     2.4  Stockholders' Representative.
 
          (a) In order to administer efficiently (i) the implementation of the
Agreement by certain of the Stockholders, (ii) the waiver of any condition to
the obligations of such Stockholders to consummate the transactions     
contemplated hereby, and (iii) the settlement of any dispute with respect to    
this Agreement, the Former Management Stockholders and the Berkshire
Stockholders, with the exception of Berkshire and Berkshire Partners, (the
"Designating Stockholders") hereby designate Russell L. Epker as their
representative (the "Stockholders' Representative").
 
          (b) The Designating Stockholders hereby authorize the Stockholders'
Representative (i) to take all action necessary in connection with the
implementation of the Agreement on behalf of the Designating Stockholders, the
waiver of any condition to the obligations of the Designating   Stockholders to
consummate the transactions contemplated 




                                      3

   7
hereby, and the settlement of any dispute, (ii) to give and receive all notices
required to be given under the Agreement with respect to the Designating
Stockholders and (iii) to take any and  all additional action as is contemplated
to be taken by or on behalf of the Designating Stockholders by the terms of this
Agreement, including without limitation, the execution and delivery of documents
to transfer the Stock Purchase Shares to Buyer.
 
          (c) Each Designating Stockholder hereby specifically authorizes and
directs the Stockholders' Representative to execute on behalf of such
Designating Stockholder the certificates to be delivered to Buyer by the        
Company and the Stockholders pursuant to Section 7.3(b) unless such
authorization and direction shall have been revoked in writing by such
Designating Stockholder prior to the Stock Purchase Closing.
 
          (d) In the event that the Stockholders' Representative dies, becomes
legally incapacitated or resigns from such position, Robert J. Small shall fill
such vacancy and shall be deemed to be the Stockholders' Representative
for all purposes of this Agreement unless otherwise determined by the
Designating Stockholders owning a majority of the shares of New Stock held (on a
fully diluted basis) by all Designating Stockholders; however, no change in the
Stockholders' Representative shall be effective until Buyer is given notice of
it by one or more of the Designating Stockholders.
 
          (e) All decisions and actions by the Stockholders' Representative in
accordance with this Agreement shall be binding upon all of the Designating     
Stockholders, and no Designating Stockholder shall have the right to object,
dissent, protest or otherwise contest the same.
 
          (f) By their execution of this Agreement, the Designating Stockholders
agree that:
 
              (i) Buyer shall be able to rely conclusively on the instructions
        and decisions of the Stockholders' Representative as to any actions
        required or permitted to be taken by the Designating Stockholders or the
        Stockholders' Representative hereunder, and no party hereunder shall
        have any cause of action against Buyer for any action taken by Buyer in
        reliance upon the instructions or decisions of the Stockholders'
        Representative;
 
             (ii) all actions, decisions and instructions of the Stockholders'
        Representative shall be conclusive and binding upon all of the
        Designating Stockholders and no Designating Stockholder shall have any
        cause of action against the Stockholders' Representative for any action
        taken, decision made or instruction given by the Stockholders'
        Representative under this Agreement, except for fraud or willful breach
        of this Agreement by the Stockholders' Representative;
 
             (iii) remedies available at law for any breach of the provisions of
        this Section 2.4 are inadequate; therefore, Buyer shall be entitled to
        temporary and




                                      4


   8

        permanent injunctive relief without the necessity of proving damages
        if Buyer brings an action to enforce the provisions of this Section 2.4;
        and
 
             (iv) the provisions of this Section 2.4 are independent and
        severable, shall constitute an irrevocable power of attorney, coupled
        with an interest and surviving death, granted by the Designating
        Stockholders to the Stockholders' Representative and shall be binding
        upon the executors, heirs, legal representatives and successors of each
        Designating Stockholder.
 
          (g) All fees and expenses incurred by the Stockholders' Representative
shall be paid pro rata by the Designating Stockholders in accordance with their
ownership of New Common Stock.
 
SECTION 3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY TO BUYER.
 
     3.1 Making of Representations and Warranties. As a material inducement to
Buyer to enter into this Agreement and consummate the Recapitalization and Stock
Purchase contemplated hereby, the Company hereby makes to Buyer, except as set
forth on a disclosure schedule (the "Recapitalization and Stock Purchase
Disclosure Schedule") with respect to the representations and warranties in
Section 3.3 (to be delivered to Buyer prior to the Stock Purchase Closing), the
representations and warranties contained in this Section 3.
 
     3.2 Organization of the Company. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. Aetna Industries, Inc. ("Aetna") is a corporation duly organized,
validly existing and in good standing under the laws of the State of Michigan.
Aetna Export Sales Corp. ("Export") is a corporation duly organized, validly
existing and in good standing under the laws of the United States Virgin
Islands. Aetna and Export are the only subsidiaries of the Company. The Company
and each of its subsidiaries have the requisite corporate power and authority to
own, lease and operate their properties and to conduct their businesses as
currently conducted. Each of the Company and its subsidiaries is duly qualified
as a foreign corporation to do business in each jurisdiction where the character
of the properties owned, leased or operated by it or the nature of its business
makes such qualification necessary, except where the failure to be so qualified
would not have a Company Material Adverse Effect (as defined below). The term
"Company Material Adverse Effect" means any change or effect that is or would be
materially adverse to the business, assets, results of operations or financial
condition of the Company and its subsidiaries taken as a whole. Except for its
ownership of the subsidiaries, the Company does not directly or indirectly own
any equity or similar interest in, or any interest convertible, exchangeable or
exercisable for or into, any equity or similar interest in any person.
 




                                      5

     3.3  Capital Stock of the Company. The authorized capital stock of the
Company consists solely of (i) 1,040,000 shares of Old Class A Common Stock,
(ii) 1,040,000 shares of Old Class B Common Stock, (iii) 80,168 shares of Old
Series A Preferred Stock, and (iv) 250,000 shares of Old Series B Preferred
Stock. As of the date hereof, there are no other shares of capital stock
outstanding or reserved for issuance except pursuant to the Company's Executive
Stock Option Plan, as amended. Upon the Recapitalization Closing, the authorized
capital stock of the Company will consist solely of (i) 5,000,000 shares of New
Class A Common Stock, (ii) 5,000,000 shares of New Class B Common Stock, (iii)
293,123.320 shares of New Series A Preferred Stock and (iv) 2,000,000 shares of
a class of preferred stock, $.01 par value per share. Following the
Recapitalization, all of the outstanding shares of New Stock will (i) have been
duly authorized, validly issued and fully paid and will be non-assessable free
and clear of all Liens and (ii) be the only issued and outstanding capital stock
of the Company. The Company owns all of the outstanding shares of capital stock
of Aetna (consisting of 1,000 shares of common stock) and Aetna owns all of the
outstanding shares of capital stock of Export (consisting of 1,000 shares of
common stock), and all such shares are duly authorized, validly issued, fully
paid and non-assessable, and free and clear of all preemptive rights and all
Liens. There are no agreements or understandings to which the Company or any
subsidiary of the Company is a party with respect to the voting of, or other
interest in, any shares of Old Stock or New Stock or which restricts the
transfer of any such shares. There are no outstanding contractual obligations of
the Company or any subsidiary of the Company to repurchase, redeem or otherwise
acquire any shares of capital stock or Option of the Company or any subsidiary
of the Company, or to make any investment in any subsidiary or any other person.
 
     3.4  Authority of the Company. The Company has full right, authority and
power to enter into this Agreement and each agreement, document and instrument
to be executed and delivered by the Company pursuant to this Agreement and to
carry out the transactions contemplated hereby and thereby. The execution,
delivery and performance by the Company of this Agreement and each such other
agreement, document and instrument have been duly authorized by all necessary
action of the Company and no other corporate action on the part of the Company
is required in connection therewith. This Agreement and each agreement, document
and instrument executed and delivered by the Company pursuant to this Agreement
constitutes, or when executed and delivered will constitute, valid and binding
obligations of the Company enforceable against the Company in accordance with
their terms. The execution, delivery and performance of this Agreement and each
such agreement, document and instrument does not and will not violate any
provision of the organizational documents of the Company or any laws of the
United States or any state or other jurisdiction applicable to the Company, or,
except for agreements which will be terminated at the closing of the
transactions contemplated by the Aetna Holdings Agreement, require the
Company to obtain any approval, consent or waiver from, or make any filing with,
any person or entity (governmental or otherwise) that has not been obtained or
made or will not be obtained or made prior to the Recapitalization Closing.
