ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On May 31, 1996, pursuant to the Stock Purchase Agreement dated May 31,
1996 among the Registrant, the Registrant's wholly owned subsidiary, R.J. Tower
Corporation, a Michigan corporation ("Tower"), and MascoTech, Inc., a Delaware
corporation ("MascoTech"), Tower acquired from MascoTech all of the issued and
outstanding capital stock of MascoTech Stamping Technologies, Inc., a Delaware
corporation ("MSTI"). MSTI's assets are located in Rochester Hills, Michigan,
Kendallville, Indiana, Upper Sandusky, Ohio and Bluffton, Ohio.

     MSTI is engaged in the design, manufacturing, marketing and sales of
stampings used in chassis and suspension systems by North American car, mini-
van, and light truck manufacturers.  The Registrant intends to continue to use
MSTI's assets in substantially the same manner as they were used prior to the
acquisition.

     The aggregate purchase price of all of the issued and outstanding capital
stock of MSTI was approximately $79 million in cash, stock, and warrants.
Contingent consideration of up to $30 million is payable over the next three
years if MSTI achieves certain operating results over that period (including a
7% promissary note issued in favor of MascoTech payable approximately one year
following the acquisition in an aggregate principal amount of $5.0 million,
subject to reduction based on the operating profits of the MSTI facilities for 
the 12 months following the acquisition). The purchase price was funded through
the issuance by Tower of $65 million of Senior Secured Notes and through
borrowings under Tower's First Amendment to Third Amended and Restated Credit
Agreement (the "Credit Agreement") with Comerica Bank, as agent. The Credit
Agreement provides a revolving credit facility of $75 million and letters of
credit of approximately $47.4 million. The aggregate purchase price was arrived
at through arm's length negotiations between the parties.

                            REPORT OF INDEPENDENT 
                              PUBLIC ACCOUNTANTS



To MascoTech Stamping Technologies, Inc.:

We have audited the accompanying statements of net assets acquired of MascoTech
Stamping Technologies, Inc. as of December 31, 1994 and 1995, and the related
statements of revenues and expenses and cash flows for each of the three years
in the period ended December 31, 1995.  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
MascoTech Stamping Technologies, Inc. acquired pursuant to the Stock Purchase
Agreement discussed in Note 1 and are not intended to be a complete presentation
of MascoTech Stamping Technologies, Inc.'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 acquired of MascoTech Stamping
Technologies, Inc. pursuant to the Stock Purchase Agreement discussed in Note 1
as of December 31, 1994 and 1995, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1995 in
conformity with generally accepted accounting principles.

                     MASCOTECH STAMPING TECHNOLOGIES, INC.
                         NOTES TO FINANCIAL STATEMENTS

               (INFORMATION AS OF AND FOR THE THREE MONTH PERIODS
                  ENDED MARCH 31, 1995 AND 1996 IS UNAUDITED)


1.   ORGANIZATION AND BASIS OF PRESENTATION:

     During the periods presented, MascoTech Stamping Technologies, Inc. (MSTI -
     a Delaware corporation) was a wholly owned subsidiary of MascoTech, Inc.
     (MascoTech or the Parent). On May 31, 1996, all of the outstanding common
     stock of the Company was acquired by R.J. Tower Corporation (R.J. Tower), a
     wholly owned subsidiary of Tower Automotive, Inc. (See Note 7) pursuant to
     the terms of a Stock Purchase Agreement (the Acquisition.)  Prior to the
     Acquisition and during the years presented, MSTI divested of certain
     operations.  The accompanying financial statements reflect the assets
     acquired and liabilities assumed, revenues and expenses and cash flows of
     the operations conducted by MSTI acquired by R.J. Tower as of the date of
     the Acquisition. This presentation is intended to provide a more meaningful
     representation of the historical financial information of the acquired
     operations and is not intended to represent a presentation of the financial
     position and results of operations of MSTI. The operations included in the
     accompanying financial statements are referred to herein as the Company.
     The accompanying financial statements have not been adjusted to reflect the
     effects of the Acquisition.

     The accompanying statement of net assets acquired as of March 31, 1996, and
     the statements of revenues and expenses and cash flows for the three month
     periods ended March 31, 1995 and 1996, are unaudited.  In the opinion of
     management, such financial statements include all adjustments, consisting
     solely of normal recurring adjustments, necessary for a fair presentation
     of results for these interim periods.  The revenues and expenses for the
     three-month period ended March 31, 1996 are not necessarily indicative of
     results to be expected for the entire year.

     The Company is a manufacturer and supplier of stamped chassis and
     suspension components and assemblies for the North American automotive
     industry and has three manufacturing facilities.

2.   SIGNIFICANT ACCOUNTING POLICIES:

     Arrangements with Affiliates:

     During the periods presented, the Company provided certain services to
     other entities which were affiliated through common ownership or which had
     previously been wholly owned subsidiaries of MSTI that were sold prior to
     the Acquisition.  One of these affiliates was Trylon Corporation which was
     acquired by R.J. Tower in January 1996.  These services consisted of the
     performance of accounting and treasury functions, maintenance of management
     information systems, product engineering and assistance with other
     administrative matters.  In addition, a division of the Company designed,
     developed and manufactured customer tooling on behalf of these affiliates
     for use in their manufacturing operations.  Certain other services were
     provided to the Company and these affiliates by MascoTech and its
     affiliate, Masco Corporation (Masco - see Note 6 for further discussion
     of these arrangements).

     Through the course of providing services to these affiliates, information
     related to amounts receivable from customers, obligations to vendors and
     costs incurred in the development and manufacture of customer tooling were
     maintained by MSTI on a commingled basis during certain periods.  In the
     preparation of the accompanying financial statements, it was determined
     that it was not practicable to specifically identify 

                                      F-5
<PAGE>
 
     such amounts which related solely to the Company. Accordingly, the amounts
     presented in the accompanying financial statements related to these matters
     reflect estimates, which management believes were reasonable and
     appropriate in the circumstances, of the portion of such balances which
     were associated with the acquired operations. Management does not believe
     that such estimates would differ materially from actual amounts had it been
     practicable to specifically identify such actual amounts.

     Inventories:

     Inventories are valued at the lower of first-in, first-out cost or market.
     Inventories consisted of the following (in thousands):

</TABLE> 

     Prepaid Customer Tooling:

     Prepaid 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 entitled to be reimbursed by the customer for the
     cost of the tooling, at which time the tooling becomes the property of 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:

               Buildings and improvements  20 to 40 years
               Machinery and equipment      3 to 15 years

     Accelerated depreciation methods are used for tax reporting purposes.

     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.

     Goodwill and Other Assets:

     Goodwill represents the excess of consideration paid over the fair value of
     the net assets acquired in the Company's previous acquisitions and is being
     amortized on a straight-line basis over 40 years.  Goodwill is presented
     net of accumulated amortization of $16,244,000, $17,882,000 and $18,292,000
     at December 31, 1994 and 1995 and March 31, 1996.  At each balance sheet
     date, management assesses whether there has been a permanent impairment
     of goodwill by comparing anticipated undiscounted future cash flows from
     operating activities with the carrying amount of goodwill. Based on this
     assessment, there was no impairment of goodwill at December 31, 1995. 
     Other assets were not significant during any period presented.

     Income Taxes:

     The Company accounts for income taxes under the liability method, whereby

                                      F-6
<PAGE>
  
     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.

     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 accounts receivable, inventories and customer tooling
     balances and to the determination of account balances which were maintained
     by the Company on a commingled basis with certain affiliates, as discussed
     above.  The ultimate results could differ from those estimates.

3.   MAJOR CUSTOMERS:

     The Company sells its products directly to automobile manufacturers and
     their direct suppliers.  Following is a summary of customers that accounted
     for more than 10% of revenues:

     Chrysler        6%       7%       9%        13%         10%

</TABLE> 

     Receivables from these customers represented 74% and 78% of total accounts
     receivable at December 31, 1994 and 1995, and 67% at March 31, 1996.

4.   INCOME TAXES:

     MSTI's results of operations are included in the consolidated federal
     income tax returns of MascoTech while separate income tax returns are filed
     for state income tax purposes.  As a result, all tax payments are made by
     MascoTech.  The provisions for income taxes in the accompanying statements
     of revenues and expenses for the years ended December 31, 1993, 1994, and
     1995, and for the three-month periods ended March 31, 1995 and 1996 were
     computed on a separate-company basis as if the Company had filed separate
     federal tax returns.

     The income tax provision (benefit) consisted of the following (in
     thousands):

5.   COMMITMENTS AND CONTINGENCIES:

     Employee Benefit Plans:

     During the periods presented, employees of the Company were eligible to
     participate in a variety of employee benefit plans sponsored by the Parent.
     Participation in these plans was subject to certain eligibility conditions.

     The Parent sponsors retirement savings plans which provide qualified
     employees the opportunity to defer a portion of their salary on a before-
     tax basis.  The Company may match a portion of these contributions, at its
     discretion.  No matching contributions were made during any period
     presented in the accompanying financial statements.

     The Company may also make discretionary contributions on behalf of certain
     of its salaried employees to profit-sharing plans sponsored by the Parent.
     Such contributions which have been charged to expense in the accompanying
     statements of revenues and expenses were $288,000 during the year ended
     December 31, 1995 and $94,000 and $117,000 during the three-month periods
     ended March 31, 1995 and 1996.  Such amounts were not significant during
     the other periods presented.

     Certain of the Company's employees also participate in plans sponsored by
     the Parent which provide for future benefit payments which are determined
     on a formula basis dependent upon such factors as years of service and
     specified benefit levels.  The Parent, as sponsor of these plans, has
     ultimate responsibility for payment of these benefits and charges the
     Company a predetermined amount related to those employees of the Company
     that participate in these plans.  Amounts charged to the Company relative
     to these plans which have been reflected as expense in the accompanying
     statements of revenues and expenses were $525,000, $689,000 and $675,000
     during the years ended December 31, 1993, 1994 and 1995, and $170,000 and
     $185,000 during the three month periods ended March 31, 1995 and 1996.

     In connection with the Acquisition, all benefits earned by the Company's
     employees through the acquisition date under the plans described above
     remained the responsibility

                                      F-8
<PAGE>
  
     of MascoTech and those employees are eligible to participate in the
     employee benefit plans, if any, maintained by the Company following the
     acquisition.

     In addition to the above plans, certain hourly and salaried
     employees at one of the Company's manufacturing facilities are entitled to
     receive medical and life insurance benefits upon their retirement, if they
     meet specified eligibility requirements, under the terms of a plan
     sponsored by MascoTech.  During all periods presented in the accompanying
     financial statements, MascoTech was responsible for providing these
     benefits.  Accordingly, no liability has been recognized in the financial
     statements of the Company associated with these obligations.  In connection
     with the Acquisition, R.J. Tower agreed to assume this obligation and will
     record it as part of the purchase.  As of December 31, 1995, the estimated
     accumulated benefit obligation associated with these employees was not
     significant.

     Environmental and Legal Matters:

     Due to the nature of its business, the Company may, from time to
     time, be exposed to potential liabilities to clean up environmental
     contaminants.  In addition, the Company is periodically involved in legal
     proceedings during the ordinary course of business.  In the opinion of
     management, such matters are not expected to have a material impact on the
     Company's future operating results or financial position.

6.   RELATED PARTY TRANSACTIONS:

     Prior to the acquisition of the Company by R.J. Tower, Masco and the Parent
     provided certain administrative services to the Company, and the Company
     engaged in certain transactions with Masco, MascoTech and its subsidiaries.
     Such services and transactions included the following:

     .  Cash management functions related to the collection of amounts
        receivable from customers and the funding of payments made to vendors.

     .  The purchase and sale of certain manufactured products between the
        Company and other MascoTech operations.

     .  Participation in insurance programs and selected employee benefit plans
        which were sponsored by the Parent.

     Charges for the Company's respective share of the amounts related to its
     participation in common programs with the Parent and its subsidiaries are
     reflected as a component of operating expenses in the accompanying
     statements of revenues and expenses.  Under the terms of these 
     arrangements, the Company pays fees to MascoTech, and MascoTech, in turn,
     pays fees to Masco for services such as those discussed above. Such fees, 
     which are determined principally as a percentage of sales, totaled
     $1,791,000, $2,922,000 and $3,572,000 during the years ended December 31,
     1993, 1994 and 1995, and $867,000 and $617,000 during the three month
     periods ended March 31, 1995 and 1996.

7.   ACQUISITION BY R.J. TOWER:

     Effective May 30, 1996, all of the outstanding common stock of the Company
     was acquired by R.J. Tower (see discussion in Note 1).  Terms of the Stock
     Purchase Agreement provided for the purchase of the common stock for
     consideration of approximately $55 million in cash, 785,000 shares of Tower
     Automotive, Inc. common 

                                      F-9
<PAGE>
 
     stock, a one-year promissory note in the amount of $5 million bearing
     interest at 7% and warrants to acquire 200,000 common shares of Tower
     Automotive, Inc. at $18 per share. Payment of the one-year promissory note
     is contingent upon the Company achieving certain operating results during
     the first year following the acquisition. In addition, MascoTech may
     receive additional cash consideration of up to $25 million if the Company
     achieves certain operating results during the three years following the
     completion of the acquisition. Subsequent to this acquisition, the
     operations of the Company will be continued by R.J. Tower. The acquisition
     of the Company will be accounted for by R.J. Tower as a purchase and,
     accordingly, the Company's assets and liabilities will be recorded at their
     fair values as of the acquisition date.

                   UNAUDITED PRO FORMA FINANCIAL STATEMENTS
 
  The following Unaudited Pro Forma Statement of Operations for the year ended
December 31, 1995 gives effect to Tower's acquisition of Trylon Corporation
(including related financing transactions), which was completed on January 16,
1996 and the acquisition of MSTI (including related financing transactions) as
if such transactions had occurred on January 1, 1995. The following Unaudited
Pro Forma Statement of Operations for the three months ended March 31, 1996
gives effect to the acquisition of MSTI (including related financing
transactions) as if such transaction had occurred on January 1, 1996. Tower
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 Registrant's results of operations for
the three-month period ended March 31, 1996.
 
  The information included in the Unaudited Pro Forma Balance Sheet as of
March 31, 1996 reflects the acquisition of MSTI (including related financing
transactions) as if such transaction occurred on such date. The historical
financial statements of the Registrant as of March 31, 1996 already reflect
the acquisition of Trylon.
 
  In connection with the acquisition of MSTI, Tower has committed to make
additional earn-out payments if certain operating targets are achieved by the
MSTI facilities in the first three years following the acquisition. The
Unaudited Pro Forma Financial Statements do not include any amounts related to
such payments as a result of their contingent nature.
 
  The unaudited pro forma financial data presented herein are based on the
assumptions and adjustments described in the accompanying notes. The Unaudited
Pro Forma Statements of Operations do not purport to represent what the
Registrant'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 Registrant 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 Registrant, Trylon and MSTI, including the notes thereto.

             NOTES TO UNAUDITED PRO FORMA STATEMENTS OF OPERATIONS
 
(1) Represents the results of operations of the Registrant for the year ended
    December 31, 1995. Beginning in 1996, the Registrant began classifying
    certain engineering expenses that were previously classified as selling,
    general and administrative expenses as cost of sales. These engineering
    expenses incurred in 1995 have been reclassified to cost of sales to be
    consistent with the 1996 presentation. This reclassification had no effect
    on previously reported operating income or net income.
(2) Represents the results of operations of Trylon for the year ended December
    31, 1995. The Registrant 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 Unaudited Pro Forma Consolidated Statement of Operations for the three
    months ended March 31, 1996.
(3) Represents the change in depreciation expense resulting from adjustments
    to the depreciable lives of property, plant and equipment of Trylon 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 date of acquisition.
(4) Represents the net periodic postretirement benefit cost associated with
    the postretirement benefit obligation assumed in connection with the
    acquisition of MSTI.
(5) Represents amortization of goodwill arising from the acquisition of
    Trylon, net of amortization of goodwill previously recorded by Trylon
    which has been eliminated. Goodwill will be amortized on a straight-line
    basis over a forty year period.
(6) Represents amortization of goodwill arising from the acquisition of MSTI,
    net of amortization of goodwill previously recorded by MSTI 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 acquisition of Trylon. Interest expense was
    calculated using the weighted average interest rate on the borrowings
    incurred to fund the acquisition.
(8) Represents incremental interest expense arising from indebtedness incurred
    in connection with the acquisition of MSTI. Interest expense was
    calculated using the weighted average interest rate on the borrowings
    incurred to fund the acquisition.
(9) To adjust the provision for income taxes on a pro forma basis to reflect
    the Company's incremental tax rate of 40%.
(10) Represents the shares of Common Stock issued to MascoTech in connection
     with the acquisition of MSTI.
(11) Represents the change in depreciation expense resulting from adjustments
     to the depreciable lives of property, plant and equipment of MSTI 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 date of acquisition.

(5) To record Company management's preliminary estimate of reserves to be
    established in connection with the acquisition of MSTI including $1,300 of
    losses to be incurred on sale of products which have costs in excess of
    selling prices, $5,800 of costs to be incurred to rationalize certain
    facilities of MSTI, $300 of employee severance and related costs and
    $3,100 for the estimated accumulated benefit obligation associated with
    assumed post retirement medical and life insurance benefits of certain
    MascoTech employees. These reserves have been established based on
    preliminary estimates. Management does not believe the actual amounts to
    be incurred will be materially different than the estimated amounts.
(6) To reflect the $19,134 value of the Common Stock and $2,000 value of the
    warrants issued to MascoTech in connection with the acquisition of MSTI.
    The warrants were valued using the Black-Scholes option pricing model.
(7) To eliminate the historical stockholder's investment of MSTI.

                            STOCK PURCHASE AGREEMENT


     This Stock Purchase Agreement (this "Agreement") is made as of May 31, 1996
by and among MascoTech, Inc., a Delaware corporation ("Seller"), Tower
Automotive, Inc., a Delaware corporation ("Parent") and R.J. Tower Corporation,
a Michigan corporation and a wholly owned subsidiary of Parent ("Buyer").

     The authorized capital stock of MascoTech Stamping Technologies, Inc., a
Delaware corporation (the "Company"), consists of 1,000 shares of common stock,
par value $1.00 per share, of which 1,000 shares are issued and outstanding
(collectively, the "Company Stock").  Seller owns beneficially and of record
100% of the outstanding Company Stock.

     Buyer desires to acquire from Seller, and Seller desires to sell to Buyer,
all of the shares of Company Stock owned by Seller.

     NOW, THEREFORE, the parties hereto, intending to be legally bound, agree as
follows:


                                 ARTICLE I

                           PURCHASE AND SALE OF STOCK
                           --------------------------

     1.1  PURCHASE AND SALE.  On and subject to the terms and conditions set
forth in this Agreement, on the Closing Date (as defined), Buyer will purchase
from Seller, and Seller will sell and transfer to Buyer, all of the shares of
Company Stock owned by the Seller, free and clear of all liens, charges,
security interests and other encumbrances.

     1.2  PURCHASE PRICE.   The aggregate purchase price to be paid to Seller
for the Company Stock (the "Purchase Price") will consist of the Cash Purchase
Price, the Shares, the Note, the Warrant (as each of such terms is defined
below), and the Earnout Amount (as defined in Section 1.4).

     (a) Cash Purchase Price. Buyer shall pay to Seller $55 million in
immediately available funds, as adjusted pursuant to Section 1.3 (a) below (the
"Cash Purchase Price").

     (b) Shares. Parent shall transfer to Seller 785,000 shares of Parent's
Common Stock, par value $.01 per share ("Parent's Common") (the "Shares").

     (c) Note.  Buyer shall issue to Seller a promissory note bearing interest
at 7% per annum (the "Note") in the form of Exhibit A attached hereto, in the
principal amount of $5 million, as may be adjusted pursuant to the terms thereof
(such principal (as adjusted) plus interest, the "Note Amount").

     (d) Warrant.  Parent shall issue to Seller a four year warrant (the
"Warrant") in the form of Exhibit B attached hereto, for 200,000 shares of
Parent's Common (the "Warrant Shares") at an exercise price of $18 per share.
<PAGE>
 
     1.3  ADJUSTMENTS TO CASH PURCHASE PRICE.

     (a) As promptly as practicable after the Closing Date, Buyer and Seller
shall in good faith jointly prepare a statement of working capital of the
Company as of the close of business on the Closing Date (the "Closing Statement
of Working Capital") for the purpose of establishing the Actual Closing Working
Capital. For purposes hereof, "Actual Closing Working Capital" means the book
value of the Company's total current assets relating to the Company's operations
at Rochester Hills, Michigan (including the GEI tooling operations),
Kendallville, Indiana, Bluffton, Ohio and Upper Sandusky, Ohio (the "Company
Operations") (excluding cash to the extent retained by Seller through the
Closing Date, prepaid launch costs, and those accounts receivable and tooling
in process items as set forth or described on Schedule 1.3(a) attached hereto
(the "Carved-Out Assets Schedule")) less the Company's total current liabilities
relating to the Company Operations (excluding any current liability which is
retained or discharged by Seller after the Closing including, without
limitation, federal and state income taxes, workers' compensation obligations
and intercompany accounts and excluding those reserves established in respect of
those assets which are set forth or described on the Carved-Out Asset Schedule)
(which amount may be a negative number), determined from the Closing Statement
of Working Capital as of 11:59 p.m. on the Closing Date. The Closing Statement
of Working Capital shall (i) be prepared in accordance with generally accepted
accounting principles, consistently applied ("GAAP") regardless of whether GAAP
was applied in prior periods (other than (A) with respect to vacation accruals
for salaried employees for which no accruals shall be made, and (B) with respect
to the current portion of deferred taxes for which no accruals shall be made),
(ii) reflect all items and adjustments regardless of materiality, and (iii)
reflect reserves determined in accordance with GAAP (other than those reserves
described in the parenthetical set forth in clause (i) above).

     (b) If Buyer and Seller are unable to come to a mutual agreement with
respect to any item on the Closing Statement of Working Capital within 60
business days after the Closing Date, Buyer and Seller shall jointly retain the
independent accounting firm of Price Waterhouse, LLP (the "Auditor") to resolve
any such disagreements in accordance with subsection (c) below; provided,
however, that Seller or Buyer, as the case may be, shall within 3 business days
following the retention of the Auditor pay to Buyer or Seller, as the case may
be, any amount determined pursuant to subsection (d) below which is not subject
to dispute.

     (c) Buyer and Seller shall direct the Auditor to render a determination
within 25 days of its retention and Buyer and Seller shall use their best
efforts to cause the Auditor to resolve all disagreements over individual line
items as soon as possible. The Auditor shall consider only those items and
amounts in the Closing Statement of Working Capital which Buyer and Seller are
unable to resolve. The determination of the Auditor shall be conclusive and
binding upon Buyer and Seller. The fees and expenses of the Auditor shall be
borne one-half by Buyer and one-half by Seller.

     (d) If Actual Closing Working Capital exceeds $12.6 million, Buyer shall
within 3 business days pay to Seller the amount of such excess in immediately
available funds. If Actual Closing Working Capital is less than $12.6 million,
Seller shall within 3 business days pay to Buyer

                                      -2-
<PAGE>
 
in immediately available funds the amount of such shortfall. All amounts owed
pursuant to this subsection (d) shall include interest, from the Closing Date to
the date of payment, at the Prime Rate (as defined) calculated on the basis of a
365-day year.

     1.4 DETERMINATION OF EARNOUT AMOUNT.

     (a) In accordance with this Section 1.4, Buyer shall pay the Earnout Amount
(as defined below) achieved in each of the 12-month periods ending on May 31,
1997, 1998 and 1999 (each such 12-month period, an "Anniversary Period") to
Seller. The "Earnout Amount" for each Anniversary Period means an amount equal
to (i) two (2) multiplied by (ii) the excess (but not the shortfall), if any, of
(A) Plant Profits (as defined below) for such Anniversary Period, over (B) $24
million; provided that in the event Plant Profits for such Anniversary Period
exceeds $33 million then the Earnout Amount for such Anniversary Period shall be
equal to $30 million (subject to reduction pursuant to Section 1.4(b) below).

     (b) Notwithstanding anything to the contrary set forth in this Agreement,
in no event shall Buyer be obligated pursuant to this Section 1.4 to pay to
Seller an aggregate amount in excess of (i) $30 million minus (ii) the sum of
(A) any amount previously paid pursuant to this Section 1.4 plus (B) the
principal amount paid under the Note.

     (c) Within sixty (60) days after the end of each Anniversary Period, Buyer
will prepare and deliver to Seller an accounting of the Plant Profits and the
Earnout Amount for such Anniversary Period (the "Earnout Statement") together
with the Earnout Amount (if any) for such Anniversary Period in immediately
available funds. Upon delivery of the Earnout Statement, Buyer will permit
Seller and its representatives access to the Company's and, if applicable, the
Buyer's financial books and records during normal business hours for the purpose
of reviewing such accounting. If Seller disagrees with any item on the Earnout
Statement, Seller shall notify Buyer in writing of such disagreement within
thirty (30) days after Seller's receipt thereof (such notice setting forth the
basis for such disagreement in reasonable detail) and Buyer and Seller shall
thereafter negotiate in good faith to resolve any such disagreements. If Buyer
and Seller are unable to resolve any such disagreements within thirty (30) days
after such Seller's notice, Buyer and Seller shall jointly retain the Auditor to
resolve the disagreements in accordance with Section 1.3(b) above (substituting
the words "Earnout Statement" for the words "Closing Statement of Working
Capital" therein). Within five business days after the Auditor notifies Buyer of
the Auditor's determination that Buyer owes an additional amount to Seller
pursuant to this Section 1.4 for such Anniversary Period, Buyer shall pay such
additional amount to Seller in immediately available funds plus interest on such
additional amount accruing after the sixty (60) days after the end of such
Anniversary Period at the Prime Rate, calculated on the basis of a 365-day year,
and such payment (excluding interest) shall be part of the Earnout Amount for
such Anniversary Period.

     (d) For purposes hereof, "Plant Profits" for any given Anniversary Period
shall mean the consolidated net income solely with respect to the Company's
operations at Kendallville, Indiana, Bluffton, Ohio and Upper Sandusky, Ohio
facilities (and excluding the Company's Rochester Hills, Michigan facility) (the
"Southern Plants") for such Anniversary Period, as determined in accordance

                                      -3-
<PAGE>
 
with GAAP plus, to the extent such net income has been reduced thereby, (i) the
amount of federal, state and local income taxes and other taxes imposed upon net
income or receipts of the Southern Plants plus (ii) the amount of amortization
in respect of intangible assets (including launch costs) for such Anniversary
Period plus (iii) the amount of interest expense for indebtedness for borrowed
money (including capitalized leases) for such Anniversary Period plus (iv)
management fees paid to Buyer, if any; provided however that such Plant Profits
will be adjusted pursuant to Schedule 1.4(d) attached hereto (the "Plant Profits
Adjustments Schedule").

     (e) At the request of Seller, representatives of Buyer shall meet with
representatives of Seller on a quarterly basis (the "Oversight Committee") to
review and discuss the Company's current and future operations including,
without limitation, current and future staffing levels and repair and
maintenance matters as they relate to Plant Profits. The Buyer will, promptly
upon completion thereof, provide Seller copies of the Company's unaudited
balance sheet and related statement of operations on a quarterly basis during
each Anniversary Period.

     1.5 CLOSING TRANSACTIONS.

     (a) Closing. The closing of Buyer's purchase of the Company Stock
contemplated by this Agreement (the "Closing") will take place at the offices of

Section 1.5(c)(v) above.

pending or to the knowledge of Seller threatened, relating to the ownership,
lease, use, occupancy or operation by any person of the Real Property or the
Leased Real Property. The current use of the Real Property (and, to Seller's

will have or result in, a significant adverse effect on the operation of the
Company.

"Improvements Schedule"), all components of all buildings, structures and other
improvements included within the Real Property and the Leased Real Property (the

facts or conditions affecting any of the Improvements which would, individually
or in the aggregate, interfere in any significant respect with the use,
occupancy or operation thereof as currently used, occupied or operated or
currently intended to be used, occupied or operated. Except as set forth on the
Improvements Schedule, all water, gas, electrical, steam, compressed air,
telecommunication, sanitary and storm sewage lines and systems and other similar
systems serving the Real Property and the Leased Real Property are installed and
operating and are sufficient to enable the Real Property and the Leased Real
Property to continue to be used and operated in the manner currently being used
and operated. Except as disclosed on the Surveys, each Improvement has direct
access to a public street adjoining the Real Property and the Leased Real
Property on which such Improvement is situated over the driveways and accessways
currently being used in connection with the use and operation of such
Improvement and no existing accessway crosses or encroaches upon any property or
property interest not owned by the Company. To the knowledge of Seller, no
Improvement or portion thereof is dependent for its access, operation or utility
on any land, building or other improvement not included in the Real Property and
the Leased Real Property. Except as disclosed on the Surveys, there are no
survey defects or encroachments from or onto any of the Real Property and the

adversely determined, would entitle the Indemnified Party to an indemnity
payment pursuant to this Section 5.2, the Indemnified Party shall promptly

detail the basis of such claim and the facts pertaining thereto and the

Indemnifying Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without prior written
consent of the Indemnified Party (not to be withheld unreasonably) unless the
judgment or proposed

                                      -26-

settlement involves only the payment of money damages solely by the Indemnifying
Party and does not impose an injunction or any other equitable relief upon the
Indemnified Party.

     (f) If the Indemnifying Party has failed to assume the defense of any Third
Party Claim, the Indemnified Party may defend against such Third Party Claim in
any manner it may reasonably deem appropriate; provided, however, if the
Indemnifying Party is prevented from electing control of any defense as a result
of the Indemnified Party's refusal to give written consent thereto (i) the
Indemnified Party will not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim involving the payment of
money damages by the Indemnifying Party without the prior written consent of the
Indemnifying Party (not to be withheld unreasonably), (ii) the fees and expenses
of any counsel employed by the Indemnified Party shall be split evenly between
the Indemnified Party and the Indemnifying Party and (iii) the Indemnifying
Party shall have the right to employ counsel separate from counsel employed by
the Indemnifying Party in any such action and to participate in the defense
thereof. If the Indemnifying Party elects to assume and control the defense, the
Indemnified Party shall have the right to employ counsel separate from counsel
employed by the Indemnifying Party in any such action and to participate in the
defense thereof, but the fees and expenses of such counsel employed by the
Indemnified Party shall be at the expense of the Indemnified Party unless the
employment thereof has been specifically authorized by the Indemnifying Party in
writing.

     (g) Effective upon the Closing, except as otherwise set forth in the Oxford
Agreement, Seller hereby irrevocably waives, releases and discharges forever the
Company from any and all liabilities and obligations to Seller, its affiliates,
officers and directors of any kind or nature whatsoever in existence as of the
Closing Date, whether in its or his capacity as Seller hereunder, as a
stockholder, officer or director of the Company or otherwise, including, without
limitation, in respect of rights of contribution or indemnification, in each
case whether absolute or contingent, liquidated or unliquidated, and whether
arising hereunder or under any other agreement or understanding or otherwise at
law or equity, and Seller hereby covenants and agrees that it will indemnify and
hold harmless the Company and the Buyer Group from and against all such
liabilities or obligations.

     (h) (i) After the Closing, and with respect to environmental matters for
which Seller is obligated to indemnify Buyer under Section 5.2(a)(iv) and under
Section 5.2(a)(i) (which would entitle the Indemnified Party to an indemnity
payment pursuant to this Section 5.2), Seller shall, upon acknowledging such
obligation in writing, have the option to assume principal control of any such
environmental matter and to (i) obtain any tests, reports, and surveys necessary
to define and delineate the extent of any contamination or noncompliance, (ii)
contact governmental authorities, make any reports to such authorities, submit
any remediation or compliance plans to such authorities, negotiate with such
authorities, and otherwise deal with such authorities, (iii) prepare the work
plan for any remediation or correction of noncompliance, and (iv) conduct or
direct any such remediation or correction of noncompliance. If Seller elects to
assume principal control of such environmental matter, Seller shall manage such
environmental matter in good faith and any activities conducted in connection
therewith shall be undertaken promptly and concluded expeditiously, using all
reasonable efforts, subject to the schedules and approvals required by the
applicable governmental or regulatory

                                      -27-

<PAGE>
 
authorities. To carry out its obligations under this Agreement, Seller shall,
provided Seller provides Buyer reasonable advance notice, have reasonable access
to the affected premises and the right to perform any such environmental
remediation, investigation, assessment, sampling, monitoring, treatment,
removal, cleanup or other action required by governmental authorities to comply
with Environmental and Safety Requirements ("Remediation") by means approved by
applicable governmental or regulatory authorities and considered reasonable and
customary in the environmental engineering profession (including the right to
construct and maintain wells, dikes, "caps" or covers, barriers, pump and treat
systems, soil vapor extraction systems, other testing and treatment equipment
and systems, related buildings and structures, and supporting utility services
on such premises, the right to perform excavations and exhumations of soils and
subsurface materials and withdrawals and reinjections of groundwater on such
premises); provided, however, that Seller will not unreasonably interfere with
the normal business operations of the Company and provided, further, that Seller
shall not compound or aggravate any environmental matter for which it is not
indemnifying Buyer pursuant to Section 5.2(a) above. Seller agrees to promptly
dispose of all soil, groundwater, waste, decontamination water, cuttings,
samples, or other material generated as a result of the Remediation, and agrees
to restore the affected premises as nearly as is feasible to its prior condition
as soon as practicable. Any such Remediation shall be deemed sufficient to
satisfy corresponding obligations under this Agreement so long as the result
meets or exceeds applicable standards (including any standards resulting from
any site-specific risk assessments) under all applicable Environmental and
Safety Requirements in effect at the time of completion of the Remediation based
on the use of the property as of the Closing Date. Buyer will cooperate with
Seller (including by making relevant personnel and non-privileged records
available to Seller at all reasonable times without charge for any immaterial
internal costs) in connection with the Remediation.

          (ii)  Buyer will cooperate with Seller in connection with Seller's
     efforts to seek reimbursement under applicable governmental underground
     storage tank or other reimbursement programs relating to Environmental and
     Safety Requirements and under applicable insurance policies of the Company
     which are in effect for periods prior to the Closing relating to
     remediation or other liabilities for which Seller may be responsible that
     are related to or arise out of Environmental and Safety Requirements.

          (iii) Seller shall keep the Buyer regularly informed regarding such
     Remediation and shall provide the Buyer with copies of all monitoring,
     sampling and other data relating to the Remediation. Seller shall give
     Buyer the opportunity to review and comment in advance upon any material
     submissions to governmental or regulatory authorities with respect to the
     Remediation and Seller shall reasonably address and incorporate Buyer's
     comments that are within the scope of Seller's obligation hereunder. Buyer
     shall have the right to attend and participate in material meetings with
     governmental or regulatory authorities with respect to the Remediation.

          (iv)  To better delineate the respective obligations of Seller and
     Buyer with respect to environmental matters involving the Company, Buyer
     will use commercially reasonable best efforts to cause the Company to
     conduct its operations after the Closing Date in material

                                      -28-
<PAGE>
 
     compliance with Environmental and Safety Requirements so as not to compound
     or aggravate any environmental condition or noncompliance for which Seller
     is responsible under this Agreement.

          (v)   Buyer will maintain in confidence information concerning any
     environmental matter for which Seller is obligated to indemnify Buyer under
     Section 5.2(a). Notwithstanding the foregoing, Buyer may disclose such
     information (A) in confidence to any Person with whom Buyer proposes to
     enter into contract for any commercial purpose, including financing
     entities; (B) as required by Environmental and Safety Requirements or any
     other applicable law, including, without limitation, securities laws; (C)
     in order to attain compliance with Environmental and Safety Requirements;
     and (D) that is otherwise publicly available. Buyer shall not take action
     designed to initiate or encourage a claim by a third party, including any
     governmental agency, concerning an environmental matter for which Seller is
     obligated to indemnify Buyer under Section 5.2(a). Notwithstanding the
     foregoing, Buyer may take any action required by Environmental and Safety
     Requirements, in order to attain compliance with Environmental and Safety
     Requirements, or take such proactive action that is reasonable and prudent
     under the circumstance in order to prevent or mitigate a risk to human
     health or the environment. If Buyer intends to disclose information or take
     action concerning an environmental matter for which Seller is obligated to
     indemnify Buyer under Section 5.2(a), Buyer will notify Seller of such
     proposed disclosure or action.

     (i)  The indemnification provisions in this Agreement shall be the
exclusive remedy (other than equitable remedies and remedies for intentional
misrepresentation) for any breach of the representations, warranties and
covenants contained in this Agreement. Without limiting the generality of the
foregoing, Buyer explicitly waives to the extent permitted by applicable law any
rights and remedies under the common law, and any statutory rights and remedies,
that it otherwise might have against Seller after the Closing with respect to
the Company, excluding any remedy that Buyer may have for intentional
misrepresentation, in which case the foregoing indemnification provisions are in
addition to, and not in derogation of, any statutory or common law remedy the
Buyer may have for such intentional misrepresentation.

     (j)  Nothing set forth in this Section 5.2 shall be construed to require
the Company or the Buyer Group to modify the terms, scope or size of their
insurance coverage as in effect on the Closing Date.

     (k)  Subject to the terms and conditions set forth in this Section 5.2, in
the event of a breach of any representation, warranty, covenant or agreement
contained in this Agreement, the non-breaching party may, at its option, setoff
all or any portion of a Loss for which the parties do not dispute (or any other
Loss after a Final Determination is made with respect thereto pursuant to
Section 5.3(e) below) which such party suffers, sustains or becomes subject to
as a result of such breach against any amounts due or to become due to the
breaching party pursuant to this Agreement or the Note.

     5.3  ARBITRATION PROCEDURES.

     (a)  The parties hereto agree that the arbitration procedure set forth
below shall be the sole and exclusive method for resolving and remedying claims
for money damages arising out of this Agreement (the "Disputes"), except as
otherwise provided by Sections 1.3 and 1.4 above. Nothing in this Section 5.3
shall prohibit a party hereto from instituting litigation to enforce any Final
Determination (as defined in subsection (e) below) or availing itself of the
other remedies set forth in Sections 6.6, 6.8(b) and 6.11(f) below. The parties
hereto hereby agree and acknowledge that, except as otherwise provided in this
Section 5.3 or in the Commercial Arbitration Rules of the American Arbitration
Association, as in effect from time to time, the arbitration procedures and any
Final Determination hereunder shall be governed by, and shall be enforced
pursuant to the Uniform Arbitration Act of the State of Michigan.

     (b)  In the event that any party hereto asserts that there exists a
Dispute, such party shall deliver a written notice to each other party involved
therein specifying the nature of the asserted Dispute and requesting a meeting
to attempt to resolve the same. If no such resolution is reached within 20
business days after such delivery of such notice, the party delivering such
notice of Dispute (the "Disputing Person") may, within 45 business days after
delivery of such notice, commence arbitration hereunder by delivering to each
other party involved therein a notice of arbitration (a "Notice of
Arbitration"). Such Notice of Arbitration shall specify the matters as to which
arbitration is sought, the nature of any Dispute, the claims of each party to
the arbitration and shall specify the amount and nature of any damages, if any,
sought to be recovered as a result of any alleged claim, and any other matters
required by the Commercial Arbitration Rules of the American Arbitration
Association, as in effect from time to time, to be included therein, if any.

     (c)  Buyer and Seller shall each select one independent arbitrator expert
in the subject matter of the Dispute (the arbitrators so selected shall be
referred to herein as "Buyer's Arbitrator" and "Seller's Arbitrator,"
respectively). In the event that either party fails to select an independent
arbitrator as set forth herein within 20 days from delivery of a Notice of
Arbitration, then the matter shall be resolved by the arbitrator selected by the
other party. Seller's Arbitrator and Buyer's Arbitrator shall select a third
independent arbitrator expert in the subject matter of the dispute, and the
three arbitrators so selected shall resolve the matter according to the
procedures set forth in this Section 5.3. If Seller's Arbitrator and Buyer's
Arbitrator are unable to agree on a third arbitrator within 20 days after their
selection, Seller's Arbitrator and Buyer's Arbitrator shall each prepare a list
of three independent arbitrators. Seller's Arbitrator and Buyer's Arbitrator
shall each have the opportunity to designate as objectionable and eliminate one
arbitrator from the other arbitrator's list within seven days after submission
thereof, and the third arbitrator shall then be selected by lot from the
arbitrators remaining on the lists submitted by Seller's Arbitrator and Buyer's
Arbitrator.

     (d)  The arbitrator(s) selected pursuant to subsection (c) above will
determine the allocation of the costs and expenses of arbitration based upon the
percentage which the portion of the contested amount not awarded to each party
bears to the amount actually contested by such party. For example, if Buyer
submits a claim for $1,000, and if Seller contests only $500 of the amount
claimed by Buyer, and if the arbitrator(s) ultimately resolves the dispute by
awarding Buyer $300

                                      -30-

<PAGE>
 
of the $500 contested, then the costs and expenses of arbitration will be
allocated 60% (i.e. 300 / 500) to Seller and 40% (i.e. 200 / 500) to Buyer.

     (e)  The arbitration shall be conducted under the Commercial Arbitration
Rules of the American Arbitration Association as in effect from time to time,
except as modified by the agreement of all parties. The arbitrator(s) shall so
conduct the arbitration that a final result, determination, finding, judgment
and/or award (the "Final Determination") is made or rendered as soon as
practicable, but in no event later than the later of 90 business days after the
delivery of the Notice of Arbitration and 10 days following completion of the
arbitration. The Final Determination must be agreed upon and signed by the sole
arbitrator or by at least two of the three arbitrators (as the case may be). The
Final Determination shall be final and binding on all parties and there shall be
no appeal from or reexamination of the Final Determination, except for fraud,
perjury, evident partiality or misconduct by an arbitrator prejudicing the
rights of any party and except to correct manifest clerical errors.

     (f)  Buyer and Seller may enforce any Final Determination in any state or
federal court having jurisdiction over the dispute. For the purpose of any
action or proceeding instituted with respect to any Final Determination, each
party hereto hereby irrevocably submits to the jurisdiction of such courts,
irrevocably consents to the service of process by registered mail or personal
service and hereby irrevocably waives, to the fullest extent permitted by law,
any objection which it may have or hereafter have as to personal jurisdiction,
the laying of the venue of any such action or proceeding brought in any such
court and any claim that any such action or proceeding brought in such court has
been brought in any inconvenient forum.

     (g)  If any party shall fail to pay the amount of any damages, if any,
assessed against it within 10 days of the delivery to such party of such Final
Determination, the unpaid amount shall bear interest from the date of such
delivery at the lesser of (i) the prime rate, as declared by Citibank, N.A. from
time to time (which rate shall be adjusted on the effective date of each change
in such rate) (the "Prime Rate") plus 300 basis points and (ii) the maximum rate
permitted by applicable usury laws. Interest on any such unpaid amount shall be
compounded semiannually, computed on the basis of a 365-day year and shall be
payable on demand. In addition, such party shall promptly reimburse the other
party for all reasonable costs or expenses of any nature or kind whatsoever
(including but not limited to all attorneys' fees) incurred in seeking to
collect such damages or to enforce any Final Determination.

                                  ARTICLE VI

                             ADDITIONAL AGREEMENTS
                             ---------------------

     6.1  TAX MATTERS. The following provisions shall govern the allocation of
responsibility as between Buyer and Seller for certain tax matters following the
Closing Date:

                                      -31-

<PAGE>
 
     (a)  Tax Periods Ending on or Before the Closing Date. Buyer shall prepare
or cause to be prepared and file or cause to be filed all Tax Returns for the
Company for all periods ending on or prior to the Closing Date which are filed
after the Closing Date (other than (i) income Tax Returns with respect to
periods for which the consolidated, unitary and combined income Tax Returns of
Seller will include the operations of the Company and (ii) Tax Returns filed
under the Michigan Single Business Tax, each of such Tax Returns the Seller will
prepare and pay such Taxes). Seller shall pay to Buyer within fifteen (15) days
of the date on which any such Taxes are paid by Buyer with respect to such
period an amount equal to such Taxes to the extent such Taxes are not accrued on
the Closing Statement of Working Capital.

     (b)  Tax Periods Beginning Before and Ending After the Closing Date. Buyer
shall prepare or cause to be prepared and file or cause to be filed any Tax
Returns of the Company for Tax periods which begin before the Closing Date and
end after the Closing Date. Seller shall pay to Buyer within fifteen (15) days
of the date on which Taxes are paid with respect to such periods an amount equal
to the portion of such Taxes which relates to the portion of such Taxable period
ending on the Closing Date to the extent such Taxes are not accrued on the
Closing Statement of Working Capital. For purposes of this Section, in the case
of any Taxes that are imposed on a periodic basis and are payable for a Taxable
period that includes (but does not end on) the Closing Date, the portion of such
Taxes which relates to the portion of such Taxable period ending on the Closing
Date shall (x) in the case of any Taxes other than Taxes based upon or related
to income, be deemed to be the amount of such Tax for the entire Taxable period
multiplied by a fraction the numerator of which is the number of days in the
Taxable period ending on the Closing Date and the denominator of which is the
number of days in the entire Taxable period, and (y) in the case of any Tax
based upon or related to income be deemed equal to the amount which would be
payable if the relevant Taxable period ended on the Closing Date. Any credits
relating to a Taxable period that begins before and ends after the Closing Date
shall be taken into account as though the relevant Taxable period ended on the
Closing Date. All determinations necessary to give effect to the foregoing
allocations shall be made in a manner consistent with prior practice of such
Company.

     (c)  Cooperation on Tax Matters.

          (i)   Buyer, the Company and Seller shall cooperate fully, as and to
     the extent reasonably requested by the other party, in connection with the
     filing of Tax Returns pursuant to this Section and any audit, litigation or
     other proceeding with respect to Taxes. Such cooperation shall include (i)
     the provision of records and information necessary for completion of 1996
     Tax Returns within sixty (60) days after Closing and (ii) the retention and
     (upon the other party's request) the provision of records and information
     which are reasonably relevant to any such audit, litigation or other
     proceeding and making employees available on a mutually convenient basis to
     provide additional information and explanation of any material provided
     hereunder. The Company and Seller agree (A) to retain all books and records
     with respect to Tax matters and pertinent to the Company relating to any
     taxable period beginning before the Closing Date until the expiration of
     the statute of limitations (and, to the extent notified by Buyer or Seller,
     any extensions thereof) of the respective taxable periods, and to abide by
     all record retention agreements entered into with any taxing

                                      -32-

<PAGE>
 
     authority, and (B) to give the other party reasonable written notice prior
     to transferring , destroying or discarding any such books and records and,
     if the other party so requests, the Company or Seller, as the case may be,
     shall allow the other party to take possession of such books and records.

          (ii)  Buyer and Seller further agree, upon request, to use their best
     efforts to obtain any certificate or other document from any governmental
     authority or any other Person as may be necessary to mitigate, reduce or
     eliminate any Tax that could be imposed (including, but not limited to,
     with respect to the transactions contemplated hereby).

     (d)  Tax Sharing Agreements. All tax-sharing agreements or similar
agreements with respect to or involving the Company shall be terminated as of
the Closing Date and, after the Closing Date, the Company shall not be bound
thereby or have any liability thereunder.

     (e)  Certain Taxes. All transfer, documentary, sales, use, stamp,
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement shall be paid by Seller
when due, and Seller will, at its own expense, file all necessary Tax Returns
and other documentation with respect to all such transfer, documentary, sales,
use, stamp, registration and other Taxes and fees, and, if required by
applicable law, Buyer will, and will cause its affiliates to, join in the
execution of any such Tax Returns and other documentation.

     6.2  EMPLOYEE BENEFIT MATTERS.

     (a)  Effective the day following the Closing Date, those employees of the
Company whose employment with the Company shall continue after the Closing Date
(the "Continued Employees") shall cease to be covered under the employee benefit
plans of Seller and shall participate under the employee benefit plans, programs
and policies maintained by the Company. Seller shall remain liable for all
benefits accrued or claims incurred on or prior to the Closing Date under all
plans, programs and policies maintained by Seller, and the Company shall be
liable for all benefits accrued and claims incurred after the Closing Date under
the plans, programs and policies maintained by the Company. The Continued
Employees shall be covered under the Company's employee benefit plans without
any exclusion for pre-existing conditions and shall recognize the employees
service with Seller for purposes of vesting and eligibility under such plans.

     (b)  Seller shall remain liable for all workers' compensation claims
accrued or incurred on or prior to, or incurred as a result of any event
occurring or state of facts existing on or prior to, the Closing Date, and the
Company shall be liable for all workers' compensation claims incurred as a
result of any event occurring or state of facts existing after the Closing Date.

     (c)  As of the Closing Date, Seller shall vest each Continued Employee
under each employee benefit plan which is an employee pension benefit plan (as
defined in Section 3(2) of ERISA), and shall distribute the benefits accrued
through the Closing Date for such Continued Employees under each such plan in
accordance with the terms of said plans, assuming for such purpose that the
employees had terminated employment on the Closing Date. Seller has made or

                                      -33-

<PAGE>
 
shall make all contributions for the benefit of the Continued Employees to such
plans, excluding profit sharing to the extent such contributions are
discretionary, for the pro rata portion of the 1996 fiscal year from January 1,
1996 through the Closing Date.

     (d)  Seller shall be solely responsible for the provision of health care
continuation coverage required under COBRA for those former employees of the
Company and other persons whose entitlement to continuation coverage occurred on
or before the Closing Date. The Company shall offer continuation coverage under
its group health plans to all eligible Continued Employees after the Closing
Date.

     (e)  Buyer shall cause the Company to use reasonable efforts to continue to
employ those employees employed by the Company as of the Closing Date (except
for those employees identified on Schedule 6.2 attached hereto), at salaries and
positions that are substantially the same as in effect immediately prior to the
Closing Date, until July 30, 1996.

     (f)  Seller shall pay within 45 days following the Closing Date (i) all
stay bonuses, employee retention bonuses, success bonuses and similar
arrangements which have been granted to the Company's employees prior to the
Closing Date and (ii) the pro-rata portion (based on the number of days between
January 1, 1996 and the Closing Date) of non-discretionary annual employee
bonuses.

     (g)  Except as otherwise provided, on and after the Closing Date and
through December 31, 1996, the retirees and employees of the Company as set
forth on Schedule 6.2(g) attached hereto (the "Retiree Schedule") (the
"Retirees") may remain covered (or eligible for coverage) under Seller's
employee benefit plans described in the January 1, 1996 Actuarial Valuation of
Post Retirement Life and Health Benefit Plans report. Seller will provide the
Company, on a quarterly basis, with a detailed description of the actual costs
of such Retirees' coverage under Seller's employee benefit plans and the Company
shall reimburse Seller for such costs, without regard to any claim by the
Company or Buyer for any offset or other claim against Seller . Upon providing
written notice to Seller on or prior to December 31, 1996, the Company shall
replace such coverage with coverage under employee benefit plans sponsored by
the Company. The Company also reserves the right to modify such coverage to the
extent allowed by law; provided that the Buyer will indemnify Seller for and
against any claims arising in any way from the Company's failure to maintain the
level of benefit coverage for Retirees which is identical to the level of
benefit coverage presently provided to Retirees by Seller.

     6.3  INTERCOMPANY ACCOUNTS. Immediately prior to the Closing, the Seller
and any of its affiliates will cancel, without payment, any intercompany
accounts payable (or negative accounts receivable) owed by the Company to the
Seller or any of its affiliates.

     6.4  PRESS RELEASES AND ANNOUNCEMENTS. After the Closing Date, no press
releases related to this Agreement and the transactions contemplated herein, or
other announcements to the employees, customers or suppliers of the Company will
be issued by a party hereto without the other party's consent (which shall not
be unreasonably withheld) except for any public disclosure which

                                      -34-

<PAGE>
 
is required by law or regulation and which must be made within such a time frame
as to prevent the disclosing party from obtaining the other party's approval in
a timely fashion.

     6.5  FURTHER TRANSFERS. Seller will execute and deliver such further
instruments of conveyance and transfer and take such additional action as Buyer
may reasonably request to effect, consummate, confirm or evidence the transfer
to Buyer of the Company Stock and any other transactions contemplated hereby.

     6.6  SPECIFIC PERFORMANCE. Seller acknowledges that the Company's business
is unique and recognize and affirm that in the event of a breach of this
Agreement by Seller, money damages may be inadequate and Buyer may have no
adequate remedy at law. Accordingly, Seller agrees that Buyer shall have the
right, in addition to any other rights and remedies existing in its favor, to
enforce its rights and Seller's obligations hereunder not only by an action or
actions for damages but also by an action or actions for specific performance,
injunctive and/or other equitable relief.

     6.7  TRANSITION ASSISTANCE.

     (a)  Seller will continue to provide, for a period not to exceed 60 days
from the Closing Date, to the Company those transition services which have been
supplied by Seller to Company and are requested by the Company to be continued
solely to the extent necessary to permit an orderly transition to the Buyer's
operations. The Company shall pay to Seller the out-of-pocket expenses
associated with any third-party contractors required in connection with such
services which are pre-approved in writing by the Company.

     (b)  The Company shall indemnify and hold harmless Seller from and against
all claims, liabilities and obligations (collectively "Claims") which have
resulted from the performance of Services by Seller hereunder; provided,
however, that the Company shall not be required to indemnify or hold harmless
Seller to the extent the Claims are caused by the gross negligence or willful
misconduct of Seller.

     (c)  Seller will not take any action which is designed or intended to have,
or which would be reasonably anticipated to have, the effect of discouraging
customers, suppliers, lessors, licensors and other business associates from
maintaining in all material respects the same business relationships with the
Company after the date of this Agreement as were maintained with the Company
prior to the date of this Agreement.

     (d)  The Company will continue to provide to Seller those services set
forth on Schedule 6.7(d) attached hereto (the "Company Services Schedule") for
the period set forth in the Company Services Schedule. The costs associated with
such services shall be paid as set forth in the Company Services Schedule.
Seller shall indemnify and hold harmless the Company and Buyer from and against
all Claims which have resulted from the performance of services by the Company
hereunder; provided, however, that Seller shall not be required to indemnify or
hold harmless the Company or Buyer to the extent the Claims are caused by the
gross negligence or willful misconduct of the Company or Buyer.

                                      -35-

     6.8  INVESTIGATION; CONFIDENTIALITY.

     (a)  Seller will maintain the confidentiality of, and will not use for any
purpose, all proprietary and other non-public information regarding the Company
(including, without limitation, any of same included in the Proprietary Rights),
except as necessary to file tax returns and other reports to governmental
agencies. In the event that Seller is requested or required (by oral question or
request for information or documents in any legal proceeding, interrogatory,
subpoena, civil investigative demand, or similar process) to disclose any such
information, Seller will notify Buyer promptly of the request or requirement so
that Buyer may seek an appropriate protective order or waive compliance with the
provisions of this Section 6.8. If, in the absence of a protective order or the
receipt of a waiver hereunder, Seller is, on the advice of counsel, compelled to
disclose any information to any tribunal or else stand liable for contempt,
Seller may disclose the information to the tribunal; provided, however, that
Seller shall use its best efforts to obtain, at the request and expense of
Buyer, an order or other assurance that confidential treatment will be accorded
to such portion of the information required to be disclosed as Buyer shall
designate. This Section 6.8 shall survive any expiration or termination of this
Agreement.

     (b)  The parties hereto acknowledge and agree that in the event of a breach
by any party of any of the provisions of this Section 6.8, monetary damages will
not constitute a sufficient remedy. Consequently, in the event of any such
breach, any non-breaching party and/or their respective successors or assigns
may, in addition to other rights and remedies existing in their favor, apply to
any court of law or equity of competent jurisdiction for specific performance
and/or injunctive or other relief in order to enforce or prevent any violations
of the provisions hereof, in each case without the requirement of posting a bond
or proving actual damages.

     6.9  EXPENSES. Except as otherwise provided herein, Buyer and Seller will
pay all of their own fees, costs and expenses (including, without limitation,
fees, costs and expenses of legal counsel, investment bankers, brokers or other
representatives and consultants and appraisal fees, costs and expenses) incurred
in connection with the negotiation of this Agreement, the performance of its

transactions contemplated hereby.

     6.11 NON-COMPETITION, NON-SOLICITATION AND CONFIDENTIALITY. In
consideration of Buyer's agreement to enter into this Agreement, and as a
condition thereto, Seller covenants and agrees as follows:

     (a)  The Company manufacturers certain automotive products primarily using
stamping processes and which include chassis and suspension components, sub-
assemblies, and modules (which, whether or not being manufactured as of the date
hereof, are referred to herein as "Stampings"), including control arms, control
links, and other devices to control kinematics.

     (b)  Seller agrees that for a period of three years from and after the
Closing Date, Seller will not engage directly or indirectly in the manufacture,
solicitation or formulation of proposal, design (with the intent to manufacture
such Stamping) or sale of Stampings anywhere in North America; provided,
however, that notwithstanding the foregoing, nothing contained in this Agreement
shall (i) limit or affect businesses currently owned by Seller which may
manufacture or sell Stampings, (ii) limit or restrict Seller from engaging in
the manufacturing or sale of Stampings in conjunction with forging, hydroforming
or tubular products operations, (iii) limit or restrict Seller from engaging in
the manufacturing or sale of Stampings sold in the automotive aftermarket, (iv)
limit or restrict Seller from engaging in the manufacturing or sale of Stampings
as prototype parts for design contracts for which the intent is to provide
design support services to independent third parties and not to ultimately
manufacture such part or (v) prevent Seller from acquiring an entity which does
manufacture or sell Stampings so long as the competing business comprises ten
percent or less of the sales of the acquired entity.

     (c)  Seller further agrees that for a period of five years from and after
the Closing Date it will not directly or indirectly engage in the solicitation,
manufacture or sale of any control arms or control links, whether produced by
stamping, forging, hydroforming, casting or otherwise, on any of the following
platforms: the Ford DN-101, UN-105, CDW-27, CT-120, VX-133, PN-96, PHN-131, and
UN-93 and the Chrysler T-300; provided that nothing set forth herein shall
prohibit Seller from continuing to sell or manufacture control links on the
preceding platforms to the extent the Seller is engaged in such sale or
manufacturing on the Closing Date.

     (d)  Seller agrees that, for a period of two years from the Closing Date,
Seller will not, and will use its best efforts to not permit Seller's affiliates
to, directly or indirectly contact or solicit for the purpose of offering
employment to or hiring (whether as an employee, consultant, agent, independent
contractor or otherwise) or actually hire any management or other key employee
employed by the Company on the Closing Date, without the prior written consent
of the Company.

     (e)  If the final judgment of a court of competent jurisdiction declares
that any term or provision of Section 6.12 is invalid or unenforceable, the
parties hereto agree that the court making the determination of invalidity or
unenforceability shall have the power to reduce the scope, duration, or area of
the term or provision, to delete specific words or phrases, or to replace any
invalid or

                                      -37-
<PAGE>
 
unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision, and this Agreement shall be enforceable as so
modified after the expiration of the time within which the judgment may be
appealed.

     (f)  Seller acknowledges and agrees that in the event of a breach by Seller
of any of the provisions of this Section 6.12, monetary damages will not
constitute a sufficient remedy. Consequently, in the event of any such breach,
the Company, Buyer and/or their respective successors or assigns may, in
addition to other rights and remedies existing in their favor, after written
notice to Seller, apply to any court of law or equity of competent jurisdiction
for specific performance and/or injunctive or other relief in order to enforce
or prevent any violations of the provisions hereof, in each case without the
requirement of posting a bond or proving actual damages.

consulting firm retained by Buyer. The cost of such investigations shall be
borne solely by Buyer.

facility, Buyer shall provide Seller with a written notice of the discovery of
such Contamination ("Remediation Notice"). The Remediation Notice shall identify
the environmental consulting firm that conducted the environmental

submit a completed application to the Indiana Department of Environmental
Management ("IDEM") to enter into the Program. For purposes of the Program, the
application shall identify Seller as the applicant and Buyer as the
owner/operator. The application shall contain all analytical data that served as
the basis for the Remediation Notice together with other relevant data developed
by Seller in its investigation. Seller shall be responsible for any fees or
expenses associated with submitting the application. Upon acceptance into the
Program, Seller shall, at its sole cost and expense, expeditiously take such
actions as required by IDEM to obtain the certificate of completion and covenant
not to sue available from IDEM pursuant to such Program. Upon receipt of such
certificate of completion and covenant not to sue, any and all obligations of
Seller with respect to remediation of the Contamination shall be deemed to be
fully satisfied.

     (e)  Upon reasonable advance notice by Seller, Buyer shall grant Seller
reasonable access to, and entry upon, the Kendallville facility for the purpose
of investigating or remediating the Contamination and performing its obligations
otherwise agreed to herein. In investigating, remediating, or otherwise
responding to the Contamination, Seller shall not unreasonably interfere with
Buyer's operations at the Kendallville facility.

     (f)  Seller shall, at its expense, promptly restore as nearly as feasible
to its prior condition any property that is damaged as a result of any of any
activities relating to its investigation, remediation, or response to the
Contamination. Seller shall, at its expense and in its own name, promptly and
properly dispose of any drill cuttings, decontamination water, soil,
groundwater, waste, samples, or other material generated by the investigation,
remediation, or response to the Contamination. Buyer agrees to grant to Seller
title to any and all such materials in order to permit Seller to take the
actions described in the preceding sentence.

     (g)  Seller shall keep Buyer reasonably apprised of material facts and
events with respect to Seller's remediation of the Contamination. In particular,
Seller shall: (i) provide Buyer with reasonable advance notice regarding any
meetings between Seller and IDEM or any other governmental agency regarding this
matter and allow Buyer to attend, at Buyer's expense, such meetings; (ii)
provide Buyer with copies of letters and notices it receives from IDEM or any
other governmental agency regarding this matter; and (iii) provide Buyer with
drafts of any material submittals to IDEM or any other governmental agency
regarding this matter, including reports, analytical data, letters, or other
documents, allow Buyer to comment on such draft submittals, reasonably address
such comments, and provide Buyer with copies of the final submittals.

     (h)  Buyer and Seller agree to reasonably cooperate with one another
regarding the investigation and remediation of the Contamination and agree that
any activity conducted by either party in connection therewith shall be
undertaken promptly, conducted in compliance with law, and concluded
expeditiously.

"Hazardous Substance," as defined in Ind. Code 13-7-8.9-2, or "Petroleum," as
defined in Ind. Code 13-7-8.9-3,

direction or the consent of the Majority Benefited Parties.  The Collateral
Agent agrees to administer the Security Documents and the Collateral and to make
such demands and give such notices under the Security 

                                      -9-
<PAGE>
 
Documents as the Majority Benefited Parties may request, and to take such action
to enforce the Security Documents and to realize upon, collect and dispose of
the Collateral or any portion thereof as may be directed by the Majority
Benefited Parties.

       (d) Notwithstanding anything herein to the contrary, the Collateral Agent
shall not be required to take any action that is in the Opinion of Counsel
(which opinion shall not, for purposes of this (S)3(D), be subject to the
approval of the Majority Benefited Parties) contrary to law or to the terms of
this Agreement or the Security Documents, or that would in such Opinion of
Counsel subject it or any of its officers, employees, agents or directors to
liability.  The Collateral Agent shall advise the Benefited Parties in writing 
within 3 business days of any decision not to act pursuant to the immediately
preceding sentence and include therewith a copy of such Opinion of Counsel.

       (e) Each Party agrees that the Collateral Agent shall act as the Majority
Benefited Parties may request (regardless of whether any individual Party or
Benefited Party agrees, disagrees or abstains with respect to such request),
that the Collateral Agent shall have no liability for acting in accordance with
such request (provided such action does not conflict with the express terms of
this Agreement or the Security Documents) and that no Directing Party or Non-
Directing Party shall have any liability to any Non-Directing Party or Directing
Party, respectively, for any such request.  The Collateral Agent shall give
prompt notice to the Non-Directing Parties of action taken pursuant to the
instructions of the Majority Benefited Parties to enforce any Security Document;
provided, however, that the failure to give any such notice shall not impair the
right of the Collateral Agent to take any such action or the validity or
enforceability under this Agreement of the action so taken.  Notwithstanding
anything herein to the contrary, the Majority Benefited Parties shall agree to
release the Collateral from the security interests granted for the benefit of
any Non-Directing Party only if the Collateral Agent is concurrently releasing
the security interest granted with respect to such Collateral for all Benefited
Parties having a security interest in such Collateral.

       (f) Each Party agrees that the only right of a Non-Directing Party under
the Security Documents is for Benefited Obligations held by such Non-Directing
Party to be secured by the Collateral for the period and to the extent provided
therein and in this Agreement and to receive a share of the proceeds of
enforcement of the Security Documents, if any, to the extent and at the time
provided in the respective Security Documents and in this Agreement.

       (g) The Collateral Agent may at any time request directions from the
Majority Benefited Parties as to any course of action or other matter relating
hereto or relating to any Security Document.  Except as otherwise provided in
this Agreement or the Security Documents, directions given by the Majority
Benefited Parties to the Collateral Agent hereunder shall be binding on all
Benefited Parties, including all Non-Directing Parties, for all purposes.

       (h) Nothing contained in this Agreement shall affect the rights of any
Party to give the Company or any other Grantor notice of any default, accelerate
or make demand for payment of their respective Benefited Obligations under the
Financing Agreements.  If a Party (upon authorization or with the consent of the
Majority Benefited Parties) instructs the Collateral Agent to take any action,
commence any proceedings or otherwise proceed against the Collateral or enforce
any Security Document, and such action or proceedings are or may be defective
without 

                                      -10-
<PAGE>
 
the joinder of other Parties as parties, then all other Parties shall
join in such actions or proceedings.  Each Party agrees not to take any action
to enforce any term or provision of the Security Documents or to enforce any of
its rights in respect of the Collateral except through the Collateral Agent in
accordance with this Agreement.

       (i) If the Collateral Agent has been notified in writing that an Event of
Default has occurred, the Collateral Agent shall notify the Benefited Parties
and may notify the Company of such determination.  Any Benefited Party which has
actual knowledge of an Event of Default, or facts which indicate that an Event
of Default has occurred, shall deliver to the Collateral Agent a written
statement describing such Event of Default or facts.  Failure to do so, however,
does not constitute a waiver of such Event of Default by the Benefited Parties.
Upon receipt of a notice from a Benefited Party of the occurrence of an Event of
Default, the Collateral Agent shall promptly (and in any event no later than
three business days after receipt of such notice in the manner provided in
(S)11(A) hereof) give notice of such Event of Default to all Benefited Parties.

       (j) Unless an Event of Default has occurred and is continuing, the
Collateral Agent may, without the approval of the Benefited Parties as required
herein, release any Collateral under the Security Documents which is permitted
to be sold or disposed of by the Company or any Grantor pursuant to the Security
Documents, Credit Agreement and the Note Agreements and execute and deliver such
releases as may be necessary to terminate of record the Benefited Parties'
security interest in such Collateral.  In determining whether any such release
is permitted, the Collateral Agent may rely upon instructions from the Majority
Benefited Parties.

       (k) At any time when an Event of Default shall have occurred and be
continuing, the Company will not, directly or indirectly, pay or permit to be
paid to any Benefited Party, and the Benefited Parties will not accept, any
remuneration, whether by way of supplemental or additional interest, fees (other
than fees and expenses of counsels, other professionals, Collateral Agent and
others in connection with curing or waiving the Event of Default or amending any
Financing Agreements in connection therewith) or otherwise, as consideration for
or as inducement to the entering into of any amendment, supplement, waiver or
consent with respect to any Financing Agreements or any Security Document unless
such remuneration is concurrently therewith paid, on the same terms, ratably to
all Benefited Parties.

       (l) At no time in the future will any security interest, mortgage or
other lien be created by the Company or any of its Subsidiaries or Affiliates in
favor of, or guaranties by the Company or any of its Subsidiaries or Affiliates
be granted for the benefit of, any holder of the Benefited Obligations, unless
(x) in the case of the creation of any security interest, mortgage or other
lien, all other Benefited Obligations are secured equally and ratably with the
Benefited Obligations secured thereby on the same basis as is provided in the
Security Documents and this Agreement or (y) in the case of the giving of any
such guaranty, all other Benefited Obligations shall have the benefits of
substantially similar guaranties given by the same guarantor or guarantors.  In
the event any such security interest, mortgage, lien or guaranty is given in
violation of the foregoing, the Proceeds received by the Benefited Party in
whose favor such security interest, mortgage, lien or guaranty has been granted
shall be held in trust by such Benefited Party for the benefit of all Benefited
Parties and applied to the Benefited Obligations in the manner provided in (S)5.

SECTION 4.  SHARING OF RECOVERIES UNDER SUBSIDIARY GUARANTIES .

       (a) Any and all amounts at any time recovered by any Benefited Party from
any Subsidiary Guarantor as a result of the enforcement by such Benefited Party
of its rights and remedies under the Bank Guaranties or the Noteholders'
Guaranties, as the case may be, following the occurrence and during the
continuance of an Event of Default of which notice has been given to the
Collateral Agent shall be shared by the Benefited Parties and allocated to the
Benefited Obligations in accordance with the provisions of (S)5 in the manner
specified in (S)4(B) below.

       (b) In the event that any Benefited Party shall obtain any payment or
reduction of any Benefited Obligation as a result of the enforcement of the Bank
Guaranties or the Noteholders' Guaranties in excess of its ratable share
obtained by all of the Benefited Parties as set forth in subsection (a) above,
such Benefited Party shall forthwith (1) notify each other Benefited Party and
the Collateral Agent of such receipt and (2) enter into a mutually acceptable
arrangement with the other Benefited Parties as shall be necessary to cause such
receiving Benefited Party to share the excess payment or reduction, net of costs
incurred in connection therewith, ratably with each of them in accordance with
subsection (a) above, provided that if all or any portion of such excess payment
or reduction is thereafter recovered from such receiving Benefited Party, the
arrangement shall be rescinded and any amounts paid to the other Benefited
Parties by the receiving Benefited Party shall be restored to the extent of such
recovery.  All arrangements pursuant to this Section 4(b) shall be coordinated
by and effected at the direction of the Collateral Agent.

SECTION 5.    APPLICATION OF PROCEEDS.

       (a) Any and all Proceeds received by the Collateral Agent in connection
with an Enforcement, and the proceeds and avails of any right or remedy under
the Subsidiary Guaranties and the Security Documents, and any Preferential
Payments required to be paid to all Benefited Parties in accordance with the
provisions of (S)6, shall be applied promptly by the Collateral Agent, as
follows:

          First:  To the payment of the reasonable costs and expenses of such
     sale, collection or other realization, including fees and expenses of
     counsel, and all reasonable expenses, liabilities and advances made or
     incurred by the Collateral Agent in connection therewith;

          Second:  To the ratable payment of the Benefited Obligations to
     Benefited Parties (other than Existing Fees and Charges, New Fees and
     Charges, Note Premium Obligations and Break Costs), calculated in
     accordance with the provisions of (S)5(B) hereof;

          Third:  To the ratable payment of Note Premium Obligations and Break
     Costs to Benefited Parties;

                                      -12-
<PAGE>
 
          Fourth:  To the ratable payment of the Existing Fees and Charges to
     Benefited Parties;

          Fifth:  To the ratable payment of the New Fees and Charges to
     Benefited Parties; and

          Sixth:  After payment in full of all Benefited Obligations, to the
     payment to or upon the order of Grantors, or to whomsoever may be lawfully
     entitled to receive the same or as a court of competent jurisdiction may
     direct, of any surplus then remaining from such Proceeds.

Until such Proceeds are so applied, the Collateral Agent shall hold such
Proceeds in its custody in accordance with its regular procedures for handling
deposited funds.

       (b) Any Proceeds received by the Collateral Agent in respect of the
Collateral, the Security Documents or the Subsidiary Guaranties (net of any
amounts applied in accordance with (S)5(A) First) shall be applied in accordance
with the priority set forth in (S)5(A) Second so that each Benefited Party shall
receive payment of its proportionate amount of all such Proceeds, as the case
may be.  Payment shall be based upon the proportion which the amount of such
Benefited Obligations of such Benefited Party bears to the total amount of all
Benefited Obligations of all such Benefited Parties.  For purposes of
determining the proportionate amounts of all Benefited Obligations sharing in
any such distribution, (i) the amount of the outstanding Credit Obligations
shall be deemed to be the principal amount of the Credit Notes, the Letter of
Credit Usage (subject to the provisions of (S)5(D)) and all accrued interest and
fees with respect thereto but excluding New Fees and Charges, (ii) the amount of
the outstanding Senior Note Obligations shall be deemed to be the principal
amount of the Senior Notes plus all accrued interest and fees with respect
thereto including, without limitation, the Note Premium Obligations but
excluding New Fees and Charges, and (iii) the amount of the outstanding Hedging
Exposure shall be deemed to be the amount of the Company's obligations then due
and payable (exclusive of expenses or similar liabilities, but including early
termination payments then due) in connection with any Hedging Transaction and
all accrued interest and fees with respect thereto.

       (c) Payments by the Collateral Agent in respect of (i) the Credit
Obligations shall be made to the Credit Agent for distribution to the Lenders in
accordance with the Credit Agreement; (ii) the Senior Note Obligations shall be
made as directed in writing by the Noteholder to whom such Senior Note
Obligations are owed; and (iii) Hedging Exposure shall be made as directed by
the Lender to which such is owed.

       (d) For the purposes of payments and distributions under this (S)5, the
full amount of Benefited Obligations on account of any outstanding Letter of
Credit shall be deemed to be then due and owing, and the face amount of any
Letter of Credit then outstanding but not drawn upon and all unreimbursed
obligations (other than amounts attributable to interest, fees and costs) due on
any Letters of Credit that have been drawn upon shall be considered principal
owing pursuant to Benefited Obligations relating to Letters of Credit and the
amount outstanding under the Letters of Credit for purposes of determining pro
rata sharing or otherwise.  Amounts 

                                      -13-
<PAGE>
 
distributable under (S)5 to Lenders on account of such Benefited Obligations
under such Letters of Credit shall be deposited in a separate interest bearing
collateral account in the name of and under the control of the Collateral Agent
and held by the Collateral Agent, first as security for such Letter of Credit
and then as security for all other Benefited Obligations and the amount so
deposited shall be applied to reimburse the Lenders for any drawings under such
Letter of Credit, and if such Letter of Credit shall expire or terminate without
being drawn upon, then such amounts shall be applied to the remaining Benefited
Obligations in the order and manner provided under this (S)5. The Company, by
its acknowledgment and acceptance of this Agreement, hereby grants to the
Collateral Agent, for the benefit of the Benefited Parties, a lien and security
interest in all such funds deposited in such separate interest bearing
collateral account, as security for the Benefited Obligations.

SECTION 6.    PREFERENTIAL PAYMENTS AND SPECIAL TRUST ACCOUNT .

       (a) The Collateral Agent shall give each Benefited Party a written notice
(a "Notice of Special Default") promptly, but no later than, three business days
after being notified in writing by a Benefited Party that a Special Event of
Default has occurred.  After the receipt of such Notice of Special Default, all
Preferential Payments other than those payments received pursuant to (S)6(B)
shall be deposited into the Special Trust Account.  Each Benefited Party agrees
that no Event of Default shall occur as a result of payments so made on a timely
basis to the Collateral Agent.

       (b) If (i) such Special Event of Default is waived by the Required
Lenders or the Required Noteholders, or both, as the case may be, and if no
other Event of Default has occurred and is continuing, (ii) such Special Event
of Default is cured by the Company or by any amendment of the Credit Agreement
or the Note Agreements, as the case may be, and if no other Event of Default has
occurred and is continuing or (iii) the Benefited Obligations have not been
accelerated and the Majority Benefited Parties have not instructed the
Collateral Agent to seek the appointment of a receiver, commence litigation
against the Company, Tower Automotive or a Subsidiary Guarantor, liquidate the
Collateral, commence a Bankruptcy Proceeding against the Company, seize
Collateral, or exercise other remedies of similar character prior to the 90th
day following such Special Event of Default, the Collateral Agent thereupon
shall return all amounts, together with their pro rata share of interest earned
thereon, held in the Special Trust Account representing payment of any Benefited
Obligations to the Benefited Party initially entitled thereto, and no payments
thereafter received by a Benefited Party shall constitute a Preferential Payment
by reason of such cured or waived Special Event of Default.  No payment returned
to a Benefited Party for which such Benefited Party has been obligated to make a
deposit into the Special Trust Account shall thereafter ever be characterized as
a Preferential Payment.  If the Special Event of Default is an Event of Default
under the terms of the Credit Agreement and the Note Agreements, the Collateral
Agent shall not return any payments to the Benefited Parties pursuant to (i)
above unless the Required Lenders and the Required Noteholders have each waived
such Special Event of Default.

       (c) Each Benefited Party agrees that upon the occurrence of a Special
Event of Default it shall (i) promptly notify the Collateral Agent of the
receipt of any Preferential Payments, (ii) hold such amounts in trust for the
benefit of the Benefited Parties during the time any such 

                                      -14-
<PAGE>
 
amounts are held by it, and (iii) deliver to the Collateral Agent such amounts
for deposit into the Special Trust Account.

       (d) If (i) an Event of Default has occurred and has not been waived or
cured within 90 days after the occurrence thereof, (ii) the Benefited
Obligations have been accelerated or (iii) the Majority Benefited Parties have
instructed the Collateral Agent to seek the appointment of a receiver, commence
litigation against the Company, Tower Automotive or a Subsidiary Guarantor,
liquidate the Collateral, commence a Bankruptcy Proceeding against the Company,
seize Collateral, or exercise other remedies of similar character, then all
funds, together with interest earned thereon, held in the Special Trust Account
and all subsequent Preferential Payments shall be applied in accordance with the
provisions of (S)5(A) above.

SECTION 7.    INFORMATION .

     If the Collateral Agent proceeds to enforce any Security Document or
Subsidiary Guaranty or to collect, sell, otherwise dispose of any Collateral or
take any other action with respect to any of such agreements or the Collateral
or any portion thereof or proposes to take any other action pursuant to or
contemplated by this Agreement, the Parties hereto agree as follows:

            (a) The Credit Agent shall (i) promptly from time to time, upon the
     written request of the Collateral Agent, notify the Collateral Agent of the
     outstanding Credit Obligations as at such date as the Collateral Agent may
     specify; and (ii) promptly from time to time thereafter notify the
     Collateral Agent of any payment received by the Credit Agent to be applied
     to satisfy Credit Obligations. The Credit Agent shall certify as to such
     amounts and the Collateral Agent shall be entitled to rely conclusively
     upon such certification.

            (b) Each Noteholder shall (i) promptly from time to time, upon the
     written request of the Collateral Agent, notify the Collateral Agent of the
     outstanding Senior Note Obligations owed to such Noteholder as at such date
     as the Collateral Agent may specify; (ii) promptly from time to time, upon
     the written request of the Collateral Agent, notify the Collateral Agent of
     the amount that would be payable as a "Make Whole Amount" under (S)6.3 of
     the Note Agreements or any successor provision thereto if such "Make Whole
     Amount" were payable as of such date as the Collateral Agent may specify
     and (iii) promptly from time to time thereafter, notify the Collateral
     Agent of any payment received thereafter by such Noteholder to be applied
     to the principal of or interest or "Make Whole Amount" on the Senior Note
     Obligations owing to such Noteholder.  Each Noteholder shall certify as to
     such amounts and the Collateral Agent shall be entitled to rely
     conclusively upon such certification.

            (c) Each Lender party to any Letter of Credit shall (i) promptly
     from time to time, upon the written request of the Collateral Agent, notify
     the Collateral Agent of the Letter of Credit Usage applicable to such
     Letter of Credit and (ii) promptly from time to time thereafter notify the
     Collateral Agent of any payment received by such Lender to be applied to
     amounts due under such Letter of Credit.  Such Lender shall certify as to
     such 

                                      -15-
<PAGE>
 
     amounts and the Collateral Agent shall be entitled to rely conclusively
     upon such certification.

            (d) Each Lender party to a Hedging Transaction shall (i) promptly
     from time to time, upon the written request of the Collateral Agent, notify
     the Collateral Agent of the notional amount under such Hedging Transaction
     and the amount payable by the Company upon early termination of such
     Hedging Transaction at the date of termination as fixed by such Interest
     Rate Protection Agreement and (ii) promptly from time to time thereafter
     notify the Collateral Agent of any payment received by such Lender to be
     applied to amounts due upon early termination of such Hedging Transaction.
     Such Lender shall certify as to such amounts and the Collateral Agent shall
     be entitled to rely conclusively upon such certification, provided that if
     an Event of Default shall have occurred and be continuing, the
     certification of any such notional amount must be demonstrated to the
     reasonable satisfaction of the Majority Benefited Parties.

SECTION 8.    ADDITIONAL PARTIES.

     Provided that it is permitted to do so by the terms of the Credit Agreement
and the Note Agreements, the Company may enter into one or more Successor Credit
Agreements or Successor Note Agreements and, pursuant thereto, incur additional
Senior Debt.  The Senior Debt outstanding under such Successor Credit Agreements
or Successor Note Agreements, as the case may be, shall be secured by the
Collateral as provided herein and in the Security Documents and shall have the
benefit of guaranties of the Subsidiary Guarantors substantially similar to the
Subsidiary Guaranties; provided that, at the time the Company enters into any
such Successor Credit Agreements or Successor Note Agreements, each Successor
Lender party to such Successor Credit Agreement, or the agent on behalf of all
such Successor Lenders to such Successor Credit Agreement, and each Successor
Noteholder party to such Successor Note Agreements, as the case may be, shall
sign an acknowledgment in the form of Exhibit A-1 or Exhibit A-2, respectively,
attached to this Agreement, by which each such Successor Lender or each such
Successor Noteholder, as the case may be, agrees to be bound by the terms of
this Agreement, and by delivering a signed acknowledgment hereof executed by the
Company, Tower Automotive, each Subsidiary Guarantor and each Grantor to the
Collateral Agent; and provided further that on the date of execution and
delivery of such Successor Credit Agreement or Successor Note Agreements, the
incurrence by the Company of $1 of additional Indebtedness would not constitute
an Event of Default under the Note Agreements.

SECTION 9.    DISCLAIMERS, INDEMNITY, ETC. 

       (a) The Collateral Agent shall have no duties or responsibilities except
those expressly set forth in this Agreement and the Security Documents.  The
Collateral Agent shall not by reason of this Agreement or the Security Documents
be a trustee for any Benefited Party or have any other fiduciary obligation to
any Benefited Party (including any obligation under the Trust Indenture Act of
1939, as amended).  The Collateral Agent shall not be responsible to any
Benefited Party for any recitals, statements, representations or warranties
contained in any Financing Agreement or in any certificate or other document
referred to or provided for in, or 

                                      -16-
<PAGE>
 
received by any of them under, any Financing Agreement, or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of any
Financing Agreement or any other document referred to or provided for therein or
any Lien under any of the Security Documents or the perfection or priority of
any such Lien or for any failure by any Grantor, any Benefited Party or any
other Person to perform any of its respective obligations under any Financing
Agreement. Without limiting the foregoing, the Collateral Agent shall not be
required to take any action under any Security Document or any Subsidiary
Guaranty, including, without limitation, any action to perfect any security
interests granted in the Collateral pursuant to the Security Documents or to
administer any Collateral unless instructed to do so by the Majority Benefited
Parties. The Collateral Agent may employ agents and attorneys in-fact and shall
not be responsible, except as to money or securities received by it or its
authorized agents, for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care. Neither the Collateral
Agent nor any of its directors, officers, employees or agents shall be liable or
responsible for any action taken or omitted to be taken by it or them hereunder
or in connection herewith, except for the gross negligence or willful misconduct
of any such Person.

       (b) The Collateral Agent shall be entitled to rely upon any
certification, notice or other communication (including any thereof by
telephone, telex, telecopy, telegram or cable) believed by it to be genuine and
correct and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of independent legal counsel,
independent accountants and other experts selected by the Collateral Agent.  As
to any matters not expressly provided for by this Agreement, the Collateral
Agent shall in all cases be fully protected in acting, or in refraining from
acting, hereunder in accordance with instructions signed by the Majority
Benefited Parties, and such instructions of the Majority Benefited Parties, and
any action taken or failure to act pursuant thereto, shall be binding on all
Parties, Directing Parties and Non-Directing Parties.

       (c) The Benefited Parties agree that they will indemnify the Collateral
Agent in its capacity as the Collateral Agent, ratably in accordance with the
amount of the Benefited Obligations held by such Benefited Parties (which in the
case of any determination of the Credit Notes prior to the termination of the
Revolving Credit Aggregate Commitment shall include the full amount of the
Revolving Credit Aggregate Commitment, whether or not advanced and outstanding, 
but in no event less than the actual amount of Credit Notes outstanding) to the
extent neither reimbursed by the Company or a Grantor under the Security
Documents nor reimbursed out of any Proceeds pursuant to clause First of (S)5(A)
hereof, for any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever that may be imposed on, incurred by or asserted against the
Collateral Agent arising out of actions taken or not taken either (i) pursuant
to the direction or consent of the Majority Benefited Parties or (ii) otherwise
pursuant to the terms of this Agreement or the Security Documents, including
reasonable fees and expenses of counsel (including the allocated cost of
internal counsel); provided, however, that no such Benefited Party shall be
liable for any such payment to the extent the obligation to make such payment
arises solely from the Collateral Agent's gross negligence or willful
misconduct. The obligations of the Benefited Parties under this (S)9(C) shall
survive the payment in full of the Benefited Obligations and the termination of
this Agreement.

                                      -17-
<PAGE>

       (d) The Collateral Agent shall not be required to take any action under
this Agreement or the Security Documents unless and until the Collateral Agent
shall be indemnified to its reasonable satisfaction by one or more of the
Benefited Parties against any and all loss, cost, expense or liability in
connection therewith.

       (e) Except for action expressly required of the Collateral Agent
hereunder, the Collateral Agent shall, notwithstanding anything to the contrary
in (S)9(C) hereof, in all cases be fully justified in failing or refusing to act
hereunder unless it shall be further indemnified to its reasonable satisfaction
by the Parties against any and all liability and expense that may be incurred by
it by reason of taking or continuing to take any such action.

       (f) The Collateral Agent may deem and treat the payee of any promissory
note or other evidence of indebtedness or obligations relating to any Benefited
Obligation as the owner thereof for all purposes hereof unless and until a
written notice of the assignment or transfer thereof, signed by such payee and
in form reasonably satisfactory to the Collateral Agent, shall have been filed
with the Collateral Agent.  Any request, authority or consent of any Person who
at the time of making such request or giving such authority or consent is the
holder of any such note or other evidence of indebtedness or obligations shall
be conclusive and binding on any subsequent holder, transferee or assignee of
such note or other evidence of indebtedness or obligations and of any note or
notes or other evidences of indebtedness or obligations issued in exchange
therefor.

       (g) Except as expressly provided herein and in the Security Documents,
the Collateral Agent shall have no duty to take any affirmative steps with
respect to the administration or collection of amounts payable in respect of the
Security Documents, the Subsidiary Guaranties or the Collateral.  The Collateral
Agent shall incur no liability (except to the extent the actions or omissions of
the Collateral Agent in connection therewith constitute gross negligence or
willful misconduct) as a result of any sale of any Collateral, whether at any
public or private sale.

       (h) (i) The Collateral Agent may resign at any time by giving at least 30
days' notice thereof to the Parties (such resignation to take effect upon the
acceptance by a successor 

                                      -18-
<PAGE>
 
Collateral Agent of any appointment as the Collateral Agent hereunder) and the
Collateral Agent may be removed as the Collateral Agent (1) at any time prior to
an Event of Default by the Benefited Parties, considered as a single class,
holding more than 51% of the sum of (y) the outstanding principal amount of the
Senior Notes, plus (z) the outstanding principal amount of the Credit Notes
(which in the case of any determination prior to the termination of the
Revolving Credit Aggregate Commitment shall include the full amount, whether or
not advanced and outstanding, of the Revolving Credit Aggregate Commitment) and
the Letter of Credit Usage, and (2) after the occurrence and during the
continuation of any Event of Default by either (y) Benefited Parties holding (or
representing) more than 51% of the outstanding principal amount under the Credit
Notes (it being understood that, if the Required Lenders agree on any
instruction to be given the Collateral Agent, the Required Lenders shall be
entitled to vote on behalf of all Lenders for purposes of this clause) or (z)
Benefited Parties holding (or representing) more than 51% of the outstanding
principal amount under the Senior Notes. In the event of any such resignation or
removal of the Collateral Agent, the Majority Benefited Parties shall thereupon
have the right to appoint a successor Collateral Agent which is not a Benefited
Party. If no successor Collateral Agent shall have been so appointed by the
Majority Benefited Parties and shall have accepted such appointment within 30
days after the notice of the intent of the Collateral Agent to resign or the
removal of the Collateral Agent, then the retiring Collateral Agent may, on
behalf of the other Parties, appoint a successor Collateral Agent. Any successor
Collateral Agent appointed pursuant to this clause shall be a commercial bank or
other financial institution organized under the laws of the United States of
America or any state thereof having (1) a combined capital and surplus of at
least $250,000,000 and (2) a rating upon its long-term senior unsecured
indebtedness of "A-2" or better by Moody's Investors Service, Inc. or "A" or
better by Standard & Poor's Corporation.

          (ii) Upon the acceptance by a successor Collateral Agent of any
appointment as the Collateral Agent hereunder, such successor Collateral Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring or removed Collateral Agent, and the
retiring or removed Collateral Agent shall thereupon be discharged from its
duties and obligations hereunder.  After any retiring or removed Collateral
Agent's resignation or removal hereunder as the Collateral Agent, the provisions
of this (S)9 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as the Collateral Agent.

       (i) In no event shall the Collateral Agent or any Party or Benefited
Party be liable or responsible for any funds or investments of funds held by the
Company or any of its Affiliates.

       (j) Comerica shall have and may exercise the same rights and powers
hereunder and is subject to the same obligations and liabilities set forth
herein for any other Benefited Party as and to the extent of its pro rata share
of the Benefited Obligations, all as if Comerica were not appointed as the
Collateral Agent pursuant hereto.  The terms "Benefited Parties", "Lenders" or
"Required Lenders" or any similar terms shall, unless the context clearly
otherwise indicates, include Comerica or any Affiliate of Comerica in its
individual capacity as a Benefited Party, Lender or one of the Required Lenders
as and to the extent of its pro rata share of the Benefited Obligation.
Comerica and its Affiliates may lend money to, and generally engage in any kind
of business with, any Grantor as if Comerica were not acting as the Collateral
Agent pursuant 

                                      -19-
<PAGE>
 
hereto and without any duty to account therefor to the Benefited Parties.
Without limiting the foregoing, each Benefited Party acknowledges that (i)
Comerica is both a Lender and the Credit Agent under the Credit Agreement and is
acting as Collateral Agent under the Security Documents, and (ii) Comerica may
continue to engage in any credit decisions with respect to the Credit Agreement
without any duty to account therefor to the Benefited Parties by reason of its
appointment as the Collateral Agent.

       (k) Each Party acknowledges that it has, independently and without
reliance upon the Collateral Agent or any other Party and based upon such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and the other Financing
Agreements to which it is a party.  Each Party also acknowledges that it will,
independently and without reliance upon the Collateral Agent or any other Party
and based upon such documents and information as it shall deem appropriate at
the time, continue to make its own credit decisions in taking or not taking
action under the Financing Agreements to which it is a party.

SECTION 10.   INVALIDATED PAYMENTS.

     If any amount distributed by the Collateral Agent to a Benefited Party in
accordance with the provisions of this Agreement is subsequently required to be
returned or repaid by the Collateral Agent or such Benefited Party to the
Company or any Affiliate thereof or their respective representatives or
successors in interest, whether by court order, settlement or otherwise (a
"Repayment Event"), the Collateral Agent shall thereafter apply Proceeds
received in a manner consistent with the terms of this Agreement such that all
Benefited Parties receive such proportion of the Proceeds as would have been
received had the original payment which gave rise to such Repayment Event not
occurred.  If a Repayment Event occurs which results in the Collateral Agent
being required to return or repay any amount distributed by it under this
Agreement, the Benefited Party to which such amount was distributed shall,
promptly upon its receipt of a notice thereof from the Collateral Agent, pay the
Collateral Agent such amount; provided, that if any Benefited Party shall fail
to promptly pay such amount to the Collateral Agent, the Collateral Agent may
deduct such amount from any amounts payable thereafter to such Benefited Party
under this Agreement.

SECTION 11.   MISCELLANEOUS.

       (a) All notices and other communications provided for herein shall be in
writing and may be sent by overnight air courier or facsimile communication and
shall be deemed to have been given when delivered by overnight air courier or
upon receipt of facsimile communication if concurrently with transmission of
such telecopy or telex, a copy thereof shall be sent by overnight courier to the
address specified for such notice or communication.  For the purposes hereof,

delivered as provided in this (S)11(A)) shall be set forth under each party's

       (b) This Agreement may be amended, modified or waived only by an
instrument or instruments in writing signed by all of the holders of Benefited
Obligations and the Collateral Agent; provided, however, that (S)8 of this
Agreement may not be amended or modified without the written consent of the
Company, Tower Automotive and the Subsidiary Guarantors.

       (c) This Agreement shall be binding upon and inure to the benefit of the
Collateral Agent, each Party and their respective successors and assigns.  In
the event that the holder of any Credit Note or Senior Note shall transfer such
Credit Note or Senior Note, it shall promptly so advise the Collateral Agent.
Each transferee of any Credit Note or Senior Note shall take such Credit Note or
Senior Note subject to the provisions of this Agreement and to any request made,
waiver or consent given or other action taken or authorized hereunder, by each
previous holder of such Credit Note or Senior Note, prior to the receipt by the
Collateral Agent of written notice of such transfer; and, except as expressly
otherwise provided in such notice, the Collateral Agent shall be entitled to
assume conclusively that the transferee named in such notice shall thereafter be
vested with all rights and powers as a Party under this Agreement.  Upon the
written request of any Party, the Collateral Agent will provide any Party with
copies of any written notices of transfer received pursuant hereto.

       (d) This Agreement shall continue to be effective among the Parties even
though a case or proceeding under any bankruptcy or insolvency law or any
proceeding in the nature of a receivership, whether or not under any insolvency
law, shall be instituted with respect to the Company, Tower Automotive, any
Subsidiary Guarantor or any other Grantor, or any portion of the property or
assets of the Company, Tower Automotive, any Subsidiary Guarantor or any other
Grantor, and all actions taken by the Parties with regard to such proceeding
shall be by the Majority Benefited Parties; provided, however, that nothing
herein shall be interpreted to preclude any Party from filing a proof of claim
with respect to its Benefited Obligations or from casting its vote, or
abstaining from voting, for or against confirmation of a plan of reorganization
in a case of bankruptcy, insolvency or similar law in its sole discretion.

       (e) Each Party hereto agrees to do such further acts and things and to
execute and deliver such additional agreements, powers and instruments as any
other Party hereto may reasonably request to carry into effect the terms,
provisions and purposes of this Agreement or to better assure and confirm unto
such other Party hereto its respective rights, powers and remedies hereunder.

       (f) This Agreement may be executed in any number of counterparts, all of
which taken together shall constitute one and the same instrument, and any of
the parties hereto may execute this Agreement by signing any such counterpart.
A telecopy of the signature of any party on any counterpart shall be effective
as the signature of the party executing such counterpart for purposes of
effectiveness of this Agreement.

       (g) This Agreement shall become effective immediately upon execution by
the Parties and shall continue in full force and effect until one year following
the date upon which all Benefited Obligations are irrevocably paid in full and
all commitments under the Credit Agreement have been terminated, it being
understood that if at any time the Lien of the Security 

                                      -21-
<PAGE>
 
Documents shall be released by the Benefited Parties, this Agreement shall
continue in full force and effect as provided above as and with respect to the
Subsidiary Guaranties.

       (h) No course of dealing on the part of the Collateral Agent or any
Benefited Party, nor any delay or failure on the part of the Collateral Agent or
any Benefited Party in exercising any right, power or privilege hereunder shall
operate as a waiver of such right, power or privilege or otherwise prejudice the
Collateral Agent's or such Benefited Party's rights and remedies hereunder; nor
shall any single or partial exercise thereof preclude any further exercise
thereof or the exercise of any other right, power or privilege.  No right or
remedy conferred upon or reserved to the Collateral Agent or any Benefited Party
under this Agreement or the Security Documents, is intended to be exclusive of
any other right or remedy, and every right and remedy shall be cumulative and in
addition to every other right or remedy granted hereunder or thereunder or now
or hereafter existing under any applicable law.  Every right and remedy granted
by this Agreement, the Security Documents or by applicable law to the Collateral
Agent or any Benefited Party may be exercised from time to time and as often as
may be deemed expedient by the Collateral Agent or any Benefited Party and,
unless contrary to the express provisions of this Agreement or the Security
Documents irrespective of the occurrence or continuance of any Event of Default.

       (i) All terms, covenants, agreements, representations and warranties of
the Company made herein or in any certificate or other document delivered
pursuant hereto shall be deemed to be material and to have been relied upon by
the Benefited Parties, notwithstanding any investigation heretofore or hereafter
made by any Benefited Party or on such Benefited Party's behalf, and those
covenants and agreements of the Company set forth in (j) below hereof shall
survive the repayment in full of the Benefited Obligations.

       (j) (i) The Company shall pay or reimburse the Collateral Agent and, to
the extent provided in clause (D) below, each Benefited Party, for the payment
of (A) the reasonable fees and expenses of counsel to the Collateral Agent, in
connection with the preparation, execution, delivery and administration of this
Agreement and the Security Documents and the consummation of the transactions
contemplated hereby, and in connection with advising the Collateral Agent as to
its rights and responsibilities with respect thereto, and in connection with any
amendments, waivers or consents in connection therewith, (B) all stamp and other
taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing or recording of this Agreement, the Security
Documents, and the consummation of the transactions contemplated hereby, and any
and all liabilities with respect to or resulting from any delay by the Company
in paying or omitting to pay such taxes or fees, (C) all reasonable fees and
expenses and other customary charges of the Collateral Agent for any collateral
audits performed by Collateral Agent under this Agreement or any of the
Financing Agreements, and (D) all reasonable costs and expenses of the
Collateral Agent and, following the occurrence and during the continuance of any
Event of Default, the Benefited Parties (including reasonable fees and expenses
of counsel and whether incurred through negotiations, legal proceedings or
otherwise) in connection with any amendment, waiver or enforcement of, or the
exercise or preservation of any rights under, this Agreement or the Security
Documents.  The Company shall pay the Collateral Agent all fees and expenses of
the Collateral Agent in connection with its administration and monitoring of the
Collateral, including without limitation all expenses and 

                                      -22-
<PAGE>
 
customary charges for all collateral audits. The Company hereby indemnifies and
shall hold the Benefited Parties and the Collateral Agent and their respective
officers, directors, counsel, employees and agents, harmless from and against
any and all claims, damages, losses, liabilities, costs or expenses whatsoever
which the Benefited Parties or the Collateral Agent or any such person may incur
or which may be claimed against any of them with respect to the execution,
delivery, enforcement, performance and administration of this Agreement or any
Security Document, whether before or after the occurrence of an Event of
Default; provided, however, the Company shall have no obligation pursuant to
this sentence to indemnify any such person to the extent that such claims,
damages, losses, liabilities, costs or expenses arise from the gross negligence
or willful misconduct of such person.

       (ii) In addition to the payment of expenses pursuant to J(i) above,
whether or not the transactions contemplated hereby shall be consummated, the
Company hereby indemnifies and shall hold the Benefited Parties and the
Collateral Agent and their respective officers, directors, employees and agent,
harmless from and against any and all claims, damages, losses, liabilities,
costs or expenses whatsoever (including without limitation, the reasonable fees
and disbursements of counsel) in connection with any investigative,
administrative or judicial proceeding commenced or threatened, whether or not
the Benefited Parties or the Collateral Agent or any such person shall be
designated a party thereto), which any of them may incur or which may be claimed
against any of them by reason of or in connection with this Agreement or any of
the actions contemplated hereby; provided, however, that the Company shall not
be required to indemnify any such person to the extent that claims, damages,
losses, liabilities, costs or expenses arise from the gross negligence or
willful misconduct of such person.

       (k) Each Benefited Party agrees to execute and deliver to the others any
and all such further instruments and documents and take such further actions as
may be reasonably requested, to the end that the respective terms and provisions
of this Agreement and the Security Documents may be carried out promptly and
fully.  Without limiting the generality of the foregoing, each Benefited Party
agrees to cooperate fully with each other Benefited Party in authorizing and
directing the Collateral Agent to take all actions reasonably necessary or
desirable to ensure the preservation or protection of all or any portion of the
Collateral, including without limitation, authorizing and directing expenditures
by the Collateral Agent in connection therewith and to prepare and file proofs
of claim and other pleadings and motions in connection with any insolvency
proceeding.

       (l) The Benefited Parties, the Collateral Agent, the Company and the
Grantors, after consulting or having had the opportunity to consult with counsel
knowingly, voluntarily and intentionally waive any right any of them may have to
a trail by jury in any litigation based upon or arising out of this Agreement or
any related instrument or agreement or any of the transactions contemplated by
this Agreement, or any course of conduct, dealing, statements (whether oral or
written) or actions of any of them relating to or in connection with this
Agreement or any of the Benefited Obligations secured hereby.

                                      -23-

       (m) This Agreement is a contract made under, and shall be governed by and
construed in accordance with, the laws of the State of Michigan applicable to
contracts made and to be performed entirely within such State and without giving
effect to choice of law principles of such State.  The Company, the Grantors,
the Benefited Parties, and the Collateral Agent further agree that any legal
action or proceeding with respect to this Agreement or the Security Document or
the transactions contemplated hereby may be brought in any court of the State of
Michigan, or in any court of the United States of America sitting in Michigan,
and hereby submit the United States of America sitting in Michigan, and hereby
submit to and accept generally and unconditionally the jurisdiction of those
courts with respect to its person and property, and the Company, the Grantors,
the Benefited Parties, and the Collateral Agent irrevocably consent to the
service of process in connection with any such action or proceeding by personal
delivery to the Company, the Grantors, the Benefited Parties or the Collateral
Agent or by the delivery thereof by overnight courier, postage prepaid to the
Company, the Grantors, the Benefited Party, and to the Collateral Agent in the
same manner at the addresses as set forth on signature pages hereof.  Nothing in
this paragraph shall affect the right of the Collateral Agent to serve process
in any other manner permitted by law or limit the right of the Collateral Agent
to bring any such action or proceeding against the Company or property in the
courts of any other jurisdiction.  The Company, the Grantors, the Benefited
Parties, and the Collateral Agent hereby irrevocably waive any objection to the
laying of venue of any such suit or proceeding in the above described courts.

       (n) This Agreement shall terminate when all Benefited Obligations are
paid in full, such payment is not subject to any possibility of revocation or
rescission, and the Credit Agreement and all other obligations of any of the
Benefited Parties with respect to the Benefited Obligations to lend to the
Company shall have expired or been terminated.

       (o) Headings of sections of this Agreement have been included herein for
convenience only and should not be considered in interpreting this Agreement.

       (p) Nothing in this Agreement, the Security Documents or the Subsidiary
Guaranties, expressed or implied, is intended or shall be construed to confer
upon or give to any Person other than the Benefited Parties, any right, remedy
or claim under or by reason of any such agreement or any covenant, condition or
stipulation herein or therein contained.

       (q) In case any provision in or obligation under this Agreement shall be
invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

     Each of the undersigned, R.J. Tower Corporation, Tower Automotive, Inc. and
the Subsidiary Guarantors (collectively, the "Obligors" and, individually, an
"Obligor"), hereby acknowledges and agrees to the foregoing terms and provisions
contained in this Intercreditor Agreement.  By executing this Intercreditor
Agreement, each of the Obligors agrees to be bound by the provisions thereof as
they relate to the relative rights of the Benefited Parties as among such
Benefited Parties; provided, however, that nothing in this Intercreditor
Agreement shall amend, modify, change or supersede the respective terms of the
Financing Agreements as between the Benefited Parties or any of them and any
Obligor.  In the event of any conflict or inconsistency between the terms of
this Intercreditor Agreement and the Financing Agreements, the Financing
Agreements shall govern as between the Benefited Parties thereto and such
Obligor.  Each Obligor further agrees that the terms of this Intercreditor
Agreement shall not give any Obligor any substantive rights vis a vis any
Benefited Party or the Collateral Agent and that it shall not use the violation
of this Intercreditor Agreement by any of the Parties hereto as a defense to the
enforcement by any Benefited Party under any Financing Agreement, nor assert
such violation as a counterclaim or basis for set-off or recoupment against any
of them.  Each Obligor further acknowledges and agrees that the scope of the
agency granted by this Intercreditor Agreement to the Collateral Agent hereunder
is strictly limited by this Intercreditor Agreement and is a separate and
distinct grant from the grants of agency contained in the Credit Agreement and
the Security Documents.  By its execution hereof, each Obligor hereby represents
to each of the Benefited Parties and the Collateral Agent that the execution,
delivery and performance by R.J. Tower Corporation of the Note Agreements and
the other Noteholder Documents does not constitute a violation of any of the
provisions of the Credit Agreement as in effect on the Closing Date.

Ladies and Gentlemen:

     The undersigned, R. J. Tower Corporation, a Michigan corporation (the

SECTION 1.    DESCRIPTION OF NOTES AND COMMITMENT.

     Section 1.1.  Description of Notes.  (a) The Company will authorize the

(the "Series A Notes") in the aggregate principal amount of $40,000,000 and its
7.82% Senior Secured Notes, Series B, Due June 1, 2008 (the "Series B Notes") in
the aggregate principal amount of $25,000,000. The Series A Notes and the Series
B Notes issued pursuant to this Agreement and the other separate agreements
referred to in (S)1.3 are hereinafter collectively referred to as the "Notes".

     (b) The Series A Notes will be dated the date of issue, will bear interest
from such date at the rate of 7.65% per annum, payable semiannually on the first
day of June and December in each year (commencing December 1, 1996) and at

acceleration or otherwise, until paid.  The Series B Notes will mature on
June 1, 2008  and will be substantially in the form attached hereto as
Exhibit A-2.  Interest on the Notes shall be computed on the basis of a 360-day
year of twelve 30-day months.  The Notes are not subject to prepayment or

Schedule I are hereinafter sometimes referred to as the "Purchasers".  The terms
which are capitalized herein shall have the meanings set forth in (S)8.1 unless
the context shall otherwise require.

     Section 1.2.  Commitment, Closing Date.  Subject to the terms and
conditions hereof and on the basis of the representations and warranties
hereinafter set forth, the Company agrees to issue and sell to you, and you

Purchasers. This Agreement and said similar agreements with the other Purchasers
are herein collectively referred to as the "Agreements". The obligations of each
Purchaser shall be several and not joint and no Purchaser shall be liable or
responsible for the acts of any other Purchaser.

     organization are deemed to be a single plan);

     employee benefit plans, each of which has been identified to the Company in
     writing;

          (5) you are acquiring the Notes for the account of one or more pension
     funds, trust funds or agency accounts, each of which is a "governmental

     "qualified professional asset manager" or "QPAM" (as defined in Part V of
     PTE 84-14, issued March 13, 1984), provided that no other party to the
     transactions described in this Agreement and no "affiliate" of such other
     party (as defined in Section V(c) of PTE 84-14) has at this time, and
     during the immediately preceding one year has exercised the authority to
     appoint or terminate said QPAM as manager of the assets of any plan
     identified in writing pursuant to this clause (6) or to negotiate the terms
     of said QPAM's management agreement on behalf of any such identified plans;
     or

          (7) if you are other than an insurance company, all or a portion of
     such funds consists of funds which do not constitute "plan assets".

     The Company shall deliver a certificate on the Closing Date which
certificate shall either state that (i) it is neither a "party in interest" (as
defined in Title I, Section 3(14) of ERISA) nor a "disqualified person" (as

               (ii) in the case of the issuance of any Funded Debt of the
          Company secured by Liens permitted by (S)5.9(J) and any Funded Debt of
          a Restricted Subsidiary (A) the aggregate amount of all Indebtedness
          of the Company secured by Liens permitted by (S)5.9(J) shall not
          exceed 10% of Consolidated Adjusted Net Worth and (B) the aggregate
          amount of all Indebtedness of Restricted Subsidiaries (other than
          Specified Restricted Subsidiary Indebtedness) shall not exceed 10% of
          Consolidated Adjusted Net Worth;

          (4) Current Debt of the Company and its Restricted Subsidiaries,
     provided that during the twelve-month period immediately preceding the date
     of any determination hereunder, there shall have been a period of thirty
     consecutive days during which either (i) the Company and its Restricted
     Subsidiaries shall have been free of all Current Debt or (ii) the largest

     time in good faith be prosecuting an appeal or proceeding for a review,

     Indebtedness secured by any such Lien immediately prior thereto is not
     increased above the amount then outstanding and such Lien is not extended
     to other property.

     Section 5.10.  Distributions.  (a) The Company will not and the Company
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
or through any Affiliate, declare or make or incur any liability to declare or
make any Distribution, unless, immediately after giving effect to the proposed

<PAGE>
 
               (ii) in the opinion of the Company's Board of Directors, the sale
          is for fair value and is in the best interests of the Company; and

     basis towards the prepayment at par of Senior Funded Debt (including,
     without limitation, the Notes) of the Company ranking pari passu with the
     Notes or (C) a combination of (A) and (B) above. It is understood and
     agreed by the Company and each holder of the Notes by its acceptance
     thereof that any such holder may decline any such offer of prepayment, that
     the failure of any such holder to accept or decline any such offer of
     prepayment shall be deemed to be an election by such holder to decline such
     prepayment, and that if any such offer is so accepted, the proceeds so
     offered towards the prepayment of the Notes and accepted may be prepaid at
     par notwithstanding the provisions of (S)2.2.

     The designation of a Restricted Subsidiary as an Unrestricted Subsidiary
shall be deemed and construed to constitute a sale of assets by the Company to
be consummated within the limitations provided in clause (3) of this (S)5.11(B).
Computations pursuant to this (S)5.11(B) shall include dispositions made
pursuant to (S)5.11(C) and computations pursuant to (S)5.11(C) shall include
dispositions made pursuant to this (S)5.11(B).

purchase stock or other Securities exchangeable for or convertible into common
stock of the Company or any Restricted Subsidiary) of a Restricted Subsidiary
(said stock, options, warrants and other Securities herein called "Subsidiary
Stock") or sell or otherwise transfer any Indebtedness of the Company or of a
Restricted Subsidiary, nor will any Restricted Subsidiary issue, sell, pledge or
otherwise dispose of any shares of its own Subsidiary Stock, provided that the
foregoing restrictions do not apply to:

          (1) the issue of directors' qualifying shares; or

          (2) the issue of Subsidiary Stock to the Company or any Wholly-owned
     Restricted Subsidiary; or

                                      -19-

          (3) the sale or other disposition at any one time to a Person of the
     entire Investment of the Company and its other Restricted Subsidiaries in
     any Restricted Subsidiary if all of the following conditions are met:

               (i) the assets (valued at current book value) of such Restricted
          Subsidiary so sold or otherwise disposed of do not, together with all
          other assets of the Company and its Restricted Subsidiaries previously
          disposed of during the same fiscal year (other than in the ordinary
          course of business), exceed 10% of Consolidated Total Assets,
          determined as of the end of the immediately preceding fiscal year;

                (ii) in the opinion of the Company's Board of Directors, the
          sale is for fair value and is in the best interests of the Company;

                (iii)  immediately after the consummation of the transaction
          and after giving effect thereto, such Restricted Subsidiary shall hold
          no Indebtedness of, nor shall it have a continuing Investment in the
          Capital Stock of, the Company or of any Restricted Subsidiary and any
          such Indebtedness or Investment shall have been discharged in full or
          acquired in its entirety, as the case may be, by the Company or a
          Restricted Subsidiary; and

                (iv) immediately after the consummation of the transaction and
          after giving effect thereto, (A) no Default or Event of Default would
          exist, and (B) the Company would be permitted by the provisions of
          (S)5.8(A)(3) to incur at least $1.00 of additional Funded Debt; or

          (4) the sale or other transfer in its entirety of Indebtedness of the
     Company or a Restricted Subsidiary owing to a Restricted Subsidiary by such
     Restricted Subsidiary to the Company or another Wholly-owned Restricted
     Subsidiary;

     provided, however, that for purposes of the foregoing calculation, there
     shall not be included any assets the proceeds of which were or are applied
     within 180 days of the date of sale of such assets to either (A) the
     acquisition of assets (including any Capital Stock of any entity which
     becomes a Restricted Subsidiary pursuant to such acquisition) intended to
     be used in the operation of the business of the Company and its Restricted
     Subsidiaries as described in (S)5.5 and having a fair market value (as
     determined in good faith by the Board of Directors of the Company) at least
     equal to that of the assets so disposed of or (B) offered on a pro-rata
     basis towards the prepayment at par of Senior Funded Debt (including,
     without limitation, the Notes) of the Company ranking pari passu with the
     Notes or (C) a combination of (A) and (B) above.  It is understood and
     agreed by the Company and each holder of the Notes by its acceptance
     thereof that any such holder may decline any such offer of prepayment, that
     the failure of any such holder to accept or decline any such offer of
     prepayment shall be deemed to be an election by such holder to decline such
     prepayment, and that if any such offer is so accepted, the proceeds so
     offered towards the prepayment of the Notes and accepted may be prepaid at
     par notwithstanding the provisions of (S)2.2.

limitation, the purchase from, sale to or exchange of property with, or the
rendering of any service by or for, any Affiliate), except pursuant to the
reasonable requirements of the Company's or such Restricted Subsidiary's
business and upon fair and reasonable terms no less favorable to the Company or
such Restricted Subsidiary than would obtain in a comparable arm's-length
transaction with a Person other than an Affiliate; provided, that nothing
contained in this (S)5.13 shall be deemed or construed to prohibit the Company
from paying reasonable fees and expenses to Hidden Creek Industries, a New York

in respect of any Note, the holder thereof, may, by notice in writing sent to
the Company in the manner provided in (S)9.6, declare the entire principal and
all interest accrued on such Note to be, and such Note shall thereupon become
forthwith due and payable, without any presentment, demand, protest or other
notice of any kind, all of which are hereby expressly waived.  When any Event of
Default described in paragraphs (a) through (l), inclusive, of said (S)6.1 has
happened and is continuing, the holder or holders of 25% or more of the
principal amount of the Notes at the time outstanding may, by notice in writing

right or otherwise prejudice such holder's rights, powers and remedies.  The
Company further agrees, to the extent permitted by law, to pay to the holder or

of any Notes upon any default hereunder or thereon, including reasonable

Event of Default described in paragraphs (a) through (l), inclusive, of (S)6.1,
the holders of 76% in aggregate principal amount of the Notes then outstanding

     Section 9.7.  Indemnification.  The Company does hereby indemnify and
hold harmless you, your directors, trustees, officers, employees and each
Person, if any, who controls you within the meaning of the Securities Act of
1933, as amended, or the Exchange Act (any and all of whom are referred to as
the "Indemnified Party") from and against any and all losses, claims, damages
and liabilities, joint or several (including all legal fees or other expenses
reasonably incurred by any Indemnified Party in connection with the preparation
for or defense of any pending or threatened claim, action or proceeding, whether
or not resulting in any liability), to which such Indemnified Party may become
subject (whether or not such Indemnified Party is a party thereto) under any
applicable Federal, state or local law or otherwise caused by or arising out of,
or allegedly caused by or arising out of, this Agreement or any transaction
contemplated hereby, other than losses, claims, damages or liabilities resulting
from such representation made by you in (S)3.2, or the transfer of any Notes in
violation of any applicable law or regulation.

     Promptly after receipt by an Indemnified Party of notice of any claim,
action or proceeding with respect to which an Indemnified Party is entitled to
indemnity hereunder, such Indemnified Party will notify the Company of such
claim or the commencement of such action or proceeding, provided that the
failure of an Indemnified Party to give notice as provided herein shall not
relieve the Company of its obligations under this (S)9.7 with respect to such
Indemnified Party, except to the extent that the Company is actually prejudiced
by such failure.  The Company will assume the defense of such claim, action or
proceeding and will employ counsel satisfactory to the Indemnified Party and
will pay the fees and expenses of such counsel.  Notwithstanding the preceding
sentence, the Indemnified Party will be entitled, at the expense of the Company,
to employ counsel separate from counsel for the Company and for any other party
in such action if the Indemnified Party reasonably determines that a conflict of
interest or other reasonable basis exists which makes representation by counsel
chosen by the Company not advisable, provided that the Company shall not be
obligated to pay for the fees and expenses of more than one counsel for all
Indemnified Parties.  In the event an Indemnified Party appears as a witness in
any action or proceeding brought against the Company (or any of its officers,
directors or employees) in which an Indemnified Party is not named as a
defendant, the Company agrees to reimburse such Indemnified Party for all
expenses incurred by it (including fees and expenses of counsel) in connection
with its appearing as a witness.

representations and warranties made by the Company herein and in any

the Notes.

reason be declared invalid or unenforceable, such decision shall not affect the
validity or enforceability of any remaining portion, which remaining portion
shall remain in force and effect as if this Agreement had been executed with the
invalid or unenforceable portion thereof eliminated.

                         REPRESENTATIONS AND WARRANTIES

       The Company represents and warrants to you as follows:

       1. Subsidiaries.  Schedule II attached to the Agreements states the name
of each of the Company's Subsidiaries, its jurisdiction of incorporation and the
percentage of its Voting Stock owned by the Company and/or its Subsidiaries.
Those Subsidiaries listed in Section 1 of Part C of said Schedule II constitute
Restricted Subsidiaries.  The Company and each Subsidiary has good and
marketable title to all of the shares it purports to own of the stock of each
Subsidiary, free and clear in each case of any Lien.  All such shares have been
duly issued and are fully paid and non-assessable.

       2. Corporate Organization and Authority.  The Company, and each
Restricted Subsidiary,

            (a) is a corporation duly organized, validly existing and in good
          standing under the laws of its jurisdiction of incorporation;

            (b) has all requisite power and authority and all necessary licenses
     and permits to own and operate its properties and to carry on its business
     as now conducted and as presently proposed to be conducted; and

            (c) is duly licensed or qualified and is in good standing as a
     foreign corporation in each jurisdiction in which the failure to so qualify
     would have a material adverse effect on the properties, business,
     prospects, profits or condition (financial or otherwise) of the Company and
     its Subsidiaries, taken as a whole.

       3. Business and Property.  The Offering Memorandum dated May, 1996 (the
"Memorandum") prepared by BA Securities, Inc. generally sets forth the business
conducted and proposed to be conducted by the Company and its Subsidiaries and
the principal properties of the Company and its Subsidiaries.

       4. Financial Statements.  (a) The consolidated balance sheets of Tower
Automotive and its consolidated subsidiaries as of December 31, 1994 and
December 31, 1995 and the statements of operations, stockholders' investment and
cash flows for the fiscal years ended on said dates, each accompanied by a
report thereon containing an opinion unqualified as to scope limitations imposed
by Tower Automotive and otherwise without qualification except as therein noted,
by Arthur Andersen LLP, have been prepared in accordance with GAAP consistently
applied except as therein noted, present fairly the financial position of Tower
Automotive and its consolidated subsidiaries as of such dates and the results of
their operations and changes in their cash flows for such periods.  The
unaudited consolidated balance sheets of Tower Automotive and its consolidated
subsidiaries as of March 31, 1996, and the unaudited statements of operations
and cash flows for the three-month period ended on said date prepared by Tower
Automotive have been prepared in accordance with GAAP consistently applied,
include normal recurring adjustments and reflect all adjustments which are, in
the opinion of Tower 



                                   Exhibit B
                              (to Note Agreement)

<PAGE>
 
Automotive's management, necessary for a fair presentation of the financial
position of Tower Automotive and its consolidated subsidiaries as of said date
and the results of their operations and changes in their cash flows for such
period.

       (b) Since December 31, 1995, there has been no change in the condition,
financial or otherwise, of Tower Automotive and its consolidated subsidiaries as
shown on the consolidated balance sheet as of such date except (i) the
acquisition of Trylon Corporation on January 16, 1996 and (ii) changes in the
ordinary course of business, none of which individually or in the aggregate has
been materially adverse.

       (c) In furtherance of the representations contained in clauses (a) and
(b) of this paragraph 4 and without limiting the same, the estimates and
projections contained in the Memorandum are based upon assumptions that the
Company considers reasonable and prudent and customary for corporations of
established reputation engaged in the same or a similar business and owning and
operating similar properties as the Company.

       5. Indebtedness.  Schedule II attached to the Agreements correctly
describes all Indebtedness (including, without limitation, all secured
Indebtedness), Capitalized Leases and operating leases of the Company and its
Restricted Subsidiaries outstanding on the Closing Date.

       6. Full Disclosure.  Neither the financial statements referred to in
paragraph 4 hereof nor the Agreements, the Memorandum or any other written
statement furnished by the Company to you in connection with the negotiation of
the sale of the Notes, contains any untrue statement of a material fact or omits
a material fact necessary to make the statements contained therein or herein not
misleading.  There is no fact peculiar to the Company or its Subsidiaries which
the Company has not disclosed to you in writing which materially affects
adversely and which, so far as the Company can now foresee, will materially
affect adversely the properties, business, prospects, profits or condition
(financial or otherwise) of the Company and its Restricted Subsidiaries, taken
as a whole.

       7. Pending Litigation.  There are no proceedings pending or, to the
knowledge of the Company, threatened against or affecting the Company or any
Restricted Subsidiary in any court or before any governmental authority or
arbitration board or tribunal which involve the possibility of materially and
adversely affecting the properties, business, prospects, profits or condition
(financial or otherwise) of the Company and its Restricted Subsidiaries, taken
as a whole, or impairing the ability of the Company to issue and deliver the
Notes or to comply with the provisions of the Agreements, the Collateral
Documents or the Intercreditor Agreement or impairing the ability of the
Restricted Subsidiaries to comply with the provisions of the Subsidiary
Guaranties.  Neither the Company nor any Restricted Subsidiary has received
notice in respect of, nor does it have any knowledge of, any default with
respect to any judgment, order, writ, injunction, or decree of any court,
governmental authority or arbitration board or tribunal that, in the aggregate,
could reasonably be expected to have a material adverse effect on the
properties, business, prospects, profits or condition (financial or otherwise)
of the Company and its Subsidiaries, taken as a whole.

                                      B-2

<PAGE>
 
       8. Title to Properties.  To the best knowledge of the Company, the
Company and each Restricted Subsidiary has good and marketable title in fee
simple (or its equivalent under applicable law) to all parcels of real property
and has good title to all the other items of property it purports to own,
including that reflected in the most recent balance sheet referred to in
paragraph 4 hereof, except (a) as sold or otherwise disposed of in the ordinary
course of business, (b) Liens permitted by the Agreements and (c) Liens and
defects which could not reasonably be expected to have a material adverse effect
on the properties, business, prospects, profits or condition (financial or
otherwise) of the Company and its Subsidiaries, taken as a whole.  The Company
and each Restricted Subsidiary enjoys peaceful and undisturbed possession of all
property which is leased by it and which is material for the operation of its
respective business.

       9. Insurance.  The Company and each of its Restricted Subsidiaries
maintain the insurance coverage required by (S)5.2 of the Agreements as more
fully described in Schedule II attached to the Agreements and maintain all
insurance coverage otherwise required by the applicable provisions of the
Collateral Documents.

       10.  Patents and Trademarks.  To the best knowledge of the Company, the
Company and each Restricted Subsidiary owns or possesses all the patents,
trademarks, trade names, service marks, copyrights, licenses and rights with
respect to the foregoing, except where the failure to so own or possess would
not have a material adverse effect on the properties, business, prospects,
profits or condition (financial or otherwise) of the Company and its
Subsidiaries, taken as a whole, without any material known conflict with the
rights of others.

       11.  Sale Is Legal and Authorized.  (a)  The sale of the Notes and
compliance by the Company with all of the provisions of the Agreements, the
Collateral Documents, the Intercreditor Agreement and the Notes--

            (i) are within the corporate powers of the Company; and

            (ii) will not violate any provisions of any law or any order of any
     court or governmental authority or agency and will not conflict with or
     result in any breach of any of the provisions of or constitute a default
     under or result in the creation or imposition of any Lien upon any of the
     property of the Company pursuant to the provisions of the Certificate of
     Incorporation or By-laws of the Company or any indenture or other agreement
     or instrument to which the Company is a party or by which it may be bound;
     and

       (b) the Notes, the Agreements, the Collateral Documents and the
Intercreditor Agreement have been duly authorized by proper corporate action on
the part of the Company (no action by the stockholders of the Company being
required by law, by the Certificate of Incorporation or By-laws of the Company
or otherwise), have been duly executed and delivered by the Company and
constitute the legal, valid and binding obligations, contracts and agreements of
the Company enforceable in accordance with their respective terms.

                                      B-3

<PAGE>
 
       12.  No Defaults.  No Default or Event of Default has occurred and is
continuing.  Neither the Company nor any of its Subsidiaries is in default in
the payment of principal or interest on any Indebtedness.  Neither the Company
nor any of its Subsidiaries is in default under any other instrument or
instruments or agreements under and subject to which any Indebtedness has been
issued and no event has occurred and is continuing under the provisions of any
such instrument or agreement which with the lapse of time or the giving of
notice, or both, would constitute an event of default thereunder, which default
or event could reasonably be expected to have a material adverse effect on the
properties, business, prospects, profits or condition (financial or otherwise)
of the Company and its Subsidiaries, taken as a whole.

       13.  Governmental Consent.  No approval, consent or withholding of
objection on the part of any regulatory body, state, Federal or local, is
necessary in connection with the execution and delivery by the Company of the
Agreements, the Collateral Documents or the Intercreditor Agreement or the
issuance, sale or delivery of the Notes or compliance by the Company with any of
the provisions of the Agreements, the Collateral Documents, the Intercreditor
Agreement or the Notes.

       14.  Taxes.  All tax returns required to be filed by the Company or any
Subsidiary in any jurisdiction have, in fact, been filed, and all taxes,
assessments, fees and other governmental charges upon the Company or any
Subsidiary or upon any of their respective properties, income or franchises,
which are shown to be due and payable in such returns have been paid, except:
(i) those presently payable without penalty or interest, (ii) those presently
being contested in good faith by appropriate proceedings diligently conducted
for which such reserves or other appropriate provision, if any, as shall be
required by GAAP shall have been made, and (iii) those which the failure to file
or pay will not have a material adverse effect on the properties, business,
prospects, profits or condition (financial or otherwise) of the Company and its
Subsidiaries, taken as a whole.  For all taxable years ending on or before
December 31, 1991, the Federal income tax liability of the Company and its
Subsidiaries has been satisfied and either the period of limitations on
assessment of additional Federal income tax has expired or the Company and its
Subsidiaries have entered into an agreement with the Internal Revenue Service
closing conclusively the total tax liability for the taxable year.  The Company
does not know of any proposed additional tax assessment against it for which
adequate provision has not been made on its accounts, and no material
controversy in respect of additional Federal or state income taxes due since
said date is pending or to the knowledge of the Company threatened.  The
provisions for income taxes on the books of the Company and each Subsidiary are
adequate for all open years and for its current fiscal period, and the
provisions for all other taxes on the books of the Company and each Subsidiary
are adequate in all material respects for all open years and for its current
fiscal period.

       15.  Use of Proceeds.  The net proceeds from the sale of the Notes will
be used to finance the acquisition of MascoTech as more fully described in the
Memorandum and for general working capital.  None of the transactions
contemplated in the Agreements (including, without limitation thereof, the use
of proceeds from the issuance of the Notes) will violate or result in a
violation of Section 7 of the Exchange Act or any regulation issued pursuant
thereto, including, without limitation, Regulations G, T and X of the Board of
Governors of the Federal Reserve System, 12 C.F.R., Chapter II.  Neither the
Company nor any Subsidiary owns or 

                                      B-4

<PAGE>
 
intends to carry or purchase any "margin stock" within the meaning of said
Regulation G. None of the proceeds from the sale of the Notes will be used to
purchase, or refinance any borrowing the proceeds of which were used to
purchase, any "security" within the meaning of the Exchange Act.

       16.  Private Offering.  Neither the Company, directly or indirectly, nor
any agent on its behalf has offered or will offer the Notes, the Subsidiary
Guaranties or any similar Security to or has solicited or will solicit an offer
to acquire the Notes, the Subsidiary Guaranties or any similar Security from or
has otherwise approached or negotiated or will approach or negotiate in respect
of the Notes, the Subsidiary Guaranties or any similar Security with any Person
other than the Purchasers and not more than 60 other institutional investors,
each of whom was offered a portion of the Notes at private sale for investment.

Company to perform its obligations under the Agreements, the Collateral
Documents, the Intercreditor Agreement and the Notes and neither the Company nor

regulation to which it is subject; or (2) has failed to obtain any license,
permit, franchise or other governmental authorization necessary to the ownership
of its property or to the conduct of its business, which violation or failure to

Subsidiaries, taken as a whole, or impair the ability of the Company to perform
its obligations contained in the Agreements, the Collateral Documents, the
Intercreditor Agreement or the Notes.  Neither the Company nor any Subsidiary is

Subsidiaries are, to the best knowledge of the Company, in compliance with all
applicable Environmental Laws, the failure to comply with which would materially

Company and its Subsidiaries subject only to encumbrances expressly permitted by
the terms of the Agreements and such Collateral Documents.

       26.  Solvency.  (a) The Company is solvent, has capital not unreasonably
small in relation to its business or any contemplated or undertaken transaction

Company's probable liability on its existing debts as they become absolute and
matured.  The Company does not intend to incur or believe or should have
believed that it will incur, debts beyond its ability to pay such debts as they
become due.  The Company will not be rendered insolvent by the execution,
delivery and performance of its obligations under the Agreements, the Collateral
Documents, the Intercreditor Agreement or the Notes.  The Company does not

irrevocably guarantees to the Noteholders the due and punctual payment to the
Noteholders when due, whether by acceleration or otherwise, of all amounts,
including, without limitation, principal, premium, if any, interest (including
interest accruing on or after the filing of any petition in bankruptcy, or the
commencement of any insolvency, reorganization or like proceeding by the
Company, whether or not a claim for post-filing or post-petition interest is
allowed in such a proceeding), and all other liabilities and obligations, direct
or indirect, absolute or contingent, due or to become due, now existing or

by the Noteholders and all reasonable expenses, including reasonable attorneys'
fees, that may be incurred by the Noteholders and in enforcing such covenant,
representation or warranty of the Company and in enforcing the covenants and
agreements of this Guaranty.

Section 3.  Unconditional Character of Guaranty.

     (a) The obligations of each Guarantor under this Guaranty shall be
absolute and unconditional, and shall be a guaranty of payment and performance
and not of collection, irrespective of the validity, regularity or
enforceability of the Notes and the Note Agreements or any provision thereof,
the absence of any action to enforce the same, any waiver or consent with
respect to or any amendment of any provision thereof, the recovery of any
judgment against any Person or action to enforce the same, any failure or delay
in the enforcement of the obligations of the Company under the Notes or the Note
Agreements, or any setoff, counterclaim, recoupment, limitation, defense or
termination, whether with or without notice to any of the Guarantors.  Each of
the Guarantors hereby waives diligence, demand for payment, filing of claims
with any court, any proceeding to enforce any provision of the Notes executed by
the Company, or the Note Agreements, any right to require a proceeding first
against the Company or against any other guarantor or other party providing
collateral, or to exhaust any security for the performance of the obligations of
the Company, any protest, presentment, notice or demand 

                                      -2-
<PAGE>
 
whatsoever, and each of the Guarantors hereby covenants that this Guaranty shall
not be terminated, discharged or released except, subject to Section 7.7 hereof,
upon final payment in full in cash subject to no revocation or rescission of all
amounts due and to become due from the Company, as and to the extent described
in Section 2 above, and only to the extent of any such payment, performance and
discharge. Each of the Guarantors further covenants that no security now or
subsequently held by the Noteholders for the payment of the Indebtedness
evidenced by the Notes made by the Company under the Note Agreements, or for the
payment of any other Indebtedness of the Company to the Noteholders under the
Note Agreements, whether in the nature of a security interest, pledge, lien,
assignment, setoff, suretyship, guaranty, indemnity, insurance or otherwise, and
no act, omission or other conduct of Noteholders in respect of such security
(excluding fraud, gross negligence or willful misconduct), shall affect in any
manner whatsoever the unconditional obligation of this Guaranty, and the right
of each of the Noteholders to enforce the same, in their respective sole
discretion and without notice to any of the Guarantors, may release, exchange,
enforce, apply the proceeds of and otherwise deal with any such security without
affecting in any manner the unconditional obligation of this Guaranty.

     (b) Without limiting the generality of the foregoing, such obligations,
and the rights of the Noteholders to enforce the same, by proceedings, whether
by action at law, suit in equity or otherwise, shall not be in any way affected
by:

          (i) any insolvency, bankruptcy, liquidation, reorganization,
     readjustment, composition, dissolution, winding up or other proceeding
     involving or affecting the Company or others; or

          (ii) any change in the ownership of any of the capital stock of the
     Company any other party providing collateral for any indebtedness covered
     by this Guaranty, or any of their respective Affiliates; or

          (iii)  any default, failure or delay, willful or otherwise, in the
     performance by the Company or any other Person of any obligations of any
     kind or character whatsoever of the Company or any other Person (including,
     without limitation, the obligations and undertakings of the Company or any
     other Person under the Notes or  the Note Agreements); or

          (iv) impossibility or illegality of performance on the part of the
     Company or any other Person of its obligations under the Notes or the Note
     Agreements or any other instrument; or

          (v) in respect of the Company or any other Person, any change of
     circumstances, whether or not foreseen or foreseeable, whether or not
     imputable to the Company or any other Person, or other impossibility of
     performance through fire, explosion, accident, labor disturbance, floods,
     droughts, embargoes, wars (whether or not declared), civil commotions, acts
     of God or the public enemy, delays or failure of suppliers or carriers,
     inability to obtain materials, action of any Federal or state regulatory
     body or agency, change of law or any other causes affecting performance, or
     any other 

                                      -3-
<PAGE>
 
     force majeure, whether or not beyond the control of the Company or any
     other Person and whether or not of the kind hereinbefore specified; or

          (vi) any attachment, claim, demand, charge, Lien, order, process,
     encumbrance or any other happening or event or reason, similar or
     dissimilar to the foregoing, or any withholding or diminution at the
     source, by reason of any taxes, assessments, expenses, indebtedness,
     obligations or liabilities of any character, foreseen or unforeseen, and
     whether or not valid, incurred by or against any Person, or any claims,
     demands, charges or Liens of any nature, foreseen or unforeseen, incurred
     by any Person, or against any sums payable under this Guaranty, so that
     such sums would be rendered inadequate or would be unavailable to make the
     payments herein provided; or

          (vii)  any order, judgment, decree, ruling or regulation (whether or
     not valid) of any court of any nation or of any political subdivision
     thereof or any body, agency, department, official or administrative or
     regulatory agency of any thereof or any other action, happening, event or
     reason whatsoever which shall delay, interfere with, hinder or prevent, or
     in any way adversely affect, the performance by any party of its respective
     obligations under the Notes or the Note Agreements or any instrument
     relating thereto; or

          (viii)  the failure of any of the Guarantors to receive any benefit
     from or as a result of its execution, delivery and performance of this
     Guaranty; or

          (ix) any act or failure to act with regard to the Notes or the Note
     Agreements or anything which might vary the risk of any of the Guarantors;
     or

          (x) any other circumstance which might otherwise constitute a
     defense available to, or a discharge of, any of the Guarantors in respect
     of the obligations of such Guarantor under this Guaranty;

provided, that the specific enumeration of the above-mentioned acts, failures or
omissions shall not be deemed to exclude any other acts, failures or omissions,
though not specifically mentioned above, it being the purpose and intent of this
Guaranty that the obligations of the Guarantors shall be absolute and
unconditional and shall not be discharged, impaired or varied except by the
payment in cash of the principal of, premium, if any, and interest on the Notes
in accordance with their respective terms whenever the same shall become due and
payable as in the Notes provided and all other sums due and payable under the
Note Agreements, at the place specified in and all in the manner and with the
effect provided in the Notes and the Note Agreements, as amended or modified
from time to time.  Without limiting the foregoing, it is understood that
repeated and successive demands may be made and recoveries may be had hereunder
as and when, from time to time, the Company shall default under the terms of the
Notes or the Note Agreements and that notwithstanding recovery hereunder for or
in respect of any given Default or Defaults by the Company under the Notes or
the Note Agreements, this Guaranty shall remain in full force and effect and
shall apply to each and every subsequent Default.

                                      -4-
<PAGE>
 
     (c) Each of the Guarantors hereby waives to the fullest extent possible
under applicable law:

          (i) any defense based upon the doctrine of marshalling of assets or
     upon an election of remedies by the Noteholders, including, without
     limitation, an election to proceed by non-judicial rather than judicial
     foreclosure;

          (ii) any defense based upon any statute or rule of law which
     provides that the obligation of a surety must be neither larger in amount
     nor in other respects more burdensome than that of the principal;

          (iii)  any duty on the part of any of the Noteholders to disclose to
     the Guarantors any facts the Noteholders may now or hereafter know about
     the Company regardless of whether any Noteholder has reason to believe that
     any such facts materially increase the risk beyond that which each of the
     Guarantors intends to assume or has reason to believe that such facts are
     unknown to any of the Guarantors or has a reasonable opportunity to
     communicate such facts to each of the Guarantors, since each of the
     Guarantors acknowledges that it is fully responsible for being and keeping
     informed of the financial condition of the Company and of all circumstances
     bearing on the risk of non-payment of any Indebtedness hereby guaranteed;

          (iv) any claim for reimbursement, contribution, exoneration,
     indemnity or subrogation, or any other similar claim, which any such
     Guarantor may have or obtain against the Company by reason of the existence
     of this Guaranty, or by reason of the payment by any of the Guarantors of
     any Indebtedness or the performance of this Guaranty;

          (v) any other event or action (excluding any of the Guarantors'
     compliance with the provisions hereof) that would result in the discharge
     by operation of law or otherwise of any of the Guarantors from the
     performance or observance of any obligation, covenant or agreement
     contained in this Guaranty; and

          (vi) notice of acceptance of this Guaranty by the Noteholders or of
     the creation, renewal or accrual of any liability of the Company, present
     or future, or of the reliance of such Noteholders upon this Guaranty (it
     being understood that every indebtedness, liability and obligation
     described in Section 2 hereof shall conclusively be presumed to have been
     created, contracted or incurred in reliance upon the execution of this
     Guaranty).

     (d) Each of the Noteholders may deal with the Company and any security
held by them for the obligations of the Company (as aforesaid), in the same
manner and as freely as if this Guaranty did not exist and the Noteholders
without notice to any of the Guarantors, among other things, to grant to the
Company such extension or extensions of time to perform any act or acts as may
seem advisable to Noteholder at any time and from time to time, and to permit
the Company to incur additional indebtedness owed to the Noteholders, or any one
of them, 

                                      -5-
<PAGE>
 
without terminating, affecting or impairing the validity or enforceability of
this Guaranty or the obligations of the Guarantors hereunder.

     (e) Each Noteholder may proceed, either in its own name or in the name of
one or more of the Guarantors, or otherwise, to protect and enforce any or all
of its rights under this Guaranty by suit in equity, action at law or by other
appropriate proceedings, or to take any action authorized or permitted under
applicable law, and shall be entitled to require and enforce the performance of
all acts and things required to be performed hereunder by the Guarantors.  Each
and every remedy of the Noteholders shall, to the extent permitted by law, be
cumulative and shall be in addition to any other remedy given hereunder or now
or hereafter existing at law or in equity.

     (f) No waiver or release shall be deemed to have been made by any of the
Noteholders of any of its rights hereunder unless the same shall be in writing
and signed by all of the Noteholders and any such waiver shall be a waiver or
release only with respect to the specific matter involved and shall in no way
impair the rights of any of the Noteholders or the obligations of the Guarantors
under this Guaranty in any other respect at any other time.

     (g) At the option of the Noteholders, each of the Guarantors may be
joined in any action or proceeding commenced by the Noteholders against the
Company or any of the other parties providing collateral for any indebtedness
covered by this Guaranty in connection with or based upon the Notes made by the
Company, the Note Agreements or other Indebtedness, or any provision thereof,
and recovery may be had against each of the Guarantors in such action or
proceeding or in any independent action or proceeding against each of the
Guarantors, without any requirement that the Noteholders first assert, prosecute
or exhaust any remedy or claim against the Company and/or any other party
providing collateral for any Indebtedness covered by this Guaranty.

     (h) As a separate, additional and continuing obligation, each of the
Guarantors unconditionally and irrevocably undertakes and agrees with the
Noteholders that, should the amounts referred to in Section 2 of this Guaranty
not be recoverable from such Guarantor in its capacity as a guarantor under this
Guaranty for any reason whatsoever (including, without limitation, by reason of
any provision of the Notes or the Note Agreements, being or becoming void,
unenforceable, or otherwise invalid under any applicable law) then,
notwithstanding any knowledge thereof by the Noteholders or any of them at any
time, such Guarantor as sole, original and independent obligor, upon demand by
the Noteholders, will make payment to the Noteholders of all such amounts, by
way of a full indemnity.

     (i) Subject to the limitations on the rights of a Noteholder to transfer
or assign the Notes, as more particularly described in the Note Agreements, all
rights of any Noteholder may be transferred or assigned at any time and shall be
considered to be transferred or assigned at any time or from time to time upon
the transfer of such Note in accordance with the terms of the Note Agreements
whether with or without the consent of or notice to the Guarantors under this
Guaranty or to the Company.

                                      -6-
<PAGE>
 
     (j) To the extent of any payments made under this Guaranty, each of the
Guarantors shall be subrogated to the rights of the holder of the Notes
receiving such payments, but each of the Guarantors covenants and agrees that
such right of subrogation shall be subordinate in right of payment to the rights
of any Noteholders for which full payment has not been made or provided for and,
to that end, each of the Guarantors agrees not to claim or enforce any such
right of subrogation or any right of setoff or any other right which may arise
on account of any payment made by such Guarantor in accordance with the
provisions of this Guaranty, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution or indemnification and any
right to participate in any claim or remedy of any Noteholder or Noteholders
against the Company, whether or not such claim, remedy or right arises in equity
or under contract, statute or common law, including, without limitation, the
right to take or receive from the Company, directly or indirectly, in cash or
other property or by set-off or in any other manner, payment or security on
account of such claim, remedy or right unless and until 366 days after all of
the Notes owned by Persons other than the Guarantors and all other sums due or
payable under the Note Agreements have been fully paid and discharged or payment
therefor has been provided.  If any amount shall be paid to a Guarantor in
violation of the preceding sentence at any time prior to the later of the
indefeasible cash payment in full of the Notes and all other amounts payable
under the Note Agreements and this Guaranty, such amounts shall be held in trust
for the benefit of the Noteholders and shall forthwith be paid to the
Noteholders to be credited and applied to the amounts due or to become due with
respect to the Notes and all other amounts payable under the Note Agreements and
this Guaranty, whether matured or unmatured.  Each of the Guarantors
acknowledges that it has received direct and indirect benefits from the
financing arrangements contemplated by the Note Agreements and that the waiver
set forth in this subsection is knowingly made as a result of the receipt of
such benefits.

     (k) Each of the Guarantors agrees that to the extent the Company, or any
other Person makes any payment on any Note, which payment or any part thereof is
subsequently invalidated, voided, declared to be fraudulent or preferential, set
aside, recovered, rescinded or is required to be retained by or repaid to a
trustee, receiver, or any other Person under any bankruptcy code, common law, or
equitable cause, then and to the extent of such payment, the obligation or the
part thereof intended to be satisfied shall be revived and continued in full
force and effect with respect to such Guarantor's obligations hereunder, as if
said payment had not been made.  The liability of such Guarantor hereunder shall
not be reduced or discharged, in whole or in part, by any payment to any
Noteholder from any source that is thereafter paid, returned or refunded in
whole or in part by reason of the assertion of a claim of any kind relating
thereto, including, but not limited to, any claim for breach of contract, breach
of warranty, preference, illegality, invalidity, or fraud asserted by any
account debtor or by any other Person.

     (l) The obligations of each of the Guarantors under this Guaranty rank
pari passu in right of payment with all other indebtedness for borrowed money
(actual or contingent) of the respective Guarantor which is not secured or the
subject of any statutory trust or preference or which is not expressly
subordinated in right of payment to any other indebtedness for borrowed money.

                                      -7-

Section 4.  Benefit of the Notes.

     Each of the Guarantors is a Subsidiary of the Company.  The Company has

     2.3.  Piggyback Registration.  If the Company proposes to file a
registration statement under the 1933 Act with respect to an offering of Common
Stock (i) for the Company's own account (other than a registration statement on
Form S-4 or S-8 (or any substitute form that may be adopted by the Commission))
or (ii) for the account of any of its holders of Common Stock, then the Company
shall give written notice of such proposed filing to MascoTech as soon as
practicable (but in no event less than 10 calendar days before the anticipated
filing date), and such notice shall offer MascoTech the opportunity to register
such number of Registrable Securities as MascoTech may request on the same terms
and conditions as the Company's or such holder's Common Stock (a "PIGGYBACK
REGISTRATION").

     2.4.  Reduction of Offering.  Notwithstanding anything contained herein, if
the managing Underwriter of an offering described in Section 2.3 delivers a
written opinion to the Company that the size of the offering that MascoTech, the
Company and any other Persons intend to make is such that the success of the
offering would be materially and adversely affected, then the amount of
Registrable Securities to be offered for the account of MascoTech shall be
reduced to the extent necessary to reduce the total amount of securities to be
included in such offering to the amount recommended by such managing
Underwriter; provided that if securities are being offered for the account of
Persons other than the Company and MascoTech, then the proportion by which the
amount of such Registrable Securities intended to be offered for the account of
MascoTech is reduced shall not exceed the proportion by which the amount of such
securities intended to be offered for the account of such other Persons is
reduced.

     2.5.  Third Party Registration Rights.  Prior to the consummation of any
Organic Change, the Company shall make appropriate provision to insure that, so
long as 

                                       4
<PAGE>
 
this Agreement is in effect, MascoTech and each Person to whom the registration
rights granted hereby have been or may be assigned pursuant to the terms hereof
is granted registration rights equivalent to those granted hereby with respect
to all securities of any Person other than the Company that: (i) as a result of
the operation of Section 2B of the Stock Purchase Warrants, may be issued or
issuable upon exercise of the Warrants or (ii) as a result of such Organic
Change may be acquired or acquirable with respect to or in exchange for
Registrable Securities of the Company.

                                  ARTICLE III

                            REGISTRATION PROCEDURES

     3.1.  Filings; Information.  Whenever MascoTech requests that any
Registrable Securities be registered pursuant to Sections 2.1 or 2.3 or with
respect to the Shelf Registration Statement, the Company will use its best
efforts to effect the registration and the sale of such Registrable Securities
in accordance with the intended method of disposition thereof as quickly as
practicable and in connection with any such request and the Shelf Registration
Statement, the Company and MascoTech agree as follows:

           (a)  The Company will, prior to filing a registration statement or
     prospectus or any amendment or supplement thereto, furnish to MascoTech and
     each applicable managing Underwriter, if any, without charge, copies
     thereof, and thereafter furnish to MascoTech and each such Underwriter, if
     any, without charge, such number of copies of such registration statement,
     each amendment and supplement thereto (in each case including all exhibits
     thereto and documents incorporated by reference therein) and the prospectus
     included in such registration statement (including each preliminary
     prospectus) and such other documents as MascoTech or each such Underwriter
     may reasonably request in order to facilitate the disposition of the
     Registrable Securities.

           (b)  After the filing of the registration statement, the Company will
     promptly notify MascoTech of any stop order issued or, to the knowledge of
     the Company, threatened to be issued by the Commission and take all
     reasonable actions required to prevent the entry of such stop order or to
     remove it if entered at the earliest possible date.

           (c)  The Company will use its best efforts in cooperation with
     MascoTech and the Underwriters or agents, as the case may be, to (i)
     register or qualify the Registrable Securities for offer and sale under
     such other securities or blue sky laws of such jurisdictions in the United
     States as MascoTech reasonably requests and (ii) cause such Registrable
     Securities to be registered with or approved by such other governmental
     agencies or authorities as may be necessary by virtue of the business and
     operations of the Company and do any and all other acts and things that may
     be reasonably necessary or advisable to enable MascoTech to consummate the
     disposition of Registrable Securities; provided that the Company

                                       5
<PAGE>
 
     will not be required to (i) qualify generally to do business in any
     jurisdiction where it would not otherwise be required to qualify but for
     this paragraph (c), (ii) subject itself to taxation in any such
     jurisdiction or (iii) consent to general service of process in any such
     jurisdiction.

           (d)  The Company will immediately notify MascoTech, at any time when
     a prospectus relating to the sale of the Registrable Securities is required
     by law to be delivered in connection with sales by an Underwriter or
     dealer, of the occurrence of any event requiring the preparation of a
     supplement or amendment to such prospectus so that, as thereafter delivered
     to the purchasers of such Registrable Securities, such prospectus will not
     contain an untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading and shall promptly make available to MascoTech and to
     the Underwriters any such supplement or amendment. MascoTech agrees that,
     upon receipt of any notice from the Company of the occurrence of any event
     of the kind described in the preceding sentence, MascoTech will forthwith
     discontinue the offer and sale of Registrable Securities pursuant to the
     registration statement covering such Registrable Securities until receipt
     by MascoTech and the Underwriters of the copies of such supplemented or
     amended prospectus and, if so directed by the Company, MascoTech will
     deliver to the Company all copies, other than permanent file copies then in
     MascoTech's possession, of the most recent prospectus covering such
     Registrable Securities at the time of receipt of such notice.

           (e)  The Company will make available for inspection by MascoTech, any
     Underwriter participating in any disposition pursuant to such registration
     statement and any attorney, accountant or other professional retained by
     MascoTech or any such Underwriter (collectively, the "INSPECTORS"), all
     financial and other pertinent records, pertinent corporate documents and
     properties of the Company (collectively, the "RECORDS") as shall be
     reasonably necessary to enable them to exercise their due diligence
     responsibility, and cause the Company's officers, directors and employees
     to supply all information reasonably requested by any Inspectors in
     connection with such registration statement. Records which the Company
     determines, in good faith, to be confidential and which it notifies the
     Inspectors are confidential shall not be disclosed by the Inspectors unless
     (i) the disclosure of such Records is necessary to avoid or correct a
     misstatement or omission in such registration statement or (ii) the release
     of such Records is ordered pursuant to a subpoena or other order from a
     court of competent jurisdiction. MascoTech agrees that information obtained
     by it as a result of such inspections shall be deemed confidential and
     shall not be used by it for any purpose other than as described in this
     paragraph (e) unless and until such information is made generally available
     to the public. MascoTech further agrees that it will, upon learning that
     disclosure of such Records is sought in a court of competent jurisdiction,
     give notice to the Company and allow the Company, at its

                                       6
<PAGE>
 
     expense, to undertake appropriate action to prevent disclosure of the
     Records deemed confidential.

           (f)  The Company will comply with the 1933 Act and the rules and
     regulations of the Commission thereunder and the 1934 Act and the rules and
     regulations of the Commission thereunder so as to permit the completion of
     the distribution of the Registrable Securities pursuant to the registration
     statement in accordance with the intended method or methods of distribution
     contemplated in the prospectus relating thereto.

           (g)  Upon the request of MascoTech or the managing Underwriter or
     agent, as the case may be, or if required by the rules, regulations or
     instructions applicable to the registration form used by the Company, or by
     the 1933 Act or by any other rules and regulations thereunder in connection
     with the offering of Registrable Securities, the Company will prepare a
     prospectus supplement that complies with the 1933 Act and the rules and
     regulations of the Commission thereunder and that sets forth the aggregate
     amount of the Registrable Securities being sold, the name or names of any
     Underwriters or agents participating in the offering, the price at which
     the Registrable Securities are to be sold, any discounts, commissions or
     other items constituting compensation, and such other information as
     MascoTech or the managing Underwriter or agent, as the case may be, and the
     Company deem appropriate in connection with the offering of the Registrable
     Securities prior to its being used or filed with the Commission.

           (h)  Upon the request of the Company, MascoTech will promptly furnish
     in writing to the Company such information regarding the distribution of
     the Registrable Securities as may be legally required in connection with
     such registration as may be reasonably requested by the Company.

           (i)  The Company will enter into customary agreements (including an
     underwriting agreement in customary form) and take such other actions as
     are reasonably required in order to expedite or facilitate the disposition
     of such Registrable Securities.

           (j)  The Company will furnish to MascoTech and to each Underwriter a
     signed counterpart, addressed to MascoTech or such Underwriter, of (i) an
     opinion or opinions of counsel to the Company and (ii) a comfort letter or
     comfort letters from the Company's independent public accountants, each in
     customary form and covering such matters of the type customarily covered by
     opinions or comfort letters, as the case may be, as MascoTech or the
     managing Underwriter reasonably requests.

           (k)  The Company will make generally available to its security
     holders, as soon as reasonably practicable, an earnings statement covering
     a period of 12 months, beginning within three months after the effective
     date of the registration

                                       7
<PAGE>
 
     statement used to sell any Registrable Securities, which earnings statement
     shall satisfy the provisions of Section 11(a) of the 1933 Act and the rules
     and regulations of the Commission thereunder.

           (l)  The Company will use its best efforts to cause all such
     Registrable Securities to be listed on each securities exchange on which
     similar securities issued by the Company are then listed.

           (m)  MascoTech agrees to give the Company written notice of its
     intent to sell any Registrable Securities under the Shelf Registration
     Statement at least three business days prior to such sale. MascoTech agrees
     to complete and execute all questionnaires, powers of attorney,
     indemnities, underwriting agreements and other documents required under the
     terms of any underwritten offering in which MascoTech proposes to
     participate.

     3.2.  Registration Expenses.  In connection with the Shelf Registration
Statement and in connection with any Piggyback Registration (including the
Current Offering), the Company shall pay the following expenses incurred in
connection with such registration: (i) all registration and filing fees, (ii)
fees and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel in connection with blue sky
qualifications of the Registrable Securities), (iii) printing expenses, (iv)
fees and expenses incurred in connection with the listing of the Registrable
Securities, (v) fees and expenses of counsel and independent certified public
accountants for the Company and (vi) the reasonable fees and expenses of any
additional experts retained by the Company in connection with such registration.
MascoTech shall pay any underwriting fees, discounts or commissions and transfer
taxes attributable to the sale of Registrable Securities and any out-of-pocket
expenses of MascoTech.

                                  ARTICLE IV

                       INDEMNIFICATION AND CONTRIBUTION

     4.1.  Indemnification by the Company.  The Company agrees to indemnify and
hold harmless MascoTech, its officers and directors, and each Person, if any,
who controls MascoTech within the meaning of either Section 15 of the 1933
Act or Section 20 of the 1934 Act from and against any and all losses, claims,
damages and liabilities caused by any untrue statement or alleged untrue
statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities (as amended or supplemented if
the Company shall have furnished any amendments or supplements thereto) or any
preliminary prospectus, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information relating to
MascoTech or the plan of distribution furnished in writing to the Company by or
on behalf of MascoTech expressly 

                                       8
<PAGE>
 
for use therein; provided that the foregoing indemnity agreement with respect to
any (i) preliminary prospectus shall not inure to the benefit of MascoTech if a
copy of the most current prospectus at the time of the delivery of the
Registrable Securities was not provided to the purchaser and such current
prospectus would have cured the defect giving rise to such loss, claim, damage
or liability and was in fact previously furnished to the MascoTech and the
managing Underwriters, if any, and (ii) prospectus shall not inure to the
benefit of MascoTech if such untrue statement or alleged untrue statement,
omission or alleged omission is corrected in an amendment or supplement to the
prospectus and if having previously been furnished by or on behalf of the
Company with copies of the prospectus as so amended or supplemented, MascoTech
thereafter fails to deliver such prospectus as so amended or supplemented at
least one business day prior to the sale of Registrable Securities to the person
asserting such loss, claim, damage or liability who purchases such Registrable
Securities which are the subject thereof. The Company also agrees to indemnify
any Underwriters of the Registrable Securities, their officers and directors and
each person who controls such Underwriters on substantially the same basis as
that of the indemnification of MascoTech provided in this Section 4.1.

     4.2.  Indemnification by MascoTech.  MascoTech agrees to indemnify and hold
harmless the Company, its officers and directors, and each Person, if any, who
controls the Company within the meaning of either Section 15 of the 1933 Act or
Section 20 of the 1934 Act to the same extent as the foregoing indemnity from
the Company to MascoTech, but only with reference to information relating to
MascoTech or the plan of distribution furnished in writing by or on behalf of
MascoTech expressly for use in any registration statement or prospectus relating
to the Registrable Securities, or any amendment or supplement thereto, or any
preliminary prospectus.  MascoTech also agrees to indemnify and hold harmless
any Underwriters of the Registrable Securities, their officers and directors and
each person who controls such Underwriters on substantially the same basis as
that of the indemnification of the Company provided in this Section 4.2.

     4.3.  Conduct of Indemnification Proceedings.  In case any proceeding
(including any governmental investigation) shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to Section 4.1 or
Section 4.2, such Person (the "INDEMNIFIED PARTY") shall promptly notify the
Person against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in
writing and the Indemnifying Party, upon the request of the Indemnified Party,
shall assume the defense thereof, including the employment of counsel reasonably
satisfactory to such Indemnified Party and shall assume the payment of all fees
and expenses. In any such proceeding, any Indemnified Party shall have the right
to retain its own counsel, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the Indemnified Party and the Indemnifying Party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
Indemnifying Party shall not, in

                                       9
<PAGE>
 
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm of attorneys
(in addition to any local counsel) at any time for all such Indemnified Parties,
and that all such fees and expenses shall be reimbursed as they are incurred. In
the case of any such separate firm for the Indemnified Parties, such firm shall
be designated in writing by the Indemnified Parties. The Indemnifying Party
shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent, or if there be a final
judgment for the plaintiff, the Indemnifying Party shall indemnify and hold
harmless such Indemnified Parties from and against any loss or liability (to the
extent stated above) by reason of such settlement or judgment. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability arising out
of such proceeding.

     4.4.  Contribution.  To the extent the indemnification provided for in this
Article IV is unavailable to an Indemnified Party in respect of any losses,
claims, damages or liabilities referred to herein, then in lieu of such
indemnification (i) as between the Company and any other selling shareholders,
on the one hand, and MascoTech, on the other hand, the Company, such other
selling shareholders and MascoTech shall contribute to such aggregate losses,
liabilities, claims, damages and expenses in such proportion as is appropriate
to reflect the relative benefits received by the Company and any such selling
shareholders on the one hand and MascoTech on the other from the offering of the
Securities, or if such allocation is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits but also
the relative fault of the Company and any such selling shareholders, on the one
hand, and of MascoTech, on the other hand, in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations and (ii) as
between the Company, any other selling shareholders and MascoTech, on the one
hand, and the Underwriters or agents, on the other hand, the Company, such
selling shareholders, MascoTech and such Underwriters or agents shall contribute
to such aggregate losses, liabilities, claims, damages and expenses in such
proportion as is appropriate to reflect not only the relative benefits but also
the relative fault of the Company, any such selling shareholders and MascoTech,
on the one hand, and the Underwriters or agents, on the other hand, in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

     The relative benefits received by the Company, such selling shareholders
and MascoTech and the Underwriters or agents shall be deemed to be in the same
proportion as the total proceeds from the offering (net of underwriting
discounts and commissions but before deducting expenses) received by the
Company, such selling shareholders and MascoTech bear to the total underwriting
discounts and commissions received by the Underwriters or agents, in each case
as set forth in the prospectus. The relative fault of 

                                       10
<PAGE>
 
the Company, any other selling shareholders, MascoTech and the Underwriters or
agents shall be determined by reference to, among other things, whether any such
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by the
Company, such selling shareholders, MascoTech or such Underwriters or agents and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

     The Company and MascoTech agree that it would not be just and equitable if
contribution pursuant to this Section 4.4 were determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable
considerations referred to in the immediately preceding paragraph.  The amount
paid or payable by an Indemnified Party as a result of the losses, claims,
damages or liabilities referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Article IV, MascoTech shall not be required to contribute any
amount in excess of the amount by which the net proceeds of the offering (before
deducting expenses) received by MascoTech exceeds the amount of any damages
which MascoTech has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any Person who was not guilty of
such fraudulent misrepresentation.


                                   ARTICLE V

                        VOTING OF THE MASCOTECH SHARES


     5.1  Voting of the MascoTech Shares.   (a) MascoTech shall vote the
MascoTech Shares in the same manner as the Common Stock held by Onex is voted,
on the election of directors and on all other matters which are submitted to a
vote (or consent in lieu of voting) of the Company's stockholders, and for this
purpose, shall execute and deliver to Onex (or its designees) proxies to vote
the MascoTech Shares in the same manner as the Common Stock held by Onex is
voted.  Without limiting the generality of the foregoing, to the extent
permitted by law, MascoTech, by its execution of this Agreement, irrevocably
constitutes and appoints Onex or its designee MascoTech's proxy to vote all of
the MascoTech Shares at any meeting of stockholders of the Company or to give
consent in lieu of voting on any matter which is submitted for a vote or consent
to the stockholders, provided that the MascoTech Shares are voted or consent is
given with respect to such shares in the same manner as with respect to the
Common Stock held by Onex.  Notwithstanding anything to the contrary contained
in this Article V, the MascoTech Shares shall not, except with the express
consent of MascoTech be voted in favor of any resolution the effect of which
will be to change the MascoTech Shares or the Common Stock held by Onex or
convert or exchange the MascoTech Shares or the Common Stock held by Onex into
or for different securities unless in every such case the 

                                       11
<PAGE>
 
MascoTech Shares and the Common Stock held by Onex are thereby changed
identically or converted into or exchanged for the same type of securities in
proportion to their respective holdings of Common Stock in each case on terms
consistent with the rights and preferences set forth in the Company's
Certificate of Incorporation, as is reasonably determined by Onex.

     (b)  The voting agreement set forth in this Article V shall continue with
respect to each MascoTech Share until the earlier of:  (i) the date on which
MascoTech or any affiliate of MascoTech no longer owns such MascoTech Share,
(ii) the date on which such MascoTech Share ceases to be a "restricted security"
within the meaning of Rule 144 under the 1933 Act, or (iii) the tenth
anniversary of the date of this Agreement.


                                  ARTICLE VI

                                 MISCELLANEOUS


     6.1.  Rule 144.  The Company covenants that it will file any reports
required to be filed by it under the 1933 Act and the 1934 Act and that it will
take such further action as MascoTech may reasonably request to the extent
required from time to time to enable MascoTech to sell Registrable Securities
without registration under the 1933 Act within the limitation of the exemptions
provided by Rule 144 under the 1933 Act, as such Rule may be amended from time
to time, or any similar rule or regulation hereafter adopted by the Commission.
Upon the request of MascoTech, the Company will deliver to MascoTech a written
statement as to whether it has complied with such reporting requirements.

     6.2.  Transfer of Registration Rights.  None of the rights of MascoTech
under this Agreement shall be assignable by MascoTech without the prior written
consent of the Company.

provided shall be cumulative and not exclusive of any rights or remedies

         on May 31, 1996, and has not been registered under the 
         Securities Act of 1933, as amended (the "Act"), and may not 
         be sold or transferred in the absence of an effective

         registration thereunder.

                                PROMISSORY NOTE

May 31, 1996                                                        $5,000,000

          R.J. Tower Corporation, a Michigan corporation (the "Company"), hereby
promises to pay to the order of MascoTech, Inc. the principal amount of
$5,000,000, as adjusted pursuant to Section 2(a) below, in accordance with the
provisions of this Note.

          This Note is issued pursuant to the Stock Purchase Agreement, dated as
of May 31, 1996, by and between the Company and MascoTech, Inc. (the "Purchase
Agreement"), and this Note is the "Note" referred to in the Purchase Agreement.
Unless otherwise indicated herein, capitalized terms used in this Note have the
same meaning set forth in the Purchase Agreement.

          1.   Payment of Interest.  Interest on the unpaid principal amount of
this Note (as determined pursuant to Section 2(a) below) shall accrue at the
lower of (i) seven percent per annum (7%) or (ii) the highest rate permitted by
law, computed on the basis of a 360 day year for the actual number of days
elapsed. All accrued interest which has not theretofore been paid shall be paid
in full on the date on which payment on this Note is due in full. Interest on
overdue principal and, to the extent permitted by applicable law, on overdue
installments of interest, shall accrue at a rate per annum equal to the lower of
(i) nine percent per annum (9%) or (ii) the highest rate permitted by law.

          2.   Payment of Principal on Note.

          (a)  Schedule Maturity.  On the date on which a final determination is
made with respect to the Earnout Amount for the first Anniversary Period
following the Closing pursuant to Section 1.4 of the Purchase Agreement, the
Company shall pay in immediately available funds to the holder of this Note, to
the extent the following calculation yields a result greater than zero, the
principal amount of (A) $5,000,000 minus (B) the excess, if any, of (1) $29.5
million over (2) the Plant Profits for the first Anniversary Period following
the Closing.

          (b)  Prepayments.  The Company may not prepay all or any portion of
the outstanding principal amount of the Note, without the prior written consent
of the holder hereof.
<PAGE>
 
          3.   Events of Default.

          (a)  Definition.  For purposes of this Note, an Event of Default shall
be deemed to have occurred if:

               (i)    the Company fails to pay when due the full principal
     amount or interest under this Note; or

               (ii)   the Company makes an assignment for the benefit of
     creditors or admits in writing its inability to pay its debts generally as
     they become due; or an order, judgment or decree is entered adjudicating
     the Company bankrupt or insolvent; or any order for relief with respect to
     the Company is entered under the Federal Bankruptcy Code; or the company
     petitions or applies to any tribunal for the appointment of a custodian,
     trustee, receiver or liquidator of the Company, or of any substantial part
     of the assets of the company, or commences any proceeding (other than an
     proceeding for the voluntary liquidation and dissolution of any Subsidiary)
     relating to the Company under any bankruptcy, reorganization, arrangement,
     insolvency, readjustment of debt, dissolution or liquidation law of any
     jurisdiction; or any such petition or application is filed, or any such
     proceeding is commenced, against the Company and either (A) the Company by
     any act indicates its approval thereof, consent thereto or acquiescence
     therein or (B) such petition, application or proceeding is not dismissed
     within 60 days. "Subsidiary" means any corporation of which the shares of
     outstanding capital stock possessing the voting power (under ordinary
     circumstances) in electing the board of directors are, at the time as of
     which any determination is being made, owned by the Company, either
     directly or indirectly through Subsidiaries.

          (b) Consequences of Events of Default.

               (i)    If an Event of Default of the type described in
     subparagraph 3(a)(ii) has occurred, the aggregate principal amount of this
     Note (together with all accrued but unpaid interest thereon) shall become
     immediately due and payable without any action on the part of the holder of
     this Note, and the Company shall immediately pay to the holder of this Note
     all amounts due and payable with respect to this Note.

               (ii)   If an Event of Default of the type described in
     subparagraph 3(a)(i) has occurred, the holder of this Note may declare all
     or any portion of the outstanding principal amount of this Note (together
     with all accrued but unpaid interest thereon) due and payable.

               (iii)  The holder of this Note shall also have any other rights
     which such holder may have been afforded under any contract or agreement at
     any time and any other rights which such holder may have pursuant to
     applicable law.

     reasonable attorneys' fees.

     and demand and notice of protest and demand, dishonor and nonpayment of

time owed on this Note has been paid in full, this Note shall be surrendered to
the Company for cancellation and shall not be reissued.

MascoTech, Inc. without the prior written consent of the Company.

          7.   Setoff.  This Note will be subject to setoff only to the extent

     The security represented by this certificate was originally issued on May

     amended (the "Securities Act"),  and may not be transferred without

                            STOCK PURCHASE WARRANT
                            ----------------------


Date of Issuance:  May 31, 1996                            Certificate No. W-1


FOR VALUE RECEIVED, Tower Automotive, Inc., a Delaware corporation (the
"Company"), hereby grants to MascoTech, Inc. (the "Registered Holder") the right
to purchase from the Company 200,000 fully paid and non-assessable shares of the
Company's common stock, par value $0.01 per share ("Common Stock") at a price
per share of $18.00 (as adjusted from time to time in accordance herewith, the
"Exercise Price").  This Warrant is issued pursuant to the terms of the Stock
Purchase Agreement, dated as of May 31, 1996 (the "Purchase Agreement"), between
the Company and the Registered Holder.  Certain capitalized terms used herein
are defined in Section 3 hereof.  The amount and kind of securities obtainable
pursuant to the rights granted hereunder and the purchase price for such
securities are subject to adjustment pursuant to the provisions contained in
this Warrant.

          For income tax purposes, the value of this Warrant on the date hereof
is $2.0 million.

          This Warrant is subject to the following provisions:

          Section 1.  Exercise of Warrant.

          1A.  Exercise Period.  The Registered Holder may exercise, in whole or
in part (but not as to a fractional share of Common Stock), the purchase rights
represented by this Warrant at any time and from time to time after the Date of
Issuance to and including May 31, 2000 or, if such day is not a business day,
then on the next succeeding business day (the "Exercise Period").

          1B.  Exercise Procedure.

          (i) This Warrant shall be deemed to have been exercised when the
Company has received all of the following items (the "Exercise Time"):
<PAGE>
 
          (a)  a completed Exercise Agreement, as described in paragraph 1C
below, executed by the Person exercising all or part of the purchase rights
represented by this Warrant (the "Purchaser");

          (b)  this Warrant; and

          (c)  a wire transfer of immediately available funds to the Company in
an amount equal to the product of the Exercise Price multiplied by the number of
shares of Common Stock being purchased upon such exercise (the "Aggregate
Exercise Price").

          (ii) Certificates for shares of Common Stock purchased upon exercise
of this Warrant shall be delivered by the Company to the Purchaser within five
business days after the date of the Exercise Time. Unless this Warrant has
expired or all of the purchase rights represented hereby have been exercised,
the Company shall prepare a new Warrant, substantially identical hereto,
representing the rights formerly represented by this Warrant which have not
expired or been exercised and shall, within such five-day period, deliver such
new Warrant to the Person designated for delivery in the Exercise Agreement.

          (iii) The Common Stock issuable upon the exercise of this Warrant
shall be deemed to have been issued to the Purchaser at the Exercise Time, and
the Purchaser shall be deemed for all purposes to have become the record holder
of such Common Stock at the Exercise Time notwithstanding that the stock
transfer books of the Company shall then be closed or that certificates
representing such Warrant Shares shall not then be actually delivered to the
Holder.

          (iv) The issuance of certificates for shares of Common Stock upon
exercise of this Warrant shall be made without charge to the Registered Holder
or the Purchaser for any issuance tax in respect thereof or other cost incurred
by the Company in connection with such exercise and the related issuance of
shares of Common Stock. Each share of Common Stock issuable upon exercise of
this Warrant shall, upon payment of the Exercise Price therefor, be validly
issued, fully paid and nonassessable and free from all liens and charges with
respect to the issuance thereof.

          (v) The Company shall not close its books against the transfer of this
Warrant or of any share of Common Stock issued or issuable upon the exercise of
this Warrant in any manner which interferes with the timely exercise of this
Warrant. The Company shall from time to time take all such action as may be
necessary to assure that the par value per share of the unissued Common Stock
acquirable upon exercise of this Warrant is at all times equal to or less than
the Exercise Price then in effect.

          (vi) Notwithstanding any other provision hereof, if an exercise of any
portion of this Warrant is to be made in connection with a registered public
offering or the sale of the Company, the exercise of any portion of this Warrant
may, at the election of the holder hereof, be conditioned upon the consummation
of the public offering or sale of the Company in which case such exercise shall
not be deemed to be effective until the consummation of such transaction.

          (vii) The Company shall at all times reserve and keep available out of
its authorized but unissued shares of Common Stock solely for the purpose of
issuance upon the exercise of the

                                       2
<PAGE>
 
Warrants, such number of shares of Common Stock issuable upon the exercise of
all outstanding Warrants. All shares of Common Stock which are so issuable
shall, when issued, be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges. The Company shall take all such actions
as may be necessary to assure that all such shares of Common Stock may be so
issued without violation of any applicable law or governmental regulation or any
requirements of any domestic securities exchange upon which shares of Common may
be listed (except for official notice of issuance which shall be immediately
delivered by the Company upon each such issuance). The Company shall not take
any action which would cause the number of authorized but unissued shares of
Common Stock to be less than the number of such shares required to be reserved
hereunder for issuance upon exercise of the Warrant.

          (viii) Upon any exercise of this Warrant, the Company may require
customary investment representations from the Registered Holder and the
Purchaser to assure that the issuance of the Common Stock hereunder shall not
require registration or qualification under the Securities Act or any state
securities laws.

          1C.  Exercise Agreement.  Upon any exercise of this Warrant, the
Exercise Agreement shall be substantially in the form set forth in Exhibit I
hereto, except that if the shares of Common Stock are not to be issued in the
name of the Person in whose name this Warrant is registered, the Exercise
Agreement shall also state the name of the Person to whom the certificates for
the shares of Common Stock are to be issued, and if the number of shares of
Common Stock to be issued does not include all the shares of Common Stock
purchasable hereunder, it shall also state the name of the Person to whom a new
Warrant for the unexercised portion of the rights hereunder is to be delivered.
Such Exercise Agreement shall be dated the actual date of execution thereof.

          1D.  Fractional Shares.  If a fractional share of Common Stock would,
but for the provisions of paragraph 1A, be issuable upon exercise of the rights
represented by this Warrant, the Company shall, within five business days after
the date of the Exercise Time, deliver to the Purchaser a check payable to the
Purchaser in lieu of such fractional share in an amount equal to the difference
between the Market Price of such fractional share as of the date of the Exercise
Time and the Exercise Price of such fractional share.

          Section 2.  Adjustment of Exercise Price and Number of Shares.  In
order to prevent dilution of the rights granted under this Warrant, the Exercise
Price shall be subject to adjustment from time to time as provided in this
Section 2, and the number of shares of Common Stock obtainable upon exercise of
this Warrant shall be subject to adjustment from time to time as provided in
this Section 2.

          2A.  (i)  Subdivision or Combination of Common Stock.  If the Company
at any time after the date hereof (a) declares a dividend or makes a
distribution on its shares of capital stock payable in Common Stock or (b)
subdivides (by any stock split, stock dividend or recapitalization) its
outstanding shares of Common Stock into a greater number of shares, the Exercise
Price in effect immediately prior to such subdivision shall be proportionately
reduced and the number of shares of Common Stock obtainable upon exercise of
this Warrant shall be proportionately increased. If the Company at any time
combines (by reverse stock split or recapitalization) its outstanding shares of
Common Stock into a smaller number of shares, the 

                                       3
<PAGE>
 
Exercise Price in effect immediately prior to such combination shall be
proportionately increased and the number of shares of Common Stock obtainable
upon exercise of this Warrant shall be proportionately decreased.

          (ii) Sale of Common Stock at Less than Market Price. In case the
Company shall issue or sell any Common Stock (other than Common Stock issued (a)
upon exercise of the Warrants, (b) pursuant to the Company's Independent
Director Stock Option Plan, the 1994 Key Employee Stock Option Plan or pursuant
to any similar Common Stock related employee or director compensation plan or
agreement of the Company approved by the Company's board of directors (the
"Board of Directors"), (c) upon exercise, exchange or conversion of any security
either issued on or prior to the date hereof or the issuance of which caused an
adjustment hereunder, or (d) pursuant to any registered public offering of
Common Stock) without consideration or for a consideration per share less than
95% of the Market Price (as defined below) per share of Common Stock, the
Exercise Price to be in effect after such issuance or sale shall be determined
by multiplying the Exercise Price in effect immediately prior to such issuance
or sale by a fraction, the numerator of which shall be the sum of (x) the number
of shares of Common Stock outstanding immediately prior to the time of such
issuance or sale multiplied by the Market Price per share of Common Stock
immediately prior to such issuance or sale and (y) the aggregate consideration,
if any, to be received by the Company upon such issuance or sale, and the
denominator of which shall be the product of the aggregate number of shares of
Common Stock outstanding immediately after such issuance or sale and the Market
Price per share of Common Stock immediately prior to such issuance or sale. In
case any portion of the consideration to be received by the Company shall be in
a form other than cash, the fair market value of such noncash consideration
shall be utilized in the foregoing computation. Such fair market value shall be
determined by the Board of Directors of the Company. The Registered Holders
shall be notified promptly of any consideration other than cash to be received
by the Company and furnished with a description of the consideration and the
fair market value thereof, as determined by the Board of Directors.

          (iii) Setting Record Date for Issuance of Certain Rights, Options or
Warrants.  In case the Company shall fix a record date for the issuance of
rights, options or warrants to the holders of its Common Stock or other
securities entitling such holders to subscribe for or purchase for a period
expiring within 60 days of such record date shares of Common Stock (or
securities convertible into shares of Common Stock) at a price per share of
Common Stock (or having a conversion price per share of Common Stock, if a
security convertible into shares of Common Stock) less than 95% of the Market
Price per share of Common Stock on such record date, the maximum number of
shares of Common Stock issuable upon exercise of such rights, options or
warrants (or conversion of such convertible securities) shall be deemed to have
been issued and outstanding as of such record date and the Exercise Price shall
be adjusted pursuant to paragraph 2A(ii) hereof, as though such maximum number
of shares of Common Stock had been so issued for an aggregate consideration
payable by the holders of such rights, options, warrants or convertible
securities prior to their receipt of such shares of Common Stock. In case any
portion of such consideration shall be in a form other than cash, the fair
market value of such noncash consideration shall be determined as set forth in
paragraph 2A(ii) hereof. Such adjustment shall be made successively whenever
such record date is fixed; and in the event that such rights, options or
warrants are not so issued or expire unexercised, or in the event of a change in
the number of shares of Common Stock to which the holders of such rights,
options or warrants are entitled (other than pursuant to adjustment provisions

                                       4
<PAGE>
 
therein comparable to those contained in this paragraph), the Exercise Price
shall again be adjusted to be the Exercise Price which would then be in effect
if such record date had not been fixed, in the former event, or the Exercise
Price which would then be in effect if such holder had initially been entitled
to such changed number of shares of Common Stock, in the latter event.

          (iv) Issuance of Certain Rights, Options or Warrants.  In case the
Company shall issue rights, options (other than options issued pursuant to a
plan or agreement described in clause (b) of paragraph (ii)) or warrants
entitling the holders thereof to subscribe for or purchase Common Stock (or
securities convertible into shares of Common Stock) or shall issue convertible
securities, and the price per share of Common Stock of such rights, options,
warrants or convertible securities (including the aggregate amount of additional
consideration payable upon exercise, conversion or exchange of such rights,
options, warrants or convertible securities) is less than 95% of the Market
Price per share of Common Stock, the maximum number of shares of Common Stock
issuable upon exercise of such rights, options or warrants or upon conversion of
such convertible securities shall be deemed to have been issued and outstanding
as of the date of such sale or issuance, and the Exercise Price shall be
adjusted pursuant to paragraph 2A(ii) hereof as though such maximum number of
shares of Common Stock had been so issued for an aggregate consideration equal
to the aggregate consideration paid for such rights, options, warrants or
convertible securities and the aggregate consideration payable by the holders of
such rights, options, warrants or convertible securities prior to their receipt
of such shares of Common Stock. In case any portion of such consideration shall
be in a form other than cash, the fair market value of such noncash
consideration shall be determined as set forth in paragraph 2A(ii) hereof. Such
adjustment shall be made successively whenever such rights, options, warrants or
convertible securities are issued; and in the event that such rights, options or
warrants expire unexercised, or in the event of a change in the number of shares
of Common Stock to which the holders of such rights, options, warrants or
convertible securities are entitled (other than pursuant to adjustment
provisions therein comparable to those contained in this paragraph (iv)), the
Exercise Price shall again be adjusted to be the Exercise Price which would then
be in effect if such rights, options, warrants or convertible securities had not
been issued, in the former event, or the Exercise Price which would then be in
effect if such holders had initially be entitled to such changed number of
shares of Common Stock, in the latter event. No adjustment of the Exercise Price
shall be made pursuant to this paragraph to the extent that the Exercise Price
shall have been adjusted pursuant to paragraph 2A(iii) upon the setting of any
record date relating to such rights, options, warrants or convertible securities
and such adjustment fully reflects the number of shares of Common Stock to which
the holders of such rights, options, warrants or convertible securities are
entitled and the price payable therefor.

          (v) Certain Distributions.  In case the Company shall fix a record
date for the making of a distribution to holders of Common Stock (including any
such distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, assets or
other property (other than cash dividends or distributions and dividends payable
in Common Stock or rights, options or warrants referred to in, and for which an
adjustment is made pursuant to, paragraph 2A(iii) hereof), the Exercise Price to
be in effect after such record date shall be determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the Market Price per share of Common Stock on
such record date, less the fair market value (determined as set forth in
paragraph 2A(ii) hereof) of the portion of the assets, other property or
evidence of indebtedness so to be

                                       5
<PAGE>
 
distributed which is applicable to one share of Common Stock, and the
denominator of which shall be such Market Price per share of Common Stock. Such
adjustments shall be made successively whenever such a record date is fixed; and
in the event that such distribution is not so made, the Exercise Price shall
again be adjusted to be the Exercise Price which would then be in effect if such
record date had not been fixed.

          (vi) Extraordinary Dividends.  In case in any fiscal quarter (a) the
Company shall distribute to all holders of shares of Common Stock any cash
dividend or distribution or (b) the Company or any of its subsidiaries shall
purchase Common Stock pursuant to a tender offer for a purchase price per share
greater than 105% of the Market Price per share of Common Stock on the date of
purchase, and during such fiscal quarter the sum of (x) all such cash dividends
or distributions, plus (y) the aggregate amount by which the fair market value
(determined as set forth in paragraph 2A(ii) hereof) of the consideration paid
in purchasing all such shares of Common Stock exceeds the Market Price per share
of Common Stock on the date of such purchase multiplied by the number of shares
of Common Stock so purchased, shall exceed the greater of (x) 2.5% of the Market
Price per share of Common Stock multiplied by the number of shares of Common
Stock outstanding at the earlier of the record date for the latest such cash
dividend or distribution or tender offer or the date at which the Company shall
have publicly announced such dividend or distribution or tender offer and (y)
the amount per share of Common Stock of the next preceding quarterly cash
dividend not constituting an Extraordinary Dividend multiplied by the number of
shares of Common Stock outstanding at the record date for such quarterly cash
dividend, then the Exercise Price shall be adjusted on the date of such dividend
or distribution, or the termination of such tender offer, to a price determined
by multiplying the Exercise Price in effect immediately prior to the earlier of
such dates by a fraction, of which the numerator shall be the Market Price per
share of Common Stock on the earlier of such dates less the fair market value
(determined as set forth in paragraph 2A(ii) hereof) of the portion of such
distribution or excess amount which is applicable to one share of Common Stock
and of which the denominator shall be such Market Price per share of Common
Stock on the earlier of such dates.

          2B.  Reorganization, Reclassification, Consolidation, Merger or Sale.
Any recapitalization, reorganization, reclassification, consolidation, merger,
sale of all or substantially all of the Company's assets or other transaction,
in each case which is effected in such a way that the holders of Common Stock
are entitled to receive (either directly or upon subsequent liquidation) stock,
securities or assets with respect to or in exchange for Common Stock is referred
to herein as "Organic Change." Prior to the consummation of any Organic Change,
the Company shall make appropriate provision to insure that each of the
Registered Holders of the Warrants shall thereafter have the right to acquire
and receive, in lieu of or addition to (as the case may be) the shares of Common
Stock immediately theretofore acquirable and receivable upon the exercise of
this Warrant, such shares of stock, securities or assets (including cash) as may
be issued or payable with respect to or in exchange for the number of shares of
Common Stock immediately theretofore acquirable and receivable upon exercise of
this Warrant had such Organic Change not taken place. The Company shall not
effect any such consolidation, merger or sale, unless prior to the consummation
thereof, the successor entity (if other than the Company) resulting from
consolidation or merger or the entity purchasing such assets assumes by written
instrument, the obligation to deliver to each such holder such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to acquire.

          2C.  Notices.

          (i) Immediately upon any adjustment of the Exercise Price, the Company
shall give written notice thereof to the Registered Holder, setting forth in
reasonable detail and certifying the calculation of such adjustment.

          (ii) The Company shall also give written notice to the Registered
Holders at least 20 days prior to the date on which any Organic Change,
dissolution or liquidation shall take place.

          2D.  Adjustments to Number of Shares.  Upon each adjustment of the
Exercise Price as a result of the calculations made in paragraphs (ii), (iii),
(iv), (v) and (vi) of Section 2A, the number of shares for which this Warrant is
exercisable immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Exercise Price, that number of
shares of Common Stock obtained by (a) multiplying the number of shares covered
by this Warrant immediately prior to adjustment by the Exercise Price in effect
immediately prior to such adjustment of the Exercise Price and (b) dividing the
product so obtained by the Exercise Price in effect immediately after such
adjustment of the Exercise Price.

          2E.  Adjustments to Other Capital Stock.  In the event that, at the
time as a result of the provisions of this Section 2, the holder of this Warrant
upon subsequent exercise shall become entitled to receive any shares of capital
stock other than Common Stock, the number of such other shares so receivable
upon exercise of this Warrant shall thereafter be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions contained herein.

          Section 3.  Definitions.  The following terms have meanings set forth
below:

          "Market Price" means as to any security the average of the closing
prices of such security's sales on all domestic securities exchanges on which
such security may at the time be listed, or, if there have been no sales on any
such exchange on any day, the average of the highest bid and lowest asked prices
on all such exchanges at the end of such day, or, if on any day such security is
not so listed, the average of the representative bid and asked prices quoted in
the NASDAQ System as of 4:00 P.M., New York time, on such day, or, if on any day
such security is not quoted in the NASDAQ System, the average of the highest bid
and lowest asked prices on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of 30 days
consisting of the day as of which "Market Price" is being determined and the 29
consecutive business days prior to such day; provided that if such security is
listed on any domestic securities exchange the term "business days" as used in
this sentence means business days on which such exchange is open for trading. If
at any time such security is not listed on any domestic securities exchange or
quoted in the NASDAQ System or the domestic over-the-counter market, the "Market
Price" shall be the fair value thereof determined jointly by the Company and the
Registered Holder; provided that if such parties are unable to reach agreement
within a reasonable period of time, such fair value shall be determined by an
appraiser jointly selected by the Company and the Registered Holder. The
determination of such appraiser shall be final and binding on the Company and
the Registered Holder, and the fees and expenses of such appraiser shall be paid
by the Company.

                                       7

organization and a government or any department or agency thereof.

          Section 4.  No Voting Rights; Limitations of Liability.  This Warrant
shall not entitle the holder hereof to any voting rights or other rights as a
stockholder of the Company. No provision hereof, in the absence of affirmative
action by the Registered Holder to purchase Common Stock, and no enumeration
herein of the rights or privileges of the Registered Holder shall give rise to
any liability of such holder for the Exercise Price of Common Stock acquirable
by exercise hereof or as a stockholder of the Company.

          Section 5.  Warrant Transferable.  This Warrant shall not be sold,
assigned or otherwise transferred, in whole or in part, without the prior
written consent of the Company.

          Section 6.  Legend.  The Common Stock issuable under this Warrant

     amended (the "Securities Act"),  and may not be transferred without
     registration under the Securities Act or an exemption from registration
     thereunder.  Prior to any sales or transfers of this certificate, except
     pursuant to an effective registration statement under the Securities Act,
     the holder hereof shall deliver to the issuer hereof an opinion of counsel,
     satisfactory to the issuer, that such registration is not required.

          Section 7.  Warrant Exchangeable for Different Denominations.  This
Warrant is exchangeable, upon the surrender hereof by the Registered Holder at
the principal office of the Company, for new Warrants of like tenor representing
in the aggregate the purchase rights hereunder, and each of such new Warrants
shall represent such portion of such rights as is designated by the Registered
Holder at the time of such surrender. The date the Company initially issues this
Warrant shall be deemed to be the "Date of Issuance" hereof regardless of the
number of times new certificates representing the unexpired and unexercised
rights formerly represented by this Warrant shall be issued. All Warrants
representing portions of the rights hereunder are referred to herein as the
"Warrants."

          Section 8.  Replacement.  Upon receipt of evidence reasonably
satisfactory to the Company (an affidavit of the Registered Holder shall be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing this Warrant, and in the case of any such loss, theft
or destruction, upon receipt of indemnity reasonably satisfactory to the Company
(provided that if the holder is a financial institution or other institutional
investor its own agreement shall be satisfactory), or, in the case of any such
mutilation upon surrender of such certificate, the Company shall (at its
expense) execute and deliver in lieu of such certificate a new certificate of
like kind representing the same rights represented by such lost, stolen,
destroyed or mutilated certificate and dated the date of such lost, stolen,
destroyed or mutilated certificate.

FOR IMMEDIATE RELEASE
- ---------------------
TOWER AUTOMOTIVE, INC.
COMPLETES ACQUISITION OF MASCOTECH STAMPING
TECHNOLOGIES, INC.

     MINNEAPOLIS, MAY 31, 1996 -- Tower Automotive, Inc. (NASDAQ:TWER), today
announced that it has completed the previously announced acquisition of all of
the outstanding common stock of MascoTech Stamping Technologies, Inc. (MSTI), a
wholly owned subsidiary of MascoTech, Inc. (NYSE:MSX).

     MSTI manufactures and assembles chassis and suspension components for the
automotive industry in three facilities in Ohio and Indiana, and had 1995
revenues of approximately $153 million. Principal customers are Ford and
Chrysler.

     The purchase price consisted of $55 million in cash, a $5 million note,
785,000 shares of Tower Automotive common stock and warrants to acquire 200,000
shares of Tower Automotive common stock at an exercise price of $18 per share.
MascoTech will receive additional consideration of up to $25 million, if this
business achieves certain operating results over the next three years. The cash
portion of the purchase price was financed with the proceeds of a $65 million
private placement of senior notes.

     In a separate transaction, Tower Automotive has agreed to resource certain 
production from a non-acquired MSTI facility to existing Tower Automotive 
facilities. In addition, Tower Automotive will acquire selected inventory, 
tooling and equipment related to such production.

     Tower Automotive, Inc., is a leading designer and manufacturer of high
quality, engineered metal stampings and assemblies for North American light
vehicle manufacturers including Ford, Chrysler, Honda, Mazda, Toyota, Nissan and
General Motors. The Company's products include engineered mechanical parts, such
as hood and deck lid hinges and brake components, large structural stampings and
assemblies, such as body pillars, floor pan components and major housing
assemblies, and chassis and suspension components. The Company has operating
headquarters in Grand Rapids, Michigan and a corporate office in Minneapolis,
Minnesota.
