       TENNECO ACQUIRES MOBILE EMISSIONS BUSINESS OF COMBUSTION COMPONENTS
                                ASSOCIATES, INC.
   COMPANY ADVANCES ITS FULL-SYSTEM SCR EMISSIONS CAPABILITIES TO MEET FUTURE
                               DIESEL REGULATIONS

Lake Forest, Illinois, August 20, 2007 -- Tenneco Inc. (NYSE: TEN) today
announced that it has signed an agreement to acquire the mobile emissions
business of Combustion Components Associates, Inc. (CCA), a manufacturer of air
pollution control technologies. The acquisition enhances Tenneco's complete
system integration capabilities for selective catalyst reduction (SCR) emissions
control technologies designed to meet future more stringent diesel emissions
regulations for passenger cars and trucks.

CCA develops emissions control solutions for customers in the transportation and
power generation industries. The company has designed and manufactured a
Nitrogen Oxides (NOx) emission reduction system called ELIM-NOx(TM), which is
designed to reduce NOx emissions by 70 to 90 percent using SCR technology. SCR
is the process of removing NOx through a chemical reaction and is considered the
leading technology for helping diesel engines meet the NOx emissions standards.
Customer demands for this new technology, driven by regulations, will increase
in the U.S., Europe and China starting in 2010 -- 2012.

"This acquisition strengthens our advanced technology offering. ELIM-NOx(TM) is
one of the few proven high-performance systems for urea and hydrocarbon
injection. Combined with the SCR technology we produce today, Tenneco can offer
our customers a fully-integrated emission control system to meet stringent
diesel emissions regulations for NOx reduction," said Gregg Sherrill, Tenneco
Chairman and CEO. "This technology allows us to optimize both the performance
and cost of a total aftertreatment system, providing greater value for our
customers globally."

The ELIM-NOx(TM) injector system and "self-learn" monitoring device are unique.
The injector system is capable of providing rapid, uniform dispersion of urea
without the use of steam or compressed air, reducing overall system lifecycle
cost. Tenneco believes that, with this technology, it will be the only complete
emissions control system manufacturer with the capability to manufacture and
integrate its own injector systems into a diesel emissions control system.

The "self-learn" monitoring device--which uses sensors to measure NOx, exhaust
temperature, and other engine parameters-- significantly reduces vehicle
development time and cost. It is temporarily mounted on a development vehicle as
it operates in normal driving conditions. This helps minimize off-line vehicle
testing and calibration.

"The CCA self-learning capability is truly unique, allowing for very quick
prototyping of development vehicles. We believe it will offer an extremely
attractive system integration alternative for our customers, saving both time
and

                                     -More-



money compared to traditional dynamometer calibration techniques," said Tim
Jackson, Tenneco Chief Technology Officer.

In addition to providing this innovative solution to original equipment
manufacturers, Tenneco will also sell retrofit versions of the ELIM-NOx(TM)
system for commercial vehicles. Later this year, the company expects to complete
final validation testing for the system to be added to the EPA list of verified
retrofit technologies.

Tenneco will purchase CCA's mobile emission business for approximately $16
million. The transaction is subject to customary closing conditions, including
receipt of various third party approvals. Tenneco expects the transaction to
close in September.
