         This Form 8-K/A is being filed to amend the Form 8-K filed on February
25, 2003 to include the financial statements and pro forma financial information
referred to in Item 7 below relating to our acquisition of all of the
outstanding capital stock of Highland Group Corporation. At the time of the
filing on the Form 8-K, it was impractical for us to provide the financial and
pro forma information.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On February 21, 2003, TriMas Corporation (the "Company") announced its
acquisition of Highland Group Corporation ("Highland") pursuant to a Purchase
Agreement (the "Purchase Agreement") dated as of February 21, 2003, by and among
TriMas Company LLC, a subsidiary of the Company, the shareholders and option
holders of Highland (the "Sellers") and FNL Management Corp. as Sellers'
Representative.

         The consideration for the acquisition was approximately $70.5 million,
plus the amount of certain tax benefits, in cash. The purchase price is subject
to adjustment based upon actual working capital and taxes owed at closing. The
purchase price was financed through drawings on the Company's revolving credit
facility and cash on hand, as well as an equity investment by Heartland
Industrial Partners, L.P., and its affiliates. Since January 1, 2003, Heartland
has made approximately $30.0 million of equity investments in the Company.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS.

To the Shareholders
HIGHLAND GROUP CORPORATION

         We have audited the accompanying balance sheets of Highland Group
Corporation as of December 31, 2002 and 2001, and the related statements of
operations and retained earnings, and cash flows for the years ended December
31, 2002, 2001 and 2000. 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 auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Highland Group
Corporation as of December 31, 2002 and 2001, and the results of its operations
and its cash flows for the years ended December 31, 2002, 2001 and 2000 in
conformity with accounting principles generally accepted in the United States of
America.

         As discussed in Note 12 to the financial statements, the Company
adopted the provisions of Statement of Financial Accounting Standards No. 142,
"Goodwill and Other Intangible Assets" effective January 1, 2002.

Receivables are stated at the amount management expects to collect from
outstanding balances. Management provides for probable uncollectible amounts

outstanding after management has used reasonable collection efforts are written
off through a charge to the valuation allowance and a credit to trade accounts
receivable.

Debt issuance costs are amortized over the term of the related contract.
Amortization charged to operations for 2002, 2001 and 2000 was $50,000 each
year.

Stock option plan
- -----------------

The Company has a stock-based employee compensation plan, which is described
more fully in Note 9. The Company accounts for this plan under the recognition
and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued
to Employees," and related interpretations. No stock-based employee compensation
cost is reflected in net income, as all options granted under this plan had an
exercise price equal to the market value of the underlying stock on the date of
grant. The following table illustrates the effect on net income and earnings per
share if the Company had applied the fair value recognition provisions of FASB
Statement No. 123, "Accounting for Stock-Based Compensation," to stock-based
employee compensation.

NOTE 2 - USE OF ESTIMATES

In preparing financial statements in conformity with accounting principles
generally accepted in the United States of America, management makes estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements, as well as the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

NOTE 3 - REVOLVING CREDIT LINE

The Company has a revolving line of credit agreement with a commercial bank
which allows for maximum borrowings of $10,000,000. Interest is payable monthly
at a fluctuating rate based on the prime rate plus a margin amount. The margin
amount can range from .5% to 1.0% based upon certain financial ratios of the
Company. The Company may also elect a fixed interest rate for a specified period
of time, based on the applicable LIBOR rate and margin amount. The margin amount
for LIBOR loans is either 2.75% or 3.25%, based upon certain financial ratios of
the Company. The interest rate at December 31, 2002 is 4.75%. The loan is
secured by eligible accounts receivable, inventories, equipment and a first
mortgage on the Company's real property. Amounts borrowed under this agreement
totaled $1,531,061 and $1,012,792 at December 31, 2002 and 2001, respectively.

The Company is also required to pay a commitment fee to the bank on the unused
portion of the credit line, at an annual rate of .375%.

The Company's cash management arrangement with its commercial bank provides
automatic coverage of overdrafts up to its credit limit.

NOTE 9 - STOCK OPTION PLAN

Effective February 24, 1999 the Company adopted the Highland Group Corporation
1999 Key Employees Stock Option Plan. Effective August 7, 2001 the plan was
amended, restated and renamed the Highland Group Corporation Management Stock
Option Plan. The plan allows for options to be granted to Key employees as well
as outside directors of the Company. Options granted under this plan are
nonqualified stock options. Options may be issued for an aggregate of 64 shares
under this plan. For Key employees options vest over a two-year period from the
grant date, with 50% vesting after one year. For outside directors, options are
50% vested as of the grant date, 25% as of January 10, 2002 and the remaining
25% on January 10, 2003. The options expire on the tenth anniversary of the
effective date.

Options for a total of 51.24 shares have been granted, or approximately 5% of
the equity value of the Company.

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APBO No. 25), and related
interpretations, in accounting for this stock option plan. The company has
elected this treatment because, as discussed below, the alternative fair value
accounting provided for under Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" (SFAS No. 123), requires the use
of highly subjective assumptions in option valuation models. Under APBO No. 25,
no compensation expense has been recognized on the financial statements because
the exercise price of the Company's stock options is not less than the fair
market value of the shares at the grant date.

Pro forma information regarding net income, determined as if the Company had
adopted SFAS No. 123, is required by that statement, and is disclosed in Note 1
of these statements. The fair value for these options was estimated at the grant
date using the Black-Scholes option pricing model with the following assumptions
for all options granted: a risk-free interest rate of 4.89%; an expected life of
the options of five years for 1999 options; four years for 2000 options; two
years for 2002 options; no expected dividend yield; and no volatility factor.

NOTE 10 - INCOME TAXES

Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. The deferred tax benefit is comprised of allowance for doubtful accounts,
depreciation, amortization of goodwill, and various expense accruals.

The provision for income tax consists of the following:

NOTE 11 - MAJOR CUSTOMERS AND SUPPLIERS

Sales to one customer aggregated 44% in 2002. Sales to the Company's top three
customers aggregated 63% and 57% in 2001 and 2000. The Company made
approximately 48% of its purchases from two suppliers in each of 2002 and 2001
and this purchases amount was 49% in 2000. The Company grants credit to
customers, many of whom are major retail chains.


NOTE 12 - INTANGIBLE ASSETS

Effective January 2002, the Company adopted Statement of Financial Accounting
Standards No. 142, "Goodwill and Other Intangible Assets" (SFAS No. 142), which
provides that Goodwill shall no longer be amortized. Instead, Goodwill is to be
tested for impairment on an annual basis. The effect of this standard is that
the Company will no longer recognize amortization expense on its books for
Goodwill. If Goodwill were determined to be impaired, a charge to current
operation would be made in the year of impairment. The Company completed its
transitional goodwill impairment assessment and its annual impairment assessment
with no adjustment to the carrying value of its goodwill. Goodwill continues to
be amortized for tax purposes. The Company has a patent that is being amortized
over a 15-year period on a straight-line basis. Aggregate intangible
amortization expense was $21,292, $927,191 and $927,191 in 2002, 2001 and 2000,
respectively.

                                  (IN MILLIONS)


Prior to the acquisition of Highland, the Company acquired all of the capital
stock of HammerBlow Acquisition Corp. ("HammerBlow") from 2000 Riverside Capital
Appreciation Fund, L.P., and other stockholders of HammerBlow on January 30,
2003. The Company is not required under Regulation S-X to provide pro forma
financial information related to our acquisition of all of the capital stock of
HammerBlow, however, we have elected to do so in connection with the acquisition
of Highland.

The total consideration paid for HammerBlow was $142.3 million (including our
previous investment of $9.0 million), subject to a trade working capital
adjustment pursuant to the purchase agreement. Of this amount, $7.2 million net,
of the purchase price is deferred, payable in January of 2004. The purchase
price was financed through drawings on the Company's revolving credit facility
and cash on hand, as well as an equity investment by Heartland and its
affiliates.

The unaudited pro forma combined balance sheet as of December 31, 2002
("Unaudited Pro Forma Combined Balance Sheet") gives pro forma effect to the
acquisitions of Highland Group Corporation ("Highland") and HammerBlow
Acquisition Corporation ("HammerBlow") as if they had occurred on December 31,
2002. The acquisitions of Highland and HammerBlow will be accounted for by the
purchase method of accounting pursuant to which the purchase price is allocated
among the acquired tangible and intangible assets and assumed liabilities in
accordance with estimates of their fair values at the date of acquisition. The
pro forma adjustments include the Company's preliminary determination of
purchase accounting adjustments required and are based upon available
information and certain assumptions that the Company believes to be reasonable
under the circumstances. Consequently, the amounts reflected in the Unaudited
Pro Forma Combined Balance Sheet are subject to change and the final values may
differ from the amounts reflected herein. However, the Company does not expect
that differences between the preliminary and final purchase price allocation
will have a material impact on the Company's financial position. The Unaudited
Pro Forma Combined Balance Sheet does not purport to be indicative of the
financial position of the Company had such transactions actually been completed
as of the assumed dates and for the periods presented, or which may result in
the future.

The unaudited pro forma combined statement of operations for the year ended
December 31, 2002 ("Unaudited Pro Forma Combined Statement of Operations") gives
pro forma effect to the acquisitions of Highland and HammerBlow as if they had
occurred on January 1, 2002. The Unaudited Pro Forma Combined Statement of
Operations may not be indicative of the results of operations of the Company had
such transactions actually been completed as of the assumed dates, or which may
occur in the future.

The unaudited pro forma financial information also includes adjustments needed
to give pro forma effect to the common stock issuance and related financing
transactions that occurred on June 6, 2002 between the Company, Metaldyne
Corporation and Heartland Industrial Partners ("Heartland") pursuant to a stock
purchase agreement. To effect the transactions contemplated by the stock
purchase agreement, the Company entered into a senior credit facility consisting
of a $150 million revolving credit facility, a $260 million term loan facility
and $125 million receivables securitization facility and issued senior
subordinated debentures with a face value of $352.8 million. In addition, on
December 10, 2002 the Company issued an additional $85.0 of senior subordinated
debentures. The bonds were issued to obtain cash to repurchase approximately
$20.0 million of TriMas common stock owned by Metaldyne, to fund potential
acquisitions, for debt repayment and for other general corporate purposes.

          NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS
                                  (IN MILLIONS)


For purposes of the Unaudited Pro Forma Combined Statement of Operations, the
results of TriMas for the twelve months ended December 31, 2002 have been
combined with the results of Highland for the twelve months ended December 31,
2002 and with the results of HammerBlow Pro Forma for the twelve months ended
November 30, 2002 to represent the Unaudited Pro Forma Combined Statement of
Operations for the year ended December 31, 2002.

a)       HammerBlow acquired Tekonsha Towing Systems and Sure Pull Towing
         Systems ("Tekonsha/Sure Pull") from Dana Corporation on November 21,
         2002. HammerBlow's historical fiscal year results of operations do not
         include the results of Tekonsha / Sure Pull prior to that date. The
         HammerBlow Pro forma results include adjustments necessary to reflect
         the estimated effects of this acquisition as if it had occurred on
         December 1, 2001. The information for Tekonsha / Sure Pull has been
         derived from financial information available for the period from
         December 1, 2001 to the date of the acquisition. Financial information
         subsequent to the date of the acquisition is included in the results of
         HammerBlow.

         HammerBlow's fiscal year end is November 30 and the HammerBlow Pro
         Forma Statement of Operations for the twelve months ended November 30,
         2002 is included below (in millions). The impact of the acquisition of
         Tekonsha / Sure Pull is included in the consolidated balance sheet of
         HammerBlow at November 30, 2002.

        1)  Reflects increased depreciation and amortization of $0.2 million
            related to property and equipment and identified intangibles, based
            on estimated fair values at the date of acquisition and estimated
            remaining useful lives ranging from five to thirty years. Selling,
            general and administrative expense has been decreased $.3 million to
            reflect revenue for management services provided to a related
            entity.


                                      F-13



        2)  Reflects increased interest expense due to a change in capital
            structure. This includes $10 million in various term loans bearing
            an average rate of 5.6%, a $5.3 million revolver bearing a rate of
            5.5%, a purchase note of $.5M bearing 8.5%, and loan origination
            costs that are being amortized over the life of the related debt (3
            years).

        3)  Reflects the estimated tax effect of the above adjustments at a
            marginal tax rate of 38%.


    b)   As a result of the common stock issuance and related financing
         transactions that occurred on June 6, 2002, Metaldyne no longer
         provides a guarantee on certain TriMas leases. The existence of the
         guarantee required that the leases be accounted for as capitalized
         leases in periods prior to June 6, 2002. As a result of the guarantee
         release, these leases are now accounted for as operating leases. This
         adjustment reflects the recording of $0.9 million of rent expense
         offset by a reduction of $0.3 million of capitalized lease asset
         amortization expense for the twelve months ended December 31, 2002. An
         additional add-back of $0.9 million related to interest expense on the
         capitalized lease obligation for the twelve months ended December 31,
         2002 is included in adjustment (d) below as a result of eliminating
         this interest expense.

    c)   Pro forma adjustment to reflect ongoing corporate operating costs and
         related party contractual arrangements with Heartland, Metaldyne and
         the former owners of HammerBlow. Subsequent to June 6, 2002, certain
         stand-alone operating costs and related party contract costs have been
         recorded by the Company. The pro forma adjustment for the twelve months
         ended December 31, 2002 is incremental to such costs recorded after
         June 6, 2002.

                                                           DECEMBER 31, 2002

             Pro forma adjustment                             $     0.8
                                                              =========

         1)   Represents the Company's estimate of stand-alone corporate
              operating costs. Historically, such costs were allocated to
              TriMas via the Metaldyne management fee. These pro forma costs
              are premised upon certain assumptions necessary to operate on a
              stand-alone basis. While the Company believes its pro forma
              assumptions are reasonable, future operating costs may not
              approximate the amounts of such adjustments.

         2)   In connection with the June 6, 2002 transactions, TriMas entered
              into an advisory services agreement with Heartland at an annual
              fee of $4.0 million plus expenses.

         3)   Under the terms of a Corporate Services agreement, TriMas agreed
              to pay Metaldyne an annual fee of $2.5 million for human
              resources, information systems, treasury services, audit, internal
              audit, and tax, legal and other general corporate services.

         4)   The Company has entered into a management agreement with the
              former owners of HammerBlow to continue to provide shared services
              to a previously related entity. Annual fees to the Company for
              providing such services are $0.8 million. The pro forma adjustment
              includes only that amount which is incremental to the amount
              already considered in note (a) adjustment (1) above.

         5)   Adjustment to eliminate the historical 1% management fee paid to
              Metaldyne for corporate support and the historical management fees
              of $0.3 million paid to each of the previous shareholders of


                                      F-14


              HammerBlow and Highland respectively. Metaldyne continued to
              charge its management fee to TriMas through June 6, 2002, at which
              point the Company began to incur the costs summarized in items
              (1), (2), and (3) above.

              ----------------------------------

    d)   Pro forma adjustment to reflect interest expense related to borrowings
         under the Company's bank credit agreement as a result of the June 6,
         2002 transactions and the acquisition of Highland and HammerBlow, and
         as a result of issuance of the original notes and additional notes.

                                                                                     ================


         1)   The interest on the revolving credit facility is variable based on
              LIBOR plus 2.00% - 2.75%, depending on our leverage ratio. At
              December 31, 2002, the interest rate on the revolver was 4.44%
              (LIBOR plus 2.75%). TriMas has not utilized the revolver as of
              December 31, 2002 for operating purposes. The revolving credit
              facility was used to partially finance the acquisitions of
              HammerBlow and Highland. For purposes of the Unaudited Pro Forma
              Combined Statement of Operations, the revolving credit facility
              was assumed to be used to finance a portion ($57.1 million) of the
              Highland acquisition and interest expense related to these
              borrowings is $2.5 million. The revolver was also assumed to fund
              working capital requirements of HammerBlow and Highland during
              2002 and interest on these borrowings was $0.3 million.

              A 0.125% increase or decrease in the assumed interest rate for the
              revolving credit facility would change pro forma interest expense
              by $0.1 million for the twelve months ended December 31, 2002.

         2)   The interest rate on the term loan facility is variable based on
              LIBOR plus 2.50% - 2.75%, depending on the Company's leverage
              ratio. At December 31, 2002, the interest rate on the term loan
              facility was 4.44% (LIBOR plus 2.75%).

              A 0.125% increase or decrease in the assumed interest rate for the
              term loan facility would change pro forma interest expense by $0.3
              million for the twelve months ended December 31, 2002.

         3)   Represents interest accretion on deferred purchase price of $7.5
              million related to the acquisition of HammerBlow, due January
              2004.

         4)   Costs of approximately $31.9 million were incurred in connection
              with obtaining our senior credit facility ($13.1 million) and the
              issuance of the outstanding notes ($18.8 million). These amounts
              have been capitalized as debt issue costs and are being amortized
              using the interest method over 7.5 years and 10 years,
              respectively.

         5)   Consists of commitment fees on the revolving credit facility.

         6)   Represents accretion of discount on the original notes offered
              hereby to their face value of $352.8 million.

         7)   Represents amortization of premium on the additional notes to
              their face value of $85.0 million.

                               TRIMAS CORPORATION
               NOTES TO UNAUDITED PRO FORMA COMBINED BALANCE SHEET


The Unaudited Pro Forma Combined Balance Sheet includes Highland and HammerBlow
as of December 31, 2002 and November 30, 2002, respectively, and the adjustments
necessary to reflect the estimated effect of the acquisitions and the related
financing as if they had occurred on December 31, 2002.

a) The Unaudited Pro Forma Combined Balance Sheet assumes the following:

   1)       HammerBlow was acquired on January 30, 2003. The total
            consideration paid was $142.3 million ($142.2 million cash,
            including TriMas' $9.0 million existing equity interest, plus
            $2.6 million of transaction costs, less adjustment for
            compensation payments net of related tax benefits of $2.5
            million). The cash paid to fund the acquisition was provided
            through:

              i.     $63.3 million excess cash available from the $85 million
                     senior subordinated notes offering,

             ii.     $48.8 million draw on the revolving credit facility,

            iii.     $7.2 million net deferred purchase price to the former
                     shareholders of HammerBlow, and

             iv.     $14.0 million from the proceeds of the sale of 700,000 of
                     shares of common stock at $20 per share to Heartland.

            On February 14, 2003, the Company utilized the accounts
            receivable securitization facility to repay the revolving
            credit facility in the amount of $48.8 million. For purposes
            of the Unaudited Pro Forma Combined Financial Information, the
            accounts receivable securitization facility is assumed to have
            been used to fund the original draw of $48.8 million as the
            revolving credit facility was subsequently used to fund the
            Highland acquisition.

   2)       Highland was acquired on February 21, 2003. The total
            consideration paid was $73.1 million ($70.5 million cash, plus
            $1.3 million of transaction fees and $1.3 million for certain
            tax benefits). The cash paid to fund this acquisition was
            provided through: (i) $57.1 million draw on the revolving
            credit facility and (ii) $16.0 million from the proceeds of
            the sale of 800,000 of shares of common stock at $20 per share
            to Heartland.
