CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR"
PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This Quarterly Report on Form 10-Q contains forward-looking statements regarding, among other things, our prospects and business strategies. The words "may," "will," "believes," "should," "could," "plans," "expects," "anticipate," "intends," "estimates," and similar expressions (and variations thereof), identify these forward-looking statements. Although we believe that the expectations reflected in these forward-looking statements are based on reasonable assumptions, these expectations may not prove to be correct. Because these forward-looking statements are also subject to risks and uncertainties, actual results may differ materially from the expectations expressed in the forward-looking statements. Important factors that could cause actual results to differ materially from the expectations reflected in the forward-looking statements include:

- changes in automotive manufacturers' production rates and their actual and forecasted requirements for our products, including the overall highly competitive nature of the automotive parts industry, and our resultant inability to realize the sales represented by our awarded book of business which is based on anticipated pricing for the applicable program over its life, and is subject to increases or decreases due to changes in customer requirements, customer and consumer preferences, and the number of vehicles actually produced by customers;

- increases in the costs of raw materials, including our ability to successfully reduce the impact of any such cost increases through materials substitutions, cost reduction initiatives and other methods;

2

- the cyclical nature of the global vehicular industry, including the performance of the global aftermarket sector, and changes in consumer demand and prices, including longer product lives of automobile parts and the cyclicality of automotive production and sales of automobiles which include our products, and the potential negative impact on our revenues and margins from such products;

- our continued success in cost reduction and cash management programs and our ability to execute restructuring and other cost reduction plans and to realize anticipated benefits from these plans;

- general economic, business and market conditions;

- the impact of consolidation among automotive parts suppliers and customers on our ability to compete;

- operating hazards associated with our business;

- changes in distribution channels or competitive conditions in the markets and countries where we operate, including the impact of changes in distribution channels for aftermarket products on our ability to increase or maintain aftermarket sales;

- the cost and outcome of existing and any future legal proceedings, and compliance with changes in regulations, including environmental regulations;

- labor disruptions at our facilities or at any of our significant customers or suppliers;

- economic, exchange rate and political conditions in the foreign countries where we operate or sell our products;

- customer acceptance of new products;

- new technologies that reduce the demand for certain of our products or otherwise render them obsolete;

- our ability to realize our business strategy of improving operating performance;

- capital availability or costs, including changes in interest rates, market perceptions of the industries in which we operate or ratings of securities;

- changes by the Financial Accounting Standards Board or the Securities and Exchange Commission of authoritative generally accepted accounting principles or policies;

- the impact of changes in and compliance with laws and regulations, including environmental laws and regulations, and environmental liabilities in excess of the amount reserved;

- terrorism, acts of war and similar events, and their resultant impact on economic and political conditions; and

- the occurrence or non-occurrence of other circumstances beyond our control.

FINANCIAL INFORMATION

ITEM 1. FINANCIAL STATEMENTS (UNAUDITED)

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
TENNECO AUTOMOTIVE INC.

We have reviewed the accompanying consolidated balance sheet of Tenneco Automotive Inc. and consolidated subsidiaries as of June 30, 2005, and the related consolidated statements of income and comprehensive income (loss) for the three-month and six-month periods ended June 30, 2005 and 2004, and of cash flows and changes in shareholders' equity for the six-month periods ended June 30, 2005 and 2004. These interim financial statements are the responsibility of Tenneco Automotive Inc.'s management.

We conducted our review in accordance with standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to such consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Tenneco Automotive Inc. and consolidated subsidiaries as of December 31, 2004, and the related consolidated statements of income (loss), cash flows, changes in shareholders' equity and comprehensive income (loss) for the year then ended (not presented herein); and in our report dated March 8, 2005 (May 10, 2005 as to Note 4), we expressed an unqualified opinion on those consolidated financial statements (such report includes an explanatory paragraph relating to (i) a change in accounting for goodwill and intangible assets upon the adoption of Statement of Financial Accounting Standards No. 142 and (ii) a change in method of accounting for certain inventory from the last-in, first-out method ("LIFO") to the lower of cost, determined on a first-in, first-out ("FIFO") basis, or market method). In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2004 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

(UNAUDITED)

(1) As you read the accompanying financial statements and Management's Discussion and Analysis you should also read our Annual Report on Form 10-K/A for the year ended December 31, 2004.

In our opinion, the accompanying unaudited financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly Tenneco Automotive Inc.'s financial position, results of operations, cash flows, changes in shareholders' equity, and comprehensive income (loss) for the periods indicated. We have prepared the unaudited interim consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for annual financial statements.

Our consolidated financial statements include all majority-owned subsidiaries. We carry investments in 20 percent to 50 percent owned companies at cost plus equity in undistributed earnings and cumulative translation adjustments from the date of acquisition since we have the ability to exert significant influence over operating and financial policies.

We have reclassified prior year's financial statements where appropriate to conform to 2005 presentations.

(2) In February 2005, we announced the acquisition of substantially all the exhaust assets of Gabilan Manufacturing, Inc., a privately held company that has developed and manufactured motorcycle exhaust systems for Harley-Davidson motorcycles since 1978. The company also produces aftermarket muffler kits for Harley-Davidson. We purchased Gabilan's assets for $11 million in cash and expect the acquisition to be accretive within the first year. Gabilan generated approximately $38 million in revenue in 2004. We began reporting Gabilan in our results of operations for the quarter end March 31, 2005.

(3) Effective January 1, 2005, we changed our accounting method for valuing inventory for our U.S. based operations from the last-in, first-out ("LIFO") method to the first-in, first-out ("FIFO") method. As a result, all U.S. inventories are now stated at the lower of cost, determined on a FIFO basis, or market. We elected to change to the FIFO method as we believe it is preferable for the following reasons: 1) the change will provide better matching of revenue and expenditures and 2) the change will achieve greater consistency in valuing our global inventory. Additionally, we initially adopted LIFO as it provided certain U.S. tax benefits which we no longer realize due to our U.S. net operating losses (when applied for tax purposes, tax laws require that LIFO be applied for GAAP as well). As a result of the change, we also expect to realize administrative efficiencies.

In accordance with GAAP, the change in inventory accounting has been applied by adjusting prior year's financial statements. The effect of the change in accounting principle as of December 31, 2004, was to increase inventories by $14 million, reduce deferred tax assets by $5 million, and increase retained earnings by $9 million. There was no impact on consolidated net income (loss) for the six-month periods ended June 30, 2004 from this restatement.

(4) In April 2004, we entered into three separate fixed-to-floating interest rate swaps with two separate financial institutions. These agreements swapped an aggregate of $150 million of fixed interest rate debt at an annual rate of 10 1/4 percent to floating interest rate debt at an annual rate of LIBOR plus an average spread of 5.68 percent. Each agreement requires semi-annual settlements through July 15, 2013. The LIBOR in effect for these swaps during the course of 2004 resulted in lower interest expense of approximately $3 million for the year ended December 31, 2004. Based on the rate in effect through July 15, 2005 and using the current LIBOR as determined under these agreements of 3.82 percent (which remains in effect until January 15, 2006), these swaps would reduce our 2005 annual interest expense by approximately $2 million compared to having this debt remain fixed. These swaps qualify as fair value hedges in accordance with Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging

10

TENNECO AUTOMOTIVE INC. AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(UNAUDITED)

Activities," as amended, and as such are recorded on the balance sheet at market value with an offset to the underlying hedged item, which is long-term debt. As of June 30, 2005, the fair value of the interest rate swaps was close to zero and as such did not have a material impact on our financial position.

In February 2005 we amended our senior credit facility to reduce by 75 basis points the interest rate on the term loan B facility and the tranche B-1 letter of credit/revolving loan facility. In connection with the amendment, we voluntarily prepaid $40 million in principal on the term loan B, reducing the term loan B facility from $396 million to $356 million.

Additional provisions of the amendment to the senior credit facility agreement were as follows: (i) amend the definition of EBITDA to exclude up to $60 million in restructuring-related expenses announced and taken after February 2005, (ii) increase permitted investments to $50 million, (iii) exclude expenses related to the issuance of stock options from the definition of consolidated net income, (iv) permit us to redeem up to $125 million of senior secured notes after January 1, 2008 (subject to certain conditions), (v) increase our ability to add commitments under the revolving credit facility by $25 million, and (vi) make other minor modifications. We incurred approximately $1 million in fees and expenses associated with this amendment, which were capitalized and are being amortized over the remaining term of the agreement.

Following the February 2005 voluntary prepayment of $40 million, the term loan B facility is payable as follows: $74 million due March 31, 2010, and $94 million due each of June 30, September 30 and December 12, 2010. The revolving credit facility requires that if any amounts are drawn, they be repaid by December 2008. Prior to that date, funds may be borrowed, repaid and reborrowed under the revolving credit facility without premium or penalty. Letters of credit may be issued under the revolving credit facility.

The tranche B-1 letter of credit/revolving loan facility requires that it be repaid by December 2010. We can borrow revolving loans from the tranche B-1 letter of credit/revolving loan facility and use that facility to support letters of credit. The tranche B-1 letter of credit/revolving loan facility lenders have deposited funds in an amount equal to the size of the facility with the administrative agent, who has invested that amount in time deposits. We do not have an interest in any of the funds on deposit. When we draw revolving loans under this facility, the loans are funded from the funds on deposit with the administrative agent. When we make repayments, the repayments are redeposited with the administrative agent.

The tranche B-1 letter of credit/revolving loan facility will be reflected as debt on our balance sheet only if we borrow money under this facility or if we use the facility to make payments for letters of credit. We will not be liable for any losses to or misappropriation of any (i) return due to the administrative agent's failure to achieve the return described above or to pay all or any portion of such return to any lender under such facility or (ii) funds on deposit in such account by such lender (other than the obligation to repay funds released from such accounts and provided to us as revolving loans under such facility).

In March 2005, we increased the amount of commitments under our revolving credit facility from $220 million to $285 million and reduced the amount of commitments under our tranche B-1 letter of credit/revolving loan facility from $180 million to $170 million. This reduction of our tranche B-1 letter of credit/revolving loan facility was required under the terms of the senior credit facility, as we had increased the amount of our revolving credit facility commitments by more than $55 million.

In April 2005, we further increased the amount of commitments under our revolving credit facility from $285 million to $300 million and, as required under the terms of our senior credit facility, reduced the amount of commitments under our tranche B-1 letter of credit/revolving loan facility from $170 million to $155 million.

(5) Over the past several years we have adopted plans to restructure portions of our operations. These plans were approved by the Board of Directors and were designed to reduce operational and administrative

11

TENNECO AUTOMOTIVE INC. AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(UNAUDITED)

overhead costs throughout the business. Prior to the change in accounting required for exit or disposal activities, we recorded charges to income related to these plans for costs that do not benefit future activities in the period in which the plans were finalized and approved, while actions necessary to affect these restructuring plans occurred over future periods in accordance with established plans.

In the fourth quarter of 2001, our Board of Directors approved a restructuring plan, a project known as Project Genesis, designed to lower our fixed costs, improve efficiency and utilization, and better optimize our global footprint. Project Genesis involved closing eight facilities, improving the process flow and efficiency through value mapping and plant arrangement at 20 facilities, relocating production among facilities, and centralizing some functional areas. The total of all these restructuring and other costs recorded in the fourth quarter of 2001 was $32 million before tax, $31 million after tax, or $0.81 per diluted common share. We eliminated 974 positions in connection with Project Genesis. Additionally, we executed this plan more efficiently than originally anticipated and as a result in the fourth quarter of 2002 reduced our reserves related to this restructuring activity by $6 million, which was recorded in cost of sales. In the fourth quarter of 2003, we reclassified $2 million of severance reserve to the asset impairment reserve. This reclassification became necessary, as actual asset impairments along with the sale of our closed facilities were different than the original estimates. We completed the remaining restructuring activities under Project Genesis as of the end of 2004. Since Project Genesis was announced, we have undertaken a number of related projects designed to restructure our operations, described below.

In the first quarter of 2003, we incurred severance costs of $1 million associated with eliminating 17 salaried positions through selective layoffs and an early retirement program. Additionally, 93 hourly positions were eliminated through selective layoffs in the quarter. These reductions were done to reduce ongoing labor costs in North America. This charge was primarily recorded in cost of sales.

In October of 2003, we announced the closing of an emission control manufacturing facility in Birmingham, U.K. Approximately 130 employees were eligible for severance benefits in accordance with union contracts and U.K. legal requirements. We incurred approximately $3 million in costs related to this action in 2004. This action is in addition to the plant closings announced in Project Genesis in the fourth quarter of 2001.

In October 2004, we announced a plan to eliminate 250 salaried positions through selected layoffs and an elective early retirement program. The majority of layoffs were at middle and senior management levels. We expect to incur total charges of approximately $24 to $26 million related to these reductions. As of June 30, 2005, we have incurred $23 million in severance costs. Of this total, $7 million was recorded in cost of sales and $16 million was recorded in selling, general and administrative expense. Of the total $23 million in severance costs incurred to date, $20 million were cash payments with the remainder accrued in other short-term liabilities.

Including the above costs, we incurred $5 million in restructuring and restructuring-related costs in the first half of 2005. Including the costs incurred in 2002 through 2004 of $59 million, we have incurred a total of $64 million for activities related to our restructuring initiatives.

Under the terms of our amended and restated senior credit agreement that took effect on December 12, 2003, we were allowed to exclude up to $60 million of cash charges and expenses, before taxes, related to cost reduction initiatives over the 2002 to 2006 time period from the calculation of the financial covenant ratios we are required to maintain under our senior credit agreement. In February of 2005, our senior credit facility was amended to exclude all remaining cash charges and expenses related to restructuring initiatives started before February of 2005. As of June 30, 2005, we have excluded $62 million in allowable charges relating to restructuring initiatives previously started.

(UNAUDITED)

Under our amended facility, we are allowed to exclude up to an additional $60 million of cash charges and expenses, before taxes, related to restructuring activities initiated after February 2005 from the calculation of the financial covenant ratios required under our senior credit facility. As of June 30, 2005, we have excluded $2 million in allowable charges relating to restructuring initiatives against the $60 million available under the terms of the February 2005 amendment to the senior credit facility.

(6) We are subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which we operate. We expense or capitalize, as appropriate, expenditures for ongoing compliance with environmental regulations that relate to current operations. We expense expenditures that relate to an existing condition caused by past operations and that do not contribute to current or future revenue generation. We record liabilities when environmental assessments indicate that remedial efforts are probable and the costs can be reasonably estimated. Estimates of the liability are based upon currently available facts, existing technology, and presently enacted laws and regulations taking into consideration the likely effects of inflation and other societal and economic factors. We consider all available evidence including prior experience in remediation of contaminated sites, other companies' cleanup experiences and data released by the United States Environmental Protection Agency or other organizations. These estimated liabilities are subject to revision in future periods based on actual costs or new information. Where future cash flows are fixed or reliably determinable, we have discounted the liabilities. All other environmental liabilities are recorded at their undiscounted amounts. We evaluate recoveries separately from the liability and, when they are assured, recoveries are recorded and reported separately from the associated liability in our financial statements.

As of June 30, 2005, we are designated as a potentially responsible party in one Superfund site. We have estimated our share of the remediation costs for this site to be less than $1 million in the aggregate. In addition to the Superfund site, we may have the obligation to remediate current or former facilities, and we estimate our share of remediation costs at these facilities to be approximately $10 million. For the Superfund site and the current and former facilities, we have established reserves that we believe are adequate for these costs. Although we believe our estimates of remediation costs are reasonable and are based on the latest available information, the cleanup costs are estimates and are subject to revision as more information becomes available about the extent of remediation required. At some sites, we expect that other parties will contribute to the remediation costs. In addition, at the Superfund site, the Comprehensive Environmental Response, Compensation and Liability Act provides that our liability could be joint and several, meaning that we could be required to pay in excess of our share of remediation costs. Our understanding of the financial strength of other potentially responsible parties at the Superfund site, and of other liable parties at our current and former facilities, has been considered, where appropriate, in our determination of our estimated liability.

We believe that any potential costs associated with our current status as a potentially responsible party in the Superfund site, or as a liable party at our current or former facilities, will not be material to our results of operations or consolidated financial position.

We also from time to time are involved in legal proceedings, claims or investigations that are incidental to the conduct of our business. Some of these proceedings allege damages against us relating to environmental liabilities (including toxic tort, property damage and remediation), intellectual property matters (including patent, trademark and copyright infringement, and licensing disputes), personal injury claims (including injuries due to product failure, design or warnings issues, and other product liability related matters), taxes, employment matters, and commercial or contractual disputes, sometimes related to acquisitions or divestitures. For example, one of our Chinese joint ventures is currently under investigation by local customs officials related to whether the joint venture applied the proper tariff code to certain of its imports. We vigorously defend ourselves against all of these claims. In future periods, we could be subjected to cash costs or non-cash charges to earnings if any of these matters is resolved on unfavorable terms. However, although the ultimate

13

TENNECO AUTOMOTIVE INC. AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(UNAUDITED)

outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claim, we do not expect that these legal proceedings or claims will have any material adverse impact on our future consolidated financial position or results of operations. In addition, we are subject to a number of lawsuits initiated by a significant number of claimants alleging health problems as a result of exposure to asbestos. Many of these cases involve significant numbers of individual claimants. However, only a small percentage of these claimants allege that they were automobile mechanics who were allegedly exposed to our former muffler products and a significant number appear to involve workers in other industries or otherwise do not include sufficient information to determine whether there is any basis for a claim against us. We believe, based on scientific and other evidence, it is unlikely that mechanics were exposed to asbestos by our former muffler products and that, in any event, they would not be at increased risk of asbestos-related disease based on their work with these products. Further, many of these cases involve numerous defendants, with the number of each in some cases exceeding 200 defendants from a variety of industries. Additionally, the plaintiffs either do not specify any, or specify the jurisdictional minimum, dollar amount for damages. As major asbestos manufacturers continue to go out of business, we may experience an increased number of these claims. We vigorously defend ourselves against these claims as part of our ordinary course of business. In future periods, we could be subject to cash costs or non-cash charges to earnings if any of these matters is resolved unfavorably to us. To date, with respect to claims that have proceeded sufficiently through the judicial process, we have regularly achieved favorable resolution in the form of a dismissal of the claim or a judgment in our favor. Accordingly, we presently believe that these asbestos-related claims will not have a material adverse impact on our future financial condition, results of operations or cash flows.

We provide warranties on some of our products. The warranty terms vary but range from one year up to limited lifetime warranties on some of our premium aftermarket products. Provisions for estimated expenses related to product warranty are made at the time products are sold or when specific warranty issues are identified on OE products. These estimates are established using historical information about the nature, frequency, and average cost of warranty claims. We actively study trends of warranty claims and take action to improve product quality and minimize warranty claims. We believe that the warranty reserve is appropriate; however, actual claims incurred could differ from the original estimates, requiring adjustments to the reserve. The reserve is included in both long-term and short-term liabilities on the balance sheet.

Below is a table that shows the activity in the warranty accrual accounts:

(7) In November 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No. 151, "Inventory Costs an amendment of Accounting Research Bulletin No. 43, Chapter 4." This statement requires idle facility expenses, excessive spoilage, double freight and rehandling costs to be recognized as current period charges regardless of whether they meet the criterion of "so abnormal." SFAS No. 151 is effective for fiscal years beginning after June 15, 2005. The adoption of SFAS No. 151 did not have a material impact on our financial position or results of operations.

In December 2004, the FASB revised SFAS No. 123, "Share-Based Payment" which supersedes Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees." This

14

TENNECO AUTOMOTIVE INC. AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(UNAUDITED)

revised statement establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity's equity instruments or that may be settled by the issuance of those equity instruments. The revised SFAS No. 123 is effective for interim reporting periods that begin at the beginning of the next fiscal year January 1, 2006. We estimate that the impact on our net income for the full year 2004 would not have exceeded approximately $2 million or $0.05 per diluted share had we adopted the revised SFAS No. 123.

In December 2004, the FASB issued FASB Staff Position, ("FSP") No. 109-1. FSP No. 109-1 provides guidance on the application of FASB Statement No. 109, "Accounting for Income Taxes," to the provision within The American Jobs Creation Act of 2004 ("The Act") that provides a tax deduction on qualified production activities. The purpose behind this special deduction is to provide a tax incentive to companies that maintain or expand U.S. manufacturing activities. FSP No. 109-1 was effective upon issuance. The adoption of FSP 109-1 did not have any impact on our consolidated financial statements.

In December 2004, the FASB issued FSP No. 109-2. FSP No. 109-2 addresses the question on the impact of a company's APB No. 23 Accounting for Income Taxes--Special Areas representation under The Act, which provides for a special one-time 85 percent dividend deduction on dividends from foreign subsidiaries. FSP No. 109-2 was effective upon issuance. The issuance of FSP No. 109-2 does not change how we apply APB No. 23, and therefore, did not have any impact on our consolidated financial statements.

In March 2005, the FASB issued Interpretation No. ("FIN") 46(R)-5, "Implicit Variable Interests under FASB Interpretation No. 46 (revised December 2003)." The statement addresses whether a reporting enterprise should consider whether it holds an implicit variable interest in a variable interest entity ("VIE") or potential VIE when specific conditions exist. The guidance should be applied in the first reporting period beginning after March 3, 2005. The adoption of FSP No. FIN 46(R)-5 does not have an impact on our consolidated financial statements.

In March 2005, the FASB issued FIN No. 47, "Accounting for Conditional Asset Retirement Obligations." This interpretation clarifies that the term conditional asset retirement obligation as used in FASB No. 143, "Accounting for Assets Retirement Obligation," refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. This interpretation is effective no later than the end of fiscal years ending after December 15, 2005. The adoption of FIN No. 47 is not expected to have a material impact on our financial position or results of operation.

In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Corrections," which supercedes APB No. 20, "Accounting Changes" and SFAS No. 3, "Reporting Accounting Changes in Interim Financial Statements." This statement changes the requirements for the accounting for and reporting of a change in accounting principle. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS No. 154 is not expected to have a material impact on our financial position or results of operation.

(8) We sell an interest in some of our U.S. trade accounts receivable to two third parties. Receivables become eligible for the program on a daily basis, at which time the receivables are sold to the third parties, net of a factoring discount, through a wholly-owned subsidiary. Under this agreement, as well as individual agreements with third parties in Europe, we have sold accounts receivable of $148 million at both June 30, 2005 and 2004, respectively. We recognized a loss of approximately $1 million for each of the six months ended June 30, 2005 and 2004, respectively, on these sales of trade accounts, representing the discount from book values at which these receivables were sold to the third parties. The discount rate varies based on funding cost incurred by the third parties, and it averaged four percent during the time period in 2005 when we sold

15

TENNECO AUTOMOTIVE INC. AND CONSOLIDATED SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(UNAUDITED)

receivables. We retained ownership of the remaining interest in the pool of receivables not sold to the third parties. The retained interest represents a credit enhancement for the program. We value the retained interest based upon the amount we expect to collect from our customers, which approximates book value.

(9) We account for our stock-based employee compensation plans under the recognition and measurement principles of APB Opinion No. 25, "Accounting for Stock Issued to Employees." As permitted by SFAS No. 123, "Accounting for Stock-Based Compensation," and amended by SFAS No. 148, "Accounting for Stock-based Compensation--Transition and Disclosure, an amendment of FASB Statement No. 123," we follow the disclosure only requirements of SFAS No. 123. The following table illustrates the effect on net income and earnings per share if we had applied the fair value recognition provisions of SFAS No. 123:

For the six months ended June 30, 2005, we made pension contributions of approximately $14 million for our domestic pension plans and $5 million for our foreign pension plans. Based on current actuarial estimates, we believe we will be required to make approximately $30 million to $35 million in contributions for the remainder of 2005.

We made postretirement benefit contributions of approximately $5 million during the first six months of 2005. Based on current actuarial estimates, we believe we will be required to make approximately $4 million in contributions for the remainder of 2005.

(12) We occasionally provide guarantees that could require us to make future payments in the event that the third party primary obligor does not make its required payments. We have not recorded a liability for any of these guarantees. The only third party guarantee we have made is the performance of lease obligations by a former affiliate. Our maximum liability under this guarantee was approximately $4 million at both June 30, 2005 and 2004, respectively. We have no recourse in the event of default by the former affiliate. However, we have not been required to make any payments under this guarantee.

Additionally, we have from time to time issued guarantees for the performance of obligations by some of our subsidiaries, and some of our subsidiaries have guaranteed our debt. All of our existing and future material domestic wholly-owned subsidiaries fully and unconditionally guarantee our senior credit facility, our senior secured notes and our senior subordinated notes on a joint and several basis. The arrangement for the senior credit facility is also secured by first-priority liens on substantially all our domestic assets and pledges of 66 percent of the stock of certain first-tier foreign subsidiaries. The arrangement for the $475 million senior secured notes is also secured by second-priority liens on substantially all our domestic assets, excluding some of the stock of our domestic subsidiaries. No assets or capital stock of our direct or indirect foreign subsidiaries secure these notes. You should also read Note 14 where we present the Supplemental Guarantor Condensed Consolidating Financial Statements.

We have issued guarantees through letters of credit in connection with some obligations of our affiliates. We have guaranteed through letters of credit support for local credit facilities, travel and procurement card programs, and cash management requirements for some of our subsidiaries totaling $26 million. We have also issued $19 million in letters of credit to support some of our subsidiaries' insurance arrangements. In addition, we have issued $3 million in guarantees through letters of credit to guarantee other obligations of subsidiaries primarily related to environmental remediation activities.

(13) In October 2004, we announced a change in the structure of our organization which changed our reportable segments. The European segment now includes South American operations. While this has no impact on our consolidated results, it changes our segment results.

We are a global manufacturer with three geographic reportable segments:
North America, Europe and South America, and Asia Pacific. Each segment manufactures and distributes ride control and emission control products primarily for the automotive industry. We have not aggregated individual operating segments within these reportable segments. We evaluate segment performance based primarily on income before interest expense, income taxes, and minority interest. Products are transferred between segments and geographic areas on a basis intended to reflect as nearly as possible the "market value" of the products.

The following table summarizes certain Tenneco segment information:

In July 2005, we announced a change in the structure of our organization that will change our reportable segments. The Europe and South America segment will now include our Indian operations. While this will have no impact on our consolidated results, it will change our segment results. This change would have increased the Europe and South America segment revenues by approximately $9 million for the second quarter and $16 million for the six months ended June 30, 2005. There would have been no impact on Europe and South America EBIT for both the second quarter and the six months ended June 30, 2005. The change in segment reporting will be reflected in our Form 10-Q for the quarter ended September 30, 2005.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
(UNAUDITED)

(14) Supplemental guarantor condensed financial statements are presented below:

Basis of Presentation

Subject to limited exceptions, all of our existing and future material domestic wholly owned subsidiaries (which are referred to as the Guarantor Subsidiaries) fully and unconditionally guarantee our senior subordinated notes due 2014 and our senior secured notes due 2013 on a joint and several basis. We have not presented separate financial statements and other disclosures concerning each of the Guarantor Subsidiaries because management has determined that such information is not material to the holders of the notes. Therefore, the Guarantor Subsidiaries are combined in the presentation below.

These condensed consolidating financial statements are presented on the equity method. Under this method, our investments are recorded at cost and adjusted for our ownership share of a subsidiary's cumulative results of operations, capital contributions and distributions, and other equity changes. You should read the condensed consolidating financial statements of the Guarantor Subsidiaries in connection with our consolidated financial statements and related notes of which this note is an integral part.

Distributions

There are no significant restrictions on the ability of the Guarantor Subsidiaries to make distributions to us.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EXECUTIVE SUMMARY

We are one of the world's leading manufacturers of automotive emission control and ride control products and systems. We serve both original equipment (OE) vehicle manufacturers and the repair and replacement markets, or aftermarket, globally through leading brands, including Monroe(R), Rancho(R), Clevite(R) Elastomers and Fric Rot(TM) ride control products and Walker(R), Fonos(TM), and Gillet(TM) emission control products. Worldwide we serve more than 30 different original equipment manufacturers, and our products or systems are included on six of the top 10 passenger car models produced in North American and Western Europe and all of the top 10 light truck models produced in North America for 2004. During 2004, our aftermarket customers were comprised of full-line and specialty warehouse distributors, retailers, jobbers, installer chains and car dealers. We operate more than 70 manufacturing facilities worldwide and employ approximately 18,400 people to service our customer's demands.

Factors that are critical to our success include new business awards, managing our overall global manufacturing footprint to ensure proper placement and workforce levels in line with business needs, maintaining competitive wages and benefits, maximizing efficiencies in manufacturing processes, fixing or eliminating unprofitable businesses and reducing overall costs. In addition, our ability to adapt to key industry trends, such as the consolidation of OE customers, increasing technologically sophisticated content, changing aftermarket distribution channels, increasing environmental standards and extended product life of automotive parts, also plays a critical role in our success. Other factors that are critical to our success include adjusting to environmental and economic challenges such as increases in the cost of raw materials and our ability to successfully reduce the impact of any such cost increases through material substitutions, cost reduction initiatives and other methods.

We have a substantial amount of indebtedness, with total debt, net of cash balances, of $1.346 billion as of June 30, 2005. As such, our ability to generate cash--both to fund operations and service our debt--is also a significant area of focus for our company. See "Liquidity and Capital Resources" below for further discussion of cash flows.

Total revenues for the second quarter of 2005 were $1.2 billion, a six percent increase over the second quarter of 2004. Higher global OE volumes, customer recovery related to higher steel costs, strengthening currencies, and improved aftermarket revenues primarily drove this increase. The balanced distribution of our customers, geographies, markets, products and platforms allowed us to outperform market production rates in a difficult auto environment. Gross margin for the second quarter of 2005 was 20.3 percent down 1.3 percent from 21.6 percent in the second quarter of 2004. Higher gross steel costs of $35 million, restructuring charges and business mix more than offset savings and improved efficiencies from Lean manufacturing, Six Sigma programs, cost recoveries, and other cost reduction initiatives. We reported selling, general, administrative and engineering expenses for the second quarter of 2005 of 9.4 percent of revenues, as compared to 10.7 percent of revenues for the second quarter of 2004. The improvement was driven by restructuring savings and tight discretionary spending controls. EBIT was $83 million for the second quarter of 2005, up $7 million from the $76 million reported in the second quarter of 2004. Stronger global volumes and lower restructuring-related expenses, customer changeover costs and consulting fees indexed to the stock price helped drive this improvement.

Total revenues for the first six months of 2005 were $2.3 billion, a six percent increase over the $2.1 billion reported for the same period last year. Strong OE volumes, customer recovery related to higher steel costs, improved aftermarket revenues and currency appreciation primarily drove this increase. Gross margin for first six months of 2005 was 19.8 percent down nine-tenths of a percent from 20.7 for the first six months of 2004 primarily due to the impact of higher materials costs. Selling, general, administrative and engineering expenses for the first six months of 2005 were 10.2 percent of revenues, compared to the 11.4 percent of revenues reported for the same period last year. The decrease was driven by higher sales volumes, headcount reductions taken at the end of 2004, and tight controls on discretionary spending. EBIT

29

was $127 million for the first six months of 2005, up $18 million from the $109 million reported for prior year. The increase in EBIT was primarily driven by higher volumes and lower restructuring-related expenses, customer changeover costs and consulting fees indexed to the stock price.

In October 2004, we announced a change in the structure of our organization that impacts our reportable segments. The European segment now includes South American operations. In addition, Asia Pacific is a new reportable segment that includes Asian and Australian operations. The change in segment reporting has been reflected in this management discussion and analysis for quarters ended June 30, 2005 and prior.

In February 2005, we announced the acquisition of substantially all the exhaust assets of Gabilan Manufacturing, Inc., a privately held company that has developed and manufactured motorcycle exhaust systems for Harley-Davidson motorcycles since 1978. The company also produces aftermarket muffler kits for Harley-Davidson. We purchased Gabilan's assets, including working capital adjustments, for $11 million in cash and expect the acquisition to be accretive within the first year. Gabilan generated approximately $38 million in revenue in 2004.

In July 2005, we announced a change in the structure of our organization that will change our reportable segments. The Europe and South America segment will now include our Indian operations. While this will have no impact on our consolidated results, it will change our segment results. This change would have increased the Europe and South America segment revenues by approximately $9 million for the second quarter and $16 million for the six months ended June 30, 2005. There would have been no impact on Europe and South America EBIT for both the second quarter and the six months ended June 30, 2005. The change in segment reporting will be reflected in our Form 10-Q for the quarter ended September 30, 2005.

RESULTS FROM OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 2005 AND 2004

NET SALES AND OPERATING REVENUES

The following tables reflect our revenues for the second quarter of 2005 and 2004. We present these reconciliations of revenues in order to reflect the trend in our sales in various product lines and geographic regions separately from the effects of doing business in currencies other than the U.S. dollar. Additionally, "pass-through" catalytic converter sales include precious metals pricing, which may be volatile. These "pass-through" catalytic converter sales occur when, at the direction of our OE customers, we purchase catalytic converters or components from suppliers, use them in our manufacturing process, and sell them as part of the completed system. While our original equipment customers assume the risk of this volatility, it impacts our reported revenue. Excluding "pass-through" catalytic converter sales removes this impact. We have not reflected any currency impact in the 2004 table since this is the base period for measuring the effects of currency during 2005 on our operations. We use this information to analyze the trend in our revenues before

30

these factors. We believe investors find this information useful in understanding period-to-period comparisons in our revenues.

Revenues from our North American operations increased $13 million in the second quarter of 2005 compared to the same period last year reflecting higher sales from both the OE and aftermarket businesses. Total North American OE revenues were up $11 million to $390 million in the second quarter of 2005, as compared to $379 million for the second quarter of 2004. OE emission control volumes for the second quarter of 2005 were flat with the prior year primarily as a result of lower pass-through sales. Pass-through catalytic converter sales were down 19 percent to $68 million, mostly driven by the expiration of the prior Ford Mustang platform. Adjusted for pass-through sales, OE emission control sales were up $13 million compared to the prior year. OE ride control revenues for the second quarter of 2005 increased nine percent from the prior year, driven by higher heavy-duty volumes as well as increased sales on specific Nissan and DaimlerChrysler platforms. Total OE revenues, excluding pass-through sales and currency, increased eight percent in the second quarter of 2005, while the North American light vehicle production experienced a two percent decline. Favorable platform mix, increasing exposure to Japanese OE manufacturers, strong heavy-duty ride control volumes and $10 million in revenues from our recent acquisition of the exhaust business for Harley Davidson helped offset production declines on key vehicle platforms. Aftermarket revenues for North America were $146 million in the second quarter of 2005, representing an increase of one percent compared to the prior year. Aftermarket ride control revenues increased $3 million or three percent in the second quarter of 2005, due to price increases, driven by higher steel costs. Aftermarket emission control revenues decreased four percent in the second quarter of 2005 compared to 2004. Customer consolidations and softer market conditions were primary reasons for the decline.

Our European and South American segment's revenues increased $60 million or 13 percent in the second quarter of 2005 compared to last year. Total Europe OE revenues were $382 million in the second quarter of

32

2005, up 12 percent from last year. OE emission control revenues increased 13 percent to $284 million in the second quarter of 2005, from $252 million in the prior year. Excluding a $4 million increase in pass-through sales and a $10 million increase due to strengthening currency, OE emission control revenues increased 12 percent over 2004. Our OE emission control revenues significantly exceeded the one percent European light vehicle production rate increase as a result of our position on successful platforms with Audi, Volkswagen, DaimlerChrysler, PSA, Porsche and BMW. OE ride control revenues increased to $98 million in the second quarter of 2005, up eight percent from $91 million a year ago. We changed our reporting in the second quarter of 2005 for an "assembly-only" contract with an European OE ride control customer and began accounting for those revenues as net of the related cost of sales. If we reported our second quarter 2004 revenues in the same manner, they would have been lower by $15 million. Our OE ride control revenue excluding a $5 million benefit from currency appreciation, increased one percent. We experienced an increase in OE ride control revenues due to stronger sales on new and existing platforms with Volkswagen, Audi, Ford, Nissan and Suzuki. European aftermarket sales were $109 million in the second quarter of 2005 compared to $103 million last year. Excluding $3 million attributable to currency appreciation, European aftermarket revenues increased three percent in the second quarter of 2005 compared to last year. Ride control aftermarket revenues, excluding the impact of currency, were down four percent compared to the prior year as a result of heightened competition, a soft market environment in Southern Europe and weaker exports due to the comparatively stronger euro. Aftermarket emission control revenues excluding currency increased by 10 percent, benefiting from market share gains that are offsetting market declines relating to the introduction of stainless steel (which lengthens our products' useful lives) by OE manufacturers about 10 years ago. South American revenues were $50 million during the second quarter of 2005, compared with $35 million a year earlier due to both higher OE and aftermarket revenues. Currency appreciation in Brazil and Argentina also added $7 million to South America's revenues.

Revenues from our Asia Pacific segment, which includes Australia and Asia, decreased $6 million to $103 million in the second quarter of 2005 as compared to $109 million in the prior year. The Chinese government's restraints on lending for new vehicles combined with continued soft consumer sales at our largest China customer, Volkswagen, drove decreased revenues of $14 million at our Asian operations. In Australia, stronger OE volumes and strengthening currency increased revenues by 16 percent to $59 million. Excluding the impact of currency, Australian revenues increased eight percent.

EBIT for North American operations increased to $52 million in the second quarter of 2005, from $50 million one year ago. Higher OE volumes increased EBIT by $5 million. Higher North American aftermarket revenues increased EBIT by $2 million. Lower selling, general, administrative and engineering costs improved EBIT by $8 million. These increases to North America EBIT were partially offset by steel cost increases, net of other material costs savings and recovery from customers. Included in North America's second quarter 2004 EBIT were $1 million in restructuring and restructuring-related expenses, $2 million of changeover costs for a major new aftermarket customer and $1 million in consulting fees indexed to stock price. The customer changeover costs include the cost of acquiring and disposing of competitor inventory when we supply aftermarket parts to a new customer. These costs were substantial in the second quarter of 2004 as we replaced one of our competitors at a significant customer. The 2004 consulting fees relate to a 1999 agreement that provided that a portion of the consultant's compensation would be in stock appreciation rights that were priced above the market price of our stock at the grant date. These rights expired in November 2004.

Our European and South American segment's EBIT was $27 million for the second quarter of 2005 compared to $17 million during the same period last year. Higher European OE volumes from both emission and ride control product lines contributed $6 million to EBIT. Higher European aftermarket revenues improved EBIT by $5 million. These increases to European EBIT were partially offset by steel cost increases, net of other material cost savings and recovery from customers. South American pricing offset higher steel and manufacturing costs. Included in Europe and South America's second quarter 2005 EBIT was $2 million in restructuring and restructuring-related expenses. Europe and South America's 2004 EBIT included $4 million in restructuring and restructuring-related expenses.

EBIT for our Asia Pacific segment was $4 million in the second quarter of 2005 compared to $9 million in the second quarter of 2004. Reduced volumes, primarily in China, negatively impacted EBIT by $4 million. Steel cost increases, net of other expected material cost savings and recovery from customers, also negatively impacted Asia Pacific's EBIT. Partially offsetting these decreases to EBIT were manufacturing cost reductions and efficiencies of $2 million.

recovery and lower selling, general, administrative and engineering costs were offset by higher steel costs. In Europe and South America, EBIT margins for the second quarter of 2005 increased one percent compared to the prior year. OE volume increases and customer price recovery more than offset the impact of higher steel costs. EBIT as a percentage of revenue for our Asia Pacific operations decreased four percent in the second quarter of 2005 from the prior year. Lower volumes and higher material costs drove the decrease.

INTEREST EXPENSE, NET OF INTEREST CAPITALIZED

We reported interest expense of $32 million in the second quarter of 2005 compared to $34 million in the prior year. This decrease is primarily due to the November 2004 refinancing of $500 million 11 5/8 percent senior subordinated notes for $500 million of 8 5/8 percent senior subordinated notes due in 2014. Interest expense was also reduced due to a $40 million prepayment of our senior term loan B facility and an amendment to our senior credit facility to reduce by 75 basis points the interest rate on the term loan B facility and the tranche B-1 letter of credit/revolving loan facility. These decreases were partially offset by higher interest expense on the variable portion of our debt. See more detailed explanations on our debt structure, including our issuance of $500 million of 8 5/8 percent senior subordinated notes due 2014 in November 2004, prepayments and amendments to our senior credit facility in February of 2005, and their anticipated impact on our interest expense, in "Liquidity and Capital Resources--Capitalization" later in this Management's Discussion and Analysis.

In April 2004, we entered into three separate fixed-to-floating interest rate swaps with two separate financial institutions. These agreements swapped an aggregate of $150 million of fixed interest rate debt at an annual rate of 10 1/4 percent to floating interest rate debt at an annual rate of LIBOR plus an average spread of 5.68 percent. Each agreement requires semi-annual settlements through July 15, 2013. The LIBOR in effect for these swaps during the course of 2004 resulted in lower interest expense of approximately $3 million for the year ended December 31, 2004. Based on the rate in effect through July 15, 2005 and using the current LIBOR as determined under these agreements of 3.82 percent (which remains in effect until January 15, 2006), these swaps would reduce our 2005 annual interest expense by approximately $2 million compared to having this debt remain fixed. These swaps qualify as fair value hedges in accordance with SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended, and as such are recorded on the balance sheet at market value with an offset to the underlying hedged item, which is long-term debt. As of June 30, 2005, the fair value of the interest rate swaps was close to zero and as such did not have a material impact on our financial position.

INCOME TAXES

Income taxes were $18 million in the second quarter of 2005, compared to $10 million in the prior year. The second quarter of 2005 included $1 million of tax expense, primarily related to adjusting state tax net operating loss carryforwards, partially offset by settlement of prior year tax issues on a more favorable basis than originally anticipated. Including these adjustments the effective tax for the second quarter of 2005 was 36 percent. Excluding this adjustment our effective tax rate was 33 percent. The second quarter of 2004 included $4 million of tax benefits, reflecting the settlement of prior year tax issues on a more favorable basis than originally anticipated. Including these benefits the effective tax for the first six months of 2004 was 23 percent. Excluding these benefits our effective tax rate was 34 percent.

EARNINGS PER SHARE

We reported net income of $33 million or $0.71 per diluted common share for the second quarter of 2005, as compared to earnings of $30 million or $0.69 per diluted common share for the second quarter of 2004. Included in the results for the second quarter of 2005 were negative impacts from expenses related to our restructuring activities and a tax adjustment for state net operating loss carryforwards. The net impact of these items decreased earnings per diluted share by $0.06. Included in the results for the second three months of 2004 were negative impacts from expenses related to our restructuring activities, customer changeover costs for a major new aftermarket customer, consulting fees indexed to the stock price and tax benefits for the resolution of outstanding tax issues. The net impact of these items decreased earnings per diluted share by

$0.01. Please read the Notes to the consolidated financial statements for more detailed information on earnings per share.

RESTRUCTURING AND OTHER NONRECURRING CHARGES

Over the past several years we have adopted plans to restructure portions of our operations. These plans were approved by the Board of Directors and were designed to reduce operational and administrative overhead costs throughout the business. Prior to the change in accounting required for exit or disposal activities, we recorded charges to income related to these plans for costs that do not benefit future activities in the period in which the plans were finalized and approved, while actions necessary to affect these restructuring plans occurred over future periods in accordance with established plans.

In the fourth quarter of 2001, our Board of Directors approved a restructuring plan, a project known as Project Genesis, designed to lower our fixed costs, improve efficiency and utilization, and better optimize our global footprint. Project Genesis involved closing eight facilities, improving the process flow and efficiency through value mapping and plant arrangement at 20 facilities, relocating production among facilities, and centralizing some functional areas. The total of all these restructuring and other costs recorded in the fourth quarter of 2001 was $32 million before tax, $31 million after tax, or $0.81 per diluted common share. We eliminated 974 positions in connection with Project Genesis. Additionally, we executed this plan more efficiently than originally anticipated and as a result in the fourth quarter of 2002 reduced our reserves related to this restructuring activity by $6 million, which was recorded in cost of sales. In the fourth quarter of 2003, we reclassified $2 million of severance reserve to the asset impairment reserve. This reclassification became necessary, as actual asset impairments along with the sale of our closed facilities were different than the original estimates. We completed the remaining restructuring activities under Project Genesis as of the end of 2004. Since Project Genesis was announced, we have undertaken a number of related projects designed to restructure our operations, described below.

In the first quarter of 2003, we incurred severance costs of $1 million associated with eliminating 17 salaried positions through selective layoffs and an early retirement program. Additionally, 93 hourly positions were eliminated through selective layoffs in the quarter. These reductions were done to reduce ongoing labor costs in North America. This charge was primarily recorded in cost of sales.

In October of 2003, we announced the closing of an emission control manufacturing facility in Birmingham, U.K. Approximately 130 employees were eligible for severance benefits in accordance with union contracts and U.K. legal requirements. We incurred approximately $3 million in costs related to this action in 2004. This action is in addition to the plant closings announced in Project Genesis in the fourth quarter of 2001.

In October 2004, we announced a plan to eliminate 250 salaried positions through selected layoffs and an elective early retirement program. The majority of layoffs were at middle and senior management levels. We expect to incur total charges of approximately $24 to $26 million related to these reductions. As of June 30, 2005, we have incurred $23 million in severance costs. Of this total, $7 million was recorded in cost of sales and $16 million was recorded in selling, general and administrative expense. Of the total $23 million in severance costs incurred to date, $20 million were cash payments with the remainder accrued in other short-term liabilities. We expect to generate savings of approximately $20 million annually from this initiative.

Including the above costs, we incurred $5 million in restructuring and restructuring-related costs in the first half of 2005. Including the costs incurred in 2002 through 2004 of $59 million, we have incurred a total of $64 million for activities related to our restructuring initiatives.

We have generated about $31 million of annual savings from Project Genesis. Approximately $7 million of savings was related to closing the eight facilities, approximately $16 million of savings was related to value mapping and plant arrangement and approximately $8 million of savings was related to relocating production among facilities and centralizing some functional areas. There have been no significant deviations from planned savings. All actions for Project Genesis have been completed.

Under the terms of our amended and restated senior credit agreement that took effect on December 12, 2003, we were allowed to exclude up to $60 million of cash charges and expenses, before taxes, related to cost reduction initiatives over the 2002 to 2006 time period from the calculation of the financial covenant ratios we are required to maintain under our senior credit agreement. In February of 2005, our senior credit facility was amended to exclude all remaining cash charges and expenses related to restructuring initiatives started before February of 2005. As of June 30, 2005, we have excluded $62 million in allowable charges relating to restructuring initiatives previously started.

Under our amended facility, we are allowed to exclude up to an additional $60 million of cash charges and expenses, before taxes, related to restructuring activities initiated after February 2005 from the calculation of the financial covenant ratios required under our senior credit facility. As of June 30, 2005, we have excluded $2 million in allowable charges relating to restructuring initiatives against the $60 million available under the terms of the February 2005 amendment to the senior credit facility.

In addition to the announced actions, we will continue to evaluate additional opportunities and expect that we will initiate actions that will reduce our costs through implementing the most appropriate and efficient logistics, distribution and manufacturing footprint for the future. There can be no assurances, however, that we will undertake additional restructuring actions. Actions that we take, if any, will require the approval of our Board of Directors, or its authorized committee. We plan to conduct any workforce reductions that result in compliance with all legal and contractual requirements including obligations to consult with workers' councils, union representatives and others.

CRITICAL ACCOUNTING POLICES

We prepare our financial statements in accordance with accounting principles generally accepted in the United States of America. Preparing our financial statements in accordance with generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The following paragraphs include a discussion of some critical areas where estimates are required.

Revenue Recognition

We recognize revenue for sales to our original equipment and aftermarket customers under the terms of our arrangements with those customers, generally at the time of shipment from our plants or distribution centers. For our aftermarket customers, we provide for promotional incentives and returns at the time of sale. Estimates are based upon the terms of the incentives and historical experience with returns. Where we have offered product warranty, we also provide for warranty costs. Those estimates are based upon historical experience and upon specific warranty issues as they arise. While we have not experienced any material differences between these estimates and our actual costs, it is reasonably possible that future warranty issues could arise that could have a significant impact on our financial statements.

Long-Term Receivables

We expense pre-production design and development costs incurred for our original equipment customers unless we have a contractual guarantee for reimbursement of those costs from the customer. At June 30, 2005, we had $16 million recorded as a long-term receivable from original equipment customers for guaranteed pre-production design and development arrangements. While we believe that the vehicle programs behind these arrangements will enter production, these arrangements allow us to recover our pre-production design and development costs in the event that the programs are cancelled or do not reach expected production levels. We have not experienced any material losses on arrangements where we have a contractual guarantee of reimbursement from our customers.

37

Income Taxes

We have a U.S. Federal tax net operating loss ("NOL") carryforward at June 30, 2005, of $561 million, which will expire in varying amounts from 2018 to 2025. The federal tax effect of that NOL is $196 million, and is recorded as an asset on our balance sheet at June 30, 2005. We estimate, based on available evidence both positive and negative, that it is more likely than not that we will utilize the NOL within the prescribed carryforward period. That estimate is based upon our expectations regarding future taxable income of our U.S. operations and upon strategies available to accelerate usage of the NOL. Circumstances that could change that estimate include future U.S. earnings at lower than expected levels or a majority ownership change as defined in the rules of the U.S. tax law. If that estimate changed, we would be required to cease recognizing an income tax benefit for any new NOL and could be required to record a reserve for some or all of the asset currently recorded on our balance sheet. As of June 30, 2005, we believe that there has been a significant change in our ownership, but not a majority change, in the last three years.

Stock-Based Compensation

We utilize the intrinsic value method to account for our stock-based compensation plans in accordance with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees." If our compensation costs for our stock-based compensation plans were determined using the fair value method of accounting as provided in Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation," we estimate that our pro-forma net income (loss) and earnings (loss) per share would be lower by less than $1 million or $0.01 per diluted share for the second quarter of 2005 compared to less than $1 million or $0.02 per diluted share for the second quarter of 2004.

Goodwill and Other Intangible Assets

We utilize an impairment-only approach to value our purchased goodwill in accordance with SFAS No. 142, "Goodwill and Other Intangible Assets." Each year in the fourth quarter, we perform an impairment analysis on the balance of goodwill. Inherent in this calculation is the use of estimates as the fair value of our designated reporting units is based upon the present value of our expected future cash flows. In addition, our calculation includes our best estimate of our weighted average cost of capital and growth rate. If the calculation results in a fair value of goodwill which is less than the book value of goodwill, an impairment charge would be recorded in the operating results of the impaired reporting unit.

Pension and Other Postretirement Benefits

We have various defined benefit pension plans that cover substantially all of our employees. We also have postretirement health care and life insurance plans that cover a majority of our domestic employees. Our pension and postretirement health care and life insurance expenses and valuations are dependent on management's assumptions used by our actuaries in calculating such amounts. These assumptions include discount rates, health care cost trend rates, long-term return on plan assets, retirement rates, mortality rates and other factors. Health care cost trend rate assumptions are developed based on historical cost data and an assessment of likely long-term trends. Retirement rates are based primarily on actual plan experience while mortality rates are based upon the general population experience which is not expected to differ materially from our experience.

Our approach to establishing the discount rate assumption for both our domestic and foreign plans starts with high-quality investment-grade bonds adjusted for an incremental yield based on actual historical performance. This incremental yield adjustment is the result of selecting securities whose yields are higher than the "normal" bonds that comprise the index. Based on this approach, at September 30, 2004 we lowered the weighted average discount rate for pension plans to 6.0 percent, from 6.1 percent. The discount rate for postretirement benefits was lowered from 6.5 percent at September 30, 2003 to 6.25 percent at September 30, 2004.

Our approach to determining expected return on plan asset assumptions evaluates both historical returns as well as estimates of future returns, and is adjusted for any expected changes in the long-term outlook for the

38

equity and fixed income markets. As a result, our estimate of the weighted average long-term rate of return on plan assets for our pension plans was 8.4 percent for both 2004 and 2005.

Except in the U.K., generally, our pension plans do not require employee contributions. Our policy is to fund our pension plans in accordance with applicable U.S. and foreign government regulations and to make additional payments as funds are available to achieve full funding of the accumulated benefit obligation. At June 30, 2005, all legal funding requirements had been met. Other postretirement benefit obligations, such as retiree medical, and certain foreign pension plans are not funded.

Inventory Valuation

Effective January 1, 2005, we changed our accounting method for valuing inventory for our U.S. based operations from the last-in, first-out ("LIFO") method to the first-in, first-out ("FIFO") method. As a result, all U.S. inventories are now stated at the lower of cost, determined on a FIFO basis, or market. We elected to change to the FIFO method as we believe it is preferable for the following reasons: 1) the change will provide better matching of revenue and expenditures and 2) the change will achieve greater consistency in valuing our global inventory. Additionally, we initially adopted LIFO as it provided certain U.S. tax benefits which we no longer realize due to our U.S. net operating losses (when applied for tax purposes, tax laws require that LIFO be applied for accounting principles generally accepted in the United States of America ("GAAP") as well). As a result of the change, we also expect to realize administrative efficiencies.

In accordance with GAAP, the change in inventory accounting has been applied by adjusting prior year's financial statements. The effect of the change in accounting principle as of December 31, 2004, was to increase inventories by $14 million, reduce deferred tax assets by $5 million, and increase retained earnings by $9 million. There was no impact on consolidated net income (loss) for the six-month periods ended June 30, 2004 from this restatement.

CHANGES IN ACCOUNTING PRONOUNCEMENTS

In November 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No. 151, "Inventory Costs an amendment of Accounting Research Bulletin No. 43, Chapter 4." This statement requires idle facility expenses, excessive spoilage, double freight and rehandling costs to be recognized as current period charges regardless of whether they meet the criterion of "so abnormal." SFAS No. 151 is effective for fiscal years beginning after June 15, 2005. The adoption of SFAS No. 151 did not have a material impact on our financial position or results of operations.

In December 2004, the FASB revised SFAS No. 123, "Share-Based Payment" which supersedes Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees." This revised statement establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity's equity instruments or that may be settled by the issuance of those equity instruments. The revised SFAS No. 123 is effective for interim reporting periods that begin at the beginning of the next fiscal year January 1, 2006. We estimate that the impact on our net income for the full year 2004 would not have exceeded approximately $2 million or $0.05 per diluted share had we adopted the revised SFAS No. 123.

In December 2004, the FASB issued FASB Staff Position, ("FSP") No. 109-1. FSP No. 109-1 provides guidance on the application of FASB Statement No. 109, "Accounting for Income Taxes," to the provision within The American Jobs Creation Act of 2004 ("The Act") that provides a tax deduction on qualified production activities. The purpose behind this special deduction is to provide a tax incentive to companies that maintain or expand U.S. manufacturing activities. FSP No. 109-1 was effective upon issuance. The adoption of FSP 109-1 did not have any impact on our consolidated financial statements.

In December 2004, the FASB issued FSP No. 109-2. FSP No. 109-2 addresses the question on the impact of a company's APB No. 23 Accounting for Income Taxes--Special Areas representation under The Act, which provides for a special one-time 85 percent dividend deduction on dividends from foreign

39

subsidiaries. FSP No. 109-2 was effective upon issuance. The issuance of FSP No. 109-2 does not change how we apply APB No. 23, and therefore, did not have any impact on our consolidated financial statements.

In March 2005, the FASB issued Interpretation No. ("FIN") 46(R)-5, "Implicit Variable Interests under FASB Interpretation No. 46 (revised December 2003)." The statement addresses whether a reporting enterprise should consider whether it holds an implicit variable interest in a variable interest entity ("VIE") or potential VIE when specific conditions exist. The guidance should be applied in the first reporting period beginning after March 3, 2005. The adoption of FSP No. FIN 46(R)-5 does not have an impact on our consolidated financial statements.

In March 2005, the FASB issued FIN No. 47, "Accounting for Conditional Asset Retirement Obligations." This interpretation clarifies that the term conditional asset retirement obligation as used in FASB No. 143, "Accounting for Assets Retirement Obligation," refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. This interpretation is effective no later than the end of fiscal years ending after December 15, 2005. The adoption of FIN No. 47 is not expected to have a material impact on our financial position or results of operation.

In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Corrections," which supercedes APB No. 20, "Accounting Changes" and SFAS No. 3, "Reporting Accounting Changes in Interim Financial Statements." This statement changes the requirements for the accounting for and reporting of a change in accounting principle. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS No. 154 is not expected to have a material impact on our financial position or results of operation.

Revenues from our North American operations increased $15 million in the first six months of 2005 compared to last year's first six months reflecting higher sales from both OE and aftermarket businesses. Total North American OE revenues increased one percent to $765 million in the first six months of this year. OE emission control revenues were down three percent in the first six months of 2005 as compared to the prior year. Pass-through emission control sales decreased 22 percent to $135 million in the first six months of 2005. Adjusted for pass-through sales, and currency, OE emission control sales were up five percent compared to the prior year. OE ride control revenues increased eight percent from the prior year. Total OE revenues, excluding pass-through sales, and currency, increased six percent in the first six months of 2005, while North American light vehicle production was down three percent from the first six months a year ago. Our revenue improvement was greater than the North American light vehicle production rate primarily due to our strong position on top-selling platforms, as well as higher heavy-duty volumes. Aftermarket revenues for North America were $276 million in the first six months of 2005, representing an increase of four percent compared to the same period in the prior year. Aftermarket ride control revenues increased $9 million or 5 percent in the first six months of 2005, primarily due to customer recovery and higher sales of premium priced products. Aftermarket emission control revenues increased one percent in the first six months of 2005 compared to 2004, mostly due to price increases driven by higher steel costs.

Our European and South American segment's revenues increased $125 million or 14 percent in the first six months of 2005 compared to last year's first six months. Total Europe OE revenues were $763 million, up 14 percent from the first six months of last year. OE emission control revenues in the first six months increased 12 percent to $556 million from $495 million in the prior year. Excluding a $2 million increase in pass-through sales and a $26 million increase due to strengthening currency, OE emissions control revenues

42

increased 10 percent over the first six months of 2004. This improvement was greater than overall European production levels, which remained relatively unchanged during the first six months compared to a year ago. Strong volumes on PSA, DaimlerChrysler, Volkswagen, Audi, BMW and Porsche platforms more than offset the general market's flat production rates. OE ride control revenues in the first six months increased to $207 million, up 18 percent from $176 million a year ago. We changed our reporting in the second quarter of 2005 for an "assembly-only" contract with an European OE ride control customer and began accounting for those revenues as net of the related cost of sales. Excluding a $16 million benefit from currency appreciation, OE ride control revenues increased eight percent. We experienced this revenue increase despite the overall flat market build rates due to stronger sales on new and existing platforms with Volkswagen, Audi, Ford, Nissan, and Suzuki. European aftermarket sales were $191 million in the first six months of this year compared to $183 million in last year's first six months. Excluding $7 million attributable to currency appreciation, European aftermarket revenues were relatively flat in the first six months of 2005 compared to the same period last year. Ride control aftermarket revenues, excluding the impact of currency, were down five percent compared with the prior year, reflecting continued market pressure from customer consolidations. Aftermarket emission control revenues were up 10 percent to $103 million compared to the six month period of last year. Excluding the impact of currency, European aftermarket emission control revenues increased five percent from the prior year. Stronger volumes, pricing and currency appreciation increased South American revenues by $25 million or 38 percent over the same period last year.

Revenues from our Asia Pacific operations, which include Australia and Asia, decreased $5 million to $192 million in the first six months of 2005 as compared to $197 million in the first six months of the prior year. Lower OE volumes and pass-through sales drove decreased revenues of $11 million at our Asian operations. In Australia, stronger OE volumes and strengthening currency increased revenues by six percent to $106 million.

EBIT for North American operations increased to $89 million in the first six months of 2005, from $80 million one year ago. Higher OE volumes increased EBIT by $6 million. Higher North American aftermarket revenues increased EBIT by $11 million. Lower selling, general, administrative and engineering costs improved EBIT by $18 million. These increases to North America EBIT were partially offset by steel cost increases, net of other material costs savings and recovery from customers. Included in North America's EBIT for the first six months of 2005 was $2 million in restructuring and restructuring-related costs. Included in North America's EBIT for the first six months of 2004 were $3 million in restructuring and restructuring-related expenses, $8 million of changeover costs for a major new aftermarket customer and $2 million in consulting fees indexed to stock price. The customer changeover costs include the cost of acquiring and disposing of competitor inventory when we supply aftermarket parts to a new customer. These costs were substantial in the first half of 2004 as we replaced a competitor at a significant customer. The 2004 consulting fees relate to a 1999 agreement that provided that a portion of the consultant's compensation would be in stock appreciation rights that were priced above the market price of our stock at the grant date. These rights expired in November 2004.

Our European and South American segment's EBIT was $32 million for the first half of 2005 compared to $17 million during the same period last year. Higher European OE volumes from both emission and ride control product lines contributed $10 million to EBIT. Higher Europe aftermarket revenues improved EBIT by $7 million. These increases to European EBIT were partially offset by steel cost increases, net of other material cost savings and recovery from customers. In addition, higher selling, general, administrative, and engineering costs reduced EBIT by $3 million. South American pricing offset higher steel and manufacturing costs. Included in Europe and South America's EBIT for the first six months of 2005 was $3 million in restructuring and restructuring-related expenses. Europe and South America's 2004 EBIT included $7 million in restructuring and restructuring-related expenses and $1 million in consulting fees indexed to the stock price.

EBIT for our Asia Pacific segment was $6 million in the first six months of 2005 compared to $12 million in the first six months of 2004. Reduced volumes, primarily in China, negatively impacted EBIT by $5 million. Higher selling, general, administrative, and engineering costs reduced EBIT by $3 million. Steel cost increases, net of other material cost savings and recovery from customers, also negatively impacted Asia Pacific's EBIT. Partially offsetting these decreases to EBIT were manufacturing cost reductions and efficiencies of $7 million. Asia Pacific's 2004 EBIT included $1 million in consulting fees indexed to the stock price.

In North America, EBIT as a percentage of revenue for the first six months of 2005 was up one percent compared to the prior year. Higher volumes in OE segments, customer price recovery, and lower selling, general, and administrative costs, were partially offset by higher steel costs. In Europe and South America, EBIT margins for the first six months of 2005 were up one percent compared with the same period last year. OE volume increases, customer price recovery and cost savings more than offset the impact of higher steel and selling, general, administrative, and engineering costs. EBIT as a percentage of revenue for our Asia Pacific operations decreased to three percent in the first six months of 2005 compared to six percent in the prior year. Lower volumes and higher material costs primarily drove the decrease.

INTEREST EXPENSE, NET OF INTEREST CAPITALIZED

We reported interest expense of $64 million for the first six months of 2005 compared to $69 million in the prior year. This decrease is primarily due to the November 2004 refinancing of $500 million 11 5/8 percent senior subordinated notes for $500 million of 8 5/8 percent senior subordinated notes due in 2014. Interest expense was also reduced due to a $40 million prepayment of our senior term loan B facility and an amendment to our senior credit facility to reduce by 75 basis points the interest rate on the term loan B facility and the tranche B-1 letter of credit/revolving loan facility. These decreases were partially offset by higher interest expense on the variable portion of our debt. See more detailed explanations on our debt structure, including our issuance of $500 million of 8 5/8 percent senior subordinated notes due 2014 in November 2004, prepayments and amendments to our senior credit facility in February of 2005, and their anticipated impact on our interest expense, in "Liquidity and Capital Resources--Capitalization" later in this Management's Discussion and Analysis.

INCOME TAXES

Income tax expense was $22 million for the first six months of 2005, compared to $9 million for the first six months of 2004. The first six months of 2005 included $1 million of tax expense, primarily related to adjusting state tax net operating loss carryforwards, partially offset by settlement of prior year tax issues on a more favorable basis than originally anticipated. Including these adjustments the effective tax for the first six months of 2005 was 36 percent. Excluding these adjustments our effective tax rate was 34 percent. The first six months of 2004 included $5 million of tax benefits, reflecting the settlement of prior year tax issues on a more favorable basis than originally anticipated. Including these benefits the effective tax for the first six months of 2004 was 23 percent. Excluding these benefits our effective tax rate was 34 percent.

EARNINGS PER SHARE

We reported earnings per diluted common share of $0.88 for the first six months of 2005, compared to $0.65 per diluted share for the first six months of 2004. Included in the results for the first six months of 2005 were the negative impacts from expenses related to our restructuring activities and a tax adjustment for state net operating loss carryforwards. In total, these items decreased earnings per diluted common share by $0.09. Included in the results for the first six months of 2004 were the negative impacts from expenses related to our restructuring activities, customer changeover costs for a major new aftermarket customer, consulting fees indexed to the stock price and benefits for the resolution of outstanding tax issues. In total, these items decreased earnings per diluted common share by $0.20. You should also read the Notes to the financial statements for more detailed information on earnings per share.

General. The year-to-date decrease in shareholders' equity primarily results from $75 million related to the translation of foreign balances into U.S. dollars. This amount was partially offset by our net income, premium on common stock issued pursuant to benefit plans and other transactions which contributed $45 million to shareholders' equity. Although our book equity balance was small at June 30, 2005, it should

45

not affect our business operations. We have no debt covenants that are based upon our book equity, and there are no other agreements that are adversely impacted by our relatively low book equity. You should also read Note 4 to our consolidated financial statements.

Short-term debt, which includes the current portion of long-term obligations and borrowings by foreign subsidiaries, as well as our revolving credit facilities, increased approximately $30 million primarily related to borrowings outstanding under our credit facilities. The current portion of long-term debt decreased by approximately $4 million and was offset by a $1 million increase in foreign subsidiaries' obligations. Borrowings under our revolving credit facilities were approximately $33 million as of June 30, 2005. There were no borrowings outstanding under our revolving credit facilities as of June 30, 2004. The overall decrease in long-term debt resulted from payments made on our outstanding long-term debt and capital leases in addition to our position on interest rate swaps entered into in April 2004. See below for further information on the interest rate swaps.

Senior Credit Facility--Overview and Recent Transactions. Our financing arrangements are primarily provided by a committed senior secured financing arrangement with a syndicate of banks and other financial institutions. The arrangement is secured by substantially all our domestic assets and pledges of 66 percent of the stock of certain first-tier foreign subsidiaries, as well as guarantees by our material domestic subsidiaries. We originally entered into this facility in 1999 and since that time have periodically requested and received amendments to the facility for various purposes. In December of 2003, we engaged in a series of transactions that resulted in the full refinancing of the facility, through an amendment and restatement. In February 2005, we amended the facility, which resulted in reduced interest rates on the term loan B and tranche B-1 letter of credit/revolving loan portions of the facility. We also made a voluntary prepayment of $40 million on the term loan B facility, reducing borrowings to $356 million. During the first six months of 2005, we increased the amount of commitments under our revolving credit facility from $220 million to $300 million and reduced the amount of commitments under our tranche B-1 letter of credit/revolving loan facility from $180 million to $155 million. As of June 30, 2005, the senior credit facility consisted of a seven-year, $356 million term loan B facility maturing in December 2010; a five-year, $300 million revolving credit facility maturing in December 2008; and a seven-year, $155 million tranche B-1 letter of credit/revolving loan facility maturing in December 2010. These transactions are described in more detail below.

In June 2003, we issued $350 million of 10 1/4 percent senior secured notes. The notes have a final maturity date of July 15, 2013. In December 2003, we amended and restated our senior credit facility and issued an additional $125 million of 10 1/4 percent senior secured notes. We incurred $27 million in fees associated with the issuance of the aggregate $475 million of 10 1/4 percent senior secured notes and the amendment and restatement of our senior credit facility. These fees will be amortized over the term of the senior secured notes and the amended and restated senior credit facility. Based on our use of the net proceeds from both the June and December 2003 transactions, these transactions would have increased our annual interest expense by approximately $9 million. This does not give effect to the fixed-to-floating interest rate swaps we completed in April 2004, described below.

In April 2004, we entered into three separate fixed-to-floating interest rate swaps with two separate financial institutions. These agreements swapped an aggregate of $150 million of fixed interest rate debt at an annual rate of 10 1/4 percent to floating interest rate debt at an annual rate of LIBOR plus an average spread of 5.68 percent. Each agreement requires semi-annual settlements through July 15, 2013. The LIBOR in effect for these swaps during the course of 2004 resulted in lower interest expense of approximately $3 million for the year ended December 31, 2004. Based upon the rate in effect through July 15, 2005 and using the current LIBOR as determined under these agreements of 3.82 percent (which remains in effect until January 15, 2006), these swaps would reduce our 2005 annual interest expense by approximately $2 million, compared to having this debt remain fixed. These swaps qualify as fair value hedges in accordance with SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended, and as such are recorded on the balance sheet at market value with an offset to the underlying hedged item, which is long-term debt. As of June 30, 2005, the fair value of the interest rate swaps was close to zero and as such did not have a material impact on our financial position. On June 30, 2005, we had $994 million in long-term debt obligations that have fixed interest rates. Of that amount, $489 million is fixed through July 2013 and $500 million through

46

November 2014, while the remainder is fixed over periods of 2005 through 2025. Included in the $489 million is $150 million of long-term debt obligations subject to variable interest rates as a result of our swap agreements. There is also $369 million in long-term debt obligations that have variable interest rates based on a current market rate of interest.

In November 2004, we refinanced our $500 million of 11 5/8 percent senior subordinated notes maturing in October of 2009 with new senior subordinated notes. The new notes have an interest rate of 8 5/8 percent, a maturity date of November 15, 2014 and contain substantially similar terms as the notes refinanced. Premium payments and other fees in connection with the refinancing of these notes totaled approximately $40 million, including a $29 million or 5.813% price premium over par on the redeemed notes. The new notes accrue interest from November 19, 2004 with an initial interest payment date of May 15, 2005. These notes are described in more detail below under "Senior Secured and Subordinated Notes."

In connection with the refinancing of the $500 million in senior subordinated notes we amended the senior credit facility effective November 17, 2004. This amendment allowed us to use up to $50 million in cash on hand to pay redemption premiums and/or other fees and costs in connection with the redemption and refinancing of the senior subordinated notes. This amendment also excluded any redemption premium associated with the 11 5/8 percent senior subordinated notes and any interest incurred on the notes between the call date of November 19, 2004 and the redemption date of December 20, 2004 from cash interest expense for purposes of the definition of consolidated interest expense in the senior credit facility. In exchange for these amendments, we agreed to pay a small fee to the consenting lenders. We also incurred approximately $13 million in legal, advisory and other costs related to the amendment and the issuance of the new senior subordinated notes. These amounts were capitalized and will be amortized over the remaining terms of the senior subordinated notes and senior credit facility.

Our interest expense increased in 2004 by $42 million due to the fees and expenses associated with the refinancing of our senior subordinated notes, which includes an expense of $8 million for existing deferred debt issuance costs associated with the 11 5/8 percent senior subordinated notes. Beginning in 2005, annual interest expense savings from this transaction are anticipated to be about $15 million. This does not give effect to the fixed-to-floating interest rate swaps we completed in April 2004 described above.

In February 2005 we amended our senior credit facility to reduce by 75 basis points the interest rate on the term loan B facility and the tranche B-1 letter of credit/revolving loan facility. In connection with the amendment, we voluntarily prepaid $40 million in principal on the term loan B, reducing the term loan B facility from $396 million to $356 million.

Additional provisions of the amendment to the senior credit facility agreement were as follows: (i) amend the definition of EBITDA to exclude up to $60 million in restructuring-related expenses announced and taken after February 2005, (ii) increase permitted investments to $50 million, (iii) exclude expenses related to the issuance of stock options from the definition of consolidated net income, (iv) permit us to redeem up to $125 million of senior secured notes after January 1, 2008 (subject to certain conditions), (v) increase our ability to add commitments under the revolving credit facility by $25 million, and (vi) make other minor modifications. We incurred approximately $1 million in fees and expenses associated with this amendment, which were capitalized and are being amortized over the remaining term of the agreement. As a result of the amendment and the voluntary prepayment of $40 million under the term loan B, our interest expense in 2005 will be approximately $6 million lower than what it would otherwise have been.

During the first six months of 2005, we increased the amount of commitments under our revolving credit facility from $220 million to $300 million and reduced the amount of commitments under our tranche B-1 letter of credit/revolving loan facility from $180 million to $155 million. This reduction of our tranche B-1 letter of credit/revolving loan facility was required under the terms of the senior credit facility, as we had increased the amount of our revolving credit facility commitments by more than $55 million.

Senior Credit Facility--Forms of Credit Provided. Following the February 2005 voluntary prepayment of $40 million, the term loan B facility is payable as follows: $74 million due March 31, 2010, and $94 million due each of June 30, September 30 and December 12, 2010. The revolving credit facility requires that if any

47

amounts are drawn, they be repaid by December 2008. Prior to that date, funds may be borrowed, repaid and reborrowed under the revolving credit facility without premium or penalty. Letters of credit may be issued under the revolving credit facility.

The tranche B-1 letter of credit/revolving loan facility requires that it be repaid by December 2010. We can borrow revolving loans from the $155 million tranche B-1 letter of credit/revolving loan facility and use that facility to support letters of credit. The tranche B-1 letter of credit/revolving loan facility lenders have deposited $155 million with the administrative agent, who has invested that amount in time deposits. We do not have an interest in any of the funds on deposit. When we draw revolving loans under this facility, the loans are funded from the $155 million on deposit with the administrative agent. When we make repayments, the repayments are redeposited with the administrative agent.

The tranche B-1 letter of credit/revolving loan facility will be reflected as debt on our balance sheet only if we borrow money under this facility or if we use the facility to make payments for letters of credit. We will not be liable for any losses to or misappropriation of any (i) return due to the administrative agent's failure to achieve the return described above or to pay all or any portion of such return to any lender under such facility or (ii) funds on deposit in such account by such lender (other than the obligation to repay funds released from such accounts and provided to us as revolving loans under such facility).

Senior Credit Facility--Interest Rates and Fees. Borrowings under the term loan B facility and the tranche B-1 letter of credit/revolving loan facility bear interest at an annual rate equal to, at our option, either (i) the London Interbank Offering Rate plus a margin of 225 basis points reduced from 300 basis points in February 2005; or (ii) a rate consisting of the greater of the JP Morgan Chase prime rate or the Federal Funds rate plus 50 basis points, plus a margin of 125 basis points reduced from 200 basis points in February 2005. There is no cost to us for issuing letters of credit under the tranche B-1 letter of credit/revolving loan facility, however outstanding letters of credit reduce our availability to borrow revolving loans under this portion of the facility. If a letter of credit issued under this facility is subsequently paid and we do not reimburse the amount paid in full, then a ratable portion of each lender's deposit would be used to fund the letter of credit. We pay the tranche B-1 lenders a fee which is equal to LIBOR plus 225 basis points reduced from 300 basis points in February 2005. This fee is offset by the return on the funds deposited with the administrative agent which earn interest at a per annum rate approximately equal to LIBOR. Outstanding revolving loans reduce the funds on deposit with the administrative agent which in turn reduce the earnings of those deposits and effectively increases our interest expense at a per annum rate equal to LIBOR. The interest margins for borrowings under the term loan B facility and tranche B-1 letter of credit/revolving loan facility will be further reduced by 25 basis points following: the end of each fiscal quarter for which the consolidated leverage ratio is less than 3.0 or at the point our credit ratings are improved to BB- or better by Standard & Poor's (and are rated at least B1 by Moody's) or to Ba3 or better by Moody's (and are rated at least B+ by Standard & Poor's).

Through the first six months of 2005, borrowings under the revolving credit facility bore interest at an annual rate equal to, at our option, either (i) the London Interbank Offering Rate plus a margin of 300 basis points reduced from 325 basis points in March and to be further reduced to 275 basis points in August 2005; or (ii) a rate consisting of the greater of the JP Morgan Chase prime rate or the Federal Funds rate plus 50 to be reduced to 37.5 basis points in August of 2005, plus a margin of 200 reduced from 225 basis points in March and to be further reduced to 175 basis points in August of 2005. Letters of credit issued under the revolving credit facility accrue a letter of credit fee at a per annum rate of 325 basis points for the pro rata account of the lenders under such facility and a fronting fee for the ratable account of the issuers thereof at a per annum rate in an amount to be agreed upon payable quarterly in arrears. The interest margins for borrowings and letters of credit issued under the revolving credit facility are subject to adjustment based on the consolidated leverage ratio (consolidated indebtedness divided by consolidated EBITDA as defined in the senior credit facility agreement) measured at the end of each quarter. The margin we pay on the revolving credit facility is reduced by 25 basis points following each fiscal quarter for which the consolidated leverage ratio is less than 4.0 beginning in March 2005. Since our consolidated leverage ratio was 3.52 as of March 31, 2005, and 3.42 as of June 30, 2005, the margin we pay on the revolving credit facility was reduced by 25 basis points in the second quarter of 2005 and will be further reduced by 25 basis points in the third quarter of 2005. We also pay a commitment fee of 50 basis points on the unused portion of the revolving credit facility. This commitment fee

48

will be reduced by 12.5 basis points during the third quarter of 2005 as our consolidated leverage ratio is less than 3.5.

Senior Credit Facility--Other Terms and Conditions. The amended and restated senior credit facility requires that we maintain financial ratios equal to or better than the following consolidated leverage ratio (consolidated indebtedness divided by consolidated EBITDA), consolidated interest coverage ratio (consolidated EBITDA divided by consolidated cash interest paid), and fixed charge coverage ratio (consolidated EBITDA less consolidated capital expenditures, divided by consolidated cash interest paid) at the end of each period indicated. The financial ratios required under the amended senior credit facility and, the actual ratios we achieved for the first and second quarters of 2005, are shown in the following tables:

The senior credit facility agreement provides: i) the ability to refinance our senior subordinated notes and/or our senior secured notes using the net cash proceeds from the issuance of similarly structured debt; (ii) the ability to repurchase our senior subordinated notes and/or our senior secured notes using the net cash proceeds from issuing shares of our common stock; and (iii) the prepayment of the term loans by an amount equal to 50 percent of our excess cash flow as defined by the agreement.

The senior credit facility agreement also contains restrictions on our operations that are customary for similar facilities, including limitations on:
(i) incurring additional liens; (ii) sale and leaseback transactions (except for the permitted transactions as described in the amendment); (iii) liquidations and dissolutions; (iv) incurring additional indebtedness or guarantees; (v) capital expenditures; (vi) dividends; (vii) mergers and consolidations; and
(viii) prepayments and modifications of subordinated and other debt instruments. Compliance with these requirements and restrictions is a condition for any incremental borrowings under the senior credit facility agreement and failure to meet these requirements enables the lenders to require repayment of any outstanding loans. As of June 30, 2005, we were in compliance with all the financial covenants (as indicated above) and operational restrictions of the facility.

Our senior credit facility does not contain any terms that could accelerate the payment of the facility as a result of a credit rating agency downgrade.

Senior Secured and Subordinated Notes. Our outstanding debt also includes $475 million of 10 1/4 percent senior secured notes due July 15, 2013, in addition to the $500 million of 8 5/8 percent senior subordinated notes due November 15, 2014 described above. We can redeem some or all of the notes at any time after July 15, 2008, in the case of the senior secured notes, and November 15, 2009, in the case of the senior subordinated notes. If we sell certain of our assets or experience specified kinds of changes in control, we must offer to repurchase the notes. We are permitted to redeem up to 35 percent of the senior secured notes with the proceeds of certain equity offerings completed before July 15, 2006 and up to 35 percent of the senior subordinated notes with the proceeds of certain equity offerings completed before November 15, 2007.

49

Our senior secured and subordinated notes require that, as a condition precedent to incurring certain types of indebtedness not otherwise permitted, our consolidated fixed charge coverage ratio, as calculated on a proforma basis, to be greater than 2.25 and 2.00, respectively. We have not incurred any of the types of indebtedness not otherwise permitted by the indentures. The indentures also contain restrictions on our operations, including limitations on: (i) incurring additional indebtedness or liens; (ii) dividends; (iii) distributions and stock repurchases; (iv) investments; (v) asset sales and (vi) mergers and consolidations. Subject to limited exceptions, all of our existing and future material domestic wholly owned subsidiaries fully and unconditionally guarantee these notes on a joint and several basis. In addition, the senior secured notes and related guarantees are secured by second priority liens, subject to specified exceptions, on all of our and our subsidiary guarantors' assets that secure obligations under our senior credit facility, except that only a portion of the capital stock of our and our subsidiary guarantor's domestic subsidiaries is provided as collateral and no assets or capital stock of our direct or indirect foreign subsidiaries secure the notes or guarantees. There are no significant restrictions on the ability of the subsidiaries that have guaranteed these notes to make distributions to us. The senior subordinated notes rank junior in right of payment to our senior credit facility and any future senior debt incurred. As of June 30, 2005, we were in compliance with the covenants and restrictions of these indentures.

Accounts Receivable Securitization. In addition to our senior credit facility, senior secured notes and senior subordinated notes, we also sell some of our accounts receivable. In North America, we have an accounts receivable securitization program with two commercial banks. We sell original equipment and aftermarket receivables on a daily basis under this program. We sold accounts receivable under this program of $82 million and $48 million at June 30, 2005 and 2004, respectively. This program is subject to cancellation prior to its maturity date if we were to (i) fail to pay interest or principal payments on an amount of indebtedness exceeding $50 million, (ii) default on the financial covenant ratios under the senior credit facility, or (iii) fail to maintain certain financial ratios in connection with the accounts receivable securitization program. In January 2005, this program was renewed for 364 days to January 30, 2006 at the existing facility size of $75 million. In March 2005, the program was amended to increase the size to $90 million. In July 2005, the program was again amended to increase the size up to $115 million. We also sell some receivables in our European operations to regional banks in Europe. At June 30, 2005 we sold $66 million of accounts receivable in Europe down from $100 million at June 30, 2004. The arrangements to sell receivables in Europe are not committed and can be cancelled at any time. If we were not able to sell receivables under either the North American or European securitization programs, our borrowings under our revolving credit agreements would increase. These accounts receivable securitization programs provide us with access to cash at costs that are generally favorable to alternative sources of financing, and allow us to reduce borrowings under our revolving credit agreements.

Capital Requirements. We believe that cash flows from operations, combined with available borrowing capacity described above, assuming that we maintain compliance with the financial covenants and other requirements of our loan agreement, will be sufficient to meet our future capital requirements for the following year. Our ability to meet the financial covenants depends upon a number of operational and economic factors, many of which are beyond our control. Factors that could impact our ability to comply with the financial covenants include the rate at which consumers continue to buy new vehicles and the rate at which they continue to repair vehicles already in service, as well as our ability to successfully implement our restructuring plans and offset higher raw material prices. Lower North American vehicle production levels, weakening in the global aftermarket, or a reduction in vehicle production levels in Europe, beyond our expectations, could impact our ability to meet our financial covenant ratios. In the event that we are unable to meet these financial covenants, we would consider several options to meet our cash flow needs. These options could include further renegotiations with our senior credit lenders, additional cost reduction or restructuring initiatives, sales of assets or common stock, or other alternatives to enhance our financial and operating position. Should we be required to implement any of these actions to meet our cash flow needs, we believe we can do so in a reasonable time frame.

We principally use our revolving credit facilities to finance our short-term capital requirements. As a result, we classify any outstanding balances of the revolving credit facilities within our short-term debt even though the revolving credit facility has a termination date of December 13, 2008 and the tranche B-1 letter of credit facility/revolving loan facility has a termination date of December 13, 2010.

If we do not maintain compliance with the terms of our senior credit facility, senior secured notes indenture and senior subordinated debt indenture described above, all amounts under those arrangements could, automatically or at the option of the lenders or other debt holders, become due. Additionally, each of those facilities contains provisions that payment defaults and events that cause, or in some cases permit, acceleration under one facility will constitute a default under the other facility, allowing the acceleration of all amounts due. We currently expect to maintain compliance with terms of all of our various credit agreements for the foreseeable future.

Included in our contractual obligations is the amount of interest to be paid on our long-term debt. As our debt structure contains both fixed and variable rate interest debt, we have made assumptions in calculating the amount of the future interest payments. Interest on our senior secured notes and senior subordinated notes is calculated using the fixed rates of 10 1/4 percent and 8 5/8 percent, respectively. Interest on our variable rate debt is calculated as 225 basis points plus LIBOR of 3.34 percent which was the rate at June 30, 2005. We have assumed that LIBOR will remain unchanged for the outlying years. See "--Capitalization." In addition we have included the impact of our interest rate swaps entered into in April 2004. See "Interest Rate Risk" below.

We have also included an estimate of expenditures required after June 30, 2005 to complete the facilities and projects authorized at December 31, 2004, in which we have made substantial commitments in connections with facilities.

We have not included purchase obligations as part of our contractual obligations as we generally do not enter into long-term agreements with our suppliers. In addition, the agreements we currently have do not specify the volumes we are required to purchase. If any commitment is provided, in many cases the agreements state only the minimum percentage of our purchase requirements we must buy from the supplier. As a result, these purchase obligations fluctuate from year to year and we are not able to quantify the amount of our future obligation.

51

We have not included material cash requirements for taxes as we are a taxpayer in certain foreign jurisdictions but not in domestic locations. Additionally, it is difficult to estimate taxes to be paid as changes in where we generate income can have a significant impact on future tax payments. We have also not included cash requirements for funding pension and postretirement benefit costs. Based upon current estimates we believe we will be required to make contributions between $58 million to $63 million to those plans in 2005, of which approximately $24 million has been contributed as of June 30, 2005. Pension and postretirement contributions beyond 2005 will be required but those amounts will vary based upon many factors, including the performance of our pension fund investments during 2005. In addition, we have not included cash requirements for environmental remediation. Based upon current estimates we believe we will be required to spend approximately $10 million over the next 20 to 30 years. However, due to possible modifications in remediation processes and other factors, it is difficult to determine the actual timing of the payments. See "--Environmental and Other Matters".

We occasionally provide guarantees that could require us to make future payments in the event that the third party primary obligor does not make its required payments. We have not recorded a liability for any of these guarantees. The only third party guarantee we have made is the performance of lease obligations by a former affiliate. Our maximum liability under this guarantee was approximately $4 million at both June 30, 2005 and 2004, respectively. We have no recourse in the event of default by the former affiliate. However, we have not been required to make any payments under this guarantee.

Additionally, we have from time to time issued guarantees for the performance of obligations by some of our subsidiaries, and some of our subsidiaries have guaranteed our debt. All of our existing and future material domestic wholly-owned subsidiaries fully and unconditionally guarantee our senior credit facility, our senior secured notes and our senior subordinated notes on a joint and several basis. The arrangement for the senior credit facility is also secured by first-priority liens on substantially all our domestic assets and pledges of 66 percent of the stock of certain first-tier foreign subsidiaries. The arrangement for the $475 million senior secured notes is also secured by second-priority liens on substantially all our domestic assets, excluding some of the stock of our domestic subsidiaries. No assets or capital stock of our direct or indirect foreign subsidiaries secure these notes. You should also read Note 14 where we present the Supplemental Guarantor Condensed Consolidating Financial Statements.

We have issued guarantees through letters of credit in connection with some obligations of our affiliates. We have guaranteed through letters of credit support for local credit facilities, travel and procurement card programs, and cash management requirements for some of our subsidiaries totaling $26 million. We have also issued $19 million in letters of credit to support some of our subsidiaries' insurance arrangements. In addition, we have issued $3 million in guarantees through letters of credit to guarantee other obligations of subsidiaries primarily related to environmental remediation activities.

Operating Activities

For the six months ended, June 30, 2005, operating activities used $71 million in cash compared to a source of $59 million in cash during the same period last year. For the first six months of 2005, cash used for working capital was $177 million versus $61 million for the first six months of 2004. The discontinuation of accelerated payment programs with three major OE customers in North America was the primary reason for

52

higher year over year receivables balances that resulted in a cash outflow of $200 million, an $87 million increase from last year. Inventory represented a cash outflow of $33 million during the first six months of 2005, an increase of $17 million over the prior year. This primarily resulted from building higher inventories in advance of the selling season, particularly in the aftermarket business units. Accounts payable provided cash of $64 million, slightly up from last year's cash inflow of $60 million. Other current liabilities resulted in a use of $10 million in cash for the first six months of 2005, versus providing a source of $24 million in cash during the same period last year. This change of $34 million was primarily related to severance payments and an increase in pension contributions during the first six months of 2005, as well as last year's increase in accruals for a new aftermarket customer. Cash taxes were a $11 million outflow in the latest six months ending June 30, 2005, compared with a $7 million outflow in the prior year, primarily due to the timing of foreign tax payments.

We had arrangements with three major OE customers in North America under which, in exchange for a discount, payments for product sales are made earlier than otherwise required under existing payment terms. These arrangements reduced accounts receivable by $9 million and $88 million as of June 30, 2005 and December 31, 2004, respectively. All three of these programs were discontinued during the first six months of 2005. To mitigate the impact on our liquidity from the termination of these programs, we supplemented our existing senior credit facility by increasing from $220 million to $300 million the amount of lenders' commitments under the revolving credit facility portion of the senior credit facility. As part of this agreement, we reduced from $180 million to $155 million the amount of lenders' commitments under the tranche B-1 letter of credit/revolving loan facility portion of the senior credit facility.

One of our European subsidiaries receives payment from an OE customer whereby accounts receivable are satisfied through the delivery of negotiable financial instruments. We may collect these financial instruments before their maturity date by either selling them at a discount or using them to satisfy accounts receivable that have previously been sold to a European bank. The reported sales of these financial instruments were no longer included in the account receivables sold beginning in the fourth quarter of 2004. Any of these financial instruments that are not sold are classified as other current assets as they do not meet our definition of cash equivalents. The amount of financial instruments that were collected before their maturity date totaled $25 million at June 30, 2005, compared with $44 million at December 31, 2004.

Investing Activities

Cash used for investing activities was $24 million higher in the first six months of 2005 compared to the same period one year ago. During the first six months of 2005, we used $11 million in cash to acquire the exhaust operations of Gabilan Manufacturing, partially offset by net proceeds from the sale of assets of $3 million. In the first six months of 2004, we received $11 million in cash from the sale of our Birmingham, U.K. facility. Capital expenditures were $63 million in the first six months of 2005 compared to $54 million a year ago. This increase of $9 million in capital expenditures was primarily due to the timing of future OE customer platform launches.

Financing Activities

Cash flow from financing activities was a $4 million outflow in the first six months of 2005 compared to an inflow of $3 million in the same period of 2004. This is primarily attributable to $42 million in cash used to reduce our long-term debt, partially offset by increased borrowings from our revolving credit facility during the six months of 2005.

INTEREST RATE RISK

Our financial instruments that are sensitive to market risk for changes in interest rates are our debt securities. We primarily use our revolving credit facilities to finance our short-term capital requirements. We pay a current market rate of interest on these borrowings. We have financed our long-term capital requirements with long-term debt with original maturity dates ranging from five to ten years.

In April 2004, we entered into three separate fixed-to-floating interest rate swaps with two separate financial institutions. These agreements swapped an aggregate of $150 million of fixed interest rate debt at an

53

annual rate of 10 1/4 percent to floating interest rate debt at an annual rate of LIBOR plus an average spread of 5.68 percent. Each agreement requires semi-annual settlements through July 15, 2013. The LIBOR in effect for these swaps during the course of 2004 resulted in lower interest expense of approximately $3 million for the year ended December 31, 2004. Based on the rate in effect through July 15, 2005 and using the current LIBOR as determined under these agreements of 3.82 percent (which remains in effect until January 15, 2006), these swaps would reduce our 2005 annual interest expense by approximately $2 million compared to having this debt remain fixed. These swaps qualify as fair value hedges in accordance with SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," as amended and as such are recorded on the balance sheet at market value with an offset to the underlying hedged item, which is long-term debt. As of June 30, 2005, the fair value of the interest rate swaps was close to zero and as such did not have a material impact on our financial position. On June 30, 2005, we had $994 million in long-term debt obligations that have fixed interest rates. Of that amount, $489 million is fixed through July 2013 and $500 million through November 2014, while the remainder is fixed over periods of 2005 through 2025. Included in the $489 million is $150 million of long-term debt obligations subject to variable interest rates as a result of our swap agreements. There is also $369 million in long-term debt obligations that have variable interest rates based on a current market rate of interest.

We estimate that the fair value of our long-term debt at June 30, 2005 was about 105 percent of its book value. A one percentage point increase or decrease in interest rates would increase or decrease the annual interest expense we recognize in the income statement and the cash we pay for interest expense by about $3 million after tax, excluding the effect of the interest rate swaps we completed in April 2004. A one percentage point increase or decrease in interest rates on the swaps we completed in April 2004 would increase or decrease the annual interest expense we recognize in the income statement and the cash we pay for interest expense by approximately $1 million after tax.

OUTLOOK

Continued higher steel pricing, volatile oil prices and rising interest rates make this an uncertain and challenging environment for automotive suppliers. North American OE light vehicle production levels for 2004 were 15.8 million units. Current estimates for 2005 indicate that North American OE light vehicle production levels will be lower than 2004 at 15.6 million units. We continue to remain very cautious about the outlook for North American production rates due to recent and anticipated future production cuts by the largest North American automakers. There is uncertainty about the ability of current incentive programs to drive future demand, and how long the North American automakers will be willing to offer this level of incentives. We believe that new product launches and our position on top-selling platforms, along with increasing market positions with Toyota, Honda and Nissan, will help us to offset pressures from lower North American production rates. Western Europe light vehicle production volumes grew about one percent during 2004 to 16.6 million units. Expectations for 2005 indicate production will drop to 16.2 million units. We saw a strong increase in heavy-duty truck production rates during 2004. Production rates are expected to increase another 16 to 19 percent in 2005. Although heavy-duty business represents a small percentage of our overall revenues, this should benefit our North American operations. In the global aftermarket, issues that have impacted revenues in the past will likely continue to be a challenge in 2005. In Asia, the Chinese government's restraint on lending remains a negative influence on consumer spending for automobiles. This combined with Volkswagen's recent market share decline in China is expected to continue to negatively impact our revenues in China. We believe that new joint ventures to serve Ford and BMW, and a growing relationship with General Motors in China will improve our position in the Asia Pacific region. Heightened competition in the European aftermarket, weaker export sales due to the comparatively strong euro and longer product replacement cycles are expected to have a continued impact on volumes. We saw signs of sales stabilization in the North American aftermarket exhaust business unit during 2004 and some improvements in revenues during the first half of 2005. We are cautiously optimistic that these North American aftermarket conditions will continue in 2005. We also plan to continue our efforts to increase new and existing sales in the North American aftermarket ride control business unit.

54

These factors make us cautious concerning the outlook for the remainder of 2005. However, we believe our diversified customer base, geographies, product lines, platforms and markets provide the opportunity to offset specific declines in any one area. We are also benefiting from environmental legislation and consumer safety concerns that drive higher content for exhaust and ride control suppliers with innovative product solutions.

We continue to focus on mitigating the impact of higher costs by completing the restructuring initiative announced in the fourth quarter of last year, which is expected to generate $20 million in annual savings; improving manufacturing efficiency with Lean; generating at least $20 million in Six Sigma savings; and capitalizing on our anticipated increase in 2005 revenues over those we achieved in 2004. Lower interest expense as a result of our debt refinancing in the fourth quarter of 2004 and amendments to our senior credit facility in the first quarter of 2005 will also help mitigate the impact. In addition, as we move to the back half of the year we are not expecting a significant impact on EBIT year--over-year from higher steel costs, net of other material cost savings and recovery from customers, as a result of a variety of offsetting cost reduction initiatives.

ENVIRONMENTAL AND OTHER MATTERS

We are subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which we operate. We expense or capitalize, as appropriate, expenditures for ongoing compliance with environmental regulations that relate to current operations. We expense expenditures that relate to an existing condition caused by past operations and that do not contribute to current or future revenue generation. We record liabilities when environmental assessments indicate that remedial efforts are probable and the costs can be reasonably estimated. Estimates of the liability are based upon currently available facts, existing technology, and presently enacted laws and regulations taking into consideration the likely effects of inflation and other societal and economic factors. We consider all available evidence including prior experience in remediation of contaminated sites, other companies' cleanup experiences and data released by the United States Environmental Protection Agency or other organizations. These estimated liabilities are subject to revision in future periods based on actual costs or new information. Where future cash flows are fixed or reliably determinable, we have discounted the liabilities. All other environmental liabilities are recorded at their undiscounted amounts. We evaluate recoveries separately from the liability and, when they are assured, recoveries are recorded and reported separately from the associated liability in our financial statements.

As of June 30, 2005, we are designated as a potentially responsible party in one Superfund site. We have estimated our share of the remediation costs for this site to be less than $1 million in the aggregate. In addition to the Superfund site, we may have the obligation to remediate current or former facilities, and we estimate our share of remediation costs at these facilities to be approximately $10 million. For the Superfund site and the current and former facilities, we have established reserves that we believe are adequate for these costs. Although we believe our estimates of remediation costs are reasonable and are based on the latest available information, the cleanup costs are estimates and are subject to revision as more information becomes available about the extent of remediation required. At some sites, we expect that other parties will contribute to the remediation costs. In addition, at the Superfund site, the Comprehensive Environmental Response, Compensation and Liability Act provides that our liability could be joint and several, meaning that we could be required to pay in excess of our share of remediation costs. Our understanding of the financial strength of other potentially responsible parties at the Superfund site, and of other liable parties at our current and former facilities, has been considered, where appropriate, in our determination of our estimated liability.

We believe that any potential costs associated with our current status as a potentially responsible party in the Superfund site, or as a liable party at our current or former facilities, will not be material to our results of operations or consolidated financial position.

From time to time we are subject to product warranty claims whereby we are required to bear costs of repair or replacement of certain of our products. Warranty claims may range from individual customer claims to full recalls of all products in the field. See Note 6 to our consolidated financial statements included under Item 1 for information regarding our warranty reserves.

55

We also from time to time are involved in legal proceedings, claims or investigations that are incidental to the conduct of our business. Some of these proceedings allege damages against us relating to environmental liabilities (including toxic tort, property damage and remediation), intellectual property matters (including patent, trademark and copyright infringement, and licensing disputes), personal injury claims (including injuries due to product failure, design or warnings issues, and other product liability related matters), taxes, employment matters, and commercial or contractual disputes, sometimes related to acquisitions or divestitures. For example, one of our Chinese joint ventures is currently under investigation by local customs officials related to whether the joint venture applied the proper tariff code to certain of its imports. We vigorously defend ourselves against all of these claims. In future periods, we could be subjected to cash costs or non-cash charges to earnings if any of these matters is resolved on unfavorable terms. However, although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claim, we do not expect that these legal proceedings or claims will have any material adverse impact on our future consolidated financial position or results of operations. In addition, we are subject to a number of lawsuits initiated by a significant number of claimants alleging health problems as a result of exposure to asbestos. Many of these cases involve significant numbers of individual claimants. However, only a small percentage of these claimants allege that they were automobile mechanics who were allegedly exposed to our former muffler products and a significant number appear to involve workers in other industries or otherwise do not include sufficient information to determine whether there is any basis for a claim against us. We believe, based on scientific and other evidence, it is unlikely that mechanics were exposed to asbestos by our former muffler products and that, in any event, they would not be at increased risk of asbestos-related disease based on their work with these products. Further, many of these cases involve numerous defendants, with the number of each in some cases exceeding 200 defendants from a variety of industries. Additionally, the plaintiffs either do not specify any, or specify the jurisdictional minimum, dollar amount for damages. As major asbestos manufacturers continue to go out of business, we may experience an increased number of these claims. We vigorously defend ourselves against these claims as part of our ordinary course of business. In future periods, we could be subject to cash costs or non-cash charges to earnings if any of these matters is resolved unfavorably to us. To date, with respect to claims that have proceeded sufficiently through the judicial process, we have regularly achieved favorable resolution in the form of a dismissal of the claim or a judgment in our favor. Accordingly, we presently believe that these asbestos-related claims will not have a material adverse impact on our future financial condition or results of operations.

EMPLOYEE STOCK OWNERSHIP PLANS

We have established Employee Stock Ownership Plans for the benefit of our employees. Under the plans, subject to limitations in the Internal Revenue Code, participants may elect to defer up to 50 percent of their salary through contributions to the plan, which are invested in selected mutual funds or used to buy our common stock. We currently match in cash 50 percent of each employee's contribution up to eight percent of the employee's salary. We recorded expense for these matching contributions of approximately $3 million for each of the six months ended June 30, 2005 and 2004, respectively. All contributions vest immediately.

OTHER

As required under current rules, our chief executive officer provided to the New York Stock Exchange, the Pacific Stock Exchange and the Chicago Stock Exchange the annual CEO certification regarding Tenneco Automotive's compliance with those stock exchanges' corporate governance listing requirements. There were no qualifications to these certifications.

[SRP]


Tenneco Automotive Inc. Supplemental Retirement Plan

The Tenneco Automotive Inc. Supplemental Retirement Plan (the "Plan") is hereby established by Tenneco Automotive Inc. (the "Company") effective January 1, 2005.

Retirement Plan for Salaried Employees (the "Retirement Plan") as a result of the imposition of the limitations contained in the Internal Revenue Code of 1986, as amended (the "Code"). The portion of the Plan that provides for benefits limited by Code
Section 415 is maintained as an "excess benefit plan" as described in Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). The other benefits provided for under the Plan are only available to a "select group of management or highly compensated employees" as determined by the Compensation/Nominating/Governance Committee of the Board of Directors of the Company (the "Committee"), and the portion of the Plan providing such benefits is intended to satisfy the ERISA exemption requirements for a plan limited to such group. Capitalized terms not defined herein shall have the meaning ascribed to such term in the Retirement Plan.

Participant; provided, that the calendar year including his or her termination or retirement shall be included if such event follows the payment of regular bonuses for that year; and provided, that bonuses and salary, respectively, deferred at the election of the Participant shall be counted only in the year that they would have been paid absent such election, and provided, further, that the foregoing language shall be applied to count bonuses which relate to a calendar year as paid in that year, for example, 2005 bonuses will be counted in 2005 notwithstanding the fact that they are actually paid in 2006; and

(b) is the total benefit that is payable under the Retirement Plan, the Tenneco Retirement Plan (and any successor thereto) and the Tenneco Automotive Inc. Supplemental Executive Retirement Plan.

Notwithstanding the foregoing, if, except as otherwise provided in writing, an employee is granted credit for purposes of benefit accrual under the Retirement Plan for service rendered prior to the time that the employee became a participant in the Retirement Plan, such employee shall be credited with such service under this Plan only if and to the extent determined by the Committee. Unless otherwise provided in writing, no benefit shall be payable under the Plan unless a benefit also is payable under the Retirement Plan.

Cash bonus means only cash bonuses paid under the TAVA Plan and other cash bonuses as the Committee determines.

4. Form of Benefit.

The actuarial factors set forth in the Retirement Plan shall be used to compute Plan Benefits, provided that, for purposes of a lump sum payment, the interest rate used shall be the annual rate of interest on 30 year Treasury securities as specified by the IRS for the second calendar month preceding the first day of the plan year during which the annuity starting date occurs, and the applicable mortality table described in Rev. Rul. 95-6, 1995-1 C.B. (page 80), or in such other formal guidance as may be issued from time to time by the IRS.

11. Amendment and Discontinuance.

The Company reserves the right, by action of the Committee, to amend or discontinue the Plan. However, no such amendment or discontinuance shall impair or adversely affect any benefits accrued under this Plan as of the date of such action.

Exhibit 10.46

TENNECO AUTOMOTIVE INC.
INCENTIVE DEFERRAL PLAN


TENNECO AUTOMOTIVE INC. INCENTIVE DEFERRAL PLAN

1. PURPOSE

Effective January 1, 2005, Tenneco Automotive Inc. (the "Company") hereby establishes the Tenneco Automotive Inc. Incentive Deferral Plan (the "Plan"). The purpose of the Plan is to provide directors and a select group of management or highly compensated employees of the Company and its subsidiaries and affiliates (hereinafter collectively referred to as the "Company") an opportunity to defer compensation received by them from the Company in accordance with the terms and conditions set forth herein.

2. ADOPTION AND ADMINISTRATION

The Plan shall be administered by the Compensation/Nominating/Governance Committee of the Board of Directors of the Company (the "Committee"). The Committee shall have the sole and complete authority and discretion to interpret the terms and provisions of the Plan and to adopt, alter and repeal such administrative rules, regulations and practices governing the operation of the Plan, and to determine facts under the Plan as it shall from time to time deem advisable.

3. ELIGIBILITY

Directors and executive incentive level U.S. participants in the Company's Value Added ("TAVA") Incentive Compensation Plan shall be eligible to participate in the Plan. Further, any person who had an account balance in the Tenneco Automotive Inc. Deferred Compensation Plan may participate in this Plan.

Persons eligible to participate in the Plan shall be referred to as "Participant" or "Participants" as the case may be.

4. ELECTION TO DEFER

A Participant may elect in writing to defer receipt of all or a specified portion of his or her bonuses or incentive compensation to be received with respect to a calendar year ("Deferral Election"); provided, however, that any election by a Participant who is subject to the reporting and short swing profits liability provisions of Section 16 of the Securities and Exchange Act of 1934, as amended, including an election relating to the form of distribution or to defer income into an "Automotive stock index account" pursuant to Section 6 of the Plan, shall not be effective until such election and the transactions contemplated thereby shall have been specifically approved by the Committee to the extent such approval is required to avoid liability under Section 16 of the Securities and Exchange Act of 1934 and the regulations thereunder. Once received by the Committee, a Deferral Election cannot be revoked. A Deferral Election (including Committee approval) must be made prior to June 30 of the calendar year in which the bonus or incentive compensation will be awarded. A Participant must make a separate Deferral Election with respect to each calendar year of participation in the Plan. A new Participant in the Plan shall have 30 days following his or her notification by the Committee of his or her eligibility to participate in the Plan to make a Deferral Election with respect to bonus or incentive


compensation to be awarded within that calendar year. Amounts deferred under the Plan shall be referred to as the "Deferred Amounts."

5. OUTSIDE DIRECTORS

Directors who are not employees of the Company or its subsidiaries (hereinafter referred to as "Outside Directors") will receive as part of their compensation for service on the Company's Board of Directors sixty (60) percent of their annual retainer fee in the form of credits deferred subject to the terms of this Plan in the Automotive stock index account. Amounts credited to the Automotive stock index account under this Section 5 will be settled either in cash or, if the Company so elects, shares of the Company's common stock and will be offered under the Company's principal equity incentive plan then in effect.

6. ESTABLISHMENT OF DEFERRED COMPENSATION ACCOUNT

At the time of a Participant's initial Deferral Election, the Company shall establish a memorandum account (a "Deferred Compensation Account") for such Participant on its books. The Deferred Amount shall be credited to the Participant's Deferred Compensation Account as of the day on which the Participant would otherwise be entitled to receive the bonus or incentive compensation. Any required withholding for taxes (e.g. Social Security taxes) on the Deferred Amount shall be made from other compensation of the Participant. Adjustments as provided below, shall be made to the Participant's Deferred Compensation Account.

7. ADJUSTMENTS TO DEFERRED AMOUNTS

The Committee shall credit the balance of the Participant's Deferred Compensation Account with an earnings factor. The earnings factor will equal the amount the Participant's Deferred Compensation Account would have earned if it had been invested in the investment options listed below. The Participant is permitted to select the investment option used to determine the earnings factor and may change the selection at any time. The Participant may choose more than one investment option in increments of at least one (1) percent. The Company reserves the right to change or amend any of the investment options at any time. The investment options used to determine the earnings factor are:

(a) The prime rate of interest as reported by JPMorgan Chase Bank at the first day of each calendar month.

(b) Automotive stock index account - the amount of deferral will be invested in Tenneco Automotive Inc. stock equivalent unit account. Any investment in this account will be measured solely by the performance of the Company's common stock (including dividends that will be reinvested). Amounts credited to this account will be settled either in cash or, if the Company so elects, shares of the Company's common stock and will be offered under the Company's principal equity incentive plan then in effect.

2

(c) The return for the following investment funds:

(i) JPMorgan Chase Prime Rate Fund

(ii) Putnam Bond Index Fund

(iii) Putnam S&P 500 Index Fund

The Company is under no obligation to acquire or provide any of the investments designated by a Participant, and any investments actually made by the Company will be made solely in its name and will remain its property.

The crediting of an earnings factor shall occur so long as there is a balance in the Participant's Deferred Compensation Account regardless of whether the Participant has terminated employment.

8. PAYMENT OF DEFERRED AMOUNTS

(a) Subject to the subsection (b) below, a Participant's Deferred Amount shall be paid in a single lump sum payment to the Participant, or the Participant's beneficiary, as soon as practicable after:

(i) the Participant's death,
(ii) the termination of the Participant's employment or service as a director, or
(iii) the date specified in the applicable Deferral Election made by the Participant.

(b) Notwithstanding Section 8(a), with respect to any Participant who is a "key employee" as defined by Section 409A(a)(2)(B)(i) of the Code, payment of such Participant's Deferred Amount shall be made no earlier than six months from Participant's separation from service with the Company.

9. TERMINATION OF PARTICIPATION IN 2005

If a Participant separates from service with the Company in 2005, such Participant may elect, in a writing filed with the Committee, to terminate participation in the Plan and revoke any Deferral Election for 2005. Any amounts would be payable to the Participant and subject to immediate taxation.

3

10. PARTICIPANT REPORTS

The Committee shall provide a statement to the Participant quarterly concerning the status of his or her Deferred Compensation Account.

11. TRANSFERABILITY OF INTERESTS

During the period of deferral, all Deferred Amounts shall be considered as general assets of the Company for use as it deems necessary and shall be subject to the claims of its creditors. The rights and interests of a Participant during the period of deferral shall be those of a general unsecured creditor except that such Participant's rights and interests may not be reached by the creditors of the Participant or the Participant's beneficiary, or anticipated, assigned, pledged, transferred or otherwise encumbered except in the event of the death of the Participant, and then only by will or the laws of descent and distribution.

12. AMENDMENT, SUSPENSION AND TERMINATION

The Company, at any time, through action of the Committee, may amend, suspend or terminate the Plan or any portion thereof in such manner and to such extent as it may deem advisable and in its best interests. No amendment, suspension and termination shall reduce the Deferred Amount then credited to a Participant's Deferred Compensation Account.

13. UNFUNDED OBLIGATION

The Plan shall not be funded; no trust, escrow or other provisions shall be established to secure payments due under the Plan; and the Plan shall be regarded as unfunded for purposes of the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code. A Participant shall be treated as a general, unsecured creditor at all times under the Plan, and shall have no rights to any specific assets of the Company. All amounts credited to the memorandum accounts of the Participants will remain general assets of the Company and shall be payable solely from the general assets of the Company.

14. NO RIGHT TO EMPLOYMENT OR OTHER BENEFITS

Nothing contained herein shall be construed as conferring upon any Participant the right to continue in the employ of the Company. Any compensation deferred and any payments made under this Plan shall not be included in creditable compensation in computing benefits under any employee benefit plan of the Company except to the extent expressly provided therein.

15. DISPUTE RESOLUTION

By participating in the Plan, the Participant agrees that any dispute arising under the Plan shall be resolved by binding arbitration in Lake Forest, Illinois under the rules of the American Arbitration Association and that there will be no remedy besides the disputed deferred compensation amount in issue.

4

16. EFFECTIVE DATE

The effective date of this Plan is January 1, 2005 (the "Effective Date").

IN WITNESS WHEREOF, the Company has caused the Plan to be executed on its behalf by its respective officers thereunder duly authorized, as of the Effective Date.
