Mr. Roger J. Wood
[Address]

Dear Roger:

I am pleased to inform you that Tenneco Inc.’s (“Tenneco”) Board of Directors
has elected to offer you the position as the Chairman and Chief Executive
Officer of the future “Powertrain Technology” company (Tenneco Clean Air and
Federal-Mogul Powertrain), effective upon the successful completion of Tenneco’s
previously announced intention to separate into two independent publicly traded
companies (the “Spinoff”). In the interim, and to facilitate a smooth transition
through the Spinoff, we are also pleased to offer you employment in the position
of Co-Chief Executive Officer of Tenneco Inc., effective as of the date of the
closing of Tenneco’s acquisition of Federal-Mogul (the “Closing”).

The key terms of Tenneco’s offer of employment are described below.

Outline of Employment Offer

1.
Position: Your position with the future Powertrain Technology company, effective
upon the Spinoff, will be Chairman and Chief Executive Officer, reporting
directly to the Board of Directors of that company. In the interim, effective
upon the Closing, your position will be Co-Chief Executive Officer, reporting
directly to the Board of Directors of Tenneco Inc.

2.
Base Salary: Your initial base salary will be $1,050,000 per year ($87,500.00
per month) less appropriate taxes and withholding, paid in accordance with
Tenneco’s normal payroll practices. Beginning in 2019 and each year thereafter,
your base salary will be reviewed and, in turn, may be adjusted, subject to
approval by the Compensation Committee of Tenneco Inc.’s Board of Directors.

3.
Annual Incentive Compensation: You will be eligible to participate in Tenneco’s
executive annual incentive plan in a manner consistent with other Tenneco
executives. The terms of the annual incentive plan are set forth in the Tenneco
Inc. Annual Incentive Plan (“AIP” - copy attached). Your initial target bonus
opportunity for the 2018 calendar year performance period under the AIP will be
125% of your annual base salary (or $1,312,500 based on the offered salary,
pro-rated to the date that your employment commences with Tenneco) although the
actual value will be determined by the Compensation Committee. The payment of an
annual incentive to you is subject to achievement of pre-defined performance
goals for the Company, the approval by the Compensation Committee, as well as
the terms of the AIP (or successor plan).

4.
Long-Term Incentive Compensation: You will be eligible to participate in
Tenneco’s long-term incentive plan in a manner consistent with other Tenneco
executives. The terms of the long-term incentive plan are set forth in the
Tenneco Long-Term Incentive Plan, as amended (“LTIP”), a copy of which has been
attached.

Each year the Compensation Committee will determine and approve the mix of
long-term incentive (LTI) awards that will be granted to you and the aggregate
target value of these awards. Your first eligibility for a full LTI award will
be in February 2019. The final award size, award type, performance conditions
and other terms of this award will be approved by the Compensation Committee in
February 2019 at the same time the terms of these awards are established for
other executives at the Company. Your 2019 LTI award is currently estimated to
have a $5,400,000 value.

As part of the LTI award, you will also be eligible to receive a 2018 LTI award
equal to $5,400,000, prorated to your employment date, if you are employed
before December 1, 2018. Your 2018 LTI award will be granted as restricted stock
units (RSUs) with a 3-year ratable vesting.

For purposes of the LTIP (and accelerated vesting of awards thereunder),
“Retirement” will mean your termination of employment (other than for cause)
after you have (i) attained age 60 or (ii) attained age 55 and completed 10
years of service with the Tenneco and its affiliates. In each case, eligibility
for accelerated vesting of awards for Retirement shall not occur until after the
first anniversary of the Grant Date of the applicable award.

5.
Retirement Plans: You will be eligible to participate in Tenneco’s 401(k) Plan
that currently provides a 100% company match on your first 3%, and 50% of your
next 2%, of base pay contributions subject to Plan and IRS maximums. In
addition, you will annually receive a 2% of base pay contribution into the
401(k) Plan starting after one year of service, vesting on your third year of
service.

You will also be eligible to immediately participate in Tenneco’s Excess Benefit
Plan that will provide you with a benefit of a 3% of base pay company
contribution after IRS compensation maximums have been reached, and a company
contribution equal to 3% of AIP bonus paid.

6.
Change-In-Control (CIC) Protection: You will be eligible to participate in
Tenneco’s Change-In-Control Severance Benefit Plan for Key Executives. Benefits
under the Plan are payable if you are discharged (either actually or
constructively) within two years after a change-in-control that occurs after the
effective date of your employment. The plan generally provides a lump-sum
payment equal to three times base salary and targeted annual bonus in effect
immediately prior to the change-in-control.

7.
Severance (not related to CIC): If your employment is involuntarily terminated
by the company for reasons other than disability or Cause or if you terminate
your employment due to Constructive Termination and, in any case, other than
under circumstances which would entitle you to benefits under the Change in
Control Plan, you will be entitled to severance equal to two times the sum of
your annual base salary and target bonus for the year in which your termination
occurs, payable in a lump sum within 60 days of termination, subject to your
execution of a general release and such other documents as the company may
reasonably request. For these purposes (A) Cause means (i) fraud, embezzlement,
or theft in connection with your employment, (ii) gross negligence in the
performance of your duties, or (iii) conviction, guilty plea, or plea of nolo
contender with respect to a felony, and (II) Constructive Termination will have
the same meaning (and will be subject to the same terms required to effect a
Constructive Termination, such as notice and cure periods) as under the Change
in Control Plan, provided that for purposes of the foregoing benefits, the
comparison as to whether there has been an adverse event will be determined
immediately prior to and immediately after an action taken by the company
(rather than before and after a change in control) and the determination of
whether there has been a material breach by the company will be based on the
terms of this letter (rather than the Change in Control Plan).

8.
Stock Ownership Guidelines: Upon employment, you will be subject to Tenneco’s
stock ownership guideline policy, requiring that you hold qualifying shares of
Tenneco Inc. equal to six times base salary, to be attained by the first month
of January following five years of employment.

9.
Insider Trading Policy: Upon employment, you will be subject to Tenneco’s
Insider Trading Policy, which, among other things, limits the timing and types
of transactions you may make with respect to Tenneco securities and related
derivatives.

10.
Health, Welfare and Retirement Benefits: You will be eligible to participate in
Tenneco’s broad-based health, welfare and defined contribution retirement plans
in a manner consistent with other Tenneco executives. Please refer to benefit
plan documents for specific terms and eligibility. The Company reserves the
right to change these benefit programs and any of our other benefit programs.
Attached for your convenience is the Tenneco 2018 Benefits At A Glance for
Salaried Employees.

11.
Vacation and holiday paid time off: You will be entitled to a total of four
weeks of paid vacation per year: two weeks in accordance with the provisions of
the Company’s vacation policy and two additional negotiated weeks. Your vacation
accrual will thereafter increase only in accordance with the vacation schedule
in the policy (i.e., you will accrue five weeks of vacation upon reaching 20
years of service). In addition, the Company is typically closed during the week
between Christmas and New Year’s Day holidays. You will also be eligible for
paid holidays and personal floating holidays in accordance with the Company’s
policies. When you leave employment with Tenneco, you will receive a payment for
any vacation you have accrued and not used. Vacation is prorated to your date of
employment and accrued on a monthly basis.

are enclosed for your review. Use of a Company provided T&E credit card or any
relocation assignment related expenses is prohibited.

13.
Employment at Will: This offer does not constitute a contract of employment for
any specific period of time, but will create an employment at-will relationship
that may be terminated at any time by you or the Company, with or without cause.

In addition, your offer is contingent upon the verification of the information
you have provided to the company, successful completion of employment paperwork,
the completion of a Combined Disclosure Notice & Authorization Regarding
Background Consumer Reports and background authorization forms and execution of
the Tenneco Confidentiality Agreement (this will be part of your “on-boarding”
process).

On or before your first day of employment, you must provide documentation that
you have authorization to work in the United States. The offer is contingent
upon you providing appropriate I-9 documentation (see enclosed). Two copies of
this offer letter have been provided. Please sign the offer letter and return it
to me as soon as possible. The second copy should be retained for your personal
records.

Roger, we look forward to you joining Tenneco and are excited for you to
