LAKE FOREST, ILLINOIS, JANUARY 31, 2005 - Tenneco Automotive (NYSE: TEN) announced today that the company will make a voluntary $40 million cash pre-payment on its $396 million Term Loan B credit facility, which matures in December 2010.

"We remain committed to our number one priority of generating cash to pay down debt," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "Our sharp focus on business growth, cost reduction and operational improvement over the last five years has increased earnings and improved working capital, both strategies for generating cash for debt reduction."
