Merkert American Corporation, a Delaware corporation ("Merkert") each of MS

         Richmont Marketing Specialists Inc., a Delaware corporation (the
"Company"), Merkert and the Holders, propose to enter into an Agreement and Plan
of Merger dated as of April 28, 1999 (the "Merger Agreement"), pursuant to which
the Company would be merged with and into Merkert (the "Merger"), and each
outstanding share of capital stock of the Company would be converted into shares
of common stock, par value $.01 per share, of Merkert ("Merkert Common Stock");

         As a condition of its entering into the Merger Agreement, Merkert has
requested the Holders to agree, and the Holders have agreed, to enter into this
Agreement; and

         NOW, THEREFORE, the parties hereto agree as follows:

         1. Representations and Warranties of the Holders. Each Holder
represents and warrants to Merkert as follows:

                  (a) Ownership of Securities. The Holder is the record and
(except, in the case of Mr. Butler and Mr. Guffey, for any interest of the
spouses of such Holders arising under applicable community property laws)
beneficial owner of the number of shares of Company Capital Stock set forth on
the signature page to this Agreement (the "Existing Securities," and, together
with any shares of Company Capital Stock or other securities of the Company
hereafter acquired by the Holder, the "Subject Securities"). Other than as
disclosed in the RMSI Disclosure Letter (as such term is defined in the Merger
Agreement), the Holder does not own any capital stock or other securities of the
Company (including any options, warrants, rights, commitments, preemptive right
or agreements of any kind for the issuance or sale of, or outstanding securities
convertible into any shares of capital stock, of any class, of the Company, or
outstanding warrants, options or other rights to acquire any such convertible
securities or stock appreciation rights or other instrument whose value is
derived from the Company Capital Stock) on the date of this Agreement other than
the Existing Securities. The Holder has sole voting power and sole power to
issue instructions with respect to the voting of the Existing Securities, sole
power of disposition, sole power of exercise or conversion and the sole power to
demand appraisal rights, in each case with respect to all of the Existing
Securities. On the date of the special meeting of stockholders of the Company

have sole voting power and sole power to issue instructions with respect to the
voting of all of the Subject Securities, sole power of disposition, sole power
of exercise or conversion and the sole power to demand appraisal rights, in each
case with respect to all of the Subject Securities.

                  (b) Power; Binding Agreement. The Holder has full power and
authority to enter into and perform all of the Holder's obligations under this
Agreement. If Holder is an entity, the execution by Holder of this Agreement and
the performance of its obligations hereunder have been duly authorized by all
necessary corporate or partnership action on the part of Holder and no other
action on the part of Holder is required in connection therewith. This Agreement
has been duly and validly executed and delivered by the Holder and constitutes a
valid and binding agreement of the Holder, enforceable against the Holder in
accordance with its terms.

                  (c) No Conflicts. No filing with, and no permit,
authorization, consent or approval of, any state or federal public body or
authority is necessary for the execution of this Agreement by the Holder and the
consummation by the Holder of the transactions contemplated hereby and neither
the execution and delivery of this Agreement by the Holder nor the consummation
by the Holder of the transactions contemplated hereby nor compliance by the
Holder with any of the provisions hereof shall conflict with or result in any
breach of any applicable organizational documents of the Company applicable to
the Holder or, if applicable, any organizational documents of the Holder
(including without limitation any charter documents or partnership agreement),
result in a violation or breach of, or constitute (with or without notice or
lapse of time or both) a default (or give rise to any third-party right of
termination, cancellation, material modification or acceleration) under any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
license, contract, commitment, arrangement, understanding, agreement or other
instrument or obligation of any kind to which the Holder is a party or by which
the Holder's properties or assets may be bound or violate any order, writ,
injunction, decree, judgment, order, statute, rule or regulation applicable to
the Holder or any of the Holder's properties or assets. The Holder expressly
waives any rights or conflicts under the Stockholders Agreement by and among the
Holders and Marketing Specialists Sales Corporation dated as of October 7, 1997
which may arise by the execution of this Agreement by the Holder or any other
stockholder of the Company and hereby acknowledges and consents in all respects
to the execution of this Agreement by all such stockholders.

                  (d) No Liens. The Existing Securities are now and, at all
times during the term hereof, the Subject Securities will be held by the Holder,
or by a nominee or custodian for the benefit of such Holder, free and clear of
all liens, claims, security interests, proxies, voting trusts or agreements,
understandings or arrangements or any other encumbrances whatsoever, except for

the Company called with respect to any of the following, and at every
postponement or adjournment thereof, and on every action or approval by written
consent of the stockholders of the Company with respect to any of the following,
each Holder agrees that it shall vote all of the Subject Securities that it owns

the majority of the board of directors of the Company or any of its

Company or any of its subsidiaries or any amendment of the Certificate of
Incorporation or similar governing document of the Company or any of its
subsidiaries; (c) any other material change in the corporate structure or
business of the Company or any of its subsidiaries; or (d) any other action,
which, in the case of each of the matters referred to in clauses (a), (b), (c)
or (d) above, is intended, or could reasonably be expected, to impede, interfere
with, delay, postpone, discourage or materially adversely affect the
contemplated economic benefits to Merkert of the Merger or the transactions
contemplated by the Merger Agreement or this Agreement.

         3. IRREVOCABLE PROXY. EACH OF THE HOLDERS HEREBY GRANTS TO, AND
APPOINTS MERKERT AND THE CHIEF EXECUTIVE OFFICER OF MERKERT AND THE CHIEF
FINANCIAL OFFICER OF MERKERT, IN THEIR RESPECTIVE CAPACITIES AS OFFICERS OF
MERKERT, AND ANY INDIVIDUAL WHO SHALL HEREAFTER SUCCEED TO ANY SUCH OFFICE OF

SUCH OTHER INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS
PROXY AND HEREBY REVOKES ANY PROXY PREVIOUSLY GRANTED BY IT WITH RESPECT TO THE
SUBJECT SECURITIES.

therewith. This Agreement has been duly and validly executed and delivered by
Merkert and constitutes a valid and binding agreement of Merkert, enforceable
against Merkert in accordance with its terms.

                  (b) No Conflicts. No filing with, and no permit,
