TENNECO AUTOMOTIVE CLOSES ON $800 MILLION SENIOR CREDIT FACILITY AND OFFERING
                    OF $125 MILLION OF SENIOR SECURED NOTES
              TRANSACTIONS IMPROVE COMPANY'S FINANCIAL FLEXIBILITY

Lake Forest, Illinois, December 12, 2003 -- Tenneco Automotive (NYSE: TEN)
announced that the company on Friday, December 12 closed on its $800 million
senior credit facility and a private offering of $125 million of 10.25 percent
Senior Secured Notes, due July 15, 2013.

These two transactions completed the refinancing of Tenneco Automotive's senior
credit facility, which the company started in June with the issuance of a $350
million senior secured note.

With the closing of this most recent transaction, the company accomplished the
following:

*        Replaced its current revolver facility with a new source of long-term
         liquidity;
*        Extended most of its debt maturities to 2009 and beyond with a minimal
         pro forma increase to its interest expense; and

                                      -2-


*        Favorably reset its financial covenant ratios through 2010.

The $800 million senior credit facility, which is an amendment and restatement
of the company's prior senior credit facility, includes a 5-year revolving line
of credit of $220 million, a 7-year term loan of $400 million and a 7-year
letter of credit facility of $180 million, which can also be used as a revolving
line of credit to fund short-term borrowings. Loans under the senior facility
will be priced initially at LIBOR plus 3.25%.

"We are very pleased to successfully complete this transaction, which will
improve Tenneco Automotive's financial flexibility by providing a committed
long-term source of liquidity, favorably adjusting our financial covenant ratios
through 2010, and extending nearly all of our debt maturities to 2009 and
beyond," said Mark P. Frissora, chairman and CEO, Tenneco Automotive.

The notes were sold to investors at a premium of 13 percent above the face
value, resulting in net proceeds to the company from the transaction of $136
million after deducting fees and other transaction related expenses. The notes
were issued under the same indenture and have the same terms as the $350 million
of 10.25% senior secured notes due in 2013 that the company issued in June of
this year.

The company used the net proceeds of initial borrowings under the $800 million
senior credit facility and the sale of the notes to repay all amounts previously
outstanding under the company's senior credit facility. Prior to these
transactions, the company's senior credit facility was for $964 million,
consisting of $514 million of term loans maturing in 2005, 2007 and 2008 and a
$450 million revolving line of credit, which was scheduled to terminate in 2005.
The prior term loans had a weighted average interest rate of LIBOR plus 4.05%.

On a pro forma basis, this most transaction would have increased the company's
2002 full year interest expense by only $1 million. However the company is
considering reducing its interest expense by using interest rate swaps to
convert a portion of its fixed rate debt to lower-cost floating rate debt.

registration under the Securities Act of 1933 for an offer and sale of
