      |      Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR or
      |      portion thereof, will be filed on or before the fifteenth calendar
      |      day following the prescribed due date; or the subject quarterly

PART III -- NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
10-Q, N-SAR or N-CSR, or the transition report or portion thereof, could not be
filed within the prescribed time period.

The company announced on July 23, 2007 that it would restate its financial
statements primarily to correct the accounting for interest rate swaps that the
company entered into in 2004. As previously disclosed, the restatement will also
reflect other accounting adjustments, as well as the results of Tenneco's
reconciliation of its deferred tax balances. The restatement will impact the
years ended December 31, 2004, 2005 and 2006 and the quarters ended March 31,
2006 and 2007, June 30, 2006 and September 30, 2006. The company plans to file
an amendment to its Form 10-K for the year ended December 31, 2006 and an
amendment to its Form 10-Q for the quarter ended March 31, 2007 on August 14,
2007. Because the restated financial statements will not be filed until August
14, the company's Form 10-Q for the second quarter 2007 will not be filed until
that date.



PART IV -- OTHER INFORMATION

     notification:

(2)  Have all other periodic reports required under Section 13 or 15(d) of the
     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
     of 1940 during the preceding 12 months or for such shorter period that the
     registrant was required to file such report(s) been filed? If answer is no,
     identify report(s).                                         [X] Yes  ___ No

(3)  Is it anticipated that any significant change in results of operations from
     the corresponding period for the last fiscal year will be reflected by the
     earnings statements to be included in the subject report or portion
     thereof?
                                                                 ___ Yes  [X] No

     If so, attach an explanation of the anticipated change, both narratively
     and quantitatively, and, if appropriate, state the reasons why a reasonable
     estimate of the results cannot be made.
