           COMPANY FORECASTS $1 BILLION IN OE BUSINESS GROWTH IN 2007

  o   EPS of 18-cents versus a loss of 45-cents a year ago
  o   EBIT up 75%
  o   Year-over-year fourth quarter cash flow from operations improved $93
      million to $158 million
  o   16th consecutive quarter of year-over-year adjusted EBITDA improvement
  o   Company anticipates OE business growth of $1 billion in 2007

LAKE FOREST, ILLINOIS, JANUARY 26, 2006 - Tenneco Inc. (NYSE: TEN) reported
fourth quarter net income of $8 million, or 18-cents per diluted share, up from
a loss of $19 million, or 45-cents per diluted share, in fourth quarter 2004.
Adjusted for the items below, net income rose to $13 million, or 28-cents per
diluted share, compared with $10 million, or 21-cents per diluted share, a year
ago (see the tables attached to the press release, which reconcile GAAP results
to non-GAAP results). Cash generated by operations in the quarter was $158
million, compared with $65 million for the same period one year ago. Working
capital improvements drove the strong cash performance including $115 million in
cash from accounts receivable and $29 million from inventory reductions.

The company's fourth quarter revenue was $1.1 billion, even with last year.
Excluding the negative impact of currency and lower margin substrate sales
(previously referred to as pass-through catalytic converter sales), quarterly
revenue increased 4% compared with the prior year.

EBIT (earnings before interest, taxes and minority interest) was $38 million
compared with $21 million in fourth quarter 2004. EBITDA (EBIT before
depreciation and amortization) was $81 million, up from $67 million the previous
year. On an adjusted basis, EBIT was $53 million, up from $49 million a year ago
and EBITDA was $96 million, up $1 million from fourth quarter 2004. For the
first time in more than three years, currency, particularly the weakening euro,
negatively impacted earnings; EBITDA was reduced by $4 million and EBIT by $2
million, compared to last year.

FOURTH QUARTER 2005 ADJUSTMENTS:
  o   Restructuring related expenses of $5 million pre-tax, or 6-cents per
      diluted share;
  o   New aftermarket customer changeover costs of $10 million pre-tax, or
      15-cents per diluted share;
  o   Tax benefit of $5 million, or 11-cents per diluted share, related to the
      favorable resolution of foreign tax contingencies.

FOURTH QUARTER 2004 ADJUSTMENTS:
  o   Restructuring related expenses of $28 million pre-tax, or 40-cents per
      diluted share;
  o   Tax benefits of $15 million, or 34-cents per diluted share, primarily to
      recognize benefits related to previous tax losses in foreign operations;
  o   Expenses of $42 million pre-tax, or 60-cents per diluted share, for
      refinancing the company's 11.625% subordinated debt to 8.625%.

Tenneco's fourth quarter results were driven by the company having a good mix of
OE business with products on stronger selling vehicles globally, new aftermarket
customers in North America and improved aftermarket ride control and emission
control volumes in Europe. The company also continues to benefit from its
ongoing manufacturing efficiency improvements and successful cost reduction
programs including restructuring and discretionary spending controls. These
efforts helped offset the negative impact of higher material costs and higher
transportation costs due to fuel surcharges.

"Our solid fourth quarter performance reflects our ongoing ability to execute
consistent strategies for generating top-line growth, controlling costs and
improving operational efficiency," said Mark P. Frissora, chairman, CEO and
President, Tenneco. "We were successful in delivering a strong cash quarter as a
result of our sharp focus on working capital improvements, particularly in
accounts receivables and inventory reduction."

At quarter-end, total debt was $1.378 billion, compared with $1.420 billion the
previous year. Debt net of cash was $1.237 billion, a modest increase versus
$1.206 billion a year ago, primarily due to OEMs terminating $88 million in
advance payment programs earlier in 2005.

The company's gross margin was 18.7%, relatively flat quarter-over quarter,
despite the negative impact from higher steel costs and fuel surcharges on
transportation costs. These factors offset savings and improved efficiencies
from Lean manufacturing, Six Sigma and other cost reduction initiatives.

Total steel cost increases in the fourth quarter were $35 million, which were
largely offset by the company's cost reduction efforts, including SGA&E
restructuring savings, material cost savings, Six Sigma program savings and Lean
manufacturing efficiencies as well as partial steel cost recovery from OE and
aftermarket customers. Based on the company's efforts to offset increased steel
costs and trends in the steel market, the company doesn't currently anticipate a
significant year-over-year impact on operating results in 2006.

Tenneco significantly improved its SGA&E (sales, general, administrative and
engineering) expense in the quarter to 11.0% of sales including 1.0% related to
aftermarket changeover costs. This was an improvement over fourth quarter 2004
SGA&E of 12.6%, which included 1.7% in restructuring costs. The improvement was
driven by cutbacks on discretionary spending and benefits from previously
announced restructuring programs.


                                      -3-

Tenneco continued to outperform its bank debt covenants in the quarter. At
December 31, the leverage ratio was 3.30, lower than the maximum limit of 4.50;
the fixed charge ratio was 2.22, exceeding the minimum ratio of 1.10; and the
interest coverage ratio was 3.41, exceeding the minimum ratio of 2.00.

NORTH AMERICA
  o   North American OE revenue was up 4% to $372 million, versus $358
      million a year ago. Excluding the impact of currency and lower margin
      substrate sales, revenue was up 8%, doubling a 4% market increase in
      light vehicle production. The increase was driven by the company's
      platform mix with products on strong selling vehicles and $10 million
      in motorcycle exhaust sales to Harley Davidson as a result of the
      company's earlier acquisition of Gabilan.
  o   North American aftermarket revenue was $113 million, up 3%
      year-over-year. Stronger ride control volumes and price increases in
      both product lines more than offset lower emission control volumes.
      During the quarter, the company aggressively leveraged its strong
      market position in North America to win new business from competitors
      with 12 customers, representing $15 million in annualized revenue. The
      changeover cost for these new customers was $10 million.
  o   EBIT for North American operations was $19 million, versus $22 million
      in fourth quarter 2004. The decline was primarily due to $10 million in
      aftermarket changeover costs. Adjusting for these changeover costs and
      restructuring expenses, EBIT was $31 million, versus $30 million in
      fourth quarter 2004.

EUROPE, SOUTH AMERICA, INDIA
  o   European OE revenue was $352 million, versus $385 million a year ago.
      Adjusted for currency, lower margin substrate sales and a change in
      reporting for a customer contract, revenue was up 6%. The increase was
      driven by the company's position on better selling ride control
      platforms as well as the production ramp-up of a new commercial vehicle
      exhaust platform.
  o   European aftermarket revenue was $76 million, versus $82 million the
      previous year. Excluding the impact of currency, revenues increased 3%.
      This improvement was largely due to stronger ride control volumes and
      price increases in both product lines.
  o   South America and India revenue was $61 million, including $7 million
      in favorable currency, compared with $50 million a year ago. Stronger
      OE volumes in both regions and increased South American aftermarket
      sales drove the increase.
  o   EBIT for Europe, South America and India was $13 million, versus a loss
      of $5 million in 2004 fourth quarter. Excluding fourth quarter
      restructuring related costs of $3 million in 2005 and $17 million in
      2004, EBIT was $16 million versus $12 million a year ago, up 33%.
      Currency negatively impacted fourth quarter 2005 EBIT by $2 million.

ASIA PACIFIC
  o   Asia operations generated $41 million in revenue, versus $31 million a
      year ago. Revenue growth of 31% was driven by stronger OE volumes in
      China due to stronger exhaust sales and the launch of a new exhaust and
      ride control platform.
  o   Australian revenue was $49 million, compared with $55 million the
      previous year. The decline was largely driven by lower market
      production volumes and a negative currency impact of $2 million.
  o   Asia Pacific EBIT was $6 million, up 50% from $4 million a year ago,
      driven by manufacturing improvements in China. 2004 EBIT included $3
      million in restructuring costs.

FULL YEAR 2005 RESULTS
For 2005, Tenneco reported record high revenue of $4.4 billion, driven by its
position on strong selling OE platforms globally as well as higher aftermarket
sales in North America and Europe. The company reported net income of $58
million, or $1.29 per diluted share, versus 2004 net income of $15 million, or
35-cents per diluted share. Full-year EBIT was $215 million, up from 2004 EBIT
of $174 million. EBITDA rose to $392 million from $351 million in 2004.

Adjusted for the items below, including lower interest expense and a change in
the reported tax rate, full year net income was $69 million, or $1.52 per
diluted share, versus $54 million, or $1.22 per diluted share, in 2004. Adjusted
EBIT was $237 million, an increase from $226 million the prior year. Adjusted
EBITDA was $414 million, versus $403 million in 2004.

FULL-YEAR 2005 ADJUSTMENTS:
  o   Restructuring and related expenses of $12 million pre-tax, or 17-cents per
      diluted share;
  o   Aftermarket changeover costs of $10 million, or 15-cents per diluted
      share;
  o  Tax benefits of $4 million, or 9-cents per diluted share.

FULL-YEAR 2004 ADJUSTMENTS:
  o   Restructuring and related expenses of $40 million pre-tax, or 56-cents per
      share, to improve manufacturing efficiency and reduce costs;
  o   Expenses of $8 million, or 12-cents per diluted share, associated with
      changeover costs for a new aftermarket customer;
  o   Expenses of $4 million pre-tax, or 6-cents per diluted share, for
      consulting fees indexed to the stock price based on a 1999 agreement for
      implementing EVA(R);
  o   Tax benefits of $21 million or 47-cents per diluted share;
  o   Expenses of $42 million pre-tax, or 60-cents per diluted share for
      refinancing the company's subordinated debt.

Gross margin for the year was 19.3% versus 20.1% a year ago, largely impacted by
higher material costs. The company reported SGA&E for the year of 10.5% of
sales, including 0.2% in aftermarket changeover costs, compared with 11.7% in
2004, which included 0.6% primarily related to restructuring costs. In 2005,
Tenneco realized $32 million in savings from Six Sigma programs and $35 million
in incremental savings from restructuring actions.

"We had a very successful year in 2005 and were able to maintain positive
momentum with solid year-over-year earnings and operational improvements in the
face of difficult conditions including material price increases, the
cancellation of our advance payment programs and an uncertain operating
environment," said Frissora. "We also strengthened our growth prospects by
winning significant new business including contracts in our targeted growth
areas of diesel aftertreatment and electronic suspension systems."

2006 OUTLOOK
In 2006, Tenneco plans to continue growing its businesses with advanced
technologies and by expanding in new markets and with fast-growing customers. At
the same time, the company will continue its intense focus on controlling costs,
improving operational efficiency and leveraging its global supply chain
spending. The company's goals include maintaining SGA&E as a percent of sales
below 10.3%; achieving a net debt/EBITDA ratio of 2.8x; and generating at least
$300 million in new annual business.

Tenneco estimates that its global original equipment revenues will be
approximately $3.5 billion in 2006 and $4.5 billion in 2007. Adjusted for lower
margin substrate sales, the company's global original equipment revenues are
estimated to be approximately $2.7 billion in 2006 and $3.1 billion in 2007.
These revenue estimates are based on original equipment manufacturers' programs
that have been formally awarded to the company; programs where the company is
highly confident that it will be awarded business based on informal customer
indications consistent with past practices; Tenneco's status as supplier for the
existing program and its relationship with the customer; and the actual original
equipment revenues achieved by the company for each of the last several years
compared to the amount of those revenues that the company estimated it would
generate at the beginning of each year. These revenue estimates are also based
on anticipated vehicle production levels and pricing, including precious metals
pricing and the implementation of certain actions to recover a portion of
material cost increases. The revenue estimates assume that foreign currency
exchange rates will remain constant over the entire period.

"The operating environment for automotive supply companies remains as
challenging as ever with a lot of uncertainty in the North American markets,"
said Frissora. "Our formula for success remains unchanged. We will continue
focusing on those areas within our control, executing with discipline on the
fundamentals and maintaining a relentless focus on controlling costs. We should
also continue to benefit from our balance and diversification in terms of
products, markets served and our customer base as well as from a strong new
product and technology pipeline designed to help Tenneco win incremental OE and
aftermarket business."

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;



                                      -7-

(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, 2004. Further

(1) Generally Accepted Accounting Principles

(2) Tenneco Inc. presents the above reconciliation of GAAP to non-GAAP earnings
measures in order to reflect the results for the fourth quarters of 2005 and
2004 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 Inc. has presented EBITDA because it regularly reviews
EBITDA as a measure of the company's performance. In addition, Tenneco Inc.
believes its debt holders utilize and analyze our EBITDA for similar purposes.
Tenneco Inc. 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.

Tenneco Inc. 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. While Tenneco Inc. original equipment customers assume the risk of
this volatility, it impacts reported revenue. Excluding substrate sales removes
this impact. Tenneco Inc. uses this information to analyze the trend in revenues
before these factors. Tenneco Inc. 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 Inc. 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 fourth quarter of 2004, Tenneco Inc. recorded
$15 million in revenues for this contract.

(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 Inc. has presented EBITDA because it regularly reviews
EBITDA as a measure of the company's performance. In addition, Tenneco Inc.
believes its debt holders utilize and analyze our EBITDA for similar purposes.
Tenneco Inc. 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 Inc. presents the above reconciliation of GAAP to non-GAAP earnings
measures in order to reflect the results for the twelve months of 2005 and 2004
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 have a disproportionate positive or
negative impact on the company's financial results in any particular period.


(3)See Reconciliation of GAAP Net Income to EBITDA on previous page. 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 Inc. believes
its debt holders utilize and analyze our EBITDA for similar purposes. Tenneco
Inc. 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 calculation.

Tenneco Inc. 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. While Tenneco Inc. original equipment customers assume the risk of
this volatility, it impacts reported revenue. Excluding substrate sales removes
this impact. Tenneco Inc. uses this information to analyze the trend in revenues
before these factors. Tenneco Inc. 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 Inc. 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 second, third and fourth quarters of 2004,
Tenneco Inc. recorded $42 million in revenues for this contract.
