     not employees of ArvinMeritor or any of its subsidiaries (Non-Employee
     Directors). The term "subsidiary" as used in the Plan means a corporation

     share, of ArvinMeritor (Shares). Shares to be delivered under the Plan may
     be authorized and unissued Shares, Shares held in treasury or any
     combination thereof. Shares with respect to the unexercised, undistributed
     or unearned portion of any terminated or forfeited award or grant made
     pursuant to the Plan shall be available for further awards or grants.

4.   ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by the Corporate Governance and Nominating
     Committee (the Committee) of the Board of Directors of ArvinMeritor (the
     Board), subject to the right of the Board, in its sole discretion, to
     exercise or authorize another committee or person to exercise some or all
     of the responsibilities, powers and authority vested in the Committee under
     the Plan. The Committee (or the Board or any other committee or person
     authorized by the Board) shall have authority to interpret the Plan, and to
     prescribe, amend and rescind rules and regulations relating to the
     administration of the Plan, and all such interpretations, rules and
     regulations shall be conclusive and binding on all persons.

5.   EFFECTIVE DATE OF THE PLAN.

     The Plan has been approved by the Board and shall be submitted to the
     shareowners of ArvinMeritor for approval at the Annual Meeting of
     Shareowners to be held in 2004 and, if approved by the shareowners, shall

     (a)  Annual Awards. Immediately following each Annual Meeting of
          Shareowners of ArvinMeritor, each Non-Employee Director who is elected
          a director at, or who was previously elected and continues as a

          Shares (Restricted Share Units) upon the terms and conditions set
          forth in the Plan and the applicable award agreement. The number of
          Restricted Share Units, if any, so awarded (the Annual RSU Amount)
          shall be fixed from time to time by the Board. Unless otherwise
          provided in the applicable award agreement, (i) each Restricted Share
          Unit shall be paid or settled by the issuance of one Share after the
          earliest of (A) six (6) years from the date of the award, (B) ten days
          after the Non-Employee Director retires from the Board after reaching
          age 72 and having served at least three years as a director or (C) the
          date the Non-Employee Director resigns from the Board or ceases to be
          a director by reason of the antitrust laws, compliance with
          ArvinMeritor's conflict of interest policies, death, disability or
          other circumstances that the Board determines not to be adverse to the
          best interests of ArvinMeritor and (ii) if the Non-Employee Director
          ceases to be a director prior to six years from the date of the award
          of the Restricted Share Unit for any reason other than as described in
          clause (i)(B) or clause (i)(C) above, such Restricted Share Unit will
          terminate and all right, title and interest of the Non-Employee
          Director thereunder will be forfeited. A participant shall not be
          required to make any payment for any Restricted Share Units or Shares
          delivered under this Section 6. Upon the delivery of Shares under this

          during the period after the Restricted Share Units are awarded and
          until the termination and forfeiture or payment and settlement
          thereof, to receive dividend equivalents in respect of such Restricted
          Share Units equal to the amount or value of any cash or other
          dividends or distributions payable on an equivalent number of Shares.
          Any such dividend equivalents shall be paid, with or without interest,
          as and when provided for in the applicable award agreement.

     (d)  Deferrals. If and to the extent provided for in the applicable award
          agreement and on such terms and conditions as may be set forth
          therein, a Non-Employee Director may from time to time elect in
          advance to defer the issuance and delivery of Shares otherwise
          issuable in respect of Restricted Share Units held by the Non-Employee
          Director.

          director after, that Annual Meeting may receive an award of Shares.
          The number of Shares, if any, so awarded (the Annual Share Amount)
          shall be fixed from time to time by the Board. A participant shall not
          be required to make any payment for any Shares delivered under this
          Section 7. Upon the delivery of Shares under this Section 7, the
          recipient shall have the entire beneficial ownership interest in, and
          all rights and privileges of a shareowner as to those Shares,
          including the right to vote the Shares and to receive dividends
          thereon.

     (b)  Discretionary Awards. At such times as the Board may determine, the
          Board may award to each Non-Employee Director, or to one or more
          designated Non-Employee Directors, such additional number of Shares as

          except that the Restricted Shares shall be held in book-entry accounts
          subject to the direction of ArvinMeritor (or if ArvinMeritor elects,
          certificates therefor may be issued in the recipient's name but
          delivered to and held by ArvinMeritor). Unless otherwise provided in
          the applicable award agreement, (i) the Restricted Shares so held
          shall be delivered to the Non-Employee Director and cease to be

          other circumstances the Board determines not to be adverse to the best
          interests of ArvinMeritor and (ii) if the Non-Employee Director ceases
          to be a director for any reason other than as described in clause
          (i)(B) or clause (i)(C) above prior to the date the restrictions set
          forth in the applicable award agreement lapse, all right, title and
          interest of the Non-Employee Director in such Restricted Shares shall
          be forfeited and such Restricted Shares shall be transferred to
          ArvinMeritor.

9.   STOCK OPTIONS.

     (a)  Annual Grants. Immediately following each Annual Meeting of
          Shareowners of ArvinMeritor, each Non-Employee Director who is elected
          a director at, or was previously elected and continues as a director
          after, that Annual Meeting may be granted an option (Option) to
          purchase Shares. The number of Shares subject to Options, if any, so
          granted (the Annual Option Amount) shall be fixed from time to time by
          the Board.

     (b)  Discretionary Grants. At such times as the Board may determine, the
          Board may grant to each Non-Employee Director, or to one or more
          designated Non-Employee Directors, Options for such additional number
          of Shares as the Board in its sole discretion shall determine.

     (c)  Exercise Price. The exercise price per Share for each Option granted
          under this Section 9 shall be one-hundred percent (100%) of the Fair
          Market Value (as defined below) of the Shares on the date of grant.


                                      B-4

     (d)  Exercise and Termination. The purchase price of the Shares with
          respect to which an Option or portion thereof is exercised shall be
          payable in full in cash, Shares valued at their Fair Market Value on
          the date of exercise, or a combination thereof. Unless otherwise
          provided in the applicable award agreement: (i) each Option may be
          exercised in whole or in part at any time after it becomes
          exercisable, (ii) each Option shall become exercisable in three
          approximately equal installments on each of the first, second and
          third anniversaries of the date the Option is granted and (iii) no
          Option shall be exercisable prior to one year or after ten years from
          the date of the grant thereof; provided, however, that (A) if the
          holder of an Option dies, the Option may be exercised from and after
          the date of the optionee's death for a period of three years (or until
          the expiration date specified in the Option if earlier) even if it was
          not exercisable at the date of death; (B) if an optionee retires after
          reaching age 72 and having served at least three years as a director,
          all Options then held by that optionee shall be exercisable even if
          they were not exercisable at the optionee's retirement date, provided,
          however, that each such Option shall expire at the earlier of five
          years after the date of the optionee's retirement or the expiration
          date specified in the Option; (C) if an optionee ceases to be a
          director by reason of disability or resignation from the Board for
          reasons of the antitrust laws, compliance with ArvinMeritor's conflict
          of interest policies or other circumstances that the Board determines
          not to be adverse to the best interests of ArvinMeritor, all Options
          then held by such optionee may be exercised from and after such
          termination date for a period of one year (or until the expiration
          date specified in the Option, if earlier), even if they were not
          exercisable at such termination date, unless otherwise determined by
          the Board; and (D) if an optionee ceases to be a director while
          holding unexercised Options for any reason not specified above, such
          Options are then void.

     (e)  Nonassignability. Except as otherwise provided in an applicable award
          agreement, Options granted under the Plan are not transferable other
          than (i) by will or by the laws of descent and distribution or (ii) by
          gift to the grantee's spouse or natural, adopted or step-children or
          grandchildren (Immediate Family Members) or to a trust for the benefit
          of one or more of the grantee's Immediate Family Members or to a
          family charitable trust established by the grantee or a member of the
          grantee's family.

10.  STOCK APPRECIATION RIGHTS.

     (a)  Annual Grants. Immediately following each Annual Meeting of
          Shareowners of ArvinMeritor, each Non-Employee Director who is elected
          a director at, or was previously elected and continues as a director
          after, that Annual Meeting may be granted Stock Appreciation Rights
          (as defined below). The number of Stock Appreciation Rights, if any,
          so

                                      B-5

          granted (the Annual SAR Amount) shall be fixed from time to time by
          the Board. Tandem SARs (as defined below) may be granted at the time
          of grant of an Option or at any time thereafter during the term of an
          Option.

     (b)  Discretionary Grants. At such times as the Board may determine, the
          Board may grant to each Non-Employee Director, or to one or more
          designated Non-Employee Directors, awards of such additional number of
          Stock Appreciation Rights as the Board in its sole discretion shall
          determine.

     (c)  Exercise and Other Terms. A Tandem SAR shall be exercisable only when
          and to the extent that the related Option is exercisable and in lieu
          thereof. Freestanding SARs (as defined below) may be granted on terms
          and conditions determined by the Committee, consistent with the
          provisions of the Plan. The payment to which the grantee of a Stock
          Appreciation Right is entitled upon exercise thereof may be made in
          Shares valued at their Fair Market Value on the date of exercise, or
          in cash or partly in cash and partly in Shares, as the Committee may
          determine. Upon exercise of a Tandem SAR and surrender of the related
          Option or part thereof, such Option, to the extent surrendered, shall
          not thereafter be exercisable, and the Shares covered by the
          surrendered Option shall not again be available for grants pursuant to
          the Plan. Upon exercise of a Freestanding SAR, any Shares delivered in
          payment thereof shall not again be available for grants pursuant to
          the Plan. Unless otherwise provided in the applicable award agreement:
          (i) each Freestanding SAR may be exercised in whole or in part at any
          time after it becomes exercisable, (ii) each Freestanding SAR shall
          become exercisable in three approximately equal installments on each
          of the first, second and third anniversaries of the date the
          Freestanding SAR is granted and (iii) no Freestanding SAR shall be
          exercisable prior to one year or after ten years from the date of the
          grant thereof; provided, however, that (A) if the holder of a
          Freestanding SAR dies, the Freestanding SAR may be exercised from and
          after the date of the Non-Employee Director's death for a period of
          three years (or until the expiration date specified in the
          Freestanding SAR if earlier) even if it was not exercisable at the
          date of death; (B) if a Non-Employee Director retires after reaching
          age 72 and having served at least three years as a director, all
          Freestanding SARs then held by that Non-Employee Director shall be
          exercisable even if they were not exercisable at the Non-Employee
          Director's retirement date, provided, however, that each such
          Freestanding SAR shall expire at the earlier of five years after the
          date of the Non-Employee Director's retirement or the expiration date
          specified in the Freestanding SAR; (C) if a Non-Employee Director
          ceases to be a director by reason of disability or resignation from
          the Board for reasons of the antitrust laws, compliance with
          ArvinMeritor's conflict of interest

                                      B-6

          policies or other circumstances that the Board determines not to be
          adverse to the best interests of ArvinMeritor, all Freestanding SARs
          then held by such Non-Employee Director may be exercised from and
          after such termination date for a period of one year (or until the
          expiration date specified in the Freestanding SAR, if earlier), even
          if they were not exercisable at such termination date, unless
          otherwise determined by the Board; and (D) if a Non-Employee Director
          ceases to be a director while holding unexercised Freestanding SARs
          for any reason not specified above, such Freestanding SARs are then
          void.

     (d)  Definitions. For purposes of the Plan, "Stock Appreciation Right" or
          "SAR" means a right granted to a Non-Employee Director (i) in
          conjunction with all or any part of any Option, which entitles the
          Non-Employee Director, upon exercise of such right, to surrender such
          Option, or any part thereof, and to receive a payment equal to the
          excess of the Fair Market Value on the date of such exercise of the
          Shares covered by such Option, or part thereof, over the purchase
          price of such Shares pursuant to the Option (a Tandem SAR) or (ii)
          separate and apart from any Option, which entitles the Non-Employee
          Director, upon exercise of such right, to receive a payment measured
          by the increase in the Fair Market Value of a number of Shares
          designated by such right from the date of grant of such right to the
          date on which the Non-Employee Director exercises such right (a
          Freestanding SAR).

11.  PRO RATA AWARDS.

     Each Non-Employee Director who is elected a director at any meeting of the
     Board shall receive effective immediately after that meeting an award of
     one hundred percent (100%) of the Annual RSU Amount, the Annual Share
     Amount, the Annual Restricted Share Amount, the Annual Option Amount and
     the Annual SAR Amount (the "Annual Grant Amount") if elected after an

     SHARES.

     (a)  Each Non-Employee Director may elect each year, not later than
          December 31 of the year preceding the year as to which deferral of
          fees is to be applicable, to defer all or any portion of the cash

          or Restricted Shares, valued at the Fair Market Value of the Shares on
          the date when each payment of such retainer amount would otherwise be
          made in cash. Such Restricted Share Units or Restricted Shares shall
          be the same as and subject to the same provisions as are applicable to
          Restricted Share Units and Restricted Shares that may be awarded
          pursuant to Sections 6 and 8, respectively.

     (b)  Each Non-Employee Director may elect each year, not later than

          Shares is to be made pursuant to Section 7(a), to receive the annual
          award in the form of Restricted Share Units or Restricted Shares. Such
          Restricted Share Units or Restricted Shares shall be the same as and
          subject to the same provisions as are applicable to Restricted Share
          Units and Restricted Shares that may be awarded pursuant to Sections 6
          and 8, respectively.

13.  AWARD AGREEMENTS.

     Each award or grant under the Plan may be evidenced by an award agreement
     setting forth such terms and conditions of the award or grant, not
     inconsistent with the terms of the Plan, as the Committee shall determine.
     In the event of any conflict between an award agreement and the Plan, the
     terms of the Plan shall govern.

14.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

     If there shall be any change in or affecting Shares on account of any
     merger, consolidation, reorganization, recapitalization, reclassification,
     stock dividend, stock split or combination, or other distribution to

     may deem appropriate under the circumstances.

     shareowner approval is necessary to comply with applicable requirements of
     the New York Stock Exchange. The Plan may also be terminated at any time by
     the Board. Termination of the Plan shall not affect the rights of
     Non-Employee Directors with respect to awards previously granted to them
     and all unexpired awards shall continue in force and effect after
