LAKE FOREST, ILLINOIS, APRIL 23, 2002 - Tenneco Automotive (NYSE: TEN) announced today that the company's first quarter 2002 performance improved significantly versus one year ago with a reported net loss of $2 million, or 5-cents per share, for the first quarter of 2002, compared with a net loss of $31 million, or 84-cents per share, in the first quarter of 2001. More importantly, the company generated $14 million in positive cash flow, before financing activities, which was a $73 million cash flow improvement versus first quarter 2001. The company also reduced its net debt by $11 million at quarter-end.

"We are pleased with an improved first quarter and particularly with our momentum in North America as well as our continued success in effectively managing cash," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "We continue to make steady progress on our key objectives of improving gross margins, reducing working capital, and operating more efficiently, which is reflected in our improving performance."

The company reported revenue of $809 million for the quarter, down 6 percent versus $864 million in the first quarter of 2001. EBITDA for the quarter was $61 million, compared with $43 million the previous year, a 42 percent improvement. Year-over-year, working capital performance improved by $184 million and capital spending was $2 million lower.

The first quarter 2002 results include a pre-tax non-accruable restructuring expense of $1 million (1-cent per share), pre-tax charges associated with the company's renegotiation of its senior debt agreements of $2 million (3-cents per share) and income from a tax benefit of $4 million (10-cents per share). In addition, the company incurred higher incremental aftermarket changeover costs of $5 million (7-cents per share) in the first quarter of 2002 related to acquiring significant new aftermarket business. The first quarter 2001 results included pre-tax restructuring charges of $12 million (23-cents per share), pre-tax environmental charges of $6 million (12-cents per share) and $2 million in charges associated with the company's renegotiation of its senior debt agreements (5-cents per share).

NORTH AMERICA
"We are encouraged by our North American aftermarket performance and the results we are seeing this quarter from expanding our customer base and leveraging our premium products," Frissora said. "In addition, our lean initiatives and Six Sigma in the North American original equipment business drove improved profitability."

North American original equipment revenue increased 5 percent during the quarter to $341 million versus $324 million in the first quarter of 2001. Excluding catalytic converter pass-through sales, revenue decreased 1 percent. North American aftermarket revenue increased 14 percent to $126 million from $111 million one year ago.

North American EBIT increased to $19 million from a loss of $3 million in the first quarter of 2001. EBIT improvement was driven by stronger aftermarket performance and lower manufacturing and overhead costs. First quarter 2001 EBIT included $8 million in restructuring charges and $1 million in environmental charges.

EUROPE
"In Europe, we continue to face a struggling market for replacement parts and expect to see improvement as we lower our cost of doing business, reduce capacity in the aftermarket exhaust business and fuel growth with new business and product introductions," Frissora said. "We were also impacted this quarter by slowing vehicle sales and launches of key platforms with our components that were delayed until the second quarter."

The company reported European original equipment revenue of $207 million for the quarter, a 25 percent decrease over first quarter 2001 revenue of $275 million. Excluding catalytic converter pass-through sales, revenue would have decreased 14 percent. The 25 percent decrease in the company's European original equipment revenue was the result of lower precious metal prices (10 percent), lower currency exchange rates (5 percent), lower production volumes (9 percent) and delayed platform launches with Tenneco Automotive products (1 percent). The company's European aftermarket revenue decreased 12 percent to $65 million, versus $74 million one year ago.

European EBIT was $5 million, down from $8 million in 2001. The decline this quarter was the result of lower volumes in both the original equipment and aftermarket businesses. First quarter 2001 EBIT included $2 million in restructuring charges, $5 million in environmental charges and $1 million in charges associated with renegotiation of the company's senior debt agreements.

REST OF WORLD
The company's Australian operations reported revenue of $26 million for the quarter, even with the first quarter of 2001.

In South America, the company reported revenue of $26 million, compared with first quarter 2001 revenue of $36 million. The sharp decline was primarily the result of worsening economic conditions in Argentina and currency devaluations in Brazil and Argentina of $7 million.

Revenue from the company's Asian operations was also flat year-over-year at $18 million.

Combined EBIT for Australia, South America, and Asia was $3 million compared with $1 million in first quarter 2001. First quarter 2001 EBIT included $2 million in restructuring charges and $1 million in charges related to renegotiating the company's senior debt agreements.

"While we see some positive upturns in our North American markets, we remain cautiously optimistic given the global nature of our business and our exposure to softer economies and slowing vehicle sales in Europe and South America," Frissora said. "We continue to be a cash-driven organization, focused on the areas we can control and our long-term goal of debt reduction through gross margin improvement."

First quarter 2001 EBIT included $2 million in restructuring charges, $5 million in environmental charges and $1 million in charges associated with renegotiation of the company's senior debt agreements.

REST OF WORLD
The company's Australian operations reported revenue of $26 million for the quarter, even with the first quarter of 2001.

In South America, the company reported revenue of $26 million, compared with first quarter 2001 revenue of $36 million. The sharp decline was primarily the result of worsening economic conditions in Argentina and currency devaluations in Brazil and Argentina of $7 million.

Revenue from the company's Asian operations was also flat year-over-year at $18 million.

Combined EBIT for Australia, South America, and Asia was $3 million compared with $1 million in first quarter 2001. First quarter 2001 EBIT included $2 million in restructuring charges and $1 million in charges related to renegotiating the company's senior debt agreements.

"While we see some positive upturns in our North American markets, we remain cautiously optimistic given the global nature of our business and our exposure to softer economies and slowing vehicle sales in Europe and South America," Frissora said. "We continue to be a cash-driven organization, focused on the areas we can control and our long-term goal of debt reduction through gross margin improvement."

LAKE FOREST, ILLINOIS, APRIL 23, 2002 - Tenneco Automotive (NYSE: TEN) announced today that the company's first quarter 2002 performance improved significantly versus one year ago with a reported net loss of $2 million, or 5-cents per share, for the first quarter of 2002, compared with a net loss of $31 million, or 84-cents per share, in the first quarter of 2001. More importantly, the company generated $14 million in positive cash flow, before financing activities, which was a $73 million cash flow improvement versus first quarter 2001. The company also reduced its net debt by $11 million at quarter-end.

"We are pleased with an improved first quarter and particularly with our momentum in North America as well as our continued success in effectively managing cash," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "We continue to make steady progress on our key objectives of improving gross margins, reducing working capital, and operating more efficiently, which is reflected in our improving performance."

The company reported revenue of $809 million for the quarter, down 6 percent versus $864 million in the first quarter of 2001. EBITDA for the quarter was $61 million, compared with $43 million the previous year, a 42 percent improvement. Year-over-year, working capital performance improved by $184 million and capital spending was $2 million lower.

The first quarter 2002 results include a pre-tax non-accruable restructuring expense of $1 million (1-cent per share), pre-tax charges associated with the company's renegotiation of its senior debt agreements of $2 million (3-cents per share) and income from a tax benefit of $4 million (10-cents per share). In addition, the company incurred higher incremental aftermarket changeover costs of $5 million (7-cents per share) in the first quarter of 2002 related to acquiring significant new aftermarket business. The first quarter 2001 results included pre-tax restructuring charges of $12 million (23-cents per share), pre-tax environmental charges of $6 million (12-cents per share) and $2 million in charges associated with the company's renegotiation of its senior debt agreements (5-cents per share).

NORTH AMERICA
"We are encouraged by our North American aftermarket performance and the results we are seeing this quarter from expanding our customer base and leveraging our premium products," Frissora said. "In addition, our lean initiatives and Six Sigma in the North American original equipment business drove improved profitability."

North American original equipment revenue increased 5 percent during the quarter to $341 million versus $324 million in the first quarter of 2001. Excluding catalytic converter pass-through sales, revenue decreased 1 percent. North American aftermarket revenue increased 14 percent to $126 million from $111 million one year ago.

North American EBIT increased to $19 million from a loss of $3 million in the first quarter of 2001. EBIT improvement was driven by stronger aftermarket performance and lower manufacturing and overhead costs. First quarter 2001 EBIT included $8 million in restructuring charges and $1 million in environmental charges.

EUROPE
"In Europe, we continue to face a struggling market for replacement parts and expect to see improvement as we lower our cost of doing business, reduce capacity in the aftermarket exhaust business and fuel growth with new business and product introductions," Frissora said. "We were also impacted this quarter by slowing vehicle sales and launches of key platforms with our components that were delayed until the second quarter."

The company reported European original equipment revenue of $207 million for the quarter, a 25 percent decrease over first quarter 2001 revenue of $275 million. Excluding catalytic converter pass-through sales, revenue would have decreased 14 percent. The 25 percent decrease in the company's European original equipment revenue was the result of lower precious metal prices (10 percent), lower currency exchange rates (5 percent), lower production volumes (9 percent) and delayed platform launches with Tenneco Automotive products (1 percent). The company's European aftermarket revenue decreased 12 percent to $65 million, versus $74 million one year ago.

European EBIT was $5 million, down from $8 million in 2001. The decline this quarter was the result of lower volumes in both the original equipment and aftermarket businesses. First quarter 2001 EBIT included $2 million in restructuring charges, $5 million in environmental charges and $1 million in charges associated with renegotiation of the company's senior debt agreements.

REST OF WORLD
The company's Australian operations reported revenue of $26 million for the quarter, even with the first quarter of 2001.

In South America, the company reported revenue of $26 million, compared with first quarter 2001 revenue of $36 million. The sharp decline was primarily the result of worsening economic conditions in Argentina and currency devaluations in Brazil and Argentina of $7 million.

Revenue from the company's Asian operations was also flat year-over-year at $18 million.

Combined EBIT for Australia, South America, and Asia was $3 million compared with $1 million in first quarter 2001. First quarter 2001 EBIT included $2 million in restructuring charges and $1 million in charges related to renegotiating the company's senior debt agreements.

"While we see some positive upturns in our North American markets, we remain cautiously optimistic given the global nature of our business and our exposure to softer economies and slowing vehicle sales in Europe and South America," Frissora said. "We continue to be a cash-driven organization, focused on the areas we can control and our long-term goal of debt reduction through gross margin improvement."
