EXPECTS TO COMPLETE THE ACQUISITION OF SUBSTANTIALLY ALL OF THE ASSETS OF
AUTOMOTIVE PRODUCTS COMPANY ("APC"), A DIVISION OF A.O. SMITH CORPORATION ("A.O.
SMITH"), BY THE END OF APRIL 1997. SUCH ACQUISITIONS ARE REFERRED TO HEREIN AS

RESPECTIVELY. UNLESS OTHERWISE INDICATED, FINANCIAL AND OPERATING DATA PRESENTED

PRO FORMA FINANCIAL STATEMENTS."
 
                                  THE COMPANY
 
GENERAL
 
   
    The Company is a leading designer and producer of high-quality body
structure components and assemblies used by the major North American automotive
original equipment manufacturers ("OEMs"), Ford, Chrysler and General Motors,
and certain foreign OEMs with manufacturing operations in North America
("Transplants"), including Honda, Toyota, Nissan and Mazda. The Company's
current products range from large structural stampings and assemblies, such as
body pillars, chassis, suspension and floor pan components and major housing
assemblies, to engineered assemblies, such as hood and deck lid hinges and brake
components. On January 27, 1997, the Company agreed to acquire A.O. Smith's APC
division, a leading manufacturer of light truck frames, automotive engine
cradles and other structural and suspension components, assemblies and modules
used by major North American OEMs and Transplants. Following the APC
Acquisition, the Company believes it will be one of the largest independent
suppliers of structural components and assemblies to the North American
automotive market (based on net sales).
    
 
   
    Since its inception in April 1993, the Company's revenues have grown rapidly
through a focused strategy of internal growth and a highly disciplined
acquisition program. During the last three years, the Company has successfully
completed and fully integrated four acquisitions. As a result of such
acquisitions and internal growth, the Company's revenues have increased from
approximately $86 million in 1993 to approximately $474 million in 1996 (pro
forma only for the MSTI Acquisition), representing a compound annual growth rate
of approximately 76%. The Company's North American content per vehicle has
increased from $6.23 in 1993 to $26.74 in 1996 on an actual basis. The APC
Acquisition will be the Company's largest acquisition to date and will increase
the Company's pro forma revenues to approximately $1.3 billion and its pro forma
North American content per vehicle to $77.49 for 1996.
    
 
    The Company operates in the large and highly fragmented structural segment
of the automotive supply industry, which has recently begun to undergo
significant consolidation. To lower costs and improve quality, OEMs are reducing
their supplier base by awarding sole-source contracts to full-service suppliers
who are able to supply larger portions of a vehicle on a global basis. OEMs'
criteria for supplier selection include not only cost, quality and
responsiveness, but also full-service design, engineering and program management
capabilities. OEMs are increasingly seeking suppliers capable of providing
complete systems or modules rather than suppliers who only provide separate
component parts. In addition, OEMs are increasingly requiring their suppliers to
have the capability to design and manufacture their products in multiple
geographic markets. As a full-service supplier with strong OEM relationships,
the Company expects to continue to benefit from these trends within the
structural segment of the automotive supply industry.
 
                                       3
<PAGE>
   
    The Company's business objective is to capitalize on the consolidation,
globalization and system/ modular sourcing trends in the automotive supply
industry in order to be the leading provider of structural and suspension
components to OEMs worldwide. The Company's growth strategy focuses on the
identification and pursuit of (i) strategic acquisitions; (ii) modular product
opportunities; (iii) increased vehicle penetration; and (iv) "world car"
opportunities.
    
 
THE APC ACQUISITION
 
    APC is a leading designer and producer of structural and suspension
components for the automotive, light truck and heavy truck markets. APC's
products include light truck frames, automotive engine cradles, suspension and
other components and heavy truck frame rails. In 1996, over 70% of APC's
revenues was derived from the sale of structural components for light trucks and
sport utility vehicles, a growing segment of the North American automotive
market. APC's customers include the three major North American OEMs as well as
certain Transplants, including Toyota, Nissan, Isuzu and Honda. APC's three
largest customers, Ford, General Motors and Chrysler, accounted for
approximately 46%, 23% and 20%, respectively, of APC's revenues in 1996.
Approximately 11% of APC's revenues in 1996 was derived from the production of
heavy truck frame rails for North American heavy truck OEMs. The Company
believes APC is the largest supplier in this segment, with a market share of
approximately 51% in 1996. APC conducts its operations through 15 facilities
which, when added to the Company's existing 19 facilities, will result in a
total of over seven million square feet of manufacturing floor space.
 
    The Company believes that the APC Acquisition will provide the Company with
several strategic
benefits, including the following:
 
   
    EXPANDED PRODUCT OFFERINGS AND MODULAR PRODUCT OPPORTUNITIES.  The APC
Acquisition will significantly expand the Company's product offerings by adding
lower body structural components to the Company's existing line of upper body
structural components. In addition, APC's products provide an ideal platform for
developing modular product offerings for the Company's customers. APC's frame
and engine cradle products can be combined with a number of the Company's
existing product offerings, including control arms, suspension components,
exhaust hanger assemblies and spring towers and hangers to deliver more complete
systems or modules to its OEM customers at a lower overall cost. The APC
Acquisition will enable the Company to produce a larger portion of a vehicle,
which the Company believes will afford it significant opportunities to increase
revenues as OEMs continue to consolidate their supplier base. See
"Business--Industry Trends."
    
 
    INCREASED CUSTOMER PENETRATION.  The APC Acquisition will significantly
expand the Company's penetration within each of the three major North American
OEMs. Following the APC Acquisition, the Company believes it will be the largest
supplier of structural components to Chrysler, the largest supplier of metal
components to Ford and a major supplier of structural components to General
Motors. The APC Acquisition will also expand the Company's penetration within
certain Transplants by doubling the Company's sales to Toyota, expanding its
already significant position at Honda, increasing sales to Nissan and adding
Isuzu as a new customer.
 
   
    INCREASED PENETRATION IN LIGHT TRUCK SEGMENT AND OTHER KEY MODELS.  The APC
Acquisition will increase the Company's North American content per vehicle from
$26.74 in 1996 to $77.49 on a pro forma basis and will triple the Company's
content per vehicle in the expanding light truck/sport utility market segment,
which segment represented approximately 60% of the Company's pro forma revenues
for 1996. The APC Acquisition will increase the Company's content per vehicle on
key light truck/sport utility vehicles such as the Ford Explorer and Ranger and
the Chrysler Dakota, Durango and Ram as well as on high volume passenger cars
such as the Ford Taurus/Sable and the Chrysler Intrepid/Concorde/Vision. The
Company believes that this increased model penetration will afford it greater
opportunities to supply additional parts and modules for such models.
    
 
                                       4
<PAGE>
    COMPLEMENTARY NEW TECHNOLOGY.  The APC Acquisition will provide the Company
with a variety of new and enhanced design and manufacturing technology,
including APC's patented three piece side rail frame and patented Simulform-TM-
forming technology, the latter of which may result in cost savings and quality
improvements over conventional stamping technology in certain specialized
applications. In addition, APC's existing hydroforming technology complements
the Company's initiatives in this area. The APC Acquisition will also provide
the Company with additional painting, coating and welding technologies and
advanced logistical parts management systems. The Company believes that these
acquired technologies will provide significant additional opportunities to serve
existing customers and obtain new business.
 
   
    OPERATIONAL EFFICIENCIES.  The APC Acquisition will provide the Company with
a number of opportunities to reduce costs and improve operational efficiency.
For example, APC currently outsources many of its stamping needs, some of which
will be able to be supplied by the Company's existing stamping facilities. In
addition, the Company's and APC's facilities are geographically located in such
a way as to allow the Company to optimize its management and logistical
capabilities on a regional basis. APC's facilities are strategically located
close to many of its and the Company's major customers, allowing for inventory
and freight cost-savings. The increased size of the Company may also improve the
Company's ability to negotiate more favorable terms on its purchasing and supply
contracts, as well as achieve other operational cost savings.
    
 
    EXPANDED GLOBAL CAPABILITIES.  OEMs are increasingly demanding that their
suppliers have global production capabilities. APC's presence in China, Japan
and South America complements the Company's current European initiatives to
provide expanded global production capabilities for both North American and
international OEMs. See "Business--Global Initiatives."
 
   
    The aggregate purchase price of APC is approximately $625 million, plus an
additional $25 million for related fees and expenses and management's estimate
of certain post-closing adjustments. The Company expects to complete the APC
Acquisition by the end of April 1997. Pursuant to the terms of the purchase
agreement, the Company may elect not to complete the APC Acquisition if there is
a material adverse change in the operating results or financial condition of APC
prior to the closing date. Currently, the Company believes that such a change
has not occurred and that it is unlikely that such a change will occur prior to
the closing date. If the APC Acquisition is not completed, the shares of Common
Stock offered hereby would represent an ownership interest in the Company as it
exists on the date hereof and not of the Company as combined with APC. In such
an event, the net proceeds of the Offering will be used for general corporate
purposes, which may include repayment of existing indebtedness, acquisitions or
capital expenditures. See "Risk Factors--Risks Associated with the Failure to
Complete the APC Acquisition."

- --------------------------
 
(1) Includes the results of operations of MSTI from the date of acquisition, May
    31, 1996.
 
(2) The unaudited pro forma as adjusted statement of operations data reflect:
    (i) the MSTI Acquisition (including related financing transactions); (ii)
    the APC Acquisition; (iii) the sale by the Company of 2,232,900 shares of
    Common Stock in June 1996 (the "1996 Offering") and the application of the
    proceeds therefrom; (iv) the refinancing of the Company's existing credit
    agreement (the "Existing Credit Agreement") and the redemption of the
    Company's senior notes (the "Senior Notes") in connection with the APC
    Acquisition; and (v) the Offering and the application of the net proceeds to
    the Company as described in "Use of Proceeds," as if such transactions had
    occurred on January 1, 1996. The Company acquired Trylon on January 16,
    1996. Results of operations of Trylon for the period January 1, 1996 through
    the acquisition date are not material and therefore have not been included
    in the Company's pro forma results of operations for the year ended December
    31, 1996. See "Use of Proceeds" and "Unaudited Pro Forma Financial
    Statements." Net income, net income applicable to common stockholders and
    net income per common and common equivalent share are presented before
    extraordinary loss on early extinguishment of debt.
 
   
(3) The Company has not declared or paid any cash dividends on its Common Stock
    in the past, currently intends to retain its earnings to support its growth
    strategy and does not anticipate paying dividends in the foreseeable future.
    See "Dividend Policy."

(4) "EBITDA" is operating income plus depreciation and amortization. EBITDA does
    not represent and should not be considered as an alternative to net income
    or cash flow from operations as determined by generally accepted accounting
    principles ("GAAP") and the Company's calculation thereof may not be
    comparable to that reported by other companies. The Company believes that it
    is widely accepted that EBITDA provides useful information regarding a
    company's ability to service and/or incur indebtedness. This belief is based
    on the Company's negotiations with its lenders who have indicated that the
    amount of indebtedness the Company will be permitted to incur will be based,
    in part, on the Company's EBITDA. EBITDA does not take into account the
    Company's working capital requirements, debt service requirements and other
    commitments and, accordingly, is not necessarily indicative of amounts that
    may be available for discretionary uses. Set forth below is a reconciliation
    of the Company's operating income, as reported, to EBITDA for the periods
    indicated:

    comprised of car and light truck production in the United States, Canada and
    Mexico, as estimated by the Company from industry sources. Pro forma as

FACTORS, SOME OF WHICH MAY BE BEYOND THE CONTROL OF THE COMPANY. THE COMPANY
CAUTIONS THE READER, HOWEVER, THAT THIS LIST OF FACTORS MAY NOT BE EXHAUSTIVE,
PARTICULARLY WITH RESPECT TO FUTURE FILINGS WITH THE COMMISSION. IN ANALYZING AN
INVESTMENT IN THE COMMON STOCK OFFERED HEREBY, PROSPECTIVE INVESTORS SHOULD
CAREFULLY CONSIDER, ALONG WITH THE OTHER MATTERS REFERRED TO HEREIN, THE RISK
FACTORS DESCRIBED BELOW.
 
   
RISKS ASSOCIATED WITH THE FAILURE TO COMPLETE THE APC ACQUISITION
    
 
   
    The Company expects to complete the APC Acquisition by the end of April
1997. Pursuant to the terms of the purchase agreement, the Company may elect not
to complete the APC Acquisition if there is a material adverse change in the
operating results or financial condition of APC prior to the closing date. There
can be no assurance that such a change will not occur or that, if such a change
were to occur, that the APC Acquisition would be completed. If the APC
Acquisition is not completed, the shares of Common Stock offered hereby would
represent an ownership interest in the Company as it exists on the date hereof
and not of the Company as combined with APC. Therefore, if the APC Acquisition
is not consummated, the information set forth in this Prospectus giving effect
to the APC Acquisition would not be relevant.
    
 
   
    Prior to the Offering, there were 14,340,800 shares of Common Stock
outstanding. Upon consummation of the Offering, there will be 22,840,800 shares
of Common Stock outstanding. If the APC Acquisition is not consummated, the size
of the Company will not increase, but the number of outstanding shares will
have, and thus the value of each share of the Common Stock would be
significantly diluted. The Company's net income per common and common equivalent
share before extraordinary item ("EPS") for 1996 on a pro forma as adjusted
basis would have been $2.25 per share. If the APC Acquisition is not completed,
the Company's EPS for 1996 on a pro forma as adjusted basis would have been
$1.17 per share. In addition, the net proceeds to the Company from the Offering
are expected to be used to pay a portion of the cash purchase price of the APC
Acquisition. In the event the APC Acquisition is not consummated, the Company
intends to use the net proceeds of the Offering for general corporate purposes,
which may include repayment of existing indebtedness, acquisitions or capital
expenditures.
    
 
   
    In connection with the APC Acquisition, the Company expects to enter into a
new credit agreement (the "New Credit Agreement") to finance a portion of the
APC Acquisition. The commitments of its bank lender under the New Credit
Agreement expire if the APC Acquisition is not consummated on or prior to April
30, 1997. If such commitments expire and are not renewed by such lender, the
Company would be required to seek alternative sources of financing. There can be
no assurance that the Company would be able to secure such alternative financing
or that such financing, if available, would be on terms acceptable to the
Company. If the Company does not consummate the APC Acquisition because it fails
to secure financing, the Company is required to pay A.O. Smith a fee of $15.0
million. In addition, if the APC Acquisition is not consummated by June 30,
1997, A.O. Smith's obligation to consummate the APC Acquisition will lapse and
there can be no assurance that the Company will be able to purchase APC on the
terms disclosed herein, on terms acceptable to the Company or at all.

<PAGE>
RISKS ASSOCIATED WITH LEVERAGE
 
   
    The APC Acquisition will significantly increase the Company's debt service
obligations. As of December 31, 1996 on a pro forma basis, the Company would
have had total outstanding long-term indebtedness of approximately $405.8
million, or 44.8% of the Company's total capitalization. The degree to which the
Company is leveraged could make it more difficult for the Company to adjust to
rapidly changing market conditions and could make it more vulnerable in the
event of a downturn in general economic conditions or its business. See
"Description of New Credit Agreement."
    
 
RELIANCE ON MAJOR CUSTOMERS AND SELECTED MODELS
 
   
    Ford, Chrysler and General Motors accounted for approximately 67%, 10% and
4%, respectively, of the Company's revenues during 1996 and approximately 53%,
17% and 17%, respectively, on a pro forma basis. Although the Company and APC
have contracts with many of their customers, such contracts provide for
supplying the customers' requirements for a particular model, rather than for
manufacturing a specific quantity of products. The loss of any one of their
major customers or a significant decrease in demand for certain key models or a
group of related models sold by any of their major customers could have a
material adverse effect on the Company and APC. There is substantial and
continuing pressure from OEMs to reduce costs, including the cost of products
purchased from outside suppliers such as the Company and APC. Certain of the
Company's products are sold under long-term agreements that require the Company
to provide annual cost reductions to such purchasers (directly through price
reductions or indirectly through suggestions regarding manufacturing
efficiencies or other cost savings) by certain percentages each year. Although
the Company has been able to achieve a portion of such reductions through
production cost savings, there can be no assurance that the Company will be able
to continue to generate such cost savings in the future. If the Company were
unable to generate sufficient production cost savings in the future to offset
such price reductions, the Company's gross margin could be adversely affected.
See "Business--Customers and Marketing."
    
 
   
RISKS RELATED TO INDUSTRY CYCLICALITY AND SEASONALITY
    
 
    The automotive market is highly cyclical and is dependent on consumer
spending. Economic factors adversely affecting automotive production and
consumer spending could adversely impact the Company. In addition, the Company's
business is somewhat seasonal. The Company typically experiences decreased
revenue and operating income during the third quarter of each year due to the
impact of OEM plant shutdowns in July for vacations and model changeovers. The
Company expects such seasonality to continue following the APC Acquisition. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition--Seasonality."
 
FAILURE TO REALIZE BENEFITS OF APC ACQUISITION
 
    The Company believes the APC Acquisition will significantly enhance its
competitive position and business prospects. There can be no assurance, however,
that such benefits will be realized or that the combination of the Company and
APC will be successful. In addition, the Company expects to achieve cost savings
through the integration of the operations of APC with those of the Company.
There can be no assurance that the Company will not experience difficulties in
integrating the operations of APC with those of the Company or that the expected
cost savings will be realized. The integration of APC will require the
experience and expertise of certain key managers of APC who are expected to be
retained by the Company. There can be no assurance that the APC managers
retained by the Company will remain with the Company for the time period
necessary to successfully integrate APC into the Company.

RISKS ASSOCIATED WITH OBTAINING BUSINESS FOR NEW AND REDESIGNED MODEL
  INTRODUCTIONS
    
 
   
    The Company and APC principally compete for new business both at the
beginning of the development of new models and upon the redesign of existing
models by their major customers. New model development generally begins two to
five years prior to the marketing of such models to the public. There can be no
assurance that the Company and APC will be successful in obtaining significant
new business on new models and in supplying additional parts for existing models
as they are redesigned by their customers. The failure of the Company and APC to
obtain new business on new models or to retain or increase business on
redesigned existing models could adversely affect the Company. See "Business--
Competition."
    
 
RISKS ASSOCIATED WITH ACQUISITION STRATEGY
 
   
    Acquiring businesses that complement the Company's existing business has
been and will continue to be an important element of the Company's strategy for
achieving profitable growth. There can be no assurance that suitable acquisition
candidates will be identified and acquired in the future, that financing for any
such acquisitions will be available on satisfactory terms, that the Company will
be able to accomplish its strategic objectives as a result of any such
acquisition or that any business or assets acquired by the Company will be
integrated successfully into the Company's operations. The Company is
continually evaluating possible acquisitions and engages in discussions with
acquisition candidates from time to time. The Company does not currently have
any pending acquisitions that are probable other than as described herein. See
"Business--Strategy."
    
 
   
RISKS FROM COMPETITION
    
 
   
    The automotive components supply industry is highly competitive. Some of the
competitors of the Company and APC, including certain divisions of its OEM
customers, are larger and have greater financial and other resources than the
Company and APC. There can be no assurance that the Company will be able to
maintain its current competitive position and continue to supply its products to
OEMs. See "Business-- Competition."
    
 
   
ANTI-TAKEOVER PROVISIONS COULD PREVENT OR DELAY A CHANGE IN CONTROL
    
 
    Certain provisions of the Company's Amended and Restated Certificate of
Incorporation, which permit the Board of Directors to issue up to 5,000,000
shares of preferred stock without further stockholder approval, as well as
certain provisions of the Delaware General Corporation Law, could have the
effect of delaying, deterring or preventing a change in control of the Company.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
    The public offering price per share of the Common Stock has been determined
by negotiations among the Company and representatives of the Underwriters based
in part on the trading price of the Common Stock on the NYSE and may not be
indicative of the price at which the Common Stock will trade after completion of
the Offering. In addition, the stock markets have from time to time experienced
extreme price and volume volatility. These fluctuations may be unrelated to the
operating performance of particular companies whose shares are traded. Market
fluctuations may adversely affect the market price of the Common Stock. The
market price of the Common Stock could be subject to significant fluctuations in
response to the Company's operating results and other factors, some of which may
be beyond the Company's control. There can be no assurance that the market price
of the Common Stock will not decline below the price at which the shares of the
Common Stock are sold in this Offering.

                                  THE COMPANY
 
    The Company was formed to acquire R.J. Tower Corporation (the
"Predecessor"), the acquisition of which was completed in April 1993 (the "R.J.
Tower Acquisition") for an aggregate cost of approximately $26 million. Since
the R.J. Tower Acquisition, the Company has successfully completed and fully
integrated four strategic acquisitions:
 
    EDGEWOOD.  In May 1994, the Company acquired Edgewood Tool and Manufacturing
Company and its affiliate, Ann Arbor Assembly Corporation (collectively,
"Edgewood") for approximately $30 million in aggregate consideration. Edgewood
is a leading supplier of hood and deck lid hinges as well as structural
stampings and assemblies. The acquisition of Edgewood: (i) added engineered
mechanical stampings, primarily hood and deck lid hinges, and additional
structural components to the Company's product offerings; (ii) increased model
penetration with the Company's existing customers; and (iii) provided the
Company with a significant new customer, Mazda.
 
    KALAMAZOO.  In June 1994, the Company acquired Kalamazoo Stamping and Die
Company ("Kalamazoo"), a supplier of structural stampings and assemblies, for
approximately $12 million in cash. The acquisition of Kalamazoo added additional
structural components to the Company's product offerings and increased model
penetration with Ford.
 
    TRYLON.  In January 1996, the Company acquired Trylon from MascoTech for
approximately $25 million in cash, including transaction costs. The Trylon
Acquisition: (i) broadened the Company's product offerings to include small,
precision metal stampings and assemblies, which were previously outsourced to
third parties; (ii) established a relationship between the Company and General
Motors; and (iii) increased content on Ford models, primarily the Villager.
Trylon generated $47.9 million in revenues in 1995.
 
    MSTI.  In May 1996, the Company acquired MSTI from MascoTech for
approximately $79 million (including the payment of related fees and expenses),
plus additional earn-out payments if certain operating targets are achieved by
the MSTI facilities in the first three years following the acquisition. The MSTI
Acquisition: (i) expanded the Company's product capabilities into chassis and
suspension components; (ii) provided chassis and suspension technology as well
as value-added processing technologies including assembling, painting and
welding; and (iii) increased the Company's content per vehicle on key light
truck and sport utility vehicles such as the Ford F-Series, Explorer and
Windstar and the Chrysler Ram and Dakota as well as on high volume passenger
cars such as the Ford Taurus/Sable. MSTI had revenues of $152.9 million in 1995.
 
    The Company completed an initial public offering (the "IPO") of its Common
Stock in August 1994 and the sale of an additional 2,232,900 shares in June
1996. The Company's principal executive offices are located at 4508 IDS Center,
Minneapolis, Minnesota 55402, and its telephone number is (612) 342-2310.
 
                           APC ACQUISITION FINANCING
 
   
    The Company expects to complete the APC Acquisition by the end of April
1997. The aggregate purchase price of APC is approximately $625 million, plus an
additional $25 million for related fees and expenses and management's estimate
of certain post-closing adjustments. The Company has executed a commitment
letter with its principal bank lender pursuant to which such lender has agreed,
subject to the satisfaction of certain conditions, to enter into the New Credit
Agreement. The Company anticipates that the New Credit Agreement will provide
for a six year revolving credit facility of up to $750 million (the "Revolving
Credit Facility.") The Company intends to finance the APC Acquisition by using
the proceeds from this Offering and a portion of its available borrowings under
the New Credit Agreement. In the event that the Offering has not been completed
at the time of the consummation of the APC Acquisition, an additional loan of up
to $200 million will be made available to the Company under the New Credit
Agreement in the form of a term loan. This loan would have a term of 18 months
and would be fully repaid from the proceeds of the Offering. See "Description of
New Credit Agreement."

(2) Includes the redemption of the Senior Notes in aggregate principal amount of
    $65.0 million and a prepayment penalty of approximately $3.9 million. The
    Senior Notes were issued by the Company in May 1996 to finance the cash
    portion of the purchase price of MSTI.
 
                                USE OF PROCEEDS
 
   
    The net proceeds to be received by the Company from the sale of the
8,500,000 shares of Common Stock offered by the Company hereby (at an assumed
public offering price of $39.63 per share and after deducting the underwriting
discounts and commissions and estimated offering expenses payable by the
Company) are estimated to be $322.0 million ($379.6 million if the Underwriters'
over-allotment option is exercised in full). The Company expects to use the net
proceeds to pay a portion of the cash purchase price of the APC Acquisition. The
Company expects to use borrowings under the New Credit Agreement of $357.3
million, together with cash on hand of $39.6 million, to pay the remaining
portion of the purchase price of the APC Acquisition.
    
 
   
    In the event that the APC Acquisition is not consummated, the Company
reserves the right to use the net proceeds of the Offering for general corporate
purposes, which may include repayment of existing indebtedness, acquisitions or
capital expenditures. Pending such uses, the Company expects that such proceeds
will be invested in short-term, interest bearing, investment grade securities.
See "Risk Factors-- Risks Associated with the Failure to Complete the APC
Acquisition."
    
 
   
    The Company is continually evaluating possible acquisitions and engages in
discussions with acquisition candidates from time to time. The Company does not
currently have any pending acquisitions that are probable other than as
described herein.
    
 
    The Company will not receive any of the proceeds from the sale of Common
Stock by the Selling Stockholders. See "Selling Stockholders."

    The reported last sale price of the Common Stock on the NYSE as of a recent
date is set forth on the cover page of this Prospectus.
    
 
    As of December 31, 1996, there were approximately 125 holders of record of
the outstanding Common Stock. The Company believes it has a significantly larger
number of beneficial holders of its Common Stock.
 
                                DIVIDEND POLICY
 
    The Company has not declared or paid any cash dividends on its Common Stock
in the past, currently intends to retain its earnings to support its growth
strategy and does not anticipate paying dividends in the foreseeable future. Any
future payment of dividends is within the discretion of the Company's Board of
Directors and will depend upon, among other factors, the capital requirements,
operating results and financial condition of the Company from time to time. In
addition, the Company's ability to pay cash dividends is expected to be limited
by the terms of the New Credit Agreement. As of December 31, 1996, under the
most restrictive terms of the New Credit Agreement as currently proposed, the
Company would not have been permitted to pay any dividends. See "Management's
Discussion and Analysis of Results of Operations and Financial

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS
 
   
    The following Unaudited Pro Forma Statement of Operations for the year ended
December 31, 1996 gives effect to: (i) the MSTI Acquisition (including related
financing transactions); (ii) the 1996 Offering and the application of the net
proceeds therefrom; (iii) the APC Acquisition; (iv) the refinancing of the
Existing Credit Agreement and redemption of the Senior Notes; and (v) the
Offering and the application of the net proceeds therefrom to the Company as
described in "Use of Proceeds," as if such transactions had occurred on January
1, 1996. The Company acquired Trylon on January 16, 1996. Results of operations
of Trylon for the period from January 1, 1996 through the acquisition date are
not material and therefore have not been included in the Company's results of
operations for the year ended December 31, 1996 on a pro forma basis. See "The
Company" and "Use of Proceeds" on pages 13 and 14, respectively, for a more
detailed description of the transactions included in the Unaudited Pro Forma
Financial Statements.
    
 
    The information set forth under the heading Pro Forma As Adjusted included
in the Unaudited Pro Forma Balance Sheet as of December 31, 1996 reflects: (i)
the APC Acquisition; (ii) the refinancing of the Existing Credit Agreement and
redemption of the Senior Notes; and (iii) the Offering and the application of
the net proceeds therefrom to the Company as described under "Use of Proceeds,"
as if such transactions had occurred on such date. The historical balance sheet
of the Company as of December 31, 1996 already reflects the Trylon Acquisition,
the MSTI Acquisition and the 1996 Offering.
 
    The Company expects to achieve cost savings through the integration of the
operations of APC with those of the Company. See "Business--APC Acquisition."
The Unaudited Pro Forma Financial Statements set forth herein do not reflect any
of these anticipated cost savings.
 
   
    The Company expects to complete the APC Acquisition by the end of April
1997. Pursuant to the terms of the purchase agreement, the Company may elect not
to complete the APC Acquisition if there is a material adverse change in the
operating results or financial condition of APC prior to the closing date.
Currently, the Company believes that such a change has not occurred and that it
is unlikely that such a change will occur prior to the closing date. If the APC
Acquisition is not consummated, the size of the Company will not increase, but
the number of outstanding shares will have, and thus the value of each share of
Common Stock would be significantly diluted. The Company's EPS for 1996 on a pro
forma as adjusted basis would have been $2.25 per share. If the APC Acquisition
is not completed, the Company's EPS for 1996 on a pro forma as adjusted basis
would have been $1.17 per share. See "Risk Factors--Risks Associated with the
Failure to Complete the APC Acquisition." The Company is required to pay A.O.
Smith a fee of $15.0 million in the event that the APC Acquisition is not
completed. The Company currently believes that the APC Acquisition will be
completed. As a result, the Company has not reflected this payment in the
accompanying Unaudited Pro Forma Financial Statements.
    
 
    The unaudited pro forma financial data presented herein are based on the
assumptions and adjustments described in the accompanying notes. The Unaudited
Pro Forma Statement of Operations does not purport to represent what the
Company's results of operations actually would have been if the events described
above had occurred as of the dates indicated or what such results will be for
any future periods. The Unaudited Pro Forma Financial Statements are based upon
assumptions and adjustments that the Company believes are reasonable. The
Unaudited Pro Forma Financial Statements and the accompanying notes should be
read in conjunction with the historical financial statements of the Company and
of APC, including the notes thereto, included elsewhere in this Prospectus.
 
   
    Each of the acquisitions referred to in these Unaudited Pro Forma Financial
Statements have been or will be accounted for using the purchase method of
accounting and, accordingly, the assets acquired and liabilities assumed have
been or will be recorded at their fair values as of the dates of their
respective acquisitions. These amounts have been recorded based upon preliminary
estimates as of the dates of the acquisitions. The Company does not believe that
any changes to these estimates that may occur will have a material impact on the
pro forma financial information included herein.

              NOTES TO UNAUDITED PRO FORMA STATEMENT OF OPERATIONS
                             (DOLLARS IN THOUSANDS)
 
 (1) Represents the results of operations of the Company for the year ended
    December 31, 1996 and the results of operations of Trylon and MSTI from the
    dates of their respective acquisitions.
 
 (2) Represents the results of operations for MSTI from January 1, 1996 through
    the date of acquisition, May 31, 1996.
 
 (3) Represents the results of operations for APC for the year ended December
    31, 1996.
 
 (4) To eliminate sales of stampings from the Company to APC during 1996.
 
 (5) To eliminate purchases made by APC from the Company during 1996 of $13,600
    (See Note 4) and to reflect the change in depreciation expense resulting
    from adjustments to the depreciable lives of property, plant and equipment
    of MSTI and APC to their estimated useful lives at the time of their
    acquisition and from adjustments to value such property, plant and equipment
    at fair value as of the dates of acquisition ($17,862).
 
 (6) Represents the amortization of goodwill arising from the acquisition of
    MSTI ($415) and APC ($4,633), net of amortization of goodwill previously
    recorded by MSTI ($683) which has been eliminated. Goodwill will be
    amortized on a straight-line basis over a forty-year period.
 
   
 (7) Represents incremental interest expense arising from indebtedness incurred
    in connection with the acquisitions of MSTI ($2,314) and APC ($40,069), net
    of the reduction in interest expense which results from the application of
    the proceeds from the 1996 Offering ($993) and the Offering ($26,750).
    Adjustments to interest expense have been calculated based on an assumed
    weighted average borrowing rate of 6.75% during the pro forma period. If the
    assumed interest rate were to change by 1/8 of 1%, interest expense would
    change by approximately $440 and net income would change by approximately
    $265.
    
 
 (8) To adjust the provision for income taxes on a pro forma basis to reflect
    the Company's incremental tax rate of 40%.
 
 (9) Represents the payment of a prepayment penalty of $3,900 on the redemption
    of the Senior Notes and the write-off of $1,100 of related deferred
    financing costs, net of the related income tax effect of $2,000.
 
(10) Represents the pro forma effect from the shares issued to MascoTech in
    connection with the MSTI Acquisition, the 2,232,900 shares issued in the
    1996 Offering, including shares issued upon the exercise of the
    underwriters' over-allotment option, and the issuance of 8,500,000 shares of
    the Common Stock in the Offering.

(2) To record inventories at estimated fair value, including the elimination of
    APC's historical LIFO reserve.
    
 
   
(3) To write off APC's historical deferred tax benefit.
    
 
   
(4) To state property, plant and equipment acquired in the APC Acquisition at
    estimated fair value and eliminate historical accumulated depreciation.
    
 
   
(5) To adjust goodwill to the amount recognized in connection with the APC
    Acquisition. The goodwill will be amortized on a straight-line basis over a
    forty-year period.
    
 
   
(6) To reflect the financing transactions related to the APC Acquisition and the
    application of the net proceeds to the Company of the Offering. Upon the
    consummation of the APC Acquisition, the Company intends to refinance the
    Existing Credit Agreement and retire certain other indebtedness with
    borrowings under the New Credit Agreement. See "Description of New Credit
    Agreement" for a detailed description of the terms of the New Credit
    Agreement. In connection with the retirement of certain indebtedness, the
    Company will write-off $1,100 of previously capitalized deferred financing
    costs and expects to pay a prepayment penalty of $3,900 on the redemption of
    the Senior Notes. This will result in a reduction in current income taxes
    payable of $2,000 and an extraordinary loss, net of income taxes, of $3,000.
    
 
    The following table sets forth the sources and uses of funds in the APC
    Acquisition:

(7) To write off historical deferred taxes of $35,700 and to record management's
    preliminary estimate of reserves to be established in connection with the
    APC Acquisition, including $15,500 of losses to be incurred on the sale of
    products which have costs in excess of selling prices and $4,500 of costs to
    be incurred to rationalize certain facilities of APC. These reserves have
    been established based on preliminary estimates.

(1) On April 15, 1993, the Company acquired the Predecessor. Accordingly,
    certain information provided for the year ended December 31, 1992, and the
    three and one-half month period ended April 14, 1993, is not comparable to
    the Statement of Operations Data of the Company due to the effects of
    certain purchase accounting adjustments and the financing of the R.J. Tower
    Acquisition. See "Management's Discussion and Analysis of Results of
    Operations and Financial Condition."
 
(2) Operating data for the Predecessor for the period January 1, 1993 to April
    14, 1993 have been combined for presentation purposes with the operating
    data of the Company for the eight and one-half month period ended December
    31, 1993, without giving effect to purchase accounting or the impact of the
    financing of the R.J. Tower Acquisition.
 
(3) Includes the results of operations of MSTI from the date of acquisition, May
    31, 1996.
 
   
(4) The Company has not declared or paid any cash dividends on its Common Stock
    in the past, currently intends to retain its earnings to support its growth
    strategy and does not anticipate paying dividends in the foreseeable future.
    See "Dividend Policy."
    
 
   
(5) "EBITDA" is operating income plus amortization and depreciation. EBITDA does
    not represent and should not be considered an alternative to net income or
    cash flow from operations as determined by GAAP and the Company's
    calculation thereof may not be comparable to that reported by other
    companies. The Company believes that it is widely accepted that EBITDA
    provides useful information regarding a company's ability to service and/or
    incur indebtedness. This belief is based on the Company's negotiations with
    its lenders who have indicated that the amount of indebtedness the Company
    will be permitted to incur will be based, in part, on the Company's EBITDA.
    EBITDA does not take into account the Company's working capital
    requirements, debt service requirements and other commitments and,
    accordingly, is not necessarily indicative of amounts that may be available
    for discretionary uses. Set forth below is a reconciliation of the Company's
    operating income, as reported, to EBITDA for the periods indicated:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION
 
GENERAL
 
   
    The Company was organized to effect the R.J. Tower Acquisition, which was
financed with a combination of common equity and secured indebtedness. Since the
R.J. Tower Acquisition, the Company has successfully completed and fully
integrated four strategic acquisitions. See "The Company." The Company expects
to complete the APC Acquisition by the end of April 1997. No assurance can be
given, however, that the APC Acquisition will be completed. See "Risk
Factors--Risks Associated with the Failure to Complete the APC Acquisition."
    
 
    The Company's four previous acquisitions have affected, and the APC
Acquisition will prospectively affect, the Company's results of operations in
certain significant respects. As a result of the APC Acquisition, the Company
will increase the historical book value of APC's assets, including intangible
assets such as goodwill, which will significantly increase the amount of
amortization expense reported in the Company's ongoing operations. In addition,
the Company's interest expense will increase significantly due to increased
borrowings to finance the APC Acquisition. The Company expects to achieve cost
savings through the integration of the operations of APC with those of the
Company.
 
    The Company believes that its overall gross margin has been slightly higher
than that of APC, primarily because the Company has historically sold a greater
percentage of complex, high value-added products than APC. In addition, APC's
overall gross margin has been negatively impacted in recent years as a result of
APC's beginning production of certain products that require a greater proportion
of components purchased from outside suppliers and higher launch costs and
depreciation expense related to the new production. The Company expects that, as
a result of the APC Acquisition, its overall gross margin will be lower in
future periods.

COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995
 
    REVENUES.  Revenues for the year ended December 31, 1996 increased by $177.1
million, or 79.5%, to $399.9 million compared to $222.8 million for the year
ended December 31, 1995. Approximately $134.3 million of the increase in
revenues over 1995 is attributable to the acquisitions of MSTI in May 1996 and
Trylon in January 1996. The remaining increase is due to new business awarded to
the Company, including
 
                                       25
<PAGE>
business relating to the Ford Escort, Econoline and Expedition, Dodge Ram Club
Cab pick-up and Toyota Camry. These increases were partially offset by
production decreases in the first half of the year on key models served by the
Company, including the Ford Aerostar, Villager, Econoline and Chrysler Intrepid/
Concorde/Vision.
 
    COST OF SALES.  Cost of sales as a percentage of revenues for the year ended
December 31, 1996 was 84.6% compared to 83.2% for the year ended December 31,
1995. The decrease in gross margin was due to a higher proportion of components
purchased from outside suppliers as a result of the Trylon and MSTI Acquisitions
and launch costs associated with new business. These decreases were partially
offset by operating efficiencies and enhanced productivity.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased to $20.0 million, or 5.0% of revenues, for the
year ended December 31, 1996 compared to $14.3 million, or 6.4% of revenues, for
the year ended December 31, 1995. The percentage decrease related to revenues
reflects the economies of scale of higher gross sales. The increased expense was
due primarily to incremental costs associated with the Company's acquisitions of
MSTI and Trylon in 1996.
 
    AMORTIZATION EXPENSE.  Amortization expense for the year ended December 31,
1996 was $2.2 million compared to $1.2 million for the year ended December 31,
1995. The increase was due to incremental goodwill amortization related to the
acquisitions of MSTI and Trylon.
 
    INTEREST EXPENSE.  Interest expense for the year ended December 31, 1996 was
$5.1 million compared to $1.8 million for the year ended December 31, 1995. The
increase was due principally to increased borrowings incurred to fund the
acquisitions of MSTI and Trylon, partially offset by the application of the
proceeds from the 1996 Offering, and the absence of capitalization of interest
costs for the new Bardstown, Kentucky plant which was under construction during
1995.
 
    INCOME TAXES.  The effective income tax rate was 39.9% for the year ended
December 31, 1996 and 40.0% for the year ended December 31, 1995. The effective
rates differed from the statutory rates primarily as a result of state taxes and
nondeductible goodwill amortization.
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994
 
   
    REVENUES.  Revenues for the year ended December 31, 1995 increased $57.3
million, or 34.6%, to $222.8 million compared to $165.5 million for the year
ended December 31, 1994. Revenues increased despite significant production
decreases on key vehicles served by the Company including the Ford Escort,
Taurus/Sable, and Econoline and Chrysler Intrepid/Concorde/Vision. These
decreases were offset by new business that began production during the year and
the full year effects of the Company's acquisitions of Edgewood in May 1994 and
Kalamazoo in June 1994.
    
 
    COST OF SALES.  Cost of sales, as a percentage of revenues, decreased to
83.2% for the year ended December 31, 1995 compared to 86.4% for the year ended
December 31, 1994. The improvement in gross margin was a result of the
productivity improvement initiatives in place and synergies realized from the
acquisitions of Edgewood and Kalamazoo. These were partially offset by higher
raw material costs.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased to $14.3 million, or 6.4% of revenues, for the
year ended December 31, 1995 compared to $7.4 million, or 4.5% of revenues, for
the year ended December 31, 1994. The increased expense was due in part to the
full year effect of the acquisitions of Edgewood and Kalamazoo combined with the
incremental engineering, technical and development costs associated with future
programs.
 
    OTHER.  Amortization expense increased to $1.2 million for the year ended
December 31, 1995 from $0.8 million for the year ended December 31, 1994 due to
incremental goodwill amortization related to the Company's 1994 acquisitions.
Interest expense decreased to $1.8 million in 1995 from $1.9 million in 1994.
 
                                       26
<PAGE>
   
The decrease is due to the effect of the application of the proceeds from the
Company's IPO to reduce indebtedness. The provision for income taxes was at an
effective rate of 40.0% for the year ended December 31, 1995 and 40.7% for the
year ended December 31, 1994. The effective rates were higher than federal
statutory rates as a result of nondeductible goodwill amortization and state
income taxes.

</TABLE>
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995
 
    REVENUES.  Revenues for the year ended December 31, 1996 increased $17.7
million, or 2.1%, to $863.0 million compared to $845.3 million for the year
ended December 31, 1995. This increase in revenue is attributable to new
business associated with the redesigned Nissan pick-up and the effects of the
full year's production of the Dodge Ram Club Cab pick-up, as well as overall
production increases on key vehicles served by APC, including the Ford
Taurus/Sable and the General Motors Yukon/Chevrolet Tahoe. These increases were
partially offset by lower production of the Dodge Dakota pick-up as a result of
the launch of a redesigned version of this vehicle during 1996.
 
    COST OF SALES.  Cost of sales, as a percentage of revenues, was 89.2% for
the year ended December 31, 1996, compared to 88.7% for the year ended December
31, 1995. APC's gross margin was negatively impacted by higher incremental costs
associated with the launch of new products during 1996, along with relative
increases in depreciation expense associated with capital equipment placed in
service during 1995 and 1996 related to this new business. These increases were
partially offset by improved labor efficiencies and productivity.
 
   
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses were $37.2 million, or 4.3% of revenues, for the year
ended December 31, 1996 compared to $37.4 million for the prior year, a decrease
of approximately 0.5%. These costs include incremental design and engineering
expenditures associated with new business to be introduced in future periods,
including the Ford Ranger, which was launched late in 1996, the Dodge Durango,
Chrysler's entry into the sport utility market, and the front and rear
suspension modules for the Chrysler Intrepid/Concorde/Vision. These incremental
costs were offset by lower overall general and administrative costs.
    
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994
 
    REVENUES.  Revenues for the year ended December 31, 1995 increased $122.6
million, or 17.0%, to $845.3 million compared to $722.7 million for the year
ended December 31, 1994. This increase was attributable to new business
associated with the launches of the redesigned Ford Explorer and General Motors
Yukon/Chevrolet Tahoe, as well as the effect of the full year's production of
the Ford Contour/ Mercury Mystique, which was launched during 1994.
 
                                       27
<PAGE>
    COST OF SALES.  Cost of sales, as a percentage of revenues, was 88.7% for
the year ended December 31, 1995, compared to 86.4% for the year ended December
31, 1994. Higher costs associated with the launch of new products during 1995
contributed to the overall increase in these costs. In addition, APC also
experienced higher relative labor costs as a result of the increase in overall
product demand during 1995. Higher depreciation expense associated with capital
equipment used in the production of new products launched during 1994 and 1995
also contributed to these higher costs. Gross margin was also negatively
impacted as a result of APC's beginning production of certain products that
require a greater proportion of components purchased from outside suppliers.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses were $37.4 million, or 4.5% of revenues, for the year
ended December 31, 1995 compared to $34.0 million, or 4.7% of revenues, for the
prior year, an increase of approximately 10.0%. Higher design and engineering
costs associated with products to be launched in future periods, including the
redesigned Ford Ranger and Dodge Dakota pick-ups, contributed to this increase.
In addition, selling and general administrative costs increased to support the
overall higher revenues in 1995 compared to 1994.
 
SEASONALITY
 
    The Company's performance is dependent on automotive vehicle production,
which is seasonal in nature. The third calendar quarter is historically the
weakest, due to the impact of OEM plant shutdowns in July for vacation and model
changeovers. Additionally, general industry levels are only a partial
explanation of volume changes throughout the year. Individual vehicle platforms
are also a cause of variations in revenues depending upon market response and
acceptance of the specific platform models.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At December 31, 1996, the Company had no indebtedness outstanding under the
revolving credit facility portion of its Existing Credit Agreement. The Existing
Credit Agreement consists of a revolving credit facility with a committed amount
of $75.0 million (subject to eligible accounts receivable and inventory, as
defined in the Existing Credit Agreement, which exceeded $75.0 million at
December 31, 1996). The Existing Credit Agreement matures in January 2001 and
bears interest at variable rates equal to, at the Company's option, either a
prime-based rate or LIBOR plus a variable margin. The Existing Credit Agreement
provides for the issuance of up to $50 million in letters of credit to
collateralize the outstanding IRBs described below.
 
    At December 31, 1996, the Company also had $43.8 million of indebtedness
outstanding pursuant to IRBs issued with the City of Bardstown, Kentucky.
Proceeds from these IRBs were used to finance construction of a 240,000 square
foot manufacturing facility and the related purchase of equipment. The Bardstown
IRBs, which mature on June 1, 2024 and March 1, 2025, are collateralized by a
letter of credit. As of December 31, 1996, $34.2 million of the proceeds had
been expended or committed for the first phase of the facility and related
equipment. The unexpended proceeds from the Bardstown IRBs of $10.8 million at
December 31, 1996, are invested in treasury securities and will be used to
finance the second phase of the facility. These IRBs bear interest at a floating
rate which is adjusted weekly as determined by the bond remarketing agent (5.8%
at December 31, 1996). The second phase of the facility, which includes the
purchase and installation of additional processing equipment, is anticipated to
be completed by the end of 1998.
 
    At December 31, 1996, the Company had $2.9 million in outstanding
indebtedness relating to IRBs issued in connection with the construction of its
Auburn, Indiana plant. The Auburn IRBs are collateralized by a letter of credit,
certain equipment and a mortgage on the Company's Auburn, Indiana plant. The
Auburn IRBs are payable in annual installments of $720,000 through September
2000 and bear interest at a floating rate which is adjusted weekly as determined
by the bond remarketing agent (4.4% at December 31, 1996).
 
                                       28
<PAGE>
    On January 16, 1996, the Company acquired all of the outstanding common
stock of Trylon for total cash consideration of approximately $25 million, which
included transaction costs. To finance the acquisition, the Company incurred a
$25.0 million term loan, which was repaid in May 1996 using a portion of the
proceeds from the sale of the Senior Notes and borrowings under the Existing
Credit Agreement.
 
   
    On May 31, 1996, the Company purchased all of the outstanding common stock
of MSTI from MascoTech for an aggregate purchase price of approximately $79
million, including payment of related fees and expenses. Pursuant to the terms
of the acquisition, the Company is required to make additional earn-out payments
to MascoTech if certain operating targets are achieved by the MSTI facilities in
the first three years following the acquisition. If all such operating targets
are met, the total payments will not exceed $30.0 million.
    
 
    The Company financed the cash portion of the purchase price of MSTI through
the issuance in two series of Senior Notes having an aggregate principal amount
of $65.0 million. The $40.0 million of Series A Senior Notes have a final
maturity on June 1, 2006 and require annual principal payments commencing on
June 1, 2000 and continuing every year thereafter until their final maturity.
The $25.0 million of Series B Senior Notes have a final maturity on June 1, 2008
and require annual principal payments commencing on June 1, 2004 and continuing
every year thereafter until their final maturity. The Senior Notes require the
Company to make semi-annual interest payments commencing December 1, 1996. Net
proceeds from the sale of the Senior Notes in excess of the amounts used to
finance the cash portion of the MSTI Acquisition were used, together with
borrowings under the revolving credit facility, to repay in full the remaining
balance outstanding on the $25.0 million term loan incurred by the Company in
connection with the Trylon Acquisition.
 
    In June 1996, the Company completed an offering of 2,232,900 shares of
Common Stock at an offering price of $24.50 per share. Approximately $32 million
of the net proceeds from the 1996 Offering were used by the Company to retire
borrowings under its Existing Credit Agreement. The remaining proceeds are
included in cash and cash equivalents in the December 31, 1996 consolidated
balance sheet and will be used for other general corporate purposes, which may
include prepayment of other indebtedness, acquisitions or capital expenditures.
 
    During the year ended December 31, 1996, the Company generated $30.0 million
of cash from operations, which was partially used to fund capital expenditures.
 
    The Company has made substantial investments in manufacturing technology and
product design capability to support its products. The Company made capital
expenditures of approximately $16.3 million for the year ended December 31,
1996, primarily for equipment and dedicated tooling purchases related to new or
replacement programs.
 
LIQUIDITY AND CAPITAL RESOURCES FOLLOWING THE APC ACQUISITION
 
    The aggregate purchase price of the APC Acquisition is approximately $625
million, plus an additional $25 million for related fees and expenses and
management's estimates of certain post-closing adjustments. The Company expects
to complete the APC Acquisition by the end of April 1997. This acquisition will
be accounted for as a purchase and, accordingly, APC's assets and liabilities
will be recorded at fair value as of the acquisition date, with any excess
purchase price recorded as goodwill.
 
   
    In connection with the APC Acquisition, the Company expects to enter into
the New Credit Agreement. The New Credit Agreement will provide for borrowings
under the Revolving Credit Facility of up to $750 million over six years. In
addition, a term loan facility with up to $200 million in borrowings, payable
within 18 months, will be made available in the event the APC Acquisition is
completed prior to the completion of the Offering. Interest will be payable on
borrowings under the New Credit Agreement at the bank's Base Rate or the reserve
adjusted LIBOR Rate plus a margin ranging from 17 to 50 basis points, depending
upon the ratio of the consolidated indebtedness of the Company to stockholders'
    
 
                                       29
<PAGE>
   
investment. The New Credit Agreement will also include certain restrictive
covenants, which the Company expects will be similar in nature to those in the
Existing Credit Agreement. The New Credit Agreement will become effective
contemporaneously with the completion of the APC Acquisition.
    
 
    Proceeds from borrowings under the New Credit Agreement will be used to: (i)
finance the APC Acquisition; (ii) refinance existing indebtedness of the
Company, including the redemption of the Senior Notes; and (iii) pay transaction
fees and expenses associated with the APC Acquisition. In connection with the
redemption of the Senior Notes, the Company will record an extraordinary loss of
approximately $3.0 million, net of income taxes, related to prepayment penalties
and the write-off of previously capitalized deferred financing costs.
 
    Proceeds from this Offering will be used to fund a portion of the purchase
price related to the APC Acquisition or to repay indebtedness incurred under the
New Credit Agreement in the event that the APC Acquisition is consummated prior
to the completion of the Offering.
 
    APC's capital expenditures for the year ended December 31, 1996 were
approximately $152 million, of which approximately $63 million was used to
finance the construction and to purchase equipment for its new Plymouth,
Michigan and Roanoke, Virginia manufacturing facilities. APC's remaining capital
expenditures were used primarily to purchase equipment and dedicated tooling
related to new or replacement programs. The Company's capital expenditures for
the year ended December 31, 1996 on a pro forma basis were approximately $168
million. After completing the APC Acquisition, the Company expects its budget
for capital expenditures during the remainder of 1997 to be approximately $75
million. Capital expenditures in 1997 are expected to be financed either with
cash generated from operations or borrowings under the New Credit Agreement.
 
    The Company believes the borrowing availability under the New Credit
Agreement, together with funds generated by operations, should provide the
Company with the liquidity and capital resources to pursue its business strategy
through 1997, with respect to working capital, capital expenditures and other
operating needs. Under present conditions, management does not believe access to
funds will restrict its ability to pursue its acquisition strategy.
 
EFFECTS OF INFLATION
 
    Inflation generally affects the Company by increasing the interest expense
of floating rate indebtedness and by increasing the cost of labor, equipment and
raw materials. Management believes that inflation has not significantly impacted
the Company's business over the past 12 months. However, because selling prices
generally cannot be increased until a model changeover, the effects of inflation
must be offset by productivity improvements and volume from new business awards.

GENERAL
 
   
    The Company is a leading designer and producer of high-quality body
structure components and assemblies used by the major North American automotive
OEMs, Ford, Chrysler and General Motors, and certain Transplants, including
Honda, Toyota, Nissan and Mazda. The Company's current products range from large
structural stampings and assemblies, such as body pillars, chassis, suspension
and floor pan components and major housing assemblies, to engineered assemblies,
such as hood and deck lid hinges and brake components. On January 27, 1997, the
Company agreed to acquire A.O. Smith's APC division, a leading manufacturer of
light truck frames, automotive engine cradles and other structural and
suspension components, assemblies and modules used by major North American OEMs
and Transplants. Following the APC Acquisition, the Company believes it will be
one of the largest independent suppliers of structural components and assemblies
to the North American automotive market (based on net sales).
    
 
   
    Since its inception in April 1993, the Company's revenues have grown rapidly
through a focused strategy of internal growth and a highly disciplined
acquisition program. During the last three years, the Company has successfully
completed and fully integrated four acquisitions. As a result of such
acquisitions and internal growth, the Company's revenues have increased from $86
million in 1993 to approximately $474 million in 1996 (pro forma only for the
MSTI Acquisition), representing a compound annual growth rate of approximately
76%. The Company's North American content per vehicle has increased from $6.23
in 1993 to $26.74 in 1996 on an actual basis. The APC Acquisition will be the
Company's largest acquisition to date and will increase the Company's pro forma
revenues to approximately $1.3 billion and its pro forma North American content
per vehicle to $77.49 for 1996.
    
 
INDUSTRY TRENDS
 
    The Company's performance and growth is directly related to certain trends
within the automotive market, including the consolidation of the component
supply industry, the increase in global sourcing and the growth of
system/modular sourcing.
 
    SUPPLIER CONSOLIDATION.  The automotive supply industry has recently begun
to undergo significant consolidation. To lower costs and improve quality, OEMs
are reducing their supplier base by awarding sole-source contracts to
full-service suppliers who are able to supply larger segments of a vehicle.
OEMs' criteria for supplier selection include not only cost, quality and
responsiveness, but also full-service design, engineering and program management
capabilities. For full-service suppliers such as the Company, the new
environment provides an opportunity to grow by obtaining business previously
provided by other non-full service suppliers and by acquiring suppliers that
further enhance product, manufacturing and service capabilities. OEMs rigorously
evaluate suppliers on the basis of product quality, cost control, reliability of
delivery, product design capability, financial strength, new technology
implementation, quality and condition of facilities and overall management.
Suppliers that obtain superior ratings are considered for sourcing new business.
Although these new supplier policies have already resulted in significant
consolidation of component suppliers in certain segments, the Company believes
that consolidation within the
 
                                       31
<PAGE>
structural and suspension component segments of the automotive industry will
continue to provide attractive opportunities to acquire high-quality companies
that complement its existing business.
 
    GLOBAL SOURCING.  Regions such as Asia, Latin America, Mexico and Eastern
Europe are expected to experience significant growth in vehicle demand over the
next ten years. OEMs are positioning themselves to reach these emerging markets
in a cost-effective manner by seeking to design and produce "world cars" which
can be designed in one vehicle center to a single global standard but produced
and sold in different geographic markets, thereby allowing OEMs to reduce design
costs, take advantage of low-cost manufacturing locations and improve product
quality and consistency. OEMs increasingly are requiring their suppliers to have
the capability to design and manufacture their products in multiple geographic
markets.
 
    SYSTEM/MODULAR SOURCING.  OEMs are increasingly seeking suppliers capable of
providing complete systems or modules rather than suppliers who only provide
separate component parts. A system is a group of component parts which operate
together to provide a specific engineering driven functionality whereas a module
is a group of systems and/or component parts which are assembled and shipped to
the OEM for installation in a vehicle as a unit. By outsourcing complete systems
or modules, OEMs are able to reduce their costs associated with the design and
integration of different components and improve quality by enabling their
suppliers to assemble and test major portions of the vehicle prior to beginning
production. As a result of the APC Acquisition, the Company will be in an
improved position to capitalize on this trend by designing its products to
function together and by providing designs that are integrated into the design
of the entire vehicle.
 
STRATEGY
 
   
    The Company's business objective is to capitalize upon the consolidation,
globalization and system/ modular sourcing trends in the automotive supply
industry in order to be the leading provider of structural and suspension
components to OEMs on a worldwide basis. Key elements of the Company's operating
and growth strategies are outlined below:
    
 
OPERATING STRATEGY
 
    FULL-SERVICE TECHNICAL DESIGN, ENGINEERING AND PROGRAM MANAGEMENT
CAPABILITIES.  The Company strives to maintain a competitive advantage through
investment in research and product development, advanced engineering and program
management. The Company works with OEMs throughout the product development
process from concept vehicle and prototype development through the design and
implementation of manufacturing processes to provide full-service capabilities
to its customers. In some cases, the Company places design engineers at customer
facilities to coordinate its product design efforts with those of its OEM
customers.
 
    EFFICIENT MANUFACTURING/CONTINUOUS IMPROVEMENT PROGRAMS.  In response to
OEMs' increasingly stringent demands, the Company has implemented manufacturing
practices designed to maximize product quality and timeliness of delivery and
eliminate waste and inefficiency. The Company has continued to upgrade its
manufacturing equipment and processes through substantial investment in new
equipment, maintenance of existing equipment and utilization of manufacturing
engineering personnel.
 
    GLOBAL PRESENCE.  The Company strives to offer manufacturing and support
services to its customers on a global basis through a combination of
international wholly owned facilities and by entering into joint ventures and
partnerships with foreign suppliers. Since 1993, in furtherance of its global
expansion strategy, the Company has opened a European sales and engineering
office to service U.K. and German OEM customers and has established an
industrial partnership with The Kirchhoff Group ("Kirchhoff") in Germany. With
the APC Acquisition, the Company will further expand its ability to service OEMs
on a global basis. The Company also has relocated certain technical personnel
resources to locations where OEMs are developing "world cars."

    DECENTRALIZED, PARTICIPATIVE CULTURE.  The Company's decentralized approach
to managing its manufacturing facilities encourages decision making and employee
participation in areas such as manufacturing processes and customer service. The
Company's management team meets frequently at various Company locations in order
to maintain a unified Company culture. To increase employee productivity, the
Company utilizes incentive programs for all salaried and hourly employees and
provides incentives for employees who take advantage of its continuous
improvement programs and who provide cost savings ideas.
 
GROWTH STRATEGY
 
    STRATEGIC ACQUISITIONS.  The Company continues to believe that consolidation
in the automotive supply industry will provide further attractive opportunities
to acquire high-quality companies that complement its existing business. The
Company seeks to make acquisitions that (i) provide additional product,
manufacturing and technical capabilities; (ii) broaden the Company's geographic
coverage domestically and strengthen its ability to supply products on a global
basis; (iii) increase the number of models for which the Company supplies
products and the content supplied for existing models; and (iv) add new
customers. With the consummation of the APC Acquisition, the Company will have
acquired five businesses since 1993. The Company intends to seek future
acquisitions or develop strategic alliances that will strengthen the Company's
ability to supply its products on a global basis.
 
    MODULAR PRODUCT OPPORTUNITIES.  The Company has capitalized on the
system/modular sourcing trend among OEMs by offering customers higher
value-added supply capabilities through an increasing focus on the production of
assemblies consisting of multiple component parts that are welded or otherwise
fastened together by the Company. The APC Acquisition will significantly expand
the Company's ability to supply OEMs with modules consisting of integrated
assemblies and component parts that can be installed as a unit in a vehicle at
the OEM assembly plant.
 
    INCREASE VEHICLE PENETRATION.  The Company has developed strong
relationships with certain OEM engineering and purchasing personnel which allow
it to identify business opportunities and to react to customer needs in the
early stages of vehicle design. The Company believes that these relationships
give it a competitive advantage over smaller and less capable suppliers in
marketing its broad range of products and in developing new product concepts,
such as expanded use of modules, that complement its existing product lines.
 
    PURSUIT OF "WORLD CAR" OPPORTUNITIES.  The Company has been working closely
with certain customers on the development of "world cars," which are designed by
OEMs in one vehicle center to a single global standard but produced and sold in
different geographic markets. Suppliers for a specific "world car" are often
required to provide their products on a worldwide basis. The Company believes
that it has a competitive advantage in potentially supplying certain world cars
given its international presence, full-service capabilities and existing
position as a leading supplier on the Ford Escort and DEW98 luxury car, as well
as on other existing vehicle platforms which may eventually evolve into world
cars.
 
THE APC ACQUISITION
 
    APC is a leading designer and producer of structural and suspension
components for the automotive, light truck and heavy truck markets. APC's
products include light truck frames, automotive engine cradles, suspension and
other components and heavy truck frame rails. In 1996, over 70% of APC's
revenues was derived from the sale of structural components for light trucks and
sport utility vehicles, a growing segment of the North American automotive
market. APC's customers include the three major North American OEMs as well as
certain Transplants, including Toyota, Nissan, Isuzu and Honda. APC's three
largest customers, Ford, General Motors and Chrysler, accounted for
approximately 46%, 23% and 20%, respectively, of APC's revenues in 1996.
Approximately 11% of APC's revenues in 1996 was derived from the production of
heavy truck frame rails for North American heavy truck OEMs. The Company
believes APC is the largest supplier in this segment, with a market share of
approximately 51% in 1996. APC
 
                                       33
<PAGE>
conducts its operations through 15 facilities which, when added to the Company's
existing 19 facilities, will result in a total of over seven million square feet
of manufacturing floor space.
 
    The Company believes that the APC Acquisition will provide the Company with
several strategic benefits, including the following:
 
   
    EXPANDED PRODUCT OFFERINGS AND MODULAR PRODUCT OPPORTUNITIES.  The APC
Acquisition will significantly expand the Company's product offerings by adding
lower body structural components to the Company's existing line of upper body
structural components. In addition, APC's products provide an ideal platform for
developing modular product offerings for the Company's customers. APC's frame
and engine cradle products can be combined with a number of the Company's
existing product offerings, including control arms, suspension components,
exhaust hanger assemblies and spring towers and hangers to deliver more complete
systems or modules to its OEM customers at a lower overall cost. The APC
Acquisition will enable the Company to produce a larger portion of a vehicle,
which the Company believes will afford it significant opportunities to increase
revenues as OEMs continue to consolidate their supplier base.
    
 
    INCREASED CUSTOMER PENETRATION.  The APC Acquisition will significantly
expand the Company's penetration within each of the three major North American
OEMs. Following the APC Acquisition, the Company believes it will be the largest
supplier of structural components to Chrysler, the largest supplier of metal
components to Ford and a major supplier of structural components to General
Motors. The APC Acquisition will also expand the Company's penetration within
certain Transplants by doubling the Company's sales to Toyota, expanding its
already significant position at Honda, increasing sales to Nissan and adding
Isuzu as a new customer.
 
   
    INCREASED PENETRATION IN LIGHT TRUCK SEGMENT AND OTHER KEY MODELS.  The APC
Acquisition will increase the Company's North American content per vehicle from
$26.74 in 1996 to $77.49 on a pro forma basis and will triple the Company's
content per vehicle in the expanding light truck/sport utility market segment,
which segment represented approximately 60% of the Company's pro forma revenues
for 1996. The APC Acquisition will increase the Company's content per vehicle on
key light truck/sport utility vehicles such as the Ford Explorer and Ranger and
the Chrysler Dakota, Durango and Ram as well as on high volume passenger cars
such as the Ford Taurus/Sable and the Chrysler Intrepid/Concorde/Vision. The
Company believes that this increased model penetration will afford it greater
opportunities to supply additional parts and modules for such models.
    
 
    COMPLEMENTARY NEW TECHNOLOGY.  The APC Acquisition will provide the Company
with a variety of new and enhanced design and manufacturing process technology,
including APC's patented three piece side rail frame and patented Simulform-TM-
forming technology, the latter of which may result in cost savings and quality
improvements over conventional stamping technology in certain specialized
applications. In addition, APC's existing hydroforming technology complements
the Company's initiatives in this area. The APC Acquisition will also provide
the Company with additional painting, coating and welding technologies and
advanced logistical parts management systems. The Company believes that these
acquired technologies will provide significant additional opportunities to serve
existing customers and obtain new business.
 
   
    OPERATIONAL EFFICIENCIES.  The APC Acquisition will provide the Company with
a number of opportunities to reduce costs and improve operational efficiency.
For example, APC currently outsources many of its stamping needs, some of which
will be able to be supplied by the Company's existing stamping facilities. In
addition, the Company's and APC's facilities are geographically located in such
a way as to allow the Company to optimize its management and logistical
capabilities on a regional basis. APC's facilities are strategically located
close to many of its and the Company's major customers, allowing for inventory
and freight cost-savings. The increased size of the Company may also improve the
Company's ability to negotiate more favorable terms on its purchasing and supply
contracts, as well as achieve other operational cost savings.

<PAGE>
    EXPANDED GLOBAL CAPABILITIES.  OEMs are increasingly demanding that their
suppliers have global production capabilities. APC's presence in China, Japan
and South America complements the Company's current European initiatives to
provide expanded global production capabilities for both North American and
international OEMs. See "--Global Initiatives."
 
PRODUCTS
 
    GENERAL.  The Company's current products consist of a broad array of
stamped, formed, welded and assembled metal components, many of which are
critical to the structural integrity of a vehicle. As a result of the APC
Acquisition, the Company will expand its product offerings and will be able to
manufacture and supply its customers with, among other products, light truck
frames, automotive engine cradles, trailing axles and heavy truck frame rails.
These additional products will complement the Company's existing base of
products, many of which are currently attached directly to the frame of a
vehicle at the OEM assembly plant. Following the APC Acquisition, the Company's
products will generally include structural components, suspension components and
engineered assemblies.
 
    STRUCTURAL COMPONENTS.  The Company's current structural component products
form the basic upper body structure of the vehicle and include large metal
stampings such as body pillars, roofrails, side sills, parcel shelves and
intrusion beams. APC's structural component products form the basic lower body
structure of the vehicle and include light truck frames, automotive engine
cradles and heavy truck frame rails. Critical to the strength and safety of
vehicles, structural products carry the load of the vehicle and provide crash
integrity.
 
    SUSPENSION COMPONENTS.  The Company's current suspension component products
include stamped, formed and welded products such as control arms, suspension
links, track bars and spring/shock towers. APC's suspension components include
control arms, suspension links and trailing axles. Critical to the ride,
handling and noise characteristics of a vehicle, suspension components are a
natural extension of the Company's larger structural components.
 
    ENGINEERED ASSEMBLIES.  The Company's current engineered assemblies include
a broad array of highly engineered parts such as hood and deck lid hinges, brake
components and fuel filler assemblies. Such engineered assemblies are a natural
extension to the Company's other products in that they are attached to both
structural and suspension components. The APC Acquisition will not add
materially to the Company's existing array of engineered assembly products.
 
    OTHER.  In addition to the Company's and APC's structural, suspension and
mechanical component products, each of the Company and APC manufactures a
variety of other products, including heat shields and other precision stampings,
for their OEM customers.

    Although a portion of the Company's products are sold directly to OEMs as
finished products, most are used by the Company to produce assemblies consisting
of multiple parts that are welded or otherwise
fastened together by the Company. Systems and assemblies currently produced by
the Company include front and rear structural suspension systems comprised of
control arms, suspension links and axle assemblies consisting of stamped metal
trailing axles, assembled brake shoes, hoses and tie rods. As a result of the
APC Acquisition, the Company will significantly expand its ability to supply
OEMs with systems and modules consisting of integrated assemblies and component
parts that can be installed as a unit in a vehicle at the OEM assembly plant.
 
CUSTOMERS AND MARKETING
 
    The North American automotive market is dominated by General Motors, Ford
and Chrysler, with Transplants representing approximately 20% of this market in
1996. The Company currently supplies its products primarily to Ford, Chrysler,
Honda, General Motors, Toyota, Nissan and Mazda. The APC Acquisition will
significantly expand the Company's penetration within each of the three major
North American OEMs. In addition, the APC Acquisition will also expand the
Company's penetration with certain Transplants, including doubling the Company's
sales to Toyota, expanding its already significant position at Honda, increasing
sales to Nissan and adding Isuzu as a new customer. APC sells its heavy truck
products primarily to Ford, Freightliner Corporation, PACCAR Inc., Volvo/GM
Heavy Truck Corp. and Navistar International Corp.

    OEMs typically award contracts that cover parts to be supplied for a
particular car model. Such contracts range from one year to over the life of the
model, which is generally three to seven years and do not require the purchase
by the customer of any minimum number of parts. The Company and APC also compete
for new business to supply parts for successor models and therefore are subject
to the risk that the OEM will not select the Company to produce parts on a
successor model. The Company and APC supply parts for a broad cross-section of
both new and mature models, thereby reducing their reliance on any particular
model. For example, the Company supplies parts for substantially all models
produced by Ford, Honda and Chrysler and APC currently supplies Chrysler with
substantially all of its full frame requirements.

    Most of the parts the Company and APC produce have a lead time of two to
five years from product development to production. See "--Design and Engineering
Support." Since 1988, the Company has been the leading supplier for hood and
deck hinges at Ford and Chrysler and is responsible for the design and
production of such products. The selling prices of these products are generally
negotiated between the Company and its customers and are typically not subject
to a competitive bid process. APC is currently the largest supplier of
structural components to Chrysler.

    Sales of the Company's and APC's products to OEMs are made directly by their
respective sales and engineering forces, each headquartered in their respective
technical centers located in Farmington Hills, Michigan. Through their technical
centers, the Company and APC service their OEM customers and manage their
continuing programs of product design improvement and development. The Company
and APC each periodically place engineering staff at various customer facilities
to facilitate the development of
 
                                       37
<PAGE>
new programs. After the APC Acquisition, the Company's sales and engineering
force will consist of approximately 460 individuals.
 
DESIGN AND ENGINEERING SUPPORT
 
    The Company strives to maintain a technological advantage through investment
in product development and advanced engineering capabilities. The Company's
manufacturing engineering capabilities enable it to design and build
high-quality and efficient manufacturing systems, processes and equipment and to
continually improve its production processes and equipment. The Company's
manufacturing engineers are located at each of its manufacturing facilities.
 
    As a result of the APC Acquisition, the Company's engineering staff will
increase from approximately 140 to approximately 400 full-time engineers, whose
responsibilities range from research and development, advanced product
development, product design, testing and initial prototype development to the
design and implementation of manufacturing processes.
 
    Because assembled parts must be designed at an early stage in the
development of new vehicles or model revisions, the Company is increasingly
given the opportunity to utilize its product engineering resources early in the
planning process. Advanced development engineering resources create original
engineering designs, computer-aided designs, feasibility studies, working
prototypes and testing programs to meet customer specifications. The Company's
advanced development capabilities have resulted in several innovations in hinge
design that have provided significant benefits to the Company's customers. The
Company also has full service design capability for chassis components. APC has
a long history of developing innovative new designs both to improve the quality
and to lower the cost of its designs. Recent innovations include the patented
three piece side rail, the use of aluminum and other alternative material
applications in its structural components and the use of high-performance
alternative coatings for its structural components, including epoxy coated
primer, two-coat water-reducible coatings, ultrasolids and hybrid coatings.
 
GLOBAL INITIATIVES
 
    The Company has formed, or is in the process of forming, strategic alliances
with other suppliers throughout the world, including in Europe, Asia and Latin
America. The Company has recently opened a European sales and engineering office
to service its U.K. and German OEM customers. In addition, the Company has a
joint manufacturing and marketing agreement with Kirchhoff, a German automobile
parts supplier, pursuant to which the Company and Kirchhoff have agreed to
provide manufacturing and marketing services to each other when and as required
by each company's OEM customers. A current focus of the Company's acquisition
strategy is to acquire European suppliers, which would provide the Company with
a manufacturing presence in Europe and afford the Company access to new customer
opportunities.
 
    The APC Acquisition will significantly expand the Company's global
initiatives. In addition to a Japanese sales office, APC has a 60% ownership
interest in a joint venture located in Changchun, China, which will manufacture
automobile parts for Volkswagen A.G. APC also has a Brazilian subsidiary, which
will be supplying frame components for the Dodge Dakota and has a manufacturing
arrangement to provide cross beams for the Ford Fiesta. Prior to entering into
negotiations with APC, the Company had been investigating the possibility of
opening a sales office in Japan and acquiring an interest in a Brazilian
operation.
 
MANUFACTURING
 
    After the APC Acquisition, the Company's manufacturing operations will
consist primarily of stamping operations, system and modular assembly
operations, roll-forming and hydroforming operations and associated coating and
other ancillary operations. The APC Acquisition will provide the Company with
significant additional stamping and assembly capacity.
 
                                       38
<PAGE>
    Stamping involves passing metal through dies in a stamping press to form the
metal into three-dimensional parts. The Company produces stamped parts using
over 240 precision single-stage, progressive and transfer presses, ranging in
size from 150 to 2,000 tons, which perform multiple functions as raw material
proceeds through the press and is converted into a finished product. The Company
continually invests in its press technology to increase flexibility, improve
safety and minimize die changeover time. The APC Acquisition will broaden the
Company's stamping capabilities by adding over 400 stamping presses ranging from
200 to 4,000 tons in size.
 
    After forming is completed, stampings that are to be used in assemblies are
placed in work-in-progress staging areas from which they are fed into
cell-oriented assembly operations that produce complex, value-added assemblies
through the combination of multiple parts that are welded or fastened together.
The Company's assembly operations are performed on either dedicated, high-volume
welding/fastening machines or on flexible-cell oriented robotic lines for units
with lower volume production runs. The assembly machines attach additional
parts, fixtures or stampings to the original metal stampings. In addition to
standard production capabilities, the Company's assembly machines are also able
to perform various statistical control functions and identify improper welds and
attachments. The Company continually works with manufacturers of fixed/robotic
welding systems to develop faster, more flexible machinery. Several of the
Company's welding systems were designed by the Company.
 
    APC's manufacturing and assembly processes are state-of-the-art. Using
highly-automated assembly processes, APC's new Plymouth, Michigan light truck
frame assembly facility requires no changeover time between the six frame models
it assembles for Chrysler's new Dodge Dakota. Line programmable controllers
adjust assembly equipment to accommodate various frame wheelbase configurations
at various stages of assembly, while robotic welding and material handling
processes are responsible for 99 percent of the facility's frame welding. In
comparison, conventional light truck frame assembly requires equipment and tool
reconfiguration to accommodate various frame models. APC's patented
Simulform-TM- forming process, currently being tested for production use,
simultaneously forms, pierces and joins components of an engine cradle assembly,
resulting in cost savings over traditional stamping techniques, due to a
reduction in the number of presses and operators required and the enhanced
quality and lighter weight of the products manufactured through this method. In
addition, APC's solid state welding capabilities allow it to weld at lower
temperatures which results in less structural distortion of products,
exceptional weld quality and higher production rates than conventional welding
processes. APC also utilizes a significant number of robots in its frame
riveting processes and automated transfer systems in addition to their use in
welding operations.
 
    The products manufactured by the Company and APC use various grades and
thicknesses of steel and aluminum, including hot and cold rolled, galvanized,
organically coated, stainless and aluminized steel. Neither the Company nor APC
produces exposed sheet metal components, such as exterior body panels. See
"--Suppliers and Raw Materials."
 
    OEMs have established quality rating systems involving rigorous inspections
of suppliers' facilities and operations. OEMs' factory rating programs provide a
quantitative measure of a company's success in improving the quality of its
operations. The Company and APC have each received quality awards from Ford (Q1)
and Chrysler (Pentastar) and the Company has consistently received one of Ford's
highest commercial ratings for suppliers in the stamping segment. The automotive
industry has recently adopted a quality rating system known as QS-9000. The
Company has recently received QS-9000 certification and APC expects to receive
such certification by the end of 1997.
 
COMPETITION
 
    The Company operates in a highly competitive, fragmented market segment of
the automotive supply industry, with a limited number of competitors generating
revenues in excess of $200 million. The number of the Company's competitors has
decreased in recent years and is expected to continue to decrease due to the
supplier consolidation resulting from changing OEM policies. The Company's
largest competitors include The Budd Company, a subsidiary of Thyssen AG
("Budd"), Magna International Inc. ("Magna"),
 
                                       39
<PAGE>
Midway Products Corp., Modern Tool & Die Co., L&W Engineering and divisions of
OEMs with internal stamping and assembly operations, all of which have
substantial financial resources. The Company competes with Magna across most of
the Company's product lines, and with its other significant competitors in
various segments of its product lines. For example, the Company competes with
Budd for large stampings, while it competes with ITT Automotive for hinge
business. Aetna Industries, Active Tool & Die Co., AG Simpson, Lobdell-Emory
Mfg. Co. and L&W Engineering compete with the Company for medium-size structural
stampings.
 
    APC also operates in a highly competitive market segment that is
significantly less fragmented than the Company's market segment. APC's principal
competitors include Dana Corporation, Magna and internal divisions of OEMs, all
of which are large and have substantial resources. APC also competes with
Midland Corporation across its heavy truck product lines.
 
    The Company and APC principally compete for new business both at the
beginning of the development of new models and upon the redesign of existing
models. New model development generally begins two to five years before the
marketing of such models to the public. Once a producer has been designated to
supply parts for a new program, an OEM usually will continue to purchase those
parts from the designated producer for the life of the program, although not
necessarily for a redesign. Competitive factors in the market for the Company's
and APC's products include product quality and reliability, cost and timely
delivery, technical expertise and development capability, new product innovation
and customer service.
 
SUPPLIERS AND RAW MATERIALS
 
    The primary raw material used to produce the majority of the Company's
products is steel. The Company purchases hot and cold rolled, galvanized,
organically coated, stainless and aluminized steel from a variety of suppliers.
The Company employs just-in-time manufacturing and sourcing systems enabling it
to meet customer requirements for faster deliveries while minimizing its need to
carry significant inventory levels. The Company has not experienced any
significant shortages of raw materials and normally does not carry inventories
of raw materials or finished products in excess of those reasonably required to
meet production and shipping schedules. Raw materials costs represented
approximately 53% of the Company's revenues in 1996, and steel represented
approximately 70% to 75% of raw material costs in 1996.
 
    Honda and Chrysler currently purchase all of the steel used by the Company
for their models directly from steel producers. Ford is in the process of
implementing a similar program. As a result, the Company will have minimal
exposure to changes in steel prices for parts supplied to Ford, Honda and
Chrysler, which collectively represented 86% of the Company's revenues in 1996.
APC currently purchases substantially all of the steel used in its manufacturing
operations from steel manufacturers, either directly or through distributors.
The Company expects that APC will adopt a similar arrangement with such
customers following the APC Acquisition.
 
    The Company expects that the content level of metal in cars and light trucks
will remain constant or increase slightly due to the trend toward increased
vehicle size and a greater emphasis on metal recycling. Although the search for
improved fuel economy and weight reduction has resulted in attempts to reduce
the sheet metal content of light vehicles, an efficient, cost-effective
substitute for steel used in the Company's structural products has not been
found. While various polymers have been used recently for fenders, hoods and
decks, such products do not have the inherent strength or structural integrity
on a cost-effective basis to be used for structural components. The Company and
APC are involved in ongoing evaluations of the potential for the use of aluminum
and of specialty steel in their products.
 
    Other raw materials purchased by the Company include dies, fasteners,
tubing, springs, rivets and rubber products, all of which are available from
numerous sources. APC currently outsources many of its stamping needs, some of
which can be supplied by the Company's existing stamping facilities.

FACILITIES
 
    The Company maintains several manufacturing facilities located in close
proximity to many of the high-volume vehicle assembly plants in the United
States. In addition, APC has located its facilities close to its major OEM
customers in order to facilitate the just-in-time delivery requirements of its
customers and to minimize freight delivery costs. The Company's and APC's
facilities are geographically located in such a way as to enable the Company to
optimize their management and logistical capabilities on a regional basis.
 
    The following table provides information regarding the Company's and APC's
principal facilities:

(1) Facility is subject to an IRB financing arrangement pursuant to which the
    Company or APC makes periodic lease payments and has the option to acquire
    such facility for nominal consideration at the end of the term.
 
(2) Facility is leased by a joint venture in which APC holds a 60% equity
    interest.
 
    Management believes that substantially all of the Company's and APC's
property and equipment is in good condition. In order to increase efficiency,
the Company expects to make capital expenditures for equipment upgrades at the
facilities recently acquired in the MSTI Acquisition. See "Management's
Discussion and Analysis of Results of Operations and Financial
Condition--Liquidity and Capital Resources."
 
    The Company believes that its existing facilities will be adequate to meet
its production demands for the foreseeable future. The Company's facilities were
specifically designed for the manufacturing of the
 
                                       41
<PAGE>
Company's products. The utilization and capacity of such facilities are
dependent upon the mix of products being produced by the Company.
 
EMPLOYEES
 
   
    The Company currently has approximately 2,900 employees, of whom
approximately 1,100 are covered under collective bargaining agreements, one of
which expires in July 1997. The Company currently anticipates that it will enter
into a new collective bargaining agreement prior to the expiration of such
agreement. The remaining collective bargaining agreements expire in 1999. The
Company believes that its future success will depend in part on its ability to
continue to recruit, retain and motivate qualified personnel at all levels of
the Company. The Company has instituted a large number of employee programs to
increase employee morale and expand the employees' participation in the
Company's business. The Company has not experienced any work stoppages and
considers its relations with its employees to be good.
    
 
    APC currently has approximately 5,300 employees, of whom approximately 2,900
are covered under several collective bargaining agreements, the earliest of
which expires in September 1998. The Company believes APC's relations with its
employees are generally good. The Company expects to retain APC's employees on
substantially the same terms and conditions of employment as were in place prior
to the APC Acquisition.
 
ENVIRONMENTAL MATTERS
 
    The Company believes it conducts its operations in substantial compliance
with applicable environmental and occupational health and safety laws. The
Company does not expect to incur material capital expenditures for environmental
compliance during its current or succeeding fiscal year. However, as is the case
with manufacturers in general, if a release of hazardous substances occurs on or
from the Company's properties or at any associated offsite disposal location, if
contamination from prior activities is discovered at any of the Company's
properties or if non-compliance with environmental regulations or permits is
discovered, the Company may be held liable and the amount of such liability
could be material. In connection with the Trylon and MSTI Acquisitions,
MascoTech has agreed to indemnify the Company for certain environmental matters,
including replacement of underground storage tanks at the Traverse City
facilities and any remediation that may be required at the Kendallville
facility.
 
    In connection with the APC Acquisition, A.O. Smith has agreed, subject to
certain limitations, to indemnify the Company for environmental matters relating
to APC arising from events occurring, or conditions arising, prior to the date
of the APC Acquisition. This indemnification obligation applies to claims to the
extent exceeding $250,000 submitted by the Company within three years of the
acquisition date. To the extent that such claims exceed $5.0 million in the
aggregate, A.O. Smith will indemnify 70% of such losses, up to A.O. Smith's
maximum $75.0 million indemnification obligation under the purchase agreement.
In addition, A.O. Smith has agreed to retain certain environmental liabilities
for, among other things, liabilities arising from offsite disposal of hazardous
substances prior to the APC Acquisition.
 
LEGAL PROCEEDINGS
 
   
    The Company is not currently involved in any material lawsuits. The Company
believes it maintains adequate insurance, including product liability coverage.
The Company historically has not been required to pay any material liability
claims. APC is subject to a number of outstanding lawsuits arising in the
ordinary course of its business. A.O. Smith has agreed, however, to retain
responsibility for all material lawsuits relating to APC and to indemnify the
Company for any losses it may incur in connection with such lawsuits.
    
 
   
    A.O. Smith is a party to a lawsuit alleging, among other things, that APC
misappropriated trade secrets from one of its competitors in developing certain
techniques used in a hydroforming process being developed by APC. In connection
with the APC Acquisition, A.O. Smith has retained the liability relating to this
litigation and has agreed to indemnify the Company for any monetary damages it
may incur as a result of such litigation. A.O. Smith has informed the Company
that it believes this suit to be without merit and is asserting various defenses
to such allegations. The hydroforming process currently being used by APC is not
the subject of this lawsuit. As a result, the Company does not currently believe
that its ability to utilize APC's hydroforming technology will be materially
impaired even if A.O. Smith is found liable in such suit.

    order for Onex to realign its ownership interest in the Company. As a

    of the Offering, Onex is expected to have beneficial ownership of 500,000

(2) The partners of J2R are S. A. Johnson, Scott D. Rued, W. H. Clement, Robert
    R. Hibbs, Mary L. Johnson and Carl E. Nelson.
 
    Set forth below are the material relationships which existed between the
Company and the Selling Stockholders during the last three years:
 
   
    The Company, Onex and certain stockholders, including J2R and its partners,
are parties to a registration agreement pursuant to which the Company has
granted such stockholders rights to register their shares of Common Stock.
Pursuant to the terms of such agreement, the Company will pay all expenses of
the Offering attributable to the Selling Stockholders other than underwriting
discounts and commissions that may be incurred by them.
    
 
   
    The Company, Onex, J2R and its partners and certain other investors, who
collectively own 2,310,836 shares of Common Stock (prior to the Offering), are
parties to an Investor Stockholders Agreement pursuant to which each party has
agreed to vote his or its shares in the same manner that Onex votes its shares
of Common Stock. In addition, certain members of management, who collectively
own 753,284 shares of Common Stock, have executed irrevocable proxies that grant
Onex the right to vote such shares on all matters presented to the Company's
stockholders for a vote. These voting arrangements will terminate upon
completion of the Offering.
    
 
   
    In 1994, Hidden Creek, a partnership affiliated with Onex and J2R, received
$333,000 for providing strategic direction, management and financial services to
the Company. In addition, in 1994 the Company paid Hidden Creek an aggregate of
$500,000 for services rendered in connection with the acquisitions of Edgewood
and Kalamazoo. In 1996, the Company paid Hidden Creek an aggregate of $750,000
for services in connection with the acquisitions of Trylon and MSTI. The Company
expects to pay Hidden Creek an aggregate of $1,250,000 for services rendered in
connection with the APC Acquisition.
    
 
    In May 1994, Onex acquired 788,831 shares of Common Stock for aggregate
consideration of $2,543,599 and J2R acquired 197,207 shares of Common Stock for
aggregate consideration of $4,176. Onex and J2R are parties to a Co-Investment
Agreement pursuant to which they have agreed to an allocation of the purchase
price of their investments. As a result of this allocation, the combined price
per share paid by Onex and J2R in connection with the purchase of the
above-described shares is the same price per share paid by all other
stockholders acquiring shares at such time.

                      DESCRIPTION OF NEW CREDIT AGREEMENT
 
   
    In connection with the APC Acquisition, the Company's principal operating
subsidiary expects to enter into the New Credit Agreement. Proceeds from
borrowings under the New Credit Agreement will be used to (i) pay a portion of
the cash purchase price of the APC Acquisition; (ii) redeem the Senior Notes;
and (iii) pay transaction fees and expenses associated with the APC Acquisition.
In the event that this Offering has not been completed at the time of the
consummation of the APC Acquisition, the Company will finance the entire APC
Acquisition with the proceeds from borrowings under the New Credit Agreement.
The Company anticipates that the New Credit Agreement will provide for a six
year revolving credit facility of up to $750 million, with a letter of credit
sublimit of $100 million and an alternative currency facility sublimit of $55
million. In addition, an additional loan of up to $200 million will be made
available to the Company in the event the APC Acquisition is consummated prior
to the receipt of the proceeds of the Offering. This loan would have a term of
18 months and would be fully repaid from the proceeds of the Offering. The
following description of the material terms of the New Credit Agreement is
qualified in its entirety by reference to the executed letter agreement relating
to the New Credit Agreement, which has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part.
    
 
   
    Indebtedness under the New Credit Agreement will be guaranteed by the
Company and certain of its subsidiaries (with exceptions for foreign
subsidiaries to be mutually agreed upon).
    
 
   
    The loans under the New Credit Agreement will bear interest at a rate per
annum equal to, at the Company's option, (i) the Base Rate or (ii) the reserve
adjusted LIBOR Rate plus a margin ranging from 17 to 50 basis points, depending
upon the ratio of the consolidated indebtedness of the Company to stockholders'
investment. Adjustments to the margin set forth above will be made according to
the pricing matrix that will be attached to the New Credit Agreement.
    
 
   
    The New Credit Agreement will require the Company to meet certain financial
tests, including but not limited to minimum interest coverage, minimum
debt/capital and maximum leverage ratio. The New Credit Agreement will also
contain covenants which, among other things, will limit (i) the incurrence of
additional indebtedness and contingent obligations; (ii) the creation of liens
and encumbrances; (iii) the payment of dividends; (iv) additional investments;
(v) prepayments of other indebtedness; (vi) asset sales, acquisitions, joint
ventures, mergers and consolidations; (vii) transactions with affiliates; and
(viii) other matters customarily restricted in such agreements.
    
 
    The New Credit Agreement will contain customary events of default including
but not limited to (i) payment defaults; (ii) breach of representations and
warranties; (iii) noncompliance with covenants; (iv) bankruptcy; (v) judgments
in excess of specified amounts; (vi) failure of any guaranty or security
agreement supporting the New Credit Agreement to be in full force and effect;
(vii) defaults under other instruments or agreements of indebtedness; and (viii)
a Change of Control (as such term will be defined in the New Credit Agreement).

    The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of the Common Stock
offered hereby are subject to approval of certain legal matters by counsel and
to certain other conditions. The Underwriters are obligated to take and pay for
all the shares of the Common Stock if any are taken.
 
   
    The Company has been advised that the Underwriters propose to offer the
shares of the Common Stock in part directly to the public initially at the
public offering price set forth on the cover page of this Prospectus and in part
to certain dealers at such price less a concession not in excess of $.  per
share; that the Underwriters may allow, and such dealers may reallow, a
concession not in excess of $.  per share on sales to other dealers; and that
after the public offering, the public offering price and other selling terms may
be changed by the Underwriters. The Underwriters have informed the Company that
they do not intend to confirm sales to any accounts over which they exercise
discretionary authority.
    
 
    The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
1,513,500 additional shares of Common Stock at the price to the public less
underwriting discounts and commissions. The Underwriters may exercise such
option only for the purpose of covering over-allotments, if any, incurred in
connection with the sales of Common Stock offered hereby. To the extent that the
Underwriters exercise such option, each Underwriter will become obligated,
subject to certain conditions, to purchase the same percentage of such
additional shares as the number of other shares to be purchased by that
Underwriter bears to the total number of shares set forth on the cover page of
this Prospectus.
 
    The Company, its Directors and executive officers, the Selling Stockholders
and certain other stockholders have agreed with the Underwriters not to offer,
sell, contract to sell, grant any other option to purchase or otherwise dispose
of any shares of the Common Stock or any securities convertible into or
exercisable for, or warrants, rights or options to acquire, shares of Common
Stock for a period of 90 days without the prior written consent of DLJ, other
than sales of Common Stock under the Underwriting Agreement, the issuance of
shares of Common Stock upon the exercise of outstanding options and certain
transfers to affiliates.
 
   
    At the request of the Company, the Underwriters have reserved up to 500,000
shares of Common Stock for sale at the public offering price to OMI. The number
of shares of Common Stock available to the general public will be reduced to the
extent OMI purchases any of the reserved shares. Any reserved shares of Common
Stock that are not so purchased by OMI at the closing of the Offering will be
offered by the Underwriters to the general public on the same terms as the other
shares in the Offering.

    The Company, its principal operating subsidiaries and the Selling
Stockholders have agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that they may be required to make in respect thereof.
 
   
    In connection with the Offering, the Underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the Common Stock.
Specifically, the Underwriters may overallot the Offering, creating a syndicate
short position. Underwriters may bid for and purchase shares of Common Stock in
the open market to cover syndicate short positions. In addition, the
Underwriters may bid for and purchase shares of Common Stock in the open market
to stabilize the price of the Common Stock. These activities may stabilize or
maintain the market price of the Common Stock above independent market levels.

these activities at any time.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Tower Automotive, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Tower
Automotive, Inc. (a Delaware corporation) and Subsidiaries as of December 31,
1995 and 1996, and the related consolidated statements of operations,
stockholders' investment and cash flows for each of the three years in the
period ended December 31, 1996. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Tower
Automotive, Inc. and Subsidiaries as of December 31, 1995 and 1996, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1996 in conformity with generally accepted
accounting principles.

</TABLE>
 
    CUSTOMER TOOLING AND OTHER DESIGN COSTS:
 
    Customer tooling represents costs incurred by the Company in the development
of new tooling used in the manufacture of the Company's products. Once customer
approval is obtained for the manufacture of a new product, the Company is
reimbursed by its customers for the cost of certain of the tooling, at which
time the tooling becomes the property of the customers.
 
    In addition, the Company has certain other tooling and design costs related
to previously proven product designs which are reimbursed by the Company's
customers as the related product is sold through an incremental increase in each
product's unit selling price. Such costs are capitalized and amortized using the
unit of production method over the life of the related tool. Amounts capitalized
and included in other assets were $3.8 million at December 31, 1995 and $3.7
million at December 31, 1996. If the Company forecasts that the amount of
capitalized tooling and design costs exceeds the amount to be realized through
the sale of product, a loss is recognized currently.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment acquired in the acquisitions discussed in Note
3 was recorded at its fair value, determined based on appraisals, as of the
respective acquisition dates. Additions to property, plant and equipment
following the acquisitions are stated at cost. For financial reporting purposes,
depreciation and amortization are provided using the straight-line method over
the following estimated useful lives:
 
<TABLE>
<S>                                                            <C>
                                                                 15 to 30
Buildings and improvements...................................      years
Machinery and equipment......................................  3 to 20 years
</TABLE>
 
    Accelerated depreciation methods are used for tax reporting purposes.
 
    Start-up costs related to major facilities and new platforms are capitalized
and amortized over the life of the related platform, generally five years. The
unamortized start-up cost balance was $876,000 at December 31, 1995 and
$1,011,000 at December 31, 1996.
 
    Interest is capitalized during the construction of major facilities and is
amortized over the related estimated useful lives. Interest costs of $1,157,000
were capitalized during the year ended December 31, 1995. No interest was
capitalized during the year ended December 31, 1996.
 
    Maintenance and repairs are charged to expense as incurred. Major
betterments and improvements which extend the useful life of the related item
are capitalized and depreciated. The cost and accumulated depreciation of
property, plant and equipment retired or otherwise disposed of are removed from
the related accounts, and any residual values are charged or credited to income.
 
    OTHER ASSETS:
 
    Goodwill represents the excess of the purchase price over the fair value of
the net assets acquired and is being amortized on a straight-line basis over 40
years. Debt issue costs are amortized on a straight-line basis over the term of
the related obligations.
 
    The Company periodically evaluates whether events and circumstances have
occurred which may affect the estimated useful life or the recoverability of the
remaining balance of its goodwill and other long-lived assets. If such events or
circumstances were to indicate that the carrying amount of these assets were not
recoverable, the Company would estimate the future cash flows expected to result
from the use of the assets and their eventual disposition. If the sum of the
expected future cash flows (undiscounted and without interest charges) were less
than the carrying amount of goodwill, the Company would recognize an impairment
loss.
 
   
    FAIR VALUE OF FINANCIAL INSTRUMENTS:
    
 
   
    The carrying amounts of the Company's borrowings under the outstanding
industrial development revenue bonds approximates fair value as the floating
rates applicable to these financial instruments reflect changes in the overall
market interest rates. The carrying amount of the Company's outstanding series A
and series B senior notes also approximate fair value as interest rates have not
changed materially since their issuance in May 1996.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
   
    REVENUE RECOGNITION:
    
 
   
    The Company recognizes revenue as its products are shipped to its customers.
    
 
    INCOME TAXES:
 
    The Company accounts for income taxes under the liability method, whereby
deferred income taxes are recognized at currently enacted income tax rates to
reflect the tax effect of temporary differences between the financial reporting
and tax bases of assets and liabilities.
 
    NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE:
 
    Net income per common and common equivalent share is computed by dividing
net income applicable to common stockholders by the weighted average number of
common and common stock equivalent shares outstanding during each period
presented. Common stock issued and common stock options granted within one year
immediately preceding the initial public offering of common stock (Common Stock)
discussed in Note 4 at prices below the public offering price have been
reflected in the net income per share calculation as if they had been
outstanding for all periods presented. Net income for purposes of computing net
income per common and common equivalent share reflects the elimination of
interest expense on the convertible subordinated notes, net of the related
income tax benefit.
 
   
    STOCK OPTIONS:
    
 
   
    The Company accounts for stock options under the provisions of APB No. 25,
under which no compensation expense is recognized when the stock options are
granted. The pro forma effects had the Company followed the provisions of SFAS
No. 123 are included in Note 4.
    
 
    USE OF ESTIMATES:
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. The ultimate results could differ from those estimates.
 
3. ACQUISITIONS:
 
    On May 4, 1994, the Company acquired the operating assets and assumed
certain operating liabilities and indebtedness of Edgewood Tool and
Manufacturing Company (Edgewood), a manufacturer of hood and deck lid hinges and
structural metal components for the automotive industry, for total consideration
of $24.6 million in cash and assumed indebtedness and the issuance of $5.0
million of Convertible Subordinated Notes. In addition, the Company entered into
a five year employment agreement with Edgewood's former president and issued an
option to acquire 102,984 shares of Common Stock at an exercise price of $6.55
per share.
 
    On June 29, 1994, the Company acquired the capital stock of Kalamazoo
Stamping and Die Company (Kalamazoo), a supplier of structural metal stampings
and assemblies for the automotive industry, for net consideration of
approximately $12.3 million in cash.

3. ACQUISITIONS: (CONTINUED)
    On January 16, 1996, the Company acquired all of the outstanding common
stock of Trylon Corporation (Trylon) for total consideration of approximately
$25 million. The acquisition was financed with the proceeds of a $25 million
term loan. Trylon manufactures metal stampings and assemblies for the North
American automotive industry from four facilities in Traverse City, Michigan.
 
   
    On May 31, 1996, the Company acquired all of the outstanding common stock of
MascoTech Stamping Technologies, Inc. (MSTI), a wholly owned subsidiary of
MascoTech, Inc. (MascoTech). Consideration consisted of $55 million in cash,
785,000 shares of the Company's Common Stock and warrants to acquire 200,000
shares of the Company's Common Stock at an exercise price of $18 per share. The
Company may also make additional payments of up to $30 million to MascoTech if
certain operating targets are achieved by the MSTI facilities in the first three
years following the acquisition. The amounts to be paid to MascoTech are equal
to two times the amount by which operating profit, as defined, of the MSTI
facilities exceeds $24 million each year. Based on results of operations of the
MSTI facilities through December 31, 1996, no contingent payments are due.
Contingent consideration paid in future periods, if any, will be recorded as
additional goodwill. MSTI manufactures metal chassis and suspension components
and assemblies for the North American automotive industry from facilities in
Ohio, Indiana and Michigan.
    
 
   
    These acquisitions have been accounted for using the purchase method of
accounting and, accordingly, the assets acquired and liabilities assumed have
been recorded at fair value as of the dates of the acquisitions. The assets and
liabilities of Trylon and MSTI have been recorded based upon preliminary
estimates of fair value as of the dates of acquisition. The Company does not
believe the final allocations of the purchase price will be materially different
than the preliminary allocations. The excess of the purchase price over the fair
value of the assets acquired and liabilities assumed has been recorded as
goodwill. Results of operations for these acquisitions have been included in the
accompanying consolidated financial statements since the dates of acquisition.
The accompanying unaudited consolidated pro forma results of operations for the
years ended December 31, 1995 and 1996 give effect to the 1996 Offering (as
defined in Note 4) and the acquisitions of Trylon and MSTI as if they were
completed at the beginning of the respective periods. The unaudited pro forma
financial information does not purport to represent what the Company's results
of operations would actually have been if such transactions in fact had occurred
at such date or to project the Company's results of future operations (in
thousands, except per share data):

4. STOCKHOLDERS' INVESTMENT:
 
    PUBLIC OFFERINGS OF COMMON STOCK:
 
    In August 1994, the Company completed an initial public offering, including
shares issued pursuant to the underwriters' over-allotment option, of 4,887,500
shares of its Common Stock at $11.50 per share resulting in net proceeds to the
Company of approximately $51.3 million.
 
    During 1996, the Company completed an offering of 2,232,900 shares of its
Common Stock at an offering price of $24.50 per share (the 1996 Offering)
resulting in net proceeds of approximately $51.3 million. Proceeds from the 1996
Offering were used by the Company to retire borrowings under its secured credit
agreement and for general corporate purposes.
 
    PRIVATE PLACEMENTS:
 
    During 1993, the Company sold 522,640 shares of its Common Stock to certain
employees for aggregate proceeds of approximately $981,000. Approximately
$434,000 of this amount was financed through notes to the Company which bear
interest at prime plus 1% (9.5% at December 31, 1995 and 9.25% at December 31,
1996) and are due in 1998. These notes are reflected as a reduction of
stockholders' investment in the accompanying consolidated financial statements.
Approximately $248,000 and $330,000 of these notes had been collected as of
December 31, 1995 and 1996.
 
    As a component of the financing for the acquisition of Edgewood in May 1994
(See Note 3), the existing stockholders and members of the Company's management
participated in a $4.1 million private placement of 1,585,365 shares of Common
Stock, resulting in net cash proceeds to the Company of $3.7 million.
Approximately $404,000 of this amount was financed through notes to the Company
which bear interest at prime plus 1% and are due in 1999. These notes are
reflected as a reduction of stockholders' investment in the accompanying
consolidated financial statements. Approximately $93,000 and $333,000 of these
notes had been collected as of December 31, 1995 and 1996.
 
    STOCK OPTION PLAN:
 
    The Company sponsors the 1994 Key Employee Stock Option Plan (the Stock
Option Plan), under which any person who is a full-time, salaried employee of
the Company (excluding non-management directors) is eligible to participate in
the Stock Option Plan (an Employee Participant). A committee of the board of
directors selects the Employee Participants and determines the terms and
conditions of the options. The Stock Option Plan provides for the issuance of
options up to 500,000 shares of Common Stock at exercise prices equal to the
stock market price on the date of grant to Employee Participants,

    As of December 31, 1996, the outstanding stock options granted in 1995 have
a remaining contractual life of approximately 8.5 years and the outstanding
stock options granted in 1996 have a remaining contractual life of approximately
9.5 years.
    
 
    INDEPENDENT DIRECTOR STOCK OPTION PLAN:
 
    In February 1996, the Company's board of directors approved the Tower
Automotive, Inc. Independent Director Stock Option Plan (the Director Option
Plan) that provides for the issuance of options to Independent Directors, as
defined, to acquire up to 100,000 shares of the Company's Common Stock, subject
to certain adjustments reflecting changes in the Company's capitalization. The
option exercise price must be at least equal to the fair value of the Common
Stock at the time the option is issued. Vesting is determined by the Board of
Directors at the date of grant and in no event can be less than six months from
the date of grant. As of December 31, 1996, the Company had granted stock
options under this plan to acquire 22,500 shares of Common Stock at an exercise
price of $15.125 per share. None of these director options were exercisable or
vested at December 31, 1996.
 
    EMPLOYEE STOCK PURCHASE PLAN:
 
    The Company also sponsors an employee stock discount purchase plan which
provides for the sale of up to 500,000 shares of the Company's Common Stock at
discounted purchase prices, subject to certain limitations. The cost per share
under this plan is 85% of the market value of the Company's Common Stock at the
date of purchase, as defined. During the year ended December 31, 1995, 4,143
shares of Common Stock were issued to employees pursuant to this plan and during
the year ended December 31, 1996, 18,350 shares of Common Stock were issued. The
weighted average fair value of shares sold in 1995 and 1996 were $8.11 and
$14.32, respectively.
 
    STOCK-BASED COMPENSATION PLANS:
 
    As discussed above, the Company has two stock option plans, the Stock Option
Plan and the Independent Director Stock Option Plan, and an Employee Stock
Purchase Plan. The Company accounts

for these plans under APB Opinion No. 25, under which no compensation cost has
been recognized. Had compensation cost for these plans been determined
consistent with Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation," (SFAS No. 123), the Company's pro forma net
income and pro forma earnings per share would have been as follows (in
thousands):

    Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years. The
effect of the stock offered under the Employee Stock Purchase Plan was not
material for 1995 and 1996.
 
    The fair value of each option grant is estimated on the date of the grant
using the Black-Scholes option pricing model with the following weighted average
assumptions: risk free interest rates of 6.5%, 6.9% and 6.93% in 1995 and 5.57%
in 1996; expected life of seven years for 1995 and 1996; expected volatility of
35%, 37% and 41% in 1995 and 56% in 1996.
 
    OTHER COMMON STOCK EQUIVALENTS:
 
    In connection with the acquisition of Edgewood in May 1994, the Company
issued an option to acquire 102,984 shares of Common Stock at an exercise price
of $6.55 per share. The options expire in 2004. As of December 31, 1996, 34,328
options were vested and exercisable.
 
    In connection with the acquisition of MSTI in May 1996, the Company issued
warrants to MascoTech to acquire 200,000 shares of Common Stock at an exercise
price of $18 per share. The warrants expire in 2006.
 
   
    DIVIDENDS:
    
 
   
    The Company has not declared or paid any cash dividends in the past, as
discussed in Note 5, the Company's debt agreements restrict the amount of
dividends the Company can declare or pay. As of December 31, 1996, under the
most restrictive debt covenants, the Company could not have paid any cash
dividends.

revenue bonds. Available credit under this agreement is limited to eligible
accounts receivable and inventories, as defined, which exceeded $75 million at
December 31, 1996. The weighted average interest rate for borrowings under the
revolving credit facility was 7.4% for the year ended December 31, 1995 and 6.1%
for the year ended December 31, 1996. In connection with the transaction
described in Note 10, the Company obtained a commitment from a bank to refinance
the existing Credit Agreement.
 
    The Company financed the cash portion of the MSTI acquisition through the
issuance in two series of Senior Notes having an aggregate principal amount of
$65 million. The Senior Notes require the Company to make semi-annual interest
payments commencing December 1, 1996, while principal is payable in varying
annual installments beginning in 2000. Net proceeds from the sale of the Senior
Notes in excess of the amounts used to finance the cash portion of the MSTI
acquisition, together with borrowings under the revolving credit facility, were
used to repay in full the remaining balance outstanding on a $25 million term
loan incurred by the Company in connection with the acquisition of Trylon.
 
    In connection with the acquisition of Edgewood in May 1994, the Company
issued the $5.0 million Convertible Subordinated Notes, which generally are
convertible at any time into 823,874 shares of Common Stock. The Convertible
Subordinated Notes are subject to prepayment in the event of, and become
convertible upon, a sale of the Company and are subordinated to all other debt
of the Company which is not expressly subordinated to the Convertible
Subordinated Notes. As of December 31, 1996, approximately $2.5 million of these
notes had been converted into 410,529 shares of Common Stock.
 
    In June 1994 and March 1995, the Company issued $25.0 million and $20.0
million, respectively, of industrial development revenue bonds related to the
construction and equipping of a manufacturing facility in Bardstown, Kentucky.
The bonds are collateralized by letters of credit. The facility will be
completed in two phases. The undispersed proceeds from these bonds are invested
in treasury securities and reflected as restricted cash in the accompanying
consolidated balance sheets. The Company also has approximately $2.9 million in
outstanding indebtedness relating to industrial development revenue bonds issued
in connection with the construction of its Auburn, Indiana plant. The bonds are
collateralized by a letter of credit, certain equipment and a mortgage on this
plant.
 
    The debt agreements described above contain various restrictive covenants
which, among other matters, require the Company to maintain certain financial
ratios. The agreements also limit additional indebtedness, capital expenditures
and cash dividends. The Company was in compliance with all debt covenants as of
December 31, 1995 and 1996.

    The Company had salary continuation agreements with three employees which
provided for certain payments beginning with the later of retirement or
attainment of age 62, or in the event of death or disability. During 1995 two of
these employees received payments totaling $529,000 as a result of their
retirement. The expense under this plan has not historically been significant.
The Company's total obligation under these agreements was $318,000 as of
December 31, 1995 and $334,000 as of December 31, 1996 and was included in
noncurrent liabilities in the accompanying consolidated balance sheets.
 
    POSTRETIREMENT PLANS:
 
    The Company provides certain medical insurance benefits for retired
employees. Certain employees of the Company are eligible for these benefits if
they remain employed until age 55 or 59 and fulfill other eligibility
requirements specified by the plans. Certain retirees between the ages of 55 and
62 must contribute 100% of the group rate for active employees. No contributions
are required for retirees 62 or older. Benefits are continued for dependents of
eligible retiree participants after the death of the retiree.

    The projected postretirement benefit obligation is calculated using a 7.5%
annual rate of increase in per capita claims cost in 1995 and 7.0% in 1996. This
rate is assumed to decrease by one half of one percent per year through 1997. In
1998, the rate is assumed to be 6.5% and remain at that level for all years
thereafter.
 
    If the health care cost trend rate were increased one percentage point, the
accumulated postretirement benefit obligation and the aggregate of the service
and interest cost discussed above would have increased by 12%.

    The Company has made payments to Hidden Creek Industries, an affiliate of
the Company, for certain acquisition related and other management services
totaling $833,000 during 1994 and $750,000 during 1996.
 
10. AGREEMENT TO ACQUIRE AUTOMOTIVE PRODUCTS COMPANY:
 
    On January 27, 1997, the Company entered into an agreement to acquire and
assume substantially all of the assets and liabilities of the Automotive
Products Company (APC), a division of A.O. Smith Corporation, for $625 million
in cash, subject to certain adjustments. APC, which had revenues of
approximately $860 million for the year ended December 31, 1996, designs and
manufactures frames, frame components, engine cradles, suspension components and
modules for the North American automotive and heavy truck industries. This
acquisition is expected to close during the second quarter of 1997. This
acquisition will be accounted for as a purchase and, accordingly, APC's assets
and liabilities will be recorded at fair value as of the acquisition date, with
any excess purchase price recorded as goodwill.
 
   
    In connection with this acquisition, the Company agreed to enter into a new
credit facility with a bank, which will provide a total financing availability
of up to $865 million. The specific terms of the new credit facility are
currently being negotiated with the bank. The new credit facility will also
include certain restrictive covenants, which the Company expects will be similar
in nature to those in its existing credit agreement. This facility will become
effective contemporaneously with the completion of the acquisition discussed
above.
    
 
    As part of this refinancing, the Company expects a portion of the proceeds
from the new credit facility will be used to retire the Senior Notes discussed
in Note 5. If the Senior Notes are retired, the Company will record an
extraordinary loss of approximately $3 million, net of income taxes, related to
prepayment penalties and the write-off of previously capitalized deferred
financing costs.
 
    On February 18, 1997, the Company filed a registration statement on Form S-3
with the Securities and Exchange Commission related to the proposed sale of up
to 8,500,000 shares of the Company's Common Stock to the public. The Company
expects this offering will be completed early in the second quarter of 1997.
Proceeds from this offering will be used to fund a portion of the purchase price
related to the acquisition discussed above.
 
   
    The acquisition of APC will be accounted for as a purchase and, accordingly,
APC's assets and liabilities will be recorded at fair values as of the
acquisition date. Following is an unaudited pro forma balance sheet of the
Company, based on preliminary estimates of the allocation of the purchase price,
as if

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To A.O. Smith Corporation:
 
    We have audited the accompanying combined statements of net assets to be
acquired of the Automotive Products Company (a division of A.O. Smith
Corporation--a Delaware corporation) as of December 31, 1995 and 1996, and the
related combined statements of revenues and expenses and cash flows for each of
the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    These financial statements have been prepared to reflect the operations of
A.O. Smith Corporation to be acquired pursuant to the transaction discussed in
Note 1 and are not intended to be a complete presentation of A.O. Smith
Corporation's assets and liabilities, revenues and expenses or cash flows.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets to be acquired of the Automotive
Products Company pursuant to the Asset Purchase Agreement discussed in Note 1 as
of December 31, 1995 and 1996, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1996 in
conformity with generally accepted accounting principles.

    Prepaid customer tooling represents costs incurred by the Company in the
development of new tooling used in the manufacture of the Company's products
over the amount of such costs billed to the Company's customers. The Company
receives specific purchase orders for this tooling and is reimbursed by its
customers. Costs incurred are deferred until reimbursed by the customer.
 
    PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment are stated at cost. For financial reporting
purposes, depreciation and amortization are provided using the straight-line
method over the following estimated useful lives:
 
<TABLE>
<S>                                                            <C>
                                                               10 to 40
Buildings and improvements...................................  years
Machinery and equipment......................................  5 to 17 years
</TABLE>
 
    Accelerated depreciation methods are used for tax reporting purposes.
 
    Interest of $0.7 million, $0.4 million and $1.7 million was capitalized to
fixed assets under construction during 1994, 1995 and 1996.
 
    Maintenance and repairs are charged to expense as incurred. Major
improvements which extend the useful life of the related item are capitalized
and depreciated. The cost and accumulated depreciation of property, plant and
equipment retired or otherwise disposed of are removed from the related
accounts, and any residual values are charged or credited to income.
 
    CAPITALIZED SOFTWARE COSTS:
 
    Incremental direct costs associated with the customization and
implementation of purchased software are expensed until the Company is
reasonably certain that the specific new system (or substantial revision) will
be completed and will fulfill its intended use. Such costs are then capitalized
and amortized over their estimated useful lives--generally 3 to 10 years.
Training and nonincremental costs incurred in these activities are expensed as
incurred. Unamortized computer software costs were $6.9 million and $16.0
million as of December 31, 1995 and 1996. Amortization of these costs which was
charged to expense amounted to $1.6 million, $0.6 million and $0.7 million
during 1994, 1995 and 1996.

</TABLE>
 
    REVENUE RECOGNITION:
 
    The Company recognizes revenue upon shipment of product to the customer.
 
    FOREIGN CURRENCY TRANSLATION:
 
    For all subsidiaries outside the United States, the Company uses the local
currency as the functional currency. For these operations, assets and
liabilities are translated to U.S. dollars at year-end exchange rates and
weighted average exchange rates are used for revenues and expenses. The
resulting translation adjustments are reflected as a change in the Parent's
investment in the Company. Gains and losses from foreign currency transactions
are included in results of operations.
 
    DERIVATIVES:
 
    As a result of having various foreign operations, the Parent and Company are
exposed to the effect of foreign currency rate fluctuations on the U.S. dollar
value of their foreign operations. Further, the Parent and Company conduct
business in various foreign currencies. To minimize the effect of fluctuating
foreign currencies on its operating results, the Parent has historically entered
into foreign currency forward contracts. The contracts were used to hedge known
foreign currency transactions for both the Parent and the Company on a
continuing basis for periods consistent with the Parent's exposures. The effect
of such transactions as they related to the Company was not material.
 
    INCOME TAXES:
 
    The accompanying financial statements reflect income taxes accounted for
under the liability method, whereby deferred income taxes are recognized at
currently enacted income tax rates to reflect the tax effect of temporary
differences between the financial reporting and tax bases of certain assets and
liabilities.
 
    CHARGES FROM A.O. SMITH:
 
    The Parent has historically provided various services to APC and its other
operating units, including income tax, internal audit, benefits, corporate
technology, legal, strategic and treasury related services. Specific
determination of the costs associated with these services that relate directly
to the Company is not practicable; accordingly, the amounts presented in the
accompanying financial statements related to these

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
services reflect estimates, which management believes were reasonable and
appropriate in the circumstances. Management does not believe that such
estimates differ materially from actual amounts had it been practicable to
specifically identify such actual amounts. The estimated amount of corporate
expenses included in the accompanying combined statements of revenues and
expenses for the years ended December 31, 1994, 1995 and 1996 was $6 million,
$6.5 million and $5 million.
 
    In addition to the above expense reimbursement charges, the accompanying
financial statements reflect charges for the Company's proportionate share of
the Parent's interest expense, allocated based on the relationship of the
Company's net assets to the Parent's total consolidated net assets.
 
    NEW ACCOUNTING PRONOUNCEMENT:
 
    During 1996, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." This statement provides
guidance for determining whether the value of certain long-lived assets,
identifiable intangibles and goodwill has been impaired. The adoption of this
statement had no impact on the Company's financial position or results of
operations.
 
    USE OF ESTIMATES:
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Such estimates relate primarily to the carrying amounts of
inventories and customer tooling balances and to the determination of charges
for services provided by the Parent. The ultimate results could differ from
those estimates.
 
3. MAJOR CUSTOMERS:
 
    The Company sells its products directly to automobile manufacturers.
Following is a summary of customers that accounted for a significant portion of
the Company's revenues:

    Receivables from these customers represented 68% and 76% of net accounts
receivable at December 31, 1995 and 1996.
 
4. SALES TO METALSA:
 
    APC sells certain automotive frame components to Metalsa S.A. de C.V., a
Mexican joint venture in which the Parent is an investor. Sales were $11.0
million in 1994, $11.6 million in 1995 and $15.7 million in

1996. Receivables related to the transaction activity were $.8 million, and $1.0
million as of December 31, 1995 and 1996. Such transactions were priced to
approximate fair market value.
 
5. INVESTMENT IN JOINT VENTURE:
 
    In 1995, APC entered into a joint venture to produce certain of its parts in
China. This investment, equal to 60% of the joint venture equity, is accounted
for using the equity method of accounting as a result of the Company's voting
rights and general business restrictions within China. At December 31, 1995 and
1996, the carrying amount of the investment was $3.8 million and $20.6 million
and is included in other assets in the accompanying combined statements of net
assets to be acquired. The carrying amounts of the investment have not exceeded
the Company's equity in the underlying net assets. No income or distributions
were recognized or paid out by the joint venture in 1995 or 1996. Facility
operations are scheduled to begin in early 1997.
 
6. INCOME TAXES:
 
    The Company's results of operations have been historically included in the
consolidated federal income tax returns of A.O. Smith. As a result, all tax
payments were made by A.O. Smith. The provisions for income taxes in the
accompanying combined statements of revenues and expenses for the years ended
December 31, 1994, 1995 and 1996 were computed as if the Company had filed
separate tax returns.
 
    The income tax provision consisted of the following (in thousands):

7. COMMITMENTS AND CONTINGENCIES:
 
    RETIREMENT AND BENEFIT PLANS:
 
    Employees of the Company may be eligible to participate in a variety of
retirement and benefit plans that are sponsored by the Company and the Parent.
Participation in these plans is subject to certain eligibility conditions.
 
    The Parent sponsors a qualified noncontributory defined benefit plan which
was established on December 31, 1995 through the merger of its various defined
benefit plans in the United States into one plan. Benefits for salaried
employees are based on the employee's years of service and compensation.
Benefits for hourly employees are generally based on years of service. The
Parent's policy is to contribute amounts which are actuarially determined to
provide sufficient assets to meet future benefit payment requirements consistent
with the funding requirements of federal law and regulations. Plan assets
consist primarily of marketable equities and debt securities. The Company
recognized pension expense of $3.0 million, $5.4 million and $3.3 million during
1994, 1995 and 1996 related to its contributions to this plan. As of December
31, 1996, net plan assets exceeded the projected benefit obligation under the
plan.
 
    The Parent sponsors several defined contribution employee benefit plans for
hourly and salaried personnel in the United States and Canada. Under the plans,
the Company matches employee contributions based upon formulas established in

after January 1, 1996, will be subject to a maximum annual benefit limit.
Salaried employees hired after December 31, 1993, are not eligible for
postretirement medical benefits.

    The assumed healthcare cost trend rate used in measuring the APBO is 6
percent. The weighted average discount rate used in determining the APBO was 7.5
and 8.0 percent at December 31, 1995 and 1996. If the healthcare cost trend rate
were increased by 1 percent, the APBO at December 31, 1996 would increase by
$1.8 million and net periodic postretirement benefit cost for 1996 would
increase $.2 million.

8. ACQUISITION BY TOWER AUTOMOTIVE, INC.:
 
    On January 27, 1997, a wholly owned subsidiary of R.J. Tower agreed to
acquire and assume substantially all of the assets and liabilities of the
Company. Terms of the agreement provided for the payment of cash consideration
of approximately $625 million, subject to certain adjustments. The Acquisition
is expected to be completed during the second quarter of 1997. Subsequent to the
Acquisition, the operations of the Company will be continued by R.J. Tower on a
basis substantially consistent with that which existed prior to the Acquisition.
The Acquisition will be accounted for as a purchase and, accordingly, the
Company's assets and liabilities will be recorded at fair value as of the
acquisition date.

ITEM 17.  UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be the initial bona fide offering thereof.
 
    (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    (c) The undersigned Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be a part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For purposes of determining any liability under the Securities Act,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

     generated or used on or prior to the Closing Date by Sellers or any of

     referred to as "OFFSITE LIABILITIES"); provided, however, that any

          1.6. NONASSIGNABLE CONTRACTS AND RIGHTS.  Notwithstanding anything to
the contrary in this Agreement, no Contracts, properties, rights or other assets
of the Sellers shall be deemed sold, transferred or assigned to Buyer pursuant
to this Agreement if the attempted sale, transfer or assignment thereof to Buyer
without the consent or approval of another party or governmental entity would be
ineffective or would constitute a breach of Contract or a violation of any law
or regulation or would in any other way materially and adversely affect the
rights of the Sellers (or Buyer as transferee or assignee) and such consent or
approval is not obtained on or prior to the Closing Date.  In such case, to the
extent possible, (i) the beneficial interest in or to such Contracts,
properties, rights or other assets (collectively, the "BENEFICIAL RIGHTS") shall
in any event pass as of the Closing Date to Buyer under this Agreement; and (ii)
pending such consent or approval, Buyer shall assume or discharge the
Liabilities of the Sellers under such Beneficial Rights (to the extent such
obligations are Assumed Liabilities) as agent for the Sellers, and the Sellers
shall act as Buyer's agent in the receipt of any benefits, rights or interest
received from the Beneficial Rights.  Buyer and the Sellers shall use their
reasonable best efforts (and bear their respective costs of such efforts)
without payment of any material penalty, fee or any other amounts to any third
parties, subject to SECTION 9.2, to obtain and secure any and all consents and
approvals that may be necessary to effect the legal and valid sale, transfer or
assignment of the Contracts, properties, rights or other assets underlying the
Beneficial Rights, including without limitation their formal assignment or
novation, if advisable.  Buyer and the Sellers will make or complete such
transfers as soon as reasonably possible and cooperate with each other in any
other reasonable arrangement designed to provide for Buyer the Beneficial Rights
including enforcement at the cost and for the account of Buyer of any and all
rights of the Sellers, or either one of them, against the other party thereto
arising out of the breach or cancellation thereof by such other party or
otherwise, and to provide for the discharge by Buyer and Parents, jointly and
severally, of any Liability under such Contracts, properties, rights or other
assets, to the extent such Liability constitutes an Assumed Liability.  With
respect to any Contracts, properties, rights or other assets referred to above
that are not assigned to Buyer because of the failure to obtain a required
consent ("NONTRANSFERRED ASSETS"), Buyer and Parents, jointly and severally,
shall indemnify, defend and hold harmless the Sellers from and against any
Liability that the Sellers may have in connection with such Nontransferred
Assets as a result of the transactions contemplated by this Agreement, except to
the extent of the Sellers' gross negligence or willful malfeasance.

     2.   CLOSING; PAYMENT OF PURCHASE PRICE AT CLOSING AND CLOSING ADJUSTMENT

          2.1. CLOSING DATE.  Unless this Agreement shall have been terminated
and the transactions herein contemplated shall have been abandoned pursuant to
SECTION 7.1, and provided that the conditions to the Closing set forth in
SECTION 5.1 and SECTION 5.2 are satisfied or waived, the closing with respect to
the transactions provided for in this Agreement (the "CLOSING") shall take place
at the offices of Foley & Lardner, 777 East Wisconsin Avenue, Milwaukee,
Wisconsin, at 10:00 a.m., Milwaukee time, on the earliest of (a) April 20, 1997;
(b) the fifth business day after the latest of (i) the satisfaction or waiver of
the conditions to the Closing set forth in SECTION 5.1(C) and SECTION 5.2(C),
(ii) the date the Company, in its sole discretion, delivers a notice to Buyer to
commence the time period described in this CLAUSE (b)(II) (the "CLOSING NOTICE")

be agreed upon by the Sellers 


                                       -9-

<PAGE>

and Buyer.  Notwithstanding the foregoing, if the Closing does not take place in
accordance with the preceding sentence because any condition to the obligations
of the Sellers, on the one hand, or Buyer, on the other hand, under this
Agreement is not met on that date, then either party may postpone the Closing
from time to time to any designated subsequent business day not more than five
(5) business days after the original or postponed date on which the Closing was
to occur by delivering notice of such postponement on the date the Closing was
to occur.  The actual time and date of the Closing are herein called the
"CLOSING DATE".   All acts and transactions occurring under this Agreement at
the Closing shall be effective as of 11:59 p.m., Milwaukee time, on the Closing
Date (the "EFFECTIVE TIME").

          2.2. PURCHASE PRICE AND PAYMENT.  In consideration for the Assets, and
subject to the terms and conditions of this Agreement, Buyer shall on the
Closing Date (a) assume the Assumed Liabilities as provided in SECTION 1.4 and
(b) transfer cash to the Company in the amount of $625,000,000, subject to the
following adjustments:

          (i)  INCREASE.  An increase equal to the amount, if any, by which
     the Net Book Value (as defined in SECTION 2.3(A)) as reflected on the
     Estimated Closing Statement (as defined in SECTION 2.3(B)) is greater
     than $411,500,000; and

          (ii) DECREASE.  A reduction equal to the amount, if any, by which
     the Net Book Value as reflected on the Estimated Closing Statement is
     less than $411,500,000

(the amounts paid by Buyer pursuant to SECTIONS 2.2(A) AND (B) are hereinafter
collectively referred to as the "INITIAL PURCHASE PRICE").  The amount of the
Initial Purchase Price payable pursuant to SECTION 2.2(B) shall be paid on the
Closing Date by wire transfer of immediately available funds to an account the
Company has designated, at least two (2) business days prior to the Closing
Date, in writing to Buyer.  The value tendered by Buyer pursuant to this
SECTION 2.2, as adjusted pursuant to the provisions of Section 2.3, shall be
hereinafter referred to as the "PURCHASE PRICE."

          2.3. DETERMINATION OF NET BOOK VALUE; POST-CLOSING ADJUSTMENT.

          (a)  NET BOOK VALUE.  The term "NET BOOK VALUE" shall mean the
     total book value, as of the Effective Time, of the Assets less the
     total book value of the Assumed Liabilities, in each case as reflected
     on the Estimated Closing Statement, the Closing Statement or the
     Adjusted Closing Statement, as the case may be; provided, that (i) Net
     Book Value shall not include the value of any Asset where neither the
     Asset nor its Beneficial Rights is actually transferred to Buyer
     (including without limitation any Receivable that has been assigned or
     purported to be assigned to Norwest Bank Minnesota, National
     Association), (ii) in the event the equity interests in any Division
     Affiliate are not actually transferred, Net Book Value shall not
     include the value of any assets held by such Division Affiliate and
     (iii) Net Book Value shall not reflect any Liability that is not an
     Assumed Liability or any reserve therefor.


                                      -10-

          (b)  ESTIMATED CLOSING STATEMENT.  For purposes of determining an
     estimate of the Net Book Value to be reflected on the Closing
     Statement and the Purchase Price payable by Buyer at the Closing, not
     less than five (5) business days prior to the Closing Date, the
     Company shall, in consultation with Buyer, prepare and deliver to
     Buyer a balance sheet which shall represent the Company's reasonable
     estimate of the Closing Statement; such balance sheet to be in
     accordance with GAAP, and to the extent in accordance with GAAP, using
     accounting principles and policies, consistent with the balance sheet
     of the Division as of December 31, 1996, attached hereto as part of
     SCHEDULE 3.1(D) (the "PRELIMINARY STATEMENT"), except that such
     balance sheet shall reflect only the Assets and the Assumed
     Liabilities.  In the event Buyer shall object to any of the
     information set forth on such balance sheet or accompanying schedules
     as presented by the Company, the parties shall negotiate in good faith
     and attempt to agree on appropriate adjustments such that such balance
     sheet and accompanying schedules reflect a reasonable estimate of the
     Closing Statement and of the Net Book Value to be reflected on the
     Closing Statement, but in the absence of such agreement, the most
     recent month-end balance sheet of the Division shall control (the
     estimated balance sheet as agreed to by the parties pursuant to this
     subsection, or in the absence of such agreement, the most recent
     month-end balance sheet of the Division, is herein referred to as the
     "ESTIMATED CLOSING STATEMENT").  In connection with the determination
     of the Estimated Closing Statement, the Company shall provide to Buyer
     such information and detail and access to such books, records and work
     papers as Buyer shall reasonably request.

          (c)  CLOSING STATEMENT.  Within fifteen (15) days following the
     Closing, the Company shall prepare, or cause to be prepared, and
     deliver to Buyer an unaudited statement (the "CLOSING STATEMENT")
     which shall set forth the Net Book Value as of the Effective Time and,
     except as set forth on SCHEDULE 2.3(c), shall be prepared (i) in
     accordance with generally accepted accounting principles in the United
     States ("GAAP"), as in effect on the date of such preparation, (ii) in
     a manner involving application of GAAP and otherwise consistent with
     the preparation of the Preliminary Statement as to accounting methods,
     policies, practices and procedures, with consistent classifications,
     judgments and estimation methodologies to the extent such methods,
     policies, practices and procedures are in accordance with GAAP, and
     (iii) based only on the information relating to the content of the
     Closing Statement that is known to Buyer or the Company on the date 30
     days after the Closing Date.  The parties agree that the adjustment
     contemplated by this SECTION 2.3(c) is solely intended to show changes
     in the Assets and the Assumed Liabilities reflected in the Preliminary
     Statement to the Effective Time and that any such change can only be
     measured if the Closing Statement is prepared using the same
     principles, methods, policies, practices and procedures (subject to
     the immediately preceding sentence) as were used in connection with
     the preparation of the Preliminary Statement provided that such
     principles, methods, policies, practices and procedures are in
     accordance with 


                                      -11-

<PAGE>

     GAAP.  In preparing the Closing Statement, the respective amounts included
     therein for reserves (in the form of an accrued Liability or an offset to
     an Asset or similar item) relating to any of the Assets or the Assumed
     Liabilities, the amount of which was determined for the Preliminary
     Statement by subjective estimates, shall be equal to the respective amounts
     (including the absence of a reserve or zero) included in respect of such
     items on the Preliminary Statement except to reflect (A) changes in
     circumstances or events (including changes to reserves to reflect costs
     incurred or payments made by or on behalf of the Sellers) occurring between
     the date of the Preliminary Statement and the Closing Date to the knowledge
     of Buyer and the Sellers on the date 30 days after the Closing Date or (B)
     changes occurring between the date of the Preliminary Statement and the
     date 30 days after the Closing Date in information known to Buyer and the
     Sellers on the Closing Date concerning circumstances or events occurring
     prior to the date of the Preliminary Statement (in which event the first
     sentence of this SECTION 2.3(C) shall govern the determination of any
     changes in the reserve).

          (d)  DISPUTES REGARDING CLOSING STATEMENT.  Buyer shall, within
     thirty (30) days after the delivery by the Company of the Closing
     Statement, complete its review of the Net Book Value derived from the
     Closing Statement.  If Buyer determines that the Closing Statement has
     not been prepared in accordance with SECTION 2.3(C), then Buyer shall
     inform the Company on or before the last day of such 30-day period by
     delivering a notice to the Company ("BUYER'S OBJECTION") (i) setting
     forth a specific description of the basis of Buyer's Objection and the
     adjustments to Net Book Value that Buyer believes should be made and
     (ii) only including objections based on mathematical errors or based
     on the Closing Statement not being prepared in accordance with
     SECTION 2.3(C).  The Company shall then have thirty (30) days to
     review and respond to Buyer's Objection.  The Sellers and Buyer shall
     seek in good faith to resolve in writing any differences which they
     may have with respect to any matter specified in Buyer's Objection and
     the Sellers shall have full access to the working papers of Buyer
     prepared in connection with Buyer's preparation of Buyer's Objection. 
     If the Company and Buyer are unable to resolve all of their
     disagreements with respect to the determination of the foregoing items
     within twenty (20) days following the completion of the Company's
     review of Buyer's Objection, then the Company and Buyer shall refer
     their remaining differences to Price Waterhouse, LLP or another
     internationally recognized firm of independent public accountants as
     to which the Company and Buyer mutually agree (the "CPA FIRM"), who
     shall, acting as experts and not as arbitrators, determine on the
     basis of the standards set forth in SECTION 2.3(C), and only with
     respect to the remaining accounting-related differences so submitted
     by Buyer to the Company (and not by independent review), whether and
     to what extent, if any, Net Book Value as derived from the Closing
     Statement requires adjustment.  In connection with the engagement of
     the CPA Firm, each of the parties shall execute reasonable engagement
     letters with the CPA Firm.  The Company and Buyer shall direct the CPA
     Firm to use its 


                                      -12-

<PAGE>

     reasonable best efforts to render its determination within forty-five (45)
     days.  The CPA Firm's determination shall be conclusive and binding upon
     Buyer and the Sellers.  The fees and disbursements of the CPA Firm shall be
     shared equally by Buyer and the Company.  Buyer and the Sellers shall make
     readily available to the CPA Firm all relevant books and records and any
     work papers (including those of the parties' respective accountants)
     relating to the Preliminary Statement and the Closing Statement and all
     other items reasonably requested by the CPA Firm.  The "ADJUSTED CLOSING
     STATEMENT" shall be (i) the Closing Statement in the event that (x) no
     Buyer's Objection is delivered to the Company during the 30-day period
     specified above, or (y) the Company and Buyer so agree, (ii) the Closing
     Statement, adjusted in accordance with Buyer's Objection in the event that
     the Company does not respond to Buyer's Objection within the 30-day period
     following receipt by the Company of Buyer's Objection, or (iii) the Closing
     Statement, as adjusted by either (x) the agreement of the Company and Buyer
     or (y) the CPA Firm.

          (e)  COOPERATION.  Buyer and the Company agree that, following
     the Closing, neither will take any actions with respect to the
     accounting books, records, policies and procedures of the Division
     that would obstruct or prevent the preparation of the Closing
     Statement.  Buyer shall cooperate with the Company in the preparation
     of the Closing Statement including, but not limited to, (i) providing
     the Company and the Company's representatives with full access during
     normal business hours to the books, records (including work papers,
     schedules, memoranda and other documents), facilities and employees of
     the Business, (ii) causing employees of the Business to provide the
     Company as promptly as practicable following the Closing Date (but in
     no event later than ten (10) days after the Closing Date) with normal
     year-end closing financial information for the Division for the period
     ending as of the close of business on the day immediately prior to the
     Closing Date, and (iii) cooperating fully with the Company and the
     Company's representatives, including the provision on a timely basis
     of all other information necessary or useful in connection with the
     preparation of the Closing Statement.  Buyer and its accountants shall
     have full access to all information used by the Company in preparing
     the Closing Statement, including the work papers of its accountants.

          (f)  ADJUSTMENT PAYMENT TO BUYER.  In the event the Net Book
     Value as derived from the Adjusted Closing Statement is less than the
     Net Book Value as reflected on the Estimated Closing Statement, the
     Company shall make an adjustment payment to Buyer in an amount equal
     to the difference between (i) the Net Book Value as reflected on the
     Estimated Closing Statement and (ii) the Net Book Value as derived
     from the Adjusted Closing Statement.  Any payment required by the
     first sentence of this SECTION 2.3(F) shall be made by the Company to
     Buyer, together with interest thereon at an annual rate of eight and
     one-half percent (8.5%) (the "APPLICABLE RATE") calculated on the
     basis of the number of 


                                      -13-

<PAGE>

     days elapsed from and including the Closing Date to and excluding the date
     of payment, in immediately available funds within five (5) business days
     after the determination of the Adjusted Closing Statement.

          (g)  ADJUSTMENT PAYMENT TO THE COMPANY.  In the event the Net
     Book Value as derived from the Adjusted Closing Statement is greater
     than the Net Book Value as reflected on the Estimated Closing
     Statement, Buyer shall make an adjustment payment to the Company in an
     amount equal to the difference between (i) the Net Book Value as
     reflected on the Estimated Closing Statement and (ii) the Net Book
     Value as derived from the Adjusted Closing Statement.  Any payment
     required by the first sentence of this SECTION 2.3(G) shall be made by
     Buyer to the Company, together with interest thereon at the Applicable
     Rate calculated on the basis or the number of days elapsed from and
     including the Closing Date to and excluding the date of payment, in
     immediately available funds within five (5) business days after the
     determination of the Adjusted Closing Statement.

          2.4. ALLOCATION OF PURCHASE PRICE.  The aggregate Purchase Price shall
be allocated among the Assets for tax purposes on the basis of the relative fair
market values of such properties as of the Closing Date.  The amount of the
aggregate Purchase Price allocated to the equity interests of the Company in
China JV shall be $25,000,000.  All other values, and the value of the aggregate
Purchase Price, shall be reasonably determined by Buyer and delivered to the
Company within one hundred eighty (180) days following Closing Date and shall be
subject to the Company's consent, which consent shall not be unreasonably
withheld.  The Company and Buyer will follow and use such allocation in all tax
returns, filings or other related reports made by them to any governmental
agencies.  To the extent that disclosures of this allocation are required to be
made by the parties to the Internal Revenue Service ("IRS") under the provisions
of Section 1060 of the Internal Revenue Code of 1986, as amended (the "CODE"),
or any regulations thereunder, Buyer and the Company will disclose such reports
to the other prior to filing with the IRS.

     3.   REPRESENTATIONS AND WARRANTIES

          3.1. REPRESENTATIONS AND WARRANTIES OF THE SELLERS.  To allocate risk
between the Sellers, on the one hand, and Buyer, on the other hand, for purposes
of and subject to SECTION 9.3, the Sellers, jointly and severally, represent and
warrant to Buyer as follows:

          (a)  DUE ORGANIZATION AND POWER.  The Sellers are each duly
     organized, validly existing and in good standing under the laws of the
     jurisdiction of their respective incorporation and have the requisite
     power and authority to own, lease and operate their properties to be
     sold hereunder and to conduct the Business as now conducted by them. 
     The Sellers have all requisite power and authority to enter into and
     deliver this Agreement and any other agreement contemplated hereby and
     to perform their obligations hereunder and thereunder, including the
     power and authority to convey good title to Buyer with respect to the
     Assets owned 


                                      -14-

<PAGE>

     by the Sellers.  The Sellers are duly authorized, qualified or licensed to
     do business as foreign corporations in each of the jurisdictions in which
     their right, title or interest in or to any of the Assets, or the conduct
     of the Business, requires such authorization, qualification or licensing. 
     Each of the Division Affiliates is validly existing under the laws of the
     jurisdiction of their respective incorporation.

          (b)  AUTHORIZATION AND VALIDITY OF AGREEMENT.  The execution,
     delivery and performance by each of the Sellers of this Agreement and
     any other agreements contemplated hereby and the consummation by each
     of them of the transactions contemplated hereby and thereby have been
     duly authorized by the respective boards of directors of the Sellers. 
     No other corporate or stockholder action is necessary for the
     authorization, execution, delivery and performance by the Sellers of
     this Agreement and any other agreements contemplated hereby and the
     consummation by the Sellers of the transactions contemplated hereby or
     thereby. This Agreement and the other agreements contemplated hereby
     have been, or will be at or prior to Closing, duly executed and
     delivered by each of the Sellers, and each constitutes, or will when
     so executed and delivered constitute, a valid and legally binding
     obligation of each of the Sellers, enforceable against each of them in
     accordance with its respective terms, except as enforceability may be
     limited by bankruptcy, insolvency, reorganization, moratorium and
     other similar laws relating to or affecting creditors rights generally
     or by general equitable principles (regardless of whether such
     enforceability is considered in a proceeding in equity or at law).

          (c)  NO GOVERNMENTAL APPROVALS OR NOTICES REQUIRED; NO CONFLICT
     WITH INSTRUMENTS TO WHICH THE SELLERS ARE A PARTY.  Except as
     described in SCHEDULE 3.1(C) and except for the requirement that the
     applicable waiting periods expire pursuant to the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976, as amended (the "HSR ACT"), the
     execution, delivery and performance of this Agreement and any other
     agreements contemplated hereby by the Sellers, or either one of them,
     and the consummation by each of them of the transactions contemplated
     hereby and thereby (i) will not violate (with or without the giving of
     notice or the lapse of time or both), or require any authorization,
     consent, approval, filing or notice under, any provision of any law,
     rule or regulation, court order, judgment or decree applicable to the
     Sellers or Brazil Sub, or any one of them, or applicable to any of the
     Assets and (ii) will not conflict with, or result in the breach or
     termination of any provision of, or constitute a default under, or
     result in the acceleration of the performance of the obligations of
     the Sellers or Brazil Sub, or any one of them, under, or result in the
     creation of the right to accelerate, terminate, modify or cancel, or
     result in the creation of a lien, charge or encumbrance upon a portion
     of the Assets pursuant to, or require any notice under, the charter or
     by-laws of the Sellers or Brazil Sub, or any one of them, or the
     express terms of any Contract required to be disclosed on SCHEDULE
     3.1(g) to which the Sellers or Brazil Sub, or any one of them, is a
     party or by which the 


                                      -15-

<PAGE>

     Sellers or Brazil Sub, or any one of them, or any of the Assets is bound or
     affected.  The parties hereto agree that no event, occurrence or
     circumstance that would constitute a breach of a representation or warranty
     contained in SECTION 3.2(c) will be a basis for a breach of a
     representation or warranty contained in this SECTION 3.1(c).

          (d)  FINANCIAL STATEMENTS.  SCHEDULE 3.1(D) contains certain
     historical balance sheets of the Division as of December 31, 1996,
     1995 and 1994 and statements of operations for the Division for the
     fiscal years ended December 31, 1996, 1995 and 1994 (collectively, the
     "FINANCIAL STATEMENTS").  The Financial Statements were prepared in
     accordance with GAAP, as in effect on the date of such Financial
     Statements and applied on a consistent basis during the periods
     involved (except as may be indicated in the notes or comments to such
     Financial Statements), and such Financial Statements and notes or
     comments fairly present, in all material respects, the financial
     position and results of operations of the Division as of their
     respective dates and for the respective periods covered thereby.

          the real property owned by either Seller that is used primarily

          the real property leased or subleased by either Seller that is
          used primarily by the Division;

               (iii)     except as set forth on SCHEDULE 3.1(e), there is
          no other real property used by the Division or Brazil Sub other
          than as set forth on SCHEDULE 1.1(b) and SCHEDULE 1.1(c), and to
          the knowledge of the Sellers, there is no other real property
          used by China JV except as set forth on SCHEDULE 3.1(e);

               (iv) the current use of the Facilities does not violate any
          covenant, condition, restriction or instrument of record
          affecting such Owned Real Property or, to the knowledge of the
          Sellers, Leased Real Property;

               (v)  except as set forth on SCHEDULE 3.1(e) and except for
          Permitted Encumbrances (as defined in SECTION 3.1(f)), there are
          no leases, subleases, licenses, concessions, or other agreements,
          written or oral, granting to any party or parties the right of
          use or occupancy of any portion of the Owned Real Properties or
          Leased Real Properties and there are no parties (other than
          Sellers) in possession of the Owned Real Properties or Leased
          Real Properties; and

               (vi) with respect to each lease relating to Leased Real
          Property listed on SCHEDULE 1.1(c), the Sellers have not
          assigned, transferred, conveyed, mortgaged, deeded in trust or
          encumbered any interest in the lease.

          (f)  TITLE TO PROPERTIES AND ABSENCE OF LIENS AND ENCUMBRANCES.  

               (i)  Except as set forth on SCHEDULE 3.1(f), the Sellers own all

          free and clear of all claims, covenants, conditions, restrictions,
          liens, security interests, charges, mortgages, pledges, easements,
          leases, options, rights of first refusal or offer, encumbrances,
          licenses or sublicenses, conditional sales or other title retention
          agreements (an "ENCUMBRANCE") other than Permitted Encumbrances (as
          defined below).  Upon payment for the Assets as contemplated herein,
          the Sellers will convey to Buyer all of the Sellers' right, title and
          interest in and to the Assets free and clear of all exceptions to
          title or Encumbrances, except in each case (A) as specifically set
          forth in SCHEDULE 3.1(f), (B) liens for current taxes and assessments
          not yet due and payable or being contested in good faith by
          appropriate proceedings and for which appropriate GAAP reserves have
          been made, (C) as reflected in the public records relating to real
          property included in the Assets (other than judgement or other liens
          securing financial obligations of the Sellers except those described
          in CLAUSE (B) or (D)) which do not materially impair the current use
          of the property subject thereto and (D) for contractors, materialmen
          and mechanics statutory liens incurred in the ordinary course of
          business for which amounts are not delinquent and in the aggregate do
          not materially impair the Business (such exceptions, collectively, the
          "PERMITTED ENCUMBRANCES").

               (ii) The Assets, together with the rights received under the
          Transition Services Agreement referred to in SECTION 8.7 comprise all
          of the assets and rights of the Sellers, tangible and intangible
          (including Trade Rights), that the Sellers use in the conduct of the
          Business as presently conducted, except for the assets described on
          SCHEDULE 3.1(f).

               (iii)     The Company obtained a building permit for and
          initiated construction of the Facility of the Business located in
          Botetourt County, Virginia (the "ROANOKE FACILITY") prior to
          August 1, 1996.  Taking into account the Company's investments
          prior to the date of this Agreement and investments the Division

          will have constructed the Roanoke Facility with a total

          The Sellers have delivered to, or made available for inspection

     (collectively, the "MATERIAL CONTRACTS") is valid, binding and in full
     force and effect and is enforceable by the Company, Enterprises or
     Brazil Sub, as the case may be, in accordance with its terms, and the

     Except with respect to the representations and warranties contained in
     this Agreement, Buyer is acquiring the Assets AS IS, WHERE IS. THE
     SELLERS MAKE NO OTHER REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED,
     WITH RESPECT TO THE DESIGN, CONDITION, CAPACITY, VALUE, UTILITY,
     PERFORMANCE OR QUALITY OF THE ASSETS (INCLUDING INVENTORY) AND THE
     SELLERS MAKE NO IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A

     the date of this Agreement, the Sellers have not suffered any strike,
     picketing or work stoppage by any group of Division Employees
     affecting the Business during the three (3) years preceding the date
     of this Agreement.  Except as set forth on SCHEDULE 3.1(j), there are
     no union organizing campaigns, or other questions concerning
     representation, relating to Division Employees, and there are no
     unfair labor practice charges pending or, to the knowledge of Sellers,

          transactions contemplated hereby.  The Sellers acknowledge that there
          are uncertainties inherent in Buyer's and Parents' attempting to make

          projected results in a material manner.

          (i)  CLOSING DATE.  All of the representation and warranties contained
     in this Section 3.2 will be true and correct on the Closing Date except for

acting on behalf of the Sellers, makes or has made any other express or implied
representation or warranty to Buyer or Parents as to the accuracy or
completeness of any information regarding the Business or any other matter. 
Buyer and Parents further agree that neither the Sellers nor any other person or
entity will have or be subject to any liability to Buyer or Parents, or any one
of them, or any other person resulting from the distribution to Buyer or
Parents, or Buyer's or Parents' use, of any such information, including the
Memorandum prepared by Merrill Lynch, Pierce, Fenner & Smith Incorporated in
October 1996 and any information, document or material made available to Buyer
or Parents, or any one of them, in certain "data rooms," management

the extent any such information is incorporated into this Agreement or the
Schedules hereto.

          Without limitation, in connection with Buyer's or Parents'
investigation of the Business, the Division or the Assets, Buyer and Parents
have received from or on behalf of the Sellers certain projections, including,
without limitation, projected statements of operating revenues and income from
operations of the Business for the fiscal year ending on December 31, 1996 and
for subsequent fiscal years and certain business plan information for such

there are uncertainties inherent in attempting to make such estimates,
projections and other forecasts and plans, that Buyer and Parents are familiar
with such uncertainties, that Buyer or Parents are taking full responsibility
for making their own evaluation of the adequacy and accuracy of all estimates,
projections and other forecasts and plans so furnished to it (including the
reasonableness of the assumptions underlying such estimates, projections and
forecasts), and that Buyer and Parents shall have no claim against the Sellers
or any other person acting on behalf of the Sellers with respect thereto.

          (a)  Buyer and Parents will use their reasonable best efforts to
     consummate the Financing.  If any portion of the Financing becomes
     unavailable, regardless of fault, then Buyer and Parents will use
     their reasonable best efforts to obtain from other sources the
     financing necessary for the consummation of the transactions
     contemplated hereby.  Consistent with the foregoing, neither Buyer nor
     Parents will take any action or omit to take any action that may
     impair their ability, or the lenders' willingness, to consummate the
     Financing.  Buyer will keep the Company reasonably informed as to the
     status of the Financing and will notify the Company promptly of any

     SECTION 5.1(d), in the event that the Trigger Event (as hereinafter
     defined) has occurred, then Buyer and Parents shall pay to the Company
     a fee of $15,000,000.  Such fee shall be payable in immediately
     available funds within two days following the occurrence of the
     Trigger Event.  As used herein, the "TRIGGER EVENT" shall mean that
     (i) Buyer has relied on the failure of the condition to the Closing
     set forth in SECTION 5.1(d) to be satisfied or waived as a basis for
     not consummating the Closing and (ii) this Agreement has been
     terminated pursuant to SECTION 7.1 for any reason other than a willful
     and material breach of this Agreement by the Sellers.

          4.9. EXPIRATION OF COVENANTS TO BE PERFORMED BEFORE CLOSING.  None of

in SECTION 4.2 may be made solely on the basis of the representations and
warranties of the Sellers as to compliance with such covenants that the Sellers
make by delivering the certificate contemplated by SECTION 5.1(a).

     an officer of Buyer and Parents confirming the foregoing to the best of
     such officer's knowledge.

          (b)  NO INJUNCTION, ETC.  No preliminary or permanent injunction
     or other order issued by any court of competent jurisdiction or
     governmental authority or other legal restraint or prohibition that
     restrains, enjoins or otherwise prohibits the transactions
     contemplated hereby shall be in effect.

     6.   EMPLOYEE RELATIONS AND BENEFITS.

          6.1. UNION REPRESENTED EMPLOYEES.

          (a)  ASSUMPTION OF COLLECTIVE BARGAINING AGREEMENTS.  At the
     Closing, the Sellers shall assign to Buyer and, except as otherwise
     provided herein, Buyer shall offer to assume the Collective Bargaining
     Agreements set forth on SCHEDULE 3.1(g)(ii) that cover Division
     Employees who are or were represented by a collective bargaining agent
     (the "UNION REPRESENTED EMPLOYEES").  Buyer shall inform each union
     representing Division Employees that it is willing to assume their
     respective Collective Bargaining Agreement. 

          (b)  EMPLOYMENT OF UNION REPRESENTED EMPLOYEES.  All of the Union
     Represented Employees who are in active employment status on the day
     immediately prior to the Closing Date ("ACTIVE UNION REPRESENTED
     EMPLOYEES") shall cease their employment status with the Sellers at
     the Effective Time and simultaneously therewith shall be offered
     employment by Buyer under the terms and conditions of the respective
     Collective Bargaining Agreements and under terms that recognize prior
     employment with the Sellers (or their predecessors) for purposes of
     all Benefit Plans, Benefit Arrangements or other seniority based
     programs or benefits.  For purposes of this SECTION 6.1, the term
     "ACTIVE EMPLOYMENT STATUS" includes any individual not actively at
     work due to illness, short-term disability or sick leave, authorized
     leave of absence, layoff for lack of work or service in the Armed
     Forces of the United States, but does not include any individual not
     actively at work due to retirement, resignation, permanent dismissal
     or long-term disability.  In addition, any Union Represented Employee
     who is not an Active Union Represented Employee in accordance with the
     foregoing 


                                      -37-

<PAGE>

provisions of this SECTION 6.1(b) ("NON-ACTIVE UNION REPRESENTED EMPLOYEES") but
who has a right to return to employment with Buyer under the Collective
Bargaining Agreement applicable to such employee or pursuant to any applicable
law shall be extended an employment offer by Buyer at the time each such
employee is eligible to return to work, if at all, under the Collective
Bargaining Agreement applicable to such employee or pursuant to any applicable
law, and if employed, shall become an Active Union Represented Employee at that
time.

          (c)  DEFINED BENEFIT PENSION PLANS.

               (i)  The Sellers shall retain all of the assets of the A.O.
          Smith Retirement Plan ("RETIREMENT PLAN") and the liabilities for
          (A) all benefits payable under the Retirement Plan with respect
          to Non-Active Union Represented Employees who retired or
          otherwise terminated employment on or prior to the Closing Date,
          (B) the "basic retirement benefit" accrued by Active Union
          Represented Employees through the Closing Date, and (C) to the
          extent provided under SECTION 6.1(c)(iii), (iv) and (v), the
          subsidized value of early retirement benefits, early retirement
          supplements, retiree benefit increases and pension enhancements
          related to Medicare eligibility for Active Union Represented
          Employees.  For purposes of this SECTION 6.1, the term "basic
          retirement benefit" means the monthly normal retirement age
          benefit accrued under the Retirement Plan on the Closing Date
          based upon the employee's credited service under the Retirement
          Plan through the Closing Date, exclusive of the subsidized value
          of any early retirement benefit, early retirement supplements,
          pension enhancements related to Medicare eligibility, retiree
          benefit increases, or any other benefit, supplement or subsidy
          under the Retirement Plan that the employee would have earned in
          addition thereto had he continued employment with the Sellers.

               (ii) As of the Effective Time, Buyer shall establish for
          Active Union Represented Employees a pension plan or plans
          intended to qualify under Section 401(a) of the Code and that are
          identical to the Retirement Plan as in effect for Union
          Represented Employees ("BUYER PENSION PLAN").  For purposes of
          eligibility, vesting and benefit accrual, Buyer Pension Plan
          shall credit each Active Union Represented Employee with service
          for periods prior to the Effective Time equal to the service
          credited to such employee under the Retirement Plan; provided,
          however, that Buyer Pension Plan may offset benefits provided
          under the Retirement Plan in order to avoid duplication of
          benefits on account of periods of service recognized under both
          the Retirement Plan and Buyer Pension Plan.  To the extent not
          provided by the Retirement Plan in accordance with SECTION
          6.1(c)(iii), (iv) and (v), Buyer Pension Plan shall be
          responsible for the subsidized value of early retirement
          benefits, early retirement supplements, pension enhancements
          related to Medicare eligibility and retiree benefit increases
          provided to Active Union Represented Employees.  Further, Buyer
          Pension Plan shall be solely responsible for providing disability
          benefits for Active Union Represented Employees who become
          disabled on or after the Closing Date other than for any
          participant who is in the disability waiting period as of the
          Effective Time, for whom the Retirement Plan shall be solely
          responsible.

               (iii)     As of the Effective Time, the Sellers shall amend
          the Retirement Plan in the following respects:

                    (A)  An Active Union Represented Employee shall be
          entitled to commence his benefit under the Retirement Plan only
          if the employee, in addition to satisfying the otherwise
          applicable requirements for commencement of his benefit, has
          retired or terminated from employment with Buyer;

                    (B)  For purposes of determining the employee's
          eligibility for early retirement benefits, early retirement
          supplements, retiree benefit increases and pension enhancements
          related to Medicare eligibility, but not for purposes of
          determining an employee's credited service under the Retirement
          Plan or for any other purpose, the Retirement Plan shall
          recognize an Active Union Represented Employee's employment with
          the Buyer as if such employment were rendered to the Sellers.

                    (C)  In the case of an Active Union Represented
          Employee who is a participant in the Retirement Plan, who retires
          on or after the Closing Date with an entitlement to a normal or
          early retirement benefit under the terms of Buyer Pension Plan,
          and who either is eligible for a normal or early retirement
          benefit from the Retirement Plan or would have been eligible for
          a normal or early retirement benefit under the Retirement Plan
          had his employment with Buyer instead been rendered to the
          Sellers, then:

                         (I)  The employee shall be eligible for retiree
               benefit increases in accordance with the terms of the
               Retirement Plan as in effect on the Closing Date based on
               the employee's credited service through the Closing Date. 
               Buyer Pension Plan shall be responsible for all remaining
               retiree benefit increases.

                         (II) The employee shall be eligible for a pension
               enhancement related to Medicare eligibility in accordance
               with the terms of the Retirement Plan as in effect on the
               Closing Date that 


                                      -39-

<PAGE>

               is prorated between the Retirement Plan and Buyer Pension Plan in
               accordance with SECTION 6.1(c)(iv).

                         (III)     If the employee elects early retirement
               benefits, the Retirement Plan shall be responsible for the
               subsidized value of early retirement benefits payable from
               the Retirement Plan, and Buyer Pension Plan shall be
               responsible for the subsidized value of early retirement
               benefits payable from Buyer Pension Plan, and the early
               retirement supplement (if any) shall be prorated between the
               Retirement Plan and Buyer Pension Plan in accordance with
               SECTION 6.1(c)(v).

               (iv) The pension enhancement related to Medicare eligibility
          to be provided under the Retirement Plan shall be equal to the
          lesser of (A) the pension enhancement calculated under the terms
          of the Retirement Plan as in effect on the day prior to the
          Closing Date multiplied by a fraction, the numerator of which is
          the employee's years of credited service under the Retirement
          Plan through the Closing Date, and the denominator of which is
          the sum of the numerator and the employee's service with Buyer
          from the Closing Date through the employee's retirement or
          termination of employment from Buyer, or (B) the pension
          enhancement calculated under the terms of Buyer's Pension Plan as
          in effect on the employee's retirement or termination of
          employment from Buyer (prior to reduction for the portion of the
          enhancement to be paid from the Retirement Plan) multiplied by a
          fraction, the numerator of which is the employee's years of
          credited service under the Retirement Plan through the Closing
          Date, and the denominator of which is the sum of the numerator
          and the employee's service with Buyer from the Closing Date
          through the employee's retirement or termination of employment
          from Buyer.  Buyer Pension Plan shall be responsible for any
          remaining pension enhancement related to Medicare eligibility.  

               (v)  The early retirement supplement to be provided under
          the Retirement Plan shall be equal to the lesser of (A) the early
          retirement supplement calculated under the terms of the
          Retirement Plan as in effect on the day prior to the Closing Date
          multiplied by a fraction, the numerator of which is the
          employee's years of credited service under the Retirement Plan
          through the Closing Date, and the denominator of which is the sum
          of the numerator and the employee's service with Buyer from the
          Closing Date through the employee's retirement or termination of
          employment from Buyer, or (B) the early retirement supplement
          calculated under the terms of Buyer's Pension Plan as in effect
          on the employee's retirement or termination of employment from
          Buyer (prior to reduction for the portion of the supplement to be
          paid from the Retirement Plan) multiplied by a 


                                      -40-

<PAGE>

          fraction, the numerator of which is the employee's years of credited
          service under the Retirement Plan through the Closing Date, and the
          denominator of which is the sum of the numerator and the employee's
          service with Buyer from the Closing Date through the employee's
          retirement or termination of employment from Buyer.  Buyer Pension
          Plan shall be responsible for any remaining early retirement
          supplement. Notwithstanding the foregoing, an early retirement
          supplement shall not be paid from the Retirement Plan, and Buyer's
          Pension Plan shall be solely responsible for any early retirement
          supplement payable with respect to an Active Union Represented
          Employee retiring on or after the Closing Date if such employee's
          involuntary retirement or termination of employment is the result of
          any event which requires notice to be given to such employee pursuant
          to WARN, including any reduction in force, mass layoff or plant
          closing; provided, that this exclusion shall not apply to any employee
          whose retirement or termination of employment occurs in the ordinary
          course of business, is connected with the transfer of the heavy truck
          business to the Roanoke facility, or where the employee has been
          offered a comparable position within the organization and has declined
          the offer.

               (vi) Buyer and the Sellers agree that the provisions of this
          Section 6.1(c) are intended to be consistent with applicable law,
          including, without limitation, the requirements of Section 414(l)
          of the Code.  Accordingly, nothing in this Section 6.1(c) is
          intended to result in a transfer from the Retirement Plan to
          Buyer Pension Plan within the meaning of Section 414(l) of the
          Code.

          (d)  DEFINED CONTRIBUTION RETIREMENT PLANS.  At Closing, Buyer
     shall assume sponsorship of the A. O. Smith Employee 401(k) Savings
     Plan, A. O. Smith Employee Savings Plan and A. O. Smith Savings
     Investment Plan.  In addition, Buyer shall establish or designate a
     defined contribution retirement plan that is substantially comparable
     to the portion of the A. O. Smith Corporation Savings and Security
     Plan covering Union Represented Employees ("BUYER SAVINGS PLAN").  On
     or before the last day of the remedial amendment period described in
     Section 401(b) of the Code and the regulations thereunder, Buyer shall
     file with the Internal Revenue Service an appropriate application for
     a determination letter holding that Buyer Savings Plan satisfies the
     applicable requirements for qualification and exemption under Sections
     401(a) and 501(a) of the Code, and shall, no later than the last day
     of such remedial amendment period, take such corrective action as may
     be necessary in order to secure such determination letter.  Upon
     evidence satisfactory to the Sellers relative to the establishment of
     Buyer Savings Plan and the filing of a determination letter
     application, the Sellers shall cause the trustee of the A. O. Smith
     Corporation Savings and Security Plan to transfer the account balances
     of Active Union Represented Employees to Buyer Savings Plan.

     accidental death and dismemberment benefits on behalf of Union
     Represented Employees that are incurred prior to the Effective Time
     (including, without limitation, benefits for claims incurred prior to
     the Effective Time but for which the claim is received on or after the

     behalf of Union Represented Employees (including Union Represented
     Employees who retired or terminated employment prior to the Effective
     Time) that are incurred at or after the Effective Time.  The Sellers
     shall use their reasonable best efforts (i) to assign or otherwise
     transfer to Buyer any group policy or Contract governing welfare
     benefits (including, but not limited to, those relating to health,
     dental, prescription drug, life, accidental death and dismemberment,

     maintained on a stand-alone basis, and (ii) in the case of a group
     policy or Contract governing welfare benefits (including, but not
     limited to, those relating to health, dental, prescription drug, life,

     Union Represented Employees but maintained under a Contract or policy
     covering both Union Represented and Employees and other employees of
     the Sellers, to assign or otherwise transfer to Buyer the portion of
     the policy or Contract covering Union Represented Employees.

     6.2. HOURLY PAID NON-UNION REPRESENTED EMPLOYEES AND SALARIED EMPLOYEES.
    
          (a)  EMPLOYMENT.  All of the hourly paid Division Employees not
     represented by a collective bargaining agent and all of the Division
     Employees who are paid on a salaried or commission basis
     (collectively, "NON-REPRESENTED EMPLOYEES") who are in active
     employment status on the day immediately prior to the Closing Date
     ("ACTIVE NON-REPRESENTED EMPLOYEES") shall cease their employment
     status with the Sellers at the Effective Time and simultaneously
     therewith shall be offered employment by Buyer under terms that,
     except as provided in SECTION 6.2(c), recognize prior employment with
     the Sellers (or their predecessors) for purposes of all Benefit Plans,
     Benefit Arrangements or other seniority based programs or benefits. 
     For purposes of this SECTION 6.2, the term "ACTIVE EMPLOYMENT STATUS"
     includes any individual not actively at work due to illness, short-
     term disability or sick leave, authorized leave of absence, layoff for
     lack of work, or service in the Armed Forces of the United States but
     does not include any individual not actively at work due to
     retirement, resignation, permanent dismissal or long-term disability. 
     In addition, any Non-Represented Employee who is not an Active Non-
     Represented Employee in accordance with the foregoing provisions of
     this SECTION 6.2 ("NON-REPRESENTED NON-ACTIVE EMPLOYEES") but who has
     a right to return to employment under the applicable policies of the
     Sellers or pursuant to any applicable law shall be extended an 


                                      -42-

<PAGE>

     employment offer by Buyer at the time each such employee is eligible to
     return to work or additional employment in the applicable job
     classification is deemed warranted by Buyer.  If such Non-Represented Non-
     Active Employee is employed by Buyer pursuant to the preceding sentence,
     then such employee shall become an Active Non-Represented Employee as of
     the date the person returns to employment.

          (b)  WAGE RATES.  Buyer shall make each Active Non-Represented
     Employee an offer an employment at the same current base rate of pay
     or salary, as applicable, that was in effect for such employee
     immediately prior to the Closing Date, provided that Buyer may adjust
     any individual Non-Represented Employee's wage rate at any time after
     employment is accepted.

          (c)  DEFINED BENEFIT PENSION PLANS.  The Sellers shall retain all
     of the assets of the Retirement Plan and the A. O. Smith Enterprises
     Ltd. Stratford Plant Industrial Pension Plan ("CANADIAN PLAN") and the
     liabilities for benefits accrued through the Closing Date under such
     plans.  Effective as of the Effective Time, Buyer shall establish for
     Active Non-Represented Employees a defined benefit pension plan or
     plans that is or are substantially comparable to the Retirement Plan
     as in effect for Non-Represented Employees.  Buyer's plan shall
     recognize employment with the Sellers for purposes of eligibility and
     vesting under Buyer's plan, but need not recognize employment with the
     Sellers for purposes of benefit accrual.  Effective as of the
     Effective Time, Seller shall amend the Retirement Plan and the
     Canadian Plan to provide (1) an Active Non-Represented Employee shall
     be entitled to commence his benefit under the Retirement Plan or
     Canadian Plan only if the employee, in addition to satisfying the
     otherwise applicable requirements for commencement of his benefit, has
     retired or terminated from employment with Buyer, and (2) an Active
     Non-Represented Employee's service with Buyer shall be considered for
     purposes of determining the employee's eligibility for early
     retirement benefits under each plan (but not for purposes of accruing
     additional benefits thereunder).

          (d)  DEFINED CONTRIBUTION RETIREMENT PLANS.  (i) Effective as of
     the Effective Time, Buyer shall establish for Active Non-Represented
     Employees (or otherwise include Active Non-Represented Employees in) a
     defined contribution plan or plans that either continue a level of
     benefits provided by the Sellers or that provide benefits comparable
     to those provided by Buyer to its non-represented employees ("BUYER
     DEFINED CONTRIBUTION PLAN"); provided that in the case of an Active
     Non-Represented Employee who either participated in or was eligible to
     participate in the A.O. Smith Profit Sharing Retirement Plan, the
     minimum level of employer matching contributions under Buyer Defined
     Contribution Plan for the period beginning  on January 1, 1997 and
     ending on December 31, 1997 shall be 35 cents for each dollar of pre-
     tax contributions (including pre-tax contributions made between
     January 1, 1997 and the Effective Time under the A.O. Smith Profit 


                                      -43-

<PAGE>

     Sharing Retirement Plan) up to six percent of the employee's compensation
     for the year (including compensation paid between January 1, 1997 and the
     Effective Time by Sellers).  Buyer's plan shall recognize employment with
     the Sellers for purposes of eligibility and vesting under Buyer's plan.

          (ii) On or before the last day of the remedial amendment period
     described in Section 401(a) of the Code and the regulations
     thereunder, Buyer shall file with the Internal Revenue Service an
     appropriate application for a determination letter holding that Buyer
     Defined Contribution Plan satisfies the applicable requirements for
     qualification and exemption under Section 401(a) and 501(a) of the
     Code, and shall, no later than the last day of such remedial amendment
     period, take such corrective action as may be necessary in order to
     secure such determination letter.  Upon evidence satisfactory to the
     Sellers relative to the establishment of Buyer Defined Contribution
     Plan and the filing of a determination letter application, the Sellers
     shall cause the trustee of the applicable A.O. Smith defined
     contribution plan to transfer the account balances of Active Non-
     Represented Employees to Buyer's Defined Contribution Plan; provided,
     that participant loans shall be transferred in-kind.

          (e)  WELFARE BENEFIT PLANS AND ARRANGEMENTS. The Sellers (or the
     Sellers' third party administrator or insurer) shall process and pay
     all eligible claims for health, dental, prescription drug, life, and
     accidental death and dismemberment benefits on behalf of Non-
     Represented Employees that are incurred prior to the Effective Time
     (including, without limitation, benefits for claims incurred prior to
     the Effective Time but for which the claim is received on or after the
     Effective Time).  Buyer (or Buyer's third party administrator or
     insurer) shall process and pay all eligible claims for benefits on
     behalf of Non-Represented Employees (including Non-Represented
     Employees who retired or terminated employment prior to the Effective
     Time) that are incurred on or after the Effective Time.  The Sellers
     shall use their reasonable best efforts (i) to assign or otherwise
     transfer to Buyer any group policy or Contract governing welfare
     benefits (including, but not limited to, those relating to health,
     dental, prescription drug, life, accidental death and dismemberment,
     and sickness and accident) for Non-Represented Employees that is
     maintained on a stand-alone basis, and (ii) in the case of a group
     policy or Contract governing welfare benefits (including, but not
     limited to, those relating to health, dental, prescription drug, life,
     accidental death and dismemberment, and sickness and accident) for
     Non-Represented Employees but maintained under a Contract or policy
     covering both Non-Represented and Employees and other employees of the
     Sellers, to assign or otherwise transfer to Buyer the portion of the
     policy or Contract covering Non-Represented Employees.

          (f)  SEVERANCE BENEFITS.  Effective as of the Effective Time,
     Buyer shall establish and maintain for a period of at least twelve
     (12) months a severance pay plan that recognizes prior employment with
     the Sellers (or their predecessors) and 


                                      -44-

<PAGE>

     that provides severance benefits under the same conditions and at least as
     generous in amount as those provided under the A. O. Smith Severance Pay
     Plan identified on SCHEDULE 3.1(N).  In addition, Buyer agrees to indemnify
     the Sellers for all severance benefits payable by the Sellers under the
     A. O. Smith Severance Pay Plan and costs incurred in connection with such
     benefits (including, without limitation, attorneys' fees incurred in
     defending against a claim for severance benefits) to the extent that any
     such claim for severance benefits is based, in whole or in part, on Buyer's
     failure or refusal to offer employment to Division Employees in accordance
     with the terms of this SECTION 6 or the termination of any Division
     Employee within twelve (12) months after the Closing.

          (g)  BONUS PAYMENTS.  Buyer shall continue Seller's bonus plans
     that are in effect as of the Effective Time for the duration of the
     1997 calendar year and shall pay bonuses in accordance therewith. 
     Buyer and Seller shall cooperate in the determination of the bonuses
     that are payable thereunder for 1997.  Seller shall promptly reimburse
     Buyer for the portion of the 1997 bonuses paid by Buyer which is
     attributable to the pre-closing period, such proportion shall be
     determined by dividing the number of calendar days preceding the
     Effective Time by 365.

          (h)  SECTION 125 PLAN. Buyer shall assume, and Seller shall
     transfer, the portion of the A.O. Smith Flexible Benefits Plan which
     is attributable to the 1997 plan year participation of Business
     employees.

          (i)  EXECUTIVE RETIREMENT BENEFITS. Seller shall remain liable
     for obligations accrued under the A.O. Smith Corporation Executive
     Life Insurance Plan and the A.O. Smith Supplemental Benefit Plan with
     respect to any employee of the Business and Buyer shall not assume any
     liability or obligation with respect thereto.

          (j)  WORKERS' COMPENSATION OBLIGATIONS.  Seller shall remain
     liable for all workers' compensation obligations which relate to
     injuries incurred prior to the Effective Time; provided that in the
     case of an injury for which the date of incurrence cannot be
     ascertained (including, without limitation, occupational disease or
     repetitive motion claims), Seller shall be liable only for claims
     filed prior to the Effective Time and Buyer shall be liable for all
     claims filed on or after the Effective Time. 

          6.3. REQUIRED NOTICE.  Buyer will provide any plant closing notices as
required under federal, provincial, state or local law (including without
limitation, the Warn Act) as a result of the transactions contemplated in this
Agreement, and Buyer and Parents shall indemnify, defend and hold the Sellers
harmless from and against any and all liability incurred by the Sellers, or
either one of them, as a result of Buyer's failure to provide such notice on a
timely and effective basis.

          6.4. VACATION.  With respect to any accrued but unused vacation time
to which any Active Non-Represented Employee is entitled pursuant to the
vacation policy applicable to such employee immediately prior to the Closing
Date (the "VACATION POLICY"), Buyer shall allow such employee to use such
accrued vacation; provided, however, that if Buyer deems it necessary to
disallow such employee from taking such accrued vacation, then Buyer shall be
liable for and pay in cash to each such employee an amount equal to such
vacation time in accordance with terms of the Vacation Policy.

          6.5. PAYROLL TAX.  The Company and Buyer agree that, with respect to
Division Employees who are employed by Buyer following to Closing pursuant to
this ARTICLE 6 ("CONTINUING EMPLOYEES"), they respectively meet the definitions
of "predecessor" and "successor" as defined in Revenue Procedure 96-60.  For
purposes of reporting employee remuneration to the IRS on Forms W-2 and W-3 for
the calendar year within which the Closing Date occurs, the Company and Buyer
will utilize the "Standard Procedure" described in Section 4 of Revenue
Procedure 96-60.  The Company and Buyer agree that, for purposes of reporting
employee remuneration for Federal Insurance Contributions Act ("FICA") purposes
for the calendar year within which the Closing Date occurs, the Company meets
the definition of "predecessor" and Buyer meets the definition of "successor" as
defined in IRS Regulation Section 31.3121(a)(1)-1(b).  The Company will supply
to Buyer, with respect to all Continuing Employees, all cumulative payroll
information as of the Closing Date that Buyer shall require in order to employ
IRS Regulation Section 31.3121(a)(1)-1(b).

     7.   TERMINATION.

          7.1. GENERAL.  This Agreement may be terminated and the transactions

     supplemented by this Agreement and the Access Agreement) which shall
     remain in full force and effect, as modified or supplemented by this
     Agreement and the Access Agreement, notwithstanding the termination of
     this Agreement; and

          (c)  to the extent required thereunder, Buyer and Parents shall
     pay all fees to the Company required under SECTION 4.8(b).

          7.3. NO LIABILITIES IN EVENT OF TERMINATION.  In the event of any
termination of this Agreement as provided in SECTION 7.1, this Agreement shall
forthwith become wholly void and of no further force and effect and there shall
be no liability on the part of Buyer or the Sellers, except that the respective
obligations of Buyer, Parents and/or the Sellers, as the case may be, under
SECTIONS 4.1, 4.8(b), 9.1, 9.2 and SECTION 7.2 of this Agreement shall remain in
full force and effect, and except that termination shall not preclude any party
from suing the other party for breach of this Agreement or impair the right of
any party to compel specific performance by another party of its obligations
under SECTIONS 4.1, 4.8(b), 9.1, 9.2 and SECTION 7.2 of this Agreement.

     8.   TRANSACTIONS SUBSEQUENT TO CLOSING.

          8.1. POST-CLOSING ACCESS TO INFORMATION AND ASSISTANCE.

          (a)  For a period of seven (7) years after the Closing Date, each
     party hereto shall provide, and shall cause its appropriate personnel
     to provide, when reasonably requested to do so by another party,
     access to all tax, financial and accounting records and any other
     records transferred to Buyer or retained by the Sellers, as
     applicable, in accordance with this Agreement (other than in
     connection with a dispute between the parties relating to the
     transactions contemplated by this Agreement) and the right to make
     copies or extracts therefrom at its expense.  Neither party shall, nor
     shall it permit its affiliates to, intentionally dispose of, alter or
     destroy any such books, records and other data without giving thirty
     (30) days' prior written notice to the other party and permitting the
     other parties hereto, 


                                      -47-

<PAGE>

at their expense, to examine, duplicate or repossess such records, files,
documents and correspondence.

          (b)  Each party agrees to cooperate with the other party in the
     preparation for and prosecution of the defense of any claim, action or
     cause of action arising out of or relating to any Liability relating
     to the Business which arose prior to the Closing and which, in the
     case of Buyer and Parents, has been assumed by Buyer and Parents, or,
     in the case of the Sellers, has been retained by the Sellers,
     including, without limitation, by making available evidence within the
     cooperating party's control and persons needed as witnesses employed
     by the cooperating party, as reasonably needed for such defense. 
     Except as provided in SECTION 9.3, the requesting party shall
     reimburse the cooperating party for its actual out-of-pocket costs
     relating to its cooperation under this SECTION 8.1(B) and for a pro
     rata portion of the salary (including fringe benefits, with such pro
     rata portion determined based upon the time spent in connection with
     such cooperation) and for travel and subsistence expenses directly
     relating to the cooperation of any of the cooperating party's
     employees who assist the requesting party.

          8.2. FURTHER AGREEMENTS.  The Sellers authorize and empower Buyer on
and after the Closing Date to receive and open all mail received by Buyer
relating to the Business or the Assets and to deal with the contents of such
communications in any proper manner.  The Sellers shall promptly deliver to
Buyer any mail or other communication received by them after the Closing Date
pertaining to the Business or the Assets and any cash, checks or other
instruments of payment to which Buyer is entitled.  Buyer shall promptly deliver
to the Sellers any mail or other communication received by it after the Closing
Date pertaining to the assets and liabilities described in SECTIONS 1.2 AND 1.5,
and any cash, checks or other instruments of payment in respect thereof.

          8.3. NO COMPETITION.

          (a)  During the period commencing on the Closing Date and ending
     on the fifth anniversary of the Closing Date, the Sellers will not,
     and will cause any person that is a subsidiary of either or both of
     them not to, directly or indirectly, conduct or engage in the design,
     engineering, manufacturing and marketing of structural and suspension
     components, structural and suspension assemblies and structural and
     suspension modules for light vehicles, medium trucks and heavy trucks
     (the "RESTRICTED BUSINESS").  Notwithstanding the foregoing, neither
     the Sellers nor any of their existing or future subsidiaries shall be
     in violation of this SECTION 8.3 if either or both of them continue to
     operate the assets excluded from sale hereunder pursuant to
     SECTION 1.2 in substantially the same manner as their current
     operations.

          (b)  For a period of one year from the Closing Date, the Sellers
     will not, without the prior written consent of Buyer, directly or
     indirectly contact or solicit 



                                      -48-

<PAGE>

     for the purpose of offering employment to or hiring (whether as an
     employee, consultant, agent, independent contractor or otherwise) any
     management or other key employee employed by the Sellers in the Business at
     any time during the 180 days prior to the Closing Date other than those
     identified on SCHEDULE 8.3, but the foregoing shall not prohibit
     solicitations to the public in general.

          8.4. ASSISTANCE AND COOPERATION REGARDING TAXES AND FINANCIAL
STATEMENTS.  After the Closing Date, Buyer shall cooperate and shall cause its
appropriate personnel to cooperate in providing the Sellers with such
information and assistance with respect to financial and tax matters as the
Sellers shall reasonably request to enable (i) the Sellers to prepare their
returns and pay Taxes, including all Taxes related to the Sellers' operation of
the Division prior to the Closing Date for which Buyer is not otherwise
responsible pursuant to this Agreement and (ii) the Company to prepare its
consolidated financial statements.  The Company shall reimburse Buyer for its
actual out-of-pocket costs relating to its cooperation under this SECTION 8.4
and for a pro rata portion of the salary (including fringe benefits, with such
pro rata portion determined based upon the time spent in connection with such
cooperation) and for travel and subsistence expenses directly relating to the
cooperation of any of Buyer's employees who assist the Sellers under this
SECTION 8.4.

          8.5. CORPORATE NAMES.

          (a)  USE OF NAMES.  Effective from and after the Closing and up
     to the date six (6) months from the Closing Date, the Company hereby
     grants Buyer the nonexclusive, royalty-free right to use (without
     right of sublicense) the name "A. O. Smith" or any derivation thereof
     and any corporate symbols or logos related thereto, but only in
     connection with the conduct and operation of the Business relating to:

               (i)  INVENTORIES.  The use of existing Inventories which
          bear the name "A. O. Smith" or derivations thereof; and

               (ii) SUPPLIES.  The use of existing stationery, packaging,
          shipping, invoices, purchase orders and marketing materials
          ("SUPPLIES") which bear the name "A. O. Smith" or derivations
          thereof; PROVIDED, HOWEVER, that Buyer shall overprint,
          overstamp, apply on an appropriate label or otherwise obliterate
          such names and logos on such items or otherwise indicate that
          Buyer, and not the Sellers, is the party contracting or otherwise
          performing in connection with such Supplies;

     PROVIDED, HOWEVER, that neither Buyer, China JV (following the
     Closing) nor Brazil Sub (following the Closing) shall represent or
     hold itself out as representing the Sellers or any one of them and
     PROVIDED FURTHER, HOWEVER, that Buyer and Parents shall indemnify and
     hold harmless the Sellers from any loss, damage, cost or expense
     (including reasonable attorneys' fees) incurred by the Sellers as a
     result 


                                      -49-

<PAGE>

     of Buyer's, China JV's (following the Closing) or Brazil Sub's (following
     the Closing) use of such names or symbols or logos.  The rights provided
     for in SECTION 8.5(a)(i) are subject to the Company's right to require the
     Buyer to take such reasonable action as the Company deems necessary to
     maintain appropriate quality control of the Inventories.

          (b)  CHANGE OF NAME.  Buyer acknowledges that, except for the
     limited right granted by this Section, it has no right or interest in
     the name "A. O. Smith" or "Smith".  Prior to the date sixty (60) days
     from the Closing Date, Buyer shall take all such action as is
     necessary to cause China JV and Brazil Sub to take any and all such
     action and to make all filings as necessary to change their corporate
     names to names that do not contain "A. O. Smith" or "Smith" or any
     substantially or confusingly similar name or reference and, except as
     provided in SECTION 8.5(a), to thereafter cease from using any name,
     trade name, trademark or service mark or any related logos
     incorporating "A. O. Smith" or "Smith" in any manner whatsoever.

          8.6. COMPANY'S INSURERS OR ADMINISTRATORS.

          (a)  Buyer acknowledges that the Company or an affiliate thereof
     may be making payments after the Closing to the Company's insurers or
     claims processors or administrators ("COMPANY'S INSURERS") in respect
     of (i) the self-insured retention portion of any workers compensation,
     product liability, general liability and automobile liability claims
     relating to the Company or any of its affiliates made or to be made in
     the future in respect of periods prior to the Closing, and (ii)
     medical and other claims and related administrative costs relating to
     the Company or any of its affiliates made or to be made in the future
     in respect of periods prior to the Closing, in each case including
     associated claims handling charges, for which the Company or any of
     its affiliates is responsible with respect to Company's Insurers and
     for which Buyer and Parents have assumed the Liability  pursuant to
     SECTION 1.4 (collectively, "CLAIMS").  Without in any way limiting the
     generality of SECTION 1.4, Buyer and Parents will pay each Claim or
     reimburse the Company therefor within five (5) days after the Company
     advises Buyer of the amount thereof and provides Buyer with an invoice
     from Company's Insurers or other documentation reasonably satisfactory
     to Buyer to the Claim (the "ADVICE DATE").  If Buyer or Parents fail
     to pay any Claim or reimburse the Company therefor within five (5)
     days of the Advice Date, then Buyer and Parents shall pay to the
     Company interest on the amount thereof at an annual rate equal to the
     Applicable Rate from and including the Advice Date to but not
     including the date of payment.

          (b)  The Sellers shall take all legally proper and appropriate
     actions (i) to maintain the effectiveness and enforceability of each
     Insurance Policy with respect to insurance coverage for events
     occurring, or facts existing, on or prior 


                                      -50-

<PAGE>

     to the Closing Date, including without limitation satisfying all conditions
     precedent and all other obligations under such Insurance Policies in each
     case that are within the control of the Sellers, and (ii) following the
     Closing at the written request of Buyer, to obtain the proceeds of such
     insurance coverage under each Insurance Policy, provided that Buyer has
     delivered its request on a timely basis and delivered to the Sellers all
     information reasonably requested by the Sellers; provided, however, that
     this SECTION 8.6(B) shall not obligate the Sellers to commence litigation
     unless (A) Buyer requests the Sellers to do so and agrees to bear the
     Sellers' reasonable expenses incurred in pursuing such litigation and (B)
     the Sellers conclude, in the exercise of their reasonable business
     judgement based on advice of counsel, that litigation is a viable remedy. 
     If the Sellers receive notice of a matter as to which it is reasonably
     apparent that Buyer would be reasonably likely to request the Sellers to
     obtain proceeds under an Insurance Policy with respect to the matter under
     this SECTION 8.6(B) assuming Buyer was aware of such matter, then Buyer
     will be deemed to have submitted a request to the Sellers pursuant to
     CLAUSE (II) above.

          (c)  With respect to Insurance Policies covering business
     interruptions, if an event is occurring, or is reasonably likely to
     occur, prior to the Effective Time that would entitle the Sellers to
     any insurance proceeds under such Insurance Policies, the Sellers
     shall (i) take all legally proper and appropriate actions to maintain
     the effectiveness and enforceability of such Insurance Policies until
     such event, or the likelihood of such event, has ceased and (ii) at
     the Closing in respect of any proceeds received prior to the Closing
     and immediately as to proceeds received thereafter, deliver to Buyer
     all proceeds of such coverage that relate to any period of time
     following the Closing Date.  The Sellers have complied, or will comply
     within the requisite period, with the "Reporting Requirements" of the
     applicable "Business Interruption Endorsement."

          8.7. CERTAIN POST-CLOSING SERVICES.  At the Closing, Buyer and the
Sellers shall enter into an agreement in the form of EXHIBIT 8.7 (the
"TRANSITION SERVICES AGREEMENT") pursuant to which the Sellers shall perform
certain services for Buyer and Buyer shall perform certain services for the
Sellers on the terms and conditions set forth in the Transition Services
Agreement and such other terms and conditions to which the Sellers and Buyer
agree, subject to the following:  (a) Buyer shall be obligated to provide
services relating to the defense of the matters described in items 2 and 3 of
EXHIBIT 1.5(h) until their resolution; (b) the Sellers' obligation to provide
services shall expire no later than December 31, 1997; (c) the Sellers shall be
obligated to provide services only in respect of all or a portion of the matters
identified in item 2.c. of SCHEDULE 3.1(f); and (d) the charge for providing
services shall reflect the provider's actual out-of-pocket costs relating to the
provision of such services and a pro rata portion of the salary (including
fringe benefits, with such pro rata portion determined based upon the time spent
in connection with providing services) and travel and subsistence expenses
directly relating to the provision of services by any of the provider's
employees who assist in providing services.  Subject 


                                      -51-

<PAGE>

to the foregoing, prior to the Closing, the Sellers and Buyer shall negotiate in
good faith with respect to the remaining terms of the Transition Services
Agreement.

          8.8. FURTHER ASSURANCES.  From time to time after the Closing Date,
the Sellers, on the one hand, and Buyer, on the other hand, will execute and
deliver, or cause to be executed and delivered, such other instruments of
conveyance, assignment, transfer and delivery and will take such other actions
as the other may reasonably request in order to more effectively consummate the
transactions contemplated hereby, such as to transfer, convey, assign, and
deliver to Buyer any of the Assets, or enable Buyer and Parents to discharge the
Assumed Liabilities, or enable Buyer to exercise and enjoy all rights, benefits
and obligations of the Sellers with respect thereto.

          8.9. LICENSE OF CERTAIN PATENTS.  On the Closing Date, Buyer and the
Sellers shall enter into a License Agreement in the form attached hereto as
EXHIBIT 8.9 .

          8.10.     FINANCIAL STATEMENT AUDITS.  If Buyer or Parents, or any one
of them, desires to have completed audited or interim financial statements for
the Business for any period commencing on or after January 1, 1994, then, at
Buyer's election, the Sellers shall request the Company's external auditors to
complete such statements at Buyer's expense and use reasonable best efforts to
cause such auditors to do so or allow Buyer's external auditors to complete such
statements at Buyer's expense.

          8.11.     LEASES.

               (a)  The Sellers, Parents and Buyers shall have a continuing
obligation to use all reasonable best efforts to take, or cause to be taken, all
action and to do, or cause to be done, and to cooperate fully with the other
party with respect to, all things necessary, proper or advisable (i) to cause
the lessors under the Equipment Leases to bifurcate such leases into leases
relating to equipment, machinery, vehicles or other tangible personal property
utilized primarily in the Business ("BUSINESS LEASES") and leases relating to
equipment, machinery, vehicles or other tangible personal property not relating
primarily to the Business ("OTHER LEASES"), (ii) to cause the Sellers to be
released from all Liabilities under the Business Leases, any Equipment Leases
where the lessor does not agree to such bifurcation and real estate leases with
respect to Leased Real Property identified on SCHEDULE 1.1(c) and (iii) to cause
Buyer to have no Liability under the Other Leases.

               (b)  Buyer or Parents shall not agree to any modifications or
amendments to any of the Equipment Leases or any of the real estate leases
identified on SCHEDULE 3.1(g) as to which the Sellers remain a party that
increase the Sellers' Liabilities or potential Liabilities thereunder,
including, without limitation, renewing any Equipment Lease as to any leased
asset, extending the term of an Equipment Lease in whole or as to any leased
asset, adding assets to any Equipment Lease, extending the term of any real
estate lease or exercising any option thereunder, without the prior written
consent of the Sellers.  Notwithstanding the foregoing, and subject to the
continuing obligation of Buyer and Parents under SECTION 8.11(a)(ii), Buyer
shall be entitled 


                                      -52-

<PAGE>

to exercise the two consecutive five-year renewal options set forth in Section 3
of the lease dated February, 1989 and amended June 6, 1989, by and between FCBII
Limited Partnership, Lessor, and the Company.

               (c)  So long as Buyer has any Liability under Equipment Leases in
respect of any equipment, machinery, vehicles or other tangible personal
property not relating primarily to the Business ("RETAINED EQUIPMENT"), the
Sellers shall comply with all terms of the obligations under the Equipment
Leases with respect to the Retained Equipment (including without limitation the
obligation to make all payments pursuant to the Equipment Leases), and shall use
commercially reasonable best efforts to prevent and/or cure any defaults that
may arise under the Equipment Leases as a result of the Sellers' or their
affiliates' actions or inactions.  The Sellers shall indemnify and hold harmless
Buyer and Parents with respect to any Liabilities arising in connection with the
Equipment Leases as to Retained Equipment or in connection with the Other
Leases.  Buyer and Parents shall indemnify and hold harmless the Sellers with
respect to any Liabilities arising in connection with the Equipment Leases as to
equipment, machinery, vehicles or other tangible personal property utilized
primarily in the Business, in connection with the Business Leases or in
connection with real estate leases with respect to Leased Real Property
identified on SCHEDULE 1.1(c).  Notwithstanding the foregoing, nothing set forth
herein shall prohibit Buyer from terminating any Equipment Leases after the
Closing Date provided that Buyer shall give the Sellers ninety days advance
written notice of its intent to do so.

               (d)  Notwithstanding SECTION 8.11(a), Buyer and the Sellers shall
have a continuing obligation to use all reasonable best efforts to take, or
cause to be taken, all action and to do, or cause to be done, and to cooperate
fully with the other party with respect to, all things necessary, proper or
advisable (A) to obtain an amendment of the lease, dated January 26, 1990, by
and between Harrison County Progress Corporation and the Company, and the
related Consent and Agreement dated January 23, 1990, by the Company in favor of
Prudential Insurance Company of America (together, the "CORYDON LEASE"), on
terms reasonably acceptable to Buyer and to the Sellers that shall have the
effect, without limitation, of releasing the Sellers from all obligations under
the Corydon Lease upon an assignment thereof to Buyer and deleting and/or
modifying the covenants in Article XI thereof in a manner reasonably acceptable
to Buyer and to the Sellers; (B) in the event either party shall reasonably deem
the alternative described in CLAUSE (A) unattainable, to pursue alternatives
reasonably acceptable to the Sellers and to Buyer (it being understood that,
depending upon the circumstances, the purchase of the property by Buyer and/or
prepayment of the related loan might be reasonable alternatives) that give Buyer
beneficial use of the property; and (C) in the event the Sellers and Buyer shall
fail to agree on, and consummate the actions required under, an alternative
under CLAUSE (A) or CLAUSE (B) prior to Closing, to obtain the lessor's consent
to the form of a sublease agreement for the property, complying with the terms
of Article XXIII of the Corydon Lease, requiring Buyer to comply with terms,
covenants and conditions substantially the same as those in the Corydon Lease
(including a covenant substantially the same as Section 11.3.5 thereof but
excluding the other covenants in Article XI thereof) and providing that the
Sellers shall not be liable to Buyer for any default under the Corydon Lease and
otherwise in a form reasonably acceptable to Buyer and to the Sellers, which
Buyer, Parents and the Company shall enter into at the Closing or as soon
thereafter as such 


                                      -53-

<PAGE>

consent is received; provided, however, that if the parties are not able to
obtain such consent, then (1) the beneficial interest in or to the Corydon Lease
(the "CORYDON BENEFICIAL RIGHTS") shall in any event pass as of the Closing Date
to Buyer under this Agreement and (ii) pending such consent, Buyer shall assume
or discharge the Liabilities of the Sellers under the Corydon Beneficial Rights
(to the extent such obligations are Assumed Liabilities) as agent for the
Sellers, and the Sellers shall act as Buyer's agent in the receipt of any
benefits, rights or interests received from the Corydon Beneficial Rights,
pursuant to SECTION 1.6.

the Sellers shall use commercially reasonable best efforts to cause The Welding
Institute ("TWI"), pursuant to Section 2.4 of the License Agreement between the
Company and TWI dated February 20, 1996 (the "TWI AGREEMENT"), to grant Buyer a
license.  Buyer and the Sellers shall share all fees, costs and payments
associated with obtaining such a license between Buyer and TWI in accordance
with SECTION 9.2.  In the event that TWI gives written notice, that it has made
a good faith determination that such a license between Buyer and TWI would, in
the opinion of TWI, damage its legitimate business interests, the Sellers'
obligation under this SECTION 8.12 shall be considered terminated.  In the event
the TWI Agreement is terminated or expires, the Sellers' obligation under this
SECTION 8.12 shall be considered terminated.

          8.13.     CERTAIN LITIGATION.  The Company shall defend the litigation
described in item 2 of EXHIBIT 1.5(h) (the "VEHMA LITIGATION") in good faith. 
Buyer shall nonetheless have the right to participate in the defense thereof and
to employ counsel, at its own expense, separate from the counsel employed by the
Company, it being understood, however, that the Company shall control the
defense of such litigation.  Further, Parents and Buyer shall cooperate with the
Company in the defense of such litigation in accordance with SECTION 8.1(b). 
Notwithstanding the Company's control of the defense of such litigation, (a) the
Company shall consult with Buyer regarding the defense of and the strategy with
respect to such litigation, (b) Buyer shall be free to actively monitor such
litigation, to review the files of the Company's counsel with respect thereto
(to the extent doing so will not nullify any available privileges) and to
provide input to the Company and the Company's counsel in connection therewith
and (c) the Company shall not consent to the entry of any judgment with respect
to such litigation or settle such litigation on terms that would impose any
nonmonetary relief on Buyer without the prior written consent of Buyer, which
consent shall not be unreasonably withheld or delayed.

          8.14.     CERTAIN CONTRACTS.

               (a)    Upon the written request of Buyer, the Sellers and Buyer
shall use their commercially reasonable best efforts to cause Fourth Shift
Corporation ("FOURTH SHIFT") to enter into agreements to amend the Volume
Purchase Agreement and Software License Agreement dated January 18, 1996,
between the Company and Fourth Shift (the "FOURTH SHIFT AGREEMENTS"), and to
enter into a new agreement with Buyer for the purposes of obtaining for Buyer
the rights under the Fourth Shift Agreements associated with China JV's site of
operations and preserving for the Company its other rights under the Fourth

share any fees, costs and payments associated with entering into such agreements
in accordance with SECTION 9.2.

Structures Using Intelligent and Synergistic Materials Processing, but the
Sellers shall not be obligated to forgo any benefits to which the Company is
entitled in connection with such joint venture.  The Sellers and Buyer shall
share any fees, costs and payments associated with obtaining such benefits in
accordance with SECTION 9.2.

               (c)  As to the Contracts described in paragraphs h, i, j, k, n,
p, q, r and s of Item 2 of SCHEDULE 3.1(f), upon the written request of Buyer,
the Sellers shall introduce Buyer to the other parties to such Contracts and
provide reasonable assistance to Buyer in negotiating its own arrangements with
such parties, but the Seller shall not be obligated to agree to any amendments
to Contracts between the Sellers and such other parties.  

     9.   MISCELLANEOUS.

          9.1. PUBLICITY.  The Sellers, Buyer and Parents agree that, from the
date hereof through the Closing Date, no public release or announcement
concerning the transactions contemplated hereby shall be issued or made by any
party without the prior consent of the other party (which consent shall not be
unreasonably withheld), except (i) as such release or announcement may, in the
judgment of the releasing party, be required by law or the rules or regulations
of any United States securities exchange, in which case the party required to
make the release or announcement shall allow the other party reasonable time to
comment on such release or announcement in advance of such issuance, and (ii)
that the Sellers may make such announcements to their employees. 
Notwithstanding the foregoing, Buyer and the Company shall cooperate to prepare
a joint press release to be issued at the time of the signing of this Agreement
and on the Closing Date.  The Sellers, Buyer and Parents agree to keep the terms
of this Agreement confidential, except to the extent required by applicable law
or for financial reporting purposes and except that the parties may disclose

confidential).

     any consent fees, royalties or similar payments, if any, required to be
     paid in connection with the transfer of the Assets (including any interest
     charge, penalty or addition to tax with respect thereto) without regard to
     whether such Taxes or expenses are imposed on Buyer or the Sellers, or any
     one of them, except that (i) Buyer shall pay 100% of the HSR Act filing fee
     and (ii) neither party shall be liable for consent fees, royalties or
     similar payments incurred without the party's consent, which consent shall
     not be unreasonably withheld or delayed.

          9.3. INDEMNIFICATION.

          (a)  INDEMNIFICATION BY THE COMPANY.  

               (i)  Subject to the terms and conditions of this
          SECTION 9.3, the Company shall indemnify, defend and hold
          harmless Buyer and Parents, and their directors, officers,
          employees and controlling persons, from and against all Losses
          (as defined below) asserted against, resulting to, imposed upon
          or incurred by any such person, directly or indirectly, by reason
          of or resulting from (A) any Liabilities described in
          SECTION 1.5, (B) any breach of the Surviving Representations, (C)
          subject to SECTION 4.9, any breach of any covenant or agreement
          made by the Sellers contained in this Agreement, (D) the matters
          described on EXHIBIT 9.3, (E) the matters set forth on
          SCHEDULE 3.1(O), or (F) any business interruption Losses of Buyer
          attributable to any period after the Closing arising out of any
          casualty, loss or damage to any material Assets prior to the
          Closing Date, but the Company's obligation under this CLAUSE (F)
          shall be limited to the amount of the proceeds the Sellers
          receive in respect of any such period under Insurance Policies
          covering business interruptions.  As used in this Agreement, the
          term "LOSS" or "LOSSES" shall include (1) all Liabilities; (2)
          all losses, damages (BUT EXCLUDING consequential damages, lost
          profits or punitive damages other than those awarded to a third
          party), judgments, awards, penalties and settlements; (3) all
          demands, claims, suits, actions, causes of action, proceedings
          and assessments, whether or not ultimately determined to be
          valid; and (4) all costs and expenses (including, without
          limitation, interest (including prejudgment interest in any
          litigated or arbitrated matter), court costs and fees and
          expenses of attorneys and expert witnesses) of investigating,
          defending or asserting any of the foregoing.  Notwithstanding
          such exclusion from "Losses" of consequential damages and lost
          profits, "Losses" will include the amount by which Buyer's
          profits decrease due to a permanent loss of revenues by Buyer
          (without limitation, a decrease in certain revenues in one time
          period that is offset by the recovery of those certain revenues
          in one or more other time periods shall 


                                      -56-

<PAGE>

          not constitute a permanent loss of revenue) and/or an increase in
          Buyer's expenses, in either case as a result of an interruption in
          Buyer's ability to conduct any manufacturing or production operation
          for any period of time at any Facility where the cause of the
          interruption is due to a matter as to which Buyer is entitled to
          indemnification hereunder provided that Buyer has taken reasonable
          actions to mitigate such effects to the extent required by law.  That
          Losses of Buyer for which Buyer is entitled to indemnification under
          SECTION 9.3(a)(i)(b) also constitute Assumed Liabilities shall not
          preclude Buyer's right to indemnification under SECTION 9.3(a)(i)(b).

               (ii) The Company's obligations under SECTION 9.3(a)(i) shall
          be subject to the following general limitations and other terms:

                    (A)  Buyer shall have no right to indemnification under
          SECTION 9.3(a)(i)(b) or SECTION 9.3(a)(i)(e) with respect to any
          Loss or alleged Loss if Buyer requested a reduction in the Net
          Book Value reflected on the Adjusted Closing Statement on account
          of any matter forming the basis for such Loss or alleged Loss,
          unless there was no amount reflected on the Adjusted Closing
          Balance (excluding footnotes thereto) on account of the matter
          due to the fact that reflecting an amount on the Adjusted Closing
          Statement with respect to such matter would not have been in
          accordance with GAAP, or if Buyer would have been precluded from
          requesting such a reduction in the Net Book Value due to the
          provisions of SECTION 2.3(C) even if the Company and/or Buyer had
          knowledge of the matter forming the basis for such Loss or
          alleged Loss on the Closing Date;

                    (B)  if a reserve (in the form of an accrued Liability
          or an offset to an Asset or similar item) was reflected on the
          Adjusted Closing Statement relating to any matter for which Buyer
          would otherwise be entitled to indemnification under
          SECTION 9.3(a)(i), then the calculation of Buyer's Losses in
          respect of such matter shall be reduced by the sum of the full
          amount of the reserve as reflected in the calculation of Net Book
          Value on the Adjusted Closing Statement LESS any previous
          reductions pursuant to this CLAUSE (B);

                    (C)  in determining the existence of a breach of the
          Sellers' representations and warranties as to the matters set
          forth in SECTION 3.1(o) for purposes of this SECTION 9.3, no
          effect will be given to items set forth on SCHEDULE 3.1(o) or any
          other Schedule hereto as exceptions to such representations and
          warranties;

                    (D)  the Company's obligations pursuant to
          SECTION 9.3(a)(i)(b) shall terminate as to each Surviving
          Representation when such Surviving Representation 


                                      -57-

<PAGE>

          terminates pursuant to SECTION 3.3 and the Company's obligations
          pursuant to SECTION 9.3(a)(i)(e) shall terminate on the third
          anniversary of the Closing; PROVIDED, HOWEVER, that such obligations
          shall not terminate with respect to any item as to which Buyer shall
          have, prior to the expiration of the applicable period, previously
          made a claim by delivering an Indemnification Notice (as defined in
          SECTION 9.3(c)); and

                    (E)  without expanding liability the Company would
          otherwise have pursuant to this SECTION 9.3(a), the Company shall
          not have any liability under SECTION 9.3(a)(i)(b) or SECTION
          9.3(a)(i)(e) in respect of Losses to the extent arising out of
          Buyer's operation of the Business after the date 45 days after
          the Closing.

               (iii)     The Company's obligations under SECTION
          9.3(a)(i)(b) and  SECTION 9.3(a)(i)(e) in respect of Losses for
          which the Company may be liable in accordance with, and
          notwithstanding the limitations set forth in, SECTION 9.3(a)(ii)
          shall be subject to the following additional limitations:

                    (A)  the Company shall not have any liability for any
          Losses resulting from a claim with respect to any particular
          breach to the extent such Losses are less than $250,000, provided
          that (1) if the Losses related to such claim equal or exceed
          $250,000, then the Company (subject to the other provisions of
          this SECTION 9.3(a)(iii)) shall be liable for Losses related
          thereto only to the extent such Losses exceed $250,000 and (2) in
          each case, any claim or series of claims arising out of or
          relating to the same, substantially similar or substantially
          related facts, circumstances, occurrences, transactions or
          conditions shall constitute one claim with respect to any
          particular breach;

                    (B)  the Company shall not have any liability in
          respect of Buyer Environmental Losses for which the Company may
          be liable notwithstanding the limitation set forth in CLAUSE (A)
          above unless such Buyer Environmental Losses are incurred in
          accordance with SECTION 9.3(f), and in such case the Company
          shall have liability only if the aggregate of all such Buyer
          Environmental Losses for which the Company would, but for this
          CLAUSE (B), be required to indemnify Buyer (excluding without
          limitation Losses for which the Company has no liability as a
          result of CLAUSE (A) above) exceeds on a cumulative basis an
          amount equal to $5,000,000, at which point the Company, subject
          to CLAUSE (E) of this SUBSECTION (a)(iii), shall indemnify Buyer
          for 70% of such Losses, but only to the extent such Losses exceed
          $5,000,000;

                    (C)  the Company shall not have any liability in
          respect of Customer Losses for which the Company may be liable
          notwithstanding the limitation set forth in CLAUSE (A) above
          unless such Customer Losses are incurred in accordance with
          SECTION 9.3(g);

                    (D)  the Company shall not have any liability in
          respect of Customer Losses for which the Company may be liable
          notwithstanding the limitations set forth in CLAUSES (A) and (C)
          above or Other Buyer Losses (other than Losses resulting from the
          breach of the representation and warranty set forth in SECTION
          3.1(b) for which the Company may be liable notwithstanding the
          limitation set forth in CLAUSE (A) above unless the aggregate of
          all such Customer Losses and such Other Buyer Losses for which
          the Company would, but for this CLAUSE (D) be required to
          indemnify Buyer (excluding without limitation Losses for which
          the Company has no liability as a result of CLAUSE (A) above)
          exceeds on a cumulative basis an amount equal to $5,000,000, at
          which point the Company, subject to CLAUSE (E) of this SUBSECTION
          (a)(iii), shall indemnify Buyer for the full amount of such
          Losses but only to the extent such Losses exceed $5,000,000;

                    (E)  the Company shall not have any liability under
          SECTION 9.3(a)(i)(b) or 9.3(a)(i)(e) to the extent the aggregate
          amount of Losses (other than Losses resulting from the breach of
          the representation and warranty set forth in SECTION 3.1(b)) for
          which the Company would otherwise be liable exceeds $75,000,000.

          As used in this Agreement, "BUYER ENVIRONMENTAL LOSSES" shall mean
          Losses of Buyer under SECTION 9.3(a)(i)(b) arising from any breach of
          the Surviving Representations set forth in SECTION 3.1(o), whether or
          not such Losses also arise from any breach of any other Surviving
          Representation, and Losses of Buyer arising under
          SECTION 9.3(a)(i)(e); "CUSTOMER LOSSES" shall mean Losses of Buyer
          under SECTION 9.3(a)(i)(b) arising from any breach of any of the
          Surviving Representations in connection with Liabilities or potential
          Liabilities to customers of the Business or the allocation between the
          Business and any customer of responsibility for Losses or potential
          Losses; and "OTHER BUYER LOSSES" shall mean all Losses of Buyer under
          SECTION 9.3(a)(i)(b) other than Buyer Environmental Losses and
          Customer Losses.

          (b)  BY BUYER AND PARENTS.  Subject to the terms and conditions of
     this SECTION 9.3,  Buyer and Parents, jointly and severally, shall
     indemnify, defend and hold harmless the Sellers, and their respective
     directors, officers, employees and controlling persons, from and against
     all Losses asserted against, resulting to, imposed upon or incurred by any
     such person, directly or indirectly, by reason of or resulting from (i) the
     breach of any covenant of Buyer or Parents, or any one of them, contained
     in this Agreement (including without limitation the other indemnification
     obligations of Buyer and 


                                      -59-

<PAGE>

     Parents provided for in this Agreement); (ii) the breach of the
     representations or warranties of Buyer and/or Parents described in
     SECTION 3.3(b); (iii) failure of Buyer or Parents, or any one of them, to
     pay, perform and discharge, when due, any of the Assumed Liabilities; or
     (iv) subject to any indemnity obligation the Sellers may have in respect of
     the period described in SECTION 9.3(a)(ii)(e), the operation of the
     Business by Buyer following the Closing.  Notwithstanding the foregoing,
     (A) the obligations to indemnify and hold the Company harmless pursuant to
     SECTION 9.3(b)(ii) shall terminate when the representations and warranties
     of Buyer and Parents terminate pursuant to SECTION 3.3; PROVIDED, HOWEVER,
     that such obligations to indemnify and hold harmless shall not terminate
     with respect to any item as to which the Company shall have, prior to the
     expiration of the applicable period, previously made a claim by delivering
     an Indemnification Notice and (B) the amount of Losses for which Buyer and
     Parents would otherwise be liable in respect of any breach of this
     Agreement prior to the Closing shall be reduced (but not below zero) by the

     4.8(b).

          (c)  PROCEDURES RELATING TO INDEMNIFICATION AMONG BUYER, PARENTS AND
     THE SELLERS.  Following the discovery of any facts or conditions which
     could reasonably be expected to give rise to a Loss or Losses for which
     indemnification under this SECTION 9 can be obtained, the party seeking
     indemnification under this SECTION 9 (the "INDEMNIFIED PARTY") shall,
     within a reasonable period of time thereafter, provide written notice to
     the party from whom indemnification is sought (the "INDEMNIFYING PARTY"),
     setting forth the specific facts and circumstances, in reasonable detail,
     relating to such Loss or Losses and the amount of Loss or Losses (or a non-
     binding, reasonable estimate thereof if the actual amount is not known or
     not capable of reasonable calculation) ("INDEMNIFICATION NOTICE");
     PROVIDED, HOWEVER, that failure to give such Indemnification Notice on a
     timely basis shall not affect the indemnification provided hereunder except
     to the extent the Indemnifying Party shall have been actually prejudiced as
     a result of such failure. 

          (d)  PROCEDURES RELATING TO INDEMNIFICATION FOR THIRD PARTY CLAIMS. 
     From and after the Closing, subject to SECTION 9.3(f) with respect to Buyer
     Environmental Losses and subject to SECTION 9.3(g) with respect to Customer
     Losses, and subject to SECTION 8.13 with respect to the Vehma Litigation,

               (i)  In order for an Indemnified Party to be entitled to any
          indemnification provided for under this Agreement arising out of
          or involving a claim or demand made by any other person, firm,
          governmental authority or corporation (a "THIRD PARTY CLAIM"),
          the Indemnified Party must provide an Indemnification Notice to
          the Indemnifying Party relating to the Third Party Claim as
          promptly as reasonably possible after receipt by such Indemnified
          Party of notice of the Third Party Claim.  Thereafter, the
          Indemnified Party shall deliver to the Indemnifying Party, within
          five (5) business days after the Indemnified Party's receipt
          thereof, copies of all notices and documents (including court
          papers) received by the Indemnified 


                                      -60-

<PAGE>

          Party relating to the Third Party Claim; provided, however, that
          failure to provide an Indemnification Notice, or deliver copies of all
          notices and documents, on a timely basis shall not affect the
          indemnification provided hereunder except to the extent the
          Indemnifying Party shall have been actually prejudiced as a result of
          such failure.

               (ii) If a Third Party Claim is made against the Indemnified
          Party, the Indemnifying Party shall be entitled to participate in
          the defense thereof and, if the Indemnifying Party so chooses and
          acknowledges its obligation in writing to indemnify the
          Indemnified Party therefor, to assume the defense thereof with
          counsel selected by the Indemnifying Party and reasonably
          satisfactory to Indemnified Party (except that the Indemnifying
          Party may not so elect without the Indemnified Party's consent
          unless (A) the suit, action, claim, liability or obligation does
          not seek to impose any liability or obligation upon the
          Indemnified Party other than for money damages and (B) such suit,
          action, claim, liability or obligation does not relate to the
          Indemnified Party's relationship with its customers). 
          Notwithstanding any acknowledgment made pursuant to the
          immediately preceding sentence, the Company shall continue to be
          entitled to assert any limitation on its indemnification
          responsibility contained in SECTION 9.3(a)(ii) or (iii).  Should
          the Indemnifying Party so elect to assume the defense of a Third
          Party Claim, the Indemnifying Party shall not be liable to the
          Indemnified Party for legal expenses subsequently incurred by the
          Indemnified Party in connection with the defense thereof.  If the
          Indemnifying Party assumes such defense, then the Indemnified
          Party shall have the right to participate in the defense thereof
          and to employ counsel, at its own expense, separate from the
          counsel employed by the Indemnifying Party, it being understood,
          however, that the Indemnifying Party shall control such defense. 
          The Indemnifying Party shall be liable for the fees and expenses
          of counsel employed by the Indemnified Party for any period
          during which the Indemnifying Party has not assumed the defense
          thereof.  If the Indemnifying Party chooses to defend any Third
          Party Claim, all the parties hereto shall cooperate in the
          defense or prosecution of such Third Party Claim.  Such
          cooperation shall include the retention and (upon the
          Indemnifying Party's request) the provision to the Indemnifying
          Party of records and information which are reasonably relevant to
          such Third Party Claim, and making employees available on a
          mutually convenient basis to provide additional information and
          explanation of any material provided hereunder.  If the
          Indemnifying Party, within a reasonable time after receipt of an
          Indemnification Notice relating to a Third Party Claim, chooses
          not to assume defense of a Third Party Claim or fails to defend
          such Third Party Claim actively and in good faith, the
          Indemnified Party will (upon further notice) have the right to
          undertake the defense, compromise or settlement of such Third
          Party Claim or consent 


                                      -61-

<PAGE>

          to the entry of judgment with respect to such Third Party Claim, on
          behalf of, and for the account and risk of, the Indemnifying Party,
          and the Indemnifying Party shall have no right to challenge the
          Indemnifying Party's defense, compromise, settlement or consent to
          judgment.

          (e)  EXCLUSIVE REMEDY.   Except for rights expressly provided in
     SECTIONS 5.1, 5.2 and 7.1, the indemnification provisions of this
     SECTION 9.3 constitute the sole and exclusive remedy with respect to any
     and all claims relating to the subject matter of this Agreement (or any
     related agreements, except to the extent otherwise expressly set forth
     therein) and no other remedy shall be had in contract, tort or otherwise by
     Buyer, Parents or the Sellers and their respective officers, directors,
     employees, agents, affiliates, attorneys, consultants, successors and
     assigns, all such remedies being hereby expressly waived to the fullest
     extent permitted under applicable law.  Without limitation, the procedures
     set forth in this SECTION 9.3 constitute the sole and exclusive remedy of
     Buyer and the Sellers arising out of any breach or claimed breach of the
     representations and warranties set forth in SECTION 3.1 (other than SECTION
     3.1(y)) made as of the date of this Agreement relating to events occurring
     on or prior to the date hereof that becomes known to the Buyer on or prior
     to the Closing Date.  In furtherance of the foregoing, the Sellers, on the
     one hand, and Buyer and Parents, on the other hand, hereby waive to the
     fullest extent permitted under applicable law, any and all rights, claims
     and causes of action they may have against the Buyer and the Parents, on
     the one hand, the Sellers, or either one of them, on the other hand,
     relating to the subject matter of this Agreement arising under or based
     upon any federal, state, provincial, local or foreign statute, law,
     ordinance, rule or regulation or otherwise, including, without limitation,
     such rights, claims and causes of action Buyer may have against the Sellers
     under CERCLA.  In addition to the foregoing, the amount of indemnification
     obligations of the Sellers, Buyers and Parents set forth in this
     SECTION 9.3 shall be the maximum amount of indemnification obligations set
     forth hereunder and the Sellers, Buyer and Parents shall not be entitled to
     a rescission of this Agreement (or any related agreements) or any further
     indemnification rights or claims of any nature whatsoever, all of which the
     Sellers, Buyer and Parents hereby waive.

          (f)  ENVIRONMENTAL PROCEDURES.  In addition to SECTION 9.3(d), to the
     extent such section is applicable, this SECTION 9.3(f) shall apply to Buyer
     Environmental Losses:

               (i)  The Company shall only be required to indemnify Buyer
          for any Buyer Environmental Losses (A) that arise from or relate
          to any investigation, removal, remedial, cleanup, corrective or
          compliance action ("REMEDIAL ACTION") that (1) is required
          pursuant to Environmental Laws in effect at the time of such
          Remedial Action, or by any governmental authority having
          jurisdiction over such laws whereby such authority purports to be
          acting pursuant to such laws, unless the requirement reasonably
          appears to be outside the authority of the governmental authority
          (a "REQUIRED REMEDIAL ACTION"), or (2) is a Prudent Remedial
          Action (as defined in SUBSECTION (vii)); (B) that exceed any net
          recovery by Buyer or 


                                      -62-

<PAGE>

          its affiliates from any third parties, which recovery Buyer shall
          assess in good faith and, if reasonably determined to be viable by
          Buyer based on advice of counsel, pursue; and (C) if Buyer complies in
          all material respects with its obligations under the remainder of this
          SECTION 9.3(f).  Notwithstanding the foregoing, if any Remedial Action
          is performed (other than by the Company) that is not a Permitted
          Remedial Action (as defined below), then the Company shall have no
          indemnity obligation in respect of Buyer Environmental Losses that are
          discovered or incurred as a consequence of such Remedial Action
          unless, and then only to the extent that, there is an independent
          basis for the Company's indemnity obligation under this SECTION
          9.3(f).  Notwithstanding anything in this SECTION 9.3(f) to the
          contrary, the failure of either party to comply with the obligations
          of this SECTION 9.3(f) shall not affect the indemnification or rights
          provided hereunder except to the extent that the other party shall
          have been actually prejudiced as a result of such failure.  A
          "PERMITTED REMEDIAL ACTION" shall mean a Required Remedial Action or a
          Prudent Remedial Action.

               (ii) During the period that (A) Buyer Environmental Losses
          that would otherwise be subject to indemnification under this
          SECTION 9.3 have not exceeded the sum described in CLAUSE (B) of
          SECTION 9.3(a)(iii) or (B) the Company has no obligation with
          respect to Buyer Environmental Losses due to the limitation set
          forth in CLAUSE (E) of SECTION 9.3(a)(iii), Buyer shall have the
          right to control and direct any Remedial Action.  During the
          period described in CLAUSE (A) above, Buyer shall keep the
          Company reasonably apprised of material developments relating to
          any Remedial Action, including providing the Company with copies
          of material reports, agency notices, correspondence to or from
          governmental agencies and other material documents related to
          such Remedial Action as well as, upon the reasonable request of
          the Company, provide the Company an opportunity to discuss with
          Buyer any investigation proposed to be performed by Buyer prior
          to the start of such investigation.  During the period that Buyer
          Environmental Losses subject to indemnification under this
          SECTION 9.3 have not exceeded the sum described in CLAUSE (B) of
          SECTION 9.3(a)(iii) but exceed eighty percent (80%) of that
          amount, Buyer shall in addition to providing the Company the
          information described in the preceding sentence:  (1) give the
          Company reasonable advance notice of, and a reasonable
          opportunity to participate in, material decisions with respect
          any Remedial Actions controlled or directed by the Buyer and (2) 
          notify the Company regarding any material meetings with agency
          representatives and allow the Company to attend such meetings at
          the Company's expense.  During the period that Buyer
          Environmental Losses that would otherwise be subject to
          indemnification under this SECTION 9.3 exceed the sum described
          in CLAUSE (B) of SECTION 9.3(a)(iii), but do not exceed the
          limitation set forth in CLAUSE (E) of SECTION 9.3(a)(iii), the
          Company shall 


                                      -63-

<PAGE>

          have the right to control and direct any Permitted Remedial Action
          subject to indemnification under this SECTION 9.3, subject to the
          following procedure: (W) prior to controlling and directing such
          matter, the Company shall provide Buyer with written acknowledgment of
          its intention to indemnify Buyer with respect to such Permitted
          Remedial Action in accordance with this Agreement; (X) at any time
          during the Permitted Remedial Action, the Company may, subject to its
          obligation to do so as soon as practicable and with reasonable
          justification, inform Buyer in writing that the Company has determined
          it does not have an obligation to indemnify Buyer with respect to the
          Permitted Remedial Action or any portion thereof; (Y) in such event,
          Buyer may by notice to the Company assume the right to control and
          direct such Permitted Remedial Action (or portion thereof), and in any
          event the Company may cease controlling and directing such Permitted
          Remedial Action (or portion thereof) by notice to Buyer; and (Z) if
          the Company does not have an obligation to indemnify Buyer with
          respect to such Permitted Remedial Action (or portion thereof), then
          Buyer shall reimburse the Company for reasonable expenses the Company
          has incurred in connection therewith; provided, however, that the
          Company shall be responsible for Losses of Buyer to the extent Buyer
          is prejudiced by the failure of the Company to inform Buyer as soon as
          practicable that the Company has determined it does not have an
          obligation to indemnify Buyer.  During the period the Company is
          controlling and directing any Permitted Remedial Action, the Company
          shall: (1) give Buyer reasonable advance notice of, and a reasonable
          opportunity to participate in, material decisions with respect
          thereto, (2) obtain Buyer's consent prior to undertaking any material
          action with respect to such Permitted Remedial Action, PROVIDED THAT
          such consent shall not be unreasonably withheld or delayed, (3)
          provide Buyer with copies of reports, agency notices, correspondence
          to or from governmental agencies and other material documents related
          to such Permitted Remedial Action, and (4) notify Buyer regarding any
          material meetings with agency representatives and allow Buyer to
          attend such meetings at Buyer's expense.  During the period that Buyer
          Environmental Losses exceed the limitation set forth in SECTION
          9.3(a)(iii)(e), and upon the reasonable request of the Company, and at
          the Company's sole cost and expense, Buyer shall provide non-
          privileged information to the Company concerning any Remedial Action
          conducted by Buyer and shall provide the Company with the opportunity
          to discuss any such Remedial Action with Buyer.  To "CONTROL AND
          DIRECT," as used in this SECTION 9.3(f), shall include, without
          limitation, the right (1) to hire and discharge consultants,
          contractors, and experts, (2) obtain any tests, reports, and surveys
          necessary to define and delineate the extent of any contamination or
          noncompliance, (3) contact governmental authorities, make any reports
          to such authorities, submit any remediation or compliance plans to
          such authorities, negotiate with such 


                                      -64-

<PAGE>

          authorities, and otherwise deal with such authorities, (4) prepare the
          work plan for any remediation or correction of noncompliance, and (5)
          conduct or direct any such remediation or correction of noncompliance.
          

               (iii)     To better delineate the respective obligations of
          the Company, on the one hand, and Buyer and Parents, on the other
          hand, with respect to environmental matters, Buyer and Parents
          shall use commercially reasonable best efforts to cause the
          Business to be operated after the Closing Date in material
          compliance with Environmental Laws so as not to knowingly
          compound or aggravate any Environmental Action for which the
          Company may be responsible under this Agreement.  Buyer and
          Parents shall not take action intended to initiate or encourage a
          claim by a third party, including any governmental agency,
          concerning an Environmental Action for which the Company is
          obligated to indemnify Buyer under SECTION 9.3.

               (iv) Buyer and Parents and the Company shall treat
          information concerning any Environmental Action that may be
          subject to indemnification under this SECTION 9.3 as confidential
          information.  Notwithstanding the foregoing, Buyer or the Company
          may disclose such information (A) in confidence to any person
          with whom it proposes to enter into contract for any commercial
          purpose, including financing entities; (B) as required by law,
          including Environmental Laws; (C) in order to attain compliance
          with Environmental Laws; (D) as requested by a court; (E) as
          requested by a governmental agency or other governmental
          authority whereby such authority purports to be acting pursuant
          to Law, unless the requirement reasonably appears to be outside
          the authority of the governmental agency or governmental
          authority; or (F) that is otherwise publicly available.  If
          either Parents or Buyer, on the one hand, or the Company, on the
          other hand, intends to disclose information concerning an
          Environmental Action that may be subject to indemnification under
          this SECTION 9.3, then Buyer or the Company shall notify the
          other party prior to such proposed disclosure pursuant to SECTION
          9.4.

               (v)  The party not controlling and directing a Remedial
          Action shall cooperate in good faith with the party controlling
          and directing the Remedial Action, and vice versa.  Such
          cooperation shall include (A) cooperation in connection with
          efforts to seek reimbursement under applicable governmental
          underground storage tank or other reimbursement programs; (B)
          cooperation in connection with any efforts to seek reimbursement
          under applicable insurance policies relating to the Remedial
          Action; and (C) providing, upon reasonable advance notice,
          reasonable access to the property involved and to all non-
          privileged documents, personnel and other sources of information
          that relate to the Remedial 


                                      -65-

<PAGE>

          Action or are otherwise necessary to effectuate the Remedial Action. 
          While it is controlling and directing any Permitted Remedial Action,
          the Company shall not unreasonably interfere with Buyer's use of any
          property involved or the conduct of Buyer's business.

               (vi) With respect to any Remedial Action conducted at any
          time prior to such time as Buyer Environmental Losses exceed the
          limitation set forth in CLAUSE (E) of SECTION 9.3(a)(iii), (A)
          the parties shall perform such Remedial Action in accordance with
          Environmental Laws in effect as of the time of such Remedial
          Action to allow the continued use of the property for uses
          substantially the same as those for which the Company used the
          property; (B) no Remedial Action shall be undertaken until after
          notice is provided to and approval received from such
          governmental authority with jurisdiction over the Environmental
          Action, if such notice and approval process is required; and (C)
          such Remedial Action shall be performed in a cost-effective and
          reasonable manner.

               (vii)      A "PRUDENT REMEDIAL ACTION" pursuant to SECTION
          9.3(f)(i)(a)(2) shall be a Remedial Action (A) that is undertaken
          in response to Material Facts (as defined below), (B) where Buyer
          has, prior to commencing the Remedial Action, either requested
          and obtained the Company's consent subject to SECTION
          9.3(f)(viii) or received a determination under SECTION 9.5 that
          the Company's consent has been unreasonably withheld or delayed,
          such determination to be made subject to the provisions of
          SECTION 9.3(f)(viii), and (C) where the scope of the Remedial
          Action undertaken is reasonable in relation to the perceived
          risk.  "MATERIAL FACTS" shall mean material facts that represent
          reliable objective evidence indicating that a Hazardous Substance
          is present in a manner that would reasonably be expected to
          present a significant risk to human health or the environment. 
          Buyer acknowledges that the facts specifically disclosed in this
          Agreement or in the Schedules hereto (including documents
          incorporated by reference therein) or otherwise known to Parents
          or Buyer based on the information it has received from Environ
          Corporation as of the date of this Agreement (it being understood
          that prior to the date of this Agreement, Parents and Buyer have
          requested, and Environ Corporation has provided to Parents and
          Buyer, an oral report containing all material information it has
          learned up to the date of this Agreement), do not currently
          represent reliable objective evidence indicating that a Hazardous
          Substance is present in a manner that would reasonably be
          expected to present a significant risk to human health or the
          environment, but the Company acknowledges that there may be
          changes in circumstances relating to such facts, or changes in
          information known to Buyer with respect to such facts, that
          together with such facts could represent reliable objective
          evidence indicating that a Hazardous Substance 



                                      -66-

<PAGE>

          is present in a manner that would reasonably be expected to present a
          significant risk to human health or the environment.

               (viii)     At the time that Buyer requests the consent of
          the Company pursuant to SECTION 9.3(f)(vii)(b), Buyer shall
          disclose to the Company all material information relating to the
          proposed Remedial Action and the basis for conducting the
          Remedial Action.  The Company's consent shall not be unreasonably
          withheld or delayed; however, (1) the reasonableness of the
          Company's decision will be determined based solely upon the
          information disclosed to or known by the Company at the time such
          consent is requested; (2) evidence that a Hazardous Substance may
          be present shall not result in any presumption that the Hazardous
          Substance would reasonably be expected to present a significant
          risk to human health or the environment; and (3) the parties
          recognize that a determination not to further investigate
          evidence indicating that a Hazardous Substance is present may,
          under some circumstances, be a reasonable determination.

          (g)  CUSTOMER PROCEDURES.  Following the Closing, Buyer shall notify
     the Company of the receipt by Buyer or Parents of any Third Party Claim
     involving Customer Losses that may be reasonably expected to exceed the
     limitations set forth in SECTION 9.3(a)(iii)(d).  Buyer and the Company
     shall negotiate in good faith as to the reasonable administration,
     satisfaction and discharge of any such Customer Losses in a commercially
     reasonable manner, and Buyer shall administer, satisfy and discharge such
     Customer Losses only in a manner approved in all material respects by the
     Company in advance, which approval shall not be unreasonably withheld or
     delayed.  Buyer shall as soon as practicable notify the Company as to
     material developments with respect to such Third Party Claims.

          9.4. NOTICES.  Except as otherwise set forth in this Agreement, all

          9.5. RESOLUTION OF DISPUTES.

          (a)  NEGOTIATION.  In the event of any dispute or disagreement between
     the Sellers and Buyer or Parents as to the interpretation of any provision
     of, or the performance of obligations under, this Agreement (except for
     such disputes or disagreements regarding the Closing Statement which shall
     be resolved exclusively pursuant to SECTION 2.4(d)), the matter, upon
     written request of either party, shall be referred to representatives of
     the parties for decision, each party being represented by a senior
     executive officer who has no direct operational responsibility for the
     matters contemplated by this Agreement (the "REPRESENTATIVES").  The
     Representatives shall promptly meet in a good faith effort to resolve the
     dispute.  If the Representatives do not agree upon a decision within thirty
     (30) calendar days after reference of the matter to them, Buyer and the
     Sellers shall be free to exercise the remedies available to them under this
     SECTION 9.5.

          (b)  ARBITRATION.  Any dispute, controversy or claim arising out of or
     relating to this Agreement or the negotiation hereof or entry hereunto or
     any Contract entered into pursuant hereto or the performance by the parties
     of its or their terms shall be settled by binding arbitration administered
     by the Center for Public Resources in accordance with its then prevailing
     Rules for Non-Administered Arbitration of Business Disputes (except as
     otherwise provided herein).  The arbitration shall be held in Milwaukee,
     Wisconsin.  This SECTION 9.5 shall be construed and enforced in accordance
     with the Federal Arbitration Act, notwithstanding any other choice of law
     provision in this Agreement.  Notwithstanding the foregoing, Buyer may, in
     its discretion, apply to a court of competent jurisdiction for equitable
     relief from any violation or threatened violation of the covenants of the
     Sellers, or any one of them, under SECTION 8.3.  Such an application shall
     not be deemed a waiver of the right to compel arbitration pursuant to this
     SECTION 9.5.  

          (c)  ARBITRATORS. If the matter in controversy (exclusive of attorney
     fees and expenses) shall appear, as at the time of the demand for
     arbitration, to exceed $2,000,000, then the panel to be appointed shall
     consist of three (3) neutral arbitrators; otherwise, one neutral
     arbitrator. 

          (d)  PROCEDURES; NO APPEAL.  The arbitrator(s) shall allow such
     discovery as the arbitrator(s) determine appropriate under the
     circumstances and shall resolve the dispute as expeditiously as
     practicable, and if reasonably practicable, within one hundred twenty (120)
     days after the selection of the arbitrator(s).  The arbitrator(s) shall
     give the parties written notice of the decision, with the reasons therefor
     set out, and shall have thirty (30) days thereafter to reconsider and
     modify such decision if any party so requests within ten (10) days after
     the decision.  Thereafter, the decision of the arbitrator(s) shall be
     final, binding, and nonappealable with respect to all persons, including
     (without limitation) persons who have failed or refused to participate in
     the arbitration process.


                                      -69-

          (e)  AUTHORITY.  The arbitrator(s) shall have authority to award
     relief under legal or equitable principles, including interim or
     preliminary relief, and to allocate responsibility for the costs of the
     arbitration and to award recovery of attorneys fees and expenses in such
     manner as is determined to be appropriate by the arbitrator(s).
     Notwithstanding the foregoing, the arbitrator(s) shall not be empowered to
     award any past consequential damages, loss profits (except as provided in
     the penultimate sentence of SECTION 9.3(a)(i)) or punitive damages in
     connection with any dispute between Buyer and Parents, on the one hand, and
     the Sellers, on the other hand, or either one of them, arising out of or
     relating in any way to this Agreement or the transactions arising
     hereunder, and each party hereby irrevocably waives any right to recover
     such damages.

          (f)  ENTRY OF JUDGMENT.  Judgment upon the award rendered by the
     arbitrator(s) may be entered in any court having in personam and subject
     matter jurisdiction.  The Sellers, Buyer and Parents hereby submit to the
     in personam jurisdiction of the federal and state courts in Wisconsin, for
     the purpose of confirming any such award and entering judgment thereon.

          (g)  CONFIDENTIALITY.  All proceedings under this SECTION 9.5, and all
     evidence given or discovered pursuant hereto, shall be maintained in
     confidence by all parties and by the arbitrator or arbitrators.

          (h)  CONTINUED PERFORMANCE.  The fact that the dispute resolution
     procedures specified in this SECTION 9.5 shall have been or may be invoked
     shall not excuse any party from performing its obligations under this
     Agreement, and during the pendency of any such procedure all parties shall
     continue to perform their respective obligations in good faith.

          (i)  TOLLING.  All applicable statutes of limitation shall be tolled
     while the procedures specified in this SECTION 9.5 are pending.  The
     parties will take such action, if any, required to effectuate such tolling.

          9.6. ENTIRE AGREEMENT.  This Agreement (including the Exhibits and
schedules hereto), the Access Agreement and the letter agreement entered into
between Tower and the Company dated October 18, 1996 constitute the entire
agreement between the parties hereto and supersede all prior agreements and
understandings, oral and written, between the parties hereto with respect to the
subject matter hereof.

          9.7. BINDING EFFECT; BENEFIT.  This Agreement shall inure to the
benefit of and be binding upon the parties hereto and their respective
successors and assigns.  Nothing in this Agreement, expressed or implied, is
intended to confer on any person other than the parties hereto or their
respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement.

          9.8. BULK SALES LAW.  Buyer and the Sellers each agree to waive
compliance by the other with the provisions of the bulk sales law of any
jurisdiction, and the Sellers agree to indemnify Buyer for any Losses arising
from such non-compliance other than in respect of Losses constituting Assumed
Liabilities.

          9.9. ASSIGNABILITY.  This Agreement shall not be assignable by the
Sellers without the prior written consent of Buyer or by Buyer or Parents
without the prior written consent of the Sellers, provided that (a) Buyer may
assign its rights and delegate its duties hereunder for collateral security
purposes to its lenders providing the Financing and (b) Buyer may assign its
rights and delegate its duties hereunder to an affiliate or affiliates, so long
as Parents, Buyer and such affiliate agree to be jointly and severally liable
for all obligations hereunder, but any such assignments shall be subject to all
of the terms and conditions applicable to such rights and obligations under this
Agreement.

          9.10.     AMENDMENT; WAIVER.  This Agreement may be amended,
supplemented or otherwise modified only by a written instrument executed by the
parties hereto.  No waiver by either party of any of the provisions hereof shall
be effective unless explicitly set forth in writing and executed by the party so
waiving.  Except as provided in the preceding sentence, no action taken pursuant
to this Agreement, including without limitation any investigation by or on
behalf of any party, shall be deemed to constitute a waiver by the party taking
such action of compliance with any representations, warranties, covenants, or
agreements contained herein, and in any documents delivered or to be delivered
pursuant to this Agreement and in connection with the Closing hereunder.  The
waiver by any party hereto of a breach of any provision of this Agreement shall
not operate or be construed as a waiver of any subsequent breach.

          9.11.     SCHEDULES.  Any fact or item disclosed on any Schedule to
this Agreement shall be deemed disclosed on all other Schedules to this
Agreement to which such fact or item may reasonably apply so long as such
disclosure is in sufficient detail to enable a party hereto to identify the
facts or items to which it applies.  Any fact or item disclosed on any Schedule
hereto shall not by reason only of such inclusion be deemed to be material and
shall not be employed as a point of reference in determining any standard of
materiality under this Agreement.  Prior to the Closing, the Sellers shall have
the right to supplement, modify or update the Schedules hereto to reflect
changes in the ordinary course of the Business prior to the Closing; PROVIDED,
HOWEVER, that any such supplements, modifications or updates shall be subject to
Buyer's rights under SECTION 5.1(A).

          9.12.     KNOWLEDGE.  The term "KNOWLEDGE" when used in the phrases
"to the knowledge of the Sellers" or "Sellers have no knowledge" or words of
similar import shall mean, and shall be limited to, the actual knowledge of the
individuals listed with respect to the Sellers on SCHEDULE 9.12 and shall only
include their actual knowledge obtained in their respective capacities with the
Sellers, without any duty to investigate; provided, however, that the knowledge
of the Sellers as of a particular time after the Closing for purposes of SECTION
9.3(f)(vii) shall not be deemed to include the knowledge of any individual who
is not employed by the Sellers or any of their affiliates as of such time.

          9.13.     SECTION HEADINGS; TABLE OF CONTENTS.  The Section headings
contained in this Agreement and the Table of Contents to this Agreement are for
reference purposes only and shall not affect the meaning or interpretation of
this Agreement.

          9.14.     SEVERABILITY.  If any provision of this Agreement shall be
declared by any court of competent jurisdiction to be illegal, void or
unenforceable, then all other provisions of this Agreement shall not be affected
and shall remain in full force and effect.

          9.15.     NO STRICT CONSTRUCTION.  Notwithstanding the fact that this
Agreement has been drafted or prepared by one of the parties, each of the
parties confirms that both it and its counsel have reviewed, negotiated and
adopted this Agreement as the joint agreement and understanding of the parties,
and the language used in this Agreement shall be deemed to be the language
chosen by the parties hereto to express their mutual intent, and no rule of
strict construction shall be applied against any person.

          9.16.     COUNTERPARTS.  This Agreement may be executed in any number
of counterparts, each of which shall be deemed to be an original and all of
which together shall be deemed to be one and the same instrument.

construed in accordance with, the laws of the State of Delaware without regard
to conflicts of laws principles thereof.
