               TENNECO ANNOUNCES INTENTION TO CLOSE ITS WISSEMBOURG, FRANCE
                                 MANUFACTURING FACILITY

          Lake Forest, Illinois, September 20, 2007 -- Tenneco Inc. (NYSE: TEN)
          announced today its intention to close its Wissembourg, France
          manufacturing facility, which produces emission control products for
          original equipment manufacturers. The company will consult with work
          councils and local government authorities on the intended closure and
          potential impact of this announcement on the approximately 180 people
          employed at the facility.

          Tenneco continues to look for opportunities to improve operating
          efficiency and optimize its global manufacturing footprint by matching
          production capacity to customer demand. The intended closure of the
          Wissembourg facility is designed to reduce production overcapacity in
          the region.

          The company will implement any potential workforce reductions that may
          occur as a result of this plan in compliance with all applicable legal
          and contractual requirements including consulting with work councils
          and other employee representatives.

          The potential closure is dependent on discussions with employee work
          councils and, if completed, Tenneco expects it would take up to a $17
          million restructuring charge, beginning as early as the fourth quarter
          2007 and through 2008.

          Tenneco is a $4.7 billion manufacturing company with headquarters in
          Lake Forest, Illinois and approximately 19,000 employees worldwide.
          Tenneco is one of the world's largest designers, manufacturers and
          marketers of emission control and ride control products and systems
          for the automotive original equipment market and the aftermarket.
          Tenneco markets its products principally under the Monroe(R),
          Walker(R), Gillet(TM) and Clevite(R)Elastomer brand names.
