FORWARD-LOOKING STATEMENTS This report contains forward-looking statements about our financial condition, results of operations and business. You can find many of these statements by looking for words such as "may," "expect," "anticipate," "believe," "estimate" and similar words used in this report. These forward-looking statements are subject to numerous assumptions, risks and uncertainties. Because the statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by the forward-looking statements. We caution readers not to place undue reliance on the statements, which speak only as of the date of this report. The cautionary statements set forth above should be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue. We do not undertake any obligation to review or confirm analysts' expectations or estimates or to release publicly any revisions to any forward-looking statement to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events. Risks and uncertainties that could cause actual results to vary materially from those anticipated in the forward-looking statements contained in this report include general economic conditions in the markets in which we operate and industry-based and other factors more specific to us such as: o General Economic Conditions -- our business depends upon general economic conditions and we serve some customers in highly cyclical industries. o Acquisition Strategy -- if we are unable to identify attractive acquisition candidates, successfully integrate our acquired operations or realize the intended benefits of our acquisitions including actions we have identified as providing cost-saving opportunities, our business strategy and financial condition and results would be negatively affected. o Labor Stoppages -- we may be subject to work stoppages at our facilities or our customers may be subjected to work stoppages. o Product Liability and Warranty Claims -- we may incur material losses and costs as a result of product liability and warranty claims, as well as legacy liability issues. o Environmental Matters -- we may be materially and adversely affected by compliance obligations and liabilities under environmental laws and regulations. o Raw Material and Other Costs -- increases in our raw material, labor, or energy costs or the loss of a substantial number of our suppliers could adversely affect us. o Competition -- we operate in competitive industries and may experience increased competition. o Changing Technology -- our products are typically highly engineered or customer-driven and, as such, we are subject to risks associated with changing technology and manufacturing techniques. o Dependence on Key Individuals and Relationships -- we depend on the services of key individuals and relationships. o International Operations -- a growing portion of our sales may be derived from international sources, which exposes us to certain risks. o Goodwill and Intangible Assets -- we have significant goodwill and intangible assets, and future impairment could have a material negative impact on our financial condition and results. o Control by Principal Stockholder -- we are controlled by Heartland Industrial Partners ("Heartland"), whose interests in our business may be different than those of our other investors. 1

o Substantial Leverage and Debt Service -- we have substantial debt, interest and lease payment requirements that may restrict our future operations and impair our ability to meet our obligations. o Substantial Restrictions and Covenants -- restrictions in our credit facility and under the indenture governing our notes may impact our ability to implement certain operational and financial strategies. We disclose important factors that could cause our actual results to differ materially from our expectations under "Management's Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere in this report. These cautionary statements qualify all forward-looking statements attributed to us or persons acting on our behalf. When we indicate that an event, condition or circumstance could or would have an adverse effect on us, we mean to include effects upon our business, financial and other conditions, results of operations and ability to make payments on the notes. 2

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 1. BASIS OF PRESENTATION TriMas Corporation ("TriMas" or the "Company") is a global manufacturer of products for commercial, industrial and consumer markets. The Company is principally engaged in four segments with diverse products and market channels. Cequent Transportation Accessories produces vehicle hitches and receivers, sway controls, weight distribution and fifth wheel hitches, hitch mounted accessories, roof racks, trailer couplers, winches, jacks, trailer brakes and lights and other vehicle and trailer accessories and components that are distributed through independent installers and retail outlets. Rieke Packaging Systems is a leading source of closures and dispensing systems for steel and plastic industrial and consumer packaging applications. The Fastening Systems group produces a wide range of large and small diameter standard and custom-designed ferrous, nonferrous and special alloy fasteners used in automotive and industrial applications, and highly engineered specialty fasteners for the global aerospace industry. The Industrial Specialties group produces flame-retardant facings and jacketing and insulation tapes used in conjunction with fiberglass insulation, pressure-sensitive specialty tape products, high-pressure and low-pressure cylinders for the transportation, storage and dispensing of compressed gases, metallic and nonmetallic industrial gaskets, specialty precision tools such as center drills, cutters, end mills, reamers, master gears, gages and punches, specialty engines and service parts and specialty ordnance components and weapon systems. On May 9, 2003, the Company acquired a fasteners manufacturing business ("Fittings") from Metaldyne Corporation ("Metaldyne") for approximately $22.7 million on a debt free basis. The acquired business is a leading manufacturer of specialized fittings and cold-headed parts used in automotive and industrial applications. The transaction was funded by a combination of borrowings under the Company's revolving credit facility and a cash equity contribution by Heartland. The acquired business had 2002 revenues of approximately $16.7 million. Because the Company and Metaldyne are under common control, this transaction was accounted for as a reorganization of entities under common control and, accordingly, the Company did not establish a new basis of accounting in the assets or liabilities of Fittings. The Company's reported results from prior periods have been restated to include the financial results of Fittings. Prior to June 6, 2002 and the common stock issuance related financing transactions discussed in Note 2, the accompanying financial statements represented the combined assets and liabilities and results of operations of certain subsidiaries and divisions of subsidiaries of Metaldyne which comprised TriMas. The combined financial statements include all revenues and costs directly attributed to the Company as well as an estimate of direct and indirect Metaldyne corporate administrative costs attributed to TriMas, based on a management fee allocation that approximated 1% of net sales. This allocation of costs is based on estimates that management believes are reasonable in the circumstances. However, the charges included herein are not necessarily indicative of the amounts that would have been reported if the Company had operated as an unaffiliated company. The accompanying financial statements include the accounts of the Company and its subsidiaries and in the opinion of management, contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Certain prior year items have been reclassified to conform to the current year presentation. Results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying financial statements and notes thereto should be read in conjunction with the Company's 2002 Annual Report on Form 10-K. 2. RECAPITALIZATION On June 6, 2002, the Company, Metaldyne and Heartland entered into a stock purchase agreement under which Heartland and other co-investors invested $265 million in the Company to acquire approximately 66% of the Company's common stock on a fully diluted basis. Under the terms of the stock purchase agreement, Metaldyne retained shares of the Company's common stock valued at $120 million and received a warrant to purchase 750,000 7

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) shares of common stock at par value of $.01 per share, valued at $15 million. At June 30, 2003, this warrant had not been exercised. The common stock and warrants were valued based upon the cash equity investment made by Heartland and the other investors. At June 30, 2003, Metaldyne owned 27.7% of the Company's common stock on a fully diluted basis. As Heartland is both the Company's and Metaldyne's controlling shareholder, the June 6, 2002 and related transactions were accounted for as a reorganization of entities under common control and, accordingly, the Company has not established a new basis of accounting in its assets or liabilities. Additional adjustments to paid-in capital related to Metaldyne's investment in the Company may be recorded in subsequent periods to reflect finalization of certain estimated amounts at the transaction closing date. 3. ACQUISITIONS On January 30, 2003, 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. The total consideration paid was $145.2 million (including our previous investment of $9.0 million). Of this amount, $7.2 million, net of the purchase price, was deferred and is payable in January 2004. HammerBlow is a manufacturer and distributor of towing, trailer, and other vehicle accessories throughout North America and the purchase includes The HammerBlow Corporation, Hidden Hitch, Tekonsha Towing Systems ("Tekonsha") and Sure Pull Towing Systems ("SurePull"). HammerBlow acquired Tekonsha and SurePull from Dana Corporation on November 21, 2002. On February 21, 2003, the Company acquired Highland Group Industries ("Highland") from the shareholders and option holders of Highland and FNL Management Corp. The total consideration paid was $73.5 million. Highland is a market-leading supplier of cargo management products and a full line supplier of vehicle protection products, specializing in products that help people safely load, anchor, secure, tow, carry, trailer, and organize cargo, as well as protect the vehicle and its cargo area. The acquisitions of HammerBlow and Highland provide additional opportunities to leverage new product extensions and innovations in our towing and trailer products businesses with customers in new markets through enhanced brand awareness and distribution, particularly in the end consumer retail channel. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the acquisition dates. The Company is in the process of obtaining finalized third-party valuations of certain intangible assets and determining costs of restructuring plans associated with these businesses. The allocation of the purchase price is subject to refinement of these estimates and consists of the following (in thousands): HAMMERBLOW HIGHLAND TOTAL ------------ ------------ ------------- Current assets.......................................$ 36,300 $ 18,770 $ 55,070 Property and equipment............................... 22,200 5,980 28,180 Other intangible assets.............................. 54,290 24,700 78,990 Goodwill............................................. 72,330 35,900 108,230 Deferred taxes and other............................. 2,380 1,280 3,660 ------------ ------------ ------------- Total assets acquired.......................... 187,500 86,630 274,130 ------------ ------------ ------------- Current liabilities.................................. 21,780 3,140 24,920 Deferred tax liabilities............................. 20,470 9,950 30,420 ------------ ------------ ------------- Total liabilities assumed...................... 42,250 13,090 55,340 ------------ ------------ ------------- Net assets acquired............................$ 145,250 $ 73,540 $ 218,740 ============ ============ ============= 8

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) The estimated fair values of inventories acquired were increased $4.0 million from historical amounts, of which approximately $1.6 million and $2.3 million of this amount was included in cost of sales during the quarters ended June 30, 2003 and March 30, 2003, respectively. Based on preliminary estimates, of the $79.0 million of acquired other intangible assets, $40.9 million was assigned to Customer Relationships with a useful life of 15 years, $34.6 million was assigned to Trademarks with a useful life of 40 years and the remaining $3.5 million was assigned to Technology and Other with useful lives ranging from 7 - 10 years. The $108.2 million of goodwill is assigned to the Cequent Transportation Accessories segment. The results of these acquisitions are included in the Company's June 30, 2003 financial statements from the respective dates of acquisition. The following selected unaudited pro forma combined results of operations for the Company, HammerBlow and Highland have been prepared assuming that the acquisitions occurred at the beginning of the respective periods. The selected unaudited pro forma combined results are based on the historical information for TriMas and Highland and pro forma combined results of operations for HammerBlow assuming that the acquisition of Tekonsha and SurePull occurred at the beginning of the respective periods. The pro forma financial information is not necessarily indicative of the combined results of operations that would have been attained had the acquisitions taken place at the beginning of 2003 and 2002, nor are they indicative of future results. The expense associated with the step-up in basis of inventory has been excluded as it is not a recurring expense.

Estimated amortization expense for the next five fiscal years beginning after December 31, 2002 is as follows: 2003 -- $17.8 million; 2004 -- $18.2 million; 2005 -- $18.1 million; 2006 -- $16.6 million; and 2007 -- $15.9 million. 5. RESTRUCTURINGS During the second quarter of 2003, in conjunction with the acquisition of Fittings, the Company adopted a plan to close one additional manufacturing facility within its Fastening Systems group and consolidate those operations into the remaining three manufacturing facilities. This action will result in the elimination of approximately 160 positions, of which approximately 30 have been eliminated as of June 30, 2003. The plan is expected to be completed in 2004. The Company has recorded charges of approximately $2.0 million related to the consolidation, of which approximately $0.9 million relates to the curtailment of a defined benefit pension plan for certain union-hourly employees and $1.1 million relates to a reserve for severance obligations. As of June 30, 2003, costs of approximately $0.3 million had been charged against this reserve. Also during the second quarter of 2003, the Company adopted a plan to centralize certain gasket applications in its Industrial Specialties group within a single facility. In addition, the group will rationalize the back office general and administrative support within its branch service centers. This action will result in the elimination of approximately 40 positions, of which approximately 30 have been eliminated as of June 30, 2003. The plan is expected to be completed in 2004. The Company has established a reserve for severance obligations of approximately $1.0 million in connection with this plan. As of June 30, 2003, costs of approximately $0.1 had been charged against this reserve. During the first quarter of 2003, the Company established a preliminary estimate of restructuring costs associated with its acquisitions of HammerBlow and Highland of $5.2 million, of which approximately $2.2 million related to facility closure costs and $3.0 million related to severance obligations. No costs were charged against this reserve during the six months ended June 30, 2003. 10

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) Following the November 2000 acquisition of Metaldyne by Heartland, Metaldyne employed a new senior management team for TriMas to reorganize and restructure the TriMas business units and implement cost savings projects. The new management team developed and launched six major projects and several smaller initiatives to consolidate sub-scale business units and redundant plants and to streamline administrative costs. The following table summarizes the purchase accounting adjustments established to reflect the November 2000 actions and subsequent related activity (in thousands): CLOSURE SEVERANCE COSTS TOTAL ------------ ------------ --------- Reserve at December 31, 2002....................................... $ 4,590 $ 2,480 $ 7,070 Cash.............................................................

To date, approximately 405, 55 and 100 have been eliminated in the Cequent Transportation Accessories, Rieke Packaging Systems and Fastening Systems groups, respectively, as of June 30, 2003, and the Company expects the remaining actions to be completed in 2004. 6. ACCOUNTS RECEIVABLE SECURITIZATION As part of the June 2002 financing transactions, TriMas established a receivables securitization facility and organized TSPC, Inc. ("TSPC"), a wholly-owned subsidiary, to sell trade accounts receivable of substantially all domestic business operations. Prior to June 2002, TriMas sold certain of its accounts receivable to MTSPC, Inc. ("MTSPC"), a wholly owned subsidiary of Metaldyne. TSPC from time to time may sell an undivided fractional ownership interest in the pool of receivables up to approximately $125 million to a third party multi-seller receivables funding company. The net proceeds of sale are less than the face amount of accounts receivable sold by an amount that approximates the purchaser's financing costs, which amounted to a total of $0.8 million and $0.9 million for the six months ended June 30, 2003 and 2002, respectively. At June 30, 2003 and December 31, 2002, no receivables were sold under this arrangement and the Company had $61.6 million available but not utilized as of the balance sheet date. The discount rate at June 30, 2003 was 2.27%. The usage fee under the facility is 1.5%. In addition, the Company is required to pay a fee of 0.5% on the unused portion of the facility. This facility expires in June 2005. 7.

LONG-TERM DEBT The Company's long-term debt at June 30, 2003, net of the unamortized discount of $2.6 million and unamortized premium of $0.8 million from face value of the Company's 9 7/8% senior subordinated notes, is as follows (in thousands): DECEMBER 31, JUNE 30, 2003 2002 --------------- --------------- Senior term loan..................................................... $ 332,930 $ 259,375 9 7/8% senior subordinated notes, due June 2012 ("Notes")............ 436,010 435,975 Other................................................................ 8,320 830 ------------- ------------- 777,260 696,180 Less: Current maturities............................................ 11,470 2,990 ------------- ------------- Long-term debt....................................................... $ 765,790 $ 693,190 ============= ============= On June 6, 2003, the Company amended and restated its credit facility ("Credit Facility") to modify certain financial covenants, increase the term loan facility from $260 million to $335 million and reduce the incremental term loan capacity by $75 million to $125 million. The Credit Facility, as amended, provides for this uncommitted $125 million incremental term loan facility for one or more permitted acquisitions. In connection with the amendment and restatement, the Company capitalized debt issuance costs of approximately $1.9 million, which will be amortized using the effective interest method over the life of the Credit Facility. The amended and restated Credit Facility consists of a $335 million senior term loan which matures December 31, 2009 and is payable in quarterly installments of $0.8 million. The Credit Facility also includes a senior revolving credit facility with a total principal commitment of $150 million, including up to $100 million for one or more permitted acquisitions, which matures December 31, 2007. The Credit Facility allows the Company to issue letters of credit, not to exceed $40 million in aggregate, against revolving credit facility commitments. The Company had letters of credit of approximately $23.8 and $23.5 million issued and outstanding at June 30, 2003 and December 31, 2002, respectively. Borrowings under the Credit Facility bear interest at the Company's option at either a base rate used by JPMorgan Chase Bank, plus an applicable margin, or a Eurodollar rate on deposits for one, two, three or six month periods (or nine or twelve month periods if, at the time of the borrowing, all lenders agree to make such a duration available), plus an applicable margin. The applicable margin on borrowings is subject to change, depending on the Company's Leverage Ratio, as defined, and is 2.25% on base rate loans and 3.25% on Eurodollar loans at June 30, 2003. The effective interest rate on Credit Facility borrowings was 4.47% at June 30, 2003 and 4.44% at December 31, 2002. 12

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) The Credit Facility contains negative and affirmative covenants and other requirements affecting the Company and its subsidiaries, including among others: restrictions on incurrence of debt, except for permitted acquisitions and subordinated indebtedness, liens, mergers, investments, loans, advances, guarantee obligations, acquisitions, asset dispositions, sale-leaseback transactions greater than $75 million if sold at fair market value, hedging agreements, dividends and other restricted junior payments, stock repurchases, transactions with affiliates, restrictive agreements and amendments to charters, by-laws, and other material documents. The Credit Facility also requires the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined), interest expense ratio (EBITDA over cash interest expense, as defined) and a capital expenditures covenant. The Company was in compliance with its covenants at June 30, 2003. The Notes indenture contains negative and affirmative covenants and other requirements that are comparable to those contained in the Credit Facility. At June 30, 2003, the Company was in compliance with all such covenant requirements. The Company paid cash for interest of approximately $29.7 million for the six months ended June 30, 2003. For the six months ended June 30, 2002, interest expense allocated to TriMas was paid by Metaldyne. 10. LEASES TriMas leases certain equipment and plant facilities under non-cancelable operating leases. Rental expense totaled approximately $6.9 million and $1.2 million in the six months ended June 30, 2003 and 2002, respectively. In the first and second quarters of 2003, the Company entered into sale-leaseback arrangements with third-party lenders for certain of its machinery and equipment and facilities. These leases are accounted for as operating leases. The Company has an eight year lease term with respect to machinery and equipment which requires annual lease payments of approximately $8.4 million. The Company has a fifteen year lease term with respect to its leaseback of two facilities which require annual lease payments of approximately $0.9 million. The proceeds from these transactions were applied against outstanding balances under the Company's revolving credit facility. In connection with these sale-leaseback transactions, the Company recorded losses of approximately $18.1 million, which is included in other, net in the accompanying statement of operations. 11. COMMITMENTS AND CONTINGENCIES A civil suit was filed in the United States District Court for the Central District of California in April 1983 by the United States of America and the State of California under the Federal Superfund law against over 30 defendants, including a subsidiary of the Company, for alleged release into the environment of hazardous substances disposed of at the Stringfellow Disposal Site in California. The plaintiffs have requested, among other things, that the defendants clean up the contamination at that site. A consent decree has been entered into by the plaintiffs and the defendants, including us, providing that the consenting parties perform partial remediation at the site. The State of California has agreed to take over clean-up of the site, as well as responsibility for governmental entities' past response costs. Additionally, TriMas and approximately 60 other entities including the State were defendants in a toxic tort suit brought in the Superior Court of the State of California in May 1998 by various persons residing in the area of the site and seeking damages for alleged personal injuries claimed to arise from exposure to contaminants from the site. The Superior Court of the State of California issued an order dismissing all plaintiffs in the action. A final judgment dismissing the matter without any recovery by plaintiffs was entered by the court on July 23, 2003. Another civil suit was filed in the United States District Court for the Central District of California in December 1988 by the United States of America and the State against more than 180 defendants, including TriMas, for alleged release into the environment of hazardous substances disposed of at the Operating Industries, Inc. site in California. This site served for many years as a depository for municipal and industrial waste. The plaintiffs have requested, among other things, that the defendants clean up the contamination at that site. Consent decrees have 13

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) been entered into by the plaintiffs and a group of defendants, including TriMas, providing that the consenting parties perform certain remedial work at the site and reimburse the plaintiffs for certain past costs incurred by the plaintiffs at the site. We estimate that the Company's share of the clean-up will not exceed $450,000, for which the Company has received insurance proceeds. As of August 8, 2003, the Company is party to approximately 612 pending cases involving approximately 30,427 claimants alleging personal injury from exposure to asbestos containing materials formerly used in gaskets (both encapsulated and otherwise) manufactured or distributed by certain of our subsidiaries for use in the petrochemical refining and exploration industries. The Company manufactured three types of gaskets and has ceased the use of asbestos in its products. The Company believes that many of the pending cases relate to locations at which none of our gaskets were distributed or used. In addition, TriMas acquired various companies to distribute the Company's products and also had distributed gaskets of other manufacturers prior to acquisition. Total settlement costs (exclusive of defense costs) for all such cases, some of which were filed over 12 years ago, have been approximately $2.3 million. The Company does not have significant primary insurance to cover its settlement and defense costs. The Company believes that there may be excess insurance policies of former owners available to it that the Company is in the process of reconstructing, but such insurance may not be available. Based upon the Company's experience to date and other available information, the Company does not believe that these cases will have a material adverse effect on its financial condition or future results of operations. However, the Company may be subjected to significant additional claims in the future, the cost of settling cases in which product identification can be made may increase, and the Company may be subjected to further claims in respect of the former activities of its acquired gasket distributors. The Company has provided reserves based upon its present knowledge and, subject to future legal and factual developments, does not believe that the ultimate outcome of any of these litigations will have a material adverse effect on its consolidated financial position and future results of operations and cash flow. However, there can be no assurance that future legal and factual developments will not result in a material adverse impact on our financial condition and future results of operations. The Company is subject to other claims and litigation in the ordinary course of business, but does not believe that any such claim or litigation will have a material adverse effect on the Company's financial position or results of operations. 12. RELATED PARTIES Metaldyne Corporation Prior to June 6, 2002, the Company was wholly-owned by Metaldyne and participated in joint activities including employee benefits programs, legal, treasury, information technology and other general corporate activities. In April 2003, TriMas repurchased one million shares of its common stock from Metaldyne at $20 per share, the same price as it was valued on June 6, 2002. This sale decreased Metaldyne's ownership percentage in TriMas from approximately 31.4% to approximately 27.7% on a fully diluted basis. In connection with the common stock issuance and related financing transactions, TriMas assumed certain liabilities and obligations of Metaldyne, mainly comprised of contractual obligations to former TriMas employees, tax related matters, benefit plan liabilities and reimbursements to Metaldyne for normal course payments to be made on TriMas' behalf. The amount of these liabilities and obligations were $15.9 million and $21.9 million as of June 30, 2003 and December 31, 2002, respectively. These amounts are payable at various dates over the next two years and are included in Due to Metaldyne in the accompanying consolidated balance sheets. The Company is also party to a corporate services agreement with Metaldyne. Under the terms of the agreement, TriMas pays Metaldyne an annual services fee of $2.5 million in exchange for human resources, information technology, internal audit, tax, legal and other general corporate services and remittance of certain third-party charges on TriMas' behalf. 14

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) Heartland Industrial Partners The Company is party to an advisory services agreement with Heartland at an annual fee of $4.0 million plus expenses. During the six months ended June 30, 2003, the Company incurred $2.3 million in connection with this agreement and this amount is included in selling, general and administrative expense in the accompanying consolidated statement of operations. Also in the quarter ended March 30, 2003, TriMas paid Heartland approximately $2.1 million in advisory services in connection with the acquisitions of HammerBlow and Highland. Such fees have been capitalized as transaction costs as a component of total consideration paid and allocated to the fair value of assets acquired and liabilities assumed in the respective acquisitions. 13. SEGMENT INFORMATION TriMas' reportable operating segments are business units that provide unique products and services. Each operating segment is independently managed, requires different technology and marketing strategies and has separate financial information evaluated regularly by the Company's chief operating decision maker in determining resource allocation and assessing performance. During the first quarter of 2003, the Company re-aligned its operating segments and appointed a group president for its Fastening Systems group. Prior period segment information has been revised to conform to the current structure and presentation. TriMas has four operating segments involving the manufacture and sale of the following products: CEQUENT TRANSPORTATION ACCESSORIES -- Vehicle hitches and receivers, sway controls, weight distribution and 5th wheel hitches, hitch mounted accessories, roof racks, trailer couplers, winches, jacks, trailer brakes and lights and other vehicle and trailer accessories. RIEKE PACKAGING SYSTEMS -- Closures and dispensing systems for steel and plastic industrial and consumer packaging applications. FASTENING SYSTEMS -- Large and small diameter standard and custom-designed ferrous, nonferrous and special alloy fasteners, specialized fittings and cold-headed parts used in automotive and industrial applications, and highly engineered specialty fasteners for the domestic and international aerospace industry. INDUSTRIAL SPECIALTIES -- Flame-retardant facings and jacketing and insulation tapes used in conjunction with fiberglass insulation, pressure-sensitive specialty tape products, high-pressure and low-pressure cylinders for the transportation, storage and dispensing of compressed gases, metallic and nonmetallic industrial gaskets, specialty precision tools such as center drills, cutters, end mills, reamers, master gears, gages and punches, specialty engines and service parts and specialty ordnance components and weapon systems. The Company uses Earnings (Operating Profit) Before Interest, Taxes, Depreciation and Amortization ("EBITDA") as an indicator of operating performance and as a measure of cash generating capabilities. EBITDA is one of the primary measures used by management to evaluate performance. Legacy stock award expense represents a contractual obligation from the November 2000 acquisition which will be fully paid in January 2004. 15

IMPACT OF NEWLY ISSUED ACCOUNTING PRONOUNCEMENTS In January 2003, the Financial Accounting Standards Board ("FASB') issued FASB Interpretation ("FIN") 46, "Consolidation of Variable Interest Entities, an Interpretation of ARB 51." FIN 46 requires primary beneficiaries in a variable interest entity to consolidate the entity even if the primary beneficiary does not have a majority voting interest. This consolidation requirement is effective immediately for any variable interest entity created on or after January 31, 2003, and after June 30, 2003 for entities created before January 31, 2003. In addition, FIN 46 requires disclosure of information regarding guarantees or loss exposures related to a variable interest entity created prior to January 31, 2003 in financial statements issued after January 31, 2003. The adoption of this statement did not have any effect on the Company's results of operations or financial condition. In May 2003, the FASB issued Statement of Financial Accounting Standards ("SFAS") No. 150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity." SFAS No. 150 provides guidance for how a company should classify and measure certain financial instruments that have characteristics of both liabilities and equity. SFAS No. 150 is effective immediately for any qualifying financial instruments issued after May 31, 2003 and becomes effective for existing issuance in the third quarter of 2003. The Company does not believe the adoption of SFAS No. 150 will have a material impact on its financial condition or results of operations. 16

TRIMAS CORPORATION NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED) 15. SUBSEQUENT EVENT On July 21, 2003, the Company launched an exchange offer for its $85 million aggregate principal amount of 9 7/8% senior subordinated notes due 2012 for a like amount of outstanding 9 7/8% senior subordinated notes due 2012. The exchange offer is scheduled to expire on August 20, 2003. The exchange offer will not raise new cash proceeds for the Company and was made in accordance with contractual commitments under the registration rights agreement dated December 10, 2002. 16. SUPPLEMENTAL GUARANTOR CONDENSED COMBINING AND CONSOLIDATING FINANCIAL INFORMATION Under an indenture dated June 6, 2002, TriMas Corporation, the parent company ("Parent"), issued 9 7/8% Senior Subordinated Notes due 2012 in a total principal amount of $437.8 million (face value). These Notes are guaranteed by substantially all of the Company's domestic subsidiaries ("Guarantor Subsidiaries"). All of the Guarantor Subsidiaries are 100% owned by the Parent and their guarantee is full, unconditional, joint and several. The Company's non-domestic subsidiaries and TSPC, Inc. have not guaranteed the Notes ("Non-Guarantor Subsidiaries"). The Guarantor Subsidiaries have also guaranteed amounts outstanding under the Company's Credit Facility. The accompanying supplemental guarantor condensed, combining or consolidating financial information is presented on the equity method of accounting for all periods presented. Under this method, investments in subsidiaries are recorded at cost and adjusted for the Company's share in the subsidiaries' cumulative results of operations, capital contributions and distributions and other changes in equity. Elimination entries relate primarily to the elimination of investments in subsidiaries and associated intercompany balances and transactions. Prior to June 6, 2002, the Parent held equity investments directly in certain of the Company's wholly-owned Non-Guarantor Subsidiaries, and equity in these investees is included in the Parent column of the accompanying condensed combining financial information for all periods presented. Subsequent to June 6, 2002, all investments in non-domestic subsidiaries are held directly at TriMas Company LLC, a wholly-owned subsidiary of TriMas Corporation and Guarantor Subsidiary, and equity in non-domestic subsidiary investees for all periods subsequent to June 30, 2002 is included in the Guarantor Subsidiary column of the accompanying consolidating financial information.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS INTRODUCTION We are an industrial manufacturer of highly engineered products serving niche markets in a diverse range of commercial, industrial and consumer applications. Effective January 1, 2003, TriMas reorganized its business operations and formed a Fastening Systems segment consisting of our industrial fasteners businesses which were previously part of Industrial Specialties. As a result, prior period financial information has been reclassified to conform to this presentation. We have four operating groups or segments: Cequent Transportation Accessories, Rieke Packaging Systems, Fastening Systems and Industrial Specialties. SEGMENT INFORMATION The following table summarizes financial information of our four operating segments.

(2) Legacy stock award expense represents a contractual obligation from the November 2000 acquisition of Metaldyne by Heartland. TriMas assumed a portion of this liability in connection with the separation and recapitalization of the Company in June 2002. 26

RESULTS OF OPERATIONS THREE MONTHS ENDED JUNE 30, 2003 COMPARED WITH THREE MONTHS ENDED JUNE 30, 2002 Including $47.4 million in sales from entities acquired during the period, net sales for the three months ended June 30, 2003 increased approximately 21.5% compared to the three months ended June 30, 2002. Excluding the impact of acquisitions, net sales decreased 1.5%. Net sales for Cequent Transportation Accessories increased 43.4%. This increase was due to the $47.4 million impact from the acquisitions of HammerBlow and Highland. Excluding the impact of acquisitions, Cequent Transportation Accessories sales decreased 10.6% due to weakness in demand in the overall market for towing and trailer accessories, principally in the RV and marine markets and retail distribution through mass merchandisers and independent retail outlets. Rieke Packaging Systems net sales increased 17.9% primarily due to the benefit of sales of new products. Fastening Systems net sales decreased 6.5%, as we have continued to see weakness in demand for our fastener products in the general distribution and aerospace channels. Industrial Specialties net sales increased 7.1%. The increase in sales in the Industrial Specialties group was due to improved demand for our products across the commercial construction, energy and petrochemical, general industrial and defense markets. Operating profit margins approximated 9.0% and 14.0% for the three months ended June 30, 2003 and June 30, 2002, respectively. Excluding the impact of acquisitions, the operating profit margin for the three months ended June 30, 2003 approximated 6.9%. Operating profit for the three months ended June 30, 2003 was $22.4 million, a decrease of $6.3 million compared to the three months ended June 30, 2002. Excluding the $8.4 million favorable impact from acquisitions, operating profit decreased $14.7 million. This reduction in operating profit is partially attributed to $5.6 million of incremental costs and operational inefficiencies incurred primarily in connection with restructuring activities within our Cequent Transportation Accessories and Fastening Systems groups and $3.0 million of incremental charges related to severance, move and other restructuring costs. The costs related to Cequent Transportation Accessories resulted from the continued ramp-up of our Goshen, Indiana manufacturing facility, the expansion of operations in Reynosa, Mexico, and the closure of our Elkhart, Indiana and Canton, Michigan manufacturing facilities. We finalized these closures in the second quarter of 2003. During the three months ended June 30, 2003 the Company recognized $1.6 million of non-recurring costs as a result of the one time step-up in basis of acquired inventory. Additionally, there is $2.3 million of incremental lease costs, $.3 million of incremental legacy stock award expense (this expense will run off completely in 2003), $1.2 million of incremental costs associated with our separation from Metaldyne (such costs include incremental employment and operating costs), and $1.1 million of management fees and expenses incurred to Heartland. These costs have been offset by $.5 million of reduced depreciation and amortization expense primarily attributable to our use of leasing. Selling, general and administrative costs were approximately $39.7 million, or 15.9% of net sales, for the three months ended June 30, 2003 as compared with $29.3 million, or 14.2% of net sales, in the prior year. The increase of $10.4 million is primarily due to the $7.4 million impact of acquired operations and increased costs associated with our separation from Metaldyne. Such costs principally include $1.2 million of incremental employment and operating costs for the establishment of a corporate office (previously considered part of the Metaldyne management fee) and $1.1 million of management fees and expenses incurred to Heartland. Other expense, net was $22.3 million for the three months ended June 30, 2003, a $4.0 million increase over the $18.3 million of expense for the three months ended June 30, 2002. The Company recorded a $5.6 million loss, net from the sale and disposition of fixed assets in the second quarter of 2003. This loss occurred primarily due to the sale and leaseback of certain manufacturing equipment and facilities during the second quarter. In connection with these sale-leaseback transactions, the Company received $25.9 million of net proceeds which were used to pay down amounts outstanding under our revolving credit facility. Net loss for the three months ended June 30, 2003 was $1.4 million as compared to net income of $6.7 million for the three months ended June 30, 2002. In addition to the items noted above, the net loss for the three months ended June 30, 2003 was impacted by increased provisions for taxes on foreign income and state taxes in the U.S. 27

SIX MONTHS ENDED JUNE 30, 2003 COMPARED WITH SIX MONTHS ENDED JUNE 30, 2002 Including $74.5 million in sales from entities acquired during the period, net sales for the six months ended June 30, 2003 increased approximately 16.7% compared to the six months ended June 30, 2002. Excluding the impact of acquisitions, net sales decreased 1.8%. Net sales for Cequent Transportation Accessories increased 37.8%. This increase was due to the $74.5 million impact from the acquisitions of HammerBlow and Highland. Excluding the impact of acquisitions, Cequent Transportation Accessories sales decreased 7.9% due to weakness in demand in the overall market for towing and trailer accessories, principally in the RV and marine markets and retail distribution through mass merchandisers and independent retail outlets. Rieke Packaging Systems net sales increased 15.9% primarily due to the benefit of sales of new products. Fastening Systems net sales decreased 7.3%, as we have continued to see weakness in demand for our fastener products in the general distribution and aerospace channels. Industrial Specialties net sales increased 2.3%. The increase in sales in the Industrial Specialties group was due to improved demand for our products across the commercial construction, energy and petrochemical, general industrial and defense markets primarily in the second quarter of 2003. Operating profit margins approximated 8.4% and 13.4% for the six months ended June 30, 2003 and June 30, 2002, respectively. Excluding the impact of acquisitions, the operating profit margin for the six months ended June 30, 2003 approximated 7.6%. Operating profit for the six months ended June 30, 2003 was $39.6 million, a decrease of $14.1 million compared to the six months ended June 30, 2002. Excluding the $9.6 million favorable impact from acquisitions, operating profit decreased $23.7 million. This reduction in operating profit is partially attributed to $8.6 million of incremental costs and operational inefficiencies incurred primarily in connection with restructuring activities within our Cequent Transportation Accessories and Fastening Systems groups and $4.1 million of incremental charges related to severance, move and other restructuring costs. The costs related to Cequent Transportation Accessories resulted from the continued ramp-up of our Goshen, Indiana manufacturing facility, the expansion of operations in Reynosa, Mexico, and the closure of our Elkhart, Indiana and Canton, Michigan manufacturing facilities. We finalized these closures in the second quarter of 2003. During the six months ended June 30, 2003, the Company recognized $3.9 million of non-recurring costs as a result of the one time step-up in basis of acquired inventory. Additionally, there is $3.6 million of incremental lease costs, $.8 million of incremental legacy stock award expense (this expense will run off completely in 2003), $2.4 million of incremental costs associated with our separation from Metaldyne (such costs include incremental employment and operating costs), and $2.3 million of management fees and expenses incurred to Heartland. These costs have been offset by $2.0 million of reduced depreciation and amortization expense attributed primarily to our use of leasing. Selling, general and administrative costs were approximately $75.3 million, or 16.1% of net sales, for the six months ended June 30, 2003 as compared with $56.5 million, or 14.1% of net sales, in the prior year. The increase is primarily due to the impact of acquired operations ($11.6 million) and increased costs associated with our separation from Metaldyne. Such costs principally include $2.4 million of incremental employment and operating costs for the establishment of a corporate office (previously considered part of the Metaldyne management fee) and $2.3 million of management fees and expenses incurred to Heartland. Other expense, net was $51.0 million for the six months ended June 30, 2003, a $13.6 million increase over the $37.4 million of expense for the six months ended June 30, 2002. The Company recorded a $17.6 million loss, net from the sale and disposition of fixed assets in the first six months of 2003. This loss occurred primarily due to the sale and leaseback of certain manufacturing equipment and facilities entered into in 2003. In connection with these sale-leaseback transactions, the Company received $62.1 million of net proceeds which were used to pay down amounts outstanding under our revolving credit facility. The Company also received proceeds of approximately $5.9 million from the sale of certain facilities and equipment, and used these proceeds to pay down amounts outstanding under our revolving credit facility. The $0.5 million reduction in interest expense was due to lower total indebtedness overall, resulting from the recapitalization of the Company in June 2002. Net loss for the six months ended June 30, 2003 was $8.4 million as compared to a net loss of $26.1 million for the six months ended June 30, 2002. The results for the six months ended June 30, 2002 include a charge of $36.6 million for the cumulative effect on prior years of a change in recognition and measurement of goodwill impairment. 28

LIQUIDITY AND CAPITAL RESOURCES Cash provided by operating activities for the six months ended June 30, 2003 was approximately $6.6 million as compared to cash used in operating activities of approximately $58.1 million for the comparable period a year ago. The primary reason for the difference of $64.7 million was due to the repurchase of $74.5 million of receivables as a result of exiting Metaldyne' accounts receivable securitization facility in June 2002, offset by a net increase in working capital of $10.6 million during the current year. Capital expenditures were $10.4 million for the six months ended June 30, 2003, as compared with $13.7 million for the comparable period in 2002. Our credit facility, as amended and restated on June 6, 2003, includes a $150 million revolving credit facility and a $335 million term loan facility. Up to $100 million of our revolving credit facility is available to be used and kept outstanding for one or more permitted acquisitions. The credit facility, as amended, also provides for an uncommitted $125 million incremental term loan facility for one or more permitted acquisitions. Our revolving credit balances fluctuate daily based upon our working capital and other ordinary course needs. Availability under our revolving credit facility depends upon, among other things, compliance with the financial covenants in our credit facility. Our other important source of liquidity is our $125 million accounts receivable securitization facility, under which we have the ability to sell eligible accounts receivable to a third-party multi-seller receivables funding company. At June 30, 2003, the Company had no amounts outstanding under the accounts receivable facility and $61.6 million available, but not utilized. At June 30, 2003, the Company had $22.4 million of available cash and could incur up to $39.2 million of additional senior indebtedness under our revolving credit facility and/or accounts receivables facility to fund operations and up to $161.6 million to fund acquisitions, subject to certain limitations. Our amortization requirements of the term loan are: $0.8 million due each calendar quarter ending June 2003 through June 30, 2009, $159.0 million due on September 30, 2009 and $68.3 million due on December 31, 2009 in the final year of the seven and one-half year life of the term loan. If we secure commitments for and utilize our $125 million of incremental term loan capacity, it will likely mature after the term loan and be similarly back-ended in its amortization, although we cannot be certain. In the first quarter of 2003, the Company completed the acquisition of HammerBlow Acquisition Corp. ("HammerBlow") and Highland Group Industries ("Highland"). The Company made an initial $9.0 million investment in HammerBlow in November 2002. The incremental combined acquisition price for HammerBlow and Highland of approximately $209.7 million (before realization of proceeds from completed asset sales) was funded with $63.3 million of net proceeds from the issuance of our senior subordinated notes, $30.0 million of cash equity received from Heartland, the issuance of a $7.5 million deferred note payable, and the balance satisfied with borrowings under our revolving credit agreement and accounts receivable securitization facility. On May 9, 2003, the Company completed the acquisition of an automotive manufacturing business from Metaldyne for approximately $22.7 million on a debt-free basis. The acquired business is a leading manufacturer of specialized fittings and cold-headed parts used in automotive and industrial applications. The transaction was funded by a combination of borrowings under the Company's revolving credit facility and a cash equity contribution by Heartland. The acquired business had 2002 revenues of approximately $16.7 million. We have other cash commitments related to leases. We have engaged in a number of sale-leaseback transactions. In January 2002, we entered into sale-leaseback transactions with respect to nine real properties for gross proceeds of approximately $20.9 million, which were used to repay advances from Metaldyne. Metaldyne guaranteed all of the leases which resulted in the leases being accounted for as capital leases. In connection with the June 2002 transactions, Metaldyne was released from its guarantee. Letters of credit with a face amount of approximately $13.3 million were subsequently issued under our credit facility with respect to our obligations under these leasing transactions. As a result of the removal of the Metaldyne guarantee, we account for these lease transactions as operating leases and we eliminated the capitalized lease obligation and related capitalized lease assets previously recorded. Annualized rent expense related to these lease transactions is approximately $2.5 million. During the year ended December 31, 2002, we entered into operating leases for three additional facilities. Annual rent expense related to these lease transactions is approximately $1.5 million. During the fourth quarter we also entered into sale-leaseback transactions with respect to certain manufacturing equipment. We realized proceeds of approximately $5.7 million. Annual rent expense related to these transactions is approximately $0.9 million. In March 2003, the Company completed a sale and lease back of certain personal property that resulted in net cash 29

proceeds of approximately $28.0 million. The proceeds were used to repay outstanding balances under the Company's revolving credit facility. Annual rent expense related to this lease transaction will approximate $4.4 million. In March, 2003 we also completed the sale and subsequent leaseback with respect to two real properties for gross proceeds of approximately $7.8 million. Annual rent expense related to these transactions will approximate $0.9 million. In June 2003, the Company completed another sale and subsequent lease back of certain personal property that resulted in net cash proceeds of approximately $25.9 million. The proceeds were used to reduce debt levels. Annual rent expense related to these lease transactions will approximate $4.0 million. In connection with the Fittings acquisition, we agreed to sublease from Metaldyne the facility where the acquired business is currently located. Annual rent expense related to this sublease is expected to be $0.2 million. We expect to continue to utilize leasing as a financing strategy in the future to meet capital expenditure needs and to reduce debt levels. In addition to the foregoing contractual commitments, we have also agreed to assume certain obligations resulting from the November 2000 acquisition of Metaldyne by Heartland. At that time, Metaldyne made restricted stock grants to employees with terms that allow eligible employees to elect to receive cash at stipulated amounts in lieu of shares as the restricted stock grants vest. We have agreed to be responsible for the cash costs of those elections to the extent they relate to our current and former employees or allocable to current and former Metaldyne corporate level employees in accordance with the agreement. Under these arrangements, the approximate stipulated dollar value of the shares for which we are responsible that have vested or will vest, are as follows: $4.2 million on January 14, 2002, $7.6 million on January 14, 2003 and $8.5 million on January 14, 2004. To the extent that cash elections are not made, the employees will be entitled to retain their shares in Metaldyne, but we may decide at any time to work with Metaldyne to replace all or a portion of the restricted stock grants and related obligations at Metaldyne with new restricted stock grants and similar obligations. Based on our capital structure and the geographic areas in which we operate, we are subject to market risk due to changes in interest rates and fluctuations in the value of foreign currencies. We do not currently use derivative financial instruments to manage these risks. Our exposure to interest rate risk results from the floating rates on our $335.0 million senior term loan and our $150 million revolving credit facility, under which we had $332.9 million outstanding under the senior term loan and no amounts outstanding under the revolving credit facility at June 30, 2003. Borrowings under our credit facility bear interest, at various rates, as more fully described in Note 9 to the accompanying financial statements as of June 30, 2003. Based on current amounts outstanding, a 1% increase or decrease in the per annum interest rate for the term loan and revolving credit facility would change interest expense by $3.3 million annually. We conduct business in several locations throughout the world and are exposed to market risk from changes in the value of foreign currencies. The functional currencies of our foreign subsidiaries are generally the local currency in the country of domicile. We manage these operating activities at the local level and revenues and costs are generally denominated in such local currencies. As a result of the financing transactions entered into on June 6, 2002, the additional issuance of $85 million aggregate principal amount of senior subordinated notes, and recent acquisitions, we are highly leveraged. In addition to normal capital expenditures, we may incur significant amounts of additional debt and further burden cash flow in pursuit of our internal growth and acquisition strategies. The terms of our credit facility as amended and restated require the Company and its subsidiaries to meet certain restrictive financial covenants and ratios computed quarterly, including a leverage ratio (total consolidated indebtedness plus outstanding amounts under the accounts receivable securitization facility over consolidated EBITDA, as defined), interest expense ratio (EBITDA over cash interest expense, as defined) and a capital expenditures covenant, the most restrictive of which is the leverage ratio. Our permitted leverage ratio was 5.25 to 1.00 at June 30, 2003. The permitted leverage ratio becomes more restrictive in future periods, declining to 4.75 to 1.00 at December 31, 2003, 4.00 to 1.00 at December 31, 2004 and 3.25 to 1.00 at December 31, 2005 and thereafter. The Company was in compliance with its covenants at June 30, 2003. We believe that our liquidity and capital resources, including anticipated cash flows from operations, will be sufficient to meet debt service, capital expenditure and other short-term and long-term obligations needs for the foreseeable future, but we are subject to unforeseeable events and risks. 30

OFF-BALANCE SHEET ARRANGEMENTS In connection with the transactions, we entered into an agreement to sell, on an ongoing basis, the trade accounts receivable of certain business operations to a wholly-owned, bankruptcy-remote, special purpose subsidiary, TSPC, Inc. ("TSPC"). TSPC, subject to certain conditions, may from time to time sell an undivided fractional ownership interest in the pool of domestic receivables, up to approximately $125 million, to a third party multi-seller receivables funding company, or conduit. Upon sale of receivables, the Company retains a subordinated interest in the receivables. Under the terms of the agreement, new receivables can be added to the pool as collections reduce previously sold receivables. The facility is anticipated to be an important source of liquidity in 2003 and subsequent years. At June 30, 2003, we had no amounts outstanding and $61.6 million available under the facility. The facility is subject to customary termination events, including, but not limited to, breach of representations or warranties, the existence of any event that materially adversely affects the collectibility of receivables or performance by a seller and certain events of bankruptcy or insolvency. The proceeds of sale are less than the face amount of accounts receivable sold by an amount that approximates the purchaser's financing costs. The agreement expires on June 6, 2005. If we are unable to renew or replace this facility, it could materially adversely affect our liquidity. CASH OBLIGATIONS Under various agreements, we are obligated to make future cash payments in fixed amounts. These include payments under our long-term debt agreements, rent payments required under operating lease agreements for 15 facilities and certain capital equipment, severance obligations related to our cost savings plans and our allocable share of certain compensation and benefit obligations due to Metaldyne. The following table summarizes our expected fixed cash obligations over various future periods related to these items. PAYMENTS DUE BY PERIODS (IN MILLIONS) --------------------------------------------------------------- LESS THAN 1 - 3 4 - 5 AFTER TOTAL ONE YEAR YEARS YEARS 5 YEARS --------- ---------- -------- -------- --------- Contractual cash obligations: Long-term debt.......................................... $ 779.2 $ 11.4 $ 6.9 $ 6.6 $ 754.3 Lease obligations....................................... 130.9 13.4 29.9 21.0 66.6 Restricted stock obligations............................ 8.5 8.5 -- -- -- Severance............................................... 8.3 3.5 .9 0.6 3.3 -------- ---------- -------- -------- --------- Total contractual obligations............................. $ 926.9 $ 36.8 $ 37.7 $ 28.2 $ 824.2 ======== ========== ======== ======== ========= As of June 30, 2003, we are contingently liable for stand-by letters of credit totaling $23.7 million issued on our behalf by financial institutions under our revolving credit facility. These letters of credit are used for a variety of purposes, including certain operating leases and meeting various states' requirements in order to self-insure workers' compensation claims, including incurred but not reported claims. CRITICAL ACCOUNTING POLICIES The following discussion of accounting policies is intended to supplement the accounting policies presented in Note 3 to our 2002 audited financial statements. The expenses and accrued liabilities or allowances related to certain of these policies are based on our best estimates at the time of original entry in our accounting records. Adjustments are recorded when actual experience differs from the expected experience underlying the estimates. We make frequent comparisons of actual versus expected experience to mitigate the likelihood of material adjustments. Accounting Basis for Transactions. Prior to June 6, 2002, we were owned by Metaldyne. On November 28, 2000, Metaldyne was acquired by an investor group led by Heartland. The pre-acquisition basis of accounting 31

for periods prior to November 28, 2000 is reflected on the historical basis of accounting and all periods subsequent to November 28, 2000 are reflected on a purchase accounting basis and are therefore not comparable. On June 6, 2002, Metaldyne issued approximately 66% of our fully diluted common stock to an investor group led by Heartland. As a result of the transactions, we did not establish a new basis of accounting as Heartland is our and Metaldyne's controlling shareholder and the transactions were accounted for as a reorganization of entities under common control. Our combined financial information includes allocations and estimates of direct and indirect Metaldyne corporate administrative costs attributable to us, which are deemed by management to be reasonable but are not necessarily reflective of those costs to us on an ongoing basis. Receivables. Receivables are presented net of allowances for doubtful accounts. We monitor our exposure for credit losses and maintain adequate allowances for doubtful accounts. We do not believe that significant credit risk exists. Trade accounts receivable of substantially all domestic business operations may be sold, on an ongoing basis, to TSPC, Inc., a wholly owned subsidiary of the Company. Depreciation and Amortization. Depreciation is computed principally using the straight-line method over the estimated useful lives of the assets. Annual depreciation rates are as follows: buildings and buildings/land improvements, 2.5% to 10% and machinery and equipment, 6.7% to 33.3%. Capitalized debt issuance costs are amortized over the underlying terms of the related debt securities. Customer relationship intangibles are amortized over periods ranging from 6-40 years, trademarks/trade names are amortized over a 40-year period, while technology and other intangibles are amortized over periods ranging from 5-30 years. Excess of Cost over Net Assets of Acquired Companies and Other Intangibles. The Company tests goodwill for impairment on an annual basis, unless a change in business conditions occurs which requires a more frequent evaluation, by comparison of estimated fair value to carrying value. In assessing the recoverability of goodwill, the Company estimates fair value using the present value of expected future cash flows and other valuation measures. The Company also tests its other intangibles for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that their carrying amount may not be recoverable. The factors considered by management in performing this assessment include current operating results, business prospects, market trends, potential product obsolescence, competitive activities and other economic factors. Pension and Postretirement Benefits Other than Pensions. Annual net periodic expense and benefit liabilities under our defined benefit plans are determined on an actuarial basis. Assumptions used in the actuarial calculations have a significant impact on plan obligations and expense. Annually, we review the actual experience compared to the more significant assumptions used and make adjustments to the assumptions, if warranted. The healthcare trend rates are reviewed with the actuaries based upon the results of their review of claims experience. Discount rates are based upon an expected benefit payments duration analysis and the equivalent average yield rate for high-quality fixed-income investments. Pension benefits are funded through deposits with trustees and the expected long-term rate of return on fund assets is based upon actual historical returns modified for known changes in the market and any expected change in investment policy. Postretirement benefits are not funded and our policy is to pay these benefits as they become due. Certain accounting guidance, including the guidance applicable to pensions, does not require immediate recognition or the effects of a deviation between actual and assumed experience or the revision of an estimate. This approach allows the favorable and unfavorable effects that fall within an acceptable range to be netted. Other Loss Reserves. We have numerous other loss exposures, such as environmental claims, product liability, litigation, realizability of deferred tax assets, and accounts receivable. Establishing loss reserves for these matters requires the use of estimates and judgment in regard to risk exposure and ultimate liability. We estimate losses under the programs using consistent and appropriate methods; however, changes to our assumptions could materially affect our recorded liabilities for loss. Where available, we utilize published credit ratings for our debtors to assist us in determining the amount of required reserves. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK In the normal course of business, we are exposed to market risk associated with fluctuations in foreign exchange rates. We are also subject to interest risk as it relates to long-term debt. See Item 2, "Management's 32

Discussion and Analysis of Financial Condition and Results of Operations" for details about our primary market risks, and the objectives and strategies used to manage these risks. ITEM 4. CONTROLS AND PROCEDURES (a) An evaluation was carried out by management with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) pursuant to Rule 13a-15 of the Exchange Act. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, except as described in (b) below, as of the end of the period covered by this report, our disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms. (b) During the last fiscal quarter to which this report relates, we have initiated corrective actions to address two material control weaknesses previously disclosed that have materially improved and are reasonably likely to materially improve our internal control over financial reporting. The material weaknesses identified relate to internal accounting controls over: (1) the Company's closing, consolidation and financial monitoring processes, and; (2) use of standardized accounting policies and procedures appropriate to each business unit's activities. The corrective actions implemented include hiring additional financial management staff to: (1) implement closing and consolidation process improvements, including performance of additional monitoring activities and more timely preparation of account reconciliations; and (2) formally document and communicate the application and use of the Company's critical accounting policies and related procedures to appropriate business unit financial personnel. 33

PART II. OTHER INFORMATION TRIMAS CORPORATION ITEM 1. LEGAL PROCEEDINGS. A civil suit was filed in the United States District Court for the Central District of California in April 1983 by the United States of America and the State of California under the Federal Superfund law against over 30 defendants, including a subsidiary of ours, for alleged release into the environment of hazardous substances disposed of at the Stringfellow Disposal Site in California. The plaintiffs have requested, among other things, that the defendants clean up the contamination at that site. A consent decree has been entered into by the plaintiffs and the defendants, including us, providing that the consenting parties perform partial remediation at the site. The State of California has agreed to take over clean-up of the site, as well as responsibility for governmental entities' past response costs. We estimate that we will have no share of the clean-up expense at this site. The plaintiffs had sought other relief such as reimbursement of response costs and injunctive relief from the defendants under CERCLA and other similar state law theories, but the consent decree governs the remedy. Additionally, we and approximately 60 other entities including the State were defendants in a toxic tort suit brought in the Superior Court of the State of California in May 1998 by various persons residing in the area of the site and seeking damages for alleged personal injuries claimed to arise from exposure to contaminants from the site. The Superior Court of the State of California has issued an order dismissing all plaintiffs in the action. A final judgment dismissing the matter without any recovery by plaintiffs was entered by the court on July 23, 2003. Another civil suit was filed in the United States District Court for the Central District of California in December 1988 by the United States of America and the State against more than 180 defendants, including us, for alleged release into the environment of hazardous substances disposed of at the Operating Industries, Inc. site in California. This site served for many years as a depository for municipal and industrial waste. The plaintiffs have requested, among other things, that the defendants clean up the contamination at that site. Consent decrees have been entered into by the plaintiffs and a group of the defendants, including us, providing that the consenting parties perform certain remedial work at the site and reimburse the plaintiffs for certain past costs incurred by the plaintiffs at the site. We estimate that our share of the clean-up will not exceed $450,000, for which we have received insurance proceeds. Plaintiffs had sought other relief such as damages arising out of claims for negligence, trespass, public and private nuisance, and other causes of action, but the consent decree governs the remedy. While based upon our present knowledge and subject to future legal and factual developments, we do not believe that any of these litigations will have a material adverse effect on our consolidated financial position, results of operations or cash flow, future legal and factual developments may result in materially adverse expenditures. As of August 6, 2003, we were a party to approximately 612 pending cases involving an aggregate of approximately 30,427 claimants alleging personal injury from exposure to asbestos containing materials formerly used in gaskets (both encapsulated and otherwise) manufactured or distributed by certain of our subsidiaries for use in the petrochemical refining and exploration industries. In addition, we acquired various companies to distribute our products that had distributed gaskets of other manufacturers prior to acquisition. We believe that many of our pending cases relate to locations at which none of our gaskets were distributed or used. Total settlement costs (exclusive of defense costs) for all such cases, some of which were filed over 12 years ago, have been approximately $2.3 million. We do not have significant primary insurance to cover our settlement and defense costs. We believe that there may be excess insurance policies of former owners available to us that we are in the process of reconstructing, but such insurance may not be available. Based upon our experience to date and other available information, we do not believe that these cases will have a material adverse effect on our financial condition or future results of operations. However, we may be subjected to significant additional claims in the future, the cost of settling cases in which product identification can be made may increase, and we may be subjected to further claims in respect of the former activities of our acquired gasket distributors. We are subject to other claims and litigation in the ordinary course of our business, but do not believe that any such claim or litigation will have a material adverse effect on our financial position or results of operations. 34

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS. None of our securities, which were not registered under the Securities Act, have been issued or sold by us since December 31, 2002 except as follows: 1. On January 30, 2003, we issued 700,000 shares of common stock to Heartland at a price of $20.00 per share or an aggregate price of $14,000,000. 2. On February 21, 2003, we issued 800,000 shares of common stock to Heartland at a price of $20.00 per share or an aggregate price of $16,000,000. 3. On May 9, 2003, we issued 250,000 shares of common stock to Heartland at a price of $20.00 per share or an aggregate amount of $5,000,000. The issuance of the securities described above was exempt from registration under the Securities Act in reliance on Section 4(2) of such Securities Act as transactions by an issuer not involving any public offering. The recipients of securities in each such transaction represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the share certificates issued in such transactions. All recipients had adequate access to information about us at the time of their investment decision. ITEMS 3, 4 AND 5. Not applicable. ITEM 6.

(b) Pension Plans. (i) Effective as of December 31, 2002, except for Employees included in the United Auto Workers Hi-Vol Livonia collective bargaining group (the "UNION EMPLOYEES") who participate in the MascoTech, Inc. Master Hourly Employees Pension Plan (the "UNION PLAN"), the Transferred Employees have ceased to participate in, or accrue any further benefits under, any tax-qualified defined benefit plan of Sellers or their Subsidiaries; provided, however, that, to the extent permitted by applicable law, and, except as otherwise elected in subsection (ii) below, the benefits of the Union Employees in the Union Plan shall be increased by crediting the service of such Transferred Employees with Buyer and its Subsidiaries through the earlier of (A) December 31, 2003 and (B) the Plan Effective Date (as defined below). Effective as of the Effective Time, except as otherwise provided herein, Buyer shall not have any responsibility for contributing to or under any tax-qualified defined benefit plan maintained by Sellers or their Subsidiaries. Except as otherwise provided below, all assets and liabilities of any tax-qualified defined benefit plan maintained by Sellers or any of their Subsidiaries attributable to any Employee or Former Employee of the Acquired Business shall be retained by Sellers. Notwithstanding the foregoing, if (A) on or before December 31, 2003, Buyer enters into a binding collective bargaining agreement (the "UNION AGREEMENT") with respect to the Union Employees; (B) such Union Agreement provides for the Union Employees to participate in a defined benefit pension plan sponsored by Buyer or its Subsidiaries (the "BUYER UNION PLAN"); and (C) the Buyer Union Plan credits service with Sellers for purposes of determining benefit accruals for Union Employees, then the following subsections (ii), (iii), (iv) and (v) shall apply. (ii) Buyer shall, as soon as practicable after entering into the Union Agreement, notify Metaldyne thereof and advise Metaldyne as to whether the Union Agreement meets the requirements set forth in the last sentence of Section 7.6(b)(i) and, if applicable, of the date that is the Plan Effective Date. Buyer shall establish or maintain, as of the date the Buyer Union Plan or any other replacement plan becomes effective pursuant to the collective bargaining agreement with the Employees (the "PLAN EFFECTIVE DATE"), a tax-qualified defined benefit plan (the "BUYER'S PENSION PLAN") for Employees and Former Employees participating in the Union Plan. Subject to the transfer of assets described in Section 7.6(b)(iii), the Buyer's Pension Plan shall assume the liabilities as of the Plan Effective Date for the benefits of all Employees and Former Employees participating in the Union Plan. (iii) On a day which is within 60 days after the later of (i) the date upon which the Buyer delivers to Metaldyne notice that the Buyer's actuaries, pursuant to Section 7.6(b)(v) hereof, have reviewed the calculations of Sellers' actuaries and are satisfied that such calculations are in accordance with this Agreement (or have failed to do so within the 60 day period provided for in Section 7.6(b)(v)), or (ii) the day upon which the Buyer delivers to Metaldyne a favorable IRS determination letter or an opinion of the Buyer's counsel, reasonably satisfactory to Metaldyne's counsel, to the effect that the terms of the Buyer's Pension Plan and its related trust qualify, as to form, under Section 401(a) and Section 501(a) of the Code, Sellers shall cause the trustee under the Union Plan ("SELLERS' TRUSTEE") to transfer to the trustee of the Buyer's Pension Plan (the "BUYER'S TRUSTEE") cash assets or such other assets agreeable to the Buyer's Trustee and Sellers' Trustee in an amount equal to the amount necessary to satisfy the applicable requirements of Sections 414(1) and 401(a)(12) of the Code, computed based on the actuarial assumptions used by Sellers for financial disclosure purposes for the most recently completed fiscal year ending on or before the date of such transfer. (iv) The amount transferred pursuant to Section 7.6(b)(iii) shall be adjusted for investment earnings or losses of the trust in which the Union Plan assets are held for the period between the Plan Effective Date and the actual date of transfer and reduced by the amount of any benefit payments actually paid from such plan to Employees and Former Employees during such period and a proportionate share of administrative expenses for such period if such administrative expenses are properly chargeable (and are actually charged) to the Union Plan. Sellers shall estimate such earnings as of the actual date of transfer and then within 90 days of the actual date of transfer, Sellers shall cause Sellers' Trustee to remit to the -18-

Company's Trustee or the Buyer shall cause the Buyer's Trustee to remit to Sellers' Trustee, as appropriate, an amount equal to the difference between the actual rate of earnings for such period and the estimated amount transferred as of the actual date of transfer (such difference to be adjusted for investment earnings at the State Street Bank short-term rate for the period between the actual date of transfer and the date such difference is paid to Sellers' Trustee or the Buyer's Trustee). Notwithstanding anything in this Section 7.6(b) to the contrary, following the Plan Effective Date and until the date of the respective transfers of assets to trusts under the Buyer's Pension Plan, Sellers shall cause Sellers' Trustee to continue to provide benefits to plan participants in accordance with the terms of the Union Plan to the extent that such benefits have accrued on or before the Plan Effective Date. To the extent that benefits have accrued after the Plan Effective Date, following the transfer of assets pursuant to Section 7.6(b)(iii), the Buyer shall pay such benefits to plan participants (retroactively, if applicable) in accordance with the terms of the Buyer's Pension Plan. (v) The assets caused to be transferred pursuant to Section 7.6(b)(iii) shall be calculated by Sellers' actuary, and shall be subject to review by the Buyer's actuary for the purpose of confirming that the calculation was made in accordance with (i) the actuarial assumptions and methods set forth in this Section 7.6(b) and (ii) generally accepted actuarial practice. As soon as practicable after receiving the notification from Buyer referred to in Section 7.6(b)(ii), Sellers shall provide the Buyer with a detailed summary of the calculations described in this Section 7.6(b) and any back-up data reasonably requested by Buyer. If the Buyer or the Buyer's actuary do not notify Metaldyne to the contrary within 60 days after the delivery to Buyer of such detailed summary and data, the calculations of Sellers' actuary pursuant to this Section 7.6(b) shall be deemed to be final, conclusive and binding on the parties. If, however, Buyer notifies Metaldyne in writing within such period that it and its actuary believe that the calculations were not prepared in accordance with the requirements of this Section 7.6(b) and such notice specifies (i) the precise items of the calculations challenged, (ii) the basis of the challenge and (iii) the amount of the adjustment they propose with respect to each such item, the parties will then attempt to resolve their differences with respect thereto. If the parties are unable to resolve their dispute within 30 days after the date the Buyer notifies Metaldyne of the disputed items, the disputed items shall be referred to an international benefits consulting firm (the "ACTUARY FIRM") mutually acceptable to Buyer and Sellers. Sellers and Buyer shall request that the Actuary Firm resolve such disputes and report to Sellers and Buyer upon such remaining disputed items within 45 days after such referral. The decision of the Actuary Firm shall be final, conclusive and binding on the parties hereto. The fees and expenses of the Actuary Firm in conducting this assignment shall be borne equally by Sellers on the one hand and Buyer on the other. (c) Defined Contribution Plan. As soon as practical after the Closing Date, Sellers shall cause the trustee of Sellers' defined contribution plans listed on Schedule 7.6(c) hereof ("SELLERS' SAVINGS PLANS") to transfer all of the assets and liabilities thereof attributable to Employees and Former Employees of the Acquired Business to one or more defined contribution plans maintained by Buyer. Unless otherwise agreed by Sellers and Buyer, the assets to be transferred shall be cash and promissory notes for loans made to Employees and Former Employees of Buyer under the terms of the Sellers' Savings Plans. Sellers shall be responsible for making contributions to Sellers' Savings Plans for Employees and Former Employees for all periods prior to the Effective Time but not thereafter. (d) Severance and Other Liability. Buyer shall pay an amount to Sellers equal to the sum of (i) the excess of the "accumulated benefit obligation" of each of the MascoTech, Inc. Pension Plan and MascoTech, Inc. Master Hourly Employees Pension Plan attributable to Employees and Former Employees, over the amount of assets of each such plan attributable to Employees and Former Employees, all calculated as of the Effective Time, and (ii) the FAS 87 service cost resulting from Sellers' agreement to credit additional service and compensation set forth in Section 7.6(b)(i) hereof (determined using the actuarial assumptions and methods utilized by Sellers in determining the service cost for such plans). Such "accumu- -19-

lated benefit obligation" for each such plan shall be computed using a discount rate of 6.75%, compounded annually and the other actuarial assumptions and methods utilized by Sellers in determining the "accumulated benefit obligation" of such plans for FAS 87 purposes as of the Effective Time. The amount of plan assets allocable to the Employees and Former Employees shall be determined by multiplying the actual fair market value of the assets of each plan at the Effective Time by a fraction, the numerator of which is the "accumulated benefit obligation" (determined as set forth above) of the applicable plan attributable to the Employees and Former Employees (the "BUYER'S ABO"), and the denominator of which is the sum of the Buyer's ABO and the "projected benefit obligation" (computed using a discount rate of 6.75%, compounded annually and the other actuarial assumptions and methods utilized by Seller in determining the "projected benefit obligation" of such plans for FAS 87 purposes as of the Effective Time) attributable to participants and former participants in the plan other than the Employees and Former Employees. The computations shall be made by Sellers' actuary, and they shall be subject to review in accordance with the procedure set forth in Section 7.6(b)(v) above. Following final agreement on the calculations described herein, Sellers shall remit to the Buyer or the Buyer shall remit to Sellers, as appropriate, an amount equal to the difference between the actual amount owed and the estimated amount transferred as of Closing Date (such difference to be adjusted for investment earnings at the State Street Bank short-term rate for the period between the Closing Date and the date such difference is paid to Seller or Buyer). (e) Worker's Compensation Claims. The Buyer shall assume liability for all suits, claims, proceedings and actions pending as of or commenced after the Effective Time resulting from actual or alleged harm or injury to Employees or Former Employees regardless of when the incident or accident giving rise to such liability occurred or occurs. Buyer shall make all necessary arrangements to assume all worker's compensation claim files, whether open or closed, as of the Effective Time, and Buyer shall make the necessary arrangements for assuming the continued management of such liabilities. (f) Welfare Benefit Plans. (i) Coverage for all Transferred Employees and Former Employees (the "COVERED EMPLOYEES") and their respective eligible dependents under the welfare benefit plans (as defined in Section 3(1) of ERISA) maintained by the Sellers or their Affiliates for the benefit of Employees prior to the Closing Date (the "SELLER WELFARE PLANS") shall terminate effective as of the Effective Time. Subject to the satisfaction of any conditions, limitations or waiting periods referred to in subsection (ii) below, the welfare benefit plans (as defined in Section 3(1) of ERISA) maintained by Buyer or its Affiliates (the "BUYER WELFARE PLANS") shall provide coverage and benefits to such Covered Employees (and the eligible dependents of such Covered Employees) in substantially the same manner as provided by seller prior to the Effective Time. The Seller Welfare Plans shall be liable only for claims incurred prior to the Effective Time, and the Buyer shall be liable for any claims incurred by Covered Employees (and the eligible dependents of such Covered Employees) after the Effective Time. The Covered Employees shall be entitled to apply deductibles and out of pocket payments expended for covered medical and dental expenses under the Seller Welfare Plans in the plan fiscal year ending December 31, 2003, to the deductibles and out of pocket maximums under the Buyer Welfare Plans, if any, for the plan fiscal year which ends on December 31, 2003. If requested by the Buyer, the Sellers shall furnish the Buyer with a schedule setting forth the deductibles and out of pocket maximums for each Covered Employee. The Seller Welfare Plans shall be liable only for claims incurred prior to or as of the Effective Time, and the Sellers shall be liable for any claims incurred by Covered Employees (and the eligible dependents of such Covered Employees) under the Buyer Welfare Plans after the Effective Time. (ii) No pre-existing condition limitations, exclusions or waiting periods applicable with respect to life and accident death and dismemberment insurance, disability, sickness and accident and medical benefits under the Buyer Welfare Plan shall apply to the Covered Employees to the extent that such limitations, exclusions or waiting periods exceed those in effect under the Seller Welfare Plans as of the Effective Time. -20-

(g) To the extent that Buyer or Sellers are unable to, with reasonably diligent effort and at reasonable expense, perform their obligations in the manner contemplated by this Section 7.6, Buyer and Sellers shall cooperate in order to achieve the most economic transfer reasonably practicable and Buyer on the one hand and Sellers on the other agree to indemnify each other for any incremental expenses incurred by the other as a result of any accommodation by either such party from the respective responsibilities assigned to the parties by this Section 7.6. SECTION 7.7. INFORMATION; COOPERATION. If after the Closing, in order properly to prepare documents or reports required to be filed with Governmental Authorities or financial statements, it is necessary that Buyer or Sellers be furnished with additional information relating to the Acquired Business and such information is in possession of any party hereto, such party will use its reasonable efforts to furnish, or cause to be furnished, such information to the party requesting information. SECTION 7.8. FURTHER ASSURANCES. In case at any time after the Closing Date any further action is necessary or desirable to fully and effectively transfer the benefits of the Purchased Assets to Buyer and to fully and effectively provide for the assumption of the Assumed Liabilities by Buyer or otherwise to carry out the purposes of this Agreement, the proper officers and directors of Buyer and Sellers shall execute such further documents (including assignments, acknowledgments and consents and other instruments of transfer) and shall take and cause their respective employees and agents to take such further actions as may be necessary or desirable in order to carry out the intent of this Agreement.

In the event of a fire or other casualty affecting the Premises, or of a taking of all or a part of the Building or Premises under the power of eminent domain, Landlord shall not exercise any right which may have the effect of terminating the Prime Lease without first obtaining the prior written consent of Tenant. In the event Landlord is entitled, under the Prime Lease, to a rent abatement as a result of a fire or other casualty or as a result of a taking under the power of eminent domain, then Tenant shall be entitled to such rent abatement. If the Prime Lease imposes on Landlord the obligation to repair or restore leasehold improvements or alterations, Tenant shall be responsible for the repair or restoration of such leasehold improvements or alterations. 15. ALTERATIONS. Tenant may make any alterations in or additions or improvements to the Premises ("ALTERATIONS"), but only after obtaining Landlord's and Prime Landlord's written consent if and to the extent such consent is required to be obtained by Landlord under the Prime Lease. Tenant shall make Alterations in compliance with all of the covenants of Landlord contained in the Prime Lease pertaining to the performance of such Alterations. In addition, Tenant shall indemnify, defend and hold harmless Landlord against liability, loss, cost, damage, liens and expense imposed on Landlord arising out of the performance of Alterations by Tenant. 16. SURRENDER. Upon the expiration of this Sublease, or upon the termination of the Sublease or of the Tenant's right to possession of the Premises, Tenant will at once surrender and deliver up the Premises, together with all improvements thereon, only to the extent required under the Prime Lease, to Landlord in the condition required under the Prime Lease and pursuant to the requirements of the Prime Lease, including the removal of any alterations made by Landlord or Tenant, to the extent Prime Landlord requires their removal. 17. REMOVAL OF TENANT'S PROPERTY. Upon the expiration of this Sublease, Tenant shall remove Tenant's articles of personal property incident to Tenant's business ("TRADE FIXTURES"); provided, however, that Tenant shall repair any injury or damage to the Premises which may result from such removal, and shall restore the Premises to the same condition as prior to the installation thereof. If Tenant does not remove Tenant's Trade Fixtures from the Premises prior to the expiration or earlier termination of the Term, Landlord may, at its option, remove the same (and repair any damage occasioned thereby and restore the Premises as aforesaid) and dispose thereof or deliver the same to any other place of business of Tenant, or warehouse the same, and Tenant shall pay the cost of such removal, repair, restoration, delivery or warehousing to Landlord on demand, or Landlord may treat said Trade Fixtures as having been conveyed to Landlord with this Sublease as a bill of sale, without further payment or credit by Landlord to Tenant. 18. HOLDING OVER. Tenant shall have no right to occupy the Premises or any portion thereof after the expiration of this Sublease or after termination of this Sublease or of Tenant's right to possession in consequence of an Event of Default hereunder. In the event Tenant or any party claiming by, through or under Tenant holds over, thereafter the tenancy shall be from month to month in the absence of a written agreement to the contrary, and Tenant shall pay to Prime Landlord a daily occupancy charge equal to five percent (5%) of the Basic Rental (as defined in the Prime Lease) for the last lease year (plus all other charges payable by Tenant under this Sublease) from each -4-

day from the expiration or termination of this Sublease until the date the Premises are delivered in the condition required herein, and Landlord's right to damages for such illegal occupancy shall survive 19. ENCUMBERING TITLE. Tenant shall not do any act which shall in any way encumber the title of Prime Landlord in and to the Premises, nor shall the interest or estate of Prime Landlord or Landlord be in any way subject to any claim by way of lien or encumbrance, whether by operation of law, by virtue of any express or implied contract by Tenant or by reason of any other act or omission of Tenant. Any claim to, or lien upon the Premises arising from any act or omission of Tenant shall accrue only against the subleasehold estate of Tenant and shall be subject and subordinate to the paramount title and rights of Prime Landlord in and to the Premises and the interest of Landlord in the Premises leased pursuant to the Prime Lease. Without limiting the generality of the foregoing, Tenant shall not permit the Premises to become subject to any mechanic's or other lien, charge or order for the payment of money filed against Landlord or Prime Landlord as a result of any act or omission of Tenant; provided, however, that if so permitted under the Prime Lease, Tenant shall have the right to contest in good faith and with reasonable diligence, the validity of any such lien or claimed lien; provided further, however, that Tenant shall, at its own cost and expense, cause the same to be discharged of record or bonded within thirty (30) days after written notice from Landlord or Prime Landlord to Tenant of the filing thereof; and Tenant shall indemnify and save and hold harmless Landlord, and if so required by the Prime Lease, Prime Landlord, against and from all costs, liabilities, suits, penalties, claims and demands, including reasonable attorneys' fees, resulting therefrom. 20. INDEMNITY. A. Tenant agrees to indemnify, forever save and hold Landlord and each of Landlord's agents, contractors, licensees, employees, managers, members, directors, officers, partners, trustees and invitees (collectively, the "INDEMNIFIED PARTIES;" each, an "INDEMNIFIED PARTY") harmless from and against any and all Losses which any Indemnified Party may suffer or incur arising out of or in connection with this Sublease, including, without limitation, (i) Tenant's failure to comply with the provisions of this Sublease; (ii) Tenant's or Tenant's employees' or Tenant's successors or assigns use of the Premises; (iii) the conduct of Tenant's business, any activity, work or things done, permitted or suffered by Tenant, its agents, contractors, licensees, employees, directors, officers, partners, trustees, successors or assigns (other than work performed by Landlord) in or about the Premises or the Building (as defined in the Prime Lease); (iv) Tenant's employees nonobservance or nonperformance or any statute, law, ordinance, rule or regulation; (v) any negligence or other wrongful act or omission on the part of Tenant or any of its agents, contractors, licensees, employees, directors, officers, partners, trustees, successors or assigns or (vii) any accident, injury or damage to any person or property occurring in, on or about the Premises or any part thereof during the Term of this Sublease, except to the extent caused by the negligence or willful misconduct of any Indemnified Party. B. Landlord agrees to indemnify, forever save and hold Tenant and each of Tenant's agents, contractors, licensees, employees, managers, members, directors, officers, partners, trustees and invitees (collectively, the "TENANT INDEMNIFIED PARTIES;" each, a "TENANT INDEMNIFIED PARTY") harmless from and against any and all Losses which any Tenant Indemnified Party may suffer or incur arising out of, (i) Landlord's failure to comply with the provisions of this Sublease; (ii) Landlord's employees nonobservance or nonperformance of any statute, law, ordinance, rule or regulation; (iii) any negligence or other wrongful act or omission on the part of Landlord or any of its agents, contractors, licensees, employees, directors, officers, partners, trustees, successors or assigns or (iv) any accident, injury or damage to any person or property occurring in, on or about the Premises or any part thereof during the term of this Sublease to the extent caused by the negligence or willful misconduct of Landlord (with respect to a claim against Tenant). C. The parties hereto acknowledge and agree that any claim for indemnification hereunder and the obligations owed to the Indemnified Party or the Tenant Indemnified Party, as the case may be, shall be subject to the provisions of Sections 9.2 and 9.3 of the Asset Purchase Agreement. 21. LANDLORD'S RESERVED RIGHTS. Landlord shall have the same access rights as Prime Landlord under the Prime Lease. - 5 -

22. DEFAULTS. Tenant agrees that any one or more of the following events shall be considered Events of Default as said term is used herein: A. Tenant shall be adjudged an involuntary bankrupt, or a decree or order approving, as properly filed, a petition or answer filed against Tenant asking reorganization of Tenant under the Federal bankruptcy laws as now or hereafter amended, or under the laws of any State, shall be entered, and any such decree or judgment or order shall not have been vacated or stayed or set aside within ninety (90) days from the date of the entry or granting thereof; or B.

Tenant shall default in any of the other covenants and agreements herein contained to be kept, observed and performed by Tenant, and such default shall continue for thirty (30) days after notice thereof in writing to Tenant, and Tenant shall not within such 30-day period commence with due diligence and dispatch the curing of such default or having so commenced, shall thereafter fail or neglect to prosecute or complete with due diligence and dispatch the curing of such default. 23. REMEDIES. Upon the occurrence of any one or more Events of Default, Landlord may exercise any remedy against Tenant which Prime Landlord may exercise for default by Landlord under the Prime Lease. 24. NOTICES AND CONSENTS.

Such copies shall be delivered by overnight commercial courier. - 6 -

25. PROVISIONS REGARDING SUBLEASE. This Sublease and all the rights of parties hereunder are subject and subordinate to the Prime Lease. Each party agrees that it will not, by its act or omission to act, cause a default under the Prime Lease. In furtherance of the foregoing, the parties hereby confirm, each to the other, that it is not practical in this Sublease agreement to enumerate all of the rights and obligations of the various parties under the Prime Lease and specifically to allocate those rights and obligations in this Sublease agreement. Accordingly, in order to afford to Tenant the benefits of this Sublease and of those provisions of the Prime Lease which by their nature are intended to benefit the party in possession of the Premises, and in order to protect Landlord against a default by Tenant which might cause a default or event of default by Landlord under the Prime Lease: A. To the extent Prime Landlord requires payment directly from Landlord and provided Tenant timely pays all Rent when and as due under this Sublease, Landlord shall pay, when and as due, any and all base rent, additional rent and other charges payable by Landlord to Prime Landlord to the extent required under the Prime Lease. B. Landlord shall promptly provide Tenant with copies of all notices received by Landlord under the Prime Lease from Prime Landlord or its mortgagee. C. Except as otherwise expressly provided for herein, during the Term hereof Tenant shall perform all affirmative covenants of Landlord under the Prime Lease and shall refrain from performing any act which is prohibited by the negative covenants of the Prime Lease. D. Landlord shall not agree to any amendment to the Prime Lease unless Landlord shall first obtain Tenant's prior written approval thereof, which approval shall not be unreasonably withheld, conditioned or delayed. E. Except as otherwise provided herein, Tenant shall be entitled to the rights of Landlord, as tenant under the Prime Lease. Without limiting the generality of the foregoing, Landlord hereby grants to Tenant the right to receive all of the services and benefits with respect to the Premises which are to be provided by Prime Landlord under the Prime Lease. Landlord shall have no duty to perform any obligations of Prime Landlord which are, by their nature, the obligation of an owner or manager of real property. For example, Landlord shall not be required to provide the services or repairs, if any, which the Prime Landlord is required to provide under the Prime Lease. Landlord shall have no responsibility for or be liable to Tenant for any default, failure or delay on the part of Prime Landlord in the performance or observance by Prime Landlord of any of its obligations under the Prime Lease, nor shall such default by Prime Landlord affect this Sublease or waive or defer the performance of any of Tenant's obligations hereunder except to the extent that such default by Prime Landlord excuses performance by Landlord, under the Prime Lease. Notwithstanding the foregoing, the parties contemplate that Prime Landlord shall, in fact, provide the services and benefits and perform its obligations under the Prime Lease and in the event of any default or failure of such provision or performance by Prime Landlord, Landlord agrees that it will, upon notice from Tenant, make demand upon, deliver notices to and request consents or approvals from Prime Landlord to provide such services or benefits and perform its obligations under the Prime Lease and, provided that Tenant specifically agrees to pay all reasonable costs and expenses of Landlord and provides Landlord with security reasonably satisfactory to Landlord to pay such costs and expenses, Landlord will take appropriate legal action to enforce the Prime Lease. F. Tenant shall have the right to exercise all renewal rights granted to Landlord under the Prime Lease. G. Landlord shall cooperate with Tenant to cause Prime Landlord to provide services required by Tenant in addition to those otherwise required to be provided by Prime Landlord under the Prime Lease. Tenant shall pay Prime Landlord's charge for such services promptly after having been billed therefor by Prime Landlord or by Landlord. 26. SECURITY DEPOSIT. A. To secure the faithful performance by Tenant of all the covenants, conditions and agreements in this Sublease set forth and contained on the part of Tenant to be fulfilled, kept, observed and performed including, but not by way of limitation, such covenants and agreements in this Sublease which become applicable upon the termination of - 7 -

the same by re-entry or otherwise, Tenant shall deposit with Landlord the Security Deposit as specified in Section 1(N) on the understanding that: (a) the Security Deposit or any portion thereof not previously applied, or from time to time, such one or more portions thereof, may be applied to the curing of any default that may then exist, without prejudice to any other remedy or remedies which Landlord may have on account thereof, and upon such application Tenant shall pay Landlord on demand the amount so applied which shall be added to the Security Deposit so the same may be restored to its original amount; (b) should the Prime Lease be assigned by Landlord, the Security Deposit or any portion thereof not previously applied may be turned over to Landlord's assignee and if the same be turned over as aforesaid, Tenant hereby releases Landlord from any and all liability with respect to the Security Deposit and/or its application or return; (c) if permitted by law, Landlord or its successor shall not be obligated to hold the Security Deposit as a separate fund, but on the contrary may commingle the same with its other funds; (d) if Tenant shall faithfully fulfill, keep, perform and observe all of the covenants, conditions and agreements in this Sublease set forth and contained on the part of Tenant to be fulfilled, kept, performed and observed, the sum deposited or the portion thereof not previously applied, shall be returned to Tenant without interest no later than thirty (30) days after the expiration of the Term of this Sublease or any renewal or extension thereof, provided Tenant has vacated the Premises and surrendered possession thereof to Landlord at the expiration of the Term or any extension or renewal thereof as provided herein; (e) in the event that Landlord terminates this Sublease or Tenant's right to possession by reason of an Event of Default by Tenant, Landlord may apply the Security Deposit against damages suffered to the date of such termination and/or may retain the Security Deposit to apply against such damages as may be suffered or shall accrue thereafter by reason of Tenant's default; and (f) in the event any bankruptcy, insolvency, reorganization or other creditor-debtor proceedings shall be instituted by or against Tenant, or its successors or assigns, the Security Deposit shall be deemed to be applied first to the payment of any Rent due Landlord for all periods prior to the institution of such proceedings, and the balance, if any, of the Security Deposit may be retained or paid to Landlord in partial liquidation of Landlord's damages. B. Notwithstanding the above, Tenant shall have the right to post a letter of credit in place of the cash security deposit required in Section 26(A) of this Sublease in the same manner as Landlord has the right to post a letter of credit rather than cash security pursuant to Section 39(c) of the Prime Lease. In addition, Tenant shall have the obligation to post a letter of credit as additional security for this Sublease in the same manner as Landlord is obligated to post additional security for the Prime Lease pursuant to Section 39(b) of the Prime Lease (except that the test shall be the Moody's and/or Standard & Poors rating of TriMas Company, LLC, the guarantor, rather than Landlord). 27. PRIME LANDLORD'S CONSENT. The parties acknowledge that, pursuant to Section 13(d) of the Prime Lease, Prime Landlord's consent to this Sublease is not required. 28. BROKERAGE. Each party warrants to the other that it has had no dealings with any broker or agent in connection with this Sublease. 29. FORCE MAJEURE. Neither Landlord nor Tenant shall be deemed in default with respect to any of the terms, covenants and conditions of this Sublease if such parties failure to timely perform same is due in whole or in part to any strike, lockout, labor trouble (whether legal or illegal), civil disorder, failure of power, restrictive governmental laws and regulations, riots, insurrections, war, shortages, accidents, casualties, acts of God, or any other cause beyond the reasonable control of such party. 30. TRIMAS GUARANTEE. As a condition to Landlord entering into the Sublease, Tenant shall obtain the unconditional guarantee of this Sublease by TriMas Company LLC in the form attached hereto as Annex 2. 31. CERTIFICATES. Each party shall, without charge, at any time and from time to time hereafter, within ten (10) days after written request of the other party, certify to the best of its knowledge by written instrument duly executed and acknowledged to any mortgagee or purchaser, or proposed mortgagee or proposed purchaser, of any other person, firm or corporation specified in such request: (a) as to whether this Sublease has been supplemented or amended, and if so, the substance and manner of such supplement or amendment; (b) as to the validity and force and effect of this Sublease, in accordance with its tenor as then continued; (c) as to the existence of any default there- - 8 -

under; (d) as to the existence of any offsets, counterclaims or defenses hereto on the part of such other party; (e) as to the commencement and expiration dates of the Term hereof and (f) as to any other matters as may reasonably be so requested. Any such certificate may be relied upon by the party requesting it and any other person, firm or corporation to whom the same may be exhibited or delivered, and the contents of such certificate shall be binding on the party executing same. - 9 -

32. MISCELLANEOUS. The laws of the State of Michigan shall govern the validity, performance, and enforcement of this Sublease. The invalidity or unenforceability of any provision of this Sublease shall not affect or impair any other provision of this Sublease or the Sublease itself. The submission of this document for examination does not constitute an offer to lease, or a reservation of or option for the Premises, and becomes effective only upon execution and delivery thereof by Landlord and Tenant. All negotiations, considerations, representations, and understandings between the parties are incorporated herein and may be modified or altered only by agreement in writing between the parties. This Sublease shall not be recorded. A memorandum of lease describing the property, giving the commencement date and term of this Sublease and renewal rights, and referring to this Sublease, may be executed and may be recorded by either party. The agreements, terms, covenants, and conditions herein shall bind and inure to the benefit of Landlord and Tenant and their respective successors and, except as otherwise provided herein, their assigns.
