         TENNECO AUTOMOTIVE REPORTS HIGHER EARNINGS AND SUBSTANTIAL DEBT
                        REDUCTION IN SECOND QUARTER 2002

- -    Reports EPS of 45-cents for 2Q 2002 versus 6-cents for 2Q 2001
- -    Reduces total debt $86 million on stronger cash flow
- -    Improves working capital, before factoring, by $171 million year-over-year
- -    Increases North American profitability 76 percent
- -    Wins $127 million in new business globally


LAKE FOREST, ILLINOIS, JULY 23, 2002 - Tenneco Automotive (NYSE: TEN) today
announced that the company continues to improve performance with reported net
income of $19 million, or 45-cents per diluted share, for the second quarter
2002 compared with net income of $2 million, or 6-cents per diluted share during
the second quarter 2001. The company generated $89 million in positive cash flow
before financing activities during the quarter, a $72 million cash flow
improvement versus second quarter 2001. This strong cash performance allowed the
company to decrease its total debt by $86 million during the quarter and by $94
million year to date. Global original equipment customers awarded Tenneco
Automotive $127 million in new business through 2005 during the quarter.

                                      -2-

The second quarter 2002 results include a one-time pre-tax benefit of $11
million, or 13-cents per diluted share, for the sale of the company's previously
closed York, U.K. facility and a pre-tax non-accruable restructuring expense of
$2 million, or 2-cents per diluted share. The second quarter 2001 results
include pre-tax restructuring costs of $10 million, or 20-cents per diluted
share.

"We are making solid progress on improving our operating fundamentals as well as
in the important area of cash management. Our cash performance this quarter was
outstanding, which helps us address our top financial objective of lowering the
debt load since becoming an independent company," said Mark P. Frissora,
chairman and CEO, Tenneco Automotive. "Our North American businesses led the way
this quarter, driven by increased volumes, a strengthening aftermarket ride
control mix and improved manufacturing efficiency."

The company reported revenue for the quarter of $948 million, compared with $925
million in the second quarter of 2001, a 2 percent increase. Reported EBITDA for
the quarter was $106 million, compared with $86 million the previous year.

Working capital in the second quarter, before factoring, improved $171 million
year-over-year, or as a percent of sales, from 13.3 percent to 8.8 percent.
Through the first six months of 2002, the company generated $59 million in cash
flow from working capital, exceeding its 2002 goal of $50 million. Adjusted for
restructuring costs, the company recorded gross margin of 21.8 percent in the
second quarter 2002, unchanged from the same period one year ago. Through the
first six months of 2002, the company has improved its gross margin, adjusted
for restructuring costs, by nearly one percentage point. The company's SGA&E, as
a percent of sales, in the second quarter was also unchanged year-over-year at

11.6 percent. Excluding restructuring costs, SGA&E was relatively flat through
the first half of 2002 as well. The company outperformed its bank covenant test
ratios in the second quarter by an even larger margin than it achieved in the
first quarter of 2002.

"Our financial results were impacted this quarter by lower original equipment
and aftermarket volumes in Europe," said Frissora. "We are taking aggressive
steps to align our operations and cost structure with changing market
conditions. We are focused on putting the right engineering and manufacturing
processes in place to improve efficiency and flexibility throughout our
operations in order to help counter soft industry conditions in Europe."

NORTH AMERICA

North American original equipment (OE) revenue increased 12 percent during the
quarter to $391 million versus $350 million in the second quarter of 2001.
Excluding catalytic converter pass-through sales, revenue increased 9 percent.
North American aftermarket revenue increased four percent to $148 million from
$143 million one year ago.

North American EBIT increased to $53 million from $20 million in the second
quarter of 2001. Stronger OE volumes, an increasing premium aftermarket ride
control mix, aftermarket pricing increases and significantly improved
manufacturing through lean initiatives helped drive this performance. North
American EBIT results include approximately $1 million in incremental new
customer changeover costs year-over-year and $1 million in restructuring costs.
North American EBIT in second quarter 2001 included $10 million in restructuring
costs. Excluding restructuring costs, the company's North American profitability
improved 76 percent year-over-year.

EUROPE

The company reported European original equipment revenue of $231 million for the
quarter, an 11 percent decrease compared with second quarter 2001 revenue of
$259 million. The favorable impact on sales of stronger currency was fully
offset by lower precious metal prices in the company's catalytic converter
pass-through sales. The company's European aftermarket revenue increased to $90
million, versus $88 million one year ago. Excluding the impact of currency,
aftermarket sales were down 6 percent year-over-year, primarily due to the
impact of longer-lasting stainless steel OE exhaust products.

European EBIT was $11 million for the quarter, compared with $22 million
reported in the second quarter of 2001. Lower OE and aftermarket volumes, OE
launch delays and costly start-up issues on some exhaust platforms impacted
European profitability. Results include an $11 million gain from the sale of a
previously closed U.K. facility, a $1 million increase in reserves for recently
identified warranty issues and $1 million in restructuring costs.

REST OF WORLD

The company's operations in Australia, Asia and South America improved
profitability on essentially flat year-over-year revenues. The Australian
operations reported revenue of $31 million for the quarter, compared with $27
million in the second quarter of 2001. In South America, the company reported
revenue of $28 million, compared with $37 million one year ago. Revenue from the
company's Asian operations was $29 million, versus $21 million in the second
quarter of 2001.

Combined EBIT for Australia, South America and Asia was $7 million compared with
$5 million one year ago. Tighter cost management and improved operational
performance in South America, coupled

with stronger OE demand in Australia more than offset the impact of a two-week
strike at our Australian OE exhaust plant and worsening economic conditions in
Brazil and Argentina.
