                             TENNECO AUTOMOTIVE INC.
                    SUPPLEMENTAL PENSION PLAN FOR MANAGEMENT

                                     Purpose

     The Tenneco Automotive Inc. Supplemental Pension Plan for Management (the
"Plan") is hereby established by Tenneco Automotive Inc. (the "Company")
effective January 1, 2005. The Plan is an unfunded plan for the purpose of
providing retirement benefits with respect to certain employees. The benefits
provided under the Plan are only available to a "select group of management or
highly compensated employees" as determined by the Compensation/Nominating/
Governance Committee of the Board of Directors of the Company (the "Committee"),
and the Plan is intended to satisfy the exemption requirements of the Employee
Retirement Income Security Act of 1974, as amended, for a plan limited to such a
group.

                                    The Plan

1.   Effective Date.

     The Plan as set forth herein is effective as of January 1, 2005 (the
"Effective Date").

2.   Eligibility.

     The employees indicated on Appendix A, attached hereto, shall be eligible
to participate in the Plan as of the Effective Date. After the Effective Date,
the Committee, in its discretion, shall determine which other employees are
eligible to participate in the Plan, provided that such employees also satisfy
the eligibility and participation requirements of the Tenneco Automotive Inc.
Retirement Plan for Salaried Employees (the "Salaried Retirement Plan"). All
employees that are listed on Appendix A or that are selected by the Committee
under this Section 2 shall be deemed "Participants" under the Plan.

3.   Plan Benefit.

     Subject to the terms and conditions of the Plan, the retirement benefit
payable under the Plan (the "Plan Benefit") to any Participant shall be an
amount equal to the excess, if any, of (a) over (b) where:

     (a)  is an amount equal to 4% of the Participant's Compensation (as defined
          below) times the Participant's Years of Service (as determined in
          accordance with the terms of the Salaried Retirement Plan; and

     (b)  is the total amount (if any) that is payable under the Tenneco
          Retirement Plan (or any successor thereto), the Salaried Retirement
          Plan (or any successor thereto), the Tenneco Automotive Inc. Key
          Executive Pension Plan, the Tenneco

<PAGE>

          Automotive Inc. Supplemental Executive Retirement Plan and the Tenneco
          Automotive Inc. Supplemental Retirement Plan, including any special
          supplemental benefit payable with respect to the Participants.

          For purposes of the Plan, the term "Compensation" with respect to any
     Participant means the average annual base salary and bonus paid to the
     Participant by the Company and its affiliates for the three year period (or
     if less, his total period of employment with the Company and its
     affiliates) ending on the date on which his employment with the Company and
     its affiliates terminates for any reason (the "Termination Date").
     Notwithstanding the foregoing provisions of this Section 3, in no event
     shall the amount determined under paragraph (a) next above with respect to
     any Participant exceed 50% of the Participant's Compensation

4.   Payment and Calculation of Plan Benefits.

     The Plan Benefit shall be payable in the form of a single lump sum payment
and shall be payable as soon as practicable after the later of (a) a
Participant's Termination Date or (b) the date on which he attains age 55;
provided, however, that with respect to any Participant who is a "key employee"
as defined by Section 409A(a)(2)(B)(i) of the Code, payment of any benefit shall
be made no earlier than six months from Participant's Termination Date with the
Company.

     The single lump sum payment shall be calculated using the applicable
interest rate (as defined in Section 417(e)(3)(A)(ii)(II) of the Internal
Revenue Code (the "Code")) for the second calendar month preceding the first day
of the calendar year during which the benefit payments are to commence and the
applicable mortality table (as defined in Section 417(e)(3)(A)(ii)(I) of the
Code).

5.   Surviving Spouse Death Benefits.

     If a Participant dies before the date as of which payment of his Plan
Benefit is to be paid under the Plan and there is an Eligible Spouse (as defined
in the Salaried Retirement Plan), a "Surviving Spouse Death Benefit" shall be
paid to the Eligible Spouse; provided however, that payment of the Surviving
Spouse Death Benefit shall not be made prior to the date on which the
Participant would have attained age 55. The Surviving Spouse Death Benefit
payable to an Eligible Spouse under the Plan shall be the actuarial equivalent
of 50% of the monthly benefit amount to which the Participant would have been
entitled if:

     (a)  he had commenced receipt of his Plan Benefit as of the date on which
          he attained age 55;

     (b)  his benefit was paid in the form of a Qualified Joint and Survivor
          Benefit (as defined in the Salaried Retirement Plan); and

     (c)  his benefit was based on his Years of Service and Compensation as of
          the actual date of his death (or, if earlier, his Termination Date).

<PAGE>

The Surviving Spouse Death Benefit shall be calculated and payable in accordance
with the rules set forth in Section 4 above.

6.   Termination of Participation in 2005.

     If a Participant separates from service with the Company in 2005, such
Participant may elect, in a writing filed with the Committee, to terminate
his/her participation in the Plan for 2005. Any amounts would be payable to the
Participant and subject to immediate taxation.

7.   Unfunded Plan.

     This Plan shall be maintained as an unfunded non-qualified deferred
compensation plan. All benefits under this Plan shall be payable from the
general assets of the Company. No benefit hereunder shall be paid from the funds
of any qualified plan maintained by the Company.

8.   No Assignment.

     No benefit under this Plan shall be assignable or alienable or subjected,
by attachment or otherwise, to the claims of creditors of any person.

9.   No Guarantee of Employment.

     This Plan shall not be construed to give any Participant the right to be
retained in the employment of the Company or any of its affiliates.

10.  Operation and Administration.

     The Plan shall be operated under the direction of and administered by the
Committee.

     The Committee shall have the sole and complete authority and discretion to
interpret the terms and provisions of the Plan and to adopt, alter and repeal
such administrative rules, regulations and practices governing the operation of
the Plan, and to determine facts under the Plan as it shall from time to time
deem advisable.

     The Committee's decision in all matters involving the interpretation and
application of this Plan shall be final and binding. The Committee shall
establish a claims procedure which is consistent with the claims procedures
employed under the Salaried Retirement Plan.

<PAGE>

11.  Governing Law.

     To the extent permitted by federal law, this Plan shall be construed,
administered and enforced in accordance with the laws of the State of Illinois.

12.  Amendment and Discontinuance.

     The Company reserves the right, by action of the chief executive officer,
to amend or discontinue the Plan. However, no such amendment or discontinuance
shall impair or adversely affect any benefits accrued under this Plan as of the
date of such action.

     IN WITNESS WHEREOF, the Company has cause this Plan to be executed on its
behalf by the respective officers thereunder duly authorized, as of the
Effective Date.

<PAGE>

                 TENNECO AUTOMOTIVE INC. INCENTIVE DEFERRAL PLAN

1.   PURPOSE

Effective January 1, 2005, Tenneco Automotive Inc. (the "Company") hereby
establishes the Tenneco Automotive Inc. Incentive Deferral Plan (the "Plan").
The purpose of the Plan is to provide directors and a select group of management
or highly compensated employees of the Company and its subsidiaries and
affiliates (hereinafter collectively referred to as the "Company") an
opportunity to defer compensation received by them from the Company in
accordance with the terms and conditions set forth herein.

2.   ADOPTION AND ADMINISTRATION

The Plan shall be administered by the Compensation/Nominating/Governance
Committee of the Board of Directors of the Company (the "Committee"). The
Committee shall have the sole and complete authority and discretion to interpret
the terms and provisions of the Plan and to adopt, alter and repeal such
administrative rules, regulations and practices governing the operation of the
Plan, and to determine facts under the Plan as it shall from time to time deem
advisable.

3.   ELIGIBILITY

Directors and executive incentive level U.S. participants in the Company's Value
Added ("TAVA") Incentive Compensation Plan shall be eligible to participate in
the Plan. Further, any person who had an account balance in the Tenneco
Automotive Inc. Deferred Compensation Plan may participate in this Plan.

Persons eligible to participate in the Plan shall be referred to as
"Participant" or "Participants" as the case may be.

4.   ELECTION TO DEFER

A Participant may elect in writing to defer receipt of all or a specified
portion of his or her bonuses or incentive compensation to be received with
respect to a calendar year ("Deferral Election"); provided, however, that any
election by a Participant who is subject to the reporting and short swing
profits liability provisions of Section 16 of the Securities and Exchange Act of
1934, as amended, including an election relating to the form of distribution or
to defer income into an "Automotive stock index account" pursuant to Section 6
of the Plan, shall not be effective until such election and the transactions
contemplated thereby shall have been specifically approved by the Committee to
the extent such approval is required to avoid liability under Section 16 of the
Securities and Exchange Act of 1934 and the regulations thereunder. Once
received by the Committee, a Deferral Election cannot be revoked. A Deferral
Election (including Committee approval) must be made prior to June 30 of the
calendar year in which the bonus or incentive compensation will be awarded. A
Participant must make a separate Deferral Election with respect to each calendar
year of participation in the Plan. A new Participant in the Plan shall have 30
days following his or her notification by the Committee of his or her
eligibility to participate in the Plan to make a Deferral Election with respect
to bonus or incentive

<PAGE>

compensation to be awarded within that calendar year. Amounts deferred under the
Plan shall be referred to as the "Deferred Amounts."

5.   OUTSIDE DIRECTORS

Directors who are not employees of the Company or its subsidiaries (hereinafter
referred to as "Outside Directors") will receive as part of their compensation
for service on the Company's Board of Directors sixty (60) percent of their
annual retainer fee in the form of credits deferred subject to the terms of this
Plan in the Automotive stock index account. Amounts credited to the Automotive
stock index account under this Section 5 will be settled either in cash or, if
the Company so elects, shares of the Company's common stock and will be offered
under the Company's principal equity incentive plan then in effect.

6.   ESTABLISHMENT OF DEFERRED COMPENSATION ACCOUNT

At the time of a Participant's initial Deferral Election, the Company shall
establish a memorandum account (a "Deferred Compensation Account") for such
Participant on its books. The Deferred Amount shall be credited to the
Participant's Deferred Compensation Account as of the day on which the
Participant would otherwise be entitled to receive the bonus or incentive
compensation. Any required withholding for taxes (e.g. Social Security taxes) on
the Deferred Amount shall be made from other compensation of the Participant.
Adjustments as provided below, shall be made to the Participant's Deferred
Compensation Account.

7.   ADJUSTMENTS TO DEFERRED AMOUNTS

The Committee shall credit the balance of the Participant's Deferred
Compensation Account with an earnings factor. The earnings factor will equal the
amount the Participant's Deferred Compensation Account would have earned if it
had been invested in the investment options listed below. The Participant is
permitted to select the investment option used to determine the earnings factor
and may change the selection at any time. The Participant may choose more than
one investment option in increments of at least one (1) percent. The Company
reserves the right to change or amend any of the investment options at any time.
The investment options used to determine the earnings factor are:

     (a)  The prime rate of interest as reported by JPMorgan Chase Bank at the
          first day of each calendar month.

     (b)  Automotive stock index account - the amount of deferral will be
          invested in Tenneco Automotive Inc. stock equivalent unit account. Any
          investment in this account will be measured solely by the performance
          of the Company's common stock (including dividends that will be
          reinvested). Amounts credited to this account will be settled either
          in cash or, if the Company so elects, shares of the Company's common
          stock and will be offered under the Company's principal equity
          incentive plan then in effect.

                                       2

<PAGE>

     (c)  The return for the following investment funds:

          (i)   JPMorgan Chase Prime Rate Fund

          (ii)  Putnam Bond Index Fund

          (iii) Putnam S&P 500 Index Fund

     The Company is under no obligation to acquire or provide any of the
     investments designated by a Participant, and any investments actually made
     by the Company will be made solely in its name and will remain its
     property.

     The crediting of an earnings factor shall occur so long as there is a
     balance in the Participant's Deferred Compensation Account regardless of
     whether the Participant has terminated employment.

8.   PAYMENT OF DEFERRED AMOUNTS

     (a)  Subject to the subsection (b) below, a Participant's Deferred Amount
          shall be paid in a single lump sum payment to the Participant, or the
          Participant's beneficiary, as soon as practicable after:

          (i)   the Participant's death,
          (ii)  the termination of the Participant's employment or service as a
                director, or
          (iii) the date specified in the applicable Deferral Election made by
                the Participant.

     (b)  Notwithstanding Section 8(a), with respect to any Participant who is a
          "key employee" as defined by Section 409A(a)(2)(B)(i) of the Code,
          payment of such Participant's Deferred Amount shall be made no earlier
          than six months from Participant's separation from service with the
          Company.

9.   TERMINATION OF PARTICIPATION IN 2005

If a Participant separates from service with the Company in 2005, such
Participant may elect, in a writing filed with the Committee, to terminate
participation in the Plan and revoke any Deferral Election for 2005. Any amounts
would be payable to the Participant and subject to immediate taxation.

                                       3
<PAGE>

10.  PARTICIPANT REPORTS

The Committee shall provide a statement to the Participant quarterly concerning
the status of his or her Deferred Compensation Account.

11.  TRANSFERABILITY OF INTERESTS

During the period of deferral, all Deferred Amounts shall be considered as
general assets of the Company for use as it deems necessary and shall be subject
to the claims of its creditors. The rights and interests of a Participant during
the period of deferral shall be those of a general unsecured creditor except
that such Participant's rights and interests may not be reached by the creditors
of the Participant or the Participant's beneficiary, or anticipated, assigned,
pledged, transferred or otherwise encumbered except in the event of the death of
the Participant, and then only by will or the laws of descent and distribution.

12.  AMENDMENT, SUSPENSION AND TERMINATION

The Company, at any time, through action of the Committee, may amend, suspend or
terminate the Plan or any portion thereof in such manner and to such extent as
it may deem advisable and in its best interests. No amendment, suspension and
termination shall reduce the Deferred Amount then credited to a Participant's
Deferred Compensation Account.

13.  UNFUNDED OBLIGATION

The Plan shall not be funded; no trust, escrow or other provisions shall be
established to secure payments due under the Plan; and the Plan shall be
regarded as unfunded for purposes of the Employee Retirement Income Security Act
of 1974, as amended, and the Internal Revenue Code. A Participant shall be
treated as a general, unsecured creditor at all times under the Plan, and shall
have no rights to any specific assets of the Company. All amounts credited to
the memorandum accounts of the Participants will remain general assets of the
Company and shall be payable solely from the general assets of the Company.

14.  NO RIGHT TO EMPLOYMENT OR OTHER BENEFITS

Nothing contained herein shall be construed as conferring upon any Participant
the right to continue in the employ of the Company. Any compensation deferred
and any payments made under this Plan shall not be included in creditable
compensation in computing benefits under any employee benefit plan of the
Company except to the extent expressly provided therein.

15.  DISPUTE RESOLUTION

By participating in the Plan, the Participant agrees that any dispute arising
under the Plan shall be resolved by binding arbitration in Lake Forest, Illinois
under the rules of the American Arbitration Association and that there will be
no remedy besides the disputed deferred compensation amount in issue.

its behalf by its respective officers thereunder duly authorized, as of the
