Dear Bill:

        This letter will confirm the substance of our conversations regarding

the mutual covenants and agreements contained herein, you and the Company agree
as follows:

          1. Pursuant to this Letter Agreement, you hereby resign voluntarily
from your employment with the Company, including your position as Vice Chairman
and President of the Company, and all your other positions with subsidiaries and
affiliates of the Company, which resignations will be effective as of August 18,
2001 (the "Resignation Date"). In addition, you hereby resign voluntarily,
effective as of the Resignation Date, from your position as a director of the
Company and as a director of any of its subsidiaries and affiliates. The Company
accepts your resignations set forth above.

          2. Effective upon the Resignation Date, the Company will pay or
provide to you the amounts or benefits described in Section 5(a) of the
Agreement by and among the Company (formerly named Mu Sub, Inc.), Arvin
Industries, Inc. and you dated as of the 6th day of April, 2000 (the "Employment
Agreement") as and when such payments or benefits would be paid or provided
under Section 5(a) of the Employment Agreement as if that Section were
applicable pursuant to the terms of the Employment Agreement, provided that for
purposes of determining the amount or other terms of any payment or benefit
under Section 5(a) of the Employment Agreement or the date of payment or
provision thereof, the term "Date of Termination" in Section 5(a) of the
Employment Agreement will be deemed to refer to the Resignation Date. You agree
that Schedule A attached hereto sets forth a complete and accurate list of all
payments and benefits to be paid or provided to you under this paragraph 2. In
addition, you acknowledge that you have received from the Company (i) detailed
calculations of all amounts set forth on Schedule A and Exhibit 2 and you agree
that such calculations are complete and accurate and (ii) a summary of retiree
health benefits.

          3. The provisions of Section 8, Section 9 and the first two sentences
of Section 7 of the Employment Agreement are incorporated herein as if set forth
in their

<PAGE>

entirety herein and as if those provisions were applicable pursuant to the terms
of the Employment Agreement, provided that the period applicable to your
obligations under Sections 9(b) and 9(c) of the Employment Agreement will be
deemed to be a period of one year following the Resignation Date and that it
shall not be deemed a violation of such Section 9(b) for you to (i) serve as a
non-employee director of any person, firm, corporation or other entity or (ii)
serve as a consultant to any person, firm, corporation or other entity that may,
when taken as a whole, engage in businesses that are in substantial and direct
competition with the Company, provided that your consulting services relate
solely to aspects of such entity's business that are not in substantial and
direct competition with the Company.

          4. The Company agrees to issue a press release on or promptly after
the Resignation Date regarding your resignation in the form attached hereto as
Exhibit 1.

          5. (a) You will not disparage, portray in a negative light, or take

divisions, parents or successors, whether public or private, including without
limitation, in any and all interviews, oral statements, written materials,

Internet- or intranet-related sites; provided that this paragraph 5(a) will not
apply to the extent you (i) are seeking to enforce your rights under this Letter
Agreement or (ii) are making truthful statements when required by order of a
court or other legal body having jurisdiction, provided you have given the
Company reasonable prior notice of, and a reasonable opportunity to contest,
such order. In the event of a breach or threatened breach of this paragraph
5(a), you agree that the Company will be entitled to injunctive relief in a
court of appropriate jurisdiction to remedy any such breach or threatened breach
and you acknowledge that damages would be inadequate and insufficient.

             (b) The Company will not, and will take reasonable measures to
cause its senior officers (senior vice presidents or higher level officers) and

without limitation, in any and all interviews, oral statements, written
materials, electronically displayed materials and materials or information
displayed on Internet- or intranet- related sites; provided that this paragraph
5(b) will not apply to the extent the Company (i) is seeking to enforce its

opportunity to contest, such order. In the event of a breach or threatened
breach of this paragraph 5(b), the Company agrees that you will be entitled to
injunctive relief in a court of appropriate jurisdiction to remedy

date hereof, including without limitation, any and all matters relating to your
employment by the Company and its predecessors and the cessation thereof, any

        You understand that you have the right to take up to twenty-one (21)

any such revocation, this Letter Agreement (with the exception of paragraph 14
below, which will remain in full force and effect) will be void ab initio and
the Company will have no obligation to you hereunder. If seven (7) days pass
following your execution hereof without such notice of revocation, this Letter

ever had, now have or may hereafter have, against the Executive Released Parties
or any of them arising out of or by reason of any act or omission undertaken by
you in the scope of your duties with the Company and its affiliates from the
beginning of the world to the date hereof; provided, however, that the Company
does not release, acquit or discharge the Executive Released Parties from: (i)
any of your express obligations arising out of or in connection with this Letter
Agreement; and (ii) any of your acts or omissions involving fraud, dishonesty,
gross negligence or willful malfeasance. It is understood that nothing in this

wrongdoing being expressly denied.

filings with the Securities and Exchange Commission.

          15. The Company will cause to be maintained for a period of six years
after the Resignation Date your coverage under the current policies of
directors' and officers' liability insurance maintained by the Company (provided
that the Company may substitute therefor policies of at least the same coverage
and amounts containing terms and conditions which are, in the aggregate, no less
advantageous to you) with respect to claims arising from facts or events that
occurred on or before the Resignation Date; provided, however, that in no event
shall the Company be required to expend in any one year an amount in excess of
200% of the annual premiums currently paid by the Company for such insurance;
and, provided, further, that if the annual premiums of such insurance coverage
exceed such amount, the Company shall be obligated to obtain a policy with the
greatest coverage available for a cost not exceeding such amount.

          16. You represent and warrant that you are entering voluntarily into
this Letter Agreement, and that, except as set forth herein, no promises or
inducements for this Letter Agreement have been made, and you enter into this
