issuer
of indebtedness under the Internal Revenue Code to the holders of the issuer's
indebtedness and such other customary information as is necessary to enable such
Holders to prepare their federal income tax returns. Notwithstanding anything to
the contrary contained in this Agreement, Trustee shall, to the extent required
by applicable law, from time to time furnish to the appropriate Persons, at
least five Business Days prior to the end of the period required by applicable
law, the information required to complete a Form 1099-INT.

         SECTION 5.5 Periodic Perfection Certificate. During December (and on or
before December 31) of each calendar year, Servicer, on behalf of Trustee, shall
furnish or cause to be furnished to Trustee and the Agent an Officer's
Certificate setting forth a list of all changes in (i) the name, identity or
corporate structure of Transferor or any Seller and (ii) the chief executive
office of Transferor or any Seller (or in the place of business of Transferor or
any Seller that has only one place of business) that have taken place since the
date of the Officer's Certificate most recently delivered pursuant to this
Section 5.5, or indicating that no such events have taken place, and stating in
each case what filings of UCC financing statements, or amendments thereto,
relating to the Transaction Documents have been made in connection with each
such event (identifying the date and filing index numbers for each). Any
financing statement identified in such an Officer's Certificate delivered to
Trustee shall be deemed to have been identified to Trustee in writing for
purposes of subsection 11.1(c)(v) of the Pooling Agreement. If any such new UCC
financing statements are filed, Servicer shall cause Trustee to be named as
secured party (in the case of any filing against Transferor) or assignee of the
secured party (in the case of any filing against a Seller).

         period of five Business Days, or any other representation or warranty
         made by Transferor, Servicer, any Seller or Guarantor in any

         failed to make the cash payments (if any) owed under Sections 3.1 and
         3.5 of the Purchase Agreement in respect of such mistake or breach (it
         being understood that certain of such mistakes or breaches may result
         in a non-cash adjustment under the Purchase Agreement);

                  (c) a Bankruptcy Event shall occur with respect to Transferor,
         Servicer, Guarantor or any Seller, or Transferor shall become unable,
         for any reason, to transfer Receivables or other Transferred Assets to
         Trustee in accordance with the provisions of this Supplement and the

         of a bankruptcy proceeding being filed against Transferor or any
         Seller, then, on and after the day on which the bankruptcy proceeding

Series 1998-3 Certificateholders, Trustee shall promptly), by notice given in
writing to Transferor and Servicer, declare that an Early Amortization Period
has commenced (and the Early Amortization Period shall commence immediately as

                                                                         page 37

ARTICLE VII  OPTIONAL REDEMPTION; INDEMNITIES

         SECTION 7.1 Optional Redemption of Investor Interests. On any
Distribution Date occurring during the Amortization Period with respect to the
Series 1998-3 Certificates on or after the date that the Outstanding Principal
Balance of the Series 1998-3 Certificates is reduced to ten percent (10%) or
less of the Outstanding Principal Balance of the Series 1998-3 Certificates as
of the commencement of the Amortization Period, Transferor shall have the option
to redeem the Series 1998-3 Series Interest, provided that, on or prior to such
Distribution Date, Transferor shall have furnished to Trustee and the Rating
Agencies a legal opinion, in form and substance reasonably satisfactory to
Trustee and the Rating Agencies, to the effect that the payment of such
redemption price does not constitute a fraudulent conveyance. The redemption
price shall be an amount equal to the sum of (a) the Outstanding Principal
Balances of the Series 1998-3 Certificates, plus (b) accrued and unpaid interest
on the Series 1998-3 Certificates (and accrued and unpaid interest with respect
to interest that was due but not paid on any prior Distribution Date) through
the day preceding such Distribution Date in accordance with Section 4.1. Upon
the tender of the outstanding Series 1998-3 Certificates, Trustee shall
distribute such amounts, together with all funds on deposit in the Principal
Funding Account that are allocable to the Series 1998-3 Certificates, to the
Series 1998-3 Certificateholders on the next Distribution Date in repayment of
the principal amount and accrued and unpaid interest owing to the Series 1998-3
Certificateholders. Following any redemption, the Series 1998-3
Certificateholders shall have no further rights with respect to the Receivables,
subject to Section 8.9. In the event that Transferor fails for any reason to
deposit such redemption price in the Principal Funding Account, payments shall
continue to be made to the Series 1998-3 Certificateholders in accordance with
the terms of the Pooling Agreement and this Supplement.

         SECTION 7.2 Indemnification by Transferor. Transferor hereby agrees to
indemnify the Trust, Trustee, the Initial Purchasers, each Holder of a Series
1998-3 Certificate and each of the successors, permitted transferees and assigns
of any such Person and all officers, directors, shareholders, controlling
Persons, employees, affiliates and agents of any of the foregoing (each of the
foregoing Persons (other than the Transferor) individually being called a
"Transferor Indemnified Party"), forthwith on demand, from and against any and
all damages, losses, claims (whether on account of settlements or otherwise, and
whether or not the relevant Transferor Indemnified Party is a party to any
action or proceeding that gives rise to any Transferor Indemnified Losses (as
defined below)), judgments, liabilities and related reasonable costs and
expenses (including reasonable Attorney Costs) (all of the foregoing
collectively being called "Transferor Indemnified Losses") awarded against or
incurred by any of them that arise out of or relate to this Agreement, any other
Transaction Document or any of the transactions contemplated herein or therein
or the use of proceeds herefrom or therefrom (including without limitation any
Transferor Indemnified Losses relating to any Adverse Claim, without regard to
whether such Adverse Claim was a Permitted Adverse Claim).

         Notwithstanding the foregoing, in no event shall any Transferor
Indemnified Party be indemnified for any Transferor Indemnified Losses (i)
resulting from gross negligence or willful 




                                                                         page 38
<PAGE>   43

misconduct on the part of such Transferor Indemnified Party (or the gross
negligence or willful misconduct on the part of any of its officers, directors,
employees, affiliates or agents), (ii) to the extent they include Transferor
Indemnified Losses in respect of Receivables and reimbursement therefor that
would constitute credit recourse to Transferor for the amount of any Receivable
or Related Transferred Asset not paid by the related Obligor, or (iii) to the
extent they are or result from taxes (including interest and penalties thereon)
asserted with respect to (A) distributions on the Series 1998-3 Certificates,
(B) franchise or withholding taxes imposed on any Transferor Indemnified Party
other than the Trust or Trustee in its capacity as Trustee, or (C) federal or
other income taxes on or measured by the net income of such Transferor
Indemnified Party and costs and expenses in defending against the same.

         If for any reason the indemnification provided in this section is
unavailable to a Transferor Indemnified Party or is insufficient to hold a
Transferor Indemnified Party harmless, then Transferor shall contribute to the
amount paid by the Transferor Indemnified Party as a result of any loss, claim,
damage or liability in such proportion as is appropriate to reflect not only the
relative benefits received by the Transferor Indemnified Party on the one hand
and Transferor on the other hand, but also the relative fault (if any) of the
Transferor Indemnified Party and Transferor and any other relevant equitable
considerations.

         Notwithstanding any provisions contained in any Transaction Document to
the contrary, Transferor shall not, and shall not be obligated to, pay any
amount pursuant to this Section unless funds are allocated for such payment
pursuant to Article IV of this Supplement. Any amount which Transferor does not
pay pursuant to the operation of the preceding sentence shall not constitute a
claim (as defined in SECTION101 of the Bankruptcy Code) against or corporate
obligation of Transferor for any such insufficiency.

         SECTION 7.3 Indemnification by Servicer. Servicer agrees that each of
the Initial Purchasers, each Holder of a Series 1998-3 Certificate and each
other Transferor Indemnified Party shall be an "Indemnified Party" for purposes
of the Pooling Agreement.

Tier-3 Obligor, Tier-4 Obligor and Tier-5 Obligor (the "Tier Definitions"), if
an Obligor has no short-term or long-term unsecured debt rating from S&P, and
such Obligor does have a short-term or long-term unsecured debt rating from
Moody's, then: (x) Moody's shall be deemed to be a Rating Agency with respect to
such Obligor for purposes of the short-term and long-term unsecured debt ratings
set forth in the Tier Definitions, (y) (1) if the short-term unsecured
indebtedness of such Obligor is rated "P-1" by Moody's, then the short-term
unsecured debt rating relating to S&P set forth in the Tier Definitions shall be
deemed to be not less than "A-1" by S&P, and (2) except as provided in clause
(1), any short-term or long-term unsecured debt rating category relating to S&P
set forth in the Tier Definitions shall be deemed to be a corresponding rating
from Moody's which is one subcategory below the applicable short-term or
long-term unsecured rating category relating to S&P, and (z) such Obligor shall
in no case be considered to be a Tier- 1 Obligor.

         SECTION 8.6 Waiver. Each of Trustee, the Certificateholders and the
Certificate Owners agrees and acknowledges that Mayer, Brown & Platt represents
the Initial Purchasers, Bank of America and Affiliates of Bank of America in

relating thereto. Mayer, Brown & Platt is entitled to rely on this Section 8.6.

                  (ii)  we are purchasing the Certificates for our own account
         or for the account of one or more other Institutional Accredited
         Investors;

                  (iii) we are taking delivery of Certificates in an amount of
         at least $500,000 for our own account or for each separate account for
         which we are acting;

                  (iv)  we have such knowledge and experience in financial and
         business matters, we are capable of evaluating the merits and risks of
         purchasing Certificates and we, or the account for which we are
         purchasing Certificates, can bear the economic risks of investing in
         the Certificates for an indefinite period of time;

                  (v)   we are acquiring Certificates for investment and not 
         with a view to any distribution thereof in a transaction that would
         violate the Securities Act or the securities laws of any state of the

         the Trustee, the Servicer and any successor Servicer that one or any
         combination of the following statements is an accurate representation
         as to all sources of funds to be used to pay the purchase price of the
         Certificates: (i) if we are an insurance company, the source of funds
         to be used by us is an "insurance company general account" within the
         meaning of Department of Labor Prohibited Transaction Class Exemption
         ("PTCE") 95-60 (issued July 12, 1995) and there is no Plan with respect
         to which the amount of the general account reserves and liabilities for
         all contracts held by or on behalf of such Plan, exceed ten percent
         (10%) of the total reserves and liabilities of such general account
         (exclusive of separate account liabilities) plus surplus, as set forth
         in the NAIC Annual Statement (within the meaning of PTCE 95-60) filed
         by us with our state of domicile; (ii) such funds constitute assets of
         one or more insurance company pooled separate accounts within the
         meaning of PTCE 90-1 (issued January 29, 1990) maintained by us and
         there is no Plan whose assets in such separate account exceed 10% of
         the total assets of such separate account as of the date of such
         purchase; (iii) such funds constitute assets of a bank collective
         investment fund within the meaning of PTCE 91-38 (issued June 12, 1991)
         maintained by us, and there is no employee benefit plan whose assets in
         such collective investment fund exceed 10% of the total assets of such
         collective investment fund as of the date of such purchase; (iv) we are
         acquiring

         the Series 1998-3 Certificates for the account of one or more pension
         funds, trust funds or agency accounts, each of which is a "governmental
         plan" as defined in Section 3(32) of ERISA and the purchase and holding
         of the Series 1998-3 Certificates by us will not violate any state or
         other law relating to such governmental plan; (v) the source of funds
         is managed by a "qualified professional asset manager" or "QPAM" (as
         defined in Part V of PTCE 84-14, issued March 13, 1984), or an "INHAM"
         (as defined in part V of PTCE 96-23, issued April 10, 1996) and the
         purchase and holding of the Series 1998-3 Certificates by us is exempt
         from the prohibited transaction rules of Section 4975(c) of the Code
         and section 406(a) of ERISA under PTCE 84-14 or PTCE 96-23; (vi) we are
         an insurance company general account and our purchase and holding of
         the Series 1998-3 Certificates is exempt from the prohibited
         transaction rules of section 4975(c) of the Code and Section 406(a) of
         ERISA under section 401(c) of ERISA, the conditions of which are met
         and we will transfer our interest in the Series 1998-3 Certificates if
         and at such time as such representation is no longer true and correct;
         (vii) the proposed acquisition or transfer will qualify for a statutory
         or administrative prohibited transaction exemption under ERISA and the
         Code or will not give rise to a transaction described in Section 406(a)
         of ERISA or Section 4975(c)(1) of the Code for which a statutory or
         administrative exemption is unavailable; or (viii) such funds consist
         of funds which do not constitute "plan assets" within the meaning of
         Department of Labor Regulation 29 C.F.R. Section 2510.3-101.

         We understand that the Certificates are being offered in a transaction
not involving any public offering within the meaning of the Securities Act and
that the Certificates have not been registered under the Securities Act, and we
agree, on our own behalf and on behalf of each account for which we acquire any
Certificates, that such Certificates may be resold, pledged or transferred only
(i) in a transaction meeting the requirements of Rule 144A ("Rule 144A") under
the Securities Act, to a person that we reasonably believe is a "qualified
institutional buyer" (as defined in Rule 144A) that purchases for its own
account (or for the account or accounts of a qualified institutional buyer) and
to whom notice is given that the resale, pledge or other transfer is being made
in reliance on Rule 144A or (ii) to a person that (A) is an Institutional
Accredited Investor, is taking delivery of such Certificates in an amount of at
least $500,000 and delivers a letter to you, in substantially the form of this
letter, or (B) is taking delivery of such Certificates pursuant to a transaction
that is otherwise exempt from the registration requirements of the Securities
Act, as confirmed in an opinion of counsel addressed to the Trustee and the
Transferor, which opinion and counsel must be satisfactory to the Trustee and
the Transferor.

         We understand that the Transfer Agent and Registrar will not be
required to accept for registration of transfer any Certificates, except upon
presentation of evidence satisfactory to the Transferor that the foregoing
restrictions on transfer have been complied with.

                                                                          page 3

Ladies and Gentlemen:

         We are delivering this letter in connection with the transfer of
$__________ of the Floating Rate Class C Term Certificates, Series 1998-3 (the
"Class C Certificates") issued by the AmeriServe Receivables Master Trust (the
"Trust") created under the Pooling and Servicing Agreement, dated as of July 1,
1997, as amended and restated as of July 28, 1998 (as the same may be further
amended, amended and restated or otherwise modified from time to time, the
"Pooling Agreement"), among AmeriServe Funding Corporation, a Delaware
corporation (the "Transferor"), AmeriServe Food Distribution, Inc., a Delaware
corporation, as servicer (the "Servicer"), and Norwest Bank Minnesota, National
Association, a national banking association, as trustee (the "Trustee"), and the
Series 1998-3 Supplement, dated as of December 18, 1998 (as the same may be
amended, amended and restated or otherwise modified from time to time, the
"Series 1998-3 Supplement"), to the Pooling Agreement among the Transferor, the
Servicer and the Trustee. Capitalized terms used herein without definition shall
have the meanings assigned thereto in the Series 1998-3 Supplement.

         We hereby represent, warrant and agree that: (1) (a) we are purchasing
the Class C Certificates for our own account and are the sole beneficial owner
of such Class C Certificates, (b) either (i) we are not, for federal income tax
purposes, a partnership, trust, 



                                      G-1

estate or "S Corporation" (as defined in the Code) (each a "Pass-Through
Entity") or (ii) we are, for federal income tax purposes, a Pass-Through Entity,
but after giving effect to our purchase of such Class C Certificates,
substantially all of the value of the assets of the Pass-Through Entity is not
attributable to the Pass-Through Entity's ownership interest in Certificates
issued by the Trust other than the Class A and Class B Certificates or the
Series 1998-4 Certificates, and (c) such Class C Certificates have not been
transferred through an "established securities market" within the meaning of
Section 7704(b) of the Code and such transfer, including a sale, pledge,
assignment, participation or subdivision, will not cause the Trust to be treated
as a publicly traded partnership for United States federal income tax purposes;
(2) if we are a Pass-Through Entity, we covenant that at all times,
substantially all of the value of the assets of the Pass-Through Entity will not
be attributable to the Pass-Through Entity's ownership interest in Certificates
issued by the Trust other than the Class A or Class B Certificates or the Series
1998-4 Certificates; (3) we are a "United States Person" as defined in Section
7701(a)(30) of the Code; (4) after such transfer, including a sale, pledge,
assignment, participation or subdivision, for purposes of Section 7704 of the
Code and the regulations promulgated thereunder, the Class C Certificates will
not be treated as owned by more than 20 Persons and the Trust will not be
treated as having more than 100 partners; and (5) if we transfer (including a
transfer constituting a sale, pledge, assignment, participation or subdivision)
any of the Class C Certificates, we will obtain from each purchaser or
transferee taking from us a letter containing the same representations and
agreements as set forth herein.

         We understand and agree that no initial or subsequent sale or other
transfer of a Class C Certificate may be made unless such sale or transfer (i)
is accompanied by delivery of a tax statement in the form of this letter, (ii)
is made to a "United States Person" as defined in Section 7701(a)(30) of the
Code, as certified in such tax statement, and (iii) will not cause the Trust to
be treated as a publicly traded partnership for United States federal income tax
purposes. Any attempted transfer, assignment, conveyance, participation or
subdivision in contravention of the preceding sentence shall be void ab initio
and the purported transferor, seller or subdivider of such Class C Certificate
shall continue to be treated as the Holder of such Class C Certificate for all
purposes of the Pooling Agreement and the Series 1998-3 Supplement.

         We represent to the Initial Purchasers, AmeriServe, the Trustee, the
Servicer and any successor Servicer that one or any combination of the following
statements is an accurate representation as to all sources of funds to be used
to pay the purchase price of the Class C Certificates: (i) if we are an
insurance company, the source of funds to be used by us is an "insurance company
general account" within the meaning of Department of Labor Prohibited
Transaction Class Exemption ("PTCE") 95-60 (issued July 12, 1995) and there is
no Plan with respect to which the amount of the general account reserves and
liabilities for all contracts held by or on behalf of such plan, exceed ten
percent (10%) of the total reserves and liabilities of such general account
(exclusive of separate account liabilities) plus surplus, as set forth in the
NAIC Annual Statement (within the meaning of PTCE 95-60) filed by us with our
state of domicile; (ii) such funds constitute assets of one 



                                      G-2
<PAGE>   87

or more insurance company pooled separate accounts within the meaning of PTCE
90-1 (issued January 29, 1990) maintained by us and there is no Plan whose
assets in such separate account exceed 10% of the total assets as of the date of
such purchase; (iii) such funds constitute assets of a bank collective
investment fund within the meaning of PTCE 91-38 (issued June 12, 1991)
maintained by us, and there is no employee benefit plan whose assets in such
collective investment fund exceed 10% of the total assets as of the date of such
purchase; (iv) we are acquiring the Series 1998-3 Certificates for the account
of one or more pension funds, trust funds or agency accounts, each of which is a
"governmental plan" as defined in Section 3(32) of ERISA and the purchase and
holding of the Series 1998-3 Certificates will not violate any state or other
law relating to such governmental plan; (v) the source of funds is managed by a
"qualified professional asset manager" or "QPAM" (as defined in Part V of PTCE
84-14, issued March 13, 1984), or an "INHAM" (as defined in part V of PTCE
96-23, issued April 10, 1996) and the purchase and holding of the Series 1998-3
Certificates is exempt from the prohibited transaction rules of Section 4975(c)
of the Code and section 406(a) of ERISA under PTCE 84-14 or PTCE 96-23; (vi) the
transferee is an insurance company general account and the purchase and holding
of the Series 1998-3 Certificates is exempt from the prohibited transaction
rules of section 4975(c) of the Code and Section 406(a) of ERISA under section
401(c) of ERISA, the conditions of which are met and we will transfer our
interest in the Series 1998-3 Certificates if and at such time as such
representation is no longer true and correct; (vii) the proposed acquisition or
transfer will qualify for a statutory or administrative prohibited transaction
exemption under ERISA and the Code or will not give rise to a transaction
described in Section 406(a) of ERISA or Section 4975(c)(1) of the Code for which
a statutory or administrative exemption is unavailable; or (viii) such funds
consist of funds which do not constitute "plan assets" within the meaning of
Department of Labor Regulation 29 C.F.R. Section 2510.3-101.

         We understand that this letter is required in connection with certain
laws. If administrative or other proceedings are commenced in connection with
which this letter is or would be relevant, we irrevocably authorize you to
produce this letter or a copy of this letter to any interested party in such
