ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         See Item 8.01, incorporated herein by reference, for information
regarding amendments to the company's excess defined benefit plans (in which
some or all of its executive officers participate), the adoption of a new excess
defined contribution plan and amendments to certain executive's employment
agreements approved on August 18, 2006 by the Compensation/Nominating/Governance
Committee of the Board of Directors of Tenneco Inc.

ITEM 8.01 OTHER EVENTS.

         On August 18, 2006, the Compensation/Nominating/Governance Committee of
Tenneco's Board of Directors approved various changes to the company's employee
benefits programs.

         The company has "frozen," effective December 31, 2006, its current
defined benefit pension plans (the "DB Plans") (preserving prior earned
benefits), replaced them with additional benefits under defined contribution
plans and made certain related amendments. The affected DB Plans are: the
Tenneco Retirement Plan for Salaried Employees, the Pension Plan for Hourly
Employees of Tenneco Employed in Racine, WI and Grass Lake, MI Locals 85 and 660
(non-union employees only), the Tenneco Inc. Supplemental Retirement Plan (the
"SERP," in which all of the company's U.S.-based executive officers participate)
and the Tenneco Inc. Supplemental Pension Plan for Management (the "KEPP," in
which three of the company's executive officers participate). With the exception
of certain executives who had employment contracts providing for specified
benefits (all of whom voluntarily accepted a benefits reduction as described
below), this freezing of DB Plan benefits impacts all U.S.-based salaried
employees (including executive officers) and non-union hourly employees who
participate in any of the DB Plans.

         To address the loss of benefits associated with the foregoing action,
the company's existing defined contribution plans (the "Existing DC Plans") have
been amended, effective January 1, 2007, to provide for additional annual
company contributions in amounts that increase with the employee's age (the "DB
Replacement Contributions"), payable in respect of each employee who ceases to
accrue benefits or whose benefits were otherwise modified under any DB Plan as
described herein. In addition, effective January 1, 2007 there will be a new,
unfunded non-qualified defined contribution pension plan (the "New DC Plan"), in
which employees of the company and its subsidiaries who have specified salary
grade designations will be eligible to participate (which will include all of
the company's executive officers except for Mr. Richard P. Schneider, as he is
already fully vested in the KEPP), with allocations under the New DC Plan
calculated the same as under the applicable Existing DC Plan (as amended),
except that (i) the compensation limit set forth in Section 401(a)(17) of the
Internal Revenue Code shall be disregarded and bonuses awarded under the Tenneco
Value Added Incentive Plan (or any successor thereto) shall be included in
calculating compensation, and (ii) there will be an offset for DB Replacement
Contributions.

         Three of the company's executive officers - Timothy R. Donovan, Hari N.
Nair and Timothy Jackson -- are parties to employment agreements with the
company. Each of Messrs. Donovan's and Jackson's employment agreements provide
for his participation in the SERP and the KEPP and further provide that the
company may not (without his consent) modify his benefits under those plans. Mr.
Nair's employment agreement provides for his participation in the SERP and
further provides that the company may not (without his consent) modify his
benefits under that plan. Accordingly, the KEPP and SERP were not frozen as
described above with respect to these executives. Instead, each individual
executive has voluntarily agreed to a reduction in his retirement benefit
payable under those plans (which reduction increases to a maximum of 5%,
depending on the executive's age at retirement) and to an offset to benefits




payable under those plans for DB Replacement Contributions received under the
Existing DC Plans or the New DC Plan. The Committee amended the KEPP and SERP,
and has authorized amendments to the employment agreement of each executive, to
give effect to this arrangement.

         One executive officer of the company -- Mr. Richard P. Schneider -- is
fully vested in the KEPP. With respect to Mr. Schneider, the company amended the
KEPP to provide, as an offset to benefits thereunder, the value of any benefits
Mr. Schneider receives in respect of DB Replacement Contributions.

         In addition, for 2007, the company will replace all current PPO and HMO
heath benefits programs in the U.S. with a single new program -- known as a
Consumer Driven Health Care (CDHC) plan. This change will impact all U.S.-based
salaried employees, non-union hourly employees and Monroe Local 878 hourly
employees.

         The company estimates that pension program changes described above will
result in annual savings of about $11 million (pre-tax). These savings will
begin to be recognized in 2007. Additionally, the company expects to record a
one-time benefit of approximately $6 million to $7 million (pre- tax) in the
fourth quarter of 2006 related to these changes. Switching to the consumer
driven health care benefits program will help the company offset an estimated $3
million increase that would have occurred in 2007 under the old plan.

         A copy of the company's press release, dated August 23, 2006, which is
filed as Exhibit 99.1 to this Current Report on Form 8-K, is incorporated herein
by reference.
