                                   BACKGROUND

     During 1999, Tenneco Inc. separated its automotive, packaging and
administrative services operations. This completed a series of transactions
begun in December 1996, when the company then known as Tenneco Inc. ("Old
Tenneco") separated its automotive and packaging operations from its energy and
shipbuilding businesses.

     The final separation was accomplished in November 1999 through the spin-off
of Pactiv Corporation (the "Spin-Off"), which at the time was known as Tenneco
Packaging Inc. and held Tenneco Inc.'s packaging and administrative services
businesses. Immediately following the Spin-Off, Tenneco Inc. changed its name to
"Tenneco Automotive Inc." to reflect the fact that the continuing operations are
its automotive business. In light of the form of this transaction, the Company
is the continuing legal entity which from December 1996 until the Spin-Off was
known as Tenneco Inc.

                                    (ITEM 1)

     On March 9, 2004, the Board of Directors increased its size from nine to
ten members, and Mr. Timothy R. Donovan was elected as a director of the
Company. Nine of the Company's current directors are proposed to be elected at
this Annual Meeting to serve for a term to expire at the annual meeting of
stockholders to be held in 2005 and until their successors are chosen and have
qualified. One of the current directors, Sir David Plastow, will be retiring
effective at the Annual Meeting due to having nearly reached the Company's age
limitation for Board membership and accordingly is not standing for reelection.
The Board of Directors has established the size of the Board as nine members
effective upon Sir David's retirement.

     The persons named as proxy voters in the accompanying Proxy card, or their
substitutes, will vote your Proxy for all the nominees, each of whom has been
designated as such by the Board of Directors, unless otherwise indicated in your
Proxy. In the event that any nominee for director withdraws or for any reason is
not able to serve as a director, the Company will vote your Proxy for the
remainder of those nominated for director (except as otherwise indicated in your
Proxy) and for any replacement nominee designated by the
Compensation/Nominating/Governance Committee of the Board of Directors.

     You may vote for or withhold your vote from any or all of the director
nominees. Assuming a quorum is present, the affirmative vote of the plurality of
votes cast at the Annual Meeting (in person or by proxy) will be required for
the election of directors.

     Brief statements setting forth the age (at March 19, 2004), the principal
occupation, the employment during at least the past five years, the year in
which first elected a director and other information concerning each nominee
appears below.

     THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR ALL OF THE NOMINEES

CORPORATE GOVERNANCE OVERVIEW

     The Company has established a comprehensive corporate governance plan for
the purpose of defining responsibilities, setting high standards of professional
and personal conduct and assuring compliance with such responsibilities and
standards. As part of its annual review process, the Board of Directors monitors
developments in the area of corporate governance. In late 2003, the Securities
and Exchange Commission ("SEC") approved changes proposed by the New York Stock
Exchange ("NYSE") to its corporate governance and listing requirements. Although
many of these changes are not effective as of the date of this Proxy Statement,
the Board of Directors determined to voluntarily implement these changes on an
accelerated basis, to the extent the Company's practices were not already in
compliance. Listed below are some of the key elements of the Company's corporate
governance plan. Many of these matters are described in more detail elsewhere in
this Proxy Statement.

     INDEPENDENCE OF DIRECTORS (SEE P. 8)

     - Eight of the Company's ten current directors are independent under the
       revised NYSE listing standards. Assuming all nominees presented in this
       Proxy Statement are elected at the Annual Meeting, seven of the Company's
       nine directors will be independent under the revised NYSE listing
       standards.

     - Non-management directors are scheduled to meet separately in executive
       session after every regularly scheduled Board of Directors meeting.

     - The Company has a lead outside director, Mr. Paul T. Stecko.

     AUDIT COMMITTEE (SEE PP. 10-11 AND 34-38 AND APPENDIX A)

     - All members meet the independence standards for audit committee
       membership under the revised NYSE listing standards and applicable SEC
       rules.

     - One member of the Audit Committee, Mr. Charles Cramb, qualifies as an
       "audit committee financial expert," as defined in the SEC rules, and the
       remaining members of the Audit Committee satisfy the NYSE's financial
       literacy requirements.

     - The Audit Committee operates under a written charter that governs its
       duties and responsibilities, including its sole authority to appoint,
       review, evaluate and replace the Company's independent auditors.

     - The Audit Committee has adopted policies and procedures governing the
       pre-approval of all audit, audit-related, tax and other services provided
       by the Company's independent auditors.

                                        6


     COMPENSATION/NOMINATING/GOVERNANCE COMMITTEE (SEE PP. 9, 11-12 AND 24-31
     AND APPENDIX B)

     - All members meet the independence standards for compensation and
       nominating committee membership under the revised NYSE listing standards.

     - The Compensation/Nominating/Governance Committee operates under a written
       charter that governs its duties and responsibilities, including the
       responsibility for executive compensation.

     CORPORATE GOVERNANCE PRINCIPLES

     - The Company has adopted Corporate Governance Principles, including
       qualification and independence standards for directors.

     COMMUNICATION WITH DIRECTORS (SEE P. 12)

     - The Audit Committee has established a process for confidential and
       anonymous submissions by employees of the Company, as well as submissions
       by other interested parties, regarding questionable accounting or
       auditing matters.

     - Additionally, the Board of Directors has established a process for
       stockholders to communicate with the Board of Directors, as a whole, or
       any non-management director.

     CODES OF BUSINESS CONDUCT AND ETHICS

     - The Company has adopted a Code of Ethical Conduct for Financial Managers
       that applies to the Company's Chief Executive Officer, Chief Financial
       Officer, Controller and other key financial managers.

     - The Company has operated under an omnibus Statement of Business
       Principles that applies to all directors, officers and employees and
       includes provisions ranging from restrictions on gifts to conflicts of
       interests. All employees are required to affirm in writing their
       acceptance of these principles.

     PERSONAL LOANS TO EXECUTIVE OFFICERS AND DIRECTORS

     - The Company complies with and will operate in a manner consistent with
       the recently-enacted legislation outlawing extensions of credit in the
       form of a personal loan to or for its directors or executive officers.

     GENERAL.  The Board of Directors of the Company currently comprises ten
members, eight of whom are not officers of the Company (the "Outside Directors")
and two of whom are officers of the Company (the "Inside Directors"). As
described above, one of the Outside Directors, Sir David Plastow, will be
retiring at the Annual Meeting. The Board of Directors believes that the
Company's ratio of Outside Directors to Inside Directors represents a commitment
to the independence of the Board and a focus on matters of importance to its
stockholders.

     The Board of Directors has determined that all eight of the Outside
Directors are "independent" as that term is defined under the revised listing
standards of the NYSE. As part of its analysis, the Board determined that none
of the Outside Directors has a direct or indirect material relationship with the
Company. Under written guidelines adopted by the Board, the following commercial
or charitable relationships are not considered to be material relationships that
would impair a director's independence: (i) the director is an executive officer
of another company that (directly or indirectly through its subsidiaries or
affiliates) does business with the Company and the annual sales to, or purchases
from, the Company are less than 1% of the annual consolidated revenues of both
the Company and the other company he or she serves as an executive officer; (ii)
the director is an executive officer of another company that (directly or
indirectly through its subsidiaries or affiliates) is indebted to the Company,
or to which the Company is indebted, and the total amount of either company's
consolidated indebtedness to the other is less than 1% of the total consolidated
assets of the indebted company; (iii) the director is an executive officer of
another company in which the Company owns a common equity interest, and the
amount of the Company's interest is less than 5% of the total voting power of
the other company; or (iv) the director serves as an officer, director or
trustee of a charitable organization, and the Company's discretionary charitable
contributions to the organization are less than 1% of that organization's total
annual charitable receipts. The Outside Directors do not have relationships with
the Company that are not within these guidelines.

     During 2003, the Board of Directors held nine meetings. All of the current
directors attended at least 75% of the aggregate of all meetings of the Board of
Directors and all meetings of the committees of the Board held and on which the
director served during 2003. The Board of Directors is scheduled to meet in
executive session, without management, after every Board meeting that the
directors attend in person. Mr. Stecko acts as lead outside director to chair

                                        8


these executive sessions and as primary spokesperson in communicating matters
arising out of these sessions to Company management.

     All of the directors attended last year's annual meeting of the
stockholders. The Board of Directors has a policy that, absent unusual
circumstances, all directors attend the Company's annual stockholder meetings.

     The Board of Directors has three standing committees. These committees have
the responsibilities and authority described below.

     COMPENSATION/NOMINATING/GOVERNANCE COMMITTEE.  The members of the
Compensation/Nominating/Governance Committee are Messrs. Plastow, Porter, Stecko
and Price, who is the Chairman of the Committee. The
Compensation/Nominating/Governance Committee is comprised solely of Outside
Directors who meet the independence standards for compensation and nominating
committee members as set forth in the revised NYSE listing standards.

     The Compensation/Nominating/Governance Committee has the responsibility,
among other things, to: (1) establish the salary rate of officers and employees
of the Company and its subsidiaries; (2) examine periodically the compensation
structure of the Company; (3) supervise the welfare and pension plans and
compensation plans of the Company; and (4) produce an annual report on executive
compensation for inclusion in the Company's proxy statement in accordance with
applicable rules and regulations of the SEC. It also has significant corporate
governance responsibilities including, among other things, to: (a) review and
determine the desirable balance of experience, qualifications and expertise
among members of the Board; (b) review possible candidates for membership on the
Board and recommend a slate of nominees for election as directors at each annual
meeting of stockholders; (c) review the function and composition of the other
committees of the Board and recommend membership on these committees; (d) review
the qualifications of and recommend candidates for election as officers of the
Company; and (e) develop, recommend to the Board of Directors for approval and,
as appropriate, recommend to the Board of Directors revisions to Corporate
Governance Principles applicable to the Company.

     The Compensation/Nominating/Governance Committee operates pursuant to a
written charter, the current version of which was adopted by the Board of
Directors in March 2004 as part of its annual review process, a copy of which is
included as Appendix B to this Proxy Statement. The
Compensation/Nominating/Governance Committee held six meetings during 2003. A
report of the Compensation/Nominating/Governance Committee regarding executive
compensation appears elsewhere in this Proxy Statement.

     THREE-YEAR INDEPENDENT DIRECTOR EVALUATION ("TIDE") COMMITTEE.  The members
of the TIDE Committee are Ms. Eickhoff and Messrs. Porter, Price and Stecko, who
is the Chairman of the Committee. The TIDE Committee, comprised solely of
Outside Directors, has the responsibility, among other things, to review the
Company's stockholder rights plan at least every three
                                        9


years and, if it deems it appropriate, recommend that the full Board modify or
terminate that plan. The TIDE Committee held no meetings in 2003.

     AUDIT COMMITTEE.  The members of the Audit Committee are Ms. Eickhoff and
Messrs. Macher, Severance and Cramb, who is the Chairman of the Committee. The
Audit Committee is comprised solely of directors who meet all of the
independence standards for audit committee membership as set forth in the
Sarbanes-Oxley Act of 2002, and the SEC rules adopted thereunder, and the
revised NYSE listing standards. The Board of Directors has determined that Mr.
Cramb qualifies as an "audit committee financial expert" as that term is defined
in the SEC rules adopted pursuant to the Sarbanes-Oxley Act of 2002.

     Management is responsible for the Company's internal controls over the
financial reporting process. The independent public accounting firm is
responsible for performing an independent audit of the Company's consolidated
financial statements in accordance with generally accepted audit standards and
for issuing a report on its audit. The Audit Committee's duty is to oversee and
monitor these activities on behalf of the Board of the Directors. Specifically,
the Audit Committee has the responsibility, among other things, to: (1) select
and approve the compensation of the Company's independent public accountants;
(2) review and approve the scope of the independent public accountants' audit
activity and all non-audit services; (3) review with management and the
independent public accountants the adequacy of the Company's basic accounting
system and the effectiveness of the Company's internal audit plan and
activities; (4) review with management and the independent public accountants
the Company's certified financial statements and exercise general oversight over
the financial reporting process; (5) review with the Company litigation and
other legal matters that may affect the Company's financial condition and
monitor compliance with business ethics and other policies; (6) review the
independence, qualifications and performance of the Company's independent public
accountants; (7) provide an avenue of communication among the independent public
accountants, management, the internal auditors and the Board of Directors; and
(8) prepare the audit-related report required by the SEC to be included in the
Company's annual proxy statement.

     In fulfilling its responsibilities, the Audit Committee reviewed with
management and the independent public accountants (a) significant issues, if
any, regarding accounting principles and financial statement presentations,
including any significant changes in the Company's selection or application of
accounting principles, and significant issues, if any, as to the adequacy of the
Company's internal controls and any special audit steps adopted in view of
material internal control deficiencies; (b) analyses prepared by management
and/or the independent public accountants setting forth significant financial
reporting issues and judgments made in connection with the preparation of the
financial statements, including analyses of the effects of alternative generally
accepted accounting principles methods on financial statements; (c) the effect
of regulatory and accounting initiatives, as well as off-balance sheet
structures, if any, on the financial statements of the Company; and (d) the type
and presentation of

                                        10


information to be included in earnings press releases, as well as any financial
information and earnings guidance provided to analysts and rating agencies. In
addition, the Audit Committee has discussed the Company's major risk exposures
and the steps that management has taken to monitor and control such exposures.
Management is required to advise the Committee of any instances of fraud
relating to employees who have a significant role in the Company's internal
controls. The Committee was advised that management was not aware of any such
instances of fraud.

     The Audit Committee operates under a written charter, the current version
of which was adopted by the Board of Directors in March 2004 as part of its
annual review process, a copy of which is included as Appendix A to this Proxy
Statement. The Audit Committee held ten meetings in 2003. A report of the Audit
Committee appears elsewhere in this Proxy Statement.

     CONSIDERATION OF DIRECTOR NOMINEES.  The Compensation/Nomination/Governance
Committee regularly assesses the size of the Board of Directors, the need for
expertise on the Board of Directors and whether any vacancies are expected on
the Board of Directors due to retirement or otherwise. The Committee's process
for identifying and evaluating nominees is as follows: In the case of incumbent
directors whose terms of office are set to expire, the Committee reviews such
directors' overall service to the Company during their term, including the
number of meetings attended, level of participation, quality of performance and
any transactions of such directors with the Company during their term. In the
event that vacancies are anticipated, or otherwise arise, the
Compensation/Nomination/Governance Committee considers various potential
candidates for director which may come to its attention through a variety of
sources, including current Board members, stockholders or other persons. In
addition, from time to time the Committee will retain a professional search firm
to assist it in identifying director candidates, for which the firm generally
receives a fee. All candidates for director are evaluated at regular or special
meetings of the Compensation/Nomination/Governance Committee. In evaluating and
determining whether to recommend a person as a candidate for election as a
director, the Compensation/Nomination/Governance Committee considers the
qualification standards set forth in the Company's Corporate Governance
Principles, including: (1) personal and professional ethics, integrity and
values; (2) an ability and willingness to undertake the requisite time
commitment to Board functions; (3) independence pursuant to the guidelines set
forth in the Corporate Governance Principles and applicable rules and
regulations; (4) age, which must be less than 72; (5) the potential impact of
service on the board of directors of other public companies, including
competitors of the Company; and (6) an absence of employment at a competitor of
the Company.

     The Compensation/Nominating/Governance Committee will consider director
candidates recommended by stockholders provided the procedures set forth below
are followed by stockholders in submitting recommendations. The committee does
not intend to alter the manner in which it evaluates candidates, including the
minimum criteria set forth above, based on

                                        11


whether the candidate was recommended by a stockholder. A stockholder of the
Company may nominate persons for election to the Board of Directors at an annual
meeting if the stockholder submits such nomination, together with certain
related information required by the Company's By-laws, in writing to the
Secretary of the Company at the principal executive offices of the Company not
later than the close of business on the 90th day nor earlier than the close of
business on the 120th day prior to the first anniversary of the preceding year's
annual meeting. In the event, however, that the date of the annual meeting is
more than thirty days before or more than seventy days after that anniversary
date, the notice must be delivered not earlier than the close of business on the
120th day prior to such annual meeting and not later than the close of business
on the later of the 90th day prior to such annual meeting or the tenth day
following the day on which public announcement of the date of the meeting is
first made. Following verification of the stockholder's status, the
Compensation/Nomination/Governance Committee will perform an initial analysis of
the qualifications of the nominee pursuant to the criteria listed above to
determine whether the nominee is qualified for service on the Company's Board of
Directors before deciding to undertake a complete evaluation of the nominee.
Other than the verification of compliance with the procedures set forth in the
Company's By-laws and stockholder status, and the initial analysis performed by
the Compensation/Nomination/Governance Committee, a person nominated by a
stockholder for election to the Board of Directors is treated like any other
potential candidate during the review process by the
Compensation/Nomination/Governance Committee.

     COMMUNICATIONS WITH THE DIRECTORS.  Anyone who has a concern about the
Company's conduct, or about the Company's accounting, internal accounting
controls or auditing matters, may communicate that concern directly to the Board
of Directors, the Company's lead outside director (Mr. Stecko) or any other
non-employee director or the Audit Committee. All such concerns will be
forwarded to the appropriate directors for their review, and all concerns
related to audit or accounting matters will be forwarded to the Audit Committee.
All reported concerns will be simultaneously reviewed and addressed by the
Company's Chief Compliance Officer and General Counsel, or his designee (unless
he or she is alleged to be involved in the matter at issue). The status of all
outstanding concerns addressed to the Board, the non-employee directors or the
Audit Committee will be reported to the Board or the Audit Committee (as
applicable) on a quarterly basis. The Board or any committee may direct special
treatment, including the retention of outside advisors or counsel, for any
concern addressed to them. The Company's corporate policies prohibit retaliatory
action against any employee who raises concerns or questions in good faith about
these matters.

     Stockholders wishing to communicate with the Board of Directors, any
non-employee director or the Audit Committee may do so by writing to the
Company's Corporate Secretary at 500 North Field Drive, Lake Forest, Illinois
60045. The Corporate Secretary will forward any communications as directed by
the stockholder. The Company maintains a separate, internal system for the
receipt of communications from employees.
                                        12


COMPENSATION OF DIRECTORS

     FEE STRUCTURE.  In 2003, each Outside Director was paid an annual retainer
fee of $35,000 for service on the Board of Directors. In 2004, the annual
retainer fee will increase to $50,000. In general, 100% of the retainer fee is
to be paid in the form of common stock equivalents (the "directors' stock
equivalents"), as described below. A director may elect, however, to have up to
40%, or $14,000 in 2003 and $20,000 in 2004, of the fee paid in cash. The
Outside Directors also receive cash attendance fees, committee chair and
membership fees, and reimbursement of their expenses for attending meetings of
the Board of Directors and its committees. Outside Directors receive $1,000 for
each meeting of the Board of Directors attended. Beginning in 2004, Outside
Directors who are members of the Audit Committee and Compensation/Nominating/
Governance Committee will receive $1,000 for each in-person meeting, and $500
for each telephonic meeting, of the respective committee attended. In 2003, each
Outside Director who served as a Chairman of the Audit Committee or the
Compensation/Nominating/Governance Committee was paid a fee of $7,000 per
chairmanship. In 2004, the committee chair fee will increase to $8,000 per
chairmanship. Also, beginning in 2004, the lead outside director will be paid a
$6,000 retainer fee for serving as the chairman and primary spokesman when the
Board of Directors meets in executive session. Outside Directors who serve as
members of the Audit Committee or Compensation/Nomination/Governance Committee
are paid $4,000 per committee membership. Members of the Three-year Independent
Director Evaluation Committee receive $1,000 plus expenses for each meeting of
that committee attended.

     COMMON STOCK EQUIVALENTS/OPTIONS.  As described above, all or a portion of
an Outside Director's retainer fee is generally paid in common stock equivalent
units. These directors' stock equivalents are payable in cash or, at the
Company's option, shares of common stock after an Outside Director ceases to
serve as a director. Final distribution of these amounts may be made either in a
lump sum or in installments over a period of years. The directors' stock
equivalents are issued at 100% of the fair market value on the date of the
grant.

     In addition, each Outside Director generally receives an annual grant of an
option to purchase up to 5,000 shares of common stock. Directors' options: (a)
are granted with per share exercise prices equal to 100% of the fair market
value of a share of common stock on the day the option is granted; (b) have
terms of ten years; and (c) generally, will fully vest six months from the grant
date. Once vested, the directors' options will be exercisable at any time during
the option term.

     DEFERRED COMPENSATION PLAN.  The Company has a voluntary deferred
compensation plan for Outside Directors. Under the plan, an Outside Director may
elect, prior to commencement of the next calendar year, to have some or all of
the cash portion, that is, up to 40%, or $14,000 for 2003 and $20,000 for 2004,
of his or her retainer fee and some or all of his or her meeting fees credited
to a deferred compensation account. The plan provides these directors with
various investment options. The investment options include stock equivalent
units of the Company's
                                        13


common stock, which may be paid out in either cash or, at the Company's option,
shares of common stock.

     RESTRICTED STOCK.  In partial satisfaction of residual obligations under
the discontinued retirement plan for directors, Ms. Eickhoff receives an annual
grant of $15,400 in value of restricted shares of the Company's common stock.
The restricted shares may not be sold, transferred, assigned, pledged or
otherwise encumbered and are subject to forfeiture if the director ceases to
serve on the Board prior to the expiration of the restricted period. This
restricted period ends upon Ms. Eickhoff's normal retirement from the Board,
unless she is disabled or dies, or the Compensation/Nominating/Governance
Committee of the Board, at its discretion, determines otherwise. During the
restricted period, Ms. Eickhoff will be entitled to vote the shares and receive
dividends.

TRANSACTIONS WITH MANAGEMENT AND OTHERS

     Prior to August 12, 2003, Mr. Frissora was indebted to the Company for
amounts incurred in connection with his 1999 relocation from Ohio to the
Company's headquarters in Lake Forest, Illinois. This loan was made prior to the
adoption of the prohibition on loans to directors and executive officers
included in the Sarbanes-Oxley Act of 2002. The terms of the loan provided for
no interest and that principal was only payable in full upon termination of his
employment prior to August 2003, except for a termination without cause or
following a change in control. In accordance with the terms of the loan, the
aggregate outstanding balance ($400,000) was forgiven on August 12, 2003 based
on Mr. Frissora's continued employment at that time. This amount was included in
Mr. Frissora's taxable compensation for 2003.

        Illinois, and was forgiven in August 2003 in accordance with its

(1) Represents award of stock equivalent units made at the beginning of 2003 and
    which vested at the end of 2003 based on continued employment and the
    achievement of performance goals for the year ended December 31, 2003. Stock
    equivalent units are payable in cash in an amount equal to the number of
    units earned times the value per share of the Company's common stock at the
    time of payment (as determined in accordance with the terms of the grant).
    The payout of stock equivalent units reflected above was based on Economic
    Value Added (EVA(R), a registered trademark of Stern Stewart & Co.)
    improvement against the prior year. EVA is generally defined as operating
    profit minus the annual cost of capital. The number of stock equivalent
    units listed in this column represents the

                                        20


    target number of units that may be earned under the award. Prior to 2003,
    the Company's stock equivalent units, in general, have covered a three-year
    performance period, with partial settlement at the end of each year based on
    EVA performance. The performance period for the prior three-year grants
    ended December 31, 2002. The Compensation/ Nominating/Governance Committee
    granted the one-year awards reflected above for 2003 only and, beginning in
    2004, the Committee intends for the Company's stock equivalent unit program
    to again generally cover three-year performance periods.

(2) Represents the percentage of the units reflected in the first column of this
    table that may be earned based on the achievement of the performance goals
    at the threshold, target and maximum levels.

PENSION PLAN TABLE

     The following table shows the aggregate estimated total annual benefits
payable upon normal retirement pursuant to the Tenneco Retirement Plan, the
Tenneco Automotive Inc. Supplemental Executive Retirement Plan and the Tenneco
Automotive Retirement Plan for Salaried Employees to persons in specified
remuneration and years of credited participation classifications. In connection
with the Spin-Off, Pactiv Corporation became the sponsor of the Tenneco
Retirement Plan. The Company adopted a salaried defined benefit pension plan
patterned after the Tenneco Retirement Plan. The plan counts service prior to
the Spin-Off for all purposes, including benefit accrual, but there will be an
offset for benefits accrued under the Tenneco Retirement Plan. Therefore, as to
the Company's continuing employees, the benefits described in the table will be
provided by a combination of payments from the Tenneco Retirement Plan and the
new plan. The Company also maintains a key executive pension plan covering
executive officers, which will provide benefits, commencing at age 55, of 4% of
compensation (salary and bonus) per year of service up to a maximum of 50%,
reduced by payments under all other company sponsored qualified and nonqualified
defined benefit pension plans.

NOTES:

1. The benefits shown above are computed as a straight life annuity and are
   based on years of credited participation and the employee's average
   compensation, which is comprised of salary and bonus. These benefits are not
   subject to any deduction for Social Security or other offset amounts. As of
   December 31, 2003, the credited participation for Messrs. Frissora,

                                        22


   Donovan, Nair, Schneider and Bauer was 6 years/9 months, 3 years/5 months, 15
   years/ 9 months, 8 years/5 months and 6 years/4 months, respectively. See the
   Summary Compensation Table above for salary and bonus information for these
   individuals.

2. If Mr. Frissora completes 10 years of service in the period commencing
   January 1, 1999, he will be entitled to benefits commencing at age 55 of at
   least 40% of his average salary plus bonus determined over a three-year
   period.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

     The Company maintains a key executive change-in-control severance benefit
plan. The purpose of the plan is to enable the Company to continue to attract,
retain and motivate highly qualified employees by eliminating, to the maximum
practicable extent, any concern on the part of such employees that their job
security or benefit entitlements will be jeopardized by a "change-in-control" of
the Company, as that term is defined in the plan. The plan is designed to
achieve this purpose through the provision of severance benefits for key
employees and officers whose positions are terminated following a
change-in-control as provided in the plan. Under the plan, a severed executive
would receive a cash payment equal to three or two times, depending on his
grouping under the plan, (1) his or her base salary plus, (2) the higher of (a)
his or her average bonuses for the prior three years (or such shorter period as
the executive had been employed by the Company) and (b) his or her targeted
annual bonus in effect immediately prior to the change in control. The Company
expects that Messrs. Frissora, Donovan, Nair, Schneider and Bauer would have
become entitled to receive payments from the Company in the amount of
$4,340,250, $2,087,947, $1,912,575, $1,621,983 and $932,822, respectively, had
their positions been terminated on December 31, 2003 following a
change-in-control. In addition, restricted shares held in the name of those
individuals under restricted stock plans would have automatically reverted to
the Company, and the Company would have been obliged to pay those individuals
the fair market value of those restricted shares. Their stock equivalent units
would also have been fully vested and paid and their stock options would have
been fully vested.

     Each of the Named Executives, other than Mr. Bauer, is a party to an
agreement with the Company which sets forth certain terms and conditions of his
employment with the Company. Each of the employment agreements provides that,
under the Company's change-in-control severance benefit plan, the relevant Named
Executive's cash payment in connection with a change-in-control termination will
equal three times the total of his then current base salary plus the higher of
(i) his highest annual target bonus over the prior three years and (ii) his
average bonuses for the prior three years (or if shorter, his period of service
to the Company). Each of the employment agreements also provides that, other
than in connection with a change-in-control, if the relevant Named Executive's
employment is terminated by the Company other than for death, disability or
nonperformance of duties, he will be paid two times the total of his then

                                        23


current salary and bonus for the immediately preceding year, all outstanding
stock-based awards would be vested, subject to Board approval, and his stock
options would remain exercisable for at least 90 days. Pursuant to the terms of
their employment agreements, certain of the Named Executives are guaranteed a
minimum annual base salary/minimum annual target bonus as follows: Mr. Frissora,
$640,000/$590,000; Mr. Donovan, $301,600/$155,000; Mr. Nair, $305,000/$273,000;
and Mr. Schneider, $327,600/$155,000.

           TENNECO AUTOMOTIVE INC. COMPENSATION/NOMINATING/GOVERNANCE
                   COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The executive compensation philosophy, policies, plans and programs of the
Company are under the supervision of the Compensation/Nominating/Governance
Committee (the "Committee"), which is composed of the directors named below, all
of whom are independent for purposes of the rules of the NYSE. The Committee
operates under a written charter which is attached to this Proxy Statement as
Appendix B. The Committee has furnished the following report on executive
compensation:

COMPENSATION PHILOSOPHY

     The basic philosophy underlying the Company's executive compensation
policies, plans and programs is that executive and stockholder financial
interests should be aligned as closely as possible, and the compensation package
should be based on delivering pay in line with performance.

     Accordingly, the executive compensation program for the Company's Chief
Executive Officer ("CEO") and the other Named Executives, as well as other
executives of the Company, has been structured to:

     -- Reinforce a results-oriented management culture with executive pay that
        varies according to overall corporate and individual performance against
        operational and organizational goals.

     -- Focus executives on annual and long-term business results with the
        overarching goal of enhancing stockholder value.

     -- Align the interests of the Company's executives and stockholders through
        equity-based compensation awards.

     -- Provide executive compensation packages that attract, retain, and
        motivate executives of the highest qualifications and ability.

                                        24


     Based on these objectives, the executive compensation program has been
designed to promote appropriate levels of compensation derived from several
sources: salaries; annual cash incentive awards; stock ownership opportunities;
and other benefits typically offered to executives by major corporations.

     The Company's policy is to provide total compensation to its executives
based on performance that is competitive and at market levels, for comparable
companies, when financial and qualitative targets are met. In determining
competitive compensation for each of the components of executive compensation
described below, the Committee engages a nationally recognized, independent
compensation consulting firm which reports directly to the Committee.

     In making its determinations, the Committee generally reviews data
regarding compensation practices at other companies that it determines to be
relevant to compensation matters affecting the Company. Historically, this
information has included data regarding companies believed to be comparable to
the Company in terms of industry (i.e., automotive parts manufacturing), total
revenues, number of employees, capitalization or other factors. This year, the
Committee examined specific data regarding a comparison group comprised of 23
manufacturing and service companies -- including many automotive parts
manufacturers -- selected based on their similarity to the Company in terms of
size of revenues, total debt and market capitalization. The specific comparison
group was selected based on survey data regarding over 350 companies reviewed
and reported to the Committee by the independent compensation consulting firm.
The companies selected for compensation survey purposes are not identical to the
automotive industry peer group shown in the stock Performance Graph appearing
elsewhere in this Proxy Statement. The Committee does not limit its review for
compensation purposes to the automotive peer group companies because it believes
that individual employment determinations are often driven by factors beyond
those that are solely industry-specific.

     Salary levels are structured based upon reputable survey data for the
comparable companies. The Company's compensation plans provide that as an
executive's level of responsibility increases, (i) a greater portion of his/her
potential total compensation is based on performance (both individual and
corporate), and a lesser portion is comprised of salary, causing greater
potential variability in the individual's total compensation from year-to-year,
and (ii) the mix of compensation for that executive shifts to a greater portion
being derived from compensation plans where the executive's compensation level
varies in accordance with the market price of the Company's common stock.

     In designing and administering the components of the executive compensation
program, the Committee strives to balance short- and long-term incentive
objectives and to employ prudent judgment when establishing performance
criteria, evaluating performance and determining actual incentive payments.

                                        25


     Total executive compensation has two major components: (1) annual cash
compensation comprised of salary and bonus; and (2) long-term and stock-based
incentives comprised of some combination of stock options, performance-based
shares or share equivalents and restricted stock. The following is a description
of each of the components of the executive compensation program, along with a
discussion of the decisions of and action taken by the Committee with regard to
2003 compensation. There also follows a discussion regarding CEO compensation.

SALARY AND BONUS COMPENSATION

     An executive's annual cash compensation consists primarily of a base salary
plus amounts paid in lieu of Company matching contributions to the Company's
401(k) plans (when Internal Revenue Service maximums are reached) and bonuses
under the Company's executive incentive compensation plan, the Tenneco
Automotive Value Added Incentive Compensation Plan ("TAVA Plan"). Each year, the
Committee reviews with the CEO and the senior human resources executive of the
Company an annual salary and bonus target plan for the Company's executives and
other key management personnel (excluding the CEO), following which the
Committee approves that plan with changes that the Committee deems appropriate.
The salary and bonus target plan that is developed is based on competitive
market data and on assessments of past and anticipated future performance. The
Committee employs competitive market data for directional and guideline purposes
in combination with corporate, divisional and individual performance results.
The Committee also reviews (with the assistance of the senior human resources
executive and the nationally recognized, independent compensation consultant
engaged by the Committee) and sets the salary and bonus target of the CEO based
on similar information and criteria and the Committee's assessment of his past
performance with the Company and its expectations as to his future contribution
in leading the Company. For 2003, the Committee, at management's recommendation,
established a policy that there would be no increases in 2003 executive salaries
over 2002 based on the perceived challenges facing the Company in 2003. The 2002
salary levels established for the Company's executives had been designed to be,
in general, in the 50th percentile range when compared to the salaries set by
the companies in the compensation surveys reviewed by the Committee as described
above and remained in that 50th percentile range after applying the Committee's
policy of no increases for 2003. The target bonus levels established for the
Company's executives for 2003 were also designed to be, in general, in the 50th
percentile range when compared to target bonus levels set by the companies in
the compensation surveys reviewed by the Committee.

     Annual performance goals are established under the TAVA Plan at the
beginning of each year for purposes of determining incentive awards for that
year. The performance goals are generally developed, initially, by an
independent consulting firm with expertise in incentive programs. The firm's
recommended performance goals, after being reviewed by senior management, are
reviewed and approved by the Committee, with such changes as the Committee

                                        26


determines appropriate. At the conclusion of each year, the Committee approves
incentive award payments to executives based on the degree of achievement of the
goals established at the beginning of that year and on judgments of individual
performance as follows: (i) 75% of an individual's bonus is tied to the
Company's achievement of EVA(R)(1) objectives, and (ii) 25% of an individual's
bonus is based on judgmental considerations.

     The portion of an individual's bonus under the TAVA Plan that is tied to
EVA performance is calculated as follows: Each year, the individual's reserve
account under the TAVA Plan -- also known as the "bonus bank" -- is credited
with a bonus accrual (the "EVA-based bonus") equal to 75% of his or her total
bonus target (the "EVA-based target") multiplied by a Company performance factor
that is based upon the amount of improvement or deterioration in EVA. If the
annual EVA improvement is in excess of the targeted EVA improvement, the Company
performance factor will be a positive number in excess of one. If the annual EVA
improvement is less than the targeted EVA improvement, the Company performance
factor will be a number that is less than one or even less than zero. Because of
this, the EVA-based bonus for any year may be a positive or negative number. For
any year, an individual's payout is equal to the sum of: (i) his or her
EVA-based bonus for that year, if positive (but not exceeding 120% of his or her
EVA-based target), plus (ii) one-third of the individual's remaining bonus bank
as of the end of that year, if any. The value of an individual's bonus bank
reserve account may be positive or negative. The bonus bank functions to ensure
that any extraordinary EVA improvements are sustained before extraordinary bonus
awards are paid out. In addition, negative bonus bank balances are carried
forward to offset future bonuses to enhance accountability for sustained
positive performance over the long-term. Except for certain circumstances, such
as disability, any bonus bank is forfeited when an individual terminates
employment with the Company.

     The portion of an individual's bonus that is discretionary under the TAVA
Plan (25%) is determined by the Committee based on factors which take into
account the relative performance of the Company versus its peers in key areas
such as improvements in working capital and SGA&E (selling, general and
administrative expenses) as a percentage of sales, technology leadership,
improvements in EBITDA (earnings before interest, income taxes, depreciation and
amortization) margins, performance of the Company's stock, management retention
goals, overall market and industry conditions, the degree of difficulty in
meeting targets, contribution to overall corporate performance, including
efforts to deleverage the Company's balance sheet, environmental and safety
performance, quality initiatives and equal employment and diversity performance.

     For 2003, payouts under the TAVA Plan were, on average, made at 127.5% of
the aggregate targeted bonus amount for each executive. As described above, the
Company's performance

---------------
(1) EVA is after-tax operating profit minus the annual cost of capital. EVA is a
    registered trademark of Stern Stewart & Co.

                                        27


against its EVA objectives accounted for 75% of each executive's bonus. The
Company achieved performance goals commensurate with 191% payout of this portion
of executives' bonuses based on its 2003 EVA objectives. Based on this
performance level, under the TAVA Plan, only 120% of the executives' 2003
EVA-based target bonuses were eligible for payout for 2003. An amount equal to
71% (191%-120%) of the executives' 2003 EVA-based target bonuses was credited to
the bonus bank, with 1/3 of each executive's aggregate remaining bonus bank
(after giving effect to the 120% payout) eligible for payout for 2003. Payout of
the remaining 25% of each executive's bonus amount is discretionary and was
established by the Committee based on the various subjective factors described
above. Weighing these factors, the Committee determined that the 25%
discretionary portion of each executive's bonus would be paid, on average, at
75% of the targeted bonus amount. After giving effect to the 2003 payouts, an
aggregate of $2.2 million remained credited to the bonus bank under the TAVA
Plan.

     In making its determinations, the Committee noted in particular that the
Company's stock price had improved approximately 62% during 2003, from a closing
price of $4.13 on January 2, 2003 to $6.69 on December 31, 2003, and by an
additional 28% to $8.54 on January 17, 2004 (the last business day before the
Committee made its determinations). The Committee also noted the Company's
significant operational achievements for 2003, including achieving the highest
level of operating income since becoming a stand-alone company ($176 million),
reducing net debt by $105 million from the end of 2002 to the end of 2003 and
being awarded significant new business. On the other hand, the Committee also
took into account that the Company's 2002 share value performance ranked Tenneco
Automotive first versus nine other companies in its industry peer group, whereas
its 2003 share value performance ranked the Company fourth among those peers.

LONG-TERM AND STOCK-BASED INCENTIVES

     The Company's long-term and stock-based incentive plans have been designed
to align a significant portion of executive compensation with stockholder
interests. The current plan -- the 2002 Long-Term Incentive Plan as amended in
2003 -- permits the granting of a variety of awards including stock options,
restricted stock, stock equivalent units and performance units. The Company's
former plans were structured similarly.

     These awards are based on an analysis of competitive levels of similar
awards and an assessment of individual performance. As an individual's level of
responsibility increases, a greater portion of variable performance-related
compensation will be in the form of long-term and stock-based awards.

     Each year, the Committee reviews outstanding long-term and stock based
awards for the Company's executives, typically at its meeting held in January.
Based on this review, the Committee determines whether and to what extent to
make additional awards for the ensuing year. For 2003, the Committee implemented
a long-term and stock-based compensation

                                        28


program for the Company's executives that is comprised of (1) stock options
which generally vest in 1/3 increments over three years, (2) awards of
restricted stock which vest at the end of five years, subject to early vesting
after three years based on the achievement of EVA targets for the three-year
period, and (3) cash-settled stock equivalent units which are payable at the end
of 2003 based on the achievement of EVA targets. For 2003, the Company
discontinued its policy of awarding stock-settled performance units that were
payable at the end of three years based on the achievement of EVA targets. For
2004, the Committee intends to discontinue its policy of awarding five-year
restricted stock with an early vesting feature that is EVA-based and to replace
this component of the Company's long-term compensation with restricted stock
that vests after three years. Beginning in 2004, the Committee also intends to
include stock price appreciation, in addition to EVA results, as a performance
condition applicable to the stock equivalent units (as described below) and to
return to its prior practice of having the stock equivalent units generally
cover three-year periods with partial annual settlement.

     Beginning in 2003, the Committee has granted long-term awards to the
Company's executives that were designed to place them in the 50th percentile
range when compared to the value of similar awards granted by peer companies to
their executives.

     At the beginning of 2003, the Committee made awards to the Company's
executives that included options, restricted stock and cash-settled stock
equivalent units as described above. The Committee made its determinations
consistent with the philosophy described above, specifically noting the amount
of outstanding stock option, stock equivalent unit, performance unit and
restricted stock awards that had been granted to Company executives and the fact
that most of the prior awards made to the executives had fully vested at the end
of 2002. In making its award determinations, the Committee also noted in
particular the achievements made by the Company during 2002, including that,
despite continuing difficult market conditions, the Company had substantially
outperformed its internal plan for 2002 with respect to cash flows, working
capital improvements and various profitability measures.

     For 2003, the annually scheduled cash payout under the stock equivalent
unit awards described above was made in early 2004. Based on the Company's
achievement of EVA targets established for 2003, award holders earned 150% of
their targeted number of units for 2003, which is the maximum number of units
that could be earned for the year. The cash payouts were equal to the number of
units earned multiplied by the average of the closing prices of the Company's
common stock for the ten trading days immediately following the Company's public
announcement of its results of operations for 2003 ($10.79). Because the payouts
were based on this formula, final 2003 payouts benefited significantly from the
substantial appreciation in the Company's common stock price since the beginning
of 2003. As described above, beginning in 2004 the Committee intends to add
stock price appreciation as an additional performance criteria applicable to the
stock equivalent units. The Committee believes this will serve to further

                                        29


align executive and stockholder interests by ensuring that, prior to payout,
internal operational achievement must also be reflected in the Company's market
value.

CEO COMPENSATION

     For 2003, Mr. Frissora's base salary and bonus target were set at $730,000
and $610,000, respectively, to reflect his leadership of Tenneco Automotive in
implementing and sustaining various restructuring plans, process improvement
programs and other strategic initiatives in a continuingly difficult economic
and automotive industry environment. His 2003 base salary was the same as his
2002 base salary, reflecting a general Committee policy that there would be no
increases for Company executives in 2003. For 2003, the Committee approved the
payment of $777,750 to Mr. Frissora as his 2003 incentive award under the TAVA
Plan. This amount was based on a (1) a declared 2003 award of $873,825 under the
EVA-based portion of the TAVA Plan, of which, by the terms of the plan, $549,000
was automatically paid to Mr. Frissora and $324,825 was credited to his bonus
bank, (2) payment of 1/3 of Mr. Frissora's aggregate bonus bank, or $114,375,
and (3) payment of $114,375 under the discretionary portion of the TAVA Plan.
The amount of Mr. Frissora's incentive award was based on the same factors as
described above with respect to the 2003 bonuses paid to the Company's other
executives, including his overall leadership in driving the Company to the
performance improvements described above under "-- Salary and Bonus
Compensation." In addition, the Committee noted Mr. Frissora's strong individual
performance against his personal objectives in areas such as achieving improved
performance through continued implementation of the Company's Project Genesis
program. This program continues to significantly improve the manufacturing and
distribution footprint of the Company's operations. After giving effect to this
payment, $228,750 remained credited to Mr. Frissora's bonus bank under the TAVA
Plan. Mr. Frissora's 2003 base salary and bonus target were slightly below the
50th percentile of base salaries and target bonuses set for chief executive
officers of the comparable companies surveyed. In January 2003, in recognition
of the Company's substantial operational improvements for 2002 (as described
above under "-- Long-Term and Stock-Based Incentives") and a desire to provide
incentives for further achievements, the Committee awarded stock options,
restricted stock and stock equivalent units to Mr. Frissora as reflected under
"Executive Compensation." In addition, his stock equivalent unit award was paid
for 2003 at the earned level as described above for the Company's other
executives.

TAX LIMITATIONS ON THE DEDUCTIBILITY OF EXECUTIVE COMPENSATION

     Section 162(m) of the Internal Revenue Code of 1986, as amended, imposes a
$1 million limit on the amount that a publicly traded corporation may deduct for
compensation paid to the CEO or a Named Executive who is employed on the last
day of the year; provided, however, non-discretionary "performance based
compensation" is excluded from this $1 million limitation.

                                        30


     The Committee has reviewed section 162(m) and its related regulations and
feels that the Company's current compensation program and policies are
appropriate. The Committee structures the Company's compensation programs to
support organizational goals and priorities and stockholder interests. The
Committee seeks to preserve the tax deductibility of executive compensation to
the extent practicable and consistent with this philosophy. Because the
Committee retains certain discretion under the executive incentive program to
account for individual performance in making bonus awards, amounts payable to
the designated officers under the program may not be fully deductible where the
section 162(m) $1 million deduction limitation is otherwise reached. The
Committee believes this ability to exercise discretion, considered with the fact
that the 2003 salary and bonus paid to the Company's most highly compensated
executive only slightly exceeded $1 million, is in the best interests of the
Company and its stockholders. The stock equivalent unit, performance unit and
stock option awards made under the Company's long-term incentive plans, however,
are generally designed to incorporate the applicable requirements for
"performance-based compensation" for purposes of section 162(m).

                               PERFORMANCE GRAPH

     The performance graph presented below provides the cumulative total
stockholder return for Tenneco Automotive Inc. after the Spin-Off of Pactiv
Corporation, reflecting continuing operations. The Spin-Off of Pactiv
Corporation changed the Company in terms of revenue size and market
capitalization, and also represented the final step in the Company's transition
from a diversified holding company to a product- and market-focused company in
the automotive parts industry. The performance graph compares the cumulative
total stockholder return on the Company's common stock from November 5, 1999
(the first trading day after the Spin-Off) through December 31, 2003 with the
Standard & Poor's 500 Stock Index and a peer group of companies chosen by the
Company (the "Peer Group"). The companies comprising the Peer Group represent
other participants in the automotive industry. The performance graph assumes an
investment of $100 in each of the Company's common stock, the Standard & Poor's
500 Stock Index and the Peer Group index at the beginning of the period
described. The performance graph is not intended to be indicative of future
stock performance.

                           REPORT OF AUDIT COMMITTEE

GENERAL

     The Audit Committee comprises four directors and operates under a written
charter for the Audit Committee which is attached to this Proxy Statement as
Appendix A. All of the members of the Audit Committee meet the definition of
independent for purposes of the revised NYSE listing standards. In addition, the
Board has determined that Mr. Cramb qualifies as an "audit committee financial
expert" under the applicable SEC rules and all of the members of Audit Committee
satisfy the NYSE's financial literacy requirements.

REPORT

     The Audit Committee has furnished the following report:

     The Audit Committee has reviewed and discussed the audited financial
statements of the Company for the fiscal year ended December 31, 2003 with the
Company's management. In addition, the Audit Committee has discussed with
Deloitte & Touche LLP, the Company's independent auditors ("Deloitte & Touche"),
the matters required to be discussed by Statement on Auditing Standards No. 61,
"Communications with Audit Committees," and Regulation S-X Rule 2-07,
"Communication with Audit Committees."

     The Audit Committee has also received the written disclosures and the
letter from Deloitte & Touche required by Independence Standards Board Standard
No. 1, "Independence Discussions with Audit Committees," and has discussed with
Deloitte & Touche its independence from the Company and its management.

     The Audit Committee has considered whether the services rendered by the
Company's independent public accountants with respect to audit, audit-related,
tax and other non-audit fees are compatible with maintaining their independence.

     Based on the review and discussions referred to above, the Audit Committee
recommended to the Board of Directors that the audited financial statements for
the Company for the fiscal year ended December 31, 2003 be included in the
Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2003
for filing with the SEC.

              RATIFY APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS
                                    (ITEM 2)

       THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THIS PROPOSAL.

     Financial statements of the Company and its consolidated subsidiaries will
be included in the Company's Annual Report furnished to all stockholders. The
Audit Committee of the Board of Directors has appointed Deloitte & Touche LLP as
independent public accountants for the Company to examine its consolidated
financial statements for the year ending December 31, 2004, and has determined
that it would be desirable to request that the stockholders ratify the
appointment. You may vote for, vote against or abstain from voting with respect
to this proposal. Assuming the presence of a quorum, the affirmative vote of a
majority of the shares present, in person or by proxy, at the Annual Meeting and
entitled to vote is required to ratify the appointment. If the stockholders do
not ratify the appointment, the Audit Committee will reconsider the appointment.
Deloitte & Touche LLP was engaged as the Company's principal independent public
accountants for the years ended December 31, 2003 and 2002. Representatives of
Deloitte & Touche LLP are expected to be present at the Annual Meeting and will
have the opportunity to make a statement if they desire to do so and are also
expected to be available to respond to appropriate questions.

CHANGE IN INDEPENDENT PUBLIC ACCOUNTANTS IN 2002

     As previously reported by the Company in a Form 8-K dated May 16, 2002, the
Board of Directors, upon the recommendation of the Audit Committee, approved the
engagement of Deloitte & Touche LLP as the Company's independent auditors for
2002 effective May 16, 2002, replacing Arthur Andersen LLP (which was dismissed
as independent auditors of the Company effective May 16, 2002 and which
subsequently ceased accounting practice). Arthur Andersen LLP's reports on the
Company's financial statements for the prior two fiscal years ended December 31,
2001 did not contain an adverse opinion or a disclaimer of opinion and were not
qualified or modified as to uncertainty, audit scope or accounting principles.
During each of the prior two fiscal years ended December 31, 2001, and during
the interim period of 2002 for which Arthur Andersen continued to be engaged by
the Company, there were no disagreements with Arthur Andersen LLP on any matters
of accounting principles or practices, financial statement disclosure or
auditing scope and procedures which, if not resolved to the satisfaction of
Arthur Andersen LLP, would have caused Arthur Andersen to make reference to the
matter in their report. During 2002, the Company requested Arthur Andersen LLP
to furnish it a letter addressed to the SEC stating whether it agreed with the
above statements. A copy of that letter, dated May 17, 2002, was received and
filed as Exhibit 16.1 to the Company's Form 8-K dated May 16, 2002.

AUDIT, AUDIT-RELATED, TAX AND OTHER FEES

     The following table summarizes the aggregate fees billed to the Company for
the fiscal years ended December 31, 2003 and 2002 by the Company's principal

---------------

(a)  Fees for audit services in 2003 and 2002 consisted of:

     - Audit of the Company's annual financial statements including audits of
       subsidiary financial statements required by local country laws

     - Reviews of the Company's quarterly financial statements

     - Comfort letters, consents and other services related to SEC matters

(b)  Fees for audit-related services in 2003 and 2002 consisted of:

     - Sarbanes-Oxley Act, Section 404 advisory services

     - Employee benefit plan audits

(c)  Tax compliance services are services rendered based upon facts already in
     existence or transactions that have already occurred to document, compute,
     support and obtain government approval for amounts to be included in tax
     filings. Fees for tax compliance services in 2003 and 2002 consisted of:

     - Federal, state and local income tax return assistance

     - Sales and use, property and other tax return assistance

     - Transfer pricing documentation

     - Requests for technical advice from taxing authorities

     - Assistance with tax audits and appeals

                                        36


(d)  Tax planning and consulting services are services rendered with respect to
     proposed transactions or that alter a transaction to obtain a particular
     tax result. Fees for tax planning and consulting services in 2003 and 2002
     consisted of:

     - Tax advice related to intra-group transactions and restructurings

     - Tax planning related to certain foreign operations

(e)  Arthur Andersen LLP performed tax services from January 2002 through May
     2002, for which the Company paid Arthur Andersen LLP an additional
     $1,007,000.

     In considering the nature of the services provided by Deloitte & Touche,
the Audit Committee determined that such services are compatible with the
provision of independent audit services. The Audit Committee discussed these
services with Deloitte & Touche and Company management to determine that they
are permitted under the rules and regulations concerning auditor independence
promulgated by the SEC to implement the Sarbanes-Oxley Act of 2002, as well as
by the American Institute of Certified Public Accountants.

PRE-APPROVAL POLICY

     At a meeting held in September 2002, shortly after the adoption of the
Sarbanes-Oxley Act of 2002 and its provisions regarding audit committee
pre-approval of non-audit services provided by a public company's independent
public accountants, the Audit Committee approved the continued provision to the
Company of audit, audit-related and tax services as described above by Deloitte
& Touche. In March 2003, after the SEC's adoption of final rules regarding
provision of non-audit services by a public company's independent public
accountants, the Audit Committee adopted a pre-approval policy regarding these
services. All of the services performed by Deloitte & Touche in 2003 were
pre-approved in accordance with the pre-approval policy adopted by the Audit
Committee at its March 2003 meeting, which was revised and reauthorized at its
March 2004 meeting.

     The Audit Committee's pre-approval policy describes the permitted audit,
audit-related, tax and other services (collectively, the "Disclosure
Categories") that Deloitte & Touche may perform. The policy requires that, each
fiscal year, a description of the services (the "Service List") expected to be
performed by Deloitte & Touche in each of the Disclosure Categories, as well as
related budgeted fee amounts, be presented to the Audit Committee for approval.
Providing a range of fees for a service incorporates appropriate oversight and
control of the independent auditor relationship, while permitting the Company to
receive immediate assistance from the independent auditor when time is of the
essence.

     Any requests for audit, audit-related, tax and other services not included
on the Service List must be submitted to the Audit Committee for specific
pre-approval and cannot commence until such approval has been granted. Normally,
pre-approval is provided at regularly scheduled meetings. However, the authority
to grant specific pre-approval between meetings, as necessary,

                                        37


has been delegated to the Chairman of the Audit Committee. The Chairman must
update the Audit Committee at the next regularly scheduled meeting of any
services that were granted specific pre-approval. On a quarterly basis, the
Audit Committee reviews the status of services and fees incurred year-to-date
against the original Service List and the forecast of remaining services and
fees for the fiscal year. Any proposed service exceeding 120% of the
pre-approved cost level or budgeted amount requires specific additional
pre-approval by the Audit Committee.

                                 OTHER MATTERS

     The Board of Directors is not aware of any other matters that may properly
come before the Annual Meeting. However, should any such matters come before the
Annual Meeting, it is the intention of the persons named in the enclosed form of
Proxy card to vote all Proxies (unless otherwise directed by stockholders) in
accordance with their judgment on such matters.

                       SOLICITATION OF PROXIES AND VOTING

     Stockholders may specify their choices by marking the appropriate boxes on
the enclosed Proxy card. Alternatively, in lieu of returning signed Proxy cards,
stockholders can submit a Proxy over the Internet or by calling a specially
designated telephone number which appears on the Proxy cards. These Internet and
telephone voting procedures are designed to authenticate stockholders'
identities, allow stockholders to provide their voting instructions and confirm
the proper recording of those instructions. Specific instructions for
stockholders who wish to use the Internet or telephone voting procedures are set
forth on the enclosed Proxy card.

     All properly completed, unrevoked Proxies, which are received prior to the
close of voting at the Annual Meeting, will be voted in accordance with the
specifications made. If a properly executed, unrevoked written Proxy card does
not specifically direct the voting of shares covered, the Proxy will be voted
(i) FOR the election of all nominees for election as director described in this
Proxy Statement, (ii) FOR the ratification of the appointment of Deloitte &
Touche LLP, and (iii) in accordance with the judgment of the persons named in
the Proxy as to such other matters as may properly come before the Annual
Meeting.

     A Proxy may be revoked at any time prior to the voting at the Annual
Meeting by submitting a later-dated proxy (including a later-dated Proxy via the
Internet or telephone), giving timely written notice of such revocation to the
Secretary of the Company or by attending the Annual Meeting and voting in
person.

     The presence at the Annual Meeting, in person or by proxy, of holders of a
majority of the issued and outstanding shares of common stock as of the record
date is considered a quorum for the transaction of business. If you submit a
properly completed Proxy or if you appear at the Annual Meeting to vote in
person, your shares of common stock will be considered part of the

                                        38


quorum. Directions to withhold authority to vote for any director, abstentions
and broker non-votes (described below) will be counted to determine if a quorum
for the transaction of business is present. Once a quorum is present, voting on
specific proposals may proceed.

     The cost of solicitation of Proxies will be borne by the Company.
Solicitation will be made by mail, and may be made by directors, officers, and
employees, personally or by telephone, telecopy or telegram. Proxy cards and
material also will be distributed to beneficial owners of stock through brokers,
custodians, nominees and other like parties, and the Company expects to
reimburse such parties for their charges and expenses. Georgeson Shareholder
Communications Inc., New York, New York, has been retained to assist the Company
in the solicitation of proxies at a fee estimated not to exceed $25,000.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors and executive officers and beneficial owners of 10
percent or more of a registered class of the Company's equity securities
(collectively, "Reporting Persons") to file with the SEC initial reports of
beneficial ownership (Form 3) and reports on changes in beneficial ownership
(Form 4 or 5). SEC rules adopted pursuant to Section 16(a) require that
Reporting Persons furnish the Company with copies of all such forms they file
with the SEC.

     Based solely upon its review of such forms furnished to the Company during
2003, and upon the written representations received by the Company from certain
of the Company's directors and executive officers that no Forms 5 were required,
the Company has identified a non-timely filing during 2003 by David G. Gabriel,
a former officer of the Company, relating to an exercise of stock options by Mr.
Gabriel at the time of his departure from the Company. The Company believes that
no other Reporting Persons failed to file on a timely basis the reports required
by Section 16(a) of the Exchange Act during, or with respect to, 2003.

                   EFFECT OF ABSTENTIONS AND BROKER NON-VOTES

     Directions to withhold authority, abstentions and "broker non-votes" (which
occur when a nominee holding shares for a beneficial owner does not vote on a
proposal because the nominee does not have discretionary voting power with
respect to that item and has not received instructions from the beneficial
owner) will be counted in determining the presence or absence of a quorum for
the transaction of business at the Annual Meeting.

     Assuming the presence of a quorum, the affirmative vote of (1) a plurality
of the votes cast at the Annual Meeting (in person or by proxy) is required for
the election of directors, and (2) holders of a majority of the common stock
present at the Annual Meeting (in person or by

                                        39


proxy) and entitled to vote is required to ratify Deloitte & Touche LLP as the
Company's independent public accountants.

     Because the election of directors is determined on the basis of a plurality
of the votes cast, directions to withhold authority have no effect on the
election of directors. Because the vote standard for the approval of Deloitte &
Touche LLP is a majority of shares present and entitled to vote, abstentions
have the effect of a vote against and broker non-votes would have no effect on
the proposal.

                           INCORPORATION BY REFERENCE

     To the extent that this Proxy Statement is incorporated by reference in any
other filing by the Company under the Securities Act of 1933 or the Securities
Exchange Act of 1934, the information included or incorporated in the sections
of this Proxy Statement entitled "Executive Compensation -- Tenneco Automotive
Inc. Compensation/Nominating/Governance Committee Report on Executive
Compensation," "Performance Graph," and "Report of Audit Committee" will not be
deemed to be incorporated, unless specifically provided otherwise in such
filing.

                      SUBMISSION OF STOCKHOLDER PROPOSALS

STOCKHOLDER PROPOSALS -- INCLUSION IN COMPANY PROXY STATEMENT

     For a stockholder proposal to be considered by the Company for inclusion in
the Company's proxy statement and form of proxy relating to the annual meeting
of stockholders to be held in 2005, the proposal must be received by the Company
by December 1, 2004.

OTHER STOCKHOLDERS PROPOSALS -- DISCRETIONARY VOTING AUTHORITY AND BY-LAWS

     With respect to stockholder proposals not included in the Company's proxy
statement and form of proxy, the Company may utilize discretionary authority
conferred by proxy in voting on any such proposals if, among other situations,
the stockholder does not give timely notice of the matter to the Company by the
date determined under the Company's By-laws for the submission of business by
stockholders. This notice requirement and deadline are independent of the notice
requirement and deadline described above for a stockholder proposal to be
considered for inclusion in the Company's proxy statement. The Company's By-laws
state that, to be timely, notice and certain related information must be
received at the principal executive offices not later than the close of business
on the 90th day nor earlier than the close of business on the 120th day prior to
the first anniversary of the preceding year's annual meeting. However, in the
event that the date of the annual meeting is more than thirty days before or
more than seventy days after the anniversary date, the notice must be delivered
not earlier than the close of business on the 120th day prior to such annual
meeting and not later than the close of business on the later of the 90th day
prior to such annual meeting or the 10th day following the day on which public
announcement of the date of such meeting is first made. Therefore, to be timely
under the Company's By-laws, a proposal for the 2005 annual meeting not included
by or at the direction of the Board must be received not earlier than January
11, 2005, nor later than February 10, 2005.

                                                        AS ADOPTED MARCH 9, 2004

                         CHARTER OF THE AUDIT COMMITTEE
                           OF THE BOARD OF DIRECTORS
                           OF TENNECO AUTOMOTIVE INC.

     Tenneco Automotive Inc. recognizes that sound principles of corporate
governance and the integrity of the company's financial statements and financial
reporting processes are essential to obtaining and retaining the trust and
respect of investors and other persons and groups interested in the company and
its activities, including employees, customers, suppliers, communities in which
it does business, government officials and the public generally.

     The Board of Directors has approved the following Charter of the Audit
Committee that, together with the company's Corporate Governance Principles, is
intended to provide a framework for the governance of the company with respect
to the company's financial statements, financial reporting processes, systems of
internal controls and compliance with legal and regulatory requirements.

     I. Audit Committee Designation

          There is a committee of the Board of Directors of Tenneco Automotive
     Inc. called the Audit Committee.

     II. Audit Committee Purpose

          The Audit Committee is directly responsible for the appointment,
     compensation, retention and oversight of the work of the company's
     independent auditors. The purpose of the Audit Committee is to:

        - assist the Board of Directors in fulfilling its oversight of (a) the
          integrity of the company's financial statements and financial
          reporting processes and systems of internal controls regarding
          finance, accounting, information systems security, environmental
          compliance and legal compliance, (b) the company's compliance with
          legal and regulatory requirements, and (c) the independence,
          qualifications and performance of the company's independent auditors
          and internal auditing function;

        - provide an avenue of communication among the independent auditors,
          management, the internal auditors and the Board of Directors; and

        - prepare the audit-related report required by the Securities and
          Exchange Commission (SEC) to be included in the company's annual proxy
          statement.

                                       A-1


          The Audit Committee has the authority to conduct any investigation
     appropriate to fulfilling its responsibilities, and it has direct access to
     the independent auditors as well as any officer or other employee of the
     company or its subsidiaries. The Audit Committee has the ability to retain,
     at the company's expense, special legal, accounting or other consultants or
     experts it deems necessary in the performance of its duties.

     III.  Audit Committee Composition and Meetings

          The Audit Committee is comprised of three or more directors, as
     determined by the Board of Directors. The Board of Directors appoints the
     members of the Audit Committee annually, considering the recommendation of
     the Compensation/Nominating/Governance Committee, and further considering
     the views of the Chairman of the Board of Directors and the Chief Executive
     Officer, as appropriate. The members of the Audit Committee serve until
     their successors are appointed and qualify. The Board of Directors has the
     power at any time to change the membership of the Audit Committee and to
     fill vacancies in it, subject to the new member(s) satisfying the
     independence, experience and financial expertise requirements described in
     this Charter.

          Each member of the Audit Committee must be "independent" for purposes
     of Section 10A of the Securities Exchange Act of 1934, as amended, and the
     rules promulgated thereunder. Each member of Audit Committee must be an
     independent director as determined under the applicable rules of the New
     York Stock Exchange, and must also satisfy the additional New York Stock
     Exchange independence requirement for members of audit committees, in each
     case no later than the end of any applicable grace or "phase-in" period
     adopted by the New York Stock Exchange with respect to those rules.

          All members of the Audit Committee are required to have a basic
     understanding of finance and accounting and be able to read and understand
     fundamental financial statements. Unless otherwise determined by the Board
     of Directors to be appropriate under the circumstances, at least one member
     of the Audit Committee is required to be a "financial expert," and at least
     one member of the Audit Committee is required to have "financial
     expertise," as determined for purposes of the rules of the SEC and New York
     Stock Exchange, respectively.

          If an Audit Committee Chair is not designated by the Board of
     Directors or present, the members of the Audit Committee may designate a
     Chair by majority vote of the Audit Committee membership.

          The Audit Committee holds regular meetings, at least quarterly and
     additionally as often as the committee deems appropriate. The Audit
     Committee Chair approves an agenda in advance of each meeting. The Audit
     Committee should meet privately in executive session as often as it deems
     necessary, but at least annually, with management, the Internal Audit

                                       A-2


     Director, the independent auditors and as a committee to discuss any
     matters that the Audit Committee or any of these groups believe should be
     discussed.

          Except as expressly provided in this Charter, the by-laws of the
     company or any Corporate Governance Principles of the company, or as
     otherwise provided by law or the rules of the New York Stock Exchange, the
     Audit Committee may fix its own rules of procedure.

     IV. Audit Committee Responsibilities and Authority

          The Audit Committee has the sole authority to appoint or replace the
     independent auditors, and must approve all audit engagement fees and terms.
     The Audit Committee also must approve all non-audit engagements by the
     Company with the independent auditors, except as otherwise permitted by
     applicable law. The Audit Committee may consult with management but may not
     delegate these responsibilities, except that pre-approvals of non-audit
     services may be delegated to the extent permitted by applicable law. In its
     capacity as a committee of the Board, the Audit Committee is directly
     responsible for the oversight of the work of the independent auditors
     (including resolution of disagreements between management and the
     independent auditors regarding financial reporting) for the purpose of
     preparing or issuing an audit report or performing other audit, review or
     attest services for the Company, and the independent auditors report
     directly to the Audit Committee.

          In performing its functions, the Audit Committee undertakes those
     tasks and responsibilities that, in its judgment, would most effectively
     contribute to and implement the purposes of the Audit Committee. The
     following functions are some of the common recurring activities of the
     Audit Committee in carrying out its duties:

        Review Procedures

        1. The Audit Committee reviews and discusses with management and the
           independent auditors the company's annual audited financial
           statements and quarterly financial statements prior to filing or
           distribution, including the company's disclosures under "Management's
           Discussion and Analysis of Financial Condition and Results of
           Operations" and other matters required to be reviewed under
           applicable legal, regulatory or New York Stock Exchange requirements
           and, as appropriate, recommends to the Board of Directors whether the
           audited financial statements should be included in the company's Form
           10-K. The Audit Committee's review should include discussion with
           management and the independent auditors of significant issues
           regarding accounting principles, practices and judgments, including
           any items required to be communicated by the independent auditors in
           accordance with Statement on Auditing Standards No. 61.

                                       A-3


        2. The Audit Committee discusses with management and, as appropriate,
           the independent auditors earnings press releases (paying particular
           attention to any use of "pro forma" or "adjusted" non-GAAP
           information) and financial information and earnings guidance provided
           to analysts and ratings agencies.

        3. In consultation with the management, the independent auditors and the
           internal auditors, the Audit Committee considers the integrity of the
           company's financial reporting processes and controls.

        4. The Audit Committee reviews disclosures made by the company's
           principal executive officer or officers and principal financial
           officer or officers regarding compliance with their certification
           obligations as required under the Sarbanes-Oxley Act of 2002 and the
           rules promulgated thereunder, including the company's disclosure
           controls and procedures and internal controls for financial reporting
           and evaluations thereof.

        5. The Audit Committee reviews any reports of the independent auditors
           mandated pursuant to Section 10A of the Securities Exchange Act of
           1934, as amended, and the rules thereunder, and obtains from the
           independent auditors any information with respect to illegal acts in
           accordance with Section 10A and the rules thereunder.

        6. The Audit Committee reviews and discusses with management and the
           independent auditors, as applicable:

            a. major issues regarding accounting principles and financial
               statement presentations, including any significant changes in the
               company's selection or application of accounting principles, and
               major issues as to the adequacy of the company's internal
               controls and any special audit steps adopted in light of material
               control deficiencies;

            b. analyses prepared by management or the independent auditors that
               set forth significant financial reporting issues and judgments
               made in connection with the preparation of the financial
               statements, including analyses of the effects of alternative GAAP
               methods on the financial statements;

            c. any management letter provided by the independent auditors and
               the company's response to that letter;

            d. any problems, difficulties or differences encountered in the
               course of the audit work, including any disagreements with
               management or restrictions on the scope of the independent
               auditors' activities or on access to requested information and
               management's response thereto;

            e. liquidity, off-balance sheet structures and debt covenants; and

                                       A-4


            f. the effect of significant regulatory and accounting initiatives
               on the financial statements of the company.

        7. The Audit Committee discusses with management the company's major
           financial risk exposures and the steps management has taken to
           monitor and control those exposures, including the company's risk
           assessment and risk management policies.

        Independent Auditors

        8. The independent auditors are ultimately accountable to the Audit
           Committee. The Audit Committee reviews the independence,
           qualifications and performance of the auditors at least annually,
           including a review and evaluation of the lead partner of the
           independent auditors and taking into account the opinions of
           management and the company's internal auditors. At least annually,
           the Audit Committee appoints the company's independent auditors for
           the ensuing fiscal year, and will report to the Board of Directors
           regarding its determinations about the appointment or removal of any
           independent auditors.

        9. The Audit Committee obtains and reviews a report from the independent
           auditors at least annually regarding:

            a. the independent auditors' internal quality-control procedures;

            b. any material issues raised by the most recent quality-control
               review, or peer review, of the firm, or by any inquiry or
               investigation by governmental or professional authorities within
               the preceding five years respecting one or more independent
               audits carried out by the firm; and

            c. any steps taken to deal with any such issues.

        10. On an annual basis, the Audit Committee requires the independent
            auditors to submit a formal written statement delineating all
            relationships between the auditors and the company or its
            subsidiaries or affiliates, and reviews and discusses all
            significant relationships that could impair the auditors'
            independence. It is the responsibility of the Audit Committee to
            take appropriate action in response to the independent auditors'
            report to satisfy itself of the auditors' independence.

        11. At least annually, the Audit Committee reviews the independent
            auditors' audit plan with respect to the ensuing fiscal year, and
            discusses with them, as determined appropriate, the plan's scope,
            staffing, locations, reliance upon management and internal audit and
            general audit approach.

        12. It is the responsibility of the Audit Committee to ensure that the
            representatives of the independent auditors who perform work for the
            company are rotated as

                                       A-5


            required by the Sarbanes-Oxley Act of 2002 and other applicable law,
            and to further consider rotation of the independent auditor firm
            itself.

        13. The Audit Committee discusses with the independent auditors any
            communications between the audit team and the audit firm's national
            office regarding any material auditing or material accounting issues
            presented by the independent auditors' engagement by the company.

        14. The Audit Committee discusses with management and the independent
            auditors any accounting adjustments that were noted or proposed by
            the independent auditors but were not recorded by management
            (because they were deemed to be immaterial or otherwise were
            "passed").

        Internal Audit

        15. It is the responsibility of the Audit Committee to ensure that the
            company maintains an internal audit function.

        16. At least annually, the Audit Committee reviews the company's
            internal audit plan, activities, organizational structure and
            staffing. The Audit Committee reviews any significant changes to the
            company's internal audit plan.

        17. The Audit Committee reviews significant reports prepared by the
            internal audit department, together with management's response and
            follow-up to these reports.

        18. At least annually, the Audit Committee discusses with the
            independent auditors the company's internal auditors and their audit
            plan, responsibilities, budget and staffing.

        Environmental and Legal Compliance

        19. At least annually, the Audit Committee reviews with the company's
            General Counsel:

            a. any environmental or legal matters that could have a significant
               impact on the company's financial statements;

            b. compliance by the company and its subsidiaries with applicable
               laws and regulations; and

            c. any inquiries received from regulators or governmental agencies
               by the company or its subsidiaries.

                                       A-6


        Other Audit Committee Responsibilities

        20. It is the responsibility of the Audit Committee to annually prepare
            a report to stockholders as required by the rules of the SEC. The
            report is included in the company's annual proxy statement.

        21. It is the responsibility of the Audit Committee to review and
            reassess the adequacy of this Charter at least annually and to
            recommend any proposed changes to the Board of Directors for
            approval. It is the responsibility of the Audit Committee to cause
            the Charter to be published in accordance with applicable SEC and
            New York Stock Exchange regulations.

        22. The Audit Committee monitors compliance with the company's Statement
            of Business Principles.

        23. As may be set forth from time to time in the company's Statement of
            Business Principles (or other code of business conduct and ethics
            adopted by the company), the Audit Committee may be responsible for
            granting waivers of the Statement of Business Principles (or other
            code of business conduct and ethics) for directors and executive
            officers.

        24. Pursuant to applicable SEC rules, it is the responsibility of the
            Audit Committee to establish procedures for:

            a. the receipt, retention and treatment of complaints received by
               the company and its subsidiaries regarding accounting, internal
               accounting controls or auditing matters; and

            b. the confidential, anonymous submission by employees of the

               accounting or auditing matters.

        25. The Audit Committee shall from time to time establish policies for
            the company's hiring of employees or former employees of the
            independent auditors who were engaged on the company's account
            (recognizing that the hiring by the Company of certain
            representatives of the independent auditors could jeopardize the
            auditors' independence or otherwise be prohibited).

        26. It is the responsibility of the Audit Committee to maintain minutes
            of its meetings and report, through its Chair, to the Board of
            Directors on significant results of each meeting.

            self-assessment of its performance at least annually.

     V. Funding

          The Audit Committee shall be given the resources and assistance
     necessary, including adequate funding, as determined by the Audit
     Committee, for payment of the compensation of any registered public
     accounting firm engaged for the purpose of preparing or issuing an audit
     report or performing other audit, review or attest services for the company
     or any advisors employed by the Audit Committee, as well as for payment of
     ordinary administrative expenses of the Audit Committee that are necessary
     or appropriate in carrying out its duties.

     VI. Limitations on Audit Committee Responsibilities

          While the Audit Committee has the responsibilities and powers set
     forth in this Charter, it is not the duty of the Audit Committee to prepare
     financial statements, plan or conduct audits or to determine that the
     company's financial statements and disclosures are complete and accurate
     and are in accordance with generally accepted accounting principles and
     applicable rules and regulations. These are the responsibilities of
     management and the independent auditors. In carrying out its oversight
     responsibilities, the Audit Committee is not providing any expert,
     professional or special assurance as to the company's financial statements
     or any professional certification. Audit Committee members are not deemed
     to have accepted a duty of care greater than the duty of other directors.
     Nothing contained in this Charter is intended to alter the operation of the
     "business judgment rule" as interpreted under Delaware law.

          CHARTER OF THE COMPENSATION/NOMINATING/GOVERNANCE COMMITTEE
                           OF THE BOARD OF DIRECTORS
                           OF TENNECO AUTOMOTIVE INC.

     Tenneco Automotive Inc. recognizes that sound principles of corporate
governance are essential to obtaining and retaining the trust and respect of
investors and other persons and groups interested in the company and its
activities, including employees, customers, suppliers, communities in which it
does business, government officials and the public generally.

     The Board of Directors has approved the following Charter of the
Compensation/Nominating/Governance Committee that, together with the company's
Corporate Governance Principles, is intended to provide a framework for the
governance of the company with respect to the matters involving compensation,
director and executive officer selection and succession and general corporate
governance.

     I. Compensation/Nominating/Governance (CNG) Committee Designation

          There is a committee of the Board of Directors called the
     Compensation/Nominating/ Governance Committee.

     II. CNG Committee Purpose

          The purpose of the CNG Committee is to:

        - assist the Board of Directors in discharging the Board of Directors'
          responsibilities relating to compensation of the company's executives
          and other employees;

        - produce an annual report on executive compensation for inclusion in
          the company's proxy statement in accordance with applicable rules and
          regulations of the Securities and Exchange Commission;

        - identify individuals qualified to become Board of Directors members,
          recommend to the Board of Directors the slate of nominees to be
          recommended by the Board for election at applicable meetings of
          stockholders and recommend to the Board of Directors the composition
          of its several committees; and

        - develop and recommend to the Board of Directors, review and, as
          appropriate, from time to time recommend to the Board of Directors
          revisions to Corporate Governance Principles applicable to the
          company.

                                       B-1


     III. CNG Membership and Procedure

          The CNG Committee consists of at least three members, all of whom
     shall be "independent" as described below. The Board of Directors appoints
     the members of the CNG Committee annually, considering the recommendation
     of the CNG Committee, and further considering the views of the Chairman of
     the Board and the Chief Executive Officer, as appropriate. The members of
     the CNG Committee serve until their successors are appointed and qualify.
     The Board of Directors has the power at any time to change the membership
     of the CNG Committee and to fill vacancies in it, subject to such new
     member(s) satisfying the requirements described herein.

          Each member of the CNG Committee must be "independent" as determined
     under the applicable rules of the New York Stock Exchange (NYSE), no later
     than the end of any applicable grace or "phase-in" period adopted by the
     NYSE with respect to those rules. Further, if deemed appropriate from time
     to time, each member of the CNG Committee will be required to meet the
     definition of "non-employee director" under Rule 16b-3 under the Securities
     Exchange Act of 1934 and "outside director" for purposes of Section 162(m)
     of the Internal Revenue Code of 1986.

          If a CNG Committee Chair is not designated by the Board of Directors
     or present, the members of the CNG Committee may designate a Chair by
     majority vote of the CNG Committee membership.

          The CNG Committee holds regular meetings each year as often as the
     committee deems appropriate. The CNG Committee Chair approves an agenda in
     advance of each meeting.

          Except as expressly provided in this Charter, the by-laws of the
     company or the Corporate Governance Principles of the company, the CNG
     Committee may fix its own rules of procedure.

     IV. CNG Committee Authority and Responsibilities

          In performing its functions, the CNG Committee undertakes those tasks
     and responsibilities that, in its judgment, would most effectively
     contribute to and implement the purposes of the CNG Committee. The
     following functions are some of the common recurring activities of the CNG
     Committee in carrying out its duties:

        Compensation-Related

        1.  The CNG Committee reviews and approves corporate goals and
            objectives relevant to CEO compensation, evaluates the CEO's
            performance in light of those goals and objectives, and (either as a
            committee or together with the company's other

                                       B-2


            independent directors, as directed by the Board) determine and
            approve the CEO's compensation level based on this evaluation.

        2.  In determining the long-term incentive component of CEO
            compensation, the CNG Committee should, as it determines
            appropriate, consider the company's performance and relative
            stockholder return, the value of similar incentive awards to CEOs at
            comparable companies, and the awards given to the company's CEO in
            past years.

        3.  The CNG Committee establishes the salary rates and compensation
            structure for other executive officers of the company and its
            affiliated companies, subject to the right of the CNG Committee to
            delegate to the Chief Executive Officer the fixing of compensation
            below certain levels determined by the committee, and may
            periodically examine the compensation structure of the company and
            its affiliated companies for other employees.

        4.  The CNG Committee has, to the extent permitted by law and the
            applicable rules of the NYSE, the authority to administer,
            establish, terminate or amend and to otherwise act for and on behalf
            of the Board of Directors with respect to the employee benefit plans
            of the company and its affiliated companies, including both welfare
            and pension plans (hereinafter referred to as the "Benefit Plans"),
            including any supplemental Benefit Plans, severance plans of limited
            duration and any other similar plans which the CNG Committee deems
            desirable to establish, terminate or amend from time to time.

        5.  The CNG Committee has, to the extent permitted by law and the
            applicable rules of the NYSE, the authority to administer,
            establish, terminate or amend and to otherwise act for and on behalf
            of the Board of Directors with respect to executive and director
            compensation, incentive compensation, deferred compensation and
            stock option and restricted stock plans and programs of the company
            and its affiliated companies (hereinafter referred to as the
            "Compensation Plans"), including other similar compensation plans
            the CNG Committee deems desirable to establish, terminate or amend
            from time to time, such authority hereby granted to the CNG
            Committee to include, without limitation, the power and authority to
            authorize the issuance of stock pursuant to such Compensation Plans,
            in such manner as the CNG Committee will deem best for the interests
            of the company, in all cases in which specific directions have not
            been given by the Board.

        6.  The CNG Committee ensures that qualified firms are advising the
            company on compensation matters, managing diversity and related
            matters. The CNG Committee should meet privately in executive
            session as often as it deems necessary, but

                                       B-3


            at least annually, with any compensation or similar consultants to
            the company to discuss any matters that the CNG Committee or these
            consultants believe should be discussed. If a compensation
            consultant is engaged to assist in the evaluation of director, CEO
            or senior executive compensation, the CNG Committee has the sole
            authority to retain and terminate that consultant, including sole
            authority to approve its fees and other retention terms.

        7.  The CNG Committee reviews and approves the list of a peer group of
            companies to which the company compares itself for compensation
            purposes.

        Nominating/Governance-Related

        8.  Subject to the qualification requirements for the Board of Directors
            set forth in the company's Corporate Governance Principles, the CNG
            Committee is responsible for reviewing and proposing to the Board of
            Directors additional qualifications for directors as determined to
            be necessary or appropriate, taking into account the desirable
            balance of experience, qualifications and expertise among members of
            the Board of Directors.

        9.  The CNG Committee reviews possible candidates for membership on the
            Board, and assists in attracting qualified candidates to fill vacant
            or newly created directorships.

        10. It is the responsibility of the CNG Committee to review and
            recommend to the Board of Directors a management slate of directors
            to be proposed for election at the annual stockholders' meeting and
            included in the proxy statement for such meeting, as well as to
            review and recommend to the Board of Directors any directors to fill
            vacancies that may exist on the Board of Directors.

        11. It is the responsibility of the CNG Committee to review the function
            and composition of the several committees of the Board of Directors
            and to recommend to the Board of Directors qualified persons for
            membership on such committees.

        12. It is the responsibility of the CNG Committee to review the
            qualifications of candidates for election as officers of the company
            and to recommend those candidates for election by the Board of
            Directors at least annually.

        13. It is the responsibility of the CNG Committee to review annually the
            availability of qualified replacements for key executive positions
            in the company and its subsidiaries and the nature and adequacy of
            the company's plans for developing and providing necessary
            replacements both on a current and on a long-term basis, so as to
            ensure continuity and orderly succession of capable and qualified
            management for the company.

                                       B-4


        14. The CNG Committee oversees the evaluation of the executive
            management of the company and makes recommendations to the Board of
            Directors as it determines appropriate.

        15. The CNG Committee reviews and reassesses at least annually the
            adequacy of the Corporate Governance Principles of the company and
            recommends any proposed changes to the Board of Directors for
            approval.

        16. The CNG Committee serves in an advisory capacity to the Board of
            Directors and Chairman of the Board on matters of organizational and
            governance structure of the company and the conduct of the Board of
            Directors.

        17. The CNG Committee receives comments from all directors and, as
            directed by the Board of Directors, reports orally annually to the
            Board of Directors with an assessment of the Board of Director's
            performance, to be discussed with the full Board of Directors

            its meetings and report, through its Chair, to the Board of
            Directors on significant results of each meeting.

        19. The CNG Committee has the ability to retain, at the company's
            expense, special legal, accounting or other consultants or experts
            it deems necessary in the performance of its duties.

        20. It is the responsibility of the CNG Committee to review and reassess
            the adequacy of this Charter at least annually and to recommend any
            proposed changes to the Board of Directors for approval. It is the
            responsibility of the CNG Committee to cause the Charter to be
            published in accordance with applicable NYSE regulations.

        21. It is the responsibility of the CNG Committee to annually review its
            own performance.

        22. The CNG Committee may form and delegate authority to subcommittees
            when appropriate and to the extent permitted by applicable law and
            the rules of the NSYE.

        23. In performing its duties, the CNG Committee is not providing any
            expert, professional or special assurances as to the matters
