ITEM 5.04 TEMPORARY SUSPENSION OF TRADING UNDER REGISTRANT'S EMPLOYEE BENEFIT
          PLANS

         On February 9, 2006, Tenneco Inc. sent a notice to participants in the
Tenneco Employee Stock Ownership Plan for Salaried Employees and the Tenneco
Employee Stock Ownership Plan for Hourly Employees (collectively, the "401(k)
plans") informing them that, due to a change in record keepers and changes in
available investment options under the 401(k) plans, a blackout period under the
401(k) plans would be in effect beginning at 3:00 p.m. eastern time on March 20,
2006 until 9:30 a.m. eastern time on April 3, 2006. The notice stated that,
during the blackout period, participants in the 401(k) plans will not be able to
transfer or reallocate funds, change contribution rates, make new investment
elections or request loans, withdrawals or final distributions from the 401(k)
plans.

         On February 13, 2006, Tenneco Inc. also sent a notice (the "BTR
Notice") to its executive officers and directors informing them that, pursuant
to Section 306(a) of the Sarbanes-Oxley Act of 2002 and the SEC's rules
promulgated thereunder, they would be prohibited from purchasing and selling
shares of Tenneco's common stock (including derivative securities pertaining to
such shares) on the open market or otherwise during the blackout period. A copy
of the BTR Notice is attached hereto as Exhibit 99.1 and is incorporated herein
by reference. Tenneco provided the BTR Notice to its executive officers and
directors within five business days of February 9, 2006, which is the date that
notices were mailed to participants in the 401(k) plans and Tenneco was notified
of the blackout period.
