NOTE: All other schedules required by Section 2520.103-10 of the Department of

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Participants of
The Tenneco Employee Stock Ownership Plan for Hourly Employees:

We have audited the accompanying statements of net assets available for benefits
of The Tenneco Employee Stock Ownership Plan for Hourly Employees (the "Plan")
as of December 31, 2005 and 2004, and the related statement of changes in net
assets available for benefits for the year ended December 31, 2005. These
financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. The Plan is not required to have,
nor were we engaged to perform, an audit of its internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Plan's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets of the Plan at December 31, 2005 and 2004, and the
changes in net assets available for benefits for the year ended December 31,
2005 in conformity with accounting principles generally accepted in the United
States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) as of December 31, 2005 is presented for the purpose of
additional analysis and is not a required part of the basic financial
statements, but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This schedule is the responsibility of
the Plan's management. Such schedule has been subjected to the auditing
procedures applied in our audit of the basic 2005 financial statements and, in
our opinion, is fairly stated in all material respects when considered in
relation to the basic financial statements taken as a whole.

THE TENNECO EMPLOYEE STOCK
OWNERSHIP PLAN FOR HOURLY EMPLOYEES

NOTES TO FINANCIAL STATEMENTS
AS OF DECEMBER 31, 2005 AND 2004, AND FOR THE YEAR ENDED DECEMBER 31, 2005

1.   DESCRIPTION OF THE PLAN

     The following description of The Tenneco Employee Stock Ownership Plan for
     Hourly Employees (the "Plan") is provided for general information purposes
     only. Participants should refer to the Plan Document for more complete
     information.

     GENERAL--The Plan is a defined contribution plan covering substantially all
     hourly employees of Tenneco Inc. (the "Company"). The Company controls and
     manages the operation and administration of the Plan. Putnam Fiduciary
     Trust Company serves as the trustee of the Plan. The Plan is subject to the
     provisions of the Employee Retirement Income Security Act of 1974
     ("ERISA").

     ELIGIBILITY--Employees are eligible to participate in the Plan the first
     day of the month following the Company's receipt of an application for
     enrollment or two complete calendar months of employment provided the
     employee has not waived automatic enrollment. Certain union employees are
     subject to different eligibility provisions, as defined in the Plan
     Document.

     CONTRIBUTIONS--An employee is automatically enrolled in the Plan upon
     completion of the eligibility requirements at a pretax contribution rate of
     2% of pretax annual compensation, as defined in the Plan Document, subject
     to certain Internal Revenue Code limitations, unless the employee elects to
     waive automatic enrollment prior to the effective date. Participants can
     elect to increase the pretax deferral rate, subject to certain Internal
     Revenue Code limitations, from 2% up to 100% in any whole percentage, at
     any time.

     The Company's matching contribution is 50% of the participant's
     contributions, not to exceed 8% of the participant's base compensation.
     Certain union employees are not eligible for the Company's matching
     contribution, as defined in the Plan Document. Additional amounts may be
     contributed at the discretion of the Company. No such additional
     discretionary contributions were made for the year ended December 31, 2005.
     Participants may also roll over amounts from other qualified plans.

     Company matching contributions are made in cash. All Company matching
     contributions of Company common stock made prior to January 1, 2002, and
     the related earnings/losses will remain in the form of the Company's common
     stock until the participant reaches age 55 or terminates employment and
     requests a total distribution.

     PARTICIPANT ACCOUNTS--Individual accounts are maintained for each Plan
     participant. Each participant's account is credited with the participant's
     contribution, the Company's matching contribution, and allocations of
     Company discretionary contributions and Plan earnings, and charged with
     withdrawals and an allocation of Plan losses and administrative expenses.
     Allocations are based on participant earnings or account balances, as
     defined. The benefit to which a participant is entitled is the benefit that
     can be provided from the participant's vested account.

     INVESTMENTS--Participants direct the investment of their contributions and
     the Company's matching contributions into various investment options
     offered by the Plan. The Plan currently offers participants


                                       -4-



     the option to invest their contribution into the following funds: Putnam
     Money Market Fund, Putnam Bond Index Fund, Lord Abbett Mid Cap Value Fund,
     Lord Abbett Small Cap Value Fund, PIMCO Total Return Fund, Putnam Equity
     Income Fund, The George Putnam Fund of Boston, Fidelity Growth Company
     Fund, Fidelity Low-Priced Stock Fund, BBH Inflation Index Securities Fund,
     MSIF Mid Cap Growth Value Portfolio, MSIF Inc. Small Company Growth Value
     Fund, Putnam Retirement Ready Maturity Fund, Putnam Retirement Ready 2010,
     Putnam Retirement Ready 2015, Putnam Retirement Ready 2020, Putnam
     Retirement Ready 2025, Putnam Retirement Ready 2030, Putnam Retirement
     Ready 2035, Putnam Retirement Ready 2040, Putnam Retirement Ready 2045,
     Putnam Retirement Ready 2050, Putnam Income Fund, Putnam Limited Duration
     Government Fund CL A, Putnam International Equity Fund, Putnam New
     Opportunities Fund, Putnam Research Fund, Putnam S&P 500 Index Fund, and
     Tenneco Inc. Common Stock Fund.

     Shares of Pactiv Corporation common stock are held by the Plan in a
     separate fund due to a transfer of participant account balances from
     another defined contribution plan in 2000; however, the fund is no longer
     an investment option for participants and direct contributions or fund
     transfers are not allowed.

     VESTING--Participants are vested immediately in both their contributions
     plus actual earnings thereon and the Company's matching contribution
     portion of their accounts.

     PARTICIPANT LOANS--Active participants and certain other individuals who
     have not had a loan during the previous three months may borrow from their
     accounts up to a maximum of $50,000 less their highest outstanding loan
     balance in the previous 12 months or 50% of their account balance,
     whichever is less. Each participant may have only one loan outstanding at
     any time, with a term not to exceed 54 months and the amount of the loan
     may not be less than $1,000. The loans are secured by the balance in the
     participant's account and bear interest at rates equal to the prime rate as
     reported in The Wall Street Journal (ranging from 4.00% to 9.50 % at
     December 31, 2005) at the time the loan is made. Principal and interest is
     paid ratably through payroll deductions.

     TERMINATION OF PARTICIPATION--Prior to March 28, 2005, upon termination of
     service due to death, disability, retirement, or termination of employment,
     a participant was permitted to elect either to receive a lump-sum amount
     equal to the value of the participant's vested interest in his or her
     account, or maintain the account, if the participant's vested interest in
     the account was more than $5,000. If the participant's account was less
     than $5,000, the participant was required to receive a lump-sum amount or
     roll over the amount to another qualified plan or IRA. At December 31,
     2004, the amount owed to participants whose service has been terminated was
     $84,977 for accounts with balances less than $5,000. Effective March 28,
     2005, Tenneco amended the Plan to reduce the mandatory lump-sum payout
     requirement from $5,000 to $1,000. As a result, at December 31, 2005 the
     amount owed to participants whose service had been terminated was $56,201.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF ACCOUNTING--The accompanying financial statements have been
     prepared in accordance with accounting principles generally accepted in the
     United States of America.

     USE OF ESTIMATES--The preparation of financial statements in conformity
     with accounting principles generally accepted in the United States of
     America requires Plan management to make estimates and assumptions that
     affect the reported amounts of net assets available for benefits and
     changes therein. Actual results could differ from those estimates. The Plan
     utilizes various investment instruments. Investment securities, in general,
     are exposed to various risks, such as interest rate, credit, and overall
     market volatility. Due to the level of risk associated with certain
     investment securities, it is reasonably


                                       -5-



     possible that changes in the values of investment securities will occur in
     the near term and that such changes could materially affect the amounts
     reported in the financial statements.

     INVESTMENT VALUATION AND INCOME RECOGNITION--Quoted market prices are used
     to determine the fair value of the Plan's investments, when available.
     Shares of registered investment companies and common/collective trusts are
     valued at the net asset value of shares held by the Plan at year-end.
     Participant loans are valued at the outstanding loan balances.

     Purchases and sales of securities are recorded on a trade-date basis.
     Interest income is recorded on the accrual basis. Dividends are recorded on
     the ex-dividend date.

     Management fees and operating expenses charged to the Plan for investments
     in registered investment companies sponsored by the Company's trustee,
     Putnam Fiduciary Trust Company, are deducted from income earned on a daily
     basis and are not separately reflected. Consequently, these management fees
     and operating expenses are reflected as a reduction of net appreciation
     (depreciation) in the fair market value of investments for such
     investments.

     ADMINISTRATIVE EXPENSES--Administrative expenses of the Plan are paid by
     the Plan as provided in the Plan Document.

     PAYMENT OF BENEFITS--Benefit payments to participants, including deemed
     distributions of participant loans, are recorded upon distribution. The
     amount allocated to accounts of persons who have elected to withdraw from
     the Plan but have not yet been paid were $56,201 and $84,977 at December
     31, 2005 and 2004, respectively. There were deemed distributions of
     participant loans in default of $172,363 and $145,028 at December 31, 2005
     and 2004, respectively.

     TRANSFERS--The Company also sponsors an employee stock ownership plan for
     salaried employees. If employees change hourly or salaried status during
     the year, their account balances are transferred into the corresponding
     plan. For the year ended December 31, 2005, plan transfers to the salaried
     plan were $287,488 and loan rollovers from Gabilan were $124,185.

3.   INVESTMENTS

     The Plan's investments that represented 5% or more of the Plan's net assets

5.   RELATED-PARTY TRANSACTIONS

     Certain Plan investments are shares of registered investment companies and
     common/collective trusts managed by Putnam Fiduciary Trust Company. Putnam
     Fiduciary Trust Company is the trustee as defined by the Plan and,
     therefore, these transactions qualify as party-in-interest transactions.
     Fees paid by the Plan for investment management services were included as a
     reduction of the return earned on each of these funds.

     At December 31, 2005 and 2004, the Plan held 1,981,686 and 2,192,918
     shares, respectively, of common stock of Tenneco Inc., the sponsoring
     employer, with a cost basis of $11,759,749 and $10,915,260, respectively.

6.   PLAN TERMINATION

     Although it has not expressed any intention to do so, the Company has the
     right under the Plan to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions set forth in ERISA. Any assets
     which are not allocated to the accounts of participants upon the complete
     termination of the Plan, or complete discontinuance of contributions, will
     be allocated among all of the participant accounts pro rata on the basis of
     their respective balances.


                                       -7-



7.   FEDERAL INCOME TAX STATUS

     The Internal Revenue Service has determined and informed the Company by a
     letter dated April 30, 2002, that the Plan and related trust, as then
     designed, were in accordance with the applicable sections of the Internal
     Revenue Code. Although the Plan has been amended since receiving the
     determination letter, the Plan administrator and the Plan's tax counsel
     believe that the Plan is currently designed and being operated in
     compliance with the applicable requirements of the Internal Revenue Code
     and is tax-exempt. Therefore, no provision for income taxes has been
     included in the Plan's financial statements.

8.   ACQUISITION OF GABILAN MANUFACTURING COMPANY

     In February 2005, Tenneco acquired substantially all the assets and assumed
     certain related liabilities of Gabilan Manufacturing Inc., a privately held
     company that had developed and manufactured motorcycle exhaust systems for
     Harley-Davidson motorcycles since 1978. The company also produced
     aftermarket muffler kits for Harley-Davidson.

     Employees of Gabilan and the administration of their payroll and benefits
     was assumed by Tenneco on April 1, 2005. At that time, Gabilan employees
     had the opportunity to roll-over their balances in the Gabilan 401(k)
     program into either the Tenneco Employee Stock Ownership Plan for Hourly
     Employees or the Tenneco Employee Stock Ownership Plan for Salaried
     Employees depending on whether the employee was categorized as hourly or
     salaried. Gabilan employees were also allowed to roll-over their 401(k)
     loans as part of the roll-over of their assets. The total rollover into the
     Tenneco Hourly Plan related to Gabilan employees totaled $1,336,596 for the
     year ended December 31, 2005.

9.   SUBSEQUENT EVENT

     Effective April 1, 2006, the Plan's trustee changed from Putnam Fiduciary
     Trust Company to ACS (Mellon). The assets were transferred to ACS (Mellon)
     on March 24, 2006.
