Larry D. Yost
Troy, Michigan

Dear Larry:

We are pleased to extend to you our offer of employment for the position of
Chairman and Chief Executive Officer of ArvinMeritor, Inc., effective as of
the consummation of the merger between Arvin Industries and Meritor
Automotive, Inc. on July 7, 2000. Subject to the approval of the ArvinMeritor
Board of Directors, you will become an elected officer of ArvinMeritor,
effective July 7, 2000. In this position, you will report to the Board of
Directors of ArvinMeritor, Inc., and be based in Troy, Michigan.

You will continue to receive your current monthly base salary. As in the past,
your salary will be reviewed in November of each year for possible adjustment
based on performance.

Please note that this offer is subject to formal approval by the ArvinMeritor
Compensation Committee of the Board of Directors. Discussions have been held
with members of the Meritor Compensation Committee, and we are confident that
the ArvinMeritor Compensation Committee will approve our offer.

Annual Incentive Plans

As a prior Meritor employee, you will continue to participate in the Meritor
FY2000 ICP through September 30, 2000 with actual performance based on
continuing operations assessed against targeted goals, excluding the impact of
the merger with Arvin.

You will be eligible to participate in the ArvinMeritor annual incentive plan
beginning in FY2001. We fully anticipate the ArvinMeritor plan will mirror
Meritor's current plan.

Long-Term Incentives

Your outstanding stock options and/or restricted shares will be converted,
based upon the agreed upon conversion ratio, into ArvinMeritor options and/or
restricted shares.

You will continue to participate in Meritor's FY1998-2000, FY1999-2001 and
FY2000-2002 LTIP Cash Performance Plan cycles that are underway at your
current target cash award level.

In addition you will be eligible to participate in ArvinMeritor's Long-Term
Incentives Plan (LTIP) beginning with the FY2001 annual stock option grant and
LTIP Performance Plan award.

    Note: You will receive additional information about ArvinMeritor's annual
    incentive and long term incentive plans during the first quarter of
    FY2001, which are expected to be the same as the current Meritor plan.

Special Merger Award

You will receive a special "merger award" as a lump-sum cash payment, upon
consummation of the merger in the amount of $700,000. You will be expected to
invest (net of all associated taxes) up to 50% of this lump-sum payment in
ArvinMeritor stock on or before October 31, 2000. This is necessary only to
the extent needed to fully achieve ArvinMeritor's executive stock ownership
guidelines. Since the ArvinMeritor stock ownership guidelines mirror Meritor's
guidelines, your obligation under the stock ownership guidelines do not
change.

Benefits

You will be eligible, based upon your position/compensation level, for all the
regular ArvinMeritor health, welfare, retirement and other employee benefit
programs. We are currently in the process of developing a plan to consolidate
the Arvin and Meritor benefit programs and defining the ArvinMeritor benefit
package which will be substantially comparable in the aggregate to the Arvin
and Meritor benefit plans. The ArvinMeritor integration plans provide for the
creation of a single ArvinMeritor benefits structure to be effective January
1, 2001.

Through December 31, 2000, your employee benefits will remain in effect as
they were before the merger. You will continue to participate in various
benefit plans formerly sponsored by Meritor.

The only change that you will experience is that, if you participate in the
Savings Plan, your matching contributions will now be received in ArvinMeritor
stock and any employee contributions that you direct to an employer stock fund
will now be received in ArvinMeritor stock. In addition, your existing
balances in the Meritor stock funds will be converted to ArvinMeritor stock.

As an officer of ArvinMeritor, the following additional benefits will
continue:

- Club Membership
- Company Car
- Financial Counseling
- Annual Executive Physical Examination
- Personal Excess Liability Coverage
