LAKE FOREST, ILLINOIS, OCTOBER 25, 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."

The following exhibits provide additional information on Tenneco Automotive's third quarter 2001 operating results.

LAKE FOREST, ILLINOIS, OCTOBER 25, 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:

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."

• 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 25, 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.
