           TENNECO AUTOMOTIVE TO REDUCE WORLDWIDE SALARIED WORK FORCE


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
