                  TENNECO REPORTS SOLID SECOND QUARTER RESULTS

   -     GLOBAL AFTERMARKET REVENUE INCREASES 7%

   -     EUROPEAN SEGMENT EBIT UP 34%

   -     GROSS MARGIN IMPROVES TO 20.5%

Lake Forest, Illinois, July 27, 2006 - Tenneco Inc. (NYSE: TEN) reported second
quarter 2006 net income of $24 million, or 53-cents per diluted share, versus
$33 million, or 71-cents per diluted share one year ago. Adjusted for the items
below, net income was $33 million, or 73-cents per diluted share, compared with
$35 million, or 77-cents per diluted share in second quarter 2005 (see the
attached tables, which reconcile GAAP results to non-GAAP results).

EBIT (earnings before interest, taxes and minority interest) was $73 million,
versus $83 million in second quarter 2005. On an adjusted basis, EBIT was $87
million, versus $85 million a year ago. EBITDA (EBIT before depreciation and
amortization) was $120 million, compared with $127 million the previous year.
Adjusted EBITDA was $134 million, compared with second quarter 2005 adjusted
EBITDA of $129 million.

Although adjusted EBIT and EBITDA were up year-over-year, adjusted net income
declined with the impact of higher interest costs on the company's variable rate
debt and increased minority interest expense due to growth in the company's
China joint ventures.

Tenneco said its strong geographic and market balance, and diverse customer base
helped the company produce solid results in light of challenging original
equipment market conditions in North America and Australia. The company's
European segment, the global aftermarket and China operations delivered improved
revenue and earnings performance, partially offsetting the impact of lower OE
volumes in North America and higher material costs globally. The company was
also aided in the quarter by ongoing efforts to improve operational efficiency
through Lean manufacturing and Six Sigma programs, and tight control of
discretionary spending.

SECOND QUARTER 2006 ADJUSTMENTS:

      -     Restructuring and restructuring related expenses of $8 million
            pre-tax, or 12-cents per diluted share;

      -     Aftermarket customer changeover costs of $6 million pre-tax, or
            8-cents per diluted share.

SECOND QUARTER 2005 ADJUSTMENTS:

      -     Restructuring and restructuring related expenses of $2 million
            pre-tax, or 3-cents per diluted share;

      -     Tax expense of $1 million, or 3-cents per diluted share, primarily
            related to adjusting state tax net operating loss carry forwards.

Tenneco reported second quarter revenue of $1.22 billion, up from $1.18 billion
a year ago. Favorable currency benefited revenue by $19 million. Excluding the
impact of currency and substrate sales, revenue was down about 1%.

Cash flow generated from operations in the quarter was $80 million, compared
with $32 million in second quarter 2005 when the discontinuation of the General
Motors Advanced Payment Program negatively impacted cash performance. This
improved cash performance has allowed the company to make additional capital
investments for significant growth expected in 2007.

Debt net of cash was $1.246 billion, down from $1.346 billion a year ago. The
ratio of debt net of cash balances to adjusted LTM (Last Twelve Months) EBITDA
was 3.0, versus 3.3 for the same period last year. At quarter-end, total debt
decreased to $1.369 billion from $1.412 billion a year ago.

Tenneco's gross margin in the quarter was 20.5%, an improvement over 20.3% a
year ago. Operational improvements and the impact of higher margin North
American aftermarket ride control sales more than offset higher restructuring
costs; the impact of increased European substrate sales on high volume
platforms; and $8 million related to higher gross material costs.

Sales, General, Administrative and Engineering (SGA&E) expense in the quarter
was 10.6% of sales versus 9.4% in second quarter 2005. SGA&E expense for the
quarter as a percentage of LTM sales was 10.8%, an improvement from 11.1% for
the same period a year ago. SGA&E in the quarter was impacted by restructuring
and aftermarket customer changeover costs.



                                       -3-

NORTH AMERICA

      -     North America OE revenue was $367 million, down from revenue of $390
            million a year ago. Excluding the impact of currency, revenue was
            $365 million (the attached tables reconcile GAAP revenues to
            revenues adjusted for substrate sales and currency.) The decrease
            was primarily the result of lower exhaust volumes due to OE
            production declines and the build out on several key exhaust
            platforms, which more than offset stronger heavy duty ride control
            volumes and the ramp-up of a major ride control platform.

      -     North America aftermarket revenue increased 8% to $157 million,
            versus $146 million a year ago. The increase was driven by higher
            ride control volumes and price increases in both the ride control
            and exhaust product lines. Business from previously announced new
            customers generated $3 million of the revenue increase.

      -     EBIT for North American operations was $37 million, compared with
            $52 million in second quarter 2005. Second quarter 2006 EBIT
            includes $4 million in restructuring costs and $6 million for
            aftermarket customer changeover costs.

      -     In addition to the negative impact of restructuring and aftermarket
            customer changeover costs, EBIT was impacted by lower OE exhaust
            volumes and higher material costs, which more than offset
            manufacturing efficiency improvements and cost reduction efforts.

EUROPE, SOUTH AMERICA AND INDIA

      -     Europe OE revenue was $412 million, up from $382 million a year ago.
            Excluding the impact of currency, revenue was up almost 5%.
            Substrate sales as a percentage of revenue increased to 37% of total
            Europe OE emission control revenue from 31% a year ago due to an
            increase in diesel aftertreatment and hot-end exhaust business.

      -     Europe aftermarket revenue was $118 million, up 9% from $109 million
            in second quarter 2005 and up 7% excluding the impact of currency.
            The increase was driven by stronger ride control volumes and price
            increases and market share gains in the exhaust business.

      -     South America and India revenue was $66 million, up from $59 million
            the previous year. Higher volumes in South America and India and a
            $4 million positive currency impact in South America drove the
            increase.

      -     EBIT for Europe, South America and India was $34 million, a 34%
            increase over $27 million a year ago. EBIT benefited from $1 million
            in currency.

      -     EBIT included $3 million in restructuring costs compared with $2
            million in second quarter 2005.

      -     The significant EBIT improvement, despite a higher percentage of
            substrate sales, was primarily driven by better manufacturing
            performance, particularly in the European OE emission control
            business; higher aftermarket sales; and tight spending controls.

ASIA PACIFIC

      -     Asia revenue was $58 million, a 60% increase over $35 million a year
            ago, mainly driven by higher OE exhaust sales in China including new
            platform launches. Excluding substrate sales, revenue was up 51%
            year-over-year.

      -     Australia revenue was $44 million, down 26% from $59 million in
            second quarter 2005, primarily driven by a sharp decline in OE
            volumes with domestic industry production down almost 25% compared
            with the previous year. Lower aftermarket sales also negatively
            impacted revenue.

      -     Asia Pacific EBIT was $2 million, versus $4 million a year ago.
            Second quarter 2006 EBIT included $1 million in restructuring costs.



                                       -4-

      -     The EBIT decline was the result of lower OE volumes in Australia and
            higher workers compensation costs in Australia, which more than
            offset operational improvements in Asia OE operations and the
            benefit from new business launches in China.

YEAR-TO-DATE RESULTS

Like other auto suppliers, Tenneco has faced a difficult environment through the
first half of 2006. The company's strong global manufacturing and distribution
footprint; presence in a variety of markets; and diverse customer base have
helped mitigate market pressures, particularly in North America and Australia.
In addition, the company has benefited from its focus on consistent strategies
for improving cash performance, optimizing operations, and controlling costs,
while preparing for a significant growth year in 2007.

Through the first half of 2006, Tenneco reported net income of $31 million, or
67-cents per diluted share, versus net income of $40 million, or 88-cents per
diluted share for the first six months of 2005. On an adjusted basis,
year-to-date net income was $42 million, or 94-cents per diluted share, compared
with $44 million, or 97-cents per diluted share a year ago.

Year-to-date EBIT was $115 million compared with EBIT of $127 million for the
first half of 2005. Adjusted year-to-date EBIT was $136 million compared with
$132 million the previous year. EBITDA was $206 million, versus $217 million a
year ago. Adjusted EBITDA was $227 million for the first half of 2006, versus
$222 million for the same period a year ago.

OUTLOOK

Tenneco anticipates that the North American and Australian OE markets will
continue to be challenging with revenue and earnings pressure from lower OE
production rates through the remainder of the year. The company hopes to counter
the impact of market downturns with its European segment and China operations.
The company also intends to stay focused on factors within its control -
intensely managing costs; continuously improving manufacturing efficiency; and
leveraging global supply chain spending.

Tenneco remains committed to its goal of de-leveraging by reducing net debt to
adjusted EBITDA to 2.8X by the end of the year.

This press release contains forward-looking statements. Words such as "hopes,"
"estimates," "continue," "will," "plans," "outlook" and "goal" and similar
expressions identify forward-looking statements. These forward-looking
statements are based on the current expectations of the company (including its
subsidiaries). Because these forward-looking statements involve risks and
uncertainties, the company's plans, actions and actual results could differ
materially. Among the factors that could cause these plans, actions and results
to differ materially from current expectations are:

(i) changes in automotive manufacturers' production rates and their actual and
forecasted requirements for the company's products;

(ii) the overall highly competitive nature of the automotive parts industry,
including pricing pressure from the company's OE customers and the loss of any
awards of business, or the failure to obtain new awards of business, from our
large customers, on which we are dependent for a substantial portion of our
revenues; for example, Ford, from whom the company derived 12% of its 2005 net
sales, recently announced a plan to significantly reduce the number of its
global suppliers. While the company currently believes that its relationship
with Ford will not be impacted by this plan, any significant reduction in sales
to Ford could have a material adverse effect on the company;

(iii) the company's resultant inability to realize the
sales represented by its awarded book of business which is based on anticipated
pricing for the applicable program over its life, and is subject to increases or
decreases due to changes in customer requirements, customer and consumer
preferences, and the number of vehicles actually produced by customers;

(iv) increases in the costs of raw materials, including the company's ability to
successfully reduce the impact of any such cost increases through materials
substitutions, cost reduction initiatives, customer recovery and other methods;

(v) the cyclical nature of the global vehicular industry, including the
performance of the global aftermarket sector, and changes in consumer demand and
prices, including longer product lives of automobile parts and the cyclicality
of automotive production and sales of automobiles which include the company's
products, and the potential negative impact on the company's revenues and
margins from such products;

(vi) the company's continued success in cost reduction and cash management
programs and its ability to execute restructuring and other cost reduction plans
and to realize anticipated benefits from these plans;



                                       -6-

(vii) the general political, economic and competitive conditions in markets and
countries where the company and its subsidiaries operate, including the strength
of other currencies relative to the U.S. dollar and currency fluctuations and
other risks associated with operating in foreign countries;

(viii) governmental actions, including the ability to receive regulatory
approvals and the timing of such approvals;

(ix) changes in capital availability or costs, including increases in the
company's costs of borrowing (i.e., interest rate increases), the amount of the
company's debt, the ability of the company to access capital markets and the
credit ratings of the company's debt;

(x) the cost and outcome of existing and any future legal proceedings, and
compliance with changes in regulations, including environmental regulations;

(xi) workforce factors such as strikes or labor interruptions;

(xii) the company's ability to develop and profitably commercialize new products
and technologies, and the acceptance of such new products and technologies by
the company's customers and the market;

(xiii) further changes in the distribution channels for the company's
aftermarket products, further consolidations among automotive parts customers
and suppliers, and product warranty costs;

(xiv) changes by the Financial Accounting Standards Board or other accounting
regulatory bodies to authoritative generally accepted accounting principles or
policies;

(xv) acts of war, riots or terrorism, including, but not limited to the events
taking place in the Middle East, the current military action in Iraq and the
continuing war on terrorism, as well as actions taken or to be taken by the
United States or other governments as a result of further acts or threats of
terrorism, and the impact of these acts on economic, financial and social
conditions in the countries where the company operates; and

(xvi) the timing and occurrence (or non-occurrence) of transactions and events
which may be subject to circumstances beyond the control of the company and its
subsidiaries. The company undertakes no obligation to update any forward-looking
statement to reflect events or circumstances after the date of this press
release. Additional information regarding these risk factors and uncertainties
is detailed from time to time in the company's SEC filings, including but not
limited to its report on Form 10-K for the year ended December 31, 2005. Further

(1) Generally Accepted Accounting Principles

(2)EBITDA represents income before interest expense, income taxes, minority
interest and depreciation and amortization. EBITDA is not a calculation based
upon generally accepted accounting principles. The amounts included in the
EBITDA calculation, however, are derived from amounts included in the historical
statements of income data. In addition, EBITDA should not be considered as an
alternative to net income or operating income as an indicator of the company's
operating performance, or as an alternative to operating cash flows as a measure
of liquidity. Tenneco has presented EBITDA because it regularly reviews EBITDA
as a measure of the company's performance. In addition, Tenneco believes its
debt holders utilize and analyze our EBITDA for similar purposes. Tenneco also
believes EBITDA assists investors in comparing a company's performance on a
consistent basis without regard to depreciation and amortization, which can vary
significantly depending upon many factors. However, the EBITDA measure presented
may not always be comparable to similarly titled measures reported by other
companies due to differences in the components of the calculation.

(1) Generally Accepted Accounting Principles

(2) Tenneco presents the above reconciliation of GAAP to non-GAAP earnings
measures primarily to reflect the results for the second quarters of 2006 and
2005 in a manner that allows a better understanding of the results of
operational activities separate from the financial impact of decisions made for
the long-term benefit of the company. Adjustments similar to the ones reflected
above have been recorded in earlier periods, and similar types of adjustments
can reasonably be expected to be recorded in future periods. Using only the
non-GAAP earnings measures to analyze earnings would have material limitations
because its calculation is based on the subjective determinations of management
regarding the nature and classification of events and circumstances that
investors may find material. Management compensates for these limitations by
utilizing both GAAP and non-GAAP earnings measures reflected above to understand
and analyze the results of the business. The company believes investors find the
non-GAAP information helpful in understanding the ongoing performance of
operations separate from items that may have a disproportionate positive or
negative impact on the company's financial results in any particular period.

(3)EBITDA represents income before interest expense, income taxes, minority
interest and depreciation and amortization. EBITDA is not a calculation based
upon generally accepted accounting principles. The amounts included in the
EBITDA calculation, however, are derived from amounts included in the historical
statements of income data. In addition, EBITDA should not be considered as an
alternative to net income or operating income as an indicator of the company's
operating performance, or as an alternative to operating cash flows as a measure
of liquidity. Tenneco has presented EBITDA because it regularly reviews EBITDA
as a measure of the company's performance. In addition, Tenneco believes its
debt holders utilize and analyze our EBITDA for similar purposes. Tenneco also
believes EBITDA assists investors in comparing a company's performance on a
consistent basis without regard to depreciation and amortization, which can vary
significantly depending upon many factors. However, the EBITDA measure presented
may not always be comparable to similarly titled measures reported by other
companies due to differences in the components of the calculation.

(4) Represents costs associated with changing new aftermarket customers from
their prior suppliers to an inventory of our products. Although our aftermarket
business regularly incurs changeover costs, we specifically identify in the
table above the changeover costs that, based on the size or number of customers
involved, we believe are of an unusual nature for the quarter in which they were
incurred.

(1) Generally Accepted Accounting Principles

(2) Tenneco presents the above reconciliation of GAAP to non-GAAP earnings
measures primarily to reflect the results for the first six months of 2006 and
2005 in a manner that allows a better understanding of the results of
operational activities separate from the financial impact of decisions made for
the long-term benefit of the company. Adjustments similar to the ones reflected
above have been recorded in earlier periods, and similar types of adjustments
can reasonably be expected to be recorded in future periods. Using only the
non-GAAP earnings measures to analyze earnings would have material limitations
because its calculation is based on the subjective determinations of management
regarding the nature and classification of events and circumstances that
investors may find material. Management compensates for these limitations by
utilizing both GAAP and non-GAAP earnings measures reflected above to understand
and analyze the results of the business. The company believes investors find the
non-GAAP information helpful in understanding the ongoing performance of
operations separate from items that may have a disproportionate positive or
negative impact on the company's financial results in any particular period.

In addition, 2006 includes adjustments to eliminate the additional stock based
compensation expense and the impact on the diluted shares calculation associated
with FAS 123R, which the company adopted in 2006. The company plans to continue
making this adjustment for the remainder of 2006 to enhance investors'
understanding of the comparability between 2006 and 2005 results. See also
Attachment I, Statements of Income footnote (b for the six months ended June 30.

(3)EBITDA represents income before interest expense, income taxes, minority
interest and depreciation and amortization. EBITDA is not a calculation based
upon generally accepted accounting principles. The amounts included in the
EBITDA calculation, however, are derived from amounts included in the historical
statements of income data. In addition, EBITDA should not be considered as an
alternative to net income or operating income as an indicator of the company's
operating performance, or as an alternative to operating cash flows as a measure
of liquidity. Tenneco has presented EBITDA because it regularly reviews EBITDA
as a measure of the company's performance. In addition, Tenneco believes its
debt holders utilize and analyze our EBITDA for similar purposes. Tenneco also
believes EBITDA assists investors in comparing a company's performance on a
consistent basis without regard to depreciation and amortization, which can vary
significantly depending upon many factors. However, the EBITDA measure presented
may not always be comparable to similarly titled measures reported by other
companies due to differences in the components of the calculation.

(4) Represents costs associated with changing new aftermarket customers from
their prior suppliers to an inventory of our products. Although our aftermarket
business regularly incurs changeover costs, we specifically identify in the
table above the changeover costs that, based on the size or number of customers
involved, we believe are of an unusual nature for the time period in which they
were incurred.

Tenneco presents the above reconciliation of revenues in order to reflect the
trend in the company's sales, in various product lines and geographical regions,
separately from the effects of doing business in currencies other than the U.S.
dollar. Additionally, substrate sales which the company previously referred to
as pass-through sales include precious metals pricing, which may be volatile.
Substrate sales occur when, at the direction of its OE customers, Tenneco
purchases catalytic converters or components thereof from suppliers, uses them
in its manufacturing processes and sells them as part of the completed system.
While Tenneco original equipment customers assume the risk of this volatility,
it impacts reported revenue. Excluding substrate sales removes this impact.
Tenneco uses this information to analyze the trend in revenues before these
factors. Tenneco believes investors find this information useful in
understanding period to period comparisons in the company's revenues.

(a) Beginning in the second quarter of 2005, Tenneco changed its accounting for
a customer contract in its European OE Ride Control unit. The cost of sales for
this contract are now netted against the revenues, reducing reported revenues
and cost of sales. In the first quarter of 2005, Tenneco recorded $15 million in
revenues for this contract.

(1)Tenneco presents debt net of cash balances because management believes it is
a useful measure of Tenneco's credit position and progress toward reducing
leverage. The calculation is limited in that the company may not always be able
to use cash to repay debt on a dollar-for- dollar basis.

(2)Tenneco presents the above reconciliation of the ratio debt net of cash to
the last twelve months (LTM) of adjusted EBITDA to show trends that investors
may find useful in understanding the company's ability to service its debt. For
purposes of this calculation, adjusted LTM EBITDA is used as an indicator of the
company's performance over the most recent twelve months and debt net of cash is
presented as an indicator of our credit position and progress toward reducing
our financial leverage. LTM adjusted EBITDA is used to reflect annual values and
remove seasonal fluctuations. This reconciliation is provided as supplemental
information and not intended to replace the company's existing covenant ratios
or any other financial measures that investors may find useful in describing the
company's financial position. See notes (1), (3) and (4) for a description of
the limitations of using debt net of cash, EBITDA and adjusted EBITDA.

(3)EBITDA represents income before interest expense, income taxes, minority
interest and depreciation and amortization. EBITDA is not a calculation based
upon generally accepted accounting principles. The amounts included in the
EBITDA calculation, however, are derived from amounts included in the historical
statements of income data. In addition, EBITDA should not be considered as an
alternative to net income or operating income as an indicator of the company's
operating performance, or as an alternative to operating cash flows as a measure
of liquidity. Tenneco Inc. has presented EBITDA because it regularly reviews
EBITDA as a measure of the company's performance. In addition, Tenneco believes
its debt holders utilize and analyze our EBITDA for similar purposes. Tenneco
also believes EBITDA assists investors in comparing a company's performance on a
consistent basis without regard to depreciation and amortization, which can vary
significantly depending upon many factors. However, the EBITDA measure presented
may not always be comparable to similarly titled measures reported by other
companies due to differences in the components of the calculation.

(4)Adjusted EBITDA is presented in order to reflect the results in a manner that
allows a better understanding of operational activities separate from the
financial impact of decisions made for the long term benefit of the company and
other items impacting comparability between the periods. Adjustments similar to
the ones reflected above have been recorded in earlier periods, and similar
types of adjustments can reasonably be expected to be recorded in future
periods. The company believes investors find the non-GAAP information helpful in
understanding the ongoing performance of operations separate from items that may
have a disproportionate positive or negative impact on the company's financial
results in any particular period. In addition, 2006 includes adjustments to
eliminate the additional stock based compensation expense and the impact on the
diluted shares calculation associated with FAS 123R, which the company adopted
in 2006. The company plans to continue making this adjustment for the remainder
of 2006 to enhance investors' understanding of the comparability between 2006
and 2005 results. See also Attachment I, Statements of Income footnote (b) for
the six months ended June 30.
