Forward-looking statements include certain anticipated, believed, planned, forecasted, expected, targeted and estimated results along with TriMas’ outlook concerning future results. The words “estimates,” “expects,” “anticipates,” “projects,” “plans,” “intends,” “believes,” “forecasts,” or future or conditional verbs, such as “will,” “should,” “could,” or “may,” and variations of such words or similar expressions are intended to identify forward-looking statements. All forward-looking statements, including, without limitation, management’s examination of historical operating trends and data are based upon our current expectations and various assumptions. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them. However, there can be no assurance that management’s expectations, beliefs and projections will be achieved. These forward-looking statements are subject to numerous assumptions, risks and uncertainties and accordingly, 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 document. 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 statements to reflect events or circumstances after the date of this document 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 included in this document include general economic conditions in the markets in which we operate and industry-based factors such as: technological developments that could competitively disadvantage us, increases in our raw material, energy, and healthcare costs, our dependence on key individuals and relationships, exposure to product liability, recall and warranty claims, work stoppages at our facilities, or our customers or suppliers, risks associated with international markets, protection of or liability associated with our intellectual property, lower cost foreign manufacturers, compliance with environmental and other regulations, and competition within our industries. In addition, factors more specific to us could cause actual results to vary materially from those anticipated in the forward-looking statements included in this document such as our substantial leverage, limitations imposed by our debt instruments, our ability to successfully pursue our stated growth strategies and opportunities, including our ability to identify attractive and other strategic acquisition opportunities and to successfully integrate acquired businesses and complete actions we have identified as providing cost-saving opportunities. Safe Harbor Statement

Agenda 2006 Fourth Quarter Highlights 2006 Fourth Quarter Operating Highlights 2006 Fourth Quarter Financial Performance TriMas Capitalization Summary Q&A Appendix

2006 Fourth Quarter Highlights TriMas is a manufacturer of highly engineered products. Our defining attributes include leading market shares, strong brand names, and diversity of end markets, customers and products. TriMas had sales of $223.3 million in fourth quarter 2006, essentially flat when compared to fourth quarter 2005. TriMas had an operating loss of $99.0 million in Q4 2006, which included a $116.5 million non-cash goodwill impairment charge, as compared to an operating profit of $9.0 million in Q4 2005. Before consideration of the goodwill impairment charge, TriMas had an operating profit of $17.5 million in Q4 2006, an increase of $8.5 million compared to operating profit of $9.0 million reported in Q4 2005. In conjunction with our annual impairment test of goodwill, we recorded a $116.5 million goodwill impairment charge related to our RV & Trailer Products and Recreational Accessories business segments. This impairment charge resulted from a decrease in the implied fair value of goodwill previously allocated to these businesses due to reduced sales and profitability in 2006 compared to prior years and an overall decline in their market values. Adjusted EBITDA during the quarter was $25.7 million, representing an increase of $6.0 million, or 30.2%, as compared to Q4 2005.

2006 Fourth Quarter Highlights The improvement in Adjusted EBITDA and operating profit (before consideration of the goodwill impairment charge) between years is attributed to: Continued earnings expansion within Packaging Systems, Energy Products and Industrial Specialties. Better conversion within Recreational Accessories driven by improved material margins due to sourcing initiatives and lower variable and fixed overhead spending as a result of cost initiatives previously implemented. The fourth quarter 2006 loss from continuing operations was $117.4 million, or $(5.65) per share on a fully-diluted basis, versus a loss from continuing operations of $9.6 million, or $(0.48) per share on a fully-diluted basis, in the year ago period. The loss in the fourth quarter of 2006 included the after-tax impact of the goodwill impairment charge of $115.3 million, or $(5.55) per share on a fully-diluted basis. TriMas finished the quarter with $168.1 million of net operating working capital, or 21.1% of sales compared to $140.7 million or 18.1% of sales for the same period a year ago. Total debt and funding under our AR Securitization facility at December 31, 2006 was $754.1 million, a decrease of approximately $10.9 million from December 31, 2005.

2006 Fourth Quarter Highlights Under the Amended and Restated Credit Agreement, the Company’s Bank LTM EBITDA at December 31, 2006 was $147.8 million, which supported our lending ratios: Leverage ratio was 5.10x vs. a leverage covenant of 5.75x. Interest coverage ratio was 1.87x vs. our covenant of 1.70x. TriMas had $3.6 million in cash at quarter end and approximately $96 million in available liquidity. Sales from discontinued operations declined $5.1 million, from $25.4 million in fourth quarter 2005 to $20.3 million in fourth quarter 2006. The loss from discontinued operations, net of tax benefits recorded, was $4.5 million and $42.6 million in the fourth quarter of 2006 and 2005, respectively. Included in the 2005 amount is a net of tax impairment charge of $41.6 million, which reduced the carrying value of net assets used in discontinued operations to their estimated fair value. In December 2006, we completed the sale of our Wood Dale, Illinois and Lakewood, Ohio facilities, which were part of our industrial fastening business. In February 2007, we sold the remaining assets and liabilities of our discontinued industrial fastening business located in Frankfort, Indiana.

The Company defines “Adjusted EBITDA” as net income (loss) before cumulative effect of accounting change, interest, taxes, depreciation, amortization, non-cash asset and goodwill impairment charges and write-offs, non-cash losses on sale-leaseback of property and equipment, and write-off of equity offering costs. (2) Represents certain charges related to our consolidation, restructuring and integration activities intended to eliminate duplicative costs or achieve cost efficiencies related to integrating acquisitions or other restructurings related to expense reduction efforts. These costs and asbestos litigation defense costs are not eliminated in the determination of Company Adjusted EBITDA, however we would exclude these costs to better evaluate our underlying business performance.

Goodwill Impairment We test our recorded balance of goodwill for impairment annually as of December 31st. We estimate the fair value of our reporting units using a third-party valuation specialist and based on the present value of expected future cash flows included in the Company’s long-range plan and other valuation measures. In completing the annual Step I impairment test, the recorded carrying values of our RV & Trailer Products and Recreational Accessories operating segments exceeded their estimated fair values, requiring us to perform additional valuation work. Based on the results of this additional valuation analysis, we recorded a goodwill impairment charge of $116.5 million related to our RV & Trailer Products ($97.5 million) and Recreational Accessories ($19.0 million) operating segments. This non-cash impairment charge resulted from a decrease in the implied fair value of recorded goodwill previously allocated to these businesses due to reduced sales and profitability in 2006 compared to prior years and/or our operating plan, and overall decline in the estimated market values of these business segments.

Lease expense and non-recurring charges are included in Adjusted EBITDA and include both cash and non-cash charges related to restructuring and integration expenses. In evaluating our business, management considers and uses Adjusted EBITDA as a key indicator of financial operating performance and as a measure of cash generating capability. Management believes this measure is useful as an analytical indicator of leverage capacity and debt servicing ability, and uses it to measure financial performance as well as for planning purposes. However, Adjusted EBITDA should not be considered as an alternative to net income, cash flow from operating activities or any other measures calculated in accordance with U.S. GAAP, or as an indicator of operating performance. The definition of Adjusted EBITDA used here may differ from that used by other companies. (1) ($ in thousands) 15,760
