THIRD QUARTER 2004 ADJUSTMENTS:

     -    Restructuring related expenses of $2 million pre-tax, or 4-cents per
          diluted share;

                                     -More-



                                      -2-


     -    Tax benefit of $1 million, or 2-cents per diluted share.

The quarterly revenue of $1.096 billion was the company's 14th consecutive
quarter of year-over-year revenue growth. The increase over $996 million in
third quarter 2004 was driven by higher global original equipment (OE)
production volumes and $19 million in favorable currency.

Tenneco Automotive's performance in the third quarter was driven by its platform
mix with products on strong selling vehicles globally; improved aftermarket ride
control volumes in North America and Europe; benefits from the company's ongoing
manufacturing efficiency programs; and reduced costs through tight controls on
discretionary spending. These efforts helped offset the negative impact of
higher material costs and higher transportation costs due to fuel surcharges.

"We delivered another solid quarter in spite of very challenging market
conditions," said Mark P. Frissora, chairman, CEO and president, Tenneco
Automotive. "Our ability to execute on consistent strategies for growing the
top-line while managing costs is proving successful despite lower OE industry
production volumes in North America and Europe, our two largest markets, and the
impact of higher material and fuel costs globally."

Cash generated by operations in the quarter was $33 million, which on a
year-over-year comparison basis includes a $9 million negative impact from the
discontinuation of General Motor's advanced payment program and a $20 million
cash outflow for incremental pension contributions. Cash generated by operations
was $76 million for the same period one year ago. The remaining difference in
the year-over-year comparison was due to working capital requirements -
primarily in accounts receivables - to support approximately $100 million in
higher revenue in the quarter.

At quarter-end, total debt was $1.429 billion, compared with $1.423 billion the
previous year. Debt net of cash was $1.340 billion versus $1.220 billion a year
ago, primarily due to the discontinuation of advance payment programs by General
Motors, Ford and DaimlerChrysler, which increased debt by $103 million over the
last 12 months. Debt net of cash at June 30, 2005 was $1.346 billion.

During the quarter, Tenneco resolved a commercial lawsuit that is recorded as
other income and settled a customer issue, which is netted against revenue. The
net of these transactions had no financial impact on the company's operating
results.

The company's gross margin decreased 1.2 percentage points year-over-year to
18.9%. Gross margin was negatively impacted by higher steel costs, fuel
surcharges on transportation costs and a shifting business mix between Europe
and North America, and between OE and aftermarket businesses. Additionally,
resolution of the OE customer issue mentioned above reduced gross margin. These
factors offset savings and improved efficiencies from Lean manufacturing, Six
Sigma and other cost reduction initiatives.

Total steel cost increases in the third quarter were $33 million, which were
largely offset by the company's cost reduction efforts, including SGA&E
restructuring savings, material cost savings, Six Sigma program savings and Lean
manufacturing efficiencies as well as steel cost recovery from OE and
aftermarket customers. Based on the company's efforts to offset increased steel
costs and trends in the steel market, the company doesn't currently anticipate a
significant year-over-year impact on operating results through the remainder of
2005.



                                      -3-


Sales, General, Administrative and Engineering (SGA&E) expense in the quarter
was 10.8% of sales versus 11.3% a year ago. SGA&E improvement was driven by
higher revenues, cutbacks on discretionary spending and benefits from previously
announced restructuring programs.

Tenneco Automotive continued to outperform its bank debt covenants in the
quarter. At September 30, the leverage ratio was 3.39, lower than the maximum
limit of 4.50; the fixed charge ratio was 2.05, exceeding the minimum ratio of
1.10; and the interest coverage ratio was 3.12, exceeding the minimum ratio of
2.00.

NORTH AMERICA

     -    North American OE revenue was up 9% to $369 million, versus $338
          million a year ago. Excluding the impact of currency and catalytic
          converter pass-through sales, revenue was up 11%, outperforming a
          light vehicle market production decline of 2%. The increase was driven
          by the company's platform mix with products on strong selling
          vehicles.

     -    North American aftermarket revenue was $133 million, up 5%
          year-over-year. Stronger ride control volumes and price increases in
          both product lines helped offset lower emission control volumes.

     -    EBIT for North American operations was $37 million, versus $31 million
          in third quarter 2004. Stronger OE volumes and manufacturing
          efficiencies more than offset unrecovered steel costs, higher
          advertising costs to support the company's ride control aftermarket
          product lines and the launch costs for its new line of aftermarket
          brake products.

EUROPE, SOUTH AMERICA, INDIA

     -    European OE revenue was $341 million, versus $305 million a year ago.
          Adjusted for favorable currency, catalytic converter pass-through
          sales and a change in reporting for a customer contract, revenue was
          up 14%. The year-over-year improvement - despite a market production
          decline of 1% - was driven by the continued ramp up of new launches
          and a favorable platform mix with product on many of the better
          selling vehicles.

     -    European aftermarket revenue was $97 million, versus $94 million the
          previous year. The 3% improvement was primarily due to stronger ride
          control volumes and price increases in both product lines.

     -    South America and India revenue was $62 million, including $8 million
          in favorable currency, compared with $45 million a year ago. Stronger
          OE volumes drove the increase.

     -    EBIT for Europe, South America and India was $9 million, versus $10
          million in third quarter 2004. The EBIT decrease was the result of
          currency transactional losses with a $2 million negative impact,
          manufacturing inefficiencies due to inventory reductions in the
          quarter, costs for implementing a resource planning system for the
          company's European emission control business and a reserve increase
          related to a pending legal settlement.

     -    Third quarter 2004 and 2005 EBIT results include $2 million in
          restructuring related expenses.

ASIA PACIFIC

     -    Asia operations generated $38 million in revenue, versus $37 million a
          year ago.

     -    Australian revenue increased to $56 million from $50 million the
          previous year, largely driven by $4 million in favorable currency.

     -    EBIT for Asia Pacific operations was $4 million, up from $3 million a
          year ago. EBIT was up despite OE revenue weakness in China and
          investments to increase Tenneco's aftermarket presence there.

YEAR-TO-DATE RESULTS

Through the first nine months of the year, Tenneco Automotive reported net
income of $50 million, or $1.11 per diluted share, versus net income of $34
million, or 78-cents per diluted share for the first nine months of 2004. On an
adjusted basis, year-to-date 2005 net income was $56 million, or $1.24 per
diluted share, versus adjusted net income of $44 million, or $1.01 per diluted
share for the same period one year ago.

Year-to-date EBIT was $177 million, compared with EBIT of $153 million for the
first nine months of 2004. Adjusted EBIT was $184 million versus $177 million a
year ago. Year-to-date 2005 EBITDA was $311 million, compared with $284 million
a year ago, and adjusted EBITDA was $318 million, versus adjusted EBITDA of $308
million for the same period a year ago.

OUTLOOK

"We do not expect an immediate turnaround in OE production rates in North
America or Europe, and we are closely monitoring the aftermarket in those
regions for a potential drop in consumer spending on vehicle maintenance due to
higher fuel prices. This landscape, coupled with continuing increases in
material costs and the impact of higher fuel costs on our transportation
expenses, creates a tough operating environment going forward," Frissora said.
"As a result, we will continue to focus on those areas within our
control--namely executing with discipline on the fundamentals and maintaining a
relentless focus on costs. We should also continue to benefit from our balance
and diversification in terms of products, markets served and customers. Finally,
we will capitalize on opportunities to win incremental OE and aftermarket
business from our competitors."

ability to receive regulatory approvals and the timing of such approvals; (vii)
changes in capital availability or costs, including increases in the company's
costs of borrowing (i.e., interest rate increases), the amount of the company's
debt, the ability of the company to access capital markets and the credit
ratings of the company's debt; (viii) the cost and outcome of existing and any
future legal proceedings, and compliance with changes in regulations, including
environmental regulations; (ix) workforce factors such as strikes or labor
interruptions; (x) the company's ability to develop and profitably commercialize

(1)  Generally Accepted Accounting Principles

(2)  EBITDA represents income before interest expense, income taxes, minority
     interest and depreciation and amortization. EBITDA is not a calculation
     based upon generally accepted accounting principles. The amounts included
     in the EBITDA calculation, however, are derived from amounts included in
     the historical statements of income data. In addition, EBITDA should not be
     considered as an alternative to net income or operating income as an
     indicator of the company's operating performance, or as an alternative to
     operating cash flows as a measure of liquidity. Tenneco Automotive has
     presented EBITDA because it regularly reviews EBITDA as a measure of the
     company's performance. In addition, Tenneco Automotive believes its debt
     holders utilize and analyze our EBITDA for similar purposes. Tenneco
     Automotive also believes EBITDA assists investors in comparing a company's
     performance on a consistent basis without regard to depreciation and
     amortization, which can vary significantly depending upon many factors.
     However, the EBITDA measure presented may not always be comparable to
     similarly titled measures reported by other companies due to differences in
     the components of the calculation.

(2)  Tenneco Automotive presents the above reconciliation of GAAP to non-GAAP
     earnings measures in order to reflect the results for the third quarters of
     2005 and 2004 in a manner that allows a better understanding of the results
     of operational activities separate from the financial impact of decisions
     made for the long-term benefit of the company. Adjustments similar to the
     ones reflected above have been recorded in earlier periods, and similar
     types of adjustments can reasonably be expected to be recorded in future
     periods. Using only the non-GAAP earnings measures to analyze earnings
     would have material limitations because its calculation is based on the
     subjective determinations of management regarding the nature and
     classification of events and circumstances that investors may find
     material. Management compensates for these limitations by utilizing both
     GAAP and non-GAAP earnings measures reflected above to understand and
     analyze the results of the business. The company believes investors find
     the non-GAAP information helpful in understanding the ongoing performance
     of operations separate from items that may have a disproportionate positive
     or negative impact on the company's financial results in any particular
     period.

(3)  EBITDA represents income before interest expense, income taxes, minority
     interest and depreciation and amortization. EBITDA is not a calculation
     based upon generally accepted accounting principles. The amounts included
     in the EBITDA calculation, however, are derived from amounts included in
     the historical statements of income data. In addition, EBITDA should not be
     considered as an alternative to net income or operating income as an
     indicator of the company's operating performance, or as an alternative to
     operating cash flows as a measure of liquidity. Tenneco Automotive has
     presented EBITDA because it regularly reviews EBITDA as a measure of the
     company's performance. In addition, Tenneco Automotive believes its debt
     holders utilize and analyze our EBITDA for similar purposes. Tenneco
     Automotive also believes EBITDA assists investors in comparing a company's
     performance on a consistent basis without regard to depreciation and
     amortization, which can vary significantly depending upon many factors.
     However, the EBITDA measure presented may not always be comparable to
     similarly titled measures reported by other companies due to differences in
     the components of the calculation.

     company's performance. In addition, Tenneco Automotive believes its debt
     holders utilize and analyze our EBITDA for similar purposes. Tenneco
     Automotive also believes EBITDA assists investors in comparing a company's
     performance on a consistent basis without regard to depreciation and
     amortization, which can vary significantly depending upon many factors.
     However, the EBITDA measure presented may not always be comparable to
     similarly titled measures reported by other companies due to differences in
     the components of the calculation.

Tenneco Automotive presents the above reconciliation of revenues in order to
reflect the trend in the company's sales, in various product lines and
geographical 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. While
Tenneco Automotive's original equipment customers assume the risk of this
volatility, it impacts reported revenue. Excluding pass-through catalytic
converter sales removes this impact. Tenneco Automotive uses this information to
analyze the trend in revenues before these factors. Tenneco Automotive believes
investors find this information useful in understanding period to period
comparisons in the company's revenues.

(a)  Beginning in the second quarter of 2005, Tenneco Automotive changed its
     accounting for a customer contract in its European OE Ride Control unit.
     The cost of sales for this contract are now netted against the revenues,
     reducing reported revenues and cost of sales. In the third quarter of 2004,
     Tenneco Automotive recorded $15 million in revenues for this contract.

Tenneco Automotive presents the above reconciliation of revenues in order to
reflect the trend in the company's sales, in various product lines and
geographical 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. While
Tenneco Automotive's original equipment customers assume the risk of this
volatility, it impacts reported revenue. Excluding pass-through catalytic
converter sales removes this impact. Tenneco Automotive uses this information to
analyze the trend in revenues before these factors. Tenneco Automotive believes
investors find this information useful in understanding period to period
comparisons in the company's revenues.

(a)  Beginning in the second quarter of 2005, Tenneco Automotive changed its
     accounting for a customer contract in its European OE Ride Control unit.
     The cost of sales for this contract are now netted against the revenues,
     reducing reported revenues and cost of sales. In the second and third
     quarters of 2004, Tenneco Automotive recorded $30 million in revenues for
     this contract.
