     [AS AMENDED, PURSUANT TO AMENDMENT NO. 1 TO STOCK PURCHASE AGREEMENT]

                         FORM OF TAX ESCROW AGREEMENT
                         ----------------------------
                                        
     AGREEMENT made as of ____________, 1998 by and among Merkert American
Corporation (formerly known as Monroe, Inc.), a Delaware corporation ("Buyer"),
Robert Q. Crane, as Stockholders' Representative (as defined in the Purchase
Agreement (as defined below)), and State Street Bank and Trust Company, as
escrow agent (the "Escrow Agent"). Capitalized terms used herein and not
otherwise defined shall have the meaning provided in the Purchase Agreement, as
hereinafter defined.

     WHEREAS, Buyer, Merkert Enterprises, Inc., a Massachusetts corporation
("Merkert"), Eugene F. Merkert and the Merkert Stockholders are parties to a
Stock Purchase Agreement dated as of May 20, 1998 (the "Purchase Agreement");

     WHEREAS, pursuant to Section 1.4 of the Purchase Agreement, Buyer has
agreed to deposit an amount of cash with the Escrow Agent to hold, invest and
deliver pursuant to this Agreement; and

     WHEREAS, the Escrow Agent is willing to enter into this Agreement and
perform as required herein in consideration of the premises and the mutual
obligations and promises contained in this Agreement on the terms and subject to
the conditions set forth herein.

     NOW, THEREFORE, in consideration of these premises and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto hereby agree as follows.

     1.   Appointment of the Escrow Agent.  Buyer and the Stockholders'
          -------------------------------                              
Representative hereby appoint and designate State Street Bank and Trust Company
as Escrow Agent for the property described herein.  The Stockholders'
Representative shall serve as exclusive representative of the Stockholders with
respect to the Escrow Fund and this Agreement.

     2.   Escrow Fund; Amounts Earned on Escrow Fund.  Buyer shall deposit with
          ------------------------------------------                           
the Escrow Agent and the Escrow Agent agrees to accept
_________________________________ Dollars ($__________) to be held in a
designated separate account of the Escrow Agent (the "Escrow Account").  The
consideration deposited hereunder, inclusive of any earnings on the same, shall
be referred to as the "Escrow Fund."  The Escrow Fund shall be invested from
time to time in Eligible Investments (as defined in Section 22) pursuant to (and
as specified in) the written direction of Buyer received by the Escrow Agent
(which direction shall include maturity terms selected by Buyer).  The Escrow
Agent shall be entitled to presume that any maturity terms set forth in an
investment instruction from Buyer have been agreed to by Stockholders'
Representative.  The Escrow Agent is authorized to liquidate any such investment
at any time when necessary to pay any amount hereunder.  In no instance shall
the Escrow Agent have any liability for any loss on any such investment.
<PAGE>
 
     3.   Amounts Earned on Escrow Fund; Tax Matters.  All amounts earned, paid
          ------------------------------------------                           
or distributed with respect to the Escrow Fund (whether interest, dividends or
otherwise) shall become a part of the Escrow Fund and shall be held hereunder
upon the same terms as the original Escrow Fund.  The parties agree that (i) for
tax reporting purposes, and for any tax year, all interest or other income
earned from the investment of the Escrow Fund shall be allocable to Buyer and
(ii) to the extent permitted by applicable law, including Section 468B(g) of the
Internal Revenue Code of 1986, as amended, Buyer will include all amounts earned
on the Escrow Fund in its gross incomes for federal, state and local income tax
(collectively, "income tax") purposes and pay any income tax resulting
therefrom.  Buyer and the Stockholders also agree for income tax purposes to
treat all amounts distributed to the Stockholders from the Escrow Fund as
increases in the cash portion of the Total Consideration paid by Buyer to the
Stockholders (subject to the application of Section 483 and/or 1274 of the
Internal Revenue Code of 1986, as amended).  Buyer agrees to provide the Escrow
Agent with a certified tax identification number by signing and returning a Form
W-9 to the Escrow Agent prior to the date on which interest or other income is
first earned by the Escrow Fund.  The parties hereto understand that, in the
event that such tax identification numbers are not certified to the Escrow Agent
prior to the date on which any income is first earned on the Escrow Fund, the
Internal Revenue Code, as amended from time to time, may require withholding of
a portion of any interest or other income earned on the investment of the Escrow
Fund.

     4.   Distribution of Escrow Fund.  Distributions from the Escrow Fund shall
          ---------------------------                                           
be made as follows:

          (a)  Upon receipt by the Escrow Agent of joint written instructions
     signed by both Buyer and the Stockholders' Representative, the Escrow Agent
     shall make payments out of the Escrow Fund in accordance with such
     instructions in immediately available funds within five (5) business days
     after receipt of such instructions or as soon as possible thereafter.

          (b)  Upon receipt by the Escrow Agent of a certificate (an "Interim
     Distribution Certificate") signed by Buyer certifying that (i) enclosed
     therewith is a true, accurate and complete copy of a demand for payment
     (including any assessment or determination of an amount due), relating to
     one or more Audits, from the Internal Revenue Service (the "IRS") and/or
     any taxing authority of any state or locality, including the Massachusetts
     Department of Revenue (any such taxing authority, the "DOR") or (ii) Buyer
     reasonably believes the amount instructed to be paid therein is payable to
     the IRS and/or the DOR, relating to one or more Audits, and instructing the
     Escrow Agent to pay to the IRS and/or the DOR, as the case may be, the
     amount set forth in such Interim Distribution Certificate, which Interim
     Distribution Certificate shall be accompanied by the demand for payment, if
     any, the Escrow Agent shall make payments out of the Escrow Fund in
     accordance with such Interim Distribution Certificate in immediately
     available funds within five (5)
                                       2
<PAGE>
 
     business days after receipt of such Interim Distribution Certificate or as
     soon as possible thereafter.

          (c)  Upon receipt by the Escrow Agent of a certificate (a "Final
     Distribution Certificate") signed by Buyer certifying that (i) full and
     final settlements with the IRS and the DOR of all matters relating to the
     Audits have been reached, and (ii) either (A) enclosed therewith is a true,
     accurate and complete copy of a demand for payment (including any
     assessment or determination of an amount due) from the IRS and/or the DOR
     or (B) Buyer reasonably believes the amount instructed to be paid therein
     to the IRS and/or the DOR is payable to the IRS and/or the DOR, and
     instructing the Escrow Agent to (x) pay to the IRS and/or the DOR, as the
     case may be, the amount set forth in such Final Distribution Certificate
     and (y) pay in accordance with such Final Distribution Certificate the
     remaining balance, if any, of the Escrow Fund, the Escrow Agent shall make
     payments out of the Escrow Fund in accordance with such Final Distribution
     Certificate in immediately available funds within five (5) business days
     after receipt of such Final Distribution Certificate or as soon as possible
     thereafter.

Prior to making any payments out of the Escrow Fund pursuant to subparagraph (c)
of this Section 4, the Escrow Agent shall provide written notice to the
Stockholders' Representative that it has received a Final Distribution
Certificate (a copy of which shall accompany such notice) from Buyer.

     5.   Disputed Claims.  If a controversy arises between one or more of the
          ---------------                                                     
parties hereto, as to whether or not or to whom the Escrow Agent shall deliver
the Escrow Fund or as to any other matter arising out of or relating to the
Escrow Fund or this Agreement, the Escrow Agent shall not be required to
determine the same and thereafter shall not make any delivery of the Escrow Fund
but shall retain it until the Escrow Agent shall have either (i) received
written instructions signed by both Buyer and the Stockholders' Representative
or (ii) been directed by an order of a court of competent jurisdiction as to the
respective rights of Buyer and the Stockholders' Representative with respect to
the Escrow Fund, in which case the Escrow Agent shall disburse the Escrow Fund
in accordance with such instructions or order within five (5) business days
after the receipt thereof, unless such instructions or order otherwise provide.
The Escrow Agent shall be entitled to assume that no such controversy has arisen
unless it has received a written notice that such a controversy has arisen which
refers specifically to this Agreement.  If a controversy of the type referred to
in this Section 5 arises, the Escrow Agent may, in its sole discretion (but
shall not be obligated to), commence interpleader or similar actions or
proceedings for determination of the controversy pursuant to Section 9.

     6.   Termination.  This Agreement shall terminate when all amounts of the
          -----------                                                         
Escrow Fund have been distributed.

                                       3
<PAGE>
 
     7.   Scope of Undertaking.  The Escrow Agent shall have no responsibility
          --------------------                                                
or obligation of any kind in connection with this Agreement and the Escrow Fund,
and shall not be required to deliver the same or any part thereof or take any
action with respect to any matters that might arise in connection therewith,
other than to receive, hold, and make delivery of the Escrow Fund as herein
expressly provided or by reason of a judgment or order of a court of competent
jurisdiction.

     8.   Knowledge and Sufficiency of Documents.  The Escrow Agent shall not be
          --------------------------------------                                
bound by or have any responsibility with respect to compliance with any
agreement between any of the other parties hereto, irrespective of whether the
Escrow Agent has knowledge of the existence of any such agreement or terms and
provisions thereof, the Escrow Agent's only duty, liability, and responsibility
being to receive, hold and deliver the Escrow Fund as herein provided.  The
Escrow Agent shall not be required in any way to determine the validity or
sufficiency, whether in form or in substance, of the Escrow Fund or the
validity, sufficiency, genuineness or accuracy of any instrument, document,
certificate, statement or notice referred to in this Agreement or contemplated
hereby (including, without limitation, wire transfer instructions, whether
incorporated herein or provided in a separate written instruction); or the
identity or authority of the persons executing the same, and it shall be
sufficient if any writing purporting to be such instrument, document,
certificate, statement or notice is delivered to the Escrow Agent and purports
on its face to be correct in form and signed or otherwise executed by the party
or parties required to sign or execute the same under this Agreement.

     9.   Right of Interpleader.  Should any controversy arise between Buyer, on
          ---------------------                                                 
one hand, and the Stockholders' Representative, on the other, or any other
person, firm or entity, with respect to this Agreement, the Escrow Fund, or any
part thereof, or the right of any party or other person to receive the Escrow
Fund, or should such parties fail to designate another Escrow Agent as provided
in Section 17 hereof, or if the Escrow Agent should be in doubt as to what
action to take, the Escrow Agent shall have the right (but not the obligation)
to (i) withhold delivery of the Escrow Fund until the controversy is resolved as
provided in Section 5 hereof, the conflicting demands are withdrawn or its doubt
is resolved as provided in Section 5 hereof, or (ii) institute a bill of
interpleader in any court of competent jurisdiction to determine the rights of
the parties hereto (the right of the Escrow Agent to institute such bill of
interpleader, however, shall not be deemed to modify the manner in which the
Escrow Agent is entitled to make disbursements of the Escrow Fund as hereinabove
set forth, other than to tender the Escrow Fund into the registry of such
court).  Should a bill of interpleader be instituted, or should the Escrow Agent
be threatened with litigation or become involved in litigation in any manner
whatsoever on account of this Agreement or the Escrow Fund, then as between
themselves and the Escrow Agent, Buyer and the Stockholders, jointly and
severally, hereby bind and obligate themselves, their successors, heirs,
executors and assigns to pay the Escrow Agent its reasonable attorneys' fees and
any and all other disbursements, expenses, losses, costs and damages of the
Escrow Agent in connection with or resulting from such threatened or actual
litigation.  Notwithstanding the foregoing, as between themselves, Buyer and the
Stockholders shall each pay one-half of all amounts payable to the Escrow Agent
pursuant to this paragraph.

     10.  Scope of Duties and Errors in Judgment.  It is expressly understood
          --------------------------------------                             
and agreed that the Escrow Agent shall be under no duty or obligation to give
any notice, or to do or to omit the doing of any action or anything with respect
to the Escrow Fund, except to hold the same (and any earnings thereon, pursuant
to the terms hereof) in the Escrow Account and to make disbursements in
accordance with the terms of this Agreement.  Without limiting the generality of
the foregoing, it is acknowledged and agreed that (i) no implied duties shall be
read into this Agreement on the part of the Escrow Agent, and (ii) the Escrow
Agent shall not be obligated to take any legal or remedial action which might in
its judgment involve it in any expense or liability for which it has not been
furnished acceptable indemnification.  The Escrow Agent, its directors, officers
and employees shall not be liable for any error in judgment or any act or steps
taken or permitted to be taken in good faith, or for any mistake of law or fact,
or for anything it may do or refrain from doing in connection herewith, except
for its own willful misconduct or gross negligence.

     11.  Indemnity.  As between themselves and the Escrow Agent, Buyer and the
          ---------                                                            
Stockholders, jointly and severally, agree to indemnify the Escrow Agent against
and hold the Escrow Agent harmless from any and all losses, costs, damages,
expenses, claims, and attorney's fees and expenses suffered or incurred by the
Escrow Agent as a result of, in connection with or arising from or out of the
acts or omissions of the Escrow Agent in performance of or pursuant to this
Agreement, except such acts or omissions as may result from the Escrow Agent's
willful misconduct or gross negligence.  In no event shall the Escrow Agent be
liable for indirect, punitive, special or consequential damages.

     Buyer and the Stockholders, jointly and severally, agree to indemnify and
hold the Escrow Agent harmless from and against any taxes, additions for late
payment, interest, penalties and other expenses, that may be assessed against
the Escrow Agent with respect to any payment of Escrow Funds or other activities
under this Agreement.  Buyer and Stockholders' Representative undertake to
instruct the Escrow Agent in writing with respect to the Escrow Agent's
responsibility for withholding and other taxes, assessments, or other
governmental charges, certifications and governmental reporting in connection
with its acting as Escrow Agent under this Agreement.  Buyer and the
Stockholders, jointly and severally, agree to indemnify and hold the Escrow
Agent harmless from any liability on account of taxes, assessments or other
governmental charges, including, without limitation, the withholding or
deduction or the failure to withhold or deduct the same, and any liability for
failure to obtain proper certifications or to properly report to governmental
authorities, to which the Escrow Agent may be or become subject in connection
with or which arises out of this Agreement, including costs and expenses
(including reasonable legal fees and expenses), interest and penalties.
Notwithstanding the foregoing, as between themselves, Buyer and the Stockholders
shall each pay one-half of all amounts payable to the Escrow Agent pursuant to
this paragraph. Notwithstanding any term hereof to the contrary, the terms of
this Section 11 shall survive the termination of this Agreement.

on one occasion shall not constitute a waiver of the other terms of this Escrow
