                     PLEDGE AGREEMENT AND IRREVOCABLE PROXY


     THIS PLEDGE AGREEMENT dated as of May 2, 1996 (this "Pledge Agreement"),
is given by AETNA INDUSTRIES, INC., a Michigan corporation (the "Company"), in
favor of NBD Bank, a Michigan banking corporation, as agent (in such capacity,
the "Agent") for the benefit of itself and the banks (the "Banks") now or
hereafter parties to the Credit Agreement described below.

                                    RECITALS

     A. The Company has entered into a Credit Agreement, dated as of even date
herewith, (as amended or modified from time to time, including any agreement
entered into in substitution therefor, the "Credit Agreement"), with the Banks
parties thereto and the Agent pursuant to which the Banks may make Advances (as
therein defined) to the Company.

     B. Under the Credit Agreement, the Company has agreed to pledge to the
Agent, for the benefit of the Banks, and grant a first-priority security
interest to the Agent, for the benefit of the Banks, in and to the collateral
described herein and to execute this Pledge Agreement.

     For value received and pursuant to the Credit Agreement, the Company
hereby grants a first-priority security interest to the Agent, for the benefit
of the Banks, in and to all of the outstanding capital stock of the companies
listed on the schedule attached hereto as Schedule A (the "Pledged
Subsidiaries", and said shares of stock, together with any other shares and
securities from time to time receivable or otherwise distributed in respect of
or in exchange for any or all of such shares, being called the "Pledged
Stock"), to secure, (a) the prompt and complete payment of all indebtedness and
other obligations of the Company or any Subsidiary now or hereafter owing to
the Banks or the Agent under or on account of the Credit Agreement, any
Security Document or any letters of credit, notes or other instruments issued
to the Agent or Banks pursuant thereto, (b) the performance of the covenants
under the Credit Agreement and the Security Documents and any monies expended
by the Agent in connection therewith, (c) the prompt and complete payment of
all obligations and performance of all covenants of the Company under any
hedging contract with any Bank and (d) the prompt and complete payment of any
and all other indebtedness, obligations and liabilities of any kind of the
Company or any Subsidiary to the Agent and the Banks, or any of them, in all
cases, of any kind or nature, howsoever created or evidenced and whether now or
hereafter existing, direct or indirect (including without limitation any
participation interest acquired by any Bank in any such indebtedness,
obligations or liabilities of the Company or any Subsidiary to any other
person), absolute or contingent, joint and/or several, secured or unsecured,
arising by operation of law or otherwise, and whether incurred by the Company
or any Subsidiary as principal, surety, endorser, guarantor, accommodation
party or otherwise, including without limitation all principal and all interest
(including any interest accruing subsequent to any petition filed by or against
the Company or any Subsidiary under the U.S. Bankruptcy Code), indemnity and
reimbursement obligations, charges, expenses, fees, attorneys' fees and
disbursements and any other amounts owing thereunder (all of the aforesaid
indebtedness, obligations and liabilities of the Company and its Subsidiaries
being herein called the "Secured Obligations", and all of the documents,
agreements and instruments among the Company, the Subsidiaries, the Agent, the
Banks, or any of them, evidencing or securing the repayment of, or otherwise
pertaining to, the Secured Obligations being herein collectively called the
"Operative Documents").  The Company is herewith delivering to the Agent for
the benefit of the Banks originals of all stock certificates of the Pledged
Stock or taking such other action

                     

   2
acceptable to the Agent and the Required Banks to perfect the security interest
in the Pledged Stock granted hereby.

     The Company further represents and warrants to, and agrees with, the Agent
for the benefit of the Banks as follows:

     1. Representations and Warranties.  The Company represents and warrants
that the Pledged Stock is represented by the stock certificate or certificates
or shares described on Schedule 1 hereto, and that such stock certificate or
certificates, accompanied by an instrument of assignment or transfer duly
executed in blank by the Company as the owner named in such stock certificate or
certificates, have been delivered to the Agent by the Company.  The Company
further represents and warrants that (a) the Pledged Stock is duly authorized
and validly issued, fully paid and nonassessable and constitutes 100% of all of
the issued and outstanding shares of the capital stock of each Pledged
Subsidiary, (b) the Company is the legal and beneficial owner of the Pledged
Stock, free and clear of all Liens other than the Lien of Agent hereunder, with
full right and power to deliver, pledge and assign the Pledged Stock to the
Agent hereunder, and (c) the pledge of the  Pledged Stock pursuant to this
Pledge Agreement creates in favor of the Agent a valid and perfected first
priority security interest in the Pledged Stock enforceable against the Company
and all third parties and securing the payment of the Secured Obligations.

     2. Title; Stock Rights, Dividends, Etc.  The Company will warrant and
defend the Agent's title to the Pledged Stock, and the security interest herein
created, against all claims of all persons, and will maintain and preserve such
security interest.  It is understood and agreed that the collateral hereunder
includes any stock rights, stock dividends, liquidating dividends, new
securities, payments, distributions and proceeds (including cash dividends and
sale proceeds) and other property to which the Company may become entitled by
reason of the ownership of the Pledged Stock during the existence of this Pledge
Agreement, and any such property received by the Company shall be held in trust
and forthwith delivered to the Agent to be held hereunder in accordance with the
terms of this Pledge Agreement.

     3. Registration Rights.  If any Pledged Subsidiary at any time or from time
to time proposes to register any of its securities under the Securities Act of
1933, the Company will at each such time give notice to the Agent of such
Pledged Subsidiary's intentions so to do.  Upon the request of the Agent given
30 days after receipt of such notice, the Company will cause all Pledged Stock
of such Pledged Subsidiary to be included in the registration statement proposed
to be filed, all to the extent requisite to permit the public sale or other
public disposition of such Pledged Stock so registered by the holders thereof.
The costs and expenses of all such registrations and qualifications under said
Act shall be paid by the Company or such Pledged Subsidiary, except that
underwriting discounts and commissions in respect of any Pledged Stock sold
pursuant to any such registration statement shall be borne by the sellers
thereof.  As expeditiously as possible after the effective date of any such
registration statement, the Company will deliver in exchange for any
certificates representing shares of Pledged Stock so registered pursuant to such
registration, which bear any restrictive legend, new Pledged Stock certificates
not bearing such legend or any similar legend.  In the event of any such
registration, the Company hereby agrees to indemnify and hold harmless the Agent
and the Banks as pledgee of the Pledged Stock against any losses, claims,
damages or liabilities to which the Agent and the Banks may become subject to
the extent that such losses, claims, damages or liabilities arise out of or are
based upon any untrue statement or alleged untrue statement of any material fact
contained in 

                   PLEDGE AGREEMENT AND IRREVOCABLE PROXY

   3


                   

any such registration statement, any preliminary prospectus or filed prospectus,
or in any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse the Agent and the Banks for any legal or other expenses
reasonably incurred by the Agent and the Banks in connection with investigating
or defending any such loss, claim, damage or liability.  The indemnifications
contained in this paragraph shall include each person, if any, who controls the
Agent or any Bank.

     4. Events of Default; Remedies.  (a) Upon the occurrence of any Event of
Default under the Credit Agreement, an Event of Default shall be deemed to have
occurred hereunder and the Agent shall have all of the rights and remedies
provided by law and/or by this Pledge Agreement, including but not limited to
all of the rights and remedies of a secured party under the Michigan Uniform
Commercial Code, and the Company hereby authorizes the Agent to sell all or any
part of the Pledged Stock at public or private sale and to apply the proceeds of
such sale to the costs and expenses thereof (including the reasonable attorneys'
fees and disbursements incurred by the Agent) and then to the payment of the
other Secured Obligations.  Any requirement of reasonable notice shall be met if
the Agent sends such notice to the Company, by registered or certified mail, at
least 5 days prior to the date of sale, disposition or other event giving rise
to the required notice.  The Agent or any Bank may be the purchaser at any such
sale.  The Company expressly authorizes such sale or sales of the Pledged Stock
in advance of and to the exclusion of any sale or sales of or other realization
upon any other collateral securing indebtedness or other obligations owed to the
Banks.  The Agent shall be under no obligation to preserve rights against prior
parties.

          (b) The Company hereby waives as to the Agent and the Banks any right
of subrogation or marshalling of such stock and other collateral for
indebtedness or other obligations owed to the Agent and the Banks.  To this end,
the Company hereby expressly agrees that any such collateral or other security
of the Company or any other party which the Agent or any Bank may hold, or which
may come to any of their possession, may be dealt with in all respects and
particulars as though this Pledge Agreement were not in existence.  The Company
agrees and acknowledges that because of applicable securities laws, the Agent
may not be able to effect a public sale of the Pledged Stock and sales at a
private sale may be on terms less favorable than if such securities were sold at
a public sale and may be at a price less favorable than a public sale.  The
Company agrees that all such private sales made under the foregoing
circumstances shall be deemed to have been made in a commercially reasonable
manner.

          (c) The Company irrevocably designates, makes, constitutes and
appoints the Agent (and all persons designated by the Agent) as its true and
lawful attorney (and agent-in-fact) and the Agent, or the Agent's agent, may,
upon and after an Event of Default hereunder which has not been waived, with
notice to the Company if the Secured Obligations have not been accelerated and
without notice if the Secured Obligations have been accelerated, take any action
as the Agent reasonably deems necessary under the circumstances to enforce or
otherwise take action in respect to the Pledged Stock as required hereby, or to
carry out any other obligation or duty of the Company under this Agreement. The
Company shall pay all reasonable fees and expenses, including reasonable
attorneys' fees and expenses, incurred by the Agent in connection with such
action.

   4



                    




     5. Additional Remedies; Irrevocable Proxy.  (a)  Upon the occurrence of any
Event of Default, the Agent shall have also the right to vote the Pledged Stock
on all questions after giving notice to the Company of its election to exercise
such rights.  In the absence of any such Event of Default, the Company shall
have the right to vote the Pledged Stock on all questions, provided that voting
by the Company of the Pledged Stock shall be in conformity with performance of
the obligations of the Company under the Operative Documents.

          (b) Whenever an Event of Default has occurred, the Agent may transfer
into its name, or into the name of its nominee or nominees, any or all of the
Pledged Stock and, as provided above, may vote any or all of the Pledged Stock
(whether or not so transferred) and may otherwise act with respect thereto as
though it were the outright owner thereof, the Company hereby irrevocably
constituting and appointing the Agent as the proxy and attorney-in-fact of the
Company, with full power of substitution, to do so.

          (c) In furtherance of the foregoing, it is acknowledged that the Agent
may vote the Pledged Stock to remove the directors and officers of any Pledged
Subsidiary, and to elect new directors and officers of any Pledged Subsidiary,
who thereafter shall manage the affairs of such Pledged Subsidiary, operate its
properties and carry on its business and otherwise take any action with respect
to the business, properties and affairs of such Pledged Subsidiary which such
new directors shall deem necessary or appropriate, including, but not limited
to, the maintenance, repair, renewal or alteration of any or all of the
properties of such Pledged Subsidiary, the leasing, subleasing, sale or other
disposition of any or all of such properties, the borrowing of money on the
credit of such Pledged Subsidiary, and the employment of attorneys, agents or
other employees deemed by such new directors to be necessary for the proper
operation, conduct, winding up or liquidation of the business, properties and
affairs of such Pledged Subsidiary, and all revenues from the operation,
conduct, winding up or liquidation of the business, properties and affairs of
such Pledged Subsidiary after the payment of expenses thereof shall be applied
to the payment of the Secured Obligations.

          (d) The Company agrees that the proxy granted in this paragraph 5 is
coupled with an interest and is and shall be both valid and irrevocable so long
as the Pledged Stock is subject to this Pledge Agreement.  The Company further
acknowledges that the term of said proxy may exceed three years from the date
hereof.

     6. Remedies Cumulative.  No right or remedy conferred upon or reserved to
the Agent and the Banks under any Operative Document is intended to be exclusive
of any other right or remedy, and every right and remedy shall be cumulative in
addition to every other right or remedy given hereunder or now or hereafter
existing under any applicable law.  Every right and remedy of the Agent and the
Banks under any Operative Document or under applicable law may be exercised from
time to time and as often as may be deemed expedient by the Agent and the Banks.
To the extent that it lawfully may, the Company agrees that it will not at any
time insist upon, plead, or in any manner whatever claim  or take any benefit or
advantage of any applicable present or future stay, extension or moratorium law,
which may affect observance or performance of any provisions of any Operative
Document; nor will it claim, take or insist upon any benefit or advantage of any
present or future law providing for the valuation or appraisal of any security
for its obligations under any Operative Document prior to any sale or sales
thereof which may be made under or

                                     - 4 -

   5
by virtue of any instrument governing the same; nor will it, after any such sale
or sales, claim or exercise any right, under any applicable law to redeem any
portion of such security so sold.

     7. Conduct No Waiver.  No waiver of default shall be effective unless in
writing executed by the Agent and waiver of any default or forbearance on the
part of the Agent in enforcing any of its rights under this Pledge Agreement
shall not operate as a waiver of any other default or of the same default on a
future occasion or of such right.

     8. Governing Law; Definitions.  This Pledge  Agreement is a contract made
under, and shall be governed by and construed in accordance with, the law of the
State of Michigan applicable to contracts made and to be performed entirely

serve process in any other manner permitted by law or limit the right of the
Agent to bring any such action or proceeding against the Company or its property
in the courts of any other jurisdiction.  The Company hereby irrevocably waives
any objection to the laying of venue of any such suit or proceeding in the above

provisions hereof.

     9. Notices.  All notices, demands, requests, consents and other
communications hereunder shall be delivered in the manner described in the

     10. Rights Not Construed as Duties.  The Agent neither assumes nor shall it
have any duty of performance or other responsibility under any contracts in
which the Agent has or obtains a security interest hereunder.  If the Company
fails to perform any agreement contained herein, the Agent may but is in no way
obligated to itself perform, or cause performance of, such agreement, and the
reasonable expenses of the Agent incurred in connection therewith shall be
payable by the Company under paragraph 13.  The powers conferred on the Agent

impose any duty upon it to exercise any such powers.  Except for the safe

     11. Amendments.  None of the terms and provisions of this Pledge Agreement
may be modified or amended in any way except by an instrument in writing
executed by each of the parties hereto.

     12. Severability.  If any one or more provisions of this Pledge Agreement
should be invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein shall

against any and all claims, losses and liabilities growing out of or resulting

Pledge Agreement), except claims, losses or liabilities resulting from the

          (b) The Company will, upon demand, pay to the Agent an amount of any

available funds of all of the Secured Obligations and the termination of all
commitments to lend under the Operative Documents, the security interest granted
hereunder shall terminate and upon such termination the Agent shall assign,
transfer and deliver without recourse and without warranty the Pledged Stock to
the Company (and any property received in respect thereof) as has not
theretofore been sold or otherwise applied pursuant to the provisions of this
Pledge Agreement.

     15. Waiver of Jury Trial.  The Agent and the Banks, in accepting this
Pledge Agreement, and the Company, after consulting or having had the
opportunity to consult with counsel, knowingly, voluntarily and intentionally
waive any right any of them may have to a trial by jury in any litigation based
upon or arising out of this Pledge Agreement or any related instrument or
agreement or any of the transactions contemplated by this Pledge Agreement or
any course of conduct, dealing, statements (whether oral or written) or actions
of any of them.  Neither the Agent, the Banks, nor the Company shall seek to
consolidate, by counterclaim or otherwise, any such action in which a jury trial
has been waived with any other action in which a jury trial cannot be or has not
been waived.  These provisions shall not be deemed to have been modified in any
respect or relinquished by either the Agent and the Banks or the Company except
by a written instrument executed by all of them.
