      TENNECO AUTOMOTIVE REPORTS BETTER THAN EXPECTED THIRD QUARTER RESULTS

-   Company reports a net loss of $2 million, or 6-cents per diluted share, on
    reduced revenue of $817 million, beating First Call estimates;
-   Company improves liquidity and reduces net debt by $111 million in the third
    quarter;
-   Working capital improves $152 million year-over-year;
-   North American and European aftermarket businesses improve profitability.


LAKE FOREST, ILLINOIS, OCTOBER 24, 2001 - Tenneco Automotive (NYSE: TEN)
reported a net loss of $2 million, or 6-cents per diluted share, for the third
quarter versus net income of $5 million, or 15-cents per diluted share, one year
ago. Despite lower earnings, the company continued to successfully generate cash
and reduced its net debt by $111 million in the quarter. Reductions in working
capital contributed $87 million in cash to the third quarter performance. The
quarter end working capital balance, before factoring, improved $152 million
year-over-year, and as a percent of annual sales improved four percentage points
over last year to 10.7 percent. The company had $92 million in cash and zero
borrowings under its $500 million revolving bank credit facility at the end of
the quarter.






"We are encouraged by our cash performance this quarter, and continued
aftermarket margin improvement, particularly in light of difficult market
conditions," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "Our
entire organization is focused on generating cash in order to reduce debt, which
is our primary goal. Our success in improving working capital and maintaining
rigorous cost and spending reductions is driving these cash results in a down
market."

Results for the third quarter 2001 include a benefit related to a change in the
effective tax rate, which reduced the net loss by $1 million or 3-cents per
share. Results for the third quarter 2000 included charges for a stock option
buy-back, reversal of a reserve for transaction costs related to the 1999
spin-off of Pactiv, and a charge for early retirement of long-term debt, which
in total reduced income by $4 million, or 8-cents per share. Before these items,
the third quarter 2001 loss was $3 million, or 9-cents per diluted share versus
income of $9 million, or 23-cents per diluted share in the third quarter of
2000.

The company's revenue and profitability continued to be impacted during the
quarter by softening volumes, volatile production rates in the North American
original equipment sector, currency fluctuations, and a slumping global economy.
The company reported revenue for the quarter of $817 million, a 6 percent
decline compared with $865 million in the third quarter of 2000. Adjusted for
pass-through sales for catalytic converters, revenue decreased 11 percent.
EBITDA for the quarter, before previously discussed




items, was $75 million compared with $90 million the previous year, a 17 percent
decline. Currency fluctuations, primarily in North America, lowered the
company's earnings for the quarter by $6 million, or 10-cents per share.

"While we are pleased with our ability to control costs in the short-term, we
are even more encouraged by opportunities we are identifying as longer-term
fundamental changes to our manufacturing, distribution, and supply chain
operations," said Frissora. "We are developing initiatives aimed at addressing
standardization and efficiency issues as well as better aligning our
organization with future market needs. This comprehensive evaluation began
earlier this year and, subject to obtaining the necessary approvals, we expect
to implement a company-wide program over the next four years to optimize our
global distribution and manufacturing footprint."

The company reported the following geographical results:

NORTH AMERICA

North American original equipment revenue decreased 6 percent during the quarter
to $295 million versus $315 million in the third quarter of 2000. Excluding
pass-through sales, revenue decreased 15 percent. North American aftermarket
revenue decreased 3 percent to $145 million from $149 million in the previous
year.

North American EBIT declined to $23 million compared with $29 million in the
third quarter of 2000. SGA&E savings and aftermarket pricing increases were more
than




offset by the negative impact of lower volumes, currency fluctuations in Mexico
and Canada, and expenses associated with launching business with a major new
aftermarket customer. Despite slightly lower revenues, the North American
aftermarket continued to improve its profitability, posting a 90 percent
year-over-year operating margin improvement in the third quarter.

EUROPE

The company reported European original equipment revenue of $221 million for the
quarter, a 2 percent increase over third quarter 2000 revenue of $216 million.
Excluding pass-through sales, revenue decreased 7 percent. European aftermarket
revenue declined 15 percent to $81 million versus $95 million in the third
quarter of 2000.

European EBIT was $9 million for the quarter, compared with $14 million reported
in the third quarter of 2000. The results were driven by lower revenues,
currency devaluation, and higher expenses related to engineering for new
platforms, which more than offset SGA&E savings and aftermarket price increases.
Overall, the European aftermarket improved its earnings year-over-year by 43
percent, and its margins by 68 percent.

REST OF WORLD

The company's Australian operations reported revenue of $27 million for the
quarter, down from $33 million reported in the third quarter of 2000. Revenue
for the quarter would have only decreased by $2 million year-over-year if
currency exchange rates had been the same in the third quarter of 2001 as in the
third quarter of 2000.




In South America, the company reported revenue of $32 million, compared with
third quarter 2000 revenue of $42 million. Currency depreciation caused $8
million of this decrease.

Revenue from the company's Asian operations grew to $16 million from $15 million
in the third quarter of 2000, primarily due to an increase in original equipment
volumes in China.

Combined EBIT for Australia, South America, and Asia was $5 million, compared
with the previous year EBIT for the quarter of $8 million. Currency fluctuations
and overall lower volumes resulted in lower earnings for these regions.

Tenneco Automotive was awarded 25 new original equipment contracts in the
quarter, building on its strong global book of business. The company's ride
control and emission control products were also featured on 26 new vehicles
launched during the third quarter. Among these launches, Tenneco Automotive
supplied the exhaust system for the Ford Thunderbird, exhaust components on the
Nissan Frontier extended bed pick-up truck, and shock absorbers on the Ford FX4
Off-Road truck. In the aftermarket business, growth was highlighted by
completion of the initial ride control shipment for Sears and its 1,051 retail
outlets in North America.




"We continue to strengthen our aftermarket and original equipment businesses for
the long-term. At the same time, we are making progress in restructuring our
operations and controlling costs," Frissora said. "Despite these positive steps,
we remain cautious about the remainder of the year and 2002 due to the
uncertainty in the automotive markets worldwide."
