LAKE FOREST, ILLINOIS, JANUARY 31, 2001 - Tenneco Automotive (NYSE: TEN) announced today that it intends to eliminate up to an additional 405 salaried positions worldwide in response to increasingly difficult industry conditions. This reduction includes the immediate elimination of 215 positions.

This action is in addition to the cost-reduction plans announced by the company in October 2000 that included eliminating up to 700 salaried positions worldwide by the end of 2001. Today's cost-reduction plans are expected to be fully implemented by the end of the first quarter 2002, at which time the company anticipates it will have reduced its worldwide salaried workforce by 22 percent as a result of the two initiatives.

Like many others in the automotive supply sector, the company continues to be negatively impacted by a persistent weakness in the global aftermarket, cutbacks in North American light vehicle production, and a sharp decline in North American heavy-duty truck production.

"We regret the impact on our people as we eliminate more positions," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "However, we are facing very tough industry conditions which, coupled with our highly leveraged structure, make it absolutely necessary to respond as quickly as possible by continuing to aggressively cut costs and reduce spending".

Tenneco Automotive estimates that this cost reduction plan will generate approximately $27 million in annual savings when fully implemented. The company anticipates taking cash charges of up to $14 million in 2001 related to the reductions announced today. All work force reductions will be done in compliance with all legal and contractual requirements including obligations to consult with worker committees, union representatives and others.

The annual savings are expected to be in addition to the approximately $45 million in annual savings the company anticipates it will realize when the workforce reduction plans announced in October 2000 are completed at the end of 2001.

Tenneco Automotive is a $3.5 billion manufacturing company headquartered in Lake Forest, Ill., with 23,000 employees worldwide. Tenneco Automotive is one of the world's largest producers and marketers of ride control and exhaust systems and products, which are sold under the Monroe® and Walker ® global brand names. Among its products are Sensa-Trac® and Reflex shocks and struts, Rancho® shock absorbers, Walker® Quiet-Flow® mufflers and DynoMax® performance exhaust products, and Monroe® Clevite™ vibration control components.
